Abstract

PROBLEM TO BE SOLVED: To permit the cooking of scorched rice simply under the optimum condition by a method wherein the weight of rice is detected and the rice is heated by a cooking time optimum to the detected weight of rice to cook the scorched rice. SOLUTION: A weight detecting sensor 20 detects the weight of rice, filled into a cooking vessel, and the cooking time of scorched rice, corresponding to the weight of rice in the cooking vessel, is operated by a weight signal, corresponding to the detected weight of rice, then, a timer, accommodated in a microwave oven, is reset to count a cooking time. Next, a control unit 60 judges whether the time, counted by the timer, is abnormal or not compared with the operated scorched rice cooking time and when the scorched rice cooking time has elapsed, the generation of microwaves from magnetron 40 is stopped and a control signal for interrupting the cooking operation of scorched rice is outputted. According to the signal, the generation of the microwaves is interrupted and the cooking of the rice in the cooking vessel is finished under the condition that the scorched rice is cooked under the optimally browninged condition.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven that heats and cooks food by generating microwaves, and more particularly, to a method for scorching a microwave oven suitable for automatically cooking.

[0002]

2. Description of the Related Art In general, a conventional method of burning charcoal is to cook rice using a conventional cooking mechanism (for example, a gas range) that heats the bottom of a cooking vessel or to cook already cooked rice. It was to cook the charcoal by putting it in a cooking vessel, adjusting the heating power manually, and causing the rice to scorch on the bottom of the cooking vessel.

[0003] However, the conventional charcoal cooking method as described above has the inconvenience that the user has to manually adjust the heating power, and the characteristics of the conventional cooking mechanism for heating the bottom of the cooking vessel are inconvenient. If the heating power cannot be properly adjusted, there is a problem that the current situation of scorching frequently occurs.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention has been devised to solve the above-mentioned problems of the prior art, and the present invention is directed to a microwave dielectric heating characteristic and an automatic microwave oven. It is an object of the present invention to provide a charcoal cooking method for a microwave oven, which can automatically cook charcoal in an optimum state by automatically cooking charcoal using a cooking function.

[0005]

According to a first aspect of the present invention, there is provided a method for scorching and cooking a microwave oven using microwaves to heat food in a cooking chamber using microwaves. Positioning the cooking vessel filled with rice in the cooking chamber, sensing the weight of the rice loaded in the cooking vessel, and detecting the weight of the rice. A cooking time calculating step of calculating a burning time to be burned, and a burning cooking step of generating microwaves and cooking the burning during the calculated burning time.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Figure 1
FIG. 2 is a schematic block diagram of hardware configured to perform the method of scorching a microwave oven according to the present invention. As can be seen from the drawing, the hardware includes a key input unit 10 and a weight sensor 20. , A magnetron drive unit 30, a magnetron 40, a buzzer 50, and a control unit 60.

In FIG. 1, a key input unit 10 includes a number of keys for controlling various functions of a microwave oven. The key input unit 10 converts a key operation by a user into an electric key signal corresponding to the key operation. , The weight sensor 20 detects the weight of the food in the cooking chamber (not shown) and inputs a corresponding weight detection signal to the controller 60.

The control unit 60 generates a cooking control signal for performing a cooking operation based on the key signal input from the key input unit 10 and the weight of the food detected through the weight sensing unit 20, and drives the magnetron. On the other hand, an end sound control signal for generating a cooking end sound is generated and input to the buzzer 50 while being input to the section 30.

Incidentally, the magnetron driving unit 30 includes the control unit 6
A power supply voltage (not shown) externally input by a cooking control signal input from 0 is transformed into a high voltage (for example, about 2 [KV]) of a predetermined level suitable for generating microwaves and input to the magnetron 40. The magnetron 40 generates a microwave using the high voltage input from the magnetron driving unit 30, and radiates the microwave into the cooking chamber through a waveguide (not shown). The buzzer 50 generates a cooking end sound in response to an end sound control signal input from the control unit 60.

The operation of the present invention will be described in detail with reference to FIGS. 1 and 2 through the hardware configured as described above. First, in a state where a cooking container filled with a predetermined amount of rice is placed in a cooking chamber (not shown), the control unit 60 sends a key signal for instructing browning to the key input unit 1.
It is repeatedly determined whether the input is started from 0 (S1). At this time, when the user operates the selection key of the key input unit 10 which instructs the burning, the corresponding key signal is issued. Is input from the key input unit 10 to the control unit 60. The control unit 60 generates a microwave to generate a control signal for starting a cooking operation, and inputs the control signal to the magnetron driving unit 30.

With this, the magnetron drive unit 30 changes a power supply voltage (not shown) input from the outside into a high voltage (for example, about 2 [KV]) suitable for generating microwaves by a control signal input from the control unit 60. After transforming to
This is input to the magnetron 40.

Then, the magnetron 40 generates a microwave using the high voltage inputted from the magnetron driving unit 30, and radiates the microwave through the waveguide (not shown) to the inside of the cooking chamber. Start heating the rice in the container.

At this time, the weight sensing sensor 20 senses the weight of the rice put in the cooking container, and the weight is put in the cooking container according to the weight signal input from the corresponding weight sensing sensor 20. After calculating the burning time corresponding to the weight of the rice, the built-in timer is reset and the time is counted (S4).

For reference, the weight of rice put in the cooking container is approximately 200 g [g], and the electric power input to the magnetron 40 from the magnetron driving unit 30 is 700.
On the basis of the case of watts [W], the above-mentioned scorched cooking time is about 18 minutes.

Next, the control unit 60 determines whether or not the time counted by the timer is equal to or longer than the burnt cooking time calculated in the step (S4), that is, whether or not the burnt cooking time has elapsed. The determination is repeated (S5), and when the above-described scorching cooking time has elapsed, a control signal for stopping generation of microwaves and interrupting the scorching cooking operation is generated (S6).

As a result, the magnetron driving unit 30 interrupts the input of the high voltage to the magnetron 40, and the magnetron 40 interrupts the generation of the microwaves as the input of the high voltage from the magnetron driving unit 30 is interrupted. As a result, the cooking is finished in a state where the rice put in the cooking container is browned in an optimal state, that is, the rice is cooked in a scorched state.

The control unit 60 generates an end sound control signal for outputting a cooking end sound and inputs the signal to the buzzer 50. The buzzer 50 generates a cooking end sound according to the end sound control signal input from the control unit 60. Output.

As described above, according to the present invention, the scorch is achieved by sensing the weight of the cooked rice, heating the cooked rice for an optimal cooking time based on the sensed weight of the cooked rice, and cooking the scorch. It has the effect of being able to cook easily and optimally.
