Definitions
- the invention relates to a cleaning head for a cleaning device for window and facade surfaces, the cleaning head preferably having a generally trough-shaped cleaning chamber which is open at the end and is surrounded by an annular, circumferential suction channel.
- the cleaning head can, for example, be an ultrasonic cleaning head which is provided with a resonator plate which forms the bottom of the cleaning chamber.
- the resonator plate is connected to a piezo oscillator, which causes the ultrasonic vibrations that are transmitted from the resonator plate to the wash water in the cleaning chamber, which fills the cleaning chamber when the cleaning head is in operation.
- the cavitation caused by the ultrasonic energy quickly and effectively removes the dirt particles on the surface to be cleaned.
- the cleaning liquid fed into the cleaning chamber with overpressure causes a gap between the front edge edges of the peripheral wall of the cleaning chamber and the surface to be cleaned during operation, the cleaning liquid -2-
- the suction channel surrounding the cleaning chamber which can be formed, for example, as a cross-sectionally rectangular groove in the edge of the peripheral wall and is connected to a vacuum source via a discharge channel.
- the cleaning liquid / dirt mixture is sucked into the suction channel together with air.
- the invention preferably relates to a cleaning head, in the cleaning chamber of which cleaning agents such as e.g. Brushes are arranged that rotate during the cleaning process.
- the cleaning liquid can be sprayed out of the brush holders against the surface to be cleaned.
- a suction channel which preferably surrounds the cleaning chamber in a ring, can be surrounded by a further ring-shaped channel into which air is introduced from a compressed air source and is sucked into the suction channel from the outside.
- the cleaning head works with other means, for example with water vapor, which can be provided with suitable additives and is directed onto the surface to be cleaned.
- the present invention is therefore based on a further aspect of the task of designing a cleaning head so that all of the liquid that is still in the region of the cleaning head at the end of a cleaning process can be automatically removed from the disc, etc.
- the cleaning head according to the invention is provided with a plurality of depositing devices which have contact elements which can be advanced beyond the end plane of the cleaning head, in order in this way to produce a gap of a predetermined size between the front edge edges of the cleaning head and the surface to be cleaned.
- Tappets, pins or the like are preferably provided as contact elements, which are between a retracted initial position and the advanced position -4-
- the plungers or the like of the settling device are advantageously pretensioned by a spring device into the retracted starting position, in which they are flush with the end plane of the cleaning head or are a little withdrawn.
- the plungers or the like are extended or advanced in order to produce or maintain the desired gap between the cleaning head and the surface to be cleaned . Wash water from the cleaning device can be used to advance the plungers.
- the cleaning head has, for example, two opposing pairs of plungers in the region of the short edges of the mostly rectangular cleaning chamber, these pairs can each be fastened to a common bolt which is arranged displaceably in the rear region of the cleaning head.
- An expandable container can be provided behind this bolt, for example an expandable hose closed at the ends or the like made of a rubber-like material which can be connected to a water source and, when water is supplied, pushes the bolt as far as it will go, thereby reducing the plunger by one advance the predetermined distance of about 0.2 to 0.5 mm, preferably about 0.3 mm, over the end plane of the cleaning head.
- the cleaning head can be provided with a plurality of hydrostatic bearing devices, which is particularly preferred if it is a cleaning head with rotating cleaning agents.
- the cleaning head can have, for example, four opposing pairs of hydrostatic position devices, two pairs being able to be located in the corner regions of the cleaning head and two pairs each in the middle region. In between, the two pairs of depositing devices described above can be provided.
- the hydrostatic bearing devices can also be provided according to the invention even with cleaning heads without a tappet.
- the hydrostatic bearing devices each have an end wall that lies in the end plane of the cleaning head, i.e. are arranged flush with the circumferential walls which delimit the cleaning chamber and the circumferential suction duct and also a compressed air supply duct which may also surround the latter.
- a trough-shaped depression is preferably formed in the end wall of the bearing devices, which extends elongated in the center within the end wall and into which a channel opens, which can be connected to the cleaning fluid source via a line system. If liquid is supplied to the hydrostatic bearing devices during operation of the cleaning head, then the water emerging from the channel is first distributed in the trough-shaped depression and from there -6-
- a switching element is arranged in the line system of the hydrostatic bearing devices, which not only prevents the supply of water, but can also connect the hydrostatic bearing devices to the vacuum source or vacuum source of the cleaning device.
- the result of this is that the liquid remaining on the surface to be cleaned is not only sucked off through the circumferential, annular suction channel, but also through the hydrostatic bearing devices. This further increases the effectiveness of the final drying process.
- 1 is an end view of a brush cleaning head
- Fig. 3 shows a section through the brush cleaning head along the line III-III in Fig. 1 and
- FIG. 1 shows an end view of a cleaning head 1 which contains a cleaning chamber 2 which is surrounded by an annular suction channel 3.
- 5 brushes 4 are arranged in the cleaning chamber 2 and rotate during the cleaning process. Cleaning liquid emerges from openings, which is distributed in a circle as a result of the rotation of the brushes (reference number 5) and is thus sprayed against the pane to be cleaned.
- the bristles 6 of the rotating brushes 4 rest on the surface to be cleaned and carry out an effective cleaning process.
- the suction channel 3 is formed by two walls 8, 9, which are arranged at a short distance from one another on the base body of the cleaning head 1, designated as a whole by the reference number 7, which preferably consist of sheet metal.
- the suction channel 3 opens into the rear area of the cleaning head 1 into a circumferential ring channel 10, which is connected via through bores 11 of a transverse wall 13 to a collecting space 14, from which the extracted liquid / dirt / air mixture is sucked off through a line 15, which is connected to a vacuum source.
- the cleaning head contains 8 hydrostatic bearing devices 16, which are located opposite each other in pairs and in the end face 17 of which faces the surface to be cleaned, an elongated trough-shaped depression is formed, into which a channel 19 opens, through which water can be fed, which is below the end face 17 forms a thin layer of water as the hydrostatic bearing of the cleaning head during the cleaning process. Air can also be sucked in through the channel 19 towards the end of a cleaning process by connection to the vacuum source of the cleaning device, which draws off residual liquid from the surrounding area. -8th-
- the cleaning head 1 also contains four settling devices 20, two of which are also opposite each other in pairs.
- the settling devices 20 each have a plunger 21 which, after or shortly before the water supply to the hydrostatic bearings is shut off, can be advanced beyond the end plane 22 (FIG. 2) of the cleaning head 1 in order to provide a gap of a predetermined width between the cleaning head and the one to be cleaned Adjust or maintain area.
- FIG. 2 shows a section through the edge region of the cleaning chamber 2.
- the channels 19 of the hydrostatic bearing devices 16, which run perpendicular to the end plane 22, are connected at their upper end in FIG. 2 to a hose system 24, through which water can be supplied to the hydrostatic bearing devices 16.
- the settling devices 20 each contain a pin or plunger 21, the shaft 25 of which has a bore 26 in the wall
- the shaft 25 also passes through the transverse wall 13, a further transverse wall 31 lying behind it, and is anchored in a bolt 32, behind which there is an expandable body 33 which is provided with a water connection 34.
- the expandable container 33 which is made of a rubber-like material, whereby the cross bar 32 moves a small distance, for example a few millimeters, in FIG is moved down until the cross bar 32 hits the fixed wall 31. This defines the advanced position of the head sections 27 of the depositing devices 20.
