The invention relates to a
solar water heater automatic adjustment device. A hot
water pipe is connected to the lower portion of a shell. A temperature sensor and an
infrared ray heating rod penetratethe wall of the shell and extend into an inner chamber of the shell. The upper portion of the inner chamber of the shell is provided with a temperature controller. An inner chamber of the temperaturecontroller communicates with the inner chamber of the shell through a hot water inlet. A cold
water pipe is connected to a cold water inlet of the temperature controller, extends out of the shell andis provided with a second one-way valve. A water outlet
pipe is connected to the top of the temperature controller, communicates with the inner chamber of the temperature controller and extends out of the shell. By means of the
solar water heater automatic adjustment device, the
water temperature can be adjusted automatically, and the temperature of output water is maintained to be constant; in addition, the temperature fluctuation of the output water is small and only + / -2 DEG C, and thus, the problem that a user is scalded or gets a cold due to the fact that the
water temperature is excessively high or low is avoided; when a
solar water heater is used in winter, the solar
water heater automatic adjustment device can output the hot water within two seconds, and the solar
water heater automatic adjustment device is convenient to use, and the
shower comfort level is effectively raised; and in addition, waste of
water resources is avoided, and 3-6 L of water can be saved each time.
