Abstract

PROBLEM TO BE SOLVED: To enable optimum cooking of material to be cooked by a method wherein time is counted until the temperature of a temperature sensor reaches a reference temperature along a cooking course and a treatment is performed to heat the material to be cooked while the time covers a residual cooking time set along the cooking course of a user. SOLUTION: After a user selects a cooking course through a key input part 20, with an input for the start of cooking, a key input part 20 outputs a corresponding key signal to a control section 30. In this process, a temperature sensor 22 senses temperature within a cooking chamber to be outputted to the control section 30. The control section 30 judges whether the temperature reaches a reference temperature or not and when the reference temperature is determined to be reached, the counting of time is started. The control section 30 judges whether the counted time is over the residual processing time or not and when the residual processing time is determined to be over, a control signal is outputted separately to a turntable motor driving part 40, a magnetron driving part 42 and a cooling fan motor driving part 44 to stop a turntable motor, a magnetron and a cooling fan motor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven, and more particularly, to a cooking oven that senses a cooking progress of a food through a sensor and adjusts a remaining cooking time according to the sensed cooking progress. TECHNICAL FIELD The present invention relates to a cooking control method for a microwave oven in which an object is cooked optimally.

[0002]

2. Description of the Related Art Generally, a microwave oven uses a principle in which microwaves are applied to a food to heat the food by frictional heat generated when molecules constituting the food are rubbed. It was done.

Such a cooking control method using a weight sensor of a usual microwave oven will be described with reference to FIG.
When the user selects a cooking course (for example, automatic cooking thawing cooking) through a key input unit (not shown) and inputs a start of cooking, the key input unit outputs a corresponding key signal to the control unit 15, and the weight sensor. 8 senses the weight of the food 1 and outputs a corresponding sensing signal to the controller 15.

The control unit 15 calculates a cooking time according to the weight sensed through the weight sensor 8, and controls the turntable 2, the magnetron 6 and the cooling fan 7 according to the key signal. To the turntable motor 4, the magnetron 6, and the cooling fan motor 11, respectively.

As a result, the turntable motor 4 rotates the turntable 2, the magnetron 6 generates microwaves, and the cooling fan motor 11 rotates the cooling fan 7.

When the turntable 2 is rotated, the food 1 is rotated, and when the cooling fan 7 is rotated, the magnetron 6 is cooled, and the microwaves are introduced into the cooking chamber 3 through the waveguide 5. The food 1 rotated by being radiated is cooked by heating.

Further, the control unit 15 starts counting the time together with the driving of the magnetron 6, and stops the turntable 2, the magnetron 6 and the cooling fan 7 when the counted time passes the calculated cooking time. A control signal for causing the motor to be driven is output to the turntable motor 4, the magnetron 6, and the cooling fan motor 11, respectively.

Accordingly, the turntable motor 4 is
The turntable 2 is stopped, the cooling fan motor 11 stops the cooling fan 7, and the magnetron 6 does not generate microwaves, so that the entire cooking operation is completed.

By the way, the cooking control method using the weight sensor of the usual microwave oven as described above, the cooking is performed irrespective of the state of the food (for example, when the food is frozen or not frozen). During the cooking time calculated according to the weight of the food, the food is heated and cooked, so that there is a problem that the food is not fully cooked or overcooked.

On the other hand, a cooking control method using a normal microwave oven weight sensor has been described above. As another example, a cooking control method using a normal microwave oven gas sensor will be described with reference to FIG. .

When the user inputs a start of cooking after selecting a cooking course (for example, grilling for automatic cooking) through the key input unit, the key input unit outputs a corresponding key signal to the control unit 15.

The control unit 15 starts counting time and sends a control signal for driving the turntable 2, the magnetron 6, and the cooling fan 7 in accordance with the key signal to the turntable motor 4, the magnetron 6, and the cooling fan 7. Output to the fan motor 11 respectively.

As a result, the turntable motor 4 rotates the turntable 2, the magnetron 6 generates microwaves, and the cooling fan motor 11 rotates the cooling fan 7.

When the turntable 2 is rotated, the food 1 is rotated, and when the cooling fan 7 is rotated, the magnetron 6 is cooled, and the microwave is passed through the waveguide 5 into the cooking chamber 3. The food 1 rotated by being radiated is cooked by heating.

At this time, when the cooked food 1 is cooked by heating, a gas sensor 10 is generated and the amount of gas discharged through the exhaust port 9 is sensed, and a corresponding sensing signal is output to the control unit 15 to control. The unit 15 calculates a reference gas amount (for example, 75% of the initial gas amount) according to the initial gas amount detected through the gas sensor 10.

The controller 15 determines whether the gas amount detected through the gas sensor 10 has reached the reference gas amount. If it is determined that the gas amount has reached the reference gas amount, the counted time is shown in Table 1 below. It is determined whether the maximum reference time (670 seconds) of the cooking course count and the maximum reference time data along the cooking course has elapsed.

Further, when it is determined that the counted time does not exceed the maximum reference time, the control unit 15 sets the counted time as an initial cooking time and calculates a remaining cooking time (initial cooking time × table 1 in Table 1 below). While calculating the cooking course count (0.4), if it is determined that the counted time has exceeded the maximum reference time, the remaining cooking time is calculated using the maximum reference time as the initial cooking time.

When the calculated remaining cooking time elapses, the control unit 15 sends a control signal for stopping the turntable 2, the magnetron 6 and the cooling fan 7 to the turntable motor 4, the magnetron 6 and Output to the cooling fan motor 11 respectively.

As a result, the turntable motor 4
The turntable 2 is stopped, the cooling fan motor 11 stops the cooling fan 7, and the magnetron 6 does not generate microwaves, so that the entire cooking operation is completed.

[0020]

[Table 1]

In the above-described cooking control method using a gas sensor of a normal microwave oven, an initial cooking time is calculated only by a preset maximum reference time, and the initial cooking time is calculated in accordance with the calculated initial cooking time. When the gas sensor senses the gas amount smaller or larger than the actual amount by heating the cooked food during the remaining cooking time, there is a problem that the cooked food is immature or overcooked.

On the other hand, the automatic cooking control method using the weight sensor or the gas sensor of the ordinary microwave oven has been described above, but as another example, the ordinary manual cooking control method of the microwave oven will be described with reference to FIG. explain.

A cooking course (for example, manual cooking in which a user inputs a cooking temperature and a cooking time) through a key input unit.
When the start of cooking is input after selecting, the key input unit outputs a corresponding key signal to the control unit 15.

The control unit 15 controls the turntable 2, the magnetron 6, and the cooling fan 7 according to the key signal.
Control signal for driving the turntable motor 4
To the magnetron 6 and the cooling fan motor 11.

As a result, the turntable motor 4 rotates the turntable 2, the magnetron 6 generates microwaves, and the cooling fan motor 11 rotates the cooling fan 7.

When the turntable 2 is rotated, the food 1 is rotated, and when the cooling fan 7 is rotated, the magnetron 6 is cooled, and the microwave is passed through the waveguide 5 into the cooking chamber 3. The food 1 rotated by being radiated is cooked by heating.

Further, the control section 15 starts counting the time together with the driving of the magnetron 6 and stops the turntable 2, the magnetron 6 and the cooling fan 7 when the counted time exceeds the cooking time input by the user. A control signal for causing the turntable motor 4, the magnetron 6, and the cooling fan motor 11 to output a control signal for notifying the end of cooking to a buzzer (not shown) and a display unit (not shown), respectively. .

As a result, the turntable motor 4 and the cooling fan motor 11 are stopped, the magnetron 6 does not generate microwaves, the buzzer generates a cooking end sound, and the display unit displays the cooking end. The overall cooking operation ends.

In the above-mentioned conventional manual cooking control method for a microwave oven, when a user inputs a cooking temperature or a cooking time excessively incorrectly, the food is excessively heated and the food is baked. There was a problem.

[0030]

And 4.

In FIG. 2, when the user inputs a cooking course and a start of cooking of the food, the key input section 20
A corresponding electric key signal is output, and the temperature sensor 22 senses the temperature in the cooking chamber (3 in FIG. 1) and outputs a corresponding sensing signal. It is installed.

Further, the control unit 30 controls the turntable motor (see 4 in FIG. 1), the magnetron (see 6 in FIG. 1) and the cooling fan motor (see FIG. 1) in accordance with the key signal input from the key input unit 20. 11) is transmitted to the turntable motor drive unit 40, the magnetron drive unit 42, and the cooling fan motor drive unit 44.
And output respectively.

Further, the control unit 30 determines whether the temperature sensed through the temperature sensor 22 has reached the reference temperature, and when it is determined that the temperature has reached the reference temperature, counts the time. When it is determined that the cooking time has elapsed and the remaining cooking time has elapsed, a control signal for stopping the turntable motor, the magnetron, and the cooling fan motor is transmitted to the turntable motor driving unit 40.
To the magnetron drive unit 42 and the cooling fan motor drive unit 44.

Further, the turntable motor driving section 40

Further, the cooling fan motor driving unit 44
The cooling fan motor is driven or stopped by the control signal of the control unit 30.

Hereinafter, a method for controlling cooking of a microwave oven according to the first embodiment of the present invention through the microwave oven configured as described above will be described in detail with reference to FIGS.

First, after the user selects a cooking course (for example, grilling for automatic cooking) through the key input unit 20 and inputs a start of cooking, the key input unit 20 outputs a corresponding key signal to the control unit 30 ( S10).

The controller 30 receives the key signal and determines whether or not cooking has started. If it is determined that cooking has not started, the controller 30 repeatedly determines whether or not cooking has started. If it is determined that there is, a control signal for driving the turntable motor, the magnetron, and the cooling fan motor is output to the turntable motor drive unit 40, the magnetron drive unit 42, and the cooling fan motor drive unit 44 (S20).

Thus, the turntable motor drive section 40 drives the turntable motor, the magnetron drive section 42 drives the magnetron, and the cooling fan motor drive section 44 drives the cooling fan motor.

When the turntable motor is driven, the turntable is rotated to rotate the food, and when the cooling fan motor is driven, the cooling fan is rotated to cool the magnetron, and the magnetron is driven. As a result, microwaves are generated and the rotated food is cooked (S30).

At this time, the temperature sensor 22 senses the temperature in the cooking chamber and outputs a corresponding sensing signal to the controller 30 (S40), and the controller 30 receives the sensing signal and detects the sensed temperature. It is determined whether or not the reference temperature (specifically, the temperature set along the cooking course) has been reached (S5).
0) If it is determined that the reference temperature has not been reached, while it is repeatedly determined whether the temperature sensed by cooking the food has reached the reference temperature, if it is determined that the reference temperature has been reached, Time counting is started (S60).

Further, the control unit 30 determines whether the counted time has passed the remaining cooking time (specifically, the time preset along the cooking course), and determines whether the remaining cooking time has elapsed. When it is determined that the remaining cooking time has elapsed, while it is determined that the remaining cooking time has elapsed, while it is repeatedly determined whether the counted time has elapsed the remaining cooking time,
A control signal for stopping the turntable motor, the magnetron, and the cooling fan motor is output to the turntable motor drive unit 40, the magnetron drive unit 42, and the cooling fan motor drive unit 44 (S70).

Thus, the turntable motor drive section 40 stops the turntable motor, the magnetron drive section 42 stops the magnetron, and the cooling fan motor drive section 44 stops the cooling fan motor.

When the turntable motor is stopped, the turntable is not rotated. When the cooling fan motor is stopped, the cooling fan is not rotated. When the magnetron is stopped, no microwave is generated. Therefore, cooking of the food is stopped (S
80).

Therefore, the cooking control method of the microwave oven according to the first embodiment of the present invention counts the time when the temperature sensed through the temperature sensor reaches the preset reference temperature along the cooking course selected by the user. Cooking the cooking while the counted time passes the preset remaining cooking time along the cooking course selected by the user, thereby preventing the cooking of the cooking from being immature or overcooking; This has the effect of allowing you to cook things optimally.

Next, a microwave cooking control method according to a second embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 4 is a schematic block diagram of a microwave oven for performing a microwave cooking control method according to the second embodiment of the present invention.
2, a weight sensor 54, a control unit 60, a turntable motor drive unit 70, a magnetron drive unit 72, and a cooling fan motor drive unit 74.

In FIG. 4, the same parts as those in the configuration of the microwave oven according to the first embodiment of the present invention are given the same names and reference numerals, and the detailed description thereof is omitted.

Referring to FIG. 4, a gas sensor 52 detects gas generated during cooking of a food and outputs a corresponding detection signal, and a weight sensor 54 detects the weight of the food and detects a corresponding detection signal. Is output.

Further, the control unit 60 sends a control signal for driving the turntable motor, the magnetron and the cooling fan motor in accordance with the key signal input from the key input unit 50, to the turntable motor drive unit 70 and the magnetron drive unit. The time is output to the cooling fan motor drive unit 72 and the cooling fan motor drive unit 74, and the time is counted.

Further, the control unit 60 receives the sensing signal from the weight sensor 54, calculates the number of cooking courses along the cooking course in Table 2 and calculates the maximum reference time of the minimum and maximum reference time data. Is input to calculate the reference gas amount.

Further, the control unit 60 determines whether or not the gas amount sensed through the gas sensor 52 has reached the reference gas amount. When it is determined that the gas amount has reached the reference gas amount, the counted time is shown in Table 2 below. It is determined whether or not the minimum reference time has elapsed.If it is determined that the minimum reference time has not elapsed, the time counted after cooking the food to the minimum reference time is set as the initial cooking time, and the remaining cooking time is set as the initial cooking time. On the other hand, if it is determined that the minimum reference time has elapsed, it is determined whether the counted time is less than the maximum reference time.

Further, if the counted time is less than the maximum reference time, the controller 60 calculates the remaining cooking time using the counted time as the initial cooking time, while the counted time is less than the maximum reference time. Otherwise, the remaining cooking time is calculated using the maximum reference time as the initial cooking time, and when the counted time passes the calculated remaining cooking time, the control signal for stopping the turntable motor, the magnetron, and the cooling fan motor is turned off. Table motor drive unit 70
Are output to the magnetron drive unit 72 and the cooling fan motor drive unit 74, respectively.

[0061]

[Table 2] In Table 2, the weight at the maximum reference time is the weight of the food and the unit is (g).

FIG. 5 is a diagram showing a gas amount with respect to a cooking time for explaining a method of controlling cooking of a microwave oven according to the second embodiment of the present invention. As can be seen from FIG. The cooking time until the amount reaches the reference gas amount (for example, 75% of the initial gas amount) is referred to as the initial cooking time, and the cooking time after the reference gas amount has reached the reference gas amount is referred to as the remaining cooking time.

Hereinafter, a method for controlling cooking of a microwave oven according to the second embodiment of the present invention through the microwave oven configured as described above will be described in detail with reference to FIGS.

First, when the user inputs a start of cooking after selecting a cooking course (for example, baking for automatic cooking) through the key input unit 50, the key input unit 50 outputs a corresponding key signal to the control unit 60 ( S110).

The controller 60 receives the key signal, determines whether or not the cooking is to be started. If it is determined that the cooking is not to be started, the controller 60 repeatedly determines whether or not the cooking is started. If it is determined that there is, a control signal for driving the turntable motor, the magnetron, and the cooling fan motor is output to the turntable motor driving unit 70, the magnetron driving unit 72, and the cooling fan motor driving unit 74 (S115).

Thus, the turntable motor drive unit 70 drives the turntable motor, the magnetron drive unit 72 drives the magnetron, and the cooling fan motor drive unit 74 drives the cooling fan motor.

When the turntable motor is driven, the turntable is rotated to rotate the food, and when the cooling fan motor is driven, the cooling fan is rotated to cool the magnetron, and the magnetron is driven. As a result, microwaves are generated and the food to be rotated is heated and cooked (S120).

Further, the control unit 60 starts counting the time when the magnetron is driven (S125), and the weight sensor 54 detects the weight of the food and outputs a corresponding sensing signal to the control unit 60 (S125). S130), control unit 60
Calculates the maximum reference time ((0.3 × weight + 150) seconds) in Table 2 by receiving the sensing signal (S13).
5).

At this time, the gas sensor 52 detects the gas generated by heating the cooked food, and outputs a corresponding sensing signal to the controller 60 (S140), and the controller 60 outputs the sensing signal. The input and reference gas amount is calculated as shown in FIG. 5 (75% of the initial gas amount) (S14).
5) It is determined whether the gas amount detected through the gas sensor 52 has reached the reference gas amount (S150).

The control unit 60 determines whether the step (S15)
If it is determined that the gas amount sensed through the gas sensor 52 is not equal to the reference gas amount as a result of the determination 0), it is determined whether the gas amount sensed through the gas sensor 52 is equal to the reference gas amount. Is repeated, if it is determined that the reference gas amount has been reached, it is determined whether the counted time has passed the minimum reference time (70 seconds) in Table 2 (S155).

The control unit 60 determines whether the step (S15)
If it is determined that the counted time does not exceed the minimum reference time in step 5), the cooked food is cooked to the minimum reference time (S160), and the counted time is set as the initial cooking time (S160). (S170) The remaining cooking time (initial cooking time x cooking course count (0.4) shown in Table 2) is calculated (S180).

Further, when it is determined that the counted time has passed the minimum reference time as a result of the determination in the step (S155), the control unit 60 determines whether the counted time is less than the maximum reference time. If it is determined (S165) that the time is less than the maximum reference time, the counted time is set as the initial cooking time (S170), and the remaining cooking time is calculated (S180).

The control unit 60 determines whether the step (S16)
If it is determined that the counted time is not less than the maximum reference time as a result of 5), the maximum reference time is set as the initial cooking time (S175), and the remaining cooking time is calculated (S18).
0).

Further, the control unit 60 determines whether the counted time has passed the calculated remaining cooking time. If it is determined that the remaining cooking time has not elapsed, the control unit 60 calculates the counted time. While it is repeatedly determined whether the remaining cooking time has elapsed, if it is determined that the remaining cooking time has elapsed, a control signal for stopping the turntable motor, the magnetron, and the cooling fan motor is turned on. Output to the unit 70, the magnetron driving unit 72, and the cooling fan motor driving unit 74 (S1).
85).

As a result, the turntable motor driving section 70 stops the turntable motor, the magnetron driving section 72 stops the magnetron, and the cooling fan motor driving section 74 stops the cooling fan motor.

When the turntable motor is stopped, the turntable is not rotated. When the cooling fan motor is stopped, the cooling fan is not rotated. When the magnetron is stopped, no microwave is generated. Therefore, cooking of the food is stopped (S1).
90).

Therefore, the cooking control method for a microwave oven according to the second embodiment of the present invention calculates the initial cooking time using the gas sensor and the weight sensor, calculates the remaining cooking time, and calculates the remaining cooking time during the calculated remaining cooking time. By cooking the food by heating, it is possible to prevent the cooking of the food from being unripe or overcooked, and to have an effect of optimally cooking the food.

Next, a cooking control method for a microwave oven according to Embodiment 3 of the present invention will be described in detail with reference to the attached drawings.

FIG. 7 is a schematic block diagram of a microwave oven for performing a microwave cooking control method according to the third embodiment of the present invention, in which a key input unit 80 and a gas sensor 8 are provided.
2, control unit 90, turntable motor drive unit 100,
Magnetron drive unit 102, cooling fan motor drive unit 1
04, a buzzer 106, and a display unit 108.

In FIG. 7, the same parts as those in the configuration of the microwave oven according to the second embodiment of the present invention are denoted by the same names and reference numerals, and the detailed description thereof will be omitted.

In FIG. 7, the control section 90 sends a control signal for driving the turntable motor, the magnetron and the cooling fan motor according to the key signal input from the key input section 80 to the turntable motor drive section 100.
Are output to the magnetron drive unit 102 and the cooling fan motor drive unit 104, respectively.

Further, the control unit 90 determines whether the gas amount detected through the gas sensor 82 has reached the reference gas amount, and when it is determined that the gas amount has reached the reference gas amount, counts the time. It is determined whether the remaining cooking time has elapsed. If it is determined that the remaining cooking time has elapsed, a control signal for stopping the turntable motor, the magnetron, and the cooling fan motor is transmitted to the turntable motor drive unit 100 and the magnetron drive. In addition to outputting to control section 102 and cooling fan motor driving section 104, a control signal for notifying the end of cooking is output to buzzer 106 and display section 108, respectively.

Further, the buzzer 106 generates a cooking end sound according to the control signal of the control section 90, and the display section 108 displays the cooking end according to the control signal of the control section 90.

Hereinafter, a method of controlling cooking of a microwave oven according to the third embodiment of the present invention through the microwave oven configured as described above will be described in detail with reference to FIGS.

First, when the user selects a cooking course (for example, manual cooking for inputting a cooking temperature and a cooking time) through the key input unit 80 and then inputs a cooking start,
The key input unit 80 transmits a corresponding key signal to the control unit 90.
(S210).

The controller 90 receives the key signal and determines whether or not the cooking has started. If it is determined that the cooking has not started, the controller 90 repeatedly determines whether or not the cooking has started. If it is determined that there is, a control signal for driving the turntable motor, the magnetron and the cooling fan motor is transmitted to the turntable motor drive unit 100.
Is output to the magnetron driving unit 102 and the cooling fan motor driving unit 104 (S220).

As a result, the turntable motor drive unit 100 drives the turntable motor, the magnetron drive unit 102 drives the magnetron, and the cooling fan motor drive unit 104 drives the cooling fan motor.

When the turntable motor is driven, the turntable is rotated to rotate the cooked food. When the cooling fan motor is driven, the cooling fan is rotated to cool the magnetron, and the magnetron is driven. As a result, microwaves are generated to rotate and cook the cooked food (S230).

At this time, the gas sensor 82 detects the gas generated by heating the cooked food, and outputs a corresponding sensing signal to the controller 90 (S240), and the controller 90 outputs the sensing signal. It is determined whether the input and sensed gas amount has reached a reference gas amount (specifically, a preset gas amount corresponding to the time when the food is boiled) (S25).
0) When it is determined that the gas amount has not reached the reference gas amount, while it is repeatedly determined whether the gas amount sensed through the gas sensor 82 has reached the reference gas amount, it is determined that the gas amount has reached the reference gas amount. , Start counting time (S26)
0).

The control unit 90 determines whether the counted time has passed the remaining cooking time (specifically, a preset time at which cooking is completed after the boiling of the food is started) and the remaining cooking time is determined. When it is determined that the time has not elapsed, the determination whether the counted time has elapsed the remaining cooking time is repeated, while when it is determined that the remaining cooking time has elapsed, the turntable motor, the magnetron, and A control signal for stopping the cooling fan motor is output to the turntable motor driving unit 100, the magnetron driving unit 102, and the cooling fan motor driving unit 104, respectively (S27).
0).

Thus, the turntable motor driving section 1
00 stops the turntable motor, the magnetron driving unit 102 stops the magnetron, and the cooling fan motor driving unit 104 stops the cooling fan motor.

When the turntable motor is stopped, the turntable is not rotated. When the cooling fan motor is stopped, the cooling fan is not rotated. When the magnetron is stopped, no microwave is generated. Therefore, cooking of the food is stopped (S
280).

Further, the control unit 90 outputs a control signal for notifying the end of cooking to the buzzer 106 and the display unit 108, whereby the buzzer 106 generates a cooking end sound and the display unit 108 After the completion of cooking is displayed, the entire cooking operation is completed (S290).

Accordingly, the cooking control method of the microwave oven according to the third embodiment of the present invention counts the time when the gas amount sensed through the gas sensor at the time of manual cooking reaches the preset reference gas amount, and counts the counted time. When cooking time or cooking time is erroneously input by the user by stopping cooking of the food when the preset remaining cooking time has elapsed, excessive cooking of the food is prevented and There is an effect that can be optimally cooked.
