Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.

[0037] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0038] With the continuous improvement of living standards, clothing processing equipment with drying function is loved by more and more users. For example, clothing processing equipment with drying function can be a washing and drying machine and a drying machine. The clothing processing equipment with drying function not only solves the problem that clothes cannot be dried after washing on rainy days, but also can dry and dehumidify clothes in humid weather. In the related art, in order to ensure the drying speed, the clothing processing equipment with drying function usually sets the drying temperature of the clothing processing equipment to a high level, and the drying temperature can even reach about 70 degrees Celsius. In order to avoid scalding the user due to the high temperature of the drying airflow when the clothing processing equipment is used, during the drying stage, the user is not allowed to open the door of the clothing processing equipment when the clothes have just been dried. It is necessary to wait until the temperature of the clothes drops to a safe range before the drying stage can be ended, and the user can open the door to take out the clothes. However, this will cause the drying stage of the clothing processing equipment to take too long, and the user's waiting time will also increase, affecting the user's experience of using the clothing processing equipment.

[0039] According to a first aspect of the embodiment of the present disclosure, Figure 1 and Figure 2As shown, a control method is provided for a clothing processing device with a drying function, the clothing processing device having a drum for accommodating clothing, and a first cavity for storing gas is arranged in the clothing processing device, the control method comprising: step S100: controlling the clothing processing device to perform a drying stage; step S200: in the drying stage, according to the environmental parameters in the drum, controlling the clothing processing device to selectively perform a first cooling treatment and a second cooling treatment on the drum, so that the clothing processing device ends the drying stage and reduces the temperature of the gas in the drum to a target temperature; wherein the first cooling treatment comprises inputting a gas having a temperature less than or equal to the target temperature into the drum of the clothing processing device, and the second cooling treatment comprises recovering the gas in the drum into the first cavity and inputting a gas having a temperature less than or equal to the target temperature.

[0040] Through the above technical solution, when the drying stage is executed, the drying state of the clothes can be fed back through the environmental parameters of the drum. For example, through the environmental parameters of the drum, it can be judged whether the clothes have just been dried. When the clothes have just been dried, the temperature in the drum is high, and it is necessary to avoid opening the door of the clothes processing device. At this time, through the first cooling process or the second cooling process, the clothes processing device ends the drying stage and makes the temperature of the gas in the drum reach the target temperature. The target temperature here can be a temperature that the user can accept, so that the user can open the door of the clothes processing device faster, avoiding the user's waiting. Compared with the related art, the user needs to wait until the temperature of the clothes drops to a safe range before the drying stage can be ended and the door can be opened. The present application can judge the drying state of the clothes through the environmental parameters in the drum. Further, through the drying state of the clothes, through the first cooling process or the second cooling process, the clothes processing device ends the drying stage and makes the temperature of the gas in the drum reach the target temperature, ensuring that the time taken for the drying stage of the clothes processing device will not be too long, and also reducing the time for the user to wait for the door to be opened after the clothes are dried, ensuring the user's experience of using the clothes processing device. At the same time, in the second cooling treatment, the gas in the cylinder can be recovered and input first, and the second cooling treatment can make the temperature of the gas in the cylinder reach the target temperature more quickly. In this way, after judging the drying state of the clothes, the clothes processing equipment can be controlled to selectively perform the first cooling treatment and the second cooling treatment according to the drying state of the clothes to avoid energy waste. At the same time, in the second cooling treatment, the gas in the cylinder can be recovered to the first cavity, and the first cavity can be connected to the cylinder, so that when the gas needs to be used or supplemented in the cylinder, the recovered gas can be passed into the cylinder to realize the utilization of the gas, so that the clothes processing equipment will be more energy-efficient when used. In addition, the recovery of gas during the second cooling treatment can prevent the hot and humid gas in the cylinder from entering the external environment, avoid affecting the external environment, and also avoid the connection between the gas in the cylinder and the external environment, so as to avoid the gas in the external environment from affecting the balance of the gas in the cylinder.

[0041] The target temperature mentioned above and below can be the temperature at which the user can open the door of the clothing processing device, that is, the temperature at which the user is allowed to open the door of the clothing processing device. Generally speaking, the target temperature can be room temperature. Generally speaking, room temperature is generally in the range of 16 to 27 degrees. At this time, the target temperature can be selected within the range of 16 to 27 degrees. The target temperature can also be a temperature close to human body temperature. Generally speaking, human body temperature is generally in the range of 35 to 37 degrees. At this time, the target temperature can be selected within the range of 35 to 37 degrees. In this way, it is ensured that the user will not be scalded when opening the door of the clothing processing device. In the present application, the specific value of the target temperature is not limited, and it can be adaptively designed according to the different clothing processing equipment and actual conditions.

[0042] The first cavity mentioned above can be connected to the cylinder, so that when the gas needs to be used or supplemented in the cylinder, the recovered gas can be passed into the cylinder to realize the utilization of the gas. This can be achieved by a pressurizing device arranged in the first cavity, or when recovering the gas, a certain pressure can be allowed to exist in the first cavity. In this way, when the gas needs to be used or supplemented in the cylinder, the gas will have sufficient pressure to be discharged from the first cavity and be further utilized.

[0043] Step S200 may include step S201: according to the temperature of the gas in the drum, control the clothes processing device to selectively perform the first cooling treatment and the second cooling treatment on the drum, so that the clothes processing device ends the drying stage and the temperature in the drum is reduced to the target temperature. The drying state of the clothes can be fed back through the temperature in the drum, and further, the drum can be cooled at an appropriate time. While ensuring that the clothes can be dried, the temperature of the gas in the drum and the temperature of the clothes in the drum can be quickly reduced, so that the user can open the door of the clothes processing device more quickly after the clothes are dried, avoiding the user's waiting and ensuring the user's experience of using the clothes processing device.

[0044] Specifically, when the temperature of the gas in the drum is greater than the target temperature and less than or equal to the first preset value, the laundry processing device is controlled to perform a first cooling treatment on the drum until the temperature of the gas in the drum is less than or equal to the target temperature; or, when the temperature of the gas in the drum is greater than the first preset value, the laundry processing device is controlled to perform a second cooling treatment on the drum until the temperature of the gas in the drum is less than or equal to the target temperature, wherein the first preset value is greater than the value of the target temperature. The first preset value here can be less than the value of the temperature of the drying airflow when the laundry processing device dries the clothes when it is stable. Stable here means that the temperature of the drying airflow can fluctuate within a small range. On this basis, a value selected within the fluctuation range, the first preset value is less than the selected value. According to different specifications of the laundry processing device, the value of the temperature of the drying airflow when it is stable is also different. For example, when the value of the temperature of the drying airflow when it is stable is 60 degrees and the target temperature is 25 degrees, the first preset value can be 50 degrees.

[0045] When the temperature of the gas in the cylinder is greater than the target temperature and less than or equal to the first preset value, it means that the clothes have been dried for a period of time. At this time, the temperature of the gas in the cylinder does not exceed the first preset value. The temperature of the gas in the cylinder exceeds the range acceptable to the human body but is not too high. If the gas with a temperature less than or equal to the target temperature is not provided to the cylinder, the user needs to wait for the temperature of the clothes in the cylinder to naturally drop to a suitable temperature before opening the door of the clothing treatment device, but the user has to wait for a long time. At this time, the clothing treatment device can be controlled to perform the first cooling treatment on the cylinder until the temperature of the gas in the cylinder is less than or equal to the target temperature. This allows the user to open the door of the clothing treatment device more quickly after the clothes are dried, avoiding the user's waiting and ensuring the user's experience of using the clothing treatment device. Since the temperature of the gas in the cylinder is not too high, the first cooling treatment can be used to quickly cool the cylinder without recovering the gas in the cylinder, which can avoid energy waste.

[0046] When the temperature of the gas in the cylinder is greater than the first preset value, it means that the clothes have just been dried. At this time, the temperature of the gas in the cylinder far exceeds the range acceptable to the human body. The temperature of the gas in the cylinder is too high. At this time, the clothing processing equipment is controlled to perform a second cooling treatment on the cylinder until the temperature of the gas in the cylinder is less than or equal to the target temperature. Since the temperature of the gas in the cylinder is too high, it is necessary to quickly reduce the temperature of the gas in the cylinder to the target temperature through the second cooling treatment during the cooling treatment. At this time, through the second cooling treatment, the gas in the cylinder can be recovered and the gas with a temperature less than or equal to the target temperature can be input to quickly reduce the temperature of the gas in the cylinder to the target temperature. In the second cooling treatment, the gas can be input while the gas is recovered, or it can be input after the gas is recovered.

[0047] In some embodiments, when the temperature of the gas in the cylinder is greater than the first preset value, before controlling the laundry processing device to perform the second cooling treatment, the control method of the present application further includes: determining whether to perform cooling pretreatment according to the humidity of the gas in the cylinder, the cooling pretreatment including inputting gas with a temperature greater than the first preset value into the cylinder of the laundry processing device, or inputting gas with a temperature greater than the first preset value and a humidity less than the second preset value into the cylinder of the laundry processing device. When the temperature of the gas in the cylinder is greater than the first preset value, before controlling the laundry processing device to perform the second cooling treatment, the laundry processing device can be controlled to first perform cooling pretreatment on the cylinder according to the humidity of the gas in the cylinder, and then perform the second cooling treatment on the cylinder until the temperature of the gas in the cylinder is less than or equal to the target temperature. When the temperature of the gas in the cylinder is greater than the first preset value, it means that the clothes have just been dried. At this time, the drying state of the clothes, that is, whether the clothes have been dried, can be judged according to the humidity of the gas in the cylinder. According to the humidity of the gas in the cylinder, the clothes can have two drying states, one drying state is that the clothes are dried but the temperature of the gas in the cylinder is still very high, and the other drying state is that the clothes are still wet and the clothes are not dried. Therefore, when the temperature of the gas in the drum is greater than the first preset value, it is necessary to further judge the drying state of the clothes according to the humidity of the gas in the drum. When the clothes are not dried, the drying stage cannot be ended due to the cooling treatment. At this time, the clothes processing equipment can be controlled to pre-cool the drum. In the cooling pre-treatment, a gas with a temperature greater than the first preset value or a temperature greater than the first preset value and a humidity less than the second preset value is input into the drum of the clothes processing equipment. This means that on the basis of the original drying airflow, an additional gas with a temperature greater than or equal to the first preset value is provided to the drum. This can quickly promote the drying of the clothes, so that the clothes can be dried completely. On the basis that the clothes are dried completely, the second cooling treatment is performed, which further improves the accuracy and efficiency of the cooling treatment.

[0048] Specifically, when the temperature of the gas in the cylinder is greater than a first preset value, if the humidity of the gas in the cylinder is greater than or equal to a second preset value, a cooling pretreatment is performed until the humidity of the gas in the cylinder is less than the second preset value.

[0049] When the temperature of the gas in the drum is greater than the first preset value and the humidity is less than the second preset value, it means that the clothes have just been dried and are in a drying state. At this time, there is no need to perform cooling pretreatment. The temperatures of the gas and clothes in the drum are respectively high, and it is necessary to avoid opening the door of the clothes processing equipment. At this time, the clothes processing equipment can be controlled to perform a first cooling treatment on the drum until the temperature of the gas in the drum is less than or equal to the target temperature. In this way, the temperature of the gas in the drum and the temperature of the clothes can be reduced to an acceptable range for the human body, and the user can quickly open the door after the clothes are dried to avoid waiting.

[0050] When the temperature of the gas in the cylinder is greater than the first preset value and the humidity is greater than the second preset value, it means that the clothes have not been dried yet, and the temperature of the gas in the cylinder and the temperature of the clothes are respectively high. It is necessary to avoid opening the door of the clothes processing device. At this time, it is necessary to ensure that the clothes are dried first to stop the drying stage as soon as possible to avoid the running time of the drying stage being too long and causing the user to wait too long, that is, it is necessary to perform cooling pretreatment first, and then perform the second cooling treatment. In this way, on the basis of the original drying airflow, additional gas with a temperature greater than or equal to the first preset value is provided to the cylinder, which can quickly promote the drying of clothes. After the clothes are dried, the second cooling treatment is performed on the cylinder until the temperature of the gas in the cylinder is less than or equal to the target temperature. In this way, after ensuring that the clothes are dried, the temperature of the gas in the cylinder and the temperature of the clothes can be directly reduced to a range acceptable to the human body, avoiding the user's waiting. When the temperature and humidity of the gas in the cylinder are respectively low, it means that the clothes have been dried and a period of time has passed. At this time, the user can directly open the door of the clothes processing device.

[0051] In some embodiments, the clothing treatment device may be provided with a heat exchange component capable of generating gas having a temperature less than or equal to a target temperature and a temperature greater than or equal to a first preset value; the clothing treatment device may also be provided with a second cavity for storing gas, and the control method may further include step S300: controlling the clothing treatment device to recycle the gas having a temperature less than or equal to the target temperature generated by the heat exchange component into the second cavity; and / or controlling the clothing treatment device to recycle the gas having a temperature greater than the first preset value in the drum into the first cavity; and / or controlling the clothing treatment device to recycle the gas having a temperature greater than the first preset value and a humidity less than the second preset value in the drum into the first cavity; and / or controlling the heat exchange component to generate gas having a temperature less than or equal to the target temperature and / or a temperature greater than or equal to the first preset value. In this way, the gas having a higher temperature can be stored in the first cavity, and the gas having a lower temperature can be stored in the second cavity.

[0052] Taking the clothes processing device as a clothes dryer or a clothes washer-dryer as an example, in the process of drying clothes, a heat exchanger is usually required to heat the airflow to form a drying airflow that can dry clothes. When the drying airflow flows out of the cylinder, it will carry a large amount of moisture. At this time, the heat exchanger needs to be refrigerated to condense and dehumidify the drying airflow flowing out of the cylinder. In this way, the heat exchanger can generate gas with a temperature less than or equal to the target temperature, and can also generate gas with a temperature greater than or equal to the first preset value. The clothes processing device can recover and store the gas with a temperature less than or equal to the target temperature generated by the heat exchange component when drying clothes, and can also recover and store the gas with a temperature greater than or equal to the first preset value when drying clothes. In this way, when it is necessary to control the clothes processing device to provide gas with a temperature less than or equal to the target temperature or gas with a temperature greater than or equal to the first preset value to the cylinder, the gas recovered and stored by the clothes processing device can be provided to the cylinder, which saves more energy. When the first cavity does not store gas, the heat exchanger can also generate gas of the corresponding temperature. Under the condition that the cylinder can be cooled, it is no longer necessary to set other electrical components to cool the cylinder. In the present application, the clothing processing equipment recycles and stores the gas in the first cavity. The gas recovered and stored in the current drying stage can be used in the current drying stage, or the gas recovered and stored in the current drying stage can be kept warm and provided to the drum when needed during the next drying.

[0053] As described above, when the second cooling treatment is performed, the gas can be recovered first and then introduced. The gas recovered during the second cooling treatment is a gas whose temperature is greater than the first preset value and whose humidity is less than the second preset value. At this time, the clothes processing device can be controlled to recover the gas recovered during the second cooling treatment and keep it warm, and provide it to the drum when it is dried next time and needs to be used.

[0054] The control method may further include step S400: controlling the clothes processing device to stop recycling the gas according to the pressure of the recycled and stored gas. In this way, the degree of gas storage can be judged according to the pressure of the recycled and stored gas. The higher the gas pressure is, the higher the gas content is per unit volume. That is, when the gas pressure reaches a certain value, it means that a certain degree of gas has been stored. At this time, the clothes processing device can be controlled to stop recycling the gas to avoid the problem that the stored gas pressure is too high and thus is difficult to store.

[0055] Generally speaking, the drying stage generally includes a dehumidification stage and a drying stage which are executed in sequence. The dehumidification stage is mainly used to quickly remove moisture from clothes. In the dehumidification stage, a drying airflow is introduced into the cylinder, and the heating element in the clothing processing equipment can gradually heat the drying airflow until the temperature of the drying airflow is stable. As the temperature of the drying airflow changes, the temperature of the gas in the cylinder will gradually increase until the temperature is stable, and the moisture on the clothes will be quickly removed. After the dehumidification stage runs for a certain period of time, it is necessary to enter the drying stage. In the drying stage, while ensuring that the clothes can continue to be dried, it is necessary to determine when to stop the drying stage, that is, to stop the drying stage, so as to avoid the drying stage running too long. In the drying stage, the moisture content of the clothes is usually less than a certain value at this time, indicating that the clothes are about to be dried. At this time, it is necessary to determine when to end the drying stage to end the drying stage.

[0056] Step S100 may include step S101: the drying stage may include a dehumidification stage and a drying stage which are executed in sequence; in the drying stage, according to the moisture content of the clothes in the drum, the clothes processing device is controlled to end the dehumidification stage and execute the drying stage; in the drying stage, according to the environmental parameters in the drum, the clothes processing device is controlled to selectively perform the first cooling treatment and the second cooling treatment on the drum. As described above, in the dehumidification stage, a drying airflow is introduced into the drum, and the heating element in the clothes processing device can gradually heat the drying airflow until the temperature of the drying airflow is stable. As the temperature of the drying airflow changes, the temperature of the gas in the drum will gradually increase until the temperature is stable, and the moisture on the clothes will be quickly removed. When the dehumidification stage runs for a certain time, it is necessary to enter the drying stage. In the drying stage, while ensuring that the clothes can continue to be dried, it is determined when to stop the drying stage, that is, stop the drying stage, so as to avoid the running time of the drying stage being too long. In the drying stage, the moisture content of the clothes is usually less than a certain value at this time, indicating that the clothes are about to be dried, so as to determine when to stop the drying stage. In the drying stage, the clothes processing device is controlled to selectively perform the first cooling treatment and the second cooling treatment on the drum according to the environmental parameters in the drum, so as to ensure that the user can open the door of the clothes processing device as soon as possible after the drying stage.
