Description

TECHNICAL FIELD

[0001] The utility model relates to a dish washer. BACKGROUND

[0002] At present, the dish washer with the partition plate assembly is composed of the fixed plate and the moving plate, such as the utility model patent (CN202222590516.9) (CN218852654U) disclosed by the Chinese utility model patent, when the cavity washing is not needed, the moving plate is hidden below the fixed plate, even in the state of the partition plate assembly being collected, the cavity space is also occupied, and the driving mechanism is exposed, which is not beautiful, and the tableware may interfere with the driving part, resulting in the telescopic failure of the moving plate. In addition, in order to speed up the water return (in the cleaning process, the water sprayed on the partition plate is quickly returned to the bottom of the cavity, so that the spray arm has enough water supply), the moving plate is made into a circular arc surface, but the plastic part is easy to deform, it is difficult to achieve the ideal design size, and the production requirement is high. If the moving plate deforms, it is easy to appear stuck in the telescopic process and report errors. Finally, the existing partition plate assembly has many parts and assembly processes, and the production efficiency is low.

[0003] In view of the above problems, the utility model patent (CN202021358357.4) (CN213216789U) discloses a cleaning machine, which comprises a box body and a first spraying device arranged at the lower part of the box body. The box body is also provided with a partition plate assembly which can separate the box body into an upper space and a lower space. The partition plate assembly comprises a reel and a flexible partition plate. The reel is rotatably arranged on the rear side wall of the box body. The flexible partition plate is wound on the reel and the extended end of the reel is movably constrained on the inner side wall of the box body and separates or connects the upper space and the lower space. When the number of tableware to be cleaned is small, the flexible partition plate is extended from the reel and pulled forward to separate the upper space and the lower space, and at this time, half-cavity cleaning is carried out. The upper space can be used to place the cleaned tableware, and the lower space can be independently sprayed and cleaned, which fully utilizes the space of the box body and saves water and electricity and other energy sources. When the number of tableware to be cleaned is large, the reel is rotated to wind and recover the flexible partition plate, so that the upper space and the lower space are connected, and at this time, full-cavity cleaning is carried out, and the tableware in the upper space and the lower space is cleaned at the same time.

[0004] The structure of the flexible partition plate makes the space occupied by the partition plate assembly smaller when half-cavity cleaning is carried out, and compared with the structure of the partition plate assembly comprising the moving plate and the fixed plate, the driving mechanism for driving the moving plate to move is not needed, but the patent needs to design the driving mechanism and the pull rope assembly to drive the partition plate assembly to move, and the structure is still relatively complex.

[0005] In addition, because the flexible partition plate needs to be able to be wound, the thickness of the flexible partition plate is generally thin, and the sealing performance of the partition plate can be poor, so that water can leak from the upper space and the lower space during half-cavity washing, and the effect of half-cavity washing is affected.

The partitions 4 can be wound on the rotating shafts 3 one by one, and of course, the partitions 4 and the rotating shafts 3 can also be more than two. In the state that the partitions 4 are in the second position, at least two of the partitions 4 are arranged in sequence in the up-down direction to form a partition unit with a certain thickness, and the adjacent two partitions 4 are arranged at intervals to form a cavity therebetween, further improving the sealing performance of the partition assembly and preventing water from seeping from the lower space 12 into the upper space 11 when half-cavity washing.

[0038] The other ends of all the partitions 4 are connected through the blocking strip 5. In the state that the partitions 4 are in the first position, the partitions 4 are wound on the rotating shaft 3 to form a winding part, and the blocking strip 5 is located at the front side of the winding part. The blocking strip 5 relatively fixes the two partitions 4 and enables them to move synchronously.

[0039] In the state that the door body is closed and the partitions 4 are in the second position, the blocking strip 5 abuts against the rear wall surface of the door body, and the front part of the blocking strip 5 is a sealing part 51 to ensure the sealing performance between the blocking strip 5 and the door body and prevent water from leaking between the upper space 11 and the lower space 12.
