Referring to FIG. 3, an electric burner 111 is formed in the electric cooktop 110, and an operation unit 140 and an RF (radio frequency) transmitter 150 are installed.

The electric burner 111 is a device that uses electricity as an energy source and transfers heat to a heat source through a heat source that utilizes a heat generating function of a current to cook food while heating the cooking vessel. As the heat source used here, a highlight heater, a coil type radiant heater, a halogen heater, or the like can be used. A ceramic glass plate or the like having a high heat resistance is provided on the electric burner 111.

A plurality of electric burners 111 are provided and have different areas. In the present embodiment, three electric burners 111 are provided, 111a, 111b, and 111c, respectively, and have different areas to generate different amounts of heat. In this embodiment, the electric burner 111 having the largest area is referred to as a first electric burner 111a, and the second electric burner 111b and the third electric burner 111c are referred to as an area size in this order.

A second electric burner 111b and a third electric burner 111c are disposed on the upper side and the lower side respectively on the left side of the electric burner 111. A first electric burner 111a is provided on the post of the electric burner 111 .

The hood 120 is disposed above the electric cooktop 110 for forcibly discharging contaminants (excess heat, odor, and oil vapor) generated during cooking and cooking to the outside. The hood 120 includes a plurality of ventilation portions 130. The number of the ventilation units 130 is not limited and may be appropriately selected. In the present embodiment, however, two ventilation units 130 are provided, and are disposed to correspond to the left side of the electric burners 111 and the postal system. That is, one ventilation part 130 corresponds to the first electric burner 111a and the other ventilation part 130 corresponds to the second electric burner 111b and the third electric burner 111c .

Each of the ventilation portions 130 includes a blowing fan 131, a motor 132, and an exhaust pipe (not shown). At this time, the blowing fan 131 of each ventilation part 130 and the exhaust pipe (not shown) may be provided in the same manner. However, the motor 132 is provided so as to drive the respective blowing fans 131 and to have different exhaust amounts. The blowing fan 131 is driven by a motor 132, and the motor 132 is driven by a control unit 160. Here, a motor having a relatively large rotational force is referred to as a first motor 132a, and a motor having a relatively small rotational force is referred to as a second motor 132b. The first motor 132a and the second motor 132b can be selectively driven by the controller 160 and the selection of the appropriate motor 132 and the rotational speed of the motor 132 are determined according to the amount of exhaust required . More detailed information will be described later.

The operation unit 140 is configured to control the driving of the electric cooktop 110 and the hood 120 and the intensity of the thermal power of the electric cooktop 110 electric burner 111. In this embodiment, the operation unit 140 is installed in the electric cooktop 110, and the operation unit 140 includes a burner control unit 141, an intensity control unit 142, and a hood control unit 143. In this embodiment, the operation unit 140 is provided so as to be driven by a user's depression.

The hood adjuster 143 is configured to control the respective ventilation units 130. [ The hood adjuster 143 is provided with a single button. In this embodiment, when the user presses the hood adjuster 143, the motor 132 having a relatively large rotational force is driven. When the user presses the hood adjuster 143 twice, the motor 132 having a relatively small rotational force is driven. All of the motors 132 are driven. The pressing number information of the hood adjusting section 143 reaches the control section 170 through the RF transmitting section 140 and the RF receiving section 150 and the control section 170 controls the respective motors 132 .

However, the rotational speed of each motor 132 is not changed through the hood adjusting part 143. [ That is, the rotational speed of each motor 132 is automatically converted through the control unit 170, but the hood adjusting unit 143 does not have a function of changing the rotational speed of the motor 132. [

The RF transmitting unit 140 and the RF receiving unit 150 are configured to transmit a signal of the operating unit 140 to the control unit 170. [ The RF transmitting unit 140 transmits information on the number of times of pressing of the hood adjusting unit 142 and the information on the thermal power intensity of each electric burner 111 in a radio frequency format and transmits the information to the RF receiving unit 150 do. This information is transmitted to the control unit 170.

The control unit 170 controls whether or not the motor 132 is selectively driven and the rotational speed of each motor 132 based on the above-described information.

For example, when the user drives the electric burner 111 having the largest area and presses the hood adjusting part 143 once, this information is transmitted to the RF transmitting part 140 and the RF receiving part 150 The control unit 170 drives the motor 132 having a relatively large rotational force in this case.

When the user controls the intensity of the thermal power of the electric burner 111 by pressing the intensity controller 142, this information is also transmitted to the controller 170 through the RF transmitter 140 and the RF receiver 150 . The control unit 170 adjusts the rotation speed of the motor 132 according to the strength of the thermal power, and accordingly, it has an appropriate amount of exhaust according to the strength of the thermal power. For example, when the electric power of the electric burner 111 is 1 to 3 stages, the first motor 132a is 1 stage, when the thermal power is 4 to 6 stages, the first motor 132a is 2 stages, In case of the 9th stage, the first motor 132a may be driven in three stages.

When the user presses the hood adjuster 143 twice, the motor 132 having a relatively small rotational force is driven. All of the motors 132 are driven.

The thermal power control step S130 is a step of adjusting the thermal power intensity of the electric burner 111. [ The user is controlled through the intensity adjustment unit 142. The thermal power of the electric burner 111 varies depending on the number of presses of the intensity controller 142.

In the information transmission step S130, the pressing information of the user in the hood driving step S120 is transmitted to the control unit 170, and in the hood control step S140, the control unit 170 controls the hood 120. [

If the user presses once, the pressing information of the hood adjusting part 143 is transmitted to the controller 170 through the RF transmitting part 150 and the RF transmitting part 150, and the controlling part 170 has the largest area And drives the motor 132 of the ventilation unit 130 disposed above the electric burner 111 having the electric motor.
