DEHUMIDIFIER

A dehumidifier includes a water tank, a machine body configured to be at least partially accommodated in the water tank in an idle state, and a position limiting structure including a stopper movably mounted at a side wall of the water tank. The stopper is configured to move between a first position and a second position. At the first position, the stopper is located on a movement path of the machine body moving toward inside of the water tank, to restrict the machine body from moving to the idle state. At the second position, the stopper avoids the movement path of the machine body moving toward the inside of the water tank, to allow the machine body to move to the idle state.
