Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

In order to facilitate description of the operation principle of the driving mechanism 400 of the laundry treating apparatus according to the embodiment of the present invention, the clutch assembly 100 and the drain valve 300 of the laundry treating apparatus according to the embodiment of the present invention will be described first, and the laundry treating apparatus may be, for example, a full-automatic pulsator washing machine.

A clutch assembly 100 according to an embodiment of the present invention is described below with reference to fig. 1-9. In particular, the clutch assembly 100 may be applied to a power transmission process of a laundry treating apparatus, which is an important component of the laundry treating apparatus capable of switching different operation modes.

As shown in fig. 1, a clutch assembly 100 according to an embodiment of the present invention includes a housing 11, a ratchet 12, a fork 13, and a shift block 14.

Referring to fig. 1, the ratchet 12 is located at one axial side (e.g., the lower side as shown in fig. 1) of the housing 11, a plurality of spaced teeth are provided on an outer circumferential wall of the ratchet 12, a shift fork 13 is located at an outer side of the housing 11 and one end of the shift fork 13 is rotatably coupled to the housing 11, and a first pawl 132 (see fig. 3) is provided on the shift fork 13.

As shown in fig. 1 and 2, the dial 14 is located at the outer side of the housing 11 and one end of the dial 14 is rotatably coupled to the fork 13, the other end of the dial 14 is rotatably coupled to the housing 11, the dial 14 is rotatably coupled to the second pawl 154, and the first pawl 132 and the second pawl 154 are spaced apart in the circumferential direction of the ratchet 12.

As shown in FIG. 4, the line of the inner end of the first pawl 132 with the central axis of the ratchet wheel 12 and the line of the inner end of the second pawl 154 with the central axis of the ratchet wheel 12 are not collinear in a plane perpendicular to the central axis of the ratchet wheel 12. That is, the connection points of the first and second pawls 132 and 154 with the ratchet 12 are not opposite in the radial direction, so that the assembly space between the fork 13, the block 14 and the ratchet 12 can be saved, and the clutch assembly 100 can be more compact.

Wherein, in the conventional washing mode (i.e., the inner tub of the laundry treating apparatus is not rotated, the pulsator rotates), referring to fig. 4, the first pawl 132 and the second pawl 154 are respectively engaged with different teeth of the ratchet wheel 12; in the dehydrating mode (i.e., the inner tub and pulsator of the laundry treating apparatus are rotated in synchronization), both the first and second pawls 132 and 154 are disengaged from the ratchet wheel 12.

For example, referring to fig. 4, the first pawl 132 is fixedly coupled to the shift fork 13, the second pawl 154 is rotatably coupled to the shift block 14, the rotation center line L1 of the shift fork 13 and the rotation center line L2 of the shift block 14 are located at opposite sides of the ratchet 12, respectively, an end portion of the first pawl 132 may be inserted between any two adjacent teeth of the ratchet 12, and an end portion of the second pawl 154 may be inserted between the remaining two adjacent teeth of the ratchet 12.

Further, the rotation of the fork 13 may drive one end of the shift block 14 to rotate relative to the other end of the shift block 14 (in other words, the rotation of the fork 13 may drive the shift block 14 to rotate about the rotation center line L2) such that the first pawl 132 and the second pawl 154 are engaged with or disengaged from the ratchet 12, respectively, and when the fork 13 rotates to a position such that the first pawl 132 and the second pawl 154 are engaged with different teeth of the ratchet 12, respectively, the clutch assembly 100 is in a normal washing mode such that the washing shaft 172 of the laundry treating apparatus is rotated and the dehydrating shaft 171 is in a free state; when the fork 13 is rotated such that both the first and second pawls 132 and 154 are disengaged from the ratchet 12, the clutch assembly 100 is in the dehydrating mode such that the dehydrating shaft 171 and the washing shaft 172 are simultaneously rotated.

The inventor found in practical studies that, in the related art, the fork 13 employs an integrated double pawl, and the fork 13 needs to be rotated by a large angle to disengage both pawls from the ratchet 12, resulting in a large rotational space required for the fork 13 when the clutch assembly 100 is switched between the dehydrating mode and the normal washing mode, and particularly, a very large distance from the pawl at one end far from the rotation center of the fork 13 to the central axis of the ratchet 12 in the dehydrating mode, increasing the space occupation of the clutch assembly 100.

According to the clutch assembly 100 of the embodiment of the present invention, the rotation of the shift fork 13 may drive one end of the shift block 14 to rotate relative to the other end of the shift block 14, so that the first pawl 132 and the second pawl 154 are respectively engaged with or disengaged from the ratchet 12, it is understood that the shift fork 13 and the shift block 14 are separately disposed, when the shift fork 13 rotates, the rotation direction of the shift block 14 is opposite to the rotation direction of the shift fork 13, so that the rotation direction of the first pawl 132 and the second pawl 154 is opposite, for example, when the first pawl 132 rotates clockwise, the second pawl 154 rotates counterclockwise, which is beneficial to enabling the first pawl 132 and the second pawl 154 to be disengaged from the ratchet 12 under the condition that the shift fork 13 rotates at a smaller angle, which is beneficial to reducing the rotation range of the shift fork 13 and the shift block 14, thereby reducing the space occupation of the clutch assembly 100, and saving the assembly space between the shift fork 13, the shift block 14 and the ratchet 12, so that the clutch assembly 100 has a more compact structure.

According to the clutch assembly 100 of the embodiment of the invention, the rotation of the shifting fork 13 can drive one end of the shifting block 14 to rotate relative to the other end of the shifting block 14, so that the first pawl 132 and the second pawl 154 are respectively matched with or separated from the ratchet 12, the shifting fork 13 and the shifting block 14 are separately arranged, and when the shifting fork 13 rotates, the rotation direction of the shifting block 14 is opposite to the rotation direction of the shifting fork 13, so that the rotation directions of the first pawl 132 and the second pawl 154 are opposite, and the first pawl 132 and the second pawl 154 are separated from the ratchet 12 under the condition that the shifting fork 13 rotates at a small angle, so that the rotation range of the shifting fork 13 and the shifting block 14 is reduced, and the space occupation of the clutch assembly 100 is reduced.

In some embodiments of the present invention, referring to fig. 4 and 5, the other end of the shift fork 13 is provided with a first pivoting portion 131 and a first pawl 132, respectively, the first pivoting portion 131 is disposed spaced apart from the first pawl 132 in the circumferential direction of the ratchet 12, the dial 14 is located at one side of the first pawl 132 adjacent to the first pivoting portion 131 and extends in the circumferential direction of the ratchet 12, a second pivoting portion 141 is provided at one end of the dial 14, and the first pivoting portion 131 is rotatably and movably connected to the second pivoting portion 141. Therefore, the rotatable connection of the shifting fork 13 and the shifting block 14 is convenient to realize, and the structure is simple, so that the processing and the forming are convenient.

Further, referring to fig. 4 and 5, the first pivot portion 131 is a first pivot shaft formed on the shift fork 13, and the second pivot portion 141 is a first pivot hole penetrating the shift block 14, the first pivot hole extending in a long shape along the circumferential direction of the ratchet 12. For example, as shown in fig. 4, the first pivot hole is formed in an oblong shape. It will be appreciated that the area of the first pivot hole is larger than the area of the first pivot shaft, such that there is a margin of movement and rotation between the first pivot portion 131 and the second pivot portion 141, facilitating the rotatable and movable connection of the first pivot portion 131 and the second pivot portion 141.

Further, as shown in fig. 5 and 6, the clutch assembly 100 includes a rotating block 15, a third pivot portion 151 and a fourth pivot portion 152 are provided on the rotating block 15, a rotation center line of the third pivot portion 151 is not collinear with a rotation center line of the fourth pivot portion 152, the third pivot portion 151 is rotatably connected with the housing 11, a fifth pivot portion 142 is provided on the dial 14, and the fifth pivot portion 142 is rotatably and movably connected with the fourth pivot portion 152; wherein the second pawl 154 is immovably provided on the rotating block, in other words, the second pawl 154 is fixedly connected with the rotating block. Therefore, when the shift fork 13 drives one end of the shift block 14 to rotate relative to the other end of the shift block 14, the rotating block 15 rotates around the rotation center line of the third pivot portion 151, so that the rotation track of the second pawl 154 is formed into a circular arc, which is beneficial to improving the reliability of the operation of the second pawl 154. For example, the third pivoting portion 151 is formed as a pivoting shaft, and the housing 11 is provided with a pivoting hole that mates with the third pivoting portion 151.

Alternatively, as shown in fig. 6, the fourth pivot portion 152 is a second pivot shaft, and the fifth pivot portion 142 is a second pivot hole formed in the dial 14, the second pivot hole extending in a long shape along the circumferential direction of the ratchet 12. It will be appreciated that the area of the second pivot aperture is larger than the area of the second pivot axis, such that there is a margin of movement and rotation between the fourth pivot portion 152 and the fifth pivot portion 142, facilitating rotatable and movable coupling of the fourth pivot portion 152 and the fifth pivot portion 142.

For example, as shown in fig. 6, the rotating block 15 is further provided with a sixth pivot portion 153, the sixth pivot portion 153 and the third pivot portion 151 are respectively located at the upper side and the lower side of the rotating block 15, the rotation center lines of the sixth pivot portion 153 and the third pivot portion 151 are located on the same straight line, the dial 14 is further provided with a seventh pivot portion 143, the seventh pivot portion 143 is rotatably and movably connected with the fourth pivot portion 152, the seventh pivot portion 143 is formed as a pivot hole and extends in a long shape along the radial direction of the ratchet 12, the seventh pivot portion 143 is communicated with the fifth pivot portion 142, the hole depth of the seventh pivot portion 143 is greater than the hole depth of the fifth pivot portion 142, and the length of the fourth pivot portion 152 is greater than the length of the sixth pivot portion 153, so that the fourth pivot portion 152 is prevented from sliding into the seventh pivot portion 143 from the fifth pivot portion 142, thereby ensuring the reliability of the operation of the rotating block 15.

In some embodiments of the present invention, as shown in fig. 4 and 7, the clutch assembly 100 further includes a fixed block 16, the fixed block 16 is non-movably provided on the housing 11, in other words, the fixed block 16 is fixedly connected to the housing 11, the other end of the dial 14 is rotatably connected to the fixed block 16, and the third pivot portion 151 is rotatably connected to the fixed block 16. It will be appreciated that the dial 14 is rotatably connected to the housing 11 by the fixing block 16, and the rotary block 15 is rotatably connected to the housing 11 by the fixing block 16, so that it is not necessary to provide the housing 11 with additional structures for respectively engaging the dial 14 and the rotary block 15, which is advantageous in reducing the production cost of the housing 11.

In some embodiments of the present invention, as shown in fig. 2, the clutch assembly 100 further includes a stator 18, the stator 18 being disposed on one axial side of the housing 11 and around the ratchet 12, and the fixed block 16 being disposed on the stator 18. For example, as shown in fig. 2, the stator 18 is formed in a ring shape, the top end of the stator 18 is provided with an inwardly turned flange 146 portion, the stator 18 is connected to one side of the housing 11 in the axial direction through the flange 146 portion, the fixed block 16 is provided on the flange 146 portion, the circumferential wall of the stator 18 is provided with a relief hole 181, one end of the fork 13 provided with the first pawl 132 extends into the stator 18 through the relief hole 181, and the fixed block 16, the rotary block 15 and the dial block 14 are all located between the ratchet 12 and the inner circumferential wall of the stator 18 (see fig. 4). Thus, by directly locating the stator 18 of the motor on the housing 11 with the ratchet 12 inside the stator 18, it is advantageous to further reduce the space occupation of the clutch assembly 100.

Furthermore, the inventor found in practical studies that since the opening of the stator 18 is limited, in other words, the distance from the inner circumferential wall of the stator 18 to the central axis of the stator 18 is limited, the related art integrated double pawl type fork 13 needs to be rotated by a large angle to disengage both pawls from the ratchet 12, and thus the clutch using the motor to directly drive the transmission shaft 175 cannot be applied.

In the clutch assembly 100 according to the embodiment of the present invention, the rotation of the shift fork 13 may drive one end of the shift block 14 to rotate relative to the other end of the shift block 14, so that the first pawl 132 and the second pawl 154 respectively engage with or disengage from the ratchet 12, it is understood that, when the shift fork 13 rotates, the shift fork 13 and the shift block 14 are separately disposed, and when the shift fork 13 rotates, the rotation direction of the shift block 14 is opposite to the rotation direction of the shift fork 13, so that the rotation directions of the first pawl 132 and the second pawl 154 are opposite, which is beneficial to enabling the first pawl 132 and the second pawl 154 to disengage from the ratchet 12 under the condition of a smaller rotation angle of the shift fork 13, so that the rotation range of the shift fork 13 and the shift block 14 can be reduced, thereby enabling the clutch assembly 100 according to the embodiment of the present invention to be suitable for the situation that the stator 18 has limited openings.

In some embodiments of the present invention, the fixed block 16 is provided with a first guiding surface 161, the first guiding surface 161 is an arc surface, the central axis of the cylindrical surface where the first guiding surface 161 is located is the rotation center line of the rotation of the shifting block 14 relative to the fixed block 16, and the shifting block 14 is provided with a second guiding surface 144 adapted to the first guiding surface 161. Thus, by the cooperation of the first guide surface 161 and the second guide surface 144, the rotation of the shift block 14 relative to the rotation center line of the fixed block 16 is facilitated to be ensured, and the reliable rotation of the shift block 14 is facilitated to be ensured.

Alternatively, as shown in fig. 6 and 8, the fixed block 16 is located between the housing 11 and the dial 14 in the axial direction, a side surface of the dial 14 facing the fixed block 16 extends toward a direction approaching the housing 11 to form a first connection section 145, the other end of the first connection section 145 is provided with a flange 146, a limit space 147 is defined between the flange 146 and the side surface of the dial 14 facing the fixed block 16, and a portion of the fixed block 16 is located in the limit space 147. Thereby, the mating area of the fixing block 16 and the shifting block 14 is advantageously increased, and the reliable rotation of the shifting block 14 is further advantageously ensured.

Further, as shown in fig. 8, a first guide surface 161 is formed on a portion of the inner surface of the limiting space 147 located in the first connection section 145, and a second guide surface 144 is formed on a portion of the fixing block 16 located in the limiting space 147. Thereby, it is advantageous to further increase the area of the guide engagement of the fixing block 16 and the dial 14, and to further secure the reliable rotation of the dial 14.

The different operating states of the clutch assembly 100 and the operating modes of the laundry treating apparatus in the different operating states of the clutch assembly 100 are described below.

When neither the shift lever 178 nor the shift fork 13 is operated, the brake belt locks the brake disc 173, and the clutch shaft 174, the brake disc 173 and the dehydrating shaft 171 are fixedly connected into a whole, so that the dehydrating shaft 171 cannot rotate, and the inner barrel connected with the dehydrating shaft 171 cannot rotate; the first pawl 132 and the second pawl 154 are in a state of being matched with the ratchet wheel 12, at the moment, the holding spring 177 is unscrewed, the holding spring 177 leaves the outer peripheral surfaces of the clutch sleeve 176 and the clutch shaft 174, so that the holding spring 177 is not coupled with the clutch sleeve 176 and the clutch shaft 174, the clutch sleeve 176 and the clutch shaft 174 are not coupled, and therefore, the power of the transmission shaft 175 is only transmitted to the washing shaft 172, so that a pulsator connected with the washing shaft 172 can rotate, in this state, the inner barrel is not moved, the pulsator rotates, and the clothes treatment equipment is in a conventional washing mode;

When the shifting fork 13 is not moved and the shifting lever 178 swings against the acting force of the shifting lever torsion spring, the shifting lever 178 can drive the brake belt to act so that the brake belt does not lock the brake disc 173 any more, the brake disc 173 is in a free state, therefore, the inner barrel is also in a free state, the inner barrel can rotate freely, at the moment, the first pawl 132 and the second pawl 154 are still in a state matched with the ratchet wheel 12, therefore, the embracing spring 177 is still in a unscrewed state, the power of the transmission shaft 175 is still only transmitted to the washing shaft 172, the washing shaft 172 drives the pulsator to rotate, the pulsator rotates to drive the water flow to rotate, the water flow drives the inner barrel to rotate, hysteresis exists between the rotation of the inner barrel and the rotation of the pulsator, and therefore, when the rotation direction of the inner barrel is opposite to the rotation direction of the pulsator, a similar hand rubbing washing effect can be formed, and in the hand rubbing washing mode of the clothes treatment equipment.

When the deflector rod 178 continues to swing, the brake disc 173 is still in a free state, the deflector rod 178 can be abutted with the adjusting screw, the adjusting screw forces the shifting fork 13 to rotate against the acting force of the shifting fork torsion spring, the first pawl 132 and the second pawl 154 are respectively separated from the ratchet wheel 12 under the driving of the shifting fork 13, the holding spring 177 is restored to a natural winding state, namely, the holding spring 177 is restored to the state that the holding spring 177 is attached to the outer peripheral surfaces of the clutch sleeve 176 and the clutch shaft 174, the clutch sleeve 176 and the clutch shaft 174 are coupled, and the clutch shaft 174 are coupled by friction to form transmission coupling in a twisting direction, at the moment, the power of the transmission shaft 175 can enable the dehydration shaft 171 and the washing shaft 172 to synchronously rotate, and the inner barrel and the pulsator to synchronously rotate, and in this state, the clothes treatment equipment is in a dehydration mode.

As shown in fig. 12 and 15, the transmission mechanism 400 of the laundry treating apparatus according to the embodiment of the present invention, the transmission mechanism 400 includes a first moving member 42, a limit seat 43, and a second moving member 44. Specifically, when the transmission mechanism 400 is applied to the laundry treating apparatus, in order to enable the function of the transmission mechanism 400, the laundry treating apparatus further includes a power unit 200, a first executing unit, and a second executing unit, as shown in fig. 10 and 11.

As shown in fig. 12 and 15, the first moving member 42 is adapted to be connected to the power unit 200 and move along a first direction (for example, a left-right direction in the drawing) under the driving of the power unit 200, the first moving member 42 moves to drive the first operating member of the first executing unit to move, the limiting seat 43 is disposed at one end of the first moving member 42 along the first direction, the limiting seat 43 can move along with the movement of the first moving member 42, the second moving member 44 is connected to the limiting seat 43 and is slidable in the first direction relative to the limiting seat 43, the second moving member 44 is adapted to be connected to the second operating member of the second executing unit, and the second moving member 44 can drive the second operating member to move under the driving of the limiting seat 43.

In the following description, the clutch assembly 100 mentioned above is taken as a first actuating unit, the lever 178 is taken as a first actuating unit, the drain valve 300 mentioned above is taken as a second actuating unit, and the return spring 31 is taken as a second actuating unit, wherein the power unit 200 can be, for example, a double-stroke tractor, and the double-stroke tractor is provided with a traction rope 21.

In the moving direction of the first mover 42, the movement of the first mover 42 includes a first stroke and a second stroke. Specifically, for example, the first movement member 42 moves a first stroke and then a second stroke during the movement from right to left.

In the first travel, the first moving member 42 drives the limiting seat 43 to move, the limiting seat 43 slides relative to the second moving member 44, and the second moving member 44 does not move; in this state, the lever 178 swings, the drain valve 300 is closed, and the laundry treating apparatus is in the hand scrubbing mode; in the second stroke, the first moving member 42 continues to drive the limiting seat 43 to move, and the limiting seat 43 drives the second moving member 44 to move synchronously, in this state, the driving lever 178 continues to swing, and at the same time, the drain valve 300 is opened, so that the laundry treating apparatus is in a dewatering mode, and thus, switching of multiple working modes of the laundry treating apparatus can be realized.

The operation of the transmission 400 will be described in further detail with reference to the structure of the clutch assembly 100 and the structure of the drain valve 300.

Specifically, when the transmission mechanism 400 is in an initial state (i.e., the first moving member 42 does not start moving the first stroke yet), the traction rope 21 of the power unit 200 is connected to the first moving member 42, the first moving member 42 is connected to the driving lever 178, the limiting seat 43 is mounted at the right end of the first moving member 42, the second moving member 44 is slidably connected to the limiting seat 43, the second moving member 44 is connected to the drain valve 300, and at this time, the power unit 200 is powered off and does not operate, the first moving member 42 does not move, and thus the driving lever 178, the limiting seat 43 and the second moving member 44 do not move. In this state, for the clutch assembly 100, the brake band is in a locked state, and the first and second pawls 132 and 154 are engaged with the ratchet 12, thereby immobilizing the inner tub of the laundry treating apparatus, the pulsator may be rotated while the valve core of the drain valve 300 is in a closed position, and the drain valve 300 is not drained, at which time the laundry treating apparatus may be in a normal washing mode.

When the power unit 200 starts to work, the traction rope 21 starts to pull the first moving member 42 to move leftwards to perform the action of the first stroke, and in the first stroke, the first moving member 42 drives the shift lever 178 to swing, and simultaneously drives the limiting seat 43 to move leftwards along with the first moving member 42, the limiting seat 43 slides leftwards relative to the second moving member 44, and the second moving member 44 still does not move. In this state, for the clutch assembly 100, the shift lever 178 drives the brake band to act so that the brake band does not lock the brake disc 173 any more, the brake disc 173 is in a free state, and the first pawl 132 and the second pawl 154 are still matched with the ratchet wheel 12, so that the inner drum of the clothes treatment device is in a free state, and the pulsator is in a rotating state, so that the pulsator can drive the inner drum to rotate through water flow after rotating; for the drain valve 300, the valve body of the drain valve 300 is still in the closed position, and the drain valve 300 does not drain water, at which time the laundry treating apparatus is in the hand washing mode.

When the power unit 200 continues to work, the traction rope 21 continues to pull the first moving member 42 to move leftwards for a second stroke, and in the second stroke, the first moving member 42 drives the shift lever 178 to continue to swing, the limiting seat 43 continues to move leftwards along with the first moving member 42, and meanwhile, the limiting seat 43 also drives the second moving member 44 to move leftwards. In this state, for the clutch assembly 100, the brake disc 173 is still in a free state, and the lever 178 abuts against the adjusting screw and forces the fork 13 to rotate by the adjusting screw so that the first pawl 132 and the second pawl 154 are disengaged from the ratchet 12, respectively, thereby allowing the inner tub and the pulsator to rotate synchronously; in the drain valve 300, the second moving member 44 moves leftwards, so that the return spring 31 connected to the second moving member 44 is stretched, and when the force of the return spring 31 is greater than the force of the external spring, the return spring 31 pulls the valve core to move to the open position to drain the drain valve 300, and the laundry treating apparatus is in the dehydrating mode.

When the power unit 200 is not operated any more, the power unit 200 is powered off, the traction rope 21 does not generate a pulling force on the first moving member 42 any more, at this time, under the acting force of the deflector rod torsion spring, the deflector rod 178 starts to reset, and meanwhile, as the second moving member 44 is connected with the reset spring 31 of the drain valve 300, the first moving member 42, the limiting seat 43 and the second moving member 44 move rightwards to reset to the initial state under the common driving of the reset spring 31 and the deflector rod 178.

In summary, by providing the transmission mechanism 400, the power unit 200, the clutch assembly 100 and the drain valve 300 of the laundry treatment apparatus can be connected, and the driving action of the power unit 200 can be distributed, so that the first moving member 42 can be moved or both the first moving member 42 and the second moving member 44 can be moved at a specific stroke position and time to adjust the working states of the first executing unit and the second executing unit, and further, the working modes of the laundry treatment apparatus can be adjusted, so as to meet different washing requirements of users.

In addition, here, instead of the first moving member 42 directly driving the second moving member 44 to move, a limiting seat 43 capable of being in sliding fit with the second moving member 44 is provided on the first moving member 42, and the limiting seat 43 only slides on the second moving member 44 of the first row Cheng Xiangdui, and the second moving member 44 can be driven to move in the second stroke, so that the limiting seat 43 can distribute the moving stroke of the first moving member 42, so that the first moving member 42 can drive the second moving member 44 to move only in the second stroke through the limiting seat 43, and the adjustment of the working mode of the clothes treating device is realized.

According to the transmission mechanism 400 of the clothes treating apparatus according to the embodiment of the invention, the first moving member 42 is provided with the limiting seat 43 which can be in sliding fit with the second moving member 44, the limiting seat 43 only slides on the second moving member 44 in the first row Cheng Xiangdui, and the second moving member 44 can be driven to move in the second stroke, so that the limiting seat 43 can distribute the moving stroke of the first moving member 42, the first moving member 42 can drive the second moving member 44 to move only in the second stroke through the limiting seat 43, and the adjustment of the working mode of the clothes treating apparatus is realized.

In some embodiments of the present invention, as shown in fig. 13, the transmission mechanism 400 includes a mounting seat 41, the mounting seat 41 has a mounting cavity 411, one end of the mounting seat 41 in a first direction (e.g., a left-right direction) has a first opening 4111 communicating with the mounting cavity 411, and the other end of the mounting seat 41 in the first direction has a second opening 4112 communicating with the mounting cavity 411, thereby being simple in structure.

Specifically, for example, referring to fig. 13, the left end of the mount 41 has a first opening 4111, the first opening 4111 communicates with the mount cavity 411, the right end of the mount 41 has a second opening 4112, and the second opening 4112 communicates with the mount cavity 411. In practice, the mounting seat 41 is generally immovably mounted within the cabinet 500 of the laundry treating apparatus.

As shown in fig. 12, at least part of the first moving member 42 is located in the mounting cavity 411, and the first moving member 42 is movable in a first direction (e.g., a left-right direction) with respect to the mounting seat 41. It will be appreciated here that during movement of first mover 42, first mover 42 may be always within mounting cavity 411; alternatively, the movement of the first moving member 42 has two extreme positions, the first moving member 42 being located in the mounting cavity 411 when the first moving member 42 is located in one of the extreme positions, and the first moving member 42 being partially located in the mounting cavity 411 when the first moving member 42 is located in the other of the extreme positions; or, during the moving process of the first moving member 42, the first moving member 42 is always partially located in the mounting cavity 411, so that the mounting cavity 411 can play a certain role in protecting the first moving member 42.

As shown in fig. 11 and 12, the first motion member 42 is adapted to be coupled to a first operating member of a first actuator unit (e.g., a lever 178 of the clutch assembly 100). In practical applications, for example, the portion of the first moving member 42 exposed from the mounting cavity 411 is connected to the lever 178; alternatively, the peripheral wall of the mounting seat 41 is provided with a avoidance gap 416 that is communicated with the mounting cavity 411, and the driving lever 178 passes through the avoidance gap 416 and is connected with the first moving member 42 in the mounting cavity 411, however, other modes can be adopted for connecting the first moving member 42 and the driving lever 178, which is not limited by the invention.

As shown in fig. 13, one end of the first moving member 42 is adapted to be connected to the power unit 200 through the first opening 4111, that is, one end of the first moving member 42 passes through the first opening 4111 and is located outside the mounting cavity 411 to be connected to the power unit 200, or the power unit 200 extends into the mounting cavity 411 through other connectors to be connected to one end of the first moving member 42.

In practical applications, for example, one end of the first moving member 42 may extend out of the mounting cavity 411 through the first opening 4111 to be connected to the traction rope 21 of the power unit 200; or the traction rope 21 of the power unit 200 extends into the mounting cavity 411 through the first opening 4111 to be connected to one end of the first moving member 42, however, other manners of connecting the first moving member 42 to the lever 178 are also possible, which is not limited by the present invention.

As shown in fig. 12, at least part of the second moving member 44 is located in the mounting cavity 411, and the second moving member 44 is movable in the first direction relative to the mounting seat 41. It will be appreciated here that during movement of the second moving member 44, the second moving member 44 may be always within the mounting cavity 411; alternatively, the movement of the second moving member 44 has two extreme positions, the second moving member 44 being located in the mounting cavity 411 when the second moving member 44 is located in one of the extreme positions, and the second moving member 44 being partially located in the mounting cavity 411 when the second moving member 44 is located in the other of the extreme positions; alternatively, the second mover 44 is always partially located within the mounting cavity 411 during movement of the second mover 44. Whereby the mounting cavity 411 can provide a certain protection for the second movement 44.

The second moving member 44 is connected to the first moving member 42 and is relatively movable in a first direction, i.e. the second moving member 44 is movable both with respect to the mounting 41 and with respect to the first moving member 42, and likewise the first moving member 42 is movable with respect to the second moving member 44.

As shown in fig. 10 and 12, one end of the second moving member 44 is adapted to be connected to a second operating member (e.g., the drain valve 300) through the second opening 4112. For example, it may be that one end of the second moving member 44 protrudes to the outside of the installation cavity 411 through the second opening 4112 to be connected to one end of the return spring 31 of the drain valve 300 (e.g., the free end of the return spring 31 above); or one end of the return spring 31 of the drain valve 300 (e.g., the free end of the return spring 31 described above) protrudes into the mounting cavity 411 through the second opening 4112 to be coupled to the second moving member 44.

In some embodiments of the present invention, as shown in fig. 12 and 13, a surrounding wall of the mounting seat 41 is provided with a avoidance gap 416 in communication with the mounting cavity 411, and the first control element (for example, the lever 178) passes through the avoidance gap 416 and is connected to the first moving element 42, thereby having a simple structure.

Specifically, a side wall of the mounting seat 41 along a second direction (for example, a front-rear direction) is provided with a avoidance notch 416 communicating with the mounting cavity 411, and the second direction is perpendicular to the first direction. For example, referring to fig. 13 and 14, the front side wall of the mounting seat 41 is provided with a avoidance notch 416, the avoidance notch 416 is approximately rectangular, the avoidance notch 416 is communicated with the mounting cavity 411, the first moving member 42 is provided with a positioning through hole 424, the positioning through hole 424 extends along the front-rear direction, the positioning through hole 424 is always communicated with the avoidance notch 416, and the driving lever 178 penetrates through the avoidance notch 416 to extend into the positioning through hole 424 and is matched with the positioning through hole 424, so that when the first moving member 42 moves leftwards, the first moving member 42 can push the driving lever 178 to swing, and the connecting mode does not need an additional connecting member, and has a simple structure and is convenient to assemble.

In some embodiments of the present invention, in order to facilitate the connection of the traction rope 21 of the power unit 200 to the first moving member 42, as shown in fig. 14, a positioning groove 425 is provided on the first moving member 42, and a positioning opening communicating with the positioning groove 425 is provided on a side wall of the first moving member 42 adjacent to the first opening 4111 (for example, a left side wall of the first moving member 42).
