At present, a washing pump of a dish washer in the prior art is usually powered by an alternating current power supply, and the alternating current washing pump has the characteristics of low cost, easiness in control and the like, and meanwhile, the washing pump has the characteristic of non-adjustable rotating speed.

However, the washing of the dish washer generally includes two stages, namely, washing and rinsing, the water pressure requirements of the two stages are not consistent, the water pressure required in the washing stage is greater than that in the rinsing stage, if the water pressure in the rinsing stage is too high, a large amount of secondary pollution is easily caused, and if the water pressure in the washing stage is insufficient, the washing stage is difficult to clean. The AC washing pump has the problem that the water pressure of the spray arm is unchanged in the whole washing stage because the rotating speed is not adjustable, and the washing and rinsing effects are difficult to ensure.

In addition, during the washing process of the dish washer, a large amount of foam is generated due to the chemical action of the detergent with stains on the surface of the dish, and the foam is continuously increased with the extension of the washing time. When excessive foam participates in washing, a large amount of foam not only consumes the water quantity in the dishwasher when the water inflow is fixed; in addition, if too much foam is pumped into a water path system by a washing pump in a washing stage, washing operation is unstable after water vapor is mixed, and further the washing pump is low in power and fluctuates up and down, so that the efficiency of the washing pump is reduced, the water pressure sprayed from a spray nozzle of a sprayer is reduced, and the damage caused visually is the deterioration of the washing capability of the dish washer.

Specifically, the boss 13 is provided on the first inner wall of the pumping channel 11.

Specifically, the rotating shaft 30 is rotatably disposed relative to the protruding portion 13, and the protruding portion 13 also plays a limiting role on the rotating shaft 30, so that the rotating shaft 30 rotates within a preset rotation angle range.

As shown in fig. 1 and 2, the baffle 20 has a first end surface 21 and a second end surface 22 disposed opposite to each other, and the dishwasher further includes: the telescopic part 40 is connected with the base 10, the telescopic part 40 is used for being propped against the second end face 22, and the telescopic part 40 is arranged telescopically relative to the base 10 so as to drive the deflector 20 to rotate relative to the base 10. The dish washer can change the flow area of the water pumping channel 11 by changing the different rotation angles of the guide plates through the extension and contraction of the extension and contraction part 40, thereby achieving the purpose of flow restriction.

In this embodiment, the dishwasher further includes a driving device 50, the driving device 50 being mounted on the base 10, the driving device 50 including a driving body and a telescopic rod telescopically disposed on the driving body; the telescopic rod is a telescopic part 40.

Alternatively, the drive 50 is a wax motor.

Specifically, the driving device 50 is located outside the base 10.

As shown in fig. 2, the base 10 is provided with a mounting hole 14, the telescopic portion 40 is inserted into the mounting hole 14, and a seal 90 is provided between the telescopic portion 40 and the mounting hole 14. Wherein the seal 90 is a sealing ring. The seal 90 serves to prevent leakage of the washing water from the outside of the dishwasher.

Optionally, a flexible member is disposed on the telescopic portion 40, and the telescopic portion 40 abuts against the second end face 22 through the flexible member. The flexible member is made of a flexible material and this arrangement avoids wearing the telescoping portion 40 and the baffle 20.

Such an arrangement enhances the mechanical strength of the baffle.

Optionally, a plurality of first reinforcing ribs 60 are disposed on the first end surface 21 at intervals; a plurality of second reinforcing ribs 70 are provided at intervals on the second end face 22.

As shown in fig. 2, the rotation angle of the baffle 20 is 0 ° to 20 °, and when the rotation angle of the baffle 20 is 0 °, the flow area of the water pumping channel 11 is S; when the rotation angle of the baffle 20 is 20 degrees, the flow area of the pumping channel 11 is S/2. The position of the deflector 20 at two angles of rotation is shown in fig. 2. Specifically, the baffle 20 is connected to the first inner wall of the pumping channel 11, and when the rotation angle of the baffle 20 is 0 °, the baffle 20 is parallel or nearly parallel to the axis of the pumping channel 11; after the deflector 20 rotates, the deflector 20 is obliquely arranged in the pumping channel 11, i.e. the deflector 20 is obliquely arranged with the axis of the pumping channel 11.

In this embodiment, the water pumping channel 11 is in communication with the washing chamber of the dishwasher; the dishwasher further includes: the water pumping pipe 80 of the washing pump is communicated with the water pumping channel 11, and the water draining pipe of the washing pump is communicated with the spray arm, so that the washing water in the washing cavity flows to the spray arm after passing through the water pumping channel 11 under the action of the washing pump. Specifically, the wash pump is an ac pump.

In particular, the dishwasher requires a high water pressure during the washing stage so that the spout has a sufficiently high water pressure to flush dirt off the dish, while the wash pump water-pumping channel widens to reduce the flow rate, and foam is not easily pumped into the wash pump to cause power fluctuation of the wash pump. In the rinsing stage, smaller water pressure is needed to make the water pressure of the nozzle soft, so that secondary pollution is avoided. The application solves the problem that the rotating speed of the alternating current pump is not adjustable and the water pressure of the spray arm cannot be changed.

In particular, after the dishwasher enters a washing stage, the wax motor is electrified, the telescopic part 40 is contracted, the water pumping channel 11 is fully opened to provide enough water supply to improve the water spraying pressure of the spray arm, the flow velocity in the fully opened water pumping channel is reduced, and the water flow can be prevented from bringing foam into the washing pump to cause power fluctuation. When the dishwasher enters the rinsing stage, the wax motor is powered off, the telescopic part 40 extends out, the deflector throttles half the flow, and the water spray pressure of the spray arm is reduced to improve the rinsing effect.

The application has the beneficial effects that the flow area of the water pumping channel 11 is adjusted by arranging the guide plate 20, so that the water pumping quantity can be adjusted, the water pressure of the spray arm is adjustable, the water pressure needs to be increased in the washing stage, meanwhile, the water inlet does not need to have high flow velocity to prevent foam floating on the water surface from being pumped into the washing pump to make the washing pump operate unstably, the rinsing stage needs to reduce the water pressure to increase the rinsing softness, and meanwhile, the water pumping speed needs to be higher, so that fine pollutants can be brought into the water cup as soon as possible by the water flow and are discharged along with the water discharge.
