In addition, a second connection member 400 is provided to connect between the outlet 112 and the exhaust duct 220 . The first connecting member 300 and the second connecting member 400 have substantially the same structure. Hereinafter, the structures of the first connecting member 300 and the second connecting member 400 will be described.

2 and 3 , the first connection member 300 is supported at the end of the intake duct 210 . Since the second connecting member 400 (refer to FIG. 1) has substantially the same structure as the first connecting member 300, a description thereof will be omitted. In the following embodiments, for simplicity, the first connecting member 300 is referred to as a connecting member 300 , and the intake duct 210 is referred to as a duct 210 .

The duct 210 may be provided in a structure in which a wire extending in the form of a spring supports a hose made of a material such as, for example, fiber. In this case, since the length of the duct 210 can be reduced by using a wire, the transport of the duct 210 is convenient. However, this structure is only one example of the duct 210 , and the duct 210 may have various structures within a range capable of forming a flow path. For example, the duct 210 may be implemented as a flexible hose including a rubber or resin material. The duct 210 has a flow path through which air moves, and both ends of the flow path are communicated so that air can be sucked in or discharged through the corresponding flow path.

The connecting member 300 includes a connecting member body 310 supported on the flow path end of the duct 210 . A hole 320 is formed through the center of the connection member body 310 , and the connection member body 310 is supported in the duct 210 so that the hole 320 communicates with the end of the flow path of the duct 210 . The connection member body 310 may include various materials such as plastic, resin, and metal. The method in which the connecting member body 310 is supported by the duct 210 is not limited and various configurations are possible. For example, in a state in which the end of the duct 210 covers the outer circumferential surface of the connecting member body 310 , the outer circumferential surface of the end of the duct 210 covering the connecting member body 310 may be clamped.

The connecting member 300 includes a fin 330 extending a predetermined length in a radial direction from the outer circumferential surface of the connecting member body 310 . When the connecting member 300 is connected to the opening 111 (refer to FIG. 1 ) of the housing 110 (see FIG. 1 ), the pin 330 contacts the outer surface of the housing so that the connecting member 300 moves into the housing 110 . prevent full entry.

The connecting member 300 is provided on the connecting member body 310 and includes a coupling portion provided to be connected to or disconnected from the housing 110 (refer to FIG. 1 ). Various design methods may be applied to the coupling unit, and this embodiment is only one example among them. The coupling part has a locking shape and includes a locking part 340 provided to be in a locking state in the housing 110 (see FIG. 1 ) when the connection member 300 and the housing 110 (see FIG. 1 ) are connected.

The connecting member body 310 has a free end 311 that can be elastically deformed toward the center of the connecting member body 310 by an external force, and the engaging portion 340 protrudes on the outer surface of the free end 311 . do. The free end 311 is formed by cutting off a part of the outer peripheral surface of the connecting member body 310, and elastically movable along the radial direction of the connecting member body 310 with respect to the fixed end, which is the remaining area of the connecting member body 310. arranged to do In this embodiment, it is shown that each is installed on the left and right sides of the connecting member body 310, the installation position and number of the engaging portion 340 is not limited.

The front surface facing the housing from the locking part 340 is provided to be inclined at a predetermined angle from the connecting member body 310 . Accordingly, when an external force is applied in the direction toward the housing, the front surface of the locking part 340 comes into contact with the edge of the opening of the housing and slides so that the locking part 340 enters the opening of the housing. On the other hand, the rear surface facing the duct 210 from the engaging portion 340 is provided to stand substantially perpendicular to the connection member body (310). Accordingly, once the locking part 340 passes through the opening of the housing, the locking part 340 is caught on the edge of the housing opening, so that the connecting member 300 is not easily removed from the housing.

The connection member 300 includes a lock release part 350 that operates the lock part 340 to release the lock part 340 from the housing when the connection member 300 is disconnected from the housing. do. The lock release unit 350 is provided on the outer surface of the free end (311). When the external force acts in the central direction of the connecting member body 310, the locking part 350 elastically deforms the free end 311 in the corresponding direction so that the locking part 340 can be separated from the edge of the opening of the housing. . On the other hand, the lock release unit 350 is disposed within a range within a distance reachable by the user's hand in a state of gripping the holding unit 360 from the mounting unit 360 to be described later. Accordingly, it is possible for the user to more easily attach and detach the connection member 300 .

The connecting member 300 includes a mounting portion 360 provided on the outer circumferential surface of the connecting member body 310 for temporary mounting while connected to the duct 210 during installation of the air conditioner. The mounting part 360 has a mounting shape corresponding to the structure of the ceiling 10 (refer to FIG. 1 ) in which the body 100 (refer to FIG. 1 ) is embedded, for example, the ceiling opening 40 (refer to FIG. 1 ).

Hereinafter, the structure and method of use of the mounting unit 360 will be described.

4 is a side view showing the connection member viewed from the side.

As shown in FIGS. 4 and 5 , the connecting member 300 includes a mounting part 360 provided on one side of the connecting member main body 310 . The mounting part 360 is provided to correspond to the shape of the edge of the ceiling opening 40 of the ceiling 10 in which the body of the air conditioner is embedded. When the body is not embedded in the ceiling 10 , the user mounts the connecting member 300 to which the duct 210 is coupled to the ceiling opening 40 by the mounting part 360 . Accordingly, the user can facilitate the operation of installing the main body and connecting the duct 210 to the installed main body.

The mounting portion 360 includes a first extension portion 361 extending to protrude from the outer surface of the connection member body 310 , and a second extension portion 361 bent from the first extension portion 361 and extending in the direction of the duct 210 . an extension 362 . The first extension 361 and the second extension 362 may have a predetermined curvature or may be in contact with each other to be substantially orthogonal to each other. A space is formed between the connecting member body 310 , the first extension part 361 , and the second extension part 362 , and the edge of the ceiling opening 40 is accommodated in this space. Accordingly, the connecting member 300 and the duct 210 are mounted on the edge of the ceiling opening 40 of the ceiling 10 by the mounting part 360 . When the user from the lower side of the ceiling 10 pushes the connecting member 300 in the direction of the ceiling opening 40 by using the mounted mounting unit 360 , the connecting member 300 including the mounting unit 360 and the duct 210 is separated from the edge of the ceiling opening (40).

The length W1 of the first extension part 361 from the outer surface of the connecting member body 310 to the point where it is bent to the second extension part 362 corresponds to the thickness W2 of the ceiling 10 in which the air conditioner body is embedded. do. Specifically, W1 is provided to be larger than W2 by a predetermined distance, thereby stably supporting the connecting member 300 to the ceiling opening 40 , while allowing the user to easily detach the holder 360 from the ceiling opening 40 . provided so that

On the other hand, the distance W3 between the holding unit 360 and the lock release unit 350 is provided within a range that can be reached by the user's hand in a state of gripping the mounting unit 360 . Accordingly, the connection member 300 connected to the main body can be easily disconnected from the main body by the user with one hand.

Hereinafter, a method in which the engaging portion of the connecting member is coupled to the housing of the main body will be described.

As shown in FIG. 6 , the housing 110 of the main body has an opening 111 formed on one side thereof, and an area of the inner surface of the housing 110 forming an edge of the opening 111 has a locking support 114 . to form The locking support part 114 is in a locking state with the locking part 340 when the housing 110 and the connecting member 300 are connected. In the connection member 300 , a locking part 340 is provided on the free end 311 . The locking part 340 has a locking shape corresponding to the locking support part 114 .

In this figure, the X direction is a direction toward the opening 111 of the housing 110 , and the -X direction is the opposite direction and indicates a direction toward the duct. The Y direction is a radial direction of the connecting member 300 , and the -Y direction is the opposite direction and indicates a direction toward the center of the connecting member 300 . The X direction and the Y direction are orthogonal to each other.

The connecting member 300 includes a first position P1 not connected to the housing 110 , a second position P2 in which the engaging portion 340 contacts the edge of the opening 111 , and the engaging portion 340 . It may be in any one position of the third position (P3) supported by the engaging support (114). The connecting member 300 of the first position (P1) moves in the X direction by an external force, and by moving to the third position (P3) after passing the state of the second position (P2), the connecting member 300 is moved to the housing ( 110) is connected.

The engaging part 340 has a first engaging surface 341 facing the X direction, and a second engaging surface 342 facing the -X direction in contact with the first engaging surface 341 . The first locking surface 341 is provided to be inclined with a predetermined angle between 0 degrees and 90 degrees with respect to the axis in the -X direction. In contrast, the second locking surface 342 is substantially orthogonal to the axis of the -X direction.

When the connecting member 300 moving in the X-direction passes through the second position P2, the first engaging surface 341 of the engaging part 340 in the housing 110 forming the edge of the opening 111 is contact Since the first locking surface 341 is provided to be inclined at a predetermined angle, an external force acts in the -Y direction by the contacting housing 110 . The external force acting in this way pushes the free end 311 in the -Y direction, and the free end 311 is bent in the -Y direction. As the external force in the X direction and the external force in the -Y direction act on the engaging portion 340 together, the first engaging surface 341 slides on the housing 110, and the connecting member 300 is located in the third position ( Move to P3).

When the connecting member 300 reaches the third position P3, the external force by the housing 110 is released, so that the free end 311 returns to the original position. The second locking surface 342 of the locking part 340 faces the locking support part 114 , and the locking part 340 is supported by the locking support part 114 . At this time, even if an external force acts on the connecting member 300 in the -X direction, the connecting member 300 does not separate from the housing 110 because the engaging portion 340 is caught by the engaging supporting portion 114 .

In order to separate the connecting member 300 at the third position P3 from the housing 110 , the free end 311 must be bent in the -Y direction so that the engaging part 340 can exit the opening 111 . . When the user presses the lock release unit 350 (refer to FIG. 2 ), the free end 311 is bent in the -Y direction. As the connecting member 300 moves in the -X direction while maintaining this state, the connecting member 300 may move to the first position P1.

Hereinafter, a process in which the user installs the air conditioner body will be described.

Each process of FIGS. 7, 8, 9 and 10 is sequentially performed.

As shown in FIG. 7 , the ceiling 10 is perforated in order to embed the main body of the air conditioner in the ceiling 10 , thereby providing a ceiling opening 40 . The ceiling opening 40 is at least larger than the size of the main body so that the main body can be raised from the lower side of the ceiling 10 to the upper side of the ceiling 10 , for example.

When the duct 210 extends from a predetermined place to the ceiling opening 40 through the upper side of the ceiling 10 , the connection member 300 is coupled to the duct 210 . The coupling method of the connection member 300 and the duct 210 is not limited, but the hole of the connection member 300 communicates with the flow path of the duct 210 . For example, the connecting member 300 may be coupled to the duct 210 by a clamping method.

As shown in FIG. 8 , the connecting member 300 coupled to the duct 210 is supported at the position of the ceiling opening 40 by the mounting part 360 being mounted on the edge of the ceiling opening 40 . Since the duct 210 extends to a predetermined place where air is introduced or discharged, the weight also increases according to the extended length. For this reason, tension may be applied to the duct 210 in a direction away from the ceiling opening 40 . The mounting part 360 overcomes this tension and supports the connecting member 300 and the duct 210 to the edge of the ceiling opening 40 .

If the connecting member 300 does not have the mounting part 360 and it is desired to support the duct 210 at a position close to the ceiling opening 40 , the duct 210 is connected to the ceiling 10 through the ceiling opening 40 . It should hang down long. In this case, the length of the duct 210 is increased by the length of the ceiling 10 hanging down, and the flow path of the air moving the duct 210 is also increased. In the connection member 300 according to the present embodiment, since the mounting portion 360 is applied, the length of the duct 210 can be prevented from being increased in this way.

As shown in FIG. 9 , the main body 100 is installed so as to be embedded in the upper side of the ceiling 10 from the lower side of the ceiling 10 through the ceiling opening 40 . While the main body 100 is installed on the ceiling 10 , the connecting member 300 and the duct 210 are supported at the edge of the ceiling opening 40 by the mounting part 360 . When the main body 100 is installed, the opening 111 of the main body 100 and the connecting member 300 are disposed to face each other.

The user grips the holder 360 supported by the edge of the ceiling opening 40 from the lower side of the ceiling 10 and pushes it in the direction of the main body 100 . Accordingly, the front end of the connecting member 300 provided with the engaging portion 340 passes through the opening 111 and moves. As the engaging portion 340 is caught on the inner surface of the main body 100 , the connecting member 300 covers the opening 111 and is supported to be connected to the main body 100 .

As shown in FIG. 10 , as the main body 100 and the connecting member 300 are connected, the flow path in the duct 210 communicates with the main body 100 . As the pin 330 of the connecting member 300 contacts the outer surface of the main body 100 , the connecting member 300 is further prevented from entering the inside of the main body 100 .

According to this process, the connecting member 300 may connect the main body 100 and the duct 210 .

In the above embodiment, the case where the position of the opening 111 provided in the main body 100 is the side surface of the main body 100 has been described. In this case, since the position of the opening 111 faces the connection member 300 mounted on the ceiling opening 40, installation is possible according to the above-described process.

However, if the location of the opening is on the top surface rather than the side of the body, the installation process is slightly different. Hereinafter, such an embodiment will be described.

As shown in FIG. 11 , the ceiling 10 is perforated in order to embed the main body of the air conditioner in the ceiling 10 , thereby providing a ceiling opening 510 . The connecting member 300 coupled to the duct 210 is supported on the edge of the ceiling opening 510 by the mounting part 360 being mounted on the edge of the ceiling opening 510 .
