DETAILED DESCRIPTION

[0042] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

[0043] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0044] Currently, electric clothes dryers generally use a drive device connected to a steel wire rope to drive the drying rack up and down. A folding frame is connected between the main unit and the drying rack to prevent the drying rack from swinging. Since the folding frame and the steel wire rope are moving components, the power supply of the existing electric clothes dryers, especially the continuous power supply from the main unit, remains a major problem that troubles technicians in the industry. This poses certain challenges to implementing various functions or detection and control on the drying rack. In the existing technology, contact power supply, reel power supply, and battery wireless charging have emerged to solve some of the functional requirements of the drying rack. However, there are also certain disadvantages, such as cost, power safety, and structural integrity. For example, in the contact power supply method, the power supply structure is only connected when the drying rack is raised to contact with the main unit. At this time, the power-consuming devices on the drying rack can only work. If the power-consuming devices need to continue to work after the drying rack is lowered, an energy storage device such as a battery capacitor is required. This undoubtedly increases costs and the power supply structure has certain hidden dangers due to frequent short circuits. Based on this, the present invention circumvents the inherent industry perception that the drying rack needs to be powered and makes the following innovations.

[0045] Reference Figures 1 to 11 The preferred embodiment of the drying rack of the present invention comprises:

[0046] Drying rod assembly 10;

[0047] The detection unit 20 is provided on the drying rod assembly;

[0048] The electronic tag 30 is mounted on the clothes drying rod assembly and electrically connected to the detection unit 20. It is adapted to cooperate with the sensing unit 40 of the clothes drying machine main unit 100 to generate different states based on the detection unit 20. By creatively combining the detection unit and the electronic tag on the clothes drying rod assembly, the present invention circumvents the inherent industry perception that clothes drying racks require electrical power. This allows for the required functional detection and control without requiring electrical power, resulting in a more integrated structure.

[0049] Specifically, the detection unit described in the present invention is preferably a micro switch unit, and the electronic tag is preferably an RFID (Radio Frequency Identification) passive tag. The electrical connection between the two only requires a wire and does not require power supply. The closing of the micro switch unit causes the electronic tag to form an internal loop. At this time, the electronic tag can detect the corresponding signal when it is close to the sensing unit, while the disconnection of the micro switch unit prevents the electronic tag from forming an internal loop. At this time, the electronic tag cannot detect the corresponding signal when it is close to the sensing unit. In this way, the micro switch unit can be used as a detection end to detect different states of the clothes drying rod assembly, such as whether the clothes drying rod is hung with clothes, whether the clothes drying rod encounters resistance when rising, whether the telescopic rod is retracted, whether the rod is retracted, etc. Based on the different states of the clothes drying rod assembly detected, the host can use different control logic to achieve different functions. The sensing unit 40 is provided on the host 100, and the specific setting position can be on the end cover 101.

[0050] Furthermore, the detection unit is provided in plurality. The drying rod assembly 10 includes two first drying rods 11 arranged in parallel and a bracket 12 connected between the two first drying rods 11. At least one detection unit 20 is provided on the first drying rod 11. Specifically, the first drying rod 11 is a clothes drying rod, and at least one micro switch unit is provided on the first drying rod 11 in order to prioritize the status detection of the clothes drying rod. In the daily use scenario of electric clothes drying machines, the most frequently used drying rod is the clothes drying rod. When users hang clothes on the clothes drying rod, if the rod is raised to the upper limit according to conventional control, it is easy to damage the hanger, the main unit or the ceiling. Therefore, this detection is the basic guarantee for realizing the function of hanging clothes or rising in the event of resistance.

[0051] At least one movable hanging part 111 is provided on the first drying rod 11 , and the movable hanging part 111 is suitable for cooperating with the detection unit 20 .

[0052] Furthermore, the movable hangers 111 are provided in plurality and are movable in the vertical direction of the first clothes-drying rod 11. Each movable hanger is adapted to a detection unit 20, and the detection unit 20 is used to detect the vertical movable state of the movable hanger. Specifically, the plurality of movable hangers 11 are arranged along the length direction of the first clothes-drying rod 11. They can be arranged above the first clothes-drying rod or below the first clothes-drying rod. In this embodiment, the plurality of movable hangers 111 are movably connected to the upper end of the first clothes-drying rod 11 and are linked with a micro-switch unit to realize the detection of clothes hanging on the clothes-drying rod. The movable hangers are arranged above the first clothes-drying rod and can also realize the detection of resistance to the rise of the clothes-drying rack at the same time. The structure is simple and the cost is low.

[0053] Furthermore, the first drying rod 11 is provided with a first slot 113 along its length, and the movable hanging member 111 is provided with a locking portion 114 adapted to the first slot 113, and the locking portion 114 is locked in the first slot 113 and can rotate relative to the first slot 113. Figure 7 The first slot 113 has a circular cross-section and is provided with an opening for the locking portion 114 to pass through. This design can facilitate the installation of the movable hanger, and it only needs to be slid into the first slot one by one. The first slot 113 is set on the upper end surface of the first drying rod 11 on both sides of the end surface center line, taking into account the versatility of parts and the convenience of installation. The locking portion 114 is located on one side of the movable hanger 111, so that the movable hanger can have a certain upward and downward movement space on the first drying rod. At the same time, the movable hanger 111 is also provided with a limiting portion 115, which is located on the outside of the locking portion 114 to limit the rotation range of the movable hanger in the first slot and prevent it from deflecting to the outside of the first drying rod. The limiting portion 115 is set close to the upper end surface of the first drying rod when the movable hanger does not trigger the microswitch unit to enhance the integrity of the entire drying rod structure.

[0054] Furthermore, the first drying rod 11 is provided with a second slot 116 along its length, and the detection unit 20 is engaged in the second slot 116 and provides an upward elastic force for the movable hanging part 11. Figure 7 The second slot 116 is formed in the middle of the upper end surface of the first drying rod 11, and the detection unit 20 is inserted therein. The detection unit 20 provided therein has an elastic trigger part, and the maximum stroke of the elastic trigger part is greater than its pre-detection stroke, that is, after the movable hanger is installed, the elastic trigger part is not its maximum stroke but gives the movable hanger an initial elastic force, thereby enhancing the structural stability of each movable hanger.

[0055] Furthermore, the movable hangers are provided in plurality and can be separated and gathered along the first clothes-drying rod, wherein a detection unit is used to detect the separation or gathering of the movable hangers. Specifically, although this embodiment is not shown in the accompanying drawings, the movable hangers of some existing electric clothes-drying machines can be separated or gathered, and they are usually fixed in position by a locking mechanism. If the locking mechanism fails, the clothes hung on the movable hangers are easily blown by the wind and gathered, which is not conducive to drying. In this case, detecting the separation of the movable hangers can help to notify and troubleshoot the fault. The detection unit can be located at the locking mechanism.

[0056] Furthermore, first airing rods 112 are movably connected at both ends of the first airing rod 11, and a detection unit 20 is used to detect the movable state of the first airing rod's telescopic rod. Specifically, the detection unit primarily detects whether the telescopic rod has been retracted to the first airing rod. As previously mentioned, when an electric clothes dryer is installed in an environment with a suspended ceiling, the extended telescopic rod generally extends beyond the mounting slot. If the telescopic rod is not retracted during the rise of the clothes drying rack, it is prone to collision and damage to the suspended ceiling or clothes drying rack. The detection unit can be located on the first airing rod, corresponding to the retraction distance of the telescopic rod, or it can be located on another component connected to it, such as a bracket.

[0057] Furthermore, the end of the first air-drying rod telescopic rod 112 is connected to a fixed rod 14, and the fixed rod 14 abuts against the bracket 12 when the first air-drying rod telescopic rod 112 is fully retracted to the first air-drying rod 11. The detection unit 20 is placed on the fixed rod 14 or the bracket 12 and is provided with a detection portion 21 for detecting the abutment between the two. Specifically, in this embodiment, see Figure 4 and 5 The detection unit is mounted on bracket 12. When the telescopic rod is retracted, the fixed rod 14 abuts against or contacts bracket 12. Therefore, the detection unit indirectly detects whether the telescopic rod has been retracted by detecting whether the fixed rod contacts the bracket. Positioning the detection unit on bracket 12 facilitates the layout of electrical components and centralized wiring, reducing structural complexity.

[0058] Furthermore, the bracket 12 is provided with a bottom shell 121, and a mounting seat 122 for fixing the detection unit 20 is provided on the bottom shell 121. The detection portion 21 protrudes from the side wall of the bottom shell 122 and can abut against the fixing rod 14. Specifically, in this embodiment, see Figure 4 and 5 The detection unit here is a micro switch structure, in which the detection part 21 is rotatably connected to the bottom shell 122, one side of its movable end abuts the micro switch spring, and the other side of its movable end protrudes from the side wall of the bottom shell 122 (not shown in the figure) to abut the fixing rod. When the telescopic rod is retracted, the fixing rod 14 abuts the detection part 21 until the micro switch is triggered. This design can better improve the convenience of assembly.

[0059] Furthermore, a movable rod is movably connected to the fixed rod 14, and the end of the movable rod is connected to a second airing rod 13. The second airing rod can be expanded and retracted relative to the first airing rod, and a detection unit is used to detect the expanded or retracted state of the second airing rod. Specifically, the second airing rod is a quilt airing rod. In this embodiment, the second airing rod 13 can be expanded parallel to the first airing rod 11, and the movable rod can be movably extended and retracted within the fixed rod 14 (not shown). The detection unit is mainly used to detect whether the second airing rod is retracted. As mentioned above, when an electric clothes drying machine is installed in an environment with a suspended ceiling, the expanded airing rod generally extends beyond the installation slot. When the clothes drying rack is raised, if the airing rod is not retracted, it is also easy to collide and damage the suspended ceiling or clothes drying rack. The detection unit is also a micro switch unit, which can be located within the fixed rod, at the fully retracted position of the movable rod.

[0060] The multiple detection units are connected in series or in parallel at the same time, and the initial signal states are the same. Figure 10a Each detection unit is a micro switch unit, and each first switch component, each second switch component and each third switch component respectively detects each movable hanger, each first telescopic rod and each second rod (in addition to the switches at the above two brackets for detecting the telescopic rod of the first rod, an additional switch can be added to assist in detection to improve accuracy, and the same applies to detecting the second rod). Each switch is set to a series relationship in the circuit. Based on this, when no clothes are hung on the movable hangers of the first drying rod, the telescopic rod of the first drying rod is in a fully retracted state, and the second drying rod is in a fully folded state, the electronic tag circuit is connected. At this time, the sensing unit can receive the tag information sent by the electronic tag and determine that the electronic tag is in the first state. When the host main control unit receives the corresponding signal, it can determine that no clothes are hung on the movable hangers of the first drying rod, the telescopic rod of the first drying rod is in a fully retracted state, and the second drying rod is in a fully folded state. Then, when the drying rack rises, it can continue to rise to the upper limit without triggering the alarm or shutdown logic. On the contrary, if any state is not met, the electronic tag circuit is disconnected. At this time, the sensing unit cannot receive the tag information, and the host main control unit can trigger the alarm or shutdown logic according to the preset logic. Figure 10b, each first switch component, each second switch component and each third switch component are set in a parallel relationship in the circuit. Based on this, when no clothes are hung on the movable hangers of the first clothes drying rod, the telescopic rod of the first clothes drying rod is in a fully retracted state and the second clothes drying rod is in a fully retracted state, the electronic tag circuit is disconnected. At this time, the sensing unit cannot receive the tag information. The host main control unit can determine that no clothes are hung on the movable hangers of the first clothes drying rod, the telescopic rod of the first clothes drying rod is in a fully retracted state and the second clothes drying rod is in a fully retracted state, and then when the clothes drying rack rises, it can continue to rise to the upper limit without triggering the alarm or shutdown logic; on the contrary, if any state is not met, the electronic tag circuit is connected, at this time the sensing unit can receive the tag information, and the host main control unit can trigger the alarm or shutdown logic according to the preset logic.

[0061] Furthermore, the electronic tag 30 is provided with a plurality of sub-tags, and the plurality of sub-tags are respectively connected to one or a group of detection units to obtain the activity status of the detected part of the drying rod assembly. Figure 11 In this embodiment, multiple sub-tags work independently to generate different detection signals. For example, one of the sub-tags can be connected to the detection unit on the clothesline separately. When it detects hanging clothes, it sends a signal separately for the sensing unit to identify. At this time, the host main control unit obtains the corresponding status signal.

[0062] The electric clothes drying machine described in the present invention includes the above-mentioned drying rack. By adopting the above-mentioned drying rack, the problem of electrical safety is overcome, the level of intelligent control is greatly improved, and the structural integrity is taken into account. It also has a great advantage in cost and is convenient for large-scale transformation and application.

[0063] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
