Upright type electric water heater

The utility model relates to an electric water heater, in particular to an upright type electric water heater. The upright type electric water heater comprises a casing, an upright type liner, an upright type electric heating pipe, a water inlet pipe of cold water and a water outlet pipe of hot water, wherein the periphery of the upright type electric heating pipe is provided with a sleeve barrel, an inner cavity of the sleeve barrel forms a heating hollow cavity, the side wall of the sleeve barrel is provided with a water inlet hole, the top of the sleeve barrel is provided with a water outlet, and the height of a water inlet of the water outlet pipe of the hot water is equivalent with the height of the water outlet at the top of the sleeve barrel. Because the periphery of the electric heating pipe is provided with the open type sleeve barrel in the upright type electric water heater disclosed by the utility model, the functions of heat storage and quick heating are realized. The open type sleeve barrel is provided with a convection hole, and the convection of the hot water is generated in the liner of the water heater during water storage and heating. When the water is used, the upright type electric water heater has the function of collecting the hot water so as to realize the function of quick heating. The bottom of the sleeve barrel is provided with a blow-down hole. When the water quality is bad and precipitates are formed, the precipitates can be discharged from the hole. According to the upright type electric water heater disclosed by the utility model, the waiting time required for preheating the cold water is greatly shortened, the yearly power consumption is reduced, and the aims of saving energy and reducing emission are achieved.
