Description

Shoe Washer {FOOTWEAR WASHER}

The present invention relates to a shoe washer that effectively washes various types of shoes, including sneakers or boots, in a mechanical manner using a brush.

The shoe protects the feet from the outside when walking and mitigates the impact. It is worn on the foot for direct contact with the outside environment, so it is easily dirty. Dirty shoes are clean and hygienic through regular washing process. Can be worn.

Professional shoe laundering, which requires the washing of many different shoes, such as a laundering shop, usually involves removing the basic debris from the shoe, a soaking step called for a period of time soaked in warm water with a detergent, brush, brush or high pressure water. Washing step to clean the outer skin and inner skin including upper, rinse step using clean water, dehydration step to dehydrate using dehydrator, drying step to dry using dryer, etc. It is made of a packaging step, the shoe washing machine according to the present invention is a device applied to the washing step of the shoe washing process.

A normal shoe is made up of an upper which is attached to the opening of the upper part of the upper part and a sole attached to the lower part of the middle to protect the lower part of the foot and the ankle. The upper is made of leather or fibres, the midsole is a combination of a sole made of polyurethane or ethylene vinyl acetate foam and a rubber sole, and a soft cloth-covered structure in contact with the foot. It is possible to wash efficiently by changing the cleaning method according to the characteristics of the material because it forms the shape of the shoes by attaching it by bonding or sewing using different materials, and the adhesive used for the adhesion of the material Because of the weakness of impact, improper washing method causes damage of adhesive and material, affecting the life and washing quality of shoes, and these structural characteristics become characteristics of shoe washing different from general clothes washing methods.

Conventionally, there is a method of washing shoes, washing by hand, washing in a drum, washing with a brush, washing with high pressure water, using a brush and high pressure water at the same time, and applying each washing method. Various types of devices have been proposed for this purpose.

The method of washing by hand is a method used traditionally, in which a shoe is immersed in water made of detergent, soaked for a predetermined time, and then rubbed with a brush or the like to remove dirt. This can be done by checking with human hands, thus improving the quality of the washing, reducing the damage to shoes, or requiring a lot of manpower when washing a large number of shoes, such as a specialized shoe cleaner. Not suitable for professional laundry washing shoes.

The washing method is to apply the cleaning principle of the cloth to the shoes. The washing method is applied to the rotating drum type washing machine with detergent and rotates so that the washing is performed by friction contact between the washing water and the shoes. It can be washed, and in some cases, it provides a possible advantage to the dehydration process, but there is a limit to the removal of foreign matter caught in the slits or fine grooves for aesthetics formed in the manufacturing step on the outer surface such as upper or midsole. In addition, there is a disadvantage that the seams or attachment parts are easily dropped due to repeated impact during the washing process, which shortens the life of the shoes. When the upper material is made of leather or synthetic leather, or boots type shoes are disclosed in Patent 10-1161507. As described above, there was a disadvantage in that a small amount of washing was performed using a dedicated washing machine such as a boot attachment.

The method of cleaning by rubbing with a brush is to use a device equipped with a brush on a rotating shaft to put the detergent in the detergent and rub the soaked shoe against the rotating brush. The use of a brush driven by rotational power provides the advantage of increasing the efficiency of washing, but as a shoe washing machine, there is a limit to the improvement of cleaning quality and efficiency.

For example, Republic of Korea Patent No. 10-1016814 proposes a shoe washer to wash by rubbing with a brush. As shown in FIG. 1, the main body 100 includes a pollutant removing tank 300 and a washing tank 500, and the washing tank 500 is driven by a motor 510 to rotate the outside and the inside of the shoe. As a structure having a washing brush 531, 533, 535 for washing, water is introduced into the pollutant removal tank 300 by the washing water supply 310, and the introduced water is heated to an appropriate temperature by the heater 330. After heating, the shoes are put in and the soil is removed at the same time as the soak, and in the next step has a configuration principle of washing the shoes by friction contact with the cleaning brush (531) (533) (535).

The structure removes the contaminants of the shoes by the washing water heated to the proper temperature by the heater and includes a contaminant removal tank 300 which can be called for a predetermined time, thereby providing convenience of use. The washing quality is low and washing satisfaction is low, such as wear caused by friction between the washing brush 531 (533) (535) and the shoe, and the synthetic leather or stitching thread constituting the shoe is damaged. There was a downside. In addition, the outer cleaning brush 531, the inner cleaning brush 533, the fine partial cleaning brush 535 is configured to be operated by the independent motor 510 and the switch pedal 130, respectively, the configuration is complicated, the inner cleaning Solsol (533) is a soft cloth that forms the lining of the shoe, but most of the cloth is a component that hardly needs to be used because it is easier to wash with high-pressure washing water and excellent washing ability, and the drive rotary shaft is intact to the worker. Since it is exposed, there was a problem that can not exclude the occurrence of safety accidents, such as winding clothing of the worker.

The method of washing with high pressure water removes contaminants by spraying the high pressure wash water directly onto the shoe while the shoe is called. As described above, the cleaning effect is high in the case of the outer skin of the shoe and the cloth. Although it provides an efficient advantage, there is a limit to cleanly remove contaminants attached to the gaps or grooves applied to the shoes.

The method of using the brush and the high pressure water at the same time is to use a water blasting device for washing as shown in the Republic of Korea Utility Model Publication 1995-0005675 brush by spraying high-pressure washing water with friction shoes in contact with the shoe on the rotary brush Although there is an advantage to increase the washing effect by the high-pressure wash water, it is difficult to secure the field of vision during the operation by the scattering of high-pressure water, there is a problem that the high-pressure wash water directly acts on the operator's hand, causing high work fatigue and induces hypnosis.
