Description

Technical Field

[0001] The invention relates to a pressure cleaning system, which comprises a pressure cleaning device having a pump, a motor for driving the pump, a device inlet for inputting a cleaning liquid to be put under pressure and a device outlet for outputting the cleaning liquid under pressure, and the pressure cleaning system also comprises a container unit, the container unit having a storage container for the cleaning liquid to be put under pressure and a device receptacle, the pressure cleaning device being insertable into the provided receptacle in an insertable direction in a removable manner, wherein the device receptacle is arranged at a first container side of the container unit and the pressure cleaning device protrudes from the device receptacle in the insertable position and the device inlet is in flow connection with the storage container in the insertable position of the pressure cleaning device. Background Art

[0002] With the help of such a pressure cleaning system, it is possible to clean a surface or an object without the need to deliver a cleaning liquid from the outside in the following manner, that is, the pressure cleaning device takes up its position in the device receiving portion of the container unit and can thus deliver the cleaning liquid, such as water, contained in the storage container to the device inlet of the pressure cleaning device. The cleaning liquid of the pressure cleaning device can be placed under pressure with the help of a pump. The pressure can be greater than 10 bar, for example, 20 bar to 30 bar, in particular 25 bar. The cleaning liquid placed under pressure can be output from the pressure cleaning device via the device outlet. A liquid output line, such as a pressure hose, can be connected to the device outlet. The cleaning liquid can be delivered to a liquid output mechanism, in particular a spray gun or a spray bar, via the liquid output line.

[0003] Alternatively, it is also possible to supply the cleaning liquid to the pressure cleaning device via an external liquid supply line, for example via a suction hose or a garden hose. For this purpose, the pressure cleaning device can be removed from the device receptacle of the container unit in the opposite direction of insertion. The device inlet of the pressure cleaning device is then freely accessible and can be connected to the external liquid supply line.

[0004] The pressure cleaning device can therefore be operated both with and without a container unit, thus covering a wide range of application areas.

[0005] A pressure cleaning system of the type mentioned at the outset is known from document CN 203591966 U. The pressure cleaning system comprises a pressure cleaning device with an electrically driven pump, a device inlet and a device outlet, and a container unit with a storage container for a cleaning liquid to be put under pressure and a device receptacle, the device receptacle being arranged at a first container side of the container unit. The pressure cleaning device can be inserted detachably into the device receptacle of the container unit with a flow connection formed between the storage container and the device inlet of the pressure cleaning device. When operating the pressure cleaning system, in particular when inserting the pressure cleaning device into the device receptacle of the container unit and when removing the pressure cleaning device from the device receptacle of the container unit, there is a risk that the container unit will tip over. Summary of the invention

[0006] The object of the present invention is therefore to improve a pressure cleaning system of the type mentioned at the outset in such a way that it has greater standing safety.

[0007] This task is solved in a similar pressure cleaning system according to the invention in that the first container side of the container unit is tilted obliquely in the direction of the second container side of the container unit facing away from the first container side, wherein the spacing between the first container side and the second container side increases in the insertion direction, wherein the insertion direction extends vertically from top to bottom in the vertical use position of the pressure cleaning system. With this design, a lower center of gravity with respect to the vertical use position and thus a higher standing safety of the pressure cleaning system can be achieved. The pressure cleaning device can also be inserted from above into the device receiving portion of the container unit with respect to the vertical use position of the pressure cleaning system and removed upward from the device receiving portion of the container unit. The risk of tipping over can thus be kept very small.

[0008] For particularly simple handling, the pressure cleaning device preferably has a device longitudinal axis which, when the pressure cleaning device is in the inserted position, is oriented parallel to the insertion direction.

[0009] For a compact design of the pressure cleaning system, it is advantageous if the container unit has a substantially triangular shape, preferably a triangular shape with rounded corners, in a side view.

[0010] Advantageously, the device outlet is arranged at a region of the pressure cleaning device that projects from the device receptacle of the container unit when the pressure cleaning device is in the inserted position. This allows good accessibility to the device outlet. A liquid discharge line, such as a pressure hose, can be connected to the device outlet.

[0011] For handling purposes, the pressure cleaning device has, in the inserted position, a device front facing away from the second container side of the container unit, which in the inserted position of the pressure cleaning device projects out of the device receptacle, wherein the device outlet is arranged at the device front side.

[0012] Preferably, the device front side of the pressure cleaning device has a lower section and an upper section with respect to the vertical use position of the pressure cleaning system, wherein the device outlet is arranged at the lower section. As already mentioned, the liquid discharge line can be connected to the device outlet. When a pulling load is applied to the liquid discharge line, a tipping moment can act on the pressure cleaning system. By arranging the device outlet at the lower section, i.e., near the center of gravity of the pressure cleaning system, the risk of tipping can be kept low.

[0013] It can be provided that the pressure cleaning device has at least one accessory holder, which, when the pressure cleaning device is in the inserted position, is arranged at a region of the pressure cleaning device that projects from the device receptacle of the container unit. Accessories, such as a spray gun or a spray lance, can be detachably fastened to the at least one accessory holder. This allows the operator to easily access the accessories.

[0014] Preferably, the pressure cleaning device has a first longitudinal side and a second longitudinal side facing away from the first longitudinal side, wherein the two longitudinal sides each have a side section which, when the pressure cleaning device is in an inserted position, protrudes from the device receptacle, wherein at least one accessory holder is arranged on at least one side section. This allows particularly simple access to the at least one accessory holder.

[0015] Advantageously, a first accessory holder is arranged on a side section of a first longitudinal side of the pressure cleaning device that projects out of the device receptacle when the pressure cleaning device is inserted, and a second accessory holder is arranged on a side section of a second longitudinal side of the pressure cleaning device that projects out of the device receptacle when the pressure cleaning device is inserted. This allows a plurality of accessories, such as spray guns and spray lances, to be arranged.

[0016] Advantageously, the pressure cleaning device has a grip, which is arranged at a region of the pressure cleaning device that projects from the device receptacle of the container unit when the pressure cleaning device is in the inserted position. The pressure cleaning device can be gripped at the grip and can be easily inserted into or removed from the device receptacle of the container unit.

[0017] For particularly simple operability it is advantageous if the handle is arranged on the device front side of the pressure cleaning device.

[0018] In an advantageous embodiment of the invention, the pressure cleaning device has a switch for switching the pressure cleaning device on and off, wherein the switch is arranged above the handle relative to the vertical use position of the pressure cleaning system. The switch is thus easily accessible and the pressure cleaning device can be switched on and off in a simple manner.

[0019] Advantageously, the pressure cleaning device has a battery for powering the motor, wherein the battery can be inserted detachably into a battery receptacle of the pressure cleaning device and the battery receptacle is arranged at a region of the pressure cleaning device that projects from the device receptacle of the container unit when the pressure cleaning device is inserted. The battery is thus easily accessible to an operator. Replacement of the battery is therefore very simple.

[0020] The battery is preferably rechargeable.

[0021] Advantageously, the battery receptacle is arranged on the upper side of the pressure cleaning device that points upward in the upright position of use of the pressure cleaning system. This makes it particularly convenient for the operator to access the battery.

[0022] In order to facilitate the transport of the pressure cleaning system, the container unit advantageously has two wheels which can be mounted about a common axis of rotation for moving the pressure cleaning system.

[0023] For particularly comfortable transport of the pressure cleaning system, it is advantageous if the container unit has a push frame that can be moved back and forth between a retracted position and an extended position, wherein the push frame is designed in a U-shape and has two arms connected to one another by a crossbeam, wherein each arm is movably supported on a guide channel of the container unit. If the pressure cleaning system is to be transported by movement, the push frame can be moved from its retracted position into its extended position. The operator can hold the crossbeam and move the pressure cleaning system using the wheels. At the place of use or in storage, the push frame can be moved from the extended position back into the retracted position, so that the pressure cleaning system takes up very little space.

[0024] The container unit advantageously has a container underside in which a groove is formed. This design allows the operator to lift the pressure cleaning system in a simple manner by holding the crossbar of the push frame in its retracted position with one hand and grabbing into the groove with the other hand.

[0025] Preferably, the container unit has a storage space for storing accessories at its second container side. For example, a pressure hose can be stored in the storage space.

[0026] In order to fill with cleaning liquid, the storage container has, in an advantageous embodiment, a filling connection which can be closed liquid-tightly by means of a cover, wherein the ventilation valve is integrated into the cover. If cleaning liquid is removed from the storage container during operation of the pressure cleaning system, for example via a liquid outlet line connected to the device outlet, a negative pressure is generated in the storage container. Due to the pressure difference between the interior of the storage container and the surroundings, the ventilation valve opens so that air can flow into the storage container. If no cleaning liquid is removed from the storage container, there is no pressure difference between the interior of the storage container and the surroundings. The ventilation valve is therefore closed so that, for example, no cleaning liquid can escape from the storage container during transportation.

[0027] The ventilation valve is preferably made of an elastomeric material.

[0028] The cap is advantageously designed as a screw cap.

[0029] For simple assembly, it is advantageous if the cover has a recess which is delimited by the bottom in the direction of the storage container, wherein the bottom has a perforation in which the ventilation valve is arranged. The dimensions of the perforation and the ventilation valve are matched to one another so that there is a slight compression by which the ventilation valve is held in the perforation.

[0030] The recess can advantageously be closed with a cover, so that the ventilation valve can be protected from external influences, such as dirt. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] exist Figures 1 to 8 Schematically showing a preferred embodiment of a pressure cleaning system according to the invention, the pressure cleaning system is generally denoted by reference numeral 10 .

[0041] The pressure cleaning system 10 comprises a pressure cleaning device 12 and a container unit 14. The pressure cleaning device 12 can be inserted into a device receptacle 18 of the container unit 14 in an insertion direction 16 and can be removed from the device receptacle 18 when necessary. The insertion direction 16 is the direction of the pressure cleaning system 10. Figures 1 to 6 In the upright position of use shown in FIG. 1 , the pressure cleaning device 12 extends vertically from top to bottom. When the pressure cleaning device 12 is positioned in the device receptacle 18 of the container unit 14 , the device longitudinal axis 20 is oriented parallel to the insertion direction 16 .

[0042] The pressure cleaning device 12 comprises a motor 22 and a pump 24. The pump 24 is in flow connection with an equipment inlet 26 of the pressure cleaning device 12, through which a cleaning liquid to be put under pressure can be supplied to the pump 24. The pump 24 puts the cleaning liquid under pressure. The cleaning liquid put under pressure can be discharged from the pressure cleaning device 12 via an equipment outlet 30 which is in flow connection with the pump 24. A liquid discharge line, for example a pressure hose, which is known per se and is therefore not shown in the drawing for a better overview, can be connected to the equipment outlet 30.

[0043] The container unit 14 comprises a storage container 32 for a cleaning liquid to be placed under pressure. In order to fill it with cleaning liquid, an inlet nozzle 36 which can be closed liquid-tightly by a cover 34 with a seal 34a arranged in the middle is arranged at the storage container 32. A recess 33 is formed in the cover 34, which is limited by a bottom 33a in the direction of the storage container 32. The bottom 33a has a through-portion 33b. A ventilation valve 35 for ventilating the storage container 32 is arranged in the through-portion 33b. The ventilation valve 35 has two flexible lips 35a, 35b. When the cleaning liquid is taken out during the operation of the pressure cleaning system 10, a negative pressure is generated in the storage container 32. Due to the pressure difference generated relative to the surrounding environment, the ventilation valve 35 is opened by spacing the flexible lips 35a, 35b from each other. The pressure difference is compensated by the air flowing into the storage container 32. If pressure compensation is established, the ventilation valve 35 is closed. The flexible lips 35a, 35b then come into contact with each other. This is particularly caused by Figure 8 It can be seen that the recess 33 can be closed by means of a cover 37 , so that the ventilation valve 35 is protected from external influences, such as dirt.

[0044] The container unit 14 has a first container side 38 and a second container side 40 facing away from the first container side 38. The first container side 38 is inclined obliquely in the direction of the second container side 40. The distance between the first container side 38 and the second container side 40 increases in the insertion direction 16. The device receptacle 18 for the pressure cleaning device 12 is arranged on the first container side 38 of the container unit 14. The region 42 of the pressure cleaning device 12 protrudes from the device receptacle 18 of the container unit 14 when the pressure cleaning device 12 is in the inserted position.

[0045] Furthermore, the container unit 14 has a first wheel 44 and a second wheel 46 as well as a first foot 48 and a second foot 50. The wheels 44, 46 are mounted rotatably about a common rotation axis 47. In the standing position of use, the pressure cleaning system 10 stands with the wheels 44, 46 and the feet 48, 50 on a standing surface (not shown in the figure).

[0046] The container unit 14 has a push frame 52, which is designed in a U shape. The push frame 52 has a first arm 54 and a second arm 56, which are connected to each other by a crossbeam 58. The push frame 52 can be Figures 1 to 6 The first arm 54 is movably supported in the first guide channel 60, and the second arm 56 is movably supported in the second guide channel 62.

[0047] To move the pressure cleaning system 10, the operator can transition the push frame 52 from its retracted position to its extended position and tilt the pressure cleaning system 10 about the rotation axis 47, thereby lifting the feet 48, 50 from the standing surface. The operator can now transport the pressure cleaning system 10 by moving the wheels 44, 46, for example, the operator can push or tow the pressure cleaning system 10 depending on the type of cart.

[0048] A groove 66 is arranged on the storage container underside 64 of the container unit 14 facing the standing surface. To lift the pressure cleaning system 10, the operator can hold the crossbar 58 of the push frame 52 in its retracted position with one hand and reach into the groove 66 with the other hand.

[0049] At the second container side 40 of the container unit, the container unit 14 has a storage space 68. The storage space 68 can be used to store accessories.

[0050] In order to releasably fasten the pressure cleaning device 12 in the device receptacle 18 of the container unit 14 , the pressure cleaning system 10 has a fastening device 70 .

[0051] The pressure cleaning device 12 has a device front side 76 and a device rear side 78 facing away from the device front side 76, which in the inserted position of the pressure cleaning device 12 faces away from the second container side 40 of the container unit 14. The device front side 76 has a lower section 72 and an upper section 74 with respect to the vertical use position of the pressure cleaning system 10. The device front side 76 and the device rear side 78 are connected to each other via a first longitudinal side 80 and a second longitudinal side 82. In the inserted position of the pressure cleaning device 12, the first longitudinal side 80 and the second longitudinal side 82 each have a side section 81, 83 extending from the device receptacle 18 of the container unit 14. In addition, the pressure cleaning device 12 has a device upper side 84 pointing upwards and a device lower side 86 pointing downwards in the vertical use position.

[0052] The device inlet 26 is arranged at the device underside 86 of the pressure cleaning device 12. A connecting element 88 of the pressure cleaning device 12 is connected to the device inlet 26, which connecting element can be detachably connected to a liquid conveying line 89 of the container unit 14 that is sunken into the storage container 32. For this purpose, the connecting element 88, when the pressure cleaning device 12 is in the inserted position, is sunken into a connecting receiving element 90, which is arranged at the bottom 92 of the device receptacle 18 of the container unit 14 and is in flow connection with the liquid conveying line 89.

[0053] The device outlet 30 is arranged at the lower section 72 of the device front side 76 of the pressure cleaning device 12 at the region 42 that projects out of the device receptacle 18 when the pressure cleaning device 12 is in the inserted position. For example, a pressure hose can be connected to the device outlet 30, via which the cleaning liquid under pressure can be conveyed to a liquid discharge device, such as a spray gun or a spray bar, which is known per se and is therefore not shown for the sake of clarity.

[0054] A first accessory holder 94 is arranged on a side section 81 of the first longitudinal side 80 of the pressure cleaning device 12, which protrudes when the pressure cleaning device 12 is inserted, and a second accessory holder 95 is arranged on a side section 83 of the second longitudinal side 82 of the pressure cleaning device 12, which protrudes when the pressure cleaning device 12 is inserted. Accessories such as spray guns and / or spray lances can be detachably fastened to the accessory holders 94, 95.

[0055] In the inserted position of the pressure cleaning device 12, a first depression 96 is arranged below the first accessory holder 94 and a second depression 97 is arranged below the second accessory holder 95 on the first container side 38 of the container unit 14. Accessories arranged on the accessory holders 94, 95 can be supported on the bottoms 96a, 97a of the depressions 96, 97, respectively.

[0056] A battery 98 for supplying energy to the motor 22 can be inserted in a removable manner into a battery receptacle 100 . The battery receptacle 100 is arranged on the device upper side 84 of the pressure cleaning device 12 .

[0057] The pressure cleaning device 12 has a gripping member 102, which is arranged at the device front side 76 of the pressure cleaning device 12 at the region 42 that protrudes in the inserted position of the pressure cleaning device 12. In order to insert the pressure cleaning device 12 into the device receptacle 18 of the container unit 14, an operator can grasp the gripping member 102 and insert the pressure cleaning device 12 into the device receptacle 18 of the container unit 14 in the insertion direction 16. In order to remove the pressure cleaning device 12 from the device receptacle 18 of the container unit 14, an operator can grasp the gripping member 102 and remove the pressure cleaning device 12 from the device receptacle 18 of the container unit 14 in the opposite direction of the insertion direction 16. In addition, the pressure cleaning device 12 can be grasped at the gripping member 102 and transported in its released position.

[0058] With reference to the upright usage posture of the pressure cleaning system 10 , a switch 104 for switching the pressure cleaning device 12 on and off is arranged above the grip 102 .

[0059] In order to operate the pressure cleaning system 10, the operator can first fill the storage container 32 with cleaning liquid, such as water, via the injection nozzle 36. In order to move the pressure cleaning system 10 to the use site, the operator can move the push frame 52 from its retracted position to its extended position, then tilt the pressure cleaning system 10 around the rotation axis 47, so that the legs 48, 50 are lifted from the standing surface, and the pressure cleaning system 10 is dragged on the wheels 44, 46 behind the operator, for example. When arriving at the use site, the operator can convert the pressure cleaning system 10 into its upright use posture. The operator can now connect the pressure hose stored in the storage space 68, for example, to the device outlet 30. Accessories such as spray guns and spray rods that can be arranged at the accessory holders 94, 95 for transportation can be connected to the pressure hose. In order to clean a surface or object in particular, the cleaning liquid is delivered to the pump 24 from the storage container 32 by means of the liquid delivery line 89 via the device inlet 26. The pump 24 puts the cleaning liquid under pressure. The cleaning liquid can be output to the surface or object to be cleaned via the device outlet 30 and the pressure hose connected thereto and the liquid output mechanism. As long as there is cleaning liquid in the storage container 32, cleaning can be performed for a long time. When there is further cleaning demand, the cleaning liquid can be refilled into the storage container 32.

[0060] However, it is also possible to operate the pressure cleaning device 12 with an external supply of cleaning liquid. For this purpose, the operator can transfer the pressure cleaning device 12 from its insertion position to its release position by holding the pressure cleaning device 12 at the grip 102 and removing it from the device receptacle 18 of the container unit 14 in the opposite direction of the insertion direction 16. An external liquid supply line, such as a suction hose or a garden hose, can now be connected to the device inlet 26. The cleaning liquid supplied to the pump 24 is put under pressure and can be discharged again to the surface or object to be cleaned via a pressure hose connected to the device outlet 30 and a liquid discharge mechanism connected to the pressure hose.
