Description

The invention relates to a dishwasher, in particular a domestic dishwasher, with a washing compartment providing a washing compartment, which serves to receive items to be cleaned, wherein the washing container for loading with items has a feed opening, which is fluid-tightly closed by means of a rotatably mounted Spülraumtür, and with a arranged outside the washing compartment lighting device.

Dishwashers of the generic type have a washing compartment providing a washing compartment. This is the user side accessible via a feed opening, which is fluid-tightly closed by means of a pivotally mounted flushing door. When used as intended, the washing container serves to receive items to be cleaned, which may be dishes, cutlery pieces and / or the like, for example.

For loading of items to be cleaned with rinsing liquid, the so-called rinsing liquor, the dishwasher has a spray device in the interior of the washing container. This spraying device typically provides rotatably mounted spray arms, wherein usually two or three such spray arms are provided. In the intended use case, a loading of the items to be cleaned with rinse liquor by means of rotating spray arms.

In order to facilitate a user loading and / or emptying of the dishwasher, it is known from the prior art to arrange a light source in the washing compartment provided by the washing compartment. This light source can be switched by means of a door-operated circuit arrangement, so that when the dishwasher door is pivoted from the closed position into an open position, the light source is automatically switched on. Since this light source is used to illuminate the washroom, it is also referred to as washroom lighting.

The arrangement of a light source within the washing compartment can be disadvantageous in that the user is dazzled in the intended use case. Around To meet this disadvantage, it has become known from the prior art to equip a dishwasher with a arranged outside the washing compartment lighting device. Such a lighting device is for example from the DE 10 2004 051 174 A1 according to which the lighting device is formed on the pivotally arranged Spülraumtür.

The embodiment of the DE 10 2004 051 174 A1 However, it is not free from disadvantages. For example, it is particularly problematical that the lighting device is covered by the lower basket when the lower rack is drawn out in accordance with the regulations, so that sufficient illumination of the washing compartment is no longer guaranteed. To counter this problem is with the EP 2 394 557 A2 has been proposed to arrange the lighting device at the top of the feed opening. Advantage of this solution is that a sufficient illumination of an extended lower and / or upper basket is possible. However, it can only take place an insufficient illumination of the washing itself. However, in order to deliver part of the light emitted by the lighting device into the washing compartment provided by the washing compartment, a light guiding device is used which, for example by means of a lens, at least partially diverts the light emitted by the lighting device into the washing compartment.

Although the above-described lighting device has proven itself in everyday practical use, this is not free of disadvantages. So requires one from the EP 2 394 557 A2 Known lighting system a corresponding installation space edge of the feed opening. However, this installation space is not always available, especially not when the dishwasher is designed as a so-called fully integrated machine, in which the user-side to be reached controls the front of the Spülraumtür are arranged. Incidentally, in the known construction of disadvantage that, despite the proposed light-guiding device only insufficient Spülraumausleuchtung is permitted, as arranged in the Türzargenbereich door seal provides shading within the washing compartment.

The US 6700500 B1 shows a dishwasher, in which when opening the dishwasher door a warning light device in the form of a light-emitting cable, which is fixed end side in the upper part of the dishwasher door edge, from the side dishwasher housing is pulled out. This is intended to protect people in the area from injuries caused by the open dishwasher door.

It is to avoid the disadvantages listed above, the object of the invention to further develop a dishwasher to the effect that an improved illumination in particular of the washing compartment is allowed.

To solve this problem, the invention proposes a dishwasher with the features of claim 1.

The illumination device provided according to the invention is adjustable in its relative position to the washing container, it can therefore be transferred from a position of use to a non-use position and vice versa. This embodiment of the invention makes it possible to convert the lighting device in case of need in their position of use, in which position an optimized illumination of the washing compartment is allowed. Despite such an optimized Spülraumausbeleuchtung no larger installation space is required, since due to the movable arrangement of the lighting device in relation to the washing a transferring the same is allowed in a non-use position. In the non-use position, the lighting device is not functional and saves space.

The lighting device has an abutment that interacts with the Spülraumtür. The abutment may be, for example, a contact surface which, in the event of movement of the illumination device, rests on the inside of the flushing chamber door. A transfer of the lighting device from a non-use position to a use position and vice versa can therefore be achieved depending on the Spülraumtürstellung.

However, it is preferred that the lighting device is in the open position when the dishwasher door is open. For this purpose it can be provided to place the lighting device under spring action, so that this moves spring-loaded in its intended use position. However, such a method is only possible with the dishwasher door open, as this otherwise blocks movement of the lighting device. For example, it may be provided that upon opening the flushing door, the lighting device requires spring-loaded automatically transferred to its position of use. Once the Spülraumtür closed again, that is spent from its open position to its closed position, moves the Spülraumtür with its inside wall on the lighting device and counteracts the spring force acting on the lighting device a back process also the lighting device in its non-use position.

As soon as the lighting device has reached its non-use position, the lighting device switches off, which ensures that the lighting device is switched off when the washroom door is closed. Accordingly, an automatic switching on of the lighting device takes place when the lighting device is transferred as a result of a transfer of the Spülraumtür in an open position from the non-use position into a position of use.

According to a first alternative of the invention, the lighting device is formed linearly movable. It can therefore be moved in a straight line. Alternatively, a rotatable embodiment of the illumination device may be provided, in which case the illumination device is rotated about a fixed pivot point. In both cases, it may be provided in the manner already described above that the illumination device moves from a non-use position into a use position or rotates and vice versa.

Structurally, according to a further feature of the invention, it may be provided that the illumination device is accommodated within a housing arranged on the rinsing container. This housing may for example be arranged at the edge upper side of the charging opening of the washing container on the washing compartment. When the Spülraumtür open the lighting device is in its use position in which it dominates the upper edge of the feed opening depending on the approved travel, so that in contrast to the prior art, a deeper illumination of the washing compartment is allowed. In this case, the housing or the illumination device is positioned on the rinsing container in such a way that, in the case of use, a co-operation of the rinsing chamber door with the illumination device can take place. It then requires no further switching devices, since an operation of the lighting device is automatically accompanied by a pivoting of the dishwasher door.

The illumination device can according to a further feature of the invention have a light source. Preferably, an LED is provided as the light source. To power a corresponding wiring can be provided or it is the formation of contact rails possible. The power supply is in any case designed such that the above-described movement of the lighting device from a non-use position is allowed in a use position and vice versa. Moreover, it is preferred to design the lighting device at least water-repellent, so that it can not be due to splashing water and / or vapors to damage the lighting device. However, a watertight embodiment of the lighting device is not necessary, since it is not arranged inside the washing compartment but outside it.

According to an alternative embodiment, the illumination device does not have a light source, but it is provided that a light guide opens into the illumination device. In this case, the light source is positioned independently of the illumination device and the light generated by it is conveyed by means of a light guide to the illumination device. The lighting device is thus formed at the end of the light guide.

With the invention, a dishwasher is proposed as a whole, which, in contrast to the prior art, permits improved illumination, in particular of the washing container, that is to say the washing compartment provided by the washing container. This is because the lighting device is designed to be movable and can be moved from a non-use position to a use position, in which position the relative position of the lighting device to the washing compartment is such that an illumination is made possible over an enlarged angular range in contrast to the prior art. As a result, shadowing caused by the charging port-side purge door seal is minimized.

Fig. 1 can be seen in a purely schematic representation of a dishwasher 1 according to the invention. This has, in a manner known per se, a housing 2 accommodating a washing container 3, which in turn defines a washing compartment 4. On the user side, the washing compartment 4 is accessible via a charging opening 5, which can be closed by means of a pivotally mounted flushing door 6. Fig. 1 shows the Spülraumtür 6 in the half-open position.

For illumination, in particular also of the washing compartment 4, the dishwasher 1 has a lighting device 7. Fig. 2 schematically identifies possible positions X for such a lighting device 7, wherein the use of multiple lighting devices 7 is possible.

The embodiment according to the other FIGS. 3 to 8 shows an embodiment according to which the dishwasher 1 has an illumination device 7, which is arranged in the region of the upper end edge of the feed opening 5. This factual context is in particular the case FIGS. 3, 4 and 5 recognize in their synopsis.

As can be seen in particular from the FIGS. 4 and 5 results, the lighting device 7 is arranged linearly movable on the washing container 3. For this purpose, a housing 11 is provided, in which the interposition of a spring 12, the lighting device 7 is housed. The illumination device 7 provides a contact surface 13 on the side of the flushing chamber, which interacts on the inside of the flushing chamber door 6 with a peripheral edge 10 of the flushing chamber door 6, as shown in FIGS FIGS. 4 and 5 reveal.

Fig. 4 shows the Spülraumtür 6 in the closed position. In this position, the Spülraumtür 6, the feed opening 5 is closed fluid-tight, which is achieved in that the Spülraumtür 6 rests with its inner side 9 to a circumferential door seal 8. The lighting device 7 is in this position of the Spülraumtür 6 in its non-use position and is turned off.

Now the Spülraumtür 6 is opened, which is in Fig. 5 is shown, it pivots with respect to the plane of the drawing Fig. 5 to the right, that is in the direction of the arrow. Due to the spring force acting on the illumination device 7, the illumination device 7 is moved linearly relative to the housing 11 and thus also relative to the rinsing container 3, in the direction of the arrow. In the extended position of the lighting device 7, as this in Fig. 5 is shown, selbige is in the use position and is turned on. In this position of use, an optimized illumination of the washing compartment 4 takes place by means of the lighting device 7 located in the position of use.

Fig. 6 shows the rinse tank 3 and the provided therefrom Spülraum 4 schematically in a side view with the Spülraumtür 6. According to detail B, the lighting device 7 is formed in the region of the upper peripheral edge of the feed opening 6.

Fig. 7 shows the detail B according to an embodiment of the prior art. According to this is an illumination device 7 with light distribution in the form of a lens used. As can be seen from this illustration, the possible angle of incidence α _{1 is} limited by the seal 8 on the flushing chamber side. It turns so far as a corresponding shading.

Fig. 8 shows the embodiment of the invention. As can be seen from this illustration, the angle of incidence α _2, in contrast to the prior art, increases considerably, namely because the illumination device 7 is illuminated from the non-use position for the purpose of illuminating the flushing space 4 Fig. 4 in the position of use Fig. 5 procedure is. The shading caused by the seal 8 is significantly reduced due to the increased light incidence angle α ₂ , which leads to the advantage of a significantly improved illumination of the washing compartment 4.

The FIGS. 9, 10 and 11 show an alternative embodiment. According to this embodiment, the illumination device 7 is not linearly movable, but designed to pivot about a fixed pivot point 14. However, the operation is the same as already explained with reference to the preceding figures, since the illumination device 7 from a non-use position ( Fig. 9 ) in a position of use ( Fig. 10 ) and vice versa. In this case, the illumination device 7 cooperates with the Spülraumtür 6, so that when opening the Spülraumtür 6 a transfer of the illumination device 7 takes place automatically in the use position. Even with a pivotable trained lighting device 7, this is preferably done by spring force. But an electromotive method of the illumination device 7 is of course conceivable, both in a movable and in a rotatable arrangement of the illumination device. 7
