Detailed Description

The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

The individual features described in the specific embodiments can be combined in any suitable manner, without contradiction, for example by combination of different specific features, to form different embodiments and solutions. Various combinations of the specific features of the invention are not described in detail in order to avoid unnecessary repetition.

As shown in fig. 1, a transmission mechanism 1 provided in an embodiment of the present invention may provide driving forces for a first object and a second object, so that the driving forces can be transmitted to the first object and the second object as required under the transmission action of the transmission mechanism, so that the first object and the second object can perform asynchronous movement according to the movement requirement, and perform corresponding control functions. The first object and the second object are external members capable of performing a predetermined function by obtaining the driving force of the transmission mechanism 1. If it is applied to the pulsator washing machine, the first object may be a drain assembly, and the second object may be a clutch. The action of the drain assembly for controlling the drain function and the action of the clutch for controlling the washing function do not need to synchronously move, so that the function of asynchronous movement of the drain assembly and the clutch can be realized through the transmission mechanism 1. That is, when the clutch is moved, the washing of the laundry is achieved while the corresponding control function can be performed. The clutch stops moving, the position after the movement is kept unchanged, and then the opening and the drainage of the drainage assembly can be realized by executing the action of moving the drainage assembly.

As shown in fig. 1 and 2, the transmission mechanism 1 includes a bracket body 11, a slide rail 12, a first link 13, a carriage 14, and a switching structure 15. The position of the bracket body 11 will not change after installation, a sliding groove 111 is formed in the bracket body 11, and the sliding rail 12 is arranged in the sliding groove 111 and can reciprocate in the sliding groove 111. The first connecting piece 13 is movably connected to the sliding rail 12 and moves along with the sliding rail 12 as required, the first connecting piece 13 is used for connecting a first object to drive the first object to move, and a moving buffer distance is arranged between the first connecting piece 13 and the sliding rail 12 so as to enable the sliding rail 12 not to immediately drive the first connecting piece 13 to move when moving. The sliding frame 14 is arranged between the sliding rail 12 and the bracket body 11, and moves along with the sliding rail 12 according to requirements, and the sliding frame 14 is used for connecting a second object so as to drive the second object to move. The switching structure 15 is disposed between the bracket body 11, the sliding frame 14 and the sliding rail 12, and the switching structure 15 is used for switching the synchronous movement of the second object following the sliding rail 12 into the synchronous movement of the first object following the sliding rail 12. Specifically, the switching structure 15 can lock the sliding rail 12 and the sliding frame 14 to move synchronously, and can disengage the transmission between the sliding rail 12 and the sliding frame 14 after the sliding frame 14 moves synchronously along with the sliding rail 12 for a preset distance, so that the sliding frame 14 does not move synchronously along with the sliding rail 12. In this way, when the traction device is used to pull the sliding rail 12 to move, the sliding frame 14 and the sliding rail 12 are synchronously moved under the connection action of the switching structure 15, so that the second object connected with the sliding frame 14 obtains the driving force to move. Because the first connecting piece 13 and the sliding rail 12 have a moving buffer distance, before the sliding frame 14 and the sliding rail 12 synchronously move for a stroke of moving buffer distance, the sliding rail 12 does not drive the first connecting piece 13 to move, and therefore, a first object connected with the first connecting piece 13 is not driven to move. After the carriage 14 and the slide rail 12 move synchronously with respect to the bracket body 11 by a travel of a movement buffer distance, the movement transmission between the slide rail 12 and the carriage 14 is disengaged under the action of the switching structure 15, so that the carriage 14 does not move synchronously with the slide rail 12, and the second object does not move. Along with the removal of the moving buffer distance of the sliding rail 12 which continues to move, the first connecting piece 13 can be pulled to move, and then the synchronous movement of the first object is pulled, so that the use requirements of different movements of the first object and the second object are reliably met through the movement transmission of the transmission mechanism 1.

Specifically, in some embodiments, the length of the movement buffer distance is set to be greater than or equal to the length of the distance that the carriage 14 and the sliding rail 12 can move synchronously, so that the sliding rail 12 can continue to move to pull the first connecting piece 13 after the switching structure 15 unlocks the carriage 14 and the sliding rail 12, and the function of unsynchronized movement of the first object and the second object is reliably achieved.

As shown in fig. 2 and 3, the slide rail 12 includes a slide rail body 121 and a first mounting hole 123. The slide rail body 121 includes a first side plate 1211 and a second side plate 1212 disposed opposite to each other, and a first through hole 122 is formed between the first side plate 1211 and the second side plate 1212. The first mounting hole 123 is formed in the first side plate 1211, and the first mounting hole 123 is communicated with the first through hole 122, the first connecting member 13 is disposed in the first through hole 122, and one end of the first connecting member 13 for connecting with a first object is penetrated out of the first mounting hole 123, and the second side plate 1212 is used for connecting with an external traction device. Specifically, in some embodiments, the length of the first through hole 122 is set to be greater than or equal to the length of the first connection member 13, so that the first connection member 13 can be smoothly installed into the first through hole 122 and can be penetrated out of the first installation hole 123 for connection of the first object.

As shown in fig. 2 and 3, in the embodiment of the present invention, the first connection member 13 is provided with a connection hole 131 at one end for connection with the first object, and the first object is connected by being connected with the connection hole 131. An abutment 132 for abutting against the first side plate 1211 is provided on the other end opposite to the end on which the connection hole 131 is provided on the first connection member 13. The abutting piece 132 abuts against the first side plate 1211, and thus the driving force of the slide rail 12 can be obtained, so that the first link 13 can move in synchronization with being pulled by the slide rail 12. In some embodiments, the abutting piece 132 may be an abutting plate provided on the other end opposite to the first connecting piece 13 where the connecting hole 131 is provided, and symmetrically provided on both sides opposite to the end. The abutting plate is arranged so that the cross-sectional area of the end of the first connecting piece 13 is larger than that of the first mounting hole 123, so that the first connecting piece 13 can be prevented from being directly detached from the mounting hole. Thus, by the limit of the abutment 132 and the abutment with the first side plate 1211, a reliable pulling of the first object movement is achieved.

As shown in fig. 2 and 3, the second side plate 1212 is provided with a connection structure 124, and the traction device is connected to the connection structure 124. The traction device is an external component and is used for providing driving force for pulling the sliding rail 12 to move. And the connecting structure 124 may be a member such as a connecting lug or a connecting column, which is convenient for connecting the traction device, so as to enable connection to be achieved smoothly. In some embodiments of the present invention, the connection structure 124 is configured as a connection slot, and the connection convenience is improved by clamping the component for connection on the traction device into the connection slot. In order to enhance the reliability of the connection between the traction device and the slide rail 12, a third side plate 1213 is disposed on the slide rail body 121, the third side plate 1213 is disposed at a distance from the second side plate 1212, and a fourth side plate 1214 is connected between the second side plate 1212 and the third side plate 1213. The connecting slot extends from the second side plate 1212, through the fourth side plate 1214, and onto the third side plate 1213. Specifically, in this arrangement, the connecting grooves formed on each side plate have an open end and a closed end, and the connecting grooves have a shape substantially as follows after extending on each side plate: the open end of the connecting slot is located on the edge of the second side plate 1212 and passes through the fourth side plate 1214, and then forms a closed end of the connecting slot in place inside the third side plate 1213. Thus, the means for connection on the traction device snaps in from the opening on the edge of the second side plate 1212 and then follows the trajectory of the connection slot through the fourth side plate 1214 into the connection slot on the third side plate 1213.

As shown in fig. 2 and 4, the carriage 14 includes a first frame body 141 and a second frame body 142. The first frame 141 is provided with a second mounting hole 140, and the sliding rail body 121 is penetrated in the second mounting hole 140. The second frame 142 is connected to the first frame 141 and is located between the slide rail body 121 and the bracket body 11. And the second object is connected with the first frame 141, and the switching structure 15 is arranged among the bracket body 11, the second frame 142 and the sliding rail 12. In this way, under the action of the switching structure 15, the second frame 142 receives the driving force generated when the sliding rail 12 moves, so as to drive the first frame 141 to move, and the second object is connected with the first frame 141, so that the function of driving the second object to move can be achieved. Specifically, the end of the second object, which is connected to the first frame 141, is inserted through the first through hole 122 on the sliding rail body 121, and then is movably connected or abutted to the first side plate 1211, so that the first frame 141 can synchronously follow the movement of the first frame 141 when the first frame 141 moves along the sliding rail body 121.

As shown in fig. 2 and 4, in the embodiment of the present invention, in order to equalize the stress of the first frame 141 and improve the motion stability of the first frame 141, two second frames 142 are provided, and two second frames 142 are respectively connected to opposite ends of the first frame 141, and a switching structure 15 is provided between each second frame 142 and the corresponding slide rail body 121 and the corresponding bracket body 11. Thus, the two ends of the first frame 141 are all driven by the driving force, so that the first frame 141 can move stably and smoothly, and the reliability of driving the second object to move is improved. In some embodiments, two switching structures 15 are provided between each second frame 142 and the frame body 11 and the slide rail body 121, so as to improve the accuracy of the overall movement and ensure that the control system can reliably operate.

As shown in fig. 2 to 4, the switching structure 15 includes a receiving groove 151, a second through hole 152, a ball 153, and an unlocking groove 154. The accommodating groove 151 is disposed on the sliding rail body 121 and faces the second frame 142; the second through hole 152 is formed in the second frame 142 and is communicated with the accommodating groove 151; a ball 153 is provided in the accommodation groove 151 and the second through hole 152, the ball 153 being used to lock and connect or unlock the carriage 14 with or from the slide rail 12; an unlocking groove 154 is provided at a side of the bracket body 11 facing the second bracket body 142, and the unlocking groove 154 is used for accommodating the balls 153 so as to unlock and separate the sliding bracket 14 from the sliding rail 12. In this arrangement, in the initial state, the balls 153 are located in the region formed in the accommodation groove 151 and the second through hole 152, and the depth of the accommodation groove 151 is smaller than the diameter size of the balls 153, so that at least a part of the balls 153 are located in the second through hole 152. Likewise, the depth of the second through hole 152 is also smaller than the diameter of the ball 153 so that at least a portion of the rolling motion is within the receiving groove 151. In the initial state, since the inner wall of the holder body 11 is covered on the second through hole 152, the balls 153 can be defined in the second through hole 152, and the position of the unlocking groove 154 provided on the inner wall of the holder body 11 is not greater than the length of the movement buffer distance from the position of the second through hole 152. In this way, when the sliding rail body 121 moves in a dislocation manner relative to the sliding frame 14, the balls 153 are clamped between the sliding rail body 121 and the sliding frame 14, so that the driving force can be transmitted through the balls 153, and the sliding frame 14 moves in the bracket body 11 along with the sliding rail body 121 synchronously, so as to drive the second object to move. When the carriage 14 moves to the unlocking groove 154, the inner wall of the bracket body 11 releases the limit on the position of the balls 153, and the balls 153 are forced to be separated from the accommodating groove 151, so that part of the balls 153 enter the unlocking groove 154. Since there is no ball 153 between the slide rail body 121 and the slide frame 14 to transmit the driving force, the slide frame 14 can no longer move synchronously with the slide rail body 121. At this time, the sliding rail body 121 that continues to move can pull the first connecting piece 13 to move, so as to further pull the first object to move. In the process of pulling the first connecting piece 13 by the sliding rail body 121, the sliding frame 14 can be limited without resetting because the ball 153 is clamped between the unlocking groove 154 and the second through hole 152. Only when the slide rail body 121 performs the return movement, the slide frame 14 performs the return movement when the balls 153 enter between the second through holes 152 and the receiving groove 151. By arranging the switching structure 15, the driving force switching between the first object and the second object is reliably realized, the design ingenious is good, and the actual use requirement is well met.

As shown in fig. 3 and 4, a guide groove 125 is formed on a surface of the slide rail body 121 facing the second frame body 142, a guide block 143 is correspondingly formed on the second frame body 142, and the guide block 143 is slidably disposed in the guide groove 125. In this way, the movement of the carriage 14 on the slide rail body 121 can be guided by the mating structure provided with the guide groove 125 and the guide block 143, and the stability of the movement of the carriage 14 on the slide rail body 121 is improved.

As shown in fig. 5, the transmission mechanism 1 (refer to fig. 1) further includes a second connecting member 16. The second connecting piece 16 is used for abutting a second object, and the second connecting piece 16 is connected to the first frame 141. Specifically, the second connector 16 is preferably a plate-shaped member, and may be connected to the first frame 141 by means of a snap fit or screw fixation. In the embodiment of the present invention, the second connecting piece 16 is provided with a buckle, and the second connecting piece 16 and the sliding frame 14 can be quickly connected by inserting the buckle into the second mounting hole 140 to be clamped and fixed. The provision of the second connector 16 increases the contact area with the carriage 14, and can uniformly transmit the force between the second object and the carriage 14.

In the transmission mechanism 1 provided in the embodiment of the invention, a switching structure 15 is arranged among the bracket body 11, the sliding frame 14 and the sliding rail 12, and a moving buffer distance is arranged between the first connecting piece 13 and the sliding rail 12. Therefore, the first object and the second object can move out of sync, the use requirement that the two objects can be driven to move out of sync through the same driving device is met, and the design ingenious is good.

The process of the transmission mechanism 1 for realizing traction of the movement of the first object and the second object is as follows: the first object is connected to the first connecting piece 13, the second object is connected to the carriage 14, and the traction device is connected to the slide rail 12. In this way, when the traction device pulls the sliding rail 12 to move, the sliding frame 14 and the sliding rail 12 are synchronously moved under the connection action of the switching structure 15, so that the second object connected with the sliding frame 14 can obtain driving force to move. Because the first connecting piece 13 and the sliding rail 12 have a moving buffer distance, before the sliding frame 14 and the sliding rail 12 synchronously move for a stroke of moving buffer distance, the sliding rail 12 does not drive the first connecting piece 13 to move, and therefore, a first object connected with the first connecting piece 13 is not driven to move. After the carriage 14 and the slide rail 12 move synchronously with respect to the bracket body 11 by a travel of a movement buffer distance, the movement transmission between the slide rail 12 and the carriage 14 is disengaged under the action of the switching structure 15, so that the carriage 14 does not move synchronously with the slide rail 12, and the second object does not move. Along with the removal of the moving buffer distance of the sliding rail 12 which continues to move, the first connecting piece 13 can be pulled to move, and then the synchronous movement of the first object is pulled, so that the use requirements of different movements of the first object and the second object are reliably met through the movement transmission of the transmission mechanism 1.

As shown in fig. 6, there is also provided a laundry treating apparatus, mainly of the pulsator washing machine type, in an embodiment of the present invention. By adopting the transmission mechanism 1, the clothes treatment device can realize the washing functions of multiple modes, so that the same clothes treatment device can meet different washing requirements. The laundry treating apparatus includes a base plate 20, a washing tub, a pulsator, a tub, a drain assembly 21, a clutch 22, a traction device 23, and the above-described driving mechanism 1. It will be understood, of course, that the laundry treating apparatus further includes other parts necessary for implementing the washing function, such as a driving device for driving the washing tub and the pulsator to rotate, other structures for mounting and fixing the above parts, and the like, which are not described herein.

Specifically, a receiving chamber for receiving laundry is formed inside the washing tub, and the pulsator is disposed inside the washing tub and at the bottom of the washing tub. The pulsator is used for stirring clothes in the accommodating cavity when rotating so as to wash the clothes in the accommodating cavity. The tub is used for containing washing water, the tub is arranged in the tub, the tub and the tub are preferably arranged in a cylindrical shape, and are coaxially arranged, and the pulsator is preferably arranged coaxially with the tub, so that stable rotation can be maintained in the rotation process. The tub is provided with a drain port, a drain assembly 21 (refer to fig. 6) is provided at the drain port, and opening or closing of the washing water draining action is controlled by the drain assembly 21. Specifically, a plurality of through holes are formed in the washing tub, the washing tub is arranged in the water holding tub, and the inner cavity of the water holding container is communicated with the accommodating cavity of the washing tub through the through holes, so that washing water in the water holding tub can enter the washing tub during washing, and the water draining assembly 21 opens the water draining hole during dewatering, and the washing water in the washing tub can flow into the water holding tub and then be drained through the water draining hole.

As shown in fig. 6, a clutch 22 is mounted on the base plate 20 and connected to the tub and the pulsator, and the clutch 22 can control the rotation modes of the tub and the pulsator by an internal transmission structure. If the clutch 22 controls the washing tub to be locked and not moved according to the current use requirement, only the pulsator can rotate, or the washing tub and the pulsator can synchronously rotate by control. In the embodiment of the present invention, the clutch 22 is provided for controlling at least the normal washing mode for locking the tub, the hand scrubbing mode for unlocking the tub, the spray washing mode for rotating the tub and the pulsator in synchronization, and the spinning mode. That is, by the control of the clutch 22, it is possible to lock the washing tub in the normal washing mode, and only the pulsator is rotated; or can realize the unlocking of the washing barrel in the hand scrubbing mode, but does not provide driving force for the washing barrel, and only drives the wave wheel to rotate in a movement mode; or can realize unlocking the washing barrel in the spray rinsing mode and provide driving force for the washing barrel so that the washing barrel and the pulsator can synchronously rotate; or can realize the unlocking of the washing barrel in the dehydration mode and provide driving force for the washing barrel, so that the washing barrel and the pulsator can synchronously rotate to carry out dehydration. In this way, the washing tub and pulsator can be rotated in different manners by different control methods performed by the clutch 22, so that different washing modes can be realized.

As shown in fig. 6, different control modes of the clutch 22 can be realized, different actions of the clutch 22 are required to be implemented, and the traction device 23 is used for providing driving force for driving the clutch 22 to act so as to be capable of switching between a normal washing mode, a hand scrubbing mode, a spraying washing mode and a dewatering mode according to the requirement. The driving force generated by the traction device 23 is transmitted to the clutch 22 through the transmission mechanism 1 described above. Specifically, the traction device 23 and the transmission mechanism 1 are both mounted on the base plate 20, and the clutch 22, the drainage assembly 21 and the traction device 23 are all connected with the transmission mechanism 1, and the transmission mechanism 1 is used for receiving the driving force generated by the traction device 23 to move a preset distance so as to be capable of transmitting the driving force to the clutch 22 or the drainage assembly 21. The traction device 23 has at least three movement ranges, and can provide one movement range or two movement ranges or three movement ranges according to actual control requirements, and the length range of one movement range is set according to actual use requirements. The acting force generated by the action of the traction device 23 is transmitted to the transmission mechanism 1, so that corresponding parts on the transmission mechanism 1 move, the clutch 22 can be driven to act, and the clutch 22 can execute corresponding control actions. And when the traction device 23 drives the drainage assembly 21 to move, the drainage function can be realized.

In the embodiment of the invention, through the clutch 22, the traction device 23, the drainage assembly 21 and the transmission mechanism 1, the washing barrel and the pulsator can rotate in different modes according to the needs under the cooperative movement among the parts, thereby meeting the requirements of different washing modes on the washing barrel and the pulsator in different washing modes and further realizing that the same clothes treatment device can have different types of washing modes. Meanwhile, the automatic water draining function according to the needs can be realized, and different washing demands of users are well met.

In the embodiment of the present invention, in different washing modes, the movement modes of the clutch 22, the traction device 23, the drainage assembly 21 and the transmission mechanism 1 are as follows:

when in the normal washing mode the clutch 22, the traction means 23 and the transmission 1 are all in an initial state in which the traction means 23 is not moving and the transmission 1 is not moving, the brake disc in the clutch 22 remains in a locked state locking the washing tub and the pulsator rotates for washing the laundry. In this mode, the drain assembly 21 is in a closed state.

When the traction device 23 starts to work in the hand scrubbing mode, the sliding rail 12 and the sliding frame 14 on the transmission mechanism 1 can be moved by one movement distance, and in the movement, the clutch 22 can be driven to act, so that a brake disc in the clutch 22 can not lock and lock the washing barrel any more; the washing barrel is in a free state, and the pulsator is in a rotating state, so that the pulsator can be driven to rotate in the opposite direction through the resistance of water flow and clothes after rotating, and the aim of rubbing and washing by hands is fulfilled. In this mode, the drain assembly 21 is in a closed state.

When in the spray washing mode, the traction device 23 works and moves two movement distances, the traction device 23 pulls the sliding rail 12 and the sliding frame 14 on the transmission mechanism 1 to also move two movement distances, in the movement, for the clutch 22, the brake disc in the clutch 22 does not lock the washing barrel, the washing barrel is still in a free state, the shifting fork in the clutch 22 is disengaged from the ratchet wheel, so that the washing barrel and the pulsator can synchronously rotate, the washing barrel and the pulsator can rotate in the same direction to play a role of lifting water flow upwards, so that the washing water can move upwards along the inner wall of the water containing barrel, and then spray downwards from the upper part of the washing barrel to achieve the purpose of spray washing. In this mode, the drain assembly 21 is in a closed state.

When in the dehydrating mode, the traction device 23 moves three movement distances, and during the movement, when the sliding frame 14 moves synchronously along the sliding rail 12 for two movement distances, the brake disc in the clutch 22 no longer locks the washing tub, the washing tub is in a free state, and the shifting fork in the clutch 22 is disengaged from the ratchet wheel, so that the washing tub and the pulsator can synchronously rotate. When the slide rail 12 continues to move to the third movement distance, the slide frame 14 on the transmission mechanism 1 is disconnected from the slide rail 12, and does not move synchronously with the slide rail 12. At this time, the moving slide rail 12 will abut against the first connecting piece 13, and pull the first connecting piece 13 to move synchronously, and the first connecting piece 13 can open the drain valve to realize the drainage function.

The different washing modes can be selected by a user according to the actual washing requirements. And the combination of different washing modes can be realized according to the actual conditions of washing clothes. If the high-grade or less dirty clothes are required to be washed, the washing can be performed by only rotating the pulsator according to the conventional washing mode of only rotating the pulsator positively and negatively, and meanwhile, the washing mode is combined with the spray rinsing mode to generate the impact water so as to quickly dissolve the washing powder and wet the clothes. When a small amount of common clothes or dirtier clothes are washed, a hand scrubbing mode can be selected to improve the washing efficiency, and the mutual friction of the washing barrel, the clothes and the pulsator is increased to improve the washing ratio. The clothes treatment device integrates a plurality of washing modes, thereby meeting different washing demands of users.

In some embodiments, the above-mentioned transmission mechanism 1 is applied to the laundry treating apparatus, and thus, the first object is the drain assembly 21, and the second object is the clutch 22.

As shown in fig. 7, in the embodiment of the present invention, the drain assembly 21 includes a drain valve 211 and a tension spring 212. A drain valve 211 is provided at the drain port for controlling the drain port to be opened or closed; the tension spring 212 is used for pulling the drain valve 211 to open, one end of the tension spring 212 is connected with the first connecting piece 13 (refer to fig. 1), and the second end of the tension spring 212 is connected with the drain valve 211. In this way, when the first connector 13 is pulled to follow the slide rail 12 for transportation, the water discharge valve 211 is opened by the transmission of the tension spring 212, and the tension spring 212 is elastically deformed at this time. When the transmission mechanism 1 is reset and conveyed, the tension spring 212 is elastically reset, so that the water discharge valve 211 can be closed, and the first connecting piece 13 can be pulled to be reset to the initial position.

As shown in fig. 8, in the embodiment of the present invention, the traction device 23 includes a traction rope 231 and a traction body 232. The traction rope 231 is used for pulling the slide rail 12 (refer to fig. 1) to move a preset distance, and the traction body 232 is used for providing a driving force for pulling the traction rope 231 to move. Specifically, the traction body 232 may be a member (e.g., a motor) capable of rotating the winding traction rope 231. One end of the traction rope 231 is connected with the sliding rail 12, the other end of the traction rope 231 is connected with the traction body 232, and when the traction body 232 rotates to wind up the traction rope 231, the function of pulling the sliding rail 12 to move can be achieved through the traction rope 231. The traction body 232 can perform at least three actions of winding the traction ropes 231 with different lengths according to control requirements, so that the movement distance of one stroke or the movement distance of two strokes or the movement distance of three strokes of the sliding rail 12 can be achieved. The rolling amount of the movement distance of one stroke is based on the displacement requirement of the slide rail 12 caused by actual requirement, so as to meet the actual use requirement.

As shown in fig. 6 and 9, the clutch 22 includes a control assembly 221 and a transmission assembly 222. The control component 221 is used for switching the working states of the washing barrel and the pulsator, and the washing barrel and the pulsator are connected with the control component 221; the transmission assembly 222 is used for transmitting the acting force on the slide rail 12 (refer to fig. 1) to the control assembly 221, the transmission assembly 222 is abutted with the slide frame 14, and the control assembly 221 is abutted with the transmission assembly 222. Specifically, the control component 221 is movably connected to the bottom plate 20 through a first connecting shaft, so that the control component can swing around the first connecting shaft as a rotation center after being stressed; the transmission assembly 222 is movably connected to the bottom plate 20 through a second connecting shaft, so that the transmission assembly can swing around the second connecting shaft as a rotation center after being stressed. Thus, when the traction device 23 pulls the slide rail 12 to move, the slide frame 14 moves along with the slide rail, so that the transmission assembly 222 can be driven to swing by taking the second connecting shaft as a rotation center, the control assembly 221 is abutted against the transmission assembly 222, and the swinging transmission assembly 222 generates driving force for the control assembly 221, so that the control assembly 221 moves, and further corresponding control can be performed to change the working states of the washing tub and the pulsator. After the traction device 23 no longer generates driving force, the traction device can automatically reset to an initial state under the action of the reset force of the control component 221 and the transmission component 222, and meanwhile, the traction device can push the sliding frame 14 and the sliding rail 12 to reset, so that the design ingenious is good.

As shown in fig. 6 and 9, in the embodiment of the present invention, the transmission assembly 222 includes a lever 2221 and a first elastic restoring member 2222. One end of the shift lever 2221 is abutted against the sliding frame 14, and a second connecting shaft is arranged at the other end of the shift lever 2221 in a penetrating way; the first elastic restoring element 2222 is mounted on the second connecting shaft and connected to the shift lever 2221, the first elastic restoring element 2222 is configured to provide a restoring driving force to the shift lever 2221, and the control assembly 221 abuts on the shift lever 2221. Specifically, one end of the lever 2221 abuts on the carriage 14, receiving the driving force generated when the carriage 14 is conveyed. And the shift lever 2221 can drive the brake disc in the clutch 22 to act in the process of swinging under the force, so as to unlock the motion of the washing barrel and enable the washing barrel to rotate. Meanwhile, the swinging shift lever 2221 can also elastically deform the first elastic restoring member 2222 so that the shift lever 2221, the carriage 14 and the slide rail 12 can be restored to the original state by the urging force generated by the first elastic restoring member 2222 after the urging force generated by the traction device 23 is canceled.

As shown in fig. 6 and 9, in the embodiment of the present invention, the control assembly 221 includes a ratchet 2211, a shift fork 2212, an adjustment lever 2213, a brake disc 2214, and a second elastic restoring member 2215. The washing tub and the pulsator are respectively connected with a ratchet wheel 2211, and a shift fork 2212 is used for being abutted with the ratchet wheel 2211 so as to control the working state of the corresponding ratchet wheel 2211. Specifically, when the tub or pulsator rotates while the shift fork 2212 is engaged with the ratchet 2211, the shift fork 2212 restricts the rotation of the ratchet 2211 so that the tub or pulsator does not rotate synchronously. When the shift fork 2212 is disengaged from the ratchet 2211, the shift fork 2212 does not rotate the ratchet 2211, so that the washing tub and the pulsator rotate synchronously. An adjustment lever 2213 is connected to the shift fork 2212, and the adjustment lever 2213 is configured to abut against the shift lever 2221 so as to be capable of driving the shift fork 2212 to swing. The adjustment lever 2213 is preferably a threaded rod, so that the distance between the adjustment lever 2213 and the shift lever 2221 can be adjusted as required, and the precision of motion coordination is improved. The brake disc 2214 is connected with the deflector rod 2221, and the brake disc 2214 is used for controlling the movement of the washing barrel; the second elastic restoring member 2215 is mounted on the first coupling shaft and coupled to the shift fork 2212, and the second elastic restoring member 2215 is used for providing restoring driving force to the shift fork 2212. Thus, when the traction device 23 pulls the sliding rail 12 to move a movement distance, the deflector rod 2221 is forced to swing, so that the brake disc 2214 moves and the washing tub is not locked. When the traction device 23 pulls the slide rail 12 to move by two movement distances, the swing range of the shift lever 2221 is larger, not only the brake disc 2214 is unlocked, but also the shift lever 2221 swings to push the adjusting rod 2213, the acting force is transmitted through the adjusting rod 2213, so that the shift fork 2212 swings around the first connecting shaft, and the shift fork 2212 can be disengaged from the ratchet 2211 along with the increase of the swing range of the shift fork 2212. Meanwhile, in the process of swinging the shift fork 2212, the second elastic restoring member 2215 is driven to elastically deform, so that after the acting force generated by the traction device 23 is removed, the shift fork 2212 can be restored to the initial state under the acting force generated when the second elastic restoring member 2215 is restored, and the shift fork 2212 is restored to the state of being matched with the ratchet 2211 after being restored.

Of the above, the first elastic restoring member 2222 and the second elastic restoring member 2215 are preferably provided as torsion springs. The movement relationship between the slide rail 12 and the various parts in the overall clutch 22 is substantially: when the slide rail 12 moves a movement distance, the brake disc 2214 is unlocked by swinging the shift lever 2221. In addition, the lever 2221 that swings at this time does not generate pushing force on the adjustment lever 2213, and only when the slide rail 12 moves by two movement distances, the lever 2221 is moved to push the adjustment lever 2213. After the slide rail 12 moves by two movement distances, the shift fork 2212 is driven to be disengaged from the ratchet 2211 under the transmission of the adjusting rod 2213. After the acting force of the traction device 23 is removed, the shift fork 2212 and the shift lever 2221 are reset under the action of the reset force generated by the first elastic reset element 2222 and the second elastic reset element 2215, so that the carriage 14 and the slide rail 12 can be pushed to be reset to the initial state.

The clothes treatment device provided by the embodiment of the invention has the advantages that the clothes treatment device simultaneously has a plurality of washing functions such as conventional washing, hand rubbing, spray rinsing, dehydration modes and the like through the motion coordination of the clutch 22, the traction device 23, the drainage assembly 21 and the transmission mechanism 1, and can be combined into a plurality of washing modes according to the rotation of the impeller and the rotation of the washing barrel, such as a conventional washing mode with the impeller rotating in the forward and reverse directions only, a hand rubbing mode with the impeller rotating in the reverse directions simultaneously with the washing barrel, or a spray washing mode with the impeller rotating simultaneously with the washing barrel to promote water flow to enhance the washing effect and the like. Therefore, a plurality of washing modes can be realized through one clothes treatment device, the opening and closing of the water draining function can be realized through the transmission mechanism 1, different washing demands of users can be met, and the washing is convenient.

The embodiment of the invention also provides a control method for controlling the upper clothes treatment device, which comprises the following steps:

acquiring a washing mode selected by a user; because the actual washing demands of users are different, if a small amount of common clothes or dirtier clothes need to be washed, a hand scrubbing mode can be selected to improve the washing efficiency; and when washing the high-grade or less dirty clothes, the conventional washing mode can be selected for washing. Therefore, before washing, the user can select a washing mode according to the laundry condition that the actual washing is required to wash.

When the user finishes selecting the washing mode, the user needs to judge whether the washing mode is a normal washing mode or a hand scrubbing mode or a spray washing mode and a dehydration mode according to the washing mode selected by the user, and after judging a certain washing mode, the user can execute corresponding washing action to perform corresponding washing treatment on the clothes.

If the normal washing mode is judged, the traction device 23 is not started, the transmission piece and the clutch 22 do not move, the washing barrel is locked, and the drain valve 211 is closed at the moment; specifically, when it is determined that the normal washing mode is executed, the traction device 23 does not act, and the slide rail 12 is not pulled to move, and the clutch 22 is in the initial state, and the brake disc 2214 locks the washing tub, and only the pulsator rotates to wash. In the normal washing, the drain valve 211 is closed, and no water is discharged.

If the hand scrubbing mode is judged, starting the traction device 23, and enabling the traction device 23 to pull the sliding rail 12 to move a preset distance to drive the clutch 22 to work so as to unlock the washing tub, wherein the drain valve 211 is closed; specifically, when it is determined that the hand scrubbing mode is performed, the traction device 23 is energized to pull the slide rail 12 to move by one movement distance. At this time, the lever 2221 drives the brake disc 2214 to move to unlock the washing tub, so that the washing tub is no longer locked and is in a free state. Therefore, when washing, the pulsator is in a rotating state, and after the pulsator rotates, the washing barrel can be driven to rotate in the opposite direction through the resistance of water flow and clothes. Thus, the pulsator and the washing barrel rotate in opposite directions to achieve a hand scrubbing mode. In the hand scrubbing mode, the drain valve 211 is still closed, and no drain is performed.

If the spray washing mode is judged, starting the traction device 23, and the traction device 23 pulls the slide rail 12 to move for two preset distances to drive the clutch 22 to work so as to unlock the washing barrel, and disengaging the shifting fork 2212 of the clutch 22 from the ratchet wheel 2211 to enable the washing barrel and the impeller to synchronously rotate, so that the drain valve 211 is closed; specifically, when it is determined that the shower washing mode is executed, the traction device 23 is energized to pull the slide rail 12 to move two movement distances. At this time, the lever 2221 drives the brake disc 2214 to move to unlock the washing tub, so that the washing tub is no longer locked and is in a free state. Meanwhile, the shift lever 2221 is abutted against the adjusting rod 2213 to push the shift fork 2212 to move, so that the shift fork 2212 is separated from the ratchet wheel 2211, the washing barrel and the pulsator can synchronously rotate, and then water flow sprays downwards from the upper part of the washing barrel to impact clothes, so that the aim of spraying and washing is fulfilled. In the shower mode, the drain valve 211 is still closed, and no water is discharged.

If the dehydrating mode is judged, starting the traction device 23, wherein the traction device 23 pulls the sliding rail 12 to move three preset distances to drive the first connecting piece 13 to pull the drainage assembly 21 to be opened; at this time, the clutch 22 keeps unlocking the washing tub, and at the same time, the shift fork 2212 of the clutch 22 is disengaged from the ratchet 2211, so that the washing tub and the pulsator rotate synchronously. Specifically, when it is determined that the dehydration mode is executed, the traction device 23 is energized to pull the slide rail 12 to move three movement distances. At this time, the lever 2221 drives the brake disc 2214 to move to unlock the washing tub, so that the washing tub is no longer locked and is in a free state. Meanwhile, the shift lever 2221 is abutted against the adjusting rod 2213 to push the shift fork 2212 to move, so that the shift fork 2212 is separated from the ratchet wheel 2211, and therefore the washing barrel and the pulsator can synchronously rotate, and the washing barrel and the pulsator can rotate at a high speed, and the aim of dehydrating clothes in the washing barrel is fulfilled. In the dehydration mode, the drain valve 211 is opened to enable drainage.

Specifically, in the dehydration mode, during the movement of the first two preset distances to the third preset distance of the slide rail 12, the slide frame 14 is disconnected from the slide rail 12, the slide frame 14 no longer moves along with the slide rail 12, and the slide rail 12 at this time pulls to abut against the first connecting piece 13, so that the first connecting piece 13 can be pulled to move, and the purpose of opening the drainage assembly 21 to drain water is achieved. The predetermined distance is a movement distance generated when the traction device 23 rotates.

The control method provided by the embodiment of the invention controls the clothes washing device to have high reliability of executing corresponding washing actions, and when the control method is used, a user can select different washing modes according to the type material and the dirt degree of clothes, so that the washing requirement of the corresponding clothes is reliably met.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
