[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference characters and the description will not be repeated. In the embodiment of the present invention, the X-axis, the Y-axis, and the Z-axis are mutually perpendicular, the X-axis and the Y-axis are parallel to the horizontal plane, and the Z-axis is parallel to the vertical line.

[0013] An ozone supplying device 1 according to an embodiment of the present invention will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a perspective view showing the ozone supplying device 1 according to the embodiment. Fig. 2 is a cross-sectional view showing the ozone supplying device 1 according to the embodiment. As shown in Figs. 1 and 2, the ozone supplying device 1 releases ozone (O3). Specifically, the ozone supplying device 1 releases ozone into a room (e.g., a store). The inside of the room is an example of a "predetermined area".

[0014] The room has a ceiling 111, multiple walls, a floor, and a duct rail R. The ceiling 111 is an example of a "mounting surface." The ceiling 111 may be a horizontal surface or an inclined surface. The mounting surface is different from the floor. The duct rail R is an example of a "rail member." At least one of the multiple walls is provided with a door. People (e.g., customers or store clerks) enter and exit the room by opening and closing the door.

[0015] The duct rail R is attached to the ceiling 111. The duct rail R may be embedded in the ceiling 111, or may be suspended from the ceiling 111 by an arm, a wire, or the like. The duct rail R may also be fixed to a wall.

[0016] The duct rail R is long. The duct rail R extends along a first direction PD1. The first direction PD1 extends along the ceiling 111. The first direction PD1 is the X direction. Specifically, the duct rail R includes an insertion port portion R3, a pair of conductor portions R1, and a pair of recesses R2. The insertion port portion R3, the pair of conductor portions R1, and the pair of recesses R2 each extend along the longitudinal direction of the duct rail R (the first direction PD1).

[0017] The insertion opening R3 is open in the direction opposite to the second direction PD2. The second direction PD2 is perpendicular to the first direction PD1. Specifically, the second direction PD2 is the Z direction.

[0018] The pair of conductor portions R1 face each other in a third direction PD3 with the insertion opening portion R3 in between. The third direction PD3 is perpendicular to the first direction PD1 and perpendicular to the second direction PD2. The third direction PD3 is the Y direction. Each of the pair of conductor portions R1 is made of metal. An external power supply voltage (e.g., AC (alternating current) 100V) is applied to the pair of conductor portions R1.

[0019] The pair of recesses R2 face each other in the third direction PD3 across the insertion opening R3. The pair of recesses R2 are provided on the opposite side in the second direction PD2 from the pair of conductor portions R1.

[0020] The ozone supplying device 1 according to this embodiment is attached to a duct rail R. Specifically, the ozone supplying device 1 includes an ozone generating unit 10 and a plug unit 20. The plug unit 20 is an example of a "connecting unit." Note that a device other than the ozone supplying device 1 may be attached to the duct rail R. The device other than the ozone supplying device 1 is, for example, a lighting device. Also, a plurality of ozone supplying devices 1 may be attached to the duct rail R.

[0021] The plug portion 20 has a post portion 23, a pair of projections 21, and a pair of terminal portions 22. The post portion 23 extends along the second direction PD2. For example, the post portion 23 is a substantially cylindrical member.

[0022] The pair of protruding portions 21 face each other in the third direction PD3 with the support portion 23 therebetween. Each of the pair of protruding portions 21 is a plate-shaped member extending along the third direction PD3.

[0023] The pair of terminal portions 22 face each other in the third direction PD3. Each of the pair of terminal portions 22 includes a plate-like member extending along the third direction PD3 and a plate-like member extending along the second direction PD2. Each of the pair of terminal portions 22 is made of metal. Each of the lower ends of the pair of terminal portions 22 is connected to a power connector of the ozone generation unit 10 via an electric wire (not shown). In other words, the plug portion 20 supplies power from the duct rail R to the ozone generation unit 10.

[0024] The plug portion 20 can be connected to the duct rail R. Specifically, the plug portion 20 is connected to the duct rail R. More specifically, the support portion 23 is inserted into the insertion port portion R3. The pair of protrusions 21 are connected to the pair of recesses R2. The pair of terminal portions 22 are connected to the pair of conductor portions R1. More specifically, the plug portion 20 can switch the connection state. The connection state includes a first state and a second state. The first state indicates a state in which the recesses R2 and the protrusions 21 are not connected, and the conductor portions R1 and the terminal portions 22 are not connected. The second state indicates a state in which the recesses R2 and the protrusions 21 are connected, and the conductor portions R1 and the terminal portions 22 are connected. The first state indicates a state in which the protrusions 21 and the terminal portions 22 can move along the second direction PD2 within the insertion port portion R3. In other words, the plug portion 20 is detachably attached to the duct rail R. An example of a method for attaching and detaching the plug portion 20 will be described later with reference to Figs.

[0025] Next, the ozone supplying device 1 according to the present embodiment will be described in detail with reference to Fig. 3. Fig. 3 is an exploded perspective view of the ozone supplying device 1. As shown in Fig. 3, the ozone supplying device 1 may further include an engagement portion 30. The engagement portion 30 and the plug portion 20 face each other in the first direction PD1.

[0026] The engagement portion 30 has a support portion 33 and a pair of protrusions 31. The support portion 33 extends along the second direction PD2. For example, the support portion 33 is a substantially cylindrical member.

[0027] The pair of protruding portions 31 face each other in the third direction PD3 with the support portion 33 therebetween. Each of the pair of protruding portions 31 is a plate-shaped member extending along the third direction PD3.

[0028] The engaging portion 30 can engage with the duct rail R. Specifically, the engaging portion 30 is engaged with the duct rail R. More specifically, the support portion 33 is inserted into the insertion port portion R3. The pair of protrusions 31 are connected to the pair of recesses R2. More specifically, the engaging portion 30 can switch the connection state. The connection state includes a third state and a fourth state. The third state indicates a state in which the duct rail R and the protrusion 31 are not connected. The fourth state indicates a state in which the duct rail R and the protrusion 31 are connected. In addition, the third state indicates a state in which the protrusion 31 can move along the second direction PD2 within the insertion port portion R3. In other words, the engaging portion 30 is detachably attached to the duct rail R. In addition, the engaging portion 30 may have a pair of terminal portions, similar to the plug portion 20.

[0029] The ozone generating unit 10 generates ozone. Ozone has a sterilizing effect and a deodorizing effect. In this specification, sterilization means, for example, reducing bacteria, mold, viruses, etc. The action of ozone may include an antibacterial effect of suppressing the growth and proliferation of bacteria, mold, viruses, etc. The concept of deodorization also includes the decomposition of odorous substances such as hydrogen sulfide (H2S) and ammonia (NH3).

[0030] For example, when ozone is released into the air, it surrounds the surface of bacteria or viruses present in the room. Ozone can inactivate bacteria or viruses and reduce their vital activity. Since ozone is an active species with extremely high oxidizing power, it can affect not only bacteria and viruses but also humans when the ozone concentration in the air exceeds a certain concentration (e.g., 0.1 ppm).

[0031] Specifically, the ozone generating unit 10 includes an ultraviolet lamp and an inverter. For example, the ultraviolet lamp is a low pressure mercury lamp (low pressure mercury lamp), a xenon lamp (xenon lamp), an excimer lamp, a deuterium lamp, or the like. The ultraviolet lamp emits ultraviolet light when a voltage is applied. Specifically, the external power supply voltage from the plug unit 20 is converted by a converter (power supply unit) and an inverter, or the like, and the ultraviolet lamp emits ultraviolet light. The ultraviolet light preferably includes light having a central wavelength of 1 nm or more and 400 nm or less, for example.

[0032] For example, the ozone generator 10 generates a set amount of ozone (O3) from oxygen molecules (O2) by irradiating them with light having a central wavelength of 150 nm or more and 200 nm or less. As a result, it is possible to suppress the generation of by-products (nitric oxide (NO) or nitrogen dioxide (NO2)). In addition, since it is a generation device that uses ultraviolet light irradiation, it can maintain the generation of the set amount of ozone even after a long period of time, compared to a generation device that uses a discharge method.

[0033] As described above with reference to Figs. 1 to 3, the ozone supplying device 1 includes the ozone generating unit 10 and the plug unit 20. The plug unit 20 supplies power from the duct rail R to the ozone generating unit 10. As a result, the ozone generating unit 10 can be driven. Therefore, the ozone generating unit 10 can be placed in a location different from the floor. As a result, the ozone generating unit 10 can release ozone from a location different from the floor. Therefore, the ozone can be efficiently released into the room.

[0034] Specifically, since the specific gravity of ozone (O3) is heavier than the specific gravity of oxygen molecules (O2), nitrogen molecules (N2), and carbon dioxide (CO2), ozone falls through the air from the ceiling 111. As a result, the ozone supplying device 1 can efficiently diffuse ozone in the room. In other words, the ozone supplying device 1 can diffuse ozone over a wide range in the room.

[0035] In addition, since the ozone supplying device 1 can be placed in a place different from the floor, the ozone supplying device 1 is not visible to people (for example, customers), and thus influence on the aesthetic appearance of a room (for example, a store) can be suppressed.

[0036] Furthermore, since the ozone supplying device 1 includes the plug portion 20, the ozone supplying device 1 can be easily disposed in a location different from the floor. Also, the ozone supplying device 1 can be easily disposed in any position in the duct rail R.

[0037] 2 to 4, the housing 40 in which the ozone generation unit 10 is housed will be described in detail. Fig. 4 is another exploded perspective view of the ozone supplying device 1. As shown in Figs. 2 to 4, the ozone supplying device 1 further includes the housing 40 and a sending unit 50.

[0038] The shape of the housing 40 is, for example, a rectangular parallelepiped. Specifically, the housing 40 has a top plate 42, a bottom plate 43, and a plurality of side walls 41. The plurality of side walls 41 include a right side wall 41a, a left side wall 41b, a front side wall 41c, and a rear side wall 41d. The front side wall 41c and the rear side wall 41d face each other in the first direction PD1. The right side wall 41a and the left side wall 41b face each other in the third direction PD3. The housing 40 is made of, for example, a synthetic resin.

[0039] The housing 40 further has a pair of intake ports 44 and an exhaust port 45. The pair of intake ports 44 are preferably disposed on the right side wall 41a and the left side wall 41b. Each of the pair of intake ports 44 is, for example, a collection of a plurality of openings. Each of the plurality of openings is, for example, circular.

[0040] The discharge port 45 is preferably disposed approximately in the center of the lower plate 43. The discharge port 45 is, for example, a single opening. The opening is, for example, circular.

[0041] The ozone generating unit 10 is disposed within a housing 40. The sending unit 50 is also disposed within the housing 40.

[0042] Specifically, the sending unit 50 has a fan 51 and a fan motor 52. The fan motor 52 drives the fan 51. A power connector of the fan motor 52 is connected to a pair of terminal units 22 via electric wires (not shown). In particular, an external power supply voltage is applied to the fan motor 52, and the fan motor 52 drives the fan 51 at a predetermined rotation speed.

[0043] The fan 51 is, for example, an axial flow type fan. The axial flow type fan has a plurality of blades and a rotating shaft. The plurality of blades are located along the outer periphery of the rotating shaft. Specifically, the plurality of blades are arranged radially from the rotating shaft. More specifically, the fan 51 has a rotation axis BX extending along the second direction PD2. When the fan 51 is driven, the air sucked in from the second direction PD2 side of the fan 51 is blown out in the opposite direction of the second direction PD2 of the fan 51.

[0044] The delivery section 50 is disposed in the second direction PD2 from the discharge port 45. Specifically, the fan 51 faces the discharge port 45.

[0045] As described above with reference to FIG. 1 to FIG. 4, the ozone generating unit 10 and the sending unit 50 are disposed in the housing 40. The sending unit 50 releases ozone from the outlet 45 to the outside of the housing 40. As a result, ozone can be more efficiently released from the outlet 45 toward a predetermined area. In addition, since the ozone generating unit 10 can be accommodated in the housing 40, even if the ozone supplying device 1 is seen by a person (e.g., a customer), the impact on the aesthetics of the room (e.g., a store) can be suppressed. Furthermore, by designing the housing 40 based on straight lines and flat surfaces as in this embodiment, a sense of unity in appearance with the ceiling and the duct rail is created, making it less noticeable, and the impact on the aesthetics of the room (e.g., a store) can be suppressed. Note that the shape of the housing 40 in this embodiment is one example, and other shapes can be used as long as it can accommodate the ozone generating unit 10 and release ozone.

[0046] Next, a detailed description will be given of the control unit 70 that controls the driving of the ozone generation unit 10. As shown in FIG.

[0047] The power supply unit 60 generates an internal power supply voltage (DC (Direct Current)) based on the external power supply voltage (AC 100V) from the plug unit 20, and applies the internal power supply voltage to the ozone generation unit 10. Specifically, the power supply unit 60 includes an AC-DC power supply unit (converter).

[0048] In detail, the ozone supplying device 1 includes a plurality of power supply units 60. The plurality of power supply units 60 include a first power supply unit 61 and a second power supply unit 62. The first power supply unit 61 generates an internal power supply voltage (DC) based on an external power supply voltage (AC 100V) from the plug unit 20, and applies the internal power supply voltage to the ozone generating unit 10 and the sending unit 50. The second power supply unit 62 generates an internal power supply voltage (DC) based on the external power supply voltage (AC 100V) from the plug unit 20, and applies the internal power supply voltage to the control unit 70.

[0049] The control unit 70 controls the ozone generation unit 10 and the sending unit 50. The control unit 70 is connected to the second power supply unit 62 via an electric wire (not shown). In detail, the control unit 70 is constantly applied with an internal power supply voltage (DC) and controls the ozone generation unit 10 and the sending unit 50.

[0050] Specifically, the control unit 70 includes a hardware circuit including a processor such as a CPU (Central Processing Unit). In more detail, the control unit 70 switches the ozone generation unit 10 and the sending unit 50 between on and off. On, for example, means turning on the power. Off, for example, means turning off the power. In more detail, the control unit 70 switches the first power supply unit 61 between on and off.

[0051] The housing 40 preferably further includes a first flow passage G1, a second flow passage G2, and a partition plate G3. Specifically, the partition plate G3 is disposed between the first flow passage G1 and the second flow passage G2. The first flow passage G1 extends from a part of the intake port 44 on the left side wall to the exhaust port 45. The second flow passage G2 is a portion of the housing 40 other than the first flow passage G1.

[0052] The ozone generation unit 10 and the delivery unit 50 are disposed in the first flow passage G1. In detail, the ozone generation unit 10 is disposed in the third direction PD3 from the delivery unit 50.

[0053] The power supply unit 60 is preferably disposed below the plug unit 20 or the engagement unit 30. Specifically, the first power supply unit 61 and the second power supply unit 62 are disposed below the engagement unit 30. In addition, the control unit 70 is disposed below the plug unit 20. As a result, the ozone supplying device 1 can be stably disposed on the duct rail R.

[0054] In detail, the first power supply unit 61, the second power supply unit 62, and the control unit 70 are disposed in the second flow passage G2. Specifically, the first power supply unit 61 and the second power supply unit 62 are disposed in the first direction PD1 from the first flow passage G1. Also, the control unit 70 is disposed in the opposite direction to the first direction PD1 from the first flow passage G1. As a result, the ozone supplying device 1 can be disposed on the duct rail R more stably.

[0055] 2 and 5, the flow of air blown out from the ozone supplying device 1 will be described. FIG. 5 is a cross-sectional view showing an example of the ozone supplying device 1. The first airflow F1, the second airflow F2, and the third airflow F3 each represent an air flow. The first airflow F1 represents an air flow sucked into the first flow passage G1. The second airflow F2 represents an air flow sucked into the second flow passage G2. The third airflow F3 represents an air flow blown out from the housing 40.

[0056] 2 and 5, the ozone supplying device 1 further includes a lower plate 49. The lower plate 49 is a plate-shaped member. The lower plate 49 is disposed in the opposite direction of the second direction PD2 from the outlet 45. As a result, ozone spreads over a wide area of ​​the room.

[0057] The fan 51 rotates when the fan motor 52 is driven. The fan 51 draws air from the intake port 44 into the first flow passage G1. The air drawn into the first flow passage G1 flows along the first airflow F1. In other words, the first airflow F1 flows along the ozone generating unit 10. As a result, the air contains ozone. In addition, bacteria or viruses present in the air can be inactivated.

[0058] The air containing ozone is sucked into the fan 51. The air sucked into the fan 51 is discharged to the outside of the housing 40 from the outlet 45. The air discharged from the outlet 45 is blown out along the third airflow F3 by the lower plate 49. In other words, ozone is discharged to the outside of the housing 40 from the outlet 45.

[0059] Also, the fan 51 draws air from the intake port 44 into the second flow passage G2. The air drawn into the second flow passage G2 flows along the second airflow F2. In other words, the second airflow F2 flows along the first power supply unit 61, the second power supply unit 62, and the control unit 70. As a result, the first power supply unit 61, the second power supply unit 62, and the control unit 70 are cooled. The air that has cooled the first power supply unit 61, the second power supply unit 62, and the control unit 70 passes through the gap G3a provided between the partition plate G3 and the left side wall 41b, and is drawn into the first flow passage G1. The air drawn into the first flow passage G1 is drawn into the fan 51. The air drawn into the fan 51 is discharged from the discharge port 45 to the outside of the housing 40. The air discharged from the discharge port 45 is blown out by the lower plate 49 along the third airflow F3.

[0060] 4 and 6, the flow of power in the ozone supplying device 1 will be described. Fig. 6 is a configuration diagram showing a circuit of the ozone supplying device 1. As shown in Figs. 4 and 6, the ozone supplying device 1 further includes a human sensor 81, a first lamp 83, and a second lamp 82.

[0061] The human sensor 81, the first lamp 83, and the second lamp 82 are disposed on the lower plate 43. In detail, the human sensor 81, the first lamp 83, and the second lamp 82 are disposed in through holes of the lower plate 49.

[0062] The human presence sensor 81 detects whether or not a person is present. Specifically, the human presence sensor 81 detects whether or not a person is present in a room. The human presence sensor 81 is, for example, an infrared sensor or a carbon dioxide sensitivity sensor. The human presence sensor 81 may also be, for example, an illuminance sensor that indicates the brightness of the room. The human presence sensor 81 is connected to the control unit 70 via an electric wire. In detail, the human presence sensor 81 is applied with an internal power supply voltage (DC) from the control unit 70, detects whether or not a person is present in the room, and outputs the detection result to the control unit 70.

[0063] The control unit 70 switches the first power supply unit 61 on and off based on the detection result. Specifically, when the detection result indicates that a person is present, the control unit 70 turns off the first power supply unit 61. In other words, when a person is present, ozone is not released into the room. On the other hand, when the detection result indicates that a person is not present, the control unit 70 turns on the first power supply unit 61. In other words, when a person is not present, ozone is released into the room. As a result, it is possible to suppress the effects on people.

[0064] The first lamp 83 is an ozone generation indicator lamp, and emits visible light. Specifically, the first lamp 83 emits blue light. The first lamp 83 is connected to the first power supply unit 61 via an electric wire. As a result, when the control unit 70 turns on the first power supply unit 61, the first lamp 83 emits visible light. On the other hand, when the control unit 70 turns off the first power supply unit 61, the first lamp 83 does not emit visible light. Therefore, a person can recognize that the ozone generation unit 10 is operating.

[0065] The second lamp 82 is a human sensor operation indicator lamp and emits visible light. Specifically, the first lamp 83 emits green light. The second lamp 82 is connected to the control unit 70 via an electric wire.

[0066] The control unit 70 controls the second lamp 82. Specifically, when the detection result indicates that a person is present, the control unit 70 blinks the second lamp 82. On the other hand, when the detection result indicates that a person is not present, the control unit 70 turns on the second lamp 82. As a result, a person can recognize that the human sensor 81 is activated.

[0067] Next, an example of the antibacterial method according to the present embodiment will be described with reference to Fig. 7. Fig. 7 is a flowchart showing the antibacterial method according to the present embodiment. As shown in Fig. 7, the antibacterial method includes steps S101 to S111. The antibacterial method is performed by the ozone supplying device 1.

[0068] First, in step S101, the control unit 70 controls the second lamp 82 so that the second lamp 82 is turned on.

[0069] Next, in step S102, the control unit 70 determines whether or not a person is present in the room based on the detection result of the human presence sensor 81. If the control unit 70 determines that no person is present in the room (NO in step S102), the process returns to step S101. On the other hand, if the control unit 70 determines that a person is present in the room (YES in step S102), the process proceeds to step S103.

[0070] Next, in step S103, the control unit 70 controls the second lamp 82 so that the second lamp 82 blinks.

[0071] Next, in step S104, the control unit 70 determines whether or not a person is present in the room based on the detection result of the human presence sensor 81. If the control unit 70 determines that a person is present in the room (YES in step S104), the process returns to step S103. On the other hand, if the control unit 70 determines that a person is present in the room (NO in step S104), the process proceeds to step S105.

[0072] Next, in step S105, the control unit 70 controls the second lamp 82 so that the second lamp 82 is turned on.

[0073] Next, in step S106, the control unit 70 determines whether or not 10 seconds have elapsed. If the control unit 70 determines that 10 seconds have not elapsed (NO in step S106), the process returns to step S104. On the other hand, if the control unit 70 determines that 10 seconds have elapsed (YES in step S106), the process proceeds to step S107. Note that the reference time in step S106 is not limited to 10 seconds, and may be another time (for example, 1 minute).

[0074] Next, in step S107, the control unit 70 turns on the first power supply unit 61 so that the ozone generation unit 10, the fan 51, and the first lamp 83 are driven.

[0075] Next, in step S108, the control unit 70 determines whether or not a person is present in the room based on the detection result of the human presence sensor 81. When the control unit 70 determines that a person is present in the room (YES in step S108), the process proceeds to step S109.

[0076] Next, in step S109, the control unit 70 turns off the first power supply unit 61 so as not to drive the ozone generation unit 10, the fan 51, and the first lamp 83. After that, the process returns to step S103.

[0077] On the other hand, if the control unit 70 determines that a person is present in the room (NO in step S108), the process proceeds to step S110. Next, in step S110, the control unit 70 determines whether or not one minute has passed. In this embodiment, it is one minute, but it may be adjusted automatically or manually depending on the ozone concentration in the room. If the control unit 70 determines that one minute has not passed (NO in step S110), the process returns to step S107. On the other hand, if the control unit 70 determines that one minute has passed (YES in step S110), the process proceeds to step S111. Note that the reference time in step S110 is not limited to one minute, and may be another time (for example, one hour or more).

[0078] Next, in step S111, the control unit 70 turns off the first power supply unit 61 so as not to drive the ozone generation unit 10, the fan 51, and the first lamp 83. After that, the process returns to step S101.

[0079] Here, the plug portion 20 will be described in more detail with reference to Fig. 8 and Fig. 9. Fig. 8 is an enlarged perspective view of the plug portion 20. Fig. 9 is another enlarged perspective view of the plug portion 20. As shown in Figs. 8 and 9, the plug portion 20 further includes a switching portion 130.

[0080] The switching unit 130 switches the connection state of the plug unit 20 with respect to the duct rail R.

[0081] Specifically, the switching unit 130 includes a lever. The switching unit 130 is attached to the plug unit 20. The switching unit 130 is rotatable about 90° around the rotation axis AX. In other words, the plug unit 20 is rotatable about 90° around the rotation axis AX. More specifically, the switching unit 130 and the plug unit 20 rotate in a first rotation direction RA around the rotation axis AX. The first rotation direction RA indicates the rotation direction when the plug unit 20 changes from the first state to the second state. In addition, the switching unit 130 and the plug unit 20 rotate in a second rotation direction RB around the rotation axis AX. The second rotation direction RB indicates the rotation direction when the plug unit 20 changes from the second state to the first state.

[0082] Furthermore, the plug portion 20 is disposed in a recess 48 of the housing 40. When the connection state of the plug portion 20 is in the first state, the switching portion 130 protrudes from the recess 48 as shown in Fig. 8. When the connection state of the plug portion 20 is in the second state, the switching portion 130 is accommodated in the recess 48 as shown in Fig. 9.

[0083] As a result, the switching unit 130 can be operated even when the ozone supplying device 1 is attached to the duct rail R. This improves convenience when operating the switching unit 130. In addition, when the ozone supplying device 1 is attached to the duct rail R, the switching unit 130 is housed in the recess 48, improving the aesthetic appearance of the ozone supplying device 1.
