[0020] The utility model will be further described below in combination with the drawings.

[0021] According to the drawings, Figs. 1 to 4As shown in the figure, the water flow pressurizing mechanism for the dishwasher comprises a pressurizing spray arm assembly in communication with the water inlet pipe. The pressurizing spray arm assembly comprises a spray arm 1 and a pressurizing impeller 2. The spray arm 1 is provided with a guide pipe opening 11, a guide flow cavity 12 and a pressurizing guide cavity 13. The guide pipe opening 11 is arranged at the bottom of the spray arm 1 and is pivotally connected with the water inlet pipe. The guide flow cavity 12 is arranged in the spray arm 1. The pressurizing guide cavity 13 is arranged at the top of the spray arm 1. The pressurizing impeller 2 is pivotally connected with the shaft in the pressurizing guide cavity 13. The pressurizing guide cavity 13 is provided with a water inlet 14 and a water jet hole 15. The guide pipe opening 11, the guide flow cavity 12, the water inlet 14, the pressurizing guide cavity 13 and the water jet hole 15 are sequentially communicated and form a pressurizing guide flow path which rotates with the spray arm 1 and drives the pressurizing impeller 2 to rotate to increase the water flow speed.

[0022] The pressurizing spray arm assembly has the advantages that when the spray arm 1 is rotated by the water flow reaction force, the water flow enters the pressurizing guide flow path of the spray arm 1. Under the pressurizing rotation of the pressurizing impeller 2, the water flow impact degree in the spray arm 1 component is increased, the water flow pressure of the spray arm 1 component is improved, the cleaning effect is greatly improved, and the cleaning quality of the dishwasher is ensured.

[0023] Referring to Figs. 1 to 4 Further refinement is shown in the figure that the guide pipe opening 11 is integrally formed on the axis at the bottom of the spray arm 1. The pressurizing guide cavities 13 are distributed on both sides of the guide pipe opening 11 and are integrally formed at the top of the spray arm 1.
