Description

Technical Field

[0001] The utility model relates to the technical field of washing equipment, in particular to a washing machine clutch device and a washing machine. Background Art

[0002] The capacity of a micro-capacity fully automatic washing machine is generally around 0.5KG, and will not exceed 1KG at most. It can be used for separate washing of small pieces of clothing (socks, underwear, etc.). The washing method and requirements are relatively simple. Therefore, the overall structure of a micro-capacity fully automatic washing machine is relatively simple and the cost is relatively low. Specifically, a micro-capacity fully automatic washing machine generally includes an outer barrel for holding water, an inner barrel rotatably arranged in the outer barrel, a dehydration hole on the barrel wall of the inner barrel, and a driving motor connected to the inner barrel through a transmission shaft. The washing process and the dehydration process are both achieved by driving the inner barrel to rotate by the driving motor. Therefore, there are no different driving methods for the washing condition and the dehydration condition. Under the washing condition, the inner barrel rotates to form a water flow, and the inner barrel drives the clothes to rotate in the same direction as the water flow, so that the clothes in the inner barrel cannot be better washed by the rotating water flow, resulting in a lower washing ratio and the phenomenon that the clothes are not washed clean.

[0003] The main reason is that the existing small-capacity fully automatic washing machines are limited by production costs and are not equipped with a clutch mechanism to achieve the movement distinction between washing and dehydration conditions. It is impossible to lock the inner barrel in the washing condition and rotate the water flow through the impeller. In the dehydration condition, the inner barrel and the impeller rotate synchronously. Therefore, in order to improve the washing and dehydration effects of small-capacity fully automatic washing machines, some manufacturers have installed a deceleration clutch device of an ordinary fully automatic washing machine on small-capacity fully automatic washing machines. However, small-capacity fully automatic washing machines are limited by the size of the machine body. If the deceleration clutch device of an ordinary fully automatic washing machine is simply reduced in proportion and installed in a small-capacity fully automatic washing machine without targeted structural optimization, it will affect the capacity of the small-capacity fully automatic washing machine.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] The clutch device of the washing machine of the utility model is particularly suitable for a fully automatic pulsator washing machine with a small capacity. The overall structure of the clutch device of the washing machine is simple. By controlling the clutch sleeve to slide to engage with the fixed engaging teeth of the positioning plate, the inner barrel shaft sleeve is fixed.

[0039] See also Figure 1 and Figure 3 As shown, this embodiment provides a washing machine clutch device, comprising:

[0040] The inner barrel sleeve 200 has a first end and a second end;

[0041] The impeller shaft 100 is rotatably sleeved in the inner barrel shaft sleeve 200, and the impeller shaft 100 has a first end and a second end;

[0042] A clutch sleeve 1500 is axially slidably sleeved on the first end of the inner barrel shaft sleeve 200, the clutch sleeve 1500 and the inner barrel shaft sleeve 200 are circumferentially limited and assembled, and both ends of the clutch sleeve 1500 are respectively provided with meshing teeth;

[0043] A housing 300, wherein the housing 300 is provided with a mounting hole; the inner barrel sleeve 200 is rotatably inserted and sleeved in the mounting hole, wherein a first end of the inner barrel sleeve 200 is located below the housing 300, and a second end of the inner barrel sleeve 200 is located above the housing 300;

[0044] A positioning plate 1000 is fixedly mounted on the housing 300 , and a lower end surface of the positioning plate 1000 has fixed meshing teeth 1001 ;

[0045] The torque transmission sleeve 1600 is fixedly disposed at the second end of the impeller shaft 100 and is located below the clutch sleeve 1500;

[0046] And a clutch drive mechanism, used to drive the clutch sleeve 1500 to slide axially on the inner barrel sleeve 200, the clutch sleeve 1500 slides to engage with the fixed engaging teeth 1001 of the positioning plate 1000, the inner barrel sleeve 200 is fixed, the clutch sleeve 1600 slides to engage with the torque transmission sleeve 1600, and the inner barrel sleeve 200 rotates synchronously with the impeller shaft 100.

[0047] The washing machine clutch device of this embodiment is particularly suitable for fully automatic pulsator washing machines with small capacity. The overall structure of the washing machine clutch device is simple. By controlling the clutch sleeve 1500 to slide to engage with the fixed engaging teeth 1001 of the positioning plate 1000, the inner barrel sleeve 200 is fixed. In this way, the inner barrel of the washing machine connected to the inner barrel sleeve 200 is locked, so that the inner barrel of the washing machine is locked under washing or rinsing conditions, avoiding the inner barrel from rotating and improving the cleaning ratio of clothes; by controlling the clutch sleeve 1500 to slide to engage with the torque transmission sleeve 1600, the inner barrel sleeve 200 rotates synchronously with the pulsator shaft 100, so that the inner barrel of the washing machine connected to the inner barrel sleeve 200 and the pulsator of the washing machine connected to the pulsator shaft 100 rotate in the same direction and at the same speed under dehydration conditions.

[0048] Therefore, the clutch device of the washing machine in this embodiment realizes two clutch states, namely, locking of the inner barrel sleeve 200 and synchronous rotation of the inner barrel sleeve 200 and the impeller shaft 100, through the sliding of the clutch sleeve 1500, corresponding to the washing or rinsing condition and the dehydration condition of the washing machine. The clutch device of the washing machine does not have a reduction gear system, but only has one set of clutch mechanism. The overall structure is simple, easy to assemble, and the cost of the whole machine is low. It is particularly suitable for small-capacity washing machines.

[0049] In addition, in the washing machine clutch device of the present embodiment, the positioning plate 1000 is a separate structural component, which is fixedly installed on the shell 300. In order to ensure the structural strength of the engagement between the clutch sleeve 1500 and the fixed meshing teeth 1001, the positioning plate 1000 can be made of a material with higher strength, thereby reducing the force on the shell 300. Therefore, the overall axial dimension of the shell 300 is reduced, thereby reducing the entire axial dimension of the washing machine clutch device, reducing the axial space occupied by the washing machine clutch device in the small-capacity washing machine, and reducing the influence of the washing machine clutch device on the capacity of the small-capacity washing machine.

[0052] Since the thickness of the housing 300 of this embodiment is reduced, the installation of the rolling bearing 1200 is achieved by forming a bearing mounting seat 303. Specifically, the rolling bearing 1200 of this embodiment is arranged in a single group.

[0053] Furthermore, since the thickness of the shell 300 of this embodiment is reduced, in order to ensure the strength of the bearing mounting seat 303 of the shell 300, the shell 300 described in this embodiment includes an annular portion 301 and an inner recess 302, and the inner recess 302 connects the annular portion 301 and the bearing mounting seat 303.

The two ends of the shift fork spring 1800 are respectively fixedly connected to the second end 1703 of the shift fork 1700 and the positioning plate 1000, and the shift fork spring 1800 is in a compressed state. The rotating motor 600 drives the rotating pressure block 500 to rotate, and the rotating pressure block 500 abuts against the second end of the shift fork 1700. The rotating pressure block 500 and the shift fork spring 1800 are located on both sides of the second end 1703 of the shift fork 1700.

In addition, the torque transmission sleeve 1600 of this embodiment has torque transmission sleeve meshing teeth, the clutch sleeve 1500 slides upward along the axial direction of the inner barrel sleeve 200, the clutch sleeve upper meshing teeth 1502 of the clutch sleeve 1500 mesh with the fixed meshing teeth 1001 of the positioning plate 1000, and the inner barrel sleeve 200 is fixed; the clutch sleeve 1500 slides downward along the axial direction of the inner barrel sleeve 200, the clutch sleeve lower meshing teeth 1503 of the clutch sleeve 1500 mesh with the torque transmission sleeve meshing teeth of the torque transmission sleeve 1600, and the inner barrel sleeve 200 is fixedly connected with the dehydration shaft 100, and the two rotate synchronously under the drive of the drive motor 400.

[0059] The clutch sleeve 1500 described in this embodiment can slide up and down along the axial direction on the inner barrel sleeve 200, but cannot rotate circumferentially relative to it. As an optional implementation scheme of this embodiment, an inner barrel sleeve external spline extending along the axial direction is provided on the outer wall surface of the first end of the inner barrel sleeve 200 described in this embodiment, and a clutch sleeve internal spline is provided on the inner wall surface of the center through hole of the clutch sleeve 1500, and the clutch sleeve internal spline is relatively slidably matched with the inner barrel sleeve external spline.

[0061] The clutch drive mechanism described in this embodiment drives the clutch sleeve 1500 to slide upward along the axial direction of the inner barrel sleeve 200 until it engages with the fixed meshing teeth 1001 of the positioning plate 1000, and the compression spring 900 is compressed and deformed; the clutch drive mechanism is separated from the clutch sleeve 400, and the compressed and deformed compression spring 900 returns to its initial state, acting on the clutch sleeve 1500 to drive the clutch sleeve 1500 to slide downward along the axial direction of the inner barrel sleeve 200 until it engages with the torque transmission sleeve 1600.

[0062] In this embodiment, the return movement of the clutch sleeve 1500 is achieved by compressing the spring 900, so that the clutch drive mechanism only needs to achieve unidirectional movement of the clutch sleeve 1500, and the clutch drive mechanism only needs to achieve a single movement, which has a simpler structure and lower cost.

[0063] As an optional implementation of this embodiment, a clutch device for a washing machine in this embodiment includes a motor mounting frame 1300, the motor mounting frame 1300 is fixed on the housing 300, and the driving motor 400 of the washing machine is fixedly mounted on the housing 300 through the motor mounting frame 1300.
