Outdoor unit for air conditioning device

Abstract

A spray nozzle of an outdoor unit is provided with: an air guide portion through which air flows; a water guide portion through which water flows and which causes the air flowing through the air guide portion to flow into water to form water containing a large number of bubbles; and a spray portion that is located downstream of the water guide portion in a direction of water flow and sprays, to the outside, the water containing a large number of bubbles which is formed in the water guide portion.

1 . An outdoor unit for an air conditioning device, comprising:
 a heat exchanger; and   a spray nozzle for spraying water to air flowing toward the heat exchanger,   wherein the spray nozzle has:   an air guide portion through which air flows;   a water guide portion through which water flows and which causes the air flowing through the air guide portion to flow into water to form water containing a large number of bubbles; and   a spray portion that is located downstream of the water guide portion in a direction of water flow and sprays, to the outside, the water containing a large number of bubbles which is formed in the water guide portion.   
     
     
         2 . The outdoor unit for an air conditioning device according to  claim 1 , wherein
 the water guide portion has a pipe wall shaped into a pipe and also has one or a plurality of air introduction holes penetrating the pipe wall in a thickness direction, and   the air guide portion is shaped into a pipe so as to surround an outer circumference of the water guide portion.   
     
     
         3 . The outdoor unit for an air conditioning device according to  claim 2 , wherein
 the water guide portion has the plurality of air introduction holes, and   the plurality of air introduction holes are provided at intervals in a circumferential direction of the water guide portion and a direction in which the water guide portion extends.   
     
     
         4 . The outdoor unit for an air conditioning device according to  claim 1 , wherein
 the water guide portion is shaped into a pipe and has, at least partially, a porous portion, and   the air guide portion is shaped into a pipe so as to surround an outer circumference of the water guide portion.   
     
     
         5 . The outdoor unit for an air conditioning device according to  claim 4 , wherein the porous portion is formed from foam metal. 
     
     
         6 . The outdoor unit for an air conditioning device according to  claim 1 , wherein
 the water guide portion is shaped into a pipe, and   the air guide portion is shaped into a pipe and has a leading end portion thereof connected to the water guide portion.   
     
     
         7 . The outdoor unit for an air conditioning device according to  claim 6 , wherein the air guide portion has a porous portion at a leading end portion thereof. 
     
     
         8 . The outdoor unit for an air conditioning device according to  claim 1 , further comprising:
 a charger that electrically charges water sprayed from the spray nozzle.   
     
     
         9 . The outdoor unit for an air conditioning device according to  claim 1 , wherein the water guide portion vertically guides water containing bubbles. 
     
     
         10 . The outdoor unit for an air conditioning device according to  claim 9 , wherein
 the spray nozzle is disposed outside the heat exchanger in the outdoor unit,   the water guide portion guides water containing bubbles downward, and   the spray portion is disposed on a lower side of the water guide portion and sprays, downward, the water containing a large number of bubbles which is guided by the water guide portion.   
     
     
         11 . The outdoor unit for an air conditioning device according to  claim 9 , further comprising:
 a fan that forms flow of air directed toward the heat exchanger,   wherein   the fan is disposed above and inward of the heat exchanger in the outdoor unit and discharges upward, to the outside of the outdoor unit, air that has flowed into the outdoor unit and been subjected to heat exchange by the heat exchanger,   the spray nozzle is disposed further toward an outer side than the heat exchanger in the outdoor unit,   the water guide portion guides water containing bubbles upward, and   the spray portion is disposed on an upper side of the water guide portion and sprays upward the water containing a large number of bubbles which is guided by the water guide portion.
