Abstract
An oven includes an oven liner partially defining a cooking cavity having a bottom wall. The oven liner has a bottom wall which together with a glass-ceramic panel forms the bottom wall of the cooking cavity. The bottom wall of the oven liner has a bowl-shaped depression forming bottom and lateral sides of a chamber. The glass-ceramic panel covers the depression and defines a top wall of the chamber. The bottom wall of the oven liner forms a recessed seat for the glass-ceramic panel around a periphery of the depression such that a top surface of the bottom wall of the cooking cavity is smooth. A periphery of the glass-ceramic panel is sealed with a high temperature sealant to prevent leakage of spills from the cooking cavity to the chamber. A heating element is provided within the chamber to heat the cooking cavity. In an alternative embodiment, the oven includes a tray received within an enlarged bottom portion of the oven liner and supported by the bottom wall of the oven liner. The tray together with the glass-ceramic panel forms the bottom wall of the cooking cavity and forms the bowl-shaped depression and recessed seat.
Description
2 1 8~498 I
3The present invention generally relates to an oven, 4 and more specifically, to an oven having a cooking cavity with a smooth bottom.
7 Standard porcelain enamel cooktop surfaces of 8 domestic ranges with separate electrical heating elements 9 or gas burners have, in some appliances, been replaced with smooth top cooking surfaces in order to improve the 11 cleanability of the cooktops. The smooth top cooking 12 surfaces typically include an opaque glass-ceramic plate 13 which directly supports cooking utensils and is heated by 14 electricity or gas to conduct heat to the cooking utensils. The smooth top cooking surfaces are of an 16 almost ground glass finish or texture which presents a 17 pleasing appearance and is also readily cleanable. The 18 smooth top cooking surfaces also provide a continuous 19 surface which prevents drainage of spill overs underneath the cooktop.
21 Ovens of domestic ranges, however, are relatively 22 difficult to clean. The ovens typically have a cooking 23 cavity supplied with two electric heating elements or 24 burners, a baking element is positioned adjacent a bottom wall of the cavity and a broiling element is positioned 26 adjacent a top wall of the cavity. The baking element is 27 typically positioned about two inches above the bottom of 28 the cooking cavity. Spill overs within the oven, 29 ~therefore, are difficult to clean because the baking element impedes the cleaning of the bottom wall.
31 Accordingly, there is a need in the art for an oven 32 having improved cleanability.
.: .- . ' ' . .-- 2 ~ 83498 1 The present invention provides an oven which 2 overcomes at least some of the problems of the related 3 art. The oven includes an oven liner partially defining 4 a cooking cavity and a glass-ceramic panel at least partially forming a bottom wall of the cooking cavity.
6 The bottom wall of the cooking cavity has a recessed seat 7 for the glass-ceramic panel such that a top surface of 8 the bottom wall of the cooking cavity is generally g smooth. The oven also includes a chamber within said oven liner and contiguous with the cooking cavity. The 11 glass-ceramic panel at least partially defines a top wall 12 of the chamber. A heating element is provided within the 13 chamber for heating the cooking cavity. Preferably, a 14 periphery of the glass-ceramic panel is sealed with a high temperature sealant to prevent leakage of spills 16 from the cooking cavity to the chamber. The oven, 17 therefore, has a cooking cavity with a generally smooth 18 and conti~uous bottom surface which improves 19 cleanability, has an uncluttered appearance of a clean efficient oven cavity, and increases the effective 21 capacity of the oven without increasing the size of the 22 oven cavity.
24 These and further features of the present invention will be apparent with reference to the following 26 description and drawings, wherein:
