The cooking container 1 is directly heated by the combustion flame of the solid fuel 7, and is also heated by the infrared rays generated by heating the infrared radiator 8 by the combustion flame. Furthermore, since a large amount of infrared rays are radiated from the heated ceramic cooking container 1, the food to be cooked can be efficiently cooked in a short time, and in the case of a pottery dish, it is moderately browned and has an excellent taste. It will be baked to the ready state. In addition, since the irritating or odorous component in the combustion gas of the solid fuel 7 is decomposed by the action of infrared rays or is adsorbed by the porous infrared radiator 8 made of ceramic, it is used during cooking as in the conventional case. No more eye irritation and no unpleasant odor. Further, the flame rising from the solid fuel 7 is blocked by the infrared radiator 8 arranged above it and diffused in the outer peripheral direction of the cooking container 1, so that the entire bottom surface of the container is heated uniformly.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. The ceramic cooking container 1 shown in FIG. 1 is formed in a dish shape so as to be suitable for grilled meat dishes.
The cooking container 1 is made of zirconia-based, silicic acid-based, titania-based ceramic or the like, which has a property of easily emitting infrared rays, particularly far infrared rays, when heated. Reference numeral 2 denotes a container stand that supports the cooking container 1 at a required height position, and is formed into a cylindrical container shape whose diameter gradually increases toward the upper edge. The container base 2 is provided with a vent hole 3 which is an escape port for combustion flames at three locations in the upper circumferential direction, and a vent hole 4 for introducing combustion air is provided at a plurality of locations in the lower circumferential direction. .. Reference numeral 5 is a tray of the container base 2, and 6 is a fuel container for storing solid fuel, which will be described later, and is formed into a cylindrical container shape, which is placed at the center of the bottom surface of the container base 2. The container base 2, the tray 5 and the fuel container 6 are all made of pottery or porcelain.

A heating heating element for heating the cooking container 1 is constituted by combining a well-known solid fuel 7 formed in a short cylinder shape and a ceramic infrared radiator 8 arranged above the solid fuel 7. Has been done. The infrared radiator 8 of this embodiment is shaped like a small ball. Reference numeral 9 denotes a metal foil fuel case, which encloses the outer periphery of the solid fuel 7 except the upper surface portion.

The infrared radiator 8 is formed by molding and firing a ceramic material such as zirconia or silicic acid similar to the cooking container 1, and has a characteristic of emitting a large amount of infrared rays when heated. The infrared radiator 8 of this embodiment is formed into a porous ball shape having a diameter of about 10 mm.

Next, the operation of the above configuration will be described. For example, when cooking yakiniku in a guest room such as an inn, the container base 2 placed on the saucer 5 is placed on a table, the fuel container 6 containing the solid fuel 7 is installed at the bottom of the container base 2, and the upper surface of the solid fuel 7 is placed. When the ball-shaped infrared radiator 8 is placed in the receiving recess 7a, the cooking container 1 is ready to be heated. Therefore, when the cooking container 1 is placed on the container base 2 and the solid fuel 7 is ignited by using an ignition lighter or the like, as shown in FIG. 1, the flame a rising from the upper surface of the solid fuel 7 is The infrared radiator 8 in the shape of a ball placed on the center of the upper surface prevents the infrared radiator 8 from rising straight up, and the infrared radiator 8 is heated.
The light is deflected and diffused outward along the outer peripheral surface. Therefore, unlike the conventional case in which the infrared radiator 8 is not placed, the flame a does not intensively heat only the central portion of the bottom surface of the cooking container 1, and substantially the entire bottom surface of the container is heated.

The cooking container 1 is also efficiently heated by the infrared rays emitted from the infrared radiator 8 which is strongly heated by the flame a of the solid fuel 7. In addition, a large amount of infrared rays are emitted upward from the heated cooking container 1. Therefore, the meat placed on the cooking container 1 has an appropriate browning due to the conduction heat from the heated cooking container 1 and the internal heating action by the radiated infrared rays, and the taste is very good. It is quickly baked in a stable state. Therefore, if the solid fuel 7 is extinguished after cooking, a large amount of unburned residue remains even with the same amount of solid fuel as the conventional one. Therefore, when it is desired to reheat the food in the cooking container 1 after a while, it is only necessary to reignite the solid fuel 7 without having to bother the waiter to replace the solid fuel.

In addition, the irritating substances and odorous substances contained in the combustion gas of the solid fuel 7 are also irradiated with infrared rays to be thermally decomposed, or are made of ceramics and have a porous infrared radiator 8.
Most of it is lost after being adsorbed by and decomposed by heating.

FIG. 3 shows a second embodiment of the present invention. The difference from the first embodiment is that a cylindrical support member 10 made of a heat-resistant material is embedded in the solid fuel 7 and the infrared radiator 8 is placed on the support member 10. It is in. In this way, even if the upper surface of the solid fuel 7 is gradually lowered along with the combustion of the solid fuel 7, the infrared radiator 8 does not descend, and the distance from the bottom surface of the cooking container 1 is the desired distance at the beginning of combustion. Kept in. Therefore, the infrared radiator 8 as described above
The heating action of the cooking container 1 and the diffusion action of the flame are
Stay in the best condition.

FIG. 4 shows a third embodiment of the present invention. The difference from the first and second embodiments is that the infrared radiator 8
Is not directly placed on the solid fuel 7, but the support member 11 for the solid fuel 7 is prepared separately. The support member includes a ring 11a on which the ball-shaped solid fuel 7 is mounted, a tripod 11
It has a form like "Gotoku" supported by b. The support member 11 is taller than the solid fuel 7 when it is fitted in the fuel case 6. The operation of the support member 11 is substantially the same as that of the support member 10. In this case, since the infrared radiator 8 does not come into direct contact with the solid fuel 7, it is not contaminated by combustion residues, and therefore the infrared radiator 8 can be used repeatedly as many times as desired.

FIG. 5 shows a fourth embodiment of the present invention. The difference from each of the above-mentioned embodiments is that the infrared radiator 8A is formed into a plate shape having a substantially triangular shape instead of a ball shape, and the infrared radiator 8A is mounted on the upper edge of the fuel container 6 and used. It's right there. A flame opening 8a is provided in the center of the infrared radiator 8A.
