Invention embodiment

Detailed ways

In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following will be described in detail in conjunction with embodiments and accompanying drawings.

As shown in Figure 1, the integrated automatic fire extinguishing system for household kitchens includes a fire extinguishing device, a plurality of nozzles 8, a main fire extinguishing line communicating with the plurality of nozzles 8, a gas control valve 10 arranged on the main gas pipeline of the household, and a tap water pipeline 1. The upper water flow linkage control valve 2.

The fire extinguishing device includes a container 3 for storing fire extinguishing agents, a first pipeline connected with the container 3, a mechanical control valve 4 arranged on the first pipeline, and a mechanical control valve 4 arranged between the first pipeline and the container 3. To deliver the fire extinguishing agent in the container 3 to the gas cylinder 6 in the main pipe. In this embodiment, the fire extinguishing agent is a kind of fire extinguishing agent, which can be liquid, gaseous or powdery. It is stored in the container 3 and can chemically react with the burning material, such as fuel oil, and form a covering on the surface of the burning material. Layer to isolate the burning material from the air and play a role in extinguishing the flame.

The water flow linkage control valve 2 is arranged between the tap water pipe 1 and the main fire extinguishing line, and its function is to use tap water to cool the stove after the fire source is extinguished to prevent re-ignition. In this embodiment, the first pipeline and the tap water pipeline 1 are respectively connected to the main pipeline, and the nozzle 8 is arranged on the main pipeline and is located directly above the cooktop. The nozzle can atomize the fire extinguishing agent stored in the container 3. In other embodiments, the first pipeline and the tap water pipeline 1 can also be respectively connected to the nozzle 8 to deliver the fire extinguishing agent and cooling water to the nozzle 8 respectively.

The temperature sensor 7, usually set directly above the stove, is used to measure the ambient temperature and automatically fuse when a fire occurs. Generally, the fusing temperature of the temperature sensor 7 is greater than 150 degrees Celsius.

Electric control box, inside the box is a control panel 14, an audible and visual alarm for external alarm signals, an alarm indicator 13, and a signal transmitter for communication with the user's mobile phone, property management monitoring equipment and other remote communication equipment 12. The control panel 14 is in signal connection with the temperature sensor 7, the emergency starting device 5, the gas air valve 10, the sound and light alarm, the alarm indicator 13, and the signal transmitter 12 respectively. Among them, by integrating all the control parts in the electric control box, the entire automatic fire extinguishing integrated system is more compact, does not occupy space, and is easy to install.

When a fire occurs in the kitchen equipment, the huge heat generated by the burning flame increases the temperature in the hood. When the temperature of the burning flame reaches 185°C, the temperature sensor 7 detects that the ambient temperature reaches the melting temperature, and the control panel 14 controls The gas control valve 10 is closed to cut off the gas supply. At the same time, the control panel 14 can respectively control the emergency starting device 5 to open and the gas cylinder 6 to work. The fire extinguishing agent is sprayed from the chemical bottle through the atomizing nozzle into the oil pan and fume hood, and It chemically reacts with burning oil to form a covering layer to isolate the air and extinguish the flame. When the mechanical control valve 4 is opened and the set time is reached, the water flow linkage control valve 2 is opened, so that in the event of a fire, the fire extinguishing agent is delivered first, and then the cooling water is delivered. The water can be sprayed on the stove and the smoke hood to make it Cool down to avoid re-ignition. The signal transmitting device 12 can send the fire alarm information to the user's remote communication equipment, such as an application APP of a smart phone, so that the user can learn the kitchen fire situation in time when a fire occurs, so that the user can take further actions. The sound and light alarm is also connected to the fire control center signal, which can feed back the fire signal of the home kitchen to the fire control center to provide an alarm. The alarm indicator 13 can give an audible and visual alarm when a fire occurs. As shown in Figure 2, after the temperature sensor detects that the ambient temperature reaches the pre-warning temperature, it sends a signal to the fire temperature sensing control panel, and the fire temperature sensing control panel controls the fire extinguishing device so that the fire extinguishing agent in the fire extinguishing agent storage bottle group is transported To the nozzle, perform the fire extinguishing operation, and control the gas control valve 10 to close at the same time. After the fire source is extinguished, the fire temperature sensing control panel controls the water flow linkage control valve to open, and controls the cooling water spray mechanism to supply cooling water, so that the stove can be cool down.

For the safety of the kitchen, the integrated automatic fire extinguishing system for home kitchens also includes an emergency starting device 5 and a manual starting device 11. The emergency starting device 5 and the manual starting device 11 are respectively electrically connected to the control panel 14. When a fire occurs, both can be Start the control panel 14 to start work. For example, when a fire occurs, when the ambient temperature measured by the temperature sensor 7 is still lower than the warning temperature, that is, when the fire is not strong, the user can turn on the control panel in advance by operating the emergency starting device 5 or the manual starting device 11 14 work, perform fire extinguishing operations.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those familiar with the technology to understand the content of the present invention and implement them accordingly, and cannot limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
