The present invention relates to a heating cooker comprising a top plate comprising a glass plate and a frame portion attached to an edge portion of the glass plate, and a case member in which a detection means for detecting a predetermined operation by an operator is accommodated through the glass plate.

Conventionally, a gas furnace is known as such a heating cooker, and it is common to operate the gas burner accommodated in the furnace main body by installing the operation part in the front of a main furnace main body (refer patent document 1). In the gas stove, since the operation part is installed in the front of the main body of the furnace, the heat is not affected by the burner. However, in the case of the drop-in type furnace, there is a problem in that operability is poor because the operation part is located under the countertop. there was.

So, for example, as shown in FIG. 19 and FIG. 20, the gas furnace which provided the operation part in the upper board is proposed (refer patent document 2). In the gas stove, the main body case 61 is formed in a box shape having an upper surface open, and is suspended in the attachment hole 62a formed in the kitchen counter 62 by the flange portion 61a formed on the outer periphery of the upper end. It is fitted in shape to be supported. An upper plate 63 is attached to the upper surface opening of the main body case 61, and a pair of burner openings 63a are formed on the upper surface thereof, and a pair of operation shaft through holes 63b for the operation portion are provided in the front. Formed. In the main body case 61, a pair of gas burners 64 are provided corresponding to the burner opening 63a. Moreover, the trivet 65 is attached to the periphery of the opening part 63a for both burners.
