Solar water heater with indoor heat insulation box

Abstract

The invention discloses a solar water heater with an indoor heat insulation box. The solar water heater comprises a solar water heater body and a cold water inlet pipe and is characterized by furthercomprising the indoor heat insulation box, a three-way valve, an electromagnetic valve, an integrated controller and a water mixing valve. A water inlet and outlet pipe of the solar water heater bodyis connected with a water inlet pipe of the indoor heat insulation box through the three-way valve, the water inlet and outlet pipe of the solar water heater body is connected with a cold water inletpipe through the three-way valve, the electromagnetic valve is arranged on the cold water inlet pipe and electrically connected with the integrated controller, the integrated controller is arranged inthe indoor hear insulation box, one water inlet of the water mixing valve is connected with a water outlet pipe of the indoor heat insulation box, and the other water inlet of the water mixing valveis connected with the cold water inlet pipe. The solar water heater has the beneficial effects that the problem that heat loss of the solar water heater is large is solved, the utilization rate of thesolar water heater is maximized, the problem that cold water is accumulated in a water outlet pipeline to affect use of hot water in the solar energy industry for a long time is solved, the system structure is simple, hot water supply is stable, hot water can be supplied within 24 h all day, and outlet water temperature is constant.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization. Background technique [0002] Solar water heaters are installed outdoors, resulting in high heat loss, and the energy cannot be stored for a long time. In addition, there is usually a lot of cold water in the outdoor pipes. In actual use, it takes a long time to wait until the cold water is drained. Use, not only wastes water but also affects the comfort of use, has become a difficult point to be solved urgently for solar water heaters. If traditional water storage electric water heaters are used, however, in today's shortage of resources and electric energy and environmental problems. It is an important issue to make products more energy-efficient, economical and environmentally friendly. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and provides a solar water heater with an indoor heat preservation box which has a better heat pre...

[0002] Solar water heaters are installed outdoors, resulting in high heat loss, and the energy cannot be stored for a long time. In addition, there is usually a lot of cold water in the outdoor pipes. In actual use, it takes a long time to wait until the cold water is drained before it can be normal. Use, which wastes water and affects the comfort of use, has become a difficult point to be solved urgently for solar water heaters. If traditional water storage electric water heaters are used, however, in today's resource and power shortage and environmental problems that are becoming more and more prominent Making products more energy-efficient, economical and environmentally friendly is an important topic
