Description

diffuser

[0001] Various embodiments of the present disclosure relate to a diffuser, and more particularly, to an air diffuser installed indoors to suck in and discharge air through a duct.

[0002] Typically, diffusers are installed on the ceiling and connected to air ducts within the ceiling, allowing them to supply outside air into the room or exhaust indoor air. The outside air discharged from the diffuser can evenly disperse pollutants floating in the room within a designated space, thereby enhancing ventilation performance. Furthermore, the outside air discharged from the diffuser can function as an air curtain, preventing pollutants from spreading to other spaces.

[0003] The damper installed in the diffuser can open and close the flow path by moving up and down to adjust its height. The path of air movement within the diffuser can be changed depending on the damper height.

[0004] Meanwhile, when outside air drawn in through an air duct passes through a diffuser and is discharged indoors, the airflow discharged from the diffuser may be discharged in a biased direction. Furthermore, if the airflow velocity of the air discharged from the diffuser is excessively fast, it may not be easy to provide ventilation. In such cases, the ventilation performance of the diffuser may be reduced, or pollutants may easily spread to other spaces. Therefore, an internal structure may be required to form a guide path for the airflow within the diffuser so that the outside air discharged from the diffuser is discharged in a uniform direction, and to appropriately control the airflow velocity of the air discharged from the diffuser.

[0005] A diffuser according to one embodiment of the present disclosure can be installed indoors to provide a diffuser that draws in air through a duct and discharges it uniformly.

[0006] A diffuser according to one embodiment of the present disclosure can diffuse and discharge air introduced into an inlet located at a discharge end of an air duct installed in a horizontal direction into a room. The diffuser may include a main body connected to the air duct and including an air outlet, a rod located inside the main body and capable of being vertically raised and lowered, a damper connected to one end of the rod and configured to open and close the air outlet, and a curved distribution plate forming a path so that the air introduced in a horizontal direction is distributed in a plurality of directions inside the main body. The distribution plate may be arranged to be spaced apart from the inlet in a horizontal direction by a predetermined distance.

[0007] A diffuser according to one embodiment of the present disclosure can diffuse and discharge air introduced into an inlet located at a discharge end of an air duct installed in a horizontal direction into a room. The diffuser may include a main body connected to the air duct and including an air discharge port, a rod located inside the main body and capable of being vertically raised and lowered, a damper connected to one end of the rod and configured to open and close the air discharge port, a handle located below the damper and configured to adjust the height of the damper, and a curved distribution plate forming a flow path so that the air introduced in a horizontal direction is distributed in a plurality of directions inside the main body. The distribution plate may be arranged to be spaced apart from the inlet in a horizontal direction by a predetermined distance. When the air discharge port is opened, a first guide flow path may be formed by rotation of the handle to discharge air in a vertical direction from the air discharge port, or a second guide flow path may be formed to discharge air in a horizontal direction from the air discharge port.

[0008] However, the problem to be solved in this disclosure is not limited to the problem mentioned above, and may be determined in various ways without departing from the spirit and scope of this disclosure.

[0021] The embodiments of this document and the terminology used herein are not intended to limit the technical features described in this document to specific embodiments, but should be understood to include various modifications, equivalents, or substitutes of the embodiments. In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more of the items, unless the context clearly indicates otherwise. In this document, phrases such as "A or B," "at least one of A and B," "at least one of A or B," "A, B, or C," "at least one of A, B, and C," and "at least one of A, B, or C" can each include any one of the items listed together in the corresponding phrase, or all possible combinations thereof. Terms such as "first," "second," or "first" or "second" may be used simply to distinguish the corresponding component from other corresponding components, and do not limit the corresponding components in any other respect (e.g., importance or order). When a component (e.g., a first component) is referred to as being "coupled" or "connected" to another component (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0022] According to one embodiment, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and placed in other components. According to one embodiment, one or more components or operations of the above-described components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., a module or a program) may be integrated into a single component. In this case, the integrated component may perform one or more functions of each component of the plurality of components in a manner identical to or similar to that performed by the corresponding component among the plurality of components prior to the integration.

[0023] A diffuser (e.g., diffuser (1) in Fig. 1) is a ventilation device for discharging air (e.g., supply air or outdoor air) drawn in from a duct (e.g., duct (2) in Fig. 1) into a room, or for discharging air drawn in from a room (e.g., indoor air) to the outside through the duct (2). Hereinafter, for convenience of explanation, a case in which the diffuser (1) discharges air drawn in from the duct (2) into the room will be described as an example.

[0024] For example, air discharged through the diffuser (1) can reduce the concentration of pollutants floating indoors. In addition, air discharged through the diffuser (1) can prevent pollutants existing in a certain space indoors from spreading to other spaces.

[0025] However, if the airflow discharged from the diffuser (1) is discharged in one direction or the speed of the air discharged from the diffuser is excessively fast, the ventilation performance may deteriorate or pollutants may easily spread to other spaces. Therefore, it is required to form a guide path for the airflow flowing inside the diffuser so that the external air discharged from the diffuser (1) is discharged in a uniform direction. The diffuser (1) described below can discharge the discharged air evenly in a certain direction at an appropriate speed.

[0026] FIG. 1 is a perspective view of a diffuser (1) according to one embodiment disclosed in this document.

[0027] Figure 2 is an exploded perspective view of a diffuser (1) according to one embodiment disclosed in this document.

[0028] Referring to FIGS. 1 and 2, the diffuser (1) may include a body (10), a damper (50), a rod (60), and a distribution plate (100).

[0029] According to one embodiment, the main body (10) can form the exterior of the diffuser (1). The main body (10) can be connected to a duct (2) extending horizontally (e.g., horizontally to the xy plane) to the ceiling. The duct (2) is illustrated as having a cylindrical shape, but is not limited thereto and can be implemented in various shapes. An opening can be provided in a predetermined area of ​​the main body (10) connected to the duct (2), and this can be referred to as an inlet (23) of the diffuser (1). Air discharged from the duct (2) can be introduced into the interior of the main body (10) through the inlet (23).

[0030] According to one embodiment, the main body (10) may include a first casing (20) and a second casing (30). The first casing (20) may be located on the upper side of the main body (10), and the second casing (30) may be located on the lower side of the main body (10).

[0031] According to one embodiment, the first casing (20) and the second casing (30) can be coupled. For example, the first casing (20) and the second casing (30) can be coupled by rotation. To this end, the first casing (20) and the second casing (30) can each include a coupling portion (e.g., the first coupling portion (21) and the second coupling portion (31) of FIG. 3). The inner side of the first coupling portion (21) and the outer side of the second coupling portion (31) are formed with corresponding screw threads, so that they can be coupled by rotation. The height of the main body (10) can be adjusted by the rotation of the first casing (20) and the second casing (30).

[0032] According to one embodiment, an inlet (23) may be formed on the side of the first casing (20) for introducing air discharged from the duct (2). An outlet may be formed on the lower part of the second casing (30) for discharging air into the indoor space.

[0033] According to one embodiment, the second casing (30) may include a plurality of stages arranged in a vertical direction. The plurality of stages may include, for example, a first stage (301), a second stage (302), a third stage (303), and a fourth stage (304). The first stage (301), the second stage (302), and the third stage (303) may have a cylindrical shape having a through hole. The fourth stage (304) may have a circular plate or flange shape with one end facing outward from the center. The first to fourth stages (301, 302, 303, 304) may be arranged sequentially from top to bottom (e.g., in the -z-axis direction).

[0034] According to one embodiment, the first to fourth stages (301, 302, 303, 304) may have a cross-sectional area in a horizontal direction (e.g., a direction parallel to the xy plane) that is wider toward the bottom. Accordingly, the cross-section of the inner wall of the second casing (30) may have a step shape.

[0035] According to one embodiment, a damper (50) may be placed at the lower portion of the main body (10). The damper (50) may open and close an exhaust port formed in the second casing (30). The damper (50) may be raised and lowered in a vertical direction (e.g., in the z-axis direction) by a rod (60) located at the upper portion.

[0036] According to one embodiment, the rod (60) is disposed inside the body (10) and can operate vertically to raise and lower the damper (50). The rod (60) may include a push latch (e.g., the push latch (65) of FIG. 8 or 9) configured to be raised and lowered by pressing. The structure and operation of the rod (60) and the push latch (65) included in the rod (60) will be described with reference to FIGS. 8 and 9.

[0037] In one embodiment, the load (60) may be coupled with a damper (50) disposed below. The damper (50) may include a coupling member (e.g., a third coupling member (54)) for coupling with the load (60). The third coupling member (54) may be coupled to the inside of the load (60).

[0038] In one embodiment, the rod (60) may be supported by a rib (70). The rib (70) may include an opening through which the rod (60) may pass. The rib (70) may be fixed to the inner wall of the body (10) to support the rod (60).

[0039] In one embodiment, the damper (50) can be rotatably coupled to the load (60). To facilitate rotation of the damper, the damper (50) can include a handle (51) located at the bottom. The handle (51) can rotate integrally with the damper (50). A user can adjust the height of the damper (50) by gripping and rotating the handle (51).

[0040] For example, the damper (50) may rise as it rotates in a predetermined direction (e.g., counterclockwise), and may descend as it rotates in a direction opposite to the predetermined direction (e.g., clockwise). Accordingly, the flow path of the diffuser (1) may be changed, and the direction of the airflow discharged through the outlet of the diffuser (1) may be changed. This will be described in connection with FIGS. 5 and 6.

[0041] According to one embodiment, the distribution plate (100) can distribute air flowing in from the inlet (23) in multiple directions. The distribution plate (100) can be positioned on the lower surface (25) of the first casing (20). The distribution plate (100) can be positioned in front of the inlet (23) to form a flow path so that the air bypasses the first casing (20) and then joins therewith. The air bypassed from the first casing (20) and then joined therewith can move to the second casing (30) and be discharged.

[0042] According to one embodiment, air flowing in from the inlet (23) may hit the distribution plate (100). The air may hit the distribution plate (100) and its velocity may be reduced, thereby controlling the velocity of the air.

[0043] According to one embodiment, the distribution plate (100) may be arranged symmetrically left and right with respect to the center. For example, the distribution plate (100) may be arranged so that the center of the distribution plate (100) and the center of the inlet (23) are in a straight line. By arranging the distribution plate (100) symmetrically left and right, the air introduced through the inlet (23) can be distributed at the same ratio.

[0044] According to one embodiment, the distribution plate (100) may have a curved shape. The distribution plate (100) may have a predetermined length (e.g., length l in FIG. 4), a predetermined height (e.g., height h in FIG. 10), and a predetermined thickness (thickness t in FIG. 10).

[0045] According to one embodiment, the distribution plate (100) may be composed of a plastic material. The distribution plate (100) may be injection molded.

[0046] According to one embodiment, the distribution plate (100) may include a pattern (e.g., a pattern (110a) of FIG. 11) or a slit (e.g., a slit (110b) of FIG. 12). The pattern (110a) may be formed by recessing at least a portion of the distribution plate (100). The slit (110b) may be formed by removing at least a portion of the distribution plate (100). The plurality of patterns (110a) or slits (110ab) formed on the distribution plate (100) may allow air reaching the distribution plate (100) to be efficiently distributed, or may minimize turbulent flow or eddy caused by air hitting the distribution plate (100) and control the flow rate of air flowing inside the diffuser (1). For example, when the velocity of air flowing into the inlet (23) is high, the velocity may decrease due to the air colliding with the distribution plate (100). The pattern (110a) or slit (110b) formed on the distribution plate (100) will be described in FIGS. 11 and 12.

[0047] FIG. 3 is a cross-sectional view of a diffuser (1) according to one embodiment disclosed in this document.

[0048] Referring to Fig. 3, the diffuser (1) of Fig. 1 can be understood as a cross-sectional view cut along the yz plane passing through the center of the duct (2) and the inlet (23). The configurations disclosed in Fig. 3 may correspond to at least some or all of the configurations disclosed in Figs. 1 and 2, and any description that overlaps with the above may be omitted.

[0049] The embodiment disclosed in FIG. 3 can be optionally combined with the embodiments disclosed in FIGS. 1 and 2.

[0050] According to one embodiment, the diffuser (1) may be arranged to be generally symmetrical left and right with respect to a central axis (e.g., an axis in the z-axis direction penetrating the center of the load (60)).

[0051] According to one embodiment, the main body (10) may include a first casing (20) and a second casing (30). The second casing (30) may be disposed below the first casing (20). The first casing (20) may be coupled to the second casing (30). For example, the first casing (20) and the second casing (30) may be coupled by rotation. A screw thread may be formed on a first coupling portion (21) included in the first casing (20) to correspond to a second coupling portion (31) included in the second casing (30). The coupling force of the first casing (20) and the second casing (30) may be strengthened by rotation, or the height may be adjusted. The position of the second casing (30) may be adjusted by adjusting the degree of rotation of the second casing (30) based on the height at which the first casing (20) is installed.

[0052] According to one embodiment, the second casing (30) may include a plurality of stages (301, 302, 303, 304) having a stepped shape. The plurality of stages (301, 302, 303, 304) may include a first stage (301), a second stage (302), a third stage (303), and a fourth stage (304). The first to third stages (301, 302, 303) may have a substantially hollow cylindrical shape, and the fourth stage (304) may have a disc shape (or flange shape) that is connected to an end of the third stage (303) and flares outward.

[0053] According to one embodiment, the first stage (301) may include a second coupling portion (31) so that the second casing (30) and the first casing (20) may be coupled. The diameter of the first stage (301) may have a length of p1, and the diameter p1 of the first stage (301) may be substantially equal to the diameter of the first coupling portion (21) of the first casing (20). In addition, a point corresponding to the height of the lowest end of the first stage (301) will be defined as q1.

[0054] According to one embodiment, the diameter of the second stage (302) may have a length of p2, and the diameter p2 of the second stage (302) may be substantially equal to the maximum diameter of the damper (50) described below. In addition, a point corresponding to the height of the lowest end of the second stage (302) will be defined as q2.

[0055] According to one embodiment, the diameter of the third stage (3030) may have a length of p3. In addition, the point corresponding to the height of the lowest end of the third stage (303) will be defined as q3.

[0056] According to one embodiment, the second casing (30) formed in a step shape can form a path that sequentially guides air to be discharged into the indoor space.

[0057] According to one embodiment, the damper (50) may be configured to open and close the outlet of the diffuser (1) by moving up and down in a vertical direction (e.g., in the z-axis direction), or may be configured to change the flow path of the diffuser (1) in an open state.

[0058] According to one embodiment, the damper (50) generally has a shape of a disc, and the damper (50) can be connected to the lower end of a rod (60) configured to be raised and lowered in a vertical direction. The damper (50) can include a third coupling portion (51) located on the upper side. The third coupling portion (51) can be connected to the inner side of an open end located on the lower side of the rod (60). The damper (50) is connected to the rod (60) and can move integrally in response to the raising and lowering of the rod (60).

[0059] In one embodiment, the rod (60) may be supported by a rib (70). The rib (70) may be fixed to the first portion (301) of the second casing (30), and at least a portion of the rod (60) (e.g., the lifting portion (64) of FIG. 8) may pass through an opening formed in the rib (70) and be positioned at the lower portion of the rib (70), and another portion of the rod (60) (e.g., the fixing portion (63) of FIG. 8) may be positioned at the upper portion of the rib (70) by being hung on the upper side of the rib (70).

[0060] According to one embodiment, the rod (60) may be positioned on the central axis of the diffuser (1). The rod (60) may have a predetermined diameter. The diameter of the rod (60) may be, for example, less than 1 / 3 of the length p1.

[0061] According to one embodiment, the damper (50) can be rotatably coupled to the rod (60), and the position of the damper (50) can be adjusted by rotation. To facilitate rotation of the damper (50), the damper (50) can include a handle (51) located at the bottom. For example, the damper (50) can rise as it is rotated in a predetermined direction (e.g., counterclockwise), and can descend as it is rotated in a direction opposite to the predetermined direction (e.g., clockwise). Accordingly, the flow path of the diffuser (1) can be changed, and the direction of the airflow discharged through the discharge port of the diffuser (1) can be changed. For example, the diffuser (1) illustrated in FIG. 3 (or FIG. 6) can transition to the state illustrated in FIG. 5 in response to the maximum rotation of the handle (51) in a predetermined direction (e.g., counterclockwise). Likewise, the diffuser (1) illustrated in FIG. 5 can transition to the state of FIG. 3 (or FIG. 6) in response to the maximum rotation of the handle (51) in a predetermined direction (e.g., clockwise).

[0062] According to one embodiment, the load (60) may include a latch member (e.g., latch member (65) of FIGS. 8 and 9) configured to be raised or lowered by pressing. The latch member (65) may be configured to move to a preset height in response to a spring (e.g., spring (655) of FIG. 9) being compressed or extended by pressing.

[0063] According to one embodiment, in response to a user pressing the lower portion of the damper (50) (e.g., the handle (51)), the rod (60) connected to the damper (50) can be raised and lowered to open and close the exhaust port. For example, the diffuser (1) in the state illustrated in FIG. 3 can close the second portion (302) of the second casing (30) in response to pressing the lower portion of the damper (50). That is, the diffuser (1) illustrated in FIG. 3 can transition to the state illustrated in FIG. 7 in response to pressing the lower portion of the damper (50). Similarly, the diffuser (1) illustrated in FIG. 7 can transition to the state illustrated in FIG. 3 in response to pressing the lower portion of the damper (50).

[0064] Fig. 4 is a plan view of a diffuser (1) viewed from above according to one embodiment of the present disclosure. Fig. 4 is a plan view of the diffuser (1) of Fig. 1 viewed from above, and for convenience of explanation, it can be understood as a drawing in which some components are seen through.

[0065] The embodiment disclosed in FIG. 4 can be optionally combined with the embodiments disclosed in FIGS. 1 to 3.

[0066] According to one embodiment, the distribution plate (100) may have a curved shape. The distribution plate (100) may be configured as a curved surface having, for example, a predetermined length (l), a predetermined height (e.g., height h in FIG. 10), and a predetermined thickness (e.g., thickness t in FIG. 10).

[0067] According to one embodiment, the distribution plate (100) may be arranged symmetrically left and right with respect to the center. The center may be understood as, for example, a point corresponding to the shortest distance at which air flows in from the inlet (23) and collides with the distribution plate (100).

[0068] According to one embodiment, the first casing (20) may have a circular shape when viewed from above, and the distance from the central axis of the diffuser (1) to the first casing (20) may be defined as R1. The embodiments disclosed in FIGS. 5 to 7 may be optionally combined with the embodiments disclosed in FIGS. 1 to 4. In addition, the first part of the second casing (30) (e.g., the first part (301) of FIG. 3) may have a circular shape when viewed from above, and the distance from the central axis of the diffuser (1) to the first part (301) may be defined as R2.

[0069] According to one embodiment, R1 and R2 may have a predetermined length relationship with p1 to p3 of FIG. 3.

[0070] For example, R1 is 0.75*p3 <R1<p3로 설정될 수 있다.

[0071] For example, R2 may be substantially equal to 0.5*p1.

[0072] According to one embodiment, the distance r from the central axis of the diffuser (1) to the distribution plate (100) is R2 <r<R1로 설정될 수 있다.

[0073] For example, r is, for example, 0.5*R1 <r<0.8*R1로 설정될 수 있다.

[0074] According to one embodiment, the distribution plate (100) may have an arc shape with a central angle of θ when viewed from above and a distance r from the central axis of the diffuser (1). The θ may be set to, for example, 90°<θ<180°.

[0077] FIG. 7 is a cross-sectional view of a diffuser (1) in a closed state according to one embodiment of the present disclosure.

[0078] FIGS. 5 to 7 illustrate a case where at least part or all of the diffuser (1) illustrated in FIG. 3 may correspond, and the discharge port is opened or closed corresponding to the position of the damper (50), or a first flow guide or a second flow guide is formed with the open discharge port. Therefore, overlapping content will be omitted and the differences will be mainly explained.

[0079] Referring to Fig. 5, the diffuser (1) can form a first flow guide. Here, the first flow guide can refer to a path formed so that air discharged from the diffuser (1) is discharged in a vertical direction.

[0080] According to one embodiment, the damper (50) can be lowered from a fixed rod (60) by the rotation of a handle (51) located at the bottom. The damper (50) can be lowered to a preset maximum point in response to the handle (51) being rotated in a predetermined direction (e.g., clockwise). To prevent the damper (50) from being detached from the rod (60) when lowered to the maximum point, a catch may be arranged on the lower side of the rod (60).

[0081] According to one embodiment, when forming the first euro guide, the damper (50) can be lowered to a point lower than point q3 by a predetermined height. The predetermined height may be set to, for example, 10 mm to 20 mm, but is not limited thereto, and may have a variety of ranges depending on the size of the diffuser (1).

[0082] According to one embodiment, when forming the first euro guide, air can be discharged into the indoor space along the internal space of the second casing, and the air discharged from the discharge port can be discharged in a vertical direction.

[0083] Referring to Fig. 6, the diffuser (1) can form a second flow guide. Here, the second flow guide can refer to a path formed so that air discharged from the diffuser (1) is discharged in a horizontal direction.

[0084] According to one embodiment, the damper (50) can be raised from a fixed rod (60) by the rotation of a handle (51) located at the bottom. The damper (50) can be raised to a preset maximum point in response to the handle (51) being rotated in a predetermined direction (e.g., counterclockwise). When the damper (50) is raised to the maximum point, a catch may be arranged on the upper side of the rod (60) to prevent the damper (50) from rising beyond the preset maximum point.

[0085] According to one embodiment, when forming the first euro guide, the damper (50) may be positioned at substantially the same height as point q3.

[0086] According to one embodiment, when forming the first euro guide, air can be discharged into the indoor space along the internal space of the second casing, and the air discharged from the discharge port can be discharged in a vertical direction.

[0087] According to one embodiment, the diffuser (1) illustrated in FIG. 6 can transition to the state illustrated in FIG. 5 in response to the maximum rotation of the handle (51) in a predetermined direction (e.g., counterclockwise). Similarly, the diffuser (1) illustrated in FIG. 5 can transition to the state illustrated in FIG. 6 in response to the maximum rotation of the handle (51) in a predetermined direction (e.g., clockwise).

[0088] According to one embodiment, the diffuser (1) can provide an optimized ventilation function based on the temperature conditions or humidity conditions of the indoor space by selectively forming the first flow guide or the second flow guide in response to the movement of the damper (50).
