Detailed Implementation

[0041] Currently, dishwashers typically use either one-piece or multi-functional tray components (such as cutlery trays) or adjustable bottom mesh. One-piece trays have poor compatibility with the size of the tableware placed on or below them, while multi-functional trays (with adjustable bottom mesh) offer limited improvement in the utilization of the dishwasher's internal space and do not slide smoothly.

[0042] To address the pain points mentioned above regarding usage and demand, this utility model proposes a carrying tray assembly, including a fixed bracket in the middle and movable brackets on the left and / or right sides. The fixed bracket is recessed relative to the movable bracket, and the movable bracket can slide in the left and right direction and can slide above the fixed bracket. Specifically, the carrying tray assembly mainly includes a carrying frame, a surrounding frame, a support component, a movable bracket, a fixed bracket, a handle, and other parts. Each component is assembled onto the carrying frame via slots and buckles. The carrying frame also includes guide strips (e.g., guide wires) in the left and right direction, and the movable bracket can slide left and right along the guide strips. The recessed fixed bracket provides a larger loading space for the carrying tray assembly. When the dish rack needs to load large tableware, the movable brackets on the left and right sides can be slid towards the middle, 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.

[0043] This utility model relates to the field of household appliance technology, and in particular to a (non-integral) support tray assembly with a movable bottom mesh. The bottom mesh of the tray, as a support for cutlery, together with the upper dish rack, determines the space utilization rate in the middle and upper part of the dishwasher's inner cavity.

[0044] 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.

[0045] like Figures 1 to 5 The carrying tray assembly 20 according to an embodiment of the present invention includes: a carrying frame 21 and a fixed bracket 22. The carrying frame 21 provides support for the fixed bracket 22 to improve the stability of the fixed bracket 22 and reduce or avoid twisting and deformation of the fixed bracket 22 during use. The fixed bracket 22 can be used to support cutlery such as knives and forks.

[0046] The supporting frame 21 has a first limiting part 201. A fixed bracket 22 is connected to the supporting frame 21 and has a second limiting part 202, which corresponds to the first limiting part 201. The second limiting part 202 and the first limiting part 201 cooperate to limit the fixed bracket 22 in the left-right direction. The cooperation of the second limiting part 202 and the first limiting part 201 can limit the fixed bracket 22 in the left-right direction. During use, if the fixed bracket 22 twists in the front-back direction, the cooperation of the first limiting part 201 and the second limiting part 202 can prevent this twisting and maintain the structural stability of the fixed bracket 22.

[0047] According to the embodiment of the present utility model, the support tray assembly 20 can improve the limiting stability of the fixed bracket 22 and the support frame 21 in the left and right directions, thereby improving the stability of the fixed bracket 22, avoiding or reducing the shaking of the fixed bracket 22, and maintaining the stability of the cutlery such as knives and forks placed on the fixed bracket 22.

[0048] like Figures 1 to 5 In some embodiments, one of the first limiting portion 201 and the second limiting portion 202 includes a limiting strip extending in a vertical direction, and the other of the first limiting portion 201 and the second limiting portion 202 includes a limiting groove extending in a vertical direction, with the limiting strip positioned between the left and right sides of the limiting groove. This includes, but is not limited to:

[0049] The first limiting part 201 includes a limiting strip extending in the vertical direction, and the second limiting part 202 includes a limiting groove extending in the vertical direction. The limiting strip is limited between the left side and the right side of the limiting groove.

[0050] Alternatively, the second limiting part 202 includes a limiting strip extending in the vertical direction, and the first limiting part 201 includes a limiting groove extending in the vertical direction, with the limiting strip positioned between the left and right sides of the limiting groove.

[0051] Alternatively, the first limiting part 201 includes a limiting strip and a limiting groove extending in the vertical direction, and the second limiting part 202 includes a limiting groove and a limiting strip extending in the vertical direction. The limiting strip in the first limiting part 201 is located between the left and right sides of the limiting groove in the second limiting part 202, and the limiting strip in the second limiting part 202 is located between the left and right sides of the limiting groove in the first limiting part 201.

[0052] By using the combination of the limiting strip and the limiting groove extending in the vertical direction, not only can the movement of the fixed bracket 22 relative to the bearing frame 21 in the left and right directions be restricted, thus maintaining the positional stability of the fixed bracket 22, but also the limiting strip and the limiting groove are both set to extend in the vertical direction. When the fixed bracket 22 is present and twists about the axis in the front and back directions, the left and right sides of the limiting groove can restrict the twisting of the limiting strip, thereby maintaining the stability of the fixed bracket 22 on the bearing frame 21 and improving the stability of the bearing pallet assembly 20.

[0053] In addition, the fixed bracket 22 in this utility model can be configured to be installed on the bearing frame 21 in the vertical direction. By setting the limiting strip and the limiting groove as long strips extending in the vertical direction, it is convenient to assemble the limiting strip and the limiting groove, and to assemble the fixed bracket 22 onto the bearing frame 21.

[0054] Optionally, the limiting strip is inclined towards the inner side of the supporting frame 21 in a top-to-bottom direction. This further improves the stability of the fit between the limiting strip and the limiting groove, achieving stable assembly of the fixed bracket 22. In addition, in conjunction with the above, when the fixed bracket 22 is assembled in a top-to-bottom direction, the fit strength and stability of the limiting strip and the limiting groove gradually increase during the top-to-bottom assembly process, thereby effectively improving the fit stability between the fixed bracket 22 and the supporting frame 21 and facilitating assembly.

[0055] Alternatively, the limiting groove can be set to be inclined towards the middle of the fixed bracket 22 in the downward direction. Furthermore, the angle at which the limiting groove is inclined towards the middle of the fixed bracket 22 in the downward direction can be set to be the same as the inclination angle of the limiting strip, so as to further improve the stability of the fit between the limiting strip and the limiting groove. Alternatively, the angle at which the limiting groove is inclined towards the middle of the fixed bracket 22 in the downward direction can be set to be the same as, similar to, or different from the inclination angle of the limiting strip.

[0056] Optionally, the angle at which the limiting strip is inclined toward the inner side of the bearing frame 21 in the downward direction is greater than or equal to 3° and less than or equal to 30°. For example, the inclination angle can be set to 3°, 4.5°, 12°, 18°, 24° or 30°, etc., wherein the bearing frame 21 can be configured as a frame shape extending in the left-right direction and the front-back direction, and the axis of the bearing frame 21 can be configured to extend in the up-down direction, and the aforementioned included angle can be set as the angle between the axis of the limiting strip and the axis of the bearing frame 21; in addition, during the use of the bearing frame 21, it can be configured to be placed horizontally, and the aforementioned included angle can be set as the angle between the limiting strip and the up-down direction.

[0057] In conjunction with the foregoing, in some embodiments of this utility model, the fixing bracket 22 is fixedly installed on the bearing frame 21, and the corresponding assembly wire has a concave structure. A short wire is designed in the inner part of the concave wire, which, together with the wires on both sides of the concave shape, restricts the left-right swaying of the fixing piece. To facilitate the assembly of the fixing piece, the short wire in the middle is angled outwards at a 3-30° angle.

[0058] Optionally, in other embodiments, one of the first limiting part 201 and the second limiting part 202 includes at least two limiting strips distributed along the vertical and / or horizontal directions, and the other of the first limiting part 201 and the second limiting part 202 includes a limiting groove corresponding to the limiting strip; or, one of the first limiting part 201 and the second limiting part 202 includes at least two limiting grooves distributed along the vertical and / or horizontal directions, and the other of the first limiting part 201 and the second limiting part 202 includes a limiting strip corresponding to the limiting groove. By providing multiple limiting grooves and / or multiple limiting strips, the torsion of the fixed bracket 22 can be further restricted, and the stability of the mating structure between the first limiting part 201 and the second limiting part 202 can be further improved. These embodiments include, but are not limited to, the following:

[0059] For example, the first limiting part 201 includes at least two limiting strips distributed in the vertical direction, and the other of the second limiting parts 202 includes a limiting groove corresponding to a limiting strip. The limiting groove may include one corresponding to the at least two limiting strips; or the limiting groove may include at least two corresponding to the at least two limiting strips. The limiting strip is positioned between the left and right sides of the corresponding limiting groove.

[0060] In example two, the first limiting part 201 includes at least two limiting strips distributed in the left-right direction, and another of the second limiting parts 202 includes a limiting groove corresponding to a limiting strip. The limiting groove may include at least two grooves corresponding to at least two limiting strips. The limiting strip is positioned between the left and right sides of the corresponding limiting groove.

[0061] Example 3: The first limiting part 201 includes at least two limiting strips distributed along the vertical and horizontal directions. Each set of limiting strips includes at least one limiting strip distributed along the vertical direction, and each set of limiting strips is provided with at least one limiting groove. The limiting strip is located between the left and right sides of the corresponding limiting groove.

[0062] Example 4: The first limiting part 201 includes at least two limiting grooves distributed along the vertical direction, and another of the second limiting parts 202 includes a limiting strip corresponding to a limiting groove. The limiting strip may include one corresponding to the at least two limiting grooves; or the limiting strip may include at least two corresponding to the at least two limiting grooves. The limiting strip is positioned between the left and right sides of the corresponding limiting groove.

[0063] Example 5: The first limiting part 201 includes at least two limiting grooves distributed in the left-right direction, and another of the second limiting parts 202 includes a limiting strip corresponding to a limiting groove. The limiting strip may include at least two corresponding to at least two limiting grooves. The limiting strip is located between the left and right sides of the corresponding limiting groove.

[0064] Example 6: The first limiting part 201 includes at least two limiting grooves distributed along the vertical and horizontal directions. Each set of limiting grooves includes at least one limiting groove distributed along the vertical direction, and each set of limiting grooves is provided with at least one limiting strip. The limiting strip is located between the left and right sides of the corresponding limiting groove.

[0065] like Figures 2 to 5 In some embodiments of this utility model, the supporting frame 21 includes a first frame portion 211 and a second frame portion 212, which are spaced apart in the front-to-back direction. A fixed bracket is positioned between the first frame portion 211 and the second frame portion 212. The front end of the fixed bracket can be connected to the first frame portion 211, and the rear end of the fixed bracket can be connected to the second frame portion 212. The cooperation of the first frame portion 211 and the second frame portion 212 can be used to achieve stable positioning of the fixed bracket, improve the stability and load-bearing capacity of the fixed bracket, and limit the torsion and movement of the fixed bracket.

[0066] The first limiting part 201 may include a limiting strip disposed on the first frame part 211, and the second limiting part 202 may include a limiting groove disposed on the front end face of the supporting frame 21. Alternatively, the first limiting part 201 may also include a limiting strip disposed on the second frame part 212, and the second limiting part 202 may also include a limiting groove disposed on the rear end face of the supporting frame 21. Furthermore, the first limiting part 201 may include both the limiting strip disposed on the first frame part 211 and the limiting strip disposed on the second frame part 212, and the second limiting part 202 may include both the limiting groove disposed on the front end face and the limiting groove disposed on the rear end face of the supporting frame 21. By placing the limiting strip on the front and / or rear end of the supporting frame 21 and the limiting groove on the front end face and / or rear end face of the fixing bracket, the assembly of the fixing bracket can be facilitated. Combined with the positioning structure between the fixing bracket and the supporting frame 21, the assembly efficiency of the fixing bracket and the stability of its connection with the supporting frame 21 can be improved.

[0067] To further improve the installation stability of the fixed bracket 22, the fixed bracket 22 includes a bracket body 221, a first positioning part 222, and a second positioning part 223. The bracket body 221 is positioned between a first frame part 211 and a second frame part 212. The first positioning part 222 is connected to the first frame part 211, and the second positioning part 223 is connected to the second frame part 212. This allows for stable installation of the fixed bracket 22, improving its stability and load-bearing capacity.

[0068] The connection method between the first positioning part 222 and the first frame part 211 may include, but is not limited to, the following embodiments.

[0069] like Figure 3 The first positioning part 222 includes a first fastening part 2221, which connects to the bracket body 221. A first fastening groove with an opening facing downwards is formed between the first fastening part 2221 and the bracket body 221, and the first frame part 211 passes through the first fastening groove. This allows the first positioning part 222 to be quickly fastened to the first frame part 211, improving the connection efficiency and stability between the first positioning part 222 and the first frame part 211.

[0070] In addition, the first positioning part 222 may also include a second fastening part 2222, which is lower than and spaced apart from the first fastening part 2221. The stability of the connection structure between the first positioning part 222 and the first frame part 211 can be further improved by using the second fastening part 2222.

[0071] The second fastener 2222 can be offset from the first fastener 2221 in the left-right direction to improve the assembly efficiency of the first positioning part 222 and the first frame part 211, and realize the rapid assembly of the first positioning part 222 and the first frame part 211.

[0072] In addition, the thickness of the first snap-fit ​​2221 can be smaller than that of the second snap-fit ​​2222 to facilitate the deformation of the first snap-fit ​​2221, so as to facilitate the quick assembly of the first snap-fit ​​2221 and the first frame part 211. The thicker second snap-fit ​​2222 can improve the strength of the connection structure between the first positioning part 222 and the first frame part 211.

[0073] Furthermore, the width of the first latch 2221 in the left-right direction is greater than the width of the second latch 2222 in the left-right direction. This improves the assembly efficiency of the first positioning part 222 and the first frame part 211, and enhances the stability after assembly.

[0074] like Figure 3 The first positioning part 222 may further include a first hook 2223 and a second hook 2224. The first hook 2223 and the second hook 2224 are hung on the first frame part 211. The first hook 2223 and the second hook 2224 are distributed in the left-right direction, and a second limiting part 202 is provided between the first hook 2223 and the second hook 2224. In addition, the first frame part 211 is provided with a first limiting part 201 corresponding to the second limiting part 202. This can further improve the stability of the connection structure between the first positioning part 222 and the first frame part 211, and can also improve the cooperation efficiency and stability between the first limiting part 201 and the second limiting part 202 by utilizing the first hook 2223 and the second hook 2224.

[0075] The connection method between the second positioning part 223 and the second frame part 212 may include, but is not limited to, the following embodiments.

[0076] like Figure 5 The second positioning part 223 may have a second buckle groove with an opening facing away from the bracket body 221 in the front-back direction. The second frame part 212 passes through the second buckle groove. During the assembly process, the second frame part 212 can be inserted into the second buckle groove along the opening direction of the second buckle groove. Then, by rotating the fixed bracket 22, the first positioning part 222 and the first frame part 211 are assembled together, thereby improving the connection efficiency and stability between the fixed bracket 22 and the load-bearing frame 21.

[0077] Specifically, the second positioning part 223 may include a third fastener 2231 and a fourth fastener 2232, which are distributed along the vertical direction and on both sides of the second frame part 212 along the vertical direction.

[0078] Optionally, the second positioning part 223 may include at least two distributed along the left-right direction, and a second limiting part 202 is provided between adjacent second positioning parts 223. Correspondingly, the second frame part 212 is provided with a first limiting part 201 corresponding to the second limiting part 202. This can further improve the stability of the connection structure between the second positioning part 223 and the second frame part 212.

[0079] In conjunction with the foregoing embodiments, the fixing bracket 22 and the supporting frame 21 can be configured as an assembly and fixing structure with one insertion and one snap-fit: the second positioning part 223 is provided with a horizontal snap-fit, and the first positioning part 222 is provided with a vertical snap-fit. The bracket is connected to the supporting frame 21 through the horizontal and vertical snap-fits, making it less prone to detachment and easy to assemble. During assembly, after the second positioning part 223 is snap-fitted to the supporting frame 21, the fixing bracket 22 can be flipped over to snap-fit ​​the first positioning part 222 to the supporting frame 21.

[0080] Furthermore, the first positioning part 222 adopts a double-offset buckle structure: the first buckle position 2221 and the second buckle position 2222 of the first positioning part 222 are arranged in a staggered manner. The first positioning part 222 includes two sets located on the same side of the fixed bracket 22. A set is formed by the wider first buckle position 2221 and the narrower second buckle position 2222. The wider first buckle position 2221 is an upper buckle with a thinner wall thickness, making it more easily deformed. The narrower second buckle position 2222 is a convex structure with a smaller and thicker size, resulting in greater strength. The staggered buckles have different strengths, facilitating assembly. At the same time, the staggered buckles have stronger torsional resistance than the non-staggered buckles.

[0081] like Figure 3 In some embodiments, the first frame portion 211 may include a first support strip 2111 and a first positioning strip 2112. The first positioning strip 2112 is connected to the left and right ends of the first support strip 2111 and extends upward. The first positioning portion 222 is connected to the first support strip 2111 and is confined between the first positioning strips 2112 at both ends of the first support strip 2111. The first support strip 2111 can be used to achieve a stable and rapid connection with the fixed bracket 22, and the first positioning strip 2112 can be used to limit the left and right movement of the first positioning portion 222, thereby improving the stability of the connection structure between the fixed bracket 22 and the first frame portion 211.

[0082] like Figure 5In some embodiments, the second frame portion 212 may include a second support strip 2121 and a second positioning strip 2122. The second positioning strip 2122 is connected to the left and right ends of the second support strip 2121 and extends upward. The second positioning portion 223 is connected to the second support strip 2121 and is confined between the second positioning strips 2122 at both ends of the second support strip 2121. The second support strip 2121 can be used to achieve a stable and rapid connection with the fixed bracket 22, and the second positioning strip 2122 can be used to limit the second positioning portion 223 to move in the left and right directions, thereby improving the stability of the connection structure between the fixed bracket 22 and the second frame portion 212.

[0083] like Figures 6 to 10 In some embodiments, the fixing bracket 22 includes: a plurality of transverse ribs 2211, a plurality of longitudinal ribs 2212, and a plurality of toothed strips.
