Description

Technical Field

[0001] The present invention relates to the field of washing machine motors, and in particular to a washing machine motor with high efficiency and mute function. Background Art

[0002] The washing machine motor is a core component responsible for driving the washing and spinning operations. After prolonged use, washing machine motors often experience abnormal noise, impacting the user experience. Motor noise primarily comes from three sources: air noise, mechanical noise, and electromagnetic noise. Internal circuit noise is sometimes also included as a source of noise.

[0003] As far as mechanical noise is concerned, a good bearing lubrication system is one of the key means to solve motor noise. Traditional motor bearing lubrication mainly adopts the following two methods: 1. Pre-filled sealed lubrication: A fixed amount of grease is filled into the bearing before leaving the factory. However, after long-term use, the grease is easily lost due to aging, volatilization or centrifugal force, resulting in increased dry friction, significantly increased noise, and inability to relubricate. 2. External active lubrication system: Lubricating oil is regularly injected through an electric pump or mechanical device. However, the structure is complex, the cost is high, and it is difficult to control the amount of oil injected. Excessive injection will increase oil resistance, forming a fluid damping effect, reducing motor speed and energy efficiency; insufficient oil injection cannot effectively reduce noise and accelerates bearing wear.

DETAILED DESCRIPTION

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0022] like Figures 1 to 6 A washing machine motor with high efficiency and quiet function is shown, comprising: The storage shell 2 is fixedly sleeved on the rotating shaft 103 of the motor body 1 and is used to store lubricating oil; The piston 3 is slidingly and sealingly connected in the storage shell 2; Flange 4, which is slidably engaged with the rotating shaft 103 of the motor body 1, and is slidably sleeved on the outer wall of the storage shell 2, with a return spring 5 fixedly connected between the flange 4 and the storage shell 2; Several connecting rods 6, the top ends of the several connecting rods 6 are fixedly connected to the bottom end of the flange 4, and the bottom ends pass through the top end of the storage shell 2 and are fixedly connected to the piston 3; An oil pipe assembly, one end of which is connected to the storage housing 2 and the other end of which is connected to the bearing sleeve 101 on the motor body 1; An air pressure balancer is provided on the bearing sleeve 101 and is used to balance the air pressure in the bearing sleeve 101; In the existing technology, lubricating oil is regularly injected through electric pumps or mechanical devices, which makes it difficult to control the amount of oil injected. Excessive injection will increase oil resistance, forming a fluid damping effect, reducing motor speed and energy efficiency. Insufficient oil injection will not effectively reduce noise and accelerate bearing wear. This technical solution can solve the above problems. The specific operation is as follows: After the clothes are placed in the drum of the washing machine, the flange 4 moves downward due to the pressure of the drum, and the return spring 5 is compressed. During the downward movement of the flange 4, the piston 3 moves downward under the connecting action of the connecting rod 6, thereby compressing the space in the storage shell 2, so that positive pressure is generated in the storage shell 2. Then, the lubricating oil in the storage shell 2 is transported to the bearing sleeve 101 through the oil pipe assembly, realizing self-lubrication between the rotating shaft 103 and the bearing sleeve 101, reducing the friction between the rotating shaft 103 and the bearing sleeve 101 when the motor is working, thereby reducing noise; Furthermore, the amount of lubricating oil injected into the bearing sleeve 101 is determined by the distance the flange 4 moves downward, which is determined by the gravity of the drum. Therefore, when too much clothing is placed in the drum, the gravity of the drum increases, the distance the flange 4 moves downward increases, and the amount of lubricating oil injected into the bearing sleeve 101 increases. This allows the amount of lubricating oil injected to be automatically adjusted according to the weight of the clothing, avoiding insufficient or excessive injection of lubricating oil, which would cause noise or reduce the motor speed. (When the amount of lubricating oil injected increases, the oil resistance will slightly reduce the rotation speed of the rotating shaft 103, similar to the fluid damping effect.) When the clothes are washed and taken out of the drum, the gravity in the drum decreases and returns to the initial value. Under the action of the reset spring 5, the flange 4 moves upward, thereby causing the storage shell 2 to reset. The lubricating oil in the bearing sleeve 101 is sucked away through the oil pipe assembly (the initial amount is retained to ensure basic lubrication). On the one hand, it prepares for automatic lubrication according to the amount of clothes next time. On the other hand, it prevents the lubricating oil in the sleeve from aging or loss, so that the lubricating oil can be recycled.

[0023] During implementation, the air pressure balancer includes a plurality of air grooves 102, which are arranged in an array in the bearing sleeve 101. The positions of the top of the bearing sleeve 101 corresponding to the air grooves 102 are fixedly connected to the air pressure balance pipe 7. The top of the air pressure balance pipe 7 is provided with an air hole 701. A movable plug 8 is slidingly sealed in the air pressure balance pipe 7. A pressure spring 9 is fixedly connected between the piston 3 and the air pressure balance pipe 7. Specifically, by providing a pneumatic balancer, when oil is injected, the air pressure in the bearing sleeve 101 increases. Under the action of the air pressure, the movable plug 8 moves upward, and the pressure spring 9 generates elastic force, thereby balancing the air pressure in the bearing sleeve 101 and ensuring that the lubricating oil can be injected into the bearing sleeve 101. When oil is sucked out, the pressure in the bearing sleeve 101 decreases, and under the action of the air pressure and the pressure spring 9, the lubricating oil in the bearing sleeve 101 can be sucked out. In addition, by providing the above-mentioned setting of the air pressure balancer, it is possible to ensure that the bearing sleeve 101 is in a closed environment, which is beneficial to prevent the lubricating oil in the sleeve from aging or loss.

[0024] It should be noted that the bearing sleeve 101 includes an outer static sleeve and an inner dynamic sleeve, the outer static sleeve and the inner dynamic sleeve are provided with balls, the air groove 102 is opened on the inner dynamic sleeve, and the first connecting tube 11 and the third connecting tube 15 are fixedly connected to the inner dynamic bearing sleeve 101.

[0025] As a further embodiment of the present invention, the oil pipe assembly includes: The inner shell 10 is fixedly connected to the storage shell 2. A through hole 1001 is opened at the top of the inner shell 10 for communicating with the space inside the storage shell 2. The inner shell 10 is provided with an oil discharge cavity 1002 and an oil suction cavity 1003; An oil delivery pipe assembly, one end of which is connected to the oil drain chamber 1002 and the other end of which is connected to the bearing sleeve 101 on the motor body 1, for discharging the lubricating oil in the oil drain chamber 1002 into the bearing sleeve 101; An oil suction pipe assembly, one end of which is connected to the oil suction chamber 1003 and the other end of which is connected to the bearing sleeve 101 on the motor body 1, for sucking the lubricating oil in the bearing sleeve 101 into the oil suction chamber 1003; Specifically, by setting up an oil delivery pipe group and an oil suction pipe group, when the flange 4 moves downward, the lubricating oil in the oil discharge chamber 1002 is discharged into the bearing sleeve 101 through the oil delivery pipe group. When the flange 4 moves upward, the lubricating oil in the bearing sleeve 101 is sucked into the oil suction chamber 1003 through the oil suction pipe group. The oil discharge and oil suction are separated by two independent oil pipe assemblies to avoid cross contamination.

[0026] As a further embodiment of the present invention, the oil pipeline group includes: A first connecting pipe 11, the bottom end of which is fixedly connected to the bearing sleeve 101, and a first one-way valve 12 is provided in the first connecting pipe 11; A second connecting pipe 13, the top end of which is fixedly connected to the oil drain chamber 1002, and the bottom end of which is rotatably connected to the first sealing valve 14, which is threadedly connected to the first connecting pipe 11; The oil suction pipe set includes: A third connecting pipe 15, the bottom end of which is fixedly connected to the bearing sleeve 101, and a second one-way valve 16 is provided in the third connecting pipe 15; The fourth connecting pipe 17 has a top end fixedly connected to the oil suction chamber 1003 , and a bottom end of the fourth connecting pipe 17 is rotatably connected to the second sealing valve 18 , which is threadedly connected to the third connecting pipe 15 ; Specifically, by providing the first one-way valve 12 and the second one-way valve 16, when the flange 4 moves downward, the first one-way valve 12 is opened and the second one-way valve 16 is closed, so that the lubricating oil in the oil discharge chamber 1002 is discharged into the bearing sleeve 101 through the first one-way valve 12. When the flange 4 moves upward, the first one-way valve 12 is sealed and the second one-way valve 16 is opened, so that the lubricating oil in the bearing sleeve 101 enters the oil suction chamber 1003 through the second one-way valve 16. In addition, by providing the first sealing valve 14 and the second sealing valve 18 , disassembly and assembly of the oil pipe assembly between the storage housing 2 and the bearing sleeve 101 are facilitated.

[0027] Furthermore, O-rings are provided in both the first sealing valve 14 and the second sealing valve 18 to ensure the sealing of the oil pipe assembly under vibration conditions and avoid oil leakage.

[0028] As a further embodiment of the present invention, the present invention further includes two filter plates 19, which are symmetrically fixedly connected to the inner wall of the inner shell 10 and are used to separate the inner shell 10 into an oil discharge chamber 1002 and an oil suction chamber 1003; Specifically, by setting up the filter plate 19, when the flange 4 moves upward and the lubricating oil in the bearing sleeve 101 is sucked into the oil suction chamber 1003, the lubricating oil is filtered by the filter plate 19 to remove impurities in the lubricating oil, and the impurities are retained in the oil suction chamber 1003, while the clean lubricating oil enters the oil discharge chamber 1002 through the filter plate 19, thereby ensuring that there are no impurities in the injected lubricating oil, and avoiding the impurities in the lubricating oil affecting the lubrication effect in the bearing sleeve 101.

[0029] As a further embodiment of the present invention, the present invention further includes two scrapers 20, which are vertically slidably connected to the inner wall of the inner shell 10 corresponding to the position of the filter plate 19. A pushing component is provided inside the inner shell 10, and the pushing component is coordinated with the rotation of the rotating shaft to push the two scrapers 20 downward to dredge the filter plate 19; The pushing assembly includes two driving plates 21, which are respectively fixedly connected to the side walls of the scraper 20. A driving inclined groove 2101 is opened on the side of the driving plate 21. Two sliding rods 22 are symmetrically fixedly connected to the inside of the inner shell 10. The surface of the sliding rod 22 is slidably connected to the driving frame 23. The surface of the sliding rod 22 is provided with a compression spring 24. The two ends of the compression spring 24 are respectively fixedly connected to the driving frame 23 and the inner wall of the inner shell 10. The end of the driving frame 23 is fixedly connected to a connecting pin, which is slidably connected to the driving inclined groove 2101. Specifically, during the rotation of the motor shaft 103, the storage shell 2 drives the inner shell 10 to rotate. Under the action of centrifugal force, the drive frame 23 moves along the surface of the slide rod 22, so that the connecting pin moves along the drive inclined groove 2101. Driven by the drive inclined groove 2101, the scraper 20 moves downward, thereby scraping off impurities on the filter plate 19 to clear the filter plate 19 and avoid blockage.

[0030] Furthermore, a permanent magnet 25 is provided on the side wall of the bottom end of the filter plate 19 to absorb metal debris generated by the wear of the bearing sleeve 101.

[0031] The working principle of the present invention is as follows: After the clothes are placed in the drum of the washing machine, the flange 4 moves downward due to the pressure of the drum, and the return spring 5 is compressed. During the downward movement of the flange 4, the piston 3 moves downward under the connecting action of the connecting rod 6, thereby compressing the space in the storage shell 2, so that positive pressure is generated in the storage shell 2. Then, the lubricating oil in the storage shell 2 is transported to the bearing sleeve 101 through the oil pipe assembly, realizing self-lubrication between the rotating shaft 103 and the bearing sleeve 101, reducing the friction between the rotating shaft 103 and the bearing sleeve 101 when the motor is working, thereby reducing noise; Furthermore, the amount of lubricating oil injected into the bearing sleeve 101 is determined by the distance the flange 4 moves downward, which is determined by the gravity of the drum. Therefore, when too much clothing is placed in the drum, the gravity of the drum increases, the distance the flange 4 moves downward increases, and the amount of lubricating oil injected into the bearing sleeve 101 increases. This allows the amount of lubricating oil injected to be automatically adjusted according to the weight of the clothing, avoiding insufficient or excessive injection of lubricating oil, which would cause noise or reduce the motor speed. (When the amount of lubricating oil injected increases, the oil resistance will slightly reduce the rotation speed of the rotating shaft 103, similar to the fluid damping effect.) When the clothes are washed and taken out of the drum, the gravity in the drum decreases and returns to the initial value. Under the action of the reset spring 5, the flange 4 moves upward, thereby causing the storage shell 2 to reset. The lubricating oil in the bearing sleeve 101 is sucked away through the oil pipe assembly (the initial amount is retained to ensure basic lubrication). On the one hand, it prepares for automatic lubrication according to the amount of clothes next time. On the other hand, it prevents the lubricating oil in the sleeve from aging or loss, so that the lubricating oil can be recycled.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
