Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and more specifically, to a control method for a clothes drying rack and a clothes drying rack. Background Technology

[0002] Clothes are an essential part of daily life. After wearing them, people wash and dry them. With the improvement of living standards, clothes drying racks have gradually replaced traditional clothes racks and clotheslines as a common household drying tool, greatly facilitating people's lives. A clothes drying rack generally consists of a main unit and a drying rod. To increase the drying area, some clothes drying racks are also equipped with a telescopic rod. The main unit is installed on the ceiling, and the drying rod is located below the main unit and can be raised and lowered. Clothes that need to be dried are hung on the drying rod.

[0003] Most existing clothes drying racks lack dynamic obstacle detection. Those with such functionality detect the tightness of the steel cable. During ascent, if an obstacle is encountered, the drying rod will come into contact with it, causing the motor current to rise due to the obstruction. Overcurrent protection typically stops the drying rack only when the motor current exceeds a preset value. However, in this situation, the drying rod is already under pressure from the obstacle, which can easily damage it and shorten the lifespan of both the rod and the drying rack.

[0004] As can be seen from the above, existing technologies have the problem that clothes drying racks cannot effectively avoid obstacles. Summary of the Invention

[0005] The main objective of this invention is to provide a control method and a clothes drying machine to solve the problem that clothes drying machines in the prior art cannot effectively avoid obstacles.

[0006] To achieve the above objectives, according to one aspect of the present invention, a control method for a clothes drying rack is provided, comprising: acquiring the current state of the drying rod of the clothes drying rack; if the current state of the drying rod is an obstructed state, controlling a first drive mechanism of the clothes drying rack to drive the drying rod to stop the currently executed first action and execute a second action, the second action being opposite in direction to the first action; acquiring the current state of the telescopic rod of the clothes drying rack; if the current state of the telescopic rod is an extended state, controlling a second drive mechanism of the clothes drying rack to drive the telescopic rod to retract.

[0007] Furthermore, the control method also includes: if the current state of the telescopic rod is the extended state, and it remains in the extended state after a first duration corresponding to the current time, controlling the second drive mechanism to drive the telescopic rod to retract.

[0008] Furthermore, the control method also includes: if the current state of the telescopic rod is the extended state, and it switches to the retracted state within a first duration corresponding to the current moment, controlling the first drive mechanism to drive the drying rod to perform the first action.

[0009] Furthermore, the control method also includes: if the current state of the telescopic rod is the retracted state, controlling the first drive mechanism to drive the drying rod to perform the first action to the first upper limit position.

[0010] Furthermore, the control method also includes issuing an alarm signal before controlling the second drive mechanism to retract the telescopic rod.

[0011] Furthermore, the control method also includes: after issuing an alarm signal, if the clothes drying machine receives an instruction to perform the first action, it controls the first drive mechanism to stop and continues to issue a second alarm signal.

[0012] Furthermore, the control method also includes: after issuing a second alarm signal and after a first duration, if the current state of the telescopic rod is still in the extended state, controlling the second drive mechanism to drive the telescopic rod to retract.

[0013] Furthermore, the control method also includes: controlling the second drive mechanism to retract the telescopic rod, and then controlling the first drive mechanism to perform the first action to the first upper limit position.

[0014] Furthermore, the control method also includes: after issuing a second alarm signal and after a first duration, if the current state of the telescopic rod switches to the retracted state, controlling the first drive mechanism to drive the drying rod to perform the first action, while continuing to acquire the current state of the drying rod and the current state of the telescopic rod.

[0015] Furthermore, the control method also includes: after issuing an alarm signal, if the clothes drying machine receives an instruction to perform a second action, controlling the first drive mechanism to drive the drying rod to perform the second action; after issuing an alarm signal, if the clothes drying machine receives other instructions besides the instructions to perform the first action and the instructions to perform the second action, executing the other instructions.

[0016] Furthermore, the control method also includes: determining a first determination condition in real time during the execution of the first action of the drying rod; if the first determination condition is met, determining that the current state of the drying rod is an obstruction state; wherein, the first determination condition includes the current change value of the first drive mechanism or the interval distance between the drying rod and the ceiling; if the current change value is greater than a first preset value, or the interval distance is less than a second preset value, determining that the current state of the drying rod is an obstruction state.

[0017] Furthermore, the control method also includes: acquiring the current value of the first drive mechanism; if the current state of the telescopic rod is the extended state and the current value is the first current, controlling the second drive mechanism to drive the telescopic rod to retract; if the current state of the telescopic rod is the extended state and the current value is the second current, controlling the second drive mechanism to drive the telescopic rod to retract; and controlling the first drive mechanism to drive the drying rod to perform a first action to the first upper limit position, wherein the second current is greater than the first current.

[0018] According to another aspect of the present invention, a clothes drying rack is provided, comprising a main unit, a drying rod, a telescopic rod, a first drive mechanism, a second drive mechanism, and a controller. The controller is electrically connected to both the first and second drive mechanisms. The drying rod is vertically and vertically connected to the main unit. The first drive mechanism drives the drying rod to perform a first action or a second action, wherein the second action is opposite in direction to the first action. The telescopic rod is retractably connected to the drying rod, and the second drive mechanism drives the telescopic rod to perform a retracting action. The controller acquires the current state of the drying rod and the telescopic rod. When the current state of the drying rod is an obstructed state and the current state of the telescopic rod is an extended state, the controller controls the first drive mechanism to stop the currently performing first action and perform the second action, and controls the second drive mechanism to retract the telescopic rod.

[0019] Furthermore, the clothes drying rack also includes: a current detection component, which is used to detect the current value and / or current change value of the first drive mechanism and send it to the controller, the controller is also used to determine whether the current state of the drying rod is an obstruction state based on at least one of the parameters of the current value and the current change value; and / or a first position detection component, which is used to detect the distance between the drying rod and the ceiling and send it to the controller, the controller is also used to determine whether the current state of the drying rod is an obstruction state based on the distance.

[0020] Furthermore, the clothes drying rack also includes a second position detection component, which is used to detect whether the current state of the telescopic rod is in the extended state and send the result to the controller.

[0021] Furthermore, the clothes drying rack also includes a filtering component, which is used to filter the current value and / or current change value of the first drive mechanism; the second position detection component includes a transmitter and a receiver, which is used to receive and process the detection signal emitted by the transmitter and send it to the controller, wherein one of the transmitter and the receiver is set on the drying rod, and the other is set at one of the positions on the telescopic rod, the ceiling, and the corresponding side wall of the drying rod.

[0022] Furthermore, the second position detection component is one of an infrared detection component, a laser detection component, or an ultrasonic detection component. When the second position detection component is an infrared detection component, the transmitter includes an infrared emitting element, and the receiver includes an infrared receiving element and a photoelectric conversion element. The photoelectric conversion element is used to convert the infrared signal emitted from the infrared emitting element and received by the infrared receiving element into an electrical signal and send it to the controller.

[0023] The control method for a clothes drying rack using the technical solution of this invention includes: acquiring the current state of the drying rod; if the current state of the drying rod is an obstruction state, controlling the first drive mechanism of the clothes drying rack to drive the drying rod to stop the currently executed first action and execute a second action, the second action being opposite in direction to the first action; acquiring the current state of the telescopic rod; if the current state of the telescopic rod is an extended state, controlling the second drive mechanism of the clothes drying rack to drive the telescopic rod to retract. By acquiring the current states of the drying rod and the telescopic rod, and controlling the actions of the first and second drive mechanisms accordingly, the clothes drying rack is driven to reverse its action when it is obstructed, and the telescopic rod is driven to retract when it is extended. This avoids situations where the drying rod encounters obstruction during the drying process, leading to current overload, or the telescopic rod expanding due to pressure against obstacles, thus damaging the clothes drying rack. This solves the problem in the prior art where clothes drying racks cannot effectively avoid obstacles. Attached Figure Description

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0038] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0039] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0040] To address the problem that existing clothes drying racks cannot effectively avoid obstacles, this invention provides a control method and a clothes drying rack. The clothes drying rack described below employs the control method described below.

[0041] like Figure 2As shown, the clothes drying rack includes a main unit 10, a drying rod 20, a telescopic rod 30, a first drive mechanism 40, a second drive mechanism 50, and a controller 70. The controller 70 is electrically connected to both the first drive mechanism 40 and the second drive mechanism 50. The drying rod 20 is vertically and vertically connected to the main unit 10. The first drive mechanism 40 drives the drying rod 20 to perform a first action or a second action, the second action being opposite in direction to the first action. The telescopic rod 30 is telescopically connected to the drying rod 20. The second drive mechanism 50 drives the telescopic rod 30 to perform a telescopic action. The controller 70 acquires the current state of the drying rod 20 and the telescopic rod 30. When the current state of the drying rod 20 is an obstructed state and the current state of the telescopic rod 30 is an extended state, the controller 70 controls the first drive mechanism 40 to stop the drying rod 20 from performing the first action and to perform the second action, and controls the second drive mechanism 50 to retract the telescopic rod 30.

[0042] In this embodiment, the controller 70 is an MCU control module.

[0043] In this embodiment, there are two drying rods 20, which are spaced apart and parallel to each other, and are respectively connected to the two sides of the main unit 10 in a height-adjustable manner. There are four telescopic rods 30, which are located at both ends of the two drying rods 20, thereby increasing the overall length of the drying rods 20 and thus increasing the number and efficiency of clothes that can be dried at one time.

[0044] In this embodiment, the clothes drying rack also includes a current detection component. The current detection component is used to detect the current value and / or current change value of the first drive mechanism 40 and send it to the controller 70. The controller 70 is also used to determine whether the current state of the drying rod 20 is an obstructed state based on at least one of the parameters, the current value and the current change value.

[0045] In this embodiment, the clothes drying rack also includes a first position detection component. The first position detection component is used to detect the distance between the drying rod 20 and the ceiling and send it to the controller 70. The controller 70 is also used to determine whether the current state of the drying rod 20 is an obstructed state based on the distance.

[0046] In this embodiment, the first drive mechanism 40 includes a first drive module and a lifting motor. The lifting motor is mounted on the main unit 10 and drivenly connected to the drying rod 20. The lifting motor is electrically connected to the controller 70 through the first drive module, thereby driving the drying rod 20 to move up and down under the control of the controller 70. The current detection component is used to detect the current value and current change value of the lifting motor. That is, in this embodiment, the first action is a rising action, and the second action is a falling action. Correspondingly, as... Figure 4 and Figure 9As shown, the second drive mechanism 50 includes a second drive module 51 and a telescopic motor 52. The telescopic motor 52 is mounted on the drying rod 20 and is drivenly connected to the telescopic rod 30. The telescopic motor 52 is electrically connected to the controller 70 through the second drive module 51, thereby driving the telescopic rod 30 to extend outward from the drying rod 20 and retract the drying rod 20 under the control of the controller 70.

[0047] like Figure 4 As shown, the clothes drying rack also includes a second position detection component 60. The second position detection component 60 detects whether the current state of the telescopic rod 30 is extended and sends this information to the controller 70. The second position detection component 60 is electrically connected to the controller 70, thereby transmitting the position signal of the telescopic rod 30 to the controller 70. The controller 70 determines the current state of the telescopic rod 30 based on the position signal detected by the second position detection component 60, and accordingly controls the second drive mechanism 50 to drive the telescopic rod 30 to extend outward from the drying rod 20 and retract the drying rod 20.

[0048] like Figure 5 As shown, the second position detection component 60 includes a transmitter 61 and a receiver 62. The receiver 62 receives and processes the detection signal emitted by the transmitter 61 and sends it to the controller 70. The transmitter 61 is mounted on the drying rod 20, and the receiver 62 is mounted on the telescopic rod 30. The second position detection component 60 also includes a power supply component 63, which is electrically connected to both the transmitter 61 and the receiver 62, thereby supplying power to both components.

[0049] Specifically, in this embodiment, the second position detection component 60 is an infrared detection component. For example... Figure 6 As shown, the transmitter 61 includes an infrared emitting element 611 and a transistor 612. The transistor 612 is used to control the switching on and off of the infrared emitting element 611. Specifically, the infrared emitting element 611 is connected to the collector of the transistor 612, the emitter of the transistor 612 is grounded, the base of the transistor 612 is connected to a resistor R1, and the emitter of the transistor 612 is also connected to the base of the transistor 612 through a resistor R2. Further, the infrared emitting element 611 is connected to the power supply terminal through a resistor R3. When the transmission control output is low, the transistor 612 is not turned on, and the infrared emitting element 611 will not emit an infrared signal; when the transmission control output is high, the transistor 612 is turned on, allowing the infrared emitting element 611 to emit infrared light. In this embodiment, the infrared emitting element 611 is an infrared emitting diode IR1.

[0050] like Figure 7As shown, receiver 62 includes an infrared receiving element 621 and a photoelectric conversion element. The photoelectric conversion element converts the infrared signal emitted from infrared emitting element 611 and received by infrared receiving element 621 into an electrical signal and sends it to controller 70, that is, sends the position signal of telescopic rod 30 to controller 70. Specifically, pin 2 of infrared receiving element 621 is grounded, and the 3.3V voltage is filtered by capacitors C1 and C2 and then applied to pin 3 of infrared receiving element 621. Pin 3 is also connected to resistor R6. Pin 1 of infrared receiving element 621 outputs a command signal, which is filtered by capacitor C3. Pin 1 is also connected to resistors R7 and R8. In this embodiment, infrared receiving element 621 is infrared receiving tube REC1, which receives the infrared signal emitted by emitting element 61 and converts it into an electrical signal. Specifically, infrared receiving tube REC1 receives infrared light on the photosensitive surface, then converts it into an electrical signal through photodiode in photoelectric conversion element, and after processing by amplifier and filter, finally outputs an infrared signal to controller 70.

[0051] like Figure 8 As shown, the power supply unit 63 includes an electronic switch 631 for controlling the on / off state of the second position detection component 60. Specifically, the two output terminals of the electronic switch 631 are connected to the transmitter 61 and the receiver 62 respectively, and the power supply terminal of the electronic switch 631 is also connected to the output terminal that supplies power to the transmitter 61 through a resistor R5. A resistor R4 is connected to the power supply terminal of the electronic switch 631.

[0052] In this embodiment, the second position detection component 60 can also be other types of detection modules such as a laser detection component or an ultrasonic detection component. Correspondingly, the transmitter 61 and the receiver 62 respectively include a laser emitting element and a laser receiving element, or an ultrasonic emitting element and an ultrasonic receiving element, which can be selected according to actual needs.

[0053] In an alternative embodiment, the receiver 62 may be placed in the external environment instead of on the telescopic rod 30. Specifically, the transmitter 61 is placed on the drying rod 20, and the receiver 62 is placed on the ceiling, or on the side wall corresponding to the drying rod 20. The location of the receiver 62 is not limited to the above locations; it is only necessary to detect the extension position of the telescopic rod 30, and can be selected according to actual needs.

[0054] In this embodiment, the clothes drying rack also includes a filtering component, which is used to filter the current value and current change value of the first drive mechanism 40. By performing multiple filtering processes on the current change value by the filtering component, the accuracy of the detection data is improved, and interference caused by erroneous operations, such as wind blowing the drying rod 20, can be eliminated as much as possible.

[0055] In this embodiment, the clothes drying rack also includes an alarm component for issuing an alarm signal. Specifically, the alarm component can be a light component, a buzzer component, or a voice component. Correspondingly, the alarm signal can be a flashing light, a buzzer sound, or a manually announced voice.

[0056] In this embodiment, the clothes drying rack also includes a remote control. The remote control is signal-connected to the controller 70 and is used to send action commands to the clothes drying rack. Specifically, the remote control has different buttons corresponding to raise, lower, extend, retract, and other commands. The clothes drying rack also includes a radio frequency (RF) receiver component. The remote control sends action commands to the controller 70 through the RF receiver component. The controller 70 parses the action commands and controls the corresponding components to perform the corresponding actions based on the action commands. For example, the user can press the raise button on the remote control to control the raising height of the drying rod 20 and the extendable rod 30.

[0057] In this embodiment, the clothes drying rack also includes a power supply component, which converts AC power into DC power to supply power to components such as the first drive mechanism 40, the second drive mechanism 50, the current detection component, the alarm component, the first position detection component, the second position detection component 60, and the controller 70. For example, it converts 220V AC voltage into 24V or 12V DC voltage. Furthermore, the power supply component also includes a DC-to-DC converter, used to convert high-voltage DC into low-voltage DC. For example, it converts 12V voltage into 5V voltage to power the controller 70, and converts 5V voltage into 3.3V voltage to power the second position detection component 60.

[0058] like Figure 1 As shown, the present invention also provides a control method for a clothes drying rack, comprising: acquiring the current state of the drying rod 20 of the clothes drying rack; if the current state of the drying rod 20 is an obstructed state, controlling the first drive mechanism 40 of the clothes drying rack to drive the drying rod 20 to stop the currently executed first action and execute a second action, the second action being opposite to the running direction of the first action; acquiring the current state of the telescopic rod 30 of the clothes drying rack; if the current state of the telescopic rod 30 is an extended state, controlling the second drive mechanism 50 of the clothes drying rack to drive the telescopic rod 30 to retract.

[0059] By adopting the above-mentioned control method for the clothes drying machine, the current state of the drying rod 20 and the telescopic rod 30 is obtained, and the actions of the first drive mechanism 40 and the second drive mechanism 50 are controlled accordingly. When the drying rod 20 is in an obstructed state, the drying rod 20 is driven to reverse its movement, and when the telescopic rod 30 is in an extended state, the telescopic rod 30 is driven to retract. This avoids situations where the drying rod 20 encounters obstruction during the clothes drying process, leading to current overload, or where the telescopic rod 30 is squeezed and expanded by obstacles, thereby damaging the clothes drying machine. This allows the clothes drying machine to effectively avoid obstacles during use.

[0060] In this embodiment, the obstacle refers to the ceiling. When the telescopic rod 30 is in the extended state and rises to the roof along with the drying rod 20, it will collide, squeeze, and rub against the ceiling, thereby damaging the telescopic rod 30. In addition, prolonged contact between the telescopic rod 30 and the ceiling can also cause current overload of the first drive mechanism 40, thereby damaging the first drive mechanism 40.

[0061] In this embodiment, the first action is an upward action, and the second action is a downward action. That is, when the drying rod 20 encounters an obstruction, the first drive mechanism 40 will drive the drying rod 20 to stop rising and descend a certain distance.

[0062] In this embodiment, when performing the second action, the movement distance of the drying rod 20 is between 50mm and 200mm. Within this range, it ensures that the drying rod 20 and the telescopic rod 30 are separated from the ceiling, while avoiding excessive descent of the drying rod 20 and the telescopic rod 30, which would not meet the user's needs.

[0063] In this embodiment, the control method further includes: if the current state of the telescopic rod 30 is the extended state, and it remains in the extended state after a first duration corresponding to the current time, controlling the second drive mechanism 50 to drive the telescopic rod 30 to retract.

[0064] In this embodiment, the first duration is 5s to 30s. That is, when the second position detection component 60 detects that the telescopic rod 30 remains in the extended state for 5s to 30s, if the user does not manually retract the telescopic rod 30, the clothes drying rack automatically controls the telescopic rod 30 to retract.

[0065] In this embodiment, the control method further includes issuing an alarm signal before the second drive mechanism 50 drives the telescopic rod 30 to retract. That is, before the clothes drying rack automatically retracts the telescopic rod 30, an alarm signal will be issued to the user to remind them to manually retract the telescopic rod 30 in a timely manner.

[0066] In this embodiment, the control method further includes: after issuing an alarm signal, if the clothes dryer receives an instruction to perform the first action, it controls the first drive mechanism 40 to stop and continues to issue a second alarm signal. Through the above control method, it is possible to automatically identify and not execute incorrect user instructions or misoperations, thus avoiding damage to the clothes dryer. In other words, to prevent user misoperation from causing the drying rod 20 to continue moving upwards by the first drive mechanism 40 even when the telescopic rod 30 has not been retracted, the clothes dryer in this embodiment is equipped with a protection mode. After the alarm component issues an alarm signal, if the user mistakenly selects an upward command, the clothes dryer can refuse to execute the command, avoiding damage to the clothes dryer, and will issue another alarm to remind the user to retract the telescopic rod 30.

[0067] In this embodiment, the control method further includes: after issuing a second alarm signal and for a first duration, if the telescopic rod 30 is still in the extended state, controlling the second drive mechanism 50 to drive the telescopic rod 30 to retract. That is, if the user does not manually retract the telescopic rod 30 5s to 30s after the alarm component issues a second alarm signal, the clothes dryer will automatically retract the telescopic rod 30 to avoid damage to the clothes dryer.

[0068] In this embodiment, the control method further includes: controlling the second drive mechanism 50 to retract the telescopic rod 30, and then controlling the first drive mechanism 40 to drive the drying rod 20 to perform a first action to the first upper limit position. It can be understood that the first upper limit position is the ideal clothes-drying height that the telescopic rod 30 can reach without contacting the ceiling. Specifically, if the user does not manually retract the telescopic rod 30 after a second alarm signal is issued, it means that the user is not near the clothes dryer or cannot perform the corresponding operation. In order to complete the drying of the clothes, the clothes dryer will directly drive the drying rod 20 and the telescopic rod 30 to rise to the preset ideal clothes-drying height position.

[0069] In this embodiment, the control method further includes: if the current state of the telescopic rod 30 is the extended state, and it switches to the retracted state within a first duration corresponding to the current moment, controlling the first drive mechanism 40 to drive the drying rod 20 to perform the first action. Specifically, if the telescopic rod 30 switches to the retracted state within the first duration, it means that the user has manually retracted the telescopic rod 30, indicating that the user is currently next to the clothes dryer and can perform corresponding operations, i.e., is in a state of actively controlling the clothes dryer. The clothes dryer will return the initiative to the user, causing the drying rod 20 and the telescopic rod 30 to rise to the height position required by the user under the user's action command, instead of directly driving the drying rod 20 and the telescopic rod 30 to rise to the preset ideal clothes drying height position to meet the user's current needs.

[0070] Of course, in an optional embodiment, the control method further includes: if the current state of the telescopic rod 30 is the retracted state, controlling the first drive mechanism 40 to drive the drying rod 20 to perform a first action to the first upper limit position. That is to say, whether the telescopic rod 30 has not yet extended or has automatically retracted, or the user has manually retracted the telescopic rod 30, there will be no situation where the telescopic rod 30 collides with the ceiling. Therefore, the drying rod 20 and the telescopic rod 30 can be directly raised to the ideal drying position for drying clothes.

[0071] In this embodiment, the control method further includes: after issuing a second alarm signal and for a first duration, if the current state of the telescopic rod 30 switches to the retracted state, controlling the first drive mechanism 40 to drive the drying rod 20 to perform the first action, while continuing to acquire the current state of the drying rod 20 and the current state of the telescopic rod 30. Similarly, if the telescopic rod 30 switches to the retracted state within the first duration, that is, the user manually retracts the telescopic rod 30, it means that the user is currently next to the clothes dryer and can perform corresponding operations, i.e., in a state of actively controlling the clothes dryer. The clothes dryer will return the initiative to the user, so that the drying rod 20 and the telescopic rod 30 rise to the height position required by the user's action command, instead of directly driving the drying rod 20 and the telescopic rod 30 to rise to the preset ideal clothes drying height position to meet the user's current needs. In addition, the clothes dryer will continue to monitor the current state of the drying rod 20 and the telescopic rod 30 to determine at any time whether the drying rod 20 encounters obstruction and whether the telescopic rod 30 is retracted.

[0072] In this embodiment, the control method further includes: after issuing an alarm signal, if the clothes drying machine receives an instruction to perform a second action, controlling the first drive mechanism 40 to drive the drying rod 20 to perform the second action. It is understood that the control method in this embodiment is designed to avoid collisions between the telescopic rod 30 and the ceiling in a timely manner. Therefore, when the user issues a descent command, the telescopic rod 30 can also separate from the ceiling, thus avoiding the ceiling, and the clothes drying machine will then execute the descent command. Furthermore, if the user then issues an ascending command, i.e., the clothes drying machine receives an instruction to perform the first action, the clothes drying machine will then execute that instruction.

[0073] In this embodiment, the control method further includes: after issuing an alarm signal, if the clothes drying machine receives any instructions other than the instructions to perform the first action and the instructions to perform the second action, executing the other instructions. It is understood that the aforementioned other instructions do not conflict with the up and down instructions, therefore the clothes drying machine will also execute the aforementioned instructions.

[0074] In this embodiment, the control method further includes: determining a first determination condition in real time during the execution of the first action by the drying rod 20; if the first determination condition is met, determining that the current state of the drying rod 20 is an obstructed state. The first determination condition includes the current change value of the first drive mechanism 40; if the current change value is greater than a first preset value, determining that the current state of the drying rod 20 is an obstructed state.

[0075] It should be noted that the travel distance of the clothes drying rack in this embodiment is fixed, and the weight of the clothes drying on the drying rod 20 and the telescopic rod 30 is proportional to the current of the first drive mechanism 40; that is, a certain weight corresponds to a certain current. The current detection component actually detects the current value of the first drive mechanism 40 and compares it with the current reference value of the current state. The deviation between the two is the current change value. When the current change value is too large and exceeds the preset value, it is determined that the telescopic rod 30 has encountered an obstacle, that is, reached the ceiling.

[0076] In this embodiment, the first preset value is between 0.2A and 0.4A. Within this range, changes in the current of the first drive mechanism 40 can be detected without causing current overload of the first drive mechanism 40.

[0077] In one optional embodiment, the first determination condition includes the distance between the drying rod 20 and the ceiling. If the distance is less than a second preset value, the current state of the drying rod 20 is determined to be an obstructed state.

[0078] In this embodiment, the control method further includes: acquiring the current value of the first drive mechanism 40; if the current state of the telescopic rod 30 is the extended state and the current value is the first current, controlling the second drive mechanism 50 to drive the telescopic rod 30 to retract; if the current state of the telescopic rod 30 is the extended state and the current value is the second current, controlling the second drive mechanism 50 to drive the telescopic rod 30 to retract; and controlling the first drive mechanism 40 to drive the drying rod 20 to perform a first action to the first upper limit position, wherein the second current is greater than the first current.

[0079] Specifically, in this embodiment, the first current is the no-load current, and the second current is the loaded current. The no-load current refers to the current in the first drive mechanism 40 during the upward movement of the clothes drying rack when no clothes are hanging on the drying rod 20 and telescopic rod 30; the loaded current refers to the current in the first drive mechanism 40 during the upward movement of the clothes drying rack when clothes are hanging on the drying rod 20 and telescopic rod 30. In other words, during the use of the clothes drying rack, while the second position detection component 60 detects whether the telescopic rod 30 has retracted, the current detection component also detects and determines whether clothes are being dried on the clothes drying rack.

[0080] like Figure 3 As shown, in one specific embodiment, the specific control process of the clothes drying rack is as follows:

[0081] During the process of the lifting motor driving the drying rod 20 and telescopic rod 30 to rise, the current detection component collects the current value and current change value of the lifting motor in real time, i.e., the dynamic obstacle detection real-time value. The current value is more accurate after being filtered by the filtering component. After confirming the preset value, i.e., the dynamic obstacle detection comparison value, the dynamic obstacle detection real-time value is compared with the dynamic obstacle detection comparison value. When the dynamic obstacle detection real-time value exceeds the dynamic obstacle detection comparison value, it is determined that the drying rod 20 is obstructed, i.e., dynamic obstacle detection is triggered. At this time, the lifting motor will drive the drying rod 20 and telescopic rod 30 to descend 100mm to avoid the obstacle, and at the same time send an alarm signal to the user to remind the user to manually retract the telescopic rod 30. If the user issues a rise command to the clothes drying machine at this time, the clothes drying machine will not execute the rise command but will send an alarm signal again to remind the user to manually retract the telescopic rod 30. After waiting for X seconds, if the user still does not manually retract the telescopic rod 30, the clothes drying machine will automatically retract the telescopic rod 30, where X is 5 to 30. After automatically retracting the telescopic rod 30, the clothes drying machine will directly raise the drying rod 20 and telescopic rod 30 to the ideal clothes drying height position. If the user manually retracts the telescopic rod 30 in time, the clothes drying rack will continue to rise until the user issues a stop command, at which point the drying rod 20 and telescopic rod 30 will stop at that height. If the user then issues a lowering command, the clothes drying rack will lower itself; if the user then issues an upward command, the clothes drying rack will also rise. If the user issues any other command besides rising or lowering, the clothes drying rack will execute that command accordingly.

[0082] As can be seen from the above description, the above-described embodiments of the present invention achieve the following technical effects: By using the above-described control method for the clothes drying machine, the current state of the drying rod 20 and the telescopic rod 30 is obtained, and the actions of the first drive mechanism 40 and the second drive mechanism 50 are controlled accordingly. When the drying rod 20 is in an obstructed state, the drying rod 20 is driven to reverse its movement, and when the telescopic rod 30 is in an extended state, the telescopic rod 30 is driven to retract. This avoids situations where the drying rod 20 encounters obstruction during the clothes drying process, leading to current overload, and the telescopic rod 30 is squeezed and expanded by obstacles, thereby damaging the clothes drying machine. This allows the clothes drying machine to effectively avoid obstacles during use.
