Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and more specifically, relates to a clothing processing device. Background Art

[0002] When the clothing processing equipment is installed, the drain valve is generally opened by introducing a traction rope into the drain valve, and during the traction process, the clutch lever is simultaneously driven to move to change the state of the clutch. Due to the relationship between the drain valve, the traction device and the clutch, the setting of the relevant drain valve is affected by the traction rope and the clutch lever. For example, the heights of the traction rope and the clutch lever are relatively high, resulting in a higher height of the drain valve. The higher the height of the drain valve, the higher the height of the entire washing machine will be during installation. However, more and more countries hope to lower the height of the washing machine to facilitate the removal of clothes, so the relevant washing machines cannot meet the market's demand for reducing the overall height of the washing machine.

[0027] The embodiment of the present invention provides a clothing processing device. The clothing processing device may include a pulsator washing machine with an upper opening and a drum washing machine with a front opening according to the opening setting position and the washing method; the pulsator at the bottom of the washing tub of the pulsator washing machine rotates forward and backward, driving the clothes to flip up and down and left and right continuously, so that the clothes and the clothes and the tub wall are rubbed to remove dirt and wash; the clothes of the drum washing machine rotate through the drum, and the clothes are constantly lifted and dropped in the drum to perform repeated movements, and the clothes are removed and washed by being thrown. The embodiment of the present invention takes the clothing processing device as a pulsator washing machine with an upper opening as an example for explanation, and the washing machine includes a single washing washing machine with a separate washing function, a washing machine with a washing and dehydration function, and a washing and drying machine with a washing and drying function. Those skilled in the art can understand that the clothing processing device of the embodiment of the present invention may also be a spin dryer that performs dehydration alone without a washing function.

[0028] The drainage method of clothing processing equipment, such as washing machines, is generally that the traction cord is connected to one end of the drain valve rod, the drain valve rod is connected to the valve plug in the drain valve sealing chamber, and the valve plug can be moved to open and close the drain valve sealing chamber; when the washing machine is dehydrating, the traction device is activated, the traction cord is retracted inward to pull the drain valve rod, the drain valve rod pulls open the valve plug in the drain valve sealing chamber, and at the same time pulls open the clutch lever, so that the water inside the washing machine can be discharged through the drain valve sealing chamber, and the clutch is also switched to the dehydration mode, and the dehydration preparation is done. The traction cord of the relevant washing machine, the axis of the drain valve rod (the connecting line of the two ends of the drain valve rod connected to the traction cord and the drain valve sealing chamber respectively), the connection position of the clutch lever and the drain valve rod, and the axis of the drain valve sealing chamber are on the same horizontal line, and the distribution of the forces of each part is in the axial direction, so as to facilitate the balance of the drainage action. However, when the clothing processing equipment is installed, the height of the drain valve is subject to the height of the traction cord and the clutch lever.

[0029] like Figure 1-Figure 3 As shown, an embodiment of the present invention provides a clothes processing device, for example, the clothes processing device can be a pulsator washing machine, etc. The clothes processing device includes a drain valve assembly 1 and a tractor 2. Of course, it can be understood that the clothes processing device also includes other parts necessary for realizing the washing function, such as a driving device for driving the washing tub and the pulsator to rotate, and other structures for installing and fixing the above parts, etc., which are not described in detail here.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, the drain valve assembly 1 has a sealed cavity 11 inside, and the sealed cavity 11 extends along a first direction. For example, the sealed cavity 11 is a tubular structure, and the cross section is roughly circular. The axis of the symmetry axis of the sealed cavity 11 is an axis passing through the center of the cross section and perpendicular to the cross section; the first direction is the extension direction of the axis of the symmetry axis, which is also as shown in FIG. Figure 1 L1 direction as shown. A valve plug is provided in the sealed cavity 11 and can move along the first direction to open and close the sealed cavity 11. The valve plug has good sealing performance, for example, a rubber part. It can be understood that when the valve plug closes the sealed cavity 11, the sealed cavity 11 remains closed, and the water flow in the clothes processing device cannot enter the sealed cavity 11; when the valve plug opens the sealed cavity 11, the sealed cavity 11 remains open, and the water flow in the clothes processing device can enter the sealed cavity 11 and flow out to the outside through a pipe structure such as a drain pipe.

[0031] like Figure 1 , Figure 4 and Figure 5As shown, the overall principle of the tractor 2 is to convert the energy provided by a driving device such as an electric motor into the power required for work through a transmission mechanism to achieve the normal operation of the clothing processing device. The tractor 2 has a pull cord 21 connected to the drain valve assembly 1, and the pull cord 21 is connected to the valve plug to drive the valve plug to move in the sealed cavity 11 along a first direction to open and close the sealed cavity 11; when the tractor 2 is in motion, the pull cord 21 of the tractor 2 contracts inwardly, and the function of pulling the valve plug to move can be achieved through the pull cord 21, so that the valve plug in the sealed cavity 11 can be pulled open to open the sealed cavity 11. An elastic member, such as a tension spring hook, can be arranged between the pull cord 21 and the valve plug, and the pull cord 21 contracts inwardly to pull the tension spring hook, thereby pulling the valve plug in the sealed cavity 11 open to open the sealed cavity 11; when the pull cord 21 has no tension, the elastic member rebounds and drives the valve plug to return to the initial state to close the sealed cavity 11.

[0032] Since the pull rope 21 is usually a flexible component, the connection between the pull rope 21 and the drain valve assembly 1 can be achieved by, for example, directly binding the pull rope 21 to the drain valve assembly 1 or fixing it to the drain valve assembly 1 via screw-like connectors, or by providing connecting ears or connecting columns and other structures on the drain valve assembly 1 for the pull rope 21 to connect. All of the above methods can achieve the connection between the pull rope 21 and the drain valve assembly 1.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the pull rope 21 extends along the second direction. Figure 1 L2 direction shown; then, when the pull rope 21 pulls the drain valve assembly 1 along the second direction, the valve plug moves along the first direction to open and close the sealing cavity 11. Since there is a height difference between the first direction and the second direction, the drain valve assembly 1 is easily affected by the upper and lower unbalanced forces, causing itself to tilt.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, the first direction and the second direction are parallel, so the pulling force of the pull rope pulling the drain valve assembly is parallel to the pulling force on the valve plug, and the force transmission direction is not changed. The force loss is only the loss of torque caused by the height difference between the first direction and the second direction. Therefore, the force loss is small, and the pulling force of the pull rope pulling the drain valve assembly can be more used to pull the valve plug. The lost force is converted into an unbalanced force on the drain valve assembly, so the degree of inclination of the drain valve assembly can also be reduced.

[0035] The sealing cavity of the embodiment of the present invention extends along the first direction, and the pull rope extends along the second direction. There is a height difference between the first direction and the second direction. Then, the pull rope applies a pulling force to the valve plug of the drain valve assembly along the second direction. The sealing cavity of the drain valve extends along the first direction, that is, the valve plug has space for its movement in the first direction. Since the first direction is parallel to the second direction, the pulling force of the pull rope along the second direction acts on the valve plug, which can drive the valve plug to move along the first direction, thereby opening the sealing cavity. The sealed cavity of the embodiment of the present invention extends along the first direction. When the first direction is lower than the second direction in height, the height of the drain valve assembly can be lowered, so that the height of the drain valve assembly is no longer restricted by the height of the pull rope of the traction device, so that it can match traction devices of different heights and adapt to multiple models of traction devices, thereby improving the compatibility of the drain valve assembly and the traction device installation; the drain port of the clothing processing equipment is connected to the drain valve assembly, so during installation, the height of the entire clothing processing equipment can also be reduced accordingly as the height of the drain valve assembly is reduced, thereby meeting the market demand for reducing the overall height of the clothing processing equipment, making it convenient for users to take clothes, and at the same time, the reduced height of the clothing processing equipment can also reduce logistics and transportation costs and increase the amount of cabinets loaded during logistics and transportation.

[0036] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the drain valve assembly 1 includes a body 12 and a pull rod 13. The body 12 has a sealed cavity 11 inside; the pull rod 13 is connected between the pull rope 21 of the tractor 2 and the valve plug to drive the valve plug to move. For example, the pull rod 13 and the valve plug can be connected by an elastic member such as a tension spring hook, and connected to the valve plug along the axis of the symmetry axis of the valve plug. The pull rope 21 contracts inward to pull the pull rod 13, and the pull rod 13 pulls the valve plug in the sealed cavity 11 through the tension spring hook to open the sealed cavity 11. Among them, the connection position between the pull rod 13 and the pull rope 21 is higher than the center position of the sealing chamber 11, that is, the connection position between the pull rod 13 and the valve plug, and the connection position between the pull rod 13 and the valve plug is located in the extension direction of the axis of symmetry of the sealing chamber 11. Then, when installing the drain valve assembly 1, the installation height of the drain valve assembly 1 can be lowered, so that the axis of symmetry of the sealing chamber 11 extends along the first direction, and the axis of symmetry of the sealing chamber 11 is lower than the connection position between the pull rod 13 and the pull rope 21, so that the height of the drain valve assembly 1 is no longer restricted by the height of the pull rope 21 of the traction device 2, and when the drain valve assembly 1 is connected to other structures of the clothing processing equipment, the other structures can be lowered accordingly as the installation height of the drain valve assembly 1 is reduced.

[0037] like Figure 1 , Figure 4 and Figure 5As shown, the connection position between the pull rod 13 and the pull rope 21 is located in the second direction, so the pulling force of the pull rope 21 pulling the pull rod 13 is along the second direction; the pull rod 13 is connected to the valve plug along the axis of symmetry of the valve plug, so the pulling force of the pull rod 13 pulling the valve plug is along the first direction, then, because the axis of symmetry of the pull rope 21 and the sealing chamber 11 are not at the same height, the pull rod 13 will be affected by the up and down unbalanced force, causing the pull rod 13 to tilt up and down.

[0038] The drain valve assembly of the embodiment of the present invention includes a body and a pull rod, and the connection position of the pull rod and the pull rope is higher than the extension position in the first direction. Then, by setting the pull rod, and the two ends of the pull rod are respectively connected to the pull rope and the valve plug at different heights, the height of the drain valve assembly can be reduced, so that the height of the drain valve assembly is no longer restricted by the height of the pull rope of the traction device, and during installation, the height of the whole machine of the clothing processing device can also be reduced accordingly with the reduction of the height of the drain valve assembly, thereby meeting the market's requirements for reducing the overall height of the clothing processing device. The embodiment of the present invention is conducive to reducing the overall height of the clothing processing device.

[0039] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the drain valve assembly 1 also includes a valve cover 14, which is connected between the body 12 and the pull rod 13 in the first direction, and there is no relative movement between the valve cover 14 and the body 12; wherein, the valve cover 14 and the pull rod 13 are both provided with a slidably connected guide member 3, so that the pull rod 13 slides in the first direction and the second direction, and the extension direction of the guide member 3 is parallel to the first direction and the second direction. It can be understood that the pull rod 13 is pulled by the pull rope 21 and moves in the second direction, and at the same time, the pull rod 13 pulls the valve plug to move in the first direction. Even if there is a height difference between the first direction and the second direction, so that the pull rod 13 is easily affected by the unbalanced force up and down and tilts, but under the guiding action of the guide member 3, the pull rod 13 can only be limited to relative sliding with the valve cover 14 in the extension direction of the guide member 3, so that the pull rod 13 will not tilt.

[0040] The drain valve assembly of the embodiment of the present invention further includes a valve cover, and the valve cover and the pull rod are both provided with a slidably connected guide member, so that the pull rod slides in the first direction and the second direction. The sliding connection makes it difficult for the valve cover and the pull rod to have an up-and-down displacement, but only a forward-and-backward displacement in the extension direction of the guide member, so that when the pull rod is subjected to a pulling force, the pull rod can slide smoothly in the first direction and the second direction under the guiding action of the guide member. Under the guiding action of the guide member, the drain valve assembly can maintain its own balance in the first direction and the second direction, and prevent itself from tilting under the action of the up-and-down unbalanced force. The embodiment of the present invention is conducive to the balance of the drainage action.

[0041] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the guide members 3 are respectively arranged at positions near the lower ends of the tie rod 13 and the valve cover 14. For example, if the distance between the guide member 3 and the lower ends of the tie rod 13 and the valve cover 14 is less than 1 / 2 of the distance between the guide member 3 and the upper ends of the tie rod 13 and the valve cover 14, then the distance between the guide member 3 and the lower ends of the tie rod 13 and the valve cover 14 is less than 1 / 3 of the overall distance between the upper and lower ends of the tie rod 13 and the valve cover 14. The guide members of the embodiment of the present invention are respectively arranged at positions near the lower ends of the tie rod and the valve cover, the connection position between the valve plug and the tie rod is located at the center position of the tie rod, and the connection position between the pull rope and the tie rod is located above the center position of the tie rod, so that the arrangement of the guide member is not likely to affect the connection between the valve plug and the tie rod, nor is it likely to affect the connection between the pull rope and the tie rod.

[0042] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the guide member 3 is a guide rail 31 protruding from the surface of the pull rod 13 and a groove 32 provided on the valve cover 14; or, the guide member 3 is a groove 32 provided on the pull rod 13 and a guide rail 31 protruding from the surface of the valve cover 14. In the embodiment of the present invention, the guide member is configured as a guide rail and a groove structure, which not only enables the pull rod to slide smoothly under the guidance of the guide member, but also has a simple structure, is easy to manufacture, and has good guiding stability.

[0043] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the valve cover 14 includes a cover-like portion 141 and a protrusion 142. The cover-like portion 141 is connected to the end of the body 12 in the first direction to cover the sealing cavity 11, wherein the cover-like portion 141 is provided with a first through hole 143 to communicate with the sealing cavity 11, and the axis of the first through hole 143 extends along the first direction. For example, the pull rod 13 can extend from the first through hole 143 into the sealing cavity 11 through an elastic member such as a tension spring hook to connect with the valve plug in the sealing cavity 11; the protrusion 142 is connected to the cover-like portion 141 and protrudes toward the tractor 2 in the first direction, and the protrusion 142 is arranged around the first through hole 143; wherein the protrusion 142 is provided with a guide member 3 to be slidably connected with the pull rod 13, and the protrusion 142 is located below the pull rod 13 to support the pull rod 13.

[0044] The valve cover of the embodiment of the present invention includes a cover-like portion and a protrusion. Since the pull rod is prone to collide with the main body when moving back and forth in the first direction, the cover-like portion is connected to the end of the main body in the first direction to cover the sealing cavity, which can provide certain protection for the main body and avoid direct collision between the pull rod and the main body; the protrusion is connected to the cover-like portion and protrudes toward the traction device along the first direction, thereby facilitating the setting of a guide member on the protrusion, so that the pull rod can be installed on the protrusion and slidably connected to the protrusion, and the structural setting is ingenious.

[0045] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the protrusion 142 partially overlaps with the cover 141 in the circumferential direction; the protrusion 142 is located at the lower side of the tie rod 13 and partially surrounds the tie rod 13 in the circumferential direction, and the tie rod 13 extends from one radial end of the cover to the other end. The embodiment of the present invention further defines the shape of the valve cover, so that the structure of the cover, the tie rod and the protrusion after installation is more compact.

[0046] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the clothing treatment device also includes a clutch assembly 4. The working principle of the clutch assembly 4 can be understood as follows: the clutch is a key component of the pulsator-type fully automatic washing machine. Its main function is to transmit the power of the motor to the clutch through the V-belt transmission after the motor is started, so that the clutch can realize low-speed rotation during washing and rinsing and high-speed rotation during dehydration, and perform the braking action at the end of dehydration. The action of the deceleration clutch is controlled by the drainage electromagnet, and there are two states: washing and dehydration. When washing, the motor runs, and the speed is reduced through the deceleration clutch to drive the pulsator to intermittently rotate forward and reverse for washing. At this time, the washing and dehydration barrel does not rotate; when dehydrating, the motor runs, and the washing and dehydration barrel is driven to run without deceleration (i.e., high speed) through the clutch to dehydrate. At this time, the pulsator also runs with the washing and dehydration barrel.

[0047] At present, the pulsator fully automatic washing machine usually uses a deceleration clutch, and the structure of the deceleration clutch is mainly composed of a pulsator shaft, a dehydration shaft, elastic parts such as torsion springs, a brake disc, a shift fork, a clutch lever, a ratchet, a pawl, a clutch sleeve, an outer sleeve shaft, and a gear shaft. Ratchets are respectively connected to the washing tub and the pulsator, and the shift fork is used to abut against the ratchet to control the working state of the corresponding ratchet. Specifically, when the washing tub or the pulsator rotates and the shift fork is in a matching state with the ratchet, the shift fork limits the rotation of the ratchet so that the washing tub or the pulsator does not rotate synchronously. When the shift fork is in a disengaged state with the ratchet, the shift fork does not limit the rotation of the ratchet, so that the washing tub and the pulsator rotate synchronously. The shift fork abuts against the clutch lever 42 to drive the shift fork to swing. The brake disc is connected to the clutch lever 42, and the brake disc is used to control the movement of the washing tub; the elastic member 43 abuts against the clutch lever 42, so that the clutch lever 42 and the shift fork can be elastically reset. In this way, when the tractor 2 pulls the rod 13 to move, the clutch lever 42 is forced to swing, causing the brake disc to move and release the locked washing tub. Moreover, the swing of the clutch lever 42 will push the fork to swing. As the swing range of the fork increases, the fork can be disengaged from the ratchet, and the fork no longer restricts the rotation of the ratchet, so that the washing tub and the pulsator rotate synchronously. At the same time, during the swing of the fork and the clutch lever 42, the elastic member 43 will be driven to undergo elastic deformation, so that after the force generated by the tractor 2 is canceled, the fork and the clutch lever 42 can be reset to the initial state under the force generated when the elastic member 43 resets itself. After the fork is reset, it returns to the state of mutual cooperation with the ratchet.

[0048] like Figure 1 , Figure 4 and Figure 5 As shown, when the tractor 2 is in motion, the pull rope 21 contracts inward and pulls the pull rod 13, and the clutch assembly 4 moves with the pull rod 13 to switch the working mode of the clothing processing device, which includes a washing mode and a dehydration mode. In the washing mode, the driving device such as the motor runs and drives the clutch assembly 4 to rotate through the transmission belt, the tractor 2 does not move, the pull rope 21 is in a relaxed state, so that the brake disc and the clutch assembly 4 do not move, the pawl is always in the ratchet inserted state, and the impeller shaft of the clutch assembly 4 drives the impeller to rotate to achieve the washing function; for the drain valve assembly 1, if the tractor 2 is not started, the sealed chamber 11 is in a closed state and no drainage is performed. In the dehydration mode, due to the tension of the pull rope 21 of the tractor 2, the brake disc and the clutch lever are driven to move, so that the pawl and the ratchet are disengaged. The impeller shaft and the dehydration barrel of the clutch assembly 4 are in a working state at the same time to achieve the dehydration function; for the drain valve assembly 1, the tractor 2 is started, and the sealed chamber 11 is in an open state, so that drainage can be performed.

[0049] The clothes processing device of the embodiment of the present invention also includes a clutch assembly, which switches the working mode of the clothes processing device with the movement of the pull rod. In the washing mode, the tractor does not move, and the pull rope is in a relaxed state. At this time, the clutch assembly only drives the impeller to rotate to achieve the washing function; and the sealed chamber is in a closed state, and no water is discharged. In the dehydration mode, the pull rope of the tractor is tensioned, and the clutch assembly can drive the impeller and the dehydration barrel to rotate at high speed at the same time to achieve the dehydration function; and the sealed chamber is in an open state under the pull of the pull rod, so that water can be discharged. The opening and closing of the sealed chamber and the working mode of the clothes processing device are synchronously controlled by the pull rope, thereby ensuring the storage of water flow during washing and the smooth discharge of water flow during dehydration.

[0050] like Figure 1 , Figure 4 and Figure 5 As shown, the clutch assembly 4 includes a clutch body 41, a clutch lever 42 and an elastic member 43. The clutch body 41 is used to switch the working mode, for example, it can be switched to a washing mode or a dehydration mode. The clutch lever 42 is connected between the pull rod 13 and the clutch body 41, so that the pull rod 13 drives the clutch body 41 to move to switch the working mode. When the tractor 2 is in motion, the pull rope 21 is tightened and drives the pull rod 13 to move. The movement of the pull rod 13 also drives the clutch lever 42 to rotate. In the process of the clutch lever 42 swinging under the force, it can drive the brake disc in the clutch body 41 to move, release the movement lock of the washing tub, and enable the washing tub to rotate. At the same time, the swinging clutch lever 42 presses against the elastic member 43, so that the elastic member 43 can also be elastically deformed, so that after the force generated by the tractor 2 is cancelled, the clutch lever 42 and the pull rod 13 can be reset to the initial state by the force generated by the elastic member 43.

[0051] The clutch assembly of the embodiment of the present invention includes a clutch body, a clutch lever and an elastic member. The clutch lever can swing under the tension of the pull rope of the tractor, thereby driving the clutch body to move, and then can perform corresponding control to change the working state of the washing tub and the pulsator. After the tractor no longer generates driving force, the clutch lever can automatically reset to the initial state under the reset force of the elastic member, and can also push the pull rod to reset, ensuring that the opening and closing of the drain valve can change with the working mode of the clothes processing device; and after resetting, it can meet the next control demand, and the design is ingenious.

[0052] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the clutch assembly 4 is located on one side of the pull rod 13, and a second through hole 131 is formed on the side of the pull rod 13. The extension direction of the second through hole 131 is perpendicular to the first direction. Figure 2The L3 direction shown, the L3 direction is as follows Figure 2 As shown, the clutch lever 42 extends from the side of the pull rod 13 into the second through hole 131 and abuts against the inner wall surface of the pull rod 13. In the first direction, the inner wall surface is located at the end of the second through hole 131 closest to the body 12, that is, as shown in FIG. Figure 1 The right end face of the second through hole 131 shown; when the traction device 2 is in action, the pull rope 21 pulls the pull rod 13 to move along the second direction, and the pull rod 13 moves from the main body 12 toward the traction device 2. Since the clutch lever 42 is in contact with the end of the pull rod 13 closest to the main body 12 in the second through hole 131, when the pull rod 13 just starts to move, it can simultaneously drive the clutch lever 42 to swing, so that when the sealing chamber 11 is opened and closed by the pull rod 13, the working mode of the clothing processing device can change along with the swing of the clutch lever 42.

[0053] like Figure 1 , Figure 4 and Figure 5 As shown, the extension direction of the clutch lever 42 and the second direction are located in the same plane, that is, the extension direction of the clutch lever 42 and the second direction have no height difference. Then, when the pull rope 21 pulls the pull rod 13 along the second direction, the clutch lever 42 contacts the pull rod 13 and moves along the second direction together with the pull rod 13, and there is no loss of force on the clutch lever 42 due to the height difference, so that the force loss is small, and the pulling force of the pull rope 21 can be used more to pull the clutch lever 42.

[0054] The clutch lever of the embodiment of the present invention extends into the second through hole and abuts against the inner wall surface of the pull rod, and the inner wall surface is located at the end of the second through hole closest to the main body in the first direction. Therefore, when the traction device is actuated, the consistency of the movement of the drain valve assembly and the clutch assembly pulled by the pull rope can be more accurately ensured, ensuring that the opening and closing of the drain valve can change with the working mode of the clothing processing equipment, thereby ensuring the storage of water during washing and the smooth discharge of water during dehydration.

[0055] In some embodiments, Figure 1 , Figure 4 and Figure 5As shown, the clothing treatment device further includes a washing tub, a pulsator and a water tub. A receiving cavity for receiving clothing is formed inside the washing tub. For a pulsator washing machine, the upper part of the receiving cavity is open, and the user can put clothing from the upper part of the receiving cavity; the pulsator is arranged in the washing tub and is located at the bottom of the washing tub. The pulsator can rotate forward and reverse relative to the washing tub to stir the clothing in the receiving cavity, so as to wash the clothing in the receiving cavity. The water tub is used to hold washing water, and the washing tub is arranged in the water tub. For example, the shape of the washing tub and the water tub can be set to be basically "cylindrical", and the two can be arranged coaxially, and the pulsator is also preferably arranged coaxially with the washing tub, so that it can maintain stable rotation during the rotation process. A drain outlet is arranged below the water tub, and the drain valve assembly 1 is arranged at the drain outlet. The body 12 of the drain valve assembly 1 is located below the drain outlet and communicated with the drain outlet. The valve plug is controlled to control the opening or closing of the sealing cavity 11 in the body 12 and the drain outlet. Because the drain valve assembly is located below the barrel, the height of the drain valve assembly can be set lower when the height of the drain valve assembly is independent of the height of the tractor, thereby lowering the overall height of the clothing processing device.

[0056] Specifically, a plurality of through holes are provided on the washing tub, and the washing tub is arranged in the water tub, and the inner cavity of the water tub is connected with the accommodating cavity of the washing tub through the through holes, so that during washing, the washing water contained in the water tub can flow into the washing tub, and during dehydration, the sealing cavity 11 is opened to communicate with the drain port, and the washing water in the washing tub can flow out of the water tub and then be discharged from the clothing processing device.

[0057] like Figure 1 , Figure 4 and Figure 5 As shown, the clutch assembly 4 is connected to the washing tub and the impeller, and the clutch assembly 4 can realize corresponding control of the rotation mode of the washing tub and the impeller through the internal transmission structure. For example, the clutch assembly 4 controls the washing tub to lock according to the current use requirements, and only allows the impeller to rotate, or controls the washing tub and the impeller to rotate synchronously. The clutch body 41 moves to switch the connection between the rotating shaft of the washing tub and the rotating shaft of the impeller to switch the working mode. In the washing mode, the rotating shaft of the washing tub and the rotating shaft of the impeller are not connected, the clutch body 41 only drives the impeller to rotate, and the washing tub does not rotate, and the drain valve remains closed at this time; in the dehydration mode, the rotating shaft of the washing tub and the rotating shaft of the impeller are connected, and the clutch body 41 provides a driving force so that the washing tub and the impeller can rotate synchronously for dehydration. In this way, through the different control methods performed by the clutch assembly 4, the washing tub and the impeller can be rotated in different ways, so that different washing modes can be achieved.

[0058] The clothes processing device of the embodiment of the present invention has multiple modes such as washing mode and dehydration mode through the movement coordination of the clutch assembly, the traction device and the drain valve assembly, and can be combined into multiple washing modes according to the rotation of the impeller and the rotation of the washing tub, such as a washing mode in which only the impeller rotates forward and reverse alternately, or a dehydration mode in which the impeller and the washing tub rotate simultaneously to increase the water flow, etc. Thus, multiple washing modes can be realized through one clothes processing device, which can meet the different washing needs of users and is convenient for washing.

[0059] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the body 12 of the drain valve assembly 1 is also provided with a water inlet 15 and a water outlet 16 connected to the sealed cavity 11. The water inlet 15 is connected to the drain port by a pipeline, and the water outlet 16 is connected to the outside by a pipeline. The extending direction of the water inlet 15 is perpendicular to the first direction, and the extending direction of the water outlet 16 is along the first direction. The extending direction of the water inlet 15 is as shown in FIG. Figure 1 The L4 direction shown is roughly the vertical direction of the clothes processing device when it is normally placed. When the clothes processing device is normally placed, the barrels such as the washing tub and the water tub are placed vertically, and the opening of the accommodating cavity is located at the top; the water flow direction is as shown in FIG. Figure 1 Direction of arrow shown.

[0060] The extension direction of the water inlet of the embodiment of the present invention is perpendicular to the first direction. Since the barrel body is located above the drain outlet, the washing water in the washing barrel can flow out of the water storage tub and flow directly into the sealed cavity below through the drain outlet and the water inlet along the downward flow of the water; the extension direction of the water outlet is along the first direction. When the water flows into the sealed cavity, the water flow changes its flow direction from flowing perpendicular to the first direction to flowing along the first direction, so that the water flow can be buffered here before flowing out to avoid the water flow flowing out to the outside at a high speed, causing the water flow to splash everywhere, which is not conducive to the user experience.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
