なる。However, in the configuration of the conventional baking cooker described above, when the gas infrared burner 3 is burned, fresh secondary air is generated by natural convection, so that the front lower opening 6 and the rear lower opening 25. The lower opening 25 of the rear opening is located below the exhaust port 7, so that the discharge speed from the exhaust opening 7 is high, and the inflow speed of the secondary air from the lower opening 25 of the rear opening is also higher. Get faster

する。Therefore, the fresh secondary air from the front opening 6 becomes a turbulent flow phenomenon around the rear portion of the heat radiating plate 4, natural convection is not sufficiently performed, and good combustion performance cannot be obtained. Further, the outer periphery of the grill 5 on which the cooked food of the baking cooker 1 is placed is cooled by the flow of air of natural convection, and is absorbed by the heat absorption of the wall surface of the inside 2 of the grill. Although it is cooled by the flow of air, the central portion of the grill 5 is hard to cool. Therefore, when the heat radiating plate 4 of the gas infrared burner 3 is heated and red-heated, the food is not uniformly heated, and the grill is not heated. There was a problem that the central part of the was burned and uneven cooking occurred, and good cooking performance could not be obtained. The present invention solves the above conventional problems, and an object thereof is to improve the combustion performance and cooking performance of a baking cooker.

に有効な手段であることを示す。Referring to FIG. 1, a baking cooker 1 has a gas infrared burner 3 having a heat radiating plate 4 held by 14 holding frames with an inclination of a predetermined width W so that the gas infrared burner 3 faces the cooked product and is placed on the upper surface of the refrigerator 2. The infrared burner 3 has a press-formed product 15 and a fitting hole 16 for the heat radiating plate 4, and the heat radiating plate 4 is provided around the periphery of the fitting hole 16.
It is held by press-fitting with a press-molded product 17 having an open end 18 for insertion of, and a gas seal packing 19 is wound around the side faces of two heat radiation plates 4 of the same shape made of ceramic plates in the fitting hole 16. . In the above structure, the fresh secondary air that has entered the chamber 2 through the front lower opening 6 of the baking cooker 1 tilts the infrared burner 3 and installs it on the grill cover 23, so natural convection is sufficiently performed. Inclined heat radiation plate 4
The fresh secondary air sufficiently supplied to the red heat section of the baking cooker 1 and entering from the rear lower opening 25 of the baking cooker 1 enters the inside 2 through the flow straightening plate 26 and the heat radiation plate 4 of the infrared burner 3 The exhaust gas that has been supplied to and burned is discharged from the exhaust port 7. That is, the fresh secondary air entering from the rear lower opening 25 has a high inflow speed unless the flow straightening plate 26 is interposed, so that the fresh secondary air entering from the front opening 6 is disturbed at the rear of the heat radiation plate 4. It becomes a flow phenomenon, and natural convection cannot be performed sufficiently and combustion failure occurs. Therefore, the rectifying plate 26 has an effect of rectifying the fresh secondary air entering from the front lower opening 6 and the rear lower opening 25. Further, it is conceivable to further lengthen the straightening vane 26, but if it is lengthened, the radiating area on the surface of the grill 5 overhanging below the heat radiating plate 4 is reduced. Further straightening plate
If 24 is shortened, the rectification effect will be lost and combustion failure will occur. Therefore, the rectifying plate 26 is configured to be installed so as to maintain a constant space with the heat radiating plate 4 of the infrared burner 3, which shows that it is an effective means for improving combustion performance.

とを示す。Further, a configuration in which the inclination width W of the infrared burner 3 is further inclined is conceivable, but when the inclination width W is increased, the food placed on the grill 5 is not uniformly heated, and the back portion is scorched and uneven cooking occurs. . Further, when the inclination width W is made smaller, the flow velocity of the fresh secondary air flowing in from the lower opening 6 on the front surface is reduced, a turbulent flow phenomenon occurs at the rear part of the heat radiation plate 4, and the effect of installing the straightening plate 26 is reduced. Small combustion failure occurs. Therefore, it is shown that the infrared burner 3 is configured to be installed while holding a predetermined inclination width W, which is an effective means for improving combustion performance and cooking performance.
合わせて、整流板26は排気口7の下部にグリルカバー23

め掃除により容易に落下物を除去でき、焼成調理器1の
下部は常に清潔に保つことが可能である。In addition, the current plate 26 is attached to the bottom of the exhaust port 7 to cover the grill cover 23.
Since it is installed between the grill case 24 and the grill case 24, when spilled food on the stove falls from the exhaust port 7 into the chamber 2, it does not fall to the bottom of the baking cooker 1 and stain the floor surface. The fallen objects can be easily removed by cleaning because they are collected in the grill plate 27 via the straightening plate 26, and the lower part of the baking cooker 1 can be always kept clean.

ことが可能である。Further, even when the food placed on the grill 5 is accidentally ignited during cooking, the combustion air flowing in from the rear lower opening 25 intervenes the rectifying plate 26 and the heat radiating plate 4 Since the exhaust gas is supplied to the exhaust port 7, it is possible to reduce the discharge speed of the combustion exhaust gas from the exhaust port 7 and reduce the flame standing up from the exhaust port 7.
