As shown in fig. 4, the aforementioned drying mechanism 7 has two hot air outlets 71 arranged at opposite intervals, and each hot air outlet 71 corresponds to one hot air duct 8. The two hot air pipes 8 are arranged opposite to each other and are respectively arranged on the left and right inner side walls of the washing chamber 101. The two hot air pipes 8 have the same structure, and one of the hot air pipes 8 will be described as an example.

during cleaning, a part of cleaning water is guided into the water inlet channel 20 by the impeller assembly 62 under the action of the water pumping mechanism 6 and finally enters the flow channel 21, and the water flow applies thrust to the side wall of the flow channel 21, so that the spraying piece 2 rotates and the water flow is sprayed out from the spraying holes 211 on the upper side. Due to the inclined arrangement of the top wall plate 2a of the spraying member 2 and the 120-degree distributed guide ribs 23, residues are not easy to adhere to the upper surface of the top wall plate of the spraying member 2 in the rotating process, and are more easy to be thrown into the residue collecting chamber 30 of the residue collecting box 3 through the opening 301.

When the cleaning is finished and the drying mode is entered, a fan of a drying mechanism integrated in the door body is started to blow, drying air flows are led to be discharged through a hot air outlet 71 along the built-in air guide, hot air discharged through the hot air outlet 71 enters an air outlet 8111 on a hot air pipe 8 on the corresponding side to be discharged, and the hot air pipes 8 are arranged in a continuous S shape and the two hot air pipes 8 are arranged oppositely, so that the bidirectional convection drying effect on different height layers in the washing chamber is realized. In addition, part of hot air (drying air flow) in the hot air pipe 8 enters the inner cavity 40 of the annular pipe 4 and sprays the discharge hole 401, so that 360-degree full-coverage drying blowing on the bottom of the washing chamber is realized, and the bottom drying effect is improved.

In addition, in the drying process, the motor 61 starts to work, when the output shaft moves upwards to the power of the motor 61 is greatly suddenly changed, at this time, the clamping part at the top of the impeller assembly 62 is clamped with the convex part, at this time, the output shaft of the motor 61 stops moving upwards, the spraying member 2 is driven to rotate when the motor 61 continues to work, the spraying member 2 continuously throws out water on the top wall plate 2a in the rotating process, and meanwhile, the air deflector 24 of the spraying member 2 drives the drying air flow sprayed out through the discharge hole 401 of the annular pipe 4 to rotate and flow in the rotating process, so that the air flow in the draining cavity 102 is accelerated, and the drying effect on the accommodating cavity 10 of the cleaning box 1 is improved.
