However, the drying process as a post-treatment of the cleaning operation takes more than several times the normal cleaning process, and there are many questions about its effectiveness, so the market is under pressure to solve these problems. It was.

  Bed mattresses are usually made of polyester or other fibrous material with a thickness of about 100mm, but conventional dryers typically apply hot air to the surface or dry by natural convection of dry air. Therefore, it takes a long processing time to dry the inside of the mattress. In contrast, after washing the mattress, it is dehydrated using centrifugal force, and then hot air is strongly applied to the mattress surface for drying, or hot air is applied to the bedding after dehydration so as to penetrate the bedding. The application of the “futon forced dryer” that promotes drying has been adopted as a means for solving the above problems.

  These slightly advanced methods can achieve a certain effect of shortening the drying time compared to the conventional method, but for example, the method using centrifugal force has deformation of the mattress, and in the application of `` futon forced dryer '' However, it does not function sufficiently for mattresses to be dried and has many problems such as large and expensive equipment. It was the cause that the spread did not progress.

  Examples of prior arts about dryers such as these various mechanical mattresses are as follows. However, none of the above-mentioned known structures, including the above-mentioned known structures, can sufficiently meet the needs, and high-speed drying of mattresses and the like. And the technical content was also insufficient for the purpose of obtaining cleanliness and hygienic effect efficiently by disinfection treatment.
