Spraying arm assembly of dish-washing machine and dish-washing machine with spraying arm assembly

Abstract

The invention discloses a spraying arm assembly of a dish-washing machine and the dish-washing machine with the spraying arm assembly. The spraying arm assembly of the dish-washing machine comprises a water supply pipe, a sliding spraying arm base, a spraying arm and a driving assembly. The sliding spraying arm base is slidably arranged on the water supply pipe in the longitudinal direction. The spraying arm is rotatably arranged on the sliding spraying arm base, a spraying arm cavity communicated with the water supply pipe is formed in the spraying arm, and spraying holes communicated with the spraying arm cavity are formed in the spraying arm. The driving assembly is used for driving the sliding spraying arm base to slide. By means of the spraying arm assembly of the dish-washing machine, the washing range can be expanded.

Description

technical field [0001] The invention relates to the technical field of washing appliances, in particular to a spray arm assembly of a dishwasher and a dishwasher with the spray arm assembly. Background technique [0002] At present, cabinet-type household dishwashers can be generally divided into 60 machines and 45 machines according to the width, and the widths of the two are about 60 cm and 45 cm respectively. Since the depths of the two machines are approximately the same, correspondingly, the horizontal section of the internal washing area of ​​the 60 machine is close to a square, while the 45 machine is a rectangular area. The spray arm of the dishwasher rotates horizontally to rinse the tableware, so the coverage of the spray arm is close to a circle, which will make it easy to form an underwash area at the four corners inside the dishwasher, especially for the 45 machine. In addition to the four corners, the washing effect of the front and rear positions of the washi...

AI Technical Summary

Problems solved by technology

The spray arm of the dishwasher rotates horizontally to rinse the tableware, so the coverage of the spray arm is close to a circle, which will make it easy to form an underwash area at the four corners inside the dishwasher, especially for the 45 machine. In addition to the four corners, the washing effect of the front and rear positions of the washing area is also lacking, which affects the overall washing effect of the dishwasher.

[0003] Further, if the outer spray hole is specially set up for spraying and flushing the under-washing area, the outer spray hole will occupy part of the washing water, but when the spray arm is in other positions, the outer spray hole will directly spray to the outside and inside of the washing area. It will cause waste of washing water resources and increase the noise level, which will have a negative impact on the energy consumption, water consumption and noise of the dishwasher
