Abstract

A top adapted to match and close from above a cabinet of a laundry drying appliance is provided. The top is formed as a ready-to-mount part ready to be mounted to the cabinet and forming a moisture condensing module for dehydrating drying air used to dry laundry within a drying drum of the laundry drying appliance. The top has a drying air inlet for receiving moisture-laden drying air, a drying air outlet for delivering demoisturized drying air, fluid passageways defined thereinside from the drying air inlet to the drying air outlet for the passage of the drying air to be dehydrated and a moisture condenser arranged inside the fluid passageways. The top includes, integrally formed therein, at least one structural part of the appliance, the at least one structural part of the appliance having at least one of: a part a housing of a fan for propelling the drying air; a drying air delivery duct connectable to a drying air inlet of the drying drum for delivering the drying air into the drying drum; a seat for a container of detergents/softener for washing laundry; a condense water collector for collecting condense water released by the moisture-laden drying air; at least part of a condense water draining system; a support for at least one water inlet valve for selectively allowing the intake of water from a water main; and at least part of a water circuit for delivering water to wash the moisture condensing means.

First claim

The invention claimed is:

1. A top adapted to match and close from above a cabinet of a laundry drying appliance, the top being formed as a ready-to-mount part ready to be mounted to the cabinet and forming a moisture condensing module for dehydrating drying air used to dry laundry within a drying drum of the laundry drying appliance, the top having a top surface, a bottom surface, and a lateral wall and comprising:
a drying air inlet for receiving moisture-laden drying air, a drying air outlet for delivering dehydrated drying air, wherein the drying air inlet and the drying air outlet are either provided on the bottom surface or on the lateral wall,
fluid passageways defined thereinside from said drying air inlet to said drying air outlet for the passage of the drying air to be dehydrated, and
a moisture condenser arranged inside said fluid passageways,
wherein:
the moisture condenser is an air-air heat exchanger or a heat exchanger of a heat pump circuit, and
the top further comprises, integrally formed therein, at least one structural part of the appliance, said at least one structural part of the appliance comprising at least one of the following:
a part of a housing of a fan operable for propelling the drying air;
a drying air delivery duct connectable to a drying air inlet of the drying drum for delivering the drying air into the drying drum;
a seat for a container of detergents/softener for washing laundry;
a condense water collector for collecting condense water released by the moisture-laden drying air;
at least part of a condense water draining system;
a support for at least one water inlet valve for selectively allowing the intake of water from a water main; and
at least part of a water circuit for delivering water to clean the moisture condensing means.

2. The top of claim 1 , comprising the part of a housing of a fan, wherein said part of fan housing that is formed integrally to the top defines a first half-shell of the fan housing, to which a part defining a second half-shell is couplable for defining a shell accommodating therein a fan wheel.

3. The top of claim 2 , comprising the drying air delivery duct wherein said drying air delivery duct is formed integrally to one of: the part of fan housing that is formed integrally to the top; and the part defining the second half-shell.

4. The top of claim 1 , comprising the at least part of a condense water draining system, the condense water collector, and the seat for the detergents/softener container, wherein the condense water draining system comprises a conduit fluidly connecting the condense water collector to the seat for the detergents/softener container.

5. The top of claim 4 , wherein the top further comprises a water delivery assembly comprising a water deliverer for delivering water into the seat for the detergents/softener container.

6. The top of claim 4 , wherein the detergents/softener container is a drawer slidably accommodated within the seat and having one or more detergents/softener compartments.

7. The top of claim 1 , comprising the at least part of the water circuit for delivering water to clean the moisture condensing means, the at least part of the water circuit comprises at least one nozzle for sprinkling water onto the moisture condenser, said nozzle being fed with water coming either from said water main or from said condense water collecting means.

8. The top of claim 7 , wherein said at least part of the water circuit for delivering water to clean the moisture condenser is connected or connectable to a pump for pumping the water from the condense water collector to said nozzle.

9. The top of claim 7 , wherein said at least part of the water circuit for delivering water to clean the moisture condenser comprises at least one pump for pumping the water from the condense water collector to said nozzle.

10. The top of claim 7 , wherein said at least part of the water circuit for delivering water to clean the moisture condenser is connected or connectable to at least one valve for selectively feeding water from the water main to said nozzle.

11. The top of claim 7 , wherein said at least part of the water circuit for delivering water to clean the moisture condenser comprises at least one valve for selectively feeding water from the water main to said nozzle.

12. The top of claim 1 , wherein said moisture condenser comprises said heat exchanger of a heat pump circuit, said heat exchanger being operable for cooling and dehydrating the moisture-laden drying air.

13. A laundry drying appliance, comprising a cabinet having a top, a rotatable drying drum accommodated within the cabinet, and a laundry drying air circulation system for circulating drying air, wherein the top is in accordance to claim 1 and wherein the drying air circulation system comprises a drying air drum outlet connectable to the drying air inlet of the top, and a drying air drum inlet connectable to the drying air outlet of the top.

14. The top of claim 2 , wherein said at least part of a condense water draining system comprises a conduit fluidly connecting the condense water collector to the seat for the detergents/softener container.

15. The top of claim 3 , wherein said at least part of a condense water draining system comprises a conduit fluidly connecting the condense water collector to the seat for the detergents/softener container.
