Description:FIELD OF THE DISCLOSURE

The present disclosure relates to washing machines, and particularly, the present disclosure relates to a washing machine for washing laundry and a method thereof.

BACKGROUND

Generally, washing machines include a drum with a pulsator. Further, the drum and the pulsator spin independently to wash laundry accommodated in the drum. An existing method of washing laundry in an existing washing machine includes supplying water and initiating the washing cycle of the washing machine. The target amount of water to be supplied is determined based on the amount of the load of the laundry in the washing machine. Herein, the total volume of target amount of water is supplied to the washing machine at the initial stage of washing, such that the total volume of water is utilized during the whole washing cycle.

However, the existing method of washing laundry results in consumption of more water, as the total volume of water is required during the whole washing cycle. Further, in the existing method of washing laundry, the drum spins along with the pulsator that results in the tangling of the laundry during the washing cycle. This may impact washing performance of the washing machine as the tangled laundry is received after the washing. Also, the spinning of the drum along with the pulsator consumes more energy, which increases an overall cost associated with the operation of the washing machine.

Therefore, in view of the above-mentioned problems, there lies a need to provide a washing machine and/or a method for washing laundry that can eliminate one or more above-mentioned problems associated with the existing washing machines.

SUMMARY

This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the disclosure. This summary is neither intended to identify key or essential inventive concepts of the disclosure nor is intended for determining the scope of the disclosure.

The present disclosure discloses a method for washing laundry in a drum having a pulsator adapted to spin for a predetermined time period. The method may include actuating the drum and the pulsator to spin in a first predefined ratio in a first phase of the washing. Further, the method may include actuating the drum and the pulsator to spin in a second predefined ratio for at least one cycle in a second phase of the washing. Moreover, the method may include actuating the drum and the pulsator to spin in a third predefined ratio in a third phase of the washing. An available time period for the second phase is a time available after allotment of a time period for each of the first phase and the third phase from the predetermined time, and at least one cycle is determined based on the available time period.

In another embodiment, a washing machine for multi-phase washing of laundry is disclosed herein. The machine may include a drum and a pulsator. The drum defines a hollow portion adapted to accommodate the laundry to be washed. The pulsator may be at least partially positioned in the drum. Each of the drum and the pulsator are adapted to spin in at least one of a first predefined ratio in a first phase of washing of laundry, a second predefined ratio in a second phase of the washing of laundry, and a third predefined ratio in a third phase of the washing of laundry.

The washing machine, and the method of washing the laundry may facilitate the spinning of the drum and the pulsator in the specific ratios in accordance with the respective phases. This reduces the tangling of the laundry, thereby resulting in a tangle free washing of laundry. Further the spinning of the drum and the pulsator in the specific ratios may reduce the consumption of energy required to operate the washing machine.

The first predefined ratio 302-1, the second predefined ratio 304-1, and the third predefined ratio 306-1 may vary based on the weight of laundry 112 to be washed.

Figure 4 illustrates a graph depicting different levels of water in the washing machine 100, according to an embodiment of the present disclosure. Figures 5(a), 5(b), and 5(c) illustrate schematic views of the washing machine 100 having different levels of water, according to an embodiment of the present disclosure. Referring to Figures 4, 5(a), 5(b), and 5(c), the controlling unit 110 may be configured to fill different volumes of the target water to the washing machine 100 in the respective phase. In the illustrated embodiment as shown in Figure 5(a), a first volume of the water may be filled in the washing machine 100, in the first phase 302 to mix the detergent with the water. The first volume of the water may be equal to a first percentile of the total volume of water. Herein, the first percentile may be in a range of 70 to 75% of the total volume of the water, without departing from the scope of the present disclosure. This makes a concentrated detergent solution with minimum amount of water that effectively activates detergent to remove dirt particles.

In the illustrated embodiment as shown in Figure 5(b), a second volume of the water may be filled in the washing machine 100, in the second phase 304 to wash the laundry 112 with the mixture of the water and the detergent. The second volume may be added to the first volume already filled in the washing machine 100, and the addition of the first volume and the second volume may be equal to a second percentile of the total volume. Herein, the second percentile may be in the range of 90 to 95% of the total volume of the water, without departing from the scope of the present disclosure. The addition of the second volume of water may create more powerful water whirls that loosen dirt particles from laundry 112.

In the illustrated embodiment as shown in Figure 5(c), a third volume of the water may be filled in the washing machine 100, in the third phase 306 to remove the detergent from the laundry 112. The third volume may be added to the first volume and the second volume already filled in the washing machine 100, and the addition of the first volume, the second volume, and the third volume may be equal to a third percentile of the total volume. Herein, the third percentile may be considered as 100% of the total volume of the water, without departing from the scope of the present disclosure. The addition of the third volume of water may thoroughly penetrate each fiber to effectively separate dirt particles from the laundry 112.

Herein, 70 to 75% of the total volume of the water may be used in the first phase 302, 90 to 95% of the total volume of the water may be used in the second phase 304, and 100% of the total volume of the water may be used in the third phase 306. Thus, there is no need to maintain 100% of water during all three phases of the washing, such that the consumption of water in the washing laundry 112 is significantly reduced. Further, the amount of the detergent is also reduced based on the reduction in the consumption of water.

The present disclosure also relates to a method 600 for washing laundry 112 in the drum 104 having the pulsator 106 adapted to spin for a predetermined time period as shown in Figure 6. The order in which the method steps are described below is not intended to be construed as a limitation, and any number of the described method steps can be combined in any appropriate order to execute the method 600 or an alternative method. Additionally, individual steps may be deleted from the method 600 without departing from the spirit and scope of the subject matter described herein.

The method 600 for washing laundry 112 may be performed by using the washing machine 100 as shown at least in Figure 1. The method begins at step 602, which includes actuating the drum 104 and the pulsator 106 to spin in the first predefined ratio 302-1 in the first phase 302 of the washing. The drum 104 and the pulsator 106 may be actuated by the controlling unit 110 to spin in the first predefined ratio 302-1 in the first phase 302 to mix the detergent with the water. The first predefined ratio 302-1 may be 3:1, without departing from the scope of the present disclosure.

At next step 604, the method 600 includes actuating the drum 104 and the pulsator 106 to spin in the second predefined ratio 304-1 in the second phase 304 of the washing. The drum 104 and the pulsator 106 may be actuated by the controlling unit 110 to spin in the second predefined ratio 304-1 in the second phase 304 to wash the laundry 112 with the mixture of the detergent with the water. The second predefined ratio 304-1 may be 4:1, without departing from the scope of the present disclosure.

At next step 606, the method 600 includes actuating the drum 104 and the pulsator 106 to spin in the third predefined ratio 306-1 in the third phase 306 of the washing. The drum 104 and the pulsator 106 may be actuated by the controlling unit 110 to spin in the third predefined ratio 306-1 in the third phase 306 to remove the detergent from the laundry 112. The third predefined ratio 306-1 may be 2:1, without departing from the scope of the present disclosure.

In one embodiment, the washing machine 100 and the method 600 of present disclosure may facilitate the spinning of the drum 104 and the pulsator 106 in the specific ratios in accordance with the respective phases. This reduces the tangling of the laundry 112 which results in tangle free washing of laundry 112. The implementation of the washing machine 100 and the method 600 may also reduce the consumption of energy required to operate the washing machine 100, as the drum 104 and the pulsator 106 may spin in the specific ratios. Further, the washing of the laundry 112 may be performed by filling 70 to 75% of the total volume of the water in the first phase 302, 90 to 95% of the total volume of the water in the second phase 304, and 100% of the total volume of the water in the third phase 306, without maintaining the 100% of water during all three phases of the washing. Thus, the method of washing laundry 112 may also reduce the consumption of water in the washing laundry 112. The reduction in the consumption of water may also reduce the amount of the detergent required for washing the laundry 112. Moreover, the overall performance of the washing machine 100 is also improved, as the laundry 112 caring is enhanced, and the mixing of detergent with water is improved.

While specific language has been used to describe the present disclosure, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. , Claims:WE CLAIM:
