Abstract

The invention is applicable to the field of dishwashers and discloses a dishwasher spray arm and a dishwasher, wherein the dishwasher spray arm includes a spray arm body with a hollow inner cavity, a water inlet and several water spray holes, and the hollow inner cavity Along the direction of water flow, it can be divided into several water spraying channels directly opposite to each water spraying hole and several non-water spraying channels respectively adjacent to each water spraying channel. The cross-sectional area of ​​each water flow in the same non-water spraying channel is equal; and There is a relationship Si=Si+1+Ai between the water flow cross-sectional areas of the two non-spray channels adjacent to the two sides of any spray channel, where Ai is the spray cross-sectional area of ​​the spray hole directly opposite to a water spray channel , Si is the water flow cross-sectional area of ​​the non-spray channel adjacent to one side of the water spray channel and located between the water spray channel and the water inlet, and Si+1 is the non-spray channel adjacent to the other side of the water spray channel cross-sectional area of ​​the flow. It improves the water flow efficiency of the spray arm by optimizing the design of the hollow inner cavity.

Description

technical field [0001] The invention belongs to the field of dishwashers, in particular to a dishwasher spray arm and a dishwasher with the spray arm. 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 achieve a fan-sha...
