Description
Technical Field
[0001] The utility model relates to the field of kitchen appliances, in particular to a water diverter valve for a dishwasher. Background Art
[0002] A dishwasher is a kitchen appliance used to automatically wash dishes, and is gradually entering more and more ordinary households. Before the old dishwasher is running, the user needs to place the bowls in the dishwasher with the mouth of the bowl facing a fixed direction, so that the water in the dishwasher can wash away the stains in the mouth of the bowl, but the cleaning effect on the bowl body is not good; the improved dishwasher has four spray directions by setting up an upper spray arm, a left spray arm, a right spray arm and a lower spray arm in the four directions of up, down, left and right in the dishwasher, so that the dishes placed in the dishwasher can be completely covered by the water flow.
[0003] During the washing process, the improved dishwasher needs to operate the four water spraying directions separately, otherwise the water spraying in two directions will impact each other, reducing the cleaning effect of the water flow. The four water spraying directions alternately spray water flow by connecting the upper spray arm, the left spray arm, the right spray arm and the lower spray arm to the water diversion valve, so that the water diversion valve can adjust the water flow.
[0004] However, when switching the water spraying direction, the above-mentioned water diverter valve will first cut off the water flow in one of the water spraying directions, and then supply the water flow to the other water spraying direction; therefore, when switching the water spraying direction, the internal water flow of the water diverter valve will not be discharged, and the water flow will form a large pressure inside. Excessive pressure will cause the water diverter valve to be damaged and leak. Utility Model Content
[0005] The utility model aims to provide a water diverter valve for a dishwasher, which can reduce the internal pressure of the water diverter valve when switching the water spraying direction.

[0041] Assembly of this water diverter valve:
[0042] The two second waterproof rings 123 are respectively sleeved in the two annular grooves of the water diverter 12. The water diverter 12 is placed in the first cavity 111 of the valve body 11. The two second waterproof rings 123 can prevent the water flowing from the gap 122 to the water outlet 112 from leaking out from the gap between the first cavity 111 and the water diverter 12. The central axis 124 of the water diverter 12 passes through the other end of the valve body 11, and the first waterproof ring 113 is sleeved on the outer side of the annular step.
[0043] After the spring 116 is placed in the first cavity 111, the cover plate 14 is placed on one end of the valve body 11, so that the annular step is inserted into the installation groove, and the outer side of the first waterproof ring 113 touches the inner wall of the installation groove.

[0045] The water inlet 141 is connected to an external water pipe, and the external water pipe injects water into the second cavity 121 through the water inlet 141; the four water outlets 112 are respectively connected to an external upper spray arm, an external left spray arm, an external right spray arm and an external lower spray arm.
[0046] The operation process of this water diverter valve;
[0047] When the water outlet 112 is switched, the output shaft of the motor 2 drives the first pulley 21, the transmission belt 22, the second pulley 13 and the central axis 124 to rotate in sequence, thereby driving the water diverter 12 to rotate in the first cavity 111; during the process of the water diverter 12, the connection between the gap 122 and one of the water outlets 112 gradually becomes smaller, while the gap 122 is connected to the other water outlet 112, and the connection between the gap 122 and the other water outlet 112 gradually becomes larger, so that the water flow inside the water diverter valve is always in a flowing state; when the water diverter 12 is rotated into place, the connection between the water diverter 12 and one of the water outlets 112 is closed, and the connection between the water diverter 12 and the other water outlet 112 is completely opened.
[0048] The utility model provides a dishwasher water diverter valve, wherein a water inlet is connected to an external water pipe so that the external water pipe can inject water into a second cavity through the water inlet, and an output shaft of a motor drives a water diverter to rotate through a central shaft so that a notch is sequentially close to each water outlet, so that water in the second cavity can be sequentially discharged from the notch and the water outlets adjacent to the notch; since when the notch is connected to one of the water outlets, an edge of the notch is close to another adjacent water outlet, but the notch is not connected to another adjacent water outlet, when the water diverter rotates to switch the water flow to be discharged from another water outlet, the notch will gradually reduce the diameter of the connection with one of the water outlets, and the edge of the notch will immediately connect with another adjacent water outlet, and gradually increase the diameter of the connection between the notch and the other adjacent water outlet; so that when the device switches the water outlet to discharge water through the water diverter, water can be discharged through the two water outlets at the same time, so that the internal pressure of the water diverter valve is constant.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
