Description
【０００１】[0001]
本考案は、鏡面の曇り止め機能を備えたカ−ブミラ−に関する。 TECHNICAL FIELD The present invention relates to a curve mirror having a mirror surface anti-fog function.
【０００２】[0002]
従来、道路の曲り角などに設置するカ−ブミラ−はステンレス板、アクリル板 、ガラス板などを弯曲成形し、鏡板となし、その裏面に支柱を取付ける取付け枠 を取り付けて構成されている。 ところで、カ−ブミラ−は、寒冷地においては、鏡面に曇りが生じ反射能力が 失なわれることがある。この鏡面の曇りは、周囲の温度と鏡板の温度差によって 生じる。すなわち、夜間から早朝、特に明け方の冷え込みに伴って鏡板の表面温 度も低温となり、この鏡板に触れる空気中の水分が結露して付着し鏡面が曇る。 この曇りが生じると鏡面の反射能力が減じ、そこに写る視界が悪くなるので、カ −ブミラ−としての機能が失われ、交通安全上大変危険になる。この危険を解消 するため、鏡板の裏側に蓄熱材を設け、昼間の熱を蓄熱材に蓄め、これを夜間に 鏡面に放熱させることにより、鏡板を外気以上の温度に温め、鏡面に結露が生じ るのを防止することが知られている（実開昭６１−１９８９０１号）。 Conventionally, a curve mirror installed at a corner of a road is formed by bending a stainless plate, an acrylic plate, a glass plate, etc., into a mirror plate, and attaching a mounting frame for mounting a support to the back surface of the mirror plate. By the way, in cold regions, Kabumira may lose its reflection ability due to fog on the mirror surface. The fog on the mirror surface is caused by the temperature difference between the ambient temperature and the mirror plate. In other words, from night to early morning, especially as dawn cools, the surface temperature of the mirror plate also becomes low, and the water in the air touching this mirror plate is condensed and adheres to cloud the mirror surface. When this fog occurs, the reflecting ability of the mirror surface is reduced and the visibility in the area is deteriorated, so that the function as a car mirror is lost, which is very dangerous for traffic safety. In order to eliminate this danger, a heat storage material is installed on the back side of the mirror plate to store heat in the daytime in the heat storage material and dissipate this heat to the mirror surface at night, thereby warming the mirror plate to a temperature higher than the outside air, and dew condensation on the mirror surface. It is known to prevent the occurrence (Saikai 61-198901).
【０００３】 しかし、この鏡板の裏側に蓄熱材を設けたものにおいては、次のような問題点 がある。すなわち、寒冷時には、昼間に蓄熱材に蓄えられた熱が鏡板に伝わり 放熱されるため、鏡板の加温を朝方まで維持し難く、そのため朝方に鏡面に曇り が生じ易い。また、強い寒冷時には、蓄熱容器の蓄熱が底をつき、逆に蓄熱容 器自体が冷却され低温となり冷気を蓄え、この冷気が日の出時に鏡板に伝わるた め、太陽が鏡面に当っても鏡面の温度上昇が遅れ、周囲の気温より低くなり鏡面 に結露が生じやすい。 本考案者は先に上記の問題点を解消するため、鏡板と蓄熱材との間に空間を設 けて蓄熱材から鏡板への放熱が徐々に行えるようにすることを提案した（実願平 ３−６４４４２号）が、この場合上記の問題点は解決したが、上の問題点の 解消には十分とは言い難い。However, the one in which the heat storage material is provided on the back side of the end plate has the following problems. That is, when it is cold, the heat stored in the heat storage material during the day is transmitted to and dissipated to the end plate, so it is difficult to keep the end plate warm until the morning, and therefore the mirror surface tends to become cloudy in the morning. Also, in the case of a strong cold, the heat storage of the heat storage container bottoms out, and on the contrary, the heat storage container itself is cooled to a low temperature and stores cold air, and this cold air is transmitted to the end plate at sunrise, so even if the sun hits the mirror surface The temperature rise will be delayed, and the temperature will be lower than the ambient temperature, and condensation will be likely to occur on the mirror surface. In order to solve the above problems, the present inventor has proposed to provide a space between the end plate and the heat storage material so that heat can be gradually released from the heat storage material to the end plate (actual application: No. 3-64442) solved the above problem in this case, but it cannot be said to be sufficient to solve the above problem.
【０００４】[0004]
本考案は、上記の事情に鑑み、厳しい寒冷地においても、鏡面に曇りを生じな くしたカ−ブミラ−を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a curb mirror in which a mirror surface is not fogged even in a severe cold region.

FIG. 1 is a sectional view showing an example of the curve mirror of the present invention. In FIG. 1, 1 is a reflector plate. The reflector plate is formed by bending a stainless plate, an acrylic plate, a glass plate, or the like. Reference numeral 2 is a back cover, which is made of a steel plate or the like. 3 is a surface heating element. The surface heating element is an aluminum foil electric resistance circuit, carbon, carbon fiber, etc. sandwiched by a copper plate, and a sheet-shaped electric heating element is covered and insulated with a synthetic resin sheet such as polyvinyl chloride, polyethylene or polyester. Things. The surface heating element that emits far infrared rays can be preferably used. Reference numeral 4 is a container in which a heat storage material is enclosed, which is a container made of synthetic resin such as polyethylene or polyvinyl chloride or a metal. Reference numeral 5 is a heat storage material such as an aqueous solution of polyvinyl alcohol, a gelling solution of a super absorbent polymer, or an antifreezing solution such as ethylene glycol, diethylene glycol monoethyl ether, glycerin or isopropanol. A gel or liquid heat storage material is used. Reference numeral 6 is a stopper plate for connecting the reflector plate 1 and the back cover 2. Reference numeral 7 is a cover of the reflecting mirror, and 8 is a solar cell attached to the upper part of the cover. Reference numeral 9 is an electric wire that connects the solar cell and the surface heating element. Reference numeral 10 denotes a support member attached to the back cover 2, and this support member is fixed to the column 11.
【０００７】 本考案のカ−ブミラ−において、昼間に蓄熱容器４内のゲル状又は液状の蓄熱 材５に熱エネルギ−が吸収蓄熱される。この熱エネルギ−が夜間から朝方の気温 低下に伴って放熱される。蓄熱容器４から放出された熱は反射鏡板１を温める。 そのため反射鏡面は外気以上の温度となり、鏡面に結露が生じるのを防止する。 しかして、本考案のカ−ブミラ−においては、反射鏡板１と蓄熱容器４との間 に面発熱体３を設けてある。この面発熱体３は次の作用をなす。すなわち、昼間 に太陽エネルギ−が太陽電池により電気エネルギ−に変えられ、この電気エネル ギ−が面発熱体３で熱エネルギ−に変えられ、この熱エネルギ−が蓄熱容器内に 蓄えられるので、昼間に蓄熱容器により多量の熱エネルギ−を蓄えることができ る。そのため、夜間から朝方の気温低下が厳しくても蓄熱容器内の蓄熱が底をつ いてしまうことが少なくなる。したがって、夜間から朝方の気温低下が相当厳し くても反射鏡面は外気以上の温度に維持でき、鏡面に結露が生じるのを防止する ことができる。In the curve mirror of the present invention, thermal energy is absorbed and stored in the gel or liquid heat storage material 5 in the heat storage container 4 during the daytime. This heat energy is radiated as the temperature drops from night to morning. The heat released from the heat storage container 4 warms the reflector plate 1. Therefore, the temperature of the reflecting mirror surface becomes higher than the temperature of the outside air, and dew condensation on the mirror surface is prevented. In the curve mirror of the present invention, the surface heating element 3 is provided between the reflector plate 1 and the heat storage container 4. The surface heating element 3 has the following function. That is, in the daytime, the solar energy is converted into electric energy by the solar cell, and this electric energy is converted into heat energy by the surface heating element 3, and this heat energy is stored in the heat storage container. A large amount of heat energy can be stored in the heat storage container. Therefore, even if the temperature drop from night to morning is severe, the heat storage in the heat storage container does not reach the bottom. Therefore, even if the temperature drop from night to morning is fairly severe, the reflecting mirror surface can be maintained at a temperature higher than the outside air and dew condensation on the mirror surface can be prevented.
【０００８】 また、夜間から朝方の気温低下が極めて厳しくて蓄熱容器内の蓄熱が底をつい てしまてっも、日の出と共に太陽光線が太陽電池に当り、面発熱体３が発熱し、 この熱が反射鏡板１を加温する。そのため反射鏡面１は外気以上の温度となり、 鏡面に結露が生じるのを防止することができる。この面発熱体が無い場合は、前 述したように、蓄熱容器自体が冷却され低温となり冷気を蓄え、これが反射鏡板 に伝わるため、日の出時に太陽が反射鏡面に当ってもこの鏡面の温度上昇が遅れ 、そのため鏡面に結露が生じやすい。本考案によるとこの従来のカ−ブミラ−の 欠点が解消できる。面発熱体は、その厚さが薄いのでコンパクトに設計でき、ま た加工性がよいので鏡板の曲面に合わせて容易に設置することができる。太陽電 池は太陽光線を受けやすい適宜の位置に設置する。Further, even if the temperature drop from night to morning is extremely severe and the heat storage in the heat storage container bottoms out, the sun rays hit the solar cell at sunrise and the surface heating element 3 generates heat. Heats the reflector plate 1. Therefore, the temperature of the reflecting mirror surface 1 becomes higher than the temperature of the outside air, and it is possible to prevent dew condensation on the mirror surface. Without this surface heating element, as described above, the heat storage container itself is cooled to a low temperature and stores cold air, which is transmitted to the reflecting mirror plate, so that even if the sun hits the reflecting mirror surface at sunrise, the temperature of this mirror surface rises. Delayed, so that dew condensation is likely to occur on the mirror surface. According to the present invention, the drawbacks of the conventional curve mirror can be solved. Since the surface heating element is thin, it can be designed compactly and has good workability, so it can be easily installed according to the curved surface of the end plate. The solar battery will be installed at an appropriate position that is susceptible to sunlight.
【０００９】 上記の例においては、蓄熱容器の裏に直接裏蓋を設けたが、蓄熱容器と裏蓋と の間に発泡ポリスチレン、発泡ポリウレタンの如き断熱材を介在させてもよい。 図２はこの実施例の一例を示した断面図である。図２において符号１２が断熱材 であり、他の符号は図１と同じである。この断熱材１２を介在させることによっ て、蓄熱容器に有効に蓄熱することができ、また蓄熱された熱を有効に反射鏡板 の加温に利用することができる。In the above example, the back cover is provided directly on the back of the heat storage container, but a heat insulating material such as polystyrene foam or polyurethane may be interposed between the heat storage container and the back cover. FIG. 2 is a sectional view showing an example of this embodiment. In FIG. 2, reference numeral 12 is a heat insulating material, and other reference numerals are the same as those in FIG. By interposing the heat insulating material 12, heat can be effectively stored in the heat storage container, and the stored heat can be effectively used for heating the reflector plate.
【００１０】[0010]
以上述べたように、本考案のカ−ブミラ−は、鏡板の裏側に、面発熱体、ゲル 状又は液状蓄熱材を収容した蓄熱容器及び裏蓋を順次設け、且つ面発熱体に太陽 電池を電線で接続したので、昼間に太陽電池により面発熱体が発熱し、この熱が 周囲気温の熱と共に蓄熱容器に蓄熱されるから、より多量の熱が蓄熱材に蓄熱さ れ、そのため夜間から朝方にかけて周囲の気温が相当低下しても、蓄熱容器の熱 が鏡板に伝わり、鏡板を周囲の気温より高く保ち鏡板に結露が生じ、曇るのを防 ぐことができる。 また、夜間から朝方の気温低下が極めて厳しくて蓄熱容器内の蓄熱が底をつい てしまてっも、日の出と共に太陽光線が太陽電池に当り、面発熱体が発熱し、こ の熱が鏡板を加温する。そのため鏡面は外気以上の温度となり、鏡面に結露が生 じるのを防止することができる。 このように、本考案のカ−ブミラ−は厳しい寒冷地においても、鏡面に結露が 生じる曇るのを防止することができるので極めて有用である。 As described above, in the curb mirror of the present invention, a surface heating element, a heat storage container containing a gel or liquid heat storage material and a back cover are sequentially provided on the back side of the end plate, and a solar cell is mounted on the surface heating element. Since they are connected by electric wires, the surface heating element is heated by the solar cell in the daytime, and this heat is stored in the heat storage container together with the heat of the ambient temperature, so a larger amount of heat is stored in the heat storage material, and therefore nighttime to morning. Even if the surrounding air temperature considerably drops over time, the heat of the heat storage container is transferred to the end plate, keeping the end plate higher than the surrounding air temperature to prevent dew condensation on the end plate, which prevents fogging. Also, even if the temperature drop from night to morning is extremely severe and the heat storage in the heat storage container bottoms out, the sun rays hit the solar cells at the sunrise and the surface heating element generates heat, which heats the end plate. Warm. Therefore, the temperature of the mirror surface becomes higher than the temperature of the outside air, and it is possible to prevent dew condensation on the mirror surface. As described above, the curb mirror of the present invention is extremely useful because it can prevent the mirror surface from becoming clouded due to dew condensation even in a severe cold region.
