Abstract

The invention is applicable to the field of dishwashers, and discloses a dishwasher spray arm device and a dishwasher, wherein the dishwasher spray arm device includes a rotating conduit and a spray arm rotatably connected to the rotating conduit, and the spray arm has a hollow inner cavity and several water spray holes, the rotating conduit has a water inlet hole communicating with the hollow inner cavity, and a diversion cone opposite to the water inlet hole is protruded in the spray arm, and the diversion cone has a function for guiding the washing water. The diversion cone surface of the flow, the rotating conduit has a drainage tube wall opposite to the diversion cone surface, and an annular shunt channel is formed between the diversion cone surface and the drainage tube wall, and the annular shunt channel can be divided into several along the water flow direction. The water flow section perpendicular to the water flow direction, and the areas of each water flow section are equal. In the present invention, through the setting of the diversion cone, the cross-sectional areas of the water flow in the annular flow channel are equal, thereby reducing the pressure loss when the washing water enters the spray arm, improving the water flow efficiency of the spray arm, and reducing the vortex noise.

Description

technical field [0001] The invention belongs to the field of dishwashers, in particular to a dishwasher spray arm device and a dishwasher with the spray arm device. Background technique [0002] A dishwasher is a machine that uses chemical and physical methods to automatically wash dishes, cups, knives and forks, chopsticks and other tableware, and some dishwashers also have the function of automatically drying the washed tableware. [0003] Specifically, the washing working principle of a commonly used dishwasher is: use the washing pump to perform power suction to transport the washing water to the spray arm through the pipeline at a certain pressure, so that the washing water flows from the spray hole of the spray arm at a certain pressure. The pressure and speed are sprayed out to wash away the dirt on the tableware, so as to achieve the purpose of removing the dirt on the tableware; and in order to make the spray arm rotate continuously during the washing process to ach...
