[0050] Please refer to Figures 3 to 14 It is different from Embodiment 1 in that: it further includes a second tableware rack 3 and a second door portion 4. A second opening is provided on the second side wall of the housing, and the second door portion 4 and the second opening cooperate to be able to close the second opening; the second tableware rack 3 can move relative to the housing, and by moving, the second tableware rack 3 can change between the second cleaning state located inside the housing and the second placing and taking state at least partially located outside the housing. The second tableware rack 3 moves between the second cleaning state and the second placing and taking state through the second opening; the cleaning mechanism also cooperates with the second tableware rack 3 to be able to clean the tableware placed on the second tableware rack 3 in the second cleaning state. Among them, the second tableware rack 3 is slidably and movably connected to the housing, and the sliding direction corresponds to the direction of entry and exit of the second opening. In this embodiment, two openings are designed, and the two tableware racks move relative to the openings respectively. One opening is provided on the side wall and can cooperate with the sink to facilitate the placement of some tableware such as rice bowls, soup bowls, chopsticks, spoons, etc., and the other opening is provided on the front wall to facilitate the placement or removal of some tableware such as large tableware (such as large pots and large soup basins) to be able to facilitate the removal or entry of the first sub-rack (specifically described below).

[0051] Please refer to Figure 3 and Figure 4, the second tableware rack 3 includes a first sub-rack 31 and a second sub-rack 32. The first sub-rack 31 is like a plate rack, and the plate rack is used for placing plates. Generally, a single plate rack can accommodate multiple plates C2; the second sub-rack 32 is like a large-item rack, and the large-item rack is used for placing large pots and large soup basins. In this embodiment, the first sub-rack 31 and the second sub-rack 32 are arranged inside and outside, with the plate rack on the outside and the large-item rack on the inside, which is convenient for use. A second locking mechanism is provided between the first sub-rack 31 and the second sub-rack 32 to lock or release the above-mentioned locking. The second locking mechanism includes a connecting ring 33 and a convex column 34. The connecting ring 33 includes a ring body 331 and a connecting rod 332 fixed to the ring body. The end of the connecting rod is fixedly connected or rotatably connected to the first sub-rack 31, and the convex column 34 is fixed to the second sub-rack 32. Then, by sleeving the ring body 331 of the connecting ring 33 on the convex column 34, the first sub-rack 31 and the second sub-rack 32 can be locked together, and the ring body 331 can be taken out of the convex column 34 to unlock the above-mentioned locking. The second locking mechanism restricts the lateral displacement and misalignment of the two sub-racks, which is suitable for placing large tableware, avoids tableware from falling, and facilitates pushing the second tableware rack as a whole into the inner cavity of the shell. Roller mechanisms 35 are provided under both the first sub-rack 31 and the second sub-rack 32. At least one of the four roller mechanisms 35 under the first sub-rack 31 is provided with a wheel buckle 351. On the one hand, it is convenient to pull out and push in the second tableware rack. On the other hand, with the wheel buckle 351, the rollers can be locked after locking and the second tableware rack can be pulled out after unlocking. Further, the first sub-rack 31 can be disassembled and assembled relative to the shell. During use, the first sub-rack can be taken out of the shell and directly placed at the position where it is needed, such as a kitchen counter or a tabletop, etc. The plate rack is placed on the kitchen counter to facilitate the user's use. At this time, the wheel buckle can lock the roller structure to prevent the roller mechanism from moving.

[0052] A stain-blocking part 5 is connected to the second tableware rack 3. The stain-blocking part 5 is movably connected to the first sub-rack 31 and can move relative to the first sub-rack 31 between a stain-storing position and a shielding position. The stain-storing position is directly below the first sub-rack 31 to store the stains dripping from the plates on the first sub-rack 31. The shielding position is an area away from directly below the first sub-rack 31 to avoid blocking the cleaning of the tableware on the second tableware rack by the cleaning mechanism. The stain-blocking part 5 includes a stain-blocking plate 51 and a connecting frame 52 fixed to the stain-blocking plate 51. The end of the connecting frame 52 can be swingably connected to the first sub-rack 31 so that the stain-blocking part 5 can swing relative to the first sub-rack 31. An upwardly concave cavity is formed on the stain-blocking plate 51 to store the dripping stains. The movement of the stain-blocking part 5 and the movement of the second tableware rack 3 are interlocked. The second cleaning state and the second picking and placing state of the second tableware rack 3 respectively correspond to the shielding position and the stain-storing position of the stain-blocking part 5. The specific structure of the interlock is as follows: An interlocking part 53 is fixed in the housing. The interlocking part 53 cooperates with the stain-blocking plate 51. When the second tableware rack 3 slides inward, the stain-blocking plate 51 is pushed by the interlocking part 53 so that the stain-blocking part 5 swings upward to the shielding position. When pulled outwards, under the action of the gravity of the stain-blocking part 5, the stain-blocking part 5 swings downward to the stain-storing position. In general use, the user does not need to manually adjust the stain-blocking part 5. The stain-blocking part 5 can not only store the dripping oil stains in the stain-storing position to avoid polluting the ground, but also avoid blocking the cleaning by the cleaning equipment in the shielding position and avoid storing cleaning water on the stain-blocking part 5.

[0053] The cleaning mechanism 6 includes a spray arm 61 that can be rotatably connected in the housing. Spray nozzles are provided on the spray arm 61, and water flows out from the spray nozzles of the spray arm 61. On the one hand, the cleaning range is expanded by the rotation of the spray arm 61 to clean the tableware on the tableware rack. On the other hand, high-pressure water can be sprayed from the spray nozzles to clean the tableware on the tableware rack cleanly. The cleaning mechanism 6 heats the water to 60 or 70 degrees and mixes it with a special dishwashing agent, and sprays the high-pressure water around through one or two rotating spray arms to achieve the function of dishwashing, and it can refer to the prior art.

[0054] In this embodiment, the height of the second opening cooperates with the first tableware rack and the second tableware rack so that the entire interior of the housing, including the above-mentioned first tableware rack and the second tableware rack, can be seen after opening the second door part, which is convenient for observation and maintenance and for reaching in to adjust the tableware on the first tableware rack when necessary. According to needs, the first tableware rack can also be pulled out relative to the second opening. Embodiment III

[0055] Please refer to Figure 15 and Figure 16, the difference between it and the first and second embodiments lies in that: a second locking mechanism is provided between the second tableware rack 3 and the oil stain blocking part 5, and the oil stain blocking part is kept at the oil stain receiving position through the second locking mechanism. The second locking structure includes a limiting part and a magnetic attraction mechanism. A hook 521 is provided at the end of the connecting frame 52. The central angle of the hook 521 is, for example, 270 degrees. The hook 521 is hooked on a connecting beam 311 at the bottom of the first sub-rack to achieve a swing connection. The limiting part is a protrusion 71 fixedly protruding from the connecting beam 311, and the protrusion 71 is located between the openings of the hook 521. The protrusion 71 and the connecting frame 52 cooperate to limit the position at the oil stain receiving position or the anti-blocking position, playing a role of stability and limitation. The magnetic attraction mechanism includes two first and second parts that can magnetically attract each other. The first and second parts are respectively fixed on the protrusion and the connecting frame 52. When moving to the oil stain receiving position, the connecting frame and the protrusion are magnetically attracted together, so that the oil stain blocking part is firmly attracted at the position directly below vertically, continuously waiting to receive the oil stain from above, preventing the oil stain blocking part from moving, improving the oil stain blocking effect, and the magnetic attraction will not affect the normal upward swing of the oil stain blocking part. Embodiment 4

[0056] Please refer to Figure 17 , the difference between it and the third embodiment lies in that: a hanging ring 522 is provided at the end of the connecting frame 52, and the hanging ring 522 is sleeved on the connecting beam 311; the limiting part is a U-shaped frame 72 fixedly protruding under the first sub-rack. The U-shaped frame includes two first fixing rods fixed on the connecting beam 311 and a second fixing rod fixedly connected to the two first fixing rods. The second fixing rod and the connecting frame 52 cooperate to limit the position at the oil stain receiving position. The magnetic attraction mechanism includes two first and second parts that can magnetically attract each other. The first and second parts are respectively fixed on the second fixing rod and the connecting frame 52.

[0057] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
