Abstract

The present invention provides a laundry treating apparatus including a cabinet, a control panel having a power key and a display panel provided to one side of the cabinet, a display MICOM for controlling a frame to be displayed on a display of the display panel, a main MICOM for putting a load into operation according to a washing stroke applied thereto, and a standby power MICOM for generating a power supply signal to supply power to the display MICOM and the main MICOM in response to a power key applied signal generated as the power key is operated.

First claim

What is claimed is:

1. A laundry treating apparatus comprising:
a cabinet;
a control panel located on the cabinet, the control panel including a display panel and a power key generating a power key applied signal by the user pressing the power key down during a standby state;
a main MICOM to apply an electrical load according to a washing stroke applied thereto;
a display MICOM to control the display panel;
a standby power MICOM to generate a power supply signal to control the supply of power to the display MICOM and the main MICOM in response to the power key applied signal from the power key;
a power IC receiving the power supply signal from the standby power MICOM, and supplying DC power to the display MICOM in response to the received power supply signal;
a sub-SMPS converting AC power to DC power and supplying DC power to the standby power MICOM and the power IC;
a main SMPS converting AC power to DC power and supplying DC power to the main MICOM; and
a relay receiving the power supply signal from the standby power MICOM and controlling the supply of AC power to the main-SMPS in response to the received power supply signal,
wherein the standby state is a state in which the power key applied signal is not generated by the power key and in which the standby power MICOM and the power IC is supplied DC power by the sub-SMPS, the relay is supplied AC power, and the main MICOM and the display MICOM are not supplied DC power.

2. The laundry treating apparatus of claim 1 , wherein the control panel is a touch panel.

3. The laundry treating apparatus of claim 1 , wherein the relay includes a boot relay and a main relay,
wherein the boot relay controls the supply of power to the main relay in response to the power supply signal, and the main relay controls the supply of power to the main SMPS in response to the power supply signal, and
wherein the power supply signal to the main relay is delayed relative to the power supply signal to the boot relay by a predetermined time period.

4. The laundry treating apparatus of claim 1 , wherein the power IC supplies the power to the display panel in response to the received power supply signal.

5. The laundry treating apparatus of claim 1 , wherein the control panel is located to one side of the cabinet.

6. The laundry treating apparatus of claim 1 , wherein the control panel is located on a top side of the cabinet.

7. The laundry treating apparatus of claim 1 , wherein the control further comprises a start key to signal a washing course selection from a user.

8. The laundry treating apparatus of claim 7 , wherein the washing course selection comprises one or more washing strokes.

9. The laundry treating apparatus of claim 7 , wherein the washing course selection at least partially defines the electrical load of the laundry treating apparatus.

10. The laundry treating apparatus of claim 1 , wherein the main MICOM is provided on a main PCB.

11. The laundry treating apparatus of claim 1 , wherein the display MICOM is provided to a display PCB.

12. The laundry treating apparatus of claim 1 , wherein the standby power MICOM is provided on a base PCB.

13. The laundry treating apparatus of claim 1 , wherein the sub-SMPS and the main-SMPS are electrically insulated.

14. The laundry treating apparatus of claim 10 , wherein the sub-SMPS and the main-SMPS are provided on the main PCB.
