Abstract

An adding device for dishwashers includes a fillable supply chamber for receiving a tablet-type detergent or rinsing agent. The supply chamber is arranged and configured in such a way that, when the adding device is in an operational position in the dishwasher, the detergent or rinsing agent can escape from the supply chamber into the rinsing area in a non-impeded manner in the direction of gravity. As a result, no substantial detergent residues remain in the supply chamber after the cleaning or rinsing program has come to an end. This results in the addition of cleaner into the dishwasher in an improved, reliable manner.

Claims (17)

1. An adding device for adding into a dishwasher an agent that assists an operation of the dishwasher, the adding device comprising:

a supply chamber for receiving an agent that assists an operation of a dishwasher, the supply chamber permitting an agent received therein to exit from the supply chamber and thereafter enter a wash area in which items to be handled by the dishwasher are disposed, and the adding device being disposable between a filling disposition in which a fill quantity of an agent can be filled into the supply chamber, with the fill quantity of the agent being that quantity of the agent that comprises a complete number of doses of the agent to be administered during a respective dishwasher operation, and an operating disposition in which no structure prevents substantially the fill quantity of the agent from exiting the supply chamber in a full release manner with none of the agent being subjected to any intervening stoppages as the agent exits the supply chamber, the agent that has been released from the supply chamber having a direction of movement once it is beyond the supply chamber in the direction of gravity.

2. The adding device as claimed in claim 1 wherein the supply chamber is mounted at a selected one of in a door of the dishwasher and on a door of the dishwasher, the door of the dishwasher closing off the wash area from outside.

3. The adding device as claimed in claim 2 , wherein, in the operating disposition of the adding device, a plane along which a door inner-side opening of the supply chamber runs, is inclined in the direction of the wash area.

4. The adding device as claimed in claim 3 , wherein the plane along which the door inner-side opening of the supply chamber runs forms an obtuse angle with the direction of gravity.

5. The adding device as claimed in claim 2 , wherein the supply chamber is arranged in a transition of the door inner side between a control panel area arranged in the door and another area of the door.

6. The adding device as claimed in claim 2 , wherein the supply chamber is arranged such that, when the door is open and the wash basket of the dishwasher is pulled out completely so that it can be filled, the supply chamber is not covered in any manner by the wash basket in the direction of filling of the supply chamber.

7. The adding device as claimed in claim 1 wherein the adding device is geometrically formed and arranged so that, in the operating disposition of the adding device, free access from an upper supply chamber inner wall into the wash area in the direction of gravity is possible.

8. The adding device as claimed in claim 1 wherein the adding device is geometrically formed and arranged so that the detergent or rinsing agent, as a result of its gravitational force, falls in a straight line and unimpeded into the wash area.

9. The adding device as claimed in claim 1 , wherein the adding device is geometrically formed and arranged so that, in the operating disposition of the supply chamber, a hollow is formed for accommodating the detergent or rinsing agent.

10. The adding device as claimed in claim 1 , wherein the supply chamber is able to be closed by a cover.

11. The adding device as claimed in claim 10 , wherein the cover is embodied and arranged so as to be able to be moved along the inner side of a door of the dishwasher which closes off the wash area from the outside.

12. A dishwasher, comprising:

a wash area in which items to be handled by the dishwasher are disposed; and

an adding device for adding into the dishwasher an agent that assists an operation of the dishwasher, the adding device including a supply chamber for receiving an agent that assists an operation of a dishwasher, the supply chamber permitting an agent received therein to exit from the supply chamber and thereafter enter the wash area in which items to be handled by the dishwasher are disposed, and the adding device being disposable between a filling disposition in which a fill quantity of an agent can be filled into the supply chamber, with the fill quantity of the agent being that quantity of the agent that comprises a complete number of doses of the agent to be administered during a respective dishwasher operation, and an operating disposition in which no structure prevents substantially the fill quantity of the agent from exiting the supply chamber in a full release manner with none of the agent being subjected to any intervening stoppages as the agent exits the supply chamber, the agent that has been released from the supply chamber having a direction of movement once it is beyond the supply chamber in the direction of gravity.

13. The dishwasher as claimed in claim 12 , wherein the supply chamber is mounted at a selected one of in a door of the dishwasher and on a door of the dishwasher, the door of the dishwasher closing off the wash area from outside, the dishwasher includes a wash basket of the dishwasher that can be moved out of the wash area to fill it, the supply chamber of the adding device is arranged such that, when the door is in an opened state and with the wash basket fully moved-out, the supply chamber is not covered in any manner by the wash basket in the direction of filling of the supply chamber.

14. The dishwasher as claimed in claim 12 , wherein the supply chamber is mounted at a selected one of in a door of the dishwasher and on a door of the dishwasher, the door of the dishwasher closing off the wash area from outside, the dishwasher includes a wash basket of the dishwasher that can be moved out of the wash area to fill it, the supply chamber of the adding device is arranged such that, when the door is in an opened state and with the wash basket fully moved-out, the supply chamber is not partly covered by the wash basket in the direction of filling of the supply chamber.
