Spray arm for a dishwasher and dishwasher

Abstract

The utility model relates to a kind of spray arm and cleaning machine for cleaning machine, including the body extending along length direction, the body is provided with the flow channel of inside hollow, the body bottom wall is arched to form slag-scraping structure in the flow channel at near end portion, and slag-scraping structure includes the slag-scraping flow channel that gradually inclines downwards from the body end portion to the center, and the lower end of slag-scraping flow channel is formed with the body bottom wall and is inclined to form the slag-scraping port of the width greater than slag-scraping flow channel cooperation.The part of body bottom is arched to form slag-scraping structure in the flow channel, i. e. the concave structure of slag-scraping structure, avoid the interference of other structures under spray arm, it is favorable to improve space utilization;Slag-scraping structure includes the inclined extension of slag-scraping flow channel, and the structure makes slag-scraping water column more concentrated, it is favorable to improve the impact of slag-scraping water column, improve slag-scraping effect;The lower end of slag-scraping flow channel is formed with the body bottom wall and is inclined, to form the slag-scraping port of the width greater than slag-scraping flow channel, can reduce the obstruction to slag-scraping water column, further improve slag-scraping effect.
