Further, the blower device 10 includes a fourth outlet 11R on the right side of the housing 20a at a position away from the display surface 20b from the second outlet 10R.

When the third airflow outlet 11L blows out the airflow from the left side of the housing 20a, the third airflow outlet 11L blows out the third airflow 31L in the direction away from the display surface 20b. When the fourth airflow outlet 11R blows out the airflow from the right side of the housing 20a, the fourth airflow outlet 11R blows out the fourth airflow 31R in the direction away from the display surface 20b.

As shown in FIG. 2, a first air conduction path 13L and a third air conduction path 14L are formed inside the left side of the housing 20a. Further, inside the right side of the housing 20a, a second air conduction path 13R and a fourth air conduction path 14R are formed.

Used. The camera 80 may be provided separately from the display device 20, or the camera 80 provided in the housing 20a of the display device 20 may be used.

Here, the operating principle of the blower 10 will be described with reference to FIG. When the first airflow 30L is blown out from the first outlet 10L in the first direction from the left side to the right side of the housing 20a substantially parallel to the display surface 20b, the blown out first airflow 30L is due to the Coanda effect. It flows along the display surface 20b due to an attraction phenomenon (a phenomenon in which a negative pressure region is generated between the first air flow 30L and the display surface 20b and the first air flow 30L is attracted to the negative pressure region side). Further, when the second airflow 30R is blown out from the second outlet 10R in the second direction from the right side to the left side of the housing 20a substantially parallel to the display surface 20b, the blown out second airflow 30R becomes the Coanda. It flows along the display surface 20b due to the effect attraction phenomenon.

Here, the first outlet 10L and the second outlet 10R face each other, and the first airflow 30L formed by the first outlet 10L and the second airflow 30R formed by the second outlet 10R are , Collide in the front region of the display surface 20b. Then, the collision first airflow 30L and the second airflow 30R are sent out as the fifth airflow 30F by having the display surface 20b as a wall and being pushed forward from the display surface 20b.

On the other hand, the third airflow 31L blown out from the third outlet 11L and the fourth airflow 31R blown out from the fourth outlet 11R surround the fifth airflow 30F sent forward from the display surface 20b. It will be in a state of being lost. It can be said that this is a state in which the fifth airflow 30F is sent out in the region sandwiched between the third airflow 31L and the fourth airflow 31R. That is, the third airflow 31L and the fourth airflow 31R function as an air curtain, and it is possible to prevent the fifth airflow 30F from diffusing outside the third airflow 31L and the fourth airflow 31R. Therefore, the fifth airflow 30F can be efficiently sent out from the display surface 20b toward the front by the airflow blown out from the first outlet 10L and the second outlet 10R.

Each airflow (first airflow 30L, second airflow 30R) is blown out from the first outlet 10L and the second outlet 10R so as to be substantially parallel to the display surface 20b. It suffices as long as the attraction phenomenon due to the Coanda effect can act, and the airflow blown out from the first outlet 10L and the second outlet 10R is slightly separated or approached from the direction parallel to the display surface 20b. However, it is included in the scope of the present invention.

A method of controlling the amount of air flow of the third airflow 31L and the fourth airflow 31R) will be described. FIG. 3 is a block diagram for controlling the amount of airflow blown from the first outlet 10L, the second outlet 10R, the third outlet 11L, and the fourth outlet 11R.

A control unit 70 is provided inside the blower 10. The control unit 70 has an airflow amount of the first airflow 30L blown out from the first outlet 10L, an airflow amount of the second airflow 30R blown out from the second airflow outlet 10R, and a third airflow blown out from the third airflow outlet 11L. It is an arithmetic unit that controls the amount of airflow of the airflow 31L and the amount of airflow of the fourth airflow 31R that is blown out from the fourth airflow outlet 11R.

Here, the air flow amount of the first airflow 30L blown out from the first air outlet 10L is determined by the air flow amount of the first air blower 40L that supplies air to the first air outlet 10L. The amount of air blown by the second airflow 30R blown out from the second air outlet 10R is determined by the amount of air blown by the second blower 40R that supplies air to the second air outlet 10R. The airflow amount of the third airflow 31L blown out from the third airflow outlet 11L is determined by the airflow amount of the third airflow machine 41L that supplies air to the third airflow outlet 11L. The amount of air blown by the fourth airflow 31R blown out from the fourth outlet 11R is determined by the amount of air blown by the fourth blower 41R that supplies air to the fourth outlet 11R.

Therefore, the control unit 70 controls the airflow amount of each of the first blower 40L, the second blower 40R, the third blower 41L, and the fourth blower 41R, so that the first blower outlet 10L, the second blower outlet 10R, and the third blower outlet 10R The amount of airflow of each airflow blown out from the outlet 11L and the fourth outlet 11R 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 content of the image together with the image information displayed on the display device 20.

The control unit 70 has, for example, the first blower 40L and the second blower based on the airflow transmission position and the air volume on the display surface 20b, which is stored in the storage unit 90 and is suitable for the content of the image displayed on the display surface 20b. The amount of air blown by each of the 40R, the third blower 41L, and the fourth blower 41R is determined.

For example, when the storage unit 90 is stored so as to send the fifth air flow 30F forward from a predetermined position on the display surface 20b with a predetermined air flow, the display surface 20b starts with the predetermined air volume from the predetermined position. The control unit 70 determines the amount of airflow of the first airflow 30L blown out from the first airflow outlet 10L and the second airflow 30R blown out from the second airflow outlet 10R so that the fifth airflow 30F is sent forward. Calculate the amount of airflow. Then, based on the calculated airflow amount of the first airflow 30L blown out from the first airflow outlet 10L and the airflow amount of the second airflow 30R blown out from the second airflow outlet 10R, the control unit 70 sets the first blower 40L. , Controls the amount of air blown by the second blower 40R.

Further, the control unit 70 appropriately surrounds the fifth airflow 30F that is sent forward from the predetermined position, and the airflow amount and the third airflow 31L of the third airflow 31L that is blown out from the third airflow outlet 11L. The amount of airflow of the fourth airflow 31R blown out from the four outlets 11R is calculated. Then, based on the calculated airflow amount of the third airflow 31L blown out from the third airflow outlet 11L and the airflow amount of the fourth airflow 31R blown out from the fourth airflow outlet 11R, the control unit 70 sets the third airflow machine 41L. , Controls the amount of air blown by the fourth blower 41R.

In this way, the control unit 70 controls the position on the display surface 20b where the fifth air flow 30F is generated, based on the content of the image displayed on the display surface 20b of the display device 20.

In addition, the control unit 70 grasps the position of the viewer in front of the display device 20, the age, gender, and the like of the viewer 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 first blower 40L and the second blower 40R so as to send the fifth airflow 30F of the air volume that the viewer had to the main viewer from the display surface 20b. Determine the air volume. Further, the control unit 70 determines the amount of air blown by the third blower 41L and the fourth blower 41R, which are necessary to appropriately surround the fifth airflow 30F to be sent out. Then, the first blower 40L, the second blower 40R, the third blower 41L, and the fourth blower 41R are controlled so as to obtain the determined blower amount.

In this way, the control unit 70 controls the position on the display surface 20b where the fifth air flow 30F is generated, based on the image captured by the camera 80.

As described above, the control unit 70 controls the amount of each airflow blown out from the first airflow outlet 10L, the second airflow outlet 10R, the third airflow outlet 11L, and the fourth airflow outlet 11R, and controls the third airflow. In the region sandwiched between the 31L and the fourth airflow 31R, the first airflow 30L and the second airflow 30R collide with each other to generate a fifth airflow 30F from the display surface 20b toward the front. Therefore, the blower 10 can send out the fifth airflow 30F from the predetermined position on the display surface 20b with a predetermined air flow, and at the same time, the third airflow 31L and the fourth airflow 31R send out the fifth airflow forward from the display surface 20b. The five airflows 30F can be reliably surrounded. Therefore, the airflow blown out from the first outlet 10L and the second outlet 10R can efficiently send out the fifth airflow 30F from the display surface 20b toward the front.

The control unit 70 determines the amount of air blown by each of the first blower 40L, the second blower 40R, the third blower 41L, and the fourth blower 41R based on the airflow sending position on the display surface 20b stored in the storage unit 90. Whether to determine these airflow amounts based on the image of the area 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 of the area in front of the device 20.

As described above, according to the blower device 10 according to the present embodiment, the first airflow 30L blown out from the first outlet 10L and the second airflow 30R blown out from the second outlet 10R are directed forward from the display surface 20b. The fifth airflow 30F is sent out. Further, the third airflow 31L blown out from the third outlet 11L and the fourth airflow 31R blown out from the fourth outlet 11R surrounded the fifth airflow 30F sent forward from the display surface 20b. It becomes a state. That is, in the region sandwiched between the third airflow 31L and the fourth airflow 31R, the fifth airflow 30F is sent forward from the display surface 20b. Therefore, it is possible to prevent the fifth airflow 30F from diffusing outside the third airflow 31L and the fourth airflow 31R, so that the airflow blown out from the first airflow outlet 10L and the second airflow outlet 10R (first airflow 30L, The second airflow 30R) can efficiently send out the fifth airflow 30F from the display surface 20b toward the front.
