Description

The hot stove Electrothermic wire of a kind of spoke

Technical field

The utility model relates to the hot stove element of a kind of spoke, particularly a kind of hot stove of spoke that is installed in, the hot stove Electrothermic wire of the energising back uniform spoke of heat radiation.

Technical background

The hot stove of spoke is a kind of household electrical appliance of simple and durable, the heating wire established in it energising back heating, the thermal radiation devitrified glass to the stove, and, realize boiling of food by this devitrified glass heat conduction.

Heating wire of the prior art is the conductive elongate band, its mode that is installed in the hot stove of spoke is that the some long limit of this conductive elongate band is uprightly inserted on the thermal insulation and electrical insulating material pedestal in the electric heater, for guarantee heating wire can add firmly insert as, prior art is interval with fixing chimb on the long limit of inserting pedestal, the similar pin of described chimb inserts in the pedestal, and its fixed effect is obvious.

But the fixedly setting of chimb, make that fixedly the conductive area at chimb place increases, resistance value reduces, cause the resistance of heating wire of elongated band inhomogeneous everywhere, and the heating wire resistance value is inhomogeneous, will make it in the heating process, when particularly just having started working, spoke heat is inhomogeneous, influences operating efficiency and heats.

The utility model content

The purpose of this utility model is even, the hot stove Electrothermic wire of the uniform spoke of heat radiation of a kind of heating wire resistance value of design.

In order to solve the problems of the technologies described above, the utility model comprises following technical scheme: the hot stove Electrothermic wire of a kind of spoke, comprise conductive elongate band with the first long limit and second long limit, be interval with the chimb of a plurality of fixedly conductive elongate bands on the described first long limit along its length, it is characterized in that: be provided with the concave edge that parallels with chimb along its length on the second long limit, described elongated with going up in the longitudinal cross-section of the longitudinal cross-section of concave edge size and non-concave edge consistent size.

Further, in order to increase heating wire and pedestal connection stability, described chimb top is provided with fixing hole.

Further, the base of described chimb and concave edge is a level, and the chimb base and first long limit smooth connection of circular arc; The described concave edge base and second long limit smooth connection of circular arc.

The concrete shape of described chimb and concave edge also can be circular arc or zigzag.

Compared with prior art, owing to be interval with the chimb of a plurality of fixedly conductive elongate bands on the first long limit along its length, and the utility model is provided with the concave edge that parallels with chimb along its length on the second long limit, thereby kept heating wire conductive elongate band in the longitudinal direction everywhere height H equate, and, because Electrothermic wire is elongated band, its thickness is even, therefore everywhere longitudinal cross-section size is all consistent on the Electrothermic wire, also just be equivalent to have guaranteed on the heating wire entire length that resistance value everywhere is evenly to equate, its heat radiation is even, thereby has avoided the temperature imbalance of heating wire part, the useful life of further having improved heating wire.

Embodiment

The heating wire of the hot stove of spoke is the conductive elongate band, its mode that is installed in the hot stove of spoke is that the some long limit of conductive elongate band is uprightly inserted on the pedestal of thermal insulation in the electric heater and electrical insulating material, the elongated long limit with 1 insertion pedestal of heating wire lead is the first long limit 2 in the specific embodiment, the long limit of another one is the second long limit 3, for described lead is elongated with on the 1 more firm insertion pedestal, on the first long limit 2, be provided with chimb 4, above-mentioned chimb 4 plays the effect of element legs, make in the convenient insertion pedestal of conductive elongate band energy, also guaranteed the firm and stable of insertion.

But after having established chimb 4 on the first long limit, conductive elongate band 1 will change in the resistance value of this position and since chimb 4 be provided with that to have increased lead elongated with 1 herein conductive area, resistance value is herein diminished.If after at interval a plurality of chimbs 4 being set on the conductive elongate band, will cause conductive elongate band resistance value everywhere inhomogeneous, it is inhomogeneous that so also shadow plays the radiation temperature of the hot stove of spoke, and inhomogeneous on this temperature also influenced useful life of conductive elongate band 1.

Fig. 1 is the part schematic diagram of conductive elongate band among the utility model embodiment 1, is interval with along its length on the described first long limit 2 on chimb 4, the second long limits 3 of a plurality of fixedly conductive elongate bands 1 and is provided with the concave edge 5 that parallels with chimb 4 along its length.The base of chimb 4 and concave edge 5 is a level among the embodiment 1, and protruding 4 bases and first long limit smooth connection of 2 circular arcs; Described groove 5 bases and second long limit smooth connection of 3 circular arcs, kept like this heating wire conductive elongate band in the longitudinal direction everywhere height H equate, because heating wire is elongated band, its thickness is even, therefore everywhere longitudinal cross-section size is all consistent on the Electrothermic wire, also just is equivalent to have guaranteed on the heating wire entire length that resistance value everywhere is evenly to equate.

In order to increase the stable shape that heating wire is connected with pedestal, described chimb 4 tops are provided with fixing hole 6.Because fixing hole 6 is apertures going out on chimb 4 tops, so very little to resistance value influences herein.

The part schematic diagram of conductive elongate band 1 among Fig. 2, Fig. 3 the utility model embodiment 2,3, the places different with embodiment 1 are, chimb 4 and concave edge 5 are circular arc or zigzag, but identical is, kept heating wire conductive elongate band in the longitudinal direction everywhere height H be equal because heating wire is elongated band, its thickness is even, therefore everywhere longitudinal cross-section size is all consistent on the Electrothermic wire, also just is equivalent to have guaranteed on the heating wire entire length that resistance value everywhere is evenly to equate.The foregoing description 2,3 all is the design about chimb 4 of the present utility model and concave edge 5 profiles; in fact; no matter how the profile of chimb 4 and concave edge 5 changes; as long as can keep heating wire conductive elongate band in the longitudinal direction everywhere height H equate; guaranteed on the heating wire entire length that resistance value everywhere is evenly to equate, promptly dropped on protection range of the present utility model.
