Definitions

  • the invention relates to a switch for connecting additional heating to hot plates and / or hot plates with a rotatable setting element for the power or temperature.
  • the object of the invention is to find a simpler solution here, i.e. To create a switch of the type mentioned, which allows the additional heating to be switched on with the simplest operation.
  • the setting element belongs to cinem Control device that regulates or controls the output of the main and additional heating elements.
  • the switching element can preferably have a snap switch operated by the adjusting element with stable limit positions, which closes a contact for the additional heating in one of the limit positions.
  • This snap switch is thus actuated by switching elements, for example cams, which are, for example, adjacent to the zero position of the switch and, when deflected therefrom, press the snap switch in one direction or the other.
  • the setting element belonging to the regulating or control device according to the invention can only be rotated by a certain angular amount of less than 360 °.
  • the invention proposes that the switching element in a housing which can be attached to the setting element contains a driver which can be connected in a rotationally fixed manner to the setting shaft and which engages in a recess which allows a limited rotational movement in a cam disk which is arranged in the housing and which rotates and which switches the switching contact or the switch contacts are actuated.
  • the user in order to switch on the additional heating, the user only needs to turn the switch from the zero position to a certain angular position at which the additional heating is switched on, and then turn the switch back to the desired value. If he wants to set a certain output without switching on the additional heating, he turns the switch from the zero position directly to the desired value.
  • the switching element can preferably be designed as an attachment switch for a power control device or a temperature controller.
  • the housing of the switching element has on its side facing away from the housing of the adjusting device a fastening device which corresponds to the fastening device of the power control device or the temperature controller.
  • a particularly simple actuation of the switching contact or the switching contacts is possible if the cam disk has a switching cam which has a recess in the region of its apex which serves to produce a certain detent in the switched state.
  • the switch can particularly preferably be used in the case of a heating element for a glass ceramic cooking appliance with a support recess arranged below a glass ceramic plate be arranged in the electrical heating resistors in the central region of the carrier trough in the form of an essentially circular main heating element, with additional switches arranged by the switch on both sides of the main heating element, which form the entire heated area to form an elongated rectangle , complete with rounded corners if necessary, can be activated.
  • the symmetrical arrangement of the main and additional heating elements is visually appealing and makes sense from the point of view of operation, since there can be practically no confusion between the main and additional heating elements.
  • the heat distribution is very even, so that there are no overheated spots during heating.
  • the glass ceramic cooking appliance 11 shown in FIG. 1 has a glass ceramic plate 12 covering a total of four cooking zones, which is enclosed by a frame 13 and forms a recessed recess which or the like in an opening in kitchen furniture. can be used. Under the glass ceramic plate, heaters are provided for three essentially circular or ring-shaped hotplates 14, which are marked on the top by etching, coloring or the like. It is also a
  • Cooking area 15 is provided which, as can be seen from FIG. 1, has a central S-shaped heated zone and adjoining lateral heated zones. These are identified on the top by a corresponding marking or structure 16.
  • the heating 17 for the hotplate 15 is shown in detail in FIGS. 2 and 3. It consists of a carrier shell 18 made of heat-resistant insulating material, for example as a molded body made of ceramic fiber, which lies in a sheet metal shell 19 (FIG. 3). It is pressed against the underside of the glass ceramic plate 12 in a manner not shown with its outer edges pointing upwards.
  • a carrier shell 18 made of heat-resistant insulating material, for example as a molded body made of ceramic fiber, which lies in a sheet metal shell 19 (FIG. 3). It is pressed against the underside of the glass ceramic plate 12 in a manner not shown with its outer edges pointing upwards.
  • the carrier shell 18 is divided into three regions 21, 22, 23, which are thermally separated from one another and in particular shielded from radiation, by webs 20 reaching up to the glass ceramic plate.
  • the central region 21 is circular and has at its bottom, i.e. at a substantial distance from the glass ceramic plate, grooves 24 which are arranged in a spiral shape such that the two ends are on the outer circumference.
  • a heating resistor 25 in the form of a wire coil is inserted into these spiral-shaped grooves.
  • the two areas 22, 23 adjoin the round central area 21 on both sides opposite one another and complement the round central area to form an elongated square with generously rounded corners. Accordingly, the two outer regions 22, 23 have outer and side edges connected to one another by rounded corners and a round inner edge narrowing their central region.
  • 24 heating resistors are inserted in the grooves.
  • the grooves run spirally from the inside to the outside and have essentially a B-shape with a straight side, two adjacent curves and one the inward curved side opposite the straight side.
  • the heating resistor in the area 22 directly adjoins that of the area 21 and projects through an opening in the web 20, while the heating resistor in the area 23 is inserted independently of the others.
  • three heating elements are created, namely a central, essentially circular main heating element 27 and two additional heating elements 27 adjoining them laterally. They can be connected by connecting pieces 28 and corresponding connecting lines 29 such that the main heating element 26 is independent of the addition -Heating elements can be switched on.
  • a temperature limiter 30 is for. B egrenzung the temperature at the underside of the glass ceramic plate is provided. It consists of a switch head 31 with a snap switch 32 (FIG. 4), which can optionally also contain a signal contact which actuates a warning lamp before touching the hot hob, and a long rod-shaped temperature sensor 33 which extends diagonally over the entire heating unit 17 protrudes. He crosses the main heating element 27 substantially diametrically (but can also be offset from it) and cuts the corners of the two side support shell regions 22, 23 so that he still protrudes somewhat beyond the additional heating elements 27.
  • the temperature sensor 33 is arranged between the heating resistors and the glass ceramic plate and runs through U-shaped cutouts in the webs.
  • the rod-shaped temperature sensor consists, in a manner known per se, of an expansion sleeve made of quartz glass and a metallic rod with greater thermal expansion inside.
  • the circuit of the heating elements 26, 27 is shown in FIG.
  • the two additional heating elements - .. 27 are connected in series independently of the heating element 26, while the entire heating 17 can be switched off by the switch 32 of the temperature limiter 30.
  • All three heating elements can be controlled together by a power control device 36 in a known design.
  • a power control device known per se according to DE-AS 26 25 715 can be used, to which reference is made.
  • the electrical power supplied to the heating elements can be steplessly controlled independently of the hotplate temperature by manual adjustment on a setting button 37, the power being emitted in individual power pulses of different relative operating times.
  • the power control device has a snap switch 38 which is actuated by a bimetal 39 which is heated by a control heater 40 connected in parallel by the consumer.
  • the mutual position of the bimetal and the switch is adjusted by a control cam 42 actuated by the adjusting knob 37 via an adjusting shaft 41.
  • a switch 43 is mechanically positioned so that the setting shaft 41 passes through the switch 43.
  • the switch 43 shown in detail in FIGS. 5 and 6 serves to selectively switch on the main heating element 26 alone and this together with the additional heating elements 27. This is done by rotating the setting shaft 41 in one or the other direction of rotation. Since the setting shaft for the power control device can be rotated through 360 °, it is possible, for example, to turn all three heating elements together when the setting button 37 is turned clockwise, ie starting with the low power ten, while only the main heating element 26 is switched on when rotating counterclockwise (see also Fig. 7).
  • the switch 43 has on the setting shaft 41 two cam disks 44 with cams 45 facing each other but offset in the circumferential direction, between which a projection 46 of a rocker switch runs.
  • the rocker switch 47 consists of a flat sheet metal part arranged laterally or tangentially to the setting shaft 41 and is pivotally mounted at one end in a bearing 48. At the opposite free end, it has a contact bridge 49, which can work with two fixed contacts 50 to bridge them.
  • the contact bridge 49 is limitedly movable on an insulating part 51.
  • the rocker switch is fork-shaped and receives a tension spring 52 in the formation, which runs in the direction of the middle pivot position (neutral position) of the rocker switch 47.
  • One end of the tension spring 52 is on the rocker switch and the other on one attached to the switch housing 53 bracket 54 attached.
  • the projection 46 is arranged between the cams 45 such that when the power control device 36 is set from the zero position of the adjusting knob 37 (FIG. 7), the switching element 55 formed by the rocker switch 47, the tension spring 52 and the contacts 50 can be switched over . If, for example in the position shown in FIG. 6, the adjusting knob 37 is turned counterclockwise, the rocker switch is pressed from its upper position, in which it rests on the contacts 50, via the neutral central position into its lower position, shown in broken lines. So it is a switching element with two stable end positions.
  • the switch is very flat and can be used on an existing one Power control device 36 are placed so that an approximately cubic compact block is formed. It would also be possible to provide the switch on the back of the power control unit. If necessary, it could also contain further switching elements in its housing, for example a double-pole disconnection which is normally provided in the power control unit 36.
  • rocker switch 57 a switching element could also be provided which corresponds to a conventional snap switch with a spring tongue inserted.
  • the design shown here is particularly robust and takes into account the fact that a sufficient switching force is available.
  • the rocker switch could also be arranged with an axis parallel to the setting shaft, the cams being effective in the radial direction.
  • the setting range takes up almost 360 ° on the setting button 37.
  • the heating 17 or the hotplate 15 can be used very universally. If only the central main heating element 26 is switched on, it can also be used for normal cooking and roasting processes, like the other hotplates 14.
  • an elongated, rectangular hotplate is formed, which can be used for keeping food warm, which is normally on elongated serving platters, when the power supplied is low, for example when the power control device 36 is set low
  • power control device 36 in the order of magnitude of 5 to 7% of the total power, ie with a power of one thousand watts of the main heating element 27 and five hundred watts in each of the additional heating elements 27, a warming power of one hundred to one hundred and forty could be achieved Watts can be set, which meets the requirements well.
  • the hotplate 15 for frying with all the heating elements at full power, in which case this heating surface is particularly well adapted to the roasting dishes (for example oval roasters).
  • the symmetrical overall structure of the heater 17 provides not only a visually appealing solution, but also the same conditions over the entire heater, although the individual areas 21, 22, 23 are so well separated from one another in terms of heat that the side areas are cold when the middle area is switched on alone stay.
  • the temperature limiter mainly detects the main heating element 26 which is switched on in all operating cases, but also receives a certain amount of heat from the additional heating elements, so that the corresponding access is available even with an asymmetrically placed cooking vessel.
  • the arrangement is particularly advantageous in the case of radiant heating, but it would also be conceivable for contact radiators. In this case, the temperature sensor would then be arranged on the side opposite the glass ceramic plate.
  • the embodiment shown in Figures 8 and 9 differs from that of Figures 5 and 6 in that the switching element 55 a is formed by a normal snap switch which is carried by a snap-action switch carrier 63 attached to the housing 53 a and a switching spring with has a spring tongue supported on the snap switch carrier. At the free end of the switching spring, a contact 49 a is attached, which cooperates with a counter contact 50 a. This is opposed by an insulating counter-stop 61.
  • the contact 50 a and the counter-stop 61 are attached to a U-shaped bracket of a resilient lever 60 attached to the housing on one side, in the central region of which a switching pin 46 a is attached, which with the cams 45 a on the cam disks 44 a Shaft 41a cooperates in the same way as the projection 46 in the embodiment according to FIG. 6.
  • the contact 49 a is therefore in the space between the counter contact 50 a and the counter stop 61, which are movable via the lever 60.
  • the snap switch is thus actuated via the contact 49 a and the counter contact 50 a or the counter stop 61 from the lever 60.
  • the snap switch is aligned with the counter contacts so that it jumps to a stable end position.
  • a normal snap switch can be used, which snaps due to brief up or down movements of the lever 60 in one or the other end position, where the two electrical contacts 49 a, 50 a lie against each other, so that the additional heating element is switched on or as a result the insulating counterstop 61 is not given any contact.
  • a power control device 36 b is actuated by an adjusting button 37 b via an adjusting shaft 41 b.
  • the setting shaft 41 b protrudes freely rotatably through a cam sleeve 44 b, which carries a switch button 55 b, which acts on a normal leaf spring-like switching spring 55 b.
  • an electrical contact 49 b is arranged, which can come into engagement with a counter contact 50 b.
  • the cam sleeve 44 b mounted in the housing 53 b of the switch 43 b is connected in a rotationally fixed manner to an adjusting disk or an adjusting lever 62, which is flat under the adjusting button 37 b lies.
  • the switching arrangement is therefore coaxial.
  • the additional heating element is switched on independently of the setting of the energy regulator, which can therefore be a normal energy regulator with setting in only one direction of rotation.
  • the switching disk 62 By actuating the switching disk 62 between two positions, the switching cam closes the contacts 49 b, 50 b or opens them.
  • the switch positions can be fixed by a normal spring catch.
  • the additional switching element shown in section in FIG. 11 contains a housing 111 which is closed on one side by a cover 112. On the side opposite the cover, the housing 111 has a central bore 113 through which the adjusting shaft 114 of the adjusting device extends.
  • a driver 115 Arranged in the housing 111 is a driver 115, which has the shape of a disk with an extension 116 which is bent upward at approximately a right angle.

  • the cam disc 117 has a step 119 on its upper side, by means of which it is rotatably mounted in the central bore 113 of the housing 111.
  • the cam disk 117 has on its underside a slot-shaped groove 120 which extends over an angle of 270 ° around the central bore 118 and into which the shoulder 116 engages, see FIG. Fig. 12.
  • the driver 115 designed in the form of a disc has a central opening 121 which corresponds in shape to the non-circular cross-section of the setting shaft 114 and with which the driver 115 can be connected in a rotationally fixed manner to the setting shaft 114.
  • This rotationally fixed connection is achieved by plugging the switching element onto the setting shaft 114.
  • the approach 116 of the driver 115 engages in the slot 120. Since the cam disk 117 can rotate in the housing 111, but is not connected to the adjusting shaft 114 in a rotationally fixed manner, a stop of the extension 116 at the respective end of the groove 120 leads to a driving of the cam disk 117 when the adjusting shaft 114 rotates via the corresponding angular position. When the setting shaft 114 is turned backwards, the cam disk 117 initially stops until the shoulder 116 strikes the respective other end of the slot-shaped groove 120.
  • the cam disk 117 has on its right side in FIG. 12 a cam 122 which has a depression 123 in the region of its apex.
  • the housing 111 has three slot-like housing recesses 124, 125, 126, in each of which a metal piece is inserted, which after aft merges into a flat tongue 130, 131, 132.
  • the contacts 127, 128 and 129 are attached to the end of the metal pieces located inside the housing 111.
  • the housing-side end of the flat tongue 132 is bent in the form of a U, with the outside directed leg is fixed in the housing.
  • the inner leg 134 which is longer than the outer leg, carries at its end the contact 129, which is designed to switch between the contact 127 and the contact 128.
  • the inner leg 134 Approximately in the middle of the inner leg 134, the latter has a bend 135 which extends in the direction of the cam disk 117 and which has approximately the shape of a triangle, the tip pointing to the left being designed to interact with the depression 123 in the cam 122 of the cam disk 117. Due to the elasticity of the material, the U-shape ensures the preload of the movable contact 129 in the direction of the one fixed contact 127, so that the cam 122 can act directly on this leg to pivot it.
  • FIG. 13 shows the cam 122 with its recess 123 again.
  • Fig. 14 it can be seen that the groove 120 runs along a circle around the center of the central bore 118, covering an angular range of approximately 270 °.
  • FIG. 15 shows how the additional switch designed according to the invention is connected to an adjusting device. It is a temperature controller, whose capillary tube 136 is only indicated.
  • the housing 137 of the temperature controller has a tab on both sides of the setting shaft 114, with which the housing 137 is normally screwed onto the outer wall of a cooker or similar device.

  • the additional switching element is suitable for plugging on any adjustment device that has a rotatable adjustment shaft.
  • the non-rotatable connection with this adjusting shaft can be established not only by a positive connection, as described in the example, but also by other connections. It is particularly favorable to use the additional switching element in a control device for cooking appliances in which additional heating is to be switched on by first turning the adjusting knob to the right as far as it will go and then turning it back to the desired position. While in the described embodiment, a switch has been described, the additional switch can of course also be used for switching off alone or for switching on alone.
