Definitions

  • the invention relates to a method and a device for cleaning and / or maintaining floors and / or floor coverings of all kinds by means of a machine, the floor or floor covering to be treated being treated occasionally with an additional medium such as water with the supply of heat, using as a heat carrier a flow of hot air is used that reaches the floor surface through the machine.
  • a carpet cleaning device is known from DE-U-8 304 300.7, which makes use of the electrostatic charge of the dirt particles. Cleaning at elevated temperatures is therefore not intended; however, in EP-B1-0188475 for carpets, cleaning at elevated temperatures between 40 to 80 degrees suggested. Treatment of other soils at elevated temperatures is not intended.
  • a carpet cleaning machine is also described in DE-A-26 15 501.
  • This is a vacuum cleaner compressed air spray and suction system for wet cleaning of permanently installed materials, with which cleaning liquid is pressed onto the material to be cleaned by means of compressed air via a flat jet nozzle and immediately removed again by forced suction.
  • the compressed air can be heated by an electric heater, and the fabric is also dried by forced hot air.
  • a major disadvantage of this system is due to the extremely complex and complicated design, moreover, effective use requires considerable experience. In addition, large amounts of cleaning agents are required and the drying time is relatively long despite heating.
  • the present invention has for its object to provide a method and an apparatus which are suitable for universal cleaning and / or maintenance of floors and / or floor coverings of all kinds such as carpets, plastics, linoleum, parquet, ceramics, stone tiles or marble etc. avoid the aforementioned difficulties, disadvantages and technical limitations of known devices.
  • an essentially constant temperature should be adjustable in the area of the working area without the need to separately heat the supply of water and / or cleaning or care agents.
  • the method and the device are said to be able to achieve such an effective cleaning effect that even thorough cleaning of floors or floor coverings of all kinds with extremely economical use of workers and cleaning or care products while avoiding the use of chemical, in particular ecologically questionable, basic cleaners with less work than is currently feasible.
  • the problem is solved in a method of the type mentioned with the invention in that the machine is a single or multi-disc rotor machine with at least one drive plate, and in that the additional medium and / or a fluid or pasty cleaning or care substrate is gradually heated, wherein it is preheated in a hot air stream in a first stage and then further heated as it passes through the drive plate.
  • the hot air flow or heated additional medium is brought to full effectiveness on the floor surface through the drive plate.
  • One embodiment of the method provides that the additional medium is preheated in the first heating stage using a heatable drip tray.
  • Another embodiment provides that the additional medium is applied through the center of rotation to the surface to be treated. This results in a very good distribution with simultaneous heating of cleaning or care products and floor space.
  • Another embodiment provides that the hot air stream emerges at a comparatively high speed with the formation of an energy-rich flow against the drive plate and the mat, with additional medium such as water or fluid or pasty cleaning or care substrate being heated by the flow pressure and opening up through the drive plate or brush the ground is given up and evenly distributed.
  • a further embodiment of the method provides that the temperature of the machined surface is checked using a temperature sensor which is preferably located in the center of rotation of the rotor.
  • a further embodiment provides that the temperature of the processed surface is set in accordance with a predetermined cleaning or maintenance program and / or according to the type of floor covering. As a result, the use of energy can be set to a comparatively economical level.
  • the device shown in FIG. 1 has a rotor (1) with a drive unit (5) in a motor housing (25).
  • the rotor (1) sits on one (not Shown) in the machine housing (24) and has a drive plate (2), preferably profiled on its underside, with an underlying rotating mat (50).
  • the drive plate (2) is formed with holes (3) or slot-shaped openings (4) and optionally on its underside as a brush.
  • the mat (50) can be designed differently depending on the type of floor covering (49) being processed; for example, when used for carpet cleaning, it has a covering with cleaning bristles.
  • the mat (50) can consist of a porous textile body, for example of a needle fleece, and has on its underside a structural covering adapted to the respective cleaning procedure.
  • mats (50) which are also referred to as "pads". They can consist of fabrics with more or less hard textile material, they can be air-permeable or impermeable for cleaning carpets or fabrics and z.
  • B. consist of polyvinyl fibers. Harder fabrics for basic cleaning are made of polyester or polyethylene (nylon). Brushes with hard bristles are used for roughing or shampooing.
  • pads which consist of disc-shaped nonwovens, for example made of polyester or nylon, can have embedded grinding wheels depending on their hardness. For their identification, such pads are colored differently depending on their lower or greater abrasion. Green colored pads have medium abrasion. They are mostly used in cleaner processes, black pads are used for basic cleaning. Occasionally, pads can also make breakthroughs exhibit.
  • the device has a generator (20) for generating a hot air stream (23), the temperature of which can be adjusted to match the type of floor or floor covering (49) to be worked.
  • a favorable cleaning temperature is, for example, 40 ° Celsius for textile coverings, and a maximum of 80 ° Celsius for non-textile floors and / or coverings.
  • the hot air generator (20) has a blow-out element (21), the mouth (22) of which is arranged just above the drive plate (2).
  • the mouth (22) of the blow-out member (21) is located approximately in the middle between the center of rotation and the periphery of the drive plate (2).
  • the hot air stream (23) and the cleaning or maintenance substrate applied together with it are advantageously applied through the drive plate or the brush (2) and / or the mat (50) onto the floor surface (49) to be cleaned.
  • the industrial hair dryer (20) produces a hot air stream (23) emerging at a comparatively high speed, the action of the hot air, for example through pores in the mat (50) against the floor surface (49), resulting in an advantageous increase in the cleaning action.
  • the advantage is that the amount of heat transported in the hot air stream (23) or from the additional medium is brought into effect through the drive plate (2) and the rotating mat (50) on the floor covering surface (49) being cleaned or cared for .
  • the cleaning and care device according to the invention is equipped with a conventional chassis, for example with two wheels (44), and with a guide rod (45) on the preferably heavy machine housing (24). It has a metering device (38) for cleaning or care products, the outlet opening of which is arranged above the drive plate (2). It can therefore also be used that the metering device (38) has an outlet channel arranged in the axis of rotation (x-x) of the shaft of the rotor (1). It is thereby achieved that cleaning or care agent emerging from the center of rotation is applied uniformly and extremely economically to the surface (49) to be cleaned and distributed there by the rotating mat (50). Furthermore, a temperature sensor extending up to the floor covering (49) to be worked is arranged in the axis of rotation (x-x). This then works together with a control device known per se in the sense that the temperature of the surface (49) to be cleaned is optimally set in accordance with a predetermined cleaning or care program and / or the type of floor covering.
