[Diagram 5] FIG. 11 is a diagram showing a configuration of a ventilation system according to a fifth embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Example 1 The examples described below each show a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, the arrangement and connection of the components, as well as the steps (processes) and the order of the steps shown in the following examples are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following examples, those components that are not described in the independent claims showing the highest concept of the present disclosure are described as optional components. In addition, in each figure, the same reference numerals are given to substantially the same configurations, and duplicated descriptions are omitted or simplified.

[0011] Figures 1(a)-(d) show the configuration of an air blowing system 1000. Figure 1(a) is an upper perspective view of the toilet room 10, Figure 1(b) is a lower perspective view of the toilet room 10, and Figure 1(c) is a side view of the toilet room 10. A floor surface 20 is arranged below the toilet room 10, a wall surface 22 is arranged on one side of the toilet room 10, and a ceiling surface 24 is arranged above the toilet room 10. In this way, the toilet room 10 is a space surrounded by the floor surface 20, the wall surface 22, and the ceiling surface 24.

[0012] A lining 100 is installed along a wall surface 22 of the toilet room 10. The lining 100 has a box-shaped hollow structure formed by combining the wall surface 22 and the floor surface 20. The lining 100 includes a front side surface 110 provided in front of the wall surface 22 and parallel to the wall surface 22, and an upper side surface 120 provided above the floor surface 20 and parallel to the floor surface 20. The front side surface 110 and the upper side surface 120 are connected to each other at a right angle at a corner of the front upper part of the lining 100.

[0013] A plurality of toilet bowls 200 are installed on the front side surface 110 of the lining 100. The toilet bowls 200 are, for example, urinals, but may also be toilet bowls. Therefore, the lining 100 is provided with a support mechanism for supporting the plurality of toilet bowls 200. In addition, water supply pipes and drain pipes connected to each of the toilet bowls 200 are stored inside the lining 100.

[0014] FIG. 1(d) shows a cross-sectional view of the lining 100 from the same direction as FIG. 1(c). The lining 100 has a hollow space 102 surrounded by a floor surface 20, a wall surface 22, a front side surface 110, and an upper side surface 120. The hollow space 102 corresponds to the inside of the lining 100. An intake port 150 penetrating between the toilet room 10 and the hollow space 102 is arranged on the lower side of the front side surface 110. In addition, a conveying fan 152 is arranged on the upper side of the conveying fan 152 in the hollow space 102. Furthermore, a slit-shaped air outlet 154 extending along the wall surface 22 is arranged on the wall surface 22 side of the upper side surface 120. The air outlet 154 also penetrates between the toilet room 10 and the hollow space 102. Return to FIG. 1(a)-(c).

[0015] An exhaust duct 300 extending to the outside is arranged in the attic 12 of the toilet room 10. The exhaust duct 300 is connected to a ventilation device 302 installed in the attic 12 of the toilet room 10. A lower part of the ventilation device 302 is connected to a ceiling duct 304 installed on the ceiling surface 24. The ceiling duct 304 extends from the ceiling surface 24 toward the wall surface 22. An end of the ceiling duct 304 on the wall surface 22 side is connected to a wall duct 306. The wall duct 306 extends along the wall surface 22. This corresponds to extending in the direction in which the air outlet 154 extends. A slit-shaped ventilation opening 310 is arranged in the lower part of the wall duct 306. Such a ventilation opening 310 can be said to be installed on the ceiling surface 24.

[0016] The exhaust duct 300, the ventilation device 302, the ceiling duct 304, and the wall duct 306 all have a hollow structure, and these hollow spaces are connected to the toilet room 10 via the ventilation opening 310. When the distance between the ventilation opening 310 and the wall surface 22 is called the "first distance," the distance between the part of the toilet bowl 200 farthest from the wall surface 22 and the wall surface 22 is called the "second distance." The first distance is shorter than the second distance.

[0017] As the transport fan 152 of the lining 100 rotates, air in the toilet room 10 is drawn into the inside of the lining 100 through the suction port 150. Also, as the transport fan 152 rotates, the air drawn into the inside of the lining 100 is blown out through the blow-out port 154 and rises along the wall surface 22. Furthermore, as the ventilation device 302 rotates, the air that has risen along the wall surface 22 is drawn into the ventilation port 310 and is discharged to the outside via the wall surface duct 306, the ceiling surface duct 304, and the exhaust duct 300.

[0018] In the above configuration, the air inlet 150, the transport fan 152, the air outlet 154, and the ventilation port 310 are included in the air blowing system 1000. The ceiling duct 304 and the wall duct 306 may also be included in the air blowing system 1000.

[0019] According to this embodiment, air is sucked in through the intake port 150 arranged on the front side surface 110 of the lining 100, and is blown out from the outlet port 154 arranged on the upper side surface 120 of the lining 100 so that the air rises along the wall surface 22 and is sucked into the ventilation port 310, so that the air in the toilet room 10 can be efficiently exhausted to the outside while suppressing the complexity of the configuration. Also, the outlet port 154 has a slit shape, and the ventilation port 310 has a slit shape extending in the direction in which the outlet port 154 extends, so that the air blown out from the outlet port 154 can be efficiently sucked into the ventilation port 310.

[0020] An outline of one aspect of the present disclosure is as follows. (Item 1) A lining (100) is installed along a wall surface (22) of a toilet room (10), and an inlet (150) is arranged on a front side surface (110) of the lining (100) on the front side of which a toilet bowl (200) is installed; a conveying fan (152) disposed inside the lining (100); an air outlet (154) disposed on the upper surface (120) of the lining (100); As the transport fan (152) rotates, air in the toilet room (10) is sucked into the inside of the lining (100) through the suction port (150), As the transport fan (152) rotates, air sucked into the inside of the lining (100) is blown out from the air outlet (154), rises along the wall surface (22), and is sucked into a ventilation opening (310) installed on the ceiling surface (24) of the toilet room (10).

[0021] (Item 2) The air outlet (154) has a slit shape extending along the wall surface (22), The ventilation opening (310) has a slit shape extending in the extension direction of the air outlet (154), Item 1. The air blowing system (1000) according to item 1, wherein a first distance between the ventilation opening (310) and the wall surface (22) is shorter than a second distance between the wall surface (22) and a portion of the toilet (200) farthest from the wall surface (22).

[0022] Example 2 Next, a description will be given of Example 2. Example 2 has a similar air blowing system 1000 to Example 1, but differs from Example 1 in the configuration of the ventilation opening 310. The following description will focus on the differences from Example 1.

[0023] 2(a)-(b) show the configuration of the air blowing system 1000. Fig. 2(a) is a bottom perspective view of the toilet room 10, and Fig. 2(b) is a side view of the toilet room 10, which are shown in the same manner as Fig. 1(b) and Fig. 1(c), respectively. The lining 100, the exhaust duct 300, and the ventilation device 302 in the second embodiment have the same configuration as those in the first embodiment.

[0024] The lower part of the ventilation device 302 is connected to a ceiling duct 304 installed on the ceiling surface 24. The ceiling duct 304 protrudes downward from the ceiling surface 24 and extends in the direction in which the air outlet 154 extends. A slit-shaped ventilation opening 310 is arranged in the lower part of the ceiling duct 304. As described above, when the distance between the ventilation opening 310 and the wall surface 22 is called the "first distance," the distance between the part of the toilet 200 farthest from the wall surface 22 and the wall surface 22 is called the "second distance." The first distance is longer than the second distance. With this configuration, the air that rises from the air outlet 154 along the wall surface 22 flows along the ceiling surface 24 toward the ceiling duct 304 and is then sucked into the ventilation opening 310.

[0025] In the above configuration, the air inlet 150, the transport fan 152, the air outlet 154, and the ventilation opening 310 are included in the air blowing system 1000. The ceiling surface duct 304 may also be included in the air blowing system 1000.

[0026] According to this embodiment, the ceiling surface duct 304 protrudes downward from the ceiling surface 24, and the ventilation opening 310 is disposed in the lower part of the ceiling surface duct 304 extending in the direction in which the air outlet 154 extends, so that the air blown out from the air outlet 154 can be efficiently sucked into the ventilation opening 310.

[0027] An outline of one aspect of the present disclosure is as follows. (Item 3) The air outlet (154) has a slit shape extending along the wall surface (22), a first distance between the ventilation opening (310) and the wall surface (22) is longer than a second distance between the wall surface (22) and a portion of the toilet bowl (200) farthest from the wall surface (22); The ventilation opening (310) is a ceiling surface duct (304) protruding downward from the ceiling surface (24), and is positioned in a lower portion of the ceiling surface duct (304) extending in the direction in which the air outlet (154) extends.

[0028] Example 3 Next, a third embodiment will be described. The third embodiment is an air blowing system 1000 similar to the previous ones, but differs from the previous ones in the configuration of the ventilation opening 310. The following description will focus on the differences from the previous ones.

[0029] Figures 3(a)-(b) show the configuration of the air blowing system 1000. Figure 3(a) is a bottom perspective view of the toilet room 10, and Figure 3(b) is a side view of the toilet room 10, which are shown in the same manner as Figures 1(b) and 1(c), respectively. The lining 100, the exhaust duct 300, and the ventilation device 302 in the third embodiment have the same configuration as those in the first embodiment.

[0030] The lower part of the ventilation device 302 opens on the ceiling surface 24, and the opened part is the ventilation port 310. Therefore, in the third embodiment, the ceiling surface duct 304 and the wall surface duct 306 are not installed as in the past. Also, on the ceiling surface 24, a prevention wall 320 is installed at a position farther from the wall surface 22 than the ventilation port 310. The prevention wall 320 has a shape that protrudes downward from the ceiling surface 24, and extends in the direction in which the air outlet 154 extends. With this configuration, the air that rises from the air outlet 154 along the wall surface 22 moves away from the wall surface 22 along the ceiling surface 24. A part of such air is sucked into the ventilation port 310, but the rest moves away from the wall surface 22 from the ventilation port 310. The air that moves away from the wall surface 22 is reflected by the prevention wall 320 and returns toward the ventilation port 310.

[0031] In the above configuration, the air inlet 150, the transport fan 152, the air outlet 154, and the ventilation port 310 are included in the air blowing system 1000. The prevention wall 320 may be included in the air blowing system 1000.

[0032] According to this embodiment, a prevention wall 320 is installed at a position farther from the wall surface 22 than the ventilation opening 310, protruding downward from the ceiling surface 24 and extending in the direction in which the air outlet 154 extends, so that the air blown out from the air outlet 154 can be efficiently sucked into the ventilation opening 310.

[0033] An outline of one aspect of the present disclosure is as follows. (Item 4) The apparatus further includes a prevention wall (320) protruding downward from the ceiling surface (24), The air outlet (154) has a slit shape extending along the wall surface (22), The prevention wall (320) extends in the extension direction of the air outlet (154), 2. The ventilation system (1000) according to item 1, wherein the prevention wall (320) is disposed farther from the wall surface (22) than the ventilation opening (310).

[0034] Example 4 Next, a fourth embodiment will be described. The fourth embodiment is an air blowing system 1000 similar to the previous ones, but differs from the previous ones in the configuration of the air outlet 154 and the ventilation opening 310. The following description will focus on the differences from the previous ones.

[0035] Figures 4(a)-(b) show the configuration of the air blowing system 1000. Figure 4(a) is an upper perspective view of the toilet room 10, and Figure 4(b) is a lower perspective view of the toilet room 10, which are shown in the same manner as Figures 1(a) and 1(b), respectively. The exhaust duct 300 and the ventilation device 302 in the fourth embodiment have the same configuration as those in the first embodiment.

[0036] The lower part of the ventilation device 302 opens in the ceiling surface 24 as in the third embodiment, and the opened part is the ventilation opening 310. Moreover, the length of the air outlet 154 in the lining 100 in the direction in which it extends along the wall surface 22 is shorter than the length of the air outlet 154 in the same direction in the first embodiment. For example, the length of the air outlet 154 is approximately the same as the ventilation opening 310 in the same direction.

[0037] On the ceiling surface 24, the first prevention wall 320a and the second prevention wall 320b extend in a direction different from the direction along the wall surface 22, for example, in a direction perpendicular to the direction along the wall surface 22. For example, the first prevention wall 320a and the second prevention wall 320b extend from the wall surface 22 to the ventilation opening 310. The first prevention wall 320a and the second prevention wall 320b are installed on either side of the ventilation opening 310 in the direction along the wall surface 22. The distance between the first prevention wall 320a and the second prevention wall 320b is set to be equal to or greater than the length of the air outlet 154 in the direction extending along the wall surface 22. Furthermore, the first prevention wall 320a and the second prevention wall 320b have a shape that protrudes downward from the ceiling surface 24. With this configuration, the air that rises from the air outlet 154 along the wall surface 22 moves away from the wall surface 22 along the ceiling surface 24 and is sucked into the ventilation opening 310. At this time, the air is prevented from diffusing in the direction along the wall surface 22 by the first prevention wall 320a and the second prevention wall 320b.

[0038] In the above configuration, the air inlet 150, the transport fan 152, the air outlet 154, and the ventilation port 310 are included in the air blowing system 1000. The air blowing system 1000 may also include a first prevention wall 320a and a second prevention wall 320b.

[0039] According to this embodiment, the first prevention wall 320a and the second prevention wall 320b are installed on either side of the ventilation opening 310 in the direction along the wall surface 22, so that the air blown out from the air outlet 154 can be efficiently sucked into the ventilation opening 310.

[0040] An outline of one aspect of the present disclosure is as follows. (Item 5) The device further includes a first prevention wall (320) and a second prevention wall (320) protruding downward from the ceiling surface (24), The first prevention wall (320) and the second prevention wall (320) extend in a direction different from a direction along the wall surface (22), Item 2. The ventilation system (1000) according to item 1, wherein the first prevention wall (320) and the second prevention wall (320) are installed on either side of the ventilation opening (310) in a direction along the wall surface (22).

[0041] Example 5 Next, a fifth embodiment will be described. The fifth embodiment is an air blowing system 1000 similar to the previous ones, but differs from the previous ones in the configuration of the air inlet 150. The following description will focus on the differences from the previous ones.

[0042] Fig. 5 is a perspective view showing the configuration of the air blowing system 1000. The air inlet 150 up to now has been disposed on the lower side of the front side surface 110. On the other hand, as shown in Fig. 5, the air inlet 150 according to the fifth embodiment is disposed in a portion other than the lower side of the front side surface 110. The air inlet 150 may be disposed below the transport fan 152 (not shown).

[0043] According to this embodiment, the front side surface 110 is also disposed in a portion other than the lower side of the front side surface 110, so that the degree of freedom in the configuration can be improved.

[0044] The present disclosure has been described above based on the embodiments. These embodiments are merely illustrative, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each treatment process, and that such modifications are also within the scope of the present disclosure.
