The present invention relates to washing machines and tumble dryers of the type used in commercial laundries for cleaning and drying batches of laundry.
In commercial laundries, batches of washing are typically delivered to the washing machines by means of an overhead rail laundry transfer system having a railed storage area in which the soiled articles to be washed are sorted into select batches. The batches of dirty laundry are typically loaded into respective containers, typically bags, suspended from the overhead rails and held in a storage area. The bags are then moved from the storage area and around the laundry to a washing machine and the dirty washing loaded into the washing drum of the machine.
The washing machines are generally front loaders and laundry may be discharged into a cart and then loaded into the machine manually. Alternatively, the suspended container may be manoeuvred so that it can be discharged directly into the door of the machine. This is not always successful and the operator may need to retrieve items from the floor and/or may need to manually distribute the dirty laundry in the machine. A similar problem exists with loading batches of washed laundry into a tumble dryer, which are also generally front loaders.
According to a first aspect of the present invention, there is provided a loading device attachable to the front of a front-loading laundry machine, said laundry machine comprising a drum, a drum port and a drum port door for selectively closing the drum port; said loading device comprising: a deformable chute mounted on a collapsible frame, and a pair of brackets for mounting said collapsible frame to said laundry machine such that said loading device is configurable between: a use condition in which said collapsible frame is open and the deformable chute is taut for directing laundry through said drum port into said laundry machine, and a storage condition in which said collapsible frame is closed for allowing the drum port door of said laundry machine to be closed.
In an embodiment, said collapsible frame comprises an inner part and an outer part pivotable relative to the inner part between: a raised position, in which the collapsible frame is open to hold said deformable chute taut, and a lowered position, in which the collapsible frame is closed. In an embodiment, the loading device comprises a locking means for holding the outer part in a raised position, to hold said deformable chute taut
According to a second aspect of the present invention, there is provided a front-loading laundry machine comprising a drum, a drum port and a drum port door for selectively closing the drum port, said front -loading laundry machine provided with the loading device of the first aspect located adjacent the drum port.
