[0039] The storage cabinet 4 of this embodiment is formed integrally on the cabinet 3. Specifically, a bottom plate 41 arranged near the bottom is provided on the right side of the installation area 30, and a vertical frame edge 42 extending upward to the countertop 31 is connected to the left end of the front edge of the bottom plate 41. The vertical frame edge 42, the bottom plate 41, the countertop 31, and the left side wall of the cabinet body 32 on the right side of the cabinet 3 together enclose the storage cabinet 4. The storage cabinet 4 with independent space can be used to accommodate the sink dishwasher 11, the water purifier 5 and the drainage assembly at the bottom of the sink dishwasher. When these components need to be repaired or maintained, only the front door panel of the storage cabinet needs to be opened, which is convenient for operation.
[0040] The vertical frame edge 42, the front edge of the bottom plate 41, the lower edge of the table top 31, and the left edge of the cabinet body 32 on the right side of the cabinet 3 together enclose a front opening of the storage cabinet 4. A door panel 43 is rotatably connected to the left edge of the cabinet body 32 on the right side of the cabinet 3 to open or close the front opening.
[0041] After assembly, the sink-type dishwasher 11 of this embodiment is accommodated in the storage cabinet 4, and a space for installing the water purifier 5 is reserved between the bottom of the sink-type dishwasher 11 and the inner bottom wall of the storage cabinet 4. The storage cabinet 4 is also provided with a drainage assembly 401 connected to the bottom of the sink-type dishwasher 11, and the drainage assembly 401 is arranged near the rear side of the storage cabinet 4. Arranging the drainage assembly 401 near the rear side of the storage cabinet 4 not only saves the front side space for installing the water purifier 5 and for the user to place other items, but also facilitates the connection of the drainage assembly with the downpipe 402 at the back of the cabinet 3.
[0042] The height of the water tank 12 is less than that of the water tank dishwasher 11, and an installation gap 201 is left between the bottom of the water tank 12 and the bottom of the second cleaning device 2. The drain port 121 at the bottom of the water tank 12 is connected to the drain assembly 401 through a bent pipe 122. With such a structure, the water tank 12 can be drained normally when the water tank 12 and the second cleaning device 2 below are installed very compactly, thereby saving assembly space.
[0043] The bent pipe 122 includes a horizontal portion a connected to the drain port 121 at the bottom of the sink 12 and a vertical portion b located in the storage cabinet 4 and arranged near the left side of the storage cabinet 4.
