Problems solved by technology

But the problem is that the reliability and stability of the active connection only relying on the snap ring and the buckle are relatively poor. During the washing process, the rotation speed will be unstable due to changes in water pressure, and in severe cases, the rotating spray arm may fall off.

Abstract

The invention provides a rotary spray arm installing structure for a water tank cleaning machine. The rotary spray arm installing structure comprises a rotary spray arm mounted at the bottom of a water tank inner cavity, and a vertical rotating shaft part is disposed at the lower end of the rotary spray arm. The rotary spray arm installing structure further comprises a spray arm fixing column vertically fixed in the upper portion of the water tank bottom plate for the spray arm to install, and a spray arm installing base connected with the spray arm fixing column, the rotary shaft part is rotatably installed on the spray arm installing base though mounting nuts; the rotary shaft part is relatively fixed with the mounting nuts by a limiting component arranged along the circumferential direction. The rotary spray arm installing is more reliable and more stable.

Description

technical field [0001] The invention relates to the field of cleaning machines, in particular to a rotating spray arm installation structure for a sink type cleaning machine. Background technique [0002] With the advancement of technology, various small dishwashers have been listed and are gradually entering ordinary families. In order to save space, there have been many sink-type cleaning machine designs. Existing sinks are refitted into cleaning machines, directly using the sink as the washing space, and generally a rotating spray arm is arranged at the bottom of the tank cavity. The rotating spray arm in the prior art is installed through an additional bracket, and the lower end of the rotating spray arm is usually provided with a rotating shaft, a snap ring is provided on the outer peripheral surface of the rotating shaft, and a snap ring is provided in the installation port of the rotating arm seat. Buckle, the rotating spray arm is movably connected with the swing ar...
