Definitions

• 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.
• a cleaning carriage equipped with wheels
• 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.
• a cleaning carriage 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.
• 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.
• said means for emptying of liquid in the collecting bowl 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 claim 1, 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 claim 1, at a cleaning carriage for rinsing, cleaning and wringing out a mop.

• a collecting bowl 24 arranged in which a sufficiently amount of cleaning agent (such as pure water, cleaning agent, chemicals mixed with water, etc.) can be poured in for soaking, rinsing and cleaning the mop.
• the collecting bowl 24 is formed by connecting and closed interfaces such that a certain amount of cleaning agent temporarily can be retained in the collecting bowl for rinsing and cleaning of the mop.
• Cleaning agent is added via a separate vessel 26 via a valve 28 and a line 30 to the collecting bowl 24.
• the collecting bowl 24 is rotatably arranged around an axis of rotation 32 at the mop container 6.
• a foot pedal 34 can be arranged in connection to the handle 20 by influence of a second linkarm system 36.
• the movable perforated wall 16 When wringing out the mop, the movable perforated wall 16 is influenced, via the handle 20 or the foot pedal 34, in a direction against an opposite side wall 38 in the mop container 6. Simultaneously the collecting bowl 24, which is jointed 32 to the movable perforated wall 16, is pushed through an opening in the side wall 38 whereby the collecting bowl 24 is angled/tipped down such that contaminated cleaning agent in the collecting bowl is emptied in a bucket 40 for wastewater placed under the mop container.
