Abstract
An integral control device for soot suction machine and gas burner is provided, which comprises a singlechip input circuit and a singlechip output circuit. The input end of the singlechip is connected with a soot detector and a photoelectric control circuit; the photoelectric control circuit comprises a light sensitive diode and a light sensitive triode; the light sensitive diode is connected with the input end of the light sensitive triode; the output end of the light sensitive triode is connected with the input end of the singlechip; the output end of the singlechip is connected with a gas ignition control circuit; the gas ignition control circuit comprises a pulse transformer, a charging capacitor, a thyristor and a discharging pin. The utility model has the advantages that : the soot suction machine and the gas burner are controlled integrally; the soot suction machine can operate automatically when the gas turned is turned on. In addition, the gas burner has the function of automatic ignition when the flame extinguishes accidentally during the combustion, thus assuring the personal safety of user.
Description
Technical field
The utility model relates to a kind of range hood and gas range control device, particularly a kind of range hood and gas range integral type control device.
Background technology
The utility model is before the applying date, and range hood and gas range split control can not be opened range hood work automatically when opening gas range.Gas range does not have the automatic firing function when accident is extinguished in the gas-fired process yet, and unexpected extinguishing brings hidden danger with the personal safety to the user in the gas-fired process.
Summary of the invention
The purpose of this utility model provides a kind of range hood and gas range integral type control device with the automatic firing function when accident is extinguished in the gas-fired process.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises the single-chip microcomputer imput output circuit.The single-chip microcomputer input is connected with photoelectric control circuit with the oil smoke detector, photoelectric control circuit comprises photodiode and triode, photodiode is connected with the input of triode, the output of triode is connected with the single-chip microcomputer input, and the single-chip microcomputer output is connected with the coal gas ignition control circuit.The coal gas ignition control circuit comprises pulse transformer, charging capacitor, IGCT and spray point.
The beneficial effects of the utility model are range hood and the control of gas range integral type, can open range hood work automatically when opening gas range.Automatic firing function when gas range has in the gas-fired process unexpected extinguishing simultaneously brings guarantee to user's personal safety.
Description of drawings
The utility model is described in further detail below by accompanying drawing.
Accompanying drawing 1 is an electrical schematic diagram of the present utility model.
The specific embodiment
Consult Fig. 1.Single-chip microcomputer adopts PIC12C508 among the figure.
The utility model comprises the single-chip microcomputer imput output circuit.The single-chip microcomputer input is connected with photoelectric control circuit with the oil smoke detector, and the oil smoke detector adopts commercially available special-purpose smoke-detectors, embodiment smoke-detectors output switching signal.Adopt the smoke-detectors of output analog signal, need to be connected with single-chip microcomputer PIC12C508, or directly adopt the single-chip microcomputer that has the A/D translation interface by A/D converter.Photoelectric control circuit comprises photodiode and triode, and photodiode is connected with the input of triode, and the output of triode is connected with the single-chip microcomputer input, receives the triode skip signal.When turning on the gas-fire, coal gas do not lighted or the gas-fired process in accident extinguish, photodiode is in high-impedance state, makes the triode conducting that is attached thereto, to the triode output low level.The single-chip microcomputer output is connected with the coal gas ignition control circuit.The coal gas ignition control circuit comprises pulse transformer, charging capacitor, IGCT and spray point.Detecting in the gas-fired process accident at single-chip microcomputer extinguishes, output pulse signal, boost through first pulse transformer and to reach the pulse signal of 120V for peak value, charge to electric capacity, make the IGCT discharge, secondary side at second pulse transformer induces the 5-10KV high pressure, by the spray point point discharge, and the some coal gas.
