In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

In order to prevent the water overflowing from the air vent from flowing back into the cup, in the related art, as shown in fig. 2, an air vent X on the drain pump 1 is not connected to the cup (not shown), but an air vent Y extending upward is additionally provided to be connected to the air vent X, so as to directly vent air to the water through the air vent Y. However, in order to prevent water from overflowing the exhaust pipe Y, a water leakage problem occurs in the dishwasher. The extension height of the exhaust pipe Y will depend on the lift of the drain pump 1, so that the exhaust pipe Y needs to extend upward for a certain length, thereby increasing the occupied space and being not beneficial to practical application.

Referring to fig. 3, a water drainage structure of a dishwasher provided in an embodiment of the present application includes a water drainage pump 1, a three-way pipe 2, a first connection pipe 3, and a second connection pipe 4.

The drain pump 1 is disposed on a cup (not shown) of the dishwasher, and a pump case of the drain pump 1 is provided with a drain port 11 and an exhaust port 12. Wherein the exhaust port 12 is higher than the drain port 11.

One end of the second connection pipe 4 is connected to the second inlet 22, and the other end of the second connection pipe 4 is connected to the exhaust port 12 of the drain pump 1.

Therefore, the water drainage structure of the water cup can realize water drainage and remove trapped air in the water drainage pump 1, and effectively solves the problem that water liquid in the water drainage pump 1 flows back to the water cup due to the fact that the water cup is provided with the exhaust hole communicated with the pump shell of the water drainage pump 1.

Compared with the prior art, the drainage structure of dish washer drinking cup that this application embodiment provided, add three-way pipe 2 outside the drinking cup, two connecting pipes through independent setting are connected between this three-way pipe 2 and the drain pump 1, these two independent connecting pipes include first connecting pipe 3 and second connecting pipe 4, this first connecting pipe 3 and second connecting pipe 4 correspond respectively and connect outlet 11 and gas vent 12 on the pump case of drain pump 1, can enough realize the drainage, can get rid of the stranded gas in the drain pump 1 again. In particular, the water possibly overflowing from the exhaust port 12 of the drain pump 1 can be returned to the three-way pipe 2 through the second connection pipe 4 and discharged. Therefore, the water in the drainage pump 1 is prevented from flowing back to the water cup due to the fact that the drainage hole is formed in the water cup; or, the water is prevented from directly flowing out of the dishwasher after seeping out of the air exhaust holes, so that the water leakage accident of the dishwasher is avoided, and the quality of the dishwasher is effectively improved.

In addition, compare with above-mentioned correlation technique, this second connecting pipe 4 is as the blast pipe, through three-way pipe 2 toward outer exhaust, can also be simultaneously with the water liquid that overflows from the gas vent 12 of drain pump 1, unitedly converge to three-way pipe 2 in the discharge that gathers, and then eliminate the occupation space that sets up the blast pipe that upwards extends, reduce the structure volume on the drinking cup effectively, improve the space utilization to dish washer inside.

Referring to fig. 4, the drain port 11 of the drain pump 1 is preferably disposed to be two times or more larger than the drain port 12. It can be seen that, since the air vent 12 is disposed near the top of the pump housing of the drainage pump 1 and higher than the drainage port 11, and the drainage port 11 is much larger than the air vent 12, the water flow in the drainage pump 1 is mainly discharged to the drainage port 11, thereby improving the drainage effect.

In addition, the air outlet 12 is preferably disposed near the top of the pump housing of the drain pump 1, so that the air stored in the drain pump 1 is mainly located at the top of the pump housing, and the air outlet 12 is disposed on the pump housing corresponding to the position, so that the air in the drain pump 1 can be discharged in time, and the air trapping problem of the drain pump 1 is effectively solved.

Specifically, referring to fig. 3 and 4, a pump housing of the drain pump 1 has a first connector 13 connected to the drain port 11 and a second connector 14 connected to the exhaust port 12, the first connector 13 is connected to the first connection pipe 3, and the second connector 14 is connected to the second connection pipe 4. Therefore, the installation and connection of each connecting pipe are facilitated, or a possible sealing structure is conveniently arranged, for example, a sealing ring is arranged on the connecting part, so that the connecting and fixing effect of each connecting pipe is effectively improved, and the sealing performance is improved.

In the present embodiment, referring to fig. 4, the first connector 13 and the second connector 14 both extend outward from the side of the pump casing of the drain pump 1. Since the drainage pump 1 is disposed at the bottom of the cup, the first connector 13 and the second connector 14 extend outward from the side of the drainage pump 1 to avoid interference with the structure above the top of the drainage pump 1, thereby improving the utilization rate of the space.

The first connector 13 and the second connector 14 are disposed in parallel up and down to avoid mutual interference and effectively improve the smoothness of drainage and exhaust. In the present embodiment, referring to fig. 3 and 4, since the drain pump 1 configured with the synchronous motor is adopted, the drain port 11 needs to be disposed corresponding to the middle position of the drain pump 1, so as to match the operation characteristics of the synchronous motor. Thus, the first connection head 13 is located at the middle of the pump case and is communicated with the drain port 11 of the drain pump 1.

In this embodiment, it is preferred to use a tee 2 that is at a height higher than the set height of the drain pump 1, i.e., a H1 value higher than the H2 setting as shown in fig. 5. Let second connecting pipe 4 for exhaust air can promote gradually toward the direction of three-way pipe 2, and then the upward flow characteristic of cooperation air improves exhaust efficiency effectively.

Specifically, please refer to fig. 6, the three-way pipe 2 is a bent pipe, the three-way pipe 2 includes a transverse pipe 24 and a vertical pipe 25 which are integrally connected, an extending pipe 26 is provided on a bent portion of the three-way pipe 2, an outward extending port of the transverse pipe 24 is an output port 23, an outward extending port of the vertical pipe 25 is a first input port 21, an outward extending port of the bent pipe is a second input port 22, the first input port 21 and the second input port 22 are located on one side of the three-way pipe 2, and the output port 23 is located on the other side of the three-way pipe 2. Let one side of three-way pipe 2 receive rivers and air respectively, rivers will flow to delivery outlet 23 naturally, also can be with the air of following drain pump 1 exhaust through delivery outlet 23 to the outside. The second input port 22 can also collect the water possibly overflowing from the exhaust port 12 in the tee pipe 2, so that the overflowed water and the discharged water are discharged together.

Wherein the vertical pipe 25 is extended downward so that the first input port 21 is located at a lower level than the second input port 22. On the one hand, the water flow is admitted from the first inlet 21, which is located at a lower level, and is discharged by the motor of the drain pump 1. On the other hand, the air in the drain pump 1 is introduced from the second input port 22 at the high level to discharge trapped air in the drain pump 1 in accordance with the flow characteristics of the air.

Preferably, referring to fig. 6, the transverse tube 24 is coaxially aligned with the extension tube 26 such that the outlet port 23 is disposed opposite the second inlet port 22. Accordingly, as the air in the drain pump 1 flows toward the extension pipe 26 through the second connection pipe 4, the air enters the three-way pipe 2 from the extension pipe 26 and is directly discharged from the output port 23 of the transverse pipe 24, thereby improving the smoothness of the air flow. Meanwhile, if the water overflowing from the exhaust port 12 exists in the drain pump 1, the water can flow from the second connecting pipe 4 to the extending pipe 26, and is collected with the discharged water in the three-way pipe 2, and then is uniformly discharged from the output port 23 of the transverse pipe 24, so that the water is prevented from flowing outwards, and the overflow problem of the exhaust port 12 on the drain pump 1 is effectively solved.
