Description

A duct having a hole guard and a ventilation cushion device using the same {DUCT WITH HOLE GUARD AND VENTILATION CUSHION DEVICE USING THE SAME}

The present invention relates to a duct having a hall guard and a ventilation cushion device using the same.

The cushioning device includes an elastic material that is easy to compress and recover, such as a sponge. Cushion devices are being developed in various forms such as chair seats, sofas, vehicle seats, and bed mats. Various convenience functions are added to the cushion device. For example, cold/hot ventilation seats are applied to vehicle seats, and headrest and lumbar support adjustments, cold/hot cup holders, heating wires, USB ports, reading lights, Bluetooth/surround speakers, etc. can be added.

A plurality of vertical passages are formed in the cushion mat of the ventilation cushion device. Cushion mats can generally be made of sponge. In commercially available ventilation cushion devices, when used for a long time, vertical channels are narrowed or blocked, and the user may feel a foreign body sensation. In the case of existing ventilated seats, a flow path is provided as an “H” shaped groove in the cushion mat on the user's seating surface.

When a user sits on a ventilation cushion device, the vertical channels may be blocked due to the user's load. In order to improve this, a hole guard may be added to each of the vertical passages, but as the load applied to the ventilation cushion device increases and the use time increases, the hole guard is deformed and the vertical passages may be narrowed or blocked. When a user sits on a ventilation cushion device, a foreign body sensation may be felt.

Referring to FIG. 1 , a hole guard 30 according to an embodiment of the present invention includes a spring 10 and a spring support 20 .

The spring 10 may be implemented as a commercially available compression spring. For example, the spring 10 may be made of a metal coil spring as shown in FIG. 2A or a plastic molded spring as shown in FIG. 2B.

The hole guard 30 has a cylindrical structure with open top and bottom ends. The spring 10 of the hole guard 30 is inserted into a vertical hole penetrating the cushion mat 40 to define a vertical passage 42 . The cushion mat 40 may be made of a material having a high compressibility, for example, sponge. The spring 10 is manufactured with substantially the same diameter (or width) from the top to the bottom to fit the structure of the vertical passage 42 . Accordingly, the hole guard 30 has a hollow cylindrical structure due to the structure of the spring 10 . The inner space defined by the hole guard 30 becomes an actual vertical passage space.

A plurality of hall guards 30 may be disposed on the horizontal duct. In this case, the vertical flow path defined by each of the hall guards 30 is connected to the horizontal flow path in the horizontal duct, so that air introduced from the horizontal flow path can be discharged to the outside through the vertical flow path.

The spring support 20 has a cylindrical structure that supports the spring 10 from below and does not obstruct air flow in a vertical direction. The spring supports 20 are connected to the upper surface of the horizontal duct, which is not shown, by the number of springs 10 . A wide horizontal flow path is formed inside the horizontal duct. The horizontal passage of the horizontal duct is connected to the vertical passage defined by the hall guard 30 . The height of the spring support 20 may be set to about 10 to 20% of the height of the hall guard 30 .

When a user sits on the ventilation cushion device, the cushion mat 40 is compressed. At this time, the spring 10 is compressed along with the cushion mat 40 in the direction of the external force applied to the cushion mat 40 . When the user stands up, the cushion mat 40 and the spring 10 are inflated and restored.

The hall guard 30 is bent by the spring 10 compressed by an external force applied to the cushion mat 40 . At this time, the compressed spring 10 restrains the vertical flow path 42 in the radial direction (x, or width direction) of the vertical flow path 42 . Accordingly, the spring 10 may prevent a vertical channel formed in the cushion mat from being narrowed or blocked even when a load is applied to the cushion mat in any direction. Therefore, the ventilation cushion device of the present invention facilitates ventilation through the vertical passage even if the cushion mat is repeatedly compressed and restored and the cushion mat is deformed.

In the case where only the spring 10 is embedded in the vertical passage without covering, air may leak to the cushion mat 40 on the side of the vertical passage through a gap between twisted lines of the spring 10 when air flows in the vertical passage. . Therefore, there is a need for a method capable of blocking air leaking between the twisted wires of the spring 10 and maintaining the compression and restoring force of the spring 10 . To this end, the present invention implements a cylindrical hole guard 30 having compression and restoring force by covering the inside and outside of the spring 10 with natural/synthetic resin. As shown in FIG. 3 , the spring 10 may be covered inside and outside of the spring 10 with a soft natural/synthetic resin, such as latex or silicone synthetic rubber. The spring 10 covered with a soft material blocks air leakage in the radial direction (x, y, or width direction) of the vertical flow path 42 to increase ventilation efficiency. Hereinafter, the spring 10 covered with a soft material will be referred to as a “spring part”.

As shown in FIGS. 4A and 4B , the spring unit 300 has a cylindrical structure including a spring 10 and a coating 22 covering the inside and outside of the spring 10 . The lower end of the spring part 300 may be coupled to the spring support part 20 in a simple fitting form. The inner diameter of the spring part 300 is slightly larger than the outer diameter of the spring support part 20, or the outer diameter of the spring part 300 is It may be set slightly smaller than the inner diameter of the spring support 20 .

An upper end of the hole guard 30 including the spring part 300 may include a flange 24 shown in FIG. 4B. The flange 24 widely spreads outward from the upper outer circumferential surface of the hole guard 30 . The upper center of the hall guard 30 is open so as not to disturb the air flow in the vertical passage. The flange 24 not only stably fixes the upper end of the spring part 300 to the upper surface of the cushion mat 40, but also covers the upper surface of the cushion mat 40 widely to avoid debris generated on the upper surface of the cushion mat 40. Falling into the vertical passage 42 can be prevented.

At least a portion of the sheath 22 of the spring unit 300 may include bellows, as shown in FIG. 4C .

When a user sits or lies on a sofa, seat, or bed, the cushion mat 40 is compressed and expanded only in the vertical direction. Therefore, since the ventilation cushion device moves up and down only by a user's load, the spring part 300 and the spring support part 20 can be coupled by simple fitting in the vertical direction without a complicated fastening structure as shown in FIG. 5 .

In FIG. 5 , a plurality of spring supports 20 are connected to the upper surface of the horizontal duct 200 . An inlet pipe 21 may be formed on the lower surface of the horizontal duct 200 . A wide horizontal passage connected to the vertical passages is formed inside the horizontal duct 200 .

The inlet pipe 21 is formed on the lower surface of the horizontal duct 200 to define an air inlet 221 connected to a horizontal flow path in the horizontal duct 200 . The inlet pipe 21 may be connected to an air conditioner. The air conditioner may include a blower 50 and a thermoelectric module (TEM) 52. The thermoelectric element 52 generates cold or warm air by using endothermic and exothermic reactions generated in different elements to which voltage is applied. The blower 50 supplies cold or warm air to the internal horizontal passage of the horizontal duct 200 . The thermoelectric element 52 and the blower 50 may be controlled through a user interface omitted from the drawing, for example, a remote controller. Accordingly, the user may adjust the temperature, airflow amount, and the like of the ventilation cushion device through the user interface.

The spring part 300 may be coated with a soft material using the mold shown in FIG. 6 .

Referring to FIG. 6 , the mold may be divided into first and second molds 60 and 62 . The first mold 60 and the second mold 62 may be spaced apart from each other by the thickness of the spring covered by the soft material in the hole guard 30 .

The first mold 60 includes a core hole defining the external shape and size of the spring part 300 . The second mold 62 is a core mold that is inserted into the core hole of the first mold 60 to define the inner shape and size of the spring part 300 . In the injection space between the second mold 62 and the core hole of the first mold 60, there is a gap corresponding to the thickness of the spring part 300, for example, a gap of about 1 to 2 mm.

After the spring 10 is inserted into the injection space between the molds 60 and 62, the resin raw material 23 for coating is injected. When the mold temperature is lowered and a predetermined time elapses, the resin raw material 23 covering the inside and outside of the spring 10 is hardened. At this time, the spring part 300 is separated from the molds 60 and 62 .

7 is a cross-sectional view showing a duct structure according to an embodiment of the present invention. 8 is a view showing a cell division structure of a duct according to an embodiment of the present invention.

Referring to FIGS. 7 and 8 , the horizontal duct 200 may be divided into an upper plate 210 and a lower plate 220 .

A horizontal passage 230 is provided between the upper plate 210 and the lower plate 220 . The horizontal flow path 230 is connected to vertical flow paths defined by the plurality of spring supports 20 formed on the top plate 210 .

The top plate 210 includes a plurality of hole guards 30 . The hole guards 30 include spring parts 300 respectively coupled to the spring support parts 20 .

The lower plate 220 includes an air inlet 221 defined by the inlet pipe 21 , a plurality of embossings 224 , and a plurality of spacers 225 .

The protrusions 224 protrude to a low height from the inner lower surface of the horizontal duct 200 within the horizontal passage 230 . The protrusions 224 separate the air flow in the horizontal flow path 230 in various directions by using the Venturi effect that speeds up the air flow within the horizontal flow path 230 so that air flows through the entire horizontal flow path 230. spread widely. Accordingly, the protrusions 224 evenly distribute the air introduced through one air inlet 221 to the widely distributed hole guards 30 on the horizontal duct 200 . The spacers 225 protrude from the inner lower surface of the horizontal passage 200 at a height higher than the protrusions 224 to secure the height of the horizontal passage 230 .

The upper plate 210 and the lower plate 220 of the horizontal duct 200 may be made of the same material or different materials. The upper plate 210 and the lower plate 220 are coupled to face each other to define the horizontal passage 230 . For example, the upper plate 210 and the lower plate 220 may be molded into an integrated structure using an injection molding process or may be bonded with an adhesive. In addition, the upper plate 210 and the lower plate 220 may be assembled in a detachable structure.

The horizontal duct 200 preferably has a structure that is flexibly bent in the horizontal and vertical directions when the ventilation cushion device is deformed due to a user's load. To this end, the horizontal duct 200 may be divided into a plurality of cells 212 and 222 partitioned along the horizontal and vertical directions (x, y) as shown in FIG. 8 . The cells 212 of the upper plate 210 and the cells 222 of the lower plate 220 face each other with the horizontal passage 230 interposed therebetween. The boundaries 213 and 223 between the cells 212 and 222 have a wrinkled structure that is easily bent. For example, as shown in FIG. 9 , each of the upper board boundary 213 and the lower board boundary 223 may be bent in a concave or convex shape and may include pleats of a bellows structure. A horizontal passage 230 is connected between adjacent cells 212 and 223 between the upper plate boundary 213 and the lower plate boundary 223 . Accordingly, it should be noted that the air flow of the horizontal passage 230 is not blocked at the boundaries 213 and 223 between the cells 212 and 222 of the horizontal duct 200 .

11A and 11B are views showing changes in the horizontal duct 200 before and after a user sits when the horizontal duct 200 is divided into a plurality of cells in the ventilation cushion device according to an embodiment of the present invention.

Referring to FIGS. 11A and 11B , the horizontal duct 200 may be disposed below the cushion mat 40 .

A plurality of hall guards 30 are coupled to the upper surface of the horizontal duct 200 . Each of the hole guards 30 is inserted into vertical holes of the cushion mat 40 to define vertical channels 42 .

As shown in FIG. 11A , the horizontal duct 200 may be installed in a ventilation cushion device in a convex shape. When a user sits on the ventilation cushion device, as shown in FIG. 11B , the cushion mat 40 is compressed by the user's load, and the cushion mat 40 and the horizontal duct 200 are bent concave downward. At this time, as the cushion mat 40 is compressed when the user sits down, the vertical passage 42 and the hall guard 30 formed in the cushion mat 40 are also compressed, but the vertical passage is caused by the spring 10 of the hall guard 30. Since 42 is not narrowed or blocked, the flow of air blown to the user through the horizontal duct 200 and the vertical flow passages 42 is smooth.

The cell division structure of the horizontal duct 200 can flexibly bend the horizontal duct 200 in response to the sofa suspension 46 requiring high cushioning. Since the suspension 46 bends or bends under user seating pressure, it is preferable that the horizontal duct 200 also have a cell structure to flexibly respond to changes in the shape of the suspension 46 . If the horizontal duct 200 is implemented as a hard case without being divided into a cell structure, the horizontal duct 200 cannot be installed in the sofa including the subsection 46, and the horizontal duct 200 is damaged or damaged during long-term use. of the horizontal flow path may collapse.

The ventilated cushion device according to an embodiment of the present invention can be applied to various cushion devices such as chair seats, sofas, vehicle seats, and bed mats. In order to apply a ventilation cushion device to a sofa, a method of forming a plurality of vertical passages penetrating the cushion mat 40 to allow air to flow toward the user may be considered. In the case of a sofa, the compression rate of the sponge used as the cushion mat 40 is high. For this reason, when a user sits on the seating surface of the sofa, the cushion mat 40 is compressed a lot, and the vertical flow path collapses and is easily clogged or narrowed. According to the present invention, by inserting the hole guards 30 into the vertical holes penetrating the cushion mat 40, even if the cushion mat 40 is completely compressed, the phenomenon of narrowing of the vertical passages 42 can be prevented and ventilation efficiency can be improved. there is. When the cushion mat 40 is compressed, the spring portion 300 of the hall guard 30 is compressed in conjunction with the cushion mat 40, so that the user can sit on the sofa without feeling foreign body.

The cushion mat 40 is made of a relatively thick sponge and placed on the elastic band 45 and the suspension 46. The insect repellent 43 may include a drug that sterilizes insects such as mites, bacteria, and viruses. A cushion supplement 41 may be added between the cushion mat 40 and the insect repellent 43 to improve cushioning properties. The cushion supplement 41 may include a material such as cotton, bird feather, or non-woven fabric.

In the case of the sofa as shown in FIGS. 12 and 13, the cushion layers 40, 41, and 43 are compressed and bent downward by the weight of the user when the user sits on them, and the cushion layers 40, 41, and 43 interlock with the suspension. (46) and the elastic band (45) are bent down. When the user stands up, the cushion layers 40, 41, and 43 expand and return to their original positions due to the restoring force of the suspension 46 and the elastic band 45.
