Description

  The present invention relates to an air purification attachment and an air purifier. More specifically, the present invention relates to an air purification attachment and an air purifier using chlorine dioxide gas.

Various germs such as viruses are present in the atmosphere, and when such a virus (for example, a new influenza virus) or the like is inhaled by a person, there is a possibility that the virus will infect the virus and become sick.
In view of this, a technique has been developed in which a virus or the like is removed from air sucked by a person by sterilizing the virus or the like present in the air, thereby preventing the person from being infected with the virus or the like. For example, in Patent Document 1, an environmental purifier has been developed in which air sucked into a device is brought into contact with chlorine dioxide gas to sterilize, and the sterilized air is supplied to the outside of the device.
Chlorine dioxide is extremely unstable and difficult to handle. Therefore, the environmental purifier of Patent Document 1 adopts a configuration in which chlorine dioxide gas is generated from a stabilized chlorine dioxide solution in which chlorine dioxide is dissolved in an alkaline solution, and the generated chlorine dioxide gas is sucked into the air. Deodorizing and sterilizing by contact.

Such an environmental purifier can reduce viruses and the like in the air, and thus is effective in preventing a person from getting sick by being infected with a virus or the like.
However, in order to employ a configuration in which chlorine dioxide gas is generated from a chlorine dioxide solution in the main body, it is necessary to provide a complicated structure. Moreover, since chlorine dioxide gas is generated from the chlorine dioxide solution in the environmental purifier, the container for containing the chlorine dioxide solution and the gas generation mechanism are increased in size, resulting in a problem that the apparatus is also increased in size. . Further, since the chlorine dioxide solution is alkaline, there is a safety problem.

Next, an embodiment of the present invention will be described with reference to the drawings.
First, the air purification attachment 20 of this embodiment is demonstrated.
The air purification attachment 20 of the present embodiment is an accessory for use by being attached to the air purification device 30 shown in FIG. 1, and can purify the air C discharged from the blowing section 32 with a simple structure. It has the feature in doing so.

(Explanation of the device)
First, before describing the air purification attachment 20, a device to which the air purification attachment 20 is attached will be described.
The device for attaching the air purification attachment 20 has a function of sucking air into the main body of the device and discharging the sucked air out of the main body of the device from the blowing portion.
For example, the air purification device 30 includes a suction portion 31 for sucking air outside the device main body into the inside, a purification means for purifying the intake air (not shown) in the main body, and the purified air A blowout part 32 for discharging outside is provided. The blowing portion 32 is provided on the upper surface and the side surface of the main body portion. The blowing part 32 provided on the upper surface of the main body is hereinafter simply referred to as the upper face blowing part 32b, and the blowing part 32 provided on the side surface of the main body is hereinafter simply referred to as the side blowing part 32a.

In addition, the blowing part 32 comes to discharge | emit the direction where the air Ca discharged | emitted from the side blowing part 32a provided in the side surface of the main-body part of the air purification apparatus 30 flows slightly upwards with respect to the horizontal. It is preferable. In this case, the chlorine dioxide gas A described later can be distributed far.
For example, if a plate-like wing is formed on a member that covers the side blowing portion 32a, the direction of the discharged air is adjusted by adjusting the member, and the discharged air is slightly above the horizontal. If a rotary fan is provided in the main body, such a state can be formed by arranging the rotary fan.

  In the above-described example, the air purification device 30 is shown as a device to which the air purification attachment 20 is attached. However, the device is not limited to this device, and a device having the above-described function, for example, a device used as an air conditioning system. Air conditioners used in automobiles and automobiles can also be employed.

(Description of the air purification attachment 20)
As shown in FIG. 2, the air purification attachment 20 (hereinafter simply referred to as an attachment 20) of the present embodiment is configured to include a container 21 that can contain chlorine dioxide powder M therein.

  The chlorine dioxide powder M is obtained by making chlorine dioxide into powder or granules. The chlorine dioxide powder M is adjusted so that it reacts with moisture in the air and vaporizes to generate chlorine dioxide gas, and a commercially available product can be used.

(Description of container 21)
The accommodating body 21 has an accommodating space 21h in which the chlorine dioxide powder M can be accommodated together with air. For example, as shown in FIG. 2, a hollow rectangular box can be adopted as the container 21. However, the container 21 is not particularly limited as long as the container 21 has a housing space 21 h for housing the chlorine dioxide powder M therein.

  As shown in FIG. 2, the housing 21 is provided with a ventilation portion 21 a that communicates between the housing space 21 h and the outside on the upper surface of the housing 21 formed in a rectangular box shape. When the ventilation portion 21a contains at least the chlorine dioxide powder M in the housing 21, the chlorine dioxide powder A generated by the reaction of the chlorine dioxide powder M with moisture in the air can be supplied to the outside. Is formed.

  In the above example, the container 21 has a rectangular cross section when the ventilation portion 21a is the upper surface. However, the container 21 is not limited to this shape, and a triangular shape or the like is also employed. be able to.

  Since it is the above structure, if the chlorine dioxide powder M is accommodated in the accommodating space 21h in the accommodating body 21, the chlorine dioxide gas M reacts with the moisture contained in the air in the accommodating space 21h, so that the chlorine dioxide gas A is generated. appear. Then, the generated chlorine dioxide gas A can be supplied to the outside of the container 21 from the ventilation portion 21 a provided in the container 21.

(Description of the mounting position of the air purification attachment 20)
The attachment 20 of the present embodiment configured as described above is used by being attached to the apparatus as described above.

Specifically, as shown in FIG. 1A, the attachment 20 is attached below the side surface blowing portion 32a so that the ventilation portion 21a of the container 21 of the attachment 20 is located.
When the container 21 is arranged in this way, the chlorine dioxide gas A generated by the reaction of the chlorine dioxide powder M in the container 21 with moisture in the air is supplied to the outside of the container 21 from the ventilation portion 21a. The chlorine dioxide gas A supplied to the outside of the container 21 rises almost vertically from the ventilation portion 21a to a certain height (dotted arrow in the vicinity of the ventilation portion 21a in FIG. 1B).
On the other hand, out of the air C discharged from the air blowing portion 32 of the air purification device 30, the air Ca discharged from the side blowing portion 32a is discharged slightly upward relative to the horizontal (FIG. 1B ) Solid line thick arrow on the side of the main body).
Then, the direction in which the chlorine dioxide gas A supplied from the ventilation portion 21a of the container 21 flows (hereinafter simply referred to as the chlorine dioxide gas A flow direction) and the direction in which the air Ca discharged from the side blowing portion 32a flows (hereinafter, referred to as the chlorine dioxide gas A flow direction). Therefore, the chlorine dioxide gas A supplied from the ventilation part 21a can be reliably put on the flow of the air Ca discharged from the side blowing part 32a.

As described above, if the attachment 20 is attached to the air purification device 30, both flow directions do not intersect. For example, the flow direction of chlorine dioxide gas A and the direction in which the air discharged from the air blowing portion 32 flows (hereinafter, In this case, the chlorine dioxide gas A can be distributed more efficiently than when the flow directions are substantially vertical, in other words, both flow directions are substantially parallel.
Then, although it is not complete, the virus etc. which exist in the air which contacted the chlorine dioxide gas A distributed can be disinfected to some extent.
As a result, when a person breathes, the air that has been sterilized and purified to some extent by the virus is sucked, so that the person can be prevented from being infected by the virus.

  Moreover, when the attachment 20 of the present embodiment is used, when adopting a configuration in which air is sucked into the apparatus and the air is purified in the apparatus, for example, chlorine dioxide gas is generated from a chlorine dioxide solution in the apparatus. The air can be purified with a simpler structure as compared with the case of adopting the configuration.

  Note that the air in contact with the distributed chlorine dioxide gas A includes air C other than the discharged air C in addition to the air C discharged from the blowing section 32. The air C discharged from the blowing part 32 is, for example, the air Ca discharged from the side blowing part 32a, and the air other than the discharged air C is, for example, the air Ca discharged from the side blowing part 32a. Air that mixes with and contacts.

  Further, in the above-described example, the case where one attachment 20 is attached to the lower side of the side blowing portion 32a is used, but the number of attachments 20 that are attached to the main body of the air purification device 30 is plural. May be. For example, in addition to the above-described example, the attachment 20 may be further attached in the vicinity of the upper surface blowing portion 32b. Then, in addition to the effect by the chlorine dioxide gas A supplied from the attachment 20 attached below the side surface blowing portion 32a, the upper surface blowing portion 32b by the chlorine dioxide gas A supplied from the attachment 20 attached in the vicinity of the upper surface blowing portion 32b. It is possible to purify air Cb and the like discharged from the air.

(Other examples of mounting positions)
In an apparatus having an intake port for sucking air on the front surface, such as the air purification apparatus 30 described above, the attachment 20 may be attached to the back surface of the apparatus (see FIG. 5B).

In this case, since the intake port is provided on the front surface of the device, the flow of air sucked into the intake port (hereinafter simply referred to as the intake air flow) when the device is in use is near the front and side of the intake port. Flows from the air to the air intake.
In addition, when the suction capability of an intake fan or the like for sucking air provided in the apparatus is high, the air in the vicinity of the back surface of the apparatus flows toward the intake port on the front surface (black indicated by the symbol D in FIG. 5A). A thick arrow) is formed.
That is, when the suction capability of an intake fan or the like is high, the air behind the back of the device flows toward the intake port provided on the front of the device so as to be wound along the side of the device from the back of the back.

Since such a flow is formed, if the container 21 is disposed on the back surface of the apparatus, the chlorine dioxide gas A supplied from the container 21 to the outside rides on the intake air flow and rises toward the front surface of the apparatus. Flowing.
That is, the supplied chlorine dioxide gas A can be raised obliquely forward with respect to the vertical.
Then, the flow direction of the chlorine dioxide gas A (see the dotted arrow indicated by the symbol A in FIG. 5C) can intersect the upper surface discharge flow direction (see the white arrow of the symbol Cb in FIG. 5C). .
If it does so, the chlorine dioxide gas A supplied from the ventilation rear part 21a can be reliably put on the flow of the air discharged | emitted from the exhaust port provided in the apparatus upper surface (refer FIG. 5 (B) and (C)).

  As described above, in an apparatus having an intake port for sucking air on the front surface, if the attachment 20 is attached to the rear surface of the apparatus, the flow direction does not intersect. Compared with the case where the attachment 20 is attached to the back surface of the apparatus, the chlorine dioxide gas A can be distributed efficiently.

In addition, you may attach to the back surface of an apparatus so that the ventilation part 21a of the container 21 of the attachment 20 may be located above the upper end edge of the inlet port of the apparatus front surface.
If the container 21 is attached at such a position, the ventilation portion 21a is positioned above the upper end edge of the intake port, so that the chlorine dioxide gas A supplied upward from the ventilation portion 21a is taken into the intake air. It can be made difficult to be sucked into the mouth.

  In addition, you may arrange | position so that the upper end edge of the ventilation part 21a may be the same position as the blower outlet provided in the upper surface of the apparatus, ie, the upper end edge of the ventilation part 21a, and the said blower outlet. In this case, it is possible to prevent the chlorine dioxide gas A supplied from the ventilation portion 21a from coming into direct contact with the member on the back of the apparatus.

(Description of package MP)
Further, as shown in FIG. 3, the chlorine dioxide powder M is not directly supplied into the container 21, but the package MP in which the chlorine dioxide powder M is enclosed in the bag is supplied into the container 21. Good.
In this case, the structure of the container 21 that contains the chlorine dioxide powder M can be simplified as compared with the case where the chlorine dioxide powder M is directly contained in the container 21. Moreover, since the chlorine dioxide powder M does not spill from the container 21, and it is not necessary to touch the chlorine dioxide powder M directly, it can be used safely.
For example, a commercially available product (for example, Asptrol (CSR-1.05 10 g Sacht) manufactured by BASF) or the like can be used for the package MP, but it goes without saying that the product is limited to this product. For example, any material can be used as long as the material of the bag can absorb moisture and supply the moisture to the internal chlorine dioxide powder M and allow the chlorine dioxide gas A to permeate.
Moreover, you may employ | adopt what covered the said marketed product with the bag which has the said function for the further safety | security. That is, since the chlorine dioxide powder M is packaged in a double bag, even if a person with weak skin touches the package, it is preferable to reduce dermatitis and the like.

(Description of the container 21 for housing the package MP)
Further, if the container 21 is formed as follows, even if the ventilation portion 21a is formed by a plurality of through holes as shown in FIG. It is preferable that the package MP can be easily replaced.

  Specifically, as shown in FIG. 3B, the container 21 includes a fixed portion 22 and a movable portion 23 so that the movable portion 23 can swing with respect to the fixed portion 22. It is connected to. In addition, since the storage space 21h formed between both the fixed portion 22 and the movable portion 23 is formed so that its volume is slightly larger than the volume of the packaging body MP, supply and replacement of the packaging body MP. Can be made easier.

Hereinafter, individual members will be described.
The fixing portion 22 is formed to include a back plate 22a attached to the main body of the air supply device and a pair of side walls 22b erected on both side edges of the back plate 22a.

  The lower end of the movable portion 23 is connected to the lower end of the back plate 22a in the fixed portion 22 by a connecting portion 24, and the movable portion 23 is swung so as to approach and separate from the back plate 22a of the fixed portion 22 with the connecting portion 24 at the lower end serving as a fulcrum. The fixed portion 22 is movably attached. That is, the movable part 23 covers the opening between the pair of side walls 22b in a state where the movable part 23 is close to the back plate 22a of the fixed part 22, in other words, in a state where the movable part 23 is closed. The housing space 21h is formed in a shape that can form the space.

  Then, if the movable part 23 is swung away from the back plate 22a of the fixed part 22 with the connecting part 24 provided at the lower end of the fixed part 22 as a fulcrum, a large opening is formed between them. be able to. For this reason, since the packaging body MP can be taken in and out of the accommodation space 21h through the opening, the packaging body MP is supplied from the ventilation portion 21a of the accommodation body 21 to the accommodation space 21h in the accommodation body 21 as compared with the case where the packaging body MP is supplied. The supply and replacement of the body MP can be facilitated.

In addition, the connection part 24 will not be specifically limited if it is the structure which can connect the movable part 23 to the lower end of the fixing | fixed part 22 so that rocking | fluctuation is possible. For example, a configuration in which a through hole communicating with the lower end portion of the side wall 22b of the fixed portion 22 and the lower end portion of the side edge portion of the movable portion 23 is provided and a bolt or the like is inserted into the through hole may be employed. Alternatively, a configuration may be employed in which a concave portion facing inward is formed at the lower end portion of the side wall 22b of the fixed portion 22 and a corresponding convex portion is formed at the lower end portion of the side end portion of the movable portion 23. In this case, as shown in FIG. 2 and FIG. 3 (A), the movable portion 23 is formed such that the side edge sandwiches and covers the pair of side walls 22b of the fixed portion 22, It is preferable that the movable portion 23 can be swingably connected to the lower end of the fixed portion 22 without employing a member.
Further, the fixing means 25 may be provided so that the movable portion 23 and the fixed portion 22 are not separated in a state where the movable portion 23 is close to the back plate 22 a of the fixed portion 22. As shown in FIG. 3A, the fixing means 25 is provided with a convex portion 25a facing inward at the upper portion of the side edge of the movable portion 23, and the concave portion 25b corresponding to the convex portion is formed on the side wall 22b of the fixing portion 22. You may employ | adopt the structure provided in. In this case, it is preferable because the movable part 23 and the fixed part 22 can be prevented from being separated by vibration or the like.

(Other examples of air purification attachments)
Before describing another example of the air purification attachment, the relationship between chlorine dioxide gas and a member of an apparatus for attaching the air purification attachment will be described.
When chlorine dioxide gas contacts a synthetic resin member for a long time, the synthetic resin in the contacted portion may be altered (for example, cured).
In order to solve such a problem, if the container 41 having the configuration described below is employed, the supplied chlorine dioxide gas A can be prevented from coming into contact with members such as the back surface of the apparatus. In particular, there is an advantage that the chlorine dioxide gas A immediately after being supplied with a high concentration in the air can be efficiently prevented from coming into contact with these members.

(Description of the air purification attachment 40)
As shown in FIG. 4, another air purification attachment 40 of the present embodiment is configured to include a container 41 that can store chlorine dioxide powder M, and an upper surface portion of the container 41 provided with a ventilation part 41 a. This is different from the container 21 described above in that a protruding portion 42a protruding upward from the base plate 42 is formed on the back plate 42.
In addition, about the same content as the container 21 mentioned above, description is omitted.

(Description of container 41)
The container 41 is composed of a back plate 42 and a housing part 43. The accommodating portion 43 has a lower end edge and a side end edge connected to the back plate 42, and an inner surface thereof is formed to face the inner surface of the back plate 42, and a space is formed therebetween. . That is, an accommodation space 41 h for accommodating the chlorine dioxide powder M is formed between the accommodation portion 43 and the back plate 42.
In addition, a ventilation portion 41 a that communicates between the accommodation space 41 h and the outside is provided on the upper portion of the accommodation body 41.
Moreover, the back plate 42 is formed with a protruding portion 42a that protrudes upward from the upper surface portion of the container 41 provided with the ventilation portion 41a.

Since it is the above structure, if it arrange | positions so that the upper end edge of the backplate 42 of the container 41 of the air purification | cleaning attachment 40 may correspond substantially with the upper end edge of the back surface of an apparatus (refer FIG.5 (B)), it will attach. The above effects can be obtained efficiently.
Because, when arranged as described above, the air around the apparatus forms the above-described intake flow, so that the chlorine dioxide gas A supplied from the vent 41a to the outside of the container 41 is along the upper back of the apparatus. It flows while rising obliquely forward with respect to the vertical (see the dotted arrow in FIG. 5C).
However, since the protruding portion 42a exists between the ventilation portion 41a and the back surface of the apparatus, it is possible to prevent the supplied chlorine dioxide gas A from coming into direct contact with members on the back surface of the apparatus.
That is, the chlorine dioxide gas A supplied to the outside of the container 41 from the ventilation part 41a directly contacts the member of the device to which the container 41 is attached by the back plate 42 on which the protruding part 42a is formed. Can be prevented.

  For example, when the member on the back side of the apparatus is molded using polyethylene, which is a kind of synthetic resin, it is preferable to attach the air purification attachment 40 to the apparatus so as to arrange the container 41 as described above.

  When the container 41 is disposed, a slight gap may be formed between the upper edge of the back plate 42 and the upper edge of the back surface of the apparatus. Since the chlorine dioxide gas A immediately after being supplied with a high concentration in the air is not brought into contact with the member on the back surface of the apparatus by the protrusion 42a, the above-mentioned effects can be obtained to some extent although not completely.

(Other)
(Fixing method)
The method for attaching the attachment 20 to the main body of the air purification device 30 is not particularly limited. For example, an adhesive member or the like may be provided between the container 21 of the attachment 20 and the main body, and the attachment 20 may be bonded and fixed to the main body. Moreover, it can replace with the said adhesive member and can also employ | adopt the holder formed so that the container 21 could be attached or detached. In this case, supply or replacement of the chlorine dioxide powder M housed in the housing space 21h of the housing body 21 is preferable because it can be made easier than when the housing body 21 is fixed to the main body.

  Further, when an adhesive or the like is provided on the back plate 22a of the container 21 and bonded and fixed to the main body of the air purification device 30, the shape of the bonding surface of the back plate 22a, that is, the main body of the air purification device 30 is fixed. It is preferable that the shape of the surface to be attached is formed so that the container 21 of the main body is the same as the shape of the attachment position.

  That is, if the shape of the attachment position of the main body is flat, the shape of the back surface of the back plate 22a is also formed flat. If the shape of the attachment position of the main body is curved, the curvature is substantially the same as the curvature deformation. The shape of the back surface of the back plate 22a is formed so as to have a radius. Then, since no gap is formed between the back surface of the back plate 22a of the container 21 and the surface at the mounting position of the main body portion of the air purification device 30, the attachment 20 is firmly fixed to the main body portion of the air purification device 30. Can be installed.

(Ventilation part shape)
Furthermore, since the ventilation part 21a of the container 21 should just supply the chlorine dioxide gas A from the storage space 21h outside the container 21, the shape of the ventilation part 21a is not specifically limited.
For example, if the shape of the chlorine dioxide to be stored is powder, a fine through hole may be used as the ventilation portion 21a. If the ventilation part 21a is such a fine through-hole, the chlorine dioxide powder M can be prevented from spilling.
On the other hand, as shown in FIG. 2, if the ventilation portion 21a has a structure having a plurality of through holes of a certain size, the chlorine dioxide powder M is replenished from the ventilation portion 21a to the accommodation space 21h of the accommodation body 21. It becomes possible.

Can be efficiently reacted with moisture in the air.

(Description of air purifier)
Next, an example of the air cleaner of the present embodiment will be described.
In the above example, the case where the air purification attachment 20 is used by being attached to the lower side of the side blowing portion 32a of the air purification device 30 has been described. However, a configuration in which both are integrated may be employed.

  Specifically, as shown in FIG. 1, the air supply device is an air purification device 30, and the air purification attachment 20 is disposed on a side surface of the main body below a side surface blowing portion 32 a provided on a side surface of the main body. And the vent 21a of the container 21 is provided below the side blowing part 32a.

  Then, since the air purification attachment 20 is configured as described above, the chlorine dioxide powder M accommodated in the container 21 reacts with moisture contained in the air to generate chlorine dioxide gas A, and the chlorine dioxide. Gas A is supplied to the outside from the vent 21a.

  Then, the flow direction of the chlorine dioxide gas A supplied from the ventilation part 21a of the container 21 can be made to intersect with the flow direction of the air Ca discharged from the side face blowing part 32a.

  Moreover, since the air purification attachment 20 is integrated with the side surface of the main body, the air purification attachment 20 is not dropped or lost from the main body, which is preferable.

  Furthermore, in addition to the function of purifying the air sucked inside the main body, such an air cleaner can exert the same function as the air purification attachment 20 described above. In other words, the air purifier is provided on the side of the main body with the function of sucking the air into the main body, purifying the sucked air with the air purifying means provided inside, and supplying it to the outside of the main body. Both of the functions of purifying the air with the chlorine dioxide gas A supplied from the ventilation portion 21a of the container 21 of the air purification attachment 20 thus obtained can be provided.

  Then, this air cleaner can first purify the sucked air by the air purifying means provided in the main body. Next, the air discharged to the outside of the main body can be purified by the chlorine dioxide gas A supplied from the vent 21 a of the container 21 of the air purification attachment 20. Further, since the supplied chlorine dioxide gas A can be placed in the flow direction of the discharged air, the chlorine dioxide gas A can be distributed over a wide range. Then, the air which contacted the distributed chlorine dioxide gas A can also be purified. In other words, such an air purifier can purify the air sucked into the main body in two stages, and can also purify the air before sucking with the chlorine dioxide gas A. In other words, such an air cleaner can purify air in three stages.

  Since the air cleaner is configured as described above, the air that the person breathes can be purified by the chlorine dioxide gas A by the three-stage purification means, so that the person is infected with a virus or the like due to the air. Can be effectively prevented.

In addition, although the chlorine dioxide powder M supplied in the container 21 of the air purification attachment 20 with which the air cleaner of this embodiment is equipped may be used with powder, the package MP enclosed in the bag mentioned above. May be supplied into the container 21.
Particularly, in the case of the packaging body MP, the housing body 21 of the air purification attachment 20 includes the fixed portion 22 and the movable portion 23 in order to easily supply the packaging body MP to the housing space 21h in the housing body 21. Is preferable.

  The air purification attachment and the air purifier of the present invention are suitable for tools and devices for purifying air by sterilizing viruses in the air.
