Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a kitchen hood control apparatus and method using an electric range,

The present invention relates to an apparatus and method for controlling a kitchen hood using an electric range that automatically controls operations of an illumination lamp and an exhaust fan provided in a kitchen hood according to the operation of an electric range.

BACKGROUND ART Gas ranges are widely used as heat sources for heating or cooking foods. Although the gas range can provide a strong thermal power, it is exposed to the risk of explosion due to gas leakage, and it is not easy to arbitrarily adjust the heating temperature of the food.

In addition, the gas range is burned, and many harmful substances such as carbon monoxide, nitrogen dioxide, sulfur dioxide, and formaldehyde are generated and pollute the room air.

An electric range capable of cooking food by using electricity as a means for eliminating the problem of the above-described gas range and providing a pleasant indoor air has been widely used.

The electric range may be classified into a hot plate electric range, a highlight electric range, and an induction electric range according to a heating method.

In the hot plate electric range, when a driving electric power is applied, a hot wire heater installed on the upper surface of the plate generates heat due to electric resistance and heats the cooking container seated on the plate. The structure is simple and relatively inexpensive.

The highlight electric range is a method in which a heater built in under a top plate of a ceramic generates heat and heats a top plate made of a ceramic material, so that a high temperature can be exhibited within a short time from the point in time when the power is turned on.

The induction electric range is an electromagnetic induction heating method that utilizes the heat generation of the cooking container itself by electromagnetic induction, and is energy efficient and has a fast cooking speed.

Unlike the gas range, the electric range does not have the danger of explosion due to the leakage of the gas, and there is no odor, and no harmful substances are generated, thus providing pleasant indoor air.

In addition, the electric range can have a combination of a hot plate electric range, a highlight electric range and an induction electric range in one body, and unlike the gas range, the appearance is simple. Especially, the upper surface can be formed in a flat appearance, It can also be easily installed in a built-in sink.

When a predetermined food is cooked while heating the cooking container using such an electric range, the food being cooked is heated, and the odor of the food itself may be generated, which may contaminate the room air.

Therefore, in the case of cooking food by heating the cooking container with the electric range, it is necessary to rotate the exhaust fan of the kitchen hood to exhaust the odor generated when the food is cooked.

As a prior art for controlling the operation of the kitchen hood when the electric range is in operation, Korean Patent Laid-Open No. 10-2016-0012849 (published on May 2, 2106) is known.

The present invention relates to an electric range equipped with a main control unit for controlling overall functions, the main control unit comprising hardware having an interface to which various devices are connected and software installed in the hardware, A display unit connected to the main control unit and informing the user of all information on the operating state of the electric range, a display unit connected to the main control unit, And a communication unit connected to the main control unit for wireless communication with the external equipment, wherein the communication unit communicates with the range hood to control the electric range according to the control of the electric range So that the range hood is operated.

In the above prior art, the electric range detects the temperature of the cooking container in the process of cooking predetermined food using the electric range, and when the temperature of the cooking container is higher than a predetermined temperature, the electric range performs communication with the range hood When the range hood is not in operation, a driving signal is transmitted to the range hood so that the range hood is driven, that is, the exhaust fan of the range hood and the illumination lamp are driven.

The lighting lamp installed in the range hood needs to be turned on only when the user visually confirms the cooking state of the food when cooking the predetermined food.

However, the above-described prior art has a problem in that unnecessary power consumption is unnecessarily consumed when the temperature of the cooking vessel is maintained at a predetermined temperature or more regardless of the presence or absence of a user.

2 is a signal flow diagram illustrating the operation of the controller according to the control method of the present invention.

The following detailed description is merely an example, and is merely an example of the present invention. Further, the principles and concepts of the present invention are provided for the purpose of being most useful and readily explaining.

Accordingly, it is not intended to provide a more detailed structure than is necessary for a basic understanding of the present invention, but it should be understood by those skilled in the art that various forms that can be practiced in the present invention are illustrated in the drawings.

1 is a block diagram showing a configuration of an embodiment of a control apparatus of the present invention. 1, the control apparatus of the present invention includes a key signal input unit 110, a temperature detection unit 120, a human body detection unit 130, a heat source 140, a heat source driving unit 150, A driving unit 160, an illumination lamp driving unit 170, and a control unit 180. [

The key signal input unit 110 may include a plurality of function keys including a power key, a thermal power control key, and a timer key, and may generate an operation command of the corresponding function key when the user operates the plurality of function keys have.

The temperature detector 120 may detect a temperature by a detection signal of a temperature sensor disposed adjacent to the heat source 140 to generate a temperature detection signal.

The human body detecting unit 130 may be provided with a human body detecting sensor for detecting a human body by infrared rays or RF (Radio Frequency) on the front surface of the electric range, and may output a human body detecting signal according to the output signal of the human body detecting sensor.

The heat source 140 uses a halogen lamp, a heat generating coil, or an induction coil. The heat source 140 heats the cooking vessel, which is seated on the upper portion, so that the food can be cooked.

The heat source driving unit 150 may operate the heat source 140 to heat the cooking vessel.

For example, when the heat source 140 is a halogen lamp, a heat generating coil, or the like, the heat source driving unit 150 can generate heat by applying AC power to the heat source 140.

In the case of the induction coil in the heat source 140, the heat source driving unit 150 supplies a high frequency electric power to the heat source 140 to generate alternating magnetic fields in the heat source 140, And the generated magnetic field can generate frictional heat in the cooking container to be heated.

The exhaust fan motor driving unit 160 drives the exhaust fan motor (not shown) provided in the kitchen hood located above the electric range to exhaust the room air by rotating the exhaust fan.

The illumination lamp driving unit 170 may turn on or off an illumination lamp (not shown) provided in the kitchen hood.

The control unit 180 may control the heat source driving unit 150 to generate the required thermal power by driving the heat source 140 according to the key signal of the key signal input unit 110. [ The control unit 180 receives the temperature detection signal output from the temperature detection unit 120 to determine the temperature of the cooking container according to the driving of the heat source 140 and controls the exhaust fan motor driving unit 160 according to the determined temperature. The exhaust fan motor of the kitchen hood is driven to rotate the exhaust fan and the operation of the electric range is stopped when the overheat is detected. In addition, the controller 180 determines whether a human body is detected by inputting a human body detection signal output from the human body detecting unit 130. When the human body is detected, the illumination lamp driving unit 170 turns on a lighting lamp of the kitchen hood, Or can be controlled to be turned off.

2 is a signal flow diagram illustrating the operation of the controller 180 according to the control method of the present invention. Referring to FIG. 2, the controller 180 determines whether a power key signal is input from the key signal input unit 110 (S200).

When a signal of the power key is input from the key signal input unit 110, the controller 180 turns on the electric power of the electric range to operate the electric range (S202).

The controller 180 receives a human detection signal output from the human detection unit 130 and determines whether a human body is detected (S204).

When the human body is detected as a result of the determination, the control unit 180 controls the illumination lamp driving unit 170 to turn on the illumination lamp provided in the kitchen hood (S206).

Therefore, after the user operates the power key from the key signal input unit 110 to turn on the power of the electric range, it is possible to visually and easily check the food to be cooked by the illumination of the lighting lamp, 110 can be operated while visually confirming the position of a plurality of function keys provided in the main body 110, so that the food can be cooked and operated.

In this state, the control unit 180 controls the electric range to be operated according to an operation command of the electric range inputted from the key signal input unit 110 (S210).

That is, the control unit 180 controls the heat source driving unit 150 according to a signal of the thermal power control key provided in the key signal input unit 110 to heat the cooking container with the thermal power required by the heat source 140. The controller 180 selects the corresponding heat source 140 among the plurality of heat sources 140 according to the operation of the heat source selection key and controls the thermal power of the selected heat source 140 And controls the heat source driving unit 150 of the heat source 140 according to the signal of the key to heat the cooking vessel with the thermal power required by the selected heat source.

In this state, the control unit 180 receives the temperature detection signal output from the temperature detection unit 120, and determines whether or not the temperature determined based on the input temperature detection signal is equal to or higher than a predetermined boiling temperature (S214).

If the determined temperature is not equal to or higher than the preset boiling temperature, the control unit 180 returns to step S204 and repeats the operation of determining whether or not a human body is detected.

When the determined temperature is equal to or higher than a preset boiling temperature, the controller 180 controls the exhaust fan motor driving unit 160 to drive the exhaust fan motor provided in the kitchen hood (S216).

The exhaust fan is rotated according to the driving of the exhaust fan motor, so that harmful substances including the smell of food or the like generated by the cooking of the food are exhausted to the outside.

The controller 180 determines whether the determined temperature is equal to or higher than a preset overheating temperature (S218).

When the temperature determined by the temperature detection unit 120 is not equal to or higher than a predetermined over-heating temperature, the controller 180 stops the operation of the electric range from the key signal input unit 110 Is input (S220).

That is, the controller 180 determines whether the signal of the power key is inputted to command the stop of the operation of the electric range while the electric power of the electric range is turned on.

If the operation stop command of the electric range is not input, the controller 180 returns to step S204 and determines whether the human body is detected by the human body detection signal output from the human body detection unit 130 Repeat from operation.

As a result of the determination, when the operation stop command of the electric range is inputted, the control unit 180 stops the operation of the electric range (S222).

Here, stopping the operation of the electric range means not stopping the electric range by completely turning off the electric power, but stopping only the operation of the heat source 140 to prevent the cooking container from being heated.

Then, the controller 180 waits for a preset time (S224). Then, the exhaust fan motor driving unit 160 drives the exhaust fan motor so that the exhaust fan of the main body hood rotates while the electric range is maintained in the power-on state for the set waiting time, Odor and other harmful substances are exhausted to the outside.

When the set time has elapsed in this state, the controller 180 controls the exhaust fan motor driving unit 160 to stop the exhaust fan (S226), turns off the power of the electric range (S228), and operates the electric range And terminates all operations.

If the temperature detected in step S218 is equal to or higher than a preset overheating temperature, the controller 180 controls the exhaust fan motor driving unit 160 to stop the exhaust fan (S230).

Here, the reason why the exhaust fan is stopped when the overheat is detected is that when the exhaust fan is rotated when the overheat due to the occurrence of the fire is detected due to the occurrence of the fire, the fire generated as the room air is exhausted to the outside diffuses There is concern.

Therefore, in the present invention, when the overheat is detected, the exhaust fan motor is stopped to prevent the exhaust fan from rotating, thereby reducing the diffusion speed of the fire generated in case of overheating due to the occurrence of fire.

After the exhaust fan motor is stopped, the controller 180 turns off the power of the electric range (S232), and ends the operation of operating the electric range.
