Description

A kind of intelligent energy-saving drinking water machine circuit

Technical field

The present invention relates to field of circuit control, especially relate to a kind of intelligent energy-saving drinking water machine circuit.

Background technology

In daily life, water dispenser has become electrical equipment essential in family life. Water dispenser is generally divided into Warm water drinking machine, semi-conductor straight cooling type cold and hot water drinking machine, compression formula refrigerating drinker three kinds, and its principle of work of water dispenser dissimilar in three is different. Existing water dispenser all adopts its heating of automatic control circui or refrigeration, by being programmed by control chip, sets heat-up time, and the data gathering of water temperature is controlled by sensor. Function of drinking water like this keeps having hot water to quote for a long time, it is not necessary to Artificial Control.

But existing above-mentioned water dispenser exists an obvious problem, after the trip switch of water dispenser is opened, the Controlling System of water dispenser will work under acquiescence mode of operation always. Carry out heating work according to the data that temperature sensor returns, immediately when no one quotes water, when the water temp in water dispenser reduces, also by temperature sensor feedback data to controller, controller control can be caused to heat. Going round and beginning again, the water in water dispenser will be heated always, until there being people to close water dispenser so that water dispenser stops work completely. Such operating mode not only makes water dispenser waste a large amount of electric energy, and simultaneously because tap water is ceaselessly heated, the water of heating for multiple times makes the mineral substance in water be decomposed, and finally can cause the generation of incrustation scale, be unfavorable for HUMAN HEALTH.

Summary of the invention

It is an object of the invention on the basis of existing pilot circuit, it is proposed to a kind of can the circuit of adaptive control type of heating so that pilot circuit auto sleep and automatically activating in people's situation having when no one uses, meets energy-conservation object.

The present invention adopts following technical scheme for achieving the above object:

A kind of intelligent energy-saving drinking water machine circuit, this circuit is input between output from power supply to be connected with power switch, well heater, temperature control contact switch; It is characterized in that accessing between described power switch and power output end capacity voltage dropping circuit, microwave induction controller and timing circuit; Described capacity voltage dropping circuit provides to microwave induction controller and timing circuit stablizes volts DS.

In technique scheme, the output terminal of described microwave induction controller is that open collector exports.

In technique scheme, described microwave induction controller comprises microwave Doppler effect generator.

In technique scheme, the radius of the electric microfield that described microwave Doppler effect generator produces is 1��7 meter.

In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: the circuit of the present invention has just made tiny change on traditional circuit, increase a small amount of device, therefore do not need how to revise in the improvement to existing circuit and just can realize object, microwave induction controller can be directly installed in the inner casing of water dispenser, can not affect the outward appearance of water dispenser.

Accompanying drawing explanation

Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:

Fig. 1 is the schematic circuit diagram of the present invention.

Embodiment

Heater switch pressed by traditional water dispenser, and power supply is that " insulation " pilot lamp LED1 provides power supply, does energising instruction. One road forms heating circuit, and electric heating pipe RL electrified regulation is heated up; Another road is that " heating " pilot lamp LED2 provides voltage to do heating instruction. When the water in tank hot in water dispenser is heated to the temperature of setting, temperature controller contact switch WK disconnects, and cuts off heating, and heating instruction loop power supply, " heating " pilot lamp LED2 extinguishes, and electric heating pipe RL stops heating. When water temperature drop is to design temperature, temperature controller contact switch WK switches on power loop, and electric heating pipe RL generates heat again, makes water temperature remain between 85-95 DEG C so again and again. Warm and hot drinking device circuit adopts dual protection element, when water dispenser overtemperature or be short-circuited fault time, overtemperature fuse cutout is automatically molten or temperature controller with manual reset disconnects heating circuit power supply automatically, plays a protective role. Overtemperature fuse cutout is disposable thermal protective element, can not reset, and waits the overtemperature fuse cutout more renewed by former model specification after fixing a breakdown, then presses the reset button of temperature controller with manual reset with hand, and the closing of contact just can be reworked.

As shown in Figure 1, it is the schematic circuit diagram of the present invention; The basis of traditional circuit increases capacity voltage dropping circuit, the typical capacitance step-down circuit of this electricity routing capacitance C1, electric capacity C2, resistance R1, diode DW, diode D composition. The function of this typical capacitance step-down circuit is exactly by the 220V voltage of alternating current step-down of input and is converted to the volts DS of 11V; Microwave induction controller in this volts DS supply circuit and timing circuit.

In the present invention, microwave induction controller selects TX982, and this inductor block includes microprocessor, microwave Doppler generator, utilizes microwave Doppler generator to produce an electric microfield in certain space, and this electric microfield is stable output electric field. When having moving object or people to enter within the scope of electric field, electric field is at the surface generation reflection echo of moving object or people, detect out after electronic circuit mixing and faint shifting signal frequently, after the microprocessor processes of secondary signal in microwave induction controller, export a control signal; This control signal adopts open collector to export.

When microwave induction controller has detected people within the scope of electric microfield during activity, the output terminal triode ON of TX982 10 seconds, falls the charge discharging resisting on electric capacity C3. Timing circuit adopts 555 timers, is single time delay circuit, and when the 2nd pin of timer is lower than 1/3 voltage of supply, the 3rd pin exports high level, relay J adhesive, and K1 connects well heater RL and heats.

The time delay time that resistance R2 and C3 forms is set as 3 minutes, and the setting of time delay time is shorter; If in electric microfield, the process that personnel's knowledge is of short duration or stop, water dispenser will stop heating automatically after heating 3 minutes under the control of microwave induction controller, if there is people in the scope of electric microfield always, TX982 will repeatedly trigger monostable circuit working within the time delay time, and water dispenser will continue to heat the temperature of through setting.The application of this circuit makes the type of heating of water dispenser make present triggering heating into by former circulation heating, avoids always working of water dispenser, save energy, can ensure better water quality simultaneously. Water dispenser is had more standby intelligent.
