STATE OF THE ART 10 In the field of cooking appliances, especially kitchen equipment with a cooktop or cooking surface. Design and production play a significant role. These devices use gas or electricity as a heat source. or you can use different solutions such as induction. In general, a top plate is the cooking surface of the appliance. It includes the surface and the burners (cooking zones) that can be positioned on it. This top 15 The turntable is the visible part of the device and the area where user interaction is most intense. The top sheet allows users to cook and access the control elements comfortably. The design is made taking ergonomics and durability into consideration. In a cooking appliance, the base and four or more side walls are usually 20 cm apart from the top plate. a housing that supports and delimits an internal chamber where the internal components will be placed It includes side walls that connect the top panel to the base, thus contributing to the device's structural integrity. It ensures its integrity. The material thickness of the side walls and the bottom wall prevents bending and Shaping through deep drawing processes is important in terms of durability. Furthermore, Additional elements such as control surfaces, buttons, or electronic components are specific within the design. They can be positioned in various areas. Consequently, both the choice of materials and the production method, Critical factors such as the durability of the cooking appliance, heat distribution, and ease of installation are directly affected. It has an effect. Typically, the housing is made of a metal sheet. The edges of the metal sheet... raised upwards, a glass or glass ceramic top plate, to the upper edge of the lateral walls is being placed. 30 WO2023140798, a thin and flat enclosure with a raised lateral wall. a base support plate; a transverse bridge extension rising on the base support plate and attached directly to the housing from the inside at opposite ends of the bridge extension 35 It describes a furnace. 2 A BRIEF DESCRIPTION OF THE INVENTION The aim of the invention is to create a structure that can maintain its structural integrity without requiring an additional reinforcing element. The goal is to create a stove with a casing made of flat metal sheet. To achieve the aforementioned purpose, the invention consists of a base and a structure rising vertically from its outer periphery. A tray-shaped sheet metal enclosure with perimeter walls; an inner section underneath the top edge of the enclosure. It relates to a hearth containing a top plate that is positioned in a way that limits the room. The hearth is the first lateral The wall and the second lateral wall, which is perpendicular to and adjacent to it, are positioned diagonally to each other on the same axis. The first and second winglets are arranged in such a way that they are opposite each other in sequence, and each wing has 10 It contains a corresponding lateral indentation upon which it rests. Each fin, on the opposite edge a joint that fits into the lateral recess, ensuring the enclosure retains its shape. It is formed. Preferably, this structure is located at the corner where each perimeter wall of the enclosure meets. This has been implemented. In this way, the fins and lateral walls are at least close to each other at the corners. Partial passage is ensured and the gaps formed at the edge joints are reduced. 15 Preferably, the flange allowance from the adjacent side recess of the first and / or second fin, It is adjusted to match the sheet metal thickness. In this way, there is no protrusion at the corners of the enclosure. A tray form can be obtained without it. Also, the fin, the thickness of the corresponding edge Because it rests against the forehead, the pressure caused by any external force will be 20 The tension is reduced, and the fin maintains its original shape without bending during deflection. Ideally, the combined height of the first and second ailerons should correspond to the height of the first or second aileron. It is equal to the height of the second lateral wall. In this way, the cross fins form the lateral edge shape. It holds the casing form together while providing maximum strength without compromising its shape. 25 Ideally, the perpendicular and adjacent corners of the first and second fins are rounded. Rounded corners reduce the contact area and prevent the tray from flexing in any way. This prevents the fins from deforming by applying force to each other. Ideally, the outer extensions of the ailerons should be positioned downwards with the first aileron pointing downwards and upwards with the second aileron pointing upwards. They have an elbow-like form that extends outwards, facing each other perpendicularly. In this way, they are diagonal and A high-strength interlocking structure has been achieved. Preferably, sheet metal 35 along the corresponding lateral recess along the inner wall of the first and second fins. It is adjusted to rest completely flat against the wall by pre-tensioning along its thickness. In this way, the tray adjacent lateral walls supporting each other and locking under prestressing 3 This has been ensured. In this case, in the event of any flexing in the metal sheet housing, lateral... The walls are able to maintain their predetermined vertical positions. Preferably, the first and second lateral walls should be enclosed in a fixed metal sheet housing to provide prestressing. Corner 5 along the corresponding perpendicular bending lines that delimit the base It forms a curve that is either perpendicular or partially obtuse. In this way, the lateral walls It can be obtained simply by bending sheet metal, for example through a molding operation, and The structural strength of the enclosure is high. Preferably, 10 formed along the edge of the first lateral wall and the edge of the second lateral wall facing each other. The connection line is in a zigzag form. The zigzag form is due to the fact that the connections to the housing are coming from different directions. Despite the forces applied, it ensures the structural integrity of the enclosure is maintained. Ideally, the first lateral wall and the upper edge of the second lateral wall should support the top slab. Their heights are adjusted to be equal on the plane. In this way, for example, a flat glass top plate has 15 The stove can be installed by placing it on the side walls. Ideally, the first and second ailerons should be positioned laterally facing each other. The edges are adjusted to form the bottom half and the top half. In this way, a simple cut is made. With this operation, winglets can be obtained and the stretches that may occur after bending are 20 In this way, the vertical position of the lateral walls is maintained. BRIEF DESCRIPTION OF THE FIGURES Figure 1 is a top-down perspective view of a representative structure of the furnace that is the subject of the invention. 25 Figure 2 is a perspective view of the lateral walls of the furnace sheet metal casing before bending. Figure 3 is a close-up view of the corner section of the sheet metal enclosure. DETAILED DESCRIPTION OF THE INVENTION In this detailed description, the subject matter of the invention may be developed without any restrictions and The explanation is given with references to examples simply to better illustrate the topic. 35 Figure 1 shows a built-in cooktop from a top perspective. It has a flat glass ceramic top. (1) each of which defines the cooking zones and has a heating element (not shown) 4 There are heated areas. The top plate (1) is made of one-piece metal sheet in the form of a tray. A manufactured enclosure (10) is mounted on its upper edges. The enclosure (10) is perpendicular to each other. and in strip structure there is a first lateral wall (12) and a second lateral wall (14). Here, the first lateral wall (12) is on one side of the hearth and the second lateral wall (12) is in front of the hearth. It corresponds to the part. In the extended representation in the right hand direction, the first lateral wall (12) 5 and the adjacent and contiguous corner of the second lateral wall (14) is shown. In the middle of the corner It includes a junction line (2) with a zigzag structure. In Figure 2, the metal sheet housing (10) is flat and level, not yet in tray form. The surrounding walls are shown in perspective, unbent. Flat and smooth metal. Wings were obtained by cutting each corner of the sheet metal in mirror symmetry. Each wing was bent perpendicularly 10 first lateral wall (12), second lateral wall (14), third lateral wall (16) and fourth lateral wall Perimeter walls are obtained, formed by the wall (18). In the perimeter walls, the first lateral wall (12) and third lateral wall (16) together with the second lateral wall (14) and fourth The lateral wall (18) is again in the form of a pair of equal size and shape. The first lateral It has a T-like form due to the cut at the corners of the wall (12) and the third lateral wall (16). 15 On the other hand, the second lateral wall (14) and the fourth lateral wall (18) form an inverted T-like shape. It is in structure. Here, for the sake of example, only the first lateral wall (12) and the second lateral wall wall (14) is described. However, as mentioned above, other lateral walls (16, 18) These have a similar structure, and to avoid repetition, the details are presented here. It has not been mentioned. 20 A side at the top of the lateral edge facing the first lateral wall (12) and the second lateral wall (14). It is cut in such a way as to obtain an indentation (124) and a first fin (126) in the lower half. In this way, The half above the first fin (126) forms the lateral recess (124). The lateral recess (124) reaches the straight upper edge (122) of the first lateral wall (12) at a right angle. First A short slit was made inwards from the corner to form the lower edge of the fin (126). 25 The edge of the second lateral wall (14) adjacent to this one forms a second winglet (146) in the upper half. It is cut in such a way as to make the half under the second flap (146) into a side recess. (144) is formed. The upper part of the lateral recess (124) of the second lateral wall (12) is vertical. It reaches the flat top edge (142). Flange allowance of the first and second fins (126, 146) (L) is equal to the sheet metal thickness (h) of the enclosure (10). The upper edge of the first lateral wall (12) is (122) and 30 a bend line (121) at the base (11) boundary which is parallel and at a distance equal to the edge height The first lateral wall (12) bends upwards perpendicular to the base (11) along the length. This The process is carried out on the second lateral wall (14) which is again bordered by the base (11) and parallel to the upper edge (142) and It is applied as a perpendicular bend along a distanced bend line (141). All circumferential The edges (12, 14, 16, 18) are perpendicular to the base (11) and bent upwards. Bending with 35 in the enclosure (10) the perpendicular sides formed by the facing lateral sides form the junction line (2) It is forming. In Figure 3, when the tray form of the enclosure (10) is provided, the perimeter walls (12, 14, 16, 18) The first lateral wall, representing one of the corners formed by the sides facing each other. (12) and the corner of the second lateral wall (14) facing each other are shown. All of the enclosure (10) The corners have a similar shape. The first lateral wall (12) and the second lateral wall (14) are opposite each other. The upper edges (122, 124) are aligned in the same plane. 5 to the upper edge (122) of the first lateral wall (12). lateral indentation (124) on the vertical edge along the face of the second lateral wall (14) second It rests on the surface of its winglet (146) that faces it. The first lateral wing is diagonally opposite to it. the side of the first wing (126) extending in the lower half of the wall (12) the side of the second lateral wall (14) The part facing the recess (144) is also completely facing the side recess (144) from the inside. It rests on. Here, the flange allowances (L) of the first and second winglets (126, 146) are 10 to the sheet metal thickness. Since (h) is adjusted equally, the corresponding side recess (144, where each of the fins (126, 146) is placed 124) does not make an extension outwards from its width. That is, the first lateral wall (12) The front part (125) of its wing (126) is in the same plane as the outer surface of the second lateral wall (14). Similarly, the front part (145) of the second wing (146) of the second lateral wall (14) is the first lateral It is in the same plane as the outer surface of the wall (12). Thus, it is extremely dimensionally stable and 15 A lock resistant to bending is obtained. First lateral wall (12) and second lateral the junction line (2) formed along the facing side edges of the wall (14) first wing (126) and perpendicular on two axes along the corner on the faces of the second wing (126) facing each other. It forms a progressive zigzag shape. On the other hand, both the side of the first wing (126) the outer corner of the part facing the recess (124) and the second wing set adjacent to it 20 (146) the outer corner of the part facing its side recess (144) is given a radius It is rounded. Thus, the first and second flaps (126, 146) meet each other in the flexing state. The contact surfaces are made linear, and the gap between them is minimized during flexing. It has been downloaded.
