Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the disclosure of a rice cooker having a new pot structure and an inner pot made of a heat storage composite plate.

Therefore, in conventional pots of this type, the inner pot was constructed from a single aluminum plate, and the heating section of the outer pot was connected to the non-heating section by heat and electricity. The temperature difference between parts was significant, and even when cooking a large amount of rice, it was easy for some parts to burn.

Furthermore, since the inner metal is made of aluminum, it is easily scratched, and dirt and the like can easily stick to the scratched parts.

The present invention was devised especially in view of the inconveniences in the prior art, and one of its main objectives is to ensure that the upper and lower parts of the inner pot are at the same temperature; This prevents the rice from being unevenly cooked and burnt.

Furthermore, the present invention increases the amount of heat stored in the inner pot so that the rice can be cooked fluffy to the core.

One of the other main objects of the present invention is to make the inner and outer pots resistant to abrasion and less susceptible to scratches by forming stainless steel surfaces on the inner and outer surfaces.

Therefore, in order to achieve an appropriate and appropriate effect on the above characteristics, the present invention provides an inner pot that directly accommodates cooked rice, and an outer pot that accommodates and reheats the inner pot. In a rice cooker consisting of a pot, if the inner pot is made of a heat-storage composite plate made by alternately laminating stainless steel plates and aluminum plates with different thermal conductivities, then 1.
Considerable design changes are planned for uIL.

The details of the invention will now be described with reference to a typical embodiment shown in the drawings. (1) is an outer pot of an electric rice cooker, and a heating device (1) is provided at the bottom of the inner wall of the outer pot (1). 2) is buried;
An inner pot (3) for storing cooked rice is fitted into a visible outer pot (1). The inner pot (3) is made of 304 stainless steel plate (3) for the front and back layers, and 1145 stainless steel plate (3) for the middle layer.
, aluminum film (3)b.

Another typical embodiment of the present invention is as shown in FIG.
Aluminum board (3) c, 1145 aluminum plate (3
)b, 304 stainless steel &ff1(3)a.

The present invention provides a rice cooker having a characteristic configuration as described in Section 1-1, in particular, an inner pot for accommodating directly cooked rice, and an outer pot for storing and heating this inner pot. The deficiencies of the prior art described above can be effectively corrected by consisting of a heat storage composite layer in which stainless steel plates and aluminum plates with different conductivities are laminated in an alternating V pattern, and the following specific effects are achieved. This is what I was able to play.

That is, the present invention transmits the heating temperature of the outer pot (1) lower shell to the outermost stainless steel layer of the inner pot (3), and the next aluminum layer due to the good thermal conductivity of the aluminum. When the heat is applied to the entire aluminum layer, it is transmitted to the next stainless steel layer approximately evenly, /1j, and then the heat is transmitted to the next stainless steel layer at various locations on the inner wall of the inner pot. Make it smaller and partial 10. If you change the height to VJ + I, you can reduce heat loss! 'H! , <The cooking effect is 9jj.

In addition, in the present invention, the inner pot has a multilayer structure.
Due to its large size, the conductivity of the rice to the rice is also high, which guarantees a fluffy and fluffy rice that can be cooked to the core.

Furthermore, in the present invention, the surface of the inner pot (3) is made of stainless steel, and due to the hardness of this stainless steel, it is resistant to wear and does not easily get scratched, and has a glossy appearance, which improves the aesthetic appearance. It's also a matter of having sex.

Next, the present invention is applicable not only to steam rice cookers but also to inner pots of gas rice cookers, etc., and includes a heating device (2).
Regardless of the structure of the inner pot, it is guaranteed to conduct heat uniformly from each part within the inner pot, making it unnecessary to improve the heating device itself, and reducing costs.

As stated in Section 2, an object of the present invention is to provide a highly effective rice cooker in which the inner pot is made of a heat storage composite plate and which enables effective rice cooking.
