DE2907911A1 - Upholstery vacuum cleaner with rotary brush - incorporates spray nozzles for cleaning liq., and is mounted on drive shaft coupled to flexible shaft - Google Patents

Abstract

The upholstery cleaner incorporates a rotary brush (19) with spray nozzle (7) for cleaning liquid application. The drive shaft (23) for the brush is mounted in a housing (29) with a connection (30) to a flexible chart of the vacuum cleaner. The housing (29) has a longitudinal duct (28) with a lateral connection (27) for the cleaning liquid inlet. A pipe extends the duct to deliver the cleaning liquid to the spraynozzles. The brush may be disc-shaped and may be secured on the shaft by a nut (22). A stationary protection shield (11) may be coupled to the housing. A suction nozzle (18) may be arranged similarly.

Description

t'Extractor with immediate mechanical processing and immediate

Extraction for upholstered furniture or the like. "The invention relates to an extraction device with immediate mechanical processing and immediate suction for upholstered furniture or the like. Brush driven by an XSYShil rotary drive, immediate suction by means of a water suction device and supply of a cleaning liquid from a pressure vessel to the spray nozzles.

The invention is based on the object as simple as possible Device with perfect cleaning of the surface to be cleaned.

The invention accordingly consists in the fact that the following features each fdr or in connection with each other are provided a) The rotatably mounted in the housing and the brush shaft serving as a drive shaft has a clamping spigot for connection to a flexible shaft, which at the end (other) is connected to a drive motor and is driven.

b) The longitudinal channel installed in the housing through which the supply of the Cleaning fluid takes place, is connected to a pipe at the exit to which then different nozzles are attached.

A side connection with a is provided for the supply adjustable valve.

c) The pipe connected to the housing at the end of the longitudinal channel on the inside diameter, inside the splash guard that is attached to the housing, along the side wall to the starting point of the pipe.

The end of the tube is closed so that the cleaning liquid only on the various attached nozzles with the appropriate pressure on them cleaning surface is injected directly.

d) The drive shaft mounted in the housing with which the brush is driven is used for direct mechanical processing on the object to be cleaned, used during the extraction process.

e) The splash guard connected to the housing, preferably made of plastic, with downward-facing brush elements on your circumference, shields through the rotation the brush thrown outward # liquid and carving particles outside objects or people placed on the brush.

f) The cladding (suction nozzle) attached to the splash guard with connected to the housing, is used for immediate suction after the extraction process. Which from the suction nozzle through the inclined channel in the housing to the shaft of the housing he follows.

Then further suction takes place through a suction hose of the from the shaft of the housing is connected to a water suction device.

As a result of the connectability according to the invention to the rotary drive Any common commercial drilling machine can be used for the drive.

Because the cleaning liquid is supplied through the spray nozzles of the pipe and, in particular, under pressure, can also be in particular perfectly a cleaning mixture for gentle cleaning bzeX Extract with simultaneous mechanical processing and immediate suction To the axial securing of the 8ü-rstschafts 1-2 in the housing @@, are two ring-shaped Grooves 5 attached, which serve to provide a fit for the pressed-in ball bearings to ensure, then pressed into the brush shaft 12 and with 2 Seager rings 16 and 17 is secured.

The brush shaft 12, which is made of any material such as steel or can also consist of light metal, has an extension 23 on which the Brush 19 is secured by means of a nut 22.

At its upper end, the brush shaft runs into a clamping spigot 30, onto which a thread (optional) from rnlo is untwisted so that the The flexible shaft provided for this can be screwed in with an m10 internal thread.

The brush is expedient per se in a known manner as a plate brush 19 and secured on the shaft 23 by means of a nut 22. The brush 19 is provided with downwardly directed brush elements 9 on your circumference, e.g. made of Wooden or plastic disc.

The splash guard 11, preferably made of Hols or plastic, has the Task of spraying off cleaning fluid or dirt ponds from the side by the rotating brush 19 to prevent.

The splash guard, which is provided with a downward-facing brush belly element 24 11S are attached to the turned attachment 1 with the housing 29 provided for this purpose associated therefor approach 8.

A sleeve-shaped handle with a connection set is used for feeding 27, to which a liquid supply means can be connected, e.g. a hose, which is slipped over the handle and becomes a die-cleaning liquid contained Storage container or the like. Leads.

There is preferably an adjustable valve on the handle around the cleaning fluid that comes from the pressure vessel or a pressure pump regulate.

The further supply of the liquid from the starting point 27 then is pressed into the longitudinal channel 28, from the longitudinal channel 28 which is connected to the pipe 6 is the continuation of the liquid from pipe 6 to the bent pipe 5 to to the end that is bent on the inside diameter of the splash guard 2 further. The exit the cleaning liquid then takes place via the spray nozzles 7 fitted with a Spray diameter of optionally lamb.

The cladding attached to the splash guard 18 -Sa% 4düse- with the housing 29 is connected, is used for the immediate suction after the extraction process.

The suction takes place through the suction nozzle 18, optionally made of steel or Light metal that has a width of Iomm (optionally.

Further suction takes place through the inclined canal 3, in the housing 29, optionally between 8 -15 p to the shaft 31 in the housing 29, about the shaft 31 mounted in the housing 29, is provided so that any conventional Suction hose 4, into which the attached shaft 3t can be inserted, takes place now the further suction to a water suction device intended for this purpose.

Mode of operation After pressing the switch, the drive chine the brush is set in rotation. At the same time the cleaning fluid is over the hose line is pressed into the interior of the housing to the starting point of the pipe.

You can now guide the extraction device with light movements without pressure | circling over the fabric to be cleaned.

The liquid escaping from the pipe via the attached spray nozzles, he follows now with pressure on the object to be cleaned.

With the light circular movements with the extractor, it takes over Now the brush does the further mechanical work and massages the cleaning liquid into the tissue in the object to be cleaned to ensure 100% extraction.

The splash guard attached above the brush -proof with the housing connected now prevents that in the mechanical work by the brush rotation none Particles of dirt fly outwards.

After the immediate mechanical processing, the suction nozzle is now used the accumulated dirt particles - cleaning mixture with connected and detached Dirt sucked up through the housing to the Illassersauqer provided for this purpose.

After completing this process, the cleaned object is now in the base tissue and in the surface with a 1DO '# security "dirt-free".

Due to the moisture of the cleaning fluid that gets into the object is massaged in, the drying time now takes approx. 1-3 hours.

After the drying time, the cleaned object can be used again be taken.
