Abstract
The utility model provides a technical proposal of a ceramic heater for an electric water heater, which mainly comprises an upper cover, a heating element, a heat insulation element and a lower cover which are connected with each other in series to be fixed by a connecting rod. The inner periphery of the heating element is uniformly distributed with a plurality of cylindrical through holes; the inner sides of the cylindrical through holes are provided with helical electric heating wires which are connected with wiring terminals. The scheme is characterized in that powdered magnesium is filled on the peripheries of the electric heating wires in the through holes of the heater and both ends of each of the through holes are provided with stoppers used for sealing. The utility model also has the concrete characteristic the ceramic outer surface of the heating element is also provided with a porcelain glaze with the function of far infrared emission by agglomeration.
Description
The utility model relates to electric heater parts in the household electrical appliance, especially a kind of electric heater ceramic heater.
The ceramic heater used of electric heater in the prior art, heating wire in its calandria is oxidized easily, and, heating wire is sagging after long-term heating causes the short circuit of heating wire and damages, the calandria of this structure is too short useful life, the performance of its heat exchange is also poor, this be existing in prior technology main between topic.
The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of electric heater ceramic heater technical scheme is provided, and this scheme can prolong the life-span of calandria, and can improve the heat exchanger effectiveness of calandria.
This programme is realized by following technical measures.Mainly including loam cake, calandria, insulator, lower cover is connected in series fixing by pitman, be evenly distributed with a plurality of cylindrical holes around in calandria, dress helical form heating wire is connected with binding post in it, the characteristics of this programme be in the through hole of described heater heating wire around be filled with the magnesium powder, and the sealing shutoff is arranged at the through hole two ends.Its concrete feature also has, and the ceramic outer surface of described calandria also sintering one deck has the enamel of far-infrared transmitting function.
According to as can be known to the narration of such scheme, owing to be full of the magnesium powder in the through hole that heating wire is housed on the ceramic heating body in this scheme, and the two ends of through hole have shutoff that it is sealed, this structure is just closed and fixed with the magnesium powder with the helical form heating wire of adorning in the through hole, heating wire can not be contacted again and anti-oxidation has improved heat transfer efficiency with the external world, heating wire is heated and also can produce sagging formation short circuit simultaneously, also improved the efficient of its heat exchange so increased the life-span of calandria, in addition, on the ceramic outer surface of calandria, sintering one deck have the enamel of far-infrared transmitting function, this has just further improved the ability of calandria heat exchange.This shows that the utility model compared with prior art has substantive distinguishing features and progress, its implementation result also is conspicuous.
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
Description of drawings:
Fig. 1 is the part sectional structure schematic diagram of the utility model embodiment;
Fig. 2 is the schematic top plan view of Fig. 1;
Fig. 3 is that the A-A of Fig. 1 is to the sectional structure schematic diagram.
By accompanying drawing as can be seen, the electric heater ceramic heater of this programme, mainly including loam cake 5, calandria 3, insulator 2, lower cover 1 is connected in series fixing by pitman 4, be evenly distributed with a plurality of cylindrical holes 10 around in calandria 3, dress helical form heating wire 6 is connected with binding post 8 in it, the characteristics of this programme be in the through hole 10 of described heater 3 heating wire 6 around be filled with magnesium powder 7, and sealing is arranged with shutoff 9 at through hole 10 two ends.Its concrete feature also has, and the ceramic outer surface of described calandria 3 also sintering one deck has the enamel of far-infrared transmitting function.
