Description

  The present invention relates to a technique for removing dirt adhering to welfare care equipment such as a mattress for a bed, and in particular, the mattress is cleaned and rinsed from both the front and back sides and processed into a clean state in a short time. The present invention relates to means for configuring the automatic washing machine.

The need to keep welfare care equipment such as mattresses for beds clean is steadily increasing due to needs related to the improvement of the medical treatment and care environment that has occurred with the progress of an aging society. Hygiene was very unsatisfactory because it was rarely cleaned or disinfected or was performed with very poor manual labor. For this reason, keeping the mattress clean is a urgent social requirement for improving the care and medical environment for the sick, handicapped and elderly, and preventing infection.
In order to meet these needs, devices that automatically clean the entire mattress have been developed in recent years, and attempts have been made to introduce them into the market. The current situation is not.

Bed mattresses are usually made of polyester and other fibrous materials with a thickness of about 100 mm. When used for a long period of time, dirt from food and body fluids adheres and penetrates not only the surface but also the inside. It is well known that it becomes difficult to clean easily.
Conventionally, in order to keep the mattress clean, it was unavoidable to use a scrubbing brush or the like to wash hands and then use a sunbath or other means for drying. -The disinfection effect was insufficient, and it was extremely difficult to remove dirt that had penetrated into the fiber. In addition, it takes a long time to dry the rinsing liquid that has penetrated into the fiber after washing.

  For the purpose of solving the above problems, a machine that automatically cleans the surface of the mattress by spraying a cleaning solution made of an aqueous solution of a detergent and rinsing, dehydrating, etc. is proposed and being put into practical use. In these machines, the mattress is flattened in the horizontal direction and set in the machine. The main feature is to obtain a cleaning effect by permeating into the water.

  According to these means, there is relatively little variation in the cleaning effect compared to hand washing, and labor saving can be achieved, but there is not enough cleaning effect on the surface where the cleaning liquid is not applied first, and there is an installation space for other machines where cleaning unevenness occurs. There is a problem that it is large and expensive, and is completely unsuitable for cleaning welfare care equipment other than mattresses. Further, there are adverse effects such as deformation of mattresses and deterioration of materials, which has been a cause of the spread of such machines in the market.

  Examples of these prior arts for various types of mechanical mattress cleaning / dehydration are as follows. However, none of the above-mentioned known structures, including the above-mentioned known structures, can sufficiently meet the needs, and the mattress is cleaned by automatic cleaning. However, the technical content was insufficient for the purpose of obtaining sanitary effects.
