(6), the utility model master controller is provided with the time-delay halt circuit, a period of time of can delaying time after closing gas kitchen ranges just stops range hood, makes smoke pumping more thoroughly clean;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model structural representation such as accompanying drawing 1, accompanying drawing 2, shown in the accompanying drawing 3, include gas kitchen ranges 1, range hood 2, master controller 3, slave controller 4, plug valve handle 5, plug valve handle 6 and on the K switch 1 and the K2 that are adorned, magnetic valve 7, motor 8 and flame probe 9, flame probe 10, wherein master controller 3 and motor 8 are installed on the range hood 2, slave controller 4 and plug valve handle 5, plug valve handle 6 is installed on the gas kitchen ranges 1, flame probe 9, flame probe 10 is installed in respectively on two burners of gas kitchen ranges 1, and magnetic valve 7 is installed in the air inlet place of gas kitchen ranges.
The circuit diagram of master controller 3 of the present utility model and slave controller 4 such as accompanying drawing 4, shown in the accompanying drawing 5, when opening plug valve handle 5 or plug valve handle 6, K1 or K2 connect power supply and supply with slave controller 4, slave controller 4 electric work and by single-chip microcomputer and R12, T6, C1, the driving circuit for electromagnetic valve that R11 and T5 form is opened magnetic valve 7, pass through single-chip microcomputer when opening magnetic valve, T7, T8, B1, D3, C2, H1, the circuit that H2 and B2 form sends the combustion gas that high voltage pulse is lighted gas kitchen ranges 1 burner place, flame probe 9 or flame probe 10 pass through D1, R1, R2, R3, T1, T2, R5 or D2, R6, R7, R8, T3, R9, R10, the flame detection circuit that T4 and single-chip microcomputer are formed detects flare up fire, output one is kept signal and is kept the gas kitchen ranges normal combustion to driving circuit for electromagnetic valve after the single-chip microcomputer inter-process, single-chip microcomputer output control signal is transmitted on the master controller 3 of range hood 2 for the infrared transmitter of being made up of E and R13 after the normal combustion, on the master controller 3 by IC, the infrared radiation receiving circuit that C1 and single-chip microcomputer are formed receives transmitting of slave controller 4 and gives the motor-drive circuit starter motor of being made up of T1 and relay J 18 work after the single-chip microcomputer inter-process is exported a control signal.If single-chip microcomputer exported a shutdown signal after treatment and cuts out magnetic valve 7 to driving circuit for electromagnetic valve and do not export control signal and give radiating circuit when flame probe 9 or flame probe 10 and the flame detection circuit of being formed were surveyed less than flare up fire.The wind speed of motor 8 can be regulated by the air quantity regulating circuit of being made up of K1, K2, R1, R2, T1, J1, T2, J2 and single-chip microcomputer on the master controller 3; begin to work in the single-chip microcomputer internal timing system that starts on the slave controller 4 back slave controllers 4 in the countdown mode; timing is 30 minutes; slave controller 4 sends a control signal and closes magnetic valve 7 to driving circuit for electromagnetic valve when countdown finishes; thereby gas kitchen ranges is forgotten to close the fire protection, and timing also can be set by the user.
When using gas kitchen ranges cut-out tap valve handle 5 or plug valve handle 6, K1 or K2 disconnect, slave controller 4 is launched shutdown signal to master controller 3 by the infrared transmitter of single-chip microcomputer and R13 and E composition when K1 or K2 disconnection, after the infrared radiation receiving circuit of master controller 3 receives shutdown signal, close after 1 minute to motor-drive circuit control motor 8 delay workings through 1 minute time delayed signal of output after the single-chip microcomputer delay process, to allow indoor oil smoke take out totallyer.
Also can adopt radio wave or ultrasonic wave mode from the intelligent wireless control of control circuit and main control circuit, reception in the respective dashed frame shown in accompanying drawing 4 and the accompanying drawing 5 and radiating circuit can realize that then radio involves hyperacoustic wireless interactive control.Its control principle receives identical with the control of emission with the employing infrared ray.
If burner is more than two or can be by increasing or reduce switch and corresponding input solve when being less than two.
