Description

[0001] High-pressure cleaning device with hose reel

[0002] The present invention relates to a cleaning system, in particular a high-pressure cleaning system with a high-pressure cleaner, a hose and a hose reel.

[0003] High-pressure cleaners are used to clean surfaces. These draw water from a standard water pipe. The high-pressure cleaner typically features a booster unit to deliver a concentrated water jet. For improved handling and flexible use, a high-pressure cleaner often features a hose, allowing a high-pressure lance to be used flexibly and at variable distances from the booster unit for cleaning or surface treatment. The hose between the high-pressure lance and booster unit can typically be several meters long, allowing the largest possible area to be treated radially around the high-pressure cleaner.

[0004] Especially when the pressure washer is not in use or needs to be repositioned, the meter-long hose can make handling cumbersome or take up too much space. Especially since, in addition to the hose, a power cable and a water supply line are often connected to the pressure washer, this can lead to unwanted tangling or knotting of the lines. Improper handling can cause damage to the pressure washer's lines or other connection points.

[0005] The invention is therefore based on the object of integrating a device for simple and user-friendly handling of a high-pressure cleaning hose into a cleaning system in order to provide efficient and flexible use of a high-pressure cleaner.

[0006] The problem is solved by a device having the features of independent claim 1.

[0007] According to one aspect of the present invention, a cleaning system, in particular a high-pressure cleaning system, is provided, comprising a high-pressure cleaner, a hose and a hose reel, wherein the high-pressure cleaner has a motor, in particular an electric motor, and a pump driven by the motor, in particular an in-line pump, and a housing and a handling unit, wherein the hose is in fluid connection with the pump or can be brought into fluid connection with the pump, wherein the hose can be wound onto the hose reel, wherein the hose reel is fastened and / or mounted on the handling unit, in particular on two support supports, wherein the motor and / or the pump are preferably located outside the housing and / or in particular protrude from the housing.

[0008] The claimed device offers, among other advantages, that the user can prepare and dismantle the cleaning system for use in a particularly time- and space-saving manner. Because the hose can be wound onto the hose reel, it can be stowed not only quickly but also particularly carefully, allowing the entire cleaning system to be stored as integrally and space-savingly as possible, without the hose suffering any kinks or damage. The hose can also be unwound particularly quickly and easily, which additionally provides a variable operating radius around the high-pressure cleaner. Furthermore, the hose reel is compactly integrated into the high-pressure cleaner, allowing the high-pressure cleaner to be moved around for optimal handling and robustness against impacts.Furthermore, positioning the hose reel near the handling unit allows for easy yet efficient access to the hose. Furthermore, exposing the pump or motor allows for efficient cooling of these components. Furthermore, exposing the motor and / or pump allows the waste heat to be used, particularly for drying the hose or hose reel after use.

[0009] In a preferred embodiment, a high-pressure cleaner, in particular a pump, can be supplied with water supplied from a water pipe or a conventional water hose with normal water pressure. It is also conceivable for the high-pressure cleaner to have a suction nozzle that can suck in standing water and pump it into the high-pressure cleaner. A hose of the cleaning system is designed to be in fluid contact with the pump. The hose can have a fiber-reinforced or metal-mesh-reinforced sheath material surrounded by a flexible polymer layer, in particular a rubber layer.

[0010] This allows the hose to be tolerant of pressurization of the water to be pumped, whereby the water pressure can be generated via the pump and a motor connected to it. The motor can preferably be an electric motor, in particular a three-phase motor with a power consumption of at least 4 kW, preferably at least 5.5 kW, but in particular also an internal combustion engine. The motor can be connected and / or connectable directly to the pump via a shaft. The pump can be designed as an in-line pump so that larger quantities of water can be pumped. A rotary control can be arranged on the pump to regulate the pump's delivery pressure. This allows the performance of the cleaning system to be reduced or adjusted according to user specifications. Furthermore, a pressure display, in particular a pressure gauge, can be arranged on the pump so that the user can read the pump's delivery pressure and adjust it themselves.The high-pressure cleaner has a housing, which can comprise plastic, in particular can be a component produced by injection molding. The housing can protect the high-pressure cleaner from contamination and damage. For increased accessibility and / or to dissipate waste heat, the motor and / or the pump are arranged outside the housing, in particular in one or more recesses in the housing. Furthermore, the high-pressure cleaner has a handling unit, which can be designed in the form of a bracket, in particular as a bent tube. Two ends of the handling unit can be connected, in particular screwed and / or bolted, to the high-pressure cleaner, in particular to the housing of the high-pressure cleaner. As a result, forces applied to the handling unit can be introduced into the high-pressure cleaner, in particular into the housing.The handling unit can have two support supports running parallel to one another, which can be designed to hold or mount a rotatable hose reel. Additionally or alternatively, the hose reel can also be arranged and / or mountable on two holding elements, wherein these two holding elements are arranged and / or mountable, in particular screwable, on the support supports. It is also conceivable for the two holding elements to be arranged and / or mountable, in particular screwable, on the support supports indirectly via at least one intermediate element. This can increase a modular design and simplified interchangeability of individual components of the cleaning system. The holding elements can also be part of the hose reel. This can reduce the number of components of the cleaning system. Furthermore, the additional intermediate element can increase the rigidity of the handling unit.Additionally, a support can be arranged between the intermediate element and the handling unit, in particular in the handle area, to further increase the rigidity of the cleaning system. The hose can additionally or alternatively be connected to the pump of the high-pressure cleaner via the hose reel. In other words, the hose reel can have a coupling element which, in particular rotatably, connects the hose to the pump, in particular to an intermediate hose delivered by the pump. The hose reel can be made entirely or at least partially of plastic. Alternatively or partially, the hose reel can also be made of metal, in particular from several metal sheets, in order to have increased resistance to impacts and damage. The hose reel can be and / or can be rotatably mounted on the high-pressure cleaner, in particular on the handling unit or the holding elements.The hose reel can have two limiting surfaces that protrude radially from a rotational axis of the hose reel. These limiting surfaces can be designed to limit individual winding layers of the hose that can be wound onto the hose reel. The hose can be both wound onto and unwound from the hose reel, in particular by rotating the hose reel around the rotational axis.

[0011] Preferably, the support supports of the handling unit can be connected to one another by a handle area. In other words, the handling unit can have a curved tube with two parallel ends, with the handle area located between the two ends. The handle area can simplify manual relocation or shifting of the high-pressure cleaner, since the handle area extends, at least partially, beyond the high-pressure cleaner. The handle area can comprise one or more bends in the handling unit. Furthermore, the handle area can be coated with a plastic or rubber layer, thus making it easier to grip.

[0012] Preferably, the center of gravity of the high-pressure cleaner can be arranged such that the high-pressure cleaner can be operated in a standing or lying position. In other words, in a standing position, the center of gravity can lie between the rollers and a first support extension of the housing. In the lying position, the center of gravity can lie between the rollers and a second support extension of the housing. The first support extension differs in particular from the second support extension and can be designed as a base or several, in particular two, bases. The second support extension can be designed as a support surface or a lying surface. In particular, the center of gravity is at the position of the pump.

[0013] The hose can preferably have a coupling for a spray device, in particular a cleaning gun, at a distal end. The coupling can consist of a male coupling element and / or a female coupling element, wherein both coupling elements can be designed to be complementary to one another. Furthermore, both coupling elements can be separable from one another by means of a movable locking element. The female coupling element can be arranged and / or arrangeable at the distal end of the hose and the complementary male coupling element at the spray device, or vice versa. If both coupling elements engage with one another, they can be inseparable in a displacement direction normal to the coupling elements, but in particular can be rotatable about this displacement direction. This allows a compensating movement of a twisted hose to occur.The two coupling elements can be made of the same material, especially brass. This can provide increased corrosion resistance.

[0014] Preferably, two stop rods aligned parallel to one another can be attached to the cleaning system, in particular between the support supports of the handling unit, such that a gap or intermediate space is formed between the stop rods, wherein the hose is guided through the gap or intermediate space. This can guide the hose and untangle any possible twisting of the hose. Alternatively or additionally, this can also achieve controlled winding onto the hose reel. The stop rods can in particular be oriented orthogonally to the two support supports of the handling unit, in particular clamped and / or screwed to the support supports. This allows loads acting on the stop rods to be transmitted to the support supports.The two stop rods can be arranged parallel to one another, preferably offset from one another along the support posts, more preferably substantially one above the other when the cleaning system is in operation. This allows the hose end having the coupling to strike the two stop rods. It is also conceivable for the two stop rods, in particular one of the two stop rods, to be movable along the support posts. This allows the gap or space between the two stop rods to be variable. The gap can be smaller than the outer diameter of the coupling so that the hose cannot be pulled into the stop rods any further than the coupling, in particular cannot be wound onto the downstream hose reel. The hose can additionally or alternatively have an end stop element, which can be or is arranged in front of the coupling.This can alternatively or additionally limit the retraction of the hose. The stop rods can be made of metal or plastic, in particular injection-molded parts, in order to have increased tolerance to damage. Additionally or alternatively, the stop rods can be arranged between two stop rod holders instead of between the two support posts. The stop rod holders can in turn be arranged immovably on the two holding elements, which are in contact with the at least one intermediate element. This offers the advantage that the two stop rods can be flexibly positioned and, furthermore, different hose reel carriers can be integrated into a cleaning system.

[0015] Preferably, the stop rods can be arranged or arranged on stop rod holders, wherein the stop rod holders can be arranged or arranged on the holding elements. In other words, the stop rod holders can serve as an intermediate element to align the stop rods relative to the holding elements. In a broader sense, the position of the stop rods relative to the hose reel can be determined by the stop rod holders. These stop rod holders correspond in particular to the stop rod holders mentioned above. Thus, optimal winding or unwinding of the hose on the hose reel can be achieved.

[0016] Stop rod holders can preferably be arranged so as to be rotatable relative to the holding elements, in particular about the axis of rotation. In other words, the angular position between the stop rod holder and the holding elements is, in particular, variable. This can achieve the effect that the hose end or the coupling can be unwound or protruded from the high-pressure cleaner in different orientations. This makes it possible to optimally wind or unwind the hose in different positions (upright or lying) of the high-pressure cleaner. Additionally or alternatively, it is also conceivable for the stop rod holders and the holding elements to have a plurality of complementary bores. This allows the stop rod holders to be connected to the holding elements in various discrete angular positions.This can be achieved by having the hose end and / or the coupling protrude discreetly from the pressure washer, for example, from the front or from a top side offset from it. This allows the pressure washer to be adapted to different operating conditions.

[0017] Preferably, the stop rod holders can be formed sheet metal parts. This allows for particularly cost-effective production. Furthermore, the stop rod holders can have beads, edges, or folds. This increases the load-bearing capacity of the stop rod holders and, in particular, their torsion tolerance.

[0018] Preferably, stop rod holders can have a main extension direction, wherein the length in the main extension direction can be greater than or equal to an outermost diameter of the hose reel. In other words, the stop rod holders can extend beyond an outermost point of the hose reel, starting from holding elements. This can provide the effect that the stop rods on the stop rod holder can be arranged in such a way to the hose reel that the hose can be wound off or onto the hose reel tangentially, thus requiring particularly little force.

[0019] Preferably, the hose reel can be detachably connectable or connected to an intermediate element. More precisely, the holding elements of the hose reel can be detachably connectable or connected to the intermediate element. Detachable can be understood to mean a positive connection by clips, locking lugs, or shaped elements such as screws or rivets, so that the hose reel, in particular holding elements, is positively connected to the intermediate element in one state and detached therefrom in another state. The intermediate element can correspond to the intermediate element mentioned above. This offers the advantage of particularly good accessibility for maintenance and / or cleaning work. Furthermore, the interchangeability of hose reels of different types, characterized in particular by different hose length capacities, can be provided.

[0020] Preferably, rollers, in particular one roller each, can be provided on the stop rods, whereby the hose rolls or can roll off on the rollers. In contrast to fixed stop rods, stop rods provided with rollers can advantageously enable the hose to be knotted when unwinding and facilitated winding up. This makes the handling of the high-pressure cleaner considerably easier and more comfortable. The rollers can be made of metal or plastic, in particular have a soft, adaptable coating. This can increase the clamping effect of the two rollers on the hose. Furthermore, rotating rollers can facilitate the winding and / or unwinding of the hose on the hose reel.

[0021] Preferably, the rollers can each be mounted so as to be rotatable about a roller axis, wherein the roller axes are parallel to one another. The roller axes lie in particular on the two extension axes of the stop rods and / or describe or represent in particular a shortest distance between the two support posts. The roller axes are in particular parallel to the axis of rotation of the hose reel. The rollers can be arranged so as to be rotatable on the stop rods without intermediate elements and / or can surround the stop rods. This can reduce the component complexity. Alternatively or additionally, the rollers can be arranged so as to be rotatable on the respective stop rod by means of at least one bearing element. This can advantageously reduce the rolling resistance.

[0022] Preferably, the rollers can be guided along the roller axis in a form-fitting manner, in particular by the support supports, and / or the support supports can form a form-fitting stop for the rollers along the roller axis. In other words, a translational displacement of the rollers along the roller axis can be made more difficult and / or hindered, in particular limited, by the two support supports. In particular, the rollers can have a certain amount of play, in particular in a radial orientation, relative to the stop rods, so that they are mounted on the stop rods so as to be easily rotatable about the roller axis.

[0023] The high-pressure cleaner can preferably have support wheels, in particular two support wheels, wherein one of the support wheels, preferably all support wheels, is rotatable about a rotation axis. One, in particular all support wheels, can be designed so that the cleaning system can be moved, in particular rolled on the support wheels. This makes it possible to achieve particularly user-friendly movement or change of position of the cleaning system. The rotation axes of the two support wheels, in particular, can be oriented parallel to one another, preferably lying on top of one another. Furthermore, the rotation axes of the two support wheels, in particular, can be oriented parallel to the rotation axis of the hose reel. This makes it particularly easy to move the cleaning system. The support wheels can have a diameter of up to 400 mm, preferably between 120 mm and 360 mm, particularly preferably between 150 mm and 320 mm.A support wheel with a diameter of more than 400 mm rolls particularly well on muddy surfaces, while a support wheel in the second range can also roll well on flat surfaces. A support wheel in the third range can roll particularly smoothly on both muddy surfaces and flat surfaces with little resistance.

[0024] Preferably, an extension direction of the handle portion and a rotation axis of the hose reel can be parallel to one another and / or wherein the extension direction of the handle portion and / or the rotation axis of the hose reel can be parallel to the rotation axis and / or wherein the roller axis(es) can be parallel to the rotation axis and / or the rotation axis. Because the extension axis of the handle portion can be parallel to the rotation axis of the hose reel, the hose can be wound into the hose reel or unwound from the hose reel in a direction that is oriented normal to the rotation axis and / or the extension direction of the handle portion. This also makes it possible to define a front region along which the hose can be moved.The cleaning system can be moved along the hose's travel direction with particularly low resistance if the rotation axis is aligned parallel to the hose reel's rotation axis. Furthermore, in the configuration shown, the user can optimally reach the handle area with both hands, for example, to push the cleaning system along the at least one support wheel. Because the roller axis can also be oriented parallel to the rotation axis, the hose can be wound onto and unwound from the hose reel with reduced resistance. In other words, the hose can be optimally fed into the hose reel.

[0025] The motor can preferably have a three-phase connection. The cleaning system can be powered by standard household alternating current and / or, in particular, also by high-voltage current. A control and regulation unit can supply the motor with power via the three-phase connection, in particular with direct current, in order to rotate the motor in one direction of rotation, in particular depending on predefined settings. The level of power determined by the control and regulation unit and transmitted to the motor can influence the delivery rate and thus the delivery pressure of the pump downstream of the motor. In other words, the cleaning system can provide different water pressures to ensure the most flexible use possible.

[0026] The motor can preferably have a nominal speed in the range of 1200 to 1600 rpm, preferably 1400 rpm. The nominal speed of the motor is particularly proportional to the flow rate of the cleaning system pump located downstream of the motor. In the range between 1200 and 1600 rpm, both efficient operation of the cleaning system and increased water pressure can be provided. This allows for particularly flexible use of the cleaning system. At 1400 rpm, the cleaning system can operate particularly well-balanced and economically.

[0027] Preferably, the pump can have a delivery rate in the range from 900 l / h to 1400 l / h, in particular in the range from 980 l / h to 1250 l / h, and / or wherein the pump has a brass housing and / or wherein the pump is mounted on the motor. In the range from 900 l / h to 1400 l / h, a particularly flexible delivery rate can be provided by the pump. This means that such a pump can be used for a particularly wide variety of purposes, in particular for industrial cleaning or surface treatment work. In a range from 980 l / h to 1250 l / h, simplified control of the pump can be achieved because, in particular, the power consumption of the motor connected to the pump varies to a lesser extent than in the first range. Furthermore, the pump can comprise a brass housing, which is why the pump housing can have an increased tolerance to periodic pressure loads.The pump can be glued to the motor, preferably screwed, or glued and screwed. Additionally or alternatively, the motor and the pump can be connected and / or interconnected by at least one movable component, in particular a shaft. This allows a movement, in particular a rotational movement, of the motor to be transmitted to the pump.

[0028] The hose reel can preferably be an automatic hose reel. An automatic hose reel can be characterized in particular in that it does not require continuous external intervention to wind up the hose, e.g., by operating a hand crank. This allows the hose reel to wind up the hose wound onto it independently. During the unwinding of the hose, a spring or an alternative energy storage medium can be pre-tensioned or supplied with energy. This spring or alternative energy storage medium progressively relaxes or releases its energy, in particular, is energetically stabilized, as the hose is automatically wound onto the hose reel. Furthermore, the hose reel can be prevented from winding up the hose independently by means of a latching device.The locking device can be designed as a circumferential, in particular partially circumferential, toothing around the rotational axis of the hose reel and can have a plurality of teeth. An engagement element can be arranged, for example, on one of the holding elements or one of the support supports, in particular on a part that is immovable relative to the hose reel. The engagement element can be designed such that it engages with a tooth of the plurality of teeth in a direction of rotation of the automatic hose reel, in particular in the direction of unwinding the hose from the hose reel. So that the hose can be unwound from the automatic hose reel, the engagement element can be releasable from engagement with a tooth of the plurality of teeth.

[0029] Alternatively, the hose reel can have a crank for manual operation. The crank can have one operating end directly on the rotation axis of the hose reel. This allows the hose reel to rotate with one revolution of the crank. Furthermore, the crank can have a crank end that can be designed as a handpiece. This allows for particularly ergonomic actuation of the hose reel. Furthermore, the crank can have at least one bent joint. This allows the crank to be arranged on the hose reel in a particularly space-saving manner. Furthermore, the bent crank can inhibit the rotation of the hose reel around the rotation axis. This prevents a wound-up hose from unwinding itself from the hose reel.

[0030] Preferably, a spray device holding device can be arranged on the handling unit, in particular on one or both support supports, wherein the spray device holding device in particular allows insertion of the spray device longitudinally or parallel to the support support. The spray device holding device serves to temporarily hold a spray device, in particular a cleaning gun and / or a cleaning lance. The spray device holding device can be made of plastic or another material. In particular, the spray device holding device is designed to be glued and / or screwed to a support support.The spray device holding device can be designed such that it has a contour that is complementary to an outer shape of the spray device, in particular of the cleaning gun. Therefore, the spray device can engage positively in the spray device holding device and be held therein by means of a stop or a taper. The spray device holding device can be designed such that the spray device can be held, preferably oriented parallel along one of the two support supports. In addition, both support supports can each have a spray device holding device, in particular be in contact therewith. Furthermore, the spray device holding device can additionally or alternatively be designed such that the spray device can be held parallel to the support supports. This can provide a flexible storage space for the spray device.

[0031] Individual embodiments and features can be combined with other embodiments and other features to form new embodiments. The configurations and advantages of the embodiments and features also apply analogously to the new embodiments.

[0032] Embodiments of the present invention will be described in detail below with reference to the accompanying figures.

[0035] Fig. 3: A rear view of the cleaning system according to an embodiment of the present invention. In the figures, like features are identified by like reference numerals.

[0036] Fig. 1 shows a cleaning system 1, in particular a high-pressure cleaner 10, in an isometric view. A housing 16 forms a type of base body of the high-pressure cleaner 10, in which a motor 12 and a pump 14 are integrated, in particular screwed, in each case. The motor 12 and the pump 14 are connected to one another and can be regarded as a single unit which partially protrudes from the housing 16, in particular from a front side of the housing 16. The pump 14 further comprises a brass housing 15 on which a pressure gauge is arranged so that a delivery pressure of the pump 14 can be read by a user. Furthermore, the user can regulate the delivery pressure, in particular control a maximum pressure, via a rotary control arranged on the pump 14. The pump 14 further comprises a water connection with which the high-pressure cleaner 10 can be supplied with water.Furthermore, a handling unit 18 is arranged on the housing 16, which is in particular screwed, riveted or otherwise connected to the housing 16. The handling unit 18 is designed as a bent tube, of which two support supports 19 running parallel to one another can at least partially engage and / or be inserted into a recess or formation of the housing 16. The handling unit 18 has a handle area 20, in particular approximately in the middle of the bent tube. It is conceivable for the handling unit 18 to be designed in several parts, in particular for both support supports 19 to be connected to one another by the handle area 20. This can offer the advantage of a small packaging size and provide a particularly compact design of the cleaning system 1. In the embodiment shown in Fig. 1, two stop rods 22 are shown, each surrounded by a roller 24.In other words, a roller 24 can roll on a respective stop rod 22, in particular with some play. In the embodiment shown, the stop rods 22 are held by two stop rod holders 21, in particular screwed, riveted, or otherwise connected thereto. This can promote an optimized orientation of the stop rods 22 or the rollers 24 located thereon. In other words, the stop rods 22 are spatially oriented such that the stop rods 22 can be and / or are arranged in front of and / or on a hose reel 40. This allows a hose 30 to be guided through a gap between the stop rods 22 during winding onto or unwinding from the hose reel 40. The two stop rod holders 21 are furthermore in contact, in particular screwed, glued, or otherwise connected, with a respective holding element 23.The holding elements 23 are in turn arranged on an intermediate element 27, in particular screwed, glued, or connected in some other way. The intermediate element 27 is designed as a type of support platform, which is supported on a rear side by means of a support 26, in particular glued, screwed, or connected to the support 26 in some other way. The support 26 is additionally in contact with the handle area 20, in particular clamped, screwed, or connected in some other way. At the distal end of the hose 30, which protrudes in particular beyond the front of the high-pressure cleaner 10, a coupling 32 is arranged, which is designed, on the one hand, to fluidically communicate with a spray device 50, in particular a cleaning gun 52, and, on the other hand, to strike the stop rods 22. As a result, the retraction of the hose 30 can be limited, in particular by a positive fit.Furthermore, in the embodiment shown, the high-pressure cleaner 10 also has an additional stop, which is spaced from the distal end of the hose 30 and can strike the stop rods 22. The cleaning gun 52 can be inserted into, in particular arranged therein, a spray device holding device 54, wherein the spray device holding device 54 can be arranged, screwed, riveted, or connected in some other way to one of the two support posts 19. In the embodiment shown, a spray device holding device 54 is arranged on each support post 19. Furthermore, in the embodiment shown, the high-pressure cleaner 10 has two support wheels 28, which are arranged so as to be rotatable relative to the housing. The support wheels 28 can be rotated along a rotation axis 29. The rotation axis 29 is aligned parallel to a direction of extension E of the handle area 20.Furthermore, the hose reel 40 is rotatable about a rotation axis 34, wherein the rotation axis 34 is also aligned parallel to the extension direction E. Fig. 2 shows a frontal view, in particular a front view, of a high-pressure cleaner 10, in particular according to the same embodiment as shown in Fig. 1. Fig. 2 particularly shows the parallel alignments of the axes mentioned in Fig. 1. Accordingly, the extension direction E, the rotation axis 34, the two roller axes 25 and the rotation axis 29 are aligned parallel to one another. Furthermore, the motor 12 has a larger outer diameter than the pump 14 or the brass housing 15 arranged thereon, so that the motor 12 is visible in the frontal view and can be better ventilated.Additionally, a rotary switch, preferably a rotary control, more preferably an on / off switch, is arranged above the motor. This switch can be configured to regulate, in particular interrupt or connect, the power supply to the cleaning system 1. Furthermore, Fig. 2 shows the two spray device holders 54, each of which is arranged on one of the support brackets 19.

[0037] Fig. 3 shows a rear view of a high-pressure cleaner 10, in particular according to the same embodiment as shown in Figs. 1 and 2. In Fig. 3, the arrangement of the hose reel 40 and its mounting relative to the handling unit 18 is particularly clear. The intermediate element 27 serves as a support platform on which the two holding elements 23 are arranged, so that the hose reel 40, which is arranged thereon so as to be rotatable relative to the holding elements 23, is positioned approximately in the middle between the two support supports 19. In addition, the intermediate element 27 is connected via the support 26 to the handle area 20 of the handling unit 18, in particular is supported thereon. Furthermore, in Fig. 3, a power connection, in particular a high-voltage connection, is provided, via which the high-pressure cleaner 10 can be supplied with power.The power cable of the power connection can be wound onto designated retaining lugs, which in turn are arranged on one of the support supports, in particular glued, clamped, screwed, or otherwise secured. Furthermore, the rear of the motor 12 is shown in Fig. 3, which has impellers. This can provide the effect of supplying the motor 12 with fresh air for cooling during operation.
