う欠点があつた。Structure of conventional example and its problems As shown in Fig. 1, infrared radiant heaters that have been used conventionally have a housing 1 that stands almost vertically.
There is one in which an electric heater 2 is built into the lower part of the housing, and the inside of the housing 1 is filled with nonflammable oil 3. Another conventional example is one in which a planar heater 4 is arranged on the inner surface of the housing 1, as shown in FIG. Furthermore, instead of the planar heater 4, there is also one in which string heaters are distributed in a distributed manner. These conventional infrared radiant heaters pass electricity through the electric heater 2 and non-flammable oil 3.
Alternatively, the sheet heater 4 is energized to maintain the surface temperature of the housing 1 at 70 to 90°C, and the heated surface of the housing 1 is used as a heat source to radiate infrared rays. in this case,
Since the box 1 is a plane, the view factor decreases as the angle from the normal to the plane of the box 1 increases, and becomes 0 at an angle of 90°. In other words, although the front side of the housing 1 is warm, the area near the side surfaces is not warm.

ように構成したものである。Composition of the Invention In order to achieve this object, a heat source body erected in a nearly vertical direction, an infrared radiating material layer formed on one surface of the heat source body, and a surface vicinity of the infrared radiating material layer are provided. perpendicular to the heat source, and
A plurality of thin plate-like protrusions installed in the vertical direction,
It consists of a heat insulating layer installed on one surface of the heat source, and the heat source is configured so that it can be freely bent in the horizontal direction.

対して均一に輻射エネルギーを分散させることが
できる。 With this configuration, when the heat source is in a nearly flat state, the distribution of radiant energy radiated to the front surface becomes extremely narrow due to the thin plate-like protrusions, resulting in less directivity compared to a completely diffusing surface. tends to increase. Therefore, when the heat source body is bent in a convex shape in the horizontal direction, the normal direction at each position of the heat source body is different, so radiant energy cannot be uniformly distributed in all directions. Can be done.
このように、本発明によれば、輻射したい方向

の矢印は法線方向を示している。 In FIGS. 3, 4, 5, and 6, a heat source A having a planar heater 6 disposed on one surface of a substrate 5 is erected almost vertically. On the other surface of this substrate 5, an infrared radiating material layer 7 of 10 to 200 μm is coated or adhered. Near the surface of this infrared radiating material layer 7, the height L H in the vertical direction is 5 to 5.
Thin plate-like protrusions 8 of 30 mm and 0.05 to 1.0 mm in thickness are installed at intervals L P of 2.5 to 50 mm. Heat source A
A heat insulating material 9 such as glass wool is placed on the surface of the sheet heater 6 to a thickness of about 15 mm so that it can be bent relatively freely. Note that the arrows in FIGS. 4 and 5 indicate the normal direction.
上記構成において、熱源体Aをほぼ平面にした
場合における薄板状突起物8のない時(実線)と
ある時(破線)の輻射エネルギー分布を第6図に
示す。同図において、薄板状突起物のある場合、
輻射エネルギーの分布は非常に狭いものとなり、
熱源体の法線方向に、密度が大となり、法線方向
からの角度が大きくなるにしたがつて極端に輻射

あらわれる。ここで、この熱源体Aを凸状に曲げ
られるようにしたために、それぞれの位置におけ

ことが可能となる。 In the above configuration, when the heat source A is made substantially flat, the radiant energy distribution is shown in FIG. 6 when there is no thin plate-like protrusion 8 (solid line) and when it is present (broken line). In the same figure, if there is a thin plate-like protrusion,
The distribution of radiant energy becomes very narrow,
The density increases in the normal direction of the heat source, and as the angle from the normal direction increases, the density of radiant energy decreases extremely. In other words, directionality appears. Here, since this heat source A can be bent into a convex shape, the heat is radiated directionally in the normal direction of the heat source A at each position, so the radiation is uniform in all directions. It becomes possible to release it.
