Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a cleaning machine for shoes such as sneakers.

(B) Prior art As shown in FIG. 4, a rotating shaft 42 is provided at the center of a cleaning tank 41, and a hanger 4 is attached to this shaft 42.
Japanese Utility Model Publication No. 11176/1983 discloses a device in which shoes are hung on a tub and rotated, and scrubbed with a brush 44 on the inner wall of the tank.

However, even if the rotating shaft 42 is reversed, this product will only wash the high part of the shoe's instep, and will mostly wash the low part of the shoe's instep (near the sides), the toes, and the heel. I can't.

(c) Problems to be solved by the invention The present invention makes it possible to uniformly clean the entire shoe.

(c) Means for solving the problem The solution according to the present invention is to install a rotating shaft upright at the bottom of the tank, and to install a horizontal shaft protruding from the inner circumferential surface of the tank at intervals on the circumferential side of the shaft. Main brushes are provided above and below, and auxiliary brushes facing upward are provided at the inner bottom of the tank or below the rotating shaft.

(E) Function A rotating water flow is generated in the tank, and while the shoes are floating in the tank, the main brush on the rotating shaft washes around the shoes, and the auxiliary brush washes the front and rear ends of the falling shoes.

(f) Example To explain based on the drawings, 1 is a machine frame of a shoe washing machine, inside of which is an outer tank 2 that serves as a water receiver, and a hanging rod 3...
It is supported elastically by Reference numeral 4 denotes an inner tank serving as a dewatering/cleaning tank that is pivotally supported within the outer tank 2. A large number of dewatering holes are provided in the peripheral wall of the inner tank 4, and a balance ring 5 is attached to the upper part. Reference numeral 6 denotes a cylindrical rotating shaft rotatably installed at the center of the bottom of the inner tank 4. A circular base plate 7 is integrally provided at the bottom of the shaft in the form of a flange, and the inner surface of the inner tank 4 is attached to the circumferential side. Main brushes 8 that protrude long and laterally are provided vertically, and auxiliary brushes 9 that are short and protrude upward are provided on the substrate 7.

Here, each of the brushes 8 and 9 is a bundle of thin wires, and each of the main brushes 8 is arranged at intervals of 90 degrees of rotation angle on the circumferential surface, is linear from the bottom to the top, and has a protruding degree. It is provided so that it has a large taper such that it becomes larger toward the top. Then, the overall planar view is formed into a so-called cross shape, or the rotation angle is set at intervals of 90 degrees at the bottom of each shaft, but each is formed into a curved or spiral shape toward the top. On the other hand, the auxiliary brushes 9 are arranged at 90 degree intervals between at least the lower portions of the main brushes 8, but their planar shape may be V-shaped or I-shaped. Also, the board 7
If the auxiliary brushes 9 are not provided, the auxiliary brushes 9 may be provided directly on the inner bottom of the tank 4.

10 is a drive motor, which connects the inner tank 4 and the rotating shaft 6.
(substrate 7) via a pulley belt and power transmission mechanism 11, and during cleaning, the rotating shaft 6 is rotated at low speed and reversed left and right at a cycle of about 0.3 seconds of rest and about 0.8 seconds of rotation, and when dewatering, the inner tank 4 and rotating shaft 6 are simultaneously rotated in one direction at high speed.

Reference numeral 12 denotes a lid body for closing the shoe entrance/exit 13 formed above the inner tank 4, 14 an operating section installed at the upper rear part of the machine frame 1, and 15 a water supply solenoid provided in the operating section 14. 18 is a water supply channel from the water supply electromagnetic valve 15 to the inner tank 4; 17 is a drainage channel for discharging the water in the outer tank 2; and 18 is a drainage electromagnetic valve interposed in the drainage channel 17.

Incidentally, the amount of water supplied to the inner tank 4 is detected by a known detection means that combines an air trap, a pressure switch, etc.

To explain the next operation, shoes A such as sneakers are placed between the rotating shaft 6 and the inner surface of the inner tub 4, and a start switch (not shown) is operated. Then. Under program control by a microcomputer, water is automatically supplied to a predetermined location and detergent is automatically supplied, after which the cleaning process begins. In this cleaning process, the drive motor 10 reverses the rotating shaft 6. Note that, when the cleaning process is completed, the program is designed to sequentially execute the steps of draining, water supply, rinsing, draining, and dewatering.

In this cleaning process, the main brushes 8 generate a reverse water flow in the tank, and wash the floating shoes A by scrubbing them laterally. In particular, the peripheral side of shoes A can be washed well. On the other hand, the auxiliary brushes 9 are rubbed by the main brushes 8, and when the shoes A move and fall between the brushes and fall onto the substrate 7, they rub in a point contact state. When bubbles form in the tank due to the rotating water stream, shoes A...
The buoyancy of the bubbles acts on the main brush 8.
Because the space between them is narrow, shoe A that falls into this space stands up with its front and rear ends (toe and heel) up and down. Therefore, the front and rear ends of the shoes A come into contact with the auxiliary brushes 9 and are rubbed, and are thoroughly washed. In particular, the tapered shape of the tips of the main brushes 8 acts to hold down the shoes A downward, increasing the contact (friction) between the shoes A and the auxiliary brushes 9, thereby increasing the cleaning effect.

FIG. 3 shows another embodiment in which the protruding shape and dimensions of the main brushes 8 are modified from the above-described embodiment. Here, the taper of the tip of the main brush 8 is kept to about 10 mm, and a space is provided between the tip and the inner surface of the tank to facilitate the rotation of the shoes A, which will be described later. Each brush 8..., 9... is made of 60 nylon. In this embodiment, the above-mentioned interval is set to 0.3 to 0.5 of the dimension between the outer surface of the rotating shaft 6 and the inner surface of the inner tank 4. Specifically, 0.5 is adopted, and an average of 80
mm. Therefore, the length of the main brush 8 is also 80 mm, and due to the taper, it is 85 mm at the top and 75 mm at the bottom. For this reason, even cloth shoes with a length of 29 cm and a foot circumference of 285 mm as specified by JIS (5033) can rotate if the main brush 8, which is flexible due to its length, is bent.

During the actual cleaning operation, the shoes A fall onto and come into contact with the short auxiliary brush 9, and are blown upward by the elasticity of the brush, whereupon the main brush 8 rotates.
It rotates due to the rotational force caused by... As a result of shoe A... rotating on its axis, brushes 8..., 9 cover even more details.
It comes into contact with ... and is rubbed at that time, thereby cleaning the entire area uniformly over every detail. Making shoes A easier to stand due to the buoyancy of the bubbles and reversing the axis of rotation 6 further promote the rotation of shoes A, which flew upwards.

By making the auxiliary brushes 9 harder than the main brushes 8, relatively heavily soiled toe and heel areas can be cleaned more effectively.

Further, if blades for stirring the cleaning liquid are provided on the rotating shaft 6, the cleaning power will be further improved.

Furthermore, the pebbles etc. that were attached to the shoes. Although they fall onto the substrate 7 and are discharged together with the cleaning liquid, if a filter is provided to collect the pebbles, etc., there is no risk of poor drainage.

(g) Effects of the invention According to the invention, the main brush on the rotating shaft scrubs the entire side surface of the shoe uniformly, and the auxiliary brush scrubs the toes and heel areas, which are relatively heavily soiled. It is possible to provide a shoe cleaning machine that can uniformly wash the entire shoe and has a high cleaning effect.

Moreover, since the degree of protrusion of the main brush is increased as it moves upward, the main brush acts to press down on the shoes, strengthening the contact between the shoes and the auxiliary brush, further improving the cleaning effect. can.
