Description

Technical Field

[0001] The present invention relates to a cooking hob as described in the preamble of claim 1.

[0002] In particular, but not exclusively, the present invention relates to a cooking appliance integrated with a cover of the type commercially known as a retractable cover or a downward ventilation cover. Background Technology

[0003] Hoods for home environments are now installed in all household kitchens because their usefulness in extracting gaseous forms generated during food preparation (i.e., steam from cooking) is now undisputed. Therefore, having hoods for home environments that effectively eliminate cooking steam generated during the food preparation stage and handle it properly is becoming increasingly important.

[0004] For this purpose, a hood has been developed that can draw air from the home and exhaust it outside the home through a suction unit, as well as filter it and reintroduce it into the home environment.

[0005] Among the various hoods available on the market, there are also so-called downdraft hoods, which are typically integrated into the cooktop or, alternatively, into the top of a kitchen cabinet. In particular, downdraft hoods are configured to generate a downward airflow that is faster than the rising velocity of cooking steam, causing the steam to be drawn downwards and vertically toward the cooktop itself.

[0006] Examples of these downward ventilation hoods are shown in the same applicant’s patent IT102016000034820, particularly examples of downward ventilation hoods integrated into cooking cooktops.

[0007] This document discloses a cooking appliance including a support member. The support member has an upper surface and a lower surface. On the upper surface, a cooking zone is defined to house a heating element. The support member is provided with a suction opening for drawing out cooking fumes. The cooking appliance also includes a suction duct in fluid communication with the suction opening. A centrifugal fan is in fluid communication with the suction opening and specifically has an inlet gap in fluid communication with the suction duct. The fan exhausts fumes through an outlet duct. A motor is associated with the centrifugal fan to rotate it.

[0008] To handle cooking fumes, existing downdraft hoods provide a first filter, typically consisting of a metal grid, adapted to promote the condensation of suspended liquid or semi-liquid particles (such as grease) in the cooking fumes. This first filter can be coupled to a second filter adapted to absorb odors from the cooking fumes and can include one or more filter elements, typically with activated carbon.

[0009] Specifically, these filters can be configured immediately downstream of the suction opening obtained on the cooking stove and suspended inside the suction channel. In this way, by sequentially encountering the first and second filters, the inhaled cooking fumes release liquid or semi-liquid cooking residues, such as water, oil, grease, etc., that have passed through the suction opening. Such substances can settle at the bottom of the suction channel, which can be emptied by a corresponding removal device or alternatively in a removable collection container.

[0010] The downside is that, during extraction, the suspended filter used for cooking fumes is not effective at handling cooking fumes once they are extracted and directed into the extraction channel.

[0011] Furthermore, suspended filters cause uneven distribution of drawn-out cooking fumes, leading not only to pressure drop and reduced extraction efficiency, but also to the dispersion of residues from improperly filtered cooking fumes on the walls of the extraction channel and inside the impeller. This necessitates more frequent cleaning and maintenance, and increases energy costs associated with extraction.

[0012] Document WO2012 / 146237 describes a cooking appliance in which a suction pipe has a base surface with a lowered central region defining a "basin" for collecting liquids. The cooking appliance also includes a filter, the end of which is inserted into the basin.

[0013] It should be noted that in the cooking appliances described in WO2012 / 146237, it is the geometry of the central region of the base surface of the suction pipe that allows liquid to be retained, rather than the type of connection formed with the filter. To confirm this, it should be noted that even with a removed filter, the lowered central region of the base surface is capable of retaining liquid. Therefore, document WO2012 / 146237 does not explicitly or implicitly teach a fluid-tight coupling between the filter and the base surface of the suction pipe. Summary of the Invention

[0014] The object of this invention is to overcome the shortcomings described with reference to the prior art, and in particular to provide a cooking stove capable of effectively filtering cooking fumes. Another object of this invention is to provide a cooking stove capable of improving extraction efficiency during the filtering of extracted cooking fumes.

[0015] These and other objectives are achieved by a cooking appliance according to any one of the appended claims.

[0016] Advantageously, the cooking cooker of the present invention allows full utilization of the available space inside the suction channel to increase the contact surface between the sucked smoke and the filter. In this way, the cooking cooker of the present invention enables the removal of a greater amount of residue present in cooking fumes.

[0017] Advantageously, the cooking appliance of the present invention allows drawn and properly filtered cooking fumes to be directed toward the impeller for subsequent ejection, thereby reducing pressure drop.

[0018] Advantageously, the cooking cooktop of the present invention makes it possible to reduce cleaning and maintenance rates and to promote and accelerate the cleaning of the cooking cooktop itself.

[0019] Other features and advantages of the present invention will become apparent to those skilled in the art from the following detailed disclosure of exemplary embodiments of the invention. Attached Figure Description

[0026] Figure 6 A cross-sectional view of a portion of a filter according to another embodiment of the present invention is shown. Detailed Implementation

[0027] Even if not explicitly stated, the features described with reference to a particular embodiment should be understood as additional features to those described with reference to other embodiments and / or interchangeable with those described with reference to other embodiments.

[0028] Referring to the accompanying drawings, 1 refers to the cooking stove according to the present invention.

[0029] The cooking cooktop 1 includes a support element 10 having an upper surface 11 and a lower surface 12. Specifically, when the cooking cooktop 1 is installed, the upper surface 11 of the support element 10 is the side that is visible or can be seen by the user, while the lower surface 12 is the side that is hidden from the user's view, for example, because it is recessed into a kitchen cabinet.

[0030] According to one aspect, the support element 10 thus defines a suitable volume that can accommodate the necessary components for performing the dish control and heating / cooking functions, as well as the extraction of cooking steam. Additional electronic components can be housed in a compartment associated with the support element located on the lower surface 12 side.

[0031] In one embodiment, the upper surface 11 is implemented as a plate of glass or a material with similar properties (not shown).

[0032] According to a preferred aspect, the upper surface 11 and the lower surface 12 are both implemented as flat and parallel surfaces and opposite to each other.

[0033] The cooking appliance includes at least one cooking zone 13, which is configured to house one or more heating elements (not shown) on its upper surface 11.

[0034] Special Reference Figure 2 Multiple cooking zones 13 can be identified on the upper surface 11. In this case, the cooking zones 13 are appropriately distributed on the upper surface 11 of the support element 10, and in particular, in the case of a resistance heating element, the cooking zones 13 are configured to radiate heat, or in the case of an induction heating element, the cooking zones 13 are configured to generate induction heat within a special cooking vessel.

[0035] Preferably, there are four cooking zones 13, but different alternative implementations with more or fewer cooking zones 13 are possible.

[0036] According to a preferred embodiment, the support element 10 also has a cavity 14 extending substantially between the upper surface 11 and the lower surface 12. Preferably, the cavity 14 is located in the center of gravity relative to the cooking zone 13. In the illustrated embodiment, the cavity 14 extends from the upper surface 11 to the vicinity of the lower surface 12.

[0037] The cooking stove 1 includes a suction opening 20 for drawing out cooking fumes. Preferably, the suction opening 20 is located in the cavity 14. According to a preferred embodiment, the suction opening 20 is circular in shape and is protected by a grille or movable element (not shown). Preferably, the grille or movable element is removable to allow for maintenance operations.

[0038] The grille and movable elements have safety features because they prevent foreign objects from being introduced into the suction opening 20.

[0039] The cooking appliance 1 also includes a suction pipe 30 that is in fluid communication with the suction opening 20.

[0040] The suction conduit 30 has a base wall 31 spaced apart from the lower surface 12 along a transversely spaced direction XX (preferably perpendicular to the lower surface 12). The suction conduit 30 also includes a side wall 32 extending between the base wall 31 and the lower surface 12.

[0041] The cooking appliance 1 also includes a suction device (not shown) associated with the suction opening 20 and preferably disposed inside the suction pipe 30. In particular, the suction device is configured to draw in cooking fumes through the suction opening 20 and the suction pipe 30 and then exhaust them.

[0042] According to a preferred embodiment, the suction device includes a centrifugal impeller having an inlet opening and a transport screw. The inlet opening is in fluid communication with a volume defined by the suction conduit 30. Preferably, the suction device also includes a motor associated with the centrifugal impeller to rotate it. In particular, the motor is mechanically coupled to the centrifugal impeller, for example, through a direct mechanical connection between the motor's rotor and the hub of the centrifugal impeller.

[0043] More specifically, the cooking appliance 1 includes connecting devices (not shown) that function between the motor, support element, and suction pipe, particularly at the lower surface 12. These connecting devices may include a plurality of screws (not shown) and an equal number of holes (not shown) obtained on the lower surface 12 of the support element 10. In alternative embodiments, the screws may be replaced by any similar fastening element known to those skilled in the art (e.g., by way of example, rivets, welding, glue, or others).

[0044] According to the preferred embodiment, reference is also made to Figure 1 and Figure 2 The cooking appliance 1 includes a filter 50, which is configured to filter the drawn-in cooking fumes.

[0045] In a preferred embodiment, the filter 50 is at least partially disposed inside the suction conduit 30 in a removable manner and can be removed from the cavity 14 to allow the user to perform normal maintenance operations, such as cleaning or replacement.

[0046] According to one aspect, during removal / insertion, the filter 50 passes through the suction opening 20.

[0047] Preferably, the filter 50 is at least partially disposed in the cavity 14, and the remainder is disposed in the suction pipe 30.

[0048] The filter 50 extends between a first end 51 and a second end 52, the first end being configured to engage the support element 10 at the suction opening 20, and the second end being configured to fluid-tightly engage with the base wall 31.

[0049] Specifically, the filter 50 extends between opposite ends 51 and 52 along a development direction AA that is substantially parallel to the spacing direction XX. In this way, the first end 51 can be identified as the portion closest to the suction opening 20, i.e., it can be identified as the upper part, while the second end 52 can be identified as the portion closest to the base 31, i.e., it can be identified as the lower part.

[0050] According to a preferred embodiment, the filter 50 is axially asymmetrical, and its axis of symmetry extends between the first end 51 and the second end 52. Therefore, in use, the axis of symmetry is perpendicular to or orthogonal to the floor plane.

[0051] In other words, in a preferred embodiment, the filter 50 is shaped as a hollow cylindrical body extending along the spacing direction XX.

[0052] As expected, the filter 50 is shaped to provide a fluid tightness at the end 52 itself between the base 31 and the lower end 52. This feature maximizes the filter surface because the gap between the lower surface 12 and the base wall 31 is fully utilized (i.e., over its entire distance). Furthermore, any liquid overflowing through the opening 20 is prevented from flowing downstream of the filter 50.

[0053] Specifically, filter 50 includes one or more grease filters 53 and one or more odor filters 54 to filter inhaled cooking fumes and reduce odor dispersion.

[0054] It should be noted that the grease filter 53 is made of one or more stretched metal grids or other materials with similar properties, while the odor filter 54 is made of a porous material capable of filtering inhaled cooking fumes.

[0055] According to an advantageous aspect, the grease filter 53 and the odor filter 54 are configured in series, that is, the drawn-in vapor first passes through the grease filter 53 and then through the odor filter 54.

[0056] In a preferred embodiment, the grease filter 53 and the odor filter 54 are asymmetrical along the XX-axis and are particularly shaped as hollow cylindrical bodies.

[0057] According to a specific aspect of this disclosure, the grease filter 53 and the odor filter 54 are cylindrical bodies without a base surface, i.e., they have neither an upper base nor a lower base. In other words, the grease filter 53 and the odor filter 54 are formed as hollow cylindrical bodies without two base surfaces. In other words, the grease filter 53 and the odor filter 54 have a tubular shape, i.e., a cylindrical shape with openings at the top and bottom (i.e., openings at their base ends).

[0058] According to a preferred embodiment, the filter 50 includes a first filter retainer frame 70, which defines a first filter channel 71 extending between a first end 51 and a second end 52.

[0059] The filter channel 71 has a first filter opening 72 in fluid communication with the suction opening 20, a second filter opening 73 opposite to it, and a first filter wall 74 defining the opposing filter openings 72 and 73 and configured to allow fluid communication between the suction opening 20 and the suction pipe 30.

[0060] The first filter retainer frame 70 is configured to house one or more grease filters 53 that define the first filter wall 74.

[0061] Preferably, the first filter holder frame 70 includes a base element 75 and a head element 76, which can be coupled to house and hold one or more grease filters 53 between them.

[0062] Specifically, the base element 75 and the head element 76 include opposing housings 77 configured to receive and hold opposite ends 53a, 53b of one or more grease filters 53.

[0063] It should be noted that the base element 75 and the head element 76 define the second filter opening 73 and the first filter opening 72, respectively.

[0064] According to a preferred embodiment, the filter 50 includes a second filter retainer frame 80 defining a second filter channel 81 extending between a first end 51 and a second end 52. The second filter channel 81 has a third filter opening 82 in fluid communication with the suction opening 20, an opposite fourth filter opening 83 blocked by a base wall 31, and a second filter wall 84 defining the associated filter openings 82, 83 and configured to allow fluid communication between the first filter channel 74 and the suction conduit 30.

[0065] Specifically, the fourth filter opening 83 is closed by the base wall 31, forcing the cooking fumes drawn from the suction opening 20 to pass in series through the first filter wall 74 and the second filter wall 84.

[0066] Advantageously, the filter 50 allows for proper filtration of drawn-out cooking fumes using the entire extension of the first filter wall 74 and the second filter wall 84.

[0067] It should be noted that the second filter retainer frame 80 is configured to house the one or more odor filters 54 that define the second filter wall 84.

[0068] Preferably, the second filter holder frame 80 includes an inner frame 85 and an outer frame 86, the outer frame being connectable to the inner frame 85 to hold the one or more odor filters 54. According to a preferred embodiment, the outer frame 86 surrounds the inner frame 85. According to one aspect, the outer frame 86 may be divided into multiple sections, which may be connected to the inner frame 85 by a coupling device 88 such as screws and / or an interlocking system.

[0069] Specifically, the inner frame 85 and the outer frame 86 define a second receiving portion 87 between them, which is configured to receive the one or more odor filters 54. It should be noted that the inner frame 85 defines a fourth filter opening 83 and a third filter opening 82 at opposite ends 85a and 85b, respectively.

[0070] Preferably, the first filter retainer frame 70 is configured to be disposed inside the second filter retainer frame 80, particularly inside the second filter channel 81.

[0071] More preferably, when the first filter holder frame 70 is inserted into the second filter channel 81 of the second filter holder frame 80, the first filter channel 71 and the second filter channel 81 are coaxial.

[0072] According to a preferred embodiment, the filter 50 includes a gasket element 60 at the second end 52, which preferably surrounds the second filter opening 83.

[0073] like Figure 1 As shown, the gasket element 60 is configured to abut against the base wall 31 to form a sealing connection with the base wall 31. In use, when the gasket 60 abuts against the base 31, the second filter opening 83 is hermetically sealed by the base wall 31.

[0074] Advantageously, since the filter n50 is sealed as a whole to the base wall 31, the gasket 60 allows the drawn-in vapor to be delivered to the first filter wall 74 and the second filter wall 84.

[0075] According to a preferred embodiment, the gasket 60 is associated with the second filter retainer frame 80.

[0076] Specifically, the inner frame 85 includes a seat 87 at end 85b on the side of the second end 53 for receiving a gasket 60 that at least partially protrudes from the seat 87. In this way, once the filter 50 is positioned inside the suction channel 30, it engages the base wall 31 through the gasket 60, thereby ensuring its airtightness and thus preventing the passage of drawn smoke, and thus directing it toward the filter openings 74, 84.

[0077] Alternatively, the washer 60 may be disposed in a corresponding seat formed in the base wall 31 and configured to receive and engage the filter 50 at the second end 52.

[0078] According to one aspect, the filter 50 includes a first coupling member 90 configured to removably secure a first filter retainer frame 70 and a second filter retainer frame 80 between the first coupling member.

[0079] Preferably, the first connecting member 90 provides shape coupling between the first filter holder frame 70 and the second filter holder frame 80. Specifically, the inner frame 85 at end 85a of the first end 51 is shaped to form a shape coupling with the head element 75 of the first frame 70. More preferably, the inner frame 85 at end 85a and the head element 75 have an inverted truncated conical shape to facilitate the extraction of cooking fumes.

[0080] Alternatively or in combination, the first connecting member 90 includes a first connecting element and a second connecting element, which are respectively defined on the first filter holder frame 70 and the second filter holder frame 80, and are configured to be interlocked with each other after movement along the spacing direction XX and / or after rotation about the spacing direction XX.

[0081] Alternatively or in combination, the first connecting member 90 may include a third connecting element configured to hold the first connecting element and the second connecting element together, for example, by a screw and nut threaded connection.

[0082] According to another aspect, the filter 50 includes a second connecting member 100 configured to removably secure the first filter holder frame 70 or the second filter holder 80 to the support element 10.

[0083] Preferably, the second connecting member 100 provides a form connection between the support element 10 and the first end 51 of the filter 50.

[0084] Specifically, the first end 51 is shaped to create a shape connection with the cavity 14.

[0085] Alternatively, the second connecting member 100 includes a first fixing element and a second fixing element, respectively defined on the support element 10 and the filter 50, and selectively defined on either the first filter holder frame or the second filter holder frame. The fixing elements are configured to interlock with each other after movement along the spacing direction XX and / or after rotation about the spacing direction XX. Alternatively, the second connecting member 100 may include a third fixing element configured to hold the first and second fixing elements to each other, for example, by a screw-nut threaded connection.

[0086] According to the features of this disclosure, a fluid-tight sealing gasket 60 defines a first collection volume 120, which is designed to at least partially collect liquid flowing through and filtered through the suction opening 20 itself.

[0087] In particular, such liquids can be collected in the first collection volume 120 as they are drawn in with the cooking fumes by the suction device, or they can be drawn in by the suction device (or not drawn in at all) after they have overflowed from, for example, a container dedicated to cooking food.

[0088] For example, the liquid can be water, water vapor, and / or water mixed with oil and / or grease.

[0089] The first collection volume 120 is configured to hold a predetermined amount of liquid, then provide an overflow outside the second filter channel 81, and provide liquid distribution inside the suction pipe 30 on the base wall 31.

[0090] Preferably, the suction conduit 30 includes a discharge component (not shown) that allows liquid overflow from the suction conduit. These discharge components may include orifices formed in the suction conduit and selectively removable closure elements for discharging accumulated liquid.

[0091] Specifically, the first collection volume 120 is defined by a filter 50, which defines a collection barrier 121 extending from the base wall 31 and from a portion 122 of the base wall 31 surrounded by the filter 50. It should be noted that the collection barrier 121 is defined by a base element 75. Alternatively, the collection barrier 121 is defined by a combination of an inner frame 85 and an outer frame 86 at end 85b.

[0092] According to an alternative embodiment of the foregoing embodiments, and in combination with the foregoing embodiments, the first filter holder frame 70 includes a collection bucket 110 configured to collect liquid present in the drawn cooking fumes. The collection bucket 110 is held to the first filter holder frame 70 at a second opening 73.

[0093] Preferably, the collection bin 110 includes a collection tray 111 and a receiving wall 112 extending from the collection tray 112 and spaced apart from the first filter retainer frame 70 to define a collection area 113 within the first filter channel 74 and the second filter channel 84.

[0094] The collection area 113 is located outside the collection tank 110. Specifically, the receiving wall 112 has a perforated connecting edge 114 configured to removably connect the collection tank 110 to the first filter retainer frame 70 and to drain liquid from the collection tank 110 into the collection area 113.

[0095] Specifically, the connecting edge 114 includes a plurality of holes spaced circumferentially apart from each other.

[0096] It should be noted that the collection area 113 is confined within the first collection volume 120. Liquid collected inside the collection tank 110 overflows into the collection area 113 once it passes through the containment wall 112. The filling of the collection area substantially corresponds to the filling of the collection volume 120, and then overflows outside the filter 50 on the base wall 31 as previously described.

[0097] Obviously, those skilled in the art can make many modifications and variations to the above-described structure to meet occasional and specific needs. All such modifications and variations are included within the scope of protection of the invention as defined by the appended claims.
