For making each water conservancy diversion layer 2 can install the bottom at corresponding drawer more firmly, still including being used for each water collecting cover 21 and the mounting bracket 6 that the drawer bottom that corresponds is connected in this embodiment, this mounting bracket 6 sets up the both ends at each water conservancy diversion layer 2 respectively, and each mounting bracket 6 all includes along the installation horizontal pole 61 that extends with each water collecting cover 21 extending direction looks vertically, all be equipped with the spliced pole 62 with the water collecting cover 21 one-to-one of each water conservancy diversion layer 2 along its length direction interval on this installation horizontal pole 61, and each spliced pole 62 is fixed with the water catch bowl 210 that corresponds respectively, still be fixed with the equipment post 63 on the installation horizontal pole 61, this equipment post 63 is fixed with the bottom that corresponds the drawer.

In addition, the disinfection liner 1 is provided with two ultraviolet lamps 8, and the ultraviolet lamps 8 are arranged on the back plate of the disinfection liner 1 up and down in the embodiment. After the tableware to be disinfected is placed in each drawer, the gap between every two tableware is a dead angle for ultraviolet disinfection, so that in the embodiment, the exposed surface of each flow guide layer 2 is a reflecting surface, and the ultraviolet rays irradiated on the flow guide layer 2 can be reflected and focused by the reflecting surface on the outer surface of the flow guide layer 2, so that the irradiation range of the ultraviolet rays is enlarged, the irradiation intensity of the ultraviolet rays is enhanced, and the disinfection effect of the ultraviolet rays is enhanced. In this embodiment, the inner and outer surfaces of each water collecting cover 21 are reflective surfaces, and the surfaces of each flow guide control member 3 are also reflective surfaces.

Therefore, in the invention, the guide control member 3 is driven by the driving structure 5 to realize the back-and-forth swinging rotation of the guide control member 3, so that the opening and closing of the guide gap 22 can be realized, a certain wind field can be generated by the rotation to promote the drying of tableware, and a certain negative pressure can be generated by the rotation to promote the rising of hot air from bottom to top.
