Description

Technical Field

[0001] The present invention relates to a vent for ejecting air, such as installed on a vehicle roof, and more particularly, to a vent having a diffusing function, which allows a user to select an air discharge direction as direct ejection or diffusing ejection by providing a simple operation. Background Art

[0002] Vents for discharging cold air or warm air into a vehicle interior are provided on the instrument panel of a general vehicle. Recently, various forms of vent technologies applicable not only to the instrument panel but also to the vehicle roof have been disclosed.

[0003] Generally, a vehicle vent includes: a duct for guiding air into the interior; a plurality of inner vanes that rotate to guide the air discharge direction in the left - right direction; a plurality of outer vanes that rotate to guide the air discharge direction in the vertical direction; and a knob capable of rotating the inner vanes and the outer vanes.

[0004] The inner vanes are also referred to as vertical vanes and rotate in the left - right direction around hinges provided on the upper and lower sides; the outer vanes are also referred to as horizontal vanes and rotate in the vertical direction around hinges provided on the left and right sides.

[0005] However, for such a general vent, since air is directly ejected through a central air outlet, the ejection range is narrow, which causes the directly ejected air to directly contact the user, making the user feel cold rather than cool.

[0006] To solve the above problems, vent technologies that have been actively developed recently achieve indirect ejection and diffusion of air by providing holes along the edge of the central air outlet. In addition, vent technologies of circulation vents installed above the user's head to eject air have attracted much attention.

[0007] The vent technology using a diffusing air outlet has the advantage of achieving a more comfortable vehicle interior space by widely diffusing the directly ejected air.

[0008] However, in the currently disclosed vehicle roof vent technology, a knob component is directly provided at the diffusing air outlet part to independently open and close the diffusing air outlet. Therefore, since a separate intermediate cover component is required to install the knob component, there are problems such as low production efficiency of the product and frequent failures during operation.

[0009] Moreover, simply setting the diffusing air outlet on the outer edge of the central air outlet still causes air to be ejected in a straight line direction, so there is a limitation in the diffusing discharge effect of air.

[0038] Hereinafter, the present invention will be described with reference to the accompanying drawings. However, the present invention can be embodied in various different forms and is not limited to the embodiments described herein. Also, parts irrelevant to the description are omitted from the drawings to help clarify the description of the present invention, and like reference numerals are used for like parts throughout the specification.

[0039] Throughout the specification, when a part is referred to as being "connected to" another part, it includes not only "directly connected" but also "indirectly connected" with other parts intervening therebetween. Also, when a part is referred to as "including" a certain element, this does not mean excluding other elements than this element but can mean further including other elements, unless the contrary is specifically stated.

[0040] Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0041] Figure 1 is a perspective view of a ventilation port having a diffusion function according to an embodiment of the present invention; Figure 2 is Figure 1Stereogram of the vent with diffusion function observed from another direction; Figure 3 Exploded stereogram of the vent with diffusion function according to an embodiment of the present invention.

[0042] Hereinafter, the direction in which the vent of the present invention jets air will be referred to as the front direction or the external direction, and the direction opposite to the direction of jetting air will be referred to as the rear direction or the internal direction.

[0043] As shown in the figure, the basic structure of the vent with diffusion function according to an embodiment of the present invention may include a housing 100, an inner cover 300, a plurality of grille members 400, a link member 500, but may also include a wing spacer 200 installed between the housing 100 and the inner cover 300.

[0044] Figure 6 (a) and (b) of are stereograms showing the housing 100 observed from different angles according to an embodiment of the present invention.

[0045] The housing 100 is configured to have a frame 110, the rear surface of which is connected to a duct through which air flows, and the front surface of which is installed to be exposed on one side inside the vehicle. The frame 110 of the housing 100 may be formed in a circular shape as shown in the figure, or may be formed in various other shapes other than a circle, and according to an embodiment of the present invention, may include a first jet port 120 and a second jet port 130.

[0046] The first jet port 120 may be formed to penetrate the central portion of the frame 110 of the housing 100 so that air can be blown out in a straight line from a duct buried behind the vent of the present invention. On the contrary, the second jet port 130 may be configured as one or more holes penetrating the outer peripheral edge of the frame 110 of the housing 100 provided along the outer peripheral edge of the frame 110 of the housing 100 so that air can be diffused and blown out along the outward direction from the duct.

[0047] More specifically, the frame 110 of the housing 100 according to an embodiment of the present invention may have a first protruding frame 111 and a second protruding frame 112 protruding therefrom. The first protruding frame 111 protrudes to have a mounting protrusion 111a on its rear surface that can be fitted to one side of the vehicle, and the second protruding frame 112 protrudes to have an outer edge surface, and a plurality of second jet ports 130 pass through the outer edge surface at a position spaced inward from the first protruding frame 111.

[0048] In this case, the second jet port 130 according to an embodiment of the present invention may be formed to be inclined at a predetermined angle in the outward direction of the housing 100. This can make the outflowing air diffuse more efficiently in the outward direction, thereby more effectively realizing the diffusion function of the present invention. Various embodiments of the predetermined angle will be described in detail later.

[0049] The first ejection port 120 and the second ejection port 130 according to an embodiment of the present invention can be opened and closed simultaneously or selectively through a plurality of grille members 400 and wing spacers 200 described later. That is, the air flowing out from the pipeline buried in the vehicle can be discharged along a straight line through the first ejection port 120, and at the same time, can be discharged outwardly and dispersedly through the second ejection port 130, and each of the above air outflow paths can be independently selected.

[0050] The inner cover 300 can be circular corresponding to the outer shell 100, or other shapes, and the inner cover 300 encloses a part of the rear surface of the outer shell 100. The inner cover 300 can be formed to have a through central portion so that the air discharged from the pipeline buried in the vehicle flows to the outer shell 100.

[0051] The inner cover 300 is installed to have sufficient space between the outer shell 100 and the inner cover 300 for the wing spacer 200 to rotate. In this case, the inner cover 300 according to an embodiment of the present invention can further include a guiding groove with a predetermined depth to guide the rotation of the wing spacer 200.

[0052] Figure 8 Figures (a) and (b) show exploded perspective views of a plurality of grille members 400 and link members 500 observed from different angles according to an embodiment of the present invention.

[0053] The grille member 400 is arranged to enclose the first ejection port 120 in an openable and closable manner, and can be divided into a plurality of parts, so as to have a predetermined area enclosing the front surface of the first ejection port 120. Each grille member 400 can be installed to be hinge-connected to the inner edge surface of the first ejection port 120 or the inner edge surface of the first channel portion 220 described later, and rotate forward around a virtual axis passing through the first ejection port 120.

[0054] In other words, in a state where the plurality of grille members 400 close the first ejection port 120 in a surrounding manner, through a predetermined operation action provided by the user, each grille member 400 rotates forward around a virtual axis passing through the first ejection port 120, thereby opening the first ejection port 120.

[0055] The link member 500 is configured to connect a plurality of grille members 400 and enable the plurality of grille members 400 to rotate as a whole to open and close the first ejection port 120. As shown in the drawings, the plurality of grille members 400 have coupling devices 420 on their rear surfaces that can be coupled to the link member 500, and the link member 500 can be fitted to each of the plurality of coupling devices 420.

[0056] Figure 7Figures (a) and (b) are perspective views showing the wing spacer 200 observed at different angles according to an embodiment of the present invention.

[0057] The wing spacer 200 is installed to be rotatable by itself within the space provided between the outer casing 100 and the inner cover 300, and serves to open and close a plurality of second injection ports 130 formed along the outer peripheral edge of the outer casing 100.

[0058] As shown in the drawings, the wing spacer 200 according to an embodiment of the present invention has a main body portion 210 corresponding to the shape of the frame 110 of the outer casing 100, and may include a first passage portion 220 and a second passage portion 230 according to an embodiment of the present invention.

[0059] The first passage portion 220 may be formed to penetrate the central portion of the main body portion 210, thereby providing a flow path for air to flow linearly from the duct buried behind the ventilation opening of the present invention toward the first injection port 120. In contrast, the second passage portion 230 may be configured as one or more holes formed to penetrate along the outer peripheral edge of the main body portion 210, thereby providing a flow path for air to flow outward from the duct toward the second injection port 130.

[0060] More specifically, the main body portion 210 of the wing spacer 200 according to an embodiment of the present invention further includes a protruding main body portion 211 protruding to provide an outer peripheral surface through which a plurality of second passage portions 230 may penetrate. The protruding main body portion 211 is formed to be insertable into an open space formed on the inner wall of the second protruding frame 112 of the outer casing 100.

[0061] As described above, the main body portion 210 of the wing spacer 200 of the present invention is characterized in that the main body portion 210 is rotatable to open the plurality of second injection ports 130 in a range overlapping with the plurality of second passage portions 230.

[0062] On the one hand, the main body portion 210 of the wing spacer 200 according to an embodiment of the present invention may be fitted to the mounting device 430 protruding from the rear surface side of the plurality of grille members 400, so as to rotate integrally with the plurality of grille members 400. In other words, the user can rotate the main body portion 210 by providing a predetermined operating action to the grille members 400 externally, thereby opening and closing the second injection ports 130.

[0063] The grille member 400 according to an embodiment of the present invention may further include a protruding knob member 410 formed on its front surface for the user to hold. When the user holds the knob member 410, the user can provide a rotational movement to the wing spacer 200, wherein the wing spacer 200 and the grille member 400 are coupled together in an integrally rotatable manner.

[0064] In other words, the user can open and close the first ejection port 120 by applying a rotational motion in the front and rear surface directions to the grille member 400 exposed to the outside. Also, the user can open and close the second ejection port 130 by applying a rotational motion in the outward direction around an axis perpendicular to the front and rear surface directions.

[0065] As described above, the vent according to an embodiment of the present invention can provide an operation action to the grille member 400 instead of directly providing a knob on the wing spacer 200. Thus, the vent of the present invention can omit a separate intermediate member required for providing a knob on the outer peripheral edge portion of the wing member, thereby improving the productivity and economy of the product. In addition, the design outside the vent can be freely selected, and problems such as failures due to additional intermediate members do not occur.

[0066] Hereinafter, an operation method and various embodiments based on the above-described structure of the present invention will be described.

[0067] Figure 4 Figs. (a) and (b) are usage state diagrams based on the open / closed states of the second ejection port according to an embodiment of the present invention, and are shown as an enlarged view and a side view respectively; Figure 5 Figs. (a) to (c) are usage state diagrams of the first ejection port and the second ejection port of a vent having a diffusion function based on the open / closed states according to an embodiment of the present invention as viewed from the front.

[0068] Figure 4 Fig. (a) is a front view of the state where the second ejection port is closed and an enlarged side view of one side of the cross-section obtained along the Figure 4 cutting line A-A in (a). As shown, when there is no overlapping range between the plurality of second ejection ports 130 and the plurality of second channel portions 230 according to an embodiment of the present invention, the second ejection port 130 is closed, and air does not diffuse and discharge outward.

[0069] Figure 4 Fig. (b) is a front view of the state where the second ejection port is open, and an enlarged side view of one side of the cross-section obtained along the Figure 4 cutting line A'-A' in (b). As shown, when there is an overlapping range between the plurality of second ejection ports 130 and the plurality of second channel portions 230 according to an embodiment of the present invention, the second ejection port 130 is open, and the air discharged from the second channel portion 230 diffuses and discharges outward.

[0070] Figure 5(a) is the open mode of the vent according to an embodiment of the present invention, in which a plurality of grille members 400 are hinge-rotated in the front surface direction to open the first ejection port 120. At this time, the air from the duct is discharged directly and linearly through the first ejection port 120.

[0071] When the user wants to directly contact a large amount of air, that is, when the user hopes for direct ejection, the above open mode can be used.

[0072] Figure 5 (b) is the diffusion mode of the vent according to an embodiment of the present invention, in which a plurality of grille members 400 cover the first ejection port 120 to keep it closed, and the wing spacer 200 rotates so that the second ejection port 130 overlaps with the second channel portion 230, thereby opening the second ejection port 130. At this time, the air from the duct is discharged through the second ejection port 130 and diffuses in the outward direction of the vent.

[0073] When the user wants to indirectly contact a relatively small amount of air, that is, when the user hopes for indirect diffusion ejection, the diffusion mode can be used.

[0074] Figure 5 (c) is the close mode of the vent according to an embodiment of the present invention, in which the first ejection port 120 and the second ejection port 130 of the present invention are kept closed by a plurality of grille members 400 or wing spacers 200 respectively. At this time, the vent of the present invention does not discharge the air from the duct to the outside.

[0075] Figure 9 is a side view of the second ejection port 130 having a flow path with different angles according to an embodiment of the present invention; Figure 10 (a) to (c) are experimental data of an air flow meter on the air diffusion discharge effect of the second inclined flow path 132 with different angles according to various embodiments of the present invention.

[0076] As described above, the second ejection port 130 of the present invention can be formed to be inclined at a predetermined angle in the direction of the outer peripheral edge of the housing 100. Hereinafter, the angle formed by each second ejection port 130 according to various embodiments of the present invention will be described based on the angle formed with respect to the axis P perpendicular to the front surface of the vent of the present invention.

[0077] Figure 9 is along Figure 4 (b) is a side view based on the cross-section obtained along the cutting line A'-A'. As Figure 9As shown, the second ejection port 130 according to an embodiment of the present invention may include a first inclined flow path 131 and a second inclined flow path 132, and the first inclined flow path 131 and the second inclined flow path 132 have different inclination angles.

[0078] One end of the first inclined flow path 131 is connected to the rear surface of the housing 100 and provides a flow path for the air flowing in from the duct to flow in the outward direction. The first inclined flow path 131 is inclined at a predetermined angle θ1 from the central portion of the housing 100 toward the outer direction.

[0079] The second inclined flow path 132 is inclined at a predetermined angle θ2 from the central portion of the housing 100 toward the outer direction, and the inclined angle θ2 is different from the inclined angle θ1 of the first inclined flow path 131. One end of the second inclined flow path 132 is connected to the first inclined flow path 131, and the other end is exposed on the front surface of the housing 100 to discharge the air from the first inclined flow path 131 to the outside.

[0080] Meanwhile, the second inclined flow path 132 according to an embodiment of the present invention may be formed to be inclined such that the angle θ2 inclined from the central portion of the housing 100 toward the outer direction is smaller than the angle θ1 of the first inclined flow path 131 inclined from the central portion of the housing 100 toward the outer direction.

[0081] In still another embodiment, the second ejection port 130 may be inclined at an angle, whereby the first inclined flow path 131 and the second inclined flow path 132 form an S shape.

[0082] Based on the above-described structure, in the second ejection port 130 of the present invention, the first inclined flow path 131 may change the air flowing from the duct to the housing 100 through a steep inclination, and then the second inclined flow path 132 may change the air again through a gentle inclination. Therefore, the air can be appropriately diffused.

[0083] Figure 10 (a) to (c) are experimental examples of the air diffusion degree using an air flow meter, and respectively show the experimental results when the angle θ2 of the second inclined flow path 132 inclined from the central portion toward the outer direction is 60°, 15°, and 20°, respectively.

[0084] Referring to Figure 10 Referring to (a), it can be seen that when the angle θ2 formed by the second inclined flow path 132 of the present invention from the central portion toward the outer direction is 60°, the air diffuses and discharges too much through the second ejection port 130. In other words, at this angle, due to the too wide discharge range of the air, it is impossible to achieve an appropriate level of air discharge function required for the vehicle's vent.

[0085] Referring toFigure 10 In (b) and (c) of the figure, it can be seen that when the angles θ2 formed by the second inclined flow path 132 of the present invention from the central portion toward the outer direction are 15° and 20° respectively, the air is concentratedly discharged at a certain level or higher level, and at the same time, there is also a diffusion effect. In particular, when the angle θ2 formed by the second inclined flow path 132 from the central portion toward the outer direction is about 20°, the most appropriate discharge range is exhibited.

[0086] Based on the above experimental examples, the inclination angle θ2 of the second inclined flow path 132 from the central portion toward the outer direction according to an embodiment of the present invention can be 15° to 25°.

[0087] According to the various embodiments described above, the vent with a diffusion function of the present invention is installed on the roof, and the user can appropriately select direct discharge or diffusion discharge of air by providing a simple operation as needed.

[0088] Moreover, since there is no need to provide a separate intermediate component for providing the above operation, not only can productivity and economy be improved, but also the appearance design of the vent product can be freely selected.

[0089] The above description of the present invention is for illustrative purposes only. Those of ordinary skill in the art to which the present invention pertains should understand that the present invention can be easily deformed into other specific forms without changing the technical spirit or basic characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all aspects and not restrictive. For example, each component described in a separate form can be implemented in a dispersed form, and similarly, components described in a dispersed form can also be implemented in a combined form.

[0090] The scope of the present invention is defined by the claims hereinafter, and all changes or deformations obtained from the meaning, scope, and equivalent concepts of the claims should be interpreted as being included within the scope of the present invention.
