Description

[Detailed description of the invention] This invention relates to a cooking pot that has a heat siphon function, which heats the bottom of the pot and effectively transfers heat upward to the sides, thereby ensuring uniform heating of food. be.

In order to obtain good rice cooking similar to that of Hagama, which is said to be able to cook delicious rice, it is necessary to heat the pot containing the rice evenly.

However, regular rice cookers use an electric heater or gas flame to heat the bottom of the pot to cook rice, which has the disadvantage that the temperature at the bottom of the pot is higher than the sides, making it difficult to cook the rice evenly. there were.

In order to improve this drawback, the pot is made into a double-walled structure with multiple voids at the bottom and sides, and a working fluid is sealed in the voids. Attempts have been made to heat it from

However, even in this pot, as shown in FIGS. 1 and 2, a plurality of voids 2 filled with hydraulic fluid 3 are vertically provided on the sides of the pot 1, so that the gap 4 between the voids 2 and 2 is Part is void 2
, the temperature is lower than that of the part with 2, and for this reason the temperature of the pot 1
However, the strength of the water differs from that of the water inside, and the disadvantage is that the expected uniform heating cannot always be achieved.

Of course, narrowing the gap 4 between the adjacent gaps 2 will improve the temperature uniformity effect to some extent, but this poses problems such as weakening the strength of the pot itself and requiring an increase in the amount of expensive working fluid, making it difficult to implement. Ta.

The present invention improves the above-mentioned drawbacks and heats the pot evenly and evenly.

One embodiment of this will be explained below with reference to Fig. 3. Reference numeral 1 is a pot used for cooking rice and other cooking, which has a double-walled structure similar to those shown in Figs. 1 and 2; A plurality of voids 2 are formed between the heavy walls, one end of which is located at the bottom and the other end extends upward from the side, and a hydraulic fluid 3 shown in FIG. 2 is sealed within the voids 2.

In the present invention, the side gaps 2 are particularly inclined in the same direction, and the upper and lower portions of adjacent gaps 2 and 2 overlap each other in the vertical direction.

Since the present invention has the above configuration, the convection 5 generated by heating the side of the pot 1 is generated vertically upward, so this convection 5 flows while intersecting the adjacent gap 2, and the gap 2
This is to equalize the temperature of the gap 4 between the two.

Further, while the side portions of the pot become uniform in temperature, the convection currents 5 are accelerated each time they cross each gap 4, and the uniform temperature of the rice, etc. in the pot 1 is further improved.

The inclination angle Q of the gap 2 is experimentally determined to be 30° to 80° from the viewpoint of ease of return of the working fluid 3 in a gravitational field.

As mentioned above, with the cooking pot according to the present invention, the entire pot is heated almost uniformly, and the convection is strong, so the temperature inside the pot is uniform and the rice is cooked evenly and well, similar to hagama rice cooking. It has the advantage of being able to cook other foods.

[Brief explanation of the drawing]

Fig. 1 is a perspective view of a conventional cooking pot with a heat siphon function, Fig. 2 is a sectional view taken along line A-A in Fig. 1, and Fig. 3 is a perspective view of a cooking pot with a heat siphon function according to the present invention. It is. In the figure, 1 is a cooking pot, 2 is a gap, and 3 is a working fluid.

Claims (1)

[Scope of utility model registration request] A cooking pot having a double-walled structure, forming a plurality of gaps between the double walls, one end of which is located at the bottom and the other end extending upward from the side, and a working fluid is sealed in the gaps.
