Description
Technical field
The present invention relates to a kind of gas combustion apparatus.It is specifically related to a kind of combustion gas deep fryer power-consumption control system.
Background technology
Combustion gas class stove is with the feature of the Portable belt of its uniqueness, it is suitable for the field usage not having alternating current power supply, but typically all its temperature can not be accurately controlled, reason is that it is owing to using combustion gas to do thermal source, so the cheap supply current typically selecting traditional thermocouple ever-burning flame to be Electromagnetic Control air valve, the precision of mechanical attemperating unit does not ensures again the Oil-temperature control as deep fryer etc, oil temperature is little higher, oil in oil cauldron is it is possible to understand spontaneous combustion, power with battery, it is big to there is again power consumption in electrical equipment control, and solenoid electric valve is difficult to the shortcoming turned off.
Summary of the invention
It is an object of the invention to provide a kind of combustion gas deep fryer power-consumption control system, its control accuracy is high, controls the low in energy consumption of device.
In order to achieve the above object, the present invention has a following technical scheme:

Detailed description of the invention
Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
See Fig. 1-Fig. 2, a kind of combustion gas deep fryer power-consumption control system of the present invention, by solenoid electric valve, anoxia preventer, temperature control equipment forms, described temperature control equipment is made up of bridge circuit, differential linear amplifying circuit, drive circuit, bridge circuit connects differential linear amplifying circuit, differential linear amplifying circuit connects drive circuit, drive circuit turns off inductance and the thermocouple of anoxia preventer, the coil tandem of solenoid electric valve by one, and described temperature control equipment uses 3V battery to power.The outfan of described differential linear amplifying circuit is provided with positive feedback shaping circuit.An arm in described bridge circuit is temperature detecting head, and this temperature detecting head is for detecting the temperature of combustion gas deep fryer.Described temperature detecting head is platinum wire resistance.Described temperature detecting head is arranged on bottom combustion gas deep fryer.Described parallel combustion gas is toppled over the circuit connection point of break off preventor and is all used soldering to connect.
When normally using, pressing button ignition switch, light in Chang Minghuo, Chang Minghuo burning ODS, ODS circuit and will produce micro voltage, supply and keep the adhesive of solenoid electric valve, make gas circuit open, keep normal supply, kitchen range are with regard to normal heating.When temperature rises to design temperature, the temperature detecting head connected in bridge circuit, just can detect, temperature detecting head is made by platinum wire resistance.nullWill output signal after platinum wire resistance detects temperature arrival design temperature，Signal amplifies through differential linear amplifying circuit，Again through positive feedback shaping circuit shaping，Form certain return difference，Make waveform steep，The switch conduction of drive circuit，Moment adds 3V voltage at major loop inductance L two ends，An induced potential and electric current will be produced at the two ends of inductance L，Relation according to di=-dv/dt，A reverse potential will be produced be added on major loop，Main circuit current is made to reduce，When electric current is less than the holding electric current of solenoid electric valve，Solenoid electric valve return，Gas circuit is closed，Prevent oil temperature from raising further，While turning off gas circuit，Light emitting diode in circuit is bright，Decline along with oil temperature，When dropping to divide into temperature spot，Light emitting diode goes out，Can again light a fire again heating，So oil temperature just can control between the temperature up and down set.And by experiment repeatedly, only by the circuit being arranged so as to, required control energy consumption is minimum, only needs the battery of a 3V.
During concrete installation operation:
1, during temperature control equipment is contained in a plastic casing, and seal with airtight and watertight padding.
2, display lamp is contained on guidance panel.
3, detection head is installed on pot bottom.
4, debugging time on/off inductance two end line interchangeable (changing polarity of voltage) with jump to display lamp bright time close solenoid electric valve.
Bridge circuit: it is the faintest for generally referring to measured parameter, it is necessary to measure this faint change with special circuit, the most frequently used circuit is exactly various bridge circuits, mainly has direct current and AC bridge circuit.The effect of bridge circuit: the resistance change rate Δ R/R of resistor disc is converted into voltage output, is provided to measure after amplifying circuit amplifies.
Obviously, the examples detailed above of the present invention is only for clearly demonstrating example of the present invention, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot all of embodiment be given exhaustive.Every belong to obvious change that technical scheme extended out or the variation row still in protection scope of the present invention.
