Definitions

  • the present invention relates to a cooking appliance, in particular a high-level cooking appliance, comprising at least a muffle which delimits a cooking compartment and has a muffle opening, a door for closing the muffle opening, a drive device which is controlled by a control circuit and is for causing the door to travel, and a pinching protection device for detecting a pinching instance.
  • DE 102 28 140 A1 discloses a high-level cooking appliance in which any pinching of objects at the base door can be detected by a plurality of pinching protection switches between the base door and the muffle compartment, wherein said pinching protection switches can be actuated independently of one another. In this case it is additionally possible to analyze a pressure increase in a door seal having a hollow profile.
  • DE 101 64 239 A1 describes a pinching protection which is triggered by different tensile forces at the traction cables which drive the base door.
  • a torque sensor is also described which measures a load torque exerted on the drive shaft of the electric motor.
  • Tensile force sensors, piezoelectric sensors and deformation or stress/strain sensors are also listed as sensors.
  • DE 102 28 141 A1 describes an optoelectronic sensor for detecting a pinching instance, wherein said sensor switches according to the quantity of reflected light.
  • Countermeasures such as stopping or reversing the door are introduced upon detection of the pinching instance. There is typically a perceptible time period which elapses between the detection of the pinching instance and the coming into effect of the countermeasures due to the inertia of the system; thus, for example, the motor must be stopped and restarted for the purpose of reversing.
  • the present invention therefore addresses the problem of providing improved operational safety for the pinching instance on a cooking appliance of the type described above.
  • the present problem is solved by the cooking appliance having the features recited in claim 1 and a method in accordance with claim 17 .
  • the cooking appliance which is in particular a high-level cooking appliance but can also be a cooking appliance having a baking carriage, is configured in such a way that, after a pinching instance has been detected by the pinching protection device, the control circuit regulates the drive device such that a force which is applied to the door does not exceed a specific force/time profile.
  • the pinching protection is preferably not embodied as a discrete assembly, but is functionally integrated in the control circuit or its module(s), which typically already includes a microcontroller.
  • a first force/time profile is provided for a pinching instance in the closing direction of the door, i.e. as a result of upward travel in the case of a high-level cooking appliance.
  • An object is typically pinched between base door and muffle frame or housing in this case.
  • a second force/time profile can be provided for a pinching instance in the opening direction of the door, if an object is then typically pinched between base door and work surface in the case of a high-level cooking appliance.
  • the third section can also be reduced further to 0 N after a certain time.
  • the third section can also be reduced further to 0 N after a certain time.
  • the pinching instance can be detected by monitoring a travel speed of the door, e.g. on the basis of percental or absolute deviation from a reference speed value or on the basis of a high positive or negative acceleration.
  • the travel movement of the door generally can be regulated depending on speed, and thus independently of a load or frictional conditions.
  • the travel direction of the door is reversed in the pinching instance, in particular if a pinching protection can only be activated when a reference speed of the door has been reached. It is also advantageous if the force/time profile can only be activated if a reference speed of the door has been reached.
  • At least one stop switch which is arranged in the region between muffle opening and door, wherein an actuation of the at least one stop switch deactivates the pinching protection device. It is then advantageous if the at least one stop switch can be actuated within an opening distance of 4 mm between muffle frame and base door. In the event that the at least one stop switch is actuated, it is then advantageous if the door can be pushed onto the muffle opening using a defined force.
  • the invention is suitable for high-level cooking appliances in which the muffle opening is a base-side muffle opening and the door is a base door which preferably moves in a linear manner.
  • FIG. 1 shows a perspective view of a high-level cooking appliance which is mounted on a wall and has a lowered base door;
  • FIG. 2 shows a perspective view of the high-level cooking appliance with closed base door
  • FIG. 3 shows a perspective view of a housing of the high-level cooking appliance without the base door
  • FIG. 4 shows a schematic side view, in cross section along the line I-I from FIG. 1 , of the high-level cooking appliance which is mounted on a wall and has a lowered base door;
  • FIG. 5 shows a front view of a further embodiment of a high-level cooking appliance
  • FIG. 6 to 11 show diagrams of travel movements of a base door in the context of various limiting conditions
  • FIGS. 12 and 13 show force/time profile curves for a base door.
  • FIG. 1 shows a high-level cooking appliance with a housing 1 .
  • the rear side of the housing 1 is mounted on a wall 2 in the manner of a suspended cabinet.
  • a cooking compartment 3 which can be monitored via a viewing window 4 installed in the front side of the housing 1 , is defined in the housing 1 .
  • the cooking compartment 3 is delimited by a muffle 5 which is equipped with a heat-insulating jacket (not shown) and that the muffle 5 has a base-side muffle opening 6 .
  • the muffle opening 6 can be closed by means of a base door 7 .
  • the base door 7 is shown lowered in FIG. 1 , wherein its underside is in contact with a work surface 8 of a kitchen entity.
  • the base door 7 In order to close the cooking compartment 3 , the base door 7 must be repositioned to the position shown in FIG. 2 , the so-called “zero position”.
  • the high-level cooking appliance has a drive device 9 , 10 .
  • the drive device 9 , 10 has a drive motor 9 which is illustrated by means of broken lines in FIGS. 1 , 2 and 4 and is arranged between the muffle 5 and an external wall of the housing 1 .
  • the drive motor 9 is arranged in the region of the rear side of the housing 1 and, as shown in FIG. 1 or 4 , has an active connection to a pair of lifting elements 10 which are connected to the base door 7 . In this case, as shown in the schematic side view in FIG.
  • each lifting element 10 is designed in the form of an L-shaped carrier whose vertical limb extends from the drive motor 9 in the housing.
  • the drive motor 9 can be actuated with the aid of an operating panel 12 , which is arranged on the front of the base door 7 in accordance with FIGS. 1 and 2 , and a control circuit 13 .
  • the control circuit 13 is located behind the operating panel 12 within the base door 7 .
  • the control circuit 13 which is composed of a plurality of spatially and functionally separate printed circuit boards that communicate via a communication bus, represents a central control unit for the appliance operation and controls and/or adjusts e.g. heating, travel of the base door 3 , conversion of user inputs, lighting, pinching protection, timing of heating elements 16 , 17 , 18 , 22 and much more.
  • a top side of the base door 7 has a cooking matrix 15 .
  • the heating elements 16 , 17 are two separate cooking position heating elements of different sizes, while the heating element 18 is a surface heating element which is provided between the two cooking position heating elements 16 , 17 and almost surrounds the cooking position heating elements 16 , 17 .
  • the cooking position heating elements 16 , 17 define associated cooking zones or cooking rings for the user; the cooking position heating elements 16 , 17 and the surface heating element 18 together define an underside-heating zone.
  • the zones can be indicated by means of a suitable motif on the surface.
  • the heating elements 16 , 17 , 18 can be controlled in each case via the control circuit 13 .
  • the heating elements 16 , 17 , 18 are embodied as radiant heating elements which are covered by a glass ceramic plate 19 .
  • the glass ceramic plate 19 has approximately the dimensions of the top of the base door 7 .
  • the glass ceramic plate 19 is also equipped with mounting openings (not shown), through which sockets project for the purpose of holding support parts 20 for cooking item carriers 21 , as is also shown in FIG. 4 .
  • a glass ceramic plate 19 it is also possible to use other—preferably quick-reacting—covers, e.g. thin sheet metal.
  • the high-level cooking appliance can be switched to a cooking position operating mode or an underside-heating operating mode, wherein these are explained below.
  • the cooking position heating elements 16 , 17 can be controlled individually via the control circuit 13 by means of operating elements 11 which are provided in the operating panel 12 , while the surface heating element 18 remains unused.
  • the cooking position operating mode can be implemented when the base door 7 is lowered as shown in FIG. 1 . However, it can also be operated in an energy-saving function when the cooking compartment 3 is closed and the base door 7 is raised.
  • control device 13 controls not only the cooking position heating elements 16 , 17 but also the surface heating element 18 .
  • the cooking matrix 15 which provides the underside heating exhibits an even distribution of the heat power output over the surface of the cooking matrix 15 , even though the heating elements 16 , 17 , 18 have different nominal powers. Therefore the heating elements 16 , 17 , 18 are preferably not switched to a continuous operation by the control circuit 13 , but the current supply to the heating elements 16 , 17 , 18 is timed. In this case, the different nominal heating powers of the heating elements 16 , 17 , 18 are reduced individually in such a way that the heating elements 16 , 17 , 18 provide an equal distribution of the heating power output over the surface of the cooking matrix 15 .
  • FIG. 4 schematically shows the position of a fan 23 , e.g. for the generation of recirculating air in the case of hot air operation or for supplying fresh air.
  • a topside-heating element 22 which is attached at a top side of the muffle 5 and can be embodied as a single circuit or multiple circuit, e.g. having an inner circuit and an outer circuit. It is also possible—not shown here for the sake of greater clarity—to provide for further heating elements such as a ring heating element between a rear wall of the housing 1 and the muffle.
  • the different operating modes including e.g.
  • topside-heating operation, hot-air operation or rapid-heating operation can be set by the control circuit 13 by switching on and setting the heating power of the heating elements 16 , 17 , 18 , 22 correspondingly, optionally with activation of the fan 23 .
  • the setting of the heating power can be done by means of suitable timing.
  • the cooking matrix 15 can be embodied differently, e.g. with or without a grilling zone, as a simple heat-retention zone (featuring a single circuit or multiple circuits) without cooking rings, etc.
  • the housing 1 has a seal 24 which faces the base door 7 .
  • the operating panel 12 is normally arranged on the front side of the base door 7 .
  • other arrangements are also conceivable, e.g. on the front side of the housing 1 , divided over various partial panels and/or partly on side surfaces of the cooking appliance. Further configurations are possible.
  • the operating elements 11 are not restricted in terms of their construction, and can comprise e.g. operating knobs, tumbler switches, pushbuttons and plastic membrane buttons.
  • the display elements 14 comprise e.g. LED, LCD and/or touchscreen displays.
  • FIG. 5 schematically shows a high-level cooking appliance from the front (not to scale), wherein the base door 7 is open and is in contact with the work surface 8 .
  • the closed state is drawn by means of a broken line.
  • Each travel switch panel 25 comprises two pushbuttons, specifically an upper CLOSE pushbutton 25 a which causes a base door 7 to travel upward in a closing direction, and a lower OPEN pushbutton 25 b which causes a base door 7 to travel downward in an opening direction.
  • the base door 7 only travels upward as a result of continuous simultaneous depression of the CLOSE buttons 25 a of both travel switch panels 25 , if possible; the base door 7 also only travels downward as a result of continuous simultaneous depression of the OPEN buttons 25 b of both travel switch panels 25 , if possible (manual operation).
  • travel switch panels 26 are attached on opposite external sides of the housing 1 and have corresponding CLOSE buttons 26 a and OPEN buttons 26 b , as drawn using dotted lines.
  • the control circuit 13 which is drawn using dash-dotted lines and is located in the interior of the base door 7 behind the operating panel 12 , switches the drive motor 9 in such a way that the base door 7 begins to move gently, i.e. not abruptly by simply starting the drive motor 9 , but via a defined ramp.
  • the control circuit 13 comprises a memory unit 27 for storing at least a destination or travel position P 0 , P 1 , P 2 , PZ of the base door 7 , preferably using volatile memory modules, e.g. DRAMs. If a destination position P 0 , P 1 , P 2 , PZ is stored, following actuation of one of the buttons 25 a , 25 b or 26 a , 26 b of the travel switch panels 25 or 26 , the base door can travel independently in the selected direction until the next destination position has been reached or until one of the buttons 25 a , 25 b or 26 a , 26 b is actuated again (automatic operation).
  • a destination or travel position P 0 , P 1 , P 2 , PZ preferably using volatile memory modules, e.g. DRAMs.
  • the lowermost destination position PZ corresponds to the maximum opening
  • the (zero) position P 0 corresponds to the closed state
  • P 1 and P 2 are freely selectable intermediate positions. If the last destination position for a direction has been reached, manual operation is additionally necessary for further travel, if possible (i.e. if the last final positions do not correspond to a maximally open final state or to the closed final state). Similarly, if no destination position is stored for a direction (which would be the case e.g. for an upward movement into the closed position if only PZ is stored but not P 0 , P 1 , P 2 ), movement in this direction requires manual operation. If no destination position is stored, e.g. in the case of a new installation or following a power disconnection, no automatic operation is possible. If the base door 7 is to travel using the automatic operation, pinching protection is preferably activated.
  • Automatic operation and manual operation are not mutually exclusive: as a result of continuous actuation of the travel switch panel(s) 25 , 26 , the base door 7 also moves in manual operation if a destination position is nonetheless available in this direction.
  • a destination position P 0 , P 1 , P 2 , PZ can be any desired position of the base door 7 between and including the zero position P 0 and the maximum opening position PZ. However, the maximum stored opening position PZ does not have to be the position which is in contact with the work surface 8 .
  • Storage of the destination position P 0 , P 1 , P 2 , PZ can be carried out with the base door 7 at the desired destination position P 0 , P 1 , P 2 , PZ by means of e.g. actuating a confirmation button 28 in the operating panel 12 for several seconds (e.g. two seconds). For the sake of greater clarity, available optical and/or acoustic signal emitters which output corresponding signals following storage of a destination position are not drawn. Arriving at the desired destination position P 0 , P 1 , P 2 , PZ to be set is achieved e.g. by means of—in this exemplary embodiment—two-handed operation of the travel switch panels 25 or 26 and manual travel to this position:
  • the high-level cooking appliance can easily be adjusted to the desired operating height of a plurality of users.
  • the destination position(s) can advantageously be deleted and/or overwritten. In one embodiment, for example, only one destination position in the open state can be stored, while the zero position P 0 is detected automatically and can be reached automatically. Alternatively, the zero position P 0 must also be stored in order that it can be reached automatically.
  • the cooking item carriers 21 can easily be inserted into the support parts 20 .
  • the viewing window 4 is mounted at approximately eye level of the user or somewhat lower, e.g. by means of a template which indicates the dimensions of the cooking appliance.
  • the drive motor 9 from FIG. 1 has at least one sensor unit 31 , 32 on a motor shaft 30 , these being arranged before or after a transmission if applicable, in order to measure a travel displacement or a position and/or a speed of the base door 7 .
  • the sensor unit can comprise e.g. one or more induction sensors, Hall-effect sensors, optoelectronic sensors, SAW sensors, etc.
  • two Hall-effect (partial) elements 31 are attached to the motor shaft 30 such that they are offset by 180°—i.e. opposite each other—and a Hall-effect measurement pick-up 32 is separately attached in a fixed manner in this region of the motor shaft.
  • a Hall-effect element 31 When a Hall-effect element 31 then travels past the measurement pick-up 32 as the motor shaft 30 rotates, a measurement signal or sensor signal is generated which is closely approximate to digital. Using (not necessarily) two Hall-effect elements 31 , therefore, two signals are output with one rotation of the motor shaft 30 . By analyzing these signals relative to time, e.g. their time difference, it is possible to determine the speed vL of the base door 7 , e.g. using comparison tables or a real-time conversion in the control circuit 13 . By means of adding or subtracting the measurement signals, it is possible to determine a travel displacement or a position of the base door 7 .
  • a speed regulator can realize the speed e.g. via a PWM-controlled power semiconductor.
  • the displacement measurement is automatically reset by initializing in the zero position P 0 of the base door 7 at each start-up, in order that e.g. an erroneous sensor signal output or sensor signal pick-up is not perpetuated.
  • the drive motor 9 can be operated by actuating both travel switch panels 25 or 26 even if the main switch 29 is switched off.
  • a single switch per travel panel is also possible, e.g. a tumbler switch which has a neutral position and only switches under pressure.
  • Other forms are also possible.
  • the type and arrangement of the operating elements 28 , 29 of the operating panel 12 are likewise not restricted.
  • control circuit 13 is flexible and not restricted in this case, and can therefore comprise a plurality of boards, e.g. a display board, a control board and a lift board, which are physically separate.
  • a 4-mm opening can be detected by stop switches 33 which, when actuated, deactivate a pinching protection.
  • the high-level cooking appliance can also be embodied without a memory unit 27 , in which case no automatic operation is then possible. This can be suitable for increased operating safety, e.g. as protection against pinching.
  • the curve runs in the direction of the arrow, i.e. from right to left.
  • the arrows that are present above the curve and point downward indicate actuations of the operating panel 12 .
  • the travel movement of the base door 7 downward begins with two-handed actuation of the travel switch panels 25 , 26 or the OPEN switches 25 b or 26 b as indicated by the upper left-hand vertical arrow.
  • the ramp R 1 is linear here.
  • the drive motor 9 is not simply switched on, therefore.
  • the travel movement is also load-independent, in particular it is independent of the load of the base door 7 or changed frictional conditions of the mechanism.
  • An input variable for this can be the rotational speed of the drive motor 9 , which speed can be measured e.g. by Hall-effect sensors.
  • the control circuit 13 detects this approach and automatically brakes the base door 7 gently, i.e. using a defined ramp R 2 , to arrive at PZ. Both ramps R 1 and R 2 can have different gradients or shapes.
  • the arrival at the base plate can be detected by stop switches 33 and/or by monitoring the travel displacement.
  • the cooking compartment 3 is not opened, i.e. the base door 7 is not moved from the zero position P 0 , if an opening safety device is active, e.g. if a specific temperature is exceeded in the cooking compartment, e.g. 425° C. or 600° F., or if a child safety device is activated.
  • an opening safety device e.g. if a specific temperature is exceeded in the cooking compartment, e.g. 425° C. or 600° F., or if a child safety device is activated.
  • the base door 7 automatically begins to travel to the position P 1 as a result of briefly actuating one of the OPEN switches 25 b or 26 b , as indicated by the upper right-hand vertical arrow.
  • the base door 7 is gently started (right-hand ramp) and automatically braked (left-hand ramp).
  • two fixed reference speeds specifically 75 mm/s (broken line) and 50 mm/s (continuous line)
  • the slower speed level is preset, e.g. upon delivery. Provision can also be made for more than two speed levels or reference speeds; unrestricted setting of the reference speed(s) by the user is also conceivable.
  • Also advantageous is provision for switching between at least two speed levels of 50 mm/s and 65 mm/s, e.g. upon device initialization.
  • FIG. 8 shows a diagram (not to scale) for travel of the base door 7 from the maximum opening position PZ to the zero position P 0 , i.e. to the closed state, using the manual operation.
  • the travel movement of the base door 7 upward begins with two-handed actuation of the CLOSE switches 25 a or 26 a , as indicated by the upper left-hand vertical arrow.
  • the control circuit 13 detects an approach at the zero position P 0 and gently brakes the base door 7 at the correct time in advance. Instead of now coming to a halt via the linear ramp directly at the zero position P 0 , however, 4 mm before the zero position P 0 provision is made for switching from speed-dependent voltage to defined voltage, i.e. by supplying a corresponding voltage to the motor 9 . It is thus possible to set a maximum force development as a result of inhibiting the drive motor 9 . This voltage varies depending on the previous history of the procedure (load, frictional conditions, etc.).
  • the detection of the 4-mm opening distance is done via the displacement measurement or additionally or alternatively via the stop switches 33 . In the region from P 0 to P 0 +4 mm, it is possible to dispense with pinching protection.
  • the monitoring of the lifting speed takes place here e.g. by means of analyzing the sensor signals of the motor shaft, wherein e.g. the time between the measurement signals or impulses is analyzed. Only in a second instance is the motor current monitored, this being a somewhat slower method.
  • the force which can be generated by the motor 9 for the purpose of travel is limited, in order to prevent accidents being caused by too severe pinching (see also FIGS. 12 and 13 ).
  • the deviation from the reference speed is detected by the control circuit 13 , e.g. as a result of a speed variation or a time-relative change of the speed.
  • the base door reverses in order that the object can be removed; an e.g. acoustic warning signal is also output if applicable.
  • the base door 7 only starts again subsequently if a travel button panel 25 , 26 is actuated again accordingly.
  • the pinching protection might only be activated if the base door 7 has reached its reference speed (if a travel button 25 a , 25 b , 26 a , 26 b is triggered prior to this the base door 7 halts immediately), and secondly a plurality of sensor signals might be analyzed, e.g. averaged.
  • FIG. 11 shows the pinching instance (upper vertical arrow) during the opening travel of the base door 7 using the automatic operation to a destination position P 1 , wherein an object is pinched between the underside of the base door 7 and the work surface 8 .
  • the pinching detection can take place via two redundant stop switches which detect a reduction—in particular an uneven reduction—in the loading of the base door 7 , whereupon the drive motor 9 reverses.
  • the maximum permitted force/time profile (see FIGS. 12 and 13 ) is not exceeded in this case.
  • FIG. 12 shows a force F in N, this being the maximum force which can be applied to the base door 7 in the pinching instance when traveling in a closing direction (i.e. upward), relative to the elapsed time t in s as a first force/time profile FT 1 .
  • the maximum force threshold of 100 N can also apply for other travel situations.
  • FIG. 13 shows a force F in N, this being the maximum force which can be applied to the base door 7 in the pinching instance when traveling in an opening direction (i.e. downward), relative to the elapsed time t in s as a second force/time profile FT 2 .
  • the time intervals and force thresholds of the force/time profiles FT 1 , FT 2 can be adapted to the implementation and to further limiting conditions.
