The present invention relates to a method of operating a washing machine, and more particularly, to a new operation method capable of sterilizing a laundry after washing, while enabling a sump of laundry with a small amount of washing water consumption and low power consumption.

Generally, a washing machine is classified into a pulsator washing machine in which a drum is set in a vertical direction, and a drum washing machine in which the drum is laid in a horizontal direction.

Here, since the drum washing machine is laid down in the horizontal direction as described above, the drum washing machine performs washing by dropping the laundry introduced into the drum.

1 and 2 schematically show a conventional structure of the aforementioned drum washing machine.

That is, the drum washing machine includes a main body 10, an out tub 20 mounted in the main body 10, a drum 30 rotatably mounted in the out tub 20, and the drum 30. It is configured to include a driving means for driving.

Here, an inlet 11 through which laundry is introduced is formed on the front surface of the main body 10, and a door 40 that opens and closes the inlet is mounted at a peripheral portion of the inlet 11.

In addition, a rim 50 for sealing between the door 40 and the inlet 11 is mounted on the inner circumference of the inlet 11.

In addition, the outer tub 20 is provided with dampers 21 at both bottoms of the outer circumferential surface thereof to form a state of being supported in the main body 10.

In addition, the driving means comprises a drive motor 71 for driving the drum 30, and a belt 72 connected to transfer the driving force of the drive motor 71 to the drum 30.

However, the conventional washing machine as described above not only consumes a lot of washing water unnecessarily even when washing a small amount of laundry and washing the laundry with a low contamination level, but also the process is performed at about the same time as the general washing process. Since it is made, the consumption of electricity is unnecessarily large.

In particular, performing the soaking process before washing is more effective in washing performance, but since the consumption of the washing water for the soaking process is considerably large, the soaking process is omitted in the normal washing process, thereby obtaining the best washing performance. It has a number of problems.

In addition, in the conventional washing process, there is no separate process for sterilizing laundry.

Of course, although not shown in recent years, a separate washing water heater for heating the washing water is also provided in the washing machine so that it can be boiled laundry structure, but since the sterilization of the laundry was made only by the boiling stroke is required for the boil administration Due to the increased washing water and power consumption is not preferred.

Therefore, there is a need for a new stroke that can sterilize laundry even with a small amount of wash water and low power consumption.

The present invention has been made to solve the above-mentioned various problems with the prior art, the object of the present invention is to enable the soaking of the laundry with a small amount of washing water consumption and low power consumption and sterilization of the laundry after washing It is an object of the present invention to provide a laundry apparatus having a new structure and a driving method using the same.

In order to achieve the above object, the present invention provides a method of operating a washing machine having at least one steam dispensing apparatus for providing a predetermined amount of steam into the drum, by operating the steam dissipating apparatus to dissipate steam into the drum into which the laundry is put Steam providing step; Washing water supplying step of supplying the washing water according to the amount of laundry to the drum in which the laundry is put; Washing step of performing the washing by rotating the drum for a set time; A rinsing step of performing at least one rinsing upon completion of the washing; In addition, a dehydration step of performing a final dehydration stroke upon completion of the rinsing is provided.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 3 to 5 showing preferred embodiments of the above-described embodiments of the present invention and preferred embodiments of the driving method of the present invention.

First, the washing machine according to an embodiment of the present invention includes a main body 110, an outer tub 120, a drum 130, and a steam dissipation device as shown in FIG. It is set as an Example.

At this time, the main body 110 forms an appearance of the drum washing machine, and the outer tub 120 is provided in a state of being supported in the main body 110.                     

The drum 130 is rotatably installed in the outer tub 120, and is mounted such that a side opened toward the inlet 111 of the main body 110 is positioned.

At this time, the door 140 for opening and closing the inlet 111 is mounted to a portion where the inlet 111 of the main body 110 is formed, and the door 140 and the inner circumferential surface of the inlet 111. Rim 150 for sealing between the inlet 111 is mounted.

In addition, a plurality of through holes 131 are formed on the circumferential surface of the drum 130 so that washing water and steam can be introduced into the drum 130.

In addition, the steam dissipation device is configured to provide a predetermined amount of steam into the drum 130, at least one is provided.

The steam dissipation device is installed to vaporize the water with high temperature heat to provide it into the drum 130, and by the heat generating unit 210 and the heat generating unit 210 to provide high temperature heat to vaporize the water. It is configured to include a steam supply pipe 220 through which the flow of steam is steamed.

In addition, the steam diverging device further comprises a spray nozzle 230 for discharging steam flowing through the steam supply pipe 220 into the drum 130.

At this time, the injection nozzle 230 is configured in the shape of a nozzle (nozzle) to enable a smooth divergence of steam, the end of the discharge of steam is preferably installed to face the drum 130.

Of course, as shown in Figure 4 attached to the end of the injection nozzle 230 in which the discharge of steam is made may be configured to only communicate with the inside of the outer tub 120, in this case, the steam directly into the laundry in the drum (130) It is not preferred because it is not sprayed.

In particular, the steam dissipation device should be configured to enable the divergence of the selective steam, for this purpose further comprises an on-off valve 221 for opening and closing of the pipeline on the pipeline of the steam supply pipe 220 Yes.

Hereinafter, a driving method according to an embodiment of the present invention for performing a washing stroke with the structure of the washing machine described above will be described with reference to the flowchart of FIG. 5.

First, the controller (not shown) controlling the operation of the washing machine continuously checks generation of a request for executing a washing operation by a user (S110).

If the user selects to perform the operation of the washing machine while the laundry is put in the drum 130, the controller operates the steam diverging device to generate steam and also generates the steam inside the drum 130. Control to diverge to (S120).

At this time, the generation of the steam is generated by the evaporation of the water supplied to the steam dissipating device by the heat of the heat generating unit 210 forming the steam dissipating device, the generated steam is guided by the steam supply pipe 220 After receiving and flowing, it is emitted into the drum 130 through the injection nozzle 230.

Steam dissipated into the drum 130 as described above is generated by the heat generated by the heat generating unit 210 to achieve a high temperature (temperature enough to sterilize bacteria, etc.), thereby causing the laundry in the drum 130 Sterilization takes place.

In particular, the process of providing the steam is controlled to be continuously performed for a time enough to be called for the laundry in the drum (130).

This is desirable if the steam is not enough to affect the laundry if performed only for a short time, so that the soak may not be made so that it lasts for a time until a sufficient soak is made.

However, if the steam is provided for too long time, the water consumption and power consumption can be increased compared to the soaking effect, it is more preferable that the steam providing process is set shorter than the time for the washing stroke.

In this case, the washing of the laundry may be performed by the steam because the steam is at a high temperature and at the same time, since the steam is composed of a large amount of water, various contaminants are smoothly separated from the laundry affected by the steam. to be.

As a result, the laundry in the drum is substantially called by providing the steam for a predetermined time.

Then, when the process of providing the steam is completed, the controller controls to stop the operation of the steam dissipating device (S130) and supplies the appropriate amount of washing water into the drum 130 for the actual washing (S140).

At this time, the appropriate amount of the washing water supplied into the drum 130 is a predetermined amount according to the amount of laundry.

In the process of supplying the wash water, it is preferable to supply an appropriate amount of detergent.

Of course, the detergent may be supplied to the drum 130 at the same time as the steam is provided, because the steam can activate the detergent penetrated into the laundry to facilitate the separation of contaminants.

When the supply of the washing water is completed, the drum 130 is rotated for a set time (S150).

In other words, by forcibly flowing the wash water is to separate the washing time in the laundry by the complex action, such as the friction between the water flow and the laundry, the emulsification of the detergent to perform the washing.

At this time, the rotation direction, the rotational speed, the stroke progress time, etc. of the drum 130 for the washing stroke is preferably the same as the conventional washing stroke.

In addition, when the washing is completed, at least one rinse is performed (S160).

At this time, when the rinse cycle is a plurality of times, drainage, dehydration, rewatering, and the like are repeatedly performed.

Then, when the above-described rinsing process is completed, the washing is completed by performing a final dehydration stroke (S170).

On the other hand, in the embodiment of the present invention, after the final dehydration stroke is completed by operating the steam dissipating device further includes a final steam providing step (S180) for discharging steam back into the drum 130, the laundry is put therein It features.

At this time, the steam is preferably provided at a temperature higher than the temperature at which the laundry can be sterilized, for example, 60 ° C. (preferably 70 ° C.) or higher, and the time for providing the steam is such that the refresh of the laundry in the drum is completed. It is desirable to only perform for a time that can be achieved.

In particular, as described above, the amount of steam sprayed into the drum 130 may be set so that the amount may be minute enough to not wet the laundry.

That is, the final steam providing step is to perform the refreshing action and sterilization action of the laundry rather than inducing the same action as the soaking of the laundry by the first steam supply.

As a result, the whole washing is finished by the completion of the above-described final steam providing step.

As described above, the operating method of the washing machine according to the embodiment of the present invention is to improve the overall washing performance because the washing of the laundry in the drum is performed through a small amount of water and power consumption before the actual washing is performed. Can have the effect.

In addition, by providing a high-temperature steam again to the laundry in the drum after the washing is completed for a short time, it is possible to refresh and sterilize the laundry has an effect that the user's satisfaction with the washing performance can be improved.
