4 is a view for explaining a method of operating an electric rice cooker according to an embodiment of the present invention.

The controller 170 may determine the type of food contained in the cooking container 270 (S410).

Specifically, the controller 170 may acquire information that the food contained in the cooking container 270 is the first food among the plurality of foods based on the cooking mode of the electric rice cooker.

For example, the cooking mode of the electric rice cooker may include a white rice cooking mode, a brown rice cooking mode, a mixed grain cooking mode, and the like.

In addition, when cooking is performed by the brown rice cooking mode, the controller 170 may obtain information that the food contained in the cooking container 270 is brown rice among a plurality of foods (white rice, brown rice, and mixed grains).

Meanwhile, the controller 170 may determine the weight of the container containing the first food ( S420 ).

Specifically, the sensing unit 110 may obtain data on the weight of the cooking vessel, and the control unit 70 information on the weight of the cooking vessel 270 based on the data on the weight of the cooking vessel 270 . can be obtained.

Meanwhile, the user may open the main body cover 220 and put a portion of the first food contained in the cooking container 270 into the bowl, and accordingly, the first food contained in the cooking container 270 may be removed.

Meanwhile, when the first food is taken out, the controller 170 may display the amount of heat of the first food taken out (S430).

This will be described in detail with reference to FIG. 5 .

5 is a view showing information displayed on the display unit when the weight of the cooking vessel is reduced by one time according to an embodiment of the present invention.

When the weight of the cooking container 270 decreases as the first food is removed, the controller 170 adjusts the amount of calories of the first food removed based on the reduced weight of the cooking container and the amount of heat per unit weight of the first food. information can be obtained.

Specifically, when the weight of the cooking vessel 270 decreases as the first food is removed, the controller 170 may determine the reduced weight of the cooking vessel.

Here, the reduced weight of the cooking container may coincide with the weight of the reduced first food. Accordingly, the controller 170 may acquire information on the weight of the first food that has been removed based on the reduced weight of the cooking container.

For example, as the user puts a portion of the brown rice contained in the cooking container 270 into the bowl, the brown rice in the cooking container 270 may be reduced. In addition, the combined weight of the cooking container 270 and the brown rice before the brown rice is removed may be 1000 grams, and the combined weight of the cooking container 270 and the brown rice after the brown rice is removed may be 982 grams.

In this case, the controller 170 may determine that the weight of the removed brown rice is 18 grams.

Meanwhile, the controller 170 may acquire information on the amount of calories of the first food that has been removed based on the reduced weight of the cooking container and the amount of heat per unit weight of the first food.

For example, when the calorie per gram of brown rice is 1.8 Kcal and the weight of the reduced cooking container (that is, the weight of a portion of the removed brown rice) is 18 grams, the controller 170 determines that the amount of calories of the reduced brown rice is 32.4 Information called Kcal can be obtained.

In this case, the calorie per unit weight of the first food may be stored in the storage unit 140 .

Meanwhile, when information on the amount of heat of the first food that has been taken out is obtained, the controller 170 may control the display 130 to display the information 560 about the amount of heat of the first food that has been taken out.

In this case, the controller 170 may display the information 540 on the weight of the first food that has been taken out together.

On the other hand, when a plurality of foods can be cooked in the cooking container 270 , the controller 170 controls the calorie per unit weight of the first food contained in the first cooking container 270 among the plurality of foods and the reduced weight of the cooking container. Based on the , information 540 on the amount of calories of the first food that has been removed may be displayed.

Specifically, the storage unit 140 may store information on the amount of calories per unit weight of a plurality of foods.

For example, the storage unit 140 may store information on calories per unit weight of white rice, information on calories per unit weight of brown rice, and information on calories per unit weight of mixed grain rice.

Meanwhile, the controller 170 may determine the type of food contained in the cooking container 270 as described in S410 .

For example, it may be determined that the food contained in the cooking container 270 is brown rice among a plurality of foods.

In addition, the controller 170 may display information on the heat of the reduced brown rice based on the calorie per unit weight of the brown rice contained in the first cooking container 270 among the plurality of foods and the reduced weight of the cooking container. .

In this case, the controller 170 may display the information 540 on the amount of calories of the first food that has been removed together with the information 510 on the type of the first food.

As such, in the present invention, when the user cooks rice, the amount of heat corresponding to the amount of spread rice can be displayed directly in the rice cooker.

Accordingly, it is possible to reduce the hassle of moving food to a separate measuring device for calorie counting, and there is an advantage that rice can be added or reduced on the spot according to the measurement result.

In addition, various foods can be cooked in the electric rice cooker. In this case, the electric rice cooker can improve user convenience by determining what kind of food is cooked without a separate input. In addition, there is an advantage in that the calorific value of food can be accurately provided by applying different calorific values per unit weight according to the type of food.

Meanwhile, in the above-described embodiment, it has been described that the calories of the first food are calculated based on the weight of the first food and the amount of calories of the first food, but it is not limited thereto.

In one embodiment, the controller 170 may display information on the amount of calories of the first food that has been removed based on the information on the calorific value per unit weight of the first food, the reduced weight of the cooking container, and the moisture content in the first food. can

Specifically, the controller 170 may acquire information on the moisture content in the first food.

More specifically, the moisture sensor 116 may acquire data on moisture in the first food, and the controller 170 acquires information on the moisture content of the first food based on the data on moisture in the first food. can do.

Meanwhile, heat loss per unit weight of the first food may vary according to the moisture content of the first food.

For example, the calorie per unit weight of the first food may be higher when the moisture content of the first food is 55% than when the moisture content is 65%.

In this case, the control unit 170 may correct the amount of heat of the first food that has been taken away based on the moisture content of the first food.

Specifically, in the preceding embodiment, it has been described that the amount of calories of the first food removed is calculated based on the reduced weight of the cooking container (ie, the weight of the first food removed) and the amount of calories per unit weight of the first food. The calorific value of the first food calculated here may be calculated on the assumption that the moisture content of the first food is a preset content.

In this case, the controller 170 may correct the calculated calorie amount of the first food based on the preset content and the actual moisture content of the first food, and display the corrected calorie content.

In this case, the controller 170 may display the information 530 on the moisture content of the first food together.

Meanwhile, in the above-described embodiment, it has been described that the calorific value of the first food removed based on the moisture content of the first food is corrected, but the present invention is not limited thereto.

Specifically, the control unit 170 receives information on the amount of calories of the first food removed based on the information on the amount of calories per unit weight of the first food, the reduced weight of the cooking container, and the time the first food is stored in the electric rice cooker. can be displayed.

Specifically, the control unit 170 may include a timer, and the control unit 170 may obtain information about the time the first food is stored in the electric rice cooker. In this case, the starting point of the time the first food is stored in the electric rice cooker may be the time when the cooking of the first food is completed.

Meanwhile, the moisture content of the first food may vary depending on the time the first food is stored in the electric rice cooker.

For example, as the first food is stored for a long time in the electric rice cooker, moisture is released from the first food and the moisture content of the first food may be lowered.

In this case, the controller 170 may correct the amount of calories of the first food taken away based on the time the first food is stored in the electric rice cooker.

Specifically, in the preceding embodiment, it has been described that the amount of calories of the first food removed is calculated based on the reduced weight of the cooking container (ie, the weight of the first food removed) and the amount of calories per unit weight of the first food. The calorific value of the first food calculated here may be calculated on the assumption that cooking is completed.

In this case, the controller 170 may correct the calculated calorific value of the first food based on the calculated calorific value of the first food and the time the first food is stored in the electric rice cooker, and may display the corrected calorific value.

In this case, the controller 170 may display the information 520 on the time the first food is stored in the electric rice cooker together.

As described above, the present invention has the advantage of being able to more accurately provide the calories of food by measuring or predicting the moisture content of the food and then performing the correction.

Referring back to FIG. 4 , if the weight of the cooking container is reduced a plurality of times as the first food is unloaded a plurality of times, the controller 170 may display the accumulated calorie of a portion of the first food that has been taken out a plurality of times ( S440 ). ).

This will be described in detail with reference to FIGS. 5 and 6 .

5 is a view showing information displayed on the display unit when the weight of the cooking vessel is reduced by one time according to an embodiment of the present invention.

6 is a view showing information displayed on the display unit when the weight of the cooking vessel is reduced a plurality of times according to an embodiment of the present invention.

The control unit 170 may display at least one of information on the accumulated weight of the first food that has been taken out and information about the amount of accumulated calories of the first food that has been taken out.

Here, the accumulated weight may be the sum of all the weights of the first food that have been removed so far.

The cumulative calorific value may be the sum of all the calorific values of the first food that have been removed so far.

As shown in FIG. 5 , when the first food is taken out once, the weight 540 of the first food dispensed once may be equal to the accumulated weight 550 of the first food dispensed so far.

Also, as illustrated in FIG. 5 , when the first food is taken out once, the amount of heat 560 of the first food that is taken out once and the accumulated heat amount 570 of the first food that has been taken out so far may be the same as shown in FIG. 5 .

On the other hand, if the weight of the cooking container is reduced a plurality of times as the first food is unloaded a plurality of times, the controller 170 may display the accumulated calorie of the first food taken out a plurality of times.

Specifically, if the weight of the cooking container decreases a plurality of times as the first food is unloaded a plurality of times, the control unit 170 calculates the accumulated weight of the first food that has been removed multiple times by adding up the weight of the cooking container that has been reduced a plurality of times. information can be obtained.

In addition, when information on the accumulated weight of the first food that has been unloaded a plurality of times is obtained, the controller 170 controls the amount of calories to be taken out a plurality of times based on the amount of calories per unit weight of the first food and the accumulated weight of the first food that has been unloaded a plurality of times. Information on the accumulated calorie of the first food may be acquired.

Meanwhile, the control unit 170 may display information 640 on the accumulated calories of the first food that has been taken out a plurality of times. In this case, the controller 170 may display the information 620 on the accumulated weight of the first food taken out a plurality of times together.

Also, the controller 170 may display information 630 on the calorific value of the first food that was most recently removed. In this case, the controller 170 may display the information 610 on the weight of the first food most recently taken out together.

For example, if the brown rice is 18 grams in the first, 52 grams in the second, 14 grams in the third, and 36 grams in the fourth, the controller 170 determines that the accumulated weight of the brown rice removed four times is 120 grams. It is possible to display the information 620 and the accumulated calorie amount of brown rice that is served 4 times is 216 Kcal.

In addition, the control unit 170 determines that the weight of the most recently removed (that is, removed in the 4th time) brown rice is 36 grams and that the caloric value of the most recently removed (ie, removed in the fourth) brown rice is 64.8 grams. information can be displayed.

It is difficult to put the rice in a bowl by adjusting the amount at once, so the operation of unpacking the rice is repeated several times.

In this case, the present invention can facilitate the user to control the amount of rice by providing the accumulated calorie of food.

Returning to FIG. 4 again, the controller 170 may output an alarm when the accumulated calorie is greater than a preset value.

This will be described with reference to FIG. 6 .

The controller 170 may output an alarm when the amount of accumulated heat is greater than a preset value.

For example, when the preset value is 200 Kcal and the accumulated calorie is 216 Kcal, the controller 170 may output an alarm.

Here, the preset value may be input by the user through the input unit 120 .

In this case, the control unit 170 may control the sound output unit 160 to output an alarm sound.

As another embodiment, the controller 170 may control the display 130 to display the alert notification 650 .

Meanwhile, the control unit 170 may receive an input for resetting the calculation of the accumulated heat quantity through the input unit 120 .

In this case, the controller 170 resets the accumulated weight and the accumulated calorie of the first food to 0, and when the weight of the cooking container decreases as the first food is removed, the accumulated weight and the accumulated calorie of the first food are again reset. can be calculated.

As described above, the present invention has the advantage of being able to easily inform that the amount of rice exceeds the reference value.

Also, if you cook rice for family members, you will be eating several bowls of rice. In this case, by resetting the accumulated heat amount, there is an advantage in that the accumulated heat amount can be measured for each bowl.

Returning to FIG. 4 again, the controller 170 may transmit cooking information to an external device.

This will be described in detail with reference to FIGS. 7 to 8 .

7 is a diagram illustrating an electric rice cooker communicating with a microwave oven according to an embodiment of the present invention.

8 is a diagram illustrating a display unit of a microwave oven according to an embodiment of the present invention.

The control unit 170 may communicate with an external device through the communication unit 150 .

Here, it is assumed that the electric rice cooker 10 communicates with the microwave oven 20 . However, the present invention is not limited thereto, and the electric rice cooker 10 has a communication unit and can communicate with all external devices capable of cooking food.

Meanwhile, the sensing unit 110 may acquire data on the temperature of the first food, and the controller 170 may acquire information on the temperature of the first food based on the data on the temperature of the first food. .
