Description

Network system and washing device

The present invention relates to a network system and a cleaning apparatus constituting the network system.

Suppliers simply supply energy sources such as electricity, water, and gas, and demanders simply use the supplied energy sources. Therefore, effective management in terms of energy production, distribution, or energy use is difficult to perform.

In other words, energy is a radial structure that is distributed from an energy supplier to a large number of consumers, that is, from the center to the periphery, and is characterized by a one-way supplier center rather than a consumer center.

The price information of electricity can not be known in real time, but it can be seen only through the power exchange, and because the price system is also a fixed price system, incentives such as incentives for consumers through price changes can not be used There was also a problem.

In order to solve these problems, there has been a lot of efforts recently to implement a horizontal, cooperative and distributed network that can efficiently manage energy and enable interaction between a consumer and a supplier.

An object of the present invention is to provide a network system and a cleaning apparatus capable of efficiently managing an energy source.

A network system according to one aspect includes: a utility network having an energy generating unit for generating energy; A home network including an energy consuming unit capable of consuming energy generated in the energy generating unit; And communication means for enabling transmission or reception of the energy information in the utility network or the home network, wherein the energy consuming unit includes a drain motor for draining the wash water, And a control unit for controlling the drain motor. When drainage of the wash water is required, an operation method of the drain motor is selected depending on whether information related to the energy reduction of the control unit is recognized.

A cleaning apparatus according to another aspect comprises: communication means capable of receiving information relating to energy; A control unit capable of communicating with the communication means; And a drain motor that is controlled by the control unit and drains the wash water. When drainage of the wash water is required during a specific stroke, the drain motor stops after a predetermined period of operation, and in the course of draining the wash water And when the water level reaches the reference water level, the next stroke is performed.

According to yet another aspect, a cleaning apparatus includes: communication means capable of receiving information relating to energy; A control unit capable of communicating with the communication means; And a drain motor that is controlled by the control unit and drains the wash water. When drainage of the wash water is required, an operation method of the drain motor is selected depending on whether information related to the energy reduction of the control unit is recognized .

According to the proposed invention, since the utility network can communicate with the home network, it is possible to efficiently produce, use, distribute, and store the energy source, thereby enabling effective management of the energy source.

Further, in the cleaning apparatus, since the drain pump is not continuously operated until drainage is completed, there is an advantage that the energy consumption or the energy use charge due to the operation of the drainage pump is reduced.

Referring to FIG. 3, in the network system of the present invention, the specific component C can receive information related to energy (hereinafter, "energy information") by communication means. Further, the specific component (C) can be configured to include additional information (environmental information, program update information, time information, operation or status information of each component (failure), and consumer habit information using the energy consumption unit Can be further received.

The environmental information may include carbon dioxide emission amount, carbon dioxide concentration in air, temperature, humidity, rainfall amount, rainfall amount, insolation amount, air amount, and the like.

On the other side, the information includes internal information such as information related to each component (operation or status information (failure) of each component, energy use information of the energy consumption part, consumer habit information using the energy consumption part, etc.) (Energy related information, environmental information, program update information, and time information).

At this time, the information can be received from other components. That is, the received information includes at least energy information.

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

The energy information I may be one of electricity, water, gas, and the like as described above.

For example, the types of information related to electricity include time-based pricing, energy curtailment, grid emergency, grid reliability, energy generation amount, (operation priority), and energy consumption amount (energy consumption amount). In this embodiment, the charge related to the energy source is an energy charge.

That is, energy related information can be classified into charge information (energy charge) and non-charge information (energy reduction, emergency situation, network safety, power generation, operation priority, energy consumption, etc.).

Such information can be divided into scheduled information generated in advance based on previous information and real time information that varies in real time. The schedule information and the real-time information can be classified according to the prediction of the information after the present time (future).

The energy information I may be divided 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 vary with time.

Referring to FIG. 4 (a), according to the TOU information, data is changed stepwise according to time. According to the CPP information, the data changes stepwise or real-time with time, and emphasis is displayed at a specific time point. That is, in the case of the CPP pattern, the general charge is cheaper than the charge of the TOU pattern, but the charge at the specific point in time is significantly more expensive than the charge in the TOU pattern.

Referring to FIG. 4 (b), according to the RTP information, data changes in real time according to time.

On the other hand, the energy information I may be transmitted or received as true or false signals such as Boolean on the network system, actual price information may be transmitted or received, or a plurality of levels may be transmitted and received. Hereinafter, an example of information related to electricity will be described.

When the specific component C receives a true or false signal such as a Boolean signal, it recognizes one of the signals as an on-peak signal and the other signal as an off-peak ) Signal.

Alternatively, the specific component may recognize at least one or more energy information including the electricity bill, and the specific component may compare the recognized information value with the reference information value to determine on-peak and off- peak) can be recognized.

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 determine on-peak and off-peak values, Lt; / RTI >

At this time, the recognized information value may be at least one of an electricity rate, a quantity of electricity, a rate of change of the electric rate, a rate of change of the quantity of electricity, an average value of the electricity rate and an average value of the electric quantity. The reference information value may be at least one of an average value, an average value of a minimum value and a maximum value of power information during a predetermined section, and a reference change rate of power information during a predetermined section (for example, a slope of power consumption amount per unit time).

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

If the specific component (eg, energy consuming unit) recognizes an on-peak (recognizes information related to the reduction of energy bills or energy consumption) (eg, when it recognizes) Stop or stop state) output can be reduced. The specific component may determine the driving method in advance before starting the operation, and may change the driving method when the on-peak is recognized after the operation starts.

And, if a particular component recognizes off-peak, it can recover or increase its output when needed. That is, when a specific component recognizing the on-peak recognizes an off-peak, the output may be restored to its previous state or may be increased (different from the previous state) than the previous output.

At this time, the total consumed power and / or the total electricity use charge during the entire driving time of the specific component is reduced, even when the output of the specific component is recovered or the output is increased after recognizing the off-peak.

Alternatively, when the specific component recognizes an on-peak (for example, a recognition time point), the output can be maintained if it is an operable condition. At this time, the operable condition means that the information value of the driving is below a certain standard. The information value regarding the drive may be an electricity rate, an amount of power consumption, a time relating to energy or information on operation time, and the like. The constant criterion may be a relative value or an absolute value.

In one example, the operable conditions are, for example, when the on-peak period is less than a predetermined time, when the operation remaining time is less than a predetermined time, when the energy charge when operating in the on- And the ratio of the on-peak period of the entire operation time when the energy consumption is less than a predetermined amount.

At this time, if the operating start point of the component is included in the on-peak period in the non-operating state of the component, the output of the component can be maintained if the operable condition is satisfied.

The predetermined criteria may be set in real time or may be set in advance. The predetermined criteria may be set in the utility network or in a home network (input by a consumer direct input, energy management unit, central management unit, etc.).

Alternatively, the output may be increased if the particular component recognizes an on-peak (for example, a point-in-time). However, even when the output is increased at the time when the on-peak is recognized, the total output amount during the entire driving period of the specific component can be reduced or maintained to be less than the total output amount when the specific component operates at the normal output.

Alternatively, the total power consumption or total electricity charge during the entire drive period of a particular component, even when the output increases at the time when it recognizes the on-peak, is the total power consumed or total It can be reduced than the electricity rate.

That is, after the output of the specific component increases, the output of the particular component may be reduced or the output may be zero.

If the specific component recognizes an off-peak (for example, a recognition time point), the output can be increased. For example, when the operation reservation is set, a component whose operation starts before a setting time or a component having a large output among a plurality of components can be driven first.

Further, in the case of a refrigerator, it is possible to store the hot water in the hot water tank by supercooling the output by increasing the output from the existing output, or by driving the heater before the expected operation time of the heater in the case of the washing machine or the washing machine. This is to operate the off-peak in advance to be operated at an on-coming peak to reduce the energy charge.

Or when a particular component recognizes an off-peak (for example, when it is recognized).

Or if the specific component recognizes an off-peak, the amount of generated electricity (or supplied amount) can be reduced.

In the present invention, the particular component (e.g., the energy consuming unit) may maintain, reduce or increase the output. Thus, a particular component may include a power changing component. Since the power can be defined by current and voltage, the power variable component may include a current regulator and / or a voltage regulator. The power variable component may, for example, be operated in response to an instruction issued from the energy manager.

On the other hand, the energy curtailment information is information related to a mode in which the component is stopped or the electricity fee is reduced. That is, the energy reduction information is information related to the reduction of the energy consumption amount or the energy charge. The energy reduction information may be transmitted or received as a true or false signal, such as a Boolean on a network system. That is, a stop signal (turn off signal) or a reduction signal (lower power signal) can be transmitted and received.

When the specific component recognizes the energy reduction information, it can reduce the output (when the lower power signal is recognized) or to zero the output as described above (if the stop or stop state is maintained) have.

Or when the specific component recognizes the energy reduction information (for example, when it recognizes it), the output can be maintained if it is an operable condition.

The emergency information (Grid emergency) is information related to a power failure or the like, and can be transmitted and received as a true or false signal, for example, as a Boolean. The information related to the power failure or the like is related to the reliability of components using energy.

If the particular component recognizes the emergency information, it may be immediately shut down.

When the specific component receives the emergency information as the schedule information, the specific component may increase the output before the arrival of the emergency time point and perform the same operation as the operation in the off-peak of the specific component described above . And, at the time of the emergency, the specific component can be shut down.

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

That is, when the underfrequency of the AC power supplied to the component is detected (recognized), it is determined that the supplied electricity quantity is small. If an overfrequency higher than the reference frequency of the AC power supply is detected (recognized) Can be judged to be many. That is, an underfrequency lower than the reference frequency corresponds to the information related to the reduction of energy consumption or energy bills.

When the specific component recognizes that the amount of electricity is low or the quality of the electricity is poor, the specific component may set the output 0 (stop or stop) depending on the case, as mentioned above, The output can be reduced, the output can be maintained, or the output can be increased.

The electricity generation excess information is information about the state where the electricity consumption of the component consuming energy is smaller than that of the electricity generation and the surplus electricity is generated and can be transmitted or received as a true or false signal such as Boolean.

The output can be increased if the specific component recognizes the generated electricity excess information (eg, when it recognizes grid overfrequency or recognizes an over energy signal). For example, when the operation reservation is set, a component whose operation starts before a setting time or a component having a large output among a plurality of components can be driven first. Further, in the case of a refrigerator, it is possible to store the hot water by supercooling the output by increasing the output from the existing output, or by driving the heater in advance of the scheduled operation time of the heater in the case of a washing machine or a washing machine.

When the specific component recognizes information that the energy consumption of the network itself or the home network is large, the output component may be set to output 0 (hold or stop) or to reduce the output , Or increase the output.

The specific component may increase the output if it recognizes that the energy consumption is less than the reference amount.

Specifically, each type of information related to the energy includes first information (I1) that is not processed, second information (I2) that is information processed in the first information, And third information (I3), which is information for performing a function of the 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.

And, energy related information is included in the signal and transmitted. At this time, at least one of the first to third information may be converted only the signal, but the content may be transmitted a plurality of times without being converted.

For example, as shown in the figure, a component receiving a signal including the first information I1 may simply convert a signal and transmit a new signal including the first information I1 to another component.

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

However, the third information may be transmitted a plurality of times in a state in which the contents are converted, or may be transmitted a plurality of times in a state in which signals are converted while maintaining the same contents.

In detail, when the first information is unprocessed electricity rate information, the second information may be processed electricity rate information. The processed electricity bill information is information or analytical information in which electric bill is divided into multiple levels. The third information is an instruction generated based on the first information or the second information.

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

For example, a plurality of third information can be transmitted and received in sequence or in parallel without 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.

In one example, when a particular component receives the first information, the particular component may transmit the second information, transmit the second information and the third information, or transmit only the third information.

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

On the other hand, in the relationship between two pieces of information, one piece of information is a message and the other piece of information is a response to a message. Accordingly, each component constituting the network system can transmit or receive a message, and can respond to a received message when receiving a message. Therefore, the transmission and correspondence of a message is a relative concept for individual components.

The message may comprise data (first information or second information) and / or instructions (third information).

The command (third information) includes at least one of a data storage command, a data generation command, a data processing command (including generating additional data), an additional command generation command, a further generated command transmission command, Command, and the like.

In this specification, responding to a received message means that it is necessary to store data, to process data (including generating additional data), to generate a new command, to send a newly created command, ), Operation, transmission of stored information, transmission of an acknowledge character or negative acknowledge character, etc.

For example, if the message is first information, the component that received the first information may generate a second information by processing the first information, generate second information, and generate new third information, Only the third information can be generated.

Specifically, when the energy management unit 24 receives the first information (internal information and / or external information), the energy management unit 24 generates the second information and / or the third information, And may be transmitted to one or more constituent components (e.g., an energy consuming unit). The energy consuming unit 26 may operate according to the third information received from the energy managing unit 24. [

The household appliances may include, for example, a refrigerator 55, a washing machine 60, an air conditioner 70, a dishwasher 80, a cooking device 90, and the like.

The washing machine 60 and the dishwasher 80 may be referred to as a washing device since they are devices for washing objects to be cleaned (clothes, dishes, etc.). At this time, the washing machine (60) and the dishwasher (80) each include a washing tub for receiving the object to be cleaned.

Hereinafter, the washing machine will be described as an example of the washing machine, and the description of the washing machine will be applied to the dishwasher as well.

9, the washing machine 60 of the present invention includes a control unit 610, a communication unit 620, an input unit 630 for inputting operating conditions, information related to the operating state, energy, A drain pump 650 for draining wash water used for washing, and a water level sensor 660 for sensing a water level of the wash water.

The communication means 62 may communicate with a component or utility network that constitutes a home network. Also, the communication unit 620 can communicate with the controller 610. The control unit 610 may receive at least one of the first information and the third information through the communication unit 620.

The controller 610 can recognize the energy related information and control the operation of the washing machine 60 according to the recognized information.

That is, the control unit 610 can recognize information related to the reduction of the energy consumption amount or the energy charge, and can recognize the information (recognition based on determination of the energy charge, energy reduction signal recognition, on- Etc.), at least the operation of the drain pump can be controlled.

Using the input unit 630, not only the input of the operating conditions of the washing machine 60, but also the normal mode and the smart mode for efficient energy consumption can be selected in relation to the energy. In this embodiment, the smart mode includes a mode for effectively using energy as well as a mode for reducing energy consumption or energy charge, as well as reserving energy when the energy charge is low. The user can select either the normal mode or the smart mode using the input unit 630 before the operation of the washing machine 60 is started. Also, while the washing machine is operating in the selected mode, it can be changed to the normal mode or the smart mode.

The drain pump 650 may include a drain motor. When the drain pump 650 is operated, the washing water is discharged to the outside of the washing machine through a drain passage (not shown).

Hereinafter, a control method of the cleaning apparatus will be described.

10 is a flowchart illustrating a control method of the cleaning apparatus according to the first embodiment.

Referring to FIG. 10, when the cleaning device is turned on and a start command is input, the cleaning device performs an operation for cleaning.

If the washing apparatus is a washing machine, the washing step, the rinsing step and the dewatering step are basically performed, and if the washing machine is a washing machine, the washing step, the rinsing step and the drying step can be performed.

At this time, in the washing step and the rinsing step of the washing apparatus, the object to be cleaned is washed using the washing water. The specific stroke referred to herein means an administration using wash water. And, in a specific stroke using wash water, drainage is required to carry out the next stroke.

After the cleaning device is started, a specific stroke using wash water is performed (S1). Then, it is determined whether the drainage is required in the control unit 610 during a specific stroke (S2).

If drainage is required, the controller causes the drain pump 650 to stop after a predetermined period of time (S3). In the present embodiment, the predetermined time is a necessary time until a siphon phenomenon occurs in the drainage passage. At this time, the predetermined time may vary depending on the arrangement of the drainage channels.

When the siphon phenomenon occurs in the drainage passage, the washing water can be drained even if the drainage pump 650 is not operated.

While the washing water is drained by the siphon phenomenon, it is determined whether the water level change rate exceeds the reference value (S4). At this time, the water level change rate can be determined by using the information sensed by the water level sensor 660.

If the water level change rate does not exceed the reference value (including the case where the water level change rate is zero), since the wash water is not substantially drained, the process returns to step S3.

On the other hand, when the water level change rate exceeds the reference value, it is determined whether the water level of the wash water has reached the reference water level (S5). At this time, the reference water level is a water level for judging that the drainage is completed.

If the water level of the wash water has not reached the reference water level, the process returns to step S3. On the other hand, if it is determined that the water level has reached the reference water level, the washing apparatus performs the next stroke (S6). For example, if the specific stroke is a cleaning stroke, the next stroke is a rinse stroke. If the specific stroke is a rinse stroke, the next stroke in the case of a washing machine is a dehydration stroke, and in the case of a dishwasher, the next stroke is a drying stroke.

In the above embodiment, if the rate of change of the water level does not exceed the reference value, the process returns to step S3. Otherwise, the washing pump 650 may be operated until the water level of the washing water reaches the reference water level. Then, when the water level reaches the reference water level, the cleaning pump 650 can be stopped.

According to the present embodiment as described above, since the drain pump is not continuously operated until drainage is completed, there is an advantage that the energy consumption amount or the energy use charge due to the operation of the drainage pump is reduced.

11 is a flowchart for explaining a control method of the cleaning apparatus according to the second embodiment.

Referring to FIG. 11, when the cleaning device is turned on and a start command is input, the cleaning device performs an operation for cleaning.

After the cleaning apparatus is started, a specific stroke using wash water is performed (S11). Then, it is determined whether the control unit 610 requires drainage during a specific stroke (S12).

When the drainage is required, it is judged whether information related to the energy reduction is recognized (S13). In the case of recognizing the information related to the energy reduction, it is possible to recognize on-peak recognition, energy reduction signal recognition, recognition when the power generation amount is below the reference amount, frequency recognition lower than the reference frequency, energy consumption (household appliances, Energy consumption) is higher than a reference amount (a value set by the user or a value to which the progressive tax is applied).

If the information related to the energy reduction is recognized, the control unit 610 causes the drain motor to stop at a first reference RPM for a predetermined period of time and then stop (S14). Then, the washing water can be drained by the siphon phenomenon.

Then, while the washing water is being drained by the siphon phenomenon, it is determined whether the water level change rate exceeds a reference value (S15).

If the water level change rate does not exceed the reference value (including the case where the water level change rate is zero), since the wash water is not substantially drained, the process returns to step S14.

On the other hand, when the water level change rate exceeds the reference value, it is determined whether the water level of the wash water has reached the reference water level (S16).

If the water level of the wash water has not reached the reference water level, the process returns to step S14. On the other hand, if it is determined that the water level has reached the reference water level, the cleaning apparatus performs the next stroke (S19).

On the other hand, if the energy reduction information is not recognized, the control unit controls the drain motor to operate at the second reference RPM (S17). Then, the wash water is drained by the drain motor. At this time, the first reference RPM is larger than the second reference RPM. The reason for this is to improve the drainage effect due to the siphon phenomenon.

Then, it is judged whether or not the water level of the washing water has reached the reference water level (S18). If the water level of the wash water has not reached the reference water level, the process returns to step S17. On the other hand, if it is determined that the water level has reached the reference water level, the cleaning apparatus performs the next stroke (S19). That is, when the energy reduction information is not recognized, the drain motor continuously operates at the second reference RPM until drainage is completed.

In the above embodiment, if the water level change rate does not exceed the reference value in the state where the energy reduction information is recognized, the process returns to step S14. Otherwise, the washing motor is operated until the water level of the wash water reaches the reference water level . Then, when the water level reaches the reference water level, the washing motor can be stopped.

According to the present embodiment as described above, in a state in which energy reduction is required, there is an advantage that the drainage pump is not continuously operated until the drainage is completed, so that the energy consumption or the energy use charge due to the operation of the drainage pump is reduced .
