Abstract

The invention relates to a cleaning device (1) with a cleaning lance (3) and a holding device (2) for housing the cleaning lance (3), said holding device containing a rechargeable electric energy storage device (9a) for providing electrical users of the cleaning lance (3) and a charging device (9b) for charging the energy storage device (9a). The invention solves the objective of providing the cleaning lance with electrical energy reliably and in a simple manner, in that the cleaning device (1) comprises an electrical energy transfer unit (11) for non-contact transferring of electrical energy between the holding device (2) and the charging device (9b) for charging the energy storage device (9a).

Claims

1. A cleaning device (1) with a cleaning lance (3) and a holding device (2) for storing the cleaning lance (3), wherein said cleaning device contains a rechargeable electrical energy storage device (9a) for supplying electrical consumers of the cleaning lance (3) and a charging device (9b) for charging the energy storage device (9a), wherein the cleaning device (1) features an electrical energy transfer unit (11) for the contactless transfer of electrical energy between the holding device (2) and the charging device (9b) in order to charge the energy storage device (9a).

2. The cleaning device (1) according to claim 1, wherein the energy transfer unit (11) consists of a transformer with a primary wire-wound coil (11a) arranged on the holding device (2) and a secondary wire-wound coil (11b) arranged on the cleaning lance (3).

3. The cleaning device (1) according to claim 1, wherein the holding device (2) features a tube for inserting an elongated jet tube (5) of the cleaning lance (3).

4. The cleaning device (1) according to claim 3, wherein the tube of the holding device (2) downwardly narrows in a conical fashion.

5. The cleaning device (1) according to claim 1, wherein a coupling device (14) holds the cleaning lance (3) inserted into the holding device (2) in a coupling position, in which a sufficient magnetic coupling for charging the energy storage device (11) exists between the holding device (2) and the charging device (9b).

6. The cleaning device (1) according to claim 5, wherein the primary wire-wound coil (11a) and the secondary wire-wound coil (11b) are arranged in close spatial vicinity of one another in the coupling position.

7. The cleaning device (1) according to claim 5, wherein the coupling device (14) contains the primary wire-wound coil (11a) and/or the secondary wire-wound coil (11b).

8. The cleaning device (1) according to claim 4, wherein the coupling device (14) features a first stop on the holding device (2) and a second stop (16;

18;

20;

22) on the cleaning lance (3), and by the fact that the stops (16, 17;

18, 19;

20, 21;

22, 23) hold the cleaning lance (3) in the coupling position in the holding device (2).

9. The cleaning device (1) according to claim 8, wherein the first stop (19;

21) is formed by the primary wire-wound coil (11a) and/or the second stop (20;

22) is formed by the secondary wire-wound coil (11b).

10. The cleaning device (1) according to claim 9, wherein the first stop (15;

19) and the second stop (16;

20) are realized in the shape of a circular ring, wherein the inside diameter of the first stop (15;

19) is smaller than the outside diameter of the second stop (16;

20).

11. The cleaning device (1) according to claim 9, wherein the first stop is realized in the form of an internal cone segment (17;

21) that narrows in the inserting direction (E) of the cleaning lance (3) and the second stop is realized in the form of an external cone segment (18;

22) that is tapered in the inserting direction (E), wherein the larger diameter of the external cone segment (18;

22) is larger than the smaller diameter of the internal cone segment (17;

21).

12. The cleaning device (1) according to claim 1, wherein an insertion aid (17, 18;

21, 22) is provided for inserting the cleaning lance (3) into the coupling position in the holding device (2).
