The input unit 203, the display panel 204, and the detergent supply unit 205 are interlocked with the first washing tank 301 and the second washing tank 302, and the first and second washing tanks 301 and 302 are the same. It is also possible to configure the washing tank of capacity, but it is possible to configure differently in large capacity and small capacity so as to selectively use the first and second washing tanks 301 and 302 or to drive the first and second washing tanks 301 and 302 simultaneously. do.

The input unit 203 has a power button, an operation button for starting an operation, a washing tank selection button for selecting a washing tank to be washed so that the first washing tank 301 and the second washing tank 302 can be washed simultaneously or simultaneously. The washing machine includes a course button for selecting a washing course for each washing tank, and a function button for adding / deleting individual functions. The shape of the input unit 203 is not necessarily limited thereto, and may be implemented in various forms.

The display panel 204 is implemented to individually display the washing instruction input state and the washing progress state of each washing tank.

The detergent supply unit 205 is configured to distinguish the detergent introduced into the first washing tank 301 and the detergent introduced into the second washing tank 302 from each other, it is also possible to implement a separate detergent supply for the washing tank.

2 is a cross-sectional view showing the internal configuration of a two-chamber washing machine according to the present invention, a first rotating drum 321 inside the first washing tank 301, a second rotating drum 322 inside the second washing tank 302. ) Is installed.

On one side of the outer case 301, an external water supply pipe 400 is installed to supply water necessary for washing, and water supply pipes 401 and 402 and water supply valves 411 branched from the external water supply pipe 400 to respective washing tanks. 412 is installed. When the water supply valves 411 and 412 are opened, the water supply pipes 401 and 402 supply washing water to the respective washing tanks 301 and 302 via the detergent supply unit 205.

In the washing tanks 301 and 302, driving motors 501 and 502 for rotationally driving the washing tanks are installed to simultaneously or individually drive the washing tanks using driving belts and clutches associated with the driving motors. 302 is provided with drying devices (601, 602) for drying the laundry in the washing tank, the drying devices (601, 602) are drying ducts (621, 622), drying heaters (641, 642), drying fans ( 661 and 662 and condensation ducts 681 and 682.

In addition, the washing tanks 301 and 302 are provided with washing water heaters 701 and 702 for heating the washing water, drain pipes 801 and 802 for draining the washing water, and drain pumps 821 and 822. have.

Figure 3 is a block diagram showing the configuration of a two-chamber washing machine according to the present invention, the two-chamber washing machine according to the present invention is a water supply valve for washing / dehydration / drying administration when an input command by the user is input through the input unit 203 411 and 412, driving motors 501 and 502, drying heaters 641 and 642, drying fans 661 and 662, washing water heaters 701 and 702, and drain pumps 821 and 822 to the control unit. Each device is controlled by the drive whether the washing process proceeds.

Therefore, when the user drives only one washing tank, it is possible to proceed by the normal washing operation control, but when the laundry is started by putting laundry into another washing tank while the washing process is performed in one washing tank or the user has two washing tanks. Simultaneous washing is also possible by putting laundry in the same time.

Figure 4 is a flow chart schematically showing the operation of the two-chamber washing machine according to the present invention.

First of all, when the user has a small amount of laundry, it is necessary to operate only a small capacity washing tank (first washing tank) in order to prevent unnecessary waste of electric power, so that the laundry is put into the first washing tank and only the first washing tank is operated by operating the input button. Operate. If it is determined that the amount of laundry exceeds the capacity of the first washing tank, only another large capacity washing tank (second washing tank) is operated. Of course, if the amount of laundry is considerable, if you operate both the small capacity and large capacity washing tanks (first and second washing tanks) at the same time, a large amount of laundry may be solved at once.

According to the present invention, when a washing instruction is input to the first washing tank 301, the first washing tank 301 checks whether it is a water supply condition, and if it is determined that the water supply condition is possible, water is supplied for a predetermined time set in advance.

In the case of hot water washing in which it is necessary to heat the wash water supplied to the first washing tank 301, after the washing water enters the heat administration (S200) and checks whether the wash water supplied is heated, the wash water can be heated. If it is determined that the washing water is heated to increase the temperature of the washing water to the target temperature. In the process of raising the temperature of the wash water, washing may be performed in advance, or washing may be performed after reaching the target temperature. In addition, this process can be omitted if the washing is not hot water.

On the other hand, after the washing stroke (S300) proceeds at the target temperature, when the washing stroke is completed, enter the drainage stroke (S400) to check whether it is a condition that can drain the wash water in the washing tank, and if it is determined that the drainable conditions, the drainage proceeds do.

When the drainage is completed, after entering the dehydration administration (S500) to check whether the dehydration conditions, and if it is determined that the dehydration conditions proceed with dehydration.

After that, the rinsing stroke set by the user is performed. The rinsing stroke is also performed in the water supply and driving of the washing tank and draining / dehydrating for a predetermined time.

If the process in the rinsing process is different from the washing administration, proceed with the rinsing process by the corresponding process, but if the water supply / washing water heating / drainage / dehydration stroke is completed, go to the drying administration (S600) whether the drying administration is possible After confirmation, if it is determined that a drying administration is possible, a drying administration is performed. When the construction administration is complete, complete the entire administration.

Hereinafter, a method of operating a two-chamber washing machine according to the present invention will be described in detail.

First, the process of determining the water supply possible conditions in the water supply administration checks whether the washing water is supplied to the second washing tank when the washing instruction is input to the first washing tank 301 (S100). If the washing water is being supplied to the second washing tank 302, the washing water is waited to be supplied to the first washing tank 301 until the washing water supply to the second washing tank 302 is completed. When the washing water supply to the washing tank 302 is completed, the washing water supply to the first washing tank 301 is started.

When the washing water is supplied to the first washing tank 301 under the condition that the washing water is supplied to the second washing tank 302, the amount of the washing water supplied from one external water supply pipe 400 is halved to wash the washing water for a predetermined time. Even if it is supplied, water cannot be supplied properly. Therefore, in the present invention, in the situation where the washing water is supplied to the second washing tank 302, the washing machine waits not to supply the washing water to the first washing tank 301, and when the supply of the washing water to the second washing tank 302 is completed, the first washing tank ( By supplying the washing water to the 301, the washing machine is supplied with the appropriate amount of the washing water in a predetermined time for both the first washing tank 301 and the second washing tank 302.

The present invention may be applied to a case in which the drying administration is performed in the second washing tank 302 in addition to the water supply administration in which the water supply proceeds in the second washing tank 302 in determining whether the water is supplied to the first washing tank 301. . That is, in the case of a drying system in which the condensate is injected in the drying stroke so that the condensation occurs in the condensation duct, the condensate is branched from the external water supply pipe 400 and is injected into the condensation duct, so that the amount of washing water supplied to the first washing tank 301 is maintained. Will affect. In this case, it is also possible to wait for the supply of the washing water to the first washing tank (301). However, if the amount of condensate sprayed is small, it may not be applied.

On the other hand, the water supply command to the first washing tank 301 and the water supply administration command to the second washing tank 302 may occur at the same time. In this case, it is preferable to give priority to either washing tank without any condition or give priority to a washing tank that satisfies certain conditions. That is, when a water supply administration command is input to the first washing tank 301 and the second washing tank 302 at the same time, each washing tank is not yet in the state of being supplied with water. You won't be able to decide first.

Therefore, in this case, when the priority is given to the first washing tank 301, the water supply proceeds preferentially to the first washing tank 301, and when the water supply to the first washing tank 301 is completed, the water supply to the second washing tank 302 is It is going to proceed. On the contrary, if the priority is given to the second washing tank 302, the water supply proceeds preferentially to the second washing tank 302, and when the water supply to the second washing tank 302 is completed, the water supply to the first washing tank 301 is performed. .

In addition, in addition to giving priority to any one washing tank, if the same washing administrative order is given to each washing tank at the same time, the washing administration order to the washing tank having the shortest remaining time is compared by comparing the remaining time until the final washing completion. You can also make progress. Moreover, it is also possible to directly set the rank between specific administrative orders. For example, when a water supply command is input to the first washing tank 301 and a drying command is input to the second washing tank 302, since the total washing remaining time of the second washing tank 302 remains less, In this case, the drying administration of the second washing tank 302 may be performed first without examining the total washing remaining time.

In addition, the priority setting method is similarly applied to not only the water supply administration step but also the washing water heating administration, drainage administration, dehydration administration, and drying administration described below.

And the operating conditions in the washing water heating stroke, first, when the washing water is heated in the first washing tank 301 and heats the water to a predetermined temperature into the heating stroke (S200), the washing water in the second washing tank 302 Review if it is a step. If the washing water heating administration is in progress in the second washing tank 302, the washing water in the first washing tank 301 is to wait for the heating administration. If it is determined in the second washing tank 302 that the washing water is not the heat administration step, it is determined whether the second washing tank 302 is a drying administration step.

Similarly, if the drying operation is in progress in the second washing tank 302, the washing water in the first washing tank 301 is to wait for the heat administration. If it is determined that the drying cycle is not in the second washing tank 302, the washing water in the first washing tank 301 starts a heat stroke.

Next, when the operation conditions in the drying administration (S600) is the laundry is completed in the first washing tank 301 and enters the drying administration step (S600), it is examined whether the washing water is in the heat administration phase in the second washing tank (302). do. When the washing water is heated in the second washing tank 302, the drying operation is waited in the first washing tank 301. If it is determined in the second washing tank 302 that the washing water is not the heat administration step, it is determined whether the second washing tank 302 is a drying administration step. Likewise, if the drying administration is in progress in the second washing tank 302, the drying administration in the first washing tank 301 is to be waited for. If it is determined that the drying cycle is not in the second washing tank 302, the drying administration in the first washing tank 301 is started.

As described above, the determination of whether to start the drying administration, in the case of the drying administration stage using condensed water, in addition to determining whether the washing water in the second washing tank 302 is in progress or whether the drying administration stage is in progress. The second washing tank 302 may further determine whether the water supply step is in progress.

In addition, since the washing water heating heater or the drying heater requires a lot of load, when several heaters are operated at the same time, the upper limit of the current due to overload may be exceeded, thereby preventing damage and failure of electrical components. According to the present invention, when the washing water in the second washing tank 302 is undergoing a heat stroke or a drying stroke, the washing water in the first washing tank 301 does not undergo a heat stroke, and then the washing water is heated or dried in the second washing tank 302. When the stroke is completed, the washing water of the first washing tank 301 may be guided to proceed with the heat administration, and thus the washing water heating heaters 701 and 702 or the drying heaters 641 and 642 may be prevented from operating.

Operating conditions in the washing water heating administration or drying administration, when the washing water heating administration step (S200) or drying administration step (S600) to the first washing tank 301, the washing water heating heater in the second washing tank 302 first Review if 702 is working. When the washing water heater 702 is operating in the second washing tank 302, the washing water heating heater 701 or the drying heater 641 in the first washing tank 301 is waited to be operated. If it is determined that the washing water heater 702 is not in operation in the second washing tank 302, it is determined whether the drying heater 642 of the second washing tank 302 is in operation. Likewise, when it is determined that the drying heater 642 is operating in the second washing tank 302, the washing water heating heater 701 or the drying heater 641 in the first washing tank 301 is waited. When it is determined that the drying heater 642 is not in operation in the second washing tank 302, the washing water heating heater 701 or the drying heater 641 in the first washing tank 301 is operated.

The determination of the washing water heating administration or the drying administration stage determines whether the washing water heating heater or the drying heater is in operation to determine whether it is operable. That is, even if the washing water is in the heat administration stage, the washing water heating heater does not always operate, and repeats the ON-OFF in the set temperature range. Similarly, in the drying administration stage, the drying heater repeats the ON-OFF within a predetermined temperature range with respect to the set temperature. Therefore, the washing water heating heater 701 or the drying heater 641 in the first washing tank 301 is operated only when the washing water heating heater 702 or the drying heater 642 is operating in the second washing tank 302. When the washing water heating heater 702 or the drying heater 642 of the second washing tank 302 is turned off, the washing water heating heater 701 or the drying heater 641 of the first washing tank 301 is operated. To do that.

In order for the washing water of the first washing tank 301 to proceed with the heating administration or drying administration, the washing water of the second washing tank 302 is waited until the heating administration or drying administration is completed, and the washing water of the second washing tank 302 is heated. When the stroke or drying stroke is completed, the washing water of the first washing tank 301 starts the heating stroke or the drying stroke, and only the time during which the washing water heating heater 702 or the drying heater 642 is operating in the second washing tank 302. When the wash water heating heater 702 or the drying heater 642 is turned off in the second washing tank 302, the washing water heating heater 701 or the drying heater 641 of the first washing tank 301 is operated immediately. It is possible to halve the time required for the stroke.

On the other hand, when the washing administration is completed in the first washing tank 301, it is necessary to drain the washing water inside the washing tank to check whether the drainage is in progress in the second washing tank 302 before starting the draining of the first washing tank 301. . If the drainage is in progress in the second washing tank 302, the drainage of the first washing tank 301 is waited until the drainage of the second washing tank 302 is completed, and then the drainage of the second washing tank 302 Upon completion, drainage of the first washing tank 301 is started.

When the first washing tank 301 is drained while the second washing tank 302 is draining, the amount of washing water drained to one external drain pipe 800 increases and drains for a predetermined time. Even if it is not enough drainage can not be made. Therefore, in the situation where the drainage is being progressed in the second washing tank 302, the water is waited without proceeding with the drainage of the first washing tank 301, and when the drainage of the second washing tank 302 is completed, the drainage of the first washing tank 301 is performed. By inducing the water to be discharged, sufficient drainage is made within a predetermined time for both the first washing tank 301 and the second washing tank 302.

When a dehydration administration command is input in the first washing tank 301, the second washing tank 302 checks whether dehydration is in progress. If the dehydration administration is in progress in the second washing tank 302, the dehydrating administration of the first washing tank 301 is waited until the dehydration administration of the second washing tank 302 is completed, and then the second washing tank 302 is performed. After the dehydration administration of the first washing tank 301 starts the dehydration administration.

On the other hand, when the dehydration stroke of the first washing tank 301 proceeds in the situation where the dehydration stroke is in progress in the second washing tank 302, the noise and vibration generated by the high-speed rotation of the two rotating drums overlap or cause resonance. Do not allow two rotating drums to rotate at the same time.

In the present invention, for example, a case consisting of two tanks in which two washing tanks are provided separately in the washing machine has been described as an example. However, even if the three tank washing machines are divided into different sizes, that is, large, medium, and small, if necessary, Apparently, it can be applied by those skilled in the art within the scope of the idea.
