Description

Technical Field

[0001] The present invention relates to the technical field of clothes drying, and particularly to a control method for a clothes dryer and a clothes dryer. Background Art

[0002] For current electric clothes dryers, the clothes drying rod can not only stop at the lowest position and the highest position, but also stop at any intermediate position between the lowest position and the highest position. For the position detection of the clothes drying rod, some are detected by a ranging module. By setting a reflector on the clothes drying rod, the ranging module measures the position of the clothes drying rod by transmitting a signal to the reflector and receiving the signal reflected by the reflector. However, the signal emitted by the ranging module is easily blocked by foreign objects, resulting in inaccurate detection. Some detect the number of turns of the wire reel rotation through a Hall sensor. The wire reel rotates forward and backward, and then calculates the moving distance of the wire rope according to the length of the wire rope on each turn of the wire reel. The components involved are numerous and the calculation is complex. Summary of the Invention

[0003] The purpose of the present invention is to provide a control method for a clothes dryer and a clothes dryer to solve the technical problems of inaccurate detection of the number of turns of the wire rope and complex detection existing in the prior art.

[0004] With the above concept, the technical solution adopted by the present invention is as follows:

[0005] A control method for a clothes dryer includes:

[0006] The emitting part of the detection component emits light towards the wire groove of the wire reel;

[0007] The controller obtains the signal of the receiving part of the detection component. If the receiving part does not receive light, it is determined that there is a lifting rope in the corresponding wire groove. If the receiving part receives light, it is determined that there is no lifting rope in the corresponding wire groove;

[0008] The controller determines the number of turns of the lifting rope on the wire reel according to the signal of the receiving part.

[0009] Wherein, if the number of turns of the lifting rope on the wire reel is greater than or equal to the first set value, or the number of turns of the lifting rope on the wire reel is less than or equal to the second set value, a first prompt message is sent and the wire reel is controlled to stop rotating.

[0010] Wherein, if the number of turns of the lifting rope on the wire reel is less than the first set value and greater than or equal to the third set value, or the number of turns of the lifting rope on the wire reel is greater than the second set value and less than or equal to the fourth set value, a second prompt message is sent and the rotation speed of the wire reel is controlled to drop to the lowest rotation speed.

[0011] Among them, when the clothes drying rod is in a static state, if the clothes dryer receives a lifting instruction, it first obtains the number of turns of the lifting rope on the wire winding wheel, and then controls the wire winding wheel to rotate.

[0012] Among them, before controlling the wire winding wheel to rotate, if the clothes drying rod is at the highest position and the clothes dryer receives an upward instruction, or if the clothes drying rod is at the lowest position and the clothes dryer receives a downward instruction, a first alarm message is sent.

[0013] Among them, two groups of detection components are arranged on the outer periphery of each wire winding wheel, and the two groups of detection components are evenly spaced in the circumferential direction of the wire winding wheel, and the number of turns of the lifting rope is judged according to the signals received by the two receiving parts.

[0014] Among them, the controller determines the position of the clothes drying rod according to the number of turns of the lifting rope on the wire winding wheel.

[0015] Among them, two wire winding wheels are provided. If the difference between the number of turns of the lifting ropes on the two wire winding wheels is greater than a first set threshold value, an inclination alarm message is sent.

[0016] A clothes dryer, comprising:

[0017] A clothes drying rod;

[0018] A lifting mechanism, comprising a wire winding wheel and a lifting rope wound around the wire winding wheel, the lifting rope is connected to the clothes drying rod, a plurality of wire grooves are arranged on the outer peripheral surface of the wire winding wheel, and the lifting rope is wound around the wire winding wheel and embedded in the wire grooves;

[0019] A detection component, comprising a transmitting part and a receiving part, the transmitting part and the receiving part are arranged at intervals along the tangent direction of the wire winding wheel and are distributed on both sides of the wire groove, the light emitted by the transmitting part faces the wire groove, the transmitting part and the receiving part both extend parallel to the axis of the wire winding wheel, and all the wire grooves are located within the detection field of view of the detection component.

[0020] Among them, a plurality of groups of the detection components are arranged, and the plurality of groups of the detection components are arranged at intervals in the circumferential direction of the wire winding wheel.

[0021] Advantages of the present invention:

[0022] For the control method of the clothes dryer proposed by the present invention, if there is no lifting rope in the wire groove, the light emitted by the transmitting part passes through the wire groove and is received by the receiving part. If there is a lifting rope in the wire groove, the light emitted by the transmitting part is blocked by the lifting rope and cannot pass through the wire groove, and the receiving part cannot receive the light; therefore, according to the signal of the receiving part, it can be judged whether the receiving part receives the light, and further, the number of turns of the lifting rope on the wire winding wheel can be judged; by directly detecting the wire groove to obtain whether there is a lifting rope in the wire groove, the detection is simpler and more direct, without light reflection, and the detection result is more accurate.

[0041] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0042] Embodiment 1

[0043] Refer to Figures 1 to 4 , an airer provided by an embodiment of the present invention includes a main body, a drying rod and a lifting mechanism. The drying rod is arranged below the main body; the lifting mechanism includes a winding wheel 10 and a lifting rope 20 wound around the winding wheel. The lifting rope 20 is connected to the drying rod. A plurality of winding grooves 11 are arranged on the outer peripheral surface of the winding wheel 10, and the lifting rope 20 is wound around the winding wheel 10 and embedded in the winding grooves 11.

[0044] The airer further includes a driving mechanism configured to drive the winding wheel 10 to rotate around a first axis to wind or lower the lifting rope 20. Wherein, the first axis can extend in the horizontal direction or in the vertical direction. The lifting rope 20 is wound around the winding wheel 10 for one layer. Since the lifting rope 20 is embedded in the winding grooves 11, the winding grooves 11 play a role in limiting the lifting rope 20, making the winding and lowering of the lifting rope 20 relatively stable.

[0045] The driving mechanism is used to drive the wire winding wheel 10 to rotate. It can be that the driving mechanism includes a motor and a speed reduction mechanism. The motor is arranged at the input end of the speed reduction mechanism, and the wire winding wheel 10 is arranged at the output end of the speed reduction mechanism. According to actual needs, first-stage reduction or second-stage reduction can be set. For example, the speed reduction mechanism includes a driving gear, a driven gear, and a transmission shaft. The driving gear is arranged on the motor shaft of the motor, the driven gear is arranged on the transmission shaft, the wire winding wheel 10 is connected to the transmission shaft, and the driving gear and the driven gear are engaged.

[0046] The clothes dryer further includes a detection component 30. The detection component 30 includes a transmitting part 31 and a receiving part 32. The transmitting part 31 and the receiving part 32 are arranged at intervals along the tangent direction of the wire winding wheel 10 and are distributed on both sides of the wire winding groove 11. The light emitted by the transmitting part 31 is directed towards the wire winding groove 11. Both the transmitting part 31 and the receiving part 32 extend parallel to the axis of the wire winding wheel 10, and all the wire winding grooves 11 are located within the detection field of view of the detection component 30.

[0047] If there is no lifting rope 20 in the wire winding groove 11, the light emitted by the transmitting part 31 passes through the wire winding groove 11 and is received by the receiving part 32. If there is a lifting rope 20 in the wire winding groove 11, the light emitted by the transmitting part 31 is blocked by the lifting rope 20 and cannot pass through the wire winding groove 11, and the receiving part 32 cannot receive the light. Therefore, according to whether the receiving part 32 can receive the light, it can be judged whether there is a lifting rope 20 in the wire winding groove 11.

[0048] Since both the transmitting part 31 and the receiving part 32 extend parallel to the first axis and all the wire winding grooves 11 are located within the detection field of view of the detection component 30, it is possible to judge whether there is a lifting rope 20 in each wire winding groove 11, and further judge the number of turns of the lifting rope 20 on the wire winding wheel 10. By directly detecting the wire winding groove 11 to obtain whether there is a lifting rope 20 in the wire winding groove 11, the detection is simpler and more direct, without light reflection, and the detection result is more accurate.

[0049] The light emitted by the transmitting part 31 can be infrared light or laser light. Therefore, the detection component 30 can be an infrared sensor or a laser sensor. The light emitting principle of the transmitting part 31 and the receiving principle of the receiving part 32 are conventional technologies and will not be elaborated here.

[0050] It can be understood that the clothes dryer further includes a controller. Components that need to be controlled, such as the driving mechanism and the detection component 30, are all electrically connected to the controller, and the controller can receive the signal of the receiving part 32. The controller can receive lifting and stop instructions to control the start and stop of the driving mechanism and realize the lifting of the clothes drying rod. The control principle of the controller is a conventional technology in the field of electric control and will not be elaborated here.

[0051] In this embodiment, the transmitting part 31 only needs to emit light along a straight line towards the wire winding groove 11 without setting an emission angle, so that the signals received by the receiving part 32 will not interfere with each other.

[0052] As an implementable manner, the emitting part 31 includes a plurality of emitters, which are arranged at intervals along the axial direction of the winding wheel 10, and one emitter is provided corresponding to each wire winding groove 11. The receiving part 32 includes a plurality of receivers, and the receivers are arranged in pairs with the emitters. For example, if N wire winding grooves 11 are provided on the outer peripheral surface of the winding wheel 10, then N pairs of emitters and receivers are provided. If N1 receivers can receive light, it is determined that the number of turns of the lifting rope 20 on the winding wheel 10 is N - N1.

[0053] As another implementable manner, the emitting part 31 is a grating emitter, and the grating emitter includes a plurality of light-emitting points, which are arranged at intervals along the direction parallel to the first axis. It can be understood that the receiving part 32 is a grating receiver, and the grating receiver can receive the signals of each light-emitting point.

[0054] It can be that one light-emitting point is provided corresponding to each wire winding groove 11. If N wire winding grooves 11 are provided on the outer peripheral surface of the winding wheel 10, then N light-emitting points are provided. If the grating receiver can receive N1 light rays, it is determined that the number of turns of the lifting rope 20 on the winding wheel 10 is N - N1. Along the tangent direction of the winding wheel 10, the light-emitting point is directly opposite to the center of the wire winding groove 11, so as to make the light emission more accurate.

[0055] It can also be that the light rays emitted by a plurality of light-emitting points are closely arranged along the axial direction of the winding wheel 10 to form a light curtain, and the extension length of the light curtain along the axial direction of the winding wheel 10 covers all the wire winding grooves 11. At this time, the number of light-emitting points is large and the distribution of the light-emitting points is relatively dense. For example, if there is a distance of length L where light can be received, according to the diameter of the wire winding groove 11, the number of wire winding grooves 11 within the length L can be determined as N2, and the total number of wire winding grooves 11 on the outer peripheral surface of the winding wheel 10 is N, then the number of turns of the lifting rope 20 on the winding wheel 10 is N - N2.

[0056] The detection assembly 30 further includes a first bracket 33 and a second bracket 34. The emitting part 31 is arranged on the first bracket 33, and the receiving part 32 is arranged on the second bracket 34. The first bracket 33 and the second bracket 34 provide a supporting function. The emitting part 31 and the receiving part 32 are detachable, which is convenient for installation and replacement.

[0057] The clothes dryer further includes a guide wheel. One end of the lifting rope 20 is connected to the winding wheel 10, and the other end of the lifting rope 20 extends downward around the guide wheel. The number of guide wheels can be set according to actual needs. The purpose of setting the guide wheel is to guide the lifting rope 20 so that the lifting rope 20 extends downward.

[0058] In this embodiment, there is a set of detection components 30, and the position of the detection components 30 is not restricted here. One end of the lifting rope 20 extending downward is usually connected to the clothes drying rod. By the detection components 30, the number of turns of the lifting rope 20 on the wire winding wheel 10 is judged. According to the data stored in the database of the controller, the position of the clothes drying rod corresponding to the number of turns can be retrieved.

[0059] The data stored in the database is obtained through multiple detections. The clothes drying rod can move between the highest position and the lowest position. When the clothes drying rod is at the highest position, the number of turns of the lifting rope 20 on the wire winding wheel 10 is N. When the clothes drying rod is at the lowest position, the number of turns of the lifting rope 20 on the wire winding wheel 10 is M. Since the total length of the lifting rope 20 is a fixed value, after determining the relative positions of the detection components 30, the wire winding wheel 10, and the lifting rope 20, through multiple detections, the corresponding relationship between the number of turns N of the lifting rope 20 on the wire winding wheel 10 and the position of the clothes drying rod can be recorded. For example, when the number of turns of the lifting rope 20 on the wire winding wheel 10 is N, the clothes drying rod is at the first position; when the number of turns of the lifting rope 20 on the wire winding wheel 10 is N - 1, the clothes drying rod is at the second position; and so on. Among them, the first position can be a fixed height value or a height range.

[0060] Embodiment Two

[0061] Figure 5 Embodiment Two is shown, in which the same or corresponding components as those in Embodiment One are labeled with the corresponding reference numerals of Embodiment One. For simplicity, only the differences between Embodiment Two and Embodiment One are described. The difference lies in that the detection components 30 further include a connecting portion 35. The connecting portion 35 is arranged between the first bracket 33 and the second bracket 34. The first bracket 33, the second bracket 34, and the connecting portion 35 are connected to form a U-shaped structure. By arranging both the transmitting portion 31 and the receiving portion 32 in the U-shaped structure, it is convenient to adjust the positions of the transmitting portion 31 and the receiving portion 32 so that they are facing each other. Then, the U-shaped structure is installed at a position corresponding to the wire winding wheel 10, so that the transmitting portion 31 and the receiving portion 32 are facing the wire winding groove 11, which is convenient for installation and disassembly without repeatedly adjusting the alignment of the transmitting portion 31 and the receiving portion 32.

[0062] Embodiment Three

[0063] Figure 6 to Figure 9 Embodiment Three is shown, in which the same or corresponding components as those in Embodiment One are labeled with the corresponding reference numerals of Embodiment One. For simplicity, only the differences between Embodiment Three and Embodiment One are described. The difference lies in that there are multiple sets of detection components 30, and the multiple sets of detection components 30 are arranged at intervals in the circumferential direction of the wire winding wheel 10. By arranging multiple sets of detection components 30, multiple positions in the circumferential direction of the wire winding wheel 10 are detected, improving the detection accuracy.

[0064] As Figure 6 and Figure 7 shown, two sets of detection components 30 are provided, and the two sets of detection components 30 are evenly distributed. By comparing the number of turns of the lifting rope 20 on the wire reel 10 detected by the two sets of detection components 30, the number of turns of the lifting rope 20 on the wire reel 10 can be accurately determined to half a turn. For the sake of convenience of description, taking the left-right direction in Figure 6 and Figure 7 as a reference, the detection component 30 on the right side is the first set of detection components 30, and the detection component 30 on the left side is the second set of detection components 30. When the number of turns of the lifting rope 20 on the wire reel 10 detected by the first set of detection components 30 is N1 and the number of turns of the lifting rope 20 on the wire reel 10 detected by the second set of detection components 30 is N1 + 1, as the lifting rope 20 is lowered, when the number of turns of the lifting rope 20 on the wire reel 10 detected by the first set of detection components 30 is N1 and the number of turns of the lifting rope 20 on the wire reel 10 detected by the second set of detection components 30 is N1, it means that the number of turns of the lifting rope 20 on the wire reel 10 has decreased by half a turn.

[0065] After determining the relative positions of the detection component 30, the wire reel 10, and the lifting rope 20, through multiple detections, the corresponding relationship between the number of turns of the lifting rope 20 on the wire reel 10 detected by each set of detection components 30 and the position of the clothes drying rod can be recorded. The relevant data can be stored in a database. When in use, the position of the corresponding clothes drying rod can be retrieved according to the number of turns of the lifting rope 20 on the wire reel 10 detected by each set of detection components 30. For example, when the number of turns of the lifting rope 20 on the wire reel 10 detected by the first set of detection components 30 is N1 and the number of turns of the lifting rope 20 on the wire reel 10 detected by the second set of detection components 30 is N2, the position of the clothes drying rod corresponding to N1 and N2 in the database is retrieved.

[0066] When multiple sets of detection components 30 are provided, the detection components 30 of each group can be evenly distributed or non-uniformly distributed.

[0067] As Figure 8 shown, three sets of detection components 30 are provided, and the three sets of detection components 30 are evenly distributed. By comparing the number of turns of the lifting rope 20 on the wire reel 10 detected by the three sets of detection components 30, the number of turns of the lifting rope 20 on the wire reel 10 can be accurately determined to 1 / 3 turn. Specifically, multiple detections can also be carried out to store the corresponding data and directly call it when in use.

[0068] When two sets of detection components 30 are provided, the two sets of detection components 30 can be independently set or connected to each other. As Figure 9As shown, there are two sets of detection components 30. The emitting parts 31 of one set of detection components 30 and the emitting parts 31 of the other set of detection components 30 are located on the same bracket. This simplifies the structure and reduces the number of components. Specifically, the two emitting parts 31 are arranged on the first bracket 33, and a second bracket 34 is provided corresponding to each receiving part 32.

[0069] Under the condition that the solutions do not conflict, the technical solutions of Embodiment 2 and Embodiment 3 can be combined.

[0070] See Figure 10 and Figure 11 , an embodiment of the present invention further provides a control method for a clothes dryer, including: the emitting part 31 of the detection component 30 emits light towards the wire groove 11 of the wire winding wheel 10; the controller obtains the signal of the receiving part 32 of the detection component 30. If the receiving part 32 does not receive light, it is determined that there is a lifting rope 20 in the corresponding wire groove 11. If the receiving part 32 receives light, it is determined that there is no lifting rope 20 in the corresponding wire groove 11; the controller determines the number of turns of the lifting rope 20 on the wire winding wheel 10 according to the signal of the receiving part 32.

[0071] If there is no lifting rope 20 in the wire groove 11, the light emitted by the emitting part 31 passes through the wire groove 11 and is received by the receiving part 32. If there is a lifting rope 20 in the wire groove 11, the light emitted by the emitting part 31 is blocked by the lifting rope 20 and cannot pass through the wire groove 11, and the receiving part 32 does not receive light; therefore, it is possible to determine whether the receiving part 32 receives light according to the signal of the receiving part 32, and further determine the number of turns of the lifting rope 20 on the wire winding wheel 10; by directly detecting the wire groove 11 to obtain whether there is a lifting rope 20 in the wire groove 11, the detection is simpler and more direct, without light reflection, and the detection result is more accurate.

[0072] In order to detect all the wire grooves 11, the emitting part 31 and the receiving part 32 are both arranged to extend parallel to the axis of the wire winding wheel 10, and all the wire grooves 11 are within the detection field of view of the emitting part 31 and the receiving part 32.

[0073] For a clothes dryer, the total length of the lifting rope 20 is certain. Therefore, the position of the clothes drying rod can be determined according to the number of turns of the lifting rope 20 on the wire winding wheel 10. There is a one-to-one correspondence between the number of turns of the lifting rope 20 on the wire winding wheel 10 and the position of the clothes drying rod. Therefore, after obtaining the number of turns of the lifting rope 20 on the current wire winding wheel 10, the position of the clothes drying rod corresponding to this number of turns can be retrieved according to the data stored in the database. The data stored in the database is obtained and stored through multiple detections.

[0074] It can be understood that if the clothes drying rod rises, the number of turns of the lifting rope 20 wound around the winding wheel 10 increases; if the clothes drying rod descends, the number of turns of the lifting rope 20 wound around the winding wheel 10 decreases. Therefore, if the number of turns of the lifting rope 20 wound around the winding wheel 10 increases, it is determined that the clothes drying rod rises; if the number of turns of the lifting rope 20 wound around the winding wheel 10 decreases, it is determined that the clothes drying rod descends.

[0075] In this embodiment, there is no need to provide proximity switches at the highest and lowest positions. By the cooperation of the transmitting part 31 and the receiving part 32, the number of turns of the lifting rope 20 wound around the winding wheel 10 is judged, and whether the clothes drying rod reaches the highest or lowest position is judged according to the number of turns.

[0076] If the number of turns of the lifting rope 20 wound around the winding wheel 10 is greater than or equal to the first set value, or if the number of turns of the lifting rope 20 wound around the winding wheel 10 is less than or equal to the second set value, a first prompt message is sent and the rotation of the winding wheel 10 is controlled to stop. Among them, the first prompt message can be "reached the highest position" or "reached the lowest position" displayed in text or broadcast by voice.

[0077] When the clothes drying rod rises close to the highest position, or when the clothes drying rod descends close to the lowest position, in order to avoid large vibrations caused by sudden stops at the end point, the moving speed of the clothes drying rod can be reduced before reaching the end point. Therefore, if the number of turns of the lifting rope 20 wound around the winding wheel 10 is less than the first set value and greater than or equal to the third set value, or if the number of turns of the lifting rope 20 wound around the winding wheel 10 is greater than the second set value and less than or equal to the fourth set value, a second prompt message is sent and the rotation speed of the winding wheel 10 is controlled to decrease to the lowest rotation speed. Among them, the second prompt message can be "approaching the end point" displayed in text or broadcast by voice.

[0078] It can be understood that during the process of controlling the rotation speed of the winding wheel 10 to decrease to the lowest rotation speed, if the current rotation speed of the winding wheel 10 is greater than the lowest rotation speed, the rotation speed of the winding wheel 10 is controlled to decrease, and in essence, the rotation speed of the motor is controlled to decrease; if the current rotation speed of the winding wheel 10 is already the lowest rotation speed, the rotation speed of the winding wheel 10 is controlled to remain unchanged.

[0079] When the clothes drying rod is in a stationary state, if the clothes dryer receives a lifting or lowering instruction, it first obtains the number of turns of the lifting rope 20 wound around the winding wheel 10, and then controls the winding wheel 10 to rotate. When about to switch from the stationary state to the moving state, before controlling the winding wheel 10 to rotate, by obtaining the current number of turns of the lifting rope 20 wound around the winding wheel 10, on the one hand, it can be checked whether the transmitting part 31 and the receiving part 32 are in normal working condition; on the other hand, the current position of the clothes drying rod can be judged.

[0080] Before controlling the rotation of the wire reel 10, if the drying rod is in the highest position and the drying machine receives an ascending instruction, or if the drying rod is in the lowest position and the drying machine receives a descending instruction, a first alarm message is issued. Among them, the first alarm message can be "Instruction error, unable to ascend or descend" displayed in text or broadcast by voice.

[0081] Specifically, refer to Figure 11 , when the drying rod is in a stationary state, if the drying machine receives a lifting or lowering instruction, first obtain the number of turns of the lifting and lowering rope 20 on the wire reel 10, determine the position of the drying rod according to the number of turns of the lifting and lowering rope 20 on the wire reel 10, and judge whether the drying rod is in the highest position. If so, then judge whether the instruction received by the drying machine is an ascending instruction. If not, then control the rotation of the wire reel 10; if the drying rod is in the highest position and the received instruction is an ascending instruction, a first alarm message is issued. If the drying rod is not in the highest position, then judge whether the drying rod is in the lowest position. If not, then control the rotation of the wire reel 10; if the drying rod is in the lowest position, then judge whether the instruction received by the drying machine is a descending instruction. If not, then control the rotation of the wire reel 10; if so, a first alarm message is issued.

[0082] When the drying rod is in a lifting or lowering state, if the drying machine receives a stop instruction, first control the wire reel 10 to stop rotating, and then obtain the number of turns of the lifting and lowering rope 20 on the wire reel 10.

[0083] In some embodiments, each time the drying machine receives a lifting or lowering instruction, the drying rod lifts or lowers a set distance. In some embodiments, the received lifting or lowering instruction is a set distance value. During the process of controlling the rotation of the wire reel 1, the number of turns of the lifting and lowering rope 20 on the wire reel 10 is obtained in real time, the position of the drying rod is determined according to the number of turns, and then the wire reel 10 is controlled to stop rotating in a timely manner.

[0084] In some embodiments, there are two wire reels 10, and a set of detection components 30 is provided corresponding to each wire reel 10. The inclination degree of the drying rod is judged according to the difference in the number of turns of the lifting and lowering ropes 20 on the two wire reels 10. If the difference in the number of turns of the lifting and lowering ropes 20 on the two wire reels 10 is greater than a first set threshold value, an inclination alarm message is issued.

[0085] In some embodiments, two sets of detection components 30 are provided on the outer periphery of each wire winding wheel 10. The two sets of detection components 30 are evenly spaced circumferentially around the wire winding wheel 10, and the number of turns of the lifting rope 20 is determined based on the signals received by the two receiving parts 32. That is, two sets of transmitting parts 31 and corresponding two sets of receiving parts 32 are provided on the outer periphery of each wire winding wheel 10. The two sets of transmitting parts 31 are evenly spaced circumferentially around the wire winding wheel 10, and the number of turns of the lifting rope 20 is determined based on the signals received by the two receiving parts 32. Since two sets of detection components 30 are provided, by comparing the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by the two sets of detection components 30, the number of turns of the lifting rope 20 on the wire winding wheel 10 is accurate to 1 / 2 turn.

[0086] When the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by the first set of detection components 30 is N1 and the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by the second set of detection components 30 is N1 + 1, as the lifting rope 20 is lowered, when the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by the first set of detection components 30 is N1 and the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by the second set of detection components 30 is N1, it means that the number of turns of the lifting rope 20 on the wire winding wheel 10 is reduced by 1 / 2 turn.

[0087] After determining the relative positions of the detection components 30 with respect to the wire winding wheel 10 and the lifting rope 20, through multiple detections, the corresponding relationship between the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by each set of detection components 30 and the position of the clothes drying rod can be recorded. The relevant data can be stored in a database. When in use, the position of the corresponding clothes drying rod is retrieved according to the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by each set of detection components 30. For example, when the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by the first set of detection components 30 is N1 and the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by the second set of detection components 30 is N2, the position of the clothes drying rod corresponding to N1 and N2 in the database is retrieved.

[0088] When multiple sets of detection components 30 are provided, the groups of detection components 30 can be evenly distributed or non-uniformly distributed. After determining the relative positions of the detection components 30 with respect to the wire winding wheel 10 and the lifting rope 20, through multiple detections, the corresponding relationship between the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by each set of detection components 30 and the position of the clothes drying rod can be recorded. The relevant data can be stored in a database. When in use, the position of the corresponding clothes drying rod is retrieved according to the number of turns of the lifting rope 20 on the wire winding wheel 10 detected by each set of detection components 30.

[0089] In some embodiments, three sets of detection components 30 are provided, and the three sets of detection components 30 are evenly distributed. By comparing the number of turns of the lifting rope 20 on the wire reel 10 detected by the three sets of detection components 30, the number of turns of the lifting rope 20 on the wire reel 10 can be accurately measured to 1 / 3 turn. Specifically, the corresponding data can also be stored by performing multiple detections and directly called when in use.

[0090] When the number of turns of the lifting rope 20 on the wire reel 10 detected by the first set of detection components 30 is N1, the number of turns of the lifting rope 20 on the wire reel 10 detected by the second set of detection components 30 is N1, and the number of turns of the lifting rope 20 on the wire reel 10 detected by the third set of detection components 30 is N1 + 1, as the lifting rope 20 is lowered, when the number of turns of the lifting rope 20 on the wire reel 10 detected by the first set of detection components 30 is N1, the number of turns of the lifting rope 20 on the wire reel 10 detected by the second set of detection components 30 is N1, and the number of turns of the lifting rope 20 on the wire reel 10 detected by the second set of detection components 30 is N1, it indicates that the number of turns of the lifting rope 20 on the wire reel 10 has decreased by 1 / 3 turn.

[0091] After determining the relative positions of the detection components 30, the wire reel 10, and the lifting rope 20, the corresponding relationship between the number of turns of the lifting rope 20 on the wire reel 10 detected by each set of detection components 30 and the position of the clothes drying rod can be recorded through multiple detections. The relevant data can be stored in a database. When in use, the position of the corresponding clothes drying rod can be retrieved according to the number of turns of the lifting rope 20 on the wire reel 10 detected by each set of detection components 30. For example, when the number of turns of the lifting rope 20 on the wire reel 10 detected by the first set of detection components 30 is N1, the number of turns of the lifting rope 20 on the wire reel 10 detected by the second set of detection components 30 is N2, and the number of turns of the lifting rope 20 on the wire reel 10 detected by the third set of detection components 30 is N3, the position of the clothes drying rod corresponding to N1, N2, and N3 in the database is retrieved.
