Abstract
The utility model provides a ceramic electric heater, which is mainly composed of a ceramic heat conductor and electric heating wires, wherein the electric heating wires are arranged in an inner cavity of the sealed ceramic heat conductor and are arranged in a groove of the heating surface of the ceramic heat conductor for forming a loop, both ends of the electric heating wires are guided out of the heat conductor and a heat insulation layer is arranged between the upper wall of the inner cavity of the ceramic heat conductor and the electric heating wires. The utility model effectively reduces the dissipation of heat during heating process, increases heating efficiency and the use rate of electric energy, reduces energy consumption and heating cost, improves working environment and has simple structure and easy fabrication. The utility model is especially suitable for heating air in packing machines, food machines, baking ovens, baking passages, etc.
Description
Affiliated technical field
The utility model relates to a kind of electric heater, particularly a kind of ceramic electric heater that is used for air heat.
Background technology
At present, the ceramic electric heater that is used for air heat such as package packing machine, food machinery, baking oven, drying tunnel etc., it mainly is made up of ceramic heat conductor and heating wire, heating wire is preset in the ceramic heat conductor of sealing, and place the groove of ceramic heat conductor heating surface to form the loop heating wire, the two ends of heating wire cause outside the heat carrier, so that energized.Only need heating surface with ceramic heat conductor corresponding to heating place during use, get final product Fast Heating.Though that above-mentioned existing ceramic electrothermal device has is simple in structure, insulation, safety and the good advantage of anti-seismic performance, but because the back side of its heat carrier exposes in air, it is comparatively serious to dispel the heat, and exists following defective like this: the one, influenced firing rate, operating efficiency and utilization rate of electrical; The 2nd, increased energy consumption, wasted the energy, also increased heating operating cost simultaneously; The 3rd, the heat radiation at the heat carrier back side also makes ambient temperature raise aggravating working environment.
Summary of the invention
For overcoming the deficiencies in the prior art part, the utility model provide a kind of simple and reasonable for structure, effectively cut down the consumption of energy and improve the ceramic electric heater of the efficiency of heating surface.
The technical scheme that its technical problem that solves the utility model adopts is: it mainly is made up of ceramic heat conductor and heating wire, heating wire is preset at the inner chamber of the ceramic heat conductor of sealing, and place the groove of ceramic heat conductor heating surface to form the loop heating wire, the two ends of heating wire cause outside the heat carrier; Between the inner chamber upper wall of ceramic heat conductor and heating wire, be provided with heat-insulation layer.
Above-mentioned heat-insulation layer is alumina silicate fibre or high temperature resistant asbestos.
The beneficial effects of the utility model are: owing to set up heat-insulation layer between the heat carrier inner chamber upper wall of existing ceramic electric heater and heating wire, thereby reduced scattering and disappearing of heat in the heating process, improved the utilance of the efficiency of heating surface and electric energy, energy consumption and heating cost have been reduced, improved operational environment, and it is simple in structure, is easy to make.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
The utility model mainly is made up of ceramic heat conductor 1 and heating wire 3, and heating wire 3 is preset at the inner chamber of the ceramic heat conductor 1 of sealing, and heating wire 3 places the groove 2 of ceramic heat conductor 1 heating surface to form the loop, and its two ends cause outside the heat carrier 1.Be to increase the heat conductivility of heat carrier 1, on the outer surface of the working face of heat carrier 1, scribble high temperature far infrared glazed surface layer.Between the inner chamber upper wall of ceramic heat conductor 1 and heating wire 3, be provided with alumina silicate fibre (or high temperature resistant asbestos) heat-insulation layer 4,, improve the utilance of the efficiency of heating surface and electric energy to reduce heat leakage.
