  • FIG. 1 is a cross-sectional view illustrating an air conditioner according to an embodiment of the present invention.
  • a heat exchanger 30 and a fan 40 are disposed inside a case 10 in the air conditioner.
  • a front air intake portion 11 can be formed in front of the case 10, and a top air intake portion 12 can be formed in an upper side of the case 10.
  • a filter 13 for filtering air introduced into the air conditioner can be disposed next to the front air intake portion 11 and the top air intake portion 12.
  • a front cover 20 can be coupled to the front side of the case 10 to open and close the front air intake portion 11.
  • the lower side of the front cover 20 is coupled to a hinge 21 and so rotatably coupled. Therefore, when the front cover 20 is opened, the introduced air flows from the upper portion to the lower portion of the front cover 20.
  • a motor unit is coupled to the lower portion of the front cover 20, but the motor unit is not shown in Fig. 1.
  • the top air intake portion 12 can be provided in the form of a grill having a plurality of holes.
  • An inlet louver (not shown) can be disposed to open and close the top air intake portion 12 when the inlet louver rotates.
  • An air outlet 15 can be formed in the lower portion of the case 10.
  • a discharge louver 16 can be disposed at the air outlet 15 to control a discharge direction or angle of air exiting the air conditioner.
  • the discharge louver 16 can be controlled such that it is closed when the air conditioner stops.
  • the fan 40 is disposed in the vicinity of the heat exchanger 30.
  • the fan 40 may be a cross-flow fan that discharges air introduced in a radial direction to a radial direction.
  • the heat exchanger 30 surrounds air intake sides of the fan 40.
  • the heat exchanger 30 includes refrigerant tubes 32 through which refrigerant flows, and a plurality of heat exchange pins 31 through which the refrigerant tubes 32 pass.
  • the heat exchanger 30 is disposed to surround the air intake portion of the fan 40.
  • the heat exchanger 30 may include a plurality of heat exchange portions 35, 36, and 37, which are arranged at different angles within the case 10 and surround the air intake portion of the fan 40.
  • the heat exchanger 30 includes a plurality of heat exchange portions 35, 36, and 37 which are disposed at angles, as shown, for example, in Fig. 1, a relatively large heat exchange surface area, and consequently, a relatively large heat exchange capacity, can be achieved.
  • the heat exchanger 30 can be formed in one piece which has a bent shape.
  • a dividing member 50 can be disposed to divide air introduced to the heat exchanger
  • the dividing member 50 can be disposed between the front air intake portion 11 and the top air intake portion 12.
  • the dividing member 50 blocks off air of the top air intake portion 12 flowing to the lower air intake portion.
  • the dividing member 50 has a panel shape formed long along a lengthwise direction of the cross-flow fan 40.
  • a stabilizer 61 is disposed at a discharge side of the fan 40 to prevent air of the air outlet portion 15 from flowing backward to the heat exchanger 30.
  • a rear guide 62 is disposed at an intake side of the fan 40 to swiftly guide air that has passed through the heat exchanger 30 to the fan 40.
  • the stabilizer 61 and the rear guide 62 are separated by a predetermined distance from the outer periphery of the fan 40.
  • An intake amount reducing member 70 for reducing an intake amount of air is disposed at a portion of the air intake portion.
  • the intake amount reducing member 70 is disposed at a position along the air intake portion 11 which is the closest to the fan, in this case, in front of the heat exchange portion 35.
  • the heat exchange portion 35 is located at a position where a distance between the fan 40 and the air intake portions 12 and 13 is relatively close.
  • the intake amount reducing member 70 is disposed at the heat exchange portion 35 to minimize concentration of an air intake amount because the air intake force of the fan 40 is highest in the vicinity of the heat exchange portion 35.
  • the intake amount reducing member 70 can be installed to the front or rear side of the filter 13 of the front air intake portion 11.
  • the intake amount reducing member 30 can be disposed between the filter 13 and the heat exchanger 30.
  • the intake amount reducing member 70 may include a plurality of bars having a thin and long panel shape. The intake amount reducing member 70 relatively reduces an opening of the front air intake portion 11.
  • FIG. 2 is an enlarged view illustrating an example of the intake amount reducing member 70 shown in Fig. 1.
  • the intake amount reducing member 70 includes a plurality of bars which are disposed lateral to spaces between the refrigerant tubes 32 of the heat exchanger 30.
  • the intake amount reducing member 70 reduces the amount of air passing through a portion of the heat exchanger 30.
  • the ratio between the width W of the intake amount reducing member 70 and the pitch P of the refrigerant tubes 32 can be selected to be optimal depending on the size of the heat exchanger 30 and the capacity of the fan 40.
  • the front cover 20 and the discharge louver 16 are opened, and the fan 40 rotates. As the fan 40 rotates, a low pressure lower than an atmospheric pressure is formed inside the case 10.
  • Air is introduced into the front air intake portion 11 and the top air intake portion 12.
  • the dividing member 50 blocks separates the air introduced through the front air intake portion 11 and the top air intake portion 12, so that air introduced through the top air intake portion 12 is allowed by the dividing member 50 to pass through the upper parts of the uppermost heat exchange portion 37 and an intermediate heat exchange portion 36. Therefore, since a relatively large amount of introduced air passes through the upper heat exchange portion 37 and the intermediate heat exchange portion 36, heat exchange efficiency and the velocity of air can increase relatively at the upper heat exchange portion 37 and the intermediate heat exchange portion 36.
  • FIG. 3 is a partial enlarged view illustrating another example of the intake amount reducing member.
  • an intake amount reducing member 80 includes a plurality of bars which are disposed at angle with respect to the heat exchanger 30. As the intake amount reducing member 80 is disposed to have the slope, air introduced through the front air intake portion 11 can be swiftly guided to the lowermost heat exchange portion 35 to reduce a noise caused by air flowing.
  • the sides of the intake amount reducing member 80 can be rounded to reduce air resistance.
  • the intake amount reducing member 80 can also be disposed between the refrigerant tubes 32.
  • a difference between the velocity of the air passing through the lowermost heat exchange portion 35 and the velocity of the air passing through the uppermost and the intermediate heat exchange portions 36 and 37 can be relatively reduced. Therefore, the heat exchange efficiency of the heat exchanger 30 can be made uniform, and the air discharge performance of the fan 40 can be improved.
