When viewed from a front side of the body 20, the hinge assembly 30 is installed at the hinge installation part 20a positioned to the left of the laundry handling apparatus and the installation cover 40 is installed at the hinge installation part 20a positioned to the right of the laundry handling apparatus, so that the inlet 11a is open as the door 20 rotates from a right side to a left side thereof.
The hinge assembly 30, as illustrated on FIG. 2, includes a hinge member 31 installed at a front surface of the body 10, and hinge brackets 32 and 33 that installed to the door 20 to have the hinge member 31 rotatably coupled thereto so that the door 20 may be rotatably installed at the body 10.
The hinge member 31 includes a fixation part 31a formed in a shape of a panel and fixedly installed to the body 10 through a screw S, a hinge shaft 31b having a circular cross section and rotatably installed at the hinge brackets 32 and 33, and a connecting part 31c connecting the fixation part 31a to the hinge shaft 31b. The hinge shaft 31b according to the embodiment of the present disclosure is provided with two units thereof at an upper portion and a lower portion of the door 20, respectively, to reduce the door 20 being deflected.
The hinge brackets 32 and 33 include a first hinge bracket 32 and a second hinge bracket 33 coupled to each other so that the hinge shaft 31b may be rotatably installed between the first hinge bracket 32 and the second hinge bracket 33. The second hinge bracket 33 according to the embodiment of the present disclosure includes a hinge groove 33a at which the hinge shaft 31b is rotatably accommodated. The first hinge bracket 32 is installed to cover the hinge installation part 20a, and includes a hinge supporting part 32a for the hinge shaft 31b to maintain a state of an installation at the hinge groove 33a. Since two units of hinge shafts 31b are provided at the hinge member 31 according to the embodiment of the present disclosure, the second hinge bracket 33 is provided with two units thereof and the two hinge brackets 33 are coupled to an upper portion and a lower portion of the first hinge bracket 32, respectively.
The installation cover 40 includes a latch 41 allowing the door 20 to maintain a closed state of the inlet 11a while interacting with a locking apparatus (not shown) installed at the body 10.
In addition, as illustrated on FIGS. 5 to 6, in order to install the hinge brackets 32 and 33 to the body 10, a fixation bracket 12 is disposed to a rear surface of a front panel 11, which forms a front surface of the body 10, for the hinge member 31 to be fixedly installed at the front surface of the body 10.
The fixation part 31a of the hinge member 31 is provided with a first fastening hole 31d for the hinge member 31 to be fixedly coupled to the fixation bracket 12 through the screw S, and the fixation bracket 12 is provided with a second fastening hole 12a at a position corresponding to the first fastening hole 31d. Accordingly the hinge member 31 may be fixedly installed at the fixation bracket 12 by fastening the screw S at the first fastening hole 31d and the second fastening hole 12a. Each of the first fastening hole 31d and the second fastening hole 12a of the embodiment of the present disclosure is provided in plurality at an upper portion and a lower portion at positions, each first fastening hole 31d corresponding to each second fastening hole 12a so that the hinge member 31 may be prevented from being rotated by the gravity of the door 20. In addition, the front surface panel 11 is provided with a third fastening hole 11b at a position corresponding to the first fastening hole 31d and the second fastening hole 12a so that the screw S may be penetrated and installed to the first fastening hole 31d and the second fastening hole 12a. 
When installing the hinge assembly 30 or the hinge member 31 being coupled to the door 20, the hinge member 31 may be rotated by the gravity of the door 20 in a state that the screw S is coupled to one of the first fastening hole 31d and one of the second fastening hole 12a. In this case, in order to fasten the screw S to the remaining one of first fastening holes 31d and the remaining one of the second fastening holes 12a, the door 20 needs to be held in a way to prevent the hinge member 31 from being rotated when the screw S is needed to be fastened to the remaining one of first fastening holes 31d and the remaining one of the second fastening holes 12a. 
Thus, the fixation part 31a of the hinge member 31 is provided with a supporting part 31e protruded from a rear surface thereof and supported by the fixation bracket 12, and the fixation bracket 12 is provided with a supporting hole 12b into which the supporting part 31e is inserted and supported. The front surface panel 11 is provided with a penetrating hole 11c thereto so that the supporting part 31e may penetrate through the penetrating hole 11c and be inserted into the supporting hole 12b. The supporting part 31e according to the embodiment of the present disclosure is provided in between the two units of the first fastening holes 31d that are vertically disposed. That is, the first fastening hole 31d is provided each at an upper side and a lower side of the supporting part 31e. 
In addition, the supporting part 31e is provided with both side surfaces thereof each formed in a shape of a plane surface that is parallel to each other, and the supporting groove 12b is provided with both side ends thereof each formed in a linear shape that is parallel to each other so that the both side ends may correspond to the supporting part 31e. Thus, as the both side surfaces of the supporting part 31e are either line-contacted or surface-contacted with the both side ends of the supporting hole 12b, the supporting part 31e is supported by the both side ends of the supporting hole 12b in a further stable manner, and thus the rotation of the hinge member 31 is prevented.
With respect to the laundry handling apparatus structured as such, the following is a description of an installation process of a door in a state of an opening/closing direction thereof changed.
First, as illustrated on FIG. 1, in a state when a right end side of the door 20 is installed on a right side of the body through the hinge assembly 30, the hinge assembly 30, that is, the hinge member 31, is separated from the front surface panel 11 of the body 10, so that the door 20 is separated along with the hinge assembly 30. Then, the hinge assembly 30 and the installation part cover 40 are separated from the two units of the hinge installation part 20a provided at the rear surface of the door 20. Sequentially, each of the hinge assembly 30 and the installation part cover 40 is installed at the hinge installation part 20a that is positioned at an opposite side of the position at which the hinge assembly 30 and the installation part cover 40 are originally installed. That is, while having the drawing of FIG. 3 as a reference, the hinge assembly 30 installed at a left side of the rear surface of the door 20 and the installation part cover 40 installed at a right side of the rear surface of the door 20 are installed at opposite positions, as illustrated on FIG. 4.
As described above, in a state of the hinge assembly 30 installed to the door 20 while having the hinge assembly 30 and the installation part cover 40 reversely changed in the position the hinge assembly 30 is fixed again to the front surface panel 11 of the body 10. The fixation of the hinge assembly 30 is taken place by fastening the hinge member 31 to the fixation bracket 12 that is disposed at a rear surface of the front surface panel 11 of the body 10 by use of the screw S.
First, the hinge member 31 is disposed such that the supporting part 31e of the hinge member 31 is installed by passing through the supporting groove 12b, one among the plurality of the first fastening holes 31d and one among the plurality of the second fastening holes 12a both of which correspond to each other are fastened with the screw S. At this time, even in a case when only one screw S is fastened at the first fastening hole 31d and the second fastening hole 12a, the hinge member 31 is in a state of being supported by the both side ends of the supporting hole 12b of the fixation bracket 12 through the both side surfaces of the supporting part 31e, and thus the hinge member 31 maintains a constant position without being rotated. Thus, the remaining one of the first fastening holes 31d and the remaining one of the second fastening holes 12a may maintain a corresponding position to each other, thereby enabling an operator to easily fasten a screw.
The door 20 according to the embodiment of the present disclosure is formed in a rectangular shape while being provided with an upper portion thereof and a lower portion thereof in an asymmetrical manner, but the present disclosure is not limited hereto, and the present disclosure may be applied to various shapes of doors each provided with an upper portion thereof and a lower portion thereof in an asymmetrical manner.
The first fastening hole according to the embodiment of the present disclosure is provided at both an upper side and a lower side of the supporting part, but is not limited thereto, and the first fastening hole may be formed at one side thereof.
Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
