Definitions

  • the invention relates to a cleaning system with two metering devices, in particular for use in hygienically sensitive areas such as healthcare facilities and clean rooms.
  • mop covers are used, depending on the area of application, which are either brought dry and clean to the place of use and moistened to the correct extent on site or which are already pre-moistened to the correct extent transported to the place of use, the latter in a closed container.
  • the correct dosage of the cleaning fluid on the mop cover is of great importance, since too little cleaning fluid as well as too much cleaning fluid leads to unsatisfactory cleaning and endangers the maintenance of / compliance with disinfection measures.
  • metering systems including those suitable for clean rooms, which have detergent reservoirs from which a certain amount of cleaning solution is reproducibly dispensed in one way or another. These are usually carried on a mobile cleaning system trolley, together with containers for fresh mops, containers for used mops and other consumables.
  • on-site dosing systems those are known which are arranged in a container filled with cleaning liquid and which, when actuated, lift a certain amount of liquid above the liquid level and make it available for contact by a mop cover pulled onto a mop holder.
  • Other metering systems of this type dispense a certain amount of detergent, driven by gravity in particular, with a further container in the manner of a collecting tray usually being located under the detergent reservoir.
  • the amount of cleaning agent that is pulled on is carried out in that the amount of cleaning agent either flows directly onto a mopping cover located under a corresponding outlet and from there, if necessary, into the collecting tray, or indirectly by first releasing the amount of cleaning agent into the collecting tray and then picking it up from there.
  • cleaning solutions used in commercial cleaning differ in their properties depending on the surface to be cleaned or, depending on requirements, in their chemical composition and their chemical and physical properties.
  • cleaning solution is therefore initially understood here to mean all types of such liquids.
  • surfactant solutions it also includes disinfectant solutions.
  • the present invention is therefore based on the object of specifying a cleaning system in which different cleaning solutions carried along can be used separately as required without contamination.
  • a cleaning system having a cleaning trolley and at least two storage containers arranged thereon for one cleaning liquid each, each storage container having a metering device for dosing cleaning liquid, the storage containers being spatially separated from one another so that a dosing process by means of a storage container does not occur a contamination of a dosing process by means of the other storage container is leading.
  • the invention provides such a spatial separation of the dosing devices on a cleaning trolley that contamination, for example through splashes, is excluded.
  • This is achieved according to the invention, for example, by providing a spatial barrier between the two metering devices, which are implemented as a partition, stack of containers or simply by providing a splash-proof distance between the two metering devices.
  • this can be achieved, for example, by an arrangement front-rear, right-left, diagonally offset or in front of a handle part on the cleaning trolley.
  • the invention is also a storage container separated by a partition into two storage container chambers, the two chambers of which each have their own metering device.
  • the invention provides for the volume of detergent dosed by two separate dosing devices to be kept separate even during the dosing and application process on a mop cover.
  • a collecting container is assigned to each storage container, the collecting containers being designed spatially separated in the same functional manner as the storage containers, each collecting container being arranged below an assigned storage container.
  • At least one metering device has a pipe section connected to a storage volume of the storage container and a pipe section movable in this has guided hollow piston, wherein a cavity of the hollow piston located in a first position is accessible from the storage volume and the cavity of the hollow piston located in a second position is connected to the surroundings of the metering device, the hollow piston two being spaced apart from one another by means of a spacer Has end covers that define a metering volume between them, the spacer being designed as a cylinder jacket section and / or as one or more webs, wherein the webs are furthermore preferably connected to one another and / or divided one or more times in their longitudinal axis and / or with an end cover connected are formed.
  • a hollow piston to be a piston which, between an upper and a lower end, has an intrinsic volume which is not filled with material and which is movable with it.
  • a piston does not necessarily have a side wall and certainly not a closed side wall, as would be formed, for example, by a lateral surface of a cylinder, since such side walls with the same functionality can also be formed by the component in which the hollow piston is movable.
  • Such a hollow piston is structurally simple, highly functional and, with its own volume, provides a closed space for receiving a cleaning solution, which is accessible by moving from a first to a second position for the entry and exit of the cleaning solution.
  • the dosing volume eliminates the risk known from the prior art of overdosing or underdosing of cleaning solution on the mop cover, as is the case with valve-opened outflows of cleaning solution reservoirs through pressure plates operated by the user. Since this metering device can preferably be operated purely mechanically, electrical drives with a corresponding need for a voltage supply avoided with advantage. Because the cavity is only accessible from the storage volume in a first position, undesired emptying of the storage volume is advantageously avoided, since it is not in contact with the storage volume in any other position. Only in the second position is the cavity connected to an environment, so that the storage volume is closed in this position, at least not connected to an environment via the hollow piston. In this second position of the hollow piston, the storage volume is preferably designed to seal off from the environment.
  • this hollow piston has at least two chambers, in particular chambers which are azimuthally separated, different dosing is possible depending on the setting of the dosing device. If the chambers have different volumes, a corresponding setting leads to the emptying of a single chamber or two or more chambers.
  • an actuating element acting on the hollow piston is provided, in particular a mechanically acting actuating element, preferably a purely mechanically acting one, the actuating element being arranged in or on the associated collecting container.
  • a mechanically acting actuating element preferably a purely mechanically acting one, the actuating element being arranged in or on the associated collecting container.
  • Such an actuating element is designed to move the hollow piston from one position to another. This one position can be the described first or the described second position, this other position then being the respectively remaining described position.
  • the actuating element moves the hollow piston from the second, the rest position, into the first position, the filling position, and then, driven by gravity, it returns to its starting position Movement is designed to slide back. In this case, only one movement is actively carried out by a user.
  • the hollow piston movement is completely driven by the actuating element, that is to say this is designed to move the hollow piston from one position to the other and back.
  • actuating elements for example a shaft guided under a bottom of the storage container, which ends on the side of the storage container in a handwheel or lever or handle that can be operated from there and which has, for example, a cam in the area of the hollow piston with which a force is applied to the same is transferable.
  • an actuating element is arranged in or on the associated collecting container, the actuating element having an active end acting on the hollow piston and an actuating end, the collecting container preferably being designed at a distance from an end of the pipe section remote from the storage container.
  • the actuating element is arranged in or on the associated collecting container, in particular articulated, the actuating element having an active end acting on the hollow piston, the collecting container preferably being designed at a distance from an end of the pipe section remote from the storage container, this is secure with a mop holder Operable mop cover.
  • the drop height is preferably selected so that splashing is prevented as much as possible, reinforced by appropriate dimensioning of the collecting container and its side wall heights or by the provision of a baffle plate or the like.
  • the actuating element is designed as a rocker arm.
  • a rocker arm can also be implemented in a structurally simple manner, is operationally safe and easy to clean, in particular it can be autoclaved.
  • the collecting container has at least one, preferably two or four locking lugs on its inside, the locking lugs in particular being arranged on two opposite side walls of the collecting container, the actuating element being reversibly lockable on the at least one locking lug , in particular reversibly lockable with a positive fit, and / or the at least one latching lug is designed as a movement stop for the actuating element.
  • the at least one latching lug a positive, reversible locking of the actuating element is advantageously realized without a great deal of additional expenditure in terms of material or assembly costs.
  • the at least one locking lug, which protrudes into the interior of the collecting container is essentially defined by curves.
  • the actuating element Due to this configuration and the low rigidity of the collecting container compared to the rigidity of the actuating element, it is possible to transfer the actuating element into a locked position without further movable elements. Due to the force of gravity, the actuating element is held on one side of the locking lug after the transfer until a force potential, which is defined by the relative force to be exerted on the side wall of the collecting container to bend the side wall and thus release a degree of freedom of the actuating element, is exceeded. The more latching lugs that come into engagement when the actuating element is locked, the greater the force to be overcome to release the actuating element.
  • the ratio of forces behaves as it were when the height or the length of the at least one locking lug protruding freely into the space increases, since this is the case a greater bending of the side wall of the collecting container or bending of the nose around against its longitudinal axis is necessary.
  • An optimal balance of forces between reliable locking of the actuating element and a user-friendly effort to release the actuating element is achieved through the use of two locking lugs.
  • Two further locking lugs are designed as a movement stop for the actuating element, so that if the actuating element is released from its locking position, it has only a limited radius of motion to prevent the actuating element from pivoting out excessively and thus in unclean work, especially in the clean room.
  • the active end can be locked at least indirectly by the at least one locking lug in a first position, the active end holding the hollow piston in its first position in this first position. It is possible to lock the active end directly on the at least one latching lug, or to indirectly lock the active end at a different position within the actuation element due to the essentially rigid design of the actuating element as a rocker arm. Such a locking is particularly advantageous because when a user releases the actuation end, the cleaning liquid located in the hollow piston is retained by the hollow piston connected to the active end and is therefore not discharged into the collecting container. Contamination of the cleaning liquid due to not being used immediately is thus prevented in a distributed manner, as is possible spillage caused by moving the cleaning device.
  • a second actuating element is arranged on the storage container, wherein the second actuating element is releasing the active end and the hollow piston from their respective first position when actuated.
  • the second actuating element is advantageously a purely mechanical one in order to make the cleaning trolley as simple as possible and thus less prone to failure.
  • the second actuating element is intended to enable the active end and the hollow piston to be released from their respective first position, if possible without the user having to exert excessive force. It is therefore advantageously provided that the release force of the user can be introduced vertically into the active end via the hollow piston, since a release movement of the hollow piston also runs in this direction.
  • the second actuating element is designed with a lower and an upper sub-area, the two sub-areas being connected to one another in a force-locking, form-locking or material-locking manner.
  • an introduction of the release force via a lever construction one end of the lever construction engaging the hollow piston and another end being accessible to a user in an actuating manner.
  • the second actuating element is designed as an electrical actuating mechanism which can be operated by means of an accumulator or a battery and controlled by means of buttons, switches and / or remotely by means of a batteryless radio transmitter.
  • the wireless remote control of the electrical actuating mechanism can be implemented according to the invention, for example by means of 2.45 GHz or 433 MHz radio, Bluetooth, NFC or RFID.
  • the batteryless radio transmitter can be attached to a mop handle, for example, so that the cleaning liquid can be introduced into the collecting container optionally up to 300 m away by a user, so that the user immediately receives the correct amount of cleaning liquid to take up on his mop cover when he arrives at the invention finds.
  • At least one further container is arranged between the collecting containers of the dosing systems, in particular for receiving used mop covers.
  • the arrangement of containers with fresh mop covers between the dispensing systems with collecting containers it is irrelevant in the case of containers for holding used mop covers whether or not splashes of cleaning solution get into them. If the walls of the container are sufficiently high, fresh mop covers can of course also be carried, which are then protected from contamination by splashes.
  • the collecting containers on the cleaning trolley are arranged on opposite sides or offset diagonally. Ease of access must be observed and given in all cases.
  • the storage containers, metering devices, collecting containers and / or actuating elements are at least partially made of a plastic or a high-alloy steel, in particular stainless steel. This means that they can be autoclaved and are particularly suitable for clean room cleaning.
  • Fig. 1 shows a cleaning system according to the invention.
  • the cleaning system comprises a conventional cleaning trolley 1, two storage containers 2, 3 each with a metering device 4, 5 and each a collecting container 6, 7.
  • the storage containers 2, 3 are designed separately from one another in such a way that the respective contents do not come into contact with one another and contaminate each other's content. In particular, they are spatially separated.
  • a metering device 4, 5 is arranged on each of the storage containers 2, 3, by means of which a certain, possibly also adjustable, amount of the cleaning agent from the corresponding storage container 2, 3 is metered.
  • the cleaning agent emerging from the storage containers 2, 3 arrives in a collecting container 6, 7, which are also spatially separated from one another in accordance with the separation of the storage containers 2, 3.
  • a further container 20 is arranged between the collecting containers 6, 7, for example for receiving used mop covers.
  • an actuating element 17 is arranged, which can be actuated by applying a force.
  • the actuating element 17 has a rocker arm 19 which can be actuated by a user without hand contact through a mop cover pulled onto a mop holder.
  • the actuating element 17 is coupled to a transverse rod and a further lever, the active end 17 of which is a piston of the metering device 4, 5 linearly displaceable.
  • the collecting containers 6, 7 each have inner sides 22 with side walls 24.
  • Fig. 2 shows a preferred embodiment of the hollow piston 9 of the metering device according to the invention.
  • the hollow piston 9 is in the operating state in the in Fig. 2 not shown pipe section mounted linearly movable.
  • the hollow piston 9 has a cavity 10 which is divided into a first chamber 15 and a second chamber 16.
  • the cavity 10 is formed by two end-face covers 12, 13 and a spacer 11, which is designed as webs 14 in the example shown.
  • the upper end cover 12 is designed due to the enlarged radius in such a way that it delimits a linear movement of the hollow piston 9 together with the bottom of a storage container.
  • the webs 14 delimit and define the chambers 15, 16.
  • the illustrated embodiment has a third chamber, which is covered by webs 14 in the illustration and which differs in volume from the other chambers 15, 16.

  • the opposite side walls 24 each have two locking lugs 23 on, wherein a pair of opposing locking lugs 31, 32 is arranged in an identical position within the respective side wall 24.
  • the four latching lugs 23 are identical to one another and essentially have a lug-like rounded curvature which protrudes into the interior of the collecting container 6.
  • a smooth sliding of the actuating element 17 over the latching lugs 23 is made possible.
  • the actuating element 17 is reversibly locked with a positive fit by the first pair of latching lugs 31.
  • the actuating end 21 is in its position closest to the collecting container bottom 28, so that the introduction of a cleaning mop into the collecting container 6 is not hindered and the active end 18 rests against the hollow piston 9.
  • the hollow piston 9 is also in operative connection with a lower sub-area 26 of the second actuating element 25.
  • the lower sub-area 26 is essentially cylindrical in shape, its length being significantly greater in relation to its diameter.
  • the lower sub-area 26 is followed by an upper sub-area 27 of the second actuating element 25, which is also essentially cylindrical, but its ratio between length and diameter is close to 1.
  • the upper and lower sub-areas 26, 27 are materially connected to one another so that the force introduced by a user on the upper sub-area 27 is transmitted directly to the lower sub-area 26 and accordingly, if the hollow piston 9 is in its first position, directly to the hollow piston 9. Furthermore, the upper sub-area 27 is formed outside the first storage container 2 and the lower sub-area 26 is embodied within the first storage container 2.
  • the first storage container 2 has an opening 30 on its upper side 29, within which the lower partial area 26 is slidably mounted.
