Spraying arm assembly for dish washing machine

Abstract

The invention discloses a spraying arm assembly for a dish washing machine. The spraying arm assembly comprises a spraying arm and a rotating stopping plate, wherein a hollow cavity is formed in the spraying arm; a water feeding hole for feeding water, a first thrust spraying hole for pushing the spraying arm to rotate in the first direction, and a second thrust spraying hole for pushing the spraying arm to rotate in the second direction are formed in the spraying arm, wherein the second direction is opposite to the first direction; the rotating stopping plate is rotatably arranged into the spraying arm and can be switched between the first state and the second state; when the rotating stopping plate is in the first state, the first thrust spraying hole is blocked and the hollow cavity and the second thrust spraying hole can be communicated; when the rotating stopping plate is in the second state, the second thrust spraying hole can be blocked and the hollow cavity and the first thrust spraying hole can be communicated. According to the spraying arm assembly, the rotating stopping plate can be simply rotated to enable the spraying arm to rotate in the first direction or the second direction; the control is convenient; the spraying arm is stable to rotate.

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 ...
