Problems solved by technology

Its defect is that when the electric heating wire passes through the current, the electric heating wire generates electromagnetic waves, causing the adjacent electric heating wires to attract or repel each other, thereby causing a local short circuit, thereby reducing the resistance value of the electric heating wire, and reducing the power of the electric heater.

Embodiment Construction

[0012] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0013] Examples, see figure 1 and figure 2 Shown: a high-power electric heating device, including a heating wire 20, and the heating wire 20 has two ends 21. That is, there is one heating wire 20 . At the same time, the high-power electric heating device includes an insulating column 10, and the outer surface of the insulating column 10 is provided with grooves 11 distributed in a serpentine shape. At this time, the heating wire 20 runs through the groove 11 , and the two ends 21 are respectively located at two ends of the insulating column 10 . In this way, when the length of the heating wire 20 is increased, not only does it not need to increase the total length of the electric heater using the high-power electric heating device, but also, after electrification, the adjacent heating wires 20 will not have l...

Abstract

The invention discloses a large power electric heating device which comprises electric heating wires, wherein the electric heating wires are provided with tips; the large power electric heating device comprises an insulation column; grooves in snakelike distribution are arranged on the outer surface of the insulation column; the electric heating wires pass through inside the groove; and two tips of the large power electric heating device are respectively arranged at the two ends of the insulation column. The electric heating device has the advantages that the situation of partial short-circuit does not happen between electric heating wires under the condition of ensuring that the electric heating wires have larger resistances.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a high-power electric heating device. Background technique [0002] The main part of the electric heater is the heating wire. The heating wire has a certain resistance, and when a voltage is applied to both ends of the heating wire, the heating wire generates heat after the current passes through. Obviously, the greater the resistance value of the heating wire, the greater the power of the heating wire. In this way, when the diameter of the heating wire is fixed and the length of the electric heater is fixed, people expect to obtain a heating wire with a larger resistance value, so that a high-power electric heater can be produced. For this reason, there are heating wires that are distributed in a spiral shape. In this way, it is equivalent to increasing the length of the heating wire, thereby increasing the resistance of the heating wire. The disadvantage is th...
