Definitions

  • the present invention relates to a heat pump household appliance wherein the drying process is realized.
  • the drying process is realized by passing the drying air over the items placed in the drying chamber.
  • heat pump drying systems are preferred as the latter generally consumes less energy than the drying systems wherein electric heaters are used for heating the drying air.
  • the heat pump comprises a compressor and an evaporator that provide the circulation of the refrigerant by pressurizing the same, and a condenser.
  • the evaporator in the heat pump collects the moisture in the drying air and the condenser functions as the heater by enabling the drying air to be heated.
  • the aim of the present invention is the realization of a heat pump household appliance wherein the drying air is efFectively heated without adversely affecting the flow rate thereof.
  • a heat pump household appliance wherein the drying process is realized, and comprises a drying chamber wherein the items to be dried are placed; an air duct that enables the drying air to be circulated; an evaporator for retaining the moisture in the drying air circulated in the air duct; a condenser that enables the drying air to be heated, and a compressor that enables the refrigerant to be sucked and pumped.
  • the compressor, the condenser and the evaporator are fluidly connected to each other via delivery pipes.
  • the refrigerant that is pressurized and heated in the compressor is transferred to the condenser by means of a delivery pipe and passed through the refrigerant tubes of the condenser.
  • the refrigerant increases the temperature of the surfaces of the condenser in contact with the drying air and thus, the drying air is heated by the condenser.
  • the pressure and temperature of the refrigerant leaving the condenser is decreased and the refrigerant is enabled to absorb heat from the drying air while passing through the evaporator.
  • the drying air leaves its moisture on the evaporator.
  • the refrigerant leaving the evaporator is transferred back to the compressor by means of a delivery pipe and this cycle is repeated throughout the drying process.
  • the household appliance of the present invention comprises at least one tube-shaped electric heater that is arranged on and wound around the delivery pipe extending between the compressor and the condenser or that is placed in the refrigerant tube of the condenser so as to enable the refrigerant to be heated to
  • the electric heater is produced as a narrow and long tube.
  • the electric heater extends in the refrigerant tube of the condenser or on the delivery pipes outside the air duct so as not to create resistance against the drying air flowing in the air duct.
  • the electric heater enables the amount of the heat transferred by the refrigerant to the surface of the condenser to be increased.
  • the drying air can be efFectively heated without any flow rate loss and without the need for increasing the temperature of the electric heater to higher values.
  • the time spent at the beginning of the drying process for the heat pump system to quickly reach the thermal equilibrium and operate with maximum efficiency is saved, and the hot drying air is enabled to be delivered onto the laundry in the drying chamber at a higher speed.
  • the electric heater extends along the entire length of the refrigerant tube.
  • the tube-shaped electric heater has a length almost equal to that of the refrigerant tube and is placed in the refrigerant tube so as to extend in the refrigerant tube.
  • the electric heater is attached onto at least one delivery pipe.
  • the tube-shaped electric heater is simply placed on the outer surface of the delivery pipe and the refrigerant passed through the delivery pipe is enabled to be heated.
  • the ease of assembly is provided and the electric heater can be integrated to all conventional heat pump systems with different volumes and structural characteristics.
  • the electric heater is wound around the delivery pipe.
  • the total length of the tube-shaped electric heater is increased and a sufficient amount of heat can be transferred to the refrigerant especially in smaller heat pump systems.
  • the efficiency of the heat pump is increased by heating the refrigerant.
  • the drying air can be efFectively heated without placing a heater reaching high temperatures into the air duct. Consequently, safety hazards that may be caused by the overheating of the heater and the pressure loss that may occur in the drying air while being passed over the heater are prevented in a simple and cost-effective manner.
  • the household appliance (1) comprises a body (2); a drying chamber (3) arranged in the body (2) and wherein the drying process is realized; an air duct (4) that is connected to the drying chamber (3) and that enables the drying air to be circulated, and a heat pump (11) that has a compressor (5) enabling the refrigerant to be sucked and pumped, an evaporator (6) enabling the moisture in the drying air in the air duct (4) to be removed, a condenser (7) enabling the dehumidified drying air to be heated, with at least one serpentine shaped refrigerant tube (9) through which the refrigerant is circulated, and delivery pipes (8) through which the refrigerant is circulated and that enables the compressor (5), the evaporator (6) and the condenser (7) to be fluidly connected to each other.

  • the electric heater (10) is operated intermittently during the drying process so as to enable the temperature of the refrigerant to be kept at high levels.
  • the surface temperature of the condenser (7) is increased by means of the refrigerant heated by the electric heater (10) and the temperature of the drying air passed over the condenser (7) is enabled to quickly and effectively reach high levels.
