Description
Technical field
The utility model relates to a kind of control circuit, especially a kind of combustion gas steam box control circuit.
Background technology
Along with continuous progress in science and technology; The combustion gas heating technique is also constantly developed, and wherein the combustion gas steam box is is also constantly researched and developed and produced as a kind of of gas-operated thermal bath facility, yet traditional steam box generally adopts the ball float water inlet; Be machinery control; Igniting is igniting by hand, and whole operation is cumbersome, nor safety; Existing electrical equipment control combustion gas steam box is because circuit control system is perfect inadequately; Its control circuit generally only has air-introduced machine, pulse ignition device and gas electromagnetic valve; Can adopt the fuel gas buring heating to heat up water; But can't automatic water supplement and do not have the excessive low water level protection function, cause security incident but also be easy to generate gas leakage.
Summary of the invention
The utility model provides a kind of easy to operate in order to solve defective and the deficiency that above-mentioned prior art exists, and can prevent gas leakage, safe combustion gas steam box control circuit simultaneously.
The technical scheme of the utility model: a kind of combustion gas steam box control circuit; Comprise interconnective power supply and control circuit board; Be connected with condensate tank of dehumidifier, entering water electromagnetic valve, air-introduced machine, pulse ignition device, gas electromagnetic valve, induced emission device, induction feedback device on the said control circuit board; Said condensate tank of dehumidifier is connected with air-introduced machine with entering water electromagnetic valve respectively; Said air-introduced machine also is connected with pulse ignition device with gas electromagnetic valve respectively, and said pulse ignition device also is connected with the induced emission device, and said induced emission device is connected with the induction feedback device.
Preferably, be connected with blast switch on the said gas electromagnetic valve, said blast switch is connected with control circuit board.
The utility model connects condensate tank of dehumidifier and entering water electromagnetic valve on control circuit board, it can be intake automatically, and is easy to operate; Induced emission device and induction feedback device are set simultaneously, make it can prevent gas leakage, improve security.
Description of drawings
Fig. 1 is the circuit block diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but be not restriction the utility model protection domain.
As shown in Figure 1; A kind of combustion gas steam box control circuit; Comprise interconnective power supply and control circuit board; Be connected with condensate tank of dehumidifier, entering water electromagnetic valve, air-introduced machine, pulse ignition device, gas electromagnetic valve, induced emission device, induction feedback device on the control circuit board, condensate tank of dehumidifier is connected with air-introduced machine with entering water electromagnetic valve respectively, and air-introduced machine also is connected with pulse ignition device with gas electromagnetic valve respectively; Pulse ignition device also is connected with the induced emission device, and the induced emission device is connected with the induction feedback device.Be connected with blast switch on the gas electromagnetic valve, blast switch is connected with control circuit board.
The utility model operation principle: start power switch, condensate tank of dehumidifier carries out water level detecting, if detect less than water level, starts entering water electromagnetic valve immediately, and the effect of excessive low water level protection anti-dry is played in water inlet automatically; When water level arrives low water level, explain possessed burning condition, air-introduced machine begins to start; In 6 seconds of prepurge before burning (prevent combustion gas from gathering, cold quick-fried phenomenon takes place), pulse igniter begins igniting then; Gas electromagnetic valve is opened simultaneously, and combustion gas runs into spark and takes fire.In the time of burning, the signal of the induced emission end of induced emission device emission is delivered to the induction feedback device through burned flame: if burning is normal, and flame stabilization, signal will remain unchanged always; Like the unexpected burn-out of middle flame, signal also will interrupt so, and solenoid valve for gas will cut off combustion gas automatically after the interrupt signal, thereby prevent the accidental release of combustion gas and security incident takes place.If continue operation, need powered-down to wait for after about 30 seconds and restart power switch, repeat above process.
The utility model connects condensate tank of dehumidifier and entering water electromagnetic valve on control circuit board, it can be intake automatically, and is easy to operate; Induced emission device and induction feedback device are set simultaneously, make it can prevent gas leakage, improve security.
