Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a foreign matter prevention structure and a dishwasher. Background Art

[0002] The working stages of a dishwasher are generally divided into three stages. The first stage is the main wash, the second stage is the rinse, and the third stage is the drying. During the drying stage, the temperature in the dishwasher cavity will rise to a very high level, forming a large amount of water vapor. In order to dry the dishes, the water vapor in the cavity needs to be discharged or condensed. Generally, there are two types of drying methods, one is open-door exhaust, and the other is internal circulation condensation drying. Open-door drying has the best effect. During the drying stage, the motor will push the door open to exhaust the internal gas, but exhausting takes a certain amount of time.
