Background

Washing apparatuses for washing laundry, such as washing machines, cause lint to be dropped and mixed into washing water during washing of the laundry due to friction between the laundry and the laundry, and between the laundry and the washing machine itself. If the lint in the washing water cannot be removed, the lint is likely to adhere to the surface of the laundry after the washing is completed, which may affect the washing effect of the laundry. For this reason, a conventional washing machine is provided with a filter for filtering lint, and the lint is removed from the washing water by continuously passing the washing water through the filter during washing.

As shown in fig. 4 to fig. 15, the present embodiment is a further limitation of the specific structure of the switching device 800 in the first embodiment.

Specifically, a first valve plug 841 is disposed inside the first valve body 840 of the switching device 800, and the first valve plug 841 controls the first inlet 8401 to alternatively communicate with the first outlet 8402 and the third outlet 8403 through movement. The second valve body 850 is internally provided with a second valve plug 851, and the second valve plug 851 moves to control the on-off between the second inlet 8501 and the second outlet 8502.

The switching device 800 also includes a drive member and a transmission mechanism.

Therefore, the flow direction of the filtered clean water can be alternatively controlled through one driving motor 862 or the on-off state between the sewage outlet 6103 and the recovery device 500, on one hand, the number of driving elements required to be arranged for controlling the on-off of the water path in the washing device can be saved, thereby reducing the production cost, and on the other hand, the control logic for simplifying the on-off of the water path is also facilitated.

In a specific embodiment of this embodiment, the driving member includes a driving wheel 861, and the transmission mechanism includes two sets of transmission components, namely a first transmission component in transmission connection with the first valve plug 841 and a second transmission component in transmission connection with the second valve plug 851. The first transmission assembly converts rotation of the driver 861 in a first direction (i.e., clockwise rotation as indicated by the solid arrow in fig. 11) into movement of the first valve plug 841, and the second transmission assembly converts rotation of the driver 861 in a second direction (i.e., counterclockwise rotation as indicated by the dashed arrow in fig. 11) into movement of the second valve plug 851.

The drive assembly in this embodiment includes at least a drive wheel 870 and a one-way drive 880. The driving wheel 861 is in transmission connection with the transmission wheel 870, and rotates together with the driving wheel 861 through the transmission wheel 870, so as to drive the one-way transmission member 880 to rotate or keep still. Alternatively, the driving wheel 861 may be in transmission connection with the one-way transmission member 880, and rotate together with the driving wheel 861 through the one-way transmission member 880, so as to drive the transmission wheel 870 to rotate or keep stationary.

As shown in fig. 9 and 10, the driving wheel 870 has an annular structure, and the one-way transmission 880 is coaxially disposed inside the annular structure. Specifically, the central region of the upper surface of the driving wheel 870 is recessed to form a cavity for receiving the one-way transmission member 880, and the periphery of the cavity forms an annular structure. The bottom wall of the cavity can axially limit the one-way transmission member 880 to ensure a stable fit between the drive wheel 870 and the one-way transmission member 880.

Preferably, the stop surface 8702 forms an angle with the inner circumferential wall 8704 that is less than 90 degrees and the relief surface 8703 forms an angle with the inner circumferential wall 8704 that is greater than 90 degrees.

The one-way transmission member 880 includes a transmission body 8801 and a pusher body 8802 fixedly disposed on the peripheral wall of the transmission body 8801. The outer circumferential wall of the transmission body 8801 is spaced from the inner circumferential wall 8704 of the annular structure, and the pusher body 8802 extends obliquely from the outer circumferential wall of the transmission body 8801 to the inner circumferential wall 8704 of the annular structure of the transmission wheel 870.

Preferably, the included angle between the pushing surface 8803 and the inner peripheral wall 8704 is complementary to the included angle between the stop surface 8702 and the inner peripheral wall 8704, so that when the pushing surface 8803 is stopped against the stop surface 8702, the pushing surface and the inner peripheral wall can be completely attached to each other, and a better transmission effect is achieved.

The side of pushing body 8802 facing inner peripheral wall 8704 of the annular structure has a sliding surface 8804, and when one-way transmission member 880 rotates counterclockwise relative to transmission wheel 870, sliding surface 8804 can slide along release surface 8703 of stop 8701, so that transmission wheel 870 remains stationary without rotating with one-way transmission member 880.

Preferably, the pusher body 8802 extends in an arcuate direction such that the sliding surface 8804 is a convex arcuate surface. The release surface 8703 of the stopping portion 8701 is a concave cambered surface matched with the sliding surface 8804, so that sliding friction force generated between the sliding surface 8804 and the release surface 8703 can be reduced as much as possible, and the transmission wheel 870 can be kept static when the one-way transmission member 880 rotates counterclockwise.

In a further version of this embodiment, as shown in fig. 7, 8 and 12, the first transmission assembly comprises at least a first transmission wheel 871 and a first one-way transmission member 881 coaxially arranged, and a first output wheel 843 for transmitting power to the first valve plug 841. The second transmission assembly comprises at least a second transmission wheel 872 and a second one-way transmission member 882, coaxially arranged, and a second output wheel 853 for transmitting power to the second valve plug 851.

Specifically, the first one-way transmission member 881 and the driving wheel 861 are coaxially disposed, located above the driving wheel 861, and drivingly connected to the driving wheel 861 through a circumferential limiting structure, so that the driving wheel 861 and the first one-way transmission member 881 synchronously rotate. The first driving wheel 871 is positioned on the upper side of the first one-way driving element 881, and the first output wheel 843 is arranged on the left side of the periphery of the first driving wheel 871, is in transmission connection with the first driving wheel 871 and can rotate along with the first driving wheel 871.

The second transmission wheel 872 is disposed on the right side of the periphery of the driving wheel 861, and is in transmission connection with the driving wheel 861 and can rotate along with the driving wheel 861. Second one-way driving medium 882 is located the second drive wheel 872 upside, and second output wheel 853 and the coaxial setting of second one-way driving medium 882 are located second one-way driving medium 882 upside, are connected with second one-way driving medium 882 transmission through circumference limit structure, make second output wheel 853 and the synchronous rotation of second one-way driving medium 882.

In the above scheme, the pushing surfaces 8803 of the pushing bodies 8802 on the first one-way transmission member 881 and the second one-way transmission member 882 face opposite directions, so that the driving wheel 861 can alternatively drive the first output wheel 843 or the second output wheel 853 to rotate when rotating in different directions.

Through the above positional relationship, the second output wheel 853 is located on the right side of the outer periphery of the first driving wheel 871, and the first output wheel 843 is disposed coplanar with the upper side surface of the second output wheel 853. First output wheel 843 and second output wheel 853 are used for the transmission to first valve plug 841 and second valve plug 851 respectively, set up first output wheel 843 and second output wheel 853 as the symmetry relatively first transmission wheel 871, and then switching device 800 forms symmetrical structure more easily, makes its overall structure more regular, the installation of switching device 800 in washing equipment of being convenient for.

In detail, a lower side surface of the first one-way transmission member 881 is provided with a raised external spline 8811, the driving wheel 861 is provided with an internal spline 8611 matched with the external spline 8811, and the external spline 8811 is inserted into the internal spline 8611, so that the driving wheel 861 and the first one-way transmission member 881 can rotate synchronously. The surface sets up bellied external splines on the upside of second one-way drive spare 882, set up on the second output wheel 853 with internal spline 8532 that external splines match, during external spline on the second one-way drive spare 882 inserted internal spline 8532, can make second output wheel 853 rotate along with second one-way drive spare 882 is synchronous.

The drive motor 862 is disposed below the drive wheel 861 and has an output 8621 projecting upward. The middle portion of the first one-way transmission member 881 is provided with an internal spline 8812 matching with the output end 8621, the center of the driving wheel 861 is provided with a hole, and the output end 8621 passes through the driving wheel 861 and is inserted into the internal spline 8812. The driving motor 862 directly drives the first unidirectional transmission member 881 to generate movements in different directions, and drives the driving wheel 861 to rotate synchronously therewith.

Taking the orientation shown in fig. 8 as an example, the driving motor 862 drives the first one-way transmission member 881 to rotate counterclockwise, so as to drive the first transmission wheel 871 to rotate counterclockwise synchronously, and further drive the first output wheel 843 to rotate clockwise, so as to generate a motion of the first valve plug 841 drivingly connected thereto. The driving wheel 861 rotates synchronously with the first one-way transmission member 881 to drive the second transmission wheel 872 on the right side to rotate clockwise. At this time, the second one-way transmission member 882 does not rotate with the second transmission wheel 872 and remains stationary, so that the second output wheel 853 is also stationary without moving the second valve plug 851.

When the driving motor 862 drives the first one-way transmission member 881 to rotate clockwise, the first transmission wheel 871 does not rotate with the first one-way transmission member 881 and remains stationary, so that the first output wheel 843 is also in a stationary state without moving the first valve plug 841. The driving wheel 861 rotates synchronously with the first one-way transmission member 881 to drive the second transmission wheel 872 on the right side to rotate anticlockwise, so as to drive the second one-way transmission member 882 to rotate anticlockwise synchronously, so that the second output wheel 853 on the upper side of the second one-way transmission member rotates anticlockwise synchronously, and the second valve plug 851 is driven to move.

The second output wheel 853 is arranged at the right side of the first transmission wheel 871, but the outer periphery thereof is not provided with a gear structure and is not subjected to the transmission action of the first transmission wheel 871.

In another scheme of this embodiment, a belt transmission mode can be adopted between the driving wheel and the second transmission wheel, and between the first transmission wheel and the first output wheel, and the same effect can be achieved. However, it should be noted that, since the transmission directions of the two transmission modes of the gear transmission and the belt transmission are opposite, the pushing surfaces of the pushing bodies on the first unidirectional transmission member and the second unidirectional transmission member are required to be set to the same direction, so that when the driving wheel rotates in different directions, one of the first output wheel and the second output wheel can be selected to drive the first output wheel or the second output wheel to rotate.

In a further aspect of this embodiment, a first valve plug 841 is reciprocally disposed within the first valve body 840 to communicate/disconnect the first inlet 8401 with the first outlet 8402. To effect the transmission of the first output wheel 843 to the first valve plug 841, the first transmission assembly further includes a first link 842 connected to the first output wheel 843. The first connection rod 842 extends along a reciprocating direction of the first valve plug 841, one end of which is connected with the first valve plug 841 and the other end of which is provided with a first slideway 8421 extending along a direction perpendicular to the first connection rod 842. The first protrusion 8431 is eccentrically disposed on the surface of the first output wheel 843 facing away from the driver 861, and the first protrusion 8431 is slidably disposed in the first sliding groove 8421.

The first output wheel 843 rotates to make the first protrusion 8431 slide along the first sliding way 8421 in a reciprocating manner, and simultaneously, the first sliding way 8421 can be driven to move in a reciprocating manner along the extending direction of the first connecting rod 842, so that the first valve plug 841 is driven to move in a reciprocating manner in the first valve body 840.

Similarly, a second valve plug 851 is reciprocatably disposed inside the second valve body 850 to connect/disconnect communication between the second inlet 8501 and the second outlet 8502. The second transmission assembly further includes a second connecting rod 852 connected to the second output wheel 853, the second connecting rod 852 extending in a reciprocating direction of the second valve plug 851, one end being connected to the second valve plug 851, and the other end being provided with a second slide 8521 extending in a direction perpendicular to the second connecting rod 852. The surface of the second output wheel 853 facing away from the driving wheel 861 is eccentrically provided with a second protrusion 8531, and the second protrusion 8531 is slidably disposed in the second slide track 8521.

The second output wheel 853 rotates to make the second protrusion 8531 slide along the second slide track 8521, and at the same time, drives the second slide track 8521 to reciprocate along the extending direction of the second connecting rod 852, thereby driving the second valve plug 851 to reciprocate in the second valve body 850.

Therefore, the problem that the first output wheel 843 and the second output wheel 853 rotate smoothly due to the fact that the contact area of the first slide 8421 and the first output wheel 843 or the second slide 8521 and the second output wheel 853 are in direct contact with each other and the friction force is increased due to the fact that the contact area of the first slide 8421 and the second slide 8521 is too large is solved.

In a specific embodiment of this embodiment, the first valve body 840 has a certain extension length along the moving direction of the first valve plug 841, the third outlet 8403 is disposed on the left end wall of the first valve body 840, and the first inlet 8401 and the first outlet 8402 are disposed on the side wall of the first valve body 840. Along the length extension of the first valve body 840, the first inlet 8401 is located between the first outlet 8402 and the third outlet 8403.

Preferably, the first inlet 8401 and the first outlet 8402 are staggered in the circumferential direction of the first valve body 840 to increase the distance between the first inlet 8401 and the first outlet 8402, so that the first inlet 8401 and the first outlet 8402 are respectively connected to corresponding pipeline structures without causing mutual influence.

The first inlet 8401 and the first outlet 8402 are both located between the switching portion 8411 and the first sealing portion 8413, and are in a conductive state. After the water in the water container 100 is filtered by the filter 600 and enters the first valve 840, the water can flow out of the first outlet 8402 and return to the water container 100.

When the washing apparatus drains water, the first valve plug 841 is driven to move rightward, so that the switching portion 8411 is separated from the left end wall of the first valve body 840, and the third outlet 8403 is opened. The switching portion 8411 finally moves between the first inlet 8401 and the first outlet 8402 such that the communication between the first inlet 8401 and the first outlet 8402 is cut off while the third outlet 8403 is communicated with the first inlet 8401. After entering the first valve 840 after being filtered by the filter 600, the water in the water container 100 flows out of the third outlet 8403 and is discharged through the outer discharge pipe 250.

The right end of the first valve body 840 is provided with a first valve cover 845 to seal the inside of the first valve body 840, and the first connecting rod 842 passes through the first valve cover 845 to be connected with the first sealing portion 8413 of the first valve plug 841. The first valve body 840 is partitioned into two spaces, which are not communicated with each other, at the left and right sides by the first sealing portion 8413, so that water does not enter the space at the right side of the first sealing portion 8413. The condition that leaks has appeared in the position of having avoided first connecting rod 842 to pass first valve gap 845 on the one hand, and on the other hand makes the installation environment of first connecting rod 842 be anhydrous environment, also can avoid the line bits of aquatic etc. to filter miscellaneous pair and cause the winding to first connecting rod 842, and then influences the problem of first valve plug 841 smooth and easy motion in first valve body 840.

The second connection portion 8512 has a pillar-shaped structure, and a side surface of the second connection portion 8512 is spaced apart from an inner surface of a sidewall of the second valve body 850.

Referring to fig. 4, 13 and 14, during the circulation filtering process of the washing apparatus, the second valve body 850 is cut off between the second inlet 8501 and the second outlet 8502 by the second valve plug 851, so that the filter device 600 cannot be drained outwardly from the sewage outlet 6103. Specifically, the second valve plug 851 is positioned at the leftmost end in the second valve body 850, and the blocking portion 8511 abuts against the left end wall of the second valve body 850 to block the second outlet 8502.

When the filter device 600 discharges the sewage, the second valve plug 851 is driven rightward, so that the blocking portion 8511 is separated from the left end wall of the second valve body 850, and the second outlet 8502 is opened. The blocking portion 8511 finally moves to the right of the second inlet 8501, so that the second inlet 8501 is communicated with the second outlet 8502, and the sewage carrying the filtered impurities in the filtering apparatus 600 can be discharged through the sewage outlet 6103.

A second valve cap 855 is provided at a right end of the second valve body 850 to seal the inside of the second valve body 850, and a second link 852 is connected to a second sealing portion 8513 of the second valve plug 851 through the second valve cap 855. The second valve body 850 is partitioned into left and right two spaces by the second sealing portion 8513, which are not communicated with each other, so that water does not enter the space on the right side of the second sealing portion 8513. The condition that the position that second connecting rod 852 passed through second valve cover 855 has been avoided on the one hand to appear leaking makes the installation environment of second connecting rod 852 be anhydrous environment, also can avoid the filter impurities such as thread scraps of aquatic to cause the winding to second connecting rod 852, and then influences the problem that second valve plug 851 smoothly moved in second valve body 850.

Further, in the present embodiment, the first valve body 840 and the second valve body 850 are integrally connected by the valve body connecting portion 804 having a plate-shaped structure, so that the overall structure of the switching device 800 is more stable. Preferably, the first valve body 840, the second valve body 850 and the valve body connecting part 804 are integrally formed. As shown in fig. 5, the switching device 800 is fixed to the plate-like portion 22 by a valve body connecting portion 804.

In a further aspect of this embodiment, the switching device 800 further provides a mounting structure for securing the transmission mechanism.

The right ends of the first link 842 and the second link 852 are disposed between the second mounting plate 802 and the third mounting plate 803, so that the first sliding way 8421 and the second sliding way 8521 are correspondingly sleeved on the first protrusion 8431 and the second protrusion 8531. The second mounting plate 802 is provided with a guide portion 8021 facing the surface of the third mounting plate 803, the guide portion 8021 forms a guide channel, and the first link 842 and the second link 852 are respectively limited in the guide channel formed by the corresponding guide portion 8021.

In this embodiment, the switching device 800 can output two driving forces in different directions through a driving motor 862 by transmission of the transmission mechanism, so as to alternatively drive the first plug 841 or the second plug 851 to move, thereby alternatively changing the communication state of the first valve body 840 or the second valve body 850. The first valve body 840 and the second valve body 850 are respectively connected to waterway structures of the washing device for realizing different functions, thereby realizing the control of the on-off state of different waterway structures by one driving motor 862. By reducing the use of driving elements in the washing equipment, the cost is reduced, the installation space is saved, and meanwhile, only the direction of the driving force output by the driving motor 862 needs to be controlled, so that the control logic of the on-off of the complex water path is simplified.

EXAMPLE III

This embodiment provides a method for controlling a washing apparatus as described in the second embodiment.

With reference to fig. 4 to 15, the control method includes:

the driving motor 862 rotates towards the first direction, the first valve plug 841 is driven to move through the transmission mechanism, the on-off state of the circulating filter pipeline is changed, and the second valve plug 851 is kept static;

the driving motor 862 rotates in a second direction opposite to the first direction, and drives the second valve plug 851 to move through the transmission mechanism, so as to change the on-off state of the sewage pipeline 240, and the first valve plug 841 remains stationary.

Taking the orientations shown in fig. 6 and 11 as examples, the first direction in this embodiment is a clockwise direction shown by a solid arrow in fig. 11, and the second direction is a counterclockwise direction shown by a dashed arrow in fig. 11.

In the above scheme, the rotation direction of the driving motor 862 is controlled to select the on-off state of the circulating filter pipeline and the sewage pipeline 240, and the control logic is simple and feasible.

In this embodiment, the switching device 800 has at least three operating states, i.e., a circulation filtering state, a draining state and a draining state. Wherein, in the circulating filtration state, the first inlet 8401 is communicated with the first outlet 8402, so that the circulating filtration pipeline is communicated; in a drainage state, the first inlet 8401 is communicated with the third outlet 8403, so that the water containing cylinder 100 is communicated with the outer discharge pipeline 250; in the sewage discharging state, the second inlet 8501 and the second outlet 8502 are communicated, thereby communicating the sewage discharging line 240. In the circulation filtering state and the drain state, communication between the second inlet 8501 and the second outlet 8502 of the second valve body 850 is shut off by the second valve plug 851.

The control method of the washing equipment comprises the following steps: the driving motor 862 rotates in a first direction to drive the first valve plug 841 through the transmission mechanism, so as to switch the switching device 800 between the circulation filtering state and the drainage state.

In the embodiment of the present invention, in the initial state, the switching device 800 switches on the circulation filtering pipeline of the washing apparatus and switches off the drainage pipeline 240. That is, the switching device 800 in this embodiment is in the loop filter state in the normal state.

The control method of the washing equipment specifically comprises the following steps:

s11, in an initial state, the switching device 800 conducts the circulating and filtering pipeline;

s12, the washing equipment receives a drainage instruction, the driving motor 862 rotates towards the first direction, and the switching device 800 is switched to a drainage state;

s13, the draining process is finished, the driving motor 862 rotates again to the first direction, and the switching device 800 returns to the circulation filtering state.

Further, in step S12, after the switching device 800 is switched to the drainage state, the driving motor 863 stops rotating, the circulating pump 400 is controlled to be turned on, and the water in the water bucket 100 is driven to flow to the external drainage pipeline 250, so as to complete the drainage process of the washing machine.

In a further aspect of this embodiment, in order to determine whether the first valve plug 841 is moved to the right position when the switching device 800 is switched between the circulation filtering state and the draining state, thereby controlling the timing of stopping the rotation of the driving motor 862, the switching device 800 is provided with a first position switch 844 for detecting the movement position of the first valve plug 841.

Specifically, two first triggering portions for triggering the first position switch 844 are provided on the first valve plug 841 or the transmission mechanism, and the two first triggering portions respectively correspond to the circulation filtering state and the drainage state of the switching device. During operation of the drive motor 862 in a first direction, it is determined that the first spool 841 is in position if a signal is received that the first position switch 844 is triggered.

The corresponding control method comprises the following steps: in step S12 and step S13, when the signal that the first position switch 844 is triggered is received, the drive motor 862 stops rotating.

In detail, as shown in fig. 13 to 15, the first trigger part is a concave structure provided on a sidewall of the first link 842 (only the first trigger part corresponding to the drainage state is shown in the figures). A first position switch 844 is provided on the second mounting plate 802 on the side of the first link 842.

In one embodiment of this embodiment, the first position switch 844 is a touch switch having a micro-blade in contact with a sidewall of the first link 842. In the process of switching the switching device 800 from the circulation filtration state shown in fig. 13 to the drainage state shown in fig. 15, the micro blade is always in contact with the first link 842. When the first link 842 moves to the rightmost end position shown in fig. 15, the concave structure on the first link 842 corresponds to the position of the micro-moving piece, and the micro-moving piece is no longer in contact with the first link 842, which generates a signal that the first position switch 844 is triggered, and at this time, controls the driving motor 862 to stop rotating.

Similarly, the micro-motion plate is always in contact with the first link 842 during the switching of the switching device 800 from the drainage state shown in fig. 15 to the circulation filtration state shown in fig. 13. When the first link 842 moves to the leftmost position shown in fig. 13, the position of the micro-moving plate just corresponds to another concave structure (not shown) on the first link 842, so that the micro-moving plate is no longer in contact with the first link 842, that is, a signal that the first position switch 844 is triggered is generated, and at this time, the driving motor 862 is controlled to stop rotating.

In another embodiment of this embodiment, the first position switch 844 is a photoelectric sensor, and can detect the light signal and receive the time required for the reflected signal, so as to determine the distance to the front shield. In the process of switching the switching device 800 from the circulation filtering state shown in fig. 13 to the drainage state shown in fig. 15, the time required for the first position switch 844 to receive the reflected signal is constant because the distance between the first position switch 844 and the side wall of the first link 842 is constant. When the first link 842 moves to the rightmost end position shown in fig. 15, the concave structure on the first link 842 corresponds to the position of the first position switch 844, and further the distance between the first position switch 844 and the sidewall of the first link 842 increases, so that the time required for receiving the reflected signal changes suddenly, that is, a signal that the first position switch 844 is triggered is generated, and at this time, the driving motor 862 is controlled to stop rotating.

Similarly, the time required for the first position switch 844 to receive the reflected signal is constant throughout the process of the switch 800 switching from the drain state shown in fig. 15 to the loop filter state shown in fig. 13. When the first link 842 moves to the leftmost position shown in fig. 13, the position of the first position switch 844 just corresponds to another concave structure (not shown) on the first link 842, so that the time required for receiving the reflected signal changes suddenly, that is, a signal that the first position switch 844 is triggered is generated, and at this time, the driving motor 862 is controlled to stop rotating.

In the above solution, only one first position switch 844 is disposed in the switching device 800, and the two first triggering portions disposed on the first link 842 are used to detect whether the first valve plug 841 is moved to the right position in two operating states, i.e., the circulation filtering state and the draining state of the switching device 800. Meanwhile, the switching device 800 is switched to different working states, and the feedback signal is the same when the first position switch 844 is triggered.

The arrangement mode can reduce the use number of the detection elements on one hand, and is favorable for saving cost. On the other hand, the driving motor 862 does not need to determine the operation state to which the switching device 800 is to be switched, and the control logic is simpler as long as the driving motor stops rotating upon receiving the signal that the first position switch 844 is triggered.

In this embodiment, in order to realize the operation of discharging the sewage from the filtering apparatus 600, the control method further includes the following steps:

s21, in an initial state, the switching device 800 cuts off the sewage discharge pipeline 240;

s22, the washing equipment receives a sewage discharge instruction, drives the motor 862 to rotate towards the second direction, and conducts the sewage discharge pipeline 240;

s23, the blowdown process is finished, and the driving motor 862 rotates to the second direction again, and the blowdown pipeline 240 is cut off.

Preferably, in step S22, after the switching device 800 switches to the sewage draining state, i.e., turns on the sewage draining pipeline 240, the circulation pump 400 is controlled to be turned on, so as to drive the sewage in the filtering device 600 to be drained.

In the above scheme, the circulating pump 400 is not only used for the circulating filtration process and the drainage process of the washing equipment, but also provides driving force in the sewage disposal process of the filtering device 600, and does not need to add extra power, so that the sewage carrying the filtering impurities in the filtering device 600 can be fully discharged in the sewage disposal process, and the residue of the filtering impurities is reduced.

In a further aspect of this embodiment, in order to determine whether the second valve plug is moved to the proper position when the switching device 800 switches on and off the sewage pipeline 240, so as to control the timing when the driving motor 862 stops rotating, the switching device 800 is provided with a second position switch 854 for detecting the movement position of the second valve plug 851.

Specifically, two second triggering portions for triggering the second position switch 854 are disposed on the second valve plug 851 or the transmission mechanism, and the two second triggering portions respectively correspond to the on state and the off state of the sewage pipeline 240. During the operation of the driving motor 862 rotating in the second direction, if a signal indicating that the second position switch 854 is triggered is received, it is determined that the second valve plug 851 is moved into position.

The corresponding control method comprises the following steps: in step S22 and step S23, the driving motor 862 stops rotating when the signal that the second position switch 854 is triggered is received.

As shown in fig. 13 to 15, the second trigger portion is a concave structure provided on a sidewall of the second link 852 (only the second trigger portion corresponding to the drainage state is shown in the drawings), similar to the first trigger portion. The second position switch 854 is provided on the second mounting plate 802 on the side of the second link 852.

In this embodiment, the second position switch 854 can be one of a touch switch or a photoelectric sensor.

In the case where the second position switch 854 is a touch switch, when the second link 842 is at any position between the leftmost end and the rightmost end, the micro-piece of the touch switch contacts the side wall of the second link 842. When the second link 842 moves to the leftmost end or the rightmost end, the concave structure causes the micro-strip of the touch switch to be released without contacting the second link 842, so as to generate a signal that the second position switch 854 is triggered, and at this time, the driving motor 862 is controlled to stop rotating.

In the case where the second position switch 854 is a light sensor, when the second link 842 is at any position between the leftmost end and the rightmost end, the time required for the second position switch 854 to receive the reflected signal is always constant. When the second link 842 moves to the leftmost end or the rightmost end, the distance between the second position switch 854 and the second link 852 changes suddenly due to the concave structure, and further, the time required for receiving the reflected signal changes suddenly, that is, a signal for triggering the second position switch 854 is generated, and at this time, the driving motor 862 is controlled to stop rotating.

In the above solution, the switching device 800 can detect whether the second valve plug 851 is moved to the right position in the two working states of the switching device 800, i.e. the on state and the off state of the sewerage pipeline 240, through a second position switch 854, and the feedback signal generated when the second position switch is triggered is the same in both cases. On one hand, the number of detection elements is reduced, the cost is reduced, and on the other hand, the control logic can be simplified.

In this embodiment, the filtering apparatus 600 performs at least one blowdown operation during the washing process of the washing machine.

Example four

With reference to fig. 4 to fig. 15, the present embodiment is different from the third embodiment in that: in an initial state, the switching device 800 switches on the water containing barrel 100 and the outer discharge pipeline 250, and switches off the sewage discharge pipeline 240. That is, in the present embodiment, the switching device 800 is in the drainage state in the normal state.

The method for controlling the washing equipment in the embodiment specifically comprises the following steps:

s11', in an initial state, the switching device 800 conducts the water containing barrel 100 and the external discharge pipeline 250;

s12', the washing equipment receives a circulating filtering instruction, the motor 862 is driven to rotate towards the first direction, and the switching device 800 is switched to a circulating filtering state;

s13', the circulation filtering process is finished, the driving motor 862 rotates again in the first direction, and the switching device 800 returns to the drainage state.

Further, in step S12', after the switching device 800 switches to the circulation filtering state, the driving motor 863 stops rotating, and controls the circulation pump 400 to start, so as to drive the water in the water containing barrel 100 to circulate through the filtering device 600, thereby completing the circulation filtering process of the washing device.

In this embodiment, the scheme of determining whether the first valve plug 841 moves in place is the same as that in the third embodiment, and is not repeated.

EXAMPLE five

As shown in fig. 1 to 17, the present embodiment is further limited to the first embodiment, and the recovery device 500 is disposed inside the water tank 310 of the detergent dispensing device 300.

Specifically, the water tank 310 communicates with the water containing barrel 100, and the recovery device 500 includes a lint collecting assembly 560 provided inside the water tank 310. The lint collecting assembly 560 receives the sewage discharged from the filtering apparatus 600, filters the sewage, collects the filtered impurities in the sewage, and the filtered water enters the water tank 310.

The sewage discharged from the filtering apparatus 600 is received by the lint collecting assembly 560, the lint collecting assembly 560 can filter the sewage to collect the filtered impurities therein inside the lint collecting assembly 560, and the filtered water from which the filtered impurities are removed can be discharged into the water tank 310 and then into the water container 100 through the discharge port 302 for the subsequent washing process of the washing machine or discharged along with the water discharge flow of the washing machine.

In above-mentioned scheme, recovery unit 500 accessible thread scraps collection assembly 560 filters the sewage of receiving to filter impurity and separation of water, the user of being convenient for clears up the filtration impurity in recovery unit 500, has avoided filtering impurity and water to mix together, and the user is difficult to the problem of handling it. The filtered impurities are collected by the lint collecting unit 560, and the water without the filtered impurities can be introduced into the water containing tub 100 through the water tank 310 of the detergent dispenser 300. The water flow introduced into the recovery device 500 can be discharged in real time, the volume of the recovery device 500 does not need to be too large, and the problem of overflow of the recovery device 500 is avoided.

Further, the lint collecting assembly 560 includes a filter frame 561 and a filter screen. Wherein, filter frame 561 detachably installs in the bottom region in basin 310, forms the open side's of upside line bits collection chamber, the uncovered of line bits collection chamber is used for receiving the sewage that filter equipment 600 discharged, sets up delivery port 562 on filter frame 561. The filter screen covers delivery port 562 at least to filter the sewage that is received, collect the filter impurity such as thread scraps in the thread scraps collection chamber.

In this embodiment, delivery port 562 sets up at least on the diapire of filter frame 561, can discharge after filtering the water that gets into in the thread scraps collection assembly 560 to the at utmost, avoids the thread scraps to collect the sewage residue of intracavity. The inner side of the bottom wall 311 of the water tank 310 is provided with a plurality of convex supporting parts 321 at intervals corresponding to the installation position of the filter frame 561, and the supporting parts 321 are supported below the filter frame 561, so that the bottom wall of the filter frame 561 and the bottom wall 311 of the water tank 310 are arranged at intervals.

Specifically, the support portion 321 may be two or more support ribs disposed at intervals, and support the filter frame 561 at a position spaced from the bottom wall 311 of the water tank 310, so that the bottom wall of the filter frame 561 is not in direct contact with the bottom wall 311 of the water tank 310. The arrangement mode can prevent the problem that the sewage in the thread scrap collecting cavity cannot be filtered and flows out through the water outlet 562 in time because the water outlet 562 on the bottom wall of the filter frame 561 is shielded by the bottom wall 311 of the water tank 310.

In the preferred scheme of this embodiment, the water outlets 562 are further disposed on a plurality of side walls of the filter frame 561, and a plurality of water outlets 562 are disposed on the bottom wall and the side walls of the filter frame 561. By increasing the number of the water outlets 562, the water outlet area of the lint collecting assembly 560 can be increased, and the filtering and discharging efficiency of the lint collecting assembly on the received sewage can be improved. Therefore, the problem that when the flow of sewage discharged by the filtering device 600 is large, the sewage overflows from the upper opening of the thread scrap collecting cavity to cause the filtered impurities to enter the water tank 310 can be avoided.

In a further scheme of this embodiment, a limit baffle 322 extending upward is disposed inside the bottom wall 311 of the water tank 310, and the limit baffle 322 is disposed vertically. The bottom wall 311 of the water tank 310 is partially inclined to form an inclined wall 312 opposite to the limit baffle 322, and the distance between the inclined wall 312 and the limit baffle 322 gradually increases from bottom to top. The filter frame 561 is limited between the limit baffle 322 and the inclined wall 312.

In the above scheme, the filter frame 561 is limited by the cooperation of the limiting baffle 322 and the inclined wall 312, so that the filter frame 561 can be more stably installed in the water tank 310, and especially under the condition of a large sewage flow, the problem that the filter frame 561 is knocked over by the impact of water flow to cause failure of the filtering effect on sewage can be avoided.

In this embodiment, a dispenser box for containing a detergent is further provided in the sump 310, and the dispenser box is provided in the sump 310 in an insertable/extractable manner. The dispenser box is drawn out of the water bath, and serves to remove the lint collecting assembly 560 from the water bath 310, thereby cleaning the filtered foreign substances collected therein.

In a further embodiment of the present invention, a sewage inlet 301 communicated with a sewage outlet 6103 of the filtering apparatus 600 is disposed on the water tank 310, a sewage flow channel 330 communicated with the sewage inlet 301 is disposed inside the water tank 310, and the sewage discharged from the filtering apparatus 600 is conveyed to the recycling apparatus 500 through the sewage flow channel 330. The upper side of the recovery device 500 has an opening (i.e., the opening of the lint collection chamber in the assembly of the lint collection assembly 560) that is disposed below the outlet end of the sewage flow path 330.

Specifically, the detergent dispenser 300 has a certain extension length, the sewage inlet 301 is disposed near one end of the detergent dispenser 300, and the lint collecting assembly 560 is disposed in a middle region of the water tank 310 in the detergent dispenser 300 along the extension direction of the length of the detergent dispenser 300. The sewage flow channel 330 drains the sewage entering from the sewage inlet 301 to the middle of the water tank 310, and the sewage water flows out from the water outlet end of the sewage flow channel 330 after reaching the water outlet end and falls into the lint collecting assembly 560 below.

In a preferred embodiment of the present invention, the detergent dispensing device 300 extends from a region near the front sidewall 12 to a region near the rear sidewall 16 in the second installation space N. The filter device 600 is disposed in the first installation space M in a region near the rear wall 16, and the drain inlet 301 is disposed in a region near the rear wall 16 of the detergent dispenser 300 in order to facilitate the engagement with the filter device 600.

In the above solution, the filtering device 600 and the sewage inlet 301 of the detergent putting device 300 are disposed close to the rear sidewall 16 of the cabinet 10, so as to further shorten the distance between the sewage outlet 6103 of the filtering device 600 and the sewage inlet 301 of the detergent putting device 300, and further simplify the arrangement of the sewage pipeline 240.

In another preferred scheme of this embodiment, the filtering device may be further disposed in an area close to the front side wall of the box body in the first installation space, and accordingly, the sewage inlet is correspondingly disposed in an area close to the front side wall of the box body on the detergent dispensing device, and the distance between the sewage outlet of the filtering device and the sewage inlet of the detergent dispensing device can be shortened.

In this embodiment, the recycling device 500 is disposed inside the water tank of the detergent dispenser 300, and does not occupy additional installation space, so that the structure of the washing apparatus is compact. Recovery unit 500 can filter sewage to separation filtration impurity wherein and collect, the user of being convenient for clears up, simultaneously, because recovery unit 500 does not establish ties on the loop filter pipeline, even it is blockked up by filtration impurity, can not cause the loop filter pipeline yet and is cut off, leads to the problem that the loop filter process is forced to stop.

Example six

As shown in fig. 4 and 18 to 21, the present embodiment is different from the fifth embodiment in that: the lint collecting assembly 560 is mounted to the dispenser housing 340.

Specifically, a distributor box 340 capable of being inserted/drawn out is arranged inside the water tank 310, a detergent adding cavity 341 and a recycling installation cavity 342 which are isolated from each other are formed on the distributor box 340, and the detergent adding cavity 341 and the recycling installation cavity 342 are respectively and independently communicated with the water tank 310. A lint collection assembly 560 is mounted within the recovery mounting chamber 342.

In the above-mentioned solution, the front end of the dispenser box 340 is provided with a handle 345 for a user to grasp, the lint collecting assembly 560 can be inserted into/drawn out of the water tank 310 along with the dispenser box 340, and preferably, the lint collecting assembly 560 is detachably disposed inside the recycling mounting cavity 342, so that the user can draw out the dispenser box 340 and remove the lint collecting assembly 560 for cleaning, and the operation is convenient.

In this embodiment, at least two detergent adding cavities 341 are disposed on the dispenser box 340, and are respectively located at the upper and lower sides of fig. 19, wherein the upper detergent adding cavity 341 is shorter than the lower detergent adding cavity 341, and a recycling installation cavity 342 is disposed at the right end of the upper washing detergent adding cavity 341.

In this embodiment, the lint collecting assembly 560 specifically includes a filtering bracket 560 and a filtering net, and the filtering bracket 560 forms a relatively closed filtering cavity for receiving the sewage discharged from the filtering apparatus 600. The filtering bracket 560 is provided with a sewage inlet 564 and a plurality of water outlets 562, and a filter screen at least covers the water outlets 562 for filtering the received sewage.

In the above scheme, sewage enters the inside of the filtering cavity formed by the filtering bracket 563 through the sewage inlet 564, and only flows out through the filter screen covering the water outlet 562, so that the filtering effect is ensured to the maximum extent, and the condition that sewage enters the water tank 310 without passing through the filter screen is avoided.

In a further aspect of this embodiment, a partition 343 is provided on the dispenser box 340 to form a detergent addition chamber 341 and a recovery installation chamber 342 which are partitioned from each other. The water outlet 562 is provided on the upper side surface of the filtering bracket 563, and the upper side of the separation barrier 543 is higher than at least the upper side surface of the filtering bracket 563.

When the filtered water flows out from the water outlet 562 positioned on the upper side surface of the filtering bracket 563, because the height of the isolating baffle 543 is higher, the filtered water cannot go over the isolating baffle 543 to enter the detergent adding cavity 341, so that pollution to the detergent contained in the detergent adding cavity 341 is avoided, or because the recycling installation cavity 342 overflows to enter the detergent adding cavity 341, the detergent in the detergent adding cavity 341 is put into the water containing barrel 100 at an incorrect washing stage.

Further, the recycling installation cavity 342 is defined by an isolation baffle 343 and an overflow plate 344, the upper side of the overflow baffle 344 is lower than the isolation baffle 343, and water flowing out of the water outlet 562 enters the recycling installation cavity 342 and can overflow from the upper side of the overflow baffle 344 into the water tank 310, so as to be introduced into the water containing barrel 100.

In the preferred scheme of this embodiment, all set up delivery port 562 on the upper and lower both sides surface of filtering support 563, the sewage that gets into all can flow out after the filter screen filters by upper and lower both sides, has improved the filtration efficiency of thread scraps collection component 560 to sewage. Similarly to the fifth embodiment, the mesh number of the filter net holes is not smaller than that of the filter net holes for filtering in the filtering device 600, so as to ensure that all the filtering impurities in the sewage can be intercepted.

In this embodiment, the water tank 310 extends along the insertion/extraction movement direction of the dispenser box 340, the left end is open for the dispenser box 340 to extend outwards, the right end is closed, and the right end of the water tank 310 is provided with a sewage inlet 301 communicated with a sewage outlet 6103 of the filtering device 600. The lint collecting unit 560 is inserted into/withdrawn from the water tank 310 with the distributor box 340, and the sewage inlet 564 of the filtering bracket 563 is provided at a right end position of the distributor box 340.

When the lint collecting assembly 560 is inserted into the sink 310 along with the dispenser box 340, the sewage inlet 564 is hermetically connected to the sewage inlet 301. The lint collecting assembly 560 is drawn out of the sump 310 with the dispenser box 340, and the sewage inlet 564 is separated from the sewage inlet 301.

In one embodiment of this embodiment, the waste inlet 564 is inserted into the waste inlet 301 when the lint collecting assembly 560 is inserted into the sink 310 along with the dispenser box 340. The outer wall of the sewage inlet 564 and/or the inner wall of the sewage inlet 301 are/is provided with a sealing structure to realize the sealing connection between the sewage inlet 564 and the sewage inlet 301, so that sewage discharged by the filtering device 600 can flow from the sewage inlet 301 to the sewage inlet 564 to enter a filtering cavity formed by the filtering bracket 563, and the water leakage problem does not occur at the splicing part of the sewage inlet 564 and the sewage inlet 301.

EXAMPLE seven

The present embodiment is different from the sixth embodiment in that: the two sides of the distributor box along the drawing direction are respectively provided with a detergent adding cavity and a recycling installation cavity, and the detergent adding cavity and the recycling installation cavity are basically symmetrically arranged on the distributor box.

Specifically, a detergent adding cavity is formed in one side of the distributor box and used for a user to add detergent to be put into the detergent adding cavity, and a recycling installation cavity which is basically consistent with the detergent adding cavity in shape and size is formed in the other side of the distributor box. The thread scrap collecting assembly is detachably mounted in the recycling mounting cavity and is filled with the recycling mounting cavity as far as possible. The detergent adds the chamber and retrieves and to have certain interval between the installation cavity, prevents that the line bits collection subassembly from filtering the discharged water entering detergent after the sewage and adding the chamber.

Compared with the sixth embodiment, the space inside the recycling installation cavity is increased, the filtering cavity formed by the filtering bracket of the thread scrap collecting assembly has larger volume, and the efficiency of filtering the sewage by the thread scrap collecting assembly is improved. The interval between detergent adds the chamber and retrieves the installation cavity is bigger, can prevent better that the water after the sewage filters from spilling over and getting into in the detergent adds the chamber.

Example eight

The present embodiment is different from the sixth embodiment in that: the water tank is internally provided with a distributor box and a recovery mounting box respectively, the distributor box and the recovery mounting box can be inserted into/drawn out of the water tank of the detergent feeding device respectively and independently, the internal cavity of the recovery mounting box is communicated with the water tank, and the thread scrap collecting assembly is detachably mounted inside the recovery mounting box.

In this embodiment, a recycling installation box independent of the distributor box is arranged in the water tank of the detergent feeding device, and is used for installing the thread scrap collecting assembly. When the user takes out the lint collecting assembly for cleaning, the recovery mounting box can be independently withdrawn without withdrawing the dispenser box.

Furthermore, the distributor box and the recovery installation box are horizontally arranged in parallel in the water tank. Like this, when intaking in the distributor box mixes and overflows and get into the basin, the mixed solution of detergent and water can not get into the recovery mounting box, correspondingly, the line bits collection subassembly filters the discharged water of back and also can not get into the distributor box when overflowing the entering basin by retrieving the mounting box to sewage. So can guarantee can not intermix between the liquid in distributor box and the recovery mounting box, user experience is better.

Simultaneously, because distributor box and recovery mounting box set up in the basin side by side, when both are taken out simultaneously, can not cause and shelter from each other, and then can not influence the user to both respective operations.

In the embodiment, similar to the sixth embodiment, when the thread scrap collecting assembly is inserted into the water tank along with the recovery mounting box, the sewage inlet on the filtering bracket is hermetically connected with the sewage discharge inlet on the water tank; the thread scrap collecting assembly is drawn out from the water tank along with the recovery mounting box, and the sewage inlet is separated from the sewage discharge inlet.

In a concrete scheme of this embodiment, when the line bits collection assembly inserted the basin along with retrieving the mounting box, the sewage entry inserted in the blowdown entry. And sealing structures are arranged on the outer wall of the sewage inlet and/or the inner wall of the sewage inlet so as to realize the sealing connection of the sewage inlet and the sewage inlet. When the thread scrap collecting assembly is drawn out from the water tank along with the recovery mounting box, the sewage inlet is drawn out from the sewage inlet, and the sewage inlet are not communicated.

In another concrete scheme of this embodiment, the blowdown entry extends to the basin inboard and forms grafting portion, and when the line bits collection assembly inserted the basin along with retrieving the mounting box, the sewage entry cup jointed on the grafting portion. And sealing structures are arranged on the inner wall of the sewage inlet and/or the outer wall of the insertion part so as to realize the sealing connection of the sewage inlet and the insertion part. When the thread scrap collecting assembly is drawn out from the water tank along with the recovery mounting box, the insertion part is drawn out from the sewage inlet, and the thread scrap collecting assembly and the sewage inlet are not communicated.

In this embodiment, the lint collecting assembly is mounted on the recovery mounting box which is independent of the dispenser box, so that the lint collecting assembly can be independently extracted and detached for cleaning, and the dispenser box is still in a state of being inserted into the water tank, and the state of the dispenser box is not affected.
