The invention belongs to the technical field of accessories for washing machines, and discloses a washing ball. The washing ball comprises a containing cavity used for storing a clothes treating agent; the adding opening is formed in the washing ball and communicates with the containing cavity; the discharging opening is formed in the position, opposite to the adding opening, of the washing ball; when the clothes treating agent is added into the containing cavity, the discharging opening is in a
closed state, and when the clothes washing ball is placed into the washing cylinder, the discharging opening is opened along with rotation of the washing cylinder. According to the clothes washing ball provided by the invention, when a user adds a clothes treating agent into the clothes washing ball, the
discharge port is closed, and the accommodating cavity forms a semi-
closed cavity for accommodating the clothes treating agent. When the washing ball is placed in the washing cylinder, the
discharge port is opened along with rotation of the washing cylinder, and the clothes treating agent in the containing cavity can flow into the washing cylinder through the adding port and can also flow into the washing cylinder through the
discharge port. According to the scheme, a discharging channel of the clothes treating agent is additionally arranged, and therefore the situation that the clothes treating agent is left in the containing cavity is avoided.
