Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baking cooker having an infrared burner provided with a heat radiation surface having a large number of combustion holes facing a food item.

2. Description of the Related Art A conventional baking cooker of this type is shown in FIGS.
The baking cooker 1 is configured such that a plurality of planar heat radiation plates 3 are provided on a gas infrared burner 2 to form a combustion section 4 and a plurality of gas infrared burners 2 face a cooking chamber 5. The gas infrared burner 2 forms a main body 7 by sandwiching and welding a plurality of press-formed products 6a and 6b, and the main body 7 holds the outer circumference of the heat radiation plate 3 to radiate heat into the cooking chamber 5. In order to prevent the plate 3 from falling, another press-formed product 8 is attached to the outer periphery of the heat radiation plate 3 and installed in the cooking chamber 5. An exhaust port 9 is formed on the upper surface of the cooking chamber 5. The heat radiation plate 3 is generally made of ceramic or the like in a substantially rectangular shape, and has a ceramic A 12 provided with a large number of combustion holes 11 on the front surface of the surface 10 and a portion 13 having no combustion holes 11 in the periphery. The ceramic B14 provided is combined with each other. In addition, a grill 15 is placed in the cooking chamber 5 in correspondence with the gas infrared burner 2 to put food on it, and the gas supplied to the heat radiation plate 3 of the gas infrared burner 2 burns. The radiant heat is emitted by heating the vicinity of the combustion hole 11 of the heat radiation plate 3 to make it red heat, and the radiant heat is not emitted at the portion 13 without the combustion hole 11 and is placed on the grill facing the gas infrared burner 2. The cooked food is cooked by radiant heat and is used as the baking cooker 1.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the conventional configuration as described above, the heat radiation plate 3 that constitutes the gas infrared burner 2 does not partially include the ceramic A12 having a large number of combustion holes 11 and the combustion holes 11. Because of the combination with the ceramic B14 having the portion 13, two different types of ceramic A12 and ceramic B14 are required to form the gas infrared burner 2.
That is, a die for making the ceramic A12 and the ceramic B14 is required to construct the gas infrared burner 2.
The mold for making the ceramic A12 or the ceramic B14 has a large number of pins for forming the combustion holes 11, and since the pins are processed by pressing the ceramic material, the surface of the pins is polished by the ceramic material. The state of the combustion hole 11 becomes thin during press working, so that the diameter of the combustion hole 11 changes to various sizes depending on the product. Therefore, even if the same gas is supplied to the ceramic A12 and the ceramic B14, because the diameter of the combustion hole 11 is different, a difference in the amount of combustion occurs between the two, the surface red heat temperature is different, the cooked food heated by radiant heat There was a problem that good cooking performance could not be obtained due to partial burning or non-burning.
In addition, since the baking cooker requires a plurality of gas infrared burners, for example, if two ceramics are required for each gas infrared burner, the number of ceramics is twice as much as that of the gas infrared burner. There was a problem that the work increased and the cost increased. The present invention solves the above conventional problems, and aims to improve the cooking performance of a baking cooker and at the same time improve the assemblability of a gas infrared burner, and at the same time, reduce the number of parts and reduce the cost. To do.

Means for Solving the Problems In order to solve the above problems, the baking cooker of the present invention has a heat radiating plate composed of a plurality of ceramic plates of the same shape having a large number of combustion holes, and cooking the heat radiating plate. A gas infrared burner provided on the upper surface of the cooking chamber facing the object and a baking cooker body, and the gas infrared burner has an outer peripheral red heat section having combustion holes provided along substantially the outer edge of the heat radiation plate. And a heat radiating plate having a non-red heat part having no combustion holes inside the outer peripheral red heat part, and a burner body for fitting and fixing the outermost peripheral parts of the plurality of heat radiating plates, and the burner body is mixed. A first press-molded product in which a tube portion and a mixing chamber are integrally molded and a second press-molded product in which a box-shaped bottom portion is opened and the outer peripheral edge of the opening portion is opened to the outside are overlapped and integrated, and the opening is formed. The heat radiating plate is fitted into the section and the baking cooker book The upper case of the body is provided with a recess in which the infrared burner can be placed from above.

Action The present invention has the above-described configuration, and since the gas radiation burner is composed of the same type of heat radiation plate (same mold), the number of combustion holes in the heat radiation plate are all uniform and burned. At this time, there is no difference in the combustion state between the two, the surface red heat temperature becomes uniform, and the temperature of the cooked food can be adjusted by the part without combustion holes, so the cooked food heated by heat radiation partially burns. It is possible to obtain good cooking performance without being burnt or burning.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.
The parts having the same functions as those of the related art are designated by the same reference numerals and the description thereof will be omitted.

In FIGS. 1 and 2, the combustion cooker 1 is a cooker body 4
The gas infrared burner 2 causes the red hot surface of the heat radiating plate 3 to be cooked on the upper case 4a of the cooker main body which is opened on the upper side facing the food on the grill 15 provided below the cooking chamber 5 inside It is placed toward.

The burner body of the infrared burner 2 is composed of two pressed parts. That is, the mixing pipe portion 17a and the mixing chamber 17b are integrally molded with the first press-molded product 17 and has a substantially box-shaped opening 19 having an opening at the bottom, and the opening edge is bent outwardly. The second press-formed product 18 having the curved portion 20 is formed by superposing one on the other and integrally formed, and the opening of the second press-formed product 18 is formed.
The heat radiation plate 3 made of two ceramic materials of the same shape is inserted and fixed from the bent portion 20 of 19. The heat radiation plate 3 is near the outer circumference
Since a large number of combustion holes 11 are provided in 21 and the inside 22 of this outer peripheral area 21 is on a plane without the combustion holes 11, it is near the outer edge.
21 burns red due to combustion, but the inside 22 does not glow red.

The infrared burner 2 thus configured is placed in the recess 4b of the upper case 4a above the cooker body 4 of the baking cooker 1.

In the above configuration, the heat radiation plate 3 of the gas infrared burner 2
Are the same and bonded to the same plane, so the heat radiation surface 3
Since the diameters of the numerous combustion holes 11 are always uniform, there is no difference in the combustion state between the two when burning, the surface red heat temperature becomes uniform, and the cooked food heated by radiant heat is Good cooking performance can be obtained without partial burning or non-burning. Also, 1 for baking cooker 1
Since the book gas infrared burner 2 is provided, only one type of the heat radiation plate is required, so that the processing work is reduced and the cost is reduced. In addition, it has a substantially rectangular outer shape, and has a substantially planar inner surface 22 that does not have combustion holes 11 in the substantially inner portion.
By using the heat radiation plate 3 having the combustion hole 11 in the vicinity of the outer circumference 21 of the inner side 22, there is no combustion hole 11 in the central portion of the gas infrared burner 2 The food set in the
It is heated by the heat of combustion in and good cooking conditions are obtained. Further, the temperature can be freely set only by adjusting the number of combustion holes 11. On the contrary, when the combustion hole 11 is provided in the inner side 22, the temperature of the central portion of the cooking chamber 5 becomes relatively high due to the temperature of the end portion, and the cooking material set in the central portion is cooked in the end portion. As a result, it burns faster than the food, and good cooking performance cannot be obtained.

Effects of the Invention As described above, according to the combustion cooker of the present invention, the following effects are obtained.

(1) Since the heat radiating plates of the gas infrared burner are the same and are configured in the same plane, the diameters of many combustion holes in the heat radiating plate are all uniform, so when burned, there is a difference in the combustion state between the two. The red hot temperature on the surface becomes uniform without the occurrence of heat, and the cooked food heated by the radiant heat is not partially burnt or not burned, and good cooking performance can be obtained.

(2) A heat radiation plate having a substantially rectangular outer shape and having a combustion hole inside, and a combustion hole provided on the outer periphery of the flat portion is used, so that the central portion of the gas infrared burner is Since there is no combustion hole, there is no combustion heat when burning, and the food set directly under this part is heated by the combustion heat from the combustion hole provided on the outer periphery, and a good cooking state can be obtained. .

(3) When the heat radiation plate is attached to the burner body, since there is an outward bent portion at the inlet of the burner body, it is easy to attach and the heat radiation plate is not damaged.
