Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The invention relates to a domestic appliance with a door leaf which includes a recessed handle. The domestic appliance is a domestic refrigeration appliance in particular. 
     WO 2011/124738 A2 discloses a domestic refrigeration appliance with a door leaf. The door leaf has a front outer wall, a rear inner wall and at least one side wing. The door leaf comprises a grip tray with a recessed handle which can be accessed by way of an opening in the side wing. 
     BRIEF SUMMARY OF THE INVENTION 
     It is the object of the present invention to specify an improved domestic appliance, in particular an improved domestic refrigeration appliance with a door leaf, which features a recessed handle. 
     The object of the invention is achieved by a domestic appliance, having an interior chamber, an electronic control apparatus which has an electronics system and which is designed to control at least one function of the domestic appliance during operation of the domestic appliance, a door leaf for opening and closing the interior chamber, said door leaf having an inner face which faces the interior chamber and an outer face which faces away from the interior chamber and a recessed handle arranged in the outer face of the door leaf and comprising a grip, which forms an indentation in relation to the outer face of the door leaf, as well as a lighting arrangement with at least one lighting means which is designed to illuminate the recessed handle, at least a large part of the electronics system and the at least one lighting means forming a common assembly which is arranged within the door leaf next to the indentation so that the at least one lighting means is able to radiate its light out of the indentation into the recessed handle. The at least one lighting means is preferably configured as at least one LED. 
     The inventive domestic appliance accordingly comprises the control apparatus which controls and optionally also regulates at least one function of the domestic appliance, in particular the operation of the domestic appliance. The inventive domestic appliance also comprises the door leaf. This is preferably supported in such a manner that it can be pivoted in relation to a vertically running axis and comprises a recessed handle in its outer face, which can be used to open the door leaf. The recessed handle comprises the grip which forms an indentation in relation to the outer face of the door leaf. A person&#39;s hand can thus engage in the indentation to open the door leaf. The indentation can be formed for example by a channel in a side wall of the door leaf. 
     The inventive domestic appliance also has the lighting arrangement which is designed to illuminate the recessed handle. The lighting arrangement comprises the at least one lighting means. This is preferably embodied as one or more LEDs. 
     The electronic control apparatus comprises the electronics system, in other words the part of the control apparatus which assumes the control task of the electronic control apparatus. At least a large part, if not all, of the electronics system is arranged within the door leaf. A network part provided to supply the electronics system can also be arranged in the door leaf. However this network part is preferably arranged in or on the body of the domestic appliance. The electronics system comprises for example a microprocessor or a microcontroller, generally electronic and electrical parts. 
     According to the invention the electronics system and the at least one lighting means form the common assembly which is in turn arranged next to the indentation of the door leaf so that the at least one lighting means is able to radiate its light out of the indentation into the recessed handle. 
     The inventive domestic appliance is preferably configured as a domestic refrigeration appliance, the body of which is a thermally insulated body and has an inner container which delimits the interior chamber. The interior chamber of the domestic refrigeration appliance is a chillable interior chamber and is provided for the storage of food. The domestic refrigeration appliance comprises a refrigeration apparatus for chilling the interior chamber. The electronic control apparatus is then designed to control the refrigeration apparatus in such a manner that the interior chamber has at least approximately a setpoint temperature. Control of the refrigeration apparatus, which is preferably embodied as a temperature regulator, therefore represents control of at least one function of the domestic appliance configured as a domestic refrigeration appliance. 
     The inventive domestic refrigeration appliance can be a domestic refrigerator for example. The chillable interior chamber is then chilled to temperatures above 0° C. The inventive domestic refrigeration appliance can also be a domestic freezer. The chillable interior chamber is then chilled to temperatures below 0° C. However the inventive domestic refrigeration appliance can also be a combined refrigerator/freezer. The inventive domestic refrigeration appliance can have just one chillable interior chamber or a number of chillable interior chambers which can also be closed and opened respectively by means of a door leaf. 
     The common assembly preferably comprises a single printed circuit board, to which the at least one lighting means and electrical and electronic parts of the electronics system are fastened. This embodiment can be relatively compact. 
     According to one preferred embodiment of the inventive domestic appliance a hollow space is arranged next to the indentation of the recessed handle, the common assembly being fastened therein, the indentation comprising a wall separating the hollow space and the recessed handle with at least one opening, through which the light from the at least one lighting means is able to radiate to illuminate the recessed handle. The hollow space can be formed in particular by a housing within the door leaf. The housing is preferably open in the direction of the outer face and closed by means of a cover in this region, thus facilitating the mounting of the door leaf. The cover preferably runs flush with the outer face. 
     If the inventive domestic appliance is configured as a domestic refrigeration appliance, the hollow space in which the assembly is fastened can thus be arranged next to the indentation of the recessed handle, the indentation comprising the wall separating the hollow space and the recessed handle with the at least one opening, through which the light from the at least one lighting means is able to radiate to illuminate the recessed handle. According to this variant the outer face of the door leaf in particular has an outer skin which adheres to the insulating foam and which comprises a cutout, in which a recess forming the hollow space is arranged with a housing for the assembly which is manufactured as a single piece and open in the direction of the outer face in the insulating foam, being covered by means of a cover in an outward direction. The cover preferably runs flush with the outer skin. This open housing is preferably made of plastic. The use of the open housing means that the door leaf can be manufactured relatively simply as it is relatively simple to manufacture the door leaf with the open housing including insulating foam first and then fasten the common assembly within the housing, connect it to electric cables and then close the housing with the cover. 
     According to one variant of the inventive domestic appliance the lighting arrangement has a light guide coupled optically to the at least one lighting means, said light guide being coupled optically to the at least one opening. The opening is configured for example as a slot. The light guide allows relatively uniform illumination of the recessed handle to be achieved. The light guide can also be part of the common assembly. 
     The light guide can preferably close off the at least one opening, preferably closing it completely. The light guide thus preferably forms at least a part of the wall separating the hollow space and the recessed handle. 
     According to a further variant of the inventive domestic appliance the recessed handle has a depression, which is only partially covered by the grip forming the indentation. Therefore a person&#39;s hand can engage in the indentation by way of the depression to open the door leaf. As the at least one lighting means is also able to radiate its light from the indentation into the recessed handle, the depression is also illuminated. The depression is preferably selected such that it reaches to the corresponding side wall of the door leaf. 
     According to one preferred variant of the domestic appliance the door leaf can be pivoted in relation to a vertical axis. The inventive domestic appliance can also have a further door leaf which is arranged next to the door leaf, can be pivoted in relation to a vertical axis, has an inner face and an outer face and comprises a further recessed handle arranged in the outer face of the further door leaf, said further recessed handle comprising a grip which forms an indentation in relation to the outer face of the further door leaf. 
     The recessed handle of the door leaf is preferably arranged in the region of the side face of the door leaf facing the further door leaf. The further recessed handle of the further door leaf is preferably arranged in the region of the side face of the further door leaf facing the door leaf. The two recessed handles are preferably at the same height so the lighting arrangement is also able to illuminate the further recessed handle. If the recessed handle comprises the depression for example, said depression preferably reaches to the side face of the door leaf facing the further door leaf. The further recessed handle can be embodied in the same manner as the recessed handle, in other words can also comprise a depression which then however reaches to the side face of the further door leaf facing the door leaf. However the further recessed handle can also be embodied simply as a channel which is arranged in the side face of the further door leaf facing the door leaf. The length of this channel preferably corresponds to the depth of the depression of the recessed handle of the door leaf. It is therefore possible for the channel of the further door leaf to be illuminated by way of the depression of the recessed handle. 
     If the inventive domestic appliance is a domestic refrigeration appliance, the recessed handle can in particular have said depression, its walls being molded on the open housing for the assembly. 
     The inventive domestic appliance provides a combination of electronics system and grip in one element (common assembly). It is therefore optionally possible for the printed circuit board, to which the electrical and electronic parts and the at least one lighting means are fastened, to be arranged directly next to the recessed grip or handle. If the at least one lighting means is LEDs which are fastened to the printed circuit board, said LEDs can radiate laterally into the recessed handle for example directly or by way of a light guide. Their light can therefore illuminate the point of engagement. 
     The lighting arrangement can also be used to visualize switching states or alarm states of the domestic appliance. For example in the case of a door alarm the light of the lighting arrangement can assume a defined color, for example red. The door alarm is activated for example when the door leaf is open for a predefined time period. The lighting arrangement can optionally also flash with the alarm. 
     A so-called “holiday function” (standby function) for example could be indicated by white light from the lighting arrangement, in particular increasing and decreasing in intensity slowly, changing brightness at the speed of slow breathing. 
     The visualization of further functions such as “eco cooling” (energy saving mode) for example can be visualized by green light for example or “super” can be visualized by bright white light. 
     The lighting arrangement can optionally also be embodied as interactive, in that for example the electronics system automatically activates the at least one lighting means when a person approaches the inventive domestic appliance or the recessed handle. To this end the domestic appliance can comprise for example a distance or proximity sensor which is connected to the electronics system. The distance or proximity sensor can be fastened in or to the outer face of the door leaf for example.

The recessed handle  5  of the second door leaf  3  is arranged in the region of the side face of the second door leaf  3  facing the first door leaf  2 . The two recessed handles  4 ,  5  are at the same height. 
     In the present exemplary embodiment the inner face of the first door leaf  2  is formed by an inner skin  6 . The inner skin  6  is made of plastic or metal for example. The several door trays of the first door leaf  2 , if present, can be arranged on the inner skin  6 , it being possible for fastening devices for the door trays to be molded on the inner skin  6 . 
     A peripheral seal  10  is preferably fastened to the inner skin  6 , sealing the first chillable interior chamber when the first door leaf  2  is closed. The seal  10  is fastened for example by means of holders molded on the inner skin  6 . 
     In the present exemplary embodiment the outer face  7  of the first door leaf  2  is formed at least mostly by an outer skin  9 . The outer skin  9  is made of plastic or metal for example. The materials of the inner skin  6  and outer skin  9  can be the same or different. 
     The first door leaf  2  has the vertically running first side face  8  facing the second door leaf  3  and a second side face opposite the first side face  8 , in the region of which second side face the first door leaf  2  is hinged to the body for example by means of the hinges. 
     The first side face  8  and the second side face of the first door leaf  2  can be formed by the inner skin  6 , as shown in  FIG. 2 . 
     The hollow space formed by the inner face and the outer face  7  of the first door leaf  2  is filled in particular with an insulating foam  11 , to which the inner skin  6  and outer skin  9  in particular adhere. 
     In the present exemplary embodiment the recessed handle  4  of the first door leaf  2  is formed in that a depression  12  corresponding to the size of the recessed handle  4  is formed in the outer face  7  of the first door leaf  2  in the region of said recessed handle  4 .

     In the present exemplary embodiment the front wall  17   c  of the hollow space  17  is preferably formed by a second part  19 . The second part  19  is preferably made of metal but can also be made of plastic. The second part  19  is in particular a cover covering the hollow space  17 . The cover or second part  19  preferable runs flush with the outer skin  9 . 
     The second part  19  is in particular embodied in such a manner that it also forms the surface  14  of the grip  13  running flush with the surface of the outer skin  9  or serves as a cover for the grip  13 .  FIG. 4  shows the part of the first door leaf  2  shown in  FIG. 3  without the second part  19 . 
     The hollow space  17  is provided to hold the electronic control apparatus of the domestic refrigeration appliance  1 , or at least its electronics system  20  or at least a large part of the electronics system  20 . A network part of the electronic control apparatus is preferably fastened in or to the body of the domestic refrigeration appliance  1  so that no cables carrying a network voltage have to be passed through the first door leaf  2  to the electronics system  20 . Electric cables required for the operation of the electronics system  20  are laid in particular in the insulating foam  11  of the first door leaf  2  and are not shown for the sake of clarity. 
     The electronics system  20  fastened within the hollow space  17  comprises in particular a printed circuit board, to which electrical and electronic parts, for example a microcontroller or a microprocessor, are fastened. 
     The domestic refrigeration appliance  1  further comprises a lighting arrangement provided to illuminate the recessed handle  4  of the first door leaf  2 . This is configured in particular in such a manner that it illuminates the depression  12  and by way of the depression  12  also the recessed handle  5  of the second door leaf  5 , in particular its indentation configured as the channel  5   a.    
     The lighting arrangement of the recessed handle  4  is arranged in such a manner that it radiates its light out of the indentation  16  of the recessed handle  4 . 
     The lighting arrangement comprises at least one lighting means, preferably in the form of at least one LED  21 . The at least one lighting means or the at least one LED  21  is combined with the electronics system  20  of the assembly  22  in that for example the at least one lighting means or the at least one LED  21  is fastened to the printed circuit board of the electronics system  20 . The electronics system  20  and the at least one lighting means or the at least one LED  21  are therefore combined to form a single, common assembly in the assembly  22 . 
     In the present exemplary embodiment the hollow space  17  is separated from the recessed handle  4  by the vertical wall  17   d . This vertical wall  17   d  is preferably formed by the first part  18 . Its surface facing away from the hollow space  17  is part of the indentation  16  of the recessed handle  4 . This vertical wall  17   d  can have at least one opening, through which the light from the at least one lighting means or the at least one LED  21  is able to radiate to illuminate the recessed handle  4  of the first door leaf  2  and optionally also the recessed handle  5  of the second door leaf  3 . This at least one opening can be covered by an at least semi-transparent cover. The first part  18  is therefore preferably a housing for the assembly  22  that is open in the direction of the outer face  7  and on which the walls  12   a ,  12   b  forming the depression  12  are molded as a single piece. 
     In the present exemplary embodiment the at least one opening is configured as a vertically running slot  17   e  in the wall  17   d  separating the recessed handle  4  and the hollow space  17 , said slot  17   e  preferably running over the entire height h of the depression  12  or the wall  17   d . In particular the slot  17   e  is provided with a light guide  23 , which in particular completely covers or fills the slot  17   e . The light guide  23  is in turn coupled optically to the at least one lighting means or the at least one LED  21 , so that the light from the at least one lighting means or the at least one LED  21  is able to illuminate the depression  12  or the recessed handles  4 ,  5  by way of the light guide  23 . The light guide  23  is preferably also part of the assembly  22 . 
     The domestic refrigeration appliance  1  can be embodied in such a manner that the lighting arrangement of the recessed handles  4 ,  5  is embodied as what is referred to as a night design. In particular the light from the at least one lighting means or the at least one LED  21  can be colored. A colored filter can also optionally be provided between the light guide  23  and the at least one lighting means. It is also possible for the light guide  23  to be colored. 
     The lighting arrangement can optionally also be embodied as interactive in that for example the electronics system  20  automatically activates the at least one lighting means or the at least one LED  21  when a person approaches the domestic refrigeration appliance  1  or the recessed handle  4 . To this end the domestic refrigeration appliance  1  can comprise for example a distance or proximity sensor  24  which is connected to the electronics system  20 . The distance or proximity sensor  24  can be fastened for example in or to the outer face  7  of the first door leaf  2 , preferably in or to the second part  19 . 
     The lighting arrangement can also be used to visualize switching states or alarm states of the domestic refrigeration appliance  1 . For example in the case of a door alarm the light of the lighting arrangement can assume a defined color, for example red. The door alarm is activated for example when one of the door leaves  2 ,  3  is open for a predefined time period. The lighting arrangement can optionally also flash with the alarm. 
     A so-called “holiday function” (standby function) for example could be indicated by white light from the lighting arrangement, in particular increasing and decreasing in intensity slowly, changing brightness at the speed of slow breathing. 
     The visualization of further functions such as “eco cooling” (energy saving mode) for example can be visualized by green light for example or “super” can be visualized by bright white light.
