Dish washing machine and air suction device thereof

The invention discloses a dish washing machine and an air suction device thereof. The air suction device of the dish washing machine comprises a shell and a driving mechanism. The shell is provided with an air inlet, an air outlet and a condensation air flue. The air inlet and the air outlet are communicated through the condensation air flue. The condensation air flue is circuitous. The driving mechanism is installed on the shell. The driving mechanism comprises an air supply piece located inside the shell. The driving mechanism is used for driving the air supply piece to rotate so as to enable airflow in an inner container of the dish washing machine to be guided into the condensation air flue through the air inlet and exhausted from the air outlet. According to the air suction device of the dish washing machine, air in the inner container can be guided into the condensation air flue by the driving mechanism through the air supply piece and exhausted out of the dish washing machine from the air outlet.
