  • 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.
  • an electric household appliance in particular a laundry drier, as claimed in Claim 1 and preferably, though not necessarily, in any one of the Claims depending directly or indirectly on Claim 1.
  • an electronic control device for installation in an electric household appliance, and as claimed in Claim 9.
  • Number 1 in Figure 1 indicates as a whole an electric household appliance, in particular a home laundry drier, substantially comprising a preferably, though not necessarily, parallelepiped-shaped casing 2; and a laundry drying drum 3, which houses the laundry to be dried, is mounted to rotate freely inside casing 2 about a respective axis of rotation L, and directly faces a laundry loading-unloading opening 2a formed in the front wall of casing 2.
  • Drier 1 also comprises a drive assembly 4 for rotating laundry drying drum 3 about its axis of rotation L; and a door (not shown) hinged to the front wall of casing 2 to rotate to and from a work position closing opening 2a in the front wall to seal laundry drying drum 3.
  • Drier 1 also comprises 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.
  • 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.
  • Hot-air generator 7 also comprises a refrigerant compression device 9, or so-called compressor, which compresses the refrigerant (e.g. adiabatically) so that its pressure and temperature are much higher at the outlet than at the inlet of compression device 9.
  • a refrigerant compression device 9 which compresses the refrigerant (e.g. adiabatically) so that its pressure and temperature are much higher at the outlet than at the inlet of compression device 9.
  • compression device 9 comprises a mechanical compression member 9a for compressing the refrigerant; and a variable-speed electric motor 9b, the output shaft of which is connected by a transmission (not shown) to mechanical compression member 9a to transmit the rotary movement generated by electric motor 9b to mechanical compression member 9a.
  • compression device 9 may be a rotary compressor, in which mechanical compression member 9a comprises blades rotating freely about an axis of rotation, and is connected to the output shaft of the electric motor, which rotates the blades to compress the gaseous refrigerant.
  • compression device 9 may be a reciprocating compressor, in which mechanical compression member 9a comprises a piston mounted to slide freely, inside a compression chamber of compression device 9, between a suction position and a compression position; and a mechanical transmission device, which converts the rotary movement generated by the electric motor to linear movement of the piston.
  • mechanical compression member 9a comprises a piston mounted to slide freely, inside a compression chamber of compression device 9, between a suction position and a compression position; and a mechanical transmission device, which converts the rotary movement generated by the electric motor to linear movement of the piston.
  • Reciprocating and rotary compression devices are known and therefore not described in detail, except to state that the variable-speed electric motor is preferably, though not necessarily, an inverter motor or brushless motor or any other similar electric motor.
  • hot-air generator 7 also comprises a first heat exchanger 10, or so-called evaporator, located along air-circulating pipe 8 and connected to compression device 9 so that the refrigerant absorbs heat from the airflow from drying drum 3, thus condensing the surplus moisture in the airflow.
  • a first heat exchanger 10 or so-called evaporator
  • Hot-air generator 7 also comprises a second heat exchanger 11, or so-called condenser, located along air-circulating pipe 8 and connected to compression device 9 to receive the refrigerant and so release heat to the airflow into drying drum 3.
  • a second heat exchanger 11 or so-called condenser, located along air-circulating pipe 8 and connected to compression device 9 to receive the refrigerant and so release heat to the airflow into drying drum 3.
