Definitions

  • the invention relates to a temperature limiter for a glass ceramic cooking unit with an elongated outer tube and an inner rod arranged therein, optionally subdivided into partial rods with different expansion coefficients, the relative movement between them made possible by different coefficients of expansion of the outer tube and inner rod acting on at least one electrical switch.
  • a temperature sensor is already known (FR-A-2 435 796), which has an inner rod arranged in a metal tube.
  • This inner rod is formed in two parts, the much longer part made of ceramic, the shorter part made of metal. This is to ensure that the difference in length between the inner rod and outer tube is not too large.
  • the outer tube is fixed in the base of a switch housing, and the free end of the inner rod acts on one leg of a snap switch.
  • the temperature sensor is pivotally mounted relative to the base via a ball guide.
  • the signal switch is operated using the same lever that is used to operate the circuit breaker.
  • the temperature sensor acts on a point between the two switches of the lever, so that an increase in the path of the temperature sensor is used to actuate the signal switch.
  • an adjustment can only be made when the temperature limiter is attached to the heating element of the glass ceramic cooking unit.
  • the temperature sensor is fixed rigidly on the sheet metal plate, while the base can still be adjusted somewhat due to the pivoting design. Only then can an adjustment be made. It has been found that the adjustment can change during the operation of the device, since aging influences and also mechanical adjustments can occur.
  • an electric cooking appliance with an expansion element of a temperature limiter, which acts on two switching contacts, one of which is used to display a signal device and the other is used to switch off the heating (DE-C2-27 48 109).
  • a wire arranged in the tube is clamped on a leaf spring, the free end of which forms a lever is provided with an insulating body which actuates the two contacts.
  • a temperature switch for a glass ceramic cooktop (US-A-40 50 044), in which an inner rod arranged in a tube acts directly on the actuation point of a switch which is intended to switch off the power to the heating resistors.
  • a temperature limiter for a two-circuit heating of a glass ceramic cooktop is also known (GB-A-2 069 300).
  • the corresponding part of the temperature sensor of the temperature limiter is isolated. This is to protect the unit against overheating even with dual-circuit radiators.
  • the invention has for its object to provide a temperature limiter of the type mentioned, which always switches at the correct temperature in hotplates with several separately switchable heating areas without further measures.
  • the invention proposes a combination of a temperature limiter and a cooking unit with the features of claim 1 and such a combination with the features of claim 2.
  • the basic heating surface thus only acts on the part of the temperature sensor that is spatially assigned to it.
  • the additional heating surface then acts on the part of the temperature sensor that is spatially assigned to it.
  • the part of the inner rod assigned to the basic heating surface and the part of the inner rod assigned to the additional heating surface is referred to as the additional part rod.
  • a continuous outer tube may have a plurality of inner partial rods, for example in the area of the base heating surface the partial rod having a smaller expansion coefficient than the outer tube, while in the area of the switchable heating surface a partial rod with a different expansion coefficient is arranged.
  • the temperature sensor preferably runs approximately along a diameter over the hotplate, but it can also be offset somewhat to the side.
  • the coefficient of expansion of the inner rod in the active i.e. H. the area corresponding to the basic heating surface, smaller than the coefficient of expansion of the outer tube in this area.
  • a stainless steel can advantageously be used as the outer tube, while the inner rod is made of ceramic, which has a smaller expansion coefficient than the stainless steel.
  • the invention proposes that the coefficient of expansion of the additional, i.e. H. the part bar that can be connected to the heating surface is at least as large as that of the outer tube in this area.
  • the invention further proposes that the expansion coefficient of the additional partial rod in this case is greater than the expansion coefficient of the outer tube in the area of the additional heating surface.
  • the temperature sensor in its active area so that the inner rod has a larger expansion coefficient than the outer tube in the active, ie. H. the area assigned to the basic heating surface.
  • the invention proposes that the expansion coefficient of the partial rod assigned to the additional heating surface which can be switched on is at most as large as that of the outer tube in the region of the heating surface which can be switched on.
  • the coefficient of expansion of the partial rod is smaller than that of the outer tube.
  • the invention further proposes that the difference between the expansion coefficients of the base part rod and the outer tube in this area be in the range from about 2.5 to 18. 10- 6 , preferably around 1.3. 10- s lies.
  • the invention is particularly applicable to hotplates in which the switchable heating surface is arranged in a ring around the basic heating surface arranged in the middle.
  • the switch actuated by the temperature sensor must lie outside the outer ring area.
  • the temperature sensor extends over the entire hotplate area, it can also be advantageously provided that the temperature sensor extends from the outer edge of the hotplate over its center to the opposite separation point between the central heating surface and the switchable heating surface. In this case too, the measures according to the invention can be used with advantage.
  • the outer tube is at least partially in one piece with a housing of the switch acted upon by the temperature sensor.
  • the ceramic housing of the switch can have a tubular extension that extends over a switchable heating surface up to approximately the point of separation between this and the base heating surface.
  • the end of the lever acted upon by the inner rod can have an insulating button extending in the extension of the inner rod. This is a simple method to galvanically separate the two switches. Since this insulating button extends in extension of the inner rod, the signal switch is still operated directly by the inner rod without any lever ratios being interposed. The insulating button practically forms an extension of the inner rod.
  • connection parts of the signal switch are inserted through slots in the base of the base and twisted on the outside thereof, with multiple angled tabs being welded to the twisted ends, which are supported in slots or grooves on the base and end in tabs.
  • Pushing the connection parts through slots in the base has the advantage that the switch parts can be positioned exactly and that their position fi remains fixed.
  • the connection with the multiple angled tabs has the advantage that when the connecting cables are plugged in, forces do not act directly on the switch parts, so that the switch position does not change and the adjustment does not change even if the supply lines are attached and removed several times. Even if the connecting cables are pried open on the tabs, no effects are transmitted to the signal switch, since the tabs are supported on the base.
  • the inner rod consists of several partial rods, it can be achieved that for different temperature sensor lengths, as are necessary for radiators of different sizes, several inner rods do not have to be manufactured and stored, since the different sizes can be built up by assembling them from modularly dimensioned individual rods.
  • this measure has the advantage that even with slight bends in the outer tube, the inner rod cannot jam, which could lead to a slight shift in the response temperatures.
  • the inner rod can be acted upon by spring pressure. This enables the temperature sensor to respond quickly and precisely, both when the temperature rises and when the temperature drops.
  • the outer tube is made of metal and the inner rod is made of steatite. This means that the outer tube has a larger coefficient of expansion than the inner rod.
  • a protective tube preferably made of quartz glass, is pushed over the outer tube. This firstly protects the temperature sensor itself from mechanical or thermal influences, and secondly, the protective tube made of insulating material also offers electrical protection, so that under certain circumstances the distance between the temperature sensor and the windings of the heating can be reduced.
  • the protective tube can, for example, be held loosely in a cap which supports the end of the outer tube which is remote from the base and is designed to engage in a corresponding opening in a sheet metal plate of a radiator. Since the protective tube has a purely protective function, this loose mounting is possible.
  • the base is supported with two approaches engaging in slots in a sheet metal plate of the heating and, if necessary, is attached to the sheet metal plate with an additional bracket.
  • the power transmission from the lever to the circuit breaker takes place via an adjusting screw and a support element which has at least one, preferably two flat contact surfaces and between the adjusting screw and the actuation point of the Circuit breaker is resiliently arranged. So there is no direct contact between the adjusting screw and the operating point of the circuit breaker. Since the adjusting screw would act on the lever from different directions depending on the position of the lever due to its attachment to the lever, and the front end of the adjusting screw may not be completely rotationally symmetrical, different accuracies could occur with different positions of the adjusting screw.
  • the support element can advantageously be mounted on the lever itself. This can be done in a development such that the support element is a flat rivet attached to the free end of a rocker arm attached to the lever. By mounting the rocker arm on the main lever, its inherent rigidity eliminates the effects of a possible play of the adjusting screw in its thread.
  • the spring acts on the lever in the region of the adjusting screw. If the spring is a coil spring, for example, this leads to space-saving accommodation, since the adjusting screw must be accessible from the outside and there is space for an opening here.
  • the preferred embodiment also suggests that the end of the outer tube remote from the base has a second adjusting screw. This can be used to adjust the response temperature of the signal switch. This adjustment can also be done before installing the temperature limiter in the heating.
  • the temperature limiter shown in Fig. 1 contains a base 11, which is preferably made of steatite.
  • a temperature sensor 12 is attached to the base 11 and is constructed from an outer tube 13 made of metal and an inner rod 14 arranged inside the outer tube 13.
  • the outer tube 13 At its end 15 remote from the base, the outer tube 13 has a reduced diameter. With this end, the outer tube 13 is inserted through an opening of a cap 16.
  • the end 15 has an internal thread into which an adjusting screw 17 is screwed.
  • the outer tube 13 has two spaced, circumferential, approximately plate-shaped flanges 19 which engage in a corresponding annular groove 20 in the base 11. Through these flanges 19, the outer tube 13 is firmly connected to the base 11.
  • the inner rod 14 protrudes out of the outer tube 13 into the interior 21 of the base 11.
  • the inner end 22 of the inner rod 14 rests on a lever 23, the right bent end 24 of which is fixed in a recess 25 in the base 11.
  • the fixed end 24 forms the pivot point about which the lever 23 is pivotable.
  • the lever 23 has a hole in the extension of the inner rod 14, which is not visible in the figure, through which an insulating button 27 is inserted, which has a widened head on the side facing the inner rod 14 and is fixed to the lever 23 is connected.
  • the insulating button 27 executes an approximately linear movement in the direction of the inner rod 14. Its upper end acts on the actuation point 28 of the signal switch 29 designed as a snap switch.
  • the signal switch 29 is shown in the switched-off state, which means that the signal display is not yet switched on.
  • the snap switch of conventional construction is fixed in slot-like recesses 30, 31 in the steatite base 11.
  • the second contact 32 which has a tip, is fixed in a further slot-like recess 33.
  • the lever 23 is acted on the right by the snap switch 29 by a coil spring 34 downward in FIG. 1, so that the spring 34 acts on the inner rod 14 in FIG. 1 downward via the lever 23.
  • the outer tube 13 which is made of metal, expands more than the inner rod 14, so that the inner end 22 of the inner rod 14 slowly migrates downward when heated, so that at a certain displacement, which corresponds to the reaching of a certain temperature , the signal switch 29 snaps and establishes a conductive connection with the contact 32. This closes a circuit by arranging a signaling device, for example an incandescent lamp.
  • the steatite base 11 has a further switch 35, which is designed as a snap switch and is used to switch the electrical heating of an associated glass ceramic cooking unit.
  • the snap switch in turn has the usual design and is fixed in slot-like recesses.
  • the connections 36 are led out laterally from the base 11.
  • the lever 23 has a threaded hole in which an adjusting screw 37 is screwed.
  • the longitudinal direction of the adjusting screw 37 passes approximately through the actuation point 38 of the circuit breaker 35.
  • a rocker arm 39 consisting of thin sheet metal is attached, for example welded, to the lever 23.
  • the free end of the rocker arm 39 is provided with a flat rivet 40 which lies between the adjusting screw 37 and the actuation point 38 of the circuit breaker 35.
  • the flat rivet 40 has a smooth and flat underside directed towards the actuation point 38 and a likewise smooth and flat upper side directed towards the adjusting screw 37.
  • the flat rivet 40 can be removed more or less from the lever 23.
  • the adjusting screw 37 does not act directly, but the flat rivet 40 with its smooth, flat underside acts on the actuation point 38 of the circuit breaker 35. This enables a very precise adjustment at the response temperature of the circuit breaker 35.
  • an opening 41 is provided in the base 11, through which the adjusting screw 37 is accessible, for example with the aid of a screwdriver.
  • the opening 41 has a circumferential shoulder 42 on which the upper end of the coil spring 34 is supported.
  • the lever 23 has three cam-like projections 43 on its upper side, of which only two can be seen in the figure.
  • the signal switch 29 When the temperature sensor 12 is heated and the outer tube 13, which is preferably made of stainless steel, expands, the signal switch 29 is initially closed, which takes place at a temperature of approximately 50-60 ° C. Subsequently, the circuit breaker 35 is opened at a substantially higher temperature, which is approximately a power of ten, so that the power supply to the electrical heating is interrupted. Both are done with the help of the same temperature sensor, and due to the special design, an exact adjustment of both temperatures is possible.
  • the base 11 has on its side 44 facing the radiator two truncated pyramid-shaped projections 45 which engage in corresponding slots in a sheet metal plate of the radiator of the glass ceramic cooking unit and thereby produce a lateral and angular centering of the base 11.
  • a bracket 46 is provided which has a hole 47 and a non-visible hole corresponding to the hole 49 in the base 11 and the slots 50 (FIG. 2) corresponding recesses for the screw or rivet fastening having.
  • the base 11 additionally has a hole 48, to which a cover can be riveted. This riveting to a hole is sufficient.
  • Fig. 2 shows the base 11 with the switches 29 and 35 arranged therein without the temperature sensor 12. It can be seen that the annular grooves 20 for the flanges 19 of the outer tube 13 have slots 50 in the base of the base 11, through which on the outer edges of the Flanges 19 attached metal parts can be inserted, which are then rotated on the underside of the base shown in Fig. 3, whereby an exact and play-free fixing of the outer tube 13 is achieved. By arranging two such flanges 19, annular grooves 20 and slots 50, this attachment is reinforced. Since the bracket 46 also has recesses corresponding to the slots 50, the bracket 46 can also be securely fixed at the same time with the aid of the metal tabs to be rotated.
  • Fig. 2 shows the lever 23 in a position which it normally cannot take without the inner rod 14. This option was chosen for reasons of improved presentation.
  • the inner rod 14 consists of several partial rods 14a, 14b, of which only two are shown in FIG. 1. In FIG. 5, which will be dealt with later, three partial bars are shown. Of course, a larger number of bars are also possible.
  • the provision of a plurality of partial bars has the advantage that, on the one hand, storage is simplified if the inner bars are constructed from a plurality of identical sized partial bars. On the other hand, if the outer tube is slightly bent, the inner rod cannot become jammed, which would be possible with a one-piece inner rod. On the other hand, the construction of several partial bars makes it possible to use partial bars made of different materials and with different coefficients of expansion.
  • a protective tube 51 made of quartz glass is pushed over the outer tube 13 of the temperature sensor 12, the end 52 remote from the base engages with play in the cap 16 already mentioned.
  • the cap 16 has a circumferential, outwardly directed edge 53, so that it can be inserted into an opening in a metal plate without the possibility of being lost.
  • the slots 50 for fixing the base end of the outer tube 13 can be seen as well as the connecting parts 54 of the signal switch 29. They are also inserted through slots 55 in the bottom 56 of the base 11 and then rotated so that the switch parts are precisely defined.
  • the bottom 56 in the area of the connecting parts 54 has further notches 57 and 58, of which the notches 57 run approximately parallel but offset to the slots 55, while the notches 58 run parallel to the twisted connecting parts 54 of the signal switch 29.
  • the dashed line 59 in FIG. 3 indicates the geometrical relationship in which the notches 57 and 58 with respect to the connecting part 54 run.
  • a tab 60 see FIG. 4, is welded to the switch part 54 and runs along the line 59.
  • the tab 60 like the line 59, is bent twice in the longitudinal direction, so that its two ends 61, 62 are bent relative to the straight central part. In the rectilinear central part, the tab 60 is welded to the connecting part 54, which is only indicated in FIG. 4.
  • the tab 60 has on its underside two lugs 63, 64, of which the lug 63 engages in the notch 57 and the lug 64 in the notch 58.
  • One end 61 of the tab 60 has a first tab 65, while the other end 62 has a second tab 66 directed downwards at right angles. Both flat tabs preferably have different dimensions so that different plug devices can be used.
  • FIG. 5 schematically shows the arrangement of the temperature sensor 12 in a glass ceramic cooking unit, in which the cooking unit has a shaped body 70 for receiving the heaters.
  • the molded body 70 has a flat bottom 71 and a circumferential flat-cylindrical flange 72 with openings 73 for receiving the temperature sensor 12.
  • the sheet metal plate which is provided per se, to which the arrangement of temperature sensor 12 and switch base 11 is fastened, is not shown for reasons of simplification.
  • Concentric to the circumferential flange 72, the molded body 70 has a circumferential rib 74 which has the same height as the flange 72.
  • the rib 74 also contains openings 75 for receiving the temperature sensor 12th
  • the electrical heaters 76, 77 are arranged on the top of the bottom 71 of the shaped body 70.
  • the glass ceramic cooking unit can either be operated only with the electric heater 76, or with the electric heaters 76 and 77. Therefore, the space within the rib 74 forms a central heating surface, while the annular space between the rib 74 and the flange 72 forms a switchable heating surface.
  • the inner rod 14 of the temperature sensor 12 according to FIG. 5 is divided into three partial rods 14a, 14b and 14c.
  • the central sub-bar 14b extends substantially over the area within the rib 74, i.e. H. it corresponds in its arrangement and dimensions to the central heating surface.
  • the other two partial rods 14a, 14c lie in the area between the rib 74 and the flange 72, i. H. their arrangement and dimensions correspond to the switchable heating surface.
  • the outer ie. H. the connecting rods 14a, 14c which can be connected to the heating surface have an expansion coefficient which is different from the expansion coefficient of the central partial rod 14b.
  • the outer tube 13 is made of the same material throughout.
  • the tube 13 is preferably made of stainless steel and the inner partial rod 14b is made of ceramic, so that it has a smaller coefficient of expansion than the outer tube 13.
  • the coefficient of expansion of the partial rods 14a and 14c is at least as large as that of the outer tube 13, but preferably larger. As a result, the influence of the switchable electrical heating 77 is practically overcompensated.
  • the outer tube 13 was in one piece in the embodiment according to FIGS. 1 and 5, in the embodiment according to FIG. 6 the outer tube 81 is only one piece in its central region; it is continued to the free end 15 of the temperature sensor by a section 85 which extends from another material, in this case ceramic.

  • the middle section 81 of the outer tube has a larger coefficient of expansion than the section 82 and the lug 85, while at the same time the partial rods 14a and 14c also have a larger coefficient of expansion than the middle part rod 14b.
  • the middle part of the outer tube can be made of the same material as the outer part rods 14a and 14c, while on the other hand the middle part rod 14b is made of ceramic as well as the section 82 and the extension 85 of the housing 83.
  • the arrangement of the embodiment according to FIG. 6 would take place in such a way that the middle part 81 of the outer tube is arranged above the middle heating surface, while the extension 85 and the section 82 would be arranged above the switchable heating surface.
  • the arrangement of the temperature sensor 12 can also be such that, starting from the arrangement according to FIG. 5, the temperature sensor 12 extends from the outer flange 72 of the molded body 70 via the rib 74 to the opposite rib 74 and ends there. In this case, the overcompensation shown would only take place in the area of the partial bar 14a.
