Dehumidifier and centrifugal blower thereof

Abstract

A dehumidifier includes a body having inlet and outlet ports and a centrifugal fan mounted inside the body to circulate air. The centrifugal fan includes a fan disk coupled to a fan motor such that the fan disk can be rotated, and the fan disk includes an incline inclined toward the outlet ports to guide the flow of air passing through the centrifugal fan to the outlet ports. The incline extends from a motor coupling part of the fan disk, which is coupled to the fan motor, in the radial direction. Blades are mounted at the outer circumference of the incline.

       6 . The dehumidifier according to  claim 5 , wherein each outlet port further includes a side outlet part formed in each side surface of the body while being connected to the inclined outlet part. 
   
   
       7 . The dehumidifier according to  claim 1 , wherein the body includes a protrusion protruding outward to maintain a predetermined distance between the outlet ports and a wall when the body is positioned adjacent to the wall. 
   
   
       8 . The dehumidifier according to  claim 1 , wherein the inlet ports are formed in opposite sides of a front part of the body. 
   
   
       9 . The dehumidifier according to  claim 1 , further comprising a heat exchanger mounted within the interior space of the body to remove moisture from a room air received through the inlet ports. 
   
   
       10 . The dehumidifier according to  claim 9 , wherein the heat exchanger comprises:
 an evaporator to absorb heat and condense moisture from the room air; and   a condenser to supply heat to the air passing through the evaporator.   
   
   
       11 . The dehumidifier according to  claim 1 , wherein the inlet ports comprise two inlet ports each including a filter mounted therein to remove foreign matter contained in the received room air. 
   
   
       12 . A dehumidifier comprising:
 a body including outlet ports formed in opposite sides of a rear part of the body; and   a centrifugal fan mounted in the body to circulate air, wherein the centrifugal fan includes a motor coupling part, which is coupled to a fan motor, an incline extending from the motor coupling part in a radial direction thereof and inclined toward the outlet ports to naturally guide the flow of air toward the outlet ports, and blades mounted at the incline.   
   
   
       13 . A centrifugal blower mounted in a dehumidifier to circulate air, the centrifugal blower comprising:
 a fan motor; and   a fan disk coupled to the fan motor such that the fan disk can be rotated, wherein the fan disk includes an incline inclined toward outlet ports of the dehumidifier to guide the flow of air toward the outlet ports.   
   
   
       14 . The centrifugal blower according to  claim 10 , wherein the fan disk further includes a motor coupling part, coupled to the fan motor, and the incline extends from the motor coupling part in a radial direction of the fan disk. 
   
   
       15 . A dehumidifier, comprising:
 a body having a front portion including at least two inlet ports to intake air at different angles with respect to each other and a rear portion including at least two outlet ports to discharge the air therein outside the body at different angles with respect to each other; and   a heat exchanging unit to dehumidify the air in the body before the air is discharged through the at least two outlet ports.   
   
   
       16 . The dehumidifier according to  claim 15 , further comprising a blower device disposed between the heat exchanging unit and the at least two outlet ports to draw the air through the at least two inlet ports and the heat exchanging unit and to distribute the heat exchanged air to each of the at least two outlet ports. 
   
   
       17 . The dehumidifier according to  claim 16 , wherein the blower device comprises:
 a disk-shaped portion that extends in a curved shape from a central portion toward the rear portion of the body;   a motor coupling part disposed at the center of the blower device to couple with a motor; and   blades extending along the outer periphery of the disk shaped portion and disposed to draw the dehumidified air into the blower device in an axial direction with respect to the disk-shaped portion and to blow the dehumidified air radially outward along a surface of the disk-shaped portion toward the at least two outlet ports.   
   
   
       18 . A method of dehumidifying air the method comprising:
 introducing room air through inlet ports disposed at different angles in a back portion of a body;   passing the room air through a heat exchanger in a first direction to remove moisture from the air; and   blowing the air passing through the heat exchanger toward a plurality of directions other than the first direction and out of a plurality of outlet ports disposed at different angles in a front portion of the body.   
   
   
       19 . The method of  claim 18 , wherein passing the room air through the heat exchanger further comprises passing the air first through a condenser to supply heat to the room air and then through an evaporator to absorb heat and condense moisture from the room air.
