A mode, an odor removing mode, and the like may be implemented, and various modes such as these may be selected and adjusted through various buttons on the control panel 6 side.

3 is a view illustrating an example of a method for removing an odor from a washing machine according to the present invention. Referring to FIG. 3, a method of removing an odor from a washing machine configured as described above is as follows.

First, in the first step, an object to be odor removed is put into the drum 20, and then an odor removing mode is set. (See S1)

Here, the object to be odor is suitable as a kind of fiber, such as curtains, sporting goods, etc., in addition to shoes, clothing, such an object, after opening the door 4, the drum 20 through the inlet (2h) ) Is put inside.

And, the user sets the odor removal mode by using the button on the control panel 6 side, if the odor removal mode is set, the operation of the various components in accordance with the odor removal program previously input to the control panel Adjusted.

Next, when the odor removing mode is set in the first step, the drum 20 is rotated at a low speed, and deodorization and dehumidification are performed while hot air is supplied to the drum 20 for a first predetermined time. (See S2, S3).

At this time, while the odor removing mode is in progress, the drum 20 is rotated at a low speed by 1 G or less by the driving motor 30 so that the lift 22 pulls up an object, and then repeatedly drops the object from the upper side. By mixing the objects with each other, thereby increasing the deodorization and dehumidification effect.

In more detail, when the hot air is supplied into the drum 20, the drying heater 42 and the blowing fan 44 are operated to heat the hot air from the drying duct 40 into the tub 10. Supplied, forced flow is generated in the tub 10 and the drum 20, the odor factor and moisture contained in the object is included in the air and exhausted, but may be introduced into the condensation duct 46 and recycled, It may be discharged to the outside through a separate hole.

At this time, as the drum 20 is rotated, the odor factor and moisture are separated from the object by centrifugal force to exit the communication hole 20h of the drum, and then may be exhausted.

At the same time, the condensate water supply valve is opened to allow condensate to flow along the inner wall surface of the condensation duct 46 through the condensate supply nozzle 48. And then removed, only the dried air is circulated along the drying duct 40 to achieve dehumidification.

Of course, the condensed water introduced into the condensation duct 46 is introduced into the lower portion of the tub 10, and then discharged to the outside through the drain pump 14.

As described above, in addition to supplying hot air into the drum 20 by the drying heater 42 and the blowing fan 44, air is exhausted into the drum 20 by the drain pump 14. It is also possible to generate a forced flow inside the drum 20 through a variety of configurations and operations, such as to make the deodorizing action while the air in the drum 20 is exhausted.

Next, in the third step, when the hot air supply is completed in the second step, steam is injected into the drum 20 for a second predetermined time in the drum 20 to be adsorbed to the object.

In more detail, when the steam is injected into the drum 20, the steam generator 50 is operated, and the water supply valve 52 is opened to supply water from the water supply passage 12a. The heater is operated to generate steam, and then the discharge valve 54 is opened while steam is injected into the drum 20 along the injection nozzle 56.

At this time, as the drum 20 is rotated, the lift 22 pulls up and drops the object. Accordingly, the objects are mixed with each other, and steam is evenly adsorbed to the object, while hot steam is adsorbed to the object, thereby causing odor factors and water solubility. The time is melted and additionally given by the steam sterilization function.

Next, in the fourth step, when the steam injection is completed in the third step, deodorization and dehumidification are performed while hot air is gradually supplied to the inside of the drum 20 for a third set time. )

Similarly, the process of deodorization and dehumidification while the hot air is supplied into the drum 20 is the same as the second step, and thus the detailed description thereof will be omitted, but the steam adsorbed on the object and the odor factor and water-soluble time contained therein are hot air. It is to be exhausted from the drum 20, and further ironing function due to steam and hot air.

At this time, hot air having a low temperature is supplied to the drum 20 step by step, and lowering the current supplied to the drying heater 42 to reduce the calorific value of the drying heater 42 or the blowing fan 44 By lowering the current supplied to the) can also be adjusted to reduce the blowing amount of the blowing fan 44, as a result is sufficient dehumidification / drying is achieved and at the same time has the effect of reducing the electricity consumption.

Of course, it is more preferable to adjust the heat generation amount of the drying heater 42 to be reduced at set time intervals so that the energy saving efficiency is more excellent.

Next, in the fifth step, when the hot air supply is completed in the fourth step, cooling is performed while supplying low temperature wind for the fourth preset time to the inside of the drum 20, and then the rotation of the drum 20 is stopped. The object is withdrawn from the drum 20 (see S6 and S7).

In more detail, when the low temperature wind is supplied to the drum 20, the drying heater 42 is stopped while only the blower fan 44 is operated so that the tub (from the drying duct 40) is removed. 10) Only the low-temperature wind is supplied to the inside, and forced flow is generated inside the tub 10 and the drum 20, and cooled by heat exchange with the hot object, and then exhausted.

At this time, the air cooling the object of high temperature in the drum 20 may be introduced into the condensation duct 46 and recycled, but may be discharged to the outside through a separate hole.

Of course, as the drum 20 rotates, the lift 22 also lifts the object and drops it from the upper side, so that the object is evenly mixed and cooled faster by the low-temperature wind supplied from the outside. When the drum 10 is completely stopped, the cooled object can be safely taken out.

In the above, the present invention has been described in detail by taking a washing / drying drum washing machine as an example based on the embodiments of the present invention and the accompanying drawings.
