Abstract

A laundry treatment apparatus may be provided that includes a cabinet having an input opening, a door including a door frame, a hinge unit, and a control panel, a cabinet connector at the cabinet to transmit and receive at least one of power and a control signal and a door connector separably coupled to the cabinet connector to connect the control panel to the cabinet connector.

First claim

What is claimed is:

1. A laundry treatment apparatus comprising:
a cabinet having an input opening;
a laundry receptacle configured to store laundry received through the input opening;
a door including a door frame configured to open or close the input opening, a hinge unit configured to rotatably couple the door frame to the cabinet, and a control panel at the door frame to input a control command or output control information;
a cabinet connector at the cabinet, the cabinet connector being configured to transmit and receive at least one of power and a control signal; and
a door connector to separably couple to the cabinet connector, the door connector being configured to couple the control panel to the cabinet connector, wherein the door connector is coupled to the hinge unit, and
wherein the cabinet connector is exposed from a surface of the cabinet so as to be coupled to the door connector when the door is assembled to the cabinet,
wherein the cabinet connector includes:
a power socket to couple to a power supply device at the cabinet, and
a communication socket to couple to an information processing device at the cabinet to control the control panel; and
wherein the door connector includes:
a power plug to couple to the power socket so as to supply power to the control panel;
a communication plug to couple to the communication socket so as to couple the control panel to the information processing device;
a connector body to couple to the hinge unit;
a receiving recess in the connector body to provide a space to receive the power plug and the communication plug; and
a wire guide to extend from the connector body to the door frame, the wire guide configured to receive a wire, and the wire to couple the power plug and the communication plug to the control panel.

2. The apparatus according to claim 1 , wherein the cabinet connector to couple to at least one of a power supply device and an information processing device for control of the control panel,
wherein the power supply device is provided at the cabinet, and
wherein the information processing device is provided at the cabinet.

3. The apparatus according to claim 1 , wherein the hinge unit includes:
a hinge body to couple to the cabinet, the door connector to couple to the hinge body; and
a hinge arm at the hinge body, the door frame to be rotatably coupled to the hinge arm.

4. The apparatus according to claim 3 , wherein the wire guide includes:
a guide body configured to penetrate the hinge body and to communicate with the receiving recess; and
a wire receiving region defined in a longitudinal direction of the guide body to provide a space to receive the wire.

5. The apparatus according to claim 1 , wherein the cabinet connector includes a first connector and a second connector located respectively at both facing sides of the input opening,
the door frame includes a plurality of seat planes defined respectively at both facing ends of the door frame to provide a space for coupling of the hinge unit.

6. The apparatus according to claim 5 , wherein a first one of the seat planes has a same shape as a second one of the seat planes rotated by 180 degrees about a reference point in the door frame; and
the first connector has a same cross sectional shape as the second connector rotated by 180 degrees about the reference point.

7. The apparatus according to claim 5 , wherein a first one of the seat planes has a same shape as a second one of the seat planes rotated by 180 degrees about a projection point, the projection point based on a center point of the input opening to the door frame; and
the first connector has a same cross sectional shape as the second connector rotated by 180 degrees about the projection point.

8. The apparatus according to claim 7 , wherein the door connector further includes:
a panel terminal in the connector body including the power plug and the communication plug so as to couple to each of the first connector and the second connector, the panel terminal to couple to the control panel via a wire; and
wherein the wire guide configured to receive the wire so as to couple the panel terminal to the control panel.

9. The apparatus according to claim 8 , wherein the hinge unit further includes:
a first arm and a second arm at the hinge body, the first arm and the second arm to be rotatably attached to a corresponding one of the seat planes; and
a guide fixing recess between the first arm and the second arm, the wire guide being provided at the guide fixing recess.

10. The apparatus according to claim 9 , wherein the hinge body has an axially symmetrical shape about a line passing through the guide fixing recess.

11. The apparatus according to claim 10 , wherein the door frame includes:
an outer frame provided with the control panel and the seat planes; and
an inner frame provided with at least one guide receiving recess configured to receive the wire guide, at least one first arm receiving recess configured to receive the first arm, and at least one second arm receiving recess configured to receive the second arm, and the outer frame to couple to the inner frame, and
wherein the guide receiving recess, the first arm receiving recess and the second arm receiving recess are at each of both facing ends of the inner frame.

12. The apparatus according to claim 11 , further comprising:
a hook configured to be fitted at the guide receiving recess not provided with the wire guide among the guide receiving recesses respectively formed at both facing ends of the inner frame; and
a hook fastening piece provided to the cabinet, the hook fastening piece being configured to receive the hook.

13. The apparatus according to claim 12 , wherein the hook fastening piece includes:
a body to couple to the cabinet to prevent the first connector or the second connector not coupled to the door connector from being outwardly exposed; and
a hook receiving hole at the body, the hook to couple to the hook receiving hole.

14. An apparatus comprising:
a cabinet having an input opening;
a door frame configured to open or close the input opening;
a hinge unit configured to couple the door frame to the cabinet;
a control panel at the door frame;
a cabinet connector at the cabinet to transmit and receive at least one of power and a control signal, wherein the cabinet connector to couple to at least one of a power supply device and a processing device for control of the control panel, wherein the power supply device is provided at the cabinet, and wherein the processing device is provided at the cabinet; and
a door connector to couple to the cabinet connector, the door connector to couple the control panel to the cabinet connector, wherein the door connector is coupled to the hinge unit, and
wherein the cabinet connector is exposed from a surface of the cabinet so as to be coupled to the door connector when the door is assembled to the cabinet,
wherein the cabinet connector includes a first connector and a second connector located respectively at both facing sides of the input opening, and the door frame includes a plurality of seat planes defined respectively at both facing ends of the door frame to provide a space for coupling of the hinge unit,
