Definitions

  • the invention relates to a device of the type outlined in the preamble of claim 1. Such a device is described in U.S. Patent No. 2,624,899.
  • cleaning is to be carried out by sponge-like inserts trapped by sieve plates in the half-shells of the housing, with which the device comes to rest against the slat to be cleaned, the sponge-like inserts through the feed lines to the half-shells of cleaning liquid is metered and the used cleaning liquid collecting at the edge of the device is discharged through a discharge line.
  • the effect of the cleaning based on the interaction between the sponge-like covering and the lamella is unsatisfactory on the one hand, and on the other hand this type of cleaning is associated with undesirable frictional wear on the lamella.
  • the problem with the previously known device is then still not the proper removal of the used cleaning liquid.
  • the primary object of the invention is to design such a device in such a way that a wear-free but thorough cleaning of the lamella to be cleaned is possible. Furthermore, when cleaning with such a device, it should be ensured that, in particular, used cleaning liquid to be discharged is completely collected.
  • the spray cleaning effected with the new device is more thorough than the surface treatment of the lamellae with a sponge or the like, it is then also gentler on the lamella to be cleaned.
  • the special way of sealing the housing parts in particular in the passage area of the inserted lamella in connection with the targeted suction of used cleaning fluid from the interior of the housing, ensures that when cleaning the lamellae there is no impairment of the environment by splashing or escaping cleaning fluid. This is helped if the liquid supply and liquid discharge from the device are coordinated with one another in such a way that a negative pressure is established in the device.
  • the device can also be operated in the dry process in the manner of a vacuum cleaner. In this case, the device is then connected via the discharge line only to a unit generating a negative pressure in the housing.
  • Embodiments of the device according to the invention result from the subclaims.
  • the body of the device is formed by the two half-shells 11 and 12, which are hinged at 13 by hinges in the direction of arrows A and A 'in FIG. 1 for opening and closing the body.
  • the half-shells 11 and 12 are secured by a lock (14).
  • the corresponding edges of the half-shells 11 and 12 are provided with recesses 111 and 121 on the top, as well as on the underside, which, when the body is closed, form through-slots 11, 16 for the slats of a slat blind to be cleaned.
  • the half-shells 11 and 12 are each equipped with an inwardly oriented spray nozzle 21 and 22 and are provided with two suction mouthpieces, for example 26, 26 '(FIG. 2), each in the area of the passage slots 16 and 17 to which in the Device embedded lamella 31 run out adjacent suction slots, for example 261, 261 '.
  • suction mouthpieces for example 26, 26 '(FIG. 2)
  • suction mouthpieces e.g.
  • seals are provided on the edges of the half-shells 11 and 12 that come into contact with one another when the body 11, 12 is closed, in the illustrated case outside the through-slots 16 and 17 on one of the half-shells, namely the Half-shell 11, a seal 112 which, when the body 11, 12 is closed, abuts against a stop 122 on the other half-shell 12 is coming.
  • the corresponding edge areas of both half-shells 11 and 12 are provided with lip seals projecting against one another (for example 113, 123 in FIG. 2).
  • the body 11, 12 is first unfolded, the opened body 11, 12 is attached to the lamella 31 to be cleaned, and the body 11, 12 is then again surrounded by the passage slots 16, 17 from both sides Body 11, 12 protruding slats 31 closed. Subsequently, the overpressure container connected to the device and containing the cleaning liquid and the underpressure container connected to the device into which the cleaning liquid entered into the device is sucked off are switched on. The device is then displaced over the height of the lamella 31, possibly repeatedly (double arrow B in FIG. 2). After the cleaning process has ended, the units, that is to say the excess pressure container and also the negative pressure container, are switched off or temporarily discarded and the device is opened for conversion to the next lamella to be cleaned (arrows A in FIG. 1).
