Then the power unit pulls the first moving part 12 to move along the original direction again, under the condition of abutting against the third moving part 16 or tensioning the third moving part 16, the first moving part 12 can drive the operation control part 32 of the second execution unit 3 to move through the third moving part 16, so as to open the second execution unit 3 for draining, in the process of moving the operation control part 32 of the second execution unit 3, because the abutting state of the first moving part 12 and the second moving part 14 is released and the first moving part 12 and the second moving part 14 move relatively, it can be ensured that the second moving part 14 can not continuously drive the operation control part 42 of the first execution unit 4 to move, or the operation control part 42 of the first execution unit 4 can not move to the maximum stroke, and the operation control part 42 of the first execution unit 4 is effectively prevented from being excessively driven due to the synchronous driving of the second moving part 14 in the process of driving the operation control part 32 of the second execution unit 3 to move, resulting in damage to the first execution unit 4, etc.

During the traction process of the power unit 2, when the first period of time sequence movement is performed, the second execution unit 3 is not dragged or is not dragged to be opened, the control piece 42 of the first execution unit 4 swings until the first execution unit 4 is in a separated state, and particularly, under the condition that the first execution unit 4 is a clutch, the second execution unit 3 is a drain valve, and the power unit 2 is a tractor, the rotation of a dehydration barrel or the rotation of a pulsator of the clothes treatment device is facilitated, so that the washing of the dehydration barrel or the washing of clothes are performed; during the second period of time sequence movement, the control member 42 of the first execution unit 4 is not moved or moved so as not to be pulled to the maximum stroke, and the second execution unit 3 can be completely opened, which is beneficial to draining water. The draining of the laundry treating apparatus, such as a washing machine, and the opening of the first performing unit 4 for performing the dehydrating operation may be controlled by one power unit 2.

Alternatively, the power unit 2 and the first moveable member 12 may be connected by a pull cord 22.

It should be noted that, in the present application, the control member 42 of the first execution unit 4 belongs to a part of the first execution unit 4, and the movement of the control member can adjust the first execution unit 4 to be in the separated state, and optionally, the control member 42 of the first execution unit 4 is a shift lever. Similarly, the control 32 of the second execution unit 3 is part of the second execution unit 3, and the movement of the control can adjust the second execution unit 3 to the open state.

In some embodiments, as shown in fig. 4 to 6, the transmission mechanism 1 further includes: a first transmission part movably arranged on the second movable piece 14; the second transmission part is arranged on the first moving part 12 and is used for abutting against the first transmission part so as to drive the second moving part 14 to move; and a third transmission portion disposed on a moving path of the second movable member 14, for releasing the abutting state of the first transmission portion and the second transmission portion, so as to relatively move the first movable member 12 and the second movable member 14.

In this embodiment, the first transmission portion is movably disposed on the second movable member 14, and the first transmission portion abuts against the second transmission portion disposed on the first movable member 12, so that the first movable member 12 drives the second movable member 14 to move synchronously. And through setting up the third transmission portion on the moving path of second moving part 14, in the process that first transmission piece moved to passing through the third transmission portion, the third driving medium can cause first transmission portion to remove for second moving part 14 to make first transmission portion separate with second transmission portion, be favorable to realizing first moving part 12 and second moving part 14 relative movement.

Optionally, the second transmission member is integrally formed with the first movable member 12.

In some embodiments, as shown in fig. 4 to 6, the transmission mechanism 1 further includes: the bracket 18, the bracket 18 is provided with a channel; the first transmission part is a movable pin 142, the second movable part 14 is provided with a through hole 144, and the movable pin 142 partially extends into the through hole 144 and partially extends out of the through hole 144; the second transmission part is a limit groove 122 and is arranged on the outer surface of the first movable part 12; the third transmission portion is an escape groove 182 provided on an inner wall surface of the passage in which the second movable element 14 can move.

In this embodiment, the transmission mechanism 1 further comprises a bracket 18, and the transmission mechanism 1 is fixedly arranged in the clothes treatment device through the bracket 18 and can be connected with the internal structure of the clothes treatment device through screws. The bracket 18 is provided with a passage which can be partially enclosed by the bracket 18, and the second movable member 14 is arranged in the passage to move along the passage, so that the moving stability of the second movable member 14 is improved. In addition, by arranging the limiting groove 122 on the outer surface of the first moving member 12 and arranging the movable pin 142 in the through hole 144 of the second moving member 14, when the portion of the movable pin 142 extending out of the through hole 144 extends into the limiting groove 122, along with the movement of the first moving member 12, the movable pin 142 can abut against the side wall of the groove of the limiting groove 122 deviating from the advancing direction thereof, and because the movable pin 142 is partially arranged in the through hole 144, the second moving member 14 can be driven to move, and in the process, the movable pin 142 is not excessively moved up and down by being limited by the bottom wall of the limiting groove 122 and the inner wall of the channel. When the movable pin 142 moves to the avoiding groove 182, because the first movable member 12 continues to advance, the groove sidewall of the limiting groove 122 can push the movable pin 142 to move until moving out of the limiting groove 122, and at this time, the portion of the movable pin 142 extending out of the through hole 144 extends into the avoiding groove 182, which is beneficial to realizing the relative movement between the first movable member 12 and the second movable member 14. In addition, by positioning the movable pin 142 in the through hole 144, the movable pin 142 transmits the traction force, thereby preventing the first movable member 12 and the second movable member 14 from being locked and ensuring smooth relative movement therebetween.

Alternatively, the stopper groove 122 may be configured by a groove penetrating the end surface of the first movable member 12 facing the power unit 2, and may also be configured by an outer circumferential surface of the first movable member 12 and a stopper protrusion provided on the outer circumferential surface of the first movable member 12.

Of course, the bracket 18 may not define a channel, but only has a guide rail for the second movable member 14 to move, and an avoiding groove 182 is formed in the guide rail, so that the portion of the movable pin 142 extending out of the through hole 144 can be separated from the limiting groove 122 under the action of gravity, and the portion of the movable pin 142 falls into the avoiding groove 182.

In some embodiments, the first transmission portion may also be a ball. The rolling effect is good, the generated friction force is small, the noise is low, and smooth relative movement of the first movable part 12 and the second movable part 14 is facilitated.

In addition, the first transmission portion may not be the movable pin 142 or the ball, but include a support rod, a swing rod and a spring, the swing rod is rotatably disposed on the second movable member 14 through the support rod, the spring is supported at one end of the swing rod, in the process that the first movable member 12 drives the second movable member 14 to move, the swing rod swings clockwise to a position abutting against the second transmission portion, and the spring is in a compressed state. The third transmission part is a limiting bulge, after the swing rod moves to abut against the limiting bulge, the spring is further compressed, and the swing rod swings anticlockwise and is separated from the second moving part 14, so that the first moving part 12 and the second moving part 14 move relatively. The swing rod can cross the limiting bulge in the anticlockwise swinging process, one end of the swing rod is far away from the second moving part 14, and after the swing rod crosses the limiting bulge, even if the swing rod is reset under the support of the spring, the swing rod cannot be abutted to the second transmission part any more due to the relative movement of the first moving part 12 and the second moving part 14.

In some embodiments, as shown in fig. 4-6, during movement of second moveable member 14, the portion of moveable pin 142 extending out of through-hole 144 disengages from retaining slot 122 and the portion of moveable pin 142 extends into clearance slot 182.

In this embodiment, when the second movable member 14 is set to move, a portion of the movable pin 142 extending out of the through hole 144 can be separated from the limiting groove 122 and partially extend into the avoiding groove 182, and a state that the first movable member 12 and the second movable member 14 are abutted against each other by the movable pin 142 partially extending into the limiting groove 122 can be released, so that the first movable member 12 can move relative to the second movable member 14.

In some embodiments, as shown in fig. 4 and 6, during the movement of the first movable member 12 driving the second movable member 14, the portion of the movable pin 142 extending out of the through hole 144 contacts the groove sidewall 122a of the limiting groove 122 to separate, the first movable member 12 continues to move, and the portion of the movable pin 142 extending out of the through hole 144 contacts the groove sidewall 182a of the avoiding groove 182.

In this embodiment, when the first moving member 12 drives the second moving member 14 to move, the portion of the movable pin 142 extending out of the through hole 144 can be separated from the groove sidewall 122a of the limiting groove 122 by abutting, so as to stably drive the second moving member 14 to move, which is beneficial for the first moving member 12 to drive the second moving member 14 to move synchronously; after the first movable member 12 continues to move, the portion of the movable pin 142 extending out of the through hole 144 can abut against the groove sidewall 182a of the bypass groove 182, which facilitates stable relative movement between the first movable member 12 and the second movable member 14.

In some embodiments, as shown in fig. 4 and 6, during the movement of the first movable member 12, the movable pin 142 changes from abutting between the groove side wall 122a of the limiting groove 122 and the inner wall surface of the bracket 18 to abutting between the groove side wall 182a of the avoiding groove 182 and the outer wall surface of the first movable member 12.

In this embodiment, by setting the first movable member 12 to move, the movable pin 142 can be changed from abutting between the groove side wall 122a of the limiting groove 122 and the inner wall surface of the bracket 18 to abutting between the groove side wall 182a of the avoiding groove 182 and the outer wall surface of the first movable member 12, which is beneficial to ensuring that the first movable member 12 moves stably relative to the second movable member 14 and preventing the first movable member 12 from continuously driving the second movable member 14 to move. Moreover, since the movable pin 142 abuts against the groove side wall 182a of the escape groove 182, the position of the movable pin 142 can be restricted, so that the movable pin 142 can be inserted into the limit groove 122 again after the first movable member 12 moves in the reverse direction.

In some embodiments, as shown in fig. 2 and 8, a position-limiting portion 124 is disposed on a portion of the first movable member 12 extending out of the channel, and the first movable member 12 moves under the pushing and pulling of the power unit 2 until the position-limiting portion 124 abuts against the bracket 18.

In this embodiment, the limiting portion 124 may be disposed on the outer peripheral surface of the end of the first movable member 12 away from the channel, and the limiting portion 124 abuts against the wall surface at the inlet of the channel, so as to effectively limit the moving distance of the first movable member 12, and prevent the first movable member 12 from moving excessively and pulling the operating member 32 of the second execution unit 3 excessively, which may damage the second execution unit 3.

In some embodiments, the transmission mechanism 1 further comprises: a fourth transmission portion (not shown in the figures) movably disposed on the first movable member 12; a fifth transmission portion (not shown) provided on the second movable member 14 for abutting against the fourth transmission portion; and a sixth transmission portion (not shown) disposed on the moving path of the first movable member 12 for releasing the contact between the fourth transmission portion and the fifth transmission portion to move the first movable member 12 and the second movable member 14 relatively.

In this embodiment, the fourth transmission portion is movably disposed on the first movable member 12, and the fourth transmission portion abuts against the fifth transmission portion disposed on the second movable member 14, so that the first movable member 12 drives the second movable member 14 to move synchronously. And through set up the sixth transmission portion on the moving path of first moving part 12, in the process that the fourth driving medium moved to passing through the sixth transmission portion, the sixth driving medium can cause the fourth transmission portion to move relative to first moving part 12 to make fourth transmission portion and fifth transmission portion separate, be favorable to realizing first moving part 12 and second moving part 14 relative movement.

Specifically, the fourth transmission portion may include a support rod, a swing rod and a spring, the swing rod is rotatably disposed on the first movable member 12 through the support rod, the spring is supported at one end of the swing rod, the swing rod swings counterclockwise to a position abutting against the fifth transmission portion in a process that the first movable member 12 drives the second movable member 14 to move, and the spring is in a compressed state. The sixth transmission part is a limiting bulge, after the swing rod moves to abut against the limiting bulge, the spring is further compressed, and the swing rod swings clockwise and is separated from the second moving part 14, so that the first moving part 12 and the second moving part 14 move relatively. The swing rod can cross the limiting bulge in the clockwise swinging process, one end of the swing rod is far away from the second moving part 14, and after the swing rod crosses the limiting bulge, the swing rod can not abut against the fifth transmission part any more due to relative movement of the first moving part 12 and the second moving part 14 even if the swing rod is reset under the support of the spring.

In the case that the second movable member 14 is a frame structure and the first movable member 12 passes through the frame structure, one end of the swing link can extend out of the first movable member 12 to abut against the support rod 146 of the frame structure. During the relative movement between the first movable member 12 and the second movable member 14, even if the swing link extends into the second movable member 14, the swing link only moves in the cavity between two adjacent support rods 146, and does not interfere with the second movable member 14.

In some embodiments, as shown in fig. 7, second movable member 14 includes a first plate 148, a second plate 150, and a plurality of struts 146 supported between first plate 148 and second plate 150; the first movable member 12 extends into the space between the first plate 148 and the second plate 150 and penetrates the second movable member 14, and the second movable member 14 is in contact with the operating member 42 of the first actuating unit 4 through a plurality of support rods 146.

In this embodiment, it is assumed that the second movable member 14 is constructed by a first plate 148, a second plate 150 and a plurality of support rods 146, the plurality of support rods 146 are supported between the first plate 148 and the second plate 150, and the second movable member 14 is in a frame structure, so that the first movable member 12 can conveniently extend into the frame structure, thereby improving the stability of the movement of the first movable member 12 relative to the second movable member 14. In addition, the supporting rod 146 far away from the advancing direction of the first movable member 12 in the plurality of supporting rods 146 is in contact with the operating control member 42 of the first execution unit 4, so that the operating control member 42 of the first execution unit 4 is driven to move, and the operating control member 42 of the first execution unit 4 extending into the frame is ensured to be driven by the second movable member 14. In the process that the first movable member 12 drives the second movable member 14 to move, the operating member 42 of the first executing unit 4 moves along with the first executing unit, and the end portion of the operating member gradually moves towards the outside of the second movable member 14, so that in the process that the first movable member 12 and the second movable member 14 move relatively, the operating member 42 of the first executing unit 4 is away from the first movable member 12, so that the first movable member 12 cannot drive the operating member 42 of the first executing unit 4 to move.

Alternatively, the direction in which the power unit 2 draws the first movable member 12 is set to the front, and the operating member 42 of the first actuating unit 4 is inserted into the second movable member 14 from either of the left and right sides with respect to the front.

Optionally, the first movable member 12 is provided with a first avoiding hole (not shown in the figure) for the operating member 42 of the first executing unit 4 to extend into, and the first avoiding hole extends along the moving direction of the first movable member 12. The arrangement of the first avoiding hole provides a space for the movement of the control member 42 of the first execution unit 4, and can effectively prevent the first moving member 12 from moving relative to the second moving member 14 to drive the control member 42 of the first execution unit 4 to move, which causes the control member 42 of the first execution unit 4 to be excessively stressed, thereby damaging the first execution unit 4.

Alternatively, the first movable member 12 may also be constructed as a frame structure by two plates and a plurality of support rods, and even if the control member 42 of the first execution unit 4 extends into the first movable member 12, the control member 42 of the first execution unit 4 will not be driven to move in the process of moving the first movable member 12 relative to the second movable member 14.

In some embodiments, as shown in fig. 4 to 6, the third movable member 16 is movably connected to the first movable member 12, and the third movable member 16 is provided with an abutting portion 162 for abutting against the first movable member 12; during the movement of the control member 42 of the first actuator unit 4, the first movable member 12 is separated from the contact portion 162.

In this embodiment, by setting the third movable member 16 to be movably connected to the first movable member 12, after the first movable member 12 moves to abut against the abutting portion 162, the third movable member 16 can be driven to move synchronously, so as to drive the operating member 32 of the second execution unit 3 to move, and open the second execution unit 3, such as a drain valve, for draining water. In the process of moving the control member 42 of the first executing unit 4, the first movable member 12 is separated from the abutting portion 162, so that the first executing unit 4 is prevented from being opened, and the second executing unit 3 is certainly opened along with the opening of the first executing unit 4, such as the clutch is separated, which is beneficial to realizing the independent washing function of the laundry treatment apparatus. Optionally, the third movable element 16 is connected to the control element 32 of the second actuating unit 3 by a pull cord. Of course, the third movable element 16 can also be connected directly to the control element 32 of the second actuating unit 3.

In this embodiment, the third movable member 16 is a pulling rope, and one end of the third movable member 16 away from the second movable member 14 is connected to the operating member 32 of the second execution unit 3, so that after the first movable member 12 moves and pulls the third movable member 16 to tighten, the operating member 32 of the second execution unit 3 can be driven to move to open the second execution unit 3, for example, to open the drain valve to drain water. In the process of moving the control member 42 of the first execution unit 4, the third movable member 16 is ensured to be in a loose state, i.e., a non-tight state, so that the opening of the first execution unit 4, such as the opening of the drain valve, which is accompanied by the opening of the second execution unit 3 when the clutch is disengaged, can be avoided, and the realization of the separate washing function of the laundry treatment apparatus is facilitated. In addition, the third moving part 16 is set as a traction rope, which is beneficial to being applicable to various complex environments in the clothes treatment device, and the operation part 32 of the second execution unit 3 can be connected after turning for many times, so that the occupied space is reduced, and the reasonable distribution of the internal space of the clothes treatment device is facilitated.

In some embodiments, as shown in fig. 2, one end of the first movable member 12 is provided with a receiving cavity 126, and the third movable member 16 is inserted into the receiving cavity 126 and moves in the receiving cavity 126; the abutting portion 162 is a limiting protrusion and is disposed on the outer peripheral surface of the third moving member 16, a second avoiding hole 128 is disposed on the cavity wall of the accommodating cavity 126, and the hole wall of the second avoiding hole 128 abuts against the limiting protrusion, so that the first moving member 12 drives the third moving member 16 to move.

In this embodiment, the receiving cavity 126 is formed at one end of the first movable member 12, and the third movable member 16 is inserted into the receiving cavity 126 and moves in the receiving cavity 126, so that the smoothness of movement of the third movable member 16 is improved. By providing the abutting portion 162, specifically, a limiting protrusion, on the outer peripheral surface of the third moving member 16, and forming the second avoiding hole 128 on the cavity wall of the accommodating cavity 126, when the hole wall of the second avoiding hole 128 of the first moving member 12 abuts against the limiting protrusion, the third moving member 16 can be driven to move synchronously, so as to drive the operating member 32 of the second executing unit 3 to move.

Optionally, the second avoidance hole 128 is the same avoidance hole as the first avoidance hole.

In some embodiments, as shown in fig. 1, the operating member 32 of the second executing unit 3 includes an elastic restoring member, and the third moving member 16 is directly or indirectly connected to the elastic restoring member; after the power unit 2 stops pushing and pulling, the third movable member 16 is reset under the elastic force of the elastic reset member.

In some embodiments, power unit 2 is a two-stroke power unit.

In this embodiment, the power unit 2 is set as a two-stroke power unit, but may be other multi-stroke power units, and is not limited to the two-stroke power unit.

As shown in fig. 1, a second aspect embodiment of the present invention provides a laundry treating apparatus, including: a power unit 2; a first execution unit 4; a second execution unit 3; and a transmission 1 as in any one of the previous embodiments.

The clothes treatment device provided by the invention only needs to configure one power unit 2 for the first execution unit 4 and the second execution unit 3, thereby saving the cost, reducing the occupied space and simplifying the action complexity of the power unit 2. Moreover, the power unit 2 is provided with the transmission mechanism 1 according to any of the above embodiments, which is beneficial to achieve the beneficial effects of any of the above embodiments, and is not repeated herein.

Alternatively, the transmission mechanism 1 may be disposed on the power unit 2, and disposed as an integral structure with the power unit 2, or the transmission mechanism 1 may be disposed on the second execution unit 3, and disposed as an integral structure with the second execution unit 3, or of course, the transmission mechanism 1 may be independently disposed in the laundry treatment apparatus.

Of course, the first execution unit 4 or the second execution unit 3 may be a water inlet valve, or the like, and is not limited to a clutch or a water discharge valve. The power unit 2 may also comprise a stepper motor or an electromagnetic drive, etc.

Alternatively, the power unit 2 is fixed inside the laundry treating apparatus by screws. The first and

second actuators

4 and 3 are fixed in position inside the laundry treating apparatus.

In some embodiments, the transmission 1 is disposed between the power unit 2 and the second actuator unit 3, and the first actuator unit 4 is disposed on one side of the transmission 1.

In this embodiment, the power unit 2, the transmission mechanism 1 and the second execution unit 3 may be arranged in a row, or may be arranged in a broken line after connecting the three.

In summary, the transmission mechanism 1 provided by the present invention can control the first execution unit 4 and the second execution unit 3 separately in time sequence, so as to realize an integrated control design with a new water flow washing program.

Hereinafter, the transmission process of the transmission mechanism 1 according to an embodiment of the present invention will be described in detail:

as shown in fig. 4, the first period of time acts as: the control clutch (as the first actuator unit 4) is opened and the drain valve (as the second actuator unit 3) is not opened. The first stroke of the retractor (as the power unit 2) will be pulled a distance to the left, and stop, and keep stressed and motionless, and pull the first movable part 12 to move to the left, at this time, the first movable part 12 and the second movable part 14 are connected into a whole through the movable pin 142, the movable pin 142 can only control to move in this space, the stress mode is as shown in fig. 9, the movable pin 142 cannot move up and down greatly, and the second movable part 14 is also moved to the left by the reaction force of the leftward force of the movable pin 142, and then the control element 42 of the clutch is controlled to move to the left. The third moveable member 16 is now unstressed and does not move and does not pull on the drain valve operating member 32.

As shown in fig. 5, when the first-stage sequential operation is switched to the second-stage sequential operation: the first movable member 12 continues to move to the left and at this point, as the longitudinal space of the channel in the bracket 18 increases, the movable pin 142 is forced longitudinally upward, sliding upward and up the track as shown in FIG. 10, and will no longer move with the first movable member 12, and the second movable member 14 will separate from the first movable member 12 and become non-integral. At this point, the second movable member 14 is no longer moving, and is only subject to the leftward reaction force of the movable pin 142 and the rightward force of the clutch operating member, so that the forces are balanced and the clutch operating member is no longer moving. And at this moment, the first movable member 12 and the third movable member 16 start to abut against each other, so as to generate an interaction force, the third movable member 16 starts to move leftward, and the third movable member 16 starts to pull the operating member 32 of the drain valve leftward, so as to start to pull open the drain valve.

As shown in fig. 6, the second stage sequence acts as: continuing with the motion state at the transition time, the clutch actuation member 42 is no longer moving and the first moveable member 12 continues to pull the third moveable member 16 until the drain valve is fully opened, at which point the retractor is in tension and remains stationary at the end of the second stroke. Referring to the force diagram of the movable pin 142 in the second sequence of fig. 11, the movable pin 142 is balanced, and the second moveable member 14 remains stationary during the entire process, the operating member 42 of the clutch is stationary, and the first moveable member 12 pulls the third moveable member 16 to the left until the drain valve is completely opened and then stops moving.

The reset action of the elastic reset piece: when the double-stroke tractor is powered off, the double-stroke tractor does not produce pulling force any more. First, the pulling ring of the elastic reset member is an elastic pulling ring, the pulling force thereof pulls the third moving member 16 and the first moving member 12 to move rightwards, and the pulling force is pulled to a state at a moment when the first period of time sequence action is converted to the second period of time sequence action, at this moment, the movable pin 142 rolls towards the center direction due to the change of the position of the first moving member 12, and returns to the initial state, the first moving member 12 and the second moving member 14 form an integral structure through the movable pin 142, and the stroke of the reset force of the clutch control member enables the first moving member 12 and the second moving member 14 to return to the initial positions. The force stroke of the resilient return member causes the third moveable member 16 to return to the initial position.

Up to this point, the transmission 1 and the respective components are restored to the initial positions.

Optionally, the retractor has a first time sequence of 15mm to 25mm travel and a second time sequence of 25mm to 45mm travel. The clutch is pulled open in the first time sequence, and the drain valve is pulled open in the second time sequence.
