The second wind direction plate 22 is positioned on the back side of the main body case 3, and the front side of the main body case 3 is moved in the elevation direction from the second top surface 29 of the main body case 3 by the second rotation means 26. It can rotate to an angle of 2.

  The feature of the present embodiment is that the top surface of the main body case 3 is constituted by the first top surface 28 and the second top surface 29 parallel to the horizontal plane, and the first wind direction on the first top surface 28 The adjustment means 8 is provided with the second wind direction adjustment means 9 on the second top surface 29, and the second top surface 29 is located at a lower height than the first top surface 28.

  That is, the air taken in from the air inlet 1 by the air blowing means 5 is blown to the air blowing port 2 through the air purifying means 4, and the wind direction is adjusted by the first wind direction adjusting means 8 and the second wind direction adjusting means 9. Change it. The first wind direction adjusting means 8 is located on the first top surface 28 on the front side of the main body case 3 and blows from the first top surface 28 to the front side of the main case 3 at a first angle in the elevation direction. To change the angle of the first wind direction plate 17 so that the second wind direction adjusting means 9 is located on the second top surface 29 on the back side of the main body case 3 and the elevation angle from the second top surface 29 The angle of the second wind direction plate 22 is changed so as to blow air to the front side of the main body case 3 at a second angle in the direction.

  Here, by making the first top surface 28 and the second top surface 29 having the first wind direction adjustment means 8 and the second wind direction adjustment means 9 parallel to the horizontal plane, the first wind direction adjustment means 8 The first wind direction plate 17 and the second wind direction are compared with the case where the top surface having the second wind direction adjusting means 9 is configured by an inclined surface that inclines upward as going from the back to the front of the body case 3 The angle of the plate 22 can be made close to horizontal. As a result, the blowing angle of the blowing air from the blowing port 2 becomes smaller in the elevation angle direction, and the flow of air flowing into the air intake port 1 of the main body by lowering the center of the swirl of circulating air flow indoors by approaching horizontal. The height above the floor is smaller. This makes it possible to increase the air flow and the wind speed on the floor.

  In addition, the top surface of the main body case 3 is configured by the first top surface 28 and the second top surface 29, and the second top surface 29 is positioned at a lower height than the first top surface 28. Compared with the case where the first wind direction adjusting means 8 and the second wind direction adjusting means 9 exist on the same plane, the blowing width in the vertical direction of the blowing wind from the air blowing port is narrower and the wind speed becomes faster, A stronger circulating air flow can be created in the room, and the effect that the air velocity and the air flow rate of the air flowing into the air intake can be increased over the indoor floor can be obtained.

  In addition, the casing air passage portion 16 is configured to be inclined from the back side to the front side in the body case 3, and the dimension in the front-rear direction of the body case 3 of the first wind direction plate 17 is the body case of the second air direction plate 22. It is a configuration smaller than the dimension in the front-rear direction in 3.

  As described above, since the fan unit 12 rotates about the shaft unit 15 which is an axis extending in the horizontal direction by the motor unit 11, the air sucked from the suction port 13 is substantially vertical in the casing air passage unit 16. It is blown up upwards. Here, since the casing air passage portion 16 is inclined from the back side to the front side in the body case 3, the amount of air passing through the front side is reduced in the casing air passage portion 16 compared to the back side in the body case 3 , The amount of air passing through the back side increases. That is, the second wind direction plate 22 needs to change the wind direction of the wind having a faster wind speed than the first wind direction plate 17. In the dimension of the wind direction plate, by increasing the width in the front-rear direction in the main body case 3 along the blowing direction, the amount of wind leaking upward from the second wind direction plate 22 is reduced, and the wind direction is changed forward. The amount of air flow can be increased. As a result, the center of the circulation airstream in the room is lowered by the center of the angle from which the wind blows out horizontally, and the height of the airstream flowing into the inlet 1 from the floor becomes smaller, and the air volume and the wind speed on the floor Can be increased.

  As shown in FIG. 4, the side surface of the main body case 3 is configured to have a notch portion 30 in alignment with the first top surface 28 and the second top surface 29.

  Specifically, when viewed from the side of the main body case 3, the top surface of the main body case 3 is not flat but looks like a stair with two horizontal surfaces. The notched portion is a notch 30. That is, when viewed from the side of the main body case 3, when the second wind direction plate 22 is opened, the second wind direction plate 22 can be seen through the notch 30. Further, when the first wind direction plate 17 and the second wind direction plate 22 are closed, they become flush with the respective horizontal planes.

  Here, by having the notched portion 30, the top surface having the first wind direction adjusting means 8 and the second wind direction adjusting means 9 is configured as an inclined face which inclines upward from the back to the front of the main body case 3. As compared with the structure without the notched portion, the opening degree of the second wind direction plate 22 is expanded from the second top surface 29 in the side direction. Thus, the wind whose direction can be changed by the second wind direction plate 22 through the casing air passage portion 16 can be changed not only in the forward direction of the main body case 3 but also in the lateral direction. As a result, not only a strong air flow in the forward direction of the main body case 3 but also an air flow spreading in the diagonally forward direction with respect to the left and right direction of the main body is generated. Thus, the air volume and the wind speed on the floor of the air flow flowing into the air inlet 1 can be further increased.

  As shown in FIG. 4, a third top surface 31 having a substantially flat area is provided in front of the first wind direction adjusting means 8 provided on the first top surface 28. Since the wind passing through the front side of the main body case 3 in the casing air passage 16 blows out along the third top 31 by the Coanda effect of the third top 31, the blowout from the air outlet 2 The angle is smaller in the elevation direction.

  As a result, since the vertical height of the air flow flowing into the main body intake 1 on the floor can be reduced, the wind speed of the air flow flowing into the intake 1 on the floor can be further increased.

  As shown in FIG. 2, an intake position adjustment plate 32 is provided on the front surface of the main body case 3. The intake position adjustment plate has a structure capable of moving in the front and rear direction separately at the upper and lower portions. It is a structure fixed in position and opening only the lower part in the front direction. Thus, the position of the intake port can be restricted downward as compared with the case where the air is taken from the entire front of the main body case 3. As a result, since the vertical height of the air flow flowing into the main body air intake port 1 on the floor can be reduced, the air velocity of the air flow flowing into the air intake port 1 on the floor can be further increased.

  The air purification device according to the present invention is expected to be used as an air purification device or the like for home use or business use.
