Problems solved by technology

[0006] In addition, in such an electric heating furnace, when the diameter of the sleeve heater is large, etc., the heat ray radiated by the electric heating element stagnates inside the mirror portion due to the size of the electric heating element, so the second partial elliptical cylindrical portion cannot The heat rays not irradiated to the object to be heated are reflected, so that the first partial elliptic cylindrical portion of the opposing mirror portion may not be efficiently irradiated.
In this case, heat rays cannot be well controlled, and the efficiency of reflecting heat rays from one mirror portion to the opposite mirror portion is also poor.
In other words, the second partial elliptical cylindrical surface cannot fully function as an efficiency improvement, resulting in heat loss, and it is still difficult to sufficiently improve thermal efficiency.
[0007] Furthermore, when cooking fish, meat, and other food materials with such an electri

Abstract

An electric stove in which a degree of design freedom can be increased and thermal efficiency can be further enhanced. A electric stove comprises electric heating elements disposed at positions away from positions directly under an object to be heated, partially elliptical mirror surface parts for reflecting heat rays radiated from the electric heating elements, and first reflective mirror surface parts disposed under the electric heating elements and collecting heat reflected by the partial elliptical mirror surface parts to the underside of the object to be heated. The partially elliptical mirror surface parts each have one focal point in the vicinity of the electric heating element. The partially elliptical mirror surface part and the first reflective mirror surface part are connected such that the major axis line connecting the one focal point and the other focal point of the partially elliptical mirror surface part intersects the first reflective mirror surface part at a desired angle Y.

Description

technical field [0001] The present invention relates to an electric furnace, in particular to an electric furnace for heating a heated body through radiant heat, such as for cooking fish, meat and other foodstuffs. Background technique [0002] The prior art used as the background of the present invention discloses an electric heating stove that suppresses the generation of smoke as much as possible and is downsized so that it can be easily used for cooking even in ordinary households. This electric furnace includes, for example, two support plates, and two mirror portions are arranged facing each other with a predetermined interval between the two support plates. The two mirror portions are respectively formed by the first partial elliptic cylinder portion and the second partial ellipse cylinder portion. Electric heating elements such as a sheathed heater are arranged at positions deviated from directly below the heated body inside the two mirror portions. One side focus ...
