Description

Technical Field

[0001] This disclosure relates to the field of clothing processing technology, and in particular to a control method, apparatus, storage medium and equipment for clothing processing equipment. Background Technology

[0002] With the development of technology, more and more users are choosing to use clothes cleaning equipment such as dryers and washer-dryer combos to clean their clothes.

[0003] In related technologies, some clothing processing equipment with drying functions may include an evaporator, a condenser, a compressor, and a clothing container. Specifically, the compressor pressurizes and heats the refrigerant, then sends the refrigerant to the condenser to release heat, and then sends the refrigerant to the evaporator to absorb heat energy and quickly lower the evaporator's temperature. Additionally, when the air blown out of the drying airflow passes through the evaporator, it transforms the humid, hot air blown out of the clothing container into dry, cold air, where water vapor inside the clothing condenses into small water droplets. Simultaneously, the dry, cold air is blown towards the condenser to output hot, dry air to the clothing container.

[0004] However, during the drying process of these garment processing devices, dehumidification is often required. This dehumidification process frequently causes the compressor to reduce its frequency or lose heat, thus slowing down the drying speed. Therefore, the existing technological solutions cannot simultaneously ensure drying speed and dehumidification. Summary of the Invention

[0005] To address the aforementioned technical problems, this disclosure provides a control method, apparatus, storage medium, and equipment for garment processing equipment.

[0006] The first aspect of this disclosure provides a method for controlling a garment processing device, comprising:

[0007] Perform the drying process;

[0008] Determine that the garment processing equipment is in the cooling phase of the drying process, and control the fresh air device to operate in at least part of the cooling phase.

[0009] Optionally, determining that the garment processing equipment is in the cooling phase of the drying process includes:

[0010] Based on the load reaching the preset drying level, the clothing processing equipment is determined to be in the cooling stage.

[0011] Optionally, determining that the clothing processing equipment is in the cooling stage based on the load reaching a preset drying level includes:

[0012] Based on the fact that the first detection temperature at the inlet of the garment processing chamber and the second detection temperature at the outlet of the garment processing chamber meet the preset drying conditions, the garment processing equipment is controlled to enter the cooling stage.

[0013] Optionally, determining that the garment processing equipment is in the cooling phase of the drying process includes:

[0014] The drying time determines that the garment processing equipment is in the cooling phase of the drying process.

[0015] Optionally, the fresh air control device operates during at least part of the cooling phase, including:

[0016] The fresh air device is controlled to operate continuously during the cooling phase.

[0017] Optionally, the fresh air control device operates during at least part of the cooling phase, including:

[0018] The fresh air device is controlled to operate in the first stage and / or the second stage of the cooling process;

[0019] The cooling stage includes a first stage and a second stage; in the first stage, the heating component of the clothing processing equipment is turned off, and the compressor of the clothing processing equipment is running; in the second stage, both the heating component and the compressor are turned off.

[0020] Optionally, the method further includes: determining the operating time of the fresh air device based on load parameters.

[0021] Optionally, the drying process includes:

[0022] The working mode of the garment processing equipment is determined to be the standard drying mode, and the drying program corresponding to the standard drying mode is run.

[0023] A second aspect of this disclosure also provides a control device for a garment processing apparatus, the device comprising:

[0024] A control module is used to execute the drying program; determine that the garment handling equipment is in the cooling phase of the drying program, and control the fresh air device to operate in at least part of the cooling phase.

[0025] A third aspect of this disclosure also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the control method for the clothing processing device described in the first aspect.

[0026] A fourth aspect of this disclosure also provides a garment processing apparatus, the garment processing apparatus including a memory and a processor;

[0027] The memory stores executable programs or instructions;

[0028] The processor executes the program or instructions to implement the steps of the control method for the clothing processing equipment described in the first aspect.

[0029] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0030] The present disclosure provides a control method for a garment processing device, which determines that the garment processing device is in the cooling phase of the drying process by executing a drying program, and controls the fresh air device to operate in at least part of the cooling phase.

[0031] Specifically, by controlling the fresh air device to operate at least part of the cooling phase, cooler ambient air can be introduced into the drying duct of the clothing processing equipment to lower the temperature of the air in the drying duct. Simultaneously, since the humidity of the ambient air is relatively lower than that of the air in the drying duct, dehumidification can also be achieved.

[0032] The cooling phase of the drying process inherently requires the temperature in the drying duct and / or the garment processing chamber to begin to decrease and / or continue to decrease. Therefore, controlling the fresh air device to operate at least part of the cooling phase to introduce ambient air with lower temperature and / or lower humidity will not only not affect the drying speed of the garment processing equipment, but will also increase the cooling speed of the cooling phase, thereby shortening the total time required to execute the drying process.

[0033] In this way, the heat in the garment processing equipment is not released before the cooling stage, thus ensuring the drying speed of the garment processing equipment while achieving the dehumidification function. Attached Figure Description

[0043] 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.

[0044] 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.

[0045] Typically, some garment drying devices include an evaporator, condenser, compressor, and garment compartment. Specifically, the compressor pressurizes and heats the refrigerant, then sends it to the condenser to release heat, and finally to the evaporator to absorb heat and rapidly lower its temperature. Additionally, as the air blown out of the drying duct passes through the evaporator, it transforms the humid, hot air from the garment compartment into dry, cool air, causing water vapor inside the garments to condense into small water droplets. Simultaneously, the dry, cool air is blown towards the condenser, supplying hot, dry air to the garment compartment.

[0046] However, during the drying process of these garment processing devices, dehumidification is often required. This dehumidification process frequently causes the compressor to reduce its frequency or lose heat, thus slowing down the drying speed. Therefore, the existing technological solutions cannot simultaneously ensure drying speed and dehumidification.

[0047] Therefore, embodiments of this disclosure provide a control method, apparatus, storage medium, and device for a garment processing equipment. By executing a drying program and determining that the garment processing equipment is in the cooling phase of the drying program, a fresh air device is controlled to operate during at least a portion of this cooling phase. This allows the fresh air device to operate only during at least a portion of the cooling phase to introduce ambient air, preventing the removal of heat from the garment processing equipment before the cooling phase. This ensures that the drying speed of the garment processing equipment is achieved while simultaneously providing dehumidification.

[0048] For example, Figure 1 This is a schematic diagram of a garment processing device provided in an embodiment of this disclosure. See also: Figure 1 The clothing processing device 100 in this embodiment may include at least: a clothing processing chamber 101, an evaporator 102, a condenser 103, a compressor 104, a fan 105, and a fresh air device 106.

[0049] as Figure 1 As shown, a refrigerant circulation channel 109 exists between the compressor 104, condenser 103, and evaporator 102. The refrigerant circulation channel 109 is a channel used to assist the garment handling equipment 100 in completing the circulation of refrigerant (i.e., cooling medium).

[0050] Specifically, after the compressor 104 pressurizes and heats the refrigerant, the compressor 104 can expel the pressurized and heated refrigerant and deliver it to the condenser 103 through the refrigerant circulation channel 109 to quickly release the heat of the refrigerant and at the same time raise the temperature of the condenser 103.

[0051] Then, the refrigerant, having released heat, enters the evaporator 102 along the refrigerant circulation channel 109. In the evaporator 102, the refrigerant absorbs heat energy, thereby lowering the temperature of the evaporator 102. When the refrigerant reaches a certain high temperature and high pressure state, it returns to the compressor 104 along the refrigerant circulation channel 109. This completes one refrigerant cycle in the clothing handling equipment 100.

[0052] as Figure 1 As shown, a drying air duct 110 exists between the garment processing chamber 101, the evaporator 102, the condenser 103, and the fan 105. The drying air duct 110 is a channel used to assist the garment processing equipment 100 in completing the air circulation.

[0053] Specifically, the fan 105 sends air into the clothes processing chamber 101. The air flows in the clothes processing chamber 101 and carries away the moisture in the clothes. Then, the humid and hot air is blown towards the evaporator 102 through the drying air duct 110. Since the refrigerant absorbs heat in the evaporator 102, the temperature of the evaporator 102 is low. When the humid and hot air passes through the evaporator 102, it will have its heat and moisture absorbed and become dry and cold air.

[0054] Then, the dry, cold air is blown through the drying duct 110 to the condenser 103. Since the refrigerant releases heat in the condenser 103 and the temperature of the condenser 103 is relatively high, the dry, cold air becomes dry, hot air. The dry, hot air that has passed through the condenser 103 is then blown through the drying duct 110 to the fan, and finally, through the fan 105 and the drying duct 110, the heated, dry hot air is sent into the garment processing chamber 101. In this way, one airflow cycle in the garment processing equipment 100 is completed.

[0055] In some embodiments, see continue to see Figure 1 The garment processing device 100 may also include a filter 107. Specifically, the filter 107 can be positioned between the air outlet of the garment processing chamber 101 and the evaporator 102. That is, when air exiting the garment processing chamber 101 passes through the drying duct 110, it first passes through the filter 107 before being blown towards the evaporator 102. This filters out lint and other debris in the air, thereby reducing the risk of the drying duct 110 becoming clogged due to airborne debris.

[0056] In some embodiments, the garment processing device 100 may further include a water-cooling assembly, a liquid collection box, and other devices. For example, the water-cooling assembly may be disposed between the filter 107 and the evaporator 102, and cold water may be circulated into the water-cooling assembly, so that the air delivered through the filter 107 can have its temperature reduced when passing through the water-cooling assembly. As another example, the liquid collection box may be used to collect and / or drain water droplets that have separated from the air when the humid air becomes dry air.

[0057] In some embodiments, see Figure 1 The garment processing equipment 100 may also include a heating element 108. The heating element 108 may be a heating element such as a resistance wire.

[0058] Specifically, the heating element 108 can be disposed between the condenser 103 and the fan 105. That is, the dry hot air passing through the condenser 103 can be blown to the heating element 108 through the drying duct 110 for further heating, and then blown to the fan 105 through the drying duct 110. In this way, the temperature of the dry hot air in the drying duct 110 can be further increased.

[0059] In this embodiment, the fresh air device 106 can be a device for introducing ambient air into the drying duct 110. For example, the fresh air device 106 can be an openable damper or an air supply device. Since the ambient temperature is generally lower than the original air temperature in the drying duct 110 during drying, introducing ambient air through the fresh air device 106 can slow down the rate of temperature rise in the drying duct 110 and lower the air temperature in the drying duct 110. This can condense the moisture in the air in the drying duct 110 into water droplets to achieve a dehumidification effect. However, if the fresh air device is operated for a long time, it will cause the temperature in the drying duct 110 to decrease, resulting in a significant decrease in the drying speed.

[0060] Understandably, during the drying process, the air in the drying duct 110 continuously circulates between the garment processing chamber 101, the evaporator 102, the condenser 103, the fan 105, and / or the fresh air device 106. Therefore, the air in the drying duct 110 can serve as circulating air.

[0061] In some embodiments, the garment handling device 100 may also include multiple temperature sensors, such as at least one temperature sensor installed in the refrigerant circulation channel 109 and the drying air duct 110 respectively, to obtain the refrigerant temperature and the circulating air temperature.

[0062] For example, a temperature sensor 1 can be installed between the air outlet of the garment processing chamber 101 and the filter 107 (or between the air outlet of the garment processing chamber 101 and the evaporator 102 if the filter 107 is not present) to detect the air temperature when the circulating air leaves the garment processing chamber 101, i.e., the circulating air temperature at the outlet of the garment processing chamber. A temperature sensor 2 can also be installed between the fan 105 and the air inlet of the garment processing chamber 101 to detect the air temperature when the circulating air enters the garment processing chamber 101, or after the circulating air is heated by the condenser 103 and / or the heating assembly 108, i.e., the circulating air temperature at the inlet of the garment processing chamber.

[0063] For example, a temperature sensor 3 can be installed between the evaporator 102 and the compressor 104 to detect the temperature of the refrigerant when it passes through the compressor inlet, i.e., the compressor inlet refrigerant temperature. A temperature sensor 4 can also be installed between the compressor 104 and the condenser 103 to detect the temperature of the refrigerant when it passes through the compressor outlet, i.e., the compressor outlet refrigerant temperature.

[0064] In addition, temperature sensors can be installed / set in any other possible location, and this disclosure does not limit this.

[0065] In some embodiments, the garment handling device 100 may further include a processor.

[0066] The processor may have functions such as processing, control, and communication, and can be used to execute the steps in the control method of the clothing processing device provided in the embodiments of this disclosure.

[0067] In some embodiments, the garment processing device 100 may further include a communication unit for communicating and interacting with other devices. For example, the communication unit may be a Bluetooth device, an infrared device, a WiFi device, etc. In this case, the user can trigger a remote control or terminal device to output corresponding instructions to the communication unit, and then the communication device can send the instructions to the processor, which will then parse and execute the instructions to control other components or units in the garment processing device. This disclosure does not limit this aspect.

[0068] It is understood that the garment processing equipment may also include other components for realizing any other functions of the garment processing equipment. For example, the garment processing equipment may also include any possible components such as a display device, a power supply device, a reminder device, and a self-test device. This disclosure does not limit this aspect.

[0069] The control method of the clothing processing equipment provided in the embodiments of this disclosure will be described by way of example below with reference to the accompanying drawings.

[0070] For example, Figure 2 This is a flowchart illustrating a control method for a garment processing device provided in this disclosure, which can be executed by a processor in the garment processing device 100.

[0071] See Figure 2 The control method for the garment processing equipment provided in this disclosure embodiment may include:

[0072] Step 210: Perform the drying process.

[0073] In this embodiment, the drying program can refer to a program that can perform standard drying and has a moderate drying time. Specifically, the drying program can dry clothes at a lower temperature and a slower speed, that is, the drying program can dry clothes more gently, which can minimize damage or shrinkage of clothes and reduce wrinkles.

[0074] In this embodiment, the garment processing device can execute the drying program under certain conditions. For example, the garment processing device can execute the drying program only after receiving a drying instruction input by a user or relevant technician; the garment processing device can also execute the drying program only after the washing program and / or spin-drying program has been completed; or the garment processing device can execute the drying program only under any other possible triggering conditions.

[0075] For example, during the drying process, the garment handling equipment can enter different drying stages under corresponding conditions. See, for example... Figure 3 The drying stage may include a rapid heating stage J1, a constant-speed drying stage J2, and a cooling stage J3.

[0076] Generally, see also Figure 3 , Figure 3 The curve L1 shown can refer to the change curve of the refrigerant temperature at the outlet of the compressor, the curve L2 can refer to the change curve of the first detection temperature at the inlet of the clothing processing chamber, and the curve L3 can refer to the change curve of the second detection temperature at the outlet of the clothing processing chamber.

[0077] Specifically, during the rapid heating stage J1, the constant-speed drying stage J2, and the cooling stage J3, the compressor outlet refrigerant temperature, the first detection temperature, the second detection temperature, and the difference between the first and second detection temperatures exhibit corresponding trends. For example, regarding the first detection temperature, it gradually increases during the initial stage of the drying program, such as the rapid heating stage J1, and reaches a relatively stable equilibrium temperature during the later stages of the drying program, such as the constant-speed drying stage J2. As for the second detection temperature, it shows a continuous upward trend throughout the entire process from the start to the end of the drying program.

[0078] Therefore, by observing the changing trends, such as the changing trend of the difference between the first and second detection temperatures, we can understand the degree of drying of the clothes during the drying process, so as to ensure that the clothes can be effectively dried.

[0079] It is understood that the above examples are merely for illustrating the drying stages of the drying process and do not represent that the drying process can only be divided into drying stages in the manner described in the examples above. Furthermore, each drying stage can be further divided into corresponding sub-stages. This disclosure does not limit this aspect.

[0080] It is worth noting that during the drying process, all components in the garment processing equipment that perform the drying function are operational and maintain the corresponding temperature and / or rotation speed for a specified duration. Specifically, the compressor, evaporator, and condenser in the garment processing equipment can operate continuously to circulate the refrigerant, and the compressor in the garment processing equipment can maintain a relatively low operating frequency.

[0081] Step 220: Determine that the garment processing equipment is in the cooling phase of the drying process, and control the fresh air device to operate in at least part of this cooling phase.

[0082] In this embodiment, it can be determined whether the clothing processing device is in the cooling stage in any possible way. For example, it can be determined whether it is in the cooling stage by detecting the temperature at a specific location within the clothing processing device and / or the amount of temperature change over a certain period of time, or by detecting the change in the moisture level and / or weight of the clothing in the clothing processing chamber, or by recording the running time of the drying program. This embodiment of the present disclosure does not limit this.

[0083] In this embodiment, the fresh air device can be the aforementioned fresh air device 106. Furthermore, when the fresh air device is operating, ambient air with a lower temperature from the outside environment can be introduced into the drying duct, thereby appropriately reducing the temperature of the air (i.e., the circulating air) in the drying duct. Simultaneously, if the humidity of the ambient air is low, introducing this ambient air into the drying duct can also improve the dehumidification effect.

[0084] In this embodiment, the cooling phase typically lasts for a period of time to continuously reduce the temperature within the drying duct and / or the clothing processing chamber. Controlling the fresh air device to operate at least part of the cooling phase can mean controlling the fresh air device to operate continuously during the cooling phase to continuously introduce ambient air into the drying duct; it can also mean controlling the fresh air device to operate for a certain period during the cooling phase and shutting it off for another period; or it can mean controlling the fresh air device to operate intermittently during the cooling phase. This disclosure does not limit this aspect.

[0085] It is understandable that, in addition to the cooling phase, the drying process generally includes other heating or temperature-maintaining phases, and the clothes in the garment compartment are mainly dried during these other heating or temperature-maintaining phases. Furthermore, when the fresh air device is controlled to operate, ambient air with lower temperature and / or lower humidity from the external environment is introduced into the drying duct.

[0086] Therefore, if the fresh air device is controlled to introduce ambient air during other heating and / or constant temperature phases, the temperature rise rate in the drying duct and / or the garment processing chamber will slow down or decrease during the heating phase. This will result in a slower drying speed for the garment processing equipment.

[0087] In this embodiment of the disclosure, by executing a drying process, it is determined that the clothing processing equipment is in the cooling phase of the drying process, and the fresh air device is controlled to operate in at least part of the cooling phase.

[0088] In this process, controlling the fresh air device to operate during at least part of the cooling phase can introduce ambient air into the drying duct of the clothing processing equipment. Generally, the temperature of the ambient air is lower, thus achieving the purpose of cooling. At the same time, since the humidity of the ambient air is relatively lower than that of the air in the drying duct, it can also improve the dehumidification capacity.

[0089] The cooling phase of the drying process inherently requires the temperature in the drying duct and / or the garment processing chamber to begin to decrease and / or continue to decrease. Therefore, controlling the fresh air device to operate at least part of the cooling phase to introduce ambient air with lower temperature and / or lower humidity will not only not affect the drying speed of the garment processing equipment, but will also increase the cooling speed of the cooling phase, thereby shortening the total time required to execute the drying process.

[0090] In this way, the heat in the garment processing equipment is not released before the cooling stage, thus ensuring the drying speed of the garment processing equipment while achieving the dehumidification function.

[0091] In addition, during the drying process, the clothes in the garment processing equipment and / or the circulating air in the drying duct may carry a certain odor. Therefore, by introducing ambient air through the fresh air device, the odor in the garment processing equipment can also be removed.

[0092] In one possible implementation, determining that the garment handling equipment is in the cooling phase of the drying process includes:

[0093] Based on the load reaching the preset drying level, it is determined that the clothing processing equipment is in the cooling stage.

[0094] In this embodiment, the load may refer to the clothing in the clothing processing chamber of the clothing processing device.

[0095] In this embodiment, the preset drying degree can be set by relevant technicians or users according to actual needs, and the preset drying degree can be used to characterize whether the load has been dried. This embodiment does not limit this.

[0096] Generally, when the load reaches the preset drying level, it can be determined that the load is basically dried and the temperature of the drying duct and / or clothing processing chamber in the clothing processing equipment can be reduced.

[0097] For example, the preset drying level can generally be determined using information such as the moisture level and / or weight change of the load, the temperature and / or temperature change at a specific location in the garment processing equipment, and the running time of the drying program. This disclosure does not limit this approach.

[0098] It is worth noting that by determining whether the load has reached the preset drying level, it is possible to accurately determine whether the current drying level of the load is high or whether it has basically completed drying. In this way, it is possible to accurately determine whether the garment processing equipment is in the cooling stage, thus facilitating subsequent operations.

[0099] In one possible implementation, determining that the garment processing equipment is in the cooling stage based on the load reaching a preset drying level includes:

[0100] Based on the fact that the first detection temperature at the inlet of the garment processing chamber and the second detection temperature at the outlet of the garment processing chamber meet the preset drying conditions, the garment processing equipment is controlled to enter the cooling stage.

[0101] In this embodiment, the first detection temperature at the inlet of the garment processing chamber can be the temperature of the circulating air in the drying duct entering the garment processing chamber, detected by the temperature sensor 2 located between the fan and the air inlet of the garment processing chamber in the garment processing equipment.

[0102] The second detection temperature at the outlet of the garment processing chamber can be the temperature of the circulating air in the drying duct leaving the garment processing chamber, detected by the temperature sensor 1 located between the air outlet of the garment processing chamber and the evaporator (or filter) in the garment processing equipment.

[0103] In this embodiment, the preset value can be set by relevant technical personnel according to actual needs, and this disclosure does not limit this.

[0104] It is worth noting that the inlet circulating air temperature of the garment processing chamber typically rises over time during the initial stages of the drying process, but reaches a stable equilibrium in the later stages. The outlet circulating air temperature, however, continuously rises from the start to the end of the drying process. Furthermore, the inlet circulating air temperature is generally higher than the outlet circulating air temperature, and the inlet temperature rises at a faster rate. Therefore, by utilizing the correlation between the inlet and outlet circulating air temperatures, the degree of drying of the load during the drying process can be accurately determined.

[0105] In some embodiments, the first detection temperature at the inlet of the garment processing chamber and the second detection temperature at the outlet of the garment processing chamber meet preset drying conditions, specifically including the following steps:

[0106] Step 1: Obtain the upper limit of the temperature difference between the first detection temperature and the second detection temperature, the temperature difference variation value, and the preset dryness judgment temperature difference change amount.

[0107] The upper limit of the temperature difference is used to characterize the maximum temperature difference formed by the first detection temperature and the second detection temperature within the constant-speed drying stage J2.

[0108] Specifically, combined Figure 3 In the early stage of the constant-speed drying stage J2, the temperature difference between the first and second detection temperatures does not rise continuously but fluctuates randomly. To facilitate the determination of the upper limit of the temperature difference, the temperature difference value at any moment within the constant-speed drying stage J2 can be saved and recorded. When a certain temperature difference value is determined to be the largest value in the previous historical records or greater than any temperature difference value in the historical records, and L4 shows a downward trend after that temperature difference value, then the temperature difference value is determined to be the maximum temperature difference value, i.e., the upper limit of the temperature difference (see the highest point of L4 within the constant-speed drying stage J2).

[0109] For example, if the temperature difference between the first and second detection temperatures is 28℃, 29℃, 30℃, 28℃, and 30℃ respectively at a preset time during the constant-speed drying stage J2, and 30℃ is determined to be the largest value in the previous historical records, and L4 shows a decreasing trend when the temperature difference between the first and second detection temperatures is subsequently obtained, then 30℃ is determined to be the upper limit of the temperature difference.

[0110] It is easy to understand that the temperature difference variation value is the real-time changing temperature difference (or temperature range). For example, continuing to combine... Figure 3 When L4 reaches its maximum temperature difference, it will gradually decrease to a certain temperature difference over time. The temperature difference variation value can be any temperature difference within the constant-speed drying stage J2, such as the maximum temperature difference, the minimum temperature difference, or other temperature differences between the maximum and minimum temperature differences, which are not limited here.

[0111] Among them, the preset drying temperature difference change is the main parameter used to determine whether the preset drying conditions are met. Specifically, based on the operation of the drying program, by obtaining the upper limit of the temperature difference, the temperature difference variation value, and the preset drying temperature difference change, it is possible to further determine whether the subsequent preset drying conditions are met, so that the clothes can be dried when it is determined that the preset drying conditions are met.

[0112] Step 2: Based on the difference between the temperature difference variation value and the preset drying temperature difference variation value, determine whether the preset drying conditions are met.

[0113] Conversely, if the temperature difference variation is greater than the difference between the upper limit of the temperature difference and the preset temperature difference variation for drying, then the preset drying conditions are not met, and the clothes are determined to be not dried.

[0114] The preset drying temperature difference variation depends at least on the type of drying program (or the currently running program), the weight of the clothes, and the ambient temperature. The preset drying temperature difference variation is adaptively adjusted according to the type of drying program, the weight of the clothes, and the ambient temperature, thereby ensuring that the clothes can be effectively dried. The selection process of the preset drying temperature difference variation will be illustrated later and will not be repeated here.

[0115] It is easy to understand that, preferably, in the embodiments of this disclosure, other temperature differences after the upper limit of the temperature difference are selected as the temperature difference variation value to ensure the drying effect of the clothes.

[0116] For example, combined Figure 3 L4 has a preset temperature difference change of 3.2℃ and an upper limit of 29.4℃. The difference between the two is 26.2℃. Therefore, the temperature difference change value after the upper limit is compared with 26.2℃ in real time. When a temperature difference value after the upper limit is found to be equal to 26.2℃, it is determined that the preset drying conditions are met, and the clothes are then dried.

[0117] Specifically, the difference between the first detection temperature at the inlet of the garment processing chamber and the second detection temperature at the outlet of the garment processing chamber can be represented by dT. The maximum temperature difference (or upper limit of temperature difference) corresponding to the highest point of L4 in the constant speed drying stage J2 can be represented by dT_max. The preset temperature difference change can be represented by β. In this regard, after decreasing by β relative to dT_max, the corresponding temperature difference change value (i.e., dT) is obtained. This indicates that the preset drying conditions are met, and the garment has been dried. The constant speed drying stage J2 of the drying process ends, and the cooling stage J3 begins.

[0118] It should be noted that although existing garment processing equipment typically uses temperature sensing to determine the degree of drying, such as judging the dryness of clothes after a certain temperature reaches a fixed value, the fixed values ​​set in these technical solutions are relatively absolute and singular. Therefore, during the drying process, they cannot sensitively respond to changes in the ambient temperature and are easily affected by other variables such as the tolerance of the auxiliary heating structure and the accuracy of the negative temperature coefficient thermistors. For example, if the temperature reading of the negative temperature coefficient thermistor installed at the inlet of the garment processing chamber is too high or too low, the temperature will not reach the actual fixed value. As a result, existing garment processing equipment does not accurately judge the degree of drying of clothes, leading to poor drying.

[0119] To address this, the technical solution provided in this disclosure determines that the clothes are dry when the temperature difference variation reaches the difference between the upper limit of the temperature difference and the preset dryness judgment temperature difference change. Compared with the existing technical solution that judges clothes dryness by reaching a fixed temperature, the upper limit of the temperature difference and the preset dryness judgment temperature difference change in this disclosure can be adaptively changed with various variable factors in the drying process. After the preset dryness judgment temperature difference change decreases relative to the upper limit of the temperature difference, the corresponding temperature difference variation value is obtained to judge that the clothes are dry. In this way, the drying detection of clothes is achieved by using dynamic relative values, which is not easily affected by changes in ambient temperature and deviations of components such as the tolerance of auxiliary heating structure. This allows for accurate perception of the degree of drying of clothes and ensures effective drying of clothes.

[0120] As can be seen, the embodiments of this disclosure can determine whether the load has reached the preset drying level in a variety of different ways, and can also set different preset thresholds according to the specific operating parameters of the drying program and / or the current ambient temperature. In this way, the flexibility and applicability of the control method of the clothing processing equipment can be improved.

[0121] In one possible implementation, determining that the garment handling equipment is in the cooling phase of the drying process includes:

[0122] Based on the drying time, it is determined that the garment processing equipment is in the cooling phase of the drying process.

[0123] In this embodiment, the drying time can refer to the duration of the drying process. That is, the drying time is the time from the start of the drying process to the current time.

[0124] Generally, each stage of this drying process has a certain duration; for example, see [link to previous section]. Figure 3 The drying process includes a rapid heating stage J1, a constant-speed drying stage J2, and a cooling stage J3.

[0125] from Figure 3 As can be seen, the rapid heating stage J1 lasts from the start of the drying program to time point p1, the constant-speed drying stage J2 lasts from time point p1 to time point p2, and the cooling stage J3 lasts from time point p2 to time point p4.

[0126] In this case, if the drying time is equal to or greater than the time indicated by time point p2, then it can be determined that the garment processing equipment is in the cooling phase of the drying process. If the drying time is less than the time indicated by time point p2, then it can be determined that the garment processing equipment has not yet entered the cooling phase of the drying process. This disclosure does not limit this aspect.

[0127] It is worth noting that by determining the drying time of the drying program, it is possible to accurately determine whether the garment processing equipment is in the cooling phase of the drying program. This can prevent the heat from being released from the garment processing equipment before the cooling phase, thereby ensuring the drying speed of the garment processing equipment.

[0128] In one possible implementation, controlling the fresh air unit to operate at least partially during the cooling phase includes:

[0129] The fresh air system is controlled to operate continuously during the cooling phase.

[0130] In this embodiment, controlling the fresh air device to operate continuously during the cooling phase means starting from the moment it is determined that the clothing processing equipment is in the cooling phase of the drying program, controlling the operation of the fresh air device until the drying program is completed, and then turning off the fresh air device.

[0131] It is understandable that since the ambient air is continuously introduced through the fresh air device during the cooling phase, this allows for continuous dehumidification using ambient air and also increases the cooling rate during the cooling phase.

[0132] In addition, if the clothing processing chamber in the clothing processing device is equipped with a handle, the handle may become frosty when the drying program reaches the cooling stage. By introducing ambient air through the fresh air device, the moisture on the handle can be quickly dried, so that the user can immediately open the clothing processing chamber through the handle after the drying program is completed. That is, the control method of the clothing processing device provided in this embodiment can also improve the user's experience of using the clothing processing device.

[0133] Alternatively, it may include: controlling the fresh air unit to operate in the first and / or second phases of the cooling process.

[0134] This cooling phase includes at least a first stage and a second stage.

[0135] For example, if the garment processing equipment includes a compressor and a heating element, then in the first stage, the heating element of the garment processing equipment is turned off, and the compressor of the garment processing equipment is operated. In the second stage, both the heating element and the compressor are turned off.

[0136] See also Figure 3 , Figure 3The cooling stage J3 shown includes a first stage J4 and a second stage J5. It is evident that the first stage J4 is the first stage after the constant-speed drying stage J2. In other words, the first stage J4 is the initial cooling stage. In this situation, it can be determined that the load is essentially dried and no further high-heat drying is needed; therefore, cooling can begin. If the fresh air system is turned on for dehumidification, the temperature of the drying duct and the garment processing chamber will decrease slowly. At this time, turning off the heating element and only running the compressor can prevent the garments from shrinking due to a rapid temperature drop after drying.

[0137] The second stage, J5, follows the first stage, J4. After the first stage, J1, has ended, the temperature of the drying duct and the garment processing chamber has decreased somewhat, at which point the compressor can be further shut off. Furthermore, if the fresh air system operates in the second stage, J5, it can quickly lower the temperature of the drying duct and the garment processing chamber, allowing the user to quickly remove the load.

[0138] In addition, during the second phase, while shutting down the heating component and the compressor, the fan in the clothing processing equipment can be turned off or the fan can be kept running until the end of the second phase. This disclosure does not limit this aspect.

[0139] It is understood that, in addition to the first stage and the second stage, the cooling stage may include any other possible target stage. In this case, the fresh air device may operate in the first stage, the second stage, and / or the target stage. This disclosure does not limit the scope of the application.

[0140] In one possible implementation, see [link to relevant documentation]. Figure 4 The method also includes:

[0141] Step 230: Determine the operating time of the fresh air unit based on the load parameters.

[0142] In this embodiment, the load parameter can refer to any possible parameters such as the material of the load, the weight of the load, and the program parameters selected by the user for drying the load.

[0143] Generally, the weight of the load can be input by the user or detected by the weighing device on the clothing processing equipment. The greater the weight of the load, the longer the fresh air system can operate.

[0144] Furthermore, the material of the load can be input by the user or determined by identifying images captured by an image acquisition device installed on the clothing processing equipment. If the load is made of a fragile material, the operating time of the fresh air unit can be set to be longer.

[0145] The program parameters selected by the user for drying the load can be parameters such as drying speed and drying temperature. Generally, the higher the drying speed or the higher the drying temperature, the shorter the running time of the fresh air device can be set. This embodiment does not limit this.

[0146] It should be noted that step 230 can be executed at the same time as step 220, or step 230 can be executed after step 220. This embodiment of the present disclosure does not limit this.

[0147] In this way, the running time can be flexibly adjusted according to the load parameters, which can avoid the problem of over-drying or damaging the load due to excessive running time, and also avoid the problem of the load not being dried due to insufficient running time.

[0148] In one possible implementation, see [link to relevant documentation]. Figure 5 Perform the drying process, including:

[0149] Step 2101: Determine that the working mode of the garment processing equipment is the standard drying mode, and run the drying program corresponding to the standard drying mode.

[0150] In this embodiment, the operating mode of the garment processing device can be adjusted by the user by triggering corresponding operations. For example, the operating mode may include a standard drying mode, a quick drying mode, etc., which can be specifically set by relevant technicians or users.

[0151] Generally, the fast drying mode can refer to a mode that dries quickly, with a short drying time and high drying efficiency. In this mode, the compressor of the garment processing equipment runs at a high frequency and the heating components can continuously heat.

[0152] The standard drying mode can refer to a mode of ordinary drying, with moderate drying time and moderate drying efficiency. In this mode, the compressor of the garment processing equipment operates at a moderate frequency, and the heating components can heat intermittently.

[0153] It is understood that the above examples are merely for illustrating the standard drying mode, the fast drying mode, and the slow drying mode, and do not represent that the various working modes in the embodiments of this disclosure can only be set in the form of the above examples.

[0154] It is worth noting that once the working mode of the garment processing equipment is set to the standard drying mode, the compressor, evaporator, condenser and heating components in the garment processing equipment can be reliably controlled to work continuously at the frequency or power corresponding to the standard drying mode in order to achieve the purpose of drying the clothes.

[0155] In one possible implementation, the method further includes:

[0156] Once the drying process is complete, stop the operation of the fresh air unit.

[0157] It should be noted that once the drying process ends, it indicates that the garment processing equipment has completed the drying work. That is, the evaporator, condenser, compressor, and fan in the garment processing equipment will all stop working. In this situation, the garment processing equipment is already in a shutdown and cooling state. Simultaneously, because the fan has stopped working, the ambient air subsequently introduced by the fresh air unit may not be able to be delivered into the garment processing chamber or flow smoothly in the drying channel. Therefore, controlling the fresh air unit to stop operating not only reduces the energy consumption of the garment processing equipment but also improves the practicality of the control method.

[0158] Based on the above embodiments and the same inventive concept, this disclosure also provides a control device for a garment processing equipment.

[0159] For example, Figure 6 This is a schematic diagram of the structure of a control device for a garment processing equipment provided in an embodiment of this disclosure. See also: Figure 6 The device is used in garment processing equipment and includes:

[0160] The execution control module 301 is used to execute the drying program; determine that the clothing processing equipment is in the cooling stage of the drying program, and control the fresh air device to operate in at least part of the cooling stage.

[0161] It is understood that the control device of the garment processing equipment provided in the embodiments of this disclosure may also include any other possible modules to ensure that the control device of the garment processing equipment can implement the steps of any of the control methods of the garment processing equipment provided in the above embodiments, and has the corresponding beneficial effects, which will not be elaborated here.

Alternatively, when a module is implemented using processing element scheduler code, the processing element can be a general-purpose processor, such as a Central Processing Unit (CPU) or other processor capable of calling program code. Furthermore, these modules can be integrated together as a system-on-a-chip (SOC).
