Description

Technical Field

[0001] This application relates to the technical field of clothes drying racks, and more specifically, to a control method, system, clothes drying rack, storage medium, and program product for 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 generally require manual voice control or remote control to control the raising, lowering, or stopping of the drying rod assembly, which is cumbersome to operate. Summary of the Invention

[0004] This application provides a control method, system, clothes dryer, storage medium, and program product for a clothes drying rack, which solves the technical problem of cumbersome control operation of the drying rod assembly in existing clothes drying racks.

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

[0006] Obtain a first distance measured by a distance measuring device; the distance measuring device is located at the bottom of the main body and / or drying rod assembly of the clothes dryer; the first distance includes the distance between the distance measuring device and an object located below the distance measuring device;

[0007] Based on the current state and first distance of the drying rack assembly, control the drying rack assembly to perform corresponding operations.

[0008] In one possible implementation, based on the current state of the drying rack assembly and a first distance, the drying rack assembly is controlled to perform corresponding operations, including at least one of the following:

[0009] Obtain the second distance related to the drying rack assembly; compare the first distance and the second distance; based on the comparison result and the current state of the drying rack assembly, control the drying rack assembly to perform the corresponding operation;

[0010] Obtain at least two first distances within a preset time period; based on the changing trends of the at least two first distances and the current state of the drying rack assembly, control the drying rack assembly to perform corresponding operations.

[0011] In one possible implementation, the second distance associated with the drying rod assembly includes at least one of the following:

[0012] The current height and distance the drying rack assembly has descended;

[0013] The distance between the drying rack assembly and the ground when it is at its upper limit position;

[0014] The distance between the current height of the drying rack assembly and the ground.

[0015] In one possible implementation, if the first distance is measured by a ranging device located at the bottom of the main unit, based on the current state of the drying rack assembly and the first distance, the drying rack assembly is controlled to perform corresponding operations, including controlling the drying rack assembly to rise in at least one of the following situations:

[0016] The drying rack assembly is at the lower limit position, and the difference between the first distance and the current descent height of the drying rack assembly is not within the preset first threshold range, or the first distance is less than the distance between the drying rack assembly and the ground when it is at the upper limit position;

[0017] The drying rack assembly stops at a position that is neither the upper nor lower limit, and the first distance is less than the current descent height of the drying rack assembly;

[0018] The drying rack assembly is in a descending state, and the duration during which the first distance is less than the distance between the drying rack assembly and the ground when it is in the upper limit position is greater than a preset first duration.

[0019] In one possible implementation, when the drying rack assembly is in the descending state, if the duration of the first distance being less than the distance between the drying rack assembly and the ground when it is at its upper limit position is greater than a preset second duration, then the drying rack assembly is controlled to stop descending.

[0020] If the drying rack assembly stops descending for a preset third duration, and the first distance is still less than the distance between the drying rack assembly and the ground when it is at its upper limit position, or the first distance is less than the current descending height of the drying rack assembly, then control the drying rack assembly to rise.

[0021] If the drying rack assembly stops descending for a preset third duration, and the difference between the first distance and the distance between the drying rack assembly and the ground when it is at its upper limit position is within a preset second threshold range, then the drying rack assembly will be controlled to continue descending.

[0022] In one possible implementation, if the first distance is measured by a ranging device located at the bottom of the main unit, based on the current state of the drying rack assembly and the first distance, the drying rack assembly is controlled to perform corresponding operations, including controlling the drying rack assembly to descend in at least one of the following cases:

[0023] The drying rack assembly stops at a position that is neither the upper limit nor the lower limit, and the first distance is less than the distance between the drying rack assembly and the ground when it is at the upper limit position, and greater than the current descent height of the drying rack assembly;

[0024] The drying rack assembly is at its upper limit position, and the first distance is less than the distance between the drying rack assembly and the ground when it is at its upper limit position;

[0025] The drying rack assembly is in an upward state, and the duration for which the first distance is less than the distance between the drying rack assembly and the ground when it is in the upper limit position is greater than the preset fourth duration.

[0026] In one possible implementation, when the drying rack assembly is in the rising state, if the duration of the first distance being less than the distance between the drying rack assembly and the ground when it is at its upper limit position is greater than a preset fifth duration, then the drying rack assembly is controlled to stop rising.

[0027] If the drying rack assembly stops rising for a preset sixth time period, and the first distance is still less than the distance between the drying rack assembly and the ground when it is at its upper limit position, then control the drying rack assembly to descend.

[0028] If the drying rack assembly stops rising for a preset seventh time period, and the difference between the first distance and the distance between the drying rack assembly and the ground when it is at its upper limit position is within a preset second threshold range, then the drying rack assembly will be controlled to continue rising.

[0029] In one possible implementation, if the first distance is measured by a distance measuring device located at the bottom of the drying rack assembly, based on the current state of the drying rack assembly and the first distance, the drying rack assembly is controlled to perform corresponding operations, including at least one of the following:

[0030] If the drying rack assembly is at its upper limit position and the first distance is less than the distance between the current height of the drying rack assembly and the ground, then control the drying rack assembly to descend.

[0031] If the drying rack assembly is at the lower limit position and the first distance is less than the distance between the current height position of the drying rack assembly and the ground, then control the drying rack assembly to rise.

[0032] In one possible implementation, based on at least two trends in the change of the first distance and the current state of the drying rack assembly, the drying rack assembly is controlled to perform corresponding operations, including at least one of the following:

[0033] If at least two first distances gradually decrease and the drying rack assembly is in a non-upper limit position, then control the drying rack assembly to rise;

[0034] If at least two first distances gradually increase and the drying rod assembly is in a position other than the lower limit, then control the drying rod assembly to descend.

[0035] In one possible implementation, when the ranging device is located at the bottom of the main unit, the drying rod assembly has a through hole that cooperates with the ranging device. When the drying rod assembly is in a horizontal state, the first signal emitted by the ranging device passes through the through hole; when the drying rod assembly is in an inclined state, the first signal emitted by the ranging device is reflected by the drying rod assembly.

[0036] Based on the current state of the drying rack assembly and the first distance, control the drying rack assembly to perform corresponding operations, including:

[0037] If the difference between the first distance and the current descent height of the drying rack assembly is not within the preset first threshold range, it is determined that the drying rack assembly is tilted.

[0038] Based on the current state of the drying rack assembly, control the drying rack assembly to perform operations related to anti-tilt.

[0039] Secondly, embodiments of this application provide a control system for a clothes drying rack, including a main controller and a ranging device;

[0040] A distance measuring device is installed at the bottom of the main unit and / or drying rod assembly of a clothes drying rack to detect the distance between the distance measuring device itself and an object located below the distance measuring device.

[0041] The main controller is connected to the ranging device to execute the steps of the method in the first aspect.

[0042] Thirdly, embodiments of this application provide a clothes drying rack, including: the control system of the clothes drying rack of the second aspect.

[0043] Fourthly, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the method of the first aspect.

[0044] Fifthly, embodiments of this application provide a computer program product, including a computer program that, when executed by a processor, implements the steps of the method of the first aspect.

[0045] The beneficial effects of the technical solutions provided in this application are:

[0046] This embodiment of the application can measure a first distance using a ranging device. Since the first distance includes the distance between the ranging device and the object located below it, corresponding control operations can be performed based on the current state of the clothes drying rack assembly and various situations involving the first distance. For example, the first distance will change depending on whether the first signal emitted by the ranging device encounters an obstacle, the clothes drying rack assembly encounters an obstacle, or the user waves their hand below the ranging device. Combined with the current state of the clothes drying rack assembly, the assembly can be controlled to rise, fall, or stop. Therefore, this embodiment of the application can achieve automatic control of the clothes drying rack in different application scenarios, reducing manual operation and simplifying the control process.

[0063] See Figure 1 As shown, this application provides a schematic diagram of a clothes drying rack. The clothes drying rack provided in this application is an application product of the control method for the clothes drying rack described in this application. This application also provides a control system for the clothes drying rack, including a main controller and a ranging device. See also...

The main controller is connected to the distance measuring device and is used to execute the steps of the control method of the clothes drying rack according to the embodiments of this application.

[0064] This application also provides a clothes drying rack, including: a control system for the clothes drying rack according to this application embodiment. See also... Figure 1 As shown, the clothes drying rack includes: a main unit assembly 110, a telescopic bracket assembly 120, and a drying rod assembly 130. The main unit assembly 110 includes a main controller, and a ranging device is installed at the bottom of the main unit assembly 110 and / or the drying rod assembly 130. 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 130. The telescopic bracket assembly 120 is a telescopic structure, and the drying rod assembly 130 moves up and down by the contraction and extension of the telescopic bracket assembly 120.

[0065] See Figure 2The flowchart shown is a control method for a clothes drying rack provided in this application embodiment. Specifically, the control method for the clothes drying rack includes: S201 to S202.

[0066] S201. Obtain a first distance measured by a distance measuring device; the distance measuring device is located at the bottom of the main unit 110 and / or the drying rod assembly 130 of the clothes drying machine; the first distance includes the distance between the distance measuring device and an object located below the distance measuring device.

[0067] Optionally, the ranging device is used to transmit a first signal and / or receive a second signal, generate ranging information based on the second signal, and send the ranging information to the main controller, so that the main controller determines a first distance based on the ranging information. Both the first and second signals can be infrared. The ranging device may include a signal transceiver for transmitting the first signal and receiving the second signal; or, the ranging device may include a signal transmitter for transmitting the first signal, and a corresponding mating component in the vertical direction as a signal receiver for receiving the second signal; or, the ranging device may include a signal receiver for receiving the second signal, and a corresponding mating component in the vertical direction as a signal transmitter for transmitting the first signal.

[0068] Optionally, the ranging device may include an infrared emitting unit and an infrared receiving unit, emitting a first signal and receiving a second signal. The ranging principle of the embodiments of this application can refer to the principle of infrared ranging. The infrared emitting unit may be an infrared signal emitting diode, and the infrared receiving unit may be an infrared signal receiving diode. The emitting diode emits an infrared signal of a specific frequency, and the receiving diode receives the infrared signal of this frequency. When the detection direction of the infrared signal encounters an obstacle, the infrared signal is reflected back and received by the receiving diode, and ranging information is generated based on the second signal.

[0069] The main controller can control the power supply signal to power the infrared emitting unit, that is, output a constant predetermined voltage to the infrared emitting unit. The main controller can control the timing of infrared emission by the infrared emitting unit based on the emission information.

[0070] Optionally, the main controller can control the infrared emitting unit to emit a first signal based on the emission information, and determine a first distance based on the ranging 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 can also determine the first distance based on the ranging information, the time of receiving the emission information, and the propagation speed of the first signal.

[0071] S202. Based on the current state of the drying rod assembly 130 and the first distance, control the drying rod assembly 130 to perform corresponding operations.

[0072] In some embodiments, based on the current state of the drying rod assembly 130 and a first distance, the drying rod assembly 130 is controlled to perform corresponding operations, including at least one of steps A1 to A2.

[0073] Step A1: Obtain the second distance related to the drying rod assembly 130; compare the first distance and the second distance; based on the comparison result and the current state of the drying rod assembly 130, control the drying rod assembly 130 to perform the corresponding operation.

[0074] Optionally, the current state of the drying rod assembly 130 can be that the drying rod assembly 130 is in the upper limit position, the drying rod assembly 130 is in the lower limit position, the drying rod assembly 130 is stopped at neither the upper limit position nor the lower limit position, the drying rod assembly 130 is in a descending state, the drying rod assembly 130 is in an ascending state, etc.

[0075] Optionally, the upper limit position is the highest position that the clothes drying assembly 130 of the clothes drying machine can reach, and the lower limit position is the lowest position that the clothes drying assembly 130 of the clothes drying machine can reach.

[0076] In some embodiments, the second distance associated with the drying rod assembly 130 includes at least one of the following: the current height distance of the drying rod assembly 130 as it descends; the distance between the drying rod assembly 130 and the ground when it is in its upper limit position; and the distance between the drying rod assembly 130 and the ground at its current height position.

[0077] Optionally, the current height position of the drying rod assembly 130 refers to its current location, which can be any of the following: upper limit position, lower limit position, or a position between the upper and lower limits. The current descent distance of the drying rod assembly 130 can be the height distance directly obtained by controlling the movement of the drying rod assembly 130 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, and the height distance can also be determined based on the Hall signal output by the Hall sensor, thereby enabling real-time detection of the height distance of the moving drying rod assembly 130.

[0078] Optionally, the main controller can also calculate the height distance by multiplying the average motor speed by the running time.

[0079] This application embodiment can compare a first distance and a second distance, and based on the comparison result and the current state of the drying rod assembly 130, control the drying rod assembly 130 to perform corresponding operations, thereby realizing automatic control of the clothes drying machine in different application scenarios, reducing manual operation, and making the control process simpler.

[0080] Step A2: Obtain at least two first distances within a preset time period; based on the changing trends of the at least two first distances and the current state of the drying rod assembly 130, control the drying rod assembly 130 to perform corresponding operations.

[0081] Optionally, the trend of change of at least two first distances can be either gradually increasing or gradually decreasing.

[0082] This application embodiment can also control the drying rod assembly 130 to perform corresponding operations based on the changing trend of the first distance and the current state of the drying rod assembly 130, which is suitable for application scenarios where users control the raising or lowering of the drying rod assembly 130 by hand.

[0083] Based on the above steps S201 to S202, the embodiments of this application can obtain a first distance by measuring the distance using a ranging device. Since the first distance includes the distance between the ranging device and the object located below the ranging device, corresponding control operations can be performed according to the current state of the clothes drying rack assembly 130 and various situations involving the first distance. For example, the first distance will change under different circumstances, such as when the first signal emitted by the ranging device encounters an obstacle, when the clothes drying rack assembly 130 encounters an obstacle, or when the user waves their hand below the ranging device. Simultaneously, combined with the current state of the clothes drying rack assembly 130, the assembly can be controlled to rise, fall, or stop. Therefore, the embodiments of this application can achieve automatic control of the clothes drying rack in different application scenarios, reducing manual operation and simplifying the control process.

[0084] In some embodiments, when the first distance is measured by a ranging device disposed at the bottom of the main unit assembly 110, the drying rod assembly 130 is controlled to perform corresponding operations based on the current state of the drying rod assembly 130 and the first distance, including controlling the drying rod assembly 130 to rise in at least one of cases B1 to B3.

[0085] Situation B1: The drying rod assembly 130 is at the lower limit position, and the difference between the first distance and the current descent height of the drying rod assembly 130 is not within the preset first threshold range, or the first distance is less than the distance between the drying rod assembly 130 and the ground when it is at the upper limit position.

[0086] See Figure 3 As shown, this application embodiment provides a structural schematic diagram of the current state of the first type of drying rod assembly 130. (As...) Figure 3 As shown, the drying rod assembly 130 is at the lower limit position, the current descent height of the drying rod assembly 130 is H1, and the distance between the drying rod assembly 130 and the ground when it is at the upper limit position is H2.

[0087] Since the ranging device is installed at the bottom of the main unit 110, the first distance H should normally be the distance H1 of the current descent height of the drying rod assembly 130 or the distance H2 between the drying rod assembly 130 and the ground when it is at its upper limit position. That is, the difference between the first distance H and the current descent height H1 of the drying rod assembly 130 is a predictable calculated value that is within the preset first threshold range. When it is not within the preset first threshold range, for example, H is not equal to H1, it may be because the drying rod assembly 130 is tilted or the user blocks the first signal of the ranging device with their hand, causing the first distance H to change. At this time, the drying rod assembly 130 can be controlled to rise.

[0088] Optionally, when the drying rod assembly 130 is in the lower limit position, the first distance H should normally be the distance between the drying rod assembly 130 and the ground when it is in the upper limit position. When the first distance H is less than the distance between the drying rod assembly 130 and the ground when it is in the upper limit position, the drying rod assembly 130 can be controlled to rise.

[0089] In case B2, the drying rod assembly 130 stops at a position that is neither the upper limit nor the lower limit, and the first distance is less than the current descent height of the drying rod assembly 130.

[0090] See Figure 4 As shown, this application embodiment provides a structural schematic diagram of the current state of the second type of drying rod assembly 130. (As...) Figure 4 As shown, the drying rod assembly 130 stops at neither the upper limit position nor the lower limit position. The current descent height of the drying rod assembly 130 is H1, and the distance between the drying rod assembly 130 and the ground when it is at the upper limit position is H2.

[0091] Since the ranging device is installed at the bottom of the main unit 110, the first distance H is normally the distance between the ranging device and the drying rod assembly 130, that is, the current descending height distance of the drying rod assembly 130 is H1. When the first distance H is less than the current descending height distance of the drying rod assembly 130, it can be applied to the situation where there is a user's hand controlling the ranging device and the drying rod assembly 130, and the drying rod assembly 130 can be controlled to rise.

[0092] As an example, when the object below the ranging device is the user's hand, and the user controls the drying rod assembly 130 by reaching out, the user's hand is located between the main unit assembly 110 and the drying rod assembly 130. The initial distance will be less than the current descent height of the drying rod assembly 130. This can be applied to the drying rod assembly 130 continuing to perform an ascent operation after the user controls the drying rod assembly 130 to stop at a certain height during the descent process.

[0093] Situation B3: The drying rod assembly 130 is in a descending state, and the duration of the first distance being less than the distance between the drying rod assembly 130 and the ground when it is in the upper limit position is greater than the preset first duration.

[0094] See Figure 5 As shown, this application embodiment provides a structural schematic diagram of the current state of the third type of drying rod assembly 130. (As...) Figure 5 As shown, the drying rack assembly 130 is in a descending state (as indicated by the arrow), the current descending height of the drying rack assembly 130 is H1, and the distance between the drying rack assembly 130 and the ground when it is at its upper limit position is H2.

[0095] Since the distance measuring device is installed at the bottom of the main unit 110, the first distance H should normally be the distance between the drying rod assembly 130 and the ground when it is in the upper limit position, which is H2. When the duration of the first distance being less than the duration of the distance between the drying rod assembly 130 and the ground when it is in the upper limit position is greater than the preset first duration, the user's hand can be positioned between the distance measuring device and the ground, and the drying rod assembly 130 can be controlled to rise.

[0096] As an example, when the drying rack assembly 130 is in a descending state, and the duration of the first distance being less than the distance between the drying rack assembly 130 and the ground when it is at its upper limit position is greater than a preset first duration, the drying rack assembly 130 can be controlled to rise. In this way, when the drying rack assembly 130 is triggered to rise during the descending process, it does not necessarily need to stop.

[0097] In some embodiments, when the drying rod assembly 130 is in a descending state, if the duration of the first distance being less than the distance between the drying rod assembly 130 and the ground when it is in the upper limit position is greater than a preset second duration, then the drying rod assembly 130 is controlled to stop descending.

[0098] Optionally, if the first distance H is less than the distance H2 between the drying rod assembly 130 and the ground when it is at the upper limit position and the time is greater than the preset second time, the user's hand can be continuously placed between the distance measuring device and the ground to control the drying rod assembly 130 to stop descending.

[0099] In some embodiments, when the drying rod assembly 130 is in a descending state, if the drying rod assembly 130 stops descending for a preset third duration, and the first distance is still less than the distance between the drying rod assembly 130 and the ground when it is in the upper limit position, or the first distance is less than the current descending height of the drying rod assembly 130, then the drying rod assembly 130 is controlled to rise.

[0100] Specifically, the drying rod assembly 130 stops descending for a preset third duration, and the first distance H is less than the current descending height distance H1 of the drying rod assembly 130, which also satisfies the control operation of controlling the drying rod assembly 130 to rise. This control method takes into account that in actual operation, the user may only keep his hand in a certain position for gesture control, but it is not ruled out that after controlling the drying rod assembly 130 to stop descending, the user may place his hand between the main unit assembly 110 and the drying rod assembly 130, thereby triggering the operation of the drying rod assembly 130 to rise.

[0101] In some embodiments, when the drying rod assembly 130 is in a descending state, if the drying rod assembly 130 stops descending for a preset third duration, and the difference between the first distance and the distance between the drying rod assembly 130 and the ground when it is in the upper limit position is within a preset second threshold range, then the drying rod assembly 130 is controlled to continue descending.

[0102] Specifically, when the drying rod assembly 130 stops descending for a preset third duration, and the difference between the first distance and the distance between the drying rod assembly 130 and the ground when it is at its upper limit position is within a preset second threshold range, controlling the drying rod assembly 130 to continue descending is to avoid accidentally triggering an ascent.

[0103] In some embodiments, when the first distance is measured by a ranging device disposed at the bottom of the main unit assembly 110, the drying rod assembly 130 is controlled to perform a corresponding operation based on the current state of the drying rod assembly 130 and the first distance, including controlling the drying rod assembly 130 to descend in at least one of cases C1 to C3.

[0104] In case C1, the drying rod assembly 130 stops at a position that is neither the upper limit nor the lower limit, and the first distance is less than the distance between the drying rod assembly 130 and the ground when it is at the upper limit position, and greater than the current descent height of the drying rod assembly 130.

[0105] See Figure 4 As shown, the drying rod assembly 130 stops at neither the upper nor lower limit position. The user places their hand between the drying rod assembly 130 and the ground, making the first distance H less than the distance H2 between the drying rod assembly 130 and the ground when it is at the upper limit position, but greater than the current descent height H1 of the drying rod assembly 130. This allows the user to continue controlling the descent of the drying rod assembly 130. This method is applicable to situations where the user controls the drying rod assembly 130 to stop at a certain height during the descent process, and the drying rod assembly 130 can continue to perform descent operations afterward.

[0106] Case C2: The drying rod assembly 130 is in the upper limit position, and the first distance is less than the distance between the drying rod assembly 130 and the ground when it is in the upper limit position.

[0107] See Figure 6As shown, this application embodiment provides a structural schematic diagram of the current state of the fourth type of drying rod assembly 130. (As...) Figure 6 As shown, the drying rod assembly 130 is in the upper limit position, and the distance between the drying rod assembly 130 and the ground when it is in the upper limit position is H2.

[0108] Optionally, when the drying rod assembly 130 is in the upper limit position, the user places his hand between the drying rod assembly 130 and the ground. The first distance H is less than the distance H2 between the drying rod assembly 130 and the ground when it is in the upper limit position, which can control the drying rod assembly 130 to descend.

[0109] In case C3, the drying rod assembly 130 is in an upward state, and the duration of the first distance being less than the distance between the drying rod assembly 130 and the ground when it is in the upper limit position is greater than the preset fourth duration.

[0110] See Figure 7 As shown, this application embodiment provides a structural schematic diagram of the current state of the fifth type of drying rod assembly 130. (As...) Figure 7 As shown, the drying rod assembly 130 is in an upward state (as indicated by the arrow), the current downward height of the drying rod assembly 130 is H1, and the distance between the drying rod assembly 130 and the ground when it is at its upper limit position is H2.

[0111] Optionally, when the drying rod assembly 130 is in the raised state, the user places his hand between the distance measuring device and the ground. If the duration of the first distance H being less than the distance H2 between the drying rod assembly 130 and the ground when it is in the upper limit position is greater than the preset fourth duration, the user can control the drying rod assembly 130 to descend.

[0112] In some embodiments, when the drying rod assembly 130 is in the rising state, if the duration of the first distance being less than the distance between the drying rod assembly 130 and the ground when it is in the upper limit position is greater than a preset fifth duration, the drying rod assembly 130 is controlled to stop rising.

[0113] Optionally, when the drying rod assembly 130 is in the rising state, if the user places his hand between the distance measuring device and the ground, and the duration of the first distance H being less than the distance H2 between the drying rod assembly 130 and the ground when it is in the upper limit position is greater than the preset fifth duration, the user can control the drying rod assembly 130 to stop rising.

[0114] For example, the fifth duration can be shorter than the fourth duration. When the user briefly places their hand between the distance measuring device and the ground, the drying rack assembly 130 can be controlled to stop rising; when the user places their hand between the distance measuring device and the ground for a longer period of time, the drying rack assembly 130 can be controlled to descend.

[0115] In some embodiments, when the drying rod assembly 130 is in the rising state, if the drying rod assembly 130 stops rising for a preset sixth time period, and the first distance is still less than the distance between the drying rod assembly 130 and the ground when it is in the upper limit position, then the drying rod assembly 130 is controlled to descend.

[0116] Optionally, when the drying rack assembly 130 is in the rising state, and the user places their hand between the distance measuring device and the ground, if the first distance H is less than the distance H2 between the drying rack assembly 130 and the ground when it is in the upper limit position for a duration greater than a preset fifth duration, the user can control the drying rack assembly 130 to stop rising. If the rising is stopped for a preset sixth duration, and the user continues to place their hand between the distance measuring device and the ground, and the first distance is still less than the distance between the drying rack assembly 130 and the ground when it is in the upper limit position, the user can control the drying rack assembly 130 to descend. For example, if the user accidentally triggers the rising, after controlling the drying rack assembly 130 to stop rising, the user can control the drying rack assembly 130 to descend.

[0117] In some embodiments, when the drying rod assembly 130 is in the rising state, if the drying rod assembly 130 stops rising for a preset seventh time period, and the difference between the first distance and the distance between the drying rod assembly 130 and the ground when it is in the upper limit position is within a preset second threshold range, then the drying rod assembly 130 is controlled to continue rising.

[0118] Optionally, when the drying rack assembly 130 is in the rising state, and the user places their hand between the distance measuring device and the ground, if the duration for which the first distance H is less than the distance H2 between the drying rack assembly 130 and the ground when it is at its upper limit position exceeds a preset fifth duration, the drying rack assembly 130 is controlled to stop rising. If the duration for which the drying rack assembly 130 stops rising is a preset seventh duration, and the difference between the first distance and the distance between the drying rack assembly 130 and the ground when it is at its upper limit position is within a preset second threshold range, the drying rack assembly 130 is controlled to continue rising to avoid accidental triggering. For example, if the user accidentally triggers the stop during the rising process of the drying rack assembly 130, after a period of time, if the difference between the first distance and the distance between the drying rack assembly 130 and the ground when it is at its upper limit position is within the preset second threshold range and the difference is very small, the drying rack assembly 130 can be controlled to continue rising.

[0119] In some embodiments, when the first distance is measured by a distance measuring device disposed at the bottom of the drying rod assembly 130, the drying rod assembly 130 is controlled to perform corresponding operations based on the current state of the drying rod assembly 130 and the first distance, including at least one of steps D1 to D2.

[0120] Step D1: If the drying rod assembly 130 is at its upper limit position and the first distance is less than the distance between the current height position of the drying rod assembly 130 and the ground, then control the drying rod assembly 130 to descend.

[0121] When the first distance H is measured by a distance measuring device installed at the bottom of the drying rod assembly 130, the first distance H is the distance between the drying rod assembly 130 and the ground. See also Figure 6 As shown, the drying rod assembly 130 is in the upper limit position, and the first distance H is the distance H2 between the drying rod assembly 130 and the ground when it is in the upper limit position.

[0122] Optionally, when the drying rod assembly 130 is in its upper limit position, the user places their hand between the distance measuring device and the ground, which will make the first distance H less than the distance H2 between the current height position of the drying rod assembly 130 and the ground, thus controlling the drying rod assembly 130 to descend.

[0123] Step D2: If the drying rod assembly 130 is at the lower limit position and the first distance is less than the distance between the current height position of the drying rod assembly 130 and the ground, then control the drying rod assembly 130 to rise.

[0124] Optionally, when the drying rod assembly 130 is in the lower limit position, the user places his hand between the distance measuring device and the ground, which will make the first distance H less than the distance H2 between the current height position of the drying rod assembly 130 and the ground, thus controlling the drying rod assembly 130 to rise.

[0125] In this embodiment of the application, when the first distance H is measured by a distance measuring device installed at the bottom of the drying rod assembly 130, the first distance is less than the distance between the current height position of the drying rod assembly 130 and the ground. The user can place their hand between the distance measuring device and the ground to control the movement of the drying rod assembly 130. If the drying rod assembly 130 is at the upper limit position, the drying rod assembly 130 is controlled to descend; if the drying rod assembly 130 is at the lower limit position, the drying rod assembly 130 is controlled to rise.

[0126] In some embodiments, based on the changing trends of at least two first distances and the current state of the drying rod assembly 130, the drying rod assembly 130 is controlled to perform corresponding operations, including at least one of steps E1 to E2.

[0127] Step E1: If at least two first distances gradually decrease and the drying rod assembly 130 is in a non-upper limit position, then control the drying rod assembly 130 to rise.

[0128] Step E2: If at least two first distances gradually increase and the drying rod assembly 130 is in a non-lower limit position, then control the drying rod assembly 130 to descend.

[0129] Specifically, the user raises their hand or makes a downward gesture, causing at least two first distances to gradually decrease or increase, thereby triggering the raising and lowering of the drying rack assembly 130. Therefore, in this embodiment of the application, if the first distance continuously decreases (e.g., a hand-raising gesture is made), it is determined to be an upward movement; conversely, if it increases, it is determined to be a downward movement.

[0130] In some embodiments, when the ranging device is located at the bottom of the main unit assembly 110, the drying rod assembly 130 has a through hole that cooperates with the ranging device. When the drying rod assembly 130 is in a horizontal state, the first signal emitted by the ranging device passes through the through hole; when the drying rod assembly 130 is in an inclined state, the first signal emitted by the ranging device is reflected by the drying rod assembly 130.

[0131] Based on the current state of the drying rod assembly 130 and the first distance, control the drying rod assembly 130 to perform corresponding operations, including:

[0132] If the difference between the first distance and the current descent height of the drying rod assembly 130 is not within the preset first threshold range, it is determined that the drying rod assembly 130 has tilted.

[0133] Based on the current state of the drying rack assembly 130, the drying rack assembly 130 is controlled to perform operations related to anti-tilt.

[0134] Optionally, if the difference between the first distance H and the current descent distance H1 of the drying rod assembly 130 is not within the preset first threshold range, then H is not equal to H1 and H is definitely less than H2, and it can be determined that the drying rod assembly 130 is tilted.

[0135] Since the drying rod assembly 130 of this application embodiment has a through hole, when the drying rod assembly 130 is in a horizontal state, the first signal emitted by the ranging device passes through the through hole. When the drying rod assembly 130 is in a tilted state, the first signal emitted by the ranging device is reflected by the drying rod assembly 130. Thus, it can be determined whether the drying rod assembly 130 is tilted based on the first distance, and a tilt alarm can be triggered.

[0136] An alarm device can be installed on the clothes drying rack assembly 130 or the main unit assembly 110. The alarm device is configured to receive alarm commands from the main controller and trigger an alarm accordingly. The main controller is configured to send an alarm command to the alarm device when it determines that the clothes drying rack is tilted. The alarm can be triggered by voice prompts, a buzzer sound, or displayed text.

[0137] As an example, in this embodiment of the application, when the drying rod assembly 130 is in the hanging position where the user actively lowers it to stop or triggers the lower limit to stop, the motor stops (the main controller detects the stop signal). The signal from the distance measuring device can smoothly pass through the through hole of the drying rod assembly 130 to the ground and then be reflected back. Assuming that the descent distance of the drying rod assembly 130 is the height distance H1 (the main controller can calculate it by multiplying the average motor speed by the running time; if it descends directly to the lower limit, H1 is the maximum travel by default), when the distance measuring device measures the first distance H≈H1, it determines that a tilt alarm is triggered.

[0138] In some embodiments, when the distance H measured by the ranging device is greater than or less than H1 and the measurement signal lasts for a certain period of time, it is determined that the drying rack assembly 130 is triggered to rise.

[0139] When a user waves their hand, the distance between the measuring device and the hand is measured. This waving motion can occur either above or below the drying rack assembly 130, but normally it occurs below. The set duration is to prevent accidental activation. This operation should also be triggered if the drying rack assembly 130 encounters an obstacle elsewhere, or even before any obstacle is touched. Although the drying rack assembly 130 may tilt upon encountering an obstacle, even a slight impact can trigger the corresponding operation.

[0140] As an example, when the drying rack assembly 130 is at the upper limit position (the main controller detects the upper limit signal), the signal from the distance measuring device can pass smoothly through the through hole of the drying rack assembly 130 until it is reflected back to the ground. When the distance measuring device measures a first distance H < H2 and the measurement signal is satisfied for a certain period of time, it is determined that the drying rack assembly 130 is triggered to descend.

[0141] As an example, when the drying rack assembly 130 is in the process of rising / falling, the main controller detects the rising / falling signal of the motor. When the distance measured is H≠H2 and the measurement signal is satisfied for a certain period of time, it determines that the drying rack assembly 130 is triggered to stop. After stopping, if the first distance H≠H2 is measured again, the reverse action is achieved.

[0142] As an example, if multiple distance measurements are taken at short intervals and the first distance H≠H2, a specific action is triggered, such as an alarm. The alarm can be indicated by switching lights on or off.

[0143] Existing clothes drying racks mainly control the raising and lowering of the drying rod assembly 130 via remote control, voice commands, or gentle lifting, which is complex and laborious to operate. The control method of the clothes drying rack in this embodiment can control the raising or lowering of the drying rod assembly 130 by waving a hand to block the first signal, thereby achieving a suitable position for drying or collecting clothes, which is labor-saving and convenient.
