  • an auxiliary blow part of a dehumidifier includes an auxiliary blow outlet 51d formed at one of airtight sides of the body 51 and a hose 410 connected to the auxiliary blow outlet 51d so as to be withdrawn outside the cabinet 20.
  • a coupling groove 411 is formed at an outer circumference of one end, and the coupling groove is coupled with the body 51.
  • a penetrating hole 29a is formed at one side of the cabinet confronting the auxiliary blow outlet 51d so as to draw out the hose 410 externally.
  • a switch plate 29b is formed near the penetrating hole 29a of the cabinet 20 so as to be revolvable.
  • the penetrating hole 29a is positioned at the same level of the auxiliary blow outlet 51d of the housing 40, whereby the hose 410 is drawn out in a horizontal direction.
  • the hose 410 is preferably a flexible hose so as to provide easy accommodation and withdrawal as well as a free variation of the withdrawal direction.
  • the present invention provides the dehumidifier having the main blow part of which blow direction of the dehumidified air is fixed and the auxiliary blow part of which blow direction is variable. Therefore, a user enables to supply a specific place intensively with the dehumidified air using the auxiliary blow part, thereby enabling to provide a variety of usages of the dehumidifier. For instance, when a laundry is dried, the dehumidified air is applied to the laundry intensively using the auxiliary blow part so as to maximize a dry effect.
