The invention provides a dish washer, which not only can reduce condensed water at an air outlet, but also can reduce noise at the air outlet.

In one embodiment of the present invention, as shown in fig. 1, 2 and 6, the dishwasher includes: the air duct structure 100, the first fan 200 and the guide piece 300, wherein the air duct structure 100 comprises a main air duct 110 and an air outlet communicated with the liner 1 of the dish washer; the first fan 200 is disposed between the air outlet and the inlet of the main air duct 110, and the first fan 200 is configured to exhaust the hot and humid air in the liner 1 into the main air duct 110; the flow guiding member 300 has an inlet end and an outlet end, the inlet end is connected to the outlet of the main air duct 110, and the outlet end is arranged in a flaring structure along the air outlet direction.

Because the dish washer provided by the application is provided with the guide piece 300 at the outlet of the main air duct 110, the guide piece 300 can prolong the distance between the air flow in the main air duct 110 and the outside atmosphere, so that the temperature of the wet and hot air flow in the main air duct 110 can be slowly reduced in the outflow process, but not suddenly reduced, and condensed water generated at the outlet of the main air duct 110 can be reduced; in addition, the inlet end of the air guiding member 300 is connected to the outlet of the main air duct 110, and the outlet end of the air guiding member 300 is arranged in a flared structure along the air outlet direction, so that when the air flows out of the main air duct 110 via the air guiding member 300, the cross-sectional area of the air guiding member 300 is gradually increased in the air outlet direction, and the noise in the air outlet air flowing out process can be reduced.

Further, referring to fig. 2, in order to further reduce wind resistance in the air flow out process, in an embodiment of the present application, an inner wall surface of the flow guiding member 300 includes a first flow guiding surface and a second flow guiding surface disposed between the inlet end and the outlet end and disposed opposite to each other, and the first flow guiding surface and/or the second flow guiding surface are disposed in an arc shape. Specifically, in this embodiment, the first guide surface and the second guide surface are both arc-shaped, and because the first guide surface and the second guide surface are both arc-shaped, wind resistance in the airflow outflow process can be reduced, so that only weak noise or no noise can be generated when the air-out airflow flows out.

Specifically, the guide rib 310 is disposed in the middle of the first guide surface and the second guide surface, and the distance between the guide rib 310 and the first guide surface, and the distance between the guide rib 310 and the second guide surface are gradually widened along the air outlet direction. Since the guide rib 310 has a guiding effect on the air-out airflow, the air-out airflow can be prevented from being directly blown out, so that the flowing distance of the air-out airflow can be prolonged, and the probability of generating condensed water at the outlet of the main air duct 110 can be reduced.

Further, referring to fig. 2, the structure of the flow guiding rib 310 will be described in detail, where the flow guiding rib 310 includes a first section and a second section that are sequentially disposed in the airflow direction, and a connection portion between the first section and the second section is in a circular arc shape. Because the junction of first section and second section is convex setting, consequently can avoid the air-out air current to produce the vortex when flowing to the junction of first section and second section, and then can avoid producing great air-out noise.

In a preferred manner, in this embodiment, the first section is arc-shaped, and the first section is located at the middle of the inlet end, the second section is linear, and the second section is located at the middle of the outlet end.
