Description
- This application claims the benefit of the Korean Patent Application Nos. 10-2005-0057968 and 10-2005-0057970 filed on Jun. 30, 2005, which are hereby incorporated by reference as if fully set forth herein.

- The present invention relates to a washing machine, and more particularly, to a method for controlling a course in a washing machine so as to improve the efficiency in decomposition of protein and anti-bacteria effect.
- 2. Discussion of the Related Art
- Generally, a washing machine is one of widely used electric home appliances. The washing machine is an apparatus for removing contaminants from the laundry such as clothes by an emulsification of detergent, a friction of a washing water motion generated by a drum rotation, and an impact applied to the laundry.
- The generally used washing machine is largely classified into a pulsator type, an agitator type, and a drum type. Based on whether a washing tub is separated from a spin-drying tub or not, the washing machine may be divided into a separation type and an automatic type.
- In general, a washing operation is performed in a course of supplying the detergent and the washing water to the laundry to be washed such that contaminants can be removed from the laundry by a chemical action of the detergent contained in the washing water and a physical action of a blade of the washing machine.
- Then, a rinsing operation is performed in a course of supplying washing water containing no detergent therein such that the detergent and contaminants can be rinsed out of the laundry. A spin-drying operation is performed in a course of rotating the washing tub at a high speed after completing the rinsing operation such that moisture can be removed from the laundry.
- In the general washing machine, a user can selectively set the washing conditions relating operation time periods of washing, rinsing, and spin-drying according to the kind and amount of laundry.
- For convenience of the user, the washing machine has a memory in which various course programs for an automatic washing process are previously stored. Accordingly, the user can select the corresponding course program from the various programs previously stored in the memory according to the kind and amount of laundry to be washed.
- That is, the various course programs, for example, a centrifugal washing course, a high-consistency washing course, a pre-washing course, a vibration course, a soaking-type washing course, and a wool-laundry washing course, are previously stored in the memory of the washing machine. Accordingly, the user selects the desired course program in the washing machine, and performs the automatic washing stroke according to the desired course program.
- However, even though the various course programs are provided in the washing machine, the long-time used clothes may be discolored or yellowed due to the contaminants of protein components and the limitation in chemical action of the detergent.
- To remove the contaminants of protein components from the laundry, it is necessary to increase a mechanical power applied to the laundry by generating a strong rotary power with the blade or spin-drying tub. In this case, the laundry may be damaged or entangled due to the strong rotary power.

Thus, it is difficult to destroy the bacilli of the laundry with the related art washing machine using the cold or warm water. Especially, if the bacilli are left in the washed laundry, the bacilli may damage the user's skin health, and the user may feel displeased and uncomfortable.
- Accordingly, the present invention is directed to a method for controlling a course of a washing machine that substantially obviates one or more problems due to limitations and disadvantages of the related art.
- An object of the present invention is to provide a method for controlling a course of a washing machine to remove bacilli as well as protein contaminants from a washing tub and the laundry.

- In this state, according as the
heater 41 is turned on, the washing water is heated to the first preset temperature T1. That is, the washing stroke for removing dirt from the laundry is performed during the first preset time period t1 (S20). - At this time, the anti-yellow course controls the
heater 41 to be turned on/off alternatively and repetitively, to thereby maintain the first preset temperature T1 during performing the anti-yellow course. - In the meantime, if the user selects not the anti-yellow course but a normal course, a preset washing stroke time period t0 is selected, and the
heater 41 is turned off, whereby the washing stroke is performed during the preset washing stroke time period t0 in state of turning off the heater 41 (S30). - At this time, preferably, the first preset time period t1 of the anti-yellow course is longer than the preset washing stroke time period t0 of the normal course.
- On completing the washing stroke of the corresponding preset time period according to the washing course selected by the user, rinsing and spin-drying strokes (S40 and S50) are performed in sequence. The rinsing stroke (S40) is performed to rinse the laundry in the clean water, to thereby remove detergent and contaminants from the laundry. The spin-drying stroke (S50) is performed by rotating the drum (inner and outer tubs) at a high speed, to thereby remove the moisture from the laundry.
- In detail, the washing stroke of the anti-yellow course will be explained with reference to
FIG. 5 . - First, after measuring the amount of laundry (S21), the water level is determined corresponding to the measured amount of laundry.

heater 41 is operated and the rotation and stop of the drum occur in alternation and repetition (S23 and S24). - At this time, the
water temperature sensor 43 periodically reads the temperature of washing water heated by theheater 41, whereby theheater 41 is repetitively turned on/off to thereby maintain the first preset temperature T1 of the washing water during performing the washing stroke. - Preferably, the washing water for the anti-yellow course is maintained at a temperature of 40° C. or more, at which the decomposition of protein is activated.
- The anti-bacteria course of the present invention will be explained with reference to
FIGS. 6 and 7 . - First, after the user puts the laundry into the inside of the washing machine, the user selects the desired stroke course. At this time, whether the user selects the anti-bacteria course or not is sensed (S60).
- If the user selects the anti-bacteria course, a second preset time period t2 is determined as a washing stroke time, and a second preset temperature T2 is determined as a temperature of the washing water for the anti-bacteria course. That is, the washing stroke for removing dirt and bacilli from the laundry is performed during the second preset time period t2 at the second preset temperature T2 (S70).
- In the meantime, if the user selects not the anti-bacteria course but a normal warm-water course, a washing stroke time period t0 and a temperature T0 of warm washing water, which are previously set according to the normal warm-water course, are selected. In this state, the washing stroke is performed during the time period t0 at the temperature T0 of the washing water (S80).
- Preferably, the second preset time period t2 of the anti-bacteria course is longer than the time period t0 of the normal warm-water course, and the second preset temperature T2 of the anti-bacteria course is higher than the temperature T0 of the normal warm-water course.
- Especially, the second preset temperature T2 of the anti-bacteria course is set above the boiling point, for example, about 95° C. or more, at which the bacilli of the laundry is destroyed.
- After completing the washing stroke of the preset time period according to the washing course selected by the user, rinsing and spin-drying strokes (S90 and S100) are performed in sequence. The rinsing stroke (S90) is performed to rinse the laundry in the clean water, to thereby completely remove the detergent and contaminants from the laundry. The spin-drying stroke (S100) is performed by rotating the drum (inner and outer tubs) at a high speed, to thereby remove the moisture from the laundry.
- In detail, the washing stroke of the anti-bacteria course will be explained with reference to
FIG. 7 . - First, after measuring the amount of laundry (S71), the water level is determined corresponding to the measured amount of laundry.
- After the water is supplied to the determined level (S72), counting of washing time is started and the
heater 41 is turned on, at the same time. - During the second preset time period t2, the washing stroke is performed in state of that the
heater 41 is operated and the rotation and stop of the drum occur in alternation and repetition (S73 and S74). - At this time, the
water temperature sensor 43 periodically reads the temperature of washing water heated by theheater 41, whereby theheater 41 is repetitively turned on/off to thereby maintain the second preset temperature T2 of the washing water during performing the washing stroke. - The washing water is heated to the second preset temperature T2, and the heated washing water of high temperature is used for the washing stroke of the laundry, to thereby completely destroy the bacillus of the laundry.
- As mentioned above, the method for controlling the course of the washing machine according to the present invention has the following advantages.
