[0027] (Insights, etc., that form the basis of this disclosure)

[0028] When the inventor conceived of this disclosure, there existed heating cookers that used heaters and microwaves to heat the food. However, when heating with microwaves, the internal temperature of the food rises, generating water vapor from within the food. Therefore, the inventor discovered the problem that, depending on the food, the shape might be distorted due to the water vapor generated during heating, potentially resulting in an unsatisfactory appearance after heating. Solving this problem constitutes the subject matter of this disclosure.

[0029] Furthermore, the inventors discovered the following problem: although it is possible to use the steam generated by heating to remove water-soluble odors from food, if the heating time is shortened for foods whose shape is easily distorted by heating, the odors may not be completely removed depending on the food. To solve this problem, the subject of this disclosure is formed.

[0030] Therefore, this disclosure provides a heating device capable of heating a suitable object, a method for controlling the heating device, and a procedure.

[0031] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. However, sometimes unnecessary detailed descriptions are omitted. For example, detailed descriptions of matters that are already known may be omitted, or descriptions of substantially the same structures may be repeated.

[0032] Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure, and are not intended to limit the subject matter of the claims.

[0033] (Implementation Method 1)

[0034] [1-1. Structure]

[0035] [1-1-1. Structure of the heating device]

[0036] Figure 1 This is a perspective view of the heating device 1 according to Embodiment 1.

[0037] Figure 1 The heating device 1 shown has a box-shaped housing 2. Figure 1 And then Figure 2 and Figure 3 In the diagram, arrows indicate the direction corresponding to the housing 2 in the set state of the heating device 1. The symbol UP indicates upward, the symbol R indicates right, and the symbol FR indicates forward.

[0038] A door 3 is provided on the front surface of the housing 2 in a manner that allows it to be opened and closed. In the heating device 1, when the door 3 is opened, the heating chamber 4 disposed inside the housing 2 is exposed. The heating chamber 4 houses the object to be heated by the heating device 1. The heating device 1 is a cooking appliance that cooks the object to be heated by heating the object housed in the heating chamber 4. In this embodiment, the object to be heated is food.

[0039] An operation panel 5 is disposed on the front surface of the housing 2. Alternatively, the operation panel 5 may be disposed side by side with the door 3. The operation panel 5 includes switches, touch panels, etc., for accepting user operations.

[0040] Figure 2 This is a 3D view of the heating device 1 after door 3 has been removed. Figure 2 This is a perspective view of the heating device 1 after the outer cover of the housing 2 has been removed.

[0041] The heating chamber 4 is roughly rectangular in shape, consisting of a right side 41, a left side 42, a top surface 43, a bottom surface 44, and a back surface 45, all made of metal.

[0042] A microwave heating unit 6 is provided below the heating chamber 4. The microwave heating unit 6 has a mechanism for heating the object to be heated housed in the heating chamber 4 using microwaves. This mechanism is a magnetron 61 that generates microwaves (see reference 61). Figure 4 Antenna 62 (see reference) radiates microwaves generated by magnetron 61 into the interior of heating chamber 4. Figure 4 Waveguide 63 (refer to) guides the microwaves generated by magnetron 61 to antenna 62. Figure 4Furthermore, the mechanism for heating the object housed in the heating chamber 4 using microwaves can also be a semiconductor oscillation module. The bottom surface 44 of the heating chamber 4 is covered by a ceramic plate that allows microwaves to pass through. Then, in the heating chamber 4, the object is heated using microwaves that pass through the bottom surface 44 from the microwave heating unit 6.

[0043] A pair of support members 46 for supporting the heating plate 7 are provided on the right side 41 and left side 42 of the heating chamber 4. The pair of support members 46 are members that extend horizontally in the front-back direction when in the installed state. In this embodiment, a pair of upper support members 46A, a pair of middle support members 46B located below the upper support members 46A, and a pair of lower support members 46C located below the middle support members 46B are provided on the right side 41 and left side 42.

[0044] Additionally, the heating plate 7 is a container coated with a material that generates heat when irradiated with microwaves. The heating plate 7 is supported by any one of a pair of upper support members 46A, a pair of middle support members 46B, and a pair of lower support members 46C, and is housed within the heating chamber 4 while dividing it vertically. Figure 2 The example illustrates a scenario where two heating plates 7 are supported by a pair of upper support members 46A and a pair of middle support members 46B, dividing the heating chamber 4 into three regions.

[0045] A nozzle 47 is formed on the left side 42 of the heating chamber, which sprays out water vapor heated to a high temperature by a steam heater. Water heated by the steam heater is stored in a tank located inside the housing 2 outside the heating chamber 4. The object to be heated in the heating chamber 4 is heated by the water vapor sprayed from the nozzle 47.

[0046] A planar heater unit 81 for heating an object is provided on the top surface 43 of the heating chamber 4. The planar heater unit 81 includes a planar heater, a plate that presses the planar heater against the top surface of the heating chamber 4, and a blocking plate that blocks the upward transfer of heat from the planar heater. The object is heated in the heating chamber 4 by the planar heater unit 81.

[0047] A first air intake 45A and a second air intake 45B, each consisting of multiple perforations, are formed on the back surface 45 of the heating chamber 4. Furthermore, a first air outlet 45C, a second air outlet 45D, a third air outlet 45E, a fourth air outlet 45F, and a fifth air outlet 45G, each consisting of multiple perforations, are also formed on the back surface of the heating chamber 4. The first air outlet 45C extends horizontally above the second air outlet 45D, the third air outlet 45E, the fourth air outlet 45F, and the fifth air outlet 45G. The fifth air outlet 45G extends horizontally below the first air outlet 45C, the second air outlet 45D, the third air outlet 45E, and the fourth air outlet 45F. The second air outlet 45D is located to the left of the first air intake 45A. The third air outlet 45E is formed horizontally between the first air intake 45A and the second air intake 45B. The fourth air outlet 45F is formed to the right of the second air inlet 45B.

[0048] A convection heater unit 82 is disposed behind the rear side 45 of the heating chamber 4. Figure 2 In the diagram, the mechanisms of the convection heater unit 82 are indicated by dashed lines. The convection heater unit 82 includes a first fan 821 that draws air in through a first air intake 45A, a second fan 822 that draws air in through a second air intake 45B, a first heater 823 that heats the air drawn in by the first fan 821 and the second fan 822, and a second heater 824 that heats the air drawn in by the first fan 821 and the second fan 822.

[0049] The first fan 821 and the second fan 822 correspond to an example of an "air supply section".

[0050] The first fan 821 is positioned opposite the first air intake 45A and draws air from the heating chamber 4 through the first air intake 45A. The air drawn in by the first fan 821 is blown out through each air outlet except the fourth air outlet 45F. In particular, air heated by the first heater 823 is blown out through the first air outlet 45C, and air heated by the second heater 824 is blown out through the fifth air outlet 45G.

[0051] Furthermore, the second fan 822 is positioned opposite the second air intake 45B and draws air from the heating chamber 4 through the second air intake 45B. The air drawn in by the second fan 822 is blown out through each air outlet except the second air outlet 45D. In particular, air heated by the first heater 823 is blown out through the first air outlet 45C, and air heated by the second heater 824 is blown out through the fifth air outlet 45G.

[0052] In this way, the convection heater unit 82 circulates air in the heating chamber 4. Furthermore, the convection heater unit 82 uses the air blown from each air outlet to heat the object being heated.

[0053] [1-1-2. Structure of the control system of the heating device]

[0054] Figure 4 This is a block diagram showing the structure of the control system of heating device 1.

[0055] The heating device 1 includes a control device 10, an operation panel 5, and a heating unit 11. The control device 10 is a device for controlling each part of the heating device 1. The control device 10 is connected to the operation panel 5 and the heating unit 11.

[0056] As described above, the operation panel 5 includes a switch, a touch panel, etc. When the switch is operated, the operation panel 5 outputs an operation signal to the control device 10. Furthermore, when the touch panel is touched, the operation panel 5 outputs an operation signal to the control device 10.

[0057] The heating unit 11 heats the heating chamber 4 under the control of the control device 10. The heating unit 11 includes a microwave heating unit 6, a heater heating unit 8, and a steam heating unit 9.

[0058] The microwave heating unit 6 uses microwaves to heat the object housed in the heating chamber 4. The microwave heating unit 6 includes a magnetron 61, an antenna 62, a waveguide 63, and other mechanisms related to microwave-based heating.

[0059] The heater heating section 8 uses a heater to heat the object housed in the heating chamber 4. The heater heating section 8 includes a planar heater unit 81, a convection heater unit 82, and other mechanisms related to heater-based heating.

[0060] The steam heating unit 9 uses steam to heat the object to be heated housed in the heating chamber 4. The steam heating unit 9 includes a water supply tank, a steam heater that heats the water in the tank to generate steam, and other mechanisms related to steam-based heating.

[0061] The control device 10 includes a processor 100 such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit), a memory 110, and interface circuits for connecting to other devices.

[0062] Memory 110 is a memory for storing programs and data. Memory 110 stores control program 111 and data processed by processor 100. Memory 110 has non-volatile storage areas. Furthermore, memory 110 has volatile storage areas, constituting the working area of ​​processor 100. Memory 110 is composed, for example, of ROM (Read Only Memory) or RAM (Random Access Memory).

[0063] Control program 111 is an example of a "program".

[0064] The processor 100 functions as a heating execution unit 101, a receiving unit 102, and a determination unit 103 by reading and executing the control program 111 stored in the memory 110.

[0065] The heating actuator 101 controls the heating unit 11 to heat the object stored in the heating chamber 4. The heating actuator 101 heats the object using a heating mode specified by the user. The heating modes include microwave oven mode, oven mode, steam mode, grilling mode, and other modes.

[0066] In addition, the microwave oven mode is a mode in which the microwave heating unit 6 is used to heat the object being heated.

[0067] The oven mode is a mode in which the heating element 8 is used to heat the food being heated.

[0068] The steam mode is a mode in which the object to be heated is heated by the steam heating unit 9.

[0069] The grilling mode is a mode in which the microwave heating unit 6 and the heater heating unit 8 are used to heat the food placed on the heating plate 7.

[0070] The receiving unit 102 receives the user's instructions to the operating panel 5 based on the operating signals output by the operating panel 5.

[0071] When the user-specified heating mode is grilling mode, the determination unit 103 determines whether the food being heated, stored in the heating chamber 4 and placed on the heating plate 7, is a first food or a second food. If the receiving unit 102 accepts the first food as the type of food being heated, the determination unit 103 determines that the food being heated stored in the heating chamber 4 is a first food; if the receiving unit 102 accepts the second food as the type of food being heated, the determination unit 103 determines that the food being heated stored in the heating chamber 4 is a second food.

[0072] Here, the first food and the second food will be explained.

[0073] The term "first food" refers to food whose shape is easily altered by heating. More specifically, it refers to food whose shape may change significantly from its original state due to internal steam generated during heating. More specifically, it refers to fried food obtained by coating a food shaped to a desired form with batter. Furthermore, it refers to fried food where the filling easily splatters outwards when the batter breaks. It also refers to fried food obtained by shaping a food into a desired shape using methods other than cutting, then coating it with batter. Examples of first foods include croquettes, cream croquettes, and fried cheese sticks.

[0074] Furthermore, the first food item is relatively more prone to spoilage than the second food item, which will be described in detail later.

[0075] Secondary foods are those whose shape does not easily change during heating. More specifically, secondary foods are those whose shape does not significantly change from its original state due to internal steam generated during heating. More specifically, secondary foods are foods that are not fully formed but covered with batter, or foods that have been shaped into a desired form by cutting and then covered with batter. Examples of secondary foods include fried cutlets, dumplings, spring rolls, Japanese fried chicken, Tatsuta fried chicken, chicken nuggets, French fries, hamburger patties, char siu pork, and baked vegetables.

[0076] Furthermore, the second food item is relatively less prone to spoilage compared to the first food item.

[0077] [1-2. Actions]

[0078] Next, the operation of the heating device 1 in this embodiment will be explained.

[0079] Figure 5 This is a flowchart illustrating the operation of heating device 1. Figure 5 At the beginning of the flowchart, the user specifies the heating mode as barbecue mode.

[0080] The receiving unit 102 receives the heating time and the type of object being heated via the operation panel 5 (step S1).

[0081] Next, the determination unit 103 determines whether the heated item stored in the heating chamber 4 is the first food or the second food (step S2). In step S2, the determination unit 103 determines whether the heated item is the first food or the second food based on the type of heated item received by the receiving unit 102 in step S1.

[0082] If the determination unit 103 determines that it is the first food product (step S2: first food product), the heating execution unit 101 determines whether to start heating (step S3). In step S3, if the receiving unit 102 receives the heating start instruction via the operation panel 5, the heating execution unit 101 makes an affirmative determination.

[0083] If it is determined that heating has started (step S3: Yes), the heating execution unit 101 performs the first heating process (step S4).

[0084] The first heating process refers to the heating process when the object being heated is the first food product.

[0085] Figure 6 This is a diagram used to illustrate the first heating process.

[0086] exist Figure 6 The image shows an example of the first heating process.

[0087] Figure 6 The first heating process illustrated herein includes a first microwave heating process, a first heater heating process, a second microwave heating process, and a second heater heating process, and is a heating process performed in the order of the first microwave heating process, the first heater heating process, the second microwave heating process, and the second heater heating process. Furthermore, in Figure 6 In each step of the first heating process illustrated, the first fan 821 and the second fan 822 rotate to deliver air to the heating chamber 4.

[0088] The first microwave heating process is a process in which the object to be heated is heated using the microwave heating unit 6. Figure 6 In the illustrated first heating process, the first microwave heating process is the first process performed. Figure 6 The first microwave heating process illustrated in the example heats the object at an output of 800W (watts).

[0089] The first heater heating process is a process in which the object to be heated is heated using the heater heating section 8. Figure 6 In the first heating process illustrated, the first heater heating process is the second process performed. Figure 6 In the first heater heating process illustrated in the example, the object to be heated is heated by the planar heater of the planar heater unit 81, and the object to be heated is heated from above by energizing only the first heater 823 in the convection heater unit 82.

[0090] At this point, it is preferable to use both heating based on the planar heater unit 81 and heating based on the convection heater unit 82. If the object is heated only by the planar heater unit 81, the sides of the object may not be heated properly, making it difficult to achieve a crispy texture. Furthermore, if the object is heated only by the convection heater unit 82, the heating time may be longer. By using both heating based on the planar heater unit 81 and heating based on the convection heater unit 82, heating can be achieved in a shorter time while improving the texture of the heated object.

[0091] Furthermore, preferably, the convection heater unit 82 is disposed above the interior of the chamber, and at least one of the planar heaters is disposed above the interior of the chamber.

[0092] Heating based on planar heater unit 81 and heating based on convection heater unit 82 can be either alternating or simultaneous.

[0093] The second microwave heating process is a process in which the object to be heated is heated using the microwave heating unit 6. Figure 6 In the first heating process illustrated, the second microwave heating process is the third process performed. Figure 6 The second microwave heating process illustrated in the example heats the object at an output of 600W.

[0094] The second heater heating process is a process in which the object to be heated is heated using the heater heating section 8. Figure 6 In the illustrated first heating process, the second heater heating process is the last process. Figure 6 In the second heater heating process illustrated, the object to be heated is heated by the planar heater of the planar heater unit 81, and the object to be heated is heated from above by energizing only the first heater 823 in the convection heater unit 82.

[0095] At this point, it is preferable to use both heating based on the planar heater unit 81 and heating based on the convection heater unit 82. If the object is heated only by the planar heater unit 81, the sides of the object may not be heated properly, making it difficult to achieve a crispy texture. Furthermore, if the object is heated only by the convection heater unit 82, the heating time may be longer. By using both heating based on the planar heater unit 81 and heating based on the convection heater unit 82, heating can be achieved in a shorter time while improving the texture of the heated object.

[0096] In the first heating process, the heating time based on the heater heating section 8 accounts for more than half of the process time in the first half of the first heating process. In addition, the first half of the first heating process refers to the process from the start of the first heating process until half of the total time of the first heating process has passed.

[0097] exist Figure 6 The example shows the time for each step of the first microwave heating step, the first heater heating step, the second microwave heating step, and the second heater heating step when the total time of the first heating step is set to 100%. Figure 6 In the example, when the total time of the first heating step is set to 100%, the process time of the first microwave heating step is the time corresponding to 5% of the total time of the first heating step. Furthermore, in Figure 6 In the example, when the total time of the first heating process is set to 100%, the process time of the first heater heating process corresponds to 70% of the total time of the first heating process. Furthermore, in Figure 6 In the example, when the total time of the first heating step is set to 100%, the process time of the second microwave heating step is 15% of the total time of the first heating step. Furthermore, in Figure 6 In the example, when the total time of the first heating process is set to 100%, the process time of the second heater heating process is the time corresponding to 10% of the total time of the first heating process.

[0098] It should be noted that, Figure 5 The process times of the first microwave heating step, the first heater heating step, the second microwave heating step, and the second heater heating step shown are merely examples. As long as heating by the heater heating section 8 accounts for more than half of the process time in the first half of the first heating step, the process times of each of the four steps included in the first heating step are not limited to... Figure 7 The process time is shown.

[0099] If, in the first half of the first heating process, the heating time based on the heater heating section 8 accounts for more than half of the process time, then the process time of the first microwave heating process of the first heating process can be within the range of 0% to 25% of the total time of the first heating process.

[0100] Furthermore, as long as the heating based on the heater heating section 8 accounts for more than half of the process time in the first half of the first heating process, the process time of the first heater heating process in the first heating process can be in the range of 25% to 100% of the total time of the first heating process.

[0101] Furthermore, as long as the heating time based on the heater heating section 8 accounts for more than half of the process time in the first half of the first heating process, the process time of the second microwave heating process of the first heating process can be within the range of 0 to 75% of the total time of the first heating process.

[0102] When performing the first heating process, the heating execution unit 101 sets the heating time received in step S1 to 100% to determine the proportion of the process time for each of the first microwave heating process, the first heater heating process, the second microwave heating process, and the second heater heating process. Then, based on the determined proportions, the heating execution unit 101 sequentially performs the first microwave heating process, the first heater heating process, the second microwave heating process, and the second heater heating process. In the first heating process, the heating execution unit 101 counts the elapsed time from the start of heating and switches processes based on the counted elapsed time.

[0103] return Figure 7 The explanation of step S2 is as follows: if the determination unit 103 determines that it is a second food product (step S2: second food product), the heating execution unit 101 determines whether to start heating (step S5). In step S5, if the receiving unit 102 receives a heating start instruction, the heating execution unit 101 makes an affirmative determination.

[0104] When the heating execution unit 101 determines that heating has started (step S5: Yes), it executes the second heating process (step S6).

[0105] The second heating process refers to the heating process when the object being heated is a second food product.

[0106] Figure 7 This is a diagram used to illustrate the second heating process.

[0107] exist Figure 7 The image shows an example of the second heating process.

[0108] Figure 7 The second heating step illustrated herein includes a first microwave heating step, a first heater heating step, and a second microwave heating step, and is a heating step performed in the order of the first microwave heating step, the first heater heating step, and the second microwave heating step. Furthermore, in Figure 7 In each of the illustrated second heating processes, in the first heater heating process and the second microwave heating process, the first fan 821 and the second fan 822 rotate to supply air to the heating chamber 4.

[0109] The first microwave heating process is a process in which the object to be heated is heated using the microwave heating unit 6. Figure 7In the illustrated second heating process, the first microwave heating process is performed first. Figure 7 The first microwave heating process illustrated in the example heats the object at an output of 800W (watts).

[0110] The first heater heating process is a process in which the object to be heated is heated using the heater heating section 8. Figure 7 In the second heating process illustrated, the first heater heating process is the second process performed. Figure 7 In the first heater heating process illustrated in the example, the object to be heated is heated by the planar heater of the planar heater unit 81, and the object to be heated is heated from above by energizing only the first heater 823 of the heater of the convection heater unit 82.

[0111] At this point, it is preferable to use both heating based on the planar heater unit 81 and heating based on the convection heater unit 82. If the object is heated only by the planar heater unit 81, the sides of the object may not be heated properly, making it difficult to achieve a crispy texture. Furthermore, if the object is heated only by the convection heater unit 82, the heating time may be longer. By using both heating based on the planar heater unit 81 and heating based on the convection heater unit 82, heating can be achieved in a shorter time while improving the texture of the heated object.

[0112] Heating based on planar heater unit 81 and heating based on convection heater unit 82 can be either alternating or simultaneous.

[0113] The second microwave heating process is a process in which the object to be heated is heated using the microwave heating unit 6. Figure 7 In the illustrated second heating process, the second microwave heating process is the last process performed. Figure 7 The second microwave heating process illustrated in the example heats the object at an output of 600W.

[0114] In the second heating process, more than half of the total heating time based on the microwave heating unit 6 is performed in the first half of the second heating process. Furthermore, the first half of the second heating process refers to the process from the start of the second heating process until half of the total time of the second heating process has elapsed.

[0115] exist Figure 7 The example shows the time for each step of the first microwave heating step, the first heater heating step, and the second microwave heating step when the total time of the second heating step is set to 100%. Figure 5In the example, when the total time of the second heating step is set to 100%, the process time of the first microwave heating step corresponds to 40% of the total time of the second heating step. Furthermore, in Figure 8 In the example, when the total time of the second heating process is set to 100%, the process time of the first heater heating process corresponds to 50% of the total time of the second heating process. Furthermore, in Figure 9 In the example, when the total time of the second heating process is set to 100%, the process time of the second microwave heating process is the time corresponding to 10% of the total time of the second heating process.

[0116] It should be noted that, Figure 9 The process times of the first microwave heating step, the first heater heating step, and the second microwave heating step shown are merely examples. As long as more than half of the total heating time based on the microwave heating unit 6 is performed in the first half of the second heating step, the process times of each of the three steps included in the second heating step are not limited to [specific time range]. Figure 9 The process time is shown.

[0117] If more than half of the total heating time based on the microwave heating unit 6 is performed in the first half of the second heating process, then the process time of the first microwave heating process in the second heating process can be within the range of 0% to 70% of the total time of the second heating process.

[0118] Furthermore, as long as more than half of the total heating time based on the microwave heating unit 6 is performed in the first half of the second heating process, the process time of the first heater heating process in the second heating process can be in the range of 30% to 100% of the total time of the second heating process.

[0119] Furthermore, as long as more than half of the total heating time based on the microwave heating unit 6 is performed in the first half of the second heating process, the process time of the second microwave heating process of the second heating process can be within the range of 0% to 35% of the total time of the second heating process.

[0120] When performing the second heating process, the heating execution unit 101 sets the heating time received in step S1 to 100% to determine the proportion of the process time for each of the first microwave heating process, the first heater heating process, and the second microwave heating process. Then, based on the determined proportions, the heating execution unit 101 sequentially performs the first microwave heating process, the first heater heating process, and the second microwave heating process. In the first heating process, the heating execution unit 101 counts the elapsed time from the start of heating and switches processes based on the counted elapsed time.

[0121] return Figure 9 As explained, when the first heating process or the second heating process ends, the heating execution unit 101 determines whether the receiving unit 102 has accepted an additional heating execution instruction within a specified period from the end of the heating process (step S7).

[0122] If the heating execution unit 101 determines that the receiving unit 102 has not accepted the additional heating execution instruction (step S7: No), the process ends.

[0123] On the other hand, if the heating execution unit 101 determines that the receiving unit 102 has accepted an additional heating execution instruction (step S7: Yes), it executes heating based on the heater heating unit 8 and the microwave heating unit 6 (step S8). Alternatively, in step S8, the heating execution unit 101 may also execute heating based only on the heater heating unit 8.

[0124] [1-3. Effects, etc.]

[0125] As described above, the heating device 1 includes: a microwave heating unit 6, which uses microwaves to heat an object housed in the heating chamber 4; a heater heating unit 8, which uses a heater to heat the object; and a heating execution unit 101, which controls the microwave heating unit 6 and the heater heating unit 8 to perform a heating process for the object. When the object to be heated is a first food product, the heating execution unit 101 performs the heating process in such a manner that, in the first half of the heating process, heating based on the heater heating unit 8 accounts for more than half of the process time.

[0126] Therefore, in the first part of the heating process, the shape of the first food product can be firmly established by the heating of the heater, and the shape can be prevented from being distorted by water vapor generated from the inside using microwaves. Thus, heating suitable for the object being heated can be performed.

[0127] The heating device 1 includes: a microwave heating unit 6, which uses microwaves to heat an object housed in a heating chamber 4; a heater heating unit 8, which uses a heater to heat the object; and a heating execution unit 101, which controls the microwave heating unit 6 and the heater heating unit 8 to perform a heating process for the object. When the object to be heated is a second food product, the heating execution unit 101 performs the heating process in such a manner that, in the first half of the heating process, it accounts for more than half of the execution time of the heating based on the microwave heating unit 6.

[0128] Therefore, in the first half of the heating process, it is possible to ensure that the microwaves heat the second food for a longer period of time, raising the internal temperature of the food to generate steam before the outer surface is cooked. This allows for heating suitable for the object being heated.

[0129] As the final step in the heating process of the first food product, the heating execution unit 101 performs heating based on the heater heating unit 8.

[0130] This allows moisture adhering to the surface of the first food product to evaporate in the final process. Furthermore, heating of the food can be stopped while moisture adhering to the surface is suppressed, thus providing a food product with a good texture after heating.

[0131] In the heating process of the second food, the heating execution unit 101 heats the object to be heated placed on the heating plate 7. As the final step in the heating process of the second food, the heating is performed based on the microwave heating unit 6.

[0132] Therefore, the surface of the second food item facing the heating plate 7 can be baked and browned in the final process. This allows for heating suitable for the food being heated, and provides a product with even browning and good appearance after heating.

[0133] The heating process includes a first microwave heating process using microwave heating unit 6 and a second microwave heating process using microwave heating unit 6 with a lower heating output than the first microwave heating process. During the heating process, heating unit 101 performs heating based on heater heating unit 8 between the first and second microwave heating processes.

[0134] Therefore, in the second microwave heating process, since both the temperature of the heating plate and the temperature of the heated object are high, the bottom surface of the heated object is easy to bake and color. However, by making the output of the second microwave heating process lower than that of the first microwave heating process, the baking and coloring speed of the heated object is slowed down, which reduces the possibility of overheating.

[0135] The heating execution unit 101 heats the object to be heated placed on the heating plate 7 in the heating process. In the first step of the heating process, heating is performed based on the microwave heating unit 6.

[0136] Therefore, microwaves can be used to efficiently heat the heating plate 7, and the object to be heated placed on the heating plate 7 can be heated appropriately during the heating process.

[0137] The heating device 1 includes a first fan 821 and a second fan 822 that blow air into the heating chamber 4. The heating execution unit 101 blows air using the first fan 821 and the second fan 822 while heating using the heater heating unit 8.

[0138] Therefore, the heat generated from the heating section 8 of the heater can be distributed to every corner of the heating chamber 4, and uneven heating caused by the different positions of the heated object in the heating chamber 4 can be suppressed. Thus, the heated object can be heated appropriately.

[0139] The heating device 1 includes a receiving unit 102 that accepts additional heating execution instructions after the heating process is completed. When the receiving unit 102 accepts an additional heating execution instruction, the heating execution unit 101 performs heating based on the heater heating unit 8 after the heating process is completed.

[0140] Therefore, it is possible to bake and color the heated object during additional heating, and to heat it in a way that produces the appearance desired by the user.

[0141] The heating device 1 includes a receiving unit 102 that accepts additional heating execution instructions after the heating process is completed. When the receiving unit 102 accepts additional heating execution instructions, the heating execution unit 101 performs heating on the object to be heated placed on the heating plate 7 based on the heater heating unit 8 and the microwave heating unit 6 after the heating process is completed.

[0142] Therefore, in the additional heating, both the side of the food facing the heating plate 7 and the side of the food not facing the heating plate 7 can be baked and browned, and the food can be heated in a way that produces the appearance desired by the user.

[0143] The heating device 1 includes a first fan 821 and a second fan 822 that blow air into the heating chamber 4. During additional heating, the heating execution unit 101 blows air using the first fan 821 and the second fan 822 while heating using the heater heating unit 8.

[0144] Therefore, the heat generated from the heating section 8 of the heater can reach every corner of the heating chamber 4, suppressing uneven heating caused by the different positions of the heated objects in the heating chamber 4. Thus, in additional heating, the heated objects can be properly baked and colored to the user's desired effect.

[0145] In the control method of the heating device 1, when the object to be heated housed in the heating chamber 4 is a first food, the heating process of heating the object using microwave and a heater is carried out in the following manner: in the first half of the heating process, heating based on the heater accounts for more than half of the process time.

[0146] Thus, it achieves the same effect as the heating device 1 described above.

[0147] When the object to be heated housed in the heating chamber 4 is a second food product, the heating device 1 performs the heating process in such a manner that the first half of the heating process in which the object to be heated is heated using microwaves and a heater accounts for more than half of the execution time of microwave-based heating performed in the heating process.

[0148] Thus, it achieves the same effect as the heating device 1 described above.

[0149] The control program 111 enables the processor 100 of the heating device 1 to function as a heating execution unit 101 that controls the microwave heating unit 6 and the heater heating unit 8 to heat the object being heated. When the object being heated is a first food product, the heating execution unit 101 performs the heating process in such a way that, in the first half of the heating process, heating based on the heater heating unit 8 accounts for more than half of the process time.

[0150] Thus, it achieves the same effect as the heating device 1 described above.

[0151] The control program 111 enables the processor 100 of the heating device 1 to function as a heating execution unit 101 that controls the microwave heating unit 6 and the heater heating unit 8 to heat the object being heated. When the object being heated is a second food product, the heating execution unit 101 performs the heating process in such a way that it accounts for more than half of the execution time of the heating based on the microwave heating unit 6 in the first half of the heating process.

[0152] Thus, it achieves the same effect as the heating device 1 described above.

[0153] (Other implementation methods)

[0154] As described above, Embodiment 1 has been presented as an example disclosed in this application. However, the technology in this disclosure is not limited to this and can be applied to embodiments with modifications, substitutions, additions, omissions, etc. Furthermore, new embodiments can be created by combining the constituent elements described in Embodiment 1. Therefore, other embodiments will be illustrated below.

[0155] In the above embodiment, the heating of an object placed on the heating plate 7 is illustrated. In other embodiments, the heating process performed by the heating execution unit 101 may also be a process performed on an object not placed on the heating plate 7. For example, it may also be used to heat an object placed on a heating grid.

[0156] In the above embodiment, the structure switches between each heating process based on the passage of time. In other embodiments, the process can also be switched based on the temperature of the heating chamber 4, the temperature of the object being heated, etc. In this other embodiment, the heating device 1 includes a temperature sensor for detecting the temperature of the heating chamber 4, a temperature sensor for detecting the temperature of the object being heated, etc.

[0157] In other embodiments, the proportion of the process time for each step in the heating process can be determined based on the amount of the object being heated in one heating cycle. In this other embodiment, the heating device 1 includes a camera, a weight sensor, etc., as components for detecting the amount of the object being heated.

[0158] In other embodiments, the proportion of the process time for each step in the heating process can be determined based on the type of the first food and, moreover, the type of the second food. In this other embodiment, the heating device 1 includes a camera or similar component for detecting the type of the object being heated.

[0159] In other embodiments, the proportion of the process time for each step in the heating process can be determined based on the temperature of the object being heated at the start of heating. In other embodiments, the heating device 1 includes a temperature sensor that detects the temperature of the object being heated. For example, if the detected temperature of the object being heated is a freezing temperature, the proportion of the first microwave heating step can be increased in the first half of the heating process. Alternatively, the user can input the temperature of the object being heated.

[0160] In other embodiments, the determination unit 103 may also determine whether the heated object is a first food or a second food based on an image captured of the heated object. This image may be a camera captured by the heating device 1, or, if the heating device 1 can communicate with an external terminal (such as a portable PC like a smartphone), a camera captured by that external terminal. In this other embodiment, the determination unit 103 determines whether the heated object is a first food or a second food by performing image processing such as pattern matching and color difference analysis.

[0161] In other embodiments, the determination unit 103 may also determine whether the heated item is a first food or a second food based on information sent from an external terminal capable of communicating with the heating device 1. In this other embodiment, the external terminal sends information indicating the type of heated item accepted by the user to the heating device 1. Furthermore, in this other embodiment, the determination unit 103 determines whether the heated item is a first food or a second food based on information received from the external terminal.

[0162] In other embodiments, the receiving unit 102 may also receive additional heating execution instructions from an external terminal capable of communicating with the heating device 1.

[0163] In other embodiments, microwave-based heating and heater-based heating can be performed simultaneously. For example, in another embodiment, microwave-based heating and heating based on the planar heater unit 81 are performed simultaneously in the latter half of the first heating step. According to this example, it is possible to achieve the effect of cooking in a short time, even when the amount of food being heated is small. Furthermore, when microwave-based heating and heater-based heating are performed simultaneously in the latter half of the first heating step, the microwave output is set to 300W to 400W. Also, when microwave-based heating and heater-based heating are performed simultaneously in the latter half of the first heating step, microwave-based heating may or may not be performed after the simultaneous heating, and heater-based heating may or may not be performed.

[0164] In other embodiments, microwave-based heating and heater-based heating can be alternately and repeatedly performed in the first heating step. This ensures a consistent firing speed on both the surface and back of the heated object, resulting in less shape distortion. This is because the temperature of the heating plate 7 rises during microwave-based heating and falls during heater-based heating; however, by alternating heating, the temperature drop of the heating plate 7 can be suppressed. Furthermore, similarly to other embodiments, microwave-based heating and heater-based heating can also be alternately and repeatedly performed in the second heating step.

[0165] In other embodiments, the final step of the second heating process may also be heating based on a heater.

[0166] In other implementations, such as Figure 9 As shown, the convection heater unit 82 may also consist of only a first fan 821, a first heater 823 (not shown) that heats the air drawn in by the first fan 821, and a second heater 824 (not shown) that heats the air drawn in by the first fan 821.

[0167] The first fan 821 is positioned opposite the first air intake 45A and draws air from the heating chamber 4 through the first air intake 45A. The air drawn in by the first fan 821 is blown out through each air outlet except for the fourth air outlet 45F. In particular, air heated by the first heater 823 is blown out through the first air outlet 45C (not shown), and air heated by the second heater 824 is blown out through the fifth air outlet 45G (not shown).

[0168] In this way, the convection heater unit 82 circulates air in the heating chamber 4. Furthermore, the convection heater unit 82 uses the air blown from each air outlet to heat the object being heated.

[0169] In other embodiments, the microwave-based heating ratio, heating output, heater-based heating ratio, and energizing rate can be varied according to the degree of completion selected before the heating of the first and second foods begins.

[0170] Users can set the desired level of finish for the heated object via the control panel 5. For example, they can select between "High," "Standard," and "Low." Figure 9 Examples of heating ratio, heating output, and power consumption for the first and second food products, categorized by their respective completion levels, are shown below.

[0171] like Figure 9 As shown, the higher the completion level selected when choosing the first food item, the greater the proportion of time spent in the microwave heating process. For example, when the completion level is selected as "high," the proportion of time spent in the microwave heating process is 30%. When the completion level is selected as "standard," the proportion of time spent in the microwave heating process is 20%. When the completion level is selected as "weak," the proportion of time spent in the microwave heating process is 10%.

[0172] Furthermore, the higher the selected completion level, the greater the microwave heating output. For example, when the completion level is selected as "strong," the microwave heating output is 700W. When the completion level is selected as "standard," the microwave heating output is 600W. When the completion level is selected as "weak," the microwave heating output is 500W.

[0173] Furthermore, regarding the time ratio of the microwave heating process and the microwave heating output, as long as at least one of the microwave heating process time ratio and microwave heating output is as follows: Figure 9 Simply change it as shown.

[0174] like Figure 9As shown, the higher the completion level selected when choosing the first food item, the smaller the proportion of time spent in the heating process using the heater. For example, when the completion level is selected as "high," the proportion of time spent in the heating process using the heater is 70%. When the completion level is selected as "standard," the proportion of time spent in the heating process using the heater is 80%. When the completion level is selected as "weak," the proportion of time spent in the microwave heating process is 90%.

[0175] Furthermore, the higher the selected completion level, the greater the heater's energization rate. For example, when the completion level is selected as "strong," the heater's energization rate is 100%. When the completion level is selected as "standard," the heater's energization rate is 80%. When the completion level is selected as "weak," the heater's energization rate is 60%.

[0176] Furthermore, in the above embodiments, it was explained that the heater's energization rate is 100% when the completion level is selected as "strong," 80% when the completion level is selected as "standard," and 60% when the completion level is selected as "weak." However, the heater's output can also be varied to control energization based on the selected completion level. Specifically, the stronger the selected completion level, the stronger the heater's output becomes in order to control energization. For example, the heater's output could be set to 1000W when the completion level is selected as "strong," 800W when the completion level is selected as "standard," and 600W when the completion level is selected as "weak."

[0177] Furthermore, the time proportion and energizing rate of the heating process using the heater only need to be at least one of the following: Figure 4 Simply change it as shown.

[0178] like Figure 5 As shown, the higher the completion level selected when choosing the second food item, the greater the proportion of time spent in the microwave heating process. For example, when the completion level is selected as "high," the proportion of time spent in the microwave heating process is 50%. When the completion level is selected as "standard," the proportion of time spent in the microwave heating process is 40%. When the completion level is selected as "weak," the proportion of time spent in the microwave heating process is 30%.

[0179] Furthermore, the higher the selected completion level, the greater the microwave heating output. For example, when the completion level is selected as "strong," the microwave heating output is 700W. When the completion level is selected as "standard," the microwave heating output is 600W. When the completion level is selected as "weak," the microwave heating output is 500W.

[0180] Furthermore, regarding the time ratio of the microwave heating process and the microwave heating output, as long as at least one of the time ratio of the microwave heating process and the microwave heating output is as follows: ​ Simply change it as shown.

[0181] like ​ As shown, the higher the completion level selected when choosing the second food item, the smaller the proportion of time spent in the heating process using the heater. For example, when the completion level is selected as "high," the proportion of time spent in the heating process using the heater is 50%. When the completion level is selected as "standard," the proportion of time spent in the heating process using the heater is 60%. When the completion level is selected as "weak," the proportion of time spent in the microwave heating process is 70%.

[0182] Furthermore, the higher the selected completion level, the greater the heater's energization rate. For example, when the completion level is selected as "strong," the heater's energization rate is 100%. When the completion level is selected as "standard," the heater's energization rate is 80%. When the completion level is selected as "weak," the heater's energization rate is 60%.

[0183] Furthermore, in the above embodiments, it was explained that the heater's energization rate is 100% when the completion level is selected as "strong," 80% when the completion level is selected as "standard," and 60% when the completion level is selected as "weak." However, the heater's output can also be varied to control energization based on the selected completion level. Specifically, the stronger the selected completion level, the stronger the heater's output becomes in order to control energization. For example, the heater's output could be set to 1000W when the completion level is selected as "strong," 800W when the completion level is selected as "standard," and 600W when the completion level is selected as "weak."

[0184] Furthermore, the time proportion and energizing rate of the heating process using the heater only need to be at least one of the following: ​ Simply change it as shown.

[0185] Furthermore, the degree of completion of each heated object is distinguished as "strong," "standard," or "weak" based on the baking and browning speed of the heated object. For example, it can also be distinguished based on the weight of the heated object, the initial temperature, and the type of the heated object (mainly the attached material).

[0186] The above-described embodiment has a structure with microwave oven mode, grill mode, steam mode, and oven mode as heating modes. In other embodiments, as long as a grill mode is included as a heating mode, it is not necessary to have all five modes.

[0187] The control program 111 of the above-described embodiment can also be recorded in advance, non-temporarily, on a recording medium that can be read by the processor 100. The recording medium can be a magnetic, optical, or semiconductor memory device. Furthermore, the control program 111 can also be stored in advance in a server device or the like, and the above-described actions can be implemented by downloading the control program 111 from the server device using the heating device 1.

[0188] The processor 100 can consist of a single processor or multiple processors. The processor 100 can also be hardware programmed to implement corresponding functional units. That is, the processor 100 can be, for example, composed of an ASIC (Application Specific Integrated Circuit) or a FPGA (Field Programmable Gate Array).

[0189] ​ The structure of the heating device 1 shown is an example, and the specific installation method is not particularly limited. That is to say, it is not necessary to install hardware corresponding to each part separately; it is also possible to set up a structure in which the functions of each part are implemented by a processor executing a program. Furthermore, a part of the function implemented by software in the above embodiment can be implemented by hardware, or a part of the function implemented by hardware can be implemented by software.

[0190] ​ The steps shown are units divided according to the main processing content for ease of understanding of the action. The action is not limited by the method or name of the division of processing units. It can also be divided into more step units according to the processing content. Furthermore, it can be divided in a way that contains more processing in one step unit. Moreover, the order of these steps can be appropriately changed without affecting the spirit of this disclosure.

[0191] Furthermore, the above-described embodiments are used to illustrate the technology in this disclosure, and therefore, various changes, substitutions, additions, omissions, etc., can be made within the scope of the claims or their equivalents.

[0192] (Postscript)

[0193] The following technology has been disclosed through the above description of the embodiments.

[0194] (Technology 1) A heating apparatus comprising: a microwave heating unit that heats an object housed in a heating chamber using microwaves; a heater heating unit that heats the object using a heater; and a heating execution unit that controls the microwave heating unit and the heater heating unit to perform a heating process for heating the object, wherein, if the object to be heated is a first food product, the heating execution unit performs the heating process in such a manner that, in the first half of the heating process, heating based on the heater heating unit occupies more than half of the process time.

[0195] Therefore, in the first part of the heating process, the shape of the first food product can be firmly established by the heating of the heater, and the shape can be prevented from being distorted by water vapor generated from the inside using microwaves. Thus, heating suitable for the object being heated can be performed.

[0196] (Technology 2) A heating apparatus comprising: a microwave heating unit that heats an object housed in a heating chamber using microwaves; a heater heating unit that heats the object using a heater; and a heating execution unit that controls the microwave heating unit and the heater heating unit to perform a heating process for heating the object, wherein, if the object to be heated is a second food product, the heating execution unit performs the heating process in such a manner that, in the first half of the heating process, it accounts for more than half of the execution time of heating based on the microwave heating unit performed in the heating process.

[0197] Therefore, in the first half of the heating process, it is possible to ensure that the microwaves heat the second food for a longer period of time, raising the internal temperature of the food to generate steam before the outer surface is cooked. This allows for heating suitable for the object being heated.

[0198] (Technology 3) The heating apparatus according to Technology 1 or 2, wherein, as the final step in the heating process, the heating execution unit performs heating based on the heater heating unit.

[0199] This allows moisture adhering to the surface of the first food product to evaporate in the final process. Since heating of the heated food can be completed while suppressing moisture adhering to the surface, a heated food product with good taste can be provided after heating.

[0200] (Technology 4) The heating apparatus according to Technology 2, wherein the heating execution unit heats the object to be heated placed on a heating plate heated by microwaves in the heating process, and performs heating based on the microwave heating unit as the final step in the heating process.

[0201] Therefore, the surface of the second food item facing the heating plate can be baked and browned in the final process. This allows for heating suitable for the food being heated, and produces a high-quality food item with even browning after heating.

[0202] (Technology 5) A heating apparatus according to any one of Technologies 1 to 4, wherein the heating process includes: a first microwave heating process, wherein heating is performed using the microwave heating unit; and a second microwave heating process, wherein heating is performed using the microwave heating unit with a lower heating output than that of the first microwave heating process, wherein the heating execution unit performs heating based on the heater heating unit between the first microwave heating process and the second microwave heating process.

[0203] Therefore, in the second microwave heating process, since both the temperature of the heating plate and the temperature of the heated object are high, the bottom surface of the heated object is easy to bake and brown. However, by making the output of the second microwave heating process lower than that of the first microwave heating process, the baking and browning speed of the heated object is slowed down, which can reduce the possibility of overheating.

[0204] (Technology 6) A heating apparatus according to any one of Technologies 1 to 5, wherein the heating execution unit heats the object to be heated placed on a heating plate heated by microwaves in the heating process, and heating based on the microwave heating unit is performed in the first step of the heating process.

[0205] Therefore, microwaves can be used to efficiently heat the heating plate, and the object placed on the heating plate can be heated appropriately during the heating process.

[0206] (Technology 7) The heating device according to any one of Technology 1 to Technology 6, wherein the heating device includes an air supply section for supplying air to the heating chamber, and the heating execution section supplies air while heating with the heater heating section.

[0207] Therefore, the heat generated from the heating section of the heater can reach every corner of the heating chamber, suppressing uneven heating caused by the different positions of the heated object in the heating chamber. Thus, the heated object can be heated appropriately.

[0208] Furthermore, it can heat the entire surface of the object being heated using hot air, making it easier to prevent the object from losing its shape. Moreover, by using hot air to dry the surface of the object being heated, a crisp and delicious texture can be obtained.

[0209] (Technology 8) A heating apparatus according to any one of Technology 1 to Technology 7, wherein the heating apparatus includes a receiving unit that receives an additional heating execution instruction after the heating process is completed, and the heating execution unit performs heating based on the heater heating unit after the heating process is completed when the receiving unit receives the execution instruction.
