Description

The present invention relates to a heat energy efficient cooking pan composed of inner and outer double pans, and in particular, a heat storage member is coupled to the bottom surface of the inner pan, and the tip of the partition wall standing plate of the heat storage member and the bottom surface of the inner pan are brought into contact with each other. The present invention relates to a thermal energy efficient cooking pan composed of an inner and outer double pan that forms a space between the bottom surface of the inner pan and the heat storage member by a plate and extends heating and heat retention time.

Many of the heat-insulated cooking pans and energy-saving pans currently on the market have a certain degree of energy-saving effect.
The heat-insulating cooking pot and the energy-saving pot are composed of an outer pot having heat insulation and heat-retaining functions, and an inner pot accommodated in the outer pot.
During use, the inner pot is heated to boil the food inside, then the inner pot is moved into the outer pot, and the heat in the outer pot heats and heats the food in the inner pot with residual heat to cook for a long time. Insulation performance can be achieved.
However, these products have the disadvantage that the use efficiency of heat energy is not sufficient in the course of use, and that the time for cooking after heating is not long after leaving the heat by direct fire.

Therefore, an energy-saving pan that improved the above-mentioned drawbacks was developed.
The energy-saving pan is fixed in such a manner that several fixed pieces or fixed blocks are installed in an annular shape at the bottom of the inner pot, and a heat storage ring is applied to the lower portion of the fixed pieces or the fixed blocks.
This keeps the distance between the heat storage ring and the bottom of the inner pot, and when the food in the pot starts boiling when the inner pot is heated, the heat storage ring is heated at the same time, and the heat storage ring is 500-600 ° C It becomes extremely hot.
After moving the inner pot into the outer pot, the heat storage ring acts as a "sustained warming" on the inner pot, which speeds up the cooking of food and shortens the time to completion of cooking. At the same time, the amount of fuel used can be reduced.

Although the above-mentioned energy-saving pan has certainly advanced as compared with the conventional heat-insulating cooking pan, there are still the following drawbacks.
1. The heat storage ring overhangs on the bottom of the inner pan and an open space is provided between the heat storage ring and the bottom of the inner pan, so that heat easily dissipates from the open space to the outside during heating. The heat storage ring cannot be heated more quickly.
2.Since the heat storage ring is in an overhang state, when the heat storage ring continuously heats the inner pot, heat is applied to the bottom surface of the inner pot due to the heat conduction of the fixed piece or fixing block installed in an annular shape. Do warm. Therefore, the amount of heat tends to concentrate excessively, and the problem of food scorching tends to occur.
3.When the heat storage ring dissipates heat, the amount of heat is mainly transferred upward through the fixed piece or fixed block, but most of it is in the air between the bottom of the inner pan and the inner bottom of the outer pan. Because it dissipates, if the space and the outside of the outer pan are not completely in close contact with each other, the amount of heat is quickly dissipated, reducing the heat retention effect.
This invention is made | formed in view of the fault mentioned above of the conventional energy-saving pan.

The best mode for carrying out the present invention will be described below in detail with reference to the drawings.
As shown in FIGS. 1 and 2, a heat energy efficiency cooking pan 1 composed of an inner and outer double pan of the present invention comprises an outer pan 2, an inner pan 3, and a heat storage member 4.

The inner and outer pots 3 and 2 each have a cylindrical shape, and an inner pot accommodating installation space 21 is formed inside the outer pot 2.
Since the outer diameter of the inner pot 3 is slightly smaller than the inner diameter of the outer pot 2, the inner pot 3 can be accommodated in the accommodating installation space 21 of the outer pot 2.

The heat storage member 4 has a substantially circular circular bottom plate 41 made of a solid metal plate whose outer diameter is slightly smaller than the outer diameter of the inner pot 3, and the partition wall-like standing plate 42 extends upward from the periphery of the upper surface of the bottom plate 41. Stretch to.
