Off-Fire Reboiling Pot

Ordinary cooking utensils are energy-wasteful, especially stewing pots. During preparation of foods such as rice, porridge, meat, soup or vegetables, the content of the pot is usually heated to boiling point and then allowed to stew or simmer on the stove for a considerably long time, using up fuel to do so. However, once boiling temperature is reached, the temperature within the pot does not actually rise beyond that. Instead, the energy wasted is used just to offset the heat lost (through evaporation, conduction, convection) in order to maintain the cooking pot at a sufficiently high temperature.

The present invention's aim is achieved by the following method: Beneath the metal bottom of the "daily thermal insulated energy-saving cooking utensil", a disc-shaped heat reservoir is installed, which is made of a special refractory material with excellent heat storage performance. When the utensil is placed on the stove being heated, the disc-shaped heat reservoir located beneath the utensil's bottom is heated up and starts to store heat energy, as the food in the utensil is heated up to boiling point, the heat reservoir has already stored a significant quantity of heat energy. Now the utensil can be taken away from the cooking stove and put on the thermal insulated base, the heat reservoir beneath the utensil's bottom will release its stored heat energy slowly. In the first tens of minutes, the pot can be maintained at boiling point temperature, while afterwards it can be maintained above 85℃ for several hours.

Therefore, by means of the above-mentioned design, this invention has achieved its aim through successfully appending the heat-regenerative performance to the "daily thermal insulated energy-saving cooking utensil" and thus making it has the special function to continuously heat up and turn raw or deficiently cooked food into thoroughly cooked food after the cooking utensil has been taken off from the cooking stove.
