The photocatalyst supports the filter 221, for example, it can be set to 0.4 A medium-high-performance filter with a collection rate of micrometer particles of less than 99%.

As the collection filter 222 , for example, a pseudo-high-efficiency particle air filter (High Efficiency Particulate Air Filter) having a collection rate of 0.3 μm particles of 90% or more can be used. In addition, the collection filter 222 is not essential, and may be omitted.

By using the air cleaning mechanism 22 having such a configuration, it is possible to not only decompose and deactivate bacteria, viruses, etc., but also suppress odor and remove particulate matter by removing odor causative substances, thereby enabling passengers to be improved. of comfort. This trap filter 222 is capable of decomposing NO _X and the like and removing fine particles such as PM 2.5.

Although not shown, a light shielding member for shielding ultraviolet light may be provided before and after the air cleaning mechanism 22 . As the light-shielding member, it is desirable to use a light-shielding member that shields light without hindering the passage of air. For example, a member using a plurality of punched metal plates having a plurality of holes and staggered holes can be used. The positions are overlapped with a predetermined interval.

The fan 27 is used for inhalation (inhalation) and discharge (blowout) of air, and is provided downstream of the air cleaning mechanism 22 (on the side opposite to the air intake port 21). The air introduced into the main body part 24 from the air inlet 21 by the fan 27 is purified by the air cleaning mechanism 22 to become clean air, and passes through the flow path in the main body part 24 and the flow path in the arm part 25, On the other hand, the air is blown out in layers from the air outlet 23 and the upper air outlet 26 . In addition, the position where the fan 27 is installed is not limited to the position shown in the figure. For example, it may be installed in the vicinity of the air outlet 23 and the upper air outlet 26, or in the vicinity of the air outlet 23 and the upper air outlet 26 and the main body portion 24. set the fans on both sides. Further, as the fan 27, a vertical fan (Line Flow Fan (registered trademark)) or a fan in which a plurality of small fans are arranged in a vertical direction can be used.

By blowing air in layers from the air outlet 23 and the upper air outlet 26, air barriers, that is, air barriers (also referred to as air curtains) can be formed on both sides and above the seat 10, and the intrusion of bacteria, viruses, etc. can be suppressed. In the space partitioned by the air barrier, air infection of the seat occupant of the seat 10 can be suppressed.

In addition, the air barrier forming unit 2 includes a sensor 28 for detecting the state of air sucked in from the air intake port 21, and a display 29 for displaying the air detected by the sensor 28 status. As the sensor 28, any one of a temperature sensor, a humidity sensor, a odor sensor, and a dust sensor, or a combination of one or more sensors can be used. In addition, although it has not yet been put into practical use, it is possible to use a sensor (biosensor, etc.) that can detect viruses, bacteria, etc. as the sensor 28 in the future.

The display 29 is provided so as to face the front surface of the main body portion 24 (the portion above the upper air outlet 26 ). The display 29 is composed of, for example, a liquid crystal display, and displays the state of the air sucked in from the air inlet 21 . However, it is not limited to this, and it is also possible to have a configuration in which a small terminal is provided separately from the air barrier rib forming unit 2, the small terminal has a display 29, and wireless communication is performed between the air barrier rib forming unit 2 and the small terminal, Thereby, the state of the air can be displayed on the display 29 of the small terminal. By arranging the small terminal on the armrest of the seat 10 or the like, the seated person can more easily confirm the state of the air without turning his head or standing up.

In addition, the state of the air detected by the sensor 28 can also be configured to be output to an external device by wireless communication or the like. Thereby, the distribution of the state of the air in the vehicle (in the passenger compartment, etc.) (eg, temperature distribution, odor distribution, etc.) can be analyzed, for example, using an external device, and based on the analysis results, for example, development of new airframes and aircraft air conditioners can be performed. Design (air conditioning analysis), etc. In addition, the display for displaying the analysis results is provided in the cockpit or the like, whereby the state distribution of the air can be grasped even in the cockpit or the like.

In addition, the air barrier forming unit 2 may have an air volume adjustment mechanism that can adjust the blowing amount of the clean air from the air outlet 23 and the upper air outlet. The air volume adjustment mechanism adjusts the rotation number of the fan 27 by appropriate control such as control of the drive current of the fan 27 or PWM (pulse width modulation) control, thereby adjusting the blowing volume of the clean air. In addition, the air volume adjustment mechanism may be configured so that the blowing amount of the clean air from the air outlet 23 is zero, that is, the blowing of the clean air can be stopped (an air barrier is formed).

Regarding the adjustment of the air volume, a controller that can be operated by the seated person may be provided on the armrest of the seat 10 or the like, so that each air barrier forming unit 2 (or each air barrier forming unit 2 (or each air barrier forming unit 2) can be individually adjusted by the operation of the controller. seat 10). Furthermore, it is also possible to configure the air volume of all the air barrier forming units 2 in the vehicle (in the passenger compartment) to be managed collectively without being able to individually adjust the air volume by the seated person. As described above, when an external device is used to analyze the distribution of the state of the air, the external device can be configured to automatically adjust the air volume (blowout volume) of each air barrier-rib forming module 2 . For example, based on the analysis result of the distribution of the air state, control such as increasing the air volume (blowout volume) of the air barrier-rib forming unit 2 can be performed in a region where the detected odor value is large.

Furthermore, the air barrier forming unit 2 may have a blowing direction control mechanism that controls the blowing from the blowing port 23 and the upper side according to the reclining (reclining) angle of the backrest 11 (the angle between the seat surface and the backrest 11 ). The blowing direction of the clean air from the outlet 26 . The blowing direction control mechanism controls the angle of the fins 23a (refer to FIG. 3 ) provided in the blowing outlet 23 according to the reclining angle of the backrest 11, thereby allowing clean air to be directed to the reclining angle regardless of the reclining angle. Blow out from the front. In addition, the blow-out direction control mechanism may be configured to select the blow-out direction of the clean air from the blow-out port 23 and the upper side blow-out port 26 to be parallel to the seat surface (floor surface) or to be perpendicular to the backrest 11 direction. Furthermore, once the blowing direction of the clean air is toward the floor surface side, the dust on the floor surface will be raised, which may cause adverse effects on the surroundings. Therefore, the blowing direction of the clean air is preferably horizontal with respect to the floor surface. Or a direction higher than the horizontal direction.

Although the illustration is omitted in FIGS. 1 to 3, in order to be able to cope with the seat 10 having a different size of the headrest 12, the arm portion 25 is desirably configured to be extendable and retractable in the left-right direction. The specific structure of the mechanism for extending and contracting the arm portion 25 is not particularly limited. For example, as shown in FIG. 25a and 25b are constituted so as to overlap each other, and the overlapping width is changed, whereby the arm portion 25 can be expanded and contracted. In the example shown in FIG. 4, protrusions 251 protruding outward are provided on the outer wall 25a of the inner arm portion 25 of the overlapping portion, and the outer wall 25b of the outer arm portion 25 of the overlapping portion is spaced apart in the left-right direction. A plurality of concave portions 252 for accommodating the protrusions 251 are provided, and the concave portions 252 for accommodating the protrusions 251 are appropriately selected, whereby the expansion and contraction width of the arm portion 25 in the left-right direction can be adjusted. In the example of FIG. 4, the protrusion 251 is energized (pushed) outward by the energizing member 253 such as a spring, whereby the recess 252 for accommodating the protrusion 251 can be easily changed, that is Adjust the telescopic width of the arm portion 25 . However, the mechanism shown in FIG. 4 is merely an example, and the specific configuration of the mechanism for extending and contracting the arm portion 25 is not limited to the example shown in the figure.

The power supply to the air cleaning mechanism 22, the sensor 28, etc. may be configured to be performed by a built-in battery, or may be configured to supply power from the outside. In the case of supplying power from the outside, for example, it is sufficient to connect the air barrier-rib forming assembly 2 to an external power source such as a power source of a vehicle. As a form of connection to an external power source, a general power cord for supplying AC or DC power can be used, for example, a USB cable can be used for power supply, and power can also be supplied from a cigarette lighter socket.

Further, in the present embodiment, since the air barrier forming member 2 is provided on the headrest 12, in order not to give the seated person an uncomfortable feeling due to the sound of the fan 27 and the sound of the air current, the soundproof property is more preferable. The outer walls of the main body portion 24 and the arm portion 25 and the like are constituted by high material and structure. For example, at least a part of the outer walls of the body portion 24 and the arm portion 25 may be provided with a sound absorbing structure using sound absorbing materials such as glass wool and urethane sponge, embossed fabrics, and concave-convex boards.

In the present embodiment, the case where the infection suppressing device 1 is applied to the seat 10 for one person has been described. However, since the air barrier forming unit 2 in the present embodiment is structured to be attached to the headrest 12, it is not necessary to The present embodiment is also applicable to a bench seat in which the headrest 12 is individually provided, not limited to the seat 10 for one person.
