Description

[Detailed description of the invention] This invention relates to a uniform heating container used as a cooking pot, a drying container, etc.

Conventional cooking pots do not have sufficient heat conductivity in the pot itself, so the heat applied from the microwave etc. at the bottom does not transfer smoothly to the periphery and top, making it difficult for non-liquid contents such as rice to In this case, there was a problem in that the heat was not distributed evenly throughout the contents, and although the contents could be cooked properly in the center of the pot, the contents were hard at the top and soft at the bottom.

This idea was made to solve the above problems, and by distributing heat evenly throughout the contents,
An object of the present invention is to provide an evenly heated container that can evenly heat this.

In order to achieve the above-mentioned purpose, the uniform heating container according to this invention has a container-like double wall inside and outside, the outer wall has many inward protrusions in contact with the inner wall, and both the inner and outer walls have inward protrusions. The heat transport medium is sealed in a closed gap formed in both the inner and outer walls, which are joined at the tip contact point of the part and the overlapping part of the upper end part.

Hereinafter, embodiments of this invention will be described in detail with reference to the drawings.

The uniformly heated container 1 according to this invention has a vessel-shaped inner and outer double wall 2,
Consists of 3.

The diameter and height of the container 1 are approximately 10 to 20 cm,
The distance between the inner and outer walls 2 and 3 is 2~5rIr! It is about n.

A large number of inward protrusions 4 are formed on the outer wall 3 and are in contact with the inner wall 2.

The shape of the inner protrusion 4 may be semi-circular in cross section as shown in FIG. 2 or conical with a flat top, but is not limited thereto.

In addition, the number and size of the inner protrusions 4 per unit area are as follows:
It differs depending on the relationship with the shape, etc., and is not uniquely determined.

Both the inner and outer walls 2.3 are the contact point 5 between the tip of the inner protrusion 4 and the inner wall 2.
and welded at the upper end overlap portion 6.

In this way, a sealed cavity 7 is formed between each non-joined portion of both the inner and outer walls 2, 3.

The cavity 7 is filled with a heat transport medium such as Freon or water.

The medium is introduced through a part of the non-welded portion of the upper end overlapping portion 7, and the non-welded portion is closed after introduction.

The heat transport medium receives heat from a microwave or the like at the bottom of the container, evaporates, and carries this heat from the peripheral side to the top.

The medium then radiates heat and condenses, flowing down to the bottom and gaining heat again.

Heat is thus transferred from the bottom to the periphery and top.

As described above, the heating container according to this invention has a vessel-like double wall inside and outside, and the heat transport medium is sealed in the airtight gap between both walls. The heat is carried by the same medium to the sides and to the top, so that the container itself is heated approximately evenly.

Therefore, according to the heating container of this invention, heat can be evenly applied not only to fluid contents but also to non-liquid contents such as rice, and cooking such as rice can be done with just the right amount of heat. It can be done.

In addition, the outer wall has many inward protrusions that touch the inner wall,
Since both the inner and outer walls are joined at the tip contact portion of the inner protrusion, the heating container has sufficient strength and has sufficient pressure resistance against the heat transport fluid. There is no problem of the same fluid gushing out due to breakage.
