Description

Ceiling type indoor unit of air conditioner

The present invention relates to a ceiling-type indoor unit of an air conditioner, and more particularly, to a ceiling-type indoor unit installed in a ceiling of an indoor unit.

Generally, an air conditioner is composed of a compressor, a condenser, an evaporator, and an inflator, and supplies air or warm air to a building or a room using an air conditioning cycle.

The air conditioner is structurally divided into a separable type in which the compressor is disposed outdoors and an integral type in which the compressor is integrally manufactured.

In the separate type, an indoor heat exchanger is installed in an indoor unit, an outdoor heat exchanger and a compressor are installed in an outdoor unit, and two devices separated from each other are connected to each other by a refrigerant pipe.

In the integrated type, the indoor heat exchanger, the outdoor heat exchanger and the compressor are installed in one case. The integrated type air conditioner includes a window type air conditioner for directly mounting the apparatus on a window, and a duct type air conditioner for connecting the suction duct and the discharge duct to the outside of the room.

The separate type air conditioner is generally classified according to the installation type of the indoor unit.

A stand-type air conditioner in which an indoor unit is vertically installed in an indoor space is referred to as a stand-type air conditioner. A wall-mounted type air conditioner in which an indoor unit is installed on a wall of the room is called a ceiling-type indoor unit.

There is also a system air conditioner which is capable of providing air-conditioned air in a plurality of spaces as one type of a separate type air conditioner.

In the case of a system air conditioner, there is a type in which a plurality of indoor units are provided to air-condition the room, and a type in which air-conditioned air is supplied to each space through the duct.

A plurality of indoor units provided in the system air conditioner may be equipped with a stand type, a wall type or a ceiling type.

The ceiling-type indoor unit according to the related art includes a case suspended from a ceiling wall, and a front panel covering a bottom surface of the case and installed on a ceiling-like surface.

A suction port is disposed at the center of the front panel, a plurality of discharge ports are disposed outside the suction port, and a discharge vane is provided for each discharge port.

However, if a failure occurs in the conventional discharge vane, there is a problem that the entire front panel must be detached from the case and then repaired. That is, conventionally, even if a failure occurs in any one of the plurality of discharge vanes, the entire front panel must be separated from the case, and then the failed discharge vane must be replaced or repaired.

The first module body 410 and the second module body 420 are closely attached to the bottom surface of the respective corner frames 313 and fastened through the fastening members 401 with respect to the vertical direction.

Therefore, the first module body 410 and the second module body 420 are disposed on the lower side of the front body 310. The first module body 410 and the corner frame 313 are arranged so as to face upward from the lower side and the second module body 420 and the corner frame 313 The fastening direction is also oriented from the lower side to the upper side.

With this structure, the entire vane module 200 can be easily separated from the front body 310 during the service process.

The vane module 200 is disposed at one side of the discharge port 102 and is located below the front body 310 and is connected to the first module body 310 detachably mounted to the front body 310 A second module body 420 disposed on the other side of the discharge port 102 and positioned below the front body 310 and detachably assembled to the front body 310 downwardly, One and the other of which are coupled to the first module body 410 and the second module body 420, respectively, and at least one of the first module body 410 and the second module body 420 is rotated relative to the first module body 410 and the second module body 420, A vane motor 230 installed in at least one of the first module body 410 and the second module body 420 to provide a driving force to the vane 210 and 220, 1 module body 410 and is disposed to face downward, and is formed to penetrate the first module body 410 A first fastening member 401-1 fastened to the front body 310 through the first fastening hole 403-1 and a second fastening member 401-1 fastened to the front body 310.

Particularly, since the first module body 410 and the second module body 420 are positioned below the front body 310, when the front body 310 is installed in the case housing 110, 200 can be separated from the front body 310. This is commonly applied to all four vane modules 200.

When the module body 400 is separated from the front body 310, the entire vane module 200 is separated to the lower side of the front body 310.

The first module body 410 includes a module body part 402 coupled to the front body 310 and a link mounting part 404 projecting upward from the module body part 402.

The module body 402 is fastened to the front body 310 by a fastening member 401 (not shown). The module body portion 402 may be coupled to the front body 310 through hook coupling or interference fit.

The permanent magnet 318 and the magnetic force fixing portion 328 are located above each grill corner portion 327 and are hidden by the respective grill corner portions 327.

&Lt; Separation process and assembly process of vane module >

If servicing is required for at least one of the four vane modules 200, the operator must first move the suction grille 320 downward.

When the suction grill 320 is moved downward, all of the module bodies 400 which are hidden by the suction grill 320 are exposed.

Then, the operator separates the fastening member 401 from the fastening hole 403 of the vane module 200 requiring service. Since the module body 400 is coupled to the front body 410 by the module hook 405, the vane module 200 does not fall even if the coupling members 401 and 403 are separated. Since the coupling of the vane module 200 does not depend entirely on the coupling member 401, there is no risk of a safety accident due to the falling of the vane module 200 even if the coupling member 401 is detached.

The operator can separate the entire module from the front body 310 by releasing the mutual engagement of the module hooks 405 of the module subject body 400 after the fastening member 401 is detached. The operator can then separate the cable (not shown) connected to the vane motor 230 from the separate vane module 200 and separate the entire one vane module 200 from the front body 310.

Since the vane module 200 is separated to the lower side of the front body 310, only the vane module 200 requiring service can be separated without removing the front body 310.

In addition, since the vane module 200 is coupled with the cable in addition to the coupling member 401 and the module hook 405, the coupling member 401 and the module hook 405 are not directly dropped to the floor even when the coupling member 401 and the module hook 405 are released. That is, even if the operator unintentionally drops the vane module 200 after the fastening member 401 and the module hook 405 are dismantled, the vane module 200 remains suspended from the cable.

After the separation of the vane module 200, the mounting process proceeds in the reverse order.

The cable and the vane motor 230 are connected to each other and then assembled to the front body 310 through the module hook 405 and the first module body 410 and the second module body 420 Are assembled to the front body 310, respectively. Then, the suction grill 320 is raised to the home position to complete the service.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is to be understood that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
