In some embodiments of the present invention, the power unit 200 is adapted to drive the third moving element 4 to move along the first direction, a starting position of a stroke of the third moving element 4 in the first direction is an initial position, a final position of the stroke of the third moving element 4 in the first direction is an end position, and the initial position, the first position, the second position and the end position are sequentially arranged at intervals in the first direction. In the process that the third moving part 4 moves from the initial position to the final position along the first direction, the third moving part 4 drives the first moving part 2 to move to the final position along the first direction, and the first moving part 2 is kept at the final position; in the process that the third moving member 4 moves from the end position to the end position along the first direction, the third moving member 4 drives the second moving member 3 to move to the preset position. Because the first moving part 2 moves to the end position and is kept at the end position, in the process that the third moving part 4 moves from the end position to the end position along the first direction, the third moving part 4 does not drive the first moving part 2 to move any more, the first moving part 2 does not move in the first direction and is kept at the end position, and the third moving part 4 drives the second moving part 3 to move to the preset position, so that the third moving part 4 can drive one of the first moving part 2 and the second moving part 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 may drive the first moving member 2 to move synchronously, and since the first moving member 2 drives the first manipulating member 301 to move when moving, the working state of the first executing unit 300 may be adjusted, and further, the working mode of the household appliance may be adjusted, and the third moving member 4 may be stopped and maintained at a certain set position between the initial position and the end position or the third moving member 4 may be stopped and maintained at the end position as required, and when the third moving member 4 stops and is maintained at a different position, the first moving member 2 also stops and is maintained at a corresponding position along with the third moving member 4. The third moving member 3 is at the initial position, at a position between the initial position and the end position, or at the end position, and the first actuator 300 has different operation states at different positions of the first moving member 2 as the third moving member 3 is at the initial position, at a position between the initial position and the end position, or at the end position, so that the operation mode of the home appliance can be further enriched.

The stroke of the third moving element 4 in the first direction may include a first stroke, a second stroke, and a third stroke, and the third moving element 4 may move the first stroke to the end of the first stroke, the first stroke and the second stroke to the end of the second stroke, and the first stroke, the second stroke, and the third stroke to the end of the third stroke at one time under the driving of the power unit 200. The third moving element 4 may be driven by the power unit 200 to move to the end of the first stroke and maintain the position for a predetermined time, and then move to the end of the second stroke and maintain the position for a predetermined time. Alternatively, the third moving element 4 may be driven by the power unit 200 to move the first stroke to the end of the first stroke and keep the first stroke at the position for a predetermined time, then move the second stroke to the end of the second stroke and keep the second stroke at the position for a predetermined time, and finally move the third stroke to the end of the third stroke and keep the third stroke at the position for a predetermined time. Alternatively, the third moving member 4 may be driven by the power unit 200 to move the first stroke and the second stroke to the end of the second stroke and keep them at the position for a predetermined time, and then move the third stroke to the end of the third stroke and keep them at the position for a predetermined time.

In some embodiments, power unit 200 may be a three-stroke tractor. Thereby, the third mover 4 can be moved in the first direction by three strokes and can be held at each end-of-stroke position for a predetermined time. For example, the power unit 200 may be a 45mm three-stroke tractor, and the first, second, and third strokes may be 15mm, and 15mm, respectively. Wherein, a traction groove 42 can be formed on the third moving member 4, the power unit 200 can be connected with the third moving member 4 through a traction rope 201, and a rope end of the traction rope 201 can be buckled on the traction groove 42, so as to realize the connection of the power unit 200 and the third moving member 4.

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, which are sequentially spaced in the first direction, and the initial position, the first position, the second position and the end position are a first stroke, a second stroke and a third stroke respectively. The first mover 2 has an end position in the first direction, the end position being located at the second position or the end position being located between the second position and the end position and being adjacent to the second position. In the process that the power unit 200 drives the third moving element 4 to move from the second position to the end position, the third moving element 4 drives the first moving element 2 to move to the end position along the first direction, and the second moving element 3 is not moved.

When the third moving member 4 drives the first moving member 2 to move to the first position, the third moving member 4 may stop and be kept at the first position, so that the first moving member 2 stops and is kept at the first position along with the third moving member 4, and at this time, 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 household appliance may be adjusted.

When the third moving member 4 drives the first moving member 2 to move to the second position, the third moving member 4 may stop and be kept at the second position, so that the first moving member 2 is kept at the second position along with the stop of the third moving member 4, and at this time, the first moving member 2 drives the first control member 301 to move to the second control angle, so that the working state of the first execution unit 300 is further changed, and the working mode of the household appliance may be further adjusted. Therefore, when the third moving part 4 drives the first moving part 2 to move to different positions, the household appliance can be adjusted to different working modes, the working modes of the household appliance are richer, and the switching between the different working modes is convenient.

Further, the third moving member 4 has a driving position in the first direction for starting to drive the second moving member 3 to move, and the driving position is located at the end position or between the end position and is 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 to be stationary, so that the working state of the first execution unit 300 can be adjusted, and the working state of the second execution unit 400 remains unchanged, thereby adjusting the working mode of the household appliance; 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 fixed and kept at the end position, 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 household appliance.

When it is determined that the driving position is between the end position and is adjacent to the end position, the first moving member 2 and the second moving member 3 are not moved in the first direction in the process of moving the third moving member 4 from the end position to the driving position, in 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. For example, when the third mover 4 moves from the end position to the driving position, the third mover 4 presses the first mover 2 in the second direction to move the first mover 2 by a set distance in the second direction, the first mover 2 is immovable after moving the set distance in the second direction and is maintained at the end position in the first direction, and the second mover 3 is immovable.

When the termination position is located between the second position and the end position and is adjacent to the second position, the size error and the assembly error of the part can be allowed to exist in a certain range, the processing difficulty is reduced, and the influence on the accuracy of the stroke due to the size error and the assembly error can be avoided, so that the working accuracy of the transmission mechanism 100 is influenced. Optionally, when the end position is located between and adjacent to the second position, the distance between the end position and the second position in the first direction is in the range of 0.8-1.5mm, for example the distance between the end position and the second position may be 1 mm. By setting the distance between the end position and the second position to between 0.8 and 1.5mm, it is possible to meet both machining and assembly tolerances, without affecting the working condition of the first actuator, i.e. the working condition of the first actuator is the same when the first moving member 2 is in the second position and the end position.

In some embodiments, when the driving position is located between the end position and is adjacent to the end position, the dimensional error and the assembly error of the component can be allowed to exist in a certain range, the processing difficulty is reduced, and the influence on the precision of the stroke due to the existence of the dimensional error and the assembly error, and the working accuracy of the transmission mechanism 100 can be avoided. Optionally, when the driving position is located between and adjacent to the end position, the distance between the driving position and the end position in the first direction is in the range of 0.8-1.5mm, for example the distance between the driving position and the end position may be 1 mm. By setting the distance between the driving position and the terminating position to be between 0.8 mm and 1.5mm, the processing and assembling errors can be met, and the third moving part 4 is not influenced to drive the second moving part 3 to move enough distance to enable the second execution unit 400 to change the working state.

For example, the first execution unit 300 may have a first operation state, a second operation state, and a third operation state, and the second execution unit 400 may have a first state and a second state. When the third moving member 4 is at the initial position, the power unit 200 is not operated, and the first actuator 300 is in the first operating state and the second actuator 400 is in the first state, and the household appliance can be in the first operating mode (refer to fig. 2-5); when the power unit 200 is operated to drive the third moving element 4 to move to the first position, the operating state of the first executing unit 300 is changed to the second operating state, in the process, the second moving element 3 is not moved, the operating state of the second executing unit 400 is maintained in the first state, and the household appliance can be in the second operating mode (refer to fig. 6 and 7); when the power unit 200 is operated to drive the third moving element 4 to move to the second position, the operating state of the first executing unit 300 is further changed to a third operating state, in the process, the second moving element 3 does not move, the operating state of the second executing unit 400 is maintained in the first state, and the household appliance can be in a third operating mode (refer to fig. 8 and 9); the power unit 200 operates to drive the third moving element 4 to move to the end position, in the process, the third moving element 4 drives the first moving element 2 to move to the end position, the first moving element 2 can be kept at the end position in the first direction, in the process that the third moving element 4 moves from the driving position to the end position, the third moving element 4 drives the second moving element 3 to move, at this time, the working state of the first execution unit 300 is kept at the third working state, the working state of the second execution unit 400 is changed to the second state, at this time, the household appliance can be in the fourth working mode (refer to fig. 10 and 11).

Optionally, the first executing element includes a first elastic resetting element for resetting the first manipulating element 301, and when the first manipulating element 301 is reset, the first executing element drives the first moving element 2 to reset, so that the first moving element 2 can be reset to the initial position; the second executing part comprises a second elastic resetting part for resetting the second control part, and the second elastic resetting part drives the second moving part 3 to reset when the second control part resets; the third moving member 4 is reset by at least one of the first moving member 2 and the second moving member 3. Thereby, the reset of the entire transmission mechanism 100 can be achieved.

For example, in the second operation mode of the household electrical appliance, if the transmission mechanism 100 is to be reset, the power unit 200 may not operate, the first elastic resetting 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 at the same time, the first moving member 2 may drive the third moving member 4 to move reversely and reset to the initial position, so as to reset the transmission mechanism 100.

For another example, when the household electrical appliance is in the third operating mode, if the transmission mechanism 100 is to be reset, the power unit 200 may not operate, the first elastic resetting 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 may drive the third moving member 4 to move reversely and reset to the initial position, so as to reset the transmission mechanism 100.

For another example, in the fourth operation mode of the household electrical appliance, if the transmission mechanism 100 is to be reset, the power unit 200 may not operate, the second elastic resetting member drives the second operating member to reset, so as to drive the second moving member 3 to move reversely to reset, and in the process of moving reversely the second moving member 3, the third moving member 4 is driven to move reversely, and when the third moving member 4 moves reversely to the end position, the first elastic resetting member may drive the first operating member 301 to reset, so as to drive the first moving member 2 to move reversely and reset to the initial position, and at the same time, the first moving member 2 may drive the third moving member 4 to move reversely and reset to the initial position, so as to reset the transmission mechanism 100.

Specifically, referring to fig. 19 to 20 in combination with fig. 2 to 11, the third moving member 4 has a retaining protrusion 41, the retaining protrusion 41 is located on a side of the first moving member 2 adjacent to the power unit 200 in the first direction, and the retaining protrusion 41 is adapted to abut against the first moving member 2, for example, a portion of a side wall of the third moving member 4 adjacent to the power unit 200 in the first direction may constitute a first limiting surface 213 adapted to abut against the retaining protrusion 41. For example, between the initial position and the end position, the retaining projection 41 may abut the first mover 2; between the end position and the end position, the escape prevention projection 41 can be separated from the first mover 2. From this, when third motion 4 is located the terminal position, if drive mechanism 100 needs to reset, reverse movement under the drive of second motion 3 is moved to third motion 4, when the anticreep of third motion 4 is protruding 41 and first motion 2 butt, can play the limiting displacement to third motion 4, prevents that the effect of second elasticity resets that the reverse movement of third motion 4 is too much and influence drive mechanism 100's normal reset.

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

In this embodiment, the operation modes of the household appliance may include a normal washing mode, a dual-drive washing mode, a new water flow washing mode and a drainage mode, wherein the normal washing mode is the first operation mode, the dual-drive washing mode is the second operation mode, the new water flow washing mode is the third operation mode, and the drainage mode is the fourth operation mode. The home appliance includes a cabinet, an inner tub 500 rotatably provided in the cabinet, a pulsator rotatably provided in the inner tub 500, a first actuator 300, a second actuator 400 and a driving mechanism 100 all provided in the cabinet, the first actuator 300 being connected to the inner tub 500 and the pulsator, and the second actuator 400 being openable and closable to discharge washing water.

The first execution unit 300 may be a clutch assembly, and the first manipulation member 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 locking spring for controlling a clutch relationship between the pulsator and the inner tub 500. When the clutch brake is released, the inner tub 500 is in a free state, and when the pulsator rotates, the pulsator disturbs the movement of water flow in the inner tub 500, thereby driving the inner tub 500 to rotate reversely; when the clutch is braked and tightened, the inner barrel 500 is locked and can not drive the inner barrel 500 to rotate when the impeller rotates. When the holding spring is loosened, the impeller is separated from the inner barrel 500, and the impeller cannot drive the inner barrel 500 to rotate when rotating; when the clasping springs are clasped, 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 is released and the holding spring is released, the inner tub 500 is in a free state, and when the pulsator rotates, the washing water in the inner tub 500 is driven to move, so that the inner tub 500 can be driven to rotate reversely; when the brake of the clutch is released and the holding spring is tightly held, the impeller rotates to drive the inner barrel 500 to synchronously rotate; when the clutch brake is tightly braked and the holding spring is loosened, the inner barrel 500 is separated from the impeller, the inner barrel 500 is locked and is not moved, and only the impeller rotates at the moment.

The second execution unit 400 may be a drain valve, the second manipulation member may be a valve core of the drain valve, and the change of the state of the second execution unit 400 is achieved by the movement of the second manipulation member, the second execution unit 400 has an open state and a closed state, when the second execution unit 400 is in the open state (i.e., the second state), the inner tub 500 may discharge the washing water, and when the second execution unit 400 is in the closed state (i.e., the first state), the washing water in the inner tub 500 may not be discharged through the drain valve.

Referring to fig. 2 to 5, when the household appliance needs to be in the normal washing mode, the power unit 200 does not operate, the third moving element 4 is in the initial position, and the third moving element 4 does not move, so the first moving element 2 and the second moving element 3 do not move, and further the clutch lever (the first manipulating element 301) of the clutch assembly (the first executing unit 300) and the valve spool (the second manipulating element) of the drain valve (the second executing unit 400) do not move, at this time, the drain valve is closed, and the clutch lever is in the initial control angle, when the clutch brake is tightened, and the clasping spring is loosened, the pulsator and the inner tub 500 are separated, the inner tub 500 is locked, only the pulsator rotates, and normal washing is achieved.

Referring to fig. 6 and 7, when it is required to put the household appliance in the dual-drive washing mode, the power unit 200 is operated to drive the third moving member 4 to move to the end of the first stroke (i.e., the first position), and drive the first moving member 2 to synchronously move to the first position and to be maintained at the first position according to a predetermined time, during which the second moving member 3 is not moved and the drain valve is closed. The clutch lever rotates to a first control angle, the clutch brake is released and the holding spring is released, the inner tub 500 is in a free state, and when the pulsator rotates, the washing water in the inner tub 500 is driven to move, so that the inner tub 500 can be driven to rotate reversely, and the hand-rubbing washing effect can be realized.

Referring to fig. 8 and 9, when the household appliance needs to be in a new water flow washing mode, the power unit 200 operates to drive the third moving element 4 to move to the end of the second stroke (i.e., the second position), and drive the first moving element 2 to synchronously move to the second position and to be kept at the second position according to a predetermined time, during which the second moving element 3 is not moved, the clutch brake is released and the holding spring is clasped, the pulsator rotates to drive the inner tub 500 to synchronously rotate, so that a tornado water flow can be realized, the water flow impact force in the inner tub 500 is large, and the water in the inner tub 500 can climb upwards along the inner wall of the inner tub 500 under the action of centrifugal force, thereby achieving a better washing effect.

Referring to fig. 10 and 11, when the household appliance needs to be in the drainage mode, the power unit 200 operates to drive the third moving member 4 to move to the end of the third stroke (i.e., the end position) and drive the second moving member 3 to move, the third moving member 4 moves to the end position and can be kept at the end position according to a predetermined time, the first moving member 2 is not moved (the end position is at the second position) in the process, or the first moving member 2 moves together with the third moving member 4 in the process of moving from the second position to the end position and the first moving member 2 is limited at the end position and is fixed in the process of moving from the end position to the end position, and when the clutch brake is released and the holding spring is held tightly, the pulsator rotates to drive the inner tub 500 to rotate synchronously, so that drainage can be achieved.

When the household appliance is used for washing clothes, any one of a normal washing mode, a double-drive washing mode and a new water flow washing mode can be executed according to the selection of a user, and multiple washing modes (at least two of the normal washing mode, the double-drive washing mode and the new water flow washing mode) can also be executed. The washing mode of the household appliance can be input by a user through the control panel, or can be a washing mode written in an electric control board of a control device of the household appliance in advance.

The program for the home appliance to treat the laundry may include, but is not limited to, the following several cases.

The method comprises the following steps of firstly, a common washing mode, a double-drive washing mode, a new water flow washing mode and a dewatering and draining mode: the power unit 200 is not operated so that the third moving member 4 is maintained at the initial position for a predetermined time, at which the home appliance is operated in the general washing mode for a predetermined time; the power unit 200 is operated to drive the third moving member 4 to move to the first position and maintain the third moving member 4 at the first position for a predetermined time, at which time the home appliance operates for the predetermined time in the dual drive washing mode; the power unit 200 is operated to drive the third moving member 4 to move to the second position and to maintain the third moving member 4 at the second position for a predetermined time, at which time the home appliance operates in the new water washing mode for a predetermined time; the power unit 200 is operated to drive the third moving member 4 to move to the end position and to maintain the third moving member 4 at the end position for a predetermined time, at which the home appliance is operated in the drainage mode for a predetermined time.

Case four, the double-drive washing mode + the new water flow washing mode + the dewatering and draining mode: the power unit 200 is operated to drive the third moving member 4 to move to the first position and maintain the third moving member 4 at the first position for a predetermined time, at which time the home appliance operates for the predetermined time in the dual drive washing mode; the power unit 200 is operated to drive the third moving member 4 to move to the second position and to maintain the third moving member 4 at the second position for a predetermined time, at which time the home appliance operates in the new water washing mode for a predetermined time; the power unit 200 is operated to drive the third moving member 4 to move to the end position and to maintain the third moving member 4 at the end position for a predetermined time, at which the home appliance is operated in the drainage mode for a predetermined time.

Alternatively, the washing force of the normal washing mode, the dual driving washing mode and the new water flow washing mode is sequentially increased, and when the home appliance performs a plurality of washing modes, a washing mode having a low washing force may be preferentially performed. For example, when the household appliance includes the two washing modes, the washing mode with lower washing force may be executed first, and then the washing mode with higher washing force may be executed; when the household appliance comprises the three washing modes, the washing mode with the lowest washing force can be executed firstly, then the washing mode with the higher washing force is executed, and finally the washing mode with the highest washing force is executed. Therefore, the power unit 200 does not need to be powered on or off frequently, and the third moving part 4 can move along the first direction according to the sequence of the stroke sections, so that the control of the whole machine is simpler and is not easy to make mistakes.

In other embodiments, when the household appliance performs a plurality of washing modes, the washing mode with high washing force may be performed first.

In other embodiments, when the household appliance performs multiple washing modes, the multiple washing modes can be switched back and forth.

According to the transmission mechanism 100 of the household appliance, the driving action of the power unit 200 can be distributed, so that one of the first moving part 2 and the second moving part 3 can be driven to move by the movement of the third moving part 4 at a specific position and time, so that the household appliance has more 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 household appliance can be conveniently realized, more washing requirements of a user can be met, the overall structure of the household appliance can be simplified, and the operation cost can be reduced.

From this, through set up on mount pad 1 and be used for carrying out spacing limit structure to first motion 2 in the first direction, when first motion 2 moved to the termination point, through first motion 2 and limit structure's cooperation, can be spacing at the termination point with first motion 2 to can guarantee to move the in-process to the final position at third motion 4 from the termination point, third motion 4 can not drive first motion 2 again and move in the first direction. When the third moving member 4 is located at the end position, if the transmission mechanism 100 needs to be reset, when the third moving member 4 moves reversely to the end position, the first moving member 2 may be disengaged from the limiting structure, so that the first moving member 2 may be unlocked in the first direction, and the first moving member 2 may be driven by the first manipulating member 301 to move reversely to reset.

According to some embodiments of the present invention, referring to fig. 2-15, 18 and 20, the first mover 2 has a first driving portion 212, and the third mover 4 has a second driving portion 433 adapted to cooperate with the first driving portion 212.

In addition, when the transmission mechanism 100 is reset, the first moving part 2 is driven by the first control part 301 to move reversely for resetting, and through the cooperation of the first driving part 212 and the second driving part 433, the third moving part 4 can be driven by the first moving part 2 to move reversely for resetting.

The operation of the transmission mechanism 100 will be described below with reference to the power unit 200 being a 45mm three-stroke tractor, where the first stroke, the second stroke and the third stroke are all 15mm, the distance between the end position and the second position in the first direction may be 1mm, and the distance between the driving position and the end position may be 1 mm.

Referring to fig. 2 to 5, when the household appliance needs to be in the normal washing mode, the power unit 200 does not operate, the third moving element 4 is in the initial position, and the third moving element 4 does not move, so the first moving element 2 and the second moving element 3 do not move, and further the clutch lever (the first manipulating element 301) of the clutch assembly (the first executing unit 300) and the valve spool (the second manipulating element) of the drain valve (the second executing unit 400) do not move, at this time, the drain valve is closed, and the clutch lever is in the initial control angle, and when the clutch brake is tightened and the holding spring is loosened, the inner tub 500 is locked, and only the pulsator rotates, thereby achieving normal washing.

Referring to fig. 6 and 7, when the home appliance needs to be switched from the normal washing mode to the dual drive washing mode, the power unit 200 is operated to drive the third moving member 4 to move 15mm to the end of the first stroke (i.e. the first position), since the second driving portion 433 and the first driving portion 212 are engaged, the third moving member 4 can move the first moving member 2 to the first position along the first direction, and since in the process, although the side of the first moving member 2 away from the third moving member 4 is also abutted against the limit block 5, at the same time, the side of the first moving member 2 away from the third moving member 4 is also abutted against the side wall of the first sliding groove 111 in the second direction, so that the rigid limit of the first moving member 2 in the second direction can be realized, although the first driving part 212 and the second driving part 433 are slope-fitted, the first mover 2 is moved only in the first direction and not in the second direction at this time. The third moving part 4 drives the first moving part 2 to move to the first position synchronously and can be kept at the first position according to the preset time, in the process, because the fourth driving part 44 and the third driving part 32 are in a disengaged state and the second moving part 3 is connected with the second control part, the second moving part 3 is not moved, and the drain valve is closed. The clutch lever rotates to a first control angle, the clutch brake is released and the holding spring is released, the inner tub 500 is in a free state, and when the pulsator rotates, the washing water in the inner tub 500 is driven to move, so that the inner tub 500 can be driven to rotate reversely, and the hand-rubbing washing effect can be realized.

Referring to fig. 8 and 9, when the household appliance is switched from the dual-drive washing mode to the new water flow washing mode, the power unit 200 operates to drive the third moving element 4 to move continuously, the third moving element 4 moves 15mm to the end of the second stroke (i.e. the second position), because the second driving portion 433 is engaged with the first driving portion 212, the third moving element 4 can drive the first moving element 2 to move to the second position along the first direction, and because in the process, although the side of the first moving element 2 far from the third moving element 4 is also abutted with the limiting block 5, the side of the first moving element 2 far from the third moving element 4 is also abutted with the side wall of the first sliding groove 111 in the second direction, so that the rigid limit of the first moving element 2 in the second direction can be realized, although the first driving portion 212 and the second driving portion 433 are engaged in a slope, at this time, the first mover 2 moves only in the first direction and does not move in the second direction. The third motion part 4 drives the first motion part 2 to move to the second position synchronously and can keep the second position according to the scheduled time, in the process, because the fourth driving part 44 and the third driving part 32 are in the disengaged state and the second motion part 3 is connected with the second control part, the second motion part 3 still does not move, the drain valve is closed, when the clutch brake is released and the holding spring is held tightly, the impeller rotates to drive the inner barrel 500 to rotate synchronously, thus the tornado water flow can be realized, the water flow impact force in the inner barrel 500 is large, and the water in the inner barrel 500 can climb upwards along the inner wall of the inner barrel 500 under the action of the centrifugal force, and the washing effect is better.

Referring to fig. 10 and 11, when the home appliance is switched from the fresh water washing mode to the draining mode, the power unit 200 is operated, continues to drive the third mover 4 to move, when the third mover 4 moves 1mm to the end position, in the process, since the second driving part 433 and the first driving part 212 are still engaged, it is possible to cause the third movement element 4 to bring the first movement element 2 along the first direction to the end position, and since in the process, although the side of the first moving member 2 away from the third moving member 4 is also abutted against the limit block 5, at the same time, the side of the first moving member 2 away from the third moving member 4 is also abutted against the side wall of the first sliding groove 111 in the second direction, so that the rigid limit of the first moving member 2 in the second direction can be realized, although the first driving part 212 and the second driving part 433 are slope-fitted, the first mover 2 is moved only in the first direction and not in the second direction at this time.

When the third moving member 4 drives the first moving member 2 to move to the end 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, because 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 with the third moving member 4. In the process that the third moving member 4 moves from the end position to the end position, the first driving portion 212 and the second driving portion 433 are disengaged, and the first moving member 2 presses the first moving member 2 toward the direction adjacent to the stopper 5, the first moving member 2 moves in the second direction toward the direction adjacent to the stopper 5 and presses the stopper 5, the elastic driving member 53 is compressed, and the third stopper surface 215 of the first moving member 2 engages 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 in the second direction by the stopper 5 and the third moving member 4, the first moving member 2 can be positioned at the end position. When the third moving element 4 moves to the driving position, the fourth driving portion 44 cooperates with the third driving portion 32, and in the process that the third moving element 4 moves from the driving position to the end position, the third moving element 4 drives the second moving element 3 to move, the drain valve is opened, the third moving element 4 moves to the end position and can be kept at the end position according to the preset time, in the process, the first moving element 2 is not moved, when the clutch brake is released and the holding spring is held tightly, the impeller rotates to drive the inner barrel 500 to synchronously rotate, so that the water drainage can be realized.

After the drainage mode is completed, the transmission mechanism 100 needs to be reset, the power unit 200 stops working, the second elastic reset component drives the second control component to reset, so as to drive the second moving component 3 to move reversely to reset, in the process of the reverse movement of the second moving component 3, the fourth driving portion 44 is matched with the third driving portion 32, so as to drive the third moving component 4 to move reversely, when the third moving component 4 moves reversely by 14mm to the end position, the extrusion force of the third moving component 4 to the first moving component 2 in the second direction is reduced, the elastic driving component 53 extends and drives the limiting block 5 to move towards the direction adjacent to the first moving component 2, so as to drive the first moving component 2 to move towards the direction adjacent to the third moving component 4, so as to realize the reset of the first moving component 2 in the second direction, at this time, the second driving portion 433 of the third moving component 4 is matched with the first driving portion 212 of the first moving component 2 again, and the second position-limiting surface 214 of the first moving element 2 is disengaged from the first position-limiting portion 1131 and the third position-limiting surface 215 of the first moving element 2 is disengaged from the second position-limiting portion 1132, the first moving element 2 can move in the first direction.

At this time, the first elastic resetting 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 in this process, through the cooperation of the first driving portion 212 and the second driving portion 433, the first moving member 2 can drive the third moving member 4 to move reversely and reset to the initial position together, so as to realize the resetting of the transmission mechanism 100.
