Problems solved by technology
[0002] As far as the applicant knows, in order to maintain the pressure of outputting hot water, the existing water heater usually directly utilizes the pressure of the tap water pipe, but in this way, it is necessary to continuously fill the inner tank with cold water when outputting hot water, so that the original inner tank can be heated. The temperature of the hot water plummets, and it is necessary to continue heating to increase the temperature, which is undoubtedly a waste of resources

The invention relates to a photovoltaic water heater for improving the heat utilization rate. The photovoltaic water heater comprises a heat preservation inner container, a water mixing valve and a controller, wherein an electric heating pipe is arranged in the heat preservation inner container; a water inlet pipe communicated with an external tap water pipe and a water outlet pipe communicated with a hot water port of the water mixing valve are arranged at the bottom of the heat preservation inner container, a first electromagnetic valve controlled by the controller is arranged on the water inlet pipe, and a second electromagnetic valve controlled by the controller is arranged on the water outlet pipe; a cold water port of the water mixing valve is communicated with the external tap water pipe, and the water mixing valve is also provided with a water outlet; a water level lower limit sensor and a water lever upper limit sensor are arranged in the heat preservation inner container, wherein the signal output end of each of the sensors is electrically connected with the controller, and the sensors are positioned above the electric heating pipe; a booster pump is arranged on the top of the heat preservation inner container; and the controller is provided with a rechargeable battery, and the input end of the rechargeable battery is connected with the output end of a photovoltaic battery. By adopting the photovoltaic water heater, boiled hot water can be fully utilized; and cold water is prevented from being added when the hot water is discharged, so that resource waste is avoided.
Description
technical field [0001] The invention relates to a photovoltaic water heater for improving heat utilization rate, belonging to the technical field of water heaters. Background technique [0002] As far as the applicant knows, in order to maintain the pressure of outputting hot water, the existing water heater usually directly utilizes the pressure of the tap water pipe, but in this way, it is necessary to continuously fill the inner tank with cold water when outputting hot water, so that the original inner tank can be heated. The temperature of hot water plummets, and it is necessary to continue heating to increase its temperature, which is undoubtedly a waste of resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing problems in the prior art, provide a photovoltaic water heater with improved heat utilization rate, and avoid waste of resources by making full use of heated hot water. [0004] The...
