Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This embodiment discloses a dishwasher top spray structure, referring to... Figures 1-4 As shown, it includes an inner tank 1, a top spray water pipe 2 and a top sprayer 3. The front side of the inner tank 1 is open, and it has an upper side wall 11, a rear side wall 12, a left side wall, a right side wall and a lower side wall, so that the inner tank 1 forms a front-open receiving structure.

[0028] The top spray water pipe 2 is installed on the upper side wall 11 of the inner tank 1. The first end of the top spray water pipe 2 is provided with a water inlet 21, and the second end is provided with a water outlet 22. The water outlet 22 is located on the lower side of the top spray water pipe 2. A top sprayer 3 is installed at the water outlet 22, so that the top sprayer 3 can spray water downward from the top of the inner tank 1.

[0029] The upper sidewall 11 of the inner liner 1 has an upwardly recessed receiving recess 111. The shape of the receiving recess 111 is adapted to the shape of the top spray water pipe 2 and is slightly larger than the outline of the top spray water pipe 2, so that the top spray water pipe 2 can be embedded and installed into the receiving recess 111. At least a portion of the top sprayer 3 protrudes from the receiving recess 111.

[0030] The top spray water inlet pipe 2 has a relatively large width from left to right and a smaller width from top to bottom. The first end of the top spray water inlet pipe 2 faces the rear side wall of the inner tank 1 and is close to the rear side wall of the inner tank 1. The first end of the top spray water inlet pipe 2 bends downward to form an elbow, so that the water inlet 21 can face and connect with the water passage installed on the rear side wall of the inner tank.

[0031] The second end of the top spray water pipe 2 extends to the middle of the upper side wall 11 of the inner tank 1. That is, the outlet 22 of the second end of the top spray water pipe 2 is located approximately in the middle of the upper side wall of the inner tank 1, so that the top sprayer 3 can be located approximately in the middle of the top of the inner tank 1, and can spray more evenly.

[0032] The top spray water pipe 2 is connected and fixed to the upper side wall 1 of the inner tank 1 by screws 4. A connecting block 201 is fixedly connected to the outside of the top spray water pipe 2. The connecting block 201 is fixedly connected to the upper side of the receiving recess 111 and fits and positions itself.

[0033] A through hole 202 is provided in the connecting block 201, and a screw hole 112 is provided on the upper side of the recess 111. The screw hole 112 and the through hole 202 are vertically opposite each other. When the screw 4 is installed, it passes through the through hole 202 and is threadedly connected and fixed to the screw hole 112. The screw head of the screw 4 is located on the lower side of the through hole 202, which can achieve thread tightening and fixing.

[0034] Specifically, a connecting post 113 is fixedly connected to the outer side of the upper side wall 11 of the inner liner 1. The connecting post 113 is positioned opposite to the screw hole 112. The screw hole 112 extends into the connecting post 113, so that the screw hole 112 can have a certain depth, which can improve the stability and strength of the threaded connection.

[0035] Reference Figure 3 As shown, the top sprinkler 3 is equipped with a buckle 33, and a buckle block 203 is fixedly connected to the outside of the top spray water pipe 2. The buckle 33 has a buckle interface, which can be snapped and fixed with the buckle block 203, thereby enabling the top sprinkler 3 to be installed and fixed.

[0036] The top sprayer 3 is divided into two parts: a spray base 31 and a rotating spray element 32. The spray base 31 is fixedly installed at the outlet 22 of the top spray water pipe 2, and the rotating spray element 32 is rotatably connected to the lower side of the spray base 31. The rotating spray element 32 is roughly disc-shaped, with an opening on its outer side, allowing it to rotate and spray water onto the outer periphery of the rotating spray element 32. Furthermore, the opening of the rotating spray element 32 rotates outward from the center, and during the spraying process, the force of the water flow drives the rotating spray element 32 to rotate, thereby realizing the rotating spraying action.

[0037] Reference Figure 4 As shown, the rotating spray member 32 is partially embedded in the receiving recess 111 and partially protrudes downward outside the receiving recess 111. The opening on the outer periphery of the rotating spray member 32 can protrude out of the receiving recess 111 and is located on the lower side of the upper sidewall 11, so as to avoid being blocked by the receiving recess 111 during the spraying process.

[0038] This embodiment also discloses a dishwasher, including the dishwasher top spray structure as described above, as well as an inner tank, a water cup, a spray arm, and other structures, which can realize spray washing of the dishwasher inner tank.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
