It has been confirmed that if the concentration ratio on the vertical axis is smaller than around 1/10 ⁸ , the fragrance cannot be sensed in the sensory test of fragrance intensity.
As shown in the figure, the concentration at point A is sufficient to feel a fragrance, whereas the concentration at point B after 2 minutes is 1 when the concentration at point A is 1, and the fragrance is not felt 1 concentration of less than /10 ⁸ .
Also from this, under the above conditions, the fragrance of the perfume sprayed toward the front of the space of the product display device is almost felt at a position (point B) 1 m away from the product display device 1 even immediately after the spraying. I know it won't. In other words, the product display device 1 according to the present invention keeps the fragrance within about 70 cm of the product display device and suppresses diffusion beyond that.
Moreover, according to the above results, it can be seen that the fragrance can be felt only in a limited narrow space in the vicinity immediately after the injection, and the fragrance does not spread to the surroundings even when the fragrance is constantly injected.

The inventor used the airflow simulation software to predict the concentrations of aromatic components at the points A and B by combining various airflow velocities. As a result, the airflow velocity from the air outlet 18 provided in the counter portion 11 of the counter unit 10 is 0.2 to 0.7 m/s, and the air velocity from the air inlet 38 behind the lower plate 36 of the ceiling unit 30 The surface speed of the suction air is about 0.5 m/s to 1.5 m/s. It has been confirmed that the airflow is preferably controlled in the product display device under the above conditions when the airflow is set to about 3.5 m/s.

Next, the inventor evaluated the fragrance intensity at points A, C and D during operation of the product display device of the present invention with a panel specializing in fragrance (n = 5). On the other hand, no fragrance was felt at point D, which was 1.5 m away, and it was found that the fragrance did not spread to the surroundings.

According to the product display device and the airflow control method for the product display device according to the present invention, the fragrance is delivered to people passing in front of the product display device to arouse interest in the product display device and It is possible to arouse the interest of the gathered customers by making the person standing in the room feel the fragrance only in a limited narrow space in the vicinity.
For example, even if a plurality of product display devices of the present invention are installed along with the flow of people, and different fragrances are emitted for each product display device, the fragrances from adjacent product display devices may be mixed. Instead, it is possible to introduce different fragrances to people who pass in front of the product display device or people who stop in front of the product display device for each product display device.

In addition, the product display device according to the present invention is not limited to the display and sales promotion of perfumes, cosmetics, etc., but also in restaurants and living spaces. It can also be applied for attracting customers, relaxing effects, and the like.
