The present invention provides an air purifier that includes: a purifier body; a first air blower which is provided in the purifier body to introduce, purify and discharge outside air; an air guidance part which is provided on the movement path of the air discharged from the first air blower and is pivotably coupled to the upper end of the purifier body to guide an air discharge direction; and a second air blower which is installed on the air guidance part to blow air.

TECHNICAL FIELD

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.

BACKGROUND ART

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 semi-curved protruding member316of the positioning rod315is pressed by the elastic member317, so the semi-curved protruding member is prevented from being easily separated from the positioning groove341into which the semi-curved protruding member is inserted.

The purifier main body100may have the main housing110, and a guide top130.

As illustrated inFIG. 3, the purifier main body100may have the main housing110having an internal space, in which the first air blowing means200is installed, and the guide top130provided in an upper surface of the main housing110and having the air guidance part300mounted thereon.

As illustrated inFIG. 6, at least one air inlet131, through which external air flows, may be formed in the guide top130.

Outdoor air may be introduced through the air inlet131formed in the guide top130by discharge force introduced by the second air blowing means400.

Although not illustrated, the cover top310is installed in the guide top130to be rotated so as to allow the air guidance part300and the second air blowing means400installed in the air guidance part300to be rotated above the purifier main body100.

The cover top310is installed in the guide top130to be rotated, so as to allow the air guidance part300and the second air blowing means400installed in the air guidance part300to be rotated above the purifier main body100. A first rail portion is provided in an upper surface of the guide top130, and a second rail portion installed in the first rail portion to be rotated is provided in the cover top310.

In this case, in order to easily rotate the cover top310in the guide top130, the first rail portion and the second rail portion are provided as members having the form of a ring to correspond to each other.

The first air blowing means200and the second air blowing means400may be provided to be driven independently of each other.

As illustrated inFIGS. 7A through 7C, the air purifier10may have an air purifying mode M1, a blowing mode M2, and a purifying and blowing mode M3.

As illustrated inFIG. 7A, in the air purifying mode M1, only the first air blowing means200is driven, so air moves through a first inflow path S1.

As illustrated inFIG. 7B, in the blowing mode M2, only the second air blowing means400is driven, so air moves through a second inflow path S2.

As illustrated inFIG. 7C, in the purifying and blowing mode M3, the first air blowing means200and the second air blowing means400are driven together, so air moves through the first inflow path S1and the second inflow path S2.

The air purifier10may have the air purifying mode M1of discharging air purified in the purifier main body100as the first air blowing means200is driven and the second air blowing means400is stopped, the blowing mode M2of blowing air introduced as the first air blowing means200is stopped and the second air blowing means400is driven, and the purifying and blowing mode M3of blowing air by applying additional discharge force to purified air, discharged by the first air blowing means200, with the second air blowing means400toward an interior space as the first air blowing means200and the second air blowing means400are driven together.

As illustrated inFIG. 7A, when the air purifying mode M1is executed, the first air blowing means200is driven, and the second air blowing means400is stopped. In other words, air purified in the purifier main body100may be discharged indoors by the first air blowing means200.

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 purifier10is reduced may occur.

As illustrated inFIG. 7B, when the blowing mode M2is executed, the first air blowing means200is stopped, and the second air blowing means400is driven.

In the case of the blowing mode M2, air introduced into the air purifier10is strongly discharged. Thus, an effect in which air circulation throughout a room is formed may occur.

As illustrated inFIG. 7C, when the purifying and blowing mode M3is executed, the first air blowing means200, and the second air blowing means400may be driven together.

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 purifier10is strongly discharged. Thus, an advantage in which air circulation, throughout a room, is formed may occur.

However, as the first air blowing means200and the second air blowing means400are driven at the same time, compared to the air purifying mode M1, noise generated by the air purifier10may increase.

While the present disclosure has been particularly shown and described with reference to exemplary embodiments thereof, but is not limited thereto. It is apparent to those skilled in the art that various changes and modifications thereof may be made within the spirit and scope of the present disclosure, and therefore to be understood that such changes and modifications belong to the scope of the appended claims.
