  • the cross flow blower has suction ports 201 in upper side and ceiling part, and a blowing port 202 in lower side, and a draft path 203 is formed between the suction ports 201 and the blowing port 202.
  • a detachable air filter 206 Inside the draft path 203, a detachable air filter 206 to be inserted to the ceiling side position of a main body base frame 205, heat exchangers 207 disposed at front side and back side, and a cross flow fan 208 located inside enclosed by the heat exchangers 207 are disposed along the inner side of a front cover 204.
  • the cross flow fan 208 is composed by arranging plural blades 209 in a columnar form to form an impeller, and assembling a plurality of impellers in the direction or axis of rotation.
  • a stabilizer 211 located closely and oppositely to the cross flow fan 208, and a rear guide 213 forming a diffuser 212 extending from the cross flow fan 208 to the blowing port 202 between it and the stabilizer 211 are arranged.
  • Part of the rear guide 213 and the stabilizer 211 forms a drain pan 214 for receiving dehumidified water dropping from the heat exchangers 207.
  • the blowing port 202 comprises a vertical guide blade 215 for controlling the direction of air flow blowing out into the room in the vertical direction, and a lateral guide blade 216 for controlling in the lateral direction.
  • the vertical guide blade 215 is positioned inside of the diffuser 212 in most part, during a normal operation. When the operation is stopped, the vertical guide blade 215 forms the contour of the blower and is hence formed in a plate shape along the contour line.
  • a coupling beam 217 for moving the lateral guide blade 216 by interlock is disposed orthogonally to a rotary shaft 218 of the lateral guide blade 216.
  • the air flow blown out from the cross flow fan 208 passes through the vertical guide blade 215 and is separated, and collides at the leading end of the vertical guide blade 215. This has been was the cause of increase of noise. Moreover, at the upper side and lower side of the vertical guide blade 215, front edge peeling occurs and the flow rate performance is decreased significantly. The same also occurs in the coupling beam 217 for moving the lateral guide blade 216 by interlock. The coupling beam 217 is also a severe resistance to flow, and the flow rate performance is decreased greatly.
  • the cross flow blower of the invention is characterized by installing a cross flow fan having impellers composed of plural blades arranged in a columnar form, inside a casing which forms a draft path inside comprising suction ports and a blowing port; disposing a stabilizer and a rear quide which form a diffuser from the cross flow fan and the blowing port; and forming a vertical guide blade for controlling the stream of air flow in the vertical direction at the blowing port, wherein the vertical guide blade is disposed so that 1/2 or more of chord length may be present outside of the diffuser in a normal operation state.

  • the vertical guide blade has the front edge formed in an arc form in a sectional shape, and the upper side and lower side are in a shape smoothly continuous through the front edge.
  • the vertical guide blade is formed in an elliptical or oblong form in a sectional shape.
  • the vertical guide blade is in a shape suited to mass production by resin material.

  • the draft resistance given by the coupling beam to the air flow is minimum, and no increase of noise caused by collision of air flow against the leading end of the front edge of the coupling beam occurs, and occurrence of large peeling at the upper side and lower side of the coupling beam is prevented, and the flow rate performance is enhanced.
  • the coupling beam is formed in an elliptical or oblong form in a sectional shape.
  • the noise caused by collision of air flow against the leading end of the coupling beam is further suppressed, and peeling at the upper side and lower side of the coupling beam is further suppressed, the draft resistance is decreased, and the flow rate performance is enhanced.
  • the coupling beam is disposed at a position immediately before the upstream side of the vertical guide blade.
