Description

[Detailed description of the invention] The present invention relates to cooking appliances such as rice cookers and warmers that are equipped with an outer lid and an inner lid, and in particular, when the outer lid is closed, the entire circumference of the inner lid is uniformly aligned with the upper edge of the container. The purpose of this invention is to provide a cooking device that can be brought into contact with

Generally, the outer lid and the inner lid are connected by fixing an inner lid mount that is rod-shaped and has a large-diameter locking part at the tip at the center of the outer lid, while the inner lid has an elastic locking part. This was accomplished by attaching an elastic body such as a bush or a packing having a hole into which the rod-like part loosely fits, and then fitting this elastic body to the inner lid fitting.

However, since the diameter of the hole in the elastic body is larger than the diameter of the rod-shaped part of the inner lid attachment, when the outer lid is opened upside down using one of the hinges, the center of the outer lid and the center of the inner lid are separated by the weight of the inner lid. If the outer lid is misaligned and the outer lid is closed, the entire circumference of the inner lid does not come into uniform contact with the upper end of the container, making it impossible to obtain a sealed state.

Particularly, in a heat insulator that does not include a heating element in the inner lid and heats the food in the container from the inner lid by conductive heat from the container, a part of the food cannot be kept at a constant temperature.

The present invention solves the drawbacks of the conventional cooking appliances mentioned above, and a heat insulator will be described below as an embodiment of the present invention with reference to the accompanying drawings.

In the figure, 1 is a cylindrical main body with a bottom, and an outer pot 3 is disposed inside thereof with a heat insulating material 2 interposed therebetween.

The outer pot 3 is suspended from the upper end of the main body 1 via a pot support 4.

5 is an inner pot detachably provided within the outer pot 3.

A heat-retaining heater 6 is attached to the outer periphery of the outer pot 3.

Reference numeral 7 denotes an outer cover pivotally attached to the upper end side of the main body 1, and a heat insulating material 8 is incorporated therein.

Reference numeral 9 denotes an inner cover fixture fixed to the lower surface of the outer cover 7, and is fixed to the center of the outer cover 7 on the opposite side of the pivot portion by a distance A.

This inner lid fitting 9 is rod-shaped, and has a large-diameter locking portion formed at its tip.

Reference numeral 10 denotes an elastic body such as a bush or a packing that elastically engages with the locking part of the inner lid attachment 9 and has a hole into which the rod-shaped part is inserted with a margin. 10 is fitted into a fitting hole formed at the center of the inner lid 11.

The inner cover 11 and the elastic body 10 are removably attached to the inner cover fitting 9.

Note that the above-mentioned dimension A is preferably approximately the difference between the diameter of the hole of the elastic body 10 and the diameter of the rod-shaped part of the inner lid fitting 9.

In the above configuration, when the outer cover 7 is opened, the inner cover 11
is shifted toward the pivot part due to its own weight, and the hole of the elastic body 10 and the rod-shaped part of the inner cover fitting 9 come into contact on the opposite side of the pivot part.

In this state, the center of the outer cover 7 and the center of the inner cover 11 coincide.

Therefore, when the outer lid 7 is closed, it contacts the upper end of the outer pot 3 uniformly over the entire circumference of the inner lid 11, and heat is evenly transferred from the heat-retaining heater 6 to the inner lid 11 via the outer pot 3. It will be done.

Although the above embodiment has been described with respect to a heat insulator, it can also be applied to a cooking device such as a rice cooker in which it is desired that the contact between the container and the inner lid be uniform over the entire circumference.

As is clear from the above description, in the cooking device of the present invention, the inner lid mount is fixed by shifting it from the center of the outer lid to the opposite side of the pivot, and the hole of the elastic body is arranged at the center of the inner lid. Since the inner lid fitting is inserted into this hole with some allowance, when the outer lid is opened, the center of the outer lid always matches the center of the inner lid, and when the outer lid is closed, the center of the outer lid is always aligned with the center of the inner lid. Since the inner lid contacts the upper end uniformly over the entire circumference, the temperature difference between each part of the food to be cooked can be reduced.

Claims (1)

[Scope of utility model registration request] A container part provided on the side of the instrument body, an outer lid that covers the opening of the container part and is pivoted to one side of the main body, an inner lid fitting fixed to this outer lid, and an inner lid fitting attached to this inner lid fitting. It has an inner cover attached via an elastic body, the inner cover fixture is fixed at the opposite side of the pivot from the center of the outer cover, and the hole formed in the elastic body is placed at the center of the inner cover. Then, insert the inner lid fitting into this hole, and set the distance between the center of the outer lid and the center of the inner lid fitting to be approximately the difference between the diameter of the hole and the diameter of the inner lid fitting. vessel.
