First, since a blowing fan, a display, a control device, and a duct, which are previously installed in the upper part of the cabinet, are all accommodated in the door side, unnecessary space for accommodating the above components in the upper part of the cabinet can be removed as in the related art. In addition, the cavity can be extended to the space to be used as a cooking space, and as a result, in a cooking apparatus having the same volume, a larger cavity volume can be secured.

Second, since the blower fan is located close to the place where the air is sucked, unlike the prior art, the flow passage of the air constituting the cooling system can be configured to be shorter than the conventional one, so that the air volume and the wind speed of the air flowing through the cooling passage is greater, Cooling can be made more efficient.

Third, since the discharge direction of the air discharged after the cooling of the door and the cavity ventilation is adjusted upward by the guide, it is conventionally discharged to the front of the cabinet to solve the problem of directly injecting hot heat, smoke, smell, etc. into the user's face. That is, a factor causing discomfort to the user is eliminated, and convenience in using the cooking appliance is increased.
