Title:
HEAT SENSOR AND HEAT/SMOKE COMBINATION-TYPE FIRE DETECTOR
Document Type and Number:
WIPO Patent Application WO/2020/250659
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a heat detector which avoids excessively decreasing the heat of a gas moving towards a heat detection unit. This heat detector 1 is provided with a base 1b and a heat detector main body 1a. The base 1b is attached to an attachment surface X11 of a building. The heat detector main body 1a has the shape of a bottomed cylinder and is attached to the base 1b. The heat detector main body 1a is provided with an opening 7, a substrate 2, a heat detection unit 3 and at least one wall 522. The wall 522 controls flow of the aforementioned gas such that the gas passing through the opening 7 flows towards the heat detection unit 3. The wall 522 divides the flow of the gas into multiple gas streams after entering the opening 7 from an outer space SP2. Further, the wall 522 causes the divided gas stream on the side nearer the inner surface of the heat detector main body 1a to travel towards the heat detection unit 3.
