Abstract

A cleaning apparatus for cleaning floors and/or surfaces, having a container for holding a cleaning fluid, a discharge device for discharging the cleaning fluid onto a floor and/or surface to be cleaned, and a heating device for heating and/or tempering and/or evaporating the cleaning fluid. The cleaning apparatus can easily be supplied with energy for heating and/or tempering and/or evaporating the cleaning fluid, and the apparatus can be operated cordlessly.

First claim

The invention claimed is:

1. A cleaning apparatus configured to clean a floor, surface, or both, the apparatus comprising:
a container configured to hold a cleaning fluid;
a discharge device configured to discharge the cleaning fluid onto a floor, a surface, or a floor and a surface to be cleaned; and
a heating device configured for heating, temperature control, vaporization, or a combination thereof, of the cleaning fluid,
wherein the heating device includes a heating element and a heat store, the heat store being distinct from the cleaning fluid and being configured to heat the cleaning fluid,
wherein the heating device is configured to be coupled to an external power source for charging the heating device during a charging period,
wherein the heating element is configured to generate heat during the charging period, thereby heating the heat store,
wherein the heating device is configured to be decoupled from the external power source during a cleaning process such that the cleaning apparatus operates cordlessly during the cleaning process,
wherein the heat store is configured to keep the cleaning fluid at a predefinable operating temperature during the cleaning process.

2. The apparatus of claim 1 , wherein the heat store includes sugar.

3. The apparatus of claim 1 , wherein the heating device is configured to heat the cleaning fluid to an operating temperature that is greater than 10° C., but below 100° C.

4. The apparatus of claim 1 , wherein the heating device is configured to heat the cleaning fluid to an operating temperature that is greater than 100° C.

5. The apparatus of claim 1 , wherein the heating element comprises an electrical resistance heater.

6. The apparatus of claim 1 , wherein the heating device is configured to switch off automatically once a predefined operating temperature of the cleaning fluid has been reached.

7. The apparatus of claim 1 , wherein at least one of the heating device and the heat store is configured to operate cordlessly.

8. The apparatus of claim 1 , wherein the heating device can is configured to be operated by a battery.

9. The apparatus of claim 8 , wherein the battery is configured to be charged by a charging apparatus which is held either in or on the cleaning apparatus, in or on an external charging station, or both.

10. The apparatus of claim 9 , wherein at least two of the charging apparatus, the heating device, the heat store, and the cleaning fluid are configured to be acted on simultaneously with energy.

11. The apparatus of claim 1 , wherein the heating device is configured to be operated by a mains voltage.

12. The apparatus of claim 1 , wherein the heating device is configured to be operated by liquid fuel, solid fuel, gaseous fuel, or a mixture of two or more of any of these.

13. The apparatus of claim 1 , wherein the heat store includes a phase change material.

14. The apparatus of claim 1 , wherein the heat store comprises aluminum or tin.

15. The apparatus of claim 1 , wherein the heat store is surrounded at least in part by the container.

16. The apparatus of claim 1 , wherein the heat store is in contact with the container.

17. The apparatus of claim 1 , wherein the container is configured to be removed from the cleaning apparatus.

18. The apparatus of claim 1 , wherein at least one of the heating device and the heat store is removable from the apparatus.

19. The apparatus of claim 1 , wherein at least one of the heating device and the heat store is integrated into the container.

20. The apparatus of claim 1 , configured to be separable from a charging station.

21. The apparatus of claim 1 , wherein the discharge device is insulated with respect to the surrounding environment.

22. The apparatus of claim 1 , wherein the discharge device is heated.

23. The apparatus of claim 1 , wherein the discharge device is mechanically operable, pneumatically operable, hydraulically operable, electrically operable, or two or more of these.

24. The apparatus of claim 1 , wherein the container is-comprises a thermally insulated fluid tank.

25. The apparatus of claim 1 , further comprising:
a frame including an opening provided in the frame,
wherein the discharge device is configured to apply cleaning fluid to the floor, surface, or both, to be cleaned through the opening.

26. The apparatus of claim 25 , further comprising:
a cloth including a planar main body, in which a hole is formed.

27. The apparatus of claim 1 , further comprising:
a display device,
wherein the display device is configured to indicate that an operating temperature of the cleaning fluid has been reached.

28. The apparatus of claim 27 , wherein the display device comprises a whistle.

29. The apparatus of claim 28 , wherein the whistle is arranged in the vicinity of the discharge device.

30. The apparatus of claim 1 , further comprising:
a fill level indicator,
wherein the fill level indicator is configured to indicate a quantity of cleaning fluid still available.

31. The apparatus of claim 1 , further comprising:
a reheater element,
wherein the reheater element is assigned to the heating device or the discharge device so as to vaporize the cleaning fluid.

32. The apparatus of claim 1 , further comprising:
a metering device,
wherein the metering device is configured to add a substance to the cleaning fluid.

33. The apparatus of claim 1 , configured as a mop.

34. The apparatus of claim 1 , wherein the heat store includes steel or zinc.

35. A cleaning apparatus configured to clean a floor, surface, or both, the apparatus comprising:
a container configured to hold a cleaning fluid;
a discharge device configured to discharge the cleaning fluid onto a floor, a surface, or a floor and a surface to be cleaned;
a heating device configured for heating, temperature control, vaporization, or a combination thereof, of the cleaning fluid; and
a display device,
wherein the heating device includes a heating element and a heat store,
wherein the heating device is configured to be coupled to an external power source for charging the heating device during a charging period,
wherein the heating element is configured to generate heat during the charging period, thereby heating the heat store,
wherein the heating device is configured to be decoupled from the external power source during a cleaning process such that the cleaning apparatus operates cordlessly during the cleaning process,
wherein the heat store is configured to keep the cleaning fluid at a predefinable operating temperature during the cleaning process,
wherein the display device is configured to indicate that an operating temperature of the cleaning fluid has been reached, and
wherein the display device comprises a whistle.

36. The apparatus of claim 35 , wherein the whistle is arranged in the vicinity of the discharge device.
