Abstract

PURPOSE:To make it possible to extend the range of radiation and provide a sufficient degree of heating, by installing a reflecting plate comprising a first parabolic locus cross section and a second parabolic locus cross section, which are focused on a heating element. CONSTITUTION:The radiation heat from a heating element 1 reflected on a first parabolic locus cross section 2 advances directly in the same direction as indicated by A. The radiation heat from the heating element 1 radiated on a second parabolic locus cross section 3 advances directly in the same direction with an inclination of an angle theta to the radiation heat A as indicated by A. Therefore, all the radiation heat discharged from the heating element 1 and reflected on a reflecting plate 4 advances directly in either A or B direction without irregular reflection. It is, therefore, possible to extend the range of radiation, providing a satisfactory extent of heating.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a reflector for an electric stove.

BACKGROUND OF THE INVENTION Conventional electric stoves of this type include, for example,
It had a structure as shown in Publication No. 6110.

That is, as shown in FIGS. 3 and 4, a heater 9 is placed in front of the center of a reflector plate 8 which has a small curved reflective surface 7 in the center and a large curved reflective surface 6 on the outside. The radiation range is expanded by the reflected radiation C by the small curved reflecting surface 7 and the reflected radiation by the small curved reflecting surface 7, and this radiation range can be changed by moving the heater 9 back and forth.

Problems to be Solved by the Invention However, with such a structure, when the reflected radiation C from the large curved reflecting surface 6 is emitted uniformly in the horizontal direction with straightness, the reflected radiation C from the small curved reflecting surface 7 O is diffusely reflected, and when the reflected radiation O of the small curved reflective surface 7 is emitted uniformly in the horizontal direction with straightness, the reflected radiation C of the large curved reflective surface 6 is diffusely reflected. The structure is not such that the reflected radiation C and the reflected radiation O from the small curved reflecting surface 7 emit linear radiant heat at the same time, and although the radiation range is widened, there is a problem in that sufficient warmth cannot be obtained.

Therefore, the present invention provides an electric stove with a reflector that can widen the radiation range while providing sufficient warmth.

Means for solving the problems and the technical means of the present invention for solving the above-mentioned problems consist of a heating element and a reflecting plate provided in the stove body, and the reflecting plate has two parabolas with the heating element as a focal point. The cross-sectional shape is shared and the axes intersect.

For production The effect of this technical means is as follows.

That is, the radiant heat emitted from the heating element and reflected by the reflecting plate travels straight in parallel to the axes of each of the two parabolas, resulting in no diffused reflection. As a result, the radiant heat that travels in a straight line spreads in two directions, making it possible to expand the radiant range while providing sufficient warmth.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 1, 1 is a heating element, 2 is a first parabolic locus cross section with the heating element 1 as a focal point, and 3 is a first parabolic locus cross section 2 that is in contact with the first parabolic locus cross section 2 and has the heating element 1 as a focal point. On the other hand, it is a second parabolic locus cross section with an angle θ centered on the heating element 1.

As shown in FIG. 2, a reflector plate 4 consisting of a first parabolic locus cross section 2 and a second parabolic locus cross section 3 is installed on the stove body 5. As shown in FIG.

Next, the operation of this embodiment will be explained.

The radiant heat from the heating element 1 reflected at the first parabolic locus cross section 2 travels straight in the same direction as shown in A (.

Further, the radiant heat from the heating element 1 reflected at the second parabolic locus cross section 3 has an inclination of an angle θ to the radiant heat A and travels straight in the same direction as the sun. Therefore, all the radiant heat emitted from the heating element 1 and reflected by the reflector 4 travels straight in the direction A or the sun, becoming radiant heat without diffused reflection, and the radiant range can be expanded while providing sufficient warmth. Additionally, this type of stove is often used to heat the feet, and by tilting the angle 0 toward the top of the stove body, it is possible to warm not only the feet but also the waist.

Effects of the Invention As is clear from the description of the above embodiments, the present invention provides sufficient warmth by providing a reflector consisting of a first parabolic locus cross section and a second parabolic locus cross section focusing on the heating element. It is possible to expand the radiation range while providing
