For example, while the cooking appliance 100 immediately performs the eating mode (S30), when the user manipulates the operation unit corresponding to the warming eating mode of the input unit 110, the input unit 110 may set the warming eating mode. It is possible to generate a mode change signal to perform. Alternatively, while the cooking appliance 100 performs the warm eating mode (S60), when the user operates the operation unit corresponding to the immediate eating mode of the input unit 110, the input unit 110 immediately performs the eating mode. It is possible to generate a mode change signal for In this case, the mode change signal for performing the warming and eating mode and the mode change signal for performing the immediate eating mode may be one signal that is the same or different from each other.

The control unit 130 may determine whether a mode change signal is received while performing the immediate eating mode (S30). If a mode change signal is received before performing the moxibustion step (S35) of the first mode, that is, while performing the serving determination step (S31) or the boiling step (S33), the controller 130 It is possible to perform the moxibustion step (S65) of the mode. The control unit 130 may control the display unit 120 and/or the notification unit 170 to notify the user visually and/or aurally that the user has changed from the immediate eating mode (S30) to the warm eating mode (S60).

If a mode change signal is not received while performing the serving determination step S31 or the boiling step S33, the controller 130 may perform the steaming step S35 of the first moxibustion mode. In one embodiment, when a mode change signal is not received while performing the serving determination step S31 or the boiling step S33, and a mode change signal is received while performing the moxibustion step S35 of the first moxibustion mode, The controller 130 may control the display unit 120 and/or the notification unit 170 to visually and/or audibly notify that mode change is impossible.

If a mode change signal is received before performing the second mode moxibustion step (S65), that is, while performing the serving determination step (S61) or the boiling step (S63), the controller 130 It is possible to perform the moxibustion step (S35) of the mode. The control unit 130 may control the display unit 120 and/or the notification unit 170 to visually and/or audibly notify the user that the change from the warming and eating mode (S60) to the immediate eating mode (S30).

When a mode change signal is not received while performing the serving determination step S61 or the boiling step S63, the controller 130 may perform the steaming step S65 of the second moxibustion mode. In one embodiment, if a mode change signal is not received while performing the serving determination step S61 or the boiling step S63, and a mode change signal is received while performing the moxibustion step S65 of the second moxibustion mode, The controller 130 may control the display unit 120 or the notification unit 170 to visually or aurally notify that mode change is impossible.

The cooking apparatus 100 according to the present disclosure may provide a plurality of eating modes so that the user can select whether to eat cooked rice immediately or after keeping warm for a predetermined time. The user may change the eating mode even while the cooking device 100 is cooking, thereby improving the user's satisfaction with the quality of rice.

Referring back to FIGS. 1 and 2, the control unit 130 may detect food (eg, rice) inside the inner pot (S40) immediately after performing the eating mode (S30) is completed. In the food detection step (S40), the control unit 130 may control the sensing unit 180 to detect the food remaining inside the inner pot, and receive the detection result from the sensing unit 180, You can determine whether this is empty or not.

In one embodiment, the step of detecting food inside the inner pot (S40) may be performed immediately after the execution of the eating mode (S30) is completed and a specific time elapses. The specific time may be stored in the storage unit 140, and the control unit 130 may perform a step S40 of determining whether rice remains in the inner pot based on the specific time stored in the storage unit 140. I can.

When food remains inside the inner pot, the controller 130 may perform a first warming step (S50) of keeping the remaining food warm for a specific time. In one embodiment, the rice cooked by immediately performing the eating mode (S30) may have a higher moisture content than the cooked rice by performing the warm eating mode (S60). Accordingly, in performing the thermal insulation operation to store the remaining rice, the maximum thermal insulation time for performing the thermal insulation operation may be determined. The controller 130 may perform the first warming step (S50) for a time less than the maximum warming time (eg, a first time) based on information on the maximum warming time stored in the storage unit. In the first warming step S50, the controller 130 may control the heating unit 150 and the valve 160 so that the cooked food is maintained at an appropriate temperature. When the first time elapses, the controller 130 may turn off the operation of the heating unit 150.

When food is not detected inside the inner pot, that is, when the inner pot is empty, the controller 130 may end the operation.

The cooking apparatus 100 according to the present disclosure may provide a plurality of eating modes so that a user can select whether to eat food (eg, rice) that has been cooked immediately or to eat after warming for a predetermined time. Therefore, in one embodiment, according to the user's selection, the cooking appliance 100 immediately cooks rice to have a soft texture in the eating mode, and in the warm eating mode, the rice is cooked so as to suppress the occurrence of off-flavor and whitening. You can cook.

However, when the user immediately selects the eating mode in order to immediately cook the food for eating, but not all of the food is left, the maximum warming time may be designated in order to efficiently process the remaining food. For example, rice for immediate consumption, which is cooked by performing the immediate eating mode, has a higher moisture content than the rice for warming cooked by performing the warming mode, so if it is kept warm for an excessively long time, off-flavor or whitening may occur. I can. Therefore, when the cooking device 100 performs the warming step in order to store the rice for eating as soon as it remains, the heat retention step is performed for a time less than the maximum heat retention time previously stored in the storage unit 140 to prevent off-flavor or whitening. It can suppress the outbreak.

5 is a table showing the degree of an eating mode stored in a storage unit of a cooking appliance according to an exemplary embodiment of the present disclosure, and is a table for explaining an operation of a valve in a steaming step when rice is cooked.

1, 3, 4, and 5, the eating mode information stored in the storage unit 140 is a valve in each of the moxibustion step S35 in the first mode and the moxibustion step S65 in the second mode. 160) may include information on the open point. The controller 130 may control the opening and closing of the valve 160 based on the eating mode information stored in the storage unit 140. In one embodiment, the time from the start point of the moxibustion step S35 in the first mode to the point at which the valve 160 is opened is the time point at which the valve 160 is open from the start point of the moxibustion step S65 in the second mode It can be longer than the time to.

When the boiling step (S33) is completed in the immediate eating mode (S30), the controller 130 may perform the moxibustion step of the first mode (S35). In one embodiment, when the moxibustion step (S35) of the first mode starts, the controller 130 closes the valve 160 during the first section, and after the first section (second section), the valve 160 ) Can be opened. By closing the valve 160 during the first section, the controller 130 may cook moist rice without evaporating the moisture of the cooked rice.

The length of the first section may vary according to the number of servings determined in the serving determination step S31. In one embodiment, as the number of servings increases, the length of the first section, that is, the time the valve 160 is closed may increase. The length of the first section corresponding to the serving number may be further stored in the storage unit 140.

On the other hand, when the boiling step (S63) is completed in the warm eating mode (S60), the controller 130 may perform the moxibustion step of the second mode (S65). In one embodiment, when the second mode of moxibustion step S65 is started, the controller 130 may open the valve 160. By opening the valve 160, the control unit 130 may partially evaporate the moisture of the rice cooked in the boiling step S63. If the rice containing a lot of moisture is continuously heated in the warming step (S69), moisture evaporated from the rice may become excessively condensed in the cooking device 100, and thus off-flavor and whitening may occur. Therefore, in the steaming step (S65) of the second mode, the valve 160 is opened earlier than in the steaming step (S35) of the first mode in order to evaporate a portion of the moisture of the rice and discharge it to the outside of the cooking device 100. I can.

6 is a table showing the degree of an eating mode stored in a storage unit of a cooking appliance according to an exemplary embodiment of the present disclosure, and is a table for explaining an operation of a heating unit in a steaming step when cooking rice.

1, 3, 4 and 6, the eating mode information stored in the storage unit 140 is a heating unit in the moxibustion step S35 of the first mode and the moxibustion step S65 of the second mode. Information on the heating output of 150 may be included. The controller 130 may control the heating output of the heating unit 150 based on the eating mode information stored in the storage unit 140.

In the immediate eating mode (S30), when the boiling step (S33) is completed, the controller 130 may perform the moxibustion step of the first mode (S35). In an embodiment, when the first mode of steaming step S35 starts, the controller 130 may stop the heating operation by turning off the output of the heating unit 150. By suppressing evaporation of the moisture of the rice cooked in the boiling step (S33), it is possible to improve the taste.

In the warm eating mode (S60), when the boiling step (S63) is completed, the controller 130 may perform the moxibustion step of the second mode (S65). In one embodiment, when the second mode moxibustion step S65 starts, the controller 130 may perform the moxibustion step algorithm. The controller 130 may control the heating unit 150 to output a specific output value according to the steaming step algorithm. At this time, based on the steaming step algorithm, the heating output of the heating unit 150 may be constant while performing the steaming step S65 of the second mode, or may change over time. For example, the heating output of the heating unit 150 may have a value of a first output in a first section and a value of a second output lower than that of the first output in a second section after the first section. The heating output of the heating unit 150 in the steaming step S65 of the second mode may be lower than the heating output of the heating unit 150 in the boiling step S65.

In the steaming step S65 of the second mode, by maintaining the heating output of the heating unit 150 without turning off, some of the moisture of the rice in the inner pot may be evaporated and discharged to the outside of the cooking appliance 100.

In one embodiment, the control unit 130 may provide a notification to the user so that the user can select less than the maximum warming time in the first warming step stored in the storage 140, but the cooking device according to the present disclosure ( 100) is not limited thereto.

The input unit 110 may obtain a setting input of selection of a warming time from a user and may generate a warming time selection signal corresponding to the setting input. For example, the input unit 110 may provide an operation unit such as a button or a touch screen for the user to select the warming time of the first warming step (S50). When the user selects the warming time, the input unit 110 May generate a warming time selection signal corresponding to the selected warming time.

The controller 130 may determine whether a warming time selection signal is received from the input unit 110 (S53). When the warming time selection signal is not received, the controller 130 may perform a step S55_1 notifying that the warming is terminated after the first time. The first time may be less than or equal to the maximum warming time stored in the storage unit 140. In one embodiment, the first time may be the maximum warming time. The control unit 130 may control the display unit 120 and/or the notification unit 170 to notify that warming is ended after the first time period.

The controller 130 may perform the warming step (S57_1) for the first time. In the warming step (S57_1), the controller 130 may control the heating unit 150 and the valve 160 so that the food remaining in the inner pot is maintained at an appropriate temperature.

When the first time has elapsed, the controller may perform a thermal insulation termination notification step (S59_1) informing that thermal insulation has ended. The control unit 130 may control the display unit 120 and/or the notification unit 170 to visually and/or audibly notify the user of the end of warming.

On the other hand, when a warming time selection signal is received from the input unit 110, the control unit 130 may perform a step S55_2 notifying that the warming is terminated after the second time. The second time may be a time corresponding to the received warming time selection signal. In an embodiment, the second time may be shorter than the maximum warming time. The control unit 130 may control the display unit 120 and/or the notification unit 170 to notify that warming is ended after the second time period.

The controller 130 may perform the warming step S57_2 for a second time. In the warming step (S57_2), the controller 130 may control the heating unit 150 and the valve 160 to maintain the rice remaining in the inner pot at an appropriate temperature.

When the second time has elapsed, the controller may perform a thermal insulation termination notification step S59_2 informing that the thermal insulation has ended. The control unit 130 may control the display unit 120 and/or the notification unit 170 to visually and/or audibly notify the user of the end of warming.
