Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an aroma generating device applied to an air cleaner or the like.

[Background technology]

BACKGROUND ART Conventionally, an air cleaner equipped with a fragrance generating means as shown in FIGS. 1 and 2 has been proposed. In the figure, 1 is a fan casing with a spiral curve that houses a multi-blade fan 2;
It is housed in an exterior case 3. A part of the exterior case 3 is also used as the fan casing 1. The fan 2 is attached to the output shaft of a motor 4 fixed to an exterior case 3. The fan casing 1 has a bellmouth-shaped suction ``15'' on the front surface and a discharge port 6 on the top surface, and a dust removal filter 8 and a A deodorizing filter 9 is inserted.The discharge port 6 is provided with a discharge port grid of 1°.11
is a switch.

Reference numeral 12 denotes an aromatic member, which is attached to the discharge port grid 10. The aromatic member 12 is a block-shaped (rod-shaped, disk-shaped, etc.) fragrance material (diluted with a volatile solvent such as alcohol).
Impregnate the impregnated body 13 such as ferret molded into
L is provided in a part of the air flow path, and when the air cleaner is in operation, it is released into the room together with the clean air that has been filtered by the filter.

However, the Glock-like impregnated body 13 with a relatively small surface area
Because it contains fragrance ingredients, it is difficult to effectively scent the room unless you use a fragrance diluted with a highly volatile alcohol-based solvent, and the fragrance has a short lifespan due to its high volatility. On the other hand, since such a block-shaped aroma member 12 is disposed in a part of the air passage, it is not possible to use a very large one because of an increase in ventilation resistance. As a result of these factors, fragrance generation is strong at an early stage, its fragrance life is relatively short, and it becomes necessary to replace it frequently.

[Object of the Invention] An object of the present invention is to provide a fragrance generating device that can produce a pleasant fragrance over a long period of time.

[Disclosure of the invention]

The aroma generating device of the present invention includes an aroma member made of porous ceramic holding an aroma agent, and this aroma member is disposed in an air passage of a casing.

Embodiment An embodiment in which the present invention is applied to an air cleaner is shown in FIGS. 3 and 4. Note that the same parts as in the examples of FIGS. 1 and 2 are designated by the same reference numerals, and their explanation will be omitted. That is, in this aroma generating device IT, aroma members 15 are provided thinly on the entire inner surface of the peripheral wall of the fan casing 1, on the front surface of each blade piece 2a of the fan 2, and on the discharge port lattice 10. The aromatic member 15 is a porous ceramic powder or small particles impregnated with an aromatic agent dissolved in a solvent. Porous serimink retains the fragrance on its pore surface due to its surface adsorption power.

While the operating fan 2 is stopped, the air is still on the surface of the porous ceramic on which the aromatic agent is applied, so that the fragrance is hardly released into the air. When the fan 2 is operated, the air on the surface of the porous ceramic of the aromatic member 15 flows,
The aromatic agent evaporates into the air from the porous ceramic surface and is widely diffused into the room together with the air purified by the filter 8.9.

It works in this way, but unlike a simple impregnating agent like felt that contains a fragrance diluted with a highly volatile solvent, the fragrance is adsorbed and held in a porous ceramic called an industrial adsorbent. Because of this, the fragrance continues for a long time. In addition, since the aroma member 15 is disposed on the surface of the ventilation path, the generation of aroma is promoted when the fan 2 is in operation, and the generation of aroma is slowed down when the fan 2 is stopped, resulting in aroma generation #! The sustainability of performance improves. Furthermore, the aromatic member 15 has 11
Since the fan 2 is provided in a single shape, an increase in ventilation resistance can be almost ignored when the fan 2 is operated.

In addition, many air purifiers generally have a power switch.
However, because of the above-mentioned configuration, the fragrance generation is automatically switched between strong and weak in conjunction with the strength of the air purifier.

5 and 6 show other embodiments. In this example, an aromatic member 16 made of granular porous ceramic impregnated with a liquid aromatic agent (5) and formed into a sheet shape is provided on a part of the inner surface of the peripheral wall of the fan casing 1. It is desirable that the volatilization surface of the aromatic member 16 be flush with the inner surface of the polar cuff casing 1. A shielding surface member 17 for suppressing volatilization is provided on the opposite side of the aromatic member 16 from the volatilization surface.

A conduit 19 is connected to the aromatic member 16 for introducing a liquid aromatic agent from an aromatic agent container 18 provided outside the fan casing 1 . 20 is a conduit housing pipe. conduit 1
9 introduces the liquid fragrance 21 by capillary action,
It is made of water-absorbent string-like heartwood. Air freshener container 18
The structure is such that liquid fragrance can be replenished from the outside.

In addition, the liquid air freshener 21 includes not only those intended for so-called fragrance, but also essential oils extracted from natural plants such as trees, etc.
It also includes those that have bactericidal and antibacterial effects.

When configured in this way, the liquid aromatic agent 21 is volatilized into the air from the aromatic member 16, and the aromatic agent volume is increased one after another! 11
8 through a conduit 19Th, a liquid aromatic agent 21 is supplied to the aromatic member 1.
Therefore, by replenishing the fragrance container 18 once, a fragrance generating function can be obtained for a long time. Its (ltM is the same as in the first embodiment.

FIGS. 7 and 8 show still other embodiments.

In this example, the fan 2' is of a horizontal type, and an aromatic member 23 is provided at the center of the fan 2'. The aromatic member 23 is
An aromatic agent 25 is housed in an aromatic agent container 24 whose outer peripheral wall is made of porous ceramic.

The fragrance 25 may be in liquid form and impregnated into the sponge-like body, or may be in the form of grease or solid (such as soap). The fragrance container 24 is provided with a lid that can be opened and closed, and when the fragrance 25 runs out, it is possible to replenish the fragrance. Fan 2' motor 4
is housed in a motor cover 26 that protrudes downward from the exterior case 3.

The suction lower' is provided on the upper side surface. 27 is a leg.

In this configuration, fan 2' IE! At the time of one rotation, the centrifugal force causes the aromatic components of the aromatic agent 25 of the aromatic member 23 to be dispersed into the air, and are diffused into the room along with the wind. Therefore, aromatic clean air is effectively supplied. In addition, since the aromatic member 23 is placed in the center of the fan 2',
The fragrance container 24 is of considerable size and can hold a relatively large amount of fragrance. Therefore, it can withstand long-term use. When the fan 2' does not rotate, centrifugal force does not work, and volatilization of the aromatic agent 25 is suppressed. Since the outer peripheral wall of the aromatic agent container 24 is made of porous ceramic, only a small amount of the aromatic agent will volatilize unless centrifugal force is applied. Aromatic components are diffused to the outer periphery. Therefore, the aromatic agent is used effectively and retains its aromatic function over a long period of time.

〔Effect of the invention〕

The fragrance generating device of this invention has the advantage of being able to emit a pleasant fragrance for a long period of time.
