Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
An electric fryer comprising a cooking chamber having an open top; and electric heating element associated with said cooking chamber, said heating element being operatively connected to an electric circuit whereby said cooking chamber can be heated; a filtering lid adapted to fit on said cooking chamber so as to close said open top provided with an external annulus, said filtering lid comprising a lower condensation wall and an upper condensation wall defining therebetween a condensation chamber; a reflector situated between said lower condensation wall and said cooking chamber; means providing communication between the cooking chamber and the condensation chamber; filter means carried by the upper condensation wall providing communication between the condensation chamber and the exterior of said filtering lid; and means for discharging towards the exterior of said filtering lid water of condensation collected in the condensation chamber.
Claim 2
Dependent Claim
140 words
An electric fryer comprising a cooking chamber having an open top; and electric heating element associated with said cooking chamber, said heating element being operatively connected to an electric circuit whereby said cooking chamber can be heated; a filtering lid adapted to fit on said cooking chamber so as to close said open top provided with an external annulus, said filtering lid comprising a lower condensation wall and an upper condensation wall defining therebetween a condensation chamber; a reflector situated between said lower condensation wall and said cooking chamber; means providing communication between the cooking chamber and the condensation chamber; filter means carried by the upper condensation wall providing communication between the condensation chamber and the exterior of said filtering lid; and means for discharging towards the exterior of said filtering lid water of condensation collected in the condensation chamber.
Claim 3
Dependent Claim
83 words
An electric fryer according to claim 1, in which the reflector consists of a sheet of bright aluminium fixed to the lower face of the lower condensation wall, the lower condensation wall is integral with the inner wall of said external annulus, the upper condensation wall bears on an internal shoulder of said inner wall and on studs integral with the lower condensation wall, the latter also comprising sleeves for receiving screws for fixing the upper condensation wall to the lower condensation wall.
Claim 4
Dependent Claim
57 words
An electric fryer according to claim 1 in which the filter means comprise a filtering assembly including an activated carbon filter associated with an anti-grease filter situated upstream of the activated carbon filter, the filtering assembly being spaced from the upper condensation wall by ribs and the two filters being held in place by a detachable grid.
Claim 5
Dependent Claim
128 words
An electric fryer according to claim 1 in which a handle is provided with a duct openable towards the exterior and so arranged that when the filtering lid is raised the water of condensation which has collected in the condensation chamber flows into a tank fixed on the exterior of the fryer, and further, in which a compressible sealing element is arranged below the lower orifice of the duct in such a manner that when the filtering lid is in its horizontal closed position, the lower orifice of the duct penetrates slightly into the sealing element, thus ensuring the sealing-tightness of the duct during cooking, whereas during the opening of the filtering lid the water of condensation flows to the duct and through the latter into the tank.
Claim 6
Dependent Claim
117 words
An electric fryer according to claim 1 in which "a window mounted rotatably in the filtering lid is provided with a scraper," the window comprising an upper shell and a lower shell which are mounted to be rotatable in sealing-tight manner in a compartment, the lower portion of the window extending through not only the lower condensation wall, but also the reflector, in such a manner that the lower surface of the lower shell is situated in the cooking chamber, and a support integral with the filtering lid is provided at the lower portion of the filtering assembly, the support comprising a scraper whose upper portion is in permanent contact with the surface of the lower shell.
Claim 7
Dependent Claim
62 words
An electric fryer according to claim 1, in which the communication means between the cooking chamber and the condensation chamber comprises a group of vents in said lower condensation wall and said reflector, and in which the communication means between the condensation chamber and the filter means comprises a series of orifices formed in the upper condensation wall below the filtering assembly.
Claim 8
Dependent Claim
41 words
An electric fryer according to claim 6 in which said orifices are located in a section of said upper condensation wall which is opposite to the section of said lower condensation wall and said reflector in which said vents are located.
Claim 9
Dependent Claim
38 words
An electric fryer according to claim 7 in which said vents are in an order of decreasing diameter starting at a point most distant from said section of said upper condensation wall in which said orifices are located.
