Dish washing machine and spraying arm assembly thereof

Abstract

The invention discloses a dish washing machine and a spraying arm assembly thereof. The spraying arm assembly comprises a fixed gear, a main spraying arm, a mobile gear and an auxiliary spraying arm; the fixed gear is provided with a water inlet; the main spraying arm is connected with the fixed gear and can pivot around the center axis of the fixed gear; a first spraying chamber is formed in the main spraying arm; the outer surface of the main spraying arm is provided with a thrust hole and a plurality of first spraying holes; the mobile gear is connected with the main spraying arm; the mobile gear is meshed with the fixed gear so as to drive the mobile gear to pivot around the center axis of the mobile gear and pivot around the center axis of the fixed gear; the auxiliary spraying arm is connected with the mobile gear and synchronously moves along with the mobile gear; a second spraying chamber is limited in the auxiliary spraying arm; the peripheral surface of the auxiliary spraying arm is provided with a plurality of second spraying holes. According to the spraying arm assembly of the dish washing machine, the change of the spraying arms into the two-dimensional rotation from the one-dimensional rotation can be implemented and accordingly the cleaning rate is improved and the spraying arms are not integrally-formed parts any more, the auxiliary spraying arm can be formed by two separated parts especially, and accordingly the manufacturability is improved and the cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of dishwashers, more specifically, to a spray arm assembly of a dishwasher and a dishwasher with the spray arm assembly. Background technique [0002] In the related art, the spray arm used in the bowl machine is a one-dimensional rotating spray arm. The angle of the water sprayed by this spray arm is fixed, and it is difficult to clean the dead corner of the dishwasher. Therefore, in order to ensure the washing effect, the washing time needs to be lengthened, and the cleaning rate is still not ideal enough. In addition, the entire spray arm is formed as a whole, or the main spray arm and the auxiliary spray arm are respectively formed as a whole, and the structure is relatively complicated. When a certain part or the connection between the two is damaged, it needs to be replaced as a whole. At the same time, the spray arm is manufactured Inconvenient, high manufacturing and maintenance costs. Con...

Problems solved by technology

[0002] In the related art, the spray arm used in the bowl machine is a one-dimensional rotating spray arm. The angle of the water sprayed by this spray arm is fixed, and it is difficult to clean the dead corner of the dishwasher.

Therefore, in order to ensure the washing effect, it is necessary to lengthen the washing time, and the cleaning rate is still not ideal

In addition, the entire spray arm is formed as a whole, or the main spray arm and the auxiliary spray arm are respectively formed as a whole, and the structure is relatively complicated. When a certain part or the connection between the two is damaged, it needs to be replaced as a whole. At the same time, the spray arm is manufactured Inconvenient, expensive to manufacture and repair
