Definitions
- the present invention relates to an electric household appliance and relative operating method.
- the present invention relates to a washer-drier machine employing a wash fluid comprising a silicone solvent and/or water, or to a tumble laundry drier; to which the following description refers purely by way of example.
- known home tumble laundry driers comprise: a substantially parallelepiped-shaped casing; a laundry drying drum mounted inside the casing to rotate about an axis of rotation, and facing a laundry loading-unloading opening formed in the front wall of the casing; a door hinged to the front wall of the casing to rotate to and from a work position closing the opening in the front wall; and a drive assembly for rotating the laundry drying drum about its axis of rotation.
- Driers of the above type also comprise a hot-air generator for generating and circulating inside the drying drum a stream of hot, low-moisture air which flows through the drying drum to rapidly dry the laundry inside.
- the hot-air generator operates in the same way as a heat pump, circulates the same air inside the drying drum, and continually extracts the surplus moisture from the hot air issuing from the drying drum after flowing through the laundry inside the drum.
- the hot-air generator comprises a refrigerant compression device or so-called compressor, which transfers heat from one fluid to another by means of an intermediate refrigerant subjected to a closed thermodynamic cycle, so as to rapidly cool and so reduce the moisture content of the air issuing from the drying drum.
- the compressor comprises a reciprocating or rotary mechanical compressor assembly to compress the intermediate gaseous refrigerant; and an electric motor, the output shaft of which is connected to the mechanical compression member to rotate or produce reciprocating movement of the compression members.
- the electric motor is designed to rotate its output shaft at constant speed, and to rotate or produce a reciprocating movement of the compression members to obtain a substantially constant average flow of compressed refrigerant, and is controlled by the electronic central control unit via an on/off control system, which turns the electric motor on/off, depending on the balance condition of the intermediate refrigerant thermodynamic cycle.
- the blade rotation speed or linear piston speed of the compression members of the compressor can only assume two values: maximum, when the heat pump is working; or zero, when the heat pump is off.
- Document EP-A1-1811077 discloses a drying machine including a refrigerant circuit comprising a compressor, a fan and a control unit for adjusting the air flow rate of said fan and for lowering the number of the rotations of the compressor when the discharged refrigerant temperature of said compressor raises.

- a hot-air generator 7 housed inside casing 2 and designed to circulate inside drying drum 3 a stream of hot, low-moisture air, which flows over, to rapidly dry, the laundry inside the drum.
- hot-air generator 7 operates in the same way as a heat pump, by transferring heat from one fluid to another by means of an intermediate refrigerant subjected to a closed thermodynamic cycle, the thermodynamic principles of which are commonly known and therefore not described in detail, and provides for gradually drawing air from drying drum 3; extracting surplus moisture from the hot air drawn from drying drum 3; heating the dried air to a predetermined temperature, normally higher than that of the air inside drying drum 3; and feeding the heated, dried air back into drying drum 3, where it again flows over, to rapidly dry, the laundry inside the drum.
- hot-air generator 7 continually dries and heats the air drawn from drying drum 3, to rapidly dry the laundry inside the drum.
- hot-air generator 7 substantially comprises an air-circulating pipe 8 connected at one end to a perforated rear wall of drying drum 3 to feed hot air into drum 3, and at the other end to a front portion of drying drum 3, from which it draws moisture-laden air out of the drum.

- an electronic central control unit 15 which regulates the speed of motor 9b of compression device 9 by means of a signal CV, and turns electric motor 14b of ventilation device 14 on/off by means of a signal CR, so as to rotate fan 14a, or not, depending on the temperature T of the refrigerant circulating in refrigerant circuit 12.
- Drier 1 also comprises at least one temperature sensor 16, e.g. a thermocouple, located along refrigerant circuit 12 to transmit to electronic central control unit 15 the temperature T of the refrigerant circulating in refrigerant circuit 12. More specifically, in the Figure 1 example, temperature sensor 16 is located along second portion 12b of refrigerant circuit 12 to measure the temperature T of the refrigerant issuing from second heat exchanger 11.
- temperature sensor 16 e.g. a thermocouple
- Drier 1 also comprises an interface device 18 enabling the user to select an energy-saving drying cycle, which substantially provides for reducing, for a given time period, the rotation speed, with respect to a steady-operating rotation speed, of electric motor 9b of compression device 9, and for simultaneously activating/deactivating rotation of fan 14a to keep refrigerant temperature T around a predetermined target temperature T o .
- the energy-saving drying cycle comprises the following steps. To begin with, ventilation device 14 is kept off, and electronic central control unit 15 brings electric motor 9b of compression device 9 up to its maximum steady speed V MAX (interval A in Figure 2 ).
- the maximum steady speed V MAX of electric motor 9b may be, for example, about 6000 rpm; and, at this step, the refrigerant temperature T measured along portion 12a of refrigerant circuit 12 increases rapidly (interval A in Figure 2 ).
