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

[0031] As Figures 1 to 4 shown, the dish washing machine of the preferred embodiment comprises a box body 1, a door body 2, a partition assembly, an upper dish rack 4, a lower dish rack 5 and a spraying part 6.

[0032] The front side of the box body 1 is open, and the door body 2 is movably arranged at the front side opening of the box body 1, so as to open or close the front side opening of the box body 1. In the state that the door body 2 is closed, the door body 2 and the box body 1 enclose a washing cavity. Specifically, the bottom of the door body 2 is rotatably connected to the box body 1, and the upper part of the door body 2 can be deflected forward and backward relative to the box body 1, so as to open or close the open end of the box body 1.

[0033] The partition assembly is arranged in the box body 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 moving plate 3. The fixed plate is horizontally arranged at the rear part of the box body 1 and connected to the inner side wall of the box body 1. The moving 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.

[0034] The box body 1 is provided with the upper dish rack 4 and the lower dish rack 5 which can be pulled forward and backward. The upper dish rack 4 is located in the upper space 11, and the lower dish rack 5 is located in the lower space 12.

[0035] The above is the prior art, which will not be described here.

[0036] In the state that the door body 2 is opened, the lower dish rack 5 is placed on the door body 2, and the part of the upper part of the door body 2 covered by the lower dish rack 5 is a part prone to contamination. The spraying part 6 is arranged on the front side wall of the upper dish rack 4. The spraying part 6 is hollow inside. The spraying part 6 is provided with spraying holes 61 which are connected to the inside of the spraying part 6. In the state that the door body 2 is closed, the part prone to contamination of the door body 2 is located on the spraying path of the spraying holes 61. Of course, the spraying holes 61 can also be directed to other areas of the door body 2. In this case, the spraying part is not limited to being arranged on the upper dish rack 4, but can also be arranged on the lower dish rack 5.

[0037] In order to increase the spraying range, the spraying holes 61 are tapered in the direction of water flow, and in order to increase the diffusion angle of water to the circumference of the spraying holes 61, vertical extending ribs 62 are arranged in the spraying holes 61, so as to divide the spraying holes 61 into spraying openings arranged in sequence in the left and right directions.

[0038] The upper bowl rack 4 is a hollow structure composed of multiple frame strips 41. The spray component 6 has an open-bottomed groove 63, and the top frame strip 41 of the upper bowl rack 4 is embedded in the groove 63 of the spray component 6.

[0039] Because of the location of the sprayer 6, it can not only spray water, but also be used as a handle to facilitate pushing and pulling the dish rack 4, making it a multi-purpose item.

[0040] In order to supply water to the spray unit 6, a water supply pipe 7 is provided in the housing 1, and the spray unit 6 and the water supply pipe 7 are connected by a connecting pipe 8.

[0041] The water supply pipe 7 is located at the rear of the box 1. One of the frame strips 41 of the upper bowl rack 4 is partially hollow to serve as a connecting pipe 8. In this way, the connecting pipe 8 can also serve as a frame, which can constrain and position the tableware in the upper bowl rack 4.

[0042] The cleaning logic for the easily soiled parts of the dishwasher in this embodiment is as follows:

[0043] Clean dishes are placed in the upper rack 4 of the upper space 11 of the dishwasher, and the lower rack 5 of the lower space 12 is pulled out of the cabinet 1 to place dirty dishes that need to be washed. Residual garbage from the dirty dishes in the lower rack 5 will drip onto the easily contaminated parts of the door 2.

[0044] If the door 2 is closed for washing at this time, the food waste on the door 2 will enter the upper space 11 of the dishwasher. Under the action of hot water and steam in the dishwasher, during the long-term cleaning and storage process, the residual waste will affect the clean dishes stored in the upper space 11, thus affecting the user experience.

[0045] In this embodiment, a spray element 6 is provided on the upper dish rack 4. When the door 2 is closed, the valve on the water pipe is opened, water is supplied, and the water in the spray element 6 sprays out to rinse the easily contaminated parts of the door 2, washing away the residue. After rinsing, the partition assembly moves to a state where the upper space 11 and the lower space 12 are separated. The lower space 12 is used for washing tableware, and the upper space 11 is used for storing tableware.

[0046] The door body 2 is usually equipped with exhaust vents, detergent dispensing devices, etc. The exhaust vents and detergent dispensing devices are usually located in areas prone to contamination. If they are blocked or contaminated, their working effect will be affected.

[0047] The inner wall of the door 2 is provided with an exhaust vent, which is connected to the outside environment through an exhaust pipe. When the dishwasher is in the drying process, the hot and humid air in the washing chamber needs to be discharged through the exhaust vent to improve drying efficiency and ensure the balance of air pressure inside and outside the washing chamber. The exhaust vent is located in a part that is prone to contamination, so even if a small amount of dirt is blocked around the exhaust vent, it will be washed away by the water sprayed by the spray nozzle 6. The structure of the exhaust vent can be referred to in Chinese Utility Model Patent Application No. CN202321317157.8 (Publication No. CN220293571U), entitled "Structure of Door 2 for Dishwasher and Dishwasher".
