Abstract
The utility model relates to a control device for the safe combustion and automatic ignition of gas range. The control device comprises a flame detecting device and a hypoxia state detecting device which individually control a pulsed high-voltage generator to ignite, a fire gas valve and a main fire gas valve to open and close after the comparison and confirmation of a signal processing controller according to the practical situation in combustion process; With safe and practical use, the utility model combines the functions of automatic ignition, valve opening, combustion state detection, automatic closing main fire gas valve when fire is extinguished, reignition and valve reopen, hypoxia state detection and control.
Description
The utility model relates to the safety device that detects burning and oxygen consumption situation in a kind of combustion gas tool combustion process and realize control automatically.
Before the utility model was made, combustion gas tool such as gas heater and gas cooker etc. did not all have the combustion position checkout gear, when igniting not or combustion process in when extinguishing kindling material because of wind or spilling water, coal gas is very easily overflowed and is caused danger.Though some gas apparatus of being furnished with the insurance measure can prevent that coal gas from leaking outside, can't realize lighting a fire again automatically and open and close air feed and burn.In addition, gas heater generally is installed in the space less toilet or kitchen, and the oxygen demand to water heater in the use has strict demand, in case the water heater oxygen demand is too much, when anoxic appearred in surrounding environment, human body just can produce danger because of anoxic.Present gas heater then lacks detection and automaton, stays hidden danger to safe handling.
The utility model provides a kind of collection to light a fire automatically and has opened valve, fired state detects, automatically close when kindling material extinguishes main internal heat valve and again igniting open valve, anaerobic condition detect and function such as control in the safety governor of one, to reach safety, the convenient purpose of using the combustion gas tool.
The purpose of this utility model realizes by following technical measures: controller is by power supply, pulsed high-voltage generator, flame probe and flame identification circuit, anoxic probe and anoxic identification circuit, signal processing controller, kindling material valve and driver, compositions such as main fire valve and driver.Flame probe is arranged at kindling material and main burner top, and the flame identification circuit inserts the signal processing controller input.The anoxic probe is arranged at burner top, and the anoxic identification circuit inserts the signal processing controller input.Pulsed high-voltage generator, kindling material valve driver and main fire valve driver are connected with the output of signal processing controller respectively.The flame identification circuit, the signal of anoxic identification circuit output provides signal respectively after signal processing controller is relatively confirmed, with the operating impulse high pressure generator, kindling material valve driver and main fire valve drive operation.In pulsed high-voltage generator work, the ignition signal lamp is bright.
Following the utility model structure drawings and Examples describe in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model electrical schematic diagram.
Fig. 3 is the utility model functional-block diagram.
Fig. 4 uses schematic diagram for the utility model on the combustion gas tool.
With reference to Fig. 1, all parts of controller all are assemblied in the big plastic casing of a perfumed soap 1.Seal with inserts 2 between each components and parts.3 is pulsed high-voltage generator among the figure, and 4 is the high voltage pulse output, (ignition tip), 5 is fixing hole and ground connection, and 6 is flame probe, and 7 is the anoxycausis detection probe, and 8 is the special-purpose integrated package of semiconductor, and 9 is circuit board, and 10 is electrode.Include power circuit in the foregoing circuit, flame identification circuit, anoxic identification circuit, signal processing controller integrated circuit, pulsed high voltage generator circuit, kindling material valve drive circuit, main fire valve drive circuit, (as Fig. 2).Referring to Fig. 3, Fig. 4, flame probe is arranged at the top of kindling material burner 12 and main burner 13.High voltage pulse output (igniter) is positioned at kindling material burner 12 tops.The anoxic probe is positioned at main burner 13 tops.After connecting starting-up signal switch 16, the electric pulse firing circuit is opened in the controller work that picks up counting automatically, and (this moment, ignition signal lamp 15 was bright), and open kindling material air valve 11 rapidly, light kindling material.After kindling material is lighted, will produce the electron stream of doing directed movement in the electric field that between burner and flame probe, is applied.The flame identification circuit with the signal input signal processing controller that records after, through relatively confirming output order, the main fire valve drive operation is opened main internal heat valve, main burner work.At this moment, circuit enters stable detection-phase, i.e. burning detects and the anoxic detection-phase.This moment, kindling material valve was in the closed position.By wind, when accidents such as spilling water were extinguished, the flame probe can detect signal, repeated above-mentioned igniting again, opened the valve events process by signal processing controller as main fire.When misfiring because of the air pressure deficiency kind, by promptly shutting down automatically after the timer control igniting several seconds, all gas circuits and circuit all are turned off.17 is dry battery power among Fig. 4.
When in the combustion process anoxia phenomenon taking place, flame is rubescent, and phosphorus content increases in the waste gas, and the resistance value that is produced between burner and anoxic probe will change.After the anoxic identification circuit was input to signal processing controller with signal, by handling the main fire valve driver, the kindling material valve driver was closed the two-way air valve, and while cut-out point ignition circuit.
The utility model automation detection means is complete, the control accuracy height, and it is computerized that the combustion gas tool is realized, improved the quality grade of combustion gas tool.After adopting anoxic and normal flame to detect control, the security performance of combustion gas tool is improved greatly.And machine volume is small and exquisite, and power consumption is little, and is moistureproof shockproof.Has good practical values.
Claims (2)
1, a kind of safe automatic gas tool controller, comprise power supply and pulsed high-voltage generator 3 and high voltage pulse output 4, it is characterized in that: it also includes flame probe 6 and identification circuit, anoxic probe 7 and anoxic identification circuit, signal processing controller, kindling material valve driver and kindling material air valve 11, main fire valve driver and main internal heat valve 14; The flame identification circuit is connected with the input of signal processing controller respectively with the anoxic identification circuit, pulsed high-voltage generator, and kindling material valve driver and main fire valve driver are connected with the output of signal processing controller respectively.
