Description
Technical field
The utility model relates to a kind of resistance wire structures more particularly to one kind can reduce resistance wire surface Working Temperature, prolong
Slow resistance wire oxidation, hence it is evident that improve the resistance wire structure in resistance wire service life and the electric radiation heater with the resistance wire.
Background technique
Electric radiation heater is a kind of kitchen appliance, since it is fast with heating speed, radiationless, does not choose pot, beautiful outline form
The advantages that sight, therefore application is become increasingly popular in people's lives, due to the difference of culinary art habit, cook gimmick and cooking time
Difference, therefore just to the service life of electric radiation heater, more stringent requirements are proposed.And the failure of electric radiation heater, exhausted big portion
Dividing is resistance wire failure.Existing resistance wire structure usually by the zigzag below the continous way resistance band and resistance band of top not
Continuous fixed part composition, discontinuous fixed part, which is inserted on chassis, is used to fixed resistance silk, the continous way being located above in structure
Resistance band is fever section.And core element of the resistance wire as electric radiation heater, failure procedure are general are as follows: resistance wire surface
High-temperature oxydation, oxide regions are thinning, resistance becomes larger, and oxide regions operating temperature increases, and oxide regions are more oxidizable, until resistance
Silk fusing failure delays resistance wire to aoxidize it follows that reducing resistance wire surface Working Temperature, is that the raising resistance wire service life is straight
Connect effective method.And the method for commonly reducing resistance wire surface Working Temperature (i.e. reduction resistance wire surface power density) has
Following two: first is that increasing resistance wire length, increasing resistance wire height simultaneously, resistance wire resistance can be kept constant in this way；Two
It is to reduce resistance wire thickness, increases resistance wire height, keeps resistance wire length constant.But since the cloth silk space in radiation disk has
Limit, while to guarantee the safe distance between resistance wire, the length of resistance wire unlimited cannot lengthen, simultaneously because existing resistance
Silk thickness minimum value be 0.05mm, have reached the limit of Economic Application, such as reduce resistance wire thickness again, not only difficulty of processing and
Cost will increase dramatically, simultaneously because its uniformity is worse with the reduction of resistance wire thickness, can reduce its service life instead.
Therefore it cannot achieve the purpose for extending resistance wire service life by above two method.
Summary of the invention
For the utility model mainly there is provided a kind of structure is simple, manufacturing cost is low, can reduce resistance wire surface work temperature
Degree, delays resistance wire to aoxidize, hence it is evident that the resistance wire structure in resistance wire service life and the electric radiation heater with the resistance wire are improved,
Solve it is existing in the prior art resistance wire surface Working Temperature can not be effectively reduced, cause resistance wire that high temperature oxygen easily occurs
Change, and further cause fusing failure, reduces the technical problem of service life of resistance wire etc..
