Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cleaning / disinfecting or drying means for cleaning / disinfecting a wheelchair, storing a wheelchair in a case forming a cleaning tank built in the apparatus body, and pumping a cleaning liquid by a circulation pump to eject it from an injection nozzle. Further, the present invention relates to a technique for effectively and automatically performing a series of steps of rinsing, disinfection, and drying with a relatively simple device, while performing circulatory washing with this fountain flow.
[0002]
[Prior art]
Conventionally, as general equipment cleaning devices, various products such as tableware cleaning, filth cleaning, surgical equipment, electronic parts, etc. are commercialized and marketed, but these cleaning devices are relatively simple materials, respectively. The function is limited so as to be adapted to a specific object to be cleaned having a shape. In addition, as a means for cleaning an object to be cleaned, there are many examples of techniques that are common sense since ancient times, such as using a fountain flow from a liquid jet nozzle and a cleaning liquid discharged from the fountain flow containing a detergent. To do. Furthermore, means for washing a wheelchair or storing a disabled person in a wheelchair in a housing and washing with a fountain flow from a liquid jet nozzle is already known.
[0003]
In these conventionally known means and apparatuses, the object to be cleaned has a complicated structure like a wheelchair and is composed of various kinds of materials such as metal, resin, cloth, rubber, etc., and the effect of cleaning / disinfection is enhanced. It was difficult. For this reason, a high-pressure jet shower system that has been considered for obtaining a certain effect even when used for washing a wheelchair has already been publicly known. In this system, for example, a high-pressure compressor, a complicated piping system, and a control system are used. It was necessary to use a large amount of water, and it was expensive and uneconomical.
[0004]
On the other hand, a proposal was made to disassemble the wheelchair into wheels, seats, armrests, handles, pedestals, etc., and to clean and reassemble with a general washing machine. There was a fear that it could not be adopted at all.
Therefore, the current state of the cleaning work is that all parts are manually removed by hand, and all the steps of so-called wiping are performed manually using tools such as cloth. The cleaning process in the growing wheelchair has been laborious and expensive, and as a result has become a very cumbersome task with variations.
[0005]
Furthermore, when it is necessary to disinfect a wheelchair, a method of partially wiping with a cloth soaked with a disinfectant such as alcohol, hydrogen peroxide solution or sodium hypochlorite aqueous solution is generally used. . In addition, as a large-scale apparatus, a method of leaving it in a room filled with a poison gas such as ethylene oxide vapor or formaldehyde vapor for a certain period of time and disinfecting only the surface has been adopted. The treatment in an extremely incomplete state has many problems in terms of hygiene and work man-hours.
[0006]
In recent years, as a means for solving the above problems, a cleaning / disinfecting machine for the purpose of cleaning / disinfecting a wheelchair has been proposed and is already known as a prior art. This has a certain effect on the purpose, but there is insufficient content as a function of the product, and many improvements are required.
[0007]
Examples of the known object cleaning means are not limited to enumeration, but the following patent document exists as a known example having a relatively common purpose with the present invention.
