Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a renovated self-consumption appliance installed in a kitchen or the like.

[Background technology]

Conventionally, heat detectors and fire extinguishing agent nozzles were installed in the kitchen and its exhaust tact to detect an abnormal rise of 64 degrees Celsius. A fire extinguishing casket has been proposed in which two injections of extinguishing agent are made. In the conventional kichikiri 7-sho-dai-omote-n, which uses η1 sword, a mechanical contact system using Simetal or the like is often used as a heat sensor. This type of mechanical contact type sensor has a preset temperature Kt, and detects an abnormal temperature rise when the 1d ambient temperature approaches or exceeds this set temperature. An output meeting is to be generated. therefore.

In the conventional example, the extinguishing agent is injected suddenly, and is the temperature within a dangerous range where the extinguishing agent can be injected? I had a hunch that I couldn't know what was going on. Another small conventional example is that the person cooking in the kitchen knows how much the temperature is currently rising in the kitchen or inside the exhaust tact, how close it is to the set temperature, etc. Unable to do anything, I cut 71
'l'/(i) There was a problem in that no one could tell whether or not ll was working properly.

[Ishikawa's purpose] The present invention has been made in view of the above points,
Is it possible to display an increase in the condensation from moment to moment in a place where large losses are handled, such as a kitchen, and continuous changes in temperature up to the injection of extinguishing agent? If it is possible to keep a constant watchful eye and the temperature is in a dangerous range where fire extinguishing agent is being injected, then it is possible to use SiJ or TII juice. Did you make it happen?小大表1i'j ”chVSuppliedT8
