However, the present invention is not limited to this, and the first terminal 100 and the second terminal 200 may be electrically connected to each other even if they are not in direct contact with each other through short-range wireless communication. Hereinafter, the connection structure by contact will be mainly described.

The first terminal 100 and the second terminal 200 may be disposed in the cabinet 10 and the door 20, respectively. The first terminal 100 and the second terminal 200 may be disposed at positions corresponding to each other so that the first terminal 100 and the second terminal 200 can be contacted when the door 20 is closed. Further, when the door is opened, the first terminal 100 and the second terminal 200 can be disposed at a non-contact position. That is, the first terminal 100 and the second terminal 200 may be disposed at positions where the first terminal 100 and the second terminal 200 are in contact or non-contact with each other. As described above, since the first terminal 100 and the second terminal 200 can be electrically connected by contact, they can be electrically connected or disconnected according to the opening and closing of the door. Specifically, the first terminal 100 and the second terminal 200 are electrically disconnected when the door is opened, and can be electrically connected when the door is closed.

According to one embodiment of the present invention, the terminals and electrical components can be electrically and physically connected by wires. At this time, the wire may include a first wire and a second wire. Specifically, the first electrical component may be connected to the first terminal 100 by a first wire, and the second electrical component may be connected to the second terminal 200 by a second wire. Further, the first wire may be disposed along the outer rim of the front frame, and the second wire may be disposed along the circumferential direction of the door. As a result, the wire is inserted into the inside of the door and the cabinet, so that the wire can be exposed to the outside to prevent deterioration of the beauty of the washing machine.

Since the terminal and the electrical component can be electrically connected through the wire, when the first terminal 100 and the second terminal 200 are electrically connected, the first electrical component and the second electrical component can also be electrically connected. That is, the first electrical component and the first terminal 100 are electrically connected by the first wire, the first terminal 100 and the second terminal 200 are electrically connected by contact, and the second terminal 200 ) And the second electrical component can be electrically connected by the second wire. According to the present invention, when the first electrical component is a power supply, the second electrical component provided in the door can be supplied with power from a power supply provided inside the cabinet even if a separate power supply is not provided in the door. The first terminal 100 and the second terminal 200 are separately disposed in the cabinet and the door and a wire connection structure such as a wire or a cable is provided between the first terminal 100 and the second terminal 200 Not provided. Therefore, the first electrical component and the second electrical component can be electrically connected without using a complicated wired connection structure, such as inserting a wire into the hinge assembly. Since no separate line is provided to connect the first terminal 100 and the second terminal 200, the power connection structure according to the present invention can be regarded as a wireless connection structure. As a result, it is possible to solve the problems caused by the wired connection structure. For example, in the case of a structure in which a power line is inserted into a door hinge, a power line is twisted or bent due to repetitive hinge rotation, resulting in breakage of a power line, complicated product repair process due to disconnection, There is a problem in that time is lost when assembling the product due to wire insertion. However, the wireless connection structure according to the present invention can solve such a problem. In addition, since the first electrical component and the second electrical component are electrically connected or disconnected according to opening and closing of the door, a washing machine safe for the user can be provided. Specifically, when the door is opened, the first terminal 100 and the second terminal 200 are electrically disconnected from each other, thereby electrically disconnecting the first electrical component and the second electrical component. Therefore, The electric appliance or the terminal is brought into contact with the electric appliance, the electric appliance can be safely used.
