## Abstract

A household appliance (100) comprises a cabinet (105) accommodating a drum for loading items to be dried and a drying air circuit for circulating drying air through the drum for drying the items therein. The drying air circuit comprises air heating elements (415) for heating the drying air fed to the drum, and the cabinet is provided with a worktop (110) defining a surface (130) having a plurality of apertures (135) in fluid communication with an air conveying system (205,225,230) adapted to deliver a flow of air through said apertures. The air conveying system comprises an air duct (230) thermally coupled to the air heating elements in such a way as to cause heat generated by the air heating elements to heat the air to be delivered through the apertures in the drying surface.

## Claims

### Claim 1

A household appliance comprising a cabinet accommodating a drum for loading items to be dried and a drying air circuit for circulating drying air through the drum for drying the items therein, said drying air circuit comprising air heating elements for heating the drying air fed to the drum, and wherein the cabinet is provided with a worktop defining a surface having a plurality of apertures in fluid communication with an air conveying system adapted to deliver a flow of air through said apertures,
wherein said air conveying system comprises an air duct having a wall which separates the flow of air in the drying air circuit from the flow of air in said air conveying system and prevents the latter from passing through the air heating elements, the air duct of said air conveying system being thermally coupled to said air heating elements through said wall in such a way as to cause heat generated by the air heating elements to heat the air flowing in the air duct to be delivered through said apertures in the drying surface.

### Claim 2 (depends on 1)

A household appliance of claim 1, wherein said drying air circuit comprises an air-cooled condenser for cooling the drying air exiting the drum and removing moisture therefrom, and wherein the air duct is arranged to collect the condenser cooling air after it has cooled the condenser.

### Claim 3 (depends on 1)

The household appliance of claim 1, comprising an air circulation arrangement for causing air to flow through the air duct up to the drying surface.

### Claim 4 (depends on 3)

The household appliance of claim 3, wherein said air circulation arrangement comprises a blower provided in the cabinet for taking in from the outside ambient air for cooling the condenser.

### Claim 5 (depends on 3)

The household appliance of claim 3, wherein said air circulation arrangement comprises a blower provided in the air conveying system for taking in from the outside ambient air and forcing it to flow through the apertures of said surface.

### Claim 6 (depends on 1)

The household appliance of claim 1, wherein said air duct is arranged along a back wall of the cabinet.

### Claim 7 (depends on 1)

The household appliance of claim 1, wherein said air duct is arranged to be in close proximity to said air heating elements.

### Claim 8 (depends on 7)

The household appliance of claim 7, wherein said wall separating said air duct from said heating elements comprises a thermally conductive metal material.
