Abstract

[Problem] To provide a double-bottom earthenware pot that allows cooking not only with a cooker such as a stove but also with an IH type cooker. [Solution] A double-bottomed earthenware pot body 11 is formed by bonding a ceramic inner bottom 11a and a ceramic outer bottom 11b with an adhesive, and has spaces 11c and 11f divided by the inner and outer bottoms, and an earthenware pot. The pot lid 12 covers the top opening of the main body, and includes a bottom space 11c facing the bottom of the earthenware pot body, and a bottom space 11c extending from the bottom space to near the top opening of the earthenware pot body so as to face the side surface of the earthenware pot body. A side space 11f is formed, and a heat generating material 13 that self-heats by electromagnetic induction is inserted from the bottom space to the side space. The earthenware pot itself has a double bottom, so when cooking, the food on the inner bottom is not directly exposed to the fire of the stove. Foods are less likely to burn and have a high heat retention effect. [Selection diagram] Figure 1

Description

The present invention relates to an earthenware pot, and more particularly to an earthenware pot with a double bottom.

Japanese Utility Model Publication No. 51-84758 discloses a double-bottom earthenware pot having a space defined by an inner and outer bottom.
In such a double-bottom earthenware pot, the food on the inner bottom is not directly exposed to the fire of a stove or the like during cooking, so the food is less likely to burn. Furthermore, after cooking, the heat dissipation inside the clay pot is suppressed by the double-bottomed space, so it has a high heat retention effect.

By the way, IH (induction heating) type cookers have recently become widespread in homes. Since IH type cookers do not involve combustion, they do not pollute indoor air, are less likely to cause fires, and have the advantage of being able to easily control stable heating.
However, since IH type cookers utilize heat generated by electromagnetic induction, earthenware pots made of materials that are not conductive or magnetic cannot be used for cooking with IH type cookers.

Publication No. 51-84758

In view of these problems, the present invention aims to provide a double-bottomed earthenware pot that can be used for cooking not only with a cooker such as a stove but also with an IH cooker.

The present invention consists of an inner pot made of ceramic and an outer bottom made of pottery that are bonded together using an adhesive to form a double-bottomed clay pot body having a space defined by the inner bottom and the outer bottom, and an opening at the upper end of the clay pot body. An earthenware pot equipped with a pot lid that covers the pot,
The space includes a bottom space facing the bottom of the earthenware pot body, and a side space extending from the bottom space to the vicinity of the upper end opening of the earthenware pot body so as to face the side surface of the earthenware pot body;
It is characterized by inserting a heat-generating material that self-heats by electromagnetic induction from the bottom space to the side space.

Preferably, the heat generating material is inserted into the bottom space such that gaps are formed between the heat generating material and the inner sole and between the heat generating material and the outer sole.

According to the present invention, since the clay pot body has a double bottom, the food on the inner bottom is not directly exposed to the fire of a stove or the like during cooking. Therefore, the food is less likely to burn. Furthermore, after cooking, the heat dissipation inside the earthenware pot is suppressed by the double-bottomed space, resulting in a high heat retention effect.
In addition, a heat-generating material such as iron, silver, stainless steel, enamel, or carbon that generates heat by electromagnetic induction is placed in the double-bottomed space, making it possible to cook using an IH cooker.

FIG. 1 is a sectional view showing an earthenware pot according to a first embodiment of the present invention. FIG. 2 is a sectional view showing an earthenware pot according to a second embodiment of the present invention. FIG. 3 is a sectional view showing an earthenware pot according to a third embodiment of the present invention.

The present invention will be explained below based on the drawings. FIG. 1 shows an earthenware pot 10 according to a first embodiment of the present invention. This earthenware pot 10 includes an earthenware pot body 11 made of earthenware, and a pot lid 12 made of earthenware that covers the upper end opening of the earthenware pot body 11.

The earthenware pot body 11 has a double bottom structure in which a bottom space 11c and a side space 11f are formed, which are partitioned by an inner bottom 11a and an outer bottom 11b that is covered and bonded to the inner bottom 11a. The bottom space 11c faces the bottom surface of the earthenware pot body 11, and the side space 11f extends from the bottom space 11c to the vicinity of the upper end opening of the earthenware pot body 11 so as to face the side surface of the earthenware pot body 11. As an example, the outer sole 11b is adhered to the earthenware pot body 11 by covering the inner bottom 11a of the earthenware pot body 11, applying glaze and firing. Alternatively, it can also be bonded with a heat-resistant resin such as silicone. A stainless steel plate 13 is inserted as a heat generating material from the bottom space 11c to the side space. As the heat generating material, in addition to stainless steel, conductive or magnetic materials such as iron, silver, enamel, and carbon can be used.

An air vent hole 11d is formed in the outer sole 11b. A vacuum pump is connected to this air hole 11d to exhaust the air inside the space 11c, and the air hole 11d is closed with a plug 11e made of heat-resistant silicon or the like, thereby sealing the space 11c in a vacuum state. The outer bottom 11b is formed flat so that most of the earthenware pot body 11 is in close contact with the top plate of the IH cooker when it is placed on the top plate.

The structure of the earthenware pot 10 according to this embodiment is as described above, and since the earthenware pot body 11 has a double bottom, the food on the inner bottom 11a is not directly exposed to the fire of a stove or the like during cooking. Therefore, the food is less likely to burn. Further, after cooking, the heat dissipation inside the clay pot body 11 is suppressed by the double-bottomed bottom space 11c and side space 11f, so that a high heat retention effect can be achieved.

In addition, since stainless steel plates 13 that self-heat by electromagnetic induction are inserted into the bottom space 11c and side space 11f of the double bottom, cooking using an IH cooker becomes possible. Since the bottom space 11c and the side space 11f of the double bottom are evacuated and sealed, a high heat retention effect can be obtained.

FIG. 2 shows an earthenware pot 20 according to a second embodiment of the present invention. In the earthenware pot 10 according to the first embodiment, the bottom space 11c and the side space 11f at the bottom of the earthenware pot body 11 were evacuated, and the air vent hole 11d was closed with the stopper 11e to seal the bottom space 11c and the side space 11f. In the clay pot 20, the air vent hole 11d is left open without being blocked.
Note that the other configurations of the earthenware pot 20 according to this embodiment are the same as those of the earthenware pot 10 according to the first embodiment, so the same components are given the same reference numerals and the explanation will be omitted.

According to this embodiment, the air and high-pressure steam in the space 11c that are heated and expanded during cooking are exhausted to the outside through the air vent hole 11d, so it is possible to prevent the inner bottom 11a and the outer bottom 11b from bursting.

FIG. 3 shows an earthenware pot 30 according to a third embodiment of the present invention. Although the earthen pot 20 of the second embodiment has an air vent hole 11d, the earthen pot 30 according to this embodiment does not have the air vent hole 11d. Even if the air vent hole 11d is omitted, it is not necessarily necessary to provide the air vent hole 11d if the clay pot 30 is molded from a material with sufficient strength.
