In the trivet 1, each of the cover 4 and the plurality of claws 5 is made of, for example, stainless steel. The cover 4 and the plurality of claw portions 5 are joined by welding, for example. The cover 4 and the plurality of claws 5 may be integrally molded by casting or the like.

(2-2) Top plate The top plate 2 is formed of, for example, tempered glass having heat resistance. As shown in FIG. 1, the upper surface of the top plate 2 is a flat surface. A through hole 20 through which the gas burner 3 is inserted penetrates the top plate 2 in the vertical direction. The through hole 20 is a circular hole.

(2-3) Gas Burner The gas burner 3 includes a burner main body 30 and a burner cap 31 mounted on the burner main body 30. The burner cap 31 is removable from the burner body 30. A plurality of flames arranged in an annular shape are formed on the outside (outward diameter direction) of the boundary portion between the burner main body 30 and the burner cap 31.

The burner main body 30 has a substantially cylindrical insertion portion 32 and a mixing tube portion (not shown) protruding outward from a part of the lower portion of the insertion portion 32 in the circumferential direction. The insertion portion 32 is a portion that is inserted through the through hole 20 and projects upward from the top plate 2.

(4) Action and Effect In the trivet 1 of the present embodiment described above, since the plurality of claw portions 5 project outward from the cover 4 and the entire upper surface 41 of the cover 4 is flat, the upper surface 41 of the cover 4 is a rag. Easy to wipe and clean.

Further, in the trivet 1 of the present embodiment, since the cover 4 covering the gap S1 between the gas burner 3 and the top plate 2 from above is continuous with the plurality of claw portions 5, they are provided separately and fitted to each other. Compared to the case, the number of parts can be reduced and the infiltration of the broth into the boundary between the parts can be prevented.

Further, in the trivet 1 of the present embodiment, since the upper surface 41 and the lower surface 42 of the cover 4 are both flat surfaces, both the upper surface 41 and the lower surface 42 can be easily wiped and cleaned.

Further, in the Gotoku 1 of the present embodiment, since the upper surface 41 of the cover 4 and the upper surface 53 of the lower piece portions 50 of each of the plurality of claw portions 5 are flush with each other, the upper surface 41 of the cover 4 and each lower surface 41 are flush with each other. The upper surface 53 of the piece 50 can be wiped and cleaned smoothly. In addition, when it is continuous through the step, it is difficult to remove the dirt adhering to the step.

Further, in the trivet 1 of the present embodiment, the lower surface 54 of each lower piece portion 50 of the plurality of claw portions 5 also has two surfaces having different heights (first surface 54a and second surface 54b) continuous without a step. Therefore, it is easy to wipe and clean. Further, in the trivet 1 of the present embodiment, the lower second surface 54b is located on the outer side of the lower surface 54, so that rattling in the state where the trivet 1 is placed on the top plate 2 is suppressed.

Further, in the Gotoku 1 of the present embodiment, the lower piece portion 50, the side piece portion 51, and the upper piece portion 52 of each of the plurality of claw portions 5 are smoothly continuous with each other on their surfaces. Easy to wipe and clean.

Further, in the gas stove 100 of the present embodiment, since the outer peripheral surface of the gas burner 3 includes a concave curved surface 33 that is continuous with the upper surface 41 of the cover 4 without a step, the broth received by the concave curved surface 33 is received by the upper surface of the cover 4. It is easy to let the 41 flow and drop it to the outside of the cover 4, and it is possible to prevent the broth from entering between the gas burner 3 and the cover 4.

Further, in the gas stove 100 of the present embodiment, since the cover 4 is located at a distance from the ring member 6, the heat of the gas burner 3 is difficult to be transferred to the ring member 6, and the broth sticks to the ring member 6. It can be suppressed.

(5) Modification Example Next, a modification of the Gotoku 1 and the gas stove 100 of the above-described embodiment will be described.

The plan view shape of the cover 4 is not limited to an annular shape, but may be an annular shape of any other shape, and the shapes of the inner peripheral surface and the outer peripheral surface 40 may be different from each other.

Further, in each of the plurality of claw portions 5, the lower surface 54 of the lower piece portion 50 may be located flush with the lower surface 42 of the cover 4.

In each of the plurality of claw portions 5, the lower surface 54 of the lower piece portion 50 may be a flat surface having a constant height, or a cushioning member such as rubber packing is attached to the outer end portion of the lower surface 54. The other parts of the lower surface 54 may be continuous surfaces without steps.

The gas burner 3 and the trivet 1 may be provided so that the upper surface 41 of the cover 4 is located below the concave curved surface 33 of the gas burner 3.

The gas stove 100 may not be provided with the ring member 6, and the gap S1 formed between the gas burner 3 and the top plate 2 may be covered from above with only the cover 4.
