Description
The utility model relates to a kind of power frequency electromagnetic oven, specifically is multi-functional power frequency electromagnetic oven.
The most function singleness of present existing power frequency electromagnetic oven can only be cooked, and the thermal efficiency is low, mostly is heater-type greatly, and complex structure uses maintenance inconvenient in addition.
The purpose of this utility model is to propose a kind of simple in structure, the multi-functional power frequency electromagnetic oven that the thermal efficiency is high, but not only can cook but also cooking, roast food etc., safe and convenient to use, save electric energy.
The utility model major technique content is, multi-functional power frequency electromagnetic oven is by body of heater, control circuit constitutes, body of heater comprises Stainless steel pot cover 1, stainless-steel pan body 2, aluminium shell 3, heat-resisting heat-insulation layer 4, Stainless steel pot cover 1 covers on stainless-steel pan body 22, stainless-steel pan has covered steam vent 7 and pot cover handle 11, be welded with the shorting link B of projection around the stainless-steel pan body upper edge, shorting link A is housed around the stainless-steel pan bottom, fluted around the top of shorting link A, around the stainless-steel pan body and shorting link A heat-resisting heat-insulation layer 4 is housed on every side, be between temperature control in the shorting link A, temperature controller 8 is housed between temperature control, shorting link A outside is with the iron core of toroidal transformer 5 and around top once (elementary) coil, aluminium shell 3 wraps in stainless-steel pan body 2, heat-resisting heat-insulation layer 4, shorting link B, the iron core outside of A and toroidal transformer 5, be connected as a single entity by the fixing card 6 of transformer, aluminium shell 3 and stainless-steel pan body 2 are by shorting link A, B constitutes secondary (secondary) coil of short circuit circle as toroidal transformer, between aluminium shell and the stainless-steel pan body control circuit board 10 is housed, and is connected for 220 volts with interchange by socket 9.
Technique effect of the present utility model is, because multi-functional power frequency electromagnetic oven pan body is the stainless-steel pan body, therefore cooking to cook with it has no side effect safety and sanitation; Pot body heating is to realize that by the closed-loop path that stainless-steel pan body, shorting link and aluminium shell form because the stainless-steel pan bulk resistor is very big, the aluminium Shell resistance is very little, thus most of heat exhaustion on the stainless-steel pan body, so thermal efficiency height; This electromagnetic oven is equipped with control circuit in addition, can finish other functions such as cooking, barbecue etc. by control circuit except that cooking.Control circuit is simple in structure, uses easy to operate.
