ELECTRIC STOVE

摘要

An electric stove in which heat ray reflection efficiency at a mirror surface portion is increased to reduce loss in heat efficiency. The electric stove (10) has, for example, a sheath heater (26) as an electric heating element placed away from a position directly under an object (120) to be cooked, and also has an upper mirror (12) as a mirror surface portion placed so as to surround the sheath heater (26) and reflecting heat rays radiated from the heater (26). The upper mirror (12) forms a partly elliptic mirror surface. A lower mirror (14) is placed below the sheath heater (26). The lower mirror (14) reflects heat rays, reflected by the upper mirror (12), substantially directly upward to collect heat on the underside of the object (120) to be cooked. The lower mirror (14) forms, for example, a conical mirror surface portion as a rotational conicoid mirror surface portion.
