  The problem in the above conventional example is that when the wind speed of the suction airflow flowing into the air intake port on the floor is increased, the attraction of the airflow flowing into the air intake port of the main body by the blown airflow blown out from the air blowing port is increased.

  Compared with the one in which the blowing angle from the air outlet is large in the elevation direction, the one in which the blowing angle from the air outlet is small in the elevation direction is the center of the vortex of the circulating air flow in the room. Thus, the vertical height of the airflow flowing into the air inlet of the main body on the floor is reduced by lowering the center of the vortex of the circulating airflow. As a result, the wind speed of the airflow flowing into the intake port on the floor can be increased.

The first wind direction adjusting means 8 is located on the front surface side in the main body case 3 and changes the air direction so as to blow air from the horizontal plane to the front surface side in the main body case 3 at a first angle from the horizontal plane to the second wind direction. The adjusting means 9 is located on the back side of the main body case 3 and changes the air direction so that air is blown from the horizontal plane to the front side of the main body case 3 at a second angle in the elevation direction. Here, the first angle is the same as the second angle, and an air volume adjusting means is provided upstream of the first air direction adjusting means 8. By this air volume adjusting means, the air volume blown from the first wind direction adjusting means 8 becomes smaller than the air volume blown from the second wind direction adjusting means 9.

  Thus, the first angle is the same as the second angle, and the air volume adjusting means is provided on the upstream side of the first air direction adjusting means 8. The air volume that is blown from the first wind direction adjusting means 8 is smaller than the air volume that is blown from the second wind direction adjusting means 9 by the air volume adjusting means. The airflow blown from the adjusting means 8 can suppress the attraction of the airflow flowing into the intake port of the main body.

  Further, the amount of air blown from the second wind direction adjusting means 9 is larger than the amount of air blown from the first wind direction adjusting means 8. Thereby, although part of the airflow blown from the first wind direction adjusting means 8 is attracted by the airflow blown from the second wind direction adjusting means 9, the attraction of the airflow flowing into the intake port 1 of the main body is suppressed. can do.

  As shown in FIG. 3, the first wind direction adjusting means 8 includes a first wind direction plate 17 that is a horizontally long rectangular plate, and a shaft that allows the first wind direction plate 17 to rotate to the air outlet 2. It forms from the 1st axial support part 18 to support. The first shaft support portion 18 includes a first shaft portion 19 extending outward from the short side of the first wind direction plate 17 and a horizontal hole provided in the air blowing port 2. It consists of the 1st bearing part 20 in which the axial part 19 enters. First rotating means 21 for rotating the first wind direction plate 17 via the first shaft portion 19 is provided. The first wind direction plate 17 is located on the front surface side of the main body case 3, and the front surface side of the main body case 3 opens a first angle from the horizontal plane to the elevation angle direction by the first rotating means 21.

  The second wind direction adjusting means 9 includes a second wind direction plate 22 that is a horizontally long rectangular flat plate, and a second shaft support portion 23 that pivotally supports the second wind direction plate 22 to the air blowing port 2. Formed from. The second shaft support portion 23 includes a second shaft portion 24 extending outward from the short side of the second wind direction plate 22 and a horizontal hole provided in the air blowing port 2. It consists of the 2nd bearing part 25 in which the axial part 24 enters. Second rotating means 26 for rotating the second wind direction plate 22 via the second shaft portion 24 is provided. The second wind direction plate 22 is located on the front surface side of the main body case 3, and the front surface side of the main body case 3 opens a second angle from the horizontal plane to the elevation angle direction by the second rotating means 26. In addition, the dimension of the front-back direction in the main body case 3 of the 1st wind direction board 17 and the 2nd wind direction board 22 and the left-right direction is substantially the same.

  Note that the second angle may be larger than the first angle. Thereby, the attraction of the airflow blown from the first wind direction adjusting means 8 can be suppressed by the airflow blown from the second wind direction adjusting means 9.

  Centrifugal blow type air blowing means 5 has a scroll-shaped casing portion 10, a motor portion 11 fixed to the casing portion 10, and a shaft portion 15 that is a shaft extending horizontally by the motor portion 11. And a fan unit 12 that rotates in the direction. The casing unit 10 includes a suction port 13 on a side surface, a discharge port 14 on a top surface, and a casing air passage unit 16 between the discharge port 14 and the fan unit 12. Here, the air volume adjusting means is configured such that the casing air passage portion 16 is inclined from the back surface side to the front surface side in the main body case 3.

  Thus, since the fan part 12 rotates centering on the axial part 15 which is the axis | shaft extended in the horizontal direction by the motor part 11, the air suck | inhaled from the suction inlet 13 is substantially perpendicular | vertical in the casing air-path part 16. FIG. The air is blown upward. Here, since the casing air passage portion 16 is inclined from the back surface side to the front surface side in the main body case 3, a reduction in the amount of air blown from the air blowing port 2 is suppressed, and the main body case is formed in the casing air passage portion 16. As compared with the rear side in FIG. Thereby, the air volume blown from the first wind direction adjusting means 8 located on the front side in the main body case 3 is smaller than the air volume sent from the second wind direction adjusting means 9 located on the rear side in the main body case 3. . As a result, it is possible to suppress the attraction of the airflow flowing into the intake port 1 of the main body by the airflow blown from the first air direction adjusting means 8.

  Moreover, since the fan part 12 rotates centering around the axial part 15 which is the axis | shaft extended in the horizontal direction by the motor part 11, the air suck | inhaled from the suction inlet 13 in the casing air-path part 16 in the substantially perpendicular upper direction. Be blown. Here, since the casing air passage portion 16 is inclined from the back surface side to the front surface side in the main body case 3, first, the air direction changes from the back surface side to the front surface side in the main body case 3, and further, the first air direction adjusting means. And the wind direction changes from the back side to the front side in the main body case 3 by the second wind direction adjusting means. Thus, since the wind direction can be changed at the two locations of the casing air passage section 16 and the first wind direction adjusting means and the second wind direction adjusting means, the angle at the time of the wind direction change becomes gentle and occurs when the wind direction changes. It is possible to suppress blowing resistance.

  The air volume adjusting means is specifically a recessed portion 27 located on the front surface side of the main body case 3 of the discharge port 14 and recessed toward the front surface side of the main body case 3. Here, the discharge port 14 has a horizontally long rectangular tube shape, and has a shape in which the air passage area increases in the left-right direction in the main body case 3 from below to above. The discharge port 14 is provided with a recessed portion 27 that is recessed toward the front surface side of the main body case 3 on the side periphery of the front surface side of the main body case 3. The recess 27 is such that the upper part of the front side of the discharge port 14 on the front side of the main body case 3 is recessed a predetermined distance toward the front side of the main body case.

  When the fan unit 12 is rotated by the motor unit 11, the air outside the main body case 3 is sucked into the main body case 3 from the intake port 1 of the main body case 3, and the suction port 13 of the blowing unit 5 is passed through the air cleaning unit 4. The air is blown into the casing portion 10. The air in the casing part 10 is blown upward by the fan part 12 and flows to the discharge port 14 of the blowing means 5. The air that has flowed to the discharge port 14 flows while spreading in the left-right direction in the main body case 3, and also flows while spreading to the recess 27.

  That is, the casing air passage portion 16 connected to the first air direction adjusting means 8 is expanded, and the wind speed is reduced. As a result, it is possible to suppress the attraction of the airflow flowing into the intake port 1 of the main body by the airflow blown from the first air direction adjusting means 8.

  A wind direction adjusting unit 28 is provided between the air blowing port 2 and the front surface of the main body case 3, that is, between the air blowing port 2 and the operation unit 7. The wind direction adjusting unit 28 is an inclined surface in which the front surface side of the main body case 3 is inclined at a third angle from the horizontal plane to the elevation angle direction. This third angle is greater than 0 ° and smaller than the first angle.

  Thereby, since the wind direction adjusting unit 28 is inclined at the third angle from the horizontal plane in the elevation angle direction, when the wind from the first wind direction adjusting means 8 blows out, the wind direction adjusting unit 28 makes the angle more than the third angle. In order to blow out, attraction of the airflow flowing into the intake port 1 due to the blown airflow can be suppressed as compared with the case where the third angle is 0 °.

  As for the opening edge part 29 of the ventilation opening 2, the front side in the main body case 3 inclines the 3rd angle from the horizontal surface to the elevation angle direction. That is, the opening edge part 29 and the airflow direction adjustment part 28 of the air blowing port 2 are located on the same surface in which the front surface side in the main body case is inclined by a third angle from the horizontal plane in the elevation angle direction.

  That is, when the wind from the first wind direction adjusting means 8 spreads in the left-right direction in the main body case 3 and blows out, the opening edge 29 has a third angle from the horizontal plane to the elevation angle direction on the front side of the main body case 3. Therefore, when the wind from the first wind direction adjusting means 8 blows out, the wind direction adjusting unit 28 blows out at a third angle or more, compared with the case where the third angle is 0 °, The attraction of the airflow flowing into the intake port 1 due to the blowout airflow can be suppressed.

The air direction is changed so that air is blown from the horizontal surface to the front surface side in the main body case at a second angle from the horizontal plane to the elevation angle direction, and the first angle is the same angle as the second angle. In addition, an air volume adjusting means is provided on the upstream side of the first air direction adjusting means, and the air volume sent from the first air direction adjusting means by the air volume adjusting means is from the second air direction adjusting means. The configuration is such that the amount of air blown is smaller.
