Description

[0001] The invention relates to a cooktop with a decorative frame and a seal attached to the underside of the decorative frame. Furthermore, the invention relates to a device with such a cooktop and a worktop having a recess in which the cooktop is arranged.

[0002] A corresponding cooktop is known from DE 10 2007 012 481 A1. This patent provides for a circumferential, closed seal on the underside of an outwardly projecting rib of the decorative frame, which is also arranged on the upper side of the worktop. Such a seal seals the gap between the decorative frame and the worktop, preventing contaminants from getting under the decorative frame and potentially into the recess in which the cooktop is recessed.

[0003] In conventional designs, the seal is formed as a single, continuous strand. However, a problem arises at the opposing ends of this strand, as they are positioned vertically one above the other to achieve the closed ring of the seal. This results in a thickening of the seal in the vertical direction. This is undesirable, firstly with regard to the horizontal positioning of the decorative frame, and secondly, it can lead to unsealed gaps at the resulting sloping, non-double-layered sections of the seal.

[0004] US Patent 6,043,462 A describes a bracket for a cooktop for installation in a cutout in a countertop. The bracket comprises a frame unit that has a support section on which the cooktop is held.

[0005] DE 42 02 807 C1 describes an arrangement for attaching a stainable panel to an adjacent worktop of a kitchen furniture, with a retaining frame for receiving the panel edge and with sealing agents that seal the panel edge against the retaining frame.

[0006] The object of the present invention is to provide a cooktop and a device with such a cooktop in which a seal attached to the underside of the decorative frame enables a reliable seal all around.

[0007] This task is solved by a cooking surface and a device according to the independent claims.

[0008] A cooktop according to the invention comprises a cooktop plate, a decorative frame surrounding the cooktop plate, and a seal attached to the underside of the decorative frame. The seal is designed as a continuous, closed strand with strand ends that overlap in a plane parallel to the underside of the decorative frame. This design prevents the formation of seal thickenings at the adjacent strand ends in the vertical direction. In the design according to the invention, the strand ends are thus arranged or positioned side by side in certain areas when viewed horizontally.This design allows for a particularly noteworthy, completely closed seal on the underside of the decorative frame, without creating any undesirable thickening of the seal in the vertical direction. Furthermore, height differences in the area of ​​the pipe ends are eliminated, thus preventing any unwanted unsealed gaps.

[0009] It is particularly advantageous that the pipe ends are arranged overlapping over a length greater than or equal to 1 cm, especially between 1 cm and 5 cm. This ensures a reliable seal, particularly in the area of ​​the pipe ends.

[0010] In the cooktop according to the invention, the strand ends are arranged to be in direct contact with one another, at least in certain areas along the overlapping path length. Undesirable labyrinthine configurations, which would nevertheless result in unsealed gaps, can thus be avoided.

[0011] Preferably, the strand ends are arranged parallel to each other. This makes it particularly advantageous to achieve a reliable and durable seal in the area of ​​the ends.

[0012] Preferably, the pipe ends are designed to have the same height, at least in some areas along the overlapping length, when viewed vertically. This avoids undesirable vertical protrusions and thus prevents unsealed gaps.

[0013] The seal can be, for example, a silicone seal or a foam bead.

[0014] Furthermore, the invention relates to a device with a cooktop according to the invention and an advantageous embodiment thereof, and a worktop having a recess in which the cooktop is arranged. The seal, which is arranged on the underside of the decorative frame, is formed between the decorative frame and a top surface of the worktop.

[0015] An embodiment of the invention is explained in more detail below with reference to schematic drawings. These show: Fig. 1 a schematic partial sectional view of an embodiment of a device according to the invention; and Fig. 2 A view from below of the decorative frame with the seal in the area of ​​the strand ends.

[0016] In the figures, identical or functionally equivalent elements are given the same reference symbols.

[0017] In Fig. Figure 1 shows a partial sectional view of an embodiment of a device 1 according to the invention. The device 1 comprises a cooktop 2, which has a cooktop surface 3 that can be made, for example, of glass or glass-ceramic. Cooking vessels containing food can be placed on the cooktop surface 3 for the purpose of preparing this food.

[0018] The hob 2 also includes a decorative frame 4 surrounding the hob plate 3 on all sides, which can be made of stainless steel, for example.

[0019] Furthermore, the cooktop 2 includes a mounting frame 5, separate from the decorative frame 4, which may, for example, be made of sheet steel. The mounting frame 5 is connected, in particular, to decorative frame sections 4a of the decorative frame 4 in mounting frame sections 5a.

[0020] As can be seen from the presentation in Fig. As can be seen in Figure 1, the cooktop 2 is recessed into a recess 6 in a worktop 7. The decorative frame 4 includes a substantially horizontally projecting rib 4b, which also extends laterally and overlaps a top surface 7a of the worktop 7.

[0021] A seal 8 is formed on the underside 4c of this web 4b, and is also formed to rest on the upper side 7a. The seal 8 is formed completely around the underside 4c, so that a continuous, closed boundary is formed.

[0022] In Fig. Figure 2 shows a view from below of the decorative frame 4, focusing in particular on the underside 4c. It can be seen that the seal 8 is essentially formed in a horizontal plane, namely the xz-plane. In particular, the seal 8 is formed entirely in a plane oriented parallel to the underside 4c.

[0023] As shown in the presentation according to Fig. As shown in Figure 2, the seal 8 is essentially a single strand along its entire length and exhibits a partial overlap in the region of strand end pieces 8a and 8b. This overlap is not in the vertical direction (y-direction), but exclusively in the horizontal x-direction (xz-plane). In particular, the seal 8 has a substantially uniform vertical height along its entire circumferential length and is therefore essentially uniform in height in the y-direction.

[0024] As shown in the illustration according to Fig. As can be seen in Figure 2, the path length 9, over which the strand end pieces 8a and 8b are arranged next to each other in this horizontal direction, is preferably between 1 cm and 5 cm.

[0025] Furthermore, in Fig.As can be seen in Figure 2, the strand ends 8a and 8b run parallel and directly against each other over the entire overlapping path, or path length 9, so that they are also in contact. This results in a particularly strong seal in the x, z, and y directions in the areas of these end pieces.

[0026] Furthermore, it can be seen that the strand end 8b is guided past the strand end 8a, which transitions straight to the further strand, by a strand section 10 that is curved in a particularly S-shape. This S-shaped strand section 10 is thus free of corners, so that even when creating this shape of the seal 8 in the area of ​​the strand ends 8a and 8b, no undesirable seal protrusions due to complex shapes of the seal 8 are formed. Moreover, a front face 81a of the strand end 8a is also positioned at a certain distance from the curved strand section 10, so that no undesirable contact and thus potentially no undesirable seal protrusion in the y-direction is formed.
