Preferably, the inner diameter of the sink 11 gradually decreases in the direction away from the bottom 1 of the inner pot, the mutual abutment between the sink 2 and the sink 11 becomes stronger and stronger, and the abutment effect of the sink 11 becomes better and better. Preferably, the diameter of the mounting hole is smaller than the maximum outer diameter of the top cover 22, so as to limit the top cover 22 inside the sink 11; prevent the sink 2 from being separated from the bottom of the sink 11, causing water to overflow to the bottom of the inner tank 1, causing damage to the components and base 3 of the electrical components and the like below the bottom 1 of the inner tank, or accumulating on the base 3 to produce odor or corrode the base 3. The bottom 1 of the inner tank is gradually inclined downward from the outer edge toward the sink 11, so as to facilitate the discharge of washing water from the bottom 1 of the inner tank into the sink 2, and no water will remain in the inner tank. A water guide rib is also provided above the bottom 1 of the inner tank to guide the water flow. The water guide rib is protruding from the bottom 1 of the inner tank, extending from the outer edge of the bottom 1 of the inner tank toward the mounting hole, and guiding the water flow to the sink 2 in the mounting hole.
