- 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.

- 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.

- 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.

- 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.

This will avoid difficult cleaning operations.
- Another advantage of the cooking oven 1 of the present invention is the provision of a plurality of coupling means 50 on the upper portion of the delivery duct 12; these coupling means 50 provide optimal fixation of functional elements of the cooking oven 1 to said delivery duct 12.

- the particular embodiment of the cooking oven 1 of the present invention allows the door 4 to exhibit high efficiency in heat insulation and cooling of the outer surface.
- the particular embodiment of the cooking oven 1 of the invention has the additional advantage of using a single fan 11 to both draw air from the muffle 3 and exhaust it above the upper edge 4A of the door 4 and to blow a forced-air flow into the first gap 6A.

Description
- The present invention relates to a cooking oven, particularly for household use, as defined in the preamble of
claim 1. - In household cooking ovens, 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.
- In an attempt to obviate this drawback, it is known in the art to form a door comprising at least one first and one second panes, which are adapted to create a gap therebetween, to reduce the transfer of heat from the oven to the outer pane.
- Nevertheless, in spite of said gap, the outer pane still usually reaches an excessive temperature.
- As a result, it is known in the art to blow air into said gap, by either natural or forced convection, to improve the cooling effect on the panes of the door of a cooking oven, particularly of the outer pane, as viewed relative to a muffle of the oven.
- For instance, a cooking oven is, particularly for household use, is known in the art, of the type that comprises:
- a muffle which is adapted to be closed by a door,
- at least one first and one second panes, which are adapted to create a gap in said door,
- a cooling system located above said muffle and comprising a fan and a delivery duct, which are adapted to blow air into said gap.
- According to the above described solution, 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.
- Particularly, 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.
- Nevertheless, this prior art solution suffers from certain drawbacks, as the area where the first and second channels join together is too close to the oven door; therefore, the air processed by the fan has too little space available for adequately facilitating the outflow of cooking fumes contained in the muffle.
- This inevitably causes the exhaust means to be poorly effective in exhausting the air drawn from within the muffle out of the cooking oven.
- 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.

- 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. In view of fulfilling such objects, 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. - Further objects, features and advantages of the present invention will become apparent from the following detailed description and from the annexed drawings, which are only given by way of non-limiting example, in which:

fan 11 may be a centrifugal or axial fan. - Furthermore, the
delivery duct 12 has such a shape as to provide optimal air conveyance into thefirst gap 6A of the door 4; particularly, such delivery duct. 12 is substantially flat and flared and comprises at least oneslot 12A for blowing a forced-air flow into saidfirst gap 6A;Figs. 3 and4 show a plurality ofslots 12A. - As particularly shown in
Fig. 1 , the door 4 of thecooking oven 1 may comprise athird pane 5C, which is adapted to create asecond gap 6B with saidsecond pane 5B. - Preferably, the
third pane 5C is associated with the door 4 in such a manner as to keep saidsecond gap 6B free of forced-air; nevertheless, thethird pane 5C may be also associated with the door 4 in such a manner as to allow air from thecooling system 10 to flow through thesecond gap 6B. - In a preferred embodiment, if the
cooking oven 1 comprises a plurality ofgaps first gap 6A with the forced air flowing therethrough is the inner one, i.e. the one closer to the muffle 3, and thethird pane 5C is the outer plane, also having an aesthetic purpose. - Preferably, the door 4 comprises three
panes cooling system 10 affords highly effective thermal insulation of the muffle 3 and ensures an adequate temperature of theouter pane cooling system 10 of the present invention allows the door 4 to be formed of not more than threepanes - As is known in the art, 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.
- Furthermore, 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, saidspace 7 at least partially accommodating said insulating material, such as glass wool or foam glass. - It shall be noted that the air to be blown into the
first gap 6A may be drawn by thecooling system 10 either from thespace 7 and/or from the exterior of the cabinet 2, e.g. through a plurality ofslots 2A formed on said cabinet 2. - The sealing effect between the door 4 and muffle 3 is ensured by 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 thegasket 8. - The
cooking oven 1 also comprises exhaust means (generally designated bynumeral 20 in the figures), which are associated with anaperture 3A in the muffle 3, for drawing air from within the muffle 3 and exhausting it out of theoven 1. - According to the present invention, these exhaust means 20 comprise:
- a
first channel 21 formed on an upper portion of saiddelivery duct 12 and adapted to draw at least one portion of the air processed by saidfan 11; - a
second channel 22 for the passage of air coming from saidaperture 3A, saidsecond channel 22 comprising afirst section 22A substantially pointing in the direction of thefan 11 and asecond section 22B having such orientation as to lie over thefirst channel 21. - Advantageously, said
first channel 21 has a rectangular sectional shape with a height and a width of about 10 mm and about 70 mm respectively. - The position of the
channel 22, particularly itssecond section 22B, is especially visible inFigs. 1 and2 , whereasFigs. 3 and4 show the extension of thefirst section 22A. - Preferably, 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 thefan 11. This will facilitate the outflow of the cooking fumes contained in the muffle 3 without the use of a dedicated fan. - As particularly shown in
Fig. 4 , saidsecond channel 22 substantially has a U-shape and comprises a thirdcurvilinear section 22 which acts as a connection between said first 22A and second 22B sections. - Preferably, said
second channel 22 is formed on acover 23 which is adapted to be associated with said upper portion of thedelivery duct 12. - Furthermore, particularly
Figure 2 shows that saidcover 23 is so designed as to include aportion 23A that slopes down towards thefirst channel 21, saidportion 23A being particularly located at saidsecond section 22B of thesecond channel 22. - This arrangement allows the air flow in the
second channel 22, particularly saidsecond section 22B, to be conveyed towards thefirst channel 21; furthermore, it allows the air drawn from within said muffle 3 to be easily pulled by the air that flows in thefirst channel 21, for advantageously improved discharge of the air drawn from within the muffle 3 and contained in thesecond channel 22. - According to the present invention, these exhaust means 20 also comprise a plate 30 (as particularly shown in
Figs. 1 ,2 and3 ), which is adapted to be joined to thecover 23 to form the base of thesecond channel 22; particularly, saidplate 30 is fixed under thecover 23 at said second U-shapedchannel 22 by known fastener means, such as a plurality of screws 31 (as clearly shown inFigs. 2 and3 ), which fit intospecial housings 23B formed on thecover 23. - Alternatively, the
plate 30 may be fixed to thecover 23 by means of rivets or mechanical interlocking arrangements. - In a preferred embodiment, said
plate 30 comprises an orifice 32 (as shown inFig. 3 ) to allow the air drawn from within the muffle 3 to flow into thesecond channel 22, particularly saidorifice 32 being located at thefirst section 22A of thesecond channel 22. - Furthermore, said
plate 30 comprises at least onenotch 33 to allow the air drawn from within the muffle 3 to flow from thesecond channel 22 to thefirst channel 21. - Preferably, said at least one
notch 33 has an hopper front shape and is located at thesecond section 22B of thesecond channel 22, and allows the air drawn from within the muffle 3 to be pulled through, by the air flow blown by thefan 11 and flowing into thefirst channel 21, into athird channel 24 formed on an upper portion of saiddelivery duct 12 and located downstream from the intersection between the first 21 and the second 22 channels. For optimized mixing of the cooking fumes in the air flow that pulls them through, thethird channel 24 is at least 250 mm long. In the example of the figures, the length of thethird channel 24 is about 300 mm. - As particularly shown in the annexed
Figs. 2 and3 , said at least onenotch 33 comprises a plurality ofnotches 33. - Once the
plate 30 is attached to it, thecover 23 is welded, e.g. by vibration welding, to thedelivery duct 12, to seal thechannels 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 and2 ), such as a gate valve, to discriminate, particularly during a cooking cycle, the time in which the cooking fumes are exhausted out of thecooking oven 1 by forced convection, from the time in which the cooking fumes are exhausted out of thecooking 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 thecooking oven 1, or during special cooking operations, such as steam cooking. - Preferably, said
actuator member 28 is located substantially at the entrance of thefirst channel 21. - Furthermore, said
actuator member 28 is associated to drive means (not shown), which allow it to assume: - a first operating state P1 (as shown by a solid line in
Fig. 2 ), in which it completely closes thefirst channel 21 and prevents the air blown by thefan 11 to flow into saidfirst channel 21. Substantially, in said first operating state P1, the cooking fumes may be exhausted out of thecooking oven 1 only by natural convention and, as a result, a very little flow of fumes comes out of the muffle 3; - a second operating state P2 (as shown by a first broken line in
Fig. 2 ), in which it partially closes thefirst channel 21 and allows only a portion of the maximum air flow that can be blown by thefan 11 to flow into saidfirst channel 21. As a result, in said second operating state P2, the air drawn from within the muffle 3 and contained in thesecond channel 22 is only partially pulled through by the air flow blown by thefan 11, and only a reduced flow of cooking fumes is exhausted out of thecooking oven 1; - a third operating state P3 (as shown by a second broken line in
Fig. 2 ), in which it keeps thefirst channel 21 completely open and allows the whole air flow blown by thefan 11 to flow into saidfirst channel 21. As a result, in said third operating state P3, the air drawn from within the muffle 3 and contained in thesecond channel 22 is wholly pulled through by the air flow blown by thefan 11, and the cooking fumes are entirely exhausted out of thecooking oven 1. - It shall be noted that said first P1, second P2 and third P3 operating states of the
actuator member 28 as shown inFig. 2 are such that the position of theactuator member 28 is offset along thefirst channel 21. In fact, theactuator member 28 preferably has a substantially vertical movement; thus, in said second P2 and third P3 operating states theactuator member 28 is located above the position as shown inFig. 2 as a first operating state P1. - Alternatively, said
actuator member 28 may be located in thethird 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 saidfan 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 thecooking oven 1. This will provide exhaust means 20 having an optimized effectiveness in the discharge of the fumes contained in said muffle 3. - Also, as the
second channel 22 is formed with asecond section 22B that lies over thefirst channel 21, improved mixing of the cooking fumes drawn from within said muffle 3 with the air processed by thefan 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 theoven 1. - Moreover, by providing the
plate 30 with at least onenotch 33, the air drawn from within the muffle 3 is pulled through by the flow of air blown by thefan 11 in an improved manner. - Furthermore, the exhaust means 20 of the present invention allow the air flow drawn from within said muffle 3 to be kept separate from the flow of air blown into said
first gap 6A by thecooling system 10. With the arrangement of keeping the two air flows separate from each other, 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 saidfirst gap 6A from becoming fouled and hence from requiring difficult cleaning operations. - Also, 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 aspace 40 created between theupper edge 4A of the door 4 and alower area 42 of afront panel 41. - There may be a short distance between the
lower area 42 of thefront panel 41 and theupper edge 4A of the door 4, indicatively ranging from about 2 mm and about 6 mm (and particularly nominally 4 mm or 4.5 mm), to create a nearly seamless surface between thefront panel 41 and the door 4, thus leading to advantages in terms of exterior appearance and ease of cleaning of thecooking oven 1. - The, the air in said
third channel 24 flows through at least one outlet 25 (as particularly shown inFigs. 2 and4 ) and is released into saidspace 40. - Optimal mixing of cooking fumes into the air flow blown by the
fan 11 prevents condensation build-up both on thefront panel 41 and on theupper edge 4A of the door 4. - Thus, the
cover 23 is adapted to be joined to said upper portion of thedelivery duct 12 to enclose said first 21, second 22 and third 24 channels. -
Figs. 1 ,2 and3 further show that the exhaust means 20 of the present invention also comprise: - a
diverter element 26, particularly having a wedge shape, which is located in saidthird channel 24 to divert the air flow towards said at least oneoutlet 25. Thediverter element 26 is preferably fitted in by laying it on thedelivery duct 12 and securing thecover 23 to said upper portion of thedelivery duct 12, thecover 23 being for instance secured by vibration or ultrasonic welding. Thus, thediverter element 26 is permanently trapped in position in its operating seat. Alternatively, thediverter element 26 may be formed of one piece with thedelivery duct 12 or thecover 23; - a
tubular element 27 associated with theaperture 3A of the muffle 3 and connected through a gasket (not shown) to a slit 14 (as shown inFig. 3 ) of thedelivery duct 12 to allow the cooking fumes drawn from within themuffle 12 to reach saidsecond channel 22. - In the embodiment of
Fig. 2 , 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. - Alternatively, 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. - This may be achieved in various manners (not shown), including the following:
- the actuator member may be a butterfly valve (possibly having an adjustable opening degree) and be interposed between the
tubular element 27 and thesecond channel 22; - the actuator member may be inserted in the
first channel 22A and may comprise a shutter having the same section as thefirst channel 22A and a drive mechanism for driving the shutter about a vertical axis, such that the shutter may move (possibly assuming intermediate positions) between a rest position parallel to the flow through thefirst channel 22A and a closed position orthogonal to the flow through thefirst channel 22A; - the actuator member may be conceived in the form of a movable plate, adjacent to the
plate 30 and capable of moving parallel thereto to obstruct or clear, as a gate and as needed, the one ormore notches 33. - According to the present invention, the upper portion of the
delivery duct 12 also comprises a plurality of coupling means 30 for fixing functional elements of thecooking oven 1 to saiddelivery duct 12. These functional elements are schematically shown inFig. 4 and may include one or more of the following elements: anelectronic card 51, aninterface card 52, adoor lock device 53 for locking the door 4 and so on. - Preferably, said coupling means 50 are formed by the same molding operation that forms the
delivery duct 12, which is made of plastic. - If the
cooking oven 1 comprises a microwave generator for at least one microwave-based or microwave-assisted cooking cycle, the door 4 has at least one protective shield therein to prevent microwaves from propagating therethrough, and thecooking oven 1 comprises a safety switch (not shown), which is designed to automatically turn off the microwave generator as the door 4 is opened. The safety switch is advantageously fixed to thecooking oven 1 by being joined to thedelivery duct 12 through the coupling means 50. - It will be appreciated that, by providing the
delivery duct 12 with coupling means 50 (such as ridges or seats) formed of one piece with thedelivery duct 12, the assembly of thecooking 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. - Concerning the
cooling system 10, it is so designed as to generate a downward directed forced-air flow in saidfirst gap 6A; forced air flows through said at least oneslot 12A, and then is directed from theupper edge 4A to alower edge 4B of the door 4. - Since 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 thefront panel 41 with the interface devices (not shown) of thecooking oven 1. - Preferably, an
air conveyor element 4A is associated with saidupper edge 4A, for conveying the air flow from thecooling system 10 into thefirst gap 6A and/or thesecond gap 6B. - Said
conveyor element 9A has a profile of such a shape as to change the direction of the air flow from thecooling system 10 by about 90°. Theconveyor element 9A may be associated with the door 4 at the inlet section of thefirst gap 6A, or it may be associated with any other component of thecooking oven 1 at the outlet section of thedelivery duct 12. - Furthermore, the
lower edge 4B comprises deflector means 9B associated with said first 5A and second 5B panes, said deflector means 9B being bent in a direction opposite to the muffle 3; the provision of the deflector means 9B allows the air flow from saidfirst gap 6A and/or saidsecond gap 6B to be directed towards an external portion of theoven 1, particularly a portion external to said door 4. Advantageously, 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.
- As an alternative, 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 thefirst gap 6A, and also, advantageously, collecting any condensation built up thefirst pane 5A. - Particularly,
Figs. 3 and4 show that thecooling system 10 comprises acover 60 that is coupled to the underside of thedelivery duct 12, saidcover 60 having anopening 61 for the passage of thetubular element 27 associated with theaperture 3A of the muffle 3. - Preferably, said
cover 60 is made of sheet metal and is secured to the sides of thecooking oven 1; furthermore an insulating material (not shown) is interposed between saidcover 50 and the muffle 3, to prevent any excessive heating of the air to be blown into saidfirst gap 6A, due to the heat of said muffle 3. - The above description clearly shows the advantages of a cooking oven, particularly for household use, according to the present invention.
- Particularly, 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 saidfan 11 has a wide space available for adequate mixing of the cooking fumes contained into the air flow that pulls them through out of thecooking oven 1. This will provide exhaust means 20 having an optimized effectiveness in the discharge of the fumes contained in said muffle 3, which also do not form condensation on the outer front wall of thecooking oven 1. - Also, as the
second channel 22 is formed with asecond section 22B that lies over thefirst channel 21, improved mixing of the cooking fumes drawn from within said muffle 3 with the air processed by thefan 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 theoven 1. - Moreover, by providing the
plate 30 with at least onenotch 33, the air drawn from within the muffle 3 is pulled through by the flow of air blown by thefan 11 in an improved manner. - The discharge of the air drawn from within the muffle 3 is further facilitated in that it is pulled through by the air flow that is blown by the
fan 11, i.e. at least one portion of air from saidfan 11. - Furthermore, the possibility of keeping the flow of air drawn from within said muffle 3 separate from the flow of air blown into said
first gap 6A allows the door 4 to be designed in such a manner as to allow adequate visibility of the muffle 3 and the food contained therein, and to prevent said first gap 6 from being fouled thereby. This will avoid difficult cleaning operations. - Another advantage of the
cooking oven 1 of the present invention is the provision of a plurality of coupling means 50 on the upper portion of thedelivery duct 12; these coupling means 50 provide optimal fixation of functional elements of thecooking oven 1 to saiddelivery duct 12. - A further advantage is that said
cooling system 10 can generate a downward-directed air flow in saidfirst gap 6A, i.e. a flow directed from theupper edge 4A to alower edge 4B of the door 4; this embodiment advantageously ensures adequate cooling of theupper edge 4A of the door, which is the most dangerous for the user, as it is the one where an accidental contact is most likely to occur. - Thus, the particular embodiment of the
cooking oven 1 of the present invention allows the door 4 to exhibit high efficiency in heat insulation and cooling of the outer surface. - Furthermore, the particular embodiment of the
cooking oven 1 of the invention has the additional advantage of using asingle fan 11 to both draw air from the muffle 3 and exhaust it above theupper edge 4A of the door 4 and to blow a forced-air flow into thefirst gap 6A. - Many variants may be envisaged for the cooking oven as illustratively disclosed herein, without departure from the novel concepts of the invention, and the disclosed details may be implemented in different manners, or replaced by technically equivalent parts.
- Therefore, it will be appreciated that the present invention is not limited to the cooking oven, particularly for household use, as described above, but is susceptible to various modifications, improvements, replacements of equivalent elements and parts, without departure from the scope of the invention, as better defined in the following claims.
