Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a water distribution component and a dishwasher. Background Technology

[0002] Dishwashers include a washing motor. Water output from the motor is pressurized and then delivered through various pipes to the spray arms, ultimately creating high-pressure water to rinse the dishes. Related dishwasher technologies typically use a water-dividing assembly to separate the entire dishwasher into independent single-layer washes, thus achieving less water and lower energy consumption. Some dishwashers add fans for drying; however, these fans only dry the washed dishes and cannot dry the water system itself, potentially leading to mold growth due to prolonged dampness in the water system.

[0043] Dishwashers include a washing motor. Water output from the motor is pressurized and then delivered through various pipes to the spray arms, ultimately creating high-pressure water to rinse the dishes. Related dishwasher technologies typically use a water-dividing assembly to separate the entire dishwasher into independent single-layer washes, thus achieving less water and lower energy consumption. Some dishwashers add fans for drying; however, these fans only dry the washed dishes and cannot dry the water system itself, potentially leading to mold growth due to prolonged dampness in the water system.

[0044] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0045] According to an embodiment of the present invention, a water distribution component is provided, including: a water tank 1, a first water distribution structure 2, a second water distribution structure 3, and a driving structure 5.
