Abstract

PURPOSE:To sustain the feel of comfortable heating while giving a visual effect of heating by rotating an elongate plate coated with far infrared ray radiating material in front of a red-hot heat generator so as to modulate the radiation wave length and radiation intensity of heat rays which are steadily radiated from the red-hot radiator. CONSTITUTION:A red-hot heat generator 1 is located at the focal point of a reflector 3 which is attached to the unit body 2 and has a parabolic section configuration, and consists of an elongated vertical quartz-sheathed heater. A protective guard 6 is disposed in front of the red-hot heat generator 1. A plurality of elongate plates 5 are vertically disposed across the width behind the protective guard 6 but in front of the red-hot heat generator 1. The elongate plates 5 are rotatably attached to the unit casing 2 through pivot shafts 7 projecting from the top and bottom, and can rotate 90 deg. about the pivot shafts 7 by means of a drive motor 8 and an actuating rod 9. The surfaces of the elongate plates 9 are coated with far infrared ray radiating material 4. Part of heat rays radiated from the red hot heat generator 1 is interrupted by the rotating elongate plates 5, and parts of those which were absorbed by the elongate plates 5 go through the wave length conversion for secondary radiation, quickly changing the radiation wave length and radiation intensity of the heat rays.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a heater that provides a variable radiation wavelength and radiation intensity for a user.

BACKGROUND OF THE INVENTION As shown in FIG. 5, a conventional heater has a red-hot heating element 102 attached to the focal point of a reflecting plate 1o1 having a parabolic cross section.
The configuration was such that heat was radiated to the human body 103 with a constant ratio of radiation wavelength and constant radiation intensity radiated to the front surface.

Problems to be Solved by the Invention In such a conventional configuration, the heat rays emitted from the red-hot heating element 102 are constant, and if the same amount of heat rays is irradiated for a long time, the thermal sensation of the human body 103 will be numbed or The problem was that it was either too hot and didn't feel like a comfortable heating experience.

The present invention solves these problems, and aims to provide a heater that changes the heat rays radiated from a red-hot heating element on the heat receiving side.

Means for Solving the Problems In order to solve the problems, the heater of the present invention includes a reflector and a red-hot heating element, and a long plate coated with a plurality of far-infrared radiating materials in front of the red-hot heating element. and the long plate is rotated by a drive motor.

Effect With this configuration, a part of the heat rays emitted from the red-hot heating element is blocked by the rotating long plate, and the heat rays absorbed by some of the long plates are wavelength-converted and emitted as secondary radiation. Both wavelength and radiation intensity can be quickly changed.

EXAMPLE Hereinafter, one embodiment of the present invention will be explained with reference to FIGS. 1 to 4. In the figure, a red-hot heating element 1 is installed at the focal point of a reflecting plate 3 having a parabolic cross section attached to a main body 2, and is constituted by, for example, a vertically elongated quartz tube type heater. Further, a protective guard 6 is provided in front of the red-hot heating element 1. Inside the protective guard 6 and in front of the incandescent heating element 1, a plurality of vertically elongated plates 6 are arranged horizontally, and are rotatably connected to the main body 2 via support shafts 7 protruding from the upper and lower ends of the elongated plates 6. It is supported by a shaft and rotates 90 degrees around a support shaft 7 by a drive motor 8 and a drive rod 9. The surface of this long plate 6 is coated with far-infrared radiation material 4.

In the above configuration, when the red-hot heating element 1 is energized, it becomes red-hot in a few seconds, and the surface temperature stabilizes in about one minute. Since it is heated to about 960°C to 1100°C in this stable state, the peak wavelength of the heat rays emitted from the surface of the red-hot heating element 1 is 2 to 2.3μ, which is mainly near infrared rays. This heat ray is radiated directly to the front of the main body 2 or via the reflector 3, and a part of the heat ray hits the long plate 5, but since the long plate 6 is covered with the far-infrared radiating material 4, These near-infrared heat rays are also well absorbed, heat the long plate 6, and are re-radiated from the surface as far-infrared heat rays of 3μ or more. Therefore, a mixture of near-infrared heat rays from the heating element 1 and far-infrared heat rays from the elongated plate 5 is radiated to the front of the main body 2.

On the other hand, the long plate 6 is connected to the support shaft 7 via a drive rod 9 by a drive motor 8.
Since it can be rotated around , the amount of near-infrared heat rays from the heating element 1 changes depending on the rotation angle of the long plate 50, and the ratio of near-infrared heat rays to far-infrared heat rays changes. Furthermore, when the long plate 6 is rotated at a certain rhythm, the ratio of near-infrared heat rays to far-infrared heat rays and the amount of heat rays change rapidly in accordance with the rhythm.

Effects of the Invention As described above, according to the present invention, a long plate coated with far-infrared radiating material is rotated in front of the red-hot heating element, so that a certain amount of heat rays emitted from the red-hot heating element is emitted. By changing the wavelength and radiation intensity, it is possible to achieve the effect of continuously maintaining a comfortable heating sensation for the human body while improving the comfort level of the skin temperature sensation and giving a visual heating sensation similar to that of a bonfire.
