BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adiabatic cooking pot suitable for use in a cooking method in which a semi-cooked food is kept warm by heating or the like to obtain a cooked finished product. The inner lid is easy to take out even when heated.

[0002]

2. Description of the Related Art Generally, heating and processing of food is carried out by using electric heat or open flame. However, such a cooking method is apt to cause boiling and burning due to overheating, and consumes a large amount of energy. There was an inconvenience. As a cooking method that can eliminate this inconvenience, by dipping desired raw vegetables and grains in boiling water or boiling broth, and keeping the semi-cooked food in a cooked state for a long time, What is known is. As this type of heat-insulating cooking pan, there is one shown in FIG.

The heat-insulating cooking pot 30 shown in FIG. 2 is basically placed on the heat-insulating outer container 2, the inner pot 3 which is housed in the outer container 2 so that it can be freely taken in and out, and the inner pot 3. Inner lid 31
And a heat insulating outer lid 32 that closes the mouth opening of the outer container 2 with the inner pot 3 accommodated therein. A handle 33 is attached to the inner lid 31. This insulated cooking pot 30
Takes out the inner pot 3 and puts the cooking material into it, and heats it to the cooking temperature by heating it from the bottom and / or the side with an external heat source with or without the inner lid 31, and immediately with the inner lid 31 closed, If it is housed in the container 2 and the outer lid 32 is closed, the heat is prevented from being dissipated to the outside of the outer container 2, so that cooking proceeds without an external heat source.

[0004]

In the conventional heat-insulating cooking pot of this type, the outer lid 32 is opened and the inner lid 31 of the inner pot 3 is opened when the contents are observed in the middle of cooking or when the cooking is completed. The handle 33 arranged on the inner lid 31 is removed by manually grasping the handle 33.
Since it was heated to a high temperature inside and the surroundings were filled with high temperature hot air and kept warm, there were cases where it was not possible to immediately insert a hand and pinch the handle 33. The present invention has been made to solve this problem,
Therefore, the purpose thereof is to provide a heat-insulating cooking pot which retains heat-retaining property and allows the inner lid 31 to be immediately and safely removed from the inner pot 3 in an atmosphere heated to a high temperature by opening the outer lid 32. Especially.

[0005]

[Means for Solving the Problems] The above-mentioned problems are solved by an outer container having a heat insulating property, an inner pan which can be stored in and taken out from the outer container, an inner lid placed on the inner pan, and an inner lid. In a heat-insulating cooking pot having a heat-insulating outer lid that closes the mouth opening of the outer container in a state where the inner pot with the inside is accommodated, a handle is provided on the inner lid, and at least the upper end of this handle is The problem can be solved by providing an adiabatic cooking pot that is arranged such that the inner pot with a lid is housed in the outer container and projects upward from the mouth opening of the outer container. This handle is preferably made of synthetic resin. This heat-insulating outer container preferably has a heat-insulating layer which is a vacuum heat-insulating layer having a vacuum double-wall structure or contains a heat-insulating material.

[0006]

Since at least the upper end of the handle projects above the mouth opening of the outer container with the inner pot with the inner lid housed in the outer container, when the outer lid is opened, a high temperature atmosphere You can pinch the handle without inserting your hand inside.
Moreover, since this handle projects upward from the opening of the mouth of the outer container, the handle comes into contact with the outside air to cool rapidly, and can be immediately touched by hand.

FIG. 1 shows a preferred embodiment of the heat-insulating cooking pot of the present invention. In the following description, the same components as those of the conventional example described with reference to FIG. 2 are designated by the same reference numerals, and the description thereof will be omitted or simplified. In FIG. 1, the heat-insulating cooking pot 1 includes a heat-insulating outer container 2 having a vacuum heat-insulating layer having a vacuum double-wall structure, an inner pot 3 that can be stored in and taken out from the outer container 2, and an inner pot 3 thereof. Inner lid 4 placed on
And the outer container 2 with the inner pot 3 with the inner lid housed therein.
And a heat insulating outer lid 5 that closes the mouth opening 8 of the.

The inner lid 4 placed on the inner pot 3 is made of heat-resistant synthetic resin and is formed into a substantially spherical shape that is convex outward, and the peripheral edge portion is the edge portion of the mouth opening of the inner pot 3. The handle 6 made of synthetic resin is attached to the central portion of the inner lid 4 by a screw 7 inserted from the back side of the inner lid 4 and fixed. There is. Due to the spherical projection height of the inner lid 4 and the height of the handle 6 itself, the handle 6 is a state in which the inner pot 3 with the inner lid is sufficiently deeply accommodated in the outer container 2 to a fixed position. The upper end 6a of the outer container 2
It is arranged so as to project upward from the mouth opening 8 of the. Further, when the outer lid 5 is closed in this state, a recess 9 for accommodating at least the upper end portion 6a of the handle 6 is provided in a corresponding inner portion of the outer lid 5 so that the handle 6 does not come into contact with the inside of the outer lid 5.
Are formed.

In this heat-insulating cooking pot 1, the inner pot 3 is taken out, cooking ingredients are put therein, and the contents are heated to the cooking temperature by heating the bottom portion with an external heat source such as a stove with or without the inner lid 4. If the inner lid 4 is closed and immediately housed in the outer container 2 and the outer lid 5 is closed, heat is prevented from being dissipated from the outer container 2 to the outside, so that the cooking of the boil is continued without an external heat source. . When the inner lid 4 is opened for observing or taking out the contents of the inner pot 3 at the middle or the end of this adiabatic cooking, the upper end 6a of the handle projects above the mouth opening 8 of the outer container. Therefore, the handle 6 is quickly cooled by contact with the outside air, and the handle 6 can be immediately and safely pinched without exposing the hand to the high temperature atmosphere in the outer container 2.

In the outer container 2 of this embodiment, a bottomed cylindrical inner cylinder 10 made of a metal such as stainless steel and an outer cylinder 11 having a slightly larger diameter are joined and integrated at their mouths. The vacuum insulation container 12 has a vacuum double-wall structure in which air between the inner and outer cylinders 10 and 11 is exhausted and sealed from the bottom exhaust hole to form a vacuum insulation space layer, and a synthetic resin or the like attached to the bottom portion. It is composed of a bottom member 13. An outer container handle 14 made of synthetic resin or the like is attached to the outer edge of the mouth opening 8 of the vacuum heat insulating container 12.

The hinge mechanism 1 is attached to a part of the outer container handle 14.
5 is provided, and an outer lid 5 is swingably attached to this. A stopper mechanism 16 is provided on the outer container handle 14 on the side opposite to the hinge mechanism 15 to lock the outer lid 5 when the outer lid 5 is closed and to disengage the outer lid 5 by pushing it down when the outer lid 5 is opened. The outer lid 5 is filled with a heat insulating material 17 such as Styrofoam.

[0012] The inner pot 3 is a flat-bottomed pot having a cylindrical shape with a bottom used as a cooking pot, and has a smaller diameter in the vicinity of the opening of the mouth than that of the main body so that it can be conveniently accommodated in and taken out from the outer container 2. The rib 18 is formed on the outside of the rim portion and serves as a clue.

In the above-mentioned embodiment, the inner lid 4 is formed in a spherical shape convex to the outside, but the shape of the inner lid 4 is not limited to this, and the point is that at least the upper end portion 6 of the handle 6 is formed.
It suffices that a is configured to project upward from the mouth opening 8 of the outer container 2. Further, although the heat insulating outer container 2 has been described as having a vacuum heat insulating layer having a vacuum double wall structure in the above-mentioned embodiment, this heat insulating layer is not limited to the vacuum heat insulating layer, and the inner and outer cylinders 10, It is needless to say that the gap portion 11 may be filled with a foamed polyurethane heat insulating material or the like to form a heat insulating layer containing the heat insulating material.

[0014]
