Spray arm assemblies for dishwashers

Abstract

The invention discloses a spray arm assembly for a dishwasher, comprising: a spray arm, a hollow cavity is defined in the spray arm, and a water inlet hole for water inlet is provided on the spray arm, and the spray arm is used to push the spray arm along the The first thrust nozzle hole rotating in the first direction and the second thrust nozzle hole used to push the spray arm to rotate in the second direction, the second direction is the opposite direction of the first direction; the rotating blocking plate is rotatably arranged In the spray arm and switch between the first state and the second state, when the rotating block is in the first state, the first thrust nozzle is blocked and the hollow inner cavity and the second thrust nozzle are connected, and the rotating block is in the first state In the second state, the second thrust nozzle hole is blocked and the hollow inner chamber and the first thrust nozzle hole are connected. According to the spray arm assembly for the dishwasher in the embodiment of the present invention, the spray arm can be rotated in the first direction or the second direction only by turning the rotating blocking plate, which is convenient to control and the spray arm rotates stably.

Description

technical field [0001] The invention relates to the technical field of washing appliances, in particular to a spray arm assembly for a dishwasher. Background technique [0002] A household dishwasher is an intelligent appliance that is suitable for ordinary families and can replace manual cleaning of tableware. Generally speaking, the dishwasher water pump circulates water to each spray arm, and the spray arm rotates while spraying high-temperature and high-pressure water to wash and clean the tableware in all directions. Function, to achieve the dual effect of cleaning and sterilization. [0003] At present, in most cases, the horizontal rotation direction of the spray arm in the dishwasher is fixed, that is, the spray arm always rotates in the same direction (such as counterclockwise), so that the direction and angle of washing the tableware are relatively single. This single flushing method is likely to cause under-washing positions between the tableware, which affects ...
