Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

For convenience of describing the operation principle of the transmission 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, which may be, for example, a full-automatic pulsator washing machine, are first described herein.

A clutch assembly 100 according to an embodiment of the invention is described below with reference to fig. 1-9. In particular, the clutch assembly 100 can be applied to the power transmission process of the laundry treating apparatus, and is an important component of the laundry treating apparatus capable of realizing the switching between 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 dial 14.

Referring to fig. 1, the ratchet 12 is located at one axial side (e.g., a lower side as viewed in fig. 1) of the housing 11, the ratchet 12 is provided at an outer circumferential wall thereof with a plurality of spaced teeth, the yoke 13 is located at an outer side of the housing 11 and one end of the yoke 13 is rotatably connected to the housing 11, and the yoke 13 is provided with a first pawl 132 (see fig. 3).

As shown in fig. 1 and 2, the dial 14 is located outside the housing 11, one end of the dial 14 is rotatably connected to the shift fork 13, the other end of the dial 14 is rotatably connected to the housing 11, the dial 14 is rotatably connected to a second pawl 154, and the first pawl 132 and the second pawl 154 are spaced apart from each other in the circumferential direction of the ratchet 12.

As shown in fig. 4, the line connecting the inner end of the first pawl 132 and the center axis of the ratchet wheel 12 and the line connecting the inner end of the second pawl 154 and the center axis of the ratchet wheel 12 in a plane perpendicular to the center axis of the ratchet wheel 12 are not collinear. That is, the joints of the first pawl 132 and the second pawl 154 with the ratchet wheel 12 are not opposite in the radial direction, so that the assembly space between the shift fork 13, the dial 14 and the ratchet wheel 12 can be saved, and the structure of the clutch assembly 100 can be more compact.

Wherein, in a normal washing mode (i.e., the inner tub of the laundry treating apparatus is not rotated, the pulsator is rotated), as shown in fig. 4, the first and

second pawls

132 and 154 are engaged with different teeth of the ratchet 12, respectively; in the dehydration mode (i.e., the inner tub and the pulsator of the laundry treating apparatus are rotated in synchronization), both the first and

second pawls

132 and 154 are disengaged from the ratchet 12.

For example, referring to FIG. 4, first pawl 132 is fixedly coupled to fork 13, second pawl 154 is rotatably coupled to block 14, center line of rotation L1 of fork 13 and center line of rotation L2 of block 14 are located on opposite sides of ratchet wheel 12, an end of first pawl 132 is insertable between any two adjacent teeth of ratchet wheel 12, and an end of second pawl 154 is insertable between the remaining two adjacent teeth of ratchet wheel 12.

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

second pawls

132 and 154 are both disengaged from the ratchet wheel 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 adopts an integral double pawl, and the fork 13 needs to rotate by a large angle to disengage both pawls from the ratchet 12, so that when the clutch assembly 100 is switched between the dehydration mode and the conventional washing mode, the rotation space required by the fork 13 is large, and particularly, in the dehydration mode, the distance from the pawl at the end far away from the rotation center of the fork 13 to the central axis of the ratchet 12 is very large, thereby increasing the space occupation of the clutch assembly 100.

According to the clutch assembly 100 of the embodiment of the invention, the rotation of the shift fork 13 can 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 matched with or separated from the ratchet wheel 12, and it can be understood that the shift fork 13 and the shift block 14 are separately arranged, when the shift fork 13 rotates, the rotation direction of the shift block 14 is opposite to that of the shift fork 13, so that the rotation directions of the first pawl 132 and the second pawl 154 are opposite, for example, when the first pawl 132 rotates clockwise, the second pawl 154 rotates counterclockwise, which is beneficial to realizing that the first pawl 132 and the second pawl 154 are respectively separated from the ratchet wheel 12 under the condition that the shift fork 13 rotates at a small angle, and is beneficial to reducing the rotation range of the shift fork 13 and the shift block 14, so that the space occupation of the clutch assembly 100 is reduced, and the shift fork 13 can be saved, The space between the shift block 14 and the ratchet 12 allows the clutch assembly 100 to be more compact.

According to the clutch assembly 100 provided by the embodiment of the invention, the rotation of the shift fork 13 can 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 matched with or separated from the ratchet wheel 12, the shift fork 13 and the shift block 14 are separately arranged, when the shift fork 13 rotates, the rotation direction of the shift block 14 is opposite to that of the shift fork 13, so that the rotation directions of the first pawl 132 and the second pawl 154 are opposite, the first pawl 132 and the second pawl 154 are respectively separated from the ratchet wheel 12 under the condition that the shift fork 13 rotates by a small angle, the rotation range of the shift fork 13 and the shift block 14 is favorably 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 respectively provided with a first pivot portion 131 and a first pawl 132, the first pivot portion 131 is disposed at a distance from the first pawl 132 in the circumferential direction of the ratchet wheel 12, the dial 14 is located on one side of the first pawl 132 adjacent to the first pivot portion 131 and extends in the circumferential direction of the ratchet wheel 12, the one end of the dial 14 is provided with a second pivot portion 141, and the first pivot portion 131 and the second pivot portion 141 are rotatably and movably connected. Therefore, the shifting fork 13 and the shifting block 14 can be connected in a rotatable mode, the structure is simple, and machining and forming are facilitated.

Further, as shown in 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 through the shift block 14, and the first pivot hole extends in a long bar 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 can be understood that the area of the first pivot hole is larger than that of the first pivot shaft, so that there is a moving and rotating allowance between the first pivot part 131 and the second pivot part 141, which facilitates the rotatable and movable connection of the first pivot part 131 and the second pivot part 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 disposed 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 to the housing 11, a fifth pivot portion 142 is disposed on the dial 14, and the fifth pivot portion 142 is rotatably and movably connected to the fourth pivot portion 152; wherein the second pawl 154 is immovably arranged on the turning block, in other words, the second pawl 154 is fixedly connected to the turning block. Therefore, when the shifting fork 13 drives one end of the shifting block 14 to rotate relative to the other end of the shifting block 14, the rotating block 15 rotates around the rotation center line of the third pivot part 151, so that the rotation track of the second pawl 154 can be formed into an arc line, which is beneficial to improving the working reliability of the second pawl 154. For example, the third pivot portion 151 is formed as a pivot shaft, and the housing 11 is provided with a pivot hole to be engaged with the third pivot 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 on the dial 14, and the second pivot hole extends in a long bar shape along the circumferential direction of the ratchet 12. It is understood that the area of the second pivot hole is larger than that of the second pivot shaft, so that there is a moving and rotating allowance between the fourth pivot part 152 and the fifth pivot part 142, which facilitates the fourth pivot part 152 and the fifth pivot part 142 to be rotatably and movably connected.

For example, as shown in fig. 6, the rotating block 15 is further provided with a sixth pivoting portion 153, the sixth pivoting portion 153 and the third pivoting 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 pivoting portion 153 and the third pivoting portion 151 are located on the same straight line, the dial block 14 is further provided with a seventh pivoting portion 143, the seventh pivoting portion 143 is rotatably and movably connected with the fourth pivoting portion 152, the seventh pivoting portion 143 is formed as a pivoting hole and extends into a long strip shape along the radial direction of the ratchet 12, the seventh pivoting portion 143 is communicated with the fifth pivoting portion 142, the hole depth of the seventh pivoting portion 143 is greater than that of the fifth pivoting portion 142, and the length of the fourth pivoting portion 152 is greater than that of the sixth pivoting portion 153, so as to facilitate preventing the fourth pivoting portion 152 from sliding into the seventh pivoting portion 143 from the fifth pivoting portion 142, and to ensure the working reliability 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 immovably disposed 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 151 is rotatably connected to the fixed block 16. It can be understood that the shifting block 14 is rotatably connected with the housing 11 through the fixed block 16, and the rotating block 15 is rotatably connected with the housing 11 through the fixed block 16, so that it is not necessary to additionally machine a structure on the housing 11 to respectively cooperate with the shifting block 14 and the rotating block 15, which is beneficial to 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 is disposed on one axial side of the housing 11 and disposed around the ratchet 12, and the fixing block 16 is disposed on the stator 18. For example, as shown in fig. 2, the stator 18 is formed in an annular shape, the top end of the stator 18 is provided with an inward turned flange 146 portion, the stator 18 is connected to one axial side of the housing 11 through the flange 146 portion, the fixed block 16 is provided on the flange 146 portion, the peripheral wall of the stator 18 is provided with an avoidance hole 181, one end of the shift fork 13 provided with the first pawl 132 extends into the stator 18 through the avoidance hole 181, and the fixed block 16, the rotating block 15, and the shift block 14 are located between the ratchet 12 and the inner peripheral wall of the stator 18 (see fig. 4). Therefore, the stator 18 of the motor is directly arranged on the shell 11, and the ratchet wheel 12 is positioned on the inner side of the stator 18, so that the space occupation of the clutch assembly 100 is further reduced.

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

According to the clutch assembly 100 of the embodiment of the invention, the rotation of the shift fork 13 can 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 matched with or separated from the ratchet wheel 12, and it can be understood that the shift fork 13 and the shift block 14 of the invention are separately arranged, when the shift fork 13 rotates, the rotation direction of the shift block 14 is opposite to that 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 realizing that the first pawl 132 and the second pawl 154 are separated from the ratchet wheel 12 under the condition that the shift fork 13 rotates by a small angle, and can reduce the rotation range of the shift fork 13 and the shift block 14, so that the clutch assembly 100 of the embodiment of the invention can be suitable for the condition that the opening of the stator 18 is limited.

The driving mechanism 400 of the laundry treating apparatus according to the embodiment of the present invention will be described with reference to fig. 10 to 18.

As shown in fig. 12 and 13, according to the power transmission mechanism 400 of the laundry treating apparatus according to the embodiment of the present invention, the power transmission mechanism 400 includes the first moving member 42 and the second moving member 43. Specifically, when the power transmission mechanism 400 is applied to the laundry treating apparatus, in order to enable the function of the power transmission mechanism 400, as shown in fig. 10 and 11, the laundry treating apparatus further includes a power unit, a first performing unit, and a second performing unit.

As shown in fig. 10 and 12, the first moving element 42 is adapted to be connected to the power unit 200 and move in a first direction (e.g., left and right directions shown in fig. 12) under the driving of the power unit 200, the first moving element 42 moves to drive the first manipulating element of the first executing unit to move, the second moving element 43 is connected to the first moving element 42, the second moving element 43 is adapted to be connected to the second manipulating element of the second executing unit, and the second moving element 43 can drive the second manipulating element to move under the driving of the first moving element 42.

In the following description, the first actuator unit is the clutch assembly 100 mentioned above, the first operating member is the shift lever 178, the second actuator unit is the drain valve 300 mentioned above, and the second operating member is the return spring 31, for example, wherein the power unit 200 may be a two-stroke retractor having the traction rope 21.

As shown in fig. 16, 17 and 18, the movement of the first mover 42 in the moving direction of the first mover 42 includes a first stroke and a second stroke. Specifically, for example, during the movement from right to left, the first moving element 42 moves first by a first stroke and then by a second stroke.

In the first stroke, the first moving member 42 is movable with respect to the second moving member 43, and the second moving member 43 is not moved, in which state the lever 178 swings, the drain valve 300 is closed, and the laundry treating apparatus is in the hand washing mode; in the second stroke, the first moving member 42 continues to move and drives the second moving member 43 to move synchronously, and in this state, the shift lever 178 continues to swing while the drain valve 300 is opened, and the laundry treatment apparatus is in the dehydration mode, thereby enabling the switching of the plurality of operation modes of the laundry treatment apparatus.

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

Specifically, for example, referring to fig. 10 and 16, when the transmission mechanism 400 is in the initial state (i.e., the first moving member 42 has not yet started to move for the first stroke), 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 shift lever 178, the second moving member 43 is connected to the first moving member 42, and the second moving member 43 is connected to the drain valve 300, at which time the power unit 200 is powered off and does not operate, the first moving member 42 does not move, and thus the shift lever 178 and the second moving member 43 do not move. In this state, with the clutch assembly 100, the brake band is in a locked state, 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 cartridge of the drain valve 300 is in a closed position, the drain valve 300 does not drain, and the laundry treating apparatus may be in a normal washing mode.

Referring to fig. 17, when the power unit 200 starts to operate, the traction rope 21 starts to pull the first moving member 42 to move leftward for a first stroke, in which the first moving member 42 only drives the shift lever 178 to swing and the second moving member 43 still does not move. In this state, for the clutch assembly 100, the lever 178 drives the brake band to move such that the brake band no longer locks the brake disc 173, the brake disc 173 is in a free state, and the first pawl 132 and the second pawl 154 are still engaged with the ratchet 12, thereby enabling the inner tub of the laundry treating apparatus to be in a free state, the pulsator to be in a rotating state, and the inner tub to be driven to rotate by water current after the pulsator rotates; as for the drain valve 300, the valve core of the drain valve 300 is still in the closed position, the drain valve 300 does not drain water, and at this time, the laundry treating apparatus is in the hand washing mode.

Referring to fig. 18, when the power unit 200 continues to operate, the traction rope 21 continues to pull the first moving element 42 to move leftward for a second stroke, and at the second stroke, the first moving element 42 drives the shift lever 178 to swing continuously and also drives the second moving element 43 to move leftward. In this state, the brake disc 173 is still in a free state for the clutch assembly 100, and the shift lever 178 abuts against the adjustment screw and forces the shift fork 13 to rotate by the adjustment 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; for the water discharge valve 300, after the second moving member 43 moves to the left, the return spring 31 connected to the second moving member 43 is stretched, and when the acting force of the return spring 31 is greater than that of the outer spring, the return spring 31 will pull the valve core to move to the open position to discharge water from the water discharge valve 300, and at this time, the laundry treatment apparatus is in the dehydration mode.

When the power unit 200 is not operated, the power unit 200 is powered off, the traction rope 21 does not generate pulling force on the first moving part 42 any more, at this time, the shift lever 178 starts to reset under the action of the shift lever torsion spring, and simultaneously, the first moving part 42 and the second moving part 43 move rightwards and reset to the initial state under the driving of the reset spring 31 and the shift lever 178 because the second moving part 43 is connected with the reset spring 31 of the drain valve 300.

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 43 can be moved at a specific position and time to adjust the working states of the first execution unit and the second execution unit, thereby realizing adjustment of the working modes of the laundry treatment apparatus to meet different washing requirements of users, and compared with the related art in which the clutch assembly 100 is controlled independently and the drain valve 300 is controlled independently, this form is beneficial to simplifying the overall structure of the laundry treatment apparatus and reducing the operation cost.

According to the transmission mechanism 400 of the clothes treatment apparatus of the embodiment of the present invention, the driving action of the power unit 200 can be distributed, so that the first moving part 42 can be moved at a specific position and time or both the first moving part 42 and the second moving part 43 can be moved to adjust the working states of the first execution unit and the second execution unit, thereby realizing the adjustment of the working modes of the clothes treatment apparatus to meet different washing requirements of users, which is beneficial to simplifying the overall structure of the clothes treatment apparatus and reducing the operation cost.

In some embodiments of the present invention, as shown in fig. 16, 17 and 18, the transmission mechanism 400 includes a first transmission portion and a second transmission portion, the first transmission portion is disposed on the first moving member 42, the second transmission portion is disposed on the second moving member 43, and the second transmission portion cooperates with the first transmission portion to drive the second moving member 43 to move in the second stroke, so that the structure is simple.

In some embodiments of the present invention, as shown in fig. 13 and 15, the transmission mechanism includes a mounting base 41, the mounting base 41 has a mounting cavity 411, one end of the mounting base 41 in the first direction (for example, the left-right direction) has a first opening 4111 communicating with the mounting cavity 411, and the other end of the mounting base 41 in the first direction has a second opening 4112 communicating with the mounting cavity 411, so that the structure is simple.

Specifically, for example, referring to fig. 14 and 16, the left end of mounting base 41 has first opening 4111, first opening 4111 communicates with mounting cavity 411, the right end of mounting base 41 has second opening 4112, and second opening 4112 communicates with mounting cavity 411. In practice, the mounting seat 41 is generally immovably installed in the cabinet 500 of the laundry treating apparatus.

As shown in fig. 12, at least a portion 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., left-right direction) with respect to the mounting base 41. It is understood that, during the movement of the first moving member 42, the first moving member 42 may be always located in the mounting cavity 411; alternatively, the movement of the first moving member 42 has two extreme positions, when the first moving member 42 is located at one of the extreme positions, the first moving member 42 is located in the mounting cavity 411, and when the first moving member 42 is located at the other extreme position, the first moving member 42 is partially located in the mounting cavity 411; or, during the moving process of the first moving element 42, the first moving element 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 element 42.

As shown in fig. 11 and 12, the first mover 42 is adapted to be coupled to a first actuator of the first actuator, such as a toggle lever 178 of the clutch assembly 100. In practical applications, for example, the portion of the first moving element 42 exposed from the mounting cavity 411 is connected to the shift lever 178; or, an avoiding opening 416 communicated with the mounting cavity 411 is formed in the peripheral wall of the mounting seat 41, and the shift lever 178 passes through the avoiding opening 416 to be connected with the first moving member 42 in the mounting cavity 411, of course, the first moving member 42 and the shift lever 178 may be connected in other manners, which is not limited in the present invention.

As shown in fig. 10, 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 may be connected to the power unit 200 after penetrating out of the first opening 4111 and being located outside the mounting cavity 411, or the power unit 200 may be inserted into the mounting cavity 411 or the power unit 200 may be connected to one end of the first moving member 42 by being inserted into the mounting cavity 411 through another connection member.

In practical applications, for example, one end of the first moving member 42 may protrude outside 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 connect with one end of the first moving member 42, however, the first moving member 42 and the shift lever 178 may be connected in other manners, which is not limited in the present invention.

As shown in fig. 12, at least a portion of the second mover 43 is located in the mounting cavity 411, and the second mover 43 is movable in the first direction with respect to the mount 41. It is understood that, during the movement of the second mover 43, the second mover 43 may be always located in the installation cavity 411; alternatively, the movement of the second moving member 43 has two extreme positions, when the second moving member 43 is located at one of the extreme positions, the second moving member 43 is located in the mounting cavity 411, and when the second moving member 43 is located at the other extreme position, the second moving member 43 is partially located in the mounting cavity 411; alternatively, during the movement of the second moving member 43, the second moving member 43 is always partially located in the mounting cavity 411. The mounting cavity 411 can thus provide a certain protection for the second mover 43.

The second moving member 43 is connected to the first moving member 42 and is relatively movable in the first direction, that is, the second moving member 43 is movable relative to both the mounting base 41 and the first moving member 42, and similarly, the first moving member 42 is movable relative to the second moving member 42.

As shown in fig. 10 and 13, one end of the second moving member 43 is adapted to be connected to a second control member (e.g., the drain valve 300) through a second opening 4112. For example, it may be that one end of the second moving member 43 protrudes to the outside of the mounting chamber 411 through the second opening 4112 to be connected to one end of the return spring 31 (e.g., the free end of the return spring 31 as described above) of the water discharge valve 300; or one end of the return spring 31 of the water discharge valve 300 (e.g., the free end of the return spring 31 described above) protrudes into the mounting chamber 411 through the second opening 4112 to be connected to the second moving member 43.

In some embodiments of the present invention, as shown in fig. 13, a side wall surface of the mounting cavity 411 in the second direction (e.g., up-down direction) is provided with a plurality of first teeth portions 412, and the plurality of first teeth portions 412 are arranged in the first direction. Specifically, for example, referring to fig. 14, a plurality of first tooth portions 412 are provided on a lower wall surface of the mounting cavity 411, and the plurality of first tooth portions 412 are arranged in the left-right direction, so that a rack-like structural form can be formed, the structure is simple, and the implementation is convenient.

As shown in fig. 13, the first transmission portion is a gear 44, the gear 44 is rotatably connected to the first moving member 42 and is located on a side of the first moving member 42 close to the second opening 4112 (for example, a right side of the first moving member 42), so that when the first moving member 42 moves, the first moving member 42 can further drive the gear 44 to move, a rotation center line of the gear 44 extends along a third direction (for example, a front-back direction), wherein the first direction, the second direction and the third direction are perpendicular to each other, the gear 44 is located between the first tooth portion 412 and the second moving member 43 along the second direction, the second transmission portion is a plurality of second tooth portions 431 disposed on the second moving member 43, and the plurality of second tooth portions 431 are arranged along the first direction.

Specifically, for example, referring to fig. 16, the gear 44 is located below the second moving member 43 and above the first tooth portion 412, a plurality of second tooth portions 431 are provided on a lower sidewall of the second moving member 43, and the plurality of second tooth portions 431 are arranged in the left-right direction, so that a rack-like structure can be formed, and the second tooth portions 431 are engaged with the gear 44.

Further, as shown in fig. 16, in the first stroke, the gear 44 is engaged with the second tooth portion 431 and the gear 44 is not engaged with the first tooth portion 412, and the first tooth portion 412 is located between the gear 44 and the first opening 4111 in the first direction.

Specifically, for example, referring to fig. 16, in the initial state, the first tooth portion 412 is located on the left side of the gear 44 with a space from the gear 44; when the first moving element 42 moves leftwards for a first stroke, the first moving element 42 drives the gear 44 to move leftwards, and since the gear 44 is only meshed with the second tooth 431 at this time, under the meshing force, the gear 44 rotates clockwise and applies a leftward driving force to the second moving element 43, and at the same time, under the traction of the return spring 31, the second moving element 300 does not move.

Further, as shown in fig. 18, at the second stroke, the gear 44 is simultaneously in meshing engagement with the first tooth portion 412 and the second tooth portion 431.

Specifically, for example, referring to fig. 18, when the first mover 42 has moved the first stroke and starts moving leftward for the second stroke, the first moving member 42 will still drive the gear 44 to move leftwards, at this time, the gear 44 still engages with the second tooth portion 431, and the rightmost first tooth portion 412 begins to enter the tooth slot of the gear 44 to mesh with the gear 44, in the next second stroke, therefore, the gear 44 will simultaneously mesh with the first tooth 412 and the second tooth 431, in this state, since the first tooth portion 412 is located on the immovable mount 41, and the second tooth portion 431 is located on the second moving member 43 movable relative to the mount 41, therefore, the gear 44 moves leftward and rotates counterclockwise, and the counterclockwise rotation of the gear 44 applies a leftward force to the second moving member 431, so as to drive the second moving member 43 to move leftward and open the drain valve 300.

Therefore, the second moving part 43 can move only in the second stroke through the structural form that the gear 44 is only meshed with the second tooth part 431 in the first stroke and the gear 44 is simultaneously meshed with the first tooth part 412 and the second tooth part 431 in the second stroke, and the transmission form similar to a gear rack has the advantages of simple structure, large transmission power, smooth transmission and high reliability.

It is understood that, in addition to the above-mentioned structural forms, there are many structural forms that can realize the second moving member 43 moving only in the second stroke by the first moving member 42, and the present invention is not limited thereto.

In practical applications, as shown in fig. 16 and 17, since the shape and size of the gear 44, the specific values of the first stroke and the second stroke, and the like may affect the rotation angle of the gear 44, there may be a case where teeth in a partial region of the outer circumferential wall of the gear 44 are not engaged with the first tooth portion 412 nor with the second tooth portion 431 during the first stroke and the second stroke, and thus, in order to reduce the use of material for the gear 44 and to improve the compactness of the overall structure, teeth may not be provided in the partial region of the gear 44.

In some embodiments of the present invention, considering that the return spring 31 is generally a spring with a pull ring at one end (i.e., a free end) in practical application, so as to facilitate the connection of the second moving member 43 with the return spring 31, as shown in fig. 16, the right end of the second moving member 43 is provided with a mounting hole 432, so that the pull ring of the return spring 31 can be inserted into the mounting hole 432.

Further, in order to make the second moving element 43 not easily shake, the return spring 31 may have a certain pre-tightening force, for example, referring to fig. 16, when the transmission mechanism 400 is in the initial state, the return spring 31 is already in the stretched state, so that the pre-tightening force may be generated, and the pre-tightening force makes the second moving element 43 abut against the valve cover 32 of the drain valve 300 located at the right side of the second moving element 43.

In some embodiments of the present invention, as shown in fig. 15, 16 and 18, a side wall of the mounting seat 41 opposite to the first tooth portion 412 (for example, an upper side wall of the mounting seat 41) is provided with a limiting hole 413 communicating with the mounting cavity 411, a surface of the second moving member 43 facing the limiting hole 413 (for example, an upper surface of the second moving member 43) is provided with a stop rib 433, the stop rib 433 is located in the limiting hole 413, the limiting hole 413 has a first wall surface 4131 and a second wall surface 4132 opposite to each other along the first direction, the first wall surface 4131 is located between the first opening 4111 and the second wall surface 4132, the stop rib 433 abuts against the second wall surface 4132 when the first stroke and the power unit 200 are not operated, and the stop rib 433 abuts against the first wall surface 4131 at the end of the second stroke, so that the stop rib 433 can limit the second moving member 43.

Specifically, for example, referring to fig. 16, 17, and 18, the stopper hole 413 has a first wall surface 4131 and a second wall surface 4132 opposed to each other in the left-right direction, in which the first wall surface 4131 is located on the left side and the second wall surface 4132 is located on the right side; when the transmission mechanism 400 is in the initial state, the power unit 200 is powered off and does not work, the stop rib 433 abuts against the second wall surface 4132 under the pretightening force of the return spring 31, and the second moving member 43 does not move; in the process of the first stroke, since the gear 44 rotates clockwise, the force between the gear 44 and the second tooth portion 431 causes the abutting rib 433 to still abut against the second wall surface 4132, and thus the second moving member 43 still does not move; in the process of the second stroke, because the gear 44 rotates counterclockwise, the gear 44 drives the second moving member 43 to move leftward, the stop rib 433 moves leftward along with the second moving member 43, at the final stage of the second stroke, the stop rib 433 abuts against the first wall surface 4131, and at this time, the second moving member 43 cannot move continuously, so that after the stop rib 433 is arranged, the moving stroke of the second moving member 43 can be limited, and the second moving member 43 can be prevented from moving excessively, so that the reset spring 31 cannot be reset due to overextension.

Optionally, as shown in fig. 14, 16, and 18, the stop rib 433 includes a first rib plate 4331 and a second rib plate 4332, the first rib plate 4331 extends along a third direction (e.g., a front-back direction), the second rib plate 4332 is respectively disposed at two opposite ends of the first rib plate 4331 along the third direction, the second rib plate 4332 extends along the first direction (e.g., a left-right direction), the second rib plate 4332 is located at a side of the first rib plate 4331 close to the first wall surface 4131, the first rib plate 4331 abuts against the second wall surface 4132 when the first stroke and the power unit 200 do not operate, and the second rib plate 4332 abuts against the first wall surface 4131 at the end of the second stroke, so that the stop rib 433 has a higher structural strength.

Specifically, referring to fig. 13, the first rotating portion 420 is a pivot hole, and the second rotating portion 441 is a pivot shaft.

In some embodiments of the present invention, as shown in fig. 15, a first guiding step portion 4141 is provided on a surface of the first protrusion 414 away from the first tooth portion 412 in the second direction, a second guiding step portion is provided on a surface of the second protrusion 415 away from the first tooth portion 412 in the second direction, and the first moving member 42 is fitted between the first guiding step portion 4141 and the second guiding step portion, whereby the first guiding step portion 4141 and the second guiding step portion can guide the first moving member 42 to prevent the first moving member 42 from being displaced.

In some embodiments of the present invention, the first moving element 42 moves a distance d1 in the first stroke, and d1 has a value in the range of 15-25 mm.

Specifically, when the transmission mechanism 400 is actually applied to the clothes processing apparatus, the moving distance d1 of the first stroke of the first moving member 42 needs to be taken as a value within a reasonable range, if d1 is smaller, the swing amplitude of the shift lever 178 is smaller under the driving action of the first stroke of the first moving member 42, so that the shift lever 178 may not effectively shift and loosen the brake band to enable the brake disc 173 to be in a free state, and if d1 is larger, the size of the transmission mechanism 400 in the left-right direction is larger, so that the occupied space of the transmission mechanism 400 is larger, and the transmission mechanism 400 is not easy to install.

Specifically, when the transmission mechanism 400 is actually applied to the clothes treatment apparatus, the moving distance d2 of the second stroke of the first moving member 42 needs to be taken within a reasonable range, if d2 is smaller, the swing amplitude of the shift lever 178 is smaller under the driving action of the second stroke of the first moving member 42, so that the shift lever 178 may not effectively shift the shift fork 13, so that the first pawl 132 and the second pawl 154 are completely disengaged from the ratchet 12, and if d2 is larger, the size of the transmission mechanism 400 in the left-right direction is larger, so that the occupied space of the transmission mechanism 400 is larger, and the installation of the transmission mechanism 400 is not easy.

In some embodiments of the present invention, as shown in fig. 13 and 14, the peripheral wall of the mounting seat 41 is provided with an avoiding opening 416 communicating with the mounting cavity 411, and the first operation member (e.g., the shift lever 178) passes through the avoiding opening 416 to be connected to the first moving member 42, so that the structure is simple.

Specifically, an escape opening 416 communicating with the mounting cavity 411 is provided on a side wall of the mounting seat 41 in the third direction. For example, referring to fig. 12 and 13, an avoiding opening 416 is formed in a front side wall of the mounting seat 41, the avoiding opening 416 is substantially rectangular, the avoiding opening 416 is communicated with the mounting cavity 411, a positioning through hole 427 is formed in the first moving member 42, the positioning through hole 427 extends in the front-back direction, the positioning through hole 427 is always communicated with the avoiding opening 416, and the shift rod 178 passes through the avoiding opening 416 and extends into the positioning through hole 427 and is matched with the positioning through hole 427, so that when the first moving member 42 moves leftward, the first moving member 42 can push the shift rod 178 to swing, and the connection form does not need an additional connecting member, and is simple in structure and 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 with the first moving member 42, as shown in fig. 13, 14 and 16, a positioning groove 428 is provided on the first moving member 42, a first positioning opening 42a is provided on a side wall of the first moving member 42 facing the first opening 4111 (for example, a left side wall of the first moving member 42), a second positioning opening 42b is provided on one of two side walls of the first moving member 42 opposite in the third direction (for example, a rear side wall of the first moving member 42), both the first positioning opening 42a and the second positioning opening 42b are communicated with the positioning groove 428, and furthermore, the first positioning opening 42a is communicated with the second positioning opening 42 b.

Specifically, in practical applications, the power unit 200 used in the clothes treating apparatus is generally provided with a connector at one end of the pulling rope 21, so that when the clothes treating apparatus is installed, the connector can extend into the positioning groove 428 through the second positioning opening 42b, the pulling rope 21 is inserted into the first positioning opening 42a, and then the position of the first moving member 42 is adjusted to make the connector abut against the left side wall of the positioning groove 428, so that when the power unit 200 works, the pulling rope 21 can conveniently pull the first moving member 42 to move leftward, and this connection form does not need an additional connector, and is simple in structure and convenient to assemble.

In some embodiments of the present invention, as shown in fig. 12, the mounting base 41 is detachably installed in the cabinet 500, thereby facilitating the assembly and disassembly of the mounting base 41. There are many ways to achieve detachable connection, for example, the mounting base 41 and the casing 500 can be detachably connected through a connecting member such as a bolt, and this connection form is convenient to install and reliable in connection; or, the mounting base 41 is connected with the casing 500 through a buckle, the mounting base 41 is provided with a plurality of clamping buckles, and the casing 500 is provided with a plurality of clamping grooves which are matched with the clamping buckles in a one-to-one correspondence manner, so that the mounting base 41 and the casing 500 can be reliably and tightly fixed through the matching clamping of the clamping buckles and the clamping grooves, the assembling process is simple, and which mode is adopted can be flexibly selected according to actual production, assembling conditions and the like, and the invention is not limited to this.

In practical applications, when the mounting seat 41 cannot be mounted on the cabinet 500 due to factors such as the internal space of the laundry treating apparatus and the size of each part, the mounting seat 41 may be further mounted on the valve cover 32 of the water discharge valve 300 and detachably connected to the valve cover 32, or mounted on the housing of the power unit 200 and detachably connected to the housing.

A control method of a laundry treating apparatus according to an embodiment of the present invention is described below with reference to fig. 19 and 20.

As shown in fig. 19, the laundry treating apparatus has a hand wash washing mode and a regular washing mode, and the control method includes the steps of:

s1: the washing mode selected by the user is judged. In the specific application, the clothes treatment equipment is started up firstly, then a user selects a washing mode in advance through keys or knobs and the like on the clothes treatment equipment according to factors such as the dirt degree of clothes, the fabric type and the like, and finally a controller of the clothes treatment equipment judges whether the user selects a conventional washing mode or a hand scrubbing mode through the operation of the user.

S2: when the normal washing mode is selected, the power unit 200 does not operate, the inner tub does not rotate and the pulsator rotates. Specifically, when the controller determines that the user selects the normal washing mode, the controller does not activate the power unit 200 for the power unit 200, and the power unit 200 does not operate; for the transmission mechanism 400, the transmission mechanism 400 is in the initial state, and the first moving member 42 does not move; with the clutch assembly 100, the brake band is in a locked state, the first pawl 132 and the second pawl 154 are engaged with the ratchet 12, thereby immobilizing the inner tub of the laundry treating apparatus and allowing the pulsator to rotate; as for the water discharge valve 300, the water discharge valve 300 does not discharge water, and the laundry treating apparatus is in the normal washing mode at this time.

When the hand scrubbing mode is selected, the first moving member 42 is in the first stroke, the pulsator rotates and the inner tub is rotated by the water current. Specifically, when the controller determines that the user selects the hand washing mode, as for the power unit 200, the controller starts to activate the power unit 200, and the power unit 200 starts to operate; for the transmission mechanism 400, the traction rope 21 of the power unit 200 pulls the first moving member 42 to move for the first stroke action; for the clutch assembly 100, the first mover 42 drives the shift lever 178 to swing to shift the brake band loose, while the first pawl 132 and the second pawl 154 are still engaged with the ratchet 12, thereby rotating the pulsator and driving the inner tub to rotate by the water current; with respect to the water discharge valve 300, the water discharge valve 300 does not discharge water, and at this time, the laundry treating apparatus operates in the hand washing mode, when the first mover 42 moves to the end of the first stroke, the controller controls the power unit 200 to stop pulling the traction rope 21, and the traction rope 21 remains still, or the controller determines the washing time selected by the user, and controls the traction speed of the power unit 200 according to the washing time so that the controller controls the first mover 42 to just end the first stroke at the end of the washing.

S3: after the washing is finished, the first mover 42 is in the second stroke, and the dehydrating mode is operated.

Specifically, for the normal washing mode, when the total washing time a of the laundry treating apparatus reaches the preset time, the controller judges that the normal washing mode is ended and starts the dehydrating mode, and at this time, for the power unit 200, the controller starts to activate the power unit 200 and the power unit 200 starts to operate; for the transmission mechanism 400, the traction rope 21 of the power unit 200 pulls the first moving member 42 to move and rapidly finishes the first stroke and then continues to move to be in the second stroke; for the clutch assembly 100, the first moving element 42 drives the shift lever 178 to swing, and the shift lever 178 firstly releases the brake band and then shifts the shift fork 13 to disengage the first pawl 132 and the second pawl 154 from the ratchet wheel 12, so that the pulsator and the inner tub synchronously rotate; with the water discharge valve 300, the second mover 43 starts to move and causes the water discharge valve 300 to be opened, at which time the laundry treating apparatus is in the dehydration mode.

For the hand rubbing mode, when the total washing time b of the laundry treating apparatus reaches the preset time, the controller judges that the hand rubbing mode is finished and starts the dehydration mode, and at this time, for the power unit 200, the controller controls the power unit 200 to continuously pull the traction rope 21; for the transmission mechanism 400, the traction rope 21 pulls the first motion member 42 to move continuously at the second stroke; for the clutch assembly 100, the first moving element 42 drives the continuous shift lever 178 to swing, and the shift lever 178 continuously shifts the shifting fork 13 to disengage the first pawl 132 and the second pawl 154 from the ratchet wheel 12, so that the pulsator and the inner tub synchronously rotate; with the water discharge valve 300, the second mover 43 starts to move and causes the water discharge valve 300 to be opened, at which time the laundry treating apparatus is in the dehydration mode.

Here, it can be understood that when the first mover 42 moves to the end of the second stroke, the controller controls the power unit 200 to stop pulling the traction rope 21, the traction rope 21 remains stationary to maintain the dehydration mode, or the controller judges the dehydration time selected by the user, controls the traction speed of the power unit 200 according to the dehydration time to control the first mover 42 to just end the second stroke at the end of the dehydration.

When the dehydration mode is finished, the controller no longer controls the power unit 200, the power unit 200 is powered off, the traction rope 21 no longer generates tension on the first moving element 42, and the transmission mechanism 400 is reset under the action of the driving lever 178 and the reset spring 31 of the drain valve 300.

According to the control method of the laundry treating apparatus of the embodiment of the present invention, the driving action of the power unit 200 can be distributed, so that the first moving member 42 can be moved at a specific position and time or both the first moving member 42 and the second moving member 43 can be moved to adjust the operating states of the first and second performing units, thereby not only facilitating the rapid and convenient adjustment of the laundry treating apparatus in the normal washing mode and the hand washing mode to meet different washing requirements of a user, but also having a simple and convenient control process and being easy to implement.

In some embodiments of the present invention, as shown in fig. 20, the laundry treating apparatus further has a hybrid washing mode.

In the above step S2, when the hybrid washing mode is selected, the power unit 200 is first deactivated for t1 minutes without the inner tub being rotated and the pulsator being rotated; after t1 minutes, the first moving element 42 is in the first stroke, the pulsator rotates and the inner tub is driven to rotate by the water current.

Specifically, when the controller determines that the hybrid washing mode is selected by the user, the controller does not activate the power unit 200 for t1 minutes, so that the power unit 200 does not operate for t1 minutes to perform the normal washing mode, and during this time, the operation states of the power unit 200, the transmission mechanism 400, the clutch assembly 100 and the drain valve 300 are the same as those of the above-mentioned laundry treating apparatus in the normal washing mode, and thus, the detailed description thereof is omitted; after t1 minutes, the hand washing mode is performed, and the controller starts to activate the power unit 200, and during the next t2 minutes, the operation states of the power unit 200, the transmission mechanism 400, the clutch assembly 100 and the drain valve 300 are the same as those of the above-mentioned laundry treating apparatus in the hand washing mode, and thus the detailed description thereof is omitted. It can be seen that, in the hybrid washing mode, the laundry treating apparatus may combine the washing advantages of the conventional washing mode and the hand washing mode, which is advantageous for achieving a washing effect of low abrasion and high washing ratio. In practical applications, the specific time of t1 and the specific time of t2 can be set according to washing requirements, but the invention is not limited thereto, for example, t1 can be 5-60 minutes, and t2 can be 1-10 minutes.

When the total washing time of the hybrid washing mode exceeds the preset time t3, the controller determines that the hybrid washing mode is finished and starts the dehydration mode, and during this time, the operating states of the power unit 200, the transmission mechanism 400, the clutch assembly 100 and the drain valve 300 are the same as the operating state of the dehydration mode of the laundry treating apparatus after the hand washing mode, and thus, the detailed description thereof is omitted.

According to the control method of the laundry treating apparatus of the embodiment of the present invention, the driving motion of the power unit 200 can be distributed, so that the first moving member 42 can be moved at a specific position and time or both the first moving member 42 and the second moving member 43 can be moved to adjust the operating states of the first and second execution units, thereby conveniently implementing the hybrid washing mode of the laundry treating apparatus, and thus, the washing advantages of the conventional washing mode and the hand washing mode can be combined, which is beneficial for achieving the washing effect of low abrasion and high washing ratio, and the control process is simple and convenient and is easy to implement.
