報に開示されているものがある。(Prior Art) In general, for example, in an air conditioner, an indoor unit installed indoors is equipped with an air temperature detector that detects the indoor air temperature and a radiant temperature detector that detects the radiant rJJ temperature of walls, etc. The indoor temperature 'ar* is adjusted to the set temperature based on these rain detection signals. The radiation rJ4 temperature detector in the air conditioner is a simple type that can be manufactured at low cost, and this simple type radiation temperature 1 detector is disclosed in Japanese Patent Application Laid-Open No. 149751/1983. There are some.

On the other hand, the back of the case is covered with a heat insulating material.

という問題があった。(Problems to be Solved by the Invention) In the radiation tJ4 temperature sensor described above, the temperature sensing element is simply supported in the center of the storage space, and only the surface of the sensing element is exposed to radiant heat, that is, from the wall etc. Since it serves as a heat receiving surface that receives the emitted heat rays, there is a problem that the amount of heat received is small, making it impossible to accurately detect the radiant temperature, making it impossible to perform accurate air conditioning control, etc.

輻Ill潟度を検出できないという問題がある。In addition, although the temperature sensing element is covered with the above-mentioned transparent plate, some transparent plates, such as acrylic plates, transmit only visible light and do not transmit infrared light. Heat rays (radiant heat) with similar properties will not pass through,
There is a problem that the degree of gradient cannot be detected.

いう欠点がある。Further, although a temperature sensing element is provided within the storage space, there is a drawback that natural convection occurs within the storage space, and heat transfer due to this convection increases, so that the temperature sensing element does not detect the true radiant temperature.

があるという問題があった。Furthermore, since the front of the temperature sensing element in the above-mentioned radiant temperature detector is open in a hemispherical manner, it picks up most of the radiant heat coming from the front, making it impossible to detect only the radiant heat from a specific wall, etc. However, there were problems such as poor directivity and limited air conditioning control.

Further, a temperature detection element (2) is provided to detect the temperature of the radiant heat absorption plate (3). In addition, the front surface of the storage chamber (5c) of the insulation case (5) is covered with an air insulation layer (9) having a thickness that does not cause natural convection to the radiant heat absorption plate (3), so that the radiant heat is absorbed.

。Therefore, since the radiant heat is infrared rays, it reliably passes through the radiant heat transmitting film (8) made of polyethylene, polypropylene, etc. and is absorbed by the radiant heat absorbing plate (3). Moreover, since the air insulation layer (9) between the radiant heat permeable membrane (8) and the radiant heat absorbing plate (3) has a thickness that does not cause natural convection, the front surface of the radiant heat absorbing plate (3) is connected to the outside air. The heat conduction of the air alone ensures a reliable heat shield, and at the same time, radiant heat is reliably transferred. Furthermore, since the radiant heat absorption plate (3) receives radiant heat on its front surface and conducts it to the temperature detection element (2), the heat receiving surface becomes wider and the radiant temperature can be detected accurately, making air conditioning control etc. more accurate. can do well.

際の人体等に近い分光輻射特性を得るようにしている。As shown in FIG. 3, the paint layer (4) is a paint having a spectral absorption rate that roughly matches the spectral reflectance of human skin or clothing, or conversely, the spectral absorption rate of human skin or clothing, such as tetrafluoride. Fluororesins such as ethylene resin (PTFE) and titanium oxide (Ti
02) and other pigments. The radiant heat transfer coefficient of the paint WJ (4) is made to approximately match the radiant heat transfer coefficient of the human body, etc., so that the radiant fJJ temperature with respect to the human body can be detected with high accuracy. That is, the spectral reflectance of skin and clothing is high in the visible light and near-infrared light regions, and close to zero in the infrared light region, so the paint layer (4) is made to correspond to this spectral reflectance, for example. We aim to obtain spectral radiation characteristics similar to those of the actual human body, such as skin color or cream color.

They are arranged in a row to form a U-shaped cross section, and the inside is configured as a storage chamber (5c). The radiant heat absorption plate (3) is connected and stretched at the side end of the side wall portion (5b), and the absorption plate (3)

5c), and a front air insulation X1 (9) is formed between the permeable membrane (8) and the paint layer (4). The radiant heat transmitting plate 1 (8) is formed of a thin film made of an infrared Iil transparent resin such as polyethylene or polypropylene, and reliably transmits the radiant heat and supplies it to the radiant heat absorbing plate (3). The plate (3) is isolated from the outside air to prevent heat due to convection such as wind from being transmitted to the absorption plate (3). When the above-mentioned radiant heat transmitting film 8) is formed of polyethylene with a thickness of 30 μm, for example, its spectral transmittance becomes as shown in Fig. 4, and the wave number is 4000C.
Almost 90% of the infrared rays from I-1 to 500C11-1 are transmitted through, and the radiant heat that is heat rays (infrared rays) is reliably transmitted and transmitted to the radiant heat absorption plate (3). Further, the radiant heat transmission 1 m (8) may be formed by a cut-on filter that transmits only infrared rays having a wavelength of 6 to 7 μm or more, and only radiant heat may be transmitted to the radiant heat absorption plate (3).

The distance between the plates is expressed as actual mA. When the distance between the plates becomes larger than this actual LmA, natural convection occurs and heat transfer due to this convection increases. Therefore, if the thickness of the front air insulation layer (9) in this example is increased, the insulation effect will increase, but if it is made thicker than the solid line A, the insulation layer (9) will increase in thickness.
9), natural convection occurs and convective heat transfer occurs in addition to radiant heat, so much of the heat transferred to the absorption plate (3) as 5u+~10111111 is 11g1()1 heat that passed through the permeable membrane (8). It is configured so that

It constitutes a heat collecting means that collects only the radiant heat emitted from the front wall. The reflector tube (10) is formed into a horn shape whose rear end almost coincides with the inner peripheral edge of the side wall portion (5b) of the heat insulating case (5), and which spreads outward from the rear end toward the front. Only the radiant heat in a predetermined range enters the reflector tube (10), and direct radiant heat transmission 'AM!
