[0029] (Embodiment)

[0030] (1. Overall Structure of the Air Guide)

[0031] Hereinafter, the air guide member 1 of the embodiment of the present invention will be described using Figure 1A 、 Figure 1B and Figure 2 as a reference.

[0032] Figure 1A FIG. Figure 1B is a perspective view showing the structure of the air guide member 1, Figure 2 FIG.

[0033] is an exploded perspective view of the components of the air guide member 1, Figure 1A and Figure 1B FIG. Figure 1A and Figure 1B are cross-sectional views in the short side direction of the air guide member 1.

[0034] Here, as shown in

[0035] and Figure 2 a rectangular coordinate system including the x-axis, y-axis, and z-axis is defined. The x-axis and y-axis are orthogonal to each other. The z-axis is perpendicular to the x-axis and y-axis and extends in the up and down direction of the air guide member 1. In addition, the positive directions of the x-axis, y-axis, and z-axis are defined as the directions of the arrows in

[0036] and Figure 1A and Figure 1BAs shown, the air guide member 1 is configured to include a first outer air guide member 10, a second outer air guide member 20, a first inner air guide member 30, a second inner air guide member 40, a plurality of fins 50, and a top plate 60. The first outer air guide member 10 and the second outer air guide member 20 can be combined in the left-right direction, and details will be described later.

[0037] (1.1 Structure of the outer air guide member component)

[0038] The outer air guide member component combined with the first outer air guide member 10 and the second outer air guide member 20 has a quadrangular prism shape extending in the front-rear direction and has a hollow space 2 inside (refer to Figure 2 ). In the hollow space 2, as the inner air guide member component, the first inner air guide member 30 and the second inner air guide member 40 are symmetrically arranged when observed in the front-rear direction. Through the plurality of fins 50 installed on the inner air guide member component, the air flowing in the hollow space 2 is guided to the blowing opening 3.

[0039] The first outer air guide member 10 is one of the components constituting the outer frame of the air guide member 1. As shown in Figure 1B and Figure 2 , the first outer air guide member 10 includes: an upper surface 11 having a plate shape extending in the front-rear direction and the left-right direction (formed on a plane parallel to the x-y plane); an outer side surface 12 (the first outer side surface) having a plate shape extending in the front-rear direction and the up-down direction from the lower side of the left end of the upper surface 11 (formed on a plane parallel to the x-z plane); and a lower surface 13 extending in the front-rear direction and the left-right direction from the right side of the lowermost part of the outer side surface 12 (formed on a plane parallel to the x-y plane).

[0040] In addition, a lower end portion 14 (the first lower end portion) having a plate shape extending in the front-rear direction and the up-down direction from the upper side of the right end of the lower surface 13 (formed on a plane parallel to the x-z plane) is also included in the first outer air guide member 10. That is, it is configured such that the upper surface 11 of the first outer air guide member 10 faces the lower surface 13. In addition, it is configured such that the outer side surface 12 of the first outer air guide member 10 faces the lower end portion 14.

[0041] Therefore, when viewed in the cross-section of the first outer air guide member 10 in the y-z plane, it has a substantially C-shaped (essentially C-shaped) configuration, and is configured such that an opening 17 (the first opening) in a substantially C-shape extends in the front-rear direction (long side direction). The opening 17 is formed between the upper end portion 16 on the right side of the upper surface 11, i.e., the upper end portion of the upper side end and the upper end portion of the lower side end 14. In other words, the first outer air guide member 10 has a substantially C-shaped configuration in the cross-section in the short side direction, and can be said to be a shape in which the opening 17 in a substantially C-shape extends in the long side direction. In this way, the first outer air guide member 10 has a simple configuration of a plate shape (formed of a plate-shaped member), and thus can be easily manufactured by processing a sheet metal part.

[0042] The second outer air guide member 20 is one of the members constituting the outer frame of the air guide member 1. As Figure 1B and Figure 2 shown, the second outer air guide member 20 includes: an upper surface 21 in a plate shape that extends in the front-rear direction and the left-right direction (formed on a plane parallel to the x-y plane); a plate-shaped outer side surface 22 (the second outer side surface) that extends from the lower side of the right end portion of the upper surface 21 in the front-rear direction and the up-down direction (formed on a plane parallel to the x-z plane); and a lower surface 23 that extends from the left side of the lowermost portion of the outer side surface 22 in the front-rear direction and the left-right direction (formed on a plane parallel to the x-y plane).

[0043] In addition, a plate-shaped lower end portion 24 (the second lower end portion) that extends from the upper side of the left end portion of the lower surface 23 in the front-rear direction and the up-down direction (formed on a plane parallel to the x-z plane) is also included in the second outer air guide member 20. That is, it is configured such that the upper surface 21 of the second outer air guide member 20 faces the lower surface 23. In addition, it is configured such that the outer side surface 22 of the second outer air guide member 20 faces the lower end portion 24.

[0044] Therefore, when viewed in the cross-section of the second outer air guide member 20 in the y-z plane, it has a substantially reverse C-shaped (essentially reverse C-shaped) configuration, and is configured such that an opening 27 (the second opening) in a substantially reverse C-shape extends in the front-rear direction (long side direction). The opening 27 is formed between the upper end portion 26 on the left side of the upper surface 21, i.e., the upper end portion of the upper side end and the upper end portion of the lower end portion 24. In other words, it can be said that the second outer air guide member 20 has a substantially reverse C-shaped configuration in the cross-section in the short side direction, and is a shape in which the opening 27 in a substantially reverse C-shape extends in the long side direction. In this way, the second outer air guide member 20 has a simple configuration of a plate shape (formed of a plate-shaped member), and thus can be easily manufactured by processing a sheet metal part.

[0045] In addition, when observed in the cross-section in the short side direction, the first outer air guide member 10 and the second outer air guide member 20 have a shape that is substantially line-symmetric with respect to the z-axis.

[0046] As Figure 2 shown, in the air guide member 1, the upper surface 21 of the second outer air guide member 20 is overlapped on and in contact with the upper surface 11 of the first outer air guide member 10, and the lower end portion 14 of the first outer air guide member 10 is brought close to and opposed to the lower end portion 24 of the second outer air guide member 20. Thus, the first outer air guide member 10 and the second outer air guide member 20 are combined. In addition, both the upper surface 11 of the first outer air guide member 10 and the upper surface 21 of the second outer air guide member 20 can face upward.

[0047] In other words, the upper surface 11 of the first outer air guide member 10 and the upper surface 21 of the second outer air guide member 20 are arranged in parallel with each other and are configured to be in surface contact in the vertical direction. Here, surface contact means that when observed from the vertical direction (z-axis direction or -z-axis direction) of the contact surface, the two members overlap in the short side direction (y-axis direction) by 10 mm or more and similarly (substantially over the entire area) in the long side direction (x-axis direction).

[0048] On the other hand, in the air guide member 1, when observed in the cross-section in the short side direction, the lower end portion 14 of the first outer air guide member 10 and the lower end portion 24 of the second outer air guide member 20 are arranged at a predetermined interval and in parallel with each other (refer to Figure 2 ). As a result, by combining the first outer air guide member 10 and the second outer air guide member 20, the air guide member 1 having a substantially quadrangular prism shape (including the quadrangular prism shape) extending in the front-rear direction can be formed. And a hollow space 2 is formed inside the air guide member 1 constituted by this combination. In other words, the hollow space 2 is formed by combining the opening 17 of the first outer air guide member 10 and the opening 27 of the second outer air guide member 20 so as to face each other.

[0049] In the air guide member 1, in a state where the first outer air guide member 10 and the second outer air guide member 20 are combined, the first outer air guide member 10 and the second outer air guide member 20 are fixed by fastening using screws in the threaded portion 18 provided on the upper surface 11 and the threaded portion 28 provided on the upper surface 21 (refer to Figure 1A and Figure 1B ).

[0050] In addition, in the air guide member 1, in a state where the first outer air guide member 10 and the second outer air guide member 20 are combined, the lower end portion 14 of the first outer air guide member 10 and the lower end portion 24 of the second outer air guide member 20 are arranged at a predetermined interval and in parallel with each other (refer to Figure 2) Thus, the opening lower end portion 15, which is the lower end portion of the lower end portion 14 of the first outer air guide member 10, and the opening lower end portion 25, which is the lower end portion of the lower end portion 24 of the second outer air guide member 20, are arranged so as to be separated from each other, and a blowing opening 3 is formed in the separated portion.

[0051] In other words, the blowing opening 3 is formed by opposing the lower end portion 14 of the first outer air guide member 10 and the lower end portion 24 of the second outer air guide member 20. That is, the lower end portion 14 of the first outer air guide member 10 and the lower end portion 24 of the second outer air guide member 20 respectively form end faces in a state of standing upright upward in the vertical direction from the lower surfaces 13 and 23, and constitute the blowing opening 3.

[0052] Details of the blowing opening 3 will be described later. It is a slit-shaped opening that blows out the air flowing in the air passage 4 inside the hollow space 2 to the outside, and extends in the x-axis direction when the outer air guide member is viewed in the z-axis direction from below, and is also referred to as a "blowout port". The blowing opening 3 has a shape extending along the long side direction (x-axis direction).

[0053] In addition, as Figure 1A and Figure 1B shown, in the combination of the first outer air guide member 10 and the second outer air guide member 20, the end portion of the front y-z plane is open, and the end portion of the rear y-z plane is closed by the plate-shaped top plate 60.

[0054] In the combination of the first outer air guide member 10 and the second outer air guide member 20, the front opening is connected to a fan (not shown), and the air flow from the fan enters the hollow space 2 from the front opening. Therefore, an air passage 4 connected to the blowing opening 3 is arranged in the hollow space 2.

[0055] The top plate 60 is a member that closes one of the openings at both ends in the long side direction of the air guide member 1 (for example, the rear opening). The top plate 60 is fixed to the first outer air guide member 10 and the second outer air guide member 20 by screw fastening or the like.

[0056] (1.2 Structure of the inner air guide member)

[0057] Next, the inner air guide members (the first inner air guide member 30 and the second inner air guide member 40) that guide the air flowing inside the air guide member 1 to the blowing opening 3 will be described using Figure 2 and Figures 3A to 3C .

[0058] Figure 3A is a perspective view of the first inner air guide member 30, Figure 3B is a perspective view of the second inner air guide member 40, Figure 3C is a cross-sectional view of the inner air guide member in the short side direction.

[0059] On the air guide member 1, as an inner air guide member part that guides the air flowing inside toward the blowout opening 3, a first inner air guide member 30 and a second inner air guide member 40 are respectively provided on the first outer air guide member 10 and the second outer air guide member 20.

[0060] The first inner air guide member 30 is a member mounted on the first outer air guide member 10. As Figure 2 , Figure 3A and Figure 3C shown, when observed in the cross-section of the y-z plane, the first inner air guide member 30 has three straight portions and is formed to extend in the front-rear direction. Specifically, the first inner air guide member 30 is configured to have a first lower end portion 31, a first upper end portion 32, and a first rectifying portion 33.

[0061] The first lower end portion 31 has a plate-like shape parallel to the x-z plane that extends in the front-rear direction and the up-down direction. As Figure 2 shown, the first lower end portion 31 is a portion of the first inner air guide member 30 that is in surface contact with the lower side end portion 14 of the first outer air guide member 10.

[0062] The first upper end portion 32 has a plate-like shape parallel to the x-z plane that extends in the front-rear direction and the up-down direction. As Figure 2 shown, the first upper end portion 32 is a portion of the first inner air guide member 30 that is in surface contact with the outer side surface 12 of the first outer air guide member 10 opposite to the lower side end portion 14.

[0063] The first rectifying portion 33 has a plate-like shape that connects the uppermost portion of the first lower end portion 31 and the lowermost portion of the first upper end portion 32 and extends in the front-rear direction in the cross-section of the y-z plane. The first rectifying portion 33 is a portion that guides the air flowing inside the air guide member 1 toward the blowout opening 3 on the side of the first inner air guide member 30 of the inner air guide member part. A plurality of first slits 34 for inserting fins 50 (described later) in the -z axis direction (downward direction) are provided at a prescribed interval in the front-rear direction in the first rectifying portion 33 (refer to Figure 3A ).

[0064] The first slit 34 is provided in the first rectifying portion 33 and is provided up to the first lower end portion 31 side of the first rectifying portion 33, that is, the uppermost portion of the first lower end portion 31. The fins 50 are inserted through the first slit 34 (refer to Figure 1B and Figure 2 ).

[0065] As described above, the first inner air guide member 30 is configured to have a first lower end portion 31 that is in surface contact with the lower side end portion 14 of the first outer air guide member 10, a first upper end portion 32 that is in surface contact with the outer side surface 12 of the first outer air guide member 10 opposite to the lower side end portion 14, and a first rectifying portion 33 that connects the first lower end portion 31 and the first upper end portion 32.

[0066] Thus, the first inner air guide member 30 has a simple structure formed of a plate shape, and thus can be easily manufactured by processing a sheet metal component. The first inner air guide member 30 is provided in the first outer air guide member 10 and has a function of guiding the air flowing in the hollow space 2 toward the blowing opening 3 when observed in a cross section in the short side direction.

[0067] The second inner air guide member 40 has a structure (mirror image body) that is substantially symmetric with respect to the z-axis in the cross section in the short side direction with respect to the first inner air guide member 30.

[0068] The second inner air guide member 40 is a component mounted on the second outer air guide member 20. As Figure 2 、 Figure 3B and Figure 3C shown, the second inner air guide member 40 has three straight portions when observed in a cross section in the y-z plane (viewed from the cross section in the short side direction) and is formed to extend in the front-rear direction. Specifically, the second inner air guide member 40 is configured to have a second lower end portion 41, a second upper end portion 42, and a second rectifying portion 43.

[0069] The second lower end portion 41 has a plate shape parallel to the x-z plane that expands in the front-rear direction and the up-down direction. As Figure 2 shown, the second lower end portion 41 is a portion that is in surface contact with the lower side end portion 24 of the second outer air guide member 20 in the second inner air guide member 40.

[0070] The second upper end portion 42 has a plate shape parallel to the x-z plane that expands in the front-rear direction and the up-down direction. As Figure 2 shown, the second upper end portion 42 is a portion that is in surface contact with the outer side surface 22 of the second outer air guide member 20 in the second inner air guide member 40.

[0071] The second rectifying portion 43 has a plate shape that connects the uppermost portion of the second lower end portion 41 and the lowermost portion of the second upper end portion 42 and expands in the front-rear direction when observed in a cross section in the y-z plane. The second rectifying portion 43 is a portion that guides the air flowing inside the air guide member 1 toward the blowing opening 3 on the second inner air guide member 40 side of the inner air guide member component. A plurality of second slits 44 for inserting fins 50 (described later) in the -z axis direction (downward direction) are provided at a predetermined interval in the front-rear direction in the second rectifying portion 43 (refer to Figure 3B ).

[0072] The second slit 44 is provided in the second rectifying portion 43 and is provided up to the second lower end portion 41 side of the second rectifying portion 43, that is, the uppermost portion of the second lower end portion 41. The fins 50 are inserted through the second slit 44 (refer to Figure 1B and Figure 2 ).

[0073] Here, when observed in the long side direction, the first slit 34 and the second slit 44 are provided at positions that are line-symmetric with each other across the blowing opening 3, and are configured so that one (common) fin 50 can be inserted therethrough.

[0074] As described above, the second inner air guide member 40 is configured to have a second lower end portion 41 that is in surface contact with the lower end portion 24 of the second outer air guide member 20, a second upper end portion 42 that is in surface contact with the outer side surface 22 of the second outer air guide member 20 that faces the lower end portion 24, and a second rectifying portion 43 that connects the second lower end portion 41 and the second upper end portion 42.

[0075] In this way, since the second inner air guide member 40 has a simple structure formed of a plate shape, it can be easily manufactured by processing a sheet metal part. The second inner air guide member 40 is provided on the second outer air guide member 20 and has a function of guiding the air flowing in the hollow space 2 toward the blowing opening 3 when observed in a cross section in the short side direction.

[0076] When the first outer air guide member 10 and the second outer air guide member 20 are combined, as Figure 3C shown, the blowing opening 3 is disposed below the inner air guide member part. When observed in a cross section in the short side direction, the first inner air guide member 30 and the second inner air guide member 40 are symmetrically disposed with each other across the blowing opening 3. That is, when observed in a cross section in the short side direction, the first lower end portion 31 and the second lower end portion 41, the first upper end portion 32 and the second upper end portion 42, and the first rectifying portion 33 and the second rectifying portion 43 are respectively disposed symmetrically left and right with each other across the blowing opening 3.

[0077] In addition, in the air guide member 1, as Figure 2 and Figure 3C shown, when observed in a cross section in the y-z plane, the hollow space 2 is configured to gradually narrow toward the blowing opening 3 through the first rectifying portion 33 and the second rectifying portion 43 of the inner air guide member part. That is, the distance between the uppermost part of the first lower end portion 31 and the uppermost part of the second lower end portion 41 is narrower than the distance between the lowermost part of the first upper end portion 32 and the lowermost part of the second upper end portion 42. In other words, the separation distance between the first lower end portion 31 and the second lower end portion 41 is configured to be smaller than the separation distance between the first upper end portion 32 and the second upper end portion 42.

[0078] (1.3 Structure of the fin)

[0079] Next, the fin 50 attached to the inner air guide member part (the first inner air guide member 30 and the second inner air guide member 40) will be described using Figure 2 , Figure 4A and Figure 4B .

[0080] Figure 4A is a schematic diagram of the fin 50, Figure 4BIt is an enlarged perspective view of the insertion part into which the inward air guiding member part of the fin 50 is inserted.

[0081] The fins 50 are provided at multiple positions in the long side direction of the inner air guiding member part, and are used to divide a part of the hollow space 2 (the space part where the first inner air guiding member 30 and the second inner air guiding member 40 are arranged opposite to each other) into multiple parts in the long side direction, and are also used to keep the opening width of the blowing opening 3 constant.

[0082] Specifically, as Figure 4A shown, the fin 50 has a plate shape that extends in the vertical and horizontal directions (parallel to the y-z plane). In addition, the length of the fin 50 in the vertical direction is slightly shorter than the sum of the lengths of the first lower end part 31 and the first rectifying part 33 of the first inner air guiding member 30 in the vertical direction (refer to Figure 2 ).

[0083] As Figure 4A shown, the fin 50 has a first inner contact part 51, a second inner contact part 52, a first protruding part 53, a second protruding part 54, a first notch part 55, and a second notch part 56.

[0084] In the front view, the first inner contact part 51 is a part of the upper end edge on the side of the first inner air guiding member 30 (left side) of the fin 50. As Figure 2 shown, the first inner contact part 51 is processed into an angle parallel to the plane of the first rectifying part 33 of the first inner air guiding member 30. In the state where the fin 50 is installed on the inner air guiding member part, the entire first inner contact part 51 is in close contact with and fixed to the first rectifying part 33.

[0085] In the front view, the second inner contact part 52 is a part of the upper end edge on the side of the second inner air guiding member 40 (right side) of the fin 50. As Figure 2 shown, the second inner contact part 52 is processed into an angle parallel to the plane of the second rectifying part 43 of the second inner air guiding member 40. In the state where the fin 50 is installed on the inner air guiding member part, the entire second inner contact part 52 is in close contact with and fixed to the second rectifying part 43.

[0086] As Figure 4A shown, the first protruding part 53 protrudes in a triangular shape in a direction extending more to the left than the extension line of the first inner contact part 51. Thus, when the fin 50 is inserted through the first slit 34 of the first inner air guiding member 30 from above, as Figure 2 shown, it becomes a state of protruding to the back side of the first rectifying part 33 (the side not facing the hollow space 2).

[0087] That is, the first protruding portion 53 functions as a detachment prevention mechanism that prevents the fin 50 from detaching upward from the first gap 34 when the fin 50 is inserted through the first gap 34 of the first inner air guide member 30 from above.

[0088] As Figure 4A shown, the second protruding portion 54 protrudes in a triangular shape in a direction extending more to the right than the extension line of the second inner contact portion 52. Thus, when the fin 50 is inserted through the second gap 44 of the second inner air guide member 40 from above, as Figure 2 and Figure 4B shown, it becomes a state of protruding toward the back side of the second rectifying portion 43 (the side not facing the hollow space 2).

[0089] That is, the second protruding portion 54 functions as a detachment prevention mechanism that prevents the fin 50 from detaching upward from the second gap 44 when the fin 50 is inserted through the second gap 44 of the second inner air guide member 40 from above.

[0090] In addition, the shapes of the first protruding portion 53 and the second protruding portion 54 are not limited to the above-described triangular shape, and may be other shapes. Further, as the detachment prevention mechanism, various detachment prevention mechanisms can be used in addition to the method of forming the first protruding portion 53 and the second protruding portion 54.

[0091] As Figure 4A shown, the first notch portion 55 is provided on the left side of the lower end portion of the fin 50. As Figure 2 shown, the first notch portion 55 is provided in such a manner that when the fin 50 is inserted through the first gap 34 of the first inner air guide member 30 from above, the lower end portion 14 of the first outer air guide member 10 and the first lower end portion 31 of the first inner air guide member 30 are clamped.

[0092] That is, the first notch portion 55 is processed to have a width that adds together the plate thickness of the lower end portion 14 of the first outer air guide member 10 and the plate thickness of the first lower end portion 31 of the first inner air guide member 30. In addition, the depth (length) of the first notch portion 55 in the vertical direction is slightly shorter than the length of the first lower end portion 31 of the first inner air guide member 30. That is, it becomes a length such that the lower end of the fin 50 does not contact the lower surface 13 of the first outer air guide member 10. Thereby, the cleanability of the blowing opening 3 can be improved, and since the fin 50 does not protrude to the outside of the device, safety can be improved.

[0093] As Figure 4A shown, the second notch portion 56 is provided on the right side of the lower end portion of the fin 50. As Figure 2As shown, the second notch portion 56 is provided in such a manner that when the fin 50 is inserted through the second slit 44 of the second inner air guiding member 40 from above, the lower end portion 24 of the second outer air guiding member 20 and the second lower end portion 41 of the second inner air guiding member 40 are clamped therebetween.

[0094] That is, the second notch portion 56 is processed to have a width that adds together the plate thickness of the lower end portion 24 of the second outer air guiding member 20 and the plate thickness of the second lower end portion 41 of the second inner air guiding member 40. In addition, the depth (length) of the second notch portion 56 in the vertical direction is slightly shorter than the length of the second lower end portion 41 of the second inner air guiding member 40. That is, it becomes a length such that the lower end of the fin 50 does not contact the lower surface 23 of the second outer air guiding member 20. Thereby, the cleanability of the blowing opening 3 can be improved, and the fin 50 does not protrude to the outside of the device, so the safety can be improved.

[0095] In other words, in the air guiding member 1, as Figure 2 and Figure 4B shown, the fin 50 penetrates the first slit 34 and the second slit 44 from above the first inner air guiding member 30 and the second inner air guiding member 40, and the first protruding portion 53 and the second protruding portion 54 are respectively inserted and protrude from the first slit 34 and the second slit 44. And, the first rectifying portion 33 of the first inner air guiding member 30 contacts the first inner contact portion 51 of the fin 50, and the second rectifying portion 43 of the second inner air guiding member 40 contacts the second inner contact portion 52 of the fin 50.

[0096] In addition, the lower end portion 14 of the first outer air guiding member 10 and the first lower end portion 31 of the first inner air guiding member 30 are inserted into the first notch portion 55. The lower end portion 24 of the second outer air guiding member 20 and the second lower end portion 41 of the second inner air guiding member 40 are inserted into the second notch portion 56.

[0097] The distance between the uppermost part of the first slit 34 and the uppermost part of the second slit 44 is formed to be several millimeters smaller than the distance between the first protruding portion 53 and the second protruding portion 54 of the fin 50. Therefore, only by inserting the fin, the first protruding portion 53 and the second protruding portion 54 exhibit an anti-disengagement function, and the fin 50 can be prevented from disengaging from the first inner air guiding member 30 and the second inner air guiding member 40.

[0098] In addition, the lower end portion 14 of the first outer air guiding member 10 and the first lower end portion 31 of the first inner air guiding member 30 are clamped by the first notch portion 55, and the lower end portion 24 of the second outer air guiding member 20 and the second lower end portion 41 of the second inner air guiding member 40 are clamped by the second notch portion 56. Thereby, the positional deviation of each component in the left-right direction is restricted, and the width of the blowing opening 3 can be maintained constant. In other words, the distance between the lower end portion 15 of the opening of the first outer air guiding member 10 and the lower end portion 25 of the opening of the second outer air guiding member 20 can be maintained constant.

[0099] Moreover, the above-mentioned fins 50 are installed at a plurality of positions at a prescribed interval in the longitudinal direction of the air guide member 1. Thus, the first outer air guide member 10, the second outer air guide member 20, the first inner air guide member 30, and the second inner air guide member 40 that constitute the air guide member 1 interact with each other and are reliably fixed over the entire region in the longitudinal direction. In addition, the distance between the lower end portion 15 of the opening of the first outer air guide member 10 and the lower end portion 25 of the opening of the second outer air guide member 20 can be maintained constant over the entire region in the longitudinal direction.

[0100] As described above, the fins 50 divide a part of the hollow space 2 (the space portion where the first inner air guide member 30 and the second inner air guide member 40 are disposed opposite to each other) into a plurality of parts in the longitudinal direction, and maintain the opening width of the blowing opening 3 constant.

[0101] (2. Air flow inside the air guide member)

[0102] Next, Figure 5 Regarding the case where the air guide member 1 is provided in such a manner that the air from a fan (not shown) is introduced into the air guide member 1, the flow of the air flowing inside the air guide member 1 will be described.

[0103] Figure 5 is a schematic diagram showing the path of the air flow inside the air guide member 1. In Figure 5 , the state where the air introduced into the inside of the air guide member 1 flows from the front side to the rear side (-x-axis direction) is shown.

[0104] The air guide member 1 has a hollow space 2 inside. When the air from the fan is introduced into the air guide member 1, the air from the fan (air flow AF0) flows through the hollow space 2 from the front side to the rear side. That is, the hollow space 2 functions as the air passage 4 for the air flow AF0.

[0105] Since the air flow AF0 is the air (high-pressure air) boosted (compressed) by the fan, the air flow AF0 flowing in the air passage 4 flows toward the atmospheric space side with a lower pressure. That is, the air flow AF0 flowing in the air passage 4 is blown out into the atmospheric space through the blowing opening 3.

[0106] More specifically, as Figure 5 shows, when air (air flow AF0) is supplied to the inside of the air passage 4 from the front side to the rear side by a fan (not shown), the air flow AF0 is blown downward as the blowing air flow AF1 through the blowing opening 3. At this time, by having a plurality of fins 50, each fin 50 functions as a flow rectifying member, and compared with the case where there are no fins 50, the air blown out from the blowing opening 3 can be uniformly blown along the longitudinal direction.

[0107] In addition, when the air flow AF0 goes from the upper side to the lower side, through the first flow rectifying portion 33 and the second flow rectifying portion 34 (in Figure 5(not shown in the figure), the width of the air passage (the width of the hollow space 2) gradually narrows as it approaches the blowing opening 3, so that disturbances in the flow are suppressed and air can be blown efficiently.

[0108] (3. Effects, etc.)

[0109] As described above, the air guide member 1 according to the present embodiment can achieve the following effects.

[0110] (1) The air guide member 1 includes: a first outer air guide member 10 having a substantially C-shaped cross-section (substantially C-shaped) when viewed in the short-side direction, and the opening (17) of the substantially C-shaped cross-section (the first opening) extends along the long-side direction; a second outer air guide member 20 having a substantially reverse C-shaped cross-section (substantially reverse C-shaped) when viewed in the short-side direction, and the opening 27 of the substantially reverse C-shaped cross-section (the second opening) extends along the long-side direction; a hollow space 2 formed by combining the opening 17 of the first outer air guide member 10 and the opening 27 of the second outer air guide member 20 in a facing manner; a blowing opening 3 formed by opposing the lower end portion 14 (the first lower end portion) of the opening 17 of the first outer air guide member 10 and the lower end portion 24 (the second lower end portion) of the opening 27 of the second outer air guide member 20; a first inner air guide member 30 provided on the first outer air guide member 10, which guides the air flowing in the hollow space 2 to the blowing opening 3 when viewed in the short-side direction; a second inner air guide member 40 provided on the second outer air guide member 20, which guides the air flowing in the hollow space 2 to the blowing opening 3 when viewed in the short-side direction; and a plurality of fins 50 that divide a part of the hollow space 2 in the long-side direction into a plurality of spaces and keep the opening width of the blowing opening 3 constant. The lower end portion 14 of the first outer air guide member 10 and the lower end portion 24 of the second outer air guide member 20 respectively constitute the blowing opening 3 in a state of being erected upward in the vertical direction. The first inner air guide member 30 has a first lower end portion 31 that is in surface contact with the lower end portion 14 of the first outer air guide member 10, a first upper end portion 32 that is in surface contact with the outer side surface 12 of the first outer air guide member 10 opposite to the lower end portion 14, and a first rectifying portion 33 that connects the first lower end portion 31 and the first upper end portion 32. The second inner air guide member 40 has a second lower end portion 41 that is in surface contact with the lower end portion 24 of the second outer air guide member 20, a second upper end portion 42 that is in surface contact with the outer side surface 22 of the second outer air guide member 20 opposite to the lower end portion 24, and a second rectifying portion 43 that connects the second lower end portion 41 and the second upper end portion 42.

[0111] By being configured in such a structure, through a simple combination structure of each component, the first outer air guide member 10 and the first inner air guide member 30 are fixed in a surface-contact manner, and the second outer air guide member 20 and the second inner air guide member 40 are fixed in a surface-contact manner. Therefore, when air is made to flow to the air guide member 1, air leakage from the internal hollow space 2 can be suppressed, and an increase in noise caused by air leakage can be suppressed. That is, in the air guide member 1, the complexity of the shape of the air guide member 1 can be alleviated, and the risk of noise increase can be reduced.

[0112] In addition, each component (the first outer air guide member 10, the second outer air guide member 20, the first inner air guide member 30, and the second inner air guide member 40) can be manufactured from a sheet metal part that has no curved portion when viewed in the cross-section in the short-side direction. Therefore, compared with the existing air supply cylinder (air guide member), the manufacturing process can be simplified, and the manufacturing cost can be reduced without the need for a mold or the like.

[0113] (2) It can also be configured such that a plurality of fins 50 are arranged in a manner that divides the space portion in the hollow space 2 where the first inner air guide member 30 and the second inner air guide member 40 are oppositely arranged in the longitudinal direction into a plurality of spaces.

[0114] According to such a structure, further utilizing the flow rectifying function of the fins 50, compared with the case where there are no fins 50, the air blown from the blowing opening 3 can be evenly blown in the longitudinal direction.

[0115] (3) It can also be configured such that in the air guide member 1, the first flow rectifying portion 33 and the second flow rectifying portion 43 are symmetrically arranged with respect to each other across the blowing opening 3 when viewed in the cross-section in the short-side direction, and when viewed in the cross-section in the short-side direction of the hollow space 2, the width of the hollow space 2 gradually becomes narrower toward the blowing opening 3 due to the first flow rectifying portion 33 and the second flow rectifying portion 43.

[0116] Thereby, when the air flow AF0 is from the upper side to the lower side, further suppression of flow disorder and the like can be achieved, and a stable blowing air flow AF1 can be blown out from the blowing opening 3. That is, as the air guide member 1, the blowing air flow AF1 can be efficiently blown out from the blowing opening 3.

[0117] (4) The vertical length of each of the plurality of fins 50 can also be shorter than the sum of the vertical lengths of the first lower end portion 31 of the first inner air guide member 30 and the first flow rectifying portion 33, and the sum of the vertical lengths of the second lower end portion 41 of the second inner air guide member 40 and the second flow rectifying portion 43, and the lower ends of the plurality of fins 50 do not contact the lower surfaces 13 of the first outer air guide member 10 and 23 of the second outer air guide member 20.

[0118] According to such a structure, the cleanability of the blowing opening 3 can be further improved, and the fins 50 do not protrude outside the device, so the safety can be improved.

[0119] (5) In the air guiding member 1, the first inner air guiding member 30 and the second inner air guiding member 40 each have a plurality of first gaps 34 and second gaps 44 for inserting a plurality of fins 50, and a detachment prevention mechanism for preventing detachment from the plurality of first gaps 34 and second gaps 44 of the first inner air guiding member 30 and the second inner air guiding member 40 is provided on each of the plurality of fins 50.

[0120] Thus, the fins 50 do not detach from the first gap 34 and the second gap 44, so that the first outer air guiding member 10, the second outer air guiding member 20, the first inner air guiding member 30, and the second inner air guiding member 40 constituting the air guiding member 1 can interact and be reliably fixed, and the opening width of the blowing opening 3 can be maintained constant.

[0121] (6) Each of the plurality of fins 50 may also have: a first inner contact portion 51 formed in parallel with the plane of the first rectifying portion 33 of the first inner air guiding member 30; a second inner contact portion 52 formed in parallel with the plane of the second rectifying portion 43 of the second inner air guiding member 40; a first protruding portion 53 protruding outward beyond the extension line of the first inner contact portion 51; and a second protruding portion 54 protruding outward beyond the extension line of the second inner contact portion 52, and the detachment prevention mechanism is constituted by the first protruding portion 53 and the second protruding portion 54.

[0122] According to such a structure, the detachment prevention mechanism can be realized with a simple structure.

[0123] (7) Each of the plurality of fins 50 may also have: a first notch portion 55 provided at the lower end of each of the plurality of fins 50 and configured to sandwich the first lower end portion 14 of the first outer air guiding member 10 and the first lower end portion 31 of the first inner air guiding member 30; and a second notch portion 56 provided at the lower end of each of the plurality of fins 50 and configured to sandwich the second lower end portion 24 of the second outer air guiding member 20 and the second lower end portion 41 of the second inner air guiding member 40.

[0124] According to such a structure, the positional deviation of each component in the left - right direction is further restricted, and the width of the blowing opening 3 can be maintained constant.

[0125] (4. Application example of the air supply device)

[0126] Next, use Figure 6 , and an air supply device 100 as an application example of the air guiding member 1 is illustrated.

[0127] Figure 6It is a schematic perspective view of the air supply device 100 using multiple air guide members 1 of the application example.

[0128] The air supply device 100 is arranged in an indoor space such as an office, and is a device that generates an air flow blown from one side to the opposite side within the space. The air supply device 100 of the application example generates an air flow blown from the top surface side to the ground side.

[0129] Specifically, as Figure 6 shown, the air supply device 100 includes multiple air guide members 1, a suction port 102, a blower 103, and an air supply path (not shown). In addition, in the application example, 8 air guide members 1 of the embodiment are used as the multiple air guide members 1, but the number of the air guide members 1 of the present invention is not limited to this number.

[0130] The multiple air guide members 1 are respectively arranged in a manner of standing upright in the horizontal direction (x direction) from the wall surface 101. The multiple air guide members 1 are respectively connected to the wall surface 101 in such a way that air from the blower 103 is introduced through the air supply path at the end on the wall surface 101 side. In addition, the end of each air guide member 1 on the side opposite to the wall surface 101 is closed by a top plate 60.

[0131] When the multiple air guide members 1 are viewed in the cross-section in the short side direction of each air guide member 1 (viewed in the cross-section of the y-z plane), they are arranged in such a way that the lower surface of the blowing opening 3 of each air guide member 1 (a surface that is linear in the long side direction with a specified width) is arranged in the same plane (in this example, in a plane parallel to the x-y plane) (refer to Figure 7 ). In addition, the multiple air guide members 1 are arranged parallel to each other in the x-axis direction with a specified interval provided in the y-axis direction. In other words, the multiple air guide members 1 are arranged side by side with gaps in such a way that the lower surfaces of their respective blowing openings 3 are located in the same plane.

[0132] The suction port 102 is an opening for taking air into the interior of the wall surface 101. The suction port 102 is arranged below the wall surface 101 and sucks the air in the front space of the suction port 102. Here, the position where the suction port 102 is provided on the wall surface 101, that is, "below", means a region on the wall surface 101 at a height below the head of a person sitting in the indoor space, specifically, at a position 130 cm or less from the ground. The suction port 102 is, for example, Figure 7 shown as rectangular.

[0133] The blower 103 uses a well-known turbomachine such as a centrifugal blower. The blower 103 is disposed inside the wall surface 101, and supplies the air sucked from the suction port 102 to the plurality of air guiding members 1 through the air supply path inside the wall surface 101. In this application example, four blowers 103 are arranged, and the air flow generated by one blower 103 is transported to two air guiding members 1. In addition, the blower 103 may also be disposed outside the wall surface 101 (for example, in the space on the side opposite to the side where the air guiding members 1 are provided across the wall surface 101).

[0134] Next, use Figure 7 to describe the flow of the air flow in the air supply device 100 using the plurality of air guiding members 1 of the application example.

[0135] Figure 7 is a front view showing the flow of the air flow in the air supply device 100.

[0136] In the air supply device 100, when the blower 103 starts the air supply operation, air is sucked from the suction port 102, and the sucked air is supplied to the plurality of air guiding members 1 respectively.

[0137] The air supplied to the air guiding member 1 (the above-mentioned air flow AF0) flows inside the air guiding member 1 (hollow space 2) and is blown out as a blown air flow AF1 from the blowout opening 3. When the blown air flow AF1 is blown out from the blowout opening 3, a guiding air flow AF2 is generated in the gap between the air guiding members 1 by being pulled by the blown air flow AF1. And, the blown air flow AF1 and the guiding air flow AF2 are combined to generate a linear air flow AF3 as a whole. That is, the air supply device 100 can blow out the air flow AF3 that becomes a downward flow as a surface air flow having a uniform wind speed distribution.

[0138] As described above, according to the air supply device 100 using the plurality of air guiding members 1 of this application example, the following effects can be obtained.

[0139] (8) The air supply device 100 includes a plurality of air guiding members 1 and a blower 103 that supplies air to each of the plurality of air guiding members 1. The plurality of air guiding members 1 are arranged side by side with a gap such that the lower surfaces of the blowout openings 3 of the plurality of air guiding members 1 are located on the same plane, and are configured such that the guiding air flow AF2 guided by the blown air flow AF1 blown out from the blowout opening 3 passes through the gap.

[0140] Thereby, the air supply device 100 can generate a uniform air flow AF3 (surface air flow) with no deviation in wind speed.

[0141] (9) In addition, the plurality of air guiding members 1 may be installed on the wall surface 101, and the suction port 102, which is an opening for taking air into the interior, may be installed at a position below a height of 130 cm from the ground in the area of the wall surface 101.

[0142] According to this structure, the suction port 102 can be further arranged at a position closer to the ground side than the head of a human body sitting in the indoor space, so that efficient air circulation or air conditioning can be carried out.

[0143] (5. Modification example)

[0144] In the air supply device 100 using multiple air guiding members 1 of the application example, eight air guiding members 1 are arranged side by side. However, in order to extend the length of the air guiding member 1 in the long side direction, as each air guiding member constituting the multiple air guiding members 1, a connecting air guiding member 1x that connects multiple (for example, two) air guiding members 1 can also be used to form the air passage 4 (hollow space 2).

[0145] Hereinafter, Figure 8A and Figure 8B will be used to illustrate such a connecting air guiding member 1x as a modification example.

[0146] Figure 8A is a schematic perspective view of the connecting air guiding member 1x that connects two air guiding members 1a and 1b, Figure 8B is an enlarged perspective view of the connecting portion in the connecting air guiding member 1x.

[0147] As Figure 8A shown, the connecting air guiding member 1x is formed by connecting the end portion 70a of the air guiding member 1a and the end portion 70b of the air guiding member 1b that face each other in the long side direction (x direction). The air guiding members 1a and 1b basically have the same structure as the air guiding member 1 of the embodiment. In Figure 8A example, the end portion of the air guiding member 1a opposite to the end portion 70a is closed by the top plate 60a, and the air guiding member 1b does not have the top plate 60 and is configured to supply air from the end portion opposite to the end portion 70b.

[0148] More specifically, as Figure 8B shown, the connecting air guiding member 1x is provided with a connecting member 71b that protrudes in the long side direction from the inside of the end portion 70b at the end portion 70b of the air guiding member 1b. By inserting and connecting this connecting member 71b to the inside of the end portion 70a of the air guiding member 1a, the air guiding members 1a and 1b are connected and fixed. Thereby, the hollow spaces 2 are also connected and communicated with each other. In addition, the structure of the connecting member is not limited to the above example, and a structure that connects the end portions from the outside or other various structures can be used.

[0149] Here, the end portion 70a of the air guide member 1a corresponds to the "end portion in the long side direction of one air guide member component composed of the first outer air guide member and the second outer air guide member" in the claims, and the end portion 70b of the air guide member 1b corresponds to the "end portion in the long side direction of the other air guide member component". That is, it can also be said that in the connecting air guide member 1x, the end portion in the long side direction of one of the first outer air guide member and the second outer air guide member is configured to be connectable to the end portion in the long side direction of the other of the first outer air guide member and the second outer air guide member via a connecting member.

[0150] As described above, the connecting air guide member 1x according to the modification example can achieve the following effects.

[0151] (10) The connecting air guide member 1x may also be configured such that the end portion 70a of the air guide member 1a (the end portion in the long side direction of one air guide member component composed of the first outer air guide member 10 and the second outer air guide member 20) is connected to the end portion 70b of the other air guide member 1b (the end portion in the long side direction of the other air guide member component) via the connecting member 71b.

[0152] Thus, further, in the basic drawing of one air guide member, air guide members having different lengths in the long side direction can be formed, and the length can be freely set according to the installation environment of each air guide member. At this time, if an air guide member with a length that can be manufactured in one time using a sheet metal part is used for connection, a connecting air guide member 1x with a required length can be manufactured at low cost.

[0153] (11) The connecting member 71b may also be a member that is provided at the end portion 70a in the long side direction of one air guide member component, protrudes in the long side direction, and is inserted into the inside of the end portion 70b of the other air guide member component.

[0154] According to such a structure, a connecting air guide member 1x with good design can be formed with a simple structure.

[0155] As described above, as examples of the technology disclosed in the present application, the embodiments, application examples, and modification examples have been described. However, the technology in the present invention is not limited to these, and can also be applied to forms with changes, replacements, additions, or omissions, etc. In addition, the constituent elements described in the above embodiments, application examples, and modification examples can be combined to form a new embodiment. Furthermore, the above embodiments are used to illustrate the technology in the present invention, so various changes, replacements, additions, and omissions, etc. can be made within the scope of the claims or their equivalents.

[0156] Industrial applicability

[0157] The present invention can be applied to an air guide member that alleviates the complexity of the shape and has a risk of increased noise in the air guide member that blows out an air flow.
