The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1 to 13, an embodiment of the present invention provides a matching structure of an inner container and a base, which is mainly applied to a dishwasher. The following description of the orientation words of the matching structure of the inner container and the base in the embodiment, for example, the specific examples of the inner container, the outer container, the bottom and the top can be seen with reference to fig. 5 and 12-13.

Specifically, as shown in fig. 1-2 and fig. 6, the matching structure of the inner container and the base includes a base 20 and an inner container 10, a groove 30 is provided at the top of the base 20, the inner container 10 includes a side plate 11, a plurality of plug connectors 40 are provided at the bottom of the side plate 11, the plug connectors 40 are provided in plurality, the plug connectors 40 are arranged at intervals along the length direction of the bottom of the side plate 11, and each plug connector 40 is inserted into the groove 30 so that the inner container 10 is assembled with the base 20. The inner container 10 may be made of a metal material, and the base 20 may be made of a plastic material.

Preferably, as shown in fig. 6, the groove 30 is disposed near the periphery of the top of the base 20, so that the washing cavity defined between the top of the base 20 and the inner container 10 can be maximized.

According to the matching structure of the inner container and the base, provided by the embodiment of the invention, the bottom of the side plate 11 of the inner container 10 is provided with the plurality of plug connectors 40, and the plug connectors 40 are arranged at intervals along the length direction of the bottom of the side plate 11, when the side plate 11 is inserted into the groove 30 arranged on the base 20, the plug connectors 40 are also inserted into the groove 30 at the same time, because a space interval is formed between every two adjacent plug connectors 40, the space interval can avoid being in contact with the groove wall of the groove 30, so that the contact area between the side plate 11 and the groove wall of the groove 30 is reduced, namely the contact area between the whole inner container 10 and the base 20 is reduced, the difficulty of inserting the side plate 11 of the inner container 10 into the groove 30 of the base 20 is reduced, the assembly difficulty between the inner container 10 and the base 20 is reduced, and thus, the assembly between the inner container 10 and the base 20 is easier to realize, the assembly efficiency between the liner 10 and the base 20 is improved, the assembly production cost between the liner 10 and the base 20 is reduced, and the production benefit of enterprises is greatly improved.

Furthermore, as shown in fig. 1 to 2, in the plurality of plug-in components 40 of the present embodiment, every two adjacent plug-in components 40 are disposed at equal intervals, so that the stress when each part of the side plate 11 abuts against the groove 30 in the length direction is ensured to be more balanced, and the stability after the assembly between the inner container 10 and the base 20 can be ensured to be better.

Furthermore, the matching structures of the liner and the base of the present embodiment are respectively arranged at the left side, the right side and the rear side of the assembled connection of the liner 10 and the base 20.

In this embodiment, as shown in fig. 5 to 6 and 8, the base 20 is provided with a positioning boss 50 and a guiding boss 60 protruding toward the top of the inner container 10 at an interval, the groove 30 is formed between the positioning boss 50 and the guiding boss 60, and the groove 30 includes a bottom mounting surface 21 formed on the top of the base 20, a first side mounting surface 51 formed on the positioning boss 50, and a second side mounting surface 61 formed on the guiding boss 60; the side plate 11 abuts against the first side mounting surface 51, and each of the plug-in units 40 abuts against the bottom mounting surface 21 and the second side mounting surface 61. Specifically, when the plug-in connector 40 provided at the bottom of the side plate 11 of the inner container 10 is inserted into the groove 30, the bottom of the side plate 11 and the plug-in connector 40 are restricted by the positioning boss 50 and the guide boss 60 which together form the groove 30. That is, the first side mounting surface 51 limits the lateral plate 11 to move and displace in the peripheral horizontal direction, the second side mounting surface 61 limits the plug connectors 40 to move and displace in the peripheral horizontal direction, the bottom mounting surface 21 limits the plug connectors 40 and the lateral plate 11 to move and displace vertically and downwardly, and the friction force generated between the first side mounting surface 51 and the second side mounting surface 61 and between the lateral plate 11 and the plug connectors 40 can limit the plug connectors 40 and the lateral plate 11 to move and displace vertically and upwardly, so that the position stability of the assembled liner 10 can be effectively ensured.

Preferably, the positioning bosses 50 and the guiding bosses 60 are integrally injection-molded with the base 20, and the integrally injection-molded design can enable various structures on the whole base 20 to be more integrated, so that the product consistency is better.

More preferably, as shown in fig. 5, the positioning boss 50 has a height lower than that of the guide boss 60. Thus, the partial structure of the guide boss 60 higher than the positioning boss 50 is used for guiding the insertion of the side plate 11 of the inner container 10 and the plug connector 40, further facilitating the assembly of the inner container 10 and the base 20 and improving the assembly efficiency of the dishwasher.

Preferably, the distance between every two adjacent plug-in connectors 40 in the present embodiment is in the range of 80mm to 130 mm. Specifically, the pitch between two plug-in units 40 may be 80mm, 90mm, 100mm, 110mm, 120mm, or 130 mm. The total amount of plug connectors 40 can be 6 ~ 12, and plug connectors 40 on every curb plate 11 can be 2 ~ 4, and actual quantity can be optimized according to the inner bag 10 of different models and set for.

In the prior art, in order to ensure that the inner container 10 is more easily assembled with the base 20, it is a common practice to set the width of the groove 30 on the base 20 to be larger, and generally the width of the groove 30 is set to be thicker than the inner side of the inner container 10 by more than 4mm, so that the inner container 10 can be ensured to be more easily assembled with the base 20, but this causes the side plate 11 to be further away from the edge of the base 20, and the washing cavity formed by the enclosure between the inner container 10 and the base 20 is reduced.

However, in the present embodiment, the width of the groove 30 is 1mm to 3mm thicker than the width of the side plate 11, and specifically, the width of the groove 30 is 1mm, 2mm, or 3mm thicker than the width of the side plate 11. That is, the width of the groove 30 may be set to be at least 1mm thicker than the thickness of the side plate 11. The narrower the width of the groove 30, the positioning projection 50 and the guiding projection 60 forming the groove 30 can be set to a position closer to the edge of the top of the base 20, so that the washing cavity enclosed between the liner 10 and the base 20 can be larger in a limited volume.

In this embodiment, even if the width of the groove 30 is set to be 1mm thicker than the thickness of the side plate 11, the plurality of plug-in units 40 arranged at intervals can still facilitate the plug-in units 40 to be plugged into the groove 30.

In this embodiment, as shown in fig. 3 and 5, each of the plug-in connectors 40 includes a transverse plate 41 and a vertical plate 42, the transverse plate 41 is bent from the bottom of the side plate 11 along the transverse direction, and the vertical plate 42 is bent from the end of the transverse plate 41 along the vertical direction; each of the lateral plates 41 abuts against the bottom mounting surface 21, and each of the vertical plates 42 abuts against the second side mounting surface 61. Specifically, the plug-in unit 40 is substantially L-shaped, and forms a U-shaped trimming structure together with the side plate 11, so that the bottom of the side plate 11 can be placed too sharply, and the phenomenon that the bottom of the side plate 11 scratches hands of the inner container 10 in the moving or assembling process is prevented. More importantly, it is possible to make the plug-in unit 40 have a certain elasticity, and the existence of the elasticity makes the plug-in unit 40 naturally generate the force abutting against the base 20, the positioning boss 50 and the guide boss 60. Therefore, a larger friction force can be generated between the side plate 11 and the positioning boss 50, a larger friction force can be generated between the transverse plate 41 and the top of the base 20, a larger friction force can be generated between the vertical plate 42 and the guide boss 60, and the stability and reliability of the assembly between the plug-in unit 40 and the groove 30 can be effectively enhanced by the increased friction force.

Further, as shown in fig. 3 and 5, the transverse plate 41 is smooth and arc-shaped, so that the overall aesthetic property of the liner 10 can be improved, the stress concentration phenomenon on the liner 10 can be relieved, the forming quality of the liner 10 is improved, and the service life of the liner 10 is ensured or even prolonged.

In this embodiment, the guide boss 60 is of unitary construction (see fig. 6 and 8) and the positioning boss 50 is of unitary construction (not shown). Specifically, the guide bosses 60 are designed to be integral to correct the plug-in unit 40 when the plug-in unit 40 is inserted into the groove 30, i.e., correct and maintain the positions of the plug-in units 40 consistent through the guide bosses 60 of the integral structure. Similarly, the positioning boss 50 of the integral structure can correct the position of the bottom of the side plate 11, so that the position of the bottom of the side plate 11 is kept consistent. Meanwhile, the positioning boss 50 of the integral structure can enhance the sealing performance of the abutting joint with the side plate 11, so that the washing water is prevented from entering the groove 30, and the water stored in the groove 30 is prevented from corroding the bottoms of the plug-in connector 40 and the side plate 11.

In addition, in this embodiment, the positioning boss 50 may also be an intermittent structure (see fig. 6 and 8), and the setting of the positioning boss 50 with the intermittent structure can reduce the contact area of the inner container 10, thereby further reducing the difficulty in assembling the inner container 10 and the base 20.

Preferably, the positioning bosses 50 of the discontinuous structure correspond to the plug connectors 40 arranged at intervals one by one, so that the contact area between the base 20 and the liner 10 can be reduced, and meanwhile, the effective contact between the base 20 and the liner 10 is maintained to easily generate enough friction force to improve the stability of the assembly of the base 20 and the liner 10.

In the present embodiment, each of the plug members 40 is integrally press-molded with the side plate 11. The plug-in unit 40 and the side plate 11 are integrally press-molded by a metal material, and preferably, the entire inner container 10 is also integrally press-molded by a metal material. The integrated punch forming is beneficial to ensuring the consistency of the inner container 10 products, and can reduce production processes, such as welding processes, and further reduce production cost.

In this embodiment, the structures of the guide bosses 60 on the left side, the right side, and the rear side of the inner container 10 assembled with the base 20 may be the same or different. Preferably, the guide bosses 60 at the left and right sides where the inner container 10 is assembled with the base 20 have the same structure.

In this embodiment, as shown in fig. 6 and 12 to 13, the guiding structure located at the rear side of the inner container 10 assembled and connected with the base 20 preferably includes a limiting plate 70 and a guiding plate 80, the top end of the limiting plate 70 is connected with the top of the base 20 and is arranged along the vertical direction, the guiding plate 80 includes a supporting portion 81 and a guiding portion 82, the supporting portion 81 is connected to the outer side of the limiting plate 70, a step 90 is formed between the inner side surface of the supporting portion 81 and the top end surface of the limiting plate 70, the guiding portion 82 extends upward from the top end surface of the supporting portion 81, and a guiding arc surface 83 arranged from the top end surface of the guiding portion 82 to the bottom end surface of the guiding portion 82 is formed on the inner side surface of the guiding portion 82.

Specifically, the guide plate 80 of the guide boss 60 serves to guide the attachment of the connector 40 to be attached to the base 20, and the position restricting plate 70 of the guide boss 60 serves to restrict the position of the connector 40 which has been inserted into the recess 30. Wherein, the inner side of the guide part 82 of the guide plate 80 is formed with a guide arc surface 83 arranged from the top end surface of the guide part 82 to the bottom end surface of the guide part 82, so the plug-in unit 40 can be well guided and limited at the inner side of the limit plate 70 by the guide arc surface 83, and the step 90 is formed between the inner side of the support part 81 of the guide plate 80 and the inner side of the limit plate 70, the guide plate 80 can be effectively prevented from distortion deformation during injection molding by the step 90, so the thickness of the guide plate 80 can be designed to be proper, thereby not only preventing the possibility of shrinkage due to the too thick guide plate 80, but also preventing the distortion deformation due to the too thin guide plate 80. Since the groove 30 is deformed once the guide projection 60 is distorted, the insertion of the plug-in unit 40 into the groove 30 may not be well matched with the groove 30 due to the deformation of the groove 30, and the assembly between the inner container 10 and the base 20 may be difficult. Such structural design in this embodiment can effectively avoid whole direction boss 60 distortion to appear when moulding plastics, and structural design practicality is strong.

Further, the arc center of the guiding arc 83 (i.e., the center of the circle to which the guiding arc 83 belongs) is located outside the stopper plate 70 and outside the guide plate 80. This ensures that the guide arc 83 is formed to be convex in the inward direction, and thus functions to guide the installation of the plug 40 by being tangent to the plug 40 when the guide liner 10 is installed.

Here, in order to better display the bottom end surface of the guide portion 82 and the top end surface of the support portion 81, as shown in fig. 13, the bottom end surface of the guide portion 82 and the top end surface of the support portion 81 are shown by a dotted line indicated in a lateral direction, that is, the guide portion 82 and the support portion 81 are connected to each other such that the bottom end surface of the guide portion 82 and the top end surface of the support portion 81 overlap.

Preferably, the guide portion 82 and the support portion 81 are integrally molded.

In addition, in the prior art, in order to ensure that the guide pieces mounted on the guide liner 10 are prevented from deforming, the guide pieces are designed to be thicker, and although the thicker guide pieces can prevent deformation to a certain extent, shrinkage occurs during injection molding production, so that a person skilled in the art can design the maximum thickness of the guide structure to be about 5mm in consideration of the problems of avoiding shrinkage and easy deformation of the guide pieces. In practice, however, if it is necessary to design the guide structure even further thinner, there is only a very limited thickness margin that can be reduced. However, the guide boss 60 designed in the present embodiment can be designed to be about 4mm, even less than 4mm, at the thickest part by the above-mentioned structural limitation, and in the case of further reducing the thickness of the thickest part of the guide boss 60, it can also be ensured that the guide boss 60 does not have injection molding distortion.

More specifically, as shown in fig. 13, the step 90 of the present embodiment is designed such that a step difference is formed between the supporting portion 81 of the guide plate 80 and the position-limiting plate 70, and thus the joint between the guide plate 80 and the position-limiting plate 70 is formed at the position of the step 90, so that even if an external force acts on the guide plate 80, if the guide plate 80 tends to twist, the guide plate 80 will not twist under the limitation of the step 90, and thus the occurrence of injection molding twisting deformation can be effectively prevented.

Further, as shown in fig. 13, the supporting portion 81 of the guide plate 80 in the embodiment is connected to the outer side of the stopper plate 70, that is, the supporting portion 81 of the guide plate 80 is not directly connected to the outer side of the stopper plate 70, and specifically, a connecting plate 100 having a certain thickness is connected between a portion of the inner side surface of the supporting portion 81 of the guide plate 80 close to the bottom end surface of the supporting portion 81 and a portion of the outer side surface of the stopper plate 70 close to the top end surface of the stopper plate 70, that is, the connecting plate 100 is connected between the supporting portion 81 and the stopper plate 70, and the connecting plate 100 may be integrally formed with the stopper plate 70, or the connecting plate 100 may be integrally formed. Preferably, the stopper plate 70, the connecting plate 100 and the guide plate 80 are integrally formed. This connecting plate 100 set up can reduce the possibility of limiting plate 70 and the junction deformation of the supporting part 81 of deflector 80, strengthens the intensity of the junction of limiting plate 70 and the supporting part 81 of deflector 80, and then can effectively prevent this distortion to take place when the supporting part 81 of deflector 80 receives the power of ordering about deflector 80 distortion, avoids the direction boss 60 distortion to appear and leads to the product bad.

Here, in order to better show the connection plate 100, as shown in fig. 13, a connection point of the connection plate 100 and the inner side surface of the support portion 81 is shown by a vertical dotted line, that is, the connection plate 100 and the support portion 81 are connected to each other such that the outer side surface of the connection plate 100 and the inner side surface of the support portion 81 overlap.

In this embodiment, the guiding boss 60 further includes a plurality of guiding ribs 85, each guiding rib 85 is disposed on the step 90 and arranged at intervals along the length direction of the step 90, the bottom end surface of each guiding rib 85 is connected with the top end surface of the limiting plate 70, and the outer side surface of each guiding rib 85 is connected with the inner side surface of the supporting portion 81. The number of the guiding ribs 85 may be set more practically, for example, five, six, or less than five or more than six. Specifically, the arrangement of the guide ribs 85 can strengthen the connection strength between the limiting plate 70 and the guide plate 80, so that the connection stability between the limiting plate 70 and the guide plate 80 is improved; and the guiding cambered surface 83 formed on the inner side surface of the guiding part 82 of the guiding plate 80 can be connected, so that when the inner container 10 of the dishwasher is guided to be installed on the base 20 of the dishwasher, the inner container can be guided by the guiding cambered surface 83 firstly, then the inner side surface of the guiding rib 85 continues to guide, and finally, the part where the inner container 10 of the dishwasher is connected with the base 20 can be guided to the inner side of the limiting plate 70.

More importantly, as shown in fig. 7 and fig. 12 to 13, the guiding rib 85 is disposed on the step 90, and the guiding rib 85 is fixedly connected to the supporting portion 81 and the limiting plate 70, so that once an external force causes the guiding plate 80 to be distorted, the guiding rib 85 and the step 90 cooperate to prevent the distortion tendency from occurring, thereby more effectively preventing the guiding plate 80 from being injection-molded and distorted, and further preventing the guiding boss 60 from being injection-molded and distorted.

Moreover, as shown in fig. 7, the guiding ribs 85 are spaced at intervals, so as to effectively prevent distortion, and the whole thickness of the guiding boss 60 is not thickened, that is, shrinkage during injection molding does not occur.

Further, the respective guide ribs 85 are arranged in parallel with each other. Meanwhile, the respective guide ribs 85 are provided at equal intervals. The design can make the supporting force of each guide rib 85 on the guide part 82 and the limiting plate 70 more uniform and effective. But also the guiding action to the inner container 10 is more effective.

In this embodiment, an included angle C formed between the inner side surface of each of the guide ribs 85 and the top end surface of the stopper plate 70 is 60 ° to 80 °. Structural design like this can ensure that the medial surface of direction muscle 85 forms fine linking with direction cambered surface 83, cooperates like this to lead cambered surface 83 and install the inner bag 10 guide that needs to install on base 20 jointly.
