When the dry-heating prevention temperature control protector fails, the electric heating tube 2 continuously heats up, and the overheat fusing protector arranged on the electric heating tube 2 thoroughly fuses and cuts off power after reaching fusing temperature, so that the safety protection of the device and electrical equipment using the device is realized
The utility model adopts the existing mature hardware stamping and stretching technology, mechanical processing technology, electric heating tube 2 manufacturing technology, aluminum profile extrusion technology and metal welding technology, and combines and applies the technologies, thereby being easier to realize industrial production; less material usage and a mature process also contribute to cost reduction.
In the design, the independent water passage is used for avoiding direct contact of water and corrosion of the electric heating tube 2, so that the safety is improved.
The water channel with the small cross section and the circuitous extension and the larger heating surface for heating the water channel are designed, so that the heat exchange efficiency of the water flowing in the water channel and the heating surface is improved, and the water can be rapidly heated.
The design uses a plurality of electrothermal tubes 2 which are independently heated, can realize different combinations of electric heating power under different use scenes, and simultaneously combines the control of the water flow speed in the water channel, thereby realizing the heating of water to different water outlet temperatures or the heating of water to steam under different use scenes.
In the design, a plurality of surfaces of the whole assembly are all metal without electrification and good in heat conduction, and the installation positions and installation devices of various temperature control and dry combustion protection units can be reserved according to the requirements, so that the reliability of temperature control and safety protection is improved.
The utility model relates to an electric heating device for rapidly heating water, which is simple in processing, stable in process and high in efficiency by processing all parts and applying the process technologies of extrusion, mechanical processing, hardware stamping and electric heating tube 2 manufacturing of the existing mature sectional materials. Meanwhile, all parts, including the outer tube of the electric heating tube 2, are made of aluminum alloy materials, and can be welded in one step through a tunnel furnace after combined installation, so that the electric heating tube has factory production conditions completely.

The relatively large heat exchange surface between the container of flowing water and the electric heating tube 2 improves the heat exchange efficiency and accelerates the heating of the flowing water in the water channel. The circuitous water channel in the container ensures that water flows in one direction, and the water is continuously and stably heated gradually in the process of flowing to the water outlet until the water outlet reaches the use temperature.
