Insulation construction is not take up complete machine material and resource (such as liner, shell and production scene by the way of fission foaming
Deng), and the insulation construction that split production is completed can be assembled directly with liner and shell, and the production of complete machine is effectively increased
Efficiency；In addition, the problem of effectively preventing casing deformation caused by foaming process and liner offset.
As the optimal technical scheme of electric heater, the insulation construction includes insulating layer, is arranged in the insulating layer
The inside protective layer of side and the outside protective layer being arranged on the outside of the insulating layer.
As the optimal technical scheme of electric heater, the insulation construction includes insulating layer and is arranged in the insulating layer
The inside protective layer of side.
As the optimal technical scheme of electric heater, the inner cavity of the inside protective layer is mutually fitted with the shape of the liner
Match.
As the optimal technical scheme of electric heater, the insulation construction includes insulating layer and is arranged outside the insulating layer
The outside protective layer of side.
As the optimal technical scheme of electric heater, the inner cavity of the insulating layer is adapted with the shape of the liner.
As the optimal technical scheme of electric heater, the insulating layer is VIP or aeroge.
As the optimal technical scheme of electric heater, the inside protective layer is polyurethane or foamed plastics.
As the optimal technical scheme of electric heater, the outside protective layer is polyurethane or foamed plastics.
The present invention compared with the prior art the utility model has the advantages that
1) electric heater provided by the invention is refilled after insulation construction foaming and is assigned between shell and liner, no
Complete machine material and resource (such as liner, shell and production scene) are occupied, and the insulation construction that split production is completed can be direct
It is assembled with liner and shell, effectively increases the production efficiency of complete machine；In addition, effectively preventing outer caused by foaming process
The problem of shell deformation and liner offset.
2) electric heater provided by the invention, insulation construction include insulating layer, inside protective layer and/or outside protection
Insulating layer can be isolated with liner for layer, inside protective layer, and liner is avoided to generate friction damage, outside protective layer energy to insulating layer
It is enough that insulating layer is isolated with shell, avoid shell from generating friction damage to insulating layer, effectively increase insulation construction uses the longevity
Life and heat insulation effect.

Specific embodiment
Technical solution of the present invention is further illustrated with embodiment with reference to the accompanying drawing.It is understood that this place
The specific embodiment of description is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to
Convenient for description, in attached drawing, only the parts related to the present invention are shown and it is not all.
Embodiment one
As shown in Figure 1, the present embodiment provides a kind of electric heater, including shell (not shown), liner 10 and heat preservation
Structure 20 is refilled after 20 foaming of insulation construction and is assigned between shell and liner 10.
Insulation construction 20 is not take up complete machine material and resource (such as liner 10, shell and production by the way of fission foaming
Scene etc.), and the insulation construction 20 that split production is completed can be assembled directly with liner 10 and shell, be effectively increased whole
The production efficiency of machine；In addition, the problem of effectively preventing casing deformation caused by foaming process and the offset of liner 10.
In the present embodiment, insulation construction 20 includes insulating layer 21, the inside protective layer 22 that 21 inside of insulating layer is arranged in
With the outside protective layer 23 that 21 outside of insulating layer is arranged in, wherein the inner cavity of inside protective layer 22 and the shape of liner 10 are mutually fitted
Match, insulating layer 21 can be isolated with liner 10 for inside protective layer 22, and liner 10 is avoided to generate friction damage to insulating layer 21；Outside
Insulating layer 21 can be isolated with shell for side protective layer 23, and shell is avoided to generate friction damage to insulating layer 21.By internal layer with
Shape add protection, middle layer heat preservation, outer layer protection structure setting, can effectively improve insulation construction 20 service life and heat preservation effect
Fruit.
Further, insulating layer 21 can be VIP, VIP (Vacuum Insulation Panel), also known as vacuum insulation
Plate is one of vacuum thermal insulating material, is to be combined by filling core material and vacuum protection surface layer, can be effectively prevented from air
The transmitting of heat caused by convection current, compared with other materials, VIP has with its extremely low thermal coefficient when heat preservation technology requires identical
Have the advantages that 21 thickness of insulating layer is thin, small in size, light-weight, and there is environmental protection and energy-efficient characteristic.Certainly, insulating layer
21 material is not limited to VIP, can also be other high-efficiency insulated materials such as aeroge.
Inside protective layer 22 and outside protective layer 23 are using easily molded material, polyurethane and bubbles such as polyurethane or foamed plastics
