Abstract
A stovetop fire suppression system is provided which senses the stovetop environment, assesses a fire condition, and limits a fuel or electricity heat source upon determination of a stovetop fire condition. Either, or both of, sound or heat may be monitored for the presence of a fire. Sensed day can be processed for spectral density or rate of rise for subsequent comparison to thresholds or predetermined density values. Upon determination of a stovetop fire condition a fire suppression module triggers, for example, a valve or switch to extinguish the stovetop heat source.
Claims6
A stovetop fire suppression system, comprising:
- a fire suppression control device comprising:
- a processor;
- a plurality of sensors comprising:
- at least one microphone and at least one temperature sensor;
- a user interface;
- a memory;
- a fire suppression module;
- and
- a database comprising fire detection data and relational data,
- wherein, the processor determines a fire condition based on comparing at least two sensed conditions on a stovetop to respective relational data;
- and
- a fire suppressor device comprising a fuse and fire suppressing powder, wherein
- the fire suppressor device releases a fire suppressing powder when a flame contacts the fuse and emits an audible blast upon activation of the fire suppressor device;
- and
- wherein, the fire suppression control device sends a signal which activates a valve or a switch turning off energy to the stove based on the processor's determination of a fire condition.
