Definitions
- the present invention refers to a household clothes washing and drying machine, generally known as a washer-dryer in the art, in which the clothes are loaded into a substantially horizontal-axis rotating drum from the top thereof.
- the internal architecture of a washer-dryer is inherently more complex than the one of a simple clothes washing machine.
- the means that are intended to ensure the inlet, the recirculation and the outlet of the washing liquor to, in and from the oscillating tub enclosing the rotating drum there must in fact be provided, and appropriately arranged, the means that are needed to create a flow of air in a closed-loop circuit during the clothes drying phases.
- top-loading clothes washing and drying machines are rather unfrequent, owing also to the difficulty that is found, from an industrial engineering and manufacturing point of view, in making such a complex machine with an outer casing that must be ensured rather small dimensions, particularly as far as its width is concerned, and an adequate capacity in terms of amount of clothes loadable therein for treatment. Even the specific patent literature dealing with such machine models appears to be quite scarce.
- the closest state-of-the-art is in fact represented in this case by the document EP-A-0 427 610, which however refers to a so-called tumble dryer, that is a machine that is adapted to solely dry the clothes.
- the means provided to create a forced flow of the drying air are accommodated partly in the first one and partly in the second one of the two stationary disks that are fixed to the seats of the bearings of the rotating drum, which is provided on top with a lid for loading the clothes thereinto.
- the first disk which is relatively flat
- an electric heating element extending in a uniform manner over the whole surface thereof
- the second disk which is on the contrary convex, ie. domed towards the interior of the drum, there is accommodated the impeller of a motor-driven fan.
- the outer casing has a width in the order of 45 cm, which is therefore larger than the width (40 cm) of the most recent top-loading washing machine models.
- Most of the top face of the casing 1 is occupied by a clothes loading aperture 2, wherein a rectangular lid 3 is hinged on along the rear side adjacent to a control panel 4 carrying the various control and display or indicating devices 5 of the machine.
- Within the thickness of the lid 3 there are housed some compartments 6 intended for containing the chemical aids to be filled in for use in the washing phases of the operating cycles of the machine.
- the interior of the casing 1 accommodates an oscillating tub 9 which is essentially constituted by a cylindrical enclosure and two vertical head pieces on the front and the rear side thereof, wherein said tub houses a single perforated drum 7 provided with a double-shutter lid 8 for loading and removing the clothes through the aperture 2.
- the drum 7, therefore, is of the type rotating about a sensibly horizontal axis, parallel to the width dimension L of the casing 1, as driven by an electric motor mounted below the tub 9.
- this head piece which is generally indicated at 10, substantially consists of a first portion 11 and a second portion 12, preferably made of metal and separably joined to each other.
- the first such portion 11 which is flat in substantially the shape of a volute, is provided with a plurality of perforated tabs 13 along the whole periphery thereof, as well as a circular seat 14 that is perforated on the bottom to accommodate the pulley 16 of the impeller 15 of a fan, as this will be described in greater detail further on - see Figure 2.
- the second such portion 12 (which is preferably made by die-casting) is substantially in the shape of a pan with a disk-shaped bottom, an outer peripheral edge 17 and an inner peripheral edge 18, both of them provided in a raised form, between which the place is provided for arranging the seat 30 for at least one of the bearings (not shown) of the drum 7.
- the outer edge 17 comprises both a continuous groove 19 to accommodate a sealing material and a first set of bushes 20 for the screws (not shown) used to fix the head piece 10 to the cylindrical enclosure of the tub 9.
- the inner edge 18, which is higher than the outer edge 17, is provided with a second set of threaded bushes 21 for the engagement of bolts (not shown, either) that get inserted in the perforations in the tabs 13 - see Figure 2.
- the same second portion 12 of the head piece 10 is provided with a circular aperture 22 having a diameter that is just slightly smaller than the outer diameter of the impeller 15 which is mounted inside the same channel 28 in such a manner as to enable the pulley 16 to be fixed, on the outside of the head piece 10 of course, on to the shaft 15A thereof protruding through the perforation on the bottom of the recessed seat 14.
- a first aperture 23 having a rectangular shape and a second aperture 29 having a falcate shape At a second end portion of the channel 28 on the inner edge 18 there are provided a first aperture 23 having a rectangular shape and a second aperture 29 having a falcate shape.
- the rectangular aperture 23 (see Figure 2) is arranged to face the outer edge 17 and accommodates the flange 24 of a sheathed-type resistance heating element 25 for heating up the air intended for drying the clothes, wherein on said flange 24 there are furthermore attached in a conventional manner two temperature adjusting or temperature limiting devices 26 and 27.
- a surface-type steam condenser 31 is provided integrally in the second portion 12 of the head piece 10.
- the condenser 31 in view of maximizing the efficiency of the heat-exchange process between the water used as a cooling medium and the moisture removed in its vapour phase from the clothes by the drying air, the condenser 31 has a meandering shape.
- the water flowing in from the mains through an inlet 33 in the lowest point, is in this way able to follow a relatively long course before mixing up with the condensate liquid starting at a point 32 in a higher position on the edge 18.
- the water and the condensate liquid are conveyed, through an appropriate outlet (not shown), directly to the bottom of the tub 9.
- the same second portion 12 of the head piece 10 of the tub 9 comprises an appendix 34 that is roughly radial with respect to the axis of the seat 30 (which at the same time is the axis of rotation of the drum 7).
- an appendix 34 is particularly strong owing to the provision of structural reinforcing ribs and terminates with a circular aperture 35 adapted to accommodate a pulley 36 associated to the electric motor (not shown in the Figures, but situated below the cylindrical enclosure of the tub 9) that, through a belt (not shown, either), drives the pulley 16 of the impeller 15 of the fan.
- the perforated drum 7 enclosed in the tub 9 is kept rotating about the horizontal axis thereof by the afore mentioned driving motor.
- the clothes drying air is circulated in a closed-loop circuit that comprises, in a logic sequence, the sheathed heating element 25, the falcate aperture 29, the tub 9 and then the drum 7, where the so heated-up air collects, ie. takes on the moisture removed in its vapour phase from the clothes, the aperture 22 in the portion 12 of the head piece 10, the impeller 15 and, finally, the channel 28, following the direction shown by the arrows in Figure 3, until the flow of said drying air eventually reaches again the sheathed heating element 25.
- the moisture that is removed in its vapour phase from the clothes by the action of the drying air is reduced, ie. condensed and the mixture of condensate liquid and cooling water, which then so forms, falls directly onto the bottom of the tub 9, below the drum 7.
- a pump (not shown)
- such a mixture is duly let out of the washer-dryer, but can as well be stored in an appropriately provided reservoir (not shown, either) in view of a utilization thereof in a subsequent washing cycle performed by the machine.
