The invention discloses a washing equipment drainage channel and washing equipment; the drainage channel is arranged on a washing tub of the washing equipment and guides water from the washing tub tothe outside of the washing tub from top to bottom, the drainage channel comprises a shell, and the shell is provided with a surface structure capable of reducing wind resistance along with the rotation of the washing tub. The windward surface of the shell corresponding to the rotating direction of the washing tub is provided with a smooth curved or plane transition structure. The surface of the shell protruding out of the peripheral wall of the washing tub is in smooth transition connection with the peripheral wall of the washing tub. The shell comprises: the windward surface corresponding onewindward surface, in the rotation direction, of the washing tub; a leeward surface that is the other surface opposite to the windward surface; and a water guide surface positioned between the windward surface and the leeward surface and which is far away from one surface of the peripheral wall of the washing tub, and the windward surface is in smooth transition connection with the peripheral wallof the washing tub. The washing equipment drainage channel and the washing equipment have the advantages that when the washing tub rotates at a high speed, wind resistance can be reduced, noise is reduced, and the rotation balance of the washing tub is maintained.
