Description

A washing machine drain pump inlet assembly with self-cleaning function Technical Field

[0001] This utility model relates to the field of washing machine technology, specifically to a washing machine drain pump water inlet assembly with a self-cleaning function. Background Technology

[0002] The washing machine drain pump is a key component for achieving the drainage function of a washing machine. The washing machine drain pump mainly uses a motor to drive the impeller to rotate, generating centrifugal force in the pump body, thereby throwing out the sewage in the washing machine and discharging it through the drain pipe.

[0003] The drain pump inlet assembly drains wastewater from inside the washing machine. During the washing process, a large amount of fibers, paper scraps, and various small debris left in the pockets of clothes will enter the drain pump inlet assembly along with the wash water. As the usage time increases, these impurities will gradually accumulate in key parts of the inlet assembly, such as the inlet and filter screen. The accumulation of impurities will first cause the water flow channel to narrow, and the water flow will be significantly reduced, resulting in a significant decrease in drainage efficiency. The drain pump will then need to withstand a greater load to overcome the water flow resistance. Under this high load condition for a long time, the drain pump motor is prone to damage due to overload, resulting in failure to drain normally, which will affect the use of the machine. Summary of the Invention

[0004] The purpose of this invention is to provide a washing machine drain pump inlet assembly with a self-cleaning function to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a water inlet assembly for a washing machine drain pump with self-cleaning function, comprising a drain pump body; an inlet pipe is installed at the input end of the drain pump body, and a filter ring is rotatably installed at the end of the inlet pipe away from the drain pump body; a transmission groove is provided on the outer surface of the filter ring, and a transmission disc is installed inside the transmission groove on the outer surface of the drain pump body and the filter ring; a connecting pipe is rotatably installed at the end of the filter ring away from the inlet pipe, and a scraper is provided on the inner wall of the connecting pipe near the end of the filter ring.

[0006] Preferably, a discharge valve is installed at the bottom of the connecting pipe, and a processing mechanism is installed at the bottom of the discharge valve.

[0007] Preferably, the processing mechanism includes a processing seat disposed at the bottom of the discharge valve, two sets of crushing rollers are rotatably mounted inside the processing seat, a transmission gear plate is mounted on the outer side of one end of the crushing rollers, a motor is fixedly mounted on one side of the outer wall of the processing seat, and the output end of the motor is connected to a set of crushing rollers.

[0008] Preferably, a valve is installed at the bottom of the processing seat.

[0009] Preferably, a fixing frame is installed on the outer side of the transmission disk, with the bottom of one side of the fixing frame connected to the outer wall of the water inlet pipe and the bottom of the other side of the fixing frame connected to the outer wall of the connecting pipe.

[0010] Preferably, both the inlet pipe and the connecting pipe are equipped with flow meters.

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

[0012] 1. This utility model utilizes a filter ring, transmission groove, transmission disc, and scraper in conjunction. The filter ring intercepts impurities such as hair, fibers, and paper scraps in wastewater, preventing these impurities from directly entering the main body of the drainage pump through the inlet pipe and thus preventing damage to the drainage pump due to blockage. When the transmission disc rotates, it drives the filter ring to rotate between the inlet pipe and the connecting pipe. At this time, the scraper can scrape off the impurities intercepted on the filter ring, preventing excessive accumulation of impurities on the filter ring that affects filtration and water flow. This improves the cleaning ability of the drainage pump's inlet assembly, ensures unobstructed drainage channels, improves drainage efficiency, and does not affect subsequent use by personnel.

[0013] 2. This utility model uses a discharge valve and a processing mechanism in conjunction. By opening the discharge valve, impurities can be discharged into the processing seat. Then, a motor drives one set of crushing rollers to rotate, and a transmission gear disc drives another set of transmission gear discs to rotate, thereby driving another set of crushing rollers to rotate. Through the rotation of the two sets of crushing rollers, impurities such as hair, fibers, and paper scraps can be crushed. The crushed impurities are smaller in size and easier to be discharged with the water flow, reducing the risk of pipe blockage and ensuring the smooth flow of the drainage system.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;

[0021] Example:

[0022] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to Figures 1 to 4. The water inlet assembly of a washing machine drain pump with self-cleaning function provided in this application includes a drain pump body 1. A water inlet pipe 101 is installed at the input end of the drain pump body 1. A filter ring 2 is rotatably installed at the end of the water inlet pipe 101 away from the drain pump body 1. A transmission groove 201 is provided on the outer surface of the filter ring 2. A transmission disk 202 is installed inside the transmission groove 201 on the outer surface of the drain pump body 1 and the filter ring 2. The transmission disk 202 is composed of a motor and a gear disk. A connecting pipe 3 is rotatably installed at the end of the filter ring 2 away from the water inlet pipe 101. A scraper 301 is provided on the inner wall of the connecting pipe 3 near the filter ring 2.

[0023] Specifically, the filter ring 2 can intercept impurities such as hair, fibers, and paper scraps in the sewage, preventing these impurities from directly entering the drainage pump body 1 through the inlet pipe 101. This prevents the drainage pump body 1 from being damaged due to blockage by impurities and ensures the normal operation of the drainage pump body 1. The transmission groove 201 on the outer surface of the filter ring 2 cooperates with the transmission disc 202 to form a transmission structure. When the transmission disc 202 rotates, it can drive the filter ring 2 to rotate between the inlet pipe 101 and the connecting pipe 3. At this time, the scraper 301 can contact the surface of the filter ring 2 as the filter ring 2 rotates. The scraper 301 can scrape off the impurities intercepted on the filter ring 2, preventing impurities from accumulating too much on the filter ring 2 and affecting filtration and water flow. This further improves the cleaning ability of the drainage pump inlet assembly for impurities, ensures unobstructed drainage channels, and improves drainage efficiency.

[0024] Please refer to Figures 1 and 2. A discharge valve 4 is installed at the bottom of the connecting pipe 3, and a processing mechanism 5 is installed at the bottom of the discharge valve 4.

[0025] Please refer to Figures 2 and 4 for details. The processing mechanism 5 includes a processing seat 504 located at the bottom of the discharge valve 4. Two sets of crushing rollers 503 are rotatably mounted inside the processing seat 504. A transmission gear plate 502 is mounted on the outer side of one end of the crushing roller 503. A motor 501 is fixedly mounted on one side of the outer wall of the processing seat 504. The output end of the motor 501 is connected to a set of crushing rollers 503.

[0026] Please refer to Figure 2 for details. A valve 6 is installed at the bottom of the treatment unit 504.

[0027] Specifically, in order to process the separated impurities, the discharge valve 4 is opened to discharge the impurities into the treatment seat 504, preventing excessive accumulation of impurities in the connecting pipe 3 and affecting drainage. When the impurities enter the treatment seat 504 from the discharge valve 4, the motor 501 drives a set of crushing rollers 503 to rotate, and the transmission gear 502 drives another set of transmission gear 502 to rotate, thereby driving another set of crushing rollers 503 to rotate. By driving the two sets of crushing rollers 503 to rotate simultaneously, the crushing rollers 503 can crush impurities such as hair, fibers, and paper scraps. The crushed impurities are smaller in size and easier to be discharged with the water flow, reducing the risk of pipe blockage and ensuring the smooth flow of the drainage system. Finally, the crushed material can be discharged by opening the valve 6.

[0028] Please refer to Figure 1. A fixing frame 203 is installed on the outside of the transmission disk 202. The bottom of one side of the fixing frame 203 is connected to the outer wall of the water inlet pipe 101, and the bottom of the other side of the fixing frame 203 is connected to the outer wall of the connecting pipe 3.

[0029] Specifically, in order to fix the transmission disc 202 and provide auxiliary support, the fixing frame 203 is connected to the outer wall of the water inlet pipe 101 and the connecting pipe 3 respectively, connecting the two components together to keep their relative positions fixed. The fixing frame 203 is located outside the transmission disc 202 and provides support for the transmission disc 202, keeping it in a specific position and ensuring that the transmission disc 202 can stably cooperate with the transmission groove 201 of the filter ring 2 to realize the transmission function.

[0030] Please refer to Figures 1 and 2. Flow meters 7 are installed inside both the inlet pipe 101 and the connecting pipe 3. The flow meter 7 is a turbine flow meter, which uses an impeller placed in the fluid to sense the average velocity of the fluid and thus deduce the flow rate.

[0031] Specifically, in order to monitor the water flow inside the inlet pipe 101 and the connecting pipe 3, the flow meter 7 monitors the water flow rate inside the inlet pipe 101 and the connecting pipe 3. This allows us to understand the drainage speed and volume of the inlet pipe 101 and the connecting pipe 3. If the flow rate is abnormal, it indicates that the filter ring 2 is clogged.

[0032] Working principle: When the wastewater from the washing machine passes through the inlet pipe 101 and the connecting pipe 3, the flow meter 7 can monitor the water flow rate inside the inlet pipe 101 and the connecting pipe 3. When there is a large difference between the two sets of flow data, it indicates that the filter ring 2 is blocked. At this time, the transmission disc 202 works and meshes with the transmission groove 201 to drive the filter ring 2 to rotate. The scraper 301 can scrape off the impurities intercepted on the filter ring 2. At the same time, the discharge valve 4 is opened, and the impurities can be discharged into the treatment seat 504. When the impurities enter the treatment seat 504 from the discharge valve 4, the motor 501 drives a set of crushing rollers 503 to rotate. The transmission gear disc 502 drives another set of transmission gear discs 502 to rotate, thereby driving another set of crushing rollers 503 to rotate. By driving the two sets of crushing rollers 503 to rotate at the same time, the crushing rollers 503 can crush impurities such as hair, fibers, and paper scraps. The crushed impurities are smaller in size and easier to be discharged with the water flow. Finally, the crushed material can be discharged by opening the valve 6.

[0033] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
