[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier mounted on a vehicle such as an automobile, and more particularly to an air purifier having an aroma function.

[0002]

2. Description of the Related Art A conventional air purifier of this type has a schematic structure as shown in FIG. That is, 2
Reference numeral 0 denotes a housing that forms an air flow path 21 through which clean air A generated by a driving force of a fan (not shown) flows. The air flow path 21 has a bypass path 24 having an inlet 22 and an outlet 23. Is formed. In the bypass passage 24, a solenoid valve 25 and the fragrance container 2 to which the fragrance is sprayed by the operation of the solenoid valve 25 are provided.
The fragrance is ejected by operating the solenoid valve 25 at an appropriate time, and is discharged together with the clean air A flowing through the air flow path 21 into, for example, a vehicle interior.

[0003]

However, in such a conventional fragrance ejecting air purifier, since the fragrance is of a single type, any fragrance can be replaced with the same air according to the taste. There was a problem that it could not be discharged from the purifier, it was not possible to selectively use various kinds of fragrances according to the tastes of the people and further according to the environment, and the fragrance efficiency was low.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and is provided inside an air purifier.
While interior a plurality of kinds of fragrances and allowed having a control circuit for selectively spraying these fragrances, in automatic, fragrances suitable for preference and the environment by operating the control circuit is released To provide an air purifier.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in FIG. 1, but the basic structure of the air purifier is not changed from that of the conventional example.

That is, in this embodiment, a plurality of types of fragrance containers 1 and 2 are provided in a bypass passage 24 shown in the conventional example.
2,3,4,5, these fragrance containers 1,2,2
Electromagnetic valves 1-1, 2- corresponding to 3, 4, 5
1, 3-1, 4-1 and 5-1 are provided. Reference numeral 6 denotes a control circuit for selectively driving the above-described electromagnetic valves. The control circuit 6 receives signals from an air conditioner 7, a smoke sensor 8, and a manual switch group 9. In this embodiment, the manual switch group 9 includes a cigarette switch 10, a dozing switch 11, a traffic jam switch 12, a preference switch 13, a power switch 14,
An automatic mode switch 15 is provided. In this embodiment, a floral scent in the container 1, a mint scent in the container 2, a lemon scent in the container 3, a forest scent in the container 4, and a daffodil scent in the container 5. It is assumed that the fragrance is filled.

The above is the configuration of the present embodiment. Next, its operation will be described.

When the air purifier is driven, when the power switch is turned on and the automatic mode switch 15 is operated, the drive signal from the air conditioner 7 installed in the room, for example, when the air conditioner 7 is cooled, is particularly refreshed. The electromagnetic valve 2-1 for scenting the scent of mint that gives a sense of sensation operates. When the air conditioner 7 is heated, the solenoid valve 1-1 for scenting a floral scent that gives a sense of warmth operates.

When the smoke sensor 8 installed in the room detects that the smoke is full, the smoke sensor 8
The electromagnetic valve 3-1 that aromas lemon scent suitable for alleviating the smoke by the signal from the device operates.

The above is the case of the automatic fragrance. If the automatic mode switch 15 is turned off and the manual switches 10 to 13 are selectively operated, various fragrances are selectively discharged in accordance with the switch. That is, when the cigarette switch 10 is operated during driving of the car, the scent of lemon is released in the same manner as described above, and when the dozing switch 11 is operated when the user feels drowsy, the scent of mint is scented and the drowsiness is eliminated. You. Also, when there is a traffic jam, the traffic jam switch 1
By operating 2, the scent of the forest is released from the container 4, and the irritability of the mood can be calmed down. By operating the taste switch 13, for example, the scent of daffodils according to the taste is released from the container 5.

Therefore, according to this embodiment, an appropriate fragrance is released in accordance with the indoor environment according to the operation of the air conditioner or a signal from the smoke sensor. The agent can be selectively perfumed, and the perfume effect can be further enhanced.

[0012]

As described above, according to the present invention, the air flow path 20 through which the air flow A generated by the driving force of the fan passes,
A having an inflow port 22 and an outflow port 23 communicating with the flow path 20
A bypass passage 24 and a plurality of bypass passages installed in the bypass passage 24;
Number of fragrance containers 1 to 5 and the plurality of fragrance containers 1 to 5
A fragrance is spouted from each opposed fragrance container 1 to 5
A plurality of solenoid valves 1-1 to 5-1;
A control circuit 6 for selectively operating 1 to 5-1;
A cabin that supplies a control signal to the circuit 6 according to the situation in the cabin
Since the air purifier is composed of the internal state output means 7 and 8 , various fragrances are provided according to the state of the vehicle interior.
Selective automatic spraying for driver or passenger
The fragrance effect (comfort, drowsiness, mood, etc.)
Can be performed quickly and without interfering with driving operation.
Wear.
