Description

  The present invention relates to an air cleaning device for cleaning indoor air.

  The air in the living room is polluted with various substances such as dust, cigarette smoke, and carbon dioxide discharged with the breathing of the occupants. Substances are likely to stay indoors, so active ventilation is necessary. However, in rooms with severe air pollution and in rooms where hay fever residents live and work, it is often not possible to leave the windows open to ventilate, and air purification devices are used.

The air cleaning device includes a blower housed in a housing having a suction port on a rear surface and having a blower outlet on an upper portion thereof, and a filter through which air sucked from the suction port is passed by the blower. The clean air to be blown out is blown upward, backward or in an oblique direction inclined about 50 ° with respect to the vertical direction (see, for example, Patent Document 1).

  FIG. 8 is an explanatory view showing the flow direction of the clean air blown out from the air outlet of the air purifier installed on the floor in the room. By the way, as shown in FIG. 8, an air purifier configured to blow clean air from the upper blowout outlet upward, backward, or in an oblique direction inclined about 50 ° with respect to the vertical direction as shown in FIG. It is used by being installed near the wall in the room. However, in this air purifier, when the clean air is blown upward from the blower outlet, the blown clean air hits the ceiling in the room and flows forward and backward with respect to the air purifier as shown in FIG. Since the direction is bisected, the clean air cannot be circulated throughout the room, and when the clean air is blown backward from the blowout port, the clean air hardly flows forward in the room, and the clean air cannot be circulated in the room. Because when the clean air is blown from the outlet in an oblique direction inclined about 50 ° with respect to the vertical direction, the rising speed after hitting the wall becomes relatively slow. The amount of clean air flowing forward along the ceiling with respect to the air purifier is small, and an improvement measure has been desired.

  In addition, since the centrifugal air blower including a casing having a sirocco fan and a blower opening opened in the centrifugal direction of the sirocco fan is used for the air purifier, the centrifugal blower blows clean air from the blower outlet of the housing into the room. When blowing out, the wind speed at one side of the outlet becomes faster than the wind speed at the other side, the amount of clean air blown out will be biased, and the direction of blowout at the outlet will be deflected. But an improvement plan was requested.

  The present invention has been made in view of such circumstances, and a main object of the present invention is to incline indoors by inclining the direction of clean air blown from the blowout port of the housing into the room by 15 to 20 ° with respect to the vertical direction.

In the air purifier that blows clean air to be blown from the blowout port, the blowout direction of the clean air blown from the blowout port is inclined by 15 to 20 ° with respect to the vertical direction.

In the present invention, when the air outlet is installed near the wall so that the inclined side of the air outlet becomes the wall of the room, the clean air blown from the air outlet is inclined at an angle of 15 to 20 ° with respect to the wall. It can be applied to the wall and raised along the wall, and the flow direction of clean air can be concentrated. Therefore, the clean air blown out from the air outlet can flow forward with respect to the air purifier along the ceiling in the room, and the clean air can be circulated throughout the room.
In addition, when the inclination angle in the blowing direction is less than 15 °, the clean air blown out from the blowout outlet hits the wall near the ceiling, and the amount of clean air flowing forward to the air purifier along the ceiling is reduced. However, it is difficult to circulate throughout the room. In addition, when the inclination angle in the blowing direction exceeds 20 °, the ascending speed after hitting the wall becomes relatively slow, the amount of clean air flowing forward with respect to the air purifier along the ceiling is reduced, and the clean air is reduced. It is difficult to circulate throughout the room.

Moreover, it is preferable that the air purifier which concerns on this invention is set as the structure provided with the air guide path which guides the clean air which the said air blower blows to the said blower outlet along the said blowing direction.
In the present invention, since the clean air can be guided in the blowing direction before reaching the blowout port, the wind speed of the clean air blown from the blowout port can be increased, and the floor is relatively Even in a room with a large area, it is easy to circulate clean air throughout the room.

Moreover, it is preferable that the air purifying apparatus according to the present invention has a configuration in which a speed distribution leveling body that equalizes a speed distribution in the entire area of the blowout port of the clean air blown by the blower is provided in the blowout port.
In this invention, since the velocity distribution in the entire area of the blowout port of the clean air can be leveled, it is possible to suppress the clean air from being biased to one side of the blowout port, and the clean air that has been blown out The amount of variation can be reduced.

  According to the present invention, the clean air blown from the outlet can be applied to the wall at an inclination angle of 15 to 20 ° with respect to the wall and can be raised along the wall. The clean air that has been blown out can be caused to flow forward with respect to the air purifier along the ceiling of the room, and the clean air can be circulated throughout the room.
