The present invention relates to a lamp of a microwave oven and a control method thereof, and more particularly, to a lamp and a control method of a microwave oven to perform a lighting function using the lamp of the microwave oven.

In general, the microwave oven is configured to cook food by directly heating the food placed inside the cooking chamber by a high frequency radiated from the magnetron provided in the electrical equipment room.

In addition, a microwave oven having a grill oven function for cooking various foods has been developed, and various dishes can be made using high-frequency energy irradiated from the magnetron and heat of a heater installed in the cooking chamber.

Such microwave ovens are widely used in general homes and restaurants as the income level increases and the life is improved, and they are used in various ways to cook or cook food.

In general, in the living room, kitchen or restaurant hall of the home where the microwave is located, the general lighting is turned off in the middle of the night when human activity is reduced, and only the night lighting which is lower in brightness than the general lighting is turned on in case of sudden activities at night. In order to turn on or off the night light, the user needs to turn on or turn off the switch by directly moving to a switch for controlling the night light.

In addition, when the user forgets the night light is turned on, the night light is turned on for a long time, causing unnecessary power consumption, and the night light needs to be purchased separately, thus causing unnecessary costs.

On the other hand, in the electric room of the microwave oven is a lamp of the microwave because the user is provided with a lamp to provide a light to help when the user puts or removes food in the cooking chamber of the microwave in order to cook food It can be used as a night light, but relatively high power consumption is required to keep the lamp on for a long time, and the brightness of the lamp is too dark to be used as a night light.

Therefore, there is a timer function, the user can turn on or off automatically without the need to adjust the switch directly, the night light that reduces power consumption will be required.

Accordingly, an object of the present invention is to install a light emitting diode in which the power consumption is reduced in order to solve the above-mentioned problems in the front of the microwave oven, and to perform an illumination function using the light emitting diode. It is to provide a lamp and a control method thereof.

Still another object of the present invention is to adjust the on / off timing of the lamp to perform the night light function according to the user's setting, and automatically turn on / off the lamp by selecting the night light function programmed or set in the microwave. The present invention provides a lamp control method of a microwave oven capable of setting a timing.

In order to achieve the above object, the lamp of the microwave oven according to the present invention, the input unit for setting and input the cooking conditions of the food, the microcomputer for controlling the operation of the microwave, the input operation command and operation state The display unit for displaying the display so that the user can see, a driver for performing the operation of the microwave in response to the control signal of the microcomputer, and a lamp unit formed in the front end of the microwave oven, the lamp unit timer operation It is composed of a light emitting diode which is automatically turned on / off to perform an illumination function.

In addition, the timer operation is characterized in that the on / off timing of the lamp is set by the user, or by selecting a program or a set timing in the microwave.

In addition, the light emitting diode has a rated current of about 8 mA, consumes about 90 mW to about 100 mW, and uses a light emitting diode having a brightness of about 6000 mcd to about 7000 mcd, and is located on one side of the front side of the microwave oven. It is characterized in that formed on top of the display unit.

In order to solve the above technical problem, the lamp control method of the microwave oven according to the present invention comprises the steps of the user selecting the lamp mode, the user selects the operating time of the lamp programmed in the microwave or input the lamp operating time And turning on the lamp by generating a control signal in the microcomputer when the turn-on time of the set lamp is reached, and performing a lighting function by turning off the lamp by generating a control signal in the microcomputer when the set turn-off time is reached. Characterized in that it comprises a step.

In addition, a program screen divided at predetermined time intervals is provided when selecting the ON / OFF of the programmed lamp of the microwave oven, and the ON / OFF time setting of the lamp sets the lamp turn on and turn off time using an input key. Or by setting the turn-on time and the lighting time.
