[0026] (Implementation Method 1)

[0027] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that the following embodiments are merely examples of embellishment of the present invention and do not limit the technical scope of the invention. Furthermore, the figures described in each embodiment are schematic diagrams, and the size and thickness ratios of the constituent elements in each figure may not necessarily reflect actual dimensional ratios.

[0028] Figure 1 , Figure 2 , Figure 3 This indicates the structure of the air purification device 100. Figure 1This is a perspective view showing the appearance of the air purifier 100. The main body casing 10 has a box shape and is surrounded by a front surface 12, a rear surface 14, a first side surface 16, a second side surface 18, an upper surface 20, and a lower surface 22. The direction from the front surface 12 toward the rear surface 14 is the rear direction, and the direction from the rear surface 14 toward the front surface 12 is the front direction. The direction from the first side surface 16 toward the second side surface 18 is the left direction, and the direction from the second side surface 18 toward the first side surface 16 is the right direction. The direction from the upper surface 20 toward the lower surface 22 is the downward direction, and the direction from the lower surface 22 toward the upper surface 20 is the upward direction. Therefore, the front surface 12 and the rear surface 14 are arranged opposite each other in the front-rear direction, the first side surface 16 and the second side surface 18 are arranged opposite each other in the left-right direction, and the upper surface 20 and the lower surface 22 are arranged opposite each other in the vertical direction.

[0029] The front surface 12, rear surface 14, first side surface 16, second side surface 18, upper surface 20, and lower surface 22 are each rectangular in shape. Here, the lateral width of the front surface 12, rear surface 14, upper surface 20, and lower surface 22 is shorter than the longitudinal width of the first side surface 16, second side surface 18, upper surface 20, and lower surface 22. Furthermore, the lateral width of the front surface 12, rear surface 14, upper surface 20, and lower surface 22 is shorter than the vertical height of the front surface 12, rear surface 14, first side surface 16, and second side surface 18. As a result, the main body shell 10 has a thin shape in the lateral direction.

[0030] A first front surface intake 30 is disposed on the front surface 12 of the main body housing 10. An exhaust outlet 34 is disposed on the upper surface 20 of the main body housing 10. The first front surface intake 30 and the exhaust outlet 34 are openings. Therefore, the air purifier 100 connects its interior to the exterior via the first front surface intake 30 and the exhaust outlet 34.

[0031] Figure 2 It means from Figure 1 A perspective view of the internal structure of the air purification device 100 with the first side 16 removed. Figure 3 yes Figure 2 AA section view. In Figure 3 The first side surface 16 is shown. A front surface side air purification unit 40 is disposed inside the main housing 10, behind the first front surface intake 30. The front surface side air purification unit 40 has a plate-like shape. The front surface side air purification unit 40 is positioned opposite the front surface 12. The front surface side air purification unit 40 is a dust removal filter. Since known technology can be used for dust removal filters, description is omitted here.

[0032] Inside the main body shell 10, a storage space 50 is formed, surrounded by a front surface air purification section 40, a lower surface 22, a rear surface 14, a first side surface 16, a second side surface 18, and an upper surface 20. An air supply section 60 is disposed in the storage space 50. The air supply section 60 includes a housing 62, a first air intake 64, a motor 68, a fan section 70, and an exhaust outlet 72. The housing 62 is a hollow frame having a cylindrical portion and leg portions. The cylindrical portion has a left-right axis, and the leg portions extend upwards from a portion of the side of the cylindrical portion.

[0033] A first air intake 64 is provided on the first side surface 16 of the cylindrical portion of the housing 62. That is, the first air intake 64 is opposite to the first side surface 16. The first air intake 64 is an opening. Therefore, the housing 62 connects its interior and exterior at the first air intake 64.

[0034] A motor 68 and a fan section 70 are housed inside the cylindrical portion of the housing 62. One example of the fan section 70 is a unilateral intake Sirocco fan.

[0035] The fan section 70 includes a main board section 70a and a first blade section 70b.

[0036] The main board portion 70a is circular in shape, with a bowl-shaped recess 70d in the center. The recess 70d is recessed from the center of the main board portion 70a toward the first air intake 64 in the housing 62. The motor 68 is disposed inside the recess 70d.

[0037] The first blade portion 70b is a slender plate shape with a roughly arc-shaped cross-section, and multiple blades are arranged in a ring shape on the periphery of one side of the main plate portion 70a (the side of the first air intake 64 of the housing 62).

[0038] The motor 68 is fixed to the housing 62 by mounting screws or the like, and has an output shaft extending in the left-right direction. A fan 70 is mounted on the output shaft of the motor 68. An outlet 72, serving as an opening for the housing 62, is provided on the upper side of the leg portion of the housing 62. The outlet 72 is connected to the blow-out port 34 on the upper surface 20.

[0039] When the fan unit 70 rotates due to the operation of the motor 68, air outside the main body housing 10 is drawn into the storage space 50 through the first front surface intake port 30 and the front surface side air purification unit 40. The air drawn into the storage space 50 is drawn into the interior of the housing 62 through the first air intake port 64 and blown out of the main body housing 10 through the exhaust port 72 and the blowout port 34.

[0040] In addition, no filter is provided inside the main body housing 10 to allow air to pass through in the left and right directions, so the main body housing 10 is thin in the left and right directions.

[0041] In addition, a first rectifier 80 is provided at the first air intake 64 of the housing 62 in the air supply section 60. Figure 4 This is a front view showing the internal structure of the air purifier 100. Additionally, Figure 4 The structure of the first rectifier 80 is shown. The first rectifier 80 has a plurality of cylindrical first cylindrical rectifiers 82 arranged concentrically with respect to the central axis of the circular first intake port 64. Specifically, the first cylindrical rectifiers 82 are divided into a plurality of equal intervals with respect to the radius of the circle of the first intake port 64. The length of the first cylindrical rectifier 82 in the central axis direction is equal to the wall thickness of the first intake port 64. The surface of the housing 62 including the first side surface 16 of the first intake port 64 is on the same plane as the end surface of the first side surface 16 of the first cylindrical rectifier 82.

[0042] Therefore, the first intake port 64 is subdivided by multiple first cylindrical rectifiers 82. Air passing through the first front surface intake port 30 and the front surface side air purification section 40 is less likely to flow into the area on the front surface 12 side (front side of the first intake port 64) when passing through the first intake port 64. As a result, air flow into the area on the front surface 12 side of the first intake port 64 is suppressed. Air flowing towards the first intake port 64 from a direction perpendicular to the central axis of the first intake port 64 can be delivered from the first intake port 64 as a whole to the fan section 70 within the air supply section 60 via the first cylindrical rectifiers 82, thus suppressing performance degradation.

[0043] Furthermore, the first rectifier 80 has a plurality of linear first radial rectifiers 84 arranged radially relative to the central axis of the circular first intake port 64. Specifically, the first radial rectifiers 84 are divided into a plurality of equal intervals relative to the circumference of the circle of the first intake port 64. Moreover, the first radial rectifiers 84 are divided into a plurality of equal intervals relative to the circumference of the circle of the first intake port 64 in a range that is outside half the radius of the circle of the first intake port 64. The length of the first intake port 64 in the central axis direction of the first radial rectifier 84 is equal to the wall thickness of the first intake port 64. The surface of the housing 62 including the first intake port 64 and the first cylindrical rectifier 82, and the end face of the first side surface 16 of the first radial rectifier 84 are on the same plane. It should be noted that the distance between adjacent first cylindrical rectifiers 82 is shorter than the distance between adjacent first radial rectifiers 84. The opening surrounded by the adjacent first cylindrical rectifier 82 and the adjacent first radial rectifier 84 is an elongated shape that is longer in the arc direction of the first cylindrical rectifier 82.

[0044] Therefore, the first intake port 64 is subdivided by a plurality of first cylindrical rectifiers 82 and a plurality of first radial rectifiers 84. As a result, air passing through the first front surface intake port 30 and the front surface side air purification section 40 is less likely to flow into the area on the front surface 12 side of the first intake port 64 when passing through the first intake port 64. Consequently, it is believed that for air flowing towards the first intake port 64 from a direction perpendicular to the central axis of the first intake port 64, the first cylindrical rectifiers 82 and the first radial rectifiers 84 can suppress its deflection towards the front surface 12 side of the first intake port 64, thereby ensuring that air is delivered from the first intake port 64 to the fan section 70 within the air supply section 60, and suppressing performance degradation.

[0045] Here, it is assumed that the first air intake 64 is divided into three parts in the front-rear direction of the main body shell 10. That is, the portion of the first air intake 64 on the front surface 12 side is designated as the first air intake front surface portion 64a, the portion of the first air intake 64 on the rear surface 14 side is designated as the first air intake rear surface portion 64b, and the portion between the front surface 12 side and the rear surface 14 side is designated as the first air intake central portion 64c. In the opening surrounded by the adjacent first cylindrical rectifier 82 and the adjacent first radial rectifier 84, the first air intake central portion 64c is larger than the first air intake front surface portion 64a in terms of the dimension of the main body shell 10 in the direction from the front surface 12 side to the rear surface 14 side (the direction of air flow) of the main body shell 10. Here, the air passing through the first front surface intake 30 and the front surface side air purification section 40 flows from the front surface 12 side to the rear surface 14 side of the main body shell 10 between the surface of the shell 62 having the first air intake 64 and the first side surface 16 of the main body shell 10. Regarding the air flowing toward the housing 62, the pressure loss is smaller when air flows into the housing 62 through the opening in the central portion 64c of the first air intake compared to air flowing into the housing 62 through the opening in the front surface portion 64a of the first air intake, thus it is considered to flow more easily. As a result, air flowing toward the first air intake 64 in a direction perpendicular to the central axis of the first air intake 64 and from the front surface 12 side to the rear surface 14 side of the main housing 10 is suppressed by the first cylindrical rectifier 82 and the first radial rectifier 84, preventing it from being deflected toward the front surface 12 side of the first air intake 64, and can be delivered from the first air intake 64 to the fan portion 70 in the air supply portion 60. Therefore, it is believed that performance degradation can be suppressed.

[0046] (Implementation Method 2)

[0047] The same reference numerals are used for the same components as in Embodiment 1, and detailed descriptions thereof are omitted. Figure 5This is a perspective view showing the appearance of the air purifier 110. A first front surface intake 30 and a second front surface intake 31 are provided on the front surface 12 of the main housing 10. The first front surface intake 30 is positioned above the second front surface intake 31. An exhaust outlet 34 is provided on the upper surface 20 of the main housing 10. The first front surface intake 30, the second front surface intake 31, and the exhaust outlet 34 are openings. Therefore, the air purifier 110 connects its interior to its exterior via the first front surface intake 30, the second front surface intake 31, and the exhaust outlet 34.

[0048] Figure 6 It means from Figure 5 A perspective view of the internal structure of the air purification device 110 with the first side 16 removed. Figure 7 It means from Figure 5 A perspective view of the internal structure of the air purification device 110 with the second side 18 removed. Figure 8 yes Figure 6 BB cross-sectional view. Figure 9 yes Figure 6 The CC section view. It should be noted that, in Figure 8 , Figure 9 The first side surface 16 is shown. A front surface air purification section 40 is disposed inside the main body housing 11, behind the first front surface intake 30. Additionally, a lower surface air purification section 42 is disposed inside the main body housing 11, at the upper edge of the second front surface intake 31 and above the lower surface 22. The lower surface air purification section 42 is disposed above the lower surface 22 and is positioned above the upper edge of the second front surface intake 31. Both the front surface air purification section 40 and the lower surface air purification section 42 have a plate-like shape, with the front surface air purification section 40 facing opposite to the front surface 12 and the lower surface air purification section 42 facing opposite to the lower surface 22. The front surface air purification section 40 and the lower surface air purification section 42 are filters for dust removal. Since known technologies can be used for dust removal filters, their description is omitted here.

[0049] Inside the main body shell 11, a storage space 50 is formed, surrounded by a front surface air purification section 40, a lower surface air purification section 42, a rear surface 14, a first side surface 16, a second side surface 18, and an upper surface 20. An air supply section 60 is disposed in the storage space 50. The air supply section 60 includes a housing 63, a first air intake 64, a second air intake 66, a motor 68, a fan section 71, and an exhaust outlet 72. The housing 62 is a hollow frame having a cylindrical portion and leg portions. The cylindrical portion has a left-right axis, and the leg portions extend upwards from a portion of the side of the cylindrical portion.

[0050] A first air intake 64 is provided on the first side 16 of the cylindrical portion of the housing 63, and a second air intake 66 is provided on the second side 18 of the cylindrical portion of the housing 63. That is, the first air intake 64 is opposite to the first side 16, and the second air intake 66 is opposite to the second side 18. Both the first air intake 64 and the second air intake 66 are open. Therefore, the interior of the housing 63 is connected to the exterior via the first air intake 64 and the second air intake 66.

[0051] A motor 68 and a plurality of fan sections 71 are housed inside the cylindrical portion of the housing 63. One example of the fan section 71 is a Sirocco fan with intake from both sides.

[0052] The fan section 71 includes a main board section 71a, a first blade section 71b, and a second blade section 71c.

[0053] The main board portion 71a is circular in shape and has a bowl-shaped recess 71d in the center. The recess 71d is recessed from the center of the main board portion 71a toward the first air intake 64 in the housing 63. A portion of the motor 68 is disposed inside the recess 71d.

[0054] The first blade portion 71b is a slender plate with a roughly arc-shaped cross-section, and multiple blades are arranged in a ring around the periphery of one side of the main plate portion 71a (the side of the first air intake 64 of the housing 63).

[0055] The second blade portion 71c is a slender plate with a roughly arc-shaped cross-section, and multiple blades are arranged in a ring around the periphery of the other side of the main plate portion 71a (the side of the second air intake 66 of the housing 63).

[0056] The motor 68 is fixed to the housing 63 by mounting screws or the like, and has an output shaft extending in the left-right direction. A fan 71 is mounted on the output shaft of the motor 68. An outlet 72, serving as an opening for the housing 63, is provided on the upper side of the leg portion of the housing 63. The outlet 72 is connected to the blow-out port 34 on the upper surface 20.

[0057] When the fan unit 71 rotates due to the operation of the motor 68, air outside the main body housing 11 is drawn into the storage space 50 through the first front surface intake port 30 and the front surface side air purification unit 40, and is also drawn into the storage space 50 through the second front surface intake port 31 and the lower surface side air purification unit 42. Air inside the storage space 50 is drawn into the interior of the housing 63 through the first air intake port 64 and the second air intake port 66, and is blown out of the main body housing 11 through the exhaust port 72 and the blowout port 34.

[0058] Inside the main body casing 11, not only is a front surface-side air purification section 40 provided for air to pass in the rearward direction, but a lower surface-side air purification section 42 is also provided for air to pass in the upward direction, thus maintaining dust collection performance. Furthermore, no filter is provided inside the main body casing 11 for air to pass in the left-right direction, thus making the main body casing 11 thinner in the left-right direction. Here, the cross-sectional airflow area of ​​the lower surface-side air purification section 42 is larger than the opening area of ​​the second front surface intake 31, thereby reducing pressure loss.

[0059] According to this embodiment, a front surface-side air purification unit 40 is disposed on the inner side of the main body shell 11, behind the first front surface intake 30, and a lower surface-side air purification unit 42 is disposed on the lower surface 22 and above the second front surface intake 31, thus maintaining dust collection performance. Furthermore, by disposing of the front surface-side air purification unit 40 on the inner side of the main body shell 11, behind the first front surface intake 30, and the lower surface-side air purification unit 42 on the lower surface 22 and above the second front surface intake 31, and omitting other air purification units, the frame can be made thinner in the horizontal direction. Additionally, the cross-sectional airflow area of ​​the lower surface-side air purification unit 42 is larger than the opening area of ​​the second front surface intake 31, thus reducing pressure loss. Furthermore, the lower surface-side air purification unit 42 is positioned opposite the lower surface 22, thus utilizing the lower surface 22 side, which was not previously used as an air purification unit, as an air purification unit, eliminating the need to provide air purification units on the first side surface 16 and the second side surface 18.

[0060] In addition, a first rectifier 80 is provided at the first air intake 64 of the housing 63 in the air supply section 61, and a second rectifier 86 is provided at the second air intake 66 of the housing 63 in the air supply section 61.

[0061] Thus, the first air intake 64 and the second air intake 66 are subdivided. When the air passing through the first front surface intake 30 and the front surface side air purification unit 40 passes through the first air intake 64 and the second air intake 66, the first rectifier 80 and the second rectifier 86 can suppress the deviation of the air from the direction perpendicular to the central axis of the first air intake 64 and the central axis of the second air intake 66, and deliver the air to the fan unit 71 in the air supply unit 61, thereby suppressing performance degradation.

[0062] The first rectifier section 80 has a plurality of cylindrical first cylindrical rectifier sections 82 arranged concentrically with respect to the central axis of the circular first air intake 64. Specifically, the first cylindrical rectifier sections 82 are divided into a plurality of equal intervals with respect to the radius of the circle of the first air intake 64. The length of the first cylindrical rectifier section 82 in the direction of the central axis is equal to the wall thickness of the first air intake 64, and the surface of the housing 63 in the air supply section 61 including the first side surface 16 of the first air intake 64 is on the same plane as the end face of the first side surface 16 of the first cylindrical rectifier section 82.

[0063] Therefore, by means of multiple first cylindrical rectifiers 82, the first air intake 64 is subdivided, making it difficult for air passing through the first front surface intake 30 and the front surface side air purification section 40 to flow into the area on the front surface 12 side of the first air intake 64. As a result, it is believed that the flow of air into the area on the front surface 12 side of the first air intake 64 can be suppressed, and air arriving at the first air intake 64 from a direction perpendicular to the central axis of the first air intake 64 can be transported from the first air intake 64 as a whole to the fan section 71 in the air supply section 61 by the first cylindrical rectifiers 82, thus suppressing performance degradation.

[0064] Furthermore, the first rectifier 80 has a plurality of linear first radial rectifiers 84 arranged radially relative to the central axis of the circular first intake port 64. Specifically, the first radial rectifiers 84 are divided into a plurality of equal intervals relative to the circumference of the circle of the first intake port 64, and are also divided into a plurality of equal intervals relative to the circumference of the circle of the first intake port 64 within a range that is half the radius outward. The length of the first intake port 64 in the central axis direction of the first radial rectifier 84 is equal to the wall thickness of the first intake port 64, and the surface of the housing 63 of the air supply section 61 including the first intake port 64 and the first side surface 16 of the first cylindrical rectifier 82 is on the same plane as the end surface of the first side surface 16 of the first radial rectifier 84. It should be noted that the distance between adjacent first cylindrical rectifiers 82 is shorter than the distance between adjacent first radial rectifiers 84. The opening surrounded by the adjacent first cylindrical rectifier 82 and the adjacent first radial rectifier 84 is an elongated shape that is longer in the arc direction of the first cylindrical rectifier 82.

[0065] Therefore, the first intake port 64 is subdivided by multiple first cylindrical rectifiers 82 and multiple first radial rectifiers 84, making it difficult for air passing through the first front surface intake port 30 and the front surface side air purification section 40 to flow into the area on the front surface 12 side of the first intake port 64. As a result, it is believed that the first cylindrical rectifiers 82 and the first radial rectifiers 84 can suppress the deflection of air from a direction perpendicular to the central axis of the first intake port 64 towards the front surface 12 side of the first intake port 64, and deliver this air from the first intake port 64 to the fan section 71 in the air supply section 61, thereby suppressing performance degradation.

[0066] Here, it is assumed that the first air intake 64 is divided into three parts in the front-rear direction of the main body shell 11. That is, the portion of the first air intake 64 on the front surface 12 side is designated as the first air intake front surface portion 64a, the portion of the first air intake 64 on the rear surface 14 side is designated as the first air intake rear surface portion 64b, and the portion between the front surface 12 side and the rear surface 14 side is designated as the first air intake central portion 64c. Although the details are not yet clear, regarding the size of the opening surrounded by the adjacent first cylindrical rectifier 82 and the adjacent first radial rectifier 84 in the direction from the front surface 12 side to the rear surface 14 side of the main body shell 11 (the direction of airflow), the first air intake central portion 64c is larger than the first air intake front surface portion 64a. Here, air passing through the first front surface intake 30 and the front surface side air purification section 40 flows from the front surface 12 side to the rear surface 14 side of the main body shell 11 between the surface of the housing 63 having the first intake 64 and the first side surface 16 of the main body shell 11. Regarding the air flowing inside the housing 63, the pressure loss is smaller when flowing into the housing 63 from the opening of the front surface portion 64a of the first intake 64 compared to when it flows into the housing 63, so it is considered to flow more easily. As a result, air flowing towards the first intake 64 in a direction perpendicular to the central axis of the first intake 64 and from the front surface 12 side to the rear surface 14 side of the main body shell 11 is suppressed by the first cylindrical rectifier 82 and the first radial rectifier 84 to deflect towards the front surface 12 side of the first intake 64, and can be delivered from the first intake 64 to the fan section 71 in the air supply section 61. Therefore, it is considered that performance degradation can be suppressed.

[0067] The second rectifier section 86 has a plurality of cylindrical second cylindrical rectifier sections 88 arranged concentrically with respect to the central axis of the circular second air intake 66. Specifically, the second cylindrical rectifier sections 88 are divided into a plurality of equal intervals with respect to the radius of the circle of the second air intake 66. The length of the second cylindrical rectifier section 88 in the central axis direction is equal to the wall thickness of the second air intake 66. The surface of the housing 63 in the air supply section 61 that includes the second side surface 18 of the second air intake 66 is on the same plane as the end surface of the second side surface 18 of the second cylindrical rectifier section 88.

[0068] Therefore, the second air intake 66 is subdivided by multiple second cylindrical rectifiers 88, making it difficult for air passing through the first front surface intake 30 and the front surface side air purification section 40 to flow into the area on the front surface 12 and the area on the lower surface 22 of the second air intake 66. As a result, it is believed that air flowing into the area on the front surface 12 and the lower surface 22 of the second air intake 66 can be suppressed, and air flowing towards the second air intake 66 in a direction perpendicular to the central axis of the second air intake 66 can be delivered from the second air intake 66 as a whole to the fan section 71 in the air supply section 61 through the second cylindrical rectifiers 88, thus suppressing performance degradation.

[0069] Furthermore, the second rectifier 86 has a plurality of linear second radial rectifiers 90 arranged radially relative to the central axis of the circular second intake port 66. Specifically, the second radial rectifiers 90 are divided into 16 equal parts at intervals relative to the circumference of the circle of the second intake port 66, and further divided into 32 equal parts at intervals relative to the circumference of the circle of the second intake port 66 in a range outside half the radius of the circle of the second intake port 66. The length of the second intake port 66 in the central axis direction of the second radial rectifier 90 is equal to the wall thickness of the second intake port 66, and the surface of the housing 63 of the air supply section 61 including the second side surface 18 of the second intake port 66 and the second cylindrical rectifier 88 is on the same plane as the end face of the second side surface 18 of the second radial rectifier 90. It should be noted that the distance between adjacent second cylindrical rectifiers 88 is shorter than the distance between adjacent second radial rectifiers 90. The opening surrounded by the adjacent second cylindrical rectifier 88 and the adjacent second radial rectifier 90 is a long, slender shape in the arc direction of the second cylindrical rectifier 88.

[0070] Therefore, the second intake port 66 is subdivided by multiple second cylindrical rectifiers 88 and multiple second radial rectifiers 90, making it difficult for air passing through the first front surface intake port 30 and the front surface side air purification section 40 to flow into the area on the front surface 12 side of the second intake port 66. As a result, it is believed that air flowing towards the second intake port 66 from a direction perpendicular to the central axis of the second intake port 66 can be suppressed from deflecting towards the front surface 12 side of the second intake port 66 by the second cylindrical rectifiers 88 and the second radial rectifiers 90, and is delivered from the second intake port 66 to the fan section 71 in the air supply section 61. Therefore, performance degradation can be suppressed.

[0071] Here, it is assumed that the second air intake 66 is divided into three parts in the front-rear direction of the main body shell 11. That is, the portion of the second air intake 66 on the front surface 12 side is designated as the front surface portion 66a, the portion of the second air intake 66 on the rear surface 14 side is designated as the rear surface portion 66b, and the portion between the front surface 12 side and the rear surface 14 side is designated as the central portion 66c. Although the details are not yet clear, regarding the size of the opening surrounded by the adjacent second cylindrical rectifier 88 and the adjacent second radial rectifier 90 in the direction from the front surface 12 side to the rear surface 14 side of the main body shell 11 (the direction of airflow), the central portion 66c of the second air intake is larger than the front surface portion 66a. Therefore, regarding the air flowing from the front surface 12 side to the rear surface 14 side of the main body housing 11 through the first front surface intake 30 and the front surface side air purification section 40, and between the surface of the housing 63 having the second intake 66 and the second side surface 18 of the main body housing 11, the pressure loss of the air flowing into the housing 63 from the opening of the front surface portion 66a of the second intake 66 is smaller, and therefore it is considered to flow more easily. As a result, the second cylindrical rectifier 88 and the second radial rectifier 90 can suppress the air flowing from the front surface 12 side to the rear surface 14 side of the main body housing 11 in a direction perpendicular to the central axis of the second intake 66 from being deflected towards the front surface 12 side of the second intake 66, and delivered from the second intake 66 to the fan section 71 in the air supply section 61. Therefore, it is considered that performance degradation can be suppressed.

[0072] In addition, an air direction changing section 92 is provided on the inner side of the main body shell 11 between the air purification section 40 and the air supply section 61 on the front surface side. Figure 9The structure of the airflow direction changing unit 92 is shown. The airflow direction changing unit 92 changes the airflow direction of the air passing through the front surface side air purification unit 40 to the first side surface 16 and the second side surface 18. The airflow direction changing unit 92 has multiple plate-shaped components. Specifically, the airflow direction changing unit 92 has multiple plate-shaped components extending obliquely from the rear surface 14 of the front surface side air purification unit 40 to the first side surface 16 in the range from the center of the first front surface intake 30 in the left-right direction to the first side surface 16, and multiple plate-shaped components extending obliquely from the rear surface 14 of the front surface side air purification unit 40 to the second side surface 18 in the range from the center of the first front surface intake 30 in the left-right direction to the second side surface 18.

[0073] Therefore, the airflow direction changing unit 92 changes the airflow direction of the air flowing rearward through the front surface side air purification unit 40 to the first side 16 and the second side 18. By making it easier for air to flow to the first air intake 64 and the second air intake 66, performance degradation can be suppressed.

[0074] Furthermore, a lower surface air purification section 42 is provided on the inner side of the main body shell 11, below the air supply section 61, and a second front surface intake 31 is provided on the front surface 12 of the main body shell 11, below the first front surface intake 30. Under the action of the air supply section 61, air drawn in from the second front surface intake 31 is delivered to the outlet 34 via the lower surface air purification section 42. Specifically, the lower surface air purification section 42 extends from the front surface 12 to the rear surface 14 on the inner side of the main body shell 11, and has a space 52 between it and the lower surface 22 of the main body shell 11. Under the action of the air supply section 61, air drawn in from the second front surface intake 31 is delivered to the lower surface air purification section 42 via the space 52.

[0075] Therefore, it not only has a front surface-side air purification section 40 that allows air to pass in the rearward direction, but also a lower surface-side air purification section 42 that allows air to pass in the upward direction, thus maintaining dust collection performance. Furthermore, since no filter for air to pass in the left-right direction is provided inside the main body casing 11, the main body casing 11 is thinner in the left-right direction. Here, the cross-sectional airflow area of ​​the lower surface-side air purification section 42 is larger than the opening area of ​​the second front surface intake 31, thereby reducing pressure loss.

[0076] Furthermore, the lower surface air purification section 42 extends from the front surface 12 to the rear surface 14 inside the main body housing 11, and has a space 52 between it and the lower surface 22 of the main body housing 11. Air drawn in from the second front surface intake 31 passes sequentially through the space 52 and the lower surface air purification section 42, and easily flows into the rear surface 14 side inside the main body housing 11. As a result, air drawn in from the second front surface intake 31 also easily flows into the housing 63 from the portion of the first intake port 64 on the rear surface 14 side, i.e., the first intake port rear surface portion 64b, and the portion of the second intake port 66 on the rear surface 14 side, i.e., the second intake port rear surface portion 66b.

[0077] The present invention has been described above based on various embodiments, but the present invention is not limited to any of the above embodiments, and it is easy to deduce that various modifications and variations can be made without departing from the spirit of the present invention.

[0078] The air purification device based on the present invention is expected to be used as an air purification device for home, office, etc.
