Problems solved by technology

[0006] However, in the alarm of Patent Document 1, in order to allow the detection part to be arranged inside the frame, compared with the design in which the detection part is exposed from the frame, since it has the characteristic of reducing the inflow of smoke into the detection part, it is relevant to let the smoke flow into the detection part. There is still room for improvement in the characteristics of the flow into the alarm body or the detection part
[0007] In addition, in the alarm device of Patent Document 1, since the detection part is arranged at a position opposite to the opening, the detection part directly allows interference such as dust, water vapor or ambient light to enter through the opening. , with this intrusion, it is possible to generate false detections of smoke
[0008] In addition, because the overall shape of the alarm containing the vertical grid and the horizontal grid becomes more complicated, when the mold is used to manufacture the alarm, it will be used to form the shape of the alarm (especially if the vertical grid and the horizontal grid are provided). Around the opening of the gate) the demoulding step becomes more complicated, which may also increase the manufacturing cost

Embodiment Construction

[0200] Hereinafter, an alarm device according to an embodiment of the present invention will be described in detail based on the drawings. In addition, the present invention is not limited by this embodiment.

[0201] [Basic Concept of Embodiment]

[0202] First, the basic concept of the embodiment will be described. The embodiment is roughly an alarm device installed on an installation surface of an installation object, and relates to an installation surface facing the installation surface. Here, the so-called "alarm device" is a device for alarming. Specifically, the device is used for alarming about the detected substance of the gas contained in the monitoring area, such as gas alarms and fire alarms ( smoke alarms) etc. The so-called "surveillance area" is an area to be monitored, specifically, an area where an alarm device is installed, for example, an area within a house (for example, a room, etc.), an area in a building other than a house, etc. In addition, "an obje...
