[0032] The following will be combined with the embodiments and the drawings in the embodiments to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiment is only a sub-embodiment of a unit of the present invention, rather than an embodiment of the whole unit. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] In addition, in the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the disclosed embodiments. However, it is apparent that one or more embodiments may be implemented without these specific details. In other cases, known structures and devices are embodied in a schematic manner to simplify the accompanying drawings.

[0034] By performing the clothes drying operation in the bathroom, the utilization rate of the space can be effectively improved. However, in the process of realizing the present disclosure, the inventor found that the relevant clothes drying system cannot identify the position of the hanging part. The air outlet can only be set to automatically swing the wind in a predetermined trajectory. Therefore, in actual use, the swing area of ​​the air outlet is often larger than the area where the clothes need to be dried, resulting in unnecessary blowing areas, wasting energy, and increasing the drying time.

[0035] To address the deficiencies of the above-mentioned prior art, an embodiment of the present disclosure provides a clothes drying system suitable for a bathroom. The clothes drying system may include a drying device, a hanging device, a positioning device, and a control device. The drying device may be arranged in a target space. The drying device may be used to provide an airflow for drying a target object. The hanging device may be movably arranged in the target space. The target object may be hung on the hanging device. The positioning device may be used to determine a positioning signal of the hanging device. The control device may determine a drying area based on the positioning signal, and control the drying device to perform a drying operation based on the drying area.

[0036] According to the embodiment of the present disclosure, by setting a positioning device, the positioning signal of the suspension device can be determined. By setting a control device, the drying area can be determined based on the positioning signal, and the drying device can be controlled to perform drying operations based on the drying area, that is, by setting a positioning device and a control device, the position of the suspension device can be automatically identified, so that it is convenient for the user to move the suspension device, and the airflow can be blown to the drying area more accurately, thereby avoiding the waste of electricity caused by the airflow blowing to the non-drying area, and achieving the purpose of effectively avoiding the waste of electricity and improving the convenience of use.

[0040] Embodiment 1

[0041] Figure 1 A perspective view of a clothes drying system according to a first embodiment of the present disclosure is schematically shown. Figure 2 A cross-sectional view schematically shows a drying device according to a first embodiment of the present disclosure.

[0042] like Figure 1-Figure 2 As shown, the clothes drying system provided by the embodiment of the present disclosure may include a drying device 1, a detection device, a hanging device 2 and a control device 4. The drying device 1 and the hanging device 2 may be integrated or separated. In this embodiment, the drying device 1 and the hanging device 2 are separated as an example, and the hanging device 2 may be set anywhere in the bathroom. The clothes drying system may be used to dry clothes. The detection device may be set on the drying device 1 or on the hanging device 2.

[0043] The drying device 1 may be a device capable of discharging the gas sucked from the first space to the second space, that is, a device having a ventilation function. The drying device 1 may also be a device capable of heating the gas sucked from the first space and then discharging it to the first space, that is, a device having both ventilation and heating functions. For example, the drying device 1 may be a heating ventilator. The heating ventilator may be installed in the bathroom. While being used as a bathroom heater, the heating ventilator may also provide airflow for drying clothes. Under this use condition, the first space may be a bathroom, and the second space may be outside the bathroom. The drying device 1 may also be a device without a ventilation function, and only capable of heating the gas sucked from the first space and then discharging it to the first space. Under this use condition, the first space may be a bathroom.

[0044] The drying device 1 may include a shell 11, an air supply unit 14 and a heating unit 15. An air inlet 12, an air outlet 13 and an exhaust port may be formed on the shell 11. The air inlet 12 may be arranged at the bottom of the shell 11, facing the bathroom. The gas in the bathroom may enter the shell 11 through the air inlet 12. The air outlet 13 may also be arranged at the bottom of the shell 11, facing the bathroom. The gas in the shell 11 may flow out to the bathroom through the air outlet 13. The gas in the shell 11 may also flow out to the outside of the bathroom through the exhaust port. In an optional embodiment of the present disclosure, the air inlet 12, the air outlet 13 and the exhaust port on the shell 11 may be arranged at different positions of the shell 11 according to actual needs.

[0045] The air supply unit 14 can be arranged in the housing 11 and near the air inlet 12. The air supply unit 14 can be used to guide the gas in the bathroom to form an airflow, and enter the drying device 1 from the air inlet 12. The airflow can flow out of the drying device 1 from the air outlet 13. Further, the air supply unit 14 can include a motor, a fan blade and a snail shell. The fan blade and the motor can be located in the snail shell. The output shaft of the motor can be connected to a rotating shaft, and the fan blade can be connected to the rotating shaft. After the motor is powered on, the fan blade can be driven to rotate, so that the gas near the air inlet 12 in the bathroom can form an airflow, guide the airflow from the air inlet 12 into the housing 11, and flow to the air outlet 13 and / or the exhaust port. Two air supply units 14 can be provided, one of which can blow the gas inhaled from the air inlet 12 to the air outlet 13, and the other can blow the gas inhaled from the air inlet 12 out of the exhaust port. In addition, a wind path switching plate and an air supply unit 14 can also be provided in the drying device 1. The air path switching plate can rotate around the rotation axis of the air path switching plate to open the air outlet 13 or the exhaust port, or the air outlet 13 and the exhaust port can be opened at the same time. By changing the angle of the air path switching plate, the gas in the housing 11 can be discharged from the air outlet 13 and / or the exhaust port.

[0046] The heating unit 15 can be arranged in the housing 11 and close to the air outlet 13. Further, the heating unit 15 can be arranged on the upstream side of the air outlet 13. After the airflow enters the housing 11, it is heated by the heating unit 15 and then flows out of the drying device 1 to dry the clothes in the bathroom. The heating unit 15 can have two states: open and closed. When the heating unit 15 is in the open state, the airflow flowing through the heating unit 15 is heated by the heating unit 15. When the heating unit 15 is in the closed state, the airflow flowing through the heating unit 15 is not heated.

[0047] The control device 4 can be used to control the operation of the entire drying system. The control device 4 can be electrically connected to the heating unit 15, and control the state of the heating unit 15 by sending a signal, thereby changing the heating power of the heating unit 15. Controlling the state of the heating unit 15 can refer to controlling the heating unit 15 to switch between an on state and an off state. The control device 4 can be electrically connected to the air supply unit 14, and can control the speed of the motor by sending a signal, driving the fan blades to rotate, thereby changing the flow rate of the airflow.

[0048] The detection device can be arranged in the bathroom. The detection device can be used to detect physical parameters used to characterize the humidity of the clothes. That is, the physical parameters can be used to assist in calculating the moisture content of the clothes to be dried. The control device 4 can be used to determine the humidity of the clothes based on the changes in the multiple physical parameters, and then determine whether to end the drying operation of the drying device 1.

[0049] According to the embodiment of the present disclosure, the detection device can record the physical parameter once every preset time interval. Preferably, the preset time can be 2 seconds. That is, the detection device can record the value detected in even seconds. Further, the detection device can be a humidity sensor 3. Figure 2 As shown, the humidity sensor 3 can be installed in the drying device 1 and close to the air inlet 12. The humidity sensor 3 can be used to detect the bathroom humidity of the bathroom, that is, the humidity of the clothes can be characterized by the bathroom humidity, that is, the physical parameter can be the bathroom humidity, and the bathroom humidity can also be expressed as the space humidity. The humidity sensor 3 is used to detect the humidity of the air flow sucked into the shell 11 by the air supply part 14, and the humidity here is basically consistent with the indoor space humidity. In this embodiment, a humidity sensor 3 and a temperature sensor are provided. The humidity sensor 3 obtains the relative humidity of the target space, and converts the relative humidity into absolute humidity using the temperature detected by the temperature sensor. At this time, the temperature sensor can also be set at a position close to the air inlet 12. The humidity sensor 3 and the temperature sensor can be replaced by a temperature and humidity sensor.

[0050] According to the embodiment of the present disclosure, the control device 4 can determine the difference between the multiple physical parameters and the multiple physical parameters obtained by the detection device in the previous judgment period based on the multiple physical parameters obtained in the current judgment period, and use the average value of the multiple differences as the change amount, and determine to end the drying operation when the change amount is less than a predetermined value. Determining the change amount by the difference of multiple physical parameters can make the obtained change amount more accurate.

[0051] Specifically, the last judgment period can be represented as T1. The current judgment period can be represented as T2. The control device 4 can obtain multiple physical parameters in the T2 period. The differences between the multiple physical parameters in the T2 period and the multiple physical parameters in the T1 period are calculated respectively, and the average value of the multiple differences is used as the change amount of the physical parameters at the T2 time relative to the T1 time. Specifically, the multiple physical parameters in the T2 period can be represented as M 21 、M 22 ,……,M 2n The multiple physical parameters in the T1 period can be expressed as M 11 、M 12 ,……,M 1n The difference between the physical parameters at time T1 and time t1 can be expressed as △M 21-11 , △M 22-11 ,……,△M 2n-1n . Change = (△M 21-11 +△M 22-12 +……+△M 2n-1n ) / n. △M 2n-1n =M 2n -M 1n n can be expressed as the number of physical parameters obtained during the T1 period. 21 、M 22 ,……,M 2n The time interval can be obtained by 11 、M 12 ,……,M 1n The time intervals are the same.

[0052] For example, the physical parameters of 5 minutes before the current judgment moment can be obtained. For example, when the current judgment moment is the 60th minute of the drying operation, the physical parameters between the 55th minute and the 60th minute can be obtained as multiple physical parameters in the current judgment period, that is, the current judgment period is the 55th minute to the 60th minute. The physical parameters between the 25th minute and the 30th minute can be obtained as multiple physical parameters in the previous judgment period, that is, the previous judgment period is the 25th minute to the 30th minute. It can be obtained every 2 seconds, that is, 150 physical parameters can be obtained in both the current judgment period and the current judgment period. The average value of the difference between the 150 physical parameters obtained in the two time periods can be used as the variation at the current judgment moment. In this way, the physical parameters caused by the instability of the humidity sensor 3 can be prevented from fluctuating greatly, thereby reducing the occurrence of misjudgment.

[0053] According to the embodiment of the present disclosure, when the change amount is less than the preset value, the control device 4 can control the air supply unit 14 and the heating unit 15 to stop working. That is, the drying device 1 stops running, that is, when the change amount of the physical parameter is less than the preset value, it can be represented as the change amount of the moisture content of the clothes is reduced to at least less than the preset value corresponding to the humidity, that is, it can be represented as the wet clothes are dried.

[0054] According to an embodiment of the present disclosure, the current judgment period may include a first judgment period. The previous judgment period includes a second judgment period. The control device 4 may determine the difference of multiple physical parameters based on multiple bathroom humidity values ​​obtained by the humidity sensor 3 in the first judgment period and multiple bathroom humidity values ​​obtained in the second judgment period. When the change in the physical parameter is less than a predetermined value, it may be determined to end the drying operation.

[0055] In detail, the variation can be determined by the following steps:

[0056] STEP1: Obtain the bathroom humidity M detected by the detection device during the T1 period 11 、M 12 ,……,M 1n And obtain the bathroom humidity M detected by the detection device in the T2 period after the T1 period 21 、M 22 ,……,M 2n Among them, M 11 With M 21 The time interval, and M 1n With M 2n The time interval is the same. The moment T1 can be characterized as the first judgment period. The moment T2 can be characterized as the second judgment period.

[0057] STEP 2: Calculate the difference of multiple physical parameters, that is, the difference of bathroom humidity. Based on the multiple bathroom humidity values ​​obtained by the humidity sensor in the first judgment period and the multiple bathroom humidity values ​​obtained in the second judgment period, determine the difference of multiple physical parameters. For example, the difference of one physical parameter can be expressed as △M 2n-1n =M 2n -M 1n .

[0058] STEP3: Calculate the change. The change can be represented as the average value of the difference between multiple physical parameters. That is, the change = (△M 21-11 +△M 22-12 +……+△M 2n-1n ) / n. n can be expressed as the number of bathroom humidity values ​​obtained during the T1 period.

[0059] According to an embodiment of the present disclosure, the control device 4 can also be used to take the difference between the physical parameter obtained at the current moment and the physical parameter obtained at the previous moment as a change. For example, the difference between the physical parameter at moment T1 and the physical parameter at moment T2 can be taken as a change. Specifically, the difference between the physical parameter obtained at the 25th minute and the physical parameter obtained at the 30th minute is taken as a change. For example, the difference between the physical parameter obtained at the 20th second and the physical parameter obtained at the 22nd second is taken as a change. Among them, moment T1, the 25th minute and the 20th second can be represented as the previous moment. Moment T2, the 30th minute and the 22nd second can be represented as the current moment. The time interval between the previous moment and the current moment can be set as needed. Further, in this embodiment, the physical parameter can be the humidity in the bathroom. For example, the change = M t1 -M t0 Among them, M t1 The bathroom humidity at the current moment can be obtained, M t0 The humidity in the bathroom can be obtained at the last moment.

[0060] According to the embodiment of the present disclosure, the control device 4 can adjust the drying power of the drying device 1 based on the humidity of the bathroom. For example, the drying power can be increased when the humidity is detected to be high, and the drying power can be reduced when the humidity is detected to be low.

[0061] The following takes the drying device 1 as a heating ventilation fan as an example to illustrate the operation process of the heating mode of the drying device 1.

[0062] When the heating ventilator is turned on in drying mode, the air in the room forms an airflow and enters the housing 11 from the air inlet 12 under the action of the air supply unit 14. When the air outlet is closed and the air outlet 13 is opened, the airflow entering from the air inlet 12 is brought to the heating unit 15 and is discharged from the air outlet 13 after being heated by the heating unit 15. In other embodiments, in drying mode, after the air enters the housing 11 from the air inlet 12, part of the air is discharged from the air outlet to the outside of the bathroom, and the other part is heated by the heating unit 15 and discharged from the air outlet 13 to the bathroom.

[0063] The air outlet 13 can be arranged opposite to the suspension device 2. After the drying mode is turned on, the humidity sensor 3 can start to detect the humidity in the bathroom. The humidity sensor 3 can be arranged to detect the humidity of the airflow sucked in by the heating ventilation fan in real time and record each physical parameter detected, that is, the humidity in the bathroom. Since the moisture content of wet clothes is relatively large, the humidity in the bathroom detected by the humidity sensor 3 is relatively large at the initial start-up. As the drying time increases, the moisture content of the clothes gradually decreases, and the humidity in the bathroom also gradually decreases. That is, the bathroom humidity M1>bathroom humidity M2>bathroom humidity M n The bathroom humidity M2 can be detected after the bathroom humidity M1 is obtained and the time period t1. n It can be detected after obtaining the bathroom humidity M1, tn period, where n is greater than or equal to 1.

[0064] According to the embodiment of the present disclosure, the control device can calculate the difference △M between the bathroom humidity M2 and the bathroom humidity M1 2-1 . Then calculate the bathroom humidity M n-1 and bathroom humidity M n The difference △M n-n-1 The time interval between obtaining the bathroom humidity M2 and the bathroom humidity M1 is the same as the time interval between obtaining the bathroom humidity M n-1 and bathroom humidity M n The time interval is the same. Where n can represent the number of bathroom humidity values ​​obtained, and n can be a positive integer greater than or equal to 2. The △M obtained by calculation 2-1 , △M 3-2 ,……,△M n-n-1 , a curve of the change process of the bathroom humidity can be obtained, thereby representing the process of the clothes from being wet to being dried. The curve can be parabolic and gradually decrease until it approaches a straight line. When the curve approaches a straight line, it can be indicated that the change of the moisture content of the clothes tends to be stable, that is, the drying operation can be ended.

[0065] Further, the control device can compare the change amount with a predetermined value. When the change amount is less than the predetermined value, preferably, the predetermined value can be set to -0.2 g / m 3 That is, the change is less than -0.2g / m 3In this case, the drying operation can be ended. At this time, the control device can control the air supply unit and the heating unit to stop working. The disclosed embodiment can automatically determine whether to end the drying operation according to the change of the humidity in the bathroom, and can realize intelligent control of the drying time, thereby avoiding wasting electricity.

[0066] Embodiment 2

[0067] Figure 3 A perspective view of a suspension device according to an embodiment of the present disclosure is schematically shown. Figure 4 A cross-sectional view of a suspension device according to an embodiment of the present disclosure is schematically shown. Figure 5 Schematically shows Figure 4 Enlarged view of point A in the middle.

[0068] The detection device of this embodiment can be a force sensor. The force sensor can be connected to the suspension device 2. The structure of the other drying device 1 is the same as that of the first embodiment and will not be described in detail. Figure 1-5 As shown, the hanging device 2 of this embodiment can be fixed on the wall and is arranged separately from the drying device 1. Similarly, the drying device 1 can be a bathroom heater or an ordinary heater.

[0069] The two ends of the hanging device 2 are connected to the wall, that is, the hanging device 2 is set on the wall by screws or suction cup structures. The hanging device 2 may include a hanging portion 21 and a fixing portion 22. Clothes may be hung on the hanging portion 21, and the hanging portion 21 may be a clothes drying rod. The fixing portion 22 may be used to support the hanging portion 21. The force sensor may be a pressure sensor 5. The pressure sensor 5 may be arranged inside the fixing portion 22. A mounting groove for mounting the pressure sensor 5 may be arranged inside the fixing portion 22, and the hanging portion 21 may be arranged on the pressure sensor 5. A communication portion 10 may also be arranged inside the fixing portion 22. The communication portion 10 may be connected to the force sensor. The pressure sensor 5 may be used to obtain the force applied by the clothes hung on the hanging portion 21 to the hanging portion 21, that is, the physical parameter obtained by the pressure sensor 5 is the force. After obtaining the force applied by the clothes hung on the hanging portion 21 to the hanging portion 21, the pressure sensor 5 transmits the physical parameter representing the force to the control device 4 through the communication portion 10. The control device 4 may be installed in the drying device 1. In this embodiment, the force may be pressure.

[0070] According to an embodiment of the present disclosure, the current judgment period may include a third judgment period. The previous judgment period may include a fourth judgment period. The control device 4 may also determine the difference between multiple physical parameters based on multiple forces obtained by the pressure sensor 5 in the third judgment period and multiple forces obtained in the fourth judgment period. The detection device may record the detected value once every preset time interval. Preferably, the preset time may be 2 seconds. That is, the detection device may record the value detected at even seconds.

[0071] In detail, the variation can be determined by the following steps:

[0072] STEP1: Obtain the force P detected by the detection device during the T1 period 11 , P 12 ,……,P 1n And obtain the force P detected by the detection device in the T2 period after the T1 period 21 , P 22 ,……,P 2n Among them, P 11 With P 21 The time interval and P 1n With P 2n The time interval is the same. The moment T1 can be characterized as the third judgment period. The moment T2 can be characterized as the fourth judgment period.

[0073] STEP 2: Calculate the difference of multiple physical parameters, that is, the difference of the applied force. Based on the multiple applied forces obtained by the pressure sensor in the third judgment period and the multiple applied forces obtained in the fourth judgment period, determine the difference of multiple physical parameters. For example, the difference of one physical parameter can be expressed as △P 2n-1n =P 2n -P 1n .

[0074] STEP3: Calculate the change. The change can be represented as the average value of the difference between multiple physical parameters. That is, the change = (△P 21-11 +△P 22-12 +……+△P 2n-1n ) / n. n can be expressed as the number of forces obtained during the T1 period.

[0075] According to an embodiment of the present disclosure, the control device 4 can also be used to take the difference between the force obtained at the current moment and the force obtained at the previous moment as a change. For example, the difference between the force at moment T1 and the force at moment T2 can be taken as a change. Specifically, the difference between the force obtained at the 25th minute and the force obtained at the 30th minute is taken as a change. For example, the difference between the force obtained at the 20th second and the force obtained at the 22nd second is taken as a change. Among them, moment T1, the 25th minute and the 20th second can be represented as the previous moment. Moment T2, the 30th minute and the 22nd second can be represented as the current moment. The time interval between the previous moment and the current moment can be set as needed. The time interval between the previous moment and the current moment can be set as needed. For example, P1 can be the force obtained at the current moment, P t0 It can be the force obtained at the last moment. That is, the change = P t1 -P t0 .

[0076] Furthermore, two pressure sensors 5 can be provided. The pressure sensors 5 can be located at both ends of the suspension device 2, respectively. Furthermore, the pressure sensor 5 can also be provided as one. By providing the pressure sensor 5, the pressure of the suspension part 21 on the fixing part 22 can be detected, that is, the weight of the clothes can be detected. Specifically, the pressure of the suspension part 21 on the fixing part 22 can be obtained by detecting the deformation of the suspension part 21, and by converting the pressure into an electrical signal and outputting it to the control device 4‌, the increase or decrease in the water content of the clothes can be confirmed. Furthermore, the detection device can also be a weight sensor.

[0077] After the drying mode is turned on, the pressure sensor 5 can start to detect the pressure of the hanging part 21 on the fixing part 22. The pressure sensor 5 can be set to detect the change of the pressure of the hanging part 21 on the fixing part 22 in real time and record each detected physical parameter, that is, the pressure value. Since the moisture content of wet clothes is relatively large, the detection result of the pressure sensor 5 is relatively large at the beginning of the startup. As the drying time increases, the moisture content of the clothes gradually decreases, and the detection result of the pressure sensor 5 gradually decreases. That is, pressure value P1>pressure value P2>pressure value P m The pressure value P2 may be detected after the pressure value P1 is obtained and the time period t1 has passed. m It can be detected after obtaining the pressure value P1, tm period. m is greater than or equal to 1.

[0078] According to the embodiment of the present disclosure, the control device can calculate the difference ΔP between the pressure value P1 and the pressure value P2 2-1 . Then calculate the pressure value P m With pressure value P m-1 The difference △P m-m-1 The time interval between obtaining the pressure value P1 and the pressure value P2 is the same as the time interval between obtaining the pressure value P m With pressure value P m-1 The time interval is the same. Wherein, m can represent the number of pressure values ​​obtained, and m can be a positive integer greater than or equal to 2. The △P obtained by calculation 2-1 , △P 3-2 ,……,△P m-m-1 , a curve of the pressure change of the hanging part on the fixed part can be obtained, which can reflect the process of the clothes from being wet to being dried. The curve should be able to gradually decrease in a parabola until it tends to be a straight line. When the curve tends to be a straight line, it can be said that the change in the moisture content of the clothes tends to be stable.

[0079] Furthermore, the control device 4 can compare the change with a predetermined value. When the change is less than the predetermined value, preferably, the predetermined value can be set to 0.5g. That is, when the change is less than 0.5g, the drying operation can be terminated. At this time, the control device 4 can control the air supply unit 14 and the heating unit 15 to stop working. The present invention can automatically determine whether to terminate the drying operation according to the weight change of the clothes, and can realize intelligent control of the drying time, thereby avoiding wasting electricity.

[0086] Figure 8 A perspective view of a clothes drying system according to a fourth embodiment of the present disclosure is schematically shown. Fig. 9A cross-sectional view of a drying device according to a fourth embodiment of the present disclosure is schematically shown.

[0087] The structure of the drying device 1 of this embodiment is the same as that of the first embodiment, and will not be described in detail. The drying device 1 can be separated from the hanging device 2. The hanging device 2 can be set at any position in the bathroom. The hanging device 2 can be moved in the bathroom.

[0088] like Figure 8-Figure 9 According to an embodiment of the present disclosure, the drying system may further include a positioning device. The positioning device may include at least two groups of positioning tags 7 and a receiving device 8. One group of positioning tags 7 may be set on the hanging portion 21. Another group of positioning tags 7 may be set on the drying device 1. The positioning tags 7 may be used to transmit positioning signals. The receiving device 8 may be used to receive positioning signals. The control device 4 may determine the position information of the drying area relative to the drying device 1 based on the positioning signal, and control the drying device 1 to perform a drying operation based on the position information.

[0089] Furthermore, the positioning device may be a device that uses the characteristics of high-frequency electromagnetic waves to perform distance measurement and target recognition. The control device 4 may calculate the position information of the suspension portion 21 based on the time from the electromagnetic wave sending the signal to the receiving signal.

[0090] Specifically, the positioning tag 7 can emit pulses at a certain frequency, measure the distance with the receiving device 8 at a known position, calculate the transmission time of the signal, and thus determine the position of the positioning tag 7. Specifically, the positioning tag 7 can be a UWB tag (UltraWideband, carrier-free communication technology). The receiving device 8 can be a positioning base station. Furthermore, in other embodiments, millimeter wave technology can also be used. The drying area is located or the target object is identified by millimeter wave technology. When the control device 4 receives the range signal of the drying area or the target object, the angle of the air guide part 9 can be controlled to make the air passing through the heating part 15 blow toward the drying area or the clothes.

[0091] According to an embodiment of the present disclosure, a group of positioning tags 7 located on the hanging portion 21 may be a first positioning tag 7 group. Two or more positioning tags 7 may be provided in the first positioning tag 7 group. The drying area may include an area between any two positioning tags 7 in the first positioning tag 7 group. For example, the first positioning tag 7 group may include a first positioning tag 7 and a second positioning tag 7. The first positioning tag 7 may be provided at a first end of the hanging portion 21. The second positioning tag 7 may be provided at a second end opposite to the first end of the hanging portion 21. The area between the first positioning tag 7 and the second positioning tag 7 may be represented as a drying area. Another group of positioning tags 7 provided on the drying device 1 may be a second positioning tag 7 group. The second positioning tag 7 group may also be provided with only one positioning tag 7.

[0092] According to the embodiment of the present disclosure, at least one receiving device 8 may be provided. The receiving device 8 may be provided in the drying device 1 or in the bathroom. In order to make the measurement data more accurate, in this embodiment, one receiving device 8 is provided in each of the four corners of the bathroom, and a signal network is established through signal transmission with the positioning tag 7, so as to determine the position of the drying device 1 and the drying area, thereby improving the accuracy and efficiency of the drying area detection.

[0093] According to the embodiment of the present disclosure, the drying device 1 may further include an air guide portion 9. The air guide portion 9 may be disposed at the air outlet 13 of the drying device 1. The air guide portion 9 may allow the air flow to flow to the drying area to dry the clothes located in the drying area. Specifically, the air guide portion 9 may be connected to a rotating shaft. The rotating shaft may be connected to a motor, and the air guide portion 9 may be driven by the motor to rotate, thereby changing the direction of the air flow and guiding the air flow to flow to the drying area. Furthermore, the air guide portion 9 may further include swing blades, and on the basis of the air guide portion 9 rotating with the rotating shaft as the rotating shaft, the air guide portion 9 may guide the air flow to flow in multiple directions by changing the swinging direction of the swing blades.

[0094] Furthermore, when the drying device 1 turns on the drying mode, the positioning tag 7 can transmit pulses by frequency to measure the distance with the receiving device 8 set in the bathroom, so as to determine the range of the drying area and the position of the drying device 1. When the control device 4 receives the range signal of the drying area, it can automatically identify the actual position of the hanging part 21, thereby controlling the air guide part 9 to make the heated air flow flow to the drying area. In other words, although the hanging part 21 is not connected to the drying device 1, the user can place the hanging part 21 at any position in the bathroom, and can adjust the working state of the air guide part 9 by detecting the drying area, so that the heated air flow flows to the drying area. That is, it can be blown accurately to the area that needs to be dried, and the direction of the air flow can be intelligently controlled. Then, by setting a humidity sensor 3 on the drying device 1 or a pressure sensor 5 on the hanging device 2, the degree of drying can be automatically detected, the drying time can be controlled, and energy saving and intelligent drying can be achieved, thereby improving the convenience of use.

[0095] Furthermore, the positioning tag 7 is movably arranged on the hanging part 21, that is, the user can freely adjust the distance between the two positioning tags 7 according to the amount of clothes to be dried, thereby adjusting the range of the drying area, so as to further save electricity. Furthermore, in the above-mentioned first embodiment and second embodiment, a positioning device can also be provided to determine the positioning signal of the hanging device 2. The control device 4 can determine the drying area based on the positioning signal, and control the guide part based on the drying area to guide the airflow to the drying area to dry the clothes located in the drying area, so that the position of the hanging device 2 can be automatically identified, so that the user can move the hanging device 2 conveniently, and the airflow can be blown to the drying area more accurately, thereby avoiding the waste of electricity caused by the airflow blowing to the non-drying area, and achieving the purpose of effectively avoiding the waste of electricity and improving the convenience of use.
