Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an aroma device capable of imparting aromatic components to odor-containing exhaust gas discharged outdoors through an exhaust duct.

[Conventional technology]

As is well known, in factories, warehouses, offices, etc., various odors are generated during the course of work and are emitted into the outdoor environment.

Because of this, there is a problem of odor pollution,
Several measures have been taken in the past. The most common method is to capture and separate malodorous substances or to make them odorless, such as washing methods, filtration methods, combustion methods, and catalytic oxidation methods. However, these methods require expensive equipment and contain a wide variety of odor components, so the reality is that they cannot be removed 100%.

Therefore, although it is conceivable that a masking method that is inexpensive and easy to handle may be used instead, conventional masking methods are implemented by placing deodorants and perfumes in the room.

[Problem that the invention attempts to solve]

According to the above-mentioned method of placing deodorants and perfumes indoors, since these are placed indoors, people in the room do not feel unpleasant odors, and this masking As long as the emitted air is released outside, people outside the room will not feel any unpleasant odor.

However, depending on the situation and conditions inside the room, it is not always possible to place deodorants etc. indoors, and from places where it is not possible to do so, exhaust gas containing unpleasant odors is released directly into the surrounding environment. .

Therefore, the purpose of the present invention is not to remove odors from outdoor exhaust, but rather to prevent people from sensing odors emitted into the outdoor environment, or to provide an effect that weakens them. The masking method was adopted based on the idea that it is better to prevent odor problems due to air pollution. To provide a device that can apply an aromatic agent to air when it is exhausted to the outside, thereby masking unpleasant odors at all times without being affected by indoor or outdoor conditions and situations. The purpose is to allow the release of Furthermore, by applying the fragrance at the exhaust duct equipment, it is possible to intensively and efficiently apply the fragrance to the exhaust gas.

[Means for solving the problems] In order to achieve the above object, the present invention has the following technical means. That is, to explain this using the reference numerals in the attached drawings that correspond to the embodiments, the present invention supplies air from the indoor room 1 to the outdoor 3 by driving the exhaust fan 5.
In the exhaust duct equipment for discharging to; a bypass pipe 6 is provided in the exhaust duct body 4;
A fragrance device for exhaust duct equipment, characterized in that a fragrance generating device 7 containing a built-in fragrance A for imparting aromatic components to the exhaust flow passing through the bypass pipe 6 is provided in the middle of the bypass pipe 6. It is.

[Effect]

With the above configuration, when the exhaust fan 5 is driven to send air from the indoor room 2 to the outdoor room 3, the exhaust flow also flows into the bypass pipe 6. At this time, a fragrance is imparted from the fragrance generator 7 to the exhaust flow passing through the bypass pipe 6, and even if there is an unpleasant odor in the air exhausted to the outside 3, the odor is masked.

〔Example〕

Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Example 1...See FIG. 1 In the figure, 1 indicates the wall of a building (factory, warehouse, office, general house, etc.), 2 indicates the interior, and 3 indicates the exterior.

Next, reference numeral 4 indicates a duct main body provided on the wall surface 1, and an exhaust fan 5 is provided within the pipe as usual.

The above is a general example of exhaust duct equipment, and this example is constructed as follows.

That is, a bypass pipe 6 is provided in the duct body 4. In the middle of this bypass pipe 6, an aroma generating device 7 as described below is provided. That is,
This device 7 consists of a main body 8 and an aromatic agent storage chamber 10 airtightly attached below the main body 8 via an O-ring 9. A primary flow path 11 is formed in the main body 8 in order to first introduce the exhaust gas supplied from the primary side bypass pipe 6a into the aromatic agent storage chamber 10, and then the exhaust gas is introduced into the aromatic agent storage chamber 10. A secondary flow path 12 is formed to discharge the exhausted exhaust gas to the secondary bypass pipe 6b, that is, to the outside 3.

Further, an aromatic agent outflow pipe 13 is connected to the secondary side flow path 12, and this terminal 14 is made to face above the liquid surface L of the liquid aromatic agent A.

Various types of liquid fragrances A can be considered, but as mentioned above, it is possible to use fragrances, so-called fragrances, and masking agents. can. Examples of fragrances or aromatic agents include natural fragrances (animal fragrances such as dill incense, beetroot incense, kairi incense, and ryuzen incense, plant roots, branches, leaves, flowers, flower buds, pericarp, seeds, etc.) It is possible to use synthetic fragrances (extracted fragrances and those obtained from pure synthetic raw materials such as tar-based or petrochemical products through synthetic reactions such as oxidation and condensation). can.

Examples of the above-mentioned vegetable natural fragrances include citronella oil, camphor oil, lemon oil, lemongrass oil, orange oil, peppermint oil, eucalyptus oil,
Examples include lavender oil, ocotia oil, pore rose oil, bergamot oil, spearmint oil, lime oil, petitgrain oil, clove oil, petipa oil, and ylang-ylang oil.

Furthermore, examples of synthetic fragrances include benzene-based synthetic fragrances, artificial ginger incense, and tenpen-based synthetic fragrances.

Further, as the above-mentioned masking agent, there is a so-called typically used pyroligneous vinegar solution to which the above-mentioned fragrance is added.

In any case, what is important is that the quality of the aroma needs to be selected optimally depending on the conditions of the usage environment, and those harmful to the human body are selectively removed.

Based on the above configuration, this operation will be explained. When the electric motor is driven and the exhaust fan 5 is driven, the indoor 2
The air inside is exhausted to the outside 3 via the exhaust duct body 4. Moreover, the exhaust gas is also exhausted through the bypass pipe 6.

In the above process, the exhaust gas passing through the bypass pipe 6 first enters the primary side 11 of the fragrance generator 7, and from there enters the liquid fragrance A storage chamber 10. The fragrance A is then exposed to the air stream, gradually evaporates under the pressure, and is mixed into the air stream.
Thereafter, the exhaust gas mixed with the aromatic component and added thereto passes through the secondary flow path 12 and is discharged into the use environment of the outdoor room 3. Therefore, even if an unpleasant odor occurs indoors, the odor will be masked by the aromatic components, so people in the surrounding environment outside will be able to avoid the discomfort caused by smelling this unpleasant odor. It will be opened,
In some cases, you can even enjoy the aromatic odor.

Furthermore, when the aromatic agent A in the aromatic agent storage chamber 10 is consumed, it is sufficient to fill the aromatic agent prepared in advance through an input port (not shown), and also to adjust the air flow rate and apply it to the aromatic agent. The ratio of the amounts of fragrance components can be adjusted by providing an orifice (not shown) in the fragrance outlet pipe B that can adjust the flow rate.
It may also be adjusted externally.

Example 2: See FIG. 2 This example is an example in which a large number of solid lumps of fragrance A are used.

That is, the liquid fragrances and aromatic substances described in Example 1 are combined into a solid lump using a solid binder as a binder, or the base material such as natural oil and fat is scented with the above-mentioned fragrance and the whole is made into a solid lump. Use the one that has been prepared. However, in this case, the binder or the base material itself is selected to be one that gradually evaporates under the pressure of compressed air.

In addition, the end 14 of the aromatic agent outflow pipe 13 connected to the primary flow path 11 is made to face the filling phase of the solid mass aromatic agent A. Other parts that are substantially the same as those in Example 1 are given the same reference numerals.

In this way, when the exhaust gas is introduced into the phase of the solid bulk fragrance A through the primary flow path 11, the solid bulk fragrance A is evaporated and vaporized.
Therefore, a fragrance component is imparted to the air introduced into the chamber, and this scented air is discharged into the surrounding environment via the fragrance outlet pipe 13 and the secondary flow path 12.

Therefore, even if there is an unpleasant odor coming from the room,
There is no risk of people in the vicinity sensing unpleasant odors in the exhaust gas that are released into the surrounding environment.

In this example, the fragrance is shown as a solid lump, but it may also be in the form of particles with a particle size that is not blown away by the compressed air flow.

[Effect of idea]

As detailed above, according to this invention, even if there is an unpleasant odor in the room, the odor can be masked by the aroma when it is discharged from the exhaust duct equipment to the outside.

Therefore, people living outdoors are not directly exposed to unpleasant odors, and in some cases, the fragrance can be emitted, making it possible to provide a better environment.

In particular, since the aromatic components are applied at the exhaust duct equipment, even if it is not possible to apply the aromatic components indoors due to the indoor conditions and circumstances, the aromatic agent can always be applied to the outside, and the exhaust duct Maskinda is highly efficient because the aromatic components can be applied in a concentrated manner.
