In this way, the fan 6 discharges the hot air in the air guide channel 7 into the chamber 10 through the air guide channel 111, so as to dry the inside of the chamber 10.

The disassembly and assembly process of the door body and the box body is as follows:

when the door body and the box body 1 need to be assembled together, firstly, the two damping shafts 4 are assembled on the door body 2, then the damping shafts 4 and the connecting seats 32 are fixed together through screws, and secondly, the mounting seats 31, the gaskets and the reinforcing plates are connected and fixed on the groove body through bolts and nuts. The connecting shaft 33 is rotated to an 'on' position (a first state), then the connecting seat 32 is aligned with the mounting seat 31, the door body 2 is moved downwards, the convex part 313 of the convex column 312 is inserted into the first opening 331 of the connecting shaft 33, at the moment, the connecting shaft 33 is rotated to an 'off' position (a second state), the convex part 313 of the convex column 312 is arranged corresponding to the second opening 332, at the moment, the convex part 313 is limited in the cavity 330 of the connecting shaft 33, namely, the connecting shaft 33 locks the convex column 312, and the door body 2 is assembled with the box body 1. During the whole attaching process, the electric wire 51 is always in the contracted state, and the electric wire 51 is gathered in the reel 5. When the door body 2 and the box body 1 are assembled together, the dishwasher normally works, the electric wire 51 is folded into the reel 5 by the winding wire and is hidden in the storage box, and the inner space of the chamber is not occupied. And no safety accident is caused.

When the door body 2 needs to be separated from the box body 1, the connecting shaft 33 is rotated to the opening position, then the door body 2 is moved upwards, the connecting seat 32 is driven to move upwards, and at the moment, the convex part 313 of the convex column 312 is separated from the first opening 331, namely, the door body 2 is separated from the box body 1. At this time, the electric wire 51 is in a stretched state, and the electric wire 51 in the reel 5 is released. Therefore, the electric wire is not pulled to be broken when the door body is in a disassembly state, and the signal transmission is normal.
