Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the disclosure of a rice cooker having a new pot structure, particularly 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 partially heated by heat and electricity from the non-heating section. The difference in temperature was significant, and even when a large amount of rice was cooked, it was easy to cause partial burns.

In addition, since the inner pot is made of aluminum, it is easily scratched and has the disadvantage that dirt and the like tend to adhere to the scratched portions.

The present invention was devised especially in view of the inconveniences in the prior art, and one of its main purposes is to ensure that the upper and lower parts of the inner pot are at the same temperature so that the rice can be cooked. This is to prevent uneven burning.

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

Furthermore, one of the other main objects of the present invention is that the inner and outer surfaces of the inner pot are made of stainless steel so that they are resistant to wear and less likely to be scratched.

Therefore, in order to achieve the appropriate and purposeful effects of the various characteristics, the present invention provides an inner pot that directly stores cooked rice, and an outer pot that houses and heats the inner pot. In this rice cooker, the inner pot will be made of a heat storage composite plate made by alternately laminating stainless steel plates and aluminum plates with different thermal conductivities, and considerable design changes are planned in accordance with the gist of the configuration. This is what I did.

The details of the present invention will be described below with reference to a typical embodiment shown in the drawings. Reference numeral 1 is an outer pot of an electric rice cooker, and a heating device 2 is embedded in the bottom of the inner wall of the outer pot 1. There is an inner pot 3 for storing cooked rice inside the outer pot 1.
It is designed to fit together. The inner pot 3 is
The front and back layers are 304 stainless steel plate 3a middle layer
It consists of three layers of 1145 aluminum plate 3b.

Another typical embodiment of the present invention is the third embodiment.
As shown in the figure, from the inner surface of the inner pot 3, 304 stainless steel plate 3a, 1145 aluminum plate 3b, 3004 aluminum plate 3c, 1145 aluminum plate 3b,
It is made of a composite plate consisting of a 304 stainless steel plate 3a.

The present invention has a characteristic structure as described above, in particular, a rice cooker consisting of an inner pot for storing directly cooked rice, and an outer pot for storing and heating this inner pot, in which the inner pot has a high thermal conductivity. The above-mentioned deficiencies of the previous example can be effectively corrected by using a heat storage composite plate made of alternately laminated stainless steel plates and aluminum plates of different types, and it has the following specific effects. That's what I got.

That is, in the present invention, the heating temperature from the lower part of the outer pot 1 is transmitted to the outermost stainless steel layer in the inner pot 3, and then the heat is quickly transferred to the entire aluminum layer due to the good thermal conductivity of the aluminum layer. transmitted,
The heat is transmitted to the next stainless steel layer with an almost uniform distribution, significantly reducing the temperature difference at each location on the inner wall of the inner pot.
This prevents partial burning, reduces heat loss, and allows for faster cooking.

In addition, in the present invention, the inner pot has a multi-layered structure and has a large amount of heat storage, so that the heat conductivity to the rice is high, and the rice is cooked to the core and fluffy.

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 scratches, and also has a glossy appearance and an aesthetic appearance. It could have been done.

Next, the present invention is applicable not only to electric rice cookers but also to inner pots of gas rice cookers, etc., and regardless of the structure of the heating device 2, each part of the inner pot receives uniform heat. It promises good conductivity, eliminates the need for improvements to the heating device itself, and is expected to reduce costs.

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