Problems solved by technology

However, when the frame cover is made of a resin material, the size of the main body of the rice cooker changes due to expansion and contraction caused by heat during cooking, so that there is a problem that the locking mechanism of the lid cannot fully perform its function.
If the locking mechanism of the cover body is made to absorb the above-mentioned expansion and contraction, its structure will become complicated

Embodiment Construction

[0083] Next, the structure of the cooker 1 will be described. Cooker 1 is designed as an electric rice cooker.

[0084] The cooker 1 is a pressure cooker, and when cooking rice as cooking, the pressure in the pot is increased to, for example, 1.2 atmospheres to cook rice. As shown in Fig. 1 and Fig. 2, the cooker 1 has: a pot 2, which is composed of a deep-bottomed cylindrical container with an open top; It has a heating unit for heating the object to be cooked in the pot 2, and the lid body 14 can cover the openings of the pot 2 and the cooker main body 3, and can be opened and closed freely.

[0085] The pot 2 has a structure having an inner layer made of a material with high thermal conductivity such as copper or aluminum and an outer layer made of a magnetic material such as stainless steel, and the surface of the inner layer is covered with fluororesin or the like.

[0086] The cooker main body 3 has an opening of a size that can be inserted into the pot 2 on its upper ...

Abstract

A cooking device is provided to improve the mechanical stiffness and the heat resistance by forming at least any one side of a frame cover, an opening, and a cover of stiff metal material. A cooking device comprises a pot having a cylindrical container, an opening(6A) wherein the pot is placed, a main body(3) having a heating unit for cooking a material to be cooked inside the pot, and a cover(14). The cover, whose one end is supported by the main body and other end is engaged with the main body by a locking device, covers the opening of the pot and the main body. The periphery of the opening of the main body is covered by a frame cover(6). At least any one side of the frame cover and the cover is made of stiff metal material.

Description

technical field [0001] The invention relates to a cooker, in particular to a cooker structure of a pressure cooker which is suitable for raising the internal pressure of a pot for cooking. Background technique [0002] An electric rice cooker (hereinafter referred to as an electric rice cooker) is a kind of cooker. Electric rice cookers are widely used in general households, and various types of electric rice cookers have been developed and sold. There are types of rice cookers that cook rice by adjusting the pressure inside the pot to normal pressure when cooking rice, and those that cook rice by increasing the pressure to a predetermined pressure. [0003] In the latter type of rice cooker, when cooking rice, the cooked material (rice and water) in the pot is heated to a high temperature, and the pressure is increased to, for example, 1.2 atmospheres to cook rice. This type of pressure rice cooker has a pot for accommodating food to be cooked, a rice cooker body for acco...
