Detailed Implementation Methods

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] See appendix Figure 1-2 This application provides a water distribution valve structure, which includes a water distribution valve body 1, a valve cover 2, and a motor base 3. The valve cover and the water distribution valve body are connected to form a water distribution chamber. A sealing ring 4 is provided between the valve cover and the water distribution valve body to improve the sealing performance of the connection between the valve cover and the water distribution valve body, preventing water leakage at the connection point and thus reducing the water pressure in the water distribution chamber. A water distribution lever 5 is rotatably connected in the water distribution chamber. The water distribution valve body is provided with an inlet and multiple outlets communicating with the water distribution chamber. By rotating the water distribution lever, water can be switched at the outlets. The motor base 3... Installed on the valve cover 2 and forming a transmission cavity with it, the transmission cavity is provided with a water distribution shaft 6. The valve cover 2 has a hole 7 for the water distribution shaft 6 to pass through. A shaft sealing ring 8 is provided at the corresponding position of the hole in the transmission cavity. The water distribution shaft 6 is connected to the shaft sealing ring and passes through the hole to connect with the water distribution lever 5. The shaft sealing ring is used to enhance the sealing at the hole 7 to prevent water leakage from the connection between the hole and the water distribution shaft. A drive motor 9 connected to the water distribution shaft 6 is provided on the motor base 3. The drive motor drives the water distribution shaft to rotate, thereby causing the water distribution lever to rotate.

[0021] The valve cover 2 has a step 10 that extends into the water distribution chamber. The sealing ring 4 is fitted on the step to better determine the position of the sealing ring and prevent it from loosening or shifting. The inner wall of the water distribution valve body is provided with a concave step 11 that abuts against the sealing ring. When the valve cover is connected to the water distribution valve body, the sealing performance between the valve cover and the water distribution valve body can be improved by the pressing action of the concave step.

[0022] The outer circumferential distribution of the water distribution valve body 1 has multiple snap-fit ​​parts 12, and the valve cover 2 is provided with snap-fit ​​positions 13 that snap with the snap-fit ​​parts. The snap-fit ​​parts and snap-fit ​​positions snap together to assemble the valve cover and the water distribution valve body together. The snap-fit ​​structure is used to assemble the valve cover and the water distribution valve body, which has the advantages of easy installation and disassembly.

[0023] The valve cover 2 is provided with an annular wall 14 around the hole, and the rotating shaft sealing ring 8 is located on the inner side of the annular wall. The rotating shaft sealing ring is deformed by the annular wall and the water distribution rotating shaft. The deformed rotating shaft sealing ring can improve the sealing performance and further prevent water leakage.

[0024] The motor base 3 is equipped with a micro switch 15, and the water distribution shaft 6 is equipped with a trigger protrusion 16 for triggering the micro switch. The trigger signal of the micro switch allows the dishwasher main control system to determine the position of the water distribution blade.

[0025] The water distribution valve body 1 is provided with a first water outlet 17, a second water outlet 18, and a third water outlet 19. The second water outlet 18 is located on the side wall of the water distribution valve body or at the connection between the side wall and the top wall. The third water outlet 19 is located on the side wall of the water distribution valve body. The water distribution deflector is provided with a first through hole 20, a second through hole 21, and a side baffle 22. Water is supplied to the water outlet of the water distribution valve body by rotating the water distribution deflector. For example, when the water distribution deflector rotates to the point where the side baffle blocks the third water outlet, the second through hole is misaligned with the second water outlet, and the first through hole corresponds to the first water outlet, then only the first water outlet will output water. The specific situation depends on the actual control of the dishwasher and is not limited here.

[0026] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments.
