Description

Built-in hob.

  The present invention relates to a built-in hob with a worktop, comprising a hob, in particular glass-ceramic, provided with several cooking stations or fireplaces, heating devices for the latter as well as operating elements and indicated on the surface of the table, preferably on its front face. In the known hobs of the aforementioned type, the surfaces or hobs and the control devices with operating and indicating means associated therewith are provided as separate building elements which require separate mounting locations for example inside a kitchen cabinet The control device of the various hobs of the hob is generally integrated into the control box of a cooker placed under the hob In the absence of such a hob range, it is necessary to provide a special control box that should also be installed directly below the hob in the kitchen unit to obtain direct connections between the operating elements,

  indicating elements and hobs of the hob.

  In other known hobs, the actuators are certainly placed in the area of the upper face of the table, for example laterally next to the hearths, but these actuators protruding from the cooking place or hearths do not are not easily discernible and are very troublesome when using the cooking surface Moreover, in these hobs, it is also expected for the control devices housing that project from the underside of the worktop carrying the cooktop so you can not use the area below the hob to accommodate other appliances

  freestanding or built-in appliances, parts of furniture or the like.

  In household appliances of this type, in particular: cooktops or stove, the execution of repair work is also relatively difficult since the electrical and electronic control and regulation devices necessary for the operation of the appliance are mounted in a control enclosure To proceed with the repair, it is first necessary to open for example the front of the stove and lift the work table that is applied to it, and even then it remains difficult to perform repair work in the extremely narrow control enclosure. Finally, in known ceramic hobs, it is usual (German patent application 28 19 118)

  to install the ceramic glass plate in a metal frame

  It can be fixed by means of a heat-stable glue and a relatively permanent elasticity. In another known embodiment (German Utility Model 1,800,892) all the electrical switches necessary for the control of the plates are located right next to a steel cooktop in a panel located approximately in the plane of the hob, this panel being part of

  integral part of the hob placed on the worktop.

  To receive the heating elements of the various hobs and the electrical control devices that are associated with the electrical switches, the hob has on its underside a cup-shaped casing projecting below the work plane In cookers of this type, the difficulty also lies in the fact that, in the hob area, no other appliance, drawer or the like can be installed directly beneath the worktop, since this part of furniture for installing the hob is at least used to receive the control device

  of this hob In these appliances, the power supply unit

  supply of low-voltage electronics) and the

  connection to the network are placed in an additional box

  shut up that needs to be placed outside in a cabinet and

  connected by a cable to the control device.

  The object of the present invention is therefore to provide a built-in hob of the aforementioned type which is compact, provided with all the devices necessary for its operation and sufficiently flat to require only a very small mounting space and in particular that the space below the hob can remain available for other uses Despite this compact construction, the invention also aims to make the control and control subassemblies more accessible than in the known embodiments. Moreover, it is necessary that the actuating and indicating devices are arranged in a prominent position and that the different foci they control are clearly visualized, although the organs must not be any hindrance to the manipulations to be carried out overhead. table of

cooking.

  This result is achieved according to the invention in that in a housing, preferably in the form of a die casting and carrying the cooking plate

  as well as maneuvering and indicating devices, is also

  the control device associated with the actuating and indicating members and with the heating devices, and that the housing has a height established so that it does not exceed, or at least not substantially, the limiting surface lower and preferably also the

  upper limiting surface of the worktop The design

  The special feature of the stacker, preferably one-piece, has the advantage that all the parts necessary for the operation of the hob are combined in a one-piece module. Thanks to the flat construction of this module,

  the area below the cooktop remains

  free installation so that it can be installed, that is to say directly below the hob, not only

  other devices, but also drawers or the like.

  The tilt of the dashboard that connects to the front of the hob gives perfect visibility and

  great ease of operation of the hob.

  The installation of all the devices necessary for

  cooktop operation as well as the aesthetic effect

  The latter may be improved according to another feature of the invention by matching its overall length at least approximately to the depth of two laterally bordering work planes, between which it is inserted and whose The distance from one to the other is also the width of the hob. In such a case, the control device is advantageously installed below the dashboard and its connection block and power supply in the dome-shaped projection For the control device, it is preferable to use very bulky electronic subassemblies. , while the bulky connecting and feeding block is placed in the rear projection This dome-shaped projection in no way affects the appearance of the cooktop as the kitchen worktops are usually delimited at the back by ledges and that the dome-shaped projection is placed in the alignment of its edges between the planes of

adjoining work.

  In the embodiment according to the invention for the execution of the repair work, it is sufficient to remove as a unit the control subassembly of the hob, the support acting as the outer cover of the sub-assembly. control assembly rendering unnecessary any particular wall to be undone in case of repair It is particularly advantageous in such a case to place the control devices on

  easily interchangeable connection boards.

  On the support, mounting brackets are preferably provided in which the different connection plates can be easily plugged in, these mounting brackets can be made in such a way that the fixing can be adapted to

  different heights of the subassemblies.

  The invention provides the possibility of producing the control subassembly in the form of a flat functional block easily detachable from the apparatus so that for example on the

  decks, not only the electronic modules

  control or control electronics and control devices, but also the adjustment devices, for example the actuators This unit is inserted as a unit in the hob, for example below a plane dashboard, the operating members being placed in a position which coincides exactly with the control stations of the dashboard, for example by crossing openings in the latter in case of buttons, keys, or slider switches, or by coming elastically on the underside of the dashboard in case of so-called touch switches

  with capacitive signal transmission.

  Thanks to the special design according to the invention of the hob, in particular at the oblique position of the

  dashboard, the latter is located well in

  this on the front of the table without exceeding

  the surface of the hob, so that

  control units are no obstacle when

  the use of the hob Finally, the divi-

  support into a housing for the communication device

  mande and a portion of frame for the hob guarantees, despite the compact construction, the absence of any reciprocal interaction eg thermal

  different units of operation.

  An important feature of the built-in hob according to the invention is furthermore the provision

  and the particular distribution of electrical subassemblies

  or electronic inside the open flat frame

  on both sides and allowing an extremely

  mement flat The fastening elements of the subassemblies are indeed arranged here so that, given the extremely flat construction of the hob it

  it is possible to obtain for the subassemblies a

  optimum position placing them in the required position to best adapt to the actuators, for example the touch switches on the dashboard Despite the superposition of some electronic subassemblies, for example connection plates, one can thus achieve a housing for the control device that does not exceed

  not a height of 4 cm for example.

  The invention will be better understood with the aid of the description of embodiments taken as examples, but not limited to, and illustrated by the accompanying drawings, in which: FIG. 1 is a perspective view of the hob insert according to the invention inserted between two work planes;

  available, for example for the installation of a drawer 18.

  The frame 4 is made so that the dashboard 7 protrudes from both sides in the form of cheeks 19 section 6,

  obliquely inclined, of the dashboard 7.

  The exemplary embodiment according to FIG. 2 differs from that of FIG. 1 by the design of the dashboard.

  and the arrangement of maneuvering organs and indicators.

  Here, the dashboard 20 is certainly also bent and

  with an oblique section, but in the area of this section

  In the exemplary embodiment according to FIGS. 8 to 11, the reference 250 generally designates a support made

  in the form of a die-cast aluminum part.

  As shown in particular in FIGS. 8 and 11, this support consists essentially of three main sections located one behind the other in the

  meaning of the length (arrow A, figure 8), namely a

  251 for a control device 252 as well as for a dashboard 253, a frame portion 254 for receiving a flat hob 255 made in the form of a glass-ceramic plate, and a rear boot portion 256 which, here too, projects dome-shaped above the upper limitation of the hob 255 and forms the sides of a housing 257 with the exception of the back side 6 and the bottom. These precipitated sections form elements constituent parts of the

  In FIGS. 8 to 11 it can be seen that the door

  254 has on its periphery a sole 258 which, with respect to the upper edge of the support 250, in the

  housing area 251, is lowered approximately

  The frame portion 254 also has on its periphery a vertical flange 259 connected to the cooking plate 255 so that it fits exactly (flush with the flange 258) and is, for example, stuck on its surface. 258 on the frame portion 254, just on the outer face of this vertical flange 259, are formed fixing bosses in

  form of nipples 260 and 261 which have different

  On the pressure plate 266 there are mounted plate-shaped compression springs 267 which are intended to lift the heaters 262 to keep them pressed against the cooking plate 255 At a distance below the pressure plate 266 is placed a thermally insulating plate 268 also in the form of a bowl which is also fixed by means of screws on the fixing studs 260 This thermally insulating plate 268 has no direct contact with the pressure plate 266 and is preferably covered with an insulating varnish which increases the thermal insulation effect and, in case of possible contact with the thermally insulating plate

  with the sheet or the like, prevents the so-called "sticking" effect.
