The power supply unit 100 supplies electric power to the electric range.

At this time, the maximum power supplied shall not exceed 4.3 kW, the capacity of the switchboard of the house.

The furnace portion 200 has a plurality of furnaces 210, 220, and 230 having different power consumption, and generates heat based on the power supplied from the power supply portion 100.

At least one of the fireboxes 200 may vary the range of heat generation depending on the size of the container used for cooking.

For example, when a small-sized container is used, the radius of the crater generating heat can be reduced, and when the large-sized container is used, the radius of the crater generating heat can be increased.

The input unit 300 may be any one of a touch panel, a touch pad, and a touch screen. The input unit 300 may include an input for turning on / off, a lock function, And converts them into electric signals to output command signals CMD.

The power measuring unit 400 measures the power consumption of each of the plurality of culverts 210, 220 and 230 in the crater unit 200 and outputs a power consumption signal.

The control unit 500 receives command signals CMD from the input unit 300 and controls turn on / off of the electric range and input lock of the input unit 300, 210, 220, and 230 to select and operate a crater to be used in the crater unit 200 and to control the thermal power of the selected crater.

The switching unit 600 includes a plurality of switches SW1 to SW3 and is responsive to the control signal of the control unit 500 to control the power supply unit 100 and the plurality of culverts 210, 230 are selectively short-circuited.

3 is a flowchart showing a power control method of an electric range according to an embodiment of the present invention.

The operation of the electric power control method of the electric range according to the embodiment of the present invention will be described with reference to FIGS. 1 to 3, as follows.

First, the present embodiment assumes that the firebox unit 200 is composed of a fire extinguisher 210, a fire extinguisher 220, and a communicator 230 with rated power consumption of 1.1 kW, 1.4 kW, and 1.8 kW, respectively.

The input unit 300 detects an input to a crushing button of a turn-on button, a fire extinguisher 210, a fire extinguisher 220 and a fire extinguisher 230 through a finger touch of a user and converts the input into an electric signal And outputs a turn-on command signal and a fire fighting command signal (S110).

In response to the turn-on command signal, the control unit 500 turns on the electric range in response to the turn-on command signal and the fire making selection command signal from the input unit 300, 1 to the third switches SW1 to SW3 (S120).

The first to third switches SW1 to SW3 in the switching unit 600 are short-circuited in response to the switch control signal of the control unit 500 and connected to the power supply unit 100, the fire extinguisher 210, The neutralizer 220 and the communication hole 230 are electrically connected to each other (S130).

The power supply unit 100 supplies power to the fire extinguisher 210, the fire extinguisher 220 and the fire extinguisher 230 in the fire extinguisher unit 200 at step S140.

The power measuring unit 400 measures the power consumption of each of the fire extinguisher 210, the fire extinguisher 220 and the communication unit 230 in the firebox unit 200 and outputs the first to third power consumption signals (S150 ).

The control unit 500 receives the first to third power consumption signals from the power measuring unit 400 and controls the first to third thermal power control units And outputs a signal (S160).

The fire extinguisher 210, the fire extinguisher 220 and the fire extinguisher 230 in the firebox unit 200 respond to the first to third firepower control signals of the control unit 500 in response to the electric power supplied from the electric power supply unit 100 Thereby generating heat.

If the three fire engines 210, 220, and 230 are used at the same time, the fire engines of the fire engines 200 are configured to be able to adjust the fire power in nine stages. Therefore, the total power consumption is set to 3.5 kW To limit the amount of power.

Accordingly, the first thermal power control signal reduces the rated power consumption of the fire extinguisher 210 to 1.1 kw to 0.5 kw, which is the first fire power of the fire extinguisher 210, and restricts the fire power control step to 5th, 7th, (S170).

In addition, the second thermal power control signal maintains the thermal power control step at the 9th step, but reduces the rated power consumption of the neutralizer 220 to 1.2 kw (S180).

In addition, the third thermal power control signal maintains the thermal power control step at step 9 and maintains the rated power consumption of 1.8 kw of the communication tool 230 (S190).

In this manner, the total sum (3.5 kw) of the first to third power consumption is adjusted so as not to exceed the allowable power code power value of 3.5 kw.

4 is a flowchart illustrating a method of controlling power of an electric range according to another embodiment of the present invention.

The operation of the electric power control method of the electric range according to another embodiment of the present invention will be described with reference to FIGS. 1, 2 and 4, as follows.

First, in the present embodiment, in the state where the firebox unit 200 is composed of the fire extinguisher 210, the fire extinguisher 220, and the communicator 230 with rated power consumption of 1.1 kw, 1.4 kw, and 1.8 kw, respectively, It is assumed that the thermal power of the interactive tool 230 is increased by a predetermined amount.

Generally, when 1000cc of ordinary water is boiled, it takes about 7 minutes for the maximum power of the electric range communicator 230 and about 5 minutes for the induction burner of 2.1 kw. Therefore, Can be used.

When the power of 2.1 kW is used in this way, it is preferable that the maximum power of the electric range counter 230  The turbo function of the interactive tool 230 must be used. In case of using the turbo function of the interactive tool 230, the main power of 1.8 kw is changed to the 2.1 kw power as follows.

That is, at the beginning of use, the input unit 300 detects the input to the crank button of the turbocharger 230 and the turn-on button, the fire extinguisher 210, the neutralizer 220 and the turbocharger 230 Converts it into an electric signal, and outputs a turn-on command signal and a fire fighting command signal (S210).

In response to the turn-on command signal, the control unit 500 turns on the electric range in response to the turn-on command signal and the fire making selection command signal from the input unit 300, 1 to the third switches SW1 to SW3 (S220).

The first to third switches SW1 to SW3 in the switching unit 600 are short-circuited in response to the switch control signal of the control unit 500 and connected to the power supply unit 100, the fire extinguisher 210, The neutralizer 220 and the communication hole 230 are electrically connected to each other (S230).

The power supply unit 100 supplies electric power to the fire extinguisher 210, the fire extinguisher 220 and the fire extinguisher 230 in step S240.

The power measuring unit 400 measures the power consumption of each of the fire extinguisher 210, the fire extinguisher 220 and the fire extinguisher 230 in the firebox unit 200 and outputs the first to third power consumption signals (S250 ).

The control unit 500 receives the first to third power consumption signals from the power measurement unit 400 and determines a crater to be used first (S260). If the sum of the first to third power consumption exceeds the power code power allowance And outputs a fire control signal for controlling the fire control system.

The fire extinguisher 210, the fire extinguisher 220 and the fire extinguisher 230 in the firebox unit 200 respond to the first to third firepower control signals of the control unit 500 in response to the electric power supplied from the electric power supply unit 100 Thereby generating heat.

As in the case of using the three reactors 210, 220 and 230 at the same time, the total power consumption must be limited to the power code power allowable value of 3.5 kw.

In case of using the turbo function, the total power consumption of the fire extinguisher 210 and the fire extinguisher 220, which are the remaining fire extinguishers, should be 1.4 kw or less since the total firepower of 1.8 kw is changed to 2.1 kw firepower.

Accordingly, the controller 500 outputs the first and second thermal power control signals or the third and fourth thermal power control signals so that only the fire extinguisher 210 and the neutralizer 220 are operated first (S261).

If the fire extinguisher 210 is used first, the controller 500 outputs the first and second fire control signals to operate only the fire extinguisher 210 (S261).

The first thermal power control signal maintains the thermal power control step, which is the rated power consumption of the fire extinguisher 210, at 9 steps and maintains the rated power consumption of the fire extinguisher 210 at 1.1 kw (S262).

In addition, the second thermal power control signal maintains the thermal power control step at the 9th stage but increases the rated power consumption of the communication tool 230 to 2.1 kW (S263).

On the other hand, the controller 500 outputs a switch-off signal for opening the second switch SW2 to prevent the total power consumption from exceeding the power code power allowance (S264).

The second switch SW2 is opened in response to the switch shutoff signal of the control unit 500 to cut off the electrical connection between the power supply unit 100 and the neutralization port 220 (S265).

In this manner, the total sum (3.2 kw) of the first to third power consumption is adjusted so as not to exceed the allowable power code power value of 3.5 kw.

If the neutralizer 220 is used first, the controller 500 outputs the third and fourth thermal power control signals to operate only the neutralizer 220 (S271).

The third thermal power control signal maintains the thermal power control step, which is the rated power consumption of the neutralizer 220, in nine stages and maintains the rated power consumption of the neutralizer 220 as 1.4 kw (S272).

In addition, the fourth thermal power control signal maintains the thermal power control step at the 9th step, but increases the rated power consumption of the communication tool 230 to 2.1 kW (S273).

On the other hand, the controller 500 outputs a switch-off signal for opening the first switch SW1 in order to prevent the total power consumption from exceeding the power code power allowable value (S274).

The first switch SW1 is opened in response to the switch cutoff signal of the controller 500 to cut off the electrical connection between the power supply unit 100 and the fire extinguisher 210 (S275).

In this manner, the total sum (3.5 kw) of the first to third power consumption is adjusted so as not to exceed the power code power allowable value 3.5 kw.

Therefore, since the total power consumption of the electric range according to the present invention can be used within 3.5 kW, it can save much energy compared to the conventional electric range having a power consumption of 4.3 to 5.5 kW.

As described above, the power control method of the electric range according to the present invention can measure the power consumption of the plurality of culverts of the electric range and adjust the power consumption or the thermal power adjustment step so that the total sum of the power consumption does not exceed the maximum power allowable value.

As a result, even if the hybrid type is used, it can be installed with the power cord without directly connecting to the wall power source through the construction, and even when a plurality of craters are used simultaneously, the total power consumption is automatically controlled to be within the maximum allowable value. It is possible to prevent the occurrence of an electric accident due to the heat of the electric connection port and the power consumption, and to reduce the power consumption.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the present invention can be changed.
