The module body 400 is integrally installed on the front panel 300. That is, the entire components of the vane module 200 are modularized and installed on the front panel 300 at once.

Since the vane module 200 is modularized, it is possible to shorten the assembly time, and has an advantage of easy replacement in case of a failure.

In this embodiment, the vane motor 230 is a step motor.

<Configuration of module body>

The module body 400 may be configured as one body. In this embodiment, to minimize the installation space and to minimize the manufacturing cost, it is manufactured by separating into two parts.

In this embodiment, the module body 400 is composed of a first module body 410 and a second module body 420.

The first module body 410 and the second module body 420 are formed symmetrically. In this embodiment, a common configuration will be described using the first module body 410 as an example.

<Separation and assembly process of vane module>

When service is required for at least one vane module 200 among the four vane modules, the operator must first move the suction grill 320 downward.

When the suction grill 320 is moved to the lower side, all module bodies 400 that are hidden in the suction grill 320 are exposed.

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

After the fastening member 401 is removed, the operator can separate the entire vane module 200 from the front body 310 by releasing the interlocking of the module hook 405 of the module body 400 to be separated. Thereafter, the operator can separate the cable (not shown) connected to the vane motor 230 from the separated vane module 200, and can separate the entire vane module 200 from the front body 310.

Since the vane module 200 is separated under 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 to the cable in addition to the fastening member 401 and the module hook 405, the fastening member 401 and the module hook 405 are not dropped directly to the floor even when released. That is, even if the operator accidentally drops the vane module 200 after the fastening member 401 and the module hook 405 are disassembled, the vane module 200 remains suspended from the cable.

After the vane module 200 is removed, the mounting process proceeds in reverse order.

After connecting the cable and the vane motor 230, it is assembled to the front body 310 through the module hook 405, and the first module body 410 and the second module body 420 through the fastening member 401 ) Are assembled to the front body 310, respectively. Then, the suction grill 320 is raised to its original position to complete the service.
