Specific embodiment
As shown in Fig. 3, a kind of gas-cooker backfire control device, the vent line including gas-cooker, the main confession of vent line
Tracheae 21 is connected to outer gas source.Main 21 connected component air supply pipe of air supply pipe, branch air supply pipe are connected to burner 11.The connection of branch air supply pipe
Ignition switch 12, ignition switch 12 are connected to two gas-cooker air supply pipes 22, and a gas-cooker air supply pipe 22 is connected to outer mixing chamber 23,
Another gas-cooker air supply pipe 22 is connected to interior mixing chamber 24, and two mixing chambers are all connected to burner 11.Burner 11 is equipped with point
Fiery needle 31 and thermocouple 32 (being also blowout protection needle), ignition electrode 31 connect ignition switch 12, are equipped with electromagnetism in ignition switch 12
Valve 34,34 electric-connection thermal galvanic couple 32 of solenoid valve.
Such as Fig. 3,4, outer mixing chamber 23, interior mixing chamber 24 are designed with air inlet 5 (being also air register), and mixing chamber passes through combustion gas
Stove air supply pipe 22 supplies combustion gas, from there is air inlet 5 to supply air, is conveyed to burner 11 after mixing inside it.The study found that
When tempering, flame is burnt at air inlet 5.
So this gas-cooker backfire control device fixed temperature relay 4, the temp probe 41 of temperature relay 4 is located at
In the top of air inlet 5.Circuit communication between temperature relay 4 and solenoid valve 34, thermocouple 32, and temperature relay 4 is controlled
It makes the closure of the circuit, disconnect, temperature relay 4 is closed type.
In order to facilitate the fixation of temperature relay 4, the fixed fixing piece in the end of outer mixing chamber 23 or/and interior mixing chamber 24
42, fixed temperature relay 4 on fixing piece 42.
In order to facilitate the mixed proportion of regulating gas and air, hinged air regulating board 51 at air inlet 5.
The gas-cooker made of gas-cooker backfire control device can be single stove, or double stoves.
When single stove, it is equipped with one group of gas-cooker backfire control device, one group of burner 11.
Such as Fig. 3-5, when double stoves, set that there are two gas-cooker backfire control device, two groups of burners 11, two groups of gas-cookers
Backfire control device shares a main air supply pipe 21, and main air supply pipe 21 is connected to two groups of branch air supply pipes, every group of branch gas supply by threeway
Pipe is connected to one group of burner 11.
Normal condition, temperature relay 4 make the closing of circuit between solenoid valve 34, thermocouple 32；(just when temperature is higher
It is when generating tempering), temperature relay 4 detects the raised signal of temperature, by the disconnection of the circuit.In this way, solenoid valve 34 loses
Electricity, cuts off gas supply line, the fray-out of flame of burner and air inlet 5, and temperature relay 4 cannot detect the raised letter of temperature
Number, make the circuit communication between solenoid valve 34, thermocouple 32, and can work normally.The cutting of gas circuit is completed in this way.
Its working principle is that:
Igniting, thermocouple part like the prior art, only increase a temperature relay in tempering combustion zone
4, reinforce tempering protection.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those skilled in the art,
Without depart from that overall concept of the invention, several changes and improvements can also be made, these also should be considered as of the invention
Protection scope.
