[0050] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0051] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.
[0052] The drying control method for clothing processing equipment provided in this disclosure reduces power consumption without increasing drying time by adjusting the frequency of the compressor and the speed of the fan at various stages of the clothing drying process. This is achieved by reducing the frequency of the compressor in some stages and increasing the speed of the fan in others.
[0053] The drying control method, medium, and equipment of the clothing processing equipment provided in this disclosure will be described by way of example below with reference to the accompanying drawings.
[0054] Figure 1 This is a flowchart illustrating a drying control method for a garment processing device provided in this disclosure. This method is applicable to application scenarios requiring control of the drying process in a garment processing device, which includes a compressor and a fan. In this disclosure, the garment processing device is a device that uses a heat pump system to achieve the drying function, and can be a household appliance with a drying function such as a washing machine, washer-dryer combo, or dryer. This method can be executed by the drying control device of the garment processing device provided in this disclosure, and the uniform drying control device of the garment processing device can be implemented using software and / or hardware. Figure 1 As shown, the drying control method of this garment processing equipment includes the following steps:
[0055] S101. Determine the current operating stage.
[0056] Based on the temperature change trend, the drying process can be divided into a heating stage (i.e., the first stage), a dehumidification stage (i.e., the second stage), a water-binding drying stage (i.e., the third stage), and a cooling stage (i.e., the fourth stage).
[0057] S102. Based on the current operating stage, control the compressor to operate at the corresponding target frequency and control the fan to operate at the corresponding target speed.
[0058] The garment processing equipment includes a heat pump system and a garment processing drum. The heat pump system includes a compressor, a condenser, and an evaporator, which are located inside the duct of the garment processing equipment.
[0059] The refrigerant circulation path in a heat pump system is as follows: The compressor pressurizes and heats the refrigerant, then the high-temperature, high-pressure refrigerant enters the condenser and releases heat. The circulating air in the duct absorbs this heat, becoming dry, hot air. After exiting the condenser, the refrigerant enters the capillary tube, where its pressure and temperature rapidly decrease. It then enters the evaporator, where the low-temperature refrigerant exchanges heat with the humid, hot air in the duct, transforming the loaded humid air into dry, cold air. Water vapor in the clothes condenses into small droplets and is collected in the drip tray. The low-temperature refrigerant then exits the evaporator and re-enters the compressor, becoming high-temperature refrigerant once more. This heat pump system utilizes the refrigerant's operation, in conjunction with the rotation of the clothes-handling drum within the clothes-handling device, to achieve a drying effect. The compressor's operating frequency is positively correlated with the heat input of the heat pump system; the higher the operating frequency, the higher the heat input.
[0060] The specific circulation path of the circulating air is as follows: As the fan rotates, dry, hot air is blown into the clothes processing drum. Upon entering the drum, the dry, hot air comes into contact with the load to be dried, carrying away moisture in the load as water vapor, thus becoming humid hot air. This humid hot air then passes through a filter and enters the evaporator, where it exchanges heat with the evaporator, causing the water vapor to condense and precipitate, achieving dehumidification. The humid hot air then becomes dry, cold air. This dry, cold air enters the condenser, absorbs the heat released by the condenser, and becomes dry, hot air again, re-entering the clothes processing drum to dry the load inside. The fan speed is positively correlated with the circulating air volume; the higher the speed, the greater the air volume and the higher the airflow rate.
[0061] In this step, based on the current operating stage determined in the previous step, the compressor is controlled to operate at the corresponding target frequency, and the fan is controlled to operate at the corresponding target speed. Different current operating stages correspond to different target frequencies and target speeds.
[0062] For example, during the heating phase, in order to quickly raise the temperature inside the garment processing equipment to facilitate the evaporation of moisture in the load, the compressor is controlled to run at a higher frequency. At the same time, in order to ensure that the heat can fully contact the load and prevent excessive heat loss, the fan is controlled to run at a lower speed.
[0063] For example, during the dehumidification stage, the evaporated water is divided into free water between the loads. Theoretically, the heat absorbed by the evaporation of the load water is balanced with the input heat. The compressor is controlled to run at a medium frequency, and the fan is controlled to run at a relatively high speed.
[0064] For example, in the combined water drying stage, most of the evaporated water is combined water that is a combination of load and water. The higher the temperature, the faster the drying. The compressor is controlled to run at a relatively high frequency, and the fan is controlled to run at a relatively low speed.
[0065] For example, during the cooling phase, the compressor is turned off and the fan runs at a higher speed to cool and dissipate heat from the load by increasing the fan airflow, ensuring that the load is not hot to the touch when the user handles it.
[0066] The drying control method for the garment processing equipment disclosed herein adjusts the target frequency of the compressor and the target speed of the fan at each operating stage, so that the compressor operates at different target frequencies at different operating stages, and at the same time controls the fan to operate at different target speeds at different operating stages. This avoids the compressor from running at a high frequency continuously while ensuring drying efficiency, which helps to reduce power consumption.
[0067] In some embodiments, "determining the current operational phase" includes the following steps:
[0068] Based on the activation of the clothes drying function, the current operating stage is determined to be the first stage;
[0069] "Based on the current operating stage, controlling the compressor to operate at the corresponding target frequency and controlling the fan to operate at the corresponding target speed" includes the following steps:
[0070] Based on the first stage, the compressor is controlled to operate at a first frequency, and the fan is controlled to operate at a first speed.
[0071] In this embodiment, when the clothes drying function is first started, it is the initial stage of the drying process (i.e., the first stage). At this time, the compressor has not yet fully started, and the temperature inside the clothes processing drum is low. It is necessary to quickly raise the temperature inside the clothes processing equipment to facilitate the evaporation of moisture in the load. Therefore, compared with other operating stages, the first stage corresponds to a relatively high first frequency and a relatively low first speed, which causes the compressor to generate more heat in the first stage. At the same time, the circulating air volume is small in the first stage, and the residence time of the high-temperature dry air in the clothes processing drum is longer, which allows the high-temperature dry air to fully contact the load and prevents excessive heat loss, thereby quickly raising the temperature inside the clothes processing drum.
[0072] In some embodiments, after "controlling the compressor to operate at a first frequency and controlling the fan to operate at a first speed", the drying control method further includes the following steps:
[0073] Obtain real-time monitoring parameters;
[0074] Among them, real-time monitoring parameters are used to reflect the degree of drying of clothes. These may include, for example, the filter outlet temperature, humidity or conductivity inside the clothes processing equipment drum, as mentioned below. The specific parameters can be set according to the determined dehumidification conditions, combined water drying conditions or cooling conditions (see below for details).
[0075] "Determining the current operational phase" also includes:
[0076] Based on real-time monitoring parameters, the dehumidification conditions are determined, and the current operating stage is identified as the second stage.
[0077] "Based on the current operating stage, control the compressor to operate at the corresponding target frequency, and control the fan to operate at the corresponding target speed," also includes:
[0078] Based on the second stage, the compressor is controlled to operate at a second frequency, and the fan is controlled to operate at a second speed;
[0079] Among them, the second frequency is less than or equal to the first frequency, and the second rotational speed is greater than the first rotational speed.
[0080] In this embodiment, the second stage is the dehumidification stage following the first stage. During this stage, most of the evaporated water is free water between the fabric fibers. Theoretically, the heat absorbed by the evaporation of the load moisture balances the heat input from the heat pump system, resulting in a relatively high and stable temperature inside the garment processing drum. Compared to the first stage, the second frequency in the second stage is less than or equal to the first frequency, ensuring that the heat provided by the compressor is sufficient for moisture evaporation. The second rotational speed is greater than the first rotational speed, increasing the airflow of the circulating air to quickly remove water vapor and improve the drying speed.
[0081] In some embodiments, the garment processing device further includes a filter, and real-time monitoring parameters include the filter inlet temperature; "determining the dehumidification conditions based on real-time monitoring parameters" includes the following steps:
[0082] Based on the filter outlet temperature, determine the first average temperature for each first preset time interval in the current consecutive interval and the second average temperature for each first preset time interval in the previous consecutive interval.
[0083] The dehumidification condition is determined to be met based on the fact that the difference between the first average temperature and the second average temperature is less than or equal to the first temperature threshold.
[0084] Specifically, the filter outlet temperature reflects the temperature inside the garment processing equipment and can be monitored in real time using a filter outlet temperature sensor. The first preset duration is an integer multiple of the target unit time. Each consecutive first preset duration refers to an integer multiple of consecutive target unit times. In this embodiment, consecutive target unit times overlap; for example, the first target unit time and the second target unit time are consecutive target unit times. The first target unit time includes the time from second 1 to second 60, and the second target unit time includes the time from second 2 to second 61. The current consecutive first preset duration refers to the last consecutive first preset duration after the current target unit time is an integer multiple of consecutive target unit times; the previous consecutive first preset duration refers to the last consecutive first preset duration after a target unit time (e.g., the previous target unit time) before the current target unit time is an integer multiple of consecutive target unit times. The first temperature threshold is used to characterize the end of the heating phase. Since the temperature inside the equipment continuously rises during the heating phase, the heating phase is determined to end when the difference between the first average temperature and the second average temperature is less than or equal to the first temperature threshold. The first preset duration and the time difference before and after the continuous target unit time are different, and the first temperature threshold will also be different. The specific value can be determined by testing.
[0085] For example, the first preset duration is 3 minutes, the target unit time is minutes, and the first temperature threshold is 1°C. A filter port temperature sensor is used to collect the average temperature per second: t1, t2…tn. Based on the average temperature per second, the average temperature per minute is calculated.
[0086] tmin-1=(t1+t2+……t60) / 60, tmin-2=(t2+t3+……t61) / 60,……tmin-n=[tn+tn+1+……t(n+59)] / 60;
[0087] Calculate the average temperature every 3 minutes based on the continuous average temperature per minute:
[0088] T3min-1=(tmin-1+tmin-2+tmin-3) / 3, T3min-2=(tmin-2+tmin-3+tmin-4) / 3,...T3min-n=[tmin-n+tmin-(n+1)+tmin-(n+2)] / 3;
[0089] Therefore, the first average temperature T3min-n for each first preset time interval in the current continuous cycle, and the second average temperature T3min-(n-1) for each first preset time interval in the previous continuous cycle are determined. If the difference between T3min-n and T3min-(n-1) is greater than 1℃, the filter inlet temperature continues to be monitored; if the difference between T3min-n and T3min-(n-1) is less than or equal to 1℃, the dehumidification condition is met, the heating stage ends, and the dehumidification stage begins.
[0090] In some embodiments, "determining the current operational phase" further includes the following steps:
[0091] Based on real-time monitoring parameters, the conditions for achieving combined water drying were determined, and the current operating stage was identified as the third stage.
[0092] "Based on the current operating stage, controlling the compressor to operate at the corresponding target frequency and controlling the fan to operate at the corresponding target speed" includes the following steps:
[0093] Based on the third stage, the compressor is controlled to operate at the third frequency, and the fan is controlled to operate at the third speed;
[0094] Among them, the third frequency is less than or equal to the first frequency, and the third rotational speed is greater than or equal to the first rotational speed.
[0095] In this embodiment, the third stage is the bound water drying stage following the second stage. The water evaporated in this stage is divided into bound water between the fabric fibers and water molecules. The higher the temperature inside the garment processing drum, the faster the drying speed. To ensure the drying speed, the third frequency corresponding to the third stage can be set to be equal to the first frequency; however, to reduce power consumption, the third frequency can be set to be lower than the first frequency. Referring to the first stage, the third rotation speed can be set to be higher than the first rotation speed to quickly carry the evaporated water to the condenser, thereby increasing the drying speed. Based on this, in the third stage, the fan speed can be controlled to alternate between being equal to and higher than the first rotation speed, thereby improving the overall drying speed and drying effect.
[0096] In some embodiments, the garment processing equipment further includes a filter screen, and real-time monitoring parameters include the filter screen inlet temperature; "determining the conditions for achieving bound water drying based on real-time monitoring parameters" includes the following steps:
[0097] Based on the filter outlet temperature, determine the third average temperature for each second preset time interval in the current consecutive period and the fourth average temperature for each second preset time interval in the previous consecutive period;
[0098] The conditions for drying bound water are determined based on the fact that the difference between the third and fourth average temperatures is greater than or equal to the second temperature threshold.
[0099] Specifically, the filter outlet temperature reflects the temperature inside the laundry processing equipment and can be monitored in real time using a filter outlet temperature sensor. The second preset duration is an integer multiple of the target unit time. Each consecutive second preset duration refers to an integer multiple of consecutive target unit times. In this embodiment, consecutive target unit times overlap; for example, the first target unit time and the second target unit time are consecutive target unit times. The first target unit time includes the time from second 1 to second 60, and the second target unit time includes the time from second 2 to second 61. The current consecutive second preset duration refers to the last consecutive second preset duration after the current target unit time is an integer multiple of consecutive target unit times; the previous consecutive second preset duration refers to the last consecutive second preset duration after a target unit time (e.g., the previous target unit time) before the current target unit time is an integer multiple of consecutive target unit times. The second temperature threshold is used to characterize the end of the dehumidification stage. Since the temperature inside the drum is stable and does not rise during the dehumidification stage, the dehumidification stage is determined to end when the difference between the third average temperature and the fourth average temperature is greater than or equal to the second temperature threshold. The second preset duration and the time difference before and after the continuous target unit time are different, and the second temperature threshold will also be different. The specific value can be calibrated according to the test.
[0100] For example, the first preset duration is 5 minutes, the target unit time is minutes, and the first temperature threshold is 1°C. A filter port temperature sensor is used to collect the average temperature per second: t1, t2…tn. Based on the average temperature per second, the average temperature per minute is calculated.
[0101] tmin-1=(t1+t2+……t60) / 60, tmin-2=(t2+t3+……t61) / 60,……tmin-n=[tn+tn+1+……t(n+59)] / 60;
[0102] Calculate the average temperature every 5 minutes based on the continuous average temperature per minute:
[0103] T5min-1=(tmin-1+tmin-2+tmin-3+tmin-4+tmin-5) / 5, T5min-2=(tmin-2+tmin-3+tmin-4+tm in-5+tmin-6) / 5,...T5min-n=[tmin-n+tmin-(n+1)+tmin-(n+2)+tmin-(n+3)+tmin-(n+4)] / 5;
[0104] Therefore, the third average temperature T5min-n for every second preset time interval is determined, and the fourth average temperature T5min-(n-1) for every second preset time interval in the previous consecutive period is determined. If the difference between T5min-n and T5min-(n-1) is less than 1℃, the filter inlet temperature continues to be monitored; if the difference between T5min-n and T5min-(n-1) is greater than or equal to 1℃, the conditions for combined water drying are met, the dehumidification stage ends, and the combined water drying stage begins.
[0105] In some embodiments, "determining the current operational phase" further includes the following steps:
[0106] Based on real-time monitoring parameters, the cooling conditions are determined, and the current operating stage is identified as the fourth stage.
[0107] "Based on the current operating stage, controlling the compressor to operate at the corresponding target frequency and controlling the fan to operate at the corresponding target speed" also includes the following steps:
[0108] Based on the fourth stage, the compressor is shut down and the fan is controlled to run at the fourth speed.
[0109] Among them, the fourth rotational speed is greater than or equal to the first rotational speed.
[0110] In this embodiment, the fourth stage is the final stage of the drying process, namely the cooling stage. During this stage, the load has been dried, and no further heat input from the heat pump system is needed. The compressor is shut down, and only the fan needs to rotate to dissipate heat from the load. To quickly cool the clothes, a fourth rotation speed can be set greater than or equal to the first rotation speed. For example, the fourth rotation speed can be the maximum rotation speed of the fan. Thus, by controlling the fan to operate at a relatively high speed, the clothes can be cooled quickly, shortening the overall drying time.
[0111] In some embodiments, the real-time monitoring parameters include the humidity or conductivity inside the garment processing equipment drum; "determining the cooling conditions based on real-time monitoring parameters" includes the following steps:
[0112] Cooling conditions are determined to be met based on humidity levels being less than or equal to a preset humidity threshold; or...
[0113] The cooling condition is determined based on the conductivity being less than or equal to a preset conductivity threshold.
[0114] Specifically, as the clothes become drier, the humidity or conductivity inside the drum continuously decreases. Therefore, whether the clothes are dried can be determined based on the humidity or conductivity inside the drum. If the humidity is less than or equal to a preset humidity threshold, the clothes are determined to be dried; if the humidity is greater than the preset humidity threshold, the clothes are determined to be undried. Similarly, if the conductivity is less than or equal to a preset conductivity threshold, the clothes are determined to be dried; if the conductivity is greater than the preset conductivity threshold, the clothes are determined to be undried. After determining that the clothes are dried, the combined water drying stage ends, and the cooling stage begins.
[0115] For example, such as Figure 2 The diagram shown is a schematic flowchart of another drying control method for a garment processing device provided in this embodiment of the present disclosure. (Refer to...) Figure 2 The drying control method includes the following steps:
[0116] S201. Based on the start of the clothes drying function, control the compressor to run at the first frequency and control the fan to run at the first speed, and obtain real-time monitoring parameters.
[0117] Among them, real-time monitoring parameters are used to reflect the degree of drying of clothes. These may include, for example, the filter outlet temperature, humidity or conductivity inside the clothes processing equipment drum, as mentioned below. The specific parameters can be set according to the determined dehumidification conditions, combined water drying conditions or cooling conditions (see below for details).
[0118] For example, after the user presses the drying program, the clothes drying function is activated, and the clothes drying process begins. In this embodiment of the disclosure, the clothes drying process can be divided into four stages, specifically including a heating stage, a dehumidification stage, a bound water drying stage, and a cooling stage. The dehumidification stage can also be called the free water drying stage, where free water refers to water between fabric particles, and bound water refers to water bound to water molecules in the fabric. In the heating stage, the temperature inside the drum of the clothes processing equipment rises rapidly to meet the evaporation conditions of the free water between fabric particles. In the dehumidification stage, the heat required for the evaporation of free water is continuously provided to complete the drying of free water. In the bound water drying stage, the heat required for the evaporation of bound water is continuously provided to complete the drying of bound water. In the cooling stage, the temperature inside the drum is lowered to cool the clothes. In S201, after the clothes drying function is activated, the heating stage begins. The compressor is controlled to run at a first frequency to raise the temperature inside the drum, and the fan is controlled to run at a first speed to disperse the heat inside the drum, resulting in a uniform temperature increase inside the drum. To rapidly increase the temperature inside the drum, a relatively high first frequency and a relatively low first rotational speed are used. The first frequency is used to quickly increase the heat inside the drum, while the first rotational speed ensures sufficient heat exchange with the clothing while preventing excessive heat loss. Therefore, by controlling the compressor to operate at the first frequency and the fan to operate at the first rotational speed, the temperature inside the drum is rapidly increased. In one embodiment, the first frequency can be the frequency at which the compressor operates at full load while ensuring its safety, and the first rotational speed can be the starting speed of the fan.
[0119] In addition, for clothing processing equipment with electric auxiliary heating, the electric auxiliary heating can be turned on during the heating stage to further increase the rate at which the temperature inside the drum rises.
[0120] S202. Based on real-time monitoring parameters, if the dehumidification conditions are met, control the compressor to run at the second frequency and control the fan to run at the second speed.
[0121] Specifically, once dehumidification conditions are met based on real-time monitoring parameters, the heating phase ends, and the dehumidification phase begins. During the dehumidification phase, the heat input from the heat pump system should at least cover the heat required for the evaporation of free water between the fabric fibers. Therefore, the second frequency should not exceed the first frequency. To reduce power consumption, the second frequency can be set lower than the first frequency. Additionally, the second rotation speed can be set higher than the first rotation speed, thereby quickly carrying the evaporated moisture to the condenser and increasing the drying speed.
[0122] S203. Based on real-time monitoring parameters, determine that the conditions for drying the combined water have been met, control the compressor to run at the third frequency, and control the fan to run at the third speed.
[0123] The second and third frequencies are both less than or equal to the first frequency, and at least one of them is less than the first frequency.
[0124] Specifically, based on real-time monitoring parameters, once the conditions for combined water drying are met, the dehumidification stage ends, and the combined water drying stage begins. During the combined water drying stage, the higher the temperature inside the drum, the faster the clothes dry. Therefore, to ensure drying speed, the third frequency can be set equal to the first frequency; while to reduce power consumption, the third frequency can be set lower than the first frequency. Similarly, similar to the heating stage, the third rotation speed can be set equal to the first rotation speed to ensure a rapid increase in drum temperature. Alternatively, referring to the dehumidification stage, the third rotation speed can be set higher than the first rotation speed to quickly carry the evaporated moisture to the condenser, increasing the drying speed. Based on this, during the combined water drying stage, the fan speed can be controlled to alternate between equal to and higher than the first rotation speed, thereby improving both the overall drying speed and drying effect.
[0125] S204. Based on real-time monitoring parameters, if the cooling conditions are determined, control the compressor to stop and control the fan to run at the fourth speed.
[0126] Among them, the second speed, the third speed and the fourth speed are all greater than or equal to the first speed, and at least one of them is greater than the first speed.
[0127] Specifically, based on real-time monitoring parameters, once cooling conditions are met, the water-drying stage ends, and the cooling stage begins. During the cooling stage, the clothes are already dried and no heat pump system is needed; only the fan needs to dissipate heat. To rapidly cool the clothes, a fourth speed can be set higher than the first speed. For example, the fourth speed can be the fan's maximum speed. Thus, by controlling the fan to operate at a relatively high speed, the clothes can be cooled quickly, shortening the overall drying time.
[0128] The drying control method for a clothing processing device provided in this disclosure, after the clothing drying function is activated, first controls the compressor to operate at a first frequency and the fan to operate at a first speed. Then, based on real-time monitoring parameters, it determines whether dehumidification, water-binding drying, or cooling conditions have been met. Upon meeting these conditions, control operations on the compressor and fan are executed according to the corresponding conditions. Furthermore, under all the above conditions, the compressor frequency is controlled to be less than or equal to the first frequency, and under at least one condition, the compressor frequency is less than the first frequency, thereby reducing power consumption during the clothing drying process. Simultaneously, under all the above conditions, the fan speed is controlled to be greater than or equal to the first speed, and under at least one condition, the fan speed is greater than the first speed. Increasing the fan speed under these conditions can shorten the drying time. Therefore, the technical solution of this disclosure, by adjusting the compressor frequency and fan speed at each stage of the clothing drying process, can reduce power consumption without increasing the drying time.
[0129] In some embodiments, the second frequency is less than the first frequency, the third frequency is less than or equal to the first frequency, the fourth rotational speed is greater than the second rotational speed, the second rotational speed is greater than the third rotational speed, and the third rotational speed is greater than or equal to the first rotational speed.
[0130] Specifically, Figure 3 This diagram illustrates the temperature changes at each stage of the clothes drying process. (Reference) Figure 3 During the heating phase, the temperature inside the drum rises rapidly, quickly reaching the temperature at which the moisture inside evaporates. During the dehumidification phase, the temperature inside the drum remains relatively stable, as the heat absorbed by the evaporation of moisture from the clothes, the heat lost, and the heat input from the heat pump system reach equilibrium. During the combined drying phase, the temperature inside the drum continues to rise. During the cooling phase, the temperature inside the drum drops rapidly. To adapt to the temperature changes at each stage of the clothes drying process, the compressor is controlled to operate at a first frequency and the fan at a first speed during the heating phase; the compressor is controlled to operate at a second frequency and the fan at a second speed during the dehumidification phase; the compressor is controlled to operate at a third frequency and the fan at a third speed during the combined drying phase; and the compressor is stopped during the cooling phase, and the fan is controlled to operate at a fourth speed. The second frequency is lower than the first frequency, the third frequency is lower than or equal to the first frequency, the fourth speed is higher than the second speed, the second speed is higher than the third speed, and the third speed is higher than or equal to the first speed. In the above frequency and speed settings, setting the first frequency to the maximum and the first speed to the minimum ensures the fastest temperature rise inside the drum during the heating phase. Setting the second frequency to be lower than the first frequency and the second speed to be higher than the first speed ensures sufficient heat for moisture evaporation during the dehumidification phase while reducing power consumption. Setting the third frequency to be less than or equal to the first frequency and the third speed to be greater than or equal to the first speed and less than the second speed ensures the temperature inside the drum continues to rise to evaporate the bound water in the fabric. Considering that the amount of bound water in this stage is much smaller than the amount of free water in the dehumidification phase, setting the third speed to be lower than the second speed ensures that the evaporated water is quickly carried to the condenser and reduces heat loss, thus increasing the drying speed. Setting the fourth speed to the maximum allows for the fastest possible temperature reduction inside the drum, achieving rapid cooling of the clothes being dried. In this way, by executing the most suitable compressor and fan control operations for each stage of the clothes drying process, both drying time and power consumption can be shortened.
[0131] Based on the above embodiments, in one implementation, the third frequency is greater than the second frequency and less than or equal to the first frequency. This causes the compressor to operate at a relatively high frequency, resulting in a higher temperature inside the drum and thus increasing the drying speed. However, considering that higher temperatures make clothes more prone to shrinkage after drying, in another implementation, the third frequency is less than or equal to the second frequency. This causes the compressor to operate at a relatively low frequency, allowing clothes to be dried at a relatively low temperature, effectively preventing shrinkage after drying. Based on these two implementations, two drying modes can also be provided for the user to choose from: in one drying mode, the third frequency is greater than the second frequency and less than or equal to the first frequency, and in another drying mode, the third frequency is less than or equal to the second frequency. This allows the user to select a suitable drying mode based on the quality and material of the clothes, improving the flexibility of clothes drying control.
[0132] In some embodiments, the drying control method further includes the following steps:
[0133] Based on the current operating phase reaching the preset duration, the compressor is controlled to operate at the target frequency corresponding to the next operating phase, and the fan is controlled to operate at the target speed corresponding to the next operating phase.
[0134] Specifically, a maximum running time (i.e., preset time) is set for each operating stage. When the running time of the current operating stage has reached the corresponding preset time, that is, when the running time of the current operating stage has reached the corresponding maximum running time, and the dehumidification conditions, combined water drying conditions, or cooling conditions are still not met, the compressor is controlled to operate at the target frequency corresponding to the next operating stage, and the fan is controlled to operate at the target speed corresponding to the next operating stage.
[0135] For example, the current operating stage is the first stage (i.e. the heating stage). When the running time of the first stage reaches the corresponding maximum running time, the dehumidification conditions are still not met. The compressor is controlled to run at the target frequency (i.e. the second frequency) corresponding to the second stage, and the fan is controlled to run at the target speed (second speed) corresponding to the second stage.
[0136] For example, the current operating stage is the second stage (i.e., the dehumidification stage). When the operating time of the second stage reaches the corresponding maximum operating time, the combined water drying conditions are still not met. The compressor is controlled to operate at the target frequency (i.e., the third frequency) corresponding to the third stage, and the fan is controlled to operate at the target speed (i.e., the third speed) corresponding to the third stage.
[0137] For example, the current operating stage is the third stage (i.e., the combined water drying stage). When the running time of the third stage reaches the corresponding maximum running time, the dehumidification conditions are still not met. The compressor is controlled to run at the target frequency (i.e., the fourth frequency) corresponding to the fourth stage, and the fan is controlled to run at the target speed (i.e., the fourth speed) corresponding to the fourth stage.
[0138] In other words, based on the fact that the compressor cannot operate at the same frequency for a preset time to meet the dehumidification, water drying, or cooling conditions, the corresponding control operations on the compressor and fan are performed.
[0139] In actual drying processes, situations may arise where real-time monitoring parameters fail to determine whether dehumidification, water-binding drying, or cooling conditions have been met, leading to malfunctions in the drying program. Therefore, a maximum runtime (preset duration) is set for each operating stage. If the conditions for proceeding to the next stage are not met when the current stage's runtime reaches the preset duration, the program automatically proceeds to the next stage and executes the control operations for the compressor and fan, ensuring the normal operation of the drying program. The preset duration may vary depending on the operating stage.
[0140] For example, during the dehumidification stage, when the compressor runs at the second frequency for a preset time, if it is determined based on the filter outlet temperature that the combined water drying conditions have not been met, then control operations on the compressor and fan under the combined water drying conditions are performed, that is, the compressor is controlled to run at the third frequency and the fan is controlled to run at the third speed.
