Definitions

  • the present invention refers to a device for cleaning or treating a floor, a filling station for dispensing a liquid for cleaning or treating a floor into a reservoir of a device for cleaning or treating a floor, wherein the device and the station can be coupled, a system for cleaning or treating a floor comprising said device and said station and a method of filling or refilling a reservoir of a hand-operated cleaning device.
  • the cleaning implement For cleaning or treating a surface, in particular a floor, the cleaning implement has to be charged repeatedly with the cleaning or treatment composition to be applied. Thus, there has to be provided a possibility to recharge the cleaning implement.
  • the cleaning personnel In particular when professionally cleaning or treating floors, which means for example cleaning or treating a comparatively large area in total or cleaning or treating a lot of floors which are spread in comparatively large building like an office building or a public or private institution, the cleaning personnel often has the problem that recharging of the implement for cleaning or a treatment is circumstantial or time consuming. This is because typically the cleaning personnel either has to take the container which stores the cleaning or treatment composition and which often is heavy and/or bulky with him or her or he or she has to return to the container each time he or she desires to recharge the cleaning implement.
  • cleaning implements which have a reservoir for storing and releasing the cleaning or treatment composition, which the cleaning personnel takes with him or her or which is attached to or integrated within a handle of a cleaning implement.
  • US 6,550,998 B1 discloses one example for a device for applying flowing media to a surface, wherein the device comprises an equipment for a container, which can be worn on the back of the person applying the media.
  • the device has a flow-regulating hose which can be shut off for conveying the media from the container by force of gravity to an outlet on a mopping or applicator device.
  • the container is equipped with a filling opening which is suitable for the pouring in of the media without a funnel or a similar means and is closable by a closure lid.
  • the hose connecting the container with the mopping or applicator device may be very disturbing during the cleaning or application process since it may hinder the freedom of movement of the cleaning person and he or she always has to be taken care that it won't get caught and that it isn't torn off.
  • a device having a reservoir mounted to the handle is for example known from DE 3718141 A1 .
  • This document describes a container for liquid floor treatment preparations adapted to be mounted at its back to the handle of a long-handled floor wiper.
  • the container includes a return flow cutoff funnel with an inlet, and a lower outlet tube with an exit port coupled to one end of a flexible hose that is selectively kinked to prevent fluid flow from the container to the floor, or un-kinked to obtain such fluid flow.
  • the container is filled manually via an opening functioning as a filling hopper.
  • a further cleaning implement is disclosed in US 5,736,620 .
  • This document describes a cleaning tool having a multipurpose implement mounted within a housing, wherein housing and implement again are mounted to an extendable handle.
  • a liquid container or reservoir is mounted so as to form a portion of the handle so that liquid may be selectively dispensed through the handle to a distribution header in the housing.
  • the container has a thread throat portion through which liquid may be resupplied to the interior of the container and to which a closing cap is threadingly engaged.
  • a further document which discloses a chamber for holding a liquid within the handle of a cleaning implement is US 6,467,983 .
  • the handle of said cleaning implement includes internal upper and lower valve assemblies sealably mounted within the handle to provide an air tight chamber there between for holding liquid.
  • the upper valve assembly includes a push button actuator for introducing air into the chamber.
  • the lower valve assembly includes a dispensing outlet for discharging the liquid from the chamber.
  • the upper valve body is preferably manually removable from the tubular shaft of the handle to facilitate filling of the chamber with liquid.
  • DE 299 03 868 U1 describes a device for cleaning or treating a surface, comprising a handle provided with a reservoir (4) for storing a liquid, an implement for cleaning or treating a surface and a valve (5) provided at the outer wall of the reservoir (4) for dispensing the liquid to be discharged from the reservoir onto the floor to be treated.
  • an object of the present invention to find a way to overcome the above described disadvantages and in particular to facilitate the filling or refilling of such a reservoir and, thereby, to accelerate the cleaning process as a whole.
  • the above problem is solved by providing a method of filling or refilling a reservoir which is mounted to or part of a device, especially a hand-operated device for cleaning or treating a surface, in particular a floor, with a liquid, comprising positioning a tank containing the liquid to be filled or refilled and the reservoir to be filled or refilled in such a position that the liquid level in the tank is at the same height or below the maximum filling level of the reservoir to be filled or refilled, providing a connection between the tank and the reservoir in a position which enables a flow of the liquid from the tank into the reservoir and initiating the flow of the liquid from the tank to the reservoir through the connection, wherein the reservoir to be filled or refilled is the reservoir (2) of the device according to claims 1 to 8 and the foule (7) is fixed to the filling station according to claims 9 to 24.
  • the device may be any device which has a reservoir mounted thereto or incorporated therein.
  • a "hand-operated device for cleaning or treating" in the sense of the present invention may be any had-operated device for cleaning or treating a surface which is known in the art, in particular a handle-type cleaning/treatment device.
  • the "height" of a filling level or a liquid level refers to the vertical distance from the ground to the filling level or the liquid level, respectively, if not otherwise indicated.
  • the maximum filling level may be identical with the upper edge of the reservoir. However, it is also possible, for example for constructional reasons, that the maximum filling level is below the upper edge of the reservoir.
  • Liquid in the sense of the present invention means any substance which is capable of free-flowing, i.e. it moves through the components used in the method of the present invention without needing any further support, like the use of pumps, in a suitable time to not render the filling process inefficient.
  • Communicating tubes are considered to be tubes which may be of different shape but have an open end and are connected with each other. In case they are filled with a substantially homogenous liquid the liquid level in each of the tubes is the same provided that the diameter of the tube is not so small that for example the capillary force in the tube distorts the effect of the gravity and the atmospheric pressure, and provided that for each tube the connection is positioned below the liquid level at equilibrium.
  • the filling of the reservoir proceeds because the liquid levels of those connected containers are different and the system seeks to eliminate this imbalance.
  • the liquid flows from the tank into the reservoir until the liquid levels of the tank and the reservoir have the same height.
  • connection at the tank preferably is provided near or even more preferred at the lowest point of the tank, which typically corresponds to the bottom of the tank or the top of the tank if the tank is positioned upside down.
  • connection at the reservoir preferably is provided below the above mentioned lowest point of the tank. Thereby, the amount of liquid which remains in the tank and may not be transferred into the reservoir is reduced.
  • the position of the connection at the reservoir should be below the maximum filling level of the reservoir to allow a stop of the filling before the liquid runs over the edge of the reservoir. Otherwise, the position of the connection is not specifically limited in order to take advantage of the above described filling concept.
  • a ventilating means should be provided with the tank as well as with the reservoir to enable air to escape from the reservoir and to flow into the tank, respectively. Otherwise the increasing overpressure in the reservoir and the negative pressure in the tank may prevent the filling of the reservoir.
  • the means for ventilation of the reservoir is provided at the same height or above the reservoir maximum filling level
  • One big advantage of filling or refilling the reservoir according to the method of the present invention is that the filling or refilling proceeds automatically as soon as the connection between the tank and the reservoir is provided. The cleaning person only has to initiate the flow by providing said connection.
  • the discharge of the liquid from the tank into the reservoir automatically stops when the liquid level in the reservoir reaches the height of the liquid level in the tank. Since the reservoir and the tank are positioned such in relation to each other that the liquid level in the tank is at the same height or below the upper edge of the reservoir, the transfer of the liquid from the tank into the reservoir stops at the latest when the liquid level in the reservoir reaches the upper edge of the reservoir. Thus, there is no danger that the liquid runs over the upper edge of the reservoir and gets lost, even when the top of the reservoir is open.
  • the cleaning personnel only has to provide the connection between the tank and the reservoir and shortly thereafter, depending on the volume of the reservoir to be filled or refilled, the cleaning or treatment implement can be used for the next area to be cleaned or treated.
  • the cleaning or treating person may use the time until the filling or refilling of the reservoir is completed to do other things he or she has to do, like polishing or drying the already cleaned or treated surface, cleaning or treating other surfaces with other devices or, in case the device for cleaning or treating a surface and the tank both are fixed to a movable cart, the cleaning person may use the time to move the cart to the next surface to be cleaned and, generally, the device for cleaning or treating will be ready for the next application when said next surface is reached.
  • the method according to the present invention helps to reduce the loss of liquid actually intended to be applied onto a surface, which may occur in the process of filling or refilling the cleaning/treatment device. Moreover, the method according to the present invention is also time saving.
  • the device for cleaning or treating a surface and the tank are removably fixed during the filling or refilling process such that the tank and the reservoir may not be moved, for example by the cleaning person, into a position in which the height of the liquid level of the tank is above the maximum filling level of the reservoir and the filling will not automatically stop when the reservoir is full.

  • the fixing proceeds such that the maximum filling level of the reservoir is at the same height or above the liquid level in the filling station, when the valve cooperates with the filling station.
  • fixing means any means known in the art may be used.
  • the fixing takes advantage of the coupling system such that the part of the coupling system which is a part of the filling station is fixed to the filling station and the remaining part of the coupling system which is provided at the reservoir can be coupled. Thereby, at the same time the coupling generates the cooperation between the reservoir and the filling station and fixes the device to the filling station.
  • the means to enable the liquid to be discharged from the reservoir directly or indirectly to the floor can be any means which is known from the devices of the state of the art.

  • the liquid may directly be applied from the opening of the reservoir to the floor, for example as is the case in the device described in DE 37 18 141 A1 .
  • the liquid is conveyed indirectly to the surface to be treated. This may be realized, for example, when at first the liquid is conveyed from the reservoir to the implement for cleaning or treating the surface and then applied to the surface, like in the devices of US 6,467,983 B2 and US 5,735,620 .

  • valve represents one part of a coupling system it may not only be coupled to the cooperating part of the coupling system provided at the filling station but also to an analogous part of a coupling system which enables to discharge the liquid from the reservoir to the surface.
  • the way of the liquid from the reservoir to the surface is also not completely identical with the way of the liquid from the valve to the reservoir when filling the reservoir since the liquid has to pass a different coupling system to become discharged. Consequently, in such a system the means is also different from the valve and, therefore, such a discharging/filling system is supposed to be within the scope of the present invention as well.
  • valve is closed the whole time when there is no cooperation between the valve and the filling station. It is particularly preferred that the means for discharging the liquid from the reservoir to the surface to be cleaned is completely separated from the valve.
