Abstract
Abstract A wall-mounted type cooking apparatus of the present invention is mounted over a range in a kitchen and comprises a fixing plate mounted on a wall and a body fixed on said fixing plate and serving not only as a cooking apparatus but also as a ventilating apparatus for air nearby the range. A body of the apparatus of the present invention is fixed on the fixing plate by engaging ridge-like shape engaging members formed by making a gap between the rear end of a bottom plate of the body and the lower end of a back plate with supporting members formed laterally on the fixing plate. The fixing plate is provided with locking members for inserting locking bars respectively thereinto in the upper portion thereof. The back plate is provided with an opening for projecting the locking members and the locking bars moving up and downwardly therethrough. The body is fixed on the fixing plate by forwardly projecting the locking member through the opening of the back plate and inserting the locking bar into the locking member. Furthermore, since the front edge of the supporting member is cut off at the position corresponding to that of the spacer making the gap between the bottom plate of the body and the back plate, the spacer is put in the cut off portion when the engaging member of the body was engaged with the supporting member of the fixing plate, whereby the body is automatically positioned.
