Abstract

PROBLEM TO BE SOLVED: To enable reliable setting of a cooking course suitable for the state of an ingredient being cooked or a result of cooking expected by a user.SOLUTION: A heating cooker has course options for selecting a cooking course. When power is supplied from a commercial power supply, the heating cooker shifts to an initial setting mode where a selection state of the course options can be changed and a cooking cannot be started until the initial setting mode ends. Thus, a user will inevitably select a cooking course before starting cooking after power is turned on.

Description

  The present invention relates to a heating cooker provided with a plurality of cooking courses.

  Conventionally, this type of cooking device has various rice cooking menus such as white rice, brown rice, rice porridge, rice bran, etc., and has an operation panel provided with a liquid crystal display, a course selection switch, and a rice cooking switch, and is on standby. When there is an input from the course selection switch on the screen, a transition is made to a course menu selection screen, and a cooking course can be selected on the selection screen (for example, Patent Document 1).

JP 2007-50039 A

However, in the conventional configuration, it is possible for the user to start cooking without changing the setting of the cooking course, so that the user can change the cooking course state or the cooking result expected by the user and the cooking course. Therefore, there is a problem that the cooking course does not always coincide with the cooking course when the cooking is started, and the cooking may fail or the taste may be deteriorated without heating cooking intended by the user.
The present invention solves the above-described conventional problems, and an object thereof is to ensure that a cooking course suitable for the state of a cooked product or the cooking result expected by a user is set.

  In order to solve the conventional problem, the cooking device of the present invention displays a plurality of cooking courses, course options for selecting at least a part of the cooking course, and a selection state of the course options. A change operation unit for instructing to change the selection state, a start operation unit for instructing start of cooking according to a cooking course corresponding to the selected course option, the change operation unit, and the start A control unit that inputs an instruction operation from an operation unit and displays the selection state on the display unit, and the control unit is selected at a predetermined or last time when power from a commercial power source is supplied. The selection state is displayed on the display unit, and the initial operation mode is changed to the initial setting mode in which the selection state can be changed by the operation of the change operation unit. In which al instruction operation has not to start the cooking be input.

  Thus, when the user turns on the commercial power, the user goes through an initial setting mode for selecting a cooking menu before starting cooking.

  According to the present invention, a cooking course suitable for the state of the cooked product or the cooking result expected by the user is reliably set.

1st invention carries out instruction | indication operation of the change of the said selection state, the display part which displays the selection of the several cooking course, the course option for selecting at least one part of the said cooking course, and the said course option Change operation part,
A start operation unit for instructing start of cooking according to the cooking course corresponding to the selected course option, an instruction operation from the change operation unit and the start operation unit, and the selection on the display unit A control unit that displays a state, and when the power from a commercial power source is supplied, the control unit displays the selected state selected at a predetermined or last time on the display unit, and performs the change operation. Shifting to an initial setting mode in which the selection state can be changed by an operation of the unit, and cooking is not started during the initial setting mode even if an instruction operation is input from the start operation unit. As a result, the user always selects the cooking course before turning on the commercial power and starting cooking.For example, when the user is not connected to the commercial power source for a long period of time or when the cooking device is not connected. If the user is unlikely to remember or know the previous cooking course selection status, such as when lending or giving to a user, the user does not have to select the cooking course. It is possible to prevent cooking from being started at a setting of a cooking course that is contrary to the user's intention, and to reduce the possibility of heating cooking inappropriate for the user or the food.

  In the second invention, in particular, in the initial setting mode of the first invention, the control unit displays a display indicating an operation method for changing the selection state on the display unit. As a result, the user can be informed that it is necessary to select the course option after turning on the commercial power, and the operation method for selecting the course option is displayed in an easy-to-understand manner so that the user does not feel resistance. It is possible to prompt selection of an option, and it is possible to increase the possibility that the user can select the course option without forgetting it immediately after the commercial power is turned on.

  According to a third aspect of the invention, in particular, in the first or second aspect of the invention, when the control unit finishes the initial setting mode, the power from the commercial power source is once again stopped after the supply of power from the commercial power source is stopped. Even if is supplied, the initial setting mode is not changed. As a result, if the user selects the course option only when the cooking device is used for the first time, when the power from the commercial power source is supplied after the next time, the user does not need to select the course option. You can start cooking immediately at a cooking course that is likely to be done, for example, setting according to the season such as new rice, old rice, setting according to the period until brand rice purchased in large bags is used up, or When using the same setting continuously, such as the preference of cooking with power saving or priority on taste, etc., when changing the setting operation each time or cooking temporarily The operation of re-setting the original cooking course can be omitted.

  In a fourth aspect of the invention, in particular, in any one of the first to third aspects of the invention, the plurality of cooking courses include a non-cooking course whose purpose is different from cooking ingredients, and the course options are the The non-cooking course was not included. As a result, cooking courses that cannot be selected when cooking are not displayed as course choices when the commercial power is turned on, or even if displayed, they cannot be selected, and the selection operation of course choices is simplified. Can do.

Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment shown below exemplifies a heating cooker for specifically realizing the technical idea of the present invention, and intends to specify the present invention as this heating cooker. Rather, it is equally applicable to the other embodiments included in the claims.

The bottom induction heating coil 4 is provided in the vicinity of the bottom of the pan 2, and heats the pan 2 by induction heating. The bottom sensor 5 is provided in contact with the center of the bottom surface of the pan 2, detects the temperature of the bottom surface of the pan 2, and sends temperature information to the control unit 9. The control unit 9 controls the energization amount of the bottom induction heating coil 4 based on the temperature information of the bottom sensor 5 and changes the heating amount of the pan 2 to control the temperature of the pan 2 to a temperature suitable for cooking. It is composed. The upper portion of the main body 1 is covered with an openable / closable lid 3 that is pivotally supported by a hinge shaft 8 provided on a hinge portion 7 at the rear of the main body 1. An operation panel 6 as shown in FIG. 2 is provided on the top of the lid 3.

  FIG. 2 is a diagram showing an operation panel according to the first embodiment of the present invention. The operation panel 6 is provided with a display unit 10 having a sufficiently large and large display area. Around the display unit 10, a determination / function switch 11a, a lower switch 11b, an upper switch 11c, a cancel / off switch 11d, a reservation switch 11e, Various operation switches such as a rice cooking switch 11f, a rice switch 11g, a cooking method switch 11h, and a steam heat retention / reheating switch 11i are disposed.

  A control unit 9 is provided below the operation panel 6.

  FIG. 3 is a block diagram of the control unit 9 according to the first embodiment of the present invention. The control unit 9 is controlled when a control unit 12 composed of electric circuit components such as a microcomputer, a drive power source 14 that supplies power supplied from a commercial power source to the control unit 12, and when no power is supplied from the drive power source 14. The display unit 10 is connected to the control unit 12 and is integrated with the control unit 12 through a synthetic resin holder. The backup power source 13 is configured by a storage battery that supplies power to the unit 12. Has been. The control unit 12 displays an appropriate display on the display unit 10 in accordance with the user's instruction operation input from each of the input switches 11a to 11i, and selects a cooking course, and a heating pattern corresponding to the selected cooking course. The cooking control by is done.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  FIG. 4 is an operation flowchart at power-on in the first embodiment of the present invention.

  First, when power is supplied from a commercial power source, the control unit 12 displays a greeting screen on the display unit 10 in step S1, and proceeds to step S2. FIG. 5 shows a display example of the greeting screen. In FIG. 5, the current time is displayed, and a greeting word corresponding to the time zone of the current time and a symbol indicating the time zone are displayed. For example, if the current time is a night time zone, the greeting word “Good evening” is displayed instead of the greeting word “Good morning”, and the symbol “Crescent moon” is displayed instead of the symbol “Sun”.

  In step S2, time is measured, and when 3 seconds have elapsed, the process proceeds to step S3.

In step S3, it is determined whether or not the control unit 12 has finished the initial setting mode before. If the initial setting mode has not been finished, the process proceeds to the initial setting mode in step S4 and thereafter, and the initial setting is performed. If the mode has been completed, the process proceeds to step S12. In order to determine whether or not the initial setting mode has been completed before, it is necessary to store an end flag or corresponding history information when the initial setting mode is ended. Since the backup power supply 13 is provided in the present embodiment, even if recording is performed in the RAM, even if the power supply from the commercial power supply is interrupted, the storage is not erased. Absent.

  In step S4, an initial setting guide screen is displayed on the display unit 10, and the process proceeds to step S5. FIG. 6 is a diagram showing a display example of the initial setting guidance screen. Although “Thank you for your purchase” is displayed in FIG. 6, the initial setting guidance screen is usually displayed when the commercial power is turned on for the first time after purchasing the product. Is displayed to draw the user's attention. In addition, regarding the display of “Eco-cooking”, consider whether to change the “eco-cooking” displayed as the setting of the cooking course that the user wants to set continuously. And has the effect of directing consciousness to the subsequent steps. These displays can prevent the user from leaving the cooking device at this point.

  In step S5, time is measured, and when 4 seconds have elapsed, the process proceeds to step S6.

  In step S6, the selection state of the course options for setting the cooking course and the operation guide are displayed on the display unit 10, and the process proceeds to step S7. FIG. 7 is a diagram showing a selection state of the cooking course in the initial setting mode. FIG. 7A is a screen displayed on the display unit 10 in step S6, and shows a state where “eco-cooking” shown in the display of FIG. 6 is selected.

  In step S7, it is determined whether or not the upper switch 11c has been operated. If it has been operated, the process proceeds to step S8, and if not, the process proceeds to step S9.

  In step S8, since it is determined that the upper switch 11c has been operated, a cooking course that is one higher than the selected cooking course is selected. However, in the state where the uppermost course option of the selectable course options is selected, there is no upper course option, and therefore the lowermost course option is selected. In this way, even when there are a large number of course choices, it is possible to move from the uppermost course to the lowermost course with only one switch operation, so that the selection operation is simplified. In this embodiment, as shown in FIGS. 7A and 7B, there are only two course options, “eco-cooking” and “silver shari”, and “eco-cooking” is the top course option. When the upper switch 11c is operated when "" is selected, the cooking course of "Silver Shari" which is the lowest course option is selected, and the process proceeds to step S7.

  On the other hand, in step S9, which is shifted to when the upper switch 11c is not operated in step S7, it is determined whether or not the lower switch 11b is operated. If it is operated, the process proceeds to step S10, and if it is not operated. Proceed to step S11.

  In step S10, since it is determined that the lower switch 11b has been operated, a cooking course that is one lower than the selected cooking course is selected. However, in the state where the lowest course option of the selectable course options is selected, there is no course option below, so the top course option is selected. By doing this, even when there are many course choices, it is possible to move from the lowest course to the highest course with only one switch operation, so that the selection operation is simplified. In the present embodiment, as shown in FIG. 7B, when “silver shari” which is the lowest course option is selected, when the lower switch 11b is operated, “eco-cooking” which is the top course option is selected. "" Is selected, and the process proceeds to step S7.

On the other hand, in step S11, which is shifted to when the lower switch 11b is not operated in step S9, it is determined whether or not the decision / function switch 11a is operated, and if it is operated, the process proceeds to the standby mode of step S12. If not operated, the process proceeds to step S7, and the operation state of each switch is confirmed again. Thus, in the present embodiment, in the initial setting mode from step S4 to step S11, only the operation of the upper switch 11c, the lower switch 11b, and the determination / function switch 11a is valid, and the other switches The operation is not accepted. This can prompt the user to consciously select and operate the cooking course in the initial setting mode, and does not unconsciously operate the rice cooking switch 11f to start cooking on a cooking course different from the user's intention. You can

  In step S12, the control part 12 memorize | stores the conditions that the initial setting mode was complete | finished, displays the standby screen comprised by the presently selected cooking course and the present time on the display part 10, and input from the rice cooking switch 11f stand by. FIG. 8 is a diagram showing a display example of the standby screen. FIG. 8A is an example of a standby screen when “eco-cooking” is selected as the cooking course, and FIG. 8B is an example of a standby screen when “silver shari” is selected as the cooking course. is there.

  In the initial setting mode of the present embodiment, “Eco-cooked rice” and “Gin Shari” as the course options are cooking that selects whether to give priority to low power consumption or taste in cooking rice cooking. In one of the courses, when "Eco-cooked rice" is selected, the heating operation is performed with priority given to reducing power consumption as much as possible, and when "Silver Shari" is selected, priority is given to improving the taste as much as possible. Heating operation to cook. There are other course options for cooking courses, such as “Katasa cooking”, “Akitamachi”, “Koshihikari”, “Hitomebore”, which have options such as “Normal”, “Kai” and “Soft”. There are "brand cooking" with options such as, and these are combined to determine the final cooking course. For example, cooking is performed on a cooking course that combines options from each series of “silver shari”, “soft”, and “Akitakomachi”. In this embodiment, in the initial setting mode, the course options are only for “eco-cooking” and “silver shari”, but in this case, another course such as “Katasa cooking” or “Brand cooking” If there is a change, the options are set for each cooking, and the options for “eco-cooking rice” and “silver shari” are based on the selection result set in the initial setting mode.

  In other words, whether to cook with “eco-cooked rice” that reduces power consumption or “silver shari” that prioritizes the taste even if there is a little power consumption depends on the user's preference, and generally the user's policy does not change As long as it is an option that is always supposed to select one, if it is selected in advance in the initial setting mode, then it is possible to cook while selecting only other options without worrying.

  And in standby mode, the control part 12 will start the heat cooking corresponding to the cooking course currently selected, if the input from the rice cooking switch 11f is detected.

  In the standby mode, before operating the rice cooking switch 11f, the rice switch 11g is operated to select the type of rice to be cooked, or the cooking method switch 11h is operated to determine how to cook, for example, “ Conditions other than the cooking course selected in the initial setting mode can be set by selecting “normal”, “hard”, “soft”, or the like. For example, the cooking course can be selected in detail, for example, “Gin Shari”, the type of rice “Koshihikari”, and the cooking method “Kake”. At this time, “Silver Shari” of the cooking course has already been selected in the initial setting mode, so there is no need to select it again.

Here, the case where there is no initial setting mode is considered. The cooking courses “eco-cooking rice” and “silver shari” are usually not changed frequently because they depend on the user's preference whether to give priority to eco or taste. For example, if the cooking device is set so that “eco-cooked rice” is displayed as an option first, it will be cooked on the cooking course of “eco-cooked” unless the user performs an operation to select “silver shari”. The user may be discouraged if the taste is not so good. In recent cooking devices, especially rice cookers, there are a wide variety of menu and course options, and it is possible that the user may not be able to select all the options. For this reason, even if the taste is not good as described above, there are too many options displayed on the display unit 10, so it may not be noticed at first glance that “eco-cooking” is selected. It is difficult to understand that there is a “silver shari” that prioritizes the taste in the choices of the user, so even if the user does not taste very good, it is always “ There is a risk of cooking with "eco-cooking rice". Therefore, by providing the initial setting mode, when the power is turned on, the initial setting mode can be entered and a part of the cooking course can be forcibly selected. It is possible to prevent the user from being continuously cooked in a cooking course different from the user's preference.

  If the user who has selected “Eco-cooked rice” is a visitor and wants to cook temporarily on the “Silver Shari” cooking course, for example, by operating the cooking method switch 11h, the choice of hardness After that, options such as “eco-cooking” and “silver shari” selected in the initial setting mode appear, and all cooking courses can be selected regardless of the selection of the initial setting mode.

  In addition, when the enter / function switch 11a is operated in the standby mode, an option for shifting to the initial setting mode is prepared, and it is possible to shift to the initial setting mode again from there. At that time, the cooking course selected in the initial setting mode is stored again, and is reflected in the selection of the cooking course in the standby mode thereafter.

  In addition, the course options to be selected in the initial setting mode are not limited to “eco-cooking” and “silver shari”, but may be other series options such as “securate cooking”, and course options that change frequently. It is more preferable to select a course option that does not change much after it has been selected.

  Moreover, you may make it select the choice of not only one series but two or more series, for example, after selecting either "Eco-cooked rice" or "Ginshari", select the option of "Brand cooking" If the two series of course options are stored and the mode is shifted to the standby mode, the selection operation in the standby mode can be further simplified.

  Further, as another course option that can be selected in the standby mode, for example, a “care” option is also prepared. The “care” course is a non-cooking course different from other cooking courses, and is not a course for cooking, but a course for removing odor components and the like attached to a heating cooker by repeating cooking. The course options in the initial setting mode do not include the non-cooking course. That is, a non-cooking course such as a “care” course is a course option that is not selected when the user first uses the cooking device, and thus should not be a course option in the initial setting mode.

  With the above configuration, when the user first connects the heating cooker to the commercial power source to use the cooking device, the mode is switched to the initial setting mode, and the cooking course must be selected before starting cooking. Can be forced to do. In addition, when the power supply from the commercial power supply is detected after the initial setting mode is finished, the initial setting mode is not entered, so it is easy to use the favorite or usual cooking menu selected in the initial setting mode. Cooking can begin.

  In this embodiment, the end of the initial setting mode is determined by the determination / function switch 11a. However, for example, when the course option of the cooking course can be selected by directly touching with a touch panel or the like, the determination / function switch 11a is selected. Even if the operation is not performed, the number of operations can be reduced if the initial setting mode is terminated simultaneously with the selection of the cooking course.

  In this embodiment, only when power from the commercial power source is supplied for the first time, the mode is shifted to the initial setting mode. After the initial setting mode is finished, the initial setting mode is set when the commercial power is turned on next time. However, if the power is switched from the state in which the commercial power supply is not supplied to the initial setting mode, the initial setting mode is entered each time the commercial power is turned on. However, in the case of a cooking device that is installed and used in the same place, there are many cases where it is always connected to a commercial power supply. become. In addition, when there is no non-volatile memory and the backup power supply 13 is not provided or has a very small capacity, the initial setting mode is set whenever power from the commercial power supply is supplied. Since it is in a state where there is no memory of the end, since it shifts to the initial setting mode every time the power is turned on, it is not necessary to store the fact that the initial setting mode has ended.

  Moreover, although the control part 12 memorize | stored that the initial setting mode was complete | finished, you may make it erase | store a memory | storage, for example, when cooking is not carried out for a predetermined period, or when the electric power supply from a commercial power source is not carried out for a predetermined period. Thereby, it is possible to execute the initial setting mode again in response to a change on the user side that occurs while cooking is not performed for a long time. Examples of changes on the user's side are, for example, that the user changes due to the transfer of a heating cooker, the user's favorite tendency changes, the state of the cook changes as the season changes, etc. .

  As described above, the heating cooker according to the present invention enables the user to reliably set the optimal cooking course for the cooked food, and can provide the optimum cooking for the user or the cooked food. Therefore, the present invention can be applied to setting items for changing the setting of cooking.
