Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a washing machine for shoes such as sneakers.

(B) Prior Art Japanese Patent Application Laid-Open No. 58-203737 discloses a brush that moves up and down to scrub the area around shoes. However, with this product, when the brush is raised as the cleaning progresses and bubbles begin to form, the bubbles may pop out.

(c) Problems to be solved by the invention The present invention aims to suppress foam flying out of the tank and to clean the entire shoe uniformly and effectively.

(d) Means for solving the problem The shoe cleaning machine of the present invention has a motor-driven rotating shaft erected at the inner bottom of the cleaning tank, and a plurality of thin wires on the circumferential side of the rotating shaft. The brushes are provided horizontally and vertically, and the density of the brushes provided above the rotating shaft is relatively lower than that of the brushes provided below the rotating shaft. be.

(e) Effect: In other words, shoes that contain water sink to the bottom of the cleaning tank, and the dense brush thoroughly scrubs them. at the same time,
At the bottom of the cleaning tank, a dense brush stirs the cleaning solution to promote foaming, which gives the shoe buoyancy and causes it to rotate, bringing the entire circumference of the shoe into contact with the brush.

On the other hand, in the upper part of the cleaning tank, the density of the brushes is low, so the degree to which the brushes stir the cleaning liquid is small, and the rate of foaming is also small.

(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, which is pivotally supported within the outer tank 2, and has a large number of dewatering holes in its peripheral wall and a balance ring 5 attached to its 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 projecting laterally toward the substrate 7 are provided vertically with a predetermined width, and short auxiliary brushes 9 projecting upward are provided on the substrate 7.

Here, each of the brushes 8 and 9 is a bundle of a plurality of thin wires, and each of the main brushes 8 is arranged at intervals of 90 degrees of rotation angle on the circumferential surface, and is arranged in a straight line from the bottom to the top. and is tapered so that the degree of protrusion becomes larger as it goes upward. The rotation angle is set at 90 degree intervals at the bottom of each shaft,
It has a shape that draws a curve or a spiral toward the top, and with the washing water level WL or its vicinity as the boundary, the fine lines are coarse in the upper 8', and about three times as dense as the upper part in the lower 8''. That is, the main brushes 8 have a coarse upper part 8' and a denser lower part 8''.
On the other hand, the auxiliary brushes 9 are also arranged at 90 degree intervals between at least the lower portions of the main brushes 8, and have a V-shaped or I-shaped planar shape. Furthermore, if the substrate 7 is 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.

12 is a lid for closing the shoe entrance 13 formed above the inner tank 4; 14 is an operating section disposed at the upper rear part of the machine frame 1; 15 is a water supply solenoid provided in the operating section 14. 16 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.

In addition, the water supply level to the inner tank 4, that is, the washing water level WL
is detected by a known detection means that combines an air trap, a pressure switch, etc.

Next, the operation will be described. 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, W.
Water is automatically supplied to L. and detergent is automatically supplied, after which the cleaning process begins. In this cleaning process, the drive motor 10 reverses the rotating shaft 6. It should be noted that the program is so designed that when the cleaning process is completed, the following processes are executed in order: draining, water supply, rinsing, draining, and dewatering.

In this cleaning process, the main brushes 8 generate a reversed water flow in the tank, move freely, and wash the shoes A, which contain water and are located at the bottom of the tank, with the high-density part 8''.Especially, the shoes The peripheral part of A... can be thoroughly washed.
On the other hand, the auxiliary brushes 9 are rubbed by the main brushes 8, and move to rub the shoe A that has fallen onto the substrate 7 by entering between the brushes in a point contact state. Main brush 8...
As the cleaning progresses, the lower part 8'' of the main brush 8 often generates bubbles in the tank, but the bubbles exert a buoyancy force on the shoe A, so the shoe A receives a reversing force, and the entire body gradually moves to the main brush 8.
It comes into contact with the lower 8'' of the... and is evenly washed with strong cleaning power.

The low-density upper portions 8' of the brushes 8 rotate simultaneously during cleaning and act to suppress the floating of the shoes A, and have a weak cleaning power. Therefore, on the contrary, the foaming power is weak, and the foam that rises to the water surface due to rotation is not foamed any further, nor is it blown away by the rotational force. Rather, the bubbles that have risen are suppressed from foaming in this low-density portion 8'.

In this way, shoes A... are thoroughly and evenly washed by the high-density part 8'' of the brush 8..., and the bubbles stirred by the high-density part 8'' are washed by the upper low-density part 8'. Further foaming can be suppressed.

(g) Effects of the invention In the configuration of the shoe washing machine of the invention, the density of the brushes at the top of the rotating shaft is reduced, so the degree of stirring of the cleaning liquid by the brushes at the top of the cleaning tank is small, and foaming is prevented. The percentage of people who do so is small.

Therefore, when the brush rotates, this rotational force is less likely to cause bubbles to scatter outside the tank.

In addition, the circumferential surface of shoes that tend to sink to the bottom of the tank can be
Since the shoes are scrubbed with a high-density brush, the entire shoe can be cleaned evenly and efficiently.
