Abstract

The utility model discloses a conical electromagnetic oven which comprises a shell body, a high frequency induction heating coil arranged in the shell body, and a heating panel arranged on top part of the shell body, wherein a concave groove is arranged in the middle of the upper surface of the heating panel, the lower section of the concave groove is smaller than the upper section, the high frequency induction heating coil is arranged corresponding to the groove wall of the concave groove. As the concave groove is arranged in the heating panel, conical bottom cooking utensil with magnetic conductivity and sharp bottom can be placed in the concave groove; as the high frequency induction heating coil is arranged in the oven, vortex is formed in the conical bottom cooking utensil in the concave groove under the alternating magnetic field effect when the electromagnetic oven is turned on, then food in the cooking utensil is heated.

Description

Tapered electromagnetic oven

Technical field

The utility model relates to a kind of tapered electromagnetic oven.

Background technology

Electromagnetic oven has another name called electromagnetic stove, is the electric cooking apparatus that utilizes electromagnetic inductive heating principle to make, and it partly is made up of heating panel, high-frequency induction heating coil (being magnet exciting coil), RF power conversion equipment, controller etc.When electromagnetic oven uses, earlier the metal pot of magnetic conductance body is placed on the heating panel, in heater coil, feed alternating current then, just produce alternating magnetic field around the coil, the bottom of pot body that the magnetic line of force major part of alternating magnetic field is made by magnetic conductive metal, the bottom of pot body metal partly produces the electric current (being eddy current) of alternation, eddy current makes the iron atom high speed random motion in the bottom of pot body, atom runs foul of each other, rub and produce and cook necessary energy, because the thermal source in the above-mentioned heating process comes from the pan bottom rather than gives pan by conducting after the electromagnetic oven heating itself again, so the thermal efficiency exceeds nearly 1 times than the efficient of cooker in the past, and there is not naked light in the heating process, so safety, health, but the distance of pot body and heater coil can not be far away excessively during heating, otherwise the alternating magnetic field that heater coil produces can not effectively form eddy current in the pot body.The bottom of a pan of the frying pan of family expenses mostly is taper at present, but the heating panel of existing electromagnetic oven all is a plane in the market, can only utilize flat magnetic conductive metal cooker to cook, when cooker at the bottom of the points such as frying pan is placed on the heating panel, only there is the pot body with the panel contact portion can produce eddy current, thereby the effective interior food of heating kettle.

The utility model content

The purpose of this utility model is to provide a kind of tapered electromagnetic oven that can utilize point end magnetic conductivity cooker to cook.

For achieving the above object, tapered electromagnetic oven of the present utility model, comprise housing, be provided with the high-frequency induction heating coil in the housing, case top is provided with the heating panel, heating panel upper surface middle part is provided with groove, and the lower section of this groove is less than the cross section, top, the corresponding setting of cell wall of described high-frequency induction heating coil and described groove.

Groove is most advanced and sophisticated conical socket down.

Groove is the truncated cone-shaped groove.

The angle in the left and right sideline of the axis of groove and groove longitudinal section is all 30 ° to 80 °.

The axis of groove is a vertical line, and the left and right sideline of groove longitudinal section is straight line or curve.

Also be provided with a gas furnace on the housing.

The utlity model has following advantage:

Groove be arranged so that points such as frying pan at the bottom of the magnetic conductivity cooker can be placed in the groove; The part that point end cooker is placed in the groove that is arranged so that of high-frequency induction heating coil can be subjected to the effect of alternating magnetic field and produce eddy current when electromagnetic oven is opened, thus the food in the heating cooker.

2. groove is most advanced and sophisticated conical socket down, makes the utility model can utilize the taper cooker to cook.

3. groove is the truncated cone-shaped groove, makes the utility model can utilize the base to cook for the cooker of the sharp end on plane.

4. the angle of the left and right sideline of groove longitudinal section and recess axis is all 30 ° to 80 °, and most of taper cookers or truncated cone-shaped cooker can be put into wherein.

5. the axis of groove is a vertical line, and the left and right sideline of groove longitudinal section is straight line or curve, and the side that can make the longitudinal section is that the cooker of straight line or curve is put into wherein.

6. also be provided with a gas furnace on the housing, electricity consumption usefulness gas is all very convenient during use, and the user can select to make electricity consumption or combustion gas according to electricity price and gas price.
