Embodiment
Below in conjunction with the drawings and specific embodiments, set forth the present invention further.These embodiments are interpreted as only being not used in for illustration of the present invention limiting the scope of the invention.After the content of having read the present invention's record, those skilled in the art can make various changes or modifications the present invention, and these equivalence changes and amendment fall into the scope of the claims in the present invention equally.
In the utility model following examples, though electrical device is for electric cooker, but technical solutions of the utility model according to following examples, can be applied to electric kitchen tools or living room electrical appliance by those skilled in the art, 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, Microwave emission receiver module 2, microwave generator 21, antenna 22, connects wire 3, the controller processing unit 4 being with MCU and rice cooker body 5.Connection between culinary art panel 1 and rice cooker body 5 and matching relationship are according to the conventional means of this area.Microwave emission receiver module 2 is arranged in electric cooker, then the controller processing unit 4 of Microwave emission receiver module 2 and band MCU is electrically connected just constitutes a kind of inductive switch (as shown in Figure 2) by being connected wire 3.
After electric cooker energising, as the distance≤2m of human body proximity culinary art panel 1, the change of wave-shape amplitude on the antenna 22 causing Microwave emission receiver module 2, other function of electric cooker can be controlled further: when human body proximity is not to when having a rice cooker body 5 after the change of inductive waveform amplitude on antenna 22 being detected by being with the MCU Program on the controller processing unit 4 of MCU, user interface (display screen, button indicating lamp) can be caused to light (welcome lamp), send the phenomenon of prompt tone or other function action.
After the distance leaving rice cooker body 5 when human body is greater than 2m, user interface (display screen, function button pilot lamp) automatic distinguishing, plays energy-saving effect.
How illustrate human body proximity rice cooker body 5 below in conjunction with accompanying drawing causes user interface (display screen, button indicating lamp) to light.
When the utility model previous embodiment is based on physical activity, the echo of its reflection is interferenceed with the former microwave field of microwave generator (or frequency) and causes antenna wave-shape amplitude to change, by being with the voltage variety on the MCU detection antenna 22 on the controller processing unit 4 of MCU.When detecting that the variable quantity of voltage on emitting antenna 22 reaches certain amplitude, namely judge have people to control user interface close to also exporting.
As shown in Figure 4, the maximal value of the static data display induced voltage of unmanned movement is 3.16V, and minimum value is 2.78V.
As shown in Figure 5, the maximal value of the image data display induced voltage of human body movement within the scope of 1 meter is 3.66V, and minimum value is 1.56V.
As shown in Figure 6, the maximal value of the image data display induced voltage of human body movement within the scope of 2 meters is 3.47V, and minimum value is 1.88V.
When not having human body to move in effective range, waveform is without obvious amplitude (as shown in Figure 4); When human body moves within the scope of 1 meter and 2 meters, amplitude of wave form obviously strengthens, the nearlyer amplitude of distance larger (as seen in figs. 5-6).
