As shown in FIG. 3, at each step included in the soaking process, the heating process, and the moxibustion process, the heating method, time, control temperature, and pressure valve control method may be different.

The soaking process may include a soak heating section for heating rice and water contained in an inner pot of a cooking device such as an electric rice cooker to a predetermined soaking temperature, and a soaking waiting section for waiting for a predetermined soaking time while maintaining the soaking temperature. have.

The heating process may include a phosphorus determination step and a boiling process. In the phosphorus determination step, the heating unit 160 of FIG. 1 heats the cooking vessel with a constant heating output, and the speed of change of the sensing temperature at which the control unit 120 of FIG. 1 senses the temperature of the lower portion of the inner pot or the food, For example, the amount of rice and water in the inner pot (that is, phosphorus water) can be determined based on the temperature increase rate.

The boiling process includes a boiling stage 1 heating the inner pot so that the sensing temperature reaches the first boiling temperature (ie, the control temperature of the boiling stage 1) at the first boiling output, and the sensing temperature is the second boiling temperature ( That is, it may include a boiling step 2 for heating the inner pot to reach the control temperature of the boiling step 2). In this case, the second boiling temperature may be higher than the first boiling temperature. The heating time can be set for each of the first stage of boiling and the second stage of boiling. If the sensing temperature reaches the first boiling temperature or the heating time set for the boiling first stage has elapsed, the boiling first stage can be ended. The boiling second stage may end when the sensing temperature reaches the second boiling temperature or when the heating time set for the second boiling stage has elapsed.

The boiling process may include a delay step of maintaining the sensing temperature at a predetermined temperature (that is, the control temperature of the delay step) between the boiling step 1 and the boiling step 2 for a predetermined time. The control temperature of the delay stage may be lower than the first boiling temperature and the second boiling temperature.

The moxibustion process is a process of slowly cooking rice cooked by heating at a high temperature and high pressure in a boiling process to complete cooking that produces the best rice taste.

For example, the heating method, time, control temperature, and pressure valve control method of the steps included in each process may be varied according to the cooking menu.

4 is a flowchart schematically illustrating a method of re-cooking a cooking apparatus according to an exemplary embodiment of the present disclosure.

Referring to FIG. 4, the cooking appliance (100 of FIG. 1) may acquire a re-cooking and step setting input (S110). For example, the input unit 111 of FIG. 2 obtains the re-taking setting input from the user and the step setting input according to the rapid step selection of the re-taking, and controls the re-selection selection signal and the step selection signal according to the re-taking and the step setting input. 1, 120).

The cooking appliance may determine the selected rapid stage based on the stage setting input (S120). The cooking appliance may perform a boiling process according to the selected rapid stage (S130). When performing the boiling process, the control unit controls the components of the cooking apparatus (eg, the heating driving unit 150, the sensor unit 170, and the steam discharge of the cooking apparatus so that the cooking apparatus performs the recooking according to the recooking algorithm and the selected step). The unit 180 may be controlled.

In detail, the controller may determine whether the step selection input indicates one step (S121). When the step selection input indicates one step, the cooking appliance may perform the first boiling step (S131). The controller may control the heating driver (150 of FIG. 1) based on the setting for the boiling stage 1 and the sensing temperature.

If the step selection input does not indicate one step, the controller may determine whether the step selection input indicates two steps (S122). When the step selection input indicates two steps or after the first boiling step is performed, the cooking appliance may perform a delay step (S132). The controller may control the heating driver based on the setting for the delay step and the sensing temperature.

If the step selection input does not represent the second step, or after the delay step is performed, the cooking appliance may perform the second boiling step (S133). The controller may control the heating driver based on the setting for the two boiling stages and the sensing temperature. Re-cooking may end when the second boiling step is performed.

As described above, according to the method of recooking a cooking apparatus according to an exemplary embodiment of the present disclosure, according to a recooking algorithm when the cooking apparatus is recooked, some processes performed in the cooking algorithm except for a soaking process and a moxibustion process are boiling. The process can be carried out. In addition, a step selected by the user, that is, a selection step selected according to the step setting input, may be performed from among a plurality of steps of the boiling process performed sequentially. Therefore, the cooking apparatus according to the embodiment of the present disclosure may provide a high-quality cooking quickly by performing the recooking according to the recooking algorithm and the rapid step selected by the user.

5A is a flowchart illustrating an example of a boiling process of a cooking apparatus according to an exemplary embodiment of the present disclosure, and FIG. 5B is a flowchart illustrating a control temperature setting step of FIG. 5A. 5A shows the case where the step selection input indicates one step, that is, when the boiling process starts from the first boiling step.

Referring to FIG. 5A, the cooking device (100 of FIG. 1) may sense a temperature of a cooking vessel, for example, an inner pot of a rice cooker or a food (S11). For example, the lower sensor of the sensor unit 170 of FIG. 1 may sense the lower temperature of the inner pot or the temperature of the food. The sensing result may be output as the sensing temperature.

The cooking appliance may set the control temperature of the boiling stage 1 based on the sensing temperature (S12). In an embodiment, the control unit 120 of FIG. 1 may set the control temperature, that is, the first boiling temperature, based on the sensing temperature output from the sensor unit. Referring to FIG. 5B, the controller may generate a comparison temperature by adding a predetermined first temperature (eg, a temperature between 10 degrees and 20 degrees) to the sensing temperature (S1). The controller may compare the control temperature (for example, the first boiling temperature set when cooking) with respect to the comparison temperature and the first boiling step (S2). If the comparison temperature is higher than the preset control temperature, the comparison temperature may be reset to the control temperature (S3). If the comparison temperature is not higher than the preset control temperature, it is possible to maintain the preset control temperature (S4). For example, if the sensing temperature is 100 degrees, the predetermined temperature is 20 degrees, and the preset control temperature for the boiling stage 1 is 110 degrees, the comparison temperature is 120 degrees and is higher than the preset control temperature 110 degrees, The comparison temperature 120 degrees may be set as the first boiling temperature. As another example, when the sensing temperature is 80 degrees, the predetermined temperature is 20 degrees, and the preset control temperature for the boiling stage 1 is 110 degrees, the comparison temperature is 100 degrees and lower than the preset control temperature 110 degrees, 110 degrees, which is a preset control temperature, may be set (ie, maintained) as the control temperature. As such, the controller may set a temperature having a higher value among the comparison temperature and the preset control temperature as the control temperature for boiling one stage.

When the temperature of the cooked food, that is, the sensing temperature is higher than the preset control temperature beam for the boiling stage 1, the boiling stage 1 may be omitted. However, the cooking apparatus according to the embodiment of the present disclosure sets the control temperature of the boiling stage 1 performed at the time of reboiling by comparing the sensing temperature obtained by adding the predetermined first temperature to the sensing temperature and the preset control temperature, thereby boiling 1 The step can be prevented from being omitted.

5A, the cooking appliance may perform a boiling step 1 (S13). The cooking appliance may heat the inner pot so that the sensing temperature reaches the control temperature set in step S12 with the first boiling output. For example, under the control of the control unit, the heating driver (150 in FIG. 1) adjusts the power applied to the heating unit (160 in FIG. 1), thereby providing heat to the food at the set heating output, that is, the first boiling output. Can be. The controller may end the boiling stage 1 when the sensing temperature reaches the control temperature or when the time set for the boiling stage 1 has elapsed.

The cooking appliance may perform a delaying step (S14). For example, the controller may control the heating driver to maintain the sensing temperature at a predetermined temperature. The controller may end the delay step when the time set for the delay step has elapsed.

Thereafter, the cooking apparatus may perform a boiling step 2 (S15). The cooking appliance may heat the inner pot so that the sensing temperature reaches a preset control temperature (eg, the second boiling temperature) at the second boiling output. For example, by controlling the power applied to the heating unit under the control of the control unit, the heating unit may provide heat to the food at the set heating output, that is, the second boiling output. The controller may end the second boiling stage when the sensing temperature reaches the second boiling temperature or when the time set for the second boiling stage elapses. After the two boiling steps are performed, the boiling process can be completed.

6 is a flowchart illustrating an example of a boiling process of the cooking apparatus according to the embodiment of the present disclosure. 6 shows the case where the step selection input represents two stages, that is, the boiling process starts from the two stages of boiling.

Referring to FIG. 6, the cooking apparatus may sense a temperature of a lower portion of an inner pot of a cooking container, for example, an electric rice cooker or a food (S21).

The cooking appliance may set a control temperature of two boiling stages based on the sensing temperature (S22). In an embodiment, the control unit 120 of FIG. 1 may set the control temperature of the second boiling stage, that is, the second boiling temperature, based on the sensing temperature output from the sensor unit. The control unit generates a comparison temperature by adding a predetermined first temperature (for example, a temperature between 10 degrees and 20 degrees) to the sensing temperature similarly as described with reference to FIG. 5B, and the control temperature preset for the comparison temperature and the second boiling stage. (Eg, the second boiling temperature set at the time of cooking), a temperature having a higher value may be set as a control temperature of two boiling stages.

After the control temperature is set, the cooking appliance may perform two stages of boiling (S23). The cooking appliance may heat the cooking appliance, such as an inner pot, so that the sensing temperature reaches the control temperature set in step S22 at the second boiling output. By performing two boiling steps, the boiling process can be completed.

7A to 7C are flowcharts illustrating embodiments of a boiling process of the cooking apparatus according to the embodiment of the present disclosure.

FIG. 7A shows the case where the step select input indicates one stage, that is, when the boiling process starts from the first stage of boiling, and FIG. 7B shows the case where the step select input indicates two stages, that is, when the boiling process starts from the delay stage. 7C shows the case where the step selection input indicates three stages, that is, the boiling process starts from the two boiling stages.

First, comparing the flowchart of the boiling process of FIG. 7A with the flowchart of the boiling process of FIG. 5A, the cooking apparatus may determine whether water is added, and may further include an operation according to the determination result.

Referring to FIG. 7A, the cooking apparatus may sense a temperature of a lower portion of an inner pot of a cooking container, for example, an electric rice cooker or a food (S31).

The cooking appliance may determine whether water is required based on the sensing temperature (S32). In an embodiment, the control unit 120 of FIG. 1 is configured to sense that the sensing temperature is higher than a predetermined reference temperature set for the boiling stage 1 (eg, 10 to 20 degrees lower than the preset control temperature for the boiling stage 1). Alternatively, if the sensing temperature is higher than the preset control temperature for the first boiling stage, it may be determined that water input is necessary when omission of the first boiling stage is expected.

If it is determined that water input is necessary, the cooking appliance may output a water input request notification signal (S33). For example, under the control of the controller 120, the display unit 112 and / or the voice output unit 113 may output a water input request and a notification signal to mix water with rice.

If it is determined that no water input is required, or after the water input is detected after the water input request notification signal is output or after a predetermined time (for example, the water input waiting time) has elapsed, the cooking appliance is heated based on the sensing temperature. The control temperature of the step may be set (S34). The cooking appliance may set the control temperature based on the sensing temperature output in step S31. Thereafter, the cooking apparatus may perform the first boiling step S35, the delaying step S36, and the second boiling step S37. Performing the control temperature setting step S31, the boiling first step S35, the delaying step S36, and the boiling second step S37 is performed by the control temperature setting step S12, the boiling first step S13, and the delaying step of FIG. (S14) and boiling two stages (S15). Therefore, duplicate descriptions will be omitted.

In an embodiment, the cooking appliance may determine whether water is required during the first boiling step S35 and / or the second boiling step S37. For example, the cooking appliance determines that the water input is necessary when the heating rate of the sensing temperature is higher than the preset reference heating rate during heating in the boiling step 1 (S35) and / or the boiling step 2 (S37). The request notification signal may be output. In step S32, the cooking apparatus may determine whether additional water is added on the basis of the temperature increase rate during the first boiling step S35 and / or the second boiling step S37.

Referring to FIG. 7B, the cooking apparatus may sense a temperature of a lower portion of the inner pot of the cooking vessel, for example, an electric rice cooker or the food (S41).

The cooking appliance may determine whether water is required based on the sensing temperature (S42). In an embodiment, the controller (120 of FIG. 1) is configured to provide water when the sensing temperature is higher than a predetermined reference temperature set for the delay step (e.g., 10 degrees to 20 degrees lower than the preset control temperature for the delay step). It can be determined that input is necessary.

When it is determined that water input is necessary, the cooking apparatus may output a water input request notification signal (S43).

If it is determined that no water input is necessary, or after the water input is detected after outputting the water input request notification signal or after a predetermined time (for example, the water input waiting time) has elapsed, the cooking apparatus is subjected to a delay step S44 and boiling. Step 2 (S45) may be performed in sequence.

Referring to FIG. 7C, the cooking apparatus may sense a temperature of a cooking vessel, for example, an inner pot of an electric rice cooker or a food (S51).

The cooking appliance may determine whether water is required based on the sensing temperature (S52). In an embodiment, the control unit (120 of FIG. 1) is a case in which the sensing temperature is higher than a predetermined reference temperature (e.g., 10 to 20 degrees lower than the preset control temperature for the two boiling stages). Alternatively, when the sensing temperature is higher than the preset control temperature for the two boiling stages, it may be determined that water input is necessary when the second boiling stage is expected to be omitted.

When it is determined that water is required, the cooking appliance may output a water input request notification signal (S53). If it is determined that no water input is required, or after the water input is detected after outputting the water input request notification signal or a predetermined time (for example, the water input waiting time) has elapsed, the cooking appliance is boiling based on the sensing temperature. The control temperature of the step can be set (S54). The cooking appliance may set the control temperature based on the sensing temperature output in step S51. Thereafter, the cooking appliance may perform a second boiling step S55.

In an embodiment, the cooking appliance may determine whether water is required during the second stage of boiling (S55). For example, the cooking appliance may determine that water input is necessary and output a water input request notification signal when the heating rate of the sensing temperature is higher than the preset reference temperature rising rate during heating in the second boiling step S55. In step S52, the cooking apparatus may determine whether additional water is added based on the temperature increase rate during the boiling second step S55 even after determining whether water is required.

As described above, the cooking apparatus according to the present embodiment determines whether water is added based on the sensing temperature, that is, the temperature of the food or the temperature increase rate, and if it is determined that water is required, requesting the user to add water to re-cook the water. During the process, the moisture of the food may be excessively removed or the cooking may be prevented from burning.

Referring to FIG. 8, the cooking appliance (100 of FIG. 1) may obtain a re-cooking and step setting input (S210). For example, the input unit 111 of FIG. 2 obtains the re-taking setting input from the user and the step setting input according to the rapid step selection of the re-taking, and controls the re-selection selection signal and the step selection signal according to the re-taking and the step setting input. 1, 120).

The cooking appliance may determine the selected rapid stage based on the stage setting input (S220). The cooking appliance may perform a boiling process according to the selected rapid stage (S230). When the boiling process is performed, the control unit may control the components of the cooking apparatus (eg, the user interface 110 of FIG. 1, the heating driver 150, and the sensor unit) so that the cooking apparatus performs the recooking according to the recooking algorithm and the selected step. 170, and the vapor discharge unit 180 may be controlled.

In detail, the controller may determine whether the step selection input indicates one step (S221). When the step selection input indicates the first step, the cooking appliance outputs a water input request notification signal (S231). A boiling step 1 may be performed (S231). For example, under the control of the controller 120, the display unit 112 and / or the voice output unit 113 may output a water input request and a notification signal to mix water with rice. After the water input is detected or after a predetermined time (for example, the water input waiting time) has elapsed after outputting the water input request notification signal, the controller controls the heating driver based on the setting and sensing temperature for the first stage of boiling (150 in FIG. 1). ), One step of boiling can be performed. In this case, as described with reference to FIG. 5B, the controller may set the control temperature of the boiling stage 1 based on the sensing temperature output from the sensor unit 170.

If the step selection input does not indicate one step, the controller may determine whether the step selection input indicates two steps (S222). When the step selection input indicates two steps or after the first boiling step is performed, the cooking appliance may output a water input request notification signal (S233) and perform a delay step (S132). For example, the controller outputs a water input request notification signal, and after the water input is detected or after a predetermined time (for example, the water input waiting time) has elapsed, by controlling the heating driver based on the setting for the delay step and the sensing temperature, Delay steps can be performed.

If the step selection input does not indicate two steps, or after the delay step is performed, the cooking appliance may perform two boiling steps (S235). The controller may perform the second boiling step by controlling the heating driver based on the setting for the second boiling step and the sensing temperature. In this case, as described with reference to FIG. 5B, the controller may set a control temperature of two boiling stages based on the sensing temperature output from the sensor unit. Re-cooking may end when the second boiling step is performed.

According to the present embodiment, when performed from the first boiling stage or the delay stage according to the step selection input, the cooking appliance may output a water input request notification signal. However, when performed from the second boiling step, the cooking appliance may not output the water input request notification signal. That is, the cooking appliance may selectively output the water input request notification signal according to the rapidity selected by the user.

9 is a flowchart illustrating a method of operating a cooking apparatus according to an embodiment of the present disclosure.

Referring to FIG. 9, the cooking apparatus may acquire a cooking setting input in operation S310. For example, the input unit 111 of FIG. 2 may acquire the cooking setting input from the user, and may provide the cooking selection signal according to the cooking setting input to the controller 120 of FIG. 1. The cooking setting input may include an input for selecting one of various kinds of cooking menus such as “white rice,” “cauldron rice,” “simmered rice,” “dried rice,” “grain rice,” and “germinated brown rice”. have. The controller may control the cooking apparatus to perform cooking according to a standard cooking algorithm of the selected menu.

According to the cooking algorithm, the cooking apparatus may perform a soaking process S320, a boiling process S330, and a moxibustion process S340. The boiling process 330 may include a first boiling step S331, a delaying step S332, and a second boiling step S333, which are sequentially performed. When the moxibustion process (S340) is completed, cooking may be terminated (S350).

After cooking is finished, the cooking apparatus may determine whether re-cooking and step setting input are obtained (S360). That is, it may be checked whether the user has selected the re-cooking function.

If the re-taking and the step setting input are obtained, the cooking appliance may check the step (S370). As described with reference to FIG. 4, the controller (120 of FIG. 1) may check whether the step selection signal according to the step setting input indicates any of a plurality of steps, for example, steps 1, 2, and 3.

The cooking appliance may perform the recooking according to the recooking algorithm and the selected step. The re-cooking algorithm may be a re-cooking algorithm for a menu selected during the cooking or a menu predetermined for the re-cooking. For each menu, the settings for the process performed according to the recooking algorithm (eg, heating method, time, control temperature, etc.) may be similar to the settings of the same process performed according to the cooking algorithm of the same menu.

As shown, the cooking apparatus may perform the boiling process S330 except for the soaking process S320 and the moxibustion process S340, and a plurality of stages of the boiling process S330, for example, a boiling stage 1. According to the steps identified in step S370 of step S331, the second boiling step S332, and the third boiling step S333, the selected step among the plurality of steps and subsequent steps thereof may be performed. For example, when the step selection signal indicates one step, the boiling step 1 (S331) to the delay step (S332) and the boiling step 2 (S332) is performed, and when the step selection signal indicates the second step, the delay step (S332) To the second boiling step S332, and when the step selection signal indicates three steps, the second boiling step S333 may be performed. At this time, the boiling process may be performed as described with reference to FIGS. 5A to 7.

After the second boiling step S333 is finished, re-cooking may be ended. That is, when performing re-cooking, the moxibustion process (S340) may be omitted. Thereafter, the cooking appliance may determine whether a re-cooking and step setting input are obtained (S360). That is, it may be checked whether the user has additionally selected the re-cooking function. If additional re-cutting and step setting input have been obtained, further re-cutting may be performed, according to the re-cutting algorithm, as described above. If there is no additional re-taking and step setting input, the cooking appliance may stop the operation or perform the warming operation.
