When the door 7 further approaches the cabinet 10 side and the lever 70 presses the pressing portion 813 of the catcher 81, the catcher 81 rotates about the second shaft 842 in the counterclockwise direction A ). As the catcher 81 rotates about the second shaft 842, the first shaft 841 moves along the second guide hole 801b of the case 80 to be positioned in the first guide hole 801a . The interfering portion 814 of the catcher 81 may also be inserted into the locking hole 700 formed in the lever 70. As a result, the lever 70 can be interfered by the catcher 81 to be locked.

When the first shaft 841 is positioned in the first guide hole 801a, the frame 82 can slide rearward by the force that the lever 70 presses the pressing portion 813 of the catcher 81 . At this time, the speed at which the frame 82 slides rearward by the damper 84 can be controlled. That is, a force in a direction opposite to the direction in which the catcher 81 is pressed by the lever 70 is applied to the frame 82 by the damper 84, and the speed at which the frame 82 slides rearward is slowed down . The repulsive force that can be generated when the catcher 81 is rotated by the pressing of the lever 80 can be mitigated by the damper 84. [

The first shaft 841 is positioned in the first guide hole 801a so that the catcher 81 can not rotate around the second shaft 842. [ Therefore, the interference portion 814 can be kept inserted into the locking hole 700 of the lever 70. Thus, the lever 70 is interfered by the interference portion 814, so that the door 7 can be locked in a closed state, and the washing operation can be performed in a state in which the door 7 is locked.

After the washing operation is completed, the catcher 81 is operated in the reverse direction to that when it is locked, thereby releasing the locking state. When the lever 70 is pulled forward, the catcher 81 restraining the lever 70 also moves forward. At this time, the first shaft 841 can slide forward along the first guide hole 801a. When the first shaft 841 is moved to the front end of the first guide hole 801a connected to the second guide hole 801b, the catcher 81 is rotated in the clockwise direction B by the elastic force of the third elastic member 833, . When the catcher 81 rotates in the clockwise direction B, the interference portion 814 can escape from the locking hole 700 of the lever 70. The locking state of the door 7 can be released by canceling the interference state of the laker 70 by the interference portion 814. [ The user can open the door 7 with the locked state being released.

The locking device disclosed in Fig. 16 may include a guide 825 extending in the front-rear direction and a guide portion 847 rotatably provided with a rotation shaft on which the catcher 81 is mounted. The guide portion 847 may be provided at one end or the other end of the rotary shaft so as to be mounted on the rotary shaft and guided and moved by the guide 825. At least one side of the guide portion 847 guided by the guide 825 may have a semicircular cross section. The configuration of the elastic members 813, 814, the case 80 and the frame 82 may be similar to the locking device shown in Fig.

The maximum diameter d1 of the guide portion 847 is larger than the distance d2 between the guides 825 and the minimum diameter d3 of the guide portion 847 is smaller than the distance d2 between the guides 825 .

The longest diameter d1 side of the guide portion 847 is disposed on the guide 825 side so that the guide portion 847 can not enter the guide 825 and is interfered with in the state that the door 7 is opened . When the lever 70 presses the pressing portion 813 of the catcher 81 with the door 7 closed, the catcher 81 rotates about the rotating shaft and the guide portion 847 rotates together with the rotating shaft . The guide portion 847 rotates and a portion having a smaller diameter than the gap between the guides 825 is drawn into the guide 825 so that the guide portion 847 can move backward along the guide 825.

A damper 84 is provided at the rear of the frame 82 so as to transmit the damping force to the frame 82 moving backward together with the guide portion 847. The speed at which the lever 70 and the catcher 81 are moved backward by the damper can be decelerated. As a result, the repulsive force that can be generated when the catcher 81 rotates can be reduced, and the feeling of use of the user can be improved.

The locking device shown in Fig. 17 may include a sliding portion 817 including a pressing portion 817a and an interference portion 817b in the frame 82. [ When the lever 70 contacts the pressing portion 817a, the interference portion 817b moves and can be inserted into the locking hole 700 provided in the lever 70. [ The lever 70 presses the pressing portion 817a and the lever 70 and the sliding portion 817 can move backward together. At this time, the damper 84 may decelerate the speed at which the lever 70 and the sliding portion 817 move backward from the rear of the frame 82. The damper 84 is provided so that the sliding portion 817 is decelerated to move backward, thereby minimizing the repulsive force when the lever 70 and the pressing portion 817a come into contact with each other.

In the locking device shown in Fig. 18, a step portion 803b capable of selectively interfering with the catcher 81 may be formed in the case 80. Fig. The catcher 81 may be provided with a fixing portion 818 which can be interfered with by the stepped portion 803b. The fixing portion 818 may be provided with a portion of the catcher 81 so as to be selectively interrupted by the step portion 803b.

In a state in which the door 7 is opened, the fixing portion 818 may be interfered by the side wall 803a of the stepped portion 803b. The catcher 81 rotates in the counterclockwise direction when the door 7 is closed and the lever 70 presses the pressing portion 813 of the catcher 81. The fixing portion 818 is rotated by the side wall 803a The interference state can be released. The frame 82 on which the catcher 81 and the catcher 81 are mounted is released from the stepped portion 803b by the force exerted through the lever 70 when the state of interference by the side wall 803a is canceled by the fixing portion 818. [ As shown in Fig.

The speed at which the catcher (81) frame (82) slides rearward can be decelerated by the damper (84). This reduces the repulsive force that may be generated when the lever 70 presses the catcher 81 and smoothly locks the door 7, thereby improving the feeling of use when the door 7 is closed.

19, the locking device may include a catcher 81 provided with a gear portion 819 on the outer circumferential surface thereof, and a rack gear 880 engaged with the gear portion 819. The case 80 is provided with an interference portion 805 capable of selectively interfering with the rack gear 880. The interference portion 805 may be provided in the form of a hole or a groove into which the rack gear 880 can be selectively inserted.

The rack gear 880 can be maintained in an interfered state by the interfering portion 805 by the elastic member 836. [ When the lever 70 presses the pressing portion 813 of the catcher 81, the catcher 81 rotates and the rack gear 880 engaged with the gear portion 819 as the catcher 81 rotates, And can exit from the interfering unit 805. When the interference state of the rack gear 880 is released, the catcher 81, the rack gear 880, and the frame 82 can move backward by the pressing force applied to the lever 70. [

At this time, the damper 84 positioned at the rear of the frame 82 applies a damping force to the frame 82, and the catcher 81 and the rack gear 880 mounted on the frame 82 and the frame 82 move backward Can be decelerated. This can reduce the repulsive force that can be generated in the catcher 81 by the pressing force by the lever 70 and improve the feeling of use when the door 7 is closed.

Referring to Fig. 20, the locking device may include a sliding portion 882 having an inclined surface 882a. The sliding portion 832 can be selectively interfered with by the interference protrusion 883. [ For example, the interference protrusion 883 is located at the lower portion of the sliding portion 832 and can receive the elastic force from the elastic member 838 to maintain the raised state. The interference protrusion 883 can be inserted into the interference hole 882b provided in the sliding portion 882 in the raised state to interfere with the sliding portion 832. [

At least a portion of the lever 70 may be pivotably mounted about a rotational axis 702. [ The portion pivotable by the rotating shaft 702 can be referred to as a latch portion 701. [ The rotation shaft 702 is provided with an elastic member (not shown), so that the end portion of the lever 701 can be pressed downward by the elastic force. The latch portion 701 may include a bent portion. The bent portion of the latch portion 701 may be arranged to face downward.

When the latch portion 701 is pulled into the locking device, the end portion of the latch portion 701 can move along the inclined surface 882a of the sliding portion 882. [ The latch portion 701) can be inserted into the interference hole 882b through the inclined surface 882a to press the interference protrusion 883. When the interference protrusion 883 is pressed, the interference state of the sliding portion 832 by the pressing protrusion 883 is released and the sliding portion 882 is moved backward together with the lever 70 by the force applied to the lever 70 . ≪ / RTI >

At this time, the speed at which the lever 70 and the sliding portion 882 move can be reduced by the damper 84 positioned at the rear. As described above, the speed at which the lever 70 and the sliding portion 882 move backward is reduced, thereby improving the feeling of use when the user closes the door 7. [

Referring to Fig. 21, the catcher 81 included in the locking device can be selectively interfered by the support portion 884. Elastic members 831 and 832 may be provided in front of the frame 82 on which the catcher 81 is mounted. The elastic members 831 and 832 can transmit an elastic force to the frame 82 in a direction to push the frame 82 backward.

The support 884 may be pivotable about a rotation axis 884a. The catcher 81 may be rotatably provided by a rotating shaft 848. [ The support shaft 884 interferes with the rotation axis 848 of the catcher 81 so that the frame 82 on which the catcher 81 and the catcher 81 are mounted can not be pushed rearward.

The case 80 may be provided with a first guide 827 for guiding the rotation shaft 848 to move in the forward and backward directions. The support portion 884 can be positioned behind the rotary shaft 848 such that the rotary shaft 848 is positioned in front of the first guide 827 in a state that the door 7 is opened.

The case 80 may be provided with a second guide 826 which is bent downward at a front part thereof. The frame 82 may be provided with an elastic member 839 supported by the second guide 826. The elastic member 839 can be supported by the second guide 826 through the support portion 827. [ The elastic member 839 can be positioned such that one side of the pressing portion 813 is positioned forward so that the pressing portion 813 of the catcher 81 can be pressed by the lever 70. [

When a force larger than the elastic force of the elastic member 839 is applied to the pressing portion 813 through the lever 70, the catcher 81 rotates counterclockwise and the supporting portion 827 rotates the second guide 826 Can move along. The catcher 81 can move backward along the second guide 826 when the support portion 827 moves along the bent surface and reaches a straight line extending in the front-rear direction. The support 884 can be pivoted about a rotation axis 884a as the catcher 81 moves backwardly. The damper 84 provides a damping force to the frame 82 on which the catcher 81 is mounted, It is possible to decelerate the speed at which the motor 81 moves rearward. Also, the repulsive force that can be generated when the catcher 81 is pressed by the lever 70 can be reduced.

The catcher 81 and the sliding portion 817 for locking the door 7 by interfering with the lever 70 provided on the door 7 can be referred to as a locking portion. When the lever 70 is in contact with the locking part, the lever 70 and the locking part are slid rearward, and the speed at which the lever 70 is slid rearward is reduced by the damper provided at the rear of the locking part, So that the door 7 can be smoothly closed so that the feeling of use of the user can be improved. Examples of the locking device to which the damper can be applied are not limited to those described above.
