TECHNICAL FIELD The present invention relates to a technique of incorporating a surface combustion technology into a gas appliance.

Surface combustion technology is a combustion technology that induces complete combustion by uniformly burning a gaseous fuel and air mixture on the surface of a porous medium. Has recently attracted attention because it has an effect of increasing the thermal efficiency by complete combustion, centralizing the heat transfer portion, reducing the emission of pollutants, and reducing the production of nitrogen oxides (NOx). This surface combustion technique is used in some gas burners connected to gas vessels.

Hereinafter, the operation principle of the surface combustion gas heater according to the present invention will be described.

When a flame is generated through the ignition part, the flame is moved to the heater part 140 through the coupling support part 110, so that a metal foam or the like as a porous material constituting the heater part 140 is heated. The porous material such as the metal foam of the heater unit 140 emits thermal energy while burning the surface.

However, the present gas heater is faithful to the function of the heater itself by inducing the heat energy to be radiated in the lateral direction rather than the vertical direction.

Therefore, the heater 140 itself may have a closed top surface such that the heat is not directed upward.

It is further preferable that the upper outer support plate 180 and the upper inner support plate 170 have a structure in which the center is closed in order to minimize the heat energy of the heater unit 140 from being directed upward.

It is further preferable that the lower outer support plate 120 and the lower inner support plate 130 have a central open structure in order to smoothly move the flame discharged through the coupling support unit 110 to the heater unit 140.

In the embodiment of FIG. 3, the heater 140 is disposed between the lower outer support plate 120 and the upper outer support plate 180 to emit thermal energy. In order to restrain thermal energy from going in the vertical direction, the upper outer support plate 180 is formed in a closed structure. The heater part fence 150 is disposed outside the heater part 140 so that the heat energy generated by the heater part 140 is received by the heater part fence 150 and the efficiency of the heater is increased And also serves to help radiate heat in various lateral directions.

In the embodiment of FIG. 4, the heater 140 is disposed between the lower inner support plate 130 and the upper inner support plate 170 to emit thermal energy. The upper inner support plate 170 and the upper outer support plate 180 are spaced apart from each other. By disposing two support plates above the heater unit 140, heat energy that is moved upward from the heater unit 140 is suppressed to the utmost, Thereby performing the function of directing it to the side direction.

The embodiments and the accompanying drawings described in the present specification are merely illustrative of some of the technical ideas included in the present invention. Accordingly, the embodiments disclosed herein are for the purpose of describing rather than limiting the technical spirit of the present invention, and it is apparent that the scope of the technical idea of the present invention is not limited by these embodiments. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
