The cooling water supply mechanism 74 is connected to the fourth cold water valve 22D through the fourth cold water hose 24D to remove moisture by condensing the humid air introduced into the condensation duct 72B with the cooling water to cool the water. Will be supplied.

The drying heater 76 is an electrothermal heater installed inside the drying duct 72A to heat the low temperature and low humidity air introduced from the condensation duct 72B to the high temperature and low humidity air.

The blower 78 sucks the condensed air of the condensation duct 72B and blows the air condensed by the drying heater 76 to dry the air in the air flow direction in the drying duct 72A. It is installed behind the heater 76.

In the drying apparatus 70 and the tub 12 as described above, the operation of the drying heater 76 and the blower 78 is smoothly controlled so that the drying performance of the laundry can be improved by a plurality of temperature sensors 80 ( 82 and 84 are installed.

The temperature detection value of the first temperature sensor 80 and the second temperature sensor 82 as described above is used to measure the dryness of the laundry during drying.

The third temperature sensor 84 detects the temperature of the air heated by the drying heater 76 to prevent damage to the laundry due to overheating of the drying heater 76 during drying.

Looking at the washing method of the combined dry washing machine according to the present invention configured as described above are as follows.

First, when laundry is introduced into the drum 14 through the laundry inlet 8A and a proper amount of detergent is added to the detergent supply mechanism 26, the laundry inlet 8A is sealed by the door 10. Drying washing machine 1 is to be operated.

At this time, the combined-use washing machine 1 determines a washing course, water level, washing time, etc. according to the quantity of laundry put into the drum 14.

Then, the water supply valve assembly 22 of the water supply device 20 is opened so that the wash water is supplied to the water supply level through the water supply hose 24 into the tub 12.

That is, when the first and second cold water valves 22A and 22B of the water supply valve assembly 22 are opened, the cold water is supplied to the inside of the tub 12 through the first and second cold water hoses 24A and 24B. When the hot water valve 22E of the water supply valve assembly 22 is opened, hot water is supplied to the inside of the tub 12 through the hot water hose 24E.

At this time, the detergent introduced into the detergent supply mechanism 26 is washed down into the tub 12 by cold water or hot water supplied from the water supply valve assembly 22 to the tub 12.

When the wash water reaches the water supply level inside the tub 12, the water supply valve assembly 22 is closed to stop the water supply to the tub 12, and the drum 14 is rotated by the motor 6. The laundry is washed.

Then, when the washing stroke of the laundry is completed, the drain pump 32 is operated to wash the water in the tub 8 to the outside through the drain hose 34, the drum 14 to the motor (6) The laundry is dehydrated while being rotated at a high speed.

When the dehydration of the laundry is completed, clean laundry water is again supplied to the inside of the tub 8 to the rinsing level, and then the drum 14 is inverted left and right to rinse the laundry, and when the rinsing of the laundry is completed, The wash water is drained again.

This rinsing stroke is repeatedly performed up to a predetermined number of times.

When the rinsing stroke of the laundry is completed, the drum 14 is rotated at a high speed to completely dehydrate the water contained in the laundry.

When the dehydration process of the laundry is completed, dry hot air is supplied to the inside of the tub 12 by the drying apparatus 70 to dry the laundry.

That is, as the drying heater 76 and the blower 78 are driven, air heated by the drying heater 76 is blown by the blower 78 and blown into the tub 12 along the drying duct 72A. do.

The hot air supplied into the tub 12 as described above flows into the laundry through the inlet and the through hole 14A of the drum 14 to dry the laundry, and the humid air drying the laundry is used to dry the laundry. It flows into the tub 12 through the through hole 14A and flows into the condensation duct 72B connected to the rear surface of the tub 12.

The humid air introduced into the condensation duct 72B is condensed into low temperature and low humidity air in which moisture is removed by contacting the cooling water supplied by the cooling water supply mechanism 74, and the low temperature and low humidity air is blown by the blower 78. It flows into the drying duct 72A and is heated again by the drying heater 76.

The above process is continued until the drying of the laundry is completed, the drying of the laundry is determined by the difference between the temperature detection value detected by the first temperature sensor 80 and the second temperature sensor 82. . That is, when the difference between the temperature detection value of the first temperature sensor 80 and the second temperature sensor 82 is greater than or equal to a predetermined value, it is determined that the laundry is dried to a desired level, and the operation of the drying apparatus 70 Is stopped.

Figure 4 is an operating state diagram showing a dry washing machine when steam washing or steam rinsing according to the present invention, Figure 5 is a flow chart illustrating a washing method of a dry washing machine according to the present invention.

Looking at the steam washing or steam rinsing of the washing method of the present invention in detail with reference to FIGS. 4 and 5 as follows.

First, when the steam washing or steam rinsing is set by the consumer during the operation of the combined use washing machine 1, the washing water is supplied to the inside of the tub 12 to a predetermined level, and then the drum 14 is connected to the motor 6. By the left and right reverse at a low speed by the steam is supplied to the inside of the tub 12 by the steam generator 40 is steam washing or steam rinsing is performed. (See S1)

That is, during steam washing or steam rinsing of the combined-use washing machine 1, the third cold water valve 22C of the water supply valve assembly 22 is opened, and the third cold water hose 22C of the third cold water valve 22C is opened. Cold water flows along the 24C) to the steam generator 40 and is stored therein through the water supply port 52 of the steam generator 40.

As the steam water is supplied into the steam generator 40 as described above, the water level of the steam water is sensed by the water level sensor 48.

That is, the water level sensor 48 detects the voltage between the first and second electrodes 48A and 48B and the third electrode 48C to detect the water supply level of steam water. If at least one of the voltages between the 48A) 48B and the third electrode 48C is detected to be larger than the set voltage, it is determined that the water level of the steam water is lower than the maximum level for generating steam, and the water supply of the steam water continues. When the voltages between the first and second electrodes 48A, 48B and the third electrode 48C are all less than the set voltage, it is determined that the level of steam water has reached the maximum level for generating steam. The third cold water valve 22C is shut off.

When steam water is supplied to the inside of the steam generator 40 to an appropriate level, power is applied to the steam heater 44 of the steam generator 40 so that steam is evaporated by the steam heater 44 to steam. Is generated, and the steam is introduced into the steam supply hose 28 through the steam outlet 54 of the steam generator 40.

The steam flowing through the steam supply hose 28 is sprayed and discharged into the inlet of the tub 12 and the drum 14 through the nozzle 29 disposed inside the gasket 19 to discharge the drum 14. It will be soaked in the laundry contained inside.

Therefore, since the hot steam generated by the steam generator 40 is supplied to the inside of the tub 12 during the washing or rinsing cycle of the laundry, the internal atmosphere temperature of the tub 12 is increased to provide detergent. Activation is promoted, thereby improving laundry performance and rinsing performance of the laundry. In addition, since the hot steam is in direct contact with the laundry tumbling as the drum 14 rotates, not only the sterilization function of the laundry can be realized at any time but also the performance of the washing of the laundry is improved, thereby reducing the amount of water used.

As described above, when the steam generator 40 is driven and steam washing or steam rinsing is performed, the internal temperature of the drying duct 72A is sensed, and when the temperature detection value is higher than or equal to the set temperature, the drying apparatus 70 is operated. (See S2, S3, S4, S5)

That is, part of the steam (A) supplied to the inside of the tub 12 during the steam washing or steam rinsing flows into the drying duct (72A) of the drying apparatus 70, the interior of the drying duct (72A) The temperature is raised by the hot steam A.

At this time, the internal temperature change of the drying duct 72A is sensed by the third temperature sensor 86 installed in the drying duct 72A, and the temperature sensing value of the third temperature sensor 86 rises above the set temperature. When the drying heater 76 of the drying apparatus 70 is stopped, only the blowing fan 78 is driven.

When the blower fan 78 of the drying apparatus 70 is driven as described above, air B is discharged into the tub 12 through the drying duct 72A, and thus flows into the drying duct 72A. The steam A is discharged to the inside of the tub 12 together with the air B.

Therefore, when the steam washing or steam rinsing, the phenomenon in which the steam supplied into the tub 12 by the steam generator 40 is prevented from flowing into the drying duct 72A is prevented. Since the loss of the supplied steam is prevented, the efficiency of steam washing and steam rinsing is improved, and the interior of the drying duct 72A is moistened by the steam A so that the drying duct 72A, the drying heater 76 and the blower ( Water condensation on 78) is also prevented.

In addition, the air B is discharged into the tub 12 through the drying duct 72A of the drying apparatus 70, and the internal air C of the tub 12 is sucked through the condensation duct 72B. Therefore, the air in the tub 12 and the drum 14 flows from the front to the rear to improve the kinetic energy of steam, and the steam is evenly sprayed inside the drum 12.

The drying device 70 as described above may be driven at the same time as the steam generator 40 is driven, in this case, the steam is cooled due to the low internal temperature of the drying device 70 when steam washing and steam rinsing Since the effect of steam is reduced, it is preferable to drive after the internal temperature of the drying apparatus 70 is raised to the set temperature.

Meanwhile, when the steam generator 40 is temporarily stopped during the steam washing and steam rinsing, the blower fan 78 of the drying device 70 is also stopped, and the steam generator 40 is again When driven, the blowing fan 78 of the drying apparatus 70 is also driven again. (See S6 and S7.)

Such a blower 78 may be continuously driven when the steam generator 40 is driven, but it is preferably driven while repeating the operation and stop intermittently.

That is, when the steam generator 40 is driven to supply steam to the tub 12, the power supplied to the blower 78 is repeatedly turned on / off to operate the blower 78. If the stop and repeat is repeated, the power consumption of the drying apparatus 70 is greatly reduced compared to the method of driving continuously.

In the same manner as above, the steam washing and the steam rinsing are performed until the set time, and when the running time is longer than the set time, the process ends or enters the next stroke.

As described above, the washing method of the combined-use washing machine according to the present invention has been described with reference to the illustrated drawings. Of course, variations are possible.

That is, when the steam generator is driven during steam washing or steam rinsing, not only the blower of the drying apparatus but also the drying heater may be operated together.

In the washing method of the combined dry washing machine according to the present invention configured as described above, when steam is supplied to the inside of the washing tank by the steam generator during steam washing or steam rinsing, the drying apparatus is driven to discharge the steam introduced into the tub. The loss of steam supplied to the tub by the steam generator is prevented to improve the steam efficiency of the steam generator, there is an advantage that the performance of steam washing and steam rinsing is improved.

In addition, since the kinetic energy of steam is increased due to the air discharged into the washing tank from the drying apparatus, the steam is evenly sprayed up to the deep position of the washing tank.

In addition, since the internal environment of the drying apparatus is prevented from being wetted by the steam of the steam generator or water condensation occurs inside the drying apparatus, the possibility of corrosion occurring in the parts of the drying apparatus is reduced, and the durability of the drying apparatus is reduced. And the service life is improved, there is an advantage that the malfunction and safety accidents due to corrosion of the drying apparatus is prevented.

In addition, since the drying apparatus may maintain a dry internal environment during steam washing or steam rinsing, when the drying apparatus enters a drying stroke after steam washing or steam rinsing, drying is performed by moisture and water present in the drying apparatus.
