The power unit 200 is suitable for being connected with the third moving member 4 to drive the third moving member 4 to move, the transmission mechanism 100 directly drives the third moving member 4 to move through the power unit 200, and can drive one of the first moving member 2 and the second moving member 3 to move through the movement of the third moving member 4, so that the structure is simplified and the cost is reduced by adopting one power unit 200 to realize the movement of the first moving member 2, the second moving member 3 and the third moving member 4.

When the third moving member 4 drives the first moving member 2 to move, the first moving member 2 can drive the first control member 301 to move, so that the working state of the first execution unit 300 can be adjusted, and the working mode of the washing machine can be adjusted. When the third moving member 4 drives the second moving member 3 to move, the second moving member 3 can drive the second control member to move, so that the working state of the second execution unit 400 can be adjusted, and the working mode of the washing machine can be adjusted. After the third moving member 4 drives the first moving member 2 to move a certain distance, the third moving member 4 drives the second moving member 3 to move, so that the working state of the first executing unit 300 and the working state of the second executing unit 400 can be adjusted, and the working mode of the washing machine can be adjusted.

It should be noted that, when the first execution unit 300 is in different operation states, the washing machine has different operation modes; when the second execution unit 400 is in different operation states, the washing machine has different operation modes; the washing machine also has different operation modes when the first and second execution units 300 and 400 are both in different operation states. It follows that by moving the third moving member 4, one of the first moving member 2 and the second moving member 3 is driven to move, so that the washing machine can be switched to different operation modes.

The limiting component is used for limiting the first moving part 2 at a set position, when the first moving part 2 needs to be kept at the set position, the power unit 200 can be powered off when the first moving part 2 moves to the set position or moves to the rear side of the set position, the limiting component can limit the first moving part 2 at the set position, and at the moment, the third moving part 4 is kept at the set position with the first moving part 2. Through setting up spacing subassembly, spacing in the settlement position with first moving part 2, need not to realize spacing in the settlement position with first moving part 2 through the circular telegram to power unit 200 to can be under the circumstances that power unit 200 is cut off, spacing in the settlement position with first moving part 2 through spacing subassembly, can make washing machine keep under corresponding mode, can practice thrift the energy consumption.

In some embodiments, the transmission mechanism may include: the triggering component can be triggered by the first moving piece 2 when the first moving piece 2 moves to at least the set position, and the power unit 200 is powered off. Therefore, through the trigger assembly, and through the trigger assembly triggered in the process that the first moving part 2 moves along the first direction, the electric control board of the washing machine can receive corresponding signals, so that the power unit 200 can be conveniently and timely controlled to be powered off.

The transmission mechanism 100 can distribute the driving action of the power unit 200, so that one of the first moving member 2 and the second moving member 3 can be driven to move through the movement of the third moving member 4 at a specific position and time, so that the washing machine has more kinds of working modes, the working states of the first execution unit 300 and the second execution unit 400 can be adjusted, the adjustment of the working modes of the washing machine can be conveniently realized, more washing demands of users can be met, the integral structure of the washing machine is facilitated, and the control cost is reduced. In addition, through the spacing subassembly that sets up, under the circumstances that power unit 200 is disconnected, can conveniently be with first moving part 2 spacing in the settlement position, can practice thrift the energy consumption.

In some embodiments of the present invention, the starting position of the third moving member 4 in the first direction is an initial position, the final position of the third moving member 4 in the first direction is an end position, and the first moving member 2 has an end position between the initial position and the end position in the first direction. During the process that the third moving member 4 moves from the initial position to the end position along the first direction, the third moving member 4 drives the first moving member 2 to move to the end position along the first direction, and the first moving member 2 is kept at the end position; during the movement of the third movement member 4 in the first direction from the end position to the end position, the third movement member 4 brings the second movement member 3 to the end position, wherein the set position is located between the initial position and the end position or the set position includes the end position. In the process that the third moving element 4 moves to the end position, the third moving element 4 can be brought to the first moving element 2 to move to the end position, and as the first moving element 2 moves to the end position and is kept at the end position, in the process that the third moving element 4 starts to move backwards from the end position, the third moving element 4 does not drive the first moving element 2 to move, and the third moving element 4 drives the second moving element 3 to move to the end position, so that the third moving element 4 can drive one of the first moving element 2 and the second moving element 3 to move in the moving process, and the corresponding adjustment of the working mode is realized.

In addition, in the process that the third moving member 4 moves from the initial position to the end position, the third moving member 4 can drive the first moving member 2 to synchronously move, and as the first moving member 2 moves to drive the first control member 301 to move, the working state of the first executing unit 300 can be adjusted, and thus the working mode of the washing machine can be adjusted, and the power unit 200 can be powered off and can stop and keep the first moving member 2 at a certain set position between the initial position and the end position or stop and keep the first moving member 2 at the end position through the limiting assembly according to requirements, and when one moving member 2 stops and keeps at different positions, the first executing unit 300 has different working states, so that the working modes of the washing machine can be further enriched.

For example, in some embodiments of the present invention, the third moving member 4 has an initial position, a first position, a second position, and an end position that are sequentially arranged at intervals in the first direction, the first position and the second position being located between the initial position and the end position and the second position being located on one side of the first position adjacent to the end position. The first movement element 2 has a terminating position in the first direction, which is located at the second position or which is located between the second position and the terminating position and adjacent to the second position.

The limiting component is used for limiting the first moving part 2 at one of a first position and a second position, when the first moving part 2 needs to be kept at the first position, the limiting component can limit the first moving part 2 at the first position when the first moving part 2 moves to the first position, and at the moment, the third moving part 4 also keeps at the first position with the first moving part 2; when the first moving member 2 needs to be kept at the second position, the limiting assembly can limit the first moving member 2 at the second position when the first moving member 2 moves to the second position, and the third moving member 4 is kept at the second position with the first moving member 2. When the first moving member 2 is located at the initial position and needs to be kept at the initial position, the limiting action of the limiting assembly is not needed when the power unit 200 does not work, the first moving member 2 can be kept at the initial position, and the third moving member 4 is also kept at the initial position; when the third moving member 4 moves to the end position, the third moving member 4 can be kept at the end position by the action of the power unit 200, so that the second moving member 3 and the third moving member 4 are kept at the position. Through the spacing subassembly that sets up, with first moving part 2 spacing in one of first position and second position, need not to realize spacing first moving part 2 in one of first position and second position through the circular telegram to power unit 200, can practice thrift the energy consumption.

When the third moving member 4 drives the first moving member 2 to move to the first position or between the first position and the second position, the power unit 200 can be powered off, the limiting component can keep the first moving member 2 at the first position in a limiting manner, and at the moment, the first moving member 2 drives the first control member 301 to move to the first control angle, so that the working state of the first execution unit 300 is changed, and the working mode of the washing machine can be adjusted.

When the third moving member 4 drives the first moving member 2 to move to the second position or between the second position and the end position, the power unit 200 can be powered off, the limiting component can limit and keep the first moving member 2 at the second position, and at the moment, the first moving member 2 drives the first operating member 301 to move to the second control angle, so that the working state of the first executing unit 300 is further changed, and the working mode of the washing machine can be further adjusted. Like this when third moving part 4 drives first moving part 2 and moves to different positions for power unit 200 outage just keeps first moving part 2 spacing on different settlement positions through spacing subassembly, can make washing machine adjustment to different operating modes for washing machine's operating mode is richer and the switching between the different operating modes is convenient.

In some embodiments, the third movement element 4 further comprises a driving position for starting to move the second movement element 3, the driving position being located at the end position or the driving position being located between the end position and said end position and adjacent to the end position. In the process that the third moving member 4 moves from the initial position to the end position, the third moving member 4 drives the first moving member 2 to move in the first direction and the second moving member 3 is not moved, so that the working state of the first execution unit 300 can be adjusted, and the working state of the second execution unit 400 is kept unchanged, thereby adjusting the working mode of the washing machine; in the process that the third moving member 4 moves from the driving position to the end position, the third moving member 4 drives the second moving member 3 to move in the first direction, and the first moving member 2 is not moved in the first direction, so that the working state of the second execution unit 400 can be adjusted, and the working state of the first execution unit 300 is kept unchanged, thereby adjusting the working mode of the washing machine. When the driving position is located between the end position and is adjacent to the end position, neither the first moving member 2 nor the second moving member 3 is moved in the first direction during the movement of the third moving member 4 from the end position to the driving position, during which the first moving member 2 can be moved in the second direction (refer to the e2 direction in the drawing), which is perpendicular to the first direction.

In some embodiments, power unit 200 may be a single-stroke retractor, for example, power unit 200 may be a 45mm single-stroke retractor, wherein the distance between the initial position and the first position may be 15mm, the distance between the first position and the second position may be 15mm, and the distance between the second position and the end position may be 15mm. Wherein, the third moving member 4 may be formed with a traction groove 42, and the power unit 200 and the third moving member 4 may be connected by a traction rope 201, and a rope end of the traction rope 201 may be fastened to the traction groove 42, so as to realize connection between the power unit 200 and the third moving member 4.

When the end position is located between the second position and the end position and is adjacent to the second position, the dimensional error and the assembly error of the component can be allowed to exist within a certain range, the processing difficulty is reduced, and the stroke accuracy can be prevented from being influenced due to the dimensional error and the assembly error, so that the working accuracy of the transmission mechanism 100 is influenced. In some embodiments, when the ending position is located between and adjacent to the second position, the distance between the ending position and the second position in the first direction ranges from 0.8 mm to 1.5mm, e.g., the distance between the ending position and the second position may be 1mm. By setting the distance between the end position and the second position to between 0.8 and 1.5mm, machining and assembly errors can be met without affecting the working state of the first actuating element, i.e. the working state of the first actuating element is identical when the first moving element 2 is in the second position and the end position.

In some embodiments, when the driving position is located between and adjacent to the end position, the component dimension error and the assembly error can be allowed to exist within a certain range, the processing difficulty can be reduced, and the stroke accuracy can be prevented from being influenced due to the dimension error and the assembly error, thereby influencing the working accuracy of the transmission mechanism 100. In some embodiments, the distance between the drive position and the end position in the first direction when the drive position is located between the end position and adjacent the end position is in the range of 0.8-1.5mm, e.g. the distance between the drive position and the end position may be 1mm. By setting the distance between the drive position and the end position to between 0.8 and 1.5mm, machining and assembly errors can be met without affecting the third movement element 4 to drive the second movement element 3 to move a sufficient distance to change the working state of the second execution element.

For example, the first execution unit 300 may have a first operating state, a second operating state, and a third operating state, and the second execution unit 400 may have a first state and a second state. When the third mover 4 is at the initial position, the power unit 200 is not operated, and the first execution unit 300 is in the first operating state and the second execution unit 400 is in the first state, and the washing machine may be in the first operating mode (refer to fig. 2 to 5).

The power unit 200 works, the third moving member 4 is driven to move, the third moving member 4 moves while driving the first moving member 2 to move along the first direction, when the third moving member 4 moves at least to the first position, the power unit 200 can be powered off at this time, so that the power unit 200 does not work, the first moving member 2 is limited at the first position through the effect of the limiting component, and the third moving member 4 and the first moving member 2 are limited together at the first position, at this time, the working state of the first executing unit 300 is changed to the second working state, the working state of the second executing unit 400 is kept at the first state, and the washing machine can be in the second working mode (refer to fig. 6 and 7). Wherein the movement of the third mover 4 at least to the first position may include: the third movement 4 is moved to the first position or the third movement 4 is moved between the first position and the second position, for example when the movement of the third movement 4 at least to the first position comprises the movement of the third movement 4 between the first position and the second position, the movement of the third movement 4 between the first position and the second position and adjacent to the first position.

The power unit 200 works, the third moving member 4 is driven to move, the third moving member 4 moves while driving the first moving member 2 to move along the first direction, when the third moving member 4 moves at least to the second position, the power unit 200 can be powered off at this time, so that the power unit 200 does not work, the first moving member 2 is limited to the second position through the effect of the limiting component, the third moving member 4 and the first moving member 2 are limited to the second position together, at this time, the working state of the first execution unit 300 is further changed to the third working state, the working state of the second execution unit 400 is kept to the first state, and the washing machine can be in the third working mode (refer to fig. 8 and 9). Wherein the movement of the third mover 4 at least to the second position comprises: the third movement member 4 is moved to the second position or the third movement member 4 is moved between the second position and the end position, for example when the movement of the third movement member 4 at least to the second position comprises the movement of the third movement member 4 between the second position and the end position, the movement of the third movement member 4 between the second position and the end position is adjacent to the second position.

When the power unit 200 operates to drive the third moving member 4 to move to the end position, the third moving member 4 drives the second moving member 3 to move and maintain the position, the power unit 200 maintains the power on, the second moving member 3 maintains at the end position, at this time, the operation state of the first executing unit 300 maintains at the third operation state, and the operation state of the second executing unit 400 changes to the second state, at this time, the washing machine may be in the fourth operation mode (refer to fig. 10 and 11).

In some embodiments, the first execution unit 300 includes a first elastic reset element for resetting the first control element 301, and drives the first moving element 2 to reset when the first control element 301 resets, so that the first moving element 2 can be reset to an initial position; the second execution unit 400 comprises a second elastic reset piece for resetting the second control piece, and drives the second moving piece 3 to reset when the second control piece resets; the third moving member 4 is reset under the drive of at least one of the first moving member 2 and the second moving member 3. Thereby, the reset of the entire transmission 100 can be achieved.

For example, in the second operation mode of the washing machine, if the transmission mechanism 100 is to be reset, the first moving member 2 and the limiting component are disengaged, so that the power unit 200 does not work, the first elastic reset member drives the first operation member 301 to reset, so as to drive the first moving member 2 to move reversely and reset to the initial position, and meanwhile, the first moving member 2 can drive the third moving member 4 to move reversely and reset to the initial position together, so that the reset of the transmission mechanism 100 can be realized.

For another example, in the third working mode of the washing machine, if the transmission mechanism 100 is to be reset, the first moving member 2 and the limiting component are disengaged, so that the power unit 200 does not work, the first elastic reset member drives the first operation member 301 to reset, so as to drive the first moving member 2 to reversely move and reset to the initial position, and meanwhile, the first moving member 2 can drive the third moving member 4 to reversely move together and reset to the initial position, so that the reset of the transmission mechanism 100 can be realized.

For example, in the fourth working mode of the washing machine, if the transmission mechanism 100 is to be reset, the first moving member 2 and the limiting component are disengaged, the power unit 200 is not working, the second elastic reset member drives the second control member to reset, so as to drive the second moving member 3 to move reversely to reset, the third moving member 4 is driven to move reversely in the process of moving the second moving member 3 reversely, and when the third moving member 4 moves reversely to the final position, the first elastic reset member can drive the first control member 301 to reset, so as to drive the first moving member 2 to move reversely and reset to the initial position, and meanwhile, the first moving member 2 can drive the third moving member 4 to move reversely and reset to the initial position together, so that the reset of the transmission mechanism 100 can be realized.

In some embodiments, referring to fig. 19-20 in combination with fig. 2-10, the third moving member 4 has a drop-preventing protrusion 41, the drop-preventing protrusion 41 is located on a side of the first moving member 2 adjacent to the power unit 200 in the first direction, the drop-preventing protrusion 41 is adapted to abut against the first moving member 2, for example, a portion of the side wall of the first moving member 2 adjacent to the power unit 200 in the first direction may constitute a first limiting surface 213 adapted to abut against the drop-preventing protrusion 41. For example, between the initial position and the end position, the drop-preventing protrusion 41 may abut against the first moving member 2; between the end position and the end position, the drop-off prevention protrusion 41 can be separated from the first moving member 2. Therefore, when the third moving member 4 is located at the end position, if the transmission mechanism 100 needs to be reset, the third moving member 4 moves reversely under the driving of the second moving member 3, and when the anti-falling protrusion 41 of the third moving member 4 abuts against the first moving member 2, the limiting effect on the third moving member 4 can be achieved, so that the third moving member 4 is prevented from moving reversely too much under the action of the second elastic reset member to affect the normal reset of the transmission mechanism 100.

The transmission mechanism 100 and the washing machine having the transmission mechanism 100 will be described below by taking the washing machine as an example of the washing machine.

In this embodiment, the operation modes of the washing machine may include a normal washing mode, a double-drive washing mode, a new water flow washing mode and a dewatering and draining mode, wherein the normal washing mode is the first operation mode, the double-drive washing mode is the second operation mode, the new water flow washing mode is the third operation mode, and the dewatering and draining mode is the fourth operation mode. The washing machine comprises a casing, an inner barrel 500 and a pulsator, wherein the inner barrel 500 is rotatably arranged in the casing, the pulsator is rotatably arranged in the inner barrel 500, the first execution unit 300, the second execution unit 400 and the transmission mechanism 100 are all arranged in the casing, the first execution unit 300 is connected with the inner barrel 500 and the pulsator, and the second execution unit 400 can be opened and closed to discharge washing water.

The first actuating unit 300 may be a clutch assembly, and the first actuating unit 301 may be a clutch lever of the clutch assembly, and the clutch assembly further includes a clutch brake for controlling the inner tub 500 and a wrap spring for controlling a clutch relationship between the pulsator and the inner tub 500. When the clutch brake is released, the inner barrel 500 is in a free state, and when the pulsator rotates, the pulsator disturbs water flow in the inner barrel 500 to move, so that the inner barrel 500 can be driven to reversely rotate; when the clutch is braked and held tightly, the inner barrel 500 is in a locked state, and the inner barrel 500 cannot be driven to rotate when the wave wheel rotates. When the arming spring is released, the impeller is separated from the inner barrel 500, and the impeller cannot drive the inner barrel 500 to rotate when rotating; when the armful spring is enclasped, the impeller is matched with the inner barrel 500, and the impeller can drive the inner barrel 500 to rotate when rotating.

Specifically, when the clutch brake is released and the arming spring is released, the inner barrel 500 is in a free state, and when the pulsator rotates, the washing water in the inner barrel 500 is driven to move, so that the inner barrel 500 can be driven to reversely rotate; when the clutch is released and the spring is held tightly, the wave wheel rotates to drive the inner barrel 500 to synchronously rotate; when the clutch is held tightly and the holding spring is released, the inner barrel 500 is locked and immobilized, and only the pulsator rotates at this time.

The second execution unit 400 may be a drain valve, the second control element may be a valve body of the drain valve, the state of the second execution unit 400 is changed by moving the second control element, the second execution unit 400 has an open state (the second state described above) and a closed state, the inner tub 500 may drain the washing water when the second execution unit 400 is in the open state (the first state described above), and the washing water in the inner tub 500 may not drain through the drain valve when the second execution unit 400 is in the closed state.

Referring to fig. 2 to 5, when it is required to put the washing machine in the normal washing mode, the power unit 200 is not operated, the third moving member 4 is at the initial position, and the third moving member 4 is not moved, so that the first moving member 2 and the second moving member 3 are not moved, and thus, the clutch lever (first operation member 301) of the clutch assembly (first execution unit 300) and the valve core (second operation member) of the drain valve (second execution unit 400) are not moved, at this time, the drain valve is closed and the clutch lever is at the initial control angle, and when the clutch brake is tightened and the wrap spring is released, the pulsator is separated from the inner tub 500 and the inner tub 500 is locked and is only rotated, thereby achieving normal washing.

Referring to fig. 6 and 7, when the washing machine is required to be in the double-drive washing mode, the power unit 200 works, drives the third moving member 4 to move and drives the first moving member 2 to synchronously move, when the third moving member 4 moves to at least the first position, the power unit 200 is powered off, the first moving member 2 is kept at the first position through the limiting assembly, and in the process, the second moving member 3 is not moved, and the drain valve is closed. The clutch driving lever rotates to a first control angle, the clutch brake is released and the holding spring is released, the inner barrel 500 is in a free state, and when the pulsator rotates, the washing water in the inner barrel 500 is driven to move, so that the inner barrel 500 can be driven to reversely rotate, and the hand rubbing washing effect can be realized. It should be noted that, when the power unit 200 drives the third moving member 4 to move between the first position and the second position, the first moving member 2 moves together with the third moving member 4 to move between the first position and the second position, when the power unit 200 is powered off, the first operating member 301 drives the first moving member 2 to move reversely due to the reset trend of the first operating member 301 under the action of the first elastic reset member, and when the first moving member 2 moves reversely to the first position, the first moving member 2 is limited at the first position by the limiting effect of the limiting component, and the third moving member 4 moves reversely to the first position along with the first moving member 2 and is kept at the first position.

Referring to fig. 8 and 9, when the washing machine is required to be in a new water flow washing mode, the power unit 200 works, drives the third moving part 4 to move and drives the first moving part 2 to synchronously move, when the third moving part 4 at least moves to the second position, the power unit 200 is powered off, the first moving part 2 is kept at the second position through the limiting component, the second moving part 3 is not moved in the process, the clutch brake is released, the wave wheel is tightly held with the inner barrel 500, the wave wheel rotates to drive the inner barrel 500 to synchronously rotate, thereby tornado water flow can be realized, the water flow impact force in the inner barrel 500 is large, and water in the inner barrel 500 can climb up along the inner wall of the inner barrel 500 under the action of centrifugal force, so that a better washing effect is achieved. It should be noted that, when the power unit 200 drives the third moving member 4 to move between the second position and the final position, the first moving member 2 moves together with the third moving member 4 to move between the second position and the final position, for example, the first moving member 2 moves to the final position or moves between the second position and the final position, when the power unit 200 is powered off, because the first operating member 301 has a reset tendency under the action of the first elastic reset member, the first operating member 301 drives the first moving member 2 to move reversely, and when the first moving member 2 moves reversely to the second position, the first moving member 2 is limited to the second position by the limiting action of the limiting component, and the third moving member 4 moves reversely with the first moving member 2 to the second position and remains at the second position.

Referring to fig. 10 and 11, when it is required to put the washing machine in the dehydrating and draining mode, the power unit 200 operates to drive the third moving member 4 to move to the end position and drive the second moving member 3 to move, the power unit 200 maintains the power to keep the third moving member 4 at the end position, the first moving member 2 is kept at the end position, the first moving member 2 is stationary (when the end position is at the second position) during the process, or the first moving member 2 moves together with the third moving member 4 from the second position to the end position and is stopped at the end position during the process from the end position to the end position, the drain valve is opened when the clutch brake is released and the holding spring is held tightly, and the pulsator rotates to drive the inner tub 500 to rotate synchronously, so that dehydrating and draining can be realized.

When the washing machine washes laundry, any one of a normal washing mode, a double-drive washing mode, and a new water flow washing mode may be performed according to a user selection, and a plurality of washing modes (at least two of the normal washing mode, the double-drive washing mode, and the new water flow washing mode) may be performed. The washing mode of the washing machine may be input by a user through a control panel or may be a washing mode previously written in an electronic control board of a control device of the washing machine.

In some embodiments, the washing power of the normal washing mode, the double-drive washing mode, and the new water flow washing mode is sequentially increased, and when the washing machine performs a plurality of washing modes, a washing mode having a low washing power may be preferentially performed. For example, when the washing machine includes the above two washing modes, the washing mode having a lower washing strength may be performed first, and then the washing mode having a higher washing strength may be performed; when the washing machine comprises the three washing modes, the washing mode with the lowest washing force can be executed first, then the washing mode with higher washing force is executed, and finally the washing mode with the highest washing force is executed to obtain the washing mode.

In addition, through the spacing subassembly that sets up, under the circumstances that power unit 200 was cut off the power supply, can conveniently be with first moving part 2 spacing in first position or second position, can practice thrift the energy consumption.

In the process that the first moving member 2 moves from the initial position to the first position, the first limiting member 61 moves to avoid the first moving member 2, so that the first moving member 2 can smoothly move along the first direction in the process that the power unit 200 drives the third moving member 4 to move to drive the first moving member 2 to move along the first direction, and the first limiting member 61 is prevented from obstructing the first moving member 2. When the first moving member 2 is located at the first position, for example, when the power unit 200 drives the third moving member 4 to move to drive the first moving member 2 to move to the first position along the first direction, the power unit 200 is powered off, or when the power unit 200 drives the third moving member 4 to drive the first moving member 2 to move between the first position and the second position along the first direction, the power unit 200 is powered off, and when the first moving member 2 moves to the first position in the reverse direction, the first limiting member 61 cooperates with the first moving member 2 to limit the first moving member 2 at the first position, so that when the power unit 200 is powered off, the first moving member 2 can be kept at the first position by the first limiting member 61, so that the washing machine can be kept in the set operation mode (for example, in the double-drive washing mode).

In the process that the first moving member 2 moves from the first position to the second position, the second limiting member 62 moves to avoid the first moving member 2, so that the first moving member 2 can smoothly move along the first direction in the process that the power unit 200 drives the third moving member 4 to move to drive the first moving member 2 to move along the first direction, and the second limiting member 62 is prevented from obstructing the first moving member 2. When the first moving member 2 is located at the second position, for example, when the power unit 200 drives the third moving member 4 to move to drive the first moving member 2 to move to the second position along the first direction, the power unit 200 is powered off, or when the power unit 200 drives the third moving member 4 to drive the first moving member 2 to move between the second position and the final position (for example, between the final position and the second position) along the first direction, the power unit 200 is powered off, and when the first moving member 2 moves reversely to the second position, the second limiting member 62 cooperates with the first moving member 2 to limit the first moving member 2 at the second position, so that when the power unit 200 is powered off, the first moving member 2 can be kept at the second position by the second limiting member 62, so that the washing machine can be kept operating in the set operating mode (for example, operating in the new water flow washing mode).

When the first moving member 2 is located at the first position, the first moving member 2 and the first limiting member 61 are abutted against each other in the first direction so as to limit the first moving member 2 at the first position, so that when the power unit 200 is powered off, the first moving member 2 can be conveniently limited in the first direction by the first limiting member 61, and the first moving member 2 is prevented from moving reversely, so that the first moving member 2 is kept at the first position. When the first moving member 2 is located at the second position, the first moving member 2 and the second limiting member 62 abut against each other in the first direction so as to limit the first moving member 2 at the second position, so that when the power unit 200 is powered off, the first moving member 2 can be conveniently limited in the first direction by the second limiting member 62, and the first moving member 2 is prevented from moving reversely, so that the first moving member 2 is kept at the second position.

In the process that the first moving member 2 moves from the initial position to the first position, the first moving member 2 can press the first limiting member 61, at this time, the first elastic member 73 is compressed, the first limiting member 61 moves in a direction away from the first moving member 2 to avoid the first moving member 2, so that the first moving member 2 can smoothly move to the first position, when the first moving member 2 moves to the first position, the first moving member 2 does not press the first limiting member 61 any more, the first elastic member 73 stretches to drive the first limiting member 61 to move in a direction adjacent to the first moving member 2, and when the power unit 200 is powered off, the first moving member 2 can be limited to the first position by the blocking effect of the first limiting member 61, and the first moving member 2 is prevented from moving reversely beyond the first position.

During the process that the first moving member 2 moves from the first position to the second position, the first moving member 2 can press the second limiting member 62, at this time, the second elastic member 74 is compressed, the second limiting member 62 moves towards the direction away from the first moving member 2 to avoid the first moving member 2, so that the first moving member 2 can smoothly move to the second position, when the first moving member 2 moves to the second position, the first moving member 2 does not press the second limiting member 62 any more, the second elastic member 74 stretches to drive the second limiting member 62 to move towards the direction adjacent to the first moving member 2, and when the power unit 200 is powered off, the first moving member 2 can be limited to the second position by the blocking effect of the second limiting member 62, so that the first moving member 2 is prevented from moving reversely beyond the second position.

When the transmission mechanism 100 needs to be reset, since the first limiting piece 61 or the first limiting piece 61 and the second limiting piece 62 form an obstruction to the reverse movement of the first moving piece 2, the driving piece 72 can be driven to move in a direction away from the first moving piece 2 through the power piece 71 at this time, so that the first limiting piece 61 and the second limiting piece 62 are driven to move in a direction away from the first moving piece 2, and the driving piece 72 can be driven to move in a direction adjacent to the first moving piece 2 after the first moving piece 2 is reset to realize the reset when the first limiting piece 61 and the second limiting piece 62 do not form an obstruction to the reverse movement of the first moving piece 2.

For example, when the power member 71 is an electromagnetic retractor, after the first moving member 2 is reset, the power member 71 is powered off, and since the power member 71 is an electromagnetic retractor, the electromagnetic retractor itself has a reset function, and the driving block 72 can move to reset toward a direction adjacent to the first moving member 2 under the action of a reset spring in the electromagnetic retractor.

The working process of the transmission mechanism 100 is described below by using the power unit 200 as a 45mm single-stroke tractor, wherein the first stroke, the second stroke and the third stroke are all 15mm, the distance between the end position and the second position can be 1mm, and the distance between the driving position and the end position is 1mm. The first stopper 61 is located at a first position, the second stopper 62 is located at a second position, the first trigger 81a is located between the first position and the second position and adjacent to the first position, and the second trigger 81b is located between the second position and the end position.

Referring to fig. 2 to 5, when it is required to put the washing machine in the normal washing mode, the power unit 200 is not operated, the third moving member 4 is at the initial position, and the third moving member 4 is not moved, so that the first moving member 2 and the second moving member 3 are not moved, and thus, the clutch lever (first operation member 301) of the clutch assembly (first execution unit 300) and the valve core (second operation member) of the drain valve (second execution unit 400) are not moved, at this time, the drain valve is closed and the clutch lever is at the initial control angle, and when the clutch brake is tightened and the wrap spring is released, the pulsator and the inner tub 500 are separated and the inner tub 500 is locked, and only the pulsator is rotated, thereby achieving normal washing.

Referring to fig. 6 and 7, when the washing machine needs to be switched from the normal washing mode to the double-drive washing mode, the power unit 200 is energized to drive the third moving member 4 to move, because the second driving part 433 and the first driving part 212 are matched, the third moving member 4 can drive the first moving member 2 to move along the first direction, and because in the process, although one side of the first moving member 2 far away from the third moving member 4 is abutted with the limiting block 5, at the same time, one side of the first moving member 2 far away from the third moving member 4 is abutted with the side wall of the first chute 111 in the second direction, so that the rigid limit of the first moving member 2 in the second direction can be realized, while the first driving part 212 and the second driving part 433 are in inclined plane matching, the first moving member 2 only moves along the first direction and does not move along the second direction.

When the first moving member 2 moves to contact with the first limiting member 61, the first moving member 2 may press the first limiting member 61 in the process of continuing to move forward, and the first elastic member 73 is compressed, so that the first limiting member 61 may avoid the first moving member 2, and the first moving member 2 may move smoothly in the first direction. After the first moving member 2 passes the first position, the first stopper 61 is no longer subjected to the pressing force of the first moving member 2, and the first elastic member 73 is stretched to drive the first stopper 61 to return.

When the first moving member 2 moves to contact the first triggering member 81a, in the process that the first moving member 2 continues to move forward, the first moving member 2 pushes the first triggering member 81a to move towards the direction adjacent to the first conducting plate 81, and the first triggering member 81a can contact and push the first conducting plate 81 to be separated from the second conducting plate 82 through movement, and at the moment, the electric control board receives a corresponding signal to control the power unit 200 to be powered off. Under the action of the first control 301, the first moving element 2 moves reversely to the first position, and due to the cooperation of the first driving part 212 and the second driving part 433, the third moving element 4 moves reversely to the first position along with the first moving element 2, and the first limiting element 61 located at the first position can form a blocking effect on the first moving element 2, so that the first moving element 2 cannot move continuously, and therefore the first moving element 2 can be limited at the first position, and meanwhile, the third moving element 4 is limited at the first position.

The power unit 200 may be kept powered off for a predetermined time, so that the first mover 2 may be kept at the first position for a predetermined time. In this process, since the fourth driving part 44 and the third driving part 32 are in the disengaged state and the second moving member 3 is connected to the second operating member, the second moving member 3 is not moved and the drain valve is closed. The clutch driving lever rotates to a first control angle, the clutch brake is released and the holding spring is released, the inner barrel 500 is in a free state, and when the pulsator rotates, the washing water in the inner barrel 500 is driven to move, so that the inner barrel 500 can be driven to reversely rotate, and the hand rubbing washing effect can be realized.

Referring to fig. 8 and 9, when the washing machine is switched from the dual-drive washing mode to the new water-flow washing mode, the power unit 200 is energized to operate, so as to continuously drive the third moving member 4 to move, because the second driving part 433 and the first driving part 212 are matched, the third moving member 4 can drive the first moving member 2 to move to the second position along the first direction, and because in the process, although one side of the first moving member 2 far away from the third moving member 4 is abutted with the limiting block 5, at the same time, one side of the first moving member 2 far away from the third moving member 4 is abutted with the side wall of the first chute 111 in the second direction, so that the rigid limit of the first moving member 2 in the second direction can be realized, and although the first driving part 212 and the second driving part 433 are in inclined plane matching, at the moment, the first moving member 2 only moves along the first direction but does not move in the second direction.

When the first moving member 2 moves to contact with the second limiting member 62, the first moving member 2 can press the second limiting member 62 in the process of continuing to move forward, and the second elastic member 74 is compressed, so that the second limiting member 62 can avoid the first moving member 2, and the first moving member 2 can move smoothly along the first direction. After the first moving member 2 passes the second position, the second limiting member 62 is no longer pressed by the first moving member 2, and the second elastic member 74 stretches to drive the second limiting member 62 to return.

When the first moving member 2 moves to contact the second triggering member 81b, in the process that the first moving member 2 continues to move forward, the first moving member 2 pushes the second triggering member 81b to move towards the direction adjacent to the third conducting plate 83, and the second triggering member 81b can contact and push the third conducting plate 83 to be separated from the fourth conducting plate 84 through movement, and at the moment, the electric control board receives a corresponding signal to control the power unit 200 to be powered off. Under the action of the first control 301, the first moving element 2 moves reversely to the second position, and due to the cooperation of the first driving part 212 and the second driving part 433, the third moving element 4 moves reversely to the second position along with the first moving element 2, and the first limiting element 61 located at the second position can form a blocking effect on the first moving element 2, so that the first moving element 2 cannot move reversely, and therefore the first moving element 2 can be limited to the second position, and meanwhile, the third moving element 4 is limited to the second position.

The power unit 200 may be kept powered off for a predetermined time, so that the first mover 2 may be kept at the second position for a predetermined time. In the process, the second moving part 3 is not moved, when the clutch brake is released and the spring is held tightly, the impeller rotates to drive the inner barrel 500 to synchronously rotate, so that tornado water flow can be realized, the water flow impact force in the inner barrel 500 is large, water in the inner barrel 500 can climb upwards along the inner wall of the inner barrel 500 under the action of centrifugal force, and a better scouring and washing effect is achieved.

Referring to fig. 10 and 11, when the washing machine is switched from the new water washing mode to the dewatering mode, the power unit 200 is energized to continuously drive the third moving member 4 to move, and when the third moving member 4 moves to the final position by 1mm, the third moving member 4 drives the first moving member 2 to move to the final position in the first direction due to the fact that the second driving part 433 and the first driving part 212 still cooperate, and when the first moving member 2 moves in the second direction due to the fact that the side, away from the third moving member 4, of the first moving member 2 is abutted with the limiting block 5, the side, away from the third moving member 4, of the first moving member 2 is abutted with the side wall, in the second direction, of the first chute 111 at the same time, so that rigid limiting of the first moving member 2 in the second direction can be achieved, and when the first driving part 212 and the second driving part 433 cooperate in an inclined plane, the first moving member 2 moves only in the first direction but does not move in the second direction.

When the third moving member 4 drives the first moving member 2 to move to the final position, the second limiting surface 214 on the first moving member 2 is matched with the first limiting portion 1131 on the mounting seat 1, and in the subsequent moving process of the third moving member 4, since the first moving member 2 is limited by the first limiting portion 1131, the first moving member 2 does not move along the first direction along with the third moving member 4. In the process of moving the third moving member 4 from the end position to the end position, the first driving portion 212 and the second driving portion 433 are disengaged, and the third moving member 4 presses the first moving member 2 toward the direction adjacent to the stopper 5, the first moving member 2 moves toward the direction adjacent to the stopper 5 in the second direction and presses the stopper 5, the elastic driving member 53 is compressed, and the third stopper surface 215 of the first moving member 2 is engaged with the second stopper portion 1132, so that the first moving member 2 can be stopped in the first direction, and at the same time, since the first moving member 2 is stopped by the stopper 5 and the third moving member 4 in the second direction, positioning of the first moving member 2 at the end position can be achieved. When the third moving member 4 moves to the driving position, the fourth driving part 44 is matched with the third driving part 32, and in the process that the third moving member 4 moves from the driving position to the final position, the third moving member 4 drives the second moving member 3 to move, and the power unit 200 can keep energized according to the preset time, so that the third moving member 4 is kept at the final position, namely the second moving member 3 is kept at the position, the first moving member 2 is not moved in the process, and when the clutch brake is released and the spring is held tightly, the wave wheel rotates to drive the inner barrel 500 to synchronously rotate, thereby dewatering and drainage can be realized.

After the dewatering and drainage mode is completed, the transmission mechanism 100 needs to be reset, and the driving piece 71 drives the driving piece 72 to move in a direction away from the first moving piece 2, so that the first limiting piece 61 and the second limiting piece 62 do not form a block for the first moving piece 2 in the first direction. After the driving block 72 is driven by the power piece 71 to move a set distance in a direction away from the first moving piece 2, the power unit 200 stops working, the second elastic reset piece drives the second control piece to reset, so that the second moving piece 3 is driven to move reversely, the third moving piece 4 is driven to move reversely in the process of moving reversely by the second moving piece 3, when the third moving piece 4 moves reversely by 14mm to a final position, the extrusion force of the third moving piece 4 on the first moving piece 2 in the second direction is reduced, the elastic driving piece 53 stretches and drives the limiting block 5 to move in a direction adjacent to the first moving piece 2, so that the first moving piece 2 is driven to move in a direction adjacent to the third moving piece 4, and reset of the first moving piece 2 in the second direction is realized, at this time, the second driving part 433 of the third moving piece 4 is in restoration fit with the first driving part 212 of the first moving piece 2, the second limiting surface 214 of the first moving piece 2 is out of fit with the first limiting part 1131, and the third limiting surface 215 of the first moving piece 2 is out of fit with the second limiting part 1132, so that the first moving piece 2 can move in the first direction. At this time, the first elastic reset element drives the first control element 301 to reset, so as to drive the first moving element 2 to move reversely and reset to the initial position, and meanwhile, the first moving element 2 can drive the third moving element 4 to move reversely and reset to the initial position together.

The power member 71 remains energized during the return of the first 2, second 3 and third 4 moving members so that the first 61 and second 62 stop members remain free from blocking the first moving member 2 in the first direction during the return. After the first moving member 2, the second moving member 3 and the third moving member 4 are reset, the power member 71 is powered off, and the self-contained reset spring of the power member 71 can drive the driving block 72 to reset, so that the first limiting member 61 and the second limiting member 62 are reset, and the reset of the transmission mechanism 100 can be realized.
