Description

How to wash wool in a drum washing machine {WASHING METHOD FOR WOOL IN DRUM WASHER}

1 is a flowchart illustrating a wool washing method of a drum washing machine according to an embodiment of the present invention.

The present invention relates to a wool washing method of the drum washing machine, and more particularly, to increase the down time than the operation time during the washing operation during the wool washing through the drum washing machine as well as to remove the intermediate dehydration during the rinsing stroke and to rinse times and dehydration time. It relates to a wool washing method of a drum washing machine, which minimizes cloth damage.

In general, the low water type washing machine performs the washing operation by stirring the laundry immersed in the washing water in the water tank by rotating the pulsator, while the drum washing machine executes the washing operation by rotating the drum in which the laundry is put horizontally. Done. Therefore, the drum type washing machine has a mechanical structure different from that of a general low type washing machine.

Looking at the operation of the drum washing machine, when the user first puts laundry in the drum and turns on the start switch, the microcomputer detects the weight of the laundry put into the drum, determines the amount of water appropriate for the weight of the laundry, and starts water supply.

When the water supply proceeds to the water level set in the water tank surrounding the drum, the drum rotates according to the driving of the motor, and washing is performed by the drop of laundry. This washing proceeds for a time set by the weight of the laundry.

After the washing stroke is completed, the dehydration stroke is executed simultaneously with the drainage operation of discharging the contaminated washing water of the reservoir to the outside by the drainage pump, and the washing cycle is repeated for a predetermined number of times after the water supply is set again. In addition, when the washing administration is completed, the rinsing stroke and the dehydration stroke are subsequently performed.

This conventional washing stroke is performed by rotating the drum for 10 seconds in a predetermined rotational direction, and then giving a down time for 5 seconds. In particular, the wool is unlike the general washing stroke because the cloth may be easily damaged. After rotating for a second, a 15 second rest period is performed.

However, as described above, even if the rotation time of the drum is reduced and the down time is increased as compared to the general washing stroke, the wool washing method has a problem that is insufficient to solve the wool damage because it depends only on the operation time of the drum motor.

The present invention was created to solve the above problems, an object of the present invention is to increase the down time than the operating time during the washing operation during the wool washing through the drum washing machine as well as to delete the intermediate dehydration during the rinsing administration and the number of rinses It is to provide a wool washing method of the drum washing machine to reduce the dehydration time to minimize cloth damage.

The present invention for achieving the above object in the wool washing method of the drum washing machine to control the operation time and rest time of the washing administration, the step of setting the washing conditions after selecting the wool washing, and the cold water after setting the washing conditions The step of supplying water, and the step of detecting the washing water temperature after supplying the cold water to maintain a constant temperature, the step of maintaining the washing water temperature after performing the wool washing administration, and after the wool washing administration A step of stirring the laundry while proceeding and draining at the same time, and performing a rinsing stroke without intermediate dehydration after the water and draining at the same time for a certain time, and performing a dehydration stroke at a low speed after performing a certain number of rinsing stroke Characterized in that it comprises a step.

In the present invention, the washing water temperature is characterized by maintaining 10 to 18 ℃.

In the present invention, when the water supply and drainage at the same time, the stirring of the laundry is characterized in that proceeds once.

In the present invention, a predetermined number of times the rinsing stroke is characterized in that twice.

In the present invention, the low speed dehydration stroke is characterized in that the dehydration time is within 3 minutes at 400 rpm.

The present invention made as described above not only reduces the number of rinsing strokes while keeping the washing water temperature constant, but also reduces cloth damage by not performing intermediate dehydration during the rinsing stroke, while the rinsing effect proceeds simultaneously while draining water for the rinsing stroke. Stir the laundry to increase the rinsing effect, while dehydrating at low rpm during dehydration administration to reduce the main dehydration time to prevent damage to the cloth.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings, and the same parts as in the prior art use the same reference numerals and names. In addition, the present embodiment is not intended to limit the scope of the present invention, but is presented by way of example only and those skilled in the art will be capable of many modifications within the technical spirit of the present invention.

1 is a flowchart illustrating a wool washing method of a drum washing machine according to an embodiment of the present invention.

First, the wool washing course of the drum washing machine is selected and washing conditions such as the type of laundry and the washing time are set (S10).

For example, according to the type of laundry, a blouse or the like is set at a washing time of 5 minutes, a laundry of a general wool material is set at 15 minutes, and a blanket is set at 30 minutes.

After setting the washing conditions so that the cold water is supplied to keep the washing water temperature 10 to 18 ℃ (S12) (S14).

If warm water is used, the cloth may be deformed, so use cold water but keep the washing water temperature constant.

When the water supply is completed as described above, the process of washing the drum for 2 seconds by rotating the drum for 2 seconds and stopping for 15 seconds is repeatedly performed for the set washing time (S16).

When the wool washing administration is completed in this way, while draining, the draining proceeds at the same time while watering for the rinsing administration to drain the contaminated washing water contained in the laundry (S18).

At this time, the drum is rotated once to stir the laundry to effectively drain the contaminated washing water (S20).

This proceeds with the water supply and drainage at the same time for a predetermined time and then performs a rinsing stroke (S22) (S24).

Rinse administration is repeated twice without the usual intermediate dehydration (S26).

In order to minimize the deformation of the cloth during the rinsing cycle, the rinsing stroke is limited to two times without intermediate dehydration, and the washing is stirred to increase the rinsing effect while simultaneously proceeding with drainage during water supply to discharge contaminated washing water. do.

In this way, when the rinse stroke is completed, the dehydration process is performed within 3 minutes of the main dehydration at a low speed of 400 rpm to minimize the deformation of the cloth during the dehydration administration (S28).

As described above, the present invention not only increases the downtime more than the operation time during the washing operation during the wool washing through the drum washing machine, but also easily removes the intermediate dehydration during the rinsing administration and minimizes the rinsing frequency and the dehydration time by minimizing the damage to the cloth. In addition to washing wool through the drum washing machine has the advantage of reducing the washing cost.
