Description of the Related Art Conventionally, in a washing machine, especially a washing machine for combined use of dehydration, a washing tub has a balance ring at the upper portion thereof to serve also as a dehydration tub, and the inner periphery of the balance ring is flexible. A finishing agent injection case, a lint filter, etc. are provided so as to project inward of the washing tub.

[0003]

Therefore, there is a problem in that the water flow at the time of washing hits the water flow passing through the softening agent injecting case or the lint filter to cause water splash to reach the outside of the washing tub. Was there.

The present invention has been made in view of the above circumstances, and therefore an object thereof is that the water flow during washing passes through a softening agent injection case or a lint filter provided on the inner peripheral portion of the balance ring. It is an object of the present invention to provide a washing machine capable of reducing water splash caused by hitting the like.

[0005]

In order to achieve the above object, the washing machine of the present invention is characterized in that recesses are formed on both sides of the protrusion of the balance ring.

In this case, it is advisable to form a rib protruding inward from the washing tub from the portion of the concave portion on the protrusion side to the upper portion.

Further, the ribs may be formed so as to protrude more toward the inside of the washing tub as they go up.

[0008]

[Operation] When the water flow at the time of washing hits the water flow passing through the soft finishing agent injection case and the lint filter provided on the inner periphery of the balance ring, the water splash caused by the water flow was observed, and it was found that the water flow hits the upper part as it is. There was something that bounced outward, hits the inner surface of the balance ring, and then bounces upward.

Therefore, by forming recesses on both sides of the protrusions of the balance ring, the water splashes that bounce outward are temporarily taken into the recesses and changed so as to bounce inward or downward in the washing tub. You can

Further, in this case, in the case where a rib projecting inwardly of the washing tub is formed from the portion of the concave portion on the protrusion side to the upper portion, the rib prevents the water splash taken in the concave portion from going out of the concave portion. Moreover, in this case, the water splash that hits the protrusion or the like and bounces upward as it is can be blocked by the ribs and changed so as to bounce inward of the washing tub or downward.

Further, if the ribs are formed so as to project more toward the inside of the washing tub as they go up, the splash of water splash can be more effectively prevented.
