Detailed Implementation

[0032] The embodiments for carrying out the invention will be described with reference to the accompanying drawings. Furthermore, in the drawings, identical or equivalent parts are labeled with the same reference numerals. Repetitive descriptions of these parts are appropriately simplified or omitted.

[0033] Implementation method 1.

[0034] Figure 1 This is a diagram showing the deodorization device in Embodiment 1.

[0035] like Figure 1 As shown, for example, deodorization device 1 is used in an elevator.

[0036] The hoistway 100 runs through all floors of a building (not shown). The elevator car 101 is located inside the hoistway 100. The car 101 rises or falls inside the hoistway 100. The rising or falling movement of the car 101 is controlled by a control panel (not shown).

[0037] The deodorization device 1 includes a storage box 2, a fan 3, and a deodorizer 10. For example, the deodorization device 1 is installed on the upper part of the car 101.

[0038] For example, the storage box 2 is a rectangular box. The storage box 2 has a pair of lids 2a on opposite sides. The storage box 2 has a controller 2b. The storage box 2 is disposed on the upper surface of the car 101. The storage box 2 is configured such that one of the lids 2a faces the side wall of the hoistway 100. For example, the storage box 2 is configured such that, when viewed from the vertical direction, one of the lids 2a protrudes from the car 101. For example, the storage box 2 is electrically connected to the control panel. The storage box 2 obtains control information of the car 101 from the control panel.

[0039] For example, the pair of lids 2a are each hinged and designed to open and close freely. For example, the pair of lids 2a open and close a portion of each of the pair of sides of the storage box 2.

[0040] Controller 2b is electrically connected to the control panel. Controller 2b obtains control information from the control panel. For example, controller 2b controls the opening and closing of a pair of lids 2a.

[0041] For example, controller 2b uses control information to control the opening and closing of a pair of car covers 2a. When the car 101 is rising or falling, the pair of car covers 2a open according to the control of controller 2b. When the car 101 is stopped, the pair of car covers 2a close according to the control of controller 2b. When the car 101 is stopped, the pair of car covers 2a are closed.

[0042] The fan 3 has blades 3a, an intake 3b, and an outlet 3c. The fan 3 is located on the upper surface of the car 101. The fan 3 is positioned to the side of the storage box 2. The fan 3 generates airflow from the intake 3b toward the outlet 3c by rotating the blades 3a. The fan 3 draws in gas from the intake 3b and blows gas out from the outlet 3c.

[0043] The suction port 3b is connected to the other of a pair of lids 2a.

[0044] The blowout outlet 3c is connected to the upper surface of the car 101. The blowout outlet 3c is also connected to the interior of the car 101.

[0045] The deodorizer 10 is located inside the storage box 2. The deodorizer 10 imparts deodorizing components to the gas passing through it.

[0046] During the lifting and lowering of the car 101, the deodorizing device 1 blows gas with deodorizing components into the interior of the car 101.

[0047] For example, when the car 101 is ascending, the controller 2b opens both of the two doors 2a. With the doors 2a open, the fan 3 draws in air from inside the storage box 2 via the intake 3b. Inside the storage box 2, the fan 3 generates airflow from one door 2a to the other. This air passes through the interior of the deodorizer 10, which imparts deodorizing components. The fan 3 then blows this air out of the outlet 3c into the interior of the car 101.

[0048] For example, when the car 101 is stopped, the controller 2b closes the pair of doors 2a. For example, when the car 101 is stopped, the deodorizing device 1 stops blowing the deodorizing gas into the interior of the car 101.

[0049] Next, use Figure 2 The mechanism of the deodorizer 10 will be explained.

[0050] Figure 2 This is a diagram showing the deodorizer of the deodorizing device in Embodiment 1. Figure 2 (A) is a perspective view of an example of deodorizer 10. Figure 2 (B) is a cross-sectional view of the deodorizer 10. Figure 2 (C) is Figure 2 The Y-direction view in (B).

[0051] The deodorizer 10 includes a container 11, a deodorant 12, a screen 13, a first cover 14, a second cover 15, a cover shaft 16, and a drive motor 20.

[0052] For example, container 11 is cylindrical in shape. Container 11 has cavities inside. For example, container 11 has a pair of container openings 11a, a plurality of partition surfaces 11b, and a plurality of chambers 11c.

[0053] A pair of container openings 11a are respectively provided on a pair of opposite sides of the container 11. For example, the pair of container openings 11a are respectively provided on a pair of bottom surfaces in the container 11. For example, the pair of container openings 11a are respectively equivalent to the entirety of a pair of bottom surfaces in the container 11.

[0054] Multiple partition surfaces 11b are respectively disposed inside the container 11. The partition surfaces 11b are respectively disposed from one of a pair of container openings 11a to the other. For example, the partition surfaces 11b are respectively disposed perpendicular to the pair of container openings 11a. For example, the partition surfaces 11b are respectively disposed radially from the central axis of the cylinder of the container 11. The partition surfaces 11b divide the interior of the container 11. For example, there are 16 partition surfaces 11b. For example, the partition surfaces 11b divide the interior of the container 11 into 16 equal parts.

[0055] Each of the multiple chambers 11c represents a region within the container 11 that is divided by multiple partition surfaces 11b. Each chamber 11c has a columnar shape with a pair of container openings 11a as its base. For example, each of the multiple chambers 11c has a fan-shaped cross-section. For example, 16 chambers 11c are provided in the container 11.

[0056] For example, deodorant 12 is a deodorant impregnated with fragrance in porous resin beads. For example, the fragrance can be essential oil, or a substance obtained by diluting essential oil with a solvent. For example, the fragrance is a volatile deodorizing ingredient. For example, deodorant 12 contains multiple volatile deodorizing ingredients. These multiple volatile deodorizing ingredients each use fragrance to mask odors.

[0057] Each of the multiple chambers 11c is provided with a deodorant 12. Gas can pass freely through the interior of the deodorant 12. For example, the deodorant 12 allows gas to pass through its interior, thereby imparting a deodorizing component to the passing gas.

[0058] For example, multiple screens 13 have a mesh structure. Multiple screens 13 are respectively disposed at both ends of multiple chamber portions 11c. Multiple screens 13 allow gas to pass through. Multiple screens 13 respectively prevent deodorant 12 from leaking out of the multiple chamber portions 11c.

[0059] For example, the first cover 14 is formed in the shape of a disc. The first cover 14 has a first cover opening 14a. The first cover 14 is arranged opposite to one of a pair of container openings 11a. For example, the center of the disc of the first cover 14 is located on the extension line of the cylindrical axis of the container 11. For example, the side of the first cover 14 is opposite to one of the pair of container openings 11a.

[0060] For example, the first cover 14 is positioned on the upwind side of the container 11 in the airflow passing through the lid 2a (not shown). The first cover 14 is positioned to block one end of a chamber portion 11c that is not opposite to the opening 14a of the first cover. The first cover 14 is positioned to not block one end of a chamber portion 11c that is opposite to the opening 14a of the first cover. The first cover 14 isolates the multiple chamber portions 11c blocked by the first cover 14 from the gas outside the container 11.

[0061] For example, the first cover opening 14a is formed by cutting off a portion of the first cover 14. The first cover opening 14a has a shape formed by connecting the cross-sections of several of the plurality of chamber portions 11c. For example, the first cover opening 14a has a fan-shaped shape. For example, the first cover opening 14a is a fan-shaped opening formed by connecting the cross-sections of three of the plurality of chamber portions 11c. The first cover opening 14a has an area equal to the sum of the cross-sectional areas of two or more of the plurality of chamber portions 11c, but less than the total number of cross-sections. For example, the first cover opening 14a has an area equal to the area of ​​the combined cross-sections of three of the plurality of chamber portions 11c.

[0062] For example, the second cover 15 is formed in the shape of a disc. The second cover 15 has a second cover opening 15a. The second cover 15 is arranged opposite to the other of the pair of container openings 11a. For example, the center of the disc of the second cover 15 is located on the extension line of the cylindrical axis of the container 11. For example, the side of the second cover 15 is opposite to the other of the pair of container openings 11a.

[0063] For example, the first cover 14 is positioned on the leeward side of the container 11 in the airflow passing through the cover 2a. The second cover 15 is positioned to block the other end of one of the plurality of chambers 11c that is not opposite to the opening 15a of the second cover. The second cover 15 is positioned so as not to block the other end of one of the plurality of chambers 11c that is opposite to the opening 15a of the second cover. The second cover 15 isolates the plurality of chambers 11c blocked by the second cover 15 from the gas outside the container 11.

[0064] The second cover 15 is provided in a manner consistent with the plurality of chamber portions 11c opposite to the second cover opening 15a and the plurality of chamber portions 11c opposite to the first cover opening 14a.

[0065] For example, the second cover opening 15a is formed by cutting off a portion of the second cover 15. The second cover opening 15a has a shape formed by connecting the cross-sections of several of the plurality of chamber portions 11c. For example, the second cover opening 15a has a fan-shaped portion. For example, the second cover opening 15a is a fan-shaped portion formed by connecting the cross-sections of three of the plurality of chamber portions 11c. The second cover opening 15a has an area equal to the sum of the cross-sectional areas of two or more of the plurality of chamber portions 11c and less than the total number of them. For example, the second cover opening 15a has an area equal to the area of ​​the combined cross-sections of three of the plurality of chamber portions 11c.

[0066] For example, the cover shaft 16 has a rod-like shape. The cover shaft 16 is connected to the center of the first cover 14 in a manner synchronized with the rotation of the first cover 14. The cover shaft 16 is connected to the center of the second cover 15 in a manner synchronized with the rotation of the second cover 15. The cover shaft 16 rotates synchronously with the first cover 14 and the second cover 15. The cover shaft 16 rotates the first cover opening 14a and the second cover opening 15a by the same angle.

[0067] For example, the drive unit 20 includes a motor 21, a belt 22, and a cover controller 23. For example, the drive unit 20 is connected to the cover shaft 16. For example, the drive unit 20 rotates the cover shaft 16. The drive unit 20 moves the first cover 14 and the second cover 15 via the cover shaft 16. The drive unit 20 changes the relative positions of the first cover 14 and the second cover 15 with respect to the container 11. When the relative positions of the first cover 14 and the second cover 15 with respect to the container 11 change, the positions of the chambers 11c blocked by the first cover 14 and the second cover 15 among the plurality of chambers 11c change.

[0068] For example, motor 21 has a rotating shaft. Motor 21 causes the rotating shaft to generate rotational driving force.

[0069] For example, belt 22 is a loop belt. One end of belt 22 is wound around cover shaft 16 in a manner that allows it to move in response to the rotation of cover shaft 16. The other end of belt 22 is wound around the rotating shaft of motor 21 in a manner that allows it to move in response to the rotation of motor 21. For example, belt 22 transmits the rotational driving force of motor 21 to cover shaft 16.

[0070] The cover controller 23 is electrically connected to the motor 21. The cover controller 23 controls the operation of the motor 21. For example, the cover controller 23 drives the motor 21 at any speed. For example, the cover controller 23 causes the first cover 14 and the second cover 15 to rotate at any angle via the motor 21.

[0071] exist Figure 2 In the storage box 2 (not shown), gas passes through the interior of a plurality of chambers 11c that are not blocked by the first cover 14 or the second cover 15. Inside the plurality of chambers 11c, the deodorizer 10 imparts a deodorizing component to the gas. Hereinafter, the chamber 11c in which gas passes through is referred to as a "cell in use".

[0072] Next, use Figure 3 and Figure 4 An example of the process by which the chamber of the deodorizer 10 changes during use will be explained.

[0073] Figure 3 This is an X-direction view of the deodorizer of the deodorizing device in Embodiment 1. Figure 4 This is a diagram showing the X-direction view of the deodorizer in Embodiment 1, presented according to different times.

[0074] like Figure 3 As shown, for example, the deodorizer 10 has a plurality of chambers 11c, which are 16 in number. For example, in the deodorizer 10, three of the plurality of chambers 11c are chambers in use. The first cover opening 14a is located in a clockwise direction from the twelve o'clock position of a clock. Figure 3 The deodorizer 10 is in a state where no gas passes through. Figure 3 The state of the deodorizer 10 is defined as the initial state.

[0075] For example, the multiple chambers 11c are labeled a to p, with the twelve o'clock position as the reference. For example, the chamber located at the twelve o'clock position on a clock is chamber a. The chamber adjacent to the right of chamber a is chamber b. Similarly, chambers c to p are arranged sequentially in a clockwise direction.

[0076] For example, the first cover 14 and Figure 3 The second cover 15 (not shown) rotates clockwise at regular intervals by an angle equivalent to one of the multiple chamber sections 11c. For example, the first cover 14 and the second cover 15 rotate clockwise by 22.5 degrees every month.

[0077] The deodorant 12's deodorizing effect decreases over time. For example, deodorant 12 is categorized based on the duration of use. For example, if used for less than one month, deodorant 12 is considered "new." For example, if used for more than one month but less than two months, deodorant 12 is considered "old 1." For example, if used for more than two months, deodorant 12 is considered "old 2." For example, initially, the deodorant 12 in chambers a, b, and c is considered "new." Hereinafter, the deodorant 12 in chambers a to p is defined as deodorant 12a to deodorant 12p, respectively.

[0078] like Figure 4 As shown, for example, the deodorizer 10 changes the position of the chamber in use every month. Figure 4 (A) indicates the deodorizer 10 in its initial state. Figure 4 (B) indicates that the deodorizer 10 has been in its initial state for 1 month. Figure 4 (C) indicates that the deodorizer 10 has been in its initial state for 2 months. Figure 4 (D) indicates that the deodorizer 10 has been in its initial state for 3 months.

[0079] exist Figure 4 In (A), deodorant 12a, deodorant 12b and deodorant 12c are in a "new" state.

[0080] exist Figure 4 In (B), the first cover 14 and Figure 4 The second cover 15, not shown in the diagram, is rotated 22.5 degrees clockwise compared to its initial state. Chamber a is not in use. Chamber d is in use. Deodorants 12b and 12c are in the "old 1" state. Deodorant 12d is in the "new" state. The deodorizer 10 releases a gas containing a mixture of the deodorizing components from the "old 1" and "new" states.

[0081] exist Figure 4 In (C), the first cover 14 and the second cover 15 are... Figure 4 The state shown in (B) is rotated 22.5 degrees clockwise compared to the state shown in (B). Chamber b is not in use. Chamber e is in use. Deodorant 12c is in the "Old 2" state. Deodorant 12d is in the "Old 1" state. Deodorant 12e is in the "New" state. Deodorizer 10 releases a gas containing a mixture of deodorizing components from the "Old 2", "Old 1", and "New" states.

[0082] exist Figure 4 In (D), the first cover 14 and the second cover 15 are related to Figure 4 The state shown in (C) is rotated 22.5 degrees clockwise compared to the previous state. Chamber c is not in use. Chamber f is in use. Deodorant 12d is in the "Old 2" state. Deodorant 12e is in the "Old 1" state. Deodorant 12f is in the "New" state. Deodorizer 10 releases a gas containing deodorizing components from the "Old 2", "Old 1", and "New" states.

[0083] Afterward, the deodorizer 10 performs the same operation as described above every month. During the period of 13 months from the initial state, the deodorizer 10 releases a gas containing deodorizing components from the states of "Old 2", "Old 1" and "New".

[0084] After 14 months from the initial state, the chambers in use are chamber 0, chamber p, and chamber a. In chamber a, deodorant 12a is in the "old 1" state. Deodorizer 10 releases a gas containing a mixture of deodorizing components in the "old 2" and "old 1" states.

[0085] After more than 15 months from the initial state, the deodorizer 10 releases a gas mixed with the deodorizing components of the "old 2" state.

[0086] Next, use Figures 5 to 8 The changes in the deodorization effect of deodorizer 10 will be explained by comparing them with the same situation in deodorizer 50 of the existing structure.

[0087] Figure 5This is a diagram showing a conventional deodorizer, which is a comparative example of the deodorizing device in Embodiment 1. Figure 6 This is a diagram showing the change in the fragrance intensity of the deodorizing component in the deodorizing device of Embodiment 1. Figure 7 This is a graph showing the change in the ratio of fragrance intensity of the deodorizing components in the deodorizing device of Embodiment 1. Figure 8 This is a graph showing the change in the total fragrance intensity of the deodorizing components in the deodorizing device of Embodiment 1.

[0088] like Figure 5 As shown, for example, the deodorizer 50 of the conventional structure has a cylindrical shape. The deodorizer 50 contains a deodorizing agent 12 inside. The deodorizer 50 is similar to that of Embodiment 1. Figure 5 Compared to the deodorizer 10 (not shown), the deodorizer 50 does not have multiple chamber sections 11c, a first cover 14, and a second cover 15. The deodorizer 50 uses the entire internal deodorizing agent 12 to impart deodorizing components to the gas.

[0089] exist Figure 6 The diagram shows a graph representing the relationship between the fragrance intensity of the deodorizing components in the gas after passing through deodorizing device 1 and the elapsed time. Fragrance intensity is the perceived intensity of the fragrance of the deodorizing components. Fragrance intensity is positively correlated with the concentration of the deodorizing components in the gas. The unit of fragrance intensity is any unit [au].

[0090] The vertical axis represents the fragrance intensity of the deodorizing components in the gas after passing through deodorizing device 1. The unit of the vertical axis is any unit [au].

[0091] The horizontal axis represents the time elapsed since the initial state. The unit of the horizontal axis is any unit [au]. For example, the unit of the horizontal axis is 1 month.

[0092] For example, deodorant 12 comprises deodorizing component A and deodorizing component B. Deodorizing component A is a highly volatile component. Deodorizing component B is a less volatile component compared to deodorizing component A. For example, deodorant 12 exerts its deodorizing effect when the sum of the concentrations of deodorizing component A and deodorizing component B in the gas it comes into contact with is greater than a certain value. For example, deodorant 12 exerts its deodorizing effect when the ratio of the concentration of deodorizing component A to the concentration of deodorizing component B in the gas it comes into contact with is within a certain range.

[0093] The fragrance intensity imparted to the gas by deodorant 12 decreases over time. The fragrance intensity x(t) is represented by the following equation (1).

[0094] x(t)=A*exp(-t / ε) (1)

[0095] t is the time elapsed from the initial state. A is the initial intensity, representing the fragrance intensity in the initial state. ε is the decay coefficient inherent to each deodorizing ingredient. For example, the ε value of deodorizing ingredient A is twice the ε value of deodorizing ingredient B.

[0096] exist Figure 6 In the graph, the relationships shown by the deodorizer 10 of Embodiment 1 are depicted with solid lines. The thin lines in this solid line represent the relationship of deodorizing component A. The thick lines in this solid line represent the relationship of deodorizing component B.

[0097] In deodorizer 10, the fragrance intensity of deodorizing component A decreases from an initial value of 6. After one month from the initial state, the chamber in use is switched to another chamber. When the chamber in use is switched, the fragrance intensity of deodorizing component A increases. The sawtooth shape of the graph of deodorizing component A indicates the switching of the chamber in use. During the period from the initial state to more than 2 months but less than 14 months, the fragrance intensity of deodorizing component A remains within a certain range. After 14 months from the initial state, the fragrance intensity of deodorizing component A decreases.

[0098] In deodorizer 10, the fragrance intensity of deodorizing component B decreases from an initial value of 3. The fragrance intensity curve of deodorizing component B shows the same trend as that of deodorizing component A.

[0099] exist Figure 6 In the graph, the relationships shown by the existing deodorizer 50 are depicted using dashed lines or single-dot lines. The dashed line represents the relationship of the concentration of deodorizing component A. The single-dot line represents the relationship of the concentration of deodorizing component B. To ensure equal conditions, the airflow in the existing deodorizer 50 is set to 3 / 16 times the airflow in the deodorizer 10.

[0100] In deodorizer 50, the fragrance intensity of deodorizing component A decreases monotonically from an initial value of 6. Due to the different set airflow, this rate of decrease is slower than the rate of decrease in fragrance intensity of deodorizing component A in deodorizer 10.

[0101] In deodorizer 50, the fragrance intensity of deodorizing component B decreases monotonically from an initial value of 3. Due to the different set airflow, this rate of decrease is slower than the rate of decrease in fragrance intensity of deodorizing component B in deodorizer 10.

[0102] In deodorizer 50, after approximately 8 months from its initial state, the fragrance intensity of deodorizing component A is weaker than that of deodorizing component B.

[0103] exist Figure 7The figure shows a graph representing the relationship between the ratio of deodorizing components in the gas after passing through the deodorizing device 1 and the elapsed time.

[0104] The vertical axis represents the ratio A / B of the fragrance intensity of the gas after passing through deodorizing device 1. The unit of the vertical axis is any unit [au]. The fragrance intensity ratio A / B is the ratio of the fragrance intensity of deodorizing component A to the fragrance intensity of deodorizing component B.

[0105] For example, deodorant 12 works effectively when the ratio of fragrance intensity A to B in the exposed gas is within a certain range. This range is called the optimal component ratio. For example, the optimal component ratio is between 1.0 and 1.6.

[0106] The horizontal axis represents the time elapsed since the initial state. The unit of the horizontal axis is any unit [au]. For example, the unit of the horizontal axis is 1 month.

[0107] exist Figure 7 In the graph, the relationship shown by the deodorizer 10 of Embodiment 1 is depicted with a solid line. The sawtooth shape of the graph of the deodorizer 10 indicates the switching of chambers during use. The ratio of fragrance intensity represents the optimal component ratio during a period of more than 2 months but less than 14 months from the initial state.

[0108] exist Figure 7 In the graph, the relationship shown by the existing structure deodorizer 50 is depicted with a dashed line. To ensure equal conditions, the airflow in the existing structure deodorizer 50 is set to 3 / 16 times the airflow in the deodorizer 10.

[0109] In deodorizer 50, the fragrance intensity ratio A / B decreases monotonically from an initial value of 2. In deodorizer 50, the fragrance intensity ratio A / B falls below 1.0 after approximately 8 months from its initial state. When the fragrance intensity ratio A / B falls below 1, the fragrance produced by deodorant 12 becomes completely different from its initial state.

[0110] like Figure 7 As shown in the graph, deodorizer 10 provides a longer-lasting deodorizing effect compared to deodorizer 50. Deodorizer 10 maintains a consistent fragrance quality, thus ensuring a prolonged masking effect.

[0111] exist Figure 8 The diagram shows the relationship between the total fragrance intensity of the gas after passing through deodorizing device 1 and the elapsed time. Total fragrance intensity refers to the sum of the fragrance intensities of each deodorizing component.

[0112] The vertical axis represents the total fragrance intensity of the deodorizing components contained in the gas after passing through deodorizing device 1. The unit of the vertical axis is any unit [au].

[0113] For example, deodorant 12 works effectively when the total fragrance intensity in the exposed gas is within a certain range. This range is referred to as the optimal concentration in the car. For example, the optimal concentration in the car is between 2.5 and 5.0.

[0114] The horizontal axis represents the time elapsed since the initial state. The unit of the horizontal axis is any unit [au]. For example, the unit of the horizontal axis is 1 month.

[0115] exist Figure 8 In the graph, the relationship shown by the deodorizer 10 of Embodiment 1 is depicted with a solid line. The sawtooth shape of the graph of the deodorizer 10 indicates the switching of chambers during use. The total fragrance intensity represents the optimal concentration value in the car during a period of more than 2 months but less than 14 months from the initial state.

[0116] exist Figure 8 In the graph, the relationship shown by the existing structure deodorizer 50 is depicted with a dashed line. As cases X, Y, and Z, the airflow in the existing structure deodorizer 50 is set to 3 / 16, 2 / 16, and 1 / 16 times the airflow in the deodorizer 10, respectively.

[0117] In deodorizer 50, under condition X, the total fragrance intensity begins to decrease monotonically from an initial value of 9. Subsequently, after approximately 9 months from the initial state, the total fragrance intensity falls below 2.5.

[0118] In deodorizer 50, in cases Y or Z, the total fragrance intensity decreases gradually compared to case X. In cases Y or Z, the initial total fragrance intensity is weaker than that in case X. In case Y, the total fragrance intensity falls below 2.5 after approximately 9 months from the initial state. In case Z, the total fragrance intensity falls below 2.5 after approximately 4 months from the initial state.

[0119] like Figure 8 As shown in the graph, deodorizer 10 provides a longer-lasting deodorizing effect compared to deodorizer 50.

[0120] According to Embodiment 1 described above, the deodorizing device 1 includes a container 11, a deodorizing agent 12, a first cover 14, and a drive motor 20. The container 11 has a pair of container openings 11a. The container 11 has three or more chambers 11c. The deodorizing agent 12 is housed in two or more of the chambers 11c. The deodorizing agent 12 imparts a deodorizing effect to the gas it comes into contact with. The first cover 14 has a first cover opening 14a. The first cover 14 isolates a portion of the chambers 11c from the outside air. The drive motor 20 moves the first cover 14, changing the chamber in use to another chamber. Therefore, the deodorizing device 1 can keep the deodorizing agent 12 in a non-use state. The deodorizing device 1 can switch the deodorizing agent 12 used. As a result, the deodorizing device 1 can suppress large changes in the ratio of various deodorizing components for a long time. The deodorizing device 1 can maintain the deodorizing effect for a long time.

[0121] Furthermore, the deodorizing device 1 includes a cylindrical container 11. Multiple chambers 11c each have a fan-shaped shape. The first cap opening 14a also has a fan-shaped shape. Therefore, by rotating the first cap 14, the multiple chambers 11c can be blocked. As a result, the deodorizing device 1 can easily change the relative position of the container 11 and the first cap 14. The deodorizer 10 can be miniaturized.

[0122] Furthermore, the container 11 can also have a cuboid shape. Multiple chambers 11c are arranged in parallel. Therefore, the container 11 can also be installed in confined spaces.

[0123] Furthermore, the deodorizing device 1 includes a second cover 15 and a cover shaft 16. The second cover 15 has a second cover opening 15a. The second cover 15 isolates a portion of the plurality of chambers 11c from the outside air. The chambers of the second cover 15 that open to the outside air are the same as those of the first cover 14. The cover shaft 16 rotates synchronously with the first cover 14 and the second cover 15. Therefore, the deodorizer 10 can block both ends of each of the plurality of chambers 11c. The deodorizer 10 allows gas to pass through both ends of each of the plurality of chambers 11c. As a result, the deodorizing effect can be sustained for a long time.

[0124] Additionally, the deodorizing device 1 includes a storage box 2. The storage box 2 is located on the upper surface of the elevator car 101. The storage box 2 has a pair of lids 2a on its side that can be opened and closed freely. The storage box 2 houses the container 11, the deodorizing agent 12, the first lid 14, the second lid 15, and the lid shaft 16. Therefore, the deodorizing device 1 can suppress the airflow passing around the container 11. As a result, the deodorizing device 1 can reliably deliver deodorizing gas into the interior of the elevator car 101.

[0125] Additionally, the storage box 2 receives control information from the elevator. When the car 101 moves upward or downward, the storage box 2 uses this control information to open a pair of lids 2a. Therefore, the storage box 2 only allows airflow through its interior during ascent and descent. As a result, the deodorization device 1 can maintain its deodorization effect for an extended period.

[0126] Alternatively, the pair of lids 2a may not need to be opened or closed. For example, the pair of lids 2a may always be in the open state.

[0127] Furthermore, the number of chambers 11c does not have to be 16. When there are 3 or more chambers 11c, the deodorizing device 1 can maintain its effective time.

[0128] Furthermore, the deodorizing ingredients in deodorant 12 may not provide a fragrance effect. For example, deodorant 12 is a deodorant in which volatile deodorizing ingredients are impregnated in porous resin beads. For example, deodorant 12 has ingredients that remove malodors from the gas it comes into contact with.

[0129] Alternatively, the first cover opening 14a may not be a shape formed by connecting three of the plurality of chamber portions 11c. For example, the first cover opening 14a may be a shape formed by connecting two or more of the plurality of chamber portions 11c.

[0130] Alternatively, the second cover opening 15a may not be a shape formed by connecting three of the plurality of chamber portions 11c. For example, the second cover opening 15a may be a shape formed by connecting two or more of the plurality of chamber portions 11c.

[0131] Alternatively, the deodorizer 10 may not have a second cover 15. For example, if the amount of deodorizing component released by the deodorant 12 is minimal, the deodorizer 10 may not have a second cover 15. Specifically, if the vapor pressure of the fragrance in the deodorant 12 is low, and if air has difficulty passing through the deodorant 12 due to its small particle size, the amount of deodorizing component released by the deodorant 12 will be minimal.

[0132] Additionally, the drive unit 20 can also move the container 11. For example, the drive unit 20 moves the container 11 relative to the first cover 14. For example, by moving the container 11, the drive unit 20 can change the chamber in use to another chamber.

[0133] Furthermore, the unit of time for the specified period does not have to be one month. For example, the specified period could be one week. Or, the specified period could be three months.

[0134] Next, use Figure 9 A first modified example of the deodorizer 10 will be described.

[0135] Figure 9This is a diagram showing a first modified example of the deodorizer of the deodorizing device according to Embodiment 1. Figure 9 (A) is a top view of the deodorizer 10 in the first modified example. Figure 9 (B) is Figure 9 (A) B-B' sectional view.

[0136] like Figure 9 As shown, in the first modified example, the first cover 14 and Figure 9 The second cover 15 (not shown) moves continuously. For example, the first cover 14 forms an opening α between the chambers z belonging to the plurality of chamber portions 11c. The opening α is the area where one end of the chamber z overlaps with the opening 14a of the first cover during the movement of the first cover 14. The area of ​​the opening α is smaller than the area of ​​one end of the chamber z.

[0137] Compared to the first cover 14 and the second cover 15 in the first modified example, the first cover 14 and the second cover 15 in Embodiment 1 move intermittently and rapidly. In the deodorizer 10, which is not a modified example, the opening α exists for a short time. The opening α in the first comparative example exists for a longer time than the opening α in Embodiment 1.

[0138] In the first variation, as the new chamber z begins to open, the area of ​​the opening α gradually increases from 0.

[0139] When the area of ​​opening α is small, the amount of gas flowing inside chamber z is small. As the area of ​​opening α increases, the amount of gas flowing inside chamber z increases. Therefore, in the gas passing through deodorizer 10, the fragrance intensity continuously increases as the area of ​​opening α increases.

[0140] When the area of ​​opening α is greater than a certain value, the amount of gas flowing inside chamber z remains constant. This is because, when the area of ​​opening α exceeds a certain value, the conductance of opening α is greater than the conductance inside chamber z. Conductance refers to the ease with which gas can pass through at a given location.

[0141] For example, if the area of ​​the opening α is greater than half the area of ​​one end of the chamber z, the amount of gas flowing inside the chamber z is a constant saturation level.

[0142] In the first variation of Embodiment 1 described above, the first cover 14 and the second cover 15 move continuously. The area of ​​the opening α changes gradually over time. Therefore, the deodorizer 10 can make the concentration change of the deodorizing component in the passing gas gradual. As a result, the deodorizer 10 can suppress abrupt changes in the fragrance in the passing gas.

[0143] Furthermore, when the first cover 14 and the second cover 15 move intermittently, the concentration of the deodorizing component emitted by the deodorizer 10 is discontinuous. In this case, the aroma of the gas passing through the deodorizer 10 changes drastically. In the first modified example, the deodorizer 10 is able to suppress this drastic change in aroma.

[0144] Next, use Figure 10 and Figure 11 A second modification of the deodorizer 10 will be described.

[0145] Figure 10 This is a diagram showing a second variation of the deodorizer of the deodorizing device according to Embodiment 1. Figure 11 This is a graph showing the change in the total concentration of the aromatic components in the deodorizing device of the second variant of the deodorizing device in Embodiment 1.

[0146] like Figure 10 As shown, in the second modification, one of the multiple chambers that are initially open does not contain deodorant 12. For example, in the second modification, a chamber that becomes blocked after one month from the initial state does not contain deodorant 12. For example, in the second modification, chamber a does not contain deodorant 12.

[0147] exist Figure 11 The diagram shows a graph representing the relationship between the total aroma intensity of the gas after passing through the deodorizing device 1 of the second modified example and the elapsed time. The vertical and horizontal axes of the graph are different from those of the non-modified example. Figure 8 The vertical and horizontal axes of the graph shown are the same. The optimal concentration value inside the car is the same as that in non-modified examples. Figure 8 The curves shown represent the same optimal concentration values ​​inside the car.

[0148] exist Figure 11 In the graph, the relationship shown by the deodorizer 10 of the second modification is depicted with a solid line. The sawtooth shape of the graph of deodorizer 10 indicates the switching of chambers during use. The total fragrance intensity represents the optimal concentration value in the car during a period of more than 2 months but less than 14 months from the initial state.

[0149] In the second variation, the total aroma intensity in the initial state is 7.

[0150] In the second variation of Embodiment 1 described above, one of the multiple chambers that are initially open does not contain the deodorizer 12. Therefore, the total fragrance intensity in the gas passing through the deodorizer 10 can be close to a value in both the initial and subsequent states. In the initial state, the total fragrance intensity can be suppressed.

[0151] Furthermore, in the deodorizer 10 (not a variation), the concentration of the deodorizing component in the gas passing through in the initial state is higher than that in the second variation. In Embodiment 1, the strong fragrance emitted by the deodorizer 10 in the initial state may cause discomfort to the user. In the second variation, the deodorizer 10 is able to suppress the intensity of the fragrance in the initial state.

[0152] Next, use Figure 12 A third variation of the deodorizer 10 will be described.

[0153] Figure 12 This is a diagram showing a third variation of the deodorizer of the deodorizing device according to Embodiment 1.

[0154] like Figure 12 As shown, in the third modification, the last chamber to open among the plurality of chamber sections 11c is equipped with a deodorant 12'. The deodorant 12' contains different deodorizing components than the deodorant 12. The deodorant 12' also has a different fragrance than the deodorant 12. For example, in the third modification, chamber p is equipped with the deodorant 12'.

[0155] In the second variation of Embodiment 1 described above, the last chamber to open among the plurality of chamber sections 11c is equipped with a deodorant 12' containing a deodorizing ingredient different from that of the deodorant 12. Therefore, the deodorizer 10 can use different fragrances to notify... Figure 12 The first cover 14 and not shown in the figure Figure 12 The second cover 15, not shown in the diagram, has rotated one full turn. For example, maintenance personnel can then determine when it's time to replace the deodorizer.

[0156] Next, use Figure 13 A fourth modification of the deodorizer 10 will be described.

[0157] Figure 13 This is a diagram showing a fourth variation of the deodorizer of the deodorizing device according to Embodiment 1. Figure 13 (A) is a top view of the deodorizer 10 in the fourth variation. Figure 13 (B) is Figure 13 (A) C-C' section view.

[0158] like Figure 13 As shown, in the fourth modification, the deodorizer 10 does not have multiple partition surfaces 11b. In the fourth modification, the deodorizer 10 does not have multiple chamber portions 11c. In the fourth modification, the height length of the deodorizer 10 is sufficiently small relative to the diameter of the pair of container openings 11a. For example, in the fourth modification, the height length of the deodorizer 10 is one-tenth the diameter of the pair of container openings 11a.

[0159] Gas passing through the first cap opening 14a passes inside the container 11 through the area sandwiched between the first cap opening 14a and the second cap opening 15a, and in the vicinity of that area. The deodorant 12, which is not present in this area, does not come into contact with the gas outside the container. Therefore, the deodorizing effect of the deodorant 12, which is not present in this area, is not diminished.

[0160] With the first cover 14 and the second cover 15 rotated, the gas passing through the deodorizer 10 passes through the deodorant 12 which contains deodorizing ingredients.

[0161] In a fourth variation, for example, the first cover 14 and the second cover 15 move intermittently. In a fourth variation, for example, the first cover 14 and the second cover 15 may also move continuously.

[0162] In the fourth variation of Embodiment 1 described above, the deodorizer 10 does not have multiple partition surfaces 11b. In the fourth variation, the height length of the deodorizer 10 is sufficiently small relative to the diameter of the pair of container openings 11a. Therefore, gas passing through the first cap opening 14a passes through the area sandwiched between the first cap opening 14a and the second cap opening 15a inside the container 11, as well as the vicinity of that area. The deodorizer 10 can prevent a reduction in the deodorizing effect of the deodorant 12, which is not present in that area. In the fourth variation, the deodorizer 10 can achieve an effect similar to that of the deodorizer 10 in the non-variant embodiment without having multiple chambers 11c.

[0163] Implementation Method 2

[0164] Figure 14 This is a diagram showing the deodorizer of the deodorizing device in Embodiment 2. Figure 14 (A) is a three-dimensional view of the deodorizer. Figure 14 (B) is a top view of the deodorizer. Figure 14 (C) is a diagram showing the situation where a pair of sheets are peeled off. Figure 14 (D) is Figure 14 (B) is a cross-sectional view along line D-D'. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0165] In Implementation 2, the number of chambers in use increases over time.

[0166] like Figure 14 As shown, the deodorizing device 1 has a deodorizer 30 inside the storage box 2.

[0167] The deodorizer 30 includes a container 31, a deodorizing agent 12, a screen 33, a pair of plates 34, and a peeler 35.

[0168] For example, container 31 has a cuboid shape. Container 31 has an interior cavity. For example, container 31 has a pair of container openings 31a, a plurality of partition surfaces 31b, and a plurality of chambers 31c.

[0169] A pair of container openings 11a are respectively provided on a pair of opposite sides of the container 31. For example, the pair of container openings 31a are respectively equivalent to the entirety of a pair of side surfaces in the container 31.

[0170] Multiple partition surfaces 31b are respectively disposed inside the container 31. The partition surfaces 31b are respectively disposed from one of a pair of container openings 31a to the other. For example, the partition surfaces 31b are respectively disposed perpendicular to the pair of container openings 31a. For example, the pair of container openings 31a are respectively disposed parallel to each other. The partition surfaces 31b divide the interior of the container 31. For example, there are 5 partition surfaces 31b. For example, the partition surfaces 31b divide the interior of the container 31 into 6 equal parts.

[0171] The multiple chambers 31c are regions within the container 31 divided by multiple partition surfaces 31b. Each chamber 31c has a columnar shape with a pair of container openings 31a as its base. For example, each chamber 31c has a rectangular cross-section. For example, six chambers 31c are provided in the container 31. For example, the multiple chambers 31c are arranged in parallel.

[0172] For example, deodorant 12 is the same deodorant as in embodiment 1.

[0173] For example, multiple screens 33 have a mesh structure. Multiple screens 33 are respectively disposed at both ends of multiple chamber portions 31c. Multiple screens 33 allow gas to pass through. Multiple screens 33 respectively prevent the deodorant 12 from leaking out of the multiple chamber portions 31c.

[0174] For example, a pair of plates 34 each have a rectangular shape. A pair of plates 34 each have an adhesive 34a. A pair of plates 34 are detachably bonded to a pair of container openings 31a by the adhesive 34a. A pair of plates 34 isolates the multiple chambers 31c blocked by the pair of plates 34 from the gas outside the container 31.

[0175] For example, a peeler 35 is disposed on the side of the container 31. For example, the peeler 35 is connected to one end of each of a pair of sheets 34. For example, the peeler 35 pulls on one end of each of the pair of sheets 34. The peeler 35 peels the pair of sheets 34 off the container 31 respectively. The peeler 35 controls the peeling position of each of the pair of sheets 34.

[0176] The deodorizer 30 increases the number of chambers in use by peeling off a pair of plates 34 separately. The deodorizer 30 increases the number of chambers in use at regular intervals.

[0177] According to Embodiment 2 described above, the container 31 has a cuboid shape. Multiple chambers 31c are arranged in parallel. Therefore, the container 31 can also be installed in narrow spaces.

[0178] Furthermore, the deodorizing device 1 includes a pair of plates 34. The pair of plates 34 are detachably and adhesively attached to a pair of container openings 31a. Therefore, the deodorizer 30 can use a new deodorant 12 at regular intervals. As a result, the deodorizing device 1 can maintain its deodorizing effect for a long time.

[0179] Furthermore, regarding the changes in the intensity and properties of the fragrance produced by the deodorizer 30, as shown in Embodiment 1, the effect of highly volatile deodorizing components is greater than that of less volatile components. Therefore, when using the new deodorizer 12, the deodorizer 30 can maintain a constant deodorizing effect without sealing the chamber used for extended periods.

[0180] Furthermore, the shape of container 31 is not limited to rectangle. For example, container 31 may have the same shape as container 11 in embodiment 1. In this case, the pair of plates 34 are circular. For example, the pair of plates 34 may have radial cuts. The pair of plates 34 may peel off a region of one of the plurality of chamber portions 11c along the cuts at regular intervals.

[0181] Alternatively, the deodorizer 30 may not need a peeler 35, provided it can peel off the pair of plates 34 at regular intervals. For example, the deodorizer 30 may not have a peeler 35. For example, maintenance personnel may peel off the pair of plates 34 at regular intervals.

[0182] Furthermore, as long as the number of chambers in use increases over time, the deodorizer 30 may not need to have a pair of plates 34. For example, the deodorizer 30 may have a non-modified version. Figure 14 Container 11 (not shown) is used instead of container 31. For example, Figure 14 The first cover 14 and not shown in the figure Figure 14 The second cover 15, not shown in the diagram, has a fan-shaped structure. For example, the first cover 14 will... Figure 14 The opening 14a of the first cover (not shown) widens. For example, the second cover 15 will... Figure 14 The second cover opening 15a (not shown in the figure) is enlarged.

[0183] Implementation Method 3

[0184] Figure 15This is a diagram showing the deodorization device in Embodiment 3. Figure 16 This diagram shows the drive unit of the deodorizing device in Embodiment 3. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 or Embodiment 2 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0185] like Figure 15 As shown, in embodiment 3, the deodorization device 1 includes a drive motor 40.

[0186] The drive unit 40 is equipped with a propeller 41.

[0187] The propeller 41 is equipped with a propeller fan 41a. For example, the propeller 41 is rotatably positioned above the storage box 2. For example, the propeller 41 is positioned above one of the pair of box covers 2a.

[0188] A portion of the propeller fan 41a is located directly above the space between the hoistway 100 and the car 101. For example, the width of this space is 1 meter.

[0189] The propeller 41 rotates using the airflow generated near the car 101 as the car 101 ascends or descends. This airflow is observed from the car 101 as it moves relative to the hoistway 100. When the car 101 ascends, this airflow is a descending airflow relative to the car 101. When the car 101 descends, this airflow is an ascending airflow relative to the car 101.

[0190] The propeller 41 rotates due to the airflow within the propeller fan 41a. For example, when the car 101 is ascending, the propeller 41 rotates in the forward direction. For example, when the car 101 is descending, the propeller 41 rotates in the reverse direction.

[0191] like Figure 16 As shown, the drive mechanism 40 includes a propeller 41, a first gear 42, a second gear 43, an escape wheel 44, an escape fork 45, pawls 46, and a pair of stops 47. For example, the drive mechanism 40 is connected to the storage box 2. The drive mechanism 40 rotates the cover shaft 16.

[0192] For example, the first gear 42 is a helical gear. The first gear 42 is connected to the shaft of the propeller 41. The first gear 42 rotates synchronously with the rotation of the propeller 41.

[0193] For example, the second gear 43 is a helical gear. The teeth of the second gear 43 correspond to the teeth of the first gear 42. The second gear 43 is rotatably configured to mesh with the first gear 42. For example, the second gear 43 and the first gear 42 together form a helical gear. For example, the axis of rotation of the second gear 43 is parallel to the cover shaft 16.

[0194] The escape wheel 44 has a disc shape. The escape wheel 44 has multiple protrusions 44a on its outer circumferential surface. The escape wheel 44 is connected to the cover shaft 16. The central axis of the escape wheel 44 is coaxial with the cover shaft 16. For example, the escape wheel 44 rotates synchronously with the cover shaft 16.

[0195] One end of the escape fork 45 has a double-fork shape. The escape fork 45 has a pair of feed pads 45a at one end. The escape fork 45 is rotatably connected to a shaft 45b at the base of the double forks. The other end of the escape fork 45 is connected to the rotating shaft of the second gear 43. The escape fork 45 is positioned such that the escape wheel 44 is located between the double forks. The escape fork 45 is positioned so that the pair of feed pads 45a can contact a plurality of protrusions 44a.

[0196] The escape fork 45 is configured to rotate freely about axis 45b. The escape fork 45 receives rotational drive from the second gear 43. For example, when the second gear 43 rotates in the forward direction, one end of the escape fork 45 moves in one direction. When one end of the escape fork 45 moves in one direction, the other end of the escape fork 45 moves in the opposite direction. For example, when the second gear 43 rotates in the reverse direction, one end of the escape fork 45 moves in the opposite direction. When one end of the escape fork 45 moves in the opposite direction, the other end of the escape fork 45 moves in one direction.

[0197] A pair of inserts 45a applies an external force to the plurality of protrusions 44a only from one direction. If the pair of inserts 45a comes into contact with one of the protrusions 44a from another direction, the pair of inserts 45a does not cause the position of that protrusion 44a to move. The pair of inserts 45a moves in the other direction without moving the position of the protrusion 44a.

[0198] For example, the pawl 46 has a rod-like shape. One end of the pawl 46 is connected to the center of the second gear 43. The pawl 46 moves in a pendulum-like motion around one end. The pawl 46 moves synchronously with the rotation of the second gear 43.

[0199] One of the pair of stops 47 is disposed on one side of the claw 46. The other of the pair of stops 47 is disposed on the other side of the claw 46. Each of the pair of stops 47 is configured to interfere with the movement of the claw 46. Each of the pair of stops 47 defines the range of motion that the claw 46 can move. For example, if the claw 46 moves to one side, one of the stops 47 stops the movement of the claw 46 by collision.

[0200] The drive unit 40 uses the airflow generated by the lifting motion of the car 101 to rotate the cover shaft 16. The drive unit 40 moves the first cover 14 and the second cover 15 via the cover shaft 16. The drive unit 40 changes the relative position of the first cover 14 and the second cover 15 with respect to the container 11.

[0201] For example, when the car 101 is rising, the drive motor 40 rotates the cover shaft 16 clockwise. For example, when the car 101 is falling, the drive motor 40 does not rotate the cover shaft 16.

[0202] For example, when the car 101 is ascending, the propeller 41 is subjected to a downdraft. Under the influence of the downdraft, the propeller 41 rotates in the forward direction. The first gear 42 rotates in the forward direction synchronously with the propeller 41. The second gear 43 rotates in the forward direction synchronously with the first gear 42. The escape fork 45 is subjected to a rotational driving force by the second gear 43. One end of the escape fork 45 moves in one direction. A pair of bearings 45a apply an external force to one of the plurality of protrusions 44a from one direction. The escape wheel 44 rotates in the forward direction. The cover shaft 16 rotates clockwise synchronously with the rotation of the escape wheel 44.

[0203] For example, when the car 101 is descending, the cover shaft 16 does not rotate. When the car 101 is descending, one end of the escape fork 45 moves in the opposite direction. A pair of pallet plates 45a contact one of the plurality of protrusions 44a from multiple directions. The pair of pallet plates 45a moves in the opposite direction without moving the position of the protrusions 44a.

[0204] According to Embodiment 3 described above, the drive unit 40 includes a propeller 41. The propeller 41 is disposed above the elevator car 101. The propeller 41 is rotatably disposed on the drive unit 40. The propeller 41 rotates due to the airflow generated around the car 101 when the car 101 moves up or down. The drive unit 40 uses the rotational driving force to change the relative position of the container 11 and the first cover 14. Therefore, the deodorizing device 1 can rotate the first cover 14 and the second cover 15 of the deodorizer 10 without the need for electrical equipment.

[0205] In addition, a pair of infeed tiles 45a can also be configured to apply external force to the multiple protrusions 44a only from the other direction.
