- a level of detergent water is detected by the level detection unit 17, and the controller determines whether or not the level of the detergent water is a first preset level (the maximum level of the detergent water capable of preventing water supplied into the tub from flowing into the rotational drum, and corresponding to about 1/4 of a level of detergent water in a general washing operation; a level detected by the first level sensor) (S508).
- a first preset level the maximum level of the detergent water capable of preventing water supplied into the tub from flowing into the rotational drum, and corresponding to about 1/4 of a level of detergent water in a general washing operation; a level detected by the first level sensor
- the controller 130 turns off the water supply valve 24, the assistant water supply valve 32 and the detergent liquid input valve 33 to stop supply of detergent concentrate liquid and water (S510).
- air is supplied from the air supply device 60 to the detergent water formed of the mixture of detergent concentrate liquid and water to generate the bubbles (S512), followed by washing operation.
- the air supply device 60 generates the bubbles in such a way that, after being supplied from the air motor 61, air is dispersed through the porous member 62 via the air supply line 62, and is then forced into the detergent water as the mixture of detergent concentrate liquid and water through the air holes 64, generating the bubbles.
- the bubbles After being generated between the tub 11 and the rotational drum 12 via the air supply device 60, the bubbles are supplied into the rotational drum 12 through the holes or a front section of the rotational drum 12, and finally dispersed into the overall space of the rotational drum 12 after a predetermined period of time (about three minutes), enabling the laundry to be washed only with the bubbles within the rotational drum 12.
- an RPM and operation rate of the rotational drum 12, and a washing period therein be less than or equal to values set in each washing course corresponding to the load.
- the bubbles can act as a cushion with respect to fall of the laundry and friction between the laundry caused by rotation of the rotational drum 12, thereby preventing the texture of the laundry from being damaged due to the friction between the laundry.
- the level detection unit 17 detects a level of the lowering detergent water, and determines whether or not the level of the detergent water reaches a second preset level (the minimum level of detergent water required for generation of the bubbles; a level detected by the second level sensor) (S518).
- the process returns to the operation of S512 to continue the washing operation via rotation of the rotational drum 12 along with generation of the bubbles until the level of the detergent water reaches the second level.
- the process returns to the operation of S504 to start supply of detergent concentrate liquid and water corresponding to a reduced amount of the detergent water.
- the water supply valve 24 and the assistant water valve 32 are opened with operation of the water supply device 20, allowing water to flow through the assistant water supply line 31 instead of the detergent supply device 19, and then to be additionally supplied into the tub 11 through the water supply nozzle 26 via the connection line 25.
- the detergent input valve 33 is opened, allowing the detergent concentrate liquid of a high detergent concentration in the detergent dissolving device 30 to be also supplied into the tub 11.
- the predetermined amount of detergent concentrate liquid in the detergent dissolving device 30 is also supplied upon additional supply of the water.
- the amount of the detergent concentrate liquid supplied from the detergent dissolving device 30 is so determined that, when 1 drop of detergent concentrate liquid having a predetermined concentration is supplied into the tub 11, the water is also supplied at an amount proportional to this detergent concentrate liquid. For example, assuming an amount of detergent water required by the tub 11 is 10, the controller controls the washing machine to supply 1 drop of detergent concentrate liquid and an amount of water proportional to this detergent concentrate liquid into the tub 11, and assuming an amount of detergent water required by the tub 11 is 20, the controller controls the washing machine to supply 2 drops of detergent concentrate liquid and an amount of water proportional to this detergent concentrate liquid, that is, two times of the above case, into the tub 11.
- control method of the present invention enables the bubble washing operation to be effectively performed always using the bubbles having the predetermined detergent concentration by allowing the predetermined amount of detergent concentrate liquid to be supplied together with additional supply of water into the tub.
- Results of the wash cycle using the bubbles according to the present invention are shown in FIGS. 5 and 6 .
- FIG. 5 is a graph depicting a shrinkage rate of laundry when washing the laundry in such a way of reducing an amount of water and supplying only bubbles at the same concentration in the same wash cycle.
- "conventional wool washing” indicates a shrinkage rate of wool when a wash cycle is performed at an RPM of 25 and at an operation rate of 1 second-On and 78 seconds-OFF for a washing period of 10 minutes
- "Bubble 1” indicates a shrinkage rate of wool when the wash cycle is performed at an RPM of 25 and at an operation rate of 1 second-On and 78 seconds-OFF for a washing period of 10 minutes as in the conventional wool washing
- "Bubble 2" indicates a shrinkage rate of wool when the wash cycle is performed at an RPM of 25 and at an operation rate of 2 second-On and 78 seconds-OFF for a washing period of 10 minutes, which is different from the conventional wool washing in terms of operation rate.
- Bubble 1 exhibits a noticeably reduced shrinkage rate of the laundry compared with the conventional wool washing
- Bubble 2 exhibits a reduced shrinkage rate of the laundry compared with the conventional wool washing in spite of its higher operation rate than that of the conventional wool washing.
- FIG. 6 is a graph depicting a cleaning degree of contaminated laundry of 60 MU (Make Up) in terms of reflective index at the same amount (2g, 4g, 10g) of detergent, comparing the case of using detergent water with the case of using bubbles, both of which have the same detergent concentration.
- the cleaning degree of the laundry through the wash cycle using the bubbles is noticeably higher than that using the general detergent water.
- FIG. 7 is a detailed flow chart showing a first cycle of the washing machine to remove the bubbles after performing the bubble wash cycle.
- a bubble removing cycle is performed to remove the bubbles remaining in the rotational drum 12 instead of directly performing a rinsing cycle.
- the bubbles are removed by intermittent spin-drying during which the motor 13 is driven at a low RPM (for example, about 400 RPM) (S602).
- a low RPM for example, about 400 RPM
- T1 the minimum time required to remove the bubbles in the rotational drum through the spin-drying
- FIG. 8 is a detailed flow chart showing a second cycle to remove the bubbles after the bubble wash cycle by the washing machine of the present invention.
- the bubble removing cycle is performed to remove the bubbles remaining in the rotational drum 12 instead of directly entering the rinsing cycle.
- the drying heater 44 After draining the water or when blowing air through driving of the drying fan 41 simultaneously with water drainage, the drying heater 44 is driven to supply hot air, thereby removing the bubbles (S612).
- T2 the minimum time required to remove the bubbles in the rotational drum through air or hot air-blowing
- FIG. 9 is a detailed flow chart showing a third cycle to remove the bubbles after the bubble wash cycle by the washing machine.
- the bubble removing cycle is performed to remove the bubbles remaining in the rotational drum 12 instead of directly entering the rinsing cycle.
- the water supply device 20 is controlled to inject a small amount of water in the form of spray between the rotational drum 12 and the tub 11 through the water supply line 26, thereby removing the bubbles (S622).
- T3 the minimum time required to remove the bubbles in the rotational drum through spray injection
- the washing machine and the control method thereof enables laundry to be washed only with bubbles without direct contact with water so that the bubbles act as a cushion to reduce friction between the laundry, thereby preventing texture of expensive laundry (such as wool or silk) from being damaged due to the friction between the laundry and strong water stream, while allowing dirt on the laundry to be effectively removed due to a high detergent concentration on the bubbles.
- the washing machine and the control method thereof according to the present invention uses a small amount of water, thereby enabling reduction in water consumption and energy consumption to heat the water, and preventing damage and deformation of the laundry when washing general laundry.
- the washing machine and the control method thereof according to the invention can generate the bubbles having a predetermined detergent concentration through control of a water supply amount and a detergent input amount upon a bubble washing operation, and can adjust the detergent concentration on the bubbles so as to be suitable to a contaminated degree of the laundry, providing a high cleaning degree not only for a delicate washing operation but also for a general washing operation.
