[0048] In order to enable those skilled in the art in the technical field to which the present application pertains to more clearly understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present application.
[0049] With the improvement of people's living standards, dishwashers have been widely used. During the use of dishwashers, hot water vapor is inevitably generated. The direct discharge of this part of the water vapor into the external environment is likely to cause indoor humidity, affect the cabinets in the home, and in some cases, even lead to slippery floors, thus affecting the user experience.
[0050] To overcome the above deficiencies, the dishwashers in related technologies are configured with a ventilation device composed of a breather and a vent. By extending the travel path of the water vapor in the ventilation device, the water vapor is liquefied to reduce the ejection amount of the water vapor, thereby reducing to a certain extent the indoor humidity caused by direct discharge, the impact on the cabinets in the home, and the technical problem of slippery floors.
[0051] However, during the actual operation of the dishwasher, there will still be some water vapor ejected, and the ejected water vapor will splash onto the outer shell of the dishwasher, especially the edge of the air outlet provided on the outer shell. After long-term accumulation, the water vapor in contact with the outer shell of the dishwasher will cause the outer shell to rust.
[0052] Based on the above technical problems, the present application provides a ventilation device and a dishwasher to avoid to a certain extent the phenomenon that the water vapor discharged from the ventilation device contacts the outer shell of the dishwasher and causes the outer shell to rust.
[0053] Figure 1 Shows a top view structural schematic diagram of the dishwasher in one or more embodiments of the present application.
