Embodiment
As shown in Figure 1: the present invention includes the MCU control module, the input end of MCU control module connects the discharge water testing circuit and the power supply of water dispenser; The output terminal of MCU control module connects relay; The contact of relay is connected in the supply line of water dispenser heater block or heating and refrigeration part.
The testing circuit that discharges water comprises two switches that link with the water dispenser water drain valve, detects the user and whether uses water dispenser, and the state of switch will change when water dispenser discharges water the user, and this change informs that MCU control module user is using water dispenser; Relay is used for conducting or disconnects the power supply of water dispenser heater block or semiconductor refrigerating parts, the output contact of relay is connected to the temperature controller input end of water dispenser, if water dispenser adopts the electronic cooling mode, might not use the temperature controller of similar heater block, use thermistor instead, at this moment, the output contact of relay connects the ac input end that is used for providing galvanic Switching Power Supply to the electronic cooling parts.
As shown in Figure 2, the MCU control module comprises single-chip microcomputer, microcontroller power supply circuit, water dispenser switching on and shutting down action is passed to the optocoupler circuit of single-chip microcomputer, and the control signal of single-chip microcomputer output passed to relay, control the control relay circuit of its folding.Two pins of the Kwarm of MCU and Kcool are right respectively+and the 5V power supply connects a pull-up resistor, meets working power ground GND by switch S 1, S2 respectively simultaneously, just differentiates the action that whether discharges water with level.S1 detects hot water valve, and S2 detects cold valves, and for the water dispenser that has only heating function, MCU only detects S1, and S2 only works on the water dispenser of band refrigeration.
The microcontroller power supply circuit comprises decompression capacitor C1, forms diode D1, D2, D3, D4, the resistance R 3 that is used for current-limiting protection, the resistance R 4 that is used to discharge, stabilivolt D6 and the filter capacitor C2 of rectifier bridge heap.During the positive half cycle of electric main, electric current is through current-limiting protection resistance R 3, decompression capacitor C1, commutation diode D1, relay K 1 line bag, stabilivolt D6, commutation diode D4, form the loop,, provide the working power of single-chip microcomputer being attempted by the power filtering capacitor C2 charging on the D6; During the negative positive half cycle of electric main, electric current is through commutation diode D2, relay K 1 line bag, stabilivolt D6, commutation diode D3, decompression capacitor C1, current-limiting protection resistance R 3, form the loop,, provide the working power of single-chip microcomputer being attempted by the power filtering capacitor C2 charging on the D6;
Optocoupler circuit comprises a phototriode and a light emitting diode.When 1,2 pin of photoelectrical coupler U2, when just an effluent of light emitting diode is crossed certain electric current, phototriode will change conducting state along with the variation of light-emitting diode luminance.If the brightness of light emitting diode is enough strong, when just the electric current in the light emitting diode is enough big, phototriode will be in state of saturation, finish the conversion of output level; When light-emitting diode luminance is big inadequately, phototriode will be in linear working state.Utilize this characteristic of photoelectrical coupler, the on-off state that the ON/OFF pin of MCU control module can the perception water dispenser is convenient to the user and is allowed water dispenser withdraw from idle state by switching on and shutting down, the work of force revert water dispenser.
As shown in Figure 1, open water dispenser, electricity-saving controller at first enters the self study cycle, MCU control section guard relay K1 conducting, and the work of nonintervention temperature controller, water dispenser is pressed traditional mode work under the control of temperature controller.In this process, the MCU control module is by the switch S 1, the S2 that detect and water drain valve links, and perception user's use habit knows when let slip water, when does not discharge water; Self study by certain hour, operate in the software in the MCU control section, by the artificial intelligence fuzzy algorithm, automatically the identification user uses the custom of water dispenser, count water dispenser fixing section standby time every day, again rational switching on and shutting down cycle of intelligent planning water dispenser, compress standby time of water dispenser to greatest extent.According to the result of self study, the decision of MCU control section is set at idle state with water dispenser in one day a certain set time section.At this moment, high level of RELAYout pin output of MCU control section, inject base current for triode Q2 by resistance R 12, triode Q2 conducting thereupon, cause the conducting of triode Q1 again, so relay K 1 adhesive line bag both end voltage is reduced to the saturation voltage drop of triode Q1 rapidly, the normally opened contact of relay K 1 becomes disconnection by conducting, cut off power supply to temperature controller, though the temperature controller adhesive of water dispenser at this moment, because the disconnection of relay K 1, refrigeration or heater block can't obtain voltage, cisco unity malfunction is so water dispenser enters idle state.
When standby time, section was about to finish, the RELAYout pin output of MCU control section is by high step-down, triode Q2 ends immediately, and triode Q1 also ends simultaneously, through flow through the once more adhesive line bag of relay K 1 of the electric current of diode D1, D2, D3, D4 rectification, this electric current makes the normally opened contact adhesive conducting of relay K 1, voltage adds to the water dispenser temperature controller again, and water dispenser recovers refrigeration and heating function, so, this idle period ends, and water dispenser enters normal operating conditions.When thinking that etc. next MCU control section water dispenser need enter idle period once more, repeat said process again.
If water dispenser is being opened, the user is not for a long time by the water drain valve water intaking, for energy savings, also in order to prevent thousand boiling water, controller directly by the RELAYout pin closed relay K1 of MCU, forces water dispenser to enter idle state when detecting the water dispenser certain hour and be not used.
If the MCU control module has been set water dispenser and has been entered idle state, just in case user's temporary needs is drunk hot water, the user only need turn-off the water dispenser power switch one time, open the water dispenser power switch again, because relay K 1 has disconnected, photoelectrical coupler can detect level conversion one time, and this signal changed pass to MCU, after the MCU control section determines current switching on and shutting down action, pilot relay K1 adhesive immediately, finish the current idle state of water dispenser, enter duty, the idle period of this time period is cancelled at this point.Perhaps, the user also can be by pushing the water drain valve water intaking, and controller detects user's water demand, and the MCU control module is pilot relay K1 adhesive equally immediately, finishes the current idle state of water dispenser, enters duty.
After water dispenser uses this electricity-saving controller, saved the power consumption that water dispenser is in idle state greatly.Through rough calculation, generally speaking, 365 days accumulative total of a water dispenser is economized on electricity about 180 degree.
The present invention possesses following characteristics:
1, link in switch S 1, the S2 of cold and hot water drain valve by detection, directly when the perception user uses water dispenser.2, by 24 hours detection, tentatively finish self study to user's custom, implement economize on electricity control.3, by the self study of longer time, judge use habit weekly, more reasonably plan the water dispenser work period.4, a relay K 1 is arranged in the electricity-saving controller, relay K 1 is subjected to the control of MCU control module on the electricity-saving controller, the switching on and shutting down cycle that software in the MCU control section is good according to planning, pilot relay K1 switches on and off, guarantee that it is to keep operate as normal that water dispenser is in the period commonly used, when the expection water dispenser will enter idle state, relay K 1 kept disconnecting, cut off the power supply of water dispenser, do not allow its non-productive work.5, the switching on and shutting down signal is judged: when electricity-saving controller is set at idle state with water dispenser, if the user needs the situation of hot water, only need the power supply of a water dispenser of switch, electricity-saving controller will be judged user's current switching on and shutting down, finish the current idle state of water dispenser, be the water dispenser power supply immediately.6, the MCU control section is taked low power dissipation design, and annual power consumption is no more than 5 degree.When 7, each user pushes the water drain valve water intaking and the switch of water drain valve interlock user's the action that discharges water can be informed single-chip microcomputer immediately.
