Abstract

A refrigeration appliance has an ice and water dispenser with a container receptacle. The refrigeration appliance has a light projector for projecting information into the container receptacle. A method serves to operate a refrigeration appliance, in which information is projected into a container receptacle of an ice and water dispenser by a light projector.

First claim

The invention claimed is:

1. A refrigeration appliance, comprising:
an ice and water dispenser having a container receptacle;
a light projector for projecting information into said container receptacle; and
a lever switch projecting into said container receptacle and said light projector projecting the information onto said lever switch.

2. The refrigeration appliance according to claim 1 , wherein said light projector projects light from a ceiling side into said container receptacle.

3. The refrigeration appliance according to claim 1 , wherein said light projector is a laser projector.

4. The refrigeration appliance according to claim 1 , wherein said container receptacle has a side wall and said light projector projects the information onto said side wall of said container receptacle.

5. The refrigeration appliance according to claim 1 , wherein said lever switch has a plate-shaped operating area and said light projector projects the information onto a face of said plate-shaped operating area.

6. The refrigeration appliance according to claim 1 , wherein said container receptacle has a base and said light projector projects the information onto said base of said container receptacle.

7. A refrigeration appliance, comprising:
an ice and water dispenser having a container receptacle;
a light projector for projecting information into said container receptacle; and
a presence detector operating in a contact-free manner for detecting a position of objects in said container receptacle and set up to recognize a presence of the object in a vicinity of projected selection information as an actuation of the projected selection information using said presence detector and set up to carry out an action adapted to actuated selection information upon recognition of an actuation.

8. The refrigeration appliance according to claim 7 , wherein the refrigeration appliance is set up to project a plurality of the projected selection information adjacent to one another into said container receptacle by means of said light projector.

9. The refrigeration appliance according to claim 7 , wherein the projected selection information contains various output modes.

10. The refrigeration appliance according to claim 7 , wherein:
said container receptacle has a base and said light projector projects the projected selection information onto said base of said container receptacle; and
said light projector is set up to project at least one item of target information onto said base of said container receptacle.

11. The refrigeration appliance according to claim 10 , wherein said container receptacle has a top and at said top at least one output opening is formed therein and projects into said container receptacle and the target information can be projected by means of said light projector onto said base of said container receptacle below said at least one output opening.

12. The refrigeration appliance according to claim 7 , wherein the refrigeration appliance:
has different output openings formed therein which are disposed adjacent to one another for several output modes; and
is set up to project an item of target information, adapted to an actuated output mode, into said container receptacle by means of said light projector upon recognition of an actuation of an output mode.
