Description

Gas-cooker, integrated gas-cooker magnetic induction hall rotary switch view pilot lamp

Technical Field

The invention relates to the technical field of indicator lamps, in particular to a gas stove and an integrated gas stove magnetic induction Hall rotary switch landscape indicator lamp.

Background

Gas cookers and integrated gas cookers refer to kitchen appliances heated by direct fire with liquefied petroleum gas (liquid), artificial gas, natural gas and other gas fuels. The popular degree of the gas stove and the integrated gas stove is unknown, but a passing concept is difficult to see.

When the gas stove and the integrated gas stove work, gas enters the stove from the gas inlet pipe, enters the stove head through the adjustment of the gas valve (the adjustment is carried out by a user through a knob), and simultaneously mixes a part of air (the part of air is called as primary air), the mixed gas is sprayed out from the fire holes of the distributor and is ignited by the ignition device to form flames (the air required during combustion is called as secondary air), and the flames are used for heating cookers arranged on the pot support. The gas stove is in a kitchen for a long time and the installation position of the gas stove is extremely difficult to clean. The current knob type indicating lamp needs to use a magnet for induction control, but the magnet has the phenomenon of demagnetization; that is, after the magnet is used for 7-8 years, the magnetic induction may be weakened, so that a signal error of the receiving device (the magnetism may cause the length of time along with factors such as temperature, use frequency and humidity) may occur, and an error instruction is issued, so that the actual opening degree of the gas valve cannot be known.

Therefore, how to provide an indicator light which has a long service life and can monitor the opening of the gas valve in real time is a problem that needs to be solved urgently by those skilled in the art.

If a plurality of switch knobs are arranged on the gas equipment, each knob can independently control the corresponding indicator light to be turned on/off, and the corresponding indicator light is not influenced mutually.

2) The user can know the on/off state of the corresponding gas valve body and the burning/extinguishing state of the burner clearly through the color state of the indicator lamp, and even judge the fire size/small state of the burner through the change of the lighting condition of the indicator lamp when the knob switch of the gas valve body is rotated. Especially when the gas oven uses the door of frying pan or gas oven to close, the user can not directly see the burning state of combustor, can judge the burning/extinguishing state of combustor and the size of the intensity of a fire according to the condition state of lighting up of pilot lamp this moment, and this uses to bring very big convenience for the user.

3) The gas valve body switch knob is arranged on the gas valve body and used for controlling ignition and large and small fire adjustment of gas equipment (such as a gas barbecue oven, a gas cooker, a gas oven and the like).
