As shown in FIG. 9, the ceramic cooking kiln 10 having a structure according to the present embodiment is housed by the outer peripheral edge portion 64 of the lid 20 coming into contact with the upper opening 18 of the accommodating portion 12. A bottom container 14 whose portion 12 is covered with a lid 20 is placed on a gas stove 72 which is a heat source. In such a state, a heating chamber 74 is defined between the accommodating portion 12 of the bottom container 14 and the lid 20, and the cooking plate 16 is accommodating and arranged on the accommodating portion 12 with a gap 52 in between. ing. Since the bottom container 14 is provided with the through hole 32, the inside of the heating chamber 74 is exposed to the flame 76 of the gas stove 72 through the through hole 32, and oven cooking is possible. Here, since a plurality of through holes 32 are formed in the bottom wall portion 24 of the bottom container 14 in a state of being evenly arranged in the circumferential direction, the bottom container is provided with heat from the heat source in a well-balanced manner in the heating chamber 74. The rigidity of the bottom wall portion 24 of the 14 can be advantageously secured, and the durability can be improved. As the heat source, any heat source such as a charcoal fire or an electric heater can be used in addition to the gas stove 72 exemplified in the present embodiment. In addition, a plurality of concave grooves 62 are formed on the back surface 60 of the lid body 20, which is the image plane that defines the heating chamber 74. Further, in order to facilitate understanding, in FIGS. 9 to 10, the flame 76 is shown by a virtual line.

When cooking in the oven, the heating chamber 74 is usually preheated before cooking. In such a preheating step, as shown in FIG. 10, the upper opening 18 of the accommodating portion 12 is covered with the lid 20 without accommodating and arranging the cooking plate 16 in the heating chamber 74. Is placed on the Gotoku 78 of the gas stove 72, which is a heat source. The trivet 78 is provided with radial support plates 80 having a substantially inverted L-shape in a side view, which are evenly arranged at six locations in the circumferential direction (not shown). Twelve radial support portions 36 extending from the central portion 34 toward the outer peripheral edge portion 22 are evenly arranged in the circumferential direction on the bottom wall portion 24 of the bottom container 14, and the back surface of each radial support portion 36 is arranged. Is provided with a concave groove 38 that opens downward. Therefore, when the bottom container 14 is placed on the trivet 78, the bottom container 14 is provided on the back surface of the 12 radial support portions 36 of the bottom container 14 by simply rotating the bottom container 14 in the circumferential direction on the trivet 78. The upper end of the radial support plate 80 of the trivet 78 can be quickly accommodated and arranged in any of the concave grooves 38, and the bottom container 14 can be easily and stably positioned on the trivet 78. Further, as a result, the annular protrusions 44 provided on the back surface of the 12 annular portions 40 of the bottom container 14 can be accommodated and arranged on the inner peripheral side of the protruding end portion of the radial support plate 80 constituting the trivet 78. , The bottom container 14 can be positioned more stably on the trivet 78.

As shown in FIG. 9, the gas burner 82 of the gas stove 72, which is a heat source, is arranged inside the trivet 78. An accommodating hole 84 is provided in the central portion of such a gas burner 82, and the temperature sensor 86 as a temperature detecting device is accommodated in the accommodating hole 84 in a state of being movable in the vertical direction. There is. The tip surface of the temperature sensor 86 is a detection unit 88, and the detection unit 88 has a known structure for detecting the temperature of the object to be detected by coming into contact with the object to be detected. Further, the compression coil spring 90 is accommodated in the accommodating hole 84. Then, the temperature sensor 86 is engaged with the upper end surface of the compression coil spring 90 in the accommodating hole 84, and the detection unit 88 is projected upward from the upper end portion of the radial support plate 80 constituting the trivet 78 (a state in which the temperature sensor 86 is engaged with the upper end surface of the compression coil spring 90. (Shown by virtual lines in FIG. 9). As a result, when the bottom container 14 of the pottery cooking kiln 10 is placed on the trivet 78 of the gas stove 72, the detection unit 88 of the temperature sensor 86 makes the bottom container based on the urging force of the compression coil spring 90. The bottom wall portion 24 of the 14 bottom wall portion 24 is pressed against the back surface of the central portion 34. Although not shown, the gas stove 72 has a built-in controller that adjusts the thermal power of the flame 76 of the gas burner 82 based on the temperature detected by the temperature sensor 86.

In the pottery cooking kiln 10 of the present embodiment, a substantially truncated cone-shaped protrusion 42 is projected downward from the back surface of the central portion 34 of the bottom wall portion 24 of the bottom container 14. The protruding end surface (lower surface) of the protruding portion 42 is a pressing surface 92 made of a circular flat surface. Therefore, when the bottom container 14 of the pottery cooking kiln 10 is placed on the trivet 78 of the gas stove 72, the entire surface of the pressing surface 92 of the protrusion 42 comes into contact with the detection unit 88 of the temperature sensor 86. , The temperature of the pottery cooking kiln 10 heated by the flame 76 of the gas burner 82 is detected by the temperature sensor 86. Further, when the bottom container 14 of the pottery cooking kiln 10 is placed on the trivet 78 of the gas stove 72, the protrusion 42 makes the temperature sensor 86 resist the urging force of the compression coil spring 90. Push down from the back surface of the bottom container 14. Then, the detection unit 88 of the temperature sensor 86 is separated from the back surface of the bottom container 14 by the amount corresponding to the protrusion height dimension: h from the back surface of the protrusion 42. At this time, the detection unit 88 of the temperature sensor 86 is arranged from the upper side of the flame 76 of the gas burner 82 having a relatively high temperature to the flame port side of the gas burner 82 having a lower temperature. As a result, the detection unit 88 of the temperature sensor 86 is less likely to be affected by the heat of the gas burner 82, and the detection unit 88 makes it difficult for the temperature inside the bottom container 14 and the heating chamber 74 of the pottery cooking kiln 10 to rise. It is possible to prevent the detection temperature from becoming abnormally high, and it is possible to effectively optimize the detection temperature by the detection unit 88.

In this way, in the preheating stage, as shown in FIG. 10, the upper opening 18 of the accommodating portion 12 is covered with the lid 20 without accommodating and arranging the cooking plate 16 in the heating chamber 74. The bottom container 14 is heated while being placed on the trivet 78 of the gas stove 72, which is a heat source. Since the cooking plate 16 is not housed and arranged in the heating chamber 74 in the preheating stage, there is no shield between the gas stove 72 and the lid 20, and the heating of the lid 20 can be promoted. Moreover, since a plurality of concave grooves 62 extending along the circumferential direction of the outer peripheral edge portion 64 of the lid 20 are formed on the back surface 60 which is the drawing surface of the heating cabinet 74 of the lid 20, the heating cabinet 20 is formed. The surface area of the back surface 60, which is the drawing surface of 74, can be increased, and the heat storage property of the lid body 20 is improved.

Next, as shown in FIG. 9, after the lid 20 is sufficiently heated, the cooking plate 16 on which the pizza 70 to be cooked is placed is housed and arranged in the heating chamber 74, and the pottery is continued. By heating the cooking kiln 10 using the gas stove 72, the pizza 70 on the cooking plate 16 can be cooked. During such heating, the back surface 60, which is the image plane of the heating chamber 74 of the lid 20, is preheated, so that radiant heat from the back surface 60 of the lid 20 is stably generated from the beginning of the heating. Therefore, the soaking of heat in the heating chamber 74 is advantageously achieved. Further, although the cooking plate 16 is housed and arranged in the heating chamber 74 during cooking, a gap 52 is formed between the cooking plate 16 and the bottom container 14. As a result, since the inside of the heating chamber 74 is directly exposed to the flame 76 of the gas stove 72 through the gap 52 and the through hole 32 provided in the bottom container 14, the heated state inside the heating chamber 74 can be advantageously maintained. At the same time, excessive heating of the cooking plate 16 can be suppressed to prevent undesired scorching of the pizza 70 to be cooked. Although the cooking plate 16 is not preheated, it is closer to the gas stove 72 than the lid 20 and is directly exposed to the flame 76 of the gas stove 72, so that the heat is quickly equalized to the preheated lid 20. ing.

Further, a plurality of concave grooves 62 are provided concentrically around the central portion of the back surface 60 of the lid body 20. Therefore, a plurality of heated air flowing diagonally upward and inward from the gap between the outer peripheral edge portion 22 of the bottom container 14 and the outer peripheral edge portion 46 of the cooking plate 16 are orthogonal to the flow direction of the air. Can be advantageously brought into contact with the recessed groove 62 of the lid 20 and can advantageously accelerate the heating of the lid 20. That is, as shown in FIGS. 4 and 9, such heated air enters the concave groove 62 along the arcuate inclined surface 68 constituting the concave groove 62 and hits the opposite vertical surface 66 afterwards. Since it spreads along the concave groove 62, the heating of the lid 20 can be advantageously promoted.

In addition, as shown in FIG. 9, the outer peripheral edge portion 46 of the cooking plate 16 is inclined more steeply than the outer peripheral edge portion 22 of the bottom container 14 which is positioned so as to face each other in the radial direction. As a result, a large gap between the outer peripheral edge portion 46 of the cooking plate 16 and the outer peripheral edge portion 22 of the bottom container 14 can be secured, so that the heated air can easily flow to the upper side of the cooking plate 16 through the gap. Further, the contact position of the outer peripheral edge portion 64 of the lid 20 with respect to the outer peripheral edge portion 22 of the bottom container 14 is outside the outer peripheral edge portion 46 of the cooking plate 16 in the radial direction (left-right direction in FIG. 9) and It is higher than the outer peripheral edge portion 46 of the cooking plate 16 in the axial direction (vertical direction in FIG. 9). Thereby, the heating chamber 74 can be widely secured in the radial direction and the axial direction.

According to the pottery cooking kiln 10 having a configuration according to the present invention, an arbitrary heat source such as a gas stove 72, a charcoal fire, or an electric heater is not required as in the conventional structure. Simply placing the bottom container 14 on the heat source makes it possible to enjoy cooking in the oven. Moreover, since the bottom container 14, the cooking plate 16, and the lid 20 are all made of earthenware, far-infrared rays are radiated at high density into the heating chamber 74 by heating them. Therefore, it is possible to advantageously realize delicious oven cooking in which heat is transferred to the core of the pizza 70. Further, since the bottom container 14, the cooking plate 16 and the lid 20 are all made of earthenware, it is possible to advantageously achieve heat equalization in the heating chamber 74 due to the heat storage property of the earthenware.

Although one embodiment of the present invention has been described above, this is merely an example, and the present invention is not to be interpreted in a limited manner by the specific description in the embodiment.

For example, in the above embodiment, in the bottom wall portion 24 constituting the bottom container 14, 12 radial support portions 36 are formed by the non-formed portions in which the through holes 32 are not formed, but 24 radial support portions 36 are formed. The support portion 36 may be formed. As a result, when the bottom container 14 is placed on the Gotoku 78, the Gotoku 78 can be placed in any of the concave grooves 38 provided on the back surface of the 24 radial support portions 36 of the bottom container 14 with a smaller amount of rotation. The upper end portion of the radial support plate 80 can be quickly accommodated and arranged.

Further, in the above embodiment, the concave groove 62 provided on the back surface 60 of the lid body 20 is provided concentrically around the central portion of the back surface 60 of the lid body 20, but the shape is not limited to this. For example, it can be provided in any shape such as a zigzag shape, a wave shape, a radial shape, or a grid shape. Further, the cross-sectional shape of the concave groove 62 is not limited to the triangular cross-sectional shape exemplified in the above embodiment, and can be provided by any cross-sectional shape such as a rectangular cross-sectional shape or a semicircular cross-sectional shape.

In addition, the object to be cooked in the pottery cooking kiln 10 of the present embodiment is not limited to the pizza 70, but may be roast chicken, roast beef, or bread, which takes a long time to cook to the inside. You may.

In the above-described embodiment, the lid 20 is provided with one pressure relief hole 58, but as shown in FIG. 11, a plurality of pressure relief holes 58 (FIG. 11) are two, three, or four, or more. In 11, four) may be evenly arranged in the circumferential direction of the lid 20. As a result, the heat inside the heating chamber 74 can be further equalized.
