Description

The water dispenser circuit

Technical field

The utility model belongs to household electrical appliance technical field, particularly a kind of water dispenser circuit.

Technical background

Water dispenser is indispensable electric equipment products in our daily life.After the household drinker opening power of the prior art,, all are in heating always at daytime or night, are incubated the recurrent state heat again, be incubated no matter be no matter in the room nobody is arranged.When particularly nobody drinks when pure water, pure water in the water tank is heated for a long time repeatedly, this at first is unfavorable for health, because water can be made the mineral matter in the water body run off by heating repeatedly, often drinks such water and can not replenish the mineral matter that is comprised in the common water body.If prolonged and repeated boiled, then the sodium ion in the water can produce natrium nitrosum, is unfavorable for health.Simultaneously, because repeated boiling also can consume a large amount of electric energy, be unfavorable for energy-conserving and environment-protective.

The utility model content

The purpose of this utility model provides a kind of energy-conservation, water dispenser circuit of helping health.

The purpose of this utility model adopts following technical scheme to realize: this water dispenser circuit is by attaching plug XP, power switch SA1, heating temperature control device ST1, electrothermal tube EH, anti-dry heating temperature controller ST2, diode VD1, VD2, insulation indicator lamp LED1, burner on light LED2, resistance R 1, R2 forms, be characterized in also having an electrothermal tube control circuit in the circuit, described control circuit is by power circuit, delay circuit, microwave induced control circuit and bidirectional triode thyristor are formed, described power circuit is by capacitor C 1, C2, resistance R 3, Zener diode DW, and diode VD3 forms, the input of power circuit joins with attaching plug XP and power switch SA1, its output connects delay circuit and microwave induced control circuit, described delay circuit is by time base circuit IC1 and peripheral resistance R 4 thereof, capacitor C 3 constitutes, resistance R 4, capacitor C 3 just is being serially connected in power circuit output, between negative pole, resistance R 4, the node of capacitor C 3 connects the input pin 2 of time base circuit IC1; Described microwave induced control circuit adopts microwave sensor IC2, and the output pin 3 of microwave sensor IC2 connects the node of resistance R 4 in the delay circuit, capacitor C 3; Described bidirectional triode thyristor VS1 is connected on attaching plug XP and anti-dryouting between the temperature controller ST2, and the control utmost point of bidirectional triode thyristor VS1 connects the output pin 3 of time base circuit IC1.

Water dispenser circuit working principle provided by the utility model is as follows: this water dispenser circuit has increased the electrothermal tube control circuit of being made up of power circuit, delay circuit, microwave induced control circuit and bidirectional triode thyristor on the basis of common water dispenser circuit, power circuit wherein is by capacitor C 1, C2, resistance R 3, Zener diode DW and commutation diode VD3 form typical capacity voltage dropping circuit, half-wave rectifying circuit, filter circuit of pressure-stabilizing.Provide galvanic current to press to time base circuit and microwave induced control circuit.The microwave induced control circuit that is made of microwave sensor IC2 utilizes the microwave Doppler effect, constantly at certain spatial emission electromagnetic wave, will reflection echo when people or mobiles enter electromagnetic field, after its internal electron circuit mixing, detect atomic weak frequency-shift signaling, this signal after treatment, the output control signal, about 1～7 meter of its effective monitoring radius.When detecting by the people, microwave induced control circuit in monitoring range, exports control signal to the single stabilization delay circuit of forming by 555 time base circuit IC1 and peripheral resistance R 4 thereof, capacitor C 3 when movable, charge discharging resisting on the capacitor C 3 is fallen, make 555 time base circuit IC1 the 2nd pin (being the voltage on the capacitor C 3) that constitutes delay circuit keep below 1/3 supply voltage, time base circuit IC1 the 3rd pin output high level, bidirectional triode thyristor VS1 conducting, electrothermal tube heats.If personnel are of short duration process, electrothermal tube is heated to delay time then will be stopped automatically.If never have the people in the room, electrothermal tube just keeps outage, stops heated condition.Because the single stabilization delay circuit that 555 time base circuit IC1 and peripheral resistance R 4 thereof, capacitor C 3 are formed, its delay time is decided by the circuit that charges and discharge that resistance R 4 of joining with 555 time base circuit IC1 the 2nd pin and capacitor C 3 are composed in series.When and when the 2nd pin (being the voltage on the capacitor C 3) when being higher than 1/3 supply voltage, the 3rd pin output low level, bidirectional triode thyristor VS1 closes, electrothermal tube stops heating.If the people is arranged in the room always, microwave induced control circuit will repeatedly discharge the electric charge on the capacitor C 3 in delay time, make 555 circuit the 2nd pin voltage can't be elevated to 1/3 supply voltage, so the 3rd pin remains high level output, the water dispenser power supply is connected in bidirectional triode thyristor VS1 conducting.Power switch SA1, heating temperature control device ST1, electrothermal tube EH, anti-dry heating temperature controller ST2 constitute electric power loop.Electrothermal tube EH heating heats up the water in the water tank, when water temperature is raised to 97 ℃, heating temperature control device ST1 auto power off, burner on light LED2 extinguishes, electrothermal tube stops heating and changes insulation over to, meanwhile, diode VD1, insulation indicator lamp LED1, resistance R 1, electrothermal tube EH and anti-dry heating temperature controller ST2 constitute the loop, and LED1 is luminous for the insulation indicator lamp.When drinking-water or cooling naturally, when the water tank water temperature dropped to 87 ℃, heating temperature control device ST1 connected power supply automatically, and electrothermal tube EH generates heat once more, and water temperature is remained between 89 ℃～97 ℃.Water dispenser will keep the normal operating conditions that heats, be incubated.

According to the reality test, the water dispenser water of heating water tank first approximately needs 7 minutes, is incubated 28 minutes afterwards, heats 2 minutes again, if there is not hot water to pour out, after this just constantly repeats insulation, heats this process, and cycle period is about 30 minutes.If the people is arranged 8 hours by the room, nobody calculated in 16 hours, adopted water dispenser circuit provided by the utility model, every water dispenser 16 * 4/60 * 0.55=0.6 degree (kilowatt hour) that can economize on electricity every day, 1 year 365 * 0.6=219 degree that can economize on electricity.
