Abstract

A household dishwasher includes a rinsing container, a washing item receptacle, a guide mechanism for moving the washing item receptacle from a starting state within the rinsing container to an end state outside the rinsing container and vice versa, and a lifting mechanism for raising the washing item receptacle from a starting position to an end position and to lower it from the end position to the starting position. The lifting mechanism includes a lifting lever pivotably connected to the rinsing container and the guide mechanism and having a guide contour for arresting the washing item receptacle in the end position when lifted from the starting position to the end position and in the end state when lowered from the end position to the starting position so that the washing item receptacle is only movable from the starting state to the end state in the starting position and vice versa.

First claim

1 - 15 . (canceled)

16 . A household dishwasher, comprising:
a rinsing container; a washing item receptacle for receiving an item to be washed; a guide mechanism configured to move the washing item receptacle from a starting state arranged within the rinsing container to an end state arranged outside of the rinsing container and vice versa; and a lifting mechanism configured to raise the washing item receptacle from a starting position to an end position and to lower the washing item receptacle from the end position to the starting position, said lifting mechanism comprising a lifting lever connected in a pivotable manner to the rinsing container and the guide mechanism and having a guide contour configured to arrest the washing item receptacle in the end position when the washing item receptacle is lifted from the starting position to the end position and to arrest the washing item receptacle in the end state when the washing item receptacle is lowered from the end position to the starting position so that the washing item receptacle is only movable from the starting state to the end state in the starting position and vice versa.

17 . The household dishwasher of claim 16 , wherein the guide contour is configured to guide the washing item receptacle when the washing item receptacle is raised from the starting position to the end position and when the washing item receptacle is lowered from the end position to the starting position such that a spacing between the rinsing container and the washing item receptacle is uniform.

18 . The household dishwasher of claim 16 , wherein the guide contour defines a maximum withdrawal path of the washing item receptacle when the washing item receptacle is moved from the starting state to the end state.

19 . The household dishwasher of claim 16 , wherein the guide contour has a first guide portion and a second guide portion connected to the first guide portion, said second guide portion being inclined at an angle of inclination relative to the first guide portion.

20 . The household dishwasher of claim 19 , wherein the first guide portion is straight and the second guide portion is straight or curved.

21 . The household dishwasher of claim 19 , wherein the first guide portion in the starting position is arranged parallel to the guide mechanism and in the end position is arranged perpendicular to the guide mechanism.

22 . The household dishwasher of claim 19 , wherein the second guide portion is arranged in the starting position and in the end position at an incline relative to the guide mechanism, wherein in the starting position the second guide portion is inclined by 90° relative to an orientation in the end position.

23 . The household dishwasher of claim 16 , wherein the guide contour has a first guide portion, a second guide portion connected to the first guide portion, a third guide portion connected to the second guide portion, and a fourth guide portion connected to the third guide portion.

24 . The household dishwasher of claim 23 , wherein the first, second, third and fourth guide portions are configured to form a U-shaped or approximately U-shaped guide contour.

25 . The household dishwasher of claim 16 , wherein the washing item receptacle includes a guide pin which is guided in the guide contour when the washing item receptacle is raised from the starting position to the end position and when the washing item receptacle is lowered from the end position to the starting position.

26 . The household dishwasher of claim 25 , wherein in the starting state the guide pin is out of engagement with the guide contour, and wherein the guide pin is brought into positive engagement with the guide contour when the washing item receptacle is moved from the starting state to the end state.

27 . The household dishwasher of claim 26 , wherein the guide contour has a lead-in chamfer for inserting the guide pin into the guide contour when the washing item receptacle is moved from the starting state to the end state.

28 . The household dishwasher of claim 16 , wherein the guide contour has a first guide portion, a second guide portion connected to the first guide portion, and a latching geometry between the first guide portion and the second guide portion.

29 . The household dishwasher of claim 28 , wherein the latching geometry is a latching lug.

30 . The household dishwasher of claim 25 , further comprising a spring-loaded latching bolt which cooperates with the guide pin and is brought into engagement outside the guide contour.

31 . The household dishwasher of claim 25 , further comprising a spring element supported against the guide contour and acting on the guide pin.

32 . The household dishwasher of claim 16 , wherein the lifting mechanism comprises a first lifting lever configured to include the guide contour and a second lifting lever arranged in spaced apart relation to the first lifting lever and pivotably connected to the rinsing container and the guide mechanism.

33 . The household dishwasher of claim 32 , further comprising a further guide mechanism, with one of the first and second lifting levers being pivotably connected to one of the guide mechanisms and the other one of the first and second lifting levers being pivotably connected to the other one of the guide mechanisms.
