Embodiment Construction

[0024] Refer below Figure 1 to Figure 6 Embodiments of the hot air heater according to the present invention are described. The embodiments described below illustrate examples of hair dryers. Like numbers represent like elements throughout the drawings.

[0025] First, a first embodiment of the hot air dryer according to the present invention will be described. Such as figure 1 As shown, the hot air dryer 1 includes an insulated refractory support 2 wrapped with a heating wire 3 . The heating wire 3 is wound in a direction in which hot air flows from the hot air dryer 1 or in the opposite direction to form a coil.

[0026] The insulating refractory support 2 can be made of mica sheet, ceramic sheet or the like. figure 1 The insulating refractory support 2 shown in is made of crossed plate-like bodies. The heating wire 3 can consist of a helical nichrome alloy or the like. exist figure 1 , the number 4 represents the fan motor, and the number 5 represents the fan.

Abstract

In the hot air heater, the heating wires 3a and 3b are wound around the insulating refractory substrate, so that the current flowing through the heating wires 3a and 3b flows in opposite directions to cancel the electromagnetic waves generated by the heating wires 3a and 3b, thereby reducing the heat from the hot air. Electromagnetic waves emitted by the heater.

Description

[0001] Technical field [0002] The present invention relates to hot air heaters, such as hair dryers, desktop hot air heaters and the like. Background technique [0003] Known hot air heaters have a heating element such as a nickel-chromium heating wire wrapped around an insulating refractory substrate such as mica board. [0004] There is also known a hot air heater in which shaped carbon is additionally attached to a hot air nozzle to increase the far-infrared ray effect generated by the shaped carbon (for example, Japanese Utility Model Registration Publication No. 3011964). [0005] Electromagnetic waves are usually divided into radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays in order from the longest wavelength to the shortest wavelength (that is, from the lowest frequency to the highest frequency). And the shorter the wavelength, the greater the photon energy. When visible or ultraviolet light illuminates a substance, these electrom...
