Definitions

  • the invention relates to a mobile high-pressure cleaning device with a motor and a pump driven by the latter, which are surrounded by a housing.
  • High-pressure cleaning devices often have relatively large motors and pumps, so that overall heavy devices result. In order to be able to transport these, it is known to make such cleaning devices mobile. Usually a chassis is used, on which the motor and the pump are placed directly, then a hood is placed on the chassis, which covers the motor and pump.
  • a mobile high-pressure cleaning device of the type described at the outset in that it comprises a chassis with a handle on which a shell-shaped housing part is arranged upright and open towards one side face, that the shell-shaped housing part has the motor and the pump in upright position that a lid on the open side of the housing part this can be closed and the motor and the pump can be placed surrounding it and that retaining elements on the motor and / or pump engage between the shell-shaped housing part and the cover such that the housing part and cover in the closed state fix the motor and pump in the housing formed from the housing part and cover.
  • a shell-shaped housing part is thus arranged on the chassis so that its interior is open to one side.
  • the motor and pump are inserted from the open side and fixed in this position in that a cover is placed on this cabinet-shaped chamber, in such a way that the cover and housing part together between the holding elements of the motor and / or pump fix.
  • recesses are arranged in the lateral edges of the shell-shaped housing part, into which the holding elements on the motor and / or pump engage.
  • These recesses can be arranged in the wall of the shell-shaped housing part, but in a preferred embodiment it can be provided that radially projecting flanges adjoin the lateral edges of the shell-shaped housing part, into which the recesses extend at least over part of the width of the flanges. These depressions are then themselves denform and extend in the laterally projecting flanges over a certain width.
  • Recesses can also be arranged in the lateral edges of the cover, into which the holding elements on the motor and / or pump engage. According to a preferred development, these depressions can also be located in radially projecting flanges which project radially from the lateral edges of the cover.
  • the shell-shaped housing part and the cover are connected to one another next to the depressions, for example by screws arranged next to the depressions.
  • the holding elements can be held in the recesses between the shell-shaped housing part and the cover in a press fit.
  • the depressions can be semicircular in cross section, for example.
  • the holding elements are arms which project laterally from the motor and / or the pump. According to a particularly preferred embodiment, it is provided that the holding elements dip into the depressions with the interposition of a rubber-elastic material, so that vibration and noise-damping mounting can be achieved in this way.
  • a rubber stopper can be attached to laterally protruding arms on the motor and / or pump.
  • the housing consisting of a shell-shaped housing part and cover essentially has the shape of a circular cylinder. This housing fits tightly around the electric motor and therefore takes up little space.
  • the housing consisting of a shell-shaped housing part and cover is arranged with its longitudinal axis between the support points of the chassis.
  • These bases of the chassis can be formed by wheels or by wheels and fixed supports, and these bases are usually arranged so that the chassis rests on them stably. If the longitudinal axis of the housing is arranged between these support points, this leads to the large weight of the motor and the pump being evenly distributed over the support points, so that the chassis is stable despite the high weight. This is also important in order to absorb the starting torque in an upright arrangement of the electric motor caused by the support points the ground must be transferred to avoid twisting the chassis.
  • the weight distribution can also be favorably influenced in that the longitudinal axis of the housing is slightly inclined with respect to the vertical. This not only allows the position of the center of gravity to be shifted slightly between the support points, but also results in better accessibility to the shell-shaped housing part, since this is arranged at a slightly inclined position. Finally, this inclination also contributes to the fact that, in the case of an appropriately inclined electric motor, the starting torque transmitted to the chassis and rotating it about the vertical axis is reduced.
  • the chassis has two juxtaposed wheels in the manner of a puncturing cart at its rear end, at least one support at its front end and the handle directed upwards at the rear end.
  • a chassis can be moved and parked like a handcart, and the bowl-shaped housing part is integrated into this handcart.
  • the handle is U-shaped with two arms and a handle part connecting them and that the shell-shaped housing part protrudes between the arms of the handle.
  • the housing is preferably inclined towards the rear of the handle. It is advantageous if the parting plane of the shell-shaped housing and the cover lies approximately in the middle of the housing, this parting plane preferably runs parallel to the longitudinal axis of the housing.
  • the motor and the pump are arranged one behind the other in the direction of the longitudinal axis of the housing. This results in a relatively slim arrangement, the motor pump unit thus formed is inserted upright into the housing, the axis of the motor being arranged substantially vertically, possibly slightly inclined in accordance with the inclination of the housing.
  • the housing may have vents on the top and bottom, and the motor may carry a fan wheel that promotes airflow through the housing.
  • ventilation openings can be partially covered, but it is also possible for the ventilation openings to arise simply by the housing being open at one end, for example on the lower side, through which the ventilation flow exits.
  • laterally projecting deflection elements are arranged on the outlet side of the air flow. are net, which prevent a direct backflow of the air flow along the outside of the housing to the inlet side of the air flow. This ensures that the air flow is not simply a cycle, but that the heated air that is released is scattered into the surroundings.
  • deflecting elements are molded onto the cover.
  • the cover can additionally have an opening through which an oil reservoir of the pump passes. In this way it is possible to check the oil level in this oil reservoir outside of the housing.
  • the cover carries a chamber for receiving electrical switching and connecting elements.
  • the housing is covered by an outer cover which runs at a distance from the cover.
  • this can give the device a pleasing appearance
  • technical elements on the outside of the housing for example a chamber for electrical elements, pipe connections, etc., can be covered.
  • the cover on the side of the bowl-shaped device part of the house is formed by a liquid tank for holding chemicals.
  • This liquid tank can be detachably held on the chassis.
  • liquid tank extends over the entire width of the chassis and lies flat against the outside of the shell-shaped housing part.
  • this liquid tank has a dual function, namely on the one hand it covers the housing from the outside and on the other hand it supplies the device with a voluminous, removable liquid tank.
  • Figure 1 is a longitudinal sectional view of the chassis of a high pressure cleaning device without a cover, without a lid and without a motor pump unit;
  • Figure 2 is a front view of the chassis of Figures 1 and
  • Figure 3 is a sectional view taken along line 3-3 in Figure 2 in a high-pressure cleaning device with a motor pump unit, with a lid and with a cover attached.
  • the high-pressure cleaning device shown in the drawing comprises a chassis 1 with a base plate 2, on the rear edge of which two wheels 3 and on the front edge of which a central support 4 are arranged.
  • the chassis 1 carries a U-shaped handle 5 projecting upwards with two parallel arms 6 and 7, which are connected to one another at their upper end via a crossbar, not shown in the drawing.
  • the arms 6 and 7 are arranged on the sides of the chassis 1, so that overall the chassis 1 is designed in the manner of a hand truck, as used for example for the transport of bottle crates.
  • a shell-shaped housing part 8 is arranged on the base plate 2, which has essentially the shape of a half circular cylinder and which is open towards the front.
  • the longitudinal axis of this semi-cylindrical housing part 8 is arranged to run essentially vertically, this longitudinal axis being slightly inclined to the rear at the upper end, ie in the direction of the handle 5. This inclination can be of the order of up to 25 °.
  • the semi-cylindrical housing part 8 is open on the underside, and on the top side it has a closed cover plate 9 with a central air inflow opening 10 which is covered by a hood 11.
  • Two recesses 16, 17 with a semicircular cross section are machined into these flanges 14 and 15 at a distance from one another, the longitudinal axis of these recesses 16 extending transversely to the longitudinal axis of the housing part 8.
  • the depressions 16 and 17 are in direct connection with the interior of the housing part 8.
  • Screw holes 18 are arranged in the flanges 14 and 15 on both sides of the depressions 16 and 17.
  • the housing part 8 is formed in one piece with the chassis 1, for example in the form of a plastic injection-molded part.
  • a cover 19 can be placed on the housing part 8 from its open front side.
  • This like the housing part 8, has the shape of a half circular cylinder with laterally projecting flanges 20 and recesses 21 and 22 arranged therein, which are arranged such that when the cover 19 is placed on the housing part 8, the recesses 16 and 17 with the recesses 21 and 22 are aligned and each form circular cylindrical openings in the side wall of the housing consisting of housing part 8 and cover 19.
  • screw holes 23 are arranged, which are aligned with the screw holes 18 of the housing part 8.
  • the cover 19 is partially closed on its upper end face by a cover plate 24, but it is open in the central area, so that this open part together with the air inflow opening 10 of the housing part enables an air flow to enter the housing.
  • the cover 19 is also open on the underside and thus allows the air flow to escape.
  • the cover 19 In its lower part, the cover 19 has a window-like opening 26 opposite the housing part 8, at the upper end the cover 19 carries a closed chamber 27 which serves to hold electrical parts, for example supply lines, connecting elements and switching elements.

  • This motor pump unit with the fan wheel is arranged in the housing so that the fan wheel 29 is arranged on the top immediately next to the air inflow opening 10, the pump at the lower end below the motor.
  • the motor pump unit 28 carries laterally projecting arms 30, on which rubber plugs 31 are attached. The arms 30 with the rubber plugs 31 rest in the recesses 16, 17 or 21 and 22, so that the motor pump unit 28 is thereby fixed in position inside the housing.
  • the motor pump unit 28 is simply inserted into the open housing part 8, so that the rubber plugs 31 are inserted into the recesses 16 and 17. Subsequently, the cover 19 is put on, the recesses 21 and 22 overlap the rubber plugs 31 located in the recesses 16 and 17.
  • the cover 19 and the housing part 8 are connected to one another by screws which are guided through the screw holes 18 and 23. By screwing the cover and the housing part together, the rubber plugs 31 are clamped in the recesses 16, 17 and 21, 22 and thereby fixed.
  • Housing part 8 and cover 19 are arranged so that the longitudinal axis of the motor pump unit 28 essentially is arranged between the support points which are formed by the wheels 3 and the support 4, ie the center of gravity of this motor pump unit lies approximately in the middle between these support points. Due to the inclination of the longitudinal axis of the housing and thus also the longitudinal axis of the motor pump unit 28, there is a certain amount of latitude for the shift of the center of gravity; the inclination of the center of gravity can be shifted as desired.
