[0014] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the present disclosure, there was a technology in a cooking device that heats an object to be heated in a shorter time by heating it at a higher output than the heating conditions input by the user. However, the conventional technology requires an operation such as switching between heating according to the heating conditions or at a higher output than the heating conditions, and the inventors discovered a problem that there is a demand for a simpler operation, and in order to solve this problem, they have come to constitute the subject of the present disclosure. Therefore, the present disclosure provides a heating device, a control method for a heating device, and a program that can improve user convenience regarding heat cooking.

[0015] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanations than necessary may be omitted. For example, detailed explanations of already well-known matters or duplicate explanations of substantially the same configurations may be omitted. It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0016] (Embodiment 1) [1-1. Configuration] [1-1-1. Configuration of heating device] Fig. 1 is a perspective view of a heating device 1 in embodiment 1. The heating device 1 shown in Fig. 1 has a box-shaped cabinet 2. In Fig. 1 and Fig. 2 described later, arrows indicate directions corresponding to the cabinet 2 in an installed state of the heating device 1. The symbol UP indicates the upward direction, the symbol DW indicates the downward direction, the symbol FR indicates the forward direction, the symbol RE indicates the rearward direction, the symbol R indicates the rightward direction, and the symbol L indicates the leftward direction.

[0017] A door 4 is provided on the front of the cabinet 2 so as to be able to open and close, and when the door 4 is opened, a heating chamber 7 provided inside the cabinet 2 is exposed. The heating chamber 7 contains an object to be heated by the heating device 1. The heating device 1 is a cooking appliance that heats and cooks the object to be heated by irradiating microwaves to the object to be heated contained in the heating chamber 7. The object to be heated in this embodiment is food.

[0018] An operation panel 3 is disposed on the front surface of the cabinet 2 so as to be aligned with the door 4. The operation panel 3 may be disposed in front of the door 4. The operation panel 3 includes switches and the like that accept operations by a user, as will be described later.

[0019] The heating device 1 heats the object to be heated housed in the heating chamber 7 by a microwave oven function using microwaves. The heating device 1 described in this embodiment also has an oven function and a grill function that heat the object to be heated by a graphite heater or the like, but these functions are not essential to the configuration of the present disclosure.

[0020] [1-1-2. Configuration of the operation section] FIG. 2 is a front view of operation panel 3 in the first embodiment. The operation panel 3 includes a first operation unit 30, a dial 39, and a second operation unit 40. The first operation unit 30, the dial 39, and the second operation unit 40 configure an operation unit 3A.

[0021] The first operation unit 30 has a plurality of key operation units including a microwave heating command key 31, a cancel key 32, and a start key 33. The second operation unit 40 has a short-time heating key 41 as a key operation unit. These key operation units are operators as operation objects operated by the user, and accept at least one of a touch operation and a pressing operation by the user.

[0022] Microwave heating command key 31, cancel key 32, and start key 33 may be switches attached to the surface of operation panel 3, or may be switches embedded on the back side of a flexible surface panel that constitutes the surface of operation panel 3. Microwave heating command key 31, cancel key 32, and start key 33 may also be provided on the surface panel of operation panel 3 and comprise one or more contact sensors that detect a touch operation by the user. Specifically, microwave heating command key 31, cancel key 32, and start key 33 may each be associated with an operation position of a touch operation detected by a contact sensor.

[0023] The microwave heating command key 31 is a key operation unit that instructs the selection of a microwave function from among multiple functions such as a microwave function, an oven function, and a grill function that the heating device 1 has. The cancel key 32 is a key operation unit that instructs the cancellation of the contents instructed by the operation of the microwave heating command key 31, the start key 33, and the dial 39. The start key 33 is a key operation unit that determines the contents instructed by the operation of the microwave heating command key 31 and the dial 39, and instructs an operation according to the determined contents.

[0024] The heating device 1 is capable of switching between a plurality of outputs in the microwave oven function. The output of the heating device 1 is, for example, the output value of the microwave, and in this embodiment, an example is given in which the output can be switched between six levels of 150W (watts), 300W, 500W, 600W, 800W, and 1000W. These six levels of output are the output of the heating unit 60, which will be described later, and the switchable output may be limited by a user's operation. This is just one example, and there is no limit to the output of the heating device 1 to which the present disclosure is applied.

[0025] The first operation of the microwave heating command key 31 is an instruction to select the microwave function. The operation of the microwave heating command key 31 within a predetermined time from the first operation of the microwave heating command key 31 is an operation to instruct switching of the output of the microwave function. For example, in response to the first operation of the microwave heating command key 31, the initial value of 600W is selected as the output of the microwave function of the heating device 1. The second and subsequent operations of the microwave heating command key 31 are operations to instruct switching of the output of the microwave function of the heating device 1 in sequence. In this embodiment, the output is switched in the order of 600W-500W-300W-150W-800W-600W, and if the operation is performed more than once, the output is switched in a cyclical manner in the above order. Of course, it is also possible to configure the output to be switched in another order.

[0026] The heating device 1 of this embodiment limits the output selectable by user operation to an output other than 1000W. As described later, an upper limit is set for the time during which the heating unit 60 can continuously output microwaves at 1000W. By restricting the user from manually selecting 1000W, there is an advantage that the user will not feel dissatisfied due to the upper limit on the output time. After an output has been selected by operating the microwave heating command key 31 once or multiple times, when the start key 33 is operated, the output of the microwave oven function is determined.

[0027] In addition, the first operation unit 30 may include other key operation units, such as a key operation unit that accepts operations related to the oven function and grill function of the heating device 1, and a key operation unit that accepts operations related to an automatic heating function that heats the object to be heated according to a predetermined program.

[0028] The dial 39 is an operation unit that accepts a rotation operation. The operation of rotating the dial 39 is, for example, an operation of inputting a numerical value. Specifically, the numerical value can be increased by rotating the dial 39 in a clockwise (CW) direction, and decreased by rotating the dial 39 in a counterclockwise (CCW) direction. The numerical value input by the dial 39 is, for example, the time for heating by the microwave function, that is, the heating time. When the start key 33 is operated in a state where a specific numerical value is determined by the rotation operation of the dial 39, the heating time input by the dial 39 is determined. In addition, the dial 39 may be capable of executing an operation to instruct switching of the output in the microwave function. For example, in a state where an initial value of 600 W is selected as the output of the heating device 1, the output may be switched to 800 W by rotating the dial 39 clockwise, and the output may be switched to 500 W, 300 W, and 150 W in that order by rotating the dial 39 counterclockwise. The switching of the output by the operation of the dial 39 may not be cyclic.

[0029] In this manner, heating conditions including the output of the microwave oven function and the heating time are input using microwave heating command key 31, start key 33, and dial 39. When start key 33 is operated after the heating conditions have been input, heating device 1 heats the object to be heated in accordance with the heating conditions.

[0030] The short-time heating key 41 is a dedicated key operation unit for instructing short-time heating when the heating device 1 performs microwave cooking. Short-time heating includes heating at a higher output than the heating conditions input by operating the microwave heating instruction key 31, start key 33, and dial 39, and is an operation that ends the heating in a shorter time than the heating conditions. Short-time heating is an example of "high-output heating." When the microwave function is selected and the short-time heating key 41 is not operated, the heating device 1 performs heating according to the heating conditions, and when the short-time heating key 41 is operated, it performs short-time heating. The short-time heating key 41 corresponds to an example of a "high-output operation unit."

[0031] In cooking instructions, cooking recipes, and other cooking instructions for various foods including processed foods, there are many descriptions that specify the microwave output and heating time. It is assumed that a user who uses the heating device 1 according to these descriptions will input the output and heating time written in the instructions using the microwave heating instruction key 31 and dial 39. On the other hand, if the heating device 1 has a function of heating at high output, the required heating can be completed in a shorter time by heating the object to be heated at a higher output than the output described in the instructions. However, in order to perform heating equivalent to the output and heating time described in various instructions at a higher output, it is necessary to determine the output and heating time taking into account the required amount of heat. It is a heavy burden and not easy for the user to make such a judgment by himself. The heating device 1 of this embodiment can perform short-time heating by operating the short-time heating key 41 after the user inputs the heating conditions. In short-time heating, the heating device 1 performs heating that matches the input heating conditions using a higher output. This allows the user to perform the required heating in a shorter time in a method that is easy for the user to perform, thereby improving the user's convenience.

[0032] The display unit 50 has a display panel such as a liquid crystal display panel or an organic EL (Electro Luminescence) panel, and displays characters and symbols. In the example of Fig. 2, the display unit 50 displays a numerical value display section 51, a unit display 52, a start guide icon 53, and a short-time heating icon 54.

[0033] Numerical value display section 51 displays a multi-digit numerical value. For example, the output value selected by operating microwave heating command key 31, the heating time input by operating dial 39, and the remaining heating time during heating are displayed on numeric value display section 51. Unit display 52 displays the unit of the numerical value displayed on numeric display section 51. In this embodiment, unit display 52 can display "W" corresponding to the case where numeric display section 51 displays output, and "minutes" and "seconds" corresponding to the case where numeric display section 51 displays time.

[0034] The start guide icon 53 is an image or a symbol that guides the user to operate the start guide icon 53. The start guide icon 53 is displayed after the heating time is selected by the dial 39, for example. The short-time heating icon 54 is an image or symbol relating to short-time heating by the heating device 1. The short-time heating icon 54 is displayed, for example, when short-time heating can be performed by operating the short-time heating key 41 and while short-time heating is being performed. Displaying the short-time heating icon 54 by the display unit 50 is an example of notifying that short-time heating is possible, and the display unit 50 corresponds to an example of a "notification unit."

[0035] [1-1-3. Configuration of the heating device control system] FIG. 3 is a block diagram of the heating device 1 in the first embodiment. The heating device 1 includes a control unit 100 that controls each part of the heating device 1. The first operation unit 30, the dial 39, and the second operation unit 40 that constitute the operation unit 3A are connected to the control unit 100. When the first operation unit 30 receives an operation of the microwave heating instruction key 31, the cancel key 32, the start key 33, or any other key operation unit, it outputs an operation signal corresponding to the operated key operation unit to the control unit 100. The dial 39 outputs an operation signal indicating the rotation direction and rotation amount of the dial 39 to the control unit 100 in response to an operation of rotating the dial 39. When the second operation unit 40 receives an operation of the short-time heating key 41, it outputs an operation signal indicating the operation of the short-time heating key 41 to the control unit 100.

[0036] The control unit 100 is connected to the display unit 50, the heating unit 60, and the sound output unit 70. The heating unit 60 includes a magnetron 61 that outputs microwaves, a drive board 62 that supplies power to the magnetron 61 and controls the output, and a cooling fan 63 that cools the magnetron 61. The heating unit 60 may also include a waveguide and an antenna (not shown). The sound output unit 70 is a device that outputs an alarm sound, such as a buzzer or other speaker. The sound output unit 70 corresponds to an example of a "notification unit."

[0037] The control unit 100 includes a processor 110, a memory 120, and a non-volatile storage unit 130. The processor 110 is configured with a CPU (Central Processing Unit), an MPU (Micro Processing Unit), and the like. The memory 120 is a volatile storage device, and is configured with, for example, a RAM (Random Access Memory). The memory 120 forms a work area that temporarily stores programs and data executed by the processor 110. The non-volatile storage unit 130 is configured with, for example, a ROM (Read Only Memory) or a flash memory, and stores the programs executed by the processor 110 and the data processed by the processor 110 in a non-volatile manner.

[0038] For example, the non-volatile storage unit 130 stores a control program 131, setting data 132, and count data 133.

[0039] The processor 110 reads and executes the control program 131 to function as a reception unit 111, a display control unit 112, and a heating control unit 113.

[0040] The reception unit 111 receives, based on operation signals output by the first operation unit 30, the dial 39, and the second operation unit 40, operations performed by the user on the operation unit 3A. The display control unit 112 controls the display on the display unit 50 in accordance with the operation content accepted by the acceptance unit 111 and the control of the heating unit 60 executed by the heating control unit 113.

[0041] The heating control unit 113 controls the heating unit 60 based on the operation content received by the receiving unit 111 and the state of the heating unit 60. Specifically, the heating control unit 113 determines the microwave output from the magnetron 61 and the time for outputting the microwave, and controls the driving board 62 to cause the magnetron 61 to oscillate the microwave.

[0042] The heating control unit 113 manages the operating state of the magnetron 61 in order to protect the magnetron 61. Specifically, it limits the time during which the magnetron 61 continuously outputs high-power microwaves. To achieve this limitation, the heating control unit 113 stores a first counter 121 and a second counter 122 in the memory 120. The first counter 121 and the second counter 122 correspond to an example of "state data".

[0043] The first counter 121 and the second counter 122 are counters that count the time during which the magnetron 61 outputs microwaves at a predetermined output or higher. In this embodiment, an example in which two counters are formed in the memory 120 will be described, but this is just one example, and the number of counters is not limited.

[0044] An output power equal to or greater than a predetermined level is, for example, the default output value of the microwave oven function of the heating device 1, i.e., an output power exceeding 600 W. In this embodiment, it is 1000 W and 800 W. In the following description, as an example, there are two types of outputs of the magnetron 61 that are equal to or greater than a predetermined level. These two types of outputs are referred to as the first output and the second output. The first output is the highest output among the outputs used by the heating device 1 for heating, and is 1000 W in this embodiment. The second output is the next highest output after the first output among the outputs used by the heating device 1 for heating, and is 800 W in this embodiment.

[0045] The count value per second that the heating control unit 113 adds to the first counter 121 is defined as count value A, and the count value per second that the heating control unit 113 adds to the second counter 122 is defined as count value B. The count value A includes count value A1 and count value A2. The count value A1 is the count value per second that is added to the first counter 121 while the magnetron 61 outputs microwaves at 1000 W. The count value A2 is the count value per second that is added to the first counter 121 while the magnetron 61 outputs microwaves at 800 W.

[0046] The count value B includes a count value B1 and a count value B2. The count value B1 is a count value per second that is added to the second counter 122 while the magnetron 61 outputs microwaves at 1000 W. The count value B2 is a count value per second that is added to the second counter 122 while the magnetron 61 outputs microwaves at 800 W.

[0047] The count values ​​A1, A2, B1, and B2 may all be different values ​​from one another, or may include a common value. The specific values ​​of the count values ​​A1, A2, B1, and B2 are appropriately set based on the specifications of the magnetron 61. For example, the count value A1 can be 10, the count value A2 can be 16, the count value B1 can be 12, and the count value B2 can be 14.

[0048] An upper limit is set for each of the first counter 121 and the second counter 122. When the first counter 121 reaches the upper limit, the heating control unit 113 stops the output of 1000 W by the magnetron 61. Similarly, when the second counter 122 reaches the upper limit, the heating control unit 113 stops the output of 800 W by the magnetron 61. In other words, the count value of the first counter 121 limits the first main output by the magnetron 61, and the count value of the second counter 122 limits the second output by the magnetron 61. The upper limit values ​​of the first counter 121 and the second counter 122 may be a common value or different values. These specific values ​​are appropriately set based on the specifications of the magnetron 61, etc. For example, the upper limit value of the first counter 121 can be 1500, and the upper limit value of the second counter 122 can be 5000. As described above, when the first output is set to be greater than the second output, it is preferable that the upper limit value of the first counter 121 is equal to or smaller than the upper limit value of the second counter 122.

[0049] The heating control unit 113 subtracts the count values ​​of the first counter 121 and the second counter 122 while the magnetron 61 is not outputting microwaves. This corresponds to a decrease in the temperature of the magnetron 61 while the magnetron 61 is stopped. The subtraction values ​​per second by which the heating control unit 113 subtracts the first counter 121 and the second counter 122 may be a common value or different values. These specific values ​​are appropriately set based on the specifications of the magnetron 61, etc. For example, the subtraction value per second of the first counter 121 can be 10, and the subtraction value per second of the second counter 122 can be 10.

[0050] The count values ​​A1, A2, B1, B2, the upper limit and subtraction value of the first counter 121, and the upper limit and subtraction value of the second counter 122 are, for example, included in the setting data 132 and stored in the non-volatile storage unit 130. The heating control unit 113 performs processing related to the first counter 121 and the second counter 122 in accordance with the setting data 132. The difference between the count value and the upper limit of the first counter 121 corresponds to the time during which microwaves can be output at the first output, and indicates the time during which the first output can be output. The difference between the count value and the upper limit of the second counter 122 corresponds to the time during which microwaves can be output at the second output, and indicates the time during which the second output can be output.

[0051] Since the memory 120 is a volatile storage device, the count values ​​of the first counter 121 and the second counter 122 may be lost when the power supply of the heating device 1 is cut off. For example, when the power supply of the heating device 1 is turned on in a short time after the power supply is cut off, the count values ​​of the first counter 121 and the second counter 122 become 0 regardless of the temperature of the magnetron 61. In such a case, it is difficult to efficiently manage the magnetron 61. Therefore, in this embodiment, the heating control unit 113 stores the count values ​​of the first counter 121 and the second counter 122 as count data 133 in the nonvolatile storage unit 130 according to the operating state of the heating device 1. Specifically, the heating control unit 113 stores the count data 133 in the nonvolatile storage unit 130 when the heating device 1 stops heating and when the power supply of the heating device 1 is cut off. If the count data 133 is already stored in the nonvolatile storage unit 130, the heating control unit 113 updates the count data 133. When the count values ​​of the first counter 121 and the second counter 122 are lost, the heating control unit 113 sets the count values ​​of the first counter 121 and the second counter 122 based on the count data 133. This makes it possible to appropriately manage the state of the magnetron 61 even if the count values ​​of the first counter 121 and the second counter 122 are lost due to a power outage or the like. The count data 133 corresponds to an example of "state data".

[0052] The heating control unit 113 executes short-time heating in response to the operation of the short-time heating key 41. The short-time heating is an operation for operating the magnetron 61 at a higher output than the heating conditions input by the operation of the first operation unit 30 and the dial 39, and by performing short-time heating, the heating of the object to be heated can be completed in a time shorter than the heating conditions.

[0053] When short-time heating is performed, the heating control unit 113 determines the output of the magnetron 61 and the heating time when short-time heating is performed. At this time, the heating control unit 113 determines the output and the heating time so that the heat amount of short-time heating corresponds to the heat amount when the heating conditions input by the user are executed. The heat amount can be said to be energy given to the object to be heated in the heating chamber 7, and can be approximated by the energy of the microwaves output by the magnetron 61. In this embodiment, the energy of the microwaves output by the magnetron 61 is considered to be the heat amount. Specifically, the value obtained by multiplying the output of the magnetron 61 by the heating time is used as an index of the heat amount.

[0054] For example, when the heating conditions are 600 W and 5 minutes, the heating control unit 113 calculates the index value of the amount of heat by the following formula (1). 600[W]×300[seconds]=180000…(1)

[0055] Here, the heating amount when executing the heating conditions input by the user is called the designated heating amount. The heating amount of short-time heating is the heating amount corresponding to the designated heating amount. The corresponding heating amount means, for example, that the index value of the heating amount of short-time heating is the same as the index value of the designated heating amount, or that the index value of the heating amount of short-time heating is greater than the index value of the designated heating amount and the difference is within a preset range. Also, the corresponding heating amount may include that the index value of the heating amount of short-time heating is smaller than the index value of the designated heating amount and the difference is within a preset range.

[0056] The heating control unit 113 determines the output and heating time of the short-term heating so as to obtain a heating amount corresponding to the designated heating amount, including an output higher than the heating conditions. Hereinafter, a combination of the output and heating time in the short-term heating is referred to as a short-term heating condition.

[0057] For example, when the heating conditions are 600 W and 5 minutes, the heating control unit 113 generates a short-time heating condition including at least one of 800 W and 1000 W, and corresponding to an index value of 180,000.

[0058] The heating control unit 113 generates the short-time heating condition based on the amount of heat as well as the operation history of the magnetron 61. Specifically, the heating control unit 113 generates the short-time heating condition so that the count values ​​of the first counter 121 and the second counter 122 do not exceed their upper limit values. For example, when the heating condition is 600 W and 5 minutes, if an index value is set to 180000 using only an output of 1000 W, the heating time will be 180 seconds.

[0059] Here, when the count value of the first counter 121 exceeds the upper limit value after 180 seconds of heating, the heating control unit 113 generates a short-time heating condition including heating at a lower output in addition to heating at 1000 W. That is, the heating time of 1000 W is set to a time not exceeding the upper limit value, and heating at an output included in the input heating condition is performed. Here, the heating control unit 113 may preferentially adopt the input heating condition of 500 W. For example, the heating control unit 113 generates a short-time heating condition including heating at 1000 W for 2 minutes and heating at 500 W for 2 minutes in response to a heating condition of 600 W for 5 minutes. The index value of the heating amount of this short-time heating condition is calculated by the following formula (2). In this example, the period in which the output of 1000 W is performed corresponds to an example of the "first period", and the period in which the output of 500 W is performed corresponds to an example of the "second period". The first period may be a period in which a higher output than the heating condition is performed, for example, a period in which an output of 800 W or 600 W is performed. Furthermore, in the process of generating the short-time heating conditions, the heating control unit 113 may generate short-time heating conditions in which the heating time of 1000 W is set to a time not exceeding an upper limit value, and heating is performed at an output lower than 1000 W and higher than the heating conditions. For example, if the heating conditions include an output of 500 W, the heating control unit 113 may generate short-time heating conditions including heating at 800 W or 600 W in addition to heating at 1000 W.

[0060] 1000[W]×120[seconds]+500[W]×120[seconds]=180000…(2)

[0061] The heating control unit 113 judges whether or not short-time heating is possible. For example, when the heating time cannot be shortened by using the short-time heating condition compared to the input heating condition, or the shortened time is equal to or less than a predetermined threshold, there is little point in adopting the short-time heating condition. In this case, the heating control unit 113 judges that short-time heating is not possible. When the heating control unit 113 judges that short-time heating is possible, the display control unit 112 causes the display unit 50 to display the short-time heating icon 54. In addition, the display control unit 112 causes the display unit 50 to display the short-time heating icon 54 while the short-time heating is being performed. In order to distinguish the display state of the short-time heating icon 54, for example, the display control unit 112 may cause the short-time heating icon 54 to flash before the short-time heating is performed, and may cause the short-time heating icon 54 to be constantly displayed while the short-time heating is being performed.

[0062] When heating according to the input heating conditions or short-time heating is performed, the heating control unit 113 causes the sound output unit 70 to output an alarm sound when the heating is completed.

[0063] [1-2. Operation] [1-2-1. Operation of heating device] 4, 5 and 6 are flowcharts showing an example of the operation of the heating device 1 in the first embodiment. 4 shows the operation of the first counter 121 and the second counter 122. Steps S11 to S25 in FIG.

[0064] The operation of FIG. 4 is started at least any one of after the power supply of the heating device 1 is turned on, after the heating device 1 finishes heating, and at other designated timing.

[0065] The control unit 100 refers to the processor 110 and determines whether the heating device 1 has just been powered on (step S11). Here, powering on includes, for example, power being supplied from a state in which the power of the heating device 1 has been completely cut off, and the heating device 1 returning to a normal operating state from a power-saving state. The power-saving state is a state in which the power consumption of the heating device 1 is suppressed by putting each part of the heating device 1, including the control unit 100, into a stopped state or a state in which the frequency of operation is low, and is called, for example, a sleep state. For example, if the heating device 1 is configured to stop supplying power to the volatile memory 120 in the power-saving state, the control unit 100 determines that the power has just been turned on (step S11: YES) immediately after the heating device 1 returns from the power-saving state.

[0066] If the power has just been turned on (step S11: YES), it is highly likely that the count values ​​of the first counter 121 and the second counter 122 have been lost. Therefore, the control unit 100 acquires the count data 133 from the non-volatile storage unit 130 (step S12). The control unit 100 restores the count values ​​of the first counter 121 and the second counter 122 using the count data 133 (step S13), and proceeds to step S14. If the power of the heating device 1 has not just been turned on (step S11: NO), the control unit 100 proceeds to step S14.

[0067] In step S14, the control unit 100 starts decrementing the first counter 121 and the second counter 122 (step S14). The control unit 100 determines whether or not heating by the heating unit 60 has started (step S15), and if heating has not started (step S15: NO), continues decrementing the count value and waits.

[0068] When heating is started (step S15: YES), the control unit 100 starts incrementing the count values ​​of the first counter 121 and the second counter 122 (step S16). Specifically, the control unit 100 increments the count value of the first counter 121 while the magnetron 61 is performing heating at the first output, and increments the count value of the second counter 122 while the magnetron 61 is performing heating at the second output. Furthermore, when the first output is higher than the second output, the control unit 100 may increment the count values ​​of both the first counter 121 and the second counter 122 while the magnetron 61 is performing heating at the first output.

[0069] The control unit 100 determines whether heating by the heating unit 60 has ended (step S17), and if heating has not ended (step S17: NO), continues to increment the count value and waits. If heating has ended (step S17: YES), the control unit 100 ends the increment of the count value (step S18), and overwrites the count values ​​of the first counter 121 and the second counter 122 to the count data 133, thereby storing the count values ​​in the non-volatile storage unit 130 (step S19).

[0070] The control unit 100 waits for a preset second waiting time (step S20) and then starts decrementing the second counter 122 (step S21). Furthermore, the control unit 100 waits for a preset first waiting time (step S22) and then starts decrementing the first counter 121 (step S23). The second waiting time is a waiting time from when the magnetron 61 stops until the second counter 122 is decremented. For the first counter 121, the sum of the first waiting time and the second waiting time is set as the waiting time from when the magnetron 61 stops until the first counter 121 is decremented. The first waiting time and the second waiting time are limitations provided in order to decrement the count value after the temperature of the magnetron 61 drops, and may be omitted depending on the specifications of the magnetron 61, etc.

[0071] The control unit 100 determines whether or not a condition for stopping the operation of the heating device 1 is met (step S24). Stopping the operation includes, for example, transitioning to the above-mentioned power saving state. This condition is, for example, that a period during which the operation panel 3 is not operated and the heating unit 60 is not operated continues for a set time or longer. If the condition is met (step S24: YES), the control unit 100 overwrites the count values ​​of the first counter 121 and the second counter 122 to the count data 133, thereby storing the count values ​​in the non-volatile storage unit 130 (step S25). If the condition is not met (step S24: NO), the control unit 100 returns to step S15.

[0072] 4, the operation of the heating device 1 has been described as a flow chart, but interrupt processing may be performed in response to an operation on the operation panel 3. For example, when heating by the heating unit 60 is started during the waiting time of steps S20 and S22, or at other timing, the control unit 100 may start incrementing the first counter 121 and the second counter 122 by interrupt processing (step S16).

[0073] 5 and 6 show the operation of the heating device 1 to heat an object to be heated. Steps S31 to S34 are executed by the reception unit 111, steps S35 to S39 and S41 to S44 are executed by the heating control unit 113, and step S40 is executed by the display control unit 112. The operation in FIG. 5 is started when triggered by the receipt of an operation by the operation unit 3A.

[0074] The control unit 100 receives a microwave heating instruction from the microwave heating instruction key 31 (step S31). The control unit 100 receives a microwave output specification from the microwave heating instruction key 31 or the dial 39 (step S32), and receives a heating time specification from the dial 39 (step S33). When the control unit 100 receives an instruction to start heating from the start key 33 by operating the start key 33 (step S34), it executes a short-time heating determination process (step S35).

[0075] The short-time heating determination process is a process for determining whether short-time heating is possible or not, and for generating short-time heating conditions. FIG. 6 shows the details of the short-time heating determination process. Steps S61 to S71 in FIG.

[0076] The control unit 100 selects an output to be used for determining whether or not it can be used for short-time heating among outputs that the heating device 1 can execute (step S61). Specifically, the control unit 100 selects one of outputs that are higher than the heating conditions received in steps S32 to S33 among outputs that the heating device 1 can execute (step S61). The control unit 100 determines whether or not the available output time for the output selected in step S61 is equal to or greater than a threshold (step S62). For example, the control unit 100 calculates the available output time (seconds) by dividing the difference between the count value and the upper limit value of the counter corresponding to the selected output by the added value per second. The control unit 100 compares the available output time with a preset threshold, and makes a negative determination if the available output time is below the threshold.

[0077] If the available output time is not equal to or greater than the threshold (step S62: NO), the control unit 100 proceeds to step S68, which will be described later. If the output possible time is equal to or greater than the threshold (step S62: YES), the control unit 100 calculates a heating time for obtaining a heating amount corresponding to the heating condition with the output selected in step S61 (step S63). The control unit 100 determines whether the heating time calculated in step S63 exceeds the output possible time (step S64). If the calculated heating time exceeds the output possible time (step S64: YES), the control unit 100 calculates a heating time for obtaining a heating amount corresponding to the heating condition by combining a plurality of outputs (step S65). In step S65, the control unit 100 generates a short-time heating condition including, for example, the output selected in step S63 and the output specified as the heating condition, and calculates the total heating time of the short-time heating. After the process of step S65, the control unit 100 proceeds to step S66. If the calculated heating time does not exceed the output possible time (step S64: NO), the control unit 100 proceeds to step S66.

[0078] In step S66, the control unit 100 determines whether the difference between the calculated heating time and the heating time specified as the heating condition is equal to or greater than a reference value (step S66). If the difference in heating time is smaller than the reference value (step S66: NO), the control unit 100 proceeds to step S68, which will be described later. This causes the heating device 1 to not perform short-time heating, which has little effect in shortening the heating time, and prevents the user's expectations for short-time heating from being damaged.

[0079] If the difference in heating time is equal to or greater than the reference value (step S66: YES), control unit 100 temporarily stores the short-time heating condition in memory 120 (step S67), and proceeds to step S68.

[0080] In step S68, the control unit 100 determines whether or not there is an undetermined output among outputs that the heating device 1 can execute and that are higher than the output specified as the heating condition (step S68). That is, the control unit 100 determines whether or not there is an output that has not been selected as a determination target in step S61. If there is an undetermined output (step S68: YES), the control unit 100 returns to step S61.

[0081] If there is no undetermined output (step S68: NO), the control unit 100 determines whether or not there is a short-time heating condition stored in the memory 120 (step S69). If there is a short-time heating condition (step S69: YES), the control unit 100 selects the short-time heating condition with the shortest heating time (step S70) and proceeds to step S36 in Fig. 5. If there is no corresponding short-time heating condition (step S69: NO), the control unit 100 determines that short-time heating is not possible (step S71) and proceeds to step S36 in Fig. 5.

[0082] Returning to FIG. 5, the control unit 100 determines whether or not short-time heating is possible based on the result of the short-time heating determination process (step S35) (step S36). If it is determined that short-time heating is not possible (step S36: NO), the control unit 100 starts heating by the heating unit 60 according to the heating conditions accepted in steps S32 to S33 (step S37). The control unit 100 waits until the heating is completed (step S38), and after the heating is completed, notifies the completion of the heating (step S39). In step S39, the control unit 100 causes, for example, the sound output unit 70 to output a notification sound.

[0083] If the short-time heating condition is selected in the short-time heating determination process (step S35), the control unit 100 determines in step S36 that short-time heating is possible (step S36: YES). In this case, the control unit 100 causes the short-time heating icon 54 on the display unit 50 to flash to indicate that short-time heating is possible (step S40). The flashing of the short-time heating icon 54 corresponds to a notification that short-time heating is possible. The control unit 100 determines whether or not an instruction for short-time heating has been given (step S41). The instruction for short-time heating is specifically an operation of the short-time heating key 41.

[0084] If short-time heating has not been instructed (step S41: NO), the control unit 100 determines whether or not a preset time limit has elapsed since displaying that short-time heating is possible (step S42). If the time limit has not elapsed (step S42: NO), the control unit 100 returns to step S41. If the time limit has elapsed (step S42: YES), the control unit 100 proceeds to step S37.

[0085] If a short-time heating command is issued (step S41: YES), the control unit 100 starts heating by the heating unit 60 (step S43) according to the short-time heating conditions selected in the short-time heating determination process (step S35). The control unit 100 waits until the heating is completed (step S44), and proceeds to step S39 after the heating is completed.

[0086] [1-2-2. Transition of display in heating device] FIG. 7 is an explanatory diagram showing an example of a display transition of the heating device 1 in the first embodiment, and shows the operation shown in FIG.

[0087] When an output is specified by operating the microwave heating command key 31 (step S32), the display control unit 112 causes the specified output to be displayed on the numerical display unit 51. When a heating time is specified by operating the dial 39 (step S33), the display control unit 112 causes the specified heating time to be displayed on the numerical display unit 51. After specifying the heating time, the user can start heating by operating the start key 33. For this reason, the display control unit 112 causes the display unit 50 to display a start guide icon 53, to inform the user that the start key 33 can be operated.

[0088] Furthermore, when it is determined that short-time heating is possible by the short-time heating determination process (FIG. 6), the display control unit 112 causes the short-time heating icon 54 to flash on the display unit 50. The flashing of the short-time heating icon 54 notifies the user that heating can be completed in a shorter time than the heating conditions input by the user.

[0089] When the short-time heating key 41 is operated within the time limit while the short-time heating icon 54 is flashing, the heating control unit 113 starts short-time heating. At this time, the display control unit 112 switches the flashing display of the short-time heating icon 54 to a constant display. This notifies the user that short-time heating is being performed.

[0090] [1-3. Effects, etc.] As described above, the heating device 1 that heats an object to be heated by the heating unit 60 includes the heating unit 60 that can output microwaves at a plurality of different outputs, and the operation unit 3A that accepts input of heating conditions including the heating time and output of the heating unit 60. The heating device 1 includes a control unit 100 that operates the heating unit 60 based on the heating conditions. The operation unit 3A includes a short-time heating key 41 that instructs short-time heating, which includes operating the heating unit 60 at an output higher than the heating conditions.

[0091] According to this, an operation of heating an object to be heated at an output higher than the output specified by the user can be instructed by a simple operation, thereby improving the convenience of the user with regard to cooking.

[0092] Short-time heating key 41 accepts an instruction for short-time heating, which includes operating heating unit 60 at its maximum output.

[0093] According to this, by utilizing the maximum output of the heating device 1, heating can be performed in a shorter time.

[0094] The control unit 100 determines the heating time of the short-time heating so that the amount of heat in the short-time heating corresponds to the heating conditions.

[0095] This allows heating to be performed for a short period of time so as to obtain a heat amount corresponding to the heating conditions input by the user, and the required heating can be performed in a shorter period of time.

[0096] The control unit 100 determines the heating time of the heating unit 60 when performing short-term heating, based on the amount of heat applied to the object to be heated and the operation history of the heating unit 60.

[0097] This makes it possible to avoid excessive load on the heating unit 60 and perform heating in a short time, thereby allowing the object to be heated appropriately in a shorter time.

[0098] The control unit 100 acquires the available output time during which the heating unit 60 can output microwaves at a higher output than the heating condition. The control unit 100 determines the heating time and output of the heating unit 60 in short-time heating so that the time during which the heating unit 60 is operated at a higher output than the heating condition does not exceed the available output time and the heating amount in short-time heating corresponds to the heating condition.

[0099] According to this, heating can be performed for a short time by operating the heating unit 60 so as not to exceed the limit, and the object to be heated can be appropriately heated in a shorter time.

[0100] When the heating time for setting the heating amount in the short-time heating to the heating amount corresponding to the heating condition exceeds the possible output time, the control unit 100 executes short-time heating including a first period and a second period. The first period is a period during which the heating unit 60 operates at an output higher than the heating condition. The second period is a period during which the heating unit 60 operates at an output included in the heating condition.

[0101] This allows multiple outputs to be utilized to achieve the required heating in a shorter period of time.

[0102] The control unit 100 determines the lengths of the first period and the second period such that the sum of the heating amount in the first period and the heating amount in the second period is the heating amount corresponding to the heating conditions.

[0103] This allows multiple outputs to be utilized to achieve the required heating in a shorter period of time.

[0104] The heating device 1 includes a notification unit. The notification unit includes, for example, a display unit 50 that displays a short-time heating icon 54, and a sound output unit 70. The control unit 100 causes the notification unit to notify that short-time heating is possible when the output possible time is equal to or greater than a threshold value. This allows the user to be notified that short-time heating can be performed, and the user can operate the short-time heating key 41 in accordance with the notification to complete heating more easily and in a shorter time. This improves the user's convenience regarding cooking.

[0105] When the heating time for short-time heating is shorter than the heating conditions, the control unit 100 notifies the user, via the notification unit, that short-time heating is possible.

[0106] This allows the user to more reliably shorten the heating time by operating short-time heating key 41 in response to the notification.

[0107] After receiving an operation to instruct the start of heating through the operation unit 3A, the control unit 100 notifies the user, through the notification unit, that short-time heating is possible.

[0108] According to this, after the heating conditions input by the user are confirmed, the user is notified that short-time heating can be performed. Therefore, the user can more reliably shorten the heating time by operating short-time heating key 41 in accordance with the notification.

[0109] If the state in which the short-time heating key 41 is not operated continues for a predetermined time or longer after notifying that short-time heating is possible, the control unit 100 operates the heating unit 60 according to the heating conditions.

[0110] According to this, when the user does not want to perform short-time heating, heating is promptly performed based on the heating conditions input by the user, thereby improving the convenience of the user with regard to heating and cooking.

[0111] The heating device 1 includes a memory 120 that temporarily stores data, and a nonvolatile storage unit 130 that nonvolatilely stores data. The control unit 100 stores a first counter 121 and a second counter 122 that indicate the operating state of the heating unit 60 in the memory, and updates the first counter 121 and the second counter 122 according to the operation of the heating unit 60. The control unit 100 calculates an output possible time based on the first counter 121 and the second counter 122. When the operating state of the heating device 1 becomes a predetermined state, the control unit 100 stores count data 133 that indicates the count values ​​of the first counter 121 and the second counter 122 in the nonvolatile storage unit 130. The control unit 100 then reads out the count data 133 from the nonvolatile storage unit 130 and stores it in the memory 120.

[0112] According to this, by storing the first counter 121 and the second counter 122 related to the state of the heating unit 60 in the memory 120, it is possible to easily update the first counter 121 and the second counter 122. Furthermore, by storing the count data 133 in the non-volatile storage unit 130, it is possible to prepare for the loss of the first counter 121 and the second counter 122. Therefore, the state of the heating unit 60 can be appropriately managed.

[0113] The heating device 1, which heats an object to be heated by the heating unit 60, includes the heating unit 60 capable of outputting microwaves at a plurality of different outputs, and an operation unit 3A that accepts input of heating conditions including the heating time and output of the heating unit 60. The heating device 1 includes a control unit 100 that operates the heating unit 60 based on the heating conditions. The operation unit 3A includes a short-time heating key 41 that instructs short-time heating including operating the heating unit 60 at an output higher than the heating conditions. The control unit 100 acquires an output-available time during which the heating unit 60 can output microwaves at an output higher than the heating conditions. The control unit 100 determines the heating time and output of the heating unit 60 in short-time heating so that the time during which the heating unit 60 is operated at an output higher than the heating conditions does not exceed the output-available time, and the heating amount in short-time heating is the heating amount corresponding to the heating conditions. According to this, the operation of heating the object to be heated at a higher output than the output specified by the user can be instructed by a simple operation. Then, the heating unit 60 can be operated so as not to exceed the limit, and heating can be performed for a short time. Therefore, the convenience of the user regarding cooking can be improved.

[0114] The heating device 1 includes a heating unit 60 configured to be capable of outputting microwaves at a plurality of different outputs and for heating an object to be heated, and an operation unit 3A for receiving input of heating conditions including the heating time and output of the heating unit 60. The heating device 1 includes a control unit 100 for operating the heating unit 60 based on the heating conditions. The control unit 100 acquires an output-available time during which the heating unit 60 is capable of outputting microwaves at an output higher than the heating conditions. The control unit 100 determines the heating time and output of the heating unit 60 in short-time heating such that the time during which the heating unit 60 is operated at an output higher than the heating conditions does not exceed the output-available time, and the heating amount in short-time heating corresponds to the heating conditions. According to this, the operation of heating the object to be heated at a higher output than the output specified by the user can be instructed by a simple operation. Then, the heating unit 60 can be operated so as not to exceed the limit, and heating can be performed for a short time. Therefore, the convenience of the user regarding cooking can be improved.

[0115] The heating device 1, which heats an object to be heated by a heating unit 60, includes the heating unit 60 capable of outputting microwaves at a plurality of different outputs, and an operation unit 3A that accepts input of heating conditions including the heating time and output of the heating unit 60. The heating device 1 includes a control unit 100 that operates the heating unit 60 based on the heating conditions. The control unit 100 executes short-time heating that includes operating the heating unit 60 at an output higher than the heating conditions.

[0116] According to this, by heating the object to be heated at an output higher than the output specified by the user, the object can be heated in a shorter time, thereby improving the convenience of the user with regard to cooking.

[0117] The control method for the heating device of the present disclosure is a control method for a heating device 1 including a heating unit 60 capable of outputting microwaves at a plurality of different outputs, and an operation unit 3A that accepts input of heating conditions including heating time and output of the heating unit 60. This control method performs short-time heating including operating the heating unit 60 based on the heating conditions by a control unit 100 that controls the heating unit 60, and operating the heating unit 60 at a maximum output higher than the heating conditions in response to operation of a short-time heating key 41 provided in the operation unit 3A. According to this, the same effects as those of the heating device 1 described above can be achieved.

[0118] The control method of the heating device of the present disclosure is a control method of the heating device 1 including a heating unit 60 capable of outputting microwaves at a plurality of different outputs and an operation unit 3A that accepts input of heating conditions including the heating time and output of the heating unit 60. This control method is a control method for performing short-time heating including operating the heating unit 60 based on the heating conditions by the control unit 100 that controls the heating unit 60 and operating the heating unit 60 at a maximum output higher than the heating conditions in response to operation of the short-time heating key 41 provided on the operation unit 3A. In this control method, the control unit 100 acquires an output possible time during which the heating unit 60 can output microwaves at an output higher than the heating conditions. The control unit 100 determines the heating time and output of the heating unit 60 in short-time heating so that the time during which the heating unit 60 is operated at an output higher than the heating conditions does not exceed the output possible time and the heating amount in short-time heating is the heating amount corresponding to the heating conditions. According to this, the same effects as those of the heating device 1 described above can be achieved.

[0119] The control program 131 of the present disclosure is a program that causes the processor 110 to function, which controls the heating device 1 including a heating unit 60 capable of outputting microwaves at a plurality of different outputs and an operation unit 3A that accepts input of heating conditions including the heating time and output of the heating unit 60. The control program 131 causes the processor 110 to function as a control unit 100. The control unit 100 operates the heating unit 60 based on the heating conditions, and performs short-time heating including operating the heating unit 60 at a maximum output higher than the heating conditions in response to operation of a short-time heating key 41 provided in the operation unit 3A. According to this, the same effects as those of the heating device 1 described above can be achieved.

[0120] (Embodiment 2) [2-1. Operation of the heating device] FIG. 8 is a flowchart showing an example of the operation of the heating device 1 in the second embodiment. The configuration of the heating device 1 of the embodiment 2 is the same as that of the heating device 1 described in the embodiment 1. In addition, in the flowchart of Fig. 8, the same step numbers are assigned to the processes common to the operations described in Fig. 5, and the description thereof will be omitted.

[0121] In the second embodiment, when the start key 33 is operated (step S34), the control unit 100 judges whether or not the output input in step S32 is an output that does not require switching to high output (step S45). An output that does not require switching to high output is, for example, a low output among a plurality of outputs in the microwave oven function of the heating device 1. Specifically, a configuration is assumed in which the magnetron 61 can output microwaves at six levels of output, 150W, 300W, 500W, 600W, 800W, and 1000W. In this case, the user can select an output to be used for heating the object to be heated from five levels of output, 150W, 300W, 500W, 600W, and 800W, by operating the microwave heating instruction key 31 or the dial 39. In this configuration, the lowest output of 150W and the second lowest output of 300W are set as outputs that do not require switching to high output. The number of outputs that do not require switching to high output may be just one or may be multiple.

[0122] A user can easily understand that when the heating device 1 performs heating at a low output, the heating time is longer than when the heating device 1 performs heating at other outputs. Therefore, when a low output is specified by the user's operation, it is presumed that the user intends to perform heating at a low output and for a long heating time. In such a case, even if the short-time heating icon 54 is displayed, the user is unlikely to select short-time heating. For this reason, if one or more outputs on the lowest side among the outputs selectable in the heating device 1 are set in advance as outputs that do not require switching to high output, the process related to short-time heating can be omitted, which is efficient.

[0123] If the control unit 100 determines that the input output is an output that does not require switching to high output (step S45: YES), the control unit 100 proceeds to step S37 and starts heating according to the heating conditions. If the control unit 100 determines that the input output in step S32 is not an output that does not require switching to high output (step S45: NO), the control unit 100 proceeds to step S35 and executes a short-time heating determination process.

[0124] In this way, in the second embodiment, when the output specified by the user is an output that does not require switching to high output (step S45: YES), heating is promptly started according to the heating conditions. In this case, the short-time heating determination process and the process of blinking the short-time heating icon 54 are omitted. This shortens the user's waiting time and allows heating to be performed more efficiently.

[0125] [2-2. Effects, etc.] According to the heating device 1 of the second embodiment, in addition to the effects described in the first embodiment, when it is highly likely that the user does not want short-time heating, the short-time heating determination process and the process of blinking the short-time heating icon 54 can be omitted, and heating can be quickly performed according to the heating conditions. This can shorten the user's waiting time and improve the processing efficiency of the heating device 1.

In addition, it is also possible to combine the components described in the above-mentioned first and second embodiments to create new embodiments. Therefore, other embodiments will be exemplified below.

[0127] For example, in the above embodiment, the dial 39 is provided as a configuration for inputting the heating time, but this is just one example. For example, a configuration may be adopted in which a plurality of time setting keys to which times are assigned are provided on the first operation unit 30, and the heating time can be input using these time setting keys.

[0128] In the above embodiment, the heating device 1 equipped with multiple heating means including heater heating and microwave heating has been described as an example, but the present disclosure can also be applied to a heating device equipped with only a microwave oven function using microwave heating as a heating means. In addition, the heating device 1 may be configured to perform microwave heating with multiple outputs, and there is no restriction on the maximum and minimum values ​​of the output of the heating device 1, or the number of outputs. In addition, the present disclosure can be applied to both a heating device 1 for commercial use and a heating device 1 for home use.

In other words, it is not necessarily required to implement hardware corresponding to each part individually, and it is also possible to implement a configuration in which one processor executes a program to realize the functions of each part. Also, some of the functions realized by software in the above-mentioned embodiment may be hardware, or some of the functions realized by hardware may be software.

[0130] The "programs" in the above-described embodiments can be non-temporarily recorded on a recording medium that is readable by the processor 110, for example. As the recording medium, a magnetic or optical recording medium or a semiconductor memory device can be used. In addition, these programs can be stored in a server device or the like, and the heating device 1 can download the programs from the server device to realize the above-described operations.

[0131] The processor 110 may be composed of a single processor or multiple processors. These processors may be hardware programmed to realize the corresponding functional units. That is, these processors may be composed of, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0132] The step units of the operations shown in each of Figures 5 to 8 are divided according to the main processing contents in order to facilitate understanding of the operations, and the operation is not limited by the manner in which the processing units are divided or the names thereof. The operations may be divided into more step units according to the processing contents. Furthermore, one step unit may be divided so as to include more processing. Furthermore, the order of the steps may be appropriately changed within a range that does not impede the purpose of the present disclosure.
