Spraying arm of dish washing machine and manufacturing method thereof

Abstract

The invention discloses a spraying arm of a dish washing machine and a manufacturing method thereof. The spraying arm of the dish washing machine comprises a spraying arm body and an installing seat,wherein the spraying arm body comprises a connecting arm and a telescopic arm; the connecting arm is provided with a first cavity; the telescopic arm is provided with a second cavity; the connecting arm is connected with the telescopic arm; the first cavity communicates with the second cavity; the connecting arm is provided with a connecting seat; the connecting seat is arranged on the installingseat; the telescopic arm is provided with annular grooves; each annular groove is provided with a rotating sleeve; the rotating sleeves are rotationally connected with the telescopic arm; each rotating sleeve is provided with a spraying hole; and each spraying hole communicates with the second cavity. The method comprises the following steps of a, preparation; b, assembly of a first transmission shaft and a transmission sleeve; c, installation of the spraying arm body and the rotating sleeves; d, assembly of fixing cases; e, installation of the first transmission shaft and the transmission sleeve; f, installation seat calibration; and g, whole operation detection. The spraying angle of the spraying holes is adjustable, so that the spraying angle is wider; the spraying efficiency is higher;the spraying effect is better; the steps are optimized; the manufacturing steps are simplified; and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of dishwashers, and in particular relates to a spray arm of a dishwasher and a manufacturing method thereof. Background technique [0002] Dishwashers are equipment that automatically clean tableware such as bowls, chopsticks, plates, plates, knives, forks, etc. Household automatic dishwashers are only suitable for families, and mainly include cabinet type, desktop type, and sink integrated type. Using a dishwasher to wash tableware can greatly reduce tedious manual labor. Just put the tableware to be washed into the dishwasher, turn on the faucet, press the button, and do other things with confidence, because the washing process can be completed automatically without anyone waiting. The angle of the spray hole of the existing dishwasher cannot be adjusted, and if the spray hole is fixed, it will make it difficult to spray some places on the dishes, and the spray effect is poor. At the same time, the manuf...

AI Technical Summary

Problems solved by technology

The angle of the spray hole of the existing dishwasher cannot be adjusted, and if the spray hole is fixed, it will make it difficult to spray some places on the dishes, and the spray effect is poor

At the same time, the existing spray arm manufacturing process is cumbersome and the manufacturing accuracy is low, which needs further optimization
