Description

Technical Field

[0001] This utility model relates to the field of washing machine equipment technology, specifically a washing machine drain pump with a water-stopping structure. Background Technology

[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. According to its drainage method, it can be divided into top-drain type and bottom-drain type. Among them, the drainage of top-drain washing machines is achieved by a drain pump. The drain pump is usually composed of a pump body, output source, water inlet, drain outlet and filter cartridge.

[0003] However, existing washing machine drain pumps cannot effectively stop water flow, causing water to continue flowing out of the washing machine even when the drain valve is not working, resulting in a waste of water resources. In addition, the filter cartridge inside the existing washing machine drain pump is not easy to disassemble and replace.

[0004] Therefore, a washing machine drain pump with a water-stopping structure is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a washing machine drain pump with a water-stopping structure to solve the problems mentioned in the background art, such as the inability of existing washing machine drain pumps to effectively stop water flow, which leads to water flowing continuously out of the washing machine even when the drain valve is not working, resulting in water waste, and the inconvenience of disassembling and replacing the filter cartridge inside the existing washing machine drain pump.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a washing machine drain pump with a water-stopping structure, comprising a pump body, drainage components connected to both sides of the pump body, a threaded block threadedly connected to the top of the pump body, a knob fixedly installed on the top of the threaded block, a snap-fit ​​component fixedly installed at the bottom of the threaded block, a filter component snap-fitted inside the snap-fit ​​component, a water-stopping component installed inside the drainage components, and an output component installed at the bottom of the pump body.

[0007] Preferably, the output component includes an output motor, which is fixedly installed at the center of the bottom of the pump body. An impeller is fixedly installed at the output end of the output motor. A mounting block is fixedly connected to one side of the output motor, and an electromagnet is fixedly installed on the top of the mounting block. The drainage pump achieves efficient drainage by rapidly rotating the impeller driven by the output motor.

[0008] Preferably, the drainage assembly includes a drain pipe and an inlet pipe, the drain pipe being fixedly connected to one side of the pump body, the inlet pipe being fixedly connected to the other side of the pump body, and one end of the drain pipe and one end of the inlet pipe extending into the interior of the pump body.

[0009] Preferably, the snap-fit ​​assembly includes a snap-fit ​​cylinder, which is fixedly installed at the bottom of the threaded block. The snap-fit ​​cylinder has a snap-fit ​​groove, and a first spring is fixedly installed inside the snap-fit ​​cylinder. A pressing plate is fixedly installed at the bottom of the first spring, and the pressing plate is slidably installed inside the snap-fit ​​cylinder. This ensures that the filter cylinder will not loosen or fall off due to vibration, water flow impact, or other reasons when the drainage pump is working, thus ensuring the reliability of the connection and maintaining the normal operation of the drainage pump.

[0010] Preferably, the filter assembly includes a filter cartridge, with a plug rod fixedly installed on the top of the filter cartridge, and a snap-fit ​​post fixedly installed on the outer side of the plug rod. The snap-fit ​​post is slidably installed inside the snap-fit ​​groove, and the plug rod is in contact with the extrusion plate. This allows for timely cleaning or replacement of the filter cartridge, effectively preventing impurities from accumulating and causing wear and blockage to the drainage pump, thereby extending the service life of the drainage pump and reducing maintenance and replacement costs.

[0011] Preferably, the water-stopping assembly includes a mounting shell and a sealing plate. The mounting shell is fixedly installed on the outside of the water inlet pipe, and the sealing plate is slidably installed inside the water inlet pipe. An armature is fixedly installed at the bottom of the sealing plate. Two second springs are symmetrically installed inside the mounting shell, and the tops of the two second springs are respectively fixedly installed on both sides of the sealing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] With the snap-fit ​​assembly and filter assembly, when installing the filter cartridge, simply align the filter cartridge with the position and use the elastic deformation of the spring to snap it into place. This makes it convenient for users to clean or replace the filter cartridge regularly without the need for complicated tools or professional skills, thus lowering the maintenance threshold and saving time and effort.

[0014] The water-stop component effectively prevents water from flowing back into the washing machine from the drain pipe, thus avoiding leaks, reducing water consumption, and helping to keep the inside of the washing machine clean and hygienic, preventing secondary pollution of clothes.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-4 This utility model provides a washing machine drain pump with a water-stopping structure, including a pump body 1, with drain components connected to both sides of the pump body 1, a threaded block 2 threadedly connected to the top of the pump body 1, a knob 3 fixedly installed on the top of the threaded block 2, a snap-fit ​​component fixedly installed at the bottom of the threaded block 2, a filter component snapped into the snap-fit ​​component, a water-stopping component installed inside the drain components, and an output component installed at the bottom of the pump body 1.

[0022] Furthermore, the output component includes an output motor 13, which is fixedly installed at the center of the bottom of the pump body 1. An impeller 14 is fixedly installed at the output end of the output motor 13. A mounting block 15 is fixedly connected to one side of the output motor 13, and an electromagnet 16 is fixedly installed on the top of the mounting block 15. When the washing machine needs to drain, the output motor 13 is energized. When current passes through the output motor 13, the output motor 13 drives the impeller 14 at the output end to rotate and drain the water.

[0023] Furthermore, the drainage assembly includes a drain pipe 11 and an inlet pipe 12. The drain pipe 11 is fixedly connected to one side of the pump body 1, and the inlet pipe 12 is fixedly connected to the other side of the pump body 1. One end of the drain pipe 11 and one end of the inlet pipe 12 both extend into the interior of the pump body 1. When the impeller 14 rotates, it generates a large amount of centrifugal force, thereby drawing water from the washing machine through the inlet pipe 12 into the interior of the pump body 1, and then discharging it through the drain pipe 11.

[0024] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​cylinder 4, which is fixedly installed at the bottom of the threaded block 2. A snap-fit ​​groove 5 is provided on the snap-fit ​​cylinder 4. A first spring 10 is fixedly installed inside the snap-fit ​​cylinder 4, and a pressing plate 9 is fixedly installed at the bottom of the first spring 10. The pressing plate 9 is slidably installed inside the snap-fit ​​cylinder 4. Further, the filter assembly includes a filter cylinder 6. A connecting rod 7 is fixedly installed at the top of the filter cylinder 6, and a snap-fit ​​post 8 is fixedly installed on the outside of the connecting rod 7. The snap-fit ​​post 8 is slidably installed inside the snap-fit ​​groove 5. The connecting rod 7 contacts and connects with the pressing plate 9. The filter cylinder 6 fits against the inner wall of the pump body 1. A filter screen is installed at the bottom of the filter cylinder 6. When draining, water flows through... The water inlet pipe 12 enters the pump body 1, where it passes through a filter screen to block waste, and then discharges it through the drain pipe 11. When installing the filter cylinder 6, the plug rod 7 is slidably inserted into the locking cylinder 4, and the locking post 8 is connected to the locking groove 5. Then, some force is applied to make the plug rod 7 press the extrusion plate 9, causing it to slide and squeeze the first spring 10. When the locking post 8 reaches a certain position, it rotates according to the shape of the locking groove 5, and the plug rod 7 drives the locking post 8 to move. Then, the pressing stops, and the first spring 10 releases its force to drive the extrusion plate 9 to squeeze the plug rod 7, so that the plug rod 7 and the locking groove 5 are locked together to complete the installation. When disassembling, press and rotate again to unlock.

[0025] Furthermore, the water-stopping assembly includes a mounting shell 17 and a sealing plate 18. The mounting shell 17 is fixedly installed on the outside of the water inlet pipe 12, and the sealing plate 18 is slidably installed inside the water inlet pipe 12. An armature 20 is fixedly installed at the bottom of the sealing plate 18. Two second springs 19 are symmetrically installed inside the mounting shell 17. The tops of the two second springs 19 are fixedly installed on both sides of the sealing plate 18. When the electromagnet 16 is energized and activated, it attracts the armature 20. The armature 20 drives the top sealing plate 18 to slide down, allowing water to flow through the water inlet pipe 12. When the sealing plate 18 slides down, it squeezes the two second springs 19, causing them to be under force. When there is no drainage, the electromagnet 16 is de-energized, and it will no longer attract the armature 20. The two second springs 19 release their force, causing the sealing plate 18 to reset and seal the water inlet pipe 12.

[0026] In this embodiment, the water inlet pipe 12 is connected to the washing machine, and the drain pipe 11 is connected to the drain outlet. When the washing machine needs to drain, the output motor 13 and the electromagnet 16 are energized. After the electromagnet 16 is energized, it attracts the armature 20. The armature 20 drives the top sealing plate 18 to slide down, allowing the water inlet pipe 12 to flow. When the sealing plate 18 slides down, it squeezes the two second springs 19, causing them to be under force. After the output motor 13 starts, it drives the impeller 14 at the output end to rotate. When the impeller 14 rotates, it generates a large amount of centrifugal force, thereby drawing water from the washing machine through the water inlet pipe 12 into the pump body 1. Large dirt is blocked by the filter cartridge 6 and then discharged through the drain pipe 11. When not draining, the energization of the output motor 13 and the electromagnet 16 is deactivated. 6. After the power is turned off, the armature 20 will no longer be attracted. The two second springs 19 release their force, causing the sealing plate 18 to reset and seal the water inlet pipe 12. After long-term use, the filter cartridge 6 may need to be replaced by disassembly and installation. When installing the filter cartridge 6, slide the plug rod 7 into the inside of the locking cylinder 4 and connect the locking post 8 with the locking groove 5. Then apply some force to make the plug rod 7 press the extrusion plate 9, so that it slides and squeezes the first spring 10. When the locking post 8 reaches a certain position, rotate the plug rod 7 according to the shape of the locking groove 5 to move the locking post 8. Then stop pressing. The first spring 10 releases its force to squeeze the extrusion plate 9 to squeeze the plug rod 7, so that the plug rod 7 and the locking groove 5 are locked together to complete the installation. When disassembling, press and rotate again to unlock.
