As a cooking utensil suitable for this type of cooking, an insulating cooking container shown in FIG. 6 has been conventionally provided.

This heat-insulating cooking container is composed of an outer container 1, an inner container 2 to which an inner container lid 2 a is attached, and a heat-insulating outer container lid 3. The outer container 1 has a double structure consisting of an outer bottle 4 and an inner bottle 5, and a heat insulating portion 6 filled with a vacuum or a heat insulating material is formed between the inner and outer bottles 4 and 5.

Outer container handles 7 projecting outward are attached to the outer sides of the opposing portions of the opening of the outer container 1, and a support for stably placing the outer container 1 on the outer bottom portion. The body 8 is attached by screws 8a.

Further, the inner container 2 is provided with a handle portion 11 of the container 2 including a handle handle 9 and a handle 10 attached to the tip. The base end of the handle handle 9 of the handle portion 11 is fixed to the outer peripheral surface of the inner container 2, extends upward, bends outward, and abuts on the edge 12 of the opening portion of the outer container 1, Extending above the handle 7 of the container 1, the handle 10 has almost the same height as the upper surface of the outer container lid 3 and is close to the outer container lid 3.

The inner container 2 is supported in the outer container 1 by suspending a handle 9 provided on the container 2 on an edge 12 of an opening of the outer container. Alternatively, the inner container 2 may be supported by bringing the outer bottom surface of the inner container into contact with the inner bottom surface of the outer container. In addition, 13 is a knob of the inner container lid 2a, and 14 is a recess formed in the lower surface of the outer container lid 3 for accommodating the knob 13.

[0010]

[Problems to be solved by the device]

 However, in the above-mentioned heat-insulated cooking container, the inside of the inner container cannot be observed with the inner container covered. In order to see the inside of the inner container during cooking with heat or adiabatic cooking, it is necessary to open the lid of the inner container or the lid of the outer container and the lid of the heat insulating container.

[0011] Especially when the lid is opened during adiabatic cooking, the temperature of the inner container is lowered, the adiabatic cooking function is significantly lowered, and there is a case where heating and cooking are required again.

As a result of various studies to solve the above problems, the present inventors have made the inner container lid transparent, and the water vapor generated from inside the inner container is condensed on the inner surface of the inner container lid, and the transparent As long as the inner container lid is not opened, only the outer container lid can be opened to observe the inside of the inner container, and if the outer container lid has a viewing window. It was thought that the heat loss could be reduced by observing the inside of the inner container through the transparent part of the outer container lid.

The present invention has been made based on the above idea, and provides a heat-insulating cooking container capable of observing the inside of the inner container without heat loss not only during heat cooking but also during heat insulating treatment. The purpose is to provide.

[0014]

[Means for Solving the Problems]

 In the heat-insulating cooking container according to the present invention, the heat-insulating outer container, the inner container having an inner container lid that is removably accommodated in the outer container, and the inner container with the lid accommodated are accommodated. In a heat-insulating cooking container comprising a heat-insulating outer container lid that closes the opening of the outer container, the inner container lid that closes the opening of the inner container has a convex shape that gradually descends from the center toward the periphery, or The problem-solving means was that the heat-resistant transparent body had a concave shape that gradually fell from the periphery toward the center, and consisted of a part of a substantially spherical surface. By forming a metal deposition film or a heat shield plate on the inner surface of the inner container lid made of the above heat-resistant transparent body while leaving a part of the transparent portion, the inside can be seen and heat loss due to radiation can be suppressed. You can Furthermore, if a viewing window is formed in a predetermined portion of the heat insulating outer container lid, the inside of the inner container can be observed through the inner container lid.

[0015]

[Action]

 Since the heat-insulating cooking container according to the present invention has the above-mentioned configuration, the water vapor generated from the inside of the inner container is condensed on the inner surface of the inner container lid, and the transparency of the lid is lost, but the inner surface of the lid is at the central portion. From the outer periphery to the outer periphery or from the outer periphery to the center, the condensed water flows along the inner surface of the inner container lid, flows into the inner container, and the inner surface of the lid becomes cloudy. Are removed and remain almost transparent. Therefore, if only the outer container lid is opened, the inside of the inner container can be observed through the lid of the inner container. If the outer container lid is provided with a transparent part, the inside of the inner container can be observed without opening the lid of the inner and outer containers.
