At least one preselected mode of operation is set in the closed position of the lower door and at least one other preselected mode of operation is set in the open position of the lower door. A preselected mode of operation is thereby activated after the lower door is set in the closed or open position.

Description

The invention relates to a high-installation cooking appliance with a muffle defining a cooking chamber with a muffle opening, a bottom door with a hob at its top for closing the muffle opening, at least one operating mode for a closed position of the bottom door and at least one operating mode for an open position of the bottom door.

For example DE 100 59 652 A1 a high-installation cooking appliance is known in which in an open position, a hob function and in a closed position a furnace function can be activated. If you want to switch to a mode other than the currently active operating mode, the active operating mode must be switched off, the floor door must then be moved by the operator, and then the new operating mode must be set and activated.

The disadvantage is that the transition between modes for different positions of the bottom door is not very comfortable.

It is the object of the present invention to provide a way to easily operate the high-installation cooking appliance, which is flexible and clear.

The present object is achieved by the high-mounting cooking appliance with the features of claim 1 and by a method according to claim 12.

For this purpose, an operating mode for each other position of the bottom door can be preset, wherein after switching to the other position, the preselected mode is automatically turned on. This is conveniently done by setting a new mode during an already running mode and activating it while in use; The previously active operating mode does not have to be switched off beforehand. The display of the 'new' mode can after a setting z. B. back to the current mode after a confirmation signal or a certain period of time back; then an indication of a set 'new' mode is useful, for example, a flashing of the mode symbol. After the end position has been reached, the device automatically switches to the new operating mode. "Transition between" means here that can be switched from the open to the closed state, or vice versa.

Advantageously, the transition between a warming function for the closed position and a warming function for the open position is provided. Then the warming function for the open state works favorably so that the hob emits a uniformly distributed and possibly constant heat output. Alternatively, the warming function can only heat one or more cooking zones. As a typical example, the application is provided, in which the user first in the open state of the cooking appliance keeps an object on the hob, z. B. previously fried foods, sauces u. v. m., The user then wants to use to keep warm larger volumes or at a higher temperature, the warming function of the closed cooking chamber, the heating power can also be constant. In the transition from one to another warming function, the cooking appliance thus not only sets the operating parameters as far as possible, but also moves the bottom door independently. The holding temperatures are freely selectable, but can be provided for easier operation and temperature levels, so that switching without further temperature setting is possible.

Alternatively or additionally, a transition between a hob function for the open position and a cooking function for the closed position may be provided. As a typical example, the use case is provided here, in which the user first prepares a food in the open state, for. B. meat seared, and then want to use the closed cooking chamber or oven room to durchgaren.

The type of transitions is not limited in principle and includes z. As well as a transition from cooking and / or roasting in the open state to keep warm in the closed state.

In particular, for searing, it is advantageous if the hob contains a roasting zone and the cooking zone in the open state can be controlled by a hob function.

For ease of use, the transition includes an automatic movement of the bottom door in the other position, if a drive motor for the bottom door is present. For example, in the transition from open position (eg, to keep warm, cooking, or roast) to closed position (eg, for keeping warm or cooking) after operating the closed mode Position the floor door move automatically and then switch the cooking appliance after reaching the closed state automatically in the selected mode. Thus, the user only has to set and activate the desired mode of operation in the following, if necessary stating operating parameters such as a cooking temperature, eg. B. via a confirmation button.

To protect against overloading and increased safety, all heating elements are switched off when moving the bottom door.

For better clarity and cost-effective production, the switching is advantageously activated by operating at least one selector switch, by the at least two, advantageously all, modes are adjustable, conveniently by cyclic operation. Thus, an associated number of selector switches can be saved for a particular mode of operation. The use of such a mode selector switch is not known and the expert also not suggested.

Advantageously, together with the switching of the operating mode, a display of the corresponding operating mode is automatically switchable, z. B. from an indication of the cooking level in the open state of the bottom door to a temperature indicator for the closed state of the bottom door or the cooking chamber.

It is advantageous for protection against burns, if the transition from the at least one operating mode for the closed position to the at least one operating mode for the open position can only be activated if the temperature in the cooking chamber has not exceeded a certain temperature threshold, z. B. 425 ° C or 600 F.

1 shows a high-installation cooking appliance with a housing 1 is shown. The back of the housing 1 is mounted on a wall 2 in the manner of a hanging cabinet. In the housing 1, a cooking chamber 3 is defined, which can be controlled via a front side in the housing 1 introduced viewing window 4. In FIG. 4 it can be seen that the cooking space 3 is delimited by a muffle 5, which is provided with a heat-insulating sheath, not shown, and that the muffle 5 has a bottom-side muffle opening 6. The muffle opening 6 is closable with a bottom door 7. In Fig. 1, the bottom door 7 is shown lowered, being with its underside in contact with a worktop 8 a kitchen device. In order to close the cooking chamber 3, the bottom door 7 is in the position shown in FIG. 2, the so-called. "Zero position" to adjust. To adjust the bottom door 7, the Hoch-Einbaugargerät a drive device 9, 10 on. The drive device 9, 10 has a drive motor 9 shown in dashed lines in FIGS. 1, 2 and 4, which is arranged between the muffle 5 and an outer wall of the housing 1. The drive motor 9 is arranged in the region of the rear side of the housing 1 and is, as shown in FIGS. 1 or 4, in operative connection with a pair of lifting elements 10, which are connected to the bottom door 7. 4, each lifting element 10 is designed as an L-shaped carrier, whose vertical leg extends from the housing-side drive motor 9 To adjust the bottom door 7, the drive motor 9 can be actuated by means of a control panel 12 and a control circuit 13, which is arranged according to FIGS. 1 and 2 at the front of the bottom door 7. As shown in Fig. 4, the control circuit 13 is located behind the control panel 12 within the bottom door 7. The control circuit 13, which is composed here of several spatially and functionally separated and communicating via a communication bus circuit boards, is a central control unit for the device operation and controls and / or regulates z. B. a heating, a method of the bottom door 3, a conversion of user input, a lighting, a pinch protection, a clocking of the radiator 16, 17, 18, 22 and much more. The control circuit may also be connected to a thermal sensor (not shown) so that it blocks opening of the cooking chamber 3 when a temperature above a certain threshold is present. Also, a child safety device may be present, which - via the control circuit 13 - also blocks a method of the bottom door 3.

FIG. 1 shows that an upper side of the bottom door 7 has a hob 15. Almost the entire surface of the hob 15 is occupied by radiators 16, 17, 18, which are indicated in phantom in Fig. 1. In Fig. 1, the radiator 16, 17 are two spaced apart, different sized cooking hob, while the radiator 18 is provided between the two cooking area heaters 16,17 surface heating element, which almost encloses the cooking area heaters 16, 17. The hotplate heaters 16, 17 define for the user associated cooking zones or hobs; the hotplate heaters 16, 17 together with the surface heating element 18 define a bottom heat zone. The zones may be indicated by a suitable decoration on the surface. The radiators 16, 17, 18 are each controlled via the control circuit 13.

In the exemplary embodiment shown, the radiators 16, 17, 18 are configured as radiant heaters, which are covered by a glass ceramic plate 19. The glass ceramic plate 19 has approximately the dimensions of the top of the bottom door 7. The glass ceramic plate 19 is further equipped with mounting holes (not shown) through the base for holding support members 20 for Gargutträger 21 protrude, as shown in Fig. 4. Instead of a glass ceramic plate 19, other - preferably quick-responding - covers can be used, for. B. a thin sheet.

With the help of a control panel 12 provided in the control knob, the high-installation cooking appliance can be switched to a cooking or a bottom heat mode, which will be explained below.

In the hob mode, the cooking surface heaters 16, 17 can be controlled individually by means of control elements 11, which are provided in the control panel 12, via the control circuit 13, while the surface heating element 18 remains out of operation. The hotplate mode is executable with the bottom door 7 lowered, as shown in Fig. 1. But it can also be operated with closed cooking chamber 3 with raised floor door 7 in an energy saving function.

In the lower heat mode, not only the hotplate heaters 16, 17 but also the surface heating element 18 are activated by the control device 13.

In order to achieve the most uniform possible tanning image of the food during the bottom heat, it is crucial that the cooking surface 15 providing the bottom heat has a uniform distribution of the heat output over the surface of the hob 15, although the heating elements 16, 17, 18 have different nominal powers. Preferably, therefore, the radiators 16, 17, 18 are not switched by the control circuit 13 to a continuous operation, but the power supply to the radiators 16, 17, 18 is clocked. The different sized nominal heating powers of the radiator 16, 17, 18 are individually reduced so that the radiators 16, 17, 18 provide a uniform over the surface of the hob 15 distribution of the heat output.

Fig. 4 shows schematically the position of a fan 23, z. B. for generating circulating air in a hot air operation or for supplying fresh air. In addition, a mounted on an upper side of the muffle 5 Oberhitzeheizkörper 22 is provided, the single-circuit or mehrkreisig, z. B. with an inner and an outer circle, can be executed. Also can - not shown here for clarity - another radiator such as a ring heater between the rear wall of the housing 1 and the muffle be present. By the control circuit 13, the various operating modes, such as, for example, top heat, hot air or Schnellaufheizbetrieb, by an appropriate activation and adjustment of the heating power of the radiator 16, 17, 18, 22, possibly with activation of the fan 23, are set. The adjustment of the heating power can be done by appropriate timing. In addition, the hob 15 can also be designed differently, for. B. with or without roasting zone, as a pure - one or mehrkreisige - warming zone without cooktops and so on. The housing 1 has a seal 24 towards the bottom door 7.

The control panel 12 is arranged mainly at the front of the bottom door 7. There are alternatively other arrangements conceivable, for. B. at the front of the housing 1, divided into different sub-fields and / or partially Side surfaces of the cooking appliance. Further designs are possible. The controls 11 are not limited in their design and can, for. B. z. As control knob, toggle switch, pushbuttons and membrane keys include the display elements 14 include z. B. LED, LCD and / or touchscreen displays.

In Fig. 5 is schematically and not to scale a high-mounted cooking appliance shown from the front, in which the bottom door 7 is open on contact with the worktop 8. The closed state is shown in dashed lines.

In this embodiment, two traversing panels 25 are located on the front side of the fixed housing 1. Each traversing panel 25 comprises two pushbuttons, namely an upper CLOSE button 25a for a bottom door 7 traveling upwards in the closing direction and a lower OPEN button 25b for one Without automatic operation (see below) moves the bottom door 7 only by continuous simultaneous pressing the CLOSE buttons 25a both traversing panels 25 upwards, if possible; also moves the bottom door 7 only by continuous simultaneous pressing of the UP buttons 25b both traversing panels 25 down, if possible (manual operation). Since in manual operation an increased operator attention of the user is given and also both hands are used here, an anti-trap is then optional. In an alternative embodiment, traversing panels 26 are mounted on opposite outer sides of the housing 1 with corresponding ZU buttons 26a and UP buttons 26b, as shown in dotted lines.

The dot-dashed control circuit 13, which is located inside the bottom door 7 behind the control panel 12, the drive motor 9 switches so that the bottom door 7 gently anfährt, d. H. not abruptly by simply hiring the drive motor 9, but by means of a defined ramp.

In this exemplary embodiment, the control circuit 13 comprises a memory unit 27 for storing at least one destination or travel position P0, P1, P2, PZ of the bottom door 7, preferably with volatile memory components, eg. B. DRAMs. If a target position P0, P1, P2, PZ is stored, the bottom door can move independently after actuation of one of the keys 25a, 25b and 26a, 26b of the traversing panels 25 and 26 in the set direction until the next target position is reached or one of the buttons 25a, 25b and 26a, 26b again is pressed (automatic mode). In this embodiment, the lowest target position PZ corresponds to the maximum opening, the (zero) position P0 corresponds to the closed state, and P1 and P2 are freely adjustable intermediate positions. If the last target position for one direction has been reached, manual operation must also be continued if this is possible (ie the last end positions do not correspond to a maximum open or closed final state). Analog must then, if for one direction no target position is stored - which z. B. for an upward movement into the closed position would be the case if only PZ is stored, but not P0, P1, P2 - are driven in this direction in manual mode. If no target position is stored, eg. B. in a new installation or after a power disconnection, no automatic mode is possible. If the bottom door 7 is moved in automatic mode, an anti-pinch protection is preferably activated.

Automatic mode and manual operation are not mutually exclusive: by permanently actuating the positioning panel (s) 25, 26, the bottom door 7 also moves in manual mode if a target position could be approached in this direction. It can be z. B. a maximum actuation time of the traversing fields 25 and 26, respectively, of the associated keys 25a, 25b and 26a, 26b, are set to activate the automatic mode, z. B. 0.4 seconds.

A target position P0, P1, P2, PZ may be any position of the bottom door 7 between and including the zero position P0 and the maximum open position PZ. However, the maximum stored opening position PZ need not be the position with abutment on the work surface 8. Storing the target position P0, P1, P2, PZ can with the bottom door 7 at the desired target position P0, P1, P2, PZ, by, for example, lasting several seconds (eg, lasting two seconds), pressing a confirmation key 28 in the control panel 12th be performed. Existing optical and / or acoustic signal transmitters which output corresponding signals after storing a target position are not shown for the sake of clarity. A start-up of the desired target position P0, P1, P2, PZ to be set takes place, for example, by - in this embodiment - ambidextrous operation of the movement panels 25 or 26 and manual method to this position.

In the memory unit 27, only one or, as shown in this embodiment, a plurality of target positions P0, P1, P2, PZ can be einspeicherbar.

In the case of several target positions P0, P1, P2, PZ, these can be approached successively by actuating the corresponding travel keys 25a, 25b or 26a, 26b. Through several target positions P0, P1, P2, PZ, the high-installation cooking appliance can be easily adapted to the desired operating height of multiple users. The target position (s) are advantageously erasable and / or overwritten. In one embodiment, for example, only one target position can be stored in the opened state, while the zero position P0 is automatically recognized and can be approached automatically. Alternatively, the zero position P0 must be stored in order to be automatically approachable.

It is particularly advantageous for ergonomic use if the or a target position P1, P2, PZ opens the bottom door 7 at least about 400 mm to about 540 mm (ie P1-P0, P2-P0, PZ-P0 ≥ 40cm to 54 cm). In this opening dimension the food supports 21 are easy to insert into the support members 20. It is advantageous if the viewing window 4 is mounted approximately at eye level of the user or slightly below, z. B. by means of a template that indicates the dimensions of the cooking appliance.

Not shown is an existing power failure override for bridging of about 1 to 3 s power failure, preferably up to 1.5 s power failure.

The drive motor 9 from FIG. 1 has at least one sensor unit 31, 32 arranged on a motor shaft 30, possibly in front of or behind a transmission, in order to measure a travel path or a position and / or a speed of the bottom door 7. For example, the sensor unit may include one or more induction, reverberation, opto, SAW sensors, and so forth. Here are for easy distance and speed measurement here two Hall (part) elements 31 offset by 180 ° - ie opposite - attached to the motor shaft 30, and a Hallmeßaufnehmer 32 is fixedly mounted at this area of the motor shaft spaced. If a Hall element 31 then moves past the measuring transducer 32 when the motor shaft 30 rotates, a measuring or sensor signal is generated which is, to a good approximation, digital. With (not necessarily) two Hall elements 31, therefore, two signals are output during one revolution of the motor shaft 30. By time evaluation of these signals, z. As their time difference, the speed vL of the bottom door 7 can be determined, for example via comparison tables or a conversion in real time in the control circuit 13. By addition or subtraction of the measuring signals, a travel or a position of the bottom door 7 can be determined.

A speed control can realize the speed, for example via a PWM-controlled power semiconductor.

For zero point determination, the distance measurement is automatically re-adjusted by initialization in the zero position P0 of the bottom door 7 at each start, so z. B. a faulty sensor signal output or recording is not traditional.

The drive motor 9 is operated by actuation of both traversing panels 25 and 26, even when the main switch 29 is turned off.

Instead of two separate switches per traversing field 25, 26 and a single switch per traversing field is possible, for. B. a toggle switch with a neutral position, which switches only under pressure. Other shapes are possible. Also, the nature and arrangement of the controls 28,29 of the control panel 12 is not limited.

The arrangement and distribution of the control circuit 13 is flexible and not limited, so it can be several boards, z. B. include a display board, a control board and an elevator board, which are spatially separated.

A 4 mm opening dimension can be detected by limit switches 33, which deactivate anti-pinch protection when actuated.

The high-installation cooking appliance can also be designed without a storage unit 27, in which case no automatic operation is possible. This can be for increased operating safety, eg. B. as protection against pinching, be useful.

Fig. 6 shows the control panel 12 of Fig. 5 in more detail. The control panel 12 includes a left display panel 34, a center display panel 35, and a right display panel 36, which in this figure represent all possible displays, such as display panels. In the left display field 34 mode symbols, in the middle display field 35 a time, cooking time or other useful for the set mode parameters and the right display panel 36 a three-digit alphanumeric display 37, a temperature unit display 38 (here on ° C and ° F is adjustable) and a step indicator 39. Below is a series of switches 40-51, viz

• a main switch button 40 to the on and off switch of the device, possibly with time delay,
• a key button 41 for locking the device,
• an arrow-down key 42 for selecting individual modes in descending order,
• an arrow-up key 43 for selecting individual operating modes in ascending order,
• a furnace lamp or a light switch 44 for actively switching a furnace lighting (not shown) by the user,
• a clock button 45 for selecting individual time functions, eg. B. baking time, etc.,

• a Schnellaufheiztaste 50 for switching on and off a Schnellaufheizfunktion and
• an OK button. Confirmation key 51 as activation key, z. B. for time functions and modes.

In this embodiment, the mode selection circuit thus uses two separate arrow keys 42,43 and possibly the confirmation key 51. By operating the mode selector, the cooking device can be switched between different functionalities. The operating modes are cycled through. The mode selector circuit is not limited to the embodiment shown here.

Mode switching 42, 43, 51 will now be described in more detail with reference to the example of switching between oven functionality and cooker functionality.

FIG. 7 shows the display of the control panel of FIG. 6 in a furnace functionality triggered by the corresponding actuation of the arrow keys 42 and 43, respectively. In this case, the high-installation cooking appliance is in the in Fig. 2 schematically shown closed position. In the closed position, the high-installation cooking appliance operates as an oven, wherein the right display panel 36 in the alphanumeric subfield 37 indicates a temperature in the cooking chamber, which is given in degrees Celsius (° C) in this example. The temperature display can also be switched to Fahrenheit, for example. The temperature in the oven is reduced by the minus button 48 and increased by the plus button 49. In the middle panel 35 z. B. a cooking time or remaining cooking time can be displayed. The level indicator 39 is turned off. The left display 34 indicates the icon associated with the operating mode.

FIG. 8 shows the display panel 12 of FIG. 6 in a hob or hob function. This is in the open state of the cooking appliance, as shown in Fig. 1, active, wherein a hotplate or the / the associated heating element is driven. This functionality is switched by pressing the arrow keys 42 and 43, which here correspond to the mode selector. The switching can also include an automatic procedure of the bottom door in the position associated with the selected operating mode. In the cooking area functionality, instead of the temperature unit display 38, the level display 39 is now shown in the right display field 36, while the alphanumeric display 37 now shows the cooking level instead of a temperature. The minus button 48 and the plus button 49 switch the cooking level, z. B. between 0 and 9, down or up.

In Figs. 7 and 8, the key assignment can thus be switched depending on the selected mode, z. B. from a selection of the temperature to a selection of cooking levels and back through the minus or plus buttons 48, 49, and only relevant displays are displayed. The corresponding setting of the control panel 12 may, for. B. by the control circuit 13 shown in Fig. 4, possibly also acting as a display board part thereof happen.

In the switching shown in FIGS. 7 and 8 there is the advantage that no additional switch is required for switching between furnace functionality and hob functionality.

Of course, the nature of the switches 40-51 is not limited and may include any suitable type of switch, e.g. Gag, rotary switch, toggle switch, pushbutton switch, foil switch, thermal sensor switch and so on. For example, the mode selector can alternatively spin Rotary switch instead of the two arrow keys 42, 43 have. By using this rotary switch, the number of switches could even be further reduced.

Also, the invention is not limited to a particular mode of operation or functionality. For example, it is also possible to switch between a keep-warm function in the open and in the closed state. In addition, the list of keys 40-51 listed in the exemplary embodiments is not exhaustive; Depending on functionality and scope of comfort, fewer or more buttons may be provided.
