The invention discloses a novel electric
water heater, belonging to the technical field of household appliance manufacturing. The novel electric
water heater mainly comprises a heat collecting chamber, an
electric heating pipe, a
control unit and a control chamber; the heat collecting chamber is arranged at upper part while the control chamber is arranged at the lower part; a dual-layered heat collecting tank is arranged in a heat
insulation layer of the heat collecting chamber, wherein the outer layer is a heat accumulating water tank while the inner layer is an inner heat collecting tank; the lower part of the heat accumulating water tank is provided with a running water inlet
pipe, the upper part of the heat accumulating water tank is provided with a water outlet
pipe, and the top part of the heat accumulating water tank is provided with a
safety valve; an end cover is arranged at the top part of the inner heat collecting tank; water, oil and other heat collecting fluid are stored in the inner heat collecting tank, the upper part of the inner heat collecting tank is provided with an automatic switch for automatically controlling the inflowing of the heat collecting fluid; the
electric heating pipe is arranged at the lower part in the inner heat collecting tank and is externally covered by an upright and relatively slim horn type air guide cover. The novel electric
water heater can actively guide flow and promote the heat collecting fluid such as
purified water flowing through the high-temperature
heat pipe to quickly flow upwards by using the
temperature difference; the novel electric water heater is greatly beneficial to collecting heat and preventing the running water from being in contact with the high-temperature
heat pipe, so that various hidden safety troubles such as scaling of the
heat pipe are avoided. The novel electric water heater is simple in structure, and more beneficial to safety and is easier to manufacture.
