Abstract

A mobile high-pressure cleaning apparatus is provided with a vehicle trailer, on the chassis of which at least two running wheels are held so as to be rotatable, and with a high-pressure cleaning appliance having a motor and a pump, and also with at least one water storage tank for storing water for the high-pressure cleaning appliance. So that water can be provided to the apparatus from the at least one water storage tank or from a water supply mains, without risk of water from the water supply mains being returned thereto, the high-pressure cleaning apparatus has a decoupling tank with at least one inlet which can be connected to the water supply mains, and at least one outlet which is connected to the high-pressure cleaning appliance and to at least one water supply tank via a shut-off member which can be actuated by the user.

First claim

The invention claimed is:

1. A mobile high-pressure cleaning apparatus with a vehicle trailer, on a chassis of which at least two running wheels are held so as to be rotatable about a common axis of rotation for moving the high-pressure cleaning apparatus, and with a high-pressure cleaning appliance having a motor and a pump driven by the motor for pressurizing water which can be directed at an object which is to be cleaned, and also with at least one water storage tank for storing water for the high-pressure cleaning appliance, wherein the high-pressure cleaning apparatus has a decoupling tank with at least one inlet which is adapted to be connected to a water supply mains, and with at least one outlet which is connected to the high-pressure cleaning appliance and to at least one water storage tank via a shut-off member which is adapted to be actuated by a user,
wherein the high-pressure cleaning apparatus has a first water storage tank and a second water storage tank which are arranged spaced apart from each other in each case on a long side of the vehicle trailer and are connected together via a line arrangement, the first water storage tank being arranged on a first long side of the vehicle trailer and the second water storage tank being arranged on a second long side of the vehicle trailer and the two water storage tanks being located on the chassis and the high-pressure cleaning appliance being positioned between the two water storage tanks on the chassis,
wherein the decoupling tank is integrated in the first water storage tank and is connected via a supply line to the high-pressure cleaning appliance and via a first connecting line which is adapted to be shut off to the second water storage tank,
wherein the second water storage tank is connected via a second connecting line to the first water storage tank, and
wherein the first water storage tank has an indentation which forms the decoupling tank.

2. The mobile high-pressure cleaning apparatus according to claim 1 , wherein the chassis has a frame on which the first water storage tank and the second water storage tank are located.

3. The mobile high-pressure cleaning apparatus according to claim 1 , wherein the first water storage tank and the second water storage tank extend over the entire length of the chassis.

4. The mobile high-pressure cleaning apparatus according to claim 1 , wherein at least one of the two water storage tanks has, facing the other water storage tank, at least one recess which forms a receptacle for an accessory part of the high-pressure cleaning appliance.

5. The mobile high-pressure cleaning apparatus according to claim 1 , wherein the high-pressure cleaning apparatus has a heating unit for heating the water pressurized by the pump, the heating unit being arranged on the chassis between the two water storage tanks.

6. The mobile high-pressure cleaning apparatus according to claim 5 , wherein the heating unit is configured as a fuel-operated continuous-flow heater.

7. The mobile high-pressure cleaning apparatus according to claim 1 , wherein a fuel tank, a cleaning-agent tank and/or an antifreeze tank are arranged between the two water storage tanks.

8. The mobile high-pressure cleaning apparatus according to claim 7 , wherein the fuel tank, the cleaning-agent tank and/or the antifreeze tank are accessible to the user from the rear side of the high-pressure cleaning apparatus.

9. The mobile high-pressure cleaning apparatus according to claim 1 , wherein a high-pressure hose wound onto a hose drum and/or an inlet hose wound onto a hose drum are arranged between the two water storage tanks.

10. The mobile high-pressure cleaning apparatus according to claim 9 , wherein the high-pressure hose and/or the inlet hose are accessible to the user from the rear side of the high-pressure cleaning apparatus.

11. The mobile high-pressure cleaning apparatus according to claim 1 , wherein an electric switch cabinet and/or a storage surface for a toolbox are arranged between the two water storage tanks.

12. The mobile high-pressure cleaning apparatus according to claim 11 , wherein the switch cabinet and/or the storage surface for the toolbox are accessible to the user from the rear side of the mobile high-pressure cleaning apparatus.

13. The mobile high-pressure cleaning apparatus according to claim 1 , wherein the high-pressure cleaning apparatus has at least one cover which is movable back and forth between a closed position and an open position, which in the closed position covers a region between the two water storage tanks and uncovers this region in the open position, and which is mounted movably on the two water storage tanks.

14. The mobile high-pressure cleaning apparatus according to claim 13 , wherein the at least one cover is mounted to be pivotable about a pivot axis oriented perpendicularly to a direction of travel on a first and a second bearing element, the first bearing element being formed on the first water storage tank and the second bearing element being formed on the second water storage tank, and the two bearing elements facing each other.

15. The mobile high-pressure cleaning apparatus according to claim 14 , wherein the two water storage tanks have in each case an extension arm oriented vertically upwards, on the upper end region of which is remote from the chassis the bearing elements are formed.

16. The mobile high-pressure cleaning apparatus according to claim 14 , wherein the bearing elements are configured as pivot pins.
