Abstract

The present invention relates to a device for handling laundry and a control method thereof, wherein the device for handling laundry, equipped with a plurality of washing units that wash independently of one another, sets a washing course in order that, when washing is being carried out by a first washing unit and a second washing unit at the same time, a specific operation is not carried out by the first washing unit and the second washing unit at the same time, the washing course being set by combining the washing courses of the plurality of washing units, and thus, operational delays resulting from simultaneous operation are prevented, vibrations are reduced, momentary increases in power consumption are prevented, protecting the device for handling laundry and improving energy consumption efficiency.

First claim

The invention claimed is:

1. A device for handling laundry comprising:
a first washing unit that includes a first tub and a first communication unit; and
a second washing unit that includes a second tub and a second communication unit, and which operates independently of the first washing unit;
a first controller for controlling the first washing unit; and
a second controller for controlling the second washing unit,
wherein the first controller receives data on a second washing course of the second washing unit from the second controller through the first and the second communication units when the first washing unit and the second washing unit operate simultaneously, and generates a third washing course configured to not perform a specific operation simultaneously based on a first washing course of the first washing unit and the second washing course of the second washing unit and transmits data on the third washing course to the second controller through the first and the second communication units and controls the first washing unit according to the third washing course,
wherein the third washing course is a combination of the first washing course and the second washing course and is set such that the first and the second washing units respectively perform set operations,
wherein the first controller generates the third washing course so that water supply, spin-dry, drying operation, and operation according to wash water heating are not simultaneously performed.

2. The device for handling laundry of claim 1 , wherein the first controller classifies a plurality of partial processes included in the first washing course and the second washing course, and then reconfigures the plurality of partial processes so that operations having a high power consumption are not overlapped with each other, and generates the third washing course which is a combination of the first washing course and the second washing course.

3. The device for handling laundry of claim 1 , wherein the first controller is configured to firstly perform a partial process of one washing unit, among the first washing unit and the second washing unit, having a start time that takes priority with respect to a partial process corresponding to the specific operation, among a plurality of partial processes included in the first washing course and the second washing course, and to delay operation of the partial process of another one washing unit among the first washing unit and the second washing unit, to set the third washing course.

4. The device for handling laundry of claim 3 , wherein the first controller sets the third washing course so as to perform a soaking process or a laundry untangling process during waiting due to an operation delay.

5. The device for handling laundry of claim 4 , wherein the first controller generates the third washing course by giving priority to a washing process as a first priority, a rinsing process as a second priority, a rinsing spin-dry process as a third priority, and a final spin-dry process as a fourth priority, with respect to the plurality of partial processes, and enabling an operation having a high-priority to be performed first.

6. The device for handling laundry of claim 1 , wherein the first controller generates the third washing course so that an operation of a washing course having a longer total washing time, among the first washing course and the second washing course, is performed first.

7. The device for handling laundry of claim 1 , wherein the first controller sets the third washing course so that the first washing unit and the second washing unit terminate simultaneously.

8. The device for handling laundry of claim 1 , wherein the first controller generates the third washing course so that operations of drying and washing, wash water heating and washing, drying and rinsing, wash water heating and rinsing, drying and spin-dry, wash water heating and spin-dry, and spin-dry and spin-dry are not performed simultaneously in the first washing unit and the second washing unit.

9. The device for handling laundry of claim 1 , wherein the first controller generates the third washing course when the second washing course of the second washing unit is inputted within a certain time, after the first washing course is inputted.

10. The device for handling laundry of claim 1 , wherein the first controller generates the third washing course, when a new washing course is inputted to another washing unit, among the first washing unit and the second washing unit, before one washing unit, among the first washing unit and the second washing unit starts operation according to inputted washing course and an initial water supply is completed.

11. The device for handling laundry of claim 1 , further comprising an input unit having a twin washing key,
wherein the first controller waits for a certain time when the twin washing key is inputted after inputting the first washing course, and generates the third washing course when the second washing course is inputted within the certain time.

12. The device for handling laundry of claim 11 , wherein, when the second washing course is inputted and the twin washing key is inputted while the first washing unit operates according to the first washing course, the first controller combines remaining operation according to the first washing course with the second washing course to generate the third washing course.

13. The device for handling laundry of claim 1 , further comprising:
a first display unit for outputting an operation state of the first washing unit and the first washing course or the third washing course; and
a second display unit for outputting an operation state of the second washing unit and the second washing course or the third washing course.

14. The device for handling laundry of claim 13 , wherein the first display unit and the second display unit output a guide message on whether to apply the third washing course when the third washing course is generated.

15. The device for handling laundry of claim 1 , wherein, when the first controller receives error information from the second controller while controlling the first washing unit according to the third washing course, the first controller ignores the third washing course and performs operation according to the first washing course.

16. The device for handling laundry of claim 1 , wherein, when the second controller receives error information from the first controller while controlling the second washing unit according to the third washing course, the second controller ignores the third washing course and performs operation according to the second washing course.
