Description

Kitchen fire-away alarm device

Technical Field

The utility model relates to a kitchen of smoke ventilator sharing is fired from people alarm system's start-up field, especially relates to a kitchen is fired from people alarm device.

Background

The kitchen fire people-leaving alarm system adopts a human body existence detection sensing technology, and can accurately sense the activity range and the activity time of a chef in a kitchen fire area. When the fire people-leaving alarm system is started, the microwave detector starts to detect whether people exist in the kitchen area or not. If no person is detected within a period of time (for example 90 seconds), the fire-leaving person early-warning device is started in a linkage mode, and an acoustic and optical alarm is sent out to warn a cook to return to an operation area in time. If the cook does not timely return to the operation area, after a period of time (for example, 90 seconds), a reminding signal is sent to the control room to remind an operator on duty to timely check the kitchen, and meanwhile, the energy of kitchen equipment is automatically cut off.

The kitchen fire-away alarm system is automatically started, protects in real time, can prevent kitchen fires caused by dry burning, electric appliance faults and the like, and can effectively protect kitchen safety. When a cook opens the range hood, the default cook starts to fire, and the range hood linkage signal can automatically start the fire to leave the human alarm system, so that the kitchen is protected in real time. When the cook finishes firing and closes the range hood, the fire-away alarm system is still electrified, but the microwave detector stops working, and the sound and light alarm is not started any more after the kitchen leaves a person. However, the existing kitchen oil fume extraction fans are not dispersedly and independently arranged in respective kitchens, but a plurality of kitchen rooms share one set of oil fume extraction fan, the service time of each kitchen room is inconsistent, and the oil fume extraction fans cannot be started to ignite and leave people by acquiring the starting signals of the oil fume extraction fans.

Therefore, a device with simple structure, convenient installation and high cost performance is needed to be designed for feeding back whether the kitchen is on fire or not and starting the kitchen fire people-leaving alarm system.
