TECHNICAL FIELD
[0001] The present disclosure relates to a gas appliance, and more specifically, to a
smart gas stove with a control system and method for controlling gas flow and disconnecting
a burner automatically in case of liquid spillage and gas leakage.
BACKGROUND
[0002] Background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the information
provided herein is prior art or relevant to the presently claimed invention, or that any
publication specifically or implicitly referenced is prior art.
[0003] Gas appliances, which are the device burning gas to perform a specific
function, such as gas water heater, gas stove, gas clothing dryer and gas fireplace, have a high
level of safety issue in home life. However, aging and malfunction are the main problem that
causes danger in running of the gas appliance, and they have to be detected immediately and
to get fixed or stopped.
[0004] While easily achieved in gas appliances, simmer temperatures have until now
been complicated issues for gas cooking apparatus. Conventional gas appliances are generally
operated by using manually activated mechanical actuator knobs, with infinitely varying
settings of the flow of gas by rotating associated gas proportional valves.
[0005] Currently large number of household use simple burner for their cooking
activities. However, sometime during boiling of liquids or baking of any food will results into
spill of liquid on the burner. It leads to forcefully closing of burning fire on the burner. It
results into leakage of gas. In parallel if other burner are also working then it leads to fire at
the same place. The liquid coming out of the burner will scattered under the gas burner in
household. Further, a small leak may gradually build up an explosive concentration of gas,
leaks are very dangerous. In addition to causing fire and explosion hazards, leaks can kill
vegetation, including large trees, and may release powerful greenhouse gases to the
atmosphere.
[0006] Thus, in view of the above and other existing issues available in the
conventional burner of gas appliances, there exists a dire need to provide an efficient,
effective and improveda smart gas stove with control system and method for controlling gas
flow and disconnecting a burner automatically in case of liquid spillage and gas
leakage.Further, there is also a need of a gas burner control system and method for
disconnecting the burner automatically in case of liquid spillage and gas leakage.
Furthermore, there is a need of a gas burner control system, which enables the user to control
the operation of the gas burner and regulates the intensity of flame without approaching the
burner body of the gas burner. Additionally, there is a need of a gas burner control system,
whichavoids excess blocking of burner due to spill of material.
[0007] In conclusion, the prior art obviously has shortcomings in actual use and is
inconvenient, so it is necessary to improve.

point in a mesh-like structure at bottom of each burner.
[0041] In another embodiment, when a liquid spills from the pot placed on a burner,
the liquid gets collected in the tray attached on the lower side of burner, wherein the liquid
7
collected in tray leads to activate the electrical circuit created via the contact points and a
signal is transmitted to the microcontroller to deactivate the gas supply to the concerned
burner.
[0042] In another embodiment, when gas leakage detector detects leakage of gas than
