Kitchen automatic fire extinguishing device achieving zone control

Abstract

The invention belongs to fire extinguishing equipment, and particularly relates to a kitchen automatic fire extinguishing device achieving zone control. The kitchen automatic fire extinguishing device comprises a plurality of fire extinguishing mechanisms, a fire extinguishing box and a control box. A plurality of fire signal transmission devices are further included. The number of the fire signal transmission devices is the same as that of the fire extinguishing mechanisms. The input ends of the fire signal transmission devices are connected with the fire extinguishing mechanisms, and the output ends of the fire signal transmission devices are connected with the control box. According to the kitchen automatic fire extinguishing device, under the conditions that the area of a kitchen is too large, or the kitchen is divided into a plurality of zones, and even kitchens are distributed in different rooms, one corresponding fire signal transmission device only needs to be mounted on each fire extinguishing mechanism, multiple units of equipment can be jointly connected to the control box and the fire extinguishing box, multiple sets of equipment do not need to be mounted, and mounting cost is reduced; and zone control can be carried out on the different zones, targeted fire extinguishing can be carried out when a fire happens, and fire extinguishing materials and kitchen food material losses are greatly reduced.

Description

technical field [0001] The invention belongs to fire extinguishing equipment, and in particular relates to a kitchen automatic fire extinguishing device with zone control. Background technique [0002] At present, there are canteens in public buildings such as hotels, guesthouses, troops, hospitals, schools, enterprises and institutions, and gas stoves are usually installed on the canteen stoves. If the gas stove is out of control, it will cause the cooking oil in the pot It ignites quickly in a very short period of time, and when the fire expands, it will further cause the grease in the fume hood and exhaust pipe to ignite, resulting in a sky-high fire that is difficult to put out. And smoke exhaust pipes have become the key protection objects in the canteen. [0003] The fire extinguishing device currently used in the field of domestic and foreign kitchen fire extinguishing devices is a mechanical drive, using a wire rope to pull the fuse on the temperature sensor through...

AI Technical Summary

Problems solved by technology

[0004] 1. The pulleys used in the installation process cannot turn too much, the distance cannot be too large, and it cannot be installed across spaces and regions. For a kitchen with a large area or a kitchen divided into multiple different areas, multiple sets of equipment need to be installed, and the cost is too high;

[0005] 2. When a fire occurs, the fire extinguishing equipment as a whole starts to extinguish the fire. For a fire in a small area, all the nozzles will be turned on to extinguish the fire. The fire extinguishing is not targeted and accurate, resulting in waste of fire extinguishing materials, and for areas where there is no fire It also caused a large amount of food loss;

[0006] 3. The tensile force of the mechanical driver is large, and the fuse is easily broken due to too much force. Once the fuse breaks due to external force, it will send a fire signal to the equipment, resulting in early spraying and wrong spraying, and the signal transmission speed of the mechanical drive is slow.
