[0025] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] See Figures 1 - 7 , the main body sealing structure of this dishwasher dispenser includes an upper base shell 1 and a lower base shell 2. The upper base shell 1 and the lower base shell 2 are connected and fixed to form an electrical cavity for installing electrical components. By setting the independent upper base shell 1 and lower base shell 2, it is more convenient to install the electrical components in the electrical cavity.

[0027] A sealing ring 3 is provided at the position corresponding to the periphery of the electrical cavity between the upper base shell 1 and the lower base shell 2. The sealing ring 3 is closely matched with the upper base shell 1 and the lower base shell 2 respectively. The sealing ring 3 can reduce the chance of external liquid entering the electrical cavity, play a better protective effect on the electrical components, and extend the service life of the dishwasher dispenser.

[0028] Furthermore, a limiting part corresponding to the sealing ring 3 is provided in the upper base shell 1. The limiting part is arranged along the circumferential direction of the electrical cavity. The sealing ring 3 is connected and fixed to the limiting part, which improves the installation accuracy of the sealing ring 3, makes the sealing ring 3 not easy to shift during use, and thus improves the sealing strength between the upper base shell 1 and the lower base shell 2.

[0029] Furthermore, the limiting part includes a plurality of clamping ribs 11 distributed along the circumferential direction of the electrical cavity. The clamping ribs 11 can improve the overall structural strength of the upper base shell 1.

[0030] A U-shaped groove 111 corresponding to the sealing ring 3 is provided on the clamping rib 11. The opening of the U-shaped groove 111 faces the lower base shell 2. The sealing ring 3 is clamped into the U-shaped groove 111 from the opening of the U-shaped groove 111. The connection structure between the sealing ring 3 and the U-shaped groove 111 is simple, and there is no need to fix the sealing ring 3 with additional substances such as adhesives, which improves the installation efficiency and reduces the installation cost.

[0031] Furthermore, the limiting part also includes a bottom perimeter 12. The bottom perimeter 12 is arranged along the circumferential direction of the electrical cavity. The bottom perimeter 12 is sequentially connected to different clamping ribs 11 to form an integral body. The side of the bottom perimeter 12 facing the lower base shell 2 is flat and flush with the side of the U-shaped groove 111 facing away from the opening. The bottom perimeter 12 can improve the structural strength between different clamping ribs 11, make the overall structural strength of the upper base shell 1 better, and the bottom perimeter 12 does not affect the normal installation connection between the sealing ring 3 and the U-shaped groove 111.

[0032] Furthermore, the limiting part further includes several side enclosing edges 13 which are arranged along the circumference of the electrical cavity. The side enclosing edges 13 are respectively connected to different clamping ribs 11 in sequence to form a whole. The side of the side enclosing edge 13 facing the lower base shell 2 is flat and flush with the opening side of the U-shaped groove 111, which further improves the structural strength between different clamping ribs 11, makes the overall structural strength of the upper base shell 1 better, and the side enclosing edge 13 will not affect the normal installation and connection between the lower base shell 2 and the upper base shell 1.

[0033] Furthermore, on the side of the lower base shell 2 facing the upper base shell 1, there is a contact platform 21 corresponding to the position of the limiting part. The contact platform 21 is arranged along the circumference of the electrical cavity. The contact platform 21 is in close fit with the sealing ring 3 and the limiting part respectively, so that the lower base shell 2 can have a larger contact area with the sealing ring 3 and the contact part, thereby making the sealing structure between the upper base shell 1 and the lower base shell 2 more stable.

[0034] Furthermore, the side of the contact platform 21 facing away from the upper base shell 1 is hollowed out and distributed with several reinforcing ribs 22. The reinforcing ribs 22 are integrally formed with the upper base shell 1, which improves the overall structural strength of the lower base shell 2.

[0035] Furthermore, several positioning grooves 23 are distributed at the positions corresponding to the periphery of the electrical cavity on the lower base shell 2. There are positioning studs 14 corresponding to the positioning grooves 23 on the upper base shell 1. The positioning studs 14 are in plug-in fit with the positioning grooves 23, which improves the installation accuracy between the upper base shell 1 and the lower base shell 2, thereby making the assembly efficiency higher and the connection stability between the upper base shell 1 and the lower base shell 2 better.

[0036] Furthermore, on the side of the positioning groove 23 facing away from the upper base shell 1, there is a screw hole 231. There is a screw groove 141 corresponding to the screw hole 231 on the positioning stud 14. The screw hole 231 and the screw groove 141 are connected and fixed by a screw device 4 to install and fix the upper base shell 1 and the lower base shell 2. The screw device 4 can be installed by using the spatial positions of the positioning groove 23 and the positioning stud 14 to achieve the installation and fixing effect of the upper base shell 1 and the lower base shell 2.

[0037] The above embodiments are only the preferred solutions of the present invention, and the present invention may have other implementation solutions. Those skilled in the art can also make equivalent deformations or replacements without departing from the spirit of the present invention, and these equivalent deformations or replacements are all included within the scope set by the claims of this application.
