Abstract

PROBLEM TO BE SOLVED: To improve the fast-acting property and persistence of a fragrance and a malodor reducing effect by filling a perfume carrier group carrying a perfume in the ventilation passage of a container. SOLUTION: This aromatic unit 1 is partitioned into a container installation chamber 12 and a blower installation chamber 13 by a partition plate 11 with ventilation holes. A container 21 filled with a perfume carrier group 20 is installed in the container installation chamber 12. A motor 25 and a fan 26 are installed in the blower installation chamber 13. An air intake port 30 and an air blowout port 31 are provided. The perfume carrier group 20 may be filled in the container installation chamber 12 as it is or in an air-permeable bag without using the container 21. When the container installation chamber 12 is used as a container, the numerical aperture of the air blowout port 31 is set to about 20% or below. The fan 26 is driven to send air to the perfume carrier group 20, and the air containing the perfume is discharged into a room from the air blowout port 31. The fast-acting property and persistence of a fragrance and a malodor reducing effect can be improved.

2. Description of the Related Art A conventionally known aroma vessel filled with a fragrance in a unglazed container has a problem in terms of sustainability because the fragrance is constantly volatilized. Japanese Patent Application Laid-Open No. Hei 10-85313 discloses a type of fragrance device in which the presence of a person is sensed by a sensor, and an electric fan is driven to thereby volatilize fragrance. However, since this fragrance has a high degree of sealing of the container from the viewpoint of preventing unnecessary volatilization of the fragrance, it is inevitable that the pressure loss increases and the air volume decreases,
As a result, there is a problem that the aroma intensity is insufficient.
