Description

Technical Field

[0001] The utility model relates to the technical field of washing equipment, in particular to a dishwasher. Background Art

[0002] Existing dishwashers dry dishes by heating water during the rinse cycle and radiating heat into the inner dish. The residual heat from the dishes evaporates the water on the surface. To expel the hot, humid air inside, an automatic door opening mechanism or a fan is used to vent it to the outside. However, this method suffers from low drying efficiency and high energy consumption for heating the water. Separate heating and drying devices and exhaust systems are also available in the prior art, but the exhaust system's actuators are slow to respond and consume a lot of energy.

[0003] In addition, some dishwashers place the fan in the base space. Since the fan is far away from the air inlet, the required air duct length increases. At the same time, the air duct has a large bend angle and many bends, which makes the air duct resistance large and the fan energy consumption required high. Utility Model Content
