Abstract

The utility model relates to a water dispenser control device with a healthcare effect, which consists of a power switch SW, a fuse BX, a temperature controller WK, an electric heating tube RL, a heating indication circuit, a heat insulation indication circuit and a self-locking retaining circuit. The water dispenser control device is characterized in that the self-locking retaining circuit comprises an electric supply voltage reduction resistor, a full bridge rectifying circuit, a direct-current electric filtering circuit and a direct-current relay. In order to resolve problems that purified water in a water storage tank of an existing water dispenser is repeatedly heated for a long time, electric energy is wasted, health of users is affected after the users drink the purified water heated repeatedly, and the like, several elements are additionally arranged in a common water dispenser, and purposes of healthcare and electricity economization of the water dispenser are realized. The water dispenser control device in the technology not only can be independently produced as an upgrading auxiliary device of the common water dispenser, but also can be directly combined into the water dispenser so as to be used with the water dispenser.

Description

Water dispenser control device with health role

Technical field

The utility model 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 by long repeated heating, 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.Exist by the defective of repeated heating in order to remedy and to overcome existing common water dispenser control circuit pure water, be necessary to develop a kind of water dispenser control device that economize on electricity effect and health-care effect are arranged.

The utility model content

Goal of the invention and beneficial effect: exist pure water in the water tank to be wasted electric energy and the pure water drunk through repeated heating is unfavorable for problems such as health by repeated heating for a long time in order to overcome existing water dispenser; The utility model has been realized the purpose of drinking machine electricity-saving, health care through addressing the above problem at the several components and parts of the inner increase of common water dispenser.The technology of the utility model 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 meets the live wire end L of civil power through temperature controller WK, power switch SW, the fuse BX of mutual serial connection; 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 carried out relay by civil power dropping resistor, full bridge rectifier, direct current filter circuit, action and is formed; The annexation of components and parts is in the circuit: step-down current-limiting resistance R3 one end meets the live wire end L of civil power through temperature controller WK, power switch SW, the fuse BX of mutual serial connection; 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 breaks off two positions.Civil power is that electric heating tube RL two ends power up through fuse BX, temperature controller WK after power switch SW closure.Simultaneously civil power obtains the 12V dc source after through resistance R 3 step-downs, full bridge rectifier, electrochemical capacitor C1 filtering, and DC relay J adhesive makes the normally opened contact J-1 of relay J closed.At this moment, if power switch SW is broken off, 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 broke off, and the relay J dead electricity is broken off normally opened contact J-1; Circuit withdraws from self-locking state, no longer heats later on.

Description of drawings

Accompanying drawing 1 is the circuit working schematic diagram of water dispenser control device with health role.

The specific embodiment

Accompanying drawing 1 and description of drawings to specifications below are example with water dispenser control device with health role to be further described the correlation technique of the utility model.

The selection of components and parts and technical parameter thereof
