Definitions

the invention relates to a surface cleaner with suction and simplified operation according to the preamble of patent claim 1.
a surface cleaner with suction for example, is part of the DE 20 2011 107 459 U1 known.
the surface cleaner shown there has a 3-way valve with the aim of enabling a total of three operating states.
a first operating state is reached via a first valve position of a 3D valve and provides that the high-pressure operated rotor arm with the spray nozzles located thereon and a suction device are operated together.
a second operating state provides that the high-pressure medium fed in via a high-pressure source is fed exclusively to a suction device, which sucks off the water accumulating inside the housing and directs it into a connected waste water hose.
a third operating state provides a third valve position in which high-pressure cleaning takes place without switching on the cut-off device.
the surface cleaner shown has the disadvantage of being more difficult to operate, because to set the three different operating modes, the user has to lean down towards the bottom housing of the device and set the various valve positions by hand.
Such a device has not been able to establish itself because of the associated interruption to operations and the further associated risk of infection and the slower mode of operation.
the high-pressure gun is removed from the drawbar and the remaining dirt residue on the floor is removed in a separate operation.
the DE 100 66 009 A1 shows a surface cleaner with a push rod consisting of two mutually parallel tubes, with a single actuating handle for a high-pressure gun being arranged on one tube.
the handle arranged on the adjacent other tube of the drawbar has no actuating function.
the suction power can only be adjusted using a hand lever attached directly to the housing, which means increased effort for operation.
the hand lever can only be actuated when the operator is bent over above the housing.
a surface cleaner which distributes the cleaning liquid without using a high-pressure pump onto a surface to be cleaned with a rotatingly driven liquid distributor and sucks it off with a vacuum arrangement.
a brush shut-off device is arranged as an electric switch on the right-hand handle of the two-arm push-bar, and on the left-hand side there is a manually operated rotary valve, with which the flow of cleaning liquid to the rotating liquid distributor can be controlled.
the invention therefore has the task of providing a surface cleaner according to the subject of DE 20 2011 107 459 U1 or the DE 100 66 009 A1 further training in such a way that uninterrupted operation of the surface cleaner in several operating states is possible and that during operation an easy and manageable changeover from a high-pressure surface cleaning operation alone to a suction operation alone and finally to a dual function consisting of high-pressure and suction operation is possible.
the invention is characterized by the technical teaching of claim 1 in order to solve the task at hand.
the advantage of the present invention is that in the area of a push rod there are two actuating handles that can be actuated independently of one another and are preferably attached to one end of the push rod, preferably at the same height and next to one another.
the two actuating handles are thus within reach of a standing person and can easily be actuated individually or together during operation of the surface cleaner - each with the fingers of one hand. Accordingly, two-handed actuation of the actuation handles, which are spatially separated from one another, is provided.
a first operating state when one operating handle is actuated, the high pressure is sent directly to the rotor arm of the surface cleaner - assuming that the other operating handle is not actuated - so that in this first mode of operation only a high-pressure surface cleaning process takes place.
both actuating handles are actuated at the same time, suction is also made possible at the same time during high-pressure operation, which means a particularly simple, gentle and fast operating mode.
the present invention offers an advantage over the prior art, because the operator can now operate the two operating handles in the area of the operating fork without having to operate a valve close to the floor, remains in an upright working position and can also use the device during this operation move further on the ground and carry out the necessary cleaning work without interrupting operation.
the technical teaching according to claim 1 therefore leads to simpler, uninterrupted operation of such a surface cleaner with three different operating states.
both actuating handles are actuated in order to carry out the second operating state of suction in addition to the operating state of surface cleaning. It can happen that water remains on the cleaned surface.
the operating handle responsible for high-pressure cleaning is closed by releasing it and only the operating handle responsible for suction is actuated further, so that only suction takes place without further surface cleaning.
a further advantage of the invention is that if only the actuating lever for feeding in the high pressure is actuated, a high cleaning force (speed of rotation) is achieved on the rotor arm and the spray nozzles (high pressure) attached to it. However, if both actuating levers are actuated because the suction is switched on, the effective one drops Cleaning pressure on the cleaning surface decreases because it is partly made available for the suction device. The user can then operate the two operating levers alternately or simultaneously, always under visual control, in order to create a clean, cleaned surface that has been freed from water residues.
the suction capacity of the Venturi nozzle used must therefore be matched to the cleaning effect of the high-pressure arm, which has been achieved ideally with the above-mentioned ratio.
the two actuating handles are designed as pistol grips, as is usual with high-pressure pistols for high-pressure cleaners.
Each pistol-style grip has an actuating lever that can be manually actuated.
actuating handles with associated adjusting levers can also be used, such as ball valves with a ball valve or actuating elements that have rolling elements or similar actuating elements instead of an actuating lever.
the invention is therefore not dependent on the design of the actuating handle as a pistol grip, but rather provides any other form of actuating handle.
a further feature of the invention provides that there is a pressure relief valve on the inlet side of the suction device, which bypasses the Venturi nozzle via a bypass line in the event of excess pressure and opens the bypass if a set high pressure is exceeded. This prevents the venturi nozzle from being overloaded.
bypass water which is discharged via the bypass line from the pressure relief valve in the event of excess pressure, is fed to the outlet of the suction device and does not reach the floor.
the invention is not dependent on a drawbar with a push or operating fork attached to it.
a surface cleaner which consists essentially of an approximately pot-shaped and cylindrical housing 6, which is open on one side at the bottom and on the outer circumference of which a number of guide rollers 20 are arranged, distributed uniformly around the circumference.
the housing 6 forms according to figure 4 a double casing 27, which forms an annular gap 28 between the outer and inner casing, through which the suction on the cleaned surface takes place.
suitable suction nozzles can also be provided in the housing 6 in accordance with DE 20 2011 107 459 U1 be arranged.
the lower edge of the housing is sealed off from the cleaning surface on the bottom by means of a peripheral, self-contained, ring-shaped brush seal 29 which is arranged on the lower edge of the housing.
a rotor arm 7 is arranged with two opposing cleaning nozzles, which are directed obliquely against the direction of the rotor in order to achieve a rotation of the rotor arm 7 during high-pressure operation through the resulting recoil effect.
a forced high-pressure jet is emitted from cleaning nozzles onto the surface to be cleaned.
the invention is not limited to a single rotor arm 7 with two cleaning nozzles located opposite one another.
a cross arrangement of a rotor arm or several rotor arms can also be present.
the rotor arm 7 is rotatably attached to a pivot joint 5 in the center of the housing.
the high-pressure medium is fed through the rotary joint 5 to the rotor arm 7 .
a push rod 30 attaches to the housing, which consists of two mutually parallel drawbar tubes 16 in the exemplary embodiment shown, which fork in the area of the housing 6 and are pivotally accommodated there in the area of two pivot joints 17, 18 arranged at a distance from one another.
the drawbar 30 with its drawbar tube 16 branches at the top into two fork tubes 14, 15, which form an operating fork 11.
the two actuating handles 1, 3 according to the invention are each arranged at the ends of the operating fork 11.
the actuating handle 1 intended for the high-pressure cleaning mode is designed as a pistol grip and has a first actuating lever 25 , while the second actuating handle 3 intended for the suction mode has a further actuating lever 26 .
the high-pressure medium is fed into the actuating handle 1 via an HP connection 24 and is fed via a T-shaped adapter 2 at the same time as a connecting hose 23 to the input side of the other actuating handle 3 .
the high-pressure medium is constantly in contact with the HP connection 24 and the input side of the operating handle 1 and also the input side of the operating handle 3 .
the high-pressure medium is fed via the HP hose 4a into the housing-side, central swivel joint 5 for the pressure supply of the rotor arm 7, whereby the first operating mode is given, namely the high-pressure surface cleaning under the action of the cleaning nozzles on Rotor arm 7.
the operator optionally opens the (left) actuating handle 3 under his visual control in order to switch on the suction device 8 by actuating the actuating lever 26.
the suction device 8 is attached to the housing 6 .
a Venturi nozzle 9 is arranged, which is acted upon by the HP hose 4b with the HP medium when the actuating lever 26 on the actuating handle 3 is actuated, see FIG Figure.3 .
the operator can optionally switch on suction or not by actuating the actuating lever 26 in the actuating handle 3 .
a pressure relief valve 21 which has a bypass line 22 is therefore arranged on the inlet side of the suction device 8 .
the bypass line is shown with dashed lines in figure 1 and 2 drawn because it is located in the interior of the suction device 9.
the castors 20 of the chassis 19 shown here can also be designed in other ways. Roller elements, ball rollers, sliding elements, runners or the like can be used in this case. Overall, the technical teaching according to the invention results in a significant operating advantage and an improved working speed with an improved working result and better cleaning performance.
