Abstract
The utility model relates to a heating core of an electric heater, which comprises a heat conducting body and an electric heating wire. The electric heating wire is embedded in the heat conducting body; the heat conducting body is an integral member; the outer surface of the heat conducting body is coated with high-temperature far infrared base enamel. The utility model has the advantages that the structure of the utility model is very simple; heating speed is quick; the electric heating wire is completely embedded in the ceramic heat conducting body; insulating performance and anti-vibration performance are good; though the electric heating wire is used for a long time, after the electric heating wire is broken, heated liquid in the heater can not be charged; the utility model is safely used; after heating, power is cut and a water cooling electric heating wire is difficult to burst; the service life of the utility model is long.
Description
The utility model relates to the heating core of a kind of electric heater, particularly a kind of electric heater.
Heating core normally is arranged in the heater behind the overcoat heat pipe.The heating core of the electric heater of the prior art the most close with the utility model, it is the heating core in the homemade electric heater of method, its structure is: heat carrier is spliced for the multi-section type earthenware, the outer surface of earthenware is provided with annular groove, and heating wire twines and is embedded in the groove around the earthenware outer surface.The shortcoming of this structure is, heating wire is exposed to outside the earthenware, easily produces steam in the heat pipe, makes heating core moisture absorption conduction, and insulating resistance value is lower, bursts easily when running into outage water-cooled heating wire after the heating.Heating wire is once after the fracture, electrification phenomenon can appear in water heater, and security performance is relatively poor.Heating wire very easily absorbs the steam in the heat pipe and wears out poor seismic behavior in advance.Heating wire is easily softening after heating, and useful life is low.
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of heating core of simple in structure, electric heater that security performance is high is provided.
The technical solution of the utility model is, contains heat carrier and heating wire, and heating wire is embedded in the heat carrier.As a whole of heat carrier.The outer surface of heat carrier scribbles high temperature far infrared glazed surface layer.
The utility model has the advantages that heating wire is imbedded in the ceramic heat conductor fully, insulation property and anti-seismic performance are good, and heating wire is non-hygroscopic, and after both having made that heating wire is long-term and using aging fracture, the liquid that is heated in the heater can be not charged yet, uses as safe as a house reliably.Heating back outage water-cooled heating wire is difficult for bursting long service life.Heat carrier is an overall structure, and heating wire can be embedded in the heat carrier in advance, and structure is very simple, smooth surface.Because earthenware scribbles high temperature far infrared glazed surface layer outward, the electrothermal tube firing rate is fast.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
Below in conjunction with accompanying drawing the utility model embodiment further is described in detail:
The utility model contains heat carrier 1 and heating wire 2, and 2 one-tenth loops of heating wire are embedded in the heat carrier 1 in advance, and the end of incoming cables of heating wire 2 and leading-out terminal are located at outside the upside of heat carrier 1, so that external power supply.1 as a whole of heat carrier, casting after chemical method is dissolved for silica glass material forms.The outer surface of heat carrier 1 is provided with uniform stupefied groove, so that heat conduction.The material of heat carrier 1 also can be ceramic material.The outer surface of heat carrier 1 scribbles high temperature far infrared glazed surface layer.
Claims (3)
