In addition, a plurality of mounting holes 24 and bosses 25 are formed on the front frame front bottom surface portion 22e. Furthermore, as shown in FIGS. 4 and 6 , the front frame front bottom portion 22 e has a substantially trapezoidal covering portion 26 protruding inwardly of the top plate unit 1 in the vicinity of the lateral ends.

The front frame side bottom portion 22f and the front frame front bottom portion 22e formed by bending toward the top plate 11 side at the lower end portion of the front frame side portion 22d are formed in substantially the same plane, and at the corner portion 19 of the protective frame 12 Adjacent nearby. Moreover, the cover part 26 which protrudes inwardly of the top plate 11 is formed in the edge part of the front frame front bottom surface part 22e. In this embodiment, the cover part 26 is formed in the vicinity of both ends of the front frame front bottom surface 22e, and is formed in the vicinity of the end of the front frame side bottom surface 22f. That is, the width of the front frame side bottom portion 22f may be made larger than the width of the front frame front bottom portion 22e. In addition, the shape of the cover part 26 is not limited to the shape shown in FIG. Any shape may be used in which the adjacent portions of the front frame side bottom portions 22f are larger than those without the covering portion 26 .

In addition, as shown in FIGS. 3 and 4 , on the outer surface of the side frame 21b, the protruding portion 29 protruding outward in a band shape as described above extends along the rear ends 22h and 22i of the front frame 22 . It is provided on the outer surface of the side frame 21b in the vicinity of the front side end 21i in such a manner. The protrusions 29 are formed along the outer surfaces in the vicinity of the front end portions 21i of the left and right side frames 21b, respectively. The convex part 29 is formed by deforming the cross-sectional shape into a shape such as a part of an approximately ellipse or a part of a substantially rectangular shape. In addition, the protruding amount of the convex portion 29 may also be determined according to the plate thickness of the front frame 22 and the degree of looseness, which refers to the gap for fitting the front frame 22 and the frame 21 .

In addition, as shown in FIGS. 7 and 8 , the cross section of the front frame 22 is formed in a substantially U-shaped shape, and the front frame 22 is attached along the front edge of the top plate 11 . At this time, the end portion 21i of the side frame 21b is inserted into the inside of the front frame side portion 22d and the front frame top portion 22a, and the rear end portion 22h of the front frame side portion 22d and the front frame top portion 22a is in contact with the side frame 21b.

It is bent downward and inclined, and the end of the edge 30 is in contact with the surface of the top plate 11 (the surface on which the cooking container is placed). Thereby, the gap formed between the top plate 11 and the front frame top surface part 22a can be closed. As a result, entry of dust and the like into the formed gap can be prevented.

In this way, the protective frame 12 omits the joint parts formed by other parts at the connecting portion of the side frame 21b and the front frame 22, reduces the number of parts constituting the protective frame 12, and is easy to assemble. In addition, the rear end portions 22i and 22h of the front frame 22 are disposed near the convex portion 29 formed on the upper surface and the side surface of the side frame 21b, and the front end portion 21i of the side frame 21b is covered by the front frame 22, whereby It is possible to prevent a cook from being injured by touching the end of the front frame 22 or the end 21i of the side frame 21b. In addition, since the front frame 22 constituting the protective frame 12 forms corners perpendicular to the inner linear ends of the side frames 21b, the exposed corners of the top plate 11 bordered by the protective frame 12 can be substantially at right angles. Thereby, the aesthetics of the top plate 11 can be improved.

Next, the protection covers 15a and 15b placed on the top plate 11 will be described with reference to FIGS. 1 , 2 , 12 , 13 and 14 .
