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

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

First, the washing method according to the embodiment of the present invention is characterized in that the washing step, the rinsing step, the final dehydration step, and the drying step is included.

The washing method is similar to the conventional washing method at first glance, the present invention, unlike the conventional washing method in which the drying step is carried out through the supply of hot air may be capable of drying the laundry at a high speed rotation of the drum 130 It would be.

This will be described in more detail as follows.

First, the washing step proceeds (S120) by a request for washing operation of the user (S110).

The washing step is a step of performing a washing process for the laundry for a predetermined time using the emulsification by the detergent and the friction between the laundry and the drum 130.

Then, when the washing stroke is completed, the rinsing step is performed after draining and intermediate dehydration (S130).

The rinsing step is a step of performing at least one rinsing stroke to completely remove the detergent and foreign matters remaining in the laundry.

Then, when the rinsing stroke is completed, the final dehydration step is performed after the drainage of the wash water used for the rinsing is performed (S140).

The final dewatering step is a step of finally rotating the drum to perform a dehydration stroke.

At this time, the rotational speed of the drum in the final dehydration stroke is set to be in the range of approximately 600 ~ 2000RPM.

The final dehydration step as described above is preferably set to be a process for minimizing the moisture contained in the laundry.

This, when considering that the drum is rotated at a speed of at least 2000RPM or more during the drying step performed after the final dehydration step, if the content of water in the laundry in the drum 130 is high drum 130 for the drying step This is because severe vibration occurs during rotation of), which causes a decrease in reliability of the product.

Therefore, before the drying step is performed, it is preferable to minimize the moisture contained in the laundry, and the present invention is characterized in that the drying step can be performed through the final dehydration step.

Then, when the final dehydration step is completed as described above, the drying step for performing a drying stroke for the laundry at a high speed rotation of the drum proceeds (S150).

At this time, it is preferable that the rotational speed of the drum achieves at least a higher speed than at the final dehydration stroke.

This, by rotating the rotation speed of the drum 130 at a high speed of more than 2000RPM so that the moisture contained in the laundry can be separated from the laundry by applying the centrifugal force by the high-speed rotation of the drum, the same as the drying effect using the hot air supply To achieve the effect.

In particular, in order to obtain the maximum drying performance, it is preferable that the rotational speed of the drum 130 is in a range of approximately 3000 to 4000 RPM.

Of course, it is also possible to perform drying by rotating the drum 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 drying of the laundry in 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.

As described above, if the drum 130 is rotated at a high speed of about 3000 to 4000 RPM and the stroke is performed for a predetermined time, the moisture contained in the laundry is centrifuged from the laundry by applying the centrifugal force by the high speed rotation of the drum 130. do.

This allows the laundry to achieve the desired degree of drying.

In particular, the drying step is preferably to be carried out until the laundry can be dried approximately 70 to 95%.

At this time, the method of confirming the end time of the drying step according to the dryness of the laundry may be proceeded by continuously checking the humidity in the drum 130 with a humidity sensor, the drum for a predetermined time according to the amount of laundry When the high-speed rotation of the 130 is made, it may be determined that the corresponding dryness is satisfied and the drying step ends.

After the drying step is completed, a steam injection step (S160) of discharging steam into the drum 130 into which laundry is introduced by operating a steam releasing device is performed.

At this time, the steam is sprayed directly to the laundry in the spray state, the injection pressure is preferably at least to achieve the degree of anion generation by the impact force when the steam hits the laundry.

That is, the generation of the negative ions to be made so that the static electricity can be removed by the negative ions. Of course, due to the anion described above, the smell of laundry can also be removed.

Of course, the anion is not generated only when the steam in the spray state hits the laundry, but the anion may be generated even when the steam hits the wall surface of the drum 130.

In particular, the temperature of the steam is preferably provided at a temperature such that it is possible to sterilize the laundry, for example, 60 ℃ (preferably 70 ℃) or more.

In addition, the steam injection stroke is most preferably performed only for a time enough to refresh the dry laundry.

At this time, the refresh is a process to fold the laundry to be unfolded, which is to fold the laundry by spraying the hot water of the steam state, such as a steam iron to the laundry.

In particular, when the laundry is excessively dried in the above-described drying stroke, the ironing of the laundry is difficult, but the refreshing effect makes it possible to iron the laundry smoothly.

However, if the refreshing process is performed for too long time, since the wetness of the laundry may be generated as the amount of steam provided to the laundry is excessively increased, it is only performed for an appropriate time (for example, 3 to 10 minutes). desirable.

In addition, it is preferable to control the drum 130 to rotate while the steam injection stroke is performed, since the uniform static elimination effect and the refresh effect of all laundry can be obtained, but are not limited thereto.

Therefore, if the injection of the steam has been performed for a set time, a series of processes for removing the static electricity is completed by stopping the operation of the steam dissipation device (S170), thereby ending the overall washing.

As described above, the laundry method according to an embodiment of the present invention can be dried by the high speed rotation of the drum, without having to provide a separate drying device for drying the laundry by providing a high temperature hot air This has the effect of simplifying the overall structure.

In particular, by allowing the drying process of the laundry using the high speed rotation of the drum can be carried out after the final dehydration stroke is completed, it is possible to prevent in advance that the reliability of the drum at high speed rotation is degraded by a large amount of wash water, It has the effect that the maximum drying performance can be obtained.

In addition, the washing method according to the embodiment of the present invention has the effect that it is possible to remove the static electricity and odor components by generating negative ions by spraying the steam in a spray state to the laundry is dried.

In addition, the sterilization performance is further improved by again sterilizing the dry laundry.

In addition, it is possible to achieve a state most suitable for ironing by refreshing the dry laundry is made.
