Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
In an electrical hot-air grill of a type comprising a chassis, a grilling compartment supported on the chassis and bounded by an upper shell and a lower shell, which may be separated from each other to open the grilling compartment, a blowing and heating apparatus mounted on the chassis and arranged to blow hot air into the grilling compartment, an improvement wherein the upper shell is supported removably on a frame, which is mounted pivotally to the chassis, so as to be removable from the frame without it being necessary to release a fastening element and so as to be pivotable up and down about a transverse axis, which is located so as to provide that the grilling compartment is opened when the upper shell thus is pivoted up and closed when the upper shell thus is pivoted down and that condensate dripping from the inner side of the upper shell tends to drip mostly into the lower shell but not onto outer portions of the electrical hot-air grill when the grilling compartment is opened.
Claim 2
Dependent Claim
175 words

Claim 3
Dependent Claim
17 words
The improvement of claim 1 wherein the frame extends substantially horizontally when the grilling compartment is closed.
Claim 4
Dependent Claim
28 words
The improvement of claim 2 wherein the frame is mounted pivotally to the chassis substantially on a level not lower than the uppermost portions of the upper shell.
Claim 5
Dependent Claim
46 words
The improvement of claim 2 or 3 wherein a gasket is supported on the frame so as to separate the upper shell and the lower shell when the grilling compartment is closed and wherein the upper shell rests on and may be lifted off the gasket.
Claim 6
Dependent Claim
24 words
The improvement of claim 4 wherein the gasket has a face that is inclined so as to center the upper shell within the gasket.
Claim 7
Dependent Claim
77 words
The improvement of claim 2 or 3 wherein the lower shell rests on the chassis and may be lifted off the chassis when the grilling compartment is opened, and wherein the lower shell comprises at least one cam, which fits into a recess in the chassis so as to locate the lower shell when the lower shell rests on the chassis and which is shaped as a ladle so as to receive juices in the lower shell.
Claim 8
Dependent Claim
51 words
The improvement of claim 2 or 3 wherein an apertured plate is mounted on the blowing and heating apparatus and arranged between the blowing and heating apparatus and the grilling compartment so as to be removable from the blowing and heating apparatus without it being necessary to release a fastening element.
