Patent ID: 8424449

Claim:
A lifting-cover frying-roasting device comprising: a bottom base which has an open top, the bottom base including bosses extending backwards at two sides of a back end of the bottom base, r-shaped orbits having openings that are formed at back ends of the bosses, the r-shaped orbits extending towards front lower parts of the bosses, the r-shaped orbits each being set inside of one of the bosses, the r-shaped orbits each being curved, blocking walls that extend from the boss back ends to the inside of each boss, a height of the blocking walls being lower than a height of the openings of the r-shaped orbits, and a joint deck at a front end of the bottom base; an electric heating frying-roasting plate disposed on said open top, the electric heating frying-roasting plate including a plate body; an upper cover covering the electric heating frying-roasting plate, said upper cover having a curved shape extending from a first side of the upper cover to a second side opposite the first side of the upper cover, the upper cover including two jointed shafts being inserted in the r-shaped orbits to form a disengageble hinging connection, the upper cover being movable to be lifted to form the hinging connection, a buckle set at a front of said upper cover, said buckle being engageable with the joint deck for clamping said upper cover to the bottom base, a back connecting member made of plastic, the two jointed shafts extending outward from two sides of a back end of the back connecting member, a front connecting member made of plastic, a joint set at a front of the front connecting member; and a glass panel, fastened between a front end of the back connecting member and a back end of the front connecting member, wherein each of the two jointed shafts is adapted to slide downward along a respective one of the r-shaped orbits to reach a bottom-most portion of the respective r-shaped orbit, and further wherein a bottom surface of the back connecting member is blocked by a back surface of the plate body while a top surface of the back connecting member is blocked by the blocking walls thereby allowing the upper cover to be sloped when the frying-roasting device is in an open position.
