Detailed Implementation

[0042] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0043] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0044] Currently, electric clothes drying racks typically use a drive unit connected to a steel wire rope to raise and lower the drying rack. A folding frame connects the main unit to the drying rack to prevent it from swaying. Since the folding frame and steel wire rope are moving components, ensuring the drying rack is continuously powered, especially by the main unit, remains a major challenge for technicians in the industry. This presents a challenge to implementing various functions and monitoring / control features on the drying rack. Existing technologies have addressed some functional requirements of the drying rack through contact power supply, cable reel power supply, and wireless battery charging, but these methods also have drawbacks, such as limitations on cost, electrical safety, and structural integrity. For example, in contact power supply, the power supply structure is only activated when the drying rack rises to contact the main unit, allowing the electrical devices on the rack to operate. If the devices need to continue operating after the rack descends, energy storage devices such as battery capacitors are required, which undoubtedly increases costs, and the frequent switching of the power supply structure poses a safety hazard. Therefore, this invention bypasses the industry's conventional understanding that the drying rack needs to be powered and makes the following innovations.

[0045] Reference Figures 1 to 11 A preferred embodiment of the drying rack described in this utility model includes:

[0046] Drying rod assembly 10;

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

[0048] An electronic tag 30 is mounted on the drying rod assembly and electrically connected to the detection unit 20. It is suitable for cooperating with the sensing unit 40 of the clothes drying rack main unit 100, generating different states based on the detection unit 20. This invention creatively bypasses the industry's conventional understanding that drying racks require electricity by combining a detection unit and an electronic tag on the drying rod assembly. It achieves the required functional detection and control effectively without electricity, and the overall structure is well-integrated.

[0049] Specifically, the detection unit of this 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 a power supply. When the micro switch unit is closed, the electronic tag forms an internal circuit, allowing it to detect a corresponding signal when it approaches the sensing unit. Conversely, when the micro switch unit is open, the electronic tag cannot form an internal circuit, and therefore, it cannot detect a corresponding signal when it approaches the sensing unit. Thus, the micro switch unit can act as a detection end to detect different states of the drying rack assembly, such as whether clothes are hung on the rack, whether the rack encounters resistance when rising, whether the telescopic rod is retracted, and whether the blanket rod is retracted. Based on the detected different states of the drying rack assembly, the host can employ different control logics to achieve different functions. The sensing unit 40 is located on the host 100, specifically on the end cover 101.

[0050] Furthermore, the detection unit is provided in multiple locations. The drying rod assembly 10 includes two parallel first drying rods 11 and a bracket 12 connecting 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 to prioritize the detection of the status of the clothes drying rod. In the daily use scenario of electric clothes drying racks, the drying rod is the most frequently used. If the clothes are hung on the drying rod and the height is raised to the upper limit according to conventional control, it is easy to damage the clothes hanger, main unit, or ceiling. Therefore, this detection is the basic guarantee for realizing the hanging or rising obstacle detection function.

[0051] The first drying rod 11 is provided with at least one movable hanging part 111, which is adapted to cooperate with the detection unit 20.

[0052] Furthermore, multiple movable hanging parts 111 are provided, each movable in the vertical direction of the first drying rod 11. Each movable hanging part is adapted to a detection unit 20, which is used to detect the vertical movement state of the movable hanging part. Specifically, multiple movable hanging parts 11 are arranged along the length of the first drying rod 11. They can be located above or below the first drying rod. In this embodiment, multiple movable hanging parts 111 are movably connected to the upper end of the first drying rod 11 and are linked with a micro switch unit to realize the clothes hanging detection of the clothes rod. Setting the movable hanging parts above the first drying rod can also realize the upward obstruction detection of the 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 part 111 is provided with a locking part 114 that fits into the first slot 113. The locking part 114 is engaged within the first slot 113 and can rotate relative to the first slot 113. See details. Figure 7 The first slot 113 has a circular cross-section and an opening for the engaging part 114 to pass through. This design facilitates the installation of movable hangers, which can be easily slid into the first slot one by one. The first slot 113 is located on both sides of the center line of the upper end face of the first drying rod 11, taking into account both the versatility of parts and ease of installation. The engaging part 114 is located on one side of the movable hanger 111, allowing the movable hanger a certain vertical movement space on the first drying rod. At the same time, the movable hanger 111 also has a limiting part 115, which is located outside the engaging part 114, to limit the rotation range of the movable hanger in the first slot and prevent it from deflecting outwards from the first drying rod. The limiting part 115 is set close to the upper end face of the first drying rod when the movable hanger does not trigger the micro switch unit, thereby improving the overall structural integrity of the drying rod.

[0054] Furthermore, the first drying rod 11 is also 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 to the movable hanging part 11. For details, see... Figure 7 The second slot 116 is formed in the middle of the upper end face of the first drying rod 11, and the detection unit 20 is inserted therein. The detection unit 20 located therein has an elastic trigger part. The maximum stroke of the elastic trigger part is greater than its pre-detection stroke. That is, after the movable hanging part is installed, the elastic trigger part does not have its maximum stroke, but gives the movable hanging part an initial elastic force to enhance the structural stability of each movable hanging part.

[0055] Furthermore, the movable hanging parts are provided in multiple configurations and can be separated and brought together along the first drying rod. A detection unit is used to detect the separation or gathering of the movable hanging parts. Specifically, this embodiment is not shown in the accompanying drawings. In some existing electric clothes drying racks, the movable hanging parts can be separated or brought together, which usually requires a locking mechanism to fix their position. However, if the locking mechanism malfunctions, the clothes hanging on the movable hanging parts are easily blown together by the wind, which is not conducive to drying. In this case, detecting the separation of the movable hanging parts helps to notify and troubleshoot the fault. The detection unit can be located at the locking mechanism.

[0056] Furthermore, the first drying rod 11 is movably connected to two ends by a first drying rod telescopic rod 112, wherein one of the aforementioned detection units 20 is used to detect the activity state of the first drying rod telescopic rod. Specifically, this detection unit mainly detects whether the telescopic rod has retracted to the first drying rod. As mentioned earlier, in an installation environment with a suspended ceiling, the extended telescopic rod of an electric clothes drying rack generally extends beyond the installation groove. If the telescopic rod is not retracted when the drying rack is raised, it is easy to collide and damage the suspended ceiling or the drying rack. The detection unit can be set on the first drying rod, corresponding to the retraction distance of the telescopic rod, or it can be set on other components connected to it, such as a bracket.

[0057] Furthermore, a fixing rod 14 is connected to the end of the first telescopic drying rod 112. The fixing rod 14 abuts against the bracket 12 when the first telescopic drying rod 112 is fully retracted to the first drying rod 11. The detection unit 20 is placed on the fixing rod 14 or the bracket 12 and is provided with a detection part 21 for detecting the contact between the two. Specifically, in this embodiment, see... Figure 4 and 5 The detection unit is mounted on the bracket 12. When the telescopic rod retracts, the fixing rod 14 is in close contact with or abuts against the bracket 12. Therefore, the detection unit mainly detects whether the telescopic rod has retracted indirectly by detecting whether the fixing rod abuts against the bracket. Mounting the unit on the bracket 12 also facilitates the placement of electrical components and centralized wiring, reducing structural complexity.

[0058] Furthermore, the bracket 12 is provided with a bottom shell 121, on which a mounting base 122 for fixing the detection unit 20 is provided. The detection part 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, wherein the detection part 21 is rotatably connected to the bottom shell 122, one side of its movable end abuts against 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 against the fixing rod. When the telescopic rod is retracted, the fixing rod 14 abuts against the detection part 21 until the micro switch is triggered. This design can better improve the ease of assembly.

[0059] Furthermore, a movable rod is movably connected to the fixed rod 14, and a second drying rod 13 is connected to the end of the movable rod. The second drying rod can be unfolded and retracted relative to the first drying rod. A detection unit is used to detect the unfolded or retracted state of the second drying rod. Specifically, the second drying rod is a quilt drying rod. In this embodiment, the second drying rod 13 can be unfolded parallel to the first drying rod 11, and the movable rod can extend and retract within the fixed rod 14 (not shown in the figure). This detection unit is mainly used to detect whether the second drying rod is retracted. As mentioned earlier, in an installation environment with a suspended ceiling, the unfolded quilt drying rod of an electric clothes drying rack generally extends beyond the installation groove. If the quilt drying rod is not retracted when the drying rack is raised, it is easy to collide and damage the suspended ceiling or the drying rack. This detection unit is also a micro-switch unit, and its position can be inside the fixed rod, at the fully retracted position of the movable rod.

[0060] The multiple detection units are connected in series or in parallel simultaneously, and their initial signal states are identical. For details, see [link to documentation]. Figure 10a Each detection unit is a micro switch unit. Each first switch, each second switch, and each third switch are respectively used to detect each movable hanging part, each first drying rod telescopic rod, and each second drying rod (for detecting the first drying rod telescopic rod, in addition to the switches at the two brackets mentioned above, an additional switch can be added to assist in the detection to improve accuracy; the same applies when detecting the second drying rod). Each switch is set in series in the circuit. Based on this, when none of the movable parts of the first drying rack are hung with clothes, the first drying rack telescopic rod is fully retracted, and the second drying rack is fully closed, the electronic tag circuit is activated. At this time, the sensing unit can receive the tag information sent by the electronic tag, confirming that the electronic tag is in the first state. Upon receiving the corresponding signal, the main control unit can determine that none of the movable parts of the first drying rack are hung with clothes, the first drying rack telescopic rod is fully retracted, and the second drying rack is fully closed. Therefore, when the drying rack rises, it can continue to rise to the upper limit without triggering an alarm or shutdown logic. Conversely, 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 main control unit can trigger an alarm or shutdown logic according to preset logic. (See also...) Figure 10bEach of the first, second, and third switches is connected in parallel in the circuit. Based on this, when no clothes are hung on any of the movable parts of the first drying rack, the first drying rack telescopic rod is fully retracted, and the second drying rack is fully closed, the electronic tag circuit is disconnected. At this time, the sensing unit cannot receive the tag information, and the main control unit can determine that no clothes are hung on any of the movable parts of the first drying rack, the first drying rack telescopic rod is fully retracted, and the second drying rack is fully closed. Therefore, when the drying rack rises, it can continue to rise to the upper limit without triggering the alarm or shutdown logic. Conversely, if any state is not met, the electronic tag circuit is turned on. At this time, the sensing unit can receive the tag information, and the main control unit can trigger the alarm or shutdown logic according to the preset logic.

[0061] Furthermore, the electronic tag 30 has multiple sub-tags, each of which is connected to one or a group of detection units to obtain the activity status of the detected part in the drying rack assembly. See details... Figure 11 In this embodiment, multiple sub-tags work independently to generate different detection signals. For example, one sub-tag can be connected to the detection unit on the clothesline. When clothes are detected, it sends a signal separately for the sensing unit to recognize. At this time, the host control unit obtains the corresponding status signal.

[0062] The electric clothes drying rack described in this utility model includes the aforementioned drying rack. By adopting the aforementioned drying rack, the electrical safety problem is overcome, the level of intelligent control is greatly improved, the overall structural integrity is taken into account, and it also has a significant cost advantage, making it easy to be transformed and applied on a large scale.

[0063] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
