関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiant heat temperature sensor which is a detecting means for detecting a radiant heat temperature from a wall surface or a floor surface for use in an air conditioner and for controlling air conditioning.

向の箇所の温度しか捕らえることができない。2. Description of the Related Art In an air conditioner, a radiant heat temperature sensor is attached to, for example, a lower part of a front surface of an indoor unit to catch heat radiated from an indoor wall or floor to indirectly detect the temperature of the wall or floor. , There is one that adds the detected temperature to the air conditioning control. However, the conventional radiant heat temperature sensor can only capture the temperature at a limited location in one direction.

て、左右もしくは上下の視野を独立させている。On the other hand, there is a radiant heat temperature sensor disclosed in Japanese Patent Application Laid-Open No. 63-231134, which detects the temperature of a wide range. As a heat collecting means for collecting radiant heat in a predetermined range, the sensor portion is formed in a convex shape, and the left and right or upper and lower visual fields are made independent.

る。However, in the above-mentioned one, since the plurality of sensors are arranged in independent spaces, there is a problem in that the effect of heat from the outside is not uniform. Since the sensor portion is formed in a convex shape, there is exposure from the mounting surface, which causes a difference in the influence of the left and right air flows.

感度が悪い。そのため、非常に高価なレンズを使用する
か、もしくは非常に感度の高いセンサを用いる必要がで
て、コストに悪影響がある。Further, in the case where the reflecting cylinder is formed in front of the infrared ray transmitting film, there is a problem that the reflecting cylinder increases the size of the device. When a convex lens or the like is used as the heat collecting means, the lens itself absorbs infrared rays, and the heat collecting power is small, resulting in poor sensitivity. Therefore, it is necessary to use a very expensive lens or a sensor having a very high sensitivity, which adversely affects the cost.

検出する輻射熱温度センサを提供することにある。The present invention has been made in consideration of the above circumstances, and an object of the present invention is to make it less likely to be affected by the heat from the outside and to prevent the influence of the external air flow, thereby improving the directional sensitivity. It is intended to provide a radiant heat temperature sensor that holds the radiant heat energy with high accuracy.

る。[Means for Solving the Problems] A pair of reflecting mirrors are arranged in parallel so as to collect the radiant heat energy from the wall surface / floor surface from the directions adjacent to each other, and the reflecting mirrors reflect the focal points of the reflecting mirrors. A temperature sensor that receives the emitted radiant heat energy and detects the temperature is provided.The temperature sensor and the front surface of the reflecting mirror are covered with an infrared ray transmitting film to transmit infrared rays, and each temperature sensor is kept in the same space. It is a radiant heat temperature sensor characterized in that the heat influence from the outside world on the temperature sensor is made uniform and the influence of an external air flow is prevented.

精度に差が生じない。Since the pair of reflecting mirrors are covered with the infrared transmitting film, the radiant heat energy is collected from the directions adjacent to each other in the same space. Since the temperature sensors at the focal positions of these reflecting mirrors are also in the same air layer, even if there is a thermal influence and an air flow influence from the outside, they are blocked and there is no difference in detection accuracy.

【００１０】図中１は、矩形状にした前面側に開口部１
ａを有するケーシングであり、このケーシング１内に
は、図において左右に並んで一体に連設される、一対の
反射鏡２ａ，２ｂが収容される。In the figure, reference numeral 1 denotes a rectangular opening 1 on the front side.
In the casing 1, a pair of reflecting mirrors 2a and 2b, which are arranged side by side in the left-right direction and are integrally connected, are housed.

ている。The peripheral ends of the reflecting mirrors 2a and 2b are fixed by a pressing plate 10, and a heat insulating material 3 made of, for example, styrofoam material is filled between the back surface side and the inside of the casing 1, so that the back surface side is covered. It is designed so that it is not affected by heat.

右方向に異なる指向性が持たされる。Each of the reflecting mirrors 2a and 2b is, for example, a parabolic mirror having the same curvature, and is obtained by subjecting a metal thin plate press-molded product or a resin molded product to surface plating. The axes 4a and 4b are different from each other in the left-right direction so that they intersect at a point of the central axis 5 that is inclined inwardly at the same angle with respect to the center position and extends from the connecting position of the reflecting mirrors 2a and 2b. It has directivity.

ード線によって取り出す構成としている。The heat receiving plates 6a and 6b have a long and narrow bridge fixing body 7 in order to suppress heat conduction from the outside.
It is supported at a predetermined position by a and 7b. Temperature sensors 8a and 8b for detecting radiant heat are bonded and fixed to the rear surface side of the reflecting mirrors 2a and 2b facing the mirror surface using a heat conductive adhesive. The signal outputs of these temperature sensors 8a and 8b are taken out by lead wires (not shown) connected to the temperature sensors 8a and 8b.

輻射も低減されることとなる。Since the temperature sensors 8a and 8b are attached to the heat receiving plates 6a and 6b supported by the elongated bridge fixing bodies 7a and 7b, the temperature sensors 8a and 8b are floated in the air together with the heat receiving plates 6a and 6b, and are caused by heat conduction. The impact is minimal. Further, since the back surfaces of the heat receiving plates 6a and 6b have high reflectance, secondary radiation from the back surfaces to the temperature sensors 8a and 8b is also reduced.
