AI Technical Summary
Existing rectangular-cabin dishwashers have a problem with spray dead zones, which limits the length of the spray arms and increases the cost of additional water supply and water control.
A spray arm structure including a main spray arm, a first auxiliary spray arm, and a fixed gear was designed. The rotation of the auxiliary spray arm is realized through a transmission gear set, thereby expanding the spray area to cover the dead corners of the rectangular inner tank.
It effectively solves the problem of spray dead corners in rectangular inner tanks, avoids the additional cost of water supply and water control, and reduces production costs.
