Fig. 1 is a schematic perspective view of a water pump, fig. 2 is a schematic sectional view of the water pump, and fig. 3 is a schematic view of a valve of the water pump of the present invention, as shown in fig. 1, fig. 2, and fig. 3:
the water pump 1 comprises a pump cavity 2, an impeller 4 arranged in the pump cavity 2 and driven by a motor 3, and a water inlet channel 5, a circulating water channel 6 and a drainage channel 7 which are communicated with the pump cavity 2 in a fluid manner; wherein, the motor is provided with a rotating shaft 8 to drive the impeller 4, fluid such as water enters the pump cavity 2 through the water inlet channel 5, and the circulating water channel 6 and the drainage channel 7 are communicated with the pump cavity 2.
A valve 9 is arranged in the pump chamber 2, said valve 9 being provided with an opening 10, and the valve 9 being movable between a first position and a second position.
Fig. 4 is a schematic view (one) of the operation of the valve of the water pump in the pump chamber, and as shown in fig. 4, in a first position, the opening 10 is opposite to the circulating water passage 6, so that the circulating water passage 6 is in fluid communication with the pump chamber 2 and the water inlet passage 5, and the water outlet passage 7 is separated from the pump chamber 2 by the valve 9.
Fig. 5 is a schematic view (two) of the operation of the pump valve in the pumping chamber, and as shown in fig. 5, in the second position, the opening 10 is opposite to the water discharge passage 7, so that the water discharge passage 7 is in fluid communication with the pumping chamber 2 and the water inlet passage 5, and the water circulation passage 6 is isolated from the pumping chamber 2 by the valve 9.
With the above structure, when the washing machine operates, water enters the pump chamber 2 from the water inlet passage 5. When the washing machine is to be operated with internal water circulation, the valve 9 is in a first position, with the opening 10 opposite the circulation water channel 6, and water is discharged from the pump chamber 2 into said circulation water channel 6. When the washing machine requires a drain operation, the valve 9 is in the second position, with the opening 10 opposite the drain channel 7, and water is drained from the pump chamber 2 into said drain channel 7. The water pump realizes two functions of water circulation and water drainage by different positions of one valve.

Preferably, the inner wall of the pump chamber 2 is provided with two projections 13a and 13b, one of which 13a is intended to define the valve 9 in a first position and the other 13b is intended to define the valve 9 in a second position, as described in the above solution, when the projection 13b meets a stop face 14b on one side of the projection 12 on the outer wall 9b of said valve.
Preferably, in an embodiment not shown in the other figures, the stop means may comprise a projection provided on the inner wall of the pump chamber and a groove provided on the outer wall of the valve cooperating with the projection, the groove extending circumferentially and having two stop surfaces at the ends. When the protrusion hits the blocking surface, the valve will be restricted to this position, which may be the first position or the second position in the above solution, where water circulation or draining is possible. Another conceivable alternative is to provide the pump chamber with a recess having a blocking surface and the valve outer wall with a projection, which likewise defines the position of the valve.
Preferably, the pump cavity 2 has a cylindrical side wall 21 and an end wall 22 at one end of the cylindrical side wall, the water discharge passage 6 and the circulating water passage 7 are connected to the cylindrical side wall 21, and the water inlet passage 5 is connected to the end wall 22 of the pump cavity. The design makes the space of the water pump more compact, and the efficiency of realizing water circulation or drainage work is higher.
