Description

Electric Heater {ELECTRIC HEATER}

The present invention relates to an electric heater, and more particularly, to an electric heater that can more easily assemble and disassemble the heating element, can block ultraviolet rays as a simpler structure, and can evenly reflect thermal energy.

In general, halogen is a five-element element of fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and statin (At) belonging to group 7B of the periodic table, also called a halogen group element. It has the property of making salts (ionic compounds) easily with strong metal elements.

The halogens are systematically varied from fluorine, which is a colorless gas, to chlorine, which is a yellowish green gas, bromine, which is a reddish brown liquid, and iodine, which is a black purple solid.

Since the atomic number (nuclear charge and number of electrons) is one less than that of the Group 0 element, electrons are easily accepted and become monovalent anions, so that positive metals and strong ionic compounds can be easily formed.

It is also possible to form covalent compounds with weak and benign metals and nonmetals, in which the chemical bonds are generally polar and the halogen atoms are negatively charged.

Specifically, the halogen heating element may be manufactured by encapsulating a halogen material with tungsten filament in a quartz tube. When power is applied to the halogen heating element, the tungsten evaporated by the high temperature heat of the filament is converted into tungsten halide by combining with the halogen atom or molecule, and then reaches the high temperature filament through diffusion or convection to return to tungsten and halogen again. After dissociation, tungsten dissipates heat and light energy through the circulation of the halogen cycle back to the filament.

On the other hand, ultraviolet light among the light energy emitted from the halogen heating element should be able to be blocked as much as possible because it may have adverse effects such as acute conjunctivitis or skin disease when viewed directly by the naked eye, while heat energy emitted from the halogen heating element should be prevented. It is good to be able to reflect the heat in all directions as much as possible to raise the temperature of the whole.

As such an example, a so-called electric fan type heater which can rotate left and right or three-dimensionally and can expect the effect of warm air using a timer and a fan is rapidly spreading.

Accordingly, the present applicant is to provide an electric heater that can evenly reflect the heat energy emitted from the halogen heating element to the surroundings and to block light energy that may adversely affect the human body such as ultraviolet rays and to facilitate the assembly and disassembly thereof. I would like to propose below.

The present invention has been made through the above-described proposal, and the purpose of the present invention is that the auxiliary reflector for fixing the heating element is designed to be combined by the fitting of the support and the protrusion, and by adding a guide groove for receiving the lead wire The parts of the assembly can be more simply assembled and the heating element can be tightly fixed to the auxiliary reflector by a fixing pin having a bent portion to provide an electric heater that can be used more stably.

As a preferred embodiment, as shown in Figure 2 and 3, the electric heater 100 according to the present invention is a main reflector for reflecting in one direction the heat energy emitted from the heating element (10) having a lead wire ( And an auxiliary reflecting plate 30 which is fixed by the fixing member 50 with the cylindrical support 40 positioned in the center of 20.

At this time, the heating element 10 may utilize a circular, hexagonal, octagonal or decagonal shape is not limited to such a shape. Then, the two lead wires 11 drawn from both ends of the heating element 10 may be drawn out toward the inner center thereof.

For example, when the lead wire 11 of the heating element 10 is drawn outward, the lead wire 11 is drawn out toward the inner center because the electric wire 100 may have an uncomfortable effect on the overall shape of the electric heater 100. By taking the structure to be able to be able to be built into the cylindrical support (40).

Accordingly, the electric heater 100 according to the present invention includes a guide groove 32 recessed to receive the lead wire 11 on the rear surface of the auxiliary reflector 30 and guide the inside of the support 40.
