The present invention relates to a shielding device for an electronic cooker for cooking food by an induction magnetic field, and more particularly to a shielding device for an electronic cooker to exclude interference between adjacent countertops by placing an induction coil in a closed shielded plate. will be.

In the conventional electronic cooker, as illustrated in FIG. 1, the countertops 32 and 33 are installed on the upper surface of the cooker body 31, and the coils spirally wound on the coil fixing plates 34 and 35 of the countertops 32 and 33. When (36,37) is attached and current flows to the coils (36,37), an induction magnetic field is generated around the coils (36,37), and a container (magnet) can be attached to the coils (36,37). If you put a metal having a property of) to cook the food because the bowl is heated by the induction magnetic field.

However, such a conventional electronic cooker is a magnetic field generated around each coil (36,37) by the current (i) flowing in the coil (36,37) of two adjacent countertops (32,33) as shown in FIG. Self-interference in the part (dotted line) where the (solid line circle) is in contact, and therefore, when installing a plurality of countertops (32,33) due to this restriction requirements must be sufficiently maintained between the countertops (32,33) There was a problem that miniaturization of the.

In order to solve the above problems, the electronic cooker by induction magnetic field eliminates interference between coils of adjacent kitchen counters to prevent noise and close the spacing between kitchen counters. With reference to the accompanying drawings as to facilitate the description of the configuration and effect of the present invention in detail as follows.

First, referring to FIGS. 3 and 4, a constitution of the present invention includes a spirally wound coil 4 and 5 attached to an upper surface of the coil fixing disks 2 and 3 provided on the upper surface of the electronic cooker body 1. The ring-shaped shielding plates 9 and 10 formed integrally with the edges 7 and 8 covering the edge sidewalls 6 of the stationary disks 2 and 3 have a bolt hole 11 and a coil fixing disk plate at both ends thereof. 2,3) by fixing the bolt 13 through the bolt hole 12 at both ends to the upper surface of the electronic cooker body 1.

The effect of the present invention is that the induction magnetic field is generated by the current flowing through the coils 4 and 5 as shown in FIGS. 3 and 4, and the food is cooked by the induction magnetic field as in FIG. Detailed description is omitted because it is the content, but to describe the shielding action of the shielding plate (9,10) according to the present invention are as follows.

That is, as shown in FIG. 4, the coil 4 is located in the ring-shaped shielding plate 9, so that the magnetic field generated around the coil 4 exists only inside the shielding plate 9 and the shielding plate 9. Outside, the magnetic field is absorbed and blocked by the shield plate 9 so that the magnetic field does not exist.

Therefore, as shown in FIG. 5, even when the two countertops are in close proximity and the coils 4 and 5 are located close to each other, the magnetic field of the portion where the coils 4 and 5 are close by the shield plates 9 and 10 of each countertop is generated. Since it is shielded, the magnetic field does not exist between the shield plates 9 and 10 so that the coils 4 and 5 can be brought close to each other. Therefore, two countertops consisting of the coil fixing plates 2 and 3 and the shield plates 9 and 10 of the coils 4 and 5 shown in FIG. 3 can be installed in close proximity to each other.

Thus, according to the present invention, when installing a plurality of countertops of the electronic cooker can be installed by narrowing the interval between the countertops, it is possible to miniaturize the electronic cooker and to prevent noise generated from the coil, thereby improving the product quality.

In the coil fixing disc with spiral coil wound on the upper surface of the electronic cooker body, the ring-shaped ring (7,8) covering the edge sidewalls 6 of the coil fixing plate (2,3) is integrally formed. The shielding plates 9 and 10 are fixed to the upper surface of the electronic cooker body 1 by bolts 13 whose ends penetrate the bolt holes 11 and the bolt holes 12 at both ends of the coil fixing plates 2 and 3.
