Description

The present invention relates to a household laundry washing and drying machine.
As is known, today's front-loading laundry washing and drying machines generally comprise: a substantially parallelepiped-shaped outer boxlike casing, typically structured for resting on the floor; a substantially bell-shaped washing tub which is generally suspended in floating manner inside the casing via a number of coil springs and shock-absorbers, with the front opening/mouth directly facing a laundry loading/unloading pass-through opening provided in the front wall of the casing; a substantially cylindrical elastically-deformable bellows which connects in watertight manner the front mouth/opening of the bell-shaped washing tub to the laundry loading/unloading opening on front wall of the casing; and a porthole door which is hinged to the front wall of the casing to rotate to and from a closing position in which the door rests on the front face of the casing to close the laundry loading/unloading on the front wall and substantially watertight seal the washing tub.
The front-loading laundry washing and drying machines of the above type furthermore comprise: a substantially bell-shaped, cylindrical revolving drum which is structured for housing the laundry to be washed and/or dried, and is housed in axially rotating manner inside the washing tub for rotating about its longitudinal reference axis; an electric motor assembly which is located outside of the washing tub, and is structured for driving into rotation the revolving drum about its longitudinal reference axis inside the washing tub; and a, preferably closed-circuit, air duct assembly which is structured to circulate inside the washing tub a stream of hot air having a low moisture content, and which flows through the revolving drum and over the laundry inside the drum to dry the laundry.
The air duct assembly is structured for gradually drawing air from the washing tub; cooling down the air arriving from the washing tub so to extract and retain the surplus moisture in the air; heating the dehumidified air to a predetermined temperature, normally higher than the temperature of the air arriving from the washing tub; and feeding the heated, dehumidified air back into the washing tub, where it flows over the laundry stored inside the revolving drum to dry the laundry.
In several models of known front-loading laundry washing and drying machines, the cooling down and dehumidification of the air drawn from the washing tub is performed inside cold-air duct, e.g. a cold-water condenser which is attached/ integrated to/on the back of the washing tub, obviously inside the boxlike casing, and which uses the cold tap water of the water mains as refrigerant.
In some known front-loading laundry washing and drying machines the heating up of the dehumidified air coming out of the cold-water condenser is performed inside an air heating device which is rigidly attached to the top of the washing tub so as to have a first end in direct communication with the cold-water condenser and a second end in direct communication with the washing tub close to the front mouth of the latter, and which internally houses the electric centrifugal fan that circulates the air across the washing tub and the resistor that heats up the dehumidified air directed back into the washing tub.
W02010/100114 discloses an air duct assembly of the type referred above; in particular W02010/100114 discloses a laundry drying machine comprising a drying passage (i.e. an air heating device) including a base and a cover joined to the base. Each edge of the base and the cover is provided with a receiving groove of a certain depth. A sealing strip, made of an elastic material, for sealing the junction of the base and the cover is received within the receiving grooves. A plurality of notches is disposed inside the receiving groove, and a plurality of bosses is correspondingly disposed on the periphery of the sealing strip. During assembly, each boss of the sealing strip is received into a corresponding notch of the groove.
However the solution disclosed in W02010/100114 seems not so effective in preventing an incorrect positioning of the sealing strip with respect to the drying passage, and moreover the assembly of the sealing strip to the drying passage seems to be not so ergonomic and functional.
Aim of the present invention is to provide an alternative solution to obtain a more effective and ergonomic way for ensuring the correct positioning of a sealing gasket with respect to the air heating device of a laundry washing and drying machine.
Another object of the present inventions is simplifying and speeding up the assembly of the washing and drying machine.
Applicant has found that by providing at least one of two or more hemi-shells composing the tubular body of the air heating device of a laundry washing and drying machine with one or more protruding elements adapted to mate with one or more corresponding seats provided in a portion of an intermediate sealing gasket interposed between the hemi-shells to seal them one another, it is possible to obtain an easy, effective, and ergonomic reciprocal positioning of the hemi-shell and the intermediate sealing gasket. This allows reducing the complexity of the assembly of the air heating device, and therefore the time and the costs required for such an assembly, which has a positive effect on the overall costs of the laundry machine.
In particular, the above-mentioned aim and objects, as well as others that will become better apparent hereinafter, are achieved by a laundry washing and drying machine comprising: an outer casing; a hollow washing tub housed inside the casing; a air heating device attached onto the washing tub and comprising a tubular body, structured for being crossed by an airflow, and an air-heating device. The tubular body comprises at least two hemi-shells reciprocally coupled to compose/form the tubular body, and an intermediate sealing gasket interposed between the at least two hemi-shells to seal the hemi-shells one another. At least one of the two or more hemi-shells comprises one or more protruding elements adapted to mate with one or more corresponding seats provided in a portion of the intermediate sealing gasket, so as to set the reciprocal position of the at least one of the two or more hemi-shells and the intermediate sealing gasket.
In an advantageous embodiment the intermediate sealing gasket comprises a main body arranged in such a way to be interposed between the two or more hemi-shells when the two or more hemi-shells are coupled one another.
Preferably, the intermediate sealing gasket comprises one or more lugs or wings protruding from the main body and provided with at least one of the one or more of seats for receiving the one or more protruding elements.
More preferably, a plurality of lugs or wings is spaced along the main body.
Advantageously, at least one of the one or more lugs or wings protrudes, in the assembled condition of the tubular body, externally from the tubular body, in such a way to locally protect the tubular body from the bumps.
In a further advantageous embodiment, one or more of the seats for receiving the protruding elements are provided directly on the main body.
Preferably, a plurality of seats is spaced along the main body.
In an advantageous embodiment, the protruding element comprises one or more pins protruding from one of the two or more hemi-shells, the one or more pins being positioned in such a way to be housed into a corresponding seat of the intermediate sealing gasket.
Advantageously, the one of the two or more hemi-shells comprising the one or more protruding elements comprises one or more protrusion, comprising the one or more protruding elements, and arranged in such a way to be positioned in correspondence of the one or more seats of the intermediate gasket.
In an advantageous embodiment, the intermediate sealing gasket is made of an elastomeric material.
Preferably, the hemi shell comprising the one or more protruding elements is provided with one or more ribs protruding from its peripheral edge and adapted to provide a guide/support for the positioning of the intermediate sealing gasket.
In a further advantageous embodiment, the peripheral edge of at least one of the hemi-shells is provided with a longitudinal grove or seat, and the main body of the sealing gasket is shaped/dimensioned so as to be at least partly recessed into the longitudinal grove or seat.
In an advantageous embodiment, the main body of the intermediate sealing gasket is substantially annular in shape.
In a further advantageous embodiment the main body of the intermediate sealing gasket is open in shape.
A non-limiting embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:

Centrifugal fan 14, is preferably recessed on a portion of tubular body 12 suitably shaped to form the outer volute or impeller housing of centrifugal fan 14.
Preferably, though not necessarily, the air heating device 7 furthermore comprises one or more temperature sensors 17 which are located inside, or faced to the inside of, tubular body 12 and are structured for measuring the temperature of the air flowing inside tubular body 12, preferably close to the second opening or mouth 12b of the tubular body 12.
With reference to Figures 2 and 3, tubular body 12 comprises at least two complementary hemi- shells 21 and 22 having their peripheral edges 21a and 22a structured for being reciprocally coupled to compose/form the tubular body 12, and an intermediate sealing gasket 23 which is structured for being interposed between the hemi-shells 21 and 22 (preferably between the peripheral edges 21a and 22a of the latter) to seal in substantially airtight manner the hemi- shells 21 and 22 one another.

Preferably, but not necessarily, the hemi-shells comprising the protruding elements 30 (for example the hemi shell one numbering 21 in enclosed Figures) comprises one or more protrusion 33 comprising, on their turn, one or more protruding elements 30; advantageously protrusions 33 are arranged in such a way to be positioned in correspondence of the one or more seats 31 of the intermediate gasket 23, preferably in correspondence of the lugs or wings 32, so that the latter may be positioned on the protrusions 33.
Preferably, the hemi shell 21 comprising the protruding elements 30 is provided with one or more ribs 34 (e.g. a single continuous perimeter rib, like in the example of Figure 3, or a plurality of ribs, separated one another) protruding from the peripheral edge 21a of the hemi shell 21 and adapted to provide a guide or support for the positioning of the body 23a of the intermediate sealing gasket 23. In this case, during the assembly of the tubular body 12, the intermediate sealing gasket 23 may be positioned on the hemi shell 21 in such a way that its body 23a lays against the one or more ribs 34, while the positioning of the protruding elements 30 into the corresponding seats 31 ensures the correct reciprocal positioning.

The tubular body 12 is preferably composed by a substantially basin-shaped, lower hemi-shell 21 which is structured for being rigidly fixed to the top of the washing tub 3 preferably via a number of anchoring screws 18, and by a substantially lid-shaped, upper hemi-shell 22 which is shaped/dimensioned to rest in abutment on the annular upper rim 21a of hemi-shell 21 to completely close the basin-shaped lower hemi-shell 21.
The basin-shaped lower hemi-shell 21 is furthermore preferably provided with two coupling collars/manifolds which protrude downwards from the bottom of the hemi-shell 21 and are shaped/dimensioned to fit/couple in substantially airtight manner respectively with the air escape mouth of the air cooling device 6 and with an auxiliary pass-through opening provided either on the cylindrical bellows, not illustrated, connecting washing tub 3 to the laundry loading/unloading opening on front wall 2a, or directly on the body of washing tub 3.
Preferably the substantially basin-shaped, lower hemi-shell 21 is furthermore shaped/dimensioned so to directly house the resistor 13.
The substantially lid-shaped, upper hemi-shell 22, is preferably, though not necessarily, structured/shaped to directly support the temperature sensors 17 preferably aligned immediately above the coupling collar/manifold that connects the hemi-shell 21 directly or indirectly to the inside of washing tub 3.
A first half of the outer volute of centrifugal fan 14 is furthermore preferably, though not necessarily, provided directly on the substantially basin-shaped, lower hemi-shell 21 locally substantially coaxial to the coupling collar/manifold structured to be fitted/coupled to the air escape mouth of the air cooling device 6, whereas a second complementary half of the outer volute of centrifugal fan 14 is provided on the lid-shaped upper hemi-shell 22, so that the complete outer volute of centrifugal fan 14 is composed when the upper and lower hemi- shells 21 and 22 are coupled to one another.
In the example shown, both upper and lower hemi- shells 21 and 22 are preferably made of a metal (preferably aluminum).
In the examples shown, the intermediate sealing gasket 23 is preferably made of an elastomeric plastic material and is made in one piece via an injection molding process.
General operation of the front-loading laundry washing and drying machine 1 is clearly inferable from the above description, with no further explanation required.
During the assembly if the air heating device 7, the operator can easily correctly positioning the intermediate sealing gasket 23 to the hemi shell 21 by placing the protruding elements 30 into the seats 31; this process is particularly easy and ergonomic and allows reducing the assembly time, and therefore the overall costs of the machine.
Moreover, the mating of the protruding elements 30 with the seats 31 reduces the risk that once associated to the hemi shell 21, the intermediate sealing gasket 23 could accidentally be misplaced, for example due to the movement of the partially assembled entity hemi shell 21/intermediate sealing gasket 23.
Moreover the fact that some of the lugs or wings provided with the seats protrudes externally from the tubular body 12, in such a way to locally protect the tubular body 12 from the bumps effectively protects the air heating device from the bumps due for example to the shaking of the tub to which the air-duct assembly is attached, without increasing the complexity and the production costs of the machine.
Clearly, changes may be made to either the laundry washing and drying machine as described herein without, however, departing from the scope of the present invention.
