ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a cooking utensil, and more particularly to an energy-efficient cooker.
2. Description of Related Art
The conventional metal cooker is not energy-efficient in view of the fact that heat is slowly transferred from the bottom of the cooker to the entire body of the cooker, and that the heat transfer does not take place in a uniform pattern, and further that the cooker is not provided with means to prevent the heat loss.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an energy-efficient cooker, which is formed of a main body, a base body, and a lid. The main body has an open top which is covered by the lid. The side wall and the bottom wall of the main body contain a vacuum space extending throughout the side wall and the bottom wall. The vacuum space is partially filled with an action fluid capable of effecting a fast and uniform heat transfer. The base body and the lid have a vacuum space. The main body is then provided with an insulation body circumventing the side wall of the main body. The insulation body contains a vacuum space. In light of the vacuum spaces of the base body, the lid, and the insulation body of the main body, the energy-efficient cooker of the present invention is capable of preventing the loss of heat.
The features and functions of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention in reference to the accompanying drawings.
