Description

Intelligent Kitchen Safety System And The Mananging Method Thereof

The present invention relates to an intelligent kitchen safety system and an operating method thereof, and more particularly, it is possible to set not only fire detection but also events such as operation/stop of electric range as notifications, and when a set event occurs, sequentially set to designated people By sending a notification until the event is resolved, it is possible to check the situation with CCTV and take appropriate measures to minimize safety accidents caused by negligence or damage caused by malfunction of the detector. It relates to a new type of intelligent kitchen safety system and its operation method that can be easily installed without special construction by connecting the main controller and the power cut-off module wirelessly and operating.

In general, due to frequent malfunctions of the existing kitchen fire detectors, the overall cost is increasing. In addition, the occurrence of fires is increasing due to the expansion of the spread of electric stoves. In addition, there are no commercial products that can prevent fires in electric stoves. In addition, it is necessary to consider the economic loss due to the increase in fires caused by companion animals.

Existing commercial fire detection or gas shutoff systems simply depended on whether or not the fire detection sensor was detected, so malfunctions were frequent in various situations.

A safety device that automatically/remotely cuts off the power of an electric range has not been commercialized.

Let's look at the problems of the existing kitchen fire prevention system.

First, a general fire detection system is a single fire detector that detects smoke and heat generated during cooking in the kitchen or indoors and sounds an alarm. In most cases there is

In addition, the malfunction of the detector is very frequent, so that an actual fire cannot be prevented after the detector is turned off, or the fire department is in vain.

In addition, products that prevent fires by shutting off gas in the gas range when smoke or temperature are detected are sold, but products that can prevent fires in electric ranges are not.

On the other hand, as the spread of electric stoves increases, the number of fire accidents caused by electric stoves is also increasing. In 2016, fire accidents caused by electric stoves accounted for 5.2% of all kitchen equipment fires, but more than doubled to 11.8% in 2019, and since 2018, it is the second largest cause of kitchen equipment fires after gas stoves.

Increased fires caused by pets

Recently, more and more households have companion animals, and among the causes of fires, the number of fire accidents caused by pets operating a touch-type electric stove is increasing. In particular, while the owner is away from home, or while sleeping, pets such as cats pass over the electric stove and turn on the power to cause a fire.

Waste of firefighters due to malfunction of fire detectors

A fire detector is the primary response to a fire. When a fire occurs, it detects it and sounds an alarm immediately. It also plays a pivotal role in the automatic fire detection system.

However, malfunctions of existing fire detectors often occur. When the alarm sound of a fire detector goes off, citizens usually think it is a malfunction and do not evacuate but wait for the alarm sound to go out quickly. As a result, it is not possible to respond quickly to actual fire accidents, resulting in great damage. There have been over 50,000 incidents of dispatches due to malfunctions of firefighting facilities nationwide over the past three years, and it is urgent to prepare countermeasures because it can result in wasting firefighting administrative power and inability to properly respond to emergency situations such as actual fires.

Therefore, in line with the changes in the kitchen environment, it is possible to prevent fires caused by electric stoves as well as gas stove fires. However, there is a need for a system that can reduce social costs due to device malfunction.
