Definitions

  • the invention relates to a high-pressure cleaning device having a wheel Chassis, with a trough-shaped lower part, with a motor pump unit and with a liquid container.
  • Such mobile high-pressure cleaning devices are usually on a metallic chassis mounted on which individual units in as possible favorable arrangement to be attached.
  • DE 38 23 320 A1 describes a high-pressure cleaning device of the generic type described in which the chassis by a trough-shaped lower part of a Outer housing is formed on which the wheels are mounted. On the a cover is placed on the trough-shaped lower part, and this outer housing then surrounds essential units of the high-pressure cleaning device including a liquid container that runs over a filler neck is accessible from the outside. So there are separate parts for the liquid container and necessary for the chassis, also need fasteners for the motor pump unit and possibly other units be present inside the outer case.
  • the liquid container consists of the trough-shaped lower part and a lid-shaped upper part, the along their congruent, superimposed front edges are interconnected that the wheels are mounted on the liquid container are so that the liquid container and the wheels together the chassis form, and that the motor pump unit on the outside of the liquid container is held.
  • the liquid container takes on the function in this construction of the frame or chassis by placing the wheels directly on the liquid container be stored and by storing the liquid container also forms for the motor pump unit. Metallic frames become thereby unnecessary.
  • Liquid containers for such devices are common relatively complicated, and therefore is the manufacture of such liquid containers difficult.
  • the liquid containers consist of two parts, namely a trough-shaped lower part and a lid-shaped one Top, which are shaped so that their front edges are congruent. In the area the lower and upper parts of these end edges lie against each other and are close together in this area connected. This makes it possible to do even very complicated ones geometric shapes of the liquid containers too realize that will be necessary when the liquid container the chassis function in the manner described should take over.
  • liquid container through inner walls of the trough-shaped lower part and the lid-shaped top, which is also longitudinal their congruent end edges with each other are connected in separate containers is divided.
  • the Liquid containers the most diverse liquid stocks can record next to each other, for example Cleaning chemicals, cleaning water, oil and the like.
  • a container by two identical covers clashing parts are formed can, as a simple blow molded part would be such a container no longer producible.
  • the welding is a mirror weld. That means a weld where the colliding Front edges by the interposition of a flat Heating element heated to softening and then after Removal of the flat heating element assembled under pressure become. With this technique one can Reach welding in the front edge area, namely along the entire leading edge contact area in the same Wise.
  • this support beam in a recess of the bottom of the trough-shaped lower part his.
  • the carrier with the trough-shaped Lower part is connected by tie rods, for example, by bolts that are trough-shaped Reach through the lower part and the support bracket.
  • the tie rod in one Area of the trough-shaped lower part, the between two adjacent outer walls of the trough-shaped lower part is arranged.
  • the tie rod thus does not end in the interior of the liquid container, but in an area outside the liquid container, which is defined by neighboring outer walls becomes.
  • the liquid container surrounds an opening, in which a boiler is arranged.
  • the opening goes completely through the liquid container through, so that the boiler is not on the Liquid container itself rests.
  • the wall of the liquid container keep a distance from the boiler. This ensures that the boiler not directly on all sides with the liquid container comes into contact, so that here a thermal contact is avoided.
  • This carrier can be made of one material poor heat conduction exist, so that this too Way is guaranteed that only a small amount of the boiler Transfer heat to the liquid container become.
  • This carrier can open the opening in the liquid container bridge diametrically. It is convenient if this carrier at the same time a support beam for stabilization of the lower part.
  • the lid-shaped upper part is a trough-shaped Recess to accommodate the motor pump unit having.
  • This depression is bowl-shaped and picks up the motor pump unit that is in it be fixed by suitable fasteners can.
  • the depression in the lid-shaped upper part and the hood attached to the motor pump unit forming a flow path for a cooling medium surrounded, for example for cooling air.
  • the top of the liquid container and the attached hood also take on the task of training a flow path for a cooling medium, so that none additional flow channels must be provided.
  • a flow channel is formed, in which air is led to a heater. Also in this case, this flow channel through the Walls of the lid-shaped upper part itself formed, see above that no additional lines for the burner air are necessary.
  • both are tub-shaped lower part as well as the lid-shaped Upper part in the area of the front edges at least the outside Double-walled walls. This stabilizes the liquid container in the area of Front edges, in addition, the double-walled area in a preferred embodiment, a circumferential Form the bumper.
  • the high-pressure cleaning device shown in the drawing comprises a closed liquid container 1 from a trough-shaped lower part 2 and a lid-shaped Top 3.
  • the trough-shaped lower part 2 is in a partial area annular and surrounds with an inner wall 5 a through opening 4, in the annular portion 6 a plurality of transverse walls 7 are arranged, which the annular section 6 in separate chambers 8 divide.
  • the bottom 9 of the trough-shaped lower part 2 has in its center is a groove-shaped one running in the longitudinal direction Indentation 10 in which a metal side member 11 is inserted, which reinforces the bottom 9.
  • This side member 11 is with bolts 12 connected to the trough-shaped lower part 2.
  • This Bolts 12 pass through the bottom 9 of the trough-shaped Lower part 2 in an area that is separated from the chambers 8 by transverse walls 13 ( Figure 1), i.e. these bolts 12 do not occur the interior of the trough-shaped lower part 2.
  • This chassis is completed by the cover-shaped Upper part 3, which is the trough-shaped lower part 2 closes on the top.
  • the upper part points to this 3 outer walls 16, inner walls 17 and transverse walls 18 on, in the region of their front edges 20 with the front edges 21 of the respective walls of the lower part 2 with the same cover run.
  • these end edges 20 and 21 meet the lower part 2 butt together, over the entire length all walls.
  • lower part 2 and upper part 3 connected to each other, for example by welding or a glue. Is particularly cheap in this context a so-called mirror welding.
  • the upper part 3 is contoured so that in the area the bolt 12 through openings 22 in the upper part 3 are provided through which the bolts are inserted can be.
  • This from liquid container 1, side members 11 and Wheels 14, 15 existing chassis serves as storage for a motor pump unit 26 which in itself known an electric motor, a high pressure pump and optionally includes a ventilation fan.
  • This motor pump unit 26 is in a cross section semicircular, bowl-shaped recess 27 in lid-shaped upper part 3 and is added by a Covered hood 28, the motor pump unit 26th encloses together with the recess 27 on all sides.
  • the Hood 28 is in turn designed as a closed container, 29 components used in its interior can be, for example, electrical and electronic Components.
  • the recess 27 and the hood 28 partially surround the motor pump unit 26 in the Distance and thereby form a flow channel, can flow through the cooling air that the motor pump unit 26 cools. This is done, for example, by a fan wheel from below through an opening in the liquid container 1 sucked in and then into the interior of a issued hood-shaped housing, which the device overlaid at the top.
  • Another fan wheel can be used in this way preheated air is sucked in and then via a flow channel 30 the boiler 31 in the form of combustion air are fed. Again, it is beneficial if parts of the blower housing and the flow channel 30 in the lid-shaped upper part 3 are molded.
  • a boiler 31 is arranged on the side member 11 rests and is carried by this.
  • the liquid container 1 surrounds the boiler 31 in Distance, so that an immediate thermal contact is avoided.
