One side of the main body 1 is provided with a water supply port 18 to which the condensate pipe 17 is connected to supply the cold water into the condensation duct 16 so that the air circulated is condensed by the cold water.

The washing process of the conventional dry-use drum washing machine configured as described above is performed as follows.

Figure 2 is a process diagram according to the washing method of the conventional combined drying drum washing machine.

After opening the door 2 provided in the front of the main body 1, putting laundry into the drum 6 installed in the tub 3, closing the open door and selecting an operation button. At this time, the water supply valve is opened and the water to be used for washing is guided to the water supply lake (8) through the detergent container (9) to enter the tub (3). Water entered in this way is filled in the tub 3 and the drum 6 installed in the tub 3 by a predetermined height (step S101).

In this way, when the water to be used for washing is filled in the tub 3 and the drum 6 by a certain height, the water supply is stopped and the motor 4 is driven forward and backward. Since the driving force of the motor 4 is transmitted to the drum 6 through the belt 5, the drum rotates in the forward and reverse directions with a constant period. At this time, the laundry is flowed by a lift (not shown) formed on the inner circumferential surface of the drum 6, and the laundry is washed by the friction force with the drum 6 and the decomposition force of the detergent.

If the user selects the water temperature when the user selects the operation button for washing, when the water to be used for washing is watered, the washing heater 12 installed in the inner lower portion of the tub 3 operates to generate heat.

Therefore, the water used for washing is drained to the outside through the drain hose 11 (step S103). When the drainage is completed, the rinsing stroke proceeds by the same action as the preset washing stroke.

Then, after the rinsing cycle is repeated a predetermined number of times, the motor 4 is driven in one direction, and the drum 6 installed in the tub 3 receives this one-way driving force, and rotates at high speed, whereby the water contained in the laundry The dehydration stroke is completed by exiting by centrifugal force.

In this manner, when the dehydration operation is completed, the drum 6 rotates in the forward and reverse directions in the same manner as in the washing operation to move the laundry, and the blowing fan 13 operates to generate wind. The generated wind is guided through the blowing duct 14 connecting the blowing fan and the gasket 7 to enter the tub 3 and the drum 6. At this time, since the drying heater 15 installed in the air blowing duct 14 also generates heat, the wind entering the tub 3 and the drum 6 is heated and thus the moisture of the laundry is removed by the hot wind. The drying stroke is dried.

However, the conventional washing machine that proceeds the washing administration has the following problems.

Conventional drum washing machines are decontaminated by the dropping motion of clothes and detergents. However, since it is difficult to obtain desired washing performance only by such an operation, a washing heater is mounted and washing is performed by raising the water temperature. Therefore, the conventional drum washing machine is driving the washing heater to increase the water temperature when the user selects the water temperature, the washing heater has to increase the power consumption because the water to be heated.

Therefore, the user avoids the use of hot water due to a lot of power consumption, which results in a decrease in washing performance.

Accordingly, an object of the present invention is to provide a washing method of a combined drum washing machine which can improve washing performance and reduce power consumption.

In addition, a blower fan 113 is installed at an upper portion of the main body 101, and the blower fan 113 and the gasket 7 have winds generated by the blower fan 113 and the tub 103 and the drum 106. It is connected by the blow duct 114 to guide the inside. In the blowing duct 114, a drying heater 115 is installed to heat the blown wind. The lower side of one side of the blowing fan 113 and the tub 103 is connected by the condensation duct 116 to serve as a circulation passage of the wind. One side of the main body 101 is provided with a water supply port 118 connected to the condensate pipe 117 so that the air circulated by supplying cold water into the condensation duct 116 is condensed by the cold water.

Next will be described the process of performing the laundry administration in the combined drying drum washing machine according to the present invention.

4 is a process diagram of a laundry administration according to a first embodiment of the present invention.

After opening the door 102 provided in the front of the main body 101, putting laundry into the drum 106 installed in the tub 103, closing the open door and selecting an operation button. At this time, the water supply valve is opened and the water to be used for washing is guided to the water supply lake 108 through the detergent container 109 and enters the tub 103. Water entered in this way is filled in the tub 103 and the drum 106 installed in the tub 103 by a certain height (step S1).

The step S1 is water supply to the water level of H1 as shown in FIG. That is, the water level of the H1 is such that the lower level of the saser drum is slightly locked so that the detergent liquid penetrates the clothes when the clothes fall during the forward and reverse rotation of the drum.

In this way, when the water to be used for washing is filled in the tub 103 and the drum 106 by a certain height, the water supply is stopped and the motor 104 is driven forward and backward. Since the driving force of the motor 104 is transmitted to the drum 106 through the belt 105, the drum rotates in the forward and reverse directions with a predetermined period. At this time, the laundry is flowed by a lift (not shown) formed on the inner circumferential surface of the drum 106, the laundry is washed by the friction force with the drum 106 and the decomposition force of the detergent (step S2).

Since the step S2 performs cold water washing, the washing heater 112 is controlled to the off state.

When the washing stroke is completed for the time set by the above action, the drain valve 110 installed in the drain hose 111 is operated. Therefore, the water used for washing is drained to the outside through the drain hose 111 (step S3).

By operating the drainage pump in the drainage process by the step S3 and at the same time to detect the water level through a water level sensor (not shown). And if it is determined that the water level is below a certain level (H2 level in Fig. 3), the drainage is stopped.

When the drainage by the step S3 is completed, the steam washing stroke proceeds before the dehydration and rinsing stroke (S4 step).

The steam washing stroke according to the step S4 controls the drying heater 115 on / off while rotating the drum 106 forward and backward. Then, the blower fan 113 is operated. In order to prevent the laundry in the drum 106 from drying, the condensed water supply valve is controlled to be in an off state.

Therefore, immediately after the drainage is completed in step S3, the laundry inside the drum 106 is in a state containing water and a detergent solution. When the air warmed by the drying heater 115 is supplied into the drum 106 by the blowing fan 113 in this state, the temperature of the laundry in the state containing water and detergent solution is increased. At this time, the detergent added to the laundry is very active to remove the contamination of the laundry.

As a result, immediately after the draining of the step S3, the laundry inside the drum 106 is in a state of dehydration and rinsing. Therefore, the laundry is in a state in which a detergent solution and water are contained, and the drum 106 is in a state in which almost no water is used for washing. Therefore, when the laundry containing detergent solution and water is supplied with hot air, the temperature rises rapidly, and the decontamination proceeds very quickly as the detergent solution added to the laundry becomes active.

In the steam washing stroke according to step S4, the condensed water supply valve is controlled to be in an off state. Thus, the circulation cycle of air as in the drying stroke is not formed, only the process of supplying hot air to the drum interior 106 is performed, so that the laundry is not dried.

When the steam washing stroke is completed in this manner, a predetermined rinsing stroke is performed according to dehydration, water supply, and forward and reverse rotation of the drum as in the related art. In addition, after the steam washing administration is completed, the process of discharging the contamination dropped to the outside of the laundry by the high-speed dehydration may be added. That is, the drum is controlled at high speed. Therefore, after raising the driving force of the motor 111 is completely separated from the laundry to be discharged to the outside, the rinsing stroke using water as in the prior art.

After the rinsing cycle is repeated a set number of times, the motor 104 is driven in one direction, and the drum 106 installed in the tub 103 is subjected to this one-way driving force to rotate at a high speed, whereby the water contained in the laundry is centrifugal. Dehydration administration is completed by exiting.

In this manner, when the dehydration operation is completed, the drum 106 rotates in the forward and reverse directions in the same manner as in the washing operation to move the laundry, and the blowing fan 113 operates to generate wind. The generated wind is guided through the blowing duct 114 connecting the blowing fan and the gasket 107 to enter the tub 103 and the drum 106. At this time, since the drying heater 115 installed in the air blowing duct 114 also generates heat, the wind entering the tub 103 and the drum 106 is heated, and thus the moisture of the laundry is removed by the hot wind. The drying stroke is dried. At this time, while the condensate water supply valve is turned on, the circulation cycle of the air is controlled.

Next, Figure 5 is a process diagram showing a washing method of a combined drum washing machine according to a second embodiment of the present invention.

The second embodiment of the present invention is to perform the warm water washing step S2 in order to further improve the washing performance than the first embodiment.

That is, when the user selects the water temperature at the time of selecting the operation button for washing, when the water to be used for the washing water is supplied, the washing heater 112 installed in the inner lower portion of the tub 103 operates to generate heat. The heat generated in this way warms the water in the drum 106 to a selected temperature to boil the laundry.

In this way, when the water to be used for washing is filled in the tub 103 and the drum 106 by a certain height, the water supply is stopped and the motor 104 is driven forward and backward. Since the driving force of the motor 104 is transmitted to the drum 106 through the belt 105, the drum rotates in the forward and reverse directions with a predetermined period. At this time, the laundry is flowed by the lift (not shown) formed on the inner circumferential surface of the drum 106, the laundry is washed by the friction force with the drum 106 and the decomposition force of the detergent.

Therefore, in the step S2 of the present invention, unlike the first embodiment, the laundry heater 112 is heated on / off while warming the laundry.

In addition, since the steps performed in the other laundry administration process are the same as in the first embodiment, description thereof is omitted.

And while the embodiment of the present invention has been described as an example of a dry drum washing machine as an example, if a washing machine capable of supplying hot air can be applied to any washing machine.

As described above, the present invention has a basic technical idea to include a steam washing stroke to increase the temperature of the laundry by injecting hot air in the state where water and detergent solution are mixed with the laundry in the washing process of the dry-use drum washing machine.

And within the scope of the technical idea of the present invention, of course, various modifications are possible to those skilled in the art.

The present invention described above has the following effects.

First, the present invention is a time to reach a predetermined temperature by increasing the temperature of the laundry by injecting hot air into the laundry containing water and detergent solution that was used to warm the water used for washing using a conventional laundry heater This can be done quickly to reduce the washing time.

Second, the present invention does not heat the water used for washing, but increases the temperature of the laundry containing the water, thereby achieving the effect of reducing the power consumption while increasing the time to reach a predetermined temperature.

Third, the present invention increases the temperature of the laundry in which the water and detergent solution are in a state so that the detergent solution becomes active very quickly, thus making it easier to remove contamination.

Fourth, from this point, the washing performance can be improved, and the satisfaction and reliability of the product can be expected.
