The laundry treatment device comprises a compressor (Y), a drying air duct, and a heating assembly located in the drying air duct. The control method for a laundry treatment device comprises: turning on a compressor (Y) and a heating assembly and activating air circulation, so as to perform laundry drying; and when it is determined that a drying temperature has reached a threshold temperature, controlling a fresh air apparatus to operate to introduce ambient air into a drying air duct, and maintaining the operation of the heating assembly. In this way, since the temperature of ambient air is relatively low, the speed of the rise of a drying temperature can be decreased, such that over-temperature protection can be prevented from prematurely occurring in a laundry treatment device, thereby enabling the laundry treatment device to maintain high-efficiency drying for a longer period of time. Thus, the drying speed can be effectively increased.

Description

Control methods, devices, storage media and equipment for garment processing equipment

[0001] This disclosure claims priority to Chinese Patent Application No. 202410515797.2, filed on April 26, 2024, entitled "Control Method, Apparatus, Storage Medium and Device for Clothing Processing Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of lock technology, and in particular to a control method, apparatus, storage medium and device for a garment processing equipment. Background Technology

[0003] With the development of technology, various automated home appliances have entered thousands of households, such as dryers, washer-dryer combos and other clothing processing equipment.

[0004] 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, air blown from the clothing container in the drying airflow path is directed towards the evaporator, transforming the humid, hot air from the clothing container into dry, cool air, where water vapor inside the clothing condenses into small water droplets. Simultaneously, the air passing through the condenser in the drying airflow path can output hot, dry air into the clothing container.

[0005] However, in the drying process of these garment processing devices, to achieve rapid drying, the compressor needs to operate at a high frequency or the auxiliary heating function needs to be continuously activated. But this causes the refrigerant and drum outlet temperatures to rise rapidly, triggering temperature protection. Therefore, the existing technologies cannot effectively improve drying speed.

[0022] Optionally, the control method further includes:

[0023] Once the drying temperature has reached its limit, increase the air intake provided by the fresh air device.

[0024] Wherein, the target temperature is greater than the threshold temperature and less than the limit temperature.

[0025] Optionally, controlling the operation of the fresh air device includes:

[0036] (III) Beneficial Effects

[0037] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0038] The present disclosure provides a control method for a clothing processing device, which dries clothes by turning on the compressor, heating element and circulating air; determines that the drying temperature has reached a threshold temperature, controls the operation of the fresh air device to introduce ambient air into the drying air duct of the clothing processing device, and keeps the heating element in the drying air duct running.

[0039] Specifically, when the drying temperature reaches the threshold temperature, ambient air is introduced into the drying duct by controlling the fresh air device to slow down the rate of temperature rise. This prevents the garment processing equipment from triggering its temperature protection mechanism too quickly and causing overheating. Simultaneously, maintaining the operation of the heating components continuously heats the circulating air in the drying duct, preventing the circulating air temperature in the garment processing chamber from becoming too low and affecting the drying effect. In this way, the garment processing equipment can maintain high-efficiency drying for a longer period, effectively improving the drying speed. Attached Figure Description

[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] 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 rapidly reduce the refrigerant's pressure and temperature to absorb heat. Additionally, air blown from the garment compartment in the drying airflow path is directed towards the evaporator, transforming the humid, hot air from the compartment into dry, cool air, where water vapor from the garments condenses into small water droplets. Simultaneously, the air passing through the condenser can then return hot, dry air to the garment compartment.

[0053] However, in the drying process of these garment processing devices, to achieve rapid drying, the compressor needs to operate at a high frequency or the auxiliary heating function needs to be continuously activated. But this causes the refrigerant and drum outlet temperatures to rise rapidly, triggering temperature protection. Therefore, the existing technologies cannot effectively improve drying speed.

[0054] To address this, embodiments of this disclosure provide a control method, apparatus, storage medium, and device for a garment processing equipment. The method involves activating the compressor, heating element, and circulating air to dry garments. Once a threshold temperature is reached, a fresh air device is activated to introduce ambient air into the drying duct of the garment processing equipment, while the heating element remains operational within the duct. Because the ambient air temperature is relatively low, the rate of temperature increase during drying is slowed, preventing the garment processing equipment from triggering overheat protection too quickly. This allows the equipment to maintain high-efficiency drying for an extended period, effectively improving the drying speed.

[0055] For example, FIG1 is a schematic diagram of a clothing processing device provided in an embodiment of the present disclosure. Referring to FIG1, the clothing processing device S in the embodiment of the present disclosure may include at least: clothing processing chamber Q, evaporator Z, condenser L, compressor Y, fan J and fresh air device X.

[0056] As shown in Figure 1, there is a passage a between the compressor Y, condenser L, and evaporator Z. Passage a is a channel used to assist the clothing handling device S in completing the circulation of refrigerant (i.e., cooling medium).

[0057] Specifically, after the compressor Y pressurizes and heats the refrigerant, the compressor Y can expel the pressurized and heated refrigerant and deliver it to the condenser L through channel a to quickly release the heat of the refrigerant and at the same time raise the temperature of the condenser L.

[0058] Then, the refrigerant, having released heat, enters the evaporator Z along channel a. In the evaporator Z, the refrigerant absorbs heat energy, thereby lowering the temperature of the evaporator Z. When the refrigerant reaches a certain high temperature and high pressure, it returns to the compressor Y along channel a. This completes one refrigerant cycle in the clothing processing equipment S.

[0059] As shown in Figure 1, there is a channel b between the garment processing chamber Q, the evaporator Z, the condenser L, the auxiliary heating device F, and the fan J. Channel b is used to assist the garment processing equipment S in completing the air circulation.

[0060] Specifically, fan J sends air into the clothing processing chamber Q. The air flows in the clothing processing chamber Q, carrying away the moisture in the clothes. Then, the humid and hot air is blown through channel b to the evaporator Z. Since the refrigerant absorbs heat in the evaporator Z, the temperature of the evaporator Z is relatively low. When the humid and hot air passes through the evaporator Z, it will have its heat and moisture absorbed and become dry and cold air.

[0061] Then, the dry, cold air is blown towards the condenser L through channel b. Since the refrigerant releases heat in the condenser L and the condenser L has a higher temperature, the dry, cold air becomes dry, hot air. The dry, hot air passing through the condenser L is then blown towards the fan through channel b, and finally, through the fan J and channel b, the heated, dry hot air is sent into the garment processing chamber Q. This completes one airflow cycle in the garment processing equipment S.

[0062] In some embodiments, continuing to refer to Figure 1, the garment processing device S may further include a filter W. Specifically, the filter W may be disposed between the air outlet of the garment processing chamber Q and the evaporator Z. That is, when air exiting the garment processing chamber Q passes through the channel b, it can first pass through the filter W before being blown towards the evaporator Z. This allows for the filtration of lint and other impurities in the air, thereby reducing the risk of the channel b becoming blocked due to impurities in the air.

[0063] In some embodiments, the garment processing device S 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 W and the evaporator Z, and cold water may be circulated into the water-cooling assembly, so that the air delivered through the filter W 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.

[0064] In some embodiments, referring to FIG1, the garment processing device S may further include an auxiliary heating device F. The auxiliary heating device F may be a heating device such as a resistance wire.

[0065] Specifically, the auxiliary heating device F can be installed between the condenser L and the fan J. That is, the dry hot air passing through the condenser L can be blown to the auxiliary heating device F through channel b for further heating, and then blown to the fan J through channel b. In this way, the temperature of the dry hot air in channel b can be further increased.

[0066] In this embodiment, the fresh air device X can be a device for introducing ambient air into the channel b. For example, the fresh air device X can be an openable damper or an air supply device. Since the ambient temperature is generally lower than the original air temperature in the channel b during drying, introducing ambient air through the fresh air device X can slow down the rate of temperature rise in the channel b or even lower the air temperature in the channel b.

[0067] Understandably, during the drying process, the air in channel b continuously circulates between the garment processing chamber Q, evaporator Z, condenser L, fan J, and / or fresh air unit X. Therefore, the air in channel b can serve as circulating air.

[0068] In some embodiments, the garment handling device S may also include multiple temperature sensors, such as at least one temperature sensor installed in channel a and channel b respectively, to obtain the refrigerant temperature and the circulating air temperature.

[0069] For example, a temperature sensor 1 can be installed between the air outlet of the garment processing chamber Q and the filter W (or between the air outlet of the garment processing chamber Q and the evaporator Z if the filter W is not present) to detect the air temperature when the circulating air leaves the garment processing chamber Q, 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 J and the air inlet of the garment processing chamber Q to detect the air temperature when the circulating air enters the garment processing chamber Q, or after the circulating air is heated by the condenser L and / or the auxiliary heating device F, i.e., the circulating air temperature at the inlet of the garment processing chamber.

[0070] For example, a temperature sensor 3 can be installed between the evaporator Z and the compressor Y 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 Y and the condenser L to detect the temperature of the refrigerant when it passes through the compressor outlet, i.e., the compressor outlet refrigerant temperature.

[0071] In addition, temperature sensors can be installed / set in any other possible location, and this application does not limit this.

[0072] In some embodiments, the garment processing device S may further include a processor.

[0073] 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.

[0074] In some embodiments, the garment processing device S 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 the scope of the embodiments.

[0075] 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.

[0076] 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.

[0077] For example, Figure 2 is a schematic flowchart of a control method for a garment processing device provided in this disclosure. This method can be applied to the garment processing device S and is specifically executed by the processor in the garment processing device S.

[0078] Referring to Figure 2, the control method for the garment processing equipment provided in this embodiment may include:

[0079] Step 110: Turn on the compressor, heating element and circulating air to dry the clothes.

[0080] In this embodiment, the compressor may refer to the compressor Y mentioned above, and the heating component may refer to the auxiliary heating device F mentioned above.

[0081] Generally, the garment handling equipment can execute a corresponding drying program under certain conditions, thereby activating the compressor, heating element, and circulating air. For example, the garment handling equipment can execute the drying program only after receiving a drying command input by the user or relevant technician; it can also execute the drying program only after the washing and / or spin-drying programs have been completed; or it can execute the drying program only under any other possible triggering conditions.

[0082] For example, turning on the compressor can mean that the compressor begins to pressurize and heat the refrigerant in the aforementioned channel a; when the compressor is turned on, the refrigerant will also begin to circulate between the compressor, the aforementioned evaporator, and the aforementioned condenser.

[0083] For example, turning on the heating component can mean causing the heating component to start generating heat in order to further heat the dry hot air in the aforementioned channel b.

[0084] For example, turning on the circulating air can refer to turning on the aforementioned fan J and other corresponding components so that the air in the passage b can circulate between the aforementioned clothing processing chamber, the evaporator, the aforementioned condenser, the aforementioned fan and / or the aforementioned fresh air device.

[0085] In this embodiment, the drying program can refer to a program that can perform rapid drying, shorten drying time, and improve drying efficiency.

[0086] It is worth noting that during the drying process, when the compressor, heating element, and circulating air are turned on, all components in the clothing processing equipment that perform the drying function are activated and operate continuously for the corresponding duration. Specifically, the compressor, evaporator, and condenser in the clothing processing equipment can operate continuously to circulate the refrigerant, and the compressor can maintain a relatively high frequency of operation within a reasonable range. Simultaneously, the heating element can be continuously maintained. This allows the temperature of the air in channel b to be increased as quickly as possible, thereby improving the drying efficiency of the clothing processing equipment and shortening the drying time.

[0087] Step 120: Determine that the drying temperature has reached the threshold temperature, control the operation of the fresh air device to introduce ambient air into the drying air duct, and keep the heating component running.

[0088] In this embodiment, the fresh air device can be the aforementioned fresh air device X, and the drying air duct can refer to the aforementioned channel b.

[0089] In this embodiment, the drying temperature can be detected in real time by a temperature sensor installed in the garment processing equipment. Furthermore, the temperature at multiple locations within the garment processing equipment can reflect its operational status. For example, the drying temperature can specifically include at least one of the following: the inlet circulating air temperature of the garment processing chamber, the outlet circulating air temperature of the garment processing chamber, the inlet refrigerant temperature of the compressor, and the outlet refrigerant temperature of the compressor.

[0090] In this embodiment, the threshold temperature is set by relevant technicians according to actual needs. When the drying temperature reaches the threshold temperature, it indicates that the drying temperature of the clothing processing equipment is too high and / or the clothing processing equipment is about to trigger the temperature protection mechanism (i.e., over-temperature protection). At this time, it is necessary to control the fresh air device to introduce ambient air.

[0091] In addition, the threshold temperature is lower than the temperature that can trigger the temperature protection mechanism.

[0092] In this embodiment, the temperature of the ambient air is generally lower than the drying temperature.

[0093] In one possible approach, since the structure of the fresh air device or the method of introducing ambient air may differ, the fresh air device can be controlled in different ways. For example, if the fresh air device is an on / off vent, then controlling the operation of the fresh air device to introduce ambient air into the drying duct of the clothing processing equipment can be done by controlling the corresponding drive component to open the fresh air device. As another example, if the fresh air device is an air supply mechanism similar to a blower, then controlling the operation of the fresh air device to introduce ambient air into the drying duct of the clothing processing equipment can be done by controlling the motor in the fresh air device to operate, driving the impeller in the fresh air device to rotate to blow ambient air into the drying duct. This application does not limit this approach.

[0094] Understandably, as shown in Figure 1, with the structure and working principle of the garment processing equipment S, when the circulating air in the drying duct blows towards the evaporator in the garment processing equipment, the evaporator absorbs the heat from the circulating air. Conversely, when the circulating air blows towards the condenser in the garment processing equipment, the condenser heats the circulating air. Therefore, when controlling the fresh air device to introduce ambient air into the drying duct, the ambient air can be introduced into the space between the evaporator and the condenser, causing the ambient air to blow towards the condenser. This avoids the problem of the evaporator absorbing too much heat, leading to a rapid rise in refrigerant temperature and excessive operating pressure on the compressor.

[0095] It's worth noting that, generally, to protect the garment processing equipment from overheating due to prolonged drying, the equipment monitors the drying temperature. If the temperature is too high (e.g., greater than or equal to a temperature that triggers the temperature protection mechanism), the compressor in the garment processing equipment will reduce its frequency and / or the heating element will shut down to protect the internal components. This results in a slower drying speed.

[0096] It's important to note that at the start of the drying process, the temperature of the circulating air in the drying duct is relatively low, resulting in poor evaporation of moisture from the clothes in the processing chamber. In this situation, turning on the fresh air system will slow down the rate at which the temperature of the circulating air rises. Furthermore, after turning on the fresh air system, the temperature of the circulating air and the refrigerant will not drop instantly; instead, they will continue to rise before starting to decrease. Therefore, when setting the threshold temperature, the issue of the drying temperature continuing to rise after introducing ambient air into the drying duct needs to be considered. In other words, it is necessary to ensure that even when the drying temperature reaches its maximum value after turning on the fresh air system, it will not reach a temperature that would trigger the temperature protection mechanism.

[0097] It's worth noting that when the drying temperature reaches the threshold temperature, it indicates that the garment processing equipment is about to trigger its temperature protection mechanism. At this point, ambient air at a temperature lower than the drying temperature is introduced into the drying duct via a fresh air intake system. This slows down the temperature rise of the condenser in the drying duct. Furthermore, since the humidity of ambient air is generally lower than that of the circulating air, introducing lower humidity ambient air can also enhance the dehumidification capacity of the garment processing equipment.

[0098] Meanwhile, by keeping the heating components running during the operation of the fresh air device, the circulating air in the drying duct can be continuously heated. This prevents the circulating air temperature in the clothing processing chamber of the clothing processing equipment from being too low, which would affect the drying effect.

[0099] In this embodiment of the disclosure, clothes are dried by turning on the compressor, heating element and circulating air; when the drying temperature reaches the threshold temperature, the fresh air device is controlled to introduce ambient air into the drying air duct of the clothes processing equipment, and the heating element in the drying air duct is kept running.

[0100] Specifically, when the drying temperature reaches the threshold temperature, it indicates that the garment processing equipment is about to trigger the corresponding temperature protection mechanism. By controlling the fresh air device to introduce ambient air into the drying duct, the rate at which the drying temperature rises is slowed down. This prevents the garment processing equipment from triggering the temperature protection mechanism too quickly and causing overheating.

[0101] Simultaneously, maintaining the operation of this heating component ensures continuous heating of the circulating air in the drying duct. This prevents the circulating air temperature in the garment processing chamber from becoming too low, which could negatively impact drying efficiency. This allows the garment processing equipment to maintain high-efficiency drying for an extended period, effectively increasing the drying speed.

[0102] In one possible implementation, the control method further includes:

[0103] After drying begins, the compressor operates at the first frequency. Once the preset conditions are met, the frequency is reduced to the second frequency and maintained at this operating frequency until the clothes are dry.

[0104] In this embodiment, the first frequency is greater than the second frequency. Specifically, those skilled in the art can set appropriate frequencies as the first and second frequencies according to actual needs, and this disclosure does not limit this.

[0105] In this embodiment, the preset conditions may refer to the drying temperature exceeding a certain preset temperature, the compressor being turned on for a period of time exceeding a certain preset time, or other conditions. This embodiment does not limit these conditions.

[0106] In addition, determining the dryness of clothes can refer to the state in which clothes are basically dried. Specifically, the drying status of clothes can be judged based on the operation of the drying program or the changes in the drying temperature.

[0107] For example, referring to Figure 3, the drying process of the clothing processing equipment may include multiple different drying stages. For example, the drying stage may include at least a heating stage S1, a constant speed stage S2, and a cooling stage S3. In addition, the curve q1 shown in Figure 3 may refer to the change curve of the circulating air temperature at the inlet of the clothing processing chamber, and the curve q2 may refer to the change curve of the circulating air temperature at the outlet of the clothing processing chamber.

[0108] The heating phase S1 refers to the phase from the moment the compressor is turned on and drying begins until the end of time point d1. The constant-speed phase S2 refers to the phase from the beginning of time point d1 until the end of time point d2. The cooling phase S3 refers to the phase from the beginning of time point d2 until the end of time point d3.

[0109] Under normal circumstances, during the heating stage S1, the compressor operates at a high frequency (i.e., the first frequency) and the heating element is in operation. As can be seen from curves q1 and q2, the temperature of the circulating air rises at a relatively fast rate, which can quickly increase the temperature of the circulating air in the drying duct.

[0110] During the constant speed phase S2, the compressor operates at a lower frequency (i.e., the second frequency). At this time, the heating components can also continue to work. As can be seen from curves q1 and q2, the temperature of the circulating air is still rising, but the rate of temperature rise is relatively slower.

[0111] Additionally, during the cooling phase S3, the heating components are typically turned off, allowing the compressor to run at a lower frequency for a period of time. Afterward, the compressor is turned off, and only the fan remains on to achieve the cooling effect. As can be seen from curves q1 and q2, the temperature of the circulating air drops rapidly, eventually approaching room temperature.

[0112] For example, the dryness of the clothes can be determined based on the difference between the inlet and outlet temperatures of the circulating air in the clothes storage cavity and the changes in that difference.

[0113] Specifically, the difference between the inlet circulating air temperature and the outlet circulating air temperature of the clothing container cavity can be continuously detected, thereby determining the maximum value of the difference.

[0114] Then, it is detected whether the target temperature has decreased after the difference reaches its maximum value. If so, it can be determined that the clothes in the clothes receiving cavity have been basically dried and the clothes processing equipment has entered the cooling stage S3, at which point the constant speed stage S2 can be determined to have ended. In this case, the heating component can be turned off while the compressor continues to run. Specific adjustments can be made according to actual needs, and this disclosure does not limit this.

[0115] If not, and it is determined that the clothes in the clothing container cavity have not yet completed the drying, heating and / or constant speed stages, then the heating components and compressor will continue to operate.

[0116] It should be noted that at the beginning of the drying process, the temperature of the circulating air in the drying duct is relatively low. Therefore, operating the compressor at a higher initial frequency ensures higher compressor speed and compression efficiency, thus improving the drying efficiency of the garment processing equipment. After drying for a period of time, as the temperature of the circulating air rises, reducing the compressor frequency to a lower frequency prevents the drying temperature from rising too quickly and triggering overheat protection. This allows the garment processing equipment to maintain high-efficiency drying for a longer period, effectively increasing the drying speed.

[0117] In one possible implementation, referring to Figure 4, after determining that the drying temperature has reached a threshold temperature and controlling the operation of the fresh air device to introduce ambient air into the drying duct of the clothing processing equipment, the control method further includes:

[0118] Step 140: Determine that the drying temperature has reached its limit and reduce the operating frequency of the compressor.

[0119] In this embodiment, the extreme temperature is greater than the aforementioned threshold temperature. The extreme temperature is set by relevant technicians according to actual needs. Specifically, when the drying temperature is determined to reach the extreme temperature, the garment processing equipment will trigger over-temperature protection. The extreme temperature refers to the lowest temperature at which the garment processing equipment triggers over-temperature protection. For example, the extreme temperature can be 90°C, 88°C, 95°C, or other possible temperature values. This embodiment does not limit this.

[0120] Understandably, for example, if the operating parameters of the fresh air unit cannot be adjusted, then when the drying temperature reaches its limit, the operating frequency of the compressor can be directly reduced.

[0121] For example, if the operating parameters of the fresh air system are adjustable, the compressor's operating frequency can be reduced once the drying temperature is determined to have reached its limit. Alternatively, the operating parameters of the fresh air system can be adjusted first to increase the amount of ambient air introduced. Furthermore, if the drying temperature remains above or equal to the limit temperature even after adjusting the operating parameters of the fresh air system until the amount of ambient air introduced reaches its maximum value, the compressor's operating frequency can then be reduced. This application does not limit this approach.

[0122] It is worth noting that if the drying temperature still rises to the limit temperature even when the fresh air device introduces cooler ambient air into the drying duct, it indicates that even with the introduction of ambient air through the fresh air device, the drying temperature cannot be effectively controlled. In this case, it is necessary to reduce the operating frequency of the compressor to decrease the heat released by the condenser onto the circulating air in the drying duct and lower the temperature of the circulating air. This prevents the garment processing equipment from being in an overheated state for an extended period, thereby improving the safety and practicality of the control method for the garment processing equipment.

[0123] In one possible implementation, the control method further includes:

[0124] Once the drying process is complete, stop the operation of the fresh air unit.

[0125] It should be noted that once the drying process ends, it indicates that the garment processing equipment has completed the drying work. This means that 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 duct. 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.

[0126] In one possible implementation, referring to Figure 5, after controlling the operation of the fresh air device to introduce ambient air into the drying duct of the clothing processing equipment, the control method includes:

[0127] Step 150: If the drying temperature is less than the target temperature within the preset time, reduce the air intake provided by the fresh air device.

[0128] In this embodiment, the preset time is set by relevant technical personnel according to actual needs. Generally, a shorter preset time can be set to avoid the clothing processing equipment from operating for a long time at a drying temperature lower than the target temperature.

[0129] In this embodiment, the target temperature is used to characterize the temperature at which the garment processing equipment is in optimal drying condition, or to characterize the temperature at which the garment processing equipment dries the garments in the garment processing chamber as quickly as possible.

[0130] Specifically, the target temperature is greater than the aforementioned threshold temperature but less than the limit temperature.

[0131] It is worth noting that reducing the air intake provided by the fresh air device can be done by making the amount of ambient air introduced by the fresh air device less than the current air intake, or by making the fresh air device stop introducing ambient air. The specific adjustments can be made according to actual needs, and this application does not limit this.

[0132] One possible approach is to assume that the fresh air unit is a damper that can be opened or closed by a drive component. In this case, when reducing the amount of air supplied through the fresh air unit, the degree of opening of the damper can be reduced by the drive component, or the damper can be closed directly by the drive component.

[0133] Another possible approach is to assume that the fresh air device is an air supply mechanism similar to a blower. In this case, reducing the air intake provided by the fresh air device can be achieved by reducing the output power of the air supply mechanism or by directly controlling the air supply mechanism to stop supplying air. This application does not limit this approach.

[0134] It's worth noting that the target temperature represents the temperature at which the garment processing equipment operates at its optimal drying condition. In other words, when the drying temperature is greater than or equal to the target temperature, the garment processing equipment can dry more efficiently. However, if the ambient air temperature is too low, the drying temperature may remain below the target temperature for the preset time, preventing the garment processing equipment from operating at its optimal drying condition. Therefore, reducing the airflow supplied through the fresh air unit can appropriately increase the drying temperature, ensuring it is greater than or equal to the target temperature, thereby effectively increasing the drying speed.

[0135] Furthermore, reducing the air intake from the fresh air unit may cause the drying temperature to continue rising. If the drying temperature exceeds the target temperature, the air intake from the fresh air unit can be appropriately increased to prevent the drying temperature from continuing to rise and triggering over-temperature protection. Therefore, this application embodiment also provides a possible implementation method, which further includes:

[0136] Once the drying temperature is determined to be at its limit, the air intake provided by the fresh air device is increased.

[0137] In this embodiment, the drying temperature reaching the limit temperature can mean that the drying temperature is equal to or greater than the limit temperature, or it can mean that the drying temperature is within the error range of the limit temperature.

[0138] It is worth noting that if the drying temperature is determined to have reached its limit, it indicates that the drying temperature has continued to rise to the point that triggers over-temperature protection, even with the fresh air unit reducing its air intake or stopping operation. In this case, it is necessary to lower the drying temperature. Therefore, it is necessary to increase the air intake provided by the fresh air unit.

[0139] One possible approach is to assume that the fresh air unit is a damper that can be opened or closed by a drive component. When increasing the air intake provided by the fresh air unit, if the damper is not open, then the damper is opened; if the damper is not yet open to its maximum extent, then the degree of opening of the damper can be increased by the drive component.

[0140] Another possible approach is to assume that the fresh air device is an air supply mechanism. If the air supply mechanism is not working or its current power is less than its rated power, then by increasing the air intake provided by the fresh air device, the air supply mechanism can be controlled to start working or its output power can be increased. This application does not limit this approach.

[0141] As can be seen, in this embodiment, the air intake provided by the fresh air device can be flexibly adjusted according to the drying temperature. This can prevent the clothing processing equipment from overheating or failing to operate under optimal drying conditions, thereby ensuring the flexibility and practicality of the control method for the clothing processing equipment.

[0142] In one possible implementation, controlling the operation of the fresh air unit includes:

[0143] If the ambient temperature is determined to be less than or equal to the ambient temperature threshold, the fresh air device is controlled to operate according to the switching rhythm corresponding to the ambient temperature.

[0144] In this embodiment, the ambient temperature threshold can be set by relevant technical personnel according to actual needs. Similarly, the switching cycle time can be set by relevant technical personnel according to actual needs. For example, the switching cycle time can be the ratio of the operating time to the off time of the fresh air system. Generally, the lower the ambient temperature, the smaller the corresponding switching cycle time, meaning a smaller ratio of the operating time to the off time of the fresh air system, which is equivalent to a larger proportion of the fresh air system's off-time within a given period.

[0145] In some implementations, the correspondence between ambient temperature and switching cycles can be pre-stored. If the ambient temperature is determined to be less than or equal to an ambient temperature threshold, the corresponding switching cycle for the current ambient temperature can be found, and the fresh air unit can be controlled to operate according to the switching cycle corresponding to the ambient temperature. When the fresh air unit operates according to this switching cycle, ambient air can be intermittently introduced into the drying duct.

[0146] It is worth noting that in this case, determining that the ambient temperature is less than or equal to the ambient temperature threshold indicates that the current ambient temperature and the temperature of the ambient air introduced into the drying duct are both relatively low. Therefore, if a large amount of ambient air is introduced through the fresh air device, it may lead to a significant decrease in the drying temperature.

[0147] It is worth noting that by controlling the fresh air device to operate according to the switching rhythm, the amount of ambient air introduced by the fresh air device can be appropriately reduced, the drying temperature can be prevented from dropping significantly, and thus ensured that the drying speed of the clothing processing equipment will not decrease due to the ambient temperature being too low.

[0148] In one possible implementation, referring to Figure 6, activating the compressor, heating assembly, and circulating air includes:

[0149] Step 1101: Determine that the working mode of the garment processing equipment is the quick drying mode, run the drying program corresponding to the quick drying mode, and turn on the compressor, the heating component and the circulating air according to the parameters indicated by the drying program.

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

[0151] Generally speaking, the quick drying mode refers 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 the garment.

[0152] Slow drying mode refers to a mode that involves slow drying, longer drying time, and lower drying efficiency. In this mode, the compressor of the garment processing equipment operates at a low frequency, and the heating components do not need to be heated.

[0153] Standard drying mode refers to a mode that performs 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.

[0154] In addition, during the drying process, the aforementioned fan can generally be kept running continuously so that the circulating air in the drying duct can flow in the aforementioned channel b.

[0155] 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 application can only be set in the form of the above examples.

[0156] It is worth noting that once the clothing processing equipment is set to the fast drying mode, the drying program corresponding to the fast drying mode can be reliably controlled to keep the compressor, evaporator, condenser and heating components in the clothing processing equipment working continuously, so as to quickly increase the temperature of the circulating air in the drying duct, thereby achieving the purpose of increasing the drying speed.

Industrial applicability

[0171] This disclosure discloses a control method, apparatus, storage medium, and device for a garment processing equipment.

The control method includes: turning on the compressor, heating element, and circulating air to dry the garments; determining that the drying temperature has reached a threshold temperature; controlling the operation of a fresh air device to introduce ambient air into the drying duct; and maintaining the operation of the heating element. In this way, because the ambient air temperature is relatively low, the rate of increase in drying temperature is slowed down, preventing the garment processing equipment from triggering overheat protection too quickly, thus allowing the garment processing equipment to maintain high-efficiency drying for a longer period. This effectively improves the drying speed and has strong industrial applicability.
