How to display / change the output of the microwave oven

The present invention relates to a method for displaying / changing an output of a microwave oven, and more particularly, when a microwave (M / W) key is pressed during operation in a manual microwave function state, an output set for 3 seconds is automatically displayed, and the output level thereof is changed. It is to provide a method of displaying / changing the output of a microwave oven in which the output is changed during operation when the M / W key is pressed while being displayed.

In general, a microwave oven is an electronic device that cooks food by using a high frequency oscillated from a magnetron, and has a thawing function, a warming function, and a cooking function by a multi-stage output of the magnetron.

In addition to the magnetron, there is a grill cooking function using a heater and a combination function using a heater and a magnetron at the same time, and an oven function of circulating hot air inside the cooking chamber with a convection heater and a convection pan installed at the rear of the cooking chamber.

In such a microwave oven, a cooking method is a sensor type automatic cooking control method that detects humidity generated from a food product by heating using a humidity sensor and automatically controls cooking time, and cooking amount according to cooking name and serving. There is a program type automatic cooking control method that finds the cooking time set by experiment in advance and controls the heating during the cooking time by manually inputting.

In order to cook in a microwave oven, put the food into the cooking room with the power connected, close the door, select the output level, select the cooking function, press the start key, and the magnetron will start under the control of the microcomputer. To cook.

These microwave ovens are diversified in their functions, and are being developed day by day to get closer to the user's preference.

In this general microwave oven, when the user sets the power during manual operation, the oven bar is turned on and the power level is displayed on the display, and when the cooking time is set, the power level is cleared and the time set by the user is displayed. . In such a state, when the user presses the start key, the stove performs an operation. In this case, only the time is displayed on the display.

That is, the general microwave oven memorizes the power level continuously during the cooking operation since the power level is displayed when the user sets the power level during the manual function operation, and then the displayed power level is erased when the user sets the cooking time. Unless you really know what the power level was there was a disadvantage.

In this case, the actual user selects the power level, but when the cooking starts, the power level is cleared, so the exact power level is not known, and the food is often overcooked or uncooked.

In addition, if the power level is changed during the cooking operation, the power level must be set again after canceling the cooking, which is also a problem for the user.

Accordingly, an object of the present invention is to solve a conventional problem, and when the microwave (M / W) key is pressed during operation in the manual stove function state, an output set for 3 seconds is automatically displayed and the output is displayed as M /. The present invention provides a method of displaying / changing the output of a microwave oven in which the output is changed during operation by pressing the W key.

The object of the present invention, the step of proceeding to cook when operating the start key after setting the stove output and the cooking time in the state set the manual stove function by the M / W key; Pressing the M / W key during the cooking to display a previous power level for a set time; and operating the M / W key while the power level is being displayed; changing the power level according to the manipulation amount. It is achieved by running sequentially.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram of a microwave oven to which the present invention is applied, reference numeral 10 denotes an M / W key for setting a manual function or changing an output level during operation, and reference numeral 20 denotes a function such as thawing and automatic cooking. A key input unit is provided with a plurality of keys for selection and time setting.

Reference numeral 30 denotes a microcomputer for controlling the entire microwave operation according to the function set by the M / W key 10 and the key input unit 20, and reference numeral 40 denotes an oscillation under the control of the microcomputer 30. The magnetron generates an electromagnetic wave for cooking, and 50 is a display unit for displaying an output level, a cooking time, and the like.

2 is a control flowchart illustrating a method of displaying / changing an output of a microwave oven according to the present invention. As shown in the figure, a step (S1) of setting a manual function and setting a stove output by operating the M / W key, a step of inputting a start key (S2), a step of cooking (S3), and M during cooking Checking whether the / W key is input (S4), displaying the power level for a set time when the M / W key is operated during the cooking (S5), while the M / W key is displayed while the power level is displayed. If it is manipulated, the step of changing the range output (S8), and if the M / W key is not operated while the power level is displayed, and performs the previous operation (S7).

With reference to the microwave oven according to the present invention having such a configuration will be described in detail with reference to Figure 2 attached to the output display / change method which is a preferred embodiment of the present invention.

First, in order to cook food, the user puts food on the turntable in the cavity, closes the door, and operates the M / W key 10. Then, the microcomputer 30 recognizes that it is a manual cooking function. At this time, when the user sets the cooking time through the key input unit 20 and presses the start key (S1), the microcomputer 30 temporarily displays the display unit 50. After displaying the power level set by the user, the displayed output level is erased and the cooking time set by the user is displayed. At the same time, the microcomputer 30 controls the magnetron 40 to be at the power level set by the user and starts cooking (S2) (S3).

If the user operates the M / W key 10 while the cooking is performed in the above process, the microcomputer 30 displays the power level initially set by the user through the display unit 50 for 3 seconds (S5). ).

As described above, when the user operates the M / W key 10 again while the output level previously set by the user is displayed, the microcomputer 30 recognizes that the output of the range is changed and the power operated by the user. At the same time as the output is changed according to the level it is displayed through the display unit 50 for a predetermined time (S8).

That is, if the user operates the M / W key 10 during cooking, the previously selected power level is displayed for a set time, and the user operates the M / W key 10 again while the set power level is displayed. In this case, the output of the range is changed to correspond to the operation, and the output level that is changed at the same time is displayed.

For example, if the user sets the high level of the microwave oven, P-Hi is displayed on the display unit, and when the power 90 of the microwave oven is selected, the P-90 is displayed on the display unit. P-10 is displayed.

In other words, the current power level is displayed during the cooking operation, and the power can be changed freely during the cooking operation.

On the other hand, if the user does not operate the M / W key 10 in the state of displaying the set power level for 3 seconds in the step (S6), the microcomputer 30 is operated by the user to know only the current power level. Judgment is made, and the cooking proceeds while maintaining the previous power without changing the power (S7).

As described above, according to the present invention, when the M / W key is operated during the operation of the microwave, the present invention can display the power level currently being output, and also operate the M / W key while the current power level is displayed. This will allow you to freely change the power level output during cooking.
