The cam flow path 961 is not only used when the second cam 96 moves away from the first cam 95, but also when the second cam 96 moves toward the first cam 95. Even in this case, the moving speed of the second cam 96 can be limited. Therefore, the damper provided with the cam passage 961 is used not only when the door 2 closes the inlet 121, but also when the door 2 opens the inlet 121. 21) The rotation speed can be reduced.

A divider 94 may be further provided between the second cam 96 and the spring 93. The divider 94 is provided in a cylindrical shape that can reciprocate inside the chamber 912 and divides the space between the second cam 96 and the spring 93.

If the divider flow path 941 is provided with the above-described structure, when the second cam 96 moves in the direction in which it is separated from the first cam 95 (FIG. 6(b)), the divider flow path 941 The flow resistance becomes greater than the flow resistance when the second cam 96 moves in the direction in which it is coupled to the first cam 95 (FIG. 6(a)). Accordingly, the divider passage 941 of the above-described structure can provide a force of different magnitudes to the door body 21 depending on the rotation direction of the door body 21.

The second hinge 9 may further include a sealing portion. The sealing part may be provided with at least one of a first ring 97 fixed to the circumferential surface of the divider 94 and a second ring 98 fixed to the hinge cover 914.

The dampers 93, 94, 95, and 96 of the above-described structure are provided only at the second hinge 9. That is, the second hinge 9 is provided with a means for decelerating the door 2, but the first hinge 8 does not need to be provided with a means for decelerating the door. Since the laundry processing device 100 is provided with the damper only on one of the two hinges 8 and 9, not only can the rotational speed of the door 2 be limited, but also the manufacturing cost of the laundry processing device can be reduced. You can.

Hereinafter, with reference to FIG. 6, the second hinge 9 will be described when the door 2 opens or closes the inlet 121.

For convenience of explanation, Figure 6(a) defines a state in which the door 2 opens the inlet 121, and Figure 6(b) defines a state in which the door 2 closes the inlet 121. Defined as a state.

The second axis 92 of the second hinge 9 is fixed to the second support portion 99, and the first cam 95 rotates together with the housing 91. Since it is in a fixed state, when the door 2 rotates in the direction of closing the inlet 121, the first cam 95 rotates together with the door 2.

When the first cam 95 rotates together with the housing 91, the second cam 96 and the divider 94 rotate in the first cam 95, as shown in FIG. 6(b). Moves in a direction away from the second support (direction away from the second support, direction of compressing the spring).

When the second cam 96 and the divider 94 move in a direction away from the first cam, the liquid inside the spring 93 and the chamber 912 prevents the movement of the divider 94. Because it generates force, the second hinge 9 can minimize the collision between the door 2 and the cabinet 1.

Meanwhile, when the door 2 rotates in the direction of opening the inlet 121, the second cam 96 and the divider 94 will move toward the first cam 95. As shown in FIG. 6(a), in order for the second cam 96 and the divider 94 to move toward the first cam 95, between the first cam 95 and the second cam 96 The liquid flowing into the space must move in the direction where the spring 93 is located through the cam flow path 961 and the divider flow path 941. Since the liquid flowing into the space between the first cam 95 and the second cam 96 will limit the moving speed of the divider and the second cam, the second hinge 9 is used to control the door 2. ) can limit the rotational speed of the door 2 even when opening the inlet 121.

Since the structure and control method of the above-described clothing treatment device are described as an example of the present application, the scope of rights of the present application cannot be limited to the above-described structure and control method.
