Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a telescopic shelf, shelf assembly and dishwasher. Background Technology

[0002] In household appliances such as dishwashers and sterilizers, shelves are usually needed to place tableware. For example, dishwashers are usually equipped with two or three shelves to place various tableware or other items that need to be washed.

[0003] Currently, as users increasingly demand multifunctionality from shelves, traditional shelf structures with fixed volumes lack flexibility in use and are unable to meet the needs of multifunctional applications.

[0004] Therefore, it is urgent to improve the structure of the shelving to enhance its flexibility of use. Utility Model Content

[0005] This utility model provides a telescopic shelf, a shelf assembly, and a dishwasher to solve the technical problem that traditional shelf structures have fixed volumes and lack sufficient flexibility in use.

[0006] To achieve the above objectives, this utility model provides a telescopic shelf, comprising:

[0007] The first frame group and the second frame group together form a receiving cavity;

[0008] The second frame group overlaps with the first frame group, and the second frame group and the first frame group are movably arranged relative to each other along a first direction to adjust the overlap length between the second frame group and the first frame group, so that the volume of the accommodating cavity is adjustable.

[0009] This application provides a telescopic shelf, in which a second frame group overlaps with a first frame group and is movably arranged relative to each other along a first direction. This allows for adjustment of the overlap length between the second and first frame groups, facilitating adjustment of the volume of the accommodating cavity according to the quantity and size of the tableware. When the telescopic shelf is not in use, increasing the overlap length between the second and first frame groups reduces the volume of the accommodating cavity, saving space occupied by the telescopic shelf. When more tableware or other items need to be placed, decreasing the overlap length between the second and first frame groups increases the volume of the accommodating cavity, improving its capacity. The telescopic shelf can be used in conjunction with the main shelf to improve the utilization of the internal space of the dishwasher drum, or it can be removed and used independently, increasing the flexibility and practicality of the telescopic shelf and significantly enhancing the functionality and user satisfaction of the dishwasher.

[0010] In one possible implementation, the first frame group includes a first frame body having a first overlap portion, and the second frame group includes a second frame body having a second overlap portion, the second overlap portion overlapping the first overlap portion and slidingly disposed relative to the first overlap portion.

[0011] The telescopic shelf also includes a locking structure, which is disposed at the position where the second overlapping part and the first overlapping part overlap each other, so as to lock the relative position of the second frame group and the first frame group.

[0012] In one possible implementation, the locking structure includes:

[0013] A fixing part is provided in one of the first overlapping part and the second overlapping part, and a fixing hole is provided in the fixing part;

[0014] An adjusting strip is disposed in the other of the first overlapping portion and the second overlapping portion, and the adjusting strip has at least two adjusting holes spaced apart along the first direction:

[0015] A locking element, which passes through the fixing hole and the adjusting hole, to lock the relative position of the second frame group and the first frame group.

[0016] In one possible implementation, the first overlapping portion includes a first overlapping base plate and a first side plate connected to both sides of the first overlapping base plate, and the second overlapping portion includes a second overlapping base plate and a second side plate connected to both sides of the second overlapping base plate. The second overlapping base plate overlaps the first overlapping base plate, and the second side plate overlaps the side of the first side plate facing the receiving cavity.

[0017] In one possible implementation, the telescopic shelf further includes a guide structure disposed at the position where the first overlap and the second overlap overlap each other;

[0018] The guiding structure includes a first guiding unit, the first guiding unit comprising:

[0019] The first guide groove is provided on at least one of the inner bottom wall of the first overlapping base plate and the outer bottom wall of the second overlapping base plate, and the first guide groove extends along the first direction;

[0020] The guide rod is provided on at least one of the inner bottom wall of the first overlapping base plate and the outer bottom wall of the second overlapping base plate, and the guide rod is slidably disposed in the first guide groove.

[0021] In one possible implementation, the guide structure further includes a second guide unit, which includes a second guide groove and a guide slider, the guide slider being slidably disposed within the second guide groove;

[0022] The first side plate has a flange at its top, which covers the top of the second side plate. A second guide groove is disposed within the flange, and a guided slider is connected to the top of the second side plate; or...

[0023] The top of the second side plate has a flange that covers the top of the first side plate. A second guide groove is disposed within the flange, and a guide slider is connected to the top of the first side plate.

[0024] In one possible implementation, the first frame group further includes a first skeleton connected to the bottom of the first frame, and the second frame group further includes a second skeleton connected to the bottom of the second frame, with at least one of the first skeleton and the second skeleton connected to the guide rod.

[0025] In one possible implementation, the first frame also has a limiting boss located at the end of the first overlap that is away from the second overlap.

[0026] When the overlap length between the second frame group and the first frame group is at its maximum, the second overlap portion abuts against the limiting boss.

[0027] This application also provides a shelf assembly, including:

[0028] The main shelf has a slide beam mounted on its top; and the telescopic shelf has sliding slots on opposite outer walls of the telescopic shelf, the sliding slots being detachably connected to and slidingly engaged with the slide beam to adjust the position of the telescopic shelf relative to the main shelf.

[0029] This application also provides a dishwasher that includes the telescopic shelf described above; or, includes the shelf assembly described above.

[0030] This utility model provides a telescopic shelf, a shelf assembly, and a dishwasher. Since the shelf assembly includes a main shelf and the aforementioned telescopic shelf, it does not occupy the existing main shelf's storage space, thereby increasing the dish volume ratio of the dishwasher's inner drum. Users can adjust the position according to different dish placement scenarios to improve the cleaning effect on the dishes.

[0031] This utility model provides a telescopic shelf, shelf assembly and dishwasher. Since the volume of the telescopic shelf is variable, it can accommodate dish racks of different sizes of dishwashers and meet the needs of both inside and outside the dishwasher.

[0061] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0062] Dishwashers typically include multiple shelves, also known as dish racks, such as upper shelves, lower shelves, and middle shelves. Due to different user habits and the need to improve the utilization of the inner drum space, the existing fixed shelf structure is not flexible enough and cannot meet the diverse needs of tableware placement.

[0063] This application provides a telescopic shelf that can reduce or increase the volume of the accommodating cavity. When it is necessary to reduce the volume and space occupied by the telescopic shelf, the overlap length between the second frame group and the first frame group can be increased. When it is necessary to place more tableware and other items, the overlap length between the second frame group and the first frame group can be reduced to increase the accommodating capacity. This helps to improve the utilization rate of the internal space of the dishwasher drum, improve the flexibility and practicality of the telescopic shelf, and significantly enhance the functionality and user satisfaction of the dishwasher.

[0064] The telescopic shelf, shelf assembly, and dishwasher provided in the embodiments of this utility model are described below with reference to the accompanying drawings.

[0065] refer to Figure 1 , Figure 2 and Figure 3As shown, this application provides a telescopic shelf, including: a first frame group 10 and a second frame group 20, the second frame group 20 and the first frame group 10 together forming a receiving cavity 30; the second frame group 20 and the first frame group 10 overlap each other, and the second frame group 20 and the first frame group 10 are movably arranged relative to each other along a first direction, so as to adjust the overlap length of the second frame group 20 and the first frame group 10, so that the volume of the receiving cavity 30 is adjustable.

[0066] In this embodiment, the first direction reference Figure 1 and Figure 2 The arrow X in the diagram indicates the direction.

[0067] This application provides a telescopic shelf, in which a second frame group 20 overlaps with a first frame group 10 and is movably arranged relative to each other along a first direction. This allows for adjustment of the overlap length between the second frame group 20 and the first frame group 10, facilitating the adjustment of the volume of the accommodating cavity 30 according to the quantity and size of the tableware. When the telescopic shelf is not in use, increasing the overlap length between the second frame group 20 and the first frame group 10 reduces the volume of the accommodating cavity 30, thus saving space occupied by the telescopic shelf. When more tableware or other items need to be placed, reducing the overlap length between the second frame group 20 and the first frame group 10 increases the volume of the accommodating cavity 30, improving its capacity. This helps to improve the utilization rate of the internal space of the dishwasher's inner drum, enhances the flexibility and practicality of the telescopic shelf, and significantly improves the functionality and user satisfaction of the dishwasher.

[0068] This application provides a telescopic shelf with a accommodating cavity 30 for placing tableware or other items. The size and volume of the accommodating cavity 30 can be changed by adjusting the overlap length between the second frame group 20 and the first frame group 10, thereby adapting to different usage needs. Both the second frame group 20 and the first frame group 10 have openings at their opposite ends. The second frame group 20 enters the first frame group 10 through the opening, thus achieving an overlap between the second frame group 20 and the first frame group 10.

[0069] In one possible implementation method, refer to Figure 1 , Figure 2 and Figure 3 As shown, the first frame group 10 includes a first frame body 11, the first frame body 11 includes a first overlapping portion 111, the second frame group 20 includes a second frame body 21, the second frame body 21 includes a second overlapping portion 211, the second overlapping portion 211 overlaps the first overlapping portion 111 and slides relative to the first overlapping portion 111.

[0070] The design of the second overlapping part 211 and the first overlapping part 111 should ensure the stability of the structure during sliding, achieve smooth sliding, and prevent problems such as accidental slippage or damage. The telescopic shelf achieves adjustable volume, reducing its size to save space when a smaller volume is needed, and expanding its volume to accommodate more or larger items when a larger volume is required.

[0071] In one possible implementation, referring to Figures 3, 4 and 5, the telescopic shelf further includes a locking structure 40, which is disposed at the position where the second overlap 211 overlaps with the first overlap 111 to lock the relative position of the second frame group 20 and the first frame group 10.

[0072] In one possible implementation method, refer to Figures 3 and 4. Figure 5 and Figure 6 As shown, the locking structure 40 includes a fixing part 41, an adjusting strip 42, and a locking member 43. The fixing part 41 is disposed in one of the first overlapping part 111 and the second overlapping part 211, and a fixing hole 411 is provided in the fixing part 41. The adjusting strip 42 is disposed in the other of the first overlapping part 111 and the second overlapping part 211, and at least two adjusting holes 421 are provided in the adjusting strip 42 at intervals along a first direction. The locking member 43 passes through the fixing hole 411 and one adjusting hole 421 to lock the relative position of the second frame group 20 and the first frame group 10.

[0073] The fixing part 41 is used to provide a fixed position. The adjusting strip 42 has at least two adjusting holes 421 arranged at intervals along the first direction, so that the user can adjust the length of the overlap between the second overlapping part 211 and the first overlapping part 111 as needed, so that the different adjusting holes 421 are aligned with the fixing holes 411, so that the locking member 43 can pass through the aligned fixing holes 411 and one adjusting hole 421 to lock the position of the first frame group 10 and the second frame group 20.

[0074] After the overlap lengths of the second overlap portion 211 and the first overlap portion 111 are determined, the locking member 43 can pass through the fixing hole 411 and an adjustment hole 421 aligned with the fixing hole 411 to lock the relative positions of the first frame group 10 and the second frame group 20. This ensures that the telescopic shelf will not accidentally slide or change shape during use, guaranteeing the stability of the telescopic shelf. The locking member 43 is designed for easy user operation, allowing for quick and easy locking and unlocking to adjust the volume of the accommodating cavity 30.

[0075] In one possible implementation, the fixing hole 411 can be a circular hole.

[0076] This application uses locking element 43 to lock the positions of the first frame group 10 and the second frame group 20, which enhances the functionality and user experience of the telescopic shelf and ensures safety and stability in different usage scenarios.

[0077] In one possible implementation, the fixing part 41 is disposed on the first overlapping part 111, and the adjusting strip 42 is disposed on the second overlapping part 211. Alternatively, the fixing part 41 is disposed on the second overlapping part 211, and the adjusting strip 42 is disposed on the first overlapping part 111.

[0078] In one possible implementation, referring to Figures 3, 5 and 6, the adjusting strip 42 is elongated and has multiple adjusting holes 421 arranged at intervals along a first direction. The adjusting holes 421 can be circular, waist-shaped, arc-shaped, etc.

[0079] In one possible implementation, the number of adjustment holes 421 can be, for example, 3, 5, 6, 8, 10, or 12.

[0080] In one possible implementation, the locking element 43 includes, but is not limited to, a pin or a component with a partially columnar structure. In one possible implementation, referring to Figures 3, 6, and 7, the first overlapping portion 111 includes a first overlapping base plate 1111 and first side plates 1112 connected to both sides of the first overlapping base plate 1111, and the second overlapping portion 211 includes a second overlapping base plate 2111 and second side plates 2112 connected to both sides of the second overlapping base plate 2111. The second overlapping base plate 2111 overlaps the first overlapping base plate 1111, and the second side plates 2112 overlap the side of the first side plates 1112 facing the receiving cavity 30.

[0081] The second side plate 2112 overlaps the side of the first side plate 1112 facing the accommodating cavity 30, enhancing the stability of the entire telescopic shelf and preventing loosening or misalignment during the relative sliding of the first frame group 10 and the second frame group 20.

[0082] The first overlapping base plate 1111 and the second overlapping base plate 2111 provide a base surface for overlapping. The first side plate 1112 can be integrally formed and connected to both sides of the first overlapping base plate 1111, and the second side plate 2112 can be integrally formed and connected to both sides of the second overlapping base plate 2111. The first side plate 1112 and the second side plate 2112 provide a physical barrier, which can effectively prevent tableware placed in the receiving cavity 30 from falling off from both sides of the receiving cavity 30. The first side plate 1112 and the second side plate 2112 also enhance the stability of the entire telescopic shelf, making it more reliable when carrying items.

[0083] In one possible implementation, the first overlapping base plate 1111, the first side plate 1112, the second overlapping base plate 2111, and the second side plate 2112 are all in a grid pattern.

[0084] In one possible implementation, referring to Figures 3, 6, and 7, the telescopic shelf further includes a guide structure 50, which is disposed at the position where the first overlapping portion 111 and the second overlapping portion 211 overlap. The guide structure 50 is used to guide the first frame group 10 and the second frame group 20 to slide relative to each other better, preventing problems such as movement deviation, misalignment, and jamming when guiding the first frame group 10 and the second frame group 20 to slide relative to each other, thus ensuring the telescopic performance of the telescopic shelf.

[0085] In one possible implementation, refer to Figures 3 and 6. Figure 7 As shown, the guide structure 50 includes a first guide unit, which includes a first guide groove 51 and a guide rod 52. At least one of the inner bottom wall of the first overlapping base plate 1111 and the outer bottom wall of the second overlapping base plate 2111 is provided with the first guide groove 51, which extends along a first direction. At least one of the inner bottom wall of the first overlapping base plate 1111 and the outer bottom wall of the second overlapping base plate 2111 is provided with the guide rod 52, which is slidably disposed in the first guide groove 51.

[0086] In one possible implementation, since the second overlapping base plate 2111 slides on the first overlapping base plate 1111, reference... Figure 11 As shown, the inner bottom wall of the first overlapping base plate 1111 is provided with a first guide groove 51. The first guide groove 51 can extend along a first direction and have an arc-shaped cross-section. Referring to Figures 3, 6, and 7, a guide rod 52 is provided at the end of the second overlapping base plate 2111 near the first frame group 10. The guide rod 52 can be a cylindrical rod. When the second overlapping base plate 2111 slides on the first overlapping base plate 1111, the guide rod 52 slides in the first guide groove 51, which guides the mutual sliding of the second frame group 20 and the first frame group 10, ensuring that the mutual sliding of the second frame group 20 and the first frame group 10 is controlled and smooth.

[0087] In one possible implementation, the outer bottom wall of the second overlapping base plate 2111 is provided with a first guide groove 51, which may extend along a first direction and have an arc-shaped cross-section; the first overlapping base plate 1111 is provided with a guide rod 52, which slides along the first guide groove 51 on the outer bottom wall of the second overlapping base plate 2111 to guide the sliding of the second frame group 20 and the first frame group 10, ensuring that the sliding of the second frame group 20 and the first frame group 10 is controlled and stable.

[0088] In one possible implementation, both the inner bottom wall of the first overlapping base plate 1111 and the outer bottom wall of the second overlapping base plate 2111 are provided with first guide grooves 51. A guide rod 52 is provided at the end of the second overlapping base plate 2111 near the first frame assembly 10, and a guide rod 52 is also provided at the end of the first overlapping base plate 1111 near the second frame assembly 20. This achieves a dual guiding function, improving the stability and alignment accuracy of the structure, as there are guiding devices in two different directions or positions to control the movement. This dual-guiding design is typically used in movements requiring high precision and reliability to ensure that the relative movement between components is smooth and controllable during operation.

[0089] In one possible implementation, as shown in Figures 3, 4 and 9, the top of one of the first side plate 1112 and the second side plate 2112 has a flange 2113 that covers the top of the other of the first side plate 1112 and the second side plate 2112.

[0090] In one possible implementation, the guide structure 50 further includes a second guide unit comprising a second guide groove 53 and a guide slider 54, the guide slider 54 being slidably disposed within the second guide groove 53; the top of the first side plate 1112 has a flange 2113 covering the top of the second side plate 2112, the second guide groove 53 being disposed within the flange 2113, and the guide slider 54 being connected to the top of the second side plate 2112; or, the top of the second side plate 2112 has a flange 2113 covering the top of the first side plate 1112, the second guide groove 53 being disposed within the flange 2113, and the guide slider 54 being connected to the top of the first side plate 1112. The second guide unit provides lateral guidance, allowing the second side plate 2112 to slide smoothly on the first overlap portion 111 of the first side plate 1112, reducing friction and wear.

[0091] In one possible implementation, the top of the first side plate 1112 has a flange 2113, which is turned toward the inside of the receiving cavity 30. A second guide groove 53 is disposed on the bottom wall of the flange 2113, and the guided slider 54 is connected to the top of the second side plate 2112.

[0092] In another possible implementation, the top of the second side plate 2112 has a flange 2113, which is turned outward of the receiving cavity 30. The second guide groove 53 is disposed on the bottom wall surface of the flange 2113, and the guided slider 54 is connected to the top of the first side plate 1112.

[0093] In one possible implementation, the second guide groove 53 extends along the first direction, and the cross-sectional shape of the second guide groove 53 can be arc-shaped. The cross-sectional shape of the guide slider 54 is the same as that of the second guide groove 53. During the sliding process between the second frame group 20 and the first frame group 10, whether they move closer to each other or move further away from each other along the first direction, the guide slider 54 slides within the second guide groove 53, which can better guide the relative movement of the second frame group 20 and the first frame group 10. This helps to prevent problems such as tilting or jamming between the second frame group 20 and the first frame group 10, ensuring that the telescopic shelf can smoothly perform telescopic movement to adjust the volume of the receiving cavity 30.

[0094] In one possible implementation, the guide slider 54 may be integrally connected to the top of the first side plate 1112 or the top of the second side plate 2112.

[0095] In this application, the second guide unit realizes the guiding function of the first side plate 1112 and the second side plate 2112. By setting the second guide groove 53 in the flange 2113 and letting the guide slider 54 slide in the second guide groove 53, the first overlapping part 111 and the second overlapping part 211 can move smoothly, which increases the stability and reliability of the telescopic shelf telescopic movement.

[0096] In one possible implementation, referring to Figures 3, 4, and 9, the first frame 11 further includes a limiting boss 113. The limiting boss 113 is located at the end of the first overlapping portion 111 furthest from the second overlapping portion 211. When the overlap length between the second frame group 20 and the first frame group 10 is at its maximum, the second overlapping portion 211 abuts against the limiting boss 113. The function of the limiting boss 113 is to provide a physical barrier to prevent the relative overlap length between the second frame group 20 and the first frame group 10 from exceeding a certain range, ensuring a safe and stable overlap between the second frame group 20 and the first frame group 10.

[0097] In one possible implementation, the limiting boss 113 protrudes toward the second overlapping portion 211.

[0098] In one possible implementation, the bottom wall of the first overlap 111 is lowered relative to the first frame 11, such that when the second frame group 20 overlaps with the first frame group 10, the inner bottom wall of the second overlap 211 is flush with the inner bottom wall of the first frame 11, providing a stable load-bearing function.

[0099] Referring to Figures 7 and 9, to facilitate the securing of tableware, a dedicated toothed bracket 13 is provided in both the first frame 11 and the second frame 21. The toothed bracket 13 includes multiple protruding teeth. By placing tableware between two adjacent protruding teeth, the toothed bracket 13 can stably support and secure the tableware, such as plates, bowls, or other tableware items, helping to prevent the tableware from sliding or tipping over within the receiving cavity 30. The placement of the toothed bracket 13 also helps users organize and retrieve tableware more systematically, improving convenience and efficiency.

[0100] In one possible implementation, referring to Figures 3, 4, and 9, the first frame group 10 further includes a first skeleton 12 connected to the bottom of the first frame 11. The second frame group 20 further includes a second skeleton 22 connected to the bottom of the second frame 21.

[0101] In one possible implementation method, refer to Figure 3 As shown, both the first frame 12 and the second frame 22 include staggered first support rods 121 and second support rods 122. The staggered positions of the first support rods 121 and second support rods 122 can be connected as a whole by welding or by binding them together with wire or the like. The first frame 12 is supported on the outer bottom wall of the first frame 11, which can improve the overall load-bearing capacity of the first frame assembly 10. The second frame 22 is supported on the outer bottom wall of the second frame 21, which can improve the overall load-bearing capacity of the second frame assembly 20.

[0102] In one possible implementation, referring to Figures 3, 7, and 8, the outer bottom wall of the first frame 11 and the outer bottom wall of the second frame 21 each have multiple snap-fit ​​portions 112 to snap onto the corresponding first support rod 121 or second support rod 122, thereby improving the stability of the support.

[0103] An elastic groove is formed in the snap-fit ​​part 112, and the first support rod 121 and the second support rod 122 are snapped into the corresponding snap-fit ​​part 112.

[0104] In one possible implementation, a first support rod 121 extends along a first direction, and a second support rod 122 extends along a second direction. The first frame 11 has a first baffle 114 and a first overlapping portion 111 at opposite ends along the first direction. The second frame 21 has a first baffle 114 and a second overlapping portion 211 at opposite ends along the first direction. The second direction is perpendicular to the first direction, and the second direction is referenced... Figure 16 and Figure 17 The arrow Y in the diagram indicates the direction.

[0105] In one possible implementation method, refer to Figure 9 and Figure 10As shown, the first frame 11 and the second frame 21 each have a second baffle 115 at their opposite ends along the second direction, and the second support rod 122 is supported on the outer wall of the two second baffles 115 at their opposite ends along the second direction, thereby improving the support effect on the second baffles 115.

[0106] In one possible implementation method, refer to Figure 8 and Figure 10 As shown, the second support rod 122 has bending portions 1221 connected to its opposite ends along the second direction. The outer wall of the second baffle 115 has an anti-detachment groove 1151, and the bending portions 1221 extend into the anti-detachment groove 1151. This prevents the first frame 12 from detaching from the first frame 11 and the second frame 22 from detaching from the second frame 21, ensuring stable support for the first frame 11 and the second frame 21 by the first frame 12 and the second frame 22, respectively.

[0107] In one possible implementation method, refer to Figure 3 and Figure 4 As shown, at least one of the first frame 12 and the second frame 22 is connected to the guide rod 52. Specifically, the first support rod 121 of at least one of the first frame 12 and the second frame 22 may be connected to the corresponding guide rod 52.

[0108] refer to Figure 10 , Figure 12 and Figure 13 As shown, this application also provides a shelf assembly, including: a main shelf 60 and the aforementioned telescopic shelf. A slide beam 61 is mounted on the top of the main shelf 60. The telescopic shelf has sliding grooves 116, which are formed on opposite outer walls of the telescopic shelf. The sliding grooves 116 slidably engage with the slide beam 61 to adjust the position of the telescopic shelf relative to the main shelf 60. The telescopic shelf moves flexibly on the main shelf 60, providing adjustable storage space and facilitating flexible adjustment of the storage space size.

[0109] The sliding slots 116 may be located on opposite outer walls of the telescopic shelf. For example, in one possible implementation, the two sliding slots 116 may be located on the outer walls of the first baffle 114 of the first frame 11 and the second frame 21, respectively. The sliding slots 116 extend in a second direction and slide in engagement with the slide beam 61 to adjust the position of the telescopic shelf relative to the main shelf 60. Alternatively, in other possible implementations, the two sliding slots 116 may be located on the outer walls of the second baffle 115 of the first frame 11 and the second frame 21, respectively.

[0110] In one possible implementation method, refer to Figure 14As shown, the slide beam 61 can be a metal rod. Both ends of the slide beam 61 are welded to the top of the main shelf 60. The slide beam 61 provides support and guidance for the aforementioned telescopic shelf, facilitating user operation. Figure 16 and Figure 17 As shown, adjust the left and right positions of the telescopic shelf according to the arrangement of tableware in the main shelf 60.

[0111] In one possible implementation, the two ends of the slide beam 61 can also be slidably connected to the top of the main shelf 60, so that the distance between the two slide beams 61 is consistent with the length of the telescopic shelf after it has been extended or retracted. This makes it easy to support telescopic shelves of different extension lengths on the main shelf 60, thereby improving the flexibility and versatility of use.

[0112] refer to Figure 13 , Figure 14 and Figure 15 As shown, the main shelf 60 can be at least one of the upper shelf, lower shelf, or middle shelf of the dishwasher. Taking the telescopic shelf as an example, the two ends of the slide beam 61 are welded to the top of the middle shelf, without the need to arrange the slide beam 61 on the upper shelf and the lower shelf.

[0113] The present application provides a shelf assembly in which the telescopic shelf can be detached and used as a drain basket or as a tableware storage basket. Alternatively, it can be a slide beam 61 installed on the top of the main shelf 60 for placing tableware, thereby increasing the volume of tableware and improving the utilization rate of the internal space of the existing dishwasher to meet the needs of users in different usage environments.

[0114] refer to Figure 18 As shown, since there is plenty of space above the upper, lower, or middle shelves, adding these telescopic shelves increases the dishwasher's washing capacity and accommodates different dishwashing and placement needs.

[0115] In one possible implementation method, refer to Figure 3 and Figure 9 As shown, when the shelf assembly is used inside the dishwasher, the telescopic shelf is in a fully retracted state. At this time, the second overlapping part 211 abuts against the limiting boss 113. The adjustment hole 421 of the first frame group 10 and the second frame group 20 that is furthest apart along the first direction is aligned with the fixing hole 411 so that the locking member 43 can pass through the aligned fixing hole 411 and the adjustment hole 421, thereby achieving relative fixation of the first frame group 10 and the second frame group 20.

[0116] refer to Figure 19As shown, this application also provides a dishwasher, including the telescopic shelf described above; or, including the shelf assembly described above. The shelf assembly described above is disposed inside the inner tub of the dishwasher.

[0117] This application also provides a dishwasher, which includes a dishwasher body 70, the structure of which refers to existing structures.

[0118] The other structural details of the dishwasher are similar to those in existing designs and will not be described in detail here.

[0119] This utility model provides a telescopic shelf, a shelf assembly, and a dishwasher. Since the shelf assembly includes a main shelf 60 and the aforementioned telescopic shelf, it does not occupy the existing storage space of the main shelf 60, thereby increasing the tableware volume ratio of the dishwasher's inner drum. Users can adjust the position according to different tableware placement scenarios to improve the cleaning effect of the tableware.

[0120] This utility model provides a telescopic shelf, shelf assembly and dishwasher. Since the volume of the telescopic shelf is variable, it can accommodate dish racks of different sizes of dishwashers and meet the needs of both inside and outside the dishwasher.
