  • Patent number: 9845567
    Abstract: A laundry machine (100) adapted to dry laundry by means of a flow of drying air has a machine cabinet (110) for accommodating components necessary for the operation of the laundry machine (100). Inside the cabinet is a laundry treatment chamber (105) adapted to contain the laundry to be dried. A cabinet top element (125) incorporated at least part of a drying air circuit in fluid communication with the laundry treating chamber through a drying air inlet opening (210) and through a drying air outlet opening (215) formed in the cabinet top element The cabinet top element has a bottom base element (205) and a top cover (240) and, defined in an interspace between the base element and the top cover, a drying air path for the flow of drying air between said drying air inlet opening (210) and said drying air outlet opening (215). The drying air path includes a moisture condensing arrangement (225, 230).

  • Patent number: 9534329
    Abstract: An appliance for drying laundry (100) comprises an appliance cabinet (110), a laundry treatment chamber (105) inside the cabinet, and a drying air recirculation path (245) for causing recirculation of the drying air into/out from the laundry treatment chamber. The drying air recirculation path is at least partly external to the laundry treatment chamber. A drying air moisture condensing and heating system (215,220,225) located in the drying air recirculation path for dehydrating the moisture-laden drying air leaving the laundry treatment chamber and heating the dehydrated drying air before it re-enters into the laundry treatment chamber.

  • Patent number: 9435069
    Abstract: An appliance for drying laundry (100) includes a drying-air moisture-condensing system comprising a heat pump system (215,220,225) with a variable-output compressor (210) having a compression mechanism and an electric motor for driving the compression mechanism. A controller (265) is provided to vary the rotational speed of the electric motor so as to adjust the rotational speed of the compression mechanism in order to maintain constant a power absorbed by the compressor during at least a portion of a drying cycle.

  • Patent number: 9372031
    Abstract: An appliance for drying laundry includes a drying-air moisture-condensing system including a heat pump system with a variable-output compressor, and at least one drying air variable-speed fan for promoting the recirculation of the drying air. The appliance is adapted to perform at least one laundry drying cycle in: at least a first drying mode wherein the compressor is driven to a first compressor mode having a compressor power consumption course and/or a compressor rotational speed course and/or a frequency course of the supply current/voltage of the compressor motor and the fan is driven to a first fan mode having a speed course, and at least a second drying mode wherein the compressor is driven to a second compressor mode comprising a compressor power consumption course and/or a compressor rotational speed course and/or a frequency course of the supply current/voltage of the compressor motor and the fan is driven to a second fan mode having a speed course.
