Embodiments for Carrying Out the Invention

[0014] Hereinafter, an embodiment of the deodorizing device according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the deodorizing device seen from the front, FIG. 2 is a perspective view of the deodorizing device seen from the rear, and FIG. 3 is a perspective view of the deodorizing device showing the state where the lid portion is opened. In the following, for convenience of explanation, the description may be based on the directions within the drawings of each figure, but the present invention is not limited by the definition of these directions.

[0015] As shown in FIGS. 1 to 3, the deodorizing device according to the present embodiment includes a housing 1 that can be arranged so as to face the exhaust port of an automobile air conditioner. The housing 1 houses a chlorine dioxide generator 2 and a deodorizing member 3 for the interior of the vehicle. The chlorine dioxide generator 2 used in the present embodiment is mainly for removing the malodor in the exhaust port of the air conditioner, and the deodorizing member 3 is mainly for removing the malodor in the vehicle interior (the space for arranging people and luggage). Hereinafter, these members will be described in detail.

[0016] <1. Housing> As shown in FIGS. 1 to 3, the housing 1 has a main body portion 11 having an opening portion 111 at the upper part, a lid portion 12 that closes the opening portion 111 of the main body portion 11, and a hinge portion 13 that connects the main body portion 11 and the lid portion 12 so as to be foldable.

[0017] FIG. 4 is a perspective view of the main body portion. As shown in FIG. 4, the main body portion 11 has a trapezoidal bottom wall portion 112 and side wall portions 113 to 115 that stand up from the periphery of the bottom wall portion 112, and the upper ends of the side wall portions 113 to 115 form the opening portion 111 of the main body portion 11. The side wall portion has a first wall portion 113 facing the exhaust port of the air conditioner, a second wall portion 114 on the side opposite to the first wall portion 113, and a pair of third wall portions 115 that connect both ends of the first wall portion 113 and the second wall portion 114. The connecting portion between the second wall portion 114 and each third wall portion 115 is curved in an arc shape.

[0018] As shown in FIG. 2, the first wall portion 113 is formed in a flat plate shape, and a mounting portion 116 is provided at the center in the left-right direction thereof. As will be described later, a jig for attaching the housing 1 to the exhaust port louver is attached to this mounting portion 116. Further, at the rear end portion of the upper end of this mounting portion 116, the above-described hinge portion 13 is attached. Furthermore, in the first wall portion 113, a plurality of first vent holes 117 extending in the vertical direction are formed in parallel in portions other than the mounting portion 116. Each first vent hole 117 penetrates the first wall portion 113 and communicates the inside of the housing 1 (the first accommodating portion 101 described later) with the outside. The first wall portion 113 faces the first accommodating portion 101 in which the chlorine dioxide generating agent 2 is accommodated, as will be described later. However, the portion of the first wall portion 113 where the first vent holes 117 are formed faces the portion where the chlorine dioxide generating agent 2 is disposed, as will be described later. Thereby, the generated chlorine dioxide can be efficiently discharged into the air conditioner.

[0019] As shown in FIG. 4, a window portion 118 extending in the vertical direction is formed near the center in the horizontal direction of the second wall portion 114. The window portion 118 penetrates the second wall portion 114 and communicates the inside of the housing 1 (the second accommodating portion 102 described later) with the outside.

[0020] Inside the main body portion 11, a plate-shaped partition portion 119 that connects the opposing third wall portions 115 to each other is provided near the center in the front-rear direction. The partition portion 119 extends upward from the bottom wall portion 112 of the main body portion 11 and extends to a position slightly lower than the upper end of the third wall portion 115. By the partition portion 119, the first accommodating portion 101 is formed at the rear side of the main body portion 11, and the second accommodating portion 102 is formed at the front side of the main body portion 11. The above-described chlorine dioxide generating agent 2 is accommodated in the first accommodating portion 101, and the deodorizing member 3 is accommodated in the second accommodating portion 102.

[0021] As shown in FIG. 3, the lid portion 12 has a plate-shaped lid body 121 that closes the opening 111, and a plate-shaped protrusion 122 formed on the lower surface of the lid body 121. In the lid body 121, a hinge portion 13 is connected to the side along the first wall portion 113. Thereby, the lid portion 12 is configured to pivot about the hinge portion 13 as a pivot center and open and close the opening 111. Further, in the lid body 121, a plurality of second ventilation holes 123 extending in the left-right direction are formed at positions facing the second storage portion 102. The second ventilation holes 123 penetrate the lid body 121 and communicate the second storage portion 102 with the outside.

[0022] The protrusion 122 protrudes downward slightly inside from the outer peripheral edge of the lid body 121. Further, the protrusion 122 is formed along the entire circumference of the outer peripheral edge of the lid body 121, and is configured such that when the lid portion 12 closes the opening 111, the protrusion 122 contacts the inner walls of the side wall portions 113 to 115. Thereby, the lid portion 12 can be held on the main body portion 11. The protrusion 122 has a first portion 1221 that contacts the inner wall surface of the first wall portion 113, and a second portion 1222 that contacts the inner wall surfaces of the second wall portion 114 and the third wall portion 115. The protruding length of the first portion 1221 from the lid body 121 is longer than that of the second portion 1222. The protruding length of the first portion 1221 is preferably, for example, 1.5 times or more the protruding length of the second portion 1222, and more preferably 2 times or more. As shown in FIG. 3, a part of the second portion 1222, for example, the vicinity of the end connected to the first portion 1221, can also have the same protruding length as the first portion 1221.

[0023] <2. Chlorine dioxide generator> The chlorine dioxide generator 2 is not particularly limited as long as it can generate chlorine dioxide. For example, it can be configured as follows. As shown in FIG. 5, the chlorine dioxide generator 2 can be composed of a granular porous carrier carrying a chlorine dioxide raw material and a breathable bag-shaped sheet material 21 that houses the carrier. The sheet material 21 can be formed of, for example, a non-woven fabric. This non-woven fabric can be made difficult to tear, have a predetermined air permeability, and not deteriorate by reacting with chlorine dioxide. As the chlorine dioxide raw material, for example, sodium chlorite can be used, and as the carrier, for example, calcined magnesium silicate can be used. Thereby, sodium chlorite absorbs carbon dioxide gas and water in the air, generating chlorine dioxide gas. As the chlorine dioxide generator, for example, "Chlorocide (registered trademark)" manufactured by Osaka Soda Co., Ltd. can be used.

[0024] The amount of chlorine dioxide generated by this chlorine dioxide generator 2 can be set as follows. For example, the concentration of chlorine dioxide in the airbag after the chlorine dioxide generator 2 is housed in a 5-liter airbag for 1 hour can be about 0.01 to 0.1 ppm. The air permeability of the sheet material 21 and the weight of the carrier can be adjusted so as to achieve such a concentration.

[0025] Also, the generation period of chlorine dioxide from this chlorine dioxide generator 2 can be, for example, 2 to 4 months. This period is longer than the deodorizing effect duration of the drug of the deodorizing member 3 described later (the period until the drug is used up).

[0026] Before use, the chlorine dioxide generator 2 is housed in a gas-impermeable bag (not shown) so that chlorine dioxide does not volatilize. Then, as described later, at the time of use, the bag is opened, the chlorine dioxide generator 2 is taken out, and this is housed in the first housing portion 101. As the gas-impermeable bag, for example, one with aluminum vapor-deposited can be used.

[0027] <3. Deodorizing member> FIG. 6 is a perspective view of the deodorizing member. The deodorizing member 3 includes a transparent container 31 with an open top and a gel-like agent 32 housed in the container 31. A flange 311 is formed at the open top of the container 31. However, as shown in FIG. 6, before use, a gas-impermeable sheet-like lid member 33 is removably attached to the flange 311 of the container 31. The container 31 is generally formed in a rectangular parallelepiped shape, but is shaped to follow the inner wall surface of the second storage portion 102.

[0028] The agent 32 contains deodorizing components such as hydrazide compounds, amine compounds, polyphenols, betaine compounds, amino acid-based compounds, and metal ions, and is configured to decompose the malodorous components of the air in contact with the agent 32 (for example, the acetic acid odor component contained in body odor). Further, the agent 32 is colored so that the remaining amount of the agent 32 can be visually recognized from the outside of the container 31. The duration of the deodorizing effect by the agent, that is, the period from the start of use until the agent is used up (the period until the visually recognized remaining amount becomes 0) can be, for example, 1 to 3 months. Also, the agent is formed in a gel state, thereby suppressing spillage from the container 31.

[0029] As described above, before use, the upper opening of the container 31 is closed with the gas-impermeable lid member 33. However, as will be described later, during use, the lid member 33 is removed, and the container 31 is housed in the second storage portion 102 with the agent 32 exposed from the opening.

[0030] <4. Method of Using the Deodorizing Device> Next, a method of using the deodorizing device configured as described above will be explained. First, open the gas-impermeable bag containing the chlorine dioxide generator 2 and take out the chlorine dioxide generator 2. Then, as shown in FIG. 7, remove the lid portion 12 of the housing 1 and accommodate the chlorine dioxide generator 2 in the first accommodating portion 101. Next, remove the lid member 33 of the deodorizing member 3 and accommodate the container 31 in the second accommodating portion 102 with the chemical agent 32 exposed from the upper opening. As shown in FIG. 1, when the deodorizing member 3 is accommodated in the second accommodating portion 102, the deodorizing member 3 is visible from the outside through the window portion 118. That is, since the container 31 of the deodorizing member 3 is transparent, the remaining amount of the chemical agent 32 can be visually recognized through the window portion 118. Subsequently, close the opening 111 of the main body portion 11 with the lid portion 12 and attach the jig 7 to the attachment portion 116. Then, as shown in FIG. 8, attach the jig 7 to the louver 81 of the exhaust port 8 of the air conditioner. Thus, the preparation for using the deodorizing device is completed.

[0031] The deodorizing device operates as follows. As shown in FIG. 8, chlorine dioxide volatilizes from the chlorine dioxide generator 2 accommodated in the first accommodating portion 101. This chlorine dioxide volatilizes into the exhaust port 8 through the first vent hole 117 when the air conditioner is off, and decomposes the malodorous components (for example, geosmin that generates a moldy odor) in the exhaust port 8. Thereby, the malodor discharged from the exhaust port 8 when the air conditioner is turned on is removed.

[0032] Regarding the malodor in the vehicle interior, the air that has entered the housing 1 from the second vent hole 123 can be removed by coming into contact with the chemical agent 32. That is, the malodorous components (for example, the acetic acid odor component contained in body odor) contained in the air that has entered the housing 1 are decomposed by the chemical agent 32. Then, the air in which the malodorous components have been decomposed is discharged from the second vent hole 123 into the vehicle interior. In this way, the air circulating in the vehicle interior enters the housing 1 from the second vent hole 123, comes into contact with the chemical agent 32, and is then discharged from the second vent hole 123, and this is repeated, thereby removing the malodor of the air in the vehicle interior.

[0033] As described above, the deodorizing device of the present embodiment can remove the malodor from the exhaust port 8 of the air conditioner and the malodor in the vehicle interior.

[0034] <5. Features> According to the deodorizing device configured as described above, the following effects can be obtained.

[0035] (1) Since the generation of chlorine dioxide from the chlorine dioxide generator 2 cannot be visually recognized, it is difficult to know when the effect of chlorine dioxide is lost. Therefore, in the present embodiment, in addition to the chlorine dioxide generator, a chemical agent 32 containing a deodorizing component is provided, and the remaining amount of the chemical agent 32 can be visually recognized through the window portion 118. Therefore, in the present embodiment, regardless of the available period of chlorine dioxide, the remaining amount of the chemical agent 32 is used as a guide for the replacement time of the deodorizing device. Further, in the present embodiment, since the effective generation period of chlorine dioxide is made longer than the time when the chemical agent 32 is used up, the generation of chlorine dioxide does not end before the remaining amount of the chemical agent 32 becomes zero. Therefore, while the chemical agent 32 remains, the generation of chlorine dioxide can be guaranteed.

[0036] (2) Since the partition portion 119 that partitions the first accommodation portion 101 and the second accommodation portion 102 is provided in the main body portion 11 of the housing 1, the chlorine dioxide generator 2 and the deodorizing member 3 can be easily accommodated in the housing 1. Further, since the size of the second accommodation portion 102 is formed such that the side surface of the deodorizing member 3 contacts the inner wall surface of the second accommodation portion 102, it is possible to prevent the deodorizing member 3 from moving within the housing 1.

[0037] As shown in FIG. 9, even when the air discharged from the exhaust port 8 enters from the first ventilation port 117 when the air conditioner is on, the partition portion 119 suppresses the air from entering the second accommodation portion 102. Therefore, it is possible to suppress the use of the chemical agent by the air from the exhaust port 8.

[0038] (3) As shown in FIG. 8, since the second vent 123 is formed above the second accommodating portion 102 in the lid portion 12 of the housing 1, the air flowing in from the second vent 123 can easily come into contact with the chemical agent 32. On the other hand, since no vent is formed above the first accommodating portion 101, chlorine dioxide generated from the chlorine dioxide generating agent 2 in the second accommodating portion 102 is less likely to be discharged into the vehicle interior. As a result, chlorine dioxide can be efficiently discharged from the first vent 117 to the discharge port 6.

[0039] (4) A protrusion 122 extending over the entire circumference is provided on the lower surface of the lid body 121 of the lid portion 12. When the lid portion 12 is closed, the lid portion 12 can be held on the main body portion 11 by the protrusion 122 contacting the inner wall surface of the main body portion 11 of the housing 1. Further, since the protruding length of the first portion 1221 disposed on the hinge portion 13 side in the protrusion 122 is formed longer than that of the second portion 1222, when the lid portion 12 is closed, the chlorine dioxide generating agent 2 accommodated in the first accommodating portion 101 can be pushed downward. That is, as shown in FIG. 10, after the first portion 1221 pushes the chlorine dioxide generating agent 2 downward while rotating around the hinge portion 13, since the first portion 1221 contacts the inner wall surface of the main body portion 11, it is possible to suppress the sheet material 21 of the chlorine dioxide generating agent 2 from being sandwiched between the first portion 1221 and the inner wall surface of the main body portion 11. As a result, it is possible to suppress the sheet material 21 from being torn.

[0040] Further, the hinge portion 13 is connected to be separated from the first wall portion 113 via the attachment portion 116. Therefore, for example, compared to providing the hinge portion 13 on the front end side of the attachment portion 116 or on the first wall portion 113, the distance from the rotation center of the lid portion 12 to the first portion 1221 becomes longer, and the movable range of the first portion 1221 becomes larger. As a result, the chlorine dioxide generating agent 2 can be easily pushed by the first portion 1221.

[0041] (5) The effect of the chlorine dioxide generator 2 of the deodorizing device according to this embodiment was verified as follows. First, an air conditioner pipe was prepared, and the deodorizing device was placed at one end of the pipe. Then, 23 hours later (the average parking time of one day), when the concentration of chlorine dioxide at the other end of the pipe was measured, it was 0.01 ppm or more. Since the inventor had confirmed the deodorizing effect on geosmin when the concentration of chlorine dioxide was 0.01 ppm or more, it was found that by using the deodorizing device of this embodiment, it is possible to deodorize the bad odor caused by geosmin throughout the entire pipe.

[0042] Note that at the above concentration, the acetic acid odor mainly generated from body odor, which is the cause of the bad odor in the vehicle, cannot be sufficiently removed only by the chlorine dioxide generator 2. Therefore, in addition to the chlorine dioxide generator 2, by providing a chemical agent 32 for removing the bad odor in the vehicle, it is possible to remove both the bad odor in the air conditioner pipe and the bad odor in the vehicle.

[0043] <6. Modification Example> As described above, an embodiment of the present invention has been described. However, the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit thereof. The following modification examples can be combined as appropriate. Also, the following modification examples can be combined with the above-described embodiment as appropriate.

[0044] (1) In the above embodiment, as the chemical agent 32 of the deodorizing member 3, a deodorizing component that decomposes acetic acid odor is contained, but it is not limited thereto. As long as the chemical agent contains a deodorizing component that can remove the bad odor in the vehicle that cannot be removed or is difficult to remove by chlorine dioxide, it is sufficient. In addition to this, it can also contain a fragrance having a fragrant component. Also, although the chemical agent is colored so as to be easily visible, it does not necessarily have to be colored as long as the remaining amount can be visually recognized from the outside through the window portion 118. In the above embodiment, as the deodorizing member 3, a container 31 containing the chemical agent 32 is housed in the second housing portion 102, but the form of the deodorizing member 3 is not particularly limited as long as it can remove the bad odor in the vehicle.

[0045] (2) The partition 119 is not necessarily required. It is sufficient if the first accommodation part 101 and the second accommodation part 102 capable of accommodating the chlorine dioxide generating agent 2 and the deodorizing member 3 are provided in the housing 1.

[0046] (3) The shape of the housing 1 is not particularly limited either. It is sufficient if the first accommodation part 101, the second accommodation part 102, at least one ventilation opening, and the window part 118 are provided. Therefore, it is not limited to configuring the housing 1 with the main body part 11 and the lid part 12 as in the above embodiment, as long as the chlorine dioxide generating agent 2 and the deodorizing member 3 can be accommodated. Also, the positions and shapes of the first ventilation opening 117 and the second ventilation opening 123 are not particularly limited. Further, the position and shape of the window part 118 are not particularly limited, as long as it is configured to be able to visually recognize the remaining amount of the chemical agent 32 of the deodorizing member 3. Regarding the ventilation opening, in the above embodiment, it is formed separately into the first ventilation opening 117 and the second ventilation opening 123, but it does not have to be limited to this. For example, only one ventilation opening may be provided such that both the first accommodation part 101 and the second accommodation part 102 communicate with the outside. That is, at least one ventilation opening that communicates the inside and the outside of the housing 1 is provided, and at least a part of the generated chlorine dioxide flows toward the exhaust port 8 side, and the air from the outside is configured to contact the chemical agent. Also, in addition to the ventilation openings 117 and 123 in the above embodiment, one or more additional ventilation openings can also be provided.

[0047] (4) In the above embodiment, the form of the attachment part 116 to the housing 1 is not particularly limited, as long as the first ventilation opening 117 of the housing 1 can be opposed to the exhaust port of the air conditioner. Therefore, the housing 1 may not be attached to the louver of the exhaust port, but may be a part around the exhaust port. Also, the attachment part 116 may not be provided on the housing 1, and the housing 1 may be opposed to the exhaust port via other members.

[0048] (5) In the above-described embodiment, the generation period of chlorine dioxide in the chlorine dioxide generator 2 is set to be longer than the time until the agent 32 is used up, but it is not limited thereto. That is, the generation period of chlorine dioxide and the time until the agent 32 is used up may be substantially the same, or the generation period of chlorine dioxide may be shorter than the time until the agent 32 is used up. However, when the generation period of chlorine dioxide is shorter than the time until the agent 32 is used up, it is preferable that the difference between the two is not significantly large. For example, the difference between the two is preferably within 3 months, more preferably within 2 months, and particularly preferably within 1 month.
