In the present embodiment, a grille 7a is provided at the air outlet 7, and the cleaning unit 12 is formed to be rotatable. Other parts are the same as those in the first embodiment.

  The grille 7a is formed in a lattice shape and can prevent entry of foreign matters such as metal pins and clips from the air outlet 7. The cleaning part 12 can be inserted through the opening 7b at a predetermined position partitioned by the grill 7a. FIG. 11 is a side cross-sectional view showing a state in which the lid 10 is closed when the air outlet is closed. The cleaning part 12 inserted into the opening part 7 b of the outlet 7 is guided by the grill 7 a and the flexible part 12 b slides on the partition panel 22. And the flexible part 12b contacts the discharge electrode 18a, and the cover part 10 is closed. Since the flexible portion 12b accurately passes over the discharge electrode 18a by the guide of the grill 7a, foreign matters on the discharge electrode 18a can be reliably removed.

Thereby, the cover part 10 removed from the blower outlet 7 can be carried easily.

  According to this embodiment, the same effect as that of the first embodiment can be obtained. Moreover, since the extended part 12b of the cleaning part 12 is formed so as to be foldable with respect to the cover part 10, the removed cover part 10 can be easily carried.

  Moreover, since the cleaning part 12 is guided by the grill 7a arranged in the blower outlet 7, the flexible part 12b accurately passes over the discharge electrode 18a by the guide of the grill 7a. Therefore, the foreign matter on the discharge electrode 18a can be reliably removed and the foreign matter can be prevented from entering from the outlet 7.

  It should be noted that it is more desirable that the lid portion 10 cannot be attached to the air outlet 7 in a state where the cleaning portion 12 is folded. Thereby, the discharge electrode 18a can be reliably cleaned. For example, it is possible to restrict the mounting of the lid portion 10 by forming the folded cleaning portion 12 so as to contact the grill 7a.

  In the first and second embodiments, only the negative ions may be emitted by the ion generator 18. Thereby, a user's relaxation effect can be acquired.
