That is, as will be described later, as another embodiment 140, the support unit 140 is configured such that one end of the support body 141 is hinged to the hinge coupling part 142 in the insertion hole 146 , And the other end is installed to be movable toward a room immediately after the front door (30) while being rotated about the hinge engaging part (142).

5, the other end of the supporting body 141 according to another embodiment is inclined toward the main body 10 when an external force is not applied.

The other end of the support body 141 protrudes obliquely toward the main body 10 because the other end of the main body 10 and the support body 141 are in contact with each other to form the ventilation gap 50 When the user further applies an external force to the front door 30 and the hook portion 60 is locked to the door latch assembly 70 by the user, So as not to be switched.

The other end portion 47a of the front door 30 is not in close contact with the main body 10 while the other end portion of the support body 141 is in contact with the main body 10. [ And the support body 141 is rotated to be restored to the insertion hole 146 when an external force is applied to the front door 30 by a user.

The supporting body 141 is supported by the hinge engaging part 142 so that the one end 143a is supported by the insertion hole 146 and the other end 143b is supported by the supporting body 141 And is elastically supported by a second supporting elastic member 143 for supporting the end portion in a rotating direction about the hinge engaging portion 142.

Here, the second supporting elastic member 143 may be a torsion spring interposed in the hinge engaging part 142.

The second support elastic member 143 of the torsion spring has one end portion 143a supported by the first support portion 147a formed in the insertion hole 146 and the other end portion 143b of the second support elastic member 143 supported by the support And is supported by a second support portion 147b formed on the body 141. [

The supporting unit 140 of the drum washing machine 1 according to another embodiment has the same structure as that of the preferred embodiment 40 and the other embodiment 140 described above except that the supporting body 141 is contacted The main body 10 may be made of a metal material and the support body 141 may further include a magnet 145 for magnetically coupling the support body 141 and the main body 10.

The support body 141 may be provided at its distal end with a noise prevention part 148 for preventing noise from being generated when the support body 141 and the main body 10 are in contact with each other. The noise preventing part 148 may also be coupled to the distal end of the supporting body 141 between the supporting body 141 and the main body 10.

The support unit 40 including the support bodies 41 manufactured by the various embodiments 40 and 140 may be spaced apart from the inner end of the front door 30 .

6A to 6C, the supporting unit 40 includes a plurality of ridges 33 of the front door 30, and a plurality of ridges 33 of the rim 34. In the drum washing machine according to the preferred embodiment of the present invention, A plurality of the inner frames 32 may be arranged in the inner frame 32 as well as a plurality of the inner frames 32 may be arranged.

6A, the support unit 40 includes a vertical line C1 passing through the center C of the transmissive portion 35, and a vertical line C1 passing through the center C of the transmissive portion 35. As shown in FIG. 6A, Two of the frame parts 33 corresponding to upper and lower parts of the inner frame 32 may be vertically spaced apart from each other.

6B, the support unit 40 is installed on the front surface of the front door 30 along the vertical line C1 passing through the center of the transmission portion 35, A plurality of ridges may be provided at any one of upper and lower portions of the inner frame 32 among the rim portions 33 corresponding to an arbitrary vertical line C2 between the other ends 30a of the inner frame 32. [

6 (c), the supporting unit 40 is disposed on the inner frame 30 of the frame part 33 corresponding to the arbitrary vertical line C2, (Not shown).

Here, it is preferable that the arbitrary vertical line C2 is disposed adjacent to the other end 30a of the front door 30.

As described above, the elements for determining the installation position and the installation number of the support unit 40, as in the first to third embodiments, The elastic force of the elastic member 39 and the elastic force of the first supporting elastic member 44 (or the second supporting elastic member 143) supporting the supporting body 41 and the magnetic force of the magnet 45.

That is, the force generated by the elastic force of the door elastic member 39 in the direction in which the front door 30 closes the entrance portion 23 is generated by the elastic force of the first supporting elastic member 44 When the front door 30 is larger than the force for pushing the front door 30 forward from the main body 10, the front door 30 is switched from the unlocked state to the locked state, There is a problem that the ventilation function can not be secured.

A force for pushing the front door 30 forward from the main body 10 generated by the elastic force of the first supporting elastic member 44 is transmitted to the door elastic member 39 by the elastic force of the door elastic member 39, If the force of the front door 30 is greater than the force of closing the door 23, the ventilating function of the support unit 40 can be ensured. However, due to the magnetic force of the magnet 45 When a force for pushing the front door 30 forward due to the elastic force of the door elastic member 39 is greater than the adhesive force, a predetermined distance between the front door 30 and the main body 10 The original purpose of maintaining the ventilation gap 50 can not be achieved. The reason why the ventilation gap 50 is maintained is to avoid the interference with the surrounding objects of the front door 30.

The elastic force of the first supporting elastic member 44 and the magnetic force of the magnet 45 should be at least greater than the elastic force of the door elastic member 39. [

It is needless to say that when the support unit 40 is provided at two positions on the rear surface of the front door 30, the magnetic force of the magnet 45 doubles.

The door elastic member 39 and the first supporting elastic member 44 (see FIG. 4) are disposed at positions corresponding to the positions of the first supporting elastic member 44 and the magnet 45 in the rear portion of the front door 30, And the magnetic force of the magnet 45 are determined.

6A, when the support unit 40 is positioned on the vertical line C1 passing through the center C of the transmission portion 35 among the rear portions of the front door 30, The member 39 and the support unit 40 are positioned close to each other, and the magnet 45 must have a relatively large magnetic force. Therefore, it is preferable that two portions are provided at the upper and lower portions of the vertical line C1.

6B, the support unit 40 is positioned between the center C of the transmission portion 35 and the other end portion 30a of the front door 30 among the rear portion of the front door 30 The door elastic member 39 and the supporting unit 40 are located relatively far away from each other when the door 45 is positioned on the arbitrary vertical line C2. . The support unit 40 may be provided on any one of the upper and lower sides on the arbitrary vertical line C2.

However, it is not necessary to limit the support unit 40 to any one of the upper and lower sides of the arbitrary vertical line C2 as shown in FIG. 6B, and in some embodiments, as shown in FIG. 6C And may be disposed on both upper and lower sides of the arbitrary vertical line C2.

The operation of the preferred embodiment of the drum washing machine 1 according to the present invention as described above is performed when the door 23 is closed by the front door 30 and when the door 23 is closed by the front door 30, Will be described in detail with reference to the accompanying drawings.

4A, when the user pushes the front door 30 to close the door 23 when the door 23 is closed by the front door 30, The other end portion 30a is moved toward the entry / exit portion 23 while being rotated around the one end portion 30b of the front door 30. At this time, the support body 41 is protruded toward the entrance portion 23 by the first support elastic member 44, and when the front door 30 is continuously moved, The front end portion is brought into contact with one side of the entry / exit portion 23.

If the user does not apply an external force any more, the magnet 45 disposed at the distal end of the supporting body 41 contacts the main body 10, The front door 30 is magnetically coupled to the main body 10 while forming / maintaining the ventilation gap 50, which is a separation distance of the front door 30. At this time, the front door 30 is urged forward by the elastic force of the door elastic member 39 interposed in the hinge engagement portion D, which is one end 30b of the front door 30, Is smaller than the force due to the adhesive force of the magnet 45, the front door 30 continuously maintains the ventilation gap 50 when the drum washing machine 1 is not used.

4A, when the user presses the button operation portion (not shown) disposed on the front surface 20 of the main body 10 to input laundry into the internal space 2 through the access portion 23, The actuator 80 is activated and the wire 76 is pulled upward so that the operating rod 74 and the moving rod 75 and the stopper portion 73 are interlocked together And rotates the engaging part 72.
