Light energy water heater

Abstract

The invention relates to the field of energy conservation and environmental friendliness, and discloses a light energy water heater. In the light energy water heater provided by the invention, because an optical heat collection device and a heat-insulating water tank are independently arranged and the manufacturing cost is reduced, so that the optical heat collection device and the heat-insulating water tank can be separately arranged to make the installation and maintenance more convenient; the heat-insulating water tank is arranged indoors, and the heat collection device is arranged on an outdoor wall, so that the distance from the heat-insulating water tank to a hot water outlet is shortened and the water consumption is saved; a used control device has the functions of automatic circulation and automatic control, so that the feed-water circulation and heating can be automatically controlled; and the water is circularly heated through a light energy heat collection metal tube, so that scales are not formed and the service life of the product is prolonged. In addition, safety voltage of not more than 36V is adopted for heating when sunshine cannot meet the demand, so the using safety of a user is guaranteed and the safety of the product is improved.

Description

technical field [0001] The invention relates to the field of energy saving and environmental protection, in particular to a light energy water heater. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the use of water heaters is becoming more and more popular; and solar water heaters are more widely used due to their energy-saving and environmental protection features. [0003] At present, common solar water heaters are roughly divided into two types: one is a water heater in which a solar collector vacuum glass tube is directly inserted into an insulated water tank; the other is a heat pipe pressure-bearing water heater. However, the disadvantages of the prior art solar water heaters are: the heat collecting device and the heat-preserving water tank are integrally installed on the roof, which is very inconvenient for installation and maintenance, and the heat-preserving water tank is arranged on th...

Problems solved by technology

However, the disadvantages of the prior art solar water heaters are: the heat collecting device and the heat-preserving water tank are integrally installed on the roof, which is very inconvenient for installation and maintenance, and the heat-preserving water tank is arranged on the light heat collecting device, requiring strong support Rack, the production cost is quite high. In fine weather, the water temperature rises very high, and you can bathe normally; but when the water temperature is high, it is easy to scale, so after one or two uses, the thermal efficiency will decrease and need to be descaled
