[0009] Preferred embodiments of the present disclosure will be described in detail below with reference to the drawings. Elements common to the embodiments and modifications described below are designated by the same reference numerals, and redundant descriptions of the common elements may be omitted. The following embodiment is merely one of various embodiments of the present disclosure. Various modifications of the embodiment may be made depending on the design, etc., as long as the object of the present disclosure can be achieved. The following embodiments and modifications may also be realized in appropriate combinations.

[0010] The drawings described in this disclosure are schematic diagrams, and the ratios of the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensional ratios. Note that the arrows indicating the directions in the drawings are merely examples and are not intended to define the directions when using the ventilation system 1. Furthermore, the arrows indicating the directions in the drawings are merely shown for the purpose of explanation and do not have any substance.

[0011] In this disclosure, "orthogonal (perpendicular)" refers not only to a state where the angle between two things is exactly 90 degrees, but also to a state where two things intersect within a certain range of difference. In other words, the angle between two orthogonal things is within a certain range of difference from 90 degrees (for example, 10 degrees or less). In other words, "orthogonal" in this disclosure includes a case where the angle between two things is between 80 degrees and 100 degrees. Similarly, "parallel" in this disclosure includes not only a case where two things do not strictly intersect, but also a case where two things are lined up within a certain range of difference. For example, "parallel" in this disclosure includes a case where one thing is inclined at an angle of 10 degrees or less relative to the other. In other words, "parallel" in this disclosure includes a case where the angle between one thing and the other is between -10 degrees and 10 degrees.

[0012] (1) Overview First, an overview of a ventilation system 1 according to this embodiment will be described with reference to FIG.

[0013] As shown in FIG. 1, the air blowing system 1 of this embodiment includes a first airflow section 4 and a second airflow section 5.

[0014] The first airflow section 4 generates a first airflow A1.

[0015] The second airflow section 5 merges the second airflow A2 to which the functional ingredient has been added with the first airflow A1.

[0016] The second airflow section 5 has an inlet 51, an outlet 52, an airflow generating section 62, an applying section 63, and a first opening / closing section 64 (opening / closing section).

[0017] Air flows into the inlet 51 .

[0018] The outlet 52 allows the second airflow A2 to flow out and merge with the first airflow A1.

[0019] The airflow generating unit 62 is disposed in the flow path 6 between the inlet 51 and the outlet 52, and generates a second airflow A2.

[0020] The imparting unit 63 is disposed in the flow channel 6 and imparts the functional component to the air.

[0021] The opening / closing unit 64 is disposed in the flow channel 6 between the application unit 63 and the outlet 52 , and opens and closes the flow channel 6 .

[0022] According to the air blowing system 1 of the present embodiment, the opening / closing unit 64 is disposed between the imparting unit 63 and the outlet 52, and therefore, the opening / closing unit 64 opens and closes the flow path 6, thereby switching whether or not the functional component is imparted to the first airflow A1. Furthermore, when the opening / closing unit 64 closes the flow path 6, leakage of the functional component from the outlet 52 can be suppressed.

[0023] (2) Details Hereinafter, a detailed configuration of the air blowing system 1 according to the first embodiment will be described with reference to FIG.

[0024] (2.1) Overall structure The air blowing system 1 of this embodiment is installed on an installation surface 101 such as a ceiling or wall surface of a facility. In this embodiment, it is assumed that the facility is an office. Note that the "facility" referred to in this disclosure includes residential facilities used for residential purposes, as well as non-residential facilities such as stores, offices, welfare facilities, educational facilities, hospitals, and factories. Non-residential facilities also include restaurants, amusement parks, hotels, inns, kindergartens, nurseries, and community centers. In other words, the facility may be a residential facility such as an apartment building, or a non-residential facility such as an office. Furthermore, the facility may include a combination of residential and non-residential facilities, for example, with stores on the lower floors and residences on the upper floors.

[0025] The air blowing system 1 of this embodiment includes a base 2, an arm 3, a first airflow section 4, and a second airflow section 5.

[0026] The base 2 is attached to an installation surface 101. In this embodiment, the installation surface 101 is a ceiling surface. However, the base 2 may be attached to a wiring duct installed on the installation surface 101, or may be attached to a wiring duct suspended from the installation surface 101, such as a ceiling surface.

[0027] The base 2 of this embodiment also houses a control unit 9.

[0028] The arm 3 is formed in a rod shape. The arm 3 connects the base 2 and the first air current section 4. The arm 3 supports the first air current section 4 in a state in which the first air current section 4 can rotate around a rotation axis. The rotation axis is parallel to the direction perpendicular to the paper surface of FIG. 1.

[0029] (2.2) First airflow section The first airflow section 4 blows out a first airflow A1 that travels in a straight line. More specifically, the first airflow A1 generated by the first airflow section 4 is a jet, a directional airflow that travels in a straight line. Because the first airflow A1 does not easily diffuse, the air blowing system 1 of this embodiment can suppress the diffusion of the functional ingredients and efficiently transport the functional ingredients to the target area. The strength of the airflow blown out by the first airflow section 4 is controlled by the control section 9.

[0030] The first airflow section 4 has a main body 40. The main body 40 is formed in a cylindrical shape. The main body 40 is mechanically connected to the arm 3. In this embodiment, the main body 40 is mechanically connected to the arm 3 on the upper side of the main body 40. In addition, a housing 50 of the second airflow section 5, which will be described later, is provided below the main body 40 in this embodiment.

[0031] The upper side of the main body 40 refers to one end side (first end side) of the main body 40 in a direction perpendicular to the axial direction of the cylindrical main body 40. The lower side of the main body 40 refers to the other end side (second end side) of the main body 40 in a direction perpendicular to the axial direction of the cylindrical main body 40. In the present disclosure, the axial direction of the cylindrical main body 40 is referred to as the first direction, and the direction perpendicular to the axial direction of the main body 40 is referred to as the second direction. In the present disclosure, the direction perpendicular to the first and second directions is referred to as the third direction. The third direction is a direction perpendicular to the plane of the paper in FIG. 1.

[0032] The main body 40 has an inlet 41 and an outlet 42. The inlet 41 is formed at a first end (the right end in FIG. 1 ) of the main body 40 in the first direction, and the outlet 42 is formed at a second end (the left end in FIG. 1 ) of the main body 40 in the first direction. In the present disclosure, the first end of the main body 40 in the first direction is the rear end of the main body 40, and the second end of the main body 40 in the first direction is the front end of the main body 40. When the fan housed in the main body 40 is driven, the first airflow section 4 draws in air through the inlet 41 and blows the drawn air out from the outlet 42. The first airflow section 4 blows out a first airflow A1 along the first direction. In the present disclosure, the direction in which the first airflow A1 travels is the forward direction.

[0033] (2.3) Second airflow section The second airflow section 5 merges the second airflow A2, to which the functional component has been added, with the first airflow A1. Examples of the functional component include a deodorizing component, a fragrance component, a disinfecting component, a sterilizing component, a beauty component, and a medicinal component.

[0034] The second airflow section 5 includes a housing 50. The housing 50 is formed in a rectangular box shape (i.e., a hollow rectangular parallelepiped shape). As described above, the housing 50 of this embodiment is provided below the main body 40 of the first airflow section 4. The housing 50 may be formed integrally with the main body 40 of the first airflow section 4.

[0035] The housing 50 is formed with an inlet 51 and an outlet 52. The inlet 51 is formed at the rear end of the housing 50, and the outlet 52 is formed at the front end of the housing. The inlet 51 and the outlet 52 are through-holes that connect to an air flow path 6 provided inside the housing 50. The inlet 51 is a through-hole that takes in air from outside the housing 50 into the flow path 6. The outlet 52 is a through-hole that expels air in the flow path 6 to the outside of the housing 50. In other words, the air that flows into the flow path 6 from the inlet 51 flows out of the flow path 6 from the outlet 52.

[0036] A flow path 6 is provided inside the housing 50. The flow path 6 of this embodiment includes a second opening and closing unit 61, an airflow generating unit 62, a supplying unit 63, and a first opening and closing unit 64 (opening and closing unit). In other words, the second airflow unit 5 of this embodiment includes the second opening and closing unit 61, the airflow generating unit 62, the supplying unit 63, and the first opening and closing unit 64 (opening and closing unit).

[0037] The second opening / closing unit 61 opens and closes the flow path 6. The second opening / closing unit 61 in this embodiment is a check valve. The second opening / closing unit 61 passes air flowing in a direction from the inlet 51 to the outlet 52, but does not pass air flowing in a direction from the outlet 52 to the inlet 51. The second opening / closing unit 61 is disposed upstream of the applying unit 63 in the flow path 6. That is, the second opening / closing unit 61 is disposed between the inlet 51 and the applying unit 63. More specifically, the second opening / closing unit 61 in this embodiment is disposed between the inlet 51 and the airflow generating unit 62. This makes it possible to prevent the functional component from leaking from the inlet 51. Note that the second opening / closing unit 61 does not necessarily have to be a check valve, and the second opening / closing unit 61 may be a valve that opens and closes the flow path 6 under the control of the control unit 9.

[0038] The airflow generating unit 62 has a blower fan or an air pump. The airflow generating unit 62 generates a second airflow A2 by sending out the air in the flow path 6 in a direction toward the outlet 52. The airflow generating unit 62 in this embodiment is disposed between the inlet 51 and the supplying unit 63. However, the airflow generating unit 62 may also be disposed between the supplying unit 63 and the outlet 52. The airflow generating unit 62 is controlled by the control unit 9.

[0039] The imparting unit 63 imparts a functional component to the second airflow A2 (or the air in the flow path 6) in the flow path 6. As a result, the second airflow A2 flowing out from the outlet 52 becomes an airflow containing the functional component. The imparting unit 63 is disposed upstream of the first opening / closing unit 64 in the flow path 6. More specifically, the imparting unit 63 in this embodiment is disposed between the airflow generating unit 62 and the first opening / closing unit 64.

[0040] The application unit 63 of this embodiment generates a functional component. The application unit 63 generates, for example, a mist containing the functional component. The application unit 63 is configured to supply the functional component from a functional component material 7 (see FIGS. 3 and 4) that generates the functional component. The functional component material 7 that generates the functional component is, for example, a solution containing the functional component. The application unit 63 of this embodiment has a container 632 (see FIGS. 3 and 4) that is configured to hold the functional component material 7 that generates the functional component.

[0041] The application unit 63 includes, for example, an atomization unit that atomizes the solution containing the functional ingredient, and an energy supply device that provides energy to the solution to atomize it in the atomization unit. The energy supply device is, for example, an ultrasonic vibrator, but is not limited to this and may be, for example, a SAW (Surface Acoustic Wave) device. The application unit 63 in this embodiment is controlled by the control unit 9.

[0042] The first opening / closing unit 64 opens and closes the flow path 6. It is a valve that opens and closes the flow path 6 based on the control of the control unit 9. The first opening / closing unit 64 in this embodiment is arranged downstream of the imparting unit 63 in the flow path 6. In other words, the second opening / closing unit 61 is arranged between the imparting unit 63 and the outlet 52. The second opening / closing unit 61 in this embodiment is in an open state when the airflow generating unit 62 is operating, and is in a closed state when the airflow generating unit 62 is not operating. This makes it possible to prevent the functional ingredient from leaking from the outlet 52 when the second airflow unit 62 is not operating.

[0043] (2.4) Control Unit The control unit 9 is mainly composed of a computer system having one or more processors and one or more memories. In the control unit 9, the one or more processors execute a program recorded in the memory, thereby realizing the functions of the control unit 9. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be provided by being recorded on a non-transitory recording medium such as a memory card.

[0044] The control unit 9 of this embodiment controls the operation of the first airflow unit 4 and the second airflow unit 5 based on operation commands received from a management device or the like. For example, when the control unit 9 receives an operation command to start the operation of the first airflow unit 4, it controls the first airflow unit 4 to generate the first airflow A1. Furthermore, when the control unit 9 receives an operation command to stop the operation of the first airflow unit 4, it controls the first airflow unit 4 to stop the operation of the first airflow unit 4. Furthermore, when the control unit 9 receives an operation command to start the operation of the second airflow unit 5, it controls the second airflow unit 5 to generate the second airflow A2 to which the functional component has been added. More specifically, when the control unit 9 receives an operation command to start the operation of the second airflow unit 5, it operates the airflow generation unit 62 and the adding unit 63 and opens the first opening / closing unit 64 to generate the second airflow A2 to which the functional component has been added. Furthermore, when the control unit 9 receives an operation command to stop the operation of the first airflow unit 4 or an operation command to stop the operation of the second airflow unit 5, it controls the second airflow unit 5 to stop the operation of the second airflow unit 5. More specifically, when the control unit 9 receives an operation command to stop the operation of the first airflow unit 4 or an operation command to stop the operation of the second airflow unit 5, it stops the operation of the airflow generating unit 62 and the applying unit 63 and closes the first opening / closing unit 64.

[0045] (3) Variations Modifications of the above embodiment are listed below.

[0046] (3.1) Variation 1 The air blowing system 1 according to the first modification will be described with reference to FIGS. 2A and 2B.

[0047] The airflow generating unit 62 according to the first modification is a diaphragm pump.

[0048] The airflow generating unit 62 according to the first modification includes a main body 620, a diaphragm 621, a first check valve 624, and a second check valve 625.

[0049] The main body 620 is formed in a box shape. An inlet 622 is formed at the rear end (the right end in FIG. 2A ) of the main body 620, and an outlet 623 is formed at the front end (the left end in FIG. 2A ) of the main body 620. The inlet 622 is located upstream of the outlet 623 in the flow path 6.

[0050] The first check valve 624 is a check valve provided at the inlet 622. The second check valve 625 is a check valve provided at the outlet 623. The first check valve 624 and the second check valve 625 allow air flowing in the direction from the inlet 51 (see FIG. 1) to the outlet 52 (see FIG. 1) to pass through, but do not allow air flowing in the direction from the outlet 52 to the inlet 51 to pass through.

[0051] The diaphragm 621 is a flexible membrane. The diaphragm 621 is displaced based on the control of the control unit 9. As shown in FIG. 2B, during the suction process, the diaphragm 621 is displaced so as to increase the volume of the internal space SP1 of the main body 620. During the suction process, the pressure in the internal space SP1 decreases, and air flows into the internal space SP1 from outside the internal space SP1 through the inlet 622 and the outlet 623. During the suction process, the first check valve 624 is open, and air flows into the internal space SP1 from outside the internal space SP1 through the inlet 622. Meanwhile, during the suction process, the second check valve 625 is closed, and no air flows in or out through the outlet 623. During the suction process, the amount of air in the internal space SP1 increases as air flows into the internal space SP1 from outside the internal space SP1 through the inlet 622.

[0052] As shown in FIG. 2A, in the discharge process, the diaphragm 621 is displaced so as to reduce the volume of the internal space SP1 of the main body 620. In the discharge process, the pressure in the internal space SP1 increases, and air attempts to flow out from the internal space SP1 to the outside of the internal space SP1 through the inlet 622 and the outlet 623. In the discharge process, the first check valve 624 is closed, and no air flows in or out through the inlet 622. On the other hand, in the discharge process, the second check valve 625 is open, and air flows out from the internal space SP1 to the outside of the internal space SP1 through the outlet 623. In the discharge process, the amount of air in the internal space SP1 is reduced by the amount of air flowing out from the internal space SP1 to the outside of the internal space SP1 through the outlet 623.

[0053] As described above, the airflow generating unit 62 according to Modification 1 generates the second airflow A2 by performing the suction process and the discharge process and discharging air from the outlet 623. As described above, the first check valve 624 and the second check valve 625 of the airflow generating unit 62 according to Modification 1 allow air flowing in the direction from the inlet 51 to the outlet 52 to pass through, but do not allow air flowing in the direction from the outlet 52 to the inlet 51 to pass through. The first check valve 624 and the second check valve 625 are disposed upstream of the applying unit 63 in the flow path 6. That is, the first check valve 624 and the second check valve 625 are disposed between the inlet 51 and the applying unit 63. This prevents the functional component from leaking from the inlet 51. That is, the first check valve 624 and the second check valve 625 function as a second opening / closing unit of the flow path 6. In other words, the second airflow unit 5 according to Modification 1 has a second opening / closing unit that opens and closes the flow path 6. Therefore, in the second airflow section 5 according to the first modification, leakage of the functional component from the inlet 51 can be suppressed without providing the second opening / closing section 61 (see FIG. 1) in addition to the airflow generating section 62.

[0054] (3.2) Variation 2 The air blowing system 1 according to the second modification will be described with reference to FIG.

[0055] The application unit 63 according to the second modification includes a fixing unit 631 and a container 632.

[0056] The fixed part 631 is fixed to the housing 50 of the second airflow part 5. An inlet 633 and an outlet 634 are formed in the fixed part 631. The inlet 633 is located upstream of the outlet 634 in the flow path 6. However, when the container 632 is not attached (connected) to the fixed part 631, the application part 63 does not form part of the flow path 6.

[0057] The container 632 is configured to be able to hold the functional ingredient material 7. In the second modification, for example, the functional ingredient material 7 is solid or semi-solid. This reduces the risk of the functional ingredient material 7 leaking from the second air flow section 5 compared to when the functional ingredient material 7 is liquid. However, even in the second modification, the functional ingredient material 7 may be liquid.

[0058] The container 632 of the second modification example is configured to be detachable from the fixed part 631 fixed to the housing 50 of the second airflow section 5. In other words, the container 632 is configured to be detachable from the second airflow section 5. By attaching the container 632 to the fixed part 631, a flow path is formed between the inlet 633 and the outlet 634 of the fixed part 631, and the application part 63 forms a part of the flow path 6.

[0059] According to the air blowing system 1 of the second modification, the functional ingredient material 7 can be easily replenished.

[0060] (3.3) Variation 3 The air blowing system 1 according to the third modification will be described with reference to FIG.

[0061] The container 632 of the application unit 63 according to the third modification is configured to be able to hold the liquid functional ingredient material 7. The container 632 is also configured to be able to hold the functional ingredient material 7 so that the liquid surface 71 of the functional ingredient material is perpendicular to the vertical direction (the direction perpendicular to the installation surface 101 in FIG. 4).

[0062] The container 632 of the second modification has two bearings 81 (only one is shown in FIG. 4 ) and a shaft 82. The bearing 81 is a bearing through which the shaft 82 passes. The shaft 82 is an axis along the third direction, and is fixed to the housing 50 of the second airflow section 5.

[0063] The container 632 of the second modification is supported by the housing 50 so as to be rotatable about the axis 82 as the rotation axis Ax1. Therefore, even if the first air flow section 4 and the second air flow section 5 rotate about the rotation axis along the third direction, the container 632 holds the functional ingredient material 7 so that the liquid surface 71 of the functional ingredient material 7 is perpendicular to the vertical direction. This reduces the risk of the functional ingredient material 7, which is a liquid, leaking from the second air flow section 5.

[0064] Moreover, the second airflow section 5 according to the third modification further includes a collection section 65 capable of collecting the functional ingredient material 7. The collection section 65 is formed of, for example, nonwoven fabric, diatomaceous earth, or sponge. In the third modification, the collection section 65 is provided on the edge of the outlet 52. This further reduces the risk of the functional ingredient material 7 leaking out of the second airflow section 5.

[0065] In addition, the container 632 of the third modification may be configured to have another structure such as a gimbal structure, so as to hold the functional ingredient material 7 so that the liquid surface 71 of the functional ingredient material 7 is perpendicular to the vertical direction.

[0066] Although FIG. 4 illustrates an example in which the applying unit 63 is located upstream of the airflow generating unit 62, the applying unit 63 may be located downstream of the airflow generating unit 62.

[0067] (3.4) Other variations In the above embodiment, the case where the control unit 9 is housed in the base 2 has been exemplified, but it is not essential that the control unit 9 be housed in the base 2. The control unit 9 may be housed in the first airflow unit 4 or the second airflow unit 5, etc., or may be provided on the installation surface 101, etc., separately from other components such as the first airflow unit 4 and the second airflow unit 5.

[0068] The second airflow section 5 may include a plurality of imparting sections 63 that impart different functional components to the second airflow A2. In this case, the air blowing system 1 can change the functional component imparted to the second airflow A2 by controlling the imparting sections 63 with the control section 9.

[0069] In the above embodiment, the second airflow section 5 merges the second airflow A2 with the first airflow A1 by sending the second airflow A2 forward of the outlet 42 of the first airflow section 4. However, the second airflow section 5 may merge the second airflow A2 with the first airflow A1 by sending the second airflow A2 rearward of the inlet 41 of the first airflow section 4. For example, the second airflow section 5 may be provided in the first airflow section 4 so as to be reversed left and right in FIG. 1 , thereby merging the second airflow A2 with the first airflow A1.

[0070] In the above embodiment, the second airflow section 5 merges the second airflow A2 with the first airflow A1 by sending the second airflow A2 forward of the outlet 42 of the first airflow section 4. However, the second airflow section 5 may merge the second airflow A2 with the first airflow A1 by sending the second airflow A2 to the flow path of the first airflow A1 within the first airflow section 4. For example, the outlet 52 of the second airflow section 5 may be connected to the flow path of the first airflow A1 within the first airflow section 4.

[0071] The functional ingredient may be charged atomized water particles containing OH radicals. In this case, the functional ingredient generating chamber may be, for example, an electrostatic atomizer that generates charged atomized water particles containing OH radicals. The charged atomized water particles are nanometer-sized atomized ions. For example, an electrostatic atomizer can generate atomized ions with particle diameters of 5 nm to 20 nm by applying a high voltage to water in the air. In the charged atomized water particles, the OH radicals easily react with various substances.

[0072] (summary) As is clear from the above-described embodiment and modified examples, the air blowing system (1) according to the first aspect includes a first airflow section (4) and a second airflow section (5). The first airflow section (4) generates a first airflow (A1). The second airflow section (5) merges a second airflow (A2) to which a functional component has been added into the first airflow (A1). The second airflow section (5) has an inlet (51), an outlet (52), an airflow generating section (62), an adding section (63), and an opening / closing section (first opening / closing section 64). Air flows in through the inlet (51). The outlet (52) discharges the second airflow (A2) and merges the second airflow (A2) into the first airflow (A1).
