[0080] 5) The first hydraulic support 301 and the second hydraulic support 302 move downward, the connecting rod 30202 drives the bowl feeding flip plate 604 to reset, and the first hydraulic support 301 and the second hydraulic support 302 move downward while driving the bowl suction mechanism 303 to move downward and reset. At this time, the bowl suction mechanism 303 is aligned with the cleaning mechanism 403 of the pre-cleaning module 4;

[0081] 6) The first cylinder 404 drives the cleaning mechanism 403 to move forward, and the storage tank plug 40303 contacts the inner surface of the bowl and plate. At this time, the storage tank plug 40303 is pushed to move backward so that the outer curved surface of the frustum body 4030303 is separated from the inner curved surface of the frustum hole 4030102. When the inner surface of the bowl and plate touches the sensor 4030503, the forward movement stops, and the cleaning liquid enters the gap between the outer curved surface of the frustum body 4030303 and the inner curved surface of the frustum hole 4030102, and the cleaning liquid thus enters the cleaning liquid flow channel 4030502 of the arc scraper 40305. The rotating power device 40302 drives the cleaning mechanism 403 to rotate one circle to scrape off the large pieces of residual food in the bowl and plate. The cleaned residual food falls into the kitchen waste box 5. While the cleaning mechanism 403 rotates, the cleaning liquid flows out from the cleaning liquid outlet 4030501 and flows into the bowl and plate. , while pre-cleaning the dishes, the cleaning liquid wets the dishes. The chemical components in the cleaning liquid can effectively soften food residues and grease, making them easier to remove. During the pre-cleaning process, the cleaning liquid can remove most of the residues and loose stains on the surface of the dishes. After the initial cleaning, the subsequent cleaning procedures can be more efficient, reducing the overall cleaning time, extending the life of the dishwasher, and improving the hygiene standards of tableware. After one rotation, the rotating power device 40302 stops moving, and the first cylinder 404 drives the cleaning mechanism 403 to move backward for reset. The reset spring 40304 drives the storage tank plug 40303 to reset, so that the outer curved surface of the truncated cone body 4030303 is re-connected with the inner curved surface of the truncated cone hole 4030102, and the outer curved surface of the truncated cone body 4030303 blocks the arc scraper mounting hole 4030105, so that the cleaning liquid cannot enter the arc scraper 40305;

[0082] 7) The hydraulic transmission component 30308 drives the slider 30303 to move backward on the sliding shaft 30302. The slider 30303 drives the flip rod 30306 to flip 90° through the flip connecting rod 30305, thereby driving the suction head 30307 to flip 90°, so that the suction head 30307 moves to the bottom. At this time, the vacuum stops, and the dishes fall onto the washing and drying conveyor belt 101. The hydraulic transmission component 30308 drives the suction head 30307 to reset and perform the next round of action.

[0083] 8) The dishes enter the washing box 201 for fine washing, and the residual heat directly acts on the heat conducting rod 207 through the heat transfer groove 20101. The heat of the heat conducting rod 207 is transferred from the washing box 201 end to the drying box 205 end;

[0084] 9) The washed dishes enter the drying box 205, and the fan blows air into the drying box 205 through the square slot on the top of the drying box 205. The air passes through the heated heat conducting rod 207 and is blown out from the air outlet 20601 to dry the dishes;

[0085] 10) The dried dishes are taken out from the drying box 205 and stored.

[0086] The implementation methods of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
