していた。Configuration of conventional example and its problems Conventionally, a vertical electric stove having a quartz tube heater has one vertical quartz tube heater 101 and this quartz tube heater 1, as shown in FIGS. 1 and 2.
A parabolic reflector 102 with a focal point at the center of 01
Therefore, there was a problem in that the capacity of the heater could not be switched with this structure alone.

点を有していた。 Therefore, methods to switch the heater capacity include installing two heaters in parallel with half the current capacity and switching them, an automatic intermittent method in which the heater automatically repeats on and off using a thermal timer,
Alternatively, a phase control method using electronic control, which is used in kotatsus, etc., may be considered. However, when two heaters are installed in parallel by reducing the heater capacity by half, the overall length of the heater becomes short, and the features of the vertical quartz tube heater cannot be fully utilized. In addition, in the automatic on/off method using a thermal timer, the heater repeatedly turns on and off, causing a difference in radiant heat to the person taking the heat, and is not generally a preferred method for switching capacity. Furthermore, although the phase control method using electronic control can be adjusted steplessly, it is expensive and goes against market demands, and there are problems in that an appropriate method cannot be found for switching the heater capacity. was.

合成して反射面を形成したものである。Structure of the invention This invention consists of two quartz tube heaters with different capacities that are arranged vertically in parallel, and a reflector. Disposed in the front-rear direction, the reflecting plate has a reflecting surface formed by combining two parabolas each having a focal point at the center of the two quartz tube heaters.
実施例の説明
以下本考案の実施例を第３図〜第５図に基づい
て説明する。DESCRIPTION OF EMBODIMENTS Examples of the present invention will be described below with reference to FIGS. 3 to 5.

置させて設けている。 In the figure, 1 is the main body case of an electric stove, which is a vertically elongated case with an open front. Inside this main body case 1 are two quartz tube heaters 2 and 3 with different capacities.
The quartz tube heater 2 with a large capacity is placed in the front, and the quartz tube heater 3 with a small capacity is placed in the rear.

（O1F＝Ｐ1/2）を軌跡とする形状を成している。 The reflectors disposed behind the quartz tube heaters 2 and 3 include a parabolic reflector 4 whose focus is at the center of the quartz tube heater 2, and a parabolic reflector 5 whose focus is at the center of the quartz tube heater 3. Two reflectors are combined and
formed by combining. In other words, the shape of the reflector between AB and CD is such that the Y-Y axis and the X-X axis orthogonal thereto are the reference axes, the intersection of these two axes is 0, and the center of the quartz tube heater 2 is E. Then, the parabola with focal length OE is X 2 = 2PY (OE =
P/2) as a locus, and the shape of the reflector between BC is the X 1 -X 1 axis which is higher than the XX axis,
With the Y-Y axis orthogonal to this as the reference axis, the intersection of these two axes is set as "0 1 ", and the center of the quartz tube heater 3 is set as F.
Then, the parabola whose focal length is O 1 F is X 1 2 = 2P 1 Y
It has a shape whose locus is (O 1 F=P1/2).

ツトの効果を成すものである。 In the above configuration, when the quartz tube heater unit 2 is energized by the switching power switch 6, the radiant heat emitted from it is reflected directly or between the reflectors AB and CD, and is irradiated forward in parallel to the Y-Y axis. . In addition, when the quartz tube heater 3 is energized, the radiant heat emitted from it, which has a lower capacity than the quartz tube heater 2, is reflected between the reflectors BC and Y-Y
It irradiates forward parallel to the axis and achieves a low wattage effect when switching capacity.
