Description
Technical field
The present invention relates to a kind of safe automatic ignition system of gas-cooker, belong to combustion gas firing device class.
Background technology
Existing gas combustion range ignition has two kinds:
A kind of people of being start burnt gas switch on one side, Yi Bian use other as lighter, fire maker, means such as match are lighted combustion gas, and the work that this way needs two hands of user to light a fire synchronously and open burnt gas switch is cumbersome and dangerous.
Another kind is by the piezoelectric ceramics ignition mechanism, and by operator's switching on the ignition circuit when pushing button, so each igniting all needs the user to push button a period of time, also bothers; This is the ignition structure that generally adopts at present.
Simultaneously, safe handling for gas-cooker, existing gas-cooker leakage preventing device is to utilize temperature monitoring equipment is installed on kitchen range, when temperature is crossed the effect that automatic disconnection burnt gas valve when low is realized anti-leak, perhaps, make checkout gear with photodiode, the characteristic of utilizing photodiode internal resistance under the infra-red radiation of flame to descend.But these two kinds of devices are all affected by environment bigger, and wrong report easily.
Can think in sum: along with the generally use of combustion gas in living at home, the many potential safety hazards in the combustion gas use appear in the fatigability wearing and tearing of the mechanism's parts in regular meeting occurs owing to the Gas appliance use after the improper or permanent use.
Therefore, solution needs the user to push when having the dangerous of gas ignition device and igniting now and to the trouble that the people brings, realizes lighting a fire automatically; Solve the unstability and the easily wrong report property of existing gas-cooker device for preventing leakage, become gas-cooker user's expectation.
Summary of the invention
Purpose of the present invention: aim to provide a kind of safe automatic ignition system of gas-cooker, need the user to push when being used to solve the dangerous of existing gas ignition device and igniting and, realize igniting automatically to the trouble that the people brings; Also solve the unstability and the easily wrong report property of existing gas-cooker device for preventing leakage simultaneously.
The safe automatic ignition system of this gas-cooker, comprise burner dish A, gas pipeline B, fire maker, battery and valve, it is characterized in that: among the gas pipeline B, set gradually the valve 5 that is connected the valve 7 on the knob of kitchen range top surface and controls forwards, backwards according to source of the gas by gas sensor 2; Inner ring at the nearly burner dish of kitchen range gas outlet A is provided with fire maker 3; Photo resistance 4 is established in outer ring at burner dish A; Gas sensor is installed near the knob, and siren 1 is installed on the knob.
The combination of gas sensor valve, fire maker 3, the photo resistance 4 be made up of gas sensor 2, valve 5 all insert in being connected with the circuit of battery, and also have one in the circuit by the switch 6 of knob lower end by lever control.
Described gas sensor 2 can be selected the QM-N51 gas sensor of outsourcing for use, its use of connecting with a resistance that plays sensitivity adjustment in usually using.
The safe automatic ignition system of this gas-cooker that proposes according to above technical scheme needed the user to push when both having solved the dangerous of existing gas ignition device and igniting and to the trouble that the people brings, realized igniting automatically; Also solve simultaneously the unstability of existing gas-cooker device for preventing leakage and the defective of easily wrong report property, for the safe handling of gas kitchen ranges provides an effective technology scheme.

Accompanying drawing 1 is a system construction drawing of the present invention;
Accompanying drawing 2 is a circuit structure diagram of the present invention.
Among the figure: 1-alarm 2-gas sensor 3-fire maker 4-photo resistance 5-valve 6-switch
The specific embodiment
The safe automatic ignition system of this gas-cooker as shown in the figure, it is a kind of inventive improvements to existing gas combustion range ignition mechanism.The safe automatic ignition system of this gas-cooker, comprise burner dish A, gas pipeline B, fire maker 3, battery and valve, it is characterized in that: among the gas pipeline B, set gradually valve 7 that is connected on the knob of kitchen range top surface and the valve of controlling by gas sensor 5 forwards, backwards according to source of the gas; Inner ring at the nearly burner dish of kitchen range gas outlet A is provided with fire maker 3; Establish photo resistance 4 in the outer ring of burner; Gas sensor 2 is installed near the knob, and siren 1 is installed on the knob.
Gas sensor valve, fire maker 3, the photo resistance 4 be made up of gas sensor 2, valve 5 all insert in being connected with the circuit of battery, and also have one in the circuit by the switch 6 of knob lower end by lever control.
Further provide the course of work of the safe automatic ignition system of this gas-cooker below in conjunction with accompanying drawing:
Fig. 1 is the safe automatic ignition system schematic diagram (battery in circuit and the circuit, telegraph key etc. do not draw, and show) of gas-cooker in circuit diagram.Valve 7 that is connected on the knob of kitchen range top surface and the valve of being controlled by gas sensor 5 are arranged before and after among the gas pipeline B successively.The kitchen range gas outlet goes out inner ring fire maker 3, and there is photo resistance 4 outer ring.Gas sensor is installed near the knob.Siren 1 is installed on the knob.Gas sensor valve combination, sparking 3, the photo resistance 4 be made up of gas sensor 2, valve 5 all insert in being connected with the circuit of battery, and also have one in the circuit by the switch 6 of knob lower end by lever control.
Described gas sensor 2 can be selected the QM-N51 gas sensor of outsourcing for use, its use of connecting with a resistance that plays sensitivity adjustment in usually using.In smog and gas concentration lwevel increase, the electrical conductivity of this gas sensor 2 increases, and the voltage that plays the resistance output of sensitivity adjustment also can increase.
Fig. 2 is the circuit diagram of automatic igniting safety gas cooker.The combination of gas sensor valve, fire maker 3, photo resistance 4, siren 1 are linked in the circuit.The gas sensor valve combination can be when detecting the imflammable gas concentration over-standard cut-off switch and valve-off 5 closed alarm circuit simultaneously, start siren, detecting imflammable gas concentration just often Closing Switch and Open valve, simultaneously breakage alert device place circuit.
When the user brought into use kitchen range, the user rotated knob, and valve 7 is opened, while Closing Switch 6, this moment, gas sensor did not detect imflammable gas, and valve 5 is opened, photo resistance 4 does not detect flame, closing of circuit, combustion gas is lighted in fire maker work, flame appears, it is big that the photo resistance resistance becomes, and fire maker quits work, and igniting finishes automatically.
When kitchen range were worked, if flame is gone out by wind, the photo resistance value can reduce immediately, started fire maker, and combustion gas is lighted in igniting again, and photo resistance becomes big because of detecting the flame resistance, and fire maker quits work.Change does not need to carry out manual intervention again and kitchen range is worked on when flame is gone out by wind because of carelessness like this.
