Description

  The present invention relates to a cooking device.

  Conventionally, as a cooking device, a casing having a heating chamber that opens forward, a slide portion that slides in the front-rear direction with respect to the casing, and a slide portion that is attached to the slide portion so as to be positioned in front of the casing, There is a thing provided with the door part which opens and closes (refer to JP, 2007-80762, A: patent documents 1).

  In recent years, an increasing number of cooking is performed by taking steam into the heating chamber, and a sealing member such as packing is disposed between the door portion and the periphery of the heating chamber opening of the casing.

  Here, in the general structure of the drawer-type door, the slide part is disposed at the lower part of the casing, and the door part is attached to the slide part at the lower part. The retraction of the door generally works at the height of the slide portion. For this reason, when the door part is closed, the closing force of the door part is weak at the upper part of the door part and strong at the lower part of the door part.

  As a result, there has been a problem that the steam generated in the heating chamber leaks due to the upper portion of the door being opened due to an increase in the pressure of the steam in the heating chamber or bumping of the object to be cooked.

  Therefore, in order to prevent vapor leakage from the upper part of the door part, it is conceivable to attach the door part to the slide part so that the upper part of the door part is inclined toward the opening side of the heating chamber, but the door part is closed. Sometimes, a gap is formed between the lower portion of the door portion and the periphery of the opening of the casing, and the steam leaks from the gap.

  In general, the mounting part between the door part and the sliding part has a design play due to the tolerance of the door part and the sliding part, the mounting play to the sliding part of the door part, and the accuracy of the parts of the door part and the sliding part. There is a backlash. For this reason, when the door portion is closed, a gap is formed between the door portion and the periphery of the opening of the casing, and steam leaks from the gap.

  As described above, in the conventional cooking device, when the door portion is closed, a gap is formed between the periphery of the heating chamber opening of the casing and the door portion, or the pressure of steam in the heating chamber is increased or covered. Since the door portion is opened due to bumping of the food to be cooked, there is a problem that steam generated in the heating chamber leaks when the food is cooked in the heating chamber.
