[0001] This invention belongs to the field of clothing processing technology, and particularly relates to a clothing processing device, a drying method, and an electronic device. Background Technology

[0002] With the improvement of living standards, people have placed higher demands on clothing processing equipment, including faster drying speeds and better garment care.

A drying duct connects the drying air inlet and outlet, and an evaporator and condenser are installed within the drying duct.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] In the prior art, the outer cylinder wall is provided with a drying air outlet, and the outer cylinder opening is provided with a drying air inlet. A drying air duct is connected between the drying air inlet and the drying air outlet, and an evaporator and a condenser are installed in the drying air duct. The structure of the two devices is limited, which reduces the heat exchange area, resulting in reduced heat exchange efficiency and a longer drying time.

[0064] This invention creatively provides a garment processing device, including an outer cylinder, an evaporator, a condenser, and a sprayer; the outer cylinder has a first air outlet and a second air outlet on its wall, and a first air inlet and a second air inlet at its opening; a first air duct connects the first air outlet and the first air inlet, and a first fan is installed in the first air duct; a second air duct connects the second air outlet and the second air inlet, and a second fan is installed in the second air duct; the evaporator is installed in the first air duct and can dehumidify the drying airflow flowing through the first air duct; the condenser and the sprayer are both installed in the second air duct, the condenser can heat the drying airflow flowing through the second air duct; the condensate sprayed by the sprayer can dehumidify the drying airflow flowing through the second air duct;

[0065] The heat exchange area of ​​the evaporator and condenser can be appropriately increased to enhance drying performance, improve heat exchange efficiency, and shorten the drying time.

[0066] Example 1

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

[0068] The outer cylinder 3 has a first air outlet and a second air outlet on its cylinder wall, and a first air inlet and a second air inlet at its cylinder opening. Specifically, the upper side of the cylinder wall of the outer cylinder 3 has a first air outlet and a second air outlet, and the cylinder opening of the outer cylinder 3 has a door seal. The door seal forms a first air inlet channel and a second air inlet channel that communicate with the outer cylinder 3. The end of the first air inlet channel away from the outer cylinder 3 has a first air inlet, and the end of the second air inlet channel away from the outer cylinder 3 has a second air inlet.

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

[0070] A first fan 12 and a second fan 22 are provided. The first fan 12 is located in the first air duct 11 and near the first air outlet. The second fan 22 is located in the second air duct 21 and near the second air outlet. The first fan 12 is used to circulate the drying airflow between the first air duct 11 and the outer cylinder 3. The second fan 21 is used to circulate the drying airflow between the second air duct 21 and the outer cylinder 3.

[0071] The system includes an evaporator 13, a condenser 23, and a sprayer 24. The evaporator 13 is located within the first air duct 11 and between the first fan 12 and the first air inlet. The evaporator 13 can dehumidify the drying airflow flowing through the first air duct 11. The condenser 23 and the sprayer 24 are both located within the second air duct 12. The condenser 23 is close to the second air inlet and can heat the drying airflow flowing through the second air duct 21. The sprayer 24 is close to the second fan 22, and the condensate sprayed by the sprayer 24 can dehumidify the drying airflow flowing through the second air duct 21. Specifically, the sprayer 24 is located upstream of the condenser 23.

[0072] Evaporator 13 and condenser 23 are respectively installed in two air ducts, making reasonable use of the remaining space at the top of the clothing processing equipment. The number of rows of evaporator 13 and condenser 23 are increased, and the volume of the two units is increased to improve drying performance, while simplifying the air duct structure. Evaporator 13 in the first air duct 11 can dehumidify the drying airflow, and sprayer 24 in the second air duct 21 sprays condensate water to dehumidify the drying airflow. The two work together to enhance the dehumidification effect of the drying airflow, thereby improving the drying efficiency of the clothes. First fan 12 drives the airflow in the first air duct 11, and second fan 22 drives the airflow in the second air duct 21, so that the drying airflow forms a stable and efficient circulation path in the equipment, ensuring that the drying airflow acts evenly on the clothes and improving the uniformity of the drying effect.

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

[0074] Furthermore, the garment processing equipment also includes a controller, which can adjust the frequency of the first fan 12 and the second fan 22 according to the drying stage of the garment processing equipment, and / or control the start and stop of the sprayer 24.

[0075] like Figure 2 As shown, this embodiment also provides a drying method for a garment processing device, wherein the garment processing device is any of the garment processing devices described above; the garment processing device is provided with a drying program, and the drying degree includes at least one of a heating and temperature rise stage, a constant temperature dehumidification stage, and a dryness determination stage that are operated sequentially in time; the drying method includes:

[0076] S1. Determine the current drying stage of the garment processing equipment;

[0077] S2. Adjust the frequency of the first fan 12 and the second fan 22 according to the current drying stage, and / or control the start and stop of the sprayer 24 according to the current drying stage;

[0078] The current drying stage is one of the following: heating and temperature rise stage, constant temperature dehumidification stage, and dryness judgment stage.

[0079] In this way, based on the current drying stage of the garment processing equipment, the frequency of the two fans is adjusted and the start and stop of the sprayer 24 is controlled, thereby precisely operating each stage of the drying process, so that the equipment operates in the most suitable working state at each stage, meeting the airflow and dehumidification needs of different stages, improving drying efficiency, and realizing the automation and intelligence of the drying process.

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

[0081] S21. Adjust the frequency of the first fan 12 to the first preset frequency range and adjust the frequency of the second fan 22 to the second preset frequency range;

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

[0083] Thus, the first air duct 11 is equipped with an evaporator 13, whose main function is to dehumidify the drying airflow. The lower frequency of the first fan 11 allows the airflow to have a relatively longer residence time in the first air duct 11, giving the evaporator 13 more time to dehumidify the airflow and ensuring that the airflow entering the outer drum 3 has low humidity, creating favorable conditions for the subsequent drying process. The second fan 22 operates at a relatively high frequency, which enables the airflow speed in the second air duct 21 to be faster. Since the second air duct 21 is equipped with a condenser, the higher airflow speed can accelerate the circulation of hot air, allowing more heat to 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 drying efficiency.

[0084] This setting of different air ducts and frequencies allows the functions of the two air ducts to be fully utilized, maintaining a stable airflow environment during the heating and warming stage. The stable airflow speed and distribution help to ensure that the drying airflow acts evenly on the clothes, avoiding situations 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. It also shortens the drying time, reduces the energy consumption per unit drying load, and improves energy utilization efficiency.

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

[0086] S22, Adjust the frequency of the first fan 12 to the third preset frequency range and adjust the frequency of the second fan 22 to the fourth preset frequency range;

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

[0088] Thus, the first fan 12 increases its speed during the constant temperature dehumidification stage, accelerating the airflow circulation speed within the first air duct 11, which enhances its dehumidification effect on the drying airflow and removes moisture from the airflow more efficiently, creating favorable conditions for dehumidifying clothes; the second fan 22 decreases its speed during the constant temperature dehumidification stage, which can precisely control the speed and amount of hot airflow heated by the condenser 23 in the second air duct 21 entering the outer cylinder 3, thereby maintaining a stable temperature inside the outer cylinder 3 and preventing damage to clothes due to excessively high temperatures;

[0089] Different fan frequency settings make the airflow 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 airflow distribution can make the drying airflow act more evenly on the clothes, avoid local over-drying or under-drying, and improve the uniformity and overall quality of clothes drying.

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

[0091] S231. Obtain the first inlet air humidity, the first outlet air humidity, the second inlet air humidity, and the second outlet air humidity;

[0092] S232. Calculate the humidity difference between the first inlet and outlet air and the humidity difference between the second inlet and outlet air.

[0093] S233. Compare the humidity difference between the first inlet and outlet air and the temperature difference between the second inlet and outlet air.

[0094] S234. When the humidity difference between the first inlet and outlet air is greater than or equal to the temperature difference between the second inlet and outlet air, the frequency of the first fan 12 is adjusted to be greater than or equal to the frequency of the second fan 22.

[0095] S235. When the humidity difference between the first inlet and outlet air is less than the temperature difference between the second inlet and outlet air, the frequency of the first fan 12 is adjusted to be less than the frequency of the second fan 22.

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

[0097] Thus, when the humidity difference between the first inlet and outlet air is greater than or equal to the humidity difference between the second inlet and outlet air, it indicates 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 accelerate the airflow circulation in the first air duct 11 and enhance the dehumidification capacity of the evaporator 13. Conversely, when the humidity difference between the first inlet and outlet air is less than the humidity difference between the second inlet and outlet air, the frequency of the second fan 22 is increased 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 enables the equipment to more accurately meet the dehumidification needs of different air ducts. By comparing the humidity difference between the inlet and outlet air and adjusting the fan frequency, the dehumidification effect of the two air ducts can be made more balanced, avoiding the situation where some clothes are over-dried while others are not, thereby improving the uniformity and overall quality of clothes drying.

[0098] In addition, S2 also 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 judgment drying stage, control the sprayer 24 to close;

[0101] Thus, during 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 condensate 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, moisture can be absorbed from the clothes more effectively, accelerating the drying process and improving the dehumidification efficiency of the entire constant temperature dehumidification stage. During the dry testing stage, the clothes are close to being dry, so the sprayer 24 is turned off. This is because continuing to run the sprayer will not only fail to significantly improve the drying effect, but will also consume additional energy and water resources.

[0102] When the sprayer 24 is turned on, the drying method also includes:

[0103] S31. Obtain the second inlet air humidity and the second outlet air humidity;

[0104] S32. Calculate the humidity difference between the second inlet and outlet air;

[0105] S33. Adjust the flow rate of condensate sprayed by the sprayer 24 according to the humidity difference between the second inlet and outlet air;

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

[0107] Thus, by obtaining the humidity of the second inlet air and the humidity of the second outlet air and calculating the humidity difference, the actual dehumidification situation of the drying airflow in the second air duct can be reflected. Based on this humidity difference, the flow rate of condensate sprayed by the sprayer 24 can be adjusted so that the amount of condensate used is precisely matched with the actual dehumidification needs. When the humidity difference between the second inlet and outlet air is large, it means that the dehumidification demand is high. At this time, increasing the flow rate of condensate can enhance the dehumidification effect. Conversely, when the humidity difference is small, the flow rate of condensate should be reduced to avoid over-dehumidification.

[0108] This embodiment also proposes that S1 includes:

[0109] S11, Obtain the second intake air temperature;

[0110] S12. Compare the second air intake temperature with the first preset temperature;

[0111] S13. When the second air inlet temperature is lower than the first preset temperature, the current drying stage is determined to be the heating stage.

[0112] S14. When the second air inlet temperature is greater than or equal to the first preset temperature, the current drying stage is determined to be the 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. Obtain the first inlet air temperature, the first outlet air temperature, the first inlet air temperature, and the first outlet air temperature;

[0116] S16. Calculate the first inlet and outlet air temperature difference and the second inlet and outlet air temperature difference;

[0117] S17. Compare 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 respectively.

[0118] S18. When the temperature difference between the first inlet and outlet air is less than the second preset temperature and the temperature difference between the second inlet and outlet air is less than the second preset temperature, the current drying stage is determined to be the judgment drying stage.

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

[0120] This embodiment also provides an electronic device, including a memory and a processor. The memory is used to store a computer program; the processor is used to execute the computer program to implement the drying method of the clothing processing device described in any of the above embodiments.

[0121] Example 2

[0122] like Figure 3 As shown, unlike Example 1, the drying method in this example is to control the frequency of the first fan 12 and the second fan 22 and the operation of the sprayer 24 in the heating and dehumidification stages to achieve rapid heating in the heating stage and efficient dehumidification in the dehumidification stage, thereby improving the drying effect and shortening the drying time.

[0123] Specifically, when the clothing processing equipment is detected to have entered the drying stage, the temperature of the drying airflow at the second air inlet (second air inlet temperature) is monitored in real time. When the second air inlet temperature is lower than the first preset temperature, it is determined that the clothing processing equipment is in the heating stage. Since the temperature of the evaporator 13 is low in the heating stage, the low-frequency operation of the first fan 12 is beneficial to drying and heating, while reducing noise. The high-frequency operation of the second fan 22 achieves rapid heating.

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