It is provided in the section. The driving drum 20 and the driven drum 21
Has a rotating shaft 24 inside and the belt member 19 outside.
A feed dog 25 having a tooth profile that meshes with is integrally provided, and the feed tooth 25 is formed of an elastic material so that the rotary raised cloth 18 can easily follow the uneven state of the surface to be cleaned. ing.

Further, the driving drum 20 and the driven drum 21
The main driving drum 20 behind the suction port 14 will be described.
The rotation center of the driven drum 21 in front of the suction port 14 is located (A) above the surface to be cleaned,
In other words, the lower outer peripheral surface of the rotary raised cloth located on the driven drum 21 side in contact with the surface to be cleaned is set higher than the lower outer peripheral surface of the rotary raised cloth located on the driving drum 20 side.

Reference numeral 26 denotes a bearing member 22 for holding the rotation of the driving drum 20 so that a cut pile-shaped rotary raised cloth made of a spun cloth of ultrafine fibers comes into contact with the surface to be cleaned at a constant pressure. The driving drum 20 is a spring member that is urged toward the surface to be cleaned. The driving drum 20 is vertically movable with respect to the surface to be cleaned. .

Reference numeral 28 denotes a motor which is a drive source for rotationally driving the driving drum 20, and a large pulley 2 is used to rotate the rotational force from a small pulley 29 through a belt 30 which is a power transmission means.
It is transmitted to 3. Reference numeral 31 is a control circuit portion of the motor 28, and 32 is a power cord for supplying power. Reference numerals 33 and 34 denote wheels provided in front of and behind the suction tool body 10 so that the suction port 14 is located at a constant distance from the surface to be cleaned.

Next, the operation and action of this embodiment will be described. When cleaning the wooden floor, plastic flooring, tatami mat, etc. by connecting and fitting the connecting pipe 17 of the suction tool body 10 to the hose and extension tube (not shown) connected to the electric vacuum cleaner body, The rotary raised cloth 18 rotatably driven by the motor 28 comes into contact with the surface to be cleaned, and sliding is performed sequentially without being restricted by the cleaning operation. At this time, the contact with the surface to be cleaned is a cut pile spun cloth made of ultra-fine fibers, and the elasticity of the raised cloth is extremely soft. This is a drive source that can be eliminated and that rotates regardless of the reciprocating movement of the suction tool body 10. The cleaning source that is particularly dirty is capable of wiping, sweeping, and polishing the surface to be cleaned. The surface can be efficiently cleaned in a short time.

Further, the positional relationship in which the belt-shaped rotary raised cloth 18 contacts the surface to be cleaned is set such that the front part is set higher than the rear part with respect to the direction of forward movement. On the other hand, it is possible to ride up and move smoothly like the action of a caterpillar, and it is possible to perform cleaning work efficiently and without discomfort.

Further, the feed drum 25 portion of the driving drum 20 and the driven drum 21 arranged inside the rotary raised cloth 18 is made of an elastic material, and the rotary raised cloth 18 against the irregularities of the surface to be cleaned. Since the action of pressing is freely possible and the follow-up of the rotary raised cloth 18 is extremely improved, uneven cleaning can be eliminated and the cleaning work can be performed efficiently and neatly.

Further, a spring member 26 for biasing in the direction of the surface to be cleaned is formed with respect to the bearing member 22 for holding the rotation of the driving drum 20 arranged in the rear of the rotary raised fabric 18, and the surface to be cleaned is On the other hand, since the cut pile-shaped rotary raised cloth 18 made of a spun cloth of ultrafine fibers is brought into contact with each other under a constant pressure, the frictional force is made uniform irrespective of the state of the surface to be cleaned, so that the suction tool has excellent durability. Is what you can get.

Next, a method for manufacturing and processing the rotary raised cloth 18 will be described. In FIGS. 4 to 5, the rotary raised cloth 18
Is composed of a base cloth 35 portion and a napped portion 36 in which ultrafine fibers are partially spun on the base cloth 35 and processed into a cut pile shape. The napped portion 36 is spun so as to be diagonally finished with a constant width (B). At the same time, the width of the center part (C) is 3
The raised portions 36 are formed on the left and right, and are formed in five parts so that the center portion is symmetrical and form one block. A plurality of this one block are collected and spun.
Further, the width (D) of the one block is the rotary nap 1
The width is set to be the same as the width of No. 8, the length is set to be the same as the entire length of the outer peripheral portion of the belt material 19, and the base cloth 35 is cut.

In the next step, a pair of processing jigs 37 used when the rotary raised cloth 18 is stuck is prepared inside the belt material 19 to hold the belt material 19 in rotation, and then the outer peripheral surface of the belt material 19. The adhesive is evenly applied on the upper surface, and the rotating nap cloth 18 is sequentially adhered. At this time, the belt material 19 is rotating at a low speed by the processing jig 37, and the rotating nap cloth 18 is pressed from the tip portion. While being bonded, tension (F) is applied to the terminal end to stabilize the work.

For this reason, an ultra-fine fiber is spun in an inverted V shape so that dust gathers in the central portion in the direction of rotation of the belt-shaped rotary raised cloth 18, and dust on the surface to be cleaned is removed. The spinning shape of the rotary napped cloth 18 that can be efficiently sucked and removed by the action of gathering in the central portion of the suction port 14 can be provided.

Further, also in the method of manufacturing and processing the belt-shaped rotary napped cloth 18, the base cloth 35 and the napped portion 36 spun with ultrafine fibers are partially spun, and the base cloth 35 is cut. At the same time, in the next step, the surface of the belt material 19 is glued with an adhesive, so that it is possible to efficiently manufacture and process with high quality at low cost.

[0034]

As is apparent from the above-described embodiments, according to the present invention, a rotating nap cloth, which is formed by forming a nap cloth using ultrafine fibers in an annular width, is arranged inside the suction port. The driven drum and the driven drum are configured to rotate freely.The contact of the rotating brushed fabric with the cleaning surface is extremely soft, and the soft touch provides the same effect as a snare, which can damage the surface. In addition, the drive source that rotates regardless of the reciprocating motion of the suction tool body is installed inside, and the effect of wiping, sweeping, and polishing the surface to be cleaned can be obtained. The surface can be efficiently cleaned in a short time .
