Description

  The present invention relates to a built-in cooking device incorporated in a kitchen counter of a general household.

Conventionally, in this type of built-in heating cooker, the plate constituting the cooking surface is fixed to the lower surface of the metal top frame with an adhesive, and this top frame is fixed to the outer case and screws that cover the built-in parts. By fixing, what equips an outer case with a plate is proposed (for example, refer patent document 1).
JP 2006-200247 A

  However, in the conventional configuration, since the plate is only bonded to the lower surface of the top frame, there is a concern about the reliability of the adhesive strength between the plate and the top frame when a load is applied to the plate by a pan or food. Is. In the unlikely event that there is a lack of adhesion, if a large load is applied to the plate, the plate may fall off the top frame and touch the built-in heating device or charging part.

  In order to prevent this, it is conceivable to provide a sheet metal under frame below the plate and hold the plate by sandwiching it between the top frame and the under frame. In such cases, it is difficult to secure a space for forming the underframe, and even if it can be configured, there is a problem of practical use due to large parts cost and mold cost.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a built-in heating cooker that does not drop off a plate, is inexpensive, is easy to use, and is excellent in cleanability and safety.

  In order to solve the above-described conventional problems, the built-in heating cooker of the present invention includes an outer case that covers a built-in component, and a top frame unit that covers an upper surface opening of the outer case and is integrated with the outer case. The top frame unit is composed of a plate constituting the cooking surface and a top frame that covers the outer periphery of the plate and is fixed to the plate with an adhesive, and the outer case is a flange that supports the outer peripheral lower surface of the plate opposite to the top frame. A part is provided.

  As a result, the load applied to the plate during cooking, such as a pot and food, is supported mainly by the flange portion of the outer case, and there is no problem of adhesive strength, and the plate does not fall off. In addition, since the flange portion of the outer case is used, it is inexpensive, easy to use, and excellent in cleanability and safety.
