[0053] To make the objectives, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0054] See Figure 1 As shown, the embodiments of the present application provide a structural schematic diagram of a drying rack. The drying rack is an application product of the drying rack tilt detection system in the embodiments of the present application. The drying rack includes: the drying rack tilt detection system in the embodiments of the present application.

[0055] See Figure 2 As shown, the embodiments of the present application provide a structural framework diagram of the connection relationship between a main control board 111, a ranging module 130 and a motor 170. Several groups of ranging modules 130 are electrically connected to the main control board 111, the main control board 111 is electrically connected to the motor 170, and the motor 170 is configured to drive the drying rod assembly 140 to move (such as rising or falling) under the control of the main control board 111.

[0056] The embodiments of the present application provide a drying rack tilt detection system, including: a host component 110, several groups of ranging modules 130 and a drying rod assembly 140.

[0057] The host component 110 includes a main control board 111; several groups of ranging modules 130 are connected to the main control board 111, and at least one group of ranging modules 130 is arranged on the host component 110.

[0058] The drying rod assembly 140 includes at least one fitting, and the fitting cooperates with at least one group of ranging modules 130 arranged on the host component 110 in the vertical direction.

[0059] The embodiments of the present application are provided with several groups of ranging modules 130, all of which are connected to the main control board 111. At the same time, the drying rod assembly 140 includes at least one fitting, and the fitting cooperates with at least one group of ranging modules 130 provided on the host assembly 110 in the vertical direction. The measuring distance between the ranging module 130 and the object below it can be measured through the fitting and the ranging module 130, so that the main control board 111 can determine whether the drying rod assembly 140 is in a horizontal state or an inclined state. The embodiments of the present application provide a hardware implementation basis for detecting whether the clothes dryer is in an inclined state, solve the problem that the inclined state cannot be detected due to the lack of corresponding hardware configuration in the prior art, and can effectively ensure the normal use of the clothes dryer.

[0060] Optionally, the connection between several groups of ranging modules 130 and the main control board 111 can transmit data in the way of electrical connection or wired communication connection. In practical applications, a wireless communication connection between the ranging module 130 and the main control board 111 is also applicable.

[0061] Optionally, the ranging module 130 can be used to transmit the first signal and / or receive the second signal, generate reflection information according to the second signal, and send the reflection information to the main control board 111, so that the main control board 111 determines the measuring distance according to the reflection information.

[0062] The ranging module 130 can also determine the distance information representing the measuring 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 obtains the measuring distance based on the distance information.

[0063] See Figure 1 and Figure 2 As shown, the clothes dryer further includes a frame 160. The frame 160 and the host outer cover 121 are both fixedly connected. The motor 170 is arranged inside the frame 160, the motor 170 is fixedly connected to the host assembly 110, the motor 170 is connected to the drying rod assembly 140 through a rigid connecting piece, and the motor 170 controls the movement of the drying rod assembly 140 by controlling the retraction and extension of the rigid connecting piece.

[0064] Optionally, the frame 160 is a hidden frame, which can form an accommodating space for accommodating the drying rod assembly 140 and is applied to a hidden clothes dryer. At the same time, the frame 160 can also be applied to a conventional clothes dryer.

[0065] See Figure 3 As shown, the embodiments of the present application provide a Figure 1 Partial structural schematic diagram of the first signal and the second signal of the clothes dryer shown passing through the first through hole 144. See Figure 4 As shown, the embodiments of the present application provide a Figure 1Partial structural schematic diagram of the second signal reflected back from the drying rod assembly 140 when the first signal does not pass through the through hole due to the tilting of the drying rack shown.

[0066] Combined with Figure 3 and Figure 4 As shown, the fitting includes a first through hole 144. Among them, when the drying rod assembly 140 is in a horizontal state, the signal transceiver of the distance measuring module 130 is directly opposite to the first through hole 144 in the vertical direction; when the drying rod assembly 140 is in a tilted state, the signal transceiver of the distance measuring module 130 is misaligned with the first through hole 144 in the vertical direction.

[0067] Specifically, the signal transceiver of the distance measuring module 130 is used to send the first signal and receive the second signal.

[0068] 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 first through hole 144, the signal transceiver of the distance measuring module 130 is directly opposite to the first through hole 144 in the vertical direction, and the first signal passes through the first through hole 144 and is reflected by the ground. When the angle between the drying rod assembly 140 and the horizontal plane is greater than the predetermined angle, the drying rod assembly 140 is tilted, the signal transceiver of the distance measuring module 130 is misaligned with the first through hole 144 in the vertical direction, and the first signal is reflected back as the second signal when it encounters the drying rod assembly 140, resulting in a shorter measured distance.

[0069] Optionally, when the drying rod assembly 140 is tilted, that is, the drying rack is in a tilted state, at this time, the angle between the drying rod assembly 140 and the horizontal plane is greater than the predetermined angle.

[0070] In the embodiment of the present application, the fitting includes a first through hole 144. When the drying rod assembly 140 is in a horizontal state, the signal transceiver of the distance measuring module 130 is directly opposite to the first through hole 144 in the vertical direction; when the drying rod assembly 140 is in a tilted state, the signal transceiver of the distance measuring module 130 is misaligned with the first through hole 144 in the vertical direction. Thus, it is possible to detect whether the drying rack is tilted according to whether the drying rod assembly 140 is in a horizontal state or a tilted state. Therefore, by setting the structure of the distance measuring module 130 and the first through hole 144, the embodiment of the present application can detect whether the drying rack is in a tilted state, which is convenient for users to timely solve the tilt of the drying rack caused by reasons such as unilateral hanging weight, and ensure the normal use of the drying rack.

[0071] Optionally, the measured distance determined by the main control board 111 can reflect whether the first signal emitted by the ranging module 130 is the second signal reflected back by the ground after passing through the first through hole 144, or whether the position of the first through hole 144 is offset due to the tilting state of the drying rack, and the first signal fails to pass through the first through hole 144 and is reflected back by the drying rod assembly 140 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 will become shorter, so as to determine whether the first signal passes through the first through hole 144, and further determine whether the drying rack is in a tilted state.

[0072] See Figure 3 and Figure 4 As shown, the first through hole 144 is strip-shaped and arranged along the length direction of the component where the first through hole 144 is opened. Optionally, both ends of the first through hole 144 are arc-shaped, which can be semi-circular.

[0073] In some embodiments, the ranging module 130 includes a signal transmitter arranged towards the mating part. The mating part includes a signal receiver arranged towards the signal transmitter and is connected to the main control board 111 for receiving the signal of the signal transmitter.

[0074] Optionally, the drying rod assembly 140 further includes a sub-main control board. The signal receiver is electrically connected or wired communication-connected to the sub-main control board, and the sub-main control board is electrically connected or wired communication-connected to the main control board 111, so as to transmit the information of the signal receiver to the main control board 111, facilitating the main control board 111 to determine the measured distance. In practical applications, the sub-main control board and the main control board 111 can also be wirelessly communication-connected.

[0075] The embodiment of the present application also provides another embodiment for measuring the distance. Without setting a through hole, the ranging module 130 includes a signal transmitter arranged towards the mating part, and the mating part includes a signal receiver arranged towards the signal transmitter. The distance is measured by the time of infrared light propagating in the air, and then it can be determined whether the drying rod assembly 140 is tilted by measuring the distance.

[0076] See Figure 3 and Figure 4 As shown, the drying rod assembly 140 includes two drying rods 142 arranged in parallel, a bracket 143 connecting the two drying rods 142, and a scissors frame 141 connecting the host assembly 110 and the bracket 143; the mating part is arranged on the drying rod 142 and / or the bracket 143.

[0077] As an example, the measurement distances obtained by a ranging module 130 and a mating component can be compared with the measurement distances obtained by another ranging module 130 and a mating component. If the difference between the two measurement distances is within a first predetermined threshold range, the two measurement distances are the same and the drying rod assembly 140 does not tilt; if the difference between the two measurement distances is not within the first predetermined threshold range, there is a large deviation between the two measurement distances and the drying rod assembly 140 tilts.

[0078] Optionally, the first predetermined threshold range is a numerical range, which is used to compare whether the difference between the two measurement distances is small. When the two measurement distances are close to the same, that is, the difference between the two measurement distances is small, a first predetermined threshold range is set. It can be determined whether the difference between the two measurement distances is small, that is, whether the two measurement distances are equal, according to whether the difference between the two measurement distances is within the first predetermined threshold range. Conversely, if the two measurement distances are not within the first predetermined threshold range, there is a large deviation between the two measurement distances. Similarly, the principle of setting the remaining predetermined threshold ranges in the embodiments of the present application is the same.

[0079] See Figure 5 As shown, an embodiment of the present application provides a structural schematic diagram of a ranging module 130. As Figure 5 shown, the signal transmitting and receiving end of the ranging module 130 includes: an infrared transmitting unit 1311 and an infrared receiving unit 1312. The infrared transmitting unit 1311 is used to transmit a first signal, and the infrared receiving unit 1312 is used to receive a second signal. Combining Figure 3 and Figure 4 shown, the first signal includes an infrared signal 1313, and the second signal includes an infrared signal 1313.

[0080] Optionally, the ranging principle of the embodiments of the present application is the same as the principle of using infrared ranging. The infrared transmitting unit 1311 can be a transmitting diode of the infrared signal 1313, and the infrared receiving unit 1312 can be a receiving diode of the infrared signal 1313. The transmitting diode emits an infrared signal 1313 of a specific frequency, and the receiving diode receives this frequency of infrared signal 1313. When the detection direction of the infrared signal 1313 encounters an obstacle, the infrared signal 1313 is reflected back and received by the receiving diode.

[0081] Optionally, the main control board 111 is electrically connected to both the infrared transmitting unit 1311 and the infrared receiving unit 1312. The main control board 111 and the infrared transmitting unit 1311 can supply power to the infrared transmitting unit 1311 by controlling a power signal, that is, output a predetermined voltage to the infrared transmitting unit 1311. The main control board 111 can control the moment when the infrared transmitting unit 1311 emits infrared rays according to the emission information.

[0082] As an example, the main control board 111 is configured to control the infrared emission unit 1311 to emit a first signal according to the emission information, and determine the measurement distance according to 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 control board 111 can also determine the measurement distance according to the reflection information, the time of receiving 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 when the infrared signal 1313 propagates, that is, the refractive index of the infrared signal 1313 is very small when passing through other substances. Therefore, long-distance ranging modules 130 will all consider the infrared signal 1313, and the propagation of the infrared signal 1313 takes time. When the infrared signal 1313 is emitted from the ranging module 130, hits a reflector and is reflected back and received, the distance can be calculated based on the time from the emission of the infrared signal 1313 to its reception and the propagation speed of the infrared signal 1313.

[0084] In other embodiments, the measurement distance can also be determined according to the intensity of the reflected light of the second signal. The ranging module 130 can adopt an infrared sensor. The basic ranging principle of the infrared sensor is that the infrared light-emitting diode emits an infrared signal 1313, and the photosensitive receiving tube receives the reflected light from 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 light intensity received by the infrared receiving tube changes with the distance of the reflecting object. The closer the distance, the stronger the reflected light; the farther the distance, the weaker the reflected light. Similarly, other devices that can determine the measurement distance based on the reflection of obstacles and their ranging principles can all be applied to the clothes dryer tilt detection system of the embodiments of the present application.

[0085] In some embodiments, the host component 110 includes a host outer cover 121; the ranging module 130 is located inside the host outer cover 121; the host outer cover 121 is provided with a second through hole 1211 that cooperates with the signal transceiver end of the ranging module 130; or, the ranging module 130 is located outside the host outer cover 121.

[0086] Optionally, the scissors frame 141 is fixedly connected to the host outer cover 121.

[0087] See Figure 6 As shown, the embodiments of the present application provide a Figure 1 partial structural schematic diagram of the clothes dryer after removing the host component 110. As Figure 6 shown, an embodiment is shown in which the ranging module 130 is provided inside the host outer cover 121 and fixedly connected to the inner wall of the host outer cover 121. The inner wall of the host outer cover 121 is provided with an installation structure 1212 for installing the ranging module 130.

[0088] In some embodiments, the distance measurement module 130 is also disposed at at least one of the following positions at the bottom of the host component 110 for detecting the distance from the drying rod component 140.

[0089] The end and / or middle part in the length direction of the host component 110 is used for detecting the inclination state of the drying rod component 140 in the length direction. The two ends in the width direction of the host component 110 are used for detecting the inclination state of the drying rod component 140 in the width direction.

[0090] Optionally, the distance measurement module 130 is disposed at the end and / or middle part in the length direction of the host component 110. The inclination state of the drying rod component 140 in the length direction can be judged according to the measured distance. The distance measurement module 130 is disposed at both ends in the width direction of the host component 110. The distance measurement module 130 may include a signal transmitter disposed towards the mating part, and the mating part includes a signal receiver disposed towards the signal transmitter. By comparing whether the measured distances of the two distance measurement modules 130 are consistent, it is judged whether the drying rod component 140 is inclined in the width direction.

[0091] See Figure 7 As shown, an embodiment of the present application provides a Figure 1 Partial structural schematic diagram of the drying machine shown after removing the host component 110 and the distance measurement module 130. As Figure 7 As shown, two second through holes 1211 are formed in the host outer cover 121, that is, two second through holes 1211 are formed in the installation structure 1212 for installing the infrared distance measurement module 131. One second through hole 1211 is correspondingly arranged with the infrared transmitting unit 1311 for allowing the first signal to pass through; the other second through hole 1211 is correspondingly arranged with the infrared receiving unit 1312 for allowing the second signal to pass through.

[0092] In some embodiments, the drying rod component 140 includes two drying rods 142 arranged in parallel, brackets 143 respectively connecting the two drying rods 142, and end caps arranged at the ends of the drying rods 142; the distance measurement module 130 is also disposed at at least one of the following positions to detect the distance from the object below it:

[0093] The bottom of both ends of any one of the drying rods 142, or the bottom of each end cap, is used for detecting the inclination state of the drying rod component 140 in the length direction;

[0094] The bottoms of both ends along the length direction of the bracket 143, or the bottom of each drying rod 142, are used for detecting the inclination state of the drying rod component 140 in the width direction.

[0095] Specifically, the ranging module 130 is disposed at the bottom of both ends of any drying rod 142 or at the bottom of each end cap. By comparing the measured distances of the two ranging modules 130, it can be detected whether the drying rod assembly 140 is tilted in its length direction (for example, the height of any end of the drying rod 142 may be higher than the height of the other end). The ranging module 130 is disposed at the bottom of both ends along the length direction of the bracket 143 or at the bottom of each drying rod 142. By comparing the measured distances of the two ranging modules 130, it can be detected whether the drying rod assembly 140 is tilted in its width direction (for example, the height at which any drying rod 142 is located is different from the height at which the other drying rod 142 is located).

[0096] As an example, the ranging module 130 is arranged at the bottom of both ends of any drying rod 142 or at the bottom of each end cap. The ranging module 130 measures the distance between itself and the ground (i.e., the object located below it). When the difference between the measured distances of the two ranging modules 130 at the bottom of both ends of any drying rod 142 is within the range of the second predetermined threshold, the two measured distances are approximately equal, and the drying rod assembly 140 is in a horizontal state in its length direction and there is no tilt; when the difference between the measured distances of the two ranging modules 130 at the bottom of both ends of any drying rod 142 is not within the range of the second predetermined threshold (for example, the height of any end of the drying rod 142 may be higher than the height of the other end), the two measured distances deviate greatly, and the drying rod assembly 140 is tilted in its length direction. Similarly, the principle of the ranging module 130 arranged at the bottom of each end cap for detecting the tilt state of the drying rod assembly 140 in the length direction is the same.

[0097] As an example, the ranging module 130 is arranged at the bottom of both ends along the length direction of the bracket 143 or at the bottom of each drying rod 142. The ranging module 130 measures the distance between itself and the ground (i.e., the object located below it). When the difference between the measured distances of the two ranging modules 130 at the bottom of both ends along the length direction of the bracket 143 is within the range of the third predetermined threshold, the two measured distances are approximately equal, and the drying rod assembly 140 is in a horizontal state in its width direction and there is no tilt; when the difference between the measured distances of the two ranging modules 130 at the bottom of both ends along the length direction of the bracket 143 is not within the range of the third predetermined threshold (for example, the height at which any drying rod 142 is located is different from the height at which the other drying rod 142 is located), the two measured distances deviate greatly, and the drying rod assembly 140 is tilted in its length direction. Similarly, the principle of the ranging module 130 arranged at the bottom of each drying rod 142 for detecting the tilt state of the drying rod assembly 140 in the width direction is the same.

[0098] See Figure 8 As shown, an embodiment of the present application provides a Figure 1Schematic side view structure diagram of the clothes dryer shown. Two ranging modules 130 are at the bottoms of both ends of the bracket 143 in the length direction. The difference between the measured distances of the two ranging modules 130 is within the fourth predetermined threshold. At this time, the width direction of the clothes drying rod assembly 140 remains horizontal.

[0099] See Figure 9 As shown, an embodiment of the present application provides a Figure 1 Schematic side view structure diagram of the clothes dryer shown when it is in an inclined state. Combining Figure 9 and Figure 8 As shown, the clothes drying rod assembly 140 of the clothes dryer is in an inclined state in the width direction. Since the two ranging modules 130 are arranged at the bottoms of both ends of the bracket 143 in the length direction, by comparing the measured distances of the two ranging modules 130, that is, the distance between the ranging module 130 itself and the ground, the difference between the two measured distances is not within the fourth predetermined threshold and the deviation is large, it is determined that the clothes drying rod assembly 140 is inclined in the width direction.

[0100] Optionally, the principle of tilt detection of the ranging module 130 arranged at other positions of the clothes drying rod assembly 140 is the same.

[0101] See Figure 10 As shown, a schematic framework diagram of the main control board 111 controlling the alarm device 150 to give an alarm according to the reflection information of the ranging module 130 is provided in an embodiment of the present application. As Figure 10 shown, the clothes dryer tilt detection system further includes: an alarm device 150. The alarm device 150 is connected to the main control board 111. The alarm device 150 is configured to receive an alarm instruction sent by the main control board 111 and give an alarm according to the alarm instruction. The alarm device 150 and the main control board 111 may be electrically connected or in a wired communication connection. In practical applications, the alarm device 150 and the main control board 111 may also adopt a wireless communication connection.

[0102] Optionally, the main control board 111 is configured to send an alarm instruction to the alarm device 150 when it is determined that the clothes dryer is in an inclined state. The way of giving an alarm may be a voice prompt, a beeping sound may be played, or prompt text may be displayed, etc.

[0103] The main control board 111 can 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 various exemplary logic blocks, modules, and circuits described in connection with the disclosure of the present application. The main control board 111 can also be a combination that implements computing functions, such as a combination including one or more microprocessors, a combination of a DSP and a microprocessor, etc.

[0104] In the drying machine according to the embodiment of the present application, when it is used abnormally and there is serious unilateral hanging weight, the first through hole 144 on the drying rod outer cover 141 of the drying rod assembly 140 is offset, and the infrared signal fails to reach the ground, determining abnormal use. The alarm device 150 gives an alarm reminder, facilitating the user to process it in time and ensuring the normal use of the drying machine. Moreover, in the embodiment of the present application, the tilt detection and wave control functions are realized through the measurement distance detected by the ranging module 130. The ranging module 130 can detect unilateral hanging weight, and wave detection can be performed through the first signal, so that the lifting of the drying rod assembly 140 can be conveniently controlled.

[0105] It should be understood that although the flowchart of the embodiment of the present application indicates each operation step by an arrow, the execution order of these steps is not limited to the order indicated by the arrow. Unless there is a clear description in this application, in some implementation scenarios of the embodiment of the present application, the implementation steps in each flowchart can be executed in other orders according to requirements. In addition, some or all of the steps in each flowchart may include multiple sub-steps or multiple stages based on the actual implementation scenario. Some or all of these sub-steps or stages can be executed at the same time, and each sub-step or stage among these sub-steps or stages can also be executed at different times respectively. In the scenario where the execution times are different, the execution order of these sub-steps or stages can be flexibly configured according to requirements, and the embodiment of the present application does not limit this.

[0106] The above are only optional implementation manners of some implementation scenarios of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical concept of the solution of the present application, other similar implementation means based on the technical idea of the present application also belong to the protection scope of the embodiment of the present application.
