Description

[Detailed Description of the Invention] The present invention relates to a gas stove using an infrared burner having an inner flame tube and an outer flame tube.

In a conventional infrared burner having a rectifying ring with the same hole diameter all around, the red-hot part of the outer flame tube on the side of the reflector was brighter than the front side of the appliance.

The present invention aims to make the red heat uniform around the entire circumference of the outer flame tube, and one embodiment thereof will be described below with reference to the drawings.

FIG. 1 shows a gas stove, where 1 is an infrared burner and 2 is a reflector.

FIG. 2 shows an infrared burner 1, with reference numeral 3 representing a burner base, which has a rectifier ring 4 inside.

An inner flame cylinder 5 made of perforated metal and an outer flame cylinder 6 made of perforated metal are mounted on the burner base 3.

An upper chamber 7 is attached above the inner flame tube 5 and the outer flame tube 6.

An outer cylinder 8 and a glass cylinder 9 are combined on the outside of the outer flame cylinder 6.

Reference numeral 10 denotes a gas cock that supplies the burner base. Gas from this cock passes through a governor 11, is rectified by a rectifying ring 4 in the burner base 3, and is ejected from a circular hole in the burner base 3.

The ejected gas 12 mixes with air 13 from the holes in the lower part of the inner flame tube 5 and the lower part of the outer flame tube 6 to form a mixed gas, and the inner flame tube 5
The air 13 from the hole in the upper part of the outer flame tube 5 and the air 13 between the upper part of the outer flame tube 5 and the glass tube 8 cause combustion, and the upper part of the outer flame tube 6 becomes red hot.

With the above configuration, if the rectifying ring 4 has a uniform hole diameter around the entire circumference as shown in Figure 3, there will be no problem with a full-circle type gas stove without a reflector. In the stove, the infrared rays from the burner are reflected on the reflector plate 2, further warming the red-hot part of the outer flame tube 6, and the side of the reflector becomes brighter than the front side of the appliance. This has caused problems such as thermal deformation of the parts and deterioration of durability.

FIG. 4 is a perspective view of the rectifying ring 4.

In order to eliminate this problem, the present invention is designed to make the diameter of the half-circumference hole on the front side of the device larger than the half-circumference hole on the reflector side among the circular holes on the entire circumference of the rectifier ring 4, as shown in Fig. 4. By doing so, the amount of gas ejected from the circular hole of the burner base 3 is reduced by the amount of infrared rays that reflect off the reflector side and warm the red-hot part of the outer flame tube 6, thereby reducing the red heat around the entire circumference of the outer flame tube 6. Made it uniform.

As described above, according to the present invention, by using the rectifying ring in the infrared burner, it was possible to make the red heat uniform over the entire circumference of the outer flame tube.
