Abstract
The present invention relates to an apparatus for a cleaning carriage (2, 102) for rinsing, cleaning and wringing out a mop. More precisely, the apparatus comprises a mop container (6, 106, 202) having connecting sidewalls, a mop-wringing device (14, 50, 116), and also a collecting bowl (24, 52, 124, 200) arranged at the mop container to which cleaning agent is added through a separate vessel for rinsing and cleaning of the mop in the collecting bowl, the collecting bowl (24, 52, 124, 200) comprises liquid-sealed interfaces such that cleaning agent can be filled up in the collecting bowl for rinsing and cleaning of the mop, and also that devices (32, 66, 166, 206; 36, 56, 122, 172, 210) are arranged in connection to the collecting bowl for emptying of the same. The present invention also relates to a method and a use.
Description
- The present invention relates to an apparatus for a cleaning carriage for rinsing, cleaning and wringing out a mop. The present invention also relates to a method and a use.
- When scrubbing floors in public premises, working premises, restaurants etc., for example, use is often made of a cleaning carriage (equipped with wheels) having a bucket for a cleaning agent and in connection above the bucket a wringing device for wringing out liquid of a mop, swab or the like (fixed to the end of a shaft). Liquid that is squeezed out of the mop is returned to the bucket with the cleaning agent.
- The scrubbing is usually carried out such that the mop, following a scrubbing of a certain area of floor, is soaked in the liquid in the bucket. Subsequently the mop is placed in the wringing device, whereby excess liquid in the mop is pressed out. Possibly also wringing of the mop occurs, even directly after scrubbing of a certain area of floor and before soaking (particularly when the mop is used for drying/sucking up spilled out liquid from the floor). Liquid pressed out of the mop, then often dirty liquid, is thus returned back continuously to the same bucket that initially contained cleaning agent. Especially when scrubbing is carried out in publicly availably premises, the liquid in the bucket becomes contaminated very fast. Even the swab in itself becomes polluted.
- An obvious solution is instead to use two vessels, one for wringed out dirty water and one with unpolluted cleaning agent for soaking of the mop. However, one problem is that the consumption of cleaning agent becomes large, which results in a larger environmental load and increasing working hours for emptying and refilling. Besides, the cleaning agent is contaminated, in that the wringed out but still dirty mop is dipped in the vessel having the cleaning agent, whereby the mop precipitates dirt and contaminates the cleaning agent. Yet another problem is that the cleaning carriage remains unused for longer periods with cleaning agent in the vessel, whereby the cleaning agent evaporate (that is, in the cases use is made of volatile solvent).
- According to U.S. Pat. No. 4,174,977, a cleaning carriage is previously known which comprises a mop-bucket in which a net-basket is arranged, a container for collected wastewater and a container with cleaning agent from which liquid can be added the net-basket for rinsing and cleaning of a mop placed in the net-basket. The soaked mop is wringed out with a conventional wringing device. Cleaning agent that rinses the mop is partly sucked up by the mop, but a substantial amount is flowing on, through the openings in the net-basket, directly down to the wastewater container.
- One object according to the present invention is to provide an apparatus at a cleaning carriage for rinsing, cleaning and wringing out a mop, where the amount of cleaning agent for rinsing and cleaning of the mop can be reduced to a minimum and thereby achieving a decreasing environmental load. Yet an object is to provide a simple control, for example with foot or hand in order to rinse, clean and wring out the mop with a limited amount of cleaning agent. Yet another object is that the apparatus should be simple and cheap to produce.
- This object is achieved with an apparatus at a cleaning carriage for rinsing, cleaning and wringing out a mop according to the present invention, where the apparatus comprises a mop container having connecting sidewalls and a mop-wringing device arranged in the mop container. Further, the apparatus comprises a collecting bowl arranged at the mop container for rinsing and cleaning of the mop. Cleaning agent is added through a separate vessel to the collecting bowl for rinsing and cleaning of the mop. The collecting bowl comprises liquid-sealed interfaces such that cleaning agent can be filled up in the collecting bowl for rinsing and cleaning of the mop. Devices are arranged in connection to the collecting bowl for emptying of the same.
- An advantage with this solution according to the invention is that a relatively small amount of cleaning agent can be filled up and retained in the collecting bowl, but a sufficient amount in order to soak and rinse the mop since the collecting bowl can retain the liquid. The degree of utilization of cleaning agent can be more effective and contaminated liquid which is removed from the floor, ends up in a separate container which not is contact with the mop or the floor again, whereby the environmental load decreases.
- The collecting bowl comprises a bottom and connecting sides around it, where all surfaces are closed and liquid sealed, such that cleaning agent can be retained there, at least during a temporary period without any larger liquid losses, in order to once or during repeated times be able to rinse the mop. The collecting bowl, the mop container, and also remaining details on the cleaning carriage are suitably substantially in plastics or stainless steel.
- The collecting bowl is arranged to means that provide for emptying of liquid that is collected in the collecting bowl, usually contaminated liquid which is emptied in a waste liquid bucket below the mop container.
- Said means for emptying liquid in the collecting bowl can, according to an embodiment, comprise of one or several outlet valves arranged at the bottom of the collecting bowl.
- Preferably, said means for emptying of liquid in the collecting bowl, according to a preferred embodiment of the present invention, may comprise an axis of rotation to which the collecting bowl is rotatably arranged, the axis of rotation is arranged in the mop container whereby the collecting bowl is arranged to be angled down so as to pour out contaminated cleaning agent in the collecting bowl. Owing to the function that the bowl can be angled down for empty out of used cleaning agent, a structure is achieved that simply can be adapted to existing and modern cleaning carriages. The angling of the collecting bowl can for example be controlled by a foot pedal or the similar (foot pedal for controlling of wringing devices exists on some modern cleaning carriages) via a linkarm system.
- The present invention also relates to a method for rinsing, cleaning and wringing when scrubbing, during use of an apparatus at a cleaning carriage according to claim1, where the method comprises the following steps of:
- i) filling cleaning agent in the collecting bowl;.
- ii) soaking and rinsing of the mop in the collecting bowl;
- iii) wringing out the mop by activation of the wringing device; and
- iv) simultaneously with stage iii), or in a subsequent stage draining the liquid from the collecting bowl.
- The present invention also relates to a use of an apparatus at a cleaning carriage according to claim1, at a cleaning carriage for rinsing, cleaning and wringing out a mop.

In themop container 106 is a mop wringing device arranged, comprising amovable wall 116, movably arranged in a horizontal joint inside themop container 106 and further arranged to afoot pedal 134 via alinkarm system 122.Foot pedal strut 135 is rotatably arranged in a joint 136 in a position under thechassis 137 of the cleaning carriage to ahandle strut 139. Further is in the mop container 106 a collectingbowl 124 arranged, in which a sufficient amount of cleaning agent can be poured in to soak, rinse and clean the mop. Cleaning agent is added via aseparate vessel 126 via avalve 128 and aline 130 to the collectingbowl 124. The collectingbowl 124 is rotatably arranged around an axis ofrotation 132 at themop container 106. When wringing out the mop themovable wall 116 is influenced, via thefoot pedal 134, in direction against anopposite sidewall 138 in themop container 106. Simultaneous the collectingbowl 124 is pushed, during simultaneous rotation around the joint 132, through an opening in thesidewall 138 whereby the collecting bowl 125 is angled/tipped down such that contaminated cleaning agent in the collecting bowl is emptied below 140 themop container 106, preferably in a bucket or the similar for polluted/dirty liquid. By the described design of the cleaning carriage where thefoot pedal strut 134 is jointed arranged to thehandle strut 139 in a position below thechassis 137 of the cleaning carriage, installation and removal of a vessel for polluted liquid is facilitated at thearea 140 under themop container 106. By the way of placing thevessel 126 for cleaning agent on a plane of ashelf 142 above themop container 106, alarge space 144 is achieved under the cleaning agent vessel where cleaning equipment or the like can be stored. Thevessel 126 for cleaning agent may suitably be a separate container that only is fixed to the plane of theshelf 142 via thevalve 128 at the bottom of the cleaning agent vessel. In this way a simple structure is achieved for loading and unloading of cleaningagent vessel 126. - FIGS. 3B and 3D shows mop
container 106 and in that the collectingbowl 124 arranged in a “state of rest” (A). In themop container 106 is arranged amovable press plate 116, which is fixed to aportion 133 via thelinkarm system 122 to the foot pedal 134 (which is evident from FIG. 3A). The collectingbowl 124 is jointed and rotatably arranged in ashaft journal 166, here in the shape of a through bolt, via themop container 106. The apparatus further comprises aspring 168 which is arranged pre-stressed to push against therear wall 141 of the collectingbowl 124 and themop container backside 138, respectively, and thereby keep the collecting bowl horizontally pre-stressed in the state of rest (A) such that liquid can be stored therein. When thefoot pedal 134 is influenced invertical direction 170 which is evident from FIG. 3A, thepress plate 116 is pushed in direction against thesidewall 138 in themop container 106 and slides against the collectingbowl 124. As evident from FIG. 3C, the collectingbowl 124 rotates around theshaft journal 166 and is simultaneously pushed out through an opening in thesidewall 138 and angled/tipped down such that the liquid content is emptied. The collecting bowl is then in a “state of emptying” (B). - FIG. 3D shows also with broken lines, according to an embodiment of the present invention, an alternative member for emptying of liquid in the collecting bowl instead for the mechanism mentioned above, for angling/tipping of the collecting bowl. The collecting
bowl 124 can in that case in its bottom comprise one orseveral outlet valves 172, which can be controlled for opening/closing by the person skilled in the art in known manner. - Yet an alternative embodiment of the cleaning carriage is shown in FIG. 4A where the collecting
bowl 200 is in a “state of rest” where cleaning agent can be poured in the collecting bowl. In FIGS. 4A-B is the collectingbowl 200 arranged below themop container 202, at its opened lower part, and is arranged positioned against outside the mop containerslower edges 204, i.e. with the collecting bowls side edges arranged against/on at the outside of thelower edges 204 of the mop container, whereby it is guaranteed that cleaning agent can not flow outside on the outer surface of the collecting bowl. The collectingbowl 200 is rotatably arranged to the mop container at a joint 206, here shown as a hinge. The collecting bowl is furthermore fixed 208 to alinkarm system 210 to perform a movement, which in turn is arranged to afoot pedal 212. When thefoot pedal 212 is influence invertical direction 214, which is evident from FIG. 4A, thelinkarm system 210 is influenced which in turn influences down-tipping/angling of the collectingbowl 200. The collectingbowl 200 rotates around the joint 206, which is evident from FIG. 4B, and slants/tips down such that the liquid content is emptied. The collecting bowl is now in a “state of emptying”. In this embodiment, the collectingbowl 200 is only influenced by the foot pedal. The press plate/plates 216 in themop container 202 can be separately arranged to a handle or a foot pedal, or be arranged to be influenced when the collecting bowl is brought to rotate via thelinkarm system 210.
