Description

Technical Field

[0001] The utility model relates to the technical field of washing machines capable of washing tableware and / or fruits and vegetables, and in particular to a water flow system for washing machines and the washing machine. Background Art

[0002] At present, the upper spray arm connection pipe of the washing machine for washing dishes and / or fruits and vegetables in the industry is generally installed on the bowl basket. After the bowl basket is placed in the washing chamber, the upper spray arm connection pipe is then connected to the water supply pipe located on the side wall of the washing chamber, so as to transport washing water from bottom to top. Because the bowl basket may need to be adjusted in height during use, or the bowl basket needs to be removed from the tank body in order to facilitate the placement of dishes on the bowl basket, the upper spray arm connection pipe and the water supply pipe need to be movably connected.

[0003] For example, in the "Water Distribution Structure, Internal Water Pipe Structure and Dishwasher" disclosed in the Chinese utility model patent with patent number CN202121506706.7 (publication number CN215191361U), the water distribution structure is suitable for the internal water pipe, and the side wall of the water outlet end of the internal water pipe is provided with a water outlet. The water distribution structure includes: a ball storage tank, which is arranged on the internal water pipe and located above the water outlet, and the outer side of the ball storage tank is a closed structure; a water distribution ball is configured to be able to move between the ball storage tank and the water outlet, and can move from the position of the water outlet to the ball storage tank under the action of water pressure, and move from the ball storage tank to the water outlet when the water pressure at the water outlet drops, and close the water outlet under the action of water pressure. When the upper bowl basket in the dishwasher is taken out, the upper spray arm water pipe is detached from the water outlet, and the upper spray arm water pipe is separated from the internal water pipe. At this time, the water distribution ball moves toward the outside of the water outlet under the action of water pressure, and then can block the water outlet, thereby avoiding water spraying, and the dishwasher can operate normally.

[0004] From the above, it can be seen that after the upper bowl basket is raised, that is, when the upper spray piece is disconnected from the inner water pipe, the water outlet on the inner water pipe is blocked by the water distribution ball to reduce water flow loss. This is generally done at present, and the use mode of the inner water pipe is single. Utility Model Content
