Detailed Description

The manner in which the invention can be practiced is now described with reference to the accompanying drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals. Repeated description of this portion is appropriately simplified or omitted.

Embodiment 1.

Fig. 1 is a diagram showing a deodorizing device according to embodiment 1.

As shown in fig. 1, for example, a deodorizing device 1 is used for an elevator.

The hoistway 100 penetrates floors of a building, not shown. The car 101 of the elevator is disposed inside the hoistway 100. The car 101 rises and falls inside the hoistway 100. The car 101 is controlled to move up and down by a control panel, not shown.

The deodorizing device 1 includes a storage box 2, a fan 3, and a deodorizer 10. For example, the deodorizing device 1 is provided at the upper part of the car 101.

For example, the storage box 2 is a rectangular parallelepiped box. The storage box 2 includes a pair of box covers 2a on a pair of opposite side surfaces. The storage box 2 includes a controller 2b. The storage box 2 is provided on the upper surface of the car 101. The storage box 2 is provided such that one of the pair of box covers 2a faces the side wall of the hoistway 100. For example, the storage box 2 is provided such that one of the pair of box covers 2a protrudes from the car 101 when viewed in the vertical direction. For example, the storage box 2 is electrically connected to a control panel. The storage box 2 acquires control information of the car 101 from the control panel.

For example, the pair of covers 2a are provided to be openable and closable by hinges. For example, the pair of cover 2a opens and closes a partial region of each of the pair of side surfaces of the storage box 2.

The controller 2b is electrically connected to the control panel. The controller 2b acquires control information from the control panel. For example, the controller 2b controls the opening and closing operations of the respective pair of cover 2 a.

For example, the controller 2b controls the opening and closing operations of the respective pair of cover 2a using control information. When the car 101 moves up or down, the pair of covers 2a opens under the control of the controller 2 b. When the car 101 is stopped, the pair of covers 2a perform a closing operation under the control of the controller 2 b. When the car 101 is in a stopped state, the pair of covers 2a are in a closed state.

The fan 3 includes blades 3a, a suction port 3b, and a discharge port 3c. The fan 3 is provided on the upper surface of the car 101. The fan 3 is provided laterally to the storage box 2. The fan 3 generates an airflow from the suction port 3b toward the discharge port 3c by rotating the vane 3 a. The fan 3 sucks air from the suction port 3 b. The fan 3 blows air from the air outlet 3c.

The suction port 3b is connected to the other of the pair of cover 2 a.

The air outlet 3c is connected to the upper surface of the car 101. The air outlet 3c is connected to the inside of the car 101.

The deodorizer 10 is provided inside the storage box 2. The deodorizer 10 gives a deodorizing component to the gas passing through the inside.

The deodorizing device 1 blows the gas to which the deodorizing component is added into the inside of the car 101 during the lifting operation of the car 101.

For example, when the car 101 is lifted, the controller 2b opens the pair of covers 2 a. When the pair of covers 2a is opened, the fan 3 sucks in the air in the storage box 2 through the suction port 3 b. The fan 3 generates a flow of air from one of the pair of case covers 2a toward the other inside the storage case 2. The gas passes through the inside of the deodorizer 10. The deodorizer 10 imparts a deodorizing component to the gas. The fan 3 blows the air from the air outlet 3c into the car 101.

For example, when the car 101 stops, the controller 2b brings the pair of covers 2a into the closed state. For example, when the car 101 is stopped, the deodorizing device 1 stops blowing the gas to which the deodorizing component is added into the car 101.

Next, the mechanism of the deodorizer 10 will be described with reference to fig. 2.

Fig. 2 is a diagram showing a deodorizer of the deodorizing device of embodiment 1. Fig. 2 (a) is a perspective view of an example of the deodorizer 10. Fig. 2 (B) is a sectional view of the deodorizer 10. Fig. 2 (C) is a Y-view in fig. 2 (B).

The deodorizer 10 includes a container 11, a deodorizer 12, a screen 13, a first cover 14, a second cover 15, a cover shaft 16 and a drive machine 20.

For example, the container 11 has a cylindrical shape. The container 11 has a hollow inside. For example, the container 11 includes a pair of container openings 11a, a plurality of partition surfaces 11b, and a plurality of chamber portions 11c.

The pair of container openings 11a are provided on a pair of opposite side surfaces of the container 11. For example, the pair of container openings 11a are provided on a pair of bottom surfaces of the container 11. For example, the pair of container openings 11a corresponds to the entirety of the respective bottom surfaces of the container 11.

The plurality of partition surfaces 11b are provided in the container 11. The plurality of partition surfaces 11b are provided from one to the other of the pair of container openings 11 a. For example, the plurality of partition surfaces 11b are provided perpendicularly to the pair of container openings 11 a. For example, the plurality of partition surfaces 11b are each provided radially from the center axis of the cylinder of the container 11. The plurality of partition surfaces 11b divide the interior of the container 11. For example, 16 partition surfaces 11b are provided. For example, the plurality of dividing surfaces 11b divide the interior 16 of the container 11 equally.

The plurality of chamber portions 11c are regions of the interior of the container 11 partitioned by the plurality of partition surfaces 11 b. Each of the plurality of chamber portions 11c has a columnar shape with the pair of container openings 11a as a bottom surface. For example, each of the plurality of chamber portions 11c has a fan-shaped cross section. For example, 16 chamber portions 11c are provided in the container 11.

For example, the deodorant 12 is a deodorant in which a perfume is impregnated into porous resin beads. For example, essential oils, substances obtained by diluting essential oils with solvents, and the like can be used as the perfume. For example, the fragrance is a volatile deodorant ingredient. For example, the deodorant 12 has a plurality of volatile deodorant components. The multiple volatile deodorizing components respectively use fragrance, and have masking deodorizing effect on malodor.

The deodorant 12 is provided in each of the plurality of chamber portions 11 c. The inside of the deodorant 12 allows the gas to freely pass through. For example, the deodorant 12 passes the gas through the inside, thereby imparting a deodorant component to the passed gas.

For example, the plurality of screens 13 have a mesh structure. The plurality of screens 13 are provided at both ends of each of the plurality of chamber portions 11 c. A plurality of screens 13 pass the gas. The plurality of screens 13 block the deodorant 12 from leaking out of the plurality of chamber portions 11c, respectively.

For example, the first cover 14 is formed in a disk shape. The first cover 14 includes a first cover opening 14a. The first cover 14 is provided so as to face one of the pair of container opening portions 11 a. For example, the center of the disk of the first cover 14 is located on the extension of the cylindrical axis of the container 11. For example, the side surface of the first cover 14 faces one of the pair of container openings 11 a.

For example, the first cover 14 is provided on the upstream side of the container 11 in the air flow flowing through the not-shown case cover 2 a. The first cover 14 is provided so as to close one end of the chamber portion of the plurality of chamber portions 11c that is not opposed to the first cover opening 14a. The first cover 14 is provided so as not to block one end of the chamber portion of the plurality of chamber portions 11c that faces the first cover opening portion 14a. The first cover 14 isolates the plurality of chamber portions 11c blocked by the first cover 14 from the gas outside the container 11.

For example, the first cover opening 14a is formed by cutting out a part of the first cover 14. The first lid opening portion 14a has a shape in which cross sections of a plurality of the chamber portions 11c are connected. For example, the first lid opening 14a has a fan shape. For example, the first lid opening portion 14a is a fan shape formed by connecting the cross sections of 3 of the plurality of chamber portions 11 c. The first cover opening 14a has an area equal to the sum of the cross-sectional areas of 2 or more and less than the entire number of the plurality of chamber portions 11 c. For example, the first cover opening portion 14a has an area equal to an area that sums up the cross sections of 3 of the plurality of chamber portions 11 c.

For example, the second cover 15 is formed in a disk shape. The second cover 15 includes a second cover opening 15a. The second cover 15 is provided so as to face the other of the pair of container opening portions 11 a. For example, the center of the disk of the second cover 15 is located on the extension of the cylindrical axis of the container 11. For example, the side surface of the second cover 15 faces the other of the pair of container openings 11 a.

For example, the first cover 14 is provided on the leeward side of the container 11 in the air flow flowing through the case cover 2 a. The second cover 15 is provided so as to close the other end of the chamber portion of the plurality of chamber portions 11c, which does not face the second cover opening 15a. The second cover 15 is provided so as not to block the other end of the chamber portion of the plurality of chamber portions 11c facing the second cover opening portion 15a. The second cover 15 isolates the plurality of chamber portions 11c blocked by the second cover 15 from the gas outside the container 11.

The second cover 15 is provided so that the plurality of chamber portions 11c facing the second cover opening 15a and the plurality of chamber portions 11c facing the first cover opening 14a coincide with each other.

For example, the second cover opening 15a is formed by cutting out a part of the second cover 15. The second cover opening 15a has a shape in which cross sections of a plurality of the chamber portions 11c are connected. For example, the second cover opening 15a has a shape of a part of a fan shape. For example, the second cover opening 15a is a fan shape formed by connecting the cross sections of 3 of the plurality of chamber portions 11 c. The second cover opening 15a has an area equal to the sum of the cross-sectional areas of 2 or more and less than the entire number of the plurality of chamber portions 11 c. For example, the second cover opening portion 15a has an area equal to an area that sums up the cross sections of 3 of the plurality of chamber portions 11 c.

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 synchronization with the rotation of the first cover 14. The cover shaft 16 is connected to the center of the second cover 15 in synchronization with the rotation of the second cover 15. The cover shaft 16 rotates in synchronization 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.

For example, the driving machine 20 includes a motor 21, a belt 22, and a cover controller 23. For example, the drive machine 20 is connected to the cover shaft 16. For example, the drive machine 20 rotates the cover shaft 16. The driver 20 moves the first cover 14 and the second cover 15 through the cover shaft 16. The driver 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 and the container 11 change, the position of the chamber portion 11c blocked by the first cover 14 and the second cover 15 among the plurality of chamber portions 11c changes.

For example, the motor 21 includes a rotation shaft. The motor 21 generates a rotational driving force to the rotation shaft.

For example, the belt 22 is an endless belt. One end of the belt 22 is wound around the cover shaft 16 so as to be movable in accordance with the rotation of the cover shaft 16. The other end of the belt 22 is wound around the rotation shaft of the motor 21 so as to be movable along the rotation shaft of the motor 21. For example, the belt 22 transmits the rotational driving force of the motor 21 to the cover shaft 16.

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 an arbitrary rotational speed. For example, the cover controller 23 rotates the first cover 14 and the second cover 15 by an arbitrary angle by the motor 21.

In the storage box 2 not shown in fig. 2, the gas passes through the inside of the plurality of chamber portions 11c which are not blocked by the first cover 14 or the second cover 15. The deodorizer 10 gives a deodorizing component to the gas in the inside of the plural chamber portions 11c. Hereinafter, the chamber portion 11c in a state where the gas passes through the inside among the plurality of chamber portions 11c is referred to as a "chamber in use (cell)".

Next, an example of a process of changing the chamber in use of the deodorizer 10 will be described with reference to fig. 3 and 4.

Fig. 3 is an X-direction view of a deodorizer of the deodorizing device of embodiment 1. Fig. 4 is a view showing an X-direction view of the deodorizer of the deodorizing device according to embodiment 1 in a time-series manner.

As shown in fig. 3, for example, the deodorizer 10 includes 16 chamber portions 11c. For example, in the deodorizer 10, 3 of the plurality of chamber portions 11c are chambers in use. The first cover opening 14a is located in a clockwise direction from the twelve-point direction of the timepiece. The deodorizer 10 in fig. 3 is in a state where the gas does not pass. The state of the deodorizer 10 in fig. 3 is defined as an initial state.

For example, the plurality of chamber portions 11c are marked with reference numerals a to p with reference to the twelve-point direction. For example, a chamber portion existing at the twelve points of the timepiece among the plurality of chamber portions 11c is a chamber a. The chamber portion adjacent to the right side of the chamber a among the plurality of chamber portions 11c is a chamber b. Likewise, chambers c to p are sequentially arranged in the clockwise direction.

For example, the first cover 14 and the second cover 15, not shown in fig. 3, are rotated clockwise by an angle corresponding to 1 of the plurality of chamber portions 11c every predetermined time. For example, the first cover 14 and the second cover 15 are rotated clockwise by 22.5 degrees every 1 month.

The deodorant 12 has a reduced effect of imparting a deodorizing component over time. For example, the deodorant 12 is distinguished according to the time used. For example, in the case where the time of use is less than 1 month, the deodorant 12 is in a "new" state. For example, when the time period of use is 1 month or more and less than 2 months, the deodorant 12 is in the "old 1" state. For example, when the time of use is 2 months or longer, the deodorant 12 is in the "old 2" state. For example, in the initial state, the deodorant 12 of the chambers a, b, and c is in a "new" state. Hereinafter, the deodorants 12 of the chambers a to p are defined as deodorants 12a to 12p, respectively.

As shown in fig. 4, for example, the deodorizer 10 changes the position of the chamber in use every 1 month. Fig. 4 (a) shows the deodorizer 10 in an initial state. Fig. 4 (B) shows the deodorizer 10 after 1 month from the initial state. Fig. 4 (C) shows the deodorizer 10 after 2 months from the initial state. Fig. 4 (D) shows the deodorizer 10 after 3 months from the initial state.

In fig. 4 (a), the deodorant 12a, the deodorant 12b, and the deodorant 12c are in a "new" state.

In fig. 4 (B), the first cover 14 and the second cover 15, which is not shown in fig. 4, are rotated clockwise by 22.5 degrees compared with the initial state. Chamber a is not the chamber in use. Chamber d is the chamber in use. The deodorant 12b and the deodorant 12c are in the state of "old 1". The deodorant 12d is in a "new" state. The deodorizer 10 emits a gas in which deodorizing components in the state of "old 1" and "new" are mixed.

In fig. 4 (C), the first cover 14 and the second cover 15 are rotated clockwise by 22.5 degrees compared to the state shown in fig. 4 (B). Chamber b is not the chamber in use. Chamber e is the chamber in use. The deodorant 12c is in the state of "old 2". The deodorant 12d is in the state of "old 1". The deodorant 12e is in a "new" state. The deodorizer 10 emits a gas in which deodorizing components in the state of "old 2", "old 1" and "new" are mixed.

In fig. 4 (D), the first cover 14 and the second cover 15 are rotated clockwise by 22.5 degrees compared to the state shown in fig. 4 (C). Chamber c is not the chamber in use. Chamber f is the chamber in use. The deodorant 12d is in the state of "old 2". The deodorant 12e is in the state of "old 1". The deodorant 12f is in a "new" state. The deodorizer 10 emits a gas in which deodorizing components in the state of "old 2", "old 1" and "new" are mixed.

Thereafter, the deodorizer 10 performs the same operation as described above every 1 month. The deodorizer 10 emits a gas in which deodorizing components in the "old 2", "old 1" and "new" states are mixed, during a period of 13 months from the initial state.

In the case where 14 months have elapsed from the initial state, the chambers in use are chamber o, chamber p, and chamber a. In the chamber a, the deodorant 12a is in the state of "old 1". The deodorizer 10 emits a gas in which deodorizing components in the state of "old 2" and "old 1" are mixed.

When 15 months or more have elapsed from the initial state, the deodorizer 10 emits a gas in which the deodorizing components in the "old 2" state are mixed.

Next, a case where the deodorizing effect of the deodorizer 10 is changed will be described with reference to fig. 5 to 8, as compared with the same case of the deodorizer 50 having the conventional structure.

Fig. 5 is a diagram showing a conventional deodorizing device as a comparative example of the deodorizing device in embodiment 1. Fig. 6 is a diagram showing a case where the fragrance intensity of the deodorizing component of the deodorizing device according to embodiment 1 is changed. Fig. 7 is a diagram showing a case where the ratio of the fragrance intensity of the deodorizing component of the deodorizing device according to embodiment 1 is changed. Fig. 8 is a diagram showing a case where the total fragrance intensity of the deodorizing component of the deodorizing device according to embodiment 1 is changed.

As shown in fig. 5, for example, the deodorizer 50 of the conventional structure has a cylindrical shape. The deodorizer 50 includes the deodorant 12 therein. The deodorizer 50 does not include the plurality of chamber portions 11c, the first cover 14, and the second cover 15, as compared with the deodorizer 10 of embodiment 1, which is not shown in fig. 5. The deodorizer 50 applies a deodorizing component to the gas using the entire deodorizing agent 12 inside.

Fig. 6 is a graph showing a relationship between the flavor intensity of the deodorizing component contained in the gas after passing through the deodorizing device 1 and the elapsed time. The fragrance intensity is the intensity of fragrance of the deodorizing ingredient perceived by a person. The fragrance intensity has a positive correlation with the concentration of the deodorizing ingredient contained in the gas. The unit of fragrance intensity is arbitrary [ a.u ].

The vertical axis represents the flavor intensity of the deodorizing component contained in the gas after passing through the deodorizing device 1. The unit of the vertical axis is arbitrary unit [ a.u ].

The horizontal axis represents the time elapsed from the initial state. The units of the horizontal axis are arbitrary units [ a.u ]. For example, the unit of the horizontal axis is 1 month.

For example, the deodorant 12 includes a deodorant component a and a deodorant component B. The deodorizing component A is a component having relatively high volatility. The deodorizing component B is a component having lower volatility than the deodorizing component a. For example, when the sum of the concentration of the deodorizing component a and the concentration of the deodorizing component B in the gas in contact is greater than a certain value, the deodorizing agent 12 exerts a deodorizing effect. For example, when the ratio of the concentration of the deodorizing component a to the concentration of the deodorizing component B in the gas in contact is within a certain range, the deodorizing agent 12 exhibits a deodorizing effect.

The intensity of the fragrance imparted to the gas by the deodorant 12 decreases with time. The fragrance intensity x (t) is represented by the following formula (1).

x(t)＝A*exp(-t/ε) (1)

t is the time elapsed from the initial state. A is the initial intensity representing the fragrance intensity in the initial state. Epsilon is the attenuation coefficient inherent to each deodorizing ingredient. For example, the value of epsilon of the deodorizing component A is 2 times the value of epsilon of the deodorizing component B.

In the graph of fig. 6, the relationship shown in the deodorizer 10 of embodiment 1 is depicted by a solid line. The thin line in the solid line indicates the relationship of the deodorizing component A. The bold line in the solid line indicates the relationship of the deodorizing component B.

In the deodorizer 10, the fragrance intensity of the deodorizing ingredient a decreases from 6 in the initial state. In the case where 1 month has elapsed from the initial state, the chamber in use is switched to the other chamber. When the chamber is switched in use, the fragrance intensity of the deodorizing ingredient a increases. The saw tooth shape of the graph of the deodorant composition a indicates that the chamber is switched in use. The fragrance intensity of the deodorizing ingredient a exhibits a value within a certain range during a period of 2 months or more and less than 14 months from the initial state. The fragrance intensity of the deodorizing ingredient a decreases during 14 months or later from the initial state.

In the deodorizer 10, the fragrance intensity of the deodorizing component B decreases from 3 in the initial state. The graph of the flavor intensity of the deodorizing ingredient B shows the same tendency as the graph of the flavor intensity of the deodorizing ingredient a.

In the graph of fig. 6, the relationship shown in the deodorizer 50 of the conventional structure is depicted by a broken line or a one-dot chain line. The dotted line shows the relationship of the concentration of the deodorizing ingredient a. The one-dot chain line indicates the relationship of the concentration of the deodorizing ingredient B. In order to equalize the conditions, the air volume flowing through the deodorizer 50 of the conventional structure is set to a value 3/16 times the air volume flowing through the deodorizer 10.

In the deodorizer 50, the fragrance intensity of the deodorizing component A monotonically decreases from 6 in the initial state. Since the set air volume is different, the rate of decrease is slower than the rate of decrease in the fragrance intensity of the deodorizing component a in the deodorizer 10.

In the deodorizer 50, the fragrance intensity of the deodorizing component B monotonically decreases from 3 in the initial state. Since the set air volume is different, the rate of decrease is slower than the rate of decrease in the fragrance intensity of the deodorizing component B in the deodorizer 10.

In the deodorizer 50, the odor intensity of the deodorizing component a is weaker than the odor intensity of the deodorizing component B when about 8 months have elapsed from the initial state.

Fig. 7 is a graph showing a relationship between a ratio of deodorizing components contained in the gas after passing through the deodorizing device 1 and an elapsed time.

The vertical axis represents the ratio A/B of the flavor intensity of the gas after passing through the deodorizing device 1. The unit of the vertical axis is arbitrary unit [ a.u ]. The ratio A/B of the fragrance intensity is the ratio of the fragrance intensity of the deodorizing component A to the fragrance intensity of the deodorizing component B.

For example, when the value of the ratio a/B of the flavor intensity in the gas in contact is within a certain range, the deodorant 12 exerts a deodorizing effect. This certain range is called an optimal composition ratio. For example, the optimum composition ratio is between 1.0 and 1.6.

The horizontal axis represents the time elapsed from the initial state. The units of the horizontal axis are arbitrary units [ a.u ]. For example, the unit of the horizontal axis is 1 month.

In the graph of fig. 7, the relationship shown in the deodorizer 10 of embodiment 1 is depicted by a solid line. The saw tooth shape of the graph of the deodorizer 10 indicates that the chamber is switching in use. The ratio of the flavor intensity is expressed as a value of the optimum component ratio during a period of 2 months or more and less than 14 months from the initial state.

In the graph of fig. 7, the relationship shown in the deodorizer 50 of the conventional structure is depicted by a broken line. In order to equalize the conditions, the air volume flowing through the deodorizer 50 of the conventional structure is set to a value 3/16 times the air volume flowing through the deodorizer 10.

In the deodorizer 50, the ratio a/B of fragrance intensity monotonically decreases from the initial state 2. In the deodorizer 50, the ratio a/B of fragrance intensity is lower than 1.0 when about 8 months have elapsed from the initial state. When the ratio a/B of the fragrance intensity is less than 1, the fragrance generated from the deodorant 12 becomes a fragrance completely different from the initial state.

As shown in the graph of fig. 7, the deodorizer 10 maintains the deodorizing effect for a longer time than the deodorizer 50. The deodorizer 10 keeps the nature of the fragrance constant, and keeps the masking effect for a long time.

Fig. 8 shows a graph showing the relationship between the total fragrance intensity contained in the gas after passing through the deodorizing device 1 and the elapsed time. The total fragrance intensity refers to the sum of the fragrance intensities of the individual deodorizing ingredients.

The vertical axis represents the total fragrance intensity of the deodorizing component contained in the gas after passing through the deodorizing means 1. The unit of the vertical axis is arbitrary unit [ a.u ].

For example, when the value of the total fragrance intensity in the gas in contact is within a certain range, the deodorant 12 exerts a deodorizing effect. This certain range is called the optimal concentration in the car. For example, the optimal concentration in the car is between 2.5 and 5.0.

The horizontal axis represents the time elapsed from the initial state. The units of the horizontal axis are arbitrary units [ a.u ]. For example, the unit of the horizontal axis is 1 month.

In the graph of fig. 8, the relationship shown in the deodorizer 10 of embodiment 1 is depicted by a solid line. The saw tooth shape of the graph of the deodorizer 10 indicates that the chamber is switching in use. The total fragrance intensity is expressed as a value of the optimum concentration in the car during a period of 2 months or more and less than 14 months from the initial state.

In the graph of fig. 8, the relationship shown in the deodorizer 50 of the conventional structure is depicted by a broken line. As case X, case Y, and case Z, the air volume flowing in the deodorizer 50 of the existing structure is set to a value of 3/16 times, a value of 2/16 times, and a value of 1/16 times, respectively, of the air volume flowing in the deodorizer 10.

In the deodorizer 50, in the case of case X, the total fragrance intensity monotonically decreases from 9 in the initial state. Thereafter, the total fragrance intensity is less than 2.5 in the case of about 9 months from the initial state.

In the deodorizer 50, in the case of case Y or case Z, the total fragrance intensity is gently reduced compared with the case of case X. In the case of case Y or case Z, the total fragrance intensity in the initial state is weaker than in the case of case X. In case Y, the total fragrance intensity is below 2.5 after about 9 months from the initial state. In case Z, the total fragrance intensity is below 2.5 after about 4 months from the initial state.

As shown in the graph of fig. 8, the deodorizer 10 maintains the deodorizing effect for a longer time than the deodorizer 50.

According to embodiment 1 described above, the deodorizing device 1 includes the container 11, the deodorizing agent 12, the first cover 14, and the driving unit 20. The container 11 includes a pair of container openings 11a. The container 11 includes 3 or more chamber portions 11c. The deodorant 12 is stored in 2 or more of the plurality of chamber portions 11c. The deodorant 12 imparts a deodorizing effect to the contacted gas. The first cover 14 includes a first cover opening 14a. The first cover 14 isolates a part of the plurality of chamber portions 11c from the outside air. The drive machine 20 changes the chamber in use to another chamber by moving the first cover 14. Therefore, the deodorizing device 1 can keep the deodorizing agent 12 in a state of not being used. The deodorizing device 1 can switch the deodorizing agent 12 used. As a result, the deodorizing device 1 can suppress a large change in the ratio of the plurality of deodorizing components for a long period of time. The deodorizing device 1 can maintain the deodorizing effect for a long time.

The deodorizing device 1 includes a cylindrical container 11. Each of the plurality of chamber portions 11c has a fan shape. The first lid opening 14a has a fan shape. Therefore, by rotating the first cover 14, the plurality of chamber portions 11c can be blocked. As a result, the deodorizing device 1 can easily change the relative position of the container 11 and the first cover 14. The deodorizer 10 can be miniaturized.

The container 11 may have a rectangular parallelepiped shape. The plurality of chamber portions 11c are arranged in parallel. Therefore, the container 11 can be installed in a narrow installation place.

The deodorizing device 1 further includes a second cover 15 and a cover shaft 16. The second cover 15 includes a second cover opening 15a. The second cover 15 isolates a part of the plurality of chamber portions 11c from the outside air. The chamber portion of the second cover 15 that is open to the outside air is the same as the chamber portion of the first cover 14 that is open to the outside air. The cover shaft 16 rotates in synchronization with the first cover 14 and the second cover 15. Therefore, the deodorizer 10 can block both ends of each of the plurality of chamber portions 11c. The deodorizer 10 can pass gas through both ends of each of the plurality of chamber portions 11c. As a result, the deodorizing effect can be continued for a long period of time.

The deodorizing device 1 further includes a storage box 2. The storage box 2 is provided on the upper surface of the car 101 of the elevator. The storage box 2 includes a pair of box covers 2a provided on the side surfaces thereof so as to be openable and closable. The storage box 2 stores the container 11, the deodorant 12, the first cover 14, the second cover 15, and the cover shaft 16. Therefore, the deodorizing device 1 can suppress the airflow passing through the periphery of the container 11. As a result, the deodorizing device 1 can reliably feed the gas having the deodorizing effect into the inside of the car 101.

The storage box 2 acquires control information of the elevator. When the car 101 moves up or down, the storage box 2 opens the pair of covers 2a using the control information. Therefore, the storage box 2 allows the air flow to pass through the inside only when it is lifted and lowered. As a result, the deodorizing device 1 can maintain the deodorizing effect for a long time.

The pair of covers 2a may not be opened or closed. For example, the pair of cover 2a is always in an open state.

The number of the chamber portions 11c may be other than 16. When the number of the chamber portions 11c is 3 or more, the deodorizing device 1 has an effect of keeping the effective time.

The deodorizing component of the deodorizing agent 12 may not have a fragrance effect. For example, the deodorant 12 is a deodorant in which a volatile deodorant component is impregnated into porous resin beads. For example, the deodorant 12 has a component for removing malodor from the gas in contact therewith.

The first lid opening 14a may not be formed by connecting 3 of the plurality of chamber portions 11 c. For example, the first lid opening 14a is formed by connecting 2 or more of the plurality of chamber portions 11 c.

The second lid opening 15a may not be formed by connecting 3 of the plurality of chamber portions 11 c. For example, the second cover opening 15a is formed by connecting 2 or more of the plurality of chamber portions 11 c.

The deodorizer 10 may not include the second cover 15. For example, when the amount of the deodorizing component emitted from the deodorizing agent 12 is small, the deodorizing device 10 does not include the second cover 15. Specifically, when the vapor pressure of the perfume of the deodorant 12 is low, the amount of the deodorant component emitted from the deodorant 12 is small in the case where the air hardly passes through the deodorant 12 due to the small particle size.

The driving machine 20 may move the container 11. For example, the drive machine 20 moves the container 11 relatively with respect to the first cover 14. For example, the driver 20 changes the chamber in use to another chamber by moving the container 11.

The unit of the predetermined time may be other than 1 month. For example, the predetermined time period is 1 week. For example, the predetermined time period is 3 months.

Next, a first modification of the deodorizer 10 will be described with reference to fig. 9.

Fig. 9 is a diagram showing a first modification of the deodorizer of the deodorizing device of embodiment 1. Fig. 9 (a) is a plan view of the deodorizer 10 according to the first modification. Fig. 9 (B) is a B-B' cross-sectional view of fig. 9 (a).

As shown in fig. 9, in the first modification, the first cover 14 and the second cover 15, which is not shown in fig. 9, are continuously moved. For example, the first cover 14 forms an opening α of the chamber z between the chamber z belonging to the plurality of chamber portions 11 c. The opening α is a region where one end of the chamber z overlaps the first lid opening 14a during movement of the first lid 14. The area of the opening portion α is smaller than the area of one end of the chamber z.

The first cover 14 and the second cover 15 in embodiment 1 intermittently move rapidly as compared with the first cover 14 and the second cover 15 in the first modification. In the deodorizer 10 which is not a modification, the time in which the opening portion α exists is short. The time in which the opening portion α exists in the first comparative example is longer than that in embodiment 1.

In the first modification, when the new chamber z starts to open, the area of the opening α gradually increases from 0.

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

When the area of the opening α is larger than a certain value, the amount of the gas flowing in the chamber z becomes a constant value. The reason for this is that, when the value of the area of the opening α is larger than a certain area value, the conductance of the opening α is larger than the conductance of the interior of the chamber z. Conductance refers to the ease of passage of gas at a location.

For example, when the value of the area of the opening α is larger than a half of the area of one end of the chamber z, the amount of gas flowing in the chamber z is a constant saturation amount.

In the first modification of embodiment 1 described above, the first cover 14 and the second cover 15 are continuously moved. The area of the opening portion α changes comparatively with time. Therefore, the deodorizer 10 can smooth the change in the concentration of the deodorizing component in the passing gas. As a result, the deodorizer 10 can suppress abrupt changes in flavor in the passing gas.

Further, in the case where the first cover 14 and the second cover 15 are intermittently moved, the concentration of the deodorizing component emitted from the deodorizer 10 is discontinuous. In this case, the fragrance of the gas passing through the deodorizer 10 changes rapidly. In the first modification, the deodorizer 10 can suppress abrupt changes in the fragrance.

Next, a second modification of the deodorizer 10 will be described with reference to fig. 10 and 11.

Fig. 10 is a diagram showing a second modification of the deodorizer of the deodorizing device of embodiment 1. Fig. 11 is a diagram showing a case where the total concentration of the aromatic components of the deodorizing means is changed in the second modification of the deodorizing means according to embodiment 1.

As shown in fig. 10, in the second modification, 1 of the chambers that are opened in the initial state is not provided with the deodorant 12. For example, in the second modification, the chamber that is blocked after 1 month from the initial state is not provided with the deodorant 12. For example, in the second modification, the chamber a is not provided with the deodorant 12.

Fig. 11 is a graph showing the relationship between the total fragrance intensity contained in the gas passing through the deodorizing device 1 according to the second modification and the elapsed time. The vertical and horizontal axes of the graph are the same as those of the graph shown in fig. 8, which is not a modification. The value of the optimum concentration in the car is the same as that of the graph shown in fig. 8, which is not a modification.

In the graph of fig. 11, the relationship shown in the deodorizer 10 of the second modification is depicted by a solid line. The saw tooth shape of the graph of the deodorizer 10 indicates that the chamber is switching in use. The total fragrance intensity is expressed as a value of the optimum concentration in the car during a period of 2 months or more and less than 14 months from the initial state.

In the second modification, the total fragrance intensity in the initial state is 7.

In the second modification of embodiment 1 described above, 1 of the chambers that are open in the initial state is not provided with the deodorant 12. Therefore, the total fragrance intensity in the gas passing through the deodorizer 10 can be set to a value close to that in the initial state and the subsequent state. In the initial state, the total fragrance intensity can be suppressed.

In the deodorizer 10 according to the other modification, the concentration of the deodorizing component of the gas passing through in the initial state is higher than that in the second modification. In embodiment 1, the deodorizing device 10 in the initial state may give a sense of discomfort to the user due to the high-intensity fragrance emitted. In the second modification, the deodorizer 10 can suppress the intensity of the fragrance in the initial state.

Next, a third modification of the deodorizer 10 will be described with reference to fig. 12.

Fig. 12 is a diagram showing a third modification of the deodorizer of the deodorizing device of embodiment 1.

As shown in fig. 12, in the third modification, the last open chamber of the plurality of chamber portions 11c includes a deodorant 12'. The deodorant 12' contains a different deodorant component than the deodorant 12. The deodorant 12' has a different fragrance than the deodorant 12. For example, in the third modification, the chamber p includes the deodorant 12'.

In the second modification of embodiment 1 described above, the last open chamber of the plurality of chamber portions 11c includes the deodorant 12' containing a different deodorant component from the deodorant 12. Therefore, the deodorizer 10 can notify the first cover 14, not shown in fig. 12, and the second cover 15, not shown in fig. 12, that it has rotated one revolution using different fragrances. For example, maintenance personnel can know that the replacement period of the deodorant is coming.

Next, a fourth modification of the deodorizer 10 will be described with reference to fig. 13.

Fig. 13 is a diagram showing a fourth modification of the deodorizer of the deodorizing device of embodiment 1. Fig. 13 (a) is a plan view of the deodorizer 10 according to a fourth modification. Fig. 13 (B) is a C-C' sectional view of fig. 13 (a).

As shown in fig. 13, in the fourth modification, the deodorizer 10 does not include a plurality of partition surfaces 11b. In the fourth modification, the deodorizer 10 does not include a plurality of chamber portions 11c. In the fourth modification, the height direction length of the deodorizer 10 is sufficiently small with respect to the diameter of the pair of container openings 11 a. For example, in the fourth modification, the length in the height direction of the deodorizer 10 is 1-10 times the diameter of the pair of container openings 11 a.

The gas passing through the first lid opening 14a passes through a region sandwiched between the first lid opening 14a and the second lid opening 15a and the vicinity of the region in the container 11. The deodorant 12 not present in this area is not in contact with the gas outside the container. The effect of imparting the deodorizing component to the deodorizing agent 12 which is not present in this region is not reduced.

When the first cover 14 and the second cover 15 are rotated, the gas passing through the deodorizer 10 passes through the deodorizer 12 sufficiently containing a deodorizing component.

In the fourth modification, for example, the first cover 14 and the second cover 15 are intermittently moved. In the fourth modification, for example, the first cover 14 and the second cover 15 may be continuously moved.

In the fourth modification of embodiment 1 described above, the deodorizer 10 does not include a plurality of partition surfaces 11b. In the fourth modification, the height direction length of the deodorizer 10 is sufficiently small with respect to the diameter of the pair of container openings 11 a. Therefore, the gas passing through the first lid opening 14a passes through the region sandwiched between the first lid opening 14a and the second lid opening 15a and the vicinity of the region in the container 11. The deodorizer 10 can prevent the deodorizing effect of the deodorizing agent 12 that is not present in this area from being lowered. In the fourth modification, the deodorizer 10 can provide similar effects to those of the deodorizer 10 not according to the modification, without providing the plurality of chamber portions 11c.

Embodiment 2

Fig. 14 is a diagram showing a deodorizer of the deodorizing device in embodiment 2. Fig. 14 (a) is a perspective view of the deodorizer. Fig. 14 (B) is a plan view of the deodorizer. Fig. 14 (C) is a diagram showing a case where a pair of sheets are peeled off. Fig. 14 (D) is a D-D' sectional view of fig. 14 (B). The same or corresponding parts as those of embodiment 1 are denoted by the same reference numerals. The description of this portion is omitted.

In embodiment 2, the number of chambers in use increases with the passage of time.

As shown in fig. 14, the deodorizing device 1 includes a deodorizer 30 inside the storage box 2.

The deodorizer 30 includes a container 31, a deodorizer 12, a screen 33, a pair of sheets 34, and a stripper 35.

For example, the container 31 has a rectangular parallelepiped shape. The container 31 has a hollow inside. For example, the container 31 includes a pair of container openings 31a, a plurality of partition surfaces 31b, and a plurality of chamber portions 31c.

The pair of container openings 11a are provided on a pair of opposite side surfaces of the container 31. For example, the pair of container openings 31a corresponds to the entirety of each of the pair of side surfaces in the container 31.

The plurality of partition surfaces 31b are provided in the container 31. The plurality of partition surfaces 31b are provided from one to the other of the pair of container openings 31 a. For example, the plurality of partition surfaces 31b are provided perpendicularly to the pair of container openings 31 a. For example, the pair of container openings 31a are provided parallel to each other. The plurality of partition surfaces 31b divide the interior of the container 31. For example, the plurality of partition surfaces 31b are provided with 5 pieces. For example, the plurality of dividing surfaces 31b equally divide the interior 6 of the container 31.

The plurality of chamber portions 31c are regions of the interior of the container 31 partitioned by the plurality of partition surfaces 31 b. Each of the plurality of chamber portions 31c has a columnar shape with the pair of container openings 31a as a bottom surface. For example, each of the plurality of chamber portions 31c has a rectangular cross section. For example, 6 chamber portions 31c are provided in the container 31. For example, the plurality of chamber portions 31c are arranged in parallel.

For example, the deodorant 12 is the same deodorant as embodiment 1.

For example, the plurality of screens 33 have a mesh structure. The plurality of screens 33 are provided at both ends of each of the plurality of chamber portions 31 c. A plurality of screens 33 pass the gas. The plurality of screens 33 block the deodorant 12 from leaking out of the plurality of chamber portions 31c, respectively.

For example, each of the pair of sheets 34 has a rectangular shape. The pair of sheets 34 each include an adhesive 34a. The pair of sheets 34 are detachably adhered to the pair of container opening portions 31a by an adhesive 34a. The pair of sheets 34 isolate the plurality of chamber portions 31c blocked by the pair of sheets 34 from the gas outside the container 31.

For example, the stripper 35 is provided on the side of the container 31. For example, the stripper 35 is connected to one end of each of the pair of sheets 34. For example, the stripper 35 pulls one end of each of the pair of sheets 34. The stripper 35 separates the pair of sheets 34 from the container 31. The stripper 35 controls the stripping position of each of the pair of sheets 34.

The deodorizer 30 increases the number of chambers in use by peeling the pair of sheets 34 apart. The deodorizer 30 increases the number of chambers in use per certain time.

According to embodiment 2 described above, the container 31 has a rectangular parallelepiped shape. The plurality of chamber portions 31c are arranged in parallel. Therefore, the container 31 can be installed in a narrow installation place.

The deodorizing device 1 further includes a pair of sheets 34. The pair of sheets 34 are detachably adhered to the pair of container opening portions 31a. Thus, the deodorizer 30 can use a new deodorizer 12 every certain time. As a result, the deodorizing device 1 can maintain the deodorizing effect for a long time.

In addition, in the change in the intensity and the property of the fragrance generated by the deodorizer 30, as shown in embodiment 1, the influence of the highly volatile deodorizing component is greater than the influence of the less volatile component. Therefore, in the case of using a new deodorant 12, the deodorizer 30 can maintain the deodorizing effect constant without sealing the chamber for a long period of use.

The shape of the container 31 is not limited to a rectangle. For example, the container 31 has the same shape as the container 11 of embodiment 1. In this case, the pair of pieces 34 are each circular. For example, the pair of pieces 34 has radial cuts. The pair of sheets 34 peel the region of 1 of the plurality of chamber portions 11c along the slit at a predetermined time.

The deodorizer 30 may not include the peeler 35 as long as the pair of sheets 34 can be peeled off each time. For example, the deodorizer 30 is not provided with a stripper 35. For example, a maintenance person performs a work of separating the pair of sheets 34 at a predetermined time.

The deodorizer 30 may not have a pair of plates 34 as long as the chamber in use increases with the passage of time. For example, the deodorizer 30 includes a container 11, not shown in fig. 14, which is not a modification, instead of the container 31. For example, the first cover 14 not shown in fig. 14 and the second cover 15 not shown in fig. 14 have a fan-like structure. For example, the first cover 14 enlarges a first cover opening 14a, which is not shown in fig. 14, with the passage of time. For example, the second cover 15 enlarges a second cover opening 15a, which is not shown in fig. 14, with the passage of time.

Embodiment 3

Fig. 15 is a diagram showing a deodorizing device according to embodiment 3. Fig. 16 is a diagram showing a driving machine of the deodorizing device in embodiment 3. The same or corresponding parts as those of embodiment 1 or embodiment 2 are denoted by the same reference numerals. The description of this portion is omitted.

As shown in fig. 15, in embodiment 3, the deodorizing device 1 includes a driving machine 40.

The driving machine 40 is provided with a propeller 41.

The propeller 41 is provided with a propeller fan 41a. For example, the propeller 41 is rotatably provided above the storage box 2. For example, the propeller 41 is provided above one of the pair of case covers 2 a.

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

The propeller 41 rotates by using the air flow generated near the car 101 when the car 101 is lifted or lowered. This airflow is observed from the car 101 when the car 101 moves relative to the hoistway 100. In the case where the car 101 is ascending, the air flow is a descending air flow with respect to the car 101. In the case where the car 101 descends, the airflow is an ascending airflow with respect to the car 101.

The propeller 41 is rotated by receiving the airflow in the propeller fan 41a. For example, when the car 101 is lifted, the propeller 41 rotates in the forward direction. For example, when the car 101 descends, the propeller 41 rotates in the opposite direction.

As shown in fig. 16, the driver 40 includes a propeller 41, a first gear 42, a second gear 43, an escape wheel 44, an escape fork 45, a pawl 46, and a pair of stoppers 47. For example, the driving machine 40 is connected to the storage box 2. The drive machine 40 rotates the cover shaft 16.

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 in synchronization with the rotation of the propeller 41.

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 provided so as to mesh with the first gear 42. For example, the second gear 43 forms a helical gear together with the first gear 42. For example, the rotation axis of the second gear 43 is parallel to the cover shaft 16.

The escape wheel 44 has a disc shape. The escape wheel 44 includes a plurality of protrusions 44a on the outer peripheral surface. The escape wheel 44 is connected to the cover shaft 16. The central axis of escape wheel 44 is coaxial with cover shaft 16. For example, escape wheel 44 rotates in synchronization with the rotation of cover shaft 16.

One end of the pallet 45 has a double-fork shape. The pallet 45 has a pair of pallets 45a at one end. The pallet fork 45 is rotatably connected to the shaft 45b at a position of a root portion of the pallet fork. The other end of the pallet 45 is connected to the rotation shaft of the second gear 43. The pallets 45 are arranged in such a way that the escape wheel 44 is located between the pallets. The pallet 45 is provided at a position where the pair of pallets 45a can contact the plurality of protruding bodies 44a.

The pallet 45 is rotatably provided around a shaft 45b. The pallet fork 45 is supplied with rotational driving force from the second gear 43. For example, when the second gear 43 rotates in the forward direction, one end of the pallet 45 moves in one direction. When one end of the pallet 45 moves in one direction, the other end of the pallet 45 moves in the other direction. For example, when the second gear 43 rotates in the opposite direction, one end of the pallet 45 moves in the other direction. When one end of the pallet 45 moves in the other direction, the other end of the pallet 45 moves in the one direction.

The pair of tiles 45a applies an external force to the plurality of protrusions 44a from only one direction. When the pair of tiles 45a comes into contact with 1 of the plurality of protruding bodies 44a from the other direction, the pair of tiles 45a does not move the position of the protruding body 44 a. The pair of tiles 45a moves in the other direction without moving the position of the protruding body 44 a.

For example, the claw 46 has a rod-like shape. One end of the claw 46 is connected to the center of the second gear 43. The claw 46 moves in a pendulum shape centering on one end. The pawl 46 moves in synchronization with the rotation of the second gear 43.

One of the pair of stoppers 47 is provided on one side of the claw 46. One of the pair of stoppers 47 is provided on the other side of the claw 46. A pair of stoppers 47 are provided respectively so as to be able to interfere with the movement of the claws 46. A pair of stoppers 47 respectively define the amplitude by which the claws 46 can move. For example, when the claw 46 moves to one side, one of the pair of stoppers 47 stops the movement of the claw 46 by collision.

The drive machine 40 rotates the cover shaft 16 using an air flow generated by the lifting and lowering movement of the car 101. The driver 40 moves the first cover 14 and the second cover 15 through the cover shaft 16. The drive machine 40 changes the relative positions of the first cover 14 and the second cover 15 and the container 11.

For example, when the car 101 is lifted, the drive machine 40 rotates the cover shaft 16 clockwise. For example, when the car 101 descends, the drive machine 40 does not rotate the cover shaft 16.

For example, in the case where the car 101 is ascending, the propeller 41 receives a descending air flow. When receiving the downdraft, the propeller 41 rotates in the forward direction. The first gear 42 rotates in the forward direction in synchronization with the propeller 41. The second gear 43 rotates in the forward direction in synchronization with the first gear 42. The pallet fork 45 is applied with a rotational driving force by the second gear 43. One end of the pallet 45 moves in one direction. The pair of tiles 45a applies an external force to 1 of the plurality of protruding bodies 44a from one direction. The escape wheel 44 rotates in the forward direction. The cover shaft 16 rotates clockwise in synchronization with the rotation of the escape wheel 44.

For example, when the car 101 descends, the cover shaft 16 does not rotate. When the car 101 descends, one end of the pallet 45 moves in the other direction. The pair of tiles 45a is in contact with 1 of the plurality of protrusions 44a from a plurality of directions. The pair of tiles 45a moves in the other direction without moving the position of the protruding body 44 a.

According to embodiment 3 described above, the driving machine 40 includes the propeller 41. The propeller 41 is disposed above the car 101 of the elevator. The propeller 41 is rotatably provided in the driving machine 40. The propeller 41 rotates by the airflow generated around the car 101 when the car 101 moves up or down. The driving machine 40 uses the driving force of the rotation 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 providing electric power equipment.

Further, the pair of tiles 45a may be provided so as to apply an external force to the plurality of protruding bodies 44a only from the other direction.

Industrial applicability

As described above, the deodorizing device of the present invention can be used for a deodorizing device of an elevator.
