Description

Technical Field

[0001] The present invention relates to the technical field of clothes drying, and in particular to a clothes drying method and a clothes drying device, a drying equipment and a storage medium. Background Art

[0002] As people continue to pursue a better quality of life, clothes made of wool and goose down are increasingly appearing in people's wardrobes. However, when caring for such clothes, they often suffer from quality problems due to improper handling methods or means. For example, in the process of drying woolen clothes, due to the complex effects of heat, moisture and mechanical effects in the process of drying clothes with a tumble dryer, wool fabrics are prone to dimensional changes, resulting in felting of wool fabrics during drying. After drying, the fabrics will shrink, become thicker and feel rough, which has a great impact on the style and appearance of wool fabrics.

[0003] When using a tumble dryer or a tumble washer-dryer to dry clothes, in order to ensure that the clothes do not shrink or reduce shrinkage, a rack is placed in the drum and the clothes are placed on the rack for drying. In this drying method, since the clothes are folded, the wind in the drum cannot penetrate the clothes, resulting in only the surface of the clothes being dried while the inside is damp. The user needs to continuously dry the clothes on the reverse side, which is troublesome to operate. At the same time, uneven drying of the clothes can easily cause damage to the clothes, affecting the overall drying effect of the clothes. Summary of the invention

[0054] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] One of the core concepts of the embodiment of the present invention is that, in the existing drying method, since the clothes are folded, the wind in the drum cannot penetrate the clothes, resulting in that only the surface of the clothes is dried, and the inside is wet. The user needs to repeatedly dry the clothes from the opposite side, which is troublesome. At the same time, the clothes are not dried evenly and are easy to be damaged, affecting the overall drying effect of the clothes. Therefore, the embodiment of the present invention provides a clothes drying method: controlling a clothes drying device to dehydrate the clothes, and detecting the moisture content of the clothes after the dehydration is completed; when the moisture content of the clothes is greater than a first moisture content threshold, controlling the clothes drying device to cool the air in the drum; after the cooling is completed, controlling the clothes drying device to dehumidify the drum; when the moisture content of the clothes is less than or equal to the first moisture content threshold, controlling the clothes drying device to heat the air in the drum until the moisture content of the clothes is less than or equal to a second moisture content threshold; when the moisture content of the clothes is less than or equal to the second moisture content threshold, stopping heating the air in the drum until the clothes are dried. By cooling the air in the drum and dehumidifying it after cooling, the water in this state can be easily exchanged with the air, ensuring the dehumidification effect of the wool at this stage. The water in the clothes is difficult to separate from the clothing fibers at low temperatures, so the clothes must be heated during the drying process, while ensuring that the clothes are not damaged by high temperatures. Finally, the clothes drying equipment is controlled to stop heating and the residual heat from drying is used to move the water vapor into the air for moisture and heat exchange, so that the clothes are not allowed to move and will not shrink.

[0056] Reference Figure 1 , shows a flow chart of the steps of a clothes drying method provided by an embodiment of the present invention, and the method may specifically include the following steps:

[0057] Step 101, controlling a clothes drying device to dehydrate clothes, and detecting the moisture content of the clothes after dehydration is completed;

[0058] Moisture content refers to the percentage of water contained in a substance and is used to describe the moisture content in clothing. It is obtained through the humidity sensor in the clothing drying equipment, which can monitor the humidity value of clothing in real time.

[0059] Wool fibers have a certain directional friction effect, so wool clothing is easily shrunk when it is dried, and the heat generated during the drying process and the moisture on the wool will aggravate this phenomenon; according to this principle, during the drying process, the temperature and moisture content of the wool clothing change over time, and the temperature is controlled by the moisture content of the clothing during the drying process to reduce the shrinkage of the clothing. This is not limited in the embodiments of the present invention.

[0060] In this embodiment, when the clothes need to be dried, the washed clothes are dehydrated at a specified rotation speed, and the moisture content of the clothes is detected so that the clothes reach a certain moisture content after dehydration, thereby ensuring the drying time of the clothes.

[0061] Step 102, when the moisture content of the clothes is greater than a first moisture content threshold, controlling the clothes drying device to cool the air in the drum;

[0062] The first moisture content threshold refers to the moisture content range set by the clothes drying device system, which is required to be in the range of 15% to 30%, preferably 20%. The first moisture content threshold is set to the system moisture content range of 15% to 30%, preferably 20%. When the moisture content of the clothes is greater than this moisture content range, the moisture in the clothes is easily exchanged with the air so that the moisture in the clothes can achieve the best moisture exchange effect. The moisture content of the clothes monitored in real time by the humidity sensor in the clothes drying device is fed back to the system main control by the device controller to judge the moisture content.

[0063] At this time, the moisture content on the surface of the clothes is relatively high, and the moisture in the clothes is easily exchanged with the air. In order to ensure that the clothes do not shrink during the drying process, the ambient temperature in the drum is cooled and the fan is turned on to ensure that the high-moisture content clothes and the drum air are effectively exchanged.

[0064] In this embodiment, the humidity sensor in the clothes drying device obtains the moisture content of the clothes in real time. When the detected moisture content of the clothes is greater than the first moisture content threshold, it means that the moisture content in the clothes is high at this time. The clothes drying device is controlled to cool the air in the drum so that the moisture in the clothes is exchanged with the air.

[0065] In some embodiments, step 102 includes the following sub-steps:

[0066] Sub-step S11, controlling the heat pump system of the clothes drying device to start a cooling mode to cool the air in the drum.

[0067] The heat pump system is an energy-efficient heating and cooling technology that absorbs heat from the environment and transfers it to the space or object that needs to be heated, or discharges heat from the space or object that needs to be cooled back to the environment, using components such as evaporators and condensers to achieve heat transfer.

[0068] The temperature of the air in the drum is lowered through the cooling mode, so that the moisture in the air condenses into water droplets, and the moisture in the clothes is quickly removed. Low-temperature cooling can reduce the heat damage to the clothes during the drying process. In this embodiment, the humidity sensor in the clothes drying device obtains the moisture content of the clothes in real time. When the moisture content of the detected clothes is greater than the first moisture content threshold, it means that the moisture content in the clothes is high at this time. By controlling the heat pump system of the clothes drying device to turn on the cooling mode, the air in the drum is cooled and cooled to a certain temperature (ranging from 10°C to 20°C, preferably 15°C) so that the water in the clothes reaches the optimal temperature for exchanging moisture with the air. Lowering the temperature of the air in the drum can accelerate the condensation of moisture in the air into water droplets, thereby quickly removing moisture from the clothes and reducing the drying time, thereby saving energy. At the same time, the fan is turned on to efficiently exchange moisture in the clothes with the air.

[0069] Step 103, after the cooling is finished, controlling the clothes drying device to dehumidify the drum;

[0070] After the refrigeration is completed, the air in the drum is dehumidified to ensure that the air with high humidity content is effectively dehumidified.

[0071] In this embodiment, after the cooling mode ends, the air temperature in the drum is low and the humidity is high. At this time, the moisture in the air has condensed into water droplets, but the clothes and the inner wall of the drum may still be damp. After the cooling ends, the clothes drying device is controlled to dehumidify the drum. The purpose of dehumidification is to reduce the air humidity in the drum to a suitable level to ensure that the clothes are dry. By heating the air in the drum, the moisture evaporates and is discharged from the drum, and the external dry air is introduced to discharge the humid air in the drum.

[0072] In some embodiments, step 103 includes the following sub-steps:

[0073] Sub-step S12, controlling the heat pump system of the clothes drying device to switch from the cooling mode to the dehumidification mode to dehumidify the drum.

[0074] In this embodiment, after the cooling mode ends, the air temperature in the drum is low and the humidity is high. The heat pump system of the clothes drying equipment is controlled to switch from the cooling mode to the dehumidification mode to dehumidify the drum. The data from the humidity sensor is used to determine whether the cooling mode has ended. According to the preset program, the working mode of the heat pump system is automatically switched from the cooling mode to the dehumidification mode. The sensor monitors the temperature and humidity of the air in the drum in real time to ensure the dehumidification effect.

[0075] Step 104: when the moisture content of the clothes is less than or equal to the first moisture content threshold, control the clothes drying device to heat the air in the drum until the moisture content of the clothes is less than or equal to the second moisture content threshold;

[0076] The second moisture content threshold means that during the drying process of clothes, when the moisture content of the clothes drops to a certain value, the control system will stop the heating process to ensure that the clothes reach an appropriate degree of dryness. The purpose of setting the second moisture content threshold is to avoid over-drying, thereby protecting the clothes from heat damage. The second moisture content threshold range is 0% to 10%, preferably 6%. Setting the second moisture content threshold to the system range of 0% to 10%, preferably 6%, can avoid damage to the clothes caused by high temperature during the drying process and prevent over-drying of the clothes.

[0077] The moisture content of the clothes is further obtained. When it is detected that the moisture content of the clothes is less than or equal to a first moisture content threshold (the required range is 15% to 30%, preferably 20%), the cooling and dehumidification of the air in the drum is completed and the next heating stage is entered.

[0078] In this embodiment, when the moisture content of the clothes is less than or equal to the first moisture content threshold, the moisture content on the surface of the woolen clothes is low, and it is difficult for the moisture in the clothes to exchange with the cold air. In order to ensure the moisture drying of the woolen clothes, the drum environment is heated and heated, and the temperature of the air in the drum is monitored in real time to ensure that the temperature is within an appropriate range. The maximum temperature in the drum does not exceed 50°C, preferably 37°C to 42°C. Controlling the heating temperature at 37°C to 42°C can effectively prevent the damage of high-temperature drying to the clothes. Therefore, when the temperature is heated to the highest temperature, it is no longer heated. The appropriate temperature can accelerate the evaporation of moisture in the clothes and make the clothes dry faster. By controlling the temperature within the range of 37°C to 42°C, the drying speed can be ensured to be moderate and avoid being too slow or too fast. It is determined by the sensor data whether the moisture content of the clothes is less than or equal to the second moisture content threshold. If the moisture content is less than or equal to the second moisture content threshold, the controller stops the heater and ends the heating process.

[0079] In some embodiments, step 104 includes the following sub-steps:

[0080] Sub-step S13, controlling the heat pump system of the clothes drying device to switch from the dehumidification mode to the heating mode to heat the air in the drum.

[0081] In this embodiment, the moisture content of the clothes in the drum is monitored in real time by the humidity sensor in the drum. When the moisture content of the clothes is less than or equal to the first moisture content threshold, the heat pump system of the clothes drying device is controlled to switch from the dehumidification mode to the heating mode, and the heating process is started to heat the air in the drum to dry the remaining moisture content of the clothes. When the detected moisture content of the clothes is less than or equal to the second moisture content threshold, the heat pump system of the clothes drying device is controlled to end the heating mode.

[0082] Step 105, when the moisture content of the clothes is less than or equal to a second moisture content threshold, stop heating the air in the drum until the clothes are dried.

[0083] When the moisture content of the clothes is less than or equal to the second moisture content threshold, the moisture content on the surface of the clothes is extremely low, and it is difficult for the moisture in the clothes to be exchanged with the cold air. Therefore, at this stage, the heating method is stopped and the residual temperature is used to dry the last moisture.

[0084] In this embodiment, it is determined by sensor data whether the moisture content of the clothes is less than or equal to the second moisture content threshold value. If it is detected that the moisture content of the clothes is less than or equal to the second moisture content threshold value, the heat pump system of the clothes drying equipment is controlled to stop the heating mode, end the heating process, and monitor the dryness of the clothes in real time to ensure that the clothes are completely dry.

[0085] In some embodiments, the method further comprises:

[0086] When the moisture content of the clothes is greater than a first moisture content threshold, the drum is controlled to operate in a first working mode for a first period of time; the first working mode is that the drum rotates continuously and rotates forward and reversely according to a first preset ratio.

[0087] The first working mode is that the drum continuously rotates in a 1:1 forward and reverse manner so that the clothes run close to the drum wall, that is, the drum continuously rotates one circle forward and one circle reverse, and runs in this mode for a certain period of time.

[0088] The first time length is determined according to the moisture content of the clothes and the setting of the drying program. Usually, the first time length is adjusted according to the type, weight and drying method of the clothes.

[0089] When the moisture content of the clothes is greater than the first moisture content threshold, it indicates that the moisture content of the clothes is relatively high. The drum continues to run in a 1:1 forward and reverse rotation mode to make the clothes close to the drum wall. In order to further ensure that the shrinkage and deformation of the clothes are low, the drying temperature at this stage must be lowered to close the scale structure on the surface of the wool fiber, so that the deformation is smaller when subjected to mechanical force.

[0090] In this embodiment, the moisture content of the clothes is detected in real time by the humidity sensor in the drum. When the moisture content of the clothes is greater than the first moisture content threshold, the first working mode is started, and at the same time, the heat pump system of the clothes drying equipment is controlled to start cooling and refrigeration, so that the drum continues to rotate to ensure that the clothes are evenly distributed in the drum, and the drum is reversed in a 1:1 ratio, which can effectively prevent the clothes from being entangled and ensure that the clothes and air can be effectively dehumidified.

[0091] In some embodiments, the method further comprises:

[0092] After the refrigeration is finished, the drum is controlled to operate for a second period of time in a second working mode; the second working mode is that the drum rotates intermittently and rotates forward and reversely in a second preset ratio, wherein the ratio of the rotation time of the drum to the stop time is within a first preset ratio range.

[0093] The second working mode is that the drum intermittently rotates in a 1:1 forward and reverse manner to make the clothes run close to the drum wall, and the ratio of the rotation and stationary time in each cycle of the intermittent rotation is 3.5% to 7.0%.

[0094] In this embodiment, after the clothes drying device completes refrigeration in the first working mode, the drum is controlled to intermittently rotate in a 1:1 forward and reverse operation mode so that the clothes are close to the drum wall. The ratio of the rotation time of the drum to the static time is 3.5% to 7.0%. The 1:1 forward and reverse rotation can make the clothes evenly flip in the drum to avoid the clothes from being entangled. The clothes run close to the drum wall, so that the clothes can be evenly distributed in the drum, ensuring that the clothes are evenly heated and stressed. In order to achieve the most effective dehumidification, when controlling the rotation of the clothes, the rotation of the clothes should be minimized. Therefore, intermittent rotation is adopted, and the mode of more stops and less rotation is adopted to achieve the best effect in the dehumidification process. At the same time, the heat pump system is controlled to switch from the cooling mode to the dehumidification mode. According to the type of clothes and the drying program, the operation time of the second working mode is set, and the drum is controlled to run for a second time according to the second working mode. This method is mainly for dehumidifying the humid air in the drum. Therefore, when controlling the rotation of the clothes, the rotation of the clothes should be minimized. Therefore, intermittent rotation and the mode of more stops and less rotation can more effectively dehumidify the humid air in the drum.

[0095] In some embodiments, the method further comprises:

[0096] When the moisture content of the clothes is less than or equal to the first moisture content threshold, the drum is controlled to operate in a third operating mode until the moisture content of the clothes is less than or equal to the second moisture content threshold; the third operating mode is that the drum rotates intermittently and unidirectionally, wherein the ratio of the rotation time to the stop time of the drum is within a second preset ratio range.

[0097] The third working mode is that the clothes are rotated in one direction intermittently to ensure that the clothes can be turned over within the specified time. At this time, it can be intermittent rotation against the wall or intermittent turning; the ratio of rotation and stillness time in each cycle of intermittent rotation is less than 1.5%.

[0098] In this embodiment, the humidity sensor of the clothes drying device detects the moisture content of the clothes in real time. When it is detected that the moisture content of the clothes is less than or equal to the first moisture content threshold, the drum is controlled to operate in the third working mode, the drum is controlled to rotate in one direction intermittently, and the heat pump system is controlled to start the heating mode. In this stage, the surface scales of the clothes will open as the temperature rises, and the moisture content of the clothes at this time is also high. In order to ensure that the clothes are not shrunk by the mechanical force generated by the drum, the running state of the clothes must be reduced, but at the same time, the clothes cannot be stopped, which will lead to poor uniformity of drying the clothes. Therefore, the clothes are controlled to be able to turn over within a specified time, and the time ratio of rotation and stillness in each cycle of intermittent rotation is less than 1.5%. Intermittent unidirectional rotation can make the clothes turn over evenly in the drum to avoid the clothes from being entangled. The clothes run close to the drum wall, which can make the clothes evenly distributed in the drum, ensuring that the clothes are evenly heated and stressed. Intermittent turning can ensure that the clothes can be turned over within the specified time, improve the drying efficiency, and ensure that the clothes are dried without being damaged.

[0099] In some embodiments, the method further comprises:

[0100] When the moisture content of the clothes is less than or equal to a second moisture content threshold, the drum is controlled to be stationary until the clothes are dried.

[0101] In this stage, the clothes are operated in a static mode, and the residual heat in the drum is used to dry the last bit of moisture from the clothes.

[0102] In this embodiment, when it is detected that the moisture content of the clothes is less than or equal to the second moisture content threshold, the clothes have been basically dried and only a small amount of water vapor remains in the clothes. To prevent the clothes from shrinking, the drum is operated in a stationary mode and the heat pump system is controlled to stop heating. The clothes are kept stationary in the drum and the residual temperature in the drum is used to move the water vapor into the air for wet heat exchange until the clothes are completely dried.

[0103] Reference Figure 2, shows a logic block diagram of a clothes drying method provided by an embodiment of the present invention. When clothes are dried, the washed clothes need to be dehydrated according to a prescribed procedure. After dehydration, the moisture content of the clothes is obtained in real time and it is determined whether the moisture content of the clothes is greater than a first moisture content threshold. If it is, the heat pump system is controlled to start the cooling mode to cool the air in the drum, and run for a first time in the first working mode. After running for the first time, the heat pump system is controlled to change from the cooling mode to the dehumidification mode and make the drum run for a second time in the second working mode. When the moisture content of the clothes is less than or equal to the first moisture content threshold, the heat pump system of the clothes drying device is controlled to start the heating mode to heat the air in the drum, and the drum is operated in a third working mode. The moisture content of the clothes is obtained in real time. When the moisture content of the clothes is greater than or equal to the second moisture content threshold, the heating process is repeated. When the moisture content of the clothes is less than the second moisture content threshold, the heating is stopped and the drum is controlled to be stationary to dry the clothes for the last time. Finally, the clothes are judged to be dry and the drying is completed.

[0104] It should be noted that, for the sake of simplicity, the method embodiments are described as a series of action combinations, but those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.

[0105] Reference Figure 3 , shows a structural block diagram of a clothes drying device provided by an embodiment of the present invention, which may specifically include the following modules:

[0106] The dehydration control module 301 is used to control the clothes drying device to dehydrate the clothes and detect the moisture content of the clothes after the dehydration is completed;

[0107] This embodiment mainly utilizes the principle that wool clothing shrinks when dried, which is that wool fibers have a certain directional friction effect, which may cause shrinkage. In the process of wool drying, the heat generated and the moisture on the wool will aggravate this phenomenon. According to this principle, in the drying process, the temperature and moisture content of wool clothing change over time. In the drying process, the moisture content of the clothing is used to control the temperature and reduce the shrinkage of the clothing. This embodiment of the present invention is not limited to this.

[0108] In this embodiment, when the clothes need to be dried, the dehydration control module 301 dehydrates the washed clothes at a specified rotation speed and detects the moisture content of the clothes so that the clothes reach a certain moisture content after dehydration, thereby ensuring the drying time of the clothes.

[0109] A cooling control module 302, configured to control the clothes drying device to cool the air in the drum when the moisture content of the clothes is greater than a first moisture content threshold;

[0110] In this embodiment, the humidity sensor in the clothes drying device obtains the moisture content of the clothes in real time. When the detected moisture content of the clothes is greater than the first moisture content threshold, it means that the moisture content in the clothes is relatively high at this time. The refrigeration control module 302 controls the clothes drying device to cool the air in the drum, so that the moisture in the clothes is exchanged with the air.

[0111] A dehumidification control module 303, used to control the clothes drying device to dehumidify the drum after the cooling is completed;

[0112] In this embodiment, after the cooling mode is ended, the dehumidification control module 303 has a lower air temperature and a higher humidity in the drum. At this time, the moisture in the air has condensed into water droplets, but the clothes and the inner wall of the drum may still be damp. After the cooling is ended, the clothes drying device is controlled to dehumidify the drum. The purpose of dehumidification is to reduce the air humidity in the drum to a suitable level to ensure that the clothes are dry. By heating the air in the drum, the moisture evaporates and is discharged from the drum, and external dry air is introduced to discharge the humid air in the drum.

[0113] a heating control module 304, configured to control the clothes drying device to heat the air in the drum until the moisture content of the clothes is less than or equal to a second moisture content threshold when the moisture content of the clothes is less than or equal to the first moisture content threshold;

[0114] The moisture content of the clothes is further obtained. When it is detected that the moisture content of the clothes is less than or equal to a first moisture content threshold (the required range is 15% to 30%, preferably 20%), the cooling and dehumidification of the air in the drum is completed and the next heating stage is entered.

[0115] In this embodiment, when the moisture content of the clothes is less than or equal to the first moisture content threshold, the moisture content on the surface of the woolen clothes is low, and it is difficult for the moisture in the clothes to exchange with the cold air. To ensure the moisture drying of the woolen clothes, the heating control module 304 heats the drum environment and monitors the temperature of the air in the drum in real time to ensure that the temperature is within an appropriate range, and the maximum temperature in the drum does not exceed 50°C, preferably 37°C to 42°C. The sensor data is used to determine whether the moisture content of the clothes is less than or equal to the second moisture content threshold. If the moisture content is less than or equal to the second moisture content threshold, the controller stops the heater and ends the heating process.

[0116] The heating stop module 305 is used to stop heating the air in the drum until the clothes are dried when the moisture content of the clothes is less than or equal to a second moisture content threshold.

[0117] In this embodiment, the heating stop module 305 determines whether the moisture content of the clothes is less than or equal to the second moisture content threshold through sensor data. If it is detected that the moisture content of the clothes is less than or equal to the second moisture content threshold, the heat pump system of the clothes drying equipment is controlled to stop the heating mode, end the heating process, and monitor the dryness of the clothes in real time to ensure that the clothes are completely dry.

[0118] In some embodiments, it also includes:

[0119] The first control module is used to control the drum to operate in a first working mode for a first period of time when the moisture content of the clothes is greater than a first moisture content threshold; the first working mode is that the drum rotates continuously and rotates forward and reversely according to a first preset ratio.

[0120] In this embodiment, the first control module detects the moisture content of the clothes in real time through the humidity sensor in the drum. When the moisture content of the clothes is greater than the first moisture content threshold, the first working mode is started, and at the same time, the heat pump system of the clothes drying equipment is controlled to start cooling and refrigeration, so that the drum continues to rotate to ensure that the clothes are evenly distributed in the drum, and the drum is reversed in a 1:1 ratio, which can effectively prevent the clothes from being entangled and ensure that the clothes and air can be effectively dehumidified.

[0121] In some embodiments, it also includes:

[0122] The second control module is used to control the drum to operate for a second period of time in a second working mode after the refrigeration is completed; the second working mode is that the drum rotates intermittently and rotates forward and reversely in a second preset ratio, wherein the ratio of the rotation time of the drum to the stop time is within the first preset ratio range.

[0123] In this embodiment, after the second control module clothes drying device completes cooling in the first working mode, it controls the drum to intermittently rotate in a 1:1 forward and reverse operation mode so that the clothes are close to the drum wall, and the ratio of the rotation time of the drum to the static time is 3.5% to 7.0%. At the same time, the heat pump system is controlled to switch from the cooling mode to the dehumidification mode, and the operation time of the second working mode is set according to the type of clothes and the drying program, and the drum is controlled to operate for a second time in the second working mode. This method is mainly to dehumidify the humid air in the drum, so when controlling the rotation of the clothes, the rotation of the clothes should be minimized, so intermittent rotation and more stop and less rotation mode can more effectively dehumidify the humid air in the drum.

[0124] In some embodiments, it also includes:

[0125] The third control module is used to control the drum to operate in a third working mode when the moisture content of the clothes is less than or equal to the first moisture content threshold value, until the moisture content of the clothes is less than or equal to the second moisture content threshold value; the third working mode is that the drum rotates intermittently and unidirectionally, and the ratio of the rotation time to the stop time of the drum is within a second preset ratio range.

[0126] In this embodiment, the humidity sensor of the clothes drying device detects the moisture content of the clothes in real time. When it is detected that the moisture content of the clothes is less than or equal to the first moisture content threshold, the third control module controls the drum to operate in the third working mode, controls the drum to rotate intermittently in one direction, and controls the heat pump system to start the heating mode. At this stage, the surface scales of the clothes will open as the temperature rises, and the moisture content of the clothes at this time is also high. In order to ensure that the clothes are not shrunk by the mechanical force generated by the drum, the running state of the clothes must be reduced, but at the same time, the clothes cannot be stopped, which will result in poor uniformity in drying the clothes. Therefore, the clothes are controlled to be able to turn over within the specified time, and the ratio of the rotation and static time in each cycle of intermittent rotation is less than 1.5%, ensuring that the clothes are dried without being damaged.

[0127] In some embodiments, it also includes:

[0128] The fourth control module is used to control the drum to be stationary until the clothes are dried when the moisture content of the clothes is less than or equal to the second moisture content threshold.

[0129] In this embodiment, when it is detected that the moisture content of the clothes is less than or equal to the second moisture content threshold, the clothes have been basically dried and only a small amount of water vapor remains in the clothes. To prevent the clothes from shrinking, the fourth control module enables the drum to operate in a stationary mode and controls the heat pump system to stop heating, so that the clothes remain stationary in the drum and the residual temperature in the drum is used to move the water vapor into the air for wet heat exchange, until the clothes are completely dried and the process is ended.

[0130] In some embodiments, the refrigeration control module 302 includes:

[0131] The cooling on submodule is used to control the heat pump system of the clothes drying device to start the cooling mode so as to cool the air in the drum.

[0132] In this embodiment, the humidity sensor in the clothes drying device obtains the moisture content of the clothes in real time. When the detected moisture content of the clothes is greater than the first moisture content threshold, it means that the moisture content in the clothes is relatively high at this time. The refrigeration turning on submodule controls the heat pump system of the clothes drying device to turn on the refrigeration mode, cools the air in the drum to a certain temperature (in the range of 10°C to 20°C, preferably 15°C), and turns on the fan at the same time to efficiently exchange moisture in the clothes with the air.

[0133] In some embodiments, the dehumidification control module 303 includes:

[0134] The first conversion submodule is used to control the heat pump system of the clothes drying device to switch from the cooling mode to the dehumidification mode to dehumidify the drum.

[0135] In this embodiment, after the cooling mode ends, the first conversion submodule controls the heat pump system of the clothes drying equipment to switch from the cooling mode to the dehumidification mode when the air temperature in the drum is low and the humidity is high to dehumidify the drum. The data from the humidity sensor is used to determine whether the cooling mode has ended. According to a preset program, the working mode of the heat pump system is automatically switched from the cooling mode to the dehumidification mode. The sensor monitors the temperature and humidity of the air in the drum in real time to ensure the dehumidification effect.

[0136] In some embodiments, the heating control module 304 includes:

[0137] The second conversion submodule is used to control the heat pump system of the clothes drying device to switch from the dehumidification mode to the heating mode to heat the air in the drum.

[0138] In this embodiment, the second conversion submodule monitors the moisture content of the clothes in the drum in real time through the humidity sensor in the drum. When the moisture content of the clothes is less than or equal to the first moisture content threshold, the heat pump system of the clothes drying device is controlled to switch from the dehumidification mode to the heating mode, and the heating process is started to heat the air in the drum to dry the remaining moisture content of the clothes. When the detected moisture content of the clothes is less than or equal to the second moisture content threshold, the heat pump system of the clothes drying device is controlled to end the heating mode.
