)の接点は通常へ復帰する。Next, the present invention will be explained in detail based on the above configuration and the electric circuit shown in FIG. In the standby state, the water level of the heating tank (2) is maintained at the position indicated by the dashed line (X). When the extraction switch (18) is pressed here, the first relay (20) is energized and switches its contact from the normally closed contact (20A) to the normally closed contact (20B) and closes the self-holding contact (20C). maintain self. This results in
The water supply solenoid valve (10) is energized, the solenoid valve (10) is opened, and pressurized water passes through the water supply pipe (9) to the heating tank (2).
is supplied with water. The water level in the heating tank (2) rises due to this water supply, and when it reaches a level slightly below the level at which the siphon effect starts, the reed switch (15) closes and the delay timer (21) starts, and a predetermined period of time (e.g. 3 seconds), the time switch (21A) closes and the second relay (22) is energized.Then, the contact is switched from the normally closed contact (22A>) to the normally closed contact (22B), and the other normally closed contact (22B) is switched. The closing contact (22C) opens.As a result, the power supply to the water supply solenoid valve (10) is cut off, and the water supply operation to the heating tank 2) is completed.At this time,
The first relay (20) is de-energized and the first relay (20) is de-energized.

熱湯はサイフオン管(3)を通って抽出される。Thus, the siphon effect starts within the 3 second delay time set by the delay timer (21). That is, when the water level exceeds the top (3B>) of the siphon pipe (3) during this period, the siphon effect starts and the hot water in the heating tank (2) is extracted through the siphon pipe (3).

、、L E D (19)が点灯する。By the way, when the water supply solenoid valve <10) is energized by pressing the extraction switch (18), heavy pressure is simultaneously applied to the signal input circuit of the low water pressure detection circuit. That is, current flows through the L E D (23A) of the photocoupler (23>), which causes the phototransistor (23B) on the secondary side to
turns on. Then, the base potential of the transistor (24) decreases, and the transistor (24) is turned on. By turning on this transistor (24), the timer circuit (25)
Heavy pressure is applied to the machine and the timer starts operating. The timer time is set by a variable resistor (26) and a capacitor (27).This timer time is the time from when the extraction switch (18) is pressed until the siphon effect starts when the water supply pressure is normal (example). If the water supply pressure is 0.
5kg/CIT+! 3θ seconds) for a longer time (e.g. 4
5 seconds). Therefore, after the set time has elapsed, the voltage at the output terminal (25A) of the timer circuit (25) becomes rH, and the drive transistor (28) turns ON.
,, L E D (19) lights up.

(25)は不動作となり、ゼロにセットされる。Thus, a voltage is always applied to the low water pressure detection circuit, and a voltage is applied to the timer circuit (25) only when the water supply solenoid valve (10) is energized, so that it can operate. Therefore, when the water supply time is shorter than the timer operation time, that is, when the water supply pressure is normal, the voltage application to the photocoupler (23) is stopped when the water supply solenoid valve (10) is de-energized. Therefore, the phototransistor (23B) and the transistor (24) are turned off, and the timer circuit (25) becomes inactive and set to zero.

), the output of the timer circuit (25) becomes rH.
, and as long as the power is not cut off, L E D (1
