Spray arm device for dish washer and dish washer provided with spray arm device

Abstract

The invention discloses a spray arm device for a dish washer and a dish washer provided with the spray arm device. The spray arm device for the dish washer comprises a spray arm water pipe, a sun gear, a planetary gear, a gear holder and a spray arm body. The sun gear is arranged at the position of a water outlet of the spray arm water pipe, and the position of the sun gear is fixed relative to the spray arm water pipe. The planetary gear is in transmission connection with the sun gear. The gear holder, the sun gear and the planetary gear are arranged on the gear holder in a rotary mode. The spray arm body is connected with the planetary gear in a relatively fixed mode. A spray hole which communicates with the spray arm water pipe is formed in the spray arm body. According to the spray arm device for the dish washer, water entering the spray water pipe can be sprayed out through the spray hole in the spray arm body after passing through the water outlet in the spray arm water pipe. Due to the fact that the spray arm body can rotate on its central axis synchronous with the planetary gear and the spray arm body and the planetary gear can synchronously rotate around the central axis of the gear holder, a predetermined spray track can be formed through the spray hole in the spray arm body, so that tableware can be better washed.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a spray arm device for a dishwasher and a dishwasher having the same. Background technique [0002] In related technologies, the working principle of household dishwashers is: through the rotating spraying of several internal spray arms, the tableware is continuously covered and sprayed and washed, and the tableware is cleaned by combining the effects of water reflection, splashing and flowing. . For general cabinet dishwashers, since the width and depth are close to each other, the shape of the cross-section of the internal washing area is close to a square, while the spraying area reached by the rotation of the general spray arm is circular, making the square The four corners will not be covered, which will obviously affect the overall cleaning effect. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the re...
