Abstract

An air-conditioning outdoor unit of the present invention has a pair of primary ports of a four-way switching valve that is connected to a discharge port and an intake port of a compressor. A first secondary port of a pair of secondary ports of the four-way switching valve is connected to an external connection port, and a second secondary port is connected to an outdoor heat exchanger. Flexible pipes, are inserted between the first secondary port and the external connection port and between the second secondary port and the outdoor heat exchanger.

Claims

exact text as granted — not AI-modified
1 . An air-conditioning outdoor unit comprising: 
 a compressor including a discharge port and an intake port;    an outdoor heat exchanger;    an external connection port;    a four-way switching valve including a pair of primary ports respectively connected to the discharge port and the intake port of the compressor and a pair of secondary ports, one of the secondary ports being connected to the external connection port, the other of the secondary ports being connected to the outdoor heat exchanger; and    a plurality of flexible pipes respectively arranged between the one of the secondary ports and the external connection port and between the other of the secondary ports and the outdoor heat exchanger.    
   
   
       2 . The air-conditioning outdoor unit of  claim 1 , wherein 
 the primary ports of the four-way switching valve is directly connected to the discharge port and the intake port of the compressor without an intervening a vibration absorbing mechanism.    
   
   
       3 . An air conditioner comprising: 
 the air-conditioning outdoor unit of  claim 1;  and    an air-conditioning indoor unit including an indoor heat exchanger, the air-conditioning indoor unit being connected to the air-conditioning outdoor unit.    
   
   
       4 . A compressor unit comprising: 
 a compressor including a discharge port and an intake port;    a four-way switching valve having a pair of primary ports respectively connected to the discharge port and the intake port of the compressor and a pair of secondary ports; and    a plurality of flexible pipes respectively connected to the secondary ports of the four-way switching valve.    
   
   
       5 . The compressor unit of  claim 4 , wherein 
 the primary ports the four-way switching valve is directly connected to the discharge port and the intake port of the compressor without an intervening vibration absorbing mechanism.    
   
   
       6 . An air conditioner comprising: 
 the air-conditioning outdoor unit of  claim 2;  and    an air-conditioning indoor unit including an indoor heat exchanger, the air-conditioning indoor unit being connected to the air-conditioning outdoor unit.
