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 includes a drive motor 71 for driving the drum 30 and a belt 72 connected to the belt pulley 73 to transfer the driving force of the drive motor 71 to the drum 30. It is configured by.

Therefore, when a general washing request by the user is made, a controller (not shown) for controlling the operation performs washing for laundry while sequentially performing a washing stroke, a rinsing stroke, and a final dewatering stroke.

At this time, in the washing stroke, the contaminants are separated by friction between the laundry and the drum 30 due to the separation of the contaminants by the detergent and the continuous rotation of the drum 30.

In addition, in the rinsing stroke, the process of rinsing the remaining detergent and contaminants generated during the washing stroke through the supply of new wash water and the repeated rotation of the drum 30 is rinsed.

In the final dehydration stroke, the drum 30 is rotated at a high speed (approximately 800 RPM to 1300 RPM) to remove water from the rinsed laundry.

However, the above-described conventional washing machine and washing method using the same have various problems described below.

First, the conventional washing machine and washing method has a problem that a considerable amount of washing water and electricity consumption are required for the washing stroke and the rinsing stroke.

Secondly, the conventional washing machine and washing method have a problem in that a large amount of washing water is consumed as well as the consumption of electricity for the above-mentioned process is considerably large because the rinsing stroke has to repeatedly provide new wash water.

Third, the conventional washing machine and washing method not only require a large number of strokes, such as a washing stroke, a rinsing stroke, a dehydration stroke, etc., but also has a problem that the total time for washing laundry is considerably long because the time required for each stroke is also long. .

The present invention has been made to solve the above-mentioned various problems with the prior art, an object of the present invention is to provide a washing method using a laundry machine of a new structure capable of washing laundry with a small amount of washing water consumption and low power consumption. It would be.

Washing method according to an embodiment of the present invention to achieve the above object is a steam supply step of supplying steam to the drum in which the laundry is put; And a contaminant separation step of discharging the steam in the drum by rotating the drum at least once at a low speed and a high speed after stopping the steam supply after a predetermined time, and centrifuging the contaminant from the laundry. It is characterized by.

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

First, the washing apparatus according to the embodiment of the present invention is largely attached to the main body 110, the outer tube 120, the drum 130, the drive motor 171, and steam divergence, as shown in Figs. It is configured to include a device, the embodiment is applied to a drum type washing machine.

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, the driving motor 171 is a motor driven to rotate the drum 130, and as shown in the related art, the driving force of the driving motor 171 using the belt 72 and the separate belt pulley 73. The drum 130 may be transferred to the drum 130, but is preferably provided to be directly axially coupled to the drum 130.

This is because the drive motor 171 according to the embodiment of the present invention should be able to rotate at a rotational speed of at least 2000 RPM or more is a structure in which the driving force loss can be reduced as much as possible.

In particular, the embodiment of the present invention is characterized in that the drive motor 171 is a motor configured to rotate up to 4000RPM.

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 provide steam into the drum 130 by heating the hot water into the drum 130, and is provided in the water reservoir 200 and the water reservoir 200 to receive the washing water for steam generation. It includes a heat supply unit 210 for providing a high temperature heat to vaporize the water and the steam supply pipe 220 is made of the flow of steam vaporized by the heat generating unit 210.

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.

In particular, the steam diverging device should be configured to enable selective steam divergence, and for this purpose, it is preferable to further include an on / off valve 221 for opening and closing the pipeline on the pipeline of the steam supply pipe 220.

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

First, the washing method according to an embodiment of the present invention is characterized in that the progress including the steam supply step, the contaminant separation step.

That is, in the washing method according to the embodiment of the present invention, the laundry can be washed only through the steam supplying step and the contaminant separating step, and the process thereof is as follows.

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

The steam is generated by evaporation of the water supplied to the steam dissipating device by the heat of the heat dissipating unit 210 constituting the steam dissipating device, and the generated steam is flowed while being guided by the steam supply pipe 220. After the opening and closing valve 221 is released through the injection nozzle 230 is discharged into the drum 130.

The steam supply process to the inside of the drum is preferably controlled to be continuously performed for a time (T1) 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.

Of course, if steam is provided for a long time is not preferable because the consumption and power consumption of the washing water can be increased compared to the soak effect.

In this case, the soaking of the laundry is a process of reaching a state in which contaminants can be separated from the laundry smoothly.

The washing of the laundry may be performed by the steam because the contaminants may be smoothly separated from the laundry affected by the steam, considering that the steam is formed at a high temperature and a large amount of water.

In addition, while the above-described steam supply is in progress by rotating the drum 130 at a low speed (for example, the rotational speed in the existing general washing stroke), the laundry is uniformly provided with the effect of the steam supplied into the drum 130. It is desirable to be able to.

In addition, as described above, the steam supplied into the drum 130 may be more than a temperature at which sterilization of the laundry is possible.

That is, by performing the washing and at the same time to sterilize the laundry to improve the user's satisfaction with the washing performance.

Then, when the contaminants are separated from the laundry by the steam supply for the predetermined time as described above, the controller controls the steam diverging device to stop the steam supply (S130).

In addition, the controller discharges steam in the drum 130 by alternately rotating the drum 130 at least once in a high speed and a low speed state by controlling the operation of the driving motor 171 and the contaminants from the laundry. And contaminant separation step of drying the laundry by centrifuging the water.

At this time, the contaminant separation stroke is preferably progressed by allowing the drum 130 to rotate at a low speed (S140) after the high speed rotation (S140).

This is to rotate the drum 130 at high speed to separate the water and contaminants contained in the laundry, and then rotate the drum 130 at a low speed so that the separated water and contaminants can be discharged to the outside of the drum.

If the drum 130 is rotated only at a high speed, moisture and contaminants separated from the laundry may remain in the drum 130 without being discharged to the outside of the drum 130, thereby driving the drum 130. When stopped, a problem arises that recontamination of the laundry may occur due to contaminants and moisture remaining in the drum 130.

Therefore, it is preferable that the drum 130 proceeds sequentially at least once while alternately rotating the high speed and the low speed.

In addition, the high speed rotation speed of the drum 130 is preferably set to a speed such that the contaminant-containing water and contaminants can be smoothly separated from the laundry and at the same time the laundry can achieve a predetermined dry state.

At this time, the predetermined dry state is that the laundry is dried about 70 to 95%, more preferably a dry state suitable for ironing.

In particular, the rotational speed such that the laundry can be dried as described above is preferably set to achieve a range of at least 2000 RPM or more, preferably 3000 to 4000 RPM.

Of course, it is also possible to perform drying by rotating the drum 130 at a rotational speed in the range of 2000 to 3000 RPM, in which case it is not possible to obtain the desired degree of laundry drying for a short time.

In addition, although the drum 130 may be rotated at a rotational speed of 4000 RPM or more, drying may be performed. In this case, a decrease in reliability of the washing machine is caused. That is, in the conventional general washing machine structure, various accessories did not sufficiently handle the rotation speed of the drum 130 described above, causing damage such as breakage.

Therefore, the rotational speed range of the drum 130 for the drying step is the range that can achieve a minimum drying effect on the laundry and at the same time the range of 3000 ~ 4000RPM that does not cause a decrease in reliability desirable.

In addition, the low speed of the rotation speed of the drum 130 is the steam in the drum 130 can be smoothly discharged at the same time the moisture containing contaminants separated from the laundry by the high speed rotation of the drum 130 is the drum ( 130) It is desirable to achieve a speed that can be smoothly discharged to the outside.

At this time, it is preferable that the rotation speed such that steam or moisture and contaminants can be smoothly discharged as described above is set at a speed of 100 RPM or less.

In particular, the process of rotating the drum 130 at low speed is preferably performed to be performed for a short time (T3) compared to the required time (T2) of the process of rotating the drum 130 at high speed.

This is to allow the discharge of water containing contaminants for a short time as smoothly as possible, to achieve the desired degree of laundry drying, that is, 70 to 95% dryness.

Then, as described above, when the contamination separation process using the high speed rotation of the drum 130 is completed, the controller stops the rotation of the drum 130 (S160) to terminate the washing.

At this time, the determination according to whether the contaminant separation process is completed may be made by various methods such as determining the weight of the laundry or determining the humidity in the drum 130, in the embodiment of the present invention by setting the administrative progress time The completion of the process is determined by counting whether the time has been reached.

As a result, the washing method according to the above-described embodiment of the present invention can perform washing with a minimum amount of washing water and a minimum power consumption.

On the other hand, a series of structures according to each embodiment of the present invention is not applied only to the drum type washing machine.

That is, although not shown may be applied to a general pulsator type washing machine.

As described above, the washing method according to the embodiment of the present invention has an effect that the washing process for the laundry can be performed with minimal washing water consumption and minimum power consumption.

In particular, in the washing method according to the embodiment of the present invention, the process of separating contaminants is performed a plurality of alternating high and low speed rotations of the drum, thereby preventing recontamination of the laundry due to contaminants in advance. This has an improved effect.
