DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a laundry processing apparatus and a control method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a laundry processing apparatus according to the present invention.

As shown in FIG. 1, the laundry processing apparatus includes a single set including a first laundry processing apparatus 100 and a second laundry processing apparatus 200. As shown in the drawing, the first and second laundry processing apparatuses 100 and 200 have independent structures and are combined to form the laundry processing apparatus. Further, as shown, the second laundry processing apparatus 200 may be provided in a pedestal form in another, in which case the laundry processing apparatus may have a more compact form do. On the other hand, although not shown, the first and second laundry processing apparatuses 100 and 200 may be designed to have a similar size to each other so as to be identical in design with each other.

The first and second laundry processing apparatuses 100 and 200 may be basically any one of a washing machine, a dryer, and a washing machine having a drying function. The first and second laundry processing apparatuses 100 and 200 have housings 110 and 210 which form a common outer shape. In the case of the first laundry processing apparatus 100, the doors 120 are installed in the housings 110 so that the laundry can be inserted into the housings 110, while the second laundry processing apparatus 200, which is in the form of a pedestal, The drawer 220 is provided in the housing 210 so that the laundry can be drawn into the laundry. In addition, in order to instruct the operation, a control panel 130 is provided in the housing 110. More specifically, when the first or second laundry processing apparatuses 100 and 200 are formed of a washing machine, a tub is installed in the housings 110 and 210 to store washing water, and a drum is disposed in the tub And is rotatably installed. Further, a driving mechanism for rotating the drum is provided in the housing 110, 210. If the first or second laundry processing apparatuses 100 and 200 are made of a washing machine having a drying function, a duct and a heating device are provided in the housings 110 and 210 to supply hot air into the drum in addition to the above- . Meanwhile, when the first or second laundry processing apparatuses 100 and 200 are made of a dryer, the drum is rotatably installed in the housings 110 and 210 to receive and dry the laundry. Further, a heating device and a duct structure are provided to supply hot air into the drum. Since the second laundry processing apparatus 200 has a relatively small internal space as compared with the first laundry processing apparatus 100, the components of the washing machine having the above-described washing machine, dryer, or drying function are reduced in size Is provided in the space inside the drawer 220 of the second laundry processing apparatus 200. Although the first and second laundry processing apparatuses 100 and 200 may have separate control apparatuses, the first and second laundry processing apparatuses 100 and 200 may be controlled independently of each other in order to simplify the structure and reduce the production cost. It may have a control device. Such a single control device may be installed in any one of the first and second laundry processing apparatuses 100 and 200.

Also, as shown in the figure, the first and second laundry processing apparatuses 100 and 200 may be disposed side by side. Accordingly, the user can easily access the first and second laundry processing apparatuses 100 and 200, and accordingly, the laundry processing apparatus can be conveniently used. Meanwhile, for the convenience of the user, the first and second laundry processing apparatuses 100 and 200 may be arranged vertically. That is, one of the first and second waste treatment apparatuses 100 and 200 may be mounted on the upper portion of the first and second waste treatment apparatuses 100 and 200. FIG. 1 shows a combination of the first laundry processing apparatus 100 and the second laundry processing apparatus 200. Referring to FIG.

In such a laundry processing apparatus, the first and second laundry processing apparatuses 100 and 200 are often operated together. However, such a laundry processing apparatus constitutes substantially one system, so that a limited power is supplied thereto. Therefore, if the first and second laundry processing apparatuses 100 and 200 are driven together, the power used may exceed this supply power, in which case the laundry processing apparatus can not operate properly, It can be broken. In particular, the first and second laundry processing apparatuses 100 and 200 commonly have a heater, which consumes the most power when compared with other components. When the first or second laundry processing apparatuses 100 and 200 are a washing machine, at least a heater for heating washing water is provided. In the case of a dryer, a heater for heating the air to generate hot air for drying is provided. That is, the first and second laundry processing apparatuses 100 and 200 have substantially the first and second heaters, respectively. If the first and second heaters operate simultaneously, It can easily be exceeded. Accordingly, in the laundry processing apparatus, when the first and second laundry processing apparatuses 100 and 200 are operated together, the first and second laundry processing apparatuses 100 and 200 control the first and second heaters, respectively, So that it is necessary to appropriately control the use power. Such a laundry processing apparatus for controlling power usage and a control method thereof will be described below with reference to the related drawings.

2 is a flowchart showing a control method of the laundry processing apparatus according to the present invention.

When the laundry processing apparatus is operated together, the laundry to be treated is loaded into the first laundry processing apparatus 100 and the second laundry processing apparatus 200 installed adjacent to the first laundry processing apparatus, respectively (S10) .

After the input step S10, the user instructs the first and second laundry processing apparatuses to operate using the control panels 130 and 230 provided to the user. (S20) In this indicating step S20, Can simultaneously instruct the first and second laundry processing apparatuses 100 and 200 to operate simultaneously. That is, the first and second laundry processing apparatuses 100 and 200 start operating simultaneously. On the other hand, for various reasons, the user may instruct the first and second laundry processing apparatuses 100 and 200 to operate first, and then, after a predetermined time, instruct the other one to operate. That is, the starting points of operation of the first and second laundry processing apparatuses 100 and 200 may be different from each other.

In consideration of the set operating conditions, the control device of the laundry processing apparatus may include a first heater installed in the first laundry processing apparatus 100 and a second heater installed in the second laundry processing apparatus 200, And determines a ranking (S30). As mentioned above, among the various components of the laundry processing apparatus, the first and second heaters are the biggest factors in the increase in the electric power used. Accordingly, in order for the used power to be formed within the predetermined power supply range, only one of the first and second heaters is operated during the operation of the first and second laundry processing apparatuses 100 and 200 need. In this case, in order for the laundry processing apparatus to operate efficiently, it is important to give priority to any of the first and second heaters.

More specifically, in the determining step (S30), the controller first compares the set operating condition of the first laundry processing apparatus with the operating condition of the second laundry processing apparatus. Thereafter, based on the result of the comparison, the control device selects the heater to be operated first among the first and second heaters. In the comparison step, the control device determines the amount of laundry to be processed in the first and second laundry processing apparatuses, the set operation times of the first and second laundry processing apparatuses, the set driving cycles of the first and second laundry processing apparatuses Can be compared with each other. Further, the control device may compare the required power quantities of the first and second heaters, and the target heating temperatures of the first and second heaters with each other. Determining whether to give a heater with a parameter in any of the parameters thus compared to each other can be varied depending on the operating algorithm. Nevertheless, when the user sets a detailed operating condition such as an operating time or a driving course in only one of the first and second laundry processing apparatuses, the user can select the corresponding laundry processing apparatus, It is preferable that the heater of the laundry processing apparatus in which the time or driving course is set is determined to be operated first. When the operation time of any one of the first and second laundry processing apparatuses is smaller than the other operation time, it is preferable that the heater of the laundry processing apparatus having a small operation time is determined to be operated first, Which is desirable for operation. In addition, the control panel and the control device may be provided with an option to allow the user to select the operation order of the first and second laundry processing apparatuses, 2 The operating sequence of the heater can be determined.

After the determining step S30, the controller operates the determined heater first. Thereafter, as described above, the control device selectively operates only one of the first and second heaters so that at least the used power is not exceeded (S40). In this optional operation step S40, the selective operation of the first and second heaters is effected according to predetermined operation modes, for efficient and efficient operation of the laundry processing apparatus. Also, as described above, with respect to the indicating step, the first and second laundry processing apparatuses 100 and 200 may be operated simultaneously or may be operated with a time difference of a predetermined period. In each of these cases, The operating steps, and more precisely the operating modes, can be different from each other. FIG. 3 shows an operation mode when the first and second laundry processing apparatuses 100 and 200 start operating simultaneously. Referring to FIG. 3, a corresponding operation mode will be described below.

The operation mode P shown in FIG. 3 shows a driving sequence in which the heater is operated when the first laundry processing apparatus 100 and the second laundry processing apparatus 200 operate simultaneously. When the first and second laundry processing apparatuses 100 and 200 are operated simultaneously, the first and second heaters provided to the first and second laundry processing apparatuses 100 and 200 are not operated. Therefore, the operation mode P in Fig. 3 is actually applied to a state in which the first and second heaters are not operated. If the first and second laundry processing apparatuses 100 and 200 are not operated at the same time and the first and second laundry processing apparatuses 100 and 200 start at a predetermined time difference, The following laundry processing apparatus can be started before the heater is operated. Even in this case, since the first and second heaters are still not operated, the operation mode P according to FIG. 3 can be applied.

In both the operation mode P of FIG. 3 and the operation mode Q of FIG. 4 described later, the operation step S40 is basically the same as the operation of the first heater of the first laundry processing apparatus 100 And a second heating step of driving a second heater of the second laundry processing apparatus 200 separately operated from the first heater. More specifically, in the first and / or second heating step, when the first and / or second laundry processing apparatuses 100 and 200 are made of a washing machine, the washing water in the tub is supplied to the first and / Heating the air supplied into the drum using the first and / or second heaters when the first and / or second laundry processing apparatuses 100 and 200 are made of a dryer, . That is, commonly, the first and second heating steps refer to a step of heating the objects to be heated, i.e., the washing water or the drying air, using the first and second heaters.

3, M denotes operation of the first heater of the first laundry processing apparatus 100, S denotes a second operation mode of the second laundry processing apparatus 200, It means to operate the heater. The subscript if signifies a step in which the heater starts to be operated and the heating object is heated until it reaches a predetermined temperature and then turned off. Also, the subscript i means the step of starting the operation of the heater, and f means the step of ending the operation of the heater. In the case of the subscripts, it means that the operation of the heater is in progress.

If it is determined that the first heater is operated first in the determining step S30, the operation modes P1 to P4 may be such that the first heater determined in the determining step S30 in the operating step S40 is operated first Respectively. In addition, the operation modes P5 to P8 indicate that the second heater is operated first in the operation step (S40) when it is determined that the second heater is operated first in the determination step (S30).

First, in the operation mode P1, after the first heater starts operating and the heating object of the first laundry processing apparatus 100 is heated up to the first set temperature and then terminated (M _if ), the second heater starts to operate (S _if ) after heating the object to be heated of the second laundry processing apparatus 200 to the second set temperature.

The operation mode P2 is temporarily stopped after a predetermined time elapses after the first heater starts operating (M _i ) first. Thereafter, the second heater starts to be operated, and the heating object of the second laundry processing apparatus 200 is heated to the second set temperature and then terminated (S _if ). Thereafter, the first heater again heats the object to be heated of the first laundry processing apparatus 100 to the first set temperature, and then the operation is terminated (M _f ).

After the first heater starts to operate (M _i ), the operation mode P 3 is temporarily stopped after a predetermined time elapses, and the second heater starts to operate (S _i ). After a certain time elapses, the operation of the second heater is temporarily stopped, and the operation is terminated after the first heater heats the object to be heated of the first laundry processing apparatus 100 to the first set temperature ( _Mf ). After completion of the operation of the first heater, the second heater heats the object to be heated of the second laundry processing apparatus 200 to the second set temperature, and then the operation is terminated (S _f ).

After the first heater starts operating (M _i ), the operation mode P 4 is temporarily stopped after a certain time has elapsed, and the second heater starts to operate (S _i ). Thereafter, the operation of the second heater is temporarily stopped again, and the first heater is again operated (M). Thereafter, the operation of the first heater is temporarily terminated again, and the second heater heats the object to be heated of the second laundry processing apparatus 200 to the second set temperature (S _f ). Next, the first heater heats the object to be heated of the first laundry processing apparatus 100 to the first set temperature, and then the operation is terminated (M _f ).

On the other hand, the operation modes P5, P6, P7 and P8 are similar to the operation modes P1, P2, P3 and P4. However, since the second heater is determined to be operated first in the determining step S30, only the sequence of operating the first heater and the second heater, that is, only M and S are exchanged. For example, in the operation mode P5, after the second heater starts to be operated first and the object to be heated of the second laundry processing apparatus 200 is raised to the second set temperature and then terminated (S _if ), the first heater (M _if ) after the heating object of the first laundry processing apparatus 100 is started to be operated and raised to the first set temperature.

As a result, in the operation mode P1 or the operation mode P5, the remaining steps are performed after either the first heating step or the second heating step is completely performed, that is, the heating object is heated up to a predetermined temperature. That is, in accordance with the operation mode P1 or P5, the operation step S40 is repeated until one of the first heater and the second heater, which is determined in the determining step, is continuously . In addition, after the operation of the determined heater, the operation step (S40) includes operating the other of the first heater and the second heater until the object to be heated is heated to a predetermined temperature.

Also, as in the operation modes P3 to P4 or the operation modes P7 to P8, the first heating step and the second heating step may be performed when the heating objects of the first and second laundry processing apparatuses 100, Can be carried out alternately until reaching. That is, according to the operation modes P3 to P4 or the operation modes P7 to P8, the operation step S40 first operates the heater determined in the determination step for a predetermined time, and then the corresponding objects are heated to predetermined temperatures And alternately operating the first and second heaters for a predetermined period of time. In the alternate operation of the first and second heaters in this operation step (S40), the operating time of each of the first and second heaters may be appropriately changed. That is, the operating times of the first and second heaters may be identical to each other, but may be set differently in consideration of the set operating conditions.

Meanwhile, FIG. 4 shows the operation mode when the first and second laundry processing apparatuses 100 and 200 start to operate at a predetermined time interval, and a corresponding operation mode will be described with reference to FIG.

The operation mode Q shown in FIG. 4 is a mode in which when one of the first laundry processing apparatus 100 and the second laundry processing apparatus 200 starts operating the other one of the first laundry processing apparatus 100 and the second laundry processing apparatus 200, The procedure for driving the second heater will be described. As described above, even if the first and second laundry processing apparatuses 100 and 200 start at a predetermined time difference, the following laundry processing apparatuses start to operate before the heater of the laundry processing apparatus started earlier is activated . In this case, since the first and second heaters are still not operated, the operation mode P according to FIG. 3 is applied. Accordingly, the operation mode Q according to FIG. 4 can be applied when the first and second laundry processing apparatuses 100 and 200 start operating with a time lag, and one of the heaters is already operating. In this case, according to the determination of the determination step S30 performed previously, the control device may stop the operation of the heater while it is in operation, and may continuously operate the heater.

4, M denotes the operation of the first heater of the first laundry processing apparatus 100, S denotes the second operation mode of the second laundry processing apparatus 200, It means to operate the heater. The subscript if signifies a step in which the heater starts to be operated and the heating object is heated until it reaches a predetermined temperature and then turned off. Also, the subscript i means the step of starting the operation of the heater, and f means the step of ending the operation of the heater. Also, in the case of the subscript, it means that the operation of the heater is in progress. Finally, the subscript s means temporarily stopping the operation of the heater.

The operation mode Q1 to the operation mode Q7 mean the operation mode when the second laundry processing apparatus 200 is operated while the first laundry processing apparatus 100 is operated and the first heater is operated. In addition, the operation mode Q8 to the operation mode Q14 indicate the operation mode when the first laundry processing apparatus 100 is operated while the second laundry processing apparatus 200 is operated and the second heater is operated.

More specifically, in the operation mode Q1 to Q3, if it is determined in the determining step S30 that the second heater is operated first, the second laundry processing apparatus 200 is operated and its operation of the second heater When required, the operation of the first heater of the first laundry processing apparatus 100 which is in operation is stopped, and the operation modes of the second heater are started. That is, according to the operation mode Q1-Q3, the operation step S40 may include stopping the operated heater when a heater which is not determined in the determining step S30 among the first and second heaters is in operation, and A step of operating the heater among the first and second heaters is performed first. Also, the operation modes Q4 to Q7 may be set such that, if it is determined that the first heater is operated first in the determining step S30, even if the second laundry processing apparatus 200 starts to be newly operated, When the operation of the first heater of the heater 100 is continuously performed. That is, according to the operation mode Q4-Q7, the operation step S40 is a step of continuously operating the determined heater when the heater determined in the determining step S30 among the first and second heaters is in operation First.

More specifically, the operation modes Q1 to Q7 will be described in detail. First, in the operation mode Q1, the second laundry processing apparatus is operated while the first heater is operating first, and the second heater is operated in the determining step S30 If it is determined that the operation is first performed, the operation of the first heater is temporarily stopped (step Ms). Thereafter, the second heater starts to be operated, and the heating object of the second laundry processing apparatus 200 is heated to a second set temperature and then terminated (S _if ). Thereafter, the first heater is operated again to heat the object to be heated of the first laundry processing apparatus 100 to the first set temperature (M _f ).

In the operation mode Q2, if it is determined that the second laundry processing apparatus is operated while the first heater is first operated (Mi) and the second heater is operated first in the determining step (S30), the operation of the first heater is temporarily (Ms). Thereafter, the second heater starts to operate (S _i ). When the second heater is temporarily stopped after being operated for a predetermined time, the first heater is operated again (M). Thereafter, the driving of the first heater is temporarily stopped, and the second heater is finished after heating the object to be heated of the second laundry processing apparatus to the second set temperature (S _f ). Thereafter, the first heater terminates after heating the object to be heated of the first laundry processing apparatus 100 to the first set temperature (M _f ).

In the operation mode Q3, if it is determined that the second laundry processing apparatus is operated while the first heater is first operated (Mi) and the second heater is operated first in the determining step (S30), the operation of the first heater is temporarily (Ms). Thereafter, the second heater starts to operate (S _i ). When the second heater is temporarily stopped for a predetermined time, the first heater is operated again to raise the heating object of the first laundry processing apparatus 100 to the first set temperature (M _f ) . The second heater is then terminated after raising the heating object of the second laundry processing apparatus 200 to the second set temperature (S _f )

In the operation mode Q4, if it is determined in the determining step S30 that the first heater is operated first, even if the second laundry processing apparatus starts operating during the first heater operation (Mi) The operation of the control unit is continuously maintained. In particular, the first heater terminates after heating the object to be heated of the first laundry processing apparatus 100 to the first set temperature (M _f ). After that, the second heater starts to operate and the heating object of the second laundry processing apparatus 200 is raised to the second set temperature, and the operation is terminated (S _if ).

In the operation mode Q5, if it is determined in the determining step S30 that the first heater is operated first, even if the second laundry processing apparatus starts operating during the first heater operation (Mi) (M). ≪ / RTI > After the predetermined time has elapsed, the operation of the first heater is temporarily stopped, the second heater starts to be operated, the object to be heated of the second laundry processing apparatus 200 is raised to the second set temperature, (S _if ). After that, the first heater is operated again, and the heating object of the first laundry processing apparatus 100 is raised to the first set temperature and then terminated (M _f ).

In the operation mode Q6, if it is determined in the determining step S30 that the first heater is operated first, even if the second laundry processing apparatus starts operating during the first heater operation (Mi) (M). ≪ / RTI > After a predetermined time has elapsed, the operation of the first heater is temporarily stopped and the operation of the second heater is started (S _i ). When the predetermined time elapses after the operation of the second heater is started, the second heater is temporarily stopped and the first heater starts to heat the object to be heated of the first laundry processing apparatus 100 to the first set temperature And then the operation is terminated (M _f ). After that, the second heater raises the object to be heated of the second laundry processing apparatus 200 to the second set temperature, and then the operation ends (S _f ).

In the operation mode Q7, if it is determined in the determining step S30 that the first heater is operated first, even if the second laundry processing apparatus starts operating during the first heater operation (Mi) (M). ≪ / RTI > After a predetermined time has elapsed, the operation of the first heater is temporarily stopped and the operation of the second heater is started (S _i ). Thereafter, the operation of the second heater is temporarily stopped, and the operation of the first heater is performed (M). Thereafter, the operation of the first heater is temporarily stopped again after a predetermined time, and the second heater raises the object to be heated of the second laundry processing apparatus 200 to the second set temperature, and then the operation is terminated S _f ). Thereafter, the first heater raises the object to be heated of the first laundry processing apparatus 100 to the first set temperature, and then the operation is terminated (M _f ).

On the other hand, the operation modes Q8 to Q14 are similar to the operation modes Q1 to Q7. However, since the operation modes Q8-Q14 are the operation modes when the first laundry processing apparatus 100 is operated while the second laundry processing apparatus 200 is operated and the second heater is operated, 2 Only the sequence of operation of the heater, that is, M and S are exchanged.

As a result, in the operation step S40 according to the operation modes Q1 to Q3 and the operation modes Q8 to Q10, the operation of the heater of the laundry processing apparatus which is newly operated is stopped after the operation of the heater of the laundry processing apparatus in operation is stopped And an intermediate heating step. Here, the intermediate heating step may be S _if step in the operation mode Q1, and may be S _i step in the operation mode Q2, Q3. Also, it may be an M _if step in the operation mode Q8, and an M _i step in the operation mode Q9, Q10. Further, an additional heating step may be performed to operate the heater included in the laundry processing apparatus, which is in operation after the completion of the intermediate heating step. Here, the additional heating step is in the Q1 and can be the step M _f, M in the operation mode Q2 step, the operation mode Q3 can be an M step _f. In the operation mode Q8, it may be the step S _f , and in the operation mode Q 9, the step S, and in the step Q 10, the step S _f . That is, as shown in the operation modes Q1 to Q3 and the operation modes Q8 to Q10, the intermediate heating step and the additional heating step are repeated until the temperatures of the heating objects of the first and second laundry processing apparatuses reach preset temperatures The heating steps can be performed alternately. Therefore, in consideration of the intermediate heating step and the additional heating steps described above, the operation step S40 according to the operation modes Q1-Q3 and Q8-Q10 is performed by stopping the heater not determined in the determining step S30, And operating the first and second heaters alternately for a predetermined time until the objects to be heated are respectively heated to preset temperatures. In the alternate operation of the first and second heaters in this operation step (S40), the operating time of each of the first and second heaters may be appropriately changed. That is, the operating times of the first and second heaters may be identical to each other, but may be set differently in consideration of the set operating conditions.

In addition, the operation step S40 according to the operation modes Q4 to Q7 and the operation modes Q11 to Q14 includes a continuous heating step in which the heater provided in the laundry processing apparatus in operation is continuously operated, and a continuous heating step in which the laundry processing apparatus And an intermediate heating step of driving the heater. In this case, the continuous heating step is in the operation mode Q4 may be a step M _f, the operation mode Q5 Q7 ~ M can be a step. Also, the intermediate heating step may be S _if step in the operation mode Q4 and the operation mode Q5, and S _i step in the operation mode Q6 and the operation mode Q7. The continuous and intermediate heating steps in the operation mode Q11-Q14 are similar to the corresponding steps in the operation mode Q4-Q7 described above, except that only M and S change with each other.

In the operation modes Q4 and Q11 of the operation modes, the intermediate heating step is performed to raise the temperature of the object to be dried to the set temperature after the temperature of the object to be dried is raised to the set temperature through the continuous heating step. Therefore, in the operation step S40 according to the operation modes Q4 and Q11, when the heater determined in the determining step S30 among the first and second heaters is in operation, until the heating object is heated to a preset temperature , Continuously operating the determined heater first, and after the operating step, operating the heater of the other one of the first and second heaters until the object to be heated is heated to a predetermined temperature.
