And the user's key operation result, and the application of the requested heating step is limited. When included, it may include a display unit for displaying a warning message.

According to an embodiment of the present disclosure, a method of controlling an output of an electric range includes storing an initial voltage which is a voltage before driving an electric range, receiving a key operation related to driving the electric range from a user, and corresponding to the key operation.

In addition, the input operation unit 110 may select a priority driving crater according to a user's operation and generate a control signal for instructing priority driving of the selected priority driving crater. In other words, the input operation unit 110 may transmit a signal for requesting preferential driving of one or more heating elements among the plurality of heating elements to the controller 170.

According to various embodiments of the present disclosure, the input operation unit 110 may receive a user input for interlocking an electric range with an external power consumption measuring device.

 The input operation unit 110 may be implemented as input means such as a button, a dial, a touch pad, and the like.

The display unit 120 may display an operation state of the electric range. Here, the operation state may include whether each heating element is operated, a temperature (output, thermal power) of the operating heating element, an operating time of an operating heating element, an operation remaining time of an operating heating element, and a residual heat display.

The display unit 120 may be implemented by display means such as seven segments and a liquid crystal display (LCD).

The storage unit 130 may store various measured electric numerical values. In addition, the storage unit 130 may store information on output values to be applied for each heating stage, various default values, error code information, or warning message text.

The storage unit 130 according to an embodiment of the present invention may store information on the initial voltage value before the operation of the electric range measured in the electric range. According to an exemplary embodiment of the present disclosure, the initial voltage value is a value for measuring power consumed by a wire supplying a current to the electric range, not inside the electric range.

The storage unit 130 according to an embodiment of the present invention may store information on the output value to be applied in each step of heating and information on the amount of power consumption predicted for each step of heating. According to various embodiments of the present disclosure, the storage unit 130 may store data about an identification value of a power consumption measuring device for communicating with an external power consumption measuring device and an integrated power consumption value received in real time from the power consumption measuring device. In addition, the storage unit 130 may store a reference value of a voltage change for determining that another external device in the same wire is operating after checking the power consumption of the wire (an external wire that supplies current to the electric range).

 The driving controller 140 may include a plurality of switching elements. The switching elements may determine power supply or release. In addition, the driving controller 140 may include a plurality of power controllers for controlling the power supplied to the heat generator 150 according to a user's temperature setting (output setting). The power controllers may be implemented as an inverter. The plurality of power controllers may be positioned between the corresponding switching element and the heating element, and control the supply power according to a predetermined output among the maximum available power to be supplied to the heating element.

The heat generating unit 150 is composed of a plurality of heating elements to generate heat by using the power supplied through the drive control unit 140. The heating element is an induction heater (a heater using induction current generated by a magnetic field as a heat source, and when a metal is placed on the heater, current is generated in the metal by electromagnetic induction and the metal is heated by Joule heat), sheath heater The heater may be implemented as a heater, a ceramic heater, a plate heater, or the like.

Preferably, the power consumption measuring device may be a distribution box management device that supports a power strip or an IoT function to perform an IoT function. For example, when a power strip measuring an IoT function is implemented as a power consumption measuring device, the power tap may measure a degree of power consumed by connected devices. In addition, the information on the measured power consumption may be transmitted to the linked electric range side. At this time, the information on the power consumption measured in the multi-tap may be delivered to the electric range in real time or when requested by the electric range side.

The controller 170 may control the output unit to output an output value corresponding to the requested step when the temperature control of the electric range is requested through the input operation unit 110.

Although not shown in the drawings, the electric range includes a speaker for outputting a warning message and information on a setting change value by voice, a microphone for receiving a voice command of a user for output value manipulation, and a fireball according to various embodiments of the present disclosure. The apparatus may further include a weight sensor, a timer, and the like for determining whether a heating target exists.

Referring to FIG. 2, the controller 170 according to an embodiment of the present invention includes a wire voltage determiner 171, an appropriate power determiner 172, a notification generator 173, and an output value controller 174. Can be.

The wire voltage determination unit 171 is a component for measuring power consumed by a wire supplying a current to an electric range. The wire voltage determination unit 171 may measure an initial voltage which is a voltage before the electric range is operated to measure a power value consumed by the wire. At this time, the wire voltage determination unit 171 may measure electrical data (eg, voltage, current) at the position of the wire to which power is supplied to the electric range. In addition, the wire voltage determination unit 171 may measure the voltage and current in the state that the electric range is operating. Typically, the voltage when the electric range is running will be different from the voltage before starting, which can be understood as the voltage drop occurring while passing through the wire. The reason why the voltage decreases due to the wire is due to the resistance of the wire, and the resistance of the wire can be determined by physical factors such as the length and the cross-sectional area of the wire. Accordingly, the wire voltage determination unit 171 determines that the difference between the in-operation voltage and the in-operation voltage is a voltage generated by the resistance of the wire and measures the pre-operation voltage and the in-operation voltage in order to obtain this value. The difference can be calculated. In addition, the wire voltage determination unit, when measuring the voltage of the operating range of the electric range, and also measures the current, at this time can calculate the power consumption generated in the wire by the product of the measured current and the voltage drop made in the wire. .

In general, the larger the power consumption generated in the wires (the greater the range of voltage drops made in the wires), the poorer the wiring environment can be. For example, suppose a wire with a length of 1m has a resistance of 0.1 ohms and a voltage drop of 1V has occurred.If the same wire is formed with a length of 10m, it has a resistance of 10 ohms and 10V. Voltage drop can occur. In addition, when excessive voltage drop occurs in the wire, a problem such as heat generation of the wiring may be caused. In order to prevent such a problem, the wire voltage determination unit 171 may determine whether the power consumption generated from the wire is greater than or equal to a preset value. The storage unit 130 may store a reference value for consumption of power generated from the wire. When the wire voltage determination unit 171 determines whether the power consumption generated from the wire exceeds the reference value previously stored in the storage unit 130, the output value controller 174 controls the output of the electric range according to the result (eg, the requested value). Temperature control function).

The appropriate power determination unit 172 may determine whether the voltage fluctuates while the output is maintained while the electric range is in operation. In addition, the appropriate power determination unit 172 may determine whether the magnitude of the voltage variation is greater than or equal to a preset value. When the changed value of the voltage is greater than or equal to a predetermined value, the appropriate power determination unit 172 may determine that another external device in the same wire is additionally operated. When the proper power determination unit 172 determines that another device in the same wire is in operation, the notification generator 173 may control to output a warning message. In addition, the output value control unit 174 temporarily controls the output of the electric range (e.g., limiting the temperature upward adjustment of the electric range, temporarily lowering the output of the electric range) only when the proper power judging unit 172 determines that another device in the same wire is in operation. Adjustment).

According to various embodiments of the present disclosure, the appropriate power determiner 172 may perform a function in connection with an external power consumption measuring device. The electric range may receive data regarding power consumption measured by the power consumption measuring apparatus in cooperation with an external power consumption measuring apparatus (eg, a smart power tap capable of measuring power consumption) according to various embodiments. Accordingly, the appropriate power determination unit 172 may determine whether to use other devices other than the electric range and the power consumption generated by other devices based on data on power consumption received from an external power consumption measuring device. In addition, when the appropriate power determination unit 172 is requested by the user to adjust the output value of the electric range (heat generation step adjustment), the power consumption received from the external power consumption measuring device (integrated power consumption including the power consumption of the running electric range) And the sum of the predicted power consumption increase corresponding to the heating step requested by the user may be determined. The appropriate power determination unit 172 may transmit a corresponding matter to the output value control unit 174 when the sum value is greater than or equal to a preset reference value. Accordingly, the output value controller 174 may limit the application of the heating step requested by the user. Alternatively, according to various embodiments of the present disclosure, the output value controller 174 may control the power supply of another device connected to an external power consumption measurement device (for example, a smart power tap) that is linked to the external value. For example, the output value control unit 174 may control to switch off one switch for supplying power to the device with the highest power consumption among devices other than the electric range.

In addition, the controller 170 may control the power consumption of the electric range and power used by other devices other than the electric range and operate the power efficiently by interworking with an external power consumption measuring device in various ways. Accordingly, the controller 170 may prevent a breaker operation due to overcurrent and a fire hazard due to heat generation of the wire.

3 is a flowchart illustrating a procedure of output value control according to a current consumption and an external device operation in a wire according to an embodiment of the present invention.

The controller 170 may perform operation 305 for storing the initial voltage value. The initial voltage value refers to the value of the voltage measured before the electric range is operated.

Thereafter, the controller 170 may perform operation 310 for starting the operation of the electric range (eg, induction) according to a user's request. In addition, as the heating step is designated by the user, the controller 170 may perform operation 315 for setting an output value corresponding to the heating step.

Thereafter, when the electric range is operated, the controller 170 may perform operation 320 to measure voltage and current in the electric range being operated. The controller 170 may perform operation 325 for calculating a difference between the voltage of the electric range being operated and the voltage before operation (initial voltage value). The controller 170 may determine a voltage drop made at the wire based on a difference between an initial voltage and an operating voltage.

The controller 170 may determine the power consumption of the wire based on the difference between the initial voltage and the operating voltage calculated in operation 325 and the current measured in operation 320. In addition, the controller 170 may perform operation 330 to determine whether the power consumption of the wire is greater than or equal to a set value. As a result of the determination, when it is determined that the power consumption of the wire is larger than the set value, the controller 170 may perform operation 335 to adjust the output value (for example, reduce the output value by a predetermined size or change the default output value). According to various embodiments of the present disclosure, when the power consumption of the wire is larger than the set value, the operation may be stopped to display an error message.

When the power consumption of the wire is not greater than a preset value, the controller 170 may perform operation 340 of maintaining the output at the output value set by the user. In a situation where the output is maintained, the controller 170 may perform operation 345 for detecting occurrence of a change in voltage. If the voltage variation does not occur, the controller 170 may perform operation 340 for continuously controlling the set output value. On the other hand, when a voltage change occurs, the controller 170 may perform operation 350 to determine that another device in the same wire is in operation. The storage unit 130 may store a reference value for determining whether the voltage fluctuates, and if it is determined that the range of the changed voltage is greater than or equal to the reference value, the storage unit 130 may determine that another device in the same wire is in operation.

Thereafter, the controller 170 may perform operation 355 for outputting a warning message (for example, a message such as' Please stop using another device on the same wire) may be output). Furthermore, the controller 170 may further perform an operation of adjusting an output in addition to the warning message according to various embodiments. For example, when it is determined that another device in the same wire is in operation, the controller 170 may cut off the overcurrent by adjusting the heat generation step of the electric range by reducing the output power consumed in the electric range.

4 is a flowchart illustrating an operation of controlling an output of an electric range through interworking with a power consumption measuring apparatus according to various embodiments of the present disclosure.

According to the operation of FIG. 4, the controller 170 may perform operation 405 in communication with an external power consumption measuring device (eg, a smart power tap measuring power consumption). Thereafter, the controller 170 may perform operation 410 for receiving a real-time integrated power consumption value from the power consumption measuring apparatus. The integrated power consumption value may mean, for example, a sum of power consumed by the three connected devices, assuming that three devices are connected to one power strip.

Thereafter, the controller 170 may perform operation 415 confirming that the heating step adjustment is requested from the user. Thereafter, the controller may perform operation 420 to determine whether the sum of the predicted power consumption increase corresponding to the user's heat generation step adjustment and the integrated power consumption received from the power consumption measuring device is equal to or greater than a preset reference value. In this case, data on the predicted power consumption of each heating stage supported by the electric range may be stored in the storage 130. Based on this, the controller 170 may determine an increase amount of the predicted power consumption corresponding to the heat generation step requested by the user.

If it is determined in operation 420 that the sum of the integrated power consumption and the predicted power consumption increase is not greater than the reference value, the controller 170 may perform operation 430 to apply the requested heat generation step. In contrast, when it is determined in operation 420 that the sum of the estimated power consumption increase and the integrated power consumption is greater than or equal to a predetermined reference value, the controller 170 may limit the application of the heating step requested by the user and output a notification message. For example, assuming that the existing heating stage of the electric range was three stages, but the user requested to adjust the heating stage to four stages, the control unit 170 measures power consumption (eg, 3000 W) and three stages of the equipment currently being used together through the power strip. In step 4, it is possible to determine whether the sum of the power consumption (eg, 100 W) expected to increase when exceeding the maximum allowable value (a preset reference value, eg, 4000 W) is determined.

The controller 170 may perform operation 435 to determine whether the user inputs to the additional heat generation step after operations 430 and 425. When the controller 170 determines that the additional operation is input in operation 435, the controller 170 may perform operation 420 again.

Although not illustrated in FIG. 4, according to various embodiments of the present disclosure, the controller 170 may perform interaction with a home distribution box that performs an IoT function instead of a multi-tap. Accordingly, the controller 170 may control the output of the electric range based on the total power consumed in the home, not only considering the operation state of the connected device and the power consumption of the connected device. Accordingly, the present invention can prevent damage due to power supply cut-off, overheating caused by overcurrent, or device failure, which are frequently generated in the home.

According to various embodiments of the present disclosure, the controller 170 may be configured to block standby power consumed by a device other than an electric range through interworking with an external power consumption measuring device such as a power strip that performs an IoT function. For example, when there is a device other than an electric range in which a cord is connected to the smart power strip while the electric range and the smart power strip are linked, the controller 170 supplies power to the devices other than the electric range only when the electric range is in operation. The power strip can be controlled to temporarily turn off the supply switch.

5 and 6 are views illustrating adjustment of a heating stage of an electric range and display contents thereof according to an embodiment of the present invention.

Referring to FIG. 5, a key for adjusting the heating stage of the input operation unit 110 according to an embodiment of the present disclosure may be displayed as 502. The key for the heating step operation may be composed of a key for upward adjustment and a key for downward adjustment.

When the heating step is operated by the user, information on the currently set heating step may be displayed as shown in 501. The power consumption and the maximum allowable power consumption value according to the current heating stage may be visualized and displayed as a bar as shown in 504. 504 may be accompanied by text (eg, safety, normal, caution, etc.) to measure the risk of the value depending on the amount of power consumed. Based on the diagram shown in FIG. 5, the electric range may be determined to correspond to a safety stage as the current heat generation stage is three stages, and a power consumption value corresponding thereto is 1100 (W). In addition, according to various embodiments of the present disclosure, the electric range may include a display window 503 displaying a warning message. In this case, the display window 503 may display a warning message as an error code (for example, E0, E1, E2, etc.) or may display a notification in the form of a word or sentence such as 'restrict the operation of the external device'. According to various embodiments of the present disclosure, when the contents of the display window 503 displaying the warning message are changed and displayed, a warning sound may be output together.

610 and 620 of FIG. 6 illustrate the situation before (610) and after (620) the heating step up operation is performed in the specific invention step (step 7), respectively. First, as illustrated at 610, the electric range corresponds to a 'caution' state when the heat generation stage is set to 7. In this case, the state of power consumption illustrated in 504 may represent a result of referring to power consumption data received by an external power consumption measuring device as well as an electric range. For example, when only an electric lane is operated, even a seven-stage power consumption may not reach the 'caution' stage. However, if the power consumption of other devices used on the same wire is large, the sum of the power consumption of the electric range and the power consumption of the external device may correspond to the 'attention' stage, and the bar shape indicated at 504 is shown in 610. Most areas of can light up. The warning message display window 503 may not display a separate warning message until an additional heating step upward operation is performed. (E.g., E0: it can mean there is no warning)

However, when the additional heating step up operation is performed through the 601 key in a situation in which the notification bar for power consumption is displayed as 'caution', such as 610, the control unit 170 increases the power consumption according to the heating step up operation + the current sum. It is possible to determine whether the level of power consumption = (predicted total power consumption) is enough to cause the wire to generate heat or whether the breaker is low. The determination may be performed according to whether the estimated total power consumption exceeds a preset reference value. If it is determined that the estimated total power consumption exceeds the reference value, the controller 170 may control not to fulfill the user's request (heat generation step up operation). At the same time, a warning message (e.g., error code 'E1' or 'The external device can not increase the temperature due to high power consumption') can be displayed on the display window 503 indicating that the user's request has not been fulfilled.

In addition, according to various embodiments of the present disclosure, the controller measures power consumption of the electric range in operation, and converts a difference between the integrated power consumption received from the power consumption measuring device and the power consumption of the electric range into power consumption generated by an external device. And a warning message requesting to limit the connection of external devices if the power consumption generated by the external device is above the preset threshold (e.g., 'The external device consumes a high percentage of power. Turn off the external device. Please ”.

According to various embodiments of the present disclosure, the controller 170 may control a power consumption measuring device (for example, a smart power tap) to automatically limit the power supply consumed by standby power when the electric range is in operation.

In addition, according to various embodiments of the present disclosure, the electric range may determine a device connected to each outlet. Since the functions related to power consumption, standby power measurement, and power supply interruption of connected devices using smart outlets are well known, detailed descriptions will be omitted. Accordingly, the controller 170 controls to stop the power supply in order of low priority electric appliances according to the priority set by the user when there is a history of limited output more than a predetermined number of times (for example, output limited more than three times per hour). can do. Thereafter, when the electric range is received an OFF request, the electric range may control to resume power supply of the corresponding device when there is a history of stopping the power supply of another device during operation. In addition, when the electric range is predicted to consume a high level of power according to various embodiments (e.g., when a high level of heat generation is predicted for a long time by selecting the auto cooking function or setting a timer), The power supply to the outlet to which external devices (eg air conditioners, electric blankets, air purifiers, etc.) are connected can be interrupted / resume for a certain period of time. For example, when the timer of the electric range is set to 1 hour and it is determined that the level of power currently being used relative to the maximum allowable power is high, the controller 170 (eg, an external device power supply controller (not shown)) determines the first external device. Power supply to (e.g., air conditioners) can be stopped and resumed every 10 minutes.

In addition, according to various embodiments of the present disclosure, the controller 170 may include a crater replacement determination unit (not shown). The crater replacement determination unit may be provided when the electric range is implemented including a plurality of craters. And the crater replacement determination unit may determine the situation for the ON / OFF of the power for each crater and the heating step (output) for each crater. A function supported by the crater replacement determination unit will be described in detail with reference to Table 1 below.

Situation 1 Situation 2 Situation 3 The first crater O X X The second crater O O X The third crater X O X First external device O O O Second external device △ O O Third external device X △ O

(△: repeating interruption and resumption, O: ON state, X: OFF state) For example, in the situation 1 of Table 1, the crater replacement judging unit checks the ON state of the first and second craters and the OFF state of the third crater. Can be. Based on the information on the state of each crater determined by the crater replacement determiner, the controller 170 (eg, the external device power controller) may control the power of the interlocked external device according to the setting of each device. Device-specific settings may be set, for example, as shown in Table 2 below.

Always ON Suspend / Resume OFF First external device O X X Second external device X O X Third external device X X O

 The device-specific setting may be supported by a first option which is always set to an ON state, a second option which is set to be suspend / resume, and a third option which is kept OFF when changed to an OFF state. As shown in Table 2, the specific device (for example, the first external device) may be set so that the power is not controlled by the controller 170 of the electric range and always remains in the ON state. The first external device, which must always be kept ON, can be, for example, a refrigerator. Similarly, the second external device and the third external device may be set as the second option and the third option, respectively. According to various embodiments of the present disclosure, in a specific external device, the second option and the third option may be set at the same time. For example, an external device having both the second option and the third option set may have a resume priority lower than that of the device where only the second option (suspend / resume) is selected.

As shown in the situation 1 of Table 1, the controller 170 is configured to repeat the first external device ON and the second external device to stop / resume when the first and second craters are ON and the third crater is OFF. State, the third external device can be controlled to be in the OFF state. The criteria for controlling the first to third external devices by the controller 170 may be based on setting information for each external device as described in Table 2 above.

Assuming that the output state of the crater has changed from Situation 1 to Situation 2 in Table 1, the crater replacement determination unit may determine the power control level of the external device based on the maximum output information of each crater and the remaining time of each crater. . The controller 170 may control the external device corresponding to the situation 2 as in the situation 2 (the first external device ON, the second external device ON, and the third external device stop / resume repetition) of Table 2.

When the control unit 170 determines an external device power supply control criterion, the controller 170 may determine the power consumption of each device in addition to the device-specific setting information as shown in Table 2 and perform output control.
