Japanese Patent No. 4840181

  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.

  However, if the blowing angle is reduced, the blowing airflow from the air blowing port and the suction airflow flowing into the main body inlet on the floor approach each other, and the blowing airflow attracts a part of the dirty air toward the suction port of the air purifier. Therefore, there are cases where the room is recirculated before being sucked into the main body of the air purifier.

  Therefore, the present invention solves the above-described conventional problems, and provides an air cleaning device that increases the wind speed of the airflow flowing into the intake port on the floor and suppresses the attraction of the sucked airflow by the blown airflow. Objective.

In order to achieve this object, the present invention provides a main body case having an air opening that opens upward, an air cleaning means provided in the main body case, and a first air direction adjusting means provided in the air outlet. And a second wind direction adjusting means, wherein the first wind direction adjusting means is located on the front side of the main body case and blows air from the horizontal surface to the front side of the main body case at a first angle in the elevation direction. The second wind direction adjusting means is positioned on the back surface side of the main body case, and the second wind direction adjusting means changes the wind direction so as to blow the air from the horizontal surface to the front surface side of the main body case at a second angle in the elevation direction. The first angle is greater than 0 ° and less than 45 °, the second angle is greater than 0 ° and less than 90 °, and the second angle is greater than the second angle. 1 angle Ri rather large, between the front of the blower port and the main body case is provided with a wind direction adjustment unit, the airflow-direction adjustment unit, the front side of the main body case, to tilt the third angle from the horizontal plane to the direction of elevation angle The third angle is characterized in that it is larger than 0 ° and smaller than the first angle , thereby achieving the intended purpose.

According to the present invention, a main body case having an air outlet opening upward, an air cleaning means provided in the main body case, a first air direction adjusting means and a second air direction adjusting means provided in the air outlet, The first wind direction adjusting means is located on the front surface side of the main body case, and changes the wind direction so that air is blown from the horizontal plane to the front surface side of the main body case at a first angle from the horizontal plane, The second wind direction adjusting means is located on the back side of the main body case and changes the wind direction so as to blow from the horizontal plane to the front side of the main body case at a second angle from the horizontal plane to the first angle. Is within a range greater than 0 ° and less than 45 °,
Angle is greater than 0 °, smaller than 90 ° range, the second angle, the first angle from the rather large, between the front of the blower port and the main body case, the airflow-direction adjustment unit The wind direction adjusting unit is configured such that the front side of the main body case is inclined at a third angle from the horizontal plane to the elevation angle direction, and the third angle is larger than 0 ° and smaller than the first angle. It is a thing.

  Thereby, although the second wind direction adjusting means is blowing air upward from the first wind direction adjusting means, the wind that is changed by the first wind direction adjusting means is emitted from the horizontal plane in the elevation direction. Since air is blown in a range larger than 0 ° and smaller than 45 °, the vortex of the airflow circulating through the entire room is lower than the vortex in the case where the airflow is larger than 45 ° from the horizontal plane to the elevation direction, and on the floor. The vertical height of the airflow flowing into the air inlet of the main body becomes small. Thereby, the wind speed of the airflow flowing into the intake port on the floor can be increased.

  Here, since the second angle is larger than 0 ° and smaller than 90 °, the entire room is circulated, and the second angle is larger than the first angle. By blowing upward from the first wind direction adjusting means, the wind blown out from the air blowing port 2 is dispersed, and the wind speed of the wind coming out from the first wind direction adjusting means is suppressed. It is possible to prevent the sucked air from being attracted by the blowing airflow and recirculated.

  As a result, it is possible to increase the wind speed of the airflow flowing into the intake port on the floor and to suppress the attraction of the airflow flowing into the intake port due to the blowing airflow.

  The air purifier according to claim 1 of the present invention includes a main body case having a blower opening that opens upward, an air purifying means provided in the main body case, and a first air direction adjusting means provided in the blower opening. Second wind direction adjusting means, wherein the first wind direction adjusting means is formed of a first wind direction plate and a first shaft portion that pivotally supports the first wind direction plate on the air blowing port, The first wind direction plate is located on a front surface side of the main body case, and the front surface side of the main body case opens a first angle from a horizontal plane to an elevation angle direction. The second wind direction plate is formed on the rear side of the main body case, and the second wind direction plate is formed on the rear side of the main body case. The front side of the case opens a second angle from the horizontal plane in the elevation direction. The first angle is greater than 0 ° and less than 45 °, the second angle is greater than 0 ° and less than 90 °, and the second angle is greater than the first angle. It has a configuration characterized by being larger than the angle.

  Thereby, although the second wind direction adjusting means is blowing air upward from the first wind direction adjusting means, the wind that is changed by the first wind direction adjusting means is emitted from the horizontal plane in the elevation direction. Since the air is blown in a range larger than 0 ° and smaller than 45 °, the vortex of the airflow circulating through the entire room is lower than the vortex in the case where the airflow is larger than 45 ° in the elevation direction from the horizontal plane. The wind direction adjusting means distributes the blown-out wind by blowing air upward from the first wind direction adjusting means, and suppresses the wind speed of the wind coming out of the first wind direction adjusting means. The vortex circulating through the room is lowered downward by the wind from the wind direction adjusting means, so that the suction speed of the air purifier in the space of 30 cm above the floor is increased, and the blown-out air is first blown by the second wind direction adjusting means. Wind direction adjustment hand Than wind exiting By spreading upward, it is air cleaning while preventing recirculating to attract the blowing airflow of air sucked in the vicinity of the air cleaning apparatus, an effect that.

  In addition, a wind direction adjustment unit is provided between the air outlet and the front surface of the main body case, and the front side of the main body case is inclined at a third angle from the horizontal plane to the elevation direction. The third angle may be larger than 0 ° and smaller than the first angle. Thereby, when the wind which comes out of a 1st wind direction adjustment means blows off by a wind direction adjustment part making a 3rd angle, since a 3rd angle blows out more than a 3rd angle by a wind direction adjustment part, a 3rd angle is 0. Compared with the case where the angle is °, it is less affected by the suction airflow, and it is more difficult to recirculate the sucked air.

  Moreover, the opening edge part of the said air blower is the structure that the front side in the said main body case inclines a 4th angle from a horizontal surface to an elevation angle direction, and this 4th angle is the same as the said 3rd angle. It may be. Thereby, since the angle between the surface with the suction port and the surface with the air blowing port becomes larger than 90 ° because the wind direction adjusting portion forms the third angle, the wind from the first wind direction adjusting means blows out. When the third air angle is blown out by the wind direction adjusting unit at the third angle or more, it is less affected by the suction airflow than when the third angle is 0 °, and the sucked air is more difficult to recirculate. There is an effect.

  The first shaft portion has a predetermined distance upward, and walls that connect the body case and the left and right edges of the first wind direction plate are provided on the left and right sides of the first wind direction plate, and the first wind direction adjusting means May be formed in a U-shape such as a tunnel, and the second wind direction plate may be covered with a distance above the first wind direction plate. As a result, among the winds from the second wind direction plate, the resistance of the wind that blows forward increases, so that part of the wind that exits from the second wind direction plate leaks to the left and right, and the stagnation of the air purifier on the left and right This prevents the dust from accumulating on the left and right sides of the air purifier.

  Further, the first wind direction plate may be configured to be longer in the left-right direction in the main body case than the second wind direction plate. As a result, the wind leaks to the left and right behind the air purifier, so the stagnation on the left and right is prevented by leaking the wind to the left and right behind the air purifier, and dust accumulates on the left and right of the air purifier. The effect is to prevent.

As shown in FIG. 1 and FIG. 2, the air purifier of the present embodiment includes a main body case 3 having an air inlet 1 and an air outlet 2, an air purifying means 4 provided in the main body case 3, and an air blowing means. 5, a control means 6, and an operation unit 7.

  The main body case 3 has a vertically long rectangular box shape, and is provided with an air inlet 1 at a lower portion of the front surface of the main body case 3, and a horizontally elongated air blowing port 2 is provided on the back side of the top surface of the main body case 3. The blower opening 2 is provided with first wind direction adjusting means 8 and second wind direction adjusting means 9 which are provided so as to be freely opened and closed.

  The air cleaning means 4 is provided in the vicinity of the air inlet 1 of the main body case 3, and is an air cleaning filter as an example. A pleat-shaped filter medium part (not shown) and a rectangular tube-shaped frame part (not shown) for fixing the filter medium part are formed. When air passes through the filter medium, dust in the air is collected.

  The air blowing means 5 is located in the air path between the air cleaning means 4 and the air blowing port 2 of the main body case 3, and is formed of a casing part 10, a motor part 11, and a fan part 12.

Here, the first angle is greater than 0 ° and less than 45 °, the second angle is greater than 0 ° and less than 90 °, and the second angle is greater than the first angle. It is a big point.

  As a result, the second wind direction adjusting means 9 is blown upward from the first wind direction adjusting means 8, but the wind that has been changed by the first wind direction adjusting means 8 is emitted from the horizontal plane. Since the air is blown in a range larger than 0 ° and smaller than 45 ° in the elevation direction, the vortex of the airflow circulating through the entire room is lower than the vortex in the case where the airflow is larger than 45 ° from the horizontal plane in the elevation direction. The vertical height of the airflow flowing into the air inlet 1 of the main body case 3 on the floor is reduced.

  Here, the second wind direction adjusting means 9 disperses the air blown from the air blowing port 2 by being blown upward from the first air direction adjusting means 8, thereby reducing the amount of air blown from the air blowing port 2. Since the wind speed of the wind which comes out of the 1st wind direction adjustment means 8 is suppressed without reducing, it can suppress that the air suck | inhaled in the air-cleaning apparatus vicinity is attracted by a blowing airflow, and is recirculated.

  As a result, it is possible to increase the wind speed of the airflow flowing into the intake port 1 on the floor and to suppress the attraction of the airflow flowing into the intake port due to the blowing airflow.

  Further, since the wind that has been changed in direction by the first wind direction adjusting means 8 is blown in the range of greater than 0 ° and less than 45 ° in the elevation direction from the horizontal plane, even when it hits the ceiling, the ceiling surface Since the air is blown in the depression direction in a range smaller than 45 °, the air can smoothly travel along the ceiling, change the wind direction downward along the wall, and easily generate an air current circulating through the entire room.

  In addition, the air inlet 1 is provided in the lower part of the front surface of the main body case 3, and the air outlet 2 is provided on the back side of the top surface of the main body case 3. That is, since the air inlet 1 and the air outlet 2 are located on different surfaces of the main body case 3, it is possible to suppress the attraction of the suction airflow due to the blown airflow.

  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 the present embodiment, a wind direction adjusting unit 27 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 27 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 adjustment part 27 inclines by the 3rd angle from the horizontal surface to an elevation angle direction, when the wind from the 1st wind direction adjustment means 8 blows off, it is more than 3rd angle by the wind direction adjustment part 27. Therefore, in comparison with the case where the third angle is 0 °, the attraction of the airflow flowing into the intake port due to the blown airflow can be suppressed.

  In addition, the opening edge portion 28 of the blower opening 2 is inclined at a third angle in the elevation direction from the horizontal plane on the front side of the main body case 3. In other words, the opening edge portion 28 and the airflow direction adjusting portion 27 of the air blowing port 2 are located on the same surface where the front surface side of the main body case is inclined at the 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 portion 28 has a third angle from the horizontal plane to the elevation angle direction. Therefore, when the wind from the first wind direction adjusting means 8 blows out, the wind direction adjusting unit 27 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 due to the blowout airflow can be suppressed.
