[0002] After a clothing treatment device washes and dries clothes, etc., lint will adhere to the inner wall of the inner drum. As the lint increases, it will affect the treatment effect of the clothes.

[0003] Existing clothing treatment devices can remove lint through a drum cleaning function, but it consumes a large amount of water and electric energy and the cleaning is not timely.

[0004] Correspondingly, there is a need in the art for a new control method for a clothing treatment device, a clothing treatment device, and a control device to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above technical problems, that is, to solve the problem of high energy consumption for cleaning lint in existing clothing treatment devices.

[0006] The present invention provides a control method for a clothing treatment device. The clothing treatment device includes: a treatment drum, a treatment chamber is formed in the treatment drum; a water inlet valve, the water inlet valve is communicated with the treatment chamber; a circulation structure, the circulation structure and the treatment drum form a circulation loop; a circulation pump, the circulation pump is used to circulate liquid in the circulation loop; a lint detection device, the lint detection device is used to detect the amount of lint on the inner wall of the washing chamber; the control method includes: obtaining the amount of lint; when the amount of lint is greater than or equal to a first lint set value, controlling the water inlet valve to open; controlling the circulation pump to start; when the amount of lint is less than a second lint set value, controlling the circulation pump to close; controlling the water inlet valve to close; wherein, the second lint set value is less than or equal to the first lint set value.

[0007] In the case of adopting the above technical solution, the lint detection device timely determines whether the amount of lint exceeds the set value. When lint needs to be cleaned, the water inlet valve is controlled to open, and liquid such as water or aqueous solution enters the treatment chamber. The circulation pump pumps out the liquid in the treatment chamber and circulates it in the circulation loop. While the liquid circulates, it flushes the inner wall of the treatment drum to remove lint. The lint is quickly cleaned under the combined cleaning action of the liquid in the treatment drum and the liquid driven by the circulation pump, saving energy consumption and improving the cleaning efficiency of lint at the same time.

[0008] In the specific implementation manner of the above clothing treatment device, the step of "obtaining the amount of lint" further includes: obtaining the amount of lint after the drying program ends.

[0009] In the case of adopting the above technical solution, since a large amount of lint is easily generated during the drying process of the clothes and remains on the inner wall of the processing cylinder, it is possible to detect whether the amount of lint exceeds the first lint setting value after each drying program ends.

[0010] In the specific implementation manner of the above-mentioned clothes treatment device, before the step of "acquiring the amount of lint", the control method further includes: after the washing program ends, acquiring the number of washes; the step of "acquiring the amount of lint" further includes: when the number of washes is equal to the preset number, acquiring the amount of lint; before or at the same time as or after the step of "acquiring the amount of lint", the control method further includes: clearing the number of washes to zero.

[0011] In the case of adopting the above technical solution, after each preset number of washing programs, it is detected whether the amount of lint exceeds the first lint setting value, and the number of washes is cleared to zero each time the number of washes is equal to the preset number for re-counting.

[0012] In the specific implementation manner of the above-mentioned clothes treatment device, the clothes treatment device further includes: a lint decomposing agent dispensing device for dispensing a lint decomposing agent into the treatment chamber; before or at the same time as or after the step of "controlling the circulation pump to start", the control method further includes: controlling the lint decomposing agent dispensing device to dispense the lint decomposing agent.

[0013] In the case of adopting the above technical solution, a lint decomposing agent is dispensed into the treatment chamber, and the lint decomposing agent decomposes the lint while the water rinses the lint on the inner wall of the processing cylinder, further improving the lint cleaning effect.

[0014] In the specific implementation manner of the above-mentioned clothes treatment device, the clothes treatment device further includes: a water level detection device for detecting the water level value in the treatment chamber; after the step of "controlling the water inlet valve to open", the control method further includes: acquiring the water level value; the step of "controlling the circulation pump to start" further includes: when the water level value is greater than or equal to the first water level setting value, controlling the circulation pump to start.

[0015] In the case of adopting the above technical solution, by detecting the water level value and controlling the circulation pump to start when the water level value is greater than or equal to the first water level setting value, the situation of the circulation pump idling and starting to rotate with less liquid is avoided, improving the safety of use and further reducing energy consumption.

[0016] In the specific implementation manner of the above-mentioned clothes treatment device, the clothes treatment device further includes: a drain valve communicated with the treatment chamber; before or at the same time as or after the step of "controlling the water inlet valve to open", the control method further includes: controlling the drain valve to close.

[0017] In the case of adopting the above technical solution, the closing of the drain valve helps the liquid in the treatment cylinder to accumulate quickly, improving the efficiency of cleaning lint.

[0018] In the specific implementation manner of the above clothing treatment device, before the step of "controlling the circulation pump to close", the control method further includes: controlling the drain valve to open.

[0019] In the case of adopting the above technical solution, when the lint amount is less than the second lint set value, first control the drain valve to open, drain the liquid with lint, and at the same time keep the water inlet valve open and the circulation pump started to continue flushing the inner wall of the treatment cylinder, avoiding lint residue on the inner wall of the treatment cylinder and improving the lint cleaning effect.

[0020] In the specific implementation manner of the above clothing treatment device, the step of "controlling the circulation pump to close" further includes: when the water level value is less than the second water level set value, controlling the circulation pump to close; wherein, the second water level set value is less than or equal to the first water level set value.

[0021] In the case of adopting the above technical solution, when the water level value is less than the second water level set value, controlling the circulation pump to close avoids the situation of still rotating when the liquid is less and the circulation pump idling, improving the safety of use and further reducing the energy consumption at the same time.

[0022] In a second aspect, the present invention further provides a clothing treatment device, and the clothing treatment device includes a control device for executing the control method of the clothing treatment device.

[0023] In a third aspect, the present invention further provides a control device, and the control device includes: a processor; a memory, and the memory is adapted to store a plurality of program codes, and the program codes are adapted to be loaded and run by the processor to execute the control method of the clothing treatment device.

[0024] Compared with the prior art, the beneficial effects of the control method of the clothing treatment device provided by the present invention are: the lint detection device timely determines whether the lint amount exceeds the set value. When lint needs to be cleaned, control the water inlet valve to open, and liquids such as water or aqueous solution enter the treatment chamber. The circulation pump pumps the liquid in the treatment chamber out and circulates in the circulation loop. While the liquid circulates, it flushes the inner wall of the treatment cylinder to remove lint. The lint is quickly cleaned under the combined cleaning action of the liquid in the treatment cylinder and the liquid driven by the circulation pump, saving energy consumption and improving the lint cleaning efficiency at the same time. The clothing treatment device and the control device provided by the present invention are used to execute the control method of the clothing treatment device. Description of the Drawings

Therefore, it should not be construed as a limitation to the present invention. In addition, ordinal numbers such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Based on the problem pointed out in the background art that the energy consumption for cleaning lint in existing clothing treatment devices is large, the present invention provides a control method and a clothing treatment device for a clothing treatment device, aiming to timely determine whether the lint amount exceeds a set value through a lint detection device. When lint needs to be cleaned, the water inlet valve is controlled to open, and a liquid such as water or an aqueous solution enters the treatment chamber. The circulation pump pumps the liquid in the treatment chamber out and circulates it in the circulation loop. While the liquid is circulating, the inner wall of the treatment cylinder is rinsed to remove lint. The lint is quickly cleaned under the combined cleaning action of the liquid in the treatment cylinder and the liquid driven by the circulation pump to circulate, saving energy consumption and improving the cleaning efficiency of lint at the same time.

[0036] First, refer to Figure 1 , which shows the overall structure of the clothing treatment device. The clothing treatment device of the present invention includes a treatment cylinder 1, a water inlet valve, a circulation structure 2, a circulation pump 3, and a drain valve. A treatment chamber is formed inside the treatment cylinder 1. The treatment cylinder 1 is provided with a water inlet and a drain outlet, and the water inlet and the drain outlet are communicated with the treatment chamber; the water inlet valve is arranged at the water inlet, and the drain valve is arranged at the drain outlet; the circulation structure 2 and the treatment cylinder 1 form a circulation loop. The circulation structure 2 includes a water pipe, and the circulation pump 3 is communicated with the treatment chamber through the water pipe; the circulation pump 3 can be a centrifugal pump, a diaphragm pump, a submersible pump, etc. Optionally, a filter screen or other filtering device is provided on the suction side of the circulation pump 3, which avoids lint or other impurities in the treatment cylinder 1 from returning to the treatment cylinder 1 through the circulation structure 2 and also avoids entering the circulation pump 3 and damaging the circulation pump 3.

[0037] Possibly, the clothing treatment device further includes a spraying device 4. The spraying device 4 is arranged on the top side of the treatment chamber, and the spraying device 4 is communicated with the circulation structure 2. The circulation pump 3 pumps the liquid in the treatment cylinder 1 to the spraying device 4 through the circulation structure 2, and the liquid is sprayed from the spraying device 4 into the treatment cylinder 1.

[0038] Those skilled in the art can understand that although it is combined above with Figure 1It is described that the circulation structure 2 includes a spraying device 4 and a water pipe, but this is not restrictive. The spraying device 4 may not be provided in the circulation structure 2 either. Correspondingly, a spraying port is provided on the side wall of the treatment cylinder 1. The circulation pump 3 pumps the liquid in the treatment cavity to the spraying port, and the liquid flows back into the treatment cavity from the spraying port to achieve the circulation of the liquid. The circulation structure 2 may also be set to other structures, as long as it can form a circulation loop with the treatment cylinder 1 to achieve the circulation of the liquid, none of them deviate from the principle of the present invention and all fall within the protection scope of the present invention.

[0039] It should be noted that the clothing treatment device may be a washing machine, a dryer, a washing and drying integrated machine, etc., and no specific limitation is made here. Optionally, when the clothing treatment device is a washing machine or a washing and drying integrated machine, the treatment cylinder 1 is an inner cylinder, and an outer cylinder is provided outside the inner cylinder. A gap cavity is formed between the outer cylinder and the inner cylinder, and the gap cavity is communicated with the treatment cavity. For example, if the inner cylinder is provided with water permeable holes, the circulation pump 3 may be directly provided at the bottom of the gap cavity or on the inner wall of the outer cylinder. The circulation pump 3 is communicated with the bottom of the gap cavity through a water pipe. In this case, the outer cylinder and the water pipe together form a circulation structure. When the clothing treatment device is a dryer, the circulation pump 3 is fixedly provided on the housing of the dryer, and the circulation pump 3 is communicated with the treatment cavity through a water pipe.

[0040] The clothing treatment device further includes a lint detection device, a lint decomposing agent feeding device, and a water level detection device. The lint detection device is used to detect the amount of lint on the inner wall of the washing cavity; the lint decomposing agent feeding device is used to feed a lint decomposing agent into the treatment cavity. The lint decomposing agent may be a hair decomposing agent, keratinase, etc. The lint decomposing agent feeding device may be a detergent box and a detergent feeding pipeline. The feeding end of the detergent feeding pipeline is provided on the suction side of the circulation pump 3, which helps to fully mix the water and the lint decomposing agent. The lint decomposing agent feeding device may also be provided with a separate lint decomposing agent box and a lint decomposing agent feeding pipeline, as long as it can feed the lint decomposing agent into the treatment cavity; the water level detection device may be a water level gauge or a pressure sensor, etc., which is installed on the treatment cylinder 1 and is used to detect the water level value in the treatment cavity. In a clothing treatment device provided with an outer cylinder, the water level detection device may also be provided at the bottom of the gap cavity.

[0041] Possibly, the lint detection device can be one or several of a weight sensor, an image recognition sensor, an optical sensor, an ultrasonic sensor, and a wind speed sensor. Exemplarily, when the lint detection device is a weight sensor, the weight sensor detects the weight change of the processing cylinder 1 to obtain the weight value of the lint, thereby realizing the detection of the lint amount; when the lint detection device is an image recognition sensor, the lint amount is obtained based on the image acquired inside the processing cylinder 1. Specifically, to obtain the lint amount inside the processing cylinder 1 based on the image, it can be that image segmentation technology is used to separate the lint from the background, and the lint features in the segmented area are extracted. These features can be color, texture, shape, area size, etc.; the lint features in the segmented area are extracted, and the detected lint is quantified, including calculating the area, quantity, or other relevant dimensions of the lint; according to the known inner cylinder size, the pixel quantity of the lint is converted into an actual physical measurement. Based on the quantitative analysis of the lint, the total amount of lint in the entire inner cylinder is estimated. To obtain the lint amount inside the processing cylinder 1 based on the image, a machine learning model or a deep learning model can also be designed and trained, with the current image as the input end of the model and the lint amount as the output end of the model.

[0042] The laundry treatment device further includes a control device, which includes a processor and a memory. The memory is adapted to store multiple program codes, and the program codes are adapted to be loaded and run by the processor to execute the control method of the laundry treatment device. The processor can be a central processing unit, or other general-purpose processors, digital signal processors, application-specific integrated circuits, field-programmable gate arrays, or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or any conventional processor, etc. The memory can be an internal storage unit of the laundry treatment device, such as a hard disk or memory, etc.; the memory can also be an external storage device of the laundry treatment device, for example, a plug-in hard disk, a smart memory card, a secure digital card, a flash memory card, etc. equipped on the laundry treatment device; the memory can also include both the internal storage unit and the external storage unit of the laundry treatment device. The laundry treatment device can include multiple memories and multiple processors. Each processor executes different steps respectively. The multiple processors can be processors deployed on the same device, or processors deployed on different devices. For example, the multiple processors can be the processor on the laundry treatment device and the processor on the cloud server respectively.

[0043] Possibly, the laundry treatment device further includes a foam detection device. When the foam amount exceeds the foam set value, the control loop pump 3 is started to achieve rapid defoaming; in addition, when the processing cylinder 1 needs to be rapidly cooled, the loop pump 3 can also be started to circulate the water inside the processing cylinder 1 to achieve rapid cooling of the processing cylinder 1; furthermore, when executing a program that requires heating, such as high-temperature washing, the loop pump 3 can also be started to achieve rapid heating and uniform heating.

[0044] Then refer to Figure 2 , which shows the main steps of the control method of the clothing treatment device of the present invention, specifically including the following steps:

[0045] Step S100: Obtain the amount of lint.

[0046] Step S101: When the amount of lint is greater than or equal to the first lint setting value, control the water inlet valve to open.

[0047] Step S102: Control the circulation pump to start.

[0048] Step S103: When the amount of lint is less than the second lint setting value, control the circulation pump to close.

[0049] Step S104: Control the water inlet valve to close.

[0050] Wherein, the second lint setting value is less than or equal to the first lint setting value.

[0051] The above control method timely determines whether the amount of lint exceeds the set value through the lint detection device. When it is necessary to clean the lint, control the water inlet valve to open, and liquids such as water or aqueous solution enter the treatment chamber. The circulation pump pumps the liquid in the treatment chamber out and circulates it in the circulation loop. While the liquid is circulating, it flushes the inner wall of the treatment cylinder to remove the lint. The lint is quickly cleaned under the combined cleaning action of the liquid in the treatment cylinder and the liquid driven by the circulation pump, saving energy consumption while improving the cleaning efficiency of the lint.

[0052] Finally refer to Figure 3 , which shows the detailed steps of an implementation manner of the control method of the clothing treatment device of the present invention, specifically including the following steps:

[0053] Step S200: After the washing program ends, obtain the number of washes.

[0054] Step S201: Determine whether the number of washes is equal to the preset number. If the determination result is yes, execute step S202; if the determination result is no, execute step S200.

[0055] Step S202: Clear the number of washes to zero.

[0056] Step S203: Obtain the amount of lint.

[0057] Step S204: Determine whether the amount of lint is greater than or equal to the first lint setting value. If the determination result is yes, execute step S205; if the determination result is no, execute step S200.

[0058] Step S205: Control the drain valve to close.

[0059] Step S206: Control the inlet valve to open.

[0060] Step S207: Control the device for dispensing the hair debris decomposing agent to dispense the hair debris decomposing agent.

[0061] Step S208: Obtain the water level value.

[0062] Step S209: Determine whether the water level value is greater than or equal to the first set water level value. If the determination result is yes, execute Step S210; if the determination result is no, execute Step S208.

[0063] Step S210: Control the circulation pump to start.

[0064] Step S211: Determine whether the amount of hair debris is less than the second set hair debris value. If the determination result is yes, execute Step S212; if the determination result is no, repeat Step S211.

[0065] Step S212: Control the drain valve to open.

[0066] Step S213: Determine whether the water level value is less than the second set water level value. If the determination result is yes, execute Step S214; if the determination result is no, repeat Step S213.

[0067] Step S214: Control the circulation pump to close.

[0068] Step S215: Control the inlet valve to close.

[0069] Wherein, the second set water level value is less than or equal to the first set water level value.

[0070] By detecting the water level value, when the water level value is greater than or equal to the first set water level value, then control the circulation pump to start, and when the water level value is less than the second set water level value, control the circulation pump to close, avoiding the situation of the circulation pump idling and starting to rotate when the liquid is less, improving the safety of use, and at the same time further reducing the energy consumption.

[0071] By dispensing the hair debris decomposing agent into the treatment chamber, the hair debris decomposing agent decomposes the hair debris while the water flushes the hair debris on the inner wall of the treatment cylinder, further improving the cleaning effect of the hair debris.

[0072] It should be noted that steps S200 to S202 are applicable to be executed by laundry treatment devices such as washing machines or washer-dryers that can wash clothes. In the case where the laundry treatment device is a washer-dryer or a dryer that can dry clothes, steps S200 to S202 may not be executed, and the content of step S204 is replaced with: after the drying program ends, obtain the amount of lint; and in step S204, when the judgment result is no, execute the step "after the drying program ends, obtain the amount of lint", and those skilled in the art can adjust according to needs.

[0073] In addition, when the amount of lint is the weight value of the lint, the first lint setting value and the second lint setting value are the set thresholds of the corresponding lint weight values. When the amount of lint is the blockage percentage of the water-permeable holes, the first lint setting value and the second lint setting value are the set thresholds of the corresponding blockage percentages.

[0074] It should be noted that the above embodiments are only used to illustrate the principle of the present invention and are not intended to limit the protection scope of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above embodiments so that the present invention can be applied to more specific application scenarios.

[0075] So far, the technical solution of the present invention has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
