摘要:
A home laundry drier (1) comprising an outer box casing (2) and, inside the casing, a laundry drying drum (3) for housing the laundry to be dried, and a hot-air generator (7) for circulating a stream of hot air inside the drying drum (3); the hot-air generator (7) comprising an air recirculating conduit (8) connected at both ends to the laundry drying drum (3), and a heat-pump assembly (10) which is able to rapidly cool the airflow (f) coming out from the drying drum (3) for condensing the surplus moisture in said airflow (f), and then to rapidly heat the airflow (f) returning back into the drying drum (3); the heat-pump assembly (10) using the carbon dioxide as refrigerant, and being designed to maintain the whole refrigerant in a gaseous state in all the thermodynamic transformations making up the closed thermodynamic cycle performed by the heat-pump assembly (10).
摘要:
The present invention relates to a refrigerator for cooling beverage bottles, such as a wine cooler, which refrigerator is mountable at a wall. The refrigerator comprises a cabinet, which has the shape of a slab with a generally planar extension; a cool compartment, which is arranged inside the cabinet; a refrigerating unit, which is arranged to cool the cool compartment; and a single support structure for supporting several bottles, which support structure is arranged in the cool compartment. The support structure is designed to support several bottles such that the bottles are oriented in a single, common storage layer, wherein the storage layer is substantially parallel with the planar extension of the cabinet, whereby the cabinet and the storage layer, when the refrigerator is mounted along a straight wall, are at least substantially in parallel with the wall. The present invention also relates to a user interface for such a refrigerator.
