Abstract:
A turntable heating apparatus, using a jet impingement operation, comprising:generating means for generating heated air, said generating means being positioned in a rear side of a heating chamber;wall surfaces of the heating chamber, said wall surfaces also being used as a part of an air supply path for guiding the heated air from said generating means to a front side of the heating chamber;a jet plate for changing the heated air into a jet of the heated air by utilizing a plurality of jet ejectors;a support axle positioned inside said wall surfaces of the heating chamber;a turntable, supported by said support axle inside said wall surfaces of the heating chamber, so that the turntable is rotated around said support axle;a driving source, positioned at an upper side of the heating chamber, for generating a rotating torque; anda driving means for transmitting the rotating torque generated by said driving source to said turntable;at least said support axle, said turntable, said driving means, and said jet plate being removable from the heating chamber;wherein at least one part of a top surface and one part of a bottom surface of said wall surfaces of the heating chamber are each provided with a scarfed area of which a cross section becomes more tapered in a direction from the rear side to the front side of said heating chamber, so that said heated air can be guided along each said scarfed area and cleaning water can be stored in a recess formed by said scarfed area of the bottom surface; andwherein cleaning of the inside of the heating apparatus is improved by enabling said support axle, said turntable, said driving means, and said jet plate to be removed from the heating chamber and the cleaning water stored in said recess to be changeable into vapor by said generating means.
