[0004]
[Problems to be solved by the invention]
Since the hot water for rinsing stored in the hot water storage tank is heated to a high temperature of about 80 ° C. to 90 ° C. and used for rinsing, the heat of the hot water storage tank heated by the hot water for rinsing is high. Then, it is conducted to the slide rail through the support base, and the slide rail is also heated. However, as shown in FIG. 5, the conventional slide rail 1 is formed in a substantially rectangular block shape by cutting a synthetic resin material, and thus has a small surface area, a small contact area with the surrounding air, and is difficult to dissipate heat. It was a shape and it was easy to store heat in the slide rail 1 itself. When the slide rail 1 accumulates heat in this way, the slide rail 1 made of synthetic resin becomes brittle due to deformation such as bending or a decrease in physical properties due to the heat, causing damage. Therefore, it is necessary to use a material having high heat resistance so that it can withstand high temperatures. In this case, however, the material cost increases. Even if the heat resistance is improved, the slide rail 1 itself has a shape in which it is difficult to dissipate heat. Therefore, the heat of the slide rail 1 is conducted to the bottom plate and disposed close to the bottom plate. It is also pointed out that the piping outside the machine and other members outside the machine are affected by heat, such as bending due to heat and becoming brittle due to deterioration of physical properties.
