Abstract

PURPOSE:To provide an electrical panel heater capable of dispersing much radiation heat effective for heating without permitting the temperature of a heat radiation part to be abnormarily raised. CONSTITUTION:A heat radiation part 1 is comprised of many parallel flat plate-shaped heat radiation plates 2 opposed to each other, and cylindrical pipes 3a, 3b for connection of those heat radiation plates by penetrating them at upper and lower portions thereof. A paint comprising a mixture of ceramic powder 7 and epoxy resin 8 is applied on the surface of the heat radiation part 1. Hereby, as the heat radiation part 1 gets high temperature with the aid of an electrical heater, the ceramic powder 7 applied on the surface of the heat radiation part 1 radiates far infrared rays to ensure a radiation heating effect even at locations of persons to be heated far away from the heater.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric panel heater in which a flame-retardant oil sealed inside a heat radiating plate is warmed in a heat generating portion, and the oil circulates and radiates and heats.

[0002]

2. Description of the Related Art In recent years, electric panel heaters have been widely used because they are quiet and have excellent safety without fear of polluting the air.

Conventionally, this type of electric panel heater has a structure as shown in FIG. The configuration will be described below with reference to the drawings.

As shown in FIG. 3, the heat radiating portion 101 comprises a large number of heat radiating fins 102 arranged facing each other and in parallel, and hollow pipes 103a and 103b penetrating and connecting two upper and lower portions of these heat radiating fins 102. Has been formed. A thin tube (not shown) is formed integrally with each of the heat radiation fins 102, communicates with the hollow pipes 103a and 103b, and flame-retardant oil 104 is injected into the hollow pipes 103a and 103b and the thin tubes. A heating heater 105 is hermetically fixed to the lower hollow pipe 103b,
The flame-retardant oil 104 is heated to heat the hollow pipe 103a,
The thin tubes 103b and the radiation fins 102 are circulated. The heat radiating portion 101 is coated with an epoxy paint in order to maintain the purpose of rust prevention and maintain its appearance.

In the above structure, when the heating heater 105 is energized, the flame-retardant oil 1 stored in the heat radiating portion 101 is
04 is warmed and circulates, the heat is conducted to the heat radiating portion 101, the heat radiating portion 101 becomes high temperature, radiant heat is radiated from the surface, and the room is heated by convection of warmed air.

[0006]

In such a conventional electric panel heater, indoor heating is performed by heat diffusion due to convective heat, but the radiant heat emitted from the surface of the heat radiating portion does not reach so far and the user does not. Had a problem that it didn't feel warm enough unless it approached the vicinity of the heat dissipation part.

Even if the surface temperature of the radiating fins is increased to generate more radiant heat than in the conventional example, the surface of the heat radiating portion becomes a dangerous temperature at which burns or the like occur, so the temperature can be raised above a certain temperature. It had the problem of not having it.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an electric panel heater capable of radiating a large amount of radiant heat effective for heating without raising the temperature of the heat radiating section abnormally.

[0009]

In order to achieve the above object, the present invention provides a plurality of flat plate-shaped heat radiating plates which are arranged in parallel to each other and are provided with a cylindrical pipe which penetrates and connects the heat radiating plates. , A thin tube communicating with the hollow cylinder is integrally formed with the heat dissipation plate, and flame-retardant oil circulating in the hollow cylinder and the thin tube is filled inside, and ceramic powder is applied to an epoxy resin on the surface of the heat dissipation plate. It is configured to be coated with the mixed paint.

[0010]

According to the present invention, the ceramic powder applied to the surface of the heat radiating portion is heated by the above-mentioned structure, and a large amount of far infrared rays are radiated at a relatively low temperature.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, the heat radiating portion 1 is composed of a large number of flat plate heat radiating plates 2 arranged facing each other in parallel with a cylindrical pipe 3a penetrating two upper and lower portions of the heat radiating plate 2 and connecting them. 3b
It consists of and. An electric heater 4 is enclosed and fixed in the lower cylindrical pipe 3b, and is constituted by a flame-retardant oil 5 injected inside. An electric equipment case 6 is attached to the heat radiating plate 2 a which is one end of the heat radiating portion 1. The surface of the heat radiating portion 1 is coated with a paint in which a ceramic powder 7 and an epoxy resin 8 are mixed, as shown by the diagonal lines in FIG.

In the above structure, when electricity is applied, the flame-retardant oil 5 injected into the heat radiating portion 1 is warmed by the electric heater 4 and circulates, and the heat is conducted to the heat radiating portion 1 to raise the temperature of the heat radiating portion 1.

It is well known that heating ceramics emits far infrared rays. Therefore, a large amount of far infrared rays can be radiated from the ceramic powder 7 applied to the surface of the heat dissipation portion 1.

As described above, according to the electric panel heater of the embodiment of the present invention, a large amount of far-infrared rays can be radiated without increasing the surface temperature of the heat radiating portion 1 as compared with the conventional case. The heating effect can be enhanced.

[0016]

As is apparent from the above embodiments, according to the present invention, a large amount of far infrared rays is emitted by applying a ceramic powder to the surface of the heat radiating portion, and the radiation is radiated even at a position distant from the warmer. The heating effect can be obtained. Also,
Since the heating effect can be enhanced without raising the surface temperature of the heat radiating section abnormally, it is possible to provide an electric panel heater which is less likely to cause burns and the like and can be economically operated.
