The specific embodiment
By describe in detail the present invention technology contents, structural feature, reached object and effect, below hereby exemplify embodiment and coordinate accompanying drawing to be explained in detail.
Refer to shown in Fig. 1 to 2, the invention provides a kind of energy-saving electric heating stove, comprise shell 10, inner bag 20, chamber door 30 and electro-heat equipment 40, described electro-heat equipment 40 is arranged in described inner bag 20, this chamber door 30 and described shell 10 chain connections, wherein:
Described inner bag 20 is sheet metal moulding high temperature resistant and that reflectivity is high, be coated among the shell 10 of described electric furnace, and with the space 11 of 10 one-tenth spacing of this outer hull shape; Described inner bag 20 is formed with cavity 23 by roof 21, diapire 22 and two corresponding sidewalls (not mark), and close described shell 10 1 side surfaces of described inner bag 20 are provided with a thermal insulation layer 24;
In order to strengthen effect of heat insulation, be also provided with a thermal insulation layer 24 at described shell 10 near these inner bag 20 1 side surfaces, wherein,
This thermal insulation layer 24 be coated on close described shell 10 1 side surfaces of described inner bag 20 with spraying method and/or this shell 10 on described inner bag 20 1 side surfaces, described thermal insulation layer 24 is thermal insulation coatings formation, and this thermal insulation coatings main component is nano-hollow ceramic fine bead and inorganic polymer.In the priority scheme of the invention, by this thermal insulation coatings the inner bag 20 that is applied in this electric furnace with spraying method near on described shell 10 1 side top layers and/or this shell 10 on described inner bag 20 1 side surfaces, can not only itself effectively part of heat energy be reflected back in cavity 23 by inner bag 20, and can also effectively intercept and itself conduct by inner bag 20 heat and lose by the thermal insulation layer on inner bag 20 or shell 10, thereby heat is concentrated in the inner chamber 23 of electric furnace, improve heat utilization rate in inner chamber 23, prevent that heat is transmitted on shell 10, user contacts shell because of carelessness and accidentally injures, thereby eliminate the security hidden danger while use.
As a kind of optimal way of the present invention, this thermal insulation layer 24 can also be a thermal isolation film 241, described thermal isolation film 241 be located on close described shell 10 1 side surfaces of described inner bag 20 in the mode of pasting and/or this shell 10 on described inner bag 20 1 side surfaces;
