Abstract

A laundry treating apparatus including a drum holding a washing object, a drive unit rotating the drum, a drive controller, a display unit with an input unit accepting drive unit control orders, and a display communicating treating progress of the washing object. The display unit having a controller with an input data processing unit, an output data processing unit, and a processing unit control program for running the input and output data processing units. The laundry treating apparatus further including a system managing unit enabling the drive controller and display unit to exchange data with the display unit controller, ordering operation of the display unit, and running the processing unit control program, a list storage unit storing a program list the display unit controller runs, and a monitoring unit for initializing the system managing unit if the processing unit control program is not at the list storage unit.

First claim

What is claimed is:

1. A laundry treating apparatus comprising:
a drum to hold a washing object;
a drive unit including a motor to rotate the drum;
a drive controller to control the drive unit;
a display unit including an input unit to receive a drive unit control order and a display to communicate a treating progress of the washing object;
a display unit controller including:
an input data processing unit to receive the control order from the input unit and to provide the control order to the drive controller,
an output data processing unit to receive drive data from the drive controller and to provide the drive data to the display, and
a processing unit control program to run the input data processing unit and the output data processing unit;

a system managing unit to enable the drive controller and the display unit to exchange data with the display unit controller, and to order operation of the display unit and running of the processing unit control program;
a list storage unit including a program list of programs the display unit controller runs; and
a monitoring unit configured to detect whether the list storage unit includes the processing unit control program and configured to initialize the system managing unit when the list storage unit does not include the processing unit control program,
wherein the display unit and the display unit controller are initialized when the initialization of the system managing unit is in progress,
wherein the system managing unit is put into operation again after its operation is stopped, thereby the initialization of the system managing unit reboots the display unit and the display unit controller after their operation are stopped, and
wherein even if a malfunction occurs at the display unit controller, the drive unit and the drive controller continue to operate.

2. The laundry treating apparatus of claim 1 , wherein the drive unit and the drive controller operate to perform a washing or drying process having been performed continually when the initialization of the system managing unit is in progress.

3. The laundry treating apparatus of claim 1 , wherein the display is an LCD panel or LED panel controlled by the output data processing unit, and
the input unit is a touch panel integrated in the display to provide a control signal to the input data processing unit in response to a signal from the touch panel.

4. The laundry treating apparatus of claim 1 , wherein the drive unit further includes:
an air supply unit to supply air to an inside of the drum.

5. The laundry treating apparatus of claim 1 , further comprising:
a tub having the drum housed therein to hold washing water, and
the drive unit further includes
a water supply unit to supply the washing water to the tub, and
a drain unit to remove the washing water from the inside of the tub.

6. The laundry treating apparatus of claim 5 , wherein the drive unit further includes:
an air supply unit to supply the air to the inside of the tub.

7. The laundry treating apparatus of claim 6 , wherein the tub further includes:
a duct to discharge the air from the inside of the tub to an outside of the tub and to re-supply the air to the tub, and
the air supply unit is provided to the duct to dehumidify and heat the air discharged from the duct.

8. The laundry treating apparatus of claim 7 , wherein the air supply unit includes:
a heater provided in the duct to heat the air in the duct,
a fan provided in the duct to move the air in the tub, and
a cooling water supply unit to condense the air discharged from the tub.
