Abstract

A laundry machine ( 100 ) adapted to dry laundry by means of a flow of drying air has a machine cabinet ( 110 ) for accommodating components necessary for the operation of the laundry machine ( 100 ). Inside the cabinet is a laundry treatment chamber ( 105 ) adapted to contain the laundry to be dried. A cabinet top element ( 125 ) incorporated at least part of a drying air circuit in fluid communication with the laundry treating chamber through a drying air inlet opening ( 210 ) and through a drying air outlet opening ( 215 ) formed in the cabinet top element The cabinet top element has a bottom base element ( 205 ) and a top cover ( 240 ) and, defined in an interspace between the base element and the top cover, a drying air path for the flow of drying air between said drying air inlet opening ( 210 ) and said drying air outlet opening ( 215 ). The drying air path includes a moisture condensing arrangement ( 225, 230 ). The drying air inlet opening ( 210 ) is formed in a wall ( 217 a ) extending within the interspace between the base element ( 205 ) of the top element ( 125 ) and the top cover ( 240 ) thereof.

First claim

The invention claimed is:

1. A laundry machine configured to dry laundry by means of a flow of drying air, comprising:
a machine cabinet for accommodating components necessary for the operation of the laundry machine;
inside the cabinet, a laundry treatment chamber configured to contain the laundry to be dried;
a cabinet top element incorporating at least part of a drying air circuit in fluid communication with the laundry treating chamber through a drying air inlet opening and through a drying air outlet opening formed in the cabinet top element, the cabinet top element comprising a bottom base element and a top cover and, defined in an interspace between the base element and the top cover, a drying air path for the flow of drying air between said drying air inlet opening and said drying air outlet opening, said drying air path including a moisture condensing arrangement,
wherein the drying air inlet opening is formed in a wall extending within the interspace between the base element of the top element and the top cover thereof.

2. The laundry machine of claim 1 , wherein the base element comprises an aperture adjacent to the drying air inlet opening.

3. The laundry machine of claim 1 , comprising a return drying air hose coupled at one end thereof to the drying air inlet opening and, at another end, to a drying air outlet of the laundry treatment chamber.

4. The laundry machine of claim 3 , wherein the drying air inlet opening is surrounded by a projecting collar arranged in said interspace between the base element and the top cover and the return drying air hose is coupled to the collar.

5. The laundry machine of claim 1 , wherein the wall extends substantially perpendicularly to the base element.

6. The laundry machine of claim 1 , wherein the wall is formed integrally with the base element.

7. The laundry machine of claim 4 , wherein the end of the return drying air hose coupled to the drying air inlet opening is secured to the projecting collar by means of a first hose clamp.

8. The laundry machine of claim 7 , wherein the end of the return drying air hose coupled to the drying air outlet of the laundry treatment chamber is secured thereto by means of a second hose clamp.

9. The laundry machine of claim 8 , wherein the return drying air hose is provided, proximate to the end of the return drying air hose coupled to the drying air inlet opening, with an annular seat for accommodating the first hose clamp.

10. The laundry machine of claim 9 , wherein the return drying air hose is provided, proximate to the end of the return drying air hose coupled to the drying air outlet of the laundry treatment chamber, with a further annular seat for accommodating the second hose clamp.

11. The laundry machine of claim 1 , wherein said moisture condensing arrangement comprises heat-exchanging units part of a heat pump arranged for exchange of heat between the drying air and a heat pump refrigerant fluid, the heat pump further comprising a refrigerant fluid compressor installed inside the laundry machine cabinet at a bottom part of the laundry machine.

12. The laundry machine of claim 11 , wherein the refrigerant fluid compressor is in fluid communication with said heat-exchanging units in the top through flexible refrigerant fluid conduits, preferably running along a vertical corner of the machine cabinet.

13. The laundry machine of claim 11 , further comprising a refrigerant fluid compressor cooling fan arranged inside the machine cabinet at the bottom of the laundry machine, preferably attached to the laundry machine basement.

14. The laundry machine of claim 7 , wherein the return drying air hose is provided, proximate to the end of the return drying air hose coupled to the drying air inlet opening, with an annular seat for accommodating the first hose clamp.

15. The laundry machine of claim 11 , wherein the refrigerant fluid compressor is attached to a laundry machine basement.

16. The laundry machine of claim 12 , wherein the flexible refrigerant fluid conduits run along a vertical corner of the machine cabinet.

17. The laundry machine of claim 13 , wherein the refrigerant fluid compressor cooling fan is attached to the laundry machine basement.
