Definitions

  • the present invention relates to a floor cleaning machine with a chassis for moving the floor cleaning machine on a surface to be cleaned, with a suction device, which is supported on the chassis and designed for sucking debris from the surface to be cleaned, with a dirt container for receiving the debris, the is mounted on the chassis, with a blower device for generating an air flow in the dirt container, with a suction tube which connects the dirt container with the suction device and in which by the blower means an air flow from the suction device to the dirt container can be formed to dirt from the To promote cleaning surface in the dirt container, and with a dirt container connected to the hand suction hose for sucking dirt from the surface to be cleaned.
  • Such floor cleaning machines are used in particular in the municipal sector for cleaning of external surfaces such as paths or squares, with debris that has been promoted, for example with the help of brooms in the area of the suction device, which may be designed in particular as a so-called suction, with the help of the fan and the device generated air flow is drawn into the dirt container.
  • the blower device is mounted on the dirt container so that an inlet of the blower device to the interior of the dirt container, wherein the inlet and possibly the outlet, which leads into the environment, are covered by a filter, but here only not fine-pored filter screens can be used in order not to limit the volume flow through the blower device too strong. However, these filter screens allow fine dust to pass through, allowing it to enter the environment through the blower device.
  • the flow of contaminated air coming from the suction device and the hand suction hose should be directed into the dirt container so that a large part of the fine dust contained therein is deposited in the dirt container before the air enters the inlet of the blower device To avoid that the environment of the floor cleaning machine is subjected to a high dust load.
  • the dust-laden air should be performed in a suitable manner in the dirt container.
  • suction pipe has a connection in the section between the dirt container and the suction device and that the hand suction hose is connected to the connection.
  • the floor cleaning machine is also equipped in a preferred embodiment with a liquid supply, can be introduced with the liquid in the air flow from the suction to the dirt container, coming from the Handsaugschlauch, possibly dust-laden air is applied to this liquid, so in the of Handsaugschlauch coming airborne dust bound by this liquid and can be better deposited in the dirt container.
  • the liquid supply is thus used both for the air coming from the suction device and for the air coming from the hand suction hose.
  • the liquid used in this case is recovered in the dirt container and returned to the liquid supply. In this way, the liquid consumption during operation is minimized.
  • the hand suction hose is variable in length, for example in concertina shape, designed, and there is provided on the terminal a receiving cylinder which extends vertically upwards away from the chassis.
  • the inner diameter of the receiving cylinder is dimensioned so that the Handsaugschlauch can be accommodated therein, and the Handsaugschlauch extends through the receiving cylinder.
  • the collapsible hand suction hose can be stowed in the receiving cylinder, and it is not necessary to wrap the hose, for example, consuming a corresponding receptacle.
  • the vertical arrangement of the receiving cylinder also allows dirt located on the wall to move under the influence of gravity into the intake manifold and thus also to the dirt container.
  • a sealing plug on the floor cleaning machine is mounted above the receiving cylinder, on which the free end of the Handsaugschlauchs can be pushed sealingly.
  • variable-length Handsaugschlauch is particularly simple.
  • the hand suction hose only has to be pushed onto the sealing plug with its free end when it is still extended. Due to the air flow or the negative pressure in the dirt container and the suction tube, the variable-length hand suction hose is contracted and pulls itself into the receiving cylinder. This simplifies the operation considerably.
  • the receiving cylinder can be bent out elastically from the vertical direction. Then it serves as a kind of strain relief for the hand suction hose.
  • the floor cleaning machine can be configured in such a way that on the chassis in addition to the dirt container spaced to a driver's seat assembly is provided and that the connection between the dirt container and the driver's seat assembly is provided.
  • the receiving device in the form of the receiving cylinder for the hand suction hose is not on the outline of the floor cleaning machine, but on the other hand is easy to reach for an operator. This is especially true when the driver's seat assembly is surrounded by a driver's cab. Then, in particular in the case of an elastically configured receiving cylinder, the hand suction hose can be accessed from both sides of the floor cleaning machine and can be pulled away from the machine by the operator without the need for complicated guides for the hand suction hose.
  • the floor cleaning machine can be configured in an advantageous manner such that the suction device is arranged below the driver's seat arrangement. If then the already mentioned brooms are provided on the side facing away from the dirt container side of the driver's seat assembly on the chassis, the dirt container does not hinder the driver when looking at the brooms, so that such a machine is easy to manage.
  • the embodiment of a floor cleaning machine comprises a chassis 1, are mounted on the wheels 3 and an unillustrated drive for the wheels 3, so that the floor cleaning machine is configured to be moved over a surface to be cleaned 5. While a driven floor cleaning machine is described below, the invention can also be applied to machines which are not self-propelled and / or where the operator runs behind them to guide the machines.
  • the floor cleaning machine is provided with a driver's seat assembly 7, which in this preferred embodiment is surrounded by a car 9, wherein the driver's seat assembly 7, from which the floor cleaning machine can be controlled, is arranged in the front part, while in the rear part a dirt container 11 is mounted for receiving debris on the chassis 1.
  • the floor cleaning machine has a suction device in the form of a suction mouth 13, which is mounted vertically adjustable on the chassis 1.
  • the suction mouth 13 is arranged below the driver's seat arrangement 7 and can be lowered onto the surface 5 to be cleaned.
  • the dirt container 11 is connected via a suction pipe 15 to the suction mouth 13, and on the dirt container 11, a blower 17 is further mounted, the inlet 19 points to the interior of the dirt container 11 and which is configured, an air flow from the suction port 13 to the dirt container 11 through the suction tube 15 through form. In this case, the air sucked through the inlet 17 is then discharged through an outlet 21 to the environment.
  • a liquid line 23 is provided which connects the bottom area of the dirt container 11 with a liquid feed 25 on the suction device or the suction mouth 13. Via the liquid feed 25, water can be conducted into the region of the suction mouth 13 and thus into the air flow from the suction mouth 13 through the suction pipe 15 into the dirt container 11. The water serves to bind dust contained in the air flow, so that it can be easily deposited in the dirt container 11. The water is collected at the bottom of the dirt container 11 in a corresponding sump 27 and returned via the line 23 to the liquid supply 25.
  • the suction tube 15 in the section between the suction device or the suction mouth 13 and the dirt container 11 has a connection 29, via which a Handsaugschlauch 31, the variable-length, d. H. accordion-shaped, is configured, is connected to the suction pipe 15.
  • a receiving cylinder 33 extending vertically in a direction away from the chassis 1 is mounted, the inner diameter of which is sized so that the hand suction hose 31 can be received therein.
  • the hand suction hose 31 extends through the receiving cylinder 33 therethrough.
  • the receiving cylinder 33 is formed of a flexible material so that it can be elastically bent out of the vertical direction in which it normally extends.
  • a sealing plug 35 is attached to the dirt container 11, on which the free end 37 of the Handsaugschlauch 31 can be pushed so that the free end 37 is sealed (see in particular Fig. 3 ).
  • the use of the hand suction hose 31 can be done in the following manner.
  • the blower device 17 For sucking, the blower device 17 generates an air flow, which on the one hand leads from the suction mouth 13 through the suction pipe 15 into the dirt container 11. On the other hand, however, the air flow also leads from the free end 37 of the hand suction hose 31 through this to the port 29 and from there through the suction pipe 15 into the dirt container 11. Thus, the air flowing through the Handsaugschlauch 31, at the end in the same manner in the dirt container 11 as that of the suction mouth 13. Thus The dust is deposited in an optimum manner even in the polluted air coming from the hand suction hose 31.
  • the air coming from the hand suction hose 31 is supplied with liquid, since it also has to flow through the suction pipe 15, through which the air flows from the suction mouth 13, which is supplied with liquid via the liquid feed device 25.
  • the flexibly configured receiving cylinder 33 ensures that the hand suction hose 31 does not buckle in tensile load in the region of the terminal 29 and especially not at the top, the sealing plug 35 facing edge of the receiving cylinder 33, but is bent with a defined radius in this area.
  • connection 29 and the receiving cylinder 33 are disposed between the dirt container 11 and the cabin 9, the free end 37 of the Handsaugschlauch 31 is easily accessible to an operator. He does not have to grab on the top of the dirt container 11 if he wants to start the activity with the hand suction hose 31. As a result, this arrangement is very user-friendly.
