Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a partition assembly for a dishwasher and 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 invention patent application CN202211198278.5 (publication number CN115486780A) discloses a cleaning machine, comprising a housing with an inner cavity; a partition assembly disposed within the inner cavity of the housing, the partition assembly dividing the inner cavity of the housing into relatively independent upper and lower spaces, the partition assembly including a fixed plate horizontally positioned in the middle of the housing and connected to the inner sidewall of the housing; and a movable plate arranged to move horizontally relative to the fixed plate, the movable plate cooperating with the fixed plate to separate or connect the upper and lower spaces, the direction of movement of the movable plate separating the upper and lower spaces being defined as a first direction, and the direction of movement of the movable plate connecting the upper and lower spaces being defined as a second direction.

[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 place 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] However, in the aforementioned patent, the movable plate is located above or below the fixed plate. When the notch is open, the movable plate overlaps the upper or lower side of the fixed plate. When the notch is closed, at least a portion of the movable plate intersects with the fixed plate and covers the notch. In other words, the movable plate and the fixed plate are not flush, resulting in low precision. Utility Model Content

[0007] The first technical problem to be solved by this utility model is to provide a partition assembly for a dishwasher in which the movable plate can be flush with the fixed plate, in light of the current state of the technology.

[0008] The second technical problem to be solved by this utility model is to provide a dishwasher that uses the above-mentioned partition assembly, in view of the current state of the prior art.

[0009] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a partition assembly for a dishwasher, comprising...

[0010] A fixing plate, wherein the front portion of the fixing plate has a notch;

[0011] A movable plate is connected to a fixed plate and can move back and forth relative to the fixed plate. The movable plate can move forward to a first position to close the notch and move backward to a second position to open the notch. When the movable plate is in the second position, the movable plate is located above or below the fixed plate.

[0012] The drive mechanism is used to drive the moving plate to move back and forth.

[0013] The feature is that it further includes a lifting mechanism, which is connected to the moving plate drive and is used to drive the moving plate to move up and down. When the moving plate is in the first position, the upper surface of the moving plate is flush with the upper surface of the fixed plate in the horizontal direction.

[0014] The drive mechanism can have various structural forms, such as an electric push rod, or the drive mechanism can include a drive component;

[0015] The push-pull component is driven by a drive component and its power is transmitted to the moving plate via a lifting mechanism. The push-pull component can move back and forth. In this way, the push-pull component and the lifting mechanism can share the power of the drive component, simplifying the structure. Alternatively, the push-pull component can be equipped with a single drive component, and the lifting mechanism can be equipped with a separate drive source, allowing the drive mechanism and the lifting mechanism to operate independently.

[0016] The lifting mechanism can use a lifting cylinder, but it is costly and complex in structure. Preferably, the front part of the fixed plate is also provided with a limiting member, and when the moving plate is in the first position, the front wall of the moving plate abuts against the limiting member.

[0017] The lifting mechanism is a lifting rod. The first end of the lifting rod is rotatably connected to a movable plate via a first pin, and the second end is rotatably connected to a push-pull component via a second pin. Both the first and second pins extend in the left-right direction. When the movable plate is in the first position, the height of the first pin is L1; when the movable plate is in the second position, the height of the first pin is L2, where L1 > L2 or L1 < L2. The lifting rod has a simple structure. When the front wall of the movable plate abuts against the limiting component, the push-pull component continues to push the movable plate forward. Because the movable plate cannot move further forward, the lifting rod rotates, causing the movable plate to rise and become flush with the fixed plate. When it is necessary to move the movable plate from the first position to the second position, the push-pull component pulls the movable plate backward. Because the rear wall of the movable plate abuts against the fixed plate, the movable plate cannot move backward at this time. Pulling the movable plate backward causes the lifting rod to rotate, causing the movable plate to move downward. Once the movable plate and the fixed plate are misaligned in the front-back direction, the movable plate can move backward to the second position under the action of the driving mechanism.

[0018] To improve the stability of the moving plate's lifting and lowering, the wall surface of the moving plate facing away from the fixed plate when it is in the second position is called the mounting surface. Mounting components are provided on the mounting surface, and these components are rotatably connected to the first pin. There are at least two mounting components spaced apart along the front-to-back direction. Correspondingly, there are at least two lifting rods. This arrangement of multiple lifting rods acts on the moving plate, resulting in a large and even force distribution and good lifting and lowering stability.

[0019] Preferably, the push-pull component includes a pull rope and a push-pull rod. One end of the pull rope is connected to a drive component, and the other end of the pull rope is connected to the push-pull rod. The push-pull rod extends in the front-back direction and is connected to a lifting rod.

[0020] If the movable plate is in the second position, the drooping pull rope will affect the appearance and take up space. Therefore, preferably, the rear of the fixed plate is provided with a receiving groove, and the driving component is located in the receiving groove. When the movable plate is in the second position, the pull rope is also located in the receiving groove, which is aesthetically pleasing and saves space.

[0021] In order to guide the movement trajectory of the push-pull rod so that the moving plate can move back and forth, the fixed plate is provided with a guide rail extending in the front-back direction, and the push-pull rod is located in the guide rail and can move along the guide rail.

[0022] To ensure smooth forward and backward movement of the lifting rod as the moving plate moves, the fixed plate is provided with a first sliding groove and a second sliding groove. A first roller is rotatably mounted on the first pin and is rotatably disposed in the first sliding groove. A second roller is rotatably mounted on the second pin and is rotatably disposed in the second sliding groove. The cooperation between the rollers and the sliding grooves reduces friction, thereby minimizing the resistance caused by the lifting rod to the forward and backward movement of the moving plate.

[0023] To ensure smooth movement and lifting of the movable plate, guide rails, a first slide groove, and a second slide groove are provided on the left and right side plates of the fixed plate. The push-pull component and lifting rod are correspondingly arranged, and both push-pull components are driven and connected to the driving component. This ensures that the movable plate is subjected to force from both sides, resulting in multiple points of force distribution that allow for smooth movement and lifting, while also preventing tilting.

[0024] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows: a dishwasher, characterized in that it includes a cabinet, a door, and the aforementioned partition assembly. The cabinet has an open front side, and the door is movably disposed at the open front side of the cabinet to open and close the cabinet. The partition assembly is disposed in the cabinet, and the fixed plate is arranged horizontally. When the door is closed and the movable plate is in a first position, the front wall surface of the movable plate abuts against the door. The partition assembly divides the interior of the cabinet into an independent upper space and a lower space. When the movable plate is in a second position, the upper space and the lower space are connected.

[0025] Compared with the prior art, the advantages of this utility model are as follows: This utility model is provided with a lifting mechanism that can drive the moving plate to rise and fall. This allows the lifting mechanism to drive the moving plate to move vertically, so that when the moving plate is in the first position, its upper surface is flush with the upper surface of the fixed plate, thus improving the precision of the partition assembly. When the moving plate needs to be in the second position, the lifting mechanism drives the moving plate to move vertically, so that the moving plate and the fixed plate are offset horizontally, which does not affect the forward and backward movement of the moving plate.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an adhesive connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model patent based on the specific circumstances.

[0034] like Figures 1-5 As shown, the dishwasher of this preferred embodiment includes a cabinet (not shown in the figure), a door (not shown in the figure), and a partition assembly. The partition assembly includes a fixed plate 1, a movable plate 2, a drive mechanism 3, and a lifting mechanism.

[0035] The front of the fixed plate 1 has a notch 11. The movable plate 2 is connected to the fixed plate 1 and can move back and forth relative to the fixed plate 1. The driving mechanism 3 is used to drive the movable plate 2 to move back and forth. The movable plate 2 can move forward to a first position to close the notch 11 and move backward to a second position to open the notch 11. When the movable plate 2 is in the second position, it is located above or below the fixed plate 1. In this embodiment, when the movable plate 2 is in the second position, it is located below the fixed plate 1. Figure 5 As shown.

[0036] The lifting mechanism is connected to the moving plate 2 and is used to drive the moving plate 2 to move up and down. When the moving plate 2 is in the first position, such as... Figure 4As shown, the upper surface of the movable plate 2 is flush with the upper surface of the fixed plate 1 in the horizontal direction to improve the precision of the partition assembly. The front part of the fixed plate 1 is also provided with a limiting member 13. When the movable plate 2 is in the first position, the front wall surface of the movable plate 2 abuts against the limiting member 13.

[0037] In this embodiment, the drive mechanism 3 includes a drive member 31 and a push-pull member. The push-pull member is drivenly connected to the drive member 31 and transmits power to the moving plate through a lifting mechanism so that the push-pull member can move back and forth. The drive member 31 can be a motor.

[0038] In this embodiment, the push-pull component includes a pull rope 32 and a push-pull rod 33. One end of the pull rope 32 is connected to the driving component 31, and the other end of the pull rope 32 is connected to the push-pull rod 33, which extends in the front-back direction. The rear of the fixed plate 1 is provided with a receiving groove 12, and the driving component 31 is disposed in the receiving groove 12. When the moving plate 2 is in the second position, because the pull rope 32 is flexible, the pull rope 32 can also be located in the receiving groove 12, which is aesthetically pleasing and saves space.

[0039] The lifting mechanism is a lifting rod 4. The first end of the lifting rod 4 is rotatably connected to the moving plate 2 via a first pin 41, and the second end of the lifting rod 4 is rotatably connected to the push-pull rod 33 via a second pin 42. Both the first pin 41 and the second pin 42 extend in the left-right direction. When the moving plate 2 is in the first position, the height of the first pin 41 is L1; when the moving plate 2 is in the second position, the height of the first pin 41 is L2, where L1 > L2. However, if the moving plate 2 is in the second position and is located above the fixed plate 1, then L1 < L2.

[0040] When the front wall of the movable plate 2 abuts against the limiting member 13, the push-pull member continues to push the movable plate 2 forward. Since the movable plate 2 cannot move forward any further, the lifting rod 4 rotates, causing the movable plate 2 to move upward and become flush with the fixed plate 1. When it is necessary to move the movable plate 2 from the first position to the second position, the push-pull member pulls the movable plate 2 backward. Since the rear wall of the movable plate 2 abuts against the fixed plate 1, the movable plate 2 cannot move backward at this time. Pulling the movable plate 2 backward will cause the lifting rod 4 to rotate, causing the movable plate 2 to move downward. Once the movable plate 2 and the fixed plate 1 are misaligned in the front-back direction, the movable plate 2 can move backward to the second position under the action of the drive mechanism 3.

[0041] The wall surface of the movable plate 2 facing away from the fixed plate 1 when it is in the second position is called the mounting surface. Mounting members 5 are provided on the mounting surface, and the mounting members 5 are rotatably connected to the first pin 41. At least two mounting members 5 are spaced apart along the front-rear direction, and correspondingly, there are at least two lifting rods 4. In this way, multiple lifting rods 4 act on the movable plate 2, resulting in a large and even force on the movable plate 2 and good lifting stability.

[0042] In addition, to facilitate the mounting of the mounting component 5 onto the movable plate 2, a U-shaped component 51 extending in the front-to-back direction is provided on the mounting surface, and the mounting component 5 is disposed in the U-shaped groove of the U-shaped component 51. In this embodiment, there are two U-shaped components 51, spaced apart in the left-to-right direction. First, the U-shaped component 51 is glued to the mounting surface of the movable plate 2, and then the mounting component 5 is positioned in the U-shaped groove of the U-shaped component 51 by screws.

[0043] The fixed plate 1 is provided with a guide rail 14 extending in the front-to-back direction. The push-pull rod 33 is located in the guide rail 14 and can move along the guide rail 14 to guide the movement trajectory of the push-pull rod 33.

[0044] In addition, the fixed plate 1 is provided with a first sliding groove 51 and a second sliding groove 15. A first roller 43 is rotatably mounted on the first pin 41 and is rotatably mounted in the first sliding groove 51. A second roller 44 is rotatably mounted on the second pin 42 and is rotatably mounted in the second sliding groove 15. The cooperation between the rollers and the sliding grooves reduces friction, thereby reducing the resistance caused by the lifting rod 4 to the forward and backward movement of the moving plate 2.

[0045] In this embodiment, guide rails 14, first sliding grooves 51, and second sliding grooves 15 are provided on the side plates 16 on both the left and right sides of the fixed plate 1. Push-pull components and lifting rods 4 are correspondingly arranged, and both push-pull components are driven and connected to the driving component 31. In this way, the moving plate 2 is subjected to force on both the left and right sides, so that the moving plate 2 can move and rise smoothly, and the force is evenly distributed to prevent the moving plate 2 from tilting.

[0046] In addition, the front ends of the side plates 16 on both the left and right sides of the fixing plate 1 are provided with limiting members 13.

[0047] The front of the enclosure is open, and the door is movably positioned at the front opening to open and close the enclosure. The connection between the enclosure and the door can be achieved using existing technology. A partition assembly is located inside the enclosure. The fixed plate 1 is horizontally positioned. When the door is closed and the movable plate 2 is in the first position, the front wall of the movable plate 2 abuts against the door. The partition assembly divides the interior of the enclosure into an independent upper space and a lower space. When the movable plate 2 is in the second position, the upper space and the lower space are connected.
