The main controller 111 can control the movement of the motor 150 according to the measured distance of the distance measuring module 130.

[0061] The embodiment of the present application also provides a clothes drying machine tilt detection system, comprising a distance measurement module 130 and a main controller 111. The distance measurement module 130 is arranged at the bottom of the main assembly 110 and / or the drying rod assembly 140 of the clothes drying machine, and is used to detect the distance between the distance measurement module 130 and the object located below it; the main controller 111 is configured to execute the steps of the clothes drying machine tilt detection method of the embodiment of the present application.

[0062] See also Figure 1 As shown, the embodiment of the present application also provides a clothes drying machine, including: a control system of the clothes drying machine of the embodiment of the present application. The clothes drying machine includes: a host component 110, a telescopic bracket component 120, and a clothes drying rod component 140. The host component 110 includes a main controller 111, and the main controller 111 is connected to the distance measuring module 130 by wired or wireless communication. In the figure, the distance measuring module 130 is not shown, and the distance measuring module 130 can transmit a first signal and / or receive a second signal, and the first signal and / or the second signal include an infrared signal 131.

[0063] Specifically, one end of the telescopic bracket assembly 120 is fixedly connected to the main 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, and the steel wire rope of the clothes drying machine is extended or retracted under the drive of the motor 150 to drive the drying rod assembly 140 to move up and down, and the telescopic bracket assembly 120 is synchronously contracted and extended with the movement of the drying rod assembly 140.

[0064] Optionally, the motor 150 is fixedly connected to the main unit assembly 110, and the motor 150 is connected to the drying rod assembly 140 via 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 also Figure 3 As shown, the present application embodiment provides a structural schematic diagram of a second type of clothes drying machine. Figure 3 As shown, when the distance measuring module 130 is arranged at the bottom of the main assembly 110 , a matching piece 141 which matches with the distance measuring module 130 in the vertical direction is arranged on the drying rod assembly 140 .

[0066] The measured distance includes the distance measured by the distance measuring module 130 and the matching component 141 .

[0067] See also Figure 4 As shown, the embodiment of the present application provides a Figure 1 The schematic diagram of the partial structure of the first signal and the second signal of the clothes drying machine passing through the through hole 1411 is shown. Figure 5 As shown, the embodiment of the present application provides a Figure 1 The diagram is a partial structural diagram of a second signal reflected from the drying rod assembly 140 without the first signal passing through the through hole 1411 when the clothes drying machine is in a tilted state causing the through hole 1411 to deviate.

[0068] Combination Figure 1 , Figure 4 and Figure 5 As shown, the matching piece 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 to the through hole 1411 in the vertical direction; when the drying rod assembly 140 is in a tilted 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 drying rod assembly 140 and the horizontal plane is not greater than a predetermined angle, both the first signal and the second signal pass through the through hole 1411, and the signal transceiver end of the distance measurement module 130 is vertically opposite to the through hole 1411. When the angle between the drying rod assembly 140 and the horizontal plane is greater than a predetermined angle, the drying rod assembly 140 tilts, the signal transceiver end of the distance measurement module 130 is vertically misaligned with the through hole 1411, and the drying rod assembly 140 reflects back the second signal, shortening the measured distance. The tilting of the drying rod assembly 140 means that the clothes drying machine is in a tilted state, and at this time, the angle between the drying rod assembly 140 and the horizontal plane is greater than the predetermined angle.

[0070] The embodiment of the present application can be based on the structure of the distance measuring module 130 combined with the through hole 1411. When the drying rod assembly 140 is in a horizontal state, the signal transceiver end of the distance measuring module 130 is directly opposite to 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 distance measuring module 130 is misaligned with the through hole 1411 in the vertical direction, so that the detection of whether the clothes drying machine is tilted can be realized according to whether the drying rod assembly 140 is in a horizontal state or an inclined state. Therefore, the embodiment of the present application can detect whether the clothes drying machine is in a tilted state by setting the structure of the distance measuring module 130 and the through hole 1411, so that the user can promptly solve the tilt of the clothes drying machine caused by reasons such as hanging weight on one side, and ensure the normal use of the clothes drying machine.

[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 transmitting and receiving ends of the ranging module 130.

[0072] Optionally, the measured distance can reflect whether the first signal emitted by the distance measurement module 130 passes through the through hole 1411 and then encounters the ground to reflect the second signal, or whether the clothes drying machine is in a tilted state, causing the position of the through hole 1411 to shift, and the first signal fails to pass through the through hole 1411, and encounters the drying rod assembly 140 to be reflected back as the second signal. When the drying rod assembly 140 is tilted, the first signal is reflected when it encounters the drying rod assembly 140, and the measured distance becomes shorter, so that it can be determined whether the first signal passes through the through hole 1411, and then whether the clothes drying machine is in a tilted state.

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

[0074] Optionally, the through hole 1411 is formed on the bracket 143. The number of the through hole 1411 is one, and the through hole 1411 is in the shape of an elongated strip and is arranged along the extending direction of the bracket 143. Both ends of the through hole 1411 are in the shape of an arc, which may be a semicircle.

[0075] In some embodiments, the ranging module 130 includes a signal transmitter arranged toward the matching piece 141; the matching piece 141 includes a signal receiver arranged toward the signal transmitter, connected to the main controller 111, and used to receive the signal from the signal transmitter.

[0076] Optionally, the signal receiver may be connected to the main controller 111 by electrical connection or wired communication connection. In practical applications, wireless communication connection may also be adopted.

[0077] In the embodiment of the present application, the distance can be measured by respectively setting a signal transmitter and a signal receiver on the host component 110 and the drying rod component 140, instead of setting a through hole 1411 on the drying rod component 140.

[0078] Optionally, the distance measurement principle of the embodiment of the present application can adopt the principle of infrared distance measurement. The infrared transmitting unit can be a transmitting diode of the infrared signal 131, and the infrared receiving unit 1312 can be a receiving diode of the infrared signal 131. The transmitting diode transmits the 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 the infrared emitting unit 1311 and the infrared receiving unit 1312, and the main controller 111 and the infrared emitting unit 1311 can control the power supply signal to supply power to the infrared emitting unit 1311, that is, output a constant predetermined voltage to the infrared emitting unit 1311. The main controller 111 can control the moment when the infrared emitting unit 1311 emits infrared rays according to the emission information.

[0080] Optionally, the distance measurement module 130 may generate reflection information based on a second signal reflected by an obstacle when the first signal encounters the obstacle, and send the reflection information to the main controller 111, and then the main controller 111 may determine the measurement distance based on the reflection information.

[0081] The distance measurement module 130 may also determine distance information representing the measured distance according to the first signal and the second signal, and send the distance information to the main controller 111, so that the main controller 111 acquires the measured distance based on the distance information.

[0082] As an example, the main controller 111 is configured to control the infrared transmitting unit 1311 to transmit the first signal according to the transmitting information, and determine the measured distance according to the reflection information, the transmitting information and the propagation speed of the first signal; the transmitting information includes the transmitting time of the first signal, and the reflection information includes the receiving time of the first signal. Similarly, the main controller 111 can also determine the measured distance according to the reflection information, the time of receiving the transmitting information and the propagation speed of the first signal.

[0083] In practical applications, the distance measurement module 130 generally utilizes the non-diffusion principle of the infrared signal 131 during propagation, that is, the refractive index of the infrared signal 131 is very small when passing through other substances, so the long-distance distance measurement module 130 will take the infrared signal 131 into consideration, and the propagation of the infrared signal 131 requires time. When the infrared signal 131 is emitted from the distance measurement module 130 and hits a reflective object, it is reflected back and received, and then the distance can be calculated based on the time from the emission to the reception of the infrared signal 131 and the propagation speed of the infrared signal 131.

[0084] In other embodiments, the measured distance can also be determined based on the intensity of the reflected light of the second signal. The ranging module 130 can use an infrared sensor. The basic principle of ranging of the infrared sensor is that the infrared light-emitting tube emits an infrared signal 131, and the photosensitive receiving tube receives the reflected light of the object in front. The distance of the object can be judged according to the intensity of the reflected light. The principle of using the ranging module 130 for distance measurement is that the intensity of light received by the infrared receiving tube varies with the distance of the reflecting object. The closer the distance, the stronger the reflected light, and the farther the distance, the weaker the reflected light. Similarly, other devices that can determine the measured distance based on obstacle reflection and their ranging principles can be applied to the clothes drying machine tilt detection system of the embodiment of the present application.

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

[0086] In actual applications, at least two ranging modules 130 can be arranged at the bottom of the clothes-drying rod assembly 140. There can be two ranging modules 130 or more ranging modules 130. The ranging modules 130 can be set according to actual application needs.

[0087] The main controller 111 can be a CPU (Central Processing Unit), a general 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 various exemplary logic blocks, modules and circuits described in conjunction with the disclosure of this application. The main controller 111 can also be a combination that implements computing functions, such as a combination of one or more microprocessors, a combination of a DSP and a microprocessor, etc.

[0088] See also Figure 7 As shown, the present application embodiment provides a flow chart of a method for detecting the inclination of a clothes drying machine. The method for detecting the inclination of a clothes drying machine includes: step S701 to step S702.

[0089] S701, obtaining a measured distance; the measured distance includes a distance measured by at least one set of distance measuring modules 130 arranged at the bottom of the main assembly 110 and / or the drying rod assembly 140 of the clothes drying machine; the measured distance indicates the distance between the distance measuring module 130 and an object located below it.

[0090] Optionally, at least one ranging module 130 can be separately arranged at the bottom of the host component 110 , or separately arranged at the bottom of the drying rod component 140 , or at least one ranging module 130 can be arranged at the bottom of the host component 110 and the bottom of the drying rod component 140 .

[0091] S702. Determine whether the clothes-drying rod assembly 140 is tilted based on the matching result between the measured distance and the reference distance; the reference distance is obtained by one of the following: obtaining the current descending height distance of the clothes-drying rod assembly 140; if the measured distance includes at least two distances measured by different distance measurement modules 130, any distance is determined as the reference distance.

[0092] Optionally, the reference distance may be the height distance currently dropped by the drying rod assembly 140, that is, the height distance dropped by the drying rod assembly 140 from the upper limit position. The height distance currently dropped by the drying rod assembly 140 may be the height distance directly obtained by the clothes drying machine controlling the movement of the drying rod assembly 140, or may be obtained by: obtaining a Hall signal output by a Hall sensor, and determining the height distance according to the Hall signal; wherein the Hall sensor is provided on the motor of the clothes drying machine.

[0093] Optionally, the height distance currently dropped by the drying rod assembly 140 can also be determined according to the Hall signal output by the Hall sensor, so that the height distance of the movement of the drying rod assembly 140 can be detected in real time. The main controller can also calculate the height distance according to the average speed of the motor multiplied by the running time.

[0094] Optionally, the reference distance may also be any distance determined as the reference distance when the measured distance includes at least two distances measured by different distance measurement modules 130 . That is, the reference distance is the distance measured by another distance measurement module 130 .

[0095] Optionally, the object below the distance measuring module 130 may be the drying rod assembly 140 and / or the ground. Exemplarily, in one case, when the distance measuring module 130 is arranged at the bottom of the host assembly, the object below the distance measuring module 130 may be the drying rod assembly, and the distance measured by the distance measuring module 130 may indicate the current descending height distance of the drying rod assembly 140 (i.e., the distance from the upper limit position). In another case, when the distance measuring module 130 is arranged at the bottom of the drying rod assembly 140, the object below the distance measuring module may be the ground, and the distance measured by the distance measuring module 130 may indicate the distance between the drying rod assembly 140 and the ground.

[0096] The embodiment of the present application can obtain the measured distance measured by at least one group of distance measuring modules 130 arranged at the bottom of the main unit component 110 and / or the drying rod component 140 of the clothes drying machine. The measured distance can indicate the distance between the distance measuring module 130 and the object located below it. The reference distance can be obtained by obtaining the height distance of the current descent of the drying rod component 140 and / or if the measured distance includes at least two distances measured by different distance measuring modules 130, then any distance is determined as the reference distance. On this basis, it can be determined whether the drying rod component 140 is tilted by matching the measured distance with the reference distance. Therefore, the implementation of the present application can detect whether the clothes drying machine is in a tilted state based on the distance measured by at least one group of distance measuring modules 130 and the matching result of the reference distance, so as to facilitate timely resolution of the tilt problem of the clothes drying machine and ensure the normal use of the clothes drying machine.

[0097] See also Figure 3 As shown, when the distance measuring module 130 is arranged at the bottom of the main unit assembly 110, a matching piece 141 is arranged on the drying rod assembly 140 to match the distance measuring module 130 in the vertical direction; the measured distance includes the distance measured by the distance measuring module 130 and the matching piece 141.

[0098] Optionally, the distance measured by the ranging module 130 and the matching component 141 can be the distance between the ranging module 130 and the matching component 141 (i.e., the current descending height distance of the clothes-drying rod assembly 140), or it can be the distance from the ground measured by the ranging module 130 based on the matching component 141.

[0099] See also Figure 4 and Figure 5 As shown, the matching piece 141 includes a through hole 1411; the measured distance includes a first distance generated according to a first signal emitted by the distance measuring module 130 and a second signal reflected back by an object located therebelow.

[0100] Optionally, the matching piece 141 includes a through hole 1411, and when the drying rod assembly 140 is in a tilted state, the object below the ranging module 130 may be the drying rod assembly 140; when the drying rod assembly 140 is in a horizontal state, the object below the ranging module 130 may be the ground.

[0101] In S702, based on the matching result between 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 a preset first threshold range, it is determined that the drying rod assembly 140 is in a tilted state.

[0103] See also Figure 3 As shown, the drying rod assembly 140 is in a tilted state, the first signal emitted by the distance measurement module 130 does not pass through the through hole 1411, and encounters the second signal reflected back by the drying rod assembly 140, and 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 a preset first threshold range, then the first distance H is approximately equal to H1, and the drying rod assembly 140 is in a tilted state.

[0105] Optionally, the first threshold range is a numerical range, which is 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, a first threshold range is set, and it can be determined whether the difference between the first distance H and the height distance H1 is small, that is, 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 principles for setting the remaining threshold ranges in the embodiments of the present application are consistent.

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

[0107] See also Figure 3 As shown, the clothes-drying rod assembly 140 is in a horizontal state, and the first signal emitted by the ranging module 130 passes through the through hole 1411 and encounters the second signal reflected back by 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 distance measuring module 130 and the ground are within a 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 machine is in abnormal use, such as severe one-sided weight hanging, the drying rod assembly 140 is tilted, causing the through hole 1411 on the bracket 143 of the drying rod assembly 140 to shift, and the first signal fails to reach the ground, it is determined that it is in abnormal use. The drying rod assembly 140 can be controlled to stop moving, and the alarm device can be controlled to sound an alarm to facilitate timely processing by the user to ensure normal use of the clothes drying machine.

[0110] See also Figure 3 As shown, the matching component 141 includes a signal receiver; the measured distance includes a second distance generated according to 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, and the second distance is approximately equal to the height distance H2.

[0111] In S702, based on the matching result between 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 a preset third threshold range, it is determined that the drying rod assembly 140 is in a tilted state.

[0113] Since the fitting 141 includes a signal receiver, the measured distance includes a second distance generated according to the time when the signal transmitter of the distance measurement 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, which is used to compare whether the second distance is smaller than the height distance H2. When the second distance is approximately equal to the height distance H2, that is, the difference between the second distance and the height distance H2 is smaller, a third threshold range is set, and it can be determined whether the difference between the second distance and the height distance H2 is smaller, that is, whether the second distance is approximately equal to the height distance H1, based on whether the difference between the second distance and the height distance H2 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 means 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 in the second distance and the reference distance is not within a preset fourth threshold range, it is determined that the drying rod assembly 140 is in a tilted state.

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

[0117] See also Figure 6 As shown, when the ranging module 130 is arranged at the bottom of the drying rod assembly 140, 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: if the difference between any non-reference distance in the measured distance and the reference distance is not within the preset fifth threshold range, it is determined that the drying rod assembly 140 is in a tilted state.

[0118] See also Figure 6 As shown, the measuring distance of one ranging module 130 is H3, and the measuring distance of the other 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 means that the deviation between H3 and H4 is large, and it can be determined that the drying rod assembly 140 is in a tilted state.

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

[0120] If the difference between any non-reference distance in the measured distance and the reference distance is not within the preset fifth threshold range, 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 distance difference between the installation positions of the distance measuring module 130 for measuring the non-reference distance and the reference distance in the horizontal direction matches the width of the drying rod assembly 140, it is determined that the drying rod assembly 140 is tilted in the width direction.

[0122] Optionally, the distance difference between the installation positions of the distance measuring module 130 for measuring the non-reference distance and the reference distance projected in the horizontal direction matches the width of the drying rod assembly 140, and two distance measuring modules 130 may be arranged at both ends of the drying rod 142, and the drying rod 142 remains in a horizontal state. If the difference between the non-reference distance and the reference distance is not within the preset fifth threshold range, it indicates that the drying rod assembly 140 is tilted, and further, according to the matching of the width distance projected in the horizontal direction by the distance measuring module 130 and 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 (a direction perpendicular to the arrangement direction of the drying rod 142).

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

[0124] Optionally, the difference in distance between the installation positions of the distance measuring modules 130 for measuring the non-reference distance and the reference distance in the horizontal direction is less than the width of the drying rod assembly 140, and the two distance measuring modules 130 may be at both ends of the drying rod assembly 140. If the difference between the non-reference distance and the reference distance is not within the preset fifth threshold range, it indicates that the drying rod assembly 140 is tilted. If the difference in distance between the installation positions of the distance measuring modules 130 for measuring the non-reference distance and the reference distance in the horizontal direction is less than the width of the drying rod assembly 140, it indicates that the drying rod 142 is not in a horizontal state, and it is determined that the drying rod assembly 140 is tilted in the length direction.

[0125] In some embodiments, when the distance measuring module 130 is arranged at the bottom of the host assembly 110, the measured distance includes a third distance generated according to the signal emitted by the distance measuring module 130 and the signal reflected back by the drying rod assembly 140. That is, the distance measuring module 130 needs to measure the distance between the distance measuring module 130 itself and the drying rod assembly 140, and the third distance is the distance between the distance measuring module 130 and the drying rod assembly 140, which is approximately equal to the height distance in theory.

[0126] In S702, based on the matching result between 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 a preset sixth threshold range, it is determined that the drying rod assembly 140 is in a tilted state.

[0128] If the difference between the third distance and the height distance is not within the preset sixth threshold range, it means 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 in the third distance and the reference distance is not within a preset seventh threshold range, 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 component 110, and each ranging module 130 measures a third distance. The third distance of one ranging module 130 is used as a reference distance, and the third distances of the remaining ranging modules 130 are non-reference distances. If the difference between any non-reference distance in the third distances and the reference distance is not within the preset seventh threshold range, it means 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 component 140 is in a tilted state.

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

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

[0133] Optionally, the prompt information related to the tilt state includes alarm information, and the clothes drying machine tilt detection system further includes: an alarm device. The alarm device is connected to the main controller 111. The main controller 111 is configured to send an alarm message to the alarm device when it is determined that the clothes drying machine is in a tilt state. The alarm device is configured to receive the alarm information sent by the main controller 111 and alarm according to the alarm information. The alarm method can be a voice prompt, a buzzer sound, a prompt text display, etc.

[0134] Optionally, the alarm device may be connected to the main controller 111 by electrical connection or wired communication connection. In practical applications, wireless communication connection may also be adopted.
