The utility model is transformed for the water dispenser of shortcoming to office of water dispenser in prior art, microwave induced principle is utilized to make in drinking-water function automatic detection office with or without personnel activity, judge the personnel's whether just of short duration process in room simultaneously, automatically heating function is controlled again, water dispenser is heated when monitoring personnel, do not have not heat when personnel, not only avoid water dispenser and repeatedly heat for a long time, and can electric energy be saved.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of be applicable to office can monitor-type water dispenser, comprise single stabilization delay circuit, body induction circuit, capacity voltage dropping circuit.
Wherein said capacity voltage dropping circuit includes the first electric capacity C1, second electric capacity C2, first resistance R1, voltage-stabiliser tube DW and diode D1, the first described electric capacity C1 and the first resistance R1 forms parallel circuit, the first end of this parallel circuit connects heater switch K, the heater switch other end connects power supply 220V by fuse F1, second end connects power supply 220V after connecting voltage-stabiliser tube DW, second end also connects diode D1, power supply 220V is connected after second electric capacity C2, the two ends of the second electric capacity C2 and the output of capacity voltage dropping circuit, the output of capacity voltage dropping circuit connects single stabilization delay circuit, body induction circuit, for it provides stable llV DC voltage.
Described body induction circuit is microwave induction controller IC1(TX982).
Described single stabilization delay circuit includes 555 time base circuit IC2(NE555), connect power supply 220V after the trigger end (pin 2,6) of 555 time base circuits connects the second resistance R2, after also connecting the 3rd electric capacity C3, connect power supply 220V; The trigger end of 555 time base circuits is also connected with the output (pin 2) of microwave induction controller IC1; The output (pin 3) of 555 time base circuits connects relay coil J, and described relay coil J two ends are connected with diode D2.The normally opened contact K1 of relay is connected in heating control circuit.Described heating control circuit by being incubated indicator lamp LED1, burner on light LED2, temperature control contact WK, heater RL connect, and are prior art.
Microwave induction controller IC1(TX982), include microprocessor, utilize microwave Doppler effect, electric microfield is set up in certain space, the meeting reflection echo when having people or mobiles to enter electric field, after electronic circuit mixing, detect atomic weak frequency-shift signaling, this signal after Intelligent treatment, exportable control signal.The effective monitoring radius of TX982 1 ~ 7 meter.Here repacking is convenient not adopt the reason of pyroelectric sensor mainly to consider, and pyroelectric sensor is responsive especially to thermal source, easy malfunction.As long as microwave induction controller is arranged on after water dispenser plastic front board and just can detects, water dispenser outward appearance can not be destroyed.The output of TX982 adopts open collector to export, and when microwave circuit has detected that people is movable in monitoring range, inner triode ON 10 seconds, falls the charge discharging resisting on electric capacity C3.555 time base circuit IC2(NE555), when the 2nd pin is lower than 1/3 supply voltage, 3rd pin exports high level, relay J adhesive, then normally opened contact Kl connection heater RL heats, the delay time of R2 and C3 composition is 3 minutes, delay time sets shorter, if personnel are of short duration process, drinking machine heating will stop after 3 minutes automatically, if have people in room always, TX982 will repeatedly trigger monostable circuit work in delay time, water dispenser will continuous heating until reach design temperature.
