[0044] Dishwasher 100, body 10, guide rail 20, support device 30, support frame 31, first support bar 311, second support bar 312, third support bar 313, support assembly 32, support body 321, main body 3211, rolling support 3212, roller frame 32121, support frame 3201, extension frame 3202, support rib 3203, roller 32122, rotating shaft 32123, guide rail limiting structure 3213, limiting rib 3214, connecting structure 322, positioning part 3221, first locking block 3222, second locking block 3223, third locking block 3224, bracket assembly 33, fixed bracket 331, movable bracket 332, protective frame 34, inner frame 341, outer frame 342, insert 351, limiting piece 352, extension section 353. Detailed Implementation

[0045] Currently, dishwashers typically offer either a one-piece or multi-functional cutlery tray (with an adjustable bottom mesh). One-piece trays have poor compatibility with the size of the cutlery placed on or below them, while the mainstream multi-functional trays (with adjustable bottom mesh) offer limited improvement in the utilization of the dishwasher's internal space and do not slide smoothly.

[0046] This utility model relates to the field of household appliance technology, and in particular to a (non-integral) cutlery tray with a movable bottom mesh. Addressing the pain points of usage and demand mentioned above, this utility model proposes a support device (cutlery tray) with a recessed center (fixed bracket) and movable left and right brackets that can slide left and right, and a dishwasher with it. The support device, as a carrier supporting cutlery, together with the upper dish rack, determines the space utilization rate of the middle and upper parts of the dishwasher's inner cavity. The support device mainly includes a support frame, a protective frame (e.g., a plastic frame), support components (located on the left and right sides of the support device), movable brackets (located on the left and / or right half of the support device), fixed brackets, handles, and other parts. Each component is assembled onto the support frame via slots and buckles. The movable brackets can slide left and right along guide rails. The recessed fixed bracket in the middle provides a larger loading space for the tray. When loading large cutlery into the lower dish rack, the movable brackets on the left and right sides can be slid towards the center, or only one side can be slid (in which case the sliding distance is the farthest). This can be flexibly selected according to the usage scenario, freeing up the original space to meet placement requirements.

[0047] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0048] like Figures 1 to 3 The supporting device 30 according to an embodiment of the present invention includes: a supporting frame 31, a support component 32, and a bracket assembly 33. The supporting frame 31 provides support for the bracket to improve its stability and reduce or prevent twisting or deformation of the fixed bracket 331 during use. The support component 32 connects to the supporting frame 31. When the supporting frame 31 is installed into the cavity of the dishwasher 100, the support component 32 supports the supporting device 30 within the dishwasher 100's inner tub and can cooperate with the guide rails and / or guide rail supports of the inner tub to guide the supporting device 30 to move back and forth. The bracket assembly 33 is disposed on the supporting frame 31 and can hold cutlery such as knives and forks.

[0049] Specifically, the support assembly 32 is connected to the left and right sides of the support frame 31, and is used to move the support device 30 into and out of the loading space. The bracket assembly 33 is connected to the support frame 31 and is used to support the object to be cleaned. The bracket assembly 33 and the support assembly 32 are separate structures.

[0050] According to the embodiment of the present invention, the support component 32 and the bracket component 33 of the bearing device 30 are designed as separate parts. Compared with an integrated design, since the support component 32 is directly assembled on the bearing frame 31, it is not affected by the structural strength and deformation of the bracket component 33, and has better structural strength and dimensional accuracy, thus making the pushing and pulling process of the bearing device 30 more stable and smooth. By setting the bracket component 33 and the support component 32 as separate structures, each module can be processed and designed separately, thereby simplifying the design of the bearing device 30 and realizing the modular design of the bearing device 30.

[0051] The supporting device 30 of this utility model slides back and forth along the guide rail via the support assembly 32. The guide rail is supported on the left and right sides of the inner cavity. The bracket assembly 33 may include a fixed bracket 331 and a movable bracket 332. The fixed bracket 331 is disposed on the supporting frame 31 and its relative position is fixed. The movable bracket 332 is disposed on the supporting frame 31 and can slide in the left and right direction. The fixed bracket 331 is recessed, and the movable bracket 332 can slide above the fixed bracket 331. The fixed bracket 331 may be disposed in the middle of the supporting frame 31. The movable bracket 332 may include multiple brackets disposed in the left and right halves of the supporting frame 31. The movable bracket 332 is provided with a sliding handle for holding and driving the movable bracket 332 to move left and right. The supporting frame 31 is also provided with a handle, and a metal plate is provided on the front of the handle.

[0052] The support assembly 32 may include a support body 321 and rollers 32122. The support body 321 may include a slot, a fastener, and a structure that mates with the rollers 32122 and the guide rail. The left and right support assemblies 32 are mounted on both sides of the support frame 31 via fasteners and slots. The rollers 32122 are mounted on the support body 321 through an opening in the support body 321. The support device 30 is mounted on the guide rail via the rollers 32122 and the guide rail limiting structure 3213, thereby enabling the bracket assembly 33 to move back and forth.

[0053] The support component 32 in this utility model can be connected to the load-bearing frame 31 by means of screw connection, snap connection or other fixing methods. This utility model provides some specific embodiments to realize the connection between the support component 32 and the load-bearing frame 31, which is not a limitation on the protection scope of this utility model.

[0054] like Figures 3 to 6In some embodiments, the support component 32 includes a support body 321 and a connecting structure 322. The support body 321 is used to move the bearing device 30 into and out of the loading space, and the connecting structure 322 is used to connect the support body 321 and the bearing frame 31. The connecting structure 322 can be used to stably install the support body 321 onto the bearing frame 31, achieving a stable connection between the support body 321 and the bearing frame 31. The connecting structure 322 can be connected to the support body 321, and the connecting structure 322 can be further connected to the support body 321 to form an integral structure.

[0055] Optionally, the support body 321 is located on the outside of the supporting frame 31, and the connecting structure 322 is located on the side of the support body 321 facing the supporting frame 31. The support body 321 can be connected to a guide rail on the inner liner, facilitating the sliding in and out of the supporting device 30. The location of the connecting structure 322 on the side of the support body 321 improves the stability of the connecting structure 322 by facilitating its connection to the supporting frame 31.

[0056] Among them, such as Figure 4 and Figure 5 The supporting frame 31 includes a first support bar 311 and a second support bar 312, which extend in the front-to-back direction and are distributed in the up-down direction. The connecting structure 322 includes a positioning part 3221 and a first locking block 3222. The positioning part 3221 is connected to the first support bar 311, and the supporting assembly 32 can rotate around the first support bar 311. The first locking block 3222 is snapped onto the second support bar 312. During assembly, the positioning part 3221 can be connected to the first support bar 311, and then the supporting assembly 32 can be rotated, and the first locking block 3222 can be connected to the second support bar 312, thereby realizing the connection between the supporting assembly 32 and the supporting frame 31, resulting in high assembly efficiency.

[0057] In addition, the supporting frame 31 may also include at least two third support bars 313, which extend in the vertical direction and are distributed in the front-back direction, and are connected to the first support bar 311 and the second support bar 312.

[0058] Optionally, one of the first support bar 311 and the second support bar 312 includes a first part and a second part distributed in a front-rear direction. The first part is offset from the second part in a direction away from the other of the first support bar 311 and the second support bar 312. The front and rear ends of the first part are provided with connecting bars for limiting the bearing frame 31. The first part can be connected to the rear end of the second part.

[0059] This includes, but is not limited to, the following implementation methods.

[0060] In one embodiment, the first support bar 311 includes a first part and a second part, which are distributed along the front-back direction. The first part can be connected to the rear end of the second part. The first part is offset away from the second part in a direction away from the second support bar 312. The front and rear ends of the first part are provided with connecting bars, which are arranged along the up-down direction. The connecting bars at the front and rear ends of the first part can be set to limit the support component 32.

[0061] In the second embodiment, the second support bar 312 includes a first part and a second part, which are distributed along the front-back direction. The first part can be connected to the rear end of the second part. The first part is offset away from the second part in a direction away from the first support bar 311. The front and rear ends of the first part are provided with connecting bars, which are arranged along the up-down direction. The connecting bars at the front and rear ends of the first part can be set to limit the support component 32.

[0062] Implementation method three can be a combination of implementation method one and implementation method two.

[0063] Optionally, the first support bar 311 may be located above the second support bar 312; or the first support bar 311 may be located below the second support bar 312.

[0064] In addition, the supporting frame 31 may include a left side, a right side, a front side and a rear side, wherein the left side and the right side may include the aforementioned first support bar 311 and second support bar 312, the front side is connected to the front end of the left side and the right side, and the rear side is connected to the rear end of the left side and the right side.

[0065] Optionally, the positioning part 3221 has a slot with an opening opposite to the first locking block 3222. This allows for quick connection between the positioning part 3221 and the first support bar 311, and facilitates the rotation of the support assembly 32 around the first support bar 311 during assembly, thereby improving the assembly efficiency and stability of the support assembly 32 and the load-bearing frame 31.

[0066] The first locking block 3222 has a first locking hole with an opening on the side opposite to the supporting frame 31, and the first locking hole extends through the first locking block 3222 in the front-to-back direction. The second support bar 312 is engaged with the first locking hole through the opening. This allows for quick assembly of the first locking block 3222 and the second support bar 312.

[0067] In addition, the first locking block 3222 can be configured to include a first fastener and a second fastener distributed in the vertical direction, and the first fastener and the second fastener are fastened to the upper and lower sides of the second support.

[0068] In addition, the support component 32 may also include a third latching block 3224, which includes a fifth latching position and a sixth latching position. The fifth latching position and the sixth latching position are offset in the front-back direction and are configured to be latched on the upper and lower sides of the first support part.

[0069] The support component 32 in this utility model can be assembled with the load-bearing frame 31 using a mating groove and staggered fastening method. During assembly, the support component 32 is held at a certain angle. First, the positioning part 3221 is inserted into the first support strip 311. The staggered third opening and sixth fastening position in the third buckle can ensure sufficient fastening force while simplifying the assembly, so that the support component 32 does not come out of the steel wire or wobble. Then, the support component 32 is rotated to fasten all the fastening positions to the corresponding mating steel wires, and the support component 32 is firmly assembled on both sides of the frame steel wire.

[0070] like Figures 9 to 12 In some embodiments, the supporting device 30 further includes a protective frame 34 that covers the supporting frame 31. The protective frame 34 includes an inner frame 341 located inside the supporting frame 31 and an outer frame 342 located outside the supporting frame 31. The inner frame 341 and the outer frame 342 are connected. A support assembly 32 is located on the left and right sides of the supporting frame 31 and is configured to limit the protective frame 34. The support assembly 32 can be used to limit the protective frame 34 to improve the connection stability between the protective frame 34 and the supporting frame 31.

[0071] The support component 32 in this utility model can limit the protective frame 34 in various ways, including but not limited to the following embodiments.

[0072] like Figure 10 In some embodiments, the support component 32 includes a limiting piece 352 disposed on the outside of the supporting frame 31, and the outer frame 342 includes an insert 351 sandwiched between the limiting piece 352 and the supporting frame 31. The cooperation between the limiting piece 352 and the supporting frame 31 enables the positioning of the insert 351. When the protective frame 34 has a tendency to twist around the supporting frame 31, the limiting piece 352 and the supporting frame 31 will restrict the twisting of the protective frame 34, thereby limiting the positioning of the protective frame 34.

[0073] like Figure 12In other embodiments, the first locking block 3222 has an extended section 353 that extends toward the interior space of the supporting frame 31 and protrudes from the inner side of the supporting frame 31. The extended section 353 abuts against the inner frame 341. This improves the positioning effect of the reinforcing section on the inner frame 341, further enhancing the stability of the protective frame 34. The extended section 353 can be used to limit the inner frame 341. When the protective frame 34 has a tendency to twist around the supporting frame 31, the stopping effect of the extended section 353 can restrict the twisting of the supporting frame 31, improving the stability of the protective frame 34.

[0074] In some embodiments, the first locking block 3222 is snapped to the second support bar 312, and the extended section 353 is provided on the side of the first locking block 3222 near the positioning part 3221.

[0075] In some embodiments of this invention, the combination of the aforementioned limiting piece 352 and the extended section 353 is used to limit the protective frame 34, preventing it from twisting and deforming. The left and right outer frames 342 of the protective frame 34 are designed with inserts 351. During assembly, the left insert 351 is inserted into the inside of the limiting piece 352 of the left support component 32, and the right insert 351 is inserted into the inside of the limiting piece 352 of the right support component 32. Furthermore, the support component 32 and the load-bearing frame 31 can be connected via a first positioning buckle. The first positioning buckle has an extended section 353 that corresponds to the surface of the inner frame 341 that corresponds to the outer frame 342. The limiting piece 352 restricts the outer frame 342 from twisting outwards, while the extended section 353 presses against the inner frame 341. When the protective frame 34 warps or is twisted by external force, the limiting piece 352 and the extended section 353 prevent the protective frame 34 from twisting and deforming.

[0076] In some embodiments, the supporting frame 31 further includes a third support strip 313 extending in the vertical direction. The connecting structure 322 further includes a second locking block 3223 having a second locking hole. The second locking hole has an opening on the side opposite to the supporting frame 31 and extends through the second locking block 3223 in the vertical direction. The second support strip 312 is engaged with the second locking hole through the opening. For example, the support assembly 32 further includes a second locking block 3223 that is snapped into the third support portion. Optionally, the second locking block 3223 includes a third latch and a fourth latch distributed in the front-rear direction, which are snapped into the front and rear sides of the third support portion.

[0077] In addition, the third support bar 313 connects the first support bar 311 and / or the second support bar 312. This improves the structural strength and stability of the load-bearing frame 31, thereby reducing problems such as swaying during the use of the load-bearing device 30 and enhancing the stability of the load-bearing device 30.

[0078] like Figure 7 and Figure 8 In some embodiments, the support assembly 32 includes a support body 321, which includes a main body portion 3211 and at least two rolling supports 3212. The main body portion 3211 is connected to the load-bearing frame 31. The rolling supports 3212 are used to connect to the guide rail and can move along the guide rail during use to facilitate the sliding of the load-bearing device 30 into and out of the load-bearing space. The at least two rolling supports 3212 include a first rolling support and a second rolling support arranged diagonally opposite each other, used to provide rolling support on opposite sides of the guide rail 20.

[0079] Optionally, such as Figure 7 The rolling support 3212 includes a roller frame 32121, a roller 32122, and a rotating shaft 32123. The roller frame 32121 is connected to the main body 3211, and an arrangement space is formed between the roller frame 32121 and the main body 3211. The roller 32122 is rotatably disposed in the arrangement space. The rotating shaft 32123 supports the roller 32122, and both ends of the rotating shaft 32123 are supported by the main body 3211 and the roller frame 32121, respectively.

[0080] The first and second rolling supports employ a diagonal roller design. After the tableware is loaded onto the support device 30, the two diagonally opposite (front upper and rear lower) rollers 32122 provide support. Additionally, the support body 321 may include a guide rail limiting structure 3213, which may include front lower and rear upper hook structures. The guide rail limiting structure 3213 serves a limiting function; therefore, the rollers 32122 are designed to be diagonally arranged. The rollers 32122 are inserted into the mating cavity structure through an opening structure. A limiting structure is designed at the bottom of the opening structure to prevent the rollers 32122 from detaching from their working position. The axle can be designed as an integral part of the support body 321. The materials of the axle and the support body 321 can be dissimilar materials (metal + plastic, or different types of plastic), and the rollers 32122 are mounted on the axle.

[0081] The roller frame 32121 includes a support frame 3201 that supports the rotating shaft 32123 and an extension frame 3202 that connects the support frame 3201 and the main body 3211. The extension frame 3202 in the first rolling support is located below the corresponding roller 32122 and is designed as a hollow structure. The extension frame 3202 in the second rolling support is located above the corresponding roller 32122 and is designed as a closed structure.

[0082] Optionally, the first rolling support can be located behind the second rolling support. The extension frame 3202 of the first rolling support is located below the corresponding roller 32122, and the extension frame 3202 of the second rolling support is located above the corresponding roller 32122. The extension frame 3202 of the first rolling support has a hollow structure, while the extension frame 3202 of the second rolling support has a closed structure. This improves the stability of the sliding frame and facilitates the stable rotation of the roller 32122.

[0083] The support body 321 is provided with a first opening structure, a first limiting structure and a first shaft hole. The first limiting structure is located between the first opening structure and the first shaft hole. The width of the first limiting structure is smaller than the maximum width of the first limiting part and the maximum width of the first shaft hole. The maximum width of the first opening structure is larger than the maximum width of the first shaft hole. The width of the first opening structure gradually decreases in the direction close to the first shaft hole. One end of the rotating shaft 32123 passes through the first shaft hole.

[0084] The roller frame 32121 is provided with a second opening structure, a second limiting structure and a second shaft hole. The second limiting structure is located between the second opening structure and the second shaft hole. The width of the second limiting structure is smaller than the maximum width of the second limiting part and the maximum width of the second shaft hole. The maximum width of the second opening structure is greater than the maximum width of the second shaft hole, and the width of the second opening structure gradually decreases in the direction close to the second shaft hole. The other end of the rotating shaft 32123 passes through the second shaft hole.

[0085] like Figure 13 and Figure 14 In some embodiments, the arrangement space is configured as a U-shaped groove with the opening facing upwards or downwards, which facilitates the positioning of the roller 32122. Specifically, the first rolling support can be located behind the second rolling support, and the extension frame 3202 of the first rolling support is located below the corresponding roller 32122. The arrangement space of the first rolling support is configured as an upward-opening U-shaped groove. The extension frame 3202 of the second rolling support is located above the corresponding roller 32122, and the arrangement space of the first rolling support is configured as a downward-opening U-shaped groove.

[0086] In addition, such as Figure 8 The surface corresponding to the roller 32122 within the arrangement space can be provided with support ribs 3203, which separate the roller 32122 from the corresponding surface. The surface corresponding to the roller 32122 within the arrangement space is designed with two vertical ribs to prevent the roller 32122 from rubbing against the entire sidewall surface when it shifts axially, thus preventing the roller 32122 from rolling unevenly.

[0087] Among them, such as Figure 14The supporting body 321 also includes a guide rail limiting structure 3213, which is disposed opposite to the adjacent rolling support 3212 and encloses an installation space for the guide rail 20 to pass through. Specifically, in the projection along the front-to-back direction, the vertical distance between the end of the guide rail limiting structure 3213 away from the main body 3211 and the roller frame 32121 of the corresponding rolling support 3212 is less than the vertical height of the corresponding guide rail. The guide rail limiting structure 3213 and the roller frame 32121 can be used to limit the guide rail, preventing it from detaching from the installation space in the left-to-right direction.

[0088] The first rolling support can be located behind the second rolling support. The extension frame 3202 of the first rolling support is located below the corresponding roller 32122. The arrangement space of the first rolling support is a U-shaped groove with an upward opening. The extension frame 3202 of the second rolling support is located above the corresponding roller 32122. The arrangement space of the first rolling support is a U-shaped groove with a downward opening. The guide rail limiting structure 3213 may include a first limiting structure and a second limiting structure, which are diagonally distributed. The first limiting structure is located above the first rolling support and is a U-shaped groove with a downward opening. The first limiting structure and the first rolling support enclose an installation space for the guide rail 20 to pass through. The second limiting structure is located below the second rolling support and is a U-shaped groove with an upward opening. The second limiting structure and the second rolling support enclose an installation space for the guide rail 20 to pass through.

[0089] Optionally, the support body 321 further includes a limiting rib 3214, which is disposed between the first rolling support and the second rolling support.

[0090] In related technologies, the supporting device 30 is commonly prone to being pulled out, causing it to damage tableware or causing the tableware loaded on it to fall and be destroyed. To address this issue, a limiting rib 3214 is designed on the support body 321 to prevent the supporting device 30 from being pulled out. This limiting rib 3214 is a trapezoidal (or columnar) structure extending from the support body 321, with a hollowed-out bottom (to prevent water and residue accumulation). It has a certain length and strength, and when the user pulls out the supporting device 30 (lifting it diagonally upwards), the limiting rib 3214 abuts against the metal guide rail, thus preventing the supporting device 30 from detaching.

[0091] like Figure 15 and Figure 16The bearing device 30 clamps the guide rail structure, and the bracket assembly 33 clamps the guide rail 20 and slides on it through the left and right side support assemblies 32. The diagonal rollers support the bearing frame 31 and slide on it. The rollers 32122 are assembled in the placement space, and there is a certain axial gap between the two sides and the side wall of the placement space. When the rollers 32122 roll against the guide rail, the axial movement keeps the rollers 32122 in a matching state with the guide rail surface, preventing the rollers 32122 from getting stuck with the guide rail when the bearing device 30 shakes left and right. Another diagonal guide rail limiting structure 3213 plays a limiting role. It is a U-shaped structure extending from the support body 321, with the opening facing the guide rail. The inner side of the U-shaped structure is similar to the outer contour of the metal guide rail and leaves a certain gap (which determines the lifting angle of the bearing device 30). The vertical gap between the outer side of the placement space where the rollers 32122 are installed (the side away from the main body) and the outer side of the guide rail limiting structure 3213 is smaller than the vertical width of the guide rail, and they clamp the guide rail together. To prevent the guide rail from coming off the left and right support components 32.

[0092] The movable bracket 332, integrated with the bottom mesh, provides ample loading space for the upper basket. The loading space of the support device 30 can be flexibly selected to meet the needs of various usage scenarios. The movable bracket 332 slides smoothly, enhancing the user experience.
