[0037] By setting the auxiliary door 20 of the door washing mechanism to a slidable structure, the user can open and close the delivery port 12 by sliding, thereby ensuring the convenience of operation of the auxiliary door 20. Since the auxiliary door 20 slides at the delivery port 12, the auxiliary door 20 is prevented from opening in a rotating manner and occupying a large space. In addition, the sliding auxiliary door 20 has a simple structure and is easy to process and manufacture, which is conducive to reducing the difficulty of processing and manufacturing the door washing mechanism.

[0038] like Figures 2 to 4 As shown, the door structure 10 has a limiting groove 13, and the auxiliary door 20 has an avoidance position and a shielding position. When the auxiliary door 20 slides into the limiting groove 13 to avoid the delivery port 12, it is in the avoidance position; when at least a part of the auxiliary door 20 slides out of the limiting groove 13 to shield the delivery port 12, it is in the shielding position. In this way, the limiting groove 13 plays a role in storing and limiting the auxiliary door 20.

[0039] like Figures 2 to 8 As shown, the door structure 10 includes a panel 14, a loading port 12 is provided on the panel 14, and a limiting groove 13 is located on the side of the panel 14 facing the door washing cavity 11. In this way, the limiting groove 13 is hidden inside the panel 14, which ensures the aesthetic appearance of the panel 14 and fully utilizes the internal space of the door structure 10.

[0040] like Figures 4 to 8As shown, the door structure 10 further includes a bowl 15 and a partition 16, wherein the bowl 15 is connected to the partition 16 and encloses a door washing chamber 11, and the panel 14 is connected to the partition 16 and is located on the side of the partition 16 away from the door washing chamber 11; wherein, a limiting rib 141 is protrudingly provided on the surface of the panel 14 facing the partition 16, the limiting rib 141 extends around the outer periphery of the auxiliary door 20 to form a U-shaped structure, and an opening is formed at the mouth of the U-shaped structure for the auxiliary door 20 to slide in and out, and a limiting groove 13 is formed between the limiting rib 141 and the panel 14. In this way, it is ensured that the limiting rib 141 can effectively limit the auxiliary door 20, so that the auxiliary door 20 slides along the limiting groove 13 in a preset direction and preset stroke.

[0041] like Figure 4 and Figure 5 As shown, the door structure 10 further includes a decorative ring 142 and a door inner shell 151 .

The surface of the limiting boss 21 facing the door washing chamber 11 is partially recessed to form a limiting hole 211. A telescopic lock 162 is provided at a position opposite to the limiting hole 211 of the partition 16. When the auxiliary door 20 closes the delivery port 12, the telescopic lock 162 extends into the limiting hole 211 to lock the auxiliary door 20. In this way, the provision of the telescopic lock 162 ensures the reliable connection between the auxiliary door 20 and the door structure 10.

[0049] Optionally, the door washing mechanism further includes a travel switch and a controller, wherein the travel switch is arranged between the panel 14 and the partition 16, and the travel switch detects whether the auxiliary door 20 is fully closed; the controller controls the extension of the telescopic lock 162 according to the travel switch detecting that the auxiliary door 20 is fully closed. In this way, it is ensured that the telescopic lock 162 is extended only when the travel switch detects that the auxiliary door 20 is fully closed. On the one hand, it is ensured that the auxiliary door 20 is smoothly closed in place, and the telescopic lock 162 is prevented from being extended by mistake during the sliding process of the auxiliary door 20 and blocking the normal sliding of the auxiliary door 20; on the other hand, it is ensured that the telescopic lock 162 extends into the limiting hole 211 after the auxiliary door 20 is fully closed, thereby locking the auxiliary door 20.
