Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a type of grilled food cooker in which a gas infrared burner is provided facing the food to be cooked on a generally rectangular front heat radiating surface having a large number of combustion holes.

Originally, in this type of cooker, the heat distribution of the heat radiating surface of the burner is high in the longitudinal center part, which tends to cause the cooked food to be unevenly cooked.
As described in Japanese Patent No. 9-28110, it is known that the center part is a part without combustion holes so that the heat distribution can be made uniform, but in this case, both longitudinal sides of the heat radiating surface are divided at the center part. As a result, there is no transfer of fire between the two parts, and a separate ignition device must be provided for each part, resulting in a complicated structure.

The purpose of the present invention is to provide a cooking device that eliminates such inconvenience.
In a type that is provided facing the food a on a substantially rectangular front heat radiating surface 2 having a large number of combustion holes 3,
The central portion in the longitudinal direction of the heat radiating surface 2 is divided into a plurality of band-shaped portions extending substantially parallel to the longitudinal direction, one portion of which is left in the area where the combustion holes 3 are formed, and the other portions where no combustion holes 3 are formed. It is characterized by being formed into parts.

Fig. 1 shows the entire system, in which a pair of gas infrared burners 1 are arranged side by side on the upper surface of a heating chamber 5 in the cooking device main body 4, and the food a is placed on the lower surface of the burner so that it can be freely accessed and removed from the front. to be accommodated.

The heat radiation surface 2 of each burner 1 has three combustion plates 2a, 2b, 2C located in the longitudinal center portion and both side portions of the burner body 1a, as shown in FIGS. 3 and 4, for example. The gas distribution chamber 1b is formed by being airtightly fitted to the front surface of the gas distribution chamber 1b. In this case, the combustion plates 2a and 2C on both sides are provided with combustion holes 3 over the entire surface, but the combustion plate 2b in the center part is provided with combustion holes 3 over the entire surface.
The heat radiating surface 2 is divided into three parts: the side edges on both sides parallel to the longitudinal direction and the center part, and the center part is left in the area where the combustion holes 3 are formed, and the side edges on both sides are formed without the combustion holes 3. formed into parts,
The distribution area of the combustion holes 3 was correspondingly reduced.

Incidentally, this kind of combustion plate is generally made by firing ceramic, and if such a plate is provided with a part with combustion holes 3 and a part without it, thermal distortion occurs during firing and cracks are likely to occur. Therefore, in order to prevent this, for example, as clearly shown in FIG. 5, a blind hole 3a is provided in a portion where there is no combustion hole 3.

As described above, according to the present invention, the longitudinal center portion of the heat radiating surface 2 is divided into a plurality of strip-shaped portions extending approximately parallel to the longitudinal direction, and one portion is left in the area where the combustion hole 3 is formed and the other portions are separated. The area where the combustion holes 3 are not present is formed in the central part, and the distribution area of the combustion holes 3 in the central part is reduced compared to the parts on both sides, thereby making the heat distribution uniform. Good transfer of fire between the two side parts is achieved through the part where the combustion hole 3 is formed, which has the effect of reliably eliminating the disadvantages of the conventional type described above.
