Definitions

  • the present invention relates to a cooking oven, particularly for household use, as defined in the preamble of claim 1.
  • doors are usually employed which comprise two or three parallel panes, particularly of glass, to allow visual monitoring of the food being cooked in the oven.
  • Prior art cooking ovens have the drawback that they have to prevent the outer pane from reaching excessive temperatures, and become dangerous in case of accidental contact therewith, particularly in case of pyrolytic ovens.
  • a cooking oven is, particularly for household use, is known in the art, of the type that comprises:
  • this cooking oven comprises exhaust means associated with an aperture in the muffle, for drawing air from within said muffle and exhausting it out of the cooking oven.
  • these exhaust means comprise a first channel formed on an upper portion of said delivery duct for the passage of air coming from said aperture, said first channel being associated with a second channel formed on said upper portion of the delivery duct and adapted to draw at least one portion of the air processed by said fan.
  • a further drawback of the above solution is that, since the cooking fumes cannot adequately mix with the air flow processed by the fan, large amounts of condensation build up on the outer front wall of the oven.
  • the main object of the present invention is to obviate the above drawbacks and provide a cooking oven, particularly for household use, which is so designed as to effectively exhaust the air drawn from within said muffle out of the cooking oven.
  • Another object of the present invention is to provide a cooking oven, particularly for household use, comprising exhaust means which are so designed as to ensure optimal performance in exhaustion of the cooking fumes drawn from within the oven muffle, thereby avoiding the build-up of condensation and hence dripping on the outer front wall of the oven.
  • Another object of the present invention is to provide a cooking oven, particularly for household use, comprising a cooling system which is so designed as to allow the closing door of the muffle to ensure high efficiency in thermal insulation and cooling of the outer surface.
  • a further object of the present invention is to provide a cooking oven, particularly for household use, comprising a cooling system which is so designed as to allow the door to ensure adequate visibility of the oven muffle and the food contained therein.
  • the present invention provides a cooking a oven, particularly for household use, incorporating the features of the annexed claims, which are intended as an integral part of the present description.
  • numeral 1 generally designates a cooking oven, particularly for household use, the type that comprises:
  • said fan 11 is a tangential fan, and is driven by a motor 13, advantageously of the type that can be controlled at variable speed by the electronic control system (not shown) of the cooking oven 1.
  • the fan 11 may be a centrifugal or axial fan.
  • the delivery duct 12 has such a shape as to provide optimal air conveyance into the first gap 6A of the door 4; particularly, such delivery duct. 12 is substantially flat and flared and comprises at least one slot 12A for blowing a forced-air flow into said first gap 6A; Figs. 3 and 4 show a plurality of slots 12A.
  • the door 4 of the cooking oven 1 may comprise a third pane 5C, which is adapted to create a second gap 6B with said second pane 5B.
  • the third pane 5C is associated with the door 4 in such a manner as to keep said second gap 6B free of forced-air; nevertheless, the third pane 5C may be also associated with the door 4 in such a manner as to allow air from the cooling system 10 to flow through the second gap 6B.
  • the first gap 6A with the forced air flowing therethrough is the inner one, i.e. the one closer to the muffle 3, and the third pane 5C is the outer plane, also having an aesthetic purpose.
  • the door 4 comprises three panes 5A, 5B, 5C at the most, as the cooling system 10 affords highly effective thermal insulation of the muffle 3 and ensures an adequate temperature of the outer pane 5B, 5C, i.e. the one farther from the muffle 3; as a result, the cooling system 10 of the present invention allows the door 4 to be formed of not more than three panes 5A, 5B, 5C.
  • the walls of said muffle 3 are covered with a heat insulating material, and define a cooking compartment, which generally hold heating means (not shown), adapted to raise the temperature in said muffle 3 to a desired food cooking temperature and, in case of a pyrolytic oven, even to a temperature that can activate the cleaning feature to clean the walls of the muffle 3 by pyrolysis.
  • a space 7 extends between the cabinet 2 and the muffle 3 all around the walls of the muffle 3, to improve thermal insulation between the interior of the muffle 3 and the outer surface of the cabinet 2, said space 7 at least partially accommodating said insulating material, such as glass wool or foam glass.
  • the air to be blown into the first gap 6A may be drawn by the cooling system 10 either from the space 7 and/or from the exterior of the cabinet 2, e.g. through a plurality of slots 2A formed on said cabinet 2.
  • a gasket 8 generally made of rubber or fiberglass, which is placed either on the edge of the muffle 3 or on the door 4; Fig. 1 only shows the upper and lower portions of the gasket 8.
  • the cooking oven 1 also comprises exhaust means (generally designated by numeral 20 in the figures), which are associated with an aperture 3A in the muffle 3, for drawing air from within the muffle 3 and exhausting it out of the oven 1.
  • exhaust means generally designated by numeral 20 in the figures
  • these exhaust means 20 comprise:
  • said first channel 21 has a rectangular sectional shape with a height and a width of about 10 mm and about 70 mm respectively.
  • Figs. 1 and 2 show the position of the channel 22, particularly its second section 22B, whereas Figs. 3 and 4 show the extension of the first section 22A.
  • said at least one portion of air drawn from the first channel 21 is from 10% to 30%, more preferably from 10% to 20%, particularly about 13% of the airflow handled by the fan 11. This will facilitate the outflow of the cooking fumes contained in the muffle 3 without the use of a dedicated fan.
  • said second channel 22 substantially has a U-shape and comprises a third curvilinear section 22 which acts as a connection between said first 22A and second 22B sections.
  • said second channel 22 is formed on a cover 23 which is adapted to be associated with said upper portion of the delivery duct 12.
  • FIG. 2 shows that said cover 23 is so designed as to include a portion 23A that slopes down towards the first channel 21, said portion 23A being particularly located at said second section 22B of the second channel 22.
  • This arrangement allows the air flow in the second channel 22, particularly said second section 22B, to be conveyed towards the first channel 21; furthermore, it allows the air drawn from within said muffle 3 to be easily pulled by the air that flows in the first channel 21, for advantageously improved discharge of the air drawn from within the muffle 3 and contained in the second channel 22.
  • these exhaust means 20 also comprise a plate 30 (as particularly shown in Figs. 1 , 2 and 3 ), which is adapted to be joined to the cover 23 to form the base of the second channel 22; particularly, said plate 30 is fixed under the cover 23 at said second U-shaped channel 22 by known fastener means, such as a plurality of screws 31 (as clearly shown in Figs. 2 and 3 ), which fit into special housings 23B formed on the cover 23.
  • known fastener means such as a plurality of screws 31 (as clearly shown in Figs. 2 and 3 ), which fit into special housings 23B formed on the cover 23.
  • the plate 30 may be fixed to the cover 23 by means of rivets or mechanical interlocking arrangements.
  • said plate 30 comprises an orifice 32 (as shown in Fig. 3 ) to allow the air drawn from within the muffle 3 to flow into the second channel 22, particularly said orifice 32 being located at the first section 22A of the second channel 22.
  • said plate 30 comprises at least one notch 33 to allow the air drawn from within the muffle 3 to flow from the second channel 22 to the first channel 21.
  • said at least one notch 33 has an hopper front shape and is located at the second section 22B of the second channel 22, and allows the air drawn from within the muffle 3 to be pulled through, by the air flow blown by the fan 11 and flowing into the first channel 21, into a third channel 24 formed on an upper portion of said delivery duct 12 and located downstream from the intersection between the first 21 and the second 22 channels.
  • the third channel 24 is at least 250 mm long. In the example of the figures, the length of the third channel 24 is about 300 mm.
  • said at least one notch 33 comprises a plurality of notches 33.
  • the cover 23 is welded, e.g. by vibration welding, to the delivery duct 12, to seal the channels 21, 22 and 24, for the plate 30 to be stably locked in its proper position of use.
  • the exhaust means 20 of the present invention may further comprise an actuator member (referenced 28 in Figs. 1 and 2 ), such as a gate valve, to discriminate, particularly during a cooking cycle, the time in which the cooking fumes are exhausted out of the cooking oven 1 by forced convection, from the time in which the cooking fumes are exhausted out of the cooking oven 1 by natural convection, or the time in which the muffle 3 is kept substantially tight.
  • an actuator member referenced 28 in Figs. 1 and 2
  • a gate valve to discriminate, particularly during a cooking cycle, the time in which the cooking fumes are exhausted out of the cooking oven 1 by forced convection, from the time in which the cooking fumes are exhausted out of the cooking oven 1 by natural convection, or the time in which the muffle 3 is kept substantially tight.
  • the actuator member 28 is advantageously controlled to prevent or minimize the outflow of cooking fumes from the muffle 3 as the latter is being heated, to reduce the power consumption of the cooking oven 1, or during special cooking operations, such as steam cooking.
  • said actuator member 28 is located substantially at the entrance of the first channel 21.
  • said actuator member 28 is associated to drive means (not shown), which allow it to assume:
  • said first P1, second P2 and third P3 operating states of the actuator member 28 as shown in Fig. 2 are such that the position of the actuator member 28 is offset along the first channel 21.
  • the actuator member 28 preferably has a substantially vertical movement; thus, in said second P2 and third P3 operating states the actuator member 28 is located above the position as shown in Fig. 2 as a first operating state P1.
  • said actuator member 28 may be located in the third channel 24, i.e. downstream from the intersection between the first 21 and second 22 channels.
  • the exhaust means 20 of the present invention allow the first 21 and second 22 channels to be joined together substantially proximate to the fan 11; as a result, the air processed by said fan 11 has a wide space available for adequate mixing of the cooking fumes contained in the muffle 3 into the blown air flow that pulls through said cooking fumes out of the cooking oven 1. This will provide exhaust means 20 having an optimized effectiveness in the discharge of the fumes contained in said muffle 3.
  • the second channel 22 is formed with a second section 22B that lies over the first channel 21, improved mixing of the cooking fumes drawn from within said muffle 3 with the air processed by the fan 11 is obtained; this advantageously helps to improve the performances of the exhaust means 20 in exhausting said cooking fumes drawn from the muffle 3 out of the oven 1.

  • the door 2 can be designed in such a manner as to ensure adequate visibility of the muffle 3 and the food contained therein, particularly because such design prevents said first gap 6A from becoming fouled and hence from requiring difficult cleaning operations.
  • the cooling system 10 allows the closing door 4 of the muffle 3 to ensure efficient heat insulation and cooling of the outer surface of said door 4.
  • the exhaust means 20 are designed in such a manner that the air drawn from within said muffle 3 can be released above an upper edge 4A of the door 4, preferably in a space 40 created between the upper edge 4A of the door 4 and a lower area 42 of a front panel 41.
  • the air in said third channel 24 flows through at least one outlet 25 (as particularly shown in Figs. 2 and 4 ) and is released into said space 40.
  • the cover 23 is adapted to be joined to said upper portion of the delivery duct 12 to enclose said first 21, second 22 and third 24 channels.
  • Figs. 1 , 2 and 3 further show that the exhaust means 20 of the present invention also comprise:
  • the actuator member 2 can determine whether the cooking fumes have to be exhausted from the muffle 3 by natural convection only or with the help of forced convection.
  • the actuator member 28 may be designed in such a manner as to allow discrimination of the time in which the muffle 3 is kept substantially tight and the time in which the muffle 3 is in fluid communication with the exterior.
  • the upper portion of the delivery duct 12 also comprises a plurality of coupling means 30 for fixing functional elements of the cooking oven 1 to said delivery duct 12.
  • These functional elements are schematically shown in Fig. 4 and may include one or more of the following elements: an electronic card 51, an interface card 52, a door lock device 53 for locking the door 4 and so on.

  • the safety switch is advantageously fixed to the cooking oven 1 by being joined to the delivery duct 12 through the coupling means 50.
  • the assembly of the cooking oven 1 is greatly simplified, due to its reduced number of components which also involves lower costs. Furthermore, the functional parts are positioned in a more accurate manner, and may be more reliably and safely secured as compared to the prior art.
  • cooling system 10 is so designed as to generate a downward directed forced-air flow in said first gap 6A; forced air flows through said at least one slot 12A, and then is directed from the upper edge 4A to a lower edge 4B of the door 4.
  • the air flow for cooling the door 4 is separate from the hot flow of cooking fumes, it can adequately cool the entire door 4, including the upper edge 4A, which is where the user is more exposed to accidental contact, as it is close to the front panel 41 with the interface devices (not shown) of the cooking oven 1.

  • the flow is diverted in a manner such that it has at least one horizontal motion component.
  • Such deflector means 9B comprise a pair of deflectors, each possibly consisting of a particular element applied to the structure of the door 4 or obtained by appropriately shaping a structural element of the door 4.
  • the deflector means 9B may be provided as a single element having both the purpose of securing the first pane 5A, diverting the flow from the first gap 6A, and also, advantageously, collecting any condensation built up the first pane 5A.
