Description

Technical Field

[0001] This invention belongs to the field of clothing cleaning technology, and particularly relates to a pulsator washing machine. Background Technology

[0002] Current top-loading washing machines consist of an inner tub and a pulsator. Most top-loading washing machines improve cleaning by having the pulsator and inner tub rotate in opposite directions. However, this rotation method has the following drawbacks: a) The inner tub, filled with washing water, is very heavy, resulting in a large torque on the motor, which can cause the motor to overheat and become damaged over time; b) Because the inner tub and pulsator need to constantly change direction during washing, the clutch generates significant reversing noise, affecting the user's sensory experience. Summary of the Invention

[0003] The embodiments of the present invention provide a pulsator washing machine, the main purpose of which is to provide a pulsator washing machine having two pulsators rotating in opposite directions.

[0004] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0005] An embodiment of the present invention provides a pulsator washing machine, comprising: a casing; an inner and outer tub assembly disposed inside the casing, comprising an inner tub and an outer tub, the inner tub rotating relative to the outer tub, the inner wall of the inner tub being provided with a biomimetic washboard for washing clothes; a first pulsator and a second pulsator, the first pulsator being disposed on the inner tub, the second pulsator being disposed on the first pulsator, the first pulsator and the second pulsator rotating relative to the outer tub, the first pulsator and the second pulsator having the same axis as the inner tub; a shaft mechanism disposed at the lower end of the inner and outer tub assembly, connected to the inner tub, the first pulsator and the second pulsator, for transmitting driving force to the inner tub, the first pulsator and the second pulsator; a gear train mechanism and a clutch mechanism connected to the shaft mechanism, the clutch mechanism being used to control the gear train mechanism to change the direction of the driving force, the gear train mechanism being used to transmit the changed driving force to the shaft mechanism; and a motor disposed at the lower end of the casing and connected to the clutch mechanism, providing driving force to the shaft mechanism.

[0006] In an embodiment of the present invention, by setting a first pulsator and a second pulsator, the two pulsators rotate simultaneously in opposite directions during washing, which effectively reduces the load on the motor. Compared with the huge load that the inner drum of a traditional pulsator washing machine bears when rotating, this embodiment can achieve the same cleaning effect by rotating the first pulsator and the second pulsator, thereby improving the service life of the washing machine and reducing the noise generated by the washing machine when washing clothes.

[0007] In some embodiments of the present invention, a first stirring rib is provided on the first impeller and a second stirring rib is provided on the second impeller. By providing the first stirring rib and the second stirring rib, the contact degree between the clothes and water is increased when the two impellers rotate, thereby improving the cleaning effect of the clothes.

[0013] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0014] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0015] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0016] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0017] refer to Figure 1 and Figure 3 An embodiment of the present invention provides a pulsator washing machine, including a housing 1 and an inner and outer tub assembly 11 disposed inside the housing 1. A first pulsator 13 and a second pulsator 14 are disposed inside the inner and outer tub assembly 11. The inner and outer tub assembly 11 consists of an inner tub 111 and an outer tub 112. The outer tub 112 is fixed to the housing 1, and the inner tub 111 is disposed inside the outer tub 112 and can rotate relative to the outer tub 112. The first pulsator 13 and the second pulsator 14 are located inside the inner tub 111 and are the same as the inner tub 111, both of which can rotate relative to the outer tub 112.

[0018] The first impeller 13 is much larger than the second impeller 14. Therefore, the first impeller 13 and the second impeller 14 form a nested structure, with the second impeller 14 surrounded by the first impeller 13 in the center. Thus, the first impeller 13 and the second impeller 14 can rotate independently of each other, preventing interference and contact between them during rotation, which would affect the cleaning effect of the washing machine, reduce the noise generated by the washing machine during operation, and improve the user experience when using the washing machine.

[0019] To improve the cleaning effect of the pulsator washing machine, this embodiment provides a biomimetic washboard 1111 on the inner wall of the inner tub 111. The biomimetic washboard 1111 is arranged in a circumferential pattern on the inner wall of the inner tub 111. The biomimetic washboard 1111 has vertical striped protrusions, which can simulate the protrusions on a traditional washboard. Setting the striped protrusions vertically can increase the friction between the clothes 8 and the biomimetic washboard 1111 during the washing process. Since the rotation center of the pulsator washing machine is usually aligned with the height direction of the cabinet 1, the stripes of the biomimetic washboard 1111 are aligned with the height direction of the cabinet 1, which can cause multiple frictions between the clothes 8 and the biomimetic washboard 1111. When the first pulsator 13 and the second pulsator 14 rotate in the inner tub 111, the water flow will generate high-speed centrifugal force, which will throw the clothes 8 onto the biomimetic washboard 1111, thereby maximizing the cleaning effect of the clothes 8.

[0020] Furthermore, in this embodiment, the first impeller 13 and the second impeller 14 rotate in opposite directions, effectively solving the problem of low cleaning efficiency in traditional impeller washing machines. Traditional impeller washing machines only have one impeller at the bottom. When cleaning clothes, one impeller cannot provide enough friction to clean the clothes at the bottom of the inner tub. In this embodiment, the first impeller 13 and the second impeller 14 are set up and rotate in opposite directions, which can simulate the effect of human hand washing clothes. The first impeller 13 and the second impeller 14 generate two rotational forces in opposite directions, so that the clothes 8 at the bottom of the inner tub 111 can also get a good cleaning effect.

[0021] During washing, the inner tub 111 does not need to rotate with the first impeller 13 and the second impeller 14. Since the inner tub is filled with water during washing, the motor needs to bear a huge load when driving the water-filled inner tub, and it needs to frequently change the rotation direction of the inner tub, which can easily cause damage to the internal motor shaft of the washing machine, seriously reducing the life of the washing machine. In addition, the washing machine will generate a lot of noise during operation, which seriously reduces the user experience. However, the impeller washing machine provided in this embodiment does not need to rotate the inner tub 111 during washing. It only relies on the rotation of the first impeller 13 and the second impeller 14 to drive the water flow in the inner tub 111. During spin-drying, the inner tub 111, the first impeller 13 and the second impeller 14 rotate together and in the same direction, which improves the spin-drying efficiency, reduces the noise generated by the washing machine during operation, and improves the user experience of using the washing machine.

[0022] To improve the contact between the clothes 8 and water in the inner tub 111, a first agitator rib 131 is provided on the first impeller 13, and a second agitator rib 141 is provided on the second impeller 14. Normally, the clothes 8 are placed into the inner tub 111 of the washing machine through the door cover 12 located at the top of the cabinet 1. Since the door cover 12 of the washing machine is usually round, the clothes 8 are usually curled up when the user puts them in. When the clothes 8 are curled up and rotate in the inner tub 111, it is difficult for the clothes 8 to fully contact the water flow, and the inside of the clothes 8 cannot be unfolded, which reduces the cleaning effect. However, by providing agitator ribs on the first impeller 13 and the second impeller 14, the curled-up clothes 8 can be unfolded when rotating, so that the clothes 8 can fully contact the water flow, increase the contact area between the clothes 8 and the bionic washboard 1111, and improve the cleaning effect of the clothes 8.

[0023] In an embodiment of the present invention, reference is made to... Figure 2 (Other components of the washing machine are omitted for clarity of the description of shaft mechanism 3, gear system mechanism and clutch mechanism 4) A shaft mechanism 3, gear system mechanism and clutch mechanism 4 are proposed. The gear system mechanism and clutch mechanism 4 need to transmit the driving force of motor 7 to inner tub 111, first impeller 13 and second impeller 14 through shaft mechanism 3 to drive inner tub 111, first impeller 13 and second impeller 14 to rotate. Shaft mechanism 3, gear system mechanism and clutch mechanism 4 are set at the lower end of inner and outer tub assembly 11 through clutch fixing bracket 2.

[0024] Furthermore, the shaft mechanism 3 consists of a first impeller shaft 31, a second impeller shaft 32, and an inner tub shaft 33. The first impeller shaft 31, the second impeller shaft 32, and the inner tub shaft 33 share the same axis and are designed as a single unit. The inner tub shaft 33 is nested outside the first impeller shaft 31 and rotates around the first impeller shaft 31. The first impeller shaft 31 is nested outside the second impeller shaft 32 and rotates around the second impeller shaft 32. This design minimizes the size of the washing machine, improves space utilization, and reduces the space occupied by the user's living space.

[0025] Because the inner tub 111 is relatively large, the inner tub shaft 33 is shorter in length than the first impeller shaft 31 and the second impeller shaft 32. The inner tub shaft 33 is fixedly connected to the bottom of the inner tub 111. The first impeller 13 is located inside the inner tub 111. Therefore, the length of the first impeller shaft 31 is greater than the length of the inner tub shaft 33 so that the first impeller shaft 31 passes through the inner tub 111 and is fixedly connected to the first impeller 13. The second impeller shaft 32 is located at the center of the inner tub shaft 33 and the first impeller shaft 31, and its length is greater than that of the first impeller shaft 31 so that the second impeller shaft 32 passes through the first impeller 13 and is fixedly connected to the second impeller 14. This three-axis overlapping design can reduce the space occupied by the washing machine shaft structure 3 and can provide driving force for the first impeller 13, the second impeller 14 and the inner tub 111 respectively, reducing the noise generated by the washing machine during operation.

[0026] Typically, a gear train mechanism and a clutch mechanism 4 are also required to connect the motor 7 and the shaft mechanism 3 to provide driving force to the shaft mechanism 3 and change the direction of the driving force. Therefore, the embodiments of the present invention provide a gear train mechanism and a clutch mechanism 4.

[0027] The gear train mechanism and the clutch mechanism 4 are arranged between the motor 7 and the shaft mechanism 3. The gear train mechanism is used to change the direction of the force, and the clutch mechanism 4 is used to control the gear meshing relationship of the gear train mechanism. When the motor 7 transmits the driving force from the clutch mechanism 4 to the gear train mechanism, the driving force is reversed in the gear train mechanism. After passing through the gear train mechanism, the driving force of the motor 7 is transmitted to the inner barrel shaft 33, the first impeller shaft 31 and the second impeller shaft 32 respectively to drive the first impeller 13, the second impeller 14 and the inner barrel 111 to rotate.

[0028] The gear system consists of an internal gear ring 41, intermediate gears 42, and a central gear 43. The inner ring of the internal gear ring 41 is fixedly connected to the second impeller shaft 32 via a first spline 411, so that the internal gear ring 41 and the second impeller shaft 32 rotate simultaneously and in the same direction. Multiple intermediate gears 42 are arranged around the inner gear ring 41. In this embodiment, there are three intermediate gears 42. The three intermediate gears 42 rotate around the internal gear ring 41 and are externally meshed with the internal gear ring 41. Therefore, the rotation direction of the intermediate gears 42 is opposite to the rotation direction of the internal gear ring 41. A central gear 43 is arranged outside the intermediate gears 42. The inner rings of the lower ends of the intermediate gears 42 and the central gear 43 are internally meshed. The inner ring of the upper end of the central gear 43 is fixedly connected to the first impeller shaft 31 via a third spline 431, so that the rotation direction of the first impeller shaft 31 is the same as the rotation direction of the central gear 43.

[0029] The internal gear ring 41, three intermediate gears 42 and the central gear 43 form a planetary gear system. The internal gear ring 41 and the central gear 43 are sun gears, and the intermediate gears 42 are planet gears that rotate between the internal gear ring 41 and the central gear 43. The planetary gear system has a stable transmission ratio and can reliably transmit power. It connects the shaft structure 3 and the clutch mechanism 4.

[0030] The intermediate gear 42 meshes with the internal gear ring 41 and the central gear 43. Therefore, when the intermediate gear 42 rotates around the internal gear ring 41, the intermediate gear 42 itself will also rotate. Therefore, an intermediate gear shaft 421 is provided on the intermediate gear 42. A connecting member 44 is provided on the periphery of the gear system structure. The connecting member 44 has the same rotation center as the internal gear ring 41 and the central gear 43. Multiple intermediate gears 42 are rotatably connected to the connecting member 44 through the intermediate gear shaft 421. When multiple intermediate gears 42 rotate in the central gear 43 and the internal gear ring 41, they will drive the connecting member 44 to rotate. The upper end of the connecting member 44 is connected to the inner barrel shaft 33. A second bearing 443 is provided on the outer side of the inner barrel shaft 33. The rotation direction of the inner barrel shaft 33 is the same as the rotation direction of the first impeller shaft 31.

[0031] To control the meshing relationship and driving force input of the gear train, a clutch mechanism 4 is connected to the gear train mechanism. The clutch mechanism 4 includes a first clutch drive shaft 422. The axis of the first clutch drive shaft 422 coincides with the rotation center of the internal gear ring 41 or the central gear 43, both lying on the same straight line. A second clutch drive shaft 442 is arranged around the first clutch drive shaft 422, without contact with the first clutch drive shaft 422. A clutch sleeve 46 is fixedly connected to the end of the first clutch drive shaft 422, and the clutch sleeve 46 is fitted onto the end of the second clutch drive shaft 442. 6 is internally equipped with a compression spring 454, which is used to press or release the clutch bushing 46 and the second clutch drive shaft 442. When the compression spring 454 presses the clutch bushing 46, the clutch bushing 46 and the second clutch drive shaft 442 are tightly engaged. When the compression spring 454 releases the clutch bushing 46, the clutch bushing 46 and the second clutch drive shaft 442 are not in contact. The second clutch drive shaft 442 is connected to the lower end of the connecting member 44. A first bearing 441 is provided on the outside of the second clutch drive shaft 442. When the compression spring 454 presses the clutch bushing 46, the rotation directions of the connecting member 44, the second clutch drive shaft 442 and the first clutch drive shaft 422 are the same.

[0032] In order to transmit the driving force of the clutch mechanism 4 to the gear train mechanism, the first clutch drive shaft 422 meshes with the intermediate gear 42 at one end near the internal gear ring 41, so that the motor 7 can transmit power to the gear train mechanism.

[0033] In order to ensure that the inner tub 111 does not rotate during washing, and the first impeller 13 and the second impeller 14 rotate in opposite directions, an embodiment of the present invention provides a braking device 45 on the connector 44. The braking device 45 includes a brake band 451 disposed on the connector 44. Under the drive of the braking device 45, the brake band 451 acts on the connector 44 to prevent the connector 44 from rotating.

[0034] refer to Figure 2 and Figure 3 When the washing machine enters the washing mode, the motor 7 starts, and the motor 7 inputs driving force to the clutch mechanism 4. The pressure spring 454 releases the clutch bushing 46, causing the first clutch drive shaft 422 to... With the second clutch drive shaft 442 in a disengaged state, the braking device 45 acts on the connecting member 44 through the brake band 451. Therefore, the second clutch drive shaft 442 is not driven by the motor 7, and the connecting member 44 and the inner barrel shaft 33 connected to the second clutch drive shaft 442 remain stationary. Correspondingly, the inner barrel 111 remains stationary. The first clutch drive shaft 422 transmits the driving force to the intermediate gear 42. The intermediate gear 42 begins to rotate under the action of the driving force. The center gear 43, which meshes with the intermediate gear 42, rotates in the same direction as the intermediate gear 42. The internal gear ring 41, which meshes with the intermediate gear 42, begins to rotate under the drive of the intermediate gear 42, and the rotation direction is opposite to that of the intermediate gear 42. The center gear 43 is connected to the first impeller shaft 31, and the internal gear ring 41 is connected to the second impeller shaft 32. At this time, the first impeller 13 and the second impeller 14 rotate in opposite directions.

[0035] When the clothes 8 are placed inside the washing machine, they are rubbed and washed by the first impeller 13 and the second impeller 14 at the bottom of the inner tub 111. The first impeller 13 creates a water flow in the inner tub 111. Driven by the water flow, the clothes 8 also rub against the biomimetic washboards 1111 distributed on the inner wall of the inner tub 111, cleaning the clothes 8 and effectively improving the cleaning effect of the washing machine. Furthermore, the inner tub 111 does not need to rotate. Since the inner tub 111 is full of water, if the inner tub 111 needs to be driven, the motor 7 needs to provide a lot of driving force, which will not only generate a lot of noise, but also reduce the life of the shaft mechanism 3, thus affecting the life of the washing machine. This not only reduces the user's experience of using the washing machine, but also increases the user's cost.

[0036] When the washing machine enters the spin-drying mode, the pressure spring 454 presses the clutch bushing 46, and the clutch bushing 46 grips the first clutch drive shaft 422 and the second clutch drive shaft 442. The first clutch drive shaft 422 and the second clutch drive shaft 442 are simultaneously driven by the motor 7 and rotate together in the same direction. At this time, the braking device 45 stops working, and the brake band 451 stops acting on the connecting piece 44. The second clutch drive shaft 442 is connected to the inner tub shaft 33 through the connecting piece 44. The three intermediate gears 42 rotate around the inner gear ring 41, and the rotation direction is the same as the rotation direction of the inner gear ring 41. In this state, the rotation direction of the connecting piece 44, the central gear 43 and the inner gear ring 41 is the same, and the rotation direction of the inner tub shaft 33, the second impeller shaft 32 and the first impeller shaft 31 is the same. At this time, the inner tub 111, the first impeller 13 and the second impeller 14 rotate together and rotate in the same direction. The clothes 8 in the inner tub 111 discharge water from the inner tub 111 while rotating at high speed.

[0037] Using the pulsator washing machine provided in this embodiment, the cleaning of clothes 8 is accomplished through the clutch structure 4, the counter-rotating first pulsator 13 and second pulsator 14, and the bionic washboard 1111. The gear system mechanism and clutch mechanism 4 increase the cost by approximately 50 yuan compared to the original, the first pulsator 13 and second pulsator 14 using plastic increases the cost by 3 yuan (if stainless steel is used, the cost is 12 yuan), and the bionic washboard 1111 can be molded based on the original inner tub; while the retail price of the product can be increased by 1,000 yuan compared to ordinary models. Based on a total sales volume of 100,000 units over 3 years, a gross profit of approximately 90 million yuan can be generated.

[0038] In an embodiment of the present invention, the compression spring 454 is controlled by a pawl 452 and a ratchet 453 disposed on the clutch bushing 46. The ratchet 453 controls the tension of the compression spring 454, while the pawl 452 acts on the ratchet 453 to control the ratchet 453 to release or lock the compression spring 454, thereby realizing the control of the gear system mechanism by the clutch mechanism 4.

[0039] In an embodiment of the present invention, a pulley 5 is provided at the lower end of the clutch bushing 46, and the motor 7 is connected to the pulley 5 via a belt to transmit driving force to the gear mechanism and the clutch mechanism 4.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
