Abstract
A safe gas-cooker closing automatically when flameout. The gas-cooker comprises a housing, legs, liquid holding discs, pan supports, center fire covers, an outer fire covers, turn buttons, piezoelectric ceramic igniters and igniting air passages. A safety valve and a plug valve are arranged in a same valve body; a gas outlet is arranged on the safety valve body; an air intake and a valve port A are arranged inside the plug valve; a valve port B is arranged between the safety valve and the plug valve; and the plug valve and the safety valve are set to an unlatching state by pressing and turning the turn buttons.
Description
Technical field
The present invention relates to a kind of gas kitchen ranges, particularly a kind of flame-out automatic closed safe gas kitchen range belong to the cooker technical field.
Background technology
Along with the universal use of gas appliance, its security performance is also paid close attention to by the people day by day, the common eyes kitchen range of the gas kitchen ranges multidigit of Chu Shouing in the market, great majority do not have the flame-out protection device function.And in daily use owing to wind, overflow meal or suddenly provisional reason such as stop the supple of gas or steam, when burning and flame are extinguished simultaneously, can in very short time, combustion gas continue to leak, cause poisoning, meet fiery accident such as fried and take place, create greater casualties and accident for user's lives and properties.
Summary of the invention
The objective of the invention is to provide a kind of generation that prevents casualty accident above-mentioned in the existing kitchen range, propose a kind of flame-out automatic closed safe gas kitchen range, it sets up flame-out device of closing igniter automatically in general gas kitchen ranges.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of flame-out automatic closed safe gas kitchen range; it is mainly by shell; leg; drip pan; pot supporter; middle internal heat lid; external ring fire cover; igniter and flame-out protection device constitute; it is characterized in that flame-out protection device comprises magnetic tube; the memorial alloy switch; electromagnetic valve and plug valve; safety valve and plug valve are contained in the same valve body; be provided with valve port A that can connect with air inlet and the valve port B that is communicated with safety valve in the plug valve; the igniting gas circuit that also has valve port to be connected with piezoelectric ignition device connects; the other end of electromagnetic valve links to each other with the memorial alloy switch; in the airtight magnetic tube of memorial alloy switch, and on its valve body, be provided with the gas outlet.Near internal heat was covered during described memorial alloy switch was installed in by magnetic tube, it has pipeline to be communicated with electromagnetic valve, by the heating of middle internal heat lid burned flame, be under the memorial alloy switch high temperature fire low temperature and connect fiery closed condition, iron core in the excitation electromagnetic valve holds armature, and safety valve is opened.One end of described plug valve is provided with knob, by pushing and rotation the valve port B between safety valve and the plug valve is opened.
Beneficial effect: these kitchen range have switch and light the function of combustion gas, regulation and control gas flow.Particularly when the combustion gas tool in use owing to wind, meal are overflow, when suddenly provisional reason such as stop the supple of gas or steam is extinguished the burned flame accident, can be closed source of the gas automatically in very short time.Prevent the poisoning that continues to leak and cause because of combustion gas, meet the generation of fiery accident such as fried.These kitchen range mainly contain compositions such as flame-out protection device, plug valve, piezoelectric ignition device.Formed the blast tube of bivalve mouth by the safety valve in plug valve and the flame-out protection device, closed when any valve wherein and can cut off source of the gas.Flame-out protection device is made up of magnetic tube, memorial alloy switch and safety valve, and when main burner flame heat magnetic tube, the memorial alloy switch is under high temperature or low temperature to be connected or closed condition, and the work of excitation safety valve makes circuit be in opening.When the flame accident was extinguished, the memorial alloy switch cut out, and the valve port of safety valve automatic self-closing gas passage under its spring action has stoped combustion gas to leak.
Operation principle of the present invention is: when opening the switching point firearm, should at first push and promote counterclockwise the knob plug valve, safety valve all is in opening, and combustion gas flows to the main burner gas circuit of meanwhile lighting a fire and also opens, wait to hear " " when sound, piezoelectric ignition device is lighted flame automatically.Under this state knob is compressed, keep the several seconds, the flame of main burner just will be heated to operating temperature.Too early, safety valve does not also enter normal operating conditions if loose one's grip, and safety valve cuts out blast tube under its spring action.Should repeat above-mentioned opening process this moment.Turning knob adjustable fuel gas stream changes flame size.
