Hereinafter, a preferred embodiment according to the above-described form of the present invention and preferred embodiments of the washing method of the present invention will be described in more detail with reference to FIGS. 3 to 6.                     

First, the washing machine according to an embodiment of the present invention includes a main body 110, an outer tub 120, a drum 130, a drying device, and a steam dissipation device as shown in FIG. The drying combined drum washing machine which can perform a stroke and a drying stroke is taken as the Example.

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, a plurality of through-holes (not shown) are formed on the circumferential surface of the drum 130 so that washing water and steam can be introduced into the drum 130.

In addition, the steam dissipation device is configured to provide a predetermined amount of steam into the drum 130, at least one is provided.

The steam dissipation device is installed to vaporize the water with high temperature heat to provide it into the drum 130, and by the heat generating unit 210 and the heat generating unit 210 to provide high temperature heat to vaporize the water. It is configured to include a steam supply pipe 220 through which the flow of steam is steamed.

In addition, the steam diverging device further comprises a spray nozzle 230 for discharging steam flowing through the steam supply pipe 220 into the drum 130.

At this time, the injection nozzle 230 is configured in the shape of a nozzle (nozzle) to enable a smooth divergence of steam, the end of the discharge of steam is preferably installed to face the drum 130.

Of course, as shown in Figure 4 attached to the end of the injection nozzle 230 in which the discharge of steam is made may be configured to only communicate with the inside of the outer tub 120, in this case, the steam directly into the laundry in the drum (130) It is not preferred because it is not sprayed.

In particular, the steam dissipation device should be configured to enable the divergence of the selective steam, for this purpose further comprises an on-off valve 221 for opening and closing of the pipeline on the pipeline of the steam supply pipe 220 Yes.

In addition, the drying apparatus includes a hot air supply pipe 181 for providing hot air dried in the drum 130 and a drying heater 182 for heating air flowing in the hot air supply pipe 181. .

At this time, it is preferable to further include a blowing fan 183 is driven to forcibly blow the air in the hot air supply pipe 181 on the pipeline of the hot air supply pipe (181).

Washing method according to the first embodiment of the present invention to perform the washing stroke in the structure of the washing machine described above basically wash water supply step, washing step, rinsing step, final dewatering step, drying step, and steam injection Characterized in that the steps proceed sequentially.

Hereinafter, with reference to the accompanying flow chart of Figure 5 will be described in more detail according to the progress of each process provided in the washing method according to the first embodiment of the present invention according to the procedure.

First, before the operation according to the first embodiment of the present invention described above, a controller (not shown) for controlling the operation of the washing machine continuously checks generation of a request for executing the washing operation by the user (S110). .

If the user selects to perform the operation of the washing machine while the laundry is put in the drum 130, the controller performs an appropriate amount of washing water supply (S120) for the washing stroke.

At this time, the appropriate amount is a predetermined amount according to the amount of laundry.

In the process of supplying the wash water, it is preferable to supply an appropriate amount of detergent together with the wash water.

When the supply of the washing water is completed, the drum 130 is rotated for the set time (S130).

In other words, by forcibly flowing the wash water separates the washing time in the laundry by a complex action, such as the friction between the water flow and the laundry, the emulsification of the detergent to perform the washing stroke.

At this time, the rotation direction, the rotational speed, the stroke progress time, etc. of the drum 130 for the washing stroke is preferably the same as the conventional washing stroke.

When the washing stroke as described above is completed, the remaining washing water in the drum 130 is drained, and when the draining is completed, intermediate dehydration is performed through the high speed rotation of the drum 130.

When the intermediate dehydration is completed, at least one rinsing stroke is performed (S140).

At this time, when the rinse cycle is a plurality of times, drainage, dehydration, rewatering, and the like are repeatedly performed.

When the rinsing process is completed, the final dehydration stroke is performed (S150).

At this time, the final dehydration stroke is a process of centrifuging the water from the laundry by rotating the drum 130 at a high speed. Unlike the intermediate dehydration, most of the water is discharged in the final dehydration process.

When the final dehydration is completed, the drying heater 182 generates heat and the blowing fan 183 is driven while a drying stroke is performed (S160).

At this time, the drying stroke is a series of processes to perform a forced drying of the laundry in the drum 130 by providing a high temperature heat into the drum (130).

The drying stroke is performed for a set time, and when the set time is reached, the drying heater 182 is turned off and the driving of the blower fan 183 is stopped to complete the drying stroke.

When the drying stroke is completed, the controller operates a steam releasing device to perform a steam spraying stroke for injecting steam to the laundry dried inside the drum 130 (S170).                     

At this time, the steam is sprayed directly to the laundry in the spray state, the injection pressure is preferably at least to the extent that the anion can be generated 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 a long time, it is only performed for an appropriate time (for example, 3 to 10 minutes) since the wetness of the laundry may occur as the amount of steam provided to the laundry is excessively increased. This is preferred.

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.

Then, when the steam injection step is completed, it is preferable to drive the blowing fan 183 constituting the drying apparatus (S180) so that the steam in the drum 130 is quickly discharged.

As a result, if the driving of the blower fan 183 is stopped (S190) after the complete discharge of the steam is complete washing is finished.

On the other hand, in the laundry method according to the first embodiment of the present invention described above, even if the laundry is completed, or if the user vacated for a long time, taking out the laundry is not made because the generation of static electricity is intensified, Odor can be generated.

In addition, recontamination of the laundry may occur as well as the ironing is not easy due to the continuation of the crumpled state.

Therefore, in the second embodiment of the present invention, the steam spraying step is not immediately performed immediately after the drying step of the series of washing processes according to the first embodiment of the present invention described above, but the actual laundry is requested to be taken out by the user. Characterized in that it is performed when this occurs.

That is, as shown in the flowchart of FIG. 6, when the entire stroke for washing is completed, the request generation for taking out the laundry is confirmed (S210). When the request is generated, a predetermined time is performed before the unlocking of the door 140 is performed. While operating the steam dissipation device (S220) is to perform the supply of negative ions to the laundry and to refresh the laundry.

In this case, the steam is sprayed directly to the laundry in the spray state, the injection pressure is preferably at least to the extent that the anion can be generated by the impact force when the steam hits the laundry.

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

In addition, the temperature of the steam is preferably provided at a temperature that is capable of sterilizing the laundry, for example, at a temperature of 60 ° C. (preferably 70 ° C.) or more, so that re-sterilization may be performed even if re-contamination occurs.

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

At this time, it is preferable that the execution time of the steam injection stroke may be variable in consideration of the time for leaving the laundry, that is, the time from the completion of the actual washing until the request for taking out the laundry occurs.

For example, the longer the storage time of laundry, the longer the steam injection stroke is performed. Of course, it is preferable not to perform the laundry until wet.

When the set time ends, the operation of the steam dissipation device is stopped (S230) to complete the steam injection stroke, and by releasing the lock of the door to control the taking out of the laundry (S240) to terminate the whole process.

As described above, the washing method according to the first embodiment of the present invention has an effect of generating anions by spraying steam in a spray state on the laundry to which drying is completed to remove static electricity and odor components.

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.

In addition, in the laundry method according to the second embodiment of the present invention, even when the laundry is left in the drum for a long time, the laundry can be refreshed by spraying hot steam forming a spray state with the laundry immediately before taking out the laundry. The satisfaction with the user has an improved effect.
