Definitions

  • the invention relates to a high-pressure cleaning device having at least one storage container, which has a filling opening for a liquid and a closure device, with which the filling opening is closable and releasable.
  • the liquid to be introduced into the at least one storage container can be, for example, a cleaning chemical which can be added to the cleaning liquid to be dispensed from the high-pressure cleaning device, preferably water, to increase the cleaning effect.
  • a cleaning chemical which can be added to the cleaning liquid to be dispensed from the high-pressure cleaning device, preferably water, to increase the cleaning effect.
  • a descaling solution by means of which the risk of calcium deposits on the liquid-conducting components of the high-pressure cleaning device can be reduced.
  • Approved filling opening in this case does not mean that the filling opening must be fully released. It can also be provided that the filling opening is only partially released.
  • Object of the present invention is to develop a generic high-pressure cleaning device so that the at least one reservoir can be filled in a simpler manner.
  • the closure device has a lid section for closing the filling opening and a filling section with which a filling cross-sectional area which is larger than the cross-sectional area of the filling opening can be formed with the filling opening released.
  • “Filling cross-sectional area” is understood to mean a surface which can be struck or measured by the liquid to be filled into the at least one storage container in order to still accurately fill the liquid into the at least one storage container.
  • the filling cross-sectional area can be enlarged by means of the filling section of the closing device relative to the cross-sectional area of the filling opening. This makes it easier for a user to fill the at least one storage container with the liquid. As a result, the risk of liquid spilling inadvertently during filling is reduced, i. is poured next to the filling opening. On the one hand, this avoids possible waste of the liquid to be filled. On the other hand, the danger of a possible hazard to the user or the environment can be reduced, which can be given in particular by spilled aggressive liquids such as cleaning chemicals.
  • the high-pressure cleaning device according to the invention is also easier to handle.
  • a separate filling aid for filling the liquid into the at least one storage container for example a separate funnel.
  • the enlarged filling cross-sectional area can be formed by transferring the closure device from a closed position in which the lid section closes the filling opening into a filling position in which the filling opening is released.
  • Such an embodiment facilitates the handling of the closure device for the user. By transferring the closure device from the closed position into the filling position and vice versa, the user can release or close the filling opening.
  • a technically simple embodiment of a closure device can be achieved in that the closure device is movably mounted on the high-pressure cleaning device.
  • the closure device is pivotally mounted on the high-pressure cleaner.
  • the lid portion can form a hinged lid for the filling opening and can be transferred by pivoting from a closed position into a filling position and vice versa.
  • the closure device is mounted displaceably on the high-pressure cleaner.
  • the lid portion can in particular form a sliding cover for the filling opening, which can be transferred by moving from a closed position to a filling position and vice versa.
  • the filling section is arranged at the closed filling opening in the at least one storage container.
  • the filling section which is not used when the filling opening is closed, can be stored in this way in a space-saving manner in the at least one storage container. As a result, it is not possibly arranged disturbingly outside the at least one storage container. If the closure device as explained above can be transferred from a closed position by pivoting into a filling position and vice versa, then a filling section formed in this way can be pivoted out of the at least one storage container and pivoted back into it by pivoting the closure device.
  • a structurally simple and compact design of the closure device can be achieved if the filling section is arranged on the cover section.
  • the filling section is designed as a chute.
  • the filling section engages with the filling opening released with one end into the filling opening or passes through it.
  • Liquid which on the filling section for filling the at least one storage container is poured, can be passed in this way particularly reliable in the at least one reservoir. This reduces the risk of spilling liquid.
  • the filling section is designed as a pouring chute as described above, then it can engage with one end into the filling opening or reach through it, thereby providing a well-shaped liquid jet.
  • the filling section is curved or bent along its longitudinal extent.
  • Such a filling section can be arranged in a space-saving manner in the at least one storage container when the filling opening is closed. This is possible, for example, if the filling section is designed as a curved discharge chute, which circulates an edge of the filling opening when transferring the closure device from a closed position into a filling position and vice versa arcuately.
  • the closure device has at least one locking member for securing its position when the filling opening is closed.
  • the locking member may be formed, for example, as a locking element which cooperates with a further correspondingly formed locking element on the at least one reservoir for securing the position of the closure device.
  • the closure device has at least one locking member for securing its position with the filling opening released. This ensures, for example, that the closure device does not inadvertently move so when the filling opening is released that the filling process of the at least one storage container could be impaired.
  • a suitable locking member may be formed, for example, as a latching element which engages with an enabled filling opening with an edge of the filling opening.
  • the closure device comprises a sealing element for sealing the filling opening when the filling opening is closed.
  • a sealing effect can be achieved in a technically simple manner, for example, by virtue of the fact that the cover section has a sealing element which, when the filling opening is closed, rests sealingly against an edge thereof.
  • the closure device preferably comprises an identification area for identifying the liquid to be filled into the at least one storage container. In this way it is easy for a user to recognize which liquid is to be filled in the at least one storage container. An incorrect filling of the at least one storage container is thereby largely avoidable.
  • the marking area is designed such that suitable for labeling elements such as signs, plaques or the like are releasably connectable to the closure device. Such a closure device can be used universally.
  • the closure device is at least partially colored in a signal color.
  • the lid portion may be colored in a signal color.
  • a signal color is understood as meaning a color which can be regarded by a user as an optical means of information, such as, in particular, a strong red.
  • the high-pressure cleaning device has a plurality of storage containers and correspondingly a plurality of filling openings, it is of course possible to mark each of the closure devices with a different signal color in order to allow the user to fill the storage containers intuitively.
  • closure device is formed in one piece, because it can be produced in a cost effective manner. It can be made in particular as a one-piece plastic molding.
  • the filling opening of the at least one storage container is arranged on a rear side of the high-pressure cleaning device, based on its main direction of movement.
  • the high-pressure cleaner usually comprises at least one handle for moving.
  • the arrangement of the filling opening at the back is therefore accessible to the user in a simple manner and saves him unnecessary ways around the high-pressure cleaner around to reach the filling opening.
  • the term "back side" means, in addition to a rear wall or a section delimiting the high-pressure cleaning device, regions of lateral boundaries of the high-pressure cleaning device which are adjacent to the rear wall or the said section.
  • the high-pressure cleaning device preferably has operating elements and / or electrical fittings which are arranged above the filling opening of the at least one storage container on the high-pressure cleaning device. If liquid to be filled into the at least one storage container is to be spilled, the risk of a short circuit due to spilled liquid entering the operating elements and / or electrical fittings can be reduced in this embodiment.
  • the controls and / or the electrical fittings are preferably arranged on the back of the high-pressure cleaner. This makes it possible to create a uniform operating concept for the high-pressure cleaning device, in which the operation of the high-pressure cleaning device of only one side, namely the back, is possible.
  • connections for supplying and / or discharging resources such as water or electricity, which are required for operation of the high-pressure cleaner are also preferably arranged on the back of the high-pressure cleaner. Thereby can create a particularly pronounced uniform operating concept for the high-pressure cleaning device.
  • the high-pressure cleaning device has a heatable heat exchanger for heating a cleaning liquid to be dispensed from the high-pressure cleaning device, because by heating the cleaning liquid, its cleaning effect can be increased.
  • the high-pressure cleaning device may comprise a reservoir which is designed for receiving a fuel, in particular a fossil fuel, for the operation of the heatable heat exchanger.
  • FIGS. 1 and 2 A preferred embodiment of a high-pressure cleaner according to the invention is in the FIGS. 1 and 2 represented the drawing and there occupied by the reference numeral 10.
  • the high-pressure cleaning device 10 comprises a support frame, not shown in the drawing, on which on a front side 12 of the high-pressure cleaning device 10, two each pivotable about a vertical axis steering rollers 14 and 16 are arranged. Behind the castors 14 and 16, at a distance from a front 18 of the high-pressure cleaner 10, which corresponds to about two-thirds of the length of the high-pressure cleaner 10, two non-rotatable wheels 20 and 22 are arranged. These are rotatable about a common axis of rotation 24.
  • a rear side 26 of the high-pressure cleaner 10 includes a section 28 rearwardly delimiting the high-pressure cleaner 10, which in the following will be referred to simply as "rear wall" 30, even if it is formed from different components and does not constitute a "wall” in the conventional sense. Further, the back 26 are also areas of a left Side panel 32 and a right side panel 34, which are adjacent to the rear wall 30, attributed.
  • the high-pressure cleaner 10 includes a hood 36 covering the front and middle portions of the high-pressure cleaner 10, and a peripheral panel 38 in the lower portion of the high-pressure cleaner 10. Its areas near the back wall 30 are also attributed to the back 26.
  • the hood 36 is releasably connectable to the high-pressure cleaning device 10 and covers during operation of the high-pressure cleaning device 10, not shown in the drawing pump unit and a likewise not shown in the drawing heatable heat exchanger. These are mounted on the support frame.
  • cleaning fluid to be dispensed from the high-pressure cleaning device in this case water, can be pressurized. This can be heated by means of the heatable heat exchanger to increase the cleaning effect.
  • a pair of cable hooks 40 and 42 for receiving an electric cable is arranged, which serves the power supply of the high-pressure cleaning device 10.
  • a pair of handles 44 and 46 for moving the high-pressure cleaner 10 are positioned above the cable hooks 40 and 42.
  • the high pressure cleaning device 10 are preferably moved sliding, but also pulling.
  • the high pressure cleaning device 10 can be acted upon by the handles 44 and 46 with a directed to the ground force. This allows the high-pressure cleaner 10 to tilt about the rotation axis 24 of the wheels 20 and 22. As a result, the castors 14 and 16 are raised from the ground, so that the bumps can be overcome in a simple manner.
  • the great leverage has been found that can be achieved by the large distance of the axis of rotation 24 of the handles 44 and 46.
  • the position of the axis of rotation 24 is selected such that it has a distance from the front face 18 which corresponds approximately to two-thirds of the length of the high-pressure cleaning device 10.
  • the latter comprises at a lower portion 48 of the rear wall 30 a recess 50 formed in the circumferential lining 38, which is bounded in sections by a profiled foot rest 52.
  • a profiled foot rest 52 In support of the application of force to the handles 44 and 46, the user can act on the footrest 52 with a jamming force directed towards the floor for simplified tilting of the high-pressure cleaning device 10.
  • the cable hooks 40 and 42 can also be used for moving and tilting the high-pressure cleaning device 10.
  • the high-pressure cleaning device 10 between the handles 44 and 46 comprises an operating device 54 with operating elements 56, 58 and 60 as well as status displays 62 and 64.
  • Water to be dispensed from the high-pressure cleaning device 10 can be supplied to it via a water inlet 66 arranged on the lower section 48 of the rear wall 30.
  • pressurized water can be removed via a water outlet 68 which is disposed adjacent to the water inlet 66.
  • a washing lance for spraying the water can be connected to the water outlet 68 via a high-pressure hose likewise not shown in the drawing.
  • the high-pressure cleaning device 10 comprises a heatable heat exchanger. This is by means of a fuel, in particular a fossil fuel, operable.
  • the fuel is associated with a reservoir, which is not visible in the drawing, because it is hidden by the left side panel 32.
  • a filling opening of the storage container is closed by means of a closure lid 70 which is arranged near the cable hook 40 on the rear side 26.
  • the high-pressure cleaning device 10 comprises a reservoir, not shown in the drawing, which is covered by the right side panel 34 and serves to receive a descaling solution.
  • a descaling solution By means of the descaling solution, the risk can be reduced that lime deposits in the water-carrying components of the high-pressure cleaning device 10.
  • the reservoir for the descaling solution has a filling opening, which is arranged near the cable hook 42 on the back 26 and closed by a closure lid 72.
  • the high-pressure cleaning device 10 comprises two further reservoirs 74 and 76.
  • the filling openings 82 and 84 are formed between the operating device 54 and the lower portion 48 of the rear wall 30. They serve to hold liquid cleaning chemicals that can be added to the water to be dispensed from the high-pressure cleaning device 10 to increase the cleaning effect.
  • the dosage of the cleaning chemicals can be adjusted by means of the control element 56.
  • the storage containers 74 and 76 are associated closure devices 78 and 80, by means of which the filling openings 82 and 84 of the reservoir 74 and 76 are releasable and closable.
  • the closure devices 78 and 80 are identical in construction. In the following, therefore, with reference to the closure device 78, the features of the closure devices 78 and 80 are given the same reference numerals. Likewise, the corresponding features of the reservoir 74 and 76 are given the same reference numerals.
  • the Figures 3 and 4 show the closure device 78 in perspective and in side view. It is made in one piece as a plastic molded part and comprises a cover section 86 for closing the filling opening 82. It has a flat area 88 which can rest on the outside on a cylindrical edge 90 of the filling opening 82 for closing the filling opening 82 ( FIG. 6 shown there with the filling opening 84 and the closure device 80).
  • the lid portion 86 Protruding from the flat area 88, the lid portion 86 comprises a cylindrical projection 92 which can substantially positively engage the cylindrical rim 90 of the fill opening 82 for improved closure thereof.
  • a particularly good sealing effect can be achieved in that the cylindrical projection 92 has a circumferential annular groove 94, in which a sealing ring 96 is arranged, which seals against an inner surface 98 of the edge 90 of the filling opening 82 when the filling opening 82 is closed.
  • the position of the closure device 78, in which the filling opening 82 is closed by means of the lid section 86, is referred to as the closed position of the closure device 78.
  • a blocking element 100 in the form of a latching hook 102 is arranged on the flat area 88 of the lid portion 86.
  • the latching hook 102 can cooperate with a latching nose 104 projecting from the edge 90 of the filling opening 82 for securing the position of the closure device 78 in the closed position.
  • the lid portion 86 comprises two bearing elements in the form of bearing journals 106 and 108, by means of which the closure device 78 is pivotally mounted on a wall 110 of the reservoir 74.
  • the closure device 76 can be pivoted from the closed position into a filling position, i. be transferred.
  • the filling position is defined by the fact that the filling opening is released.
  • the cover portion 86 therefore forms as a whole a hinged lid for the filling opening 82.
  • the closure device 78 can be transferred by pivoting in the opposite direction from the filling position to the closed position.
  • the closure device 78 comprises a filling section 114.
  • the latter is in the form of a pouring channel 116 formed on the lid section 86 and projecting therefrom.
  • the chute 116 is curved so that its surface 117, which faces the user in the filling position of the closure device 78, forms a "saddle surface" ( Figures 3 and 5 ).
  • the dimensions of the chute 116 are dimensioned so that their free end 118 in the filling position of the closure device 78 passes through the filling opening 82 and engages in a container interior 119 of the storage container 74.
  • the chute 116 is open at its free end 118.
  • the cleaning chemical to be introduced into the reservoir 74 can therefore be poured in the filling position from above onto the surface 117 of the chute 116, which introduces the cleaning chemical into the container interior 119.
  • the filling section 114 thus serves to assist the filling of the storage container 74.
  • a filling cross-sectional area can be formed through it which is enlarged in relation to the cross-sectional area of the filling opening 82.
  • the term "filling cross-sectional area" is understood to mean the area which has to be hit by the user with the liquid in order to accurately fill it in the container interior 119. It therefore comprises the surface 117 and the cross-sectional area of the shared filling opening 82.
  • locking members 120, 122, 124 and 126 are arranged near the free end 118 of the chute 116 ( Figures 3 and 4 ). These are in the form of latching projections 128, 130, 132 and 134, respectively, and can engage in the filling position with the edge 90 of the filling opening 82. This is schematically in FIG. 5 shown. Due to the existing engagement between the locking projections 128, 130, 132 and 134 and the edge 90, the closure device 78 is secured against pivoting and remains in the filling position until it is pivoted by the user after filling the reservoir 74 back into the closed position.
  • the chute 116 rotates in an arcuate manner as a result of its curved configuration during pivoting of the closure device 78 from the filling position to the closed position and vice versa the edge 90 of the filling opening 82.
  • the filling section 114 is arranged to save space in the container interior 119 in the closed position ( FIG. 6 ).
  • the lid portion 86 On its side facing away from the reservoir 74 side 136, the lid portion 86 has a marking area 138, on which a shield 140 releasably is arranged connectable.
  • the shield 140 serves to identify the reservoir 74 and thus the cleaning chemical to be filled into the reservoir 74.
  • the closure device 78 can be used universally, as shown in the present case by the fact that it is also used (in the form of the closure device 80) for the reservoir 76.
  • an identification symbol can be formed directly on the closure device 78.
  • the shutter 78 is uniformly colored in a signal color so that it can be easily recognized by the user.
  • the arrangement of the operating device 54, the water inlet 66, the water outlet 68 and all filling openings of the reservoir of the high-pressure cleaner 10 on the back 26 creates a uniform operating concept for the high-pressure cleaner 10, in particular in combination with the also arranged on the back 26 handles 44 and 46 and For moving, for operation and for filling the reservoir of the high-pressure cleaner 10 is therefore only the access from one side, namely the back 26, for the user required.
