Hereinafter, a driving method for removing wrinkles among driving methods according to a preferred embodiment of the present invention using the structure of the above-described washing apparatus will be described with reference to the flowcharts of FIGS. 3 and 4.

First, referring to FIG. 3, a user provides a wrinkle removing object (hereinafter, referred to as 'clothing') to remove wrinkles into the drum 300, and operates to remove wrinkles of the washing apparatus (hereinafter, “wrinkling”). Step S10) is performed (S10).

At this time, the wrinkle removal course is a target of the wrinkled clothes in a dry state, the dehydration is completed, the clothes containing a small amount of water may also be the target.

Then, when the supply of the clothes as described above is completed, the controller (not shown) controls the steam supply unit 400 to perform a steam supply process for supplying high temperature steam into the drum 300 (S20; Hereinafter referred to as the 'steam supply stage').

That is, by supplying steam water to the steam generator 410 and generating heat, steam water is vaporized to generate steam, and then the generated steam is supplied into the drum 300.

The steam is intended to allow the clothing to contain a small amount of moisture, thereby the clothing is in a state in which smooth wrinkles can be removed. In particular, when considering that the steam is a high temperature state can be more smoothly removed wrinkles of the clothing.

Steam generated by the steam generator 410 is injected into the drum 300 through the steam supply pipe 420. When steam is supplied into the drum 300 as described above, it is preferable to control the driving unit 310 to rotate the drum 300 so that the steam can be more smoothly supplied to the clothes.

In particular, the drum 300 is controlled not to rotate in one direction but to be reversed left and right to prevent the clothes inside the drum 300 from being stuck together, and the steam can be more evenly supplied to all parts of the clothes. More preferably.

As described above, the steam supply process for supplying steam into the drum 300 is continuously performed until the temperature inside the drum 300 reaches a preset temperature T.

At this time, the preset temperature is a temperature of 40 ℃ or more, the standard of this temperature is because the temperature inside the drum 300 is the most effective temperature for removing wrinkles of the clothes is above 40 ℃.

Of course, the higher the temperature, the smoother the removal of the clothing may proceed. However, when the temperature inside the drum 300 is too high, problems such as damage or deformation of the cloth may occur, and a problem may occur that the clothes may be excessively wet by a large amount of steam.

Therefore, the set temperature (T) achieves excellent wrinkle removal performance, it is preferable that the temperature of the temperature between 40 ℃ ~ 60 ℃ can be prevented.

When the temperature inside the drum 300 reaches the set temperature T by the above-described process, the steam supply unit 400 is controlled to stop the steam supply.

Subsequently, a drum rotation step S30 is performed in which the drum 300 is rotated for a predetermined set time t1 while the steam supply is stopped and continues the wrinkle removal process. In the drum rotation step S30, the set time t1 at which the drum 300 rotates is preferably set in proportion to the amount of clothes provided in the drum, that is, the quantity of the clothes.

That is, it is preferable that a large amount of drum is set for a relatively long drum rotation time to achieve sufficient wrinkle removal, and a small amount of drum is set for a relatively short drum rotation time to obtain a satisfactory wrinkle removal effect within a short time.

After the wrinkle removal course is completed through the steam supply step S20 and the drum rotation step S30 as described above, when the user selects to perform the wrinkle removal course one more time in succession, the controller executes the preset continuous course. Perform the mode.

The continuous course execution mode is described in detail with reference to FIG. 4 as follows.

When the continuous course execution mode is executed, the controller checks the temperature inside the drum measured by the temperature sensor 500 (S41). If the measured temperature is lower than the predetermined set temperature (T1) to repeat the steam supply step (S20) and the drum rotation step (S30) continuously in the same manner as described above to repeat the wrinkle removal operation.

However, if the measured temperature is lower than the set temperature in the steam supply step (S20) but higher than the first set temperature (T1), the controller operates the blower fan 630 of the air supply unit 600 into the drum. Supplying low-temperature air to lower the temperature inside the drum (S42). When the internal temperature of the drum drops below the first set temperature T1 (S431), the steam supply step S20 and the drum rotation step S30 are continuously performed again to repeat the wrinkle removal operation.

As such, when the user selects to continuously perform the wrinkle removal course, the reason for repeating the wrinkle removal course by supplying steam only when the drum internal temperature is lower than or equal to a predetermined set temperature (T1) is provided. Even when the steam is supplied, the time to reach the temperature (T) to stop the steam supply is very short, so that sufficient steam is not supplied into the drum, and thus the effect of performing the continuous wrinkle elimination course is very small.

On the other hand, in the above embodiment, in the continuous course execution mode, the blowing fan 630 was operated until the internal temperature of the drum became equal to or lower than the set temperature T1 to supply cold air.

However, as shown in FIG. 5, the blowing fan 630 may be operated for a predetermined time t2 to supply cold air (S432).

In addition, in the above-described embodiment of the driving method, the operation of the blower fan is stopped during continuous course operation, and then the steam supply step S20 is executed. Alternatively, the steam supply step S20 is performed while the blower fan is operating. May be partially performed. In this case, even when the steam supply is made, the temperature inside the drum is slowly increased to increase the time taken for the drum internal temperature to rise to the steam supply stop temperature (T).

As described above, the operating method of the laundry apparatus according to the embodiment of the present invention has the effect that the satisfaction of the use of the product can be improved by only the wrinkle removal course for refreshing such as removing wrinkles of clothing. .

In particular, when the user selects and executes the wrinkle elimination course continuously, sufficient steam may be supplied into the drum, thereby improving the effect of removing wrinkles during continuous course operation.
