The specific embodiment

In conjunction with the accompanying drawings, specific embodiment of the utility model is described.

Automatic temperature-control electric oven as shown in Figure 1 is used for family, comprise that mainly housing 10, controller (adopt existing mature technology, comprise controllers such as temperature, time), has a single inner chamber in the housing, the heating part that the roasting plate 18 of electricity is set and is made of insulation insulating barrier 4 and induction coil 5 in inner chamber 3 is provided with variable frequency induction power supply (SB) 1 in the housing 10.The top or the bottom of the roasting plate 18 of electricity are provided with insulation insulating barrier 4 and induction coil 5, and induction coil 5 is arranged on the bottom of insulation insulating barrier 4, and the roasting plate 18 of electricity is arranged on the skin of insulation insulating barrier 4.On the roasting plate 18 of the electricity of bottom a barbecue rack 8 can be set, be mainly used in food roasting.Variable frequency induction power supply (SB) is arranged on the side or the bottom of furnace chamber, the outer setting insulation thermal insulation ceramics plate 17 of electro-magnetic screen layer 6.Induction coil 5 is connected with supply socket 9 by variable frequency induction power supply (SB) 1.At the electro-magnetic screen layer 6 of induction coil with outer setting one deck anti-electromagnetic radiation of insulation insulation material layer, or the nano material that scribbles except that electromagnetic radiation at cabinet inside is provided with controller panel 2 in the side of furnace chamber, automatic thermostat 14, temperature controller and infrared receiving terminal 16 are set respectively on it, and temperature controller is connected with temperature sensor 6 in being arranged on housing 9.

As shown in Figure 3, it is fit to the electric oven that large-scale occasion is used, and is provided with a plurality of baking boxs in housing, and the structure of each baking box is identical with the structure of single baking box shown in Fig. 1,2.
