Embodiment Construction

[0049] Figures 1A to 1C A household appliance generally provided with reference numeral 10 is shown. The household appliance 10 may be a piece of furniture such as a dishwasher, oven, refrigerator, microwave, steam cooker, dryer, freezer, or furniture such as a cabinet or table, just to name a few. The household appliance 10 has a body or housing 12 and a door 14 . exist Figure 1A In , the door 14 is shown in its closed position. Door 14 may be held in the closed position by a lock (not shown). The lock can be a so-called pull-off lock or pull-off lock, which holds the door 14 in the closed position by means of a non-positive fit. By applying a pulling force, the door can move from its closed position to its open position. At the beginning of the opening process, a slightly higher pulling force is required to open the door in order to overcome the force lock when the door 14 remains in the closed position.

[0050] The domestic appliance 10 also has a device 20 for auto...

Abstract

The invention relates to a device for automatically opening a door of a household appliance, the device comprising a tappet and a motor, which is operatively connected to the tappet, such that the tappet is moved in the direction of the longitudinal axis of the tappet from a retracted position into an extended position, and the door is moved from a closed position into a partially open position, and the device also comprising an overload protection mechanism. The tappet has a shaft aligned with the tappet at a rearward advancing end in the extension direction, the shaft being held in threaded engagement with a drive wheel, the drive wheel being rotatable by means of a motor to move the tappet in the axial direction. The overload protection mechanism has a bushing through which the tappet penetrates, the tappet and the bushing are non-rotatable relative to one another about a longitudinal axis of the tappet, the tappet can be moved in the direction of the longitudinal axis relative to the bushing, a rotation of the bushing about the longitudinal axis of the tappet is locked when the extension movement of the tappet is not blocked or prevented or when no force acts on the tappet in the retraction direction of the tappet, and the bushing is locked when the extension movement of the tappet is blocked or prevented. Or when a force acts axially on the tappet in the retraction direction of the tappet, the bushing rotates together with the tappet about the longitudinal axis of the tappet.
