Abstract
Official abstract text for this publication.
A washing machine in which a first main heater is not driven while wash water stored in a first tub and wash water stored in a second tub are simultaneously heated, and a method of controlling the same. A washing machine includes: a first tub configured to store wash water; a first main heater configured to heat wash water stored in the first tub; a first sub heater configured to heat wash water stored in the first tub; a second tub configured to store wash water; and a second heater configured to heat wash water stored in the second tub, wherein a power consumption required to drive the first main heater is greater than a power consumption required to drive the first sub heater, and the first main heater is not driven while wash water stored in the first tube and wash water stored in the second tub are simultaneously heated.
First claim
Opening claim text (preview).
What is claimed is: 1. A washing machine comprising: a first tub configured to store wash water; a first main heater configured to heat wash water stored in the first tub; a first sub heater configured to heat wash water stored in the first tub; a second tub configured to store wash water; a second heater configured to heat wash water stored in the second tub; and a controller configured to control the first main heater not to operate while the controller simultaneously controls the first sub heater and the second heater to operate, wherein a power consumption required to operate the first main heater is greater than a power consumption required to operate the first sub heater. 2. The washing machine of claim 1 , wherein the first tub is disposed under the second tub. 3. The washing machine of claim 1 , wherein the first tub has a capacity of wash water greater than that of the second tub. 4. The washing machine of claim 1 , wherein the controller is configured to simultaneously control the first sub heater and the second heater to operate to increase temperatures of wash water stored in the first tub and wash water stored in the second tub to a predetermined first target temperature and a predetermined second target temperature respectively. 5. The washing machine of claim 4 , wherein when the temperature of wash water stored in the second tub reaches the second target temperature before the temperature of wash water stored in the first tub reaches the first target temperature, the controller controls the second heater not to operate and simultaneously controls the first main heater and the first sub heater to operate.
