Here, the inner frame 43 is configured to be coupled to the outer frame 41 with the pressing piece 990 interposed therebetween. That is, the pressing piece 990 is disposed between the inner frame 43 and the outer frame 41.

In addition, the inclined surface 1005 of the protrusion 1004 may be formed to be inclined toward the pressing portion 994. For example, the inclined surface 1003 may be formed to be inclined in a direction toward the first hinge 5 of the door 4 (ie, toward the left as viewed in FIG. 6 ). That is, the protrusion 1004 protruding from the first switching unit 1000 in the direction of the inner frame 43 may be formed to gradually increase in width toward the inner frame 43. Accordingly, the inclined surface 1005 may be formed on the side surface of the protrusion 1004 facing the pressing part 994. In this case, the inclined surface 1005 of the protrusion 1004 may be disposed so that at least a portion of the pressing portion 994 is in contact with each other.

Therefore, when the user grips the hand on the pressing piece 990 and presses the first portion 996 of the pressing piece 990 (that is, the pressure point 998 of the first portion 96), the pressing piece ( 990 rotates counterclockwise around the pivot shaft 995. That is, when the first portion 996 of the pressing piece 990 is pressed, the second portion 997 moves in a direction opposite to the direction in which the first portion 96 is pressed. In other words, when the pressure point 998 of the pressing piece 990 is pressed by the user, the first portion 996 of the pressing piece 990 moves in the direction in which it is pressed, and the second portion 997 of the pressing piece 990 ) Provided in the pressing part 994 moves in a direction opposite to the direction in which the first part 996 is pressed. Specifically, when the pressure point 998 of the pressing piece 990 is pressed by the user, the first portion 996 moves toward the outer frame 41, and the pressing portion 994 provided in the second portion 997 ) Moves toward the inner frame 43 (see arrow in FIG. 7). At this time, the pressing portion 994 of the second portion 997 pushes the protruding portion 1004 of the first switching portion 1000 so that the first switching portion 1000 moves in the horizontal direction of the door 4 (that is, It is moved in the width direction or lateral direction of the door). For example, when the pressing part 991 pushes the inclined surface 1005 of the protrusion 1004 provided in the first switching unit 1000 toward the inner frame 43, the first switching unit 1000 is ( 6) can be moved in the right direction.

In addition, a plurality of ribs 999 spaced apart at predetermined intervals and extending in a vertical direction in the first portion 996 of the pressing piece 990 so that the user's fingers can be easily gripped by the pressing piece 990 Can be formed. The user may press the pressing piece 990 by holding a finger between the plurality of ribs 999. In addition, the configuration of the ribs 999 may be equally applied to the embodiment of the pressing piece 990 described with reference to FIG. 7.

Meanwhile, in the outer frame 41 and the pressing piece 990 shown in FIGS. 7 and 8, the outer frame 41 may be bent in a direction in which the pressing piece 990 is pressed. Specifically, when the pressure point 998 of the pressing piece 990 is pressed by a user, the bent portion of the outer frame 41 disposed in the direction in which the first portion 996 of the pressing piece 990 is pressed 401 may be bent in a direction in which the first portion 996 is pressed. Accordingly, the angle at which the pressing piece 990 is pivoted may increase as the bent portion 41 of the outer frame 41 is bent. Of course, the bent portion 401 of the outer frame 41 is formed only in the portion corresponding to the first portion 996 of the pressing piece 990, or is formed over the entire length direction of the upper side of the outer frame 41 Can be.

In addition, in the embodiment shown in FIGS. 7 and 8, the first switching unit 1000 of the rotating shaft switching unit is disposed between the outer frame 41 and the second portion 997 of the pressing piece.

9 is a view showing the relationship between the movement of the first switching unit and the first hinge according to the operation of the pressing piece, Figures 10 and 11 are views showing the relationship between the movement of the second switching unit and the third hinge according to the operation of the pressing piece, 12 is a view showing a relationship between a second switching unit and a third hinge when the door is rotated in a second rotation direction.

Hereinafter, with reference to FIGS. 9 to 12, the rotation direction of the first switching unit 1000, the second switching unit 1100, and the door 4 according to the pressing of the pressing piece 990 will be described in detail. .

When the pressure point 998 of the pressing piece 990 is pressed by the user, and the first switching unit 1000 moves in the lateral direction (right direction), the first receiving groove 531 in which the first shaft 51 is accommodated Is open. Accordingly, the first shaft 51 may be removed from the first receiving groove 531 (see FIG. 9 ).

On the other hand, as shown in FIG. 9, when the first switching unit 1000 is closing the first receiving groove 531, the first shaft 51 can escape from the first receiving groove 531. Since there is no, the door 4 is rotatably coupled about the first axis 51 with respect to the cabinet 3.

However, when the first switching unit 1000 is moved to the right by the above-described operation, the first shaft 51 accommodated in the first receiving groove 531 comes out of the first receiving groove 531, As a result, it is not coupled to the door 4 and the cabinet 3 through the first hinge 5 which is the first shaft 51.

That is, when the user wants to rotate the door 4 in the first rotation direction, the door 4 must rotate around the first axis 51 which is a part of the first rotation axis. Therefore, the door 4 and the first shaft 51 must be kept fixed.

Therefore, in this case, the user grips the side handle 980 formed on the side of the door 4 and rotates the door 4 around the first rotation axis A, or presses the recessed portion 992. The door 4 may be rotated around the first rotation axis A by holding a portion other than the piece 990 (for example, a portion far from the first rotation axis A in the depression 992 ). At this time, since the pressing piece 990 is not pressurized, the first switching unit 1000 remains in a stopped state, and the first switching unit 1000 seals the first receiving groove 531 Maintain the state. Therefore, the first shaft 51 is not removed from the first receiving groove 531, and forms the first rotation shaft so that the door 4 can be rotated in the first rotation direction.

10 to 12 show the coupling structure of the third hinge 7 portion. The third hinge 7 includes a fourth shaft 713 forming the second rotation shaft, and a fourth shaft attachment/detachment part 73 having a second receiving groove 731 detachable from the fourth shaft 713 Includes. The fourth shaft 713 is provided in the door 4, the fourth shaft attaching and detaching part 73 is provided at the cabinet 3, and the fourth shaft 713 is the fourth shaft attaching and detaching part (73) can be attached or detached.

In FIG. 10, since the door 4 is in a state in which the inlet 37 is closed, the fourth shaft 713 is completely inserted into the second receiving groove 731. At this time, when the user rotates the door 4 along the first rotation direction, the fourth shaft 713 is the second receiving groove 731 in the horizontal direction (that is, in the direction of the arrow shown in FIG. 10). ) Can be withdrawn. That is, since the second switching unit 1100 does not seal the horizontal entrance of the second receiving groove 731, the fourth axis 713 is not interfered with the second switching unit 1100 , It may be moved in a horizontal direction from the second receiving groove 731.

The cross section of the fourth shaft 713 may have a first flat surface 714 having a flat side. At this time, the fourth shaft 713 may have a'D' shape as a whole and may have the first flat surface 714 on the upper side. Meanwhile, the fourth shaft attachment/detachment part 73 is provided with a stopper 74 that restricts rotation of the fourth shaft 713 by a predetermined angle or more. The stopper 74 may include a second flat surface 741 corresponding to the first flat surface 714. Therefore, when the fourth shaft 713 rotates by a predetermined angle, the first flat surface 714 and the second flat surface 741 come into surface contact with each other, so that the rotation of the fourth shaft 713 stops. Can be.

FIG. 11 shows a state in which the second switching unit 1100 in FIG. 10 is moved downward. When the user desires to rotate the door 4 in the second rotation direction, the user presses the pressing piece 990, that is, the pressure point 998 of the pressing piece 990. As shown in Figs. 6 to 8, when the pressing piece 990 is pressed, the first switching unit 1000 is moved to the right. Then, the second switching unit 1100 moves downward. That is, as illustrated in FIG. 11, the second switching unit 1100 is moved downward than the position illustrated in FIG. 10. Accordingly, the second switching unit 1100 may seal the second receiving groove 731 and prevent the fourth shaft 713 from being drawn out from the second receiving groove 731 in the horizontal direction.

In this case, a guide groove 732 in which the free end of the second switching unit 1100 is rotatable may be formed in a portion corresponding to the free end of the second switching unit 1100 in the cabinet 3. . For example, the fourth shaft attachment/detachment part 73 installed in the cabinet 3 may include the guide groove 732.

When the fourth shaft 713 is drawn out in the horizontal direction, it means that the door 4 is rotated in the first rotation direction described above. Therefore, when the pressing piece 990 is pressed and the second switching unit 110 seals the second receiving groove 731 of the fourth shaft attaching/detaching part 73, the door 4 is moved in the second rotation direction. During rotation, the door 4 is prevented from simultaneously rotating in the first rotation direction. That is, the door can be prevented from being removed from the cabinet at the same time in the first hinge 5 and the third hinge 7.

On the other hand, when the pressing piece 990 is operated (that is, when it is pressed), the first switching unit 1000 is also moved to the right, and the first shaft 51 is removed from the first receiving groove 531 Thus, the door 4 and the cabinet 3 are separated from the first hinge 5. Therefore, the door 4 can be rotated in the second rotation direction.

On the contrary, when the user tries to rotate the door 4 in the first rotation direction, the pressing piece 990 is not pressed by the user. Accordingly, the first switching unit 1000 and the second switching unit 1100 do not operate and maintain their original state. That is, since the second switching unit 1100 does not descend and is disposed at the position shown in FIG. 10, the fourth shaft 713 can be removed from the second receiving groove 731. Therefore, the door 4 can be rotated in the first rotation direction.

12 shows a state in which the door 4 is rotated in the second rotation direction. As shown in Fig. 12, when the door 4 is rotated in the second rotation direction, the fourth shaft 713 and the second switching unit 1100, which are components installed in the door 4, It is also rotated at the same angle along the door 4.

When the door 4 rotates by a predetermined angle and the first flat surface 714 of the fourth shaft 713 comes into contact with the second flat surface 741 of the stopper 74, the fourth shaft The rotation of 713 is stopped. At this time, the rotation angle in the second rotation direction of the door 4 may be approximately 30 degrees to 40 degrees. This angle can be changed according to the user's convenience.

Meanwhile, in the laundry treatment apparatus having only the above-described structure, when the user presses the pressure point 998 of the pressing piece 990 when the door 4 rotates with respect to the first rotation axis A, the first axis 51 There is a disadvantage in that it can be separated from the first receiving groove 531 of the one-axis detachable part 53.

In addition, when the door 4 rotates by the second rotation shaft B, the laundry treatment apparatus having only the above-described structure must keep the pressure point 998 of the pressing piece 990 pressed until the fourth axis ( There is a disadvantage in that 713 can be prevented from being separated from the second receiving groove 731 of the fourth shaft attachment/detachment part 73.

Therefore, in order to solve the above-described disadvantages, the laundry treatment apparatus according to the present invention has the first switching unit 1000 when the door 4 opens the inlet 37 (that is, when the door is separated from the front panel 33). ) Or a lock 70 for fixing the position of the second switching unit 1100 (ie, restraining the first switching unit or the second switching unit) may be further included.
