DETAILED DESCRIPTION OF THE INVENTION

[0011] (Findings that formed the basis of this disclosure) At the time when the inventors arrived at the idea of ​​the present disclosure, there was a technology in a cooking appliance that allowed the user to set various heating conditions, such as the heating course, heating time, etc., using an operation unit. However, the conventional technology did not allow the user to select whether or not to recall the settings from the previous cooking session, and the inventors discovered a problem in that there was a need for convenience in operation for both users who wanted to recall the settings from the previous cooking session and users who did not want to recall the settings from the previous cooking session. In order to solve this problem, the inventors came up with the subject matter of the present disclosure.

[0012] Therefore, the present disclosure provides a cooking device, a control method for a cooking device, and a program that can improve the convenience of users in cooking.

[0013] Hereinafter, embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or redundant explanation of substantially the same configuration may be omitted.

[0014] 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.

[0015] (Embodiment 1) [1-1.Configuration] [1-1-1. Configuration of the cooking device] Fig. 1 is a perspective view of a cooking device 1 in embodiment 1. The cooking device 1 shown in Fig. 1 has a box-shaped cabinet 2. In Fig. 1 and Fig. 2 described below, arrows indicate directions corresponding to the cabinet 2 when the cooking device 1 is installed. 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.

[0016] A door 4 is provided on the front of the cabinet 2 so as to be able to be opened and closed, and when a user grasps and pulls down a handle 5 to open the door 4, a heating chamber 7 provided inside the cabinet 2 is exposed. The heating chamber 7 contains an object to be heated by the cooking device 1. The cooking device 1 cooks the object by irradiating microwaves onto the object contained in the heating chamber 7. In this embodiment, the object to be heated is food or beverage.

[0017] An operation panel 3 is disposed below the door 4. In this embodiment, the operation panel 3 is disposed on the door 4, but the door 4 and the operation panel 3 may be separated and the operation panel 3 may be disposed to the right of the door 4. The operation panel 3 includes switches and the like that accept operations by the user, as will be described later.

[0018] Cooking device 1 heats an object to be heated housed in heating chamber 7 by a microwave oven function using microwaves. Cooking device 1 described in this embodiment also has an oven function and a grill function that heat an object to be heated using a graphite heater or the like, but these functions are not essential to the configuration of the present disclosure.

[0019] [1-1-2. Configuration of the operation unit] FIG. 2 is a front view of operation panel 3 according to the first embodiment.

[0020] The operation panel 3 is located on the lower right side of the door 4 as a first operation section, and includes a range key 30, a speed key 31, a cancel key 32, and a start / confirm key 33. The user can instruct the start of heating by pressing the start / confirm key 33 backward. In addition, an encoder 33a is located around the start / confirm key 33, and as will be described later, the set output and set time values ​​can be decreased by rotating the encoder 33a counterclockwise, and the set output and set time values ​​can be increased by rotating the encoder 33a clockwise. In addition, the user can confirm the set output and set time by pressing the start / confirm key 33 backward.

[0021] The operation panel 3 is arranged on the lower left side of the door 4 as a second operation section, and is provided with a fry warming key 40, a toast key 41, and a standard grill key 42.

[0022] The first operating unit and the second operating unit constitute an operating unit. The arrangement position and order of the keys may be any. In addition to or in place of the first operating unit and the second operating unit, a grill key for setting the grill heating time and an oven key for setting the oven heating temperature and heating time may be arranged.

[0023] Each key other than the encoder 33a may be a switch attached to the surface of the operation panel 3, or may be a switch embedded behind a flexible surface panel that forms the surface of the operation panel 3. Furthermore, each key other than the encoder 33a may be configured with one or more contact sensors that are provided on the surface panel of the operation panel 3 and detect contact operations by the user. Specifically, the range key 30, the cancel key 32, and the start / enter key 33 may each be associated with an operation position of a contact operation detected by a contact sensor.

[0024] The range key 30 is a key operation unit that instructs the user to select the microwave function from among multiple functions such as the microwave function, oven function, and grill function that the cooking appliance 1 has. The cancel key 32 is a key operation unit that instructs the user to cancel the content designated by operating the range key 30, the start / enter key 33, and the encoder 33a. The start / enter key 33 is a key operation unit that instructs the user to confirm the content designated by operating the range key 30 and the encoder 33a, and to perform an operation according to the content designated.

[0025] The cooking device 1 can switch between multiple outputs in its microwave oven function. The output of the cooking device 1 refers to, for example, the output value of microwaves, and in this embodiment, an example is given in which the output can be switched between six levels: 150 W (watts), 300 W, 500 W, 600 W, 800 W, and 1000 W. These six levels of output are the output of the heating unit 60, which will be described later, and can be controlled by the user's operation. This is just one example, and there is no limitation on the output of the cooking device 1 to which the present disclosure is applied.

[0026] The first operation of the range key 30 is an instruction to select the microwave function. Any further operation of the range key 30 within a predetermined time after the first operation of the range key 30 is an instruction to switch the output of the microwave function. For example, in response to the first operation of the range key 30, the initial value of 600 W is selected as the output of the microwave function of the cooking appliance 1. Any subsequent operation of the range key 30 is an instruction to switch the output of the microwave function of the cooking appliance 1 in sequence. In this embodiment, the output is switched in the order of 600 W, 500 W, 300 W, 150 W, 1000 W, 800 W, and 600 W, and any further operation will switch in a cyclical manner in the above order. Of course, any other order of switching is also possible.

[0027] In addition, in this embodiment, the second operation unit is mainly provided with a key operation unit that accepts operations related to the automatic heating function that heats the heated object according to a predetermined program, but the first operation unit and the second operation unit may also include other key operation units, such as a key operation unit that accepts operations related to the oven function (oven key) and grill function (grill key) of the heating cooker 1, and a key operation unit that accepts operations related to the automatic heating function that heats the heated object according to a predetermined program.

[0028] The encoder 33a is an operation unit that accepts a rotation operation. The operation of rotating the encoder 33a is, for example, an operation of inputting a numerical value. Specifically, the numerical value can be increased by rotating the encoder 33a clockwise when viewed from the front, and decreased by rotating the encoder 33a counterclockwise when viewed from the front. The numerical value input by the encoder 33a is, for example, the time for heating using the microwave function, i.e., the heating time. When the start / enter key 33 is operated with a specific numerical value determined by the rotation operation of the encoder 33a, the heating time input by the encoder 33a is determined.

[0029] Furthermore, an operation to instruct switching of the output in the microwave oven function may be executed by using encoder 33a. For example, with the initial value of 600 W selected as the output of cooking device 1, rotating encoder 33a clockwise may switch the output in the order of 800 W, 1000 W, 150 W, 300 W, and 500 W, and rotating encoder 33a counterclockwise may switch the output in the order of 500 W, 300 W, 150 W, 1000 W, and 800 W. The switching of the output by operating encoder 33a may not be cyclical.

[0030] Furthermore, an operation to instruct switching of the output of the microwave oven function may be executed by pressing range key 30 multiple times. For example, when the initial value of 600 W is selected as the output of cooking device 1, pressing range key 30 may switch the output to 500 W, and each time range key 30 is pressed, the output may switch in the order of 500 W, 300 W, 150 W, and 800 W. The switching of the output by operating range key 30 may not be cyclical.

[0031] In this way, heating conditions including the output of the microwave oven function and heating time are input using the range key 30, start / enter key 33, and encoder 33a. When the start / enter key 33 is operated after the heating conditions have been input, the cooking device 1 heats the object to be heated in accordance with the heating conditions.

[0032] The speed key 31 is used to select a speed at which the cooking device 1 performs microwave cooking. This is a dedicated key operation unit for instructing the user to perform short-time heating. Short-time heating includes heating at a higher output than the heating conditions input by operating the range key 30, start / enter key 33, and encoder 33a, 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 oven function is selected and the speed key 31 is not operated, the cooking appliance 1 performs heating according to the heating conditions, and when the speed key 31 is operated, the cooking appliance 1 performs short-time heating.

[0033] The cooking device 1 of this embodiment can perform short-time heating by operating the speed key 31 after the user inputs the heating conditions. In short-time heating, the cooking device 1 performs heating that matches the input heating conditions by using a higher output. This allows the user to perform the required heating in a shorter time using a method that is easy for the user to perform, improving user convenience.

[0034] In this embodiment, "heating conditions" refers to the heating output and heating time during microwave heating using magnetron 61, and other examples of "heating conditions" include the heating temperature and heating time during oven heating using a heater, the heating output and heating time during grill heating in which a magnetron and a cooking tray that absorbs radio waves are used to heat an object to be heated, and the heating temperature and heating time during steam heating using steam. Usually, two or more heating conditions, such as heating output and heating time, are set, but there may be a heating source and a heating course for which at least one heating condition can be set.

[0035] 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. The display unit 50 may be configured with a full-dot liquid crystal display, or a 7-segment LED may be used to display numbers. For characters other than numbers, the character portion may be made of a translucent plastic or resin, and the characters may be displayed on the display unit by illuminating the character portion from the back with an LED to transmit light. In the example of Figure 2, the display unit 50 is configured to display at least the heating time, heating output, heating menu, and heating course.

[0036] The heating output (W) and heating time (minutes, seconds) are displayed as multi-digit numbers. For example, the output value and heating time selected by operating the range key 30 or the encoder 33a, and the remaining heating time during heating are displayed.

[0037] Furthermore, heating menu items such as "rice," "side dish," and "drink" are displayed as heating menu items. The heating menu items displayed on the display unit 50 are not limited to these menu items.

[0038] Furthermore, heating courses such as "microwave," "grill," "oven," "defrost," and "automatic" are displayed as heating courses. The heating courses displayed on display unit 50 are not limited to these heating courses.

[0039] [1-1-3. Configuration of the control system for cooking appliances] FIG. 3 is a block diagram of the cooking device 1 according to the first embodiment.

[0040] The cooking appliance 1 is provided with a control unit 100 that controls each part of the cooking appliance 1. A first operation unit and a second operation unit that constitute an operation unit are connected to the control unit 100. When the first operation unit receives an operation of the range key 30, the cancel key 32, or the start / enter key 33, it outputs an operation signal corresponding to the operated key to the control unit 100. The encoder 33a in the first operation unit outputs an operation signal indicating the rotation direction and amount of the encoder 33a to the control unit 100 in response to an operation to rotate the encoder 33a. The second operation unit 40 is When the operation of the lightly warming key 40, the toast key 41, or the standard grill key 42 is accepted, an operation signal indicating the operation of each key is output to the control unit 100.

[0041] 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 its 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).

[0042] 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 an "alarm unit."

[0043] The control unit 100 includes a processor 110, a memory 120, and a nonvolatile storage unit 130. The processor 110 is configured with a CPU (Central Processing Unit), an MPU (Micro Processing Unit), etc. The memory 120 is a volatile storage device, and is configured with, for example, RAM (Random Access Memory). The memory 120 forms a work area that temporarily stores programs and data executed by the processor 110. The nonvolatile storage unit 130 is configured with, for example, ROM (Read Only Memory) or flash memory, and nonvolatilely stores programs executed by the processor 110 and data processed by the processor 110.

[0044] For example, the nonvolatile storage unit 130 stores a control program 131, setting data 132, and count data 133.

[0045] 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.

[0046] The receiving unit 111 receives an operation performed by a user on the operation unit based on an operation signal output from the first operation unit and the second operation unit.

[0047] The display control unit 112 controls the display on the display unit 50 in accordance with the operation content received by the reception unit 111 and the control of the heating unit 60 executed by the heating control unit 113.

[0048] 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 substrate 62 to cause the magnetron 61 to oscillate the microwave.

[0049] The heating control unit 113 manages the operating state of the magnetron 61 to protect the magnetron 61. Specifically, it limits the time that 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 "status data."

[0050] 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 an example, and the number of counters is not limited.

[0051] The output power above a predetermined level is, for example, the default output power of the microwave oven function of the cooking appliance 1. The output power is a power value exceeding 600 W, i.e., 1000 W and 800 W in this embodiment. 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 value. These two types of outputs are referred to as the first output and the second output. The first output is the highest output used for heating by the cooking appliance 1, and is 1000 W in this embodiment. The second output is the next highest output after the first output used for heating by the cooking appliance 1, and is 800 W in this embodiment.

[0052] The count value per second that heating control unit 113 adds to first counter 121 is count value A, and the count value per second that heating control unit 113 adds to second counter 122 is count value B. Count value A includes count value A1 and count value A2. Count value A1 is the count value per second that is added to first counter 121 while magnetron 61 outputs microwaves at 1000 W. Count value A2 is the count value per second that is added to first counter 121 while magnetron 61 outputs microwaves at 800 W.

[0053] The count value B includes a count value B1 and a count value B2. The count value B1 is the count value per second added to the second counter 122 while the magnetron 61 outputs microwaves at 1000 W. The count value B2 is the count value per second added to the second counter 122 while the magnetron 61 outputs microwaves at 800 W.

[0054] The count values ​​A1, A2, B1, and B2 may all be different from one another, or may include a common value. The specific values ​​of the count values ​​A1, A2, B1, and B2 are set appropriately 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.

[0055] Each of the first counter 121 and the second counter 122 has an upper limit. When the first counter 121 reaches its upper limit, the heating control unit 113 stops the magnetron 61 from outputting 1000 W. Similarly, when the second counter 122 reaches its upper limit, the heating control unit 113 stops the magnetron 61 from outputting 800 W. In other words, the count value of the first counter 121 limits the first main output of the magnetron 61, and the count value of the second counter 122 limits the second output of the magnetron 61. The upper limit values ​​of the first counter 121 and the second counter 122 may be the same value or different values. These specific values ​​are set appropriately 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 less than the upper limit value of the second counter 122.

[0056] 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 the same value or different values. These specific values ​​are set appropriately 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.

[0057] 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 nonvolatile 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 microwaves can be output at the first 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. This corresponds to the time during which waves can be output, and indicates the time during which the second output can be output.

[0058] Because 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 to the cooking appliance 1 is cut off. For example, if the power to the cooking appliance 1 is turned on shortly after being 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 the present 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 cooking appliance 1. Specifically, the heating control unit 113 stores the count data 133 in the nonvolatile storage unit 130 when the cooking appliance 1 stops heating and when the power to the cooking appliance 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 resets 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."

[0059] The heating control unit 113 executes short-time heating in response to the operation of the speed key 31. Short-time heating is an operation in which the magnetron 61 is operated at a higher output than the heating conditions input by operating the range key 30 and the encoder 33a, 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.

[0060] When short-time heating is performed, the heating control unit 113 determines the output and heating time of the magnetron 61 when performing short-time heating. At this time, the heating control unit 113 determines the output and 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 rephrased as the energy imparted 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.

[0061] When heating or short-time heating is performed according to the input heating conditions, the heating control unit 113 causes the sound output unit 70 to output an alarm sound when the heating is completed.

[0062] Next, in this embodiment, the control unit 100 stores the heating output and heating time of the previous heating using the cooking appliance 1 in the memory 120. When the user presses the range key 30 for a certain period of time or more (for example, 3 seconds or more), the previous values ​​of the heating output and heating time are called up from the memory 120 and displayed on the display unit 50.

[0063] In this embodiment, the previous values ​​of heating time and heating output for microwave heating are described as being able to be recalled, but an oven key, grill key, or steam key may be provided, and by pressing and holding each key for a certain period of time or longer, the previous values ​​of preheating time, preheating temperature, heating time after preheating, and heating temperature after preheating may be recalled in the case of oven heating, or the previous value of heating temperature in the case of grill heating.In the case of steam heating, the previous values ​​of heating temperature and heating time may be recalled.

[0064] Also, instead of the configuration in which the previous value is called by pressing each key for a certain period of time or more, the previous value may be called by pressing each key twice at a predetermined time interval. Double pressing refers to a configuration in which the previous value is recalled when the user presses each key (for example, holding the key down for less than 3 seconds), releases the key, and then presses the key again (for example, the time between the user releasing the key and pressing it again is less than 2 seconds). Instead of double pressing, the previous value may be similarly recalled by pressing the key three or more times.

[0065] [1-2. Operation] [1-2-1. Cooker operation] 4 and 5 are flowcharts showing an example of the operation from when the power supply of the cooking appliance 1 in the first embodiment is turned on until cooking starts.

[0066] The flow leading up to power-on is as follows. The control unit 100 refers to the processor 110 and determines whether the cooking appliance 1 has just been powered on. Here, power-on includes, for example, power being supplied to the cooking appliance 1 after it has been completely shut off, and the cooking appliance 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 cooking appliance 1 is reduced by stopping or reducing the operating frequency of each component of the cooking appliance 1, including the control unit 100, and is called, for example, a sleep state. For example, if the cooking appliance 1 is configured to stop supplying power to the volatile memory 120 in the power-saving state, the control unit 100 determines that the cooking appliance 1 has just been powered on immediately after it returns from the power-saving state.

[0067] In Figure 4, after turning on the power, when the user presses the range key 30, which is one of the cooking menu keys (S001), "range" is displayed on the display unit 50 and the user sets the microwave heating. If the range key 30 is further pressed for a certain period of time or more (S002), and the heating output and heating time (setting 1) from the previous microwave heating are stored in the memory 120 (S003), the previous values ​​(setting 1) are displayed on the display unit 50 (S004).

[0068] The previous value (setting 1) can be changed using the range keys 30 or the encoder 33a, so when a change input for the previous value (setting 1) is made (S005), the previous value (setting value) can be changed (S006). In S005 of Fig. 4, the heating output for the previous value (setting 1) is fixed, and only the heating time can be changed.

[0069] If the previous value (setting 1) is not to be changed (No in S005), heating cooking can be started (S008) by pressing the Start / Enter key 33 (S007). If the Start / Enter key 33 is not pressed (No in S007), the previous value (setting 1) is displayed and the cooking device can enter a standby state for the start of heating or a state in which the previous value (setting 1, i.e., heating time) can be changed.

[0070] If the range key 30 has not been pressed for a certain period of time or longer in S002 (No in S002), or if the heating output and heating time from the previous microwave heating are not stored in the memory 120 (No in S003), such as when microwave heating is being performed for the first time since purchasing the cooking appliance 1 in S003, a screen for setting the heating time (setting item 1) is displayed on the display unit 50 (S009). Here, the user can set the desired heating time (setting 1) using the range key 30 or encoder 33a (S010), and then press the start / enter key 33 (S011) to start cooking (S008).

[0071] Next, the flow from S009 to S011 will be described in detail. Other patterns will also be described, such as when the range key 30 is not pressed for a certain period of time or longer in S002 (No in S002), or when the heating output and heating time from the previous microwave heating are not stored in the memory 120 (No in S003), such as when microwave heating is performed for the first time since purchasing the cooking appliance 1 in S003. In S009, a screen (setting item 1) for setting both the heating output and heating time may be displayed on the display unit 50. Here, the user sets the desired heating time and heating output (setting 1) using the range key 30 or the encoder 33a (S010), and presses the start / enter key 33 (S011) to start cooking (S008).

[0072] Note that the heating output display may be made to flash in order to prompt the user to first set the heating output in S009. The initial heating output display defaults to 600 W, but other outputs may also be used. As described above, the heating output value is configured to change from 600 W each time the encoder 33a is rotated or the range key 30 is pressed. When the desired heating output is displayed, pressing the start / enter key 33 determines the heating output, and then the heating time is set.

[0073] The heating time display may be made to flash to prompt the user to set the heating time. The initial heating time display here defaults to 0 seconds, but any other time may be used. As described above, the heating time value is configured to change each time the encoder 33a is turned or the range key 30 is pressed. When the desired heating time is displayed, pressing the start / enter key 33 determines the heating time, and further pressing the start / enter key 33 starts cooking (S008).

[0074] If the range key 30 is pressed again for a certain period of time or more while the previous value (setting 1) is displayed on the display unit 50 (S004), the default heating conditions may be displayed on the display unit. Furthermore, the default heating conditions may also be changeable.

[0075] Next, Fig. 5 will be described. In Fig. 5, after turning on the power, when the user presses a cooking menu key (here, range key 30), which is one of the cooking menus (S001), "Range" is displayed on display unit 50 and the user sets microwave heating. If range key 30 is further pressed for a certain period of time or more (S002), and the heating output and heating time (setting 1) from the previous microwave heating are stored in memory 120 (S003), the previous values ​​(setting 1) are displayed on display unit 50 (S004).

[0076] Next, if the range key is not pressed again (No in S020), the previous value (setting 1) can be changed using the range keys 30 or encoder 33a, so if there is an input to change the previous value (setting 1) (Yes in S021), the previous value (setting value) can be changed (S022). In S022 of Fig. 5, the heating output for the previous value (setting 1) is fixed, and only the heating time can be changed.

[0077] By changing the heating time, which is the previous value (setting 1) (S022) and pressing the Start / Enter key 33 (S023), cooking can be started (S024). If the Start / Enter key 33 is not pressed (No in S023), the previous value (setting 1) is displayed and the cooking device can enter a standby state for starting heating or a state in which the previous value (setting 1, i.e., heating time) can be changed.

[0078] If the range key is pressed again (Yes in S020), the previous value (setting 2) can be changed using the range keys 30 or encoder 33a, so if there is an input to change the previous value (setting 2) (Yes in S026), the previous value (setting value) can be changed (S027). In S027 of Fig. 5, the heating time for the previous value (setting 1) is fixed, and only the heating output can be changed.

[0079] By changing the heating output from the previous value (setting 2) (S027) and pressing the start / decision key 33 (S028), cooking can be started (S024). If key 33 is not pressed (No in S028), the previous value (setting 1) is displayed and the device is placed in a standby state for the start of heating or in a state where the previous value (setting 1, i.e., heating time) can be changed and input.

[0080] With this configuration, after the previous value is displayed, it is possible to set one or both of the two setting items, namely, the heating time and the heating output.

[0081] If the range key 30 has not been pressed for a certain period of time or longer in S002 (No in S002), or if the heating output and heating time from the previous microwave heating are not stored in the memory 120 (No in S003), such as when microwave heating is being performed for the first time since purchasing the cooker 1 in S003, a screen for setting the heating time (setting item 1) is displayed on the display unit 50 (S009). Here, the user sets the desired heating time (setting 1) using the range key 30 or the encoder 33a (S010) and presses the start / enter key 33 (S028), which confirms the heating time (setting 1), and a screen for setting the heating output (setting item 2) is displayed on the display unit 50 (S029). The user then sets the desired heating output (setting 2) using the range key 30 or the encoder 33a (S030) and presses the start / enter key 33 (S031), allowing cooking to begin (S024).

[0082] With this configuration, when the previous value is not displayed, it is possible to set both of the two setting items, namely, the heating time and the heating output.

[0083] If the range key 30 is pressed again for a certain period of time or more while the previous value (setting 1) is displayed on the display unit 50 (S004), the default heating conditions may be displayed on the display unit. Furthermore, the default heating conditions may also be changeable.

[0084] [1-2-2. Transition of display on cooking appliances] 6 and 7 are diagrams showing an example of screen transitions on the display unit according to the first embodiment.

[0085] In Figure 6, after turning on the power, when the user presses the range key 30, which is one of the cooking many keys, the "range" indicator on the display 50 lights up, as shown in Figure 6(a). If the range key 30 is pressed for a certain period of time or longer, and the heating output and heating time from the previous microwave heating are stored in the memory 120, the display 50 will show the previous values ​​from the previous heating cooking, 600W and 5 minutes 00 seconds, as shown in Figure 6(b). In this state, cooking can be started by pressing the start / enter key 33. When cooking starts, the heating time is counted down, and when it reaches 0 seconds, cooking ends, as shown in Figure 6(f).

[0086] In addition, in the state where the previous value is displayed in FIG. 6(b), at least the heating time can be changed by rotating the encoder 33a or pressing the range key 30.

[0087] When the "Microwave" indicator on the display unit 50 is lit, as shown in Fig. 6(a), and the heating output and heating time from the previous microwave heating are not stored in the memory 120, or when the range key 30 is pressed for less than a certain period of time, the default heating output of 600 W is displayed, as shown in Fig. 6(c). In this case, the heating output value is configured to change from 600 W each time the encoder 33a is rotated or the range key 30 is pressed.

[0088] After the desired heating output is displayed, pressing the Start / Enter key 33 determines the heating output, and then sets the heating time. When setting the heating time, the default heating time of 0 seconds is displayed in the state shown in FIG. 6(d). At this time, rotating the encoder 33a or Each time the range key 30 is pressed, the heating time value changes. When the desired heating time (here, 4 minutes 00 seconds) is displayed, as shown in Figure 6(e), pressing the start / confirm key 33 confirms the heating time and starts cooking. When cooking starts, the heating time is counted down, and when it reaches 0 seconds, cooking ends, as shown in Figure 6(f).

[0089] In FIG. 7, after turning on the power, when the user presses the range key 30, one of the cooking many keys, the display unit 50 lights up with "range" and the default heating output of 600W, as shown in FIG. 7(a). If the range key 30 is pressed for a certain period of time or longer, and the heating time from the previous microwave heating is stored in the memory 120, the display unit 50 will show the previous values ​​from the previous heating cooking, 600W and 5 minutes 00 seconds, as shown in FIG. 7(b). In this state, cooking can be started by pressing the start / enter key 33. When cooking starts, the heating time is counted down, and when it reaches 0 seconds, cooking ends, as shown in FIG. 7(f).

[0090] It should be noted that the heating time can be changed by at least rotating the encoder 33a or pressing the range key 30 while the previous value is displayed in FIG. 7(b).

[0091] When the "Microwave" and "600W" are illuminated on the display unit 50, as shown in Fig. 7(a), and the heating output and heating time from the previous microwave heating are not stored in the memory 120, or if the range key 30 is pressed for less than a certain period of time, the default heating output of 600W and 0 seconds is displayed, as shown in Fig. 7(c). In this case, the heating output value is configured to change from 600W each time the encoder 33a is rotated or the range key 30 is pressed.

[0092] After the desired heating output is displayed, pressing Start / Confirm key 33 determines the heating output, and then the heating time is set. When setting the heating time, the heating time value changes each time encoder 33a is rotated or range key 30 is pressed. After the desired heating time (here, 4 minutes 00 seconds) is displayed, as shown in Figure 7(d), pressing Start / Confirm key 33 determines the heating time and starts cooking. When cooking starts, the heating time is counted down and displayed, and when it reaches 0 seconds, cooking ends, as shown in Figure 6(f).

[0093] In addition, in cases where only one 3-digit or 4-digit 7-segment LED is installed, or in other cases where only one of the heating output value and the heating time value can be displayed on display unit 50, for example, a heating output change key and a heating time change key may be provided on operation panel 3, and when the previous value from the previous heating cooking is displayed on display unit 50, the heating output and heating time may first be displayed alternately at regular intervals, and when the heating time is changed using the heating time change key while these are being displayed alternately, only the changed heating time may be displayed on display unit 50, and when the heating output is changed using the heating output change key, only the changed heating output may be displayed on display unit 50.

[0094] Furthermore, the flows and transitions described with reference to FIGS. 4 to 7 may be configured as a control program that the control unit 100 executes or functions in a processor (computer).
