Solar energy water heater with instantaneous heating function and self-stabilized output temperature

Abstract

The invention discloses a solar energy water heater with an instantaneous heating function and a self-stabilized output temperature. The solar energy water heater is composed of a water inlet pipe 1, a water inlet valve 2, a water inlet pipe 3, a solar energy heat collector 4, a communicating pipe 5, a water tank 6, a reducing valve 7, a water outlet pipe 8, a quick heating system 14, a water outlet pipe 15, a water outlet valve 16, a water outlet 17, a power source 13, a control system 10, a communicating pipe 18 and a cold water valve 19, wherein the control system 10 is connected with the water tank 6 through a wire 9, is connected with the quick heating system 14 through a wire 11 and a wire 12 and is connected with the water outlet valve 16 and the cold water valve 19 through a wire. When the solar energy water heater works, the control system 10 continuously detects the water level and the water outlet temperature of the water tank 6, continuously detects the water temperatures in the quick heating system 10, the water outlet pipe 15 and the water outlet pipe 17 at the same time, and automatically controls the heating power of the quick heating system 14, so that when the water outlet temperature of the water tank 6 is lower than a desired machine water outlet temperature, the water outlet temperature can be stabilized by real time heating compensation; and meanwhile, the control system 10 controls the cold water valve 19 to open or close, so that when the water temperature output of the water tank 6 is too high, cold water can be supplied to the water outlet pipe 17 through the communicating pipe 18 and the cold water valve 19 and the water outlet pipe 17 can output temperature stabled water by mixing cold water, wherein the communicating pipe 18 is communicated with the water outlet pipe 17.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a solar water heater with instant heating and temperature self-stabilizing output. Background technique [0002] Known public solar water heaters are almost all composed of solar collectors, water tanks and water tank heaters. When the weather is cloudy or in winter, when the solar radiation energy is not enough to produce hot water with sufficient temperature, the water tank heater is started to increase the water output. Temperature, there is a manual mixing valve near the water outlet to adjust the outlet water temperature. Due to the influence of water inlet mixing and water pressure in such water heaters, the outlet water temperature is very unstable, which brings inconvenience to bathing and may also cause high temperature damage to the human body. Contents of the invention [0003] The purpose of the present invention is to use the instant heating system to quickly compensate an...
