Definitions
- the present invention relates to a mobile floor cleaning device, which is a cleaning tool attacking a floor surface, a cleaning liquid tank and one Dirty liquid container and a suction unit for taking up a cleaning liquid sprayed onto the floor surface and transfer into the dirty liquid container (see EP-A-0 726 057).
- Such floor cleaning devices are in particular as Scrubbing machines used, one as a cleaning tool or more cleaning brushes are used, which on the attack the floor surface to be cleaned and this with the help clean the cleaning liquid.
- the floor cleaning device mount on a mobile chassis that has a metal frame includes, for example, a tubular frame or a frame from plate-shaped metal parts.
- the cleaning liquid tank is usually considered in a housing of the floor cleaning device adjustable, independent container.
- German published application DE-A-30 21 520 is known a cleaning device in which the housing in the area its vertical side walls and in the area of the floor has parallel chamber walls, the closed, chambers communicating with each other as reception space form for the cleaning liquid.
- the known Cleaning device also includes a dirt holding space, in which a dirty liquid container can be set.
- the object of the present invention is a generic Floor cleaning device to be designed so that constructive structure simplified and its weight reduced become.
- the cleaning liquid tank and the dirty liquid container together designed as a one-piece plastic body.
- the latter forms on the one hand the cleaning liquid tank by in the Cavity of the plastic body filled the cleaning liquid can be used to clean the floor area in the area of the cleaning tool is sprayed on the other the plastic body has a double-walled holder which the dirty liquid container is formed.
- This has a double wall and is therefore characterized by particularly good noise insulation.
- Dirty liquid container and cleaning liquid tank can be done in one step through suitable shaping of the one-piece, closed Plastic hollow body are made. An independent Dirty liquid container is not required.
- the hollow body in the rotary sintering or blowing process is made.
- These two are usually used as hollow chamber processes allow designated manufacturing process a particularly robust design of the hollow plastic body.
- hollow chamber processes allow designated manufacturing process a particularly robust design of the hollow plastic body.
- double-walled plastic housing be produced in that individual housing parts each formed by injection molding and then in others Work steps are welded together in the Hollow chamber components in a single Work step made.
- more impact-resistant plastics are used, so that this creates particularly robust components to let.
- the blow molding process uses tubular plastic material inserted through an opening in the hollow chamber tool. Subsequently the plastic tube is inflated with hot air, so that it adheres to the inner walls of the tool adapts and thus the plastic hollow body is created.
- the hollow chamber tool required for the blowing process requires relatively high investment costs that the process has however, the advantage that the hollow body in the shortest possible time can be produced. In comparison, the investment costs for the required tool in the rotary sintering process less.
- the manufacturing process is the rotary sintering process however longer than with the blowing process, it is therefore particularly useful for smaller quantities applied.

- the floor cleaning device can use the cleaning liquid sucked up from the floor surface together with loosened dirt and transferred to the dirty liquid container. This is done in that the dirty liquid container a vacuum is applied by the suction unit, so that a dirty liquid-air mixture over the suction lip is sucked into the dirty liquid container.
- the mouth area of the inlet nozzle overlapped by the separating wall, so that the Dirty liquid-air mixture penetrating into the dirty liquid container first hits the separating wall, where the dirty liquid separates while the air flows around the separating wall and into that Suction unit is transferred.
- the separating wall is arranged on a cover, that covers the dirty liquid container.
- the lid forms thus access to the interior of the dirty liquid container, so that it can be emptied through the lid can.
- the lid forms a holder for the Separating wall.
- the The cover is double-walled and an inner cover and has an outer cover and that the separating wall in the inner cover is molded.
- the dome-shaped, for example designed separating wall is thus in one piece with the inner cover connected, and the shape of the outer cover can change other circumstances can be adapted without being for his training the design of the separating wall comes into play got to.
- the shape of the outer cover is therefore not due to the design the separating wall is bound.
- the lid is formed as a one-piece plastic body is.
- This can advantageously be in one piece Hollow plastic body, i.e. in the rotary sinter or blowing process. So that will on the one hand, the weight of the floor cleaning device according to the invention additionally reduced and on the other hand there is a structurally particularly simple construction.
- the cover comprises a suction channel, with the interior of the dirty liquid container and is in flow connection with the suction unit.
- the lid thus forms part of the flow connection between the Dirty liquid container and the suction unit.
- the suction channel can for example in the one piece as a plastic body trained lid and be molded by suitable Shaping the lid are formed.
- the suction channel runs in the area between the inner and outer cover and via a suction opening arranged on the inner cover with the Interior of the dirty liquid container in flow connection stands.
- the suction channel can thus be carried out in the same step designed as the double-walled lid by the space between the inner cover and the outer cover forms part of the flow connection between the inner lid of the dirty liquid container and the suction unit.
- a Exit channel of the hollow body penetrating outlet nozzle be provided in the area between interior and Outer cover opens. In this way, the interior of the Dirty liquid container through the suction opening, the double-walled Cover and the outlet connection from the suction unit be pressurized with a vacuum.
- Embodiment of the floor cleaning device according to the invention provided that in the area between the inner and outer cover a secondary separator is arranged.
- the secondary separator provides sure that in the area between the inner and outer cover entering droplets of dirty liquid separated and in the dirty liquid container are returned.
- the secondary separator in the area the suction opening is held on the inner cover.
- the secondary separator is in one piece is connected to the inner cover, as this is a special one simple construction allows by the post separator and the lid together as a one-piece plastic body are trained.
- the secondary separator enters the interior of the separating nozzle immersed in the dirty liquid container includes a conical flow tapered entry section that enters the suction opening opens out, and with at least one of the entry section adjacent liquid return opening.
- a conical flow tapered entry section that enters the suction opening opens out, and with at least one of the entry section adjacent liquid return opening.
- the secondary separator particularly preferably comprises a plurality of liquid return openings, that surround the entrance section.
- the floor cleaning device for cleaning a floor surface 12 shown.
- the floor cleaning device comprises a chassis in the form of a one-piece, closed hollow body 14 made of plastic, both in the longitudinal direction of the floor cleaning device - As shown in Figure 2 - as well as across Longitudinal direction of the floor cleaning device - as shown in Figure 1 - Has an essentially H-shaped profile.
- the hollow body 14 comprises in a front part 16 and one Back part 18 as well as in two spaced apart and each connecting the front part 16 with the back part 18
- Side parts 20 - of which in the drawing only a side part is shown - each one essentially vertically extending outer wall 22 and one substantially parallel to it, vertical inner wall 24, the via upper and lower partitions 26 and 28 with each other are connected.
- the front part 16 of the hollow body 14 is essentially a horizontally and centrally between the upper and lower Partitions 26 and 28 extending central part 30 with the Back part 18 connected.
- the middle part 30 also provides one Connection between the two side parts of the hollow body 14. It is formed by an approximately horizontal one Upper edge 32 and a practically parallel to it Bottom wall 34.
- the back of the hollow body 14 extends to the upper end of the floor cleaning device 10 and goes there in one piece via a double-walled control panel 36, on which a steering bracket 38 is held and the one essentially cuboidal recess 40 forms for receiving the Control units 42 of the floor cleaning device 10.
- the entire hollow body 14 constitutes a closed container is formed as a molded part and in the rotational sintering or blowing process is produced.
- the individual walls of the Hollow body 14 are not suitable in the drawing stiffened shape shown, for example by the Formation of reinforcing ribs or by molded-in sikken.
- the hollow body 14 extends over the entire length of the floor cleaning device and across its entire width and forms a stable frame or framework Inclusion of the individual functional parts of the floor cleaning device.
- Such functional parts are, for example, in the area of Side parts 20 of the hollow body 14 on the lower intermediate wall 28 rotatably held wheels 44, 46 and one below of the hollow body 14 arranged and engaging on the bottom surface 12 Disc brush 48, which is about a vertical axis of rotation is held rotatably and by one above the plate brush 48 arranged electric motor 50 is driven.
- the electric motor 50 is just like a suction unit 52 and battery boxes 54 and 56 in a drive room 58 below the Middle part 30 positioned in the circumferential direction of the lower regions of the front part 16 and the back part 18 and the side parts 20 is limited.
- the hollow body 14 forms an im essentially cuboid receptacle or recess in shape a dirty water tank 60.
- the interior of the dirty water tank 60 is about one in the area of the control panel 36 lid held pivotable about a horizontal axis 62 accessible on the upper partitions 26 the interior of the dirty water tank 60 rests sealingly.
- the cover 62 is double-walled. It has an inner cover 65 and an outer cover 67 on.
- a continuous inlet channel 64 is formed in the hollow body 14, which is penetrated by an inlet connection 66.
- the latter stands over a suction hose 68 with an in Driving direction of the floor cleaning device 10 behind the plate brush 48 on the bottom surface 12 engaging suction lip 70 in Flow connection and opens into the interior of the dirty water tank 60.
- an inlet connection 66 stands over a suction hose 68 with an in Driving direction of the floor cleaning device 10 behind the plate brush 48 on the bottom surface 12 engaging suction lip 70 in Flow connection and opens into the interior of the dirty water tank 60.
- Figures 3 and 4 becomes the mouth area facing away from the suction hose 68 72 of the inlet connection 66 by a dome-shaped one Separation wall 74 overlapped in the inner cover 65 is molded.
- a continuous outlet channel in the hollow body 14 76 molded from an outlet port 78 is penetrated. This creates a flow connection between the suction unit 52 and a suction channel 80, the limited by the inner cover 64 and the outer cover 66 becomes.
- the suction channel 80 is connected to the suction opening 82 Interior of the dirty water tank 60 in flow communication.
- the dirty water tank 60 can thus through the suction opening 82, the suction duct 80 and the outlet connection 78 are subjected to a vacuum from the suction unit 52, so that received by the suction surface 70 from the bottom surface 12 Dirty liquid together with sucked in air the suction hose 68 and the inlet connector 66 in the Dirty water tank 60 is sucked in.
- Flows through here a dirty water-air mixture the inlet connection 66, and the sucked-in dirty water bounces due to its inertia against the separating wall 74 and then drips into the Dirty water tank 60.
- the sucked-in air flows around the Separation wall 74 and is via the suction opening 82 in the Suction channel 80 and the outlet port 78 sucked.
- the Mouth area 72 thus forms in combination with this in the distance surrounding separating wall 74 a separator that the dirty water-air mixture in its two components separates so that the dirty water in the Dirty water tank 60 remains while the air is sucked out becomes. It is to be avoided in this way that Dirty water in the area of the suction channel 80 and from this reaches the suction unit 52 via the outlet connection 78, so that the function of the suction unit 52 is guaranteed remains.
- the conical entry section 88 opens into the suction opening 82 and has for the in the suction channel 80 inflowing air due to the direction of flow continuously reducing flow cross-section Increase in flow velocity. After passing the suction opening 82 experiences the air flowing through an abrupt decrease in their flow rate because The flow cross-section now suddenly expanded. This in turn may have a separating effect on them entrained dirty water droplets, i.e. the Post-separator 84 has an overall cyclone-like mode of operation. 86 separated in the area of the separating nozzle Dirty water droplets can then pass through the liquid return openings 90, the suction opening 82 in the circumferential direction surrounded, back to the interior of the Dirty water tank 60 arrive.
- the cover 62 of the floor cleaning device 10 thus does not have only the function, a flow connection between the suction nozzle 78 and the interior of the dirty water tank 60, but the cover 62 also has the Post separator 84 and forms the separating wall 74, which in Combination with the mouth area 72 of the inlet nozzle 66 forms a main separator.
- the lid also provides 62 a double-walled closure of the dirty water tank 60 is represented by the cover 62 and the one-piece, closed hollow body 14 completely double-walled is completed. This double-walled design of the Dirty water tank 60 also has strong insulation Flow noise result. Since also the electric motor 50 and the suction unit 52 in the circumferential direction of double walls are the operation of the floor cleaning device 10 very quiet and therefore very user-friendly.
- the hollow body produced using the rotary sintering or blowing process 14 serves on the one hand as a supporting frame or chassis the floor cleaning device 10, on the other hand forms the hollow body 14 a cleaning liquid tank.
- the floor cleaning device 10 forms the hollow body 14 a cleaning liquid tank.
- openings not shown can cleaning liquid from the hollow body 14 at the level of the plate brush 48 to cleaning floor surface 12 are sprayed. Under the effect the plate brush 48, the bottom surface 12 is then cleaned and the sprayed cleaning liquid becomes together with dirt particles by means of the suction lip 70 from the bottom surface 12 resumed and in the dirty water tank 60 transferred.
- a float valve 92 is arranged. This comprises a valve body in the form of a float 94, which is held vertically displaceably in a valve housing 96 is that is placed on the separating nozzle 86.
- the electric motor 50 of the floor cleaning device 10 can in the battery boxes 54 and 56 arranged batteries operated become.
- dash-dotted in Figure 2 shown configuration is provided Electric motor 50 does not have a direct in the drawing Connect the illustrated power cord to an electrical outlet. In In this case, additional batteries and thus also the battery boxes 54 and 56 are omitted.
- the thereby gained There is space for an expansion of the waste water tank 60 and an increase in the volume of the hollow body 14 and so that the detergent tank can also be used.
- the area of the rear part 18 adjacent to the back can be used for this purpose
- Middle part 30 - as shown in broken lines in FIG. 2 - down to the level of the axis of rotation of the impellers 44 and 46 to be pulled.
- the mains powered version differs thus from the battery version of the floor cleaning device 10 in essentially only by the shape of the hollow body 14. Da this is produced in a rotary sintering or blowing process is, the shape of a simple insert in the hollow chamber tool to be changed. It is therefore not complex Tool changes required to take place instead of a battery version a mains powered version of the floor cleaner 10 manufacture.
