  • the heat pump comprises a first heat exchanger which absorbs heat from the environment so as to enable the water used in the washing step to be heated; a second heat exchanger which transfers the heat received from the first heat exchanger to the washing tub; and a compressor which performs the refrigerant cycle between the first heat exchanger and the second heat exchanger.
  • the dishwasher of the present invention comprises a closure member which prevents the air, the heat of which is absorbed by the heat pump, from being delivered behind the body.
  • the closure member By means of the closure member, the cooled-down air is not delivered behind the body.
  • the heat exchange with the interior of the washing tub is prevented, and the heat in the washing tub is insulated.
  • the dishwasher comprises the closure member which is disposed on the lower edge of the body between the body and mounting gap where the body is disposed.
  • the dishwasher comprises the closure member which is a shutter opening in one direction.
  • One edge of the closure member in the form of a shutter can open in one direction by making a constant circular movement on the body.
  • the area behind the dishwasher can be reached when desired.
  • the cold air is prevented from reaching behind the dishwasher.
  • the dishwasher comprises the closure member having dimensions which can be adjusted depending on the distance between the body and the mounting gap.
  • the dimensions of the closure member can be changed depending on the dimensions of the mounting gap and the dishwasher. Consequently, the space between the mounting gap and the body is completed closed.
  • the dishwasher comprises the closure member in the form of an accordion. Thanks to being in the form of an accordion with foldable surfaces, the closure member can be adjusted depending on the distance between the mounting gap and the body. Moreover, since the surface area increases, the cold air is enabled to hit a larger surface area, thus dampening any noise.
  • the dishwasher comprises the closure member which is manufactured from a layered insulation material.
  • the insulation material can be easily separated from the areas predetermined by the manufacturer, and thus the dimensions thereof can be adjusted.
  • the dishwasher comprises a spring which is disposed between the mounting gap and the body, and the closure member which moves depending on the spring.
  • the spring shortens and lengthens depending on the distance between the mounting gap and the body, thus the dimensions of the closure member can be changed.
  • the dishwasher comprises a screw which is disposed between the mounting gap and the body, and the closure member which moves depending on the screw.
  • the screw moves depending on the distance between the mounting gap and the body, thus the dimensions of the closure member can be changed.
  • a dishwasher comprises a closure member which completely closes the distance between the mounting gap and the body.
  • the dishwasher (1) comprises a body (2); a washing tub (3) that is disposed in the body (2) and wherein the washing process is performed; and a heat pump (7) which is arranged under the washing tub (3) and which has a first heat exchanger (4) enabling the water to be used in the washing step to be heated by drawing heat from the environment, a second heat exchanger (5) transferring the heat received from the first heat exchanger (4) to the washing water and a compressor (6) fluidly connected to the first heat exchanger (4) and the second heat exchanger (5) so as to realize the refrigerant cycle.
  • the heat pump (7) the air in the washing tub (3) is dehumidified and sent back into the washing tub (3).
  • the water droplets remaining on the kitchen items in the washing tub (3) after the washing process can be removed more quickly, thereby improving the drying performance
  • the dishwasher (1) of the present invention comprises a closure member (8) which prevents the air cooling down as the heat pump (7) draws the heat of the ambient air from being delivered behind the body (2).
  • the first heat exchanger (4) draws heat from the environment and transfers the same to the second heat exchanger (5) to heat the water. Therefore, the temperature of the air leaving the first heat exchanger (4) decreases.
  • the closure member (8) By means of the closure member (8), the delivery of the cooled-down air behind the body and the heat exchange with the washing tub (3) are prevented.
  • the heat in the washing tub (3) is insulated.
  • the dishwasher (1) comprises the closure member (8) which is disposed on the lower edge of the body (2) between the body (2) and the mounting gap where the body (2) is disposed.
