Description

LAUNDRY TREATING MACHINE EQUIPPED WITH A HOLDING SYSTEM FOR A DRAINING LINE

The present invention concerns the field of laundry treating techniques.

In particular, the present invention refers to a laundry treating machine, preferably a laundry washing machine, equipped with a holding system for a draining line.

BACKGROUND ART

Conventionally, laundry treating machines comprise an external casing, or cabinet, within which a laundry treatment chamber is located. An opening gives access to the treatment chamber to load or unload the laundry before and after the treating cycle.

Known laundry treating machines comprise laundry washing machines, or combined laundry washing/drying machines, provided with a washing tub which contains a rotatable perforated drum, or treatment chamber, where the laundry is placed in order to be washed with water and proper treating agents (i.e. detergent, softener, rinse conditioner, etc.).

Water for washing the laundry is directly conveyed into the tub by means of a water supply unit or by making the water flowing through a dispenser containing the treating agents.

Laundry washing machines are then provided with a draining device for draining liquid, produced by the washing process, outside the cabinet to a drainage point arranged outside the machine and which is generally located nearby the place where the machine will be installed. The draining device is preferably constituted of a draining pump and a draining hose connected to a draining outlet of the draining pump. The draining hose is preferably realized as a single hose that has an inner portion extending inside the cabinet and an outer portion protruding outside the cabinet. The draining hose is connected to the pump outlet during manufacturing/assembling process of the machine and passed through a hole in the cabinet to protrude from it. The outer portion of the hose extending outside the cabinet is then available for the installation and connection to the drainage point.

Other known laundry treating machines comprise laundry drying machines provided with a drying tub, or treatment chamber, where the laundry is placed to be dried.

Laundry drying machines are then provided with a draining device for draining liquid, i.e. condensed water produced by the drying process, outside the cabinet to a drainage point arranged outside the machine.

Analogously to laundry washing machines also know laundry drying machines have a draining device constituted of a draining pump and a draining hose connected to a draining outlet of the draining pump. Here again, the draining hose is preferably realized as a single hose that has an inner portion extending inside the cabinet and an outer portion protruding outside the cabinet. The draining hose is connected to the pump outlet during manufacturing/assembling process of the machine and passed through a hole in the cabinet to protrude from it. The outer portion extending outside the cabinet of the hose is then available for the installation and connection to the drainage point where the machine will be installed.

However, the laundry treating machines equipped with a draining device of the known art pose some drawbacks.

A first drawback posed by the known draining device is constituted by the complexity of the maintenance operations in case of failure which may affect the draining hose. For example, the substitution of a broken draining hose requires the access to the inner side of the machine, typically by dismounting a side wall of the cabinet, disconnecting the hose from the pump outlet and removing the draining hose through the hole in the side wall from where it protrudes. Installation of the new draining hose will require then the operations of connecting the hose to the pump outlet and its re-insertion through the hole in the side wall of the cabinet.

Another drawback posed by the known draining device is constituted by the complexity of mounting operation during manufacturing steps. Assembling of the draining device requires to keep the draining hose in position in order not to interfere with the assembling of other components inside the cabinet.

The object of the present invention is therefore to overcome the drawbacks posed by the known techniques.

It is an object of the invention to provide a laundry treating machine equipped with a draining device which simplifies the maintenance compared to laundry treating machines of known type.
