Photoelectric complementary solar water heater

Abstract

The invention discloses a photoelectric complementary solar water heater, which comprises a support, a heat collector tube, a water tank, a temperature controller and a tap water port. The heat collector tube used for realizing solar and thermal conversion is arranged on the support, a heat exchange tube is arranged in the water tank, the tap water port is communicated with a water inlet of the heat exchange tube by a first branch tube, communicated with the water tank by a second branch tube and joined with an output pipeline of a water outlet of the heat exchange tube by a third branch tube, a quick heater with a built-in electric heating element is connected with the joined pipeline, an outlet of the quick heater is connected with a shower, a temperature sensor is disposed on the joined pipeline, a first electromagnetic valve corresponding to the temperature sensor is arranged on the third branch tube, and the temperature controller controls opening and closing of the first electromagnetic valve according to water temperature signals of the temperature sensor. The photoelectric complementary solar water heater has the advantages of constant water temperature, sufficient water pressure and fresh water.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a solar water heater which utilizes sunlight and electric heating to perform complementary work. Background technique [0002] Traditional solar water heaters will have low water temperature during continuous cloudy days or long winter days, which will affect the bathing effect. So there is a "light energy + electric energy" complementary solar water heater. [0003] However, general solar water heaters need to frequently adjust the ratio of hot water and cold water when taking a bath, so that the bath can reach a comfortable temperature. If the water heater can reach a constant temperature, it can reduce the trouble caused by frequent debugging. [0004] General solar water heaters are installed on the roof, and the insulating water tank of the solar water heater has a certain distance from the user's bathing position. Like this, before bathing water at every turn, the cold water in th...

Problems solved by technology

[0006] The temperature of the hot water in the heat preservation water tank of general solar water heaters is kept between 20 and 100 °C for a long time, and the hot water inside is recycled for a long time, which will cause more scale, impurities and bacteria in the water tank, which will affect the health of users.
