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 and 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 is the "half-cavity washing" mode, which not only makes full use of the cabinet space but also helps to save 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. This is the "full-cavity washing" mode, which washes the dishes in both the upper and lower spaces simultaneously.

[0006] However, in the "full cavity washing" mode, the partition assembly is ineffective and occupies space inside the cabinet; moreover, the current partition assembly has a single function, only dividing the interior of the cabinet into upper and lower spaces, without any other additional functions. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a dishwasher with a multifunctional partition assembly, based on the current state of the technology.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a dishwasher, comprising...

[0009] The box-shaped structure has an open front.

[0010] The door is movably located at the front opening of the box, allowing the box to be opened or closed.

[0011] A partition assembly is disposed within the housing, the partition assembly comprising:

[0012] A fixing plate is placed horizontally at the rear of the box and connected to the inner side wall of the box. When the door is closed, there is a notch between the fixing plate and the door.

[0013] A movable plate is arranged to move relative to the fixed plate in a front-back direction. The movable plate can move forward to a first position to cover the gap and move backward to a second position to open the gap. When the movable plate is in the first position, the partition assembly can divide the inner cavity of the box into a relatively independent upper space and a lower space. When the movable plate is in the second position, the upper space and the lower space are connected.

[0014] Its features include

[0015] A spray element is provided on the partition assembly, and the spray element is provided with a water inlet hole and a water spray hole that are connected to its interior.

[0016] Preferably, the spraying components include a first spraying component and a second spraying component. The first spraying component is disposed on a movable plate and can move back and forth with the movable plate. In this way, as the movable plate moves, the spraying components can perform dynamic spraying, resulting in a large spraying range and fewer blind spots.

[0017] To supply water to the first spray element, the dishwasher preferably further includes a water supply pipe located behind the partition assembly, the water supply pipe being connected to the water inlet of the first spray element via a retractable connecting pipe. The retractable connecting pipe extends and retracts without affecting the forward and backward movement of the movable plate.

[0018] The connecting pipe can be a corrugated pipe or a pipe with a first pipe body and a second pipe body that are inserted into each other. The rear end of the first pipe body is connected to the water supply pipe, and the front end of the second pipe body is connected to the water inlet of the first spray element. The second pipe body can move relative to the first pipe body in the front-back direction.

[0019] Preferably, the movable plate is provided with a water passage, and the front end of the second pipe is connected to the water inlet of the first spray element through the water passage. Compared with directly connecting the connecting pipe to the first spray element, this can reduce the length of the connecting pipe.

[0020] Preferably, the movable plate has at least two first spray elements. The water passage includes a main channel and branch channels corresponding to the number of first spray elements. One end of the main channel is connected to the front end of the second pipe, and the other end of the main channel branches to form the branch channels. The outlet of each branch channel is connected to a corresponding outlet hole of the first spray element. This allows for multiple first spray elements, enabling multi-point spraying with a large spray range and few dead zones. More preferably, the first spray elements can rotate relative to the movable plate around a vertically extending axis, further increasing the spray range.

[0021] When the movable plate is in the second position, the movable plate can be located above or below the fixed plate. Alternatively, the movable plate may include a first plate body and a second plate body. The first plate body can move back and forth relative to the second plate body. The first spray element is disposed on the first plate body. When the movable plate is in the first position, the first plate body, the second plate body, and the fixed plate are arranged sequentially from front to back. When the movable plate is in the second position, the first plate body and the first spray element are both embedded in the second plate body, and the second plate body is embedded in the fixed plate.

[0022] Preferably, the first pipe is fixedly installed in the fixed plate, the second pipe is fixedly installed in the second plate, and the water passage is set in the first plate. In this way, the connecting pipe is hidden in the partition assembly, which does not occupy additional space inside the box. In addition, the connecting pipe will automatically extend and retract during the movement of the moving plate, which is more convenient.

[0023] To prevent the first plate from detaching from the second plate when it moves forward, a first limiting structure is provided between the first plate and the second plate to limit the movement of the first plate. To prevent the second plate from detaching from the fixed plate when it moves forward, a second limiting structure is provided between the second plate and the fixed plate to limit the movement of the second plate.

[0024] The first limiting structure can have various structural forms. In a simple case, the second plate has a first receiving groove for the first plate to be received. The front end of the first receiving groove is provided with a first limiting part, and the rear end of the first plate is provided with a second limiting part that can abut against the rear wall surface of the first limiting part. The first limiting part and the second limiting part together constitute the first limiting structure.

[0025] The second limiting structure can have various structural forms. In a simple case, the fixing plate has a second receiving groove for the second plate body to be received. The front end of the second receiving groove is provided with a third limiting part, and the rear end of the second plate body is provided with a fourth limiting part that can abut against the rear wall surface of the third limiting part. The third limiting part and the fourth limiting part together constitute the second limiting structure.

[0026] Preferably, the second spray element is mounted on the fixed plate, and the water supply pipe is connected to the second spray element through a water pipe. In this way, the second spray element on the fixed plate can work whether it is a full-cavity wash or a half-cavity wash, which increases the number of spray elements in the box and is beneficial for cleaning.

[0027] Preferably, the water pipe is embedded in the fixed plate. This results in a compact structure, and the water pipe does not occupy additional space in the housing. More preferably, the second spray element can rotate relative to the corresponding water pipe about a vertically extending axis, thus providing a large spray range.

[0028] Compared with the prior art, the advantages of this utility model are: the partition assembly of this utility model can not only be used to connect or separate the upper and lower spaces of the cabinet to realize the cleaning mode of "full cavity washing" or "half cavity washing", but also the partition assembly can be used to install spray components. The spray components, together with other spray structures in the cabinet, can improve the cleaning effect on tableware. The partition assembly has multiple functions. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] like Figures 1-6As shown, the dishwasher of this preferred embodiment includes a cabinet 1, a door, a partition assembly A, and a spray unit.

[0037] The front of the box 1 is open, and a door is movably disposed at the front opening of the box 1, thereby opening or closing the box 1. A partition assembly A is disposed in the box 1. The partition assembly A includes a fixed plate 2 and a movable plate. The fixed plate 2 is horizontally placed at the rear of the box 1 and connected to the inner side wall of the box 1. When the door is closed, there is a notch between the fixed plate 2 and the door.

[0038] The movable plate is arranged to move relative to the fixed plate 2 in the front-back direction. The movable plate can move forward to a first position to cover the gap and move backward to a second position to open the gap. When the movable plate is in the first position, the partition assembly A can divide the inner cavity of the box 1 into a relatively independent upper space 11 and a lower space 12. When the movable plate is in the second position, the upper space 11 and the lower space 12 are connected.

[0039] The above are existing technologies, and will not be elaborated further here.

[0040] The spray element is mounted on the partition assembly A, and has water inlet holes and spray holes that communicate with its interior. The spray element can adopt an existing spray arm structure, which can be strip-shaped or disc-shaped.

[0041] In this embodiment, the spray system includes a first spray component 3 and a second spray component 4. The first spray component 3 is mounted on a movable plate and can move back and forth with the movable plate. This allows the first spray component to perform dynamic spraying during the movement of the movable plate, resulting in a large spraying range and few blind spots. Preferably, the first spray component 3 can rotate relative to the movable plate around a vertically extending axis, for example, by rotating under the drive of water flow.

[0042] A water supply pipe 5 is provided on the rear side of the partition assembly A. The water supply pipe 5 is connected to the water inlet of the first spray component 3 through a connecting pipe that can extend and retract back and forth. The connecting pipe can extend and retract back and forth so as not to affect the forward and backward movement of the moving plate.

[0043] The second spray element 4 is mounted on the bottom wall of the fixed plate 2. The water supply pipe 5 is connected to the second spray element 4 via a water pipe 7, which is embedded in the fixed plate 2. This allows the spray elements on the fixed plate 2 to operate regardless of whether it is a full-cavity or half-cavity wash, increasing the number of spray elements in the housing 1 and facilitating cleaning. The water pipe 7 does not occupy additional space in the housing 1. Preferably, the second spray element 4 can rotate relative to the corresponding water pipe 7 around a vertically extending axis, thus expanding the spray range. In this embodiment, there are two second spray elements 4.

[0044] like Figure 4As shown, the connecting pipe includes a first pipe body 61 and a second pipe body 62 that fit together in an insert configuration. The rear end of the first pipe body 61 is connected to the water supply pipe 5, and the second pipe body 62 can move relative to the first pipe body 61 in a front-to-back direction. The front end of the second pipe body 62 is connected to the water inlet of the first spray element 3. Specifically, a water passage is provided in the moving plate, and the front end of the second pipe body 62 is connected to the water inlet of the first spray element 3 through the water passage. Water in the water supply pipe 5 passes sequentially through the first pipe body 61, the second pipe body 62, and the water passage into the first spray element 3.

[0045] like Figure 5 As shown, the moving plate has at least two first spray elements 3. The water passage includes a main channel 81 and branch channels 82 corresponding to the number of first spray elements 3. One end of the main channel 81 is connected to the front end of the second pipe body 62, and the other end of the main channel 81 branches to form branch channels 82. The water outlet of each branch channel 82 is connected to the water outlet of the first spray element 3. In this way, there are multiple first spray elements 3, which can spray multiple points, with a large spray range and few dead spots.

[0046] like Figure 3 , 4 As shown, the movable plate includes a first plate body 8 and a second plate body 9. The first plate body 8 can move back and forth relative to the second plate body 9. The first spraying component 3 is disposed on the first plate body 8. When the movable plate is in the first position, the first plate body 8, the second plate body 9 and the fixed plate 2 are arranged sequentially from front to back. When the movable plate is in the second position, the first plate body 8 and the first spraying component 3 are both embedded in the second plate body 9, and the second plate body 9 is embedded in the fixed plate 2.

[0047] The first pipe body 61 is fixedly installed in the fixed plate 2, and the second pipe body 62 is fixedly installed in the second plate 9. The water passage is set in the first plate 8. The first plate 8 and the second pipe body 62 are inserted into each other, and a seal or rubber coating is provided between them to prevent water leakage. During the movement of the moving plate, the connecting pipe will automatically extend and retract, which is quite convenient.

[0048] To prevent the first plate 8 from detaching from the second plate 9 when it moves forward, a first limiting structure is provided between the first plate 8 and the second plate 9 to limit the movement of the first plate 8. The second plate 9 has a first receiving groove 91 for the first plate 8 to be received. The front end of the first receiving groove 91 is provided with a first limiting part 92, and the rear end of the first plate 8 is provided with a second limiting part 83 that abuts against the rear wall surface of the first limiting part 92. The first limiting part 92 and the second limiting part 83 together constitute the first limiting structure.

[0049] To prevent the second plate 9 from detaching from the fixed plate 2 when it moves forward, a second limiting structure is provided between the second plate 9 and the fixed plate 2 to restrict the movement of the second plate 9. The fixed plate 2 has a second receiving groove 21 for accommodating the second plate 9. The front end of the second receiving groove 21 is provided with a third limiting part 22, and the rear end of the second plate 9 is provided with a fourth limiting part 93 that abuts against the rear wall surface of the third limiting part 22. The third limiting part 22 and the fourth limiting part 93 together constitute the second limiting structure.
