Description

Washing method}

The present invention relates to the field of washing machines, and more particularly, to a washing control method of a washing machine to obtain a normal washing performance even with very little detergent.

In general, a washing machine is a device that performs washing by a complex action, such as the friction between the water flow and the laundry according to the forced flow of the wash water, the emulsification of the detergent, and the impact action of the laundry wing on the laundry.

Such a conventional washing machine includes a main body 10, a washing outer tub 20, a washing inner tub 30, a washing wing 40, and a driving force transmitting means, as shown in FIG. 1. do.

Here, the laundry outer tub 20 is elastically supported inside the body, the wash water is stored.

The washing inner tub 30 is rotatably mounted at an appropriate interval inside the washing tub 20, and a plurality of through holes 31 are formed on the outer circumferential surface thereof so as to communicate with the inner space of the washing tub 20. do.

In addition, the washing blade 40 is rotatably provided at the center of the inner bottom surface of the washing inner tub (30).

The driving force transmission means includes a clutch 50, a driving motor 60, and a belt 70.

Here, the clutch 50 is fixedly mounted on the bottom surface of the laundry outer tub 20 and is condensed with the washing blade 40 and the washing tub 30, optionally the washing blade 40 or the washing. The inner tub 30 is rotated.

In addition, the drive motor 60 is installed on one side of the outer side bottom of the washing tub 20, and the clutch 50 is provided to enable power transmission.

On the other hand, the upper side of the main body 10 is connected to the water supply hose 12 is supplied with the washing water required for washing, the lower portion of the outer tub 20 is connected to the drain hose 14 for washing the wash water.

Therefore, when the laundry mode is selected in a state in which laundry and a predetermined amount of detergent are put into the washing tub 30, washing, rinsing, and dehydration are automatically performed for a predetermined time according to a control signal of the controller (not shown).

That is, when the washing mode is selected, the water supply valve 11 installed in the water supply hose 12 is opened, and the washing water to be used for washing is supplied into the washing inner tub 30 through the water supply hose 11.

At this time, the washing tub is in communication with the interior of the washing tub 20 by a plurality of through-holes 31 formed along its outer circumferential surface wash water supplied into the washing tub 30 as described above Through each through-hole 31 of the inner tank 30 is introduced into the laundry outer tank 20.

When the wash water is filled in the washing outer tub 20 and the washing inner tub 30 by this process, the water supply valve 11 is closed and no more water is supplied to the outer bottom surface of the washing tub 20. The fixed drive motor 60 drives the clutch 50 while driving in the forward and reverse directions, and the clutch 50 selectively rotates the washing inner tub 30 and the washing blade 40 according to each washing stroke.

Accordingly, the laundry in the washing inner tub 30 is washed by the rotational force of the washing blade 40, the frictional force with the inner circumference of the washing inner tub 30, the decomposition force of the detergent, and the like.

When the washing operation is completed by the above-described action, the drain valve 13 installed in the drain hose 14 opens under the control signal of the controller (not shown), and thus the washing in the outer tub 20 and the washing tub 30 is performed. Washing water that was used in is drained to the outside of the main body 10 through the drain hose (14).

Thereafter, a rinsing stroke is performed in which the new wash water is rinsed several times as the water is supplied into the washing tub 30.

At this time, between each rinsing and rinsing, the dehydration for a short time and the re-supply of new wash water are performed together with the drainage, so that the control is made so that a smoother rinsing is performed.

In addition, after such a rinsing stroke is completed, the final dehydration stroke is performed, and during the final dehydrating stroke, the washing tank 30 and the washing wing 40 are naturally drained to the outside of the washing water used for rinsing. Is rotated at high speed.

Accordingly, while the laundry in the washing tub 30 is pushed outward by the centrifugal force due to the high speed rotation of the washing tub 30 and the washing blade 40, the water contained in the laundry passes through the laundry tub 30 ( 31) through the wash tub 20 is exited.

In this case, since the drain valve 13 installed at the lower portion of the laundry outer tub 20 is opened, the water discharged from the laundry is drained to the outside through the drain hose 14.

The dehydration stroke is performed for a set time, and when the dehydration stroke is completed, all washing processes are completed by completely stopping the operation of the washing machine.

In the conventional method for washing as described above, it is usually necessary to add a certain amount of detergent.

However, the above detergent has a cost burden for its purchase, and has a problem of providing a serious impact on environmental pollution.

In addition, since a large amount of detergent is added, since the rinsing stroke may take a long time, waste water is caused.

Of course, washing may be performed with less detergent than the standard detergent, but under the conventional washing algorithm, if washing with a smaller amount of detergent than the standard amount of detergent described above, a smooth washing performance could not be obtained. I have a problem that causes dissatisfaction.

The present invention has been made in order to solve the above-mentioned conventional problems, it is possible to obtain the washing performance when using a small amount of detergent and a standard amount of detergent to induce the saving of detergent and waste of tap water The purpose is to enable reduction.

The present invention for achieving the above object is a first step of performing a water supply up to about half of the normal water level for the amount of laundry; A second step of performing concentrated washing for an arbitrary first predetermined time by inputting about half the amount of detergent to the normal amount of detergent to the amount of laundry; A third step of additionally supplying water to the normal water level for the amount of laundry after the first predetermined time and performing the main laundry for a second predetermined time; A fourth step of performing a rinsing of the laundry after the second predetermined time; In addition, a washing method for saving the detergent is provided, wherein the fifth step of completely dehydrating the rinsed laundry is performed sequentially.

Hereinafter, with reference to Figures 2 to 4 showing the washing method of the present invention as described above in more detail as follows.

2 is a flowchart illustrating a washing process for saving detergent of the present invention.

That is, the washing method for saving detergent of the present invention includes a control step for initial water supply, a control step for concentrated washing, a control step for main washing, a control step for rinsing, and a control step for final dewatering. It is largely divided.

Here, the control step for the initial water supply is a control process for performing water supply up to about half of the normal water level for the amount of laundry.

When such a control process of the initial water supply is performed, the rotation of the washing tub 30 is performed at the same time to enable smooth wetting of the laundry.

In addition, the detergent is added during the initial water supply, wherein the amount of detergent added is about half of the normal amount of detergent added to the amount of laundry.

In addition, the control step for the concentrated washing is to wash the laundry with a relatively small amount of washing water in which detergent is concentrated while at least one or more of the washing inner tub 30 and the washing blade 40 is inverted left and right with the addition of the detergent. This is a control process for washing the main contaminants to be washed.

At this time, the washing time for the concentrated washing is set to about 10 minutes.

The control step for the present washing is a control process of washing the laundry by additionally supplying water to the normal water level of the laundry after the concentrated washing, and is a process for removing various contaminants or lint between the clothes. .

In this case, the laundry is washed at least one or more of the washing tub 30 and the washing blade 40 in the same way as the above-described concentrated washing.

In addition, the present washing is set to be performed shorter than the washing time for the above-described concentrated washing, the present invention suggests that the washing time of the main washing is set to about 5 minutes.

And, the rinsing step is a control process for removing the dissolved detergent from the laundry in which the main washing is completed.

At this time, the rinsing step is performed through the left and right inversion and stirring of the washing inner tub 30 and the washing wing 40.

And, the control step for the final dehydration is a control process to end the washing by finally dehydrating the rinsed finished laundry.

At this time, the rotational speed of the washing tub for the final dewatering can be made to the maximum RPM to enable a smooth dehydration progress.

Hereinafter, with reference to Figures 2 to 4 showing a washing process using the washing method of the present invention as described above in detail as follows.

First, if the user selects a washing course for saving detergent (hereinafter, referred to as “detergent saving course”) (S101), the controller for controlling the operation of the washing machine (not shown) may determine the weight of the laundry. The measurement confirms the amount of laundry and determines the normal water level and the amount of detergent added.

At this time, the determination of the water supply level according to the amount of laundry is a generally known process.

If the user performs the selection of the course using the standard detergent, the controller performs the operation with the existing standard washing course (S102).

When the determination of the water supply level is made, the controller controls various control valves, for example, a water supply valve, to perform water supply to the inside of the washing tub 30 only about half of the determined water supply level.

At this time, the controller rotates the washing tub 30 by controlling the driving motor so that the laundry is sufficiently wetted in the washing water.

In addition, while washing the main contaminants of the laundry by performing the concentrated washing for a predetermined first time by inputting about half of the normal amount of detergent to the amount of the laundry while the above process is performed (S104). .

At this time, the predetermined first predetermined time is about 10 minutes as described above.

When the concentrated washing for the first set period is completed, the washing water as much as the normal water supply level is additionally supplied into the washing tub 30 (S105).

In the process, the concentrated wash water is gradually diluted with fresh water which is additionally watered, and contaminants are removed from the laundry together with the detergent dissolved in the laundry.

When the additional water supply is completed, the main washing is performed again during the second set time (S106).

In this case, the second set time may be about 5 minutes. The reason for performing the main washing shorter than the concentrated washing is that the laundry washed by the concentrated washing water is recontaminated due to the contaminants that were previously removed. This is to prevent the phenomenon.

In particular, while the present washing is performed, the remaining contaminants stuck between the laundry are discharged and lint is removed.

After the second predetermined time passes, the washing water contaminated by washing is drained by performing the draining process.

Thereafter, new washing water for rinsing is supplied to the washing tub 30, and then rinsing is performed (S107).

At this time, the water supply level for the rinsing may be approximately the normal water level for the amount of the laundry to increase the rinsing efficiency, the rinsing by performing a light dehydration before the water supply of the wash water for the rinsing More preferably, the efficiency can be further increased.

In addition, the rinsing process is similar to the washing process, but a process for rinsing for a relatively short time with washing water that does not contain detergent to completely remove the detergent remaining in the laundry and to complete the washing. to be.

When the rinsing is completed, the washing water used to rinse is drained, and the washing tank 30 is driven at the maximum rotation speed to completely dehydrate the laundry (S108).

As described above, if washing is performed through the washing process according to the embodiment of the present invention, it is possible to obtain approximately the same washing efficiency as the conventional standard washing, which can be clearly seen through the graph of FIG. 4.

At this time, in the above graph, when the laundry is performed at a low water level with a small amount of laundry, when the laundry is performed at an appropriate medium water level, and when the laundry is performed at a high water level due to a large amount of the laundry. The experimental values are shown for each.

As described above, the washing method of the present invention can achieve the same effect as the laundry performance when a small amount of detergent is used even when a standard amount of detergent is used, thereby inducing detergent savings and wasting tap water. Has the effect of being able to reduce.
