Description

Technical Field

[0001] This application relates to the technical field of household products, and more particularly to a clothes drying rack with anti-collision function. Background Technology

[0002] In the current smart home field, clothes drying racks, as common household appliances, have attracted much attention regarding their safety and stability. Currently, most existing clothes drying racks on the market use the motor current to determine if the drying rod is stuck. However, this traditional detection method has significant drawbacks.

[0003] On the one hand, the motor current is easily affected by various factors during actual operation, leading to unstable values. For example, fluctuations in power supply voltage, minor changes in the motor's own performance, and electromagnetic interference from other components inside the clothes dryer can all cause abnormal fluctuations in the motor current. This unstable current signal can easily trigger false triggers, causing the clothes dryer to suddenly stop or perform erroneous actions during normal operation, causing great inconvenience to users and potentially affecting the lifespan of the clothes dryer.

[0004] On the other hand, this current-detection-based obstacle detection mechanism requires a significant current value to determine whether the clothesline is obstructed or has hit the ceiling. This means the clothesline must experience considerable resistance for the obstacle detection protection function to be triggered. In reality, even minor resistance can cause slight jamming or deviation from the normal operating trajectory, but because this cannot be detected in time, the problem may worsen or even pose a safety hazard.

[0043] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the operations (or steps) as sequential processes, many of these operations can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but it may also have additional steps not included in the figures. The process may correspond to a method, function, procedure, subroutine, subroutine, etc.

[0047] Unless otherwise stated or defined, the term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0048] For ease of description, the up and down directions mentioned below are... Figure 1 Its vertical direction is consistent with the horizontal direction mentioned below. Figure 1 Its left and right directions are consistent.

[0049] like Figures 1 to 5 As shown, this embodiment provides a clothes drying rack with anti-collision function, including a main unit, a pulley assembly 2, an elastic element 3, a drying rod, and a detection unit 4. The main unit is used to install in a suspended ceiling location such as a ceiling. The drying rod can rise and fall relative to the main unit.

[0050] The main unit includes a control unit, a driver that communicates with the control unit, and a cable.

[0051] The pulley assembly 2 is used to guide the cable. The pulley assembly 2 is slidably mounted on the main unit and can slide relative to the main unit. The sliding of the pulley assembly 2 can be vertical, downward tilting, or horizontal. The embodiments of this application are described using vertical sliding as an example.

[0052] One end of the elastic element 3 is connected to the main unit, and the other end is connected to the pulley assembly 2. The elastic element 3 is used to drive the pulley assembly 2 to slide upward to a first position, so that the pulley assembly 2 has space to slide downward to a second position. When the pulley assembly 2 is not subjected to external force, it slides upward to the first position under the action of the elastic element 3. When the pulley assembly 2 is subjected to an external force exceeding the elastic force of the elastic element 3, it can slide downward to the second position.

[0053] One end of the cable is wound around the output end of the actuator, which can rewind or release the cable when the output end of the actuator rotates. The other end of the cable passes over the pulley assembly 2 and extends downwards to connect to the drying rod. By changing the rotation direction of the output end of the actuator, the drying rod can be switched between the storage position, the drying position, and the hanging position. The storage position, drying position, and hanging position are set sequentially from top to bottom, that is, the height of the storage position, drying position, and hanging position decreases in that order. When the drying rod is in the storage position, it can be stored in the storage slot of the main unit or the ceiling. The storage position is the upper limit of the drying rod, and the drying rod cannot rise further. The drying position is where clothes are dried, and the hanging position is where the user hangs or takes down clothes. After the clothes are hung, the drying rod rises to the drying position for drying. After all the clothes on the drying rod are taken down, the drying rod rises to the storage position for storage.

[0054] In this application, when the drying rod is not hanging any clothes and does not encounter any obstruction as it rises, the external force on the drying rod is insufficient to overcome the tension of the elastic element 3, and the pulley assembly 2 is in the first position. When clothes are hanging on the drying rod or the drying rod encounters obstruction as it rises, the force exerted on the drying rod by the clothes or the resistance to its rise will act on the pulley assembly 2 through the cable, causing the pulley assembly 2 to switch to the second position. The situation where the drying rod encounters obstruction as it rises is generally caused by the drying rod hitting the main unit or other components when it rises from the drying position to the storage position.

[0055] Thus, when the clothes drying rod encounters resistance or hangs clothes, the pulley assembly 2 can switch to the second position and trigger the detection unit 4, causing the drying rod to stop rising or fall back down, preventing it from continuing to rise and hitting the ceiling, thus eliminating safety hazards. This application, through the cooperation of the pulley assembly 2, the elastic element 3, and the detection unit 4, overcomes the tension of the elastic element 3 to achieve the obstacle-encountering and falling-back function with less resistance. Compared to detecting the motor current, this method is more stable and reliable, and can better protect the user's ceiling and clothes drying rack.

[0056] Furthermore, the detection unit 4 is installed on the main unit and communicates with the control unit. When the pulley assembly 2 is in the first position, the pulley assembly 2 cannot trigger the detection unit 4, and the driver continues to drive the drying rack upwards. When the pulley assembly 2 is in the second position, the pulley assembly 2 can trigger the detection unit 4. Whether the driver continues to drive the drying rack upwards depends on the position of the drying rack, and the specific determination process is as follows:

[0057] Judgment process 1: When the pulley assembly 2 is in the first position, there are no clothes on the drying rod and the drying rod rises without being obstructed. The pulley assembly 2 cannot trigger the detection unit 4. When it is necessary to drive the drying rod to rise, the driver will rewind the cable regardless of the position of the drying rod, so that the drying rod rises until the drying rod rises to the position required by the user.

[0058] Judgment Process Two: When pulley assembly 2 is in the second position and the drying rod switches from the hanging position to the drying position, pulley assembly 2 triggers detection unit 4. This means pulley assembly 2 has touched detection unit 4 or reached its detection range. However, detection unit 4 will not send a stop command to the driver via the control unit. The driver continues to reel in the cable until the drying rod reaches the drying position and stops. During this process, pulley assembly 2 switches to the second position because clothes are hanging on the drying rod. If the driver were to drive the drying rod from the hanging position to the drying position at this time, detection unit 4 would not send a stop command to the driver. The driver would continue to drive the drying rod upwards until it reaches the drying position, thus not affecting the drying of clothes and preventing the drying rod from encountering resistance and stopping or falling back during normal use of the clothes dryer.

[0059] Judgment process 3: When the pulley assembly 2 is in the second position and before the drying rod is switched from the drying position to the storage position, the pulley assembly 2 triggers the detection unit 4, and the driver stops winding the cable or releases the cable to make the drying rod descend. During this process, if the clothes hanging on the drying rod are obstructed by the main unit or other components of the clothes drying machine, causing the pulley assembly 2 to be in the second position, and the drying rod is switched from the drying position to the storage position (i.e., the drying position begins to rise), the drying rod, clothes, or clothes hangers may hit the main unit or other components, causing damage to the clothes drying machine. The drive needs to be controlled to prevent damage. Therefore, when the pulley assembly 2 is in the second position, if the drying rod is switched from the drying position to the storage position, before the drying rod reaches the storage slot in the storage position, the pulley assembly 2 triggers the detection unit 4. At this position, the detection unit 4 sends a command to the drive to stop the rewinding cable and then trigger an alarm, or the detection unit 4 sends a command to the drive to release the cable and drive the drying rod back down to the drying position or below it, preventing damage to the clothes drying machine and eliminating safety hazards.

[0060] Judgment Process 4: When pulley assembly 2 is in the first position and the drying rod reaches the storage position, there are no clothes hanging on the drying rod, and the drying rod cannot continue to rise because it has reached the upper limit position. If the driver continues to drive the drying rod to rise at this time, the drying rod will be obstructed. During this process, pulley assembly 2 will trigger detection unit 4, but detection unit 4 will not send a command to the driver to fall back through the control unit. The driver will choose to continue winding the cable or stop winding the cable according to the horizontal state of the drying rod.

[0061] In the fourth judgment process, it is also possible to avoid the inability to properly retract the clothesline due to the ends not being level. When the ends of the clothesline are connected to cables, two pulley assemblies 2 are set up to guide the two cables respectively. When the lengths of the cables at the two ends of the clothesline are different, causing the ends of the clothesline to be not level, for example, the right end of the clothesline is higher than the left end, when the right end of the clothesline rises to the top of the retractable position and touches the top, the actuator continues to wind up the cable at the left end of the clothesline. The left end of the clothesline continues to rise, and the right end of the clothesline encounters resistance at the top of the retractable position. This causes the cable at the right end of the clothesline to exert an external force on the pulley assembly 2 at the right end to overcome the elastic force of the elastic element 3. The pulley assembly 2 can slide so that the actuator can continue to wind up the cable connected to the right end of the clothesline, thereby preventing the clothesline from being unable to be properly retracted. During this process, although the detection unit 4 on the right is triggered, it does not send a stop command to the driver. The driver continues to wind up the cables at both ends of the drying rod until both ends of the drying rod are horizontal, at which point the driver stops winding, allowing the drying rod to be stored normally. When the drying rod reaches the storage position and both ends are exactly horizontal, the driver directly stops winding up the cables.

[0062] In the above-mentioned judgment process four, the control unit can send a stop command to the driver by detecting whether the two ends of the drying rod are horizontal, or by detecting whether the detection units 4 at the left and right ends of the drying rod are triggered at the same time. When the detection units 4 at the left and right ends of the drying rod are triggered at the same time, the control unit sends a stop command to the driver.

[0063] When determining the position of the drying rack in the above four processes, the position can be detected by optical sensors such as infrared sensors, acoustic sensors such as ultrasonic sensors, electromagnetic sensors such as eddy current sensors, the position can be detected by detecting the stroke of the output end of the driver, or the position can be detected by detecting the winding length of the cable, so as to avoid triggering the drying rack's obstruction and fall-back function during normal use.

[0064] In one embodiment, the main unit includes a support frame 1 and a mounting base 5 mounted on the support frame 1. A detection unit 4 is mounted on the mounting base 5 and has a trigger plate 41. When the pulley assembly 2 is in the second position, the pulley assembly 2 abuts against the trigger plate 41, thereby triggering the detection unit 4. Then, the detection unit 4 controls the operation of the driver according to the position of the drying rod.

[0065] Optionally, the detection unit 4 can be an infrared sensor, a thermal sensor, a grating, a micro switch, a spring contact, a Hall sensor, or a reed switch, etc.

[0066] Furthermore, the clothes drying rack with anti-collision function also includes threaded fasteners 6. The support frame 1 is provided with a slot 11, and the mounting base 5 is provided with a mounting platform 51. The mounting base 5 is installed on the support frame 1 by the threaded fasteners 6. The mounting platform 51 engages with the slot 11. The mounting platform 51 is a square protrusion on the back of the mounting base 5, and the slot 11 is a square groove, which realizes the quick installation and positioning of the mounting base 5, so that the detection unit 4 and the pulley assembly 2 can be accurately matched.

[0067] Optionally, the mounting base 5 is provided with a positioning groove 52, which is located on the front side of the mounting base 5. An elastic hook 53 is provided on the inner wall of the positioning groove 52. The elastic hook 53 can undergo elastic deformation. The detection unit 4 is installed in the positioning groove 52 and clamped between the elastic hook 53 and the inner wall of the positioning groove 52. When installing the detection unit 4, the elastic hook 53 undergoes elastic deformation during the pressing process of the detection unit 4 into the positioning groove 52. After the detection unit 4 is pressed into the positioning groove 52, the elastic hook 53 returns to its original deformation, thus clamping the detection unit 4 between the elastic hook 53 and the inner wall of the positioning groove 52, preventing the detection unit 4 from falling off. The elastic hook 53 enables quick installation of the detection unit 4 and also facilitates the disassembly and maintenance of the detection unit 4.

[0068] Furthermore, the mounting base 5 is also provided with a wiring channel 54. The positioning groove 52 is connected to the outside of the mounting base 5 through the wiring channel 54. The detection unit 4 has a pin 42, which passes through the wiring channel 54. The wiring channel 54 facilitates the lead-out of the pin 42, thereby facilitating wiring so that the detection unit 4 can be electrically connected to the driver through the control unit.

[0069] In one embodiment, the pulley assembly 2 includes an axle 21 slidably mounted on the main unit, a guide frame 22 connected to the axle 21, and a roller 23 rotatably mounted on the guide frame 22. One end of the elastic member 3 is connected to the support frame 1 of the main unit, and the other end of the elastic member 3 is connected to the axle 21. The guide frame 22 is slidably mounted on the support frame 1 of the main unit to guide the axle 21 and the roller 23 to slide on the main unit. One end of the elastic member 3 is connected to the axle 21 of the pulley assembly 2, and the other end is fixed to the support frame 1 of the main unit. The elastic member 3 is used to drive the pulley assembly 2 to move upward, so that the pulley assembly 2 has downward space. When the drying rod is subjected to force due to hanging clothes or encounters resistance when rising in the drying position, the cable pulls the pulley assembly 2 downward.

[0070] Optionally, the support frame 1 of the main unit is provided with a mounting port 12 for avoiding the roller 23. The main unit is provided with two support plates 13 located on two opposite sides of the mounting port 12. The support plates 13 are set on the support frame 1, and the wheel axle 21 is slidably mounted on the support plate 13 to realize the up and down sliding of the pulley assembly 2.

[0071] In one embodiment, the support plate 13 has a sliding hole 14, which is a strip-shaped hole extending from top to bottom. The axle 21 has an abutment surface 24, which is located on the outer circumferential side surface of one end of the axle 21 and is parallel to the axis of the axle 21. The axle 21 slides in the sliding hole 14 and the abutment surface 24 abuts against the inner wall of the sliding hole 14, preventing the elastic element 3 from twisting due to the rotation of the axle 21 and preventing the elastic element 3 from being subjected to a force perpendicular to the sliding direction of the pulley assembly 2.

[0072] Furthermore, the guide frame 22 includes side guard plates 25, anti-slip plate 26, and guide plate 27. There are two side guard plates 25, arranged parallel to each other on both sides of the roller 23. One end of each side guard plate 25 is rotatably connected to the wheel axle 21, and the other end is fixedly connected to the anti-slip plate 26. The anti-slip plate 26 is located on the periphery of the roller 23 to prevent the cable from detaching from the groove 28 on the roller 23. Its main function is to prevent the cable from accidentally detaching from the groove 28 on the roller 23. During the operation of the clothes drying machine, changes in cable tension may cause its position on the roller 23 to change, or even detach from the groove 28. The presence of the anti-slip plate 26 effectively prevents this from happening, ensuring the normal operation of the clothes drying machine. At least one of the two side guard plates 25 is provided with a guide plate 27. The pulley support plate 13 is provided with a guide hole 15 for guiding the guide plate 27. The guide plate 27 is embedded in the guide hole 15 to guide the guide frame 22 to slide up and down, so that the guide plate 27 can slide smoothly in the guide hole 15, and the roller 23 can maintain a stable posture when sliding.

[0073] In one embodiment, the driver is a device such as a motor or a cable reel, and the motor's output shaft is equipped with a stroke detection unit. In this embodiment, the position information of the drying rod is obtained by detecting the rotational stroke of the motor's output shaft through the stroke detection unit, which facilitates the control unit to control the driver by combining the triggering information of the detection unit 4 and the position information of the drying rod.

[0074] Furthermore, lift detection switches 7 are installed on both sides of the main unit. These switches 7 are used to detect the lifting height of the drying rod on both sides. The lift detection switches 7 can be infrared sensors, thermal sensors, gratings, microswitches, spring contacts, Hall effect sensors, or reed switches, etc. By detecting the lifting height of the drying rod on both sides using the lift detection switches 7, the driver can be more easily triggered to lower the drying rod when it is in the storage position due to unevenness at both ends.

[0075] Optionally, the main unit has a storage slot located on the path of the drying rod as it moves upwards. When the drying rod is in the storage position, it is located inside the storage slot, thus storing the drying rod.
