摘要:
A dryer of at least one product comprises: - a rotary drum (2); - a perforated shell (3) which may be fitted inside the drum (2) and defining an inner compartment (30) suitable for holding at least one product to be dried. The perforated shell (3) comprises an outer rolling surface (31) which during the rotation of the drum (2) is free to roll spontaneously along a first inner surface (32) of the drum (2) thereby rotating the perforated shell (3).
摘要:
The present invention relates to a method for detecting a submerged or emerged operating condition of an electric resistance used in a washing machine. In the first step of the method, the electric resistance is turned on for a first time interval. In the second step of the method, the electric resistance is turned off. In the third step of the method, the temperature detected by a temperature sensor in a condition of thermal exchange by conduction with the resistance is measured, so that water is supplied into the tub when the temperature reaches or exceeds a predetermined threshold value.

Household electrical appliance for drying items comprising: -a drying compartment (2) for the items; -a first channel (3) which envisages an inlet (31) of a fluid present in the drying compartment (2) and an outlet (32) for re-introducing said fluid into the drying compartment (2); -suction and movement means (30) of said fluid into the first channel (3); -a second channel (4) which envisages a cooling air inlet (41) from the outside of the household electrical appliance (1) and an air outlet (42) to the outside of the household electrical appliance (1); -suction and movement means (40) of said air into the second channel (4); -a heat exchanger (5) which puts into thermal communication at least one stretch of the first channel (3) and a stretch of the second channel (4) and in which the cooling air takes heat away from the fluid transiting in the first channel (3); -purification means (6) of the cooling air, said purification means (6) being electrically powered and being placed along the second channel (4) to treat the air intended to be returned to the outside of the household electrical appliance (1).
摘要:
A drying or washing/drying machine comprising means for generating steam for treating laundry items, means for drying laundry items, a tub for containing the laundry items, a door (2) for closing the tub, a reservoir (3,3') for a liquid to be vaporized, associated with the door, wherein the steam generating means are associated with the door (2), thus avoiding the use of flexible hydraulic connections between said steam generating means and the reservoir (3,3').
摘要:
A laundry-drier machine has a cabinet (2), housed within which is a rotary drum (3) for the laundry. The machine (1) has a control system (5, 6, 25, 26) pre-arranged for controlling execution of at least one operating program that comprises a drying step. The drying step includes at least one substep, during which the drum (3) is brought to assume a given speed of rotation, which is equal to or higher than the minimum speed that enables the garments to be kept adherent to the wall of the drum (3). The control system (5, 6, 25, 26) comprises sensor means (26) for detecting, in the course of the drying step, values of moisture of at least one of the load of laundry contained in the drum (3) and the air of the forced flow (F) leaving the drum (3). The control system (5, 6, 25, 26) is pre-arranged for starting said substep, at the given speed of rotation of the drum (3), when a value of moisture detected is equal to or lower than a first threshold moisture value.
