Definitions

  • the invention relates to a high-pressure cleaning device with a high-pressure pump arranged in a housing, a liquid supply, a pressure line for the liquid conveyed by the high-pressure pump and with a chemical suction device which sucks a chemical from a storage container via an suction line, which is arranged in the housing.
  • High-pressure cleaning devices are also known, in which a chemical container is provided in the device itself, which can be filled via a filling opening, for example by means of a funnel. This is a cumbersome process where chemical is often spilled.
  • a high-pressure cleaning device of the type described at the outset in that a compartment which can be closed by means of a cover is arranged in the housing, in which there is a removable chemical container, that the chemical container has an opening which can be closed with a removable cover, that the suction line leads to the Cover penetrates and dips into the interior of the container and that the container is releasably held on the cover.
  • a completely independent chemical container which can be tightly closed by means of the lid is thus arranged in a special compartment.
  • this compartment is opened, the empty chemical container can then be removed from the compartment after removing the lid and either refilled outside the device or replaced by a previously filled chemical container.
  • Refilling is much easier than when refilling a permanently installed container using a funnel. For example, storage bottles etc. supplied by a chemical manufacturer can be used directly. Nevertheless, it is ensured that the chemical container inside the device is tightly closed by the lid, so that the high-pressure cleaning device can be operated without difficulty even when pivoting or lying down.
  • the container is releasably held on the cover, because only by opening or removing the cover it is possible in this way to remove the chemical container from the high-pressure cleaning device and to make it accessible so that it can be removed from the Cover can be easily removed for refilling.
  • the chemical container can be held on the cover, for example by a snap connection or by a tensioning device, for example a tensioning strap.
  • an air supply valve is arranged in the lid, which ensures a pressure equalization in the interior of the container when the chemical is removed from the storage container.
  • an opening in the lid through which the suction line passes is provided with valve-like sealing lips which allow air to enter the container from the environment, but seal the container interior against the liquid from escaping to the outside.
  • the seal in the lid opening through which the suction line passes also simultaneously takes on the function of a valve that can only be opened in the direction of the interior of the container, but not in the opposite direction.
  • the container is transparent at least in some areas and a window is arranged in this area of the cover. In this way, a filling level check is possible from the outside of the housing.
  • the window can be a slot-shaped opening in the cover, into which the container dips with a projection.
  • the container is designed as a blow molded part.
  • a portable and mobile high-pressure cleaning device 1 comprises in a housing 2 a high-pressure pump, not shown in the drawing, with a liquid supply and a high-pressure line delivering the conveyed liquid, which feeds the conveyed liquid, for example to a high-pressure spray lance or the like.
  • a compartment 3 On the inside of the housing 2 there is a compartment 3 on one side, which is closed off by a cover 4.
  • the cover 4 is designed to be removable, for example it can be hinged like a door, or the cover 4 is designed as a slide-in module and is releasably held in the inserted position by magnets or other holding elements.
  • the cover 4 has on the underside a shelf 5 projecting vertically into the compartment 3, on which a container 6 rests.
  • This container 6 essentially fills the entire lower part of the compartment 3. It is made as a blow molding container from plastic, preferably from transparent plastic, and is completely closed except for an opening 7 on the top.
  • the opening 7 at the top is at the end of a filler neck 8, a lid 9 is placed on the opening 7.
  • the container 6 is detachably held on the cover 4, for example by means of an elastic latching connection, not shown in the drawing, or by means of a tensioning strap.
  • a vertical, slot-shaped opening 10 is arranged in the cover 4, which forms a window through which the container 6 can be seen. At least in this area, the container is made transparent, in this way it is possible to look into the interior of the container and to monitor the respective fill level in the container.
  • the container is bulged in the area of the opening 10 and engages with this bulge 11 in the opening 10. On the one hand, this means that the container is fixed in the compartment against lateral displacement, and on the other hand, filling level monitoring is made easier.
  • the removable cover 9, which closes the container 6, has an opening 12 through which a suction hose 13 is guided, which carries a sieve or filter 14 at its free end.
  • the suction hose 13 is so deeply immersed in the container 6 that the chemical filled in the container can be sucked into the bottom area.
  • the suction hose 13 leads to an injector, in which a negative pressure is generated, in a manner not shown in the drawing.
  • the chemical sucked in via the suction hose 13 is added to the liquid conveyed by the high-pressure pump, so that the high-pressure cleaning device releases a cleaning liquid mixed with chemicals when the chemical is sucked in.
  • the suction hose 13 is usually sealed against the lid 9, in this case there is an air inlet valve 15 in the cover 9, through which air from the environment can enter the interior of the container as soon as the pressure inside is lower than in the environment. In contrast, this valve prevents liquid from escaping from the inside of the container.
  • the opening 12 can be sealed off from the suction hose 13 by means of a sealing lip 16 which can be elastically bent inwards, so that air can also enter the interior of the container via this seal. To the outside, however, this sealing lip 16 cannot be bent, so that liquid from the interior of the container cannot pass to the outside via this sealing lip, which acts as a valve.
  • the container 6 can now be refilled at any point. It is also possible to replace the container. To do this, it is removed from the cover and replaced with a filled container.
  • the device is then put together again in the reverse manner, that is to say the suction hose 13 and the sieve 14 are introduced into the container, the lid 9 is placed in a sealing manner and the container and the cover 4 are pushed into the compartment 3.
  • the container 6 is designed as a part separate from the cover 4.
  • the container itself represents the cover of the compartment.
  • the container is shaped accordingly, so that the outer wall of the container simultaneously forms a housing wall and in this way closes the compartment. It would also be possible that a corresponding cover is provided for the compartment, but that the container is not releasably connected to this cover, for example by being molded in one piece or by gluing.
