Description

Technical Field

[0001] The present invention relates to the technical field of laundry equipment, and in particular to a washing machine speed reduction clutch device, a washing machine and a control method thereof. Background Art

[0002] Washing machines, as a household appliance, have gradually become an indispensable part of people's lives, and fully automatic pulsator washing machines, as a major type of washing machine, are increasingly widely used. The working mode of existing fully automatic pulsator washing machines is generally that during washing and rinsing, the driving device drives the pulsator of the washing machine to rotate forward and reverse through a reduction clutch device, and during dehydration, the driving device drives the pulsator and the washing tub of the washing machine to rotate synchronously at high speed through a reduction clutch device.

[0003] However, with the rapid development of science and technology, the existing fully automatic pulsator washing machine's washing method that simply relies on the pulsator to stir the water flow has increasingly limited effect on improving the washing effect of clothes. Therefore, how to increase the washing diversity of the fully automatic pulsator washing machine to improve the washing effect has become a technical problem that needs to be solved urgently.

[0004] Some patents have proposed solutions to this problem. For example, the Chinese invention patent with application number: 02804912.8, entitled "A transmission mechanism for generating bidirectional rotation, a washing machine and method for generating bidirectional washing, and a related inner barrel and agitator", discloses a transmission mechanism for generating bidirectional drive suitable for use in a washing machine, comprising a power input end and two power output ends, wherein one power output end is connected to an agitator shaft (10) and causes the agitator shaft to rotate in a first direction; and the other power output end is connected to an inner barrel shaft (11) and causes the inner barrel shaft to rotate in a second direction opposite to the first direction. A washing machine for generating bidirectional washing and a washing method capable of generating bidirectional washing in a washing machine. An agitator and inner barrel for a washing machine. The patent discloses a transmission mechanism capable of generating bidirectional drive in a washing machine, and discloses the specific structure of the transmission mechanism in the specification. It can be seen from the contents of the specification and the drawings that the patent solves the problem of a single power drive mode in existing fully automatic pulsator washing machines to some extent, but the transmission mechanism disclosed in the patent has a complex structure, high difficulty in manufacturing and assembly, and high manufacturing cost.

[0005] Another example is the Chinese invention patent application with application number: 201310408108.X and title: Fully automatic washing machine. The invention discloses a fully automatic washing machine, including an outer barrel, an inner barrel, a pulsator and a driving device. The driving device includes at least two rotors and at least one stator, wherein one rotor is connected to the inner barrel shaft, and another rotor is connected to the pulsator shaft. The driving device is a variable frequency direct drive motor, wherein the rotor, stator, inner barrel shaft and pulsator shaft are coaxially arranged, the inner barrel shaft is hollow, and the pulsator shaft is arranged in the inner barrel shaft. When the washing machine washes, the pulsator and the inner barrel rotate in the same direction, or rotate in opposite directions, or one of the pulsator and the inner barrel rotates, and when dehydrating, the pulsator and the inner barrel rotate in the same direction and at the same speed. The washing machine described in the invention is connected to the inner barrel shaft and the pulsator shaft respectively through two rotors, and the inner barrel and the pulsator are driven to rotate respectively through the double rotors. This structure greatly reduces the weight, volume and cost of the driving system, and improves the transmission efficiency and stability.

[0006] From the above two published patent application documents, it can be seen that there are two main ideas for solving the water flow diversity of washing machines: Method 1, designing a deceleration clutch device that can output bidirectional power to achieve bidirectional washing in the washing process of the washing machine and enhance the water flow effect; Method 2, designing a driving motor with bidirectional power output to drive the impeller and the inner drum respectively to achieve bidirectional washing in the washing process of the washing machine and enhance the water flow effect. The above method 1 has the disadvantages of complex structure of the deceleration clutch device, difficult installation and complex control method, and method 2 has the disadvantage of high cost of the driving motor with bidirectional power output.

[0007] In addition, the method of using a deceleration clutch device to switch between multiple washing modes of the washing machine requires that the clutch mechanism of the deceleration clutch device be maintained in the meshing state corresponding to the multiple washing modes respectively. The existing method uses a multi-stroke motor to drive the clutch mechanism to switch the meshing state corresponding to the multiple washing modes. However, the multi-stroke motor cannot lock the clutch mechanism, and the engagement stability of the clutch mechanism is not good.

[0008] In view of this, the present invention is proposed. Summary of the invention

[0042] The deceleration clutch device of the washing machine of this embodiment is connected by a transmission between the power component 20 and the crank connecting rod mechanism. The rotation output of the power component 20 is converted into reciprocating motion in the vertical direction through the crank connecting rod mechanism. The reciprocating motion of the crank connecting rod mechanism in the vertical direction drives the shift fork 14 to shift the clutch sleeve 9 to reciprocate for clutch switching. This embodiment controls the shift fork 14 to shift the clutch sleeve 9 to various clutch positions by controlling the rotation angle of the power component 20, thereby improving the precision of the shift fork's movement, high reliability, and simple overall structure. Moreover, by controlling the multiple rotation angles of the power component 20, the shift fork 14 shifts the clutch sleeve 9 to multiple clutch positions, so as to achieve a corresponding more washing modes, improve the diversity of washing, and have a better clothing washing effect.

[0043] Furthermore, in order to convert the rotational output of the power component 20 into reciprocating motion in the vertical direction, the crank-connecting rod mechanism of the present embodiment includes a transmission wheel 21 and a transmission rod 22, wherein the transmission wheel 21 is arranged on the rotational output end of the power component 20, one end of the transmission rod 22 is eccentrically connected to the transmission wheel 21 through a first hinge 23, and the other end of the transmission rod 22 is connected to the fork 14 through a second hinge 24.

[0047] The power component 20 has a third limit position. The rotation output end of the power component 20 drives the transmission wheel 21 to rotate to the third position C. The transmission wheel 21 drives the transmission rod 22 to drive the shift fork 14 to shift the clutch sleeve 9 to engage with the fixed sleeve 8.

[0048] The power component 20 of this embodiment has at least three limit positions, namely, a first limit position, a second limit position, and a third limit position, and the corresponding clutch sleeve 9 has at least three clutch states. At least three washing modes can be realized on the washing machine. Compared with the existing washing machines, the washing modes are enriched. Users can choose a more suitable washing mode according to specific washing needs, which has a better washing effect and enhances the user's washing experience.

[0049] Furthermore, in order to achieve various clutch positions of the clutch sleeve 9, this embodiment further defines three limit positions of the power component, specifically:

[0050] The first limit position of the power component satisfies that: when the rotation output end of the power component rotates to the first limit position, the transmission wheel drives the first hinge to move to the upper end of the transmission wheel with the vertical diameter facing upward;

[0051] The second limit position of the power component satisfies that: when the rotation output end of the power component rotates to the second limit position, the transmission wheel drives the first hinge to move to any one end of the transmission wheel in the horizontal radial direction;

[0052] The third limit position of the power component satisfies that: when the rotation output end of the power component rotates to the third limit position, the transmission wheel drives the first hinge to move to the lower end of the transmission wheel with the vertical diameter facing upward.

[0053] As an implementation mode of this embodiment, the fork assembly described in this embodiment includes a fixed fork seat 6, the middle part of the fork 14 is rotatably mounted on the fork seat 6, and the fork 14 has a driving end 18 connected to the transmission rod 22 and a forked end 17 forked on the clutch sleeve 9; a transmission connecting component 19 is fixedly arranged on the driving end 18, and the end of the transmission rod 22 is connected to the transmission connecting component 19 through a second hinge 24.

[0054] Specifically, the transmission connection component 19 is a connecting bolt, and a through hole is provided on the driving end 18 of the fork 14.

[0058] In the existing fully automatic washing machine, the brake wheel is in a braking state during washing, and the deceleration clutch device can only drive the pulsator to rotate. During dehydration, although the brake wheel can rotate, it can only maintain unidirectional rotation due to the limitation of the one-way bearing.
