However, with the above configuration, although the inconvenience of scratches on the top plate can be prevented by the trivet, no measures have been taken to prevent scratches on the burner ring.
In particular, the cast-made trivet, which has a trivet frame with a rectangular frame that is installed so as to cover the entire top plate, is large, hard, heavy, and has a rough surface. If the convex part or its surrounding area hits or rubs against the burner ring when fitting it into the concave part of the burner ring, or if the pot or frying pan placed on the trivet claw is violently moved during use, it is strong against the trivet. There is an inconvenience that the burner ring is scratched when the convex part of the trivet is rattled in the concave part of the burner ring by applying an impact. In particular, in the case of burner ring made of aluminum material, if the burner ring is noticeably scratched or peeled off due to the impact of the trivet, there is a problem that the appearance of the entire gas stove is spoiled.

The present invention has been made in view of the above problems, and when the trivet is placed in a positioned state around the annular burner ring provided on the periphery of the burner opening of the top plate, or during cooking, the trivet claw is used. Even if the trivet hits, rubs, or rattles the burner ring when the pot, etc. placed on the stove is shaken to give a shock to the trivet, the burner ring may be scratched. The object is to maintain the aesthetic appearance of the gas stove by preventing the inconvenience of the paint peeling off.

The present invention relates to a gas stove in which an annular burner ring is provided on the periphery of a burner opening provided on a top plate, and a trivet is installed in a positioned state with respect to the burner ring.
The trivet has a trivet frame installed along the outer peripheral edge of the burner ring and a plurality of trivet claws provided on the trivet frame.
At least one engaging portion for positioning is provided on the outer peripheral edge of the burner ring, and at least one engaged portion capable of engaging with the engaging portion is provided on the inner peripheral edge of the trivet frame.
A cushioning member is provided on at least one of the engaged portion and the engaged portion.

The above means operate as follows.
The top plate is provided with an opening for a burner and an annular burner ring on the peripheral edge thereof, and a positioning engaging portion provided on the outer peripheral edge of the burner ring is provided on the inner peripheral edge of the trivet frame of the trivet. By engaging the engaged portion of the trivet, the trivet is placed on the top plate in a positioned state around the burner ring. At this time, even if the engaged portion provided in the trivet frame cannot be successfully engaged with the engaged portion provided in the burner ring at one time, at least either the engaged portion or the engaged portion. The cushioning member provided on one side first hits the front surface of the burner ring or the back surface of the trivet frame, so that the back surface including the engaged portion of the trivet frame directly hits or rubs against the front surface of the burner ring. It can be relaxed.

In the gas stove, preferably, the engaging portion is a concave portion or a convex portion formed on the outer peripheral edge of the burner ring.
The engaged portion is a convex portion or concave portion formed on the inner peripheral edge of the trivet frame and can be fitted to the concave portion or convex portion.

Since the trivet has a rectangular frame that is installed so as to surround the rectangular top plate and an arc-shaped frame that is positioned by the burner ring, the size of the entire trivet is large. Weight increases on top. In such a large and heavy trivet, it is difficult to fit the convex portion provided at at least one end of the arcuate frame into the positioning concave portion provided in the burner ring at one time, but at least convex. Since a cushioning member is provided on the back surface of the portion, the cushioning member comes into contact with the surface around the concave portion of the burner ring first, which prevents inconveniences such as scratches on the burner ring and peeling of the paint. You can. Further, if the cushioning member is provided over the entire inner peripheral edge of the arc-shaped frame including the convex portion, there is an inconvenience that the burner ring is damaged no matter which part of the inner peripheral edge of the arc-shaped frame is rubbed against the burner ring. It can be prevented.

In the gas stove, the trivet is preferably made of casting.
Since the cast trivet is hard and the surface remains rough, it is easy to get scratches when it hits or rubs against the burner ring, but the cushioning member hits the burner ring first, and the surface of the cast trivet is burnered. Since it is difficult to directly touch the burner, even the cast-made trivet can surely prevent the burner ring from being damaged.
