Definitions

  • An object of one embodiment of the present disclosure is to provide a DD dryer capable of securing a space within a case and increasing degree of freedom in flow path design by disposing a motor in a space outside a case instead of an inner space of the case in which a drum is installed.
  • the first planet gear and the second planet gear may have the same radius and a height (or thickness) of the second planet gear may be greater than that of the first planet gear.
  • the dryer may include a flow path duct coupled to the rear case on an outside of the rear case so as to form an air flow space with the rear case in between by covering the air intake area and the air supply area.
  • a prescribed section for supplying air into the drum may be preferably provided to a rear case outside, i.e., a case outside through the flow path duct.
  • the dryer includes a connector provided between the stator and the rear case to fix the stator to the rear case and forming a front-rear space between the stator and the rear case.
  • the first sun gear is located in front of the rotor shaft and formed with the rotor shaft as an integral part.
  • the drive unit may include a power transfer unit transferring a rotation force of the rotor to the drum and the power transfer unit may be provided between the rotor and the drum.
  • the power transfer unit may preferably transfer power so that the rotor and the drum can have the same axis.
  • a portion of the connector may be inserted in the hollow part of the stator. Therefore, the stator may be fixed to the connector more solidly by stamping.
  • the first carrier, the second sun gear and the middle shaft may be formed as an integral part.
  • the heated air is guided into the flow path duct, which is a drying outside, by the blower fan.
  • the heated air enters the drum from the rear side of the drum through the flow path duct.
  • the air heat-exchanged in the drum is discharged through the front side of the drum.
  • the discharged humid air is changed into dry air in a manner of being cooled in an evaporator of the heat pump to condense moisture, and the dry air is headed in a condenser of the heat pump.
  • the heated air enters the drum again.
  • an air circulation structure may be configured.
  • the stator 280 is preferably provided to an outside of the rear case 130.
  • the stator 280 is preferably provided as fixed to the outside of the rear case 130.
  • the rear case 130 is configured to form an appearance of the dryer on the rear side of the dryer 10 and also form an inner space of the dryer.
  • the rear case 130 is configured to be fixed.
  • the stator 280 is fixed to the outside of the rear case 130, it can be fixed solidly.
  • the decelerator housing 231 may be fixed and coupled to the rear side of the rear case 130.
  • the drum shaft perforated hole 232 of the decelerator housing 231 may be further extended in the front direction by passing through the shaft perforated hole 130a.
  • the drum rear wall and the drum shaft 210 are coupled together.
  • the rotor 270 and the rotor shaft 220 are coupled together.
  • the holes 26 are not formed in the radial bridges 27 and the circumferential bridge 28. Therefore, as a support structure supportive of the air intake area 24 of the mesh type attributed to a plurality of the holes 26, the radial bridges 27 and the circumferential bridge 28 may be formed. Preferably, to reinforce self-rigidity, the radial bridges 27 and the circumferential bridge 28 may be formed convex in front or rear direction.
  • the inner gasket 40 includes a fixing part 41 and an extension part 42, and a fastening part 43 may be formed in the fixing part 41.
  • the inner gasket 40 may be mounted on an inner surface of the rear case through the fixing part 41 and the fastening part 43, and the extension part 42 may be formed in a manner of being extended from the fixing part 41 in a direction of the drum rear wall 22.
  • the extension part 42 is configured to contact with the drum rear wall, whereby sealing can be performed.
  • the extension part 42 may be slantly extended toward an inside from a radial outside. Namely, the extension part 42 may be located on a radial inside of the fixing part 41.
  • the extension part 42/52 of the inner/outer gasket 40/50 may be slantly extended from the fixing part 41/51 toward the drum rear wall. Through this, air sealing may be performed while the frictional force between the rotating drum and the end of the extension part 42/52.
  • a plurality of openings 260a may be formed in the rotor 260. As the rotor rotates, air may flow into the rotor from an outside of the rotor. The inflow air may flow toward the stator 280.
  • the fastening part 231c may be provided to the rear housing 231b.
  • the rear housing 231b is inserted in the hollow part 250a of the connector and then coupled and fixed to the connector 250 through the fastening part 231c.
  • the first planet gear 223 is provided rotatably centering on a roller shaft 222, and the roller shaft 222 may be fixed to a first carrier 243.
  • a first carrier supporter 224 may be provided for the front-rear position fixing of the first planet gear and the fixing of the roller shaft.
  • the first planet gear 223 may be rotatably provided to the first carrier 243.
  • the first planet gear 223 revolves around the first sun gear 221, the first carrier 243 rotates.
  • the middle shaft 241 may configure an integral part with the first carrier 243 and the second sun gear 242. Namely, they may include a single component or part. Hence, the middle shaft 241 and the first carrier 243 may rotate as an integral part. This means that a rotation speed of the first carrier is different from a rotation speed of each of the rotor shaft and the drum shaft.
