In the former one of the ones described in the above publication, the stove main body is attached to the top plate engaged with the cooktop top plate, so that a large load acts on the top plate. Therefore, it is necessary to make the top plate strongly, and there is a limit in reducing the amount of protrusion of the top plate from the cooking top plate.

Further, among those described in the above publication,
In the latter one, there is a problem in that dust and boiled spills accumulate on the carved top surface of the cooking table top, and the aesthetic appearance is significantly impaired as it is used.

In view of the above problems, it is an object of the present invention to provide a drop-in stove in which the top plate does not need to be made stronger than necessary and the aesthetic appearance is not impaired as it is used. To do.

[0009]

In order to solve the above-mentioned problems, a drop-in stove according to the present invention comprises a top plate and a stove body, and a cooktop inserted in an attachment hole formed in the cooktop top plate. In a drop-in stove attached to a top plate, a protrusion projecting inward from the upper opening edge of the mounting hole is provided in the attachment hole, and the top plate is engaged with the upper surface of the cooktop top and the stove body is protruded. It is characterized by being held in.

According to the above construction, all the load of the stove body acts on the projecting portion, and the load of the stove body does not act on the top plate. Therefore, the top plate can be made thin,
It is possible to reduce the amount of protrusion of the top plate from the upper surface of the cooking top plate.

Further, the stove body is provided with a cylindrical wall portion which is in contact with the lower surface of the top plate over the entire circumference in a state where the top plate is engaged with the upper surface of the cooktop, and the hot air of the burner is transmitted along the lower surface of the top plate. If the cylindrical wall portion is configured to prevent the above-mentioned action on the cooking table top plate, the cooking table top plate is less likely to be heated during cooking.

Further, the top plate has a flange portion which engages with the upper surface of the cooking table top plate at the upper end, and has a bottom plate portion located below the flange portion, and Gotoku is placed on the upper surface of the bottom plate portion. If it is configured so that it can be placed, the height of Gotoku will be lowered, and the height of cooking utensils such as a pot during cooking can be lowered.

By the way, a controller section for adjusting heat power and a point extinguishing operation may be attached to the cooktop top plate, and communication may be made between the stove body and the controller section.
