Benefits of technology

[0008] The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a heating device, which emits far infrared rays when producing heat and, which has the advantages of high thermal efficiency, low electromagnetic wave, ease of fabrication, and recyclable materials.

Problems solved by technology

The aforesaid prior art designs do not have a high thermal efficiency because they do not use quarts glass tubes or ceramic tubes for producing heat.

Embodiment Construction

[0012] Referring to FIG. 1, a heating device in accordance with the present invention can be used in a hair dryer, copy machine, scanner, laser printer, or the like. The heating device is comprised of an electric heating unit 10 and an air delivery unit 30.

[0013] The electric heating unit 10 is comprised of a carrier 11, a plurality of heating tubes 12, and a voltage reducing line 17. The carrier 11 is made out of an electrically insulative material, for example, plastics, having a conical profile. The two distal ends of the carrier 11 are respectively mounted with a first support member 15 and a second support member 16. The first support member 15 and the second support member 16 each have a plurality of retaining portions 151 or 161. The heating tubes 12 are secured to the first support member 15 and the second support member 16, each having a first electrode 13 disposed at one end in contact with the associating retaining portion 151 of the first support member 15 and a second ...

Abstract

A heating device includes a heating unit, which is formed of a rack, a motor and a fan blade assembly, and a heating unit, which is formed of a carrier holding a number of quarts glass or ceramic heating tubes that are coated with a first electrode and a second electrode prepared from nanometered electric radiant film. The heating tubes emit far infrared rays and radiate heat when the fan delivery unit is delivering currents of air through the heating unit.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to heating devices and more particularly, to such a heating device, which emits far infrared rays when producing heat and, which has the advantages of high thermal efficiency, low electromagnetic wave, ease of fabrication, and recyclable materials. [0003] 2. Description of the Related Art [0004] Many different hair-dryers are commercially available. These hair dryers include conventional hair dryers, negative ion hair dryers, far infrared hair dryers. Taiwan Patent 93221183 discloses a temperature regulation hair dryer, which comprises a hair dryer body, a temperature sensor, a control member, and a display screen. The hair dryer body has installed therein a fan and an electric heating net. The hair dryer body also has an air output port for sending out hot air. The temperature sensor is installed in the air output port of the hair dryer body and electrically connected to the display sc...
