no. 1 Embodiment approach

[0045] First, the basic structure of a vehicle fragrance apparatus to which the present invention is applied will be described. Aroma devices for vehicles such as figure 1 As shown, it has: the air-conditioning fan 2 of the vehicle air-conditioning device (vehicle air-conditioning) 1; the main ventilation path 5, which runs from the air-conditioning fan 2 to the air-conditioning outlet 4 opened in the compartment 3; the branch ventilation path 6, which flows from the The main ventilation passage 5 branches off in the middle, and merges with the main ventilation passage 5 again;

[0046] A fragrance valve 9 for blowing the fragrance of the fragrance 7 into the vehicle interior 3 through the air-conditioning outlet 4 is provided on the downstream side of the fragrance container 8 . Opening and closing of the aroma valve 9 controls the blowing of the aroma of the fragrance agent 7 into the vehicle interior 3 or the stopping of the blowing of the aroma. A fragrance fan 10 is pro...

no. 2 Embodiment approach

[0072] Figure 11 It is a graph showing the change with time of the average concentration of aroma in the vehicle interior in the second embodiment. In the second embodiment, the concentration of the aroma blown out is lower than that of the first embodiment, and as Figure 11 As shown, the stop time from the end of the intermittent blowing cycle to the start of the next intermittent blowing cycle is shortened to a time T6 shorter than the stop time T3 in the first embodiment. Let the maximum concentration at the end of one cycle of the intermittent blowing cycle be C2'. Figure 11 In the figure, the solid line indicates the case of the second embodiment, and the dotted line indicates the case of the first embodiment.

[0073] In this way, compared with the first embodiment, since the average concentration of the aroma in the vehicle interior 3 can be suppressed lower, and the interval between each intermittent blowing cycle can be shortened to blow out the aroma, therefore, i...

no. 3 Embodiment approach

[0075] Figure 12 It is a graph showing the change with time of the average concentration of aroma in the vehicle interior in the third embodiment. In the third embodiment, the concentration of the blown aroma is made higher than that in the first embodiment, and the number of blowing out per cycle of the intermittent blowing cycle is reduced to a number less than that in the first embodiment. Figure 12 In , the solid line represents the case of the third embodiment, and the dotted line represents the case of the first embodiment.

[0076] As shown in the third embodiment, since the number of blows per cycle of the intermittent blowing cycle is reduced, the introduction amount of the aroma of the aromatic agent 7 into the vehicle interior 3 is reduced, so that it is possible to suppress the amount of blowing in one cycle of the intermittent blowing cycle. The increase of the average concentration of aroma in the car at the moment when the cycle ends.

[0077] In addition, b...

Abstract

Provided is a fragrance device for vehicle with an aim to restrain an olfactory adaptation of an occupant, to continuously provide the occupant for a long time with changes in sensory intensity of smell caused by intermittent smell emission, and to provide the occupant for a long time with a relaxation effect due to a smell, the fragrance device for vehicle includes: a fragrance holder holding a fragrance; a blowing means for blowing air to the fragrance holder to blow a smell of the fragrance into a vehicle cabin; and a fragrance blowing control means for sequentially repeating the repeating of a predetermined cycle of blowing a smell of the fragrance and a pause predetermined times by intermittently blowing the smell at each cycle, and then the providing of a stop time for stopping the blowing out of the smell of the fragrance for a predetermined time period.

Description

technical field [0001] The invention relates to a fragrance device for vehicles. Background technique [0002] Japanese Unexamined Patent Application Publication No. 2-60821 discloses a vehicle aroma device that intermittently sprays aroma by opening and closing an on-off valve of an aroma container containing an aroma agent, thereby delaying occupant's sensitivity to aroma. Contents of the invention [0003] However, in the above-mentioned fragrance device for vehicles, since the concentration of the emitted fragrance is high, and the pause time of the intermittent injection is relatively short relative to the amount of ventilation in the vehicle interior, the fragrance will fill the vehicle with the passage of time. indoor. As a result, the effect of the intermittent injection cannot be obtained, and the occupant's sense of smell has already adapted, so the above-mentioned fragrance device for a vehicle cannot give occupants a sense of relaxation and stability for a lon...
