[0063] In view of the current technical problem that the lint in the air inlet duct is difficult to clean and affects the drying effect, the present invention proposes a clothes processing device and a control method thereof, which can simply, conveniently and effectively clean the lint in the air inlet duct to ensure the drying effect. Below, the clothes processing device and the control method of the present invention are described in detail in conjunction with the accompanying drawings.

[0064] Embodiment 1

[0065] The clothes processing device of this embodiment mainly includes a controller, an outer drum 10, an inner drum, a drying duct, a cleaning component, a flushing pipeline, a drainage pipeline, etc. Figures 1 to 3 shown.

[0066] The outer cylinder 10 is arranged in the box body, and has a water discharge port 11 , an air outlet 12 , and an air inlet 13 .

[0067] The inner cylinder is arranged in the outer cylinder 10 . The inner cylinder is coaxially arranged with the outer cylinder 10 and is rotatably connected with the outer cylinder 10 .

[0068] The drying air duct includes an air inlet duct 21 and an air outlet duct 22. One end of the air inlet duct 21 has an air inlet 21-1, and the other end of the air inlet duct 21 has an air outlet 21-2. The air duct wall of the air inlet duct 21 also has a water inlet 21-3; the positions of the water inlet 21-3 and the air outlet 21-2 are both higher than the position of the air inlet 21-1. The air inlet 21-1 of the air inlet duct 21 is connected to the air outlet 12 of the outer cylinder 10, the air outlet 21-2 of the air inlet duct 21 is connected to the air inlet 22-1 of the air outlet duct 22, and the air outlet 22-2 of the air outlet duct 22 is connected to the air inlet 13 of the outer cylinder 10.

[0069] A drying device and a fan FAN are arranged in the air outlet duct 22. The fan FAN rotates to drive the air in the outer cylinder 10 into the air inlet duct 21, and then into the air outlet duct 22. After being dried by the drying device, the air enters the space between the outer cylinder 10 and the inner cylinder through the outer cylinder air inlet 13, and then enters the inner cylinder.

[0070] The cleaning assembly includes a power unit and a cleaning unit 32; the cleaning unit 32 contacts the inner peripheral wall of the air inlet duct 21, and the cleaning unit 32 can move along the length direction of the air inlet duct 21 under the drive of the power unit. When the cleaning unit 32 moves, the lint in the air inlet duct 21 and on the inner peripheral wall of the air inlet duct 21 can be cleaned. For example, when the cleaning unit 32 moves in a direction close to the air inlet 21-1 of the air inlet duct 21, the cleaning unit 32 pushes the lint to the air inlet 21-1.

[0071] The flushing pipeline includes a water inlet pipe 41 and a water inlet valve V1 disposed on the water inlet pipe 41; the water inlet pipe 41 is connected to the water inlet 21-3 of the air inlet duct 21. When the water inlet valve V1 is opened, water in the water inlet pipe 41 enters the air inlet duct 21 to flush the air inlet duct 21.

[0072] The drainage pipeline includes a drainage pipe 42 and a drainage valve disposed on the drainage pipe 42; the drainage pipe 42 is connected to the drainage port 11 of the outer tub 10. When the drainage valve is opened, the water in the outer tub 10 enters the drainage pipe 42 from the drainage port 11 and then is discharged from the clothing processing device. A drainage pump PUMP is also disposed on the drainage pipe 42. When the drainage pump is started, the water in the outer tub 10 is quickly discharged through the drainage pipe 42.

[0073] The controller controls the operation of the power unit, the water inlet valve V1, the drain valve, the drain pump, and the operation of the entire laundry processing device.

[0074] When the clothing processing equipment meets the cleaning conditions, the controller sends a control signal to the power unit, and the power unit controls the cleaning unit 32 to move along the length direction of the air inlet duct 21 to the air inlet 21-1 of the air inlet duct 21, pushes the lint to the air inlet 21-1, and then controls the water inlet valve V1 and the drain valve to open, and the drain pump starts, and the water in the water inlet pipe 41 enters the air inlet duct 21 to flush the air inlet duct 21. The flushing water and lint enter the outer drum 10 through the air inlet 21-1, and then enter the drain pipe 42 from the drain port 11, and then are discharged through the drain pipe 42.

[0075] The clothing processing device of this embodiment is designed so that the cleaning part 32 contacts the inner wall of the air inlet duct 21, and the cleaning part 32 can move along the length direction of the air inlet duct 21 under the drive of the power part, so that the lint in the air inlet duct 21 can be pushed to the air inlet 21-1 of the air inlet duct 21; by designing a water inlet 21-3 on the air duct wall of the air inlet duct 21, the water inlet 21-3 is connected to the water inlet pipe 41, when the water inlet valve is opened, the water in the water inlet pipe 41 enters the air inlet duct 21 to flush the air inlet duct 21; the flushing water and lint enter the outer drum 10 through the air inlet 21-1, and then enter the drain pipe 42 from the drain port 11 and are discharged through the drain pipe 42. Therefore, the clothing processing device of this embodiment accumulates the lint in the air inlet duct 21 at the air inlet 21-1 through the cleaning section 32, and then the water in the water inlet pipe 41 enters the air inlet duct 21 through the water inlet 21-3, flushes the air inlet duct 21, flushes away the lint, and discharges it in time through the drain pipe, thereby achieving simple, convenient and effective cleaning of the lint in the air inlet duct and ensuring the drying effect, thereby solving the technical problem in the prior art that the lint in the air inlet duct is difficult to clean and affects the drying effect.

[0076] In some embodiments of the present application, the air inlet duct 21 is arranged vertically, and the air outlet duct 22 is arranged horizontally.

[0077] The air inlet 21-1 of the air inlet duct 21 is located at the bottom of the air inlet duct 21, and the opening of the air inlet 21-1 faces downward; the air outlet 21-2 of the air inlet duct 21 is located at the top of the air inlet duct 21, and the air outlet 21-2 is a horizontal opening, and the opening faces the air outlet duct 22; the water inlet 21-3 of the air inlet duct 21 is opened on the top wall of the air inlet duct 21, and the opening of the water inlet 21-3 faces the air inlet 21-1 of the air inlet duct 21.

[0078] The air inlet 21 - 1 of the air inlet duct 21 is connected to the air outlet 12 of the outer tube 10 through a first transition pipe 23 ; the air outlet 22 - 2 of the air outlet duct 22 is connected to the air inlet 13 of the outer tube 10 through a second transition pipe 24 .

[0079] After the water in the water inlet pipe 41 enters the air inlet duct 21 through the water inlet 21-3, it can rush vertically downward to the air inlet 21-1 with a large impact force, and can quickly and smoothly flush the wire scraps accumulated at the air inlet 21-1 into the first transition pipe 23, then into the outer tube 10, and finally discharged through the drain pipe 42.

[0080] In some embodiments of the present application, the power unit includes a motor M and a connector 31; the motor M is located outside the air inlet duct 21, and the output shaft of the motor M extends transversely into the air inlet duct 21; the output shaft of the motor M is away from the air inlet 21-1 of the air inlet duct 21. The motor M is fixed to the outer wall of the air inlet duct 21, and the output shaft of the motor is close to the air outlet 21-2 of the air inlet duct 21. The output shaft of the motor is flush with the air outlet 21-2 of the air inlet duct 21, or the position of the output shaft of the motor is higher than the position of the air outlet 21-2.

[0081] The connecting member 31 is wound around the output shaft of the motor M, and one end of the connecting member 31 is connected to the output shaft of the motor M, and the other end of the connecting member 31 is connected to the cleaning portion 32 .

[0082] The controller controls the motor M to rotate in a first direction (such as forward rotation), lowers the connecting member 31, and the number of windings of the connecting member 31 on the motor output shaft is reduced. The cleaning portion 32 moves toward the air inlet 21-1 of the air inlet duct 21 (moves downward) under the action of its own gravity, moves to the air inlet 21-1 of the air inlet duct 21, and pushes the wire scraps to the air inlet 21-1. Figure 1 shown.

[0083] The controller controls the motor M to rotate in a second direction (such as reverse rotation), tightens the connecting member 31, and increases the number of windings of the connecting member 32 on the motor output shaft. Driven by the connecting member 31, the cleaning portion 32 moves in a direction away from the air inlet 21-1 of the air inlet duct 21 (moves upward) and moves to the top of the air inlet duct 21, such as near the air outlet 21-2, see Figure 2 , Figure 3 shown.

[0084] The second direction is opposite to the first direction.

[0085] By designing the power part of the above structure, the connection member 31 can be lowered and tightened by rotating the motor M, so that the cleaning part 32 is moved closer to or farther away from the air inlet 21-1. The structure is simple, the control is convenient, and it is easy to implement.

[0086] The connector 31 can be a rubber tube or a steel wire rope, as long as it can be wound around the motor output shaft.

[0087] In some other embodiments of the present application, a reel is rotatably arranged in the air inlet duct, the connecting member is wound around the reel, one end of the connecting member 31 is connected to the reel, and the other end of the connecting member 31 is connected to the cleaning portion 32. The output shaft of the motor M is connected to the reel to drive the reel to rotate, thereby realizing the lowering and tightening of the connecting member.

[0088] In some other embodiments of the present application, the power unit includes an electric telescopic rod; one end of the electric telescopic rod is connected to the top wall of the air inlet duct, and the other end of the electric telescopic rod is connected to the cleaning unit. The controller controls the extension and retraction of the electric telescopic rod.

[0089] The controller controls the electric telescopic rod to extend, driving the cleaning part 32 to move toward the air inlet 21 - 1 of the air inlet duct 21 , and moves to the air inlet 21 - 1 of the air inlet duct 21 ; thereby pushing the lint to the air inlet 21 - 1 .

[0090] The controller controls the electric telescopic rod to shorten, driving the cleaning part 32 to move in a direction away from the air inlet 21 - 1 of the air inlet duct 21 , and move to the top of the air inlet duct 21 , such as near the air outlet 21 - 2 .

[0091] By designing the electric telescopic rod, the electric telescopic rod can drive the cleaning part 32 to approach or move away from the air inlet 21 - 1 when it is extended and retracted, and the structure is simple and easy to control.

[0092] In some embodiments of the present application, the cleaning portion 32 is made of an elastic material (such as rubber) to avoid damaging the inner peripheral wall of the air inlet duct 21. The cleaning portion 32 has a through hole along its axial direction to facilitate the passage of water. The outer peripheral wall of the cleaning portion 32 contacts the inner peripheral wall of the air inlet duct 21, so as to facilitate pushing the wire scraps on the inner peripheral wall of the air inlet duct 21 to the air inlet 21-1.

[0093] For example, the cleaning portion 32 is a circular rubber pad, and a soft brush is provided on its outer peripheral surface. The soft brush contacts the inner peripheral wall of the air inlet duct to facilitate cleaning of the air inlet duct.

[0094] The clothing processing device of this embodiment may be a washing machine, a washing and drying machine, etc.

[0095] Embodiment 2

[0096] Based on the clothes processing device of the first embodiment, the second embodiment proposes a clothes processing device control method.

[0097] Specifically, the controller of the clothes processing device executes the clothes processing device control method of the second embodiment.

[0098] The control method of the clothes processing device of this embodiment mainly includes the following steps: Figure 4 shown.

[0099] When the cleaning conditions are met, the cleaning procedure is performed.

[0100] Step S11: In the cleaning procedure, the cleaning unit is controlled to move to the air inlet of the air inlet duct.

[0101] The cleaning part is controlled to move along the length direction of the air inlet duct toward the air inlet of the air inlet duct, and moves to the air inlet 21 - 1 of the air inlet duct 21 to push the wire scraps to the air inlet 21 - 1 .

[0102] Step S12: Control the water inlet valve and the drain valve to open, so that the water in the water inlet pipe flushes the air inlet duct, and the flushed water is discharged through the drain pipe.

[0103] After the water inlet valve V1, the drain valve and the drain pump are opened, the water in the water inlet pipe 41 enters the air inlet duct 21 to flush the air inlet duct 21. The flushing water and thread scraps enter the outer drum 10 through the air inlet 21-1, and then enter the drain pipe 42 from the drain port 11, and then are discharged from the clothing processing equipment through the drain pipe 42.

[0104] The control method of the clothing processing equipment of the present embodiment controls the cleaning part to move to the air inlet of the air inlet duct during the cleaning procedure, so that the lint in the air inlet duct accumulates at the air inlet of the air inlet duct, and controls the water inlet valve and the drain valve to open, so that the water in the water inlet pipe flushes the air inlet duct, flushes away the lint, and discharges it in time through the drain pipe, thereby achieving simple, convenient and effective cleaning of the lint in the air inlet duct and ensuring the drying effect, thereby solving the technical problem in the prior art that the lint in the air inlet duct is difficult to clean and affects the drying effect.

[0105] In some embodiments of the present application, the control method further includes: in the cleaning procedure, the water inlet valve and the drain valve are closed after being opened for a set time, and the cleaning part is controlled to move in a direction away from the air inlet of the air inlet duct. Figure 5 shown.

[0106] Step S21: In the cleaning procedure, the cleaning unit is controlled to move to the air inlet of the air inlet duct.

[0107] Step S22: Control the water inlet valve and the drain valve to open, so that the water in the water inlet pipe flushes the air inlet duct, and the flushed water is discharged through the drain pipe.

[0108] Step S23: the water inlet valve and the drain valve are opened for a set time and then closed, and the cleaning part is controlled to move in a direction away from the air inlet of the air inlet duct until it moves to the air outlet of the air inlet duct.

[0109] By designing steps S21 to S23, after flushing the air inlet duct, the cleaning part is controlled to move in a direction away from the air inlet of the air inlet duct to avoid affecting the gas flow in the air inlet duct during drying.

[0110] In some other embodiments of the present application, the control method further includes: in the cleaning procedure, after the cleaning unit moves to the air inlet of the air inlet duct and before the water inlet valve and the drain valve are opened, the cleaning unit is controlled to move in a direction away from the air inlet of the air inlet duct, and then the water inlet valve and the drain valve are controlled to close after opening for a set period of time. Figure 6 shown.

[0111] Step S31: In the cleaning procedure, the cleaning unit is controlled to move to the air inlet of the air inlet duct.

[0112] Step S32: Control the cleaning unit to move in a direction away from the air inlet of the air inlet duct, until it moves to the air outlet of the air inlet duct.

[0113] Step S33: Control the water inlet valve and the drain valve to open, so that the water in the water inlet pipe flushes the air inlet duct, and the flushed water is discharged through the drain pipe.

[0114] Step S34: the water inlet valve and the drain valve are opened for a set time and then closed.

[0115] By designing steps S31 to S34, after the cleaning part moves to the air inlet of the air inlet duct and before the water inlet valve and the drain valve are opened, the cleaning part is controlled to move in the direction away from the air inlet of the air inlet duct, that is, after pushing the lint to the air inlet of the air inlet duct, the cleaning part moves to the air outlet of the air inlet duct, and then the water inlet valve and the drain valve are opened to prevent the cleaning part from obstructing the flow of water and affecting the flushing of the air inlet duct.

[0116] In some embodiments of the present application, when the power unit includes a motor and a connecting member, the motor is located outside the air inlet duct, and the output shaft of the motor extends laterally into the air inlet duct; the output shaft of the motor is away from the air inlet of the air inlet duct; the connecting member is wrapped around the output shaft of the motor, and one end of the connecting member is connected to the output shaft of the motor, and the other end of the connecting member is connected to the cleaning unit.

[0117] Controlling the cleaning part to move to the air inlet of the air inlet duct specifically includes: controlling the motor to rotate in a first direction (such as forward rotation), lowering the connecting piece, and the cleaning part moves toward the direction close to the air inlet of the air inlet duct (moves downward) under the action of its own gravity, and moves to the air inlet of the air inlet duct.

[0118] Controlling the cleaning part to move in a direction away from the air inlet of the air inlet duct specifically includes: controlling the motor to rotate in a second direction (such as reverse rotation), tightening the connecting member, and driven by the connecting member, the cleaning part moves in a direction away from the air inlet of the air inlet duct (moves upwards). Move to the air outlet of the air inlet duct.

[0119] The second direction is opposite to the first direction.

[0120] The connection piece can be lowered and tightened by rotating the motor M, so that the cleaning part is moved closer to or farther away from the air inlet. The structure is simple, the control is convenient, and the implementation is easy.

[0121] In some other embodiments of the present application, when the power unit includes an electric telescopic rod, one end of the electric telescopic rod is connected to the top wall of the air inlet duct, and the other end of the electric telescopic rod is connected to the cleaning unit.

[0122] Controlling the cleaning part to move to the air inlet of the air inlet duct specifically includes: controlling the electric telescopic rod to extend, driving the cleaning part to move toward the air inlet of the air inlet duct, and moving to the air inlet of the air inlet duct.

[0123] Controlling the cleaning part to move in a direction away from the air inlet of the air inlet duct specifically includes: controlling the electric telescopic rod to shorten, driving the cleaning part to move in a direction away from the air inlet of the air inlet duct, and moving to the air outlet of the air inlet duct.

[0124] The cleaning portion 32 is driven and controlled to be close to or away from the air inlet 21 - 1 by the electric telescopic rod when being extended or retracted, so the structure is simple and the control is convenient.

[0125] In some embodiments of the present application, when any of the following conditions is met, it is determined that the cleaning condition is met and the cleaning procedure is executed;

[0126] Condition 1: Before the rinse cycle;

[0127] Condition 2: After the rinsing process is completed;

[0128] Condition 3: Before the last dehydration of the drying program.

[0129] That is, before water enters the rinsing program, after the rinsing program ends, and before the last dehydration of the drying program, the cleaning conditions are met and the cleaning program is executed, thereby ensuring that the lint and lint in the air inlet duct are flushed to the drain pipe before entering the drying process to avoid clogging the air duct.

[0130] Before the rinsing program begins, the cleaning program is performed. In the cleaning program, the water inlet valve, the drain valve, and the drain pump are opened for a first set time (eg, 10 seconds) and then closed.

[0131] When the rinsing program is finished, the cleaning program is executed. In the cleaning program, the water inlet valve, the drain valve, and the drain pump are opened for a first set time (such as 10 seconds) and then closed.

[0132] Before the last dehydration of the drying program, the water is first drained to the empty barrel level, and then the cleaning program is performed; in the cleaning program, the water inlet valve, the drain valve, and the drain pump are opened for the second set time (such as 2 minutes) and then closed.

[0133] The second set duration>the first set duration.

[0134] The control method of the clothing processing device of the present embodiment solves the problem of incomplete drying due to excessive lint and thread scraps during washing and drying, thereby improving product competitiveness.

[0135] The control method of the clothing processing equipment in this embodiment is aimed at the characteristics of small lint, especially pet hair. After washing, the cleaning part is used to clean the hair. After the cleaning part reaches the bottom of the air inlet duct, the water inlet valve, the drain valve, and the drain pump are opened to flush away the accumulated hair, which is convenient for cleaning the hair and lint, improves the drying rate, and eliminates user complaints.

[0136] The specific process of the control method of the clothes processing device is described below in conjunction with the accompanying drawings. Figure 7 shown.

[0137] The user places the clothes inside the washing machine, selects the washing and drying program and starts it. Before the last dehydration, drain the water to the empty barrel level, then control the motor to rotate forward, and the connector extends downward. The end of the connector is provided with a cleaning part (round rubber pad). After the cleaning part pushes all the lint in the air inlet channel to the air inlet at the bottom of the air inlet duct, open the water inlet valve, drain valve, and drain pump, and continue to wash and drain for 2 minutes to prevent the washed lint from entering the inner drum and contacting the clothes again. After the cleaning is completed, the motor rotates in the opposite direction, driving the connector to retract upward and return to the initial position (the air outlet of the air inlet duct). At the same time, in order to predict in advance that lint and lint will enter the air inlet duct, after each rinse, the water inlet valve, drain valve, and drain pump are all opened for 10S, and the water in the water inlet pipe enters the air inlet duct through the water inlet valve to clean the air inlet duct and avoid the risk of lint and lint adhesion in advance. See. Figure 7 shown.

[0138] Step S41: Execute a washing procedure.

[0139] Step S42: Before the rinsing procedure begins, a cleaning procedure is performed. In the cleaning procedure, the cleaning unit moves to the air inlet of the air inlet duct, and the water inlet valve, the drain valve, and the drain pump are opened for a first set time (eg, 10 seconds) and then closed.

[0140] Step S43: Before the last dehydration of the drying process, drain the water to the empty tub water level.

[0141] Step S44: Execute a cleaning procedure. In the cleaning procedure, the cleaning unit moves to the air inlet of the air inlet duct, and the water inlet valve, the drain valve, and the drain pump are opened for a second set time (such as 2 minutes) and then closed.

[0142] Step S45: Enter the drying stage.

[0143] Through the joint action of rinse prediction + water inlet valve + drain valve and drain pump, it is executed according to the prescribed timing logic to ensure that the pet hair and lint in the drum are flushed to the drain pipe before entering the drying process, avoiding hair and lint blocking the air duct, solving the problem of clothes not being fully dried, and improving the user experience.

[0144] This drying program control method for cleaning pet hair uses a motor to drive the cleaning part to accumulate hair debris at the bottom of the air inlet duct. The water inlet valve, drain valve and drain pump work together to interfere with the rinsing program in advance, avoiding hair and lint blocking the air duct, solving the problem of clothes not being fully dried, improving user experience and increasing product competitiveness.
