Description

  The present invention relates to a deodorization system.

  As a conventional device for deodorizing a odor in a living room or the like, there is a device that blows out an air current in a state where a fragrance component generated from a fragrance is mixed with an air current generated by a fan or the like and diffuses the fragrance component into the living room or the like (See Patent Document 1).

Japanese Patent No. 4865421

  The apparatus described in Patent Document 1 deodorizes odors existing in a specific space by diffusing a fragrance component at a certain rate in a living room or the like. In the apparatus described in Patent Document 1, since the amount of diffusion is constant, it cannot cope with a change in the environment in the space. For example, when the amount of odor in the space greatly exceeds the fragrance component, an unpleasant space is formed by the odor. On the other hand, when only the fragrance component is diffused even though there is almost no odor, the fragrance component becomes conspicuous and an unnatural space is formed.

  Then, an object of this invention is to provide the deodorizing system which can respond to the change of an environment.

  The deodorization system includes a deodorant medium that deodorizes the odor contained in the environmental air, a deodorizer that supplies the environment, a detection unit that detects a change in the environment, and a detection result by the detection unit. And a control unit for changing an operation mode of the deodorizer.

  According to the deodorization system, the operation mode is changed in accordance with a change in the environment, so that the operation of the deodorizer that matches the change in the environment can be realized.

It is a figure which shows schematic structure of the deodorizing system of this embodiment. It is a perspective view of a deodorizer. It is a disassembled perspective view of a deodorizer. It is a figure which shows a mode that air is inhaled into both the rooms in a deodorizer. It is a figure which shows a mode that air is sucked into one room in a deodorizer. It is a flowchart which shows the flow of operation | movement of a deodorizing system.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted. In addition, the dimensional ratios in the drawings are exaggerated for convenience of explanation, and may be different from the actual ratios.

  FIG. 1 is a diagram illustrating a schematic configuration of a deodorizing system according to the present embodiment.

  The deodorization system 1 includes a deodorizer 10, a detection unit 20, and a control unit 30.

  The deodorizer 10 is installed in an environment where the deodorizing system 1 is applied. The deodorizer 10 has a deodorant inside, generates a deodorant medium from the deodorant by an air flow taken from the environment, and supplies the deodorant medium to the environment. The deodorizing medium is formed of a material that exhibits an action of deodorizing odors. The deodorizing medium is not particularly limited as long as the odor can be deodorized. For example, at least one of a deodorizing component, an aromatic component, ions, and ozone can be included. These deodorizing media may be used alone or, for example, a deodorizing component and an aroma component can be used in combination. As a deodorization method using a fragrance, either a masking method or a pairing deodorization method can be adopted. The masking method is a method for canceling the odor with a relatively strong scent, and the pairing deodorization method is a method for deodorizing the odor with a relatively light scent.

  In this specification, the term “deodorization” includes not only literal deodorization but also deodorization and deodorization, which reduces odors that people feel unpleasant or eliminates them to the extent that they do not feel uncomfortable. It is used as a broad word to change to a type that does not feel uncomfortable.

  The detailed configuration of the deodorizer 10 will be described later.

  The detection unit 20 detects a change in the environment. In the present embodiment, the detection unit 20 is a camera that can monitor the environment to which the deodorizing system 1 is applied. The detection unit 20 acquires an image in the environment using a lens and transmits the acquired image to the control unit 30.

  The control unit 30 controls the deodorizer 10 and the detection unit 20. The control unit 30 controls the operation mode of the deodorizer 10 based on the detection result by the detection unit 20. In the present embodiment, the control unit 30 determines the number of people in the environment from the image detected by the detection unit 20. The control unit 30 sequentially analyzes the images transmitted from the detection unit 20 and detects the number of people in the images. In the image analysis, for example, a human face is recognized, and the number of recognized faces is determined as the number of people in the environment. The image analysis method is not limited to face recognition. For example, it is also possible to determine a person by extracting features such as an object that moves in an image, an object having a certain size, an object having a certain shape, and a luminance gradient. Any human detection method currently used can be applied to this embodiment.

  The control unit 30 monitors changes in the number of people in the environment as environmental changes, and controls the deodorizer 10 based on the changes. Specific operations by the control unit 30 will be described later. Before describing the operation of the control unit 30, the structure of the deodorizer 10 will be described.

  FIG. 2 is a perspective view of the deodorizer, and FIG. 3 is an exploded perspective view of the deodorizer.

  As shown in FIGS. 2 and 3, the deodorizer 10 includes a housing 12, a rotary intake unit 14, a fan 16, and an upper lid 18.

  The housing 12 holds the cylindrical rotary intake portion 14 rotatably. The housing 12 includes a partition wall 120 that partitions the rotary intake section 14 when the rotary intake section 14 is held. In the present embodiment, the partition wall 120 divides the rotary intake section 14 into two rooms. A deodorant 40 is disposed in one of the rooms partitioned by the partition wall 120. In this embodiment, nothing is arranged in the other room.

  The rotary intake portion 14 is formed with a plurality of suction holes 140 through which air can pass over a half circumference of the cylindrical side surface. The rotary intake unit 14 may include a filter that can adsorb and capture dust and particles such as a nonwoven fabric inside the cylinder in which the suction hole 140 is formed. The rotary intake portion 14 has a circular shaft hole 144 formed in the top portion 142. When the shaft hole 144 fits into the cylindrical protrusion 122 formed on the top of the partition wall 120 of the housing 12, the rotary intake portion 14 can rotate around the protrusion 122. The rotary intake unit 14 is connected to a motor in the casing 12 (not shown), and the rotation direction and the rotation amount can be determined by driving the motor. In addition to the shaft hole 144, a vent hole 146 serving as an air flow path is also formed in the top portion 142 of the rotary intake portion 14.

  The fan 16 is provided so as to be positioned on the top 142 of the rotary intake unit 14. The fan 16 has a rotating blade 162. When the rotary blade 162 rotates, an air flow is formed in a direction in which air is sucked from the rotary intake section 14. The fan 16 is accommodated in the upper lid 18.

  The upper lid 18 has a plurality of exhaust holes 182 in accordance with the exhaust position of the airflow formed by the stored fan 16.

  As described above, the deodorizer 10 sucks air into the housing 12 from the periphery of the rotary intake portion 14 by the rotation of the fan 16 and exhausts it to the upper surface of the upper lid 18. The air sucked into the housing 12 passes through at least one of the two rooms separated by the partition wall 120 in the housing 12 and is discharged from the vent hole 146 to the fan 16. Here, the reason for passing through at least one of the rooms is that the air flow path is switched depending on the position of the rotary intake section 14.

  The switching of the air flow path will be described in more detail.

  FIG. 4 is a diagram showing how air is sucked into both rooms in the deodorizer, and FIG. 5 is a diagram showing how air is sucked into one room in the deodorizer. 4 and 5 show the deodorizer 10 when the top cover 18 is viewed as a plane. For the sake of explanation, the illustration of the configuration other than the rotary intake portion 14 and the partition wall 120 of the housing 12 is omitted. Yes. 4 and 5, the range in which the suction hole 140 of the rotary intake section 14 is formed, that is, the range in which air can flow is indicated by double arrows.

  As shown in FIG. 4, when the range in which the suction hole 140 is disposed straddles the partition wall 120, air flows into the two chambers on both sides of the partition wall 120 from the suction hole 140. On the other hand, as shown in FIG. 5, when the range in which the suction hole 140 is disposed extends to only one of the rooms separated by the partition wall 120, air is introduced into one room and air is introduced into the other room. Not inflow. In the example shown in FIG. 5, air flows only into the room where the deodorant 40 is disposed.

  As described above, the air flow path can be appropriately changed by rotating the rotary intake portion 14 and changing the position where the suction hole 140 is disposed. FIG. 4 shows a case where air flows in half (50%) into the room where the deodorant 40 is arranged and the room where the deodorant 40 is not arranged. In FIG. (100%), the case where air flows in is shown. However, by adjusting the position of the rotary intake portion 14, that is, the range in which the suction hole 140 is disposed, the ratio of the inflow of air into the room in which the deodorant 40 is disposed can be adjusted to 0 to 100%. Hereinafter, the position of the rotary intake section 14 is adjusted so that the ratio of the air flowing into the room where the deodorant 40 is disposed is X%. ".

  By adjusting the amount of air passing through the room where the deodorant 40 is present, the amount of the deodorizing medium dispersed by vaporization or the like from the deodorant 40 can be adjusted, and as a result, the deodorizer 10 supplies the environment. The amount of deodorizing medium to be adjusted can be adjusted.

  Next, the operation of the deodorizing system 1 will be described.

  FIG. 6 is a flowchart showing a flow of operation of the deodorization system. In this embodiment, it is assumed that the deodorizing system 1 is installed in a cigarette smoking space.

  The detection part 20 detects the person who exists in the environment where the deodorizing system 1 was installed as a detection of the change of an environment (step S101).

  The control unit 30 specifies the number of people (parameters) from the people detected by the detection unit 20 (step S102), and changes the operation mode according to the specified number of people (step S103). In the present embodiment, the change in the operation mode is a change in the position of the rotary intake unit 14 of the deodorizer 10. For example, it is assumed that the smoking space can accommodate 10 people. The deodorant medium that the deodorizer 10 supplies into the environment when 100% air is supplied to the deodorant 40 is just to deodorize the odor that is generated when 10 people smoke in the environment. Consider the case. That is, the components of the deodorant 40 and the odor when the 10 people smoke in the smoking space can be deodorized by the deodorant medium generated when 100% air is supplied to the deodorant 40. Consider the case where the size, the inflow of air, etc. are set in advance. In this case, when the number of persons detected by the detection unit 20 is two (parameters), the control unit 30 controls the position of the rotary intake unit 14 so as to supply 20% air to the deodorant 40. . Similarly, when the detected number of people is 5, as shown in FIG. 4, the position of the rotary intake unit 14 is controlled so that 50% of air is supplied to the deodorant 40.

  According to the deodorizing system 1 in the present embodiment, the following effects are obtained.

  As described above, in the present embodiment, the position (operation mode) of the rotary intake unit 14 is changed in accordance with a change in the number of people in the environment (change in the environment). In a smoking space, there is a high probability that the person to be detected is smoking, and the amount of smoke emitted from the tobacco, that is, the amount of odor can be estimated. Therefore, the deodorizing system 1 can adjust the amount of the deodorizing medium supplied to the environment to be small if the number of people in the environment increases and the amount of the deodorizing medium supplied to the environment to be small if the number is small. Further, if no one is detected, the amount of deodorizing medium supplied to the environment can be made zero. Therefore, it is possible to always balance the amount of odor and deodorizing medium in the environment. Thereby, the odor in an environment can be deodorized with a required amount of deodorizing media. A certain deodorizing effect can be obtained. Further, the deodorant 40 is economically consumed without being unnecessarily consumed. In addition, even if the deodorizing medium has a scent, the scent is not supplied more than necessary to the environment, and the presence of the deodorizing medium does not stand out unnaturally.

(Modification of detection unit)
In the above embodiment, the detection unit 20 is a camera, and the change in the amount of odor in the environment is indirectly detected by the number of people in the environment. However, the detection unit 20 can also detect a change in the amount of odor indirectly or directly by a configuration other than the camera.

  The following modified examples 1 to 5 are modified examples of the detection unit 20 that directly detects a change in the amount of odor by detecting the odor itself in the environment.

  Modifications 6 to 10 are modifications of the detection unit 20 that indirectly detects a change in the amount of odor by detecting the source of odor in the environment.

  The modified examples 11 to 18 are modified examples of the detection unit 20 that indirectly detects a change in the amount of odor by detecting a person in the environment.

  Below, the modifications 1-18 of the detection part 20 are demonstrated.

(Modification 1 of a detection part)
In the first modification, the detection unit 20 is an odor sensor that detects the odor itself. Specifically, the odor sensor detects a change in the amount of odor based on, for example, a change in dielectric constant of a metal oxide element or an organic semiconductor film element or a change in frequency of a crystal resonator. In addition, the odor sensor may detect odor by any method.

(Modification 2 of the detection unit)
In the modification 2, the detection part 20 is a smoke sensor which detects the smoke with an odor. Specifically, the smoke sensor can confirm the presence and amount of smoke by checking the light transmittance in the environment with infrared rays or the like. The control unit 30 can specify the amount of odor from the amount of smoke. However, any other commonly used smoke sensor can be applied to the detection unit 20.

(Modification 3 of the detection unit)
In the modification 3, the detection part 20 is a sensor which detects the component contained in an odor. Specifically, for example, when the cause of odor is tobacco smoke, the amount of a component derived from tobacco and scattered in the air is detected. Examples of tobacco-derived components include acetaldehyde, arololein, pyridine, cyclic aromatic hydrocarbons, nicotine, 1,3-butadiene, benzene, toluene, carbon dioxide and the like. The control unit 30 can identify the amount of odor by detecting the amount of tobacco-derived components in the environment.

  Furthermore, since the detection part 20 detects the component derived from tobacco, the control part 30 can also identify the kind of tobacco by analyzing the detected component.

(Modification 4 of the detection unit)
In the modification 4, the detection part 20 is a temperature sensor. The detection part 20 detects the temperature rise by smoke. The control unit 30 has a correlation table between the temperature rise and the amount of odor (the amount of smoke) in advance, and the odor amount can be specified by referring to the table. In this case, it is preferable that the detection unit 20 is disposed at a position where the smoke hits by an air current or the like.

(Modification 5 of the detection unit)
In the modification 5, the detection part 20 is a humidity sensor. The detection unit 20 detects an increase in humidity due to the steam contained in the smoke. The control unit 30 has a correlation table between the increase in humidity and the amount of odor (amount of smoke), and the amount of odor can be specified by referring to the table. In this case, it is preferable that the detection unit 20 is disposed at a position where the smoke hits by an air current or the like.

(Modification 6 of the detection unit)
In the modification 6, the detection part 20 detects tobacco as a generation source of smoke. The detection unit 20 detects the burning portion at the tip of the cigarette by infrared rays, for example, using the principle of infrared thermography. In this case, the number of detected burning portions corresponds to the number of cigarettes being burned. If you measure (determine) in advance the amount of odor generated from a single cigarette during combustion, you can indirectly identify the amount of odor in the environment by multiplying that amount of odor by the number of cigarettes detected. it can. In the case of an electronic cigarette, the burning or heating of the cigarette may occur in the housing. In this case, the detection unit 20 detects the heat generation of the housing.

(Modification 7 of the detection unit)
In the modified example 7, the detection unit 20 detects the number of cigarette butts. In this case, the detection unit 20 is, for example, an infrared sensor or a weight sensor installed in the ashtray.

  When the detection unit 20 is an infrared sensor, a light emitting unit and a light receiving unit are provided in the middle of the fall of the butts put in the ashtray. The number of the butts can be detected by counting the number of times that the falling butts block infrared rays and the light receiving part stops receiving light. If the odor amount generated from one cigarette is measured in advance, the odor amount in the environment can be indirectly specified by multiplying the odor amount by the number of cigarette butts detected.

  When the detection unit 20 is a weight sensor, the number of butts can be specified by detecting an increase in the weight of the ashtray. In this case, if the average weight of the butts is measured (determined) in advance, the number of butts can be specified by dividing the weight increase by the average weight of the butts.

(Modification 8 of the detection unit)
In the modification 8, the detection part 20 detects the light emission part of an electronic cigarette. In this case, the detection unit 20 is a camera that can recognize an image. In general, an electronic cigarette lights up a part of a housing at a timing such as when smoking is possible and when smoking is finished during preparation for smoking. By detecting the lighting, tobacco can be detected. By multiplying the number of lights by the amount of odor generated from one cigarette, the amount of odor in the environment can be indirectly specified. Alternatively, if the lighting pattern is different, such as during smoking preparation, when smoking is possible, when the smoking is finished, or when the lighting pattern is different (such as blinking), the amount of odor generated should be measured (decided) in advance for each lighting pattern. The amount of odor can be specified with higher accuracy.

(Modification 9 of the detection unit)
In the modification 9, the detection part 20 is a communication apparatus which can communicate with the housing | casing of an electronic cigarette. The detection unit 20 can detect cigarettes in the environment by communicating with the casing of the electronic cigarette.

(Modification 10 of the detection unit)
In the modification 10, the detection part 20 detects the charge number of the housing | casing of an electronic cigarette. The detection unit 20 is provided in a charger for the case of the electronic cigarette, and detects power supply to the charger. Since the number of chargers can be estimated as the number of cigarettes (or the number of people), the detection unit 20 can detect the cigarettes in the environment although it is provisional.

(Modification 11 of the detection unit)
In the modification 11, the detection part 20 detects a person like the said embodiment. The detection unit 20 detects the number of people using infrared rays, for example, using the principle of infrared thermography. In this case, the control unit 30 can indirectly specify the amount of odor in the environment by multiplying the number of people by the amount of odor generated by one person smoking a cigarette.

  The detection unit 20 may be a camera. In this case, the detection unit 20 captures an image in the environment as a change in environment with the camera. The control unit 30 determines whether there is a person in the image based on the image detected by the camera. For example, the control unit 30 can recognize a person's face from an image, or can recognize a person's body from the outer shape and size of a person's limbs. The control unit 30 can also specify the number of people by extracting and emptying people from the image.

(Modification 12 of the detection unit)
In the modification 12, the detection part 20 is an infrared sensor provided in the environment (smoking space). The infrared sensor includes a pair of a light emitting unit and a light receiving unit. Two sets of infrared sensors are provided, for example, in two rows outside and inside the entrance of the smoking space. In a set outside the smoking space, light reception by the light receiving unit is blocked, and within a predetermined time (for example, 1-2 seconds), if light reception by the light receiving unit is blocked in the set inside the smoking space, You can detect that you have entered the room. On the other hand, if a block occurs first in the inner set and then blocks in the outer set, then it can be detected that the person has left the room. In this way, the number of people in the environment can be monitored by detecting entry / exit. The control unit 30 can indirectly specify the amount of odor in the environment by multiplying the number of people in the environment by the amount of odor generated by one person smoking a cigarette.

(Modification 13 of the detection unit)
In the modified example 13, the detection unit 20 is a non-contact heart rate sensor that detects a pulse group from the skin blood flow on the body surface using a camera or measures a pulse by applying radio waves to the human body. The detection unit 20 can detect the number of people in the environment by detecting the number of human heartbeats. The control unit 30 can indirectly specify the odor amount in the environment by multiplying the detected number of persons by the odor amount generated when one person smokes a cigarette.

(Modification 14 of the detection unit)
In the modification 14, the detection unit 20 is an odor sensor. The detection unit 20 detects a human-derived odor, for example, a sweat or fat odor. The control unit 30 can indirectly identify the amount of odor in the environment by estimating the number of people in the environment from the amount of human-derived odor and multiplying the amount of odor generated by one person smoking a cigarette. .

(Modification 15 of the detection unit)
In the modified example 15, the detection unit 20 is a weight sensor such as a piezoelectric element, for example. In this case, the detection unit 20 is embedded in the floor. By detecting the person who is stepping on the floor, the number of people in the environment can be detected. The control unit 30 can indirectly specify the odor amount in the environment by multiplying the detected number of persons by the odor amount generated when one person smokes a cigarette.

(Modification 16 of the detection unit)
In the modification 16, the detection part 20 is an electromagnetic wave measuring device. In recent years, most people have mobile terminals such as mobile phones, smartphones, and tablets. Since electromagnetic waves are generated from the mobile terminal, the detection unit 20 detects the electromagnetic waves. The control unit 30 can estimate the number of detected electromagnetic waves as the number of people in the environment.

(Modification 17 of the detection unit)
In the modified example 17, the detection unit 20 is a sound level meter. The detector 20 measures the noise level in the environment. The control unit 30 can estimate the number of people in the environment based on a noise level prepared in advance and a correlation table of the number of people in the environment.

(Modification 18 of the detection unit)
In the modification 18, the detection unit 20 is a camera and detects at least one of the sex and age of a person in the environment. Specifically, the detection unit 20 captures an image in the environment. The control unit 30 determines whether there is a person in the image based on the image detected by the camera. For example, the control unit 30 can recognize a person's face from an image, or can recognize a person's body from the outer shape and size of a person's limbs. The control unit 30 further analyzes features from the recognized person's face and body, and identifies (estimates) at least one of the recognized person's gender and age.

  As in the above-described modified examples 1 to 18, in addition to the embodiment, various types of detection units 20 can be applied to the present invention.

  In the above embodiment and Modifications 1 to 18, the detection unit 20 detects a change in the environment, and the control unit 30 analyzes the change in the environment to specify the number of cigarettes, the number of people, and the like. However, the present invention is not limited to this, and a processing function may be mounted on the detection unit 20 and the detection unit 20 may specify the number of cigarettes, the number of people, and the like.

(Modification of operation mode of deodorizer)
Next, a modified example of the operation mode of the deodorizer 10 will be described.

  In the said embodiment, the control part 30 adjusted the quantity of the deodorizing medium supplied to an environment by changing the ratio of the air supplied to the deodorizer 40 as a change of an operation mode. However, the control part 30 can adjust the quantity of a deodorizing medium with another form, and can change another element as a change of an operation mode.

  Below, the modification AC of the operation mode of the deodorizer 10 by the control part 30 is demonstrated.

(Modification A of the deodorizer operation mode)
In the modified example A, as the change of the operation mode, the amount (concentration) of the deodorizing medium supplied to the environment is adjusted as in the above embodiment. However, in the modification A, the ratio of the air supplied to the deodorant 40 is not changed as in the embodiment. In the modified example A, two rooms are not provided in the deodorizer 10, but only one room is provided, and a deodorant is disposed in the one room. That is, if air is sucked from the suction hole, 100% of the air is surely exhausted to the outside of the deodorizer 10 after passing through the room where the deodorant is disposed. On the other hand, in Modification A, unlike the above embodiment, the rotation of the fan 16 is variable.

  The rotational speed of the fan 16 is changed according to the detection result by the detection unit 20. For example, it is assumed that the deodorizing system 1 is arranged in a smoking space. When the number of smoking spaces that can be accommodated is 10 and no one is identified from the detection result, the control unit 30 stops the rotation of the fan 16 of the deodorizer 10. That is, the control unit 30 does not supply the deodorizing medium to the environment. On the other hand, when 10 persons are specified, the control unit 30 maximizes the number of rotations of the fan 16 per unit time. As a result, the control unit 30 can generate the maximum amount of deodorizing medium and supply it to the environment when the number of people that can be accommodated is maximum and the odor is greatest. When five persons are specified, the control unit 30 sets the rotation speed of the fan 16 per unit time to a maximum of 50%.

  Thus, the amount of the deodorizing medium supplied to the environment can be changed by changing the number of rotations of the fan 16 and changing the amount of air supplied to the deodorizer in the deodorizer 10.

  Alternatively, when the cigarette butts are detected by the detection unit 20, the control unit 30 increases the rotation speed of the fan 16 by 10% of the maximum rotation speed per unit time for each predetermined time for each detection of the butts. Also good. Here, the predetermined time is, for example, a time during which a deodorizing medium that balances the odor generated from one cigarette is generated. If the butts are continuously detected before the predetermined time elapses, the rotational speed of the fan 16 per unit time increases by 10% of the maximum rotational speed. Thereby, even when the odor increases continuously, the amount of the deodorizing medium supplied to the environment can be increased in proportion, and the odor can be deodorized by the balanced amount of the deodorizing medium.

(Modification B of deodorizer operation mode)
In the modified example B, as the operation mode change, the supply direction of the deodorant medium is changed so that the deodorant medium is directed to a position where the amount of odor is large. In order to change the supply direction of the deodorizing medium, the deodorizer 10 has a movable splash (not shown) in the vicinity of the discharge hole. The angle (attitude) of the movable slat can be changed by the control unit 30. For example, when honey stands perpendicular to the upper lid 18, the deodorizing medium is supplied directly above the upper lid 18. Moreover, when it inclines 30 degree | times with respect to the upper cover 18, a deodorizing medium is supplied to a 30 degree diagonal direction. The upper lid 18 itself may be rotated 180 degrees horizontally. If comprised in this way, if it is the range of a hemisphere seeing from the upper cover 18, a deodorizing medium can be supplied to any direction. The movable hood and the upper lid 18 can be freely rotated by being connected to a motor via a gear or the like.

  For example, when the infrared sensor can be scanned in the environment and the smoke position can be identified as in the second modification, the control unit 30 may supply the deodorizing medium toward the identified smoke position. In addition, the rotational position of the movable flap and the upper lid 18 is controlled. Thereby, the odor contained in smoke can be deodorized reliably and efficiently.

  Alternatively, even when the detection unit 20 is a sensor such as the first modification or the third modification, if the detection unit 20 is arranged at a plurality of different positions in the environment, the control unit 30 may generate odor (smoke). You can identify the gathering place. If the position of the odor can be specified, the change of the operation mode of the modified example B can be effectively utilized.

(Modification C of deodorizer operation mode)
In the modified example C, the type of the deodorizing medium supplied by the deodorizer 10 is changed as the operation mode change. In order to change the type of the deodorizing medium, the deodorizer 10 has a plurality of rooms as in the above embodiment. In the embodiment, the deodorant 40 is disposed in one of the two rooms. However, in Modification C, different types (scents) of deodorant are disposed in different rooms. And the control part 30 can supply a deodorizing medium of a different kind to environment by changing the room where the air attracted | sucked from the suction hole 140 passes. The room through which air passes can be changed by changing the position of the rotary intake section 14 as in the embodiment.

  Specifically, for example, a four-divided room having a central angle of 90 degrees is provided in the rotary intake section 14, and a suction hole 140 is provided in the range of 90 degrees on the circumference of the rotary intake section 14. Suppose that In this case, the position of the rotary intake portion 14 can be determined so that the suction hole 140 faces only one of the rooms.
