[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0032] See also Figure 1 and Figure 2 , Figure 1 A structural diagram of a cutlery tray assembly of a dishwasher according to an embodiment of the present application is shown. Figure 2 Shows Figure 1 An exploded structural diagram of two cutlery tray bodies 10 in the structure shown. An embodiment of the present application provides a cutlery tray assembly for a dishwasher, the cutlery tray assembly for a dishwasher comprising: two cutlery tray bodies 10. Each cutlery tray body 10 comprises a tray shell 11, and each tray shell 11 comprises a butt joint side 111. Each butt joint side 111 is provided with at least one connecting portion 112, and the connecting portions 112 of the two butt joint side 111 are detachably connected to each other.

[0033] Compared with the cutlery tray assembly in the related art in which the tray shell 11 is set as an integral structure, the above-mentioned cutlery tray assembly of the dishwasher includes two cutlery tray bodies 10, which are formed by splicing and combining the two cutlery tray bodies 10 through the butt joint sides 111 of their respective tray shells 11. In this way, the volume size of a single tray shell 11 is relatively reduced, so that the volume size of the molding mold used to produce the tray shell 11 can be reduced, thereby greatly reducing the mold cost, that is, reducing the production cost.

[0034] See also Figure 1 and Figure 2In some embodiments, the outer shape and volume size of the tray shells 11 of the two cutlery tray bodies 10 are exactly the same. In this way, the tray shells 11 of the two cutlery tray bodies 10 are produced using the same molding mold, so there is no need to design two molding molds with different shapes and volume sizes, which reduces the mold cost. In addition, when the two cutlery tray bodies 10 are assembled and connected, one of the tray shells 11 is placed horizontally, and the other tray shell 11 is rotated 180 degrees in the horizontal direction, so that the connecting parts 112 on the two docking sides 111 are aligned with each other, and they can be assembled and fixed together; the cutlery tray assembly has a simple structure and is easy to install. The entire cutlery tray assembly is divided into two cutlery tray bodies 10 with exactly the same appearance and size. The volume size of a single part is greatly reduced, thereby greatly reducing the mold volume and saving mold costs.

[0035] Of course, as some optional solutions, the outer shapes and volume dimensions of the tray shells 11 of the two cutlery tray bodies 10 can also be different from each other, so that the tray shells 11 of the two cutlery tray bodies 10 are respectively processed by two molding molds with different shapes and volume dimensions.

[0036] See also Figure 1 and Figure 2 In one embodiment, at least two connecting parts 112 are provided on each butt joint side 111, and each connecting part 112 on one butt joint side 111 is provided correspondingly and detachably connected to each connecting part 112 on another butt joint side 111. In this way, the more connecting parts 112 there are on each butt joint side 111, the more stability the two cutlery tray bodies 10 can be assembled together.

[0037] It should be noted that the connection parts 112 of the two docking sides 111 can be detachably connected in many ways, including but not limited to snap-on connection, connection with various fasteners such as screws, pins, rivets, etc., which can be flexibly adjusted and set according to actual needs and are not limited here.

[0038] See also Figure 1 and Figure 2In one embodiment, the connection portion 112 on one of the butt joint sides 111 includes a slot 1122 and / or a stopper hook 1121, and the connection portion 112 on the other butt joint side 111 includes a stopper hook 1121 and / or a slot 1122. In addition, for the two butt joint sides 111, the stopper hook 1121 on one of the two butt joint sides 111 can be detachably connected and fixed to the slot 1122 on the other of the two butt joint sides 111. In this way, when the two cutlery tray bodies 10 are assembled, the stopper hook 1121 on one of the butt joint sides 111 is detachably connected and fixed to the slot 1122, which not only enables the two cutlery tray bodies 10 to be quickly assembled together, but also facilitates installation, improves assembly efficiency, and the overall structure after assembly is simple and firm.

[0039] In this embodiment, when at least two connecting parts 112 are provided on the butt joint side 111, half of the connecting parts 112 are provided as slots 1122, and the other half of the connecting parts 112 are provided as stop hooks 1121, so that the two tray shells 11 have the same shape and size, that is, the two cutlery tray bodies 10 have the same shape and size, and can be processed and produced using the same molding die, thereby reducing the die cost. Specifically, for example, two slots 1122 and two stop hooks 1121 are provided on the butt joint side 111 of the two tray shells 11.

[0040] See also Figures 3 to 5 , Figure 3 Shows Figure 2 Enlarged structural diagram at A. Figure 4 Shows Figure 2 Enlarged structural diagram at B. Figure 5 Shows Figure 1A partial enlarged view of the structure shown. In one embodiment, the limiting hook 1121 includes a connecting arm 11211 and a stopper 11212. One end of the connecting arm 11211 is connected to the docking side 111, and the other end of the connecting arm 11211 is connected to the stopper 11212. The card slot 1122 includes a plug hole 11221 and a limiting groove 11222 that penetrates the docking side 111. The limiting groove 11222 is connected to the plug hole 11221, and a limiting protrusion 11223 is provided on the groove wall of the limiting groove 11222, and the stopper 11212 can pass through the plug hole 11221. The connecting arm 11211 can move between the limiting groove 11222 and the plug hole 11221, so that the limiting hook 1121 can switch between the locking position and the unlocking position at will. When the limiting hook 1121 is in the locked position, the connecting arm 11211 is inserted into the limiting groove 11222 and abuts against the limiting protrusion 11223, and the stopper 11212 abuts against the abutting side edge for positioning; when the limiting hook 1121 is in the unlocked position, the connecting arm 11211 is inserted into the insertion hole 11221. In this way, when the limiting hook 1121 is inserted into the slot 1122 to connect the two tray shells 11, the stopper 11212 of the limiting hook 1121 is first aligned with the insertion hole 11221 so that the stopper 11212 is inserted into the insertion hole 11221, and then the tray shell 11 is pushed so that the connecting arm 11211 passes through the limiting protrusion 11223 and enters the limiting groove 11222, that is, the limiting hook 1121 is moved from the unlocked position to the locked position, and the connecting arm 11211 and the limiting protrusion 112 23 is abutted and positioned, and the stopper 11212 is abutted and positioned with the abutting side, so that the two tray shells 11 can be connected and fixed; when the two tray shells 11 need to be disassembled, the tray shells 11 are pushed in opposite directions so that the connecting arms 11211 pass through the limiting protrusions 11223 and enter into the insertion holes 11221, that is, the limiting hooks 1121 are moved from the locked position to the unlocked position, and the stopper 11212 is located in a position corresponding to the insertion holes 11221, so that the two tray shells 11 can be separated from each other.

[0041] See also Figures 3 to 5 In some embodiments, the axial cross-sectional area of ​​the connecting arm 11211 is smaller than the axial cross-sectional area of ​​the stopper 11212, so that the connecting arm 11211 can move smoothly through the limiting groove 11222, while the stopper 11212 cannot pass through the limiting groove 11222. In this way, when the connecting arm 11211 is inserted into the limiting groove 11222, it plays a role in abutting and positioning with the docking side 111.

[0042] See also Figures 3 to 5 In some embodiments, the limiting protrusion 11223 and / or the connecting arm 11211 include but are not limited to elastic members. The outer wall of the limiting protrusion 11223 is in an arc shape. In this way, the connecting arm 11211 can be smoothly switched between the locking position and the unlocking position to avoid jamming and noise defects.

[0043] It should be noted that the "limiting hook 1121 and the limiting protrusion 11223" can be "a part of the abutting side", that is, the "limiting hook 1121 and the limiting protrusion 11223" and the "other parts of the abutting side" are manufactured as one piece; or it can be an independent component separable from the "other parts of the abutting side", that is, the "limiting hook 1121 and the limiting protrusion 11223" can be manufactured independently and then combined with the "other parts of the abutting side" into a whole.

[0044] See also Figures 3 to 5 In some embodiments, a groove 11213 is formed on the connecting arm 11211. The groove 11213 specifically extends from the abutting side to the connecting arm 11211, and extends from one end of the connecting arm 11211 to the other end of the connecting arm 11211. In this way, since the connecting arm 11211 is provided with the groove 11213, the connecting arm 11211 is easily deformed when subjected to force during the process of switching positions between the insertion hole 11221 and the limiting groove 11222, so that the connecting arm 11211 can switch smoothly and arbitrarily between the locked position and the unlocked position, avoiding the occurrence of jamming and noise defects.

[0045] See also Figures 3 to 5 In some embodiments, the limiting groove 11222 extends in the horizontal direction, which is parallel to the bottom wall of the tray housing 11. In addition, the insertion hole 11221 is, for example, a circular hole, and the diameter of the circular hole is larger than the distance between the relative groove walls of the limiting groove 11222. The bottom wall surface of the limiting groove 11222 is tangent to the hole wall of the circular hole, so that the connecting arm 11211 can move and switch from the insertion hole 11221 to the limiting groove 11222 more smoothly, which can reduce the jamming noise defect.

[0046] See also Figure 1 In one embodiment, the cutlery tray assembly further includes a tray bracket 20. The tray bracket 20 is connected to the two cutlery tray bodies 10 respectively, and the tray bracket 20 is arranged around the circumference of the two cutlery tray bodies 10. In this way, assembling the two cutlery tray bodies 10 onto the tray bracket 20 can make the overall structure firm and reliable.

[0047] See also Figure 1 and Figure 2 In one embodiment, the cutlery tray body 10 further includes a cutlery support 12 disposed inside the tray shell 11. The tray shell 11 and the cutlery support 12 are integrally formed. The cutlery support 12 can be used to place various light and short cutlery such as knives, forks, spoons, chopsticks, and saucers. The cutlery support 12 and the tray shell 11 are integrally formed using a molding mold, thereby improving production efficiency and being suitable for mass production.

[0048] The tray shell 11 and the tableware support 12 include but are not limited to being integrally formed by injection molding, and of course, may also be integrally formed by die-casting, integrally formed by die-cutting, or formed by 3D printing.

[0049] In this embodiment, the cutlery tray bodies 10 have the same shape and size and are processed by the same molding die. Thus, the two cutlery tray bodies 10 do not need to be processed by two different types of molding dies, thereby reducing the mold cost and the production cost.

[0050] In some embodiments, the cutlery tray body 10 can be configured as a metal part that is resistant to high temperatures, has a long service life, and is not easily damaged; or it can be configured as a plastic part that is resistant to high temperatures, is light in weight, and has a low cost.

[0051] See also Figure 1 , Figure 2 and Figure 6 In one embodiment, the cutlery tray assembly further includes at least one handle assembly 30. The handle assembly 30 is detachably disposed on the outer wall of the cutlery tray body 10. In this way, the handle assembly 30 can facilitate the taking of the cutlery tray body 10 and facilitate the loading and unloading of the tray body. In addition, the handle assembly 30 can be installed and removed according to actual needs.

[0052] See also Figure 1 , Figure 2 and Figure 6 In some embodiments, the shape and size of the handle assembly 30 are the same as the shape and size of the handles of the upper and lower basket assemblies. In this way, the handle assembly 30 can be shared with the handles of the upper and lower basket assemblies, and the parts have good commonality. In addition, after the dishwasher door is opened, it can be observed that the upper and lower basket assemblies and the cutlery tray assembly use the same handle, and the overall appearance of the handles of the upper and lower basket assemblies and the cutlery tray assembly is consistent, which is more beautiful.

[0053] See also Figure 1 , Figure 2 and Figure 6 In one embodiment, at least one end of the cutlery tray assembly is provided with a slot 40, and the handle assembly 30 is detachably disposed in the slot 40. In this way, the handle assembly 30 is detachably disposed on the outer wall of the cutlery tray body 10 by being inserted into the slot 40, and is convenient for disassembly and assembly. Specifically, the handle assembly 30 can be inserted downward into the slot 40; conversely, the handle assembly 30 can be taken out of the cutlery tray assembly.

[0054] See also Figure 1 , Figure 2 and Figure 6In some embodiments, two opposite ends of the cutlery tray assembly are provided with slots 40 . Two handle assemblies 30 are provided, and each handle assembly 30 is correspondingly inserted and installed in each slot 40 .

[0055] The end of each cutlery tray body 10 is provided with a recess 41, and the recesses 41 at the ends of the two cutlery tray bodies 10 are spliced ​​together to form a slot 40. In this way, the slot 40 is located at the splicing position of the ends of the two cutlery tray bodies 10, and the handle assembly 30 acts on the splicing position of the ends of the two cutlery tray bodies 10, so that the two cutlery tray bodies 10 can be stably extracted and moved.

[0056] See also Figure 1 , Figure 2 and Figure 6 In some embodiments, the tray support 20 includes at least one fixing rod 21. The fixing rod 21 abuts against a side of the handle assembly 30 away from the cutlery tray body 10. The cutlery tray body 10 abuts against a side of the handle assembly 30 and is provided with a flange 13. The flange 13 abuts against the top of the cutlery tray body 10. In this way, the handle assembly 30 is installed in the slot 40, and the flange 13 abuts against the top of the cutlery tray body 10, so that the handle assembly 30 can be stably installed in the slot 40.

[0057] In one embodiment, a dishwasher is provided, comprising the cutlery tray assembly of the dishwasher according to any one of the above embodiments.

[0058] Compared with the related art in which the tray shell 11 of the cutlery tray assembly is set as an integral structure, the above-mentioned dishwasher includes two cutlery tray bodies 10, and the two cutlery tray bodies 10 are formed by splicing and combining with each other through the butt joint side edges 111 of their respective tray shells 11. In this way, the volume size of a single tray shell 11 is relatively reduced, so that the volume size of the molding mold used to produce the tray shell 11 can be reduced, thereby greatly reducing the mold cost, that is, reducing the production cost.
