Description
Technical field
The present invention relates to a kind of warming plate of electric cooker.
Background technology
Present electric cooker utilizes warming plate to realize heat insulation function mostly, traditional warming plate comprises electrical lead, outside jacket plates, cover plate, insulation mica panel, base plate and the inner mica wire-wrap board that is wound with resistance wire, wherein panel, wire-wrap board, base plate are located between outside jacket plates and cover plate, the correspondence position of panel, wire-wrap board, cover plate is equipped with through hole, the two ends of the resistance wire electrical lead of plugging into from through hole, electrical lead is that heat-resisting stainless steel bare wire adds and wears fiberglass sleeve, is connected with electric rice cooker circuit by electric wire and terminal.The resistance wire of above-mentioned warming plate is connected with electrical lead after being wound around will wear panel, cover plate, fiberglass sleeve, not only operating difficulties production efficiency is low, resistance wire is easily fractureed, and fiberglass sleeve is withstand voltage low, adds to wear big or small two-layer sleeve pipe and also often occur withstand voltage defective phenomenon.
Summary of the invention
The object of the invention is to propose a kind of warming plate of electric cooker of easy to assembly, reliable in quality.
The warming plate of electric cooker of the present invention 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 bar v notch vs that extend to electric wire extraction location from face plate edge to panel inside; Described cover plate is provided with two bar shaped grooves that extend to electric wire extraction location from side edge thereof to cover plate inside; The flanging of described outside jacket plates shelters from the open-ended of bar v notch v and groove.
In the time of 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 after the groove of the bar v notch v of panel, 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 be departed from simultaneously.Due in the process of assembling, traditional method is not worn electric wire insulating sleeve and cover plate, panel like that for another example, and therefore production efficiency can significantly improve, and has also reduced the probability that heating wire fractures.
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, by the trough rim isolation of electric wire and cover plate groove, avoid electric wire worn and torn by trough rim and fracture like this, has improved security.
Further, described electric wire is made up 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 invention, 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.
