3 is a block diagram showing a process of transferring information on a network system of the present invention. FIG. 4 is a graph illustrating a form of an electric charge. FIG. 4A is a graph showing time of use (TOU) information and critical peak pattern (CPP) information, and FIG. 4B is a RTP ( This graph shows real time pattern information.

Referring to FIG. 3, in the network system of the present invention, a specific component C may receive information related to energy (hereinafter, “energy information”) by communication means. In addition, the specific component (C) may be additional information (environmental information, program update information, time information, operation or status information of each component (breakdown, etc.), in addition to the energy information by the communication means, consumer habit information using the energy consumption unit, etc. ) Can be received further.

The environmental information may include carbon dioxide emissions, carbon dioxide concentration in the air, temperature, humidity, rainfall, rainfall or the like, solar radiation, air volume, and the like.

In another aspect, the information may include internal information, such as information related to each component (operation or state information of each component (such as a failure), energy usage information of the energy consumer, consumer habit information using the energy consumer, and the like), and the like. Information may be divided into external information (energy-related information, environmental information, program update information, time information).

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 I may be one of information such as electricity, water, and gas.

For example, information related to electricity includes time-based pricing, energy curtailment, grid emergency, grid reliability, energy generation amount, and operational priority. (operation priority), energy consumption amount (Amount). In this embodiment, the fee associated with the energy source may be referred to as an energy fee.

In other words, energy-related information may be classified into charge information (energy charge) and non-charge information (energy reduction, emergency situation, network safety, generation amount, operation priority, energy consumption amount, etc.).

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 I 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. The energy information I may change with time.

Referring to FIG. 4A, according to the TOU information, data is gradually changed in 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. That is, in the case of the CPP pattern, the general fee is lower than that of the TOU pattern, but the charge at a specific time point is significantly higher than that in the TOU pattern.

Referring to FIG. 4B, according to the RTP information, data changes in real time with time.

Meanwhile, the energy information I may be transmitted and received with a true or false signal, such as a Boolean on a network system, or actual price information may be transmitted or received, or may be leveled and transmitted. Hereinafter, information related to electricity will be described by way of example.

When the specific component C receives a true or false signal such as a Boolean, one of the signals is recognized as an on-peak signal, and the other signal is off-peak. ) Can be recognized as a signal.

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

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

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. The specific component may determine the driving method in advance before starting the operation, or may change the driving method when the on-peak is recognized after starting the operation.

And, if a particular component recognizes an off peak, the output can be restored or increased as needed. That is, when a specific component that recognizes an on peak recognizes an off peak, the output may be restored to a previous state or increased more than the previous output.

At this time, even when the specific component recovers the output or increases the output after recognizing the off-peak, the total power consumption and / or the total electricity bill for the entire operating time of the specific component is reduced.

Alternatively, when the specific component recognizes an on-peak (for example, a recognition time), the output may be maintained when the specific component is operable. In this case, the operable condition means that the information value related to driving is equal to or less than a predetermined standard. The information value related to the driving may be information on an electric charge, power consumption amount 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 the specific component is the total power consumption or total power when the specific component operates at the 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 a refrigerator, the output may be overcooled by increasing the output, or in the case of a washing machine or a washing machine, the hot water may be stored in the hot water tank by driving the heater in advance than the scheduled time of operation of the heater. This is to reduce the electric charge by operating in the off-peak in advance to operate in the on-peak to come later.

Alternatively, when a specific component recognizes an off-peak (eg, a recognition time), power storage may be performed.

In the present invention, the specific component (for example, the energy consumption unit) may maintain, reduce or increase the output. Thus, a particular component can include a power changing component. Since the power can be defined by current and voltage, the power variable component can include a current regulator and / or a voltage regulator. For example, the power variable component may be operated according to a command generated from an energy management unit.

Meanwhile, the energy curtailment 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. That is, a turn off signal or a lower power signal may be transmitted and received.

When the specific component recognizes the energy saving information, as described above, the output can be zeroed (if the stop or stop state is recognized) or the output can be reduced (if the lower power signal is recognized). have.

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 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.

When the specific component receives the emergency information as schedule information, the specific component may increase the output before the arrival of the emergency time point, thereby performing the same operation as the above-described operation at the off peak of the specific component. . In addition, the specific component may be shut down at an emergency time.

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

That is, when an under frequency is detected (recognized) below the reference frequency of the AC power supplied to the component, the amount of supply electricity is determined to be low, and when the frequency higher than the reference frequency of the AC power is detected (recognized), the supply electricity is This can be judged by many.

When the specific component recognizes that the amount of electricity in the network safety information is low or the information that the electrical quality is not good, as mentioned above, the specific component to output 0 (stop or stop) in some cases, You can reduce the output, maintain the output, or increase the output.

The excessive amount of generated electricity information is information on a state in which excess electricity is generated since the amount of electricity consumed by the component consuming less energy than the amount of generated electricity may be transmitted / received as a true or false signal, for example, a Boolean.

When the specific component recognizes excessive power generation information (for example, when grid overfrequency is recognized or when over energy signal is recognized), 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 a refrigerator, the output may be supercooled by increasing the output, or in the case of a washing machine or a washing machine, the hot water may be stored by driving the heater in advance than the scheduled time of operation of the heater.

On the other hand, each kind of information related to the energy, specifically, the unprocessed first information (I1), the second information (second information (I2)) that is processed information from the first information, and the specific The information may be divided into third information I3 which is information for performing a function of a component. That is, the first information is raw data, the second information is refined data, and the third information is a command for performing a function of a specific component.

In addition, information related to energy is included in the signal and transmitted. In this case, one or more of the first to third information may be transmitted only a plurality of times without converting only the signal.

For example, as shown in the figure, any component that receives a signal including the first information I1 may only convert a signal and transmit a new signal including the first information I1 to another component.

Therefore, in the present embodiment, the signal conversion and the information conversion are described as different concepts. At this time, it will be easily understood that the signal is also converted when the first information is converted into the second information.

However, the third information may be delivered a plurality of times in the state where the contents are converted or in a state where only the signal is converted while maintaining the same contents.

In detail, when the first information is raw electricity price information, the second information may be processed electricity price information. The processed electric charge information is information or analysis information in which electric charges are divided into multiple levels. The third information is a command generated based on the first information or the second information.

The particular component may generate, transmit or receive one or more of the first to third information. The first to third information are not necessarily sequentially transmitted and received.

For example, only a plurality of third information may be transmitted or received sequentially or in parallel without the first and second information. Alternatively, the first and third information may be transmitted or received together, the second and third information may be transmitted or received together, or the first and second information may be transmitted or received together.

For example, when a specific component receives the first information, the specific component may transmit the second information, the second information and the third information, or may transmit only the third information.

When the specific component receives only the third information, the specific component may generate and transmit new third information.

Meanwhile, in the relationship between the two informations, one information is a message and the other information is a response to the message. Accordingly, each component constituting the present network system may transmit or receive a message, and when the message is received, may correspond to the received message. Thus, the transmission of messages and their corresponding responses is a relative concept for individual components.

The message may include data (first information or second information) and / or command (third information).

The command (third information) includes a data storage command, a data generating command, a data processing command (including generating additional data), a generating command of an additional command, a sending command of an additional generated command, and a received command. Commands and the like.

In the present specification, corresponding to a received message means storing data, processing data (including generating additional data), generating a new command, sending a newly generated command, and simply passing the received command to another component. Command can be generated together), operation, transmission of stored information, transmission of acknowledgment character or negative acknowledgment character.

For example, when the message is the first information, the component that has received the first information corresponds to this to generate the second information by processing the first information, generate the second information, and generate new third information, Only third information can be generated.

In detail, when the energy management unit 24 receives the first information (internal information and / or external information), the energy management unit 24 generates second information and / or third information to establish the home network. It may transmit to one or more components (for example, energy consumption unit) constituting. In addition, the energy consumption unit 26 may operate according to the third information received from the energy management unit 24.

The first component 31 may receive information from the utility network 10 or one or more components constituting the utility network 10, and transmit or process the received information to process the second to fourth components. Can be sent to (32, 34). For example, when the first component 31 is an energy measuring unit, the first component may receive electric charge information and transmit the electric charge information to an energy management unit, an energy consumption unit, or the like.

9 is a view showing a combination of the energy consumption unit and the display device according to the present invention, Figure 10 is a block diagram showing the configuration of the energy consumption unit and the display device according to the present invention.

9 and 10, the energy consumption unit 26 according to the present invention includes a first electrical appliance 100 or a second electrical appliance 300. For example, the first electrical appliance 100 may be a washing machine, and the second electrical appliance 300 may be a dryer.

On the first electrical appliance 100 or the second electrical appliance 300, the operation state of the electrical appliance or other additional information is displayed, or the operation of the first electrical appliance 100 or the second electrical appliance 300 The display device 200 that can control the is detachably mounted.

In detail, the display apparatus 200 may be the energy manager 24, the energy measurer 25, or the central manager 27, and may be a separate control device. The display apparatus 200 may control the operation of the energy consumption unit 24 or display an operation state based on information (energy information or additional information) transmitted from a network system.

The first electrical appliance 100 and the second electrical appliance 300 are formed with a first seating portion 110 and a second seating portion 310 to which the display apparatus 200 can be mounted. The first and second seating parts 110 and 310 may be recessed inward from an outer surface of the first and second electrical appliances 100 and 300.

The display apparatus 200 may be selectively mounted on the first electrical appliance 100 or the second electrical appliance 300.

When the display apparatus 200 is coupled to the first electrical appliance 100, the display apparatus 200 may communicate with the first electrical appliance 100. On the other hand, when the display apparatus 200 is coupled to the second electrical appliance 300, the display apparatus 200 may communicate with the second electrical appliance 300.

The display apparatus 200 may receive and display state information of the first electrical appliance 100 or the second electrical appliance 300.

Hereinafter, the structure of an electrical appliance and a display apparatus is demonstrated. The configuration of the first electrical appliance 100 and the second electrical appliance 300 is similar, and will be described based on the first electrical appliance 100, and the second electrical appliance 300 is the first electrical appliance 100 Use the description of).

The first electrical appliance 100 controls a first communication unit 130 that can communicate with the display apparatus 200, a first terminal unit 140 that can be connected to charge the display apparatus 200, and a configuration thereof. The first control unit 120 is included.

The display apparatus 200 includes a second communication unit 230 capable of communicating with the first communication unit 130, a display unit 250 for displaying state information of the first electrical appliance 100, and the display apparatus. An input unit 210 capable of inputting a predetermined command for operation of the 200 and a second control unit 220 for controlling these components are included.

The second communication unit 230 may receive state information and the like of the first electrical appliance 100 through communication with the first communication unit 130, and the received state information and the like may be received by the display unit 250. It can be displayed through.

The display apparatus 200 further includes a second terminal unit 240 that can be coupled to the first terminal unit 140, and a charging unit 270 that can be charged using power transmitted through the second terminal unit 240. .

The first communicator 130 and the second communicator 230 may communicate in a wireless manner. As described above, the wireless communication scheme may include zigbee, wi-fi, Bluetooth, or code division multiple access (CDMA), global system for mobile communications (GSM), or radio frequency (RF) scheme.

Therefore, even when the display apparatus 200 is in a state of being separated from the first electrical appliance 100, the first communication unit 130 and the second communication unit 230 can communicate with each other. It is possible.

However, the strength of the communication signal transmitted between the first communication unit 130 and the second communication unit 230 is inversely proportional to the square of the distance. Therefore, when the distance between the display apparatus 200 and the first electrical appliance 100 is greater than or equal to a predetermined value, communication may not be performed smoothly.

Another embodiment is proposed.

When the display apparatus 200 can communicate with both the first electrical appliance 100 or the second electrical appliance 300, the display apparatus 200 may communicate with an electrical appliance having a greater signal strength.

As described above, since the signal strength is inversely proportional to the distance, the display apparatus 200 may communicate with an electric product having a shorter distance.

For example, when the display apparatus 200 is located closer to the second electrical appliance than the first electrical appliance 100, the second communication unit 230 communicates with the communication unit of the second electrical appliance, The operating state of the second electrical appliance 300 may be displayed.

11 is a flowchart illustrating an embodiment of a control method for determining whether a display device according to the present invention can be used.

The display apparatus 200 according to the present invention may be available under predetermined conditions. That is, the display apparatus 200 may be used when it is in a state capable of communicating with the first electrical appliance 100 and in a state where transmission and reception of information through a communication signal is possible.

In other words, when the signal strength is secured to the extent that information can be included in the communication signal, the display apparatus 200 may be in a usable state.

On the other hand, the display apparatus 200 may be in an unusable state when it is in a state in which it cannot communicate with the first electrical appliance 100 or when information is not included in the communication signal due to a weak signal strength even though communication is possible. Can be.

Referring to FIG. 11, the first communication unit 130 of the first electrical appliance 100 according to the present invention transmits a predetermined signal to the second communication unit 230 of the display apparatus 200. At this time, the first electrical appliance 100 may be in a state where the power is turned on or may be in an off state.

In the state in which the first electrical appliance 100 is OFF, the display apparatus 200 may display that the first electrical appliance 100 is in an OFF state. The first electrical appliance may be used by using the input unit 210. The power of the product 100 can be turned on.

Although the first communicator 130 transmits a signal to the second communicator 230, the signal may be transmitted from the second communicator 230 to the first communicator 130.

Hereinafter, the first communication unit 130 will be described based on the first transmission of the signal to the second communication unit 230, but the second communication unit 230 may perform signal transmission first (S11).

The second communication unit 230 may receive a signal from the first communication unit 130 and retransmit the signal to the first communication unit 130. At this time, it is determined whether the first communication unit 130 receives a response signal from the second communication unit 230.

When the second communication unit 230 does not receive a signal from the first communication unit 130 from the beginning or when the first communication unit 130 does not receive a response signal of the second communication unit 230, The first communication unit 130 may recognize that the signal reception is impossible (S12).

When the signal is received from the second communication unit 230, the first communication unit 130 detects the signal strength received from the second communication unit 230 (S13, S14).

When the signal strength received from the second communication unit 230 is greater than or equal to a set value, the display apparatus 200 may be determined to be usable. Here, the set value is a signal strength value capable of transmitting and receiving information by communication, and may be set in advance (S15, S16).

In operation S15, when the signal strength received from the second communication unit 230 is less than a predetermined value, it is determined that the display apparatus 200 is unavailable.

At this time, the distance between the first communication unit 130 and the second communication unit 230 may be determined according to the ratio of the signal transmitted from the first communication unit 130 and the received signal strength. Of course, as the distance between the first communication unit 130 and the second communication unit 230 increases, the signal strength received from the second communication unit 230 will be weak (S17).

When the distance between the first communication unit 130 and the second communication unit 230 is determined, the first communication unit 130 may receive a signal strength greater than or equal to the set value from the second communication unit 230. The communication signal having a strength corresponding to may be retransmitted to the second communication unit 230.

Subsequently, if it is recognized that the signal received from the second communication unit 230 is greater than or equal to the set value, the display apparatus 200 may be recognized as usable.

Although not shown in the drawing, if it is recognized that the signal received from the second communication unit 230 is still less than the set value, the steps S17 and S18 may be repeated.

On the other hand, if a signal is not received from the second communication unit 230 in step S13, the first communication unit 130 may increase the signal strength and retransmit the signal to the second communication unit 230. Then, until the signal is received from the second communication unit 230, it is possible to perform steps S12 or less again (S19).

If it is determined that the display apparatus 200 is available, the user may not only check the state information of the first electrical appliance 100 through the display apparatus 200, but also the first electrical appliance 100. Can control the operation.

On the other hand, if it is determined that the display apparatus 200 is unavailable, the display apparatus 200 may display information indicating that the display apparatus 200 is unavailable.

As such, the distance between the display apparatus 200 and the first electrical appliance 100 may be determined based on the signal strength of the communication between the first communicator 130 and the second communicator 230. By adjusting the signal strength, it is possible to determine whether the display apparatus 200 can be used.

As a result, even when the display apparatus 200 is in a state of being separated from the first electrical appliance 100, it is possible to check the state information of the first electrical appliance 100 and to control the first electrical appliance 100. do.

12 is a flowchart illustrating another embodiment of a control method for determining whether a display device according to the present invention can be used.

Referring to FIG. 12, the first communication unit 130 according to the present invention may transmit a signal with minimum strength toward the second communication unit 230. In relation to the signal strength, the "minimum strength" may be defined as the signal strength of the state in which the display apparatus 200 is mounted on the first electrical appliance 100 (S21).

In operation S22, it may be determined whether the signal received from the second communication unit 230 is received. It is determined whether the signal strength received from the second communication unit 230 is greater than or equal to a set value. If it is recognized that the received signal strength is greater than or equal to a set value, the display apparatus 200 may be determined to be in a usable state (S23 and S24).

On the other hand, when it is recognized that the received signal strength is less than the set value (where "strength below the set value" includes that the signal strength is 0, that is, no signal is received), the first communication unit 130 may increase the signal strength and retransmit to the second communication unit 230. Then, the process of step S22 or less may be performed (S25).

As described above, it is possible to determine whether the display apparatus 200 can be used while gradually increasing the signal from the minimum signal strength.

Hereinafter, a further embodiment of the display device or the electrical appliance will be described. However, the differences will be mainly focused on comparison with the previous embodiment, and the same reference numerals refer to the previous embodiment.

13 is a block diagram showing a configuration capable of wireless charging of a display device according to the present invention.

Referring to FIG. 13, the first electrical appliance 100 according to the present invention includes a primary coil 180 provided for charging the display apparatus 200. In addition, the display apparatus 200 includes a secondary coil 280 that works with the primary coil 180.

In a state where the display apparatus 200 is mounted on the first seating unit 110, the primary coil 180 and the secondary coil 280 are located at a short distance.

When the line of magnetic force increases or decreases according to a change in the current flowing in the primary coil 180, a current is induced in the secondary coil 280. The charging unit 270 of the display apparatus 200 may be charged by a current induced in the secondary coil 280.

As such, the display apparatus 200 may be inductively charged from the first electrical appliance 100 in a state in which the display apparatus 200 is mounted on the first electrical appliance 100.

Another embodiment is proposed.

In place of the first and second terminal parts or the first and second coils described in the previous embodiments, a separate charging stand for charging the display apparatus 200 may be provided.

When the display apparatus 200 is discharged, the display apparatus 200 may be mounted on the charging station and charged. The charging method in the charging station may include an inductive charging method by combining the first and second terminal parts or the first and second coils described above.

14 is a block diagram showing a configuration of an energy consumption unit and a display device according to the present invention.

Referring to FIG. 14, the first electrical appliance 100 according to the present invention includes a first communication unit 130 for communicating with the display apparatus 200, a state value or a physical property value during operation of the electrical appliance 100. The first sensor 160 for detecting the detection and the first control unit 120 for controlling these components are included.

The display apparatus 200 includes a second communication unit 230 that can communicate with the first communication unit 130, and a second sensor 260 that senses a value comparable with the value detected by the first sensor 160. And a second control unit 220 for controlling these configurations.

By comparing the values detected by the first sensor 160 and the second sensor 260, it may be determined whether the display device 200 is attached or detached. That is, it may be recognized whether the display apparatus 200 is separated from the first electrical appliance 100.

The first sensor 160 and the second sensor 260 may be the same type of sensor. In this case, since the values detected by the first sensor 160 and the second sensor 260 may represent the same physical property value, the values detected by each sensor may be easily compared.

For example, the first electrical appliance 100 may be a washing machine or a dryer as an energy consumption unit, and the first sensor 160 and the second sensor 260 may be “vibration sensors”.

While the washing machine is in operation, a predetermined vibration may occur due to the rotation of the drum accommodating the quantity. In order to detect or control the vibration, the washing machine may be provided with a vibration sensor. Such a vibration sensor may correspond to the first sensor 160.

On the other hand, when the display apparatus 200 is mounted in the washing machine or within a predetermined distance from the washing machine, vibration may also occur in the display apparatus 200 due to the vibration of the washing machine. The second sensor 260 may detect whether the washing machine vibrates or the vibration value.

The first control unit 120 may obtain predetermined vibration value information detected by the first sensor 160 during the operation of the washing machine. In addition, the second controller 220 may acquire predetermined vibration value information detected by the second sensor 260 in this process.

For convenience, the vibration value detected by the first sensor 160 is referred to as "first vibration value" and the vibration value detected by the second sensor 260 is called "second vibration value".

The second vibration value may be transmitted to the first communication unit 130 through the second communication unit 230. In addition, the first controller 120 may compare the first vibration value and the second vibration value.

On the contrary, the first vibration value may be transmitted to the second communication unit 230 through the first communication unit 130. In this case, the second control unit 220 may transmit the second vibration value and the first vibration value. Can be compared.

Of course, when the display apparatus 200 is remotely located away from the first electrical appliance 100, the vibration value may not be detected from the second sensor 260.

However, even when the display apparatus 200 is not mounted to the first seating unit 110, when the display apparatus 200 is placed at a position on the first electrical appliance 100 or is located at a short distance outside the first electrical appliance 100. In this case, a predetermined vibration value may be detected.

In a state where the display apparatus 200 is mounted on the first seating unit 110, the difference between the first vibration value and the second vibration value may be smallest. If the display apparatus 200 is detached and mounted in the washing machine during operation of the washing machine, the difference between the first vibration value and the second vibration value may decrease.

In addition, when the first vibration value and the second vibration value are the same or similar, it may be recognized that the display apparatus 200 is mounted in the washing machine. The difference between the first and second vibration values for recognizing that the display apparatus 200 is mounted in the washing machine may be preset.

That is, when it is recognized that the difference between the first vibration value and the second vibration value is equal to or less than a specific reference value, it may be determined that the display apparatus 200 is mounted in the washing machine.

Another embodiment is proposed.

The first sensor 160 and the second sensor 260 may be “temperature sensors”. The first electrical appliance 100 may be a washing machine, a dryer, a refrigerator, a cooking appliance or a water purifier.

In detail, the first sensor 160 may be a temperature sensor that senses a temperature value to perform a specific function of the first electrical appliance 100. In addition, the second sensor 260 may be disposed within a predetermined distance of the first sensor 160.

That is, the display apparatus 200 may be disposed at a position that may be affected by the sensed temperature environment of the first electrical appliance 100.

When the difference between the value detected by the first sensor 160 and the value detected by the second sensor 260 decreases or when the difference decreases below a specific reference value (when the same or similar), the display The device 200 may be determined to be mounted on the first electrical appliance 100.

Another embodiment is proposed.

In the embodiment described above, the first sensor 160 is defined as a sensor provided to perform the unique function of the electrical appliance.

However, the first sensor 160 may be provided as a separate sensor for determining whether the display apparatus 200 is attached or detached. That is, the first electrical appliance 100 may include a unique sensor for driving the electrical appliance and the first sensor 160.

15 is a flowchart illustrating a control method of determining whether a display device is mounted during operation of the energy consumer according to the present invention.

A control method of determining whether the display apparatus 200 is attached or detached using the first sensor 160 and the second sensor 260 will be described.

The power source of the first electrical appliance 100 according to the present invention is turned on and driven in a specific manner (course) (S31).

During operation of the first electrical appliance 100, a predetermined physical property value is sensed by the first sensor 160 and the second sensor 260. As described above, the physical property value may be a vibration value or a temperature value (S32).

Communication between the first electrical appliance 100 and the display apparatus 200 is performed, and the detection results of the first sensor 160 and the second sensor 260 are compared (S33).

When the difference between the value of the first sensor 160 and the value of the second sensor 260 is equal to or less than a preset reference value, the display apparatus 200 may be determined to be combined (S36). On the other hand, if the difference between the value of the first sensor 160 and the value of the second sensor 260 exceeds a preset reference value, the display device 200 is determined to be separated from the first electrical appliance 100 (S37).

When it is determined that the display apparatus 200 is mounted on the first electrical appliance 100, the user may recognize that the user is located near the first electrical appliance 100. In this case, the first electrical appliance 100 may be controlled to generate less vibration or noise.

For example, when the first electrical appliance 100 is a washing machine or a dryer, the rotation speed of the drum in which the quantity is accommodated may be lowered. When the first electrical appliance 100 is a refrigerator, the driving cycle of the compressor may be reduced. Can be.

On the other hand, if it is determined that the display apparatus 200 is removed from the first electrical appliance 100, it may be recognized that the user is located far from the first electrical appliance 100. In this case, the first electrical appliance 100 may be controlled to increase intrinsic performance.

For example, washing or drying performance of a washing machine or a dryer may be improved, or cooling performance of a refrigerator may be improved.

In addition, when the display apparatus 200 is removed from the first electrical appliance 100, the auxiliary display unit provided in the first electrical appliance 100 is operated, or a lock function so that children cannot operate the electrical appliance. This may be done.

As such, depending on whether the display apparatus 200 is attached or detached, a method of controlling an electric product may vary, and user convenience may be increased.

16 is a flowchart illustrating a control method of determining whether to activate an additional function according to whether the display apparatus according to the present invention is available.

Referring to FIG. 16, a control method for selectively activating additional functions of an electric appliance according to whether a display device is available will be described. The availability of the display apparatus 200 may be determined by distance recognition between the display apparatus 200 and the first electrical appliance 100.

The determination of the distance recognition may be performed by determining whether the display apparatus 200 is attached or detached or the strength of a communication signal performed between the display apparatus 200 and the first electrical appliance 100.

In detail, whether the display apparatus 200 is attached or detached may be determined by the method described in the previous embodiment. When the display apparatus 200 is mounted on the first electrical appliance 100, the display apparatus 200 may be determined to be in a usable state.

Specifically, when the display apparatus 200 is mounted on the first electrical appliance 100, the distance between the display apparatus 200 and the first electrical appliance 100 is minimum, and the communication signal strength between the two is maximum. It may be defined as (S41).

On the other hand, if it is determined that the display apparatus 200 is separated, it is determined whether the display apparatus 200 can be used.

Whether the display apparatus 200 can be used may be determined by recognizing a communication signal strength or a separation distance between the display apparatus 200 and the first electrical appliance 100 described above.

That is, when a communication signal of sufficient strength is transferred between the display apparatus 200 and the first electrical appliance 100, it may be determined that the display apparatus 200 can be used. On the other hand, if the strength of the communication signal is weak, it may be determined that the use of the display apparatus 200 is impossible. (S43).

If it is determined that the display apparatus 200 can be used, the additional function of the first electrical appliance 100 may be deactivated. That is, the additional function may not be performed (S44, S45).

On the other hand, if it is determined that the use of the display apparatus 200 is impossible, the additional function of the first electrical appliance 100 may be activated. That is, the additional function may be performed.

The additional function may include a safety mode or an energy saving mode.

The safe mode includes a child lock mode.

When the display apparatus 200 is unavailable, the user may be determined to be out of a range in which the operation of the first electrical appliance 100 can be easily controlled. Accordingly, the lock mode is performed for the safe use of electrical appliances.

The lock mode is to prevent children from tampering with the electrical appliance, and may prevent the electric appliance from being turned on or off or opening the door of the electrical appliance.

The energy saving mode includes a power saving mode or a standby power mode.

If the display apparatus 200 is not available, a mode for minimizing power consumed from the first electrical appliance 100 may be performed.

For example, the power supply can be turned off, leaving only the power of a communication device (modem) required for communication in a network system. The power supply may be turned off while maintaining only a memory function for storing state information of the electrical appliance.

When the strength of the communication signal is greater than or equal to a preset reference value and the use of the display apparatus 200 is recognized as possible, the auxiliary display unit 400 may be turned off or additional information may be displayed.

Meanwhile, the illuminance of the display device may be gradually increased or decreased according to the strength of the communication signal. For example, when the intensity of the communication signal is large, the illuminance of the display device is high, whereas when the intensity of the communication signal is relatively small, the illuminance of the display device may be formed low.

In addition, among the input units provided in the display apparatus 200, the operation of the selectable input unit may be limited according to the strength of the communication signal.
