Description

Die Erfindung betrifft ein Haushaltgerät mit mindestens einer Lichtquelle zur Erzeugung einer projektion zur Darstellung eines Betriebszustandes und mindestens einer Tür und/oder einer Schublade mit einer Betätigungshandhabe.The invention relates to a household appliance having at least one light source for generating a projection for displaying an operating state and at least one door and / or a drawer with an actuating handle.

Aus der DE 102 59 763 A1 ist ein Haushaltgerät mit einer optischen Betriebsanzeige bekannt. Die optische Betriebsanzeige weist eine Lichtquelle auf, die an der Vorderseite eines Sockels oder an einem unteren Rand einer Außentür angeordnet ist. Mit Hilfe einer optischen Vorrichtung wird das von der Lichtquelle abgestrahlte Signallicht auf eine auf einem Fußbodenbereich angeordnete Projektionsfläche projiziert, um vier Betriebszustände "Reinigen, Klarspülen, Trocknen, Fertig" darzustellen.
Nachteilig bei dieser Lösung ist jedoch, dass der Fußbodenbereich verschmutzt sein könnte. Größere Gegenstände, insbesondere Küchenabfälle könnten die Projektion verzerren, so dass der Betriebszustand nicht eindeutig vom Benutzer abzulesen ist. Wenn der Benutzer im Bereich der Projektionsfläche arbeitet oder steht, wird die Projektion auf seinem Körper projiziert und dadurch verzerrt, so dass der Betriebszustand des Haushaltgeräts nicht mehr genau ablesbar ist.From the DE 102 59 763 A1 is a household appliance with an optical power indicator known. The optical power indicator has a light source disposed on the front of a pedestal or on a lower edge of an outer door. With the aid of an optical device, the signal light emitted by the light source is projected onto a projection surface arranged on a floor area in order to represent four operating states "cleaning, rinsing, drying, finished".
The disadvantage of this solution, however, is that the floor area could be dirty. Larger objects, in particular kitchen waste could distort the projection, so that the operating state is not clearly read by the user. If the user is working or standing in the area of the projection surface, the projection is projected on his body and thereby distorted, so that the operating state of the household appliance is no longer accurately readable.

Aus der DE 102 59 762 A1 ist ein Haushaltgerät mit einer Gerätefrontverkleidung vor einer Vordertür und mit wenigstens einer optischen Betriebsanzeige, welche in einem eingebauten Zustand des Haushaltgeräts und/oder bei geschlossener Vordertür verborgen ist, sowie mit wenigstens einem Lichtleiter zur Übertragung eines von der optischen Betriebsanzeige abgestrahlten Signallichts bekannt. Dabei befindet sich die optische Betriebsanzeige außerhalb eines oberen Rands der Vordertür. Gemäß einer Ausführungsform kann an der Gerätefrontverkleidung auch ein Gerätegriff montierbar sein, der den Lichtleiter derart umfasst, dass das von der optischen Betriebsanzeige abgestrahlte Signallicht im Gerätegriff sichtbar ist.From the DE 102 59 762 A1 is a household appliance with a front panel front of a front door and with at least one optical power indicator, which is hidden in a built-in state of the household appliance and / or closed front door, and at least one light guide for transmitting a radiated from the optical power indicator signal light known. The optical status indicator is located outside an upper edge of the front door. According to one embodiment, a device handle can also be mounted on the front panel of the device, which comprises the light guide in such a way that the signal light emitted by the optical operating display is visible in the device handle.

Um den Stand der Technik zu verbessern liegt der Erfindung daher die Aufgabe zugrunde, bei Haushaltgeräten der eingangs näher beschriebenen Art, die von der Lichtquelle erzeugte Projektion an einem Ort zu projizieren, wo die Projektion keine Verzerrung aufweist und der Betriebszustand eindeutig abzulesen ist.In order to improve the prior art, the invention is therefore based on the object, in household appliances of the type described in more detail, to project the projection generated by the light source at a location where the projection has no distortion and the operating state is clearly read.

Erfindungsgemäß ist vorgesehen, dass die Betätigungshandhabe eine Griffmulde aufweist, in der die Projektion angeordnet ist. Diese Lösung bietet den Vorteil, dass die Projektion gut zu erkennen und immer im Blickfeld des Benutzers angeordnet ist.According to the invention it is provided that the actuating handle has a recessed grip, in which the projection is arranged. This solution has the advantage that the projection is easy to recognize and always in the field of vision of the user.

Durch diese Anordnung ist sichergestellt, dass alle Betriebszustände an der Betätigungshandhabe scharf dargestellt werden. Der Benutzer ist somit in der Lage, ohne Probleme den Betriebszustand des Haushaltgerätes abzulesen. Ferner kann der unmittelbar vor der Tür stehende Benutzer die Projektion besser sehen, weil sie sich im Blickfeld des Benutzers befindet.By this arrangement it is ensured that all operating conditions are displayed sharply on the actuating handle. The user is thus able to read the operating state of the household appliance without any problems. Furthermore, the user standing right in front of the door can see the projection better, because it is in the field of vision of the user.

Nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, dass die Lichtquelle zur Erzeugung der Projektion an einer Innenseite der Betätigungshandhabe angeordnet ist.
Diese Lösung zeichnet sich dadurch aus, dass genügend Montageraum zur Verfügung steht. Ebenfalls ist die Lichtquelle bei möglichen Reparaturarbeiten für einen Mechaniker leichter zugänglich.According to a further preferred embodiment of the subject matter of the invention, it is provided that the light source for generating the projection is arranged on an inner side of the actuating handle.
This solution is characterized by the fact that sufficient mounting space is available. Also, the light source is more easily accessible to a mechanic for possible repair work.

Nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, dass die Lichtquelle zur Erzeugung der Projektion an der Griffmulde der Betätigungshandhabe angeordnet ist.
Diese Lösung zeichnet sich besonders dadurch aus, dass lange Verkabelungswege ausgeschlossen sind, da die Lichtquelle im Nahbereich der Steuer- und/oder Regelungselektronik angeordnet ist. Aufgrund der kurzen Verkabelungswege ist diese Lösung kostengünstig durchzuführen.According to a further preferred embodiment of the object of the invention it is provided that the light source for generating the projection is arranged on the recessed grip of the actuating handle.
This solution is particularly characterized by the fact that long cabling paths are excluded because the light source is located in the vicinity of the control and / or regulating electronics. Due to the short cabling routes, this solution is inexpensive to carry out.

Besonders einfach ist der Einbau der Lichtquelle, wenn nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, dass die Lichtquelle zur Erzeugung der Projektion zurückversetzt und/oder vorgesetzt an der Betätigungshandhabe angeordnet ist.Particularly simple is the installation of the light source, if it is provided according to a further preferred embodiment of the subject invention that the light source for generating the projection is set back and / or pre-set on the actuating handle.

Insbesondere, wenn die Lichtquelle zurückversetzt angeordnet ist, ist diese vor ungewollten Einflüssen geschützt. Wenn die Lichtquelle vorgesetzt angeordnet ist, so ist die Lichtintensität der Lichtquelle stärker da die Lichtstrahlen auch seitlich von der Lichtquelle abstrahlen können.In particular, when the light source is arranged set back, it is protected from unwanted influences. If the light source is placed in front, then the light intensity of the light source is stronger because the light rays can also radiate laterally from the light source.

Bei einer weiteren vorteilhaften Ausgestaltung des Gegenstandes der Erfindung ist vorgesehen, dass der Lichtquelle zur Erzeugung der Projektion mindestens ein von Weiß unterschiedlicher Farbton zur Visualisierung des Betriebszustandes zugeordnet ist.In a further advantageous embodiment of the object of the invention, it is provided that the light source for generating the projection is associated with at least one color different from white for visualizing the operating state.

Der wesentliche Vorteil besteht darin, dass der Benutzer stets in der Lage ist, den Status des Betriebszustands aufgrund der Farbkombination zu erkennen. Durch die Variation der verschiedenen Farben kann einem Programm oder einen Teilprogrammschritt eine Kombination von Farben zur Beschreibung des Betriebszustandes zugeordnet werden. So kann der Benutzer aufgrund der projizierten Farben erkennen, dass beispielsweise der Betrieb beendet ist und er das Haushaltgerät abzuschalten kann.The main advantage is that the user is always able to recognize the status of the operating state due to the color combination. By varying the different colors, a program or a partial program step can be assigned a combination of colors for describing the operating state. Thus, the user can recognize from the projected colors that, for example, the operation is finished and he can turn off the household appliance.

Eine besonders kostengünstige Lösung besteht darin, dass die Lichtquelle zur Erzeugung der Projektion als LED ausgebildet ist.A particularly cost-effective solution is that the light source for generating the projection is designed as an LED.

Entsprechend einer weiteren vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass der Lichtquelle ein optisches Übertragungsmittel zugeordnet ist.
Eine entsprechend dieser Merkmale ausgestattete Vorrichtung zeichnet sich dadurch aus, dass durch das optische Übertragungsmittel die Projektionsfläche auch zusätzlich noch an einem anderen Ort projiziert werden kann, der für den Benutzer noch bedienungsfreundlicher ist. Des Weiteren bietet diese Lösung den Vorteil, dass das optische Übertragungsmittel kostengünstig in ihrer Herstellung ist und einfach zu montieren ist.According to a further advantageous embodiment of the invention it is provided that the light source is associated with an optical transmission means.
A device equipped in accordance with these features is characterized in that the projection surface can also be additionally projected at a different location by the optical transmission means, which is even more user-friendly for the user. Furthermore, this solution offers the advantage that the optical transmission means is inexpensive to manufacture and easy to assemble.

Gemäß einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, dass das optische Übertragungsmittel an der Innenseite der Betätigungshandhabe angeordnet ist.

Nach einer weiteren Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, dass das optische Übertragungsmittel in der Griffmulde der Betätigungshandhabe angeordnet ist.
Die Lösung zeichnet sich dadurch aus, dass der Einbau in die Griffmulde sehr einfach und kostengünstig durchzuführen ist.According to a further embodiment of the object of the invention it is provided that the optical transmission means is arranged in the recessed grip of the actuating handle.
The solution is characterized by the fact that the installation in the recessed grip is very easy and inexpensive to perform.

Nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, dass das optische Übertragungsmittel als ein Reflektor oder eine Linse ausgebildet ist.According to a further preferred embodiment of the object of the invention it is provided that the optical transmission means is formed as a reflector or a lens.

Der wesentliche Vorteil besteht darin, dass der Reflektor und die Linse sehr kostengünstig in ihrer Herstellung sind. Ferner kann die Schärfe des auf der Projektionsfläche projizierten Betriebszustandes mittels einer Linse verbessert werden kann. Dadurch kann der Benutzer den Betriebszustand besser ablesen.The main advantage is that the reflector and the lens are very inexpensive to manufacture. Furthermore, the sharpness of the operating state projected on the projection surface can be improved by means of a lens. This allows the user to better read the operating condition.

Entsprechend einer weiteren vorteilhaften Ausführungsform ist vorgesehen, dass die Griffmulde der Betätigungshandhabe über die gesamte Breite der Tür angeordnet ist.
Der wesentliche Vorteil besteht darin, dass der Benutzer die Griffmulde der Betätigungshandhabe ertasten kann, ohne die Betätigungshandhabe anzusehen, so dass dadurch ein weiterer Arbeitsschritt "Ansehen der Betätigungshandhabe" für den Benutzer entfällt.According to a further advantageous embodiment, it is provided that the recessed grip of the actuating handle is arranged over the entire width of the door.
The main advantage is that the user can feel the recessed handle of the actuating handle, without looking at the actuating handle, thereby eliminating the need for a further step "viewing the actuating handle".

Nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, dass die Betätigungshandhabe als wenigstens zwei Schenkel aufweisendes Profil ausgebildet ist, dass über die gesamte Breite der Tür angeordnet ist.

Die Tür 3 lässt sich über eine Betätigungshandhabe 6 öffnen, die ein Profil 7 und eine Griffmulde 8 umfasst. Die Oberseite der Außentür 4 und das Profil 7 sind kraftschlüssig mit Hilfe von zwei Schrauben 9 miteinander verbunden. Alternativ kann das Profil 7 auch an die Außentür 4 geklebt werden. Das Profil 7 weist zwei Schenkel auf, die L-förmig ausgebildet sind und über die gesamte Breite der Außentür 4 angeordnet. Alternativ kann das Profil auch U-förmig ausgebildet sein, wobei die Schenkel des U-förmigen Profils gleiche oder unterschiedliche Längen aufweisen können. An dem senkrecht zur Tür stehenden Schenkel des Profils 7 ist eine Anzeige- und Bedienvorrichtung 9 angeordnet, die vorzugsweise als eine Touch-Screen-Anzeige- und Bedienvorrichtung ausgebildet ist. Alternativ kann die Anzeige- und Bedienvorrichtung 9 elektromechanische Bauelemente wie beispielsweise Tasten aufweisen. An der Außentür 4 ist die Griffmulde 8 eingeformt, die über die gesamte Breite der Außentür 4 verläuft. Innerhalb der Griffmulde 8 ist eine Projektionsfläche 11 angeordnet, der je nach Betriebszustand mindestens eine Farbe zugeordnet ist.In FIG. 1 is a dishwasher 1 with a housing 2 is shown, the inner shell forms a treatment space, not shown, in which a storage container, not shown, is arranged for storage of goods to be cleaned. The treatment room is accessible via a door 3, which has an outer door 4 and an inner door 5. The door 3 can be opened via an actuating handle 6, which comprises a profile 7 and a recessed grip 8. The top of the outer door 4 and the profile 7 are non-positively connected by means of two screws 9. Alternatively, the profile 7 can also be glued to the outer door 4. The profile 7 has two legs, which are L-shaped and arranged over the entire width of the outer door 4. Alternatively, the profile may also be U-shaped, wherein the legs of the U-shaped profile may have the same or different lengths. At the leg of the profile 7, which is perpendicular to the door, a display and operating device 9 is arranged, which is preferably designed as a touch-screen display and operating device. Alternatively, the display and control device 9 electromechanical components such as buttons have. On the outer door 4, the recessed grip 8 is formed, which extends over the entire width of the outer door 4. Within the recessed grip 8, a projection surface 11 is arranged, which is associated with at least one color depending on the operating state.

In der Figur 2 ist die Geschirrspülmaschine 1 in Seitenansicht gezeigt. Die in der Tür 2 angeordnete Griffmulde 8, weist eine Lichtquelle 12 auf, die zurückversetzt angeordnet ist. Die Lichtquelle 12 ist in diesem Ausführungsbeispiel als eine LED ausgebildet. Es ist jedoch auch möglich eine Laserdiode zu verwenden. Alternativ können auch mehrere Lichtquellen 12 verwendet werden, die jeweils unterschiedliche oder gleiche Farben aufweisen. Die Farben können beispielsweise durch eine Färbung der Schutzhülle der Lichtquelle 12 erzeugt werden. Die Lichtquelle 12 ist mit einer Steuer- und Regelungselektronik 13 verbunden, in der mehrere Programme abgespeichert sind, die die Teilprogrammschritte "Vorspülen", "Reinigen", "Zwischenspülen", "Klarspüten", "Trocknen" aufweisen. An der oberen Innenseite des Profils 7 ist ein Reflektor 14 angeordnet, der die von der Lichtquelle 12 erzeugten Lichtstrahlen auf die in der Griffmulde 8 angeordnete Projektionsfläche 11 umlenkt. Auf einen als optisches Übertragungsmittel 14 ausgebildeten Reflektor kann verzichtet werden, wenn die Lichtquelle 12 so in der Griffmulde 8 angeordnet ist, dass der Benutzer die Lichtquellen sehen kann, ohne das diese von dem Profil 7 verdeckt werden.In the FIG. 2 the dishwasher 1 is shown in side view. The arranged in the door 2 recessed grip 8, has a light source 12, which is arranged set back. The light source 12 is formed in this embodiment as an LED. However, it is also possible to use a laser diode. Alternatively, it is also possible to use a plurality of light sources 12 which each have different or the same colors.

Während des Betriebes kann mittels von Balken, die auf der Projektionsfläche 11 projiziert sind, in verschiedenen Farben die Betriebsdauer angezeigt werden. So kann jeder einzelne Teilprogrammschritt durch Balken angezeigt werden. Nach Beendigung des jeweiligen Teilprogrammschritts erlischen die Balken, so dass der Benutzer stets darüber informiert ist, in welchem Betriebszustand sich die Geschirrspülmaschine befindet. Wenn der Betrieb der Geschirrspülmaschine 1 beendet ist, kann beispielsweise durch eine mit grünen Balken dargestellte Projektion auf der Projektionsfläche 11 dem Benutzer kenntlich gemacht werden, dass die Geschirrspülmaschine 1 zum Entladen des zu behandelnden Gutes bereit ist. Wenn die Projektion auf der Projektionsfläche 11 grün erleuchtet, kann der unmittelbar vor der Tür stehende Benutzer diese erkennen. Er kann die Betätigungshandhabe 6 greifen oder ertasten, da sie über die gesamte Breite der Außentür 4 angeordnet ist und die Tür 3 öffnen. Nachdem die Tür 3 geöffnet ist, kann der Benutzer die Geschirrspülmaschine 1 über die Anzeige- und Bedienvorrichtung 9 ausschalten.After the dishwasher 1 has been loaded, the user uses the display and operating device 9 to put the dishwasher 1 into operation. Depending on the operating state, the light source 12 is activated by the control and regulating electronics 13, so that the light beams from the light source 12 hit the reflector formed as an optical transmission means 14 and are deflected via this onto the projection surface 11. When using a lens as an optical transmission means 14, the quality of the image of the operating state projected on the projection surface 11 is produced distinctly sharper. A further improvement of the imaging quality of the projection of the operating state brings a combination of a mirror with a lens.
Depending on the operating state, the color of the projection generated by the light source 12 is changed. At the beginning of the operation, for example, the color can be selected red for the projection, so that the user recognizes that the device is in operation. During operation, by means of bars which are projected on the projection surface 11, the operating time can be displayed in different colors. This means that each individual program step can be displayed by bars. After completion of the respective part program step, the bars go out, so that the user is always informed about the operating state of the dishwasher. When the operation of the dishwasher 1 has ended, the user can be made aware, for example, by a projection with green bars on the projection surface 11, that the dishwasher 1 is ready for unloading the material to be treated. If the projection on the projection surface 11 lights up green, the user standing directly in front of the door can recognize it. He can grasp or feel the actuating handle 6, since it is arranged over the entire width of the outer door 4 and open the door 3. After the door 3 is opened, the Users turn off the dishwasher 1 via the display and control device 9.
