Description

Technical Field

[0001] The present invention belongs to the field of clothes drying structures. Background Art

[0002] The integral clothes drying structure with clothes drying arms distributed in a circumferential array can make better use of the occupied space, but also brings the following problems

[0003] (1) When idle, the clothes drying arms distributed in a circumferential array are in a horizontal radial shape, which hinders people's activity space;

[0004] (2) If the longitudinal sizes of the clothes to be dried are different, such as children's clothes, tops, shorts, etc. which belong to clothes with short longitudinal sizes; for example, dresses, adult trousers, etc. which belong to clothes with long longitudinal sizes; the clothes with short longitudinal sizes are clamped between adjacent straight clothes drying arms with too small spacing, resulting in poor ventilation and insufficient drying rate.

[0005] (3) If all the clothes to be dried are adult trousers or dresses with large longitudinal sizes, there is a problem that the lower ends of the clothes touch the ground and get dirty. Summary of the Invention

[0006] Object of the Invention: In order to overcome the deficiencies in the prior art, the present invention provides a multifunctional clothes drying device and working method. When drying clothes with various different longitudinal sizes, the clothes dried on the upwardly inclined straight clothes drying arms are staggered in the longitudinal space with the clothes dried on several horizontal straight clothes drying arms, forming a staggered distribution pattern, so as to avoid the problem of poor ventilation and insufficient drying rate caused by too small spacing between adjacent straight clothes drying arms.

[0007] Technical Solution: To achieve the above object, a multifunctional clothes drying device of the present invention includes a base. Straight clothes drying arms are distributed in a circumferential array on the outer periphery of the base. A plurality of clothes hanger hook holes are arranged along the length direction on the straight clothes drying arms. The hook of the clothes hanger can be hooked in the clothes hanger hook holes; each straight clothes drying arm can swing from the root to an upwardly inclined posture and a horizontal posture.

[0008] Further, a turntable with a horizontal axis is fixedly connected to the root of each straight clothes drying arm. The straight clothes drying arm extends along the radial direction of the turntable; the axis center of the turntable is rotatably installed on a fixed shaft through a bearing, and each straight clothes drying arm swings up and down along the corresponding fixed shaft.

[0009] Further, a shoe drying tabletop is coaxially and fixedly arranged above the base. A plurality of clothes drying arm slots extending along the radial direction are arranged in a circumferential array on the contour edge of the shoe drying tabletop.

[0010] Further, a torsion wheel is provided corresponding to the lower part of each turntable, and the torsion wheel is linked with the upper turntable through a torsion transmission rope.

[0011] Further, a rotating shaft is integrally and coaxially connected to the torsion wheel. Each rotating shaft is rotatably installed on a bearing seat. A torsion spring is arranged outside the rotating shaft. The torsion spring forms a clockwise torque on the torsion wheel, so that the torsion wheel always has a tendency to rotate clockwise. The torsion wheel is composed of a central rope winding wheel disc and side wheel discs integrally and coaxially at both ends of the central rope winding wheel disc. The outer diameter of the central rope winding wheel disc is smaller than that of the side wheel discs. It further includes a flexible torsion transmission rope. The torsion transmission rope is successively a continuous first arc segment, a straight tension segment and a second arc segment along the length direction. Arc-shaped rope grooves are arranged on the outer peripheral surfaces of the respective turntables along the contour path. The first arc segment is wound in an arc shape in the arc-shaped rope groove of the turntable, and the clockwise end of the first arc segment is fixed to the root end of the straight clothes drying arm. The second arc segment is wound in an arc shape on the outer wall of the central rope winding wheel disc, and the clockwise end of the second arc segment is fixedly connected to the outer wall of the central rope winding wheel disc through a fixing pile.

[0012] Further, the clockwise torque formed by the torsion spring on the torsion wheel is transmitted to the turntable in the form of a counterclockwise torque N1 through the torsion transmission rope. When no clothes are loaded on the straight clothes drying arm, the straight clothes drying arm swings upward along the fixed axis under the action of the counterclockwise torque N of the torsion transmission rope and is clamped into the corresponding clothes drying arm card slot, so that the end of the straight clothes drying arm is in an upwardly inclined posture.

[0013] After a clothes hanger loaded with wet clothes is hung in the clothes hanger hook hole of the straight clothes drying arm, the gravity of the straight clothes drying arm, the clothes hanger hooked on the straight clothes drying arm and the wet clothes is transmitted to the turntable in the form of a clockwise torque N2 through the straight clothes drying arm, satisfying N2 > N1. Thus, the straight clothes drying arm swings upward along the fixed axis to the horizontal position. After the straight clothes drying arm swings upward along the fixed axis to the horizontal position, the lower surface of the straight clothes drying arm contacts the upper contour of the base, making the straight clothes drying arm unable to swing downward continuously.

[0014] Further, a horizontal fixed disk is fixedly arranged in the base. The ends of the respective fixed shafts are fixedly connected to the horizontal fixed disk through fixed shaft brackets. A disk-shaped movable base is coaxially arranged on the upper side of the horizontal fixed disk. Each bearing seat is fixed on the movable base. The up-and-down displacement of the movable base can synchronize the up-and-down displacement of each torsion wheel. The torsion wheel can move upward to be tangent to the corresponding turntable above, so that the outer peripheral friction surface one of the turntable is closely tangent to the outer peripheral friction surface two of the side wheel disc.

[0015] Further, a pair of upwardly extending guide columns are fixedly connected to the horizontal fixed disk. The shoe drying desktop is supported at the upper ends of the guide columns. The guide columns movably pass through the guide holes on the movable base. A lead screw nut is fixed at the center of the movable base. It further includes a transmission lead screw that cooperates with the lead screw nut. A lead screw driving motor is fixedly installed below the horizontal fixed disk, and the lead screw driving motor is drivingly connected to the transmission lead screw.

[0016] Furthermore, a method for using a multifunctional clothes drying device:

[0017] In the idle state:

[0018] When in the idle state, each linear clothes drying arm swings upward along the fixed axis under the action of the counterclockwise torque N1 of its respective torque transmission rope and is snapped into the corresponding clothes drying arm slot, so that the ends of all the linear clothes drying arms are in an upward posture; the ends of all the linear clothes drying arms are automatically in an upward posture under the action of the torsion spring, and the higher end of the linear clothes drying arm in the upward posture is higher than the height of a normal person, maximizing the space for people's activities without interference.

[0019] If the longitudinal dimensions of the clothes to be dried are of different lengths;

[0020] Make the clothes dried on several upward linear clothes drying arms and the clothes dried on several horizontal linear clothes drying arms staggered in the longitudinal space, forming a staggered distribution pattern, so as to avoid the problem of poor ventilation and insufficient drying rate caused by too small a distance between adjacent two linear clothes drying arms.

[0021] If all the clothes to be dried are clothes with large longitudinal dimensions, when all the linear clothes drying arms are in the posture with the ends upward, the movable base is raised by the lead screw drive motor until the clockwise rotation of all the turntables is locked, so that all the linear clothes drying arms are fixed in the upward state, which is convenient for drying more adult trousers or dresses.

[0022] Beneficial effects:

[0023] (1) When idle, all the linear clothes drying arms do not carry any clothes. Each linear clothes drying arm swings upward along the fixed axis under the action of the counterclockwise torque N1 of its respective torque transmission rope and is snapped into the corresponding clothes drying arm slot, so that the ends of all the linear clothes drying arms are in an upward posture; the ends of all the linear clothes drying arms are automatically in an upward posture under the action of the torsion spring, and the higher end of the linear clothes drying arm in the upward posture is higher than the height of a normal person, maximizing the space for people's activities without interference.

[0024] (2) If the longitudinal dimensions of the clothes to be dried are of different lengths, such as children's clothes, tops, shorts, etc. which belong to clothes with short longitudinal dimensions; for example, dresses, adult trousers, etc. which belong to clothes with long longitudinal dimensions; the clothes dried on several upward linear clothes drying arms and the clothes dried on several horizontal linear clothes drying arms are staggered in the longitudinal space, forming a staggered distribution pattern, so as to avoid the problem of poor ventilation and insufficient drying rate caused by too small a distance between adjacent two linear clothes drying arms.

[0025] (3) If all the clothes to be dried are adult pants or dresses, which have a large longitudinal dimension, and all the straight drying arms are in an upward-tilted posture at the ends, the movable base is raised by the lead screw drive motor until the clockwise rotation of all the turntables is locked, so that all the straight drying arms are fixed in the upward-tilted state, facilitating the drying of more adult pants or dresses.

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] As shown in FIG Figures 1 to 9 a multifunctional clothes drying device, as Figure 1 including a base 11, a shoe drying tabletop 7 is fixedly arranged coaxially above the base 11, straight drying arms 6 are distributed in a circumferential array on the outer periphery of the base 11, a plurality of clothes hanger hook holes 10 are arranged along the length direction on the straight drying arms 6, and the hooks of the clothes hanger can be hooked in the clothes hanger hook holes 10; each straight drying arm 6 can swing from the root to an upward-tilted posture and a horizontal posture.

[0037] When the straight clothes drying arm 6 is in an upward posture, it can be used to hook clothes with a large longitudinal dimension, so that the clothes are not easily in contact with the ground; when the straight clothes drying arm 6 is in a horizontal posture, it is used to hook clothes with a smaller longitudinal dimension, and when the straight clothes drying arm 6 is in a horizontal posture, the horizontal dimension between two adjacent clothes hanger hook holes 10 is the largest, ensuring the distance between clothes and improving the ventilation effect between two adjacent clothes; if a number of upward straight clothes drying arms 6.2 and a number of horizontal straight clothes drying arms 6.1 are staggered in the longitudinal space as Figure 2 shown, the clothes dried on a number of upward straight clothes drying arms 6.2 and the clothes dried on a number of horizontal straight clothes drying arms 6.1 are staggered in the longitudinal space, forming a staggered distribution pattern, avoiding the problem of poor ventilation and insufficient drying rate caused by too small a distance between two adjacent straight clothes drying arms 6; the specific structure for realizing the above is as follows:

[0038] As Figure 5 At the root of each straight clothes drying arm 6, a turntable 1 with a horizontal axis is fixedly connected, and the straight clothes drying arm 6 extends along the radial direction of the turntable 1; the axis center of the turntable 1 is rotatably installed on the fixed shaft 22 through a bearing, and each straight clothes drying arm 6 swings up and down along the corresponding fixed shaft 22; an arc rope groove 1.2 is arranged on the outer peripheral surface 11 of the turntable 1 along the contour path;

[0039] As Figure 3 , the base 11 is a cylindrical box structure, and a horizontal fixed disk 16 is fixedly arranged inside the box structure of the base 11, and the ends of each fixed shaft 22 are fixedly connected to the horizontal fixed disk 16 through a fixed shaft bracket 19; as Figure 2 and 3 A number of clothes drying arm slots 8 extending along the radial direction are arranged in a circular array on the contour edge of the shoe drying desktop 7;

[0040] As Figure 5 , a torsion wheel 2 is arranged corresponding to the lower part of each turntable 1, and the torsion wheel 2 is linked with the upper turntable 1 through a torsion transmission rope 3. A rotating shaft 21 is integrally connected coaxially on the torsion wheel 2, and both ends of each rotating shaft 21 are rotatably installed on a bearing seat 18 through a bearing, as Figure 6 , a torsion spring 20 is arranged outside the rotating shaft 21, and both ends of the torsion spring 20 are respectively fixedly connected to the torsion wheel 2 and the bearing seat 18. The torsion spring 20 forms a clockwise torque on the torsion wheel 2, so that the torsion wheel 2 always has a tendency to rotate clockwise; as Figure 7 and 8 , the torsion wheel 2 is composed of a central winding rope wheel disc 2.1 and side wheel discs 2.2 integrally coaxially connected to both ends of the central winding rope wheel disc 2.1; the outer diameter of the central winding rope wheel disc 2.1 is smaller than the outer diameter of the side wheel discs 2.2;

[0041] As Figure 7 、 9; It further includes a flexible torque transmission rope 3. Along the length direction, the torque transmission rope 3 is successively a continuous first arc segment 3.1, a straight tension segment 3.2, and a second arc segment 3.3. The first arc segment 3.1 is wound in an arc shape in the arc rope groove 1.2 of the turntable 1, and the clockwise end of the first arc segment 3.1 is fixed at the root end 5 of the straight clothes drying arm 6. The second arc segment 3.3 is wound in an arc shape on the outer wall of the central rope winding wheel disc 2.1, and the clockwise end of the second arc segment 3.3 is fixedly connected to the outer wall of the central rope winding wheel disc 2.1 through a fixing pile 4. The clockwise torque formed by the torsion spring 20 on the torsion wheel 2 is transmitted to the turntable 1 in a counterclockwise direction torque N1 through the torque transmission rope 3. When no clothes are loaded on the straight clothes drying arm 6, the straight clothes drying arm 6 swings upward along the fixed shaft 22 under the action of the counterclockwise torque N1 of the torque transmission rope 3 and is snapped into the corresponding clothes drying arm card slot 8, so that the end of the straight clothes drying arm 6 is in an upwardly inclined posture. After a clothes hanger loaded with wet clothes is hung in the clothes hanger hook hole 10 of the straight clothes drying arm 6, the gravity of the straight clothes drying arm 6, the clothes hanger hooked on the straight clothes drying arm 6, and the wet clothes is transmitted to the turntable 1 in a clockwise torque N2 through the straight clothes drying arm 6, satisfying N2 > N1, so that the straight clothes drying arm 6 swings upward along the fixed shaft 22 to the horizontal. After the straight clothes drying arm 6 swings upward along the fixed shaft 22 to the horizontal, the lower surface of the straight clothes drying arm 6 contacts the upper contour 11.1 of the base 11, making the straight clothes drying arm 6 unable to swing downward continuously;

[0042] A disc-shaped movable base 9 is coaxially arranged on the upper side of the horizontal fixed disc 16, and each bearing seat 18 is fixed on the movable base 9. The up and down displacement of the movable base 9 can synchronize the up and down displacement of each torsion wheel 2. The torsion wheel 2 can be displaced upward to be tangent to the corresponding turntable 1 above, so that the outer peripheral friction surface one 1.1 of the turntable 1 is closely tangent to the outer peripheral friction surface two 2.3 of the side wheel disc 2.2, as Figure 9 ; During the upward displacement of the central rope winding wheel disc 2.1, under the clockwise torsion of the torsion spring 20, the torsion wheel 2 rotates clockwise adaptively, making the second arc segment 3.3 gradually longer, the straight tension segment 3.2 gradually shorter and always in a tensioned state, and the length of the first arc segment 3.1 remains unchanged;

[0043] As Figure 3 A pair of upwardly extending guide columns 12 are fixedly connected to the horizontal fixed disc 16, and the shoe drying tabletop 7 is supported on the upper ends of the guide columns 12. The guide columns 12 pass through the guide holes 17 on the movable base 9 movably. A lead screw nut 14 is fixed at the axis center of the movable base 9, and it further includes a transmission lead screw 15 that cooperates with the lead screw nut 14. A lead screw drive motor 13 is fixedly installed below the horizontal fixed disc 16, and the lead screw drive motor 13 is drivingly connected to the transmission lead screw 15;

[0044] Usage process and working principle:

[0045] When idle, all the straight clothes drying arms 6 are not loaded with any clothes. Under the action of the counterclockwise torque N1 transmitted by their respective torque transmission ropes 3, each straight clothes drying arm 6 swings upward along the fixed shaft 22 and is snapped into the corresponding clothes drying arm slots 8, so that the ends of all the straight clothes drying arms 6 are in an upward posture; the ends of all the straight clothes drying arms 6 are automatically in an upward posture under the action of the torsion spring. The higher end of the straight clothes drying arm 6 in the upward posture is higher than the height of a normal person, so as to minimize the interference with people's activity space.

[0046] Usage process:

[0047] In the initial state, all the straight clothes drying arms 6 are not loaded with any clothes. Under the action of the counterclockwise torque N1 transmitted by their respective torque transmission ropes 3, each straight clothes drying arm 6 swings upward along the fixed shaft 22 and is snapped into the corresponding clothes drying arm slots 8, so that the ends of all the straight clothes drying arms 6 are in an upward posture; as Figure 1 ; If the longitudinal dimensions of the clothes to be dried are long and short, such as children's clothes, tops, shorts, etc. which belong to clothes with short longitudinal dimensions; for example, dresses, adult long trousers, etc. which belong to clothes with long longitudinal dimensions;

[0048] Select half of the total number of straight clothes drying arms 6. The straight clothes drying arms 6 in this half are arranged in a circular array. Therefore, among the selected half of the straight clothes drying arms 6, there is an unselected straight clothes drying arm 6 between any two adjacent straight clothes drying arms 6;

[0049] Hang the hangers loaded with wet clothes with small longitudinal dimensions on the respective hanger hook holes 10 of the selected straight clothes drying arms 6. The total weight of the straight clothes drying arms 6 with the wet clothes hung on them increases significantly. The gravity of the straight clothes drying arms 6, the hangers hooked on the straight clothes drying arms 6 and the wet clothes is transmitted to the turntable 1 in the form of a clockwise torque N2 through the straight clothes drying arms 6, satisfying N2 > N1, so that all the selected straight clothes drying arms 6 swing upward along the fixed shaft 22 to the horizontal; the unselected straight clothes drying arms 6 still remain in the upward posture;

[0050] As Figure 2 and 4 , at this time, the straight clothes drying arms 6 that have become horizontal are denoted as horizontal straight clothes drying arms 6.1, and the straight clothes drying arms 6 that are not selected and still remain in the upward posture are denoted as upward straight clothes drying arms 6.2; at this time, there is a horizontal straight clothes drying arm 6.1 between any two adjacent upward straight clothes drying arms 6.2, so that several upward straight clothes drying arms 6.2 and several horizontal straight clothes drying arms 6.1 are staggered in the longitudinal space; as Figure 2 ;

[0051] At this time, the lead screw driving motor 13 is controlled. Driven by the lead screw, the movable base 9 slowly rises, so that all the torsion wheels 2 rise synchronously. During the slow rising process of the torsion wheels 2, under the clockwise torsion of the torsion spring 20, all the torsion wheels 2 adaptively rotate clockwise, making the second arc segment 3.3 gradually longer and the straight tension segment 3.2 gradually shorter while always being in a tension and force transmission state, so that the upward straight clothes drying arms 6.2 do not swing downward. Furthermore, the length of the first arc segment 3.1 remains unchanged, and thus the postures of all the straight clothes drying arms 6 do not change; as the torsion wheels 2 continue to rise until each torsion wheel 2 moves upward to be tangent to the corresponding turntable 1 above, so that the outer peripheral friction surface one 1.1 of each turntable 1 is closely tangent to the outer peripheral friction surface two 2.3 of the side wheel disc 2.2 (the surfaces of the outer peripheral friction surface one 1.1 and the outer peripheral friction surface two 2.3 are both made of anti-slip patterns and anti-slip materials with increased friction); the relationship between each turntable 1 and the corresponding torsion wheel 2 changes from the original separated state to a closely matched rolling fit relationship. Due to the close fit relationship and the material with high friction performance, the tangency between the outer peripheral friction surface one 1.1 of the turntable 1 and the outer peripheral friction surface two 2.3 of the side wheel disc 2.2 does not slip;

[0052] Since the outer diameter of the central rope winding wheel disc 2.1 is smaller than the outer diameter of the side wheel disc 2.2, when the turntable 1 rotates clockwise and the friction force between the outer peripheral friction surface one 1.1 of the turntable 1 and the outer peripheral friction surface two 2.3 of the side wheel disc 2.2 is transmitted to the torsion wheel 2, it will be subject to the rigid resistance of the torsion transmission rope 3. Therefore, the clockwise rotation of the turntable 1 enters the locked state. Therefore, as long as there is no slippage between the outer peripheral friction surface one 1.1 of the turntable 1 and the outer peripheral friction surface two 2.3 of the side wheel disc 2.2, each turntable 1 will not rotate clockwise under the action of external force;

[0053] At this time, hang clothes hangers loaded with wet clothes with large longitudinal dimensions in each clothes hanger hook hole 10 of each upward straight clothes drying arm 6.2. Although the total weight of the straight clothes drying arms 6 with the wet clothes hung on them increases significantly, at this time, the clockwise directions of all the turntables 1 are in the locked state. Therefore, even if each upward straight clothes drying arm 6.2 is hung with wet clothes, it will not make a downward swing movement;

[0054] At this time, the clothes dried on several upward straight clothes drying arms 6.2 and the clothes dried on several horizontal straight clothes drying arms 6.1 are staggered in the longitudinal space, forming a staggered distribution pattern, avoiding the problem of poor ventilation and insufficient drying rate caused by too small a distance between adjacent two straight clothes drying arms 6;

[0055] If all the clothes to be dried are adult trousers with large longitudinal dimensions, all the straight drying arms 6 cannot swing down to the horizontal. Therefore, in the initial state, when all the straight drying arms 6 are in the posture of upwardly curved ends, the movable base 9 is raised by the lead screw drive motor 13 until all the turntables 1 are locked from rotating clockwise, so that all the straight drying arms 6 are fixed in the upwardly curved state, facilitating the drying of more clothes.

[0056] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
