Definitions

  • the invention relates to a pump unit with a housing according to the preamble of patent claim 1.
  • high-pressure pumps operated by electric motors are becoming increasingly popular.
  • a pump block is flanged to the electric motor in the direction of the horizontal axis of rotation, to which corresponding fittings connect.
  • the necessary switch box and a relatively large capacitor are also attached to the motor.
  • Such high-pressure pumps are used under harsh conditions, so that there is often damage, in particular to the switch box and the capacitor, but also to the fittings.
  • various elements are required, such as an electrical cable, a hose reel, a washing gun and corresponding spray lances.
  • the cable connected to the switch box is either folded and held by hand during transport or fastened by means of a clip or the like.
  • the remaining parts generally have no connection to the pump unit, so that they are often forgotten or lost.
  • Mobile pump units with an essentially cubic housing are known, which for example releases a control panel and a filler neck for fuel for heating.
  • An attachment is provided on an upper edge of the housing with a round recess into which a spray lance can be placed, which is attached to a washing gun.
  • the rear end of the handle of the washing gun is clamped in a rubber part that is attached to a bracket for moving the pump unit.
  • DE-A1-34 00 568 shows another mobile pump unit with a cubic housing, in one side wall of which there is an opening is attached, from which a tube extends obliquely inwards.
  • the opening and the tube are dimensioned such that a washing gun with a short spray lance can be used.
  • the K ⁇ RCHER catalog '82, print number 0182.165000cb1 / 600 from Alfred Kärcher GmbH & Co., 7057 Winnenden shows on page 9 a portable pump unit with a cubic housing and a separate handle, which is approximately in a vertical column the center of the pump unit extends in the horizontal direction.
  • the handle is rounded on the underside and has a cylindrical recess on the top for inserting the spray lance of a washing gun.
  • the cubic housing is space-consuming; the handle must be attached to its own column and the housing must be of such a shape that it can be placed around the column.
  • the invention has for its object to provide a pump unit with a housing with reduced space requirements, which makes the pump unit easy to carry with the simplest construction and simplest manufacture and also offers options for attaching the elements required in operation.
  • the two half-shells of the housing have a simple shape and are easy to manufacture; they are ideally adapted to the contours of the pump unit, the horizontally extending handle being integrated on the housing halves.
  • the figures show a pump unit 10 with a housing 12 designed according to the invention, which preferably consists of plastic.
  • the housing 12 is composed of two half-shells 14 and 16 and a front end part 20 which are held together along their contact edges 18 and 22 by means of clamping devices attached or formed inside the half-shells or the end part, so that a stable housing is obtained .
  • the housing 12 encloses a motor 24 with a pump 26 flanged thereon, a switch box 30 for the motor 24, a capacitor 28 and fittings generally designated 32.
  • the housing 12 provides a view of a manometer 34, access to the lid of a lubricant container 36, a handle 38 for a control valve, an outlet connection 40 and an inlet connection 42.
  • a detergent supply 78 can also be connected to the outlet connection 40.
  • the housing 12 is now designed such that the accessories required in connection with the operation of the pump unit can be attached to the housing 12.
  • an extension 46 is pulled upwards in the area above the electric motor 24, to which a handle 48 extends essentially parallel to the longitudinal axis of the pump unit.
  • the handle 48 is adapted to the underside of the human hand and executed approximately with a semicircular jacket.
  • On the upper side of the handle 48 there is a recess 50 running in the longitudinal direction with an approximately likewise semicircular cross section into which an outlet pipe 52 of a washing gun 53 fits.
  • the back 55 (Fig. 2) also has a recess (not shown) for receiving the protective bracket of the washing gun 53.
  • the design and dimensions of the recesses are chosen so that there is a certain clamping effect between the washing gun 53 or its tube 52 in the Deepens.
  • An upwardly open, semicircular drum 60 with an inwardly drawn outer edge 61 for receiving a hose reel 62 is formed on the rear end face of the two half-shells 14 and 16.
  • the projection 46 encloses the necessary large capacitor 28, which is difficult to attach to the outer periphery of the motor 24 when the housing is absent and is damaged when the housing is absent.
  • the front half-shell 16 is provided in the area of the switch box 30 with a side extension 64 which has, for example, one or two depressions 54.
  • the front end piece 20 has a lateral extension 58 with, for example, two mutually parallel depressions 56.
  • the depressions have such a width that conventional spray lances 66 can be clamped into the depressions 54 and 56.
  • an electrical connection cable 68 is led out, which can be placed in loops in a recess 72 which is transverse to the longitudinal axis the pump unit runs between the switch box 30 and the lubricant reservoir 36.
  • a recess 72 which is transverse to the longitudinal axis the pump unit runs between the switch box 30 and the lubricant reservoir 36.
  • the two housing half-shells 14 and 16 have a stable base 82 which rests on feet 80, so that the pump unit 10 is in a stable position.
  • the stability is further increased in that a motor base 84 is rigidly connected to the floor 82 by means of fastening devices, for example screws 86.
  • holding means for example springs 88, can be provided at a distance from one another, into which a tool, not shown, such as a wrench, can be clamped.
  • the pump unit 10 described above is gripped in the form shown in FIG. 1 on the handle 48 and carried to the place of use. It should be noted that the handle 48 is positioned longitudinally so that there is approximately equilibrium.
  • the washing gun 53 is removed from the handle 48 and the hose reel 62 is screwed onto the outlet 40.
  • the other end of the hose reel 62 is either already connected to the washing gun 53 or is attached to it.
  • the desired spray lance 66 is attached to the outlet pipe 52 of the washing gun 53 and finally the plug of the electrical cable 68 is inserted into a socket.
  • the input 42 is connected to a hose, not shown, of the water delivery source.
  • the motor is excited and there by means of a key switch arranged on a small control field next to the valve 38 with the pump unit 10 started up.
  • the hose is rolled up to form the hose reel 62 and the drum 60 is placed.
  • the spray lance 66 is removed from the washing gun 53 and clamped into the depressions 54, 56.
  • the electrical plug is pulled out and the cable 68 is placed in loops in the recess 72. After inserting the washing gun 53 into the handle 48, the pump unit 10 is ready for transport again.
  • the housing 12 consists of two half-shells 14 and 16 and a front end piece 20.
  • the front end piece it is possible to design the front end piece as part of the half shells.
  • the solution illustrated has the advantage that the various protruding elements can be enclosed most easily.
  • the housing according to the invention It is also noteworthy in the case of the housing according to the invention that its shape is closely adapted to the outer contours of the pump unit, which considerably reduces the space requirement compared to cubic housings and greatly improves handling, in particular the load-bearing capacity.
  • the handle is arranged such that it lies above the center of gravity of the pump unit.
