Description

DEVICE OF CONNECTING DIFFUSER < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a diffuser coupling device, and more particularly, to a diffuser coupling device that can connect a duct and a diffuser using a flexible duct.

Buildings used by residents for a certain number or more must be provided with air conditioning. The air conditioner can be installed by using a duct, and the duct means a passage through which air or wind can move during cooling and heating. The duct is connected to the diffuser so that air or wind in the duct can be introduced into the room. This diffuser may be connected to the connection socket and the flexible duct at the end of the duct.

Here, a diffuser may be provided in each inner chamber, and the provided diffuser allows air or wind to circulate in the inner chamber. However, air moving through the duct may contain dust or foreign matter, and such air may directly flow into the inner chamber. Therefore, the air or wind that enters the inner chamber must remove foreign matter or dust in the duct, and such a dust and foreign matter removing device is necessary. As a result, the diffuser may partially block the dust or foreign matter in the air by controlling the opening and closing of the air control plate to regulate the air flowing into the inner chamber, but it does not remove dust or foreign substances from the air by controlling the opening and closing state of the air control plate.

Also, since the duct is connected to each inner chamber, the noise generated in the inner chamber may move along the duct, thus requiring independence between the inner chambers. In some cases, the soundproofing material is provided in the duct, but since the soundproofing material protrudes from the inner surface of the duct, noise caused by the rubbing sound generated by the wind passing through the soundproofing material may occur through the duct.

The connection socket is formed by injection molding, and a hole through which air can pass can be formed in the connection socket. However, in order to form a hollow structure in the connection socket through injection molding, a member such as a core must be used, and the injection cost of the connection socket can be remarkably increased when the core is used. In addition, if the core is used in the injection molding, the size and width of the holes in the connection socket must be constant. As a result, there are many restrictions on the shape of the connection socket. For example, if the cross section of the duct is rectangular and the cross section of the flexible duct is circular, the connection socket will have to use other members such as a joint to connect each duct.

Flexible ducts must be cut according to the length of the building to be used. Flexible ducts are difficult to cut in the field due to the nature of materials made of PVC. have.

The present invention provides a diffuser connection device which is easy to connect and produce, and which can reduce the manufacturing cost.

The present invention provides a diffuser connection device capable of minimizing inter-room noise and capable of mounting a sound insulating material for noise reduction.

The present invention provides a diffuser coupling device that minimizes the movement of dust or foreign matter into the inner chamber or duct.

According to another aspect of the present invention, there is provided a diffuser connection apparatus comprising: a connection socket including a side inlet communicating with a main duct and a lower inlet through which air introduced into the main duct is vertically movable; A flexible duct including a first inlet coupled to the lower inlet and a second inlet positioned perpendicularly to the first inlet; And a diffuser communicating with the second inlet and including at least two filters for preventing vertical movement of dust and foreign matter introduced into the second inlet. According to the diffuser connection apparatus, it is possible to prevent foreign matter, dust and the like flowing through the duct from being introduced into the inner room, and to block the noise moving through the duct.

Here, the first filter may function to primarily filter dust or foreign matter introduced from the main duct and the flexible duct. The first filter may be formed in a net shape, and basically, large dust particles may block foreign matter. At this time, dust or foreign matter having a small particle size passes through the first filter, so that the second filter is provided to block the remaining dust and foreign matter.

The second filter can be formed of a sponge, a nonwoven fabric, or the like, and can block secondarily the foreign matter or dust not blocked by the first filter because the particles are denser than the first filter.

In addition, each duct can be connected to each inner chamber because it is a connecting passage connecting the diffuser. Thus, the noise generated from the inner room can be moved to another room along the duct. At this time, by providing the first and second filters, it is possible to block dust and foreign substances and to block the noise moving through the duct.

At this time, the first and second filters can be separated from the diffuser and can be used again by removing the dust by a method of shaking or washing. Therefore, the filter necessary for the diffuser connecting device can be semi-permanently used.

A through hole may be formed at the center of each filter, and the through hole may be inserted into the diffuser so that the filter can be supported and fixed. The support rod adjusts the opening and closing of the air regulating plate of the diffuser to adjust the amount of air supplied to the inner chamber.

Also, a soundproofing material may be provided inside the connection socket, and the soundproofing material may be formed using a sponge. In particular, the connection socket may include an upper connection socket for accommodating the upper half of the main duct and a lower connection socket corresponding to the upper connection socket.

On the other hand, the lower inlet of the connection socket may be formed perpendicular to the main duct, and the first inlet of the flexible socket may be formed in the same shape so as to be coupled to the lower inlet. As described above, when the downward inlet is formed in the same shape as the first inlet, the use of other members can be minimized and the connection socket and the flexible duct can be connected.

According to the embodiment of the present invention, the passage of dust or foreign matter introduced into the inner room can be blocked, and the inter-room noise can be prevented. At least two filters are provided in the diffuser to block dust and foreign substances entering through the main duct. In addition, each filter is designed to block noise moving between ducts, thereby maintaining independence between rooms.

According to the embodiment of the present invention, since the upper and lower cases of the connection socket can be separately formed, ducts of various sizes can be connected. Separate production of the upper and lower cases can produce the connection socket without using other members, thereby saving the time and manpower required for the connection socket production.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments. For reference, the same numbers in this description refer to substantially the same elements and can be described with reference to the contents described in the other drawings under the above-mentioned rules, and the contents which are judged to be obvious to the person skilled in the art or repeated can be omitted.

FIG. 3 is a perspective view illustrating a diffuser according to an embodiment of the present invention, and FIG. 4 is an exploded perspective view of the diffuser of FIG. 3. FIG. 5 is an exploded perspective view of the connection socket according to the embodiment of the present invention, and FIG. 6 shows the main part of FIG.

Referring to FIGS. 1 and 2, the diffuser connection apparatus 100 includes a main duct 120, a connection socket 140, a flexible duct 160, and a diffuser 180.

In the present embodiment, the diffuser connection apparatus 100 is a device for moving wind or air in a duct into a building in a building, and may be a connection passage through which wind or air can flow into the inner room through a duct and a diffuser. And, in some cases, may be a passage for discharging the air of the inner chamber to the outside. In addition, the main duct 120 generally refers to a duct used in a building, and the shape and structure to be formed can be changed according to required conditions, design specifications, and the like.

The connection socket 140 may be formed in a shape that can change the direction of the air or the wind introduced from the main duct 120. Referring to the drawing, the connection socket 140 includes a side inlet (not shown) that can communicate with the main duct 120 and includes a downward inlet 157 for vertically moving air introduced from the main duct 120, . ≪ / RTI > At this time, the downward inlet 157 may include a circular end portion and may protrude in the vertical direction. The lower inlet 157 may communicate with the end of a flexible duct 160 to be described later. Generally, since the flexible duct 160 is formed in a circular shape, the connection socket 140 and the flexible duct 160 The lower inlet 157 can be formed in a circular shape. In addition, if the downward inlet 157 is formed to protrude in the direction of the flexible duct 160, the downward inlet 157 can be fixed to the flexible duct 160. That is, after the connection socket 140 and the flexible duct 160 are mounted, the connection socket 140 and the flexible duct 160 can be fixed without using a member such as a SUS band.

One end of the connection socket 140 communicates with the main duct 120 and the downward inlet 157 is formed so that the air or wind in the main duct 120 can be vertically moved , The connection socket can be formed in a position to be changed according to the diffuser mounted in the inner chamber. Although the shape of the lower inlet 157 is circular as an example, the shape of the lower inlet may be changed according to the shape of the provided flexible duct, and the present invention is not limited to these.

Here, the connection socket 140 may include an upper connection socket 145 and a lower connection socket 155 of the main duct 120. The upper connection socket 145 and the lower connection socket 155 will be described in more detail below.

At the bottom of the connection socket 140 is provided a flexible duct 160 which is engaged with a downward inlet 157. The flexible duct 160 may include a first inlet 162 that may correspond to a lower inlet 157 of the connection socket 140 and may include a second inlet 164 to be perpendicular to the first inlet 162, As shown in FIG.

As described above, the flexible duct 160 can be connected to the lower inlet 157 of the connection socket 140. At this time, the lower inlet 157 can be coupled to the first inlet 162, and the first inlet 162 can be formed in the same shape as the width and size of the lower inlet 157, and the connection socket 140, It is desirable to make the binding of the first electrode 160 more rigid. If the first inlet 162 is formed in the same shape as the downward inlet 157, the air or wind flowing through the main duct 120 can be minimized.

The second inlet 164 may be formed at a position vertically corresponding to the first inlet 162 and may be connected to an end of the diffuser 180, which will be described later. The second inlet 164 may have the same shape as the first inlet 162, but may be larger than the first inlet 162 in some cases. This is because when the cross section of the second inlet 164 is formed larger than the cross section of the first inlet 162, air or air flowing through the flexible duct 160 is diffused to spread air evenly over the cross- It is because.

The second inlet 164 and the diffuser 180 are installed in the main duct 120 to diffuse the air introduced from the main duct 120 into the inner chamber. At this time, the filters 184, 186). In the embodiment of the present invention, the filters 184 and 186 built in the diffuser 180 are provided as two examples. However, in some cases, three or more filters 184 and 186 may be provided. The invention is not limited thereto. The provided filters 184 and 186 can primarily remove dust and foreign matter, and can secondarily block noise. The filter will be described in more detail below with reference to the drawings.

3 and 4, the diffuser 180 includes a diffuser body 182 on a base plate 188, at least two filters 184 and 186 in a diffuser body 182, And a support rod 190 that can fix and support the filters 184, 186.

The diffuser body 182 may be formed such that the cross section of the body becomes larger as it goes downward. This is because as the cross-section lower than the upper portion of the body 182 is larger, the air or the wind which is introduced from the duct is more smoothly spread, so that air can be spread evenly in the inner chamber.

At least two filters 184 and 186 may be incorporated in the diffuser body 182. In the embodiment of the present invention, an example in which the first filter 184 and the second filter 186 are incorporated is described, but the number of filters is not limited according to the demand of the inventor. The provided filters 184 and 186 may be formed to be detectable in the diffuser 180. The filters 184 and 186 can be easily replaced if the filters 184 and 186 are probable in the diffuser 180 and the filters 184 and 186 can be separated and replaced by the diffuser 180 when the repair of the diffuser 180 is required. 180) can be repaired.

At this time, the first filter 184 is formed of a plastic net, and can primarily block foreign matter and dust flowing into the inner chamber. Since the first filter 184 is formed in a net shape, basic dust and foreign matter can be removed, and the dust and foreign matter accumulated on the first filter 184 can be removed and washed out or reused.

The second filter 186 may be formed of a material having a relatively dense entry than the first filter 184 such as a sponge or a nonwoven fabric so as to secondarily block foreign matter or dust not blocked by the first filter 184 .

At this time, the second filter 186 can be reused when the dust accumulates in the same manner as the first filter 184, by removing or removing the dust. Therefore, since the filters 184 and 186 necessary for the diffuser connection apparatus 100 are semi-permanently used, the cost reduction and the user's reliability can be improved.

In addition, the main duct 120 can serve as a connecting passage connecting the inner chambers, so that the noise generated in the inner chambers can be transferred to the inner chambers. Soundproofing materials are provided in the ducts to prevent noise from moving into each of the inner chambers. However, since the ducts are difficult to replace, the soundproofing materials provided inside are also difficult to replace or repair. Accordingly, the first and second filters 184 and 186 may be installed in the main duct 120 to block noise or the like moving along the duct.

A through hole 192 may be formed at the center of each of the filters 184 and 186 and a support rod 190 capable of supporting and fixing the filters 184 and 186 in the diffuser body 182 may be inserted into the through hole 192. [ . The through hole 192 is formed in the base plate 188 and the air regulating plate and the filters 184 and 186 so that the base plate, the air regulating plate and the filters 184 and 186 are fixed to the diffuser body 182 I can do it.

Here, the support rod 190 can control the amount of air supplied to the inner chamber by adjusting the opening and closing of the air regulator (not shown) of the diffuser 180, and can pass through the base plate 188, the air regulating plate and the filters 184 and 186 So that it can be fixed with a fixing screw. Although not shown in the drawings, the air regulating plate may be provided in the diffuser body 182, and may be formed in various shapes such as a rotating blade, a closing plate, and the like so as to control an air inflow path.

In addition, the diffuser body 182 may include a support 181 to which the support rod 190 can be fixed. The support base 181 can serve as a center shaft for securing the support bar 190 and the screw between the support bar 190 passing through the base plate 188, the air regulating plate and the filters 184 and 186, .

Referring to FIGS. 5 and 6, the connection socket 140 may include an upper connection socket 145 and a lower connection socket 155.

The upper connection socket 145 may be connected to the main duct 120 and the lower connection socket 155 may be connected to the flexible duct 160. Since the connection socket 140 is formed separately by the upper connection socket 145 and the lower connection socket 155, mounting of the connection socket 140 can be facilitated.

The upper connection socket 145 and the lower connection socket 155 may be formed by injection molding and the shapes of the main duct 120 and the flexible duct 160 may be adjusted by adjusting the shape of the mold . For example, the cross-sectional area of the main duct and the flexible duct may not be the same, in which case a connector should be provided to allow the side inlet and the lower inlet of the connection socket to be fixed with each duct. However, since the connection socket can be formed according to the cross-sectional area of the duct when the connection socket 140 is formed through the injection of the mold, the apparatus and the apparatus can be more easily manufactured.

Referring again to the drawings, a sound insulating material 146 may be provided inside the upper connection socket 145. At this time, the upper connection socket 145 may be formed with the receiving groove 147 so that the sound insulating material 146 is provided, and the receiving groove 147 may be formed so as to protrude outward from the upper connecting socket 145 . The receiving groove 147 does not reduce the space inside the connection socket 140 even if the sound insulation material 146 is provided inside the connection, so that it does not affect the movement path of the air. Therefore, independence between the inner chambers can be ensured by the sound insulating material 146 without affecting the movement path of the air.
