Description

Technical Field

[0001] The present invention relates to a high-pressure cleaning device, which includes a housing having an upper side, two opposed longitudinal sides, and two opposed transverse sides, and a motor and a pump driven by the motor are arranged in the housing. The cleaning liquid pressurized by the pump can be sent out via a high-pressure hose. In addition, the high-pressure cleaning device further includes a winding device having a hose reel for winding the high-pressure hose; or further includes an accessory container for storing at least one accessory of the high-pressure cleaning device. Background Art

[0002] With such a high-pressure cleaning device, the cleaning liquid, preferably water, can be pressurized by a motor-driven pump and sent out via a high-pressure hose.

[0003] The high-pressure cleaning device can have a winding device having a hose reel for winding the high-pressure hose. In a design scheme using such a high-pressure cleaning device, the user is provided with the possibility of unwinding the required length of the high-pressure hose from the hose reel in order to direct the pressurized cleaning liquid onto the surface to be cleaned. When not in use, the user can wind the high-pressure hose onto the hose reel again. Such a high-pressure cleaning device is known to those skilled in the art, for example, from EP 0 904 855 A2.

[0004] The high-pressure cleaning device can have an accessory container instead of a winding device, and at least one accessory of the high-pressure cleaning device can be stored in the accessory container. The accessory can be, for example, a nozzle, and the user can attach the nozzle to the free end of the high-pressure hose. Here, it is advantageous that there are a plurality of different nozzles available for the user, and these nozzles can be stored in the accessory container, and the user can connect one of the nozzles to the free end of the high-pressure hose according to different usage purposes.

[0005] Generally, using a winding device requires a design scheme in which the high-pressure cleaning device is specifically adapted to the winding device, but it is difficult to modify the high-pressure cleaning device to use an accessory container. Summary of the Invention

[0006] Therefore, the object of the present invention is to improve the high-pressure cleaning device of the generic type such that the high-pressure cleaning device can be optionally equipped with a winding device or accessories in a simple and inexpensive manner.

[0007] According to the present invention, in the high-pressure cleaning device of the type described at the beginning, this object is solved in that the housing has a receiving chamber open in the direction of the transverse side and the upper side in the transition region between the transverse side and the upper side, and at least the lower part of the winding device or the accessory container can optionally be inserted into the receiving chamber from above and can be releasably latched in the receiving chamber without tools.

[0008] The high-pressure cleaning device according to the invention has a receiving chamber in the transition region between the lateral side of the housing (for example, the rear side of the housing) and the upper side of the housing, and the receiving chamber is open in the direction of the lateral side (i.e., for example, in the direction of the rear side) and in the direction of the upper side. Since the receiving chamber is positioned in the transition region between the lateral side and the upper side of the housing, the receiving chamber is easily accessible so that at least the lower part of the winding device or also the accessory container can be inserted into the receiving chamber from above. The winding device can be releasably latched into the receiving chamber without tools, which means that latching can be carried out without using tools and can be released again if necessary. Instead of the winding device, the accessory container inserted into the receiving chamber can also be releasably latched in the receiving chamber without using tools. Thus, the assembly of the winding device or the accessory container is made very simple.

[0009] For example, it can be provided that in the manufacturing plant of the high-pressure cleaning device, the accessory container is inserted into the receiving chamber and releasably latched. If the user wishes to equip the high-pressure cleaning device with a winding device, the user can remove the accessory container from the receiving chamber without using special tools and assemble the winding device by, for example, inserting at least the lower part of the winding device into the winding chamber and releasably latching it without using special tools. Providing a receiving chamber into which at least the lower part of the winding device or also the accessory container can be inserted allows for mass production and thus inexpensive production of high-pressure cleaning devices, where either the winding device or the accessory container can already be assembled in the manufacturing plant, or alternatively, the user can modify the high-pressure cleaning device at a later time.

[0010] In a preferred design of the invention, the high-pressure cleaning device is designed to be movable, and for this purpose has a chassis on which a plurality of rollers, for example two runners rotatable about a common axis of rotation, are rotatably supported. It is also advantageous that at least one swivel wheel is rotatably supported on the chassis.

[0011] Particularly advantageously, the high-pressure cleaning device has a fuel-operated heat exchanger in addition to a motor-driven pump for heating the cleaning liquid pressurized by the pump.

[0012] In an advantageous embodiment of the present invention, the receiving chamber has two mutually opposed chamber side walls, on which guiding means are respectively arranged for guiding the winding device or the accessory container when the winding device or the accessory container is optionally inserted into the receiving chamber. The guiding means facilitates the insertion of the winding device and the accessory container into the receiving chamber. In particular, it can be provided that the guiding means is configured and designed to prevent the winding device or the accessory container from tilting when inserted into the receiving chamber.

[0013] Preferably, the winding device has two bearing parts, wherein the hose reel is arranged between the two bearing parts and is supported on the bearing parts in a rotatable manner about the reel axis, and wherein each of the bearing parts has at least one guiding element on its outer side facing away from the hose reel, and when at least the lower part of the winding device is inserted into the receiving chamber, the at least one guiding element cooperates with the guiding means arranged at the chamber side wall. In such an embodiment, the two bearing parts of the winding device accommodate the hose reel therebetween, and the hose reel is supported on the bearing parts in a rotatable manner about the reel axis. Each of the bearing parts has at least one guiding element on its outer side facing away from the hose reel, and when at least the lower part of the winding device is inserted into the receiving chamber, the at least one guiding element cooperates with the guiding means arranged at the chamber side wall of the receiving chamber.

[0014] In an advantageous embodiment of the present invention, at least one guiding element is designed as a guiding projection, and the guiding means cooperating with the at least one guiding element preferably has a guiding receiving part, and when at least the lower part of the winding device is inserted into the receiving chamber, the guiding projection sinks into the guiding receiving part. In such an embodiment of the present invention, at least one guiding projection is respectively arranged at the mutually opposed outer sides of the two bearing parts, and when at least the lower part of the winding device is inserted into the receiving chamber, the at least one guiding projection cooperates with the corresponding guiding receiving part of the receiving chamber.

[0015] Advantageously, the carrier part has two guide protrusions on its outer side facing away from the hose reel, which are designed as bolt-shaped and arranged at a distance from each other. When at least the lower part of the winding device is inserted into the receiving chamber, the first guide protrusion can first sink into the assigned guide receptacle, and then, when at least the lower part of the winding device is further inserted, the second guide protrusion can also sink into the assigned guide receptacle. These two guide protrusions arranged at a distance from each other facilitate the assembly of the winding device and, in addition, 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 is inserted into the receiving chamber. When the high-pressure hose is unwound from the hose reel, the tensile forces that the winding device may be subjected to will be absorbed by the two guide protrusions arranged on the outer side of the carrier part, so that the winding device does not perform a tilting movement despite the influence of the tensile force.

[0016] In order to additionally simplify the assembly of the winding device on the receiving chamber, in a preferred design of the present invention, the two guide protrusions are rigidly connected to each other via a guide rib, and when at least the lower part of the winding device is inserted into the receiving chamber, the guide rib sinks into the guide receptacle. In this design, the guide receptacle of the guide device arranged at the chamber side wall of the receiving chamber accommodates both the two guide protrusions and the guide rib. This facilitates the insertion of at least the lower part of the winding device into the receiving chamber, and during the insertion, the winding device is protected from accidental tilting.

[0017] In a particularly preferred design of the high-pressure cleaning device according to the present invention, the guide receptacles arranged at the chamber side walls of the receiving chamber are each designed as guide slots. When at least the lower part of the winding device is inserted into the receiving chamber, the assigned guide protrusion can be inserted into the guide slot. The guide slot can extend in the insertion direction, so that the guide protrusion can move along the guide slot during the assembly of the winding device.

[0018] Preferably, the guide devices arranged at the chamber side walls each have two mutually parallel guide rails, and the guide slot is arranged between the two guide rails. The guide rails can be designed to be mirror-symmetrical to each other and define the guide slot therebetween.

[0019] As described at the beginning, at least the lower part of the winding device can be inserted into the receiving chamber without tools and can be latched with the receiving chamber without tools. In an advantageous design of the present invention, the releasable latching is achieved in such a way that the winding device can be releasably locked with at least one chamber wall of the receiving chamber.

[0020] Particularly advantageously, the winding device can be releasably locked with the chamber bottom wall of the receiving chamber.

[0021] In an advantageous embodiment of the present invention, the winding device has at least one locking hook on its lower side facing the chamber bottom wall of the receiving chamber. When the winding device is in the assembled state, the at least one locking hook penetrates the notch in the chamber bottom wall. When at least the lower part of the winding device is inserted into the receiving chamber, the locking hook arranged on the lower side of the winding device faces the chamber bottom wall and penetrates the notch in the chamber bottom wall in the assembled state of the winding device. In the locked state, the locking hook can engage the notch from behind and lock the winding device in this way.

[0022] Advantageously, the lower side facing away from the chamber bottom wall of the receiving chamber is accessible to the user, so that in order to disassemble the winding device, the user can grasp the end region of the locking hook protruding from the chamber bottom wall from the lower side and move it to the release position, in which the locking hook does not engage the notch from behind. Subsequently, the user can lift the winding device upwards in order to remove the winding device from the receiving chamber.

[0023] In a particularly preferred embodiment, the winding device has a return spring, wherein the return spring can rotate the hose reel to automatically wind the high-pressure hose. When unwinding the high-pressure hose from the hose reel, the return spring loads the hose reel with a spring-elastic restoring force, and under the action of the restoring force, the hose reel can be rotated for winding the high-pressure hose.

[0024] Advantageously, the winding device includes a blocking mechanism by means of which the hose reel can be locked and the hose reel can be unlocked by briefly applying a tensile force to the unwound high-pressure hose. Such a return spring and a blocking mechanism are known from the published document WO 2019 / 206395 A1.

[0025] For the purpose of facilitating the operation of the winding device, it is advantageous that the winding device has a hose guiding part with a guiding opening through which the high-pressure hose can be guided, wherein the hose guiding part protrudes from the receiving chamber. By means of the hose guiding part, the high-pressure hose can be guided during winding and unwinding in order to ensure undisturbed winding and unwinding on the hose reel. Guiding the high-pressure hose during winding and unwinding is facilitated by the fact that the hose guiding part protrudes from the receiving chamber.

[0026] Advantageously, the guiding opening is delimited by freely rotatable guide rollers surrounding the guiding opening in the circumferential direction. The use of freely rotatable guide rollers enables the high-pressure hose to be guided almost unobstructed.

[0027] Advantageously, the receiving chamber is arranged in the transition region between the rear side and the upper side of the housing, wherein the hose guiding part protrudes from the receiving chamber towards the rear side.

[0028] The high-pressure cleaning device according to the invention has an inlet for conveying the pressurized cleaning liquid, and the high-pressure cleaning device according to the invention has an outlet for discharging the pressurized cleaning liquid. Advantageously, the winding device has a connecting hose for releasably connecting the outlet to the hose connection of the hose reel. The pressurized cleaning liquid can be conveyed to the hose reel via the connecting hose, so that the pressurized cleaning liquid can be directed onto the surface to be cleaned via the high-pressure hose arranged at the hose reel. If the high-pressure cleaning device is not equipped with a winding device but with the fitting container described at the beginning, the high-pressure hose can be directly connected to the outlet of the high-pressure cleaning device.

[0029] In an advantageous design of the invention, the fitting container that can be used instead of the above-mentioned winding device has two mutually opposed container side walls, which are respectively assigned to the chamber side walls of the receiving chamber, wherein each of the container side walls has at least one guiding element that cooperates with the guiding device arranged at the chamber side wall. In this design of the invention, the guiding devices arranged at the mutually opposed chamber side walls of the receiving chamber are used both for guiding the lower part of the winding device when at least the lower part of the winding device is to be inserted into the receiving chamber and for guiding the fitting container when the fitting container is to be inserted into the receiving chamber. When the fitting container is inserted into the receiving chamber, the guiding elements arranged at the mutually opposed side walls of the container will respectively cooperate with the guiding devices arranged at the chamber side walls.

[0030] In an advantageous design of the invention, at least one guiding element is designed as a groove-shaped recess of the container side wall. The groove-shaped recess can form, for example, a hem of the container side wall.

[0031] In an advantageous design of the invention, the receiving chamber has a chamber rear wall, at least one first guiding part is arranged at the chamber rear wall, and the fitting container has a container rear wall assigned to the chamber rear wall, wherein at least one second guiding part that is complementary to the at least one first guiding part is arranged at the container rear wall. When the fitting container is inserted into the receiving chamber, the at least one first guiding part located at the chamber rear wall cooperates with the complementary second guiding part arranged at the container rear wall. This helps to insert the fitting container into the receiving chamber.

[0032] In an advantageous design of the invention, at least one first guiding part is constructed as a guiding rib, and at least one second guiding part is advantageously constructed as a guiding slot. When the fitting container is inserted into the receiving chamber, the guiding rib sinks into the guiding slot.

[0033] Particularly advantageously, the accessory container can be closed by means of a lid, wherein the lid can be fastened to the receiving chamber in a tool-free and releasable manner and can be moved back and forth between a closed position and an open position. In this design of the present invention, after the accessory container is inserted into the receiving chamber, the lid can be fastened to the receiving chamber in a releasable manner, and the fastened lid can be moved back and forth between a closed position and an open position.

[0044] Embodiments of a high-pressure cleaning device according to the present invention are schematically shown in the drawings and are generally designated by the reference numeral 10. The high-pressure cleaning device 10 can optionally be equipped with a winding device 12 as described in detail below or with an accessory container 14 as described below, wherein the accessory container 14 can be closed by means of a lid 16. In Figures 1 to 6 a high-pressure cleaning device 10 equipped with a winding device 12 is schematically shown, and in Figures 7 to 9 a high-pressure cleaning device 10 equipped with an accessory container 14 and a lid 16 is schematically shown.

[0045] The high-pressure cleaning device 10 has a chassis 18. Two rear wheels are supported on the chassis 18 so as to be rotatable about a common axis of rotation 20, wherein only one rear wheel 22 is visible in the figure. In addition, a steering wheel 24 is rotatably supported on the chassis 18. By means of the rear wheels 22 and the steering wheel 24, the high-pressure cleaning device 10 can move along Figure 2 the placement surface 26 shown in

[0046] 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 a motor, pump, and heat exchanger are already known to those skilled in the art and will not be described in detail here. Figure 2 The motor 30, the pump 32, and the heat exchanger 34 are schematically shown in dashed lines in

[0047] The housing 28 has two longitudinal sides 36, 38 opposite one another, as well as a front transverse side (hereinafter referred to as the front side 40) and a rear transverse side (hereinafter referred to as the rear side 42). In addition, the housing 28 also has an upper side 44.

[0048] Two handles 46, 48 that project beyond the upper side 44 are arranged on the rear side 42. Two cable hooks 50, 52 are arranged below the handles 46, 48.

[0049] In particular, it can be clearly seen from Figures 4 to 6 and Figure 8 that the housing 28 has a receiving chamber 54 in the transition region between the rear side 42 and the upper side 44, which receiving chamber is delimited by a first chamber side wall 56, a second chamber side wall 58, a chamber bottom wall 60, and a chamber rear wall 62 and is open at the rear side and the upper side. Optionally, the lower part 64 of the winding device 12 or the accessory container 14 can be placed in the receiving chamber 54 and locked in the receiving chamber 54 in a releasable manner.

[0050] The winding device 12 has a hose reel 66 and a first bearing part 70 and a second bearing part 72, wherein the high-pressure hose 68 can be wound onto the hose reel. The hose reel 66 is received between the first bearing part and the second bearing part, and the hose reel 66 is supported on the first bearing part and the second bearing part in a manner rotatable about a reel axis 74. The reel axis 74 is oriented parallel to the common rotational axis 20 of the rear wheels 22.

[0051] The hose reel 66 has a winding body (not shown in the figure) onto which the high-pressure hose 68 can be wound, and the winding body extends between a first side disk surface 76 and a second side disk surface 78 of the hose reel 66. A return spring and a locking element in the form of a helical spring are integrally formed in a known manner (not shown in detail in the figure) in the first side disk surface 76. Such a return spring and a locking element are known, for example, from the published document WO 2019 / 206395 A1. In order to unwind the high-pressure hose 68 from the hose reel 66, the user can pull the high-pressure hose 68, causing the hose reel 66 to rotate about the reel axis 74, wherein the return spring is stressed. If the user unwinds the desired length of the high-pressure hose, the user no longer pulls the high-pressure hose 68 any longer, thereby canceling the tensile load thereon. This will cause the locking element to automatically lock the hose reel 66. In order to wind the high-pressure hose onto the hose reel 66 again after using the high-pressure cleaning device 10, the user only needs to briefly pull the high-pressure hose 68. This will cause the locking element to release the hose reel 66 again and cause the hose reel to rotate in the opposite direction of the original rotation under the action of the return spring.

[0052] The winding device 12 also has a hose guiding part 80 which projects rearwardly from the receiving chamber 54 and has a guiding opening 82 bounded by a freely rotatable guide roller 84. The freely rotatable guide roller 84 surrounds the guiding opening 82 in the circumferential direction. For winding and unwinding, the high-pressure hose 68 can be guided through the guiding opening 82, wherein the freely rotatable guide roller 84 ensures that the high-pressure hose 68 is hardly hindered by the guiding part 82.

[0053] The winding device 12 has a connecting hose 86 which can be detachably connected to a hose connection 88 of the winding device 12 and can be connected to an outlet 90 of the high-pressure cleaning device 10. Through this outlet, the cleaning liquid pressurized by the pump 32 can be discharged. The outlet 90 is arranged beside the inlet 92 at the rear side 42. Through the inlet, the cleaning liquid pressurized by the pump 32 can be supplied to the high-pressure cleaning device 10. For this purpose, a supply line, such as a suction hose, can be connected to the inlet 92.

[0054] For the purpose of facilitating the assembly of the winding device 12 into the receiving chamber 54, a first guiding device 94 is arranged at the first chamber side wall 56, and a second guiding device 96 is arranged at the second chamber side wall 58. This can be seen particularly clearly from Figure 4 , Figure 5 and Figure 6 . The two guiding devices 94, 96 are of the same design and each have two guide rails 98, 100 that are oriented parallel to each other, and the two guide rails define a guiding receptacle in the form of a guiding gap 102 therebetween. With respect to the horizontal use position of the high-pressure cleaning device 10 shown in the figure, the guiding gaps 102 of the two guiding devices 94, 96 extend in the vertical direction. The two bearing parts 70, 72 of the winding device each have guiding elements in the form of two bolt-shaped first guiding protrusions 108 and bolt-shaped second guiding protrusions 110 that are arranged spaced apart from each other on their outer sides 104, 106 facing away from the hose reel 66, and the two guiding elements are rigidly connected to each other via a guiding rib 112. When the lower part 64 of the winding device 12 is inserted into the receiving chamber 54, first the guiding protrusions 108 arranged at the outer sides 104, 106 of the bearing parts 70, 72, then the guiding rib 112, and finally the second guiding protrusion 110 can sink into the guiding gap 102, so that the winding device 12 is guided in the vertical direction by the two guiding devices 94, 96. This particularly ensures that the winding device 12 does not tilt when being assembled into the receiving chamber 44.

[0055] The chamber bottom wall 60 of the receiving chamber 54 has notches at a relatively small distance from the lower ends facing the chamber bottom wall 60 of the two guiding devices 94, 96, wherein Figure 4 and Figure 8 only the notch 114 arranged at a relatively small distance from the first guiding device 94 can be seen respectively. Second notches of the same design are arranged at a relatively small distance from the second guiding device 96. The first bearing part 70 of the winding device 12 has an elastically deformable first locking hook 118 at its lower side 116 facing the chamber bottom wall 60 of the receiving chamber 64, and the second bearing part 72 of the winding device 12 has an elastically deformable second locking hook 122 at its lower side 120 facing the chamber bottom wall 60 of the receiving chamber 54. From Figure 5 and Figure 6This can be seen particularly clearly. When the lower part 64 of the winding device 12 is inserted into the receiving chamber 54, the first locking hook 118 penetrates through the first notch 114 in the chamber bottom wall 60, and the second locking hook 122 penetrates through the second notch in the chamber bottom wall 60. In the inserted position of the winding device 12, the two locking hooks 118, 122 engage with the notches in the chamber bottom wall 60 from behind, that is to say, these two locking hooks occupy the locking positions, so that the winding device 12 is latched in the receiving chamber 54. Therefore, the lower part 64 of the winding device 12 can be inserted into the receiving chamber 54 and latched without using tools. If the winding device 12 is to be removed from the receiving chamber 54 again, it is only necessary to move the ends of the elastically deformable locking hooks 118, 122 protruding from the lower side of the chamber bottom wall 60 from their locking positions to the release positions, in which the locking hooks no longer engage with the chamber bottom wall 60 from behind, so that the winding device 12 can then be lifted and removed from the receiving chamber 54, and no tools are required for removing the winding device 12 from the receiving chamber 54 either. In order to move the locking hooks 118, 122 from their locking positions to their release positions, the user can touch the chamber bottom wall 60 from below at the rear side 42.

[0056] After the lower part 64 of the winding device 12 is inserted 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 the cleaning liquid pressurized by the pump 32 can subsequently be conveyed via the outlet 90 and the connecting hose 86 to the high-pressure hose 68 wound around the hose reel 66, in order to direct the pressurized cleaning liquid onto the surface to be cleaned via the high-pressure hose 68.

[0057] As described above, instead of the lower part 64 of the winding device 12, the accessory container 14 can also be inserted into the receiving chamber 54. From Figure 8 and Figure 9 This can be seen particularly clearly. 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 to each other. In addition, the accessory container 14 also 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 to the container rear wall 130. With respect to the horizontal use position of the high-pressure cleaning device 10, 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.

[0058] For facilitating the insertion of the accessory container 14 into the receiving chamber 54, a first guiding element 134 is arranged at the first container side wall 124, and a second guiding element 136 is arranged at the second container side wall 126. These two guiding elements 134, 136 are each designed as a groove-shaped recess in a crimp type. When the accessory container 14 is inserted into the receiving chamber 54, the groove-shaped first guiding element 134 receives the first guiding device 94 of the receiving chamber 54, and the second guiding element 136 receives the second guiding device 96 of the receiving chamber 54. When the accessory container 14 is inserted into the receiving chamber 54, the guiding elements 134, 136 slide along the guiding devices 94, 96.

[0059] The insertion of the accessory container 14 into the receiving chamber 54 is further simplified in such a way that two first guiding parts 138, 140 arranged spaced apart from each other on the chamber rear wall 62 cooperate respectively with the second guiding parts 142 or 144 arranged at the container rear wall 130 when the accessory container 14 is inserted into the receiving chamber 54. The second guiding parts 142, 144 are complementary to the first guiding parts 138, 140 in design. In the illustrated preferred embodiment, the first guiding parts 138, 140 each form a guiding groove, and the second guiding parts 142, 144 each form a guiding groove complementary to a guiding rib.

[0060] The container bottom wall 128 has two elastic locking hooks (not shown in the figure) on its lower side in a corresponding manner to the two bearing parts 70, 72 of the receiving chamber 54. When the accessory container 14 is inserted into the receiving chamber 54, these two elastic locking hooks penetrate through the notch arranged at the chamber bottom wall 60 and engage the notch 114 from behind in the insertion position of the accessory container 14, so that the accessory container 14 is latched in the receiving chamber 54. If the user wants to remove the accessory container 14 from the receiving chamber 54 again, the user can move the end of the locking hook extending from the lower side of the container bottom wall 128 from its locking position to its release position, in which the locking hook no longer engages the chamber bottom wall 60 from behind, so that the accessory container 14 can then be lifted and removed from the receiving chamber 54.

[0061] As described above, the accessory container 14 can be closed by means of the lid 16. After the accessory container 14 has been inserted into the receiving chamber 54, the lid 16 can be fastened to the upper edge of the chamber rear wall 62 without tools and, if necessary, can also be removed from the chamber rear wall 62 again without the use of tools.
