WIPO Patent Application WO/2017/131203
Kind Code:
A1
Abstract:
Provided is a work vehicle in which adhered dust is removed prior to deterioration in the efficiency of an air conditioner device, whereby the efficiency of the air conditioner device is satisfactorily maintained. In order to achieve this, a combine harvester (1), which is a work vehicle, is provided with: a cabin (20) in which a driving unit (201) is installed; an air conditioner device for the driving unit (201); a rotating fan (342), which rotates forward to supply air for heat-exchanging to a capacitor of the air conditioner device; an external air intake (209) for taking in air for heat-exchanging; and a fan control unit for controlling the rotating fan (342). During the operation of the air conditioner device, the fan control unit controls the rotating fan (342) so as to inversely rotate every predetermined period and so that the inverse rotation is faster than the forward rotation, and thereby efficiently blows away dust adhered to the external air inlet (209), etc.
