Abstract

The invention relates to an arrangement having a washing-machine tub and a drive motor, which can be connected to the tub by a suspension device, wherein the suspension device is designed as a two-point attachment means, wherein a housing of the drive motor has arranged on it two rockers designed for connection in each case to a rocker mount arranged on the tub. The invention also relates to a washing machine having such an arrangement.

First claim

The invention claimed is:

1. A washing machine system comprising a tub and a drive motor connected to the tub using a suspension device, wherein the suspension device is connected to the tub at two connection points only, wherein two links are connected to tub-side link mounts disposed on a housing of the drive motor, wherein the links, with respect to the direction of an axis of a shaft of the drive motor, are disposed at the level of a ball bearing of the drive motor such that the links and the ball bearing are all within a plane perpendicular to the axis to minimize forces acting on the connection points due to weight distribution when the drive motor is in motion.

2. The washing machine system as claimed in claim 1 , wherein the links are disposed at an angle with respect to a bisector of the drive motor which is perpendicular to the axis.

3. The washing machine system of claim 2 , wherein the links are disposed at an angle between 30° and 60° with respect to the bisector of the drive motor.

4. The washing machine system as claimed in claim 1 , wherein an axis (A) of a shaft of the drive motor and axes of the links mounts are not disposed coaxially.

5. The washing machine system as claimed in claim 4 , wherein an axis of the shaft and the axes of the link mounts are oriented parallel to one another.

6. The washing machine system as claimed in claim 1 , wherein a straight line connecting axes of the link mounts is perpendicular to the axis of a shaft of the drive motor with respect to a view normal to the axis of the shaft of the drive motor.

7. The washing machine system as claimed in claim 1 , wherein the link mounts are plastic sleeves.

8. The washing machine system as claimed in claim 1 , wherein the tub is fiber glass reinforced or made of duroplastic material at least in a region of the link mounts.

9. The washing machine system as claimed in claim 1 , wherein the drive motor is a BLDC motor.

10. The washing machine system as claimed in claim 1 , wherein the drive motor is screwed to the tub.

11. A washing machine comprising the washing machine system as claimed in claim 1 .

12. The washing machine system of claim 1 , wherein, with respect to the direction of the axis of the shaft of the drive motor, a longitudinal center line of the links is disposed substantially aligned with a longitudinal center line of the ball bearing.

13. The washing machine system of claim 1 , wherein, with respect to the direction of the axis of the shaft of the drive motor, a longitudinal center line of the link mounts is disposed substantially aligned with a longitudinal center line of the ball bearing.

14. The washing machine system of claim 1 , wherein, with respect to the direction of the axis of the shaft of the drive motor, a longitudinal center line of both the links and the links mounts is disposed substantially aligned with a longitudinal center line of the ball bearing.

15. The washing machine system of claim 1 , wherein the links and the ball bearing are aligned in the plane perpendicular to the axis.
