Description

Technical Field

[0001] The utility model relates to a washing machine for washing tableware and / or fruits and vegetables. Background Art

[0002] At present, the water pipe of the upper spray arm of the dishwasher in the industry is generally installed on the bowl basket. After the bowl basket is placed in the washing chamber, the upper spray arm is connected with the inner water pipe located on the side wall of the washing chamber, so as to transport the washing water from bottom to top. Because the height of the bowl basket may need to be adjusted during use, or the bowl basket needs to be removed from the washing chamber to facilitate the placement of tableware on the bowl basket, so a movable connection is required between the spray arm and the inner water pipe.

[0003] For example, the Chinese utility model patent with patent number CN202220208703.3 (publication number CN216984829U) discloses a "cleaning machine", which includes a box body with a washing chamber inside; a shelf that can be placed in the washing chamber; an upper spray arm that can be rotatably arranged in the washing chamber, and the upper spray arm can be located above the shelf; a water pump mechanism that is arranged at the bottom of the box body; the water pipe includes a lower pipe body, a first end of which is fluidically connected to the water pump mechanism, and the second end of the lower pipe body extends into the washing chamber; an upper pipe body, a first end of which is rotatably connected to the upper spray arm, and the second end of the upper pipe body passes downward through the shelf and is detachably connected to the second end of the lower pipe body, and the upper pipe body is fluidically connected to the lower pipe body. By designing the water pipe to be split into an upper pipe body and a lower pipe body, and the two are detachably connected, the upper pipe body can be removed together with the upper spray arm without interfering with the removal of items on the shelf.

[0004] In order to facilitate the connection between the upper tube body (equivalent to the connecting tube below) and the lower tube body (equivalent to the inner water pipe below), the lower tube body needs to always protrude from the side wall of the washing chamber and be located in the washing chamber. In this way, when the storage rack (i.e., the bowl basket) is vertically placed in or taken out of the washing chamber, the storage rack is easy to collide with the lower tube body, affecting the normal placement of the storage rack. In addition, because the storage rack needs to avoid the lower tube body, the size of the storage rack needs to be made smaller, which will result in a smaller number of tableware that can be placed on the bowl basket.
