Device of the present utility model is formed (see figure 1) by several parts: one is an infrared temperature measuring probe 4, launches ultrared strong and weak the variation according to the height of object being measured temperature, produces the variation of voltage signal.It two is a main control board 9.It is used for control heater 21 three for heating intensity control executive component 20, and heater 21 can be combustion gas or fuel oil stove and accessory (see figure 3), and the heating intensity control executive component 20 of this moment can be magnetic valve, is used to control fuel gas or fluid flow.(see figure 4) when heater 21 is electric heater, heating intensity control executive component 20 can be relay, is used to control the electric heater delivery, and heater 21 also can be the heater of following variety of way, as electromagnetic oven, infrared heater etc.Kitchen range 2 also can be micro-wave oven, baking box, fry in shallow oil dish, chafing dish etc.For adopting solid-fuelled kitchen range such as timber, charcoal, coal, also available a kind of double boiler body, and, reach the effect of controlling upper strata pot temperature with a kind of automatically controlled servo control mechanism control double boiler spacing of two layers up and down.This moment, control executive component 20 of the present utility model can be controlled the kettle temperature of this double boiler.Main control board 9 carries out computing with the various signals of telecommunication of infrared temperature probe 4 input and relatively amplifies, and sets the given voltage of band switch 10 with temperature and compare.When being higher than set-point, output voltage makes it fuel flow rate diminished or add thermoelectric (al) power to diminish to heating intensity control executive component 20, reaches the effect of control cooking temp.The electrical source of power 11 of the control circuit of kitchen range operation can provide safe low-voltage by the transformer isolation step-down rectifier, or is provided by 6 volts or 12 volts of batteries.
This infrared measurement of temperature control 4 can place kitchen range to be heated top, below or the side of utensil.
Infrared temperature probe is mainly by infrared temperature sensor 12, and light pipe 14 and thermistor 13 etc. are formed (see figure 2).
Temperature automatically controlled no oil smoke energy-saving stove is equipped with regularly acoustical generator 26, and when material temperature in the heating container rose to the set gear relevant temperature of temperature regulating switch 10, main control board 9 sent voltage instruction to regularly acoustical generator 26 pronunciations.
The specific embodiment
Embodiment 1 (see figure 3): present embodiment adopts fuel gas or flammable liquid to do fuel, flame takes place with corresponding kitchen range 22, after pot 1 is placed on the kitchen range 2, open fuel general import ignition switch 8 earlier, fuel gas or atomizing, flammable liquid after the gasification enters this device through switch 8, and then enter kitchen range 22 through magnetic valve 6 and choke valve 7 simultaneously, and ignited simultaneously, switch 8 is threaded to maximum flame location, Fast Heating pot on the height of anger, the magnetic valve 6 of this moment is in the normally open position, require to regulate temperature according to different culinary arts then and set band switch 10, a given suitable temperature value, when the infrared temperature sensors 4 in this moment thermometric hand 3 detected in the container temperature of charge and rise to the temperature adjustment wave band and open the corresponding temperature of half 10 set gears, main control board 9 output voltages were closed magnetic valve 6, and flame is reduced, provide flammule required fuel by choke valve 7, safeguard that the temperature in the pot 1 no longer rises.When adding materials in the pot 1, kettle temperature descends, and master control borad 9 turn-offs output voltage rapidly, and magnetic valve 6 power interruption recoverings often leave, and it is maximum that flame recovers.When being heated plate 9 output voltages, close magnetic valve 6, flame is reduced.Optoelectronic switch 5 is to be made by infrared-emitting diode.
Temperature adjustment band switch 10 can select be set 6-8 kind steady temperature gear according to cooking method (boil, fry in shallow oil, explode, fry), and scope is 98 ℃-230 ℃, makes the edible oil in the pot can pyrolysis gasification simultaneously, thereby reaches the effect of no oil smoke.
Infrared temperature probe 4 (see figure 2)s are installed on the temperature detection hand 3, infrared temperature sensor 12 wherein can be rapidly accurate object temperature in the induction kettle, produce voltage signal, export comparison circuit 17 amounts of locating of main control board 9 to.And measure infrared thermometries probe 4 self variations in temperature by temperature probe 13, resistance value to the temperature-compensation circuit of master control borad 9 of output non electrical quantity linear change is handled getting rid of the interference of infrared thermometry probe 4 self variations in temperature, thereby can accurately record object temperature in the container.
An optoelectronic switch 5 is installed in the kitchen range 2 simultaneously, whether pot 1 is arranged on the induced cooking utensils 2, and signal is delivered to master control borad 9, to regulate the heating power size, not only saved the energy this moment, improved security again by its control heater 21.
Embodiment 2 (see figure 4)s: present embodiment adopts electric furnace 23 as heater, after pot 1 is placed on the kitchen range 2, connect power supply 24, electric current enters electric furnace 23 through relay 25 (normally closed road), Fast Heating pot 1, require to regulate temperature according to different culinary arts then and set band switch 10, a given suitable temperature value, when the infrared thermometries probe 4 in this moment thermometric hand 3 detects in the container temperature of charge and rises to the corresponding temperature of temperature adjustment band switch 10 set gears, the husband is met in master control borad 9 outputs makes 25 one-tenth open circuits of relay, close current stops heating, and the temperature in the pot 1 no longer rises.When adding materials in the pot 1, kettle temperature descends, and master control borad 9 turn-offs output voltage rapidly, and relay 25 recovers normally closed recovery heating.When being heated pot 1 when leaving kitchen range, signal is sent in optoelectronic switch 5 inductions, by master control borad 9 output voltages, power supply is cut off stopped heating.
