Background

The existing drum washing machine is generally provided with a drain pump. When the drum washing machine drains water, the drain pump pumps the washing water in the outer drum to the outside. Some lint is often present in the wash water from which the laundry is washed. In order to prevent the lint from being entangled with the impeller of the drain pump, a filter is provided at the water inlet of the drain pump.

The existing filters mainly comprise a filtering hole type filter and a filtering comb type filter.

The filtering hole type filter is provided with a plurality of filtering holes. The filtering holes only allow the washing water to pass through, but not allow the thread scraps to pass through, thereby achieving the purpose of filtering the washing water. But during prolonged use, some of the thread crumbs will be inserted and stuck into the filter holes. When the user is clearing up the filter, not only need clear up whole filter, but also need manually pull out the line bits in the filtration pore, user's clearance physical examination is relatively poor.

With continued reference to fig. 1 to 4, the filter device of the present invention mainly includes a housing 1, a cover 2, a filter member 3, and a cleaning member 4.

As shown in fig. 1 and 2, the housing 1 is provided with an inlet pipe 11 and an outlet pipe 12. Wherein, a water inlet channel 111 is formed in the water inlet pipe 11, and a water outlet channel 121 is formed in the water outlet pipe 12.

As shown in fig. 3 and 4, a cavity 13 is formed in the housing 1, and the cavity 13 is communicated with the water inlet passage 111 and the water outlet passage 121, respectively. The cavity 13 is used to accommodate the filter element 3 and the cleaning element 4.

With continued reference to fig. 3 and 4, housing 1 is also provided with mounting holes (not shown) that communicate with cavity 13. Be provided with the internal thread on the mounting hole, be provided with on the lid 2 with the external screw thread that the internal thread matches, lid 2 passes through the internal thread with the meshing detachably of external screw thread is installed in the mounting hole. Preferably, a sealing member is provided on an inner end (a left end of the cover 2 in fig. 3) of the cover 2, and when the cover 2 is screwed to the housing 1, the cover 2 presses the housing 1 by the sealing member, preventing the washing water in the housing 1 from overflowing from the mounting hole. The sealing member may be any feasible sealing member, such as a rubber sealing ring, a plastic gasket, a resin gasket, etc.

As shown in fig. 5 and 6, one axial end of the filter element 3 is fixedly connected to the inner end of the cover 2, so that the filter element 3 is supported in the cavity 13 when the cover 2 is mounted in the mounting hole, and the filter element 3 is removed from the cavity 3 when the cover 2 is removed from the mounting hole. Further, the filter member 3 and the lid body 2 may be integrally formed as needed by those skilled in the art.

With continued reference to fig. 5 and 6, the filter member 3 is of an arcuate cylindrical configuration and the inner side of the filter member 3 is provided with a plurality of raised structures 31 parallel to one another. Preferably, each projection 31 is perpendicular to the axial direction of the filter element 3. Further, the filter member 3 is provided with a first U-shaped opening 32 in the radial direction. Wherein the axis of the first U-shaped mouth 32 is perpendicular to the axis of the projection structure 31. As shown in fig. 3, in the installed state, the first U-shaped mouth 32 is aligned with the water inlet passage 111 so that the washing water in the water inlet passage 111 can enter the inside of the filter member 3 through the first U-shaped mouth 32 to wash the plurality of projection structures 31.

It will be understood by those skilled in the art that the shape of the projection structure 31 is not limited to the columnar structure shown in fig. 3 and 4, but may be a needle-like structure, a tapered structure, a plate-like structure, or the like. The shape of the filter member 3 is not limited to the arc-shaped cylindrical structure, but may be any other feasible shape such as a plate shape, a tub made of a metal mesh, etc.

It can be understood by those skilled in the art that the plurality of convex structures 31 may be arranged at equal intervals or may be arranged at unequal intervals.

With continued reference to fig. 5 and 6, cleaning element 4 is also of arcuate cylindrical configuration and cleaning element 4 is provided with a plurality of through holes 41. Preferably, the number of the through holes 41 is equal to the number of the protruding structures 31, and the diameter of the through holes 41 is slightly larger than the diameter of the protruding structures 31, so that the plurality of protruding structures 31 can respectively pass through the plurality of through holes 41 to attach the cleaning member 4 and the filter member 3 to each other in the radial direction. Further, the cleaning member 4 is provided with a second U-shaped opening 42 aligned with the first U-shaped opening 32 in the radial direction. The second U-shaped port 42 is for allowing the washing water in the water inlet passage 111 to smoothly wash over the plurality of convex structures 31. Still further, the axial end of the cleaning element 4 close to the cover 2 is provided with a handle 43. The cleaning element 4 attached to the filter element 3 can be removed by the user by operating the handle 43.

It will be understood by those skilled in the art that the number of through holes 41 in the cleaning member 4 may be set to be less than the number of the protruding structures 31, and then one through hole 41 may simultaneously receive at least two protruding structures 31.

It will also be understood by those skilled in the art that the shape of the cleaning element 4 is not limited to the arcuate cylindrical configuration, and that it may be adjusted appropriately according to the shape of the filter element 3.

As shown in fig. 3 and 4, the drain valve of the present invention further includes a motor 5, a plunger 6, and a bellows 7. The cavity 13 in the housing 1 is divided into two parts, a right part for accommodating the filter member 3 and the cleaning member 4, and a left part for accommodating the plunger 6 and the bellows 7.

As shown in fig. 4, the plunger 6 is slidably disposed at a left portion of the cavity 13, and the plunger 6 can abut against a right end wall of the left portion of the cavity 13 when sliding rightward in the direction of fig. 4, thereby blocking both left and right sides of the cavity 13 so that the washing water in the right portion cannot enter into the left portion. Further, the motor 5 is fixedly connected with the housing 1, an output shaft of the motor 5 is in driving connection with the left end of the plunger 6 through a cam or a hinge rod, and the motor 5 can drive the plunger 6 to slide along the axial direction when rotating, so that the plunger 6 can block the left part and the right part of the cavity 13, or the left part and the right part of the cavity 13 can be allowed to be communicated.

Since the means for driving the plunger 6 to slide back and forth in the axial direction by the motor 5 is well known to those skilled in the art, it will not be described herein in detail.

With continued reference to fig. 4, in order to prevent wash water in the left portion of the cavity 13 from overflowing the annular gap between the plunger 6 and the housing 1 (the position where the plunger 6 is slidably coupled to the housing 1 in fig. 4), the left end of the bellows 7 in fig. 4 is sealingly coupled to the left end wall of the left portion of the cavity 13, and the right end of the bellows 7 in fig. 4 is sealingly coupled to the right end of the plunger 6.

The operation principle and the cleaning operation of the drain pump of the present invention will be described in detail with reference to fig. 3 to 5.

When the washing machine needs to drain water, the motor 5 drives the plunger 6 to slide leftwards, and the left and right parts of the cavity 13 are communicated accordingly. The washing water in the water inlet passage 111 sequentially passes through the first U-shaped port 32 and the second U-shaped port 42 and then enters the gaps between the plurality of convex structures 31. After passing through the plurality of protrusion structures 31, the washing water flows from the right portion of the cavity 13 to the left portion of the cavity 13 in the axial direction of the filter member 3, and finally flows to the outside through the water outlet passage 121.

Wherein, when the washing water flows through the plurality of protrusion structures 31, the plurality of protrusion structures 31 intercept the thread scraps 8 in the washing water, thereby achieving the purpose of filtering the washing water.

When the washing machine finishes draining, the motor 5 drives the plunger 6 to slide rightwards, and the left part and the right part of the cavity 13 are accordingly separated.

When the drain valve needs to be cleaned, the user manually unscrews the cover body 2 out of the mounting hole, and thus takes the filter member 3 and the cleaning member 4 out of the housing 1. Then, the user separates the cleaning member 4 from the filter member 3 by operating the handle 43. With the separation of the cleaning member 4 from the filter member 3, the thread scraps 8 on the convex structure 31 are scraped off by the cleaning member 4. After the cleaning member 4 is separated from the filtering member 3, the user can clean the thread scraps 8 on the cleaning member 4 only by reversing the cleaning member 4.

Therefore, the drain valve can quickly and conveniently clean the thread scraps 8 in the drain valve through the arrangement of the cleaning piece 4, and is convenient for the operation of a user. And the invention also avoids the situation that the cleaning piece 4 falls into the cavity 13 when the filter member 3 is taken out by making the attaching direction of the cleaning piece 4 and the filter member 3 vertical to the direction of taking out the shell 1.

Furthermore, although not shown, in another possible embodiment of the invention, the end of the filter element 3 remote from the cover 2 may be provided in a closed configuration, i.e. an end cap may be provided on the end of the filter element 3 remote from the cover 2, as required by a person skilled in the art. A plurality of protrusion structures 31 are then provided on the end cap while a plurality of filtering holes for allowing the washing water to pass therethrough are provided on the end cap. Accordingly, the cleaning member 4 is provided in a structure matching the shape of the end cap so that the cleaning member 4 is attached to the inside of the end cap.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
