Description

Microwave Auto Cooking Menu Cooking Data Control

The present invention relates to an automatic cooking menu cooking data adjusting apparatus for a microwave oven, and more particularly, to an automatic cooking menu cooking data adjusting apparatus for a microwave to change an environment of a cooking menu programmed in a microcomputer.

Generally, electronic products such as microwave ovens, electric cookers, electric frying pans, electric ovens, and rice cookers that heat and cook foods use a thermostat or a temperature fuse to prevent the product from overheating during use. For example, a microwave oven among the products using such a thermostat or a temperature fuse will be described in more detail as follows.

That is, the microwave oven is configured to place food on a tray in a cooking chamber and irradiate the high frequency generated from the magnetron into the cooking chamber so that the food is heated and cooked by the high frequency. The tray is rotated by a motor to cook the high frequency. It is configured to be cooked well by being irradiated with water uniformly.

In addition, a microwave oven that heats and cooks food by only a high frequency of the microwave oven is a single-function microwave oven, and a microwave oven having various functions such as a grill, an oven function, and a BBQ function by a high frequency heater and a convection pan is a multifunctional microwave. A microwave oven is divided into a cooking chamber and an electric battle room, and a tray, a heater, and a barbecue bar are installed in the cooking chamber.

In addition, the electric chamber is provided with a high voltage transformer for generating a high voltage, a magnetron for applying a high voltage by the high voltage transformer to emit a high frequency (microwave), and a waveguide for guiding the high frequency generated from the magnetron to the cooking chamber. Magnetron has a high temperature during operation, which may cause overheating.Therefore, a cooling fan to cool it and a duct to induce the wind of the cooling fan to the inside of the cooking chamber to discharge the steam generated during cooking to the exhaust port are installed in the electrical room. do.

Such a microwave oven has an automatic cooking method and a manual cooking method according to the cooking method, and the present invention relates to the automatic cooking method.

The automatic cooking method inputs information about various dishes to the microcomputer and selects the dish, and the cook is cooked according to information such as cooking time and fire power for the dish.

1 is a view schematically showing an automatic cooking menu cooking data adjusting apparatus of a microwave oven according to the prior art.

The conventional automatic cooking control device 10 comprises a display unit 14 and a key input unit 14 around the microcomputer 12, the analog / digital input port (A / D1) of the microcomputer 12 An external power supply + 5V is distributed and connected to the resistor R and the variable resistor RX.

Accordingly, when the user adjusts the variable resistor RX, a voltage is applied from the + 5V to 0V through the analog / digital input port A / D1 of the microcomputer, and thus the microcomputer according to the applied signal. The cooking time is adjusted according to the set data value.

According to the above-described conventional technique, there may be an advantage that the cooking time may be adjusted during cooking, but when it is not the cooking menu selected through the key input unit 14, it is impossible to adjust the cooking data. There was a problem that the scope of application of the microwave oven was very narrow.

Therefore, an object of the present invention is to solve the above problems, and to automatically change the environment of the cooking menu programmed in the microcomputer by selecting an item to change the data by diversifying the input port into the microcomputer It is to provide a menu cooking data control device.

An object of the present invention is to adjust the automatic cooking of a microwave oven comprising a key input unit for allowing a cook to select a cooking item, a microcomputer to which a signal selected by the input unit is applied, and a display unit to display information according to the signal output from the microcomputer. In the apparatus, the microcomputer is a cooking time adjusting unit for connecting an external power supply of + 5V to the resistor and the variable resistor and connected to the analog / digital port (A / D1); The power supply is distributed from the + 5V to the resistor and the variable resistor together with the cooking time adjusting unit and connected to the analog / digital port (A / D2).
