Description

  The present invention relates to an air conditioner such as an air purifier, a dehumidifier, and a humidifier.

  An air purifier, which is one of air conditioners, sucks indoor air and cleans it, and then circulates and supplies the clean air into the room again. The dehumidifier sucks indoor air, removes moisture contained in the air sucked inside, and circulates and supplies the dehumidified dry air to the room again. Further, the humidifier humidifies indoor air by dissipating the supplied water to the outside.

  For example, Patent Documents 1 and 2 describe an air cleaner that sucks indoor air from a suction port using a fan and discharges the air into the room.

  However, as shown in FIG. 8, in any of the air purifiers 51 described in any of the patent documents, if the fan 52 is made small in order to reduce the size, the fan 52 and the suction port 53 formed in a substantially vertical direction are interposed. Due to the size of the motor 54, the distance between the fan 52 and the motor 54 can be secured only by S11, and there is a problem that a sufficient air volume cannot be obtained.
