The present invention relates to a washing machine, and more particularly, to a well-being course control method of a washing machine for suggesting a washing-style washing algorithm that is more suitable for the health culture pursued by a user.

In general, a washing machine is a household appliance most commonly used in homes, and is attached to laundry of clothes and bedding by using an emulsifying action of a detergent, a friction action of washing water caused by a rotary motion, and an impact effect on the laundry. It is a device that cleans contaminants cleanly.

In general, a washing machine used in the home has come out of a variety of products, such as vortex type, stirring type, drum type, in particular, the drum type structure is used a lot for business purposes. In addition, there are separate and fully automatic washing and dewatering tanks.                         

In the separate type, the washing tank and the dehydration tank are separated, and in the washing tank, the rotary vanes at the bottom cause waves to change back and forth, washing and rinsing, and the dehydrating tank is dehydrated by dispersing water with a high-speed rotating centrifugal force.

On the other hand, in the fully automatic type, the cylinders are doublely stacked. The laundry is washed and rinsed by rotating the rotating pulsator on the floor, and when dewatering, the inner cylinder with a lot of holes is rotated at a high speed to dewater.

Recently, the performance has been advanced to the 'inverter' or 'direct drive (DD) method', and the like, and in particular, the fuzzy control method adjusts the operation time by determining conditions such as the amount of laundry and the degree of contamination each time.

In general, the washing administration is a process of removing contaminants on laundry by putting detergent, washing water and objects to be washed and stirring washing blades for a predetermined time by chemical action of detergent contained in washing water and physical action of washing blades. .

In addition, the rinsing stroke is a process of supplying the washing water not mixed with the detergent to rinse the detergent components and contaminants in the laundry cleanly, and the dehydration stroke is performed on the laundry object while rotating the washing tank at a high speed after the rinsing stroke is finished. It is the process of dehydrating the moisture contained.

Most washing machines have a number of washing course programs in memory to properly set the washing time, rinsing time, and dehydration time according to the cloth or amount of laundry to prevent damage to the cloth of the laundry and to perform clean washing. It is stored in advance.                         

For example, various washing course programs such as centrifugal washing, highly concentrated washing, vibrating washing, soaking washing, wool washing, etc. are stored in the memory of the washing machine so that the user can easily select and select an arbitrary washing course program to execute automatic washing. I can do it.

However, with the recent improvement in living standards, the so-called well-being culture has begun to spread, and the demand for a new lifestyle related to health is only growing.

Due to these cultural changes, if detergent or bacteria remain in the washed clothes, it not only damages the skin health but also prevents user discomfort.

In other words, the existing washing algorithm alone did not satisfy the healthy life code that the user intended.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a well-being course control method of a washing machine that can further improve the effect of removing detergent or miso (汚垢).

Another object of the present invention is to provide a well-being course control method of a washing machine that can be used with confidence for the user's skin health.

In order to achieve the above object, the present invention comprises the steps of performing a preliminary washing stroke for driving the drum in a prewash cycle having a first drive speed for a predetermined time; When the preliminary washing operation is completed, draining water in the drum to dewater at a first dehydration speed; Performing a main washing stroke for driving the drum in a main washing cycle having a second driving speed for a predetermined time while driving the heater to a preset set water temperature; Draining water in the drum to dehydrate at a first dehydration rate when the main washing process is completed; Performing a rinsing stroke for driving the drum in a rinsing cycle having a second rinsing time with a rinsing time / water level per rinsing frequency / time greater than a standard course; Dewatering at a second dehydration rate by draining water in the drum each time the rinsing stroke is completed; And, when the rinsing step is completed provides a well-being course control method of the washing machine comprising the step of performing a dehydration stroke for driving the drum in a dehydration cycle having a third dehydration speed.

Here, the pre-washing cycle, the main washing cycle and the dehydration cycle is preferably composed of a drum drive section and a drum stop section.

In addition, a detergent container 15 is installed on the inner upper side of the outer case 1 so as to inject detergent required for washing, and a detergent container through the water supply hose 13 on one side of the detergent container 15 and the outer tub 5. A water supply bellows 17 is provided to supply water into which the detergent is dissolved and the detergent dissolved therein into the outer tub 5, and at the same time, expand and contract with the outer tub 5.

One side of the outer tub 5 is provided with a motor 19 to generate power, and one side of the motor 19 transmits rotational force of the motor 19 to forward / reverse rotation of the inner tub 7. The belt 21 and the pulley 23 are provided so that it may be made.

The drainage bellows 25 is installed at the lower side of the outer tub to discharge the contaminated washing water after the washing process, and one side of the drainage bellows 25 is configured to pump the drained water through the drainage bellows 25. 27 is installed, and the drain hose 29 is installed at one side of the drain pump 27 to discharge the water pumped through the drain pump 27 to the outside.

The inner side of the outer case (1) is provided with a water level sensor 31 to detect the water level through the water pressure to determine whether or not the water supplied to the water tank 5, the outer tank (5) The water level sensor hose 33 for transmitting the water pressure inside the water level sensor 31 is installed, and the water contained in the outer tank 5 is prevented from leaking between the outer tank 5 and the door 3. The gasket 35 is provided.

The heater 41 is installed between the lower part of the outer tank 5 and the inner tank 7 to provide a heat source during the boiling process, and when the temperature inside the outer tank 5 increases due to the heater 41, The water temperature sensor 43 for transmitting the detection result to the system microcomputer (not shown) is installed.

Referring to Figure 2, the embodiment of the well-being course washing method of the present invention using the drum washing machine of the above configuration will be described in detail as follows.

The user selects a 'well-being course' among a plurality of washing courses through a function operation unit (that is, a user input means) (not shown) installed in the out case 1 (S10).

When the command of 'wellness course' execution is input from the user, the washing water is supplied into the drum together with the detergent. When water is supplied to the preset pre-washing level, the water is stopped and the preliminary washing administration is performed (S12).

In this case, when the preliminary washing operation is started, the drum is rotated at the first driving speed V1 for a predetermined time and the drum stop operation is repeated, and the washing time is previously called or removed.

After the preliminary washing operation is completed, the washing water in the drum is drained and intermittent dehydration is performed at a first dehydration speed V11 for a predetermined time (S14).

Subsequently, after the water is supplied to the main washing level for the main washing operation, the drum is rotated forward or reverse at a second driving speed V2 greater than the first driving speed V1 for a predetermined time, and at the same time, the heater 41 ).

In other words, the main washing stroke is a full-scale washing stroke to remove contaminants from the laundry by the chemical action of the detergent contained in the wash water and the physical action of the drum. By rotating the laundry to remove the dirt (S16).

In particular, the main washing stroke is a stroke using hot water to drive the heater 41, thereby improving the decomposition ability of the contaminants by driving the heater 41 to the first snow purification temperature (T1) (for example, 40 ℃). Bio course for driving and to drive the heater 41 to the second set water temperature (T2) (for example 70 ℃ ~ 90 ℃) higher than the bio stroke for eradicating bacteria contained in the laundry Boiling Course

In other words, the bio-administration time and the boil-off time are appropriately set to perform the main washing process.

Here, the first set water temperature (T1) is the temperature at which the enzyme is best dissolved, and the second set water temperature (T2) is a temperature at which the bactericidal effect is high without damaging the cloth, the best temperature level through repeated simulations Set.

The reason why the hot water is used by driving the heater 41 in the main washing process is to increase the decomposability of the five holes and the detergent and to easily remove the residual amount by the thermal action by the hot water.

When the washing operation is performed using warm water, bubbles are expanded between the fibers of the laundry and there is an advantage that the remaining amount of the detergent and the wrong tool is more easily released from the laundry by a predetermined mechanical force while the bubbles of the fibers themselves expand.

When the main washing stroke consisting of the bio-stroke and the boil-off stroke is completed, the dirty laundry water is drained by the washing stroke and intermittent dehydration is performed at the first dehydration speed V11 for a predetermined time (S18).

Subsequently, the washing water not mixed with the detergent is supplied to a predetermined rinsing water level to perform a rinsing stroke to rinse clean the detergent components and contaminants contained in the laundry (S20).

In this case, the rinsing stroke of the present invention sets the rinsing water level, the number of rinsing times, and the rinsing time per stroke to be relatively larger than a normal course.

For example, if the number of rinses is three times in the standard course and the rinsing time is three minutes, the wellness course performs a rinse stroke with four rinses and a rinse time every five minutes. In addition, the rinse level is also set larger than 0.3㎑ compared to the standard course.

That is, during the rinsing stroke, the rinsing water level, the rinsing frequency, and the rinsing time per time are set larger than those of the standard course so that the detergent or contaminants are sufficiently removed from the laundry.

Then, every time the rinsing cycle is finished, intermittent dehydration is performed at a second dehydration speed V12 after draining in order to drain the wash water in the drum and resupply cleaner wash water (S22, S24, and S26).

At this time, the dehydration speed (V12) of the intermittent dehydration during the rinsing stroke is increased to the rotational speed (rpm) (that is, the third dehydration speed (V13)) during the main dehydration stroke to remove the detergent or contaminants contained in the laundry to the maximum. Make it out.

That is, by setting the speed of the intermittent dehydration made in the middle of the rinsing stroke relatively large, it is possible to increase the removal effect of detergent and miso by minimizing the degree of contamination of the rewatered wash water.

Subsequently, when the rinsing stroke is completed by repeating the above-described number of rinsing cycles, the drum is rapidly rotated at a third dehydration speed V13 for a predetermined time to perform a full-scale dehydration stroke to remove water from laundry (S28).                     

Therefore, the present invention provides a well-being course that can increase the effect of removing detergents and false positives for the user's skin health.

The present invention is not limited to the above-described embodiments, and can be modified by those skilled in the art as can be seen from the appended claims, and such modifications are within the scope of the present invention.

The well-being course control method of the washing machine according to the present invention described above can provide a well-being course excellent in the removal effect of detergent or miso, the user can use with confidence for skin health. Therefore, there is an effect that can further increase the user's product satisfaction and reliability.
