Novel electric water heater

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of home appliance manufacturing. Background technique [0002] Current electric water heaters are mostly horizontal cylinders, and the heat source body electric heating tube is directly placed in the heated tap water in the inner tank. The surface area of ​​the electric heating tube is small and the temperature is high, so it is easy for the tap water to precipitate scale and adhere to the electric heating tube, seriously affecting The efficacy of electric water heaters, and even endanger the safety of electric water heaters. Contents of the invention [0003] The present invention aims at the above problems and provides a novel electric water heater. [0004] The technical solution of the present invention is: the present invention is mainly composed of a heat collecting chamber, an electric heating tube, a control unit and a control room. [0005] The present invention is an upright cylinder, which can...
