Utility model content
The purpose of this utility model is the warming plate that proposes a kind of electric cooker of easy to assembly, reliable in quality.
The warming plate of electric cooker of the present utility model comprises outside jacket plates, cover plate, panel, wire-wrap board, base plate, heating wire and electric wire, and described panel, base plate and wire-wrap board are insulating mica plate; The edge of described outside jacket plates is provided with flanging, and so that panel, wire-wrap board, base plate are fixed between outside jacket plates and cover plate, described heating wire is around on wire-wrap board, and described electric wire is connected with heating wire, and is drawn by cover plate direction; Key is that described panel is provided with two and from face plate edge, to panel inside, extends to the bar v notch v of electric wire extraction location; Described cover plate is provided with two and from side edge thereof, to cover plate inside, extends to the bar shaped groove of electric wire extraction location; The flanging of described outside jacket plates shelters from the open-ended of bar v notch v and groove.
When assembling warming plate, first electric wire is connected with the heating wire on wire-wrap board, then in outside jacket plates, put into successively base plate, wire-wrap board, panel, cover plate, and make electric wire successively through the bar v notch v of panel, after the groove of cover plate, direction from cover plate is drawn, again the edge of outside jacket plates is bent to form to flanging, this flanging not only shelters from the open-ended of bar v notch v and groove, also base plate, wire-wrap board, panel, cover plate and outside jacket plates are fixed as one, base plate, wire-wrap board, panel, cover plate can not departed from simultaneously.In the process in assembling, traditional method is not worn electric wire insulating sleeve and cover plate, panel like that for another example, so production efficiency can significantly improve, and has reduced the probability that heating wire fractures yet.
Further, described cover plate is provided with the manhole communicating with groove in the end of groove, and described cover plate is protuberance structure at manhole place; Described warming plate also comprises the porcelain bead that is arranged at described protuberance structure place, and described electric wire is through porcelain bead.Described porcelain bead is fixed by protuberance structure, can arbitrarily not move, and porcelain bead will avoid electric wire by trough rim, worn and torn and fracture the trough rim isolation of electric wire and cover plate groove like this, has improved security.
Further, described electric wire consists of the silica gel parcel ferroalloy conductive core line that insulate, and has both guaranteed that product normally works under compared with elevated operating temperature environment, has guaranteed that again the electrical safety of product meets the requirements.
The warming plate of electric cooker of the present utility model, by bar v notch v and groove are set, has facilitated drawing of heating wire, and can reduce the possibility that heating wire fractures, and effectively extends the service life of heating wire, has good practicality.
