が用いられている。 This type of infrared radiation device has an infrared radiation element 1 disposed on the inner surface of a reflector 6 as shown in FIG. A heating element 9 is embedded in an outer envelope 7 made of a metal pipe having a circular cross section through an insulating layer 8, and a ceramic material such as Fe 2 O 3 , Fe 2 O 3 , etc.
The emissive layer 10 is formed by plasma spraying an oxide such as NiO, MnO 2 , ZrO 2 , Al 2 O 3 or the like. Further, as the reflector 6, a curved one is used.

射ができないという問題があつた。 In such an infrared radiation device, there are two types of infrared rays emitted from the infrared radiating element 1: infrared rays that are reflected by the reflector 6 and irradiated onto the heated object, and infrared rays that are directly irradiated onto the heated object. However, in the case of an infrared radiation device using the infrared radiation element 1 having the above-mentioned shape and structure, the infrared radiation irradiated directly from the infrared radiation element 1 is strong on the surface of the heated object that is the shortest distance from the infrared radiation element 1. There was a problem that it was not possible to irradiate with uniform heating.

としては適さないという問題もあつた。 In addition, long-wavelength infrared rays of 4 to 50 microns are most suitable for drying and baking paint, keeping food warm, heating, etc. as they are effectively absorbed by the heated object, but in order to emit infrared rays of 4 to 50 microns, an infrared radiation element 1 is required. The surface temperature of approximately
It is necessary to set the temperature below 500℃. However, in order to set the surface temperature to 500° C. or less in the infrared radiation element 1 having the above shape and structure, the outer diameter of the outer envelope 7 must be increased to increase the surface area.
As a result, the thickness of the insulating layer 8 interposed between the heating element 9 and the metal envelope 7 increases, the heat capacity increases, and the temperature rise rate of the infrared radiation element 1 at the initial stage of energization becomes slower, especially when used intermittently. Another problem was that it was not suitable as an infrared radiating device.

決をはかつたものである。 The present invention attempts to solve the above problems by improving the shape of the infrared radiating element and its arrangement on the reflector.
以下図に従つて本考案の実施例について説明す

Insulating layers 3 and 4 are formed of magnesia bound with a binder of mica, asbestos, or aluminum phosphate on both surfaces of the heating element 2, which is formed by etching a foil such as Cr into a certain pattern. The emissive layer 5 is formed by applying a mixture of and a heat-resistant paint or a water glass binder.

放射面がほぼ垂直となるよう配設されている。 As shown in FIG. 2, this good infrared radiating element 1 has a plurality of bent surfaces, for example, separated from the reflecting surface of the reflector 6 having a cross-section shape by a certain distance, and approximately in the longitudinal direction of the illumination aperture surface a. It is located on the center b, and is arranged so that its wide radiation surface is substantially perpendicular to the radiation aperture surface 9.

された赤外線は直接被加熱物へ照射されることな

射されるため、被加熱物に対して均一な赤外線照
射が可能となる。 As described above, the present invention uses a thin elongated plate-like infrared radiating element 1, and furthermore, the infrared ray radiating element 1 is radiated with a wide width toward the irradiation aperture surface of the reflector 6. Since the planes are arranged almost vertically, in this radiating device, the infrared rays emitted from the radiation layer 5 of the infrared radiating element 1 are not directly irradiated onto the object to be heated, and most of the infrared rays are emitted by the reflector 6. Since the infrared rays are reflected and irradiated onto the heated object, it becomes possible to uniformly irradiate the heated object with infrared rays.

しても適する。 Furthermore, since the infrared radiation element 1 of the present invention is in the form of a thin long plate, in order to increase the surface area in order to keep the surface temperature below 500°C, the wide side of the infrared radiation element 1 must be further enlarged. In this way, the insulating layer 4 will not become thick, and the rate of temperature rise at the initial stage of energization will not be slowed down, making it suitable as an infrared radiating device for intermittent use.
以上述べたように本考案赤外線放射装置によれ

An infrared ray emitting device of extremely great industrial value can be obtained because it is easy to manufacture and can be manufactured in a simple shape.
