[0017] Figure 1 1 is a top view showing an example of an installation environment of a spray device according to an embodiment of the present disclosure. Figure 1 As shown by the arrows, the front-to-back direction, the left-to-right direction, and the up-down direction are defined. Figure 1 The environment shown is a room where passengers of a moving object stay, and a plurality of seats 2 are arranged in the front, back, left, and right directions. Here, the moving object refers to vehicles such as cars and buses, trains, ships, airplanes, and spacecraft, for example.

[0018] Figure 1 The seat 2 shown has a seat surface 20 and a backrest 21. Hereinafter, a case where the face of the seated person sitting on the seat surface 20 of the seat 2 faces forward and the back faces backward will be described. The seat 2 can change its posture based on the seated person's instructions. For example, the seat 2 can change the angle of the backrest 21 relative to the seat surface 20.

[0019] exist Figure 1 In the figure, the seats 2 are arranged with two legs arranged in the left-right direction. Other seats 2 are arranged in front and behind the seats 2 arranged in the left-right direction. A spray unit 3 is arranged between the seats 2 with two legs arranged in the left-right direction. The spray unit 3 is equipped with a spray device 1 at the rear. In addition to the spray device 1, the spray unit 3 may also have a cup holder 31, a storage portion such as a storage rack, an armrest, etc. The spray unit 3 will not interfere with each other when the seats 2 arranged on the left and right thereof are in any posture. In addition, the spray unit 3 may also have a driving mechanism for moving the spray device 1 forward, backward, left and right relative to the spray unit 3. Figure 1 Of the two spray devices 1 shown, the spray device 1 located at the rear is arranged at the rear relative to the spray unit 3 as compared with the spray device 1 located at the front. In addition, the spray device 1 may be provided so as to be rotatable relative to the spray unit 3.

[0020] The spray device 1 sprays a mist of liquid atomized toward a seat 2 arranged at least one of the left rear and the right rear of a spray unit 3 equipped with the spray device 1. A target area 40 as a spray target of the spray device 1 is predetermined and arranged above a seat surface 20 of the seat 2 arranged behind the spray unit 3 equipped with the spray device 1. The target area 40 is set to include the face and arms of an average-sized seated person, for example. The spray device 1 is located at the front left side or the front right side of the target area 40.

[0021] Figure 1The seat 2 in which the target area 40 is set is an example of a first seat. The seat 2 located in front of the seat 2 in which the target area 40 is set is an example of a second seat. The seat 2 sandwiching the spray unit 3 with the seat 2 as the second seat is an example of a third seat.

[0022] Figure 2 1 is a perspective view showing a structural example of a spray device 1 according to an embodiment of the present disclosure. Figure 2 As shown, the spray device 1 includes a mist generating unit 10 , a first nozzle 11 , an air supply unit 12 , a second nozzle 13 , and a casing panel 14 . Figure 2 The housing panel 14 shown is part of the housing of the spray device 1. Figure 2 In FIG. 1 , regarding the internal structure of the spray device 1 , only a portion of the housing of the spray device 1 is shown in order to improve visibility.

[0023] The mist generating unit 10 stores a liquid for spraying inside and generates mist by atomizing the liquid. The liquid for spraying is, for example, water and may contain a fragrance or a disinfectant. The first nozzle 11 has a cylindrical shape and guides the mist generated by the mist generating unit 10 toward the first opening 110 of the housing panel 14 and sprays the mist from the first opening 110 to the outside of the spray device 1.

[0024] Figure 3 1 is a top view of the first nozzle 11 as viewed from the first opening 110 side. Figure 3 As shown, the first nozzle 11 is between a first opening 110 provided on the housing panel 14 and a second opening 111 provided on the mist generating unit 10. The opening area of ​​the first opening 110 is larger than that of the second opening 111. An ultrasonic vibrator 112 is provided at the second opening 111 or at a position near the second opening 111. A supply hole 113 for supplying liquid stored in the mist generating unit 10 is provided at the center of the ultrasonic vibrator 112. The ultrasonic vibrator 112 atomizes the liquid supplied by the supply hole 113 through ultrasonic vibration. The mist generating unit 10 can adjust the particle size, spray amount, etc. of the mist by changing the hole diameter and the number of holes of the supply hole 113 at the center of the ultrasonic vibrator 112.

[0025] Figure 2 The air supply unit 12 shown generates an air flow. Figure 2The air supply unit 12 shown is a blower, and ejects an air flow from a nozzle 121 to a second nozzle 13. The second nozzle 13 has a cylindrical shape and is arranged at a position lower than the first nozzle 11. The second nozzle 13 guides the air flow ejected from the air supply unit 12 to a third opening 130 of a casing panel 14, and ejects the air from the third opening 130 to the outside of the spray device 1. A slit 114 is provided in the third opening 130. The air supply unit 12 and the second nozzle 13 pre-set the direction of the nozzle 121, the nozzle shape, the wind speed, the wind volume, etc. so that the ejected air flow reaches at least the target area 40.

[0026] The mist sprayed from the first nozzle 11 is rolled up by the air flow sprayed from the second nozzle 13 outside the spray device 1. By using the air flow sprayed from the second nozzle 13 to roll up the mist, the mist can be sprayed farther than when only the mist is sprayed. In addition, by making the air flow reach the target area 40 together with the mist, the mist sprayed toward the seated person of the seat 2 can be quickly vaporized, and the seated person can be efficiently cooled.

[0027] use Figure 4 , the target area to be sprayed by the spray device 1 is described. Figure 4 1 is a side view showing an example of an installation environment of a spray device according to an embodiment of the present disclosure. Figure 4 In the setting environment shown, the seat 2 and the spray unit 3 are arranged on the ground F parallel to the horizontal plane. Figure 4 As shown, the target area 40 for spraying is set at a position above the seat surface 20 of the seat 2 located behind the spray unit 3 on which the spray device 1 is mounted.

[0028] exist Figure 4 In the figure, arrows are used to illustrate the Figure 2 The ejection port 121 is shown facing a direction 41 of the third opening 130, ie, a direction in which the second nozzle 13 mainly guides the air. The direction 41 is inclined upward at a predetermined angle θ relative to the horizontal direction (where θ is greater than 0 degrees and less than 90 degrees).

[0029] The mist sprayed from the first opening 110 merges with the airflow between the third opening 130 of the second nozzle 13 provided in the cabinet panel 14 and the target area 40. The airflow sprayed from the third opening 130 rolls up the mist sprayed from the first opening 110 and makes the mist reach the target area 40.

[0030] When mist is blown down from the ceiling of the room where the seat 2 is installed, the mist easily falls on the hair of the seat 2 seated person. However, hair is less likely to receive the cooling effect of mist than skin. By spraying the mist diagonally upward from a position lower than the seated person's face on the seat 2, it is easy to spray the mist at exposed skin areas such as the face and arms of the seated person.

[0031] The spray device 1 may be configured to separately control the spraying of mist from the first nozzle 11 and the spraying of air flow from the second nozzle 13. For example, the spraying of mist may be stopped during the spraying of air flow. Thus, the mist sprayed toward the seated person can be effectively vaporized.

[0032] (Effect)

[0033] As described above, according to the spray device 1 of this embodiment, the following effects can be obtained.

[0034] The spray device 1 sprays a mist obtained by atomizing a liquid toward a target area 40 predetermined at a position above a seat surface 20 of a seat 2. The spray device 1 includes: a mist generating unit 10 generating mist; a first nozzle 11 spraying the mist generated by the mist generating unit (10) toward the outside of the spray device 1; an air supply unit 12 generating an air flow; and a second nozzle 13 disposed at a position below the first nozzle 11 and spraying the air flow toward the outside of the spray device 1 upward from a horizontal direction. The mist sprayed from the first nozzle 11 merges with the air flow between the second nozzle 13 and the target area 40. According to the above structure, the second nozzle 13 is disposed at a position below the first nozzle 11, and the air flow is sprayed from the second nozzle 13 upward from a horizontal direction, so that the mist sprayed from the first nozzle 11 merges with the air flow between the second nozzle 13 and the target area 40, thereby making it possible to roll up the mist sprayed from the first nozzle 11 by the air flow, so that the mist is scattered farther, and the spray object in the target area 40 is sprayed efficiently.

[0035] In addition, if the mist and the air flow are combined inside the nozzle, the mist adheres to the inner wall of the nozzle, and the liquid may accumulate inside the nozzle. According to the above structure, since the mist and the air flow are combined outside the spray device 1, it is possible to prevent the liquid from accumulating inside the first nozzle 11 and the second nozzle 13.

[0036] When the front side of the seated person sitting on the seat surface 20 is set to the front and the back side is set to the back, the second nozzle 13 is located at the front left side or the front right side of the target area 40. According to the above structure, the spray can be sprayed from the left and right front and below the seated person, so it is easy to spray toward the exposed parts of the human body such as the face and arms of the seated person, and the human body can be cooled efficiently.

[0037] Another seat 2 (second seat) is arranged in front of the seat 2 (first seat) defining the target area 40, and the spray device 1 is arranged outside the seat 2 defining the target area 40 and the seat 2 in front of it. More specifically, the spray device 1 is mounted on the spray unit 3, and the spray unit 3 is arranged between the seats 2 where the legs are arranged in front of the seat 2 defining the target area 40. According to the above structure, the spray device 1 can spray the mist toward the target area 40 regardless of the posture of the seat 2 located on the left and right of the spray unit 3.

[0038] (Variation)

[0039] In the above embodiment, the spray device 1 is provided in the spray unit 3, and the spray unit 3 is arranged between the two seats 2 arranged side by side. However, the location where the spray device 1 is provided is not limited to the spray unit 3. For example, the spray device 1 can be directly fastened to Figure 4 The floor F shown in the figure may also be provided on the back side of the backrest 21 of the seat 2. When the spray device 1 is provided on the back side of the backrest 21 of the seat 2, it is preferred that when the backrest 21 of the seat 2 rotates relative to the seat surface 20, the spray device 1 is preferably rotated in the opposite direction to the backrest 21 in such a manner as to maintain the state in which the spray device 1 faces the target area 40. In addition, when the spray device 1 is arranged in a narrow part such as the backrest 21 of the seat 2, it is preferred to appropriately adjust the nozzle shapes of the first nozzle 11 and the second nozzle 13, the direction of the ejection port 121 of the air supply unit 12, the wind speed, the wind volume, etc.

[0040] In the above embodiment, the spray device 1 is set in the environment where the passengers of the moving object stay, but it is not limited to this. For example, even if the spray device 1 is set in an environment where a plurality of seats 2 are arranged, such as a movie theater, the same effect as the case of setting it in the moving object can be achieved.

[0041] In the above embodiment, the seat 2 includes the seat surface 20 and the backrest 21 , but the present invention is not limited thereto. The seat 2 may have any shape as long as it includes at least the seat surface 20 .

[0042] In the above-mentioned embodiment, the air supply unit 12 is a blower, but it is not limited to this. For example, an axial flow fan or a compressor may be used as the air supply unit 12. In addition, when a compressor is used for the air supply unit 12, the operating sound is loud, which sometimes causes discomfort to the seated person of the seat 2. In addition, the compressor requires a tank for storing compressed air, and the continuous air supply time may be limited due to the capacity of the tank. As in the above-mentioned embodiment, when a blower is used as the air supply unit 12, a tank for storing compressed air is not required, so compared with the case of using a compressor, the air can be continuously supplied for a long time and the operating sound is quiet.

[0043] The present disclosure is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims. Embodiments obtained by appropriately combining technical means disclosed in different embodiments are also included in the technical scope of the present disclosure.
