The backrest 22 side of the seat 11 is the rear side, and the opposite side is the front side. . Moreover, the direction of the armrest 23 side of the seat 11 is defined as the left-right direction.

As shown in FIG. 1, the air conditioner 12 includes a supply port 31 that supplies air from above the vehicle 1 in the vertical direction to the interior 1a, and a plurality of exhaust ports 32 that exhaust the air in the interior 1a to the floor of the vehicle 1. and an air conditioner 33 disposed under the floor of the vehicle 1 for processing the air supplied to the interior 1a. The plurality of air outlets 32 correspond to the plurality of seats 11 and are arranged at the feet of each seat 11. - 特許庁The air discharged under the floor from each air outlet 32 at the foot of each seat 11 reaches the air conditioner 33 via the air conditioning duct 34 under the floor, and after being subjected to ventilation processing and temperature adjustment processing, The air is supplied to the room 1a from the supply port 31 above the vehicle 1 via the air conditioning duct 34 inside. That is, the air conditioning equipment 12 has a configuration in which air is supplied from above the vehicle 1 and exhausted under the floor.

(Configuration of infection control device)
As shown in FIG. 1, the infection control device 40 has a plurality of air barrier forming units 41 attached to the upper portions of the backrests 22 of the plurality of seats 11 aligned in the left-right direction and the front-rear direction. .

As shown in FIG. 3 , each air barrier forming unit 41 is positioned at the upper end of the backrest 22 in the vertical direction, and includes an air intake arrangement portion 51 provided with an air intake 61 and side ends of the backrest 22 in the left and right direction. , and has a pair of left and right outlet installation portions 52 in which outlets 81 are formed. That is, the air barrier forming unit 41 is attached above the backrest 22 of the seat 11 so as to surround the upper surface and both side surfaces of the backrest 22 .

As shown in FIG. 4 , the intake port arrangement portion 51 includes a case 60 forming an outer shell, an intake port 61 arranged behind the case 60 , and an inner portion formed in the case 60 and communicating with the intake port 61 . a flow path 62; an air cleaning mechanism 63 disposed on the intake port 61 and the internal flow path 62; , and two fans 64 for the intake (intake) and exhaust (blow) of air.

The air intake port 61 is an opening that is arranged in the rear of the case 60 and in the center position in the left-right direction, and is formed in a rectangular shape (rectangular shape) that is elongated in the left-right direction. The air intake port 61 opens toward the rear of the seat 11 and sucks air on the rear seat 11 at the upper end of the backrest 22 .

The internal flow path 62 of the intake port arrangement portion 51 has two branch flow paths 62a that branch left and right from a portion that communicates with the intake port 61. communicates with

The air purification mechanism 63 decomposes and inactivates bacteria and viruses in the air introduced from the intake port 61, suppresses odors, and removes particulate matter. The air purification mechanism 63 includes a pre-filter 71 arranged above the intake port 61, a photocatalyst-carrying filter 72 arranged behind the pre-filter 71, and arranged between the pre-filter 71 and the photocatalyst-carrying filter 72. and a light source 73 .

The pre-filter 71 is a collection filter that collects dust on the intake port 61 .

The photocatalyst-carrying filter 72 carries a photocatalyst that exhibits a photocatalytic function when irradiated with ultraviolet rays from the light source 73 and collects dust.

The light source 73 irradiates the photocatalyst-carrying filter 72 with ultraviolet rays. In this embodiment, a deep ultraviolet LED (Light Emitting Diode) that emits deep ultraviolet rays (for example, ultraviolet rays having a wavelength of 250 nm or more and 280 nm or less) is used for the photocatalyst carrying filter 72 .

By using the air purification mechanism 63 having such a configuration, it is possible not only to decompose and inactivate bacteria and viruses, but also to suppress odors by removing odor-causing substances and to remove particulate matter. It can improve comfort. This air purification mechanism 63 can decompose NO _x (nitrogen oxide) and the like, and can also remove fine particles such as PM2.5.

Each fan 64 is a small DC fan arranged in each branch flow path 62a, and sucks air from the intake port 61 and blows clean air from the blowout port 81. As shown in FIG. The wind velocity of the clean air blown out from each blower outlet 81 can be controlled by the drive amount of each fan 64 and the opening area of each blower outlet 81 . Although the details will be described later, the wind velocity of the clean air blown out from the air outlet 81 is controlled so that the wind velocity of the clean air facing the passengers is 0.3 m/sec or less.

Each blowout opening arrangement part 52 includes a case 80 forming an outer shell, a blowout opening 81 arranged in front of the lower part of the case 80, an internal flow path 82 formed in the case 80 and communicating with the blowout opening 81, It has

The internal flow path 82 of each air outlet arrangement portion 52 communicates with each branch flow path 62 a of the air inlet arrangement section 51 on the root side, and communicates with the air outlet 81 on the tip side. The air sucked from the intake port 61 is purified into clean air by the air purification mechanism 63, and then flows through each branch flow path 62a of the intake port arrangement portion 51 and the internal flow path of each blowout port arrangement portion 52. It passes through 82 and reaches each blower outlet 81 of each blower outlet arrangement part 52, and is blown forward from each blower outlet 81. As shown in FIG.

The air outlet 81 is arranged at the front of the lower part of the case 80, and is arranged on the slit-shaped slit opening 91 extending in the vertical direction, and is arranged on the slit opening 91, and changes the blowing direction of the clean air to the inward direction in the left and right direction. fins 92; In the air outlet 81 , vertically extending stratified clean air is blown out through a vertically extending slit opening 91 . On the other hand, as shown in FIG. 5, the air outlet 81 changes the direction in which the layered clean air is blown inward in the left-right direction by means of the fins 92, and the air outlet 81 directs the layered clean air to the front seat. 11 (in FIG. 5, the illustration of the air barrier forming unit 41 of the front seat 11 is omitted for ease of explanation). That is, the air outlet 81 blows clean air in layers from the side ends of the backrest 22 of the seat 11 toward the back surface of the backrest 22 of the seat 11 in front. Specifically, the air outlet 81 blows out stratified clean air toward the central portion of the rear surface of the backrest 22 in the left-right direction. The stratified clean air blown out from the outlet 81 forms an air barrier separating the inside and the outside. This air barrier prevents the air from the adjacent seat 11 from entering above the seat 11 to which the air barrier forming unit 41 is attached. The vertical position of the air outlet 81 is aligned with the position of the face of a typical passenger seated on the seat 11 .

In FIG. 5, the stratified clean air currents blown out from the left and right air outlets 81 are tilted inward with respect to the center line O of the seat 11 when viewed from above, and the backrest of the seat 11 in front is blown out. 22 at an angle of less than 90 degrees. The inclination angle of the stratified clean air current with respect to the center line O of the seat 11 is preferably 10 degrees or more and 60 degrees or less, more preferably 30 degrees or more and 45 degrees or less.

Note that the right and left clean air streams may collide with each other. The virtual impingement point P of the clean air stream may be in front of the back of the backrest 22 of the front seat 11 . In this case, the distance from the seat 11 to the imaginary collision point P is shorter than the distance between the seat 11 and the front seat 11, forming an approximately triangular air barrier when viewed from above. Also, the virtual impingement point P of the clean air stream may exceed the back surface of the backrest 22 of the front seat 11 . In this case, the distance from the seat 11 to the imaginary collision point P is longer than the distance between the seat 11 and the front seat 11, and a substantially trapezoidal air barrier is formed in plan view.
In addition, in this embodiment, the clean air is blown out toward the backrest 22 of the seat 11 in front, but the blowing direction of the clean air is not limited to the above aspect. For example, when the air barrier forming unit 41 is attached to the seat 11 in the front row, clean air may be blown toward the front wall to form an air barrier around the passenger's face. The distance from the seat 11 to the imaginary collision point P may be made shorter than the distance between the seat 11 and the front wall to form an approximately triangular air barrier when viewed from above. Also, the distance from the seat 11 to the imaginary collision point P may be set longer than the distance between the seat 11 and the front seat 11 to form a substantially trapezoidal air barrier when viewed from above.
Further, by configuring the distance from the seat 11 to the virtual collision point P to be shorter than half of the distance between the opposing seats 11, a plurality of front and rear seats 11 are rotated to form box seats so that passengers face each other. Even if the passengers are seated on the same seat, the effect of suppressing infection between passengers can be expected.

Further, as shown in FIG. 6 , the stratified clean air blown from the outlet 81 toward the rear surface of the backrest 22 hits the rear surface of the backrest 22 . Since the back surface of the backrest 22 slopes downward from the rear to the front, most of the clean air that hits the back surface of the backrest 22 flows downward along the back surface. As a result, an air current flowing downward from above is generated on the seat 11 . As shown in FIG. 7 , each seat 11 generates an air current flowing from above to below, so that the air supplied from the supply port 31 passes over each seat 11 as the entire vehicle 1 and reaches the feet of each seat 11 . An airflow is generated to be discharged under the floor from each exhaust port 32 of the . In this way, the air outlet 81 blows out stratified clean air toward the back surface of the backrest 22 of the seat 11 in front, thereby clearing the air current on the seat 11 and the vehicle interior 1a.

Further, the wind velocity of the stratified clean air blown out from the outlet 81 is controlled (adjusted) so that the wind velocity of the stratified clean air facing the passenger seated on the seat 11 is 0.3 m/sec or less. The wind speed of 0.3 m/sec or less is equivalent to the wind speed of the airflow generated by the steam generated during perspiration, and is a wind speed that does not cause discomfort such as fatigue, coldness, and noise. That is, the air-barrier forming unit 41 is arranged such that the wind velocity of the stratified clean air facing the passenger is a wind velocity (0.3 m/sec or less) that does not cause discomfort to the passenger. It is configured to blow out. When the clean air has a wind velocity of 0.3 m/sec or less, the formation of an air barrier suppresses infection, while allowing passengers seated next to each other to converse without discomfort.

According to the Beaufort wind force scale table, if the wind speed is 0.15 m/sec or less, you cannot feel the wind on your face. Also, according to ISO7730, when the wind speed exceeds 0.15 m/sec, there is a risk of feeling cold. Therefore, if only the passenger's discomfort is considered, the wind velocity of the stratified clean air blown out from the outlet 81 should be 0.15 m/sec or less for the stratified clean air facing the passenger seated on the seat 11. More preferably, it is controlled so that

In addition, if the wind speed is 0.15 m/sec or more, the air barrier formed by stratified clean air can provide sufficient spatial isolation performance. Therefore, considering the spatial isolation performance of the air barrier formed by the stratified clean air, the wind speed of the stratified clean air blown out from the blowout port 81 is 0.00% for the stratified clean air facing the passenger seated on the seat 11. It is preferable that the speed is controlled to be 0.15 m/sec or more. In other words, considering the spatial isolation performance of the air barrier formed by the layered clean air in addition to the passenger's discomfort, the wind speed of the layered clean air blown out from the outlet 81 faces the passenger seated on the seat 11. More preferably, the wind velocity of the stratified clean air is controlled to be 0.15 m/sec or more and 0.3 m/sec or less.

More specifically, the wind speed of the entire air barrier formed by stratified clean air is 0.15 m/sec or more and 0.3 m/sec or less, and the wind speed of the wind around the face of the passenger in the air barrier is 0.15 m/sec. It is preferable to control the wind speed of the stratified clean air blown from the blower outlet 81 so as to be as follows.

(Action and effect of embodiment)
As described above, according to the configuration of the above-described embodiment, the air outlet 81 blows out a stratified clean air toward the back of the backrest 22 of the seat 11 in front, thereby generating an air current flowing from above to below on the seat 11. In the vehicle 1 equipped with an air conditioner 12 that supplies air from above and exhausts it under the floor, an air flow passing over each seat 11 can be generated. As a result, it is possible to suppress the circulation of air between the adjacent seats 11, thereby improving the effect of suppressing infection.

In addition, according to the configuration of the above-described embodiment, since the blow-out port 81 is configured to blow out stratified clean air toward the inside, the clean air can be brought closer to the passenger compared to a configuration in which the stratified clean air is blown out in parallel in the front-rear direction. It is possible to ventilate the air in the vicinity of the passenger. As a result, the air in the vicinity of the passenger can be further purified.

Further, according to the configuration of the above embodiment, the intake port 61 is arranged at the position of the upper end of the backrest 22, so that the air that hits the backrest 22 and flows upward can be recovered. As a result, it is possible to prevent the air on the seat 11 from rising upward in the room 1a and moving to another seat 11.例文帳に追加

Further, according to the configuration of the above-described embodiment, the air barrier forming unit 41 includes the air intake opening portion 51 positioned at the upper end portion of the backrest 22 and the air outlet opening portion 52 positioned at the side end portion of the backrest 22. Since it is integrally provided, the air cleaning mechanism 63, the fan 64, etc. are not required compared to the configuration in which the units located at the side ends of the backrest 22 perform intake, air purification, and clean air blowout. In addition, by adding the built-in mechanism, it is possible to improve the sterilization function and the deodorant function, add the aroma function, and the like.

Further, according to the configuration of the above-described embodiment, since the exhaust port 32 of the vehicle 1 is arranged at the foot of each seat 11, the air barrier forming unit 41 easily generates an airflow passing over the seat 11. ing.

Further, according to the configuration of the above-described embodiment, by setting the wind speed of the layered clean air facing the passenger to 0.3 m/sec or less, the clean air blowing out from the air outlet 81 causes discomfort (such as coldness, fatigue, fatigue, etc.). noise) can be suppressed. Furthermore, passengers seated next to each other can talk without feeling uncomfortable.
