Double-layer roller for drying machine

Abstract

The double-layer rotary drum comprises an inner drum and an outer drum which are coaxially arranged, the inner wall of the outer drum is attached to the outer wall of the inner drum, the outer drum rotates relative to the inner drum, at least one first strip-shaped hole extending in the circumferential direction is formed in the inner drum, and the first strip-shaped hole is communicated with the first strip-shaped hole. Second strip-shaped holes matched with the first strip-shaped holes in a one-to-one mode are formed in the outer cylinder and extend in the circumferential direction of the outer cylinder. According to the roller, by rotating the outer roller relative to the inner roller or rotating the inner roller relative to the outer roller, the intersection area between the first strip-shaped holes and the second strip-shaped holes is adjusted, so that the effect of changing the sizes of the holes in the surface of the roller is achieved, and the roller is suitable for drying clothes with small falling pieces or not. If so, the holes in the surface of the roller can be reduced; and if not, the holes in the surface of the roller can be enlarged, the overall function is complete, and practicability is high.

Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of roller, more specifically, it relates to a kind of double-layer roller for dryer. BACKGROUND

[0002] The roller configured inside the dryer on market is mostly single-layer structure, and the size of hole on its surface is fixed and cannot be adjusted. Too small hole is not conducive to hot air convection, and too large hole is easy to jam the falling piece on clothes. The overall effect is not good. Accordingly, the utility model provides a double-layer roller for dryer. SUMMARY

[0003] The utility model aims at overcoming the deficiencies in the prior art, and provides a double-layer roller for dryer.

[0004] To solve the above technical problems, the utility model aims at realizing as follows: the utility model relates to a kind of double-layer roller for dryer, which comprises an inner cylinder and an outer cylinder arranged coaxially, the inner wall of the outer cylinder is attached to the outer wall of the inner cylinder, the outer cylinder rotates relative to the inner cylinder, at least one first strip-shaped hole is formed on the inner cylinder and extends in the circumferential direction, and a second strip-shaped hole is formed on the outer cylinder and matches the first strip-shaped hole, and the second strip-shaped hole extends in the circumferential direction of the outer cylinder.

[0005] The utility model is further provided as follows: the extension angle of the first strip-shaped hole is equal to the extension angle of the second strip-shaped hole.

[0006] The utility model is further provided as follows: the first strip-shaped hole and the second strip-shaped hole are of the same shape and have the same size.

[0007] In summary, the utility model has the following advantages: the double-layer roller for dryer disclosed by the utility model adjusts the intersection area between the first strip-shaped hole and the second strip-shaped hole by rotating the outer cylinder relative to the inner cylinder or rotating the inner cylinder relative to the outer cylinder, thereby changing the size of the hole on the surface of the roller, and the dryer can be used to dry clothes with or without small falling pieces. If there are small falling pieces, the size of the hole on the surface of the roller can be reduced, and if there are no small falling pieces, the size of the hole on the surface of the roller can be increased. The overall function is perfect, and the utility model has strong practicality. BRIEF DESCRIPTION OF DRAWINGS

[0010] In order to make the technical scheme of the present application better understood by those skilled in the art, the preferred embodiments of the present application will be described below in conjunction with specific embodiments, but it should be understood that these descriptions are only intended to further illustrate the features and advantages of the present application, and not to limit the patent claims of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0011] The present application will be further illustrated below in conjunction with the drawings and preferred embodiments.

[0012] Embodiment 1

[0013] Referring to Figure 1 and Figure 2 , the present embodiment relates to a double-layered drum for a dryer, which comprises an inner drum 1 and an outer drum 2 arranged coaxially, the inner wall of the outer drum 2 is attached to the outer wall of the inner drum 1, the outer drum 2 rotates relative to the inner drum 1, at least one first strip-shaped hole 3 is formed on the inner drum 1 and extends along the circumference, and a second strip-shaped hole 4 is formed on the outer drum 2 and matches the first strip-shaped hole one by one, and the second strip-shaped hole 4 extends along the circumference of the outer drum 2.

[0014] Further, the extension angle of the first strip-shaped hole 3 is equal to the extension angle of the second strip-shaped hole 4.

[0015] Further, the first strip-shaped hole 3 and the second strip-shaped hole 4 are the same in shape and equal in size.

[0016] Further, the outer drum 2 is provided with a locking structure for limiting the rotation of the outer drum 2 relative to the inner drum 1; the locking structure comprises a locking screw which abuts against the inner drum 1 and is threadedly connected to the outer drum 2.

[0017] The double-layered drum for a dryer relates to the present application, which rotates the outer drum relative to the inner drum or rotates the inner drum relative to the outer drum to adjust the intersection area between the first strip-shaped hole and the second strip-shaped hole, so as to change the size of the holes on the surface of the drum, so as to adapt to the drying use of clothes with or without small falling pieces. If there are, the size of the holes on the surface of the drum can be reduced; if there are not, the size of the holes on the surface of the drum can be increased, the overall function is perfect, and the practicability is strong.

[0018] Unless otherwise defined, all terms used in the disclosure, such as "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, are to be interpreted, unless otherwise indicated, in the case in which the actual shown orientation or position relationship is based, only for the convenience of describing the present application and simplifying the description, and therefore the orientation or position relationship described in the present application is only used for exemplary description, and cannot be understood as a limitation on the present patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood in conjunction with the embodiments and according to the specific circumstances.
