Generally, an air purifier is a sanitary device that sucks contaminated indoor air and purifies fine particles such as dust and odor particles contained in the air through a filter, clean it with clean air, and discharges it again to the outside, that is, an indoor space.

That is, the air cleaner sucks and cleans the contaminated ambient air in the indoor space, and then purifies the air in the indoor space while discharging clean air into the indoor space.

Accordingly, the air cleaner is manufactured in a form having various capacities, and the consumer purchases an air cleaner having an appropriate capacity according to the size of the indoor space to use the air cleaner. Generally, the larger the capacity of the air cleaner, the more air can be cleaned in the indoor space, and the larger the capacity of the air cleaner in the indoor space of the same size, the more clean the air to the space.

Generally, the air cleaner is equipped with a blowing fan inside the case body so as to be able to suck and discharge outside air, and a filter for filtering the sucked air is provided. A suction port for sucking air is formed at one side of the case and a discharge port for discharging purified air is formed at the other side of the case and the discharge port is formed in a separate grill shape.

Such an air purifier performs the function of sucking and discharging air through a blowing fan, continuously sucking and purifying indoor air, and discharging the indoor air to perform an air purifying function for the indoor space. Therefore, it is possible to improve the air cleaning performance, for example, the time required to purify the specific indoor space to the reference state, according to the suction and discharge function of the air through the air blowing fan.

A general air purifier according to the related art is mainly focused on improving the air purifying performance by simply increasing the capacity of the air blowing fan to increase the suction and discharge amount of the air. This increases the size of the air purifier, There is a problem that the space occupying the space increases. On the other hand, when the capacity of the air blowing fan is reduced to reduce the size and cost of the air cleaner, the air cleaning performance is deteriorated.

The air purifier includes a main case 100, an air filter 200, a blowing fan 300, A module 400, a rotating grill 500, and a grill rotation driving module 600.

The main casing 100 is configured to form an outer shape of the air purifier. The main casing 100 has a suction port 110 for sucking outside air on one side of the outer circumference, and a discharge port 140 for discharging purified air to the outside .

In addition, a handle may be formed on the upper end of the main case 100 to carry the air purifier.

The air filter 200 is installed in the inner space of the main case 100 to filter external air sucked through the suction port 110. The air filter 200 is formed into a hollow cylindrical shape corresponding to the shape of the suction port 110 of the main case 100 . Therefore, the air flowing into the internal space through the inlet 110 passes through the hollow cylindrical air filter 200 in all directions and flows into the internal space of the air filter 200.

The air blowing fan 300 blows air such that the outside air passes through the air inlet 110 and the air filter 200 and is discharged to the air outlet 140. The air blower 300 is installed in the inner space of the main case 100, On the upper portion of the intermediate frame 104. [ The air filter 200 is located at a lower portion of the intermediate frame 104 and the blowing fan 300 is positioned in the vertical upper portion of the hollow region of the air filter 200. At this time, the blowing fan 300 is applied as a centrifugal blowing fan that sucks air from the lower axial direction to blow air in the radial direction. The air introduced through the inlet 110 flows into the hollow region of the air filter 200 through the air filter 200 by the air blowing fan 300 and flows into the hollow region of the air filter 200 from the hollow region of the air filter 200, (300) and flows in the radial direction of the blowing fan (300).

The duct module 400 is installed inside the main case 100 and guides the air flow path so that the flow of the air blown by the blowing fan 300 is directed toward the discharge port 140. That is, the duct module 400 is formed to guide the air blown in the radial direction from the blowing fan 300 to the discharge port 140 side. 3, the duct module 400 includes a core duct 410 disposed at an upper portion of the blowing fan 300 and a plurality of ducts 410 extending from the discharge duct 140 in a manner to surround the outer space of the core duct 410 in a spaced- And the outer duct 420 is formed in the shape of a hollow pipe whose upper surface and lower surface are both opened. . According to the structure of the duct module 400, a flow of air radially blown from the blowing fan 300 is guided to the discharge port 140 along the space between the core duct 410 and the external duct 420.

The rotary grill 500 is formed in a disc shape, and a plurality of ribs 510 are formed to be spaced apart from each other, and air is discharged through the spacing space between the plurality of ribs 510.

The air purified by the air filter 200 flows in the radial direction of the blowing fan 300 from the hollow region of the air filter 200 through the blowing fan 300. The air flowing in the radial direction of the blowing fan 300 is discharged to the discharge port 140 along the space between the core duct 410 and the external duct 420.

Accordingly, air can be smoothly discharged through the air blowing fan 300 and the duct module 400 to the discharge port 140 without air leakage or air flow in the air flowing in the main casing 100, Since the air is sucked along the entire circumference of the main case 100, the air intake amount can be improved and the discharge port 140 is formed in a donut shape corresponding to the shape of the duct module 400, . Accordingly, the suction amount and the discharge amount of the air can be increased without increasing the capacity of the air blowing fan 300, so that the air cleaning performance can be improved.

In addition, by configuring the rotary grill 500 to be rotatable through the rotary drive module 600 on the discharge port 140, the flow of the air discharged through the discharge port 140 can be changed into a rotating form, Accordingly, the air flow in the indoor space in which the air cleaner is disposed is also actively actuated, so that the flow and diffusion of the air to the entire indoor space can be performed more quickly and smoothly, thereby improving the air cleaning performance for the indoor space .

The inner frame 530 is formed concentrically with the outer frame 520. The inner space of the inner frame 530 is formed to be in contact with the inner frame 530. The outer frame 520 is formed around the outer circumference of the outer frame 520, . The plurality of ribs 510 are formed so as to be spaced apart in parallel in a direction transverse to the rotary grill 500. A separate intermediate frame 540 may be additionally formed along the circumferential direction in the space between the inner frame 530 and the outer frame 520 to reinforce the strength of the plurality of ribs 510. [

The rotary grill 500 may be rotatably coupled to the upper end of the outer duct 420 of the duct module 400 as shown in FIG. To this end, a seating groove 421 is formed in the upper end of the outer duct 420 along the inner circumference thereof, and an outer side surface of the outer frame 520 is seated in the seating groove 421 of the outer duct 420 A seating projection 521 is formed along the circumference of the circumference. The rotary grill 500 is configured to be rotatable in a state in which the seating projection 521 of the outer frame 520 is seated in the seating groove 421 of the outer duct 420.

The rotary grill 500 is attached to the discharge port 140 of the main case 100 and changes the flow of air discharged through the discharge port 140. That is, since the plurality of ribs 510 are arranged in parallel in the direction transverse to the outer frame 520, air is discharged to the outside through the spacing spaces between the ribs 510, When the rotary grill 500 rotates, the flow of the air discharged through the spaces between the ribs 510 is simultaneously rotated by the rotation of the rotary grill 500. As a result, the flow of the discharged air is rotated, Thereby diffusing the motion of the air to the space to improve the suction and discharge performance of the air and improve the air cleaning performance.

When the rotary grill 500 rotates in this state, The air is more actively rotated and the motion of the indoor air is diffused. Accordingly, the suction and discharge performance of the air can be improved and the air cleaning performance can be indirectly improved.

As shown in FIG. 6 (a), the two side surfaces contacting with the air may be inclined. In this case, the flow of the discharged air It changes along the slope and appears in an inclined upward direction.

A plurality of ribs 510 may be formed so that one of the two side surfaces contacting with air as shown in Figures 6 (b) and 6 (c) forms a vertical surface and the other side surface forms an inclined surface have. Particularly, as shown in FIG. 6 (b), a side surface of one of the two side surfaces contacting the air has a vertical surface, and a side surface of the other side surface has a narrower spacing distance from the adjacent rib 510 The flow cross-sectional area through which the air passes becomes narrower toward the upper end of the rib 510, so that the flow rate of the discharged air increases in the process of passing through the rib 510, The movement of the indoor air can be further diffused through the change of direction. In this case, since the suction and discharge performance of the air is further improved, the air cleaning performance can be further improved.
