Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rain sensor device capable of catching a rainfall condition such as a daylighting window and automatically opening and closing or issuing an alarm.

(Prior Art) As shown in FIG. 1, a conventional rain sensor (a) has an electrode circuit (c) formed of copper foil on a substrate (b) made of synthetic resin, and the electrode circuit (c) The one that was made to conduct and signal when rain was accumulated between the plus and minus of) was used widely.

(Problems to be solved by the invention) In the case of the above-mentioned conventional example, since one electrode circuit (C) was formed on the substrate (B), the rain sensor (A) was corroded by dust or the like. In this case, there was a problem that each rain sensor (a) had to be removed from the lighting window or the roof and replaced with a new one.

The present invention has been made in view of the above-mentioned points, and it is an object of the present invention to provide a rain sensor that has a plurality of rain sensors and thus can be improved in life and maintenance by providing a plurality of rain sensors.

(Means for Solving the Problem) A rotatable rain sensor plate provided with a substrate provided with a shaft portion substantially at the center of the disk and provided with electrical contacts and a group of independent rain sensors, and a rain sensor plate A rotatable case that allows one to be exposed, and the substrate, the rain sensor plate, and the case are connected to each other via a shaft portion of the substrate.

(Operation) With the above configuration, even if one rain sensor fails, another rain sensor plate is rotated to bring it into contact with the electric contacts of the substrate, and a case is rotated on this rain sensor plate to newly create a new one. Make sure the rain sensor of is exposed on the surface.

(Example) As shown in FIG. 2 and FIG. 3, A is a substrate 3 made of a metal plate or a synthetic resin plate in which a shaft portion 1 is provided at a substantially central portion on a disk and electric contacts 2 are provided. And a rotatable rain sensor plate 5 provided with an independent rain sensor group 4 which is brought into contact with the electrical contacts 2 on the substrate 3 so that one of the rain sensor plates 5 can be exposed. The rotatable case 6 is provided, and the shaft portion 1 of the substrate 3 is provided.
The rain sensor device is configured such that the rain sensor plate 5 is inserted into and the case 6 is also fitted onto the shaft portion 1 of the substrate 3 on the rain sensor plate 5.

Therefore, even if one of the rain sensor groups 4 of the rain sensor plate 5 fails, a new rain sensor can be exposed by rotating the rain sensor plate 5. At this time, the new rain sensor is brought into contact with the electric contact 2 of the substrate 3. The case 6 located at a position corresponding to a new rain sensor on the rain sensor plate 5 is arranged so as to expose the space 7. In addition, 8 may rotate the rain sensor plate 5 with a string or the like.

(Effect of the Invention) As described above, the present invention is composed of a rotatable rain sensor plate provided with a rain sensor group on a substrate provided with a shaft portion and electrical contacts, and one of the rain sensor group of this rain sensor plate. Since a case is arranged so that only the surface of the rain sensor is exposed, even if one rain sensor fails, the rain sensor plate can be rotated so that the new rain sensor can be exposed from the case. Maintenance of the rain sensor can be performed with a simple operation, and the long-term service life can be improved.
