Description

Water dispenser control device with health role

Technical field

The invention belongs to electronic technology and power-saving technique field, is about a kind of water dispenser control device with health role.

Background technology

Water dispenser use now is very universal, but after common water dispenser commonly used turned on the power switch, the pure water in the water tank can be heated for a long time repeatedly, and the such pure water of long-term drinking not only is unfavorable for health but also quite wastes electric energy.Use in the pure water process in reality, the most of the time, we only needed the water dispenser short time that hot water is provided.There is the defective that is heated repeatedly in order to remedy and to overcome existing common water dispenser control circuit pure water, is necessary to develop a kind of water dispenser control device that economize on electricity effect and health-care effect are arranged.

Summary of the invention

Goal of the invention and beneficial effect: exist pure water in the water tank to be heated repeatedly for a long time and waste electric energy and the pure water drunk through heating repeatedly is unfavorable for problems such as health in order to overcome existing water dispenser, the present invention has realized the purpose of drinking machine electricity-saving, health care by addressing the above problem at the several components and parts of the inner increase of common water dispenser.Technology of the present invention both can be used as the upgrading servicing unit of common water dispenser and had developed separately, also capable of being combinedly carried out supporting exploitation to water dispenser inside.

Technical scheme: water dispenser control device with health role, form by power switch SW, fuse BX, temperature controller WK, electric heating tube RL, heating indicating circuit, insulation indicating circuit and self-locking holding circuit, it is characterized in that: comprise civil power dropping resistor, full bridge rectifier, direct current filter circuit, DC relay in the self-locking holding circuit;

The self-locking holding circuit is characterised in that: step-down current-limiting resistance R3 one end is by temperature controller WK, the power switch SW of mutual serial connection, the live wire end L that fuse BX connects civil power, input one end of another termination full bridge rectifier alternating current of resistance R 3, the zero line side N of another input termination civil power of the alternating current of full bridge rectifier, the two ends that the direct current positive pole of full bridge rectifier and cathode output end are succeeded electrical equipment J coil two ends and electrochemical capacitor C1 respectively; The normally opened contact J-1 of relay J is attempted by the two ends of power switch SW.

Circuit is formed: typical water dispenser control circuit is made up of power switch SW, fuse BX, temperature controller WK, electric heating tube RL, heating indicating circuit, insulation indicating circuit; Water dispenser control device with health role is on the basis that the original circuit structure of water dispenser remains unchanged, increase the several electrons components and parts newly and formed the self-locking holding circuit, it comprises civil power reduction voltage circuit, full bridge rectifier, dc source filter circuit, action execution relay.

The self-locking holding circuit is by the civil power dropping resistor, full bridge rectifier, the direct current filter circuit, action is carried out relay and is formed, the annexation of components and parts is in the circuit: the temperature controller WK of step-down current-limiting resistance R3 one end by being connected in series mutually, power switch SW, fuse BX meets the live wire end L of civil power, resistance R 3 another termination full bridge rectifiers (being made up of 4 silicon rectifier diode D3～D6) alternating current is imported an end, the zero line side N of another input termination civil power of full bridge rectifier alternating current, full bridge rectifier direct current both positive and negative polarity output is succeeded the two ends of coil and the electrochemical capacitor C1 of electrical equipment J respectively, and the normally opened contact J-1 of self-locking holding circuit repeat circuit J is attempted by the two ends of water dispenser power switch SW.

Operation principle: there is a ship shape power switch SW back side of water dispenser or side, and it has the energising heating and disconnects two positions.Civil power is that electric heating tube RL two ends power up by fuse BX, temperature controller WK after power switch SW closure.Simultaneously civil power obtains the 12V dc source after by resistance R 3 step-downs, full bridge rectifier, electrochemical capacitor C1 filtering, and DC relay J adhesive makes the normally opened contact J-1 closure of relay J.At this moment, if power switch SW is disconnected, electric heating tube still is in heated condition, when pure water was heated to temperature controller WK design temperature in water tank, temperature controller WK promptly disconnected, and the relay J dead electricity disconnects normally opened contact J-1, circuit withdraws from self-locking state, no longer heats later on.
