The specific embodiment

By the technology contents, the structural feature that describe the utility model in detail, reached purpose and effect, below exemplify embodiment and conjunction with figs. now and know clearly and give explanation.

See also shown in Fig. 1 to 2, the utility model provides a kind of energy-conservation electric furnace, comprises shell 10, inner bag 20, chamber door 30 and electro-heat equipment 40, and described electro-heat equipment 40 is installed in the described inner bag 20, and this chamber door 30 is connected with described shell 10 hinges, wherein:

The sheet metal moulding that described inner bag 20 is high temperature resistant and reflectivity is high is coated among the shell 10 of described electric furnace, and with the space 11 of 10 one-tenth spacings 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, also be 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 constitutes for thermal insulation coatings, and this thermal insulation coatings main component is nano-hollow ceramic fine bead and inorganic polymer.In the priority scheme of the utility model creation, by this thermal insulation coatings and the inner bag 20 that is applied in this electric furnace with spraying method near on the described shell 10 1 side top layers and/or this shell 10 on described inner bag 20 1 side surfaces, can not only be by inner bag 20 itself effectively with in the part of heat energy reflected back cavity 23, and can also effectively intercept by inner bag 20 by the thermal insulation layer on inner bag 20 or the shell 10 and itself conduct the heat forfeiture that, thereby heat is concentrated in the inner chamber 23 of electric furnace, improve heat energy utilization rate in the inner chamber 23, prevent that heat is transmitted on the shell 10, the user contacts shell because of carelessness and accidentally injures, thereby eliminates the security hidden danger when using.
