Definitions

  • the invention relates to a mobile floor cleaning device with a tank integrated in a housing for fresh cleaning liquor and, if appropriate, a tank for dirty water and a suction nozzle for dirty water arranged behind the housing in the direction of travel and at a fixed distance therefrom Housing is connected.
  • a separate tank for dirty water is provided if the dirty water is not after an internal treatment, e.g. B. Filtration, is returned to the tank for fresh cleaning liquor.
  • the dirty water tank can be omitted.
  • Such devices are known as spray extraction devices for carpets or, if they are provided on the bottom with a rotating brush and a nozzle spraying the cleaning liquid in the area of the brush, as a floor scrubbing machine or automatic cleaning machine.
  • the cleaning machine is a self-contained combination of a universal cleaning machine and a water vacuum cleaner.
  • the floor covering is scrubbed with a cleaning liquor in one operation and then vacuumed off.
  • the spray extraction device works similarly, but there is no scrubbing.
  • the fresh cleaning liquor is filled into the tank provided for this purpose.
  • the so-called working solution In order to achieve an optimal cleaning result, it is necessary to optimally adjust the concentration of the liquor, the so-called working solution. This can be done in two different ways.
  • dosing the detergent manually the ratio of water to the cleaner concentrate must be calculated.
  • the metering or measuring should be done using a measuring cup.
  • the detergent concentrate doses There is a risk of underdosing or overdosing. In both cases, a poor cleaning result is achieved.
  • overdosing streaks and streaks form on the floor surface; the underdosing only enables insufficient dissolving of the dirt.
  • a second dosing option is to fill the floor cleaning devices with a central dosing station. This is usually built up in a stationary manner and is often located in the cleaning room and / or in the basement. For filling, the canister with the cleaning concentrate is connected to the dosing system and the working solution mixed with water is poured into the floor cleaning device. Since the often very long distances to the dosing station have to be covered each time the solution is refilled, this handling is cumbersome and consumes a lot of time. This applies in particular to cleaning devices in which the dirty water solution is not reprocessed and returned to the tank for fresh cleaning liquor. But also for cleaning devices with a traceable cleaning liquor, because of the consumption of the liquor, it is necessary from time to time to drive to the dosing station and fill in freshly prepared cleaning liquor.
  • a spray extraction device is also known from US Pat. No. 3959844, in which the use solution is prepared by mixing water and cleaner concentrate within the device.
  • the invention is therefore based on the object of improving the floor cleaning device mentioned at the outset, so that an exact metering of the cleaning liquor is possible, but the time previously required for filling the tank for the cleaning liquor (set-up time) is considerably reduced, the device still remains compact, agile and flexible and can be used regardless of the water and / or sewage connection.
  • a metering system which is attached between the housing and the suction hose and has a metering device and mixer for cleaning concentrate and water, a storage container for the concentrate which is connected to the metering device and a water inlet connected to the metering device.
  • the dosing system is integrated in the cleaning device in a similar way as in US 3 959 844, but the maneuverability and compactness of the device is retained despite the relatively voluminous tank for the fresh cleaning liquor, since the dosing system together with the storage container for the cleaning concentrate between the housing and the suction hose is attached.
  • the known automatic cleaning machines there is an unused space at this point, so that the external dimensions of the cleaning device are not changed by the installation of the metering system and the cleaning device remains as compact and agile as before. No recesses are necessary in the previously known devices for installing the metering system, so that the devices already used are easily in place and can be retrofitted by the customer service technician without the cleaning device having to be sent back to the manufacturing plant.
  • a large number of different embodiments can be used as metering devices and mixers in the floor cleaning device according to the invention. This makes it possible to install a diaphragm pump which ensures exact meterability.
  • the metering device and mixer is essentially designed as a Venturi nozzle.
  • the Venturi nozzle which works on the principle of the water jet nozzle, requires no additional, for. B. electrical connection, is compact, practically maintenance-free and works very precisely even with changing water pressure. If interchangeable nozzles with different cross sections are provided in the concentrate suction hose, the floor cleaning device can be easily converted to different dilution ratios. For easy handling, it is advantageous if the different nozzles are identified by their color.
  • the metering system on existing fastening devices for. B. is attached to the mounting rails for the fresh water and waste water hoses. Retrofitting is then even more cost-effective and less time-consuming. A simple and quick refilling of the tank for the fresh cleaning liquor is possible if the water inlet is a connection piece provided for a plug-in coupling.
  • the tank has a drain hose
  • the outlet of the metering device and mixer be detachably connected to the drain hose.
  • An additional hole in the tank for fresh cleaning liquor is not necessary.
  • Another important advantage of the detachable connection directly to the already existing drain hose is the possibility of being able to use the metering system for other purposes and not only for the floor cleaning device. The dosing system can thus be removed quickly and easily from the respective cleaning device and mounted on other devices or also on a transport trolley which is often used in commercial cleaning processes.
  • the outlet of the meter and mixer be designed as a plug that can be clamped into the outlet-side opening of the drain hose.
  • FIG. 1 shows an automatic cleaning machine which is driven by a battery or cable and is suitable for the rational cleaning of medium-sized floor surfaces.
  • the tanks for fresh cleaning solution and dirty water are housed in the housing 1.
  • a handle bar 2 In the upper area of the device a handle bar 2, a locking bracket 3 and a control panel 4 (control panel) can be seen.
  • the space between the suction hose 8 and the back of the housing 1 is used according to the invention to accommodate a metering system.
  • the metering system 11 consists of a Venturi nozzle, to which the cleaner concentrate is conducted via a hose from a storage container 12.
  • the storage container 12 is fastened to the rear of the cleaning machine by means of a holder 13.
  • the metering system 11 can be connected to the water supply network via a connector 14 provided with a plug-in coupling.
  • the finished metered mixture passes through the hose 15 into the tank for fresh cleaning solution.
  • the machine only has to be moved to the next water connection and connected with a commercially available water hose with a plug-in coupling.
  • FIG. 2 shows a particularly preferred embodiment of the invention.
  • the metering system can be connected to the water supply network via a hose 17 with a suitable plug-in coupling 18.
  • the reservoir 12 for the cleaner concentrate is inserted into a holder 13 into which the metering system with the Venturi nozzle is integrated. This makes it easier to replace the dosing system and use it for other purposes.
  • the outlet of the metering system is connected via a further hose 15 to the end of the drain hose 10 of the tank for fresh cleaning liquor.
  • the hose 15 ends in a stopper 16 which is adapted to the opening width of the drain hose 10.

Abstract

Un réservoir de liquide de lavage frais et le cas échéant un réservoir d'eau sale sont intégrés dans un corps (1). Une buse (7) d'aspiration d'eau sale est monté derrière le corps (1), dans le sens de déplacement de celui-ci, à une distance fixe de celui-ci. La buse (7) est reliée par un tuyau flexible d'aspiration (8) à une admission d'eau sale du corps (1). Un système de dosage (11) comprenant un doseur et un mélangeur de produit concentré de nettoyage et d'eau, un réservoir (12) de concentré relié au doseur et une admission d'eau (14) reliée au doseur sont montés entre le corps (1) et le tuyau d'aspiration (8). On peut ainsi doser le liquide de nettoyage avec précision. Le temps habituellement requis pour remplir le réservoir de liquide de nettoyage est considérablement réduit. L'appareil est compact, facile à manier, mobile et utilisable sans raccordement pour l'alimentation en eau et/ou l'évacuation des eaux usées.
