As shown in FIG. 2, the washing machine according to the exemplary embodiment of the present invention has each drive unit 63-67 for driving various devices in addition to the devices shown in FIG. 1, so that a user can manually input an operation command. It stores the input unit 62, the input amount of detergent solution according to the weight or type of laundry (hereinafter simply referred to as water supply amount), foaming time (time for making bubbles in the bubble generator 50), etc. Memory 61, and a control unit 60 for controlling the devices of the washing machine.

The input unit 62 is provided with buttons and other buttons on which various kinds of laundry are displayed so that a user may input the type of laundry (or a washing course type).

The memory 61 stores detergent dissolution solution input amount and foaming time data that vary depending on the weight of laundry. The reason why the amount of detergent solution is adjusted according to the weight of the laundry is that the appropriate amount of foam to be supplied to the laundry varies when the weight of the laundry changes, and the manufacturer of the washing machine experiments with the detergent in consideration of the capacity of the water tank 11. The solution input and foaming time can be determined.

The above-mentioned facts apply equally even if the type of laundry is different, and in this embodiment, the detergent dissolution solution input amount and the foaming time data considering the weight and type of the laundry for convenience are illustrated (see FIG. 3).

3, it can be seen that the detergent dissolution solution input amount (ie, water supply amount) depends on the weight and type of laundry. In other words, as the weight of laundry increases, the amount of foam required for washing increases, so that the amount of detergent solution used to generate foam increases.

The amount of detergent solution supplied may vary depending on the type of laundry even if the weight of the laundry is the same. This is because even if the laundry of the same weight, if the material of the laundry is different, the amount of foam to be supplied is also different because the ease of penetration of the foam is different.

In this embodiment, the initial water supply amount is changed to change the detergent dissolution liquid input amount (that is, the water supply amount), or when the additional water supply is required, the additional water supply amount and the additional water supply frequency are different.

As described above, the additional water supply or the additional water supply a plurality of times in this embodiment requires a large amount of laundry or a large amount of laundry due to the material properties of the laundry. Because there are times. In addition, depending on the situation, even if some washing effect can be obtained by the initial water supply, additional water supply may be considered in order to increase the washing effect.

On the other hand, if the weight or type of laundry put in the washing tank is different, the amount of foam required as described above is also different, not only the amount of detergent dissolution solution is changed, the foaming time is also adjusted differently. In other words, laundry that requires a lot of foam generates bubbles for a sufficient time, so that a large amount of foam can be supplied to the laundry. In the case where a relatively small amount of foam is required, the foaming time is reduced and the washing time is unnecessarily longer. It is desirable to avoid.

Hereinafter, a foam washing method of the washing machine according to an embodiment of the present invention will be described with reference to FIGS. 4 and 5. When the user puts laundry into the washing machine, puts the detergent into the detergent storage box 21, inputs the type of laundry using the input unit 62, and then presses an operation button (not shown), the controller 60 controls the type of laundry. Check and, by rotating the washing tank 12 detects the weight of the laundry (100).

When the weight of the laundry and the type of the laundry are confirmed, the control unit 60 finds each water supply amount, additional water supply time and foaming time corresponding to the identified laundry weight and laundry type in the table as shown in FIG. 3 stored in the memory 61. (110). Then, the water supply valve 24 is opened, and the three-way valve 23 is opened toward the detergent storage box 21 to supply the detergent solution to the water tank 11 as much as the initial water supply amount (120).

When the initial water supply is completed, the controller 60 generates bubbles by operating the bubble generator 50 (130). At the time of foam generation, the foam generator 50 is turned on in a state in which the washing tank 12 is stopped (131). Then, the water level sensor 17 measures the water level of the water tank 11 to determine whether the level of the detergent solution is lower than the boundary level (132).

If the level of the detergent solution is lower than the boundary level, the process proceeds to step 140. If the level of the detergent solution is not lower than the boundary level, it is determined whether the foaming time has elapsed (133). In this case, the boundary water level means a level at which the generation of bubbles is difficult due to lack of detergent solution even when the bubble generator 50 is operated, and the boundary water level is preferably set by an experiment.

If the foaming time has not elapsed, the process returns to step 132. If the foaming time has elapsed, the foaming device 50 is turned off, and the washing tank 12 is rotated to mix the foam and the laundry well (134,135). ).

Next, the control unit 60 checks whether the additional water supply is needed (140), if no additional water supply is required, and proceeds to step 170, and if the additional water supply is necessary, determines whether the additional water supply number is the set number of times (150). Although FIG. 3 illustrates that additional water is supplied even if the weight of the laundry is small for convenience, when the laundry is less, the data may be set to wash the foam only with the initial water supply. Therefore, it is determined whether additional water is needed in step 140.

If the additional water supply frequency does not satisfy the set number of times, the controller 60 opens the water supply valve 24 again, adjusts the three-way valve 23 direction to the detergent storage box 21, and performs additional water supply (160). Generates 130.

On the contrary, if the additional water is set, the control unit rotates the washing tank 12. Since the washing tank rotation of step 135 is a rotation for mixing laundry and foam, the rotation speed of the washing tank 12 is relatively slow, but the washing tank of this step is The rotation is a rotation for washing the laundry by the friction between the laundry after mixing the laundry and the foam enough to relatively increase the rotation speed.

Next, the controller 60 performs a rinsing and dehydration stroke (180).

In the present embodiment, each water supply amount and foaming time are differently illustrated in consideration of the weight and type of laundry, but each water supply amount and foaming time is determined only by considering the weight of the laundry, or each water supply amount and foam is only considered in consideration of the type of laundry. You can also specify the creation time.

As described in detail above, the present invention can wash the laundry with only foam, can be washed with a small amount of washing water, less damage to the laundry.

In addition, the present invention is to adjust the amount of foam generated according to the weight or type of laundry so that the optimum foam washing regardless of the weight or type of laundry.
