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 water pipe 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 water 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 tableware on the bowl basket, the upper spray arm water pipe and the water supply pipe need to be movably connected.

[0003] For example, the Chinese utility model patent with patent number CN201820365541.8 (publication number CN209252763U) discloses a spray arm pipe connection structure and a dishwasher. The connection structure includes a movable component for being arranged on the bowl basket and a fixed component for being arranged on the side wall of the dishwashing tank. The movable component includes a water outlet pipe and a movable joint arranged at one end of the water outlet pipe, and the movable joint has a first inclined surface; the fixed joint has a second inclined surface and a water inlet channel, and the water inlet channel is connected to the axial direction of the water outlet pipe. The movable joint and the fixed joint are connected by a plug-in structure. When the plug-in structure is plugged in, the first inclined surface and the second inclined surface cooperate, and the water outlet pipe is connected to the water inlet channel. When the user lifts the bowl basket vertically out of the dishwashing tank, the movable component is lifted out together with the bowl basket. When the user places the bowl basket, the socket in the movable component will buckle the plug column in the fixed component, and the movable joint and the fixed joint are in contact in the form of an inclined surface, which can reduce user misoperation and make the pipe connection good.

[0004] This method is suitable for the bowl basket to be lifted out or put into the bowl sink vertically, because the pipe connection structure is set on the bowl basket, so the pipe connection structure is also lifted out or put into the sink in the same way. In this method, the bowl rack and the spray arm connection pipe connected to it are moved outside the tank, so a special space needs to be set to prevent the bowl rack from being out.

[0005] In addition, if the movable joint is docked with the fixed joint, the two are likely to interfere with each other during the alignment process, causing damage to the components. Utility Model Content
