Description

Technical Field

[0001] The invention relates to an appliance for cooking dishes according to the preamble of claim 1 , which is used in the field of cooking appliances for cooking. Background Art

[0002] Appliances for cooking dishes are known in the prior art which comprise an oven defining a cooking compartment selectively accessible by means of a door and a hob arranged above the oven.

[0003] During the cooking of food, the door tends to rise to the temperature of the cooking compartment, which is typically between 150° and 250°.

[0004] To prevent accidental burns, oven manufacturers have deemed it necessary to cool the outer wall of the door where the user may come into contact.

[0005] In this respect, it is known to obtain a cooling cavity in the door of the oven, causing a flow of air to flow in said cooling cavity, reducing the temperature of the door by convection.

[0006] The aforementioned cavity is generally made by spacing apart the inner wall and the outer wall of the door in the thickness direction.

[0007] The air flow passing through the cavity is then discharged into the environment surrounding the oven by means of thin discharge slits having an outlet section smaller than the section of the cavity, aiming at increasing the velocity of the air flow.

[0008] This air flow, also called air curtain, exiting from the door can cause discomfort to the user in the vicinity of the appliance during the preparation of a dish, particularly due to its thermal and kinetic energy.

[0009] Furthermore, the aforementioned air flow exiting from the door carries traces of the cooking smells of the dishes arranged in the compartment, thus causing an unpleasant olfactory sensation to a person standing in the room in which the appliance is arranged.

[0010] Document AU514079B2 discloses an appliance comprising an oven, a hob and a downdraft hood, wherein the downdraft hood is configured to generate both a suction flow through a suction opening arranged on the hob and a cooling flow in the cavity of the oven door.

[0011] It is known that the area near the cooking compartment of the oven is subject to overheating that may damage the electronic or structural components of the appliance, thereby affecting its reliability. To avoid the aforementioned heating, the appliance described in document AU514079B2 includes an insulating layer surrounding the cooking compartment. A similar insulating layer is shown in document US3756217A.

[0012] Disadvantageously, this insulating layer, in addition to increasing the production costs, also reduces the volume of the cooking compartment of the oven, with the same total footprint of the appliance. In this respect, it should be noted that, in order to ensure adequate thermal insulation, the insulating material must have a high thermal capacity, which can be obtained by means of a large thickness or by using special materials with a high specific heat. However, said special materials have a high cost, which does not justify their use in the appliance field. Therefore, in order to ensure the integrity of the components close to the cooking compartment, a large thickness of the insulating layer is usually used.

[0013] Furthermore, the insulation disadvantageously complicates the design and construction of the appliance because it reduces the internal volume of the appliance for configuring the electronic and structural components of the appliance. Summary of the invention

[0014] Against this background, the technical task at the basis of the present invention is to propose an appliance for cooking dishes which overcomes the above-mentioned disadvantages of the prior art.

[0015] In particular, an object of the invention is to make available an appliance for cooking dishes capable of reducing the disturbances perceived by the user due to its operation, without compromising safety of use.

[0016] More specifically, an object of the present invention is to make available an appliance for cooking dishes capable of eliminating the cooling air flow from the door exiting the oven without exposing the user to risks of scalding.

[0017] Another object of the present invention is to make available an appliance for cooking dishes that, for the same footprint of the appliance, enables the volume of the cooking compartment to be maximized without affecting the reliability of the appliance itself.

[0018] Advantages of the invention

[0019] The reason why the apparatus of the present invention solves the aforementioned technical problems is that the apparatus comprises a downdraft hood having a suction unit, the suction unit being fluidically connected to the cooling cavity of the door, the suction unit being used to draw in a cooling air flow and discharge the air flow through an outlet duct of the downdraft hood.

[0020] In detail, the appliance of the present invention comprises a special duct (hereinafter "second suction duct") configured to fluidically connect the suction unit with the cooling cavity of the door.

[0021] It should be noted that, whether the downdraft hood is installed in filtering or extraction mode, the cooling air flow is not exhausted directly from the oven into the environment in which the appliance is arranged, so as not to create a so-called air curtain and avoid the discomfort experienced by users of traditional appliances.

[0022] Indeed, if the downdraft hood is installed in extraction mode, the cooling flow is exhausted in the external environment of the kitchen, while in filtering mode the outlet duct will be configured to release the extracted air flow through an opening of the kitchen cabinet where the appliance is integrated (for example, near the socket).

[0023] Advantageously, therefore, the appliance of the invention allows the elimination of the cooling air flow exiting the door of the oven without compromising the refrigeration of the door and thus exposing the user to the risk of scalding.

[0024] Furthermore, advantageously, by controlling the intensity of the actuation of the suction unit of the hood as a function of the temperature of the cooking compartment of the oven, it is possible to minimize the amount of energy consumption of the appliance required to cool the door of the oven.

[0025] The appliance of the invention further comprises a third suction duct which is fluidically connected to the suction unit of the downdraft hood and at least partially surrounds the cooking compartment.

[0026] Advantageously, the activation of the suction unit generates an air flow in the third duct which, by flowing in the cooking compartment, thermally insulates the area of ​​the appliance close to the cooking compartment, thereby preventing potential overheating and damage. It should be noted that the third duct is able to ensure effective thermal insulation despite its small footprint, since it continuously transfers heat to the air flow flowing inside it, using convection, which is then exhausted from the appliance. It is therefore clear that the third duct makes it possible to maintain the integrity of the appliance without causing a significant reduction in the volume of the cooking compartment.

[0035] The invention relates to an appliance 1 for cooking dishes, which can be installed in a kitchen for domestic or professional use.

[0036] Reference Figure 1 , the appliance 1 comprises an oven 2, ie a device configured to perform cooking of food in a thermally controlled environment.

[0037] The aforementioned oven 2 has a cooking compartment 20 , which is a cavity suitable for containing the dish to be cooked and delimiting a volume of air temperature-controllable by means of special heating means as known to a person skilled in the art and which will not be further described.

[0038] Reference Figure 2 and Figure 7 The cooking compartment 20 is delimited by a plurality of walls 21, 22, 23, 24 which preferably give it a parallelepiped shape. In detail, the cooking compartment 20 is delimited at the top by an upper wall 21, at the bottom by a lower wall 22, laterally by a pair of opposite side walls 23 and by a rear wall 24.

[0039] According to one aspect, the oven 2 is configured to perform steam cooking of food. To this end, for example, the lower wall 22 of the cooking compartment 20 may have a recessed area suitable for filling with water, or alternatively, the oven 2 may include a special boiler suitable for generating water vapor to be introduced into the cooking compartment 20.

[0040] Reference Figure 1 , the oven 2 has an access opening 25 configured to allow dishes to be introduced into and removed from the cooking compartment 20. The opening 25 must therefore be of a particular size to allow containers for cooking food, such as ovenproof dishes, baking trays and trays, to be easily moved to and from the cooking compartment 3.

[0041] Still refer to Figure 1The opening 25 is defined by a peripheral contour C and is arranged in front of the rear wall 24 of the cooking compartment 20. Preferably, the peripheral contour C comprises an upper edge C1 associated with the upper wall 21, a lower edge C2 associated with the lower wall 22 and a pair of side edges C3 respectively associated with the corresponding side walls 23.

[0042] The oven 2 also includes a door 4 configured to selectively allow access to the cooking compartment 20 .

[0043] In detail, the door 4 can be in the access position ( Figure 1 ) and cooking position ( Figure 2 ), in the access position, leaving the opening 25 of the cooking compartment 20 free in such a way as to allow dishes to be introduced into and removed from the oven 2, and in the cooking position, the door 4 completely blocks the opening 25 of the cooking compartment 20.

[0044] Preferably, but not necessarily, the switching of the door 4 between the access position and the cooking position occurs by a rotation of the door 4 about the hinge axis. However, in an alternative embodiment, this switching may occur by a translational movement. It should be noted that the implementation of the movement of the door between the access position and the cooking position belongs to the capabilities of a person skilled in the art and will not be further described below.

[0045] Reference Figure 2 and Figure 3 , the door 4 includes a cooling cavity 40 configured to be traversed by the cooling air flow F1.

[0046] According to one aspect, the door 4 includes an inner wall 43 that can be associated with the opening 25 of the cooking compartment 20 and an outer wall 44 opposite to the inner wall 43. Preferably, the inner wall 43 and the outer wall 44 are parallel and spaced apart along the thickness direction SS of the door 4, thereby defining the cooling cavity 40. Therefore, the cooling cavity 40 is bounded by the inner wall 43 and the outer wall 42 on opposite sides.

[0047] Reference Figure 2 and Figure 3 The cooling chamber 40 of the door 4 includes an inlet opening 41 and an outlet opening 42 .

[0048] The inlet opening 41 is configured to allow the introduction of a cooling air flow 40 into the cooling cavity 40. Thus, the inlet opening 41 places the cooling cavity 40 in fluid dynamic communication with the environment outside the oven 2.

[0049] Preferably, according to Figure 2 As shown, an inlet opening 41 is obtained at the lower edge S1 of the door 4 .

[0050] It should be noted that the lower edge S1 of the door 4 is arranged at the lower edge C1 of the opening 25 of the cooking compartment 2 when the door is in the cooking configuration.

[0051] The outlet opening 42 is configured to allow discharge of the cooling air flow F1 introduced into the cooling chamber 40 by means of the inlet opening 41 .

[0052] Preferably, according to Figure 2 As shown, the outlet opening 42 is obtained at the upper edge S2 of the door 4, opposite to the aforementioned lower edge S1. Therefore, preferably, the inlet opening 41 and the outlet opening 42 are arranged at opposite ends of the door 4.

[0053] The cooling flow F1 then passes through the cooling chamber 40 from the inlet opening 41 to the outlet opening 42 , exchanging heat with the wall of the door 4 .

[0054] Thus, when the cooking compartment 20 of the oven 2 is brought to temperature, the cooling air flow F1 allows the temperature of the door 4 , and in particular the temperature of the outer wall 44 , to be reduced.

[0055] It is worth mentioning that, even if not shown in the present description, the oven 2 comprises all typical components of an oven, such as a ventilation system for the cooking compartment or a support grid adjustable at different height levels.

[0056] Reference Figure 1 The appliance 1 of the present specification further comprises a stove rack 5 arranged above the oven 2 along the vertical direction VV.

[0057] It is worth noting that, in the context of the present invention, hob 5 means a device having multiple cooking zones, the cooking zones being suitable for statically receiving a pot containing a dish to be heated. For the purposes of the present invention, the hob can be induction, electric or hybrid (i.e., induction or electric and gas).

[0058] The hob 5 comprises one or more suction openings 50, through which a suction effect can be created of the cooking steam from the pot containing the dish to be heated. Figure 7 The suction air flow is represented by F3.

[0059] It should be noted that according to Figure 6 and Figure 7 As shown, the suction opening 50 is of the through-type, ie the suction opening 50 passes through the entire thickness of the plate 51 defining the resting surface of the hob 5 .

[0060] exist Figure 1 In the embodiment of the present invention, the hob 5 has a pair of suction openings 50 arranged at opposite peripheral areas of the plate 51. In an alternative embodiment, one or more suction openings may be arranged at least partially at a central area of ​​the plate 51 defining the resting surface of the hob 5.

[0061] According to one aspect, the appliance 1 comprises a closing element 11 associated with a corresponding suction opening 50 of the hob 5. In detail, the closing element 11 can be switched between a closed position and an open position, in which the closing element 11 blocks the suction opening 50 to prevent the passage of liquids or solids ( Figure 6 ), in the open position, the closing element 11 leaves the associated suction opening 50 at least partially free ( Figure 7 ).

[0062] exist Figure 6 and Figure 7 In the embodiment shown, the closing element 11 comprises a movable wall 110 specifically dimensioned to completely block the suction opening 50 of the hob 5 and movement means 111 (electronically or mechanically actuated) configured to move said movable wall 110 between a closed position and an open position.

[0063] The appliance 1 of the invention further comprises a downdraft hood 6, ie a hood for extracting cooking fumes integrated in the hob.

[0064] Reference Figure 6 and Figure 7 The downdraft hood 6 comprises a suction unit 60 configured to generate a suction flow F3 suitable for carrying away steam generated by a pot arranged on the hob and, as explained in detail below, generating a cooling air flow F1 for the door 4 .

[0065] It is worth noting that the suction unit 60 includes at least one impeller driven to rotate by a motor to generate the above-mentioned suction flow.

[0066] According to one aspect, the operating intensity of the suction unit 60 is modulated to generate a variable volume flow suction flow. Preferably, the suction unit 6 is configured to generate a flow equal to 1300 m 3 / h maximum volume flow rate.

[0067] According to one aspect, the downdraft hood 6 comprises a box-shaped body 12 defining a suction compartment 120, in which a suction unit 60 is located. In use, the suction unit 60 is configured to generate a low air pressure in the suction compartment. In the embodiment shown in the drawings, the box-shaped body 12 is arranged below the oven 2 along the vertical direction VV.

[0068] Reference Figure 6 and Figure 7 The downdraft hood 6 also includes a first suction duct 7 and an outlet duct 8.

[0069] In detail, the first suction duct 7 is configured to fluidically connect the suction unit 60 with the suction opening 50 of the hob 5 .

[0070] In use, according to Figure 6 and Figure 7 As shown, the suction unit 60 draws in the air flows F1 , F2 , F3 via the first suction duct 7 and discharges them via the outlet duct 8 .

[0071] In the embodiment shown in the drawings, the suction duct 7 and the outlet duct 8 are placed upstream and downstream of the box-like body 12 , respectively, so that the low air pressure in the suction compartment 120 causes a suction effect in the suction duct 7 .

[0072] It is worth noting that the downdraft hood 6 can be installed in either a suction mode or a filtering mode.

[0073] In suction mode, the outlet duct 8 is fluidically connected to the external environment in which the appliance 1 is arranged.

[0074] While in filtering mode, the outlet duct 8 is configured to release the sucked air flow in a special compartment of the cabinet in which the appliance 1 is integrated. In this respect, it should be noted that the air flow exiting from the outlet duct 8 is not released directly into the environment of the kitchen, so the user is not exposed to any air flow that could cause any disturbance to him.

[0075] Still refer to Figure 6 and Figure 7 The first suction duct 7 preferably extends at least partially in the vertical direction VV near one side wall 23 of the cooking compartment between an upper portion 71 associated with the suction opening 50 of the hob 5 and a lower portion 72 associated with the suction unit 60. Preferably, the lower portion 72 is connected to the box-like body 12 in a fluid communication with the suction compartment 120.

[0076] In the embodiment shown in the drawings, there are two suction ducts 7 , one for each suction opening, and the suction ducts are arranged on opposite sides of the cooking chamber 20 .

[0077] According to a characteristic aspect of the invention, the appliance 1 comprises a second suction duct 9 configured to fluidically connect the suction unit 60 of the downdraft hood 6 with the cooling cavity 40 of the door 4 .

[0078] It should be noted that the second suction duct 9 allows the aforementioned cooling air flow F1 to be sucked through the cavity 40 and discharged from the outlet duct 8 of the downdraft hood 6. The path followed by the cooling air flow F1 is Figures 2 to 6 and described thoroughly below.

[0079] Reference Figure 2 and Figure 3Preferably, the hob 5 is spaced apart from the upper wall 21 of the cooking compartment 20 along the vertical direction VV, and the second suction duct 9 at least partially extends between them. In other words, the second suction duct 9 is installed between the hob 5 and the upper wall 21 of the cooking compartment 20 along the vertical direction VV.

[0080] Advantageously, said arrangement of the second suction duct 9 also allows cooling of the region of the appliance 1 arranged near the upper wall 21 of the cooking chamber 20 , apart from the door 4 .

[0081] Reference Figure 4 and Figure 5 The second suction duct 9 extends along the depth direction XX from a front portion 1 a of the appliance 1 located near the door 4 to a rear portion 1 b of the appliance 1 opposite to the front portion 1 a .

[0082] When the door 4 blocks access to the cooking compartment, ie when the door 4 is in the cooking position, the second suction duct 9 is fluidically connected with the outlet opening 42 of the cavity 40 .

[0083] according to Figure 3 In the aspect shown, the second suction duct 9 comprises a slit 90 arranged near the front 1a of the appliance 1 and facing the door 4. The slit 90 is arranged at the upper edge S2 of the door 4 in fluid dynamic communication with the outlet opening 42 of the cavity 40 when the door 4 is in the cooking position.

[0084] In view of the above, it should be noted that the low air pressure in the second suction duct 9 generates a cooling air flow F1, which, after entering the cavity 40 through the inlet opening 41, passes through the cavity 40, the outlet opening 42, the gap 90 and the suction duct 9 in sequence, then reaches the suction unit 6 and is discharged by the outlet duct 8.

[0085] Preferably, the second suction duct 9 is fluidically connected to the suction unit 60 via the first suction duct 7. Thus, the low air pressure caused by the suction unit 60 in the first suction duct 7 also affects the second suction duct 9, thus generating a cooling flow F1 of the door 4.

[0086] Reference Figures 4 to 5 The second suction duct 9 is fluidically connected to the first suction duct 7 upstream of the suction unit 60 and downstream of the suction opening 50 of the hob 5 , ie between the upper part 71 and the lower part 72 of the first suction duct 7 .

[0087] In such a configuration, the suction compartment 120 is in fluid dynamic communication with the second suction duct 9 via the first suction duct 7 .

[0088] according to Figure 4 and Figure 5In the aspect shown, the second suction duct 9 extends in the width direction YY and is connected to the first suction duct 7 by means of a special joining opening 97 .

[0089] It is worth noting that the width direction YY forms a Cartesian triple with the depth direction XX and the vertical direction VV. Therefore, the depth direction XX, the width direction YY and the vertical direction VV are oriented orthogonally relative to each other, that is, they realize a three-orthogonal Cartesian reference system.

[0090] Therefore, the cooling flow F1 that has reached the second suction duct 9 through the slit 90 will simultaneously move toward the rear portion 1b of the device 1 along the depth direction XX and toward the engaging opening 97 along the width direction YY. The path followed by the cooling flow F1 can be determined by Figure 4 and Figure 5 Observe the dotted arrow marked F1 in the figure.

[0091] It is worth noting that in an alternative embodiment (not shown in the drawings), the first and second suction ducts 9 can be directly and independently connected to the suction unit 60, however, this will endanger an increase in the footprint of the appliance or a reduction in the capacity of the cooking compartment 20.

[0092] Reference Figure 2 , the appliance 1 comprises a third suction duct 10 which is fluidically connected to the suction unit 60 of the downdraft hood 6 and at least partially surrounds the cooking compartment 20 .

[0093] Said third suction duct 10 is configured to be traversed by an air flow F2 different from the cooling flow F1 when the suction unit 60 is activated.

[0094] It should be noted that the air flow F2 through the third suction duct 10 allows cooling of the area of ​​the appliance 1 close to the cooking compartment 20, thereby preventing potential overheating.

[0095] Still refer to Figure 2 Preferably, the third suction duct 10 extends at least partially in a direction transverse to the vertical direction VV near the lower wall 22 of the cooking compartment 20. In other words, the third suction duct 10 at least partially surrounds the lower wall 22 of the cooking compartment 20.

[0096] According to a possible embodiment, the third suction duct 10 has a first section 10a extending along the depth direction XX from the front part 1a to the rear part 1b of the device 1 .

[0097] In detail, the third suction duct 10 has a suction opening 100 arranged in the front portion 1 a of the appliance 1 near the door 4 , configured to allow the introduction of an air flow F2 in the third suction duct 10 .

[0098] Still refer to Figure 2 Preferably, the third suction duct 10 has a second section 10 b which is connected in series to the first section 10 a and is arranged in a rear part 1 b of the appliance 1 in the vicinity of the rear wall 24 of the cooking compartment 20 .

[0099] According to a possible embodiment, the third suction duct 10 is fluidically connected to the first suction duct 7 upstream of the suction unit 60 and downstream of the suction opening 50 , ie between the upper part 71 and the lower part 72 of the first suction duct 7 .

[0100] Reference Figure 4 and Figure 5 , the air flow F2 reaches the upper wall 21, and by flowing over the top of the upper wall 21, will move toward the front portion 1a of the appliance along the depth direction XX and toward the engagement opening 97 along the width direction YY. This path of the air flow F2 can be Figure 4 and Figure 5 Observe the solid arrow marked F2 in the figure.

[0101] It is worth noting that the air flow F2 will merge with the air flow F1 by entering the first suction duct 7 .

[0102] exist Figure 4 and Figure 5 In the embodiment of the cooking chamber 20, preferably, the appliance 1 comprises a partition 13, which is arranged on the upper wall 21 of the cooking chamber 20 and is suitable for keeping the air flows F1 and F2 separated when the air flows F1 and F2 flow on the upper wall 21. In detail, the partition 13 is installed between the upper wall 21 and the hob 5 along the vertical direction VV and extends parallel to the width direction YY so as to prevent the air flows F1 and F2 moving in opposite directions along the depth direction XX from meeting each other according to the above.

[0103] Advantageously, this allows preventing the formation of noisy turbulent movements above the upper wall 21 of the cooking compartment 20. Furthermore, it prevents the formation of stagnant areas of the air flow and the subsequent heating.

[0104] Preferably, the appliance 1 comprises one or more filters (not shown in the drawings) arranged upstream of the suction unit 60 of the downdraft hood 6 in at least one of the first, second, 9 and third suction ducts 10 .

[0105] In one embodiment, the appliance 1 comprises a grease and / or odour filter in the first suction duct 7 between the upper part 71 and the lower part 72 .

[0106] Furthermore, the appliance 1 can comprise a grease filter arranged in the second suction duct 9 downstream of the slot 90 .

[0107] According to one aspect, the appliance 1 comprises an electronic control unit 14 placed in signal communication with the hob 5, the oven 2 and the extraction hood 6 to control the operating modes thereof.

[0108] The appliance 1 of the present specification further comprises a control interface 15 placed in signal communication with the control unit 14. The user interacts with the control interface 15 to determine the operating mode of the appliance 1, in particular the hob 5, oven 2 and extraction hood 6.

[0109] Obviously, in order to meet occasional and special needs, those skilled in the art may make various modifications and variations to the above-mentioned structure, and such modifications and variations are also all included in the scope of the present invention defined by the appended claims.
