Therefore, definitions of these terms should be made based on the contents throughout the specification.

2 is a view showing a sneaker washing method of the drum washing machine according to an embodiment of the present invention as a flow.

In the general washing process, the weight of the laundry put into the drum is measured, and the level of water to be supplied is determined according to the measured weight of the laundry, and clean water is supplied to the tub provided at the outside of the drum.

However, in the present invention, the process of measuring the weight of such laundry is omitted, and water is supplied to the tub at a predetermined water level. (S10)

Here, the set water level is set equal to the water supply level set when the measured weight of the laundry is within 4 kg. That is, water the tub with a low water level to slightly wet the sneakers. At this time, the motor is stopped while the water supply is in progress, so that the drum is not rotated left and right, so that the sneaker hits the inner wall of the drum and does not make a hit sound.

After the water supply is completed by the water level set in the tub as described above, by rotating the motor to 30 ~ 55RPM, the drum is rotated to proceed with the main washing process (S12).

Before proceeding to the washing process (S12) it is also possible to perform a soaking process of heating the water to be washed to remove the splatters on the surface of the sneakers for a certain time.

During the soaking process, it is appropriate to heat the wash water to 40 ℃ ± 5 ℃. Heating the wash water to a high temperature may weaken the adhesion site of the sneakers or deform the shape of the sneakers.

After this washing process (S12) is completed, the rinsing process is performed.

The rinsing process is first used in this washing process (S12) to drain the washed water washed out to the outside (S14), the intermediate dehydration (S16) to remove the water absorbed by the sneakers, and clean wash water to the tub It consists of water supply (S18) which supplies water, and rinsing (S20) which rinses a sneaker with this water supply clean washing water.

At this time, the intermediate dehydration (S16) for selectively removing the water absorbed in the sneakers may be omitted.

Intermediate dehydration (S16) is not the rotation of the drum by rotating the motor at a high RPM of about 700 ~ 750RPM as in the general washing process, but by rotating the motor left and right at 40 ~ 45RPM to simply drop the moisture of the sneakers It is characterized by alternating dehydration in which water is removed.

In the alternate dehydration, the rotation of the motor lasts 10 seconds each, and there is a 10-second stop period between the rotations.

When the intermediate dehydration (S16) is finished, when clean water is resupplied to the tub, the motor is stopped to prevent the drum from rotating.

This entire rinsing process is appropriate to proceed 2-3 times (S22).

After the rinsing process is completed like this, the washing water used in the final rinsing (S20) is discharged to the outside (S24), and the present dehydration (S26) is performed.

In this dehydration (S26), as in the middle dehydration proceeding in the rinsing process, the motor is alternately rotated by 40 to 45 RPM for 10 seconds each to the left and right, and alternating dehydration is performed while maintaining the stop section for 10 seconds between each rotation.

By rotating the motor left and right at a low RPM as described above, it is possible to minimize the problem that the sneaker hits the inner wall of the drum during the conventional high RPM rotation and makes a large blow sound or the washing machine vibrates violently.

The dehydration in this dehydration (S26) lasts for 3 to 15 minutes, and obtains the effect of dropping the moisture absorbed by the sneakers by the drum rotating left and right alternately (S28).

On the other hand, in addition to the alternating dehydration it is also possible to proceed further high-speed dehydration by rotating the motor at a high RPM of 400 ± 50 RPM.

If, in the drum washing machine to which the drying function is added, the low temperature drying (S30) may be further performed after the dehydration (S26).

In low temperature drying (S30), the sneakers are dried at a relatively low temperature of 40 ± 5 ° C. instead of setting a high temperature as when drying general clothing.

At this time, the heater is turned on for 2 to 10 seconds at 30 ℃ to 40 ℃ and turned off for 30 to 60 seconds at 45 ℃ to 55 ℃ to maintain 40 ± 5 ℃.

If the sneaker is dried at a high temperature in the low temperature drying (S30), the adhesive portion of the sneaker may be weakened or the rubber sneaker may be deformed.

At this time, in the case of sneakers sewn on the side of the sneakers with seams, the drying temperature may be set slightly higher.

This low temperature drying (S30) lasts for 30 minutes ± 5 minutes, and rotates the motor intermittently left and right alternately. That is, the motor is rotated for 2 seconds each on the left and right sides, and a long stop section of 30 seconds is placed between each rotation. At this time, the motor rotates at 35 to 45 RPM.

Finally, the warmed sneakers during the low temperature drying (S30) is cooled for 5 minutes (S32). At this time, the wrinkle prevention process is omitted.

As such, if the soil on the sneakers is left in the tub of the washing machine after the washing of the sneakers is finished, it may act as a pollution source when the general washing is performed (S36).

The tub washing (S36) is to perform the rinsing and dehydration about once, and such tub washing (S36) can be proceeded if the user selects within about 3 minutes to 5 minutes within the set time after the sneaker washing is finished ( S34).

If the drum washing machine does not have a drying function, the washing through the water (S34) is performed after this dehydration (S26) is completed (S28).

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and various modifications and equivalent other embodiments are possible to those skilled in the art. Will understand. Therefore, the technical protection scope of the present invention will be defined by the claims below.
