[0015] Figure 3B This is a diagram showing the structure of the air cleaning device involved in Modification Example 2. Detailed Implementation

[0016] The embodiments of the present disclosure will now be described with reference to the accompanying drawings. Furthermore, the following embodiments are merely examples embodying the present disclosure and do not limit the technical scope of the disclosure. Additionally, the figures described in the embodiments are schematic diagrams, and the size and thickness ratios of the constituent elements in each figure may not reflect actual dimensional ratios.

[0017] Figure 1A , Figure 1B as well as Figure 1C The structure of the air cleaning device 100 is shown. Figure 1A This is a perspective view showing the appearance of the air purifying device 100. The main body housing 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 rearward direction, and the direction from the rear surface 14 toward the front surface 12 is the forward direction. The direction from the first side surface 16 toward the second side surface 18 is the leftward direction, and the direction from the second side surface 18 toward the first side surface 16 is the rightward 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.

[0018] 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. Here, the width of the front surface 12, rear surface 14, upper surface 20, and lower surface 22 in the left-right direction is shorter than the width of the first side surface 16, second side surface 18, upper surface 20, and lower surface 22 in the front-back direction. Furthermore, the width of the front surface 12, rear surface 14, upper surface 20, and lower surface 22 in the left-right direction is shorter than the height of the front surface 12, rear surface 14, first side surface 16, and second side surface 18 in the vertical direction. As a result, the main body shell 10 has a thin shape in the left-right direction.

[0019] A front surface intake 30 is provided on the front surface 12 of the main housing 10. A side intake 32 is provided on at least one of the first side 16 or the second side 18 of the main housing 10, for example, on the lower part of the first side 16. An exhaust outlet 34 is provided on the upper surface 20 of the main housing 10. The front surface intake 30, the side intake 32, and the exhaust outlet 34 are openings. Therefore, the air purifier 100 connects its interior and exterior via the front surface intake 30, the side intake 32, and the exhaust outlet 34.

[0020] Figure 1B It shows from Figure 1A A perspective view of the internal structure of the air purification device 100 after removing the first side panel 16. Figure 1C yes Figure 1B Sectional view A-A'. In Figure 1C The first side surface 16 is shown. A front surface side air cleaning section 40 is disposed inside the main body housing 10, behind the front surface intake 30. Additionally, a lower surface side air cleaning section 42 is disposed inside the main body housing 10, at the upper edge of the side intake 32 and above the lower surface 22. The lower surface side air cleaning section 42 is disposed above the lower surface 22 and is positioned higher than the upper edge of the side intake 32. Both the front surface side air cleaning section 40 and the lower surface side air cleaning section 42 have a plate shape. The front surface side air cleaning section 40 is positioned opposite the front surface 12, and the lower surface side air cleaning section 42 is positioned opposite the lower surface 22. The front surface side air cleaning section 40 and the lower surface side air cleaning section 42 are filters for dust removal. Since known technologies can be used for dust removal filters, their description is omitted here.

[0021] Inside the main housing 10, a receiving space 50 is formed, surrounded by a front surface side air cleaning section 40, a lower surface side air cleaning 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 within the receiving space 50. The air supply section 60 includes: a housing 62, a first air intake 64, a second air intake 66, a motor 68, blades 70, and an exhaust outlet 72. The housing 62 is a hollow frame having a cylindrical portion and a foot portion. The cylindrical portion has a left-right axis, and the foot portion extends upward from a portion of the side of the cylindrical portion.

[0022] A first air intake 64 is provided on the surface of the cylindrical portion of the housing 62 on the first side 16, and a second air intake 66 is provided on the surface of the cylindrical portion of the housing 62 on the second side 18. That is, the first air intake 64 faces the first side 16, and the second air intake 66 faces the second side 18. Both the first air intake 64 and the second air intake 66 are open. Therefore, the interior and exterior of the housing 62 are connected via the first air intake 64 and the second air intake 66.

[0023] Inside the cylindrical portion of the housing 62, a motor 68 and multiple blades 70 are housed. One example of the multiple blades 70 is a multi-blade fan. The motor 68 is fixed to the housing 62 with mounting screws or the like and has an output shaft extending in the left-right direction. The blades 70 are 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 portion of the foot portion of the housing 62. The outlet 72 is connected to the air outlet 34 on the upper surface 20.

[0024] When the blades 70 rotate due to the operation of the motor 68, air outside the main housing 10 is drawn into the receiving space 50 through the front surface intake port 30 and the front surface side air cleaning section 40, and is also drawn into the receiving space 50 through the side intake port 32 and the lower surface side air cleaning section 42. The air drawn into the receiving space 50 is drawn into the interior of the housing 62 through the first intake port 64 and the second intake port 66, and is blown out of the main housing 10 through the exhaust port 72 and the blowout port 34.

[0025] Within the main housing 10, not only is a front surface air cleaning section 40 provided for rearward airflow, but a lower surface air cleaning section 42 is also provided for upward airflow, thus maintaining dust collection efficiency. Furthermore, no filter is provided within the main housing 10 for left-right airflow, thus making the main housing 10 thinner in the left-right direction. Here, by making the cross-sectional airflow area of ​​the lower surface air cleaning section 42 larger than the opening area of ​​the side intake 32, the pressure loss of the air flowing into the main housing 10 is reduced.

[0026] (Variation Example 1)

[0027] Figure 2 The structure of the air cleaning device 100 involved in Modification 1 is shown. Figure 2 Is with Figure 1C A cross-sectional view in the same direction. The lower surface side air cleaning section 42 is inclined relative to the lower surface 22. In particular, the height of the first side 16 side of the lower surface side air cleaning section 42 is different from the height of the second side 18 side of the lower surface side air cleaning section 42. For example, the height of the first side 16 side of the lower surface side air cleaning section 42 is lower than the height of the second side 18 side of the lower surface side air cleaning section 42. Furthermore, the height relationship of the lower surface side air cleaning section 42 in the left-right direction can also be reversed.

[0028] (Variation Example 2)

[0029] Figure 3A , Figure 3B The structure of the air cleaning device 100 involved in Modification Example 2 is shown. Figure 3A Is with Figure 1B 3D diagrams in the same orientation Figure 3B Is with Figure 1C Sectional views in the same direction. Additionally, Figure 3B yes Figure 3A The B-B' cross-sectional view shows that the height of the front surface 12 side of the lower surface air cleaning section 42 differs from the height of the rear surface 14 side. For example, the height of the front surface 12 side of the lower surface air cleaning section 42 is higher than the height of the rear surface 14 side. Furthermore, the height relationship of the lower surface air cleaning section 42 in the vertical direction can also be reversed.

[0030] According to this embodiment, a front surface side air cleaning section 40 is disposed on the rear side of the front surface intake 30 inside the main body housing 10, and a lower surface side air cleaning section 42 is disposed on the upper side of the lower surface 22 and the side intake 32, thus maintaining dust collection performance. Furthermore, by disposing of no other air cleaning sections inside the main body housing 10, the housing can be made thinner in the horizontal direction. Additionally, the cross-sectional airflow area of ​​the lower surface side air cleaning section 42 is larger than the opening area of ​​the side intake 32, thus reducing the pressure loss of the air flowing into the main body housing 10. Furthermore, since the lower surface side air cleaning section 42 is oriented opposite to the lower surface 22, the lower surface 22 side, which has not been used as an air cleaning section so far, is used as an air cleaning section, thereby eliminating the need for air cleaning sections on the first side surface 16 and the second side surface 18.

[0031] Furthermore, since the lower surface air cleaning section 42 is inclined relative to the lower surface 22, its cross-sectional area can be increased. Additionally, the increased cross-sectional area of ​​the lower surface air cleaning section 42 reduces pressure loss of air flowing into the main housing 10. Furthermore, because the height of the first side 16 of the lower surface air cleaning section 42 differs from the height of the second side 18, it can be inclined relative to the lower surface 22. Furthermore, because the height of the front surface 12 of the lower surface air cleaning section 42 differs from the height of the rear surface 14, it can be inclined relative to the lower surface 22.
