Description

Technical Field

[0001] This application relates to the technical field of clothes drying racks, and more specifically, to a method, system, clothes drying rack, and storage medium for detecting the tilt of a clothes drying rack. Background Technology

[0002] With the development of technology, people's lives are becoming increasingly intelligent, and clothes drying racks, as home appliances, have become popular among consumers due to their convenience and practicality.

[0003] However, existing clothes drying racks often experience problems during use. Users tend to hang far more clothes on one side of the drying rod assembly than the other, leading to severe one-sided weight distribution and causing the drying rack to tilt. Alternatively, imbalances caused by the drying rod assembly's lifting and lowering mechanism can also cause it to tilt. Currently, existing clothes drying racks lack the ability to detect whether the drying rod assembly is tilted, thus affecting its normal operation. Summary of the Invention

[0004] This application provides a method, system, clothes dryer, and storage medium for detecting the tilt of a clothes dryer, which solves the technical problem that existing clothes dryers cannot detect whether the drying rod assembly is tilted, thus affecting the normal use of the clothes dryer.

[0005] In a first aspect, embodiments of this application provide a method for detecting the tilt of a clothes drying rack, comprising:

[0006] Acquire measurement distance; the measurement distance includes the distance measured by at least one set of distance measuring modules located at the bottom of the main unit assembly and / or the drying rod assembly of the clothes dryer; the measurement distance indicates the distance between the distance measuring module and the object located below it;

[0007] Based on the matching results of the measured distance and the reference distance, it is determined whether the drying rack assembly is tilted; the reference distance is obtained through one of the following:

[0008] Get the current descent height and distance of the drying rack assembly;

[0009] If the measured distance includes at least two distances measured by different ranging modules, then either distance is determined as the reference distance.

[0010] In one possible implementation, with the ranging module located at the bottom of the main unit, the drying rod assembly is provided with a mating part that mates with the ranging module in the vertical direction.

[0013] Based on the matching results of the measured distance and the reference distance, determine whether the drying rack assembly is tilted, including:

[0014] If the difference between the first distance and the height distance is within the preset first threshold range, then it is determined that the drying rack assembly is in a tilted state;

[0015] If the difference between the first distance and the distance between the installation position of the ranging module and the ground is within the preset second threshold range, then the drying rack assembly is determined to be in a horizontal state.

[0022] In one possible implementation, the drying rod assembly includes two parallel drying rods, a bracket connecting the two drying rods respectively, and end caps disposed at the ends of the drying rods;

[0023] If the difference between any non-reference distance and the reference distance in the measured distance is not within the preset fifth threshold range, then it is determined that the drying rack assembly is in a tilted state, including:

[0024] If the difference in horizontal distance between the installation positions of the non-reference distance and the reference distance measuring modules matches the width of the drying rack assembly, then it is determined that the drying rack assembly is tilted in the width direction.

[0025] If the difference in horizontal distance between the projection of the non-reference distance and the reference distance measurement module installation position is less than the width of the drying rack assembly, then the drying rack assembly is determined to be tilted in the length direction.

[0026] In one possible implementation, with the ranging module positioned at the bottom of the main unit, the measured distance includes a third distance generated based on the signal reflected back from the drying rack assembly when the signal emitted by the ranging module encounters it.

[0028] If the difference between the third distance and the height distance is not within the preset sixth threshold range, it is determined that the drying rack assembly is in a tilted state;

[0029] If the difference between any non-reference distance in the third distance and the reference distance is not within the preset seventh threshold range, then the drying rack assembly is determined to be in a tilted state.

[0030] In one possible implementation, the clothes drying rack tilt detection method also includes:

[0031] If it is determined that the drying rack assembly is tilted, the drying rack assembly is controlled to perform operations related to anti-tilt, and / or, a prompt message related to the tilt status is issued.

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0059] See Figure 1 As shown in the diagram, this application provides a structural schematic of a first type of clothes drying rack. This clothes drying rack is an application product of the clothes drying rack tilt detection method of this application embodiment. The clothes drying rack includes the clothes drying rack tilt detection system of this application embodiment.

[0060] See Figure 2 As shown in the diagram, this application provides a control structure block diagram of a main controller 111 controlling the movement of a drying rack assembly 140 based on the measured distance of a ranging module 130. The main controller 111 is electrically connected to a motor 150, which is configured to drive the drying rack assembly 140 to move under the control of the main controller 111. The main controller 111 can control the movement of the motor 150 according to the measured distance of the ranging module 130.

[0061] This application also provides a clothes drying rack tilt detection system, including a distance measuring module 130 and a main controller 111. The distance measuring module 130 is disposed at the bottom of the main unit assembly 110 and / or the drying rod assembly 140 of the clothes drying rack, and is used to detect the distance between the distance measuring module 130 and an object located below it; the main controller 111 is configured to execute the steps of the clothes drying rack tilt detection method of this application embodiment.

[0062] See Figure 1 As shown in the figure, this application embodiment also provides a clothes drying rack, including: a control system for the clothes drying rack of this application embodiment. The clothes drying rack includes: a main unit assembly 110, a telescopic bracket assembly 120, and a drying rod assembly 140. The main unit assembly 110 includes a main controller 111, which is wired or wirelessly connected to a ranging module 130. In the figure, the ranging module 130 is not shown. The ranging module 130 can transmit a first signal and / or receive a second signal, the first signal and / or the second signal including an infrared signal 131.

[0063] Specifically, one end of the telescopic bracket assembly 120 is fixedly connected to the main unit assembly 110, and the other end of the telescopic bracket assembly 120 is fixedly connected to the drying rod assembly 140. The telescopic bracket assembly 120 is a telescopic structure. The steel wire rope of the clothes drying machine extends or retracts under the drive of the motor 150 to drive the drying rod assembly 140 to move up and down. The telescopic bracket assembly 120 contracts and extends synchronously with the movement of the drying rod assembly 140.

[0064] Optionally, the motor 150 is fixedly connected to the main unit 110, and the motor 150 is connected to the drying rod assembly 140 through a rigid connector. The motor 150 controls the movement of the drying rod assembly 140 by controlling the retraction and extension of the rigid connector.

[0065] See Figure 3 As shown in the diagram, this application provides a structural schematic of a second type of clothes drying rack. Figure 3 As shown, when the ranging module 130 is installed at the bottom of the main unit 110, the drying rod assembly 140 is provided with a mating part 141 that cooperates with the ranging module 130 in the vertical direction.

[0066] The measured distance includes the distance measured by the ranging module 130 and the mating part 141.

[0067] See Figure 4 As shown, this application provides an embodiment of a method. Figure 1 A partial structural diagram showing the first and second signals of the clothes drying rack passing through through-hole 1411. See also... Figure 5 As shown, this application provides an embodiment of a method. Figure 1 The diagram shows a partial structural representation of a second signal reflected from the clothes drying rack assembly 140 when the clothes drying rack is tilted, causing the through hole 1411 to shift.

[0068] Combination Figure 1 , Figure 4 and Figure 5 As shown, the mating part 141 includes a through hole 1411; when the drying rod assembly 140 is in a horizontal state, the signal transceiver end of the ranging module 130 is directly opposite the through hole 1411 in the vertical direction; when the drying rod assembly 140 is in an inclined state, the signal transceiver end of the ranging module 130 is misaligned with the through hole 1411 in the vertical direction.

[0069] Optionally, when the angle between the clothes drying rod assembly 140 and the horizontal plane is not greater than a predetermined angle, both the first and second signals pass through the through hole 1411, and the signal transceiver of the ranging module 130 is vertically aligned with the through hole 1411. When the angle between the clothes drying rod assembly 140 and the horizontal plane is greater than the predetermined angle, the clothes drying rod assembly 140 tilts, the signal transceiver of the ranging module 130 is vertically misaligned with the through hole 1411, and the clothes drying rod assembly 140 reflects the second signal back, thus shortening the measurement distance. The tilting of the clothes drying rod assembly 140 means that the clothes drying rack is in a tilted state, at which point the angle between the clothes drying rod assembly 140 and the horizontal plane is greater than the predetermined angle.

[0070] This embodiment of the application utilizes a structure combining a ranging module 130 and a through hole 1411. When the clothes drying rod assembly 140 is horizontal, the signal transceiver of the ranging module 130 and the through hole 1411 are vertically aligned. When the clothes drying rod assembly 140 is tilted, the signal transceiver of the ranging module 130 and the through hole 1411 are vertically misaligned. This allows for the detection of whether the clothes drying rack is tilted based on whether the clothes drying rod assembly 140 is horizontal or tilted. Therefore, by setting the structure of the ranging module 130 and the through hole 1411, this embodiment of the application can detect whether the clothes drying rack is tilted, facilitating users to promptly address tilting caused by factors such as unbalanced loads and ensuring the normal operation of the clothes drying rack.

[0071] Optionally, the ranging module 130 includes an infrared transmitting unit for transmitting a first signal and an infrared receiving unit for receiving a second signal. The first signal includes an infrared signal 131, and the second signal includes an infrared signal 131. The infrared transmitting unit and the infrared receiving unit are signal transceivers of the ranging module 130.

[0072] Optionally, the measured distance can indicate whether the first signal emitted by the ranging module 130 passes through the through hole 1411 and is reflected back from the ground, or whether the clothes dryer is tilted, causing the position of the through hole 1411 to shift, resulting in the first signal failing to pass through the through hole 1411 and being reflected back from the drying rod assembly 140. If the drying rod assembly 140 is tilted, the first signal is reflected upon encountering the drying rod assembly 140, and the measured distance will be shorter, thus determining whether the first signal passes through the through hole 1411, and consequently determining whether the clothes dryer is tilted.

[0073] See Figure 4 and Figure 5 As shown, the drying rod assembly 140 includes two parallel drying rods 142, a bracket 143 connecting the two drying rods 142 respectively, and an end cap 144 disposed at the end of the drying rods 142.

[0074] Optionally, a through hole 1411 is formed on the bracket 143. There is one through hole 1411, which is elongated and extends along the direction of the bracket 143. The two ends of the through hole 1411 are arc-shaped, or semi-circular.

[0075] In some embodiments, the ranging module 130 includes a signal transmitter disposed toward the mating member 141; the mating member 141 includes a signal receiver disposed toward the signal transmitter, connected to the main controller 111, for receiving signals from the signal transmitter.

[0076] Optionally, the signal receiver can be connected to the main controller 111 via an electrical connection or a wired communication connection. In practical applications, a wireless communication connection can also be used.

[0077] In this embodiment, distance measurement can be performed by setting the signal transmitter and signal receiver on the host assembly 110 and the drying rod assembly 140 respectively, instead of setting the through hole 1411 on the drying rod assembly 140.

[0078] Optionally, the ranging principle of this application embodiment can be based on the principle of infrared ranging. The infrared emitting unit can be an emitting diode of infrared signal 131, and the infrared receiving unit 1312 can be a receiving diode of infrared signal 131. The emitting diode emits an infrared signal 131 of a specific frequency, and the receiving diode receives the infrared signal 131 of this frequency. When the detection direction of the infrared signal 131 encounters an obstacle, the infrared signal 131 is reflected back and received by the receiving diode.

[0079] Optionally, the main controller 111 is electrically connected to both the infrared emitting unit 1311 and the infrared receiving unit 1312. The main controller 111 can supply power to the infrared emitting unit 1311 via a control power signal, that is, output a constant predetermined voltage to the infrared emitting unit 1311. The main controller 111 can control the timing of infrared emitting unit 1311 emitting infrared rays according to the transmission information.

[0080] Optionally, the ranging module 130 can generate reflection information based on the second signal reflected back from the first signal when it encounters an obstacle, and send the reflection information to the main controller 111. Then, the main controller 111 can determine the measurement distance based on the reflection information.

[0081] The ranging module 130 can also determine distance information to represent the measured distance based on the first signal and the second signal, and send the distance information to the main controller 111 so that the main controller 111 can obtain the measured distance based on the distance information.

[0082] As an example, the main controller 111 is configured to control the infrared emitting unit 1311 to emit a first signal based on the emission information, and to determine the measurement distance based on the reflection information, the emission information, and the propagation speed of the first signal; the emission information includes the emission time of the first signal, and the reflection information includes the reception time of the first signal. Similarly, the main controller 111 can also determine the measurement distance based on the reflection information, the reception time of the emission information, and the propagation speed of the first signal.

[0083] In practical applications, the ranging module 130 generally utilizes the principle of non-diffusion during the propagation of infrared signal 131, that is, the refractive index of infrared signal 131 is very small when it passes through other materials. Therefore, long-distance ranging modules 130 will take infrared signal 131 into account. However, the propagation of infrared signal 131 takes time. When infrared signal 131 is emitted from the ranging module 130, hits a reflective object, is reflected back, and is received, the distance can be calculated based on the time from the emission of infrared signal 131 to its reception and the propagation speed of infrared signal 131.

[0084] In other embodiments, the measurement distance can also be determined based on the intensity of the reflected light from the second signal. The ranging module 130 can employ an infrared sensor. The basic principle of infrared sensor ranging is that an infrared LED emits an infrared signal 131, and a photosensitive receiver receives the reflected light from an object in front. The distance to the object can be determined based on the intensity of the reflected light. The principle of distance measurement using the ranging module 130 is that the light intensity received by the infrared receiver varies with the distance to the reflecting object; closer objects have stronger reflected light, and farther objects have weaker reflected light. Similarly, other devices that can determine the measurement distance based on obstacle reflection and their ranging principles can be applied to the clothes drying rack tilt detection system of this application embodiment.

[0085] See Figure 6 As shown in the diagram, this application provides a structural schematic of a third type of clothes drying rack. Figure 6 As shown, two ranging modules 130 are arranged as a group at the bottom of the drying rod assembly 140. The measuring distances measured by the two ranging modules 130 can be obtained respectively. If the deviation between the two measuring distances exceeds a predetermined threshold, it can be determined that the drying rod assembly 140 is tilted.

[0086] In practical applications, at least two ranging modules 130 can be installed at the bottom of the drying rod assembly 140. There can be two ranging modules 130 or more ranging modules 130, depending on the actual application requirements.

[0087] The main controller 111 may be a CPU (Central Processing Unit), a general-purpose processor, a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or other programmable logic devices, transistor logic devices, hardware components, or any combination thereof. It can implement or execute the various exemplary logic blocks, modules, and circuits described in conjunction with the disclosure of this application. The main controller 111 may also be a combination that implements computing functions, such as including one or more microprocessor combinations, a combination of a DSP and a microprocessor, etc.

[0088] See Figure 7 As shown, this application embodiment provides a flowchart of a method for detecting the tilt of a clothes drying rack. The method includes steps S701 to S702.

[0089] S701, Obtain the measurement distance; the measurement distance includes the distance measured by at least one set of distance measuring modules 130 disposed at the bottom of the main unit assembly 110 and / or the drying rod assembly 140 of the clothes dryer; the measurement distance indicates the distance between the distance measuring module 130 and the object located below it.

[0090] Optionally, at least one ranging module 130 may be disposed separately at the bottom of the main unit 110, separately at the bottom of the drying rod assembly 140, or at least one ranging module 130 may be disposed at the bottom of both the main unit 110 and the bottom of the drying rod assembly 140.

[0091] S702. Based on the matching result of the measured distance and the reference distance, determine whether the drying rod assembly 140 has tilted; the reference distance is obtained by one of the following: obtaining the current descent height of the drying rod assembly 140; if the measured distance includes at least two distances measured by different ranging modules 130, then either distance is determined as the reference distance.

[0092] Optionally, the reference distance can be the current descent height of the drying rod assembly 140, that is, the descent height of the drying rod assembly 140 from its upper limit position. The current descent height of the drying rod assembly 140 can be the height distance directly obtained by controlling the movement of the drying rod assembly 140 by the clothes dryer, or it can be obtained by acquiring the Hall signal output by the Hall sensor and determining the height distance based on the Hall signal; wherein, the Hall sensor is located in the motor of the clothes dryer.

[0093] Optionally, the current descent distance of the drying rod assembly 140 can also be determined based on the Hall signal output by the Hall sensor, thereby enabling real-time detection of the movement distance of the drying rod assembly 140. The main controller can also calculate the height distance based on the average motor speed multiplied by the running time.

[0094] Alternatively, the reference distance can be determined by specifying any one of the distances when the measured distance includes at least two distances measured by different ranging modules 130. That is, the reference distance is the distance measured by another ranging module 130.

[0095] Optionally, the object located below the ranging module 130 can be the drying rack assembly 140 and / or the ground. For example, in one case, when the ranging module 130 is positioned at the bottom of the main unit assembly, the object below the ranging module 130 can be the drying rack assembly, and the distance measured by the ranging module 130 can indicate the current descent height of the drying rack assembly 140 (i.e., the distance from the upper limit position). In another case, when the ranging module 130 is positioned at the bottom of the drying rack assembly 140, the object below the ranging module can be the ground, and the distance measured by the ranging module 130 can indicate the distance of the drying rack assembly 140 from the ground.

[0096] This application embodiment can obtain a measured distance by at least one set of ranging modules 130 deployed at the bottom of the main unit 110 and / or the drying rod assembly 140 of the clothes dryer. The measured distance can indicate the distance between the ranging module 130 and the object located below it. The reference distance can be obtained by obtaining the current descent height of the drying rod assembly 140 and / or, if the measured distance includes at least two distances measured by different ranging modules 130, then any one of these distances can be determined as the reference distance. Based on this, the matching result between the measured distance and the reference distance can be used to determine whether the drying rod assembly 140 is tilted. Therefore, the implementation of this application, based on the matching result of the distance measured by at least one set of ranging modules 130 and the reference distance, can detect whether the clothes dryer is tilted, facilitating timely resolution of the clothes dryer's tilt problem and ensuring the normal use of the clothes dryer.

[0097] See Figure 3 As shown, when the ranging module 130 is installed at the bottom of the main unit assembly 110, the drying rod assembly 140 is provided with a mating part 141 that cooperates with the ranging module 130 in the vertical direction; the measured distance includes the distance measured by the ranging module 130 and the mating part 141.

[0098] Optionally, the distance measured by the ranging module 130 and the mating part 141 can be the distance between the ranging module 130 and the mating part 141 (i.e., the current descent height of the drying rod assembly 140), or it can be the distance between the ranging module 130 and the ground measured by the mating part 141.

[0099] See Figure 4 and Figure 5 As shown, the mating part 141 includes a through hole 1411; the measured distance includes a first distance generated based on a first signal emitted by the ranging module 130 and a second signal reflected back from an object located below it.

[0100] Optionally, the mating part 141 includes a through hole 1411, so that when the drying rod assembly 140 is in an inclined state, the object located below the ranging module 130 can be the drying rod assembly 140; when the drying rod assembly 140 is in a horizontal state, the object located below the ranging module 130 can be the ground.

[0101] In step S702, based on the matching result of the measured distance and the reference distance, it is determined whether the drying rod assembly 140 is tilted, including at least one of steps A1 to A2.

[0102] Step A1: If the difference between the first distance and the height distance is within the preset first threshold range, then it is determined that the drying rod assembly 140 is in an inclined state.

[0103] See Figure 3 As shown, the drying rod assembly 140 is in an inclined state. The first signal emitted by the ranging module 130 does not pass through the through hole 1411 and encounters the second signal reflected back by the drying rod assembly 140. The first distance is approximately equal to the height distance H1.

[0104] If the difference between the first distance H and the height distance H1 is within the preset first threshold range, then the first distance H is approximately equal to H1, and the drying rod assembly 140 is in an inclined state.

[0105] Optionally, the first threshold range is a numerical range used to compare whether the difference between the first distance H and the height distance H1 is small. When the first distance H is approximately equal to the height distance H1, that is, the difference between the first distance H and the height distance H1 is small, setting a first threshold range allows us to determine whether the difference between the first distance H and the height distance H1 is small, i.e., whether the first distance H is approximately equal to the height distance H1, based on whether the difference between the first distance H and the height distance H1 is within the first threshold range. Similarly, the principle of setting the other threshold ranges in the embodiments of this application is the same.

[0106] Step A2: If the difference between the first distance and the distance between the installation position of the ranging module 130 and the ground is within the preset second threshold range, then it is determined that the drying rod assembly 140 is in a horizontal state.

[0107] See Figure 3 As shown, the drying rod assembly 140 is in a horizontal state. The first signal emitted by the ranging module 130 passes through the through hole 1411 and encounters the second signal reflected back from the ground. The first distance H is theoretically approximately equal to the distance H2 between the installation position of the ranging module 130 and the ground.

[0108] If the first distance H and the distance H2 between the installation position of the ranging module 130 and the ground are within the preset second threshold range, then the first distance H is approximately equal to H2, and the drying rod assembly 140 is in a horizontal state.

[0109] In one application scenario, when the clothes drying rack is used abnormally, such as when it is heavily loaded on one side, the drying rod assembly 140 tilts, causing the through hole 1411 on the bracket 143 of the drying rod assembly 140 to shift. The first signal fails to reach the ground, which determines that it is used abnormally. The drying rod assembly 140 can be controlled to stop moving, and the alarm device can be activated to remind the user to deal with the problem in a timely manner and ensure the normal use of the clothes drying rack.

[0110] See Figure 3 As shown, the mating component 141 includes a signal receiver; the measured distance includes a second distance generated based on the time when the signal transmitter of the ranging module 130 transmits a third signal and the time when the signal receiver receives the third signal, the second distance being approximately equal to the height distance H2.

[0111] In step S702, based on the matching result of the measured distance and the reference distance, it is determined whether the drying rod assembly 140 is tilted, including at least one of steps B1 to B2.

[0112] Step B1: If the difference between the second distance and the height distance is not within the preset third threshold range, then it is determined that the drying rod assembly 140 is in an inclined state.

[0113] Since the mating component 141 includes a signal receiver, and the measured distance includes a second distance generated based on the time when the signal transmitter of the ranging module 130 transmits the third signal and the time when the signal receiver receives the third signal, then the second distance is approximately equal to the height distance H2.

[0114] Optionally, the third threshold range is a numerical range used to compare whether the second distance and the height distance H2 are relatively small. When the second distance is approximately equal to the height distance H2, i.e., the difference between the second distance and the height distance H2 is small, a third threshold range is set. This allows us to determine whether the difference between the second distance and the height distance H2 is small, i.e., whether the second distance is approximately equal to the height distance H1, based on whether the difference is within the third threshold range. If the difference between the second distance and the height distance H2 is not within the preset third threshold range, it indicates that the distance value deviation between the second distance and the height distance H2 is large, and it can be determined that the drying rod assembly 140 is in a tilted state.

[0115] Step B2: If the difference between any non-reference distance and the reference distance in the second distance is not within the preset fourth threshold range, then it is determined that the drying rod assembly 140 is in a tilted state.

[0116] If the difference between any non-reference distance and the reference distance in the second distance is not within the preset fourth threshold range, then the second distance measured by the ranging module 130 and the mating part 141 has a large deviation from the second distance or height distance measured by the other ranging module 130 and the mating part 141 as the reference distance, it can be determined that the drying rod assembly 140 is in an inclined state.

[0117] See Figure 6 As shown, when the ranging module 130 is installed at the bottom of the drying rod assembly 140, the determination of whether the drying rod assembly 140 is tilted is based on the matching result of the measured distance and the reference distance. This includes: if the difference between any non-reference distance and the reference distance in the measured distance is not within the preset fifth threshold range, then the drying rod assembly 140 is determined to be in a tilted state.

[0118] See Figure 6 As shown, the measuring distance of one ranging module 130 is H3, and the measuring distance of another ranging module 130 is H4. If H3 is a non-reference distance and H4 is a reference distance, and the difference between H3 and H4 is not within the preset fifth threshold range, it indicates that the deviation between H3 and H4 is large, and it can be determined that the drying rod assembly 140 is in an inclined state.

[0119] Combination Figure 4 and Figure 5 As shown, the drying rod assembly 140 includes two parallel drying rods 142, a bracket 143 connecting the two drying rods 142 respectively, and an end cap 144 disposed at the end of the drying rods 142.

[0120] If the difference between any non-reference distance and the reference distance in the measured distance is not within the preset fifth threshold range, then it is determined that the drying rod assembly 140 is in a tilted state, including at least one of steps C1 to C2.

[0121] Step C1: If the difference in distance between the installation position projection of the non-reference distance and the reference distance measuring module 130 in the horizontal direction matches the width of the drying rod assembly 140, then it is determined that the drying rod assembly 140 is tilted in the width direction.

[0122] Optionally, the difference in horizontal distance between the projections of the non-reference distance and the reference distance measuring modules 130 at their installation positions is matched with the width of the drying rod assembly 140. This can be achieved by placing two measuring modules 130 at either end of the drying rod 142, with the drying rod 142 remaining horizontal. If the difference between the non-reference distance and the reference distance is not within a preset fifth threshold range, it indicates that the drying rod assembly 140 is tilted. Further, based on the matching of the horizontal width distance projected by the measuring modules 130 with the width of the drying rod assembly 140 (i.e., the length of the drying rod 142), it is determined that the drying rod assembly 140 is tilted in the width direction (the direction perpendicular to the arrangement direction of the drying rod 142).

[0123] Step C2: If the difference in horizontal distance between the installation positions of the non-reference distance and the reference distance measuring module 130 is less than the width of the drying rod assembly 140, then it is determined that the drying rod assembly 140 is tilted in the length direction.

[0124] Optionally, the difference in horizontal distance between the projections of the non-reference distance and the reference distance between the installation positions of the ranging modules 130 is less than the width of the drying rod assembly 140. This can be achieved by having two ranging modules 130 along both ends of the drying rod assembly 140. If the difference between the non-reference distance and the reference distance is not within a preset fifth threshold range, it indicates that the drying rod assembly 140 is tilted. If, further, the difference in horizontal distance between the projections of the non-reference distance and the reference distance between the installation positions of the ranging modules 130 is less than the width of the drying rod assembly 140, it indicates that the drying rod 142 is not horizontal, thus confirming that the drying rod assembly 140 is tilted in the length direction.

[0125] In some embodiments, when the ranging module 130 is positioned at the bottom of the main unit 110, the measured distance includes a third distance generated based on the signal reflected back from the drying rod assembly 140 when the signal emitted by the ranging module 130 is encountered. That is, the ranging module 130 needs to measure the distance between itself and the drying rod assembly 140, and the third distance is the distance between the ranging module 130 and the drying rod assembly 140, which is theoretically approximately equal to the height distance.

[0126] In step S702, based on the matching result of the measured distance and the reference distance, it is determined whether the drying rod assembly 140 is tilted, including at least one of steps D1 to D2.

[0127] Step D1: If the difference between the third distance and the height distance is not within the preset sixth threshold range, then it is determined that the drying rod assembly 140 is in an inclined state.

[0128] If the difference between the third distance and the height distance is not within the preset sixth threshold range, it indicates that the deviation between the third distance and the height distance is large, and it can be determined that the drying rod assembly 140 is in a tilted state.

[0129] Step D2: If the difference between any non-reference distance and the reference distance in the third distance is not within the preset seventh threshold range, then it is determined that the drying rod assembly 140 is in a tilted state.

[0130] At least two ranging modules 130 can be set at the bottom of the main unit 110. Each ranging module 130 measures a third distance. The third distance of one ranging module 130 is used as the reference distance, and the third distances of the other ranging modules 130 are non-reference distances. If the difference between any non-reference distance and the reference distance is not within the preset seventh threshold range, it indicates that the deviation between the third distances measured by at least two ranging modules 130 is large, and it can be determined that the drying rod assembly 140 is in a tilted state.

[0131] In some embodiments, the clothes drying rack tilt detection method further includes: if it is determined that the drying rod assembly 140 is tilted, controlling the drying rod assembly 140 to perform an operation related to anti-tilt, and / or issuing a prompt message related to the tilt state.

[0132] Optionally, anti-tilt related operations include controlling the drying rod assembly 140 to remain stationary, or controlling the leveling mechanism of the clothes dryer to perform corresponding leveling operations.

[0133] Optionally, the prompts related to the tilt status include alarm information, and the clothes dryer tilt detection system also includes an alarm device. The alarm device is connected to the main controller 111. The main controller 111 is configured to send alarm information to the alarm device when it determines that the clothes dryer is tilted. The alarm device is configured to receive the alarm information sent by the main controller 111 and trigger an alarm based on the alarm information. The alarm can be triggered by voice prompts, a buzzer sound, or displayed text, etc.

[0134] Optionally, the alarm device can be connected to the main controller 111 via an electrical connection or a wired communication connection. In practical applications, a wireless communication connection can also be used.
