Abstract: An electric stove includes an electric heating element arranged at a distance from a position right below a target to be heated. A first mirror surface portion is arranged to surround the electric heating element and configured to reflect heat rays radiated from the electric heating elements. A second mirror surface portion is arranged below the electric heating elements and configured to collect the heat rays reflected by the first mirror surface portion to a side below the target by reflecting the heat rays substantially immediately upwardly. The first mirror surface portion includes a plurality of partial elliptical mirror surface portions having one focus near the electric heating elements and the other focus below the electric heating elements, and the second mirror surface portion includes a partial elliptical mirror surface portion a having one focus near the electric heating elements and the other focus below the electric heating elements.

Abstract: It is aimed to provide an electric stove which is further improved to be able to further reduce a loss in terms of thermal efficiency by further increasing the reflection efficiency of heat rays on a mirror surface portion. An electric stove 10 includes electric heating elements 36 arranged at a distance from a position right below targets to be heated W, a first mirror surface portion 12 arranged to surround the electric heating elements 36 and configured to reflect heat rays radiated from the electric heating elements 36, and a second mirror surface portion 14 arranged below the electric heating elements 36 and configured to collect the heat rays reflected by the first minor surface portion 12 to a side below the targets to be heated W by reflecting the heat rays substantially immediately upwardly.

Abstract: An object is to provide an electric stove which can increase the flexibility of design and further improve thermal efficiency. An electric stove 10 includes electric heating elements 32a and 32b disposed out of positions immediately below objects to be heated 62, partially elliptical mirror sections 16a and 16b reflecting heat rays radiated from the electric heating elements 32a and 32b, and first reflective mirror sections 22a and 22b disposed below the electric heating elements 32a and 32b to gather the heat rays reflected by the partially elliptical mirror sections 16a and 16b towards the lower sides of the objects to be heated 62. The partially elliptical mirror sections 16a and 16b have one foci F1a and F1b in the vicinity of the electric heating elements 32a and 32b, respectively.
