- a conventional dishwasher is a machine that sprays washing water on dishes placed in a tub to remove foreign matter, such as food scraps left on the dishes.
- the dishwasher is operated based on a washing cycle that sprays washing water mixed with detergent in a tub that contains dishes, in order to remove foreign matter left on the dishes.
- the dishwasher may also heat the washing water to improve performance.
- a rinsing cycle occurs which sprays washing water that is not mixed with the detergent in the tub to remove any remaining foreign matter.
- a drying cycle takes place, which dries the dishes.
- more than one spraying arm and at least one rack are provided in a single tub of the conventional dishwasher.
- a dishwasher usually has an upper rack and a lower rack in a bi-level configuration within the tub.

- the sump heater 290 may be operated.
- the sump heater 290 can be turned on for a predetermined time period.
- the washing cycle (W) may be preset to be performed for a preset time period and may continue until the temperature of the water contained in the sump 200 reaches a preset temperature.
- the washing water used in the washing cycle (W) can be drained and water can be newly supplied (DS).
- the newly supplied water may be cold, warm, or heated. Because the temperature of the sump 200 may have increased from the sump heater 290 being turned on during the washing cycle (W), the newly supplied water may not drop in temperature drastically as can occur during the washing cycle (W).
- the electric heater 310 of steam generator 300 can be preheated during the draining of the washing water and the supplying of the new water (DS).
- Preheating steam generator 300 can advantageously allow steam to be supplied and sprayed during rinse cycle (R) after (or immediately after) the draining of the washing water and the supplying of new water (DS).
- steam can be sprayed in a primary period of the rinsing cycle (R) to enhance washing efficiency. Soaking and washing dishes using steam enables new dishes and old (unused) dishes with substantially smaller washing loads to be washed quickly and efficiently.
- the supplying of steam (st) and spraying of water (ws) can be performed sequentially.
- the temperature of the washing compartment 150 and the temperature of the sump 200 may be increased by the steam sprayed during the supplying of the steam (st) stages.
- the supplying of the steam (st) may be performed for a predetermined time period, or until the temperature of the washing compartment 150 or the sump 200 reaches a preset temperature (T 1 ).
- T 1 a preset temperature
- the supplying of the steam (st) can occur for approximately 5 (five) or more minutes.
- the spraying of the water (ws) can start.
- the sump heater 290 may be turned on, as may occur during the washing cycle (W).
- the temperature of the water during the washing cycle (W) and the rinsing cycle (R) may increase gradually.
- the overall washing time can be reduced.
- the water used during the rinsing cycle (R) may be heated by the sump heater 290 up to a preset temperature (T 2 ), which can be approximately 60° C.
- T 2 a preset temperature
- preheating steam generator 300 during the draining of the water and the supplying of the new water (DS) (hereinafter “drained/supplied” or “DS”) can be used to drained which has been used and new clean water may be supplied to the washing compartment 150 and/or sprayed.
- FIG. 3 illustrates an exemplary method which may be employed to control a dishwasher according to an embodiment of the invention.
- the supplying of the steam (st) can occur before the spraying of the water (ws) during the rinsing cycle (R), and can overlap with the overall draining of the water and the supplying of the new water cycle (DS).
- the overall washing time can be reduced when the supplying of the steam (st) starts at substantially the same time as the draining of the water and the supplying of the new water (DS).
- the steam generator 300 can be preheated during the washing cycle (W) and the steam can be supplied to the washing compartment 150 from the steam generator 300 at approximately the same time as the draining of the water and the supplying of the new water (DS).
- the sump heater 290 can be turned on during the spraying of the washing water (ws) to improve efficiency and/or reducing washing time.
- FIG. 4 illustrates an exemplary method that may be employed to control a dishwasher.
- the supplying of the steam (st) can occur before the spraying of the water (ws) during the rinsing cycle (R) and can overlap a portion, such as a preset period, of the draining of the water and the supplying of the new water cycle (DS).
- the steam can be preheated during the washing cycle (W) and supplied to the washing compartment 150 before the draining of the water and the supplying of the new water (DS) is complete.
- operating the steam heater 310 of the steam generator 300 and the sump heater 290 substantially simultaneously during the washing cycle (W) can be inefficient and place a heavy load on the dishwasher.
- the preheating of the steam heater 310 can start just before the washing cycle (W) is complete, and the steam can then be supplied (st) to the washing compartment 150 in the middle of the draining of the water and the supplying of the new water cycle (DS).
- This configuration can reduce electrical overload, or reduce the amount of power drawn by the dishwasher and increase its efficiency, when operating the steam generator 300 and the sump heater 290 .
- the steam can begin to be supplied (st) to the washing compartment 150 after or shortly after the washing cycle (W) completes.
- steam can be supplied (st) before or shortly before the draining of the water and the supplying of the new water (DS) completes.
- the preheating of the steam generator 300 using the steam heater 310 can start in the middle of the washing cycle (W).
- the supplying of the steam (st) can start at substantially the same time as the draining of the water and the supplying of the new water cycle (DS) and/or or before (DS) completes.
- Preheating of the steam generator 300 can overlap with the time that upper spraying arm 230 and lower spraying arm 220 spray water, which may be heated by the sump heater 290 , in an alternating manner.
- the supplying of the steam (st) using the steam generator 300 may then overlap with the time that the spraying of the water (ws) in the washing cycle (W) occurs and/or before the draining of the water and the supplying of the new water cycle (DS) occurs.
- the steam generator 300 and the sump heater 290 can then be operated substantially simultaneously or partially overlap for a preset time period.
- the sump heater 290 may be turned on continuously.
- the sump heater 290 can also be turned off during the supplying of the steam (st) to the washing compartment 150 using the steam generator 300 .
- the water draining and the new water supplying cycle (DS) cycle may occur for a substantially short period of the overall operation of the dishwasher.
- the preheating of the steam generator 300 overlaps with the time that the water draining and the new water supplying (DS) cycle starts, the overall washing time and efficiency can be improved.
- the supplying of the steam (st) starts at the beginning, middle, during, or after the water draining and the new water supplying of the (DS) cycle, the overall washing time and efficiency can be improved.
- the spraying of the rinsing water (ws) can start.
- the sump heater 290 can be turned on during the spraying of the rinsing water (ws) to improve efficiency.
- the time period to supply the steam (st) and the spray the water (ws) during the rinsing cycle (R) can be determined.
- the overall washing time can be determined.
