Description

BEVERAGE DISPENSING VALVE
TECHNICAL FIELD
The present invention relates to a beverage dispensing valve which
is disposed at a beverage supply apparatus such as a hot and cold water
generator or a hot and cold water purifier or the like, and more particularly,
to a beverage dispensing valve which allows to alternately dispense and
cut off a beverage according to the pushing operation of a beverage
discharge actuating lever of a push type exposed to the front surface.
Further, the present invention relates to a beverage dispensing
valve which is provided with a safety discharge function suitable upon
discharging hot water from a hot and cold water generator or a hot and cold
water purifier.
BACKGROUND ART
Typically, a beverage dispensing valve dedicatedly discharging hot
water/cold water is disposed at a hot and cold water generator that
supplies natural raw water stored in a storage tank as hot water or cold
water or at a hot and cold water purifier that purifies ground water or city
water by many filtering processes and supplies it as cold water or hot
water. In a beverage dispensing valve according to a conventional example,
a beverage discharge on-off portion is disposed within a cavity in a
vertical direction of the front side of a valve body, in which one end of a
feed hose connected to a cold water tank or a hot water tank is watertightly
connected to the back side, and the lower end of the inside of the cavity in
the front side of the valve body is defined as a beverage discharge outlet
and a cap member is detachably coupled to the upper end of the inside of
the cavity.
The beverage discharge on-off portion includes: a shaft of a vertical
elevating operation which is disposed within the cavity in a vertical
direction of the valve body, some parts of the upper side penetrating the
center of the cap member and being externally exposed; an outlet on-off
member made of, for example, silicon, which is coupled to the lower end of
the shaft and opens and closes the beverage discharge outlet in
conjunction with the vertical elevating operation; an elastic spring which is
disposed on the outer periphery of the shaft between the bottom face of
the cap member and drops the shaft elevated for the discharging of a
beverage to the original position; and a beverage discharge actuating lever
which is forward/backward movably coupled to an upper part of the shaft
exposed to the upper side of the cap member so as to form a point of application in the upper side of the cap member.
Therefore, in the beverage dispensing valve according to the
conventional example, when the beverage discharge actuating lever is
pulled forward or pushed backward, the shaft is elevated to allow the outlet
on-off member coupled to the lower end of the shaft to open the beverage
discharge outlet of the valve body, and, accordingly, a beverage introduced
from the cold water tank or the hot water tank via the feed hose is
discharged through the beverage discharge outlet.
If the operation of the beverage discharge actuating lever is
released after a beverage of a required quantity has been dispensed, the
shaft is dropped to the original position by an elastic force of the elastic
spring, and accordingly the beverage discharge outlet of the valve body is
closed to stop the dispensing of the beverage.
In the beverage dispensing valve, however, the beverage discharge
actuating lever is located in a manner that a point of application is formed
on the upper end of the valve body, or is formed in a manner to be extended
to the outer periphery of the valve body. Thus, in a case that the lever is
actually disposed on a hot and cold water generator or a hot and cold water
purifier as a water supply apparatus, the operation of the valve becomes
inconvenient and the beverage discharge actuating lever has to be continuously maintained in an operational state in order to dispense a
required quantity of cold water or hot water.
Further, since the point of application of the beverage discharge
actuating lever is formed on the upper end of the valve body, a sufficient
clearance for placement is required in order to dispose the valve at the
beverage supply apparatus, which is difficult in terms of the design of the
beverage supply apparatus.
Moreover, hot water dispensed from the corresponding beverage
supply apparatus is in a state that is heated at a high temperature, there
always exists the possibility of a safety accident such as getting burnt.
Hence, as for the beverage dispensing valve for dispensing hot
water from the beverage supply apparatus, the design of a safety discharge
structure is needed.
Additionally, in consideration of the advantages in terms of design of
a hot and cold water generator or a hot and cold water purifier, there is a
recent need for the discharging of only a chose beverage, in which a
plurality of kinds of beverages is provided with respect to a single
beverage dispensing valve, or for the discharging of mixed water. In this
case, also, a structure for accomplishing a safe dispensing function in case
hot water is included in the beverages is needed. Accordingly, it is a primary object of the present invention to
provide a beverage dispensing valve which is improved in convenience and
the applicability to a beverage supply apparatus by disposing a beverage
discharge actuating lever of push type on the front surface of a valve body
so as to alternately dispense and stop a beverage according to a pushing
operation, allowing to continuously dispense the beverage even if the
beverage discharge actuating lever is not continuously pushed with the
beverage discharge actuating lever being operated in a beverage
dispensing state, and pushing the beverage discharge actuating lever again
to stop the dispensing of the beverage.
It is another object of the present invention to provide a beverage
dispensing valve which is properly adapted to a beverage supply apparatus,
including a cold water and hot water generator or a cold water and hot
water purifier, especially designed to achieve a safety dispensing of hot
water.
It is another object of the present invention to provide a beverage
dispensing valve, which is adapted to a beverage supply apparatus,
including a cold water and hot water generator or a cold water and hot
water purifier, is designed so as to discharge a plurality of kinds of
beverages selectively or in combination from a single valve body. It is still another object of the present invention to provide a
beverage dispensing valve which enables to check the amount of water
stored in a storage tank disposed in a beverage supply apparatus by
disposing a storage indicator on a valve body.

Additionally, a beverage discharge actuating lever 140 of push
button type is disposed on the front surface of the valve body 110 defining
the beverage discharge space portion 112. The beverage discharge
actuating lever 140 is coupled so that the upper end thereof is forward and
backward rotatable by a rotary axis 142 as shown in Fig. 2.
Preferably, a lever reinforcing member 144 for preventing deformation upon operating the corresponding beverage discharge
actuating lever 120 is mounted on the front surface of the beverage
discharge actuating lever 140.
Further, a beverage discharge control portion 146 is provided at the

operation of the beverage discharge actuating lever 140.
Referring to Fig. 3, the beverage discharge control portion 146
includes: a cylindrical guide member 148 with an inner cavity setting the
dispensing/stopping of a beverage as a flange end 148A at one side is
fixedly coupled to a concave portion 102A formed on the front surface of
the valve bpdy 110 in the back of the beverage discharge actuating lever
140; a beverage discharge/stop position guide member 150 received in the
guide member 148, with one end contacting the rear surface of the
beverage discharge actuating lever 146, and determining the
dispensing/stopping position of a beverage in response to the operation of
the beverage discharge actuating lever 146; and a beverage

of a beverage by the shaft 126, with one end being received in the
beverage discharge/stop position guide member 150 and the other end receiving a small diameter end 126a of the shaft 126.
Referring to Figs. 4a and 4b, a plurality of concave and convex
portions for guiding a beverage discharge/stop position is formed on the
inner surface of the cylindrical guide member 148. In each of the concave
and convex portions, a concave portion 148c is formed between a first
convex portion 148a and a second convex portion 148b, and a beverage
discharge stop guide recess 148d determining a beverage discharge/stop
position is formed between the first convex portion 148a of the
corresponding concave and convex portion and a second convex portion of
an adjacent concave and convex portion.
Additionally, the upper end of the first concave portion 148a is
formed by a sloping surface 154a processed to be sloping in one direction,
and the second convex portion 148b and the concave portion 148c are
formed by continuous sloping surfaces 154b and 154c so as to determine a
beverage discharge/stop position.
Referring to Fig. 5, the beverage discharge/stop position guide
member 150 will be described. The beverage discharge/stop position
guide member 150 is located in a manner that one end 156 can be
penetrated through the guide member 148 and be tangential to the
beverage discharge actuating lever 140, and that a plurality of projections 150a located in the concave portion 148c and beverage discharge stop
guide recess 148d of the guide member 148 are formed on the other end
thereof. The front ends of the projections 150a are processed to be sloped
at a predetermined angle in both sides.
Preferably, a cover member 142B made of, for example, soft silicon
for preventing leakage is interposed between the beverage discharge
actuating lever 140 and the one end 156 of the beverage discharge/stop
position guide member 150. The cover member 142B is fixedly coupled to
the corresponding valve body 110 by a fixing member 142C in the concave
portion 102A of the valve body 110.
Referring to Fig. 6, the beverage discharge/stop operation member
152 will be described. One end 152a of the beverage discharge/stop
operation member 152 is received within the beverage discharge/stop
position guide member 150, and a shaft housing 152c for housing the small
diameter end 126a of the shaft 126 is formed at the inside of the other end
152 thereof. Beverage discharge/stop positioning flaps are formed at a
constant interval on the outer circumferential surface of the shaft housing
.152c. The front end 158a of each of the beverage discharge/stop
positioning flaps 158 is sloped in a direction and at an angle both
corresponding to the first and second convex portions 148a and 148b of the guide member 148 and to the sloping surfaces 154a to 154c of the
concave portion 148c.
Fig. 7 and Figs. 8a to 8f are views for explaining a mounting
structure of the beverage discharge actuating lever 140 and the lever
reinforcing member 155. Lever reinforcing member housing recesses 160
and 162 for housing the lever reinforcing member 144 are formed on the
upper end of the front surface of the beverage discharge actuating lever
140 in order to prevent the occurrence of deformation during a pushing
operation or during a restoration to the original position.
Preferably, the middle part of both side faces of the lever
reinforcing member 144 as shown in Fig. 8a is formed as a stopping portion
164 (refer to Fig. 8b) by being curved to a predetermined depth, and,
correspondingly, a first fixed flap 160 with first stopping projections 160a
formed inward at upper and lower sides thereof are formed at the middle
part of the lever reinforcing member housing recess 160 (refer to Fig. 8c).
Additionally, a stopping recess 166 is formed at both sides of the
stopping portion 164 of the lever reinforcing member 144 (refer to Figs. 8d
and 8e), and, correspondingly, a second fixed flap 166 with second
stopping projections 162a formed inward and received in the stopping
recess 166 is formed at the lever reinforcing member housing recess 152 formed at both sides of the lever reinforcing member housing recess 160
of the middle part. The inside faces of the second stopping projections
162a are tapered at a predetermined degree of slope (refer to Fig. 8f).
Referring to Fig. 9, beverage passage holes 132a for passing a
beverage are formed at the shaft fixing/guide member 132, and a shaft
guide hole 132b for guiding and fixing the shaft 126 is formed at the center
thereof.
Therefore, to help understanding of the operation of the beverage
dispensing valve of the above-described structure according to the
present invention, the structure of essential parts of the beverage
dispensing control portion 146 will be described with reference to Figs.
10a to 1Od shown by planar development
Firstly, at an initial position where the dispensing of a beverage is
stopped after the beverage dispensing valve of this invention has been
assembled into a shape as shown in Fig. 1, the shaft 126 is maintained at a
beverage discharge/stop position by an elastic force of the elastic spring
136.
That is, in a case that the beverage discharge actuating lever 142 is
incapable of pushing operation, the plurality of projections 150a of the
beverage discharge/stop position guide member 150 is located in the concave portions 148c and beverage discharge stop guide recesses 148 of
the guide member 148 and each of the beverage discharge/stop positioning
flaps 158 of the beverage discharge/stop operation member 152 is
maintained received in each of the beverage discharge stop guide recesses
148d of the guide member 148 (refer to Fig. 10a).
In this case, the beverage discharge on-off member 130 coupled to
the shaft 126 closes the communicating port 116 functioning as a beverage
passage port by an elastic force of the elastic spring 136, thereby making
a beverage not dispensable.
In this state, if the beverage discharge actuating lever 142 is pushed
backward for dispensing a beverage, the beverage discharge/stop position
guide member 148c is pushed backward as the projections 150a are guided
in the concave portions 148c and beverage discharge stop guide recesses
148d of the guide member 148, and accordingly the beverage
discharge/stop positioning flaps 158 of the beverage discharge/stop
operation member 152 is also interlockingly pushed backward.
Then, the shaft 126, in which the small diameter 126a is coupled to
the beverage discharge/stop operation member 152, is also pushed
backward, thus the communicating port 116 closed by the beverage
discharge on-off member 130 is opened and accordingly a beverage is dispensed through the beverage discharge outlet 118 of the valve body
110.
In a case that such a beverage dispensing operation is achieved,
with the projections 150a of the beverage discharge/stop position guide
member 150 moving backward while pushing the beverage discharge/stop
positioning flaps 158 of the beverage discharge/stop operation member
152 (as shown in Fig. 10), when the projections 150a become in the
position corresponding to the sloping surfaces 154b of the second convex
portions 148b of the guide member 148, the beverage discharge/stop
positioning flap 158 of the beverage discharge/stop operation member 152
is slid on the slope of the front ends 150b of the projections 150a of the
beverage discharge/stop position guide member 150 and on the sloping
surfaces 154b of the second convex portions 148b, and resultantly the
beverage discharge/stop operation member 152 causes a rotary operation
(as shown in Fig. 10c). Accordingly, the beverage discharge/stop
positioning flaps 158 of the beverage discharge/stop operation member
152 are stopped and supported on the sloping surfaces 154b of the
concave portions 148c of the guide member 148 (precisely, on the
boundary parts of the first convex portions 148a). Accordingly, even if the
operation of the beverage dispensing actuating member 142 is released, the shaft 126 is not restored to the original position, and the opening state
of the communication port 116 is maintained to maintain the dispensing of
the beverage.
Upon this, if the beverage discharge actuating lever 142 is pushed
again, the projections 150a of the beverage discharge/stop position guide
member 150 pushes backward the beverage discharge/stop positioning
flap 158 of the beverage discharge/stop operation member 152 by the
same operation as above.
If the beverage discharge/stop positioning flap 158 is pushed to
such a degree that it becomes in the position corresponding to the sloping
surfaces 154a of the first convex portions 148a, the beverage
discharge/stop positioning flaps 158 of the beverage discharge/stop
operation member 152 are slidably moved along the sloping surfaces 154a
of the first convex portions 148a (i.e., the beverage discharge/stop
operation member 153 is rotated) and inserted into the beverage discharge
stop guide recesses 148d (refer to Fig. 10a). Accordingly, as the shaft 126
moves forward by an elastic force of the elastic spring 136, the beverage
discharge on-off member 130 closes the communicating port 116 to stop
the dispensing of a beverage.
By the above operation, the operation of dispensing or stopping the beverage according to a number of operations of the beverage discharge
actuating member 40 is accomplished.
Further, referring to Fig. 1, it is more preferable to additionally
dispose a leakage prevention member 170 at an upper side of the beverage
discharge space portion 112 in order to prevent leakage through a screw
coupling portion of the cap member 122.
Fig. 11 shows a schematic perspective view of a beverage
dispensing valve with a safety discharge structure according to a second
preferred embodiment of the present invention.
Referring to Fig. 11, the beverage dispensing valve according to the
present invention includes-" a valve body 200; a cap member 202 which is
detached from and coupled to an upper side of the valve body 200! a
beverage discharge lever 204 of which an upper central portion is located
on the cap member 202 and which opens and closes a beverage discharge
path formed within the valve body 200," and a safety discharge actuating
portion 206 disposed on the front surface of the valve body 200 to enable
a pushing operation and for controlling an operable state of the beverage
discharge lever 204.
A fixed portion 202a attached to the front surface of a
corresponding beverage supply apparatus as a hot beverage flows internally is formed in the rear side of the valve body 200. A beverage
discharge outlet 208 for discharging a beverage upon operating the
beverage discharge lever 204 as the beverage discharge lever 204 is
converted into an operable state by the safety discharge actuating portion
206 is formed in the lower side of the valve body 200.
According to an internal structure of the beverage dispensing valve
as shown in Fig. 12, a first shaft 210 elevated for achieving the discharging
of a beverage (especially, hot water) through the beverage discharge
outlet 209 according to an operational state of the beverage discharge
lever 204 is vertically extendedly disposed in the valve body 200. A lever
coupling recess 212 for pivotally housing a coupling projection (not shown)
projecting on both faces of the central essential part of the beverage
discharge lever 204 is formed on both sides of the upper end of the first
shaft 210.
Here, an upper side portion including the lever coupling recess 212
of the first shaft 210 is exposed upward through the central part of the cap
member 202 upon coupling the corresponding beverage dispensing valve,
and a coupling projection (not shown) of the beverage discharge lever 204
is coupled to the lever coupling recess 212 of the first shaft 210 on the cap
member 202. Further, referring to Fig. 12, a first elastic spring 214 functioning to
be dropped to the original position with the first shaft 210 elevated is
provided on the outer periphery of the first shaft 210. On end of the first
elastic spring 214 is supported on the bottom surface of the cap member
202 and the other end thereof is supported on a predetermined position of
the first shaft 210.
Referring to Figs. 13a and 13b, the lower ends of a leakage
prevention members 218 formed of, for example, soft silicon, are coupled
to leakage prevention member fixing ridges 216 formed at a constant
interval at a predetermined position of the first shaft 210 in order to
prevent a beverage from being leaked upward.
Further, a through hole 220 is formed on the central region of the
first shaft 210. The through hole 220 is preferably applicable if it is an
elliptical or polygonal shape.
Further, an outlet on-off member 224 formed of, for example,
silicon for opening and closing the beverage discharge outlet 208 is
coupled to an outlet on-off member coupling ridge 222 formed on the
lower end of the first shaft 210. A stopper projection 226a with a
predetermined length and height for locking/unlocking a second shaft to be
described later is formed on one side of a flange portion 226 formed in the upper side of the outlet on-off member coupling ridge 222.
Further, referring to Fig. 12, the safety discharge actuating portion
206 includes: a safety lever 230 exposed to the front surface of the valve
body 200 and for controlling an operable state of the beverage discharge
lever 204; a second shaft 232 located at the back of the safety lever 230
and extending in a horizontal direction orthogonal to the first shaft 210; a
second elastic spring 234 for restoring the second shaft 232 to the original
position; a fixed guide member 236 for guiding the back of the second shaft
232; and a beverage path on-off member 238 coupled to a predetermined
position of the second shaft 232 and for opening and closing a discharge
path of a beverage.
Here, the safety lever 230 and the lever reinforcing member 300
coupled to the safety lever 230 have the same construction and coupling
structure as the structure explained in Fig. 4 and Figs. 5a to 5f. Also, the
fixed guide member 236 is constructed similarly to the structure illustrated
in Fig. 9 on the whole.
Referring to Fig. 14, the second shaft 232 is cut so that both side
faces of the central region thereof correspond to the shape of the through
hole 220 formed on the center of the first shaft 210, to thus be formed as a
rotation prevention surface 238. Not only the second shaft 232 is not made arbitrarily rotatable by the inner shape of the through hole 220 of the first
shaft 210 and the rotation prevention surface 238 of the second shaft, but
also the arbitrary rotation of the first shaft 210 is prevented not to cause a
shift of the beverage discharge lever 204, thereby ensuring the safety of
the operating position of the beverage discharge lever 204.
Further, an insert projection 242 corresponding to a stopper
projection 226a formed on the first shaft 210 is formed at an essential part
240 defined in the lower side of the second shaft 232. The right side face
of the insert projection 242 in the drawing is tapered and cut at a
predetermined angle.
Further, a beverage path on-off member coupling ridge 244 fixedly
coupling the beverage path on-off member 238 is formed on the back of
the left side of the essential part 240 in the drawing of the second shaft 232.
An elastic spring support portion 246 supporting one end of the second
elastic spring 234 is formed on the back of the beverage path on-off
member coupling ridge 244.
Referring to Fig. 12, a cap-shaped member 248 made of soft
material (for example, silicon) is provided between the rear surface of the
safety lever 230 and the front end of the second shaft 232 for preventing a
beverage leakage by watertightly shielding an opening area formed on the front surface of the valve body 200 so as to enable a pushing operation of
the second shaft 232 and for preventing the falling-out of the second shaft
232. The cap-shaped member 248 is watertightly mounted on the valve
body 200 by a fixed ring 250 provided on the outer circumferential surface,
and, if necessary, additionally provided with a proper shielding member
including an O-ring.
According to the beverage dispensing valve with a safety discharge
structure of the above-described structure according to the present
invention, in a state of having been assembled in such a shape as shown in
Fig. 12, as the first shaft 210 is maintained in the lowered original position
in ordinary times, the path of a beverage is blocked by the beverage path
on-off member 238 on the second shaft 232 and the beverage discharge
outlet 208 is maintained at a blocked state by the outlet on-off member
224.
Therefore, in a case that only the beverage discharge lever 204 is
actuated, the first shaft 210 is elevated to open the beverage discharge
outlet 208. But, since the beverage path is blocked by the beverage path
on-off member 238 on the second shaft 232, the beverage is not
dispensable.
Further, if only the safety lever 230 is pushed, the second shaft 232 is pushed backward to open the blocked beverage path by the beverage,
path on-off member 238. But, since the beverage discharge outlet 208 is
becomes in a closed sate by the outlet on-off member 224 coupled to the
first shaft 210, the beverage is not dispensable.
With respect to this, in a case that the beverage discharge lever 204
is actuated after the safety lever 230 is pushed, or in a case that the safety
lever 230 is pushed after the beverage discharge lever 204 is pushed, the
first shaft 210 is elevated by the operation of the beverage discharge lever
204 and the second shaft 232 is pushed backward, and accordingly the
stopper ridge 226a of the first shaft 210 is positioned by insert projection
242 on the second shaft 232.
Therefore, the beverage path and beverage discharge outlet 208 in
the valve body 200 are all opened to dispense a beverage. If the beverage
is hot water, it is dispensed only when the safety lever 230 and the
beverage discharge lever 204 are all in an operational state, thus ensuring
a safety discharge of hot water.
Here, in a state that the stopper ridge 226a of the first shaft 210 and
the insert projection 242 of the second shaft 232 are engaged to each other,
even if the operation of the safety lever 230 was released, the beverage
discharge function is not stopped to thus enable a continuous beverage discharge.
And, if the elastic force of the first elastic spring 214 is set
somewhat stronger than that of the second elastic spring 234, in case of
releasing the operation of the beverage discharge lever 204, the first shaft
210 is moved downward to the original position by the elastic force of the
first elastic spring 214 to thus seal the beverage discharge outlet 208. If
the first shaft 210 is dropped to the original position, the insert projection
242 of the second shaft 232 is released and the second shaft 232 is also
moved forward and returned to the original position by the elastic force of
the second elastic spring 234, thereby maintaining the beverage discharge
in an off state.
Thus, according to the beverage dispensing valve with a safety
discharge function according to the preferred second embodiment of the
present invention, the discharge of a beverage is achieved only when the
beverage discharge lever 204 and the safety lever 230 are simultaneously
or sequentially operated, thereby making it possible to prevent a safety
accident such as getting burnt even though the beverage was hot water.
Figs. 15 to 17 are views showing a beverage dispensing valve with
a safety discharge function according to a third embodiment of the present
invention. Although the second embodiment assumes such a structure that dispenses one beverage, the third embodiment assumes such a structure
that dispenses a plurality of kinds of beverages by a single valve body.
That is, not only a single beverage discharge outlet 500 is formed at
a single valve body 400, but also a single beverage discharge lever 600 for
operating the discharge of a plurality of kinds of beverages is coupled
thereto. On the front surface thereof, a plurality of safety discharge
actuating portions 700,800 and 900 are designed in separate spaces for
optionally discharging a plurality of kinds of beverages.
Here, a beverage supply tube engaging parts 502, 504 and 506 for
engaging a beverage supply tube (or beverage supply hose) for supplying a
plurality of kinds of beverages are provided at the rear side of the valve
body 400. Preferably, the beverage supply tube engaging part 502 is
formed integral with the corresponding valve body 400, and it is
advantageous in terms of design that the beverage supply tube engaging
parts 504 and 506 are designed in a manner that are detachable while
maintaining a predetermined angle outwardly with respect to the beverage
supply tube engaging part 502. However, the present invention is not
necessarily limited to the scope of designing a detachable structure, but
also assumes an integral formation method.
In this case, it is preferable to adapt O-rϊngs 508 and 510 as watertight members for preventing a leakage to the engaging positions of
the beverage supply tube engaging parts 504 and 506.
Here, if it is arranged to flow ordinary temperature water, hot water
and cold water into the beverage supply tube engaging part 502, the
beverage supply tube engaging part 504 and the beverage supply tube
engaging part 506, respectively, this reduces the influence of the
temperature of the individual beverages on each other and this is preferred
upon supplying mixed water.
Moreover, separate spaces corresponding to the safety discharge
actuating portions 700, 800 and 900 are provided in the valve body 400,
prevent the formation of moisture (or dew) on the outer surface due to cold
water in the summer, and, more preferably, contain a foaming agent for
temperature compensation.
Additionally, on the whole, the safety discharge actuating portions
700, 800 and 900 are constructed in a manner similar to the construction of
Fig. 11. As shown in Fig. 17, although a first shaft 620 engaged to a
coupling projection 622 of the beverage discharge lever 604 and for
opening and closing the beverage discharge outlet 602 and a structure of
an elastic spring 624, a leakage prevention member 626 and an outlet
on-off member 628 are formed in the same manner as the first embodiment on the whole. But, a second shaft supporting portion 630 supporting second
shafts 702, 802 and 902 provided at safety discharge actuating portions
700, 800 and 900 has a modified structure.
That is, the second shaft supporting portion 630 is formed integrally
to the first shaft 620 and is provided with shaft through holes 632a, 632b
and 632c for passing the second shafts 702, 802 and 902 of the safety
discharge actuating portions 700, 800 and 900 through (refer to Fig. 16).
Therefore, in the beverage dispensing valve with a safety discharge
function according to the third embodiment of the present invention, for
example, when any one of the safety discharge actuating portions 700, 800
and 900 and the beverage discharge lever 604 are pushed, as the first shaft
620 is elevated similarly to the second embodiment and the second shafts
702, 802 and 902 of the pushed safety discharge actuating portions 700,
800 and 900 are pushed backward, the beverage path is opened and
accordingly a chose beverage is dispensed through the beverage
discharge outlet 500.
Here, although the second shaft supporting portion 630 is elevated
integrally with the elevation of the first shaft 620, an unoperated beverage
path of the safety discharge actuating portions 700, 800 and 900 allows the
second shaft to be maintained in the original position, thus not discharging the corresponding beverage.
With respect to this, in a case that a plurality of safety discharge
actuating portions 700 and 800; 800 and 900; or 700 and 900 are
simultaneously operated or all of them are operated, each beverage as
properly mixed water is dispensed through a single beverage discharge
outlet 500.
Subsequently, in the beverage dispensing valve with a safety
discharge function according to the third embodiment of the present
invention, the discharge function for a plurality of kinds of beverages and
the safety discharge function for each individual beverage are ensured. In
a case that the plurality of kinds of beverages include hot water, a sudden
hot water discharge state is avoided to prevent a safety accident such as
getting burnt, especially, as the valve body is doped with a foaming agent,
the phenomenon of moisture or dew formation due to cold water is
eliminated and a heat insulation effect is achieved.
Fig. 18 shows a beverage dispensing valve with a safety discharge
function according to a fourth preferred embodiment. The beverage
dispensing valve of the fourth embodiment is a modified example of the
second embodiment.
That is, in the second embodiment, a sealed cap-shaped member 248 is provided between the safety lever 230 constituting the safety
discharge actuating portion 206 and the second shaft 232 tangential to the
safety lever 230 in the second embodiment. On the other hand, in the third
embodiment, the center of the cap-shaped member 248 is perforated to
make the front end of the second shaft 232 directly tangential to the rear
surface of the safety lever 230 and a group of ring type projections 232A
are formed at a predetermined position of the second shaft 232 as shown in
Fig. 19a so that ring type recesses 232B are formed on the center. By
mounting an O-ring 248A to the ring type recesses 232B for preventing
leakage, the abrasion of the cap-shaped member 248 is prevented even if
the safety lever 230 was frequently operated, and a leakage is also
prevented by the O-ring 248A.
With respect to this, the center of the cap-shaped member 248 is
perforated to make the front end of the second shaft 232 directly tangential
to the rear surface of the safety lever 230 and a ring type recess 232D for
mounting an O-ring 248A is formed at a predetermined position of the
second shaft 232 as shown in Fig. 19b. Accordingly, the abrasion of the
cap-shaped member 248 is prevented even if the safety lever 230 was
frequently operated, and a leakage is also prevented by the O-ring 248A.
Consequently, in the fourth embodiment of the present invention, also, the hot water safety discharge function is ensured by the same
operation as the second embodiment.
Fig. 20 shows a beverage dispensing valve with a safety discharge
function according to a fifth embodiment of the present invention. The fifth
embodiment shows a modified example for obtaining a structure
corresponding to the third embodiment by adapting the second shaft 232,
0-ring 248A and cap-shaped member 248 of the fourth embodiment.
That is to say, multiple safety discharge actuating portions 700, 800
and 900 for optionally discharging a plurality of kinds of beverages with
respect to a single beverage discharge lever 600 are designed as separate
spaces.
With respect to the safety discharge actuating portions 704A, 804A
and 904A, cap-shaped members 704, 804 and 904 with the centers of the
front ends opened are adapted. To a predetermined position of the second
shafts 702A, 802A and 902A, O-rings 704B, 804B and 904B watertightly
contacted to the inner surface of the cap-shaped members 704A, 804A and
904A are mounted.
Therefore, in the fifth embodiment, the same operation and
functions as the third embodiment are ensured so as to dispense any one of
cold water/hot water/purified water or a mixed beverage thereof when a specific safety discharge lever is operated and the beverage discharge
lever 600 is operated.
Fig. 21 shows another example of the beverage discharge levers
204 and 600 adapted to the second to fifth embodiments. While the
beverage discharge levers 204 and 600 adapted to the second to fifth
embodiments are arranged in the outer side of the valve body, the
beverage discharge lever 600A shown in the same drawing is operable on
the upper end of the valve body and the beverage discharge lever 600A
also makes it possible to obtain the operation and effect desired in each of
the embodiments also by the beverage.
Fig. 22 shows a construction in which a storage indicator for
identifying a storage capacity of a storage tank stored in a beverage supply
apparatus (for example, a cold and hot water generator or cold or hot water
purifier) in the beverage dispensing valve (representatively having the
construction as shown in Fig. 15) according to the first to fourth
embodiments.
That is, referring to Fig. 22, a water flow port 1000 is perforated on
an upper end position adjacent to the fixed portion 202a of the valve body
200 and a cylindrical portion 1002 of a predetermined height is formed
integral with the valve body 200, A screw form is formed on the outer circumferential surface of the cylindrical portion 1002.
A leakage prevention member 1004 is arranged on the outer
circumference of the water flow port 1000 on the inner side of the
cylindrical portion 1002, and a storage indicator 1006 is vertically
disposed to the upper side of the leakage prevention member 1004. The
form of an extended diameter 1006a for vertical fixing is formed on the
lower side of the storage indicator 1006. Preferably, the extended
diameter 1006 on the lower side of the storage indicator 1006 is formed
with a diameter with which it can be housed inside the cylindrical portion
1002.
Here, preferably, the center portion of the leakage prevention
member 1004 and the lower end of the storage indicator 1006
communicate with the water flow port 1006.
Moreover, a storage indicator fixing member 1008 is screwed to the
outer side of the cylindrical portion 1002 for vertically fixing the storage
indicator 1006.
Therefore, in the structure as shown in Fig. 12, the beverage fed
from the storage tank with the beverage path blocked by the beverage path
on-off member 238 is introduced into the storage indicator 1006 through
the water flow port 1000, thereby enabling to check the amount of the beverage stored in the storage tank.
Although the present invention has been fully described by way of
examples with reference to the accompanying drawings, it is to be noted
that various changes and modifications will be apparent to those skilled in
the art. Therefore, unless such changes and modifications depart from the
scope of the present invention, they should be construed as being included
therein. For instance, the number of safety discharge actuating portions
suggested in the second embodiment is involved with only hot water and
cold water or the number can be increased or decreased as needed.
Further, of course, the storage indicator is changeable into the
shape of a temperature gauge for indicating the temperature of cold water
or hot water.
As described above, according to the beverage dispensing valve of
the present invention, since the beverage discharge actuating lever is
disposed on the front surface of the valve body in a pushing method to thus
achieve the control of a beverage discharge, the operational convenience
and the applicability to a beverage supply apparatus are improved in
comparison with the case in which the beverage discharge lever is
disposed on the upper side of the valve body and the case in which the
beverage discharge lever is disposed on the outer side of the valve body. In the structure in which the beverage dispensing valve according to
the present invention is provided with a safety discharge function, the
discharge of a beverage is achieved only when the safety lever is operated
interlockingly with the beverage discharge lever. Accordingly, it is
possible to suppress the occurrence of a safety accident due to a sudden
discharge of hot water.
Further, it is possible to optionally dispense a plurality of kinds of
beverages with the plurality of kinds of beverages introduced into a single
valve body. In this case, in a case that the beverages include hot water, hot
water is dispensed only when the beverage discharge lever and the safety
lever are operated interlockingly. Accordingly, it is possible to suppress
the occurrence of a safety accident and it is enabled to dispense mixed
water by a single valve.
Moreover, as a foaming agent is added to the valve body, the
phenomenon of moisture or dew formation due to a temperature difference
is prevented and a heat insulating effect is also dramatically enhanced.
Additionally, the amount of a beverage stored in the storage tank
can be checked by the storage indicator disposed on the upper side of the
valve body.
