Definitions
- the invention relates to a high-pressure cleaning device with a housing, with a liquid pump arranged in the housing, with a motor, likewise enclosed by the housing, for driving the liquid pump, with a spray gun comprising a jet pipe and an actuating handle and with a liquid pump with the Hose connecting pistol.
- Such a device is known from US-A-4,972,944. It can be operated in two ways, namely once as a stationary device, the housing with the device parts enclosed by it being stationary, e.g. B. arranged on the ground and the spray gun connected via a hose to the liquid pump is grasped by hand on its actuating handle and directed at the locations to be cleaned.
- the jet pipe can also be connected directly to the housing and the liquid pump, the housing then being gripped by a special handle provided for this purpose, and the unit consisting of the jet pipe and housing onto the points to be cleaned judges.
- the object is achieved by connecting means for releasably attaching the spray gun to the housing such that the unit consisting of gun and housing can be handled by manually grasping the actuating handle of the gun.
- the spray gun thus remains permanently connected to the housing with its hose, but the unit consisting of the housing and the gun can be grasped on the actuating handle of the gun and, in the same way as the gun alone, can be precisely aligned to the points to be cleaned.
- FIG. 1 shows in side view a high-pressure Reini ⁇ supply device with an electric motor for driving _ a high pressure pump
- Figure 2 shows the device of Figure 1 in cross-sectional view
- 3 shows a high-pressure cleaning device with an internal combustion engine for driving a high-pressure pump
- FIG. 4 shows a front view of the device from FIG. 3.
- the high-pressure cleaning device shown in FIGS. 1 and 2 comprises a housing 1, which encloses a conventional liquid high-pressure pump 2.
- the pump 2 is driven by an electric motor 3.
- a flexible hose 4 extends from the pump 2 and is connected to a spray gun 5.
- the spray gun 5 in turn conventionally comprises a jet pipe 6 with a spray nozzle 7 and an actuating handle 8 into which the hose 4 opens.
- the actuating handle 8 comprises, in a manner known per se, a (not shown) manually operated switch for switching on and off a high-pressure spray jet emerging from the nozzle 7.
- the gun 5 is gripped manually on the actuating handle 8 and its nozzle is aligned with the point to be cleaned.
- the housing 1 with the components enclosed by it is parked stationary on the ground, while the spray gun 5, which is connected to the housing only via the flexible hose 4, is aimed freely at the point to be cleaned.
- the radius of action is of course limited by the length of the hose 4.
- the spray gun 5 can be detachably rigidly attached to the housing using connecting means according to the invention (still to be described) 1 can be attached.
- the spray guns 5 and the housing 1 form a fixed unit which can be gripped manually on the actuating handle 8 and aligned with the points to be cleaned.
- the operator carries the entire unit with him and is no longer limited in its radius of action by the length of the hose 4.
- the handling is preferably carried out in such a way that the unit with one hand, for. B. the right hand, is detected on the operating handle 8, while the other hand engages a handle 9 provided for this purpose on the jet tube 6.
- a handle which projects downwards or laterally (not shown), could also be provided rigidly on the housing 1.
- the connecting means for the detachable fastening of the spray gun 5 to the housing 1 comprise two annular tabs 11 which are firmly connected to the housing 1 and which are open on one side.
- a rotary member 12 is rotatably arranged, which has a radially extending, relatively wide slot 13. This slot 13 is oriented in FIG. 2 by corresponding rotation of the rotary member such that it is closed by the tab 11 at its opening. This is the normal operating position of the rotary member 12.
- the spray gun 5 and the housing 1 are connected to the unit shown in FIG. 1 in the manner described, this unit can be handled essentially like the spray gun alone, since the unit, like the spray gun 5 alone, detected on the actuating handle 8 and possibly on the handle 9.
- the relatively heavy housing 1 with the constituent parts enclosed by it swings freely about the axis of the spray gun 5 because of the described rotatable connection.
- the pedling attachment of the housing 1 to the spray gun 5 ensures that the housing 1 always hangs down so that the cooling air suction slots 10 provided on the housing 1 are always below the spray gun 5.
- the sections of the spray gun 5 which are complementary to the reveals of the slots 3 are designed such that at the same time they prevent an axial displacement of the spray gun 5 in the tabs 11.
- two corresponding ring members could also be rotatably arranged directly on the spray gun 5. These rotatable ring members are connected directly with the The housing is locked, so that a rotatable connection between the spray gun 5 and the housing 1 is also obtained again.
- the connecting means between the spray gun 5 and the housing 1 each comprise two tabs or ring members. Basically, it is sufficient to provide only a single tab or a single ring member, which in this case can then be made axially correspondingly longer, for example in the form of a bushing.
- splash protection elements in the form of foam mats are provided between it and the housing, which are designated in FIGS. 1 and 2 with the reference numerals 14 and 15, respectively.
- These splash protection mats allow cooling air for the electric motor 3 to enter and exit, but prevent the ingress of moisture.
- a labyrinth-like air duct in the housing 1 can also be provided as a splash guard in order to prevent water droplets from penetrating into live parts of the electric motor 3.
- the housing 1 of the high-pressure cleaning device 1 is advantageously designed as a plastic injection-molded part, a film hinge preferably being formed at the point indicated by the arrow 16 in FIG. 2, and the housing 1 can thus be produced in one piece from two half-shells .
- the unit consisting of the housing 1 and the spray gun 5 can also be connected to a carrying strap 17, which allows an operator to carry the unit hanging over the shoulder. In this case the weight of the unit is absorbed by the shoulder and the operator needs e.g. B. to grasp the operating handle 8 with only one hand in order to draw the spray jet towards the point to be cleaned.
- the shoulder strap 17, which can be attached to the tabs 11, for example, by eyelets, furthermore has a handle 18 connecting the two parts of the shoulder strap 17, which is made of the same flexible material as the shoulder strap 17 and on which the mentioned unit is detected and carried ⁇ can be gen.
- FIGS. 3 and 4 differs from that according to FIGS. 1 and 2 only in that a conventional (not visible) internal combustion engine is arranged in the housing 1 instead of the electric motor 3. Otherwise, the device according to FIGS. 3 and 4 corresponds in terms of its construction and function to the embodiment according to FIGS. 1 and 2.
- the tabs 11 attached spray gun 5 provide vibration damping means that prevent the inevitable vibrations emanating from the internal combustion engine on the spray gun and thus on the hands of an operator holding this spray gun.
- vibration damping elements are known per se and therefore do not need to be described in detail here.
