[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 combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

Therefore, the various sequences in the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0046] In the description of the present application, one or more is meant to be one or more, more than two is meant to be two or more, greater than, less than, more than, etc. are understood to not include the number, above, below, etc. are understood to include the number. If it is described as first, second, etc., it is only used to distinguish the technical features for the purpose, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0047] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequence or technical meaning. The "connection" and "coupling" in the present application include direct and indirect connection (coupling) unless otherwise specified.

[0048] Based on this, the present application provides a control method and control device of a laundry treatment device and a laundry treatment device. The compressor is started to preheat before the end of the cleaning stage, the temperature in the laundry treatment cavity is increased, the drying time of the drying stage is reduced, and the drying efficiency is improved.

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

[0050] Reference Figure 1 As shown, an embodiment of the present application provides a control method for a clothes processing device, wherein the clothes processing device includes a compressor and a clothes processing chamber, and the clothes processing chamber has 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 a 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, and controlling the clothes processing device to perform a drying operation.

[0054] The laundry treatment device of the present invention is configured to clean and dry laundry within a laundry treatment chamber. The laundry treatment chamber lacks a water inlet and drainage channel. Unlike conventional washing and drying devices, the laundry treatment device of the present invention cleans the laundry within the laundry treatment chamber by introducing foam, for example, and then performs a drying operation to dry the laundry. The cleaning phase is referred to as the cleaning phase, and the drying phase is referred to as the drying phase. The present invention activates a drying component to preheat the laundry treatment chamber before the cleaning phase ends, raising the temperature within the laundry treatment chamber in advance. This allows the temperature within the laundry treatment chamber to be quickly raised to the desired level upon entering the drying phase, improving drying efficiency and shortening drying time, thereby enhancing the user experience. The drying component is configured to increase the temperature within the laundry treatment chamber, remove moisture from the chamber, and achieve laundry drying. The specific configuration of the drying component is determined by the drying method employed by the laundry treatment device. For example, the drying component may be a heat pump system, which uses a compressor to drive a coolant to output heat, thereby heating the air entering the laundry treatment chamber. Alternatively, the drying component may be an electric heating system, etc. Examples are not provided 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 duration and the second preset time duration can be set according to actual conditions. The first preset time duration represents the cumulative running time of the cleaning operation. After the first preset time duration is reached, the drying component is started. After the drying component runs for the second preset time duration, the clothes processing device is controlled to enter the drying stage. Therefore, in some cases, the total duration of the first preset time duration and the second preset time duration can be considered to be the duration of the cleaning stage. Of course, the total duration of the first preset time duration and the second preset time duration can also be greater than the duration of the cleaning stage. In this way, after the cleaning stage ends, the drying component continues to operate 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 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 the cleaning operation;

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

[0060] The cumulative running time of the cleaning operation is recorded from the start of the cleaning operation. The clothing processing device is set to start the compressor and preheat in advance when the cumulative running time is greater than or equal to the preset first time. In addition, the clothing 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 clothing processing chamber, and then determine when to start the compressor for preheating according to the required cleaning time. The clothing processing device determines the remaining cleaning time based on the cumulative 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 cumulative running time), the compressor can be started for preheating, that is, a certain time is reserved for raising the temperature of the clothing 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. Therefore, reasonably setting the preset time threshold can stabilize the preheating time of the compressor.

[0061] For example, the control method described above determines when to start the compressor based on the remaining cleaning time. For example, if the preset time threshold is 1 minute, the compressor will start one minute before the end of the cleaning phase. Since the remaining cleaning time is basically fixed to the time threshold and the compressor specifications are also fixed, when preheating the compressor in advance, the compressor's operating frequency can be a fixed value, and it will run at a constant operating frequency within the 1 minute remaining cleaning time.

[0062] Additionally, during the preheating process, you can:

[0063] Start the compressor at a preset initial operating frequency and increase 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 cleaning 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. 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, a temperature sensor monitors the temperature inside the laundry processing chamber and adjusts the compressor's operating frequency accordingly. For example, during the entire washing phase, multiple temperature settings are preset, each corresponding to a compressor operating frequency. During actual operation, the detected temperature inside the laundry processing chamber is compared with the temperature settings to determine which temperature setting the chamber belongs to. The compressor is then controlled based on the operating frequency of that temperature setting. This control method ensures that the temperature inside the laundry processing chamber reaches the target temperature before entering the drying phase, which helps shorten the drying phase.

[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 in which the above-mentioned clothing processing device also includes a fan, the air duct of the fan is connected to the clothing processing chamber, and 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] With the laundry treatment cavity of the laundry treatment device being a drum as an example, the laundry treatment device of the embodiment of the present application comprises 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, and the output shaft of the motor is also connected to the rotating shaft of the fan, the fan is connected to the inner cavity of the drum through an air supply pipeline for supplying air to the inner cavity of the drum. It can be understood that, since the rotating speed of the motor and the rotating speed of the drum are not the same, the ratio of the rotating speed of the motor to the rotating speed of the drum has a certain corresponding relationship according to the specific structure of the laundry treatment device, for example, the output shaft of the motor is indirectly connected to the rotating shaft of the drum through gears and belts and the like, the gears and belts provide a rotating speed conversion mode similar to gear ratio, for example, 2000 revolutions per minute of the motor corresponds to about 40 revolutions per minute of the drum; similarly, the rotating speed of the fan and the rotating speed of the motor can also have a certain rotating speed conversion relationship, since the fan can have a relatively high rotating speed, the rotating speed conversion relationship can also be 1:1 according to the different specifications of the fan, which is not limited herein. In addition, during the working process of the laundry treatment device, the number of rotations of the drum in the first direction is smaller than the number of rotations of the drum in the second direction, for example, the number of rotations of the drum in the second direction can be 8:1 or 12:1 or the like compared with the number of rotations of the drum in the first direction, 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 reverses alternately, for example, the drum rotates forward for 10 revolutions and reverses for 1 revolution, etc. Among them, the forward rotation of the fan is the normal air supply working condition, but the reverse rotation of the fan is difficult to supply air to the drum or cannot supply air, therefore, adjusting the rotating direction of the motor can affect the cleaning effect and the drying effect of the laundry treatment device.

[0069] With the laundry treatment device of the embodiment of the present application being a heat pump heating device as an example, in the cleaning stage, the drum is controlled to rotate according to the first direction (reverse rotation) by the motor, so that the air supply amount of the fan is at a low level, avoiding the influence of the air supply of the fan on the combination of the cleaning solvent and the steam with the laundry, and at the same time the heat pump system does not heat; in the drying stage, the drum is controlled to rotate according to the second direction (forward rotation) by the motor, so that the air supply amount of the fan is at a high level, and at the same time the heat pump system works, heating the air supplied into the drum, and the mixed air of the heated air and the wet cold air in the drum is output into the circulation process of the heat pump system. In this process, the reverse rotation of the drum driven by the motor mainly occurs in the cleaning stage, and the forward rotation of the drum driven by the motor mainly occurs in the drying stage. It can be understood that, although the drum mainly reverses in the cleaning stage and the drum mainly forwards in the drying stage, the motor can drive the drum to forward for a short time in the cleaning stage to shake the laundry in the drum, so as to promote the combination of the steam and the laundry, and similarly, the motor can drive the drum to reverse for a short time in the drying stage to shake the laundry in the drum, so that the heated air can fully contact the laundry.

[0070] It can be understood that the clothing processing objects of the clothing processing device in the embodiment of the present application can include multiple types and are not limited to the clothing mentioned above. They 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, the following embodiments are all described with clothing as the clothing processing object.

[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 the motor includes:

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

[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 phase is divided into two stages: the first stage uses a cleaning solvent to clean the clothes, and the second stage uses steam to clean the clothes. The cleaning solvent is premixed before the cleaning phase begins and added to the drum. The laundry processing device then enters the first stage of the cleaning phase. The motor drives the drum to rotate in the first direction for a third preset time, and then in the second direction for a fourth preset time. This loosens the clothes in the drum and allows the premixed cleaning solvent to fully contact the clothes at different locations within the drum. The second stage then begins. The motor continues to drive the drum in the first direction while steam is supplied to the drum via a steam generator. During this stage, the motor drives the drum in the first direction for a fifth preset time, allowing the steam to fully contact the clothes at different locations within the drum. The cleaning solvent and steam used in these two stages can dissolve oil-soluble and water-soluble dirt, respectively. The third and fifth preset times can be set as needed. For example, the standard cleaning program has a fixed third preset time of 10 minutes and a fixed fifth preset time of 5 minutes. Alternatively, the user can set the third and fifth preset times, which are not limited here. The third preset time length and the fifth preset time length may both be set to be greater than the fourth preset time length.

[0075] In some embodiments, the laundry treatment apparatus further comprises a foam dispensing device, and the cleaning operation further comprises: starting the foam dispensing device to output the cleaning foam to the laundry treatment cavity. The laundry treatment apparatus of the embodiments of the present application changes the cleaning volume into foam through the foam dispensing device, and cleans the laundry by combining the foam with the stains, which is different from the traditional cleaning method of washing the laundry, and does not need to be provided with a drainage structure. The specific structure of the foam dispensing device is designed according to actual needs. In some embodiments, the laundry treatment apparatus further comprises a premixing cavity, a peristaltic pump and a foam pump, two inlets of the premixing cavity are respectively connected to a water inlet pipeline and the peristaltic pump, a water inlet valve is arranged in the water inlet pipeline, and an outlet of the premixing cavity is connected to the foam pump; as shown in FIG. 10, before the laundry treatment cavity is controlled to rotate in the first direction by the motor, the control method of the embodiments of the present application further comprises: Figure 4

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

[0077] Step S102: stopping the water inlet valve and the peristaltic pump, standing for a sixth preset time length to make the cleaning solvent and water mix, and rotating the laundry treatment cavity by the motor to shake the laundry;

[0078] Step S103: starting the foam pump to output the premixed cleaning solvent to the laundry treatment cavity.

[0079] The premixing cavity provides a place for the cleaning solvent and water to mix, and therefore has two inlets. One inlet is connected to the water inlet pipeline to let water into the premixing cavity, and the other inlet 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 in the container into the premixing cavity. The water inlet pipeline is connected to a water outlet such as a faucet, and a water inlet valve is arranged in the water inlet pipeline. Controlling the water inlet valve to open can make water enter the premixing cavity, and controlling the water inlet valve to close can stop adding water to the premixing cavity.

[0080] The water inlet valve can be controlled to open and the peristaltic pump can be controlled to work at the same time, or the time when the water inlet valve is controlled to open and the time when the peristaltic pump is controlled to work can be staggered. For example, the water inlet valve is controlled to open for 30 seconds first, so that the bottom of the premixing cavity is filled with a certain amount of water, then the peristaltic pump is controlled to open for 5 seconds, and then the water inlet valve is controlled to open for 30 seconds again, so that the water and the cleaning solvent can be fully mixed. The opening time of the water inlet valve and the opening time of the peristaltic pump can be determined according to actual needs. Different water inlet amounts affect the opening time of the water inlet valve, and different output powers of the peristaltic pump and different output amounts of the cleaning solvent also affect the opening time of the peristaltic pump. Then the water inlet valve and the peristaltic pump are closed, and the water and the cleaning solvent are left to stand in the premixing cavity for a sixth preset time length. The sixth preset time length can be 30 seconds or other time, which is not limited herein. After the standing is completed, the foam pump connected to the outlet of the premixing cavity is started to output the premixed cleaning solvent. At this time, the premixed cleaning solvent is in a foamed state after being processed by the foam pump, so as to improve the combination effect of the premixed cleaning solvent and the laundry.​

[0081] Referring to Figure 5 As shown in some embodiments, in the premixing process, the clothes processing cavity is controlled to rotate by the motor to shake the clothes, including:

[0082] Step S104, the clothes processing cavity is controlled to rotate by the motor in the first direction and the second direction alternately.

[0083] Before the cleaning solvent after premixing is added to the drum, the clothes in the drum need to be shaken first to avoid the clothes being wound together and difficult to combine with the cleaning solvent after premixing. At this time, it is often after the user puts the clothes into the drum, so it is necessary to control the drum to rotate to shake the clothes. In this embodiment, the motor is controlled to rotate in the first direction and the second direction alternately for a period of time, for example, first rotate in the second direction for 10 turns, then rotate in the first direction for 3 turns, then rotate in the second direction for 10 turns, then rotate in the first direction for 3 turns, and so on. The forward and reverse rotation of the drum can effectively shake the clothes just put in by the user. The rotating speed of the drum can be determined according to actual needs, for example, if the rotating speed of the motor is fixed at 2200 rpm, the rotating speed of the drum is about 40 rpm, that is, if 10 turns in the second direction + 3 turns in the first direction is one forward and reverse rotation period, the drum performs about 3 forward and reverse rotation periods per minute. In addition, the forward and reverse rotation period of the drum can not be constant, for example, first slow forward and reverse rotation, then gradually speed up, etc., which is not limited here.

[0084] Referring to Figure 6 As shown in some embodiments, the step 103 of opening the foam dispensing device to output the cleaning solvent after premixing to the clothes processing cavity includes:

[0085] Step S1031, opening the foam dispensing device and stopping the rotation of the clothes processing cavity;

[0086] Step S1032, after the foam dispensing device is opened for a seventh preset time, the clothes processing cavity is controlled to rotate in the first direction for an eighth preset time by the motor, and the foam dispensing device is closed.

[0087] Taking the aforementioned foam dispensing device including a foam pump as an example, the foam pump adds premixed cleaning solvent to the drum. At this point, the motor is controlled to stop rotating, thereby stopping the drum. After the foam pump is turned on and the drum stops rotating for the seventh preset time period, the drum is controlled to rotate in the first direction for the eighth preset time period, during which the foam pump remains on. In other words, the sum of the foam pump on-times is the seventh preset time period and the eighth preset time period, and the drum rotates in the first direction for the eighth preset time period. The seventh and eighth preset time periods can be adjusted accordingly. For example, if the foam pump is turned on for a total of 1.5 minutes, the first minute is the seventh preset time period, during which the drum is stationary, and the last 0.5 minutes is the eighth preset time period, during which the drum rotates in the first direction. Therefore, when the foam pump is turned on and the drum is rotating, the drum rotates in the first direction, which is the direction with the lower airflow from the fan. This facilitates the binding of the premixed cleaning solvent with the clothes and prevents them from being dispersed by the wind.

[0088] Reference Figure 7 As shown, in some embodiments, the operation of the compressor and the control of the laundry processing chamber to rotate in the second direction by the motor in step S310 include:

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

[0090] Step S312: The clothes processing chamber is controlled by the motor to rotate in a second direction at a preset rotation speed and drying time.

[0091] During the drying phase, the compressor's operating frequency and drying time are determined based on the amount of laundry in the drum. When the drum is heavy, the compressor's operating frequency is increased, increasing the drying time, effectively increasing the temperature and duration of the hot air delivered to the drum. When the drum is light, the compressor's operating frequency is decreased, reducing the drying time, effectively decreasing the temperature and duration of the hot air delivered to the drum. During the drying phase, the drum rotates in the second direction and at a preset speed, during which the fan delivers a high air volume. In this embodiment, the preset speed can be the motor speed. Due to the greater inertia of the drum, the motor speed is easier to monitor than the drum speed, making control based on the motor speed more precise. For example, in step S312, the motor is controlled to operate at 2700 rpm to drive the drum, while the actual drum speed may be 50 rpm. Of course, the preset speed can also be the drum speed. Sensors and other components can monitor the drum speed, allowing the motor output speed to be adjusted based on the monitoring results.

[0092] Through the above-mentioned 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] Referring to Figure 8 As shown in FIG. 1, after the drying phase is completed, the control method further includes:

[0094] In step S400, the compressor is turned off and the clothes treatment cavity is controlled to rotate in the second direction at a preset rotating speed for a ninth preset time length.

[0095] When the drying phase is completed, the cooling process is entered, in which the compressor is turned off and the drum is kept rotating at a certain rotating speed, so that the temperature in the drum gradually decreases. After the compressor is turned off, the air in the air heating duct stops being heated, so that the temperature of the air delivered by the fan decreases. The fan delivers air using the residual heat of the heat exchanger, and the drum rotates in the second direction. The rotating speed can be maintained at the rotating speed in the drying phase, and the drum stops rotating after rotating for the ninth preset time length. Alternatively, the rotating speed can be gradually reduced from the rotating speed in the drying phase, and the drum stops rotating after rotating for the ninth preset time length.

[0096] Through the steps of the above embodiments, the clothes treatment device in which the drum and the fan rotate synchronously is controlled. After the premixed cleaning solvent is added into the drum, the cleaning phase and the drying phase are executed. In the cleaning phase, the drum is driven to rotate in the first direction, and in the drying phase, the drum is driven to rotate in the second direction. When the drum rotates in the first direction, the air delivery amount of the fan is small, which can avoid the air delivery amount of the fan being too large to affect the cleaning of the clothes by the cleaning solvent and the cleaning of the clothes by the steam, thereby ensuring the cleaning effect of the clothes treatment device. In the drying phase, when the drum rotates in the second direction, the air delivery amount of the fan is large, which can speed up the drying phase and shorten the drying time. Therefore, the control method of the embodiments has better effects than the method of controlling the clothes treatment device in the related art in which the drum rotates forward and reversely alternately to treat clothes.

[0097] The control method of the clothes treatment device of the present application will be described in detail below through a specific example.

[0098] Referring to Figure 9 As shown in FIG. 1, after the drying phase is completed, the control method further includes:

[0099] In step S1, the clothes treatment program is started.

[0100] In step S2, the water inlet valve is opened for 36 seconds, the peristaltic pump is opened for 4 seconds, the water inlet valve is opened again for 36 seconds, and then the water inlet valve and the peristaltic pump are closed and kept still for 30 seconds to premix the water and the cleaning solvent in the premixing cavity. During this process, the control state bit 10 / 3 of the drum is set to positive and negative rotation operation, and the rotating speed of the motor is set to 2200 revolutions per minute (the rotating speed of the drum is about 40 revolutions per minute) to scatter the clothes.

[0101] Step S3: The foam pump is turned on for 1.5 minutes, with the drum stopping for the first 0.5 minutes and then rotating in the opposite direction for the next minute. The motor speed is 2200 rpm (the drum speed is about 40 rpm).

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

[0103] Step S5: The drum rotates forward for 1 minute, the steam generator is turned on for 3-6 minutes, and the drum rotates in the reverse direction at a motor speed of 2200 rpm (the drum is about 40 rpm). During this stage, the compressor is turned on in advance 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, rotate the drum forward, and the motor speed is 2700 rpm (the drum is about 50 rpm);

[0106] Step S8: stop the machine and the laundry treatment program ends.

[0107] In addition, an embodiment of the present application also provides a control device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the aforementioned control method is implemented.
