Abstract

The utility model relates to a bare electric heating element heating air media in a domestic appliance. The bare electric heating element comprises a metal frame in which a slim electric heating conductor is arranged, wherein the slim electric heating conductor is all bent into multiple segments which are connected with each other and is fixed on the metal frame via an insulation part. The utility model has the characteristics of high thermal efficiency, simple structure, easy manufacture, reliable insulation, easy assembly and good safety.

Description

The bareing electrical heating elements
Technical field
The utility model relates to a kind of bareing electrical heating elements that in household electrical appliance air dielectric is heated.
Background technology
The employed electrical heating elements that air dielectric is heated in the household electrical appliance, routine is a tubular heater, its general employing alloy material is heating wire (an electric heating conductor), and the periphery is filled with insulating heat-conductive pulverulent material (being generally the high-purity magnesium oxide powder), is sealed with metal tube again.Because have a plurality of heat conduction links the heating work face from heating wire to the metal tube surface, so its heat conduction loss is bigger, the heat efficiency is low.
Summary of the invention
The purpose of this utility model is that a kind of simple in structure, energy-efficient bareing electrical heating elements is provided.
Bareing electrical heating elements of the present utility model includes a metal frame, is provided with long and narrow electric heating conductor in metal frame, and whole long and narrow electric heating conductor bending is interconnective multistage, and electric heating conductor is fixed on the metal frame by insulating part.
The electric heating conductor of described each section can be positioned at same mounting plane, constitutes the flat structure; The electric heating conductor of each section also can constitute stereochemical structure not in a plane.
Described electric heating conductor can adopt band shape or spiral thread.
The utility model does not have unnecessary heat conduction path because electric heating conductor directly contacts with heat medium (as air), has eliminated the heat conduction losses in the structure, thereby has improved the efficiency of heating surface.Simultaneously, it is simple in structure, easily manufactured, insulation is reliable, be easy to installation, fail safe is good.
