Problems solved by technology

The weak point of this patent is: the heat of the outside of the water container wall as the main body of heat generation cannot contact with water to exchange heat, and the heat loss is relatively large; The wall of the water container has a magnetic shielding effect on it, resulting in low heat generation; the inductance composed of the induction winding and the water container has a large active loss in the parallel resonant circuit, and it is difficult to achieve the best resonance state after being connected in parallel with the capacitor; The disadvantage of using a voltage regulator to supply power to the parallel resonant circuit is that a new energy-consuming device and manufacturing cost are added; the electric boiler made by this patent is a single-phase high-power electrical device, which will cause three-phase voltage imbalance to the power grid

Embodiment Construction

[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0062] figure 1 with figure 2 Shown is an induction heating pipe 30 composed of a heating steel pipe 8 . The heating steel pipe 8 is placed in parallel in the non-magnetic stainless steel water pipe 7 . There is a gap for circulating water between the outer diameter of the heating steel pipe 8 and the inner diameter of the non-magnetic stainless steel water pipe 7 . On the porous sealing plate 6 with flange, there are a plurality of water holes at the water gap between the heating steel pipe 8 and the non-magnetic stainless steel water pipe 7 . The porous fixed plate 19 is welded on the middle part of the heating steel pipe 8 earlier, and then welded on the middle part of the non-magnetic stainless steel water pipeline 7. The body pipeline of the heating steel pipe 8 is welded into one body after correspondingly penetrating through the ho...

Abstract

A main-frequency resonance type electric induction boiler is composed of the induction heater consisting of vertically arranged multiple induction heating tubes, a capacitor, an upper boiler cylinder or upper water collecting tank above said induction heating tubes, and a lower water collecting tank under said induction heating tubers. Said induction heating tube comprises a water tube, an internal heating steel tube and an external electromagnetic induction coil. When said induction heating tube is electrically and parallelly connected with said capacitor, a parallel resonance takes place to save electric energy by 50%.

Description

technical field [0001] The technical field that the present invention relates to is induction heating and parallel resonant circuit, especially relates to a kind of industrial frequency resonant induction electric boiler. Background technique [0002] In the existing electric boiler, what adopt is the heater that resistance type electric heating tube forms. Because the resistance heater absorbs 100% of the energy from the grid and converts it into heat during the heating process to heat water or other liquid media. Therefore, the power consumption of the electric boiler is relatively high, which is subject to certain restrictions in application. CN2440180Y Patent No. CN2440180Y announced by China Intellectual Property Office on July 25, 2001: In the electric hot water boiler and household water heater induction heating energy-saving device, a kind of electric boiler utilizing parallel resonant circuit to inductively heat water is disclosed. This patent uses a voltage regul...
