The separator 6 has a lateral dimension smaller than the inner diameters of the support frame 5 and the cylindrical body 2 . Therefore, in a state in which both ends of the separator 6 in the longitudinal direction (front-rear direction) are placed on the stepped portion of the support frame 5, the baking chamber B and the combustion chamber A are communicated with each other on a part of the outer circumference of the separator 6 (both left and right sides). Communicating portions are formed between the support frame 5 and the cylindrical body 2 to allow them to move.

In the cooking kiln 100A configured in this manner, the food material is, for example, pizza dough, and the cooking kiln 100A is used as a pizza kiln. The grate grate 4 is a charcoal grate for burning charcoal. In addition to charcoal, twigs may also be used as fuel in the fire bed grate 4 .

The base 1, tubular body 2, grate grate 4, support frame 5, upper lid 9, separator 6, cooking hearth 8, and inlet lid 10 are all made of refractory material. In this embodiment, the base 1, the tubular body 2, the support frame 5, the upper lid 9, the separator 6, the cooking hearth 8, and the inlet lid 10 are made of ceramics, and the grate rostle 4 is made of iron or the like. It is made of metal or ceramics. Here, the base 1 and the cylindrical body 2 are refractory heat insulating materials. The support frame 5 and the top cover 9 are refractory heat storage materials.

The inlet lid 10, the cooking hearth 8 and the separator 6 may be made of either a refractory heat insulating material or a refractory heat storage material.

(action, effect)
In the cooking kiln 100A configured in this way, when charcoal is burned in the combustion chamber A, the temperature of the combustion chamber A rises, and the heat of the combustion chamber A is transmitted to the baking chamber B, and the temperature of the baking chamber B increases. Rise. As a result, heat is accumulated in the upper lid 9 and the support frame 5 . At that time, the cooking hearth 8 is taken out from the inlet 15. - 特許庁Therefore, the heat energy from the combustion chamber A can be efficiently supplied to the upper lid 9, so that the heat storage time in the upper lid 9 can be shortened. Further, if the cooking hearth 8 is put out from the inlet 15, additional charcoal or the like can be put into the combustion chamber A from the inlet 15 through the communicating portion between the separator 6 and the support frame 5. Yes, it can be used continuously for a long time. Since charcoal alone or a mixture of charcoal and twigs is used as the fuel, the generation of smoke can be suppressed.

After the temperature rises to 350° C. to 400° C. in this manner, the cooking hearth 8 is placed inside from the inlet 15 and the cooking hearth 8 is heated. At that time, the heat of the combustion chamber heats the cooking hearth 8 through the separator 6 . Therefore, since an excessive temperature rise of the cooking hearth 8 can be suppressed, the upper lid 9 and the cooking hearth 8 can be heated appropriately. Next, after the pizza dough is put on the cooking hearth 8 from the inlet 15, the inlet 15 is closed by the inlet cover 10, and the pizza dough is baked. As a result, the pizza dough is properly baked by the heat conducted from the cooking hearth 8 and the radiant heat from the top lid 9 . At that time, if the pizza dough is placed on the attached auxiliary net 7, the baking work is easier, and the occurrence of scorching can be suppressed more than when the pizza dough is directly placed on the cooking hearth 8. can. Further, by opening/closing and adjusting the degree of opening of the inlet cover 10 and the vent cover 3 to control the temperature, the pizza dough can be baked at an appropriate temperature. More specifically, the vent 16 is an oxygen supply port to the combustion chamber A, and the temperature can be adjusted by controlling the degree of opening of the vent 16 with the vent cover 3 . Also, the inlet 15 of the baking chamber B can be opened and closed by the inlet cover 10 . Therefore, when too much energy is supplied to the combustion chamber A, the temperature can be controlled by, for example, closing the vent cover 3 and opening the input port 15 . Also, when the temperature of the baking chamber B is increased or when the baking chamber B is not in use, energy loss can be reduced by closing the inlet 15 with the inlet cover 10 .

Further, in this embodiment, since the separator 6 is arranged between the combustion chamber A and the cooking hearth 8, the heat energy from the combustion chamber A to the cooking hearth 8 can be controlled. More specifically, since the separator 6 is shorter in the horizontal direction than the support frame 5, wide communication portions are formed on both the left and right sides of the separator 6, so that the temperature rise of the cooking hearth 8 can be suppressed. , the transmission of thermal energy to the baking chamber B can be dispersed on both the left and right sides, and uniform heat accumulation in the upper lid 9 can be realized. Therefore, the temperature rise and temperature distribution of the cooking hearth 8 can be controlled. Therefore, in the case of the conventional two-layer structure, according to this embodiment, it is possible to solve the problem that the baking on the top surface of the pizza dough is slow due to the radiation of far infrared rays. can be fired to

Further, the base 1 and the cylindrical body 2 are fire-resistant heat insulating materials, while the support frame 5 and the top lid 9 are fire-resistant heat storage materials. Here, the refractory heat insulating material has a smaller specific gravity than the refractory heat storage material. Therefore, the mass of the entire cooking kiln 100A can be made smaller than when the base 1, the cylindrical body 2, the support frame 5, and the upper lid 9 are all made of refractory heat storage material. is easy to assemble and transport. In addition, since the temperature of the kiln rises in a shorter time than when the base 1, the tubular body 2, the support frame 5 and the upper lid 9 are all made of refractory heat storage material, the preparation time can be shortened. Easy to use.

In addition, since the upper lid 9 has an arched shape, the distances between the upper lid 9 and each position of the pizza dough can be made uniform. Further, since the central portion 90 of the top plate portion of the upper lid 9 is made the thickest, the amount of heat stored in the central portion 90 of the top plate portion of the upper lid 9 can be increased. Therefore, it is possible to irradiate the pizza dough with far-infrared rays sufficiently and evenly.
