Description

[0001] A COOKER HOOD HAVING A LOWER BODY WITH A FRONT PANEL

[0002] TECHNICAL FIELD

[0003] This invention relates to a cooker hood comprising a lower body configured to draw in air from a cooking area and located on a side closer to the cooking area, a body frame defining a periphery of the lower body, a front panel on which at least one control element is provided, configured to allow at least the control of air suction levels, and at least one attachment system for attaching the front panel to the body frame.

[0004] STATE OF THE ART

[0005] Cooker hoods are devices that prevent the smoke and odour generated in a cooking area, such as a hob or a built-in hob (cooktop), from spreading into the indoor space by suctioning the smoke and odour and directing them to a chimney or an air duct. Cooker hoods have a front panel, which is essentially in the form of a plate and made of a glassceramic material. The front panel is the part of the cooker hood that has control elements configured to allow at least the control of air suction levels. The front panel is connected to a front frame portion made of a metal material. Metal brackets are generally used for this connection. The production of metal brackets is a process that is both timeconsuming and costly, as it requires a series of operations such as laser cutting and bending. In particular, it is quite difficult to correctly align and centre the metal brackets with the front panel made of glass material. These centring problems experienced during the production process can negatively affect the aesthetic appearance and functionality of the front panel.

[0006] CN203549959U discloses a fixing device for the panel glass of a cooker hood. The fixing device consists of a concave fixing device arranged on the cooker hood body and a convexfixing device arranged on the panel glass and correspondingto the concave fixing device. Here, the concave fixing device comprises a fixing plate having a hole, a concave fixing knob penetrating from one side of the hole, and a limit knob arranged on the other side of the hole and corresponding to the concave fixing knob. The fixing plate is a bent plate with a recessed middle part, and the hole is formed in the recessed middle part. Mounting holes are formed at both ends of the fixing plate. The convex fixing device comprises a mounting plate having fixing holes and a convex fixing knob arranged on the mounting plate. Thus, when the concave fixing device and the convex fixing device are assembled, since the mounting plate is located in the recessed middle part, the assembly is neat, the assembly gap is not obvious, and the disassembly process is facilitated.

[0007] BRIEF DESCRIPTION OF THE INVENTION

[0008] The object of the present invention is to provide a cooker hood whose front panel is easy to centre on the lower body, simple to assemble, and has a low production cost, the object is achieved, according to the invention, by a cooker hood having a lower body including a front panel with the features of claims 1 to 14.

[0009] In orderto achieve the said object, the invention is a cooker hood comprising a lower body configured to draw in air from a cooking area and located on a side closer to the cooking area, a body frame defining a periphery of the lower body, a front panel on which at least one control element is provided, configured to allow at least the control of air suction levels, and at least one attachment system for attaching the front panel to the body frame. The attachment system in the cooker hood comprises a centring element connected to a panel rear face facing the body frame and configured to pass at least partially through the body frame, and a clamping element provided on a side opposite to the side where the front panel is located, corresponding to the centring element, and configured to be guided towards a frame inner face by the centring element when rotated in a direction of rotation to be connected to the centring element. In this way, the front panel is prevented from shifting on its axes, and it is easily centred on the body frame. Thus, the front panel is positioned on the body frame in an aligned manner, and an improved aesthetic appearance is obtained. Furthermore, after the centring of the front panel, its attachment to the body frame is achieved in a simple manner, and assembly accuracy is increased. Thanks to the simple attachment process, production times are reduced, and consequently, production costs are lowered. The cooking area mentioned herein may be a cooking appliance, particularly a hob, for example, a countertop hob or a built-in hob. Said cooking appliance may also be an oven, particularly a freestanding oven. The front panel mentioned herein may be a control panel having control elements thereon. The control elements may be knob-like elements controlled manually, as well as a touch-sensitive button developed to be sensitive to a touch, or a push button. The front panel may be provided in the form of a substantially planar plate. The front panel may be made of a glass-ceramic material. The body frame mentioned herein refers to a closed geometric structure configured in the form of a frame. Said body frame may have any closed geometric shape, for example, a substantially rectangle-like shape. The body frame may be made of a metal material. The centring element mentioned herein may be any structure such as an extension, a protrusion, or a projection that can provide for the centring of the front panel on the body frame. The clamping element mentioned herein may be an element that clamps the front panel by pulling it so as to restrict its movement in all directions and thus attaches it to the body frame. The centring element and the clamping element herein are shaped and sized in conformity with each other. The centring element and the clamping element herein may be provided in a substantially hollow cylindrical structure, compatible with and complementary to each other.

[0010] In a possible embodiment of the invention, the body frame comprises a front frame portion having a front wall provided to be in a plane substantially parallel to the front panel, and a receiving opening is provided on the front wall corresponding to the centring element. Thus, the front wall on which the front panel can rest and the centring of the front panel on the front wall are provided. Accordingly, the front panel is aligned with full accuracy on the front wall, independently of the front panel dimensions. Here, the front panel may have width and length dimensions in the width and height directions, respectively, that are different from those of the front wall. Preferably, the front panel has width and length dimensions that are the same as or greater than those of the front wall. In a possible embodiment of the invention, the centring element has an insert portion shaped and sized to pass tightly through the receiving opening. In this way, a compatible receivingopeningand insert portion are provided to ensure the centringof thefront panel. Here, the insert portion may be an extension or protrusion having a substantially cylindrical shape. Here, the receiving opening may be a cut-out portion correspondingto the insert portion and shaped and sized according to the insert portion. The receiving opening may have a substantially circular shape. In a possible embodiment of the invention, a socket portion is provided on a side of the centring element facing the front panel and is configured to accommodate an adhesive element for attaching the centring element to the front panel. In this way, a volume is created where the adhesive element will be positioned. Thus, the centring element directly contacts the panel rear face, ensuring that a reference is taken from the planar face of the front panel. That is, possible dimensional differences arising from the adhesive element are prevented. Here, the adhesive element may be any strip adhesive, for example, a double-sided tape, or a liquid-based adhesive, for example, silicone. Preferably, the adhesive element is silicone.

[0011] In a possible embodiment of the invention, receiving holes are configured on a bottom face of the socket portion facingthe front panel, which the adhesive element can at least partially fill. In this way, especially if the adhesive element is a liquid-based adhesive element, the excess amount fills the receiving holes, thereby preventing overflows of the adhesive element that could lead to possible dimensional differences. Here, to correctly position the centring element on the panel rear face, positioning aids such as a fixture or a template indicating the area where the centring element will be positioned may be used.

[0012] In a possible embodiment of the invention, the centring element has a body portion provided in a substantially hollow cylindricalform, and at least one body lug is configured on an outward-facing outer face of the body portion, configured to cause the clamping element to advance in an advance direction towards the frame inner face when the clamping element is rotated in the direction of rotation. Thus, the front panel is pulled and clamped, and the attachment of the front panel to the body frame is completed.

[0013] In a possible embodiment of the invention, the centring element has more than one body lug, and the body lugs are configured in the body portion so as to have a helix angle with a horizontal axis, and two respective adjacent body lugs define a lead in the advance direction of the clamping element. In this way, when the clamping element is rotated, it is guided by the rotational movement to advance in the advance direction. The plurality of body lugs mentioned herein are formed protrusion structures configured in sequence and defining a path that can guide the clamping element in the advance direction when the clamping element is rotated. The body lugs, positioned intermittently, are formed on the body portion to define a path substantially similar to a helix shape. The lead mentioned herein is a parameter that defines the distance the clamping element will travel in the advance direction.

[0014] In a possible embodiment of the invention, the clamping element comprises a clamping cavity that at least partially encloses the body portion, and at least one corresponding body lugshaped and sized accordingto the body lugs on an innerwallfacingthe clamping cavity. Thus, when the clamping element is rotated, it is guided by the rotational movement to advance in the advance direction. The corresponding body lugs mentioned herein are protrusion structures shaped and sized according to the body lugs. One or more corresponding body lugs may be configured on the inner wall. Preferably, there are two corresponding body lugs on the inner wall.

[0015] In a possible embodiment of the invention, the clamping element has a circumferential abutment face configured to bear against the frame inner face when the clamping element is attached to the centring element. Thus, the process of pulling and clamping the front panel, and the attachment of the front panel to the body frame, is completed.

[0016] In a possible embodiment of the invention, the clamping element comprises a step portion configured on the inner wall, on which the insert portion can rest when the clamping element is attached to the centring element. In this way, an inner volume is created in which at least a part of the insert portion can be seated when the clamping element is attached to the centring element.

[0017] In a possible embodiment of the invention, the front frame portion has a plurality of receiving openings provided spaced apart from each other in a width direction of the lower body, and a respective attachment system is provided in each receiving opening. In this way, the attachment of the longitudinally extending front panel is provided at certain intervals in the width direction. The centring and attachment of the front panel alongthe width direction are realized. Thus, the external positional aesthetic appearance of the front panel is guaranteed.

[0018] In a possible embodiment of the invention, the front frame portion comprises a central opening in a region between two respective receiving openings provided spaced apart from each other. Thus, on both opposite sides in the width direction of the central opening where electronic elements for touch buttons will be positioned, the attachment of the front panel to the front frame portion with dimensional and positional precision is ensured.

[0019] In a possible embodiment of the invention, the body frame has a rear frame portion extending in a direction substantially parallel to the front frame portion and configured to be identical to the front frame portion. In this way, a symmetrical body frame structure is provided, and during production, the front panel can be attached to either the rear frame portion or the front frame portion. The frame portion to which the front panel is attached is referred to as the front frame portion.

[0020] In a possible embodiment of the invention, the body frame is made of a metal material, and the front panel is made of a glass-ceramic material. Thus, the aligned attachment of the front panel made of glass-ceramic material to the body frame made of metal material is realized in a precise, easy, and simple manner.

[0021] Each possible embodiment disclosed in this description can be combined with other possible embodiments disclosed in this description, unless there are any technical restrictions.

[0043] DETAILED DESCRIPTION OF THE INVENTION

[0044] In this detailed description, the cooker hood (1 ) of the invention is described with examples that are intended only for a better understanding of the subject and do not have any limiting effect.

[0045] As can be seen in Figures 1 and 2, the exemplary cooker hood (1 ) is configured to draw in the air in a cooking area and direct it to a ventilation system (not shown in the figures). Said cooking area may be an area where cooking can be performed in a kitchen environment with devices such as a countertop hob, a built-in hob, or a freestanding oven. The cooker hood (1 ), in its most general form, consists of an upper body (2) and a lower body (3). The lower body (3) comprises a body frame (4) and, provided on the body frame (4), a front panel (5), a lighting assembly (6), and a filter assembly (7). The front panel (5) is configured to have at least one control element (40), particularly control knobs or control buttons, thereon and to allow for the control of the suction levels of the cooker hood (1 ). The front panel (5) may have a touch-sensitive panel structure. The front panel (5) is provided to extend longitudinally in the lower body (3). The front panel (5) extends in a width direction (x) of the cooker hood (1). The lighting assembly (6), on the other hand, has at least one lighting element (13) such as a lamp or an LED. There can be at least one lighting assembly (6) in the cooker hood (1 ). In Figure 1 , given for exemplary purposes, there is only one lighting assembly (6). This lighting assembly (6) can have one or more lighting elements (13). In the cooker hood (1 ) given as an example in Figure 1 , the lighting assembly (6) has two lighting elements (13). On the other hand, the filter assembly (7) comprises at least one filter. Said filters are configured to be able to purify the oil particles in the air suctioned from the cooking area. The filter assembly (7) in Figure 1 , given for exemplary purposes, comprises two filters. In the case where there is more than one lighting assembly (6) in the cooker hood (1 ), the filter assembly (7) can be provided between the opposing lighting assemblies (6). The upper body (2) is a part provided between the lower body (3) and the ventilation system and directs the air suctioned from the cooking area to the ventilation system. The upper body (2) is connected to the lower body (3) from a middle part of the lower body (3). The upper body (2) may be in the structure of a chimney similar to a hollow square prism form. The lower body (3) and the upper body (2) are in communication with each other in terms of airflow. That is, the air suctioned by the lower body (3) is directed to the ventilation system by the upper body (2). As can be seen in Figure 1 , the front panel (5), the lighting assembly (6), and the filter assembly (7) are provided to be supported by the body frame (4). The body frame (4) is configured to define a periphery of the lower body (3).

[0046] Referring to Figure 2, the body frame (4) comprises; a front frame portion (8), a rear frame portion (9) extending in a direction substantially parallel to the front frame portion (8) on the opposite side of the front frame portion (8), and side frame portions (10, 11 ) extending opposite each other between the front frame portion (8) and the rear frame portion (9). That is, there is a first side frame portion (10) and a second side frame portion (11) extending opposite each other. The frame portions (8, 9, 10, 11 ) are provided to define an inner space (12). The body frame (4) has a periphery substantially similarto a rectangular shape. The body frame (4), having a periphery substantially similar to a rectangular shape, is obtained to have four sides by being bent at the corner bend portions. The front frame portion (8) has a front wall (23) provided to be in a plane substantially parallel to the front panel (5). At least one receiving opening (16) is provided on the front wall (23). As can be seen in Figure 2, the front frame portion (8) has a plurality of receiving openings (16) provided spaced apart from each other in the width direction (x) of the lower body (3). The receiving openings (16) are obtained by cuttingthe respective regions of the front wall (23). In the exemplary body frame (4) in Figure 2, as also seen in Figures 8a and 8b, there are four receiving openings (16). The receiving openings (16) are formed to have a substantially circular shape. There is a central opening (42) in a region between two respective receiving openings (16) of the front frame portion (8) that are provided spaced apart from each other. The central opening (42) is formed to have a substantially rectangular shape. In the body frame (4), the front frame portion (8) and the rear frame portion (9) extending in a direction substantially parallel to the front frame portion (8) are configured to be identical to each other. Preferably, the body frame (4) is made of a metal material. As can be seen in Figure 3, the cooker hood (1 ) comprises at least one attachment system (19) that provides for the attachment of the front panel (5) to the body frame (4). A respective attachment system (19) is provided in each receiving opening (16) in the front frame portion (8) shown in Figure 2. There is an upper bent portion (24) configured on an upper edge of the front frame portion (8) extending longitudinally, and a lower bent portion (25) configured on a lower edge opposite the upper edge and extending longitudinally. Said bent portions (24, 25) are formed to have a bent form substantially similarto an L-shape.

[0047] As can be seen in Figure 4 and Figure 9, the front panel (5) has the form of a substantially planar plate. Preferably, the front panel (5) is made of a glass-ceramic material. The front panel (5) has an outward-facing panel front face (14) and a panel rear face (15) on the opposite side of the panel front face (14) and facing the body frame (4). The panel rear face (15) faces the frame outer face (17). The attachment system (19) comprises a centring element (20) connected to the panel rear face (15). The centring element (20) is provided to correspond to the respective receiving opening (16) on the front wall (23). That is, the respective centring element (20) and the respective receiving opening (16) are provided to have the same centre axis (E). To attach the centring element (20) to the panel rear face (15), there is an adhesive element (41 ) between the centring element (20) and the panel rear face (15). A template or a fixture may be used to correctly position the centring element (20) on the panel rear face (15). As can be seen in Figure 5, the centring element (20) is configured to pass at least partially through the body frame (4). Referring to Figures 6 and 7, the centring element (20) has an insert portion (22) shaped and sized to pass tightly through the receiving opening (16). Referring to Figures 3, 5, and 6, the front panel (5) is precisely aligned on the front frame portion (8) by the tight passage of the centring elements (20) through the respective receiving opening (16). The attachment system (19) further comprises; a clamping element (21 ) provided on a side opposite to the side where the front panel (5) is located, corresponding to the centring element (20). The clamping element (21 ) is configured to be attached to the centring element (20). The clamping element (21 ) is provided to have the same centre axis (E) as the centring element (20) and the respective receiving opening (16). When the clamping element (21) is rotated about the centre axis (E) in a direction of rotation (R), for example, clockwise, it is configured to be guided by the centring element (20) towards a frame inner face (18) facing the inner space (12). That is, when the clamping element (21 ) is rotated in the direction of rotation (R), it is configured to be guided by the centring element (20) to advance in an advance direction (M).

[0048] Figures 10a-1 Od are different views of the centring element (20) in the attachment system (19). The centring element (20) has a body portion (26) provided in a substantially hollow cylindrical form. The body portion (26), which is in a substantially hollow cylindrical form, defines a cavity (27). The insert portion (22), on the other hand, is provided to have a larger diameter than the body portion (26). A socket portion (28) is provided on a side of the centring element (20) facing the front panel (5). Said socket portion (28) is formed to define an inner cavity on the insert portion (22), which is closer to the front panel (5) than the body portion (26). The adhesive element (41) shown in Figure 4, particularly a liquidbased adhesive such as a silicone element, is filled into said socket portion (28). Said adhesive element (41 ) is an adhesive element that can show strong adhesion properties, especially to a glass-ceramic face. In this way, the centring element (20) is non- detachably attached to the front panel (5). In a state where the attachment of the centring element (20) to the front panel (5) is realized, an abutment face of the centring element (31) facing the panel rear face (15) directly bears against the panel rear face (15). Receiving holes (30, 32) are configured on a bottom face (29) of the socket portion (28) facing the front panel (5), which the adhesive element (41 ) can at least partially fill. In more detail, there is at least one first receiving hole (30) and at least one second receiving hole (32) on the bottom face (29). Preferably, multiple first receiving holes (30) and multiple second receiving holes (32) are formed on the bottom face (29). The first receiving holes (30) are located in a central region of the bottom face (29), away from the periphery. Said first receiving holes (30) may have a substantially circular shape. The first receiving holes (30) are provided to open from the bottom face (29) into the cavity (27). The second receiving holes (32) are located circumferentially in a region of the bottom face (29) close to the periphery. Said second receiving holes (32) may have a substantially rectangle-like shape. The second receiving holes (32) are provided to open from the bottom face (29) to the outside of the centring element (20). In this way, if the adhesive element (41) is used in an excessive amount, the excess amount can fill said receiving holes (30, 32). Thus, the adhesive element (41 ) is prevented from overflowing from the socket portion (28) and impairing the dimensional precision of the centring element (20). On the other hand, the centring element (20) also has at least one body lug (33) configured on an outward-facing outer face of the body portion (26), configured to cause the clamping element (21 ) to advance in the advance direction (M) towards the frame inner face (18) when rotated in the direction of rotation (R) as in Figure 5. Preferably, there are more than one, i.e., multiple, body lugs (33) on the body portion (26). The body lugs (33) are positioned with circumferential spacingfrom each other. Referring to Figure 10d, the body lugs (33) are positioned on the body portion (26) such that a follow path substantially similar to a helix-form is defined. That is, the body lugs (33) are provided on the body portion (26) so as to have a helix angle (h) with a horizontal axis (y). Furthermore, referring to Figure 10d and Figure 12, two respective adjacent body lugs (33) are configured to define a lead (a) in the advance direction (M) of the clamping element (21). On the body lugs (33), there are inclined faces to mate with the respective part of the clamping element (21 ). The centring element (20) is manufactured as a single piece from a plastic material, for example, a polyamide 6 (PA6) material.

[0049] Figures 11 a-11 d are different views of the clamping element (21 ) in the attachment system (19). The clamping element (21 ) has a body provided in a substantially hollow cylindrical form. The body, which is in a substantially hollow cylindrical form, defines a clamping cavity (36). The clamping cavity (36) is configured to at least partially enclose the body portion (26) of the centring element (20). On an inner wall (37) facing the clamping cavity (36), there is at least one corresponding body lug (35) shaped and sized according to the body lugs (33). Said corresponding body lug (35) is shaped and sized according to the follow path substantially similar to a helix-form defined by the body lugs (33). Said corresponding body lugs (35) are formed according to the helix angle (h) and lead (a) of the body lugs (33). The lead (a) is configured to cause the clamping element (21) to advance between 3 mm and 3.5 mm in the advance direction (M) when rotated in the direction of rotation (R). In this way, the process of pulling and clamping the front panel (5) can be easily applied to front panels (5) of different thicknesses. There are more than one corresponding body lugs (35) positioned spaced apart from each other on the inner wall (37). The exemplary clamping element (21 ) in Figures 11 a-11 d comprises two corresponding body lugs. Each corresponding body lug (35) has a form substantially similar to a C-shape. On the other hand, the clamping element (21 ) has at least one gripping wall (34). As can be seen in Figures 11 a and 11 b, the clamping element (21) has at least one pair of gripping walls (34) provided opposite each other. Thanks to the gripping walls (34), the clamping element (21 ) can be easily rotated in the direction of rotation (R) with the help of an external tool, for example, a hand torque wrench. Referring to Figures 11 c, 11 d, and 12, the side of the clamping element (21 ) facing the centring element (20) is formed to have a larger diameter. In more detail, the clamping element (21) has a circumferential abutment face (38) configured to bear against the frame inner face (18) when the clamping element (21 ) is attached to the centring element (20). Furthermore, referring to Figures 13 and 14, the clamping element (21) comprises a step portion (39) configured on the inner wall (37), on which the insert portion (22) can rest when the clamping element (21 ) is attached to the centring element (20). The clamping element (21) is manufactured as a single piece from a plastic material, for example, a polyamide 6 (PA6) material.

[0050] The attachment of the front panel (5) to the front frame portion (8) with the attachment system (19) of the invention in an easy, simple, and low-cost manner and with precision is as follows: First, the centring element (20) is attached to the panel rear face (15) by being adhered with an adhesive element (41 ). Similarly, a plurality of centring elements (20) are attached to the front panel (5) in the width direction (x) of the front panel (5). When the front panel (5) having the centring elements (20) is pushed towards the front wall (23) of the front frame portion (8), each centring element (20) corresponds to the respective receiving openings (16) on the front wall (23). In this case, the insert portions (22) of the centring elements (20) pass tightly into the respective receiving openings (16), and at least a part of the front panel (5) rests on the front wall (23). In this way, the front panel (5) is aligned on the front frame portion (8) easily and precisely. Thanks to this alignment, the opposing portions of the front panel (5) on the top-bottom and left-right sides, which have larger dimensions than the front wall (23), are provided to be almost equal to each other, thereby improving the external aesthetic appearance of the front panel (5). Then, the clamping element (21) is rotated on the body portion (26) of the centring element (20) remaining in the inner space (12), about the centre axis (E) in the direction of rotation (R). An external tool such as a hand torque wrench can be used for this rotation operation. With the rotation operation applied in the direction of rotation (R), the corresponding body lugs (35) on the clamping element (21 ) are guided by the body lugs (33) on the centring element (20), causing the clamping element (21 ) to advance in the advance direction (M). Furthermore, as can be seen in Figures 13 and 14, the corresponding body lugs (35) are wedged in the follow path similar to a helix-form defined by the body lugs (33). When the clamping element (21 ) is attached to the centring element (20), the abutment face (38) bears against the frame inner face (18). This aforementioned operation is applied in the same way to all attachment systems (19) on the lower body (3). Thanks to the advance of the clamping elements (21 ) in the advance direction (M) and the wedging of the corresponding body lugs (35), the front panel (5), having the non-detachably attached centring elements (20) thereon, is clamped by being pulled towards the front wall (23).
