Adjustment device, air duct structure, exhaust system, dishwasher, and method for controlling dishwasher

A method for controlling a dishwasher, wherein the dishwasher comprises:

• a shell;
• a tub;
• and
• an adjustment mechanism comprising an adjustment member having a pivoting end and a swinging end,
• wherein the shell comprises an exhaust channel, and a first air inlet and a second air inlet that are in communication with the exhaust channel,
• wherein the first air inlet being configured to introduce a first gas discharged from the tub, and the second air inlet being configured to introduce a second gas with humidity lower than humidity of the first gas, the method comprising:
• controlling the adjustment member to pivot to fully block the first air inlet;
• controlling the adjustment member to pivot to fully block the second air inlet;
• and
• controlling the adjustment member to pivot to partially block the first air inlet and the second air inlet to respectively adjust a flow rate of the first gas entering the exhaust channel through the first air inlet and a flow rate of the second gas entering the exhaust channel through the second air inlet to control a ratio of the first gas entering the exhaust channel to the second gas entering the exhaust channel,
• wherein controlling the adjustment member comprises:
• controlling, when the dishwasher is at a washing stage, the adjustment member to cover the first air inlet to decrease the flow rate of the first gas entering the exhaust channel;
• and
• controlling, when the dishwasher is at an exhaust stage, the adjustment member to expose each of the first air inlet and the second air inlet, to control the ratio of the first gas entering the exhaust channel to the second gas entering the exhaust channel.
