Best Mode for Carrying Out the Invention

[0010] 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 as seen from the front, FIG. 2 is a perspective view of the deodorizing device as seen from the rear, and FIG. 3 is a perspective view of the deodorizing device showing the state where the lid portion is open. In the following, for convenience of explanation, the description may be made based on the directions within the drawings of each figure, but the present invention is not limited by the definition of these directions.

[0011] As shown in FIGS. 1 to 3, the deodorizing device according to the present embodiment includes a housing 1 that can be arranged to face the exhaust port of an automobile air conditioner. A chlorine dioxide generating agent 2 is accommodated in the housing 1. The chlorine dioxide generating agent 2 used in the present embodiment is mainly for removing the malodor in the exhaust port of the air conditioner. Hereinafter, these members will be described in detail.

[0012] <1. Housing> As shown in FIGS. 1 to 3, the housing 1 has a main body portion 11 having an opening 111 at the upper part, a lid portion 12 that closes the opening 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. The main body portion 11 has a rectangular bottom wall portion 112 and side wall portions 113 to 115 that stand up from the periphery of the bottom wall portion 112. The upper ends of the side wall portions form the opening 111 of the main body portion 11. The side wall portions include a first wall portion 113 that faces 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. A storage space for storing the chlorine dioxide generating agent 2 is formed by the bottom wall portion 112 and the side wall portions 113 to 115.

[0013] 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, the hinge portion 13 described above is attached to the rear end portion of the upper end of this mounting portion 116. In the first wall portion 113, a plurality of ventilation holes 117 extending in the vertical direction are formed in parallel in portions other than the mounting portion 116. Each first ventilation hole 117 penetrates the first wall portion 113 and communicates the accommodation space of the housing 1 with the outside. The first wall portion 113 faces the first accommodation 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 ventilation 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.

[0014] 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, the 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 and open and close the opening 111.

[0015] The protruding portion 122 protrudes downward slightly inside from the outer peripheral edge of the lid body 121. Also, the protruding portion 122 is formed along the entire circumference of the outer peripheral edge of the lid body 121, and when the lid portion 12 closes the opening portion 111, the protruding portion 122 is configured to contact the inner walls of the side wall portions 113 to 115. Thereby, the lid portion 12 can be held by the main body portion 11. The protruding portion 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 downward is longer than that of the second portion 1222. The protruding length 1221 of the first portion is preferably, for example, 1.5 times or more, and more preferably 2 times or more the protruding length of the second portion 1222. 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.

[0016] <2. Chlorine Dioxide Generator> The chlorine dioxide generator 2 is not particularly limited as long as it can generate chlorine dioxide, and can be configured, for example, as follows. As shown in FIG. 4, the chlorine dioxide generator 2 can be composed of a granular porous carrier on which a chlorine dioxide raw material is supported 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.

[0017] 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 accommodating the chlorine dioxide generator 2 in a 5-liter airbag for 1 hour can be set to 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 obtain such a concentration.

[0018] In addition, the generation period of chlorine dioxide from this chlorine dioxide generator 2 can be, for example, 2 to 4 months.

[0019] Before use, the chlorine dioxide generator 2 is accommodated in a gas-impermeable bag (not shown) so that chlorine dioxide does not volatilize. Then, as will be described later, at the time of use, the bag is opened, the chlorine dioxide generator 2 is taken out, and this is accommodated in the accommodation space. As the gas-impermeable bag, for example, a bag vapor-deposited with aluminum can be used.

[0020] <3. Method of using the deodorizing device> Next, the method of using the deodorizing device configured as described above will be described. 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. 5, remove the lid portion 12 of the housing 1 and accommodate the chlorine dioxide generator 2 in the accommodation space. Next, 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. 6, attach the jig 7 to the louver 81 of the exhaust port 8 of the air conditioner. In this way, the preparation for using the deodorizing device is completed.

[0021] The deodorizing device operates as follows. First, chlorine dioxide volatilizes from the chlorine dioxide generator 2 accommodated in the accommodation space. This chlorine dioxide volatilizes into the exhaust port 8 through the ventilation port 117 when the air conditioner is off, and decomposes the malodorous components (for example, geosmin that generates a moldy smell) in the exhaust port 8. Thereby, the malodor discharged from the exhaust port 8 when the air conditioner is turned on is removed.

[0022] <4. Features> According to the deodorizing device configured as described above, the following effects can be obtained.

[0023] (1) In the chlorine dioxide generating agent 2 according to the present embodiment, sodium chlorite absorbs carbon dioxide gas and water in the air, generating chlorine dioxide gas. Therefore, a device such as an ultraviolet irradiation lamp for vaporizing chlorine dioxide as in the conventional example is not required, and the deodorizing device can be downsized.

[0024] (2) 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 protrusion 122 contacts the inner wall surface of the main body portion 11 of the housing 1, so that the lid portion 12 can be held by the main body portion 11. 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. 7, after the first portion 1221 pushes the chlorine dioxide generating agent 2 downward while rotating around the hinge portion 13, the first portion 1221 contacts the inner wall surface of the main body portion 11. Therefore, 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.

[0025] 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 with 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 turning center of the lid portion 12 to the first portion 1221 becomes longer, and the movable range of the first portion 1221 becomes larger. Thereby, it is possible to make it easier to push the chlorine dioxide generating agent 2 by the first portion 1221.

[0026] (3) 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, after 23 hours (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 was possible to deodorize the bad odor caused by geosmin throughout the entire pipe.

[0027] From the above, the chlorine dioxide generator 2 can remove the bad odor of the air conditioner pipe.

[0028] <5. Modification Example> As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit thereof. The following modification examples can be combined as appropriate. Also, each of the following modification examples can be combined with the above-described embodiment as appropriate.

[0029] (1) The shape of the housing 1 is not particularly limited as long as there is a housing space for accommodating the chlorine dioxide generator and a ventilation port 117. Therefore, it is not limited to configuring the housing 1 with the main body 11 and the lid 12 as in the above embodiment, as long as the chlorine dioxide generator 2 can be accommodated. Also, the position and shape of the ventilation port 117 are not particularly limited, as long as the chlorine dioxide generated from the chlorine dioxide generator can flow through the ventilation port 117 to the exhaust port 8.

[0030] (2) In the above embodiment, the protrusion 122 of the lid 12 is provided over the entire outer peripheral edge of the lid body 121. However, as long as the lid 12 can hold the state of closing the opening 111, a part of the outer peripheral edge may be sufficient. Also, the protruding length may be the same over the entire protrusion 122. Further, the lid 12 may hold the state of closing the opening 111 by a configuration other than the protrusion 122.

[0031] (3) In the above embodiment, the form of the attachment portion 116 on the housing 1 is not particularly limited, as long as the 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 81 of the exhaust port 8, but may be attached to a portion around the exhaust port 8. Further, the attachment portion 116 may not be provided on the housing 1, and the housing 1 may be opposed to the exhaust port 8 via another member.
