Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high frequency heating device, and more particularly to a high frequency heating device having a magnetic electromagnetic induction device configured to rotate a plate on which food is placed.

When food is heated using a high frequency generator such as a magnetron, a rotating plate is often used to prevent uneven heating.

There are two types of rotating plates: those that use the rotational force of an electric motor to rotate via a clutch, or those that rotate a disk by an electric motor and are placed on this disk, but the former The latter requires an engagement device such as a clutch, and the latter has a disc, which has the disadvantage that the opening cannot be used effectively.

In order to eliminate the above-mentioned drawbacks, the present invention provides a high-frequency heating device in which the plate is composed of a removable electric rotor and is directly rotated by an electromagnetic induction device. be.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 10 is an open housing having a high frequency generator (not shown), and a mortar-shaped recess 12 is provided in the bottom plate 11 of the open housing. An electromagnetic coil 13 that generates a rotating magnetic field is wound around the outside of this cone-shaped concave portion 12 to form an electromagnetic induction device. Further, a mortar-shaped turntable 15 is provided inside the mortar-shaped concave portion 12, and is provided with a coil, for example, a cylindrical coil 14, which is removably inscribed therein and to which a rotational force is applied by the electromagnetic coil 13. Next, the operation of this high frequency generator will be explained. First, the food 16 to be heated is placed on the turntable 15. Thereafter, when a switch connected to a power source (not shown) is turned on, the electromagnetic coil 13 is energized and a rotating magnetic field is generated. This rotating magnetic field generates an induced magnetic field in the cylindrical coil 14, inducing reverse activation, applying magnetic lift to the turntable 15, and rotating the turntable 15 under rotational force. If the high frequency generator is energized after this rotation starts, the food can be cooked evenly. After cooking, the turntable can be removed and the food can be transported directly to a dining table or the like. Note that the conical part 12 and the turntable 15
It is preferable to provide a pin at the center of each so that the relative positions of the two do not change, so that the magnetic characteristics are not disturbed. As described above, the present invention applies magnetism to the turntable using an electromagnetic induction device and rotates the turntable while floating, so the food placed on the turntable can be heated evenly, and the turntable can be heated evenly. You can also use the table as tableware. Further, it is possible to provide a simple and quiet turntable rotation mechanism that does not require mechanical parts for supporting the turntable. In addition, the outer periphery of the turntable has a conical shape that follows the concave part at the bottom of the oven, so the turntable rotates smoothly, and after cooking is completed, the turntable is always stable without becoming unstable due to the concave part. Because they are placed in close contact, there is no C that impairs the electromagnetic induction function, and the handling is extremely easy.
