[0045] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and examples.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0048] Based on this, an embodiment of the present application provides a control method, a control device and a clothing processing device for a clothing processing device, which starts the compressor in advance for preheating before the end of the cleaning stage, thereby increasing the temperature in the clothing processing chamber, thereby reducing the drying time of the drying stage and improving the drying efficiency.

[0049] The control method of the embodiment of the present application is further described below in conjunction with the accompanying drawings.

[0050] Reference Figure 1 As shown, an embodiment of the present application provides a control method for a clothes processing device, the clothes processing device includes a compressor and a clothes processing chamber, and the clothes processing chamber is a structure without a drainage channel; the control method includes but is not limited to the following steps:

[0051] Step S100, executing a cleaning procedure, wherein the cleaning procedure includes a cleaning operation and a drying operation;

[0052] Step S200, determining that the cleaning operation meets the first preset time, and controlling the drying component to operate;

[0053] Step S300, determining that the operation of the drying component meets the second preset time length, and controlling the clothes processing device to perform a drying operation.

[0054] The clothing treatment device of the embodiment of the present application is used to clean and dry the clothing in the clothing treatment chamber. The clothing treatment chamber does not have a water inlet channel structure and a drainage channel structure. Different from the common washing and drying equipment, the clothing treatment device of the present application can clean the clothing in the clothing treatment chamber by introducing foam or the like, and perform a drying operation to dry the clothing after performing the cleaning operation, wherein the stage of performing the cleaning operation is correspondingly referred to as the cleaning stage, and the stage of performing the drying operation is correspondingly referred to as the drying stage. The embodiment of the present application starts the drying component for preheating before the end of the cleaning stage, and raises the temperature in the clothing treatment chamber in advance, so that after entering the drying stage, the temperature in the clothing treatment chamber can be quickly raised to the required temperature, thereby improving the drying efficiency, shortening the drying time, and thus improving the user experience. The drying component is used to increase the temperature of the clothing treatment chamber, take away the moisture in the clothing treatment chamber, and realize the drying operation of the clothing. The specific composition of the drying component is determined according to the drying method adopted by the clothing treatment device. For example, the drying component can be a heat pump system, which drives the cooling liquid through a compressor to achieve heat output, thereby heating the air sent into the clothing treatment chamber. The drying component can also be an electric heating system, etc., which are not exemplified one by one here.

[0055] It can be understood that the clothing processing device of the embodiment of the present application, its clothing processing chamber can be a drum, and the drum is driven by a motor to rotate in forward and reverse directions to shake out the clothes in the drum so that the hot air in the drying stage can blow to all the clothes in the drum.

[0056] The first preset time and the second preset time can be set according to actual conditions. The first preset time represents the cumulative running time of the cleaning operation. After reaching the first preset time, the drying component is started to run. After the drying component runs according to the second preset time, the clothes processing device is controlled to enter the drying stage. Therefore, in some cases, it can be considered that the total time of the first preset time and the second preset time is the duration of the cleaning stage; of course, the total time of the first preset time and the second preset time can also be greater than the duration of the cleaning stage, so that after the cleaning stage ends, the drying component continues for a period of time before officially entering the drying stage.

[0057] Reference Figure 2 As shown, in some embodiments, the drying component includes a compressor; the above step S200 determines that the execution of the cleaning operation meets the first preset time, and controls the operation of the drying component, including:

[0058] Step S210, determining the cumulative running time of performing the cleaning operation;

[0059] Step S220: When the accumulated operation time is greater than the first preset time, the compressor is started to run for preheating.

[0060] The accumulated running time of the cleaning operation is recorded from the start of the cleaning operation, and the clothes processing device is set to start the compressor to run and preheat in advance when the accumulated running time is greater than or equal to the preset first time. In addition, the clothes processing device of the embodiment of the present application can also determine the required time for this cleaning according to the user setting or according to the load in the clothes processing chamber, and then determine when to start the compressor for preheating according to the required time for cleaning. The clothes processing device determines the remaining cleaning time according to the accumulated running time of this cleaning and the required cleaning time. When the remaining cleaning time is less than the preset time threshold (the first preset time is equal to the required cleaning time minus the remaining cleaning time, that is, the accumulated running time), the compressor can be started for preheating, that is, a certain time is reserved for raising the temperature of the clothes processing chamber. The remaining cleaning time is variable during the cleaning stage, but usually near the end of the cleaning stage, the remaining cleaning time generally does not suddenly change, so a reasonable setting of the preset time threshold can stabilize the preheating time of the compressor.

[0061] For example, the above control method is to determine the timing of starting the compressor according to the remaining cleaning time. For example, if the preset time threshold is 1 minute, the compressor will be started one minute before the end of the cleaning stage. Since the remaining cleaning time is basically fixed to the time threshold, the specifications of the compressor are also fixed. Therefore, when the compressor is preheated and started in advance, the operating frequency of the compressor can be a fixed value, and it will run at a constant operating frequency within 1 minute of the remaining cleaning time.

[0062] In addition, during the preheating process, you can also:

[0063] Starting the compressor at a preset initial operating frequency, and increasing the operating frequency of the compressor as the remaining cleaning time decreases; or,

[0064] The compressor is started at a preset initial operating frequency, and the operating frequency of the compressor is adjusted according to the internal temperature of the laundry processing chamber.

[0065] The above two control methods start the compressor according to the initial operating frequency and adjust the operating frequency of the compressor over time. In this way, at the beginning of the washing stage, the compressor can be started and the compressor operation can be controlled at the initial operating frequency. The initial operating frequency is usually a lower frequency value, and then it can be determined how to adjust the operating frequency of the compressor according to the operating conditions of the clothing processing equipment at a subsequent time. This embodiment provides two methods of controlling the operating frequency of the compressor. The first is to adjust the operating frequency of the compressor according to the remaining cleaning time, and the second is to adjust the operating frequency of the compressor according to the internal temperature of the drum. Under the first control method, as the remaining cleaning time decreases, the operating frequency of the compressor is gradually increased. That is to say, the closer to the drying stage, the greater the operating frequency of the compressor, so that when entering the drying section, the clothing processing chamber can reach a higher preheating temperature, which is also conducive to controlling the compressor to continue to increase the operating frequency during the drying stage. In the second control mode, the temperature in the clothing processing chamber is monitored by a temperature sensor, and the operating frequency of the compressor is adjusted according to the temperature in the clothing processing chamber. For example, during the entire washing stage, multiple temperature gears are preset, and each temperature gear corresponds to an operating frequency of the compressor. During actual operation, the temperature in the clothing processing chamber is determined to which temperature gear the temperature in the clothing processing chamber belongs based on the result of comparing the detected temperature in the clothing processing chamber with the temperature gear, and then the compressor is controlled to operate according to the operating frequency of the temperature gear. This control method can enable the temperature in the clothing processing chamber to reach the target temperature before entering the drying stage, which is conducive to shortening the time spent in the drying stage.

[0066] The above-mentioned cleaning operation includes controlling the clothing processing chamber to rotate in a first direction through a motor; the above-mentioned drying operation includes controlling the clothing processing chamber to rotate in a second direction through a motor; wherein, the air volume entering the clothing processing chamber when the clothing processing chamber rotates in the first direction is less than the air volume entering the clothing processing chamber when the clothing processing chamber rotates in the second direction, and the first direction and the second direction are opposite.

[0067] The first direction and the second direction affect the amount of air supplied to the clothing processing chamber, that is, there is an embodiment, the above-mentioned clothing processing equipment also includes a fan, the air duct of the fan is connected to the clothing processing chamber, the fan and the clothing processing chamber are driven to rotate by the same motor; when the clothing processing chamber rotates in the first direction, the air supply of the fan is less than the air supply of the fan when the clothing processing chamber rotates in the second direction, and the first direction and the second direction are opposite.

[0068] Taking the laundry processing chamber of the laundry processing device as an example, the single-motor laundry processing device of the embodiment of the present application includes a motor for driving the drum to rotate and driving the fan to rotate, the output shaft of the motor is connected to the rotating shaft of the drum, the output shaft of the motor is also connected to the rotating shaft of the fan, and the fan is connected to the inner cavity of the drum through an air supply duct for supplying air to the inner cavity of the drum. It can be understood that since the rotation speed of the motor and the rotation speed of the drum are different, there is a certain corresponding relationship between the ratio of the rotation speed of the motor and the rotation speed of the drum according to the specific structure of the laundry processing device. For example, the output shaft of the motor is indirectly connected to the rotating shaft of the drum through structures such as gears and belts, and the gears and belts provide a speed conversion method similar to the gear ratio, for example, 2000 revolutions per minute of the motor corresponds to about 40 revolutions per minute of the drum; similarly, there may be a certain speed conversion relationship between the speed of the fan and the speed of the motor. Since the fan can have a higher speed, according to different specifications of the fan, the speed conversion relationship may also be 1:1, which is not limited here. In addition, during the operation of the laundry processing device, the number of rotations of the drum in the first direction is smaller than the number of rotations in the second direction. For example, the number of rotations in the second direction can be 8:1 or 12:1, etc. Assuming that the first direction is the direction of reverse rotation of the drum and the second direction is the direction of forward rotation of the drum, then in the cleaning stage and the drying stage, the drum rotates forward and reverse alternately, for example, the drum rotates forward 10 times and then reverses 1 time, etc. Among them, the forward rotation of the fan is a normal air supply condition, but the reverse rotation of the fan makes it difficult or impossible to supply air to the drum, so adjusting the rotation direction of the motor can affect the cleaning effect and drying effect of the laundry processing device.

[0069] Taking the clothes processing device of the embodiment of the present application as a heat pump heating device as an example, in the cleaning stage, the motor controls the drum to rotate in the first direction (reverse rotation), so that the air supply of the fan is at a low level, so as to avoid the fan air supply affecting the combination of the cleaning solvent and steam with the clothes, and the heat pump system does not heat; in the drying stage, the motor controls the drum to rotate in the second direction (forward rotation), so that the air supply of the fan is at a high level, and the heat pump system works to heat the air sent into the drum, and the heated air is mixed with the wet and cold air in the drum and then output to enter the circulation process of the heat pump system. In this process, the motor drives the drum to rotate in the reverse direction mainly in the cleaning stage, and drives the drum to rotate forward mainly in the drying stage. It can be understood that although the drum mainly rotates in the reverse direction in the cleaning stage and mainly rotates forward in the drying stage, the motor can drive the drum to rotate forward for a short time in the cleaning stage to shake out the clothes in the drum and promote the combination of steam and clothes. Similarly, in the drying stage, the motor can drive the drum to rotate in the reverse direction for a short time to shake out the clothes in the drum so that the heated air can fully contact with the clothes.

[0070] It can be understood that the clothing processing objects of the clothing processing device in the embodiment of the present application may include multiple types and are not limited to the clothing mentioned above. It can also be, for example, bed sheets, mosquito nets, etc., and can also be other industrial products. No limitation is made here. For the sake of convenience of expression, the following embodiments are explained with the clothing processing object being clothing.

[0071] Reference Figure 3 As shown, in some embodiments, the clothing processing device further includes a steam generator; in the above step S110, controlling the clothing processing chamber to rotate in the first direction by a motor includes:

[0072] Step S111, controlling the laundry processing chamber to rotate in the first direction for a third preset time period and then in the second direction for a fourth preset time period by means of a motor;

[0073] Step S112, starting the steam generator to deliver steam to the clothes processing chamber, and controlling the clothes processing chamber to rotate in the first direction for a fifth preset time period through the motor.

[0074] The cleaning stage is divided into two stages. The first stage is to clean the clothes with a cleaning solvent, and the second stage is to clean with the steam introduced. The cleaning solvent is premixed before the cleaning stage begins, and the premixed cleaning solvent is added to the drum. Then the clothing processing device enters the first stage of the cleaning stage. The motor drives the drum to rotate in the first direction for a third preset time, and then rotates in the second direction for a fourth preset time, which can shake the clothes in the drum so that the premixed cleaning solvent can fully contact the clothes at different positions in the drum. Then enter the second stage. The motor continues to drive the drum to rotate in the first direction, and at the same time, steam is delivered to the drum through the steam generator. In this stage, the motor drives the drum to rotate in the first direction for a fifth preset time, so that the steam can fully contact the clothes at different positions in the drum. Using the cleaning solvent and steam in the above two stages, oil-soluble dirt and water-soluble dirt can be dissolved respectively. Among them, the third preset time and the fifth preset time can be set according to actual needs. For example, the standard cleaning program fixes the third preset time to 10 minutes and the fifth preset time to 5 minutes, or the user can set the values ​​of the third preset time and the fifth preset time by himself, which is not limited here. The third preset time length and the fifth preset time length may be set to be greater than the fourth preset time length.

[0075] In some embodiments, the clothing processing equipment further includes a foam delivery device, and the cleaning operation further includes: turning on the foam delivery device to output cleaning foam to the clothing processing chamber. The clothing processing equipment of the embodiment of the present application converts the cleaning volume into foam through the foam delivery device, and cleans the clothing by combining the foam with the stains, which is different from the traditional water-washed clothing cleaning method and does not require a drainage structure. The specific structure of the foam delivery device is designed according to actual needs. In some embodiments, the clothing processing equipment further includes a premixing chamber, a peristaltic pump and a foam pump. The two inlets of the premixing chamber are respectively connected to the water inlet pipe and the peristaltic pump. A water inlet valve is provided in the water inlet pipe, and the outlet of the premixing chamber is connected to the foam pump; refer to Figure 4 As shown, before controlling the laundry processing chamber to rotate in the first direction by the motor, the control method of the embodiment of the present application further includes:

[0076] Step S101, opening the water inlet valve to let water in, and starting the peristaltic pump to deliver the cleaning solvent;

[0077] Step S102, closing the water inlet valve and the peristaltic pump, leaving the chamber to stand for a sixth preset time to allow the cleaning solvent and water to mix, and controlling the motor to rotate the laundry processing chamber to shake the laundry loose;

[0078] Step S103, turning on the foam pump to output the premixed cleaning solvent to the laundry processing chamber.

[0079] The premixing chamber provides a place for the cleaning solvent and water to mix, so it has two inlets, one of which is connected to the water inlet pipe to let water into the premixing chamber, and the other is connected to the output port of the peristaltic pump. The input port of the peristaltic pump is connected to a container storing the cleaning solvent, and the peristaltic pump draws the cleaning solvent from the container into the premixing chamber. The water inlet pipe is connected to a water outlet such as a faucet, and a water inlet valve is arranged in the water inlet pipe. Controlling the water inlet valve to open allows water to enter the premixing chamber, and controlling the water inlet valve to close stops adding water to the premixing chamber.

[0080] The water inlet valve can be controlled to open and the peristaltic pump can be operated at the same time, or the time when the water inlet valve is opened and the time when the peristaltic pump is operated can be staggered; for example, the water inlet valve is controlled to open for 30 seconds first, so that a certain amount of water is filled at the bottom of the premixing chamber, and then the peristaltic pump is controlled to open for 5 seconds, and then the water inlet valve is controlled to open for 30 seconds, so that the water and the cleaning solvent can be fully mixed. The opening time of the above-mentioned water inlet valve and the opening time of the peristaltic pump can be determined according to actual needs. Different water intakes affect the opening time of the water inlet valve, and different peristaltic pump output powers and the output of the cleaning solvent also affect the opening time of the peristaltic pump. After that, the water inlet valve and the peristaltic pump are closed, and the water and the cleaning solvent are allowed to stand in the premixing chamber for a sixth preset time. The sixth preset time can be 30 seconds or other time, which is not limited here. After the standing is completed, the foam pump connected to the outlet of the premixing chamber is started to output the premixed cleaning solvent. At this time, the premixed cleaning solvent is foamy after being processed by the foam pump to improve the combination effect of the premixed cleaning solvent and the clothes.

[0081] Reference Figure 5 As shown, in some embodiments, during the premixing process, the clothes processing chamber is rotated by a motor to shake out the clothes, including:

[0082] Step S104, controlling the clothes processing chamber to rotate alternately in a first direction and a second direction through a motor.

[0083] Before adding the premixed cleaning solvent to the drum, it is necessary to shake out the clothes in the drum to avoid the clothes from being entangled and difficult to combine with the premixed cleaning solvent. This is often after the user puts the clothes into the drum, so it is necessary to control the rotation of the drum to shake out the clothes. In this embodiment, the motor is controlled to rotate alternately in the first direction and the second direction for a period of time, for example, first rotate 10 times in the second direction, then rotate 3 times in the first direction, then rotate 10 times in the second direction, and then rotate 3 times in the first direction, and so on. The forward and reverse rotation of the drum can effectively shake out the clothes that the user has just put in. The speed of the drum can be determined according to actual needs. For example, if the speed of the fixed motor is 2200 revolutions per minute, the speed of the drum is about 40 revolutions per minute, that is, if 10 revolutions in the second direction + 3 revolutions in the first direction is a forward and reverse cycle, the drum performs about 3 forward and reverse cycles per minute. In addition, the forward and reverse cycles of the drum may not be constant, for example, first slowly reverse forward and reverse, and then gradually accelerate, etc., which is not limited here.

[0084] Reference Figure 6 As shown, in some embodiments, starting the foam delivery device in the above step 103 to output the premixed cleaning solvent to the clothing processing chamber includes:

[0085] Step S1031, turning on the foam delivery device and stopping the rotation of the laundry processing chamber;

[0086] Step S1032, after the foam dispensing device is turned on for a seventh preset time, the clothing processing chamber is controlled by the motor to rotate in the first direction for an eighth preset time, and the foam dispensing device is turned off.

[0087] Taking the foam delivery device including the foam pump as an example, the premixed cleaning solvent is added to the drum through the foam pump, and the motor is controlled to stop rotating, so that the drum stops rotating. After the foam pump is turned on and the drum stops rotating for the seventh preset time, the drum is controlled to rotate in the first direction for the eighth preset time, during which the foam pump remains turned on. In other words, the sum of the opening time of the foam pump is the seventh preset time and the eighth preset time, and the time for the drum to rotate in the first direction is the eighth preset time. The size of the seventh preset time and the eighth preset time can be adjusted accordingly. For example, the total opening time of the foam pump is 1.5 minutes, the first 1 minute is the seventh preset time, at which time the drum is stationary, and the last 0.5 minutes is the eighth preset time, at which time the drum rotates in the first direction. It can be seen from this that when the foam pump is turned on and the drum rotates, the rotation direction of the drum is the first direction, that is, the direction in which the fan air supply is smaller, which is conducive to the premixed cleaning solvent and the clothes to prevent them from being scattered by the wind.

[0088] Reference Figure 7 As shown, in some embodiments, in the above step S310, the compressor is operated and the clothes processing chamber is controlled to rotate in the second direction by the motor, including:

[0089] Step S311, adjusting the operating frequency and drying time of the compressor according to the cleaning load in the laundry processing chamber;

[0090] Step S312: Control the clothes processing chamber to rotate in a second direction through the motor at a preset speed and drying time.

[0091] In the drying stage, the operating frequency and drying time of the compressor are determined according to the amount of clothes in the drum. When there are more clothes in the drum, the operating frequency of the compressor is increased accordingly, and the drying time is increased, which is equivalent to increasing the temperature and time of hot air delivered to the drum; if there are fewer clothes in the drum, the operating frequency of the compressor is reduced accordingly, and the drying time is reduced, which is equivalent to reducing the temperature and time of hot air delivered to the drum. In the drying stage, the rotation direction of the drum is the second direction, and the speed is the preset speed. At this time, the air supply of the fan is large. The preset speed in this embodiment can be the motor speed. Due to the large inertia of the drum, the motor speed is easier to monitor than the drum speed. Control based on the motor speed can be more accurate. For example, in step S312, the motor is controlled to run at a speed of 2700 rpm to drive the drum to rotate, and the actual speed of the drum may be 50 rpm. Of course, the preset speed can also be the drum speed. The drum speed can be monitored through components such as sensors, so that the speed output by the motor is adjusted based on the monitoring results.

[0092] Through the above cleaning stage and drying stage, the processing of the clothes can be completed. In some cases, the clothes processing device can perform multiple processing cycles, each of which includes a cleaning stage and a drying stage.

[0093] Reference Figure 8 As shown, after the drying stage is completed, the control method further includes:

[0094] Step S400, turning off the compressor and controlling the laundry processing chamber to rotate in the second direction at a preset speed for a ninth preset time period.

[0095] When the drying stage is completed, the cooling process begins. During the cooling process, the compressor is turned off and the drum is kept rotating at a certain speed to gradually reduce the temperature inside the drum. After the compressor is turned off, the air in the air duct stops heating, so that the temperature of the air delivered by the fan drops. The fan uses the waste heat of the heat exchanger to deliver air. At the same time, the drum rotates in the second direction. The rotation speed can maintain the rotation speed of the drying stage and stop after the rotation continues for the ninth preset time. It can also slowly reduce the rotation speed from the rotation speed of the drying stage and finally stop after the ninth preset time.

[0096] Through the steps of the above-mentioned embodiments, the clothing processing equipment with synchronous rotation of the drum and the fan is controlled, and after the premixed cleaning solvent is added into the drum, the cleaning stage and the drying stage are started. In the cleaning stage, the drum is driven to rotate in a first direction, and in the drying stage, the drum is driven to rotate in a second direction. When the drum rotates in the first direction, the air supply of the fan is small, which can avoid the fan supplying too much air volume and affecting the cleaning of clothes with the cleaning solvent, and can also avoid the fan supplying too much air volume and affecting the cleaning of clothes with steam, thereby ensuring the cleaning effect of the clothing processing equipment. Moreover, in the drying stage, when the drum rotates in the second direction, the air supply of the fan is large, which can speed up the drying stage and shorten the drying time. Therefore, the control method of the embodiment of the present application has better effect than the method of performing clothing processing by alternating forward and reverse control of the drum of the clothing processing equipment in the related art.

[0097] The control method of the clothing processing device of the present application is described in detail below through a specific example.

[0101] Step S3, the foam pump is turned on for 1.5 minutes, the drum stops rotating for the first 0.5 minutes, and the drum rotates in the opposite direction for the next 1 minute, with the motor speed being 2200 rpm (the drum rotates about 40 rpm);

[0102] Step S4, turn off the foam pump, the drum rotates in the opposite direction, and the motor speed is 2200 rpm (the drum rotates about 40 rpm);

[0103] Step S5, the drum rotates forward for 1 minute, the steam generator is turned on for 3-6 minutes while the drum rotates reversely, the motor speed is 2200 rpm (the drum is about 40 rpm), and the compressor is turned on in advance during this stage for preheating;

[0104] Step S6, entering the drying stage, the drum rotates forward, the motor speed is 2700 rpm (the drum is about 50 rpm), the operating frequency of the compressor varies according to different loads, and the drying time also varies;

[0105] Step S7, enter the cooling stage, turn off the compressor, the drum rotates forward, and the motor speed is 2700 rpm (the drum is about 50 rpm);
