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 obtain a re-cook setting input (S110). For example, the input unit 111 of FIG. 2 may obtain a re-taking setting input from the user, and may provide a re-taking selection signal according to the re-taking setting input to the control unit 120 of FIG. 1. The controller may control the components of the cooking apparatus (eg, the heating driver 150, the sensor unit 170, and the steam discharge unit 180 of FIG. 1) so that the cooking apparatus performs the recooking according to the recooking algorithm. Can be.

The cooking apparatus may immediately perform the boiling process S120 except for the soaking process and the serving number determining step performed during the cooking according to the re-cooking algorithm. For example, the controller may control the heating driver 150 of FIG. 1 to perform a boiling process. In an embodiment, the cooking apparatus may be performed from the first stage of boiling or the second stage of boiling. Embodiments of the boiling process (S120) performed at the time of recooking will be described in detail later with reference to FIGS. 5A to 7.

After the completion of the boiling process S120, the cooking apparatus may perform the moxibustion process S130. For example, the controller may control the heating driving unit and the steam discharge unit 180 of FIG. 1 to perform the boiling process. Re-cooking may be terminated when the moxibustion process is performed. In an embodiment, the moxibustion process S130 may be omitted based on the time required for the boiling process S120.

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 performs recooking, some processes performed in the cooking algorithm, ie, soaking process and serving number determination step, are excluded. By immediately performing a boiling process, it is possible to quickly provide a high-quality cooking product.

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.

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 boiling stage 1 (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. In an embodiment, the delay step may be omitted.

6 is a flowchart illustrating an example of a boiling process of the cooking apparatus according to the embodiment of the present disclosure.

Comparing the flowchart of the boiling process of FIG. 6 with the flowchart of the boiling process of FIG. 5A, the cooking apparatus may determine whether water is added and further include an operation according to the determination result.

The cooking apparatus may sense a temperature of a cooking vessel, for example, an inner pot of an electric rice cooker or a food (S21).

The cooking appliance may determine whether water is required based on the sensing temperature (S22). 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.

When it is determined that water input is necessary, the cooking appliance may output a water input request notification signal (S23). 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 can be set (S24). The cooking appliance may set the control temperature based on the sensing temperature output in step S21. Thereafter, the cooking apparatus may perform the first boiling step S25, the delaying step S26, and the second boiling step S27. Performing the control temperature setting step (S21), boiling step 1 (S25), delay step (S26) and boiling step 2 (S27) is performed in the control temperature setting step (S12), boiling step 1 (S13), delay step of FIG. (S14) and the second boiling step (S15) similar to the duplicate description will be omitted.

In an embodiment, the cooking apparatus may determine whether water is required during the first stage of boiling (S25) and / or the second stage of boiling (S27). For example, the cooking appliance determines that water input is required when the temperature increase rate of the sensing temperature is higher than the preset temperature increase rate during heating in the boiling step 1 (S25) and / or the boiling step 2 (S27). A notification signal can be output. In step S22, the cooking apparatus may determine whether additional water is added based on the temperature increase rate during the first boiling step S25 and / or the second boiling step S27 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.

7 is a flowchart illustrating an example of a boiling process of the cooking apparatus according to the embodiment of the present disclosure. In this embodiment, the boiling process can be started from two stages of boiling.

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

The cooking appliance may set a control temperature of two boiling stages based on the sensing temperature (S32). 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), the temperature having a higher value can be set as the control temperature of the boiling two stages.

After the control temperature is set, the cooking appliance may perform two stages of boiling (S33). The cooking appliance may heat the cooking appliance, for example, an inner pot, such that the sensing temperature reaches the control temperature set in step S32 at the second boiling output. By performing two boiling steps, the boiling process can be completed. In an embodiment, as described with reference to FIG. 6, the cooking appliance determines whether water is required before the control temperature setting step S32 or during the second boiling step S33, and it is determined that water is required. By outputting a water input request notification signal, the user may request water input.

As described above, the cooking apparatus according to the present exemplary embodiment may provide a high-quality cooking product quickly by performing two boiling steps immediately when performing the re-cooking.

8 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. 8, the cooking appliance may acquire a re-cook setting input (S210). For example, the input unit 111 of FIG. 2 may obtain a re-taking setting input from the user, and may provide a re-taking selection signal according to the re-taking setting input to the control unit 120 of FIG. 1. The controller may control the cooking apparatus to perform the recooking according to the recooking algorithm.

The cooking apparatus may immediately perform the boiling process S220 except for the soaking process and the serving number determining step performed during the cooking according to the re-cooking algorithm. In an embodiment, the cooking apparatus may be performed from the first stage of boiling or the second stage of boiling.

The cooking apparatus may compare the total time required for the at least one boiling step included in the boiling process with a predetermined reference time (S230). For example, as described with reference to FIG. 5A, the cooking apparatus may compare the total time taken to perform the first and second boiling stages with the reference time when the first and second boiling stages are performed in the boiling process. Can be. As described with reference to FIG. 7, the cooking apparatus may compare the total time required to perform the second boiling step with the reference time when the second boiling step is performed in the boiling process.

If the total cooking time is less than or equal to the reference time, the cooking apparatus may perform the moxibustion process (S240). For example, the controller may control the heating driving unit 140 and the steam discharge unit 180 to perform the moxibustion process. When the total cooking time exceeds the reference time, the cooking apparatus may skip the moxibustion process and end the recooking.

As described above, according to the method of re-cooking the cooking apparatus according to the present embodiment, when the cooking apparatus performs the re-cooking, the boiling process is immediately performed except for some processes performed in the cooking algorithm, that is, the soaking process and the determination of the number of servings. By performing or omitting the moxibustion process on the basis of the total time required for the boiling step, it is possible to quickly provide a high-quality cooking product.
