FIG. 1 is a plan view showing the inside surface of the door of the cooking device according to the first embodiment of the present invention. FIG. 2 is a sectional view of a main part showing a door of the cooking device according to the first embodiment of the present invention.

In the cooking device according to the present embodiment, a small hole 2a is provided on the bonding surface of the concave portion 2c of the door body 2 into which the silicone adhesive 11 is poured. This small hole 2a
The number and size (outer diameter) are determined according to the adhesive strength. That is, when increasing the adhesive strength, the number is increased and / or the size is increased. The small hole 2a may be subjected to burring.

When the silicon adhesive 11 is poured into the gap between the door body 2 and the glass plate 6, the surface height of the silicon adhesive 11 does not become higher than the surface height of the door body 2 and the surface height of the glass plate 6. To be filled. At this time,
The silicone adhesive 11 is provided in the recess 2 c of the door body 2.
, And overflows the outside of the door body 2 (opposite to the adhesive surface). Since the silicon adhesive 11 has viscosity, it is not dropped.

For this reason, the silicone adhesive 11 is fixed in a raised state around the small hole 2 a outside the door body 2. Also, since the silicon adhesive 11 is filled in the small holes 2a, the bonding strength is increased. That is, when the glass plate 6 is to be removed, the portion of the silicone adhesive 11 outside the door body 2 and the portion inside the small hole 2a are hardly detached by being caught by the small hole 2a, and the bonding strength is increased.

As described above, in the cooking device according to the present embodiment, the surface height of the silicone adhesive 11 is lower than the height of the surface of the cooking device body of the door body 2 and the surface of the glass plate 6.
