Abstract

The present invention relates to a vacuum cleaner, comprising a carrier part, a liquid container, and a suction head. A bracket is pivotably fastened to the liquid container, so that the bracket can be used as a positioning element for the suction head. The suction head can be fixed in a parking position that is tilted by an angle (γ) greater than 0° from the top edge of the container, in that the suction head lies on the bracket. The bracket is latched to the container in the parking position.

Claims

1. A vacuum cleaner, comprising:

a liquid container having an interior space which is adapted for being filled at least partially with liquid; and

a suction head, which is arranged in a first position, relative to the liquid container, such that the suction head can be removed from the liquid container,

wherein the vacuum cleaner has a positioning element, which can be adjusted such that the suction head can be arranged in a second position relative to the liquid container, wherein the suction head, in the second position relative to the first position, is inclined at a first angle (γ

) angle wherein the first angle (γ

) lies between about 3° and

about 15°

, and wherein the liquid container has a connecting element and a channel having a channel end arranged in the liquid of the interior space, and air flows through an opening in the connecting element and into the interior space of the liquid container via the channel and is guided in the liquid in order to bind dirt and dust.

2. The vacuum cleaner in accordance with claim 1, wherein the positioning element is configured as a bracket.

3. The vacuum cleaner in accordance with claim 2, wherein the positioning element is pivotably arranged at the liquid container.

4. The vacuum cleaner in accordance with claim 3, wherein the positioning element has at least a first setting position, which corresponds to the first position of the suction head, and a second setting position, which corresponds to the second position of the suction head.

5. The vacuum cleaner in accordance with claim 4, wherein the positioning element can be arrested in the first setting position and/or in the second setting position by an arresting mechanism.

6. The vacuum cleaner in accordance with claim 5, wherein the positioning element has a third setting position in which the positioning element can serve as a handle for transporting the liquid container.

7. The vacuum cleaner in accordance with claim 6, wherein the positioning element has an edge which faces the suction head and which, in the first position, is arranged parallel and/or flush with a top edge of a wall bounding an upper opening of the liquid container.

8. The vacuum cleaner in accordance with claim 7, wherein the edge which faces the suction head, in the second position, is inclined at a second angle (β

) greater than 0°

relative to the top edge of the wall bounding the upper opening of the liquid container.

9. The vacuum cleaner in accordance with claim 8, wherein the second angle (β

) lies between about 5° and

about 20°

.

10. The vacuum cleaner in accordance with claim 1, wherein the suction head is adapted to allow the suction head to rest stably on a planar surface.

11. The vacuum cleaner in accordance with claim 1, wherein the vacuum cleaner has a carrier part for allowing the liquid container to lie on the carrier part.

12. The vacuum cleaner in accordance with claim 11, wherein the carrier part has a recess, whose cross-section corresponds to a cross-section of a bottom surface of the liquid container.

13. The vacuum cleaner in accordance with claim 12, wherein the carrier part has rollers adapted for allowing the carrier part to lie movably on a substrate.

14. The vacuum cleaner in accordance with claim 11, wherein the carrier part has rollers adapted for allowing the carrier part to lie movably on a substrate.

15. The vacuum cleaner in accordance with claim 1, wherein the positioning element is configured as a bracket.

16. The vacuum cleaner in accordance with claim 1, wherein the positioning element is pivotably arranged at the liquid container.

17. The vacuum cleaner in accordance with claim 1, wherein the positioning element has at least a first setting position, which corresponds to the first position of the suction head, and a second setting position, which corresponds to the second position of the suction head.

18. The vacuum cleaner in accordance with claim 17, wherein the positioning element has a third setting position in which the positioning element is adapted as a handle for transporting the liquid container.

19. The vacuum cleaner in accordance with claim 1, wherein the liquid container includes a side wall and a bottom wall that bound the interior space, the bottom wall being disposed in a bottom half of the liquid container, further wherein the channel end extends in the interior space into the bottom half of the liquid container.

20. A vacuum cleaner, comprising:

a liquid container having an interior space which is adapted for being filled at least partially with liquid; and

a suction head, which is arranged in a first position, relative to the liquid container, such that the suction head can be removed from the liquid container,

wherein the vacuum cleaner has a positioning element, which can be adjusted such that the suction head can be arranged in a second position relative to the liquid container, wherein the suction head, in the second position relative to the first position, is inclined at a first angle (γ

) angle greater than 0°

, wherein the positioning element stays in its position under the weight of the suction head resting on it when the suction head is in the second position relative to the liquid container, and wherein the liquid container has a connecting element and a channel having a channel end arranged in the liquid of the interior space, and air flows through an opening in the connecting element and into the interior space of the liquid container via the channel and is guided in the liquid in order to bind dirt and dust.
