Description

Technical Field

[0001] This application relates to the field of clothes drying control technology, specifically to clothes drying machines and their drying rod control systems. Background Technology

[0002] Smart clothes drying racks are gaining popularity due to their ability to automatically raise and lower, and the integration of functions such as lighting, drying, and sterilization. They have become an indispensable part of smart home products.

[0003] To monitor the status of clothes drying rack components, such as whether clothes are hanging on the rack, whether telescopic racks are in a telescopic or retracted state, and whether quilt drying racks are in an extended or retracted state, existing technologies generally use two methods. The first is manual observation, where the user judges whether clothes are drying on the rack. When the user determines that there are no clothes drying on the rack, they can further control the rack to rise to a higher position via remote control or a terminal APP. This control method is inconvenient for users and is prone to misoperation, which can cause the rack to interfere with the ceiling or damage the clothes drying rack. Another type is the automatic control method, where the clothes drying machine automatically determines whether there are clothes drying on the drying rod. This is usually achieved by installing electronic sensors on the drying rod, such as clothing recognition sensors, limit switches, and micro switches. The main unit of the clothes drying machine determines the status of the drying rod based on the signals detected by the electronic sensors. For example, if the electronic sensor determines that there are no clothes drying on the drying rod, it can further control the drying rod to rise to the drying position. Otherwise, the drying rod can only rise to the drying position. This method makes the control of the clothes drying machine more convenient, but it requires power supply at the drying rod end, increasing the complexity of design and maintenance.

[0031] Preferably, it also includes a position detection unit;

[0032] The position detection unit is connected to the control unit and is used to detect the position information of the drying rack assembly in the lifting direction, so that the control unit can activate the electronic tag sensing unit when the drying rack assembly reaches the second preset position based on the position information.

[0033] The second objective of this invention is achieved through the following technical solution: a clothes drying rack, including the drying rod control system described in the first objective of this invention. This invention has the following advantages and effects compared to the prior art:

[0034] (1) In this utility model, there are control units, electronic tag sensing units, electronic tags and switch units; wherein, the switch unit set on the drying rod assembly can open and close based on the state of the drying rod assembly, and further change the state of the electronic tag on the drying rod assembly. The state of the electronic tag can be sensed by the electronic tag sensing unit on the host and fed back to the control unit. Based on this, the control unit can determine the state of the drying rod assembly according to the information fed back by the electronic tag sensing unit, and thus control the drying rod assembly to perform corresponding operations, such as lifting and lowering operations. In the system of this invention, the electronic tag set on the drying rod assembly can be energized based on the electromagnetic waves sent by the electronic tag sensing unit. The opening and closing state of the switch unit can control the on and off of the electronic tag circuit, that is, control whether the electronic tag sends information to the electronic tag sensing unit. The electronic tag sensing unit can determine the state of the electronic tag according to whether it receives information, and thus further determine the state of the drying rod assembly and / or control the clothes dryer to perform corresponding operations. The setting of the switch unit in the system of this invention can automatically realize the monitoring of the hanging state of the drying rod assembly, and ensure the safety of the drying rod assembly storage.

[0035] (2) In this utility model, the switch unit includes a first switch unit, which includes a first switch element disposed at each hanging position of the drying rod assembly and which can be triggered to change the opening and closing state when clothes are hung at the hanging position; wherein each first switch element is connected in series or in parallel and disposed in the electronic tag circuit; based on this, when clothes are hung at one of the hanging positions of the drying rod assembly, the first switch element will be triggered, thereby changing the state of the electronic tag. Based on the state of the electronic tag, the control unit can confirm whether clothes are hung on the drying rod assembly, thereby determining the state of the drying rod assembly, and further determining whether the drying rod assembly meets the preset conditions (conditions). If clothes are hung, the preset conditions are not met, and the drying rod assembly is not controlled to rise to the first preset position (e.g., the gear position or the upper limit position). Therefore, the setting of the switch unit in the system of this invention can automatically realize the monitoring of the hanging state of the drying rod assembly and ensure the safety of the drying rod assembly.

[0036] (3) In this utility model, when the drying rod assembly includes a first drying rod that is telescopic in the length direction, the switch unit also includes a second switch unit. The second switch unit is connected in series or in parallel with the first switch unit and is set in the electronic tag circuit. The second switch unit includes a second switch element that can be triggered to change the opening and closing state when the first drying rod is in the retracted state. Based on this, when the first drying rod is retracted, the second switch element will be triggered. Since the opening and closing state of the second switch element can change the state of the electronic tag, the control unit can confirm whether the first drying rod is in the retracted state based on the state of the electronic tag. This can prevent the drying rod from colliding with the ceiling or ceiling when it rises to the upper limit position or position without retracting, and further ensure the safety of the clothes drying machine.

[0037] (4) In this invention, when the drying rod assembly includes a second drying rod that can be retracted or extended, such as a quilt drying rod; the switch unit also includes a third unit, which is connected in series or in parallel with the first switch unit and is set in the electronic tag circuit; the third switch unit includes a third switch element that is set on the drying rod assembly and can be triggered to change the opening and closing state when the second drying rod is in the retracted state; based on this, when the second drying rod is in the retracted position, the third switch element can be triggered. Since the opening and closing of the third switch element can change the state of the electronic tag, the control unit can confirm whether the third drying rod is in the retracted state based on the state of the electronic tag, thereby further avoiding the situation where the clothes drying rack quilt drying rod collides with the ceiling or ceiling due to not being retracted, and further ensuring the safety of using the clothes drying rack.

[0038] (5) In this utility model, the first switch, the second switch and the third switch can all be normally closed or normally open. When the first switch is normally closed and the second and third switches are normally open, the electronic sensing unit can determine that the electronic tag is in the first state when it receives the tag information (that is, the electronic tag circuit is on), and thus determine that the condition is met. This setting method can make the detection accuracy higher. Compared with the situation where the electronic sensing unit determines that the electronic tag is in the first state when it does not receive the tag information, it can avoid other uncontrollable situations that cause the electronic tag to not be on and the drying rack to be in the preset state.

[0039] (6) In this utility model, when there are multiple electronic tags, the electronic tag sensing unit is set to one or more, wherein each electronic tag sensing unit senses the tag information of multiple electronic tags. Based on this, the number of electronic tag sensing units used can be effectively reduced, and the equipment manufacturing cost can be reduced.

[0040] (7) The present invention also includes a position detection unit, which is connected to the control unit and is used to detect whether the drying rod assembly has reached the second preset position (which may be the drying gear information) in the lifting direction. When the position is reached, the control unit controls the electronic tag sensing unit to turn on and read the electronic tag information. Based on this, the present invention can realize that the electronic tag sensing unit is turned on only when the electronic tag on the drying rod assembly is a short distance away from the electronic tag sensing unit, which effectively reduces the power consumption of the electronic tag sensing unit and makes the clothes drying machine more energy-saving and environmentally friendly.

[0045] The embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions of the embodiments of this application.

[0046] Example 1

[0047] Currently, the status monitoring of clothes drying rack components generally relies on manual observation or automatic monitoring. Manual observation is inconvenient for users and is prone to misoperation. On the other hand, current automatic monitoring generally uses electronic sensors installed on the drying rack that require power, which increases the complexity of design and maintenance.

[0048] Based on the problems existing in the prior art, this embodiment provides a clothes drying rack control system. This control system is applied to a clothes drying rack and can automatically monitor the status of the drying rack when it is not powered on. This avoids the complex design of the clothes drying rack structure, making the maintenance of the clothes drying rack simpler. Moreover, the design of the drying rack not being powered on also makes the operation of the clothes drying rack safer.

[0049] The clothes drying rack referred to in this embodiment generally includes a main unit and a drying rod assembly. The main unit is generally installed on the ceiling, and the drying rod assembly is set below the main unit by steel wire rope or other lifting components. The drying rod assembly generally includes one or more clothes drying rods for drying clothes, one or more quilt drying rods for drying bedding, and one or more horizontal rods for drying small items (underwear, socks, towels, etc.). Clothes of general size are usually hung on the clothes drying rods, quilt drying rods, or small drying rods using clothing hangers (such as clothes hangers). The main unit contains a main controller, drive unit, and other components. The drive unit of the clothes drying rack may include a motor, reel, pulley assembly, and steel wire rope. The main controller is connected to the motor via a motor driver to control the motor's rotation. The reel is driven by the motor's output shaft. One end of the steel wire rope is mounted on the reel, and the other end passes through a pulley in the pulley assembly to change direction (from horizontal to vertical) and is fixedly connected to the drying rod assembly below the main unit. The reel rotates under the motor's drive to wind up and unwind the steel wire rope, thereby causing the drying rod assembly on the steel wire rope to move up or down. Additionally, the clothes drying rack may be equipped with lighting, drying, and disinfection modules, which can be controlled by commands issued by the main controller on the main unit.

[0050] like Figure 1 As shown in the figure, the drying rack control system in this embodiment includes a control unit, an electronic tag sensing unit, an electronic tag, and a switch unit; specifically:

[0051] In this embodiment, a switch unit is installed on the clothes drying rack assembly, triggering the opening and closing state based on the state of the drying rack assembly. The switch unit can be installed at multiple locations on the drying rack assembly, including but not limited to: the clothes hanging position, the first drying rack (as a main drying rack), and the second drying rack (as a quilt drying rack). The switch unit is configured to be triggered when the state of the drying rack assembly changes, thus providing feedback on the corresponding state of the drying rack assembly.

[0052] In this embodiment, an electronic tag is mounted on the drying rack assembly and connected to a switching unit. The state of the electronic tag can be controlled by the opening and closing state of the switching unit. In this embodiment, the electronic tag can be an RFID (Radio Frequency Identification) passive tag, which includes an RFID transmitting chip and an antenna. The corresponding electronic tag sensing unit uses an RFID detector, which includes an RFID transceiver chip and an antenna. The detection principle between the two is as follows: the RFID detector emits electromagnetic waves, and the coil inside the RFID passive tag receives the electromagnetic waves and generates a weak current to power the RFID transmitting chip inside the tag. After the chip inside the RFID passive tag is powered, it can emit electromagnetic waves carrying its own information through the antenna. The RFID detector's RFID transceiver chip can receive the electromagnetic wave information sent by the RFID passive tag through the antenna and analyze the corresponding tag information. In this embodiment, the number of electronic tags is set to one or more, depending on actual needs. In this embodiment, the switching unit is set in the circuit between the electronic tag's RFID transmitting chip and the power generation coil. The state of the switching unit can control whether the RFID transmitting chip is powered, thereby controlling the state of the electronic tag.

[0053] In this embodiment, the electronic tag sensing unit is installed on the clothes drying rack main unit and connected to the control unit, used to feed back information about the electronic tag status to the control unit. In this embodiment, the electronic tag sensing unit is positioned to detect the electronic tags installed on the drying rack assembly. When the electronic tag sensing unit is an RFID detector, the radio frequency transceiver chip is connected to the control unit and can determine the current status of the electronic tag based on whether it receives tag information sent by the electronic tag, including a first status and a second status. When tag information is received, the electronic tag is determined to be in the first status, i.e., the radio frequency transceiver chip is powered on and in a working state. When tag information is not received, the electronic tag is determined to be in the second status, i.e., the radio frequency transceiver chip is powered off and in a non-working state.

[0054] In this embodiment, the control unit can determine the status of the drying rack assembly and / or control the clothes dryer to perform corresponding operations based on the information fed back by the electronic tag sensing unit. After determining the status of the drying rack assembly, it can be determined whether the drying rack assembly is in a preset state.

[0055] In this embodiment, the control unit is connected to the drive unit of the clothes drying rack assembly. After the control unit determines the state of the clothes drying rack assembly based on the feedback information from the electronic tag sensing unit, it can further determine whether the clothes drying rack assembly meets preset conditions. If the conditions are met, the control unit controls the clothes drying rack assembly to perform the corresponding operation. Alternatively, after receiving the feedback information from the electronic tag sensing unit, the control unit can directly control the clothes drying machine to perform the corresponding operation or determine whether the clothes drying rack assembly meets preset conditions based on the feedback information from the electronic tag sensing unit. If the preset conditions are met, the control unit controls the clothes drying machine to perform the corresponding operation.

[0056] It should be noted that for some clothes drying racks, such as those with built-in installation, the installation method can hide the clothes drying rack inside the ceiling or inside the rack housing. This type of clothes drying rack usually includes a drying mode and a storage mode (usually the upper limit). The storage mode is located above the drying mode. When the clothes drying rack is in the storage mode, the drying rod can be retracted and hidden. During use, when there are clothes drying on the drying rod, the rod can be controlled to rise only to the drying mode. When there are no clothes drying on the drying rod, the rod can be controlled to rise to the drying mode. In this embodiment, for the above-mentioned type of clothes drying rack, it can be determined whether the drying rod assembly meets the preset conditions based on the state of the drying rod assembly or the feedback information from the electronic tag sensing unit. The preset conditions are the storage conditions. When the state of the drying rod assembly is the preset state or when the preset information is received from the electronic tag sensing unit, it can be determined that the storage conditions are met. Therefore, when controlling the drying rod assembly to rise, it can be controlled to rise to the first preset position. The first preset position refers to the upper limit position or storage position of the clothes drying rack. When the drying rod assembly reaches this position, it can be hidden inside the ceiling or the clothes drying rack housing.

[0057] In this embodiment, the control unit can be a microcontroller chip such as an MCU, specifically the main controller on the clothes drying rack host, or a controller set in the RFID detector and connected to the main controller on the clothes drying rack host, such as a microcontroller embedded in the RFID detector. Correspondingly, the control unit is directly or indirectly connected to the drive unit of the drying rod assembly through the main controller. If the control unit is the latter, after determining the state of the drying rod assembly, the control unit sends the result information to the main controller of the clothes drying rack host, and the main controller of the clothes drying rack host controls the drying rod assembly based on the result information. Alternatively, the control unit directly sends the received feedback information to the main controller, and the main controller determines the state of the drying rod assembly based on the received feedback information.

[0058] In this embodiment, the feedback information of the electronic tag sensing unit includes first feedback information and second feedback information. When the electronic tag sensing unit determines that the electronic tag is in a first state, it can send the first feedback information to the control unit. When the electronic tag sensing unit determines that the electronic tag is in a second state, it can send the second feedback information to the control unit. When the control unit receives the first feedback information, it determines that the drying rod assembly is in a preset state and can control the drying rod assembly to perform corresponding operations, such as rising to the upper limit position or the storage position. When the control unit receives the second feedback information, it determines that the drying rod assembly is not in a preset state and can control the drying rod assembly to perform corresponding operations, such as stopping before rising to the upper limit position or the storage position. Alternatively, when the control unit receives the first feedback information, it directly controls the clothes dryer to perform the first operation, and when the control unit receives the second feedback information, it directly controls the clothes dryer to perform the second operation.

[0059] In this embodiment, the state of the electronic tag includes the state in which the electronic tag circuit is conducting and transmitting tag information, and the state in which the electronic tag circuit is not conducting and does not transmit any information. In this embodiment, the first state and the second state of the electronic tag can be determined by setting the connection relationship of the switching unit in the electronic tag circuit (e.g., series or parallel relationship) and the type of the switching unit (normally closed and normally open).

[0060] In this embodiment, the switching unit includes a first switching unit, which includes a first switch element disposed at each hanging position of the drying rod assembly and which can be triggered to change the opening and closing state when clothes are hung at the hanging position; each of the first switch elements is disposed in series or in parallel in the corresponding electronic tag circuit, or each of the first switch elements is disposed separately in each electronic tag circuit.

[0061] In this embodiment, the number of electronic tags can be one or more. When there is only one, each first switch is connected in series or in parallel to form an electronic tag circuit. When there are multiple electronic tags, each electronic tag circuit can have one first switch or multiple first switches connected in series or in parallel.

[0062] When none of the first switches in the electronic tag circuit are triggered (i.e., when no clothes are hung in any of the hanging positions), the state of each first switch causes the electronic tag to enter a first state. When one or more of the first switches are triggered (i.e., when clothes are hung in one or more of the hanging positions), the state of each first switch causes the electronic tag to enter a second state. The specific settings can be as follows: The first switch can be a normally closed switch. The states of the first switch at each hanging position are as follows: When no clothes are hung, the first switch is closed, the electronic tag circuit is open, and tag information can be sent to the electronic tag sensing unit. When clothes are hung, the first switch is open, the electronic tag circuit is closed, and tag information cannot be sent to the electronic tag sensing unit. Therefore, in the above case, it can be set to determine that the electronic tag is in the first state when electronic tag information is received, otherwise it is in the second state. Alternatively, the first switch can also be a normally open switch. In this case, the states of the first switch at each hanging position are as follows: When no clothes are hung, the first switch is open, the electronic tag circuit is closed, and tag information cannot be sent to the electronic tag sensing unit. When clothes are hung, the first switch is closed, the electronic tag circuit is open, and tag information can be sent to the electronic tag sensing unit. Therefore, in the above case, it can be set to determine that the electronic tag is in the first state when electronic tag information cannot be received, otherwise it is in the second state.

[0063] Based on the switch unit configuration described above in this embodiment, the preset state of the drying rod assembly can be set to: the drying rod assembly is in an un-clothed state. Specifically:

[0064] like Figure 2a As shown, if the first switch is a normally closed switch and multiple first switches are provided in the electronic tag circuit, then the first switches in the same electronic tag circuit are connected in series. When no clothes are hung at the hanging positions of each first switch, the electronic tag circuit is conductive; when clothes are hung at one or more of the hanging positions of the first switches, the first switch at the corresponding hanging position is disconnected, and the electronic tag circuit is not conductive. In the above case, this embodiment can set the electronic tag circuit to conductive as the first state of the electronic tag, at which time the electronic tag sensing unit can receive tag information; the electronic tag circuit to disconnect as the second state, at which time the electronic tag sensing unit cannot receive tag information. Therefore, under the aforementioned first switch type and connection relationship, if the electronic tag sensing unit receives tag information, it determines that the electronic tag is in the first state, and thus sends the first feedback information to the control unit. Upon receiving the first feedback information, the control unit can confirm that no clothes are hanging on the drying rack assembly, that is, it determines that the drying rack assembly is in the preset state. If the electronic tag sensing unit does not receive tag information, it determines that the electronic tag is in the second state, and thus sends the second feedback information to the control unit. Upon receiving the second feedback information, the control unit can confirm that clothes are hanging on the drying rack assembly, that is, it determines that the drying rack assembly is not in the preset state.

[0065] like Figure 2b As shown, if the first switch is a normally open switch and multiple first switches are provided in the electronic tag circuit, then the first switches in the same electronic tag circuit are connected in parallel. When no clothes are hung at the hanging positions of each first switch, the electronic tag circuit is not conductive. When clothes are hung at one or more of the hanging positions of the first switches, the corresponding first switch closes, and the electronic tag circuit is conductive. In the above case, this embodiment can set the electronic tag circuit to be non-conductive, i.e., disconnected, as the first state of the electronic tag. At this time, the electronic tag sensing unit may not receive tag information. The electronic tag circuit is then set to be conductive, i.e., in the second state, where the electronic tag sensing unit can receive tag information. Therefore, under the aforementioned first switch type and connection relationship, if the electronic tag sensing unit cannot receive tag information, it determines that the electronic tag is in the first state, and thus sends the first feedback information to the control unit. Upon receiving the first feedback information, the control unit can confirm that no clothes are hanging on the drying rack assembly, that is, it determines that the drying rack assembly is in the preset state. If the electronic tag sensing unit receives tag information, it determines that the electronic tag is in the second state, and thus sends the second feedback information to the control unit. Upon receiving the second feedback information, the control unit can confirm that clothes are hanging on the drying rack assembly, that is, it determines that the drying rack assembly is not in the preset state.

[0066] In this embodiment, when all the first switches are normally closed switches connected in series, the electronic tag path is only activated when there are no clothes hanging at any of the hanging positions, i.e., when no clothes are hanging on the drying rod assembly. In other cases, the path is not activated. Therefore, when the electronic tag is determined to be in the first state (i.e., when the first feedback information is received), it is determined that no clothes are hanging at the corresponding hanging positions. If all the first switches are in one electronic tag circuit, the drying rod assembly can be determined to be in a preset state. Conversely, when all the first switches are normally open switches connected in parallel, the electronic tag path is only deactivated when there are no clothes hanging at any of the hanging positions, i.e., it is activated in other cases. Therefore, when the electronic tag is determined to be in the second state (i.e., when the second feedback information is received), it is determined that no clothes are hanging at the corresponding hanging positions. If all the first switches are in one electronic tag circuit, the drying rod assembly can be determined to be in a preset state.

[0067] In this embodiment, when multiple electronic tags are included, if the electronic tag sensing unit determines that each electronic tag is in a first state, the control unit can determine that the drying rack assembly is in a preset state based on the information fed back by the electronic tag sensing unit. If one or more electronic tags are in a second state, the control unit determines that the drying rack assembly is not in a preset state based on the information fed back by the electronic tag sensing unit.

[0068] In this embodiment, the electronic tag circuit is defined as follows: First case: all first switches in each electronic tag circuit are normally closed switches and when there are multiple first switches, the switches are connected in series; Second case: all first switches in each electronic tag circuit are normally open switches and when there are multiple first switches, the switches are connected in parallel; Third case: in the first electronic tag circuit (one or more electronic tags), all first switches are normally closed switches and when there are multiple first switches, the switches are connected in series; in the second electronic tag circuit (one or more electronic tags), all first switches are normally open switches and when there are multiple first switches, the switches are connected in parallel.

[0069] In this embodiment, the electronic tag sensing unit determines the electronic tag status based on the above-mentioned method, specifically:

[0070] If there are multiple electronic tags and the first condition is met, the electronic tag sensing unit determines that the corresponding electronic tag is in the first state when it receives the tag information of the corresponding electronic tag, and determines that the corresponding electronic tag is in the second state when it does not receive the tag information of the corresponding electronic tag.

[0071] If there are multiple electronic tags and the second condition is met, then when the electronic tag sensing unit does not receive the tag information of the corresponding electronic tag, it determines that the corresponding electronic tag is in the first state; when the electronic tag sensing unit receives the tag information of the corresponding electronic tag, it determines that the corresponding electronic tag is in the second state.

[0072] If there are multiple electronic tags and the third condition is met, then for the first electronic tag, if the electronic tag sensing unit receives the tag information it sends, it is determined to be in the first state; otherwise, it is determined to be in the second state. For the second electronic tag, if the electronic tag sensing unit does not receive the tag information it sends, it is determined to be in the first state; otherwise, it is determined to be in the second state. For example, the first switch of the drying rack assembly is divided into two groups. The first group of first switches are normally closed switches and are connected in series in the first electronic tag circuit. When there is no clothing hanging at the corresponding hanging position of each first switch in the first group, the first electronic tag is in the first state. When there is no clothing hanging at the corresponding hanging position of each first switch in the second group, the second electronic tag is in the first state. At this time, the electronic tag sensing unit feeds back the first feedback information to the control unit, so it can be determined that the drying rack assembly is in the preset state. When one or more of the first switches in the first group have clothes hanging at their corresponding hanging positions, the first electronic tag is in the second state. When one or more of the first switches in the second group have clothes hanging at their corresponding hanging positions, the second electronic tag is in the second state. If the electronic tag sensing unit detects that one of the first and second electronic tags is in the second state, one of the information fed back to the control unit is the second feedback information. The control unit can then determine that the drying rack assembly is not in the preset state.

[0073] In this implementation, when the same electronic tag sensing unit is responsible for sensing multiple electronic tags, after determining the state of each electronic tag, the electronic tag sensing unit can provide feedback information based on the state of each electronic tag. Specifically, when all electronic tags are in the first state, a first feedback message is issued. Upon receiving the first feedback message, the drying rack assembly is determined to be in a preset state, meeting the storage conditions. Therefore, upon receiving a raising command, the drying rack assembly can be raised to the upper limit position or the storage position. If any of the multiple electronic tags are in the second state, the electronic tag sensing unit issues a second feedback message. Upon receiving the second feedback message, the control unit determines that the drying rack assembly is not in the preset state, i.e., does not meet the preset conditions. Therefore, upon receiving a raising command, the drying rack assembly cannot be raised to the upper limit position or the storage position. Of course, in this embodiment, when each electronic tag sensing unit is used to sense multiple electronic tags, it can also send multiple feedback messages to the control unit. This can be achieved through communication with different ports of the control unit.

[0074] When multiple electronic tags share a single electronic tag sensing unit, the electronic tag sensing unit can compare the tag information of all the electronic tags it stores. By comparing the received tag information with the stored tag information, it can determine which electronic tag the tag information received by the electronic tag sensing unit comes from, and which electronic tag has not sent tag information, thereby determining the status of each electronic tag. Based on this, the number of electronic tag sensing units used can be effectively reduced, thus lowering the equipment manufacturing cost.

[0075] In this embodiment, when there are multiple electronic tags, one or more electronic tag sensing units can be set based on the position of each electronic tag. When multiple electronic tag sensing units are included, each electronic tag sensing unit sends out first feedback information or second feedback information after the electronic tag is in a certain state. The control unit determines the state of the drying rack assembly based on the feedback information fed back by each electronic tag sensing unit. Specifically, when all electronic tag sensing units feed back the first feedback information, it can be determined that the drying rack assembly is in a preset state. When an electronic tag sensing unit feeds back the second feedback information, it can be determined that the drying rack assembly is not in a preset state.

[0076] This implementation also includes a position detection unit connected to the control unit. This unit detects the position information of the drying rack assembly in the lifting direction, allowing the control unit to activate the electronic tag sensing unit when the drying rack assembly reaches the second preset position. In this embodiment, the position detection unit can use a Hall sensor. The Hall sensor detects the number of motor rotations. Based on the number of motor rotations and the travel of the drying rack assembly per rotation, the total travel of the drying rack assembly can be determined, thus determining the current position. During the rising process of the drying rack assembly, the position detection unit continuously monitors its position to determine if it has reached the second preset position. If it has, the electronic tag sensing unit is activated. The electronic tag sensing unit senses the tag information of the electronic tag to determine its state. If the initial electronic tag is in the first state, the current drying rack assembly is in the preset state, meeting the storage conditions. Therefore, the drying rack assembly can be controlled to continue rising to the upper limit or storage position. If the initial electronic tag is in the second state, the drying rack assembly is not in the preset state and does not meet the storage conditions. Therefore, the drying rack assembly is controlled to stop immediately.

[0077] In this embodiment, the electronic tag on the drying rod assembly is energized by electromagnetic waves emitted by the electronic tag sensing unit. The opening and closing state of the switch unit controls the on / off state of the electronic tag circuit, i.e., whether the electronic tag sends information to the electronic tag sensing unit. The electronic tag sensing unit determines the state of the electronic tag based on whether it receives information, and then feeds back first feedback information to the control unit. After receiving the first feedback information, the control unit determines that the drying rod assembly is in a preset state, and then can control the clothes dryer accordingly based on this state. For example, in this embodiment, the preset state indicates that no clothes are hung on the drying rod assembly, which meets the storage conditions of the drying rod. Therefore, when the clothes dryer rises control command is received, the drying rod assembly is controlled to rise directly to the first preset position, such as the upper limit. Considering that in this embodiment, different states of the drying rod assembly will cause the electronic tag sensing unit to feed back first feedback information to the control unit after acting on the switch unit, the control unit can be set to control the drying rod assembly to rise directly to the first preset position after receiving the first feedback information and if it receives the clothes dryer rise control command, in order to achieve storage.

[0078] Therefore, the system of this embodiment can determine the state of the clothes drying rack assembly even when it is not powered on, thereby achieving automatic control of the drying rack. Specifically, in this embodiment, the system includes a first switch component installed at each hanging position of the clothes drying rack assembly. Based on the first switch component and the connected electronic tag, the system of this embodiment can automatically monitor the hanging status of the clothes drying rack assembly and automatically control the clothes drying machine, effectively ensuring the safety of the clothes drying rack assembly.

[0079] Example 2

[0080] This embodiment discloses a drying rod control system. The only difference between this embodiment and embodiment 1 is that the switching unit in this embodiment further includes a second switching unit; the drying rod assembly includes a first drying rod that is telescopic in the length direction.

[0081] In this embodiment, the second switch unit is connected in series or in parallel with the first switch unit and then set in the electronic tag circuit; or, the second switch unit is set in the electronic tag circuit alone, that is, the first switch unit and the second switch unit are set in different electronic tag circuits respectively.

[0082] In this embodiment, the second switch unit includes a second switch element disposed on the drying rod assembly and triggered to change its opening / closing state when the first drying rod is in a retracted state. The first drying rod includes a main drying rod and a first telescopic rod and a second telescopic rod disposed at both ends of the main drying rod. The second switch elements can be respectively disposed at the positions where the main drying rod contacts the first and second telescopic rods when fully retracted. Specifically, the second switch elements can be disposed on the main drying rod, on the first and second telescopic rods, or at other positions on the drying rod assembly; this embodiment does not impose specific limitations, as long as the second switch element at the corresponding position can be triggered when the first and second telescopic rods are fully retracted. In this embodiment, one or more second switch elements can be disposed on both sides of the main drying rod, that is, the number of second switch elements is two or more.

[0083] In this embodiment, each second switch can be set in a different electronic tag circuit, or it can be set in the same electronic tag circuit after being connected in series or in parallel; each second switch can also be set in the same electronic tag circuit after being connected in series or in parallel with each first switch in the first switch unit.

[0084] In this embodiment, each second switch can be either a normally open switch or a normally closed switch. When the second switch is a normally open switch, it is closed when the first drying rod is fully retracted; otherwise, it is open. When the second switch is a normally closed switch, it is open when the first drying rod is fully retracted; otherwise, it is closed. In this embodiment, when the second switch is a normally open switch and the electronic tag circuit includes multiple second switches, the second switches in the electronic tag circuit are connected in series; when the first switch is a normally closed switch and the electronic tag circuit includes multiple first switches, the first switches in the electronic tag circuit are connected in parallel. When the electronic tag circuit includes a first switch unit and a second switch unit, if the first switch is a normally closed switch and the second switch is a normally open switch, the first switch unit and the second switch unit are connected in series; if the electronic tag circuit includes a first switch unit and a second switch unit, if the first switch is a normally open switch and the second switch is a normally closed switch, the first switch unit and the second switch unit are connected in parallel.

[0085] In this embodiment, when none of the first switching elements are triggered and the second switching element is triggered, the states of the first and second switching elements cause the electronic tag to enter a first state; when one or more of the first switching elements are triggered, and / or the second switching element is not triggered, the states of the first and second switching elements cause the electronic tag to enter a second state. Wherein, when the same electronic tag circuit includes a first switching unit and a second switching unit, the first switching element can be selected as a normally closed switch and the second switching element as a normally open switch, or the first switching element can be selected as a normally open switch and the second switching element as a normally closed switch.

[0086] Based on the settings of the switching unit described above in this embodiment, the preset state of the drying rod assembly can be set as follows: the drying rod assembly is in an unclothed state and the first drying rod is in a retracted state. Specifically:

[0087] When the first switching element is a normally closed switch and the second switching element is a normally open switch, then in the x-circuit of the electronic tag circuit, as follows: Figure 3a As shown, each first switch and each second switch are connected in series in the circuit. Based on this, when no clothes are hanging at any of the hanging positions on the drying rack assembly and the first drying rack is fully retracted, the electronic tag x circuit is activated. At this time, the electronic tag sensing unit can receive the tag information sent by the electronic tag x, determine that the electronic tag x is in the first state, and therefore sends the first feedback information to the control unit. When the control unit receives the first feedback information, it can determine that no clothes are hanging at any of the hanging positions on the drying rack assembly and the first drying rack is fully retracted, and therefore determines that the drying rack assembly is in the preset state. When clothes are hung at one or more of the hanging positions, the first switch at the corresponding hanging position is disconnected. When one of the first telescopic rods or the second telescopic rod of the first drying rack is not fully retracted, the corresponding second switch is disconnected. Therefore, in the above situation, the electronic tag x circuit is not activated. At this time, the electronic tag sensing unit cannot receive the tag information sent by the electronic tag x, determine that the electronic tag x is in the second state, and therefore sends the second feedback information to the control unit. When the control unit receives the second feedback information, it can determine that the clothes hanging on the drying rack assembly and / or the first drying rack is not fully retracted, and therefore determines that the drying rack assembly is not in the preset state.

[0088] When the first switching element is a normally open switch and the second switching element is a normally closed switch, then in the electronic tag y-circuit, if... Figure 3bAs shown, each first switch and each second switch are connected in parallel in the circuit. Based on this, when no clothes are hanging at any of the hanging positions on the drying rack assembly and the first drying rack is fully retracted, the electronic tag y circuit is not conductive. In this case, the electronic tag sensing unit cannot receive the tag information sent by electronic tag y, determining that electronic tag y is in the first state. Therefore, it sends first feedback information to the control unit. Upon receiving the first feedback information, the control unit can determine that no clothes are hanging at any of the hanging positions on the drying rack assembly and that the first drying rack is fully retracted, thus determining that the drying rack assembly is in the preset state. When clothes are hung on one or more of the hanging positions, the first switch at the corresponding hanging position closes. When one of the first telescopic rods or the second telescopic rod of the first drying rod is not fully retracted, the corresponding second switch closes. In the above situation, the electronic tag Y circuit is activated. At this time, the electronic tag sensing unit can receive the tag information sent by the electronic tag Y and determine that the electronic tag Y is in the second state. Therefore, it sends the second feedback information to the control unit. When the control unit receives the second feedback information, it can determine that the clothes hanging on the drying rod assembly and / or the first drying rod is not fully retracted. Therefore, it determines that the drying rod assembly is not in the preset state.

[0089] In this embodiment, for the aforementioned electronic tags x and y, since the types and connections of the switching units in their circuits are different, for electronic tag x, if its tag information is received (at which point the drying rack assembly is determined to be in a preset state), it is determined to be in the first state; otherwise, it is determined to be in the second state. For electronic tag y, if its tag information is not received (at which point the drying rack assembly is determined to be in a preset state), it is determined to be in the first state; otherwise, it is determined to be in the second state.

[0090] In this embodiment, the number of electronic tags can be one or more. When there is one, each first switch and each second switch are connected in series or in parallel and set in the circuit loop of the electronic tag. When there are multiple electronic tags, the connection relationship of the first switch and the second switch in each electronic tag circuit can be the same or different. For example, the first electronic tag circuit includes a first switch and a second switch connected in series, and the first switch is a normally closed switch and the second switch is a normally open switch. The second electronic tag circuit includes other first switches and second switches connected in parallel, and the first switch is a normally open switch and the second switch is a normally closed switch. When both the first electronic tag and the second electronic tag are in the first state, the control unit can determine that the drying rack assembly is in the preset state.

[0091] In this embodiment, the first and second switches can be configured in different electronic tag circuits according to their positional relationship. For example, when there are two electronic tags, the first switch can be divided into two groups, left and right, according to its position in the drying rod assembly. The first switch in the left group can be connected in series or in parallel with the second switch triggered when the first telescopic rod on the left side of the first drying rod is fully retracted and then configured in the circuit of one electronic tag. The first switch in the right group can be connected in series or in parallel with the second switch triggered when the second telescopic rod on the right side of the first drying rod is fully retracted and then configured in the circuit of another electronic tag. Of course, more electronic tags can be configured as needed.

[0092] In this embodiment, when the drying rod assembly includes a retractable first drying rod as described above, a first switch can be installed on the main drying rod and / or the retractable drying rod for hanging clothes. Considering that if a first switch is installed on the retractable drying rod, when the state of the first switch determines that there are no clothes on the retractable drying rod, it cannot be determined that the first drying rod has been retracted. Therefore, the preferred solution in this embodiment is to install a first switch at each hanging position on the main drying rod of the first drying rod.

[0093] In this embodiment, compared to Embodiment 1, the switching unit further includes a second switching unit, which includes a second switch element that can be triggered by the extension / retraction state of the first drying rod. Therefore, when the first drying rod retracts, the second switch element is triggered. Since the opening / closing state of the second switch element can change the state of the electronic tag, the electronic tag sensing unit can determine whether the first drying rod is in a retracted state based on the state of the electronic tag. This serves as one of the criteria for determining the preset conditions of the drying rod assembly or as a basis for the clothes dryer to perform corresponding operations. This avoids the situation where the drying rod collides with the ceiling or suspended ceiling when it rises to the upper limit or storage position because it is not retracted (i.e., the drying rod assembly is not in the preset state), further ensuring the safety of using the clothes dryer.

[0094] Example 3

[0095] This embodiment discloses a drying rod control system. This embodiment adds a third switch unit based on embodiment 1 or embodiment 2. That is, the switch unit also includes a third switch unit. The corresponding drying rod assembly includes a second drying rod that can be retracted or extended. The second drying rod is usually a quilt drying rod. When there is a need to dry quilts or a larger amount of laundry, the second drying rod can be extended to expand the amount of laundry or facilitate the drying of bed sheets, quilts, etc.

[0096] In this embodiment, the third switch unit includes a third switch element disposed on the drying rod assembly and capable of being triggered to change its opening / closing state when the second drying rod is in the retracted state; the third switch unit is disposed in the electronic tag circuit after being connected in series or parallel with the first switch unit and / or the second switch unit. Alternatively, the third switch unit is disposed separately in the electronic tag circuit.

[0097] In this embodiment, the third switch can be disposed on the second drying rod. When the second drying rod is fully retracted, the third switch can contact a certain point on the retracted position of the second drying rod, thereby being triggered. Alternatively, the third switch can be directly disposed at the retracted position of the second drying rod. When the second drying rod is retracted, it will contact the third switch at the retracted position, thereby triggering the third switch. The third switch can also be disposed at other locations on the drying rod assembly; the specific location is not limited, as long as it can be triggered to change the state when the second drying rod is fully retracted. The number of third switches is the same as the number of second drying rods, generally two or more.

[0098] In this embodiment, each third switch can be set in a different electronic tag circuit, or it can be set in the same electronic tag circuit after being connected in series or parallel. Each third switch can also be set in the same electronic tag circuit with the first switch unit and / or the second switch unit, or it can be set in different electronic tag circuits. That is, this embodiment can include one or more electronic tags. When there is one, each third switch is set in the electronic tag circuit after being connected in series or parallel with the first switch unit and / or the second switch unit. When there are multiple, each electronic tag circuit can only set one, two, or all three of the first switch unit, second switch unit, and third switch. Specifically, the switch unit set in each electronic tag circuit can be as follows: only the first switch, second switch, or third switch; simultaneously the first switch and second switch; simultaneously the first switch and third switch; simultaneously the second switch and third switch; and simultaneously the first switch, second switch, and third switch. In each circuit, the number of the corresponding first switch, second switch, and third switch can be one or more.

[0099] In this embodiment, the third switch can be either a normally open switch or a normally closed switch. When the third switch is a normally open switch, it is in a closed state when the first drying rod is fully retracted; otherwise, it is in an open state. When the third switch is a normally closed switch, it is in an open state when the second drying rod is fully retracted; otherwise, it is in a closed state. When the electronic tag circuit includes multiple third switches: if the third switch is a normally open switch, the third switches are connected in series; if the third switch is a normally closed switch, the first switches are connected in parallel.

[0100] In this embodiment, when the electronic tag circuit includes a first switching unit and a third switching unit: if the first switching element is a normally closed switch and the third switching element is a normally open switch, then the first switching unit and the third switching unit are connected in series; if the first switching element is a normally open switch and the third switching element is a normally closed switch, then the first switching unit and the third switching unit are connected in parallel. When the electronic tag circuit includes a first switching unit, a second switching unit, and a third switching unit: if the first switching element is a normally closed switch, the second switching unit is a normally open switch, and the third switching element is a normally open switch, then the first switching unit, the second switching unit, and the third switching unit are connected in series; if the first switching element is a normally open switch, the second switching unit is a normally closed switch, and the third switching element is a normally closed switch, then the first switching unit, the second switching unit, and the third switching unit are connected in parallel.

[0101] In this embodiment, when none of the first switches are triggered and the third switch is triggered, the states of the first and third switches cause the electronic tag to enter a first state; when one or more of the first switches are triggered, and / or the third switch is not triggered, the states of the first and third switches cause the electronic tag to enter a second state. In the above cases, when the same electronic tag circuit includes both first and third switches, the first switch can be selected as a normally closed switch and the third switch as a normally open switch, or the first switch can be selected as a normally open switch and the third switch as a normally closed switch.

[0102] Based on the settings of the switch unit described above in this embodiment, the preset state of the drying rod assembly can be set as follows: the drying rod assembly is in an un-clothed state and the second drying rod is in a retracted state; specifically:

[0103] When the first switching element is a normally closed switch and the third switching element is a normally open switch, then in the S-circuit of the electronic tag circuit, as follows: Figure 4aAs shown, each first switch and each third switch are connected in series in the circuit. Based on this, when no clothes are hung at any of the hanging positions of the drying rod assembly and the second drying rod is fully retracted, the electronic tag S circuit is turned on. At this time, the electronic tag sensing unit can receive the tag information sent by the electronic tag S, determine that the electronic tag S is in the first state, and therefore send the first feedback information to the control unit. When the control unit receives the first feedback information, it can determine that no clothes are hung at any of the hanging positions of the drying rod assembly and the second drying rod is fully retracted, and therefore determines that the drying rod assembly is in the preset state. When clothes are hung at one or more of the hanging positions, the first switch at the corresponding hanging position is turned off. When the second drying rod is not fully retracted, the corresponding third switch is turned off. Therefore, in the above cases, the electronic tag S circuit is not turned on. At this time, the electronic tag sensing unit cannot receive the tag information sent by the electronic tag S, determine that the electronic tag S is in the second state, and therefore send the second feedback information to the control unit. When the control unit receives the second feedback information, it can determine that the clothes hanging on the drying rod assembly and / or the second drying rod are not fully retracted, and therefore determines that the drying rod assembly is not in the preset state.

[0104] When the first switching element is a normally open switch and the third switching element is a normally closed switch, then in the electronic tag t circuit, if... Figure 4b As shown, each first switch and each third switch are connected in parallel in the circuit. Based on this, when no clothes are hung at any of the hanging positions on the drying rack assembly and the second drying rack is fully retracted, the electronic tag t circuit is not connected. In this case, the electronic tag sensing unit cannot receive the tag information sent by the electronic tag t, determining that the electronic tag t is in the first state. Therefore, it sends first feedback information to the control unit. Upon receiving the first feedback information, the control unit can determine that no clothes are hung at any of the hanging positions on the drying rack assembly and the second drying rack is fully retracted, thus determining that the drying rack assembly is in the preset state. However, when clothes are hung at one or more of the hanging positions, the first switch at the corresponding hanging position closes. When the second drying rack is not fully retracted, the corresponding third switch closes. In this case, the electronic tag t circuit is connected. At this time, the electronic tag sensing unit can receive the tag information sent by the electronic tag t, determining that the electronic tag t is in the second state. Therefore, it sends second feedback information to the control unit. Upon receiving the second feedback information, the control unit can determine that the clothes hanging on the drying rack assembly and / or the second drying rack is not fully retracted, thus determining that the drying rack assembly is not in the preset state.

[0105] In this embodiment, for the aforementioned electronic tags s and t, since the types and connections of the switching units in their circuits are different, for electronic tag s, if its tag information is received (at which time the drying rack assembly is in a preset state), it is determined to be in the first state; otherwise, it is determined to be in the second state. For electronic tag t, if its tag information is not received (at which time the drying rack assembly is in a preset state), it is determined to be in the first state; otherwise, it is determined to be in the second state.

[0106] In this embodiment, it can also be configured such that when the first switch is not triggered, the second switch is triggered, and the third switch is triggered in each electronic tag circuit, the state of the first and second switches causes the electronic tag to enter a first state; when at least one of the following conditions is met: one or more of the first switches are triggered, the second switch is not triggered, and the third switch is not triggered, the state of the first, second, and third switches causes the electronic tag to enter a second state. Based on the above-mentioned switch unit settings, the preset state of the drying rod assembly in this embodiment can be set as follows: the drying rod assembly is in an un-clothed state, the first drying rod is in a retracted state, and the second drying rod is in a folded-up state. When the same electronic tag circuit includes the first, second, and third switches simultaneously, the first switch can be selected as a normally closed switch, and the second and third switches can be selected as normally open switches, or the first switch can be selected as a normally open switch, and the second and third switches can be selected as normally closed switches. Specifically:

[0107] When the first switching element is a normally closed switch, and the second and third switching elements are normally open switches, then in the electronic tag p circuit, as follows: Figure 5aAs shown, each of the first, second, and third switches is connected in series in the circuit. Based on this, when no clothes are hanging at any of the hanging positions on the drying rack assembly, the first drying rack is fully retracted, and the second drying rack is fully retracted, the electronic tag p circuit is activated. At this time, the electronic tag sensing unit can receive the tag information sent by the electronic tag p, determining that the electronic tag p is in the first state. Therefore, it sends first feedback information to the control unit. Upon receiving the first feedback information, the control unit can determine that no clothes are hanging at any of the hanging positions on the drying rack assembly, the first drying rack is fully retracted, and the second drying rack is fully retracted, thus determining that the drying rack assembly is in the preset state. When clothes are hung at one or more of the hanging positions, the first switch at the corresponding hanging position... When either the first telescopic rod or the second telescopic rod of the first drying rack is not fully retracted, the corresponding second switch is disconnected. When the second drying rod is not fully retracted, the corresponding third switch is disconnected. Therefore, in the above situations, the electronic tag p circuit is not conductive. At this time, the electronic tag sensing unit cannot receive the tag information sent by the electronic tag p, and determines that the electronic tag is in the second state. Therefore, it sends the second feedback information to the control unit. When the control unit receives the second feedback information, it can determine that at least one of the following situations exists: clothes are hanging on the drying rack assembly, the first drying rod is not fully retracted, or the second drying rod is not fully retracted. Therefore, it determines that the drying rack assembly is not in the preset state.

[0108] When the first switching element is a normally open switch and the second and third switching elements are normally closed switches, then in the electronic tag q circuit, if... Figure 5bAs shown, each of the first, second, and third switches is connected in parallel in the circuit. Based on this, when no clothes are hanging at any of the hanging positions on the drying rack assembly, the first drying rack is fully retracted, and the second drying rack is fully retracted, the electronic tag q circuit is not conductive. At this time, the electronic tag sensing unit cannot receive the tag information sent by the electronic tag, determining that the electronic tag q is in the first state. Therefore, it sends first feedback information to the control unit. Upon receiving the first feedback information, the control unit can determine that no clothes are hanging at any of the hanging positions on the drying rack assembly, the first drying rack is fully retracted, and the second drying rack is fully retracted, thus determining that the drying rack assembly is in the preset state. When clothes are hung on one or more of the hanging positions, the first switch at the corresponding hanging position closes. When one of the first telescopic rods or the second telescopic rod is not fully retracted, the corresponding second switch closes. When the second rod is not fully retracted, the corresponding third switch closes. Under these circumstances, the electronic tag q-loop is activated. At this time, the electronic tag sensing unit can receive the tag information sent by the electronic tag and determine that the electronic tag is in the second state. Therefore, it sends the second feedback information to the control unit. When the control unit receives the second feedback information, it can determine that at least one of the following situations exists: clothes are hanging on the drying rod assembly, the first drying rod is not fully retracted, or the second drying rod is fully authorized. Therefore, it determines that the drying rod assembly is not in the preset state.

[0109] In this embodiment, for the aforementioned electronic tags p and q, since the types and connections of the switching units in their circuits are different, for electronic tag q, if its tag information is received (at which time the drying rack assembly is in a preset state), it is determined to be in the first state; otherwise, it is determined to be in the second state. For electronic tag q, if its tag information is not received (at which time the drying rack assembly is in a preset state), it is determined to be in the first state; otherwise, it is determined to be in the second state.

[0110] In this embodiment, the number of electronic tags can be one or more. When there is one, each first switch, each second switch, and each third switch are connected in series or in parallel and set in the circuit loop of the electronic tag. When there are multiple, they can be set in different electronic tag loops according to the positional relationship of the first switch, the second switch, and the third switch. For example, when the system of this embodiment includes two electronic tags, the first switch can be divided into left and right groups according to its position in the drying rod assembly. The first switch of the left group can be connected in series or parallel with the second switch triggered when the first telescopic rod on the left side of the first drying rod is fully retracted and the third switch triggered when one of the second drying rods is fully retracted on the left side of the drying rod assembly, and then set in the circuit loop of one electronic tag. The first switch of the right group can be connected in series or parallel with the second switch triggered when the second telescopic rod on the right side of the first drying rod is fully retracted and the third switch triggered when the other second drying rod is fully retracted on the right side of the drying rod assembly, and then set in the circuit loop of another electronic tag. Of course, more electronic tags can be set as needed, and the corresponding first switch, second switch and third switch can be set in the corresponding electronic tag circuit loop based on the positional relationship or other relationship between each first switch, each second switch, each third switch and each electronic tag.

[0111] In this embodiment, when multiple electronic tags are included, the state of the electronic tags under the following conditions is determined based on the type (normally open or normally closed) and connection relationship (series or parallel) of the first, second and / or third switches in each electronic tag circuit: "no clothes are hung at the corresponding position of the drying rod assembly, the telescopic rod corresponding to the first drying rod is fully retracted, and the second drying rod is fully retracted." Based on this, the control unit can ultimately determine the state of the drying rod assembly according to the state of each electronic tag (which can be known from the corresponding feedback information).

[0112] For example, when there are two electronic tags, the first electronic tag circuit includes a first switch, a second switch, and a third switch connected in series, with the first switch being a normally closed switch and the second and third switches being normally open switches; the second electronic tag circuit includes a first switch, a second switch, and a third switch connected in parallel, with the first switch being a normally open switch and the second and third switches being normally closed switches. When the first electronic tag is in the first state (corresponding to the first electronic tag circuit where: no clothes are hung at the clothes-hanging positions of the first switches, the first drying rods corresponding to the second switches are fully retracted, and the second drying rods corresponding to the third switches are fully retracted), and the second electronic tag is in the second state (corresponding to the second electronic tag circuit where: no clothes are hung at the clothes-hanging positions of the second switches, the first drying rods corresponding to the second switches are fully retracted, and the second drying rods corresponding to the third switches are fully retracted), the control unit can determine that the drying rod assembly is in the preset state.

[0113] In this embodiment, compared to Embodiment 1, the switch unit further includes a third switch unit. The third switch unit is connected in series or parallel with the first and second switch units and is set in the electronic tag circuit. The third switch unit includes a third switch element that is set on the drying rod assembly and can be triggered to change the opening and closing state when the second drying rod is in the retracted state. Based on this, when the second drying rod is in the retracted position, the third switch element can be triggered. Since the opening and closing of the third switch element can change the state of the electronic tag, the electronic tag sensing unit can confirm whether the third drying rod is in the retracted state based on the state of the electronic tag. This can prevent the clothes drying rack and quilt drying rod from colliding with the ceiling or suspended ceiling due to not being retracted, and further ensure the safety of using the clothes drying rack.

[0114] In this embodiment, the first, second, and third switches can all be normally closed or normally open switches. When the first switch is normally closed and the second and third switches are normally open, the electronic tag sensing unit determines that the electronic tag is in the first state only when it receives tag information. This setting can improve the detection accuracy. Compared with the situation where the electronic sensing unit determines that the electronic tag is in the first state when it does not receive tag information (that is, when the first to third switches are not of the above types), it can avoid the situation where the electronic tag is not conducting due to other uncontrollable situations, resulting in the false judgment that the drying rack assembly meets the preset state.

[0115] Example 4

[0116] This embodiment also discloses a clothes drying rack, including a main unit, a drying rod assembly, a power system, and a drying control system as described in any one of embodiments 1 to 3. Wherein:

[0117] The main unit of the clothes drying rack is fixed in the installation environment, such as on the ceiling of a balcony. The main unit includes a main controller, a drying module, and a lighting module. The drying rod assembly is used for drying clothes and is located below the main unit via a power system that allows it to move up and down. The power system of the clothes drying rack can include a motor, a reel, a pulley assembly, and a steel wire rope. The main controller is connected to the motor via a motor driver to control the motor's rotation. The reel is driven by the motor's output shaft. One end of the steel wire rope is mounted on the reel, and the other end passes through a pulley in the pulley assembly to change direction (from horizontal to vertical) and is fixedly connected to the drying rod assembly below the main unit. The reel rotates under the motor's power to wind up and unwind the steel wire rope, thereby causing the drying rod assembly on the steel wire rope to move up or down. Additionally, the main controller can connect to functional modules such as the drying module, lighting module, and disinfection module to control their operating status.

[0118] The above description is only an optional implementation method for some implementation scenarios of this application. It should be noted that for those skilled in the art, other similar implementation methods based on the technical concept of this application without departing from the technical concept of this application also fall within the protection scope of the embodiments of this application.
