Description

Microwave cooking status display device and display method

The present invention relates to a cooking progress display device of the microwave oven and a display method thereof. More specifically, the cooking progress of a microwave oven which clearly informs the user of the cooking progress status of the microwave oven by controlling a lamp according to the cooking progress situation. A situation display device and a display method thereof.

In general, a microwave oven generates microwaves by applying a high-voltage electric power to a microwave oscillation tube called magnetron, unlike a conventional cooking apparatus of a conventional external heating method using heat conduction and heat radiation.

When microwave is applied to the food as described above, a lot of frictional heat is generated as the molecules constituting the food rotate at a high speed, and the food is heated and cooked by this heat.

The microwave oven has a function of notifying the user of the cooking progress by turning on a lamp while cooking is in progress and turning off the lamp when cooking is completed.

However, the method of notifying the user of the cooking progress status by simply turning on or turning off the lamp as described above has a problem that only the state of cooking and the state of cooking are displayed.

Accordingly, the present invention is to solve the conventional problems as described above, by turning on or flashing or turning off the lamp according to the cooking progress situation of the microwave oven that can be more clearly informed to the user the cooking progress situation of the microwave oven. It is an object of the present invention to provide a cooking progress display device and a display method thereof.

Microwave cooking progress display apparatus for achieving this purpose, the key operation unit for inputting the cooking environment and cooking start command according to the user's operation, the magnetron driving unit in accordance with the cooking environment and cooking start command input from the key operation unit A control unit for controlling cooking to perform cooking and at the same time dividing a cooking progress state into a cooking time, a predetermined time before completion of cooking and cooking completion, and outputting a control signal corresponding to each, a lamp for displaying a cooking progress state, and from the control unit. And a lamp driver for controlling the power applied to the lamp according to an input control signal to turn on, blink, or turn off the lamp.

In addition, the cooking progress display method of the microwave oven to achieve the above object, the step of setting the cooking environment, such as cooking time, output, starting the cooking according to the set cooking environment, the lamp to turn on Step, determining whether the remaining cooking time is less than the predetermined time, if the remaining cooking time is less than the predetermined time end determination step of determining whether the cooking is finished, if the cooking is finished, the lamp is turned off, and cooking is not finished If not, characterized in that consisting of the step of flashing the lamp until the end of cooking.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a cooking progress status display apparatus of a microwave oven according to the present invention. The cooking progress display apparatus of a microwave oven according to the present invention includes a key operation unit 1, a door opening and closing detection unit 2, It is comprised including the magnetron drive part 3, the lamp drive part 4, the lamp 5, and the control part 6. As shown in FIG.

The key operation unit 1 is configured to input a cooking environment and a cooking start command set by a user's operation to the control unit 6, and the door opening / closing detection unit 2 detects an opening / closing state of the cooking chamber door and controls the control unit 6. ).

The magnetron driving unit 3 generates a microwave by driving the magnetron under the control of the controller 6, and heats and cooks the food by applying the generated microwave to the food.

The control unit 6 generates a microwave by controlling the magnetron driving unit 3 according to a cooking environment command and a cooking start command input through the key manipulation unit 1, and the generated microwaves are applied to the food placed in the cooking chamber. Heat and cook the food.

In addition, the control unit 6 divides the cooking progress state into cooking time, a predetermined time before cooking completion, and cooking completion, and outputs a control signal corresponding to each to the lamp driver 4.

The lamp driver 4 includes a relay, and controls the power applied to the lamp 5 according to a control signal input from the controller 6 to turn on, flash, and turn off the lamp 5 to control the cooking progress. Mark it for the user's knowledge.

On the other hand, the cooking progress status display method of the microwave according to the present invention, as shown in Figure 2, the step of setting the cooking environment, such as cooking time, output, etc., and the step of starting cooking according to the set cooking environment (S2), the step of turning on the lamp (S3), the step of determining whether the remaining cooking time is less than the predetermined time (S4), if the remaining cooking time is less than the predetermined time end determination step of determining whether the cooking is finished ( S5), the step of turning off the lamp when cooking is finished (S6), and if the cooking is not finished, the lamp blinks and repeats the end determination step (S5) (S7).

The cooking progress display apparatus and the display method of the microwave oven according to the present invention configured as described above are described in detail.

A user inputs a cooking environment such as cooking time, output of a magnetron, etc. to the controller 6 through the key control unit 1, and then inputs a cooking start command to the controller 6 (S1, S2).

When the cooking start command is input as described above, the control unit 6 controls the lamp driving unit 4 to turn on the lamp 5, and operates the magnetron driving unit 3 according to the cooking environment input through the key operation unit 1. Control to start cooking food (S3).

Subsequently, it is determined whether the remaining cooking time is smaller than a predetermined time (eg, 10 seconds to 15 seconds), and when it is smaller than the predetermined time, it is determined whether the cooking is finished (S4, S5).

Subsequently, when the cooking is finished, the control unit 6 controls the lamp driving unit 4 to turn off the lamp 5, and when the cooking is not finished, the control unit 6 controls the lamp driving unit 4 until the cooking is finished, and then the lamp 5 ) Flashes.

That is, as shown in the timing diagram of FIG. 3, the lamp 5 is turned on during cooking, the lamp 5 flashes for a predetermined time before cooking is completed, and the lamp 5 is turned off after cooking. .

As described above, according to the present invention, by turning on or flashing or turning off the lamp according to the cooking progress, the cooking progress of the microwave can be further subdivided to clearly inform the user.
