In the odor removal mode, the driving motor 30 is operated to spin so that the objects to be removed are not mixed with each other, and at the same time, some of the odor factors are removed by centrifugal force.

Next, the drying duct 40 and the condensation duct 46 are respectively installed on the outer upper and lower ends of the tub 10, the drying duct 40 is arranged so as to be horizontally connected to the upper end of the tub 10. Is installed, the condensation duct 46 is arranged so as to be vertically connected to the lower end of one side of the tub (10).

More specifically, a drying heater 42 and a blowing fan 44 are installed in the drying duct 40 to supply and circulate hot air into the drum 20, while inside the condensation duct 46. The condensate supply nozzle 48 and a condensate water supply valve (not shown) are installed to supply condensate to remove moisture from air circulated.

Of course, the drying heater 42 and the blower fan 44 and the condensate water supply valve may be adjusted according to a washing program stored in the control board in advance or according to a control signal transmitted by the button.

For example, only the blowing fan 44 is operated to cool only by supplying low-temperature wind into the drum 20, or the drying heater 42 and the blowing fan 44 are operated to operate the drum 20. The hot hot air is supplied to the inside, or the condensate water supply valve is operated to open, and the hot air is supplied / circulated to the drum 20 while the moisture contained therein is condensed and removed by the condensate. May be made.

Next, the steam generator 50 is connected to the water supply passage 12a to receive water, and the steam generated from the steam generator 50 is injected into an upper end of the tub 10. 56 to be injected into the drum 20 through.

Of course, the injection nozzle 56 is installed so that the end thereof is installed in the tub 10, the drum 20 toward the inside.

Therefore, the laundry / dry combined drum washing machine configured as described above controls the operation of various components according to a washing program or an odor removing program pre-inputted on the control panel, and accordingly, a general washing mode, an ironing mode, a boiling mode, and a drying operation are performed. 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.

Figure 3 is a view showing an example of a method for removing the odor according to the present invention, the method for removing the odor according to the present invention is to supply hot air in the state of rotating the drum in the spinning state, or to rotate the drum in the spinning state It is made by supplying hot air while supplying steam in a state and then supplying hot air in a state of rotating the drum in a tumbling state, or by supplying steam in a state of rotating the drum in a spinning state and then supplying the hot air while rotating the drum. Preferably the process of cooling the object is followed by rotating the drum or supplying unheated wind with it.

4 is a view showing an example of a method for removing odors in a washing machine according to the present invention.

First, in the first step the object to be odor is removed to the drum 20, and then the odor removal 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 This is regulated.

Next, in the second step, the drum 20 is accelerated and rotated, so that the drums 20 are rotated for a predetermined time so that the objects to be odor removed are not mixed with each other in the state attached to the inside of the drum 20. Deodorization takes place (see S2, S3). At this time, when the driving motor 30 rotates the drum 20 to 1G or more, the object to be odor is removed as the centrifugal force is formed larger than gravity by the rotation of the drum 20 is the drum 20 Rotated in the spinning state attached to the, the smell is blown away in the radial direction to remove the smell. In addition, since the objects to be removed in the drum 20 is rotated in the state attached to each other is prevented from being mixed with each other, as a result of a relatively odor-sensitive object from the relatively strong odor object Objects that are delivered or have different odors can prevent the smells from being delivered to each other. On the other hand, hot air is supplied at least in part while the drum 20 is rotated, so that the odor can be more smoothly removed.

Next, in the third step, the drum 20 is decelerated and rotated so that steam is supplied to the inside of the drum 20 for a first set time to be adsorbed to the object (see S4 and S5). At this time, when the driving motor 30 rotates the drum 20 to 1G or less, the drum 20 is decelerated and rotated, and the objects are attracted by the lift 22 as the centrifugal force is formed smaller than gravity. After being raised, the laundry is mixed with each other while rotating in a tumbling state falling from the upper side. As such, while the drum 20 is rotated in a tumbling state, steam is injected into the drum 20. 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. Of course, the water supply valve 52 and the heater may be operated in advance to generate steam in advance, and the steam generated as described above may be discharged through the injection nozzle 56 as soon as the discharge valve 54 is opened. 20) It is sprayed inside, but only small amount of steam is sprayed to moisten the object. At this time, as the drum 20 is tumbling, the inside of the object is mixed with each other while the steam is evenly adsorbed to the object, while the hot steam is adsorbed to the object to melt the odor factor and water-soluble time, further sterilization by steam Function is also given.

Next, when the steam injection is completed in the third step in the fourth step, while the hot air is supplied to the inside of the drum 20 for a second set time, deodorization and dehumidification are performed (see S6). Of course, while the hot air is supplied into the drum 20, it is preferable that the drum 20 is rotated in a tumbling or spinning state. 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 the secondary odor is removed while being 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.

On the other hand, it is also possible to set the odor removal modes to be supplied to the steam immediately in the spinning step of S3, and then executed in the fourth step.

Next, in a fifth step, cooling is performed while supplying low temperature wind to the inside of the drum 20 for a third set time, and then the rotation of the drum 20 is stopped, and the object is withdrawn from the drum 20. (See S7, S8). 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.
