Definitions

  • the invention relates to a hob and a method for installing such a hob or for assembling such a hob.
  • the hob has a hob plate and heating devices underneath, the heating devices being arranged and fastened on a flat carrier plate, in particular being carried by the carrier plate.
  • a corresponding hob is from the EP 1335632 A2 known.
  • the heating devices in the form of induction heating coils are attached to different holes which are arranged in specific hole patterns, for example by screwing them tight.
  • longitudinal slots can be provided. The different holes or longitudinal slits allow the heating devices to be positioned in a variable but precisely definable manner.
  • the invention is based on the object of creating a hob as mentioned at the outset and a method for assembling such a hob, with which problems of the prior art can be solved and in particular it is possible to fasten heating devices advantageously on the support plate.
  • the cooktop has a cooktop plate and heaters under the cooktop plate. Furthermore, it has a flat support plate for the heating devices, which is flat, runs parallel to the hob plate and has an upper side.
  • the support plate carries the heating devices on the upper side, these being held in place. This means that they cannot move when the hob is transported, and their position always remains the same.
  • holding means are provided for each heating device hold flat with an accuracy against movement such that they can advantageously move a maximum of 1 cm.
  • each heating device has at least one laterally protruding retaining tab, advantageously two retaining tabs.
  • Each holding lug has latching means, the holding means having counter-latching means in order to form or enter into a latching connection with the latching means of the holding lug.
  • Such a snap-in connection can advantageously be designed in such a way that it forms at least one protection against loss, so that after the snap-in connection has been established, the retaining means cannot be lost from the retaining tab or from the heating device or, for example, cannot fall off.
  • a heating device with latched holding means can be transported separately in order to then be connected to the carrier plate.
  • the snap-in connection play can be provided in the direction perpendicular to the carrier plate, the snap-in connection does not necessarily have to have a single possible position.
  • the holding means are fastened to the upper side of the carrier plate, specifically detachably fastened, such a detachment of the fastening being possible in the direction perpendicular to the carrier plate. Attachment by gluing is advantageously improved, but can be pulled off or released with appropriate force. In a direction parallel to the surface of the support plate, the holding means are fastened to the support plate with a form fit, since this is actually the only possibility of movement for the holding means or the heating device in a fully assembled hob.
  • the holding tab runs over the carrier plate or is located over the carrier plate, it rests on the holding means or is connected to the holding means in a latched manner.
  • the connection is advantageously form-fitting and can be formed at least partially by the snap-in connection or the elements provided for this purpose. Additional elements can be provided for a positive and therefore stable connection.
  • each heating device can have exactly two holding tabs, which are preferably distributed evenly. Particularly preferably, they are opposite one another on the heating device.
  • a retaining tab or each retaining tab is from an outer Border of the heater to the outside, so that it is easily accessible when assembling the hob, both with it latched holding means and without.
  • the latching means on the retaining tabs can be in the form of latching openings. They have at least one locking edge, preferably a locking opening has two spaced locking edges. These are advantageously parallel to each other. A latching hook of the holding means can act on each latching edge. Each holding tab preferably has exactly one latching opening.
  • All retaining tabs are advantageously of identical design, which can also apply to the retaining means. This makes it possible to simplify the manufacture and the provision of the parts for assembling the cooktop.
  • the retaining tab is flat. It can run parallel to the surface of the carrier plate. It can be designed in a simple manner and does not require any additional or complex overall height.
  • the retaining tab can be provided on a carrier or heating element carrier of the heating device. In this case, it can either be formed in one piece on this heating element carrier, in particular if this is a plastic injection-molded part. Such a heating element carrier can be plate-shaped. Alternatively, the retaining tab can be connected to such a heating element carrier with a type of connecting section or connecting part, so that it is not attached to it in one piece, but can be attached or attached. Then, as explained above, it can also be provided that all the retaining tabs together with the connecting parts are of identical design, that is to say they are only available in a single type, and are then connected to the heating element carriers in the same way.
  • a heating element carrier mentioned is advantageously also made of plastic, as is known per se.
  • each holding means advantageously has two latching hooks.
  • Such a latching hook can have a latching bevel at the top at a free end and a latching action downwards. This can be formed by a latching projection pointing towards the carrier plate, which projection is formed near or at the free end of the latching hook.
  • a height of the latching projection above the carrier plate and/or above the retaining tab can be at least twice to three times the thickness of the retaining tab.
  • the holding means can be attached to the holding tab by the latching connection or snapped on, but there is still room for movement even after snapping in, which allows the holding means to be moved relative to the retaining tab and thus relative to the heating device, for example for easier assembly on the carrier plate. Due to the mobility within this latching connection, a spring deflection with a spring height of the heating device above the carrier plate can preferably also be achieved.
  • Two latching hooks are advantageously provided on a holding means as counter-latching means. These two latching hooks can be of the same design and protrude from the holding means at a distance from one another.
  • the two latching hooks can, so to speak, be arranged back-to-back or arranged on a base part in such a way that the said latching projections point in opposite directions or away from one another. They can be designed and arranged in mirror symmetry, such a plane of symmetry running in the middle between them.
  • a centering projection can be formed on the holding means, which protrudes in a direction at right angles to the surface of the carrier plate.
  • This centering projection can be used to find the correct position in relation to one another when the holding means are attached to the holding tab, in particular for simple and correct production of the latching connection.
  • the centering projection can extend through an opening in the holding tab, in particular an opening that is completely bordered.
  • this can be the same snap-in opening that forms the snap-in means with the at least one snap-in edge described above, preferably with the two aforementioned snap-in edges.
  • This snap-in opening is then designed to be relatively large in relation to the snap-in hooks, which, however, bear against the snap-in edges with their snap-in projections.
  • the centering projection can advantageously be made for the centering projection to be arranged between two aforementioned latching hooks of a holding means. In particular, it runs, so to speak, through the aforementioned plane of symmetry or along the aforementioned plane of symmetry.
  • the centering projection is preferably at least as high as the latching hooks, preferably higher. It can thus be achieved that the centering projection, as the first region of the holding means, reaches through the latching opening or is connected to the holding tab when the latching connection is established. In this way, the snap-in hooks are brought in correctly and as desired.
  • the centering projection can have an elongated cross-sectional area in a sectional plane parallel to the surface of the carrier plate. So it is elongated, advantageously with a thinner area in the middle and thicker areas on the two ends of said elongate cross-section. Its distance from the snap-in hooks can be a few millimeters, so that these may reach close to the centering projection or even rest against it when the snap-in connection is established.
  • the holding means can have a base part which can be designed as a base plate.
  • a base plate can run parallel to the surface of the carrier plate.
  • the base can rest on the top of the support plate, in particular with its underside.
  • the holding means or the underside of the base part can be glued to the carrier plate either by means of a pasty adhesive to be applied, or alternatively with a type of double-sided adhesive tape with a covering layer over the exposed adhesive layer, which is then to be glued to the carrier plate. Gluing can take place very easily by peeling off this covering layer.
  • At least one fastening projection can protrude downwards from the base part and can engage in a fastening opening in the carrier plate.
  • Two fastening projections are advantageously provided here on each base part, with each fastening projection engaging in a separate fastening opening in the carrier plate.
  • the shape of a fastening opening can correspond to the design of the fastening projection, so that exact positioning also takes place.
  • a fastening projection can be elongate as a type of rail.
  • the longitudinal direction can run in a direction parallel to the surface of the carrier plate.
  • a width of the fastening projection can remain the same, so that simple production is possible and possibly a holding means can be fastened to the carrier plate in any orientation.
  • a longitudinal direction of an elongate attachment projection may be perpendicular to a line from a center point of the heater to the retaining tab get lost. If two fastening projections are provided on the holding means, both are advantageously elongate and, particularly advantageously, both are of identical design. Of course, this also applies to their respective fastening opening.
  • a fastening projection which protrudes from the underside of the base plate or the base part, protrudes in at least one direction parallel to the surface of the carrier plate over the base part, i.e. is also visible from above.
  • This serves as an assembly aid so that the fastening projections of the holding means can be pressed more easily into the fastening openings in the carrier plate.
  • An elongate attachment projection advantageously projects beyond the base part at both ends, for example by a projection of 1 mm to 5 mm. This is sufficient for good visibility, if necessary an assembly person can also better grip and guide the holding means with his hand.
  • two fastening projections are formed on the base part, they can be at a distance from one another. Elongated fastening projections advantageously run parallel to one another. Such a distance can be between 10 mm and 40 mm.
  • the underside of the base part can be glued to the carrier plate, advantageously with an adhesive layer as described above.
  • the underside of the base part should be as flat as possible in this area and should not have any protrusions. Under certain circumstances, cutouts or cutouts can be provided in it, which facilitate production by injection molding.
  • a fit between the fastening openings and the fastening projections can be between 0.1 mm and 2 mm, particularly advantageously a maximum of 1 mm or a maximum of 0.4 mm. Then a very precise specification of the position of the holding means on the support plate is possible, and thus also of the entire heating device.
  • cutouts or depressions are formed on the underside of the base part at a transition between the fastening projections and this underside. These can be recessed in a direction perpendicular to the surface of the support plate. They serve to ensure that when the fastening openings are punched in a metal carrier plate, protruding metal edges or burrs on the fastening openings can extend into them and thus not rest against the underside of the base part. This could cause an inaccurate fit.
  • the fastening openings can thus be punched out more easily and with less effort and precision.
  • the aforementioned adhesive in the form of an adhesive layer for example as a double-sided adhesive tape with a Thickness between 0.1 mm and 2 mm can be left out here if necessary, so that the edges or burrs mentioned do not press into them.
  • a projection can protrude away from the heating device from each retaining tab, in particular from the aforementioned base part of a retaining tab.
  • a projection can be a maximum of 10 mm long or protrude from the retaining tab.
  • Such a projection also makes it possible to guide the holding tab when the heating device is attached to a carrier plate with holding means attached thereto. If the holding means are already snapped into place on the holding tabs and this entire structural unit is then attached to a carrier plate, this is advantageously done by an assembly person grasping the holding means and attaching it to the carrier plate.
  • a carrier plate can advantageously generally consist of metal, in particular aluminum.
  • the fastening openings mentioned are punched out of it, with advantageously only those fastening openings being punched out at the corresponding points for a carrier plate which are necessary for fastening heating devices with holding tabs and holding means thereto.
  • multiple sets or arrays of mounting holes are then not punched out, some or most of which are subsequently no longer needed. Punching is advantageously carried out with a punching direction from the underside of the carrier plate to the top.
  • the support plate, the heating devices and the holding means are provided, each separately at the beginning.
  • adhesive means are advantageously already provided on the holding means, but not yet activated in the sense that, for example, double-sided adhesive tape is also provided with a covering layer.
  • the holding means are first attached to a holding lug of a heating device by latching. Then the adhesives are applied or activated, in particular by peeling off an aforementioned covering layer. Then the assemblies of heating device and holding means are attached to the support plate by pressing the attachment projections into the attachment openings and gluing.
  • the adhesive is first applied or activated to the holding means and these holding means are then glued to the support plate.
  • This is advantageously done for all the holding means that are provided for a single heating device, that is to say particularly advantageously two holding means.
  • the heating device is then fastened to the holding means by latching the retaining tabs to the retaining means, so that the heating device is fastened to the carrier plate. This may be provided for each hob heater in turn.
  • a hob 11 is shown in a simplified sectional view. It has a hob plate 12, which can consist of glass ceramic, for example.
  • a hob housing 15 is fastened to an underside 13 of the hob plate 12 and can be made of plastic, for example, and can have an operating device 17 with operating elements, for example touch switches, and a hob controller.
  • the cooktop housing 15 contains power electronics 34, which can be contained in one or two modules.
  • a support plate 30 corresponding to the support plate according to the invention is provided above the power electronics 34, possibly placed directly on top of it, which is parallel to the hob plate. It is made of aluminum with a thickness of 2 mm, although the thickness and material can also be modified.
  • Induction heating coils 19 are arranged as heating devices on top of the carrier plate 30 and are pressed upwards in a resilient manner by means of springs 29 .
  • the induction heating coils 19 are pressed with a certain force against the underside 13 of the hob plate 12 by the springs 29 for a defined position both in relation to a distance from the upper side of the hob plate 12 on which a pot to be heated is placed and in a direction parallel to the hob plate 12 and carrier plate 30.

From the 9 it can be seen that the underside of the retaining tab 22 runs somewhat above the underside of the rest of the induction heating coil 19 and thus also of the lower part 20 . This is explained in more detail below. Also shown in 2 is a latched to the retaining tab 22 retaining means 40 according to the invention. This is explained in more detail below.
  • the 3 shows the holding means 40 alone in a view at an angle from above, similar to the position shown in 2 is shown.
  • the holding means 40 consists of plastic and has a base plate 42 which is rectangular per se, for example with a thickness of 2 mm to 4 mm. Go from an underside of the base plate 42, especially as shown in the oblique view from below figure 5 1 shows two mounting rails 44a and 44b corresponding to the mounting bosses of the present invention. You stand like that 9 can be seen, approximately with the thickness of the base plate 42 down or are just as thick.

  • This cross-section is approximately bone-shaped, so that the centering projection 54 has a kind of constriction 55 in the middle region, where it is narrower. This can serve to ensure that when the locking connection is established, the locking hooks 47a and 47b are pressed towards one another in accordance with the locking bevels 49a and 49b. Due to the constriction 55, there is a little more space into which they can, so to speak, give way or be pressed further towards one another.
