Definitions

  • the present invention relates to a laundry dryer comprising a thermoelectric heat pump.
  • the drying air sucked from the outer environment is passed over the laundry by means of a fan and the laundry is dehumidified. Afterwards, the humid drying air is passed over the condenser and leaves its water vapor. The drying air dehumidified is then heated by being passed over the heater, thus it is delivered unto the laundry in a hot and dry state. This process is repeated in a closed cycle and the laundry is provided to be dried at the end of the process.
  • laundry dryers generally air cooled type condensers are used. The air sucked from the outer environment is delivered to the condenser and thus the drying air passing through the condenser is provided to be condensed by being cooled.
  • thermoelectric heat pumps are used in addition to the condenser and the heater.
  • the thermoelectric heat pumps have a hot side that provides the drying air to be heated and supports the main heater, and a cold side that provides the drying air to be cooled and condensed and supports the condenser.
  • the drying air is cooled a little while being passed over the condenser and then is passed over the thermoelectric heat pump.
  • the process of dehumidifying the drying air is realized in two stages.
  • the heating process is also realized in two stages.
  • the drying air which is dehumidified by passing over the condenser and the cold side of the thermoelectric heat pump, is heated a little by being passed over the hot side of the thermoelectric heat pump and afterwards the heating process is completed by the drying air being passed over the main heater.
  • the aim of the present invention is the realization of a laundry dryer which comprises a thermoelectric heat pump, the efficiency of which is increased by decreasing the pressure losses that occur in the drying cycle
  • the entire drying air leaves the drum and is cooled by being passed over the condenser that is placed prior to the thermoelectric heat pump in the drying channel. Some of the air passed over the condenser is passed over the hot side of the thermoelectric heat pump, and the remainder of the air is passed first over the cold side of the thermoelectric heat pump, then over the hot side of the thermoelectric heat pump.
  • the laundry dryer of the present invention comprises a first drying channel that guides some of the drying air leaving the condenser directly to the hot side of the thermoelectric heat pump without passing over the cold side of the thermoelectric heat pump, and a second drying channel that guides the remainder of the air that does not enter into the first drying channel, to the cold side of the thermoelectric heat pump.
  • the laundry dryer furthermore comprises a guide that guides the drying air leaving the cold side to the hot side. The drying air that directly enters into the hot side and the drying air that is transferred from the cold side to the hot side by means of the guide join at the hot side. Thus, the entire drying air leaving the drum is provided to be passed over the hot side of the thermoelectric heat pump.
  • the flow path of the drying air that is passed over the condenser and directly guided to the hot side by means of the first drying channel is shortened, thus pressure losses that may occur due to the distance are prevented.
  • the flow path of the drying air that leaves the condenser in a cooled state technical problems that may occur due to the increase in heat at the hot side of the thermoelectric heat pump are prevented.
  • the flow path of the drying air that flows through the second drying channel is increased, and it is provided to pass over the cold side at a lower speed.
  • the condensation efficiency is provided to be increased in compliance with the operating principle of the cold side of the thermoelectric heat pump.
  • the laundry dryer of the present invention comprises a condenser that is placed into the drying channel prior to the first drying channel and the second drying channel.
  • two condensers are used, that are positioned as spaced apart.
  • the first condenser is placed almost at the outlet of the drum, in the drying channel in the vertical direction so that their inlet openings face the same direction as the drying air, and the second condenser is mounted into the second drying channel so that their inlet openings face the same direction as the drying air.
  • Both condensers are positioned prior to the thermoelectric heat pump.
  • the first condenser is positioned in the first drying channel and the second condenser into the second drying channel so as to be parallel to the first condenser, both prior to the thermoelectric heat pump.
  • the distance covered by the drying air, especially by the drying air directly delivered to the thermoelectric heat pump is decreased, thus the number of pressure losses that may occur at the hot side is decreased.
  • an additional space is obtained, that provides the heights of the heat exchangers of the cold and hot sides of the thermoelectric heat pump located at the lower part of the drum, to be increased.
