First, the operating principle in which the airflow (first airflow 30LU and second airflow 30RU) is sent out toward the front of the display surface 20b by the first outlet 15LU and the second outlet 15RU will be described.

When air is blown from the first outlet 15LU in the first direction from the first position on the left side of the housing 20a to the second position on the right side in a substantially parallel manner with respect to the display surface 20b, the blown air is Coanda. The first airflow 30LU along the display surface 20b due to the attraction phenomenon due to the effect (a phenomenon in which a negative pressure region is generated between the blown air and the display surface 20b and the blown air is attracted to the negative pressure region side). To form. Further, when air is blown from the second outlet 15RU in the second direction from the second position on the right side of the housing 20a toward the first position on the left side in a substantially parallel manner with respect to the display surface 20b, the blown air is blown out. , A second airflow 30RU is formed along the display surface 20b by the attraction phenomenon due to the Coanda effect.

It is the same as the operating principle in which the fifth airflow 30FU is sent toward. That is, the third airflow 30LL formed by the third outlet 15LL (see FIG. 1) and the fourth airflow 30RL formed by the fourth outlet 15RL collide with each other in the lower front region 30CL of the display surface 20b, and the display surface 20b By sending the airflow to the front of the display surface 20b, the sixth airflow 30FL is sent out from the display surface 20b to the front on the lower side of the display surface 20b.

As described above, in the blower device 10 having the display device 20 of the present embodiment, the fifth airflow 30FU is sent from above the display surface 20b toward the front by the first air outlet 15LU and the second air outlet 15RU, and the fifth airflow 30FU is sent. The sixth airflow 30FL is sent from below the display surface 20b toward the front by the third outlet 15LL and the fourth outlet 15RL. Therefore, the blower device 10 of the present embodiment can blow the airflow forward from two places on the display surface 20b. It should be noted that each airflow is blown out from the first outlet 15LU, the second outlet 15RU, the third outlet 15LL, and the fourth outlet 15RL so as to be substantially parallel to the display surface 20b.

FIG. 4 is a diagram schematically showing an example of controlling the amount of airflow blown from the first outlet 15LU, the second outlet 15RU, the third outlet 15LL, and the fourth outlet 15RL. FIG. 5 is a diagram schematically showing another example of controlling the amount of airflow blown from the first outlet 15LU, the second outlet 15RU, the third outlet 15LL, and the fourth outlet 15RL.

A control unit 70 is provided inside the blower 10. The control unit 70 includes a first airflow 30LU blown out from the first outlet 15LU, a second airflow 30RU blown out from the second outlet 15RU, and a third airflow 30LL blown out from the third outlet 15LL. It is an arithmetic unit that controls the amount of air blown from the fourth airflow outlet 15RL to the fourth airflow 30RL. The control unit 70 controls the air flow amount of each of the first airflow 30LU, the second airflow 30RU, the third airflow 30LL, and the fourth airflow 30RL, and causes the first airflow 30LU and the second airflow 30RU to collide with each other to cause the display surface 20b. The fifth airflow 30FU is generated from the front to the front, and the sixth airflow 30FL is generated from the display surface 20b to the front by colliding the third airflow 30LL and the fourth airflow 30RL.

Here, the airflow amount of the first airflow 30LU blown out from the first airflow outlet 15LU is determined by the airflow amount of the first blower 60LU that supplies air to the first airflow outlet 15LU. The airflow amount of the second airflow 30RU blown out from the second airflow outlet 15RU is determined by the airflow amount of the second airflow machine 60RU that supplies air to the second airflow outlet 15RU. The amount of airflow of the third airflow 30LL blown out from the third outlet 15LL is determined by the amount of airflow of the third blower 60LL that supplies air to the third outlet 15LL. The airflow amount of the fourth airflow 30RL blown out from the fourth airflow outlet 15RL is determined by the airflow amount of the fourth airflow machine 60RL that supplies air to the fourth airflow outlet 15RL.

Therefore, the control unit 70 controls the airflow amounts of the first blower 60LU, the second blower 60RU, the third blower 60LL, and the fourth blower 60RL, thereby controlling the first air outlet 15LU, the second air outlet 15RU, and the fourth air outlet. The amount of airflow of each airflow blown out from the third outlet 15LL and the fourth outlet 15RL is controlled.

A camera 80 is connected to the control unit 70. Further, a storage unit 90 is connected to the control unit 70. The storage unit 90 is provided inside the blower device 10 and stores the airflow transmission position and the air volume on the display surface 20b suitable for the image together with the image information displayed on the display device 20.

The control unit 70, for example, has the first blower 60LU, the second blower 60RU, the third blower 60LL, and the fourth blower 60RL, respectively, based on the airflow transmission position and the air volume on the display surface 20b stored in the storage unit 90. Determine the amount of airflow.

For example, as shown in FIG. 4, the storage unit 90 stores the airflow from the upper front area 30CU set in the upper right of the display surface 20b and the lower front area 30CL set in the lower left so as to send the airflow forward. If so, the control unit 70 is set so that each airflow (first airflow 30LU, second airflow 30RU) is blown out from the first outlet 15LU with a strong airflow and from the second outlet 15RU with a weak airflow. The amount of air blown by the first blower 60LU and the second blower 60RU is controlled. Further, the control unit 70 is a third blower so that each airflow (third airflow 30LL, fourth airflow 30RL) is blown out from the third outlet 15LL with a weak airflow and from the fourth outlet 15RL with a strong airflow. The air flow amount of 60LL and the fourth blower 60RL is controlled. As a result, the blower 10 can send each airflow (fifth airflow 30FU, sixth airflow 30FL) forward from the upper right region and the lower left region of the display surface 20b.

Further, as shown in FIG. 5, the storage unit 90 sends a strong airflow forward from the upper front area 30CU set in the upper right of the display surface 20b and a weak airflow from the lower front area 30CL set in the lower left. When stored in, the control unit 70 controls as follows. That is, each airflow (first airflow 30LU, second airflow 30LU, second) is generally stronger from the first outlet 15LU and the second outlet 15RU while weakening the airflow of the second outlet 15RU than the airflow from the first outlet 15LU. The control unit 70 controls the amount of air blown by the first blower 60LU and the second blower 60RU so that the airflow 30RU) is blown out. Further, while strengthening the air volume of the fourth air outlet 15RL than the air volume from the third outlet 15LL, each air flow (third airflow 30LL, fourth airflow 30LL, fourth airflow) is generally weak from the third outlet 15LL and the fourth outlet 15RL. The control unit 70 controls the amount of air blown by the third blower 60LL and the fourth blower 60RL so that the airflow (30RL) is blown out. As a result, the blower 10 can send a strong airflow (fifth airflow 30FU) from the upper right of the display surface 20b and a weak airflow (sixth airflow 30FL) from the lower left toward the front.

In this way, the control unit 70 determines the position at which the fifth airflow 30FU is generated on the display surface 20b and the sixth airflow 30FL on the display surface 20b based on the content of the image displayed on the display surface 20b of the display device 20. By controlling the position to be generated, each air flow can be sent forward from a plurality of portions of the display surface 20b.

Further, the control unit 70 grasps the positions of a plurality of viewers in front of the display device 20 and the age, gender, etc. of the viewers from the image of the area in front of the display device 20 captured by the camera 80. .. Then, the control unit 70 sends the airflow of the air volume that the viewers had to the two main viewers from the display surface 20b, so that the first blower 60LU, the second blower 60RU, and the first The amount of air blown by each of the third blower 60LL and the fourth blower 60RL is determined, and the position where the fifth airflow 30FU is generated on the display surface 20b and the position where the sixth airflow 30FL is generated on the display surface 20b are controlled. As a result, the control unit 70 sends an air flow forward from the plurality of portions of the display surface 20b toward the plurality of viewers in front of the display device 20 based on the image captured by the camera 80. be able to.

The control unit 70 determines the airflow amount of each of the first blower 60LU, the second blower 60RU, the third blower 60LL, and the fourth blower 60RL based on the airflow transmission position on the display surface 20b stored in the storage unit 90. Whether to determine these airflow amounts based on the image in front of the display device 20 captured by the camera 80 may be set by a switch (not shown) provided in the airflow device 10. Further, this setting may be performed by storing the setting information for each image information stored in the storage unit 90. Further, the control unit 70 may be configured to determine these airflow amounts only based on the airflow transmission position on the display surface 20b stored in the storage unit 90, or the display imaged by the camera 80. These airflows may be configured to be determined only based on the image in front of the device 20.

As described above, according to the blower device 10 according to the present embodiment, the first air outlet 15LU and the second air outlet 15RU send out the fifth airflow 30FU from above the display surface 20b toward the front, and the third airflow outlet 15LL. And the fourth air outlet 15RL sends out the sixth airflow 30FL from the lower side to the front side of the display surface 20b. Therefore, the airflow can be blown forward from the two locations on the display surface 20b.
