Abstract

An automatically controlled washing machine has a machine body and a dispensing mechanism which is arranged in the machine body and intended to dispense powdered, liquid or gel-form laundry treatment media. The dispensing mechanism includes a drawer which is accessible from a front of the machine body via a front handle. The drawer has a guide frame which is connected to the front handle and has at least one window-like recess for insertion of at least one container which accepts laundry treatment media and is connectable to the guide frame. A device automatically feeds laundry treatment medium from the container into a treatment process.

Claims

1. An automatically controlled washing machine, comprising:

a machine body;

a dispensing mechanism, arranged in the machine body to dispense powdered, liquid or gel-form laundry treatment media, said dispensing mechanism including a drawer with no bottom floor surface and at least one container having a bottom to hold the laundry treatment media, the drawer being accessible from a front of the machine body via a front handle and has a guide frame connected to the front handle and provided with at least one window-like recess forming a through-opening in the guide frame such that the guide frame has an open bottom, the guide frame including an edge at a perimeter of the through-opening, the through-opening being structured and dimensioned for insertion therethrough of the at least one container such that the container is suspended into the through-opening from the edge of the guide frame and at least a portion of the at least one container'"'"'s weight is supported by the edge of the guide frame; and

a device to automatically feed laundry treatment medium from the container into a treatment process.

2. The washing machine of claim 1, wherein the container is provided for a supply, comprising a single dose, of liquid or powdered laundry treatment medium.

3. The washing machine of claim 1, wherein the container is provided for a supply comprising a plurality of doses of liquid or gel-form laundry treatment media.

4. The washing machine of claim 3, wherein the container is a marketable cartridge which is filled with a supply of liquid or gel-form laundry treatment media.

5. The washing machine of claim 1, wherein the guide frame is supported in angularly stable relationship to the handle, said edge being bounded by a downwardly directed flange.

6. The washing machine of claim 5, wherein the container has an interrupted or encircling collar which is supported on the edge of the guide frame as the container is inserted through the recess.

7. The washing machine of claim 6, wherein an undersurface of the collar is supported on the edge of the guide frame.

8. The washing machine of claim 1, wherein the guide frame comprises a material with a thickness and the through-opening is formed through the thickness.

9. The washing machine of claim 1, wherein substantially all of the container'"'"'s weight is supported by the edge of the guide frame.

10. The washing machine of claim 1, wherein the at least one container is supported only by the edge of the guide frame.

11. The washing machine of claim 1, wherein the guide frame has lateral edges configured to be slidably guided by guide rails of the dispensing mechanism, and the drawer has an open bottom such that no bottom wall is connected to the lateral edges of the guide frame.

12. The washing machine of claim 1, wherein the dispensing mechanism is configured to flush the laundry treatment medium out of the at least one container directly onto a bottom of a housing shell of the dispensing mechanism.

13. The washing machine of claim 1, wherein the at least one window-like recess is a plurality of window-like recesses and the at least one container is a plurality of containers such that each window-like recess has a through-opening for insertion therethrough of a respective container.

14. The washing machine of claim 13, wherein at least two of the plurality of window-like recesses have different sizes and different shapes.

15. The washing machine of claim 13, wherein at least one of the containers has an open top and at least another one of the containers has a closed form except for a refill opening.

16. The washing machine of claim 13, wherein the guide frame is supported in angularly stable relationship to the handle, each of said plurality of window-like recesses having a respective edge at a perimeter thereof, and

wherein each of the plurality of containers has an interrupted or encircling collar which is supported on a corresponding edge of the plurality of window-like recesses.

17. The washing machine of claim 13, wherein at least one of the containers is provided for a supply, comprising a single dose, of liquid or powdered laundry treatment medium.

18. The washing machine of claim 13, wherein at least one of the containers is provided for a supply comprising a plurality of doses of liquid or gel-form laundry treatment media.

19. The washing machine of claim 18, wherein the at least one container is a marketable cartridge which is filled with a supply of liquid or gel-form laundry treatment media.

20. The washing machine of claim 13, wherein the guide frame is supported in angularly stable relationship to the handle, the edge corresponding to at least one of the recesses being bounded by a downwardly directed flange.

21. The washing machine of claim 20, wherein at least one of the containers has an interrupted or encircling collar which is supported on the edge corresponding to the at least one recess as the container is inserted through the recess.

22. The washing machine of claim 21, wherein an undersurface of the collar is supported on the edge corresponding to the at least one recess.

23. The washing machine of claim 13, wherein at least one of the containers has a lateral outlet to discharge laundry treatment media from the container.

24. The washing machine of claim 13, wherein each of said plurality of window-like recesses has a respective edge at a perimeter thereof, and

wherein each of the plurality of containers has an interrupted or encircling collar which is supported on a corresponding edge of the plurality of window-like recesses, and

wherein each edge of the plurality of window-like recesses extends an entire perimeter of a respective through-opening, the collar of a respective one of the plurality of containers being supported along the entire edge of the respective window-like recess.

25. The washing machine of claim 13, wherein at least one of the containers has a lateral outlet to discharge laundry treatment media from the container, and at least another one of the containers has a siphon device to discharge laundry treatment media from the another container, and

wherein the container having the lateral outlet and the another container having the siphon device are interchangeably received in the same through-opening.
