The present disclosure relates to an air purifier, and more specifically, to an air purifier for improving an air flow in an interior space by guiding a discharge direction of flowing air.
It should be noted that the contents described in this section merely provide background information for the present invention and do not constitute prior art.
Generally, an air purifier intakes contaminated indoor air and filters out dust and odor particles contained in the air using a filter, thereby purifying the air having been intaken to make clean air. The air, purified as described above, is then discharged externally from the air purifier, that is, indoors.
In other words, after the air purifier intakes and purifies contaminated ambient air, the air purifier purifies air around a position in which the air purifier is installed while discharging clean air externally.
To this end, generally, the air purifier may include a blower allowing ambient air to flow in to be discharged as purified air, and filters for filtering dust contained in the air flowing in, odor particles, and the like.
However, the air purifier according to the related art has a structure having an air inlet in one side of a housing, and an air outlet in the other side, a side surface, or an upper surface.
In the air purifier having the structure described above, an air flow in an indoor space is only actively generated in a direction of the air inlet, and in a space in a direction of the air outlet. In the remainder of the indoor space, an air flow is relatively weak. Thus, there may be a disadvantage, in that it may be difficult to purify the entirety of the air within an indoor space in a short amount of time through all of the air of the indoor space flowing through the air purifier.
Moreover, a direction of discharging air from the air purifier may be limited, such that there may be a problem in which circulation of the entirety of air in an interior space in which the air purifier is provided is difficult to achieve.
Thus, the air purifier according to the related art has a disadvantage in which the purifying efficiency of air is low, as compared to an air volume.
The present disclosure is realized by recognizing at least one of a request or a problem generated in an air purifier according to the related art.

The air purifier 10 may have the air purifying mode M1 of discharging air purified in the purifier main body 100 as the first air blowing means 200 is driven and the second air blowing means 400 is stopped, the blowing mode M2 of blowing air introduced as the first air blowing means 200 is stopped and the second air blowing means 400 is driven, and the purifying and blowing mode M3 of blowing air by applying additional discharge force to purified air, discharged by the first air blowing means 200, with the second air blowing means 400 toward an interior space as the first air blowing means 200 and the second air blowing means 400 are driven together.
As illustrated in
In the case of the air purifying mode M1, a foreign object, such as a dust particle floating in an interior space, or the like, is removed, so purified air is discharged indoors. Thus, an effect of improving a quality of indoor air may occur.
In addition, in the case of the air purifying mode M1, although purified air is not strongly discharged, an advantage in which noise generated by the air purifier 10 is reduced may occur.
As illustrated in
In the case of the blowing mode M2, air introduced into the air purifier 10 is strongly discharged. Thus, an effect in which air circulation throughout a room is formed may occur.
As illustrated in
In the case of the purifying and blowing mode M3, purified air is discharged indoors, so a quality of indoor air may be improved. In addition, air introduced to the air purifier 10 is strongly discharged. Thus, an advantage in which air circulation, throughout a room, is formed may occur.
However, as the first air blowing means 200 and the second air blowing means 400 are driven at the same time, compared to the air purifying mode M1, noise generated by the air purifier 10 may increase.
