In addition, the present invention can effectively and efficiently operate the laundry treatment apparatus by operating the first and second heaters in accordance with the priority and operation modes of the first and second heaters in consideration of the set operating conditions.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the laundry treatment apparatus and control method according to the present invention.

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

As shown in FIG. 1, the laundry treatment apparatus includes a set including a first laundry treatment apparatus 100 and a second laundry treatment apparatus 200. And, as shown, the first and second laundry treatment apparatus (100,200) has a structure independent of each other and are combined to form the laundry treatment apparatus. Furthermore, as shown, the second laundry treatment apparatus 200 may be provided in the other in the form of a pedestal, that is, a pedestal, in which case the laundry treatment apparatus has a more compact form. do. On the other hand, although not shown, the first and second laundry treatment apparatus (100,200) may be designed to have a similar size to each other to have the same in design with each other.

The first and second laundry treatment apparatus (100,200) may be basically any one of a washing machine, a dryer, or a washing machine having a drying function. The first and second laundry treatment apparatuses 100 and 200 have housings 110 and 210 which form a common shape in common. In the case of the first laundry treatment apparatus 100, the doors 120 are installed in the housings 110 so as to put laundry therein, while the second laundry treatment apparatus 200 having a pedestal shape. In the case, the housing 210 is provided with a withdrawable drawer 220 to put the laundry therein. In addition, a control panel 130 is provided in the housing 110 to direct operation. More specifically, when the first or second laundry treatment apparatus (100,200) is made of a washing machine, a tub is installed in the housing (110,210) to store the wash water, and the drum is accommodated in the tub to accommodate and wash the laundry. It is rotatably installed. In addition, a drive mechanism for rotating the drum is provided in the housings 110 and 210. If the first or second laundry treatment apparatus (100,200) is made of a washing machine having a drying function, in addition to the above-described configuration, a duct and a heating device may be provided in the housing (110,210) to supply hot air into the drum. Can be. On the other hand, when the first or second laundry treatment apparatus (100,200) is made of a dryer, the drum is rotatably installed to accommodate and dry the laundry in the housing (110,210). In addition, a heating device and a duct structure are provided to supply hot air into the drum. Since the second laundry treatment apparatus 200 has a relatively small internal space compared to the first laundry treatment apparatus 100, the components of the washing machine, the dryer, or the washing machine having a drying function are gathered in a reduced form. It is provided in the space inside the drawer 220 of the second laundry treatment apparatus 200. Although the first and second laundry treatment apparatuses 100 and 200 may have a control device individually, a single unit controlling the first and second laundry treatment apparatuses 100 and 200 simultaneously to simplify the structure and reduce the production cost. It may have a control device. This single control device may be installed in any one of the first and second laundry treatment apparatus (100,200).

In addition, as shown, the first and second laundry treatment apparatus (100,200) may be arranged in parallel with each other. Therefore, the user can easily access the first and second laundry treatment apparatus (100,200), and thus can conveniently use the laundry treatment apparatus. On the other hand, likewise for the convenience of the user, the first and second laundry treatment apparatus (100,200) may be arranged vertically. That is, the other one may be placed on the upper portion of any one of the first and the second turbidity treatment apparatus (100,200). 1 illustrates a combination of the first laundry treatment apparatus 100 mounted on the second laundry treatment apparatus 200.

In such a laundry treatment apparatus, the first and second laundry treatment apparatuses 100 and 200 are often operated together. However, such a laundry treatment apparatus constitutes one system substantially, so that limited power is supplied thereto. Accordingly, if the first and second laundry treatment apparatuses 100 and 200 are driven together, the power used may exceed this supply power, and in this case, the laundry treatment apparatus may not operate properly. Can be broken. In particular, the first and second laundry treatment apparatuses 100 and 200 have a heater in common, and they consume the most power when compared with other components. When the first or second laundry treatment apparatus (100,200) is a washing machine, at least a heater for heating the wash water, and in the case of the dryer, the heater for heating the air to make hot air for drying. That is, the first and second laundry treatment apparatuses 100 and 200 have substantially the first and second heaters, respectively, and if the first and second heaters are operated at the same time, the power to be used is supplied. Can easily be exceeded. Thus, in the laundry treatment apparatus, when the first and second laundry treatment apparatuses 100 and 200 are operated together, these first and second laundry treatment apparatuses 100 and 200 control the respective first and second heaters. Thereby, it needs to be configured to adjust the power consumption appropriately. The laundry treatment apparatus and the control method for adjusting the power consumption is described below with reference to the accompanying drawings.

2 is a flowchart illustrating a control method of a laundry treatment apparatus according to the present invention.

When the laundry treatment apparatus is operated together, the laundry to be processed is first introduced into the first laundry treatment apparatus 100 and the second laundry treatment apparatus 200 which is installed adjacent to the first laundry treatment apparatus (S10). .

After the input step S10, the user instructs the first and second laundry treatment apparatuses to operate using the control panels 130 and 230 provided in each of them (S20). In this indicating step S20, the user May direct operation to the first and second laundry treatment apparatuses 100 and 200 at the same time. That is, the first and second laundry treatment apparatuses 100 and 200 start to operate at the same time. On the other hand, for various reasons, the user may first instruct the operation of any one of the first and second laundry treatment apparatuses 100,200, and after a predetermined time, instruct the operation of the other. That is, the starting point of operation of the first and second laundry treatment apparatuses 100 and 200 may be different from each other.

Subsequently, in consideration of the set operating conditions, the control device of the laundry treatment apparatus prioritizes the operation of the first heater installed in the first laundry treatment apparatus 100 and the second heater installed in the second laundry treatment apparatus 200. Determine the rank (S30). As mentioned above, among the various components of the laundry treatment apparatus, the first and second heaters are the biggest factor in the increase of the use power. Therefore, only one of the first and second heaters may be operated while the first and second laundry treatment apparatuses 100 and 200 are operated together in order to use power within a predetermined supply power range. need. In this case, it is also important to give priority to any of the first and second heaters in order for the laundry treatment apparatus to operate efficiently.

More specifically, in the determination step (S30), first, the control device compares the set operating conditions of the first laundry treatment apparatus with the operating conditions of the second laundry treatment apparatus. Thereafter, the controller selects a heater to be operated first of the first and second heaters based on the comparison result. In the comparing step, the control device is the amount of laundry to be processed in the first and second laundry treatment apparatus, the set operating time of the first and second laundry treatment apparatus, the set operating course of the first and second laundry treatment apparatus Can be compared with each other. In addition, the controller may compare the required power amounts of the first and second heaters with target heating temperatures of the first and second heaters. As such, the determination of which of the parameters compared with each other gives priority to the heater having a parameter may vary depending on the operating algorithm. Nevertheless, if the user sets detailed operating conditions such as an operating time or driving course to only one of the first and second laundry treatment apparatuses, the corresponding laundry treatment apparatus which is intended for a special operation, that is, operation It is preferable that the heater of the laundry treatment apparatus having the set time or driving course be determined to be operated first. In addition, when the operating time of any one of the first and second laundry treatment apparatus is less than the other operation time, it is determined that the heater of the laundry treatment apparatus having a lower operating time is to be operated first of the efficient laundry treatment apparatus. It is desirable for operation. In addition, the control panel and the control device may be provided with an option for the user to select the operating order of the first and second laundry treatment devices, the first and the second in accordance with the operation order of the processing devices selected from these options. 2 The operating sequence of the heater can be determined.

After the determination step (S30), the control device first operates the determined heater. Thereafter, as described above, the controller selectively operates only one of the first and second heaters such that at least the power used does not exceed the power supply (S40). In this selective operation step S40, in order to effectively and efficiently operate the laundry treatment apparatus, the selective operation of the first and second heaters is performed according to predetermined operation modes. In addition, as described above, in relation to the instruction step, the first and second laundry treatment apparatuses 100 and 200 may be operated at the same time or may be operated with a predetermined time difference, in each of these cases. The operation steps, precisely the operation modes, may be different from each other. 3 shows an operation mode when the first and second laundry treatment apparatuses 100 and 200 start to operate at the same time, and the operation mode will be described with reference to the following.

3 illustrates an operation sequence in which the heater operates when the first laundry treatment apparatus 100 and the second laundry treatment apparatus 200 operate at the same time. As such, when the first and second laundry treatment apparatuses 100 and 200 operate at the same time, the first and second heaters provided thereto are not in operation. Accordingly, the operation mode P of FIG. 3 is applied to the state in which the first and second heaters are not actually operated. Meanwhile, even if the first and second laundry treatment apparatuses 100 and 200 are not operated at the same time and the first and second laundry treatment apparatuses 100 and 200 start with a predetermined time difference, The laundry treatment device that follows can be started before the heater is activated. Even in this case, since the first and second heaters are still not in operation, the operation mode P according to FIG. 3 can be applied.

In addition to the operation mode P of FIG. 3 as well as the operation mode Q of FIG. 4 to be described later, the operation step S40 basically uses the first heater of the first laundry treatment apparatus 100. A first heating step of driving, and a second heating step of driving a second heater of the second laundry treatment apparatus 200 which is operated separately from the first heater. More specifically, the first and / or the second heating step is to wash the water in the tub when the first and / or second laundry treatment apparatus (100,200) consists of a washing machine, the first and / or second heater Means for heating by using, and when the first and / or second laundry treatment apparatus (100,200) consists of a dryer, heating the air supplied into the drum by using the first and / or second heater. Means. That is, the first and second heating steps in general mean a step of heating the corresponding objects to be heated by using the first and second heaters, that is, washing water or air for drying.

Referring to the operation mode P of FIG. 3 in more detail, M means to operate the first heater of the first laundry treatment apparatus 100, S is the second of the second laundry treatment apparatus 200. It means to operate the heater. The subscript if refers to the step in which the heater starts to operate and the heating object is heated until it reaches a preset temperature and then turns off. In addition, the subscript i means a step in which the operation of the heater starts, f is a step in which the operation of the heater is terminated. In addition, the case of no addition means that the operation of the heater is in progress.

In addition, in operation modes P1 to P4, when it is determined that the first heater is operated first in the determination step S30, the first heater determined in the determination step S30 is first operated in the operation step S40. The case is shown. In addition, the operation modes P5 to P8 indicate a case in which 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, the operation mode P1 starts to operate the first heater to heat the object to be heated in the first laundry treatment apparatus 100 to a first set temperature and then ends (M _if ), the second heater starts to operate. By the heating of the object to be heated in the second laundry treatment apparatus 200 to the second set temperature (S _if ) is shown.

In the operation mode P2, first the first heater starts to operate (M _i ), and after a predetermined time elapses, the first heater is temporarily stopped. Thereafter, the second heater starts to operate and ends after heating the heating object of the second laundry treatment apparatus 200 to the second set temperature (S _if ). Subsequently, after the first heater heats the heating object of the first laundry treatment apparatus 100 to the first set temperature, the operation is terminated (M _f ).

In the operation mode P3, first the first heater starts to operate (M _i ), and after a predetermined time elapses, the first heater is temporarily stopped and the second heater starts to operate (S _i ). Thereafter, when a predetermined time has elapsed, the operation of the second heater is temporarily stopped, and again, the first heater heats the heating object of the first laundry treatment apparatus 100 to the first set temperature, and then ends the operation (M _f). ). After the operation of the first heater is finished, the second heater is terminated after heating the heating object of the second laundry treatment apparatus 200 to the second set temperature. (S _f ).

In the operation mode P4, first the first heater starts to operate (M _i ), and after a predetermined time elapses, the first heater is temporarily stopped and the second heater starts to operate (S _i ). Thereafter, again, the operation of the second heater is temporarily stopped and the first heater is operated again (M). Thereafter, the operation of the first heater is temporarily terminated again, and the second heater heats up the heating object of the second laundry treatment apparatus 200 to a second set temperature, and then ends the operation (S _f ). Next, after the first heater heats the heating object of the first laundry treatment apparatus 100 to a first set temperature, the operation is terminated (M _f ).

On the other hand, the operation modes P5, P6, P7, P8 are similar to the operation modes P1, P2, P3, P4. However, since the second heater is determined to be operated first in the determination step S30, only the order of operating the first heater and the second heater, that is, only M and S are changed. For example, in the operation mode P5, after the second heater starts to operate first, the heating object of the second laundry treatment apparatus 200 is raised to the second set temperature, and then terminates (S _if ), the first heater is turned off. The process of starting the operation and raising the object to be heated of the first laundry treatment apparatus 100 to the first set temperature and then ending the process (M _if ) is shown.

As a result, in the operation mode P1 or the operation mode P5, after any one of the first heating step and the second heating step is completely performed, that is, after the heating object is heated to a predetermined temperature, the remaining steps are performed. That is, according to the operation mode P1 or P5, the operation step (S40) continuously continues any one determined in the determination step of the first heater and the second heater until the object to be heated first is heated to a predetermined temperature. It is made to operate. In addition, after the operation step of the determined heater, the operation step (S40) includes operating the other one of the first heater and the second heater until the object to be heated to a predetermined temperature.

In addition, 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 include heating objects of the first and second laundry treatment apparatuses 100 and 200 at corresponding set temperatures. It can be done alternately until it is reached. 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 first for a predetermined time, and then the corresponding objects are respectively heated to predetermined temperatures. Alternately operating the first and second heaters for a predetermined time. In the alternating operation of the first and second heaters in this operation step S40, the respective operating times of the first and second heaters can be changed as appropriate. That is, the respective operating times of the first and second heaters may be the same, but may be set differently in consideration of the set operating conditions.

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

The operation mode Q shown in FIG. 4 is connected to the first heater when one of the first laundry treatment apparatus 100 and the second laundry treatment apparatus 200 starts to operate the other one. The procedure of driving a 2nd heater is demonstrated. As described above, even if the first and second laundry treatment apparatuses 100 and 200 start with a predetermined time difference, the following laundry treatment apparatus starts to operate before the heater of the laundry treatment apparatus which has been started starts. Can be. In this case, since the first and second heaters are still not in operation, the operation mode P according to FIG. 3 is applied. Accordingly, the operation mode Q according to FIG. 4 may be applied when the first and second laundry treatment apparatuses 100 and 200 are operated at a time difference, and any one of them is already operating. In this case, the control device may stop the operation of the heater in operation or continue operation according to the determination of the determination step (S30) previously performed.

Referring to the operation mode Q of FIG. 4 in more detail, M means operating the first heater of the first laundry treatment apparatus 100, and S is the second of the second laundry treatment apparatus 200. It means to operate the heater. The subscript if refers to the step in which the heater starts to operate and the heating object is heated until it reaches a preset temperature and then turns off. In addition, the subscript i denotes a stage at which the operation of the heater is started, and f denotes a stage at which the operation of the heater is terminated. In addition, the case of no addition means that the operation of the heater is in progress. Finally, the subscript s means to temporarily stop the operation of the heater.

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

More specifically, in the operation modes Q1 to Q3, if it is determined that the second heater is operated first in the determination step S30, the second laundry treatment apparatus 200 is operated and its operation of the second heater is prevented. When required, the operation of the first heater of the first laundry treatment apparatus 100 that was in operation is stopped, and the operation modes when the operation of the second heater starts. That is, according to the operation modes Q1-Q3, the operation step S40 may include: stopping the heater that is operated when a heater that is not determined in the determination step S30 among the first and second heaters is in operation; The step of operating the determined heater of the first and second heaters is first performed. In addition, in the operation modes Q4 to Q7, if it is determined that the first heater is operated first in the determination step S30, the first laundry treatment apparatus may be newly operated even if the second laundry treatment apparatus 200 starts to operate newly. Operation modes when the operation of the first heater of 100 is continuously performed are shown. That is, according to the operation modes Q4-Q7, the operation step S40 is a step of continuously operating the determined heater when the heater determined in the determination step S30 among the first and second heaters is in operation. You do it first.

The driving modes Q1-Q7 will be described in more detail. First, in the driving mode Q1, the second laundry treatment apparatus is operated while the first heater is first operated (Mi), and the second heater is operated in the determination step S30. If it is determined to be activated first, the operation of the first heater is temporarily stopped (Ms). Thereafter, the second heater starts to operate and ends after heating the heating object of the second laundry treatment apparatus 200 to a second set temperature (S _if ). Thereafter, the first heater is operated again to heat the object to be heated of the first laundry treatment apparatus 100 to a first set temperature and then ends (M _f ).

In operation mode Q2, when the second laundry treatment apparatus is operated while the first heater is first operated (Mi) and it is determined that the second heater is operated first in the determination step S30, the operation of the first heater is temporarily performed. It goes through the step (Ms) to stop. After that, the second heater starts to operate (S _i ). If 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 terminated after heating the heating object of the second laundry treatment apparatus to a second set temperature (S _f ). Thereafter, the first heater is terminated after heating the heating object of the first laundry treatment apparatus 100 to a first set temperature (M _f ).

In operation mode Q3, when the second laundry treatment apparatus is operated while the first heater is first operated (Mi) and it is determined that the second heater is operated first in the determination step S30, the operation of the first heater is temporarily performed. It goes through the step (Ms) to stop. After that, 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 target of the first laundry treatment apparatus 100 to a first set temperature and then ends (M _f ). . Thereafter, the second heater is finished after raising the heating object of the second laundry treatment apparatus 200 to the second set temperature (S _f ).

In the operation mode Q4, when it is determined that the first heater is operated first in the determination step S30, the first heater may be operated even if the second laundry treatment apparatus starts to be operated while the first heater is in operation Mi. The operation of is maintained continuously. In particular, the first heater is terminated after heating the heating object of the first laundry treatment apparatus 100 to a first set temperature (M _f ). Thereafter, the second heater starts to operate, and the operation is ended after raising the heating object of the second laundry treatment apparatus 200 to the second set temperature (S _if ).

In the operation mode Q5, when it is determined that the first heater is operated first in the determination step S30, the first heater may be operated even if the second laundry treatment apparatus starts to be operated while the first heater is in operation Mi. The operation of is maintained continuously (M). After a predetermined time has elapsed, the operation of the first heater is temporarily stopped, and the second heater starts to operate to increase the heating object of the second laundry treatment apparatus 200 to a second set temperature. Is terminated (S _if ). Thereafter, the first heater is operated again and ends after raising the heating object of the first laundry treatment apparatus 100 to a first set temperature (M _f ).

In the operation mode Q6, when it is determined that the first heater is operated first in the determination step S30, the first heater may be operated even if the second laundry treatment apparatus starts to be operated while the first heater is in operation Mi. The operation of is maintained continuously (M). After a predetermined time elapses, the operation of the first heater is temporarily stopped, and the operation of the second heater is started (S _i ). In addition, when a predetermined time elapses after the operation of the second heater is started, the second heater is temporarily stopped and the first heater raises the heating object of the first laundry treatment apparatus 100 to a first set temperature. Operation is terminated (M _f ). Thereafter, the second heater is terminated after raising the heating object of the second laundry treatment apparatus 200 to the second set temperature (S _f ).

In the operation mode Q7, when it is determined that the first heater is operated first in the determination step S30, even when the second laundry treatment apparatus starts to operate while the first heater is in operation Mi, the first heater is operated. The operation of is maintained continuously (M). After a predetermined time elapses, 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). Subsequently, after a predetermined time passes, the operation of the first heater is temporarily stopped again, and the second heater is terminated after raising the heating object of the second laundry treatment apparatus 200 to a second set temperature ( S _f ). Thereafter, the first heater is terminated after raising the heating target of the first laundry treatment apparatus 100 to a first set temperature (M _f ).

On the other hand, the operation modes Q8-Q14 are similar to the operation modes Q1-Q7. However, the operation modes Q8-Q14 are operation modes when the first laundry treatment apparatus 100 is operated while the second laundry treatment apparatus 200 is operated and the second heater is operated. Only the order in which the two heaters are operated, ie only M and S, are reversed.

As a result, the operation step (S40) according to the operation modes Q1 to Q3 and the operation modes Q8 to Q10 is to first stop the operation of the heater of the laundry treatment device in operation, and then operate the heater provided in the laundry treatment device that is newly operated. It may include an intermediate heating step. Here, the intermediate heating step may be an S _if step in the operation mode Q1 and an S _i step in the operation modes Q2 and Q3. In addition, the operation mode Q8 may be a M _if step, and the operation modes Q9 and Q10 may be a M _i step. In addition, an additional heating step of operating the heater provided in the laundry treatment apparatus that was in operation after the intermediate heating step is completed may be performed. Here, the additional heating step may be M _f step in Q1, M step in the operation mode Q2, M _f step in the operation mode Q3. In addition, the operation mode Q8 may be a step S _f , the operation mode Q9 may be an S step, and the Q10 may be an S _f step. That is, as shown in the operation modes Q1 to Q3 and the operation modes Q8 to Q10, the intermediate heating step and addition until the temperatures of the heating objects of the first and second laundry treatment apparatuses reach preset temperatures. The heating steps may be performed alternately. Therefore, considering 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 determined by stopping the heater that is not determined in the determination step S30. After the step of operating the first and second heaters alternately until the respective objects to be heated to each of the predetermined temperature to be heated consists of the steps of operating for a predetermined time. In the alternating operation of the first and second heaters in this operation step S40, the respective operating times of the first and second heaters can be changed as appropriate. That is, the respective operating times of the first and second heaters may be the same, but may be set differently in consideration of the set operating conditions.

In addition, the operation step (S40) according to the operation mode Q4 ~ Q7 and the operation mode Q11 ~ Q14, the continuous heating step for continuously operating the heater provided in the laundry treatment apparatus in operation, and the laundry treatment apparatus is newly operated It may also include an intermediate heating step for driving the heated heater. Here, the continuous heating step may be M _f step in the operation mode Q4, and may be M step in the operation modes Q5 to Q7. In addition, the intermediate heating step may be a S _if step in the driving mode Q4 and the driving mode Q5, and may be a S _i step in the driving mode Q6 and the driving mode Q7. The continuous and intermediate heating steps in the operation modes Q11-Q14 are similar to the corresponding steps in the operation modes Q4-Q7 described above, and only M and S are interchanged.

In the operation modes Q4 and Q11 among the operation modes, the intermediate heating step is performed to increase the temperature of the drying object to the setting temperature after the temperature of the drying object is increased to the setting temperature through the continuous heating step.
