Definitions

  • the invention relates to a cleaning device having a carrier body, a wiper plate arranged at a lower end of the carrier body for carrying a cleaning element arranged on at least one side of the wiper plate, a liquid tank for receiving cleaning liquid and a line system for supplying the cleaning liquid in the direction of the cleaning element via a pump device ,
  • Such a cleaning device may for example be part of a wiper system, wherein the cleaning device then as a wiper device, which is for example a floor wiper, may be formed.
  • a wiper device is known from DE10358467 A1.
  • This wiper device has a carrier body in the form of a handle, at the lower end of a wiper plate is provided, which is provided with a reference as a cleaning element.
  • the wiper device further comprises the liquid tank for receiving cleaning liquid, usually mixed with or without cleaning agent added water. Via a pump, which forms the pumping device, the liquid is sprayed through the conduit system in front of the surface, which is to be subsequently cleaned during the wiping movement of the cleaning element.
  • the known device allows to easily and easily provide fluid to solve even stubborn dirt.
  • the cleaning additives provided may be added to the cleaning liquid for this purpose.
  • the disadvantage of the known device is, on the one hand, that the cleaning liquid is sprayed in front of the cleaning element, which of course is only possible if sufficient space is available for this purpose. For corners and edges and under furniture, this can be difficult.
  • a particularly advantageous application of the invention consists in a wiper system, which is not designed as a complete wetting system, but are used in the substantially dry, only occasionally moistened cleaning elements.
  • a wiper system may for example have a mobile storage box with dry cleaning elements in the form of towels and a cleaning device according to the aforementioned type.
  • the storage box can be mounted on rollers, wherein the storage box and / or cleaning device can be designed such that the cleaning appliance can be coupled to the storage box.
  • the invention can also be used in conjunction with all other cleaning devices, for example, suction devices for windows or other surfaces, regardless of their orientation. Also in connection with classical wet wiping systems, the invention can be used. In all cases, however, there is the problem that when separate cleaning liquid is to be supplied to the cleaning element or before the cleaning element is to be applied to the surface to be cleaned, this cleaning liquid must be previously added with the required cleaning additive. Often, however, only minor parts of the surface will have contamination for which the cleaning additive is needed, or the surface will generally be smaller than the area that could be cleaned with the cleaning liquid present in the liquid tank.
  • the object of the invention is therefore to provide a cleaning device with the one hand, the cleaning is effective and easy, and on the other hand is easy to use.
  • the cleaning device has a metering system with at least one reservoir for a cleaning additive, wherein the metering system is designed such that it is able to add the cleaning additive of the cleaning liquid.
  • a system is now used in which cleaning additive can be supplied in a targeted manner via a metering system.
  • this could also be done by injections into the liquid tank.
  • the advantage of the invention is that the user always has a supply to cleaning additive is available, which he can choose and bring in the cleaning liquid.
  • the cleaning liquid is not already mixed in the liquid tank, but only in the line system with the cleaning additive. This eliminates the above-mentioned drawback that too much cleaning liquid is mixed with the cleaning additive, so that either the cleaning additive needs to be unnecessarily consumed or disposed of.
  • At least two reservoirs are provided for the provision of different cleaning additives.
  • This embodiment preferably has an adjusting device, via which the respective reservoir can be selected.
  • selecting means that a flow connection is established between the line system and the reservoir, so that the cleaning additive can be activated.
  • fluidic reducing agents in the line to the line system, the amount of cleaning additive can also be adjusted, if desired.
  • the respective reservoir can be connected to the pipe system of the supply for the cleaning liquid via lines.
  • the cleaning additive can also be introduced directly into the cleaning element via a separate distribution line.
  • the lines are preferably closed by valves, so that they can be selectively opened and closed especially when using multiple reservoirs.
  • these valves can also be used to control the volume flow which is introduced from the reservoir into the liquid flow of the cleaning liquid.
  • the valves are preferably formed by an adjusting device, which can be operated by the user from the outside.
  • This may, for example, be a sliding element which, in different positions, respectively leaves one of the lines running from one of the reservoirs to one connection to the conduit system of the cleaning liquid, while the other lines are closed, for example by being compressed by a blocking element.
  • all other forms of valves are possible, for example, via a sliding element in each case the closing means of a separate valve can be transferred from the open to the closed position and vice versa.
  • all lines can be closed or opened separately, which makes it possible in particular to use a mixture of cleaning additives.
  • a cleaning additive that increases the cleaning efficiency or is used as a solvent, for example, for grease.
  • another cleaning additive for example, could be used exclusively for aromatizing the cleaning fluid.
  • a mixture adapted to the cleaning element can also be used, so that, for example, a solvent-containing material is used in a rather abrasive coating, while a pure aromatic substance is admixed to a soft, polishing coating.
  • the adjusting device is thus preferably designed such that in each case at least one cleaning additive stored in an active reservoir can be added via the dosing system of the cleaning fluid, while one or more further cleaning additives kept ready in passive reservoirs are prevented from being supplied to the cleaning fluid.
  • This can be done via the slide already described as Einsteilvorraum.
  • Controlling and adding the cleaning additives, if they are liquid, can also be done via the flow dynamics of the cleaning liquid.
  • a portion of the conduit system may be formed with a Venturi nozzle, so that the negative pressure generated in this nozzle is able to suck the cleaning additive automatically.
  • the metering system may also have a metering pump which actively pumps the liquid cleaning additive into the line system.
  • This metering pump can either be operated separately by an operating means by the user or be coupled in their operation with the pumping device for the cleaning liquid.
  • the pumping device for the cleaning fluid may be formed by a manually operated pump whose pump body is moved via a Bowden cable or other traction means.
  • a corresponding actuating means may be provided on the handle of the cleaning device.
  • Such an actuating means may be a lever through which the Bowden cable can be tightened. At the same time, this movement can also be coupled to the movement of the pump body of the metering pump.

Abstract

L'invention concerne un appareil de nettoyage (4) comportant un corps de support (5), une plaque d'essuyage (4) agencée à l'extrémité inférieure du corps de support (5) et portant un élément de nettoyage (11) agencé sur au moins une face de la plaque d'essuyage (4), un réservoir de liquide (2) logeant un liquide de nettoyage, et un système de conduite acheminant le liquide de nettoyage en direction de l'élément de nettoyage (11) par l'intermédiaire d'un système de pompe. Les dispositifs de nettoyage connus ont pour inconvénient que des additifs de nettoyage éventuels doivent être ajoutés dans le réservoir de liquide (2), au prix d'une plus grande complexité et avec pour inconvénient que la totalité du liquide doit alors être mélangée à l'additif de nettoyage. L'invention y remédie en ce que l'appareil de nettoyage (4) présente un système de dosage muni d'au moins un réservoir d'additif de nettoyage, le système de dosage étant conçu de telle manière qu'il peut ajouter l'additif de nettoyage au liquide de nettoyage.
