[0030] Please refer to Figures 1-3 , the embodiment of the present application provides a lifting device, which is applied to an electric clothes dryer and is arranged between a driving device 20 and a clothes drying rod assembly 30. The lifting device includes: two sets of steering mechanisms 11 and two connecting members 12. The two sets of steering mechanisms 11 are respectively arranged on both sides of the clothes dryer. The steering mechanism 11 is provided with a rotating shaft 1113. One end of each of the two connecting members 12 is connected to the driving device 20, bypasses the steering mechanism 11 respectively, and the other end is connected to the clothes drying rod assembly 30. The driving device 20 drives the connecting member 12 to pull the clothes drying rod assembly 30 to lift and lower. The connecting member 12 is in a strip shape or a chain shape, and can be bent in its length direction, but is not easily deformed in the axial direction of the rotating shaft 1113. In this way, it can drive the clothes drying rod assembly 30 to lift and lower, and at the same time limit the movement of the clothes drying rod assembly 30 in the axial direction of the rotating shaft 1113.

[0031] For the lifting device 10 provided by the embodiment of the present application, when the clothes drying rod assembly 30 located below the clothes dryer is affected by the wind direction perpendicular to the length direction of the clothes drying rod assembly 30, since the connecting member 12 is not easily deformed in its width direction, it is not easily blown by the wind and deformed, resulting in a large swing of the clothes drying rod assembly 30. Compared with the traditional steel wire rope structure, the strip-shaped or chain-shaped connecting member 12 provided by the embodiment of the present application can be more stable because it limits the swing in the direction perpendicular to the length direction of the clothes drying rod assembly 30, thereby improving the service life of the connecting member 12.

[0032] Further, in some embodiments, the steering mechanism 11 includes a pulley assembly, and the connecting member 12 is movably connected to the pulley assembly to perform a movement turn in the movement plane to realize the lifting and lowering of the clothes drying rod assembly 30.

[0033] Further, the pulley assembly includes a side pulley group 111 arranged near the end of the clothes dryer. The connecting member 12 is slidably connected or drivingly connected to the side pulley group 111, and turns around the rotating shaft 1113 to drive the clothes drying rod assembly 30 to lift and lower.

[0034] Specifically, the side pulley group 111 includes a side pulley frame 1111 and side pulleys 1112 disposed inside the side pulley frame 1111. The side pulley frame 1111 is provided with two side walls, and both ends of a rotating shaft 1113 are respectively connected to the two side walls. The side pulleys 1112 are sleeved on the rotating shaft 1113 and located between the two side walls. The connecting member 12 is driven by a driving device 20 to turn and rise or fall around the side pulleys 1112.

[0035] Furthermore, the pulley assembly further includes multiple groups of intermediate pulley groups 112 disposed at intervals between the driving device 20 and the side pulley group 111. The connecting member 12 passes around the multiple groups of intermediate pulley groups 112 for movement turning, so as to wind and store the connecting member 12 between the intermediate pulley groups 112, thereby solving the problem that the driving device 20 does not have enough winding space to effectively wind and store the belt-shaped or chain-shaped connecting member 12 due to its large volume.

[0036] Specifically, the intermediate pulley group 112 includes an intermediate pulley frame and intermediate pulleys 1120 disposed on the intermediate pulley frame. The intermediate pulleys 1120 are vertically connected to the intermediate pulley frame along their central axes. The connecting member 12 is driven by the driving device 20 to turn around the intermediate pulleys 1120 to achieve winding and storage.

[0037] In some embodiments, the intermediate pulley groups 112 are arranged at intervals and displaced vertically. The connecting member 12 respectively bypasses multiple intermediate pulleys 1120 along a transverse wavy track to achieve winding and storage between the intermediate pulley groups 112. Please refer to Figure 3 , in some other embodiments, the intermediate pulley groups 112 are arranged at intervals and displaced horizontally. The connecting member 12 respectively bypasses multiple intermediate pulleys 1120 along a longitudinal wavy track to achieve winding and storage between the intermediate pulley groups 112.

[0038] It can be understood that in some other embodiments, the connecting member 12 can also be wound between the intermediate pulley groups 112 along a spiral movement track, and this is not limited thereto.

[0039] Please refer to Figures 1-3 , furthermore, the steering mechanism 11 further includes a box body 113 provided with several tracks 1130 inside. The intermediate pulley groups 112 are arranged at intervals at both ends of the tracks 1130. The connecting member 12 bypasses one intermediate pulley group 112 and turns from one track 1130 to the other track 1130, so as to prevent the connecting member 12 from becoming loose due to jamming during the winding process inside the steering mechanism 11, and to prevent adjacent two sections of the connecting member 12 from interfering with each other.

[0040] Preferably, the track 1130 is arranged along the length direction of the clothes drying machine, so that the running track of the connecting member 12 between the middle pulley groups 112 is longitudinally wavy. In this setting, when the connecting member 12 is instantaneously relaxed and sags due to gravity, the independent track 1130 can support and isolate the connecting member 12, so as to avoid situations such as jamming caused by gravity contact between two adjacent sections of the connecting member 12, thereby ensuring the smooth operation of the lifting device 10.

[0041] Please refer to Figure 4 , further, in some embodiments, the connecting member 12 can be a chain, and the chain includes a pin shaft 121 and two chain link groups 122 rotatably connected to both ends of the pin shaft 121. The pin shaft 121 is arranged parallel to the rotating shaft 1113, so as to limit the deformation of the chain in its width direction, thereby resisting the cross wind on the axis of the rotating shaft 1113. The chain link group 122 includes two layers of chain links 1220 arranged in a staggered and overlapping manner. The two staggered and overlapping chain links 1220 are connected by the pin shaft 121. Both ends of a chain link 1220 of one layer are simultaneously rotatably connected to two adjacent chain links 1220 of the other layer through the pin shaft 121, so that two adjacent chain links 1220 can move towards each other around two adjacent pin shafts 121 respectively to realize the movement steering.

[0042] Specifically, the chain link group 122 is provided with a first chain link layer and a second chain link layer. The first chain link layer includes a number of adjacent first chain links, and the second chain link layer includes a number of adjacent second chain links. The first chain links and the second chain links are arranged in a staggered and overlapping manner. Both ends of the first chain link are respectively rotatably connected to two adjacent second chain links through the pin shaft 121. During the steering process, the two second chain links rotate around the pin shaft 121 respectively to form an included angle and gradually become smaller. After the steering is completed, the included angle slowly becomes larger until the two second chain links are in a straight line. Preferably, the first chain links and the second chain links have the same shape and size.

[0043] Please refer to Figure 3 , in this setting, the side pulley 1112 is a toothed sprocket engaged with the chain. The sprocket is sleeved on the rotating shaft 1113. The chain can maintain the smoothness and accuracy of the motion state through meshing with the sprocket, further improving the stability of the clothes drying rod assembly 30. It can be understood that the middle pulley 1120 around which the chain passes can also be set as a toothed sprocket engaged with the chain to improve the running stability of the chain.

[0044] Please refer to Figures 4-6 , further, in this setting, a protruding guiding rib position 1134 is arranged on the inner wall of the track 1130 along the moving direction of the chain; the guiding rib position 1134 is clamped between the two chain link groups 122 to further ensure the running stability of the chain inside the track 1130.

[0045] Further, in some embodiments, the two ends of adjacent link plates 1220 that are close to each other abut against each other on one side in the length direction of the chain. The abutting point and the two pin shafts 121 form a stable triangular force structure, thereby restricting the adjacent two link plates 1220 from rotating around the pin shafts 121 towards this side respectively. On the other side of the two ends of the adjacent link plates 1220 that are close to each other, a gradually separating plane or curved surface is provided, so that the adjacent two link plates 1220 can only rotate around the two pin shafts 121 towards this side respectively, so that the chain can be bent to realize the unilateral turning of the chain, thereby restricting the movement of the link plates 1220 in the width direction, so as to further restrict the chain. When the external air flow blows towards the clothes parallel to the length direction of the drying rod assembly 30, the swinging amplitude of the chain can be greatly reduced, and the stability of the lifting device 10 can be further improved.

[0046] Please refer to Figure 4 , in this embodiment, taking the plane formed by the axes of the pin shafts 121 at the upper and lower ends of the link plate 1220 as the central plane, the two ends on one side of the central plane are respectively a convex first arc surface 1221 and a concave second arc surface 1222. The first arc surface 1221 and the second arc surface 1222 of the adjacent two link plates 1220 that are close to each other can be fitted and abutted, so that the two adjacent chains cannot rotate along the pin shaft 121 towards this side. The two ends on the other side of the center line are respectively a convex third arc surface 1223 and a concave fourth arc surface 1224. The third arc surface 1223 and the fourth arc surface 1224 are arranged at a certain distance, and the distance between them is larger the farther away from the center line, so that the two adjacent chains rotate around the two adjacent pin shafts 121 towards this side respectively to realize the unilateral winding of the chain.

[0047] Further, in some other embodiments, the connecting member 12 is strip-shaped, such as a steel strip, a tape measure, etc. These strip-shaped connecting members 12 can be bent in the length direction and can remain stable in the width direction. When affected by a crosswind parallel to its width direction, they will not swing greatly, so as to avoid the situation that the drying rod assembly 30 pulled by its end shakes and causes the clothes to fall. One end of the connecting member 12 away from the drying rod assembly 30 bypasses the side pulley 1112 and is sequentially bypassed through a plurality of intermediate pulleys 1120 by the traction member 13 and is wound and stored between the intermediate pulley groups 112.

[0048] Please refer to Figures 1-3, Further, a driving device 20 is provided at the end of the connecting member 12 with a traction member 13 that is easily wound, such as a wire rope. By winding the traction member 13 through the driving device 20, the overall connecting member 12 is driven to displace, thereby driving the lifting and lowering of the lower drying rod assembly 30. In this setting method, the length of the traction member 13 is at least greater than the maximum lifting height of the drying rod assembly 30, so that the drying rod assembly 30 can run to its lowest operating height when the traction member 13 is in a state of not being wound by the driving device 20. In this way, the driving device 20 only needs to wind the traction member 13 with a smaller size to drive the lifting and lowering of the drying rod assembly 30, without adding a storage structure for winding the larger-sized connecting member 12, so as to simplify the structure of the driving device 20.

[0049] Please refer to Figure 2 and Figure 6 , in this setting method, a wire groove 1124 is provided on the middle pulley 1120 around which the traction member 13 passes, to prevent the traction member 13 from jumping wires and causing the lifting device 10 to get stuck. In addition, a cutout 1135 for the traction member 13 to clear the air can be cut on the upper wall surface or the lower wall surface of the track 1130, to reduce the friction between the traction member 13 and the wall surface of the track 1130 and improve the service life of the traction member 13.

[0050] Please refer to Figures 1-6 , as an example, in this embodiment, the connecting member 12 is a one-sided turning chain, the traction member 13 is a wire rope, one end of the wire rope is wound around the driving device 20, the other end is connected to the chain through a rope end, wound inside the middle pulley group 112, and its end passes through the side pulley group 111 and is connected to the lower drying rod assembly 30.

[0051] Specifically, the middle pulley group 112 includes a first pulley 1121 and a third pulley 1123 provided at one end of the box body 113 close to the driving device 20, and a second pulley 1122 provided at one end of the box body 113 close to the side pulley group 111. The box body 113 is correspondingly provided with three independent tracks 1130 from top to bottom, which are respectively defined as a first track 1131, a second track 1132, and a third track 1133. Among them, the chain bypasses the side pulley 1112 and the first pulley 1121 and moves within the first track 1131 and the second track 1132, and the wire rope can bypass the first pulley 1121, the second pulley 1122, and the third pulley 1123 and move within all the tracks 1130. Among them, the first pulley 1121 and the second pulley 1122 are provided with wire grooves 1124 to facilitate the turning of the wire rope and prevent the situation of wire rope jumping; the third pulley 1123 is provided at the sliding end of the wire rope to isolate the wire rope and the chain and prevent the situation of the lifting device 10 being stuck due to the wire rope being caught in the chain.

[0052] Preferably, in this setting mode, the length of the box body 113 should at least meet the requirement that when the drying rod assembly 30 is in the storage state, the chain can be wound and stored in the first track 1131 and the second track 1132.

[0053] An embodiment of the present application further provides an electric drying rack, which includes a main machine housing 40, a driving device 20, a drying rod assembly 30, and a lifting device 10 connecting the driving device 20 and the drying rod assembly 30. The main machine housing 40 is provided with a drying rod slot 41, and the driving device 20 and the lifting device 10 are fixedly connected to the bottom of the drying rod slot 41; the drying rod assembly 30 is arranged below the main machine housing 40, and is driven by the driving device 20 to drive the lifting device 10 to pull it up and down, and is stored in the drying rod slot 41.

[0054] Preferably, the lifting device 10 is symmetrically arranged at both ends of the driving device 20. The driving device 20 is provided with a double-end motor. The two connecting pieces 12 are respectively connected to both ends of the double-end motor, and their ends bypass the steering mechanism 11 and are connected to the drying rod assembly 30 below. The movement of the connecting piece 12 is restricted by the steering mechanism 11, and the connecting piece 12 is wound and stored in the steering mechanism 11, so that the connecting piece can stably pull the drying rod assembly 30 up and down, and at the same time ensure that the drying rod assembly 30 remains stable in the drying state to avoid wind sway.

[0055] Compared with the prior art, the beneficial effects of the embodiment of the present application are as follows:

[0056] (1) A belt-shaped or chain-shaped connecting piece is used to pull the drying rod assembly. The connecting piece can be bent in its length direction and is not easily deformed in its width direction, so it can stably drive the drying rod assembly to rise and fall. At the same time, when there is a cross wind perpendicular to the length direction of the drying rod assembly, the connecting piece can limit the large swing of the drying rod assembly, making the connecting piece more stable, thereby improving the service life of the connecting piece;

[0057] (2) The lifting device uses a chain with three-sided constraints, which can only rotate and wind unidirectionally, further improving its anti-wind sway effect;

[0058] (3) By setting a steering mechanism to steer and store the connecting piece and the traction piece, the space utilization rate is improved;

[0059] (4) By setting a box body with multiple layers of tracks to restrict the movement of the connecting piece, it is possible to avoid interference between the connecting piece and the traction piece that are close to each other, and at the same time avoid the problem of the traction piece jumping the line.

[0060] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to cover these modifications and variations.
