Description
Technical field
The utility model relates to water heater control technology field, particularly relates to a kind of water heater with human body sensing device.
Background technology
Water heater is a kind of very conventional home appliance, and along with the progress of technology, a lot of water heater all adopts touch-screen to realize manipulation.But under night non-switch on condition or when indoor light is darker, people cannot find respective operations button to set, operate comparatively inconvenience.Meanwhile, under open state, water heater LED display is lighted for a long time, is in wake-up states always, very easily causes damage, to such an extent as to causes whole water heater control device to use.In addition, the water heater of common belt switch switch power supply deixis, its power LED lamp Chang Liang always, LED light work is long for service time, and brightness and life-span also reduce gradually, very easily occurs damaging.
Summary of the invention
For problems of the prior art, the purpose of this utility model is the water heater providing a kind of display screen and key indicator lamp automatically to wake up.
For reaching above object, the utility model adopts following technical scheme.
With a water heater for human body sensing device, comprising: Master control chip, it is characterized in that, Master control chip is connected with pyroelectric infrared sensor, display screen and key indicator lamp; Described Master control chip receives the signal of pyroelectric infrared sensor, and controls waking up and closedown of display screen and key indicator lamp according to the signal received.
Further illustrating as such scheme, the model of described Master control chip is MB95F263KPF, and the 18 pin of Master control chip connects the signal output part of pyroelectric infrared sensor; Master control chip the 14,13,12 pins are connected with display screen by driving chip.
Further illustrating as such scheme, the model of described driving chip is TM1638.
Further illustrating as such scheme, is also connected with signal amplification circuit between pyroelectric infrared sensor and Master control chip.
Further illustrating as such scheme, described pyroelectric infrared sensor comprises Fresnel optical filter and pyroelectricity element, and described pyroelectricity element is two electric capacity of reversal connection, and infrared ray is gathered on pyroelectricity element after being strengthened by Fresnel optical filter.
Further illustrating as such scheme, pyroelectric infrared sensor is also provided with photo resistance.
Compared with prior art, the utility model has following beneficial effect:
One, by being connected with pyroelectric infrared sensor on Master control chip, display screen and key indicator lamp, avoiding lighting display screen and key indicator lamp always, improving the use working life of display screen, more energy-conservation.
Two, adopt pyroelectric infrared sensor to realize induction angle and distance Based Intelligent Control to regulate and sensor itself is low in energy consumption lower.
Three, by increasing photo resistance at pyroelectric infrared sensor, can suppress to trigger display screen daytime and LED lights always, more energy-conservation.
Accompanying drawing explanation
Figure 1 shows that the water heater control principle drawing of the band human body sensing device that the utility model provides;
Figure 2 shows that control chip circuit connection diagram;
Figure 3 shows that and drive display circuit figure;
Figure 4 shows that human inductor structural representation.
Detailed description of the invention
For setting forth essence of the present utility model further, by reference to the accompanying drawings detailed description of the invention of the present utility model is described as follows.
As shown in Figure 1, a kind of water heater with human body sensing device, comprising: Master control chip 1, pyroelectric infrared sensor 2, display screen 3 and key indicator lamp 4; Described Master control chip 1 receives the signal of pyroelectric infrared sensor 2, and controls waking up and closedown of display screen 3 and key indicator lamp 4 according to the signal that receives.Described display screen 3 and key indicator lamp 4 all adopt LED as light source.
During real work, at energising holding state, when people enters the induction range of setting, receive human body signal by pyroelectric infrared sensor 2, then export high level, automatically wake water heater display screen 3 and key indicator lamp 4 up.Also the key position that water heater is corresponding can be found when night, light was darker to carry out operating and setting, play night vision operating function.At energising holding state, when people is away from induction range, now regulate the demand of water heater without operation, then pyroelectric infrared sensor 2 output low level, Master control chip 1 receives signal, automatically closes water heater display screen 3 and key indicator lamp 4.
As shown in Figure 2 and Figure 3, the model of described Master control chip 1 is MB95F263KPF, and the 18 pin of Master control chip 1 connects the signal output part of pyroelectric infrared sensor 2; Master control chip 1 the 14,13,12 pins are connected with display screen 3 by driving chip.In the present embodiment, the model of described driving chip is TM1638.Especially, for ensureing that signal can accurately identify, between pyroelectric infrared sensor 2 and Master control chip, also signal amplification circuit is connected with.
As shown in Figure 4, shown pyroelectric infrared sensor 2 comprises Fresnel optical filter 21 and pyroelectricity element 22, and described pyroelectricity element is two electric capacity of reversal connection.Operation principle is: the infrared ray of about 10 μm of human-body emitting is by gathering on pyroelectricity element 22 after Fresnel optical filter 21 enhancing, when pyroelectricity element 22 does not detect the infrared signal that human body radiation goes out, the positive and negative electric charge that polarization is contrary at electric capacity two ends, electricity is equal, so, positive and negative charge is cancelled out each other, no current in loop, pyroelectric infrared sensor no-output.When human body is still in surveyed area, the infrared ray light energy be irradiated on two electric capacity is equal, and reaches balance, and the photoelectric current that polarity is contrary, energy is equal is cancelled out each other in the loop, and pyroelectric infrared sensor does not still have signal to export.When human body moves in surveyed area, the infrared energy be irradiated on two electric capacity is unequal, and photoelectric current can not be cancelled out each other in the loop, and pyroelectric infrared sensor has signal to export.Utilize the pyroelectric infrared sensor of this technology, be applied on water heater, effectively overcome the shortcoming of prior art, provide a kind of human body sensing device technology, practicality is stronger.
Further, for avoiding water heater to receive the signal of pyroelectric infrared sensor 2 by day and lighting display screen 3 and indicator lamp 4, pyroelectric infrared sensor 2 is also provided with photo resistance, triggers display screen to suppress daytime and LED lights always, more energy-conservation.
Above detailed description of the invention has been described in detail essence of the present utility model, but can not limit protection domain of the present utility model with this.Apparently, under the enlightenment of the utility model essence, the art those of ordinary skill also can carry out many improvement and modification, it should be noted that these improve and modify and all drops within claims of the present utility model.
