Abstract

A dishwasher includes a dishwashing compartment having a loading opening which can be closed by a door configured. At least one washware basket is provided for movement out of and into the dishwashing compartment, with at least one movement position of the washware basket being recognized by a device. At least one light source is arranged in or on the dishwasher and controlled by a control device in dependence on the at least one movement position of the washware basket.

First claim

The invention claimed is:

1. A dishwasher, comprising:
a dishwashing compartment having a loading opening;
a door configured to close the loading opening;
at least one washware basket configured for movement out of and into the dishwashing compartment;
a device configured for recognition of at least one movement position of the at least one washware basket;
at least one light source arranged in or on the dishwasher; and
a control device configured to control the at least one light source in dependence on the at least one movement position of the at least one washware basket,
wherein the at least one light source has an elongated configuration or the dishwasher comprises a multiplicity of said at least one light source arranged in a row, said control device being configured to activate the at least one light source of elongated configuration or the row of light sources, such that a change of a parameter of the at least one light source of elongated configuration or of the row of light sources propagates in a direction of movement of at least one washable basket.

2. The dishwasher of claim 1 , constructed in the form of a domestic dishwasher.

3. The dishwasher of claim 1 , wherein the loading opening is a frontal loading opening.

4. The dishwasher of claim 1 , wherein the device is configured for non-contacting operation.

5. The dishwasher of claim 1 , wherein the at least one light source is provided in the dishwashing compartment at a location outside the at least one washware basket.

6. The dishwasher of claim 1 , wherein the dishwashing compartment has a floor and side walls, said at least one light source being provided in one of three ways, a first way in which the at least one light source is provided in or on the floor, a second way in which the at least one light source is provided in or on the side walls, a third way in which the at least one light source is provided in or on an internal wall surface of the door in confronting relation to an interior of the dishwashing compartment, when the door is in a final closure position.

7. The dishwasher of claim 1 , wherein the parameter is a member selected from the group consisting of illuminance, color, mode of illumination, time of activation, time of deactivation, and timing.

8. The dishwasher of claim 1 , wherein said light source of elongated configuration or said multiplicity of said at least one light source is arranged along a guide track provided for the at least one washware basket in the dishwashing compartment or on an internal wall surface of the door.

9. The dishwasher of claim 8 , further comprising a multiplicity of said at least one washware basket to define a lower washware basket, said guide track being provided for the lower washware basket.

10. The dishwasher of claim 8 , wherein the guide track has a runner surface, on which the at least one washware basket rests in slidable form.

11. The dishwasher of claim 1 , wherein on condition that said at least one light source comprises the multiplicity of said at least one light source, said control device being configured to activate a different number of light sources depending on a path of travel of the at least one washware basket.

12. The dishwasher of claim 11 , wherein the control device activates an increasing number of said light sources as the path of travel of the at least one washware basket increases.

13. The dishwasher of claim 11 , wherein the control device activates the light sources in such a way that a number of illuminated ones of the light sources increases in an extension direction of the at least one washware basket and decreases in a retraction direction.

14. The dishwasher of claim 11 , wherein the multiplicity of light sources are arranged in a row extending in a direction of movement of the at least one washware basket in or on an internal wall surface of the door or of a wall of the dishwashing compartment.

15. The dishwasher of claim 14 , wherein the wall is formed by a floor of the dishwashing compartment or a side wall of the dishwashing compartment.

16. The dishwasher of claim 14 , wherein the row of light sources is arranged in immediate vicinity of or directly along a guide track, along which the at least one washware basket is guided in an extendable or retractable manner.

17. The dishwasher of claim 16 , wherein the guide track has a runner surface, on which the at least one washware basket rests in slidable form, said row of light sources being arranged in immediate vicinity of or directly on the runner surface.

18. The dishwasher of claim 1 , wherein a length of the at least one light source of elongated configuration or a length of the row of light sources corresponds to a maximum distance of travel of the at least one washware basket.

19. The dishwasher of claim 1 , wherein the at least one light source of elongated configuration or the row of light sources is activated such that the parameter propagates at a speed corresponding to a speed of travel of the at least one washware basket.

20. The dishwasher of claim 1 , wherein the at least one light source is provided on an inner face of a side wall or of a floor of the dishwashing compartment or on an inner face of an inner wall of the door which faces an interior of the dishwashing compartment when the door is in the closed position.

21. The dishwasher of claim 1 , wherein the dishwashing compartment has a side wall and a floor, said at least one light source being arranged in an opening of the side wall, or in an opening of the floor, or in an opening of an inner wall of the door.

22. The dishwasher of claim 1 , wherein the door has a recess which accommodates the at least one light source and is covered by a translucent inner wall of the door or by a translucent partial area of an inner wall of the door.

23. The dishwasher of claim 22 , wherein the inner wall of the door or the partial area is provided with a coating, leaving free a window arranged above the at least one light source, said coating having a translucency which is lower than a translucency of a material forming the translucent inner wall of the door or the translucent partial area.
