Definitions

  • the present disclosure mainly relates to an air conditioner for household.
  • an air conditioner includes, within a housing, a cross flow fan having a plurality of blades, a stabilizer, a rear guider, and a heat exchanger.
  • the heat exchanger includes a front heat exchanger disposed on a front side of the cross flow fan and a rear heat exchanger disposed on a rear side of the cross flow fan.
  • Such an air conditioner is configured to suck air from a top surface side of the housing of the air conditioner, exchange heat between the sucked air and a refrigerant flowing inside the heat exchanger, and blow out the air from a bottom surface side of the housing. Accordingly, indoor air conditioning is performed.
  • the air conditioner includes an air blowing passage that allows an air outlet and a suction port to communicate with each other.
  • the air conditioner includes a cross flow fan, a rear guider, a stabilizer, a front heat exchanger, and a rear heat exchanger within the air blowing passage.
  • the cross flow fan includes a plurality of blades.
  • the rear guider includes a proximity portion that approach to face the cross flow fan and is separated from the cross flow fan by a predetermined dimension, and an upper end protrusion that further extends from the proximity portion toward an upper side of the rear heat exchanger.
  • the front heat exchanger is disposed in front of the cross flow fan, and the rear heat exchanger is disposed behind the cross flow fan.
  • the present disclosure provides an air conditioner that rectifies an airflow flowing into a cross flow fan and improves air blowing performance.
  • An air conditioner includes a cross flow fan, a stabilizer, a rear guider, a front heat exchanger disposed at a front side of the cross flow fan, and a rear heat exchanger disposed at a rear side of the cross flow fan.
  • the rear guider includes a proximity portion facing the cross flow fan and disposed to be in vicinity of the cross flow fan at a predetermined distance, and an upper end protrusion extending upward from the proximity portion.
  • the upper end protrusion of the rear guider has an arcuate portion that circumscribes straight line X perpendicular to a downstream surface of the rear heat exchanger.
  • distal end point B When a contact point between straight line X and the arcuate portion is defined as distal end point B, distal end point B is positioned at a side of the cross flow fan with respect to a center line of the upper end protrusion, and when a diameter of the arcuate portion is defined as D and a thickness of the upper end protrusion is defined as T, D/T ⁇ 0.6 is satisfied.
  • the air conditioner of the present disclosure can improve the air blowing performance by improving the turbulence of the airflow flowing into the cross flow fan.
  • Fig. 6 is a longitudinal sectional view of air conditioner 1 according to PTL 1.
  • Fig. 7 is a diagram illustrating a longitudinal sectional configuration near upper end protrusion 6b of air conditioner 1.
  • Fig. 8 is a flowchart illustrating a flow of air near upper end protrusion 6b of air conditioner 1.
