Meanwhile, in the network system of the present invention, a specific component may receive information related to energy (hereinafter referred to as "energy information") by the communication means. In addition, the specific component may further receive additional information (environmental information, status or operation information of another component, time information, etc.) in addition to energy information by the communication means. At this time, the information may be received from other components. In other words, the received information includes at least energy information.

The specific component may be one component constituting the utility network 10 or one component constituting the home network 20.

As described above, the energy information may be one of information such as electricity, water, and gas.

For example, the type of information related to electricity can include time-based pricing, energy curtailment, grid emergency, grid reliability, energy generation amount (or supply), Operation priority, energy consumption amount, and so on. In this embodiment, the fee associated with the energy source may be referred to as an energy fee.

Such information may be classified into schedule information previously generated based on previous information and real time information that changes in real time. The schedule information and the real time information may be distinguished by predicting information after the current time (future).

The energy information may be transmitted / received by a true or false signal such as a Boolean on a network system, an actual price may be transmitted or received, or a plurality of levels may be transmitted and received.

The energy information may be classified into time of use (TOU) information, critical peak pattern (CPP) information, or real time pattern (RTP) information according to a change pattern of data over time.

According to the TOU information, data is gradually changed over time. According to the CPP information, the data changes step by step or in real time with time, and emphasis is displayed at a specific time point. According to the RTP information, data changes in real time with time.

If the energy information is, for example, electricity rate information, the information related to the electricity rate is changed. The electric charge information may be transmitted / received by a true or false signal such as a Boolean on a network system, an actual price may be transmitted or received, or a plurality of levels may be transmitted and received.

When the specific component receives a true or false signal such as a Boolean, one signal may be recognized as an on-peak signal and the other signal may be regarded as an off-peak signal. have.

In contrast, a specific component may recognize information on at least one driving including the electric charge, and the specific component compares the recognized information value with the reference information value to turn on-peak and off-peak. (off-peak) can be recognized.

For example, when a specific component recognizes the leveled information or the actual price information, the specific component compares the recognized information value and the reference information value to the on-peak and off-peak ( off-peak).

In this case, the information value related to the driving may be at least one of an electric charge, a power amount, a change rate of the electric charge, a change rate of the power amount, an average value of the electric charge, and an average value of the electric power. The reference information value may be at least one of an average value, an average value of minimum and maximum values of power information during a predetermined section, and a reference rate of change of power information (eg, slope of power consumption per unit time) during the predetermined section.

The reference information value may be set in real time or may be set in advance. The reference information value may be set in a utility network or in a home network (input from a consumer direct input, an energy manager, a central manager, etc.).

When the specific component (for example, the energy consumption unit) recognizes an on-peak (for example, a recognition time point), the output may be zero (stopped or stopped) and the output may be reduced. And, if necessary, the output can be restored or increased. The specific component may determine the driving method in advance before starting the operation, or change the driving method when the on-peak is recognized after starting the operation.

Alternatively, when the specific component recognizes an on-peak (for example, a recognition time), the output is maintained when the specific component is operable. At this time, the operable condition means that the information value for driving is below a certain standard. The information value related to the driving may be information about an electric charge, power consumption, or operation time. The predetermined criterion may be a relative value or an absolute value.

The schedule standard may be set in real time or may be set in advance. The schedule criterion may be set in the utility network or in a home network (input from a consumer direct input, an energy manager, a central manager, etc.).

Alternatively, when the specific component recognizes an on-peak (eg, a recognition time), the output may be increased. However, even when the output is increased when the on-peak is recognized, the total output amount during the entire driving period of the specific component may be reduced or maintained than the total output amount when the specific component operates at the normal output. Or, even if the output is increased when the on-peak is recognized, the total power consumption or total electric charge for the entire operating period of a particular component is the total power consumption or total power when the specific component operates at normal output. It can be lower than the electricity bill.

When the specific component recognizes an off-peak (for example, a recognition time), the output may be increased. For example, when an operation reservation is set, a specific component may start driving before a set time, or a component having a larger output among a plurality of components may be driven first. In addition, in the case of the refrigerator to increase the output than the existing output supercooled, or in the case of a washing machine or a washing machine, the hot water can be stored by driving the heater in advance than the scheduled time of operation of the heater. Alternatively, when a specific component recognizes an off-peak (eg, a recognition time), power storage may be performed.

The energy reduction information is information related to a mode in which a component is stopped or a low electric charge is used. The energy saving information may be transmitted and received with a true or false signal, for example, as a Boolean on a network system.

The grid emergency information is information related to a power failure and the like, and may be transmitted / received as a true or false signal such as a Boolean. Information related to the power outage is related to the reliability of the component using energy.

When the specific component recognizes the emergency information, it may be immediately shut down.

The grid reliability information is information about a high or low amount of electricity supplied or information on the quality of electricity. The AC power is transmitted or received as a true or false signal, such as Boolean, or supplied to a component (for example, home appliance). The component may determine the frequency of the signal.

That is, when a frequency lower than the reference frequency of the AC power supplied to the component is detected, the amount of supply electricity may be determined to be small, and when a frequency higher than the reference frequency of the AC power may be determined, the amount of supply electricity may be determined.

When the specific component recognizes that the amount of electricity is low in the network safety information or the information that the electrical quality is not good, as described above, the specific component may be output 0 (stopped or stopped) in some cases. Can be reduced, the output maintained or the output increased.

The excessive amount of generated electricity information is information on a state in which surplus electricity is generated because the amount of electricity consumed by the component consuming energy is smaller than the amount of generated electricity. For example, the generated electricity amount may be transmitted and received as a true or false signal such as a Boolean.

When the specific component recognizes excess electricity quantity information, the output may be increased. For example, when an operation reservation is set, a specific component may start driving before a set time, or a component having a larger output among a plurality of components may be driven first. In addition, in the case of the refrigerator to increase the output than the existing output supercooled, or in the case of a washing machine or a washing machine, the hot water can be stored by driving the heater in advance than the scheduled time of operation of the heater.

Although not shown, the washing machine constituting the laundry treatment apparatus includes a drum accommodating the laundry cloth, a main heater for drying the laundry cloth, and the like.

In the present specification, the structure of the laundry treatment apparatus may use a conventional structure, and thus detailed description thereof will be omitted.

Meanwhile, the washing machine 40 includes a control panel 430 for inputting information related to the operation of the washing machine.

Referring to FIG. 4, the control panel 430 includes a power button 431 for turning on / off a power of the washing machine, and an operation button 432 for starting or stopping the operation of the washing machine or restarting the washing machine. A function selection part including a course or mode selection part (433: course selection part hereinafter) for selecting an operation course or mode, and a plurality of buttons for selecting a function desired by a user. 435, and a display unit 440 capable of displaying a selected item during operation of the function selection unit 435, a progress of a corresponding course (mode), and a remaining time.

For example, the course selector 433 may be rotated like a knob Knob.

The function selection unit 435 includes at least a smart button 438. The smart button 438 may select a smart function or release a smart function. In the present specification, the smart function means a function for efficiently managing (actually using) energy.

In the present embodiment, the function selection unit 435 and the course selection unit 433 may be collectively referred to as an input unit.

5 is a view showing another example of the control panel of the washing machine constituting the laundry treatment apparatus.

This embodiment is the same as that described in FIG. 4 in other parts, except that the smart course can be selected through the course selector 433.

Referring to FIG. 5, the course selectable by the course selector 433 in the present embodiment includes at least a smart course.

When the smart course is selected, a smart function for managing energy (for example, reducing energy consumption) is performed while operating as a preset course. In this case, since the smart course is a course for energy management, the course to be actually performed in the state in which the smart course is selected may be preset or changed by the user.

That is, when the smart course is selected, the washing machine performs an operation for energy management while operating as a standard course, for example. As another example, when the smart course is set to be performed in the smart course, when the smart course is selected, an operation for energy management is performed while operating as the strong course.

According to the present invention, since an input unit for selecting a smart function is provided, the user can easily select or deactivate the smart function regardless of the user's age, thereby improving user convenience.

6 is a flowchart illustrating a control method of the laundry treatment apparatus according to the first embodiment.

Referring to FIG. 6, a specific course is selected by the course selector 433 to operate the laundry treatment apparatus (S1). Then, the smart button 438 is selected (S2). In the present embodiment, the smart button 438 is selected by the user. Hereinafter, the smart button 438 is selected.

The smart button 438 may be selected before course selection or after course selection.

Then, the start button 432 is selected (S3). When the start button 432 is selected, it is determined whether the operation start condition of the laundry treatment apparatus is satisfied in the control unit (not shown) (S4). In detail, when the start button 432 is selected, the controller of the laundry treatment apparatus determines an estimated time required for the selected course. Next, the controller determines whether the sum of the sum of the estimated time required and the error time overlaps the on-peak period. That is, it is determined whether an on peak section arrives when the laundry treatment apparatus operates during the summation time.

In the present embodiment, the estimated time required may vary depending on the water supply pressure, laundry addition, etc. when the actual laundry treatment apparatus is operated. Therefore, the sum of the estimated time plus the error time corresponds to the on peak period. Determine whether or not.

As such, when it is determined that the error time is added to the expected peak time and corresponds to the on-peak period, the operation time of the actual laundry treatment device may be prevented from overlapping with the on-peak period, thereby increasing the fee, and improving the product reliability. There is this.

If the operation start condition of the laundry treatment apparatus is satisfied, the laundry treatment apparatus operates in the selected course (S5). Then, it is determined whether the course is completed during the operation of the laundry treatment apparatus (S8), and when the course is completed, the operation of the laundry treatment apparatus is stopped.

On the other hand, if it is determined in operation S4 that the operation start condition is not satisfied, a message indicating whether the condition is not satisfied is displayed on the display unit 440 (S6). In addition, the display unit 440 displays a message confirming whether to start the operation now.

Next, the controller determines whether a start command is input (S7). If the start command is input, the laundry treatment apparatus starts operation (S5). If the start command is not input, the laundry treatment apparatus waits for a start in a stopped state.

According to the present invention, since the laundry treatment apparatus performs a function for energy management, there is an advantage that the energy bill can be reduced during operation of the laundry treatment apparatus.

In addition, when the operation start conditions are not satisfied, the information is known to the user, so that the user can easily check whether the washing is possible, thereby improving the user's convenience and allowing the user to determine whether the operation starts again. There is an advantage that the laundry treatment device can operate centrally.

In the above embodiment, the smart button is selected, but in contrast, when the smart course is selected and the start button is selected, the process under step S4 is performed in the same manner.

7 is a view for explaining a control method of the laundry treatment apparatus according to the second embodiment.

Referring to FIG. 7, a specific course is selected by the course selector 433 to operate the laundry treatment apparatus (S11). Next, the smart button is selected (S12). In the present embodiment, the laundry treatment apparatus may be a washing machine.

Then, the start button 432 is selected (S13). When the start button 432 is selected, the laundry treatment device starts operation (S14). Then, while the laundry treatment apparatus is in operation, the controller determines whether the stop condition is satisfied (S15).

When the above stop condition is satisfied, on-peak recognition, energy-saving signal recognition, power generation quantity is less than the reference amount, frequency recognition lower than the reference frequency, energy consumption (energy consumption of household appliances, household appliances, energy consumption unit, etc.) This includes the recognition that the reference amount is higher than the reference value (a value set by a user or a value to which a progressive tax applies), and a case where an abnormal state (abnormal operating state) of an internal part is recognized.

If it is determined that the stop condition is satisfied, the laundry treatment apparatus stores the operation (S16). Then, the control unit determines whether the washing water is present in the laundry treatment apparatus (S17). At this time, in the present embodiment, the presence of the wash water means that the wash water is enough to require drainage.

If it is determined that the wash water is present in the laundry treatment apparatus, the drainage pump is operated to drain the wash water (S18). The reason why the drain pump operates in the present embodiment is to prevent laundry damage, odor, etc. due to the long time of the wash water.

Next, the control unit determines whether the operation start condition of the laundry treatment apparatus is satisfied (S19).

When the operating time condition is satisfied, when the off peak is recognized, when the current on peak section or the on peak section is included in the allowable section, and when the frequency higher than the current reference frequency is recognized, the current generation amount is greater than the reference amount. In the case of recognition, the present invention may include a case where one or more household utilities or one or more energy consumption units recognize that the current or cumulative energy consumption is lower than the reference amount.

When the operating time condition is satisfied, the laundry treatment apparatus returns to the original operating state (S20). Then, it is determined whether the course is completed during the operation of the laundry treatment apparatus (S21), and when the course is completed, the operation of the laundry treatment apparatus is stopped.

According to the present embodiment, when the information related to the energy saving is recognized during the operation of the laundry treatment apparatus, the operation may be stopped, and thus the energy usage fee may be reduced. In addition, if the abnormal ecology is recognized during operation of the laundry treatment apparatus, it may be stopped, and damage to the laundry treatment apparatus may be prevented.

In the above embodiment, when the start condition is satisfied, it is described as returning to the original state. Alternatively, it is also possible to continuously maintain the stopped state without determining whether the start condition is satisfied.

8 is a flowchart illustrating a control method of the laundry treatment apparatus according to the third embodiment.

Referring to FIG. 8, a specific course is selected by the course selector 433 to operate the laundry treatment apparatus (S21). Then, the smart button is selected (S22). In the present embodiment, the laundry treatment apparatus may be a dryer.

Then, the start button 432 is selected (S23). When the start button 432 is selected, the laundry treatment device starts operation (S24). Then, while the laundry treatment apparatus is in operation, the controller determines whether the stop condition is satisfied (S25).

When the above stop condition is satisfied, on-peak recognition, energy-saving signal recognition, power generation quantity is less than the reference amount, frequency recognition lower than the reference frequency, energy consumption (energy consumption of household appliances, household appliances, energy consumption unit, etc.) If it recognizes that it is higher than this reference amount (a value set by a user or the value which a progressive tax applies), it includes recognition of the abnormal state (abnormal operating state) of internal components, etc.

If it is determined that the stop condition is satisfied, the operation of the main heater for drying constituting the laundry treatment apparatus is stopped (S26). Next, the controller determines whether the operation start condition of the laundry treatment apparatus is satisfied (S27).

When the operating time condition is satisfied, in the case of the off peak section, when the current on peak section or the on peak section is included in the allowable section, and when a frequency higher than the current reference frequency is recognized, the current generation amount is greater than the reference amount. In the case of recognition, the present invention may include a case where one or more household utilities or one or more energy consumption units recognize that the current or cumulative energy consumption is lower than the reference amount.

When the operating time condition is satisfied, the main heater is restarted (S28). Then, it is determined whether the course is completed during the operation of the laundry treatment apparatus (S29), and when the course is completed, the operation of the laundry treatment apparatus is stopped.

In the above embodiment, when the start condition is satisfied, the dry heater is described as being re-operated. Alternatively, it is also possible to continuously maintain the stopped state without determining whether the start condition is satisfied.

In the above embodiments, for example, the display unit and the input unit are separately provided. However, the display unit may include a touch screen for inputting information by a touch method. In this case, the display unit serves as an input unit.
