Description

Technical Field

[0001] The utility model relates to the technical field of clothes drying machines, in particular to an integrated resistance limiting mechanism, a power device and a clothes drying machine. Background Art

[0002] Clothes drying machines have become a necessity in many households. As consumer demand for these machines continues to grow, so too has the demand for smarter, more and more functional modules, such as lifting, drying, and disinfecting, have been added. To enhance safety, these machines often incorporate stop-on-obstruction and limit-stop functions.

[0003] The resistance structure and limit structure of the existing clothes drying machine are independently arranged in the clothes drying machine main body. Usually, the resistance structure is set close to the motor in the middle, and the limit structure is set at both ends of the main body, and the limit switch is triggered by the clothes drying rod or bracket of the clothes drying machine. Under this setting method, the resistance structure and the limit structure are far apart, which makes the wiring inside the clothes drying machine main body extremely complicated, and at the same time affects the assembly and maintenance of the product, and has great limitations on use. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an integrated resistance limiting mechanism, which integrates the resistance structure and the limiting structure on an integrated bracket at the same time, and realizes the functions of stopping when encountering resistance and stopping when limiting by detecting the changes in the contact state of the traction rope, the resistance structure and the limiting structure. The overall structure is simple, easy to disassemble and assemble, and has strong applicability.

[0005] Another object of the present invention is to provide a power device that is easy to install and can simplify the wiring of the power device by directly fixing the integrated resistance limiting mechanism to the line outlet side of the winding wheel.

[0006] Another object of the present invention is to provide a clothes drying machine that is easy to assemble and maintain later by adopting an integrated resistance limiting mechanism with high integration.

[0010] Furthermore, the resistance structure includes an resistance detection component and an resistance trigger component that can movably contact the resistance detection component; the resistance detection component is fixed on the integrated bracket, and the resistance trigger component is movably connected to the integrated bracket. When the traction rope is in a tensioned state, the resistance trigger component is pulled to keep the resistance trigger component in contact with or away from the resistance detection component; when the traction rope is relaxed, the contact state between the resistance trigger component and the resistance detection component changes.

[0011] Furthermore, the resistance triggering member is provided with an elastic member and a contact member, and the contact member is connected to the integrated bracket through the elastic member; when the traction rope is in a tensioned state, it contacts the contact member to pull the elastic member to produce elastic deformation; when the traction rope is in a relaxed state, the elastic member is deformed and restored to allow the contact member to contact the resistance detection member.

[0012] Furthermore, the abutment member is provided with a wire outlet hole, and the traction rope passes through the wire outlet hole in a tensioned state to pull the abutment member.

[0013] Furthermore, the abutment member further includes a rotating portion, which is rotatably connected to the integrated bracket and can rotate relative to the integrated bracket under the action of the traction rope or the elastic member.

[0014] Furthermore, the position limiting structure includes a position limiting detection component, which is fixed to the integrated bracket, and the position limiting detection component is triggered when the traction rope moves around the winding wheel to the corresponding limit position.

[0015] Furthermore, the limiting structure also includes a limiting trigger component, which is rotatably connected to the integrated bracket. When the traction rope runs to the limiting position, it abuts against the limiting trigger component and drives the limiting trigger component to rotate to trigger the limiting detection component.

[0016] A power device comprising:

[0017] The device body is provided with a motor and at least one winding wheel, and the motor drives the winding wheel to rotate;

[0018] At least one set of the integrated resistance limiting mechanism described in the utility model is fixedly connected to the device body and is arranged on the line outlet side of the winding wheel.

[0020] A clothes drying machine comprises the power device described in the utility model.

[0021] The beneficial effects of the present invention are:

[0022] (1) By integrating the resistance structure and the limiting structure on an integrated bracket, the functions of stopping when encountering resistance and stopping when limiting are realized by detecting the change in the contact state between the traction rope and the resistance structure and the limiting structure.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0038] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0039] See also Figure 1 and Figure 2, an embodiment of the present application provides an integrated resistance limiting mechanism for detecting the state of the traction rope 300 wound by the reel 210. The integrated resistance limiting mechanism 100 includes: an integrated bracket 10, and an resistance structure 20 and at least one limiting structure 30 provided on the integrated bracket 10; the integrated bracket 10 is fixed on the line-out side of the reel 210, and the traction rope 300 can contact the resistance structure 20 and the limiting structure 30 during the movement around the reel 210. The resistance structure 20 and the limiting structure 30 are both provided with detection components for monitoring changes in the contact state of the traction rope 300 with the resistance structure 20 and the limiting structure 30. The traction rope 300 maintains stable contact with the resistance structure 20 in a tensioned state. When the traction rope 300 is relaxed, the contact state with the resistance structure 20 changes, and the detection component of the resistance structure 20 is triggered. When the traction rope 300 moves to the limit position on the stable winding reel 210, the contact state with the limit structure 30 changes, and the detection element of the limit structure 30 is triggered. After the detection element is triggered, a signal is fed back to the motor 220 that controls its movement, and the motor 220 responds accordingly, thereby reducing safety hazards.

[0040] The integrated resistance limiting mechanism 100 provided in the embodiment of the present application integrates the resistance structure 20 and the limiting structure 30 on an integrated bracket 10 at the same time, and realizes the functions of stopping when resistance is encountered and stopping when limiting by detecting the changes in the contact state of the traction rope 300 and the resistance structure 20 and the limiting structure 30. The overall structure is simple, easy to assemble and disassemble, and has strong applicability.

[0041] See also Figure 1-4 Furthermore, in some embodiments, the integrated bracket 10 is provided with a limiting hole 11 for the traction rope 300 to pass through. The traction rope 300 can move from one end limit to the other end limit in the limiting hole 11. The resistance structure 20 and the limiting structure 30 are both provided on the periphery of the limiting hole 11. The traction rope 300 passes through the limiting hole 11 and moves between the two limit ends. At this time, the traction rope 300 maintains force contact with the resistance structure 20. When the traction rope 300 relaxes and the force contact with the resistance structure 20 is released, the detection component of the resistance structure 20 detects the change in contact state and triggers the detection component. At the same time, after the traction rope 300 moves to the limit position, it contacts the limiting structure 30 provided there, triggering the detection component of the limiting structure 30.

[0042] Furthermore, in some embodiments, the resistance structure 20 includes a resistance detection member 21 and a resistance trigger member 22 that can movably contact the resistance detection member 21. The resistance detection member 21 is fixedly mounted on the periphery of the limiting hole 11, and the resistance trigger member 22 is movably connected to the integrated bracket 10 and is pulled by the traction rope 300 to be located outside the limiting hole 11. When the traction rope 300 is in a tensioned state, it pulls the resistance trigger member 22 so that it contacts or moves away from the resistance detection member 21; when the traction rope 300 is in a relaxed state, the contact state between the resistance trigger member 22 and the resistance detection member 21 changes.

[0043] It is understandable that the resistance detection member 21 and the resistance trigger member 22 can have two modes of action: when the traction rope 300 is in a tensioned state, the resistance trigger member 22 is pulled to maintain contact with the resistance detection member 21; when the traction rope 300 encounters resistance and relaxes, the resistance trigger member 22 moves away from the resistance detection member 21, at which point the resistance detection member 21 detects a change in the contact state between the two and feeds back a signal to the motor 220, causing the motor 220 to stop working. Alternatively, when the traction rope 300 is in a tensioned state, the resistance trigger member 22 is pulled away from the resistance detection member 21; when the traction rope 300 encounters resistance and relaxes, the resistance trigger member 22 contacts the resistance detection member 21; at which point the resistance detection member 21 detects a change in the contact state between the two and feeds back a signal to the motor 220, causing the motor 220 to stop working.

[0044] See also Figure 2 and Figure 3 Furthermore, the resistance triggering member 22 is provided with an elastic member 222 and an abutting member 221, and the abutting member 221 is elastically connected to the integrated bracket 10 through the elastic member 222; when the traction rope 300 is in a tensioned state, it abuts against the abutting member 221, causing the elastic member 222 to produce elastic deformation. When the traction rope 300 is relaxed, the elastic member 222 recovers its deformation and generates elastic force to make the abutting member 221 contact the resistance detecting member 21.

[0045] Furthermore, in some embodiments, the abutment member 221 is provided with a wire outlet hole 2211, and a rotatable roller 2212 is provided in the wire outlet hole 2211. When the traction rope 300 is in a tensioned state, it passes through the wire outlet hole 2211 and abuts against the roller 2212, thereby pulling the abutment member 221. At the same time, when the traction rope 300 is in a moving state, it can drive the roller 2212 to rotate, thereby reducing the relative friction between the traction rope 300 and the roller 2212, preventing wear of the traction rope 300, and increasing the service life of the traction rope 300.

[0046] Specifically, the movable connection between the abutment 221 and the integrated bracket 10 is a rotational connection or a sliding connection. In some embodiments, the abutment 221 is slidably connected to the integrated bracket 10. In this arrangement, one end of the elastic member 222 is fixed to the integrated bracket 10, and the other end is connected to the abutment 221. When the traction rope 300 is relaxed, the traction force on the abutment 221 disappears, and the elastic force of the elastic member 222 pulls the abutment 221 into contact with or away from the resistance detection member 21. It is understood that in this arrangement, the elastic member 222 is a component such as a spring that can pull the abutment 221 to perform linear motion relative to the integrated bracket 10, but the present invention is not limited to this.

[0047] In some other embodiments, the abutment 221 is rotatably connected to the integrated bracket 10. In this case, the abutment 221 further includes a rotating portion 2213, which is rotatably connected to the integrated bracket 10. One end of the elastic member 222 is fixed to the integrated bracket 10, and the other end is connected to the abutment 221. When the traction rope 300 is loosened, the traction force on the abutment 221 disappears, and the elastic force of the elastic member 222 drives the abutment 221 to rotate around the rotating portion 2213 to achieve contact with or distance from the resistance detection member 21. It is understandable that in this arrangement, the elastic member 222 can be a component such as a spring, a torsion spring, or a spring clip that pulls the abutment 221 to rotate relative to the integrated bracket 10, but is not limited to this.

[0048] See also Figure 2 and Figure 4-6 Furthermore, in some embodiments, the limiting structure 30 includes a limiting detection member 301, which is fixed to the integrated bracket 10 and disposed on the periphery of the limiting hole 11, partially covering the limiting hole 11. When the traction rope 300 moves around the winding reel within the limiting hole 11 to the corresponding limiting position, the limiting detection member 301 is triggered. In this configuration, the limiting structure 30 is a linear triggering structure, and the limiting detection member 301 is directly triggered by the traction rope 300.

[0049] See also Figure 5 Furthermore, in some other embodiments, the position limiting structure 30 includes a position limiting detection member 301 and a position limiting trigger member 302. The position limiting detection member 301 is fixed to the integrated bracket 10; the position limiting trigger member 302 is rotatably connected to the integrated bracket 10, is arranged on the outer periphery of the position limiting hole 11, and partially covers the position limiting hole 11. When the traction rope 300 runs in the position limiting hole 11 to the limit position, it abuts one end of the position limiting trigger member 302 and drives the position limiting trigger member 302 to rotate so that its other end triggers the position limiting detection member 301. In this arrangement, the position limiting structure 30 is a rotation trigger structure, and the position limiting trigger member 302 is triggered by the position limiting trigger member 302 driven by the traction rope 300 to rotate.

[0050] As a specific embodiment, the limit structure 30 includes an upper limit structure and / or a lower limit structure; the upper limit structure is provided with an upper limit detection member, and the lower limit structure is provided with a lower limit detection member; when the traction rope 300 moves around to the upper limit, the upper limit detection member is triggered; when the traction rope 300 moves to the lower limit, the lower limit detection member is triggered. In some embodiments, the upper limit structure and the lower limit structure can be the same linear trigger structure or rotation trigger structure. In other embodiments, the upper limit structure and the lower limit structure can be different, one of which is a linear trigger structure and the other is a rotation trigger structure. It is understandable that the specific settings of the upper limit structure and the lower limit structure can be determined according to the size of the integrated bracket or other actual conditions, which will not be described in detail here.

[0051] See also Figure 1 、 Figure 7 and Figure 8 The embodiment of the present application further provides a power device, including a device body 200 and at least one integrated resistance limiting mechanism 100. The device body 200 includes a motor 220, a gearbox 230, and at least one winding wheel 210 disposed inside the gearbox 230. The traction rope 300 is wound around the winding wheel 210, and the motor 220 drives the winding wheel 210 to rotate, so that the traction rope 300 can move around the winding wheel 210 between the upper limit and the lower limit. The integrated resistance limiting mechanism 100 is fixed to the gearbox 230 via an integrated bracket 10 and is disposed on the line outlet side of the winding wheel 210.

[0052] As a preferred embodiment, the device body 200 is provided with two sets of the winding reels 210, and two sets of integrated resistance limiting mechanisms 100 are respectively provided on the line outlet side of the two winding reels 210. Both sets of integrated resistance limiting mechanisms 100 include a resistance structure 20 and a limiting structure 30. One integrated resistance limiting mechanism 100 is used to detect the resistance and upper limit status of the traction rope 300, and the other integrated resistance limiting mechanism 100 is used to detect the resistance and lower limit status of the traction rope 300. In this way, the structure of the integrated resistance limiting mechanism 100 can be simplified while ensuring safety performance, saving production costs.

[0053] Specifically, the two sets of integrated resistance limiting mechanisms 100 are respectively defined as a first resistance limiting mechanism 101 and a second resistance limiting mechanism 102, wherein the first resistance limiting mechanism 101 is provided with a resistance structure 20 and an upper limit structure 31, and the second resistance limiting mechanism 102 is provided with a resistance structure 20 and a lower limit structure 32. Preferably, the upper limit structure 31 is a linear trigger structure including an upper limit detection member 311, and the lower limit structure 32 is a rotation trigger structure including a lower limit detection member 321 and a lower limit trigger member 322. Under this setting mode, both the upper limit detection member 311 and the lower limit detection member 321 can be set close to the upper limit, thereby reducing the size of the integrated bracket 10, reducing the thickness of the clothes drying machine main unit, and improving the applicability of the power device.

[0054] It is understood that in other embodiments, the upper limit structure 31 can also be configured as a rotational trigger structure, and the lower limit structure 32 can also be configured as a linear trigger structure. Alternatively, in other embodiments, the upper limit structure 31 and the lower limit structure 32 can both be linear trigger structures or rotational trigger structures, without limitation.

[0055] An embodiment of the present application also provides a clothes drying machine, comprising a power device disposed in a main body of the clothes drying machine.

[0056] Compared with the prior art, the beneficial effects of the embodiments of the present application are:

[0057] (1) By integrating the resistance structure and the limiting structure on an integrated bracket, the functions of stopping when encountering resistance and stopping when limiting are realized by detecting the change in the contact state between the traction rope and the resistance structure and the limiting structure. The overall structure is simple, easy to assemble and disassemble, and has strong applicability.

[0058] (2) By directly fixing the integrated resistance limit mechanism to the outlet side of the reel, it is easy to install, which can simplify the wiring of the power device and facilitate assembly and subsequent maintenance;

[0059] (3) By arranging the upper limit structure and the lower limit structure on both sides of the power unit, the structure of the integrated obstacle limit mechanism can be simplified, saving costs;

[0060] (4) A linear trigger structure or a rotary trigger structure can be used to realize the detection of upper and lower limits, which has high flexibility and strong applicability. It can reduce the size of the integrated resistance limit mechanism, reduce the thickness of the clothes drying machine main unit, and improve the integrity and aesthetics of the clothes drying machine.

[0061] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
