Description

[Technical field]

[0001] The present invention relates to an outdoor hood. [Background technology]

[0002] Conventionally, this type of outdoor hood is known to be provided at the outdoor end of a duct for transporting air from indoors to outdoors. Patent Document 1 discloses an outdoor hood of this type that controls the direction of the airflow blown out from the outdoor hood so that the airflow is directed away from the exterior wall of the building.

[0003] The outdoor hood will be described below with reference to FIG.

[0004] As shown in FIG. 11, the outdoor hood 900, which is installed on an exterior wall not shown, is roughly box-shaped and has a hood front surface 810, a hood right side surface 820, a hood left side surface 830, a hood top surface 840, and a hood bottom surface 850.

[0005] The hood front surface 810 is a plate member that is arranged in a position facing the outer wall in an inner circumferential space formed by the outdoor hood 900 and the outer wall.

[0006] Hood right side surface 820 is a plate member that stands up toward the outer wall from the right end portion of hood front surface 810. Hood right side surface 820 includes ventilation opening 821 and fins 822.

[0007] The ventilation opening 821 is an opening for blowing out air that has been transported from inside to outside.

[0008] Fin 822 is a flat plate standing from the upper end to the lower end of ventilation hole 821. One end of fin 822 not in contact with ventilation hole 821 is inclined toward the inner periphery space of outdoor hood 900, and the other end not in contact with ventilation hole 821 is inclined toward the outer periphery space of outdoor hood 900. A plurality of fins 822 are arranged in ventilation hole 821.

[0009] Hood left side surface 830 is a plate member that stands toward the outer wall from the left end portion of hood front surface 810. Hood left side surface 830 includes ventilation opening 831 and fins 832.

[0010] The ventilation opening 831 is an opening for blowing out air that has been transported from inside to outside.

[0011] The fins 832 are flat plates that stand up from the upper end to the lower end of the ventilation hole 831. One end of the fins 832 that is not in contact with the ventilation hole 831 is inclined toward the inner periphery space of the outdoor hood 900, and the other end that is not in contact with the ventilation hole 831 is inclined toward the outer periphery space of the outdoor hood 900. A plurality of fins 832 are arranged in the ventilation hole 831.

[0012] Hood upper surface 840 is a plate member that covers the upper opening of the opening formed by the outer wall, hood front surface 810, hood right side surface 820, and hood left side surface 830.

[0013] Hood bottom surface 850 is a plate member that covers the lower opening of the opening formed by the outer wall, hood front surface 810, hood right side surface 820, and hood left side surface 830.

[0014] With this configuration, the direction of the airflow of the air blown out from the ventilation openings 821, 831 is controlled by the fins 822, 832. The airflow controlled by the fins 822, 832 moves in a direction away from the outer wall. This makes it possible to reduce the amount of air that comes into contact with the outer wall out of the air blown out from the ventilation openings 821, 831. This makes it possible to reduce the possibility that the outer wall will become dirty due to dust, oil, and the like contained in the air blown out from the ventilation openings 821, 831.

[0023] (Configuration of outdoor hood 100 according to embodiment 1) The configuration of an outdoor hood 100 according to a first embodiment of the present invention will be described with reference to Figs. 1 to 3.

[0024] Fig. 1 is an external perspective view showing the configuration of an outdoor hood 100 according to a first embodiment of the present invention. Fig. 2(a) is an XX cross-sectional view showing the angle between the rising direction of the first flow straightening plate and the surface having the ventilation holes in Fig. 1, and the angle between the rising direction of the second flow straightening plate and the surface having the ventilation holes in Fig. 1. Fig. 2(b) is a YY cross-sectional view showing the angle between the rising direction of the first flow straightening plate and the surface having the ventilation holes in Fig. 1, and the angle between the rising direction of the second flow straightening plate and the surface having the ventilation holes in Fig. 1. Fig. 3 is a side cross-sectional view cut at the center plane between the hood right side plate and the hood left side plate, showing the configuration of the outdoor hood 100 in Fig. 1.

[0025] The outdoor hood 100 is a type of exterior duct component that is disposed at the end of a ventilation duct (not shown) that connects the indoors and outdoors, and prevents wind, rain, and foreign objects from entering the indoors through the ventilation duct. The outdoor hood 100 is installed on the outdoor side wall surface of an exterior wall 300 that has a ventilation opening 301 for passing the ventilation duct. In FIG. 1, the exterior wall 300 is shown with dashed lines excluding the ventilation opening 301 to show that a portion of it has been cut out.

[0026] The outdoor hood 100 includes a hood front panel 10, a hood right side panel 20, a hood left side panel 30, a hood top panel 40, a hood bottom panel 50, ventilation holes 60, and a straightening section 70.

[0027] Hood front panel 10 is a rectangular plate material arranged in parallel to outer wall 300. In the first embodiment of the present invention, the rectangular shape includes a square shape.

[0028] The hood right side panel 20 is a plate member that stands vertically from the right end of the hood front panel 10 toward the outer wall 300.

[0029] The hood left side panel 30 is a plate member that stands vertically from the left end of the hood front panel 10 toward the outer wall 300.

[0030] The hood upper panel 40 is a plate member that stands vertically from the upper end of the hood front panel 10 to the outer wall 300.

[0031] The hood bottom plate 50 is a plate member that stands up from the lower end of the hood front plate 10 toward the outer wall 300.

[0032] The ends of the hood right side panel 20, the hood left side panel 30, the hood top panel 40, and the hood bottom panel 50 on the side opposite the hood front panel 10 abut against the exterior wall 300. Depending on the installation of the outdoor hood 100, a small gap may be provided between the outdoor hood 100 and the exterior wall 300.

[0033] The ventilation holes 60 are rectangular openings for passing air through at least one of the hood right side plate 20, the hood left side plate 30, the hood top plate 40, and the hood bottom plate 50. In the first embodiment of the present invention, the ventilation holes 60 are provided in the hood right side plate 20, the hood left side plate 30, and the hood bottom plate 50. The ventilation holes 60 provided in the hood right side plate 20 and the ventilation holes 60 provided in the hood left side plate 30 are arranged so as to be approximately symmetrical with respect to the center plane between the hood right side plate 20 and the hood left side plate 30. In the hood bottom plate 50, the two ventilation holes 60 arranged on the side closer to the hood right side plate 20 and the two ventilation holes 60 arranged on the side closer to the hood left side plate 30 are arranged so as to be approximately symmetrical with respect to the center plane between the hood right side plate 20 and the hood left side plate 30.

[0034] The rectifying section 70 controls the direction of air flow passing through the ventilation hole 60. In the first embodiment of the present invention, the rectifying section 70 is provided on the hood right side plate 20, the hood left side plate 30, and the hood bottom plate 50. The rectifying section 70 provided on the hood right side plate 20 and the rectifying section 70 provided on the hood left side plate 30 are arranged so as to be substantially symmetrical with respect to the center plane between the hood right side plate 20 and the hood left side plate 30. On the hood bottom plate 50, the two rectifying sections 70 arranged on the side closer to the hood right side plate 20 and the two rectifying sections 70 arranged on the side closer to the hood left side plate 30 are arranged so as to be substantially symmetrical with respect to the center plane between the hood right side plate 20 and the hood left side plate 30. The rectifying section 70 includes a first rectifying plate 71 and a second rectifying plate 72.

[0035] The first straightening plate 71 is a flat plate that stands up toward the outer wall 300 in an inner circumferential space formed by the outer wall 300 and the outdoor hood 100. The first straightening plate 71 is formed so that an angle (first angle) on the outer wall 300 side formed by the face plates (hood right side plate 20, hood left side plate 30, hood bottom plate 50) having the ventilation holes 60 and the first straightening plate 71 is smaller than 90 degrees, and preferably 45 degrees.

[0036] The second flow straightening plate 72 is provided at a position farther from the outer wall 300 than the first flow straightening plate 71, and is a flat plate that stands toward the outer wall 300 in an inner circumferential space formed by the outer wall 300 and the outdoor hood 100. The second flow straightening plate 72 is formed so that an angle (second angle) on the outer wall 300 side formed by the face plates (hood right side plate 20, hood left side plate 30, hood bottom plate 50) having the ventilation holes 60 and the second flow straightening plate 72 is larger than the first angle and smaller than 90 degrees, and is preferably 60 degrees.

[0037] The outdoor hood 100 has the above configuration.

[0038] (Features of Outdoor Food 100) Next, the features of the outdoor hood 100 according to the first embodiment will be described taking as an example a case in which air transported from an indoor space is blown out from the outdoor hood 100.

[0039] Air conveyed from an indoor space by a blower or the like (not shown) is sent to the outdoor hood 100 through a ventilation duct (not shown), and is blown out to an outdoor space through the ventilation holes 60 provided in the outdoor hood 100. The direction of the airflow of the air passing through the ventilation holes 60 is controlled by the straightening section 70. The first straightening plate 71 and the second straightening plate 72 control the airflow in a direction away from the exterior wall 300 depending on the rising direction and angle. Therefore, the amount of air blown out from the ventilation holes 60 toward the exterior wall 300 can be reduced, so that the amount of dust, oil, and the like contained in the air blown out from the ventilation holes 60 that adheres to the exterior wall 300 can be reduced. This is expected to have the effect of suppressing dirt on the exterior wall 300.

[0040] Moreover, the first angle is an acute angle compared to the second angle. Therefore, the air (first airflow) whose direction is controlled by the first straightening plate 71 is blown out in a direction farther away from the exterior wall 300 than the air (second airflow) whose direction (vector) is controlled by the second straightening plate 72. At the same time, the first airflow merges with the direction (vector) of the second airflow to become a third airflow having a vector between the first airflow and the second airflow. Therefore, the amount of air in the second airflow that tends to approach the exterior wall 300 is reduced. This is expected to have the effect of suppressing dirt on the exterior wall 300.

[0041] Furthermore, by making the second angle an obtuse angle compared to the first angle, the amount of air whose airflow direction is controlled by the second airflow straightening plate 72 is greater than the amount of air whose airflow direction is controlled by the first airflow straightening plate 71. Therefore, an increase in pressure loss caused by the airflow straightening section 70 is suppressed compared to when the second angle is the same as or smaller than the first angle. This makes it possible to obtain an outdoor hood 100 that suppresses dirt on the exterior wall 300 while suppressing a decrease in ventilation volume caused by pressure loss.

[0042] [Variations] A modified example of the first embodiment will be described below with reference to Fig. 4. In the drawings and description of the modified example, the same components and members as those in the embodiment will be given the same reference numerals. Explanations that overlap with the embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from the embodiment.

[0043] Fig. 4(a) is a XX cross-sectional view showing a modified example of the first current stabilizing plate 71 and the second current stabilizing plate 72 in Fig. 1. Fig. 4(b) is a YY cross-sectional view showing a modified example of the first current stabilizing plate 71 and the second current stabilizing plate 72 in Fig. 1.

[0044] In the description of the first embodiment, the first straightening plate 71 is a flat plate that stands toward the outer wall 300 and in the inner circumferential space formed by the outer wall 300 and the outdoor hood 100, but it may be provided with a standing portion 71c that stands from the standing tip approximately parallel to the outer wall 300. The height of the standing portion 71c is preferably about 5 mm. By providing the standing portion 71c, the airflow straightening effect of the first straightening plate 71 can be improved, and the distance between the direction of the airflow blown out from the ventilation hole 60 and the outer wall can be increased. This can be expected to further reduce dirt on the outer wall 300.

[0045] In the description of the first embodiment, the second straightening plate 72 is a flat plate that stands toward the outer wall 300 and in the inner circumferential space formed by the outer wall 300 and the outdoor hood 100, but it may be provided with a standing portion 72c that stands from the standing tip approximately parallel to the outer wall 300. The height of the standing portion 72c is preferably about 5 mm. By providing the standing portion 72c, the airflow straightening effect of the second straightening plate 72 can be improved, and the distance between the direction of the airflow blown out from the ventilation hole 60 and the outer wall can be increased. This can be expected to further reduce dirt on the outer wall 300.

[0046] The outdoor hood 100 may be provided with a third flow straightening plate between the first flow straightening plate 71 and the second flow straightening plate 72, which controls the airflow of air passing through the ventilation holes 60. The third flow straightening plate is a flat plate that stands toward the outer wall 300 in an inner circumferential space formed by the outer wall 300 and the outdoor hood 100. The third flow straightening plate has an angle (third angle) on the outer wall 300 side formed by the face plates (hood right side plate 20, hood left side plate 30, hood bottom plate 50) having the ventilation holes 60 and the third flow straightening plate, which is the same as the second angle. The third flow straightening plate has the same effect as the second flow straightening plate 72.

[0047] (Configuration of outdoor hood 100a according to embodiment 2) The configuration of an outdoor hood 100a according to a second embodiment of the present invention will be described with reference to Fig. 5 and Fig. 6. In Fig. 5 and Fig. 6, the same components as those in Fig. 1 to Fig. 4 are given the same reference numerals, and detailed description thereof will be omitted.

[0048] Fig. 5 is an external perspective view showing the configuration of an outdoor hood 100a according to embodiment 2. Fig. 6 is a side cross-sectional view taken along the center plane between the hood right side plate 20 and the hood left side plate 30, showing the configuration of the outdoor hood 100a in Fig. 5.

[0049] The outdoor hood 100a differs from the outdoor hood 100 in that it includes a wind direction adjusting plate 80 and an airflow straightening section 70a, but has the same other features as the outdoor hood 100.

[0050] The airflow direction adjustment plate 80 adjusts the flow of air transported toward the hood front panel 10. The airflow direction adjustment plate 80 is provided on the hood top panel 40, and is detachable from the outdoor hood 100a together with the hood top panel 40 in the direction of the arrow. The airflow direction adjustment plate 80 includes a first inclined plate 81, a second inclined plate 82, and a third inclined plate 83.

[0051] The first inclined plate 81 is a trapezoidal flat plate that stands vertically downward from the hood upper plate 40 and is composed of an upper base 81a and a lower base 81b that is longer than the upper base 81a.

[0052] The second inclined plate 82 is a flat plate having a shape that is line-symmetrical with respect to the upper base 81a of the first inclined plate 81 as a base axis.

[0053] The third inclined plate 83 is a triangular flat plate having a leg 81c that pairs with the leg of the first inclined plate 81 on the hood top plate 40 side, and a leg 82c that pairs with the leg of the second inclined plate 82 on the hood top plate 40 side.

[0054] The flow straightening portion 70a includes a first flow straightening plate 71 and a second flow straightening plate 72a.

[0055] The second rectifying plate 72a is provided on the side end portions of the first inclined plate 81, the second inclined plate 82, and the third inclined plate 83, and is formed so as to rise toward the hood front plate 10. The second rectifying plate 72a is formed so that the angle (second angle) formed by the second rectifying plate 72a and the face plates (hood right side plate 20, hood left side plate 30, hood bottom plate 50) having the ventilation holes 60 on the side of the outer wall 300 is larger than the first angle and smaller than 90 degrees, and is preferably 60 degrees.

[0056] The corner formed by the first inclined plate 81 and the second inclined plate 82 protrudes from the hood front plate 10 toward the outer wall 300.

[0057] The outdoor hood 100a has the above configuration.

[0058] (Features of Outdoor Hood 100a) Next, the features of the outdoor hood 100a will be described taking as an example a case where air transported from an indoor space is blown out from the outdoor hood 100a.

[0059] Air conveyed from an indoor space by a blower or the like (not shown) is sent to the outdoor hood 100a through a ventilation duct (not shown) and comes into contact with the wind direction adjustment plate 80. The air that comes into contact with the wind direction adjustment plate 80 becomes an air flow that is divided into three directions along the first inclined plate 81, the second inclined plate 82, and the third inclined plate 83, and moves to the ventilation hole 60. Therefore, compared to the case where the wind direction adjustment plate 80 is not provided, the amount of air that remains in the inner peripheral space formed between the outdoor hood 100a and the outer wall 300 can be reduced, and the pressure loss of the outdoor hood 100a is reduced. This makes it possible to obtain an outdoor hood 100a that suppresses the dirt on the outer wall 300 while suppressing the decrease in the ventilation amount due to pressure loss.

[0060] [Variations] The following describes a modified example of the second embodiment. In the drawings and description of the modified example, the same components and members as those in the embodiment are given the same reference numerals. Explanations that overlap with the embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from the embodiment.

[0061] In the second embodiment, the first current plate 71 may be provided with the upright portion 71c described in the modified example of the first embodiment of the present invention, and similar advantageous effects as described in the modified example of the first embodiment can be expected.

[0062] In the second embodiment, the hood front panel 10 has a rectangular shape, but the rectangular shape includes a square shape.

[0063] The outdoor hood 100a may include a third current plate between the first current plate 71 and the second current plate 72a, which controls the airflow of air passing through the ventilation holes 60. The third current plate is a flat plate that stands toward the outer wall 300 in an inner circumferential space formed by the outer wall 300 and the outdoor hood 100a. The third current plate has an angle (third angle) on the outer wall 300 side formed by the face plate (hood right face plate 20, hood left face plate 30, hood bottom face plate 50) having the ventilation holes 60 and the third current plate, which is the same as the second angle. The third current plate has the same effect as the second current plate 72a.

[0064] (Configuration of outdoor hood 100b according to embodiment 3) The configuration of an outdoor hood 100b according to a third embodiment of the present invention will be described with reference to Figures 7 to 10. In Figures 7 to 10, the same components as those in Figures 1 to 4 are designated by the same reference numerals, and detailed descriptions thereof will be omitted.

[0065] Fig. 7 is an exploded perspective view showing the configuration of the outdoor hood 100b. Fig. 8 is a first external perspective view showing the configuration of the base portion 200 of Fig. 7. Fig. 9 is an external perspective view showing the configuration of the base portion 200 of Fig. 7. Fig. 10 is an assembled side view in which a portion of the outdoor hood 100b is enlarged.

[0066] The outdoor hood 100b has a different configuration from the outdoor hood 100 in that it includes a base portion 200, but has the same configuration as the outdoor hood 100 in other respects.

[0067] The base portion 200 is a member provided between the outdoor hood 100b and the exterior wall 300. The base portion 200 is installed on the exterior wall 300 via screws or caulking material (adhesive). The base portion 200 and the outdoor hood 100b each have a fitting portion (not shown) for fitting with each other. The outdoor hood 100b is installed on the exterior wall 300 via the base portion 200 by fitting with the base portion 200. The base portion 200 has a base bottom plate 210, a base frame 220, a base duct 230, and a water drain plate 240.

[0068] The base bottom plate 210 is a square-shaped plate having an opening that communicates with the outdoor hood 100b.

[0069] The base frame 220 is a rectangular frame body standing in a substantially vertical direction with the base bottom plate 210 as a base end. The standing tip of the base frame 220 abuts against the outer wall 300. When the tip of the base frame 220 abuts against the outer wall 300, the base part 200 forms an inner peripheral space (not shown) with the base bottom plate 210, the base frame 220, and the outer wall 300. The base frame 220 is made up of a base upper side plate 221, a base lower side plate 222, a base right side plate 223, and a base left side plate 224.

[0070] The base upper side plate 221 is a flat plate member disposed above the base duct 230 .

[0071] The base lower side panel 222 is disposed below the base duct 230 and is a flat plate member having a drain opening 225 .

[0072] The drain opening 225 communicates the inner peripheral space formed by the base portion 200 and the outer wall 300 with the space outside thereof.

[0073] The base right side plate 223 is a flat plate member that stands up from one end side of the base upper side plate 221 to the base lower side plate 222.

[0074] The base left side plate 224 is a flat plate member that stands up from the other end side of the base upper side plate 221 to the base lower side plate 222.

[0075] The base duct 230 is a cylindrical body standing in a substantially vertical direction with the outer peripheral end of the opening of the base bottom plate 210 as its base end. The base duct 230 can be inserted into and removed from the ventilation opening 301. The base duct 230 communicates with a space connected to the other end of the duct by connecting its tip end to one end of a duct (not shown). The base duct 230 is disposed on the inner peripheral side of the base frame 220.

[0076] The water draining plate 240 is a plate material for separating and dropping water droplets running down the outer wall 300 or water droplets that have entered the inner peripheral space formed by the base frame 220 and the outer wall 300 from the outer wall 300. The water draining plate 240 is disposed on the upper side of the hood bottom plate 50 and on one end side and the other end side of the base lower side plate 222. In other words, the water draining plate 240 is not provided continuously from one end to the other end of the base lower side plate 222, but is disposed at two locations, one end side and the other end side of the base lower side plate 222. The water draining plate 240 is disposed on the outer peripheral side of the ventilation hole 60 in the direction connecting the hood right side plate 20 and the hood left side plate 30. The water draining plate 240 is formed of a first standing portion 241, a second standing portion 242, and a third standing portion 243.

[0077] The first upright portion 241 is a plate member that stands vertically downward relative to the upright surface of the base lower side plate 222. The upright tip of the first upright portion 241 is located above the hood bottom plate 50.

[0078] The second standing portion 242 is a plate member that stands obliquely downward toward the hood front panel 10, with the standing tip of the first standing portion 241 as a base end. The standing tip of the second standing portion 242 is located at the same position as the hood bottom plate 50, or above the hood bottom plate 50 when the base portion 200 is installed on the outer wall 300. In other words, "the drain plate 240 is provided above the hood bottom plate 50" means that the standing tip of the second standing portion 242 is located at the same position as the hood bottom plate 50, or above the hood bottom plate 50 when the base portion 200 is installed on the outer wall 300.

[0079] The third upright portion 243 is a plate member that stands in the upright direction of the second upright portion 242, with the ridgeline in the upright direction of the first upright portion 241 as its base end. The upright tip of the third upright portion 243 is located at the same position as the hood bottom plate 50 or above the hood bottom plate 50.

[0080] The outdoor hood 100b has the above configuration.

[0081] (Features of Outdoor Hood 100b) First, as a comparative example, a water drain plate 240 in a case where the outdoor hood 100b does not include the flow straightening portion 70 will be described.

[0082] In the case of the outdoor hood 100b without the straightening section 70, in a state where the base section 200 is installed on the outer wall 300, the water drain plate 240 must be disposed so that it protrudes downward from the hood bottom plate 50 and covers at least a part of the ventilation hole 60 when the ventilation hole 60 is viewed from below the hood bottom plate 50. This is because the water drain plate 240 is used not only for the purpose of separating water droplets from the outer wall 300 and dripping them, but also for the purpose of moving the airflow blowing out of the ventilation hole 60 away from the outer wall 300. Since the water drain plate 240 protrudes downward from the hood bottom plate 50, the visibility of the water drain plate 240 when looking up at the outdoor hood 100b from below is higher than when it does not protrude. Therefore, the design of the outdoor hood 100b may be impaired by the water drain plate 240.

[0083] In contrast, in the outdoor hood 100b of the present application, the airflow blown out from the ventilation holes 60 can be directed away from the outer wall 300 by the straightening section 70, so there is no need to actively use the water draining plate 240 for the purpose of directing the airflow blown out from the ventilation holes 60 away from the outer wall 300. Therefore, in a state in which the base section 200 is installed on the outer wall 300, the water draining plate 240 may be provided on the upper side with respect to the hood bottom plate 50. Therefore, the visibility of the water draining plate 240 when the outdoor hood 100b is viewed from below can be reduced compared to the outdoor hood 100b of the comparative example. Therefore, it is expected to have the effect of reducing the possibility that the design of the outdoor hood 100b will be impaired by the water draining plate 240.

[0084] Furthermore, water droplets that have entered the inner peripheral space formed by the base frame 220 and the outer wall 300 are discharged to the drainage plate 240 from the drainage openings 225 provided in the base lower side panel 222. Therefore, it is sufficient to dispose the drainage plate 240 in two places, one end side and the other end side of the base lower side panel 222. Therefore, while preventing the outer wall from becoming dirty, the size of the drainage plate 240 can be made smaller than that of the outdoor hood 100b of the comparative example, and cost rationalization can be expected by reducing the material cost of the drainage plate 240.

[0085] [Variations] Below, a modified example of the third embodiment will be described. In the drawings and description of the modified example, the same components and members as those in the embodiment will be given the same reference numerals. Explanations that overlap with the embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from the embodiment.

[0086] In the third embodiment, the base lower side plate 222 is a flat plate material, but is not limited thereto. For example, the base lower side plate 222 may be an L-shaped plate material bent toward the base duct 230 side, or may be a plate material curved toward the base duct 230 side. As a result, a slope descending toward the drain opening 225 is formed in the base lower side plate 222, so that it is expected to have an effect of actively draining water droplets that have entered the inner peripheral space formed by the base frame 220 and the outer wall 300.

[0087] The present invention has been described above based on the embodiment. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each processing process, and that such modifications are also within the scope of the present invention. In the above-mentioned embodiment, the contents for which such design changes are possible are described with the notation "in the embodiment" or "in the embodiment", but this does not mean that design changes are not permitted for contents without such notation. [Industrial Applicability]

[0088] The outdoor hood of the present invention makes it possible to suppress an increase in pressure loss, increase ventilation volume, while suppressing dirt on exterior walls, and is therefore useful as an exterior component to be connected to the end of a ventilation duct connecting the indoors and outdoors.
