均一に輻射熱Ｂがでないことにより、被加熱物１
１の加熱分布も悪い結果となる。 The problem with the heating method is that the red-hot wire mesh 10 does not uniformly generate radiant heat B, resulting in uneven heating of the object 11. That is, as shown in FIG. 2, when a part of the combustion flame A that hits the wire mesh 10 hits the wire mesh 10,
The flow of the combustion flame A is obstructed by the mesh, and the combustion flame A burns in the vicinity of the wire mesh 10 that it comes into contact with, as indicated by A', and the area that the combustion flame A comes into contact with is locally heated. The direct heating of the wire mesh 10 by the combustion flame A is limited to the portion 10a of the wire mesh 10 that is hit by the combustion flame A, and the other portion 10b is heated by the conductive heat transmitted from the portion 10a.
Therefore, the temperature distribution of the wire mesh 10 is lower at the ceiling of the portion 10b, and accordingly, the radiant heat B radiated from the wire mesh 10 also differs between the radiant heat B 1 of the ceiling and the radiant heat B 2 of the side wall. Since the radiant heat B is not uniformly distributed through the wire mesh 10, the object to be heated 1
The heating distribution of No. 1 also gives poor results.

をもつものである。Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a burner using gas or oil as an energy source and having a large number of flame holes that form a belt-shaped combustion flame, and a heat-resistant surface part that heats the inside. and a wall forming a chamber, the surface portion is formed to have a substantially concave spherical cross section sufficient to guide the band-shaped combustion flame, and the band-shaped combustion flame is held at an appropriate angle with respect to this surface portion. This is a radiation heating cooking device that brings the inner flame of a combustion flame into colliding contact with a surface portion, extends the combustion flame along the surface portion, and heats an object to be heated with the radiant heat of the extended combustion flame, and according to this, Since radiant heat can be uniformly generated after the combustion flame is formed in the burner, it has the effect of uniformly heating the object to be heated.

側に向かつて相対位置している。 In FIGS. 3 and 4, 1 is a grill body, 2 is a heating chamber formed in the grill body 1, 3 is a bottom plate forming the bottom of the heating chamber 2, 4 is a side part of the heating chamber 2,
and a wall forming the ceiling. This wall 4
The whole is made of a heat-resistant material such as stainless steel or ceramic, or only the surface portion 4a located on the heating chamber 2 side is made of the heat-resistant material. Furthermore, the surface portion 4a is finished in a smooth, continuous, non-porous concave spherical shape. However, there may be some unevenness. On the bottom plate 3 in the heating chamber 2, a removably provided soup tray 5, a shelf board 5a, and objects to be heated 6 such as fish and bread are accommodated. Reference numeral 7 denotes an exhaust groove opened approximately in the center of the ceiling of the wall 4, and 8 a burner using gas or oil as an energy source. In this embodiment, a rod-shaped Bunsen type gas burner is used. This burner 8 has a large number of flame holes 8a formed in series at intervals so that a belt-shaped combustion flame A is formed. Further, in this embodiment, this burner 8 is connected to a lower surface portion 4a of the heating chamber 2.
Two flame holes 8a are arranged near the surface part 4a.
It is located relative to the other side.

５図に示すように形成すると、燃焼炎Ａは炎孔８

Ａにより加熱された面部４ａより輻射熱Ｂが被加
熱物６に向つて放射され、これにより被加熱物６
は加熱される。 When a belt-shaped combustion flame A is formed in the flame hole 8a of the burner 8 as shown in FIG.
Since a is directed toward the surface portion 4a, the fuel collides with the surface portion 4a at an angle α and burns. Since the surface portion 4a is finished in a smooth continuous concave spherical shape with no holes, the combustion flame A that collides with the surface portion 4a immediately after the combustion flame A is formed in the flame hole 8a, using the surface portion 4a as a guide. extends upward along the Radiant heat B is radiated toward the object to be heated 6 from the extended combustion flame A and from the surface portion 4a heated by the combustion flame A, and as a result, the object to be heated 6
is heated.

熱される面部４ａの温度が均一になるとともに、
燃焼炎Ａ自体の直接加熱であるため、面部４ａよ
り均一に輻射熱Ｂが放射され、被加熱物６の温度
分布を均一にすることができる。 In the radiation heating method described above, the combustion flame A extends to the top of the surface portion 4a, so that the temperature of the surface portion 4a heated by the combustion flame A becomes uniform, and
Since the combustion flame A itself is directly heated, the radiant heat B is uniformly radiated from the surface portion 4a, and the temperature distribution of the heated object 6 can be made uniform.

びたが、今一歩輻射範囲が狭く、満足のいくもの
でない。 In the experiment according to the present invention, a Bunsen type gas burner 8 was used and the gas pressure was increased using natural gas 13A.
Under the conditions of 200 mAq and calorific value of 1200 Kcal/h, when the combustion flame A is burned without collision contact with the surface part 4a, the flame length is about 30 mm, and under the same conditions, as shown in Fig. 5, the flame length is about 30 mm. When the outer flame A1 of the combustion flame A collides with the surface 4a at an angle of 40 degrees, the flame length of the combustion flame A is about 60 mm, which is about 30 mm longer than when it does not hit the surface 4a. Although it has been extended, the radiation range is still narrow and unsatisfactory.
そこで、第６図に示すように、前記と同角度を
もつて燃焼炎Ａの内炎A2部分まで面部４ａに衝
突接触させたところ、燃焼炎Ａの炎長は90mm程度
となり、外炎A1のみを当てた場合よりさらに30
mm程度延びた。すなわち、燃焼炎Ａをその内炎
A2部分まで面部４ａに衝突接触させる方がよく
長く燃焼炎Ａを延ばすことができ、これによれば
輻射熱Ｂの輻射範囲をより広くできるので、被加
熱物６に対して均一に加熱できるとともに、大き
な被加熱物６であつても、有効に加熱できる利点
がある。 Therefore, as shown in Fig. 6, when up to two parts of the inner flame A of the combustion flame A are brought into collision contact with the surface part 4a at the same angle as above, the flame length of the combustion flame A becomes about 90 mm, and the outer flame A 30 more than if you hit only 1
It was extended by about mm. In other words, combustion flame A is its inner flame.
It is better to make collision contact with the surface part 4a up to the A 2 part, and the combustion flame A can be extended for a long time. Accordingly, the radiant range of the radiant heat B can be made wider, so that the object to be heated 6 can be heated uniformly. , there is an advantage that even a large object 6 to be heated can be heated effectively.

できるという利点がある。Effects of the Invention As described above, in the present invention, the wall that forms the heating chamber inside is formed with a substantially concave spherical cross section, so that the combustion flame can spread smoothly and in the width direction. In addition to being able to expand, the inner flame of the combustion flame collides with the surface, so the combustion flame can be further extended and expanded, and almost the entire area of the wall can be heated uniformly, so that the objects to be heated in the heating chamber can be heated evenly. It has the advantage of being able to be heated.
