(Prior art) Conventionally, this type of air cleaning device has
As described in Publication No. 52 and shown in Figures 7 and 8, a fragrance-impregnated felt (C) is installed in the lower corner of a substantially rectangular casing (B) in which a fan (A) is installed. The fragrance case (D) is movably provided, and the notch (E) provided in the wall of the case (D) is opened and closed by moving the position of the fragrance case (D), thereby releasing and stopping the fragrance. There are known devices that can do this. still,
(F) is a knob for moving the fragrance case (D).

(Problems to be Solved by the Invention) However, according to the conventional example described above, the fragrance case (D)
By changing the position of the fragrance, the fragrance can be emitted or stopped. Therefore, the fragrance can be emitted only when the air purifying device is operated, but basically the above-mentioned Since the case (D) is operated manually, the fragrance is emitted continuously, and as a result, the occupants become accustomed to the smell of the fragrance and become desensitized to it. emanate,
There is a problem in that it is difficult to utilize the effect of fragrance release more effectively.

In other words, in general, the sensitivity of the human sense of smell changes greatly depending on the humidity, and as shown in Figure 5, when the humidity is high, the sense of smell becomes sensitive, but when the humidity is low, the sense of smell becomes insensitive, and it simply remains constant. Products that emit a fixed amount of fragrance intermittently every hour may give off a very strong odor to residents when the humidity is high, making them feel uncomfortable, or when the humidity is low. Even if the fragrance is diffused, there is almost no odor, and there is a problem that the effective use of the fragrance is not sufficient.

That is, the damper (72) is opened (and thereby the aroma passage (5) is opened, but the air purifying element (4) to which the aroma passage (5) bypasses has a large pressure loss during operation. occurs, and the exhaust port of the element (4) (
12) side is at a lower pressure than the intake port (11) side, so when the damper (72) is opened to open the passage (5), the pressure is lower on the intake port (11) side of the element (4). A part of the inflowing air bypasses the element (4) and passes through the suction side small hole (15) provided in the partition wall (13) to the aroma generating part (6) provided in the aroma passage (5). The air flows out along with the aroma through the exhaust side small hole (16) to the exhaust port (12) of the element (4), and the aroma is supplied into the room from the exhaust port (12).

However, in the present invention, as described above, the humidity sensor (
Since the indoor humidity is detected by the humidity sensor (8), and the opening degree of the damper (72) is adjusted based on this humidity, the amount of fragrance generation is controlled according to the humidity. ) constantly detects the indoor humidity, and the sensor (8
) The control section (9) controls the rotation angle of the stepping motor (7) based on the output of the stepping motor (7), and when the humidity is high, the opening degree of the damper (72) is decreased, and when the humidity is low, the opening degree of the damper (72) is decreased. By increasing the opening degree of the air outlet (72) and adjusting the amount of air passing through the aroma generator (6), the exhaust port (72) of the element (4) is removed from the aroma generator (6).
12) Since the amount of aroma supplied to the side can be adjusted, the odor reaction can always be kept constant without being affected by humidity, as shown in Figure 6. This means that you will never feel a sense of smell, and you will always be able to feel a pleasant fragrance, which will allow you to use the air freshener more effectively.

(Effects of the Invention) The present invention provides an air purifier in which a fan (3) and an air purifying element (4) are installed in a casing (1) having an intake port (11) and an exhaust port (12). 11 device, the casing (1) is provided with a fragrance passage (5) that short-circuits the intake port (11) side and the exhaust port (12) side of the air purifying element (4), and the aroma passage (5) ) is equipped with a fragrance generating part (6), and the exhaust port (1) is installed from the fragrance generating part (6).
2) An actuator section (7) is provided to adjust the amount of aroma sent out to the side, and a humidity sensor (8) is provided to detect indoor humidity, and the actuator section (7) A control unit (9
), in other words, the actuator section (7) is actuated based on the output of the humidity sensor (8) that detects the indoor humidity, so that air flow from the aroma generating section (6) to the exhaust port (12) side is provided. Since the amount of aroma sent out is adjusted, the aroma concentration will not be too high and cause an unpleasant odor to be felt, nor will the aroma concentration be so low that the user will not feel the aroma. Therefore, as shown in Figure 6, the odor reaction can be kept constant without being affected by humidity, and a pleasant aroma can be felt at all times, making it possible to use air fresheners effectively. .
