  • the dryer may include the cabinet 1 and a drum 2, and may include a circulation flow channel 5 for circulating air of the drum 2 to the outside, and a heat pump 6 accommodated in the circulation flow channel 5 to condense air and re-heat air. Water condensed by the heat pump 6 may be collected in a water storage tank 9 using a pump 8. In one example, even when the driver 3 generates a vibration or a temporary external force is transmitted via the driver 3, a bottom surface 12 of the cabinet 1 may be prevented from being deformed or inclined.
  • the driver 3 may include a motor 34 fixed to the bottom of the cabinet 1, a rotation shaft 37 rotating by the motor 34, a pulley 35 rotated by the rotation shaft 37, and a belt 36 disposed to connect an outer circumferential surface of the drum 2 with an outer circumferential surface of the pulley 35.
  • such dryer has a problem in that a rotational acceleration of the motor 34 is limited to a level equal to or lower than a predetermined level, and has a fundamental limit that the motor 34 should slowly accelerate or decelerate such that the belt 36 does not slip when the drum 2 is rotated.

  • the driver may refer to a combination of the reducer 600 and the motor 500 as described above.
  • the driver may refer to only the motor 500. That is, a component that generates the power and transmits the rotational power to the drum may be referred to as the driver.
  • the driver may be mounted in the mounting portion 425.
  • the mounting portion 425 may support a load of the driver.
  • the driver may be connected to the drum 200 while being supported by the mounting unit 425.
  • the duct 423 may accommodate therein a portion of the drum rear surface 220.
  • the duct 423 may form the flow channel through which air flows together with the drum rear surface 220.

  • the reducer 600 may convert the power of the motor 500 to rotate the drum 200.
  • the reducer 600 may be disposed between the motor 500 and the drum 200 to receive the power from the motor 500, convert the power, and transfer the converted power to the drum 200.

  • the reducer 600 may include therein a gear assembly that rotates in engagement with the driving shaft to convert an RPM of the driving shaft and increase a torque, and the gear assembly may be connected to the drum rotating shaft that is coupled to the drum 200 to rotate the drum. Accordingly, when the driving shaft 530 rotates, the drum rotating shaft 530 may rotate at a lower RPM than the drum rotating shaft but may rotate with a greater torque.
  • a performance of the reducer 600 may depend on whether the driving shaft and the drum rotating shaft are able to remain coaxial with each other. That is, when the driving shaft and the drum rotating shaft are misaligned to each other, there is a risk that coupling of components constituting the gear assembly inside the reducer 600 to at least one of the driving shaft and the drum rotating shaft may be loosened or released.

  • the drum rotating shaft may be misaligned along arrangement of the laundry.
  • the drum rotating shaft may vibrate with a vibration amplitude different from that of the stator 510 or may be inclined at a different angle. Accordingly, the drum rotating shaft and the driving shaft may not be able to remain coaxial with each other.
  • a vibration amplitude at which the motor 500 and the rear plate 420 vibrate may be greater than a vibration amplitude at which the drum rotating shaft vibrates. Even in this case, the drum rotating shaft and the driving shaft may not be able to remain coaxial with each other.
  • the motor 500 is fixed only to the reducer 600 without being fixed to another component of the laundry treating apparatus, when the vibration or the external force is transmitted to the driver, the motor 500 may always be inclined or vibrate simultaneously with the reducer 600 when the reducer 600 is inclinded or vibrates.
  • the reducer 600 and the motor 500 may be designed to be disposed along the first axis M1 parallel to the ground when no load is applied to the drum 200 or the motor 500 is not operated.
  • the vibration occurs in the drum 200 or the motor 500, the vibration is transmitted to the reducer 600 and the reducer 600 is inclined, so that the reducer 600 may be temporarily inclined along the second axis M2.
  • the reducer 600, the motor 500, and the drum 200 may be arranged in parallel along the first axis M1, and then the reducer 600 may be inclined parallel to the third axis M3 because of the vibration of the drum 200 or the motor 500.
  • the third axis M3 may pass through the reducer 600 coupled to the rear plate 420. Because the reducer 600 and the motor 500 are coupled to each other, the motor 500 may also be inclined in parallel with the third axis M3 in the same manner as the reducer 600.
  • a seal 450 may be disposed between the drum rear surface 220 and the rear plate 420.
  • the seal 450 may seal a space between the drum rear surface 220 and the rear plate 420 such that air introduced into the duct 423 of the rear plate 420 is not discharged to the outside and flows into the suction hole 224.
  • the seals 450 may be disposed on the outer surface and the inner surface of the duct 423, respectively.
  • a first seal 451 may be disposed on an outer side in the radial direction of the duct 423
  • a second seal 452 may be disposed on an inner side in the radial direction of the duct 423.
  • the first seal 451 may prevent hot air from leaking outward in the radial direction at a location between the drum rear surface 220 and the duct 423

  • the first seal 451 may be disposed on the outer side in the radial direction of the suction hole 224, and the second seal 452 may be disposed on the inner side in the radial direction of the suction hole 224.
  • the seal 450 is in contact with both the drum rear surface 220 and the rear plate 420. Because the drum 200 rotates during the operation of the laundry treating apparatus, continuous friction is applied to the seal 450 by the drum rear surface 220. Therefore, it is preferable that the seal 450 is made of a material that may seal the space between the drum rear surface 220 and the duct 423 without deteriorating in performance with the presence of a frictional force and a frictional heat generated based on the rotation.
  • the motor 500 or the reducer 600 may be coupled to the rear plate 420 from the rear. Because the rear plate 420 may be made of the thin steel plate material, the rear plate 420 may be bent or deformed by the load transferred to the reducer 600 because of the reducer 600 and the drum 200. That is, the rigidity of the rear plate 420 needs to be secured to install the reducer 600, the motor 500, and the like.
