Embodiments for Carrying Out the Invention

[0011] 〔Embodiment 1〕 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the lid of the cooking appliance according to an embodiment of the present invention in a closed state. FIG. 2 is a perspective view of the lid of the cooking appliance shown in FIG. 1 in an open state.

[0012] (Overview of the cooking appliance) As shown in FIGS. 1 and 2, the cooking appliance 1 includes a cooker main body 11, a lid 12, and an inner pot 13.

[0013] (Cooker main body part) The cooker main body 11 includes an inner pot housing part 21, a heating part 22, a temperature sensor 23, and a weight sensor 24 (FIG. 3).

[0014] The inner pot accommodating part 21 is a recess formed in the cooker main body 11 and accommodates the inner pot 13. The heating part 22 heats the inner pot 13, that is, the food materials, accommodated in the inner pot accommodating part 21. The heating part 22 is, for example, composed of an induction heating coil, but is not limited thereto, and conventional well-known heating means can be used. The temperature sensor 23 detects the temperature of the inner pot 13. The weight sensor 24 detects the weight of the food materials accommodated in the inner pot 13.

[0015] (Lid body) The lid body (lid) 12 is attached to the cooker main body 11 so as to be openable and closable, and opens and closes the opening of the inner pot 13 stored in the cooker main body 11. The lid body 12 includes an outer lid 31, an inner lid 32, and a stirring mechanism 33.

[0016] The outer lid 31 is connected to the cooker main body 11 via a hinge spring 31a. The inner lid 32 is detachably attached to the outer lid 31 and closes the inner pot 13 in the closed state of the lid body 12.

[0017] Inside the outer lid 31, a control part (cooking control part, function control part) 34, a motor 35, and a speaker 36 are provided.

[0018] The control part 34 is composed of a CPU and controls various operations in the heating cooker 1, particularly the operation of heating and cooking the food materials. The control part 34 controls the heating part 22, the stirring mechanism 33, etc. based on the programs and input data stored in the ROM (Read Only Memory), and causes the heating cooker 1 to execute cooking according to the selected dish. Note that the arrangement location of the control part 34 is not particularly limited, and for example, it may be arranged in the cooker main body 11. The motor 35 rotates the stirring mechanism 33. The speaker 36 outputs a voice for notifying the user of information.

[0019] On the upper surface of the outer lid 31, an operation display unit 37 for operation and display is provided. The operation display unit 37 has a display unit 371 and various operation buttons 372 around the display unit 371. The operation buttons 372 include various selection buttons, a start / decision button, and a cancel button, as well as various buttons for instructing various operations to the heating cooker 1. The start / decision button is an operation button for instructing the start of cooking including reserved cooking.

[0020] The display unit 371 displays various information selected by the user according to the user's operations on the operation buttons 372 and the like.

[0021] (Stirring mechanism) The stirring mechanism 33 is driven by a motor 35 to rotate and appropriately stir the food in the inner pot 13 during cooking. The stirring mechanism 33 is detachably attached to the facing surface side of the inner lid 32 with respect to the inner pot 13 and has two stirring arms 331 and a rotating body 332. The stirring arms 331 are attached to the rotating body 332 and are in a lying state (solid line) when the stirring mechanism 33 is not in use and in an upright state (two-dot chain line) when the stirring mechanism 33 is in use.

[0022] (Inner pot 13) The inner pot 13 is arranged in the inner pot accommodating portion 21 of the cooker main body 11. The inner pot 13 accommodates food ingredients (such as vegetables, meat, fish, seasonings, etc.) to be cooked according to the type of dish. The inner pot 13 is formed of a high heat conductive member such as aluminum, for example.

[0023] (Control device of the heating cooker) Figure 3 is a block diagram showing the configuration of the control device of the heating cooker 1. As shown in Figure 3, the control device of the heating cooker 1 includes a control unit 34, and the control unit 34 is connected to a heating unit 22, a temperature sensor 23, a weight sensor 24, a motor drive circuit 38, a speaker drive circuit 39, an operation display unit 37, a timing unit 40, a lid opening / closing sensor (opening / closing detection unit) 41, and a storage unit 42.

[0024] The motor drive circuit 38 is controlled by the control unit 34 to drive the motor 35, and the speaker drive circuit 39 is controlled by the control unit 34 to drive the speaker 36. The timing unit 40 has a timer function and measures time.

[0025] The lid opening / closing sensor 41 is a sensor that detects the opening and closing of the outer lid 31, and sends the detected signal to the control unit 34. The control unit 34 controls the heating unit 22 to perform heat cooking according to the opening and closing of the outer lid 31. Details of the heat cooking control will be described later.

[0026] The storage unit 42 stores information on the control contents that the control unit 34 performs on the heating unit 22, the stirring mechanism 33, etc. for cooking each dish. In particular, the heating cooker 1 can automatically perform cooking for a number of dishes from the start to the end of cooking by reservation cooking. Therefore, the storage unit 42 stores information on the control contents (hereinafter referred to as reservation cooking information) that the control unit 34 performs on the heating unit 22, the stirring mechanism 33, etc. from the start to the completion of cooking for each dish in reservation cooking. In addition, the storage unit 42 stores information on the control contents (hereinafter referred to as normal cooking information) that the control unit 34 performs on the heating unit 22, the stirring mechanism 33, etc. from the start to the completion of cooking for each dish in normal cooking that is not reservation cooking. Note that the normal cooking information includes a cooking menu including the opening and closing state of the outer lid 31, that is, a cooking menu including a step of heating with the outer lid 31 closed and a step of heating with the outer lid 31 open from the start to the end of cooking.

[0027] In addition, the storage unit 42 stores various setting information by the operation button 372 and speech information indicating the content to be spoken by the speaker 36 during cooking and the like.

[0028] The control unit 34 controls the operations of the heating unit 22, the motor drive circuit 38 that drives the motor 35, and the speaker drive circuit 39 that drives the speaker 36 according to the control contents stored in the storage unit 42.

[0029] Specifically, the control unit 34 controls each unit to execute cooking based on the cooking information (reservation cooking information, normal cooking information) stored in the storage unit 42. In this case, the control unit 34 controls the operation of the heating unit 22 so that the temperature of the food ingredients becomes a predetermined temperature specified in the cooking information.

[0030] The control unit 34 indirectly detects the temperature of the food ingredients in the inner pot 13 based on the temperature of the inner pot 13 detected by the temperature sensor 23, the weight of the food ingredients detected by the weight sensor 24, and the heating time by the heating unit 22.

[0031] That is, the heating cooker 1 stores in the storage unit 42 data associating the temperature detected by the temperature sensor 23, the weight of the food ingredients, and the heating time with the temperature of the food ingredients. The control unit 34 refers to the above data and detects the temperature of the food ingredients in the inner pot 13 from the temperature detected by the temperature sensor 23, the weight of the food ingredients, and the heating time.

[0032] (Heating Cooking Control) When the heating cooker 1 detects that the lid is closed by the lid opening / closing sensor 41, it executes a first heating cooking process for performing heating cooking with the lid closed, and when it detects that the lid is opened by the lid opening / closing sensor 41, it performs heating cooking control so as to execute a second heating cooking process for performing heating cooking with the lid open.

[0033] Specifically, the heating cooker 1 can perform heating cooking in both a state where the outer lid 31 is closed and a state where the outer lid 31 is open for one cooking menu. That is, the heating cooker 1 can execute a cooking menu including a step of heating with the outer lid 31 closed (first heating cooking step), a step of heating with the outer lid 31 open (second heating cooking step), and a step of heating with the outer lid 31 closed (third heating cooking step) from the start to the end of cooking. When such a cooking menu is executed, for example, the heating cooking control as shown in FIG. 4 is obtained. In the following description of the heating cooking control, the lid includes the outer lid 31 and the inner lid 32. That is, opening the lid means opening the outer lid 31 and the inner lid 32, and closing the lid means closing the outer lid 31 and the inner lid 32.

[0034] The cooking control shown in FIG. 4 shows an example in which a first cooking step of cooking with the lid closed at the start of cooking is executed, and after a predetermined time has elapsed, a second cooking step or a third cooking step of cooking with the lid open until the end of cooking is executed.

[0035] That is, when the cooking menu selected by the user is executed, first, the first cooking step is executed (step S11). When the heating time predetermined by the first cooking step has elapsed, the heating is terminated, so it is determined whether or not the heating has ended (step S12).

[0036] If it is determined that the heating in the first cooking step has ended, the user is notified that the first cooking step has ended (step S13). Here, a sound, voice, etc. for notifying that the first cooking step has ended is emitted from the speaker (notification unit) 36 built in the cooking appliance 1. As a method of notifying the user, in addition to sound and voice, a display indicating that the first cooking step has ended may be performed on the display unit 371 of the operation display unit 37, or sound and display may be combined.

[0037] Subsequently, it is determined whether or not the lid has been opened (step S14). Specifically, the opening and closing of the lid is determined based on the detection signal of the lid open / close sensor 41. Here, if it is determined that the lid has been opened, a second cooking step of cooking with the lid open is executed (step 15). When the heating time predetermined by the second cooking step has elapsed, the heating is terminated, so it is determined whether or not the heating has ended (step S16). If it is determined that the heating in the second cooking step has ended, the cooking is terminated.

[0038] On the one hand, in step S14, if the lid is not opened, it is determined whether a predetermined time has elapsed (step S17). Here, if it is determined that the predetermined time has elapsed, it is determined that there is no user near the cooking appliance 1, and the process proceeds to step S18, where a third cooking process is executed instead of the second cooking process (step S18). Here, in the third cooking process, when restarting the cooking, cooking is performed at a heating temperature and a heating time different from the heating temperature and the heating time of the cooking performed in the second cooking process. For example, in the third cooking process, since cooking is performed with the lid closed, the heating temperature is set lower than the heating temperature in the second cooking process, and the heating time is set shorter than the heating time in the second cooking process. Also, in the third cooking process, since cooking is performed with the lid closed, the heating temperature may be lower than the heating temperature in the second cooking process, or the heating time may be shorter than the heating time in the second cooking process. Thereby, it is possible to approach the cooking state of the second cooking process in which cooking is performed with the lid open.

[0039] Thereafter, when the predetermined heating time elapses by the third cooking process, the heating is terminated, so it is determined whether the heating has ended (step S19). If it is determined that the heating in the third cooking process has ended, the cooking is terminated. Here, the heating time of the third cooking process may be the same as the heating time of the second cooking process, or a heating time different from the heating time of the second cooking process may be set in advance.

[0040] The cooking control shown in FIG. 4 is described assuming that the lid is kept open while the second cooking process is being executed.

[0041] The cooking control shown in FIG. 5 shows how the cooking control is performed when the lid is closed during the execution of the second cooking process.

[0042] That is, during the execution of the second cooking process (step S21), it is determined whether the lid is closed (step 22). Here, if the lid is not closed (No), when the heating time predetermined by the second cooking process has elapsed, the heating is terminated, so it is determined whether the heating has ended (step S23). If it is determined that the heating in the second cooking process has ended, the cooking is terminated.

[0043] On the other hand, in step S22, if it is determined that the lid is closed (Yes), the heating is stopped (step S24), and the user is notified that the heating has been stopped (step S25). Subsequently, it is determined whether the lid has been opened (step S26). If it is determined that the lid has been opened, the heating is restarted (step S27), and the process proceeds to step S22 to determine whether the lid is closed.

[0044] (Effect) As described above, the cooker 1 configured as described above can perform various cooking menus because cooking can be performed not only with the lid closed but also with the lid open.

[0045] By the way, when the second cooking process, which is cooking with the lid open, is executed in the cooker 1, the user automatically performs heating control so that there is no particular need to operate the cooker 1. However, in some cases, it becomes necessary to operate the cooker 1. In such a case, as shown in FIG. 2, if the outer lid 31 is open, the operation display unit 37 provided on the outer lid 31 will be operated. However, since the operation display unit 37 is located at a position via the cooker main body 11 from the user, there arises a problem that the operation is difficult.

[0046] Therefore, when the second cooking process is executed, the outer lid 31 may be completely removed from the cooker main body 11, and the operation display unit 37 provided on the removed outer lid 31 may be operated.

[0047] Alternatively, by providing an operation display unit on the cooker main body 11 side, even when the outer lid 31 is open, it may be made easier for the user to operate.

[0048] In the following Embodiment 2, an example in which an operation display unit is provided on the side of the cooking device main body 11 will be described.

[0049] 〔Embodiment 2〕 Hereinafter, an embodiment of the present invention will be described in detail. For the sake of convenience of explanation, members having the same functions as the members described in the above embodiment are denoted by the same reference numerals, and the description thereof will not be repeated.

[0050] (Overview of the cooking device) As shown in FIGS. 6 and 7, the cooking device 1A includes a cooking device main body 11, a lid body 12, and an inner pot 13, similarly to the cooking device 1 of the first embodiment. The difference from the cooking device 1 of the first embodiment is that an operation display unit (main body side operation display unit 43) for operating the cooking device 1A is also provided on the cooking device main body 11. In this embodiment, it is described that the main body side operation display unit 43 and the operation display unit 37 provided on the outer lid 31 have the same functions.

[0051] (Control device of the cooking device) FIG. 8 is a block diagram showing the configuration of the control device of the cooking device 1. As shown in FIG. 8, the control device of the cooking device 1A includes a control unit 34, and the control unit 34 is connected to a heating unit 22, a temperature sensor 23, a weight sensor 24, a motor drive circuit 38, a speaker drive circuit 39, an operation display unit 37, a timing unit 40, a lid opening / closing sensor 41, a storage unit 42, and a main body side operation display unit 43.

[0052] As shown in FIG. 7, the main body side operation display unit 43 is provided on the front side of the cooking device main body 11, that is, on the side facing the hinge portion of the outer lid 31. The main body side operation display unit 43 is composed of a touch panel type liquid crystal display unit, and can switch between a first display (full display) that displays all operation keys so that all functions of the cooking device 1A can be operated, and a second display (simple display) that displays only a part of the functions of the cooking device 1A by narrowing down the operation keys as needed.

[0053] In the full display on the main body side operation display unit 43, for example, as shown in Fig. 9(a), various operation buttons 432 are displayed around the display unit 431. The operation buttons 432 include various selection buttons, start / decision buttons, and cancel buttons, as well as various buttons for instructing various operations to the cooking heater 1. The full display on the main body side operation display unit 43 may set the operation buttons 432 so as to execute the same functions as those of the operation display unit 37 provided on the outer lid 31, or may set the operation buttons 432 so as to execute functions more limited than those of the operation display unit 37, or may set the operation buttons 432 so as to execute more functions than those of the operation display unit 37.

[0054] On the other hand, in the simple display on the main body side operation display unit 43, for example, as shown in Fig. 9(b), around the display unit 431, there are operation buttons 432 for the temperature adjustment key and the cancel key. Thus, in the simple display, the functions that can be operated are limited.

[0055] Here, the switching control between the first display (full display) and the second display (simple display) on the main body side operation display unit 43 will be described below.

[0056] (Display control) Fig. 10 shows the flow of the process of the switching control between the first display (full display) and the second display (simple display) on the main body side operation display unit 43. Here, an example will be described in which, among the cooking menus, first, cooking is performed with the outer lid 31 closed, and after a predetermined time has elapsed, cooking is performed with the outer lid 31 open.

[0057] First, when the main body side operation display unit 43 is in the full display state shown in Fig. 9(a) (step S31), it is determined whether the outer lid 31 is open (step S32). Here, the lid opening / closing sensor 41 detects that the outer lid 31 is open and sends the detected signal to the control unit 34.

[0058] Next, in step S32, if it is determined that the outer lid 31 is opened, simple display is executed (step S33). Here, the control unit 34 receives a detection signal indicating that the outer lid 31 is opened from the lid opening / closing sensor 41, and causes the main body side operation display unit 43 to perform the simple display shown in Fig. 9(b).

[0059] Subsequently, it is determined whether or not the outer lid 31 is closed (step S34). If it is determined that the outer lid 31 is closed, the process proceeds to step S31, and full display is performed again. Here, the control unit 34 receives a detection signal indicating that the outer lid 31 is closed from the lid opening / closing sensor 41, and causes the main body side operation display unit 43 to perform the full display shown in Fig. 9(a) again.

[0060] (Effect) In this way, by switching the display of the main body side operation display unit 43 in conjunction with the opening and closing of the outer lid 31, the operability of the user can be improved when cooking is executed in conjunction with the opening and closing of the outer lid 31. For example, during a cooking process (second heating cooking process) executed with the outer lid 31 open, usually, operations such as temperature setting and cancellation are sufficient. Therefore, if other than these operation keys are displayed, the user may get lost in the operations. However, as described above, if only the necessary operation keys are displayed, the user will not get lost in the operations even when looking at the main body side operation display unit 43.

[0061] Note that in the present embodiment, the full display of the main body side operation display unit 43 is performed with the outer lid 31 closed, but it is not limited thereto. Even when the outer lid 31 is open, the main body side operation display unit 43 may be in full display. In particular, in the case where two operation display units, i.e., the operation display unit 37 of the outer lid 31 and the main body side operation display unit 43 of the cooker main body 11, are provided as in the heating cooker 1A, when the outer lid 31 is open, the operation display unit 37 is in a position that is difficult for the user to operate. Therefore, if the main body side operation display unit 43 of the cooker main body 11 is in full display, the user can perform various operations.

[0062] Also, when two operation display units are provided as in the cooking device 1A, the user may be confused about which operation display unit to operate. In particular, when the outer lid 31 is closed, both of the two operation display units are in positions that are easy for the user to operate, so the user is likely to be confused about which operation display unit to operate. Therefore, when the outer lid 31 is closed, only the operation of the operation display unit 37 provided on the outer lid 31 may be accepted, and the operation of the main body side operation display unit 43 provided on the cooking device main body 11 may not be accepted. When the outer lid 31 is open, the operation of the operation display unit 37 provided on the outer lid 31 may not be accepted, and only the operation of the main body side operation display unit 43 provided on the cooking device main body 11 may be accepted. Thereby, the user can easily determine which operation unit should be operated, so there is no fear of being confused about the operation display unit to be operated.

[0063] Furthermore, when the outer lid 31 is open, if the operation of the operation display unit 37 provided on the outer lid 31 is not accepted and only the operation of the main body side operation display unit 43 provided on the cooking device main body 11 is accepted, the display of the main body side operation display unit 43 may be a full display as shown in Fig. 9(a) or a simple display as shown in Fig. 9(b).

[0064] 〔Embodiment 3〕 Hereinafter, an embodiment of the present invention will be described in detail. For the sake of convenience of explanation, members having the same functions as those described in the above Embodiments 1 and 2 are denoted by the same reference numerals, and the description thereof will not be repeated.

[0065] The cooking device according to the present embodiment has substantially the same configuration as the cooking device 1A of the above Embodiment 2, and is different in that only one of the two operation display units (operation display unit 37, main body side operation display unit 43) is provided. Similar to Embodiment 2, the display of the operation display unit is switched between a full display and a simple display in conjunction with the opening and closing of the outer lid 31.

[0066] For example, in the case where the operation display unit 37 is provided only on the outer lid 31 side as in the cooking appliance 1 shown in FIG. 1, when the outer lid 31 is closed, the operation display unit 37 performs full display as shown in FIG. 9(a), and when the outer lid 31 is open, the operation display unit 37 performs simple display as shown in FIG. 9(b). Note that the state where the outer lid 31 is open includes the state where the outer lid 31 is connected to the main body 11 of the cooking appliance by a hinge as shown in FIG. 2 and the state where the outer lid 31 is completely removed from the main body 11 of the cooking appliance (not shown). In the state where the outer lid 31 is connected to the main body 11 of the cooking appliance by a hinge, even if the outer lid 31 is opened and the operation display unit 37 performs simple display, it is difficult to operate, but in the state where the outer lid 31 is completely removed from the main body 11 of the cooking appliance, even if the outer lid 31 is opened and the operation display unit 37 performs simple display, it is easy to operate.

[0067] Also, when the operation display unit 37 is not provided on the outer lid 31 and only the main body side operation display unit 43 is provided on the main body 11 of the cooking appliance, as described above, when the outer lid 31 is closed, the main body side operation display unit 43 performs full display as shown in FIG. 9(a), and when the outer lid 31 is open, the main body side operation display unit 43 performs simple display as shown in FIG. 9(b).

[0068] Note that the full display and simple display shown in FIGS. 9(a) and 9(b) are examples and are not limited to these examples. Also, these display examples may be obtained by downloading from a server or the like on the Internet via a communication network.

[0069] 〔Example of Realization by Software〕 The control block (particularly the control unit 34) of the cooking appliances 1 and 1A may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or may be realized by software.

[0070] In the latter case, the cooking heaters 1 and 1A include a computer that executes instructions of a program which is software for realizing each function. This computer includes, for example, at least one processor (control device) and at least one computer-readable recording medium that stores the above program. Then, in the above computer, when the above processor reads and executes the above program from the above recording medium, the object of the present invention is achieved. As the above processor, for example, a CPU (Central Processing Unit) can be used. As the above recording medium, in addition to a "non-transitory tangible medium" such as a ROM (Read Only Memory), a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, etc. can be used. Further, it may further include a RAM (Random Access Memory) for expanding the above program. Further, the above program may be supplied to the above computer via any transmission medium (communication network, broadcast wave, etc.) capable of transmitting the program. Note that one aspect of the present invention can also be realized in the form of a data signal embedded in a carrier wave in which the above program is embodied by electronic transmission.

[0071] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. Further, by combining the technical means disclosed in each embodiment, new technical features can be formed.
