[0051] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0052] According to an exemplary embodiment, this embodiment proposes a drying method for a clothing processing device. The clothing processing device of this embodiment may be a dryer with only a drying function, or may be a washer-dryer with both washing and drying functions. The clothing drying method of the clothing processing device of this embodiment is a heat pump drying method. The clothing processing device includes a heat pump system. The heat pump system includes a refrigerant circulation loop formed by a compressor, an evaporator, a throttling device, and a condenser. In a preferred embodiment, the condenser and the evaporator are integrated into one to form a two-device assembly. The drying method includes: determining the clothing drying stage, and collaboratively regulating clothing drying parameters according to the determined clothing drying stage. The clothing drying parameters include a drying air temperature threshold, air supply volume, and compressor operating frequency.

[0053] In this embodiment, different drying stages in the clothes drying process reflect the drying state of the clothes. By determining the drying stage in which the clothes processing equipment is located to coordinately control multiple drying parameters of the clothes, the dehumidification effect of the heat pump system and the clothes drying effect can be effectively improved, the drying time can be shortened, and energy consumption can be reduced. Clothes drying parameters include drying air temperature threshold, air supply volume, and compressor operating frequency. When the size of the air outlet is constant, the air supply volume can be increased by increasing the air supply speed. When the wind speed is constant, the air supply volume can be increased by increasing the air outlet area. The air supply speed and air supply volume can also be regulated at the same time.

[0054] There are many ways to determine the drying stage of clothes, for example, the drying stage of clothes is determined according to one or more of the drying time, the inlet air temperature of the drum, the outlet air temperature of the drum and the humidity of clothes. In one example, the clothes drying program includes the first drying stage, the second drying stage and the third drying stage which are executed in sequence, and the determination of the drying stage of clothes includes: obtaining the drying time and the inlet air temperature of the drum, and determining the drying stage of clothes as the first drying stage when the drying time is less than the set drying time and the inlet air temperature is less than the set inlet air temperature, determining the drying stage of clothes as the second drying stage when the drying time reaches the set drying time and the inlet air temperature is less than the set inlet air temperature, and determining the drying stage of clothes as the third drying stage when the inlet air temperature reaches the set inlet air temperature. The clothes processing device can obtain the drying time of clothes and the inlet air temperature of the drum in real time, or can obtain the drying time of clothes and the inlet air temperature of the drum once every set time. The range of setting the drying time is, for example, 10min to 60min, and the range of setting the inlet air temperature is, for example, 55℃ to 65℃. The first drying stage is, for example, a drying start-up stage, the second stage is, for example, a constant-speed drying stage in the early stage of drying, and the third stage is, for example, a late stage of drying.

[0055] This embodiment coordinates and controls the three parameters of air supply volume, air temperature, and compressor frequency in different drying stages to enhance the dehumidification effect of the heat pump system and the drying effect of clothes, shorten the drying time, and reduce the energy consumption of drying. In addition, this embodiment optimizes the clothing drying logic without changing the structure of the clothing processing equipment. The system is simple, reduces production costs, and reduces the pollution to the environment caused by moisture exhaust.

[0056] In one example, clothing drying parameters are coordinated and controlled according to determined clothing drying stages, including: supplying air into the drum at a first air supply volume in a first drying stage; supplying air into the drum at a second air supply volume in a second drying stage; and supplying air into the drum at a third air supply volume in a third drying stage; wherein the first air supply volume < the third air supply volume < the second air supply volume.

[0057] In this embodiment, the first drying stage is the drying start-up stage. In the drying start-up stage, the drying air temperature can be quickly increased by adopting a relatively low first air supply volume, so that the fabric inside the drum is quickly heated up, thereby quickly reaching the critical temperature point of free evaporation, and shortening the start-up heating time. The second stage is the constant-speed drying stage in the early stage of drying. In the constant-speed drying stage in the early stage of drying, the dehumidification capacity of the heat pump system and the evaporation of free water on the surface of the clothes in the drum are increased by adopting a relatively high second air supply volume, thereby achieving high-humidity and fast removal. The third stage is the late drying stage. In the late drying stage, a relatively low third air supply volume is adopted, so that the clothes in the drum are fully in contact with the low-speed airflow, the bound moisture inside the clothes is captured, and low-humidity removal is achieved. At the same time, reducing the air volume in the late drying stage will also lead to an increase in the drying air temperature, accelerate the evaporation of bound moisture inside the clothes, improve the drying efficiency of the clothes, and ultimately shorten the drying time. Exemplarily, the range of the first air supply volume is, for example, 150m 3 / h~200m 3 / h, the range of the second air supply volume is, for example, 280m 3 / h~360m 3 / h, the range of the third air supply volume is, for example, 220m 3 / h~280m 3 / h.

[0058] In one example, collaboratively regulating clothing drying parameters according to determined clothing drying stages also includes: determining a drying air temperature threshold as a first threshold in a first drying stage, maintaining the drying air temperature threshold as the first threshold in a second drying stage, and adjusting the drying air temperature threshold to a second threshold in a third drying stage, wherein: the first threshold < the second threshold.

[0059] In this embodiment, a lower drying air temperature threshold is used in both the drying start-up stage and the constant speed stage in the early stage of drying, so that the clothes are dried with drying air at a lower wind temperature, reducing the load of the heat pump system, avoiding the compressor from reducing the frequency due to excessive temperature, so that the compressor maintains high-frequency operation, maintains a strong dehumidification capacity, and shortens the constant speed drying time. In the later stage of drying, the drying air temperature threshold is appropriately increased to accelerate the evaporation of the bound water inside the clothes, improve the ability to capture the bound water inside the clothes and the drying efficiency of the clothes, and ultimately shorten the drying time. Exemplarily, the range of the first threshold is, for example, 65°C to 70°C, and the range of the second threshold is, for example, 72°C to 75°C.

[0060] In one example, according to the determined clothing drying stage, the coordinated control of clothing drying parameters further includes: determining the temperature difference between the drying air temperature threshold and the inlet air temperature of the drum, and determining the preset temperature difference determination interval in which the temperature difference is located. The compressor frequency operation value corresponding to the preset temperature difference determination interval is determined according to the mapping relationship between the preset temperature difference determination interval and the compressor frequency operation value. Wherein, in the first drying stage and the second drying stage, the temperature difference is the difference between the first threshold and the inlet air temperature; in the third drying stage, the temperature difference is the difference between the second threshold and the inlet air temperature. Wherein: the first threshold < the second threshold. Preferably, the operating frequency of the compressor in the constant speed drying stage of the early drying stage is greater than the operating frequency in the late drying stage. In this embodiment, the compressor operating frequency is determined according to the temperature difference between the drying air temperature threshold and the inlet air temperature, and the coordinated control between the compressor frequency, the drying air temperature threshold, and the inlet air temperature is achieved, so that the compressor can maintain high-frequency operation when the air volume is large in the constant speed drying stage of the early drying stage to exert the maximum dehumidification capacity of the heat pump system, and the compressor reduces the frequency when the air volume is low in the late drying stage, reduces the load of the heat pump system, and avoids the compressor from shutting down due to excessive temperature.

[0061] The method for determining the mapping relationship between the preset temperature difference determination interval and the compressor frequency operation value of the present embodiment includes: the clothing processing device includes a plurality of compressor frequency gears, and each compressor frequency gear corresponds to a mapping relationship between a preset temperature difference determination interval and a compressor frequency operation value. Before the drying program is started, the ambient temperature of the clothing processing device is also obtained, and the compressor frequency gear corresponding to the ambient temperature is determined according to the mapping relationship between the preset ambient temperature interval and the compressor frequency gear, and the mapping relationship between the preset temperature difference determination interval and the compressor frequency operation value corresponding to the compressor frequency gear is determined according to the compressor frequency gear. For example, when the ambient temperature is 5°C, it is determined that the ambient temperature is in the preset temperature determination interval of the ambient temperature between 4°C and 15°C, and the compressor will operate in the first frequency gear interval. When the temperature difference between the current drying air temperature threshold and the inlet air temperature is 4°C, the compressor frequency corresponding to the preset temperature difference determination interval where this temperature difference is located is 60HZ, and the compressor is finally controlled to operate at a frequency of 60HZ. As the inlet air temperature increases, when the temperature difference between the current drying air temperature threshold and the inlet air temperature is 1°C, the compressor frequency corresponding to the preset temperature difference judgment interval of this temperature difference is 55HZ. At this time, the compressor will reduce the frequency to 55HZ.

[0062] Figure 1 is a flow chart of a drying method according to an exemplary embodiment of the present invention, referring to Figure 1 , determining a clothes drying stage, and coordinating and regulating clothes drying parameters according to the determined clothes drying stage, comprising the following steps:

[0063] S11. The clothes drying program is started and enters the first drying stage. The first threshold is used as the initial drying air temperature threshold of the drying air, and air is supplied to the drum at a first air supply volume to quickly increase the drying air temperature so that the fabric inside the drum is quickly heated up to reach the critical temperature point for rapid free evaporation, thereby shortening the startup heating time.

[0064] S12, obtaining the inlet air temperature of the cylinder, determining the first temperature difference between the first threshold value and the inlet air temperature, determining the first compressor frequency operation value corresponding to the first temperature difference according to the mapping relationship between the preset temperature difference judgment interval and the compressor frequency operation value, controlling the compressor to operate at the first compressor frequency operation value, and realizing constant speed drying with large air volume in the early stage of drying to keep the compressor running at high frequency to exert the maximum dehumidification capacity of the heat pump system;

[0065] S13. Obtain the drying time of the clothes, and enter the second drying stage when the drying time of the clothes reaches the set drying time and the inlet air temperature is lower than the set inlet air temperature, and supply air to the drum at the second air volume to improve the dehumidification capacity of the heat pump system and the evaporation of free water on the surface of the clothes in the drum, so as to achieve high humidity and fast removal. At the same time, the lower air temperature can reduce the load of the heat pump system, avoid the frequency reduction of the compressor due to excessive temperature, so that the compressor maintains high-frequency operation, maintains a strong dehumidification capacity, and shortens the constant-speed drying time in the early stage of drying.

[0066] S14. When the inlet air temperature reaches the set inlet air temperature, the third drying stage is entered, the drying air temperature threshold of the drying air is determined to be the second threshold, and air is supplied to the drum at the third air supply volume, so that the clothes in the drum are fully in contact with the low-speed airflow, and the bound moisture inside the clothes is captured to achieve low-humidity removal. At the same time, the reduction in air volume in the later stage will also cause the drying air temperature to increase, accelerate the evaporation of bound moisture inside the clothes, improve the drying efficiency of the clothes, and ultimately shorten the drying time, wherein the first threshold value is less than the second threshold value, and the first air supply volume is less than the third air supply volume and the second air supply volume.

[0067] S15. Determine a second temperature difference between the second threshold value and the inlet air temperature, determine a second compressor frequency operating value corresponding to the second temperature difference according to a mapping relationship between a preset temperature difference judgment interval and a compressor frequency operating value, control the compressor to operate at the second compressor frequency operating value, and achieve appropriate reduction of the frequency of the compressor when the air volume is low in the later stage of drying, thereby reducing the load on the heat pump system and avoiding shutdown of the compressor due to excessively high temperature.

[0068] S16, determining a third temperature difference between the inlet air temperature and the outlet air temperature. If the third temperature difference is within the set temperature difference range and is maintained for a set duration, the drying process ends.

[0069] Figure 2 This is a comparison chart of the drying time under different compressor frequency control of the embodiment of the present invention and the original model. Figure 3This is a comparison chart of the drying time under different drying air temperature thresholds between the embodiment of the present invention and the original model. Figure 2 and Figure 3 It can be seen that the drying method of this embodiment shortens the drying time by 25% and reduces the unit dehumidification energy consumption by 32% compared with the original model that does not adopt the control method of this embodiment. The compressor frequency control strategy and the drying air temperature threshold control strategy of this embodiment can significantly improve the drying efficiency, shorten the drying time, and reduce the drying energy consumption.

[0070] According to an exemplary embodiment, this embodiment proposes a control device, which includes one or more processors and a non-transitory computer-readable storage medium storing program instructions.
