Embodiment
As shown in Figure 1, 2: the drinking machine electricity-saving control technology of band self-learning function, comprise the MCU control section that is used to judge the water dispenser duty, connect the heating testing circuit of the on off operating mode that is used to detect the temperature controller contact at the input end of MCU control section; Output terminal at the MCU control section connects the relay that is used for conducting or disconnects the power supply of water dispenser heater block, and the contact of described relay is connected to the temperature controller input end of water dispenser.
Wherein the MCU control section comprises: single-chip microcomputer, indication water dispenser be in idle state light emitting diode D9, be used to accept the switch S 1 that the user forces to heat instruction.
The heating testing circuit comprises a current transformer T1, is some discrete devices of current transformer T1 signal shaping.
Power circuit comprises diode D1, D2, D3, D4, the resistance R 1 that is used for current-limiting protection, the resistance R 2 that is used to discharge, stabilivolt D7, the power filtering capacitor C4 that implements decompression capacitor C1, forms the rectifier bridge heap, and it is responsible for providing operating voltage to the MCU control section.
Relay K 1 is subjected to the control of MCU control section, and according to the software control rule, conducting or disconnection are to reach the purpose of reasonable control water dispenser heating.
If selected energy saver mode during the water dispenser start, as Fig. 1, 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, when water dispenser is in keeping warm mode, temperature controller disconnects, have only very little electric current to flow through among the current transformer T1, belong to a milliampere level, deficiency is so that the secondary generation induced voltage of current transformer T1, and the MCU control section is just thought and the not work of water dispenser heater block is in keeping warm mode; In case temperature controller is connected, the work of heater block causes flowing through among the current transformer T1 very big electric current, above 2 amperes, induced voltage of the secondary generation of current transformer T1, after diode D5, resistance R 9, capacitor C 3 shapings, produce the signal that the MCU control section can be discerned, the MCU control section thinks that in view of the above water dispenser enters heated condition, and resistance R 8 and diode D8 are the devices that is used to protect the MCU control section; Heating finishes the back temperature controller and disconnects once more, the blackout of current transformer T1, and the MCU control section detects water dispenser once more and enters keeping warm mode.
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, counts water dispenser fixing section standby time every day, again the rational switching on and shutting down cycle of intelligent planning water dispenser, compress the standby time of water dispenser to greatest extent, thereby reach the purpose of energy savings, existing tangible economic benefits more have great social effect.In the modern society of energy prices hurricane, energy savings means the environment of preserving our planet, and also is equivalent to the regeneration of the energy.
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 32 pin output of MCU control section, inject base current for triode Q2 by resistance R 7, 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, has cut off the power supply to temperature controller, even the temperature controller adhesive of water dispenser at this moment, because the disconnection of relay K 1, heater block can't obtain voltage, can not implement heating, so, water dispenser enters idle state, no longer possesses heating efficiency.Simultaneously, the MCU control section through resistance R 5, makes light emitting diode D9 light by high level of 26 pin output, informs the user, and water dispenser has entered power down mode, and during this period, the water in the water dispenser can not be heated again.
When standby time, section was about to finish, the 32 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 heating function, so, this idle period ends, and water dispenser enters normal operating conditions.Simultaneously, the MCU control section changes the output of 26 pin into low, and light emitting diode is gone out by bright change, and the expression water dispenser withdraws from power down mode.When thinking that etc. next MCU control section water dispenser need enter idle period once more, only need high level of output on 32 pin.
If the MCU control section 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 press a pressure on the water dispenser panel and add hot key S1, after the MCU control section determines current button, finish current idle state immediately, enter duty, implement heating, the idle period of this time period is cancelled at this point.
For the water dispenser that has refrigerating function concurrently, the refrigerating part line construction and the heating part of its increase are basic identical, have just increased a temperature controller in addition, are used to control refrigeration part.The self study process is judged with the same with the hot type reason with idle state.
Fig. 3, the 4th, a kind of version that control section is external, Fig. 1, Fig. 2 than internally-arranged type have reduced button among Fig. 3, increased photoelectrical coupler Q3, Q4 among Fig. 4.Because the externally positioned type electricity-saving controller is independent of water dispenser, can't be as the built-in economize on electricity water dispenser of this patent electricity-saving controller, between lay-up period by forcing the water dispenser heating by the hot key that adds on the panel, external electricity-saving controller must be able to detect the switch motion of water dispenser and the disconnection and the closure state of temperature controller, therefore needs to increase photoelectrical coupler Q3, Q4 and finishes this function.
Concrete principle is as follows: in order to protect light emitting diode, heating on the water dispenser and insulation pilot lamp are generally all gone here and there respectively a diode, is used to prevent the light emitting diode reverse breakdown.Like this, the electric current that flows through on light emitting diode has just had direction, only could pass through electric current along the direction of diode.The circuit of different manufacturers water dispenser may there are differences, and that is to say, there are two kinds of possibilities in the installation direction of diode.Therefore, the externally positioned type electricity-saving controller is considered the versatility of different product, has adopted the scheme of two light lotus roots, and no matter how diode is installed, and can implement to detect.Photoelectric coupled device is made of a phototriode and a light emitting diode.1,2 pin as photoelectrical coupler Q3 or Q4, when just light emitting diode one effluent is crossed certain electric current, phototriode will be along with the variation of light-emitting diode luminance, change conducting state, 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, 24 pin of MCU control section can the perception different situations under the state of water dispenser, this electricity-saving controller just can be judged water dispenser and be in start or off-mode, during start, temperature controller is in and disconnects or closure state.The externally positioned type electricity-saving controller is seen a switch motion of water dispenser customer requirements as and is forced heating, and the hot key that adds that is equivalent on the economize on electricity water dispenser panel that electricity-saving controller has been installed has been pressed once; Under the water dispenser open state, the externally positioned type electricity-saving controller becomes the once heating request that closure is regarded water dispenser as to temperature controller by disconnection, at this moment, the MCU control section pilot relay K1 conducting of electricity-saving controller, make water dispenser finish heating, because photoelectrical coupler Q3, Q4 is attempted by the two ends, contact of relay K 1, photoelectrical coupler Q3, Q4 quits work during this period, the heating process of water dispenser is monitored by current transformer T1, when heating finished the temperature controller disconnection, current transformer T1 informed that the heating of MCU control section finishes, in order to save more electric energy, this moment, the MCU control section passed through 32 pin, disconnected the contact of relay K 1; Electricity-saving controller becomes temperature controller to disconnect by closure regards that once heating finishes as.
The measuring ability that photoelectrical coupler Q3, Q4 summation current transformer T1 have been arranged, the externally positioned type electricity-saving controller just can successfully realize self-learning function and reset switching on and shutting down cycle of water dispenser, and software and hardware principle of work fundamental sum Fig. 1 of this respect, internally-arranged type drinking machine electricity-saving controller shown in Figure 2 are identical.
After water dispenser uses this electricity-saving controller, saved the power consumption that water dispenser is in idle state greatly.Rough calculation, generally speaking, 365 days accumulative total of a water dispenser is economized on electricity about 150 degree.In today of energy prices Gao Qi, economize on electricity just equals to economize on coal, fuel-economizing, solar term, also equals pollution emission reduction, also is equivalent to the regeneration of the energy simultaneously.
Existing timing type electricity-saving controller on the market, patent of the present invention has better adaptability and dirigibility, need not to set clock, avoided because the timing confusion that clocking error and temporary interruption cause, save human intervention, easy and simple to handle, have more hommization.
The present invention possesses following characteristics: 1, under certain room temperature, the temperature that water dispenser insulation can back warp is crossed the water of heating is reduced to and reheated the needed natural cooling time of temperature spot is constant, if this cooling interval obviously shortens, just can think that the user had used the hot water of some, this is as the criterion of identification user use habit.If 2 water dispensers are in considerable time, each cooling interval and heating substantially constant perdurability can think that generally nobody uses water dispenser in this time period, and this is in the criterion of idle state as water dispenser.3, the temperature controller that carries in the water dispenser has temperature controlled function, and when the water temperature in the insulation can is lower than a certain design temperature, temperature controller will be connected the power supply of heater block, reheats for the water in the insulation can.Heater block can equivalence be a resistor, when having electric current to flow through, and resistor heats up, the heat of generation is absorbed by water, and water temperature rises thereupon.4, a relay K 1 is arranged in the electricity-saving controller, relay K 1 is subjected to the control of the MCU control section 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 to implement heating during water dispenser is in normal operating conditions, during the expection water dispenser was in idle state, relay K 1 kept disconnecting, the heating request of refusal water dispenser.5, the identification of heating request: have a custom-designed circuit to be used to differentiate the interior temperature controller of water dispenser in the external electricity-saving controller and be in conducting or off-state, temperature controller is switched to conducting from disconnection be defined as once heating request, detect heating process with a current transformer T1 simultaneously.The water dispenser of built-in this electricity-saving controller has been save above-mentioned circuit, only uses heating that a current transformer T1 judges water dispenser whether, has electric current to represent the temperature controller conducting, heater block work, otherwise, illustrate that then water dispenser is in keeping warm mode.6, after the external electricity-saving controller is received the heating request of water dispenser, if water dispenser is in the non-idle state cycle, the relay K 1 on the electricity-saving controller will be powered to water dispenser, allow water dispenser finish the heating of water; During the idle state, electricity-saving controller is ignored to the heating request of water dispenser.For the built-in water dispenser of this electricity-saving controller, between lay-up period, relay K 1 is in off-state, finishes engage relay K1 behind the idle period, allows the heater block heating work.7, the power consumption of electricity-saving controller itself is extremely small, and 1 year is no more than 3 and spends.8, water dispenser is set at idle state when electricity-saving controller, if the user needs the situation of hot water, electricity-saving controller can't be finished the power supply to water dispenser.For the external electricity-saving controller, at this moment, the user only needs the power supply of a water dispenser of switch, and electricity-saving controller will be judged user's current switching on and shutting down, finishes the current idle state of water dispenser, is the water dispenser power supply immediately.For the built-in water dispenser of electricity-saving controller, at this moment can force water dispenser to withdraw from idle state, immediately heating by by a switch on fuselage.
The present invention judges the temporal regularity that water dispenser is in idle state by monitoring the heating cycle of water dispenser in real time, determines according to this rational opening and closing cycle of water dispenser to reach the effect of saves energy.This scheme is used simple and reliable, with low cost.
