Definitions

  • the present general inventive concept relates to an air conditioner and, more particularly, to an air conditioner, designed to have uniform air volume and velocity across an indoor discharge port.
  • Korean Patent Laid-open Publication No. 2005-18384 discloses an air conditioner which comprises an indoor unit and an outdoor unit provided as an integral component.
  • the air conditioner is formed at a front side with an indoor suction port through which indoor air is drawn into a body of the air conditioner, and at a lateral side of the indoor suction port with an indoor discharge port through which conditioned air is discharged.
  • the air conditioner of the disclosure comprises an indoor heat exchanger inside the indoor suction port to heat-exchange indoor air, an indoor blowing fan behind the indoor heat exchanger to blow heat-exchanged air to the indoor discharge port, and a blower case to guide the air blown by the indoor blowing fan to the indoor discharge port.
  • FIG. 1 illustrates a blower case of the air conditioner as described above.
  • the blower case 1 comprises a fan receipt space 3 to receive an indoor blowing fan 2 , and a discharge guide space 4 to guide discharged air to an indoor discharge port (not shown).
  • the discharge guide space 4 is communicated with the fan receipt space 3 .
  • the indoor blowing fan 2 received in the fan receipt space 3 is a typical multi-blade type centrifugal fan.
  • the air conditioner since the air circulates in a rotational direction of the indoor blowing fan 2 while flowing from the fan receipt space 3 of the blower case 1 to the discharge guide space 4 , the air conditioner has a problem in that the discharged air is concentrated at a lower side of the discharge guide space 4 (a lower right side in FIG. 1 ). In other words, due to a concentration of the discharged air at the lower right side in the indoor discharge port caused by circulation of air flow, distribution in air velocity is not uniform across the indoor discharge port. In addition, since the air velocity is higher at a lower portion than at an upper portion of the indoor discharge port, blowing noise can occur therefrom.
  • the present general inventive concept provides an air conditioner which has uniform volume and air velocity of air discharged through an indoor discharge port, and which suppresses blowing noise from being generated from the indoor discharge port.
  • an air conditioner which includes a blower case to guide air blown by a blowing fan to an indoor discharge port, wherein the blower case includes a discharge guide space to guide discharged air to the indoor discharge port, and an air distribution member positioned in the discharge guide space to guide distribution of the discharged air.
  • the blower case may include a fan receipt space to receive the blowing fan and communicates with the discharge guide space.
  • the air distribution member may include a plurality of air distribution plates separated from each other and fixed to an inner surface of the discharge guide space.
  • the plurality of air distribution plates may be arranged in parallel with a blowing direction of air, and integrally formed with the blower case.
  • the air conditioner may further include a body having a suction port and a discharge port formed at a front side thereof, and a heat exchanger positioned inside the suction port, wherein the blower case and the blowing fan are positioned behind the heat exchanger.
  • the blowing fan may be a centrifugal fan.
  • a blower case usable with an air conditioner including a fan port to contain a fan therein, a discharge guide space adjacent to the fan port to receive blown air from the fan within the fan port, the discharge guide space including air distribution units spaced apart from each other within the discharge guide space to evenly distribute the received blown air.
  • a blower case usable with an air conditioner including a housing including a fan to intake air from outside through an indoor heat exchanger, an air discharge region to receive the air from the fan and to discharge the air back outside; and air distribution plates distributed at predetermined positions within the air discharge region to evenly distribute the received air while being discharged outside.
  • an air conditioner including a blower case including a fan to intake air from outside, an air discharge region to receive the air from the fan and to discharge the air back outside, and air distribution plates distributed at predetermined positions within the air discharge region to evenly distribute the received air while being discharged outside.
  • the air conditioner may further include an indoor heat exchanger positioned adjacent to an indoor side of the blower case such that the air being taken in by the fan passes therethrough; and an indoor discharge port positioned adjacent to the air discharge region to receive the evenly distributed air from the air discharge region and to discharge the air back outside.
  • the the air distribution plates may be positioned at predetermined angles with respect to each other.
  • the air distribution plates are integrally formed with the air discharge region.
  • the air distribution plates are fixed to the air discharge guide region.
  • FIG. 1 is a perspective view illustrating a blowing fan of a conventional air conditioner
  • FIG. 2 is a perspective view illustrating an air conditioner in accordance with an embodiment of the present general inventive concept
  • FIG. 3 is an exploded perspective view illustrating the inner configuration of the air conditioner.
  • FIG. 4 is a perspective view illustrating a blowing fan of the air conditioner.
  • an air conditioner includes a body 10 having a rectangular shape.
  • the body 10 includes an upper case 11 , which includes an upper side and opposite sides integrally formed with the upper side, a bottom panel 12 , a front panel 13 , and a rear panel (not shown).
  • the front panel 13 is positioned at an indoor side, while the rear panel is positioned at an outdoor side.
  • the front panel 13 of the indoor side is formed with an indoor suction port 14 and an indoor discharge port 15 to provide suction and discharge of indoor air
  • the upper case of the outdoor side is formed at the upper and opposite sides with an outdoor suction port 16 to provide suction of outdoor air.
  • the rear panel is formed with an outdoor air discharge port.
  • An indoor heat exchanger 17 to provide heat exchange of indoor air is positioned inside the indoor suction port 14 of the front panel 13
  • an indoor blowing fan 18 to provide blowing of indoor air is positioned behind the indoor heat exchanger 17
  • the air conditioner further includes a cover 19 which is positioned behind the indoor heat exchanger 17 and has an air suction port 19 a to guide air passing through the indoor heat exchanger 17 to an inflow side of the indoor blowing fan 18 , and a blower case 20 which is positioned behind the cover 19 to receive the indoor blowing fan 18 while guiding air blown by the indoor blowing fan 18 to the indoor discharge port 15 .
  • a control box 30 in which various electronic components are received is positioned near the indoor discharge port 15 , and an adjusting handle 31 is positioned below the indoor discharge port 15 of the front panel 13 and connected with the control box 30 .
  • a partition plate 32 is positioned behind the blower case 20 to divide an inner space of the body 10 into an indoor side space and an outdoor side space.
  • the outdoor side space of the body 10 (behind the partition plate) is provided with an outdoor heat exchanger 33 and an outdoor blowing fan 34 to provide heat exchange and circulation of outdoor air.
  • the air conditioner further includes a motor 35 to drive the indoor blowing fan 18 and the outdoor blowing fan 34 , and a compressor 36 to compress a circulating refrigerant, which are positioned behind the partition plate 32 .
  • the blower case 20 surrounding the indoor blowing fan 18 has a parallelepiped-box shape, the front side of which is open, as illustrated in FIG. 4 .
  • the blower case 20 is provided with a fan receipt space 21 to receive the indoor blowing fan 18 , and a discharge guide space 22 to guide discharged air to the indoor discharge port 15 .
  • the indoor blowing fan 18 is a multi-blade type centrifugal fan, and the fan receipt space 21 is configured to surround an outer periphery of the indoor blowing fan 18 .
  • the fan receipt space 21 communicates with the discharge guide space 22 such that air flows to the discharge guide space 22 via operation of the indoor blowing fan 18 .
  • the discharge guide space 22 has a round inner surface in order to easily guide air blown from the indoor blowing fan 18 to the indoor discharge port 15 at the front side.
  • the blower case 20 further includes an air distribution member to guide discharged air such that the discharged air can be uniformly distributed in an overall region of the indoor discharge port 15 .
  • the air distribution member can include a plurality of air distribution plates 23 separated from each other and fixed to an inner surface of the discharge guide member 22 .
  • the air distribution plates can be arranged parallel to a blowing direction of air so as to guide distribution of discharged air, and can be integrally formed with the blower case 20 during a process of forming the blower case 20 .
  • the indoor blowing fan 18 and the outdoor blowing fan 34 rotate. Then, indoor air is drawn into the body 10 through the indoor suction port 14 of the front panel 13 via operation of the indoor blowing fan 18 , and is heat-exchanged through the indoor heat exchanger 17 . The heat-exchanged indoor air is discharged through the indoor discharge port 15 via the fan receipt space 21 and the discharge guide space 22 . At this time, as illustrated in FIG. 4 , since air flow is guided by the plural air distribution plates 23 during blowing of the air from the fan receipt space 21 to the discharge guide space 22 , the air is discharged in a uniformly distributed state across an overall area of the indoor discharge port 15 .
  • the air conditioner of the present inventive concept can reduce blowing noise caused by the discharged air, since it is possible to maintain the volume of the discharged air constant while preventing the discharged air from being concentrated at a specific position of the indoor discharge port 15 .
  • Outdoor air is drawn into the body 10 through the outdoor suction port 16 via operation of the outdoor blowing fan 34 , and is then heat-exchanged through the outdoor heat exchanger 33 .
  • the heat-exchanged outdoor air is discharged through an outdoor discharge port at the rear side of the body 10 .
