[0032] The rotating tub 30 has a hollow cylindrical shape. A plurality of through holes 30b are provided in an outer circumferential surface of the rotating tub 30 to allow the water to pass. Lifters 30c are disposed on an inner circumferential surface of the rotating tub 30 while being spaced apart in a circumferential direction to lift laundry in the rotating tub 30 upward. Also, a rotation shaft 31 which receives a rotational force and allows the rotating tub 30 to rotate in the reservoir 20 is coupled to a rear surface of the rotating tub 30. The rotation shaft 31 is rotatably installed at a rear surface of the reservoir 20, and a rear end of the rotation shaft 31 passes through the rear surface of the reservoir 20 and protrudes from a rear side of the reservoir 20.

[0033] Also, the drum type washing machine includes a driving apparatus 60 which generates power to rotate the rotating tub 30.

[0034] The driving apparatus 60 includes a driving motor 61 which generates a rotational force, a driving pulley 62 installed at a rear end of a driving shaft 613 of the driving motor 61, which will be described below, and a driven pulley 63 which is installed at the rear end of the rotation shaft 31 and receives a rotational force from the driving pulley 62 through a belt 64.

[0035] The driving motor 61, as shown in FIGS. 2 and 3, includes a stator 611, a rotor 612 which is rotatably installed in the stator 611 and rotates while interacting with the stator 611, and the driving shaft 613 which is installed in a center of the rotor 612 and rotates together with the rotor 612. The driving pulley 62 described above is installed at the rear end of the driving shaft 613.

[0036] Also, the driving motor 61 includes cases 614F and 614S which form an exterior of the driving motor 61 and support the stator 611 and one pair of bearings 615 which are installed in each of the cases 614F and 614S and rotatably support both sides of the driving shaft 613.

[0037] The cases 614F and 614S include a first case 614F fixed to cover one side of the stator 611 and a second case 614S fixed to cover the other side of the stator 611. Bearing installation portions 614a which have hollow cylindrical shapes in which the bearings 615 described above are installed are provided in central portions of the first case 614F and the second case 614S. A shaft installation hole 614b which allows the rear end of the driving shaft 613 to pass through the second case 614S and to protrude from a rear side thereof is provided in a center of the second case 614S. Also, a bracket installation groove 614c concavely formed in an annular shape outside the bearing installation portion 614a, in which a fixing bracket 70 is installed, is provided in the first case 614F.

[0038] The driving motor 61 is installed on and fixed to an outer surface of the reservoir 20. To fix the driving motor 61 to the reservoir 20, the fixing bracket 70 is fixed to one side of the driving motor 61 and fixing portions 614d which integrally extend from the case 614S are provided at the other side of the driving motor 61.

[0039] The fixing bracket 70 is fixed to the first case 614F, and the fixing portions 614d are integrally extended from the second case 614S. Also, the first and second cases 614F and 614S are formed of a metal material and the fixing bracket 70 is formed of a resin material.

[0040] Accordingly, the emission of heat generated by the driving motor 61 is smoothly performed through the cases 614F and 614S formed of a metal. Since the driving motor 61 can be stored while being not coupled with the fixing bracket 70, it is easy to store the driving motor 61. Even though the fixing bracket 70 is fixed to the driving motor 61, since the fixing bracket 70 is formed of a relatively lightweight resin material rather than metal, the driving motor 61 may be simply installed.

[0041] The fixing bracket 70 includes a motor fixing portion 71 fixed to the first case 614F, a pair of reservoir fixing portions 72 fixed to an outer surface of the reservoir 20, a pair of first frame portions 73 which connect the pair of reservoir fixing portions 72 with the motor fixing portion 71, and a second frame portion 74 which connects the two reservoir fixing portions 72 with each other.

[0042] The motor fixing portion 71 includes a mounting hole 71a into which a bearing installation portion 614a provided in the first case 614F is mounted to allow an outer circumferential surface of the bearing installation portion 614a of the first case 614F to be supported by an inner circumferential surface of the mounting hole 71a. Also, the motor fixing portion 71 includes an extended rib 71b which is integrally extended from a portion adjacent to the mounting hole 71a in an annular shape and enters in the bracket installation groove 614c to support an outer surface of the bearing installation portion 614a and a plurality of reinforcing ribs 71c which extend from the extended rib 71b in a radial direction and are spaced apart in a circumferential direction. The extended ribs 71b forms the mounting hole 71a together with the motor fixing portion 71 to provide an effect of extending a length of the mounting hole 71a. Accordingly, the bearing installation portion 614a of the first case 614F may be stably mounted into and supported by the mounting hole 71a formed by the motor fixing portion 71 and the extended ribs 71b.

[0043] Also, a step portion 614e formed in an annular shape around the bearing installation portion 614a is provided at one surface of the first case 614F to which the motor fixing portion 71 of the fixing bracket 70 is fixed.

[0044] The two reservoir fixing portions 72 include fastening holes 72a to which fastening members are fastened, respectively. Also, although not shown in the drawings, buffering members for reducing the transfer of vibrations generated during an operation of the drum type washing machine may be installed at the fastening holes 72a in the two reservoir fixing portions 72, respectively.

[0045] The first frame portions 73, as shown in FIG. 4, are formed to have thicknesses which taper from the reservoir fixing portions 72 to the motor fixing portion 71. The second frame portion 74 is formed in a plate shape curved toward the motor fixing portion 71.

[0046] Also, the fixing bracket 70 includes supporting ribs 75, 76, and 77 which allow the components of the fixing bracket 70 described above to be mutually supported to increase the strength of the fixing bracket 70. The supporting ribs 75, 76, and 77 include a plurality of first supporting ribs 75 which are provided in an approximately triangular space formed between the first frame portions 73 and the second frame portion 74 and provide support in a space between the motor fixing portion 71 and the pair of reservoir fixing portions 72, a plurality of second supporting ribs 76 which provide support in a space between the motor fixing portion 71 and the second frame portion 74, and a plurality of third supporting ribs 77 which have an X shape and provide support in the space between the motor fixing portion 71 and the second frame portion 74. The third supporting ribs 77 comprise at least two portions which intersect to form an X shape.

[0047] Also, as shown in FIGS. 2 and 3, a plurality of temporary assembly protrusions 71d which protrude toward the first case 614F are provided at the motor fixing portion 71 and a plurality of temporary assembly holes 614f which are provided at positions corresponding to the plurality of temporary assembly protrusions 71d to allow the plurality of temporary assembly protrusions 71d to be respectively inserted thereinto are provided in the first case 614F.

[0048] Also, first fastening holes 71e and second fastening holes 614g are provided in the motor fixing portion 71 and the first case 614F in mutually corresponding positions, respectively, to allow the motor fixing portion 71 of the fixing bracket 70 to be fixed to the first case 614F using fastening members.

[0049] Accordingly, the fixing bracket 70 is temporarily assembled with the first case 614F by inserting the temporary assembly protrusions 71d into the temporary assembly holes 614f and then fastening members are fastened to the first fastening holes 713 and the second fastening holes 614g, thereby fixing the fixing bracket 70 to the first case 614F.

[0050] In the embodiment, the temporary assembly protrusions 71d and the first fastening holes 71e are alternately provided at the motor fixing portion 71 in a circumferential direction and the temporary assembly holes 614f and the second fastening holes 614g are alternately provided in the first case 614F in a circumferential direction.

[0051] In the embodiment, although one step portion 614e is shown as being provided, this is merely an example and not limited thereto. In another embodiment shown in FIG. 5, in a driving motor 61', a plurality of step portions 614e may be sequentially formed outside in a radial direction around the bearing installation portion 614a.

[0052] Also, in the embodiment, one side of the driving motor 61 is fixed to the reservoir 20 through the fixing bracket 70 coupled with the first case 614F and the other side thereof is coupled with the reservoir 20 through the fixing portions 614d integrally provided at the second case 614S but this is not limited thereto. As still another embodiment shown in FIG. 6, a first fixing bracket 70A is coupled with a first case 614F' of a driving motor 61" and a second fixing bracket 70B may be fixed to a second case 614S' to allow the driving motor 61" to be fixed to the reservoir 20 through the first fixing bracket 70A and the second fixing bracket 70B.

[0053] As is apparent from the above description, since a case of a driving motor is formed of a metal and a fixing bracket is formed of a resin material, the emission of heat generated by the driving motor can be easily performed, and since a weight of the driving motor is greatly reduced due to the fixing bracket formed of the resin material, it can be easily stored and installed.

[0054] Although a few embodiments of the present invention 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 invention as defined in the claims.
