Description

Technical Field

[0001] This utility model relates to a dishwasher. Background Technology

[0002] Currently, most dishwashers on the market generally consist of a cabinet and a spray system located within the cabinet. The spray system draws water from the bottom of the cabinet into a spray nozzle and sprays it into the washing chamber to rinse the dishes. The washing chamber volume of most dishwashers is fixed and cannot be adjusted according to the amount of dishes to be washed. When the number of dishes to be washed is small, placing them in a large washing chamber not only affects the washing effect but also wastes water.

[0003] In addition, for some large-capacity dishwashers, users are used to storing the dishes inside the dishwasher after washing. In this case, if the number of dishes used per meal is small, the stored dishes need to be washed together with the dishes the next time, which will also waste water and electricity.

[0004] To address the aforementioned issues, Chinese utility model patent CN202023348649.2 (publication number CN215383808U) discloses a dishwasher, comprising: a cabinet having an inner cavity; a partition assembly disposed within the inner cavity of the cabinet for dividing the inner cavity into relatively independent upper and lower spaces; the partition assembly includes: a fixed plate, horizontally positioned in the middle of the cabinet and connected to the inner side wall of the cabinet; a movable plate movably disposed on the fixed plate for cooperating with the fixed plate to separate or connect the upper and lower spaces; further comprising: a surrounding plate disposed on the lower wall of the fixed plate, forming a relatively independent mounting compartment between the surrounding plate and the inner wall of the cabinet; and a drive component disposed in the mounting compartment, with a power output shaft passing through the surrounding plate and connected to the movable plate.

[0005] When the number of dishes to be washed is small, the movable plate of the partition assembly moves relative to the fixed plate to separate the upper and lower spaces. The upper space can be used to store the washed dishes, while the lower space can be sprayed and washed separately. This not only makes full use of the cabinet space but also helps to save energy such as water and electricity. When the number of dishes to be washed is large, the movable plate of the partition assembly moves relative to the fixed plate to connect the upper and lower spaces, and the dishes in the upper and lower spaces are washed at the same time.

[0006] For side-opening dishwashers, when removing dishes from the lower rack, the rack is pulled forward onto the door for easy access. The racks are typically perforated with several frame strips to allow water to drain. When soiled dishes are placed on the lower rack, grease and debris may leak out, contaminating the door. During a partial wash cycle (spraying only the lower section), the contaminated upper part of the door remains uncleaned. This contamination affects storage space in the upper section, preventing the proper separation of upper and lower sections for cleaning.

[0007] Not only in the above situations, but even in dishwashers without partitions, dirt on the door can affect the storage of dishes if the user wants to store them in the dishwasher. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a dishwasher that prevents the door from being contaminated and affecting the storage of tableware, in light of the current state of the technology.

[0009] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0010] A dishwasher, including

[0011] The box-shaped structure has an open front.

[0012] The door is movably disposed at the front opening of the cabinet, thereby opening or closing the front opening of the cabinet. When the door is closed, the door and the cabinet form a washing chamber.

[0013] Its characteristic is that it also includes

[0014] A spray element is provided on the door body. The spray element has spray holes, which face the inner wall surface of the door body when the door body is closed.

[0015] Preferably, with the door closed, the spray nozzles are directed towards the easily contaminated parts of the door, thus cleaning the dirt on the door in a targeted manner.

[0016] In the above solution, the cabinet is equipped with a partition assembly, which can divide the washing chamber into relatively independent upper and lower spaces to accommodate full-cavity washing and half-cavity washing modes. Generally, tableware is stored in the upper space and washed in the lower space. Therefore, the parts of the door corresponding to the upper and lower spaces when the door is closed are referred to as the upper and lower parts of the door, respectively. The easily contaminated part is located in the upper part of the door.

[0017] In the above solution, the door is equipped with a detergent dispensing device and / or an exhaust vent, and the detergent dispensing device and / or exhaust vent are located in areas prone to contamination.

[0018] Preferably, the spray element is located inside the door body, and the inner wall of the door body has spray holes that communicate with the spray nozzles. The spray holes are located at the top of the easily contaminated parts of the door body and face downwards. In this way, the spray element is hidden in the door body and does not occupy space in the washing chamber.

[0019] To increase the spray area, the spray holes are tapered with a gradually expanding diameter along the water flow direction.

[0020] To prevent water leakage between the spray nozzle and the door, a sealing gasket is provided between the spray nozzle and the door, and the sealing gasket has through holes that correspond one-to-one with the spray holes.

[0021] Preferably, the spray element is a strip extending in the left-right direction, and there are multiple spray holes spaced apart along the length of the spray element, with each spray hole and through hole corresponding to the other. This allows for multi-point spraying and a wide spray range.

[0022] To supply water to the spray unit, a water cup for storing water is provided at the bottom of the housing, and the spray unit is connected to the water cup via a water pipe. The water cup already present in the dishwasher is used to supply water to the spray unit.

[0023] To prevent the water pipe from interfering with the opening and closing of the door, the water pipe is a flexible hose that can be bent, and the door has a perforation near its bottom to allow the water pipe to pass through. The hose can adaptively expand and contract when the door is opened and closed, and the hose can be made of corrugated pipe; the perforation provides a certain guiding function for the hose, preventing the water pipe from being caught during the opening and closing of the door and affecting the water flow.

[0024] Preferably, the water pipe is provided with a valve at its inlet end that can open or close the inlet end. This allows the valve to be opened or closed depending on whether the easily contaminated parts of the door need to be cleaned. The valve can be an existing valve such as a solenoid valve.

[0025] Preferably, the door body is provided with a positioning element for positioning the water pipe at a position near the spray hole, so that the water pipe can be reliably connected to the spray element. The positioning element can be in the form of a snap fastener, such as a C-shaped cross-section, so that the water pipe can pass through the notch of the snap fastener.

[0026] In the above solution, the box is equipped with an upper bowl rack and a lower bowl rack that can be pulled out in the front and back. The upper bowl rack is located in the upper space and the lower bowl rack is located in the lower space.

[0027] The bottom of the door is rotatably connected to the box, and the upper part of the door can be tilted back and forth relative to the box, thereby opening or closing the open end of the box. When the door is open, the lower dish rack is placed on the door, and the part of the upper part of the door covered by the lower dish rack is the part that is easily contaminated.

[0028] Compared with the prior art, the advantages of this utility model are: by setting up a spraying component, if there is dirt on the door when the door is closed, the spraying component can spray water towards the door to clean it, so that the door will not contaminate the tableware stored in the cabinet.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] like Figures 1-7 As shown, the dishwasher of this preferred embodiment includes a cabinet 1, a door 2, a partition assembly, an upper dish rack 4, a lower dish rack 5, and a spray unit 6.

[0038] The front of the cabinet 1 is open, and the door 2 is movably disposed at the front opening of the cabinet 1, thereby opening or closing the front opening of the cabinet 1. When the door 2 is closed, the door 2 and the cabinet 1 form a washing chamber. Specifically, the bottom of the door 2 is rotatably connected to the cabinet 1, and the upper part of the door 2 can be tilted back and forth relative to the cabinet 1, thereby opening or closing the open end of the cabinet 1.

[0039] The partition assembly is located in the housing 1. The partition assembly can divide the washing chamber into a relatively independent upper space 11 and a lower space 12. The partition assembly includes a fixed plate and a movable plate 3. The fixed plate is placed horizontally at the rear of the housing 1 and connected to the inner side wall of the housing 1. The movable plate 3 is arranged to move back and forth relative to the fixed plate, and is used to cooperate with the fixed plate to separate the upper space 11 from the lower space 12 or to connect the upper space 11 from the lower space 12.

[0040] The cabinet 1 is equipped with an upper bowl rack 4 and a lower bowl rack 5 that can be pulled out from the front and back. The upper bowl rack 4 is located in the upper space 11, and the lower bowl rack 5 is located in the lower space 12.

[0041] The above are existing technologies and will not be elaborated further here.

[0042] The portions of the door 2 corresponding to the upper space 11 and lower space 12 when the door is closed are referred to as the upper part and lower part of the door 2, respectively. The upper part of the door 2 is a portion that is prone to contamination. Specifically, the portion of the upper part of the door 2 covered by the lower dish rack 5 when the door 2 is open is the portion that is prone to contamination.

[0043] 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.

[0044] 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 21 can be referred to in the Chinese utility model patent "Structure of Door 2 for Dishwasher and Dishwasher" with application number CN202321317157.8 (publication number CN220293571U).

[0045] For the detergent dispensing device, please refer to the application number CN202310612132.9 (publication number CN116509302A) entitled "A detergent dispensing mechanism, door structure and dishwasher for dishwasher".

[0046] like Figure 3 , 7 As shown, the spray element 6 is hollow inside, and has spray holes 61 that communicate with its interior. When the door 2 is closed, the spray holes 61 of the spray element 6 are connected to the washing chamber, and the easily contaminated parts of the door 2 are located on the spray path of the spray holes 61. Of course, the spray holes 61 can also face other areas of the door 2.

[0047] In this embodiment, the spray element 6 is located inside the door body 2. The inner wall of the door body 2 has spray holes 21 that communicate with the spray holes 61. When the door body 2 is closed, the spray holes 21 are located at the top of the easily contaminated parts of the door body 2, and the spray holes 21 face downwards. In this way, the spray element 6 is hidden inside the door body 2 and does not occupy space in the washing chamber. A sealing gasket 9 is provided between the spray element 6 and the door body 2. The sealing gasket 9 has through holes that correspond one-to-one with the spray holes 21 to prevent water leakage between the spray element 6 and the door body 2.

[0048] To increase the spray area, the nozzle 21 is cone-shaped with a gradually expanding diameter along the water flow direction.

[0049] The spray element 6 is a strip extending in the left-right direction, and there are multiple spray holes 61 that are spaced apart along the length of the spray element 6. The spray holes 21 and through holes are all arranged in a one-to-one correspondence. This allows for multi-point spraying and a wide spray range.

[0050] like Figure 4 , 5 As shown in Figure 6, the bottom of the cabinet 1 is provided with a water cup 7 that can store water. The spray component 6 is connected to the water cup 7 through a water pipe 8, and the water cup 7 in the dishwasher itself is used to supply water to the spray component 6.

[0051] To prevent the water pipe 8 from affecting the opening and closing of the door 2, the water pipe 8 is a flexible hose that can be bent. The hose can adaptively expand and contract when the door 2 is opened and closed. The hose can be made of corrugated pipe. The door 2 is provided with a through hole 22 near its bottom to allow the water pipe 8 to pass through. The through hole 22 plays a certain guiding role for the hose and prevents the water pipe 8 from being clamped during the opening and closing of the door 2, thus affecting the water flow.

[0052] The inlet end of the water pipe 8 is equipped with a valve (not shown in the figure) that can open or close the inlet end of the water pipe 8. This allows the valve to be opened or closed depending on whether the easily contaminated parts of the door body 2 need to be cleaned. The valve can be an existing valve such as a solenoid valve.

[0053] The door body 2 is provided with a positioning element (not shown in the figure) near the spray hole 21 for positioning the water pipe 8 so that the water pipe 8 can be reliably connected to the spray element 6. The positioning element can be in the form of a snap fastener, such as a C-shaped cross section, so that the water pipe 8 can be inserted into the snap fastener through the notch.

[0054] The cleaning logic for the easily soiled parts of the dishwasher in this embodiment is as follows:

[0055] 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.

[0056] 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.

[0057] In this embodiment, a spray element 6 is provided on the door body 2. When the door body 2 is closed, the valve on the water pipe 8 is opened, water is supplied, and the water in the spray element 6 washes the easily contaminated parts of the door body 2 through the spray holes 21 on the door body 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.
