[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-223612 Summary of the Invention [Problem to be solved by the invention]

[0004] Cooking appliances sometimes use superheated steam, which is steam created by heating water to its boiling point and then further superheating the saturated steam that has turned into gas.

[0005] In Patent Document 1, a cup filled with water is placed in the heating chamber of a cooking device, and saturated steam is generated by microwave heating, but the generated saturated steam cannot be further superheated. In other words, Patent Document 1 does not allow cooking using superheated steam. Some cooking devices are equipped with a device that generates superheated steam, but this requires a boiler or the like to generate the superheated steam, which makes the cooking device more complex in structure and larger in size.

[0006] An object of the present invention is to provide a cooking device that is simple in configuration and capable of cooking with superheated steam while preventing the device from becoming too large. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the present invention provides a heating cooker comprising a main body having a heating chamber for storing an object to be heated, a water storage section for storing water, a heater heating section for heater-heating the object to be heated using a heater, a microwave heating section for microwave-heating the object to be heated using microwaves, an operation section which allows selection of any cooking menu from a plurality of cooking menus, and a control section which controls the heater heating section and the microwave heating section based on operation of the operation section, wherein when a cooking menu is selected from the operation section in which the object to be heated and the water storage section in which water is stored are placed in the heating chamber and cooked, the control section performs heater heating using the heater heating section for a predetermined time so that the temperature inside the heating chamber is higher than the boiling point of water, and after performing the heater heating, performs microwave heating using the microwave heating section for a predetermined time until the water in the water storage section reaches the boiling point, and after performing the microwave heating, performs heater heating using the heater heating section for a predetermined time.

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In principle, identical elements are designated by the same reference numerals in all drawings. Furthermore, descriptions of parts having identical functions will be omitted. Note that the configurations described below are merely examples, and it is not intended that the embodiments of the present invention be limited to the specific embodiments below.

[0010] In the following examples, as shown by the arrows in the figure, when viewed from the perspective of a user using the cooking appliance, the front side is defined as "front," the back side as "rear," the left-hand side as "left," the right-hand side as "right," the ceiling direction as "up," and the floor side as "down."

[0011] Fig. 1 is an external perspective view of a cooking device 1 according to an embodiment of the present invention. Fig. 2 is a cross-sectional view of the cooking device 1 of Fig. 1 cut along the front-to-rear direction. Fig. 3 is an external perspective view of the cooking device 1 showing the door in an open state. Fig. 4 is an external perspective view of the cooking device 1 in an open state when a table plate 27 is provided on a dish receiving shelf 16d. Fig. 5 is a control block diagram of the cooking device 1 according to an embodiment of the present invention.

[0012] The cooking appliance 1 comprises a main body 10 forming the outer shell, a door 11 that covers the front opening and can be opened and closed, a handle 12 attached to the front of the door 11 for opening and closing the door 11, an operation panel 13 provided below the front of the door 11, an operation unit 14 arranged on the operation panel 13 and used to start and stop cooking and to select any cooking menu from a plurality of cooking menus, and a display unit 15 arranged on the operation panel 13 for displaying the cooking menu selected by the operation unit 14, cooking time, etc.

[0013] Inside main body 10, there is formed a heating chamber 16 that stores the object to be heated (food), and a machine chamber 17 formed below heating chamber 16. Heating chamber 16 is covered by a door 11 that can be opened and closed. Door 11 is opened and closed to put the object to be heated into and take it out of heating chamber 16, and closing door 11 makes heating chamber 16 airtight, suppressing leakage of microwaves used to heat the object to be heated and containing heat from the heater and superheated steam, allowing for efficient heating.

[0014] Handle 12 is attached to door 11 and is shaped to be easy to grip, making it easy to open and close door 11. Door 11 is provided with a glass window 11a through which the state of the food to be heated stored inside heating chamber 16 during cooking can be checked.

[0015] In FIG. 2, the machine chamber 17 is provided in the space between the bottom surface 16b of the heating chamber and the bottom plate 10a of the main body 10, and is provided on the bottom plate 10a with a magnetron 18 for heating the object to be heated, a waveguide 19 connected to the magnetron 18, and a control unit 30 (not shown, see FIG. 5) for controlling the magnetron 18 and the heater heating unit 23 consisting of an upper heater 23a and a lower heater 23b.

[0016] Heating chamber bottom surface 16b has a recess in the approximate center, within which rotating antenna 20 is installed, and microwave energy radiated from magnetron 18 flows into the underside of rotating antenna 20 through waveguide 19 and opening 22a through which output shaft 21a of rotating antenna 20 passes, and is diffused by rotating antenna 20 before being radiated into heating chamber 16. Output shaft 21a of rotating antenna 20 is connected to rotating antenna driver 21.

[0017] An upper heater 23a constituting heater heating section 23 is attached to the back side of heating chamber top surface 16a of heating chamber 16 (above heating chamber 16), and a lower heater 23b constituting heater heating section 23 is attached below table plate 27 (below heating chamber 16). Upper heater 23a is formed into a flat shape by winding a heater wire around, for example, a mica plate and fixed by pressing it against the back side of the top surface of heating chamber 16, and heats the interior of heating chamber 16 from the top side of heating chamber 16 and bakes the heated objects stored therein by radiant heat. Similarly, lower heater 23b is formed into a flat shape by winding a heater wire around, for example, a mica plate and is disposed below table plate 27, and heats the interior of heating chamber 16 from the bottom side of heating chamber 16 and bakes the heated objects stored therein by radiant heat.

[0018] An internal temperature sensor 24 for detecting the internal temperature of the heating chamber 16 is provided on the rear side of the heating chamber top surface 16a of the heating chamber 16. An infrared sensor 25 for detecting the surface temperature of the object to be heated may also be provided.

[0019] A weight sensor 26 is provided on the bottom surface 16b of the heating chamber, and a table plate 27 is placed on top of the weight sensor 26. One or more weight sensors may be provided.

[0020] The table plate 27 is placed below the heating chamber 16 and is used to place the object to be heated. It is heat-resistant so that it can be used for both heater heating by the heater heating section 23 (upper heater 23a, lower heater 23b) and microwave heating in the microwave oven, and is made of a material such as ceramic that is transparent to microwaves.

[0021] In the cooking appliance 1 of this embodiment, the object to be heated is heated from below on the table plate 27 by microwave heating, and from above and below by the heater heating unit 23, thereby heating the object to be heated. At this time, the temperature measured inside the heating chamber 16 by the internal temperature sensor 24 or the like is reflected in the control. Smoke and steam generated when the object to be heated is cooked is exhausted to the outside of the main body 10 from the exhaust port 29 located on the rear right side of the main body 10.

[0022] The left and right side walls of the heating chamber 16 are provided with dish receiving shelves 16c and 16d of different heights, and the height of the table plate 27 can be changed by setting the table plate 27 on either of the dish receiving shelves 16c and 16d.

[0023] 5, the control unit 30 is provided with a calculation unit 31 that executes various calculation processes, and a memory unit 32 that stores control programs and the like for the calculation unit 31 to execute the calculation processes. The control unit 30 is also connected to the operation unit 14, the display unit 15, the internal temperature sensor 24, the timer 28, the infrared sensor 25, the weight sensor 26, the magnetron 18 and the rotary antenna driver 21 that constitute the microwave heating unit 40, and the upper heater 23a and the lower heater 23b that constitute the heater heating unit 23.

[0024] Cooking using superheated steam is sometimes performed in cooking appliances. Examples of cooking using superheated steam include non-fried "pork cutlet" and non-fried "fried chicken" from a frozen state. Generally, in order to generate superheated steam in the heating chamber 16, the cooking appliance needs to be equipped with a device such as a boiler, but the cooking appliance 1 of this embodiment is not equipped with a device such as a boiler. A means for generating superheated steam in the heating chamber to perform cooking in a cooking appliance not equipped with a device such as a boiler will be described below.

[0025] Fig. 6 is a top view of the table plate with a cup placed on it. Fig. 7 is a flowchart of cooking using superheated steam according to an embodiment of the present invention. Fig. 8 is a time chart showing the relationship between the heating state in the heating chamber and the temperature inside the oven according to an embodiment of the present invention. Fig. 9 is a diagram showing an example of a heating pattern when cooking non-fried "pork cutlet." Fig. 10 is a diagram showing an example of a heating pattern when cooking non-fried "fried chicken" from a frozen state.

[0026] To generate superheated steam within the heating chamber 16, in this embodiment, a small steam dish (hereinafter referred to as a cup 50) serving as a water reservoir is placed on the table plate 27 of the heating chamber 16. The cup 50 has a predetermined height to store a predetermined amount of water and is made of a material that is transparent to microwaves generated by microwave heating. The cup 50 may have any shape that can store water, and in this embodiment, it is rectangular. In this embodiment, the cup 50 is placed on the left rear of the table plate 27. This is to increase the distance from the exhaust port 29, which is located on the right rear of the main body 10. In other words, if the cup 50 is placed too close to the exhaust port 29, the steam generated from the cup 50 will be immediately sucked into the exhaust port 29, preventing the steam from being sufficiently diffused within the heating chamber 16. Therefore, when exhaust port 29 is located at the rear right (rear right side) of main body 10, cup 50 is preferably placed at either the rear left (rear left side), front right (front right side), or front left (front left side) of main body 10. In this embodiment, cup 50 is placed at the rear left side of cooking appliance 1 (main body 10), which makes it possible to prevent interference between cup 50 and the object to be heated when the object to be heated is placed in heating chamber 16 after cup 50 is placed on table plate 27.

[0027] When the cup 50 is placed on the front left side, the cup 50 is farther away from the exhaust port 29 located on the rear right side of the main body 10, and therefore the loss of water vapor generated from the cup 50 is reduced.

[0028] Furthermore, if the cup 50 is placed on either the front left or front right side, the user of the cooking appliance 1 can reduce the effort of carrying the cup 50 filled with water to the back of the heating chamber 16, improving usability. The table plate 27 may be provided with a guide so that the user can clearly identify where to place the cup 50.

[0029] When cooking using superheated steam in this embodiment, the cup 50 containing water is placed on the left rear of the table plate 27, and the food to be heated is placed in the center of the table plate 27. In this embodiment, the amount of water to be put in the cup 50 is, for example, 20 ml. The amount of water may also be different for each cooking menu. The amount of water required for cooking may also be displayed on the display unit 15. The cup 50 may also be marked with a scale or other markings in any way, such as by engraving, so that the user knows how much water to add.

[0030] 4, in this embodiment, even when the height of table plate 27 is changed, cup 50 is placed on table plate 27. If the height of table plate 27 is changed while cup 50 is placed on the interior bottom, steam generated from cup 50 toward food placed on table plate 27 is blocked by table plate 27. However, by placing cup 50 on table plate 27, the positional relationship between food and cup 50 can be kept constant.

[0031] Preparation for cooking using superheated steam is completed with the object to be heated and the cup 50 containing water placed on it. In this embodiment, the object to be heated, for example, non-fried "pork cutlet", is placed on the center of the table plate 27. Below, an example of the operation of the cooking device 1 when non-fried "pork cutlet" is selected as a cooking menu item will be described.

[0032] The user operates operation unit 14 to select an arbitrary cooking menu, non-fried "pork cutlet," from among multiple cooking menus. The non-fried "pork cutlet" cooking menu selected by operation unit 14 is a cooking menu in which an object to be heated (food) and a cup filled with water are placed in heating chamber 16 and cooked.

[0033] 7, when a heating instruction is received from operation unit 14 and cooking begins (step S700), control unit 30 starts energizing upper heater 23a and lower heater 23b in accordance with the control program stored in storage unit 32, and starts heating by heater heating unit 23 (step S701). One of the features of this embodiment is that heating by heater heating unit 23 begins first. If cup 50 containing water is not placed in heating chamber 16, if there is no water in cup 50, or if there is water in cup 50 but the amount of water is insufficient, control unit 30 may notify this fact using notification means such as display unit 15 or a speaker (not shown).

[0034] When heater heating unit 23 starts heating, control unit 30 activates timer 28 to count the elapsed time of heater heating and determines whether a predetermined time has elapsed (step S702). The predetermined time for heater heating varies depending on the type, weight, etc. of the object to be heated, so heating times corresponding to the type and weight of the object to be heated are pre-stored in memory unit 32. Calculation unit 31 determines the heating time for heater heating and the heating time for microwave heating from the cooking menu input from operation unit 14. Calculation unit 31 can also determine the heating time for heater heating and the heating time for microwave heating by further taking into account the weight of the object to be heated detected by weight sensor 26. Because a cup 50 containing water is placed on table plate 27, calculation unit 31 takes into account the weight of cup 50 containing water when detecting the weight of the object to be heated by weight sensor 26. In addition, in this embodiment, the weight sensor 26 is provided on the bottom surface 16b of the heating chamber, but by further providing it on the dish receiving shelves 16c and 16d, the heating time can be determined taking into account the weight of the heated object detected by the weight sensor 26 even if the height of the table plate 27 is changed.

[0035] 9, in the first step of heating by the heater heating unit 23, the control unit 30 sets the power supply rate to the upper heater 23a and the lower heater 23b to 100% and performs heater heating for a predetermined time of 420 seconds. The control unit 30 also sets the operating temperature of the heater heating unit 23 so that the temperature inside the heating chamber 16 is 150°C.

[0036] As shown in Figure 8, once heater heating starts, the temperature inside heating chamber 16 and the temperature of the water in cup 50 rise over time. Heating by heater heating unit 23 causes the temperature inside heating chamber 16 to rise rapidly, raising the temperature inside heating chamber 16 to 100°C or higher, which is higher than the boiling point of water. In this embodiment, control unit 30 sets and controls the heating time so that heater heating continues until the temperature inside heating chamber 16 reaches a temperature of 100°C or higher (for example, 120°C).

[0037] On the other hand, the temperature of the water in the cup 50 rises slowly. During the first step of heating with the heater, the temperature of the water in the cup 50 does not reach 100° C., so saturated steam is not generated in the heating chamber 16.

[0038] In this embodiment, cooking is performed by setting the heater heating time by the heater heating unit 23 in advance, but the heater heating time may also be set or changed based on the temperature inside the heating chamber 16 detected by the internal temperature sensor 24. For example, after performing a certain cooking, if the temperature inside the heating chamber 16 is sufficiently higher than room temperature, the heater heating time will reach the operating temperature in a time shorter than the set time. In this case, it is preferable that the control unit 30 change the heater heating time based on the temperature inside the heating chamber 16 detected by the internal temperature sensor 24. Furthermore, the sensor used for control is not limited to the internal temperature sensor 24, but an infrared sensor 25 or various other sensors provided in the cooking appliance 1 may also be used.

[0039] In FIG. 7, when the predetermined time has elapsed since the heater heating (Yes in step S702), the control unit 30 energizes the magnetron 18 and the rotary antenna driver 21 to start microwave heating, which is the second step (step S703). At this time, as shown in FIG. 8, the control unit 30 stops energizing the lower heater 23b (energization rate 0%), sets the microwave heating output to 250 W, and performs microwave heating for a predetermined time of 120 seconds. Note that in this embodiment, the microwave heating for cooking the non-fried pork cutlet also uses heating by the upper heater 23a. That is, in the second step of microwave heating, the upper heater 23a continues to be energized, while the lower heater 23b is deenergized. This is to remove moisture from the surface of the food to prevent moisture from coming out of the food during microwave heating, which would otherwise moisten the coating (breadcrumbs) on the surface of the food, impairing the texture.

[0040] If the predetermined time has not elapsed since the heater started heating (No in step S702), the control unit 30 continues heating by the heater.

[0041] As shown in Figure 8, when microwave heating begins, the temperature inside heating chamber 16 and the temperature of the water in cup 50 rise over time. During microwave heating, the temperature inside heating chamber 16 rises gradually. On the other hand, the temperature of the water in cup 50 rises rapidly. In this embodiment, cup 50 and table plate 27 are made of a material that transmits microwaves, so microwaves act on the water stored in cup 50 placed on table plate 27, and the temperature of the water in cup 50 rises rapidly to 100°C, which is the boiling point. When the temperature of the water in cup 50 reaches the boiling point, heating chamber 16 is filled with saturated steam that has turned into a gas.

[0042] In FIG. 7, when microwave heating starts, control unit 30 activates timer 28 to count the elapsed time of microwave heating, and determines whether or not a predetermined time has elapsed since microwave heating (step S704).

[0043] If the predetermined time has elapsed since the microwave heating (Yes in step S704), the control unit 30 stops the power supply to the magnetron 18 and the rotary antenna driver 21, and starts the heater heating, which is the third step (step S705). In the heater heating in step S705, as shown in FIG. 8, the power supply rate to the lower heater 23b is set to 72%, and heater heating is performed together with the upper heater 23a for a predetermined time of 838 seconds.

[0044] If the predetermined time has not elapsed since the microwave heating (No in step S704), the control unit 30 continues the microwave heating.

[0045] 8, once the heater starts heating, the temperature inside heating chamber 16 gradually rises over time. Meanwhile, the temperature of the water in cup 50 remains at 100°C, which is the boiling point, and heating chamber 16 continues to be filled with saturated steam.

[0046] In the heater heating in step S705, the heating chamber 16 is filled with gaseous saturated steam, and since the temperature inside the chamber exceeds 100° C., the gaseous saturated steam is superheated to become superheated steam. Then, the non-fried "pork cutlet" is cooked using this superheated steam.

[0047] In FIG. 7, when the heater heating starts, the control unit 30 starts the timer 28 to count the elapsed time of the heater heating, and determines whether the heater heating has continued for a predetermined time (step S706).

[0048] If the heater heating has continued for a predetermined time (Yes in step S706), the control unit 30 stops the supply of electricity to the upper heater 23a and the lower heater 23b, and ends the cooking process (step S707). After cooking is complete, the cup 50 is hot, so it is preferable to warn the user not to touch the cup 50. Therefore, after cooking is complete, the control unit 30 may notify the user that the cup 50 is hot through notification means such as the display unit 15 or a speaker (not shown).

[0049] If the predetermined time has not elapsed since the heater started heating (No in step S706), the control unit 30 continues heating by the heater.

[0050] In the microwave heating in the cooking process for the non-fried "pork cutlet" described above, the upper heater 23a is used in addition to the microwave heating, but heating by microwaves alone may be used depending on the cooking menu.

[0051] Next, an example of the operation of the cooking device 1 when non-fried "fried chicken" is selected as a cooking menu item will be described.

[0052] For example, when cooking non-fried "fried chicken" from a frozen state as shown in Fig. 10, in order to quickly raise the temperature inside heating chamber 16, in the first heater heating step, control unit 30 sets the power supply rate to upper heater 23a and lower heater 23b to 100% and performs heater heating for a predetermined time of 420 seconds. Control unit 30 also sets the operating temperature of heater heating unit 23 so that the temperature inside heating chamber 16 becomes 180°C.

[0053] As in the case where non-fried "pork cutlet" is selected as the cooking menu, the control unit 30 sets and controls the heating time so that the heater heats the food until the temperature inside the heating chamber 16 reaches 100°C or higher.

[0054] During microwave heating, the control unit 30 does not energize the upper heater 23a and the lower heater 23b, sets the microwave output to 600 W, and performs heating using only microwaves for 180 seconds.

[0055] Furthermore, the heater heating is performed for a predetermined time of 1050 seconds with the upper heater 23a energized at 87.5% and the lower heater 23b energized at 25%. During this heater heating, the interior of the heating chamber 16 is filled with saturated steam that has turned into gas, so the saturated steam is superheated to become superheated steam. This allows the non-fried "fried chicken" to be cooked.

[0056] In this embodiment, when switching between the first, second, and third steps, the process moves to the next step after each step is completed, but the process may move to the next step without waiting for each step to be completed. For example, the process may be switched by gradually reducing the heater output for the heater heating in the first step and gradually increasing the microwave heating output in the second step.

[0057] As described above, according to this embodiment, a small steam dish (cup) serving as a water reservoir is placed inside the heating chamber, and after heating with the heater, superheated steam is generated by combining microwave heating and heater heating, which eliminates the need for a mechanism for generating superheated steam such as a boiler and prevents the cooker from becoming larger. Furthermore, since the effort required for maintaining mechanisms such as a boiler is eliminated, users can more easily cook using superheated steam.

[0058] The present invention is not limited to the above-described embodiments and includes various modifications. For example, the above-described embodiments have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those including all of the described configurations. Furthermore, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment, or to add the configuration of another embodiment to the configuration of one embodiment. Furthermore, it is possible to add, delete, or replace part of the configuration of each embodiment with other configurations. [Explanation of symbols]
