That is, the first flow path 70 may be formed. The first flow path 70 may be formed along the upper surface of the first air flow guide 30 . The first flow path 70 may be formed so that air flow is discharged in a horizontal direction. The first air flow guide 30 may guide the air flow discharged from the air outlet 13 in a horizontal direction.

Specifically, the second protrusion 34 forms a gentle curved surface at one end of the guide plate 31 meeting the opening 32, so that the flow of air passing through the first flow path 70 can be smoothly guided. there is. In addition, noise generated when the air flow is discharged through the first flow path 70 can be reduced.

The ribs 22 of the rod support 20 may guide the air flow inside the main body 10 . Specifically, the rib 22 may guide a flow of air that is introduced into the air duct connection pipe 11 and discharged through the air outlet 13 . The rib 22 can concentrate the area of the air flow toward the air outlet 13 and increase the flow rate of the air. A plurality of ribs 22 may be provided.

It is possible to maintain a state spaced apart from the flange 12 by the length of the vertical direction of (43). (For convenience, this is referred to as an 'open state of the first flow path 70'.)

In the upward airflow discharge mode, the second flow passage 80 is in a closed state. (Description duplicated with FIG. 2 is omitted.)

That is, since the first flow path 70 is open and the second flow path 80 is closed in the upward airflow discharge mode, all airflow discharged through the air outlet 13 can move to the first flow path 70 air. The airflow discharged through the outlet 13 may be discharged in the horizontal direction of the ceiling through the first flow path 70 .

Indoor air contains pollutants such as fine dust or moisture. It is common that pollutants or moisture are mainly concentrated in the upper part of the room. The air introduced from the air duct can be discharged in the horizontal direction of the ceiling by driving the diffuser 1 in an upward airflow discharge mode. By discharging outside air in the horizontal direction of the ceiling, it is possible to prevent diffusion of contaminants or moisture concentrated in the upper part of the room. In addition, when cooling air is supplied in summer, the cooling air can be easily diffused indoors by discharging the cooling air in a horizontal direction through the first flow path 70 .

4 is a cross-sectional view showing a simultaneous airflow discharge mode of the diffuser 1 .

In the simultaneous airflow discharge mode, the first flow path 70 is open. (Description overlapped with FIG. 3 is omitted.)

The second air flow guide 50 may move downward from the first air flow guide 30 and the main body 10 . The second air flow guide 50 may be detachably coupled to the first air flow guide 30 . That is, the second air flow guide 50 can move up and down together with the up and down movement of the first air flow guide 30 in a state of being coupled with the first air flow guide 30, and is separated from the first air flow guide 30. In this state, it can move up and down from the first air flow guide 30 separately. The second air flow guide 50 may rotate and descend from the first air flow guide 30 .

When the second air flow guide 50 descends from the first air flow guide 30 , the opening 32 of the first air flow guide 30 may be opened. When the downward slope 52 of the second air flow guide 50 in contact with the opening 32 of the first air flow guide 30 moves downward, the opening 32 may be opened. A space through which air can be discharged may be formed between the lower part of the first air flow guide 30 and the upper part of the downward inclined surface 52 by the downward slope of the downward slope 52 . That is, the second flow path 80 may be formed. The second passage 80 may be formed along the downward slope 52 . The second passage 80 may be formed to discharge air flow downward. The downward slope 52 may guide the second flow path 80 downward of the ceiling.

The second air flow guide 50 may guide the air flow discharged from the opening 32 of the first air flow guide 30 downward. That is, the air flow discharged from the air outlet 13 may move to the opening 32 of the first air flow guide 30 and be discharged downward through the second flow path 80 .

The first protrusion 33 of the first air flow guide 30 may guide the air flow through the second flow path 80 . Specifically, the first protrusion 33 allows one end of the guide plate 31 meeting the opening 32 to be formed in a gently curved surface, so that the flow of air passing through the second flow path 80 can be smoothly guided. there is. The first protrusion 33 can adjust the downward angle at which the airflow discharged from the opening 32 moves. In addition, since the first protrusion 33 protrudes downward from the lower surface of the guide plate 31, the air moved to the opening 32 of the first air flow guide 30 can be guided to flow downward. As the downward slope 52 moves downward, the discharge angle of the airflow becomes closer to the vertical direction toward the downward direction. That is, the discharge angle of the airflow passing through the second flow passage 80 is changed according to the distance the second airflow guide 50 is separated from the first airflow guide 30, and the first protrusion 33 is the second airflow guide. It is possible to reduce the amount of change in the discharge angle of the air flow according to the separation distance of (50). That is, the first protrusion 33 serves as a damper to prevent the airflow discharge angle from rapidly changing according to the separation distance of the second airflow guide 50 .

The shortest distance from the lower end of the first protrusion 33 to the downwardly sloped surface 52 may be less than twice the shortest distance from the inner circumferential surface of the opening 32 to the outer surface of the rod 51 .

The bridge 53 may guide the movement of the air flow discharged from the air outlet 13 in the vertical direction. Bridge 53 may prevent recirculation of airflow through aperture 32 . The bridge 53 may concentrate the airflow passing through the opening 32 and increase the flow rate. The bridge 53 may be formed in a wedge shape. A plurality of bridges 53 may be provided, and a total cross-sectional area of the plurality of bridges 53 in a vertical direction may be less than 1/3 of the area of the opening.

The bridge 53 is in contact with the opening 32 so that the second air flow guide 50 may be supported by the first air flow guide 30 . The outer surface 54 of the bridge 53 is supported on the inner circumferential surface of the opening 32, so that the second air flow guide 50 is lowered from the main body 10 and the first air flow guide 30 and can be fixed. That is, the outer surface 54 of the bridge 53 may be provided to correspond to the shape of the inner circumferential surface of the opening 32 of the first air flow guide 30 .

The second air flow guide 50 is fixed in a lowered state from the main body 10 and the first air flow guide 30 by being supported by the hooking jaw 55 formed on the upper part of the rod 51 being caught by the rod support 20. It can be. (For convenience, this is referred to as 'an open state of the second flow path 80'.)

That is, since both the first flow path 70 and the second flow path 80 are open in the simultaneous air flow discharge mode, a part of the air flow discharged through the air outlet 13 moves to the first flow path 70 and the rest is removed. 2 Move to Euro (80). The air that has moved to the first flow path 70 is discharged in a horizontal direction, and the air that has moved to the second flow path 80 is discharged downward. At this time, the ratio of the airflow moving to the first flow path 70 or the second flow path 80 may be adjusted according to the number or shape of the bridges.

By driving the diffuser 1 in the simultaneous airflow discharge mode, the air introduced from the air duct can be discharged not only in the horizontal direction of the ceiling but also downward. By simultaneously discharging outside air horizontally and downward from the ceiling, it is possible to prevent diffusion by covering contaminants and moisture concentrated in the upper part of the room as well as contaminants and moisture that have settled down in the lower part of the room. For example, when the diffuser 1 is installed and operated in conjunction with a kitchen hood, it is possible to prevent contaminants in the air inside the kitchen from spreading to spaces other than the kitchen.

5 is a cross-sectional view showing the downward air flow discharge mode of the diffuser 1.

In the downward airflow discharge mode, the first flow passage 70 is in a closed state. (Description duplicated with FIG. 2 is omitted.)
