[0066] Example 1

[0067] like Figure 1 As shown, this embodiment provides a clothes processing device, including:

[0068] The outer tube 3, the tube wall of the outer tube 3 is provided with a first air outlet and a second air outlet, and the tube mouth of the outer tube 3 is provided with a first air inlet and a second air inlet; specifically, the first air outlet and the second air outlet are formed on the upper side of the tube wall of the outer tube 3, and a door seal is provided at the tube mouth of the outer tube 3, and the door seal forms a first air inlet duct and a second air inlet duct connected with the outer tube 3, and the first air inlet duct is formed at one end away from the outer tube 3, and the second air inlet duct is formed at one end away from the outer tube 3;

[0069] The first air duct 11 and the second air duct 21; the first air duct 11 is connected between the first air outlet and the first air inlet, and the second air duct 21 is connected between the second air outlet and the second air inlet; specifically, the first air duct 11 and the second air duct 21 are arranged at intervals along the circumference of the outer tube 3;

[0070] The first fan 12 and the second fan 22, the first fan 12 is arranged in the first air duct 11 and close to the first air outlet; the second fan 22 is arranged in the second air duct 21 and close to the second air outlet; the first fan 12 is used to circulate the drying air flow between the first air duct 11 and the outer cylinder 3, and the second fan 21 is used to circulate the drying air flow between the second air duct 21 and the outer cylinder 3;

[0071] Evaporator 13, condenser 23 and sprayer 24; evaporator 13 is arranged in the first air duct 11 and between the first fan 12 and the first air inlet, and evaporator 13 can dehumidify the drying airflow flowing through the first air duct 11; condenser 23 and sprayer 24 are both arranged in the second air duct 12, condenser 23 is close to the second air inlet, and condenser 23 can heat the drying airflow flowing through the second air duct 21; sprayer 24 is close to the second fan 22, and condensed water sprayed by sprayer 24 can dehumidify the drying airflow flowing through the second air duct 21; specifically, sprayer 24 is located upstream of condenser 23;

[0072] The evaporator 13 and the condenser 23 are respectively arranged in two air ducts, and the remaining space on the top of the clothing processing equipment is reasonably utilized. The number of rows of the evaporator 13 and the condenser 23 are increased, the volume of the two devices is increased, the drying performance is improved, and the air duct structure is simplified at the same time; the evaporator 13 in the first air duct 11 can dehumidify the drying air flow flowing through, and the sprayer 24 in the second air duct 21 sprays condensed water to dehumidify the drying air flow flowing through. The two work together to enhance the dehumidification effect of the drying air flow, thereby improving the drying efficiency of the clothes; the first fan 12 pushes the air flow in the first air duct 11, and the second fan 22 pushes the air flow in the second air duct 21, so that the drying air flow forms a stable and efficient circulation path in the equipment, ensuring that the drying air flow acts evenly on the clothes, thereby improving the uniformity of the drying effect.

[0073] Specifically, the clothing processing equipment is a heat pump washing machine or dryer or a washing and drying machine; the sprayer 24 is connected to an inlet valve 26 through an inlet pipe 25, and the flow rate of condensed water sprayed by the sprayer 24 can be controlled by the inlet valve 26; temperature sensors 4 are provided at the first air inlet and the second air inlet, which are used to detect the temperature of the drying airflow at the first air inlet and the second air inlet.

[0074] Furthermore, the clothes processing device further comprises a controller, which can adjust the frequencies of the first fan 12 and the second fan 22 according to the drying stage of the clothes processing device, and / or control the start and stop of the sprayer 24.

[0075] like Figure 2 As shown, this embodiment further provides a drying method for a clothes processing device, the clothes processing device is any of the clothes processing devices described above; the clothes processing device is provided with a drying program, and the drying degree includes at least one of a heating and temperature rising stage, a constant temperature dehumidification stage and a dryness judging stage which are sequentially operated in chronological order; the drying method includes:

[0076] S1, determining the current drying stage of the clothes processing equipment;

[0077] S2, adjusting the frequencies of the first fan 12 and the second fan 22 according to the current drying stage, and / or controlling the start and stop of the sprayer 24 according to the current drying stage;

[0078] The current drying stage is one of a heating and temperature rise stage, a constant temperature dehumidification stage, and a dryness determination stage;

[0079] In this way, according to the current drying stage of the clothing processing equipment, the frequency of the two fans is adjusted and the start and stop of the sprayer 24 is controlled, so as to accurately operate each stage of the drying process, so that the equipment can operate in the most suitable working state at each stage, meet the needs of airflow and dehumidification at different stages, improve the drying efficiency, and realize the automation and intelligence of the drying process.

[0080] When the current drying stage is the heating stage, S2 includes:

[0081] S21, adjusting the frequency of the first fan 12 to be within a first preset frequency range and adjusting the frequency of the second fan 22 to be within a second preset frequency range;

[0082] Wherein, the maximum threshold of the first preset frequency interval is less than the minimum threshold of the second preset frequency interval;

[0083] Thus, an evaporator 13 is provided in the first air duct 11, and its main function is to dehumidify the drying airflow; the lower frequency of the first fan 11 can make the airflow have a relatively long residence time in the first air duct 11, so that the evaporator 13 has more sufficient time to dehumidify the airflow, thereby ensuring that the humidity of the airflow entering the outer drum 3 is low, creating good conditions for the subsequent drying process; the operating frequency of the second fan 22 is relatively high, which can make the airflow speed in the second air duct 21 faster; since a condenser is provided in the second air duct 21, a higher airflow speed can speed up the circulation of hot air, so that more heat can be quickly transferred to the clothes in the outer drum 3, thereby increasing the heating speed of the clothes, effectively shortening the time required for the heating stage, and improving the drying efficiency;

[0084] This setting of different frequencies in different air ducts allows the functions of the two air ducts to be more fully utilized, and can maintain a stable airflow environment during the heating stage; the stable airflow speed and distribution help to make the drying airflow act evenly on the clothes, avoiding the situation where the clothes heat up too quickly or too slowly in some areas due to unstable airflow, thereby improving the drying effect and ensuring the drying quality of the clothes; shortening the drying time, reducing the energy consumption per unit drying amount, and improving energy utilization efficiency.

[0085] When the current drying stage is the constant temperature dehumidification stage, S2 includes:

[0086] S22, adjusting the frequency of the first fan 12 to be within a third preset frequency interval and adjusting the frequency of the second fan 22 to be within a fourth preset frequency interval;

[0087] Among them, the minimum threshold of the third preset frequency interval and the minimum threshold of the fourth preset frequency interval are both greater than the maximum threshold of the first preset frequency interval; the minimum threshold of the third preset frequency interval is greater than the maximum threshold of the second preset frequency interval, and the maximum threshold of the fourth preset frequency interval is less than the minimum threshold of the second preset frequency interval.

[0088] In this way, the speed of the first fan 12 is increased in the constant temperature dehumidification stage, which speeds up the airflow circulation speed in the first air duct 11, thereby enhancing its dehumidification effect on the drying airflow, more efficiently removing the water vapor in the airflow, and creating favorable conditions for dehumidifying clothes; the speed of the second fan 22 is reduced in the constant temperature dehumidification stage, which can accurately control the speed and amount of the hot airflow heated by the condenser 23 in the second air duct 21 entering the outer drum 3, thereby maintaining the temperature in the outer drum 3 stable and avoiding damage to the clothes caused by excessive temperature;

[0089] Different fan frequency settings make the air flow speed and distribution in the first air duct 11 and the second air duct 21 more in line with the requirements of the constant temperature dehumidification stage; reasonable air flow distribution can make the drying airflow act on the clothes more evenly, avoiding local over-drying or under-drying, and improving the uniformity and overall quality of clothing drying.

[0090] When the current drying stage is the constant temperature dehumidification stage, S2 also includes:

[0091] S231, obtaining a first inlet air humidity, a first outlet air humidity, a second inlet air humidity, and a second outlet air humidity;

[0092] S232, calculating a first inlet and outlet air humidity difference and a second inlet and outlet air humidity difference;

[0093] S233, comparing the first inlet and outlet air humidity difference and the second inlet and outlet air temperature difference;

[0094] S234, when the first inlet and outlet air humidity difference is greater than or equal to the second inlet and outlet air temperature difference, adjusting the frequency of the first fan 12 to be greater than or equal to the frequency of the second fan 22;

[0095] S235, when the first inlet and outlet air humidity difference is less than the second inlet and outlet air temperature difference, adjusting the frequency of the first fan 12 to be less than the frequency of the second fan 22;

[0096] Among them, the first inlet humidity is the humidity of the drying airflow at the first air inlet, the first outlet humidity is the humidity of the drying airflow at the first air outlet, and the first inlet and outlet humidity difference is the first inlet humidity minus the first outlet humidity; the second inlet humidity is the humidity of the drying airflow at the second air inlet, the second outlet humidity is the humidity of the drying airflow at the second air outlet, and the second inlet and outlet humidity difference is the second inlet humidity minus the second outlet humidity;

[0097] In this way, when the first inlet and outlet humidity difference is greater than or equal to the second inlet and outlet humidity difference, it means that the dehumidification task of the first air duct 11 is heavier. At this time, adjusting the frequency of the first fan 12 to be greater than or equal to the frequency of the second fan 22 can speed up the air circulation in the first air duct 11 and enhance the dehumidification capacity of the evaporator 13; conversely, when the first inlet and outlet humidity difference is less than the second inlet and outlet humidity difference, increase the frequency of the second fan 22 to enhance the dehumidification effect of the sprayer 24 in the second air duct 21; this method of dynamically adjusting the fan frequency according to the actual humidity difference can enable the equipment to more accurately meet the dehumidification needs of different air ducts; by comparing the inlet and outlet humidity difference and adjusting the fan frequency, the dehumidification effects of the two air ducts can be made more balanced, avoiding the situation where some clothes are over-dry and some clothes are not dry, thereby improving the uniformity and overall quality of clothing drying.

[0098] In addition, S2 includes:

[0099] S241, when the current drying stage is the constant temperature dehumidification stage, control the sprayer 24 to open;

[0100] S242, when the current drying stage is the dry stage, control the sprayer 24 to be closed;

[0101] In this way, in the constant temperature dehumidification stage, the moisture content of the clothes is relatively high. At this time, the sprayer 24 is turned on, and the condensed water sprayed by the sprayer 24 can dehumidify the drying airflow flowing through the second air duct 21; by reducing the humidity of the drying airflow, it can more effectively absorb moisture from the clothes, accelerate the drying process of the clothes, and improve the dehumidification efficiency of the entire constant temperature dehumidification stage; in the dry judgment stage, the clothes are close to a dry state, and the sprayer 24 is turned off at this time; because continuing to run the sprayer will not only fail to significantly improve the drying effect, but also consume additional energy and water resources.

[0102] When the shower 24 is turned on, the drying method further comprises:

[0103] S31, obtaining a second inlet air humidity and a second outlet air humidity;

[0104] S32, calculating the second inlet and outlet humidity difference;

[0105] S33, adjusting the flow rate of condensed water sprayed by the sprayer 24 according to the second inlet and outlet air humidity difference;

[0106] The second inlet humidity is the humidity of the drying airflow at the second inlet, the second outlet humidity is the humidity of the drying airflow at the second outlet, and the second inlet and outlet humidity difference is the second inlet humidity minus the second outlet humidity.

[0107] In this way, the second inlet humidity and the second outlet humidity are obtained and the humidity difference is calculated, which can reflect the actual dehumidification situation of the drying airflow in the second air duct; the condensation water flow rate sprayed by the sprinkler 24 is adjusted according to this humidity difference, so that the amount of condensation water can be accurately matched with the actual dehumidification demand; when the second inlet and outlet humidity difference is large, it means that the dehumidification demand is high. At this time, increasing the condensation water flow rate can enhance the dehumidification effect; conversely, when the humidity difference is small, reduce the condensation water flow rate to avoid excessive dehumidification.

[0108] This embodiment further proposes that S1 includes:

[0109] S11, obtaining a second inlet air temperature;

[0110] S12, comparing the second air inlet temperature with the first preset temperature;

[0111] S13, when the second air inlet temperature is lower than the first preset temperature, determining that the current drying stage is a heating and temperature rise stage;

[0112] S14, when the second air inlet temperature is greater than or equal to the first preset temperature, determining that the current drying stage is a constant temperature dehumidification stage;

[0113] The second air inlet temperature is the temperature of the drying airflow at the second air inlet.

[0114] S1 also includes:

[0115] S15, obtaining a first air inlet temperature, a first air outlet temperature, a first air inlet temperature, and a first air outlet temperature;

[0116] S16, calculating a first inlet and outlet air temperature difference and a second inlet and outlet air temperature difference;

[0117] S17, comparing the first inlet and outlet air temperature difference with the second preset temperature and the second inlet and outlet air temperature difference with the second preset temperature;

[0118] S18, when the first inlet and outlet air temperature difference is less than the second preset temperature and the second inlet and outlet air temperature difference is less than the second preset temperature, determining that the current drying stage is a drying stage;

[0119] Among them, the first inlet temperature is the temperature of the drying airflow at the first air inlet, the first outlet temperature is the temperature of the drying airflow at the first outlet, and the first inlet and outlet temperature difference is the first inlet temperature minus the first outlet temperature; the second inlet temperature is the temperature of the drying airflow at the second inlet, the second outlet temperature is the temperature of the drying airflow at the second outlet, and the second inlet and outlet temperature difference is the second inlet temperature minus the second outlet temperature.

[0120] This embodiment also provides an electronic device, including a memory and a processor, wherein the memory is used to store a computer program; and the processor is used to execute the computer program to implement any of the above-mentioned drying methods for the clothing processing device.

[0121] Example 2

[0122] like Figure 3 As shown, different from Example 1, the drying method in this embodiment is to achieve rapid heating in the heating stage and efficient dehumidification in the constant temperature dehumidification stage by controlling the frequency of the first fan 12 and the second fan 22 and the operation of the sprayer 24 in the heating stage and the constant temperature dehumidification stage, thereby improving the drying effect and shortening the drying time;

[0123] Specifically, when it is detected that the clothes processing device enters the drying stage, the temperature of the drying airflow at the second air inlet (the second air inlet temperature) is detected in real time. When the second air inlet temperature is less than the first preset temperature, it is determined that the clothes processing device is in the heating and temperature rising stage. Since the temperature of the evaporator 13 is low in the heating and temperature rising stage, the low-frequency operation of the first fan 12 is conducive to drying and temperature rising, while reducing noise; the high-frequency operation of the second fan 22 realizes rapid temperature rising;

[0124] When the second air inlet temperature is greater than or equal to the first preset temperature, it is determined that the clothing processing device is in the constant temperature dehumidification stage.
