Description

An intelligent frequency conversion energy-saving water dispenser

technical field

The utility model relates to the technical field of drinking water equipment products, in particular to an intelligent drinking water equipment.

Background technique

With the improvement of living standards and the development of science and technology, people have higher requirements for the safety and sanitation of drinking water. In this case, drinking water equipment has been developed rapidly. Traditional drinking water equipment has functions such as boiling (heating), disinfection, sterilization, refrigeration, and heat preservation, so it has won the favor of consumers. At present, most of all water dispensers on the market use high-quality iron-chromium-aluminum and nickel-chromium electrothermal alloy wires as raw materials for heating. The rated voltage is divided into AC220V and AC380V, and the power ranges from 500W to 12000W. The disadvantage is that the structure of the existing water dispenser is set to be heated at full power when the temperature is lower than the set temperature, so that the water molecules are always in accelerated motion, generating a large amount of water vapor, and the water vapor is discharged into the waste water through the pressure relief valve. When the boiling water is not used for a long time, the temperature will slowly drop, and when it is lower than the set temperature, it will be heated to boiling with full power, and repeated heating in this way will generate thousands of boiling water and waste water and electricity.

Utility model content

The technical problem to be solved by the utility model is to provide an intelligent frequency conversion energy-saving water dispenser which can select the heating power according to the water temperature.

In order to solve the above technical problems, the utility model adopts the following technical solutions: an intelligent frequency conversion energy-saving water dispenser, including a body, a water tank, a heating device, a water outlet switch, a control circuit board, a display screen and an operation panel, and the water tank and the control circuit board are located at Inside the fuselage, the display and operation panel are located on the surface of the fuselage, the heating device and the control circuit board are connected to the power adapter, and the display and operation panel are connected to the control circuit board; there is a temperature control sensor in the water tank, and the temperature control sensor is connected to the control circuit board , it is characterized in that: the heating device includes at least two groups, each group of heating devices is independent of each other, each includes a heating tube and a matching heating relay, and the heating relay is connected to the control circuit board; all the heating tubes are connected together at one end The neutral wire of the power supply is connected to the live wire independently at the other end.

Further, there are 2-7 heating tubes, and each heating tube is matched with an independent heating relay.

Further, an anti-boil-dry water level probe is provided in the water tank, and the anti-boil-dry water level probe is connected to the heating tank water level control mechanism on the control circuit board.

The chip in the control circuit board adopts the chip of model number 2003A, PT7C4302, R8C2K, M54123 or LM7805.

This intelligent frequency conversion water dispenser completely changes the previous heating method. Firstly, the existing heater power is segmented and decomposed, and the intelligent microcomputer chip is used to follow the change of heating temperature to instruct the heater to continuously reduce the heating power. When the difference between the water temperature and the set temperature is large, the chip controls the heater to heat at full power. When the water temperature rises, the chip starts to unload the power of the heater gradually, effectively controlling the uniform movement of water molecules, greatly reducing the evaporation of water vapor, and then Reduce heat loss and achieve energy-saving effect; when boiling water is not used for a long time, the water temperature will slowly drop to the set temperature point, at this time, the chip will instruct the heater to perform micro-electrical insulation at low power according to the frequency of boiling water, and No high-power heater is used to prevent the generation of thousands of boiling water. In this way, the generation of water vapor can be reduced to achieve the effect of energy saving and water saving; at the same time, the heater can change the heating mode to prolong the life of the heating tube.
