(Embodiment 1)
First, a ceiling fan 100 according to Embodiment 1 of the present invention will be described with reference to FIG. FIG. 1 is a side view showing a ceiling fan 100. FIG. As shown in FIG. 1, the ceiling fan 100 of Embodiment 1 can be attached to the ceiling surface C, for example. In addition, the ceiling surface C may be parallel to the horizontal direction, or may be inclined with respect to the horizontal direction. Also, the ceiling fan 100 may be attached to the ceiling surface C via a duct rail. In this case, the ceiling fan 100 is attached to a duct rail, and the duct rail may be directly attached (fixed) to the ceiling surface C, embedded in the ceiling surface C, or attached to an arm or wire. It may be suspended from the ceiling surface C by, for example. Ceiling fan 100 is an example of a "hazard control device."

In Embodiment 1, the ceiling fan 100 includes a harmful substance control section 1 , a blower section 2 , a mounting section 3 and a connecting section 4 .

The mounting portion 3 can be mounted on the ceiling surface C. As shown in FIG. In the example shown in FIG. 1, the mounting portion 3 is mounted on the ceiling surface C. As shown in FIG. Mounting unit 3 includes housing 30 .

The blower 2 generates an airflow. The air blower 2 includes a housing 20 and blades 21 . The housing 20 has a facing surface 26 that faces the mounting portion 3 . Specifically, the facing surface 26 faces the mounting portion 3 in the direction in which the connecting portion 4 extends. The facing surface 26 has an opening h1.

The air blower 2 rotates the blades 21 around the rotation axis AX to generate an airflow F1 toward the ceiling surface C or an airflow F2 toward the ceiling surface C away from the ceiling surface C. The rotation axis AX is the central axis of the blower section 2 . Further, the rotation axis AX is the central axis of the connecting portion 4 .

The connecting portion 4 connects the mounting portion 3 and the blower portion 2 . In this embodiment, the connecting portion 4 has an elongated cylindrical shape. Wiring (not shown) that connects, for example, an external power source, the air blower 2 and the light source 1B is inserted through the interior of the connecting portion 4 . The external power supply is a commercial power supply. In a state in which the ceiling fan 100 is attached to the ceiling surface C, the connecting portion 4 extends, for example, along the vertical direction (Z direction). The light source section 1B will be described later.

The harmful substance control unit 1 controls harmful substances. Hereinafter, the hazardous substances may be referred to as "hazardous substances SA". Harmful substances SA are, for example, those that make people feel uncomfortable. Harmful substances SA are, for example, bacteria, viruses, smoke, perfumes (residual odors), or pests. Smoke is an example of inorganic or organic matter. Perfume is an example of an organic substance. Controlling the pollutant SA means acting on the pollutant SA. An example of controlling the harmful substances SA will now be described.

Specifically, controlling the harmful substances SA includes, for example, killing, suppressing growth of, removing, or decomposing the harmful substances SA. More specifically, for example, when the harmful substance SA is a virus, the harmful substance control unit 1 kills the virus, suppresses the growth of the virus, or removes the virus. Further, for example, when the harmful substance SA is a bacterium, the harmful substance control unit 1 kills the bacterium, reduces the bacterium, desensitizes the bacterium, neutralizes the toxicity of the bacterium, and suppresses the growth of the bacterium. , or remove bacteria. Further, for example, when the harmful substance SA is smoke, the harmful substance control unit 1 decomposes or removes the smoke. Then, for example, when the harmful substance SA is perfume, the harmful substance control unit 1 decomposes or removes the perfume. Further, for example, if the harmful substance SA is a pest, the harmful substance control unit 1 kills or removes the pest. The harmful substance control unit 1 controls the harmful substance SA by, for example, emitting electromagnetic waves or gas toward the harmful substance SA.

In Embodiment 1, the hazardous substance control unit 1 includes an ozone generator 1A. 1 A of ozone generators are arrange|positioned at the mounting part 3, for example. Specifically, the ozone generator 1A is arranged inside the housing 30 of the mounting portion 3 . That is, in Embodiment 1, the housing 30 accommodates the ozone generator 1A.

The ozone generator 1A generates ozone. Ozone is an example of a gas. The ozone generator 1A emits ozone toward a predetermined area. Therefore, the ozone generator 1A can control the harmful substances SA in the air by releasing ozone into the air. Specifically, the ozone generator 1A emits ozone into the air to kill the harmful substances SA in the air, suppress the growth of the harmful substances SA in the air, and remove the harmful substances SA in the air. or decompose harmful substances SA in the air.

Ozone falls through the air because its specific gravity is higher than that of other molecules in the air (eg, oxygen molecules, nitrogen molecules, and carbon dioxide). Therefore, by arranging the ozone generator 1A at a position close to the ceiling surface C, ozone can be efficiently diffused. For example, by arranging the ozone generator 1A in the mounting portion 3 as in the first embodiment, ozone can be efficiently diffused indoors.

Moreover, in Embodiment 1, the harmful substance control unit 1 includes the light source unit 1B. The light source unit 1B is arranged in the blower unit 2, for example. Specifically, the light source unit 1B is arranged inside the blower unit 2 . That is, in Embodiment 1, the housing 20 accommodates the light source section 1B.

The light source unit 1B emits light. The light emitted from the light source unit 1B is emitted to the outside of the housing 20 through the opening h1 of the facing surface 26. As shown in FIG. In Embodiment 1, the light source 14 (see FIG. 2) of the light source unit 1B emits ultraviolet rays UV. That is, in Embodiment 1, the light source 14 is, for example, an ultraviolet lamp. The ultraviolet lamp is, for example, a low-pressure mercury lamp (low-pressure mercury lamp), a xenon lamp (xenon lamp), an excimer lamp, a deuterium lamp, or the like. Therefore, the predetermined area irradiated with the ultraviolet rays UV can be sterilized. Ultraviolet rays UV include, for example, light with a wavelength of 1 nm or more and 400 nm or less, and preferably light with a center wavelength of 150 nm or more and 230 nm or less. Among them, the light of 222 nm has little effect on the human body and has a sterilizing effect, so it is more preferable that the light source unit 1B of Embodiment 1 emit ultraviolet light having a central wavelength of approximately 222 nm, for example.

Therefore, the light source unit 1B can control the harmful substances SA in the air by emitting ultraviolet light into the air. Specifically, the light source unit 1B emits ultraviolet light into the air to kill the harmful substances SA in the air, suppress the growth of the harmful substances SA in the air, and remove the harmful substances SA in the air. or decompose harmful substances SA in the air.

Further, in Embodiment 1, the ultraviolet rays UV are emitted toward the ceiling surface C through the facing surface 26 . Therefore, it is possible to more effectively suppress the irradiation of the ultraviolet rays UV to the user present in the room.

In this embodiment, the ozone generator 1A is arranged in the mounting section 3, and the light source section 1B is arranged in the blower section 2. As shown in FIG. Therefore, each of the mounting portion 3 and the air blowing portion 2 can be miniaturized. As a result, the appearance of the ceiling fan 100 can be improved.

Hereinafter, for convenience of explanation, the side on which the blowing unit 2 is arranged with respect to the mounting unit 3 is defined as the “lower side,” and the side on which the mounting unit 3 is arranged with respect to the blowing unit 2 is defined as the “upper side. ” to define the vertical direction.

As shown in FIG. 2 , blower section 2 further includes power supply section 22 and motor 23 . The power supply unit 22 is connected to an external power supply. External power is supplied to the power supply unit 22 . The power supply unit 22 converts external power into internal power and supplies the internal power to the motor 23 . The internal power causes the motor 23 to rotate the vanes 21 . The motor 23 is an example of a "driving unit".

The ozone generator 1A includes a power supply section 11 and an ozone generation section 12 . The power supply unit 11 is connected to an external power supply and supplied with external power. The power supply unit 11 converts external power into internal power and supplies the internal power to the ozone generating unit 12 . The ozone generator 12 generates ozone by internal electric power.

Light source unit 1B further includes power supply unit 13 . The power supply unit 13 is connected to an external power supply and supplied with external power. The power supply unit 13 converts external power into internal power and supplies the internal power to the light source 14 . Specifically, the internal power converted by the power supply unit 13 is further converted by an inverter and supplied to the light source 14 . Then, the light source 14 emits ultraviolet rays.

The ceiling fan 100 further includes a controller 5 , a light receiving section 6 and an operating section 7 . Also, the ceiling fan 100 can be remotely controlled by a remote controller RC. The remote controller RC has a function of transmitting infrared rays to the ceiling fan 100, for example.

The light receiving unit 6 receives infrared rays transmitted from the remote controller RC. The light-receiving unit 6 inputs to the controller 5 the result of receiving the infrared rays transmitted from the remote controller RC. The infrared rays of the remote controller RC include information indicating instructions to the ceiling fan 100, for example. The instruction to the ceiling fan 100 includes, for example, an instruction to rotate the blades 21 of the air blower 2 in a predetermined direction, an instruction to cause the ozone generator 1A to generate ozone, an instruction to emit light to the light source 1B, and an instruction to emit light from the light source 1B. , an instruction to stop the ozone generator 1A, or an instruction to stop the light source unit 1B. Note that the infrared rays of the remote controller RC may include information indicating multiple instructions to the ceiling fan 100 .

The operation unit 7 is operated by the user. The operation unit 7 is, for example, a switch. The operation unit 7 is provided, for example, in a room in which the ceiling fan 100 is installed. Note that the operation unit 7 may be provided outside the room in which the ceiling fan 100 is installed, or may be provided in the ceiling fan 100 . For example, the ceiling fan 100 is switched between an ON state and an OFF state by operating the operation unit 7 . Specifically, by operating the operation unit 7, for example, the main power supply of the ceiling fan 100 is switched between an ON state and an OFF state.

The controller 5 is a microcomputer including a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) and a storage section 55 as a memory. In Embodiment 1, the controller 5 controls each of the harmful substance control section 1 and the blower section 2 . Specifically, the controller 5 controls each of the ozone generator 1A, the light source section 1B, and the blower section 2 .

The storage unit 55 stores computer programs such as software and data. Specifically, the storage unit 55 includes a main storage device such as a semiconductor memory, and an auxiliary storage device such as a semiconductor memory, a solid state drive, and/or a hard disk drive.

The storage unit 55 also stores operation schedules of the blower unit 2 and the harmful substance control unit 1 . Specifically, the storage unit 55 stores the operation schedule of the blower unit 2, the operation schedule of the ozone generator 1A, and the operation schedule of the light source unit 1B. For example, the operation schedules of each of the air blower 2, the ozone generator 1A, and the light source 1B include the scheduled time when each of the air blower 2, the ozone generator 1A, and the light source 1B starts operating, and the operation schedule. Contains the scheduled stop time.

The processor of the controller 5 functions as a fan controller 51 , an ozone controller 52 , a light source controller 53 and a timer 54 by executing computer programs stored in the memory 55 . That is, the controller 5 includes a blower controller 51 , an ozone controller 52 , a light source controller 53 and a timer 54 .

A timer 54 obtains the current time. The timer 54 may measure the time by itself. The timer 54 may include, for example, a real-time clock that ticks the time (standard time). The timer 54 is an example of a "time acquisition unit".

The blower controller 51 controls the blower 2 . The blower control unit 51 controls the blower unit 2 to operate the blower unit 2 or stop the blower unit 2 in operation. Specifically, for example, the blower control unit 51 controls the blower unit 2 based on the operation content of the operation unit 7 by the user. Further, for example, the air blowing control section 51 controls the air blowing section 2 based on, for example, the light receiving result of the light receiving section 6 input by the light receiving section 6 . Further, for example, the blower control unit 51 controls the blower unit 2 based on the result obtained by the timer 54 and the operation schedule of the harmful substance control unit 1 stored in the storage unit 55 . Specifically, for example, the blower control unit 51 compares the current time with the scheduled time registered in the operation schedule of the blower unit 2, and determines that the current time indicates that the blower unit 2 starts operating or It is determined whether or not the scheduled stop time has come. The air blowing control unit 51 operates the air blowing unit 2 when the current time reaches the scheduled time when the air blowing unit 2 starts operating. Further, when the current time reaches the scheduled time at which the operation of the air blower 2 is to be stopped, the air blower control unit 51 stops the air blower 2 .

The ozone control section 52 controls the ozone generator 1A. The ozone control unit 52 controls the ozone generator 1A to operate the ozone generator 1A or stop the ozone generator 1A in operation. Specifically, for example, the ozone control unit 52 controls the ozone generator 1A based on the light receiving result of the light receiving unit 6 input by the light receiving unit 6 . Also, for example, the ozone control unit 52 controls the ozone generator 1A based on the result obtained by the timer 54 and the operation schedule of the ozone generator 1A stored in the storage unit 55 . Specifically, the ozone control unit 52 compares, for example, the current time with the scheduled time registered in the operation schedule of the ozone generator 1A, and determines that the current time indicates that the ozone generator 1A will not operate. It is determined whether or not the scheduled start or stop time has come. The ozone control unit 52 operates the blower unit 2 when the current time reaches the scheduled time at which the operation of the ozone generator 1A is started. Further, the ozone control unit 52 stops the ozone generator 1A when the current time reaches the scheduled time at which the operation of the ozone generator 1A is to be stopped.

Further, the light source control section 53 controls the light source section 1B. The light source control unit 53 controls the light source unit 1B to operate the light source unit 1B or stop the operating light source unit 1B. Specifically, for example, the light source control section 53 controls the light source section 1</b>B based on the light receiving result of the light receiving section 6 input by the light receiving section 6 . Also, for example, the light source control unit 53 controls the light source unit 1B based on the result obtained by the timer 54 and the operation schedule of the light source unit 1B stored in the storage unit 55 . Specifically, the light source control unit 53 compares, for example, the current time with the scheduled time registered in the operation schedule of the light source unit 1B, and determines whether the current time indicates whether the light source unit 1B starts operating or not. It is determined whether or not the scheduled stop time has come. Light source control unit 53 operates blower unit 2 when the current time reaches the scheduled time at which light source unit 1B starts operating. Further, the light source control unit 53 stops the light source unit 1B when the current time reaches the scheduled time when the operation of the light source unit 1B is stopped.

Here, when the operation unit 7 is operated and the ceiling fan 100 is in the ON state, the harmful substance control unit 1 operates. Specifically, for example, when the operation unit 7 is operated and the main power supply of the ceiling fan 100 is on, the light receiving unit 6 receives an instruction to start the operation of the harmful substance control unit 1. Then, the harmful substance control unit 1 starts operating. Therefore, it is possible to provide a standby time for waiting until the harmful substance control unit 1 operates after the user operates the operation unit 7 and before the user operates the remote controller RC. As a result, the user can predict that the harmful substance control unit 1 will start operating, so that the user's nervousness caused by the sudden operation of the harmful substance control unit 1 can be reduced.

When the operation unit 7 is operated and the main power source of the ceiling fan 100 is turned off, for example, the user operates the remote controller RC and the harmful substance control unit 1 responds to an instruction to start operating. Even if the infrared rays are transmitted toward the light receiving unit 6, the harmful substance control unit 1 does not operate. This is because when the main power source of the ceiling fan 100 is off, the power to the light receiving section 6 is turned off, for example, so that the light receiving section 6 is turned off. Further, when the ceiling fan 100 is in the OFF state, for example, even if the current time is the time when the harmful substance control unit 1 is scheduled to start operating, the harmful substance control unit 1 does not operate. Note that when the main power supply of the ceiling fan 100 is off, the light receiving section 6 may be on.

Next, the ceiling fan 100 will be further described with reference to FIGS. 2 and 3. FIG. FIG. 3 is a perspective view showing the ceiling fan 100. FIG. Specifically, FIG. 3 shows the ceiling fan 100 when viewed from the side opposite to the ceiling surface C with respect to the ceiling fan 100 .

As shown in FIG. 3, the housing 30 of the mounting portion 3 has a substantially cylindrical shape. Specifically, in the first embodiment, the housing 30 has, for example, a flat, substantially cylindrical shape. Further, the housing 30 has a facing surface 31 that faces the air blower 2 . Specifically, the facing surface 31 faces the facing surface 26 of the air blower 2 in the direction in which the connecting part 4 extends.

The facing surface 31 has an opening 31h. In Embodiment 1, the facing surface 31 has a plurality of openings 31h. The aperture 31h is, for example, slit-shaped. However, the shape of the opening 31h is not particularly limited. For example, the aperture 31h may have a substantially rectangular shape or a substantially circular shape. Further, in Embodiment 1, the plurality of openings 31h are arranged in a zigzag pattern, for example. In other words, the plurality of openings 31h are staggered along one direction. In other words, the plurality of openings 31h are arranged in a zigzag pattern. However, the arrangement of the openings 31h is not particularly limited.

Ozone is emitted to the outside of the housing 30 through the opening 31h by the ozone generator 12 of the ozone generator 1A generating ozone.

The housing 20 of the air blower 2 has, for example, a flat, substantially cylindrical shape. Moreover, the housing 20 further has a bottom surface 25 . The bottom surface 25 has a substantially circular shape. The bottom surface 25 is the surface of the housing 20 that is farthest from the mounting section 3 . Further, the bottom surface 25 faces the facing surface 26 of the housing 20 in the direction in which the connecting portion 4 extends. Further, for example, when the user is positioned directly below the ceiling fan 100, the bottom surface 25 faces the user in the direction in which the connecting portion 4 extends.

The light receiving section 6 is arranged, for example, on the bottom surface 25 in the first embodiment. However, the arrangement of the light receiving section 6 is not particularly limited. For example, the light receiving section 6 may be arranged on the blade section 21 , may be arranged on the side surface of the housing 20 , or may be arranged on the mounting section 3 .

The air blower 2 includes four blades 21 in the first embodiment. Each of the four blade portions 21 extends from the housing 20 in four directions with the housing 20 as the center.

For example, when the light receiving unit 6 receives an infrared ray corresponding to an instruction to rotate the blade portion 21 in the first rotation direction R1, the air blow control unit 51 of the controller 5 controls the blade portion 21 based on the light receiving result of the light receiving unit 6. controls the motor 23 to rotate in the first rotation direction R1. As a result, the blade portion 21 rotates in the first rotation direction R1 to generate an airflow F1 directed toward the ceiling surface C. As shown in FIG. The first rotation direction R1 is, for example, a direction of clockwise rotation. Note that the first rotation direction R1 may be a direction of counterclockwise rotation.

Further, for example, when the light receiving unit 6 receives infrared light corresponding to an instruction to rotate the blade unit 21 in the second rotation direction R2, the air blow control unit 51 of the controller 5 controls the blade according to the light receiving result of the light receiving unit 6. The motor 23 is controlled so that the portion 21 rotates in the second rotation direction R2. As a result, the blade portion 21 rotates in the second rotation direction R2 to generate an airflow F2 directed away from the ceiling surface C. As shown in FIG. The second rotation direction R2 is a direction of rotation opposite to the first rotation direction R1. That is, the second rotation direction R2 is opposite to the first rotation direction R1.

In the first embodiment, when the light source control unit 53 controls the light source unit 1B (light source 14) to emit ultraviolet rays, the air blow control unit 51 controls the motor so that the blade unit 21 rotates in the first rotation direction R1. 23 to generate the airflow F1. The airflow F<b>1 , for example, sends the air on the side farther from the ceiling surface C than the light source 14 to the side closer to the ceiling surface C than the light source 14 . Therefore, the light source 14 irradiates the air moved by the airflow F1 generated by the blade part 21 with ultraviolet rays, so that the air in which the harmful substances SA are controlled can be effectively moved toward the floor by the airflow F1. As a result, air in which harmful substances SA are controlled effectively circulates in the room.

Further, in Embodiment 1, when the ozone control unit 52 controls the ozone generator 1A to generate ozone, the air blow control unit 51 controls the motor 23 so that the blades 21 rotate in the second rotation direction R2. to generate the airflow F2. Therefore, the airflow F2 generated by the vanes 21 effectively scatters the ozone released into the air. As a result, the harmful substances SA in the air can be effectively controlled. As a result, the air in which the harmful substances SA are controlled effectively circulates in the room.

It is preferable that the blade portion 21 of the ceiling fan 100 changes its rotating direction depending on the season, for example. For example, in winter, it is preferable to generate an airflow F1 directed toward the ceiling surface C in response to rotating the blade portion 21 in the first rotation direction R1. This is because the generation of the airflow F1 moves the warm air staying in the vicinity of the ceiling surface C toward the floor, thereby making it possible to bring the temperature of the air in the room closer to uniformity. Further, for example, in summer, it is preferable to generate an airflow F2 directed away from the ceiling surface C in response to rotating the blade portion 21 in the second rotation direction R2. This is because the user's sensible temperature drops because the airflow F1 directly hits the user in the room. From the above, for example, the operation schedule of each of the air blower 2, the ozone generator 1A, and the light source 1B is the schedule when each of the air blower 2, the ozone generator 1A, and the light source 1B starts operating. may include information about That is, in winter, the blade portion 21 is rotated in the first rotation direction R1 by the air blowing control portion 51, and the light source 14 emits ultraviolet rays. In addition, in summer, the blade portion 21 is rotated in the second rotation direction R2 by the air blowing control portion 51, and the ozone generating portion 12 emits ozone. Therefore, the harmful substances SA in the indoor air can be controlled while appropriately adjusting the indoor temperature according to the season. As a result, a comfortable indoor environment can be realized.

Here, ceiling fan 100 may further include a light emitting unit (not shown). The light emitting unit is arranged in the blower unit 2, for example. Specifically, for example, it is arranged below the blade portion 21 or on the bottom surface 25 of the housing 20 . The light emitting unit emits light to emit visible light, for example. The light emitting unit illuminates the room, for example. That is, in Embodiment 1, the light emitting section is the light source. Specifically, the light emitting unit is, for example, an LED (Light Emitting Diode).

Next, referring to FIG. 4, the blower section 2 will be described. FIG. 4 is a perspective view showing the ceiling fan 100. FIG. Specifically, FIG. 4 shows the ceiling fan 100 when viewed from the ceiling surface C side with respect to the ceiling fan 100 . In order to facilitate understanding of the invention, the mounting portion 3 and the connecting portion 4 are omitted in FIG.

As shown in FIG. 4, in Embodiment 1, the facing surface 26 of the housing 20 of the air blower 2 has an opening h1 and an opening h2. Specifically, the facing surface 26 has a plurality of openings h1 and a single opening h2. The connecting portion 4 (see FIG. 1) is inserted through the opening h2.

The aperture h1 has, for example, a substantially fan shape in the first embodiment. In addition, the shape of the opening h1 is not particularly limited. For example, the aperture h1 may have a substantially circular shape, a substantially rectangular shape, or a substantially annular shape. Moreover, the number of openings h1 is not particularly limited. For example, the number of holes h1 may be singular or plural (three or more).

For example, the cover 27 is fitted in the opening h1 in the first embodiment. The cover 27 is made of, for example, a translucent material. The translucent material is, for example, glass or transparent resin. Therefore, the ultraviolet rays emitted by the light source unit 1B can be emitted to the outside of the housing 20 while preventing foreign matter from entering the housing 20 through the openings h1.

In Embodiment 1, the light source unit 1B may be fixed to the housing 20 by fixing means such as screws, for example. In this case, the light source unit 1B is attached to and detached from the housing 20 using, for example, a tool. That is, the light source unit 1B is detachable from the housing 20. As shown in FIG. Therefore, the light source section 1B can be replaced. As a result, even if the life of the light source unit 1B is short, the ceiling fan 100 can be used for a period longer than the life of the light source unit 1B. Note that the light source unit 1B may be configured to be detachable from the housing 20 without using a tool. For example, the light source unit 1B may be screwed into the housing 20 or may be connected to a connecting section (for example, a connector) arranged inside the housing 20 .
