Description

Integrated Electric direct heater

The utility model relates to a kind of electric heater, relates in particular to a kind of integrated Electric direct heater.

Progress along with science and technology, the continuous increase-volume of China's energy output, use the occasion of electric heating appliance more and more, for example electrothermal furnace, electric kettle, electric food warmer etc., though having to reach, existing electric heating appliance make electricity consumption generate heat, make the improved advantage of environmental pollution, but because therefore the problem of its electric heater structure, exists following shortcoming:

1. electrothermal furnace, as shown in Figure 1 and Figure 2, be made of drain pan 21, insulating carrier 23, the heating wire 24 and the plug 25 that are embedded in the insulating carrier 23, what have is provided with one deck cover plate 22 on insulating carrier, with the convenient utensil that is heated of placing, but this electrothermal furnace, heating wire directly exposes to the open air outside, even cover plate is arranged, also be by air insulation, carelessness is arranged slightly, easily cause electric shock, have unsafe factor in the use; Simultaneously, this electrothermal furnace is that the heat efficiency is low by the air transmitted heat.

2. though its electric heater such as electric kettle and electric food warmer is encapsulated in heating wire in the housing, the electric heater in the electric kettle for example, as shown in Figure 3, comprise tubular shell 31, the heating wire 32 that in tubular shell 31, is provided with, by the megohmite insulant 34 that is provided with between the double-end plug 35 of heating wire and heating wire and housing in order to insulation; The electric heater in the electric food warmer for example again, as Fig. 4, shown in Figure 5, comprise go to the bottom 41, loam cake 42, insulating carrier 43, be located in the insulating carrier heating wire 44 and with so that the megohmite insulant 45 that heating wire and housing insulate; More than two kinds of electric heaters, though between housing and heating wire, filled for example magnesia powder of megohmite insulant, can reach the effect of insulation, the coefficient of heat conduction of magnesia powder is low, so the heat efficiency reduces; Simultaneously, year in and year out,, make heating wire skew contact housing, promptly electric shock accidents can take place if magnesia powder has corrupted.

The purpose of this utility model is exactly in order to overcome the shortcoming of electric heater in the existing electric heating appliance, and propose a kind of simple in structure, easy to make, safe and reliable and heat conduction is fast, the heat efficiency is high integrated Electric direct heater.

The purpose of this utility model is achieved in that integrated Electric direct heater, comprise: housing, this housing comprises goes to the bottom and loam cake, be installed in the insulating carrier of housing in going to the bottom, be located at the heater on the insulating carrier, keep certain clearance between this heater and the loam cake, and, draw outside housing to connect the exit of power supply by these heater two ends; It is characterized in that: be filled with between described heater and the loam cake can make heater and insulating carrier combine closely, and and loam cake between remain fixing distance, simultaneously make loam cake and bottom along be tightly connected heat conduction encapsulate binding material.

Above-mentioned integrated Electric direct heater, wherein, described heater is a heating wire.

Above-mentioned integrated Electric direct heater, wherein: described heater is an Electric radiant Heating Film.

Above-mentioned integrated Electric direct heater, wherein: described heat conduction encapsulation binding material is a glass material.

Above-mentioned integrated Electric direct heater, wherein: described loam cake is the heat conduction flat board.

Above-mentioned integrated Electric direct heater, wherein: described loam cake is slightly curved metallic plate.

Above-mentioned integrated Electric direct heater, wherein: described loam cake is a frying pan.

Above-mentioned integrated Electric direct heater, wherein: described loam cake is a pan.

Above-mentioned integrated Electric direct heater, wherein: the surface of described insulating carrier is level and smooth.

Above-mentioned integrated Electric direct heater, wherein: the surface of described insulating carrier is provided with groove.

Because the utility model has adopted above structure, heater and carrier are fixed the position of heater in housing according to the encapsulation binding material, the structure that makes it to become one, safe and reliable in guaranteeing to use, and can increase the service life; Again, the loam cake of its housing is sealed by the encapsulation binding material with going to the bottom, and is not afraid of humidity and washing, therefore can use in all case.
