Abstract
The utility model relates to a gas stove with a timed extinction device, which comprises a stove face rack, a gas switch and a burner which is provided with a pulse controller to realize ignition control and fire closing control. A timer is micro computer control, liquid crystal display and key operation type, and the timer is connected to the pulse controller by a transmission line to transfer a signal for timing to close the valve. Thermocouples are connected in parallel on an electromagnetic valve and arranged on a burner to realize flame-out security protection. Security of a furnace device is enhanced, timing precision is high, and use is more convenient. Timing operation is not only safe, but also burning can be avoided especially for boiling soup, boiling medicine, boiling water, cooking rice and steaming vegetables, and meal is more palatable.
Description
The utility model relates to a kind of gas furnace, particularly a kind of gas furnace with timing blanket.
Commercially available gas furnace does not generally all have regularly to close fiery device at present.Chinese patent discloses a kind of " gas-cooker with timing means " for No. 962302414, and it comprises kitchen range face frame, gas pipeline, burnt gas switch, air door and burner, and magnetic valve is connected on the preceding gas pipeline of burnt gas switch, and timer and magnetic valve are in series.It adopts mechanical timer, and timing uncertainty is true, and security reliability is relatively poor.Other has a kind of commercially available blowout protection gas-cooker, will continue during igniting by switch a period of time, and to guarantee that thermocouple burns the generation of heat back and enough keeps the electric current that magnetic valve does not take off valve, it is not too convenient to use.
The purpose of this utility model aims to provide a kind of simple in structure, accurate timing, esy to use, safe and reliable has a regularly gas furnace of blanket, to overcome the deficiencies in the prior art part.
The regularly gas furnace of blanket that has by this purpose design, comprise on boiler face frame, burnt gas switch, air door, burner, the gas pipeline and be serially connected with magnetic valve, its architectural feature is also to be connected with impulse controller on the magnetic valve, be provided with the time-delay holding circuit and the kick circuit that boosts in the impulse controller, to realize the igniting and the fire control system of closing; Timer links to each other with impulse controller by a transmission line, closes valve signal to transmit regularly, and timer is micro computer controlled standard, liquid crystal display, button operation.
Magnetic valve time-delay holding circuit is housed in the described impulse controller, and its output line is connected on the magnetic valve, and fire one is lighted and can be loosed one's grip like this, needn't wait for that thermocouple burns heat.Also be provided with the kick circuit that boosts in the described impulse controller, and an output line and magnetic valve are arranged and connect, to realize regularly closing fire.Described magnetic valve is installed in the valve body of burnt gas switch back, and on magnetic valve and connect thermocouple, thermocouple is contained on the burner, to realize flame-out safeguard protection.
The utility model adopts the blowout protection of thermocouple, magnetic valve, with the impulse controller igniting, keeps magnetic valve and cooperates magnetic valve to keep burning and realization blowout protection by thermocouple after several seconds.In addition by LCD computer control countdown timer, timing to after send signal, impulse controller is produced closes threshold voltage, close magnetic valve, realize regularly closing fire.It has strengthened the security reliability of stove and accessory greatly, the control of its liquid crystal display, computer, timing precision height, uses convenient, especially for Baoshang, pot medicine, heat up water, cook, steam dish, fixed cycle operator is safety not only, and can avoid burnt paste, makes food better to eat.
Accompanying drawing is the utility model one embodiment.
Fig. 1 is the present embodiment structural representation;
Fig. 2 is circuit theory diagrams;
Fig. 3 is system's control block diagram.
Referring to Fig. 1, it comprises that existing boiler face frame 7, gas pipeline 3, burnt gas switch 5, air door 6, burner 1, magnetic valve 4 are installed in the valve body of burnt gas switch 5 back, and on magnetic valve 4 and connect thermocouple 2, thermocouple is contained on the burner 1, and timer 9 is installed in burnt gas switch 5 one sides.Impulse controller 8 is connected on magnetic valve 4 and igniting pin and the battery case, by the microswitch control operation.
Referring to Fig. 2, the time-delay holding circuit is made up of triode P1, N1, P2, capacitor C 3, magnetic valve DT1 and triode P4, N2, P3, capacitor C 4, magnetic valve DT2.The kick circuit that boosts is made up of triode P6, transformer T2, capacitor C 10, voltage-stabiliser tube Z2, controllable silicon S2, magnetic valve DT2.Its operation principle is as follows: press the right switching knob, K switch 1 is connected, triode P1, P5 conducting simultaneously.The P1 conducting, capacitor C 3 is full of electricity at once, and triode N1, P2 conducting produce the electric current of keeping magnetic valve DT1; The P5 conducting, N3, transformer T1 starting of oscillation produce continuous high-voltage pulse igniting, and therefore, as long as one press gently, pulser can be lighted a fire continuously, can loose one's grip after lighting.Capacitor C 3 in the circuit, resistance R 2 are formed the RC circuit, to keep magnetic valve, burn heat until thermocouple RDO1 and keep the electric current of magnetic valve to keep burning by the thermocouple generation again.In case flame-out, thermocouple electromotive force disappears, magnetic valve takes off valve, turn-offs combustion gas, has realized safeguard protection.
Press left side switching knob, triode P4, P5 conducting simultaneously, circuit theory is the same.The sparking while, left way solenoid valve DT2 is kept by the RC circuit that resistance R 9, capacitor C 4 are formed, and is kept by left road thermocouple RDO2 then.
Timer can be set arbitrarily, and timing arrives, and can send a negative pulse and make triode P6 conducting, and P6, transformer T2 starting of oscillation give capacitor C 10 chargings.When charging voltage surpasses 10V, voltage-stabiliser tube Z2 and controllable silicon S2 conducting, the voltage on the C10 causes magnetic valve to take off valve by the electromagnetic valve coil back discharge, realizes regularly closing fire.
The present embodiment timer is selected the PIC16C54 single-chip microcomputer for use.
