Described microwave induction controller adopts TX982 microwave induction controller.
Described single stabilization delay circuit adopts 555 time base circuits.
The microwave induction controller of the intelligent type energy saving water dispenser that the present embodiment provides and single stabilization delay circuit, as follows in operation principle:
Power pack is formed typical capacity voltage dropping circuit by Cl, C2, Rl, DW, D, provides stable llV DC voltage to TX982 and 555 time base circuit.TX982 is microwave induction controller, include microprocessor and 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, atomic weak frequency-shift signaling is detected after electronic circuit is mixed, this signal after Intelligent treatment, exportable control signal.The effective monitoring radius of TX982 1～7 meter.Mainly consider that repacking is convenient here without the reason adopting pyroelectric sensor, and pyroelectric sensor is especially sensitive to thermal source, it is easy to malfunction.As long as microwave induction controller is arranged on after water dispenser plastic front board and just can be detected, water dispenser outward appearance will not be destroyed.The outfan of TX982 adopts open collector output, and when microwave circuit has detected people's activity in monitoring range, internal triode ON 10 seconds, falls the charge discharging resisting on C3.555 circuit composition single stabilization delay circuits, when the 2nd foot is lower than 1/3 supply voltage, the 3rd foot output high level, relay adhesive, Kl connects heater and is heated, the delay time of R2 and C3 composition is 3 minutes, and delay time is set to comparatively short, if personnel are of short duration process, drinking machine heating will be automatically stopped after 3 minutes, if there is people in room always, TX982 repeatedly will trigger in delay time monostable circuit work, water dispenser will continuous heating until reaching design temperature.
If to improve energy-saving effect further, it is necessary to some the little transformations of heating tank toothed oak to water dispenser, the Insulation of most of water dispensers is very simple, and heating tank is surrounded by the foam plastics only with two panels preforming, so heat radiation is quickly.Preferably carrying out foam-in-place filling with polyurethane material (the general producer manufacturing solar water heater has) in heating tank surrounding, so process can make between thermal insulating material section and heating tank very close to each other, reduces air flowing and can be greatly improved heat insulation effect.
What finally illustrate is, above example is only in order to illustrate technical scheme and unrestricted, although by referring to the preferred embodiments of the present invention, invention has been described, but it will be understood by those within the art that, in the form and details it can be made various change, without departing from the spirit and scope that the present invention limits.
