DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] The embodiment discloses a fixing structure of a dishwasher inner container and a base, referring to Figures 1-7 , comprising an inner container 1 and a base 2. The bottom of the inner container 1 is open, and a lower edge 11 is formed at the bottom of the inner container 1. The base 2 is installed at the open part of the bottom of the inner container 1, and an upper edge 21 is formed at the upper part of the inner container 1, and they are sleeved with each other.

[0029] Referring to Figure 1 , Figure 2 , Figure 3 , the bottom of the inner container 1 is open, and the front side is pressed open, so that three lower edges 11 are formed at the lower part of the inner container 1, which are respectively located at the left side, the right side and the rear side of the inner container 1. Three upper edges 21 are formed at the upper side of the base 2, which are respectively located at the left side, the right side and the rear side of the base 2. The upper edges 21 correspond to the lower edges 11 one by one, and can be clamped and fixed at the connection part. The lower edges 11 of the inner container 1 and the upper edges 21 of the base 2 can be clamped and limited to each other, and are fixed by screw locking.

[0030] Referring to Figure 4 、 Figure 5 As shown in FIG. 1, a stepped surface 211 is integrally formed in the inner periphery of the upper edge 21 of the base 2, and the stepped surface 211 is upwardly arranged. A lower bottom surface 111 is formed on the lower side of the lower edge 11 of the inner container 1, and the size and position of the lower bottom surface 111 are matched with the stepped surface 211, and the lower bottom surface 111 is pressed against the stepped surface 211, so that the upper and lower limiting can be achieved.

[0031] Moreover, since the upper edge 21 of the inner container 1 is sleeved on the inner periphery of the lower edge 11 of the base 2, after being sleeved, the horizontal direction clamping limiting can be achieved, and the assembly stability of the inner container 1 and the base 2 can be maintained.

[0032] In order to improve the connection sealing between the inner container 1 and the base 2, a fillet portion 212 is integrally formed on the upper side of the stepped surface 211, and a fillet groove portion 112 is formed on the lower bottom surface 111, and the fillet portion 212 is embedded in the fillet groove portion 112. After the fillet portion 212 and the fillet groove portion 112 are matched with each other, a zigzag connection surface can be formed, which not only can improve the assembly stability, but also can play a sealing and flow limiting role.

[0033] The bottoms of the three lower edges 11 of the inner container 1 are connected with each other, that is, the three lower bottom surfaces 111 are connected with each other and kept flush, and the three fillet groove portions 112 of the three lower bottom surfaces 111 are also connected with each other to form a structure for semi-surrounding the inner cavity of the inner container; the stepped surfaces 211 of the inner peripheries of the three upper edges 21 are also kept in a flush state, and the three fillet portions 212 are also integrally connected with each other to form a semi-surrounding structure, which is matched with the three fillet groove portions 112.

[0034] After the lower edge 11 of the inner container 1 and the upper edge 21 of the base 2 are clamped and fixed with each other, the auxiliary limiting role is played through the clamping structure.

[0035] Referring to Figure 6 、 Figure 7 As shown in FIG. 1, an upper clamping portion 12 is arranged on the lower edge 11 of the inner container 1, and a lower clamping portion 22 is arranged on the upper edge 21 of the base 2, the lower clamping portion 22 and the upper clamping portion 12 correspond to each other and are clamped with each other. Specifically, the upper clamping portion 12 is a clamping block fixedly connected to the outer periphery of the lower edge 11, and the lower clamping portion 22 is a clamping groove formed on the lower edge 11, and when installed, the clamping block is clamped into the clamping groove.

[0036] The lower side of the clamping block is formed with an inclined guide surface 121, and the upper side of the clamping block is formed with a limiting surface 122, which is substantially horizontally structured. During the clamping of the clamping block into the clamping groove, the guide surface 121 of the lower side of the clamping block is first abutted against the upper edge 21 of the base 2, and during the insertion of the lower edge 11, the guide surface 121 can form an inclined guide to enable the lower edge 11 of the inner container 1 to be elastically deformed towards the inner circumferential direction of the inner container 1, so that the upper clamping portion 12 can be clamped and fixed in the lower clamping portion 22. After clamping, the limiting surface 122 of the upper side of the clamping block can abut against the inner side upper portion of the clamping groove in the clamping groove, and the limiting in the upward pulling direction is achieved, thereby achieving the limiting and fixing of the inner container 1.

[0037] In addition, after the lower edge 11 of the inner container 1 and the upper edge 21 of the base 2 are clamped and fixed, they can be further tightened and fixed by screws, thereby achieving direct fixing.

[0038] With reference to Figure 6 , Figure 7 As described above, the outer side of the lower edge 11 of the inner container 1 is fixedly connected with an upper fixing portion 13, and the upper edge 21 of the base 2 is provided with a lower fixing portion 23, and the upper fixing portion 13 corresponds to the lower fixing portion 23. The inner circumferential portion of the upper edge 21 of the base 2 is recessed at a position corresponding to the lower fixing portion 23, and the upper fixing portion 13 is embedded in the inner side of the lower fixing portion 23.

[0039] A screw hole 131 is formed on the outer side of the upper fixing portion 13, and a screw through hole 231 is formed at a position corresponding to the screw hole 131 of the lower fixing portion 23. During installation, the screw is threaded through the through hole 231 of the lower fixing portion 23 and is screwed with the screw hole 131 outside the upper fixing portion 13, so that the screw can be screwed and fixed, and the inner container 1 and the base 2 can be locked and fixed.

[0040] The embodiment also discloses a dishwasher, which comprises the inner container and base fixing structure in the above-described embodiments, can stably connect the inner container 1 and the base 2 in the dishwasher, can maintain the connection stability between the inner container 1 and the base 2, and can facilitate the assembly of the inner container 1 and the base 2. The inner container and the base are integrally formed of plastic material, and form the inner container and the base, respectively. The inner container is directly sleeved and fixed on the upper portion of the base, the base can close the lower side opening of the inner container, and the inner container and the base form a complete inner container assembly. The inner container and the base are sleeved and embedded with each other, are connected and limited by the clamping structure, and are locked and fixed by the screw, so that the inner container and the base are stably connected and fixed.

[0041] The above merely is preferred implementation manner of the present application, the protection scope of the present application is not only limited to the above examples, and belongs to the technical scheme under the idea of the present application all belongs to the protection scope of the present application.
