The embodiment of the utility model provides a clothes treatment device. The laundry treating apparatus may include an pulsator washing machine having an upper opening and a drum washing machine having a front opening according to an opening setting position and a washing manner; the pulsator at the bottom of the washing tub of the pulsator washing machine rotates positively and negatively to drive clothes to turn up and down and left and right continuously, so that friction is carried out between the clothes and the tub wall to clean the clothes; the clothes of the drum washing machine rotate through the drum, are continuously lifted and fall down in the drum to do repeated motion, and are decontaminated and cleaned through beating. The embodiment of the utility model is described by taking a pulsator washing machine with an upper opening as an example of clothes treatment equipment, wherein the washing machine comprises a single-washing machine with a single washing function, a washing machine with washing and dewatering functions and a washing and drying integrated machine with washing and drying functions. It will be appreciated by those skilled in the art that the laundry treating apparatus of the embodiment of the present utility model may be a dryer which performs dehydration alone without a washing function.

The drainage mode of clothes treatment equipment, such as washing machines, is generally that a traction device stay cord is connected with one end of a drainage valve pull rod, the drainage valve pull rod is connected with a valve plug in a drainage valve sealing cavity, and the valve plug can be moved to open and close the drainage valve sealing cavity; when the washing machine is used for dewatering, the tractor acts, the tractor pull rope is contracted inwards to pull the drain valve pull rod, the drain valve pull rod pulls the valve plug in the drain valve sealing cavity open, and meanwhile, the clutch pull rod pulls the clutch pull rod open, so that water in the washing machine can be discharged through the drain valve sealing cavity, and the clutch is also switched into a dewatering mode to be ready for dewatering. The axes of the traction device pull rope and the drainage valve pull rod (the connection lines of the two ends of the drainage valve pull rod connected with the traction device pull rope and the drainage valve sealing cavity respectively), the connection positions of the clutch deflector rod and the drainage valve pull rod and the axis of the drainage valve sealing cavity are positioned on the same horizontal line, and the stress distribution of each part is in the axial direction so as to be beneficial to the balance of drainage actions. However, the height of the drain valve is limited by the height of the retractor cords and clutch levers when the laundry treating apparatus is installed.

As shown in fig. 1 to 3, an embodiment of the present utility model provides a laundry treating apparatus, for example, the laundry treating apparatus may be a pulsator washing machine or the like. The laundry treating apparatus includes a drain valve assembly 1 and a tractor 2. It will be understood, of course, that the laundry machine further includes other parts necessary for performing a 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.

As shown in fig. 1, 4 and 5, the drain valve assembly 1 has a seal chamber 11 inside, the seal chamber 11 extends along a first direction, for example, the seal chamber 11 has a tubular structure, a cross section is approximately circular, and an axis of symmetry of the seal chamber 11 is an axis passing through a center of the cross section and perpendicular to the cross section; the first direction is the extending direction of the symmetry axis, and is also the L1 direction as shown in fig. 1. The sealing cavity 11 is internally provided with a valve plug which can move along a first direction to open and close the sealing cavity 11, and the valve plug has better sealing performance, such as a rubber piece. It will be appreciated that when the valve plug closes the seal chamber 11, the seal chamber 11 remains closed and water flow within the laundry treatment apparatus cannot enter the seal chamber 11; when the valve plug opens the sealing chamber 11, the sealing chamber 11 is kept open, and water flow in the laundry treating apparatus can enter the sealing chamber 11 and flow out to the outside through a pipe structure such as a drain pipe.

An elastic piece, such as a tension spring hook, can be arranged between the pull rope 21 and the valve plug, and the pull rope 21 is retracted inwards to pull the tension spring hook, so that the valve plug in the sealing cavity 11 is pulled away, and the sealing cavity 11 is opened; when the pull cord 21 has no tension, the elastic member rebounds and drives the valve plug to return to the initial state, thereby closing the sealing cavity 11.

Since the pull cord 21 is usually a flexible member, for connection between the pull cord 21 and the drain valve assembly 1, for example, the pull cord 21 may be directly tied to the drain valve assembly 1 or fixed to the drain valve assembly 1 by a screw connection, or a structure such as a connection lug or a connection post may be provided on the drain valve assembly 1 to connect the pull cord 21, so that connection between the pull cord 21 and the drain valve assembly 1 can be achieved in the above manner.

As shown in fig. 1, 4 and 5, the pulling rope 21 extends in a second direction, which is the L2 direction shown in fig. 1; then, when the draw string 21 pulls the drain valve assembly 1 in the second direction, the valve plug moves in the first direction to open and close the seal chamber 11, and the drain valve assembly 1 is easily subjected to the up-down unbalance force due to the height difference between the first direction and the second direction, resulting in tilting itself.

As shown in fig. 1, 4 and 5, the first direction is parallel to the second direction, so that the pulling force of the pull rope pulling the drain valve assembly is parallel to the pulling force direction of the valve plug, the force transmission direction is not changed, the force loss is only the moment loss caused by the height difference between the first direction and the second direction, so that the force loss is smaller, the pulling force of the pull rope pulling the drain valve assembly can be used for pulling the valve plug more, the lost force is converted into unbalanced force of the drain valve assembly, and the inclination degree of the drain valve assembly can be reduced.

According to the embodiment of the utility model, the sealing cavity extends along the first direction, the pull rope extends along the second direction, and the first direction and the second direction have a height difference, so that 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, namely the valve plug has a space for moving the valve plug in the first direction, and the pulling force of the pull rope along the second direction acts on the valve plug to drive the valve plug to move along the first direction due to the fact that the first direction is parallel to the second direction, so that the sealing cavity is opened. The sealing cavity of the embodiment of the utility model 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 reduced, so that the height of the drain valve assembly is not limited by the height of a pull rope of the tractor, the tractors with different heights can be matched, the tractor is matched with a plurality of types of tractors, and the installation compatibility of the drain valve assembly and the tractor is improved; the outlet and the drain valve subassembly intercommunication of clothing treatment facility, then when the installation, the complete machine height of clothing treatment facility also can be along with the reduction of drain valve subassembly height and corresponding reduction to can satisfy the market and take the clothing to the requirement that clothing treatment facility whole height reduces, convenience of customers, the high reduction of clothing treatment facility can also reduce commodity circulation transportation cost simultaneously, the dress cabinet volume when promoting commodity circulation transportation.

In some embodiments, as shown in fig. 1, 4 and 5, the drain valve assembly 1 includes a body 12 and a pull rod 13. Wherein, the body 12 is internally provided with a sealing cavity 11; 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 through elastic pieces such as a tension spring hook and the like and are connected with the valve plug along the axis of symmetry of the valve plug, the pull rod 13 is pulled by the pull rope 21 which is retracted inwards, and the valve plug in the sealing cavity 11 is pulled by the pull rod 13 through the tension spring hook to open the sealing cavity 11. Wherein, the hookup location of pull rod 13 and stay cord 21 is higher than the central point of sealed chamber 11, namely the hookup location of pull rod 13 and valve plug, the hookup location of pull rod 13 and valve plug is located the extending direction of the symmetry axis of sealed chamber 11, then, when installing drain valve subassembly 1, can reduce the installation height of drain valve subassembly 1, make the symmetry axis of sealed chamber 11 extend along first direction setting, and the symmetry axis of sealed chamber 11 is less than the hookup location of pull rod 13 and stay cord 21, make the height of drain valve subassembly 1 no longer receive the height of stay cord 21 of tractor 2, and when drain valve subassembly 1 is connected with other structures of clothing processing equipment, other structures can be along with drain valve subassembly 1 installation height's reduction and corresponding reduction.

For example, the distance between the guide 3 and the lower ends of the pull rod 13 and the valve cover 14 is smaller than 1/2 of the distance between the guide 3 and the upper ends of the pull rod 13 and the valve cover 14, and then the distance between the guide 3 and the lower ends of the pull rod 13 and the valve cover 14 is smaller than 1/3 of the integral distance between the upper ends and the lower ends of the pull rod 13 and the valve cover 14. The guide piece is arranged at the positions of the pull rod and the valve cover, which are close to the lower end, respectively, the connecting position of the valve plug and the pull rod is positioned at the central position of the pull rod, and the connecting position of the pull rope and the pull rod is positioned above the central position of the pull rod, so that the arrangement of the guide piece is not easy to influence the connection of the valve plug and the pull rod and the connection of the pull rope and the pull rod.

In some embodiments, as shown in fig. 1, 4 and 5, the guide 3 is a guide rail 31 protruding from the surface of the pull rod 13 and a groove 32 provided in the valve cover 14; alternatively, the guide 3 is a groove 32 provided in the pull rod 13 and a guide rail 31 protruding from the surface of the valve cover 14.

The embodiment of the utility model further limits the shape of the valve cover, so that the structure of the cover-shaped part, the pull rod and the protruding part after being installed is more compact.

In some embodiments, as shown in fig. 1, 4 and 5, the laundry treating apparatus further includes a clutch assembly 4, and the operating principle of the clutch assembly 4 can be understood as: the clutch is a key component of the pulsator type full-automatic washing machine, and has the main functions of transmitting the power of the motor to the clutch through the transmission function of the V-belt after the motor is started, and the clutch can realize low-speed rotation during washing and rinsing and high-speed rotation during dehydration and execute braking action at the end of dehydration. The action of the speed reducing clutch is controlled by the drainage electromagnet, and the speed reducing clutch has two states of washing and dewatering. During washing, the motor runs, the rotating speed is reduced through the speed reduction clutch to drive the impeller to intermittently rotate in the forward and reverse directions for washing, and the washing and dehydrating barrel does not rotate at the moment; during dehydration, the motor is operated, the clutch is used for driving the washing and dehydrating barrel to operate without decelerating (namely, at a high speed) to perform dehydration, and the impeller is also operated along with the washing and dehydrating barrel.

The current full-automatic pulsator washing machine generally uses a speed reducing clutch, and the structure of the speed reducing clutch mainly comprises a pulsator shaft, a dehydration shaft, elastic members such as torsion springs, a brake disc, a shifting fork, a clutch shifting lever, a ratchet wheel, a pawl, a clutch sleeve, an outer sleeve shaft, a gear shaft and the like. The washing barrel and the pulsator are respectively connected with a ratchet wheel, and the shifting fork is used for being abutted with the ratchet wheel so as to control the working state of the corresponding ratchet wheel. Specifically, when the washing barrel or the pulsator rotates, and the shifting fork is in a matched state with the ratchet wheel, the shifting fork limits the rotation of the ratchet wheel, so that the washing barrel or the pulsator cannot synchronously rotate. When the shifting fork and the ratchet wheel are in a disengaged state, the shifting fork can not limit the rotation of the ratchet wheel, so that the washing barrel and the pulsator synchronously rotate. The fork abuts against the clutch lever 42 to enable the fork to be driven to swing. The brake disc is connected with the clutch deflector rod 42 and is used for controlling the movement of the washing barrel; the elastic member 43 abuts against the clutch lever 42, so that the clutch lever 42 and the fork can be elastically restored. Thus, when the pull rod 13 is pulled to move by the tractor 2, the clutch deflector rod 42 is forced to swing, so that the brake disc moves to release the locked washing barrel. And the clutch shifting lever 42 swings to push the shifting fork to swing, so that the shifting fork can be separated from the ratchet wheel along with the increase of the swinging range of the shifting fork, the shifting fork does not limit the rotation of the ratchet wheel any more, and the washing barrel and the pulsator synchronously rotate. Meanwhile, in the process of swinging the shifting fork and the clutch shifting lever 42, the elastic piece 43 is driven to elastically deform, so that after the acting force generated by the tractor 2 is removed, the shifting fork and the clutch shifting lever 42 can be reset to the initial state under the acting force generated when the elastic piece 43 resets itself, and the state of being matched with the ratchet wheel is restored after the shifting fork resets.

As shown in fig. 1, 4 and 5, when the retractor 2 is operated, the pull rope 21 is contracted inward and pulls the pull rod 13, and the clutch assembly 4 is moved with the pull rod 13 to switch the operation modes of the laundry treating apparatus, which include a washing mode and a dehydrating mode. In the washing mode, the driving devices such as a motor and the like operate and drive the clutch assembly 4 to rotate through the transmission belt, the tractor 2 does not act, and the pull rope 21 is in a loose state, so that the brake disc and the clutch assembly 4 do not act, the pawl is always in a state of being inserted into a ratchet wheel, and the impeller shaft of the clutch assembly 4 drives the impeller to rotate, so that a washing function is realized; in the drain valve assembly 1, when the retractor 2 is not activated, the seal chamber 11 is closed, and no drain is performed. In the dehydrating mode, the pull rope 21 of the tractor 2 is tensioned, so that the brake disc and the clutch lever are driven to act, and the pawl and the ratchet wheel are separated. The impeller shaft and the dewatering barrel of the clutch assembly 4 are simultaneously in a working state, so that a dewatering function is realized; with the drain valve assembly 1, the retractor 2 is activated and the seal chamber 11 is in an open state, enabling drainage.

The clothes treatment equipment provided by the embodiment of the utility model further comprises the clutch assembly, the clutch assembly is moved along with the pull rod to switch the working mode of the clothes treatment equipment, the tractor does not act in a washing mode, the pull rope is in a loose state, and at the moment, the clutch assembly only drives the impeller to rotate, so that the washing function is realized; the sealing cavity is in a closed state, and no water is discharged. In the dehydration mode, the stay cord of the tractor is tensioned, and the clutch assembly can drive the pulsator and the dehydration barrel to rotate at high speed at the same time, so that the dehydration function is realized; the sealing cavity is in an open state under the pulling of the pull rod, so that water can be drained. The opening and closing of the sealing cavity and the working mode of the clothes treatment equipment are synchronously controlled through the pull rope, so that the storage of water flow during washing and the smooth discharge of water flow during dehydration are ensured.

As shown in fig. 1, 4 and 5, the clutch assembly 4 includes a clutch body 41, a clutch lever 42, and an elastic member 43. The clutch body 41 is used for switching an operation mode, for example, a washing mode or a dehydrating mode.
