Description

[0001] HIGH-PRESSURE CLEANING DEVICE

[0002] The invention relates to a high-pressure cleaning device comprising a housing which has a top side and two mutually opposite longitudinal sides and two mutually opposite transverse sides and in which a motor and a pump driven by the motor are arranged, wherein cleaning fluid pressurised by the pump can be delivered via a high-pressure hose, and further comprising a winding device which has a hose reel for winding up the high-pressure hose, or an accessory container for storing at least one accessory part of the high-pressure cleaning device.

[0003] By means of such a high-pressure cleaning device, a cleaning liquid, preferably water, can be pressurized by means of the motor-driven pump and released via the high-pressure hose.

[0004] The high-pressure cleaning device can have a winding device with a hose reel for winding the high-pressure hose. With such a high-pressure cleaning device configuration, the user has the option of unwinding a desired length of the high-pressure hose from the hose reel to direct the pressurized cleaning fluid onto a surface to be cleaned. When not in use, the user can rewind the high-pressure hose onto the hose reel. Such high-pressure cleaning devices are known to those skilled in the art, for example, from EP 0 904 855 A2.

[0005] Instead of a winding device, the high-pressure cleaning device can have an accessory container in which at least one accessory of the high-pressure cleaning device can be stored. The accessory can be, for example, a spray nozzle that the user can attach to the free end of the high-pressure hose. It is advantageous if the user has several different spray nozzles available, which can be stored in the accessory container. The user can connect one of the spray nozzles to the free end of the high-pressure hose depending on the intended use.

[0006] Typically, the use of a winding device requires a design of the high-pressure cleaning device that is specifically adapted to the winding device, which makes it difficult to convert the high-pressure cleaning device for the use of an accessory container.

[0007] The object of the present invention is therefore to further develop a high-pressure cleaning device of the generic type in such a way that the high-pressure cleaning device can be equipped in a simple and cost-effective manner either with a winding device or with an accessory.

[0008] This object is achieved according to the invention in a high-pressure cleaning device of the type mentioned at the outset in that the housing has, in the transition area between a transverse side and the upper side, a receiving chamber which is open in the direction of the transverse side and the upper side and into which at least a lower part of the winding device or the accessory container can be inserted from above and can be releasably locked in the receiving chamber without the need for tools.

[0009] The high-pressure cleaning device according to the invention has a receiving chamber in the transition area between a transverse side of the housing, for example the rear of the housing, and the top of the housing, which receiving chamber is open towards the transverse side, for example towards the rear, and towards the top. Due to its positioning in the transition area between the transverse side and the top of the housing, the receiving chamber is easily accessible in order to insert at least a lower part of the winding device or the accessory container into the receiving chamber from above. The winding device can be releasably locked in the receiving chamber without the use of a tool, i.e. it can be locked without the use of a tool and can also be released again if necessary. Instead of the winding device, the accessory container inserted into the receiving chamber can also be releasably locked in the receiving chamber without the use of a tool.The installation of the winding device or alternatively the accessory container is therefore very easy.

[0010] For example, it may be provided that an accessory container is inserted into the receiving chamber at the manufacturer's factory and releasably locked. If a user wishes to equip the high-pressure cleaning device with a winding device, they can remove the accessory container from the receiving chamber without the use of a special tool and install the winding device by inserting at least a lower part of the winding device into the winding chamber and releasably locking it in place without the use of a special tool.The provision of a receiving chamber into which at least a lower part of a winding device or an accessory container can be inserted allows the high-pressure cleaning device to be produced in large quantities and thus cost-effectively, whereby either the winding device or the accessory container can be assembled in the manufacturer's factory, or the user can convert the high-pressure cleaning device at a later date.

[0011] In a preferred embodiment of the invention, the high-pressure cleaning device is designed to be movable and, for this purpose, has a chassis on which several wheels are rotatably mounted, for example, two running wheels rotatable about a common axis of rotation. Advantageously, at least one swivel castor is also rotatably mounted on the chassis.

[0012] It is particularly advantageous if the high-pressure cleaning device, in addition to the motor-driven pump, has a fuel-operated heat exchanger for heating the cleaning fluid pressurized by the pump. In an advantageous embodiment of the invention, the receiving chamber has two opposing chamber side walls, on each of which a guide device is arranged for selectively guiding the winding device or the accessory container during insertion into the receiving chamber. The guide devices facilitate the insertion of the winding device and the accessory container into the receiving chamber. In particular, it can be provided that the guide devices are arranged and designed to prevent the winding device or the accessory container from tipping during insertion into the receiving chamber.

[0013] The winding device preferably has two support parts, wherein the hose reel is arranged between the two support parts and mounted on the support parts for rotation about a reel axis. The support parts each have at least one guide element on their outer sides facing away from the hose reel, which interacts with a guide device arranged on a chamber side wall when at least the lower part of the winding device is inserted into the receiving chamber. In such a configuration, two support parts of the winding device accommodate the hose reel between them, which is mounted on the support parts for rotation about a reel axis.On their outer sides facing away from the hose reel, the support parts each have at least one guide element which, when at least the lower part of the winding device is inserted into the receiving chamber, cooperates with a guide device which is arranged on a chamber side wall of the receiving chamber.

[0014] In an advantageous embodiment of the invention, the at least one guide element is designed as a guide projection, and the guide device interacting with the at least one guide element preferably has a guide receptacle into which the guide projection engages when at least the lower part of the winding device is inserted into the receiving chamber. In such an embodiment of the invention, at least one guide projection is arranged on the opposite outer sides of the two support parts, which interacts with an associated guide receptacle of the receiving chamber when at least the lower part of the winding device is inserted into the receiving chamber.

[0015] It is advantageous if the support parts each have two guide projections on their outer sides facing away from the hose reel, which are designed in a peg-shaped manner and arranged at a distance from one another. When at least the lower part of the winding device is inserted into the receiving chamber, a first guide projection can initially be inserted into a guide receptacle assigned to it, and when at least the lower part of the winding device is further inserted, the second guide projection can then also be inserted into the assigned guide receptacle. The two guide projections, which are arranged at a distance from one another, facilitate the assembly of the winding device and, moreover, have the function of preventing the winding device from tilting when the high-pressure hose is unwound from the hose reel after at least the lower part of the winding device has been inserted into the receiving chamber.When unwinding the high-pressure hose from the hose reel, the winding device can be subjected to a tensile force which is absorbed by the two guide projections, each arranged on an outer side of a supporting part, so that the winding device does not perform a tilting movement despite the acting tensile force.

[0016] To further simplify the assembly of the winding device to the receiving chamber, in a preferred embodiment of the invention, the two guide projections are rigidly connected to one another via a guide rib, wherein the guide rib engages the guide receptacle upon insertion of at least the lower part of the winding device into the receiving chamber. In such a configuration, the guide receptacle of the guide device, which is arranged on a side wall of the receiving chamber, accommodates both the two guide projections and the guide rib. This facilitates the insertion of at least the lower part of the winding device into the receiving chamber, wherein the winding device is secured against unintentional tilting even during insertion.

[0017] In a particularly preferred embodiment of the high-pressure cleaning device according to the invention, the guide receptacles arranged on the side walls of the receiving chamber are each designed as a guide slot. The associated guide projection can be inserted into the guide slot when inserting at least the lower part of the winding device into the receiving chamber. The guide slot can extend in the insertion direction so that the guide projection can be moved along the guide slot during assembly of the winding device.

[0018] The guide devices, each arranged on a chamber side wall, preferably each have two parallel guide rails, between which the guide slot is arranged. The guide rails can be designed mirror-symmetrically to each other and define the guide slot between them.

[0019] As already mentioned at the beginning, at least the lower part of the winding device can be inserted into the receiving chamber without tools and can be locked to the receiving chamber without tools. In an advantageous embodiment of the invention, the releasable locking is achieved in such a way that the winding device can be releasably locked to at least one chamber wall of the receiving chamber.

[0020] It is particularly advantageous if the winding device can be releasably locked to a chamber bottom wall of the receiving chamber.

[0021] In an advantageous embodiment of the invention, the winding device has at least one locking hook on its underside facing the chamber bottom wall of the receiving chamber, which engages through an opening in the chamber bottom wall when the winding device is in the assembled state. When at least the lower part of the winding device is inserted into the receiving chamber, the locking hook arranged on the underside of the winding device faces the chamber bottom wall and, when the winding device is in the assembled state, engages through an opening in the chamber bottom wall. In the locked state, the locking hook can engage behind the opening and thus lock the winding device.

[0022] Conveniently, the underside of the chamber floor wall facing away from the receiving chamber is accessible to the user, allowing the user to grasp the end portion of the locking hook protruding from the underside of the chamber floor wall and move it into a release position in which the locking hook does not engage behind the opening. The user can then lift the winding device upward to remove it from the receiving chamber.

[0023] In a particularly preferred embodiment, the winding device has a return spring, whereby the hose reel can be rotated by the return spring for automatic winding of the high-pressure hose. When the high-pressure hose is unwound from the hose reel, the return spring applies a spring-elastic return force to the hose reel, under the action of which the hose reel can be rotated for winding up the pressure hose.

[0024] Advantageously, the winding device comprises a locking element, with which the hose reel can be locked and unlocked by briefly applying a tensile force to the unwound high-pressure hose. Such return springs and locking elements are known from publication WO 2019 / 206395 A1.

[0025] To facilitate handling of the winding device, it is advantageous if the winding device has a hose guide with a guide opening through which the high-pressure hose can be guided, with the hose guide protruding from the receiving chamber. The hose guide can be used to guide the high-pressure hose during winding and unwinding, ensuring smooth winding and unwinding on the hose reel. Guiding the high-pressure hose during winding and unwinding is made easier by the fact that the hose guide protrudes from the receiving chamber.

[0026] The guide opening is conveniently limited by freely rotating guide rollers that surround the guide opening circumferentially. The use of freely rotating guide rollers allows the high-pressure hose to be guided virtually unhindered.

[0027] Advantageously, the receiving chamber is arranged in the transition area between a rear side of the housing and the top side of the housing, with the hose guide part protruding from the rear side of the receiving chamber.

[0028] The high-pressure cleaning device according to the invention has an inlet for supplying pressurized cleaning fluid, and an outlet for discharging pressurized cleaning fluid. It is advantageous if the winding device has a connecting hose for detachably connecting the outlet to a hose connection of the hose reel. Pressurized cleaning fluid can be fed to the hose reel via the connecting hose, so that it can be directed onto a surface to be cleaned via the high-pressure hose arranged on the hose reel. If the high-pressure cleaning device is to be equipped not with the winding device but with the accessory container mentioned above, a high-pressure hose can be connected directly to the outlet of the high-pressure cleaning device.

[0029] In an advantageous embodiment of the invention, the accessory container, which can be used instead of the winding device explained above, has two opposing container side walls, each associated with a chamber side wall of the receiving chamber, wherein the container side walls each have at least one guide member that interacts with a guide device arranged on the chamber side wall. In such an embodiment of the invention, the guide devices arranged on the opposing chamber side walls of the receiving chamber serve, on the one hand, to guide the lower part of the winding device if at least the lower part of the winding device is to be inserted into the receiving chamber, and, on the other hand, to guide the accessory container if the accessory container is to be inserted into the receiving chamber.When inserting the accessory container into the receiving chamber, the guide members arranged on the opposite side walls of the container each interact with a guide device arranged on a side wall of the chamber.

[0030] In an advantageous embodiment of the invention, the at least one guide member is designed as a groove-shaped recess in the container side wall. The groove-shaped recess can, for example, form a bead in the container side wall.

[0031] In an advantageous embodiment of the invention, the receiving chamber has a chamber rear wall on which at least one first guide part is arranged, and the accessory container has a container rear wall that is assigned to the chamber rear wall, wherein at least one second guide part designed complementarily to the at least one first guide part is arranged on the container rear wall. When inserting the accessory container into the receiving chamber, the at least one first guide part, which is positioned on the chamber rear wall, interacts with a complementarily designed second guide part, which is arranged on the container rear wall. This facilitates inserting the accessory container into the receiving chamber.

[0032] In an advantageous embodiment of the invention, the at least one first guide part is designed as a guide rib, and the at least one second guide part is advantageously designed as a guide groove into which the guide rib dips when the accessory container is inserted into the receiving chamber.

[0033] It is particularly advantageous if the accessory container is closable by means of a lid, wherein the lid can be releasably attached to the receiving chamber without the need for tools and can be moved back and forth between a closed position and an open position. With such an embodiment of the invention, after the accessory container has been inserted into the receiving chamber, a lid can be releasably attached to the receiving chamber, wherein the attached lid can be moved back and forth between a closed position and an open position.

[0034] The following description of an advantageous embodiment of the invention serves to explain it in more detail in conjunction with the drawings. They show:

[0045] The drawing schematically illustrates an advantageous embodiment of a high-pressure cleaning device according to the invention and is designated overall by the reference numeral 10. The high-pressure cleaning device 10 can optionally be equipped with a winding device 12, explained in more detail below, or with an accessory container 14, explained in more detail below, wherein the accessory container 14 can be closed by means of a lid 16. Figures 1 to 6 schematically illustrate the high-pressure cleaning device 10 with the winding device 12, and Figures 7 to 9 schematically illustrate the high-pressure cleaning device 10 with the accessory container 14 and the lid 16.

[0046] The high-pressure cleaning device 10 has a chassis 18. Two rear wheels are mounted on the chassis 18 for rotation about a common axis of rotation 20, although only one rear wheel 22 is visible in the drawing. Furthermore, a swivel caster 24 is mounted on the chassis 18 for rotation. Using the rear wheels 22 and the swivel caster 24, the high-pressure cleaning device 10 can be moved along a base 26 shown in Figure 2.

[0047] The high-pressure cleaning device also has a housing 28 in which a motor 30, a pump 32 driven by the motor 30, and a fuel-operated heat exchanger 34 are arranged. Such motors, pumps, and heat exchangers are known per se to those skilled in the art and therefore require no further explanation here. The motor 30, the pump 32, and the heat exchanger 34 are shown schematically in dashed lines in Figure 2.

[0048] The housing 28 has two opposing longitudinal sides 36, 38, as well as a front transverse side, referred to below as the front side 40, and a rear transverse side, referred to below as the rear side 42. Furthermore, the housing 28 has a top side 44.

[0049] Two handles 46, 48 are arranged on the rear side 42, projecting above the top side 44. Two cable hooks 50, 52 are arranged below the handles 46, 48.

[0050] As is particularly clear from Figures 4 to 6 and 8, the housing 28 has a receiving chamber 54 in the transition area between the rear side 42 and the top side 44. The receiving chamber 54 is bounded by a first chamber side wall 56 and a second chamber side wall 58, as well as by a chamber bottom wall 60 and a chamber rear wall 62, and is open at the rear and top. A lower part 64 of the winding device 12 or the accessory container 14 can be inserted into the receiving chamber 54 and releasably locked in the receiving chamber 54.

[0051] The winding device 12 has a hose reel 66 onto which a high-pressure hose 68 can be wound, as well as a first support member 70 and a second support member 72, which accommodate the hose reel 66 between them and on which the hose reel 66 is rotatably mounted about a reel axis 74. The reel axis 74 is aligned parallel to the common rotation axis 20 of the rear wheels 22.

[0052] The hose reel 66 has a winding body (not shown in the drawing) onto which the high-pressure hose 68 can be wound and which extends between a first side panel 76 and a second side panel 78 of the hose reel 66. A return spring in the form of a spiral spring and a locking member are integrated into the first side panel 76 in a known manner, which is therefore not shown in detail in the drawing. Such return springs and locking members are known, for example, from the publication WO 2019 / 206395 A1. To unwind the high-pressure hose 68 from the hose reel 66, the user can pull on the high-pressure hose 68, causing the hose reel 66 to rotate about the reel axis 74, tensioning the return spring. Once the user has unwound the desired length of high-pressure hose, they no longer pull on the high-pressure hose 68, so that its tensile load is removed.This results in the locking member automatically locking the hose reel 66. To rewind the high-pressure hose onto the hose reel 66 after use of the high-pressure cleaning device 10, the user simply needs to briefly pull on the high-pressure hose 68. This results in the locking member releasing the hose reel 66, and the hose reel 66 is rotated in the opposite direction to its original direction under the action of the return spring.

[0053] The winding device 12 also has a hose guide part 80 that projects out from the rear of the receiving chamber 54 and has a guide opening 82 that is delimited by freely rotatable guide rollers 84. The freely rotatable guide rollers 84 surround the guide opening 82 in the circumferential direction. For winding and unwinding, the high-pressure hose 68 can be guided through the guide opening 82, wherein the freely rotatable guide rollers 84 ensure that the high-pressure hose 68 is practically unhindered by the guide part 82. The winding device 12 has a connecting hose 86 that can be detachably connected to a hose connection 88 of the winding device 12 and that can be connected to an outlet 90 of the high-pressure cleaning device 10, via which the cleaning fluid pressurized by the pump 32 can be discharged. The outlet 90 is arranged on the rear side 42 next to an inlet 92.Cleaning fluid can be supplied to the high-pressure cleaning device 10 via the inlet 92, which fluid is to be pressurized by the pump 32. For this purpose, a supply line, for example a suction hose, can be connected to the inlet 92.

[0054] In order to facilitate the assembly of the winding device 12 on the receiving chamber 54, a first guide device 94 is arranged on the first chamber side wall 56 and a second guide device 96 is arranged on the second chamber side wall 58. This is particularly clear from Figures 4, 5 and 6. The two guide devices 94 and 96 are identically designed and each have two guide rails 98, 100 aligned parallel to one another, which define a guide receptacle in the form of a guide slot 102 between them. The guide slots 102 of the two guide devices 94, 96 extend in a vertical direction with respect to the horizontal position of use of the high-pressure cleaning device 10 shown in the drawing. The two support parts 70, 72 of the winding device have, on their outer sides 104 and 106 facing away from the hose drum 66,106 each have two guide elements arranged at a distance from one another in the form of a first pin-shaped guide projection 108 and a second pin-shaped guide projection 110, which are rigidly connected to one another via a guide rib 112. When inserting the lower part 64 of the winding device 12 into the receiving chamber 54, first the guide projections 108 arranged on the outer sides 104 and 106 of the support parts 70, 72, then the guide ribs 112 and finally the second guide projections 110 can enter the guide slots 102, so that the winding device 12 is guided in the vertical direction by the two guide devices 94, 96. This ensures, in particular, that the winding device 12 does not tilt during assembly on the receiving chamber 44.

[0055] The chamber bottom wall 60 of the receiving chamber 54 has an opening at a short distance from the lower ends of the two guide devices 94, 96 facing the chamber bottom wall 60. In Figures 4 and 8, only one opening 114 is visible in each case, which is arranged at a short distance from the first guide device 94. An identically designed second opening is arranged at a short distance from the second guide device 96. The first support part 70 of the winding device 12 has a first elastically deformable locking hook 118 on its underside 116 facing the chamber bottom wall 60 of the receiving chamber 64, and the second support part 72 of the winding device 12 has a second elastically deformable locking hook 122 on its underside 120 facing the chamber bottom wall 60 of the receiving chamber 54. This is particularly clear from Figures 5 and 6.When inserting the lower part 64 of the winding device 12 into the receiving chamber 54, the first locking hook 118 engages through the first opening 114 in the chamber bottom wall 60, and the second locking hook 122 engages through the second opening in the chamber bottom wall 60. In the inserted position of the winding device 12, the two locking hooks 118, 122 engage behind the openings in the chamber bottom wall 60, i.e., they assume a locking position, so that the winding device 12 is locked in the receiving chamber 54. The lower part 64 of the winding device 12 can thus be inserted and locked into the receiving chamber 54 without the use of a tool.If the winding device 12 is to be removed from the receiving chamber 54 again, it is merely necessary to move the ends of the elastically deformable locking hooks 118, 122 protruding from the underside of the chamber bottom wall 60 from their locking position into a release position in which they do not engage behind the chamber bottom wall 60, so that the winding device 12 can then be lifted and removed from the receiving chamber 54, whereby no tools are required for removing the winding device 12 from the receiving chamber 54. To move the locking hooks 118, 122 from their locking position to their release position, the user can reach under the chamber bottom wall 60 from the rear side 42.

[0056] After inserting the lower part 64 of the winding device 12 into the receiving chamber 54, it is only necessary to connect the connecting hose 86 to the outlet 90 of the high-pressure cleaning device 10, so that cleaning fluid which has been pressurized by the pump 32 can then be fed via the outlet 90 and the connecting hose 86 to the high-pressure hose 68 wound onto the hose reel 66 in order to direct the pressurized cleaning fluid via the high-pressure hose 68 onto a surface to be cleaned.

[0057] As already mentioned, instead of the lower part 64 of the winding device 12, the accessory container 14 can also be inserted into the receiving chamber 54. This is particularly clear from Figures 8 and 9. The accessory container 14 has a first container side wall 124 and a second container side wall 126. The two container side walls 124, 126 are opposite one another. In addition, the accessory container 14 has a container bottom wall 128 as well as a container rear wall 130 and a container front wall 132. The container front wall 132 is opposite the container rear wall 130. The container side walls 124, 126 as well as the container rear wall 130 and the container front wall 132 extend vertically upward from the container bottom wall 128 relative to a horizontal position of use of the high-pressure cleaning device 10.

[0058] To facilitate the insertion of the accessory container 14 into the receiving chamber 54, a first guide member 134 is arranged on the first container side wall 124, and a second guide member 136 is arranged on the second container side wall 126. The two guide members 134, 136 are each designed as a groove-shaped depression in the manner of a bead. When the accessory container 14 is inserted into the receiving chamber 54, the groove-shaped first guide member 134 receives the first guide device 94 of the receiving chamber 54, and the second guide member 136 receives the second guide device 96 of the receiving chamber 54. The guide members 134, 136 slide along the guide devices 94, 96 when the accessory container 14 is inserted into the receiving chamber 54.

[0059] Inserting the accessory container 14 into the receiving chamber 54 is further simplified by providing two first guide parts 138, 140 spaced apart from one another on the chamber rear wall 62. When inserting the accessory container 14 into the receiving chamber 54, these first guide parts each interact with a second guide part 142 or 144 arranged on the container rear wall 130. The second guide parts 142, 144 are designed to complement the first guide parts 138, 140. In the preferred embodiment shown in the drawing, the first guide parts 138, 140 each form a guide groove, and the second guide parts 142, 144 each form a guide groove complementary to the guide ribs.

[0060] The container bottom wall 128 has on its underside, in a similar manner to the two support parts 70, 72 of the receiving chamber 54, two elastic locking hooks (not shown in the drawing), which, when the accessory container 14 is inserted into the receiving chamber 54, engage through the openings arranged in the chamber bottom wall 60 and, in the inserted position of the accessory container 14, engage behind the openings 114, so that the accessory container 14 is locked in the receiving chamber 54. If the user wishes to remove the accessory container 14 from the receiving chamber 54, they can move the ends of the locking hooks protruding from the underside of the container bottom wall 128 from their locked position to their release position, in which they do not engage behind the chamber bottom wall 60, so that the accessory container 14 can then be lifted and removed from the receiving chamber 54. As already mentioned, the accessory container 14 can be closed by means of the lid 16.After inserting the accessory container 14 into the receiving chamber 54, the lid 16 can be fastened to the upper edge of the chamber rear wall 62 without the use of tools and, if necessary, can also be removed from the chamber rear wall 62 again without the use of tools. For this purpose, the lid 16 has two essentially U-shaped holding members 146, 148, each of which carries a pivot pin 150, 152 and can each be inserted into an opening 154 or 156 of the chamber rear wall 62 arranged at the upper edge of the chamber rear wall 62, wherein the pivot pins 150, 152 are each received by two joint half-shells (not shown in the drawing) arranged on the rear side of the chamber rear wall 62 facing away from the receiving chamber 54, next to the openings 154 and 156.The pivot pins 150, 152, in combination with the associated hinge half-shells, form a hinge so that the lid 16 can be moved back and forth between a closed position closing the accessory container 14 and a release position releasing the accessory container 14.

[0061] In the accessory container 14, accessories of the high-pressure cleaning device can be stored, for example several spray nozzles, whereby the user has the option of optionally connecting one of the spray nozzles to the free end of the high-pressure hose 68, for example a point jet nozzle, a flat jet nozzle or a rotor nozzle.
