Heat pump dishwasher

Abstract

The present invention relates to a dishwasher comprising a body; a heat pump that is disposed inside the body, that provides the heating of the water to be used in the washing step and that has a first heat exchanger drawing heat from the ambient air, a second heat exchanger transferring the heat received from the first heat exchanger to the wash water and a compressor fluidly connected to the first heat exchanger and the second heat exchanger, realizing the refrigerant cycle by compressing and directing the refrigerant leaving the first heat exchanger to the second heat exchanger, and a drip tray that is disposed immediately under the first heat exchanger, wherein the water condensing on the first heat exchanger is collected.

1 . A dishwasher comprising a body; a heat pump that is disposed inside the body, that provides the heating of the water to be used in the washing step and that has a first heat exchanger drawing heat from the ambient air, a second heat exchanger transferring the heat received from the first heat exchanger to the wash water and a compressor fluidly connected to the first heat exchanger and the second heat exchanger, realizing the refrigerant cycle by compressing and directing the refrigerant leaving the first heat exchanger to the second heat exchanger, and a drip tray that is disposed immediately under the first heat exchanger, wherein the water condensing on the first heat exchanger is collected, characterized by a duct wherein the refrigerant is circulated, that extends between the compressor, the first heat exchanger and the second heat exchanger; a valve that is disposed on the duct and that enables the refrigerant to be directed to the first heat exchanger or the second heat exchanger and a control unit that, by directing the compressed refrigerant leaving the compressor by means of the valve to the first heat exchanger, enables the first heat exchanger to become a heat source and thus providing the evaporation of the water collected in the drip tray. 
     
     
         2 . A dishwasher as in  claim 1 , characterized by the control unit that enables the compressed refrigerant leaving the compressor after the washing step to be directed to the first heat exchanger. 
     
     
         3 . A dishwasher as in  claim 2 , characterized by the control unit that enables the water used in the washing step to be circulated over the second heat exchanger after the compressed refrigerant leaving the compressor after the washing step is directed to the first heat exchanger. 
     
     
         4 . A dishwasher as in  claim 1 , characterized by the control unit that enables the compressed refrigerant leaving the compressor after the rinsing step to be directed to the first heat exchanger . 
     
     
         5 . A dishwasher as in  claim 4 , characterized by the control unit that enables the water used in the rinsing step to be circulated over the second heat exchanger after the compressed refrigerant leaving the compressor after the rinsing step is directed to the first heat exchanger. 
     
     
         6 . A dishwasher as in  claim 1  characterized by the control unit that enables the compressed refrigerant leaving the compressor during the drying step to be directed to the first heat exchanger. 
     
     
         7 . A dishwasher as in  claim 6 , characterized by the control unit that enables the water vapor generated during the drying step to be passed over the second heat exchanger. 
     
     
         8 . A dishwasher as in  claim 1 , characterized by the drip tray wherein the water condensing on the second heat exchanger in the drying step is collected. 
     
     
         9 . A dishwasher as in  claim 1 , characterized by a fan that is disposed in the vicinity of the drip tray and that enables the ambient air to be blown towards the drip tray. 
     
     
         10 . A dishwasher as in  claim 9 , characterized by the fan that enables the hot air around the compressor to be directed towards the drip tray. 
     
     
         11 . A dishwasher as in  claim 1 , characterized by the four-way valve.
