Description

Bonding Structure of Heated Element of Induction Heating Cookware

The present invention relates to an induction heating cooking vessel configured by attaching a heating element to the bottom of the cooking vessel, and in particular, to keep the bottom of the induction heating cooking vessel in a flat state so as to block interference with peripheral articles including a table. It relates to an adhesive structure of the heating element of the induction heating cooking vessel.

In general, an induction heating cooking vessel (hereinafter referred to as a cooking vessel) is a cooker that generates food by heating the food by generating an eddy current to the cooking vessel by a high-frequency magnetic wire generated by supplying a high frequency current to the heating coil, the bottom of the cooking vessel. The heating element is additionally attached to it to generate the eddy current.

In addition, the method of attaching the heated element to the bottom of the cooking vessel by the thermal spraying method has a disadvantage in that the productivity is lowered, in a state in which the heated element in the form of a substantially disk-shaped metal plate is placed on the entire bottom of the cooking vessel. A method of attaching by riveting has been proposed and is commercially available.

For example, according to the cooking vessel (Registration No .: 10-889722), as shown in Figures 1 and 2, as well as the appearance of the cooking vessel, a plurality of engaging projections 14 on the lower surface of the sequential sequential order Body portion 10 consisting of, and the heating element to be formed in each of the through-holes 32 along the corresponding position with the engaging projection 14 on the inner circumferential surface and coupled to the lower surface of the body portion 10 It consists of 30.

Accordingly, as shown in FIG. 2, a protrusion h passing through the through hole 32 is formed at the distal end of the coupling protrusion 14, and then the coupling protrusion 14 is inserted into the through hole 32 and pressed. 3, the protrusion h is formed along the outer surface of the through hole 32 to prevent the protrusion h from being separated.

However, the cooking vessel 100 is a state in which the convex portion (a) formed by the compression of the protrusion (h) is protruded along the outer surface of the through hole 32, so as to interfere with the peripheral article including the table. Due to the inconvenience in use, of course, there was a problem that damages the peripheral article.

In the process of using the cooking vessel 100, for example, when foreign matter such as oil is stuck to the outer surface of the heating element 30, the removal of the foreign matter is substantially performed due to the interference with the convex portion (a). As a result, it was difficult to delay the work load and the process, and there was a problem in that the hygiene was lowered.

Accordingly, the present invention is to solve the problems as described above, by maintaining the bottom surface of the induction heating cooking vessel in a flat state to avoid the interference of the induction heating cooking vessel in advance to prevent interference with the peripheral article including the table The purpose is to provide an adhesive structure of the heating element.

The present invention for achieving the above object; A body portion having a plurality of engaging protrusions disposed on the bottom surface as well as the cooking vessel; And a heated element adhesive structure of an induction heated cooking container formed of a heated element formed with a plurality of through-holes along a corresponding position with the engaging projection while facing the lower surface of the body portion. Engaging grooves are formed concave along the periphery of the engaging projection on the outer surface of the body portion, receiving grooves are formed in the outer surface of the heating element to be fitted into the engaging grooves along the periphery, the coupling It is formed in the upper end of the projection is configured to compress the projection via the through-hole to accommodate in the receiving groove.

As described above, the present invention has the following effects.

First, since the bottom surface of the cooking vessel is kept flat, the inconvenience of use caused by the interference of the protrusion and the peripheral article is eliminated as well as the damage caused by the friction with the peripheral article is prevented to extend the life.

Second, since the bottom surface of the cooking vessel is kept flat, it is possible to easily remove even if foreign matter is stuck to the heating element of the cooking vessel, thereby improving convenience and removing work load.

Body portion 10 having a plurality of engaging projections 14 are disposed on the bottom surface as well as the cooking vessel; And a heating element bonded to the induction heating cooking vessel including a heating element 30 formed with a plurality of through holes 32 along a corresponding position with the coupling protrusion 14 while facing the lower surface of the body portion 10. As a structure;

A locking groove 16 is formed concave along the periphery of the coupling protrusion 14 on the outer surface of the body portion 10, and the through hole 32 is surrounded on the outer surface of the heated element 30. A receiving groove 34 fitted into the engaging groove 16 is formed along the upper end of the coupling protrusion 14 to compress the protrusion h passing through the through hole 32 to accommodate the receiving groove. It is a structure accommodated in 34.

First, the cooking vessel 100 of the present invention is an induction heating cooking vessel configured by coupling the heated element 30 to the lower surface of the body portion 10, the coupling protrusion 14 formed on the body portion 10 ) And the coupling structure of the through hole 32 formed in the heated element 30 is characterized in that the bottom surface of the container is configured in a flat state.

And, the body portion 10, which accommodates food while forming the appearance of the cooking vessel 100, the space for accommodating the food, the rim portion 18 formed in the circumferential direction on the lower surface of the space, A plurality of coupling protrusions 14 formed in the inner space of the edge portion 18, and the engaging groove 16 is concave along the periphery of the coupling protrusion 14 on the lower surface of the space.

In addition, the edge portion 18 is preferably formed integrally along the circumferential direction on the lower surface of the body portion 10, even if a separate member is attached to the lower surface of the body portion 10 It is natural to be included in the category.

In addition, the coupling protrusion 14 is preferably formed by embedding in the groove formed in the inner side of the edge portion 18, even if formed integrally on the lower surface of the body portion 10 is naturally included in the technical category of the present application. Do.

At this time, the material of the body portion 10, including steel is not limited if the material is enough to withstand the heat source.

In addition, the shape of the locking groove 16 is preferably formed in a circular or polygonal shape so as to maximize the coupling force with the heating element 30.

The heating element 30 is attached to the bottom surface of the cooking vessel 100 to generate a eddy current, and adheres to the bottom surface of the body portion 10 in the edge portion 18. 36 and the plurality of through holes 32 formed in the close contact body 36 and into which the coupling protrusion 14 is inserted, and the through holes 32 are formed along the periphery of the engaging groove 16.
