Description

  The present invention relates to a seismic notification device for detecting an earthquake having a predetermined seismic intensity or higher and performing a seismic operation such as interruption of an electric circuit.

There is a seismic relay that detects the occurrence of an earthquake of a certain seismic intensity or higher and outputs a signal to interrupt the electric circuit. The seismic relay used to cut off the electric circuit is usually installed in or near the distribution board in order to cut off the electric circuit by operating the leakage breaker in the distribution board (for example, Patent Document 1).
Since the seismic relay is installed in or near the distribution board in this way, when setting the seismic intensity, it is difficult to operate because it is an operation in or near the distribution board. Therefore, there is a system in which an operation unit is made independent and can be operated in a living room or the like. For example, in Patent Document 2, while a control unit that wirelessly communicates with the seismic relay is installed, a notification unit is installed in a place that is easy to operate, such as a living room, and communication is performed between the control unit and the notification unit. The seismic intensity of relays can be set.

  The seismic notification device 10 configured as described above senses that an earthquake with a seismic intensity equal to or greater than the set seismic intensity has occurred, and starts a seismic operation under the control of the control unit 15. Specifically, the LED 14a emits light upon receiving an earthquake detection and the buzzer 14b sounds. With this operation, the occupant is notified that the seismic operation has started, that is, that a shut-off signal is output after a predetermined time.

Furthermore, immediately before a power failure operation such as 30 seconds before outputting the shut-off signal, the light emission of the LED 14a changes to blinking, and the sound of the buzzer 14b also changes.
Through such an operation, when the set delay time elapses, a shut-off signal is output, the main breaker of the distribution board 4 is shut off, the electrical circuit is shut off, and a power failure occurs. However, if the reset button 24 is operated before the delay time has elapsed since the start of the seismic operation, the seismic operation is stopped and no shut-off signal is output.

FIG. 6 is a vertical cross-sectional view of the seismic notification device 10, showing a cross section taken along line AA of FIG. 2. A state in which the housing 1 is accommodated in the switch box 5 is shown. FIG. 7 is an enlarged view of a portion B in FIG. 6, and is an enlarged view of the periphery of the reset button 24 and the LED 14a.
As shown in FIG. 7, the reset button 24 is disposed in the vicinity of the back surface of the cover plate 3, and presses and bends the area P in front of the reset button 24 of the cover plate 3 made of synthetic resin. Reset operation is possible. Moreover, the exposure window 25 is formed so that the light of LED14a may be irradiated to the area M where the seal | sticker S of the cover plate 3 was affixed.

Thus, since the operation part 12 is covered with the cover plate 3 and is not exposed, it is difficult to operate erroneously, and the appearance can be refreshed, which is preferable. Nevertheless, since the reset button 24 can be operated from the top of the cover plate 3, operability is good.

When an earthquake is detected and an earthquake-sensing operation is started, an LED 14a for notifying the start of the operation is provided. As shown by S1 in FIG. 8, the light passes through the front cover 6a, and the letter “Earthquake Detection Reset” on the seal S is displayed to notify the start of the sensing operation by light emission and reset. The location of the button 24 is notified.
In this case, the operation of the operation unit 12 is performed with the front cover 6a removed, but it is hardly operated except for the initial setting when the seismic notification device 10 is installed. There is no problem even if there is no cover plate 3 that can be opened and closed as shown in FIG.

  Thus, by using the cover plate 3 also as the front cover 6a covering the switch box 5, the number of members can be reduced, and the appearance is also preferable. Since the operation unit 12 cannot be easily operated, it is possible to prevent the child from touching and changing the setting, and the position of the reset button 24 is displayed when the seismic motion is started. It is easy to reset operation as well.
