Embodiment Construction

[0039] specific implementation plan

[0040] figure 1 and figure 2 An advantageous embodiment of the high-pressure cleaning device according to the invention is shown schematically, which is identified as a whole by the reference numeral 10 . The high-pressure cleaning device 10 has a housing 12 . Arranged in this housing 12 is a motor-pump unit 14 which has an electric motor 16 and a pump 18 which is driven by the electric motor 16 . The pump 18 has a pump inlet 20 and a pump outlet 22 . The pump inlet 20 is fluidically connected to a connection element 24 to which a supply line, in particular a suction line, can be connected. Such supply lines are known to those skilled in the art and are therefore not shown in the figures.

[0041] On the housing 12 , the first roller 26 and the second roller 28 are mounted rotatably about a common axis of rotation 30 . The high-pressure cleaning device 10 can be moved on rollers 26 , 28 . For this purpose, high pressure cleaning eq...

Abstract

The invention relates to a high-pressure cleaning device (10), comprising: - a housing (12), on which two running wheels (26, 28) are mounted for rotation about a common axis of rotation (30) and in which a motor (16) and a pump (18) driven by the motor (16) are arranged; - a pressure hose (122) fluidically connected to an outlet (22) of the pump (18); and - a winding apparatus (40) which has a rotatably mounted hose drum (50) for winding and unwinding the pressure hose (122), wherein the high-pressure cleaning device (10) can be tilted about the axis of rotation (30) of the running wheels (26, 28) from a usage position into a transport position. According to the invention, in order to develop the high-pressure cleaning device (10) in such a way that the pressure hose (122) can be wound ina simpler way, the winding apparatus (40) has a restoring spring (70) and a blocking mechanism (51), wherein the restoring spring (70) can be loaded by unwinding of the pressure hose (122) from the hose drum (50) and the hose drum (50) can be set into rotation by the restoring spring (70) in order to automatically wind the pressure hose (122), and wherein the hose drum (50) can be automatically locked by means of the blocking mechanism (51) and released by the application of a tensile force to the pressure hose (122).

Description

technical field [0001] The invention relates to a high-pressure cleaning device having a housing on which two rollers are mounted rotatably about a common axis of rotation and in which a motor-pump unit with a motor and a pump driven by the motor is arranged, the high-pressure The cleaning device has a pressure hose, which is fluidly connected to the outlet of the pump, and a winding device, which has a rotatably mounted hose reel for winding and unwinding the pressure hose, wherein The high-pressure cleaning device can be tilted from the use position about the axis of rotation of the roller into the transport position. Background technique [0002] With such a high-pressure cleaning device, cleaning fluid, preferably water, can be under pressure and be discharged via a pressure hose. The high-pressure cleaning device has a motor-pump unit which contains a motor and a pump driven by the motor. Preferably electric motors are used. The pump has an inlet through which cleani...
