Description

    Technical Field
  • This invention relates to household appliances comprising a drying system with an enhanced drying efficiency.
    • Prior Art
  • Drying system in appliances with drying function conventionally comprises a condenser unit, an air blower unit and a heater unit. Hot and humid air, coming from the drum which contains the textile articles to be dried, enters into the condenser. The air which is cooled, condensed and dehumidified in the condenser enters into the air blowing device. Dry air diverted to the heater by this device is heated and returned to the drum by the heater, thereby completing the drying cycle which is continued cyclically. The condenser must adequately condense the hot and humid air coming from the drum in order to ensure efficiency in a known drying cycle.
  • The drying device, comprising a known drying system, which is disclosed in the patent application No WO2010060810A1 of the prior art is provided with at least one fan for cooling the condenser of the drying system. Extra energy consumption will occur due to this cooling of the condenser by means of a fan.
  • The drying device disclosed in the patent application No WO2007023510A1 of the prior art comprises a drum containing the textile articles to be dried, a filter for removing such substances as fibres from the air that moves out from the drum, a condenser in which the air is condensed, and a heater. Said device further comprises a cooling unit and a heat exchanger unit positioned in the device in order to ensure a more efficient drying by lowering the heat of the condenser. The cooling unit and the heat exchanger unit operate in collaboration. While the cooling unit cools the condenser, the heat exchanger unit transfers the resulting heat to the air being condensed in the condenser. The cooling unit of said device causes the device to consume more energy and increases cost of production.

    Disclosure of the Invention
  • Figure 1 shows an exemplary household appliance with drying function (G) comprising at least one drum (1). The drying system of this household appliance (G) comprises at least one condenser (2), at least one air blower (3) and at least one heater (4). The humid air in the drum (1) enters into the condenser (2) through at least one air canal (5a). The air, which is condensed and dehumidified in the condenser (2) by giving off heat, is passed through the heater (4) by means of the air blower (3) positioned at the condenser (2) outlet. The air heated by the heater (4) returns to the drum (1) thereby completing the drying cycle which is continued cyclically. The humidity condensed in the condenser (2) is discharged through at least one drainage hole (not shown) provided in the appliance (G).
  • Part of the air which is diverted from the air blower (3) to the heater (4) as illustrated in Figure 1 is returned to the condenser (2) inlet through at least one other air canal (5b), shown by Figure 2 in detail, in order to enhance efficiency of the drying function of said household appliance (G). In this way, the hot and humid air coming from the drum (1) to the condenser (2) inlet mixes with the lightly humid, saturated, cold air leaving from the condenser (2) and diverted to the condenser (2) inlet through said air canal (5b); therefore cools further and is dehumidified, and regular drying cycle continues.
  • Household appliance (G) of the invention, another exemplary embodiment of which is shown in Figure 3, comprises at least one additional condenser (6) positioned between the air canal (5b) at the outlet of the air blower and the condenser (2). Part of the cool air blown by the air blower (3) is diverted to the heater (4) for continuation of the drying function whereas an amount of air passes through said air canal (5b) located at the outlet of the blower (3) and enters into this additional condenser (6). The air cooled and dehumidified in the condenser (6) is returned again to the condenser (2) and mixes with the hot and humid air coming to the condenser (2) from the drum (1). In this way, more efficient cooling and condensing of the air, coming from the drum (1), in the condenser (2) is ensured.
  • In another exemplary embodiment of the invention shown in Figure 4, said appliance (G) comprises at least one housing (7) in which the condenser (2) of the drying system is placed. At least one end of the air canal (5b) located at the outlet of the air blower (3) communicates with this housing (7). In this way, the air that is diverted to the housing (7), in which the condenser (2) is placed, by means of the air blower (3) contacts outer surface of the condenser (2) and cools this surface, ensuring that the hot air passing through the condenser (2) cools and releases more humidity and moves toward the condenser (2) inlet shown by Figure 5 in detail. Hot and humid air coming from the drum (1) through the other air canal (5a) mixes with the lightly humid, saturated, cool air which cools the condenser and the air is further cooled before entering into the condenser (2). Thus, it is ensured that the air entering into the drum (1) is condensed more and drying efficiency is enhanced.
  • In the exemplary embodiment of the invention shown in Figure 4 the air that released humidity and is cooled in the additional condenser (6), which is positioned between the condenser (2) and the air canal (5b) at the air blower (3) outlet, is diverted to said housing (7). Thus, the air that is passed through the additional condenser (6) and is diverted to housing (7) by means of the air blower (3) contacts the outer surface of the condenser (2) and cools this surface and moves toward the condenser (2). Hot and humid air coming from the drum (1) through the other air canal (5a) mixes with this air, which comes from the air blower (3) and cools the outer surface of the condenser (2), and condenses more in the condenser (2), enhancing efficiency of drying.
