Definitions
- the present invention refers to a cooking oven, in particular of the kind intended for use in association with household-type cookers, featuring an innovatory design concept in view of doing away with all problems encountered in the use of such appliances owing to condensate forming during the operation of the oven.
- Cooking ovens that are adapted to carry out both traditional and forced-convection, i.e. fan-assisted cooking processes are known since quite a long time now.
- ovens are usually made of a sheet-metal material and comprise a muffle, or cooking cavity, inside and outside which there are arranged a number of functional component parts, such as electric heating elements, insulation materials, lighting lamps, fans, sealing gaskets, and the like.
- the front access or loading aperture of such ovens is adapted to be tightly closed by a door, which is generally is a glazed door provided with an outside handle and sealing gaskets arranged all along the peripheral edges thereof, and hinged on to the lower edge of said front aperture of the cooking cavity.
- a major drawback that is generally encountered in such cooking ovens during the operation thereof is brought about by the generation of hot vapours which, by condensing on to the cold surfaces, in particular the glass panes of the door, give rise to misting effects, which prevent the interior of the cooking cavity from being properly viewed from the outside, as well as to the formation of water which, when the oven door is opened, can disadvantageously drip both inside and outside the same oven.
- real risky situations for the user can be triggered when, upon opening the oven door, a relatively large amount of steam at a rather high temperature is suddenly discharged outside.
- US 2,375,047 discloses an oven comprising a partition 26 disposed within the oven; such partition 26 provides with the top wall of the oven liner a chamber 32 which extends over a substantially portion of the top of the oven.
- the partition 26 is provided with one or more inlet openings 33, 34, which permit the hot gases and vapours within the oven to enter the chamber 32, the latter being connected to the atmosphere. Due to the close proximity of the upper heating element 15 and due to the fact that the chamber is disposed at a hot part of the oven, the vapours entering the chamber are dried and the cooking odors are burned out. Thus, the chamber has the effect of superheating the vapours, permitting them to be discharged into the atmosphere without condensing on the outer surface of the range around the vent opening.
- a cooking oven comprising a muffle, or cooking cavity, which is provided with a front door for tightly closing it, characterized in that a sealed hollow jacket is applied on to the outer surface of at least a wall of said muffle or cooking cavity of the oven, and said hollow jacket is in a communicating relationship with the interior of the cooking cavity via at least two apertures provided in said wall, and spaced from each other, in such a manner as to bring about a closed-loop circulation of vapour between said jacket and said cooking cavity.
- a cooking oven according to the present invention substantially comprises a muffle 10, which is generally made of enamel-coated sheet-metal, and which defines a cavity whose front aperture is closed by a door 11.
- the upper wall of said muffle or cooking cavity 10 is provided with two apertures 12 and 13 ( Figure 2), which arranged spaced, i.e. at a distance from each other and, preferably, in mutually opposed positions with respect to a central plane of the oven muffle.
- These apertures enable the interior of the muffle to communicate with an outer hollow jacket 14 that substantially covers the whole surface of the wall.
- the temperature of the vapour decreases, but not to such an extent at to cause it to condensate.
- the inner wall of the hollow jacket 14 is formed by the corresponding wall of the cooking cavity 10, so that it is quite hot.
- the hollow jacket 14 may be applied on to any wall of the oven muffle, but is preferably associated to the upper wall thereof. Furthermore, the hollow jacket may be made in any of a number of different forms, i.e. in a curved form (Figure 3A), in the form of rectilinear segments (Figure 3B), in a box-like form (Figure 3C), in the form of a double superposed chamber (Figure 3D), or in the form of a curvilinear conduit (Figure 3E).
