The specific embodiment
Further specify the technical solution of the utility model below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, Fig. 1 is the structured flowchart of the auto-induction apparatus preferred embodiment of the utility model micro-wave oven.The auto-induction apparatus of this micro-wave oven comprises:
Signal deteching circuit 10 is used for obtaining the distance between infrared emitter and the micro-wave oven when detecting infrared signal, and itself and the threshold value of presetting is compared;
Because the people knows from experience the generation infrared ray, therefore when the human body proximity micro-wave oven, the infrared signal that signal deteching circuit 10 can human body sends, and when detecting infrared signal, calculate the distance between human body and the micro-wave oven.When judging that human body is near micro-wave oven, then control circuit 20 control micro-wave ovens start corresponding operation, for example open display screen and show or open illuminating lamp etc.The automatic induction method of the utility model micro-wave oven is by detecting infrared signal, judge the distance between infrared emitter and the micro-wave oven, and operate accordingly according to judged result control micro-wave oven, thereby so that micro-wave oven responds user's action no longer passively, but sensed in advance, and make corresponding operation, be very easy to user's use.
Further, with reference to Fig. 2, above-mentioned signal deteching circuit 10 comprises:
Further, above-mentioned control instruction comprises the control illumination lamp ignition or closes.Particularly, when the distance between human body and the micro-wave oven is less than or equal to default threshold value, show close micro-wave oven of human body, then control illumination lamp ignition, make things convenient for user's operation; When the distance between human body and the micro-wave oven during greater than default threshold value, show human body away from micro-wave oven, then control illuminating lamp and extinguish.When micro-wave oven is in light not during overabundant operating environment, sensed in advance, and when the human body approach micro-wave oven, light illuminating lamp, thus made things convenient for user's operation; Extinguish illuminating lamp at human body during away from micro-wave oven, both realized intelligence operation, saved again lighting energy.
Further, above-mentioned control instruction comprise micro-wave oven display screen demonstration or close.Particularly, when the distance between human body and the micro-wave oven is less than or equal to default threshold value, show human body near micro-wave oven, the display screen of then controlling micro-wave oven shows, makes things convenient for user's operation; When the distance between human body and the micro-wave oven during greater than default threshold value, show human body away from micro-wave oven, the display screen of then controlling micro-wave oven does not show.By sensed in advance, the control display screen shows when the human body approach micro-wave oven, and during away from micro-wave oven, the control display screen does not show, has not only realized intellectualized operation, but also has saved the energy at human body.
With reference to Fig. 3, Fig. 3 is the electrical block diagram of the auto-induction apparatus of the utility model micro-wave oven.Wherein, infrared receiving circuit 11 comprises PIR(Passive InfraRed, passive infrared) sensor and accessory circuit thereof, this infrared receiving circuit 11 is mainly used in passive reception infrared signal, and is converted into voltage signal.The function of counting circuit 12 and comparison circuit 13 is then realized by integrated chip U2.Integrated chip U2 to the signal that infrared receiving circuit 11 receives amplify, after filtering etc. processes, calculate the distance that obtains between infrared emitter and the micro-wave oven, and itself and default threshold value compared, if the distance between infrared emitter and the micro-wave oven is then exported high level signal to control circuit 20 greater than default threshold value; If the distance between infrared emitter and the micro-wave oven is less than or equal to default threshold value, then the output low level signal is to control circuit 20.The function of this control circuit 20 is then realized by integrated chip U1.The signal that it produces according to signal deteching circuit, and produce corresponding control instruction, with the work of control micro-wave oven.Lighting circuit for example, its lighting circuit can comprise LED(LED1, LED2, LED3, the LED4 that drives triode (Q1, Q2, Q3, Q4) and drive).Wherein, the emitter stage that drive triode Q1, drive triode Q2, drive triode Q3, drives triode Q4 all is connected with+5V power supply, colelctor electrode is corresponding to be connected with the positive pole of LED1, LED2, LED3, LED4, and base stage is corresponding to be connected with the output of control circuit 20.The control signal that output by control circuit 20 produces, control drives the base stage of triode, thereby drives the triode conducting, and the voltage of+5V power supply flows to connected LED by the driving triode of conducting, thereby lights this LED.
Above-mentioned auto-induction apparatus can independently arrange, and also can be arranged on the micro-wave oven.For example, the utility model also provides a kind of micro-wave oven, and it comprises auto-induction apparatus, and the structure of this auto-induction apparatus and function can with reference to noted earlier, just repeat no more at this.
The above only is preferred embodiment of the present utility model; be not so limit its claim; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
