照）。As shown in FIGS. 6, 7 and 8, a ceramic burner 62 disposed in the burner body 61 has a burning surface provided with a convex portion 64 having a flame opening 63 and a concave portion 65 having no flame opening. There is a gas cooker 68 in which an infrared burner 66 having a configuration alternately provided is installed in a baking chamber 67. Usually, a gas switchgear 69 for a stove burner and the infrared burner 66 are connected, and a pressure regulator 70 such as a gas governor is provided. An infrared burner gas opening / closing device 71 having a built-in gas is installed in the gas flow path 72 so that the supply gas pressure fluctuation does not reach the infrared burner 66 on the downstream side (see, for example, JP-A-1-234707). ).

狭くなっていた。In this structure, the concave portion 65 is used as a flameless opening area to reduce the heat capacity of the convex portion 6 having the flame opening 63.
Although the combustibility is ensured by alternately sandwiching it by 4, the whole surface of the ceramic combustion plate 62 is a combustion surface, and the central portion of the combustion surface inevitably rises in temperature, and when the combustion amount is increased, the central portion of the combustion surface is increased. Since it is easy to cause a flashback, it is necessary to keep the thickness of the ceramic combustion plate 62 thick to some extent. (Actually, about 13 to 15 mm is also required.) On the other hand, when the amount of combustion is reduced, the peripheral end portion of the ceramic combustion plate 62 is most affected by the cooling due to the above-mentioned plate thickness, which deteriorates the overall combustibility. Was there. Thus, in order to prevent flashback, the range of variable combustion amount was narrowed as a result.

の課題があった。Therefore, a pressure regulator 70 such as a gas governor was indispensable in the gas passage 72 connected to the infrared burner 66. Therefore, the gas switchgear 69 for the stove burner and the gas switchgear 71 for the infrared burner have different basic configurations, resulting in a significant cost increase. Further, since the thickness of the ceramic combustion plate 62 is increased, the ventilation resistance when the fuel premixture passes through the flame port 63 also increases, and in order to secure an ideal combustion air amount, the mixing pipe length of the burner body 61 is increased. Therefore, a considerable margin is required for the configuration such as increasing the length, and the entire infrared burner 66 must be thick and large. Infrared burner 66 like this
When applied to a baking cooker 68 that requires a wide range of heat control and a generous internal volume, a good cooking result cannot be obtained and a wide cooking menu cannot be supported due to the internal volume. Not only the issue, but also the issue of cost increase.

An infrared burner 86 is provided in which the flame opening area on the combustion surface 84 side of the ceramic combustion plate 83 having a plurality of penetrating openings 82 arranged therein is larger than the flame opening area of the surface 85 on the fuel mixed gas inflow side. (See, for example, JP-A-62-80416).

していた。In this configuration, the combustion area 84 side has a larger flame opening area than the combustion surface inflow side surface 85, thereby realizing high load combustion. The generated flame retreats into the inside of the ceramic burner 83, and a heat retention phenomenon occurs to facilitate backfire.
In order to prevent flashback, the thickness of the ceramic burner plate 83 must be increased. Therefore, due to the heat retention phenomenon, the ventilation resistance when the fuel premixture passes through the flame port 82 increases, and in order to secure an ideal amount of combustion air, there is a considerable margin in the configuration of the mixing pipe of the burner body 81. Was needed.
The combustion state at a low combustion amount is the ceramic combustion plate 83
Due to the promotion of cooling due to the thickness of CO, CO emission was increased, and a wide combustion amount variable range could not be obtained. Therefore, similarly to the above-mentioned other conventional configuration, the gas flow path connected to the infrared burner 86 always requires a pressure regulator such as a gas governor.

There is an infrared burner 95 in which a heating plate 94 made of a heat-resistant metal is provided over the entire flame opening region (see, for example, Japanese Utility Model Laid-Open No. 1-136241).

高コストになるという欠点があった。In this structure, the temperature of the peripheral edge of the flameless opening area of the ceramic combustion board 93 is kept higher to ensure combustibility, but the flameless opening area is formed in the central portion of the burner body 91. Therefore, the structure becomes complicated, and a separate member such as the heating plate 94 is required, and since four ceramic combustion plates 93 are fixedly arranged in the burner body 91 without a gap, the number of working steps is increased. It had the drawback of being extremely expensive.

った問題点を有していた。As described above, in the conventional structure, the infrared burners 66 and 86 are the ceramic burner 6
In order to prevent flashback from 2 and 83, it is necessary to keep the thickness of the ceramic burner plates 62 and 83 thick, which narrows the combustion amount variable range and prevents unstable combustion due to pressure fluctuations. In addition, the gas flow passage 72 requires a pressure regulator 70 such as a gas governor, and the thick ceramic burners 62 and 83 increase the ventilation resistance of the fuel pre-mixture, which is ideal. In order to secure a proper combustion air amount, a considerable margin is required in the design of the mixing tubes of the burner main bodies 61 and 81, and in order to secure combustibility like the infrared burner 91, the burner main body 91 There is a problem of high cost such as a complicated structure, a separate heating plate 94, and an increase in the number of work steps. Further, the infrared burner 66 is used.
When used as a burner for cooking of the baking cooker 68, there was a problem that the cooking space was narrowed and a good cooking result could not be obtained.

め、均一な輻射分布を確保することができる。As described above, according to the present embodiment, the substantially flame-shaped outer peripheral flame mouth portion 24 is provided on the outer periphery of the ceramic combustion platen 22, so that the heat at the time of high load combustion is effectively absorbed by the ceramic combustion platen 22. By releasing the heat from the outer periphery to suppress heat retention, and by forming the non-flame area 25 surrounded by the outer flame opening 24,
Since the flame opening is removed from the vicinity of the center of the ceramic combustion board 22 where unstable combustion is likely to occur, a wide combustion amount variable range can be secured, and the additional flame opening 26 is provided toward the center of the surface of the ceramic combustion board 22. As a result, the radiant heat generated by the combustion in the additional flame port 26 extends to the vicinity of the central portion, and the loss of heat in the flameless port region 25 can be covered, so that a uniform radiation distribution can be secured.

る。As described above, according to this embodiment, the heat capacity of the ceramic burner plate 31 itself is reduced to suppress the cooling at the time of low load combustion to maintain the combustibility and suppress the emission of CO, and at the same time, The flame-free area 25 allows the overall strength to be maintained while removing the flame area from the vicinity of the central portion of the ceramic combustion board 31 where unstable combustion is likely to occur, so that a thin and wide combustion amount variable range can be obtained, and at the same time, the fuel prediction can be performed. Because it is possible to reduce the ventilation resistance when the mixture passes through the flame mouth,
The mixing tube 33 of the burner case 32 can be made compact, and as a result, the thickness of the entire infrared burner 34 can be reduced.
