[0059] Embodiment one

[0060] As Figures 1-4As shown, in one embodiment of the present application, referring to Fig. 1, a utensil tray 1 is provided, which is suitable for being arranged in a dishwasher, and is usually arranged on the top of a washing cavity 4 of the dishwasher. The utensil tray 1 is mainly used for carrying knives, forks, spoons, spatulas and other tableware. The utensil tray 1 is particularly suitable for being used in a dishwasher with three or more layers of plastic integrated utensil trays 1.

[0061] Specifically, referring to Fig. 2, the utensil tray 1 comprises a bottom 11 and a surrounding frame 12, which is arranged around the bottom 11 and cooperates with the bottom 11 to form a mounting cavity 20 for accommodating tableware. The height of the surrounding frame 12 is greater than the thickness of the bottom 11, and the upper end surface of the surrounding frame 12 is located above the upper surface of the bottom 11, so that the inner wall of the surrounding frame 12 and the upper surface of the bottom 11 form the mounting cavity 20. The tableware is placed in the mounting cavity 20, and the surrounding frame 12 plays a role in blocking the tableware to avoid falling out of the mounting cavity 20. Further, the surrounding frame 12 is provided with an avoiding groove 121 for avoiding the spray arm 2 of the dishwasher. The avoiding groove 121 is arranged on the upper end surface of the surrounding frame to avoid the spray arm 2 on the top of the washing cavity 4 of the dishwasher.

[0062] When the utensil tray 1 is pushed into or out of the washing cavity 4 of the dishwasher, the spray arm 2 passes through the avoiding groove 121, thereby avoiding the interference between the spray arm 2 and the utensil tray 1. At the same time, the arrangement of the avoiding groove 121 shortens the distance between the utensil tray 1 and the top surface of the washing cavity 4, thereby making the utensil tray 1 have a larger spatial distance with the bowl basket 3 located below the utensil tray 1, so that the bowl basket 3 has a larger space for carrying tableware, and the washing cavity 4 can accommodate more tableware, greatly improving the space utilization of the washing cavity 4 and the loading capacity of the dishwasher.

[0063] In the embodiment, the depth of the avoiding groove 121 of the utensil tray 1 is t1, the height of the rotating space of the spray arm 2 is h, and the depth of the mounting cavity 20 is t2. t1, h and t2 satisfy the following relationship: h≤t1≤t2. Specifically, the depth t1 of the avoiding groove 121 is greater than or equal to the height h of the rotating space of the spray arm 2, so that the interference between the spray arm 2 and the surrounding frame 12 of the utensil tray 1 can be completely avoided. At the same time, the depth t1 of the avoiding groove 121 is less than or equal to the depth t2 of the mounting cavity 20, so as to ensure that the bottom 11 does not interfere with the spray arm 2.

[0064] In the embodiment, t1 and t2 also satisfy the following relationship: t2 / 3≤t1≤t2 / 2. Specifically, the depth t1 of the avoiding groove 121 is set in the above range, which can ensure that the knife and fork tray 1 has good structural strength and can stably support tableware without interfering with the spray arm 2; if the depth t1 of the avoiding groove 121 is too small, on the one hand, the overall material accumulation is too much, which increases the manufacturing cost, and on the other hand, the interference problem between the spray arm 2 and the avoiding groove 121 is avoided; if the depth t1 of the avoiding groove 121 is too large, the depth of the avoiding groove 121 is too deep, and the overall structural strength of the knife and fork tray 1 is weak, which is easy to damage.

[0065] In the embodiment, as shown in FIG. 2, the frame 12 has a handle portion 122 for a user to hold to push or pull the knife and fork tray 1 into or out of the washing cavity 4 of the dishwasher, and the handle portion 122 and the avoiding groove 121 are respectively arranged on the opposite two side walls of the frame 12. The user pushes or pulls the knife and fork tray 1 into or out of the washing cavity 4 of the dishwasher through the handle portion 122, which is simple and convenient to operate; in specific use, the end of the frame 12 with the avoiding groove 121 is inserted into the washing cavity 4, and then the entire knife and fork tray 1 is pushed into the washing cavity 4 through the handle portion 122 for washing; when the washing is completed, the entire knife and fork tray 1 is pulled out of the washing cavity 4 through the handle portion 122; in this process, since the avoiding groove 121 and the handle portion 122 are respectively arranged on the opposite two side walls of the frame 12, the spray arm 2 directly passes through the avoiding groove 121 to enter or move out of the mounting cavity 20 during the process of pushing or pulling the knife and fork tray 1 into or out of the washing cavity 4, which completely avoids the interference between the spray arm 2 and the frame 12.

[0066] Further, as shown in FIG. 2, Figure 2 of course, in other embodiments, the frame 12 can be a rectangular frame, a circular frame, a pentagonal frame, or other closed structure frame structure.

[0067] In the embodiment, the knife and fork tray 1 is a plastic tray. Specifically, the knife and fork tray 1 is made of plastic material, which is light in weight and easy to push and pull, and the user can operate more time-saving and labor-saving; specifically, the knife and fork tray 1 can be made by an integral injection molding process, which is simpler to make and has good structural reliability.

[0068] In the embodiment, as shown in FIG. 2, Figure 2 and Figure 3As shown, the outer wall of the frame 12 is provided with a roller shaft 123, and a roller 124 is sleeved on the roller shaft 123 and used to cooperate with the slide rail in the washing cavity 4 of the dishwasher. During the pushing and pulling of the fork tray 1, the fork tray 1 is pushed and pulled into and out of the washing cavity 4 of the dishwasher by the sliding of the roller 124 on the slide rail, which is more time-saving and labor-saving. More specifically, the roller 124 is sleeved on the roller shaft 123 and gap-fitted with the roller shaft 123, and the roller 124 rotates relative to the roller shaft 123, thereby achieving the sliding connection of the roller 124 and the slide rail, and making the pushing and pulling operation of the fork tray 1 more time-saving and labor-saving.

[0069] In the embodiment, in combination with Figure 3 and Figure 4 As shown, the end surface of the roller shaft 123 away from the frame 12 is provided with a vertical slot 1231. During the installation of the roller 124 on the roller shaft 123, the portions of the roller shaft 123 located on both sides of the vertical slot 1231 are retracted into the vertical slot 1231, and the outer diameter of the roller shaft 123 is reduced, thereby making the installation of the roller 124 more time-saving and labor-saving. In addition, when the roller 124 supports the slide rail, the portions of the roller shaft 123 located on both sides of the vertical slot 1231 can support the fork tray 1, and the support of the fork tray 1 is more secure and reliable. Compared with the general transverse slot structure, the structure can improve the overall bearing strength of the fork tray 1, meet the demand of loading heavy tableware, and also improve the use reliability of the fork tray 1.

[0070] Further, in combination with Figure 3 and Figure 4 As shown, the vertical slot 1231 vertically penetrates the end of the roller shaft 123 away from the frame 12, so that the installation operation of the roller 124 is more simple and labor-saving. Of course, the vertical slot 1231 can not penetrate the end of the roller shaft 123 away from the frame 12, and the specific structure can be set according to actual needs.

[0071] In the embodiment, in combination with Figure 3 and Figure 4 As shown, the edge of the end of the roller shaft 123 away from the frame 12 is provided with a chamfer structure 1232. Specifically, during the installation of the roller 124, the roller 124 can be sleeved on the roller shaft 123 along the inclined surface of the chamfer structure 1232, so that the roller 124 is more easily installed on the roller shaft 123.

[0072] In the embodiment, in combination with Figure 3 and Figure 4 As shown, the end of the roller shaft 123 away from the frame 12 is provided with a limiting protrusion 1233. The limiting protrusion 1233 prevents the roller 124 from falling off the roller shaft 123, and fixes the roller 124 on the roller shaft 123 through the limiting protrusion 1233 and the outer wall of the frame 12, thereby achieving the axial fixation of the roller 124.

[0073] Further, as shown in Figure 3 and Figure 4 , the limiting protrusion 1233 is annular, the vertical slot 1231 vertically penetrates the limiting protrusion 1233, and the chamfer structure 1232 is arranged at the edge of the end of the limiting protrusion 1233 away from the frame 12.

[0074] In the embodiment, as shown in Figure 2 and Figure 3 , the bottom 11 is a mesh structure. In use, the tableware is directly placed on the mesh structure, so that the washing water and residues on the tableware directly fall through the holes of the mesh structure, avoiding the problems of bacteria breeding and the like caused by the washing water and residues remaining on the surface of the tableware.

[0075] Embodiment Two

[0076] As shown in Figures 5-8 , the difference between this embodiment and the first embodiment is that the mesh structure of the bottom 11 of the knife and fork tray, which can also be referred to as a knife and fork tray bottom mesh structure, as shown in Figure 5 , includes a plurality of draining strips 111 and a plurality of support teeth 112, as shown in Figure 6 , the draining strips 111 are arranged in a crisscross manner and in a wave shape in the vertical direction, the support teeth 112 are connected to the upward protruding parts of the draining strips 111 and are arranged at intervals and used for supporting the tableware. It should be noted that, as shown in Figure 5 , the support teeth 112 are arranged vertically, and the tableware such as knives, forks and spoons is directly placed on the draining strips 111 and located between two adjacent support teeth 112, thereby playing a role in fixing the tableware. Of course, in other embodiments, the support teeth 112 can be arranged obliquely, so that the tableware is inclined at a certain angle, avoiding the washing water and residues on the tableware remaining on the tableware and causing the tableware to be contaminated.

[0077] The knife and fork tray bottom mesh structure of the embodiment provides more support points for the tableware when the tableware is placed on the draining strips 111 and clamped between two adjacent support teeth 112, because the draining strips 111 are in a wave shape in the vertical direction and the support teeth 112 are connected to the upward protruding parts of the draining strips 111. In this way, when the tableware is clamped into the recessed parts of the draining strips 111, the draining strips 111 and the support teeth 112 provide more support points for the tableware, and the recessed parts can also better accommodate tableware of various shapes and sizes, improving the stability and reliability of the support of the tableware.

[0078] In the embodiment, as shown in Figure 7 and Figure 9 , the bottom 11 is a mesh structure. In use, the tableware is directly placed on the mesh structure, so that the washing water and residues on the tableware directly fall through the holes of the mesh structure, avoiding the problems of bacteria breeding and the like caused by the washing water and residues remaining on the surface of the tableware.As shown in the drawings, the cross section of the draining strip 111 of the knife and fork tray bottom net structure is oval-shaped. The washing water and residues on the tableware can gather and fall along the outer wall of the draining strip 111 under the action of its own gravity, avoiding the pollution caused by the washing water and residues staying on the surface of the tableware, and improving the washing and drying effects of the tableware.

[0079] Further, the long axis of the oval is vertically arranged. In this way, the washing water on the tableware can more quickly gather and fall along the outer wall of the draining strip 111, and the structure has small resistance to the water flow sprayed upward by the knife and fork tray 1, which is beneficial to improve the washing and drying effects of the tableware.

[0080] In the embodiment, as shown in the drawings, Figure 8 and Figure 10 the cross section of the draining strip 111 of the knife and fork tray bottom net structure is quadrilateral-shaped, and the upper side of the quadrilateral is arranged obliquely downward. In this way, the upper surface of the draining strip 111 is obliquely downward, and the washing water and residues on the tableware can quickly gather and flow to the lower part of the knife and fork tray 1 along the upper surface of the draining strip 111, improving the drying effect and avoiding the secondary pollution of the tableware.

[0081] In the embodiment, as shown in the drawings, Figure 8 and Figure 10 the cross section of the draining strip 111 of the knife and fork tray bottom net structure is diamond-shaped. In this way, the structure of the draining strip 111 is regular and convenient to manufacture. Further, the diagonal of the diamond is vertically arranged or horizontally arranged. In this way, the washing water on the tableware can more quickly gather and fall along the outer wall of the draining strip 111, and the structure has small resistance to the water flow sprayed upward by the knife and fork tray 1, which is beneficial to improve the washing and drying effects of the tableware.

[0082] In the embodiment, as shown in the drawings, Figure 6 the supporting teeth 112 of the knife and fork tray bottom net structure are installed at the highest part of the upward protruding part of the draining strip 111. In this way, when the tableware is placed between the supporting teeth 112, the tableware will fall into the downward recessed part of the draining strip 111 under the action of its own gravity, and the discharge of the tableware is more simple, convenient and fast, and the stability and reliability of the support of the tableware are better.

[0083] In the embodiment, as shown in the drawings, Figure 6As shown, the drip strip 111 of the knife and fork tray bottom net structure includes a plurality of sequentially connected drip units 1111, and the drip unit 1111 includes a first straight line segment 11111 and a second straight line segment 11112 sequentially connected, and the first straight line segment 11111 and the second straight line segment 11112 are arranged in a V shape; in this way, after a plurality of drip units 1111 are connected, the entire drip strip 111 is in a wave shape up and down, specifically, when the opening of the V-shaped drip unit 1111 is arranged upward, the first straight line segment 11111 of the previous drip unit 1111 is connected with the second straight line segment 11112 of the next drip unit 1111, and the support column is installed at the connection of the adjacent two drip units 1111, that is, the support tooth 112 is located above the drip unit 1111, when the tableware is placed between the two support teeth 112, the tableware will automatically fall between the first straight line segment 11111 and the second straight line segment 11112 of the drip unit 1111, and since the first straight line segment 11111 and the second straight line segment 11112 are both arranged obliquely, the first straight line segment 11111 and the second straight line segment 11112 can support and fix tableware of any shape and any size, the support of the tableware is stable and reliable, and the placing operation is simple and reliable; in addition, the washing water and residues on the tableware will also flow downward and gather and fall along with the first straight line segment 11111 and the second straight line segment 11112, avoiding the hanging of water on the surface of the tableware to cause the breeding of bacteria on the surface of the tableware and the mildewing of wooden tableware, and improving the washing and drying effect of the tableware.

[0084] In the present embodiment, the included angle between the first straight line segment 11111 and the second straight line segment 11112 of the knife and fork tray bottom net structure ranges from 5° to 60°. Specifically, the included angle between the first straight line segment 11111 and the second straight line segment 11112 can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55° or 60°, and the included angle between the first straight line segment 11111 and the second straight line segment 11112 is arranged in the above range, the inclination angle of the first straight line segment 11111 and the second straight line segment 11112 is reasonable, which is conducive to the gathering and falling of the washing water, if the angle is too small, the first straight line segment 11111 and the second straight line segment 11112 are close to vertical arrangement, so that the space occupied by the drip strip 111 in height is large, which will reduce the loading space of the bowl basket 3 below, in addition, the distance between the upper end of the first straight line segment 11111 and the upper end of the second straight line segment 11112 is close, the spacing between the two support teeth 112 is small, and it is also not convenient for the placement of tableware; if the angle is too large, the first straight line segment 11111 and the second straight line segment 11112 are close to horizontal arrangement, and the washing water and residues on the tableware are not easy to gather and fall downward, which is not conducive to the washing and drying of the tableware.

[0085] In the embodiment, the included angle between the first straight segment 11111 and the second straight segment 11112 ranges from 10° to 30°, the included angle is in the range, the draining effect of the tableware is good, and the tableware is beneficial to cleaning and drying.

Specifically, referring to FIG. 5, the knife, fork and spoon and other tableware are supported by the support teeth 112 in two adjacent support areas 114, and the support teeth 112 in two or three tooth rows 113 in each support area 114 support the tableware, and the support of the tableware is more stable, and the interval between the adjacent two support areas 114 is greater than the interval between the two adjacent tooth rows 113, so that when the tableware is taken out from the knife and fork tray 1, the user can take out the tableware from the gap between the two support areas 114, the gap between the two support areas 114 is large, and the tableware is also more easily taken out. At the same time, the user can also take out the tableware placed in the same support area 114 from the gap between the support areas 114, which is convenient and fast. Figure 5

[0087] In the embodiment, the part of the knife and fork tray bottom net structure between the adjacent two support areas 114 is concave downward to form a groove 115, and the groove 115 extends in the longitudinal direction. Specifically, when the tableware is taken out from the knife and fork tray 1, the user's hand directly enters the groove 115 to take out the tableware, and the tableware is more easily taken out.

[0088] In the embodiment, the depth of the groove 115 of the knife and fork tray bottom net structure is greater than or equal to the thickness of the user's finger. Specifically, when the tableware is taken out from the knife and fork tray 1, the user's hand can be completely bent into the groove 115 to take out the tableware, and the tableware is more easily taken out.

[0089] In the embodiment, referring to FIGS. 5 and 6, the support teeth 112 of the knife and fork tray bottom net structure form tooth rows 113 in the longitudinal direction, and the tooth rows 113 are arranged at intervals in the transverse direction; two or three adjacent tooth rows 113 form a support area 114, and the interval between adjacent two support areas 114 is greater than the interval between the two adjacent tooth rows 113. In use, the tableware is placed transversely between the support teeth 112, so that the tableware spans several support areas 114, and the tableware is supported by the support teeth 112 in the plurality of tooth rows 113, and the support of the tableware is more stable and reliable. Specifically, referring to FIG. 5, the knife, fork and spoon and other tableware are supported by the support teeth 112 in two adjacent support areas 114, and the support teeth 112 in two or three tooth rows 113 in each support area 114 support the tableware, and the support of the tableware is more stable, and the interval between the adjacent two support areas 114 is greater than the interval between the two adjacent tooth rows 113, so that when the tableware is taken out from the knife and fork tray 1, the user can take out the tableware from the gap between the two support areas 114, the gap between the two support areas 114 is large, and the tableware is also more easily taken out. At the same time, the user can also take out the tableware placed in the same support area 114 from the gap between the support areas 114, which is convenient and fast. Figure 9 Figure 10 ​​As shown, the supporting tooth 112 of the knife and fork tray bottom net structure comprises a conical column part 1121 and a plurality of reinforcing ribs 1122, the lower end of the conical column part 1121 is connected with the draining strip 111, the reinforcing ribs 1122 are arranged on the outer peripheral wall of the conical column part 1121 and are arranged in a circumferential direction of the conical column part 1121 in a spaced manner and are parallel to the axis direction of the conical column part 1121; in the direction from top to bottom, the cross-sectional size of the reinforcing ribs 1122 becomes smaller and smaller, and the cross-sectional size of the conical column part 1121 becomes smaller and smaller. Specifically, the reinforcing ribs 1122 are arranged on the outer peripheral wall of the conical column part 1121, which can increase the structural strength of the supporting tooth 112 and ensure that the tableware is stably and reliably supported; in addition, in the direction from top to bottom, the cross-sectional size of the reinforcing ribs 1122 becomes smaller and smaller, and the cross-sectional size of the conical column part 1121 becomes smaller and smaller, so that the washing water on the tableware can quickly fall along the outer peripheral wall of the conical column part 1121 and the surface of the reinforcing ribs 1122, which is conducive to the drying of the tableware.

[0090] Further, the number of reinforcing ribs 1122 can be one, two, three, four or more, the reinforcing ribs 1122 are arranged in a circumferential direction of the conical column part 1121 in a uniformly spaced manner, the more the number of reinforcing ribs, the better the structural strength of the supporting tooth 112, and the more stable and reliable the support of the tableware.

[0091] In this embodiment, referring to Figure 9 and Figure 10 As shown, the upper end surface of the conical column part 1121 of the knife and fork tray bottom net structure is an upwardly convex arc surface 1123. The arrangement of the arc surface 1123 makes the upper end surface of the conical column part 1121 not easy to accumulate residues and store water, which is conducive to avoiding secondary pollution of the tableware, in addition, the arc surface 1123 has a good touch feeling and a good use feeling for the user, and will not scratch the user.

[0092] The remaining parts of this embodiment are the same as those of Embodiment One, and the features not explained in this embodiment all adopt the explanations of Embodiment One, which will not be described here in detail.

[0093] Embodiment Three

[0094] The knife and fork tray 1 provided in this embodiment comprises a surrounding frame 12 and the above-described knife and fork tray bottom net structure, the surrounding frame 12 is arranged around the knife and fork tray bottom net structure and is connected with the draining strip 111. The specific structure of the knife and fork tray 1 is referred to Embodiment Two, since the knife and fork tray 1 adopts all the technical solutions of the above-described knife and fork tray bottom net structure, it also has all the beneficial effects brought by the technical solutions of the above-described embodiments, which will not be described here in detail.

[0095] The remaining parts of this embodiment are the same as those of Embodiment One, and the features not explained in this embodiment all adopt the explanations of Embodiment One, which will not be described here in detail.

[0096] Example 4

[0097] like Figures 10-14 As shown, the difference between this embodiment and Embodiment Two is that the cutlery tray 1 includes a body 10, the body 10 has a mounting cavity 20 for accommodating cutlery, and the bottom surface of the mounting cavity 20 is provided with multiple support teeth 112. It should be noted that, referring to... Figure 10 As shown, the main body 10 includes a bottom 11 and a frame 12. The frame 12 surrounds the bottom 11 and together with the bottom 11 forms an installation cavity 20 for accommodating tableware. The bottom 11 can be the cutlery tray bottom mesh structure of the above embodiment 2. The bottom 11 can also be formed by multiple straight drain strips 11 connected in a crisscross pattern, or it can be other structures. The specific structure can be selected according to actual needs.

[0098] Furthermore, combined Figure 11 As shown, the support teeth 112 are located within the mounting cavity 20 and are used to support the tableware. The support teeth 112 are arranged in a dot matrix pattern, and the heights of any two adjacent support teeth 112 are different. It should be noted that, combined with... Figure 13 As shown, in the lateral direction, the heights of two adjacent support teeth 112 are not the same; combined with Figure 14 As shown, in the longitudinal direction, the heights of two adjacent support teeth 112 are also different.

[0099] The cutlery tray 1 of this embodiment features a dot-matrix arrangement of support teeth 112, allowing cutlery to be placed horizontally, vertically, or at an angle, thus enabling placement at any angle. Furthermore, the inconsistent heights of adjacent support teeth 112 indicate a greater distance between their upper ends, making it easier for cutlery to fall between them and thus providing support. In practical application, multiple cutlery pieces can be randomly tossed into the cutlery tray 1; under their own weight, they will automatically disperse and fall between adjacent support teeth 112, achieving stable support. This allows for simple, convenient, and efficient loading of cutlery into the tray 1, enhancing the user experience.

[0100] In this embodiment, the support teeth 112 are evenly and dispersed, and compared with the existing cutlery tray 1 with a dense support structure, the spacing between the cutlery is larger, which can provide better washing and drying effects.

[0101] In this embodiment, combined with Figure 11As shown, when the support teeth 112 are divided into a plurality of support areas 114, the support teeth 112 in each support area 114 are arranged in a lattice, and the bottom surface of the installation cavity 20 is recessed downward to form a groove 115 between two adjacent support areas 114, the groove 115 extending in the longitudinal direction; the groove 115 is divided into a shallow groove 1151 and a deep groove 1152, the depth of the shallow groove 1151 being less than that of the deep groove 1152; specifically, as shown in Figure 11 , Figure 13 and Figure 14 As shown, the support areas 114 are divided into four, the groove 115 between two support areas 114 on the same side is a shallow groove 1151, the groove 115 between the two middle support areas 114 is a deep groove 1152, the depth of the shallow groove 1151 being less than that of the deep groove 1152, the shallow groove 1151 being used for placing small-sized tableware, such as knives, forks, etc.; the deep groove 1152 being used for placing large-sized tableware, such as soup spoons, spatulas, etc. The arrangement of the shallow and deep grooves 1151 can meet the arrangement requirements of large-sized tableware on one hand, and on the other hand, the loading height space of the knife and fork tray 1 and the bowl basket 3 located below it is maximized, improving the loading capacity of the dishwasher; in addition, the deep groove 1152 is also conducive to supporting large-sized spoon-shaped tableware, the large-sized part of the spoon-shaped tableware being placed in the deep groove 1152, and the pie part being clamped in the tooth row 113, meeting the loading requirements of diversified tableware.

[0102] In the present embodiment, as shown in Figure 12 Any two adjacent support teeth 112 are divided into a first support tooth 1124 and a second support tooth 1125, the height of the first support tooth 1124 being greater than that of the second support tooth 1125. The first support tooth 1124 and the second support tooth 1125 are arranged in an interlaced and spaced manner, thereby forming a support structure, so that the support teeth 112 have only two heights, and the support teeth 112 of the two heights are arranged in an interlaced and spaced manner, so that the overall shape of the support structure is regular, facilitating manufacturing.

[0103] In this embodiment, the height of the first support tooth 1124 is H1, and the height of the second support tooth 1125 is H2. H1 and H2 satisfy the following relationship: H1 / 3≤H2≤H1 / 2. Specifically, the height H2 of the second support tooth 1125 is set within the above range when H2 = H1 / 3, H2 = 0.34H1, H2 = 0.35H1, H2 = 0.36H1, H2 = 0.37H1, H2 = 0.38H1, H2 = 0.39H1, H2 = 0.4H1, H2 = 0.41H1, H2 = 0.42H1, H2 = 0.43H1, H2 = 0.44H1, H2 = 0.45H1, H2 = 0.46H1, H2 = 0.47H1, H2 = 0.48H1, H2 = 0.49H1, or H2 = 0.5H1. This ensures that the first support tooth 112... The height difference between the first support tooth 1124 and the second support tooth 1125 is within a reasonable range, ensuring that the tableware can smoothly enter between the two adjacent support teeth 112, making it easier to place and ensuring that the tableware is stably and reliably supported. If the height difference is set too large, the height of the second support tooth 1125 will be smaller than the height of the first support tooth 1124, and the second support tooth 1125 will not be able to stably support the tableware. If the height difference is set too small, the distance between the upper end of the first support tooth 1124 and the upper end of the second support tooth 1125 will be small, and the tableware will not easily slide between the two adjacent support teeth 112, making it difficult to place the tableware.

[0104] In this embodiment, refer to Figure 13 and Figure 14 As shown, the end face of the frame 12 away from the bottom 11 is inclined downwards. Specifically, the end face of the frame 12 away from the bottom 11 can extend downwards inclined in the direction towards the mounting cavity 20, so that the washing water and residue on the upper part of the frame 12 will automatically fall into the mounting cavity 20 along the inclined direction of its end face, and finally flow out from the bottom 11 of the cutlery tray 1. Alternatively, the end face of the frame 12 away from the bottom 11 can extend downwards inclined in the direction towards the outside of the mounting cavity 20, so that the washing water and residue on the upper part of the frame 12 will flow onto the outer wall of the frame 12 along the inclined direction of its end face, and finally flow out along the outer wall of the frame 12. The downward inclined arrangement of the end face of the frame 12 away from the bottom 11 is advantageous. The top water flow is guided in a way that prevents food residue from accumulating, thus improving the cleaning and drying effect of the tableware. Alternatively, a portion of the end face of the frame 12 away from the bottom 11 extends downwards at an angle toward the mounting cavity 20, while the other portion of the end face of the frame 12 away from the bottom 11 extends downwards at an angle away from the mounting cavity 20. In this way, the washing water and food residue on the upper part of the frame 12 are divided into two parts and fall downwards at an angle to the bottom of the cutlery tray 1, which is conducive to the top water flow and prevents food residue from accumulating, thus improving the cleaning and drying effect of the tableware. Of course, other structures can also be used, as long as they are conducive to the top water flow and prevent food residue from accumulating.

[0105] The rest of this embodiment is the same as that in Embodiment 2. Features not explained in this embodiment are explained using the methods in Embodiment 2, and will not be repeated here.

[0106] Example 5

[0107] like Figures 15-20 As shown, the difference between this embodiment and Embodiment 2 is that: [The following text appears to be a continuation of the previous sentence and can be left as is:] Figure 15 , Figure 16 and Figure 17 As shown, the cutlery tray 1 also includes a handle cover 13. A fixing cavity 116 is provided on the end face of the frame 12 near the bottom 11. The handle cover 13 is fastened in the fixing cavity 116. The side wall of the fixing cavity 116 away from the mounting cavity 20 is the handle wall 1221. The handle cover 13 is set close to the handle wall 1221. The side of the handle cover 13 near the mounting cavity 20 and the inner wall of the fixing cavity 116 together form a recessed groove 14 for the user's fingers to be inserted.

[0108] Specifically, in the knife and fork tray 1 of this application embodiment, after the handle cover 13 is fastened in the fixing cavity 116, when the knife and fork tray 1 is pushed into and pulled into the washing cavity 4 of the dishwasher, the user's hand directly reaches into the clearance groove 14 and grasps the handle cover 13 and the handle wall 1221, thereby pushing and pulling the knife and fork tray 1. The setting of the handle cover 13 increases the thickness of the handle part 122 of the knife and fork tray 1, improves the overall structural strength of the handle part 122, and also improves the pushing and pulling feel of the knife and fork tray 1.

[0109] In this embodiment, the recessed groove 14 is designed to allow the user's hand to reach in and push or pull the handle 122 of the cutlery tray 1 without wasting the loading space of the cutlery tray 1.

[0110] In this embodiment, refer to Figure 15 As shown, the fixing cavity 116 extends along the circumference of the frame 12 to form an annular chamber, which reduces the overall weight of the cutlery tray 1 and achieves a lightweight design. At the same time, the side wall of the annular chamber near the mounting cavity 20 at the handle portion 122 protrudes towards the mounting cavity 20, thereby increasing the space of the clearance groove 14 and making it more comfortable and convenient for the user to reach in. Of course, in other embodiments, in order to ensure the structural strength of the entire cutlery tray 1, the fixing cavity 116 can be opened only in the handle portion 122 of the frame 12, and its specific structure can be selected according to actual needs.

[0111] In this embodiment, refer to Figure 17As shown, the handle cover 13 is provided with a elastic buckle 131, and the inner wall of the emptying groove 14 is provided with a buckle structure 1161 matched with the elastic buckle 131. Specifically, the handle cover 13 is installed by buckling the elastic buckle 131 on the buckle structure 1161, and the installation operation is simple and easy to manufacture.

[0112] Optionally, the number of the elastic buckle 131 can be one, two, three or more, and the more the number of the elastic buckle 131, the better the installation reliability of the handle cover 13.

[0113] In the embodiment, referring to Figure 17 As shown, the elastic buckle 131 includes a first protruding part 1311 arranged at the end of the handle cover 13 close to the bottom surface of the fixing cavity 116, and the buckle structure 1161 includes a second protruding part 11611 arranged on the inner wall of the fixing cavity 116, and the first protruding part 1311 can be hooked on the second protruding part 11611. Specifically, when installing, the handle cover 13 is only needed to be pushed into the fixing cavity 116, so that the first protruding part 1311 is hooked on the second protruding part 11611, and the installation of the handle cover 13 can be realized, and the structure is simple and reliable.

[0114] In the embodiment, the handle cover 13 and the whole knife and fork tray 1 are made of plastic, and it is necessary to note that, referring to Figure 17 As shown, the handle cover 13 has a certain deformation capacity, so that when the first protruding part 1311 is hooked on the second protruding part 11611, the first protruding part 1311 is located above the second protruding part 11611, and when the handle cover 13 is pushed into the fixing cavity 116 from below, the second protruding part 11611 pushes the first protruding part 1311 to deform in the direction away from the second protruding part 11611, so that the first protruding part 1311 is hooked on the second protruding part 11611 after passing the second protruding part 11611, and the buckling of the elastic buckle 131 and the buckle structure 1161 is realized, that is, the fixing of the handle cover 13 is realized.

[0115] In the embodiment, referring to Figure 18 and Figure 19As shown in the figure, the handle wall 1221 is provided with a guide groove 11621 extending along the depth direction of the fixing cavity 116, and the handle cover 13 is provided with a guide structure 132 in sliding connection with the guide groove 11621. Specifically, before the first protruding part 1311 is buckled on the second protruding part 11611, the guide structure 132 on the handle cover 13 is clamped into the guide groove 11621 and slides into the fixing cavity 116 under the guidance of the guide groove 11621 until the first protruding part 1311 is buckled on the second protruding part 11611, so as to realize the buckling of the handle cover 13. At the same time, through the guidance of the guide groove 11621 and the guide structure 132, the first protruding part 1311 can be accurately hooked on the second protruding part 11611, and the installation of the handle cover 13 can be completed through sliding and buckling, which is simple and reliable in structure.
