Definitions

  • the invention relates to a cleaning head for a cleaning device for wet cleaning of floor surfaces with a housing, a fixed or pivotally connected to the housing suction nozzle for connecting a suction unit, a device for dispensing a cleaning agent and at least one arranged on a bottom of the housing slit-shaped suction opening for the suction of Detergent from a floor surface.
  • the suction nozzle opens into a suction chamber of the housing, with which the suction opening for sucking the cleaning agent is connected.
  • a cleaning head with the features described above is out DE 100 03 883 C1 known.
  • the known cleaning head has on its underside a mat or fleece-shaped cleaning pad, via which a liquid cleaning agent is applied to a floor surface to be cleaned.
  • suction openings are provided to suck the cleaning agent again from the bottom surface.
  • the cleaning process is referred to as a spray extraction process and is used, inter alia, to obtain a textile floor covering over many years in a new, respectable state.
  • the cleaning head on a textile floor covering is disadvantageous that the detergent is applied only superficially on the floor surface and is not mechanically incorporated into the textile covering. In order to achieve a sufficient cleaning effect, a relatively large amount of detergent must be used. After aspirating the detergent, a high residual moisture remains on the floor.
  • a cleaning head which has a cleaning roller in a roller chamber. Before and behind a bottom-side opening of the roller chamber a sealing lip is provided in each case, which limits an inflow of air.
  • the entering into the bottom opening suction air is passed through a housing of the cleaning head to a back-connected suction.
  • a bypass is provided, which opens with a bottom-side bypass opening behind the bottom opening of the cleaning roller.
  • a cleaning head which has a wet cleaning function.
  • a cleaning roller In a roll chamber, a cleaning roller is arranged, wherein nozzles are provided for the discharge of a cleaning liquid at the front of the cleaning head.
  • the cleaning liquid is sprayed in front of the cleaning head and can then be taken up to a certain extent with the remaining suction air via a bottom-side opening of the roller chamber, wherein in each case a sealing lip is provided in front of and behind the roller chamber.
  • the inclusion of liquid over the comparatively large bottom-side opening of the roller chamber is in need of improvement.
  • electro brushing devices for wet cleaning of floor surfaces which are used both on smooth floors and on textile floor coverings and have an arrangement of oppositely driven brushing rollers.
  • the bottom surface is brushed intensively and applied to the bottom surface cleaning agent supplied to a collecting container. It is not sucked.
  • the detergent must therefore be used in a lower dosage than in a spray extraction process.
  • the residual moisture of the floor covering is therefore lower after use.
  • the invention has for its object to provide a cleaning head for a cleaning device for wet cleaning of floor surfaces, which brushes the wetted with a detergent floor surface and the cleaning agent effectively resumes.
  • the cleaning head should be universal and easy to handle.
  • the object of the invention and solution of this problem is a cleaning head according to claim 1.
  • the suction chamber of the cleaning head comprises a roller chamber, in which at least one rotationally driven cleaning roller is arranged.
  • the roller chamber has on the bottom side a preferably rectangular opening into which a peripheral portion of the cleaning roller dips.
  • the suction opening for sucking off the cleaning agent extends along the base-side opening of the roller chamber and is bounded on its side remote from the opening of the roller chamber longitudinal side of a sealing lip.
  • the cleaning roller provides for the distribution of the cleaning agent and for an intensive mechanical contact with the ground, for example a carpet pile or a smooth floor. Due to the mechanical action of the cleaning roller on the bottom surface, the detergent can be dispensed sparingly. With the suction, however, an increased detergent use for improved cleaning is harmless.
  • dirt particles By entering into the bottom opening of the roller chamber air flow dirt particles can also be recorded and transported. When cleaning textile bottom surfaces flows through the entering into the bottom opening of the roller chamber air flow first the batt and thereby makes a contribution to the drying of the bottom surface.
  • the main amount of the cleaning agent is sucked through the suction opening, which is according to the invention adjacent to the bottom-side opening of the roller chamber and is limited at its side facing away from the opening of the roller chamber longitudinal side of a sealing lip.
  • the sealing lip At the sealing lip liquid collects, which adheres to the floor and can then be effectively sucked as liquid accumulation through the suction opening.
  • the sealing lip is preferably designed as a scraping edge, which is stiff or has only a slight flexibility.
  • flexible wiper lips are advantageous, which create a line on the floor surface and have a Abstreiffunktion.
  • semi-rigid rubber lips are a compromise.
  • the opening of the roller chamber is bounded on the underside of housing surface portions which form the underside projecting Saugmundkanten.
  • the distance of the suction mouth edges from the floor surface to be cleaned has an effect on the suction properties during suction of dirt particles and also influences the drying effect of the air flow entering the bottom opening of the roll chamber. With increasing reduction of the distance between the suction mouth edge and the floor surface to be cleaned, the flow velocity of the airflow flowing around the suction mouth edges increases. With increasing flow velocity, both drops and dirt particles can be absorbed and transported.
  • the housing of the cleaning head preferably has rollers for bottom support. This allows a defined distance between the Saugmundkanten and the floor surface to be cleaned are set up. It is also within the scope of the invention that the rollers or floor sliding elements are height-adjustable and the distance of the suction mouth edges from the floor surface can be changed depending on the nature of the floor surface to be cleaned.
  • the Saugmundkanten can be integrally formed on a lower housing part of the housing or fixed to the lower housing part.
  • the roller chamber consists of a pivotally mounted in the housing insert having angled surface sections with Saugmundkanten.
  • the suction opening for sucking off the cleaning agent preferably adjoins a suction mouth edge.
  • the suction mouth edge rests on the carpet pile, the resulting mechanical movement of the carpet pile reinforcing the suction effect on the adjacent one.
  • the device for dispensing the cleaning agent has at least one nozzle or outlet opening, which may be arranged in relation to a forward movement of the cleaning head in front of the bottom opening of the roller chamber or within the roller chamber.
  • a plurality of outlet openings or nozzles arranged in a row are provided, wherein the Spray jets of the exiting detergent are directed to the surface to be cleaned or the cleaning roller.
  • the suction opening for sucking off the cleaning agent is always arranged behind the bottom-side opening of the roller chamber, based on a forward movement of the cleaning head.
  • suction openings are arranged for sucking the cleaning agent, wherein the suction ports connected to the suction chamber of the housing and at their respective from the opening of the roller chamber applied longitudinal side are limited by a sealing lip.
  • the device for. Dispensing of the cleaning agent has at least one nozzle or outlet opening, which is arranged within the roller chamber.
  • the detergent dispensed within the roller chamber can be sucked off with equal effectiveness both in a forward movement and in a backward movement of the cleaning head, wherein for the suction both contribute an entering through the bottom opening of the roller chamber air flow and the air flows entering through the suction openings arranged parallel thereto.
  • the sealing lips may optionally be connected to a mechanical adjusting device, which raises depending on the direction of movement in each case the front in the direction of movement sealing lip and lower the rear sealing lip.
  • the sealing lips can be alternately stiffened by adjusting movements of stiffening elements or folded away by appropriate adjusting devices.
  • the stiffening elements may for example be designed as a slide, which are each arranged behind a sealing lip and can be moved in and out at the bottom of the housing.
  • the cleaning roller expediently has a trim of spirally arranged rows of bristles.
