Hereinafter, an operation process and an effect for removing wrinkles of clothes in a washing machine and a dryer having a steam generator configured as described above will be described.

4 is an operation flowchart of a wrinkle removal method of clothes using steam according to the present invention, the wrinkle removal method of the present invention can be performed during the drying stroke or in an independent stroke irrespective of the drying stroke. Therefore, when the drying stroke is performed, the wrinkle removal stroke may be set as the default or a separate option key may be provided so that the wrinkle removal stroke may be performed only when the user presses the option key.

The user inputs the garment (laundry) to remove wrinkles in the rotating drum 12 and then selects the sole wrinkle removal course or option (after the stroke continuous wrinkle removal course) (S100).

At this time, the clothing inside the rotating drum 12 may be a garment that requires less contamination and only wrinkle removal occurred during wearing or storage, and may be laundry after the washing process.

In addition, after the user selects information such as wrinkle degree of the clothes, material and softener input (S200), when the operation is turned on (S300) to detect the load of the clothes put into the rotary drum 12 (S400).

Therefore, the drying temperature, RPM and operation rate of the rotating drum 12 and the reverse direction, the number of wrinkles are removed, and the steam supply time, drying temperature and drying time are set according to the degree of wrinkles, material and load of the garment. To perform the wrinkle removal administration (S500).

This wrinkle elimination administration is repeated as many times as the number of wrinkles, material and load is set.The more steam is removed, the shorter the steam supply time is, so the initial steam supply time is the longest and the repeated steam supply time is shorter. In addition, the drying temperature is gradually lowered so that the final drying temperature is about 50 ° C so that steam and drying, heating, and cooling are repeated during the wrinkle removal stroke.

In this way, when the set number of wrinkles is removed, the operation is terminated by stopping all operations of the wrinkle removal stroke (S600).

The wrinkle removal stroke (S500) will be described in detail with reference to FIG.

When the wrinkle removal course is selected, the control unit 140 controls the drying apparatus 40 to supply hot air for preheating and dust removal (S510).

The preheating hot air supply will be described in detail as follows.

By the operation of the motor 13, the rotating drum 12 gradually rotates at a predetermined set RPM and a set operation rate. When the drying fan 41 operates in this state, the air in the water tank 11 is sucked toward the drying fan 41 through the condensation duct 43, and then again the water tank 11 through the drying duct 42. The circulation discharged to the inside is repeated.

At this time, the air of the drying duct 42 is introduced into the rotary drum 12 in a heated state by the drying heater 44, the temperature inside the rotary drum 12 and the clothing inside the rotary drum 12 is hot air Is heated by.

As such, the hot air is first supplied before spraying steam on the clothes to increase the internal temperature of the rotating drum 12, thereby preventing freezing of the door 15 in the winter, and the drying duct 42 and the door 15. It is possible to spray the steam smoothly by increasing the temperature of, and to remove the dust and dirt attached to the clothes by supplying hot air to the clothes.

When preheating hot air is supplied, the RPM and operation rate of the rotating drum 12 are set by the designer according to experimental data, and may be changed according to product capacity or design conditions. It may not be rotated.

When the preheating hot air is supplied, since the internal temperature of the rotating drum 12 starts to rise due to the hot air injected into the rotary drum 12 through the drying duct 42, the internal temperature D _T of the drying duct 42 is increased. ) Is detected by the temperature sensing unit 120 and output to the control unit 140 (S520).

The control unit 140 compares the internal temperature D _{T of} the drying duct 42 input from the temperature sensing unit 120 with the preset temperature D _TS ; It is determined whether the temperature D _T is equal to or greater than the set temperature D _TS (S530).

If the internal temperature D _T is equal to or higher than the set temperature D _TS , the controller 140 determines that the internal temperature of the rotating drum 12 is sufficiently high to allow the steam to be smoothly injected, and stops the preheating hot air supply.

After the preheating hot air supply is completed, the controller 140 controls the water supply device 20 and the steam generator 30 to supply steam into the rotating drum 12 for a predetermined time while injecting a softening agent for imparting fragrance ( S540).

The softener and the steam supply will be described in detail as follows.

By the operation of the motor 13 so that the clothes inside the rotating drum 12 are dropped, the rotating drum 12 is set at a predetermined set RPM and a set operation ratio (on / off ratio, for example, 20 seconds on / 2 seconds off). To rotate slowly. In this state, the steam valve 25 is opened and water is supplied to the steam generator 30 through the steam water supply pipe 24, and the water supplied to the steam generator 30 is momentarily heated by the steam heater 31. Generates steam at a temperature higher than 100 ° C. This high temperature steam is supplied into the rotary drum 12 through the steam supply pipe 33 and is directly injected to the clothes.

As such, by directly spraying steam on the inner garment of the water tank 11, it is possible to remove wrinkles by acting on the rearrangement of crosslinking in the fiber, and can also be expected to sterilize the garment.

In the steam supply, the set RPM, the operation rate, the reversal direction of the rotary drum 12 is a value set according to the degree of wrinkle of the clothes, material and load.

At the same time, the water supply valve 22 is opened and water is supplied to the detergent supply device 18 through the water supply pipe 21, and the softener in the detergent supply device 18 is supplied by the water supplied to the detergent supply device 18. Various aromatic substances) are dissolved and supplied to the water tank 11. To this end, the user must put the softener into the detergent supply device 18 in advance.

At this time, when supplying water in which the softening agent is dissolved, the driving direction, RPM and operation rate of the rotating drum 12 are adjusted according to the position and direction of the water supply port so that the water supplied does not directly contact the clothes. For example, when the position of the water supply port is located on the left side of the water tank 11 when viewed from the front of the washing machine, the rotating drum 12 is rotated counterclockwise and at a low RPM (about 30 RPM) so that the clothes are rotated. Place it on the right side so that the softener does not get on the clothing

Thereafter, the steam supply time of the steam generator 30 is checked to determine whether a predetermined time (T1; the total driving time of the steam generator from about 10 minutes) has elapsed since the preheating of the steam heater (S550). When the time T1 elapses, the operation of the steam generator 30 is stopped.

After the steam supply is completed, the control unit 140 controls the drying apparatus 40 to supply the drying hot air to the set temperature (lower than general drying information; not higher than about 70 ° C.) inside the rotating drum 12 for a set time. (S560).

The dry hot air supply is described in detail as follows.

The rotating drum 12 is gradually rotated at a predetermined set RPM and a set operation rate by the operation of the motor 13 so that the clothes inside the rotating drum 12 fall. When the drying fan 41 operates in this state, the air in the water tank 11 is sucked toward the drying fan 41 through the condensation duct 43, and then again the water tank 11 through the drying duct 42. The circulation discharged to the inside is repeated.

At this time, the air of the drying duct 42 is introduced into the rotating drum 12 in a heated state by the drying heater 44, and the clothes inside the rotating drum 12 are dried while being heated by hot air.

In this way, by supplying hot air to the clothes sprayed steam can effectively remove the wrinkles without ironing, it does not need to go through a separate drying process can easily manage the clothes.

When the dry hot air is supplied, the set RPM, operation rate, and reversal direction of the rotating drum 12 are set according to the degree of wrinkles, material, and load of clothes, and are larger than those of steam supply.

Thereafter, the hot air supply time of the drying apparatus 40 is checked to determine whether a predetermined time (T2; about 15 minutes) has elapsed (S570), and when the predetermined time (T2) has elapsed, the controller 140 controls the drying sensor ( Detecting the temperature and humidity of the clothing through 47) to determine whether the drying is complete (S580).

If the drying is not completed, it is fed back to the step S560 to continue supplying hot air, and when the drying is complete, the operation of the drying apparatus 40 is terminated.

In the present invention, the conditions for determining whether the drying is completed according to the temperature and humidity of the clothing have been described as an example of determining after the hot air supply time has elapsed, but this determination condition may be determined in advance before the hot air supply time elapses. Therefore, the hot air supply can be stopped before the set time.

On the other hand, in one embodiment of the present invention has been described using a dry drum washing machine as an example, the present invention is not limited to this, of course, can be applied to any washing machine or dryer capable of supplying steam and hot air.

As described above, according to the method for removing wrinkles of clothing according to the present invention, as a separate wrinkle removing course using steam, it is possible to remove wrinkles of clothing that has been washed, as well as wrinkles generated during wearing or storage.

In addition, the present invention can directly remove the wrinkles without washing by spraying high-temperature steam directly to the clothes that need less pollution and only wrinkle removal, the optimum amount of humidification, drying temperature according to the degree of wrinkles, material and load of the clothes And through the drum operation control can increase the wrinkle removal effect.

In addition, the present invention can supply hot air before spraying the steam to remove the dust and dirt attached to the smooth spray of the steam and the clothing, and by adding a softener when supplying steam to remove the unpleasant odor of the clothing and aroma You can give it.
