The operation part 130 of the drain selector 104 may be provided in a triangular shape. That is, the operation unit 130 may include a first point 131, a second point 132, and a third point 133. On one side of the operation part 130, a connection part 134 for connecting the drain connection member 137 is located. The other part of the operation part 130 prevents the operation part 130 of the drain selector 104 from rotating excessively and the drain selector 138 is opened to maintain the drain valve 138 open or closed. (Not shown). According to an embodiment of the present invention, the connection portion 134 may be positioned between the first point 131 and the third point 133, and the support portion 135 may include the second point 132 and the third point 133 ). ≪ / RTI >

The supporting portion 135 is provided such that one side surface thereof is supported by the drainage elastic member 136 located below the operation portion 130. Accordingly, the support portion 135 may be provided in a flat shape so as to be in contact with the drainage elastic member 136. According to an embodiment of the present invention, the drainage elastic member 136 may be provided with a leaf spring. The drainage elastic member 136 supports and fixes the support portion 135 of the operation portion 130 when the operation portion 130 rotates.

The drainage elastic member 136 is fixed by the fixing portion 114 on the rear surface of the control panel 111. [ The operating portion 130 does not rotate at an angle greater than a predetermined value when the operating portion 130 is in the drain mode and in the washing mode and contacts the engaging portions 112 and 113 on the rear surface of the control panel 111. [ That is, as in the embodiment of the present invention, when the actuating part 130 has a triangular shape, two locking parts 112 and 113 may be provided. That is, in the case of the washing mode in which the drain port 139 is opened when it contacts the first latching part 112, In the case where the operating portion 130 rotates and contacts the second engaging portion 113, the drain port 139 is closed.

16 is a view showing a drain selector according to an embodiment of the present invention.

As shown in FIG. 16, the operation unit 130 of the drain selector 104 according to an embodiment of the present invention rotates to determine a washing mode or a drain mode. When the connection portion 134 and the support portion 135 are located at a, the mode corresponds to the washing mode. When the connection portion 134 and the supporting portion 135 are located at the b, the mode corresponds to the drain mode. In order to switch from the laundry mode to the drain mode, or vice versa, the operation part 130 rotates 120.. The drain connection member 137 moves by the displacement difference S1 corresponding to the rotation of the operation part 130. [

Conventionally, the actuating part is provided in a quadrangular shape, so that the actuating part rotates by 90 [deg.] And the drain connecting member moves by the displacement difference corresponding thereto. However, according to the embodiment of the present invention, the actuating part 130 is provided in a triangular shape, so that the actuating part rotates by 120 °, and the displacement of the actuating part 130 moves accordingly. Since the difference in displacement is reduced, the torque is reduced. Accordingly, the user can rotate the drain selector 104 to rotate the operating part 130 with less force than the conventional one, unlike the conventional technique.

Also, according to an embodiment of the present invention, if a round is given to the first point 131, the second point 132, and the third point 133 of the actuating part 130, R may be 8. In this case, since the first point 131, the second point 132, and the third point 133, which are the corners of the actuating part 130, are provided in a rounded shape so as not to be tilted, It requires less force to rotate than when corner is angled and thus may increase usability.

The lever switch 140 may be coupled to the upper panel 180 located below the upper cover 100. Since the upper panel 180 is coupled to the door 101, the lever switch 140 coupled to the upper panel 180 may be turned on or off according to the movement of the door 101. That is, when the door 101 is opened, since the first connection unit 151 and the second connection unit 161 are separated from each other, the lever switch 140 is turned off. When the door 101 is closed, since the first connection unit 151 and the second connection unit 161 are in contact with each other, the lever switch 140 is in a turned-on state.

Since the dewatering motor 43 determines whether the brake 170 is driven or not, depending on whether the lever switch 140 is connected or not, the dewatering motor 43 is driven to the brake 170, As shown in FIG. This is because when the driving of the dewatering motor 43 is stopped electrically, the dewatering motor 43 is not immediately stopped by the rotational force, so that the dewatering motor 43 is physically moved instantaneously through the frictional force generated in the brake 170 .

 When the lever switch 140 is not connected, the door 101 is opened, and the first connection unit 151 and the second connection unit 161 are spaced apart from each other. As a result, the power is not connected to the dehydrating motor 43, and the brake 170 is operated to stop the dehydrating motor 43 from being driven.

The first connection terminal 152 of the first connection unit 151 and the second connection terminal 162 of the second connection unit 161 are spaced apart from each other as shown in Fig. do. Even when the first connection terminal 152 and the second connection terminal 162 are slightly spaced apart from each other due to the connection slope 153 provided in the first connection terminal 152, the lever switch 140 is turned off To be maintained.

When the door 101 is opened, the brake connecting member 143 connected to the brake engaging portion 154 is stretched so that the brake elastic member 174 provided on the brake 170 due to the elastic force of the brake elastic member 174 ) Is compressed. The first stopping member 172 moves toward the center of the brake 170 in which the dewatering motor 43 is located and the second stopping member 173 is also moved to the dewatering motor 43 Since the second stop member 173 contacts and the frictional force acts on the dehydrating motor 43, the dehydrating motor 43 is stopped due to the frictional force.

Conventionally, in order to adjust both the operation of the brake and the opening / closing of the door, a separate component has to be used. Thus, the structure of the panel is complicated and moisture is likely to penetrate into the electric component. However, in the case of the present invention, since the operation of the brake 170 due to opening and closing of the door 101 and the electrical connection of the dewatering motor 43 can be controlled with the lever switch 140, In addition to the reduction of the production cost due to the reduction of the parts, it is possible to prevent the defects due to moisture penetration into the electrical parts of the washing machine.
