DETAILED DESCRIPTION OF THE INVENTION

[0010] Examples of the present disclosure will be described below with reference to the drawings. Note that the following embodiment is an example of the present invention and does not limit the technical scope of the present invention. Furthermore, each drawing described in the embodiment is a schematic drawing, and the ratios of the sizes and thicknesses of the components in each drawing do not necessarily reflect the actual dimensional ratios.

[0011] In addition, in the following explanation, when viewing the air-conditioning space generation system 1 from the front, the right direction is defined as the positive x-axis direction, the left direction is the negative x-axis direction, the up direction is the positive z-axis direction, the down direction is the negative z-axis direction, the front direction is the positive y-axis direction, and the rear direction is the negative y-axis direction.

[0012] Example 1 An overview of an air-conditioned space generating system 1 according to the first embodiment will be described.

[0013] As shown in Figures 1, 2, and 3, the air-conditioning space generating system 1 is composed of an exterior ceiling 10, an interior ceiling 20, a wall surface 30, a first side wall 40, a second side wall 50, an air conditioner 60, and a housing 100.

[0014] The housing 100 has the shape of a bench on which a user can sit, and by blowing out conditioned air, creates an air-conditioned space around the user. Air conditioning includes at least one of heating and cooling. Hereinafter, the air-conditioned space will be referred to as the "air-conditioned space."

[0015] The housing 100 has a base plate 101 , a front surface 102 , a front opening 103 , a front surface 105 , a front opening 106 , an upper surface 107 , an upper opening 108 , a lower surface 109 , and a rear surface 110 .

[0016] The lower surface 109 is in contact with the ground 70. The rear surface 110 is in contact with the wall surface 30.

[0017] Top surface 107 indicates the end surface on the upward direction side, and has upper opening 108. Upper opening 108 serves as an outlet for discharging cooling airflow 301 during cooling operation, and as an intake for drawing in heating airflow 302 during heating operation.

[0018] The front surface 105 indicates the end surface on the forward side, and has a front opening 106. The front opening 106 serves as an intake port that draws in cooling airflow 301 during cooling operation, and as an outlet port that releases heating airflow 302 during heating operation.

[0019] The seat panel 101 represents the seat surface portion of the housing 100. The seat panel 101 is provided so as to protrude forward from the front surface 105. The front end 101a represents the end of the seat panel 101 on the front side.

[0020] The front face 102 indicates a lower portion of the front end 101a, and has a front face opening 103. The front face opening 106 is located between the front face opening 103 and the air conditioner 60. During cooling operation, a cooling airflow 301 passes through the front face opening 106 on the rear side, and during heating operation, a heating airflow 302 passes through the front face opening 106 on the front side.

[0021] An air conditioner 60 is disposed on the lower surface 109. The air conditioner 60 performs cooling operation or heating operation.

[0022] The wall surface 30, the first side wall 40, and the second side wall 50 are each a rectangular surface extending in the vertical direction.

[0023] The housing 100 is disposed between the first side wall 40 and the second side wall 50. The wall surface 30 is disposed on the rear side of the housing 100.

[0024] An inner ceiling 20 is installed above the housing 100 on the wall surface 30. Furthermore, an outer ceiling 10 is installed above the inner ceiling 20.

[0025] The first side wall 40 has a first outer wall portion 41, a first inner wall portion 42, and a first front portion 43. The first outer wall portion 41 indicates the outer wall portion of the first side wall 40. The first inner wall portion 42 indicates the inner wall portion of the first side wall 40. The first inner wall portion 42 may be in contact with the outer ceiling 10, the inner ceiling 20, and the housing 100, respectively. The first front portion 43 is the front portion of the first side wall 40.

[0026] The second side wall 50 has a second outer wall portion 51, a second inner wall portion 52, and a second front portion 53. The second outer wall portion 51 indicates the outer wall portion of the second side wall 50. The second inner wall portion 52 indicates the inner wall portion of the second side wall 50. The second inner wall portion 52 may be in contact with the outer ceiling 10, the inner ceiling 20, and the housing 100, respectively. The second front portion 53 is the front portion of the second side wall 50.

[0027] The first side wall 40 and / or the second side wall 50 has the role of preventing the conditioned airflow (cooling airflow 301 or heating airflow 302) from being disturbed by outside wind, which makes it easier to maintain the air-conditioned space.

[0028] An inner ceiling 20 is installed on the wall surface 30 above the housing 100. The inner ceiling 20 serves to guide the air conditioning airflow (cooling airflow 301 or heating airflow 302). The inner ceiling 20 has an extension 21 and a protrusion 22.

[0029] The protruding portion 22 protrudes forward from the wall surface 30 and is connected to the extension portion 21. The protruding portion 22 has a rectangular surface that extends horizontally.

[0030] Extension 21 is connected to protrusion 22 and is provided so as to bend downward. Tip 21a is the front end of extension 21 and indicates the tip of extension 21. In other words, tip 21a of the inner ceiling indicates the tip of the part that plays a role in guiding the air flow.

[0031] As shown in Fig. 4, in the yz plane, the direction of the tangent 210 of the extension 21 is inclined so that the downward angle increases toward the front side. Here, the direction of the tangent 210 may be inclined so that it faces downward even more than in the shape of Fig. 4. For example, near the tip 21a, the direction of the tangent 210 may be roughly parallel to the vertical direction, or may be inclined so that it narrows inward as it extends downward. Near the tip 21a, the angle between the tangent 210 and the y axis ranges from 75 to 100° or 80 to 95°, for example.

[0032] An exterior ceiling 10 is installed above the interior ceiling 20. The exterior ceiling 10 serves to prevent the air-conditioned airflow (cooling airflow 301 or heating airflow 302) from being disturbed by outside wind. This makes it easier to maintain the air-conditioned space. The exterior ceiling 10 is a rectangular surface that extends horizontally.

[0033] The outer ceiling 10 has a front portion 11, an upper surface 12, and a lower surface 13. The front portion 11 is the end surface of the outer ceiling 10 on the forward side. The upper surface of the outer ceiling 10 is referred to as the upper surface 12. The lower surface of the outer ceiling 10 is referred to as the lower surface 13. The lower surface 13 and the wall surface 30 are in contact with each other.

[0034] The tip portion 11, the first front portion 43, and the second front portion 53 are located, for example, on the same plane. Also, the tip portion 11, the first front portion 43, and the second front portion 53 are located further forward than the tip end portion 21a.

[0035] Next, the airflow during cooling of the air-conditioned space generating system 1 will be described with reference to Fig. 2. During cooling operation, the air conditioner 60 draws air through the front opening 103 and the front opening 106. The drawn air is released from the upper opening 108 as cooling airflow 301.

[0036] In this way, in the air-conditioned space generating system 1, the cooling airflow 301 is discharged upward from the upper opening 108. Here, the cooling airflow 301 discharged from the upper opening 108 flows along the wall surface 30 due to an attraction phenomenon caused by the Coanda effect (a phenomenon in which a negative pressure area is generated between the blown-out air and the wall surface 30, and the blown-out airflow is attracted to the negative pressure area). Here, the cooling airflow 301 flowing along the wall surface 30 is just one example.

[0037] Then, the cooling airflow 301 released from the upper opening 108 hits the protruding portion 22 on the interior ceiling 20. Then, the cooling airflow 301 that hits the protruding portion 22 flows along the curved surface of the extension portion 21 so as to be reflected downward.

[0038] Then, cooling airflow 301 flowing downward is emitted from tip 21a toward ground 70. Cooling airflow 301 flowing toward ground 70 flows backward along ground 70 and is sucked in from front opening 106 via front opening 103. Here, cooling airflow 301 flowing along ground 70 is just one example.

[0039] The sucked cooling airflow 301 is then released again by the air conditioner 60 as cooling airflow 301 flowing upward. In this way, a series of cooling airflows 301 are formed in the air-conditioned space.

[0040] Next, the airflow during heating in the air-conditioned space generating system 1 will be described with reference to Fig. 3. During heating operation, the air conditioner 60 draws air through the upper opening 108. The drawn air is released as heating airflow 302 from the front opening 106 and the front opening 103.

[0041] In this way, in the air-conditioned space generating system 1, the heating airflow 302 is discharged upward from the front opening 103 through the front opening 106. Here, the heating airflow 302 discharged from the front opening 103 rises upward due to buoyancy.

[0042] The heating airflow 302 discharged from the front opening 103 hits the extension 21 of the interior ceiling 20 .

[0043] The heated airflow 302 that hits the extension 21 flows rearward along the protrusion 22. The heated airflow 302 that has flowed rearward hits the wall surface 30.

[0044] Then, the heating airflow 302 that hits the wall surface 30 changes its airflow direction, flows downward along the wall surface 30, and is sucked in through the upper opening 108. Here, the heating airflow 302 that hits the extension portion 21 may be sucked in through the upper opening 108 without hitting the wall surface 30.

[0045] The drawn-in heating airflow 302 is then released again by the air conditioner 60 as a heating airflow 302 flowing forward. In this way, a series of heating airflows 302 are formed in the air-conditioned space.

[0046] Fig. 5 shows the temperature distribution in the air-conditioned space generating system 1. The darker the color in the temperature distribution, the lower the temperature, and the lighter the color in the temperature distribution, the higher the temperature.

[0047] Figure 5(a)-(b) shows the simulation results of the temperature distribution when the air-conditioning space generation system 1 shown on the yz plan view is in cooling operation and the outside wind blows from the positive side of the y-axis to the negative side of the y-axis (from the front to the rear).

[0048] 5(a) shows the results of a simulation of the temperature distribution in the air-conditioned space generating system 1 in a state where the exterior ceiling 10 is removed from the first embodiment. The color of the temperature distribution is lighter around the housing 100, indicating that the temperature around the housing 100 is approximately the same as the outside air temperature. In other words, the cooling airflow 301 flows along with the outside wind, and no air-conditioned space (cooled space) is formed around the housing 100.

[0049] 5(b) shows the air-conditioned space generating system 1 of the present embodiment 1. The color of the temperature distribution is darker surrounding the housing 100, indicating that an air-conditioned space (cooled space) is formed around the housing 100.

[0050] Example 2 In this embodiment, the same components as those in the other embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted. An outline of the air-conditioned space generating system 1 according to the second embodiment will be described with reference to Figs. 6 and 7.

[0051] In the second embodiment, as shown in FIG. 6, the air-conditioned space generating system 1 includes a retrofit wall surface 31 and a retrofit wall surface opening 32 in addition to the components of the first embodiment.

[0052] The rear-mounted wall surface 31 is a rectangular surface that is in contact with the upper surface 107 and is positioned parallel to the wall surface 30. The rear-mounted wall surface 31 is positioned to the side and forward of the upper opening 108, and forms an air passage between the rear-mounted wall surface 31 and the wall surface 30 for passing conditioned air. The rear-mounted wall surface opening 32 is an opening that is surrounded by the interior ceiling 20, the rear-mounted wall surface 31, the first side wall 40, and the second side wall 50.

[0053] Next, we will explain the airflow during cooling in the air-conditioned space generation system 1. In the air-conditioned space generation system 1, the cooling airflow 301 is discharged upward from the upper opening 108. Here, the cooling airflow 301 discharged from the upper opening 108 passes through the air path between the wall surface 30 and the retrofit wall surface 31.

[0054] Then, the cooling airflow 301 that has passed through the air passage between the wall surface 30 and the retrofit wall surface 31 hits the protruding portion 22 on the interior ceiling 20 .

[0055] Then, the cooling airflow 301 that hits the protruding portion 22 passes through the retrofitted wall opening 32, and then flows downward along the curved surface of the extension portion 21 so as to be reflected due to the induction phenomenon caused by the Coanda effect.

[0056] Then, the cooling airflow 301 flowing downward is emitted from the tip end 21a toward the ground 70. The cooling airflow 301 flowing toward the ground 70 flows backward along the ground 70 and is sucked in from the front opening 106 via the front opening 103.

[0057] The sucked cooling airflow 301 is then released again by the air conditioner 60 as cooling airflow 301 flowing upward. In this way, a series of cooling airflows 301 are formed in the air-conditioned space.

[0058] 7, the airflow during heating in the air-conditioned space generating system 1 will be described. In the air-conditioned space generating system 1, a heating airflow 302 is discharged forward from the front opening 103 via the front opening 106. Here, the heating airflow 302 discharged from the front opening 103 rises upward due to buoyancy.

[0059] The heating airflow 302 discharged from the front opening 103 hits the extension 21 of the interior ceiling 20 .

[0060] The heated airflow 302 that hits the extension 21 flows rearward along the protrusion 22. The heated airflow 302 that has flowed rearward passes through the rear-mounted wall opening 32 and hits the wall surface 30.

[0061] Then, the heating airflow 302 that hits the wall surface 30 changes its airflow direction, passes through the air passage between the wall surface 30 and the attached wall surface 31, flows downward, and is sucked in through the upper opening 108.

[0062] The drawn-in heating airflow 302 is then released again by the air conditioner 60 as a heating airflow 302 flowing forward. In this way, a series of heating airflows 302 are formed in the air-conditioned space.

[0063] Example 3 In this embodiment, the same components as those in the other embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted. Referring to Fig. 8, an overview of the air-conditioned space generating system 1 according to the third embodiment will be described.

[0064] In the third embodiment, as shown in Fig. 8, the air-conditioning space generating system 1 has a connection plate 80 between the exterior ceiling 10 and the interior ceiling 20. The exterior ceiling 10 and the interior ceiling 20 are connected to each other via the connection plate 80.

[0065] The connecting plate 80 may be connected at any location, but for example, the connecting plate 80 connects the lower surface 13 and the tip portion 21a.

[0066] A space 90 is formed between the connecting plate 80 and the wall surface 30. The space 90 is located between the outer ceiling 10 and the inner ceiling 20.

[0067] Without the connecting plate 80, part of the outside wind may enter the space 90 and affect the air-conditioning airflow (cooling airflow 301 or heating airflow 302) flowing along the interior ceiling 20.

[0068] On the other hand, in this embodiment, the presence of the connecting plate 80 can prevent outside wind from entering the space 90 (particularly the space behind the extension portion 21). This can reduce the impact on the air conditioning airflow (cooling airflow 301 or heating airflow 302) flowing along the interior ceiling 20.

[0069] In this way, the presence of the connecting plate 80 can further suppress the influence of outside wind.

[0070] Below, additional information will be provided regarding each example.

[0071] Although the housing 100 has been described as having a seat plate 101, a front surface 102, a front opening 103, a front surface 105, a front opening 106, an upper surface 107, an upper opening 108, a lower surface 109, and a rear surface 110, the seat plate 101, the front surface 102, the front opening 103, etc. are not essential because the effects of the present disclosure can be obtained even without these.

[0072] For example, if the seat plate 101, the front surface 102, and the front opening 103 were not present, air would pass between the inside and outside of the housing 100 via the front opening 106.

[0073] Furthermore, upper opening 108 need only be provided in housing 100 above front opening 106 , and does not necessarily have to be provided on top surface 107 .

[0074] Furthermore, upper opening 108 is configured to serve as an outlet for discharging cooling airflow 301 during cooling operation, but does not have to serve as an inlet for drawing in heating airflow 302 during heating operation. In this case, during heating operation, another opening may be provided in housing 100 above front opening 106, and this opening may serve as an inlet for drawing in heating airflow 302.

[0075] Furthermore, front opening 106 is configured to serve as an outlet for discharging heating airflow 302 during heating operation, but does not have to serve as an intake port for drawing in cooling airflow 301 during cooling operation. In this case, during cooling operation, another opening may be provided in housing 100 above front opening 106, and this opening may serve as an intake port for drawing in cooling airflow 301.

[0076] Moreover, the front opening 106 may be provided above the seat plate 101. In this case, the front opening 106 may serve as an air intake port that draws in the cooling airflow 301 during cooling operation.

[0077] Furthermore, although the housing 100 is in contact with the wall surface 30 via the rear surface 110, the rear surface 110 and the wall surface 30 may be considered to be one and the same surface as a single plate.

[0078] In the interior ceiling 20, the extension 21 is connected to the protrusion 22 and is provided on the downward side, but the extension 21 and the protrusion 22 may be considered as a single flat plate. In other words, the extension 21 may not be inclined downward, and the interior ceiling 20 may be a single flat plate.

[0079] Furthermore, in the interior ceiling 20, the direction of the tangent 210 of the extension 21 is inclined so that the angle of downward increases toward the front side, but the extension 21 may not be curved but may be bent at a right angle. This is because the effects of the present disclosure can be obtained even with an extension 21 bent at a right angle.

[0080] Although the tip portion 11, the first front portion 43, and the second front portion 53 are on the same plane, , may be located further forward than the first front portion 43 and the second front portion 53. This is because by making the outer ceiling 10 longer in the front-to-rear direction, it is possible to make the vehicle less susceptible to the effects of outside wind.

[0081] The air conditioner 60 includes not only an air conditioner that switches between cooling operation and heating operation, but also a cooler alone or a heater alone. In other words, the air-conditioned space generating system 1 includes a case where heating operation or cooling operation is not performed.

[0082] In the height 206 direction (upward), the length 202 between the tip 21a and the underside 13 of the tip 11 is set to be 1.2 times or more the length 200 between the protrusion 22 and the underside 13 of the tip 11. For example, the length 200 is 200 mm (0 to 700 mm or 0 to 1500 mm), and the length 202 is 400 mm (200 to 900 mm or 100 to 1600 mm). The length 202 is 200 mm (100 to 400 mm or 100 to 1600 mm) longer than the length 200.

[0083] By making length 201 from tip 21a to front end 11 longer in the front-rear direction (y-axis direction) than length 203 from wall surface 30 to tip 21a, it is possible to reduce the influence of outside wind. For example, length 201 is 650 mm (400 to 700 mm or 100 to 1200 mm), and length 203 is 600 mm (400 to 800 mm or 100 to 1200 mm).

[0084] On the other hand, it is also possible to make the device more compact by making the length 201 shorter than the length 203. For example, the length 201 may be 500 mm and the length 203 may be 750 mm.

[0085] By making the length 204 from the tip portion 11 to the front end 101a shorter than the length 205 from the front end 101a to the rear surface 110, it is possible to make it more compact. On the other hand, by making the length 204 longer than the length 205, it is possible to make it less susceptible to the influence of outside wind. For example, the length 204 is 500 mm (300 to 700 mm or 100 to 1200 mm), and the length 205 is 750 mm (500 to 800 mm or 100 to 1200 mm).

[0086] The front end 101a is located forward (on the positive y-axis direction) of the tip portion 21a. In other words, the length 205 from the front end 101a to the rear surface 110 is longer than the length 203 from the wall surface 30 to the tip portion 21a.

[0087] The length 200 is set to be one-fifth or less of the height 206 from the ground 70 to the underside 13. This is because a shorter length 200 makes it less susceptible to the effects of outside wind. For example, the height 206 is 2000 mm (1800 to 2200 mm, 1800 to 3000 mm, or 1600 to 3500 mm).

[0088] Next, the effects of the present disclosure will be described.

[0089] The following items are independent of the scope of the claims. Although specific descriptions may be provided, they are merely examples and do not limit the scope of the claims.

[0090] (Item 1) An air-conditioning space generating system 1 having a housing 100, an air conditioner 60, a first side wall 40, a second side wall 50, a wall surface 30, an inner ceiling 20, and an outer ceiling 10, The housing 100 is disposed between the first side wall 40 and the second side wall 50 and includes a front surface 105, an upper surface 107, a rear surface 110, and a lower surface 109. The front surface 105 has a front surface opening 106; The housing 100 has an upper opening 108 above the front opening 106, The air conditioner 60 is installed in the housing 100 and performs cooling operation. The wall surface 30 is connected to the rear surface 110, The interior ceiling 20 includes a protrusion 22 and an extension 21. The protrusion 22 protrudes forward from the wall surface 30, The extension 21 is connected to the protrusion 22, The outer ceiling 10 is provided above the inner ceiling 20 and is connected to the wall surface 30. The most forward part of the outer ceiling 10 is the front part 11, The forward-most portion of the first side wall 40 is a first front portion 43, The most forward portion of the second side wall 50 is a second front portion 53, If the most distal end portion of the extension portion 21 is defined as a distal end portion 21a, The tip portion 11, the first front portion 43, and the second front portion 53 are located forward of the tip portion 21a, When the air conditioner 60 performs cooling operation, The upper opening 108 allows air to rise, The inner ceiling 20 directs the air rising from the upper opening 108 forward, The front opening 106 may be configured to draw in air that has descended forward through the interior ceiling 20.

[0091] According to this configuration, when the air conditioner 60 performs cooling operation, the cooling airflow 301 emitted from the tip 21a toward the ground 70 functions as an air curtain. This suppresses the flow of air between the inside and outside of the air-conditioned space. At this time, if there is no wind outside the air-conditioned space, the first side wall 40 and the second side wall 50 sufficiently suppress the inflow of air into the air-conditioned space generation system 1 or the outflow of air to the outside of the air-conditioned space generation system 1. Furthermore, even if there is wind outside the air-conditioned space (if there is outside wind), the presence of the exterior ceiling 10 in addition to the first side wall 40 and the second side wall 50 prevents the cooling airflow 301 from being disturbed by the outside wind. This allows the cooling airflow 301 to be contained within the air-conditioned space generation system, and the cooling airflow 301 can generate an air-conditioned space within the air-conditioned space generation system 1.

[0092] (Item 2) An air-conditioning space generating system 1 having a housing 100, an air conditioner 60, a first side wall 40, a second side wall 50, a wall surface 30, an inner ceiling 20, and an outer ceiling 10, The housing 100 is disposed between the first side wall 40 and the second side wall 50 and includes a front surface 105, an upper surface 107, a rear surface 110, and a lower surface 109. The front surface 105 has a front surface opening 106; The housing 100 has an upper opening 108 above the front opening 106, The air conditioner 60 is installed in the housing 100 and performs heating operation. The wall surface 30 is connected to the rear surface 110, The interior ceiling 20 includes a protrusion 22 and an extension 21. The protrusion 22 protrudes forward from the wall surface 30, The extension 21 is connected to the protrusion 22, The outer ceiling 10 is provided above the inner ceiling 20 and is connected to the wall surface 30. The most forward part of the outer ceiling 10 is the front part 11, The forward-most portion of the first side wall 40 is a first front portion 43, The most forward portion of the second side wall 50 is a second front portion 53, If the most distal end portion of the extension portion 21 is defined as a distal end portion 21a, The tip portion 11, the first front portion 43, and the second front portion 53 are located forward of the tip portion 21a, When the air conditioner 60 performs heating operation, The front opening 106 allows air to escape forward, The inner ceiling 20 is extended forward from the front opening 106 and then rises toward the wall surface 30. Let the air descend, The upper opening 108 may be configured to draw in air that is drawn down by the interior ceiling 20 .

[0093] According to this configuration, when the air conditioner 60 performs heating operation, the heating airflow 302 discharged from the front opening 103 toward the tip end 21a of the air-conditioned space generating system 1 functions as an air curtain. This suppresses airflow between the inside and outside of the air-conditioned space. In this case, if there is no wind outside the air-conditioned space, the first side wall 40 and the second side wall 50 sufficiently suppress air from flowing into the air-conditioned space generating system 1 or air from flowing out of the air-conditioned space generating system 1. Furthermore, even if there is wind outside the air-conditioned space (external wind), the presence of the exterior ceiling 10 in addition to the first side wall 40 and the second side wall 50 prevents the heating airflow 302 from being disturbed by the external wind. This allows the heating airflow 302 to be contained within the air-conditioned space generating system, and the heating airflow 302 can generate a heated space within the air-conditioned space generating system 1.

[0094] (Item 3) The extension 21 may be configured to face downward.

[0095] According to this configuration, the cooling airflow 301 that collides with the protrusion 22 can be effectively directed downward. This makes it possible to suppress the expansion of the cooling airflow 301, so that the cooling airflow 301 is less likely to be disturbed by outside wind. This makes it possible to more effectively keep the cooling airflow 301 within the air-conditioned space generating system 1.

[0096] Furthermore, with this configuration, the heating airflow 302 that rises toward the wall surface 30 can be smoothly guided to the protruding portion 22. This prevents the heating airflow 302 from spreading, making it less likely to be disturbed by outside wind. This allows the heating airflow 302 to be more effectively contained within the air-conditioned space generating system 1.

[0097] (Item 4) In a cross section (yz cross section) perpendicular to the direction from the first side wall 40 to the second side wall 50 (+x direction), the direction of the tangent 210 in the extension portion 21 may be configured to be inclined so that the angle pointing downward (-z direction) increases as it moves forward (+y direction).

[0098] According to this configuration, the cooling airflow 301 that collides with the protrusion 22 can be directed downward more effectively.

[0099] Furthermore, with this configuration, the heating airflow 302 rising toward the wall surface 30 can be guided to the protruding portion 22 more effectively.

[0100] (Item 5) In a cross section (yz cross section) perpendicular to the direction from the first side wall 40 to the second side wall 50 (+x direction), the direction of the tangent 210 in the extension portion 21 may be configured to be roughly parallel to the vertical direction (z direction) near the tip portion 21a, or to be inclined so as to narrow inward (-y direction) as it goes downward (-z direction).

[0101] According to this configuration, the cooling airflow 301 that collides with the protrusion 22 can be directed downward more effectively.

[0102] Furthermore, with this configuration, the heating airflow 302 rising toward the wall surface 30 can be guided to the protruding portion 22 more effectively.

[0103] (Item 6) In the height 206 direction (+z direction), the length 202 between the tip 21a and the underside 13 of the tip 11 may be configured to be 1.2 times or more the length 200 between the protrusion 22 and the underside 13 of the tip 11.

[0104] With this configuration, the length 202 can be made sufficiently longer than the length 200. This makes it difficult for outside wind that has passed under the exterior ceiling 10 to enter the air-conditioned space generation system 1. This makes it possible to more effectively retain the conditioned air (air conditioned by the cooling airflow 301 or the heating airflow 302) within the air-conditioned space generation system 1.

[0105] (Item 7) In the forward direction (+y direction), a length 201 from the tip 21a to the tip portion 11 may be longer than a length 203 from the wall surface 30 to the tip 21a.

[0106] According to this configuration, the length of the exterior ceiling 10 in the front-to-rear direction (length 201+length 203) can be made sufficiently longer than the length 203. This makes it difficult for outside wind to enter the air-conditioned space generating system 1, so that the conditioned air (air conditioned by the cooling airflow 301 or the heating airflow 302) can be more effectively retained within the air-conditioned space generating system 1.

[0107] (Item 8) The housing 100 includes a seat plate 101, The seat plate 101 is connected to the front surface 105, The front opening 106 is located below the seat plate 101. If the most forward portion of the seat panel 101 is defined as a front end 101a, The front end 101a may be configured to be located forward (in the +y direction) of the tip portion 21a.

[0108] According to this configuration, the housing 100 has the shape of a chair on which a user can sit, and the user can sit on the seat plate 101. Therefore, it is possible to more locally air-condition the area around the user seated on the seat plate 101. In addition, when a user sits on the housing, it is possible to make it less likely that the user's head will hit the inner ceiling 20 when sitting down or leaving the seat.

[0109] (Item 9) The front surface 105 may be configured to be located rearward (in the -y direction) from the tip portion 21a.

[0110] This configuration allows for more localized air conditioning around the user seated on the seat plate 101. This localized air conditioning can particularly provide conditioned air (air conditioned by the cooling airflow 301 or the heating airflow 302) that satisfies the condition of a cool head and warm feet.

[0111] (Item 10) A connection plate 80 that connects the extension portion 21 and the outer ceiling 10 may be provided.

[0112] This configuration can further reduce the influence of outside wind.

As long as it does not deviate from the spirit of the present disclosure, various modifications conceivable by a person skilled in the art to the examples and configurations constructed by combining components of different examples are also included within the scope of the present disclosure.
