Description

  The present invention relates to a technique for easily carrying a heating container that generates heat by microwaves in a microwave oven without burns.

  Conventionally, Patent Document 1 discloses a heating container used when heating an object to be heated in a microwave oven. In this technique, a ferrite film is formed on the outer surface of an aluminum container, and the ferrite film generates heat by microwaves to heat an object to be heated. This heat generating container can generate heat up to approximately 200 to 300 ° C. according to the film thickness of the ferrite film, and can efficiently heat an object to be heated in a short time.

  By the way, in the said technique, since a heat_generation | fever container becomes very high temperature, after heating, it was not able to carry if it did not cool down after time. Therefore, an outer container is provided so as to cover the outside of the exothermic container with an interval, and is insulated with an air layer between the containers so that it is difficult to transfer heat directly to the outer container. A double-structured heating container has been proposed that can be easily carried.

However, in the above technique, the air layer is formed in a substantially sealed space, and the heat of the air layer is transferred to the outer container and heated, so that it cannot be touched directly and there is still a risk of burns. . In addition, since the heat retention is enhanced by the air layer, the heat release of the outer container is slow, and it takes time to carry.

  The problem to be solved by the present invention is to solve these conventional problems and to provide a container for heating a microwave oven having excellent cooling properties that can be carried early after heating.

The configuration of the present invention that solves this problem is as follows.
1) A microwave heating container used when heating an object to be heated in a microwave oven, wherein the inner container that generates heat by microwave heating for placing the object to be heated overlaps the outer side of the inner container. The outer container is formed with a protruding piece on the outer edge of the upper end of the inner container, a step is formed on the inner edge of the outer container to hook the protruding piece of the inner container, and the outer container is made deeper than the inner container. To allow space to be formed between the containers during the stacking, to form a plateau on the lower surface of the outer container, to form a vent on the lower surface of the outer container, and to release air in the heated space after heating from the vent A container for heating a microwave oven characterized by enhancing the cooling performance of the outer container 2) A plurality of irregularities are formed in the stepped portion of the outer container, and the overhanging piece of the inner container and the outer container are stacked when the containers are stacked A ventilation gap is formed between It was possible manner, the 1) microwave heating container according.
It is in.

  According to the present invention, the heated air in the space is exhausted from the vent hole at the bottom of the outer container, so that the cooling performance is improved, and the outer container can be grasped and carried quickly without elapse of time.

  In the present invention, a plurality of projections and depressions are formed on the stepped portion of the outer container, a gap for ventilation is formed between the protruding piece of the inner container and the stepped portion of the outer container at the time of overlapping, and the contact area between the containers is increased. It is desirable to reduce the heat transfer to reduce the heat transfer and release the heated air between the containers from the gap to further improve the cooling performance. Embodiments of the present invention will be specifically described below with reference to the drawings.

  Example 1 shown in FIGS. 1 and 2 is an example in which the microwave heating container of the present invention is applied to a pan. FIG. 1 is a longitudinal sectional view of a container for heating a microwave oven according to the first embodiment, and FIG. 2 is a bottom view of the outer container according to the first embodiment.
