[0027] See also Figure 1 , Figure 1 1 is a flow chart of a clothes drying control method provided by an embodiment of the present invention. The clothes drying control method is described in detail below. Figure 1As shown, the method includes the following steps S110-S120.

[0028] S110: If a clothes drying instruction is received, the dehumidifier is controlled to enter a clothes drying mode, and the state of the clothes is determined by the image acquisition device.

[0029] In an embodiment of the present invention, when a user clicks the drying button on the dehumidifier or the drying button on the remote control that can control the dehumidifier, the sending of the drying instruction is triggered. That is, if the drying instruction is received, the dehumidifier is controlled to enter the drying mode and the state of the clothes is determined by the image acquisition device, wherein the state of the clothes includes the tilt angle of the clothes and the humidity of the clothes. Specifically, Figure 2 As shown, determining the state of clothing using the image acquisition device may specifically include steps S111-S112: S111, controlling the image acquisition device to mark the clothing to obtain a marking point, and calculating the clothing tilt angle based on the marking point and the distance between the marking point and a predetermined fixed position; S112, representing the clothing humidity by the ratio of the return light intensity to the emitted light intensity captured by the image acquisition device. It should be noted that in this embodiment, the dehumidifier is equipped with a compressor, a blower, a blower, and an image acquisition device, wherein the image acquisition device is an infrared camera; understandably, in other embodiments, the image acquisition device may be another device that only needs to be able to determine the state of clothing.

[0030] Furthermore, step S111 is specifically as follows: after the dehumidifier enters the clothes drying mode, the image acquisition device is controlled to mark a certain point on the clothes (in this application, the center point of the clothes) as a marking point by emitting infrared, and the distance L between the marking point and the preset fixed point is measured, wherein the preset fixed point refers to the contact position between the clothes hanger and the clothes drying rod. As the clothes are dried, the clothes gradually tilt and the marking point of the clothes begins to move. At this time, the image acquisition device records the moving distance d of the marking point at a frequency of 1s / time. It can be understood that the calculation process of the moving distance d is as follows: first, the distance I1=c*t from the infrared ray to the marking point in the initial state is recorded, wherein c is the propagation speed of the infrared ray and t is the time to reach the marking point. Then, the distance I2=c*t from the infrared ray to the marking point in the current state is recorded. The angle Φ between the two infrared ray emissions is known (the image acquisition device can record the angle between the two infrared ray emissions). The moving distance d can be calculated according to the cosine theorem. The moving distance d is shown in formula (1):

[0031]

[0032] The moving distance d is calculated, and the clothing tilt angle can be calculated according to the moving distance d and the distance L between the mark point and the preset fixed position. Assuming that the clothing tilt angle is A, A is as shown in formula (2):

[0033]

[0034] It should be noted that, in this embodiment, the inclination state A of the clothes mainly affects the windward area of ​​the clothes. When the clothes are in a normal relationship with the air outlet domain, the windward area of ​​the clothes is the largest. However, under normal circumstances, if the clothes want to reach the normal position, their inclination angle will be too large. At this time, the clothes will be in a relatively dangerous situation and there is a risk of falling. Therefore, the maximum inclination angle of the clothes is set to α to ensure that the clothes are in a safe drying position. For drying, the initial state of the clothes is recorded by the image acquisition device, and the inclination state of the clothes is continuously recorded at intervals of 1 second and the air volume is gradually increased or decreased at a speed of 1r / s until the inclination angle A of the clothes is equal to α. Thereafter, the inclination angle A of the clothes is recorded every 30 seconds to ensure that the value of the inclination angle A of the clothes is within the range of α±0.5° to better dry the clothes.

[0035] Furthermore, step S112 is specifically as follows: for a wet piece of clothing, its physical properties will vary due to different water content. For a dry piece of clothing, the surface is rough. When the clothing is soaked, the rough surface of the clothing is filled with water and the entire surface is approximately smooth (i.e., a water surface). On the smooth surface and the rough surface of the clothing, when light contacts the clothing, it will first be absorbed and then reflected. When it contacts the water layer again, part of the light is refracted and the other part is reflected back. The light intensity absorption X of the wet clothing can be expressed by formula (3):

[0036] X=I 光 (1-α w )[β y +β y (1-β y )α w +…] (3)

[0037] In formula (3), α w is the reflectivity of the water surface, β y is the absorption rate of the clothing surface, I 光 is the light intensity. From formula (3), we can know that the light absorption intensity of wet clothes, as the humidity of clothes decreases, the water film surface gradually decreases, the number of times light is reflected in the water layer decreases, the number of times clothes absorb light decreases, the overall light intensity absorption decreases, and the return light intensity gradually increases. Assume I 回 To return the light intensity, I 出 is the emitted light intensity, I is the relative light intensity, and I is as shown in formula (4):

[0038]

[0039] It should be noted that in this embodiment, by emitting infrared rays to wet clothes, the humidity B of the clothes is judged according to the ratio between the emitted light intensity and the returned light intensity. The emitted light intensity and the returned light intensity can be converted into electrical signals or temperature signals for comparison. When the ratio I remains constant or fluctuates within a certain range, it can be determined at this time that the clothes are dry. However, in order to prevent some areas from still being in a wet state, it is set that the dehumidifier first turns off the compressor, and then the fan continues to run for 3 minutes before turning off, so as to ensure the drying effect of the clothes.

[0040] S120. Obtain the ambient temperature, and adjust the frequency of the compressor and the rotation speed of the fan according to the state of the clothes and the ambient temperature, so as to control the air volume and the air outlet temperature of the dehumidifier in the drying mode.

[0041] In the embodiment of the present invention, after determining the state of the clothes through the image acquisition device, the ambient temperature can be obtained through the sensor, and the frequency of the compressor and the rotation speed of the fan are adjusted according to the state of the clothes and the ambient temperature. Specifically, as Figure 3 shown, step S120 may specifically include steps S121 - S123: S121. If the ambient temperature is greater than the first preset ambient temperature, adjust the frequency of the compressor and the rotation speed of the fan according to the inclination angle of the clothes and the humidity of the clothes through the first drying adjustment method; S122. If the ambient temperature is greater than the second preset ambient temperature and less than or equal to the first preset ambient temperature, adjust the frequency of the compressor and the rotation speed of the fan according to the inclination angle of the clothes and the humidity of the clothes through the second drying adjustment method; S123. If the ambient temperature is less than or equal to the second preset ambient temperature, adjust the frequency of the compressor and the rotation speed of the fan according to the inclination angle of the clothes and the humidity of the clothes through the third drying adjustment method. It can be understood that after adjusting the frequency of the compressor and the rotation speed of the fan, the air volume and the air outlet temperature of the dehumidifier in the drying mode can be controlled. It should be noted that in this embodiment, the first preset ambient temperature is 35°, and the second preset ambient temperature is 20°. Assuming the ambient temperature is T0, that is, T0 > 35°, the frequency of the compressor and the rotation speed of the fan are adjusted by the first drying adjustment method; 20° < T0 ≤ 35°, the frequency of the compressor and the rotation speed of the fan are adjusted by the second drying adjustment method; T0 ≤ 20°, the frequency of the compressor and the rotation speed of the fan are adjusted by the third drying adjustment method. It should be noted that in other embodiments, the first preset ambient temperature and the second preset ambient temperature can also be set to other temperature values, which are set according to actual needs and are not specifically limited here.

[0042] Furthermore, the frequency of the compressor and the speed of the fan are adjusted according to the clothing inclination angle and the clothing humidity through the first drying adjustment method / the second drying adjustment method / the third drying adjustment method, including: judging whether the clothing inclination angle is equal to the preset clothing inclination angle; if the clothing inclination angle is not equal to the preset clothing inclination angle, adjusting the speed of the fan, and controlling the compressor to operate at the minimum frequency / maximum frequency / rated frequency, and returning to execute the step of judging whether the clothing inclination angle is equal to the preset clothing inclination angle; if the clothing inclination angle is equal to the preset clothing inclination angle, controlling the compressor to operate at the minimum frequency / maximum frequency / rated frequency, and keeping the speed of the fan unchanged; adjusting the frequency of the compressor and the speed of the fan according to the clothing humidity. It should be noted that in this embodiment, if the clothing tilt angle is not equal to the preset clothing tilt angle, then adjusting the fan speed includes: determining whether the clothing tilt angle is greater than the preset clothing tilt angle; if so, reducing the fan speed; if not, increasing the fan speed. It should also be noted that in this embodiment, the preset clothing tilt angle is α; adjusting the fan speed can affect the air output volume in the drying mode, and adjusting the compressor frequency can affect the air output temperature in the drying mode.

[0043] Furthermore, the frequency of the compressor and the speed of the fan are adjusted according to the humidity of the clothes, including: if the current operating frequency of the compressor is the minimum frequency / the maximum frequency, indicating that the first drying adjustment method / the third drying adjustment method is used to adjust the frequency of the compressor and the speed of the fan, then it is determined whether the relative light intensity ratio corresponding to the humidity of the clothes is a first preset light intensity ratio; if the relative light intensity ratio corresponding to the humidity of the clothes is the first preset light intensity ratio, the frequency of the compressor is adjusted to a preset stop frequency to stop the compressor, and the speed of the fan is controlled to be adjusted to a preset stop speed after running for a preset running time to stop the fan: understandably, if the relative light intensity ratio corresponding to the humidity of the clothes is not the first preset light intensity ratio, the compressor is controlled to run at the minimum frequency / maximum frequency, and the speed of the fan is kept unchanged. It should be noted that, in this embodiment, the first preset light intensity ratio is C, and C can be set according to actual needs; the preset running time is 3 minutes, and in other embodiments, the preset running time can also be set to other values.

[0044] Furthermore, adjusting the compressor frequency and fan speed based on the laundry humidity includes: if the current operating frequency of the compressor is the rated frequency, indicating that the second laundry drying adjustment method is being used to adjust the compressor frequency and fan speed, determining whether the relative light intensity ratio corresponding to the laundry humidity is greater than a second preset light intensity ratio; if the relative light intensity ratio corresponding to the laundry humidity is not greater than the second preset light intensity ratio, increasing the compressor frequency and increasing the fan speed; if the relative light intensity ratio corresponding to the laundry humidity is greater than the second preset light intensity ratio, decreasing the compressor frequency and decreasing the fan speed, and executing the step of determining whether the relative light intensity ratio corresponding to the laundry humidity is the first preset light intensity ratio. It should be noted that in this embodiment, the second preset light intensity ratio is 50%. In other embodiments, the second preset light intensity ratio can be set according to actual needs. It is understandable that the second preset light intensity ratio is less than the first preset light intensity ratio. It should also be noted that, in this embodiment, a larger relative light intensity ratio indicates that the clothes are drier.

[0045] It should be noted that in this embodiment, the ambient temperature, clothing tilt angle A, and clothing humidity B are combined to control the drying function, thereby jointly controlling the dehumidifier's outlet air temperature, air volume, and the start and stop of the drying process. The dehumidifier uses a sensor to monitor the ambient temperature every 60 seconds. When the ambient temperature T0 is greater than 35°C, the dehumidifier compressor operates at its lowest frequency, heating the outlet air based on the ambient temperature to dry the clothes. When the ambient temperature is 20°C less than T0 and less than 35°C, the dehumidifier compressor operates normally and automatically adjusts the compressor frequency and, in turn, the outlet air temperature based on the clothing humidity range. Depending on the clothing humidity range, the compressor frequency is increased or decreased to control the outlet air temperature. Higher clothing humidity increases the compressor frequency and, consequently, the outlet air temperature, thereby drying the clothes. When the ambient temperature T0 is less than 20°C, the dehumidifier forces the compressor to operate at the highest frequency within its permitted range, ensuring the highest outlet air temperature for drying the clothes. In other embodiments, the ambient air volume can also be incorporated into the clothing tilt state A to control the dehumidifier's outlet air volume.

[0046] Figure 4 A simplified flow chart of a clothes drying control process using a first clothes drying adjustment method provided in an embodiment of the present invention is shown in FIG. Figure 4As shown in the figure, the first step: the dehumidifier enters the drying mode, and determines the clothing tilt angle A and the clothing humidity B through the image acquisition device. The second step: detect the ambient temperature T0, and determine whether T0 is greater than 35°C; if T0 > 35°C, then execute the third step. The third step: compare A with the set value α. When A = α, execute the fourth step. When A > α, execute the fifth step. When A < α, execute the sixth step. The fourth step: the compressor runs at the lowest frequency, and keeps the fan speed unchanged, that is, keeps the current air output running, and execute the seventh step. The fifth step: the compressor runs at the lowest frequency, reduces the fan speed by 1 r / s to reduce the current air output, and execute the third step. The sixth step: the compressor runs at a low frequency, increases the fan speed by 1 r / s to increase the current air output, and execute the third step. The seventh step: after keeping the dehumidifier running for H minutes, determine whether I is equal to C. If I = C, then execute the eighth step, otherwise execute the seventh step. The eighth step: the compressor stops running, and the fan continues to run for 3 minutes and then stops, ending the drying process.

[0047] Figure 5 This is a flowchart of the drying control by the second drying adjustment method provided by the embodiment of the present invention. As Figure 5 As shown in the figure, the first step: the dehumidifier enters the drying mode, and determines the clothing tilt angle A and the clothing humidity B through the image acquisition device. The second step: detect the ambient temperature T0, and determine whether T0 satisfies 20° < T0 ≤ 35°C; if it is satisfied, then execute the third step. The third step: compare A with the set value α. When A = α, execute the fourth step. When A > α, execute the fifth step. When A < α, execute the sixth step. The fourth step: the compressor runs at the rated frequency, and keeps the fan speed unchanged, that is, keeps the current air output running, and execute the seventh step. The fifth step: the compressor runs at the rated frequency, reduces the fan speed by 1 r / s to reduce the current air output, and execute the third step. The sixth step: the compressor runs at the rated frequency, increases the fan speed by 1 r / s to increase the current air output, and execute the third step. The seventh step: after keeping the dehumidifier running for H minutes, determine whether I is greater than 50%; if I > 50%, then execute the eighth step, otherwise execute the ninth step. The eighth step: run at the current air output, increase the frequency of the compressor, and increase the air outlet temperature, and execute the seventh step. The ninth step: run at the current air output, reduce the frequency of the compressor, and reduce the air outlet temperature, and execute the tenth step. The tenth step: after keeping the dehumidifier running for H minutes, determine whether it satisfies I = C. If it is satisfied, then execute the eleventh step, otherwise execute the tenth step. The eleventh step: the compressor stops running, and the fan continues to run for 3 minutes and then stops, ending the drying process.

[0048] Figure 6 This is a flowchart of the drying control by the third drying adjustment method provided by the embodiment of the present invention. As Figure 6As shown, the first step is to enter the dehumidifier's drying mode and determine the clothing tilt angle A and clothing humidity B using an image acquisition device. The second step is to detect the ambient temperature T0 and determine whether it is less than or equal to 20°C. If T0 ≤ 20°C, proceed to step 3. The third step is to compare A with the set value α. If A = α, proceed to step 4; if A > α, proceed to step 5; and if A < α, proceed to step 6. The fourth step is to operate the compressor at its highest frequency, maintaining the fan speed constant, i.e., maintaining the current air output. The seventh step is to execute. The fifth step is to operate the compressor at its highest frequency, reducing the fan speed by 1 rpm to reduce the current air output. The third step is to execute. The sixth step is to operate the compressor at a high frequency, increasing the fan speed by 1 rpm to increase the current air output. The third step is to execute. The seventh step is to maintain the dehumidifier's operation for H minutes and determine whether I equals C. If I = C, proceed to step 8; otherwise, proceed to step 7. The eighth step is to shut down the compressor and the fan, which continues to run for 3 minutes, ends the drying process.

[0049] To sum up, the inclination angle of the clothes and the humidity of the clothes are determined by the image acquisition device, and the frequency of the compressor and the speed of the fan are adjusted at different stages of the drying process according to the ambient temperature, the inclination angle of the clothes and the humidity of the clothes, so as to control the air volume and the air temperature of the dehumidifier in the drying mode in real time, making the drying more intelligent and reasonable, not only improving the drying efficiency and saving energy, but also having a better drying effect.
