Abstract

PROBLEM TO BE SOLVED: To send an aroma to optionally selected other spaces and give the aroma to persons who enter the other spaces by providing a diffuser of an aroma delivered by a motor-driven fan and a sensor driving and controlling the motor upon detecting a person and forming changeably the arrangement relation of the sensor and the diffuser. SOLUTION: A battery-driven motor is housed in the driving circuit chamber 20 of a cylindrical motor case 11, and a fan 26 in a blast case 12 engaged relatively rotatably on the motor case 11 is rotated by the power. An aromatic tank 13 made up of a semispherical perfume storing cassette 41 and a cover 42 is arranged on the blast case 12. Air sucked from an air intake 47 formed on the top of the cover 42 and given an ascent when passing through a perfume (aromatic) 1 is discharged from a diffuser 37 by the rotation of the fan 26. A person detection sensor 29 is provided in the aromatic device 10 to turn on a motor 24 when detecting the approach of a person and drive the fan 26 and thereby generate an aroma.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a fragrance device.

[0002]

2. Description of the Related Art The fragrance device described in Japanese Utility Model Laid-Open Publication No. 4-851 and having a fragrance outlet blown by a fan driven by a motor and a sensor for detecting a person and driving the motor is disclosed in The outlet is fixed on the same side as the sensor, that is, on the front side of the fragrance. With this, when a person enters the front of the fragrance, the sensor detects this and drives the motor,
The aroma is blown out from the outlet to this person. Therefore, it was not possible to provide a sufficient aroma to a space different from the space into which the detected person has entered.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to distinguish a fragrance device from a space into which a detected person has entered.
An object of the present invention is to send a scent to another space arbitrarily selected in advance, and to provide a sufficient scent to others who enter the other space.

[0004]

SUMMARY OF THE INVENTION The present invention is an fragrance device comprising a fragrance outlet blown by a fan driven by a motor, and a sensor for detecting a person and driving the motor. The air outlet is provided on a side surface of a blower case, and the sensor is provided on a side surface of a motor case. The blower case and the motor case are relatively rotatably engaged with each other so that the arrangement relationship between the sensor and the air outlet can be changed. It is to become.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 3, the fragrance device 10 has a three-layer structure in which a motor case 11, a blower case 12, and a fragrance tank 13 are laminated.

[0006] The motor case 11 is formed of a cantilevered cylindrical body, and a bottom cover 21 is fitted to the bottom of a drive circuit chamber 20 formed by this. A battery 23 is inserted into a battery storage section 22 integrated with the bottom cover 21. It is stored. A motor 24 is mounted on the upper surface of the bottom cover 21, and a fan 26 is pressed into an output shaft 24 </ b> A of the motor 24. Battery storage section 22 provided on bottom cover 21
A drive circuit board 27 for the motor 24 is provided on the side surface of the motor case 11 with an operation lamp 28 for the motor 24 and a sensor 29 for detecting a person and driving the motor 24. 28 and a sensor window 29A corresponding to each of the sensor 29 are provided.

[0007] The blower case 12 has a claw 31 on the inner periphery of the lower end of the short cylindrical body, and this claw 31 is engaged with an annular groove 32 provided on the outer periphery of the top end of the motor case 11. Claw 3 with annular groove 32
1 slides, the blower case 12 becomes the motor case 11
Rotate relative to. The blower case 12 includes an upper partition plate 33 provided on the inner periphery of the upper end, and a substantially C provided on the lower surface of the upper partition plate 33.
And a character-shaped side partition plate 34. Thus, the blower case 12 forms a blower chamber 35 surrounded by the top surface of the motor case 11, the upper partition plate 33, and the side partition plate 34 in a state where the blower case 12 is engaged with the motor case 11. The above-mentioned fan 26 is arranged at the center, and the suction port 36 provided at the center of the upper partition plate 33 is arranged above the center of the fan 26,
An outlet 37 provided on a side surface of the blower case 12 corresponding to a substantially C-shaped end portion of the side partition plate 34 on an outer peripheral side of the side partition plate 34 is disposed.

The fragrance tank 13 includes a fragrance storage cassette 41.
And a cover 42. Perfume storage cassette 4
1 has a bottomed hemispherical shape and stores a fragrance 1 (fragrance). The fragrance storage cassette 41 has an entrance 43A opened at the top surface of the sphere, and a bottomed cylindrical portion 44 communicates with the center of the bottom surface.
An outlet 43B is opened in the side surface of the cylinder 4. The fragrance storage cassette 41 is placed on the support projection 38 on the upper surface of the upper partition plate 33 of the blower case 12, and the cylindrical portion 44 is disposed at the central suction port 36 of the upper partition plate 33. The cover 42 has a hemispherical cup shape and is engaged with and disengaged from the blower case 12. Cover 4
2 is provided with an air intake 47 on the top surface of the sphere, and the air intake passage 48 (the air intake passage 48 is
A portion extending from the bottom surface of the perfume storage cassette 41 to the upper surface of the upper partition plate 33 of the blower case 12 to the suction port 36 is formed.

When the sensor 29 detects a person, the motor 24 is turned on to drive the fan 26. When the fan 26 is driven, air flows from the air inlet 47 of the cover 42 through the air inlet passage 48 passing between the cover 42 and the fragrance storage cassette 41 from the suction port 36 to the blower chamber 35.
And the air intake 47 of the cover 42
Then, the fragrance in the fragrance storage cassette 41 is sucked into the blower chamber 35 from the suction port 36 by the fragrance intake passage 49 passing through the entrance 43A and the outlet 43B of the fragrance storage cassette 41. As a result, the air and the fragrance are mixed in the blower chamber 35 to generate fragrance, and are blown out from the outlet 37 on the side surface of the blower case 12.

The fragrance device 10 includes a sensor 29 and an outlet 37.
Can be changed. In particular,
As shown in FIGS. 4A and 4B, the outlet 37 is provided on the side surface of the blower case 12 and the sensor 29 is connected to the motor case 11.
As described above, in the fragrance device 10 provided on the side surface of the air conditioner, the blower case 12 and the motor case 11 are engaged so as to be relatively rotatable.

That is, in the fragrance device 10, the sensor 29
And the arrangement relationship of the outlet 37 can be changed. Therefore,
When the sensor 29 detects a person, the scent can be blown out to another space arbitrarily selected in advance, which is different from the space into which the detected person has entered, so before the other person arrives in this other space. The fragrance is blown out and the fragrance is deodorized in advance, and the fragrance can be sufficiently provided to others.

More specifically, as shown in FIG. 4 (C), a clog 5
When the fragrance 10 is installed on the top 4 and the resident 51 enters the sensing area A of the sensor 29, the fragrance 10 is activated and blows the fragrance from the outlet 37 into the entrance space where the fragrance is desired to be deodorized. Thereafter, the resident 51 opens the door 55 and the customer 52
When you meet, the scent is full. Customer 52
You don't have to smell the smell you care about. Since the relative direction between the sensor 29 and the outlet 37 can be arbitrarily selected and changed, it is possible to cope with various kinds of house layouts.

In the fragrance device 10, the arrangement relationship between the sensor 29 and the outlet 37 can be easily changed by engaging the blower case 12 and the motor case 11 so as to be rotatable relative to each other.

[0014]

As described above, according to the present invention, in the fragrance device, the fragrance is sent to another space arbitrarily selected in advance, which is different from the space into which the detected person has entered, and enters the other space. It can provide enough fragrance to others.
