Description

[0001] A HOB WITH A BASE SUPPORT SHEET REINFORCEMENT ELEMENT

[0002] TECHNICAL FIELD

[0003] The invention relates to a hob with a control panel and a metal base sheet on which heating plates are placed.

[0004] STATE OF THE ART

[0005] A hob with a control panel has a base sheet that defines a cavity with elevated peripheral side edges and a top plate that covers it from above. Depending on the type of hob, electrical switches or gas taps are mounted on the base sheet and are controlled by adjustment knobs extending from the top plate, accessible from the control panel. The base sheet is usually obtained by plastic forming in a mold that allows the side edges of a thin and flat metal sheet plate to be elevated to form a cavity. The top plate is also formed by making holes in a flat and level sheet and is fixed over the base sheet via an edge flange to delimit a chamber. Since the base sheet is thin, it is reinforced against deformation due to bending by placing a strip under the base part or by forming the base.

[0006] WO2023140798A1 relates to a hob with a support element. It involves a thin and flat base support sheet with an elevated lateral wall that defines a housing; a bridge extension that extends transversely rising above the base support sheet; and a rigid reinforcement element in the form of a bridge having a first and second leg at opposite ends of the bridge extension, respectively, provided to be directly attached to the housing from its inner part.

[0007] BRIEF DESCRIPTION OF THE INVENTION

[0008] The object of the invention is to prevent deformation in the base sheet in cooking devices that have a thin and flat metal base sheet.

[0009] In order to achieve the above objective, the invention relates to a hob including a thin and flat base support sheet with an elevated lateral wall defining a housing, a bridge extension extending transversely rising above the base support sheet, and a rigid reinforcement element in the form of a bridge having a first and second leg at opposite ends of the bridge extension, respectively, provided to be directly attached to the housing from the corresponding contact part. The reinforcement element includes a wing provided at a lower end of each of the first and second legs, which directly sits on the base support sheet and extends transversely relative to the base support sheet. The rigid reinforcement element forms a counter-resistance via the first and second legs against possible bending due to heating during cooking of the hob or stresses created by functional elements attached to the housing in the thin and flat base support sheet. In this way, the strength of the hob is increased. Preferably, the hob takes the form of a basin forming a housing by molding or bending a single-piece sheet. In this case, the lateral edges rise completely surrounding the housing. Additionally, with the use of wings, problems that may occur due to shaking or toppling of the reinforcement element inside the hob are prevented.

[0010] In a preferred embodiment of the invention, the wings are arranged to contact the upper wall of the base support sheet along one edge. Thus, the fixation is strengthened by applying a resistance force against the toppling of the reinforcement element.

[0011] In a preferred embodiment of the invention, the reinforcement element is in the form of an inverted U-like integral metal strip including a bridge extension extended between the upper ends of the opposite first and second legs. Thus, it becomes possible for elements such as gas distribution pipes or electrical connection cables, for example, to pass under the bridge structure of the reinforcement element located over the cavity, and the reinforcement element can be easily adapted to hob designs with different variants.

[0012] In a preferred embodiment of the invention, an elongated opening is provided on the bridge extension. Thus, the center of gravity of the reinforcement element is balanced, and the weight of the part is reduced.

[0013] In a preferred embodiment of the invention, the reinforcement element is aligned near and parallel to a long lateral wall of the base support sheet. In this way, the reinforcement element increases the structural strength by being fixed near the end parts of the long side where the thin and flat base support sheet may deflect the most.

[0014] In a preferred embodiment of the invention, the first and second legs extend outward in opposite directions and have an L-like form that rests flat against the housing from the lower end. In this case, the position of the legs can be easily seen during the placement of the reinforcement element into the housing and can be aligned accordingly. In a preferred embodiment of the invention, an opening and a corresponding counter opening respectively formed on the cavity aligned with the first and second legs, and has a tab extending through the openings on the first or second leg. In this case, when the first and second legs sit on the housing, the tab passes through the corresponding opening, ensuring the fixation of the reinforcement element with the first or second leg.

[0015] In a preferred embodiment of the invention, the tab passes through the counter opening corresponding to the second leg, which extends perpendicularly, and is adjusted to rest along an inner edge extending toward the first leg on the base support sheet. In this way, a compact structure is obtained by strengthening the assembly of the reinforcement element.

[0016] In a preferred embodiment of the invention, the tab extends perpendicularly from the first or second leg and has an L-like form. Thus, a compact structure is obtained by strengthening the assembly of the reinforcement element. Also, by providing the assembly with the use of a tab without using an additional connection element, a cost advantage is created.

[0017] In a preferred embodiment of the invention, a gap is formed on the first or second leg on which the tab extends perpendicularly, providing flexibility. Thus, the necessary flexibility is provided for the process of passing the tab through the opening during the assembly process.

[0018] In a preferred embodiment of the invention, a neck portion provided to allow the first and second legs to extend in a bendable form at the lower end. In this way, after the tab passes through the opening, it becomes possible to fix the reinforcement element to the housing without the need to bend it from the lower part of the housing.

[0019] In a preferred embodiment of the invention, the height of the neck portion is essentially equal to the thickness of the base support sheet. Thus, when the tab passes through the opening, it becomes possible to fix it by rotating it adjacent to the lower end of the base support sheet.

[0020] In a preferred embodiment of the invention, the upper surface of the neck portion is aligned on the same axis as the wings. Thus, the assembly of the reinforcement element to the base support sheet is strengthened.

[0021] In a preferred embodiment of the invention, a depression is extending along the front part of the housing parallel to the bridge extension, and the first and second legs are adjusted close to the opposite ends of the corresponding depression. The depression increases the structural strength of the thin and flat base support sheet against stresses. On the other hand, the resistance of the depression against movement in the bending direction is increased together with the reinforcement element extending transversely.

[0027] DETAILED DESCRIPTION OF THE INVENTION

[0028] In this detailed description, the development subject to the invention is explained with references to examples in a way that will not constitute any limitation and only to better explain the subject.

[0029] In Figure 1 , a gas hob is shown from above with the top plate removed. The hob has a base support sheet (10) obtained by molding a flat and thin steel sheet. The base support sheet (10) has a rectangular-like form obtained by cutting from a roll. The base support sheet (10) is shaped in a drawing mold so that its edges elevate to form a lateral wall (12) along its length. Thus, a housing (14) is defined with the lateral wall (12). The lateral wall (12) is bent outward from its upper end to provide a flange. A burner (1 ) is mounted into the housing (14) with the help of supporting elements (not shown). The burner (1) is connected to provide fluid communication via a gas distribution pipe (2). The gas distribution pipe (2) is connected from one end to a corresponding gas tap (3) to control the flow rate. The gas taps (3) are connected to each burner (1) via the gas distribution pipe (2) between them. The gas taps (3) are arranged sequentially and spaced apart on a front part of the housing (14). The gas taps (3) are aligned on an indentation (18) that extends transversely along the front part of the housing (14). A reinforcement element (20) obtained by bending a thin and flat metal strip is mounted on the upper surface of the housing (14) extending in the form of a bridge passing under the gas distribution pipe (2) extending from the gas taps (3).

[0030] In Figure 2, the reinforcement element placed transversely into the base support sheet is shown in perspective. The reinforcement element (20) is in the form of an inverted U. The reinforcement element (20) has a straight and long bridge extension (21 ) extending downwardly from its opposite ends to form a first leg (24) and a second leg (28), respectively. The first and second legs (24, 28) are of equal form and are arranged in mirror symmetry to each other. A wing (22) extending transversely relative to the base support sheet (10), which directly sits on the base support sheet, is located at a lower end (242) of the first leg (24) and a lower end (282) of the second leg (28). The wing (22) forms an L-like shape with the first leg (24). The wings (22) are manufactured by cutting from a metal sheet. The wings (22) rest along one edge (222) on the upper wall (11 ) of the base support sheet (10), as shown in Figure 1 , thereby preventing problems that may occur due to shaking or toppling. An elongated opening (23) is provided on the bridge extension (21) balanced to the center of gravity. The opening (23) extends in an elliptical form. The bridge extension (21 ) includes a side wall (26) obtained by bending down the two long edges of a strip. The side wall (26) follows the first and second legs (24, 28) to take a U-like form. The lower end of the side wall (26) is thinned on the first leg (24) and the second leg (28) to form neck portions (27). The front surface of the neck portion (27) is aligned on the same axis as the wing (22). The height of the neck portion (27) is equal to the thickness of the base support sheet (10) and also equal to the distance between the wings (22) and the base support sheet (10). A tab (25) is located adjacent to the neck portion (27) formed on the second leg (28) and fixed on the base support sheet (10). The tab (25) extends perpendicular to the base support sheet (10) and has an L-like form. A gap (29) formed to provide flexibility is located on the second leg (28) formed with the neck portion (27).

[0031] In Figure 3, the assembly state of the base support sheet and the reinforcement element shown in Figure 1 is shown from below. A corresponding opening (16) corresponding to the first leg and a counter opening (17) corresponding to the second leg, aligned with the first and second legs (24, 28), are provided on the housing (14) adjacent to the channel-like depression (18). The opening (16) and the counter opening (17) are of equal structure and extend transversely in a short cut formed by cutting the housing (14). The reinforcement element (20) is placed on the upper wall of the housing (14) such that the tab (25) on the second leg (28) passes through the counter opening (17). When the reinforcement element (20) sits on the upper wall of the housing (14), the neck portions (27) are aligned with the thickness of the openings (16, 17). Thus, with the connection of the tab (25), the reinforcement element is fixed without using an additional connection element. In this way, it is prevented that the reinforcement element (20) is pulled out by being pulled over the housing (14). Also, with the use of a flexible tab, ease of assembly is provided and a compact hob structure is obtained. In Figure 4, the assembly state of the reinforcement element mounted on the base support sheet is shown from the side. The tab (25) provided on the second leg (28) passes through the counter opening (17) on the housing (14) and extends vertically under the base support sheet (10). The base support sheet (10) is fixed on the neck portions (27) provided on the first and second legs (24, 28). After the base support sheet (10) is fixed from the tab (25) and neck portions (27), the edges (222) of the wings (22) extend directly on the base support sheet (10).

[0032] Since the gas distribution pipes (2) pass under the reinforcement element (20) due to the height of the bridge extension (21 ), it is possible to fix the rigid reinforcement element (20) over appropriate parts through openings (16) and counter openings (17) without changing the positions of the functional elements of the hob. In this case, the stresses applied during the connections of the elements located on the base support sheet (10) or during transport are countered via the first leg (24) and second leg (28) connections and the bridge extension (21) that keeps the distance between them, eliminating any possibility of deformation.
