Advantageously, as shown in fig. 3, the drain port of the suction pump 70 and the suction pipe 60 may be connected by a hose clamp 901 to improve the reliability and stability of the connection.

With respect to filter 10, as shown in fig. 6-11, filter 10 may include a filter housing 110, a filter cup 120, and a filter element 130.

Specifically, the filter housing 110 has a first water inlet 111 and a first water outlet (not shown in the drawings). The filter cup 120 is used for performing primary filtration on water entering the filter housing 110, the filter core 130 is used for performing secondary filtration on the water subjected to the primary filtration, the filter core 130 is detachably mounted in the filter housing 110, the filter cup 120 is detachably mounted on the peripheral wall of the filter core 130, the filter core 130 and the filter cup 120 are both provided with a plurality of filter holes 101, the filter cup 120 is provided with a second water inlet 121 corresponding to the first water inlet 111, and the end wall of the filter core 130 is provided with a second water outlet 131 corresponding to the first water outlet.

filter material

124, 50% of graphite and 50% of silicon carbide ceramic foam are included.

Therefore, when the washing machine 1 discharges water, under the action of the drainage pump 90, the wastewater enters the filter 10 through the first water inlet 111, enters the filter cup 120 through the first water inlet 121, enters the filter core 130 through the filter holes 101 of the filter cup 120 after being subjected to the primary filtration of the filter cup 120, then flows out of the filter core 130 through the filter holes 101 and the second water outlet 131 of the filter core 130 respectively after being subjected to the primary filtration, completes the secondary filtration of the water, and finally flows out of the filter 10 through the first water outlet, and is discharged out of the washing tub 30 through the drainage pipe 50 of the washing machine 1 to flow into the water tank 40. During the above two-stage filtration of water, the lint and foreign substances in the waste water are caught by the filter cup 120 and the filter element body 130 and remain in the filter 10, thereby preventing the lint from being entangled with the blades of the drain pump 90 or blocking the drain pipe 50.

Preferably, an alarm device may be provided on the washing machine 1, for example, a water level detecting device may be provided in the washing machine 1, so that when the filter 10 is too much to block the filter hole 101, and the water flow cannot flow out normally, the alarm device gives an alarm, and at this time, the user only needs to take out the filter cup 120 and the filter element 130 from the filter housing 110 and clean the filter cup, and the washing machine 1 can continue to be used, thereby facilitating the use and cleaning of the user.

According to some embodiments of the present invention, as shown in fig. 6 to 8, the upper end of the filter cup 120 is opened to form the first water inlet 121, thereby allowing water to smoothly flow into the filter 10 by gravity. Further, the central axis of the first water inlet 121 is perpendicular to the central axis of the second water outlet 131, so that water can fully flow through the filter cup 120 and the filter holes 101 on the filter element body 130 for filtering, the filtering path of the water is extended, and the filtering effect is improved.

Advantageously, as shown in fig. 7 and 8, the central axis of the first water inlet 121 is oriented along the radial direction of the filter element 130, and the central axis of the second water outlet 131 coincides with the central axis of the filter element 130, so that the filtering effect of the filter 10 is further enhanced, and the processing is convenient.

According to some embodiments of the present invention, the filter cup 120 and the filter core 130 may be made of a filter net, so as to simplify the manufacturing process and simplify the structure. For example, the filter screen may be a steel wire filter screen or a nylon filter screen.

In the embodiment shown in fig. 7 and 9, filter 10 may further include a knob 140, knob 140 being rotatably mounted on filter housing 110, and filter core 130 being removably mounted on knob 140. Therefore, when the filter shell 110 is full of flocks and impurities, the knob 140 can be conveniently unscrewed, the filter cup 120 and the filter core body 130 can be drawn out from the filter shell 110, the filter core body 130 can be detached from the knob 140, the filter cup 120 can be detached from the filter core body 130, and the filter cup 120 and the filter core body 130 can be cleaned.

Alternatively, as shown in fig. 7 and 9, the knob 140 is screwed to the filter housing 110 and the filter core 130, respectively, so as to further simplify the structure of the filter 10 and facilitate the assembly and disassembly. For example, the outer peripheral wall of the knob 140 is respectively provided with a first screw 141 and a second screw 142, the knob 140 is screwed with the filter housing 110 through the first screw 141, and the filter element body 130 is screwed with the knob 140 through the second screw 142. The first thread 141 and the second thread 142 are external threads, respectively, and the threads on the filter housing 110 and the filter element 130 are internal threads, respectively. Preferably, the knob 140 is located at a rear side surface of the body of the washing machine 1, so that a user's operation is facilitated and the aesthetic appearance of the washing machine 1 can be improved.
