Description

Radiation type electric heater with heating part in safety net

The present invention relates to a radiation-type electric heater provided with a heating unit in the safety net, and more specifically, by installing the heating unit, which is a heat source, in the center of the safety net, not the reflector, all heat rays generated from the heat source can be reflected as radiant heat through the entire reflector. It relates to a radiation-type electric heater equipped with a heating unit in the invented safety net so that the heating efficiency is maximized and the power consumption is reduced to a minimum through the method to reduce the economic burden of the user.

As a result of the improvement in living standards, the hearth of the indoor heating system is also a situation where electric heaters have become more common as they have escaped from the methods of the past, and various types of electric heaters have been developed as social demand increases. Of course.

As is well known, the basic operating principle is to heat the surrounding air with heat generated at this time by passing an electric current to an electric heating wire in a certain space protected by a safety net, and additionally related to other accessories for dissipating heat from the electric heating wire more efficiently. The device is attached.

As one of the representative examples, an electric heater in which a reflector made by bending a thin metal plate is installed at the rear of a heating wire is widely used, but it has not achieved much effect.

Such a conventional electric heater has a problem in that it does not properly send a sufficient amount of heat to a distance that satisfies a sufficient amount. However, if the current amount is increased to increase the generated heat itself, there is a risk of overheating and fire, but a safety accident due to this When the amount of current is reduced consciously, it is difficult to obtain a satisfactory amount of heat.

In order to solve the problems of the electric heater, a radiant electric heater capable of sufficiently heating the indoor air by sending an appropriate amount of heat as far as possible has been developed as a domestic public utility number 1998-61527.

The radiation-type electric heater is provided with a reflector (spherical) formed on a spherical surface behind the heating wire, while heat is not diffused in all directions but is concentrated within a narrow range and transmitted to a far distance by forming a shape having a reduced diameter while going backwards It has a feature that makes it possible.

The radiation-type electric heater 1 is generally divided into a heating portion 10 including an electric heating wire and a supporting portion 20 supporting the heating portion.

First, looking at the support 10, the main circuit for the operation and control of the radiation-type electric heater 1 is built in the base 21, and also a power switch 22 for supplying or blocking power, In order to maintain the temperature of the heating wire in a proper state, a temperature control switch 23 that regulates power based on a certain temperature, a power indicator 24 indicating whether or not the power is connected, and regulates power according to the inclination of the electric heater When the safety switch 29 is installed and, if necessary, the electric heater is inclined severely, a rotary switch for time adjustment and a rotation selection switch, etc., not shown, including a safety warning lamp 25 to call the user's attention, include the support ( 21) It is arranged at the top and bottom.

In addition, the heating unit 10 and the pedestal 20 are connected via one or two posts, but when the posts are made of two, they are installed in the coupling portion of the two

posts

26 and 27. The adjustment handle 28 is released, and the upper strut 27 can be inserted into or taken out from the lower strut 26. That is, the height of the entire heating unit 10 can be arbitrarily adjusted.

In addition, the heating part 10 is connected to the heating element 12, the heating plate 12 wound around the heating element mounting opening 11 of a certain shape, the reflective plate 13 located behind the heating element, and the reflective plate, and the heating unit ( 10) It comprises a safety net (14) forming the entire front contour and a support case (15) connected to the rear end of the reflector (13), as well as the heating wire (12) via the bracket (16) It is installed on the reflector 13, and a heat sensing rod 17 is attached to a predetermined place in front of the reflector.

In the radiant heat electric heater 1 having such a configuration, unlike the conventional structure in which the heating wires a generated in the heating wire 12 are diffused in all directions, a predetermined range C by the reflector 13, that is, Since it is concentrated in the front portion of the area corresponding to the total area of the reflector 13, as a result, it is possible to reach even a very long distance requiring heat.

At this time, the hot wires (a) reflected by the reflector 13 to the front portion do not stay around the heat generating portion 10 including the heating wire 12, and are directly radiated through the reflection process by the reflector 13 Overheating of the safety net 14 is also prevented.

Here, when the reflector 13 includes a regular spherical surface such as a regular concave mirror, and the center portion is a concave parabolic surface, the maximum concentration of heat rays can be obtained.

On the other hand, the heating wire 12 is wound, and the heating wire mounting hole 11, which is usually made of a heat-resistant material such as ceramic, is mostly conical or conical with a reduced diameter while going backwards, wherein the heating wire mounting hole ( Even if the shape of 11) is not a truncated cone, it is a triangular pyramid or other polygonal horn. That is, the same effect can be obtained if the heating wire mounting opening 11 has a reduced diameter while going backward.

The heating wire mounting hole 11 having such a configuration is intended to prevent the heating wires (a) generated from the heating wires 12 toward the total amount of the reflector 13 so that even some heating wires are dispersed outside the predetermined range (C). to be.

However, in this type of radiation type electric heater, there is a problem that the coil is corroded when used for a long time, and the durability is reduced and there is a risk of fire due to the heating wire that forms heat. Since the heating wire is wound, there is a problem in that the ceramic member receiving direct heat becomes high heat and the far-infrared radiation efficiency decreases.

Therefore, conventionally, as a method for solving the above problems, a radiant heat heater has been developed, and Korean Patent Publication No. 10-0425901 (March 26, 2004) has been proposed, which is a heater heat source (heat generation means). Lamps are used, and secondary reflectors are spaced apart to provide radiant heat in front of halogen lamps, but the secondary reflectors are fixed to the safety net.

Therefore, the reflection efficiency can be increased by reflecting heat as much as the heat of reflection through the auxiliary reflector, and since the ceramic base receives radiant heat through the halogen lamp, it is possible to increase the far-infrared emission efficiency in a low heat state.

However, in the above-mentioned reflective heat heater, instead of using a halogen lamp instead of a conventional heating wire as a heater heat source (heating means), there is a problem in that manufacturing cost increases because an auxiliary reflector must be further installed to provide radiant heat in front of the halogen lamp.

In particular, since the two conventional radiation-type electric heaters have a heater heat source that is a heating means fixedly installed in the center of the reflector, heat rays generated from the heat source are not reflected at all through the center portion of the reflector, which is covered by the heat source. Since the reflection is made only at the part that is displaced from, it is not possible to reflect the heat rays far away, and there is a problem in that the indoor heating efficiency is reduced and the power loss is large, resulting in excessive economic loss for the user.

The present invention has been devised to solve such problems in the related art, and a method of installing a heating unit, which is a heat source, in the center of a safety net instead of a reflector, so that all heat rays generated from the heat source can be reflected as radiant heat through the entire reflector. The goal is to provide a radiation-type electric heater equipped with a heating unit in a safety net that maximizes heating efficiency while minimizing power consumption while minimizing power consumption.
