The present invention relates to a lamp control method of a microwave oven, and more particularly, to a lamp control method of a microwave oven to perform a lighting function using a 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. Therefore, as the usage of the microwave oven increases, the plug of the microwave oven is always connected to an outlet to which power is supplied, and when necessary, only the operation key of the microwave oven is pressed to operate the microwave oven in general.

In the electric room of the microwave oven, when a user performs a process of putting or removing food into the cooking chamber of the microwave in order to cook food, a lamp is provided to provide illumination to help this. The lamp maintains a turn-off state when the door of the microwave oven is closed, and turns on when the door of the microwave oven is opened, and serves to assist food intake by providing lighting of a predetermined brightness in the cooking chamber.

On the other hand, in the living room, kitchen or restaurant hall of the home where the microwave is generally 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 prepared for sudden activities at night. In order to turn on or off the night light, the user needs to go directly to the switch for adjusting the night light to turn on or turn off the switch. In addition, when the user forgets the state in which the night light is turned on, the night light is turned on for a long time, which causes unnecessary power consumption.

Therefore, a night light with a timer function is installed so that the user does not need to adjust the switch directly, and a night light that can be turned on or off automatically will be requested.

Accordingly, an object of the present invention is to provide a lamp control method of a microwave oven that can perform a lighting function by using a lamp of a microwave oven that can be operated using a timer to solve the above-mentioned conventional problems.

Another object of the present invention is to adjust the on / off timing of the lamp to perform the lighting function according to the user's setting, it is possible to automatically set the on / off timing of the lamp by selecting the lighting function programmed or set in the microwave. The present invention provides a lamp control method of a microwave oven.

In order to achieve the above object, the lamp control method of the microwave oven according to the present invention,

Selecting a lamp mode by a user;                     

A user selecting an on / off time of a lamp programmed in a microwave or inputting a lamp operating time; And

Performing a lighting function by turning on the lamp by generating a control signal in the microcomputer when the turn-on time of the set lamp is reached, and turning off the lamp by generating a control signal in the microcomputer when the set turn-off time is reached. Include.

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 is performed by using an input key. Or the lamp operation timing is set by inputting a turn-on time and a lighting time.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The descriptions in the various embodiments are only shown and limited by way of example and without intention other than the intention to help those of ordinary skill in the art to more thoroughly understand the present invention, and thus the scope of the present invention. It should not be used as a limitation.

The microwave oven according to the present invention includes an input unit 110, a microcomputer 120, a display unit 130, a driving unit 140, and a lamp unit 150.

The input unit 110 is composed of input keys for setting and inputting various conditions such as cooking selection, cooking time, operation start and end of the microwave. In addition, the input key may include a lamp mode setting key for selecting or setting the on / off time of the lamp.

The microcomputer 120 includes a programmable microcomputer having a RAM capable of temporarily storing data and a ROM capable of storing a program. The microcomputer 120 displays an operation command input from an input unit on the display unit, and stores a program for operating the driving unit 140 and the lamp unit 150 according to the operation command.

Therefore, when the lamp mode is selected, the microcomputer 120 may be programmed to automatically set the on / off time of the lamp. In addition, the user can select the lamp mode, and adjust the on / off time of the lamp by setting the on / off time of the lamp using a timer. In addition, in addition to the on / off time of the lamp may include a function to adjust the brightness of the lamp.

The display 130 displays an input operation command and a state in which the operation is in progress so that the user can see it.

The driving unit 140 performs a cooking operation of the microwave, including a component for cooking food such as a magnetron, a cooling fan, and a driving motor.

The lamp unit 150 is installed in the electric room of the microwave oven, is maintained in the turn-off state when the door of the microwave oven is closed, and turned on when the door of the microwave oven is opened to provide illumination of a predetermined brightness in the cooking chamber It is responsible for the introduction of food.

In addition, in the present invention, by turning on or off in response to the control signal of the microcomputer 120 may perform the function of a night light. Thus, the lamp unit is set by the user directly, or operate according to the programmed on / off time.

2 is a perspective view illustrating a microwave oven according to the present invention, FIG. 3 is a view illustrating an input unit of the microwave oven of FIG. 1, and FIG. 4 is a circuit diagram illustrating a lamp unit of the microwave oven of FIG. 1. Referring to Figure 4 specifically look as follows.
