Definitions
- the present invention relates to cooking ovens and has been developed particularly with reference to convection cooking ovens.
- the domestic ovens for cooking foods typically comprise a bearing structure, which is associated to a muffle and a front door which closes the muffle frontally .
- a metal bulkhead formed by a metal sheet, facing to the rear wall of the muffle.
- This bulkhead divides the internal cavity of the muffle in a front cooking chamber, which extends between the door and the bulkhead, and a rear air distribution chamber, which extends between the bulkhead and the rear wall of the muffle.
- In the cooking chamber there is one or more shelves generally positioned at different heights, where food containers can be placed , to define different levels of cooking.
- the air distribution chamber is operatively arranged at least one heating resistance , which usually has a circular shape, as well as a fan, that is usually positioned in the area circumscribed by the resistance.
- the fan impeller is usually a centrifugal one and, the distribution chamber wherein it's located has an output section, for the airflow to the cooking chamber, as well as an input section.
- the output section usually includes a plurality of passageways, which are normally in peripheral positions with respect to the distribution chamber, generally outlined between the bulkhead and the rear or side wall of the muffle.
- the bulkhead has a smaller size compared to the size of the rear wall of the muffle and has a folded back edge, which is shaped in order to define the areas for the anchorage of the bulkhead to the rear wall of the muffle.
- the edge is cut, or otherwise shaped, also in order to outline the above mentioned peripheral airflow routes.
- the input airflow section of the distribution chamber is instead located in a central area of the bulkhead, configured substantially as a grid - usually by means of a multitude of holes close to each other -- located in front of the fan impeller. In this way the air is heated by the electric resistance and is pushed towards the air output devices of the distribution chamber, to flow substantially along the side walls of the muffle, toward the cooking chamber.
- the intermediate bulkhead of the muffle has essentially the task to direct the airflow inside the cavity of the muffle, using the grid that is normally dimensioned to ensure sufficient suction of "exhausted” air and prevent the risk of user injury.
- the cooking method resulting from this air distribution system depends mainly on the airflow of return - namely the sucked airflow in the central area of the bulkhead - that invests the foods placed in the oven at any level of shelves.
- the result is that the cooking is possible due to a quite chaotic movement of the airflow, which depends on the geometric shape of the grid of the bulkhead and on the direction of rotation of the fan impeller.
- Document DE 10 2008 042473 A1 discloses a cooking chamber unit for forming two cooking support regions and two gas outlet devices comprising two gas outlet units that open in to the support regions, respectively.
- EP 2735806 A1 discloses a household cooking oven provided with a bulkhead, wherein the frontal inlet comprises a plurality of circular openings distributed along the longitudinal direction.
- the main purpose of the present invention is essentially to provide a ventilated cooking oven in which the distribution of the air, in the cooking chamber, takes place with a controlled method, particularly in order to obtain a substantially symmetrical and/ or balanced distribution among the different levels of cooking.
- number 1 indicates a household cooking oven according to the invention.
- the oven has a bearing structure or casing, shown with 2, in the front of which there is a control panel 3.
- a control panel 3 In the front of the casing 2 is also hinged, particularly in the lower edge, a door 4, provided with a handle 4a.
- the muffle 5 has a rigid metallic body, having two side walls, a bottom wall, a top wall and a rear wall; in figure 2 is represented the rear wall, denoted by 5a, while Figure 3 shows partially the lower wall 5b and the upper 5c, and one of the side walls 5d.
- the muffle 5 is preferably protected by a layer of insulation, already known and not represented.
- the muffle 5 defines a cavity, that can be frontally opened and closed by the door 4, in which is present a rear bulkhead 10, in a position generally facing the rear wall of the muffle 5a: in this way the bulkhead 10 divides the inside of the muffle 5 in a front cooking chamber that extends between the door 4 and the bulkhead 10, and a rear air-distribution chamber that extends between the bulkhead 10 and the rear wall of the muffle 5a.
- the supports consist in guides 6 shaped on the side walls of the muffle 5d, but in alternative embodiments, guides having a similar function can be represented by added grid , applied to the side walls 5d.
- guides 6 of the two opposite side walls 5d of the muffle are inserted in a sliding manner the edges of these shelves , one of these - here represented by an oven baking tray - is shown with number 7 in Figures 2 , 3 and 7 .
- this container 8a is represented a generic cooking vessel, in the example a baking pan, having a lateral size dimension smaller than the distance between the two side walls of the 5d muffle: this container 8a will be placed in a cooking shelf - schematically represented only in Figures 2 and 7 , where it is shown with 8 - having an appropriate size to engage its respective guides 6 of the lateral walls 5d.
- the guides 6 are defined at different heights, in order to arrange in the cooking chamber a plurality of different positions for different levels of cooking: as a simple example, this different cooking levels are shown in Figure 7 with the letters from "A" to "E ", from the bottom upwards .
- the cooking chamber is preferably but not necessarily equipped with suitable heating elements.
- two electric resistances or grill (broil) resistance - represented only in figure 3 , where one of them is indicated with 9.
- the resistance 9, usable particularly to cook food in the cooking chamber by intense radiant heat from the upper broil element, is placed within the muffle 5, on its upper wall 5b.
- the impeller 12 In the air distribution chamber defined between the rear wall of the muffle 5a and the bulkhead 10 are operatively arranged at least one electrical heating resistance 11 and the impeller 12 of a fan, particularly a centrifugal fan with axial suction and radial delivery.
- the fan motor marked with 13 in figure 2 , is assembled outside the muffle 5, behind its rear wall 5a, with its drive shaft passing through a slot in the rear wall.
- the impeller 12 rotates preferably within the region where the resistance 11 is placed, here defined as "rear", which has preferably a shape at least partially annular.
- the peripheral profile of the bulkhead 10 has perimeter size generally lower than that of the rear wall of the muffle 5a, as seen for example in Figures 2 , 3 and 7 .
- the assembly of the resistances 9 does not necessarily imply they pass through holes or breaks in the bulkhead 10.
- the different sizes between the perimeter wall 10 and rear wall 5a also allow, for example, to install a lamp directly on this last one - indicated with 14 only in Figure 3 - to light up inside when necessary the cooking chamber.
- the distribution chamber has an outlet section for the delivery of the air, through the fan impeller 12 , which forcibly inflates the air previously heated by the resistance 11 in the cooking chamber and an inlet section or recycling, through the impeller 12, which can draw air from the cooking chamber and then forces it back inside the same cooking chamber through the outlet section.
- This air is later again heated by the resistance 11.
- the outlet section comprises, similarly to the working principles of ventilated ovens, air passageways in generally peripheral positions of the air distribution chamber.
- the inlet section of the air distribution chamber of the oven 1 is not formed with a traditional grid of holes or similar shapes in the wall of the bulkhead 10.
- the inlet section comprises an air-suction cavity or chamber in the bulkhead 10.
- This air-suction cavity, 20 in Figures 2 and 3 has at least one inlet in the bulkhead 10 toward the cooking chamber and at least one outlet in the rear bulkhead facing towards the fan impeller 12 .
- the bulkhead 10 has a structure partially box-shaped to easier deliver the airflow in the internal cavity 20.
- the bulkhead 10 consists of at least two parts joined to get a cavity chamber, where the two parts in question can be welded, or stapled or otherwise made integral with each other (for example with screws or similar) .
- the bulkhead consists of two parts: the rear part 10a and the front one 10b, consisting of metal plates sheared and shaped, welded together.
- the rear part 10a defines at least one outlet 21, preferably in a central region that is generally flat.
- the periphery of the part 10a is instead preferably shaped in order to create areas for the complete anchorage of the bulkhead 10 to the rear wall 5a of the muffle.
- the peripheral part 10a that is generally preferably bent backwards, defines an upper zone 10a1 for anchoring, for example with screws, of the bulkhead 10 to the wall 5a, and a lower zone 10a2 for the support of the bulkhead 10 to the wall 5a. (of course, you can also fix the bulkhead 10 to the 5a wall in its lower parts).
- the peripheral profile of the part 10a is shaped, in its allocation 10a3, between the area 10a1 and the area 10a2, in order to create, together with the rear wall of the muffle 5a, passageway routes for delivery of the air outlet and then inlet from air-distribution chamber.
- the edge regions 10a3 are sliced in a way to lie along a vertical plane that is generally in parallel position far-between from a plane defined by the edges of the areas 10a1 and 10a2, as shown for example in Figure 5 ; in this way, when the bulkhead 10 is assembled inside the muffle 5, between the edge of the regions 10a3 and the front surface of the rear wall 5a are defined the above mentioned peripheral airflow passageways at least partially implementing the outlet section of the distribution chamber: these passageways are marked with 22 in the figures 3-6 .
- the front part 10b of the bulkhead 10 is shaped in order to define the cavity 20, together with the rear part 10a.
- the part 10b has a C shaped section.
- At least a cavity inlet 20 comprises a plurality of longitudinally extended inlet openings. These inlet openings are shown in images 4-6 with symbols from 23a to 23e but later, in other drawings, where not strictly needed from description, they will be all referred to as 23.
- the inlet openings 23 comprises a plurality of slits which extend substantially horizontally between two opposite lateral regions of the bulkhead 10 or the air-suction cavity 20, with such a slits that extend at different heights. Still with reference to the oven, one or more inlet openings 23 each have a mouth defined by a respective lip 24 projecting from the front 10b of the bulkhead 10 towards the cooking chamber. However, it has to be pointed out that the presence of the lips inlet 24 is merely optional and does not constitute an essential feature for the implementation of the invention. In the example shown, therefore, the openings 23 with its lips 24 are defined from the front 10b of the bulkhead 10.
- each inlet opening 23 extends in length between those two opposite lateral regions of the front of the bulkhead 10 or air-suction cavity 20, in a continuous way; in possible but not represented embodiment, however, one or more of the openings 23 can be interrupted and be constituted by a plurality of individual openings or slits horizontally aligned.
- the openings 23 may have same or may have different passage sections.
- the openings 23a-23c have substantially the same passage section, whereas, the openings 23d and 23e, have smaller passage section, being them shorter than the other.
- at least a pair of openings or slits are closer to each other with respect to other two slits in the plurality of ovens.
- the rear part 10a of the bulkhead 10 comprises at least one outlet opening 21 of the air-suction cavity or chamber 20.
- the outlet section of the cavity may consist in a grid of holes or only in a grid portion 10a.
- the preferred embodiment is provided with a single opening 21, preferably essentially coaxial to a rotation axis of the fan impeller 12 .
- the single opening 21 has essentially elliptical profile with a vertical major axis.
- a substantially elliptical opening 21 provides a larger passageway section than a circular one without affecting the performance of the impeller 12.
- the outlet 21 includes two areas (upper and lower respect to the axis of the impeller 12) where the inlet section is bigger, and two areas (the lateral areas respect to the axis of the impeller 12) which help the compression of the fluid: the combination of these geometries allows to obtain an outlet speed of the air from the impeller 12 in a more higher and homogeneous way compared to a circular opening.
- the back portion 10a of the bulkhead 10 has a projecting lip 21a oriented toward the impeller 12 of the fan, delimiting the at least one outlet 21.
- the lip 21a provides a continuity radius that allows to get closer the air suction section represented by the outlet 21 and the front face of the fan 12, improving its efficiency .
- the air suction cavity 20 has a peripheral profile with two opposite sides having an alternation of crest and valley (20a, 20b) at intermediate heights respect to the inlet openings 23.
- the opposite sides of the peripheral profile of the cavity 20 have alternating crests and valleys, some of which indicated with 20a and 20b, where the inlet opening 23 have opposite end regions each extending within the boundary of a respective crest. Said valleys allow to guide the air flow within the cavity 20 and meantime avoid the presence of dead volumes that could affect the intake air flow from the impeller 12.
- the bulkhead 10 includes some deflector elements which are part of the outlet section of the air distribution chamber, whose function is correcting the direction of air flow towards the zone of interest, specifically based on the inertia of motion generated by the impeller.
- the two deflectors 15 are provided in the back portion 10a of the bulkhead 10, in opposed zones of its upper portion.
- the two deflectors 15 have a not speculate positioning : in the example they have a curved profile, roughly arc of a circle, and are arranged one with the concavity facing upwards (the deflector 15 to the right of Figure 4 ) and the other one with the concavity facing downwards (the deflector 15 to the left of Figure 4 ), in order to address properly the supply air flow of the impeller 12.
- Deflector's positioning may vary in shape and number according to to the shape and direction of rotation of the impeller 12: the represented example refers to an impeller 12 rotating in a clockwise direction.
- the cooking chamber has at two opposite lateral walls 5d of the muffle 5, guides 6 to support removable shelves 7,8 in a plurality of different height positions, or cooking levels, schematically referred as A-E in figure 7 .
- the inlet openings 23 of the air-suction cavity 20 and the guides 6 being in such position that, in at least one of said height position A-E, a shelf 7,8 extends at an height that is intermediate to two said inlet openings 23.
- a shelf 7,8 extends at an height that is intermediate to two said inlet openings 23.
- the drip pan 7 occupies the position B, lying substantially opposite the lowest opening 23a of the bulkhead 10: this is substantially due to the fact that the drip pan 7 is higher than the shelf 9: it will be appreciated, however, that placing the shelf 8 in position B in place of the dripping pan 7, it will at an intermediate level between the openings 23a and 23b.
- FIG. 8 represents such a case, where the reference numbers are the same as in the previous figures, to identify elements technically equivalent to the ones described above.
- the inlet section of the air distribution chamber or cavity includes an additional opening 23f, whose shape may be similar to the openings 23a-23c, provided in correspondence of the lower side of the peripheral profile of cavity 20.
- positions A and B are commonly used for "multilevel” cooking, namely for 3 and 2 levels. Also, positions A and B can be used in case food and/or containers are bulky in the height dimension.
- Openings 23 could be substantially equidistant in height, as depicted for openings 23a-23d (not for 23d-23e), but, in alternative implementations, their mutual distance could be even different: generally speaking, the height and/or the mutual distance of openings 23 is determined by cooking levels (A-E) defined in the cooking chamber and by typology and number of convection cooking allowed to the oven 1 user.
- Figure 9 shows, as an example, a different position for openings 23 compared to figures 5 and 8 , where there is not opening 23a and the highest opening 23e is provided in correspondence to the upper side of the peripheral profile of cavity 20.
- the air flow forced by the impeller 12 is more controlled than in traditional solutions.
- the air-suction generated by the impeller in influenced by the presence of the cavity 20: in other words, air-suction isn't a directly from the cooking chamber, but through the cavity 20: the negative pressure that occurs within the cavity, by means of openings 23, generates the air recycling from the cooking chamber. Openings 23 allow the air recycling from well identified zones of the bulkhead 10, in order to create respective zones of controlled heating, with a substantially symmetrical and balanced distribution among the different cooking levels, as defined by tracks 6. In the traditional known architectures the air flow is not controlled, neither in blowing nor in suction.
- the air-suction cavity 20 creates a volume or storage unit from where the impeller 12 can suck without any impact onto the air flow within the cooking chamber.
- the cavity could even be extended beyond the air-suction zone of impeller 12; above all, the air-flow sucked by the cooking chamber into the distribution chamber is essentially determined by the shape of the bulkhead 10, namely by its openings 23, not by impeller 12.
- Openings 23 allow the air suction, by creating a kind of layers of hot air, which in turn transfer the heat to the food under cooking.
- Provided openings 23 are independent each other, they can assure a multi-level cooking: when 2 shelves are put inside the oven, actually resulting into a 2-levels cooking, each of them is supplied by at least two openings 23, with related air flows, below and above each shelf.
- openings 23 are even extended to the lower part of bulkhead 10, in order to generate a retrieving effect even below the cooking level B.
- the cavity 20 and the related lowest inlet opening for instance the 23f
- oven 1 could even be deprived of heating resistance below the lower wall 5b of muffle 5.
- openings 23 can have different passage sections , and then different air flow rate, allowing to differentiate cooking times over different levels A-E.
