The air supply assembly 2 is hollow inside to form an air collecting chamber 124 connected to the air hole 123, and the air outlet end of the air supply assembly 4 is connected to the air collecting chamber 124.

[0028] The blowing assembly 2 of this embodiment includes an air collecting box 21, which is a flat rectangular parallelepiped. When the air collecting box 21 is located in the accommodating groove 120, the outer wall of the air collecting box 21 is kept flush with the corresponding inner wall of the box body 1, and the blowing hole 211 is opened on the outer wall of the air collecting box 21. With the above structure, the whole inside of the washing chamber remains unchanged, the washing space is not affected, and the air collecting box can be protected.

[0029] The outer wall of the air collecting box 21 is also provided with an ultraviolet lamp 22 that can sterilize the washing cavity and the tableware therein, and can sterilize and disinfect the tableware to improve the cleanliness of the tableware. The bottom of the air collecting box 21 is provided with an opening 214 arranged near its second end, and a mounting tube 215 is connected below the opening 214. The lower end of the mounting tube 215 passes through the bottom of the accommodating groove 120 and is located outside the box body 1. The mounting tube 215 is provided with a power cord 216 for supplying power to the ultraviolet lamp 22. The above structure is adopted, and it is convenient to supply power to the ultraviolet lamp 22 without affecting the upward and downward movement of the air collecting box 21.

[0030] The bottom of the air collecting box 21 is provided with an air inlet 212 arranged near the first end thereof, and a telescopic tube 213 is connected below the air inlet 212, and the lower end of the telescopic tube 213 passes through the bottom of the accommodating groove 120 and is connected to the air supply mechanism outside the box body 1. The bottom of the air collecting box 21 is provided with a drainage hole 217 for draining the accumulated water therein, so as to keep the air collecting box 21 dry without residual water.

[0031] The air outlet 123 is located on the second side wall 122 of the box body 1 and is arranged opposite to the blowing assembly 2 located on the first side wall 121. The second side wall 122 of the box body 1 gradually arches outward from the edge to the air outlet 123 to form a guide surface 125 for guiding the incoming wind to flow slowly. The above structure can effectively reduce the air flow turbulence caused by the vertical collision between the external exhaust flow and the side wall of the tank body, so that the external exhaust flow can flow smoothly along the side wall.

[0032] The air outlet 123 is arranged near the upper part of the second side wall 122 of the box body 1, and the slope of the guide surface above the air outlet 123 is greater than the slope of the guide surface below the air outlet. This structure cooperates with the lifting and lowering of the air collecting box 21 and the rotation of the baffle 23 as required, which is conducive to improving the drying efficiency and drying effect.

[0033] The air supply assembly 4 includes an air duct 41 and a fan 42. The first end of the air duct 41 is connected to the air outlet 123. The air duct 41 bypasses the second side wall 122 of the box body 1, the bottom of the box body, and extends upward along the first side wall 121 of the box body 1. The second end passes through the bottom of the accommodating groove 120 and is connected to the blowing assembly 2. The fan 42 is arranged in the air duct 21 and is used to provide power for forming an internal circulation of wind.

The above-mentioned multi-section air duct structure can fully condense the humid hot air and convert it into dry hot air, thereby improving the drying efficiency.

[0035] The fan 42 is disposed in the third section 413 and is arranged near the bottom of the box. A heating element 43 for heating the air is also disposed in the third section 413, and the heating element 43 is disposed below the fan 42. Further heating of the residual hot air after the condensed water is removed is beneficial to improving the drying efficiency and effect.

[0036] The local width of the second section 412 is increased to form a condensation chamber 410, in which a plurality of staggered condensation baffles 416 are arranged. Each condensation baffle 416 is tilted and arranged at intervals in the condensation chamber 410 to form a condensation channel with a louver structure. This structure is conducive to improving the removal effect of water vapor in the humid hot air.

[0037] The bottom wall of the fourth section 414 is provided with an overflow hole 417 for draining condensed water, and at least the bottom of the fourth section 414 located on both sides of the overflow hole 417 gradually slopes downward toward the overflow hole 417 to form a water guide surface 418.
