The conventional microwave oven includes a front plate 1 provided with a door (not shown) so as to be openable, a cavity 2 forming a cooking chamber, and a rear plate 7 forming a rear surface of the microwave oven.

The cavity 2 includes a side plate 3, a bottom plate 4, and a top plate 5. The side plate 3, the bottom plate 4 and the top plate 5 are coupled to each other so that a cooking cavity can be defined inside the cavity 2. [ At this time, the top plate 5 may be integrally formed with the bottom plate 4 and the side plates 3. [

An electric field chamber is formed on the outer side of the cavity 2, and the rear plate 7 is disposed on the rear side of the electric field chamber. The rear plate 7 is provided with electric parts or the like which are difficult to be directly installed inside the cavity 2 and a through hole 32 for air flow in the electric chamber can be formed.

The cavity (2) includes a bottom portion forming the bottom surface of the cavity (2) and side portions extending from both sides of the bottom portion.

According to the conventional cooking apparatus, when the cavity (2) is manufactured, a clearance is generated when the bottom part and the side part are assembled, and when the gap is welded, the welding part is easily exposed to the outside.

In addition, in the process of painting after the welding of the bottom part and the side part, the paint flows outwardly of the cavity through the gap, and thus the welding part, that is, the joint part of the bottom part and the side part The appearance of the inside of the cavity becomes rough.

As a result, there has been a problem that the reliability and satisfaction of the user's product is lowered.

The lower surface portion 110 includes a lower surface main body 111 forming a lower outer surface of the cavity 100 and a second outer extending portion 112 extending in an outer direction of the lower surface main body 111 .

The side part 130 includes a side part body 131 forming a side surface of the cavity 100 and a first outside part 132 extending outward from the side part body 131.

The side portion main body 131 and the first outside extension portion 132 may be integrally formed and the first outside extension portion 132 is bent from the side portion main body 131 and extends in the outward direction .

The second outer extension 112 is coupled to the lower outer side of the first outer extension 132. The second outer extension portion 112 is formed with a first coupling portion 113 to be coupled with the first outer extension portion 132. The first outer extension portion 132 is formed with a second coupling portion 133 coupled to the first coupling portion 113.

The first engaging portion 113 and the second engaging portion 133 may be re-betted by a predetermined fastening member. However, the combining method is not limited thereto.

The gap portion 120 may be formed between the second outer extension 112 and the first outer extension 132 in the process of coupling the lower portion 110 and the side portion 130. The gap portion 120 can be understood as a boundary region or a gap region at a portion where the lower surface portion 110 and the side surface portion 130 contact each other.

The gap portion 120 may be formed at a portion bent from the side portion main body 131 to the first outside extension portion 132.

A protrusion 115 for shielding the gap 120 is provided on one side of the gap 120, specifically, inside the gap 120. The protrusion 115 may be formed at a rim portion of the lower surface main body 111 and may be positioned on the inner side of the side body 131 and coupled to the lower end of the side body 131.

The projecting portion 115 can be understood as a constitution in which at least a part of the lower surface main body 111 protrudes upward. The protrusion 115 may be formed by forming the lower surface main body 111 in a forming process.

The upper end of the protrusion 115 may be formed at a position higher than the gap 120. The protruding portion 115 is disposed at a higher position than the lower surface main body 111 and the second outer extending portion 112.

A welding region 117 is defined at a portion where the protrusion 115 and the gap portion 120 are coupled. After the bottom portion 110 and the side portion 130 are coupled so that the protrusion 115 shields the gap portion 120, welding is performed at a portion where the protrusion portion 115 and the side portion main body 131 abut each other Lt; / RTI >

After the welding, the bottom surface 110 and the side surface 130 may be painted using a paint of a predetermined color for finishing. In this process, the liquid paint can be prevented from flowing out to the gap portion 120. That is, the liquid coating material may be restricted from flowing to the gap 120 shielded by the protrusion 115.

4 is a flow chart showing a method of manufacturing a cooking device according to an embodiment of the present invention. A method of manufacturing the cooking apparatus according to the present embodiment will be described with reference to Fig.

The bottom portion 110 and the side portion 130 are assembled so that the protrusion 115 shields the gap portion 120. [ That is, the inner surface of the lower end of the side body 131 is positioned on the outer side of the protrusion 115 in the process of assembling the lower surface 110 and the side surface 130 (S12).

The protrusion 115 shields the gap 120 between the lower surface 110 and the side surface 130 when the lower surface 110 and the side surface 130 are assembled.

Then, welding is performed to the joint between the protrusion 115 and the side body 131 (S13). By welding, the bottom portion 110 and the side portion 130 can be firmly coupled (S13).

As a finishing process for manufacturing the cavity 100, a painting process using a predetermined paint is performed on the inner surface of the lower surface portion 110 including the welding portion and the side surface portion 130. In the process of coating, the liquid paint may be blocked by the protrusion 115 and flow into the gap 120 (S14).
