Definitions

  • the invention relates to an electric hotplate according to the preamble of claim 1.
  • the object of the invention is to provide an electric hotplate according to the preamble of claim 1, which maintains the evenness of the cooking surface under all operating conditions with low heat capacity and good efficiency when parboiling and in the stationary state.
  • the hotplate body no longer has ribs on the underside, between which the heating elements are embedded, so that it loses its mass and heat capacity as a result. Furthermore, it can now also be produced differently than in the sand casting process, for example from sheet metal, so that the plate wall thickness can also be reduced.
  • the relatively thin tubular heaters used have a much lower mass than the corresponding embedding in the previous hot plates and the tubular heaters do not need to be arranged close together, but can be spaced apart.
  • the embedding for the heating coils in the tubular heating elements is normally compressed to such an extent by stretching and rolling processes that their thermal conductivity is better.
  • the distance of the heating coil according to the invention from the cooking surface is significantly smaller (approximately 3.5 mm compared to 6 mm in the previously customary hotplate), so that despite a further intermediate limb, namely the jacket of the tubular heater, a much more direct heat transfer to the cooking surface is possible.
  • the resilient pressure of the tubular heating element on the underside of the hotplate ensures a permanent system without annoying noises when heating or cooling and the interposition of the heat-resistant insulation ensures good efficiency even when stationary.
  • an electric hotplate 11 which has a hotplate body 12, which consists of a circular disc, preferably made of stainless steel, which has an outer edge 13 and an inner edge 14 which are directed substantially vertically downwards.
  • the inner edge 14 includes an opening 15 which is intended to accommodate a conventional temperature sensor 17, indicated by dashed lines, in the form of a sensor box which is resilient and can be pressed against the saucepan base and is filled with expansion fluid.
  • a support sleeve 16 is pressed into the opening, which limits the upward movement of the sensor socket with an upper flange and defines it with limited mobility with a lower flange.
  • the outer edge 13 is relatively thin after a rounded transition and has a triangular circumferential notch 18 (FIG. 3) into which an upper case edge 19 is snapped in the form of a profiled ring made from a thin stainless steel sheet.
  • the cross section of the rim is an inverted, asymmetrical, relatively flat, rounded V.
  • the annular space between the outer and inner edges 13, 14 is closed by a base plate 20, which is circular and in its central region with the Support sleeve 16 is connected, for example, by welding.
  • the upward-facing and provided with projections 22 outer edge 23 of the base plate lies in a manner explained later with reference to FIGS. 9 and 10 on the lower edge of the edge 13, is supported there and is centered on the edge.
  • a spring part 24 rests on the base plate, which has the shape of an eight-pointed star with a central hole in the example shown (FIG. 2) and consists of a spring plate.
  • Eight spring elements 25 in the form of upwardly bent leaf spring arms project outward from the annular hub as rays of the star.
  • the bottom plate 20 is provided with stiffening beads in such a way that the spring part and the spring elements each lie in the lower part of the bottom plate.
  • the spring elements 25 press in the central region of the heating ring zone formed between the inner and outer edge, ie with respect to the entire hotplate, relatively far out on a support disk 26, which lies as an annular, flat sheet metal disk in the annular space 27 enclosed by the base sheet 20 and the underside an insulation covering 28, which consists of two layers in the example shown.
  • the lower, thicker layer consists of a pressed bulk insulating material, preferably a fluffy to powdery A1 2 0 3 , which is pressed to form an essentially flat washer. This material has a very high thermal insulation ability, but is not mechanically very strong.
  • a glass fabric for example, can cover the top and / or bottom as a support layer.
  • a second insulating layer 30 is placed over this first layer 29, which consists of a fleece made of an inorganic fibrous insulating material. These are fibers made of A1 2 0 3 , which combine good mechanical strength with high heat resistance.
  • the insulation 28 consisting of the layers 29 and 30 is pressed by the spring elements 25 against the underside of tubular heating elements 31 and presses their flattened upper side against the underside of the hotplate body.
  • the hotplate body is as flat as possible on the upper side to form a cooking surface 32.
  • the tubular heaters consist in the usual way of a metallic jacket made of stainless steel of very small thickness (less than 0.4 mm, preferably 0.3 mm), in which helical heating resistors 33 are located in highly compressed, electrically insulating investment material.
  • the jacket 34 of the tubular heater is triangular shaped to create the upper contact surface and has width dimensions of 4 mm or less, so that there is a very flexible heater that is bent into the shape of a spiral ring and under the pressure of the spring element 25 and Intermediate layer of insulation with good thermal contact is pressed against the underside of the hotplate body.
  • the heating resistor consists of a spiral which has downward bends 35 in the inner and outer region of the annular space 27, to which the hotplate connections 36 are welded.
  • a temperature limiter 37 is interposed at a connection and senses the underside of the tubular heater.
  • the connections lead to a connection piece 38 which is attached to a laterally protruding connection plate fastened to the base plate and is to be connected there with the connection lines coming from the switch or controller.
  • the heating resistor can also be designed as a tandem spiral, i.e. two coaxial spirals of the same diameter, which are electrically connected in parallel. They have a larger heat-emitting surface and can be bent with a very small bending radius.
  • the support disk 26 can be ribbed to increase the rigidity.
  • An electric hotplate is created which has a thin and possibly corrosion-protected hotplate body with thickness dimensions of less than 3 mm and to which the underside flexible and easy to put on tubular radiators are pressed over an effective insulation.
  • the heated annular space 27 is closed, so that no heat losses are to be feared even by convection. Due to the good contact of the tubular radiators, which are relatively far apart, the distance from one another being around 1 1/2 times the width dimensions, the temperature in the tubular heater is kept relatively low, so that it does not tend to burn out.
  • the spring elements have sufficient spring travel to ensure that they are pressed against the insulation even if the insulation compresses somewhat during operation.
  • the hotplate can be produced using less material and operated with better efficiency than other hotplates that are comparable in terms of their utility value.
  • the embodiment according to FIG. 4 differs from that according to FIGS. 1 to 3 in that the hotplate has no middle temperature sensor, so that the hotplate body 12a has no middle opening, but is only slightly embossed at this point, so that the annular, flat surface Cooking surface 32 is contrasted.
  • the same parts have the same reference numerals.
  • the hotplate body also has no inner edge, so that the inner annular space 27a encompasses the entire underside of the hotplate.
  • the design of the outer and upper rim 13, 19 is the same as in FIG. 1.
  • the bottom plate 20a extends over the entire underside of the hotplate and is not only supported but also fastened in the area of the outer edge 13. Parallel to it is at a distance from it a support disk 26a, which is a circular sheet metal disk and at the same time assumes the function of the spring part, in which, in the present example, radially inwardly directed tabs or arms are punched out and bent downward are and form the spring elements 25a, which are resiliently supported on the bottom plate 20a.
  • the support disk 26 presses evenly on the insulation 28a, which in the present case consists of a single layer of pressed inorganic insulating material, which is provided on the top with a coating 39 which protects the insulation from the thermal and mechanical action of the tubular heating element. It can be an asbestos fiber layer or a ceramic layer.
  • a part is saved through the use of the support disk for cushioning, although in this case the support disk is to be produced from a spring material.
  • the hotplate attachment is also shown.
  • the upper lower edge 19 lies with its outer lower edge on a step of a hotplate or hob 40, which lies in the region of an obliquely upward overflow or coiling edge 41 which surrounds the installation opening 42 of the hotplate.
  • the cooker or hob is closed at the bottom by a cover plate 43 which is supported on the underside of the hotplate.
  • the hotplate is held down on this cover plate, the function of which could also be taken over by a corresponding bracket in a different type of stove, by means of several, preferably three fastening elements or tabs 44, which are shown in detail in FIGS. 5 and 6. They are attached to the outside of the edge 13 by spot welding and project vertically downwards as narrow strips. At their end they have a protrusions 45 formed by a barb-like bend, which protrude through openings 46 in the base plate 44 and through corresponding, but offset openings 47 in a bow-shaped leaf spring 48. This is attached on one side to the cover plate 43 and is also supported on the other side to increase the spring force. The opening 47 is in the Central region of the leaf spring 48.
  • the offset of the openings together with the barb-like slope of the projection 45 when the tabs 44 are inserted through both openings causes the tab to bend somewhat elastically until the projection has reached the underside of the leaf spring 48 . In this way it is ensured that the projection 45 is held securely on the leaf spring, so that accidental loosening is impossible.
  • the hotplate is placed on until the upper case edge 19 rests on the corresponding point on the hotplate and then the spring 48 is pressed upwards until the projection 45 has engaged. Since only one edge of the opening is involved in the latching process (in FIG. 5 the right edge of opening 46 and the left edge of opening 47), the openings could also be replaced by corresponding edge arrangements.
  • the fastening elements 44 also form the anti-rotation device for the hotplate.
  • the support and centering of the base plate 20a on the edge 13 can still be seen from FIG. The edge is taken up in an angular shape of the floor panel.
  • FIG. 7 an electric hot plate is shown, which corresponds to that of FIG. 1 except for the insulation.
  • the insulation 28b shown here consists of a pressed inorganic insulating material, for example an Al 2 O 3 fiber fleece, into which a reinforcement 49 in the form of a wire mesh made of stainless steel wire is pressed in on the top and bottom to such an extent that it is firm with the insulation is connected, but forms the outside of the insulation. This is best done when the insulation is wet-pressed.
  • the reinforcement which could also consist of a different metal structure, for example a sheet metal provided with corresponding punchings, forms an extremely hard-wearing, rigid insulating part which nevertheless forms very good thermal insulation.
  • the tubular heater are only punctiform on the reinforcement. Nevertheless, the pressure force is transmitted safely and the spring elements 25 can act directly on the underside reinforcement without a supporting disk.
  • the base plate 20b is fastened by flanging the support sleeve 16.
  • FIG. 8 shows a variant of the hotplate fastening on the cover plate 43c.
  • a tab is punctured on the inside of the edge 13, which protrudes through openings in the base plate 20c.
  • This tab 44c is inserted through an opening in the cover plate 43c and secured by turning the sheet metal tab.
  • the twisted end forms a tab 50 on which a plug of an earth line can be plugged.
  • Fig. 9 the support of the bottom plate 20c on the lower edge of the edge 13 is shown greatly enlarged in detail.
  • the base plate In the area of its outer, upward-facing edge, the base plate has, in places, pronounced projections 22 on which the lower edge of the edge 13 is supported. The rest of the upward edge 23 of the base plate projects with the inner surface of the edge 13 for centering.
  • FIG. 10 An insulation 28d is shown in FIG. 10, which has a pyramidal profile on its upper side.
  • the profiling ensures that the tubular heating elements only abut in a largely punctiform manner and that any manufacturing inaccuracies in insulating body production are compensated for by partially pressing in the tubular heating elements.
  • the point system also reduces heat transfer.
