Embodiment
Below in conjunction with the drawings and specific embodiments, further set forth the present invention.These embodiment are interpreted as being only not used in and limiting the scope of the invention for the present invention is described.After having read the content of the present invention's record, those skilled in the art can make various changes or modifications the present invention, and these equivalences change and amendment falls into the scope of the claims in the present invention equally.
In the utility model following examples, though electrical device is taking electric cooker as example, but those skilled in the art can, according to following examples, be applied to electric kitchen tools or living room electrical appliance by technical solutions of the utility model, such as electric pressure pot, electromagnetic oven and black brilliant stove (electricity pottery stove) etc.
As shown in Figure 1, the electric cooker with human body proximity induction installation that the utility model one preferred embodiment provides, comprises culinary art panel 1, sensor wire 2, connects wire 3, controller 4 and rice cooker body 5 with MCU.Connection between culinary art panel 1 and rice cooker body 5 and matching relationship are according to the conventional means of this area.Sensor wire 2 is arranged in to culinary art panel 1 inner peripheral or its arbitrary region, then sensor wire 2 and controller 4 with MCU are electrically connected and have just formed a kind of inductive switch (as shown in Figure 2) by being connected wire 3.
After electric cooker energising, in the time that human body proximity is cooked the distance≤2m of panel 1, cause the variation of induced voltage on sensor wire 2, other function that can further control electric cooker after the variation of induced voltage on sensor wire 2 detected by the MCU Program on the controller 4 with MCU: when human body proximity is not when touching culinary art panel 1, can cause that user interface (display screen, button indicating lamp) lights (welcome lamp), send the phenomenon of prompt tone or other function action; Hold electric conductor when human body and approach culinary art when panel 1, also can occur causing that user interface (display screen, button indicating lamp) lights, send the phenomenon of prompt tone or other function action.
When human body leave culinary art panel 1 distance be greater than 2m after, user interface (display screen, function button pilot lamp) automatic distinguishing, plays energy-saving effect.
How to cause that below in conjunction with specific experiment explanation human body proximity culinary art panel 1 user interface (display screen, button indicating lamp) lights.
The utility model previous embodiment is based on radar Doppler principle, sends extremely lower powered electromagnetic wave and accepts reflection echo by the MCU on the controller 4 with MCU with sensor wire 2.If detect, the reflection frequency of induction region changes, and gathering waveform can change, and the MCU Program on the controller 4 with MCU detects the variation of induced voltage on sensor wire 2, reaches certain value and judges have people to approach and export to control and welcome lamp light.
As shown in Figure 3, unmanned mobile static data shows that the maximal value of induced voltage is 3.16V, and minimum value is 2.78V.
As shown in Figure 4, human body mobile image data within the scope of 1 meter shows that the maximal value of induced voltage is 3.66V, and minimum value is 1.56V.
