[0048] At present, there are two main heating methods used in dryers on the market, namely electric heating using electric heating wires or electric heating tubes and heat pump heating using heat pump compressors. Both methods heat the air first, then let the heated air flow through the clothes to be dried, and take away the moisture on the clothes through the dry and hot air, thereby achieving the effect of drying clothes. Among them, the electric heating dryer converts electrical energy into thermal energy to achieve air heating, but this method consumes a lot of power, the hot air temperature is high, and there is a problem of uneven heating, which is easy to damage the fibers of the clothes to be dried. The heat pump dryer uses the principle of heat pump to heat the internal circulating air, but its drying efficiency is low, the drying time is long, and there is also a problem of uneven drying. Related technology proposes a radio frequency dryer, which is provided with a radio frequency module. The clothes are heated by microwaves, so that the drying time can be shortened and the drying effect can be improved.
[0049] However, the moisture in the clothes to be dried will gradually concentrate to the lower part of the clothes due to the influence of gravity, making the lower part of the clothes to be dried more difficult to be dried.
[0050] Combination Figure 1-5 As shown, an embodiment of the present disclosure provides a clothes dryer, including: a shell 1, a clothes drying box 2, a radio frequency module 3 and a heat pump module 4. The shell 1 has an internal structure with a accommodating cavity 11. The clothes drying box 2 is arranged in the accommodating cavity 11, and has an internal structure with a clothes drying chamber 21. The clothes drying box 2 is provided with an air inlet 23 and an air outlet 22 to connect the accommodating cavity 11 with the clothes drying chamber 21. The heat pump module 4 is arranged in the accommodating cavity 11, and is used to heat the air transported to the clothes drying chamber 21. The radio frequency module 3 is arranged in the accommodating cavity 11, and the radio frequency module 3 includes a magnetron 31 and a waveguide slot antenna array 32. The magnetron 31 is arranged in the accommodating cavity 11 below the clothes drying box 2, and the waveguide slot antenna array 32 is arranged on the side wall of the clothes drying box 2. The magnetron 31 is connected to the input end of the waveguide slot antenna array 32.
[0051] The clothes dryer provided by the embodiment of the present disclosure operates the heat pump module 4 to heat the air delivered to the drying chamber 21, and the hot dry air entering the drying chamber 21 can take away the moisture on the clothes to achieve the effect of drying the clothes. At the same time, the embodiment of the present disclosure also operates the radio frequency module 3 to radiate electromagnetic waves into the drying chamber 21, so that the moisture in the clothes to be dried can be quickly heated, which is beneficial to shorten the drying time of the clothes and improve the drying effect. In addition, the embodiment of the present disclosure adopts the radio frequency structure of the magnetron 31 and the waveguide slot antenna array 32, which can reasonably decompose the electromagnetic wave energy generated by the magnetron 31 to achieve the dispersed radiation of the electromagnetic waves, which is beneficial to avoid the situation where the electromagnetic waves in the drying chamber 21 are locally accumulated and cause damage to the clothes. In addition, the magnetron 31 is arranged below the clothes drying box 2 and is connected to the input end of the waveguide slot antenna array 32 arranged on the side wall of the clothes drying box 2. Since the waveguide slot antenna array 32 can radiate more electromagnetic waves on the side close to the input end than on the side far from the input end, the waveguide slot antenna array 32 in the embodiment of the present disclosure generates a greater electromagnetic field strength in the lower part of the drying chamber 21, thereby effectively improving the drying effect of the lower part of the clothes where moisture is more concentrated due to gravity. Therefore, by arranging the magnetron 31 below the drying box 2 and transmitting electromagnetic wave energy from bottom to top, the embodiment of the present disclosure can achieve mutual adaptation between uneven electromagnetic wave radiation and uneven moisture distribution of the clothes to be dried, which is conducive to improving the uniformity of clothes drying.
[0052] The basic principle of drying clothes by the radio frequency module 3 is: for the clothes to be dried, the water molecules in the water contained therein are polar molecules, while the cloth or its decorations are non-polar molecules. Polar molecules such as water molecules will change their arrangement direction with the direction of the electric field in the electric field. When the direction of the electric field changes, the arrangement direction of the water molecules will also change accordingly. Therefore, when polar molecules such as water molecules are in an alternating electric field, the arrangement direction of their molecules will rapidly flip with the electric field, thereby generating friction. The friction of the molecules causes heat generation, thereby realizing the rapid heating of the water, converting it from liquid to gas, thereby achieving the effect of drying clothes.
[0053] The basic principle of drying clothes by the heat pump module 4 is: using the heat pump principle to heat the internal circulating air, and using the dry hot air flow to heat the moisture in the clothes to be dried, so that the liquid water in the clothes to be dried is converted into water vapor, and then the dry hot air flow is used to take the water vapor away, thereby achieving the effect of drying the clothes.
[0054] It can be understood that the magnetron 31 is arranged in the accommodating cavity 11 below the drying box 2. Therefore, in order to realize the connection between the input end of the waveguide slot antenna array 32 and the magnetron 31, the input end of the waveguide slot antenna array 32 must be located below the dryer, so that the electromagnetic field intensity generated by the waveguide slot antenna array 32 in the lower part of the drying cavity 21 is stronger, so as to improve the drying effect on the lower part of the clothes where the moisture is more concentrated due to gravity.
[0055] Optionally, the input end of the waveguide slot antenna array 32 is located at a position corresponding to the lower part of the drying chamber 21. In this way, it can ensure that the electromagnetic wave energy is transmitted from bottom to top, so as to achieve mutual adaptation between uneven electromagnetic wave radiation and uneven moisture distribution of the clothes to be dried, which is conducive to improving the uniformity of clothes drying.
[0056] Optionally, the waveguide slot antenna array 32 includes a first waveguide slot antenna array 321 and a second waveguide slot antenna array 322, the first waveguide slot antenna array 321 is arranged on the first side wall of the clothes drying box 2, the second waveguide slot antenna array 322 is arranged on the second side wall of the clothes drying box 2, and the first waveguide slot antenna array 321 and the second waveguide slot antenna array 322 are symmetrically arranged. In this way, the embodiment of the present disclosure can make the electromagnetic waves in the clothes drying chamber 21 relatively evenly distributed by symmetrically arranging the first waveguide slot antenna array 321 and the second waveguide slot antenna array 322 on both sides of the clothes drying box 2, thereby improving the uneven heating phenomenon in the horizontal direction caused by the attenuation of the electromagnetic waves in the clothes drying chamber 21, which is conducive to improving the uniformity of clothes drying.
[0057] Optionally, the first waveguide slot antenna array 321 includes multiple columns of waveguide slot antennas 323 extending vertically upward, and the second waveguide slot antenna array 322 includes multiple columns of waveguide slot antennas 323 extending vertically upward. In this way, by providing multiple columns of waveguide slot antennas 323 extending vertically upward, the high-energy electromagnetic waves emitted by the magnetron 31 can be decomposed into multiple small beams with limited energy, so that they can be uniformly radiated into the drying chamber 21 in the horizontal direction. Therefore, the embodiment of the present disclosure can not only uniformly heat the moisture in the clothes to be dried, but also prevent the formation of local hot spots on the clothes to be dried, thereby improving the drying efficiency of the whole machine without causing damage to the clothes to be dried.
[0058] Optionally, the waveguide slot antennas 323 are n columns, 2≤n≤10, and n is a positive integer. Among them, the first waveguide slot antenna array 321 includes n1 columns of waveguide slot antennas 323, and the second waveguide slot antenna array 322 includes n2 columns of waveguide slot antennas 323, n1+n2=n. In this way, by determining the values of n1 and n2, the embodiment of the present disclosure can reasonably adjust the electromagnetic wave distribution on both sides of the drying chamber 21, so as to improve the uniformity of clothing drying.
[0059] Optionally, n=8, n1=n2=4. In this way, the waveguide slot antennas 323 on the first waveguide slot antenna array 321 and the waveguide slot antennas 323 on the second waveguide slot antenna array 322 are symmetrically arranged, so that the electromagnetic waves in the drying chamber 21 can be relatively evenly distributed, which can improve the uneven heating phenomenon in the horizontal direction caused by the attenuation of electromagnetic waves in the drying chamber 21, and is beneficial to improving the uniformity of clothing drying. And when the number of columns of the waveguide slot antennas 323 exceeds 4 columns, the effect of improving the heating uniformity is small. Therefore, the embodiment of the present disclosure arranges 4 waveguide slot antennas 323 on both sides of the drying chamber 21, which is beneficial to take into account both the drying effect and the installation cost.
[0060] Optionally, each waveguide slot antenna 323 is provided with a plurality of vertically distributed waveguide slots 324. Thus, by providing a plurality of vertically distributed waveguide slots 324, the electromagnetic wave energy transmitted to the waveguide slot antenna 323 can be decomposed again and dispersedly radiated into the clothes drying chamber 21 through the plurality of waveguide slots 324. The electromagnetic wave energy radiated from each waveguide slot 324 is only a small part of the total energy generated by the magnetron 31, so the embodiment of the present disclosure can achieve dispersed radiation of electromagnetic waves and avoid the phenomenon of localized large accumulation of electromagnetic wave energy.
[0061] Optionally, the spacing d between adjacent waveguide slots 324 is greater than or equal to the vacuum wavelength of the electromagnetic wave. In this way, by controlling the spacing between adjacent waveguide slots 324, the disclosed embodiment can form multiple side lobes, so that the electromagnetic wave beam is evenly distributed in the drying chamber 21, so as to relatively evenly heat the moisture in the clothes to be dried, while avoiding the formation of local hot spots and thus damaging the clothes.
[0062] Optionally, the vacuum wavelength of the electromagnetic wave refers to the wavelength of the electromagnetic wave with a center frequency of 2450 MHz in a vacuum. In this way, it is beneficial to radiate the multiple electromagnetic wave beams formed by the waveguide slot antenna array 32 into the clothes drying chamber 21 in a dispersed manner.
[0063] Optionally, the magnetron 31 includes a first magnetron 311 and a second magnetron 312, the first magnetron 311 is connected to the input end of the first waveguide slot antenna array 321, and the second magnetron 312 is connected to the input end of the second waveguide slot antenna array 322. In this way, considering the actual application scenario, the clothes to be dried hung on the left and right sides of the drying chamber 21 may have large differences due to their respective sizes, weights, materials, humidity, quantities and other information. At this time, even if the electromagnetic field distribution in the drying chamber 21 is uniform, the clothes to be dried at different positions may be unevenly dried. The embodiment of the present disclosure sets the first magnetron 311 and the second magnetron 312, and respectively connects the first waveguide slot antenna array 321 and the second waveguide slot antenna array 322 arranged on both sides of the drying box 2, so as to form two sets of relatively independent radio frequency systems. Therefore, the embodiment of the present disclosure can respectively monitor the clothing information on the left side of the drying chamber 21 and the clothing information on the right side of the drying chamber 21, and can specifically adjust the working parameters of the corresponding magnetrons 31 to more reasonably set the electromagnetic field strength on the side where the clothes are located, thereby fully utilizing the advantages of the electromagnetic wave heating method and facilitating improving the uniformity of clothing drying.
[0064] Optionally, the embodiment of the present disclosure may also only have one magnetron 31, which is connected to the first waveguide slot antenna array 321 and the second waveguide slot antenna array 322 at the same time, so as to simultaneously transmit electromagnetic wave energy to the first waveguide slot antenna array 321 and the second waveguide slot antenna array 322. The embodiment of the present disclosure does not specifically limit the number of magnetrons 31. In this way, the installation cost of the RF module 3 can be further reduced.
[0065] Optionally, the RF module 3 further includes a frequency converter 33, which is electrically connected to the magnetron 31 and is used to adjust the working parameters of the magnetron 31. In this way, the embodiment of the present disclosure can control the magnetron 31 through the frequency converter 33, so that the magnetron 31 outputs continuous electromagnetic waves, and its output power is continuously adjustable.
[0066] Optionally, the frequency converter 33 includes a first frequency converter 331 and a second frequency converter 332. The first frequency converter 331 is electrically connected to the first magnetron 311, and is used to adjust the working parameters of the first magnetron 311. The second frequency converter 332 is electrically connected to the second magnetron 312, and is used to adjust the working parameters of the second magnetron 312. The embodiment of the present disclosure does not specifically limit the number of frequency converters 33. Preferably, the number of frequency converters 33 matches the number of magnetrons 31. In this way, the embodiment of the present disclosure can control the working parameters of the first magnetron 311 and the second magnetron 312 respectively through the first frequency converter 331 and the second frequency converter 332, so as to more reasonably set the electromagnetic field strength on the side where the clothes are located, so as to give full play to the advantages of the electromagnetic wave heating method, which is conducive to improving the uniformity of drying clothes. In addition, the disclosed embodiment can also adjust the switching frequency of the magnetron 31 according to the control algorithm of the inverter 33, thereby effectively reducing the excessively rapid temperature rise in the local area of the drying chamber 21 and achieving a balance between temperature rise and heat conduction, which is also beneficial to improving the uniformity of clothing drying.
[0067] Optionally, the RF module 3 further includes a waveguide power divider, which is used to connect the magnetron 31 and the waveguide slot antenna array 32 to evenly divide the electromagnetic wave energy transmitted to the waveguide slot antenna array 32. In this way, the embodiment of the present disclosure can evenly divide the electromagnetic wave energy output by the magnetron 31 through the waveguide power divider, and transmit each evenly divided portion of the electromagnetic wave energy to the multiple columns of waveguide slot antennas 323. Therefore, the embodiment of the present disclosure can achieve dispersed radiation of electromagnetic waves and avoid the phenomenon of localized large accumulation of electromagnetic wave energy.
[0068] Optionally, the waveguide power divider includes a first waveguide power divider and a second waveguide power divider. The first waveguide power divider is used to connect the first magnetron 311 and the first waveguide slot antenna array 321 to evenly divide the electromagnetic wave energy transmitted to the first waveguide slot antenna array 321. The second waveguide power divider is used to connect the second magnetron 312 and the second waveguide slot antenna array 322 to evenly divide the electromagnetic wave energy transmitted to the second waveguide slot antenna array 322. The embodiment of the present disclosure does not specifically limit the number of waveguide power dividers. Preferably, the number of waveguide power dividers is adapted to the number of waveguide slot antenna arrays 32. In the embodiment of the present disclosure, the first waveguide power divider and the second waveguide power divider are both one-to-four waveguide power dividers. In this way, through the first waveguide power divider, the embodiment of the present disclosure can divide the electromagnetic wave energy output by the first magnetron 311 into four parts, so that they flow into the four waveguide slot antennas 323 on the first waveguide slot antenna array 321 respectively, so that the electromagnetic wave energy can be dispersed and radiated to the corresponding sides in the drying chamber 21. Similarly, through the second waveguide power divider, the embodiment of the present disclosure can divide the electromagnetic wave energy output by the second magnetron 312 into four parts, so that they flow into the four waveguide slot antennas 323 on the second waveguide slot antenna array 322 respectively, so that the electromagnetic wave energy can be dispersed and radiated to the corresponding sides in the drying chamber 21. Therefore, the embodiment of the present disclosure can achieve dispersed radiation of electromagnetic waves and avoid the phenomenon of local large-scale accumulation of electromagnetic wave energy.
[0069] Optionally, the waveguide power divider is integrally formed with the waveguide slot antenna array 32. The first waveguide power divider is integrally formed with the first waveguide slot antenna array 321, and the second waveguide power divider is integrally formed with the second waveguide slot antenna array 322. In this way, through the integrated design of the waveguide power divider and the waveguide slot antenna array 32, the structure of the RF module 3 is relatively simple, which is conducive to reducing the installation cost.
[0070] Optionally, the clothes drying box 2 includes a bottom wall, a top wall, a first side wall, a second side wall and a back wall, and the bottom wall, the top wall, the first side wall, the second side wall and the back wall enclose and define a clothes drying chamber 21. The bottom wall is arranged opposite to the top wall, the bottom wall is located at the bottom of the clothes drying box 2, and the top wall is located at the top of the clothes drying box 2. The first side wall and the second side wall are arranged opposite to each other, and the first side wall and the second side wall are located at the left and right sides of the clothes drying box 2, respectively.
[0071] Optionally, the bottom wall of the drying box 2 and the shell 1 construct a first accommodating chamber 111, the top wall of the drying box 2 and the shell 1 construct a second accommodating chamber 112, the first side wall of the drying box 2 and the shell 1 construct a first air duct 113, the second side wall of the drying box 2 and the shell 1 construct a second air duct 114, and the back wall of the drying box 2 and the shell 1 construct a third air duct 115.

In this way, the airflow in the first air duct 113 can be used to dissipate heat for the first waveguide slot antenna array 321, and the airflow in the second air duct 114 can be used to dissipate heat for the second waveguide slot antenna array 322. Therefore, the embodiment of the present disclosure can recycle the waste heat generated by the first waveguide slot antenna array 321 and the second waveguide slot antenna array 322, which is conducive to improving the energy efficiency of the whole machine.
[0073] Optionally, the first waveguide slot antenna array 321 is integrally formed with the first side wall of the clothes drying box 2, and the second waveguide slot antenna array 322 is integrally formed with the second side wall of the clothes drying box 2. In this way, the integrated design of the side wall of the clothes drying box 2 and the waveguide slot antenna array 32 is conducive to better radiation of electromagnetic waves into the clothes drying chamber 21.
[0074] Optionally, the waveguide slots 324 on the first waveguide slot antenna array 321 are opened on the first side wall of the clothes drying box 2, and the waveguide slots 324 on the second waveguide slot antenna array 322 are opened on the second side wall of the clothes drying box 2. In this way, the embodiment of the present disclosure can be designed with openings on the first side wall and the second side wall of the clothes drying box 2, so as to form a plurality of waveguide slots 324, which is conducive to more uniformly radiating electromagnetic waves into the clothes drying chamber 21.

The first magnetron 311 is arranged in the first accommodating cavity 111 near the first waveguide slot antenna array 321, and the second magnetron 312 is arranged in the first accommodating cavity 111 near the second waveguide slot antenna array 322. In this way, by arranging the first magnetron 311 and the second magnetron 312 in the first accommodating cavity 111 below the clothes drying box 2, the embodiment of the present disclosure can make the input end of the first waveguide slot antenna array 321 and the input end of the second waveguide slot antenna array 322 both located at the lower part of the clothes drying machine, so that the waveguide slot antenna 323 can transmit electromagnetic wave energy from bottom to top. Since the side of the waveguide slot antenna 323 close to the input end can radiate more electromagnetic waves than the side far from the input end, the electromagnetic field intensity generated by the waveguide slot antenna array 32 in the embodiment of the present disclosure at the lower part of the clothes drying chamber 21 is greater, thereby effectively improving the drying effect of the lower part of the clothes where the moisture is more concentrated due to gravity. Therefore, by arranging the magnetron 31 in the first accommodating cavity 111 below the clothes drying box 2, the embodiment of the present disclosure can achieve mutual adaptation between uneven electromagnetic wave radiation and uneven moisture distribution of the clothes to be dried, which is beneficial to improving the uniformity of clothes drying.

Since the first waveguide slot antenna array 321 and the second waveguide slot antenna array 322 are respectively provided on both sides of the clothes drying box 2, the electromagnetic field strength is greater at the position closer to the waveguide slot 324 inside the clothes drying chamber 21, and the corresponding clothes drying effect is more obvious, so the clothes on the left and right sides of the clothes drying chamber 21 are easier to be dried. As the electromagnetic wave penetrates the clothes and the transmission distance increases, the electromagnetic wave energy will gradually attenuate, resulting in a poor drying effect for the clothes in the middle of the clothes drying chamber 21.

In this way, the embodiment of the present disclosure enables the air inside the clothes drying chamber 21 to be discharged more evenly, so as to avoid the accumulation of hot and humid air on both sides of the clothes drying chamber 21, thereby facilitating the uniformity of clothes drying.
[0093] Optionally, the clothes dryer further includes a humidity sensor 6, which is disposed at the lower part of the clothes drying chamber 21 and is used to detect the humidity of the air flowing through the clothes.

Thus, the operation of the RF module 3 and the heat pump module 4 can be controlled accordingly to take into account the uniformity and reliability of clothes drying.
[0094] Optionally, the humidity sensor 6 includes a first humidity sensor 61, a second humidity sensor 62 and a third humidity sensor 63.

[0097] Optionally, the door body 12 is provided with a shielding rubber strip, so that electromagnetic waves can be prevented from leaking out, which is beneficial to improving user safety.
[0098] Based on the above dryer, combined Figure 6As shown, the embodiment of the present disclosure provides a control method for a clothes dryer, comprising:
[0099] S101, the processor controls the humidity sensor to detect air humidity.
[0100] S102, the processor adjusts the working parameters of the magnetron according to the air humidity to transmit electromagnetic wave energy to the waveguide slot antenna array.
[0101] By adopting the control method for a clothes dryer provided by the embodiment of the present disclosure, the RF module is operated to radiate electromagnetic waves into the drying chamber, so that the moisture in the clothes to be dried can be quickly heated, which is conducive to shortening the drying time of the clothes and improving the drying effect. In addition, the embodiment of the present disclosure adopts the RF structure of the magnetron and the waveguide slot antenna array, which can reasonably decompose the electromagnetic wave energy generated by the magnetron to achieve the dispersed radiation of the electromagnetic wave, which is conducive to avoiding the situation where the electromagnetic wave is locally accumulated in the drying chamber and causes the clothes to be damaged. In addition, the embodiment of the present disclosure also detects the humidity of the air flowing through the clothes through the humidity sensor provided at the lower part of the drying chamber to determine the water content of the clothes to be dried, and adjusts the working parameters of the magnetron accordingly, so that the electromagnetic field strength in the drying chamber can be reasonably set, which is conducive to giving full play to the advantages of the electromagnetic wave heating method. In addition, the embodiment of the present disclosure can timely adjust the RF module amplifier when the water content of the clothes to be dried decreases, so as to effectively avoid the situation where the clothes are locally overheated or electromagnetic ignited inside the clothes dryer, which is conducive to improving the reliability of clothes drying.
[0102] Optionally, the processor adjusts the working parameters of the magnetron according to the air humidity, including: when the air humidity is greater than or equal to the first humidity threshold, the processor controls the magnetron to operate at the first power; or, when the air humidity is less than the first humidity threshold and greater than or equal to the second humidity threshold, the processor controls the magnetron to operate at the second power; or, when the air humidity is less than the second humidity threshold and greater than or equal to the third humidity threshold, the processor controls the magnetron to operate at the third power. Wherein, the first humidity threshold is greater than the second humidity threshold, the second humidity threshold is greater than the third humidity threshold, the first power is greater than the second power, and the second power is greater than the third power. In this way, the embodiment of the present disclosure can judge the moisture content of the clothes in the drying chamber by comparing the detected air humidity with the size relationship of multiple preset humidity thresholds. When the air humidity is greater than or equal to the first humidity threshold, it indicates that the air humidity flowing through the clothes in the drying chamber is too high, and the moisture content of the clothes is extremely high. Therefore, the embodiment of the present disclosure controls the magnetron to operate at a relatively large first power to increase the electromagnetic wave energy transmitted to the waveguide slot antenna array, thereby effectively enhancing the electromagnetic field strength in the drying chamber, which is beneficial to improving the drying effect on clothes with extremely high water content. When the air humidity is less than the first humidity threshold and greater than or equal to the second humidity threshold, it indicates that the air humidity flowing through the clothes in the drying chamber is slightly higher, and the clothes have a high water content at this time. Therefore, the embodiment of the present disclosure controls the magnetron to operate at a slightly larger second power to slightly increase the electromagnetic wave energy transmitted to the waveguide slot antenna array, thereby appropriately enhancing the electromagnetic field strength in the drying chamber, which is beneficial to improving the drying effect on clothes with a high water content. When the air humidity is less than the second humidity threshold and greater than or equal to the third humidity threshold, it indicates that the air humidity flowing through the clothes in the drying chamber is relatively low, and the clothes have a low water content at this time. Therefore, the embodiment of the present disclosure controls the magnetron to operate at a smaller third power to reduce the electromagnetic wave energy transmitted to the waveguide slot antenna array, thereby appropriately weakening the electromagnetic field strength in the drying chamber, which is beneficial to avoiding local overheating or electromagnetic ignition inside the dryer and improving the reliability of clothing drying.
[0103] Optionally, the control method for the clothes dryer further includes: when the air humidity is less than a third humidity threshold, the processor controls the magnetron to stop working. In this way, when the air humidity is less than the third humidity threshold, it indicates that the air humidity flowing through the clothes in the drying chamber is extremely low, and at this time the moisture content of the clothes on this side is extremely low, and drying has been basically achieved. Therefore, the embodiment of the present disclosure controls the magnetron to stop working, which can save electric energy while effectively avoiding the occurrence of local overheating or electromagnetic ignition inside the clothes dryer, which is conducive to improving the reliability of clothes drying.
[0104] Optionally, the first humidity threshold can be set according to clothing information. For example, the clothing information is the material of the clothing. If the material of the clothing to be dried is down material that is difficult to dry, a relatively small first humidity threshold can be set to accelerate the rapid evaporation of water in the clothing to be dried through more electromagnetic wave energy output, thereby shortening the clothing drying time and improving the drying effect. Preferably, the first humidity threshold is 80%. The first humidity threshold can also be adjusted according to the actual needs of the user, and can also be set to any other value such as 75% or 85%.
[0105] Optionally, the second humidity threshold can be set according to clothing information. For example, the clothing information is the material of the clothing. If the material of the clothing to be dried is down material that is difficult to dry, a relatively small second humidity threshold can be set to accelerate the rapid evaporation of water in the clothing to be dried through more electromagnetic wave energy output, thereby shortening the clothing drying time and improving the drying effect. Preferably, the second humidity threshold is 60%. The second humidity threshold can also be adjusted according to the actual needs of the user, and can also be set to any other value such as 55% or 65%.
[0106] Optionally, the third humidity threshold can be set according to clothing information. Exemplarily, the clothing information is the material of the clothing. If the material of the clothing to be dried is a polyester-cotton material that is less difficult to dry, a relatively large third humidity threshold can be set to shut down the radio frequency module more promptly, thereby helping to avoid local overheating or electromagnetic ignition inside the dryer, and helping to improve the reliability of clothing drying. Preferably, the third humidity threshold is 40%. The third humidity threshold can also be adjusted according to the actual needs of the user, and can also be set to any other value such as 35% or 45%.
[0107] Optionally, the first power can be set according to clothing information. Exemplarily, the clothing information is the number of clothes. If the number of clothes to be dried is large, a relatively large first power can be set to output more electromagnetic wave energy, thereby ensuring that the clothes to be dried that are far away from the waveguide slot antenna array can also be dried quickly, which is conducive to shortening the drying time of clothes and improving the drying effect. Preferably, the first power is 450W. The first power can also be adjusted according to the actual needs of the user, and can also be set to any other value such as 400W or 500W.
[0108] Optionally, the second power can be set according to the clothing information. For example, the clothing information is the number of clothes. If the number of clothes to be dried is large, a relatively large second power can be set to output more electromagnetic wave energy, thereby ensuring that the clothes to be dried that are far away from the waveguide slot antenna array can also be dried quickly, which is conducive to shortening the drying time of clothes and improving the drying effect. Preferably, the second power is 300W. The second power can also be adjusted according to the actual needs of the user, and can also be set to any other value such as 250W or 350W.
[0109] Optionally, the third power can be set according to clothing information. Exemplarily, the clothing information is the number of clothes. If the number of clothes to be dried is large, a relatively large third power can be set to output more electromagnetic wave energy, thereby ensuring that the clothes to be dried that are far away from the waveguide slot antenna array can also be dried quickly, which is conducive to shortening the drying time of clothes and improving the drying effect. Preferably, the third power is 150W. The third power can also be adjusted according to the actual needs of the user, and can also be set to any other value such as 100W or 200W.
[0110] Optionally, the working parameters of the magnetron also include working time. In this way, the embodiment of the present disclosure can determine the output power and working time of the magnetron according to the air humidity detected by the humidity sensor, and by controlling the magnetron to continuously operate for a corresponding working time at a corresponding output power, the electromagnetic field strength in the drying chamber can be reasonably set, which is conducive to shortening the clothing drying time and improving the drying effect. When the operating time of the magnetron exceeds the corresponding working time, the processor ends this round of control and re-controls the humidity sensor to detect new air humidity to start the judgment of the next round of control until the air humidity drops to an extremely low value, at which time it is confirmed that the clothing has been dried.
[0111] Based on the above dryer, combined Figure 7 As shown, the embodiment of the present disclosure provides another control method for a clothes dryer, comprising:
[0112] S201, the processor controls the humidity sensor to detect air humidity.
[0113] S202: The processor adjusts the working parameters of the magnetron according to the air humidity to transmit electromagnetic wave energy to the first waveguide slot antenna array and the second waveguide slot antenna array.
[0114] By adopting the control method for a clothes dryer provided by the embodiment of the present disclosure, the RF module is operated to radiate electromagnetic waves into the drying chamber, so that the moisture in the clothes to be dried can be quickly heated, which is conducive to shortening the drying time of the clothes and improving the drying effect. In addition, the RF structure of the magnetron and the waveguide slot antenna array used in the embodiment of the present disclosure can reasonably decompose the electromagnetic wave energy generated by the magnetron to achieve dispersed radiation of the electromagnetic wave, which is conducive to avoiding the situation where the electromagnetic wave in the drying chamber is locally accumulated and causes damage to the clothes. At the same time, the embodiment of the present disclosure can make the electromagnetic waves in the drying chamber relatively evenly distributed by symmetrically arranging the first waveguide slot antenna array and the second waveguide slot antenna array on both sides of the drying box, so as to improve the uneven heating phenomenon in the horizontal direction caused by the attenuation of the electromagnetic wave in the drying chamber, which is conducive to improving the uniformity of clothes drying. In addition, the embodiment of the present disclosure also detects the humidity of the air flowing through the clothes by a humidity sensor arranged at the bottom of the drying chamber to judge the water content of the clothes to be dried, and adjusts the working parameters of the magnetron accordingly, so that the electromagnetic field strength in the drying chamber can be reasonably set, which is conducive to giving full play to the advantages of the electromagnetic wave heating method. Furthermore, the disclosed embodiment can timely adjust the RF module power amplifier when the moisture content of the clothes to be dried decreases, thereby effectively avoiding local overheating or electromagnetic ignition inside the dryer, which is beneficial to improving the reliability of clothes drying.
[0115] Optionally, the processor adjusts the working parameters of the magnetron according to the air humidity to transmit electromagnetic wave energy to the first waveguide slot antenna array and the second waveguide slot antenna array, including: the processor adjusts the working parameters of the first magnetron according to the first air humidity to transmit electromagnetic wave energy to the first waveguide slot antenna array; the processor adjusts the working parameters of the second magnetron according to the second air humidity to transmit electromagnetic wave energy to the second waveguide slot antenna array. In this way, the embodiment of the present disclosure can set relatively independent radio frequency control schemes for the humidity conditions of the clothes to be dried on the left and right sides of the drying chamber, respectively, and by adjusting the working parameters of the corresponding magnetrons, the first waveguide slot antenna array and the second waveguide slot antenna array can both output relatively appropriate electromagnetic wave energy, thereby realizing the separate control of the electromagnetic field strength on the left and right sides of the drying chamber, which is conducive to improving the uniformity of drying the clothes on the left and right sides.
[0116] Optionally, the processor adjusts the working parameters of the first magnetron according to the first air humidity, including: when the first air humidity is greater than or equal to the first humidity threshold, the processor controls the first magnetron to operate at the first power; or, when the first air humidity is less than the first humidity threshold and greater than or equal to the second humidity threshold, the processor controls the first magnetron to operate at the second power; or, when the first air humidity is less than the second humidity threshold and greater than or equal to the third humidity threshold, the processor controls the first magnetron to operate at the third power. Wherein, the first humidity threshold is greater than the second humidity threshold, the second humidity threshold is greater than the third humidity threshold, the first power is greater than the second power, and the second power is greater than the third power. In this way, the embodiment of the present disclosure can judge the moisture content of the clothes on the first side of the drying chamber by comparing the magnitude relationship between the detected first air humidity and multiple preset humidity thresholds. When the first air humidity is greater than or equal to the first humidity threshold, it indicates that the air humidity flowing through the clothes on the first side of the drying chamber is too high, and the moisture content of the clothes on this side is extremely high. Therefore, the embodiment of the present disclosure controls the first magnetron to operate at a relatively large first power to increase the electromagnetic wave energy transmitted to the first waveguide slot antenna array, so that the electromagnetic field strength on the first side of the drying chamber can be effectively enhanced, which is beneficial to improving the drying effect of clothes with extremely high water content. When the first air humidity is less than the first humidity threshold and greater than or equal to the second humidity threshold, it indicates that the air humidity flowing through the clothes on the first side of the drying chamber is slightly high, and the clothes on this side have a high water content at this time. Therefore, the embodiment of the present disclosure controls the first magnetron to operate at a slightly larger second power to slightly increase the electromagnetic wave energy transmitted to the first waveguide slot antenna array, so that the electromagnetic field strength on the first side of the drying chamber can be appropriately enhanced, which is beneficial to improving the drying effect of clothes with high water content. When the first air humidity is less than the second humidity threshold and greater than or equal to the third humidity threshold, it indicates that the air humidity flowing through the clothes on the first side of the drying chamber is low, and the clothes on this side have a low water content at this time. Therefore, the embodiment of the present disclosure controls the first magnetron to operate at a smaller third power to reduce the electromagnetic wave energy transmitted to the first waveguide slot antenna array, thereby appropriately weakening the electromagnetic field strength on the first side of the drying chamber, which is beneficial to avoiding local overheating or electromagnetic ignition inside the dryer and improving the reliability of clothing drying.
[0117] Optionally, the control method for the clothes dryer further includes: when the first air humidity is less than the third humidity threshold, the processor controls the first magnetron to stop working. In this way, when the first air humidity is less than the third humidity threshold, it indicates that the air humidity flowing through the clothes on the first side of the drying chamber is extremely low, and at this time the water content of the clothes on this side is extremely low, and drying has been basically achieved. Therefore, the embodiment of the present disclosure controls the first magnetron to stop working, which can effectively avoid local overheating or electromagnetic ignition inside the clothes dryer while saving electric energy, which is conducive to improving the reliability of clothes drying.
[0118] Optionally, the processor adjusts the working parameters of the second magnetron according to the second air humidity, including: when the second air humidity is greater than or equal to the first humidity threshold, the processor controls the second magnetron to operate at the first power; or, when the second air humidity is less than the first humidity threshold and greater than or equal to the second humidity threshold, the processor controls the second magnetron to operate at the second power; or, when the second air humidity is less than the second humidity threshold and greater than or equal to the third humidity threshold, the processor controls the second magnetron to operate at the third power. Wherein, the first humidity threshold is greater than the second humidity threshold, the second humidity threshold is greater than the third humidity threshold, the first power is greater than the second power, and the second power is greater than the third power. In this way, the embodiment of the present disclosure can judge the moisture content of the clothes on the second side of the drying chamber by comparing the magnitude relationship between the detected second air humidity and multiple preset humidity thresholds. When the second air humidity is greater than or equal to the first humidity threshold, it indicates that the air humidity flowing through the clothes on the second side of the drying chamber is too high, and the moisture content of the clothes on this side is extremely high. Therefore, the embodiment of the present disclosure controls the second magnetron to operate at a relatively large first power to increase the electromagnetic wave energy transmitted to the second waveguide slot antenna array, so that the electromagnetic field strength on the second side of the drying chamber can be effectively enhanced, which is beneficial to improving the drying effect of clothes with extremely high water content. When the second air humidity is less than the first humidity threshold and greater than or equal to the second humidity threshold, it indicates that the air humidity flowing through the clothes on the second side of the drying chamber is slightly higher, and the clothes on this side have a higher water content at this time. Therefore, the embodiment of the present disclosure controls the second magnetron to operate at a slightly larger second power to slightly increase the electromagnetic wave energy transmitted to the second waveguide slot antenna array, so that the electromagnetic field strength on the second side of the drying chamber can be appropriately enhanced, which is beneficial to improving the drying effect of clothes with high water content. When the second air humidity is less than the second humidity threshold and greater than or equal to the third humidity threshold, it indicates that the air humidity flowing through the clothes on the second side of the drying chamber is relatively low, and the clothes on this side have a relatively low water content at this time. Therefore, the embodiment of the present disclosure controls the second magnetron to operate at a smaller third power to reduce the electromagnetic wave energy transmitted to the second waveguide slot antenna array, thereby appropriately weakening the electromagnetic field strength on the second side of the drying chamber, which is beneficial to avoiding local overheating or electromagnetic ignition inside the dryer, and is beneficial to improving the reliability of clothing drying.
[0119] Optionally, the control method for the clothes dryer further includes: when the second air humidity is less than the third humidity threshold, the processor controls the second magnetron to stop working. In this way, when the second air humidity is less than the third humidity threshold, it indicates that the air humidity flowing through the clothes on the second side of the drying chamber is extremely low, and at this time the water content of the clothes on this side is extremely low, and drying has been basically achieved. Therefore, the embodiment of the present disclosure controls the second magnetron to stop working, which can save electric energy while effectively avoiding the occurrence of local overheating or electromagnetic ignition inside the clothes dryer, which is conducive to improving the reliability of clothes drying.
[0120] Based on the above dryer, combined Figure 8 As shown, the embodiment of the present disclosure provides another control method for a clothes dryer, comprising:
[0121] S301, the processor controls the humidity sensor to detect air humidity.
[0122] S302: The processor adjusts the working parameters of the magnetron according to the air humidity to transmit electromagnetic wave energy to the first waveguide slot antenna array and the second waveguide slot antenna array.
[0123] S303: The processor controls the operation of the heat pump module according to the air humidity to deliver hot air to the clothes drying chamber.
[0124] By adopting the control method for a clothes dryer provided by the embodiment of the present disclosure, the RF module is operated to radiate electromagnetic waves into the drying chamber, so that the moisture in the clothes to be dried can be quickly heated, which is conducive to shortening the drying time of the clothes and improving the drying effect. In addition, the RF structure of the magnetron and the waveguide slot antenna array used in the embodiment of the present disclosure can reasonably decompose the electromagnetic wave energy generated by the magnetron to achieve dispersed radiation of the electromagnetic wave, which is conducive to avoiding the situation where the electromagnetic wave in the drying chamber is locally accumulated and causes damage to the clothes. At the same time, the embodiment of the present disclosure can make the electromagnetic waves in the drying chamber relatively evenly distributed by symmetrically arranging the first waveguide slot antenna array and the second waveguide slot antenna array on both sides of the drying box, so as to improve the uneven heating phenomenon in the horizontal direction caused by the attenuation of the electromagnetic wave in the drying chamber, which is conducive to improving the uniformity of clothes drying. In addition, the embodiment of the present disclosure also detects the humidity of the air flowing through the clothes by a humidity sensor arranged at the bottom of the drying chamber to judge the water content of the clothes to be dried, and adjusts the working parameters of the magnetron accordingly, so that the electromagnetic field strength in the drying chamber can be reasonably set, which is conducive to giving full play to the advantages of the electromagnetic wave heating method. Moreover, the disclosed embodiment can timely adjust the RF module amplifier when the moisture content of the clothes to be dried decreases, thereby effectively avoiding local overheating or electromagnetic ignition inside the dryer, which is beneficial to improving the reliability of clothes drying. At the same time, the disclosed embodiment also controls the operation of the heat pump module according to the detected air humidity to deliver a suitable degree of hot air to the drying chamber, which is beneficial to further shorten the clothes drying time and improve the drying effect. Through the coordinated work of the heat pump heating method and the electromagnetic wave heating method, the disclosed embodiment can configure a suitable drying scheme, which is beneficial to improving the uniformity of clothes drying.
[0125] Optionally, the processor controls the operation of the heat pump module according to the air humidity to deliver hot air to the drying chamber, including: the processor determines the operation parameters of the heat pump module according to the third air humidity; the processor controls the heat pump module to operate according to the operation parameters to deliver hot air to the drying chamber. In this way, the embodiment of the present disclosure can set an adaptive operation scheme for the heat pump module in combination with the humidity of the middle clothes in the drying chamber. By controlling the heat pump module to operate with appropriate operation parameters, the embodiment of the present disclosure can adjust the amount of hot air and / or the temperature of hot air delivered by the heat pump module to the drying chamber to compensate for the poor electromagnetic wave drying effect of the middle clothes, thereby facilitating the improvement of the uniformity of clothes drying.
[0126] Optionally, the processor determines the operating parameters of the heat pump module according to the third air humidity, including: when the third air humidity is greater than or equal to the fourth humidity threshold, the processor determines the operating parameters of the heat pump module to be the first operating parameters; or, when the third air humidity is less than the fourth humidity threshold and greater than or equal to the fifth humidity threshold, the processor determines the operating parameters of the heat pump module to be the second operating parameters; or, when the third air humidity is less than the fifth humidity threshold and greater than or equal to the sixth humidity threshold, the processor determines the operating parameters of the heat pump module to be the third operating parameters; or, when the third air humidity is less than the sixth humidity threshold and greater than or equal to the seventh humidity threshold, the processor determines the operating parameters of the heat pump module to be the fourth operating parameters. Wherein, the fourth humidity threshold is greater than the fifth humidity threshold, the fifth humidity threshold is greater than the sixth humidity threshold, and the sixth humidity threshold is greater than the seventh humidity threshold. In this way, the disclosed embodiment can judge the moisture content of the middle clothes in the drying chamber by comparing the detected third air humidity with multiple preset humidity thresholds, and determine the operating parameters of the heat pump module accordingly, which is beneficial to deliver a suitable amount of hot air and / or hot air temperature to the drying chamber to compensate for the poor electromagnetic wave drying effect of the middle clothes, thereby helping to better improve the uniformity of clothing drying.
[0127] Optionally, the operating parameters of the heat pump module include part or all of the operating frequency of the compressor, the opening of the throttle valve, the speed of the exhaust fan, and the speed of the return air fan. In this way, by adjusting the above operating parameters, the embodiment of the present disclosure can reasonably adjust the hot air volume and / or hot air temperature delivered by the heat pump module to the drying chamber to compensate for the current situation of poor electromagnetic wave drying effect of the middle clothes, thereby facilitating the improvement of the uniformity of clothes drying.
[0128] Optionally, the control method for the clothes dryer further includes: when the third air humidity is less than the seventh humidity threshold, the processor controls the heat pump module to stop working. In this way, when the third air humidity is less than the seventh humidity threshold, it indicates that the air humidity flowing through the middle clothes in the clothes drying chamber is extremely low, and the moisture content of the middle clothes is extremely low at this time, and the drying has been basically achieved. Therefore, the embodiment of the present disclosure controls the heat pump module to stop working to avoid energy waste caused by ineffective work.
[0129] Optionally, the fourth humidity threshold can be set according to clothing information. For example, the clothing information is the material of the clothing. If the material of the clothing to be dried is down material that is difficult to dry, a relatively small fourth humidity threshold can be set to accelerate the rapid evaporation of water in the clothing to be dried through a larger hot air volume and / or hot air temperature, thereby shortening the clothing drying time and improving the drying effect. Preferably, the fourth humidity threshold is 80%. The fourth humidity threshold can also be adjusted according to the actual needs of the user, and can also be set to any other value such as 75% or 85%.
[0130] Optionally, the fifth humidity threshold can be set according to clothing information. Exemplarily, the clothing information is clothing material. If the material of the clothing to be dried is down material that is difficult to dry, a relatively small fifth humidity threshold can be set to accelerate the rapid evaporation of water in the clothing to be dried through a larger hot air volume and / or hot air temperature, thereby helping to shorten the clothing drying time and improve the drying effect. Preferably, the fifth humidity threshold is 60%. The fifth humidity threshold can also be adjusted according to actual user needs, and can also be set to any other value such as 55% or 65%.
[0131] Optionally, the sixth humidity threshold can be set according to clothing information. For example, the clothing information is the material of the clothing. If the material of the clothing to be dried is down material that is difficult to dry, a relatively small sixth humidity threshold can be set to accelerate the rapid evaporation of water in the clothing to be dried through a larger hot air volume and / or hot air temperature, thereby helping to shorten the clothing drying time and improve the drying effect. Preferably, the sixth humidity threshold is 40%. The sixth humidity threshold can also be adjusted according to the actual needs of the user, and can also be set to any other value such as 35% or 45%.
[0132] Optionally, the seventh humidity threshold can be set according to clothing information. For example, the clothing information is the material of the clothing. If the material of the clothing to be dried is a polyester-cotton material that is less difficult to dry, a relatively large seventh humidity threshold can be set to shut down the heat pump module more promptly, thereby helping to avoid energy waste caused by ineffective work. Preferably, the seventh humidity threshold is 20%. The seventh humidity threshold can also be adjusted according to actual user needs, and can also be set to any other value such as 15% or 25%.
[0133] Optionally, after the processor controls the heat pump module to stop working, the process further includes: the processor controls the exhaust fan to continue to operate for a preset time. Preferably, the preset time is 5 minutes. In this way, the embodiment of the present disclosure can exhaust the hot and humid air in the drying chamber as much as possible, which is conducive to improving the intuitive feeling of the user when taking clothes.
[0134] Optionally, after the processor controls the exhaust fan to run continuously for a preset time, the process further includes: the processor controls the door to unlock; the processor sends a prompt message to the user to prompt that the clothes drying is complete. In this way, the embodiment of the present disclosure can unlock the door of the dryer and prompt the user that the clothes drying is complete, thereby facilitating the user to take the clothes in time.
[0135] Based on the above dryer, combined Fig. 9 As shown, the embodiment of the present disclosure provides another control method for a clothes dryer, comprising:
[0136] S401, the processor controls the humidity sensor to detect the first air humidity, the second air humidity and the third air humidity.
[0137] S402: The processor adjusts the operating parameters of the first magnetron according to the first air humidity to transmit electromagnetic wave energy to the first waveguide slot antenna array.
[0138] S403: The processor adjusts the operating parameters of the second magnetron according to the second air humidity to transmit electromagnetic wave energy to the second waveguide slot antenna array.
[0139] S404: The processor determines operating parameters of the heat pump module according to the third air humidity.
[0140] S405: The processor corrects the operating parameters of the heat pump module according to the first air humidity, the second air humidity, and the third air humidity.
[0141] S406: The processor controls the heat pump module to operate according to the operating parameters to deliver hot air to the clothes drying chamber.
[0142] By using the control method for a clothes dryer provided by the embodiment of the present disclosure, the heat pump module is operated to heat the air delivered to the clothes drying chamber, and the hot dry air entering the clothes drying chamber can take away the moisture on the clothes to achieve the effect of clothes drying. And by operating the radio frequency module to radiate electromagnetic waves into the clothes drying chamber, the moisture in the clothes to be dried can be quickly heated, which is conducive to shortening the clothes drying time and improving the drying effect. In addition, the radio frequency structure of the magnetron and the waveguide slot antenna array is adopted in the embodiment of the present disclosure, which can reasonably decompose the electromagnetic wave energy generated by the magnetron to achieve the dispersed radiation of the electromagnetic waves, which is conducive to avoiding the situation where the electromagnetic waves in the clothes drying chamber are locally accumulated and cause damage to the clothes. At the same time, the embodiment of the present disclosure can make the electromagnetic waves in the clothes drying chamber relatively evenly distributed by symmetrically arranging the first waveguide slot antenna array and the second waveguide slot antenna array on both sides of the clothes drying box, so as to improve the uneven heating phenomenon in the horizontal direction caused by the attenuation of the electromagnetic waves in the clothes drying chamber, which is conducive to improving the uniformity of clothes drying. In addition, the embodiment of the present disclosure also detects the air humidity flowing through the clothes on both sides and in the middle of the drying chamber through multiple humidity sensors arranged at the lower part of the drying chamber, so as to determine the moisture content of the clothes to be dried at different positions. By analyzing the first air humidity that can reflect the moisture content of the clothes on one side of the drying chamber, the embodiment of the present disclosure can adjust the working parameters of the first magnetron to control the electromagnetic field strength on that side of the drying chamber. And by analyzing the second air humidity that can reflect the moisture content of the clothes on the other side of the drying chamber, the embodiment of the present disclosure can adjust the working parameters of the second magnetron to control the electromagnetic field strength on the other side of the drying chamber. Therefore, the embodiment of the present disclosure can timely adjust the working parameters of the magnetron when the moisture content of the clothes to be dried decreases, thereby effectively avoiding the occurrence of local overheating or electromagnetic ignition inside the dryer, which is conducive to improving the reliability of clothes drying. By analyzing the third air humidity that can reflect the moisture content of the middle clothes in the drying chamber, the disclosed embodiment can preliminarily determine the operating parameters of the heat pump module, and adaptively correct the operating parameters of the heat pump module in combination with the numerical relationship between the first air humidity, the second air humidity and the third air humidity, so as to optimize the hot air volume and / or hot air temperature delivered by the heat pump module to the drying chamber, thereby compensating for the current situation of poor electromagnetic wave drying effect of the middle clothes, which is conducive to improving the uniformity of clothes drying. Therefore, the disclosed embodiment can more finely control the operation of the radio frequency module and the heat pump module, so as to better balance the uniformity and reliability of clothes drying.
[0143] Optionally, the processor corrects the operating parameters of the heat pump module according to the first air humidity, the second air humidity and the third air humidity, including: when the ratio of the third air humidity to the first air humidity is greater than the preset ratio, and / or the difference between the third air humidity and the first air humidity is greater than the preset difference, the processor corrects the operating parameters of the heat pump module to increase the amount of hot air and / or the temperature of hot air delivered to the drying chamber. In this way, the embodiment of the present disclosure can determine the degree of drying uniformity of the middle clothes and the clothes on both sides in the drying chamber by determining the ratio and / or difference of the third air humidity and the first air humidity. When the ratio is greater than the preset ratio and the difference is greater than the preset difference, it indicates that the third air humidity is larger than the first air humidity at this time, and the water content of the middle clothes in the drying chamber is higher at this time, and the clothes there are more difficult to be dried. Therefore, the embodiment of the present disclosure can correct the operating parameters of the heat pump module to increase the amount of hot air and / or the temperature of hot air delivered to the drying chamber, thereby compensating for the current situation of poor drying effect of the middle clothes, which is conducive to improving the uniformity of clothes drying.
[0144] Optionally, the processor corrects the operating parameters of the heat pump module according to the first air humidity, the second air humidity and the third air humidity, including: when the ratio of the third air humidity to the second air humidity is greater than the preset ratio, and / or the difference between the third air humidity and the second air humidity is greater than the preset difference, the processor corrects the operating parameters of the heat pump module to increase the amount of hot air and / or the temperature of hot air delivered to the drying chamber. In this way, the embodiment of the present disclosure can determine the degree of drying uniformity of the middle clothes and the clothes on both sides in the drying chamber by determining the ratio and / or difference of the third air humidity and the second air humidity. When the ratio is greater than the preset ratio and the difference is greater than the preset difference, it indicates that the third air humidity is larger than the second air humidity at this time, and the water content of the middle clothes in the drying chamber is higher at this time, and the clothes there are more difficult to be dried. Therefore, the embodiment of the present disclosure can correct the operating parameters of the heat pump module to increase the amount of hot air and / or the temperature of hot air delivered to the drying chamber, thereby compensating for the current situation of poor drying effect of the middle clothes, which is conducive to improving the uniformity of clothes drying.
[0145] Optionally, the processor modifies the operating parameters of the heat pump module to increase the amount of hot air and / or the temperature of hot air delivered to the clothes drying chamber, including: the processor increases the operating frequency of the compressor; and / or the processor increases the speed of the exhaust fan; and / or the processor increases the speed of the return air fan; and / or the processor reduces the opening of the throttle valve. In this way, by modifying the above operating parameters, the embodiment of the present disclosure can optimize the amount of hot air and / or the temperature of hot air delivered by the heat pump module to the clothes drying chamber to compensate for the current situation of poor drying effect of the intermediate clothes, thereby facilitating the improvement of the uniformity of clothes drying.
