Description

Technical Field

[0001] This invention relates to the field of clothes drying racks, and more particularly to a drive reset system and reset method for a clothes drying rack. Background Technology

[0002] There is a type of concealed clothes drying rack, which includes a main unit, a panel assembly with a U-shaped groove, and a height-adjustable drying rod. The main unit and panel assembly are concealed inside the ceiling, and the drying rod can be stored in the U-shaped groove of the panel assembly.

[0003] For example, the concealed single-pole clothes drying rack with publication number CN113265857A includes: a casing, in which a lifting motor assembly is installed, and fixed pulleys are provided on both sides of the casing; a concealed box, the bottom of which has a groove for accommodating the clothes drying rod, and the top of which has a through hole for passing through a steel wire rope; and a clothes drying rod, in which the steel wire rope passes through the fixed pulleys and the concealed box in sequence and is fixedly connected to the clothes drying rod; wherein, the clothes drying rod is located directly below the concealed box.

[0004] If a user forgets to remove the clothes rack from the drying rack, the clothes rack may get stuck in the U-shaped groove during the process of the drying rack being raised. This will prevent the drying rack from being retracted into the U-shaped groove, causing the steel wire rope to jam. Specifically, one side of the steel wire rope will be in a slack state, while the other side will be in a taut state.

[0005] The reason for the above-mentioned wire rope jamming is that the mechanism assembly is equipped with an obstacle detection switch on both sides, including a micro switch and a roller seat. The wire rope passes through the roller seat. When the wire rope is taut under load, the roller seat moves away from the micro switch, and the spring on the micro switch is in the loose state. However, when the wire rope is slack, the roller seat moves closer to the micro switch, triggering the lifting motor to stop.

[0006] In this situation, the user cannot use the clothes drying rack and needs a professional repairman to come to the user's home to disassemble and repair it, which is time-consuming and laborious. Summary of the Invention

[0007] To address the problem of the lifting motor stopping due to the slack in the steel wire rope caused by forgetting to remove foreign objects, this invention provides a clothes drying drive reset system and method. By tightening the steel wire rope, the lifting motor is re-triggered, and then the clothes drying rod is controlled to descend so that the clothes drying machine can resume its drive system after the foreign object is removed.

[0008] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a clothes drying rack drive reset system, characterized in that it includes a main body housing and a control circuit disposed in the main body housing, two winding reels synchronously driven by a lifting motor and steel wire ropes extending from each winding reel to both sides, wherein the steel wire ropes are connected vertically downward to the end of the drying rod after passing through a steering wheel; each side of the winding reel is provided with a relaxation trigger connected to the control circuit, and a tensioning device is provided between the relaxation trigger and the steering wheel;

[0009] The tensioning device includes a first rotating wheel seat with a first threading groove and a driver that can drive the first rotating wheel seat to move a certain distance;

[0010] The steel wire rope passes sequentially through the first threading groove of the slack trigger and the tensioning device;

[0011] When the slack trigger detects that the passing wire rope is slack, the slack trigger can trigger a signal to the control circuit, which controls the lifting motor to stop rotating and the drying pole to stop rising.

[0012] When the control circuit receives a reset command, the control circuit controls the driver to move the first rotating seat a certain distance. The movement distance of the first rotating seat can tighten the slack wire rope to a taut state. The slack trigger can trigger a signal to the control circuit to put the lifting motor in a standby state. After receiving the user's descent command, the control circuit controls the lifting motor to run in reverse so that the drying rack is lowered.

[0013] A further preferred embodiment of the present invention is as follows: the relaxation trigger includes a second base, a second rotating wheel seat with a second wire groove, and a micro switch, wherein the micro switch is mounted on the second base;

[0014] A tension spring is provided between the second base and the second rotating wheel seat;

[0015] The second rotary wheel base is provided with a pressing member; the pressing member can pass through the slot of the second base and act on the micro switch;

[0016] The wire rope passes through the second threading groove of the second wheel seat under tension. The tension of the wire rope overcomes the force of the tension spring, and the top pressure component does not touch the micro switch.

[0017] When the wire rope is in a slack state, the tension spring pulls the second rotating wheel seat towards the micro switch. The top pressure member on the second rotating wheel seat touches the spring plate of the micro switch, and the micro switch triggers the lifting motor to stop rotating.

[0018] A further preferred embodiment of the present invention is as follows: the second wheel seat includes a second U-shaped frame and a second wheel; the second wheel is axled on the second U-shaped frame and forms a threading groove for the wire rope to pass through.

[0019] A further preferred embodiment of the present invention is as follows: the tensioning device further includes a first base, and the driver is an electromagnet, which is mounted on the first base;

[0020] The first rotating wheel seat includes a first U-shaped frame and a first rotating wheel, the first rotating wheel shaft is connected to the first U-shaped frame and forms a first threading groove;

[0021] The back of the first U-shaped frame is provided with two connecting pieces, and a connecting groove is formed between the two connecting pieces. The driving head of the electromagnet is connected to the connecting groove.

[0022] The first base is provided with corresponding cavities for inserting connecting pieces and driving heads.

[0023] A further preferred embodiment of the present invention is as follows: an arched bracket is provided at the bottom of the main unit housing, and the first base is fixed on the arched bracket by screws.

[0024] Another topic: a method for resetting the drive of a clothes drying rack, including a main housing and a control circuit located within the main housing, two winding reels synchronously driven by a lifting motor, and steel wire ropes extending from each winding reel to both sides, wherein the steel wire ropes are connected vertically downward to the end of the drying rod after passing through a steering wheel;

[0025] A slack trigger connected to the control circuit is provided on each side of the winding reel, and a tensioning device is provided between the slack trigger and the steering wheel.

[0026] The specific steps are as follows;

[0027] 1) When the slack trigger detects that the wire rope is slack, the slack trigger can send a signal to the control circuit, which controls the lifting motor to stop rotating and the drying rack to stop rising.

[0028] 2) When the control circuit receives the user's reset command, the control circuit controls the driver to drive the first wheel seat to move a certain distance, and the movement distance of the first wheel seat pulls the slack wire rope to a taut state.

[0029] 3) After the relaxation trigger is triggered by the tension of the taut wire rope, it sends the tension signal to the control circuit, so that the lifting motor is in standby mode.

[0030] 4) The control circuit receives the user's command to lower the drying pole. The control circuit drives the lifting motor to rotate in the opposite direction. The winding reel driven by the lifting motor releases the wire rope, and the wire ropes on both sides reach a state of balanced tension.

[0031] 5) Once the drying rack has been lowered to the appropriate height, the user can remove the foreign object from the rack.

[0032] A further preferred embodiment of the present invention is as follows: the relaxation trigger includes a second base, a second rotating wheel seat with a second wire groove, and a micro switch, wherein the micro switch is mounted on the second base;

[0033] A tension spring is provided between the second base and the second rotating wheel seat;

[0034] The second rotary wheel base is provided with a pressing member; the pressing member can pass through the slot of the second base and act on the micro switch;

[0035] The wire rope passes through the second threading groove of the second wheel seat under tension. The tension of the wire rope overcomes the force of the tension spring, and the top pressure component does not touch the micro switch.

[0036] When the wire rope is in a slack state, the tension spring pulls the second rotating wheel seat towards the micro switch. The top pressure member on the second rotating wheel seat touches the spring plate of the micro switch, and the micro switch triggers the lifting motor to stop rotating.

[0037] A further preferred embodiment of the present invention is as follows: the second wheel seat includes a second U-shaped frame and a second wheel; the second wheel is axled on the second U-shaped frame and forms a second threading groove for the wire rope to pass through.

[0038] A further preferred embodiment of the present invention is as follows: the tensioning device further includes a first base, and the driver is an electromagnet, which is mounted on the first base;

[0039] The first rotating wheel seat includes a first U-shaped frame and a first rotating wheel, the first rotating wheel shaft is connected to the first U-shaped frame and forms a first threading groove;

[0040] The back of the first U-shaped frame is provided with two connecting pieces, and a connecting groove is formed between the two connecting pieces. The drive head of the electromagnet is connected in the connecting groove.

[0041] The first base is provided with corresponding cavities for inserting connecting pieces and driving heads.

[0042] A further preferred embodiment of the present invention is as follows: an arched bracket is provided at the bottom of the main unit housing, and the first base is fixed on the arched bracket by screws.

[0043] Compared with the prior art, the advantages of the present invention are: the slack trigger and the tensioning device are combined in the same clothes drying lifting system. When the rising clothes drying rod gets stuck with foreign objects or gets unexpectedly stuck and cannot continue to rise, the wire rope will slack. At this time, the slack trigger will detect the wire rope slack signal and send the signal to the control circuit to stop the lifting motor from rotating and the clothes drying rod from rising, so that the maintenance personnel can carry out further inspection.

[0044] When the tensioning device receives a reset signal, it is controlled by the control circuit to tighten the steel wire rope and sends the tightened signal back to the control circuit. The control circuit then controls the lifting motor to be ready to operate at any time so that the drying rack can be lowered for maintenance.

[0045] The reset technology solution of the aforementioned clothes drying upgrade system, through the control circuit as the information distribution center, and in conjunction with the two target technical units of slack trigger and tensioning device, is designed to address the situation where the clothes drying machine unexpectedly jams: the drying rod cannot continue to rise, the steel wire rope becomes slack, and then the slack trigger is triggered to start the emergency stop logic; the slack trigger switches its own start-stop logic based on the state of "whether the steel wire rope is taut or not", and the tensioning device uses this principle, as long as the steel wire rope is tightened in the slack state, the slack trigger will be triggered again to guide the start logic, so that the control circuit can control the raising and lowering of the drying rod again.

[0046] The aforementioned reset system has a simple structure, convenient installation of each unit component, clear operating logic, and is easy for users to operate. Furthermore, maintenance personnel can use this reset system to lower the drying rack again, facilitating disassembly or further maintenance work, making the process faster and less strenuous.

[0062] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0063] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0064] like Figure 1 and Figure 2 The diagram shown is a schematic diagram of a clothes drying rack according to a preferred embodiment of the present invention. Figure 1 This is the normal lifting and lowering state of the drying rack (30mm). Figure 2 This is a schematic diagram illustrating a situation where the clothes drying rod 30 unexpectedly becomes stuck. It should be noted that electric clothes drying racks are typically equipped with an emergency start-stop system. When a foreign object suddenly becomes stuck in the drying rod 30 during its ascent, or the steel cable becomes slack, the trigger unit will activate the emergency start-stop logic, stopping the drying rod 30 from rising further to facilitate subsequent maintenance. However, in this situation, because the clothes drying rack is installed at a high position, the drying rod 30 is in a high position, making maintenance work difficult to perform quickly. Based on this problem, this invention designs a drive reset system that allows the unexpectedly stuck drying rod to descend again, facilitating the removal of foreign objects or disassembly of the drying rod by maintenance personnel. The specific solution is as follows:

[0065] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the clothes drying rack drive reset system 100 includes a main housing 101 and a control circuit w disposed in the main housing 101, two winding reels 102 synchronously driven by the lifting motor T, and steel wire ropes 13 extending from each winding reel 102 to both sides. The steel wire ropes 13 are connected vertically downward to the end of the drying rod 30 after passing through the steering wheel 20.

[0066] A relaxation trigger 60 connected to the control circuit w is provided on each side of the winding reel 102, and a tensioning device 40 is provided between the relaxation trigger 60 and the steering wheel 20.

[0067] The tensioning device 40 includes a first wheel seat 41 with a first threading groove h1 and a driver 50 capable of driving the first wheel seat 41 to move a certain distance. The wire rope 13 passes sequentially through the slack trigger 60 and the first threading groove h1 of the tensioning device 40.

[0068] When the slack trigger 60 detects that the passing wire rope 13 is slack, the slack trigger 60 can trigger a signal to the control circuit w, and the control circuit w controls the lifting motor T to stop rotating, and the drying rod 30 to stop rising.

[0069] When the control circuit w receives a reset command, it controls the driver 50 to move the first rotating wheel seat 41 a certain distance. The movement of the first rotating wheel seat 41 can tighten the slack wire rope 13 to a taut state. The tension signal triggers the slack trigger 60, which sends a signal to the control circuit w to put the lifting motor T into a standby state. After receiving the user's descent command, the control circuit w controls the lifting motor T to reverse and lower the drying rack 30.

[0070] It should be noted that when the slack trigger 60 is activated by the taut steel wire rope 13, the slack trigger 60 sends a signal to the control circuit w, which in turn causes the control circuit w to put the lifting motor T back into a standby state. Further control of the drying rack's ascent or descent will then depend on the user's actual needs. Preferably, the control circuit w can also directly convert the taut signal from the slack trigger 60 into a signal to directly lower the drying rack 30, thus quickly lowering it and promptly removing any foreign objects to prevent squeezing or friction.

[0071] The advantage of this invention is that the slack trigger 60 and the tensioning device 40 are combined in the same clothes drying lifting system. When the rising clothes drying rod 30 gets stuck with foreign objects or gets unexpectedly stuck and cannot continue to rise, the wire rope 13 will slack. At this time, the slack trigger 60 will detect the slack signal of the wire rope 13 and send the signal to the control circuit w so that the lifting motor T stops rotating and the clothes drying rod 30 stops rising, so that the maintenance personnel can further inspect and repair it.

[0072] When the tensioning device 40 receives a reset signal, it is controlled by the control circuit w to tighten the wire rope 13 and sends the signal of the tightened wire rope 13 back to the control circuit w. The control circuit w then controls the lifting motor T to be ready to operate at any time so that the drying rack 30 can be lowered for maintenance.

[0073] The reset technology of the aforementioned clothes drying upgrade system, through a centralized control circuit w, and in conjunction with two target technology units, the slack trigger 60 and the tensioning device 40, is designed to address situations where the clothes drying machine unexpectedly jams: the drying rod 30 cannot continue to rise, the steel wire rope 13 becomes slack, and then the slack trigger 60 is triggered to initiate the emergency stop logic; the slack trigger 60 switches its own start-stop logic based on the state of "whether the steel wire rope is taut or not". The tensioning device 40 utilizes this principle, and only needs to tighten the steel wire rope 13 in a slack state to trigger the slack trigger 60 again to guide the start logic, so that the control circuit w can control the raising and lowering of the drying rod 30 again.

[0074] The aforementioned reset system has a simple structure, convenient installation of each unit component, clear operating logic, and is easy for users to operate. Furthermore, maintenance personnel can use this reset system to lower the drying rack again, facilitating disassembly or further maintenance work, making the process faster and less strenuous.

[0075] Specifically, such as Figure 3 , Figure 4 , Figures 7 to 9 , Figure 12 As shown, the relaxation trigger 60 includes a second base 61, a second wheel seat 62 with a second wire groove h2, and a micro switch 63.

[0076] The micro switch 63 is installed on one side of the second base 61, and a tension spring 64 is provided between the second base 61 and the second rotating wheel seat 62; a pressing member 65 is provided on the second rotating wheel seat 62; the pressing member 65 can pass through the slot t of the second base 61 and act on the micro switch 63.

[0077] When the wire rope 13 is taut, it passes through the second threading groove h2 of the second wheel seat 61. The tension of the wire rope 13 overcomes the force of the tension spring 64. At this time, the top pressure member 65 does not touch the micro switch 63.

[0078] When the wire rope 13 is in a slack state, the tension spring 64 pulls the second rotating wheel seat 62 to move towards the micro switch 63. The top pressure member 65 on the second rotating wheel seat 62 touches the spring plate of the micro switch 63, and the micro switch 63 triggers the lifting motor T to stop rotating.

[0079] Preferably, the top pressing member 65 consists of two parallel inserts, with through holes at the outer ends of the inserts, a fixed shaft passing through the through holes, and one end of the tension spring 64 connected to the fixed shaft.

[0080] The second wheel seat 61 includes a second U-shaped frame f1 and a second wheel f2; the second wheel f2 is axled on the second U-shaped frame f1 and forms a second threading groove h2 for the wire rope 13 to pass through. The second wheel f2 is preferably a rubber wheel, which can increase the friction between the wheel and the wire rope 13 and reduce the wear on the wire rope 13 over a long period of time.

[0081] Additionally, it should be noted regarding the tensioning device 40 that, as Figures 9 to 11 As shown, the tensioning device 40 also includes a first base 42, and the driver 50 is an electromagnet G, which is mounted on the first base 42.

[0082] It should be noted that the first rotating wheel seat 41 is fixed to one side of the first base 42, while the driver 50 is installed on the other side of the first base 42, and the first rotating wheel seat 41 and the driver 50 are fixedly connected inside the first base 42.

[0083] The first rotating wheel seat 41 includes a first U-shaped frame d1 and a first rotating wheel d2. The first rotating wheel d2 is shaft-connected to the first U-shaped frame d1 and forms a first threading groove h1.

[0084] The back of the first U-shaped frame d1 is provided with two connecting pieces d3, and a connecting groove d4 is formed between the two connecting pieces d3. The driving head G1 of the electromagnet G is connected in the connecting groove d4.

[0085] The first base 42 has corresponding cavities for inserting the connecting piece d3 and the driving head G1. Specifically, insertion slots are provided on both sides of the first base 42, and the insertion slots on both sides are interconnected. After the connecting piece d3 and the driving head G1 are inserted into the insertion slots, they can be connected and fixed to each other. When the electromagnet G receives a signal from the control circuit w, it will drive the connecting piece d3 to move, thereby causing the tensioning device 40 to tighten the slack steel wire rope 13.

[0086] Preferably, an arched bracket g is provided at the bottom of the main unit housing 101, and the first base 42 is fixed to the arched bracket g by screws r. The arched bracket g includes a crossbar and fixed sections extending outward from both sides of the bottom, and the fixed sections are installed inside the main unit housing 101 by fasteners. The first base 42 is fixed to the crossbar by screws r.

[0087] The specific steps for resetting the clothes drying rack drive are as follows:

[0088] 1) such as Figure 13 As shown, the slack trigger 60 detects that the wire rope 13 is slack, and the slack trigger 60 can trigger a signal to the control circuit w. The control circuit w controls the lifting motor T to stop rotating, and the drying rod 30 stops rising.

[0089] 2) such as Figure 14As shown, when the control circuit w receives the user's reset command, the control circuit w controls the driver 50 to move the first rotating seat 41 of the tensioning device 40 a certain distance. The movement of the first rotating seat 41 pulls the slack wire rope 13 to a taut state. At this time, the slack trigger 60 is triggered by the tension of the taut wire rope 13 and then sends the tension signal to the control circuit w, putting the lifting motor in a standby state. After the control circuit w receives the user's descent command, it controls the lifting motor T to reverse and lower the drying rack 30.

[0090] Preferably, the control circuit w can directly convert the tension signal transmitted from the relaxation controller 60 into a command to lower the drying rod 30, and promptly control the lifting motor T to rotate, without waiting for the user to send another lowering command to the control circuit w. This allows the drying rod 40 to lower in a timely manner, so that foreign objects can be removed or the drying rod 30 can be disassembled.

[0091] 3) Alternatively, the user can send a descent command to the control circuit w. When the control circuit w receives the user's command to lower the drying pole 30, the control circuit w drives the lifting motor T to rotate in the opposite direction. The winding reel 102 driven by the lifting motor T releases the wire rope 13, and the wire ropes 13 on both sides reach a balanced tension state.

[0092] 4) When the drying rod 30 is lowered to a suitable height, the user removes the foreign object from the drying rod 30.

[0093] The slack trigger 60 and the tensioning device 40 are integrated into the same clothes drying lifting system. When the rising clothes drying rod 30 becomes stuck with foreign objects or unexpectedly jams and cannot continue to rise, it will cause the steel wire rope 13 to slack. This is the emergency start-stop operation logic of the clothes drying machine formed around the slack trigger 60. Specifically, the slack trigger 60 will detect the slack signal of the steel wire rope 13 and send the signal to the control circuit to stop the lifting motor from rotating and the clothes drying rod from rising, so that maintenance personnel can further inspect and repair it.

[0094] When the tensioning device 40 receives a reset signal, it is controlled by the control circuit w to tighten the steel wire rope 13 and sends the tightened signal back to the control circuit w. The control circuit w then controls the lifting motor T to be ready to operate at any time, so that the drying rack 30 can be lowered for maintenance. This is the reset operation logic surrounding the tensioning device 40 that this invention aims to highlight. This technical solution not only focuses on the tensioning device 40 and its surrounding technical means, but more importantly, on the interaction between the tensioning device 40 and the relaxation trigger 60. By using the control circuit w as the information distribution center, and in conjunction with the two target technical units, the slack trigger 60 and the tensioning device 40, the system is designed to address situations where the clothes drying rack unexpectedly jams: the drying rod 30 cannot continue to rise, the steel wire rope 13 becomes slack, and then the slack trigger 60 is triggered to start the emergency stop logic; the slack trigger 60 switches its own start-stop logic based on the state of "whether the steel wire rope is taut or not". The tensioning device 40 utilizes this principle, and only needs to tighten the steel wire rope 13 in the slack state to trigger the slack trigger 60 again to guide the start logic, so that the control circuit w can control the raising and lowering of the drying rod 30 again.

[0095] The aforementioned reset system has a simple structure, convenient installation of each unit component, clear operating logic, and is easy for users to operate. Furthermore, maintenance personnel can use this reset system to lower the drying rack again, facilitating disassembly or further maintenance work, making the process faster and less strenuous.

[0096] The above describes the drive reset system and reset method provided by the present invention. Specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the present invention and its core ideas.

[0097] It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.

The specific steps are as follows; 1) When the slack trigger detects that the wire rope is slack, the slack trigger can send a signal to the control circuit, which controls the lifting motor to stop rotating and the drying rack to stop rising; 2) When the control circuit receives the user's reset command, the control circuit controls the driver to move the first wheel seat a certain distance, and the movement distance of the first wheel seat pulls the slack wire rope to a taut state. 3) After the relaxation trigger is triggered by the tension of the taut wire rope, it sends the tension signal to the control circuit, so that the lifting motor is in standby mode. 4) The control circuit receives the user's command to lower the drying pole. The control circuit drives the lifting motor to rotate in the opposite direction. The winding reel driven by the lifting motor releases the wire rope, and the wire ropes on both sides reach a state of balanced tension. 5) Once the drying rack has been lowered to the appropriate height, the user can remove the foreign object from the rack.
