Laundry treatment appliance with a compressor cooling line in parallel with processing air line

Abstract

The present invention relates to a laundry treatment appliance ( 1 ) comprising a drum wherein the laundry to be processed is placed and a machine compartment ( 2 ) wherein a circulation fan ( 8 ) circulating the processing air and a compressor ( 3 ) realizing the refrigerant cycle in communication with an evaporator ( 5 ) and a condenser ( 6 ), are disposed. An intermediate region ( 7 ) is provided in between the evaporator ( 5 ) and the condenser ( 6 ) so as to establish a compressor cooling line.

1 . A laundry treatment appliance ( 1 ) comprising a drum wherein the laundry to be processed is placed and a machine compartment ( 2 ) wherein a circulation fan ( 8 ) circulating the processing air and a compressor ( 3 ) realizing the refrigerant cycle in fluid communication with an evaporator ( 5 ) and a condenser ( 6 ), are disposed, characterized in that a cooling ring ( 9 ) in contact relationship with the compressor ( 3 ) encircling the same is provided in air communication with an intermediate region ( 7 ) extending between said evaporator ( 5 ) and said condenser ( 6 ) and with an exit side of the condenser ( 6 ). 
     
     
         2 . A laundry dryer ( 1 ) as in  claim 1 , characterized in that said cooling ring ( 9 ) is in air communication with a by-pass line inlet channel ( 10 ) and a by-pass line outlet channel ( 11 ). 
     
     
         3 . A laundry dryer ( 1 ) as in  claim 2 , characterized in that said intermediate region ( 7 ) in between the evaporator ( 5 ) and the condenser ( 6 ) is a separation line into which the by-pass line inlet channel ( 10 ) opens. 
     
     
         4 . A laundry dryer ( 1 ) as in  claim 2 , characterized in that the processing air from the intermediate region ( 7 ) is directly transferred to frontal impact area of the circulation fan ( 8 ) by means of said by-pass line outlet channel ( 11 ). 
     
     
         5 . A laundry dryer ( 1 ) as in  claim 4 , characterized in that the cooling ring ( 9 ) is a ring-like annular member in annular contact relationship with said compressor ( 3 ). 
     
     
         6 . A laundry dryer ( 1 ) as in  claim 3 , characterized in that the processing air from the intermediate region ( 7 ) is directly transferred to frontal impact area of the circulation fan ( 8 ) by means of said by-pass line outlet channel ( 11 ). 
     
     
         7 . A laundry dryer ( 1 ) as in  claim 1 , characterized in that the cooling ring ( 9 ) is a ring-like annular member in annular contact relationship with said compressor ( 3 ). 
     
     
         8 . A laundry dryer ( 1 ) as in  claim 2 , characterized in that the cooling ring ( 9 ) is a ring-like annular member in annular contact relationship with said compressor ( 3 ). 
     
     
         9 . A laundry dryer ( 1 ) as in  claim 3 , characterized in that the cooling ring ( 9 ) is a ring-like annular member in annular contact relationship with said compressor ( 3 ). 
     
     
         10 . A laundry dryer ( 1 ) as in  claim 6 , characterized in that the cooling ring ( 9 ) is a ring-like annular member in annular contact relationship with said compressor ( 3 ).
