A control system for a full-function water heater

Abstract

The invention discloses a control system for a full-function water heater, which includes a hot water heat preservation water tank with a temperature transmitter and a water level transmitter, constant temperature return water equipment, constant pressure water supply equipment, water replenishment system, air energy heating equipment, heat recovery Heating equipment, solar heating equipment and real-time connection with the temperature transmitter and water level transmitter in the hot water insulation tank to control the hot water insulation tank to achieve constant temperature return operation, constant pressure water supply operation, water replenishment operation and air energy heating The main controller of the operation function has three communication interfaces on the main controller. The first communication interface communicates with the touch screen of the system man-machine interface. The second communication interface is connected with the expansion module and the smart meter through the selection switch. The switch is a selection switch capable of selecting the communication between the expansion module and the main controller alone, or the communication between the smart meter and the main controller alone, or the communication between the expansion module and the smart meter and the main controller at the same time. The invention has high operation reliability and reduces cost.

Description

technical field [0001] The invention relates to the technical field of hot water control, in particular to a control system for a full-function water heater. Background technique [0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc. The advantages of water heaters are high thermal efficiency, fast heating speed, stable temperature regulation, continuous use by multiple people, and a group of fixed consumers. Hot water can be supplied at any time in the kitchen in winter, which is convenient; the water temperature is constant, and the purchase cost is cheap. For ordinary families, it is enough to use an 8-liter machine, so it is deeply loved by people. With ...

AI Technical Summary

Problems solved by technology

For ordinary families, it is enough to use an 8-liter machine, so it is deeply loved by people. With the continuous development of science and technology, there are more and more functional requirements for water heaters. With the increase of functions, the control system of hot water is also increasing. It is relatively complex and difficult to control. Since each device in the current water heater control system works independently, the information during its work cannot be shared or coordinated, so it is easy to cause relatively high costs and relatively high operating reliability. Poor, so needs improvement
