Description

TECHNICAL FIELD

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

[0002] At present, the common dish washer in market generally includes a box body and a spraying device arranged in the box body, the spraying device is used for taking water at the bottom of the box body to a water spraying component and spraying to the washing cavity to flush dishes. The volume of the washing cavity of most dish washers is fixed and cannot be changed according to the quantity demand of the cleaning tableware. When the quantity of the tableware to be cleaned is small, the tableware is placed in the large washing cavity for cleaning, which not only affects the cleaning effect, but also causes waste of water resources.

[0003] In addition, for some dish washers with large capacity, users are used to placing tableware in the dish washer for storage after dish washing. In this case, if the tableware used for each meal is small, the stored tableware needs to be cleaned together when cleaning tableware next time, which also causes waste of water and electricity resources.

[0004] In view of the above problems, the utility model discloses a dish washer with the patent number CN202023348649.2 (the publication number CN215383808U), which comprises a box body with an inner cavity, a partition plate assembly arranged in the inner cavity of the box body for separating the inner cavity of the box body into an upper space and a lower space, a fixed plate horizontally arranged in the middle of the box body and connected with the inner wall of the box body, a movable plate movably arranged on the fixed plate for separating or connecting the upper space and the lower space with the fixed plate, a surrounding plate arranged on the lower wall surface of the fixed plate and forming a relatively independent installation bin with the inner wall of the box body, a driving member arranged in the installation bin, and a power output shaft connected with the movable plate through the surrounding plate.

[0005] When the quantity of the tableware to be cleaned is small, the movable plate of the partition plate assembly moves relative to the fixed plate to separate the upper space and the lower space, the upper space can be used for placing and storing the cleaned tableware, and the lower space can be separately sprayed and cleaned, which not only fully utilizes the space of the box body, but also is beneficial to saving energy such as water and electricity; when the quantity of the tableware to be cleaned is large, the movable plate of the partition plate assembly moves relative to the fixed plate to connect the upper space and the lower space, and the tableware in the upper space and the lower space is cleaned.

[0006] For this kind of side door dishwasher, when taking and placing the tableware on the lower rack, the lower rack is pulled forward to the door body so as to facilitate the user to take and place the tableware in the dishwasher. The rack is generally a hollow structure surrounded by several frame strips to be able to drain water. When the contaminated tableware is placed on the lower rack, the oil stains and sundries on the tableware may leak out of the rack, contaminating the door body. When the dishwasher is in half-cavity washing (i.e. only the lower space is sprayed for cleaning), the upper part of the contaminated door body cannot be cleaned, and the contamination of the upper part of the door body will affect the storage of the upper space, thereby failing to realize the half-cavity effect of upper storage and lower washing.

[0007] Not only the above-mentioned situation, even if the dishwasher without the partition assembly, if the user wants to store tableware in the dishwasher, the dirt on the door body will also affect the storage of the tableware. Utility model content

[0041] A partition assembly is arranged in the cabinet 1, and the partition assembly can divide the washing cavity into a relatively independent upper space 11 and a lower space 12. The partition assembly comprises a fixed plate and a movable plate 3. The fixed plate is horizontally arranged at the rear of the cabinet 1 and connected with the inner side wall of the cabinet 1. The movable plate 3 is arranged to be movable forward and backward relative to the fixed plate, and is used to cooperate with the fixed plate to separate or connect the upper space 11 and the lower space 12.

[0042] An upper basket and a lower basket 5 which can be pulled out forward and backward are arranged in the cabinet 1. The upper basket is arranged in the upper space 11, and the lower basket 5 is arranged in the lower space 12.

[0043] The above is the prior art, which will not be described here.

[0044] The part of the door body 2 corresponding to the upper space 11 and the lower space 12 in the closed state is respectively referred to as the upper part and the lower part of the door body 2. The upper part of the door body 2 is a part which is easy to be contaminated. The specific position of the part which is easy to be contaminated is as follows: in the state that the door body 2 is opened, the lower basket 5 is moved out of the cabinet 1 and rests on the door body 2, and the part of the upper part of the door body 2 which is covered by the lower basket 5 is the part which is easy to be contaminated.

[0045] A spraying member 6 is arranged on the partition assembly. The spraying member 6 is hollow inside, and the spraying member 6 is provided with spraying holes 61 which are connected with the inside of the spraying member 6.

The water inlet end of the water inlet channel 32 is connected with the connecting pipe 72 through a water guide pipe 73.

[0048] The water guide pipe 73 is a flexible pipe, such as a corrugated pipe. In this way, when the movable plate 3 moves, the water guide pipe 73 can be self-adaptively stretched and contracted.

[0049] In order to be able to control the water path of the water inlet channel 32 to be connected or disconnected according to needs, a valve for controlling the water path to be connected or disconnected is arranged on the water inlet channel 32 or the water guide pipe 73. The valve can adopt the existing electromagnetic valve structure.

[0050] In addition, the inner wall surface of the door body 2 is provided with an exhaust port 21, which is in fluid communication with the outside through an exhaust pipe. When the dishwasher is in the drying process, the humid hot airflow in the washing cavity needs to be discharged through the exhaust port 21 to improve the drying efficiency and ensure the balance of air pressure inside and outside the washing cavity. In order to prevent the dirt on the tableware from blocking the exhaust port 21, a blocking prevention piece 22 is arranged at the cover of the exhaust port 21. The blocking prevention piece 22 is located on the inner side of the exhaust port 21 and has a spacing therebetween to form an airflow passage. The exhaust port 21 is arranged at a position prone to contamination. Even if a small amount of dirt blocks the periphery of the exhaust port 21, the water sprayed by the spray piece 6 can also wash it away.

[0053] The upper bowl rack in the upper space 11 of the dishwasher stores clean dishes to be stored. The lower bowl rack 5 in the lower space 12 of the dishwasher is pulled out of the box body 1 and places the tableware with dirt to be washed. The tableware with dirt on the lower bowl rack 5 will have residual garbage falling on the position prone to contamination of the door body 2.

[0054] If the door body 2 is closed at this time for washing, the kitchen garbage on the door body 2 will enter the upper space 11 of the dishwasher. Under the action of hot water and steam of the dishwasher, the residual garbage will affect the clean dishes stored in the upper space 11 during the long cleaning and storage process, thereby affecting the user experience.

[0055] The spray piece 6 is arranged on the partition assembly of the embodiment. When the door body 2 is closed, the valve on the water guide pipe 73 is opened, the water supply is supplied, the water in the spray piece 6 is sprayed to wash the position prone to contamination of the door body 2, and the residual washing is washed down. After the washing is completed, the partition assembly is actuated to the state that the upper space 11 is separated from the lower space 12. The lower space 12 is used for washing tableware, and the upper space 11 is used for storing tableware.
