By this design scheme of lid 56, transverse pipe 28 and tube frame section 20 and 21 are in recess portion 24 and 26 and horizontalIn the region of the front section of pipe 23 (and unshowned horizontal tube), relative to it is vertical have with the edge 70 of lid 56 it is relatively large away fromFrom.The vertical area that at least along the longitudinal direction 19 by pump assembly 45 is occupied of the pump assembly 45 relative to high-pressure cleaning device 10 as a result,It is arranged in domain between edge 70, transverse pipe 28, tube frame section 20 and 21 (except the upper end of regulating element 53).With the partyFormula is situated between at least in by the pump assembly 45 along the longitudinal direction region of 19 coverings before being formd between transverse pipe 28 and edge 70Enter opening 71, and forms lateral intervention opening 72 or 73 between tube frame section 20 and 21 and edge.Based on recess portion24 and 26, it is king-sized into opening 72 and 73.
As a result, when lid 56 occupies closed position, user oneself can operate pump assembly 45 and its component, thisWork and time intensive use high-pressure cleaning device 10 in the case of be particularly advantageous.For example, high-pressure hose 51 can be with heightIt crimps mouth 50 to connect, and can be dismantled from the high voltage interface, without raising lid 56.In addition, the pressure of the fluid transportedPower can be adjusted by regulating element 53, and without opening lid 56.For this purpose, user is open by the intervention on left side 1672 come to operate be enough.In addition, oil level by front side 15 intervention opening 71 Visible human plan be it is possible, this be becauseIt is covered also without by lid 56 by window 54.In addition, user can be by intervening 72 identification of opening and determining fluid filterWhether 47 must be replaced or cleaned.If it is desirable, so user may pass through intervention opening 72 to capture fluid mistakeFilter 47, and manually and toollessly dismantled the fluid filter from pump assembly 45 by oneself.In the corresponding way,In the case where not opening lid 56, the fluid filter 47 being replaced or cleaned manually and toollessly can be connected to pump machine againIn group 45.
The possibility of control, adjusting and the maintenance work mentioned before pump assembly 45 is carried out in the case where not opening lid 56Property improves the navigability of high-pressure cleaning device 10, and reduces its downtime, this is conducive to work and time intensiveUse.
19 behind pump assembly 45 along the longitudinal direction, and lid 56 has side wall section 74 and 75, from edge 70s courtThe direction of placed side 18 extends downwardly.Side wall section 74 and the 75 big form designs for showing the triangle beyond cap portion, so as toIt is enough that motor pump unit 43 is laterally covered behind pump assembly 45.
Extraly, motor pump unit 43 is covered by two fastening elements in a lateral direction, these fastening elements are currentIt is designed as plate shape, and one of fastening element 76 is only shown in the accompanying drawings.Fastening element 76 makes horizontal tube 23 and VERTICAL TUBE22 are connected with each other, and the support component at the side wall section 74 of lid is formed simultaneously for the closed position that lid 56 occupies.The fastening element 76 of corresponding plate shape is arranged in right side 17, and VERTICAL TUBE 25 is made to be connect with unshowned horizontal tube, and shouldFastening element is simultaneously as the support component for side wall section 75.
As it has been mentioned that as, lid 56 can occupy open position.In order to be transferred to open position, lid can be around axis of oscillation57 swing backwards, and it is transferred to roughly vertical position (Fig. 2 and Fig. 4).In open position, motor pump unit 43 exposesCome, and pump assembly 45 can be operated in a particularly simple way for the user.User can be from front, a left sideSide, the right and maintenance work is operated and executed herein to pump assembly 45 above, and is for example disassembled it from motor 44.In addition, being proved herein advantageously, transverse pipe 28 is in the perpendicular lower section for being upwardly arranged at pump assembly 45.However, transverse pipe 28 with putThe distance for setting face 18 is advantageous, more easily to overcome the out-of-flatness on ground when high-pressure cleaning device 10 moves, and it is sameWhen downside protect pump assembly 45.
In closed position, lid 56 can be locked, and can be especially locked up.For the purpose, tube frame 12 and lid 56On locking member and especially locking element can mating reaction.In order to lock lid 56, bolt head 40 is used as the first locking member,It can be with the second locking member mating reaction of 77 form of rib being laterally formed on lid 56.If 56 swing backward of lid,So rib 77 slides in and out on bolt head 40, this is because lid 56 can generally deform in the region of rear side 14.It is beatingUnder open state, bolt head 40 and rib 77 are mutually locked, wherein the front support of rib 77 is swung on bolt head 40 to overcomeTo closed position fixed cover 56.In left side, using bolt 39 come locking lid 56 in VERTICAL TUBE 22, and on right side, perpendicularLocking is carried out on straight tube 25.
The locking of lid 56 can intentionally be cancelled first by user using bolt 39, and lid 56 is thus made to be transferred to closingPosition.
This design scheme simplifies height (wherein, for the fixed retaining element for grasping bow 36 simultaneously for locking lid 56)Press the design in the structure of cleaner 10.
