  In the adsorbent circulation type deodorizing apparatus disclosed in Patent Document 1, the odorous gas flows through the deodorizing apparatus at a flow rate that soars the granular activated carbon, so the contact time of the odorous gas with the activated carbon is extremely short, The odor contained in the odorous gas cannot be sufficiently adsorbed by the activated carbon, and it is difficult to remove all of the odor from the odorous gas. Further, this adsorbent circulation type deodorizing device does not allow the odorous gas to flow uniformly in the container, so that it is difficult to uniformly flow the odorous gas throughout the support member on which the activated carbon is placed. The activated carbon cannot be uniformly contacted with odorous gas, and all of the activated carbon cannot be used for odor adsorption.

  In the honeycomb deodorizing material disclosed in Patent Document 2, a plurality of cylindrical portions having a honeycomb-shaped air flow path extending in one direction through which air can flow are formed, and air flows through the air flow path. The odor contained in the air is removed, but since the air flow paths extend in one direction in parallel with each other, the air cannot flow from one air flow path to the other air flow path. Pass through these air flow paths quickly, and it is not possible to lengthen the air flow time in the air flow paths. Therefore, when the contact time of air to the honeycomb deodorizing substrate cannot be increased, it is difficult to efficiently use the deodorizing function of the honeycomb deodorizing substrate, and the odor contained in the air cannot be reliably removed There is.

  The objective of this invention is providing the deodorizing apparatus which can remove the odor contained in air reliably.

  The premise of this invention for solving the said subject is the deodorizing apparatus which removes the odor contained in air.

Is made of activated carbon that adsorbs odors and is shaped into a rectangular column that is long in the vertical direction, and has an upper end surface, a lower end surface, and first to fourth side surfaces, and straight in the vertical direction in which air can flow. comprising a plurality of tubular portions of the cross-sectional honeycomb shape adjacent the longitudinal direction and the lateral direction to have a first air flow path of a predetermined length extending the air inlet of the first air passage is opened to the upper end surface And an air outlet opening to an end face, a first air flow path to remove the odor contained in the air flowing through it flows from the air inlet, on their cylindrical portion of the deodorizing cartridge, first side surface of the cartridge A plurality of second pipes of a predetermined length that allow the air to flow through the pipe portion extending in the front-rear direction while being spaced apart in parallel in the vertical direction and the horizontal direction . 2 air flow paths are formed, and the first air flow path is such that a part of the air outlet opening at the lower end surface of the cartridge is closed and the total number of air outlets is smaller than the total number of air inlets. The amount of air that can flow out from the air inlet is less than the amount of air that can flow in from the air inlet, the number of the second air flow paths is smaller than the number of the first air flow paths, and the opening area thereof is the first air. Smaller than the opening area of the flow path, open on the first side of the cartridge The open end and the open end that opens to the third side surface are closed and extend into the cartridge. In the deodorizing cartridge, a melted synthetic resin is applied to a part of the lower end surface, and the lower end surface is formed by the cured synthetic resin. The air outlet of a part of the first air flow path is closed by coating, or an adhesive tape is applied to a part of the lower end surface, and the lower end surface is covered with the adhesive tape to cover the first air flow After the air outlet of a part of the passage is blocked and the second air flow path is perforated, the synthetic resin melted is applied to the first and third side surfaces, and the first and third side surfaces are covered with the cured synthetic resin. Thus, the open ends of the second air flow path are closed, or the first and third side surfaces are covered with the adhesive tape and the first and third side surfaces are covered with the adhesive tape. Those open ends of the road are blocked In the deodorizing cartridge, the first air flow path and the second air flow path are connected to each other , adjacent first air flow paths are connected via the second air flow path, and flowed in from the air inlet. While the air flows through the first air flow path, the air flows from the first air flow path into the second air flow path and flows through the second air flow path, and the other first air flow from the second air flow path. That is, the air flows again into the air flow channel and flows out from the air outlet while flowing through the other first air flow channel .

As an example of the present invention, the total number of air outlets of the first air flow path opening in the lower end surface is in a range of 1/2 to 1/5 of the total number of air inlets of the first air flow path opening in the upper end surface. It is in .

As an example of the present invention, the cylindrical portions of the deodorizing cartridge are formed by perforating the cylindrical portion from the second side surface to the fourth side surface of the cartridge, and are laterally separated in parallel in the vertical direction and the front-rear direction. A plurality of third air passages having a predetermined length that extend in a straight line and through which air can flow are formed, and the number of third air passages is smaller than the number of first air passages, The opening area is smaller than the opening area of the first air flow path, the opening end that opens to the second side surface of the cartridge and the opening end that opens to the fourth side surface are closed and extend inside the cartridge. After the third air channel is perforated, the melted synthetic resin is applied to the second and fourth side surfaces, and the open ends are closed by covering the second and fourth side surfaces with the cured synthetic resin, or , Glued to second and fourth sides By covering the second and fourth side surfaces with the adhesive tape and covering the second and fourth side surfaces, the open ends are closed, and the deodorizing cartridge is connected to the first air flow path and the third air flow path in the interior thereof. Adjacent first air flow paths are connected to each other via a third air flow path, and the air flowing in from the air inflow port flows through the first air flow path, and the second air flow from the first air flow path. And the second air flow path and the third air flow path through the second air flow path and the third air flow path, and the other first air flow path from the second and third air flow paths to the other first air flow path. It flows out from the air outlet while flowing through one air flow path .

  As another example of the present invention, a slit that opens in the direction around the storage case is formed on the peripheral wall extending above the deodorizing cartridge and extending to the upper end of the storage case, and the fragrance sheet that diffuses a predetermined fragrance is formed from the slit to the case. It is inserted in the inside of the removably.

  As another example of the present invention, the deodorizing device includes a pedestal connected to the lower end of the storage case, and a battery that supplies electricity to the blower fan is detachably stored in the pedestal.

  As another example of the present invention, the deodorizing apparatus includes a pedestal connected to the lower end of the storage case, and a flexible solar panel that supplies electricity to the blower fan is installed on the outer peripheral surface of the pedestal.

  As another example of the present invention, the deodorizing device is provided with a rotation speed variable circuit that varies the rotation speed of the blower fan.

As another example of the present invention, the rotational speed of the blower fan is in the range of 60 to 480 r / min, and the flow velocity of the air flowing through the air flow path of the cylindrical portion of the deodorizing cartridge is 0.01 to 0.1 m ³ / sec. It is in the range.

  As another example of the present invention, the vertical dimension of the first air flow path of the deodorizing cartridge is in the range of 3 to 30 cm.

As another example of the present invention, the area of the end faces of the deodorizing cartridge located on the air inlet side of the first air passage is in the range of 9～400Cm ^2, the air flow outlet side of the first air channel area under end face of the deodorizing cartridge located in the range of 9~400cm ^2.

As another example of the present invention, the number of first air flow paths in the cylindrical portion per 1 cm ^{2 of} the deodorizing cartridge is in the range of 30-50 .

  According to the deodorizing apparatus of the present invention, the air taken into the case from the through hole by the blower fan passes through the air flow paths extending in the vertical direction from the lower end to the upper end of the deodorizing cartridge, and thus is included in the air. Odor is surely removed at the cylinder portion (activated carbon) of the deodorizing cartridge, and clean air can be made, and clean air can be sent to the outside from the top opening of the case. Since the deodorizing cartridge is located directly above the blower fan, the deodorizing device can uniformly flow the air taken into the inside of the case through the through hole to all the air flow paths of the deodorizing cartridge. The function can be utilized to the maximum and the deodorization efficiency in the apparatus can be improved. In the deodorizing device, a plurality of second air passages having a predetermined length extending in a first intersecting direction in which air can flow through the first air passages are formed in those tubular portions of the deodorizing cartridge. Since the first air flow path and the second air flow path are connected to each other, air flowing in from the air inlet of the first air flow path passes through the second air flow path as well as the first air flow path. And flows into the other first air flow path from the second air flow path, and further flows through the second air flow path and flows into the other first air flow path. In the deodorization device, air flows through the first air flow path and the second air flow path of the deodorization cartridge, and the air becomes vortex or turbulent at the intersection of the first air flow path and the second air flow path. Therefore, the air resistance increases and the flow rate of the air flowing through the air flow path decreases, so that the air flow time in the air flow path can be made sufficiently long and the cylinder (active carbon) can be The contact time of air can be made sufficiently long, and the odor contained in the air can be reliably removed.

  When the number of second air flow paths is larger than the number of first air flow paths and the opening area of the second air flow paths is larger than the opening area of the first air flow paths, the deodorizing device has one second air flow path. There are cases where a large number of adjacent first air flow paths are connected by an air flow path, and a large number of fine air flow paths cannot be stretched around the deodorizing cartridge, but the number of second air flow paths is the number of the first air flow paths. Since the opening area of the second air flow path is smaller than the number of flow paths and the opening area of the first air flow path, a number of adjacent first air flow paths are connected by the second air flow path. In addition, a large number of fine air flow paths can be stretched around the deodorizing cartridge.

In the deodorizing device, the opening end of the second air flow path formed in the cylinder portion of the deodorizing cartridge is closed, and the second air flow path extends into the deodorizing cartridge. The air flowing in from the air does not flow out from the open end (air outlet) of the second air flow path to the outside of the cartridge while flowing through the first and second air flow paths. The air can be passed from the air inlet to the air outlet. Since the deodorization apparatus flows out the air outlet of the first air flow path after the air flows through the first air flow path and the second air flow path of the deodorization cartridge, the air flow in the air flow path While being able to lengthen time, the contact time of the air with respect to a cylinder part (activated carbon) can be lengthened, and the odor contained in air can be removed reliably.

  A plurality of third air passages having a predetermined length extending in a third direction through which air can flow crossing the first and second air passages are formed in the cylindrical portions of the deodorizing cartridge. The deodorizing device in which the 1 air flow path and the third air flow path are connected, and the air flowing in from the air inflow port flows through the first air flow path, the second air flow path, and the third air flow path. The air flowing in from the air inlet of the first air channel flows not only through the first air channel and the second air channel but also through the third air channel, and from the third air channel to the other The air flows into the first air flow path and the second air flow path, further flows through the third air flow path, and flows into the other first air flow path and the second air flow path. In the deodorizing device, air flows through the first to third air flow paths of the deodorizing cartridge, and air becomes vortex or turbulent at the intersection of the first to third air flow paths, and the air resistance increases accordingly. Since the flow rate of the air flowing through the air flow path is reduced, the air flow time in the air flow path can be made sufficiently long, and the contact time of the air with respect to the cylindrical portion (activated carbon) is made sufficiently long. The odor contained in the air can be removed reliably.

  In the deodorizing device, when the number of the third air flow paths is larger than the number of the first air flow paths and the opening area of the third air flow path is larger than the opening area of the first air flow path, There are cases where a large number of adjacent first air flow paths are connected by an air flow path, and a large number of fine air flow paths cannot be stretched around the deodorizing cartridge, but the number of third air flow paths is the first air flow. Since the opening area of the third air flow path is smaller than the number of the flow paths and the opening area of the first air flow path, a number of adjacent first air flow paths are connected by the second air flow path. In addition, a large number of fine air flow paths can be stretched around the deodorizing cartridge.

In the deodorizing device, since the open end of the third air flow path formed in the cylinder portion of the deodorizing cartridge is closed and the third air flow path extends into the deodorizing cartridge, the air inlet of the first air flow path The air flowing in from the first air flow does not flow out from the open end (air outlet) of the third air flow path to the outside of the cartridge while flowing through the first to third air flow paths. The air can be passed from the air inlet to the air outlet. Since the deodorizing device flows out from the air outlet of the first air flow channel after the air flows through the first to third air flow channels of the deodorizing cartridge, the air flow time in the air flow channel is lengthened. In addition, it is possible to lengthen the contact time of the air with respect to the cylindrical portion (activated carbon), and it is possible to reliably remove the odor contained in the air.

In the deodorizing device, the air outlets of some of the first air passages of the first air passages of the deodorizing cartridge are closed, and the total number of air outlets is smaller than the total number of air inlets. The amount of air flowing out from the outlet becomes smaller than the amount of air flowing in from the air inlet, and the flow speed of air flowing through each air flow path is reduced accordingly, and the air flow time in each air flow path The contact time of the air with respect to the cylinder part (activated carbon) can be lengthened, and the odor contained in the air can be reliably removed.

  A slit that opens in the direction around the storage case is formed on the peripheral wall that extends above the deodorizing cartridge and extends to the upper end of the storage case, and a fragrance sheet that dissipates a predetermined fragrance is removably inserted into the case from the slit. In the deodorizing device, since the fragrance is given to the air cleaned by the deodorizing cartridge by the fragrance sheet, the scented air can be sent to the outside from the top opening of the case while removing the odor contained in the air. it can. The deodorizing device can be used for aroma therapy because the purified air is sent as aroma.

  A deodorizing device that includes a pedestal connected to the lower end of the storage case and in which a battery that supplies electricity to the blower fan is detachably stored in the pedestal is driven from the through hole by driving the blower fan using the battery. The air taken inside can be passed through those air flow paths of the deodorizing cartridge, and the odor contained in the air can be surely removed in the cylinder part (activated carbon) of the deodorizing cartridge to create clean air. Clean air can be sent to the outside from the top opening of the case.

  A deodorizing device that includes a pedestal connected to the lower end of the storage case and has a flexible solar panel installed on the outer peripheral surface of the pedestal for supplying electricity to the blower fan, drives the blower fan using the flexible solar panel, Air taken inside the case from the through hole can be passed through these air flow paths of the deodorizing cartridge, and the odor contained in the air is surely removed in the cylinder part (activated carbon) of the deodorizing cartridge, so that clean air And clean air can be sent to the outside from the top opening of the case. Since the deodorization device drives the blower fan using the power generation function of the solar panel, it can be made into an energy-saving type deodorization device that uses only light energy, which can save energy and puts a burden on the environment. There is nothing.

  The deodorizing apparatus in which the rotation speed variable circuit for changing the rotation speed of the blower fan is installed is caused to flow through these air flow paths of the deodorization cartridge by changing the rotation speed of the blower fan using the rotation speed variable circuit. The flow rate of air can be changed, and the flow rate of air can be set to a flow rate that maximizes the deodorizing function of the deodorizing cartridge. Since the deodorizing device can make full use of the deodorizing function of the deodorizing cartridge, the odor contained in the air is surely removed in the cylinder part (activated carbon) of the deodorizing cartridge, so that clean air can be made and Air can be sent to the outside from the top opening of the case.

The deodorizing device in which the rotational speed of the blower fan is in the range of 60 to 480 r / min and the flow rate of the air flowing through the air flow path of the cylindrical member of the deodorizing cartridge is in the range of 0.01 to 0.1 m ³ / sec By slowly rotating the fan and setting the air flow rate within the above range, the contact time of the air with the cylinder part (activated carbon) of the deodorizing cartridge can be extended, so that the odor contained in the air is removed from the cylinder part of the deodorizing cartridge. Can be adsorbed sufficiently, and the odor contained in the air can be surely removed.

  In the deodorizing apparatus in which the vertical dimension of the first air flow path of the cylinder portion of the deodorizing cartridge is in the range of 3 to 30 cm, the length of the first air flow path is set in the above range so that each air flow The air flow time in the road can be made sufficiently long, and the contact time of the air with respect to the tube portion (activated carbon) can be made sufficiently long, so that the odor contained in the air can be reliably removed. Since the deodorizing device can reliably remove odors contained in the air at the cylinder portion of the deodorizing cartridge, it can produce clean air and can send clean air to the outside from the top opening of the case. .

The area of one end surface of the deodorizing cartridge located on the air inlet side of the first air passage is in the range of 9~400cm ^2, the area of the other end surface of the deodorizing cartridge located on the air flow outlet side of the first air channel In the deodorizing apparatus having a range of 9 to 400 cm ^2, the area of one end surface and the other end surface of the deodorizing cartridge is in the above range, so that a predetermined amount of air is passed through each air flow path to the cylinder (activated carbon). The odor contained in the air can be surely removed. Since the deodorizing device can reliably remove odors contained in the air at the cylinder portion of the deodorizing cartridge, it can produce clean air and can send clean air to the outside from the top opening of the case. .

Since the number of the 1st air flow paths per 1 cm < ² > of a deodorizing cartridge is in the said range, the deodorizing apparatus in which the number of the 1st air flow paths of the cylinder part per 1 cm < ² > of a deodorizing cartridge is in the said range, A predetermined amount of air can be caused to flow through each air flow path and be brought into contact with the cylindrical portion (activated carbon), so that odor contained in the air can be reliably removed. Since the deodorizing apparatus can reliably remove odors contained in the air in the cylindrical material assembly, it can make clean air and can send clean air to the outside from the top opening of the case.

The cylindrical portions 37 of the cartridge 14A are made of activated carbon having a high odor adsorbing function (including a function of adsorbing radioactive substances such as iodine and cesium).

  The cylindrical portions 37 are adjacent in the front-rear direction and the lateral direction, and extend in the vertical direction in parallel with each other. The cylindrical portion 37 has a first air flow path 38 having a predetermined length through which air can flow. In addition to the first air flow path 38, a plurality of second air flow paths 39 having a predetermined length through which air can flow are formed in the cylindrical portions 37. As shown in FIGS. 4 and 5, the first air flow path 38 has a honeycomb shape having a regular hexagonal cross section, and extends in the vertical direction in parallel with each other. The first air flow path 38 has an air inlet 40 that opens at one end (the upper end surface 31 of the cartridge 14A) and an air outlet 41 that opens at the other end (the lower end surface 32 of the cartridge 14A). It penetrates between the upper and lower end surfaces 31 and 32 of 14A.

  On the lower end surface 32 of the deodorizing cartridge 14 </ b> A, as shown in FIG. 5, the air outlets 41 of all the first air passages 38 are not opened, and some of the air in the first air passages 38 is opened. The air outlet 41 of the flow path 38 is closed (the frame-shaped portion of the lower end face 32 in FIG. 5), and the air outlet 41 of some of the air flow paths 38 is opened (the center of the lower end face 32 in FIG. 5). Square part). Therefore, the total number of air outlets 41 is smaller than the total number of air inlets 40. The total number of air outlets 41 is adjusted to a range of ½ to 1/5 of the total number of air inlets 40. The total number of the air outlets 41 and the total number of the air inlets 40 may be the same without closing the air outlets 41 of some of the first air paths 38. .

  The second air flow path 39 is spaced in parallel in the vertical direction and the horizontal direction, and extends in the front-rear direction (first crossing direction) intersecting the first air flow path 38. The second air channel 39 has a circular cross-sectional shape. The second air flow path 39 has an open end (air outlet) that opens to the first side surface 33 of the cartridge 14A closed, and an open end (air outlet) that opens to the third side surface 35 of the cartridge 14A closes. Yes. The second air flow path 39 is closed at the open ends of the first and third side surfaces 33 and 35 of the cartridge 14A, does not penetrate the first side surface 33 and the third side surface 35, and It extends only inside.

  The first air flow path 38 and the second air flow path 39 intersect with each other inside the cartridge 14A so that they are substantially orthogonal to each other. The first air flow path 38 and the second air flow path 39 are the center line L2 of the first air flow path 38 and the center of the second air flow path 39 inside the cartridge 14A, as shown by a one-dot chain line in FIG. The line L3 intersects at the center of the air flow paths 38 and 39.

  The number of the second air passages 39 is smaller than the number of the first air passages 38, and the opening area thereof is smaller than the opening area of the first air passages 38. When the number of the second air flow paths 39 is larger than the number of the first air flow paths 38 and the opening area of the second air flow paths 39 is larger than the opening area of the first air flow paths 38, one second There are cases where a large number of adjacent first air flow paths 38 are connected by the air flow path 39, and the cartridge 14A cannot be provided with a large number of fine air flow paths 38, 39, but the second air flow path 39. Is smaller than that of the first air flow path 38, and the opening area of the second air flow path 39 is smaller than that of the first air flow path 38. The air flow paths 38 are not connected to each other, and a large number of fine air flow paths 38 and 39 can be stretched around the cartridge 14A.

  The longitudinal length L1 of the first air flow path 38 is in the range of 3 to 30 cm, preferably in the range of 5 to 15 cm. If the length dimension L1 of the first air flow path 38 is less than 3 cm, the air flow time in the air flow paths 38 and 39 cannot be increased, and the air contact time with respect to the cylindrical portion 37 (activated carbon) is increased. I can't. In the cartridge 14A, the longitudinal length L1 of the first air flow path 38 is in the above-described range, and the air flow time in the air flow paths 38 and 39 can be lengthened. Since the contact time of air can be lengthened, the odor contained in the air can be sufficiently adsorbed to the cylindrical portion 37, and the odor contained in the air can be reliably removed.

The number of first air flow paths 38 per 1 cm ² on the upper and lower end surfaces 31 and 32 of the deodorizing cartridge 14A is in the range of 30 to 50, preferably in the range of 35 to 45. If the number of the first air flow paths 38 per 1 cm ² of the upper and lower end surfaces 31 and 32 is less than 30, the number of the air flow paths 38 is small, and a predetermined amount of air cannot be brought into contact with the cylindrical portion 37 (activated carbon). The odor removal efficiency of the cartridge 14A is reduced. Note that if the number of first air flow paths 38 per 1 cm ² of the upper and lower end surfaces 31 and 32 exceeds 50, it is difficult to maintain the strength of the cartridge 14A, and the cartridge 14A may be damaged by impact. Since the number of the first air flow paths 38 per 1 cm ² on the upper and lower end surfaces 31 and 32 of the cartridge 14A is in the above range, a predetermined amount of air can be brought into contact with the cylindrical portion 37 (activated carbon), The contained odor can be sufficiently adsorbed to the cylindrical portion 37, and the odor contained in the air can be reliably removed. Further, since the cartridge 14A can maintain its strength, it can withstand a slight impact, and the cartridge 14A can be prevented from being inadvertently damaged.

Area S1 of the upper end surface 31 of the cartridge 14A located air inlet 40 side of the first air passage 38 (one end face) is in the range of 9～400Cm ^2, preferably in the range of 16～100Cm ^2, the area S2 of the lower end surface 32 of the cartridge 10A (the other end face) is located in the air outlet 41 side of the first air flow path 38 is in the range of 9～400Cm ^2, preferably in the range of 16~100cm ^2. When the areas S1 and S2 of the upper end surface 31 and the lower end surface 32 are less than 9 cm ² , the number of the first air flow paths 38 in the cartridge 14A decreases, and the odor removal efficiency of the cartridge 14A decreases. The cartridge 14A has the areas S1 and S2 of the upper end surface 31 and the lower end surface 32 in the above range, and allows a predetermined amount of air to flow through a sufficient number of the first air flow paths 38 to the cylindrical portion 37 (activated carbon). Since it can be contacted, the odor contained in the predetermined amount of air can be sufficiently adsorbed to the cylindrical portion 37 and the odor contained in the air can be reliably removed.

  An example of the procedure for making the deodorizing cartridge 14A of FIG. 4 is as follows. First, a cartridge 14A (activated carbon honeycomb) in which a cylindrical portion 37 having a honeycomb-shaped first air flow path 38 is formed is manufactured. The cartridge 14A having the cylindrical portion 37 can be made by existing extrusion molding using activated carbon powder or activated carbon fiber as a main raw material. Wood activated carbon, coconut activated carbon, and coal activated carbon can be used as the activated carbon. After making the cartridge 14A in which the cylindrical portion 37 (first air flow path 38) is formed, the first side 33 to the third side 35 of the cartridge 14A is used (or from the third side 35) using a drill. A second air flow path 39 that extends straight (toward the first side surface 33) is perforated. The second air flow passages 39 are formed in a line at predetermined equal intervals in the vertical direction and the horizontal direction, but may be formed at random at predetermined intervals in the vertical direction and the horizontal direction.

  After perforating the second air flow path 39, the open end (perforated hole) of the air flow path 39 that opens to the first side face 33 and the open end (perforated hole) of the air flow path 39 that opens to the third side face 35 Occlude. These open ends are blocked when a molten synthetic resin (which may include activated carbon powder) is applied to the first side surface 33 and the third side surface 35 and the side surfaces 33 and 35 are covered with a cured synthetic resin, or When the adhesive tape is applied to the first side surface 33 and the third side surface 35 and the side surfaces 33 and 35 are covered with the adhesive tape, or the side surfaces 33 and 35 are made of a pre-molded cylindrical plastic outer frame material. There are cases where it is coated.

  In order to close the air outlets 41 of some of the first air passages 38 among the first air passages 38, a synthetic resin melted by applying a molten synthetic resin to a part of the lower end surface 32 of the cartridge 14A and curing. When covering the lower end surface 32 and closing the air outlets 41 of some of the first air flow paths 38, or attaching an adhesive tape to a part of the lower end surface 32 of the cartridge 14A, 32 may be covered, and the air outlets 41 of some of the first air flow paths 38 may be closed.

  In the deodorizing cartridge 14 </ b> A, as shown in FIG. 6, the first air flow path 38 and the second air flow path 39 are connected in the cylindrical portion 37, and the adjacent first air flow paths 38 are connected to the second air flow path 39. It is connected via. The air flowing in from the air inlet 40 flows through the first air flow path 38 and flows from the air flow path 38 into the second air flow path 39 as shown by an arrow L4 in FIG. After flowing through the flow path 39 and flowing again into the other first air flow path 38 from the second air flow path 39, the air flow path 38 is flowed through.

  The air flowing through the first and second air flow paths 38 and 39 is turbulent at the intersection of the first air flow path 38 and the second air flow path 39 to become vortex flow or turbulence. The flow becomes air resistance and the flow is slowed down, and the flow rate of air in the cartridge 14A is reduced. Further, the air outlets 41 of some of the first air passages 38 are closed at the lower end surface 32 of the cartridge 14 </ b> A, and the total area of the air outlets 41 of the first air passages 38 ( The total number) is smaller (less) than the total area (total number) of the air inlets 40, and the amount of air that can flow out of the air outlet 41 is less than the amount of air that can flow in from the air inlet 40. The flow of air flowing through the flow paths 38 and 39 slows down, and the flow rate of air in the cartridge 14A decreases.

  While the flow rate of air decreases from the air inlet 40 toward the air outlet 41, the air gradually approaches the air outlet 41 through the air flow paths 38 and 39 and flows out from the air outlet 41. . In the cartridge 14A, in the process in which air flows through the first and second air flow paths 38 and 39, the cylinder portion 37 (activated carbon) comes into contact with odor (including radioactive substances such as iodine and cesium) contained in the air. Adsorbed on activated carbon. The odor (including the radioactive substance adsorption function) contained in the air flowing out from the air outlet 41 through the first air passage 38 and the second air passage 39 is removed.

  In the deodorizing cartridge 14 </ b> A, a plurality of second air passages 39 having a predetermined length extending in the front-rear direction (second direction) through which air can flow through the first air passages 38 are formed in the cylindrical portions 37. The first air flow path 38 and the second air flow path 39 are connected to each other in the cylindrical portion 37, and the air flowing in from the air inlet 40 passes through the first air flow path 38 and the second air flow path 39. The air flowing in from the air inlet 40 of the first air flow path 39 flows not only through the first air flow path 38 but also through the second air flow path 39 and from the second air flow path 39. It flows into the other first air flow path 38, further flows through the second air flow path 39, and flows into the other first air flow path 38.

The cylindrical portion 37 has a first air flow path 38 having a predetermined length through which air can flow. In addition to the first air flow path 38, a plurality of second air flow paths 39 and third air flow paths 42 having a predetermined length through which air can flow are formed in the cylindrical portions 37. The first air channel 38 has a honeycomb shape with a regular hexagonal cross section, and extends in the longitudinal direction (first direction) in parallel with each other. The first air flow path 38 has an air inlet 40 that opens at one end (the upper end surface 31 of the cartridge 14B) and an air outlet 41 that opens at the other end (the lower end surface 32 of the cartridge 14B). It penetrates between the upper and lower end surfaces 31 and 32 of 14B.

  At the lower end surface 32 of the deodorizing cartridge 14B, the air outlets 41 of some of the first air passages 38 of the first air passages 38 are closed, as in FIG. The air outlet 41 is opened (in FIG. 5). Therefore, the total number of air outlets 41 is smaller than the total number of air inlets 40. The total number of air outlets 41 is adjusted to a range of ½ to 1/5 of the total number of air inlets 40.

  The second air flow path 39 is spaced in parallel in the vertical direction and the horizontal direction, and extends in the front-rear direction (first crossing direction) intersecting the first air flow path 38. The second air channel 39 has a circular cross-sectional shape. The second air flow path 39 has an open end (air outlet) that opens to the first side surface 33 closed, and an open end (air outlet) that opens to the third side surface 35 closed. The second air flow path 39 is closed at the open ends of the first and third side surfaces 33 and 35 of the cartridge 14B, does not penetrate the first side surface 33 and the third side surface 35, and the cartridge 14B It extends only inside. The number of the second air passages 39 is smaller than the number of the first air passages 38, and the opening area thereof is smaller than the opening area of the first air passages 38.

The third air flow path 39 has a circular cross-sectional shape. The third air flow path 39 has an opening end (air outlet) opened on the second side surface 34 of the cartridge 14B closed, and an opening end (air outlet) opened on the fourth side surface 36 of the cartridge 14B closed. Yes. The third air flow path 42 is closed at the open ends of the second side surface 34 and the fourth side surface 36 of the cartridge 14B, does not penetrate the second side surface 34 and the fourth side surface 36, and the cartridge 14B It extends only inside. The number of the third air passages 42 is smaller than the number of the first air passages 38, and the opening area thereof is smaller than the opening area of the first air passage 38. The number of the third air passages 42 is substantially the same as the number of the second air passages 39, and the opening area thereof is substantially the same as the opening area of the second air passage 39.

  The first to third air flow paths 38, 39, and 42 intersect with each other so that they are substantially orthogonal to each other. The first to third air flow paths 38, 39, and 42 are, as indicated by a one-dot chain line in FIG. 10, a center line L2 of the first air flow path 38 and a center line of the second air flow path 39 inside the cartridge 14B. L3 and the center line L5 of the third air flow path 42 intersect at the centers of the air flow paths 38, 39, and 42. Therefore, in the first to third air flow paths 38, 39, 42, the first air flow path 38 and the second air flow path 39 intersect so as to be substantially orthogonal to each other, and the second air flow path 38 and the third air flow path 38 The air flow path 42 intersects so as to be substantially orthogonal, and the third air flow path 42 and the first air flow path 38 intersect so as to be substantially orthogonal.

The longitudinal length L1 of the first air flow path 38 in the deodorizing cartridge 14B, the number of the first air flow paths 38 per 1 cm ² on the upper and lower end surfaces 31 and 32 of the cartridge 14B, the air flow in the first air flow path 38 The area of the upper end surface 31 (one end portion) of the cartridge 14B located on the inlet 40 side and the area of the lower end surface 32 (other end surface) of the cartridge 14B located on the air outlet 41 side of the first air flow path 38 are shown in FIG. These are the same as those of the cartridge 14A.

In the deodorizing cartridge 14B, the longitudinal length L1 of the first air flow path 38 is in the above range, and the number of the first air flow paths 38 per 1 cm ² on the upper and lower end surfaces 31 and 32 of the cartridge 14B is in the above range. In addition, the area of the upper end surface 31 and the lower end surface 32 of the cartridge 14B is in the above range, and a predetermined amount of air is passed through a sufficient number of the first air flow paths 38 and the second and third air flow paths 39, 42. Since it can be made to flow and contact with the cylinder part 37 (activated carbon), the odor contained in a predetermined amount of air can be sufficiently adsorbed to the cylinder part 37 (activated carbon) and the odor contained in the air is surely secured. Can be removed.

  An example of the procedure for making the deodorizing cartridge 14B of FIG. 8 is as follows. First, a cartridge 14B (activated carbon honeycomb) in which a cylindrical portion 37 having a honeycomb-shaped first air flow path 38 is formed is manufactured. The cartridge 14B having the cylindrical portion 37 can be made by an existing extrusion molding using activated carbon powder or activated carbon fiber as a main raw material, similarly to that of FIG. After making the cartridge 14B in which the cylindrical portion 37 (the first air flow path 38) is formed, using the drill, the cartridge 14B moves from the first side surface 33 toward the third side surface 35 (or from the third side surface 35). The second air flow path 39 extending straightly toward the first side surface 33 is pierced, and the drill is used to move from the second side surface 34 of the cartridge 14B toward the fourth side surface 36 (or the fourth side surface 36).

  At the time of drilling the second air flow path 39 and the third air flow path 42, the air flow paths 39, 42 are drilled so as to be connected (crossed) to each other. The second air flow passages 39 are formed in a line at predetermined equal intervals in the vertical direction and the horizontal direction, but may be formed at random at predetermined intervals in the vertical direction and the horizontal direction. The third air flow paths 42 are formed in a row at predetermined equal intervals in the vertical direction and the front-rear direction, but may be randomly formed at predetermined intervals in the vertical direction and the front-rear direction.

  After perforating the second air flow path 39 and the third air flow path 42, the opening end (perforated hole) of the air flow path 39 that opens to the first side face 33 and the air flow path 39 that opens to the third side face 35 The open end (perforated hole) is closed, and the open end (perforated hole) of the air flow path 42 that opens to the second side surface 34 and the open end (perforated hole) of the air flow path 42 that opens to the fourth side surface 36. ). These open ends are blocked by applying a melted synthetic resin (which may include activated carbon powder) to the first to fourth side surfaces 33 to 36 and covering the first to fourth side surfaces 33 to 36 with the cured synthetic resin. If the adhesive tape is applied to the first to fourth side surfaces 33 to 36 and the first to fourth side surfaces 33 to 36 are covered with the adhesive tape, or a pre-molded cylindrical plastic outer frame In some cases, the first to fourth side surfaces 33 to 36 are covered with a material. The procedure for closing the air outlets 41 of some of the first air passages 38 is the same as that of the cartridge 14A of FIG.

  In the deodorizing cartridge 14 </ b> B, as shown in FIG. 9, the first air flow path 38 and the second air flow path 39 are connected in the cylindrical portion 37, and the second air flow path 39 and the third air flow path 42 are connected. At the same time, the third air flow path 42 and the first air flow path 38 are connected, and the adjacent first air flow paths 38 are connected to each other via the second and third air flow paths 39 and 42. The air flowing in from the air inlet 40 flows through the first air flow path 38 as shown by an arrow L4 in FIG. 10, and the second air flow path 39 and the third air flow from the air flow path 38. After flowing into the flow path 42 and flowing through the air flow paths 39, 42 and again flowing from the second air flow path 39 and the third air flow path 42 into the other first air flow paths 38, Circulate.

  The air flowing through the first to third air flow paths 38, 39, 42 is turbulent at the intersections of the first to third air flow paths 38, 39, 42, resulting in vortex flow or turbulence. The turbulent flow becomes air resistance, the flow of which slows down, and the flow rate of air in the cartridge 14B decreases. Further, the air outlet 41 of some of the first air passages 38 is closed at the lower end surface 32 of the cartridge 14 </ b> B, and the total area of the air outlets 41 of the first air passages 38 ( The total number) is smaller (less) than the total area (total number) of the air inlets 40, and the amount of air that can flow out of the air outlet 41 is less than the amount of air that can flow in from the air inlet 40. The flow of air flowing through the flow paths 38, 39, 42 is slowed down, and the flow rate of air in the cartridge 14B is reduced.

  While the flow velocity of the air decreases from the air inlet 40 toward the air outlet 41, the air gradually approaches the air outlet 41 through the air flow paths 38, 39, 42, and the air flows from the air outlet 41 to the outside. leak. In the cartridge 14B, in the process in which air flows through the first to third air flow paths 38, 39, and 42, the cylinder portion 37 (activated carbon) is contacted, and odors (including radioactive substances) contained in the air are adsorbed on the activated carbon. Is done. The odor (including radioactive material) contained in the air flowing out from the air outlet 41 through the first to third air flow paths 38, 39, 42 is removed.

  In the deodorizing cartridge 14 </ b> B, a plurality of second air flow paths 39 having a predetermined length extending in the front-rear direction (first crossing direction) through which air can flow through the first air flow path 38 are formed in the cylindrical portions 37. And a plurality of third air passages 42 of a predetermined length extending in a lateral direction (second crossing direction) through which air can flow across the first and second air passages 38, 39. The first air flow path 38, the second air flow path 39, and the third air flow path 42 are connected to each other in the cylindrical portions 37, and the air flowing in from the air inlet 40 is first to first in the cylindrical portions 37. Since the three air flow paths 38, 39, and 42 are passed, the air flowing in from the air inlet 40 of the first air flow path 38 is not only the first air flow path 38, but also the second air flow path 39 and the second air flow path 38. While passing through the three air flow paths 42, the second air flow path 39 and the third air flow path 42 are provided. It flows into the first air channel 38 Luo other, further flows through the second air passage 39 and the third air passage 42 flows into the first air channel 38 of the other.

FIG. In FIG. 11, the vertical direction is indicated by an arrow A, the front-rear direction (first crossing direction) is indicated by an arrow B, and the horizontal direction (second crossing direction) is indicated by an arrow C. In FIGS. 12 and 13, three cylindrical portions 37 are illustrated, but there are other cylindrical portions adjacent to the cylindrical portions 37. The cartridge 14C is different from that shown in FIG. 8 in that the second air flow path 39 and the third air flow path 42 are not directly connected but connected via the first air flow path 38. 8 is the same as that of the cartridge 14B in FIG. 8, and therefore, the same reference numerals as those in FIG. 8 are given, and the explanation of FIG.

  As shown in FIG. 11, the deodorizing cartridge 14 </ b> C is molded in a rectangular column shape that is long in the vertical direction. The cartridge 14C has an upper end surface 31 (one end surface) and a lower end surface 32 (other end surface), and first to fourth side surfaces 33 to 36. The cartridge 14C is formed with a plurality of cylindrical portions 37 having a regular hexagonal honeycomb shape and extending in the vertical direction. The cylindrical portions 37 are made of activated carbon. In addition to the first air flow path 38 penetrating between the upper and lower end surfaces 31, 32 of the cartridge 14C, a plurality of second air flow paths 39 having a predetermined length through which air can flow are provided in the cylindrical portions 37 of the cartridge 14C. And the 3rd air flow path 42 is formed. At the lower end surface 32 of the cartridge 14C, the air outlets 41 of some of the first air passages 38 of the first air passages 38 are closed, as in FIG. The outflow port 41 is open | released (FIG. 5 assistance). The total number of the air outlets 41 is smaller than the total number of the air inlets 40 and is adjusted to a range of ½ to 1/5 of the number of the air inlets 40.

  The first air flow path 38 and the second air flow path 39 intersect with each other so that they are substantially orthogonal to each other. The first air flow path 38 and the second air flow path 39 are the center line L2 of the first air flow path 38 and the center of the second air flow path 39 inside the cartridge 14C, as shown by a one-dot chain line in FIG. The line L3 intersects at the center of the air flow paths 38 and 39. The first air flow path 38 and the third air flow path 42 intersect with each other so that they are substantially orthogonal to each other. The first air flow path 38 and the third air flow path 42 are the center line L2 of the first air flow path 38 and the center of the third air flow path 42 inside the cartridge 14C, as shown by a one-dot chain line in FIG. The line L5 intersects at the center of the air flow paths 38 and 42. The second air flow path 39 and the third air flow path 42 are not directly connected to each other but are connected via the first air flow path 38.

  In the deodorizing cartridge 14C, the number of the second air passages 39 is smaller than that of the first air passages 38, and the opening area of the second air passages 39 is smaller than that of the first air passages 38. The plurality of adjacent first air flow paths 38 are not connected by the second air flow path 39, and a large number of fine air flow paths 38, 39 can be stretched around the cartridge 14C. In addition, since the number of the third air passages 42 is smaller than that of the first air passages 38 and the opening area of the third air passages 42 is smaller than that of the first air passages 38, one first air passage 42 is provided. The adjacent first air flow paths 38 are not connected to each other by the three air flow paths 42, and a large number of fine air flow paths 38, 42 can be stretched around the cartridge 14C.

These are the same as those of the cartridge 14A.

In the deodorizing cartridge 14C, the longitudinal length L1 of the first air flow path 38 is in the above range, and the number of the first air flow paths 38 per 1 cm ² on the upper and lower end surfaces 31 and 32 of the cartridge 14C is in the above range. In addition, the area of the upper end surface 31 and the lower end surface 32 of the cartridge 14C is in the above range, and a predetermined amount of air is passed through a sufficient number of the first air flow paths 38 to be brought into contact with the cylindrical portion 37 (activated carbon). Therefore, the odor contained in the predetermined amount of air can be sufficiently adsorbed by the cylindrical portion 37 (activated carbon), and the odor contained in the air can be reliably removed.

  An example of the procedure for making the deodorizing cartridge 14C in FIG. 11 is the same as the procedure for making the deodorizing cartridge 14C in FIG. 8, but when the second air passage 39 and the third air passage 42 are perforated, the air passage 39 , 42 are alternately drilled so that they do not connect (do not cross) each other. In the cartridge 14 </ b> C, as shown in FIG. 12, the first air flow path 38 and the second air flow path 39 are connected in the cylindrical portion 37, and the adjacent first air flow paths 38 connect the second air flow path 39. The first air flow path 38 and the third air flow path 42 are connected to each other, and the adjacent first air flow paths 38 are connected to each other via the third air flow path 42.

  The air flowing in from the air inlet 40 flows through the first air flow path 38 and flows into the second air flow path 39 from the first air flow path 38 as indicated by an arrow L4 in FIG. After flowing through the air flow path 39 and flowing again into the other first air flow path 38 from the second air flow path 39, the first air flow path 38 is flowed through. In addition, after flowing into the third air flow path 42 from the first air flow path 38, flowing through the air flow path 42, and flowing into the other first air flow path 38 from the third air flow path 42 again, One air flow path 38 flows.

  The air flowing through the first and second air flow paths 38 and 39 is turbulent at the intersection of the first air flow path 38 and the second air flow path 39 to become a vortex or turbulent flow. Becomes air resistance and the flow is slowed down, and the flow rate of air in the cartridge 14C decreases. The air flowing through the first and third air flow paths 38 and 42 is turbulent at the intersection of the first air flow path 38 and the third air flow path 42 to become a vortex flow or a turbulent flow. Becomes air resistance and the flow is slowed down, and the flow rate of air in the cartridge 14C decreases. Further, the air outlets 41 of some of the first air passages 38 are closed at the lower end surface 32 of the cartridge 14 </ b> C, and the total area of the air outlets 41 of these first air passages 38 ( The total number) is smaller (less) than the total area (total number) of the air inlets 40, and the amount of air that can flow out of the air outlet 41 is less than the amount of air that can flow in from the air inlet 40. The flow of air flowing through the flow paths 38, 39, 42 is slowed down, and the flow rate of air in the cartridge 14C is reduced.

  While the flow velocity of the air decreases from the air inlet 40 toward the air outlet 41, the air gradually approaches the air outlet 41 through the air flow paths 38, 39, 42, and the air flows from the air outlet 41 to the outside. leak. In the cartridge 14C, in the process in which air flows through the first to third air flow paths 38, 39, and 42, the cylinder portion 37 (activated carbon) is contacted, and odors (including radioactive substances) contained in the air are adsorbed on the activated carbon. Is done. The odor (including radioactive material) contained in the air flowing out from the air outlet 41 through the first to third air flow paths 38, 39, 42 is removed.

  The procedure for using this deodorizing apparatus 10A will be described as follows. First, one of the deodorizing cartridges 14A, 14B, and 14C is stored inside the storage case 11. The cartridges 14 </ b> A, 14 </ b> B, and 14 </ b> C are put into the case 11 from the top opening 17. The cartridges 14 </ b> A, 14 </ b> B, and 14 </ b> C are housed inside the case 11 with the upper end surface 31 facing down and the lower end surface 32 facing upward. When the cartridges 14A, 14B, and 14C are inserted into the case 11, the cartridges 14A, 14B, and 14C are positioned immediately above the blower fan 13, and the upper end surfaces 31 of the cartridges 14A, 14B, and 14C are in contact with the flange 21, so 14B and 14C are supported by the flange 21.

  The vertical length of the storage case 11 is larger than the length L1 of the deodorizing cartridges 14A, 14B, and 14C, and the volume of the case 11 is large enough to accommodate the cartridges 14A, 14B, and 14C. The cartridges 14 </ b> A, 14 </ b> B, and 14 </ b> C are entirely accommodated in the case 11. The first air flow paths 38 of the cylindrical members 37 of the cartridges 14A, 14B, and 14C extend vertically between the lower portion and the upper portion of the case 11 (between the lower end portion 18 and the upper end portion 20 of the peripheral wall 15). The air inlet 40 of the first air passage 38 is located immediately above the fan 13 and faces the fan 13, and the air outlet 41 of the air passage 38 is located on the top opening 17 side. After the cartridges 14A, 14B, and 14C are housed inside the case 11, the deodorizing apparatus 10A is placed on a table, desk, floor, hallway, toilet, etc., and the ON / OFF switch 27 is turned on.

  When the switch 27 is turned on, electricity is sent from the solar panel 26 (or battery) to the DC motor 29, and the propeller 30 is rotated by the rotation of the shaft of the DC motor 29. When the propeller 30 rotates, as indicated by an arrow N3 in FIG. 1, an air flow is generated from the lower part to the upper part of the case 11, and the air flows into the case 11 from these through holes 22, and the air flows into the cartridge. 14A, 14B, and 14C flow into the air flow path 38 from the air inlet 40 of the first air flow path 38 of the cylindrical member 37.

  When the deodorizing cartridge 14 </ b> A is used, the air flowing in from the air inlet 40 flows through the first air flow path 38 and also flows from the air flow path 38 into the second air flow path 39 and flows through the air flow path 39. The air flows and flows again from the second air flow path 39 to the other first air flow path 38, and then flows through the air flow path 38. In the process in which the air flows through the first and second air flow paths 38 and 39, the cylinder portion 37 (activated carbon) comes into contact, and the odor (including radioactive material) contained in the air is adsorbed by the activated carbon. The purified air flows out of the cartridge 14A from the air outlet 41 of the first air flow path 38. The clean air that has flowed out of the cartridge 14 </ b> A is sent from the top opening 17 of the case 11 to the outside of the case 11. After the cartridge 14A has been used for a predetermined period, the cartridge 14A is removed from the case 11 and a new cartridge 14A is stored in the case 11.

  When the deodorizing cartridge 14B or the deodorizing cartridge 14C is used, the air flowing in from the air inlet 40 flows through the first air flow path 38 and from the air flow path 38 to the second air flow path 39 or the third air flow. The air flows into the passage 42 and flows through the air flow paths 39, 42, and again flows into the other first air flow path 38 from the second air flow path 39 and the third air flow path 42, and then passes through the air flow path 38. Shed. In the process in which air flows through the first to third air flow paths 38, 39, and 42, the cylinder portion 37 (activated carbon) comes into contact, and odors (including radioactive substances) contained in the air are adsorbed by the activated carbon. The purified air flows out of the cartridges 14B and 14C from the air outlet 41 of the first air flow path 38. The clean air that has flowed out of the cartridges 14 </ b> B and 14 </ b> C is sent from the top opening 17 of the case 11 to the outside of the case 11. After the cartridges 14B and 14C have been used for a predetermined period, the cartridges 14B and 14C are removed from the case 11 and new cartridges 14B and 14C are stored in the case 11.

In the deodorizing apparatus 10A, the rotational speed of the blower fan 13 (propeller 39) is in the range of 60 to 480 r / min, and the flow velocity of the air flowing through the first air flow path 38 of the cartridges 14A, 14B, and 14C is 0.01 to 0. It is adjusted to the range of 1 m ³ / sec. When the rotational speed of the fan 13 exceeds 480 r / min and the flow velocity of the air flowing through the first air flow path 38 exceeds 0.1 m ³ / sec, the air flow speed in the air flow paths 38, 39, 42 increases. Since the air passes through the air flow paths 38, 39, and 42 in a short time, the contact time of the air with the tubular member 37 (activated carbon) is shortened, and the odor contained in the air can be sufficiently adsorbed by the activated carbon. Can not. In the deodorizing apparatus 10A, the rotational speed of the blower fan 13 is in the above range, the flow velocity of the air flowing through the first air flow path 38 is in the above range, and the air slowly flows through the air flow paths 38, 39, and 42. The contact time of air with respect to the tubular member 37 (activated carbon) can be lengthened, and the odor contained in the air can be sufficiently adsorbed to the activated carbon.

  The deodorizing apparatus 10 </ b> A has a first air flow path 38 extending in the vertical direction from the upper end surface 31 of the cartridge 14 </ b> A, 14 </ b> B, 14 </ b> C toward the lower end surface 32 of the air taken into the case 11 from the through hole 22 by the blower fan 13. The air can be reliably brought into contact with the tubular member 37 (activated carbon) by flowing air through the air flow paths 38, 39, and 42 of the tubular member 37 made of activated carbon. The contained odor can be sufficiently adsorbed on the activated carbon. Since the deodorizing apparatus 10A can reduce the flow rate of the air flowing through the air flow paths 38, 39, 42, the air flow time in the air flow paths 38, 39, 42 can be made sufficiently long. In addition, the contact time of air with respect to the cylindrical portion 37 (activated carbon) can be made sufficiently long, and the odor contained in the air can be reliably removed.

  The deodorization apparatus 10A can remove odor contained in the air reliably by the cylindrical portion 37 (activated carbon), can produce clean air, and can send clean air to the outside from the top opening 17 of the case 11. it can. In the deodorizing apparatus 10A, the cartridges 14A, 14B, and 14C are positioned immediately above the blower fan 13 so that the air taken into the inside of the case 11 through the through holes 22 is supplied to the air flow paths 38, 39, and 42 of the cylindrical members 37. Since it can be made to flow uniformly to all, the deodorizing function of cartridge 14A, 14B, 14C can be utilized to the maximum, and the deodorizing efficiency in apparatus 10A can be improved.

  The procedure for using the deodorizing apparatus 10B will be described as follows. As in the apparatus 10A of FIG. 1, first, one of the deodorizing cartridges 14A, 14B, and 14C is stored inside the storage case 11. The cartridges 14 </ b> A, 14 </ b> B, and 14 </ b> C are put into the case 11 from the top opening 17. When the cartridges 14A, 14B, and 14C are inserted into the case 11, the cartridges 14A, 14B, and 14C are positioned immediately above the blower fan 13, and the upper end surfaces 31 of the cartridges 14A, 14B, and 14C are in contact with the second flange 21, and the cartridge 14A, 14B, and 14C are supported by the flange 21. The first air flow paths 38 of the cylindrical members 37 of the cartridges 14A, 14B, and 14C extend vertically between the lower portion and the upper portion of the case 11 (between the lower end portion 18 and the upper end portion 20 of the peripheral wall 15).

  As in the case of the deodorizing apparatus 10A of FIG. 1, the length dimension of the storage case 11 in the vertical direction is larger than the length dimension L1 of the cartridges 14A, 14B, 14C, and the volume of the case 11 is the cartridge 14A, 14B, The size of the cartridge 14 </ b> C is adjusted so that the entire cartridge 14 </ b> C can be accommodated, and the entire cartridge 14 </ b> A, 14 </ b> B, 14 </ b> C is accommodated in the case 11. Next, the sheet 45 is inserted into the storage case 11 through the slit 43 while holding the knob 47 of the fragrance sheet 45. When the fragrance sheet 45 is inserted into the case 11, the peripheral edge 46 of the sheet 45 is supported by the first flange 44, and the sheet 45 is positioned above the lower end surface 32 of the cartridges 14A, 14B, and 14C. The air inlet 40 of the first air flow path 37 of the cylindrical portion 37 is located immediately above the fan 13 and faces the fan 13, and the air outlet 41 of the first air flow path 37 is located on the top opening 17 side.
