Abstract

PURPOSE:To cause radiation heat to be expanded wider in the side direction on the periphery, make area to absorb heat larger, and improve the plane-like glitter for use in the interior of a house, by making the size of a reflecting cell of a member having a large number of holes larger on the periphery and smaller in the central part of said member. CONSTITUTION:At the rear of a high temperature radiation heater 6, a reflecting plate 7 having a parabolic shape in cross section is secured to the main body of a stove 5 through an upper and lower reflecting plate 8. The high temperature radiation heater 6 is also secured to the upper and lower reflecting plate 8 and located approximately at the focus of the parabolic shape of the reflecting plate 7. In front of the high temperature radiation heater 6, a member 9 having a large number of holes is located over whole range of the opening of the reflecting plate 7. The member 9 having a large number of holes is composed of a large number of reflecting cells 10 surrounded with metal foil having a honeycomb shape. Said cells are made of material having high reflectivity (e.g., aluminum) and made up of a foil-like thin plate of about 30mum thickness. The reflecting cells 10 are arranged concentrically in such a manner that the size of said cells is made smaller in the central part and made to become larger radially toward the periphery.

待できるものではないという問題があった。Problems to be Solved by the Invention However, with such a structure, the radiant heat a that should spread laterally as shown in FIG. There was a problem in that there was a large energy loss as the energy traveled along the route, and that sufficient lateral spread could not be expected.

そこで、本発明は、さらに側方への輻射熱を広げ採暖面
積を広くし、面状に輝くインテリア性をそこなわない電
気ストーブに関するものである。Therefore, the present invention relates to an electric stove that further spreads radiant heat to the side, increases the heating area, and does not impair the interior appearance of the heater.

問題点を解決するための手段 そして上記問題点を解決する本発明の技術的な手段は、

央部は小さくしたものである。Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
A high-temperature radiant heater, a reflective plate provided on the back side of the high-temperature radiant heater, and a porous member provided on the front side of the high-temperature radiant heater, the porous member having a large number of honeycomb-shaped reflective cells, The size of the reflection cell is large at the outer periphery and small at the center.

作　　用 この技術的手段による作用は次のようになる。For production The effect of this technical means is as follows.

壁面で反射せずに通過するものが多くなる。That is, the radiant rays and infrared rays generated by the high-temperature radiant heater are reflected by the walls of the reflection cells of the porous member, or are passed through without being reflected, and are radiated forward. The size of the fly-cam-shaped reflection cells of the porous member is large at the outer periphery and small at the center, so the high-temperature radiant heater emits light directly from the wall of the cell, which increases its straightness. More light passes through the cell wall without being reflected.

その結果、輻射熱は中心部では低下することなぐ外周部
では側方へより広がる特性となり、採暖面積を広くし、
面状に輝くインテリア性のある電気ストーブにすること
ができる。As a result, the radiant heat does not decrease in the center, but spreads out to the sides at the outer periphery, increasing the heating area.
It can be made into an electric stove with interior decoration that shines in a planar shape.
