Abstract

The utility model discloses a gas stove with a timing flameout controller, which comprises an electromagnetic valve arranged on the gas path of an impulse lighting type gas stove. A timing control button, time scales, and an indicating lamp for timing and using states are arranged on a control panel on the side of a lighting button. The interior of the gas stove is provided with a timing control circuit which comprises an electronic timer, an integrated circuit IC, a thermocouple return circuit, a transistor and a relay, wherein the thermocouple return circuit is connected with a switch K. The utility model has the control principle that the thermocouple return circuit is additionally provided with the switch, and the timing function is realized by the timer through controlling the switch. The gas stove with the structure can keep the timing function for a longer time, and the timed time can be regulated randomly. The gas stove has the advantages of accurate timing and convenient use.

Description

The gas furnace of the regularly flame-out control device of band

The utility model is a kind of gas furnace, specifically relates to a kind of gas furnace with the control of regularly stopping working.

The band of the known technology regularly gas furnace of flame-out control has the flame-out control of the timing of adopting the mechanical type air valve, and its shortcoming is that the timing controlled time is not long, inaccurate; The gas furnace that adopts electric timed unit is arranged, as the patent No. is the disclosed technology of patent of ZL99215774.9, its electric timed unit is made up of ignition switch, delay pulse generator, firing porcelain needle, electric valve, time controller etc., and it is to control the purpose that electric valve reaches time-delay control by the delay pulse generator; Though aforesaid way is simple in structure, easy to use, the time-controlled time still is restricted, and the time can not be oversize.

The purpose of this utility model is to provide a kind of timing accurate, and timing is regulated arbitrarily, and the control of sufficiently long timing can be provided, and original accident extinguishing constant gas furnace of function of holding one's breath automatically.

The utility model is to realize above-mentioned purpose in the following way: it is to be provided with magnetic valve on pulse sparking formula gas furnace gas circuit, set up a timing controlled button and be provided with time scale in sparking button one side of control panel, and be provided with regularly user mode indicator lamp, in gas furnace, be provided with timing control circuit, realize time switch by timing control circuit control magnetic valve.

Described timing control circuit comprises electronic timer, integrated circuit, thermocouple loop, triode, relay, is connected to a switch on the thermocouple loop, controls this switch by timer and realizes timing function.

Adopt the utility model of said structure can carry out continuous electronic timing control device, can carry out regularly well-done control for a long time.When not needing timing controlled, the well-done operation of all is as usual, opens gas furnace when needs are regularly well-done, and firepower is regulated, and then the corresponding scale of required well-done time is opened and be threaded to the timing controlled button and gets final product.When setting-up time has arrived, timer then cuts out gas circuit automatically and stops well-done, very easy to use.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model embodiment circuit theory diagrams.

The utility model gas furnace is by being to be provided with magnetic valve on pulse sparking formula gas furnace gas circuit, set up a timing controlled button and be provided with time scale in sparking button one side of control panel, and be provided with regularly user mode indicator lamp, in gas furnace, be provided with timing control circuit, this timing control circuit comprises electronic timer, integrated circuit, thermocouple loop, triode, relay, be connected to a K switch on the thermocouple loop, its control principle increases a switch in the thermocouple loop and timing function is to be realized by this switch of control by timer.

The timing controlled process of the utility model gas furnace is such: open timer connection power supply when the timing controlled button and start working, at this moment " regularly begin " the bright LED of indicator lamp ₂Indication regularly begins, in timing process, and timing ic IC ₁8 pin output electronegative potential, make triode BG ₁End IC ₂2,6 pin be in electronegative potential, thereby make integrated road IC ₂3 pin output high potential pass through resistance R ₇Make triode BG ₂Be in conducting state, but because triode BG ₁End, the relay fourth is in dead electricity is failure to actuate, regularly proceed, and when regularly finishing, IC ₂8 pin can export high potential, make triode BG ₁Conducting, this moment, relay J got electric adhesive, and the normally-closed contact k in control thermocouple loop disconnects, and made the gas circuit control magnetic valve on same loop close gas circuit because of losing in thermo-electromotive force, thereby fixed existing regularly flame-out function " regularly begins " indicator lamp LED when regularly finishing ₂Extinguish " regularly finishing " indicator lamp LED ₁Bright, indication regularly finishes.

Simultaneously, because integrated circuit I capacitor C ₁The high potential of 8 pin output pass through resistance R ₆Be added to IC ₂6 pin on, and 6 pin current potentials are because of capacitor C ₂Charging can not suddenly change IC ₂3 pin still export high potential, the continuation adhesive of guard relay J, the time about through 10～15 seconds, capacitor C ₂On current potential when being raised to certain value, IC ₂Counter-rotating, the output of 3 pin becomes electronegative potential by high potential, makes triode BG ₂End, the relay J dead electricity disconnects, and the normally-closed contact k in control thermocouple loop resets, and makes the thermocouple loop recover to be in normal dormant state.She Ji benefit is the total current that can significantly reduce on the circuit like this, to prolong the service life of battery.

Gas furnace of the present utility model can carry out the flame-out control of the continuous long-time timing more than 5 hours, as long as suitably select w and capacitor C ₁Numerical value just can realize that circuit design is very simple and practical.
