    Description: The invention relates to a cooking appliance with a crucible and a lid pivotable by an electric drive and by a drive movable by the drive for closing the crucible and having a control for the drive, wherein the lid has an open, a partially opened and can take a closed position and the drive and the transmission are designed so that the drive to pivot the lid from the open to the partially open position and the operator can manually transfer the lid from the partially open to the closed position. Furthermore, the invention relates to a method for operating a cooking appliance.
    Cooking appliances with a pivoting or tilting crucible are also referred to as dumpers. They are all-round appliances in which, for example, they can be heated, cooked, roasted or fried. The crucibles can be swiveled forward to the operator to empty the crucible. After the crucibles are heavy, especially when filled, this tilting is usually done by a motor. In addition, the crucibles are closed by a hinged lid, which is operated manually or by motor. The pivot axis of the lid is provided away from the crucible on the frame of the cooking appliance and is usually in the region of the upper, the operator remote end of the crucible. A generic cooking appliance is known from DE 10 2012 020 631 A1. In this very functional cooking appliance, there is a common drive for the lid and the crucible and an intermediate gear, in which the drive is integrated. Drive and gearbox are designed so that the crucible can only be tilted with the lid open.
    Another cooking appliance is known from EP 1 369 071 A1, in which the lid has an electric drive and a gas spring formed in series therewith. The pivoting movement of the lid can be operated purely mechanically and / or purely electrically. The drive motor is movable between two end points, namely one of the open position of the lid and a position associated with the closed position of the lid.
    The operation of these known cooking appliances is very simple and is very appreciated in practice. In particular, the ability to quickly close and open the lid quickly, is due to the time pressure in kitchens high acceptance. In addition, however, the motor closing or partial closure of the lid is often used.
    Depending on the design of the cooking appliance or after setting up cooking appliances can be positioned very high in part, making it difficult for small operators manual use of the lid. Namely, the lid is in the open position and is almost perpendicular from the top of the crucible, so the handle on the lid may be difficult or impossible to be reached by the small operator. For this reason, this operator is instructed to use the motor drive.
    The object of the invention is to facilitate the operation of a cooking appliance with motorized pivot lid just for small operators.
    The object is achieved in a cooking appliance of the type mentioned above in that the partially open position is on the control of the user individually programmable, variable position.
    In the prior art, although the drive at any intermediate position and thus partially open position of the lid can be switched off, but this requires constant control by the operator who must remain permanently on the operating display during the lowering movement to the drive at the appropriate intermediate position to stop. The invention provides a different solution. Here is a predetermined, partially open position of the lid stored in the controller, but individually changeable by the operator, because it is individually reprogrammable. This means that the operator can, depending on its size, adjust the partially opened position, which is approached very frequently during the cooking operation. This, as experiments have found, greatly facilitates the operation of the cooking appliance according to the invention and creates a high level of acceptance, also to use the comfortable drive and to flexibly jump between manual drive and motor drive to optimize the personal workflow.
    An alternative optimization of the cooking appliance or an additional optimization of the cooking appliance in terms of ease of use is created by the fact that a predetermined time is stored in the controller and the controller is programmed so that after motorized method of the lid from the open or closed in the partially open position, the motor is driven to re-open the lid and returns the lid in the open position, if within the predetermined time, the lid is not pivoted to the closed position. It is therefore assumed that the user despite the lowering of the lid in the partially open position then did not want to close the lid completely, so that the lid is safely returned to the open position.
    The predetermined time can be programmed individually by the user.
    The inventive device is equipped in particular with a tilting crucible.
    The cooking appliance according to the invention provides in particular that the control causes a lowering of the lid from the open or closed in the partially open position after pressing and releasing a control button further into the partially open position. The solution provided heretofore, to have to hold the control button permanently pressed to lower the lid is changed by this solution. Thus, the operator can quickly press the corresponding button to lower and work during the phase of lowering the lid until reaching the partially open position otherwise.
    Drive and transmission can be configured and have a decoupling device which is designed so that the motor is moved to manual transfer of the lid in the closed position to its original position, which corresponds to the open position of the lid without swinging the lid , This is a protection mechanism for the drive. The drive would otherwise remain in the end position in which he has brought the lid in the partially open or closed position. However, if then the lid is then manually opened, the force would be applied directly to the motor and the user would have to work against the motor. On the one hand, if such a movement of the drive is possible at all, it is costly and, on the other hand, it would unnecessarily burden the engine and transmission. Thus, the lid remains in the closed position, but the drive moves back to its original position, so that for the manual opening of the lid, the complete pivoting is available without having to work against the drive. One option for preventing the lid from being opened during this movement of the drive is to utilize a dead center or over-center situation by manually closing the lid in the drive mechanism or drive linkage. For example, when the cover is manually closed, a decoupling device (e.g., gas spring) that couples the drive to the cover, more specifically to a lever coupled to the cover, places it in a dead or over dead center position with respect to the pivot axis of the cover. The result is that when moving the drive in the position corresponding to a motor-open lid, the drive against the at its lid-side end positionally fixed (due to dead or Übertotpunktlage) positioned pivot axis of the decoupling presses and thus the decoupling device collapses. The decoupling device may for example be a gas spring. The aforementioned repositioning of the drive and a decoupling of the movement of the drive from the lid movement is made possible by a gas pressure spring.
    But the decoupling device may also be designed so that the lid from the closed position manually and decoupled from the engine can be pivoted into the open position. In particular, the lid can be manually placed in any intermediate position.
    As previously explained, the controller may be programmed so that the lowering of the lid in the partially open position is done only with a short or several short consecutive keystrokes without a permanent key pressure during the movement is required. Conversely, the controller can be programmed in such a way that the lowering only takes place when the key is pressed continuously, so that the operator must keep the key pressed while the lowering movement takes place. The lid then stops but also in spite of further pressing in the partially open position.
    An embodiment of the invention provides that the controller is programmed so that the basic position of the lid is the partially open position. This position is thus the most frequently or most permanently used position, from which then the opening or closing movement can be done manually and promptly by the operator. For example, the lid is then opened quickly when a pot tilting is required, if cooking with cooking baskets should be done or water should run into the crucible automatically. This integrated into the cooking water inlet is namely only open when the lid is in the open position.
    The cooking appliance can also perform the following function, which is possible by appropriate programming of the control: After pivoting the lid from the open or closed to the partially open position and then manual or motorized method of the lid in the closed position, the control moves on Receiving a key signal, the lid in the open position. Alternatively, the partially opened position may be that which is approached first by pressing a key from the closed position.
    The programming of the partially opened position can be done for example by entering a swivel angle (including a placeholder function, for example, by appropriate numbers, which angles are deposited) via a keyboard. The partially open position can be selected steplessly or in predefined stages. Alternatively or additionally, a so-called teaching function is possible in which the cover is moved to the desired partially opened position and then this position is stored as a desired partially opened position by pressing a button.
    The invention further relates to a method for operating a cooking appliance according to the invention, which has a plurality of possible partially open positions, that is, a plurality of possible partially open positions are programmable. The method according to the invention provides that a partially open position of the lid is programmed and the cover is pivoted by pressing a key motor from the open to the partially open position. Of course, the term "pressing a button" does not just mean pressing or pressing a single button once. Rather, to avoid incorrect operation, it may also be provided that, for example, the simultaneous or successive actuation of several keys or the repeated actuation of a key only leads to the triggering of the corresponding movement.
    An additional supplementary or alternative method for operating a cooking appliance according to the invention provides that also several possible predetermined times can be stored in the controller, but that a time is stored in the controller as a predetermined time. The lid is then motor-pivoted by motorized movement of the lid from the open to the partially open position then back to the open position, if within the time stored in the control of the lid is not pivoted to the closed position.
    After manual transfer of the lid in the closed position of the engine, as already explained above with reference to the cooking appliance, automatically be returned to the starting position without swinging the lid. This starting position corresponds to the position of the drive in the open position of the lid.
    As also explained above, the resetting of the motor can be carried out in its initial position by interposing a decoupling device, since during this movement, the lid should not be pivoted.
    E in lowering the lid in the partially open position is preferably carried out only by a permanent key press, but alternatively by a triggering key press, so that the key is then no longer actuated and the drive continues to proceed to the partially open position of the lid.
    A further development of the inventive method further provides that after pivoting the lid from the open to the partially open position and then manual or motorized method of the lid in the closed position, the control pivots on receiving a key signal, the lid in the open position.
    As already explained in connection with the cooking appliance according to the invention, the partially opened position is programmed by entering a swivel angle via a keyboard and / or by moving the lid in the desired partially open position and storing the position.
    The cooking appliance according to the invention and the method according to the invention provide in particular for the use of a single drive for pivoting the crucible as well as for pivoting the lid.

    In Fig. 1, a cooking appliance is shown, with a crucible 10 which is tilted forward about a driven pan pivot axis 12 to the food or, more generally, tipping out the good located in the crucible from the crucible. The crucible pivot axis 12 is mounted on a frame, not shown, wherein the pivot axis 12 is rotatably coupled to the crucible 10, so that a rotation of the crucible pivot axis 12 leads to a tilting of the crucible 10.
    The crucible 10 can be closed by means of a lid 14, wherein the lid 14 can be pivoted by a rotatable lid pivot axis 16. With a solid line, the lid is partially shown in the closed position, with dash-dotted line in the fully swung-up position.
    Also, the lid pivot axis 16 is mounted on the frame of the cooking appliance and is rotatably connected to the lid 14.
    For pivoting the crucible 10 and the lid 14 is a common drive 18, provided here in the form of a linear drive.
    In the embodiment shown, the linear drive is an electric lifting cylinder.
    The drive 18 has at its lid-side end a bearing 20 which is formed by a pivot axis defining extension, which is received in a guide in the form of a slot 22.
    The slot 22 is formed for example in a housing-side bracket 24, which is not to be understood as limiting. The bearing block 24 is shown in broken lines.
    The bearing 20, more specifically the extension is coupled to a fixed part of the drive 18 forming the storage part 26. The bearing member 26 may be extendable, in the present case, however, the bearing member 26 is a non-extendable end of the drive 18 in the form of a clevis, whereas at the opposite end of the drive 18 an extendable rod 28 is formed, in turn, at its free end a bearing, namely a crucible-side bearing 30 forms or carries.
    The crucible-side bearing 30 is a pivot axis, with which the rod 28 is coupled to a pivot lever 32. The pivot lever 32 is in turn rotatably coupled to the crucible pivot axis 12.
    The bearing 20 at the opposite end of the linear drive 18 in turn is coupled to a power transmission member 34, which may be, for example, a rod or, as in the present case, a gas spring. The power transmission member 34 is coupled at its opposite end via a bearing 36 with a pivot lever 38 which is rotatably coupled to the lid pivot axis 16.
    The construction shown with the pivot levers 32, 38, the power transmission part 34 and the individual bearings 20, 30, 36 and the drive 18 forms a transmission in the form of a linkage, in which the drive 18 is integrated and forms a linkage section. The drive 18 is thus in the direct power flow path between the crucible pivot axis 12 and the lid pivot axis 16 and is connected, so to speak, in series with the other parts of the linkage.
    The bearings 20, 30 for the drive 18 are both moved by the linear drive 18, so that a kind of floating or flying support for the drive 18 results.
    There are several stops provided to ensure that only ever a bearing 20 or 30 is moved by the switched-linear actuator 18. These stops form a device for restricting the degree of freedom of at least one of the bearings 20 or 30.
    A first stop 40 is formed by the cover associated axial end of the edge of the slot 22.
    A second stop 42 is defined by the opposite edge, that is, the opposite axial end of the slot 22.
    A third stop 44 is formed by the support of the crucible in the cooking position on the frame.
    In the illustrated embodiment are exclusively rigid, that is not switchable and immovable attacks exist.
    The provided on the cover-side axial end of the linear drive first stop 40 is provided for limiting the lid pivoting movement, as will be explained below.
    In the starting position, in which the crucible 10 is in the cooking position and thus on the third, i. the crucible stop 44 rests, that is horizontally aligned and the lid 14 closes the crucible 10, the bearings 20, 30 in position A, that is maximum close together. Here, the bearing 20, more precisely the corresponding drive-side extension, which protrudes into the slot 22, abut against the stop 42.
    If the drive 18 is turned on, the rod 28 continues to extend. However, the lever mimic is so formed, and the crucible 10 is so heavy in relation to the cover 14 that the bearing 30 remains in the position A, whereas the bearing 20 moves along the guide 22 to the right, so that the power transmission part 34 moved to the right is while the pivot lever 38 in the clockwise direction and thus the lid 14 swings open.
    The opening movement for the cover 14 is then stopped when the first stop 40 from the bearing 20 and the drive-side extension, which forms the bearing is reached (position B). In this position, as well as in any other intermediate position, the drive 18 can be stopped. If the crucible 10 is then to be pivoted, the drive 18 continues to be operated in the same direction, the rod 28 still extends further and pivots the pivoting lever 32 by moving the bearing 30 into the position B. The crucible 10 is thereby tilted.
    Optionally, a further mechanical stop may be provided, which is positioned, for example, in the pivoting direction in front of the pivot lever 32 and against which the pivot lever 32 in the position B presses. When tilted crucible 10 and pivoted lid 14, the bearings 20, 30 are each in the position B.
    The pivot angle of the crucible 10 is greater than or equal to 60 °, where it can be stopped in any intermediate position.
    It is important, however, that at each position of the crucible 10, and the maximum position, the focus of the crucible 10 is always behind the crucible pivot axis 12, ie between the pivot axes 12, 16, so there is no force reversal from pressure to tensile load for the drive comes.
    The travel for the bearing 20 is the stroke xd, so the travel for the lid. The stroke of the bearing 30, which is designated by xt in Fig. 1, is the travel for the crucible 10th
    When pivoting back of crucible 10 and lid 14 pivots due to the gravity of the crucible 10 of this first back, with the drive 18 is supported on the stop 40 and the rod 28 is still loaded on pressure.
    If the crucible 10 has reached its horizontal position and the crucible lies on the crucible stop 44, the bearing 30 is again in position A. If the linear drive 18 is actuated further in the same direction, then the cover 14 is pivoted back by the bearing 20 is moved in the guide 22 back to position A. Again, the gravity of the lid cause this closing movement, so that the drive 18 acts as a brake. Of course, depending on the geometry, it is also possible for a pull to be exerted to close the lid 14.
    The cover 14 is movable by means of the drive 18 between three positions, which are shown differently in Fig. 1. The closed position of the lid 14 is shown by solid lines. Here, the lid 14 closes the crucible 10. A partially open position is shown with broken lines and a fully open position with dotted lines.
    The drive 18 is coupled to a controller 45 and the controller 45 is in turn coupled to a control panel, for example a touchscreen. Using control buttons on the control panel, the controller 45 can also be programmed individually. This allows the operator to individually program and change the partially opened position so that the lid handle is always easily accessible in the partially opened position. The partially open position is either any position between the open and closed positions or can be individually selected stepwise in an angular field.
    The programming of the operator of the desired partially open position of the lid 14 takes place, for example, by entering a swivel angle via a keyboard and / or by so-called teaching. In this case, the cover 14 is brought by motor into the desired partially open position, so that the controller 45 also knows this position. By pressing a button, this position is stored in the controller 45.
    If the operator wants to move the lid from the open or closed to the partially opened position, then, for example, pressing a button on the control panel is sufficient. The drive 18 then moves the lid 14 without stopping in the individual partially open position.
    About the gas spring, which represents a decoupling device for the manual and the motor drive, it is possible that the operator of the cooking device, the cover 14 manually opens partially or completely or closes. The stroke xd is then used to make a small angular movement of the lid, for example, to immerse the lid in an attached basket food in a cooking medium (oil, water, ...) and dig it out again.
    The operator can thus completely close the lid 14 from any position, but at least from the partially open and the open position.
    If the cover 14 is thus moved in the partially open position, it can be closed manually from this position, i. E. be brought into the closed position.
    When the lid 14 is pivoted from the open position by motor to the partially open position and then manually to the closed position, which takes place by partial movement of the power transmission part 34, the drive 18 initiates initiated by the controller 45 back to its original position which corresponds to its position associated with an open position of the lid 14. In the embodiment of FIG. 1, this is the position in which the bearing 20 is maximally to the right, that is, in position B. In the partially open position of the lid, the bearing 20 was located between positions A and B. During this movement of the drive 18, the lid 14 is not swung open, because a dead center or Übertotpunktsituation is exploited by the manual closure of the lid in the drive mechanism or drive linkage. The gas spring 34 is brought to the manual closure of the lid in a dead or Übertotpunktlage the pivot axis of the lid. That is, the pivot axis of the bearing 36 is located on or below the connecting line T of the centers of the pivot axis 16 and the bearing 20 (see Fig. 1). In the intermediate position, in which the bearing 20 extends during manual closure, the bearing 20 is located between the end points in the guide 22. The bearing 20 is indicated here by broken lines. The result is that when moving the drive in the position corresponding to a motor-open lid 14, the drive 18 against the at its lid-side end positionally fixed (due to the dead or Übertotpunktlage) positioned axis 36 presses and thus compresses the gas spring. While the leverage ratios do not clearly express this in FIG. 1, because this figure is simplified primarily to illustrate the basic functions, the downwardly cranked lever 38 in FIGS. 2, and 4 to 7 shows that the center of the pivot axis 36 coincides little constructive effort can be easily moved under the connecting line T. In addition to those already mentioned above, there are other various variants which are not listed exhaustively below and which can also be combined with one another or between which steps can be combined, conceivable in order to operate the cooking appliance.
    Variant a) If the cover 14 is driven by motor from the open or closed position to the partially opened position by the push of a button, in order to be subsequently closed manually, the cover waits for a predetermined time T1 in the open position.
    This predetermined time T1 can be programmed individually by the user.
    If the lid 14 is not moved to the closed position within this time T1, be it manually or by motor, the controller 45 controls the drive 18 so that it returns the lid 14 back to the open position.
    Variation b) The lid 14 is lowered by pressing a button from the open or closed to the partially opened position, from which the operator can also reach the handle of the lid and close it manually. From the partially open position, the lid 14 can be moved completely back into the open position by pressing the or another button. But when the lid is closed, it can swing open at the push of a button either in the open position or in the partially open position. Here it is possible, for example, to work with two different keys, which stand for a partial opening or a complete opening.
    Alternatively, the controller 45 may be programmed so that either always the open or always the partially opened position is approached.
    Variant c) The lowering of the lid 14 into the partially opened position is only possible by a permanent pressing of the button. The lid 14 remains in the partially open position only then, if continue to press the button to lower the lid. For example, when the button is released, the controller 50 may either be programmed so that the lid 14, if not manually moved to the closed position, is immediately folded back to the open position, or the lid 14 remains for a time T2 in this partially opened position.
    If during this time T2 no manual closure takes place, the controller 45 controls the drive 18 again accordingly to open the lid.
    If the lid 14 is manually closed with the button pressed or within the time T2 and then opened by pressing a button, the drive 18 is switched so that it returns the lid 14 in the open position.
    Variant d) The basic position of the lid 14 is the partially opened position. From this position, the lid can be moved by motor or manually in the closed or open position.
    The embodiment according to FIG. 2 essentially corresponds to that according to FIG. 1, so that only the differences will be discussed below. The previously introduced reference numbers remain the same or equivalent parts.
    Further, the operation of the lid 14 and variable programming of the partially open position of the lid 14 is identical in all other embodiments with the features and options just explained in connection with FIG. 1 and in the introduction to the description and the claims.
    The essential difference between the embodiments according to FIGS. 1 and 2 lies in the fact that a safety interlock is provided, which is a transmission of the force during mechanical, ie manual opening and / or manual closing of the cover on the crucible pivot axis 32 prevented.
    In the embodiment of Fig. 2, the safety lock comprises the guide or slot 22, which has a particular shape. The corresponding slot 22 is namely curved at its right, that is deckelseitigem end, namely obliquely downwards. The corresponding portion of the slot is called the locking portion 50. This locking portion 50 extends transversely, substantially perpendicular to the cover-side power transmission part 34, more precisely to its line of action in the open position of the lid (see enlarged view of the slot 22 in Fig. 2a). By this curvature of the slot 22, the bearing 20, again here the extension that couples the drive 18 with the power transmission part 34, press against the edge of the slot 22 without slipping off of it. This results in a stable, self-locking position. The force exerted on the cover 14 is thus introduced directly into the bearing block 24 and not in the rest of the linkage.
    The slot 22 (safety lock) is also designed so that when reaching the bearing 20 on the stop 40 (or crucible reached stop 44), ie the change from pot movement to cover movement, only a small relative movement results on the lid. This makes it possible to realize a simple shutdown of the drive 28 after passing through the crucible stroke Xt with conventional micro or proximity switches and thus inevitable, low tracking of the drive without producing unwanted movement on the lid. In other words, the shape of the slot 22 is selected so that an inaccurate shutdown of the drive after reaching the bearing 30 in position A and crucible in cooking position on stop 44 no undesirable movement of the lid 14 results.
    With a switching element for the bearing 20 in position A (stop 40), with a suitable embodiment of the oblong hole 22 (for example, as shown in Fig. 2a) can also integrate a further safety function by means of an integrated safety device. As soon as when passing through the stroke Xt (bearing 30 from position B to position A, ie Tiegelab-lowering) an impermissible resistance results in excessive force (eg collision with the object under the crucible, crushing a hand of the operator, ...), moves the bearing 20 out of the position B (away from the stop 40), which can be achieved with a mounted at stop 40 proximity or micro-switch, which monitors the position of the bearing 20, a quick shutdown of the drive. Thus, this integrated safety device on the one hand, the mechanics of the device (linkage) from damage, as well as a violation of the operator can be prevented.
    Of course, alternatively, the linear drive can also be installed rotated by 180 °, that is, the rod 28 is provided on the cover-side end of the drive.
    Fig. 3 shows a variant of the coupling point between the linear drive 18 and power transmission part 34. Instead of a fixed coupling on the bearing 20 here a bearing 20 is provided in which over inclined planes and levers a force deflection including attacks can be achieved. For example, the drive 18 drives a part 60 with an inclined plane 62, which is movable along a guide 64. The inclined plane 62 is contacted by an inclined plane 66 of a second part 68. The part 68 is in turn mounted in a direction transverse to the guide direction of the part 60, here for example perpendicular thereto. With the part 68, the power transmission part 34 is coupled.
    If the linear drive 18 is driven and moves the part 60 to the right, the part 68 is moved by the inclined planes 62, 66 upwards and thus the power transmission part 34 is also moved upward to lift the lid 14.
    The part 60 is moved until it has reached the first stop 40. Subsequently, the opposite bearing 30 of the linear actuator 18 is moved.
    A special feature of the drive system for pivoting the crucible 10 and the lid 14 is that despite the provision of only a common drive by exclusively rigid stops when driving the drive in one direction in time, these attacks are approached so that either the lid or the crucible is pivoted and only one end of the linear drive is moved in each case.
    The drive also makes it possible to stop the lid and crucible in any position.
    The embodiment of FIGS. 4 to 9 largely corresponds to that of FIGS. 2 and 2a, but some details are different, which will be discussed in the following.
    As before, however, the already introduced reference numerals for the same parts or parts of the same function are reused, so that no longer need to be considered individually with respect to the parts, but in the following only the differences are highlighted.
    In the embodiment according to FIGS. 4 to 9, the slot 22 is designed to be open at its end close to the drive, so that the bearing 20 can be inserted from above, allowing a quicker and easier assembly and disassembly of the drive 18 provides.
    The slot 22 has various sections, the first, from the open end obliquely downwards and away from the drive section 96, and a subsequent, slightly obliquely upward in the direction of the cover pivot axis 16 facing portion 98 and a third, obliquely downwardly extending portion 100, in which also the locking portion 50 is located.
    In the position shown in Fig. 4, the crucible is not pivoted, the lid 14, however, partially opened manually, so that the gas spring 34 is at least partially extended.
    However, the lid 14 can also be opened from its closed position, which is more common, by means of the drive 18. Then, the bearing 20 is moved from the starting position shown in Fig. 4, based on Fig. 4 to the right along the obliquely upwardly extending ramp-shaped portion 98 until the bearing 20 enters the portion 100 of the slot 22, which again obliquely downward drops and in which the bearing 20 is shown for example in Fig. 6. In this position, the lid 14 is then opened slightly, for example 20 ° to 30 °. The remaining opening movement is then manually or by means of the gas spring 34 to the fully open state, which can be seen in Fig. 6. In this state, the gas spring is in the maximum extended state. During the subsequent further actuation of the linear drive 18, the crucible 10 is then pivoted exclusively by the linear drive 18 until the state shown in FIG. 7 is reached.
    The pivoting back of the crucible 10 is then again by the drive 18. The lid 14 remains completely open.
    If the lid 14 is subsequently closed again, then the bearing 20 only has to be removed from the self-locking locking position, which occupies the bearing 20 in the state shown in FIGS. 6 and 7. For this purpose, the drive 18 is moved further, and the rod 28 continues to drive. Thus, the bearing 20 moves down from the bent down portion 100 of the slot 22 and along the obliquely downward ramp surface (section 98) downwards, as shown in Fig. 5.
    If then the position of Fig. 4 is reached again, the lid 14 can be manually pivoted completely downwards. The bearing 20 is stable in this position in a renewed self-locking position, and the force applied by the gas spring 34 on the bearing 20 by lowering the lid 14 by hand force does not go so far that the bearing 20 up into the obliquely upward-running section 96 of the slot 22 passes.
    The section 100 of the slot 22 which is closest to the lid pivot axis 16 is shown enlarged in FIG. It should be noted that, for better illustration, the oblong hole 22 is exaggerated in the area of the section 100 so that an excessively large distance of the edge 102, which delimits the section 100, from the bearing 20 results. Of course, the bearing 20 is always on the edge 102, which limits the slot 22, and is not spaced from both opposite edge portions, as shown in Fig. 8 for better representation of the edge contour.
    The portion 100 has between the points P2 and P3, the locking portion 50 which extends linearly, is extremely short and in which the edge 102, against which the bearing 20, at least perpendicular to the direction of the force F passes through the Weight of the lid 14 is applied via the gas spring 34 on the edge 102. This force is the supporting force, in which it is important that no slipping out of the bearing 100 from the section 100 occurs due to the supporting force and the orientation of the edge 102 in the region of the locking section 50.
    The edge 102 may also be inclined in the locking portion 50 so that the bearing 20 moves toward the point P2 when it rests with pressure on the edge 102.
    Immediately or approximately directly to the locking portion 50 adjoins a so-called trailing section 104. The edge 102, on which the bearing 20 rests here, forms a circular arc portion whose center lies on the imaginary central axis of the lid pivot axis 16.
    That is, when the bearing 20 slides on the edge 102 between the points P1 and P2, the opening angle of the lid 14 does not change.
    With Z the trailing distance is designated, which can pass through the bearing 20 maximum after the lid 14 is in its maximum open position.
    This open position 14 is detected by means of a sensor 104, which may also be designed as a switch. This switch or sensor 104 is coupled via a cable 108 to the control unit of the cooking appliance.
    The switch or sensor 104 may be, for example, a proximity switch, a reed or Hall contact or a microswitch or the like.
    Until the switching movement or the response of the sensor 104 has taken place and until it comes finally to shutdown of the drive 18 and its actual standstill, possibly pass a few milliseconds, which lead to a caster, which is also in a movement of the bearing 20 reflected.
    So that this caster leads to no or no noteworthy further pivotal movement of the lid 14, the caster portion 104 is provided.
    An additional or optional variant provides that an electrical braking device 110, which may be part of the controller, is present. This electric braking device 110 for braking the drive 18 is actuated from reaching the fully open position of the lid 14. As soon as the switch or sensor 106 detects the reaching of this predetermined position, a counter-current or a short-circuit for the drive 18 is generated or switched by an electronic brake circuit, which leads to a fast, abrupt and significantly shortened overrun.
    It should be emphasized that in the fully open position of the lid 14, which is shown in Fig. 6, the self-locking of the system shown in Figs. 2a and 8, by means of which the lid 14 can remain securely in the open position and by which a manual closure of the lid 14 is possible, is not limited to the embodiment with the shown special rods. There are also other guides for the bearing 20 possible, for example by a rack and a pinion or the like, so that this self-locking principle is not limited to the illustrated embodiments or the illustrated transmission or linkage.
    The aforementioned self-locking principle should also be realized at the opposite end of the slot 22, in section 96, so that the position of the bearing 20 in the position shown in Fig. 4 is stable. Here, no wobbling should be possible by slight possible displacements of the bearing 20, because this would give a poor quality impression, namely, the lid would have game, and there could be noises.
    To achieve a higher value of the cooking appliance also contributes to a damping device 114, which is shown in Fig. 9.
    The damping device 114 is for example so below the bearing 20 in the region of the portion 100 of the slot 22 that the bearing 20 or a portion connected to it, for example, a bearing eye, on the damping device 114 when the bearing 20 in the section 100 slides down. Namely, in section 100, the bearing 20 may "fall down". The damping device 14, which may be a mechanical, hydraulic or pneumatic machine element, alleviates this abrupt drop in the bearing 20.
