The possibility of the control mentioned before carrying out pump assembly 45 when not opening lid 56, adjustment and maintenance work improves the navigability of high-pressure cleaning device 10, and reduces its downtime, and this is conducive to work and the use of time intensive.
19 after pump assembly 45 along the longitudinal direction, and lid 56 has side wall section 74 and 75, its from 70s, edge towards the direction of placed side 18 to downward-extension.Side wall section 74 and 75 shows greatly the leg-of-mutton form design exceeding cap portion, thus laterally can cover motor pump unit 43 below at pump assembly 45.
Extraly, motor pump unit 43 in a lateral direction cover by two fastening elements, these fastening element current design are plate shape, and one of them fastening element 76 is only shown in the accompanying drawings.Fastening element 76 makes horizontal tube 23 and VERTICAL TUBE 22 be interconnected, and for forming the support component at side wall section 74 place of lid the closed position that lid 56 occupies simultaneously.The fastening element 76 of corresponding plate shape is arranged in right side 17, and VERTICAL TUBE 25 is connected with unshowned horizontal tube, and this fastening element is used as the support component for side wall section 75 simultaneously.
As already mentioned, lid 56 can occupy open position.In order to be transferred to open position, lid can swing backward around axis of oscillation 57, and is transferred to roughly vertical position (Fig. 2 and Fig. 4).In open position, motor pump unit 43 comes out, and can operate pump assembly 45 in a particularly simple way for the user.User can from above, the left side, the right and above pump assembly 45 operated and perform maintenance work at this, and such as it to be disassembled from motor 44.In addition, prove advantageously at this, transverse pipe 28 is arranged in the below of pump assembly 45 on vertically.But transverse pipe 28 is favourable with the distance of placed side 18, to overcome the out-of-flatness on ground more like a cork when high-pressure cleaning device 10 moves, and simultaneously at downside protection pump assembly 45.
In closed position, lid 56 can be locked, and especially can by locking.For this object, tube frame 12 is with the locking member on lid 56 and especially locking element can mating reaction.In order to locking cover 56, bolt head 40 is used as the first locking member, its can with the second locking member mating reaction of rib 77 form be laterally formed on lid 56.As operculum 56 swings backward, so rib 77 outwards slides on bolt head 40, this is because lid 56 generally can be out of shape in the region of rear side 14.In the on-state, bolt head 40 and rib 77 locking mutually, wherein, the front support of rib 77 on bolt head 40, thus overcomes with being rocked to closed position fixed cap 56.In left side, VERTICAL TUBE 22 utilizes bolt 39 carry out locking lid 56, and on right side, VERTICAL TUBE 25 carries out locking.
Utilize bolt 39 first can be had a mind to cancel by user to the locking of lid 56, and make lid 56 be transferred to closed position thus.
This design (wherein, for the retaining element of fixing grasping bow 36 simultaneously for locking cover 56) simplifies the structural design of high-pressure cleaning device 10.
