Description

Technical Field

[0001] This utility model relates to the technical field of washing machine drain pump filter components, and in particular to a washing machine drain pump component with a multi-stage impurity filtration structure. Background Technology

[0002] When a drum washing machine finishes washing clothes, the wastewater needs to be discharged into the sewer through a drain pump. To prevent impurities in the wastewater from clogging the washing machine's drain pipe, the wastewater needs to be filtered and cleaned through a filtration structure before being discharged into the sewer. However, existing washing machine drain pump filtration components often experience clogging problems when filtering larger debris in the wastewater.

[0003] For example, Chinese utility model patent CN217758011U discloses a washing machine drain pump assembly. Although this solution can quickly discharge small impurities from the outside of the washing machine through the drain pump filter screen and prevent small debris from accumulating and clogging the drain pump for a long time, when there are larger solid insoluble objects such as hairpins and screws in the washing wastewater, they are easy to get stuck in the filter screen or drain pipe. If fibrous impurities are added later, it will cause more serious blockage. Based on this, a washing machine drain pump assembly with a multi-stage impurity filtration structure is proposed to solve the above problems. Utility Model Content

[0004] To address the technical problem that washing machine drain pump assemblies cannot filter large debris, this utility model provides a washing machine drain pump assembly with a multi-stage debris filtering structure.

[0005] This utility model is achieved using the following technical solution: a washing machine drain pump assembly with a multi-stage filtration structure, including a drum body, a filter screen cylinder arranged inside the drum body, an auger blade arranged inside the filter screen cylinder, a water collection tank connected to the lower side of the drum body, a drain pump mechanism for injecting washing machine wastewater into the filter screen cylinder arranged on one side of the drum body, a centrifugal push plate mechanism for discharging solid insoluble matter from the filter screen cylinder arranged on the other side of the drum body, and a drainage hose mechanism arranged on one side of the water collection tank.

[0006] As a further improvement to the above solution, the auger blade is provided with multiple perforations.

[0007] As a further improvement to the above solution, the drainage pump mechanism includes a connecting pipe that is connected to one end of the filter screen cylinder, the connecting pipe extending outward through the cylinder body, and one end of the connecting pipe being connected to a drainage pump.

[0008] As a further improvement to the above solution, the centrifugal pusher mechanism includes a centrifugal baffle communicating with one side of the cylinder. A drive shaft is rotatably connected to the inner side of the centrifugal baffle, and multiple push plates are fixedly connected to the side of the drive shaft. The multiple push plates are arranged in a circumferential array. An annular groove is provided on the inner side of the centrifugal baffle. One end of each push plate is slidably connected to the inner side of the annular groove. One end of the drive shaft is fixedly connected to one end of the auger blade. A drive shaft drive mechanism for rotating the drive shaft is provided on the outer side of the centrifugal baffle.

[0009] As a further improvement to the above solution, the drive shaft mechanism includes a motor mounted on the outside of the centrifugal baffle, and the output end of the motor is fixedly connected to one end of the drive shaft.

[0010] As a further improvement to the above solution, the drainage hose mechanism includes a corrugated hose that communicates with one side of the water collection tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example:

[0022] Please refer to the diagram. Figure 3 This embodiment of a washing machine drain pump assembly with a multi-stage filtration structure includes a drum 2; a filter screen 9 is provided on the inner side of the drum 2. The filter screen 9 has a large mesh size. It should be noted that in this embodiment, it is placed horizontally. In other embodiments, the filter screen 9 can be installed at a certain angle on the inner side of the drum 2.

[0023] Please combine Figure 3 As shown, the filter cylinder 9 is equipped with an auger blade 7 inside, and the lower side of the cylinder 2 is connected to a water collection tank 10, which can collect the filtered sewage from below.

[0024] A drain pump mechanism is provided on one side of the drum 2 to inject wastewater from the washing machine into the filter screen 9, and a centrifugal push plate mechanism is provided on the other side of the drum 2 to discharge solid insoluble matter from the filter screen 9. A drainage hose mechanism is provided on one side of the water collection tank 10.

[0025] Please combine Figure 3 As shown, the screw conveyor blade 7 has multiple perforations 8. By setting the perforations 8, the screw conveyor blade 7 can reduce the ability to lift water flow, but it does not affect the ability to move and push large solid insoluble matter, and can ensure that sewage falls fully into the water collection tank 10.

[0026] Please combine Figure 1 As shown, the drain pump mechanism includes a connecting pipe that is connected to one end of the filter screen cylinder 9. The connecting pipe passes outward through the cylinder 2, and one end of the connecting pipe is connected to the drain pump 1. The drain pump 1 is installed inside the washing machine.

[0027] Please combine Figure 3 As shown, the centrifugal pusher mechanism includes a centrifugal baffle 5 that is connected to one side of the cylinder 2, and a baffle is provided on one side of the centrifugal baffle 5.

[0028] Please combine Figure 3 As shown, a drive shaft is rotatably connected to the inner side of the centrifugal baffle 5, and three push plates 6 are fixedly connected to the side of the drive shaft. The push plates 6 are arranged in a circumferential array, and multiple slots can be opened on the surface of each push plate 6.

[0029] Please combine Figure 4As shown, an annular groove is provided on the inner side of the centrifugal baffle 5. The diameter of the annular groove is larger than the diameter of the filter screen cylinder 9. At this time, when the auger blade 7 can push the solid insoluble matter to one end, the solid insoluble matter can fall into the annular groove.

[0030] Please combine Figure 4 As shown, one end of each push plate 6 is slidably connected to the inner side of the annular groove, one end of the drive shaft is fixedly connected to one end of the auger blade 7, and a drive shaft drive mechanism for rotating the drive shaft is provided on the outer side of the centrifugal baffle 5.

[0031] Please combine Figure 1 As shown, the drive shaft mechanism includes a motor 4 installed on the outside of the centrifugal baffle 5. The output end of the motor 4 is fixedly connected to one end of the drive shaft. By rotating the motor 4, not only can the push plate 6 be rotated to achieve the effect of throwing out solid insoluble matter, but the screw conveyor blade 7 can also be rotated to drive the solid insoluble matter to migrate.

[0032] Please combine Figure 1 As shown, the drainage hose mechanism includes a corrugated hose 3 connected to one side of the water collection tank 10. The corrugated hose 3 has limited extensibility, which facilitates connection with the drainage channel.

[0033] The implementation principle of a multi-stage filtration structure washing machine drain pump assembly in this application embodiment is as follows: When the wastewater after washing is injected into the filter cylinder 9 from one end of the drum 2 by the drain pump 1, when the motor 4 starts and drives the auger blade 7 to rotate, the wastewater flows down along the filter cylinder 9 into the water collection tank 10, while the fibers and fixed insoluble matter in the wastewater are filtered and retained in the filter cylinder 9. At this time, the rotating auger blade 7 can push the fixed insoluble matter along the inner side of the filter cylinder 9 to the other end until it is pushed into the annular groove inside the centrifugal baffle 5. At this time, the rotating push plate 6 can centrifugally throw the fixed insoluble matter along the inner wall of the centrifugal baffle 5.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
