Multifunctional solar water heater

Abstract

The invention discloses a multifunctional solar water heater. The multifunctional solar water heater comprises a bottom plate; a support plate is fixedly connected with the top of the bottom plate; asolar hot water tank is fixedly connected with the top of the support plate; a hot water pipe is communicated with the bottom of the solar hot water tank; a cold water pipe is communicated with the bottom, at one side of the hot water pipe, of the solar hot water pipe; and a thermoelectric power generation piece is fixedly connected between the hot water pipe and the cold water pipe. The multifunctional solar water heater relates to the technical field of solar equipment. According to the multifunctional solar water heater, the bottom end of the hot water pipe and the bottom end of the cold water pipe are fixedly connected with the top of the bottom plate through fixed blocks, and two functions of solar water heater and solar power generation are combined, so that the problem that existingsolar water heaters are low in energy conversion efficiency and bad in stability is effectively solved, and electric energy and hot water can be provided for families. The multifunctional solar waterheater is capable of providing hot water and electric energy for the families, is suitable for extensive families and has good development prospect.

Description

technical field [0001] The invention relates to the technical field of solar energy equipment, in particular to a multifunctional solar water heater. Background technique [0002] As we all know, solar energy is a green, clean and sustainable energy source. Now the utilization of solar energy has entered thousands of households. For example, many households have installed solar water heaters. However, this method of utilizing solar energy has obvious defects. First, the conversion efficiency of solar energy is not high. It can only convert solar energy into a single heat energy. In the season with strong sunlight, when the water in the water heater is heated to a higher temperature, the water temperature will not rise again. In this case, the efficiency of absorbing solar energy is greatly improved. This is undoubtedly a waste of resources. Second, poor stability. The biggest defect of solar water heaters is that they "depend on the weather". In cloudy, rainy and insuffic...
