Solar water heater with indoor thermal insulation box

Abstract

The invention relates to a solar water heater with an indoor thermal insulation box, which comprises a solar water heater and a cold water inlet tube. The invention is characterized in that the solar water heater also comprises an indoor thermal insulation box, a three-way valve, an electromagnetic valve, an integrated controller and a water mixing valve, wherein a water inlet tube and a water outlet tube of the solar water heater are communicated with a water inlet tube of the indoor thermal insulation box through the three-way valve, a water inlet tube and a water outlet tube of the solar water heater are communicated with the cold water inlet tube through the three-way valve, the electromagnetic valve is arranged on the cold water inlet tube and is electrically connected with the integrated controller, the integrated controller is arranged in the indoor thermal insulation box, one water inlet of the water mixing valve is communicated with the water outlet tube of the indoor thermal insulation box, and the other water inlet of the water mixing valve is communicated with the cold water inlet tube. The invention has the beneficial effects that the problem that an outdoor solar water heater has larger heat energy loss can be solved; the solar energy can be stored indoor through transporting the hot water, thus the utilization of the solar water heater can be maximized. In addition, the invention also solves the long-standing problem that cold water accumulated in the outlet pipeline affects the use of hot water in the solar energy industry; the system has simple structure, hot-water supply is stable, hot water with constant water temperature can be supplied at any time in 24 hours every day, thus the combination of economy, comfort, energy conservation and environmental protection can be realized.

Description

technical field [0001] The invention relates to a solar energy utilization technology, in particular to a solar water heater with an indoor heat preservation box. Background technique [0002] Solar water heaters are an outstanding representative of emerging renewable energy sources and have been widely recognized in recent years. However, because the realization of its functions depends on the weather, the stability of its hot water supply is often not guaranteed. This problem is more prominent in rainy weather or high-latitude alpine regions. Moreover, the outdoor installation of general solar water heaters leads to high heat loss, and the energy cannot be saved for a long time. And for a long time, because there is generally a lot of cold water in the outdoor pipeline of solar energy, it takes a long time to wait for the actual use, and it can be used normally after the cold water is drained, which wastes water and affects the comfort of use. A difficult point to be s...
