Kitchen cooking apparatus capable of self-extinguishing

Abstract

The invention discloses a kitchen cooking apparatus capable of self-extinguishing. When a set temperature is reached, a temperature-sensitive valve actuator (6) mounted on a cooking apparatus backboard (3) or a cooking apparatus substrate (1) begins to work, which leads to opening of an automatic temperature-sensitive valve (5); a fire extinguishing medium enters into a system pipe network (10) through a medium inlet (9); a nozzle protective device (8) automatically falls off, spray nozzles (7) begin to spray water mist, and water mist spayed by a plurality of the spray nozzles (7) from different angles forms a sector shape above a burning mouth table (2) so as to cover the burning mouth table (2), thereby achieving the effects of cooling flames, moistening / cooling fuels, removing oxygen and fuel steam used for combustion and reducing radiant heat; when the temperature drops to a set safe range, the automatic temperature-sensitive valve (5) automatically closes; and the above-mentioned operations are repeatedly carried out.

Description

technical field [0001] A kitchen cooking equipment with an automatic fire extinguishing function, belonging to the field of kitchen equipment manufacturing technical background [0002] In recent years, with the rapid development of the national economy, the substantial improvement of people's living standards, the growing prosperity of the catering industry, and the widespread use of modern cooking equipment with high energy input, fires caused by kitchen equipment have occurred from time to time, potentially threatening life and property. The risks keep growing. Compared with other types of fires, fires on kitchen equipment have their own characteristics and are not easy to extinguish, and the fire spreads quickly and has a large heat capacity. In addition to quickly extinguishing the flames on the surface to prevent spreading, it must be cooled to a lower temperature prevent its re-ignition. Nowadays, automatic fire extinguishing and cooking equipment are separated, and...

AI Technical Summary

Problems solved by technology

Nowadays, automatic fire extinguishing and cooking equipment are separated, and the two are not integrated. Experiments have found that foam, dry powder and special fire extinguishing agents can effectively extinguish the flames, but it is difficult to reduce the temperature to a safe range. , can not effectively prevent its re-ignition, and the installation process is complicated, the reagents need to be replaced by professional personnel on a regular basis, and after each use, professional personnel must add reagents to pressurize and debug, the price is expensive, and the work is affected by the restrictions of others , and cannot prevent harmful gases from spreading to the surroundings. After the flame is extinguished and the temperature drops to the normal range, it cannot be stopped automatically. , installation and maintenance are complex and costly
