Refer to Fig. 1, the gas oven with temperature sensing function of an embodiment of the present utility model comprises a stove originally
Body 10, one temperature sensor 20 and a gas controller 30.Stove body 10 comprises a combustion chamber to heat a pan 100.
In the embodiment shown in Fig. 1, combustion chamber comprises the inner ring combustion chamber 11a and an outer shroud combustion chamber 11b being substantially arranged concentrically.But no
Being limited to this, combustion chamber also can comprise the combustion chamber of multiple configuration arranged side by side.
Temperature sensor 20 comprises thermopile sensor 21 and a signal processor 22.It is understood that thermoelectricity
Heap sensor 21 is the infrared ray that sensing pan 100 is radiated in a non-contact manner, and exports a sensing signal.Signal transacting
Device 22 is electrically connected with thermopile sensor 21.Signal processor 22 processes 21 output sensing signals of thermopile sensor, and
Export a control signal.In the embodiment shown in Fig. 1, temperature sensor 20 is disposed on the central authorities of inner ring combustion chamber 11a, and refers to
To the bottom of pan 100, to sense the infrared ray that pan 100 is radiated.But it is not limited to this, in an embodiment, TEMP
Device 20 can be set up in parallel with combustion chamber, i.e. by combustion chamber, and points to the bottom of pan 100.After the detailed construction of temperature sensor 20 is held
Explanation.
Gas controller 30 is electrically connected with signal processor 22, and the control signal that basis signal processor 22 is exported
Adjust a gas flow of supply combustion chamber.For example, gas controller 30 is connected with gas pipeline Gp, the one of gas pipeline Gp
End connects gas source G, and the other end connects combustion chamber 11a, 11b, and so, it is defeated that gas controller 30 gets final product basis signal processor 22 institute
The control signal gone out adjusts gas flow.In an embodiment, gas controller 30 can be analog gas controller or multistage
Formula gas controller.For example, analog gas controller can be the methane monitor of Clippard company ET-P-05-4025
Device, it can determine gas flow by the size driving electric current.When electric current is zero, gas flow is zero, therefore, and this watt
This controller can be as gas breaker.Refer to Fig. 3, for example, multisection type gas controller can be syllogic gas control
Device processed, it is made up of two control valves 30a in parallel, 30b and two groups of Y shape gas splitters, wherein, control valve 30a
Flow be the half of control valve 30b.For example, the flow of control valve 30a is 1/2 unit, and the flow of control valve 30b is 1/
4 units.According to this structure, by control valve 30a, the opening or closing of 30b, syllogic gas controller can produce fully closed, 1/4,
Three kinds of gas flows such as 1/2 and 3/4 unit, that is respectively corresponding fully closed and little, in, big three kinds of stove fires.May be appreciated
It is that adjustment control valve 30a, the control signal of 30b can be produced by temperature sensor 20.
According to said structure, the sensing signal and that thermopile sensor 21 can be exported by signal processor 22 presets temperature
Angle value is made comparisons, and can produce suitable control signal when sensing signal exceedes preset temperature value to adjust gas flow,
I.e. adjust stove fire.Such as, during boilers from drying burning, will close, to avoid causing danger by stove fire；Or when the material in pan seethes with excitement
Will turn down by stove fire, to save gas or to avoid soup to overflow.
Refer to Fig. 2, thermopile sensor 21 comprises an a pyroelectricity pile sensing element 21a and thermistor 21b.Temperature-sensitive
Resistance 21b can compensate for pyroelectricity pile sensing element 21a, to obtain accurate sensing result.In an embodiment, TEMP
Device 20 further includes lens 23, and it is arranged at a receiving terminal of pyroelectricity pile sensing element 21a.Lens 23 have high focal length
(being greater than 5mm), receives the ultrared sensing view angle theta that pan radiated limiting thermopile sensor 21, so may be used
Thermopile sensor 21 is avoided to sense the stove fire of inner ring combustion chamber 11a.In other words, the position that arranges of thermopile sensor 21 can be relatively

The infrared ray radiated.In an embodiment, jacket 24 can be made by low sintering ceramic material.Preferably, adiabatic
The inwall of set 24 comprises multiple salient point 241, and multiple salient point 241 contacts with thermopile sensor 21 with fixing thermopile sensor
21.It is understood that fix thermopile sensor 21 with the salient point 241 of jacket 24 inwall can reduce thermopile sensor
21 with the contact area of jacket 24 inwall, to reduce the thermal energy conduction outside jacket 24 to thermopile sensor 21.Additionally,
Air between thermopile sensor 21 and jacket 24 inwall also has insulation effect.
In an embodiment, temperature sensor 20 comprises a protection cap 25, and it is arranged at the form of jacket 24.Can manage
Solving, protection cap 25 needs to pass through infrared ray.Protection cap 25 can prevent dirty lens 23 or the pyroelectricity pile sensing element 21a of making dirty
And affect the degree of accuracy of sensing.Dirty protection cap 25 needs to wipe out at any time, and therefore protection cap 25 needs preferably wearability.
For example, the material of protection cap 25 can be sapphire.
In an embodiment, signal processor 22 comprises dc amplifier 221, bias resistance 222, signal multiplexing
Device 223, one analog-to-digital converter 224 and a microcontroller 225.Bias resistance 222 is in order to measure thermistor 21b's
Resistance value, to extrapolate the environment temperature of pyroelectricity pile sensing element 21a, and then calculates the actual temperature of pan.Direct current amplifies
Device 221 is in order to amplify the sensing signal that pyroelectricity pile sensing element 21a is exported.Signal multiplexer 223 is used for switching from temperature-sensitive
The sensing signal that the signal of resistance 21b or dc amplifier 221 are amplified, and be fed to analog-to-digital converter 224 and change
For being calculated by microcontroller 225 after data signal and judging.For example, when pan temperature is more than a preset temperature value
Time, microcontroller 225 i.e. exports one and controls signal to gas controller 30, to adjust gas flow, and then adjusts stove fire size.
In an embodiment, the output port of microcontroller 225 can be digital, such as I2C, UART, analog voltage formula or logic
IO exports.
It is understood that numeral I/O port can be two-way, that is the exportable temperature information of microcontroller 225
Or control signal to external electronic, also can accept control signal or setup parameter that external electronic inputs from far-end,
To adjust the parameter of gas oven.For example, user can close stove fire or design temperature condition, such as cooking temperature from far-end
Or the critical-temperature of dry combustion method, or pan kind or radiation coefficient, the radiation coefficient adjusting pan for microcontroller 225 comes
Calculate temperature information.
