Description

Cooking stove igniting and energy saving device

Technical field:

The utility model relates to a kind of cooking stove igniting and energy saving device, is applicable in the hotel, hotel, dining room, school, factory, has the size of automatic control fire, stops empty the burning fully, and accident extinguishing can cut off source of the gas automatically and stop gas leakage.

Background technology:

At present, along with energy prices rise steadily, be again non-renewable, energy savings is increased work efficiency very urgent, and the energy-conservation ignition installation of cooking stove also constantly occurs, its product is filled the buyer's market successively.For example: it is that two optoelectronic switches are installed on the kitchen range top with automatic igniting and energy saving device that the utility model patent of the patent No. 200420052638.1 discloses a kind of cooking stove, and when the cook was placed on pot on the pot circle, light was kept off, optoelectronic switch is just controlled magnetic valve and is opened, control the action of respective point ignition circuit simultaneously, light cooking stove, igniter is worked always, when cook's dish delivery, flavouring material when cleaning a pot, is taken down the pot circle to pot, optoelectronic switch is excited by high light and just controls closed electromagnetic valve, simultaneously the cut-out point ignition circuit.Cooking stove quits work, so repeatedly, just realize pot to fire to, pot go out from fire.Its defective is: there is very big potential safety hazard in its sparking mode, and its sparking mode is that main air valve was opened after pot was put, the igniter igniting, the deflagration easily of the main fire of direct-fire combustion, igniter is lighted a fire always influences the igniter life-span, and igniter continues the easy deflagration of igniting behind this product accident extinguishing.Can not close gas check valve, the national requirements accident extinguishing is closed source of the gas now.

Summary of the invention:

The utility model purpose is to provide a kind of cooking stove igniting and energy saving device, and this device, is put pot, played pot in the cooking process with pot, and the photoelectric sensor high-low level comes output switching signal, controls magnetic valve and igniter.Accident extinguishing can be closed source of the gas the very first time, prevents gas leakage, causes unsafe factor.This installs simple installation, and more reasonable structure makes things convenient for the cook to operate, and is applicable to various fuel gas.

In order to realize above-mentioned task, the utility model adopts following technical measures:

Cooking stove igniting and energy saving device is by transmitter, receiver, ever-burning flame magnetic valve, igniting pin, inductive needle, controller, igniter are formed, when main thermoelectricity magnet valve is put on the pot circle when pot, signal is cut off between receiver and the transmitter, the firearm igniting of controller control point, the ever-burning flame nozzle is opened, flame detection circuit is started working, after inductive needle detects ever-burning flame, signal is passed to controller, and controller control main fire valve is opened, and igniter stops igniting, the time-delay of ever-burning flame magnetic valve was closed in 5 seconds, entered normal operating conditions.If because accidental cause causes main fire to extinguish, inductive needle detects less than flare, just igniter igniting again again, the ever-burning flame magnetic valve is opened, if still misfired in 8 seconds, main fire valve valve kept burning day and night all cuts out, and alarm equipment alarm is stopped gas leakage.When pot is taken from the pot circle, transmitter and receiver signal conduction, the main fire valve closed electromagnetic valve accomplishes promptly repeatedly that so back and forth pot arrives to fire, pot puts out from fire.

The utility model has the advantages that: this apparatus structure is simple, and simple installation is easy to operate, the energy-conservation energy, safe ready.Its sparking mode is high-tension ignition, and has advanced flame detecting device, puts ever-burning flame earlier, and after inductive needle was sensed ever-burning flame, main fire valve was opened, and igniter cuts out, and stops igniting, and the 5 seconds ever-burning flames of delaying time are closed.If accident is extinguished, inductive needle is responded to less than behind the fire, igniter igniting 8 seconds, if still can't light, closed electromagnetic valve prevents gas leakage.

Description of drawings:

Fig. 1 is a cooking stove igniting and energy saving apparatus structure schematic diagram

Fig. 2 cooperates schematic diagram for Fig. 1.

The specific embodiment:

According to Fig. 1, Fig. 2 as can be known, signal generation apparatus is made up of transmitter 1 and receiver 2.Transmitter 1 and receiver 2 are installed in the kitchen range mouth outside, and can be placed on the kitchen range mouth upper pan body 6 partition signal locations.Three pins are installed on burner 18 next doors, ever-burning flame nozzle 5 is connected with magnetic valve 7 by pipeline 11, downwind is installed inductive needle 4, inductive needle 4 is connected with controller 10 by high temperature resistant wire 15, distance is that 8-10 millimeter one side is installed igniting pin 3, and igniting pin 3 is connected with igniter 9 by high temperature resistant wire 14, and igniter 9 is connected with controller 10 by lead 17, controller 10 is connected with lead high temperature resistant wire 15, apart from ever-burning flame nozzle 2-4 millimeter.Be connected with main gas tube 11 at ever-burning flame nozzle 5, magnetic valve 7.8 is installed respectively on the main gas tube 13, magnetic valve 8 is connected with main gas tube 13 with pipeline 12 respectively, magnetic valve 7 is connected with trunk line 13 with pipeline 11 respectively,

magnetic valve

7,8 is connected with controller 10 by

lead

16,19, is used to control the fuel gas break-make.Igniting pin 3 is connected on the isolating high-pressure ignitor 9 by high temperature resistant wire 14.Inductive needle 4 is connected on the controller 10 by high temperature resistant wire 15, and controller 10 is connected with

lead

16,17,19.

When this device used, frying pan body 6 was placed on the pot circle, and signal generation apparatus transmitter 1 is cut off with receiver 2, and this signal is passed to controller 10, and controller 10 indication magnetic valves 7 are opened.Igniter 11 igniting, flame detection circuit is also started working, and after inductive needle 4 detects flare, passes to controller 10, controls main fire valve 8 and opens, and igniter 9 cuts out, and the 5 seconds magnetic valves 7 of delaying time cut out.Cooking stove enters normal running.When pot leaves the pot circle, receiver 2 and transmitter 1 conducting, this signal is passed to controller 10, and controller 10 indication magnetic valves 8 cut out, and fire extinguishes.During normal use, if owing to water extinguishes fire, and inductive needle 4 is responded to less than flare at this moment, and inductive needle 4 is passed to controller 10 to signal, and controller 10 indication magnetic valves 8 cut out, and prevent gas leakage.
