Definitions
- the invention relates to a wet cleaning device according to the preamble of claims 1 and 18 respectively.
- the cooling air flow hits and the suction air flow in the swirling space at an angle to one another. This slows down the two air flows very much, so that they only get out of the wet cleaning device at low speed get out. Due to the collision of the Both air flows also have a resonance effect, which leads to a leads to significant noise reduction. This works the invention Wet cleaning device with little noise. In addition, the turbulence and the achieved with it strong speed reduction achieves that dust particles not whirled up the surface of the surface to be cleaned become.
- the wet cleaning device shown in Figures 1 and 2 is a so-called wet vacuum, which is used for example for cleaning floors. It has a liquid container 1 serving as the lower part of the housing. It can sit on a base with wheels or castors. It is also possible to equip the liquid container 1 itself with wheels or rollers. On the liquid container 1 there is an upwardly projecting upper housing part 2, 3, 29, 23 in which a motor 4 with a motor housing 5 and a turbine (blower) 6 are accommodated.
- the upper housing part 2, 3, 29, 23 consists of a connection part 3 sitting on the liquid container 1, a middle part 29 lying thereon and a closing part 23 sitting on it, which are covered by a cover part 2.
- the motor housing 5 has peripheral openings 5 for an engine cooling air flow P. Beneath the engine is the turbine 6, which is driven by the engine 4 and also has peripheral outlet openings 7.
- the liquid container 1 has an intake 9, to which a Suction hose can be connected.
- the intake manifold 9 protrudes downward within the liquid container 1, advantageously so far that the outlet opening of the intake 9 below the Liquid level.
- the suctioned through the intake port 9 polluted air is inevitably mixed with the liquid F, which is preferably water.
- the lid 10 has a central opening 11 through which a separator 8 projects into the liquid container 1.
- the separator 8 lies with a retaining ring 8 on the edge of the opening 11 and is attached to the underside of the housing middle part 29 via an annular carrier 20.
- the connecting part 3 has an outer wall section 3 on the side opposite the intake manifold 9 with an outer wall 2 of the cover part 2 is approximately aligned.
- the wall 3 has an opening 12 in which a distributor cap 13 is seated (FIG. 1). Within the connection part 3, the distributor cap 13 projects through an opening 14 an axially extending wall 14 which is provided between radially extending walls 15 and 16.
- the wall 14 is opposite a wall 17 which slopes slightly conically inwards and has an upper flange 18 which projects radially outwards. It has a plurality of through-openings 19 for the suction air flow P which are located next to and behind one another with radial and circumferential spacing on.
- the wall 17 merges into the radial wall 16, with which the housing connection part 3 is fastened on the carrier 20 which carries the turbine 6.
- the separator 8 is partially overlapped by the carrier 20. It lies on a slightly convexly upwardly curved bottom 21 'of an inner housing part 21. To the floor 21 closes an upwardly projecting wall 22 on which the flange 18 of the connecting part 3 rests.
- the cover part 2 is pot-shaped and surrounds the motor housing 5 and the end part 23, which in turn surrounds the motor housing 5 at a distance.
- the cover part 2 extends to the intake port 9 and on the opposite side to approximately the height of the turbine 6.
- an outlet opening 24 is formed between the free edge of the housing wall 2 and the housing wall 3 .
- the end part 23 has an opening 26 on its upper floor 25, which extends perpendicular to the axis of the motor 4. Below it is a fan wheel 27, which is accommodated in the motor housing.
- the middle part 29 has an upper, radially extending wall 30 with an inner circumferential web 31, with which the middle part 29 bears against the turbine 6.
- the wall 30 merges into a downwardly projecting jacket 32, the free edge 30 of which rests on the flange 18 of the connecting part 3.
- the free edge 30 has in the area of the outlet opening 24 from the wall 15 of the connecting part 3 a small distance, whereby a passage opening 33 for the suction air flow P is formed.
- An annular wall 34 protrudes downward from the wall 30 approximately half the width and is approximately the same distance from the jacket 32 and the turbine 6.
- the annular wall 34 lies on the side facing away from the intake port 9 on the wall 15 and in the area of the intake port 9 on the inner edge of the flange 18.
- a front panel 38 is provided which surrounds the intake manifold 9.
- the cooling air flow P flows through the outlet openings 5 outwards into an annular space 40 formed between the motor housing 5 and the end part 23, in which an pressure builds up in the cooling air flow P.
- the cooling air flow P passes through an adjoining the bottom 25 of the cup-shaped attachment part 23 and in the jacket 23 provided passage opening 41 into an intermediate space 39. From here, the cooling air flow P flows down through a between the jacket 32 of the end part 23 and the opposite housing wall 2 flow gap 42 formed into a swirling space 43 adjoining at the bottom.
- the walls 30 and 34, the legs 35, 36 and the turbine jacket 6 delimit a first annular resonance chamber 48. It is connected via the opening 37 to a second resonance chamber 44 located underneath. It is on the side of the wall 17 and the turbine jacket 6 and limited upwards by the wall 15 and the leg part 35.
- the bottom of the resonance chamber 44 is formed by the wall 16.
- the resonance chamber 44 has, for example, a round opening 49 in its wall 17 adjacent to the distributor cap 13.
- the cooling air flow P is from the impeller 27, which rotates on the motor shaft sits, sucked through the front panel 38 of the upper housing part 2.
- the cooling air flow P flows in from the front panel 38 the space 39 in which it is up to the opening 26 in Bottom 25 of the end part 23 flows.
- the cooling air flow P arrives then into the motor housing 5.
- the cooling air flow P flows along it of the engine 4 down, the engine being optimally cooled.
- the cooling air flow P passes the outlet openings 5 'into the annular space 40 between the motor housing 5 and the end part 23.
- the annular space 40 is designed that the cooling air flow P under a building up Pressure flows upwards and out through the passage opening 41 enters the space 39.
- the cooling air flow flows in it P down and enters the swirl space through the flow gap 42 43 a.
- the suction air flow P sucked in a known manner. It flows through the cleaning liquid F in which the dust / dirt particles present in the sucked-in air are retained.
- the intake air P passes to the rotating separator 8, which is provided along its circumference with slots 50 through which the air flows. Any dust / dirt particles still present in the air are retained on or in the separator 8, so that clean air reaches the rotating turbine 6 at the top.
- the air flow P passes through the outlet openings 7 into the resonance chamber 48 which runs in a ring around the vertical turbine axis.
- Its radial outer wall 34 is advantageously made of elastic material, preferably rubber.
- the air flow P is then passed through the annular gap 37 into the second resonance chamber 44 which runs in a ring around the vertical turbine axis. From there the air flow P arrives Via the opening 49 and / or the distributor cap 13 into the third resonance chamber 45, which also rotates in a ring around the turbine axis.
- the air flow P Flow through the passage openings 19 in the flange 18 of the connecting part 3 into the fourth resonance chamber 47 which runs in a ring around the vertical motor axis.
- the air flow P passes from it via the passage opening 33 into the swirling space 43.
- the air flow P hits the cooling air flow P there, which greatly reduces the noise of the two air flows and their air and suction noise. As shown in FIG.
- the cooling air flow P and the air flow P meet from above and below each other in the swirling space 43, whereby an optimal sound attenuation is achieved.
- the two air flows P, P meet preferably vertically in the swirling space 43.
- the air flows P, P also meet at different angles in the swirling space 43. Both air flows P and P are deflected so that they get into the environment through the outlet opening 24.
- the flow velocities of the two air flows P, P are mutually canceled by the swirling in the swirling space 43 or reduced so much that no dust can be whirled up from the floor when exiting into the environment.
- the distributor cap 13 is advantageously designed to be flow-optimized. It can also, as indicated by dashed lines in FIG. 1, approximately be conical.
- the distributor cap 13 widens in Flow direction in the direction of the outlet opening 24.
- the lateral surface the distributor cap 13 is for flow optimization in Axial section concavely curved.
- the housing middle part 29, which has the resonance spaces 47 and 48, divides the upper housing part 2, 3, 29, 23 into a lower one Main part with the housing connection part 3 and an upper cap-like Part with the end part 23.
- the outlet opening 24 of the swirling space 43 is advantageously designed such that the exiting air flow is deflected in a certain direction, preferably upwards.
- the edge or edges of the outlet opening 24 are constructed such that they form guide and deflecting surfaces on which the exiting air flow is deflected upward. This prevents dust particles in the surrounding area or on the floor from being unnecessarily whirled up by the escaping air flow.
- the passage opening 33 for the air flow P 1, in the area below the lower edge of the outlet opening 24. This causes the air flow P after its passage through the passage opening 33 inevitably deflected upward so that it can get out through the outlet opening 24.
