Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a dish rack lifting mechanism and a dishwasher. Background Technology

[0002] The dish rack is an important component of a dishwasher, used to hold the dishes to be washed. Since different dishes come in various sizes, some dishwashers have a rack lifting mechanism to adjust the rack height. This allows the space between the rack and the top wall of the dishwasher, or between two racks, to be flexibly adjusted according to the size of the dishes to be placed. This enables the dishwasher to accommodate dishes of different sizes, thus increasing its versatility.

[0003] Existing dish rack lifting mechanisms typically adjust the height of the dish rack by installing rollers at different heights. When a user wants to adjust the dish rack from one height to another, the rack needs to be completely pulled out and reinstalled on the roller assembly at the new height. This adjustment can only be made when the rack is unloaded. This method is cumbersome and inefficient, as each height adjustment requires pulling out and reinstalling the rack, causing significant inconvenience to the user. Furthermore, due to limited internal space, these mechanisms usually only have two sets of roller assemblies at different heights, limiting the adjustment to between two heights and making them unsuitable for various user needs. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a bowl basket lifting mechanism, which allows for easy adjustment of the bowl basket height simply by raising or lowering it, making operation simple and convenient.

[0033] Reference Figures 1 to 5This utility model provides a dish rack lifting mechanism, including a fixed plate, a movable plate 100 (not shown in the figure), and an adjustment assembly. The fixed plate is equipped with at least one roller, which can be installed on the guide rail of the dishwasher inner tub. The movable plate 100 is used to connect the dish rack, thereby allowing the dish rack to move in and out of the inner tub via the roller on the fixed plate. The movable plate 100 is movably mounted on the fixed plate and can move up and down relative to the fixed plate. The movable plate 100 has a slide groove 110 arranged in the vertical direction. The inner wall of the slide groove 110 has at least two sets of snap-fit ​​structures arranged in the vertical direction. Each set of snap-fit ​​structures includes two oppositely arranged slots 120. The inner bottom wall of each slot 120 has a first guide surface 121 extending from top to bottom into the slide groove 110. The bottom of the slide groove 110 has a downwardly extending pressing groove 111, and the top of the slide groove 110 has a downwardly protruding pressing block 112. The adjusting assembly is mounted on the fixed plate and embedded in the slide groove 110. The adjusting assembly includes two sliders 200 and an elastic part 210 located between the two sliders 200. The two sliders 200 are movably mounted on the fixed plate and can move relative to each other, moving closer or further apart. The movable plate 100 can move upward relative to the fixed plate, causing the two sliders 200 to engage with two slots 120 of one set of engaging structures. Both sliders 200 can press against the corresponding first guide surface 121 and press upward against the inner top wall of the corresponding slot 120. When the adjusting assembly is embedded in the pressing groove 111, the two sliders 200 can move relative to each other and lock together. When the two sliders 200 are locked together, the movable plate 100 can move downward relative to the fixed plate, and the pressing block 112 can be inserted downward between the two sliders 200, separating the two sliders 200 from each other.

[0034] In the bowl basket lifting mechanism of this utility model embodiment, a sliding groove 110 is provided on the movable plate 100 and an adjustment component is provided on the fixed plate. The two opposite side walls of the sliding groove 110 are provided with slots 120. The slots 120 have a first guide surface 121 extending from top to bottom into the sliding groove 110. The adjustment component includes two elastically connected sliders 200. Thus, when it is necessary to adjust the height of the bowl basket, the movable plate 100 can be moved upward relative to the fixed plate. The two sliders 200 can move along the first guide surface 121 of the two side slots 120 and sequentially engage with the slots 120 of each set of engaging components from bottom to top. When the bowl basket is adjusted to a suitable height, the movement of the movable plate 100 is stopped, so that the two sliders 200 are engaged in the two slots 120 of the engaging components at the appropriate height. At this time, the two sliders 200 can press upward against the inner top wall of the corresponding slot 120 and cooperate to support the movable plate 100, thereby fixing the bowl basket at a suitable height. When the height of the bowl basket needs to be adjusted downwards, the movable plate 100 can be moved upwards relative to the fixed plate to the highest position, so that the adjusting component is engaged in the pressing groove 111. The two sliders 200 can move closer to each other and lock together under the pressing action of the pressing groove 111 relative to the two side walls. The elastic part 210 contracts. At this time, the movable plate 100 can be moved downwards and the adjusting component can move upwards along the sliding groove 110. When the movable plate 100 moves downwards to the lowest position, the pressing block 112 can press downwards against the two sliders 200 and continue to be embedded downwards between the two sliders 200, so that the two sliders 200 separate from each other. At this time, the two sliders 200 can elastically reset under the action of the elastic part 210. Thus, the movable plate 100 can be moved upwards and the above actions can be repeated. The whole process of adjusting the height of the bowl basket is simple and convenient. You only need to lift the bowl basket or put it down. Since there are at least two sets of locking components, the bowl basket has at least two adjustable heights and can be adjusted between at least two heights. It has high applicability and can meet the diverse height adjustment needs of users.

[0035] It is understandable that during the upward movement of the movable plate 100 relative to the fixed plate, the two sliders 200 can move along the first guide surface 121 of the two side slots 120 and sequentially engage with the slots 120 of each set of engaging components from bottom to top. Specifically, when the slider 200 moves along the first guide surface 121 of one of the slots 120, the elastic part 210 contracts. When the slider 200 moves into the lower adjacent slot 120, the elastic element will elastically reset and push the slider 200 to continue pressing against the first guide surface 121 of the lower slot 120.

[0036] Reference Figures 3 to 5In some embodiments, the adjustment assembly further includes a rotating shaft 220, which is mounted on a fixed plate and passes through a slide groove 110. Both sliders 200 are rotatably mounted on the rotating shaft 220 and can rotate relative to each other to move closer or further apart.

[0037] By adopting the above structure, both sliders 200 are rotatably mounted on the fixed plate via the rotating shaft 220. Under the elastic action of the elastic part 210, the two sliders 200 can press against the first guide surfaces 121 on both sides. When the movable plate 100 moves upward relative to the fixed plate, the two sliders 200 can move along the first guide surfaces 121 of the slots 120 on both sides and be inserted into the slots 120 of each set of snap-fit ​​components from bottom to top. When the adjusting component is engaged in the pressing groove 111, the two sliders 200 can rotate around the rotating shaft 220 and lock together under the pressing action of the pressing groove 111 relative to the side walls. The elastic part 210 contracts. At this time, the movable plate 100 can be moved downward so that the pressing block 112 can press down against the two sliders 200. If the movable plate 100 is moved downward, the pressing block 112 can continue to be inserted between the two sliders 200, so that the two sliders 200 rotate around the rotating shaft 220 and separate from each other. At this time, the two sliders 200 can elastically reset under the action of the elastic part 210. Thus, the movable plate 100 can be moved upward and the above actions can be repeated. The whole process of adjusting the height of the bowl basket is simple and convenient. You only need to lift the bowl basket or put it down.

[0038] It is understood that in the above structure, the elastic part 210 can be a torsion spring installed on the rotating shaft 220 and pressing against the two sliders 200, or the elastic part 210 can be a compression spring sandwiched between the two sliders 200. This utility model does not make specific limitations on this.

[0039] Reference Figure 1 and Figure 2 In some embodiments, both sliders 200 are slidably mounted on the fixed plate and can move relative to each other, moving closer or further apart. The elastic part 210 is a compression spring sandwiched between the two sliders 200.

[0040] By adopting the above structure, when the movable plate 100 moves upward until the adjusting component is engaged in the pressing groove 111, the two sliders 200 can move closer to each other and lock under the pressing action of the pressing groove 111 relative to the side walls. The elastic part 210 contracts. At this time, the movable plate 100 can be moved downward so that the pressing block 112 can press down against the two sliders 200. If the movable plate 100 continues to move downward, the pressing block 112 can continue to be embedded between the two sliders 200, so that the two sliders 200 move away from each other and separate. At this time, the two sliders 200 can elastically reset under the action of the elastic part 210. Thus, the movable plate 100 can continue to be moved upward to adjust the height of the basket. The whole process of adjusting the height of the basket is simple and convenient. You only need to lift the basket or put it down.

[0041] Reference Figures 1 to 5 In some embodiments, the inner wall of the slide 110 is also provided with a guide groove 130 arranged in the vertical direction. The adjustment assembly also includes a guide part 201 passing through the guide groove 130. Both sliders 200 are connected to the guide part 201. Thus, the guide part 201 can guide the movement of the two sliders 200, avoiding the phenomenon of positional deviation of the two sliders 200 during the vertical movement of the movable plate 100, thereby ensuring the stability of the vertical movement of the basket.

[0042] Reference Figures 3 to 5 In some embodiments, one of the two sliders 200 is provided with a first locking part 230 and the other is provided with a second locking part 240. The first locking part 230 has an elastic locking groove 231. When the adjusting component moves into the pressing groove 111, the inner walls on both sides of the pressing groove 111 can push the two sliders 200 to move closer to each other. The second locking part 240 can be locked into the elastic locking groove 231 and locked with the first locking part 230. When the second locking part 240 is locked in the elastic locking groove 231, the movable plate 100 can move downward relative to the fixed plate, and the pressing block 112 can push the two sliders 200 to move away from each other and cause the second locking part 240 to disengage from the elastic locking groove 231.

[0043] By adopting the above structure, when the adjusting component moves to the pressing groove 111, the two sliders 200 can approach each other under the pressing action of the pressing groove 111 relative to the side walls, so that the second locking part 240 is engaged in the elastic locking groove 231 of the second locking part 240. Thus, the movable plate 100 can be moved downward. When the movable plate 100 moves downward until the pressing block 112 presses down between the two sliders 200, the pressing block 112 can continue to be embedded downward between the two sliders 200 and the second locking part 240 is disengaged from the elastic locking groove 231. At this time, the two sliders 200 can be elastically reset under the action of the elastic part 210. Thus, the movable plate 100 can continue to be moved upward and the above action can be repeated. The whole process of adjusting the height of the bowl basket is simple and convenient. It only requires lifting or lowering the bowl basket.

[0044] Reference Figure 1 and Figure 2 In some embodiments, one of the two sliders 200 is provided with a first magnetic attraction part 250, and the other is provided with a second magnetic attraction part 260 that can magnetically attract the first magnetic attraction part 250. When the adjusting component moves into the extrusion groove 111, the inner walls on both sides of the extrusion groove 111 can push the two sliders 200 to move closer to each other and make the first magnetic attraction part 250 and the second magnetic attraction part 260 magnetically attract and adhere to each other. When the first magnetic attraction part 250 and the second magnetic attraction part 260 magnetically attract and adhere to each other, the movable plate 100 can move downward relative to the fixed plate, and the extrusion block 112 can push the two sliders 200 to move away from each other and make the first magnetic attraction part 250 and the second magnetic attraction part 260 separate from each other.

[0045] By adopting the above structure, when the adjusting component moves to the pressing groove 111, the two sliders 200 can approach each other under the pressing action of the pressing groove 111 relative to the side walls, so that the first magnetic suction part 250 and the second magnetic suction part 260 can magnetically attract each other and lock together. Thus, the movable plate 100 can be moved downward. When the movable plate 100 moves downward until the pressing block 112 presses down between the two sliders 200, the pressing block 112 can continue to be embedded downward between the two sliders 200 and the first magnetic suction part 250 and the second magnetic suction part 260 separate. At this time, the two sliders 200 can elastically reset under the action of the elastic part 210. Thus, the movable plate 100 can continue to move upward and repeat the above action. The whole process of adjusting the height of the bowl basket is simple and convenient. You only need to lift the bowl basket or put it down.

[0046] Understandably, in the above structure, when the two sliders 200 separate under the elastic action of the elastic part 210, the magnetic attraction force between the first magnetic attraction part 250 and the second magnetic attraction part 260 is less than the elastic force of the elastic part 210. Therefore, the first magnetic attraction part 250 and the second magnetic attraction part 260 cannot attract each other during the upward movement of the movable plate 100 relative to the fixed plate. When the first magnetic attraction part 250 and the second magnetic attraction part 260 attract each other under the squeezing action of the squeezing groove 111, the magnetic attraction force between the first magnetic attraction part 250 and the second magnetic attraction part 260 is greater than the elastic force of the elastic part 210. Therefore, the designed first magnetic attraction part 250 and the second magnetic attraction part 260 cannot separate each other during the downward movement of the movable plate 100 relative to the fixed plate.

[0047] Reference Figures 1 to 5 In some embodiments, each of the two sliders 200 has a guide portion 201 at its upper end. The guide portion 201 extends outward from bottom to top, and the pressing block 112 can press downward against the two guide portions 201 and embed itself between the two sliders 200. Thus, the guide portion 201 can guide the pressing block 112 to embed itself between the two sliders 200 so that the two sliders 200 can be separated and unlocked.

[0048] Reference Figures 1 to 5 In some embodiments, the outer walls of the two sliders 200 are provided with a second guide surface 202 extending inward from top to bottom, and the inner top wall of each slot 120 has an abutment surface arranged in the horizontal direction; when the two sliders 200 are inserted into the two slots 120 of one set of snap-fit ​​structures, the two second guide surfaces 202 are in contact with the corresponding first guide surfaces 121, and the two sliders 200 can press upward against the corresponding abutment surfaces and cooperate to support the movable plate 100.

[0049] By adopting the above structure, the second guide surface 202 can fit closely with the corresponding first guide surface 121, thereby making the movement of the movable plate 100 more stable and the connection between the movable plate 100 and the fixed plate more compact, facilitating the support of the slider 200 for the movable plate 100. Furthermore, since each slot 120 has a horizontally arranged abutment surface on its inner top wall, the slider 200 can stably abut against the inner top wall of the slot 120, making the support of the slider 200 for the movable plate 100 more stable.

[0050] In some embodiments, the movable plate 100 is provided with a cover, and a slide groove 110 is formed on one side wall of the movable plate 100 near the fixed plate. The cover covers the movable plate 100 and closes the slide groove 110. The cover has a clearance groove arranged in the vertical direction. The fixed plate is provided with a connecting part that movably passes through the clearance groove and extends into the slide groove 110. An adjustment component is installed on the connecting part.

[0051] By adopting the above structure, the cover design can prevent the adjustment components from being exposed, thereby facilitating the protection of the adjustment components and reducing the risk of damage to the basket lifting mechanism.

[0052] An embodiment of this utility model also proposes a dishwasher, which is equipped with a dish rack lifting mechanism of any of the above embodiments, thereby enabling convenient height adjustment of the dish rack. During the adjustment process, it is only necessary to lift or lower the dish rack, which is simple and convenient to operate. Furthermore, the dish rack can be adjusted between at least two heights, making it highly adaptable and able to meet the diverse height adjustment needs of users.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
