Automatic water circulation device for electric boiler

Abstract

The invention discloses an automatic water circulation device for an electric boiler. The automatic water circulation device for the electric boiler comprises a housing, and a plurality of sets of heating devices are disposed in the housing. Each heating device comprises a water storing tank disposed in the housing and a return water tank communicating with the water storing tank. The return water tanks communicate with return water pipelines. Water inlets used for water feeding are formed in the water storing tanks. The return water tanks communicate with heating water tanks through short return water pipes, and power devices are disposed inside the heating water tanks. The heating water tanks communicate with water outlet pipes, heating mechanisms are disposed on the water outlet pipes, and the water outlet pipes communicate with water outlet pipelines. A controller is disposed in the housing, connected with temperature sensors disposed on the water outlet pipelines or the return water pipelines and connected with the power devices and the heating devices. The automatic water circulation device for the electric boiler is reasonable in design, low in maintenance rate, capable of saving energy, environmentally friendly, efficient and suitable for being widely popularized and serves as an ideal water supply system.

Description

technical field [0001] The invention belongs to the field of water circulation devices, and in particular relates to an automatic water circulation device for an electric boiler. Background technique [0002] The daily electric blanket is provided with evenly distributed resistance wires inside the blanket, and then generates heat by heating the resistance wires. However, its hazards are also obvious. A large number of resistance wires in the electric blanket produce high electromagnetic radiation, which seriously affects human health. In addition, the electric blanket is easy to dry out, has hidden dangers of electric leakage, and can easily cause fires when it is powered on for a long time. [0003] With the development of water heating, water heating blankets and water heating panels have entered people's lives, but the existing water heating blankets and water heating panels use centrifugal pumps to deliver water, that is, the impeller is driven by the pump shaft to rota...

AI Technical Summary

Problems solved by technology

Since the impeller is always in a rotating state, the seal at the impeller is easily worn and damaged, and the leaked water will soak the cushions and clothes, causing great inconvenience to use

Especially when the return pipe or the water inlet pipe is bent and blocked, the impeller is always working, resulting in an increase in the power of the impeller and causing the centrifugal pump to burn out
