Description

Emergency flameout device for gas stove

Technical Field

The utility model belongs to the technical field of kitchen utensils, and particularly relates to an emergency flameout device for a gas stove.

Background

When the gas stove works, 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 primary air), the mixed gas is sprayed out from the fire hole of the distributor and is ignited by the ignition device to form flames (the air required by the combustion is called secondary air), and the flames are used for heating cookers arranged on the pot support.

The window can often be opened in the kitchen in the family for the ventilation, just so lead to when using the cooking utensils to cook, gas flame can be along with the wind that outdoor blowing comes incessantly sways, if when flame is steady, the user does not notice opening of window, has left the kitchen, at this moment outdoor having scraped wind, will make flame begin to sway, if the next door of cooking utensils is put inflammable, will lead to the fire, the conflagration breaks out, current kitchen extinguishing device can only put out a fire after the conflagration takes place, can not prevent in advance.

Therefore, the need for an emergency flameout device for a gas cooker is very necessary.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides an emergency flameout device for a gas stove, which solves the problem that the existing kitchen fire extinguishing device can only extinguish fire after a fire disaster happens and cannot prevent the fire in advance. The utility model provides a gas cooking utensils emergency flameout device, includes the top of a kitchen range, its characterized in that, the upper surface of top of a kitchen range is equipped with the combustor, one side of combustor and the one corner that is located prime number top of a kitchen range upper surface are equipped with ultrasonic wave wind speed sensor, the periphery of combustor is and encircles and evenly be equipped with temperature sensor, the downside of top of a kitchen range is equipped with the work box, one side of work box is fixed with the controller, the lower extreme of combustor passes the inside of work box through the gas pipe and connects with the gas of work box one side and be connected, the gas pipe is located be connected with solenoid valve in the inside position of work box.

The upper surface of the ultrasonic wind speed sensor and the upper surface of the combustor are located on the same horizontal line, the distance between the ultrasonic wind speed sensor and the combustor is 20-25 cm, and the ultrasonic wind speed sensor is electrically connected with an input interface of the controller.

The temperature sensors are more than four and are embedded on the upper surface of the cooking bench at intervals and positioned on the periphery of the combustor, the distance between each temperature sensor and the combustor is 10cm-15cm, and the temperature sensors are electrically connected with the input interface of the controller.

The electromagnetic valve is electrically connected with an output interface of the controller, the controller adopts a single chip microcomputer as a core, and the controller, the temperature sensor, the ultrasonic wind speed sensor and the electromagnetic valve are all connected with a power supply used by a firing switch in a cooking bench.

Compared with the prior art, the utility model has the following beneficial effects:

1. according to the arrangement of the temperature sensors, the temperature sensors surround the periphery of the combustor, the temperature around the cooking bench can be detected simultaneously, the temperatures of the temperature sensors at different positions are compared, and whether the combustion of flame is stable or not and whether the heat radiation is uniform or not can be judged.

2. According to the arrangement of the ultrasonic wave speed-division sensor, the height of the ultrasonic wave speed-division sensor is the same as that of the combustor, so that the air speed/air volume blown through the combustor can be detected, and the influence of the blown air flow on flame can be avoided.

3. The utility model discloses solenoid valve's setting, when flame is unstable, can cut off gas switch, can avoid preventing the emergence of conflagration because the inflammables near the combustor is ignited to flame unstability, improves the security of using.
