Description

  The present invention relates to a blower that circulates air in a room such as an office, office, or store.

  As a conventional blower, there is one in which three blowers are attached to a connecting member that is attached to a ceiling or the like of a building. Of the three blowers, two blowers attached to both ends of the connecting member are attached to the connecting member so that the blowing direction can be changed horizontally with respect to the ceiling surface (for example, Patent Documents). 1).

Japanese Patent Laid-Open No. 2008-145099 (Summary)

  In the conventional blower as described above, although the horizontal blow can be arbitrarily set using three blowers, three blowers are required, which may increase the cost. Further, since the blower at both ends of the connecting member is fixed to the connecting member so as to be rotatable at the center, there is a possibility that the fan is inclined with respect to the ceiling surface due to vibration generated when the blower is driven.

  In the blower device that fixes the blower with the suspension bolt, it is possible to blow in the vertical direction. However, since the blower is secured with the suspension bolt, the horizontal direction cannot be changed. When changing the direction of the blower in the horizontal direction, it was necessary to remove the blower from the hanging bolts and put it down on the floor, which was troublesome.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a blower that can easily change the horizontal direction of the blower without removing the blower from the suspension bolt.

  The blower according to the present invention includes a rotation support base fixed by a suspension bolt, a rotation base fixed to the lower surface of the rotation support base in a horizontal direction with respect to the installation surface, and a lower surface of the rotation base. It has a plurality of fan motors for sucking indoor air and blowing it forward, and a blower that can change the blowing direction up and down.

  In the present invention, since the rotary support base fixed by the suspension bolt and the rotary base fixed to the lower surface of the rotary support base so as to be rotatable in the horizontal direction with respect to the installation surface, the direction of the blower is set. Can be changed with the turntable. For this reason, it is not necessary to remove the blower from the suspension bolt, and the work of changing the blower direction of the blower can be facilitated.
