Definitions

  • the invention relates to an electric cooking appliance according to the preamble of claim 1.
  • a cooking unit with an electric hotplate has become known, in which the electric hotplate is inserted into a preformed mounting plate, and has a punched-out area for the mounting plate, in which the edge zone is shaped into a channel and additionally at the outermost Edge is a small recess for receiving 41 a sealing material.
  • the hotplate is inserted, which is surrounded by a support ring which is tightly attached to the hotplate body, the hotplate is held by the support ring which rests on the edge of the preformed hotplate with a sealing material attached in the channel.
  • the hotplate surface is arranged flat with the built-in plate surface, this arrangement having a wide and deep ring shape around the electric hotplate.
  • the seal is located directly below the support ring of the hotplate and is therefore exposed to high heat, against which sealing materials do not always exist.
  • the flat contact of the support ring with the edge zone of the mounting plate creates a capillary suction effect, causing moisture to get inside.
  • a receptacle for the installation of an electric hot plate which is produced by a drawing or shape punching process and has a specially shaped arch.
  • the edge transition between the mounting plate surface and the arching is provided with a bead ring, which is additionally set by a shoulder to the mounting plate.
  • the support ring of the electric hotplate with line contact lies on this shoulder and protects against the passage of e.g. possibly overflowing cookware.
  • the bead must pass into the recess with a sharp bend. This complicates the manufacture. Furthermore, these troughs have increased leakage currents if water penetrates.
  • An electric hotplate installation is known from US Pat. No. 4,766,290, in which the electric hotplate is inserted into a punched-out mounting plate.
  • the edge zone of these mounting plates has a circumferential bead ring and a surface that then falls towards the recess.
  • a support ring-bowl combination is used to accommodate the electric hotplate for installation in the hotplate.
  • the support ring which tightly surrounds the hotplate body, is connected to a trough-shaped bowl by spot welding. This trough-shaped bowl has the same lines as the support ring in the area of the spot weld and takes over the functions of the short support ring due to the wide edge, at the same time the electric hotplate shields the underside of the electric hotplate from moisture through the trough-shaped bowl.
  • This version is ideally suited for the special purpose of an exchange unit, but is expensive for factory-fitted installation, because despite the trough-shaped bowl, a shielding plate of the hotplate body is attached and, in addition, spot welding is necessary to attach the support ring to the trough-shaped bowl and has a large size Heel between the built-in plate and the hotplate surface.
  • the object of the invention is to provide an installation option for electric hotplates, in which the hotplate surface is arranged only slightly above the level of the mounting plate, has a simple and easy-to-assemble and inexpensive construction and, with good flow security against penetrating moisture, does not fear any impairment of the electrical safety.
  • a very flat hotplate installation can be achieved in which the height between the mounting of the support ring on the hotplate body and the placement of the outer edge of the support ring on the mounting plate can be, for example, less than 5 mm. Because the support ring is at least twice as wide as its height, the transition between the electric hotplate surface and the mounting plate is designed to be fluid. When pulling down e.g. This flat and wide support ring acts as a smooth gliding transition to the built-in plate when boiling over pots, thereby preventing the food from spilling over. The accidents that occur as a result of scalding from spilled food do not occur.
  • the downwardly inclined outer side of the support ring in the installed state can rest directly on the horizontal surface of the mounting plate, as a result of which a very flat installation is achieved.
  • the arrangement of the inclined outer edge of the support ring outside the bead ensures a double security against penetrating cookware.
  • the liquid is already held off by the linear support or the flat contact of the support ring on the outside of the bead, and on the other hand, the bead itself acts as a further obstacle to any liquid that may have penetrated.
  • the support ring arranged on the outside of the bead has an inclined edge zone in such a way that it has a greater slope than the cross-sectional shape of the bead on the outside.
  • a synchronous shape of the support ring and the bead enables the electric hotplate to be held securely and at the same time tightly, with the electric hotplate also being centered toward the trough-shaped recess.
  • the hotplate connection attached to the hotplate body is designed such that in the installed state it is carried out through a recess in the trough-shaped recess.
  • this acts as protection against rotation of the electric hotplate in the installed state.
  • only one recess is necessary in the production of the trough-shaped depression, which is intended for receiving the electric hotplate.
  • the breakthroughs for the anti-rotation bolts, which are otherwise required, can thus be dispensed with, as can the anti-rotation bolts themselves. This considerably simplifies the installation of the electric hotplate and improves its stackability during transport and storage.
  • the inventive wide and flat design of the support ring which covers the annular gap between the electric hotplate body and the bead, also makes it possible to use temperature-resistant seals.
  • the radiating heat energy of the hotplate body is greatly reduced by the large annular gap that is formed between the hotplate body and the bead. This decrease in temperature, which is supported by the poorly heat-conductive, stainless steel sheet, makes the use of seals possible. Since the large annular gap represents a relatively large insulation, additional heat shielding of the mounting plate is not necessary.
  • a seal can be attached between the inside of the inclined outer edge of the support ring and the opposite outside of the bead.
  • This seal can be designed from a sealing compound or in the form of a sealing ring.
  • Fig. 1 shows a very flat installation of an electric hotplate 2 in an electric cooking device 1.
  • a trough-shaped recess 5 of a mounting plate 4, such as. B. a hob or a recess is an electric hotplate 2 and is surrounded by a support ring 3, which is substantially continuous. This covers an annular gap 11, which is formed between a hotplate body 9 and a peripheral surface 7 of the trough-shaped recess 5.
  • the electric hotplate 2 has a hotplate surface 33 with an annular shoulder 34 which runs around towards the edge and which has a semicircular, downward course from the hotplate surface 33.
  • This ring shoulder 34 projects beyond a downward edge 10 of the hotplate body 9, the shoulder width is smaller than the shoulder height.
  • the underside of the annular shoulder 34 forms a right-angled shoulder 32 to the downward-facing surface of the circumferential edge 10.
  • the annular shoulder 34 with the shoulder 32 is used to attach the support ring 3, which acts on the hotplate and against the tension and weight forces Mounting plate 4 must be supported, takes up.
  • the support ring 3 has the cross-sectional shape of an oblique, flat inverted U. Its essentially vertical inner section 31 is pressed onto the upper outer surface of the outer edge 10 of the hotplate body 9. An adjoining, essentially flat, radially outwardly extending intermediate section 50 is supported on the underside of the shoulder 32 and, at a certain distance from the outer edge of the shoulder 32, is inclined at an angle of 10 * to 30 °, preferably 20 downward sloping middle section 13 over. This is followed by a steeply inclined outer edge 12, which rests with its lower edge 44 on the mounting plate 4.
  • the support ring 3 has a relatively wide and flat shape. Its height, measured from the intermediate section 50 to the edge 44, is less than 7 mm, preferably 4 to 5 mm. In contrast, the width of the support ring between the outer edge of the shoulder 32 and the edge 44 is between 10 and 25 mm, preferably 15 mm. It should be at least twice, preferably three times the height.
  • the support ring 3 thus has a flat shape which covers the annular gap 11 and, due to its small material thickness of 0.4 to 0.5 mm, is also relatively elastic, so that, like a plate spring, it forms an elastic reserve during tensioning, the load fluctuations and in particular Compensates for differences in thermal stress. It forms a flat and flowing transition, which allows cooking vessels to be easily pushed over from the hotplate surface 33 onto the mounting plate 4.
  • the mounting plate 4, with its recesses 5 provided for a plurality of hot plates, is produced from a coherent sheet by a drawing or stamping process. It can consist of stainless steel, enamelled steel sheet or the like.
  • the depression 5 merges with a bulge 8 in the flat surface 54 of the mounting plate 4.
  • the bead 8 lies within the outer edge 12 of the support ring 3, has a simple, hump-shaped cross section, which has a steeper slope on its outer side 15 than the side directed towards the recess 5, which merges into the peripheral surface 7.
  • This circumferential surface 7 extends to the trough bottom 6 through a straight, continuously descending course.
  • the angle ⁇ which is included between the horizontal of the mounting plate 4 and the circumferential surface 7, is between 55 and 80 °, which has been found to be advantageous that the circumferential surface 7 is arranged at an angle of 65.
  • the trough-shaped depression 5 consisting of the peripheral surface 7 and the bottom 6 essentially has a circular bottom shape.
  • the circumferential circumferential surface 7 merges with a rounding into the trough bottom 6, which slopes slightly towards the center of the depression 5.
  • a circular profile 35 is formed in the interior of the trough bottom 6.
  • This profiling 35 which stands out slightly from the trough base 6 and has an opening 19 in the middle for the implementation of a fastening means 17, serves to stiffen the trough bottom 6.
  • the fastening means 17 is a screw bolt screwed into a casting eye 45 of the hotplate body , which protrudes through the opening 19 and clamps the electric hotplate 2 to the mounting plate 4 with a nut resting under the trough bottom 6.
  • Openings 20 arranged outside the profiling 35 preferably three distributed over the circumference, serve for the removal of any liquid that has penetrated into the interior of the recess or has been formed by the formation of codensate.
  • the electric hotplate 2 has a heater made of resistance wire coils, which are inserted in spiral-shaped grooves in a ceramic embedding material on the underside of the hotplate body 9. Pins 52 protrude from the investment material, to which massive connecting lines 23 are welded.
  • the terminal block 24 is seated in an opening adapted to its outer shape and is attached to it by folding sheet metal tabs.
  • the opening 18 for a hotplate connection 16 essentially has a similar shape, corresponding to the cross section of the connecting block 24, the recess being designed in such a way that a small gap is formed between the connecting block 24 and the opening 18. This ensures a safe insertion of the electric hotplate into the trough-shaped depression and the hotplate connection 16, which must be carried out through the opening 18.
  • the side surfaces 39 of the opening 18, which are opposite the narrow outer sides 22 of the substantially rectangular opening 18, the corners of which are round, serve as an anti-rotation device in which the outer surfaces 22 of the connecting block 24 rest against the side surfaces 39.
  • the solid hotplate connecting wires 23 are guided in the connecting block 24 through the opening and the part of the hotplate connecting wires 23 protruding from the connecting block 24 are bent at an angle on the outer end face 25 of the connecting block 24.
  • the shielding plate 36 is circular and flat, lies against the lower edge of the edge 10 of the hotplate body 9 and is attached to the central eye 45 for the fastening means 17.
  • a hood 21, which is attached to the trough-shaped recess 5, is provided in order to isolate this hotplate connection 16, which protrudes from the opening 18, a hood 21, which is attached to the trough-shaped recess 5, is provided.
  • This hood 21, which is preferably made of sheet metal, encloses the hotplate connection 16 and flexible connecting lines 26 which are led out of the hood 21 laterally.
  • the hood 21 can be connected to the bottom 6 by a snap connection or a screw connection. It is also possible to provide them with a flag-like extension which is screwed on with the fastening means 17.
  • the hood 21 has a recess in order to carry out the glass-fiber-insulated, flexible connecting lines 26, which are guided in an insulating block 28 and have end sleeves 27 at their ends.
  • the insulating block 28 is attached laterally to the connecting block 24, the wire end sleeves 27 being tangent to the hotplate connecting wires 23 and being welded.
  • the insulating block 28 as can also be seen in particular from FIGS. 3 and 4, has an elongated shape and has openings corresponding to the number of connecting lines 26, into which the end sleeves 27 are inserted next to one another.
  • the result is a comb-shaped structure with wire end sleeves 27 lying next to one another in the exemplary embodiment 4.
  • they can be placed like a comb between the ends of the connecting wires 23 and pushed sideways, where they can easily be welded to them with a welding gun.
  • the elongated insulating block 28 has on its upper side an angular recess which interacts with the lower, outer edge of the connecting block 24, so that the insulating block 28 practically forms an outer lower extension of the connecting block 24.
  • a spacer made of insulating material is thus formed, which practically excludes contact by surrounding sheet metal surfaces, for example the hood 21. Due to the arrangement of the hood 21, the hob, which mainly consists only of the mounting plate 4, is also electrically closed at the bottom, so that it can be installed directly without further lower covers.
  • the flexible connecting lines 26 lead to a common terminal block or switching or regulating devices, via which they can be connected to the household electricity network.
  • the openings 20 for the escape of moisture are preferably arranged at the lowest point of the trough bottom 6, the surface which is formed by the peripheral surface 7 up to these openings 20 being inclined such that the moisture can flow off to the openings 20 and escape.
  • the openings 20 are preferably arranged outside the profiling 35 so that the moisture which may form on the profiling and on the trough bottom can run off towards the openings 20.
  • the opening 19 is made in the form of a circular recess through which the fastening means 17 is passed.
  • the simple design of the trough-shaped depression, as well as the arrangement of the openings 18, 19, 20 for fasteners, liquid outlet and hotplate connection is clear. This also results in a simple and safe installation for installing the electric hotplate 2 in an electric cooking device 1.
  • FIG. 3 shows a section of a variant for the design of the opening 18 for the implementation of a hotplate connection 16. It can be seen that this recess is formed by a horseshoe-shaped cutout in which a tab 37 is formed by a gap 40 which runs parallel to the side edges 39. In a connecting line formed between the side edges 39, two slots 38 are provided, which result in a desired bending line 41 between the two ends of the gaps 40 when installing and removing the electric hotplate 2, the tab 37 is easier to bend.
  • this tab 37 When mounting the electric hot plates on the mounting plate for the first time, this tab 37 remains in the extension of the base 6, i. H. it is not bent (Fig. 4a). It can be seen that the opening 18 is only slightly larger than the outer dimensions of the terminal block 24.
  • the terminal block 24 projects relatively far down from the end plate 36 so that it can protrude through the opening 18 of the bottom 6 and together with the Breakthrough 18 forms an anti-rotation device for the electric hotplate 2. Therefore, the usual anti-rotation bolts of the electric hotplate 2.
  • the connecting block 24 is securely fixed to the lower shielding plate 36 by inserting and bending tabs. Furthermore, the large length of the connecting block also reduces the temperature at the ends of the connecting wires 23, so that the flexible connecting lines 26 and their ferrules 27 can be produced from copper.
  • the electric hot plates 2 are usually placed in reverse on a device and then the mounting plate 4 is placed over it from above.
  • the terminal blocks 24 not yet provided with the connecting lines 26 can reach through the opening 18. Only then is the connection made, the arrangement of the wire end sleeves 27 in the insulating block 28 ensuring that the connecting lines 26 cannot be interchanged.
  • FIG. 4b shows the disassembly of a hotplate in the event of a repair.
  • the welding to the flexible connecting lines 26 is not released and, despite the smaller opening 18, the entire arrangement can be expanded by bending the tab 37.
  • a replacement hotplate already has the welded-on flexible connection ends.
  • the tab 37 is pressed down by the electric hotplate when it is reinstalled and can optionally be re-bent by hand.
  • the downwardly inclined outer edge 12 adjoining the central section 13 of the support ring 3 lies linearly with the outer lower edge 44 on the horizontal plane 54 of the mounting plate 4 outside the bead 8, and just outside the upwardly extending outside 15 that forms a flank of the bead 8.
  • the slope of the outside 15 of the bead 8 with respect to the horizontal of the mounting plate 4 is less than the slope of the outer edge 12 of the support ring 3. This results in a wedge-shaped space between the inside of the outer edge 12 of the support ring 3 and the outside 15 of the bead 8.
  • a seal 30 in the form of a sealing compound can be attached in this intermediate space.
  • the embodiment according to FIG. 6 essentially corresponds to that according to FIG. 5, the transition from the horizontal surface of the electric hotplate 2 to the outside 15 of the bead 8 being formed by a small, circumferential groove 14.
  • the groove 14 is semicircular in cross section and has smooth round transitions from the horizontal surface of the mounting plate 4 to the outside 15 of the bead 8.
  • the bead 8 is changed in its apex in this embodiment to the extent that it has a narrow, flat upper surface. Due to this wider design of the bead 8, the outer side 15 bears against the inner side of the outer edge 12 of the support ring 3. When installing the electric hotplate 2, the outer edge 12 of the support ring 3 automatically adapts to the outer cross-sectional shape of the bead 8.
  • the electric hotplate 2 is centered towards the trough-shaped depression and can also be adjusted in height, as shown in FIG. 6 by the dash-dotted outer contour. Due to the abutment of the outer edge 12 of the support ring 3 on the outside 15 of the bead 8 and by the ring-shaped synchronism of the bead 8 and the support ring 3, a flat, tightly matched connection is achieved, which ensures high throughput security. Through the recess 5 of the channel 14 a flatter installation of the electric hotplate is made possible because the outer edge 12 of the support ring 3 can be moved to the bottom of the channel 14, which is up to a few millimeters lower than the horizontal plane of the mounting plate 4. This design can also be advantageous if the lower edge 44 rests in the channel 14.
  • FIG. 7 essentially corresponds to that according to FIG. 5, a variant of the outer edge 12 of the support ring 3 being shown.
  • the downwardly inclined outer edge 12 adjoining the central section 13 has at the end of the outer edge 12 an outwardly curved edge zone 29 which is supported flatly on the mounting plate 4.
  • This flat arrangement allows the edge zone 29 to be displaced with respect to the horizontal plane of the mounting plate 4, as a result of which the electric hotplate 2 is supported by the support ring 3 in a slightly resilient manner is.
  • Another feature of the flat-lying edge zone 29 is that this ensures better heat transfer to the mounting plate 4 and thus the temperature occurring in the outer edge 12 of the support ring 3, in particular in the edge zone 29, is further reduced.
  • FIG. 8 a combination of the exemplary embodiments from FIGS. 6 and 7 is shown, the shape of the support ring 3 described in FIG. 7 being arranged in combination with a channel 14 which is similar to that described in FIG. 6 .
  • the channel 14 is shaped differently and has a flat bottom on which the edge zone 29, which is supported flat, remains displaceable relative to the channel bottom 43.
  • the transition from the horizontal surface 54 of the mounting plate 4 to the channel bottom 43 and the transition to the outside 15 of the bead 8 is carried out smoothly by mean radii.
  • FIG. 9 a variant of the support ring 3 from FIG. 1 is shown, the basic structure of which corresponds to that of the support ring 3 described in FIG. 1.
  • the intermediate and central sections 50, 13 shown in FIG. 1 are formed into a single flat central section 13, so that the support ring 3 has the shape of an inverted, wide U. This configuration of the support ring 3 results in an even flatter installation of an electric hotplate 2 in a mounting plate 4.
  • a seal can additionally be provided, for example a pasty seal 30 in the channel 14.
  • the electric hotplate 2 can also be used universally because of its wide support ring 3.
  • the otherwise necessary intermediate ring can be omitted.
