<Door assembly-Discharge port cover>

The discharge port cover 25 is a configuration for opening and closing the front discharge port 211a disposed in the door assembly II.

The discharge port cover 25 opens the front discharge port 211a to expand the moving path of the pre-broadcast wind module 31. The pre-broadcast wind module 31 may protrude to the outside of the door assembly II through the open front discharge port 211a.

The discharge port cover 25 is located on the movement path of the pre-broadcast wind module 31. When the front discharge port 211a is opened, the discharge port cover 25 is moved out of the moving path of the pre-broadcast wind module 31.

The discharge port cover 25 is disposed in the front discharge port 211a, and is moved in the front and rear direction of the front discharge port 211a to open and close the front discharge port 211a, at least a part of the door cover 251 and the door cover 251 A door cover housing 253 that forms a space to be accommodated and adjusts the vertical position of the door cover 251, and is disposed between the door cover housing 253 and the door cover 251, and the door cover 251 is a door It includes a door cover moving module (not shown) that moves in the front-rear direction from the cover housing 253.

The door cover 251 is inserted into the front discharge port 211a and provides a surface continuous with the front portion 211 of the door panel 21. By the operation of the door cover moving module 252, the door cover 251 can be moved to the rear. After the door cover 251 is separated from the front discharge port 211a, the discharge port cover moving module 26 is operated to move the entire discharge port cover 25 downward.

When the door cover 251 is moved downward by the discharge port cover moving module 26, the front discharge port 211a is opened in the front-rear direction.

<Door Assembly-Discharge Port Cover Moving Module>

The discharge port cover moving modules 26a and 26b are configured to move the discharge port cover 25 in the vertical direction and set the front discharge port 211a disposed on the door panel 21 to an open state.

In this embodiment, the discharge port cover moving modules 26a and 26b are disposed on the left and right sides of the door cover housing 253, respectively. Unlike the present embodiment, only one discharge port cover moving module 26a, 26b may be disposed.

In this embodiment, since the discharge port cover moving modules 26a and 26b also function to fix the upper and lower positions of the discharge port cover 25, the discharge port cover moving module 26a, in order to distribute the supporting load of the discharge port cover 25, 26b) are placed on the left and right.

The discharge port cover moving modules 26a and 26b may move the discharge port cover 25 in the vertical direction along the door panel 21. In particular, the discharge port cover moving modules 26a and 26b may move the entire door cover housing 253 to which the door cover 251 is coupled in the vertical direction.

The discharge port cover 25 is moved along the insertion space 213 of the door panel 21. Since it is disposed inside the door panel 21, it is preferable that the installation space of the discharge port cover moving modules 26a and 26b be disposed below the insertion space 213.

In this embodiment, the discharge port cover moving modules 26a and 26b provide a structure to be installed to be less than the thickness of the door panel 21. In this embodiment, the thickness of the discharge port cover moving modules 26a and 26b in the front-rear direction is less than or equal to the thickness of the door panel 21.

The door cover 251 disposed on the movement path of the pre-broadcast wind module 31 facing the front discharge port 211a may be moved to the lower side of the front discharge port 211a by the operation of the discharge port cover moving modules 26a and 26b. .

When the door cover 251 is moved downward in the vertical direction, no part of the door cover 251 overlaps with the front discharge port 211a. The discharge port cover moving modules 26a and 26b move the door cover housing 253 out of the moving path of the pre-broadcast wind module 31.

The discharge port cover moving modules 26a and 26b include a first discharge port cover moving module 26a disposed on the left side of the door cover housing 253, and a second discharge port cover moving module disposed at the right side of the door cover housing 253. 26b).

The first outlet cover moving module 26a and the second outlet cover moving module 26b have the same configuration and are symmetrical left and right.

The motor shafts of the gear drive motors 262a and 262b are arranged in the vertical direction.

Since the discharge port cover moving modules 26a and 26b are moved in the vertical direction, the cables connected to the discharge port cover moving modules 26a and 26b are also inevitably moved in the vertical direction.

Since the thickness in the front and rear directions of the door assembly II is very small compared to the width, when the discharge port cover moving modules 26a and 26b are moved up and down, twisting of the cable may occur.

In addition, a cable is inserted between the discharge port cover moving modules 26a and 26b and the upper panel 23 moving up and down, so that the operation of the discharge port cover moving modules 26a and 26b may be restricted. A cable guide 27 may be disposed to minimize such a problem.

The upper end of the cable guide 27 is assembled to the discharge port cover 25, and the lower end of the cable guide 27 is assembled to the upper panel 23.
