Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is suitable for use in containers having a relatively narrow space, such as indoors of buildings, automobiles, trains, etc., especially lockers for storing clothing, small items, etc. It stores and holds volatile chemicals such as deodorizers to eliminate odors and air fresheners to emit fragrances.
The present invention relates to a volatile chemical dispersion device capable of dispersing deodorized or scented gas into a room, a vehicle interior space, or a container interior space.

[Prior Art] Conventionally, devices for dissipating volatile chemicals of this type include:
Packaging bags, boxes, or bottles of solid deodorizers, air fresheners, etc. that are sold in sealed packaging are opened and opened at the time of use, and left unopened in any location to allow indoor or car air to come into contact with the deodorizer. There are known products that are purified and brought into contact with the aromatic agent to emit a fragrance. However, there is a problem in that a satisfactory deodorizing and aromatic effect cannot be expected by simply placing the packaging bag or the like in an arbitrary location.

As a deodorizing/fragrance device that solves this problem, there is also known a structure in which a blowing mechanism such as a fan is disposed inside the device to discharge deodorizing/fragrance gas to the outside. According to such a device, a wide range of space can be quickly filled with deodorizing and aromatic gas.

[Problems to be Solved by the Invention] However, in the above-described deodorizing/fragrance device, the discharge port is usually provided opening in the side wall of the housing, and the fan is installed in the gas passage in the housing.
Since an axial type fan is provided that rotates approximately perpendicular to the bottom wall, the housing must be made considerably thick to allow the fan to rotate. In this case, it is conceivable to reduce the radius of the fan, but in such a case, there is a problem that the blowing force decreases.

Therefore, installing such a large device in items with relatively small internal spaces, such as shoe racks and clothing lockers, considerably reduces the space that should originally be used for shoes or clothes. There was a problem.

In view of the above-mentioned conventional circumstances, the present invention has been developed as a thin and compact device, which can obtain the same blowing force as the conventional device, and can be installed in a relatively small space such as a clothing locker. The purpose of the present invention is to provide a device for dispersing volatile chemicals suitable for

[Means for Solving the Problems J] The volatile chemical dissipation device of the present invention includes a housing having an outside air intake and a discharge port formed at appropriate locations on an outer wall, and an outlet having an opening formed at one end. , a spiral casing disposed within the housing, having a gas inlet formed by opening a part of the ceiling surface, and having the outlet communicated with the discharge port; an air blowing mechanism disposed in the housing, which is rotatably disposed substantially horizontally with the bottom of the housing, and is configured to direct gas that has come into contact with a volatile agent disposed at an appropriate position within the housing through the gas inlet; an impeller that sucks in the gas from the axial direction, sends it out radially outward, and dissipates the gas to the outside of the device through the outflow port and the discharge port; and a gap between the impeller and the bottom surface of the housing to rotate the impeller. It is characterized by having a flat drive motor disposed therein, and a blowing mechanism consisting of the following.

[Example] Hereinafter, a more detailed explanation will be given based on an example of the present invention shown in the drawings.

In the figure, 1 is a volatile chemical dissipation device according to the present invention, and 2 is a housing made of plastic, metal, etc. and formed into a substantially rectangular shape as an outer box of the dispersion device 1. It consists of a lid 2b that fits into the main body 2a and can be opened and closed. in this case,
It goes without saying that the hinge structure may allow the lid to be opened and closed freely. 1.3 is an outside air intake formed at an arbitrary location on the upper wall 2c of the lid 2b, and 4 is an outlet port formed at an arbitrary location on the side wall of the housing body 2a. It is. Here, the outside air intake section 3 is not limited to the one provided on the earthen wall 2c of the lid 2b as in the present embodiment;
Alternatively, the gap formed between the main body 2a and the lid 2b may be used as the outside air intake section.

Reference numeral 5 denotes a holding part for placing and storing a volatile chemical 11 such as a deodorizer or an aromatic agent, and is formed of a box-shaped member with an open top fixed on the bottom wall part 2d of the main body 2a. It is possible to surround and hold drugs, etc. Note that this holding part 5
The external shape is not limited in any way. Moreover, even if such a holding part 5 is not provided, a deodorizer or the like may be attached to an arbitrary space within the housing 2. Furthermore, when replacing the deodorizer 11 etc., the M2b may be removed from the housing main body 2a and replaced, or a pull-out mechanism may be provided so that the holding part 5 can be taken in and out from the side wall of the main body 2a. . Furthermore, the bottom wall portion 2d of the main body 2a
It is also possible to freely open and close a part of the clay wall part 2C of the lid 2b, and to make it possible to replace the deodorizer 11 and the like.

6 is a fan and constitutes a ventilation mechanism. This fan 6 consists of an impeller 61 and a drive motor 62. A part of the ceiling surface is opened, and the open part serves as a gas inflow lower b, and an outflow lower a is formed at one end, and the outflow lower a communicates with the discharge port 4 of the housing main body 2a. It is disposed within a substantially spiral-shaped casing 7 to which it is connected. That is, the fan 6 is a so-called radial fan that accelerates the fluid sucked in from the axial direction through the inflow lower b and sends it radially outward of the impeller 61.

As shown in FIG. 3, the impeller 61 is formed with a partially protruding blade portion 61b around the impeller 61. Further, as shown in FIG. 2, a rotating shaft 61a protruding substantially perpendicularly to the bottom wall 2d of the housing 2 is connected to the drive motor 6.
The impeller 61 is supported by a support shaft 62b erected on the base 62c of the rotor 2, and is rotatable substantially horizontally with respect to the bottom wall portion 2d.

The drive motor 62 is not particularly limited as long as it is of a flat type that can be disposed in the gap between the back side recess of the impeller 61 and the bottom wall 2d of the housing body 2a. In this embodiment, the support shaft 62b, the coil portion 62a wound around an iron core protruding around the support shaft 62b, and the coil portion 62
A brushless DC motor consisting of an annular permanent magnet 62d, which is disposed in close contact with the recessed part on the back side of the impeller 61, opposite to a, and magnetized with different magnetic poles depending on the part, and a Hall element (not shown). has been set up. This results in
When the magnetic pole generated in the coil portion 62b changes, the permanent magnet 6
2d repulses this, causing the impeller 61 to rotate.

Reference numeral 8 denotes a circuit board mounted with electronic components arranged to send electrical signals to the drive motor 62, and is connected to the main switch 9. Note that 10 is a lead wire for connecting an external power source.

Further, the circuit board 8 is provided with a timer circuit (not shown). Reference numeral 12 denotes an optical sensor that detects a change in the amount of light from a reflecting plate (not shown) provided on the object to be detected and sends an ON/OFF signal to an electric circuit. Therefore, if the optical sensor 12 and the timer circuit are electrically connected and the main switch 9 is turned on, the optical sensor 12
This structure allows the fan 6 to be operated according to the time set in the timer circuit based on the ON signal from the timer circuit.

The volatile chemical dispersion device 1 having such a configuration operates as follows. First, the lid 2b of the dispersion device 1 of this embodiment is removed and the deodorizer 11 is stored in the holding part 5. Then, it is installed in a container equipped with an opening/closing door (not shown), for example, a clothing locker. In this case, within the thickness of the top plate or partition plate of the locker, so as not to obstruct the storage of clothes, etc.
It is preferable that the parts other than the discharge port 4, main switch 8, optical sensor 12, etc. be embedded. On the other hand, the reflector is fixed to any position on the opening/closing door (.Also, the main switch 9 is kept in the ON state.

Now, when the opening/closing door is closed and the light sensor 12 detects that the light intensity reaches a predetermined level when the light emitting device 1 of this embodiment is approached,
Current flows in an electrical circuit.

As a result, the drive motor 62 of the fan 6 is driven, and the impeller 61 is rotated according to the time set in the timer circuit.

On the other hand, the air taken in from the outside air intake part 3 is the deodorizer 11.
After being brought into contact with the gas, the gas is sucked into the casing 7 from the gas inlet lower b of the casing 7 as shown by the broken line arrow in FIG. Then, it is sent out to the outside in the radial direction of the impeller 61 (in the direction of the solid arrow in FIG. 1), and is sent to the discharge port 4 of the housing 2.
It is discharged to the outside of the device 1 from the outflow lower C of the casing 7, which is communicated with.

Note that the discharged deodorizing and aromatic gas may be directly dissipated into a container such as a shoe rack, or when used in a large room, it may be further diffused by an arbitrary ventilation mechanism (not shown). It is also possible to do so.

[Effects of the Invention] According to the volatile chemical dissipation device of the present invention, the fan constituting the ventilation mechanism is of a so-called radial type, and the drive motor is thin enough to be disposed between the impeller and the bottom wall of the housing. Because the device uses a conventional device, the device itself can be made extremely thin and compact compared to conventional devices. Furthermore, despite its thinness, the amount of air blown does not decrease compared to conventional ones.

Therefore, it can be embedded, for example, in the top plate of a clothing locker, etc., and is suitable for use in a container having a relatively narrow space.

Furthermore, if a light sensor and a timer circuit are installed, they can be activated only when the door is closed, allowing for efficient use of deodorizers, etc., without wasting them. I can do it.
