[0031] With reference to Figures 1 to 6 The electric heating towel rack of the utility model embodiment, including frame body 100, heat conduction crossbeam 200 and heating strip 300. Heat conduction crossbeam 200 is set up in frame body 100, and heat conduction crossbeam 200 includes main pipe body 210 and inner tube body 220, and main pipe body 210 and inner tube body 220 are all extended along the length direction of heat conduction crossbeam 200, and main pipe body 210 is provided with accommodating hole 211 along the length direction of heat conduction crossbeam 200, and inner tube body 220 is set up in main pipe body 210 and is located in accommodating hole 211, and the outer peripheral wall of inner tube body 220 is connected with the hole wall of accommodating hole 211, or the outer peripheral wall of inner tube body 220 is connected with the hole wall of accommodating hole 211 through heat conduction connecting part 230, and inner tube body 220 is provided with mounting hole 221 along the length direction of heat conduction crossbeam 200;Heating strip 300 is extended along the length direction of heat conduction crossbeam 200, and heating strip 300 is set up in inner tube body 220 and is located in mounting hole 221, and when heating strip 300 heats, the outer peripheral wall of heating strip 300 is adapted with the hole wall of mounting hole 221 and surface contact.

[0032] When heating strip 300 heats, the outer peripheral wall is adapted with the hole wall of mounting hole 221 of the inner tube body 220 of heat conduction crossbeam 200 and surface contact, and inner tube body 220 is directly connected with main pipe body 210 or is connected through heat conduction connecting part 230, and the contact area of heating strip 300 and heat conduction crossbeam 200 is increased through inner tube body 220, and heating strip 300 mainly contacts and heat transfers through inner tube body 220 to make heat conduction crossbeam 200 warm, and the warming speed of heat conduction crossbeam 200 can be improved due to the fact that the heat conduction efficiency of solid is greater than that of air, and then the drying efficiency of electric heating towel rack is improved.

[0033] Specifically, heating strip 300 is an electric heating wire. It can be understood that, in some embodiments, heating strip 300 can also be an electric heating tube or the like.

[0034] Specifically, when heating strip 300 heats, the outer peripheral surface of heating strip 300 and the hole wall of mounting hole 221 are interference fit due to thermal expansion and cold contraction. When heating strip 300 cools, the outer peripheral surface of heating strip 300 and the hole wall of mounting hole 221 are clearance fit, or have slight clearance, facilitating the installation of heating strip 300 into mounting hole 221;As long as the outer peripheral wall of heating strip 300 can be adapted with the hole wall of mounting hole 221 and surface contact when heating strip 300 heats.

[0035] In some embodiments, the inner tube body 220 is provided with two and arranged in the length direction of the cross section of the accommodating hole 211, and each inner tube body 220 is provided with a heating strip 300. A plurality of inner tube bodies 220 are arranged in the length direction of the cross section of the accommodating hole 211, and each inner tube body 220 is provided with a heating strip 300, which further improves the heating speed and drying capacity of the heat conduction beam 200, and makes the heat conduction beam 200 have relatively uniform heating temperature in the length direction of the cross section of the accommodating hole 211, and reduces the temperature difference of the heat conduction beam 200.

[0036] In embodiments, the length direction of the heat conduction beam 200 is the left-right direction, and the inner tube body 220 is provided with two, one of which is located at the upper part of the accommodating hole 211, and the other is located at the lower part of the accommodating hole 211, and each inner tube body 220 is provided with a heating strip 300. By providing two inner tube bodies 220, one at the upper part of the accommodating hole 211 and the other at the lower part of the accommodating hole 211, the upper and lower ends of the heat conduction beam 200 can be quickly heated and have relatively uniform temperature, and the heat conduction beam 200 can be quickly heated and have relatively uniform temperature at each part by solid heat conduction, and without the need to provide too many inner tube bodies 220 and heating strips 300, the structure of the heat conduction beam 200 is simplified, and the production cost is saved.

[0037] It can be imagined that in other embodiments, the heat conduction beam 200 can also be provided with one, three, four or more inner tube bodies 220, and the number of heating strips 300 is the same as that of the inner tube bodies 220, which can be specifically selected by those skilled in the art according to actual needs.

[0038] In embodiments, the cross section of the accommodating hole 211 is strip-shaped, polygonal or circular. Specifically, in the first, second and third embodiments, the cross section of the accommodating hole 211 is strip-shaped, and the length direction of the cross section is the up-down direction. In the fourth embodiment, the cross section of the accommodating hole 211 is circular, one inner tube body 220 is located at the upper end of the accommodating hole 211, and the other inner tube body 220 is located at the lower end of the accommodating hole 211. In the fifth embodiment, the cross section of the accommodating hole 211 is rectangular, one inner tube body 220 is located at the upper end of the accommodating hole 211, and the other inner tube body 220 is located at the lower end of the accommodating hole 211. The above-mentioned accommodating hole 211 has a simple structure and is relatively easy to process.

[0039] In the first embodiment, the length direction of the heat-conducting crossbeam 200 is the left-right direction, the cross section of the accommodating hole 211 is strip-shaped and the length direction of the cross section of the accommodating hole 211 is the up-down direction, and the cross section of the main pipe body 210 is strip-shaped and the length direction of the cross section of the main pipe body 210 is the up-down direction. The outer surface of the heat-conducting crossbeam 200 within a certain range belongs to the effective drying area, the cross section of the main pipe body 210 is strip-shaped and the length direction of the cross section is the up-down direction, which is beneficial to the towel to enter the effective drying area of the heat-conducting crossbeam 200 in a larger area, and fully utilize the large-area effective drying area of the front and back sides of the heat-conducting crossbeam 200.

[0040] In the first embodiment, the outer peripheral wall of the inner pipe body 220 is spaced apart from the hole wall of the accommodating hole 211, the front and back sides of the inner pipe body 220 are connected to the hole wall of the accommodating hole 211 through the heat-conducting connecting part 230, the thickness of the heat-conducting connecting part 230 is greater than the wall thickness of the inner pipe body 220, and the thickness of the heat-conducting connecting part 230 is greater than the wall thickness of the main pipe body 210. The front and back sides of the inner pipe body 220 are connected to the main pipe body 210 through the heat-conducting connecting part 230, so that the inner pipe body 220 can heat faster to the main pipe body 210 through the heat-conducting connecting part 230; and the thickness of the heat-conducting connecting part 230 is large, which increases the heat transfer area, so that the heat of the inner pipe body 220 can be transferred to the main pipe body 210 faster, and the heating speed of the heat-conducting crossbeam 200 is improved.

[0041] It can be understood that the thickness of the heat-conducting connecting part 230 can be greater than the wall thickness of the inner pipe body 220, or the thickness of the heat-conducting connecting part 230 can be greater than the wall thickness of the main pipe body 210, both of which can improve the heat conduction efficiency between the inner pipe body 220 and the main pipe body 210.

[0042] In the first embodiment, the outer wall of the main pipe body 210 is concave to form an emptying groove 212, and the emptying groove 212 extends along the left-right direction. When the towel is hung on the heat-conducting crossbeam 200, the side of the towel close to the heat-conducting crossbeam 200 can be attached to the outer wall of the main pipe body 210, and the water vapor on the side of the towel close to the heat-conducting crossbeam 200 is not easy to be discharged. The outer wall of the main pipe body 210 forms the emptying groove 212, which facilitates the air flow between the towel and the heat-conducting crossbeam 200 through the emptying groove 212, which is beneficial to the discharge of water vapor, and after the towel is dried, the emptying groove 212 can form a fluffy space for the towel, so that the towel is more fluffy after drying.

[0043] In the first embodiment, the front and rear outer walls of the main pipe body 210 are concavely provided with the air-avoiding grooves 212, and the cross section of the air-avoiding grooves 212 is arc-shaped. Since the areas of the front and rear outer walls of the main pipe body 210 are relatively large, the air-avoiding grooves 212 arranged on the front and rear outer walls of the main pipe body 210 can form relatively large air-avoiding grooves 212, and the towels will not be embedded in the air-avoiding grooves 212 under the action of gravity, and the air flow effect and water vapor discharge effect of the air-avoiding grooves 212 are better; the cross section of the air-avoiding grooves 212 is arc-shaped, so that the processing technology of the main pipe body 210 is relatively simple, and the hand feeling is smooth.

[0044] It can be imagined that in other embodiments, the cross section of the air-avoiding grooves 212 can also be inverted trapezoidal or rectangular, and the air-avoiding grooves 212 can also be arranged on the outer walls in other directions of the main pipe body 210, and the person skilled in the art can select them according to actual needs.

[0045] In the first embodiment, the main pipe body 210, the heat-conducting connecting part 230 and the inner pipe body 220 are integrally formed. When the inner pipe body 220 is connected with the main pipe body 210 through the heat-conducting connecting part 230, the integrally formed processing mode is convenient for processing and production, and the structure is simple. Specifically, the heat-conducting cross beam 200 is processed by profile extrusion, so that the main pipe body 210, the heat-conducting connecting part 230 and the inner pipe body 220 are integrally formed.

[0046] In the second, third, fourth and fifth embodiments, the main pipe body 210 and the inner pipe body 220 are integrally formed. When the inner pipe body 220 is directly connected with the main pipe body 210, the integrally formed processing mode is convenient for processing and production, and the structure is simple. Specifically, the heat-conducting cross beam 200 is processed by profile extrusion, so that the main pipe body 210 and the inner pipe body 220 are integrally formed.

[0047] Specifically, in the second and third embodiments, the front and rear outer walls of the inner pipe body 220 are connected with the hole walls of the accommodating hole 211 of the main pipe body 210; in the fourth and fifth embodiments, the upper or lower outer wall of the inner pipe body 220 is connected with the hole wall of the accommodating hole 211 of the main pipe body 210.

[0048] In the embodiments, six heat-conducting cross beams 200 are arranged, the length direction of the heat-conducting cross beam 200 is the left-right direction, and all the heat-conducting cross beams 200 are arranged in the up-down direction. When the towel is hung, the towel can be hung on the uppermost heat-conducting cross beam 200. Since the length of the towel is relatively large, different areas of the towel that droop downward can be heated and dried by different heat-conducting cross beams 200 arranged in the up-down direction, so as to further improve the drying speed and uniformity of the towel. It can be understood that the towel can also be hung on any heat-conducting cross beam 200.

[0049] It can be imagined that in other embodiments, the number of heat-conducting crossbeams 200 can also be, for example, two, three, four or more, which can be specifically selected by those skilled in the art according to actual needs.

[0050] Specifically, both ends of the heat-conducting crossbeam 200 are connected with the frame body 100, so that the heat-conducting crossbeam 200 is relatively firm in combination with the frame body 100, and is conducive to the strong load-carrying capacity of the heat-conducting crossbeam 200.
