  • the higher the final discharge speed means the greater the vector component in the horizontal direction, the greater the amount of air flowing into the drum 30 through the drum opening 310. This can reduce the risk of air leaking into unnecessary parts.
  • the cross-sectional area of the guider discharge port 821 is preferably 50% or more of the cross-sectional area of the guider inlet 811.
  • the velocity of the discharged air is rather lowered. This is because turbulence occurs even if the cross-sectional area is excessively large due to the characteristics of the fluid.
  • the speed increases to a certain extent, but the speed decreases if it exceeds a certain threshold.
  • the inner surface of the first body 810 and the second body 820 is preferably curved.
  • the inner surface preferably forms mathematically continuous lines and surfaces. If the area is abruptly reduced or protrusions are present, the fluid resistance is rapidly increased, which greatly affects the final discharge speed.
  • FIG. 8 illustrates that the clothes treating apparatus 1 further includes a rib 70.
  • the rib 70 includes a gasket rib 710, a tubbri 720, and a drum rib 730, and when at least one or more of the three types of ribs 70 are provided, the first communication part 610 is provided.
  • the air introduced into the tub 20 can be remarkably prevented from leaking into the space between the tub 20 and the drum 30.
  • Gasket rib 710 is provided on the gasket 50 provided in the tub opening 210, the tub 720 is provided on the inner circumferential surface of the tub front surface 220, the drum rib 730 is the front drum It is provided on the outer peripheral surface of 320.
  • the rib 70 may be installed in the clothes treating apparatus 1 together with the guider 80, and the heated air may be directed only to the clothes inside the drum 30.
