Abstract

An air-blowing apparatus includes a main body and a fan. In the main body a blow-out region is formed. The fan is provided in the main body and sends air toward the blow-out region. The air-blowing apparatus blows out air from the blow-out region such that a ratio (Vmax/Vmin) of a maximum value Vmax of wind velocity to a minimum value Vmin of the wind velocity is 1 or more and 10 or less in a target virtual plane. The target virtual plane is a virtual plane that faces the blow-out region. As a result, comfort of a person exposed to the wind sent from the air-blowing apparatus is improved.

First claim

The invention claimed is:

1. An air-blowing apparatus comprising: a main body in which a blow-out region for blowing out air is formed; and a blowing member provided in the main body and configured to send the air toward the blow-out region, wherein
in a case in which
a rectangular virtual plane that faces the blow-out region, is positioned at a distance of 1 m from the blow-out region, and has a long side extending in a vertical direction and having a length of 60 cm and a short side extending in a right-to-left direction and having a length of 45 cm is set as a front virtual plane,
a rectangular virtual plane that faces the blow-out region, is positioned at a distance of 3 m from the blow-out region, and has a long side extending in the vertical direction and having a length of 180 cm and a short side extending in the right-to-left direction and having a length of 90 cm is set as a rear virtual plane,
a virtual space having a shape of a truncated square pyramid and including the front virtual plane and the rear virtual plane as base planes is set as a target virtual space, and
at least one of virtual planes included in the target virtual space and parallel to the front virtual plane is set as a target virtual plane,

air is blown out from the blow-out region such that a ratio (Vmax/Vmin) of a maximum value Vmax of wind velocity to a minimum value Vmin of the wind velocity is 1 or more and 10 or less in the target virtual plane, and
the apparatus further comprises a controller which controls operation of the blowing member, based on wind velocity data including a fluctuation pattern of wind velocity of wind blowing in an outdoor natural environment obtained in advance or in real time, such that a fluctuation pattern of a flow rate of the air blown out from the blow-out region is the fluctuation pattern of the wind velocity included in the wind velocity data.

2. The air-blowing apparatus of claim 1 , wherein
air is blown out from the blow-out region such that the ratio (Vmax/Vmin) of the maximum value Vmax of wind velocity to the minimum value Vmin of the wind velocity is 1 or more and 5 or less in the target virtual plane.

3. The air-blowing apparatus of claim 1 , wherein
air is blown out from the blow-out region such that the ratio (Vmax/Vmin) of the maximum value Vmax of wind velocity to the minimum value Vmin of the wind velocity is 1 or more and 2.5 or less in the target virtual plane.

4. The air-blowing apparatus of claim 1 , wherein
in a case in which a rectangular virtual plane that faces the blow-out region, is positioned at a distance of 2 m from the blow-out region, and has a long side extending in the vertical direction and having a length of 120 cm and a short side extending in the right-to-left direction and having a length of 67.5 cm is set as a middle virtual plane,
the target virtual plane is located in a portion of the target virtual space between the front virtual plane and the middle virtual plane.

5. The air-blowing apparatus of claim 1 , wherein
the target virtual plane is the rear virtual plane.

6. The air-blowing apparatus of claim 1 , wherein
the blowing member is a plurality of fans arranged so as to face the blow-out region.

7. The air-blowing apparatus of claim 1 , wherein
the main body includes a rectifying member configured to allow air to pass therethrough and provided on the entire blow-out region, and
the blowing member is a fan arranged upstream of the rectifying member.

8. An air conditioner comprising:
the air-blowing apparatus of claim 1 ; and
a heat exchanger which allows heat exchange of supply air to be sucked into the air-blowing apparatus with a thermal medium to adjust a temperature of the supply air.
