<<About Operation Control by the Control Unit 30>>

Hereinafter, the characteristic operation control performed by the control part 30 in the electric cooker 10 is demonstrated. The electric cooker 10 can cook according to the operation mode selected by the user from a plurality of operation modes including the normal operation mode (the first operation mode) and the low-sugar operation mode (the second operation mode) through the operation control performed by the control unit 30 . The meal is running.

The normal operation mode is a rice cooking operation in which rice and water prepared in the inner pot 50 at a standard ratio (hereinafter, also referred to as "standard ratio") are cooked through a plurality of steps including a heating step and a boiling step. . In the electric cooker 10 of the present embodiment, the normal operation mode is a rice cooking operation in which the pre-cooking process, the heating process, the boiling process, the first stewing process, the re-cooking process, and the second stewing process are sequentially performed in sequence. model.

As shown in FIG. 5( a ), the pre-cooking step is a step of raising the temperature of the inner pot 50 to a predetermined temperature through the heating unit 24 in the initial stage of the rice cooking operation. In addition, the temperature raising process is a process performed after the pre-cooking process, and is a process of raising the output of the heating part 24 and raising the temperature of the inner pot 50 to a predetermined temperature. In addition, the boiling process is a process which operates the heating part 24 after a temperature raising process, and raises the temperature of the inner pot 50 to the boiling point of water or the temperature exceeding the boiling point of water, and boils the rice. The first stewing step is a step of stopping or suppressing the output of the heating unit 24 and stewing the rice boiled in the boiling step. In the re-cooking step, the lid side of the heating unit 24 is heated The part 24b works to re-cook the boiled rice in the inner pot 50 . The second stewing process is a process of stewing the rice in a state where the operation of the lid-side heating part 24b is completed.

The low-sugar operation mode is a rice cooking operation in which rice and water prepared in the inner pot 50 at a composition containing more water than the above-mentioned standard composition are cooked through a plurality of steps including a temperature-raising step and a boiling step. In the low-sugar operation mode, the sugar content per unit weight of cooked rice can be adjusted by adjusting the ratio of water to rice. Therefore, in the low-sugar operation mode, the electric cooker 10 can use the sugar content in the unit weight of rice cooked in the normal operation mode as a reference for the sugar content in the cooked rice per unit weight, The amount of sugar to be reduced (hereinafter, also referred to as "amount of sugar reduction") is appropriately set, and the rice cooking operation is performed. The electric cooker 10 may be configured to be capable of steplessly changing the amount of sugar reduction by the low-sugar operation mode within a predetermined range, or may be configured to be able to change the amount of sugar reduction by the low-sugar operation mode in multiple steps.

In the present embodiment, when the rice cooking operation is performed in the low-sugar operation mode, the amount of sugar reduction can be switched to two levels of 10% and 20%. In the electric cooker 10, the sugar reduction amount can be switched to two levels of 10% and 20% by operating the low-sugar rice cooking operation part 44b provided in the operation part 44. Specifically, in the electric cooker 10 of the present embodiment, the set value of the sugar reduction amount can be switched between 10% and 20% each time the operation button constituting the low-sugar rice cooking operation part 44b is pressed. . More specifically, in the electric cooker 10 of the present embodiment, the setting operation in the low-sugar operation mode can be performed according to the flow chart shown in FIG. 6 .

That is, when the setting operation in the low-sugar operation mode is performed, first, in step 1, it is checked whether any button operation (key operation) is performed on the operation unit 44 . When it is confirmed that a button operation is performed, it progresses to step 2, and it is confirmed whether the operated button is an operation button which comprises the low-sugar rice cooking operation part 44b. At Here, when it is confirmed that it is the operation of the low-sugar rice cooking operation part 44b, the control flow advances to step 3, and when it is not the operation of the low-sugar rice cooking operation part 44b, the control flow advances to step 6.

When the control flow goes to step 3, confirm whether the currently selected sugar reduction amount is 20%. Here, in the case where the current set value of the sugar reduction amount is 20%, the control flow proceeds to step 4, and the set value of the sugar content reduction amount is switched to 10%. On the other hand, in step 3, in the case where the current setting value of the sugar reduction amount is not 20%, that is, in the case where the current sugar reduction amount setting value is 10%, the control flow proceeds to step 5, where the sugar content is reduced The set value of the amount is switched to 20%.

In addition, when it is judged in the said step 2 that it is an operation other than the operation button which comprises the low-sugar rice cooking operation part 44b, a control flow advances to step 6. In step 6, it is checked whether or not the operation button detected in step 1 is an operation button constituting the operation mode selection operation part 44a or the health menu operation part 44f. Here, when it is determined that the operation button constituting the operation mode selection operation part 44a or the health menu operation part 44f is operated, the selection of the low-sugar operation mode is canceled. On the other hand, when it is determined that the operation mode selection operation unit 44a and the health menu operation unit 44f are not any of the operation mode selection operation unit 44a and the health menu operation unit 44f, the process proceeds to step 8, and the operation control corresponding to the operation button whose operation is detected is performed. In this way, the processing related to the setting operation in the low-sugar operation mode is performed in the electric cooker 10 .

In the low-sugar operation mode, the rice cooking operation is performed according to the same operation sequence as the normal operation mode described above, but the operations in some steps are different. Specifically, similarly to the normal operation mode, the rice cooking operation is performed in accordance with the operation sequence of sequentially performing the pre-cooking process, the temperature-raising process, the boiling process, the first stewing process, the re-cooking process, and the second stewing process. Here, in the low-sugar operation mode, an output restriction period is provided in the boiling process, and operation control different from the case of the normal operation mode described above is performed in this point.

Specifically, as shown in FIG. 5( b ), when the rice cooking operation is performed in the low-sugar operation mode, the control unit 30 restricts the output of the heating unit 24 during the output restriction period compared to the boiling process in the normal operation mode . More specifically, in the low-sugar operation mode, after the step of the rice-cooking operation is shifted from the temperature raising step to the boiling step, at the time when the temperature of the inner pot is assumed to reach the boiling point of water, or at a time slightly earlier than that, the output limited period is set. start. During the output limitation period, the output of the heating unit 24 is controlled by the control unit 30 so that the temperature of the inner pot 50 is shifted over time within a temperature range lower than the boiling point of water. In the electric cooker 10 of the present embodiment, when the temperature of the bottom of the inner pot 50 reaches 92° C., the output limiting period is started. During the output restriction period, the output of the heating unit 24 is controlled by the control unit 30 so that the temperature of the inner pot 50 increases with time in a temperature range lower than the boiling point of water, that is, 100° C. . By performing such output control, even if the rice cooking operation is performed by increasing the compounding amount of the water to the rice compared to the standard compounding ratio, it is possible to make the rice fully penetrate the water without overflowing. Cook rice.

Here, when the rice cooking operation is performed in the low-sugar operation mode, the amount of sugar reduction is increased or decreased according to the size of the compounding amount of the rice water. In addition, in the case where the compounding amount of water with respect to rice is large (that is, the case where the amount of sugar reduction is large) compared with the case where the compounding amount of water with respect to rice is small (that is, the case where the amount of sugar reduction is small) Allow more water to penetrate into the rice. Furthermore, the possibility of overflowing or spoiling the taste of the rice in the boiling process also varies depending on the blending amount of water. Therefore, it is desirable to precisely adjust the sugar reduction amount set by the user, the amount of rice prepared in the inner pot 50, and the amount of water to go with it.

More specifically, in the electric cooker 10 of the present embodiment, the ratio of the amount of water to the amount of rice when operating in the normal operation mode (standard ratio = amount of water/amount of rice) is defined as: 1.70 in the case of a single meter times, it is 1.6 times in the case of two-height rice, and 1.47 times in the case of three-height rice. In contrast to this, reduce the amount of sugar The standard ratio for rice cooking in the low-sugar operation mode set to 20% is stipulated as follows: 2.20 times in the case of 1-heap rice, 2.17 times in the case of 2-hem rice, and 2.17 times in the case of 3-hem rice. 1.90 times. In addition, the standard ratio for rice cooking in the low-sugar operation mode with the sugar reduction set to 10% is defined as: 2.00 times in the case of 1-gram rice, 1.85 times in the case of 2-gram rice, and 3. In the case of combined rice, it is 1.75 times. In this embodiment, the inner wall surface of the inner pot 50 is provided with a scale as an indicator of the water level so that the optimum water amount can be known from the amount of sugar reduction and the amount of rice (combined number) used for cooking. In the electric cooker 10 of the present embodiment, the control unit 30 performs the above-described operation control on the assumption that an appropriate amount of water is prepared according to the amount of sugar reduction and the amount of rice using the scale attached to the inner pot 50 as an index. In this way, the electric cooker 10 can suppress overflow and deterioration of food taste, etc., and can cook rice that satisfies the sugar reduction amount set by the user.

The control unit 30 exports the length of the output restriction period and the output restriction period to the inner pot 50 based on the amount of rice prepared in the inner pot 50 and the sugar reduction amount (in other words, the sugar content in the cooked rice is assumed). Or the heat applied by rice, water, etc. prepared in the inner pot 50 (output of the heating part 24). The control part 30 controls the operation|movement concerning the rice cooking operation so that the length of the output restriction period and the output of the heating part 24 which are exported in this way may be satisfied.

When the rice cooking operation is performed in the low-sugar operation mode, the control unit 30 controls the output of the heating unit 24 so that the temperature of the inner pot becomes higher than the boiling point of water after a predetermined time elapses after the output restriction period ends. Thereby, the water remaining in the inner pot 50 is evaporated, and the rice is cooked thoroughly.

As described above, the electric cooker 10 of the present embodiment can perform rice cooking operation using rice and water prepared in a ratio containing more water than in the normal operation mode by selecting the low-sugar operation mode provided separately from the normal operation mode. . Moreover, the electric cooker 10 is comprised so that an output limitation period may be provided in the boiling process in a low sugar operation mode, and a rice cooking operation may be performed. In this way, by setting the output limit period and performing the rice cooking operation, it is possible to enough to allow moisture to penetrate into the rice. Thereby, the sugar content per unit weight of rice can be suppressed, and the taste of the rice which is not inferior to the rice cooking operation in the normal operation mode can be produced. Therefore, according to the electric cooker 10 described above, the sugar content per unit weight of rice can be easily adjusted without adding an additional configuration.

In addition, as described above, in the electric cooker 10, the output restriction period starts from the time when it is assumed that the temperature of the inner pot 50 reaches the boiling point of water or a time slightly earlier than the time. By starting the output restriction period at the above-mentioned timing and restricting the output of the heating unit 24, it is possible to suppress overflow during the rice cooking operation in the low-sugar operation mode, and to allow moisture to penetrate into the rice.

In addition, in the present embodiment, the configuration in which the output restriction period is started based on the assumption that the temperature of the inner pot 50 reaches the boiling point of water is exemplified, but the present invention is not limited to this. For example, the output limited period may be started at another time based on the temperature of the inner pot 50 , or the start time of the output limited period may be defined according to the change in the internal pressure of the inner pot 50 .

As described above, the electric cooker 10 is configured to be able to change the ratio of the rice and water prepared in the inner pot 50 within a predetermined range to perform rice cooking in the low-sugar operation mode, and to increase the amount of water to rice in response to an increase in the blending amount. Instead, adjust the length of the output limit period. Specifically, the electric cooker 10 is configured to be able to perform rice cooking in the low-sugar operation mode by changing the mixture ratio of rice and water prepared in the inner pot 50 within a predetermined range according to the amount of sugar reduction, and based on the amount of water to be added. Change the amount of sugar limit to adjust the length of the output limit period. Thereby, the length of the output restriction period can be adjusted to a length suitable for rice cooking by permeating moisture into the rice.

As described above, the electric cooker 10 is configured to increase the temperature of the inner pot 50 over time in a temperature range lower than the boiling point of water during the output limitation period during rice cooking in the low-sugar operation mode. rise In this way, the output of the heating unit 24 is controlled. Therefore, in the electric cooker 10 , when the rice cooking operation is performed in the low-sugar operation mode, the occurrence of overflow during the output restriction period can be suppressed, and the water can be permeated into the rice. Thereby, the sugar content per unit weight of the rice can be suppressed, and the taste of the rice which is not inferior to the rice cooking operation performed in the normal operation mode can be produced.

In addition, as described above, the electric cooker 10 is configured so that the temperature of the cooker 50 becomes higher than the boiling point of water after a predetermined time elapses after the output restriction period ends during rice cooking in the low-sugar operation mode. The output of the heating unit 24 is controlled. Thereby, it is possible to thoroughly cook the rice by vaporizing the remaining moisture that does not penetrate into the rice with the end of the output restriction period, and the like. Thereby, it is possible to produce delicious rice with a reduced sugar content. In addition, in the present embodiment, the output of the heating unit 24 is controlled so that the temperature of the inner pot 50 becomes higher than the boiling point of water after the output restriction period ends, but the present invention is not limited to this. That is, for example, when it is not necessary to vaporize the remaining moisture after the output limitation period ends, the electric cooker 10 may be configured so as not to perform the output control of the heating unit 24 as described above after the output limitation period ends.

As described above, the electric cooker 10 is configured such that the operation conditions of the rice cooking operation can be selected based on the sugar content (sugar content limit), and the rice and rice cooking operation for realizing the rice cooking operation under the selected operation conditions The output limit period is set according to the proportion of water. Therefore, according to the electric cooker 10 described above, the rice cooking operation can be performed so that the sugar content per unit weight of the rice becomes the sugar content set as the operation condition of the rice cooking operation. In addition, since the electric cooker 10 of the present embodiment selects the sugar limit amount from two kinds of 10% and 20%, the output limit period can be exported and set in advance in the manufacturing stage or the like, but the present invention is not limited to this. . Specifically, for example, when the amount of sugar (limited sugar) contained in cooked rice can be set to infinite or multiple levels, it is difficult to predetermine the most suitable rice based on the amount of rice and the amount of sugar (limited sugar) In the case of the ratio of water and the output limit period, etc., it can be formed so that the control unit 30 can be used for cooking according to the The prepared amount of rice is exported and notified of conditions such as the amount of water to be put into the inner pot 50 and the length of the output restriction period. In this way, it is possible to obtain products suitable for use even if the amount of rice for rice cooking, sugar content (limited sugar content), etc. are changed to arbitrary values without being restricted by predetermined values such as the sugar content (sugar content limit), which is predetermined. The amount of sugar requested by the user (sugar limit) of rice.

As described above, when the rice cooking operation is performed in the low-sugar operation mode, the amount of sugar contained in the cooked rice varies depending on the amount of water to be prepared with respect to the rice. In the electric cooker 10 exemplified in the above-described embodiment, an example in which the amount of water can be adjusted according to the amount of rice for cooking is shown by using the scale attached to the inner pot 50 as an index or the like, but the present invention is not limited to this.
