Description

[Technical Field]

[0001] The present disclosure relates to a cooking device that heats an object to be heated, such as a pot placed on a top plate, and a cooking system that uses the cooking device. [Background technology]

[0002] Cooking appliances can be broadly divided into three types based on the environment in which they are used. One of these is the so-called "built-in type," which is installed inside kitchen furniture such as a kitchen counter. The second is the "freestanding type," which is placed in a designated location on kitchen furniture, like a gas stove (also called a "gas-fired table"). The third is the small, portable "tabletop type," which is placed in any desired location on a dining table, etc.

[0003] Many "built-in" cooking appliances are equipped with multiple heat sources and are popular for their ability to handle a variety of cooking methods. However, because they are installed inside kitchen furniture, the external dimensions must be designed to conform to the standards of general kitchen furniture, meaning there is significantly less freedom in design compared to "freestanding" or "tabletop" appliances, making it difficult to create a practical product.

[0004] A typical heating cooker that can expand the range of cooking options has been proposed, which has a grill chamber (also called an "oven chamber" or "heating chamber," but hereinafter referred to collectively as "heating chamber") inside the main body that is heated by a heat source, and which introduces microwaves from a microwave heating source into the heating chamber (see Patent Document 1).

[0005] The cooking device disclosed in Patent Document 1 can employ a cooking method in which heating is performed in both the upper part of the top plate (first location) and the inner space of the heating chamber (second location), so that the heating means and the heating space (environment) can be changed to accommodate a variety of foods. In particular, when a specific food (e.g., hamburger steak) is selected, it is convenient if one cooking condition data set includes the heating means and the heating space (environment).

[0006] Meanwhile, a cooking system has been proposed in the past in which communication is performed between a communication terminal such as a smartphone and a cooking appliance, and cooking condition data corresponding to a cooking recipe selected on the communication terminal is transmitted from the communication terminal to the cooking appliance to perform automatic cooking (see, for example, Patent Documents 2 and 3).

[0007] Patent document 2 describes a configuration in which, in a cooking appliance (gas-fired cooking appliance) equipped with multiple heating sections (e.g., right burner, left burner, rear burner) and communication functions, when a user operates a communication terminal to select a specific recipe from a cooking menu, the cooking appliance acquires cooking condition data for the multiple heating sections all at once.

[0008] Furthermore, Patent Document 3 discloses a proposal that allows the cooking appliance to select the heating section to be used from among a plurality of heating sections (for example, a right burner and a left burner). The heating cooker of Patent Document 3 is equipped with a recipe information allocation unit that automatically allocates cooking condition data (information) to each of the multiple heating units when the heating units acquire pre-specified cooking condition data from a communication terminal. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2020-87506 A (page 20, FIG. 18) [Patent Document 2] Japanese Patent Application Laid-Open No. 2017-106685 [Patent Document 3] Japanese Patent Application Laid-Open No. 2017-106679 Summary of the Invention [Problem to be solved by the invention]

[0010] Even if the technology described in Patent Document 2 or 3 is directly applied to a cooking device such as that described in Patent Document 1, there are significant problems in actual use. For example, in the cooking device of Patent Document 1, if a cooking method is considered in which an induction heating source is driven to perform cooking step 1, and then a microwave heating source is driven to perform cooking step 2 in a heating chamber, it is necessary to coordinate the operations of specific heating units among multiple heating units (located in different locations) so that they can be driven in a specified order. There is also a concern that if cooking condition data (also called "recipe data") is acquired carelessly, it may cause confusion for the user or result in the user having to manually cancel or correct the data, which is a new and cumbersome task.

[0011] Furthermore, particularly in a cooking device equipped with a plurality of heating means, it is necessary to ensure reliable control on the cooking device side, taking into consideration the timing of receiving cooking condition data from the outside via wireless communication.

[0027] The cooking device and cooking system according to the present disclosure will be described below with reference to the drawings. In the following description, terms indicating directions (e.g., "up," "down," "right," "left," "front," "rear," etc.) are used to facilitate understanding, but these are for explanatory purposes only. In addition, in each drawing, items with the same reference numerals are the same or equivalent, and this applies throughout the entire specification.

[0028] In the following explanation, when we say "a heated object placed on the top plate," it means both cases where a heated object such as a pot is placed directly on the top surface of the top plate 3 described below and heated, and cases where a heated object is placed on a support member such as a trivet arranged above the top plate, such as a gas burner, and heated.

[0029] In this first embodiment, the "second heating means" HM2 refers to a heat source for heating food placed inside the heating chamber 6, which will be described later. The second heating means may be a steam generator (boiler) that supplies high-temperature steam (such as superheated steam).

[0030] In the first embodiment, a magnetron is used as the microwave heating source, but there is no limitation on the microwave oscillation principle or method, such as a microwave oscillator, etc. Also, a plurality of heating sources may be provided.

[0031] In this first embodiment, the "third heating means" HM3 is called "third" to indicate the difference from the second heating means HM2, but does not imply a superiority or inferiority relationship. In addition, in embodiment 1, a heat source using a radiant electric heat source (sheath heater, mica heater, carbon heater, ceramic heater, infrared heater, radiant heater, etc.) is used, but a heat source that generates heat in other forms or methods may also be used.

[0032] The third heating means HM3 is capable of cooking in one heating chamber 6. It may be configured to use multiple heating sources with different heating principles in combination, such as a heating source made up of an electric heater and a gas combustor (burner). An induction heating source may also be used as the heating source for heating the heating chamber 6. A steam generator (boiler) that supplies high-temperature steam (such as superheated steam) may also be used.

[0033] Furthermore, the third heating means may be either a heat source that heats the wall surface of the heating chamber 6 from the outside, or a heat source that is installed in the internal space of the heating chamber 6 and heats the atmosphere in the internal space to a high temperature. In addition, a heat-generating element that becomes hot by induction heating may be placed in the heating chamber, and this heat-generating element may heat the wall surface of the heating chamber 6 from the outside, or may heat the air inside the heating chamber 6.

[0034] A typical example of the induction heating coil (IH coil) referred to in this first embodiment is one made by bundling about 30 thin copper or aluminum wires of about 0.1 mm to 0.3 mm, twisting several of these bundles together, and winding them into a spiral. Another example is one made by winding about 1,000 to 1,500 wires of about 0.05 mm. Another proposal is to use a ring-shaped conductor made of a flat conductive material. Any of these forms corresponds to the "IH coil" which is the main part of the induction heating source 9.

[0035] In this embodiment 1, "coordinated cooking" refers to cooking using two or more heating sources that heat one item (including food, meat, vegetables, etc.) in different locations and whose heating operation conditions can be set independently.

[0036] The "coordinated cooking" mentioned above refers to the use of multiple heating means with a time lag. For example, in the process of completing a single cooking step, after preheating with a microwave heating source, the food to be cooked is moved to another location, and then heated with an induction coil at the new location to complete the cooking, which is a type of "coordinated cooking" as defined here.

[0037] Another type of "cooperative cooking" is to heat the food to be cooked inside the heating chamber 6 using a gas burner (burner), and then move the food to the top plate 3 and heat it using the gas burner (burner) or induction heating source 9 to improve the cooking quality.

[0038] Embodiment 1 (1. Configuration of the cooking system) The first embodiment of the present disclosure is shown in FIGS. Referring to FIG. The cooking system of the present embodiment 1 is configured to include a cooking appliance 1 and a smartphone 200 (corresponding to a communication terminal) having a function of performing wireless communication with the cooking appliance 1. The communication terminal may be a tablet terminal with a communication function, a personal computer, or the like, other than the smartphone 200.

[0039] The smartphone 200 performs wireless communication using WiFi (registered trademark) or the like with a wireless router (not shown) installed in a house (not shown) in which the cooking appliance 1 is used.

[0040] The cooking appliance 1 can acquire at least the cooking condition data CD2 through wireless communication 400 with the smartphone 200. The cooking condition data CD2 will be described later. The smartphone 200 performs wireless communication 400 with the cooking appliance 1 using Bluetooth (registered trademark) or the like.

[0041] The smartphone 200 accesses the cloud server 300 in an external space via the wireless router 340 (not shown) and a network 201 such as the Internet. The cloud server 300 has at least one recipe information providing server 301.

[0042] The recipe information providing server 301 is equipped with a recipe DB (database) 302 that stores data on various cooking recipes, and the smartphone 200 accesses a recipe providing site operated by the recipe information providing server 301 and acquires (downloads) various cooking condition data CD1 from the recipe DB 302.

[0043] The cooking condition data CD1 and CD2 are also called recipe data. As will be explained in detail later, the cooking condition data CD1 and CD2 contain commands (command data) that specify heating means and control conditions (including, but not limited to, at least one of heating power and heating time) so that a specific food can be cooked in the cooking appliance 1.

[0044] The cooking device 1 shown in Figure 1 comprises a first heating means HM1 arranged below a top plate 3 (described in Figure 4 and subsequent figures) covering the upper surface of the cooking device 1, a second heating means HM2 that supplies microwaves to a heating chamber 6 (see Figure 5) formed inside the cooking device 1, and a third heating means HM3 that is located inside or outside the heating chamber 6 and raises the temperature of the internal space of the heating chamber 6 to heat it.

[0045] If the upper surface of the top plate 3 is defined as a "first location," then induction heating means is used as the first heating means HM1 to heat an object to be heated (a magnetic metal pot) placed in this first location. Alternatively, a gas combustion device equipped with a gas burner can be used as the first heating means HM1.

[0046] If a closed space located away from the first place is defined as a "second place," then the inside of the heating chamber 6 (see FIG. 5) is the second place.

[0047] The cooking device 1 has a function of executing an "independent cooking mode" KM1 in which the first heating means HM1 and the second heating means HM2 are driven independently (independently).

[0048] The cooking appliance 1 has a function of executing a "combined cooking mode" KM2, which is a method of cooking one food item by simultaneously driving the second heating means HM2 and the third heating means HM3, or by starting one of them first and then automatically driving the other. Even when the second heating means HM2 and the third heating means HM3 are operating simultaneously, whether the heating ends at the same time or at different times is one type of operation pattern of the "combined cooking mode" KM2.

[0049] The "combined cooking mode" KM2 has at least the following patterns: a pattern in which the second heating means HM2 and the third heating means HM3 are driven simultaneously from the beginning (RG control mode 1), a pattern in which the third heating means HM3 starts to be driven after the second heating means HM2 (RG control mode 2), and a pattern in which the third heating means HM3 is driven first and then automatically switched to the second heating means HM3 (RG control mode 3). In these RG control modes 1 to 3, switching between the heating means is automatically performed when cooking begins in the heating chamber 6 (see FIG. 5).

[0050] Unlike the linked cooking mode KM3, the "combined cooking mode" KM2 does not have a cooking menu corresponding to a specific food item (e.g., hamburger steak). That is, it provides a "control menu" for each pattern for driving the second heating means HM2 and the third heating means HM3.

[0051] For example, one of the "control menus" is the "RG control mode 1." In the RG control mode (RG composite cooking mode), various foods can be cooked. One of the "control menus," for example, the "RG control mode 1," is controlled by cooking condition data that defines the control mode, but is not set for each specific food to be cooked.

[0052] In other words, the operation pattern in which two or more heating sources (the second heating means HM2 and the third heating means HM3) are operated in a predetermined sequence is the composite cooking mode KM2 having multiple "control menus."

[0053] In contrast to this, the cooperative cooking mode KM3 with a cooperative cooking menu applies multiple cooking condition data (corresponding to specific foods) to heat and cook foods placed inside the heating chamber 6 and above the top plate 3 in a predetermined order. That is, the contents of the cooking condition data are different between the composite cooking mode KM2 and the cooperative cooking mode KM3.

[0054] The cooking appliance 1 has a function of executing a "cooperative cooking mode" KM3 in which the first heating means HM1 and the second heating means HM2 are driven with a time difference determined depending on the operation of the user.

[0055] The "combined cooking mode" KM3 has a pattern in which cooking step 1 is performed by the first heating means HM1, and a pattern in which cooking step 1 is performed by the second heating means HM2. For example, to move on to cooking process 2 after completing cooking process 1 using the first heating means HM1, the food to be cooked is moved into the heating chamber 6, and then the second heating means HM2 begins to operate, so there is a rest period between cooking process 1 and cooking process 2 during which no heating operation is performed.

[0056] In this "cooperative cooking mode" KM3, the control condition data (recipe data) is prepared for each specific food to be cooked (for example, hamburger steak, roast beef, or gratin). The control condition data (recipe data) specifies the heating means to be used, the order in which the heating means are driven, and the control conditions of the heating means (including at least one of heating power, heating time, etc., but not limited to these).

[0057] The control condition data (recipe data) is stored in both the cooking appliance 1 and the recipe DB 302. The control condition data (recipe data) stored in the recipe DB and the cooking appliance 1 do not need to be the same. For example, the recipe DB 302 may be configured such that control condition data for a new cooperative cooking mode KM3 is sequentially added, and the control condition data (recipe data) for a composite cooking menu is sequentially accumulated.

[0058] When the cooking appliance 1 acquires the cooking condition data for executing the cooperative cooking mode KM3 from the smartphone 200, the data is for one cooking menu unit selected by the user on the smartphone 200. This is not limited to the "cooperative cooking mode" KM3, but is also common to the "combined cooking mode" KM2 and the "single cooking mode."

[0059] As described above, the smartphone 200 requests the recipe information providing server 301 to provide a recipe for a desired food to be cooked, and downloads the cooking condition data CD1 corresponding to the desired recipe.

[0060] The smartphone 200 can transmit cooking condition data CD2 corresponding to the recipe acquired from the recipe information providing server 301 to the cooker 1. To use this recipe acquisition function, the user of the cooking appliance 1 accesses the recipe providing site (recipe information providing server 301) and installs an application for selecting recipes (hereinafter referred to as recipe selection app) on the smartphone 200.

[0061] When the user installs the recipe selection app, the user performs an operation to register identification information such as the model name of the cooking appliance as an initial setting. This registration allows the user to obtain cooking condition data corresponding to the specifications of the cooking appliance 1 (such as the heating capacity of each of the heating means HM1 to HM3) from the recipe providing site (recipe information providing server 301).

[0062] Furthermore, the user uses the recipe selection app to pair the smartphone 200 with the cooking appliance 1, thereby establishing wireless communication 400 between the smartphone 200 and the cooking appliance 1. Note that this wireless communication may use a near field communication (NFC) method.

[0063] Next, we will explain Figure 2. The cooking system in Figure 2 differs from that shown in Figure 1 in the role of the smartphone 200. Another difference is that it is the cooker 1, not the smartphone 200, that accesses the recipe providing site (recipe information providing server 301) and obtains an application for selecting a recipe (hereinafter referred to as "recipe selection app").

[0064] The smartphone 200 and the recipe providing site (recipe information providing server 301) are connected via a network 202 such as the Internet. The recipe providing site (recipe information providing server 301) and the cooking appliance 1 are connected via a network 203 such as an internet line. A wireless router (not shown) may be interposed between the smartphone 200 and the cloud server 300. Similarly, a wireless router (not shown) may be interposed between the cooking appliance 1 and the cloud server 300.

[0065] 2, cooking condition data CD3 (corresponding to a recipe) created by the user can be sent to the recipe providing site (recipe information providing server 301) using smartphone 200, temporarily stored in the recipe DB 302, and provided to cooker 1. In other words, if smartphone 200 is located far away from the house in which cooker 1 is installed (for example, while away from home), cooking condition data CD3 of smartphone 200 can be conveniently stored in recipe information providing server 301.

[0066] The cooking appliance 1 downloads cooking condition data CD4 corresponding to a specific recipe stored in the recipe information providing server 301 via the network 203 between the cooking appliance 1 and the recipe providing site (recipe information providing server 301). In this case, the cooking condition data CD4 may be the cooking condition data CD2 provided by the smartphone 200.

[0067] In order to use the function of (directly) obtaining information from recipe data (cooking condition data), the user of the cooking appliance 1 accesses the recipe providing site (recipe information providing server 301) and installs the "recipe selection application" in advance on the cooking appliance 1. It is convenient if this installation can be easily performed on the cooking appliance 1 as one menu of the "function mode" described later.

[0068] When the user installs the recipe selection app, the user performs an operation to register identification information such as the model name of the cooking appliance as an initial setting. This registration allows the user to obtain cooking condition data corresponding to the specifications of the cooking appliance 1 (such as the heating capacity of each of the heating means HM1 to HM3) from the recipe providing site (recipe information providing server 301).

[0069] In the heating and cooking system of Figure 2, the user can obtain cooking condition data CD1 (corresponding to a recipe) as described in Figure 1, display and check the contents of the cooking condition data CD1 on the display screen of the smartphone 200, and then modify part of the cooking condition data CD1 as cooking condition data CD3 and store it in the recipe providing site (recipe information providing server 301) as described in Figure 2.

[0070] In the cooking system shown in Figure 1, when the smartphone 200 and the cooking appliance 1 are located close to each other, cooking condition data CD2 can be provided from the smartphone 200 to the cooking appliance 1. However, for example, when the smartphone 200 is taken to a remote outdoor location, the cooking appliance 1 cannot directly acquire the cooking condition data CD2. In contrast, in the cooking system shown in Figure 2, regardless of the location of the smartphone 200, as long as the recipe providing site (recipe information providing server 301) can be accessed, the cooking condition data CD4 can be downloaded and used for cooking.

[0071] Next, FIG. 3 will be described. The cooking system shown in FIG. 3 differs from that shown in FIG. 1 in the role of the recipe providing site (recipe information providing server 301). In the cooking system of FIG. 3, the cooker 1 accesses the recipe providing site (recipe information providing server 301) and downloads cooking condition data CD6.

[0072] In addition, in the cooking system of FIG. 3, the cooker 1 can access a recipe providing site (recipe information providing server 301) and provide cooking condition data CD7. For example, if cooking is actually performed and the cooking is satisfactory, after the cooking, the cooking condition data remaining in the storage unit of the cooker 1 can be provided to the recipe providing site (recipe information providing server 301) as improved cooking condition data CD7. Such favorite recipes of the user can be registered (stored) in the recipe information providing server 301 as "favorite recipes." Note that this system differs from the cooking system of FIG. 1 in that it is the cooker 1 that acquires the application for selecting a recipe (referred to as a "recipe selection app").

[0073] The cooking appliance 1 and the recipe providing site (recipe information providing server 301) are connected via networks 204 and 205 such as the Internet. A wireless router (not shown) may be interposed between the cooking appliance 1 and the cloud server 300. Similarly, a wireless router (not shown) may be interposed between the networks 204, 205 between the cooking appliance 1 and the cloud server 300. A wireless router (not shown) may also be interposed between the smartphone 200 and the cloud server 300.

[0074] 3, a user can obtain cooking condition data CD6 directly from a recipe providing site (recipe information providing server 301) using cooker 1. Therefore, even if the user does not own smartphone 200, the user can obtain cooking condition data CD6 for a desired recipe from the recipe providing site (recipe information providing server 301) every time cooking is performed. Furthermore, as described above, if the cooking is actually performed and the cooking is satisfactory, the cooking condition data CD7 can be provided to the recipe providing site (recipe information providing server 301) after the cooking is performed as improved cooking condition data CD7. Therefore, from the next time onwards, the cooking condition data CD7 can be called up from the cooking appliance 1 and used for cooking, which is convenient.

[0075] (2. Configuration of the cooking device) Next, the configuration of the cooking device 1 will be described with reference to FIGS. 4 and 5, cooking appliance 1 is a built-in IH cooking heater that is incorporated into kitchen furniture 600 that has a cooking table on top. Cooking appliance 1 has a main body 2 and a top plate 3 that is installed on main body 2. Top plate 3 is exposed above a kitchen countertop that forms the top surface of kitchen furniture 600.

[0076] The top plate 3 is composed of, for example, a heat-resistant glass plate and a metal frame attached around the periphery of the glass plate. Three heating ports 4, namely, a left heating port 4L, a right heating port 4R, and a center heating port 4C, are provided on the upper surface of the top plate 3.

[0077] The left heating port 4L, the right heating port 4R, and the central heating port 4C indicate areas where metal cooking containers such as pots or frying pans (also referred to as "heated objects" for the first heating means HM1) are placed. Guide marks (not shown) that serve as guides for placing the heated objects on the left heating port 4L, the right heating port 4R, and the central heating port 4C are printed on the upper surface of the top plate 3.

[0078] An exhaust port cover 5 is provided on the far side (rear side) of the top plate 3. The exhaust port cover 5 is made of a punched metal or lattice-shaped metal member with numerous small through-holes, and is breathable throughout with little air resistance. Exhaust air released from inside the cooking appliance 1 passes through the exhaust port cover 5 and exits to the outside of the cooking appliance 1.

[0079] A door (heating door) 7 is provided on the front of the main body 2 of the cooking appliance 1, for opening and closing the front of the heating chamber 6 (see FIG. 5) arranged inside the main body 2. The door 7 is provided with a handle 8 for opening and closing the door.

[0080] Fig. 5 is a schematic vertical cross-sectional view of the cooking device 1 according to embodiment 1 as seen from the side. As shown in Fig. 5, an induction heating coil 9L (hereinafter referred to as "left IH coil") serving as left induction heating means is provided below the left heating port 4L.

[0081] Similarly, an induction heating coil 9R (hereinafter referred to as the "right IH coil") is provided below the right heating port 4R as a right induction heating means, and an induction heating coil 9C (hereinafter referred to as the "central IH coil") is provided below the central heating port 4C as a central induction heating means.

[0082] These IH coils 9C, 9L, and 9R are circular heating coils made of wound thin conductors such as copper or aluminum wire, and generate a high-frequency magnetic field when a high-frequency current is supplied to them, which inductively heats the cooking vessels (objects to be heated) placed over the left heating port 4L, right heating port 4R, and center heating port 4C.

[0083] The heating means including the IH coils 9C, 9L, and 9R and their drive circuits (high-frequency power supply circuits such as inverter circuits, not shown) may be referred to as the induction heating source 9 or first heating means HM1. In the following description, the term "first heating means" HM1 will be used unless there is a particular contradiction.

[0084] A temperature sensor group 30 (not shown) consisting of multiple temperature sensors is mounted near the IH coils 9C, 9L, and 9R to detect the temperatures of the top plate 3 and cooking vessel (heated object). One temperature sensor 30A (not shown) constitutes one sensor in the temperature sensor group 30 shown in FIG.

[0085] The heating chamber 6 is provided inside the main body 2 and below the IH coils 9C, 9L, and 9R. The heating chamber 6 is surrounded by a metal wall such as stainless steel, and is a space for heating the food (foodstuffs, ingredients) contained within the heating chamber 6.

[0086] The food to be cooked may be placed on a heat-resistant plastic container, a porcelain or heat-resistant glass dish, or may be placed inside a container and placed in the heating chamber 6. In such cases, the dish or container may be called a "heated container." However, because the container is not induction-heated by the IH coils 9C, 9L, and 9R, even if it is placed on the heating port 4 of the top plate 3, it is not called an "food to be heated" for the IH coils 9C, 9L, and 9R.

[0087] An opening is formed in the front of the heating chamber 6 for putting in and taking out the food to be cooked. The opening in the front of the heating chamber 6 is covered by a door 7 that can be opened and closed freely. The door 7 is supported by the main body 2 so as to be rotatable via a hinge and an arm (not shown). This allows the door 7 to open forward to a horizontal position with its lower end as a fulcrum (center of rotation). The door 7 may be pulled forward integrally with a support member (a structure such as a shelf, not shown) that supports the container to be heated from below, by a slide rail (not shown).

[0088] Door 7 is provided with an open / close detector 10 for detecting whether door 7 is open or closed. Open / close detector 10 is, for example, a microswitch or an infrared sensor. A microwave oscillator 11 is provided behind heating chamber 6 to heat the food placed in heating chamber 6. Microwave oscillator 11 is, for example, made up of a magnetron, and irradiates microwaves into heating chamber 6 to heat the food placed in the heating chamber, i.e., perform so-called range heating.

[0089] The heating means including the microwave oscillator 11 and its drive circuit (which refers to a high frequency power supply circuit such as an inverter circuit, not shown) may be called second heating means HM2.

[0090] Additionally, upper radiant heat heating means 12a and lower radiant heat heating means 12b are provided in heating chamber 6 to heat the food from above and below using so-called heaters. Upper radiant heat heating means 12a is located on the outer or inner ceiling wall surface of heating chamber 6, and lower radiant heat heating means 12b is located on the inner or outer wall surface of heating chamber 6, and both are sheath heaters.

[0091] Other types of radiant heat heating means (for example, a mica heater or a carbon heater) may be installed outside the heating chamber 6. Figure 5 shows an example in which the upper radiant heat heating means 12a and the lower radiant heat heating means 12b are both installed in close contact with the outer wall surface of the heating chamber 6.

[0092] The heating means including the upper radiant heat heating means 12a and the lower radiant heat heating means 12b and their drive circuits (not shown) may be referred to as the third heating means HM3. The upper radiant heat heating means 12a and the lower radiant heat heating means 12b may be collectively referred to as the "radiant heat heating means," in which case the reference numeral "12" is used.

[0093] Additionally, heating chamber 6 is provided with infrared sensor 13, a non-contact temperature sensor, for detecting the temperature of the food inside heating chamber 6 without contact. The temperature range detected by infrared sensor 13 is set to, for example, -20°C to 100°C. This allows the degree of heating of the food to be detected accurately in real time, for example, in 1°C increments. Infrared sensor 13 also constitutes one sensor in the group of temperature sensors 30 shown in FIG. 11.

[0094] The heating chamber 6 is also provided with a contact temperature sensor (for example, a thermistor sensor) 14, which is an interior temperature sensor that detects the atmospheric temperature inside the heating chamber 6 or the wall temperature of the heating chamber 6.

[0095] The thermistor sensor 14 detects temperature by detecting changes in electrical resistance, and therefore the upper limit of the temperature that can be detected is approximately 250° C. This thermistor sensor 14 also constitutes one sensor in the group of temperature sensors 30 shown in Fig. 10. Note that this thermistor sensor 14 may be installed in two locations, near the bottom and near the ceiling of the heating chamber 6, as shown in Fig. 5.

[0096] Fig. 6 is a top view of the cooking appliance 1 according to embodiment 1. As shown in Fig. 6, a left operating unit 15L, a central operating unit 15M, and a right operating unit 15R are provided on the front side of the upper surface of the top plate 3 of the cooking appliance 1. These three operating units may be collectively referred to as "input operating units," and in that case the reference numeral 15 is used.

[0097] At the rear (rear side) of the left operating unit 15L, the central operating unit 15M and the right operating unit 15R, there are provided a left display unit 16L, a central display unit 16M and a right display unit 16R, a left heating power display unit 17L and a right heating power display unit 17R and a central heating status display unit 17M.

[0098] The left display unit 16L, the center display unit 16M, and the right display unit 16R may be collectively referred to as the "display unit," in which case the reference numeral 16 is used. The center display unit 16M has a horizontally long liquid crystal display screen.

[0099] The left heating power display unit 17L and the right heating power display unit 17R display the heating power level using light-emitting elements (LEDs, etc.), and do not have a display screen.

[0100] The left heating power display unit 17L, the right heating power display unit 17R, and the center heating status display unit 17M may be collectively referred to as the "heat power display units," in which case the reference numeral 17 is used.

[0101] Also, adjacent to the right operation unit 15R, there is provided an operation button (key) 20A for a main power switch 20 (see FIG. 11). The main power switch 20 turns on or off the main power supply of the cooking appliance 1. The button (key) that is pressed to turn the power on or off is the operation button 20A.

[0102] When the main power supply of the cooking appliance 1 is OFF, pressing the operation button 20A for a few seconds, for example, turns the main power supply ON. When the main power supply of the cooking appliance 1 is ON, pressing the operation button 20A for a few seconds, for example, turns the main power supply OFF.

[0103] 7 is an enlarged view of left display unit 16L, left heating power display unit 17L, and left operation unit 15L according to embodiment 1. Left display unit 16L displays information related to cooking using left heating port 4L, and is implemented, for example, by a liquid crystal display.

[0104] The left display unit 16L displays the set time for timer cooking for the heated object placed on the left heating port 4L, the elapsed time since the heating operation at the left heating port 4L started, or the remaining time until the timer set time ends.

[0105] When preheat cooking is selected for the left heating port 4L, the left display unit 16L displays the automatically set temperature (default temperature) or the current temperature. The automatically set temperature (default temperature) refers to the target temperature of the bottom of an object to be heated (e.g., a metal pot) when the object is heated using the left heating port 4L. The default temperature can be changed by the user within a certain range.

[0106] The left heating power display unit 17L is composed of multiple light-emitting elements (LEDs) arranged in a horizontal line and displays the heating power of the left heating port 4L in multiple stages. The left heating power display unit 17L indicates the heating power by switching the lighting state (on, off, blinking, etc.) of the multiple LEDs or by switching the lighting color. This allows the user to be notified of the heating power in an intuitive and easy-to-understand manner.

[0107] The left operation section 15L is used to input operations related to cooking using the left heating port 4L. 7, the left operation unit 15L has five input keys 151L, 152L, 153L, 154L, and 155L. These input keys 151L, 152L, 153L, 154L, and 155L are capacitance-type touch sensor switches (touch switches) that can perform input by utilizing a change in capacitance when the user lightly touches them with a finger or the like, for example.

[0108] Light-emitting units 21L are provided corresponding to the input keys 151L, 152L, 153L, 154L, and 155L. The light-emitting units 21L are composed of a plurality of light-emitting elements (LEDs), and emit light in response to the operation of the input keys 151L, 152L, 153L, 154L, and 155L. Note that two adjacent input keys 154L and 155L share one light-emitting unit 21L because they perform the same function of increasing or decreasing the flame power.

[0109] The input key 151L is a key that is pressed when selecting timer cooking for the left heating port 4L. Timer cooking is a cooking method in which the user sets the cooking time and the heating operation is performed only for the set time.

[0110] The input key 152L is a key that is pressed when selecting a control menu to be implemented by the left heating port 4L. Each time the input key 152L is pressed, one of multiple control menus can be selected. The "control menu" referred to here is, for example, boiling water, stewing, frying (automatic cooking), etc. The operating time, heat power, operating pattern, etc. of the left heating port 4L differs for each control menu.

[0111] The control menu for using the left heating port 4L and the right heating port 4R by operating the left operation unit 15L or the right operation unit 15R without operating the central operation unit 15M is the control menu for the "single cooking mode" KM1, which uses induction heating only. The "single cooking mode" KM1 will be explained later.

[0112] The input key 153L is a key that is pressed to start or stop cooking using the left heating port 4L. That is, pressing the input key 153L drives the left IH coil 9L, which is located below the left heating port 4L. If the input key 153L is pressed again while the left IH coil 9L is being driven, the drive of the left IH coil 9L is stopped, and the induction heating operation is immediately stopped.

[0113] The input keys 154L and 155L are keys that are pressed to specify the heat level during heating cooking at the left heating port 4L. Pressing the input key 154L on the left decreases the heat level by one level. Conversely, pressing the input key 155L on the right increases the heat level by one level. The heat level during induction heating cooking at the left heating port 4L has nine levels, ranging from the minimum rated heat level (heat level 1: 150W) to the maximum rated heat level (heat level 9: 3200W).

[0114] 8 is an enlarged view of right display unit 16R, right heating power display unit 17R, and right operation unit 15R according to embodiment 1. Right display unit 16R displays information related to cooking using right heating port 4R and is implemented, for example, by a liquid crystal display. The information related to cooking using right heating port 4R displayed on right display unit 16R is the same as the information related to cooking using left heating port 4L.

[0115] The right heating power display unit 17R is composed of multiple light-emitting elements (LEDs) and displays the heating power of the right heating port 4R in multiple stages. Like the left heating power display unit 17L, the right heating power display unit 17R indicates the heating power by switching the lighting state (on, off, blinking, etc.) of the multiple light-emitting elements (LEDs) or by switching the lighting color.

[0116] The right operation unit 15R is used to input operations related to cooking using the right heating port 4R. As shown in Fig. 8, the right operation unit 15R includes five input keys 151R, 152R, 153R, 154R and 155R.

[0117] The input keys 151R, 152R, 153R, 154R and 155R are capacitance type touch switches that can perform input by utilizing a change in capacitance when the user lightly touches them with a finger or the like.

[0118] A light emitting unit 21R is provided corresponding to each of the input keys 151R, 152R, 153R, 154R, and 155R. The light emitting unit 21R is a light emitting element (LED), and the light emitting unit 21R corresponding to each of the input keys 151R, 152R, 153R, 154R, and 155R lights up in response to the operation of the input keys. However, two adjacent input keys 154R and 155R share one light emitting unit 21R because they perform the same function of increasing or decreasing the flame power.

[0119] The input key 151R is a key that is pressed when selecting timer cooking for the right heating port 4R. The input key 152R is a key that is pressed when selecting a control menu to be performed for the right heating port 4R.

[0120] Input key 153R is a key that is pressed to start or stop cooking using the right heating port 4R. Input keys 154R and 154R are keys that are pressed to specify the heat level during cooking using the right heating port 4R. Pressing left input key 154R decreases the heat level by one level. Conversely, pressing right input key 155R increases the heat level by one level. The heat level during induction cooking using the right heating port 4R has nine levels, ranging from the minimum rated heat level (heat level 1) of 150W to the maximum rated heat level (heat level 9) of 3200W.

[0121] FIG. 9 is an enlarged view of central display unit 16M, central operation unit 15M, and central heating status display unit 17M according to the first embodiment.

[0122] The central display unit 16M is configured as a liquid crystal display and displays information and warnings about the entire cooking appliance 1. The display screen of the central display unit 16M displays the selection result of the induction heating means (first heating means) HM1, the microwave heating means (second heating means) HM2, and the radiant heat heating means (third heating means) HM3, the operating status of each heating means, and caution or warning information regarding cooking using each heating means.

[0123] The central display unit 16M is a single LCD display in terms of hardware, but as shown in FIG. 9, it has three display areas: a first display area 22 on the left, a second display area 23 in the center, and a third display area 24 on the right, and each display area can display a different image. Depending on the display situation, the three display areas 22-24 may be linked together as a single (large) display area to display a single intended image. Hereinafter, the first display area 22 will be referred to as the first area 22, the second display area 23 as the second area 23, and the third display area 24 as the third area 24.

[0124] The central heating status display unit 17M is divided into two levels in the front-to-back direction, and the lower level (front side) is equipped with a microwave light-emitting element (LED) 310 located behind the microwave character display unit, a grill light-emitting element (LED) 311 located behind the grill character display unit, an oven light-emitting element (LED) 312 located behind the oven character display unit, and a central IH light-emitting element (LED) 313 located behind the central IH character display unit.

[0125] On the upper row (rear side) are warning letters saying "Caution: High temperature" and a group of high temperature warning light emitting diodes (LEDs) 314 arranged in front and below a diagram that schematically represents the heating chamber 6 and the three heating outlets 4L, 4C, and 4R.

[0126] The high temperature warning light emitting element (LED) group 314 is made up of a heating chamber high temperature warning light emitting element (LED) 314a and an IH high temperature warning light emitting element (LED) 314b arranged side by side.

[0127] The heating chamber high temperature warning light emitting element (LED) 314a lights up when the temperature inside the heating chamber 6 is high, for example, 50° C. or higher. The IH high temperature warning light emitting element (LED) 314b lights up when any of the left IH coil 9L, right IH coil 9R, and center IH coil 9C is in operation or when the temperature of the top plate 3 is high, for example, 50° C. or higher.

[0128] Central operation unit 15M is used to input operations mainly related to cooking in heating chamber 6 and cooking using central heating port 4C. As shown in FIG. 9, the central operation unit 15M includes nine input keys 151M, 152M, 153M, 154M, 155M, 156M, 157M, 158M, and 159M, and a function setting key 151KP (not shown).

[0129] The nine input keys 151M to 159M are capacitive touch switches. In addition, light emitting units 21M are provided near the input keys 151M to 159M, respectively.

[0130] The function setting key 151KP (not shown) is located on the leftmost side of the central operation unit 15M. This function setting key 151KP is used to set various operations, displays, etc. of the entire cooking appliance 1 as desired by the user.

[0131] When the function setting key 151KP (not shown) is pressed, the control device 40 (described later) switches to a "function mode" and displays the following "function setting menu" on the display screen of the central display unit 16M. (1) Child lock setting (setting to disable operation of various input keys). (2) Ventilation fan linkage mode setting. (3) Cleaning guide setting (setting the automatic notification function for when to clean the heating chamber 6 and exhaust vent cover 5). (4) Peak cut setting (maximum power consumption can be selected from one of four levels: 5700W, 5000W, 4800W, and 4000W). (5) Audio guide audio settings. (6) Audio guide volume setting. (7) Settings to prevent forgetting to remove food, cooking utensils, etc. from the heating chamber 6 (whether or not to issue an alarm on the audio notification unit 50 and central display unit 16M). (8) HEMS registration settings (settings related to the power usage restriction function of the home power control device). (9) Time unit setting for timer cooking (change from 1 minute to 5 or 30 minutes). (10) Switching between beginner mode and normal (expert) mode. (11) Setting the type (range) of inventory information SD1 to be acquired from an external device (refrigerator 800: not shown). (12) Setting the display priority (specific cooking menu to be displayed as default, identification information 167) of each cooking menu (for example, "hamburger steak") in the collaborative cooking mode KM3. (13) Setting the display priority (the specific control menu to be displayed by default) of each control menu of the combined cooking mode KM2 (for example, "Grill in the microwave" or "Pre-boil leafy vegetables"). (14) Setting of the cooking mode to be automatically displayed on the central display unit 16M when the door 7 of the heating chamber 6 is opened after the main power switch 20 is turned “ON” (such as the display priority between the linked cooking mode KM3 and the combined cooking mode KM2). (15) A setting for preventing the automatic display of additional information 165 and 166 (see FIG. 15) described later and a setting for preventing the audio notification unit 50 from notifying the additional information 165 and 166 by audio.

[0132] The "beginner mode" is an optional function for users who are unfamiliar with using the cooking appliance 1, and when the beginner mode is set, the voice guidance in the voice notification unit 50 becomes more detailed and thorough. Also, more voice guidance is provided for input operations in the input operation unit 15, and more information is displayed on the display screen of the central display unit 16M.

[0133] When the beginner mode is set, particularly in the case of cooking in the combined cooking mode KM2 and the linked cooking mode KM3, the amount of reference information (including, for example, additional information 165 and 166 described later) displayed on the display screen of the central display unit 16M increases in cooking step 1 and cooking step 2, or the content of the audio guidance in the audio notification unit 50 increases. This enhances the function of supporting the user's input operations.

[0134] In addition, in conjunction with switching from the "beginner mode" to the "normal (expert) mode", the content of the voice guidance from the voice notification unit 50 may be automatically set to not change.

[0135] When the door 7 of the heating chamber 6 is opened after the main power switch 20 (described later) is turned "ON," the cooking mode setting automatically displayed on the central display 16M refers to setting either the combined cooking mode KM3 or the combined cooking mode KM2. Because both the combined cooking mode KM3 and the combined cooking mode KM2 use the same central display 16M, the user can set the display of either mode to take priority. This will be explained in detail later. Note that in the first embodiment, the "combined cooking mode" KM2 here exceptionally includes the control menus of several single cooking modes, such as the single cooking mode KM1 using the central IH coil 9M.

[0136] When the door 7 of the heating chamber 6 is opened after the main power switch 20 is turned "ON", the control device 40 detects that the door 7 has been opened. There is a function that assumes that the user will be cooking using the heating chamber 6, and automatically displays either the first specific screen 16M1 for the linked cooking mode KM3 or the second specific screen 16M2 for the combined cooking mode KM2 on the central display unit 16M. The central display section 16M displays a standby initial screen 16MH (described later) immediately after the main power switch 20 is turned "ON." After that, the second specific screen 16M2 is automatically displayed immediately after the door 7 is opened.

[0137] After the "Function Setting Menu" is displayed on the display screen of the central display unit 16M, by "long pressing" (hereinafter referred to as "long pressing") one specific input key (e.g., 154M) other than the function setting key 151KP, one setting menu from the "Function Setting Menu" can be selected and subsequently changed to the desired setting content.

[0138] Alternatively, if two specific input keys other than the function setting key 151KP are simultaneously "pressed and held," one of the setting menus from the "function setting menu" described above can be called up and the desired setting can be changed.

[0139] The "long press" refers to a state where the button is pressed continuously for 5 seconds or more, for example. The control device 40 determines whether or not the state is a "long press" by comparing the timing of the touch input on the central operation unit 15M with a reference value. That is, the timing when the input keys (for example, 154M and 155M) on the central operation unit 15M are pressed simultaneously can be determined by the "ON" (when touched)-"OFF" (when not touched) signal sent from the input operation unit 15M to the control device 40, and the control device 40 measures the time from the "ON" signal to the time when it changes to the "OFF" signal to determine whether or not it is a "long press."

[0140] The type (range) of inventory information SD1 obtained from the refrigerator 800 (not shown) may be, for example, limited to only frozen foods, or limited to only ingredients that can be heated by a microwave heating source (second heating means HM2).

[0141] In the central display section 16M, when the control mode and control conditions (temperature, heat, time, etc.) of the first heating means HM1, the second heating means HM2 and the third heating means HM3 are being selected, the input function of the function setting key 151KP is disabled so as not to switch the function mode.

[0142] The following describes the setting of the peak cut value of the cooking appliance 1. Even if the default value at the time of shipping from the manufacturer is 5400W, it can be set to any of 5000W, 4800W, or 4000W when installed in the user's home.

[0143] In this way, the functions of the cooking appliance 1 can be changed using the function setting key 151KP to suit the user's wishes and the usage environment (power situation of the home where the appliance is installed), etc. When the peak cut value is set in this way, the setting result is stored in the control device 40, and is used to determine whether or not to permit use of the linked cooking mode KM3 when the user selects the linked cooking mode KM3, as will be described later. Therefore, the peak cut value cannot be changed using the function setting key 151KP (not shown) while cooking condition data, which will be described later, is being received from the communication terminal device 200.

[0144] The light emitting section 21M is composed of an LED, and emits light in response to the operation of the input keys 151M to 159M. The two adjacent input keys 155M and 154M have in common the function of changing the display content of the first area 22, and therefore share one light emitting section 21M.

[0145] The two adjacent input keys 157M and 156M have in common the function of changing the display content of the second area 23, and therefore share one light emitting section 21M. The two adjacent input keys 159M and 158M have in common the function of changing the display content of the third area 24, and therefore share one light emitting section 21M.

[0146] Input key 151M is a start key that is pressed (touch operated) to start cooking, and input key 152M is a cancel key that is pressed to stop or end cooking.

[0147] The input key 153M is a key that is operated to select the "single cooking mode" KM1, the "combined cooking mode" KM2, or the "cooperative cooking mode" KM3 that executes the "control menu" described above.

[0148] When any one of the "single cooking mode" KM1, "combined cooking mode" KM2, and "cooperative cooking mode" KM3 is selected, the selection result is displayed on the central display unit 16M. The "single cooking mode," "combined cooking mode," and "cooperative cooking mode" will be explained in detail later.

[0149] As shown in FIG. 9, the input keys 154M and 155M are located adjacent to and in front of the first area 22 of the central display unit 16M, and are keys for switching the display content of the screen displayed in the first area 22 of the central display unit 16M.

[0150] Next, FIG. 10 will be described. FIG. 10 is a plan view of the central display section 16M. When the input key 154M is pressed, that is, when the user operates it, the content displayed in the first area 22, for example, the display information 25A for "Microwave Manual" in one of the control menus belonging to the "Composite Cooking Mode" KM2, moves backward. At the same time, the display information 25B for "Pre-boil Leafy Vegetables" displayed in the front is moved to the center.

[0151] In addition, when the input key 155M is pressed, i.e., operated by the user, the display information 25A for "Microwave Manual" displayed in the first area 22 moves forward, and the display information 25C for "Warm" displayed at the rear is displayed in the center.

[0152] In this way, the user can select a specific control menu (for example, "manual range") within the "control menu" by operating the input keys 154M and 155M.

[0153] The control menu for the "manual range" originally belongs to the "single cooking mode" KM1, which uses only the second heating means HM2, but in addition to this, control menus (for combined cooking) belonging to the "combined cooking mode" KM2 and the "linked cooking mode" KM3, respectively, and control menus and linked cooking menus belonging to linked cooking menus (for example, "hamburger steak") are also displayed in the first area 22.

[0154] Then, when input key 151M is pressed, that is, when operated by the user, "Microwave Manual" is selected from the control menu displayed in the center in the case of FIG. 9. The corresponding heating starts, that is, the heating means (in this case, microwave oscillation source 11) is driven. Therefore, input keys 154M and 155M correspond to the selection keys of the control menu operated by the user. Similarly, they correspond to the selection keys of the control menu (for combined cooking). Furthermore, they also correspond to the selection keys of the linked cooking menu.

[0155] In Figure 9, input keys 156M and 157M are located adjacent to and in front of the second area 23 of the central display unit 16M, and are keys for switching the display content of the screen displayed in the second area 23 of the central display unit 16M.

[0156] 10, when input key 156M is pressed, the wattage (microwave output value) displayed in second area 23 ("500W" in FIG. 10) is increased by one step (to "600W", for example). Conversely, when input key 157M is pressed, the wattage displayed in second area 23 is decreased by one step (to "200W", for example).

[0157] By operating input keys 156M and 157M, the user can select the wattage (microwave output value) for microwave cooking performed in heating chamber 5 (a type of "single cooking mode" KM1 using microwave source 11).

[0158] The input keys 158M and 159M are arranged adjacent to the third area 24 of the central display unit 16M, in front of and near the third area 24, and are used to switch the display content displayed in the third area 24.

[0159] 10, when input key 158M is pressed, the heating operation time displayed in the third area 24 is increased by one step. Conversely, when input key 159M is pressed, the heating operation time displayed in the third area 24 is decreased by one step. The user can select the time for microwave cooking to be performed in heating chamber 6 by operating input keys 158M and 159M.

[0160] Next, FIG. 11 will be described. FIG. 11 is a control block diagram showing main functions of the cooking device 1 according to the first embodiment. As shown in FIG. 11, the cooking appliance 1 includes a control device 40 that controls the cooking appliance 1 as a whole.

[0161] The control device 40 is an electronic circuit board mounted with electronic components such as a control circuit that controls the operation of each component of the cooking appliance 1. The control device 40 controls the driving of the left IH coil 9L, the right IH coil 9R, and the center coil 9C (not shown) based on the operation of the left operating unit 15L and the right operating unit 15R and the temperature of the object to be heated on the top plate 3.

[0162] The control device 40 controls the operation of the central IH coil 9C, microwave heating means 11, upper radiant heat heating means 12a, and lower radiant heat heating means 12b based on the operation of the central operation unit 15M, the temperature of the heated object on the top plate 3, and the detection results of the infrared sensor 13 and the thermistor sensor 14.

[0163] Furthermore, the control device 40 controls the displays on the left display unit 16L, the right display unit 16R, the left heating power display unit 17L, and the right heating power display unit 17R based on the operations of the left operation unit 15L and the right operation unit 15R.

[0164] Furthermore, the control device 40 controls the display of the central display unit 16M and the central heating status display unit 17M based on the open signal from the open / close detection unit 10 and the operations of the left operation unit 15L, the right operation unit 15R and the central operation unit 15M.

[0165] The control device 40 has a storage device 41 that stores data such as various programs and parameters used to control the cooking appliance 1 (hereinafter collectively referred to as "control data") and data for the display screens displayed on the display units 16L, 16R, 16M, 17L, and 17R (hereinafter collectively referred to as "display condition data"). The control device 40 also activates the audio notification unit 50 as necessary to notify the user of the operating status of the cooking appliance 1 by audio.

[0166] The control device 40 stores in the cooking condition data storage section 42 of the storage device 41 various programs and data such as parameters (hereinafter referred to as "cooking condition data") used for the heating control of the heating control section 43 to control cooking.

[0167] The "cooking condition data" and the "display condition data" may be acquired by the cooker 1 from an external device such as the communication terminal device 200, either together or separately.

[0168] A storage unit 42 stores the "cooking condition data" and the "display condition data." The storage unit 42 may be configured as one section (area) in the storage device 41, or may be configured as a separate unit from the storage device 41 in terms of hardware.

[0169] Reference numeral 43 denotes a heating control section that performs integrated control of the overall heating operation of the cooking appliance 1, and is mainly composed of a microcomputer. Reference numeral 53 denotes a data acquisition unit that acquires the "cooking condition data" from the smartphone 200 or the cloud server 300 via the communication unit 51. In addition, the "display condition data" may also be acquired from the smartphone 200 or the cloud server 300 via the communication unit 51.

[0170] Reference numeral 51 denotes a communication unit that communicates wirelessly with the outside, and has a function of performing wireless communication 400 with the smartphone 200 as shown in Fig. 1 or 3. Alternatively, as shown in Fig. 2 and Fig. 3, it has a function of forming networks 203, 204, and 205 with the cloud server 300.

[0171] Reference numeral 54 denotes a permission condition determination unit that performs a process of determining whether cooking in the cooperative cooking mode KM3 is permitted. Reference numeral 57 denotes a power supply circuit, which supplies constant voltage power to the control device 40. Reference numeral 20 denotes a main power switch inserted into this power supply circuit 57.

[0172] A limiting unit 55 limits the acquisition of the cooking condition data 2. The restriction unit 55 has the function of restricting the data acquisition unit 53 from acquiring the cooking condition data 2 via the communication unit 51 during the waiting period before starting cooking in the collaborative cooking mode KM3 (i.e., before "cooking process 1" shown in Figure 29).

[0173] Furthermore, the restriction unit 55 has a function of restricting the acquisition of new cooking condition data from the communication unit 51 until the cooking process of the cooking menu to which the cooking condition data 2 acquired before the start of the cooking process 1 is applied is completed. The limiting unit 55 may be realized by a single control program of a computer (not shown) that constitutes the control device 40, and it is not necessarily required that the limiting unit 55 be configured separately on hardware from the control device 40.

[0174] (3. Control menu configuration of the central operation unit) Next, the selectable control menu displayed on the central display unit 16M by the central operation unit 15M will be described with reference to FIG.

[0175] FIG. 12 shows the entire control menu that can be selected using the central operation unit 15M. The control menus that can be selected by the central operating unit 15M are divided into an RG (range grill) menu group that uses the microwave heating means (second heating means HM2) and one or both of the upper radiant heat heating means 12a and the lower radiant heat heating means 12b, and an IH menu group that uses the central IH coil 9C corresponding to the central heating port 4C.

[0176] The control menu shown in Fig. 12 is categorized into four perspectives (categories 1 to 4) in Fig. 13. As is clear from Fig. 13, the control menu is roughly categorized into a single cooking mode KM1 and a combined cooking mode KM2. Although Fig. 12 and Fig. 13 do not show the combined cooking mode KM3, the central operation unit 15M can execute a combined cooking menu in the combined cooking mode.

[0177] When the main power switch 20 is turned "ON" and the input key 154M or 155R is pressed without operating the input key 153M of the central operation unit 15M, the combined cooking mode KM2 is selected.

[0178] Therefore, the display screen of the central display portion 16M is switched to the second specific screen 16M2. In the first area 22 of the second specific screen 16M2, the control menu "Warm" shown in the "Left Display Area" of Fig. 12 is always displayed first because this control menu "Warm" is set as the default.

[0179] The "left display area" in Fig. 12 is a display area that corresponds to the first area 22 described in Fig. 9. In other words, the various control menus shown in the "left display area" in Fig. 12 are displayed sequentially in the first area 22.

[0180] As shown in the "left display area" of Figure 12, in addition to "Warm," there are 13 control menus: "Microwave manual," "Pre-boil leafy vegetables," "Pre-boil root vegetables," "Defrost meat," "Microwave grill (RG) cooking," "Microwave grill (RG) reheat," "Microwave grill (RG) manual," "Grill," "Oven," "IH keep warm," "IH rice cooking," and "IH heating."

[0181] The control menus "Warm," "Microwave manual," "Pre-boil leafy vegetables," "Pre-boil root vegetables," "Defrost meat," "Microwave grill (RG) cooking," "Microwave grill (RG) reheat," "Microwave grill (RG) manual," "Grill," and "Oven" are included in the RG menu group. In addition, "IH Keep Warm," "IH Cooking," and "IH Heating" are included in the IH menu group.

[0182] The content shown in the "Central Display Area" in FIG. 12 is the content displayed in the second area 23 of the central display unit 16M, and relates to adjusting the heating conditions during cooking, such as temperature, time, heat, "high," or "low." In other words, the "Central Display Area" lists various control conditions. The default settings for this "Central Display Area" are listed in the "Default" column in the right column of the "Central Display Area."

[0183] The contents written in the "right display area" in Figure 12 indicate the contents displayed in the third area 24 of the central display unit 16M. The default settings for the "right display area" are listed in the "Default" column in the right column of the "right display area." A blank space does not indicate a control condition that can be changed, but rather indicates that no information is displayed, or that an appropriate explanatory text that cannot be selected or changed (by the user) is displayed in the third area 24.

[0184] Next, a total of 13 types of control menus displayed in the "left display area" of FIG. 12 will be described. (1) Warming: This refers to heating the food in the heating chamber 6 using the microwave heating means (second heating means HM2). This "warming" mode is also suitable for reheating food. The default setting is "80°C," so microwave heating will automatically stop once the food has heated to 80°C. Note that "80°C" is the target temperature, which can be adjusted by the user before heating begins. As shown in the central display area of ​​Figure 12, for example, the range from 0°C to 90°C can be set in 5-degree increments.

[0185] (2) Manual microwave operation: This refers to using the microwave heating means (second heating means HM2) to heat the food in the heating chamber 6. The heating time is set by the user to a specific time between 10 seconds and 60 minutes.

[0186] (3) Parboiling leafy vegetables: This method uses microwave heating means (second heating means HM2) to boil food in the heating chamber 6, particularly vegetables whose leaves are edible, such as spinach and Chinese cabbage. The infrared sensor 13 measures the temperature rise of the food in real time and automatically stops cooking.

[0187] (4) Pre-boiling of root vegetables: This method is suitable for boiling food items in the heating chamber 6, particularly roots, rhizomes, potatoes, and other root vegetables, using microwave heating means (second heating means HM2).

[0188] (5) Meat thawing: Suitable for thawing various frozen meats. (6) Range grill (RG) cooking: The food to be cooked in the heating chamber 6 is cooked by combining microwave heating using a microwave heating means (second heating means HM2) with oven heating using upper radiant heat heating means 12a and lower radiant heat heating means 12b.

[0189] (7) Range Grill (RG) Re-cooking: Suitable for re-heating food that has already been cooked in the heating chamber 6. (8) Range Grill (RG) Manual: The user can select between microwave heating and oven heating as appropriate to heat and cook the food in the heating chamber 6.

[0190] (9) Grill: This uses one or both of the upper radiant heat heating means 12a and the lower radiant heat heating means 12b to heat food in the heating chamber 5. In other words, this is a control menu that uses the third heating means HM3.

[0191] In the "grill" mode, the temperature of the heating chamber 6 is not managed, nor is a rise in the temperature of the food being cooked detected and the heating operation is stopped. The heating operation is performed for a time specified by the user, within a range of 10 seconds to 30 minutes.

[0192] (10) Oven: Either or both of the upper radiant heat heating means 12a and the lower radiant heat heating means 12b are used to heat the food in the heating chamber 6. The temperature of the heating chamber 6 is measured in real time by the thermistor sensor 14, and the power supply to the upper radiant heat heating means 12a and the lower radiant heat heating means 12b is controlled so that the temperature reaches the set target temperature.

[0193] (11) IH Warm: Heats an object to be heated, such as a pot, above the central heating port 4C so that it remains at the temperature set by the user. The induction heating power ranges from low to medium, ranging from 200W to 750W. A temperature sensor (not shown) installed near the central IH coil 9C detects the temperature of the object to be heated in real time, and the heating control unit 43 of the control device 40 controls the heating power based on the detected temperature. The default temperature is 80°C, as shown in FIG. 12. For example, this is suitable for keeping soup warm.

[0194] (12) IH rice cooking: Heats rice according to the number of servings (amount of rice cooked) set by the user. The induction heating power ranges from low to high, from 200W to 1500W. A temperature sensor (not shown) installed near the central IH coil 9C is used to detect abnormal heating of the heated object (also called overheating; the same applies below). If an abnormal temperature is detected, the control device 40 will reduce the heating power or stop the heating operation.

[0195] (13) IH heating: Heating is performed according to the induction heating power set by the user. There are five levels of heat power that can be set: Heat Power 1: 200W, Heat Power 2: 500W, Heat Power 3: 750W, Heat Power 4: 1000W, and Heat Power 5: 1500W. A temperature sensor (not shown) installed near the central IH coil 9C is used to detect abnormal heating of the heated object, and if an abnormal temperature is detected, the control device 40 reduces the heat power or stops the heating operation. The default heat power is 500W.

[0196] Next, FIG. 13 will be described. FIG. 13 is a classification table of the RG control menus ("RG menu group" in FIG. 12) and the IH control menus ("IH menu group" in FIG. 12) of the single cooking mode KM1 using the induction heating source 9.

[0197] The "left display area" of the first region in Fig. 13 means the first area. As is clear from Fig. 13, the names of the control menus shown in Fig. 13 are also displayed in text in the first area 22 of the central display unit 16M, and are used by the user to select from the control menu.

[0198] FIG. 14 is an explanatory diagram showing the storage structure of various cooking control menus for the cooperative cooking mode and the combined cooking mode, and the correspondence between the menus and input keys. Information indicating the main points of each control menu shown in category 2 of FIG. 13 is stored as data in the third layer of cooking condition storage unit 42 as shown in FIG.

[0199] Therefore, by operating input keys 154M and 155M to select a desired control menu, the user can automatically or arbitrarily display information indicating the main points of each control menu shown in category 2 in Fig. 13, which corresponds one-to-one to (is linked to) that control menu. Fig. 15 shows an example of this automatic display.

[0200] Next, the display on the central display unit 16M when the central operation unit 15M is operated will be described with reference to the schematic diagram of FIG. First, when the user presses the operation button 20A of the main power switch 20 (see Figure 11) to turn on the main power, the device enters a state in which it can accept operations from the left operation unit 15R, the central operation unit 15M, and the right operation unit 15R, and a predetermined screen (hereinafter referred to as the "standby initial screen" 16MH) is displayed on the central display unit 16M, although this is not shown.

[0201] In this state, when the user presses the input key 154M or 155M, the display screen 15ST is displayed on the central display section 16M as shown in FIG. As is clear from the display screen 15ST, the name 160 of the control menu "Warm" is displayed large in the center of the first area 22 in the front-to-back direction.

[0202] Behind the control menu identification information 160 for "warm" displayed in the center of the first area 22, the words "IH heating" (control menu identification information) 161 are displayed, and conversely, in front of it, the words "microwave manual" (control menu identification information) 162 are displayed in slightly smaller size.

[0203] This allows the user to see that when selecting a control menu, the next options are "IH heating" and "microwave manual." If, at this stage, the input key 154M is pressed once, the control menu identification information 162 for "microwave manual" is displayed large, as if it has moved (backward) to the position of the characters "warm" (control menu identification information) 160. Note that the characters of the control menu identification information 162 have not actually moved; the displayed information has simply switched.

[0204] Furthermore, when the input key 155M is pressed once, the characters "IH heating" (control menu identification information) 161 are displayed larger, as if they have moved (forward) to the position of the characters "warming" (control menu identification information) 160. Note that in this case too, the control menu identification information 162 has not actually moved, but the display information has simply been switched.

[0205] 15, the display screen 15ST displays a target temperature of "80°C" in the second area 23. When microwave heating is performed at this target temperature, microwave heating is automatically stopped when the infrared sensor 13 detects that the temperature of the food to be cooked is 80°C.

[0206] If you want to change the temperature displayed in this second area 23 and change the temperature at which the device automatically stops, simply operate input key 156M or 157M. Pressing input key 156M once will raise the temperature by 5°C to 85°C, as shown on display screen 15UP1, and pressing input key 167M once will lower the temperature by 5°C to 75°C, as shown on display screen 15DN1.

[0207] Also, in the second area 23, a heat source display section 163 is displayed which displays in text that the heat source is microwave heating means (second heating means HM2).

[0208] As described above, 164 is reference information that is automatically displayed to indicate that this is a recommended control menu for heating side dishes, etc. The content of this reference information may be other additional information 165, and two or more types of information may be displayed alternately or sequentially for several seconds each on the display screen (for example, third area 24) of central display unit 16M.

[0209] Furthermore, as shown in category 2 in FIG. 13, information (reference information) 164 indicating the main points of each control menu may be displayed at any time in response to the operation of the input key 158 or 159. In other words, in this embodiment 1, the reference information 164 that corresponds one-to-one with each control menu (e.g., "warming") is displayed so that the user does not have to wonder whether to select each control menu (e.g., "warming").

[0210] Furthermore, when reference information 164 is displayed as shown in FIG. 15, if one of the (two) input keys 158M or 159M located in front of the reference information 164 is touched, more detailed additional information 166 may be displayed in the third area 24 instead of the reference information 164.

[0211] As shown in Figure 15, the aforementioned "composite cooking mode" KM2 is a mode in which multiple heating means with different heating principles, such as the second heating means HM2 and the third heating means HM3, are driven simultaneously or automatically switched with a time lag to heat and cook a common food item.

[0212] In FIG. 15, the display screen of the central display section 16M is a display screen dedicated to the "combined cooking mode" KM2, and may be called a "second specific screen" 16M2.

[0213] Next, a description will be given of FIGS. 16 to 21. FIG. 16 is a plan view showing the relationship between the display operation of the central display unit 16M and the central operation unit 15M in the cooperative cooking mode KM3, showing a situation during a heating operation.

[0214] In FIG. 16, when the main power switch 20 is turned "ON" to start the control device 40 and the input key 153M of the central operation unit 15M is pressed, a first specific screen 16M1 shown in this FIG. 16 is displayed.

[0215] Even if the input key 155M or 156M is pressed first and the setting operation for a single cooking mode such as microwave heating or a combined cooking mode KM2 such as microwave grill (RG) cooking is halfway through, if the setting operation is at a stage before the input key 151M is pressed, the input process for the combined cooking mode KM3 will be changed when the input key 153M is pressed. In other words, from this stage, only the first specific screen 16M1 is displayed on the central display section 16M.

[0216] If input key 153M is touched, and then input key 154M or 155M is touched, further identification information (including a graphic mark and the name of the food item) 167 is displayed in the first area 22 of the display screen (first identification screen) 16M1 of the central display unit 16M to identify the food item that is the target of multiple collaborative cooking modes KM3 (the collaborative cooking menu).

[0217] In Figure 16, the number of "foods" that can be cooked in the cooperative cooking mode displayed in the central display section 16M is three: hamburger steak, gratin, and roast beef. In this way, the number of food items is called the "number of cooperative cooking menus."

[0218] In this first embodiment, there are a total of eight cooperative cooking menus. Details will be explained in Figures 17 and 18. However, it is possible to acquire cooking condition data from a smartphone (communication terminal device) 200 (described later) to further increase the number of cooperative cooking menus.

[0219] 16, 167, 168, and 169 are identification information, which in this first embodiment is information that indicates the names of the foods to be cooked (e.g., hamburger steak, gratin, roast beef) one-to-one. Note that when describing all the identification information for the coordinated cooking menu, the reference number 167 is used.

[0220] The position where the control menu identification information 160 (see FIG. 15) is displayed may be hereinafter referred to as "display position A." In contrast, in the cooperative cooking mode KM3, the position where the identification information 167 is displayed may be hereinafter referred to as "display position B."

[0221] In this embodiment 1, "display position B" and the "display position A" (see FIG. 15) are set to the same position, but they may be set to different positions. However, to avoid user confusion, the eight cooperative cooking menus in the cooperative cooking mode KM3 are always set to the same position (display position B). Also, in the combined cooking mode KM2, it is preferable to always unify the eight control menus to the same (single) "display position A."

[0222] In Figure 16, the operation support information 170 displays "Press the start button to start heating with the left IH." This means that by pressing the input key 151M on the central operation unit 15M, induction heating (in the combined cooking mode KM3) can be started with the left IH coil 9L. However, in this first embodiment, it is necessary to press the input key 153L on the left operation unit 15L after pressing the input key 151M.

[0223] As shown in FIG. 16, above (behind in plan view) the identification information 167 shown on the first specific screen 16M1, identification information 168 indicating the name of another food item (for example, gratin) is displayed.

[0224] Furthermore, identification information 169 indicating the name of another food item (for example, roast beef) is displayed below the identification information 167. In Fig. 16, one light emitting unit 21M corresponding to an input key 151M is surrounded by a dashed circle, which indicates that the light emitting unit 21M is blinking (or emitting light in a color different from the other light emitting units) and waiting for a command to start cooking.

[0225] Next, FIG. 17 will be described. In the same way as switching the display between the combined cooking mode KM2 and the single cooking mode KM1, by operating the two input keys 154M and 155M, it is possible to select the food to be cooked in the combined cooking mode KM3.

[0226] That is, each time either input key 154M or 155M is operated once, the identification information 167 indicating the name of the food to be cooked (for example, hamburger steak) changes its display by moving sequentially upward or downward by one step. That is, by forward and backward movement, the identification information 167 can be sequentially displayed at a predetermined position (front-rear center position) in first area 22L, in other words, at display position B.

[0227] In this first embodiment, as mentioned above, there are a total of eight types of food to be cooked in the cooperative cooking mode KM3. Therefore, for example, if the left input key 155M is operated eight times, the identification information 167 of one food to be cooked (e.g., hamburger steak) will cycle through. Conversely, if the right input key 154M is operated eight times, the identification information 167 of one food to be cooked (e.g., hamburger steak) will cycle through.

[0228] In Fig. 17(A), FG indicate the user's fingertips. Every time input key 155M is pressed once, the display contents of first specific screen 16M1 change to display screens 17A to 17D as shown in Fig. 17(B).

[0229] Referring to FIG. FIG. 18 is a table showing the correspondence between the cooking menu in the cooperative cooking mode KM3 and the operation support information 170.

[0230] As can be seen from Fig. 18, there are two types of operation support information 170: operation support information A and operation support information B. One is information that says "Press the start button to start heating the left IH cooker," and the other is information that says "Press the start button to confirm." This "start button" refers to input key 151M.

[0231] The two types of operation support information 170 are automatically switched before the start of the cooking process in the cooperative cooking mode KM3, and are displayed alternately, for example, every few seconds.

[0232] Next, FIG. 19 will be described. In this first embodiment, a "cooperative preheat cooking mode" KM4 is provided as one type of the cooperative cooking mode KM3. There are two types of linked preheat cooking mode KM4.

[0233] An example of a cooking menu that utilizes the linked preheat cooking mode KM4 is "hamburger steak." In the case of this "hamburger steak," the preheating process is performed by the induction heating source 9 (first heating means HM1).

[0234] If the cooking process 1 is started while the preheating process is being performed (by the induction heating source 9), the heating operation of the preheating process has not been stopped at the time when the cooking process 1 is started. Therefore, the energization of the induction heating source 9 and the energization of the second heating means HM2 (microwave heating means) and the third heating means HM3 in charge of cooking process 1 are carried out in parallel in the same time period.

[0235] In other words, in the linked preheating cooking mode KM4, the heating source (in the above description, the first heating means HM1) that has started operating before the cooking process 1 is not necessarily stopped at the start of the cooking process 1, and during the cooking process 1, power may be supplied to either or both of the second heating means HM2 (microwave heating means) and the third heating means HM3.

[0236] Unless otherwise specified, the following description will be given on the assumption that the cooperative cooking mode KM3 includes the cooperative preheat cooking mode KM4.

[0237] When the cooperative cooking mode KM3 is selected, once the identification information 167 indicating the name of the food to be cooked is displayed on the central display unit 16M, the left operating unit 15L of the left IH coil 9L cannot be used for other cooking menus.

[0238] Specifically, among the various input keys on the left operation unit 15L, at least the input key 153L is disabled by the heating control unit 43. This "disabled" means that the input key 153L does not transmit a valid command signal to the heating control unit 43, and that even if a valid command signal is transmitted, the heating control unit 43 does not process the command signal as a valid command signal. In either case, heating with the left IH coil 9L cannot be selected.

[0239] At the same time, when the identification information 167 is displayed, the right operation unit 15R of the right heating port 4R may be made unavailable (by "disabling" the input key 153R). However, if the user has previously set the function on the input operation unit 15 (using the function setting key 151KP) to prevent this "disabling," and if the right IH coil 9R is already being used for another control menu (heating operation is ongoing), the right IH coil 9R can be used as is. On the other hand, in the cooperative cooking mode KM3, the fact that it has been used previously determines that it cannot be used (by the heating control unit 43).

[0240] Therefore, only the left IH coil 9L is "occupied" by selecting the combined cooking mode KM3. Also, from the perspective of the first heating source HM1 as a whole, only a portion of the three heating elements (the left IH coil 9L) is "restricted" from use. Note that if the right IH coil 9R is not being used for other cooking, the right IH coil 9R may also be placed in an occupied state.

[0241] Continuing with the explanation of FIG. 19 shows the operation steps when "fried chicken" is made in the cooperative cooking mode KM3. In FIG. 19, #1 to #9 indicate user operations and state changes of the cooker 1.

[0242] 19 differs from the case of the above-mentioned "hamburger steak" in that cooking step 1 is performed in heating chamber 6 and cooking step 2 is performed by induction heating source 9.

[0243] In Figure 19, before starting cooking step 1 to cook "fried chicken," the user first selects the left IH coil 9L and presses the input key 151L. Then, preheating of the object to be heated placed on the top plate 3 begins. In this case, the object to be heated is a metal pot or frying pan, etc., with a certain amount of cooking oil added.

[0244] Meanwhile, the user opens the door 7 of the heating chamber 6 and places ingredients for "fried chicken" (such as seasoned chicken) into the heating chamber 6 (#1). Then, after closing the door 7, an operation A23 called "pressing the start button" is performed. This operation is performed by pressing the input key 151M of the central operation unit 15M.

[0245] At this point, the microwave heating source (second heating means HM2) is activated to start microwave cooking step 1. Then, notification 1 of reference information is performed.

[0246] The notification 1 may be, for example, "Microwave heating has started. Heating time is xx minutes." This may be information indicating the time until the end of heating. Alternatively, if the control is such that the end time of heating is determined by detecting the temperature of the food to be cooked, this may be information indicating the target temperature, such as "Heating to xx°C."

[0247] During this cooking step 1, the preheating of the left IH coil 9L is completed (for example, the object to be heated is heated to 180°C, which is the standard preheating temperature). The user is notified of this preheating completion by voice and text, etc., via the audio notification unit 51 and the central display unit 16M (first specific screen 16M1) (#2).

[0248] The user can stop microwave heating at any time during cooking process 1. To stop the microwave heating, simply open door 7. Microwave heating can be stopped by pressing input key 152M on central operation unit 15M only once. However, pressing input key 152M twice in a short period of time will cancel the cooking mode, and the selection of "fried chicken" in the linked cooking mode will be canceled.

[0249] By opening the door 7, the microwave heating operation is immediately stopped, and cooking step 1 ends (#3). Next, the user moves the food material that has been heated in the heating chamber 6 into the object to be heated that has been preheated on the top plate 3 (#4).

[0250] Then, cooking process 2 begins with left heating port 4L (#5). In cooking step 2, input key 153L (see FIG. 7) on left operation unit 15L is pressed first before preheating begins, so there is no need to operate left operation unit 15L at the start of cooking step 2. In other words, when ingredients (fried chicken ingredients) are moved into an object to be heated that has been preheated to, for example, 180°C, heating of the ingredients begins at the temperature of the object to be heated (this point marks the start of cooking step 2).

[0251] As described above, the user does not need to operate the input operation unit 15 in order to start cooking step 2 (#5). The start of cooking process 2 occurs when the food to be cooked is placed on top of the food to be heated and is ready to be heated. However, the temperature sensor group 30 (see Figure 11) may detect a temporary drop in the temperature of the food to be heated when the food is placed on top, and the start of cooking process 2 may be determined electrically. Cooking step 2 can be ended at any time by the user operating left operating unit 15L.

[0252] The user then moves the food again. First, the door 7 is opened, the food to be cooked is placed in the heating chamber 6, and the door 7 is closed (#6). Then, the input key 151M on the central operation unit 15M is pressed to start cooking step 3 of the range grill control menu (RG control menu).

[0253] When a predetermined time (TN5) has elapsed since the cooking process 3 by the range grill driving unit in the heating chamber 6 was started by the user's operation input A26, a notification 2 of the reference information 5 is made.

[0254] The reference information notification 2 is information including guidance such as, for example, "Heating will finish in 30 seconds. If you wish to extend the time further, please set the time." Furthermore, since the user knows that the final cooking process is about to end, the user can start preparing to remove the "fried chicken" from the heating chamber 6 from the point of time when the reference information notification 2 is displayed. In synchronization with this, the central display unit 16M displays the content of the notification 2 in text or the like. The notification 2 is displayed at a specific position on the first specific screen 16M1, just like the operation support information 170.

[0255] Thereafter, the microwave heating operation is stopped, and cooking step 3 is completed (#7). Note that cooking step 3 can be stopped immediately if the user opens door 7. Then, the user moves the food heated in the heating chamber 6 into the food to be heated that is being preheated on the top plate 3 (#8). In this case, if the food to be heated is maintained in a heated state by induction heating until the end of cooking step 3, further induction heating (cooking step 4) may be performed (#9).

[0256] Induction heating cooking can be ended by operating the left operation unit 15L. That is, the user's operation A28 is to press the input key 153L of the left operation unit 15L corresponding to the left IH coil 9L.

[0257] The cooking sequence shown in FIG. 19 can shorten the time required from the start of the induction heating operation (start of the preheating step) to the end of cooking step 1. That is, the food material (food to be cooked) is placed in heating chamber 6 and cooking step 1 is started before the completion of preheating by induction heating or notification of the completion of preheating.

[0258] Since preheating by the induction heating source (first heating means HM1) is completed before cooking process 1 is completed, the food to be cooked can be immediately transferred into the food to be heated on top plate 3 after cooking process 1 is completed, and cooking process 2 can be started.

[0259] In the example of "fried chicken" in Figure 19, cooking step 3 was included, but cooking step 3 and cooking step 4 are not necessarily required. Cooking steps can be completed as needed depending on the type of food to be cooked and the user's wishes.

[0260] 19 shows that the "left IH coil drive period" continues even after cooking step 2 is completed, but the drive of the left IH coil 9L can be stopped at any time using the left operation unit 15L after cooking step 2 is completed. However, as shown by the dashed line in FIG. 19, if the left IH coil 9L is to be used in cooking step 4 as well, it is necessary to start the preheating operation again before cooking step 4.

[0261] Next, FIG. 20 will be described. Like FIG. 19, FIG. 20 shows the operation steps when "fried chicken" is selected as the cooking menu in the cooperative cooking mode KM3. 20, #1 to #9 indicate user operations and state changes of the cooking appliance 1, as explained in FIG. 19. The other symbols correspond to those in FIG.

[0262] The difference between FIG. 20 and FIG. 19 will be explained. FIG. 20 shows a case where cooking step 1 is started in heating chamber 6 after the induction heating source (first heating means HM1) has completed preheating of the object to be heated and a notification of this (#2) has been received.

[0263] When the completion of preheating of the object to be heated by the induction heating source is displayed on the first specific screen 16M1 and the left and right display units 16L and 16R, and is also notified by audio notification unit 50, the user opens door 7 of heating chamber 6 and places the ingredients for "fried chicken" (such as seasoned chicken) into heating chamber 6 (#1). Then, after closing the door 7, the input key 151M of the central operation unit 15M is pressed.

[0264] At this point, microwave cooking step 1 begins. Then, the reference information notification 1 is performed. After this, the process is the same as that shown in FIG.

[0265] In the cooking sequence shown in FIG. 20, the time required from the start of the heating operation (start of the preheating step) of the induction heating source (first heating means HM1) to the end of cooking step 1 is longer than that in FIG.

[0266] However, since heating of the ingredients (food to be cooked) in the heating chamber 6 begins after the preheating by the first heating means HM1 is completed or a notification of the completion of preheating is received, once cooking step 1 in the heating chamber 6 is completed, there is a guarantee that cooking step 2 can be immediately started by the induction heating source 9 if the food to be cooked is moved. Therefore, this method is suitable for users who are not very familiar with the linked preheating cooking mode KM4.

[0267] 20 shows that the "driving period of the left IH coil 9L" continues even after cooking step 2 is completed, but if the induction heating source (first heating means HM1) is not used after cooking step 2 is completed, the driving of the left IH coil 9L may be stopped at any time by the left operating unit 15L after cooking step 2 is completed. However, as shown by the dashed line in FIG. 20, if the left IH coil 9L is also used in cooking step 4, preheating must be started again before cooking step 4.

[0268] 19 and 20, the induction heating source (first heating means HM1) is energized first to start the preheating operation, while the cooking process 1 is carried out in the heating chamber 6. In the configuration shown in FIG. The "linked preheat cooking mode" KM4 of this first embodiment is not limited to the case where cooking step 1 is performed in the heating chamber.

[0269] In another linked preheating cooking mode KM4, a heating operation is first started by the first heating means HM1, an object to be heated such as a frying pan is heated to a preheat target temperature (for example, 180°C), and when the target temperature is reached, an object to be cooked is placed on the object to be heated, thus starting cooking step 1. After this preheating step, the object to be cooked may be moved into heating chamber 6 while still on top of the object to be heated, and cooking step 2 may be performed in order to further heat the object together with the object in heating chamber 6 using second heating means HM2 or third heating means HM3.

[0270] Next, a description will be given of Fig. 21. Fig. 21 is a flowchart showing the control operation of the heating control unit 43 until the transition to the combined cooking mode KM3.

[0271] In the combined cooking mode KM3 of this first embodiment, there is a pattern (first combined cooking mode) in which the induction heating source (first heating means HM1) is driven first, and then at least one of the second heating means HM2 and the third heating means HM3 is driven. Typical examples of cooking menus suitable for cooking in this pattern are four, such as hamburger steak and gratin, as shown in the table in Figure 18.

[0272] There is also a second cooperative cooking mode in which the order is reversed. Typical examples of cooking menus suitable for this second cooperative cooking mode are the four listed in the bottom half of the table in Figure 18, such as fried chicken and tempura.

[0273] The steps in FIG. 21 are common to both the first collaborative cooking mode and the second collaborative cooking mode. First, in the first step S1, the input key 153M of the central operation unit 15M is operated, which starts the cooperative cooking mode KM3.

[0274] In the next step S2, the first specific screen 16M1 is displayed on the central display unit 16M, and various information for executing the cooperative cooking mode KM3 is displayed. In this step S2, in order to select a cooking menu for each cooperative cooking mode, the "name of the food to be cooked" (e.g., "hamburger steak") 167 is displayed as a type of identification information in the center of the front-rear direction of the first area 22, i.e., at the display position B.

[0275] Depending on the selection of the cooperative cooking mode KM3, the timing at which the heating means (the first heating means HM1 to the third heating means HM3) are "occupied" may be either of the following two cases. (1) As described above, for example, after the case where the left IH coil 9L for cooking process 1 is selected (in FIG. 21, this corresponds to "occupied state start (case 2)" after step S4). (2) As shown in Figure 21, from step S2 onwards (in Figure 21, this corresponds to "Start of Occupancy State (Case 1)").

[0276] In the next step S3, it is determined whether at least one of input keys 154M and 155M has been operated. As described in Figures 9, 16, and 17, by operating two input keys 154M and 155M, it is possible to select identification information 167 indicating the name of an item to be cooked in the collaborative cooking mode (for example, hamburger steak).

[0277] If the input keys 154M and 155M are not operated (within a certain period of time), the process proceeds to step S4. In step S4, as described above, the user selects one of the two heating unit specification sections 171L and 171R displayed on the first specification screen 16M1. By operating the input keys 157M and 156M adjacent to each other on the left and right, the user can select either the right IH coil 9R or the left IH coil 9L.

[0278] Note that the left heating outlet 4L may be set as the default, the heating unit specification section 171L may be displayed first on the first specification screen 16M1, and the process may proceed directly to step S5. In the example described in Fig. 16, when hamburger steak is cooked using coordinated cooking, the left heating outlet 4L is set as the default, and the left IH coil 9L is set to be selected preferentially.

[0279] In the next step S5, it is determined whether an input operation has been performed to cancel the selection of the cooperative cooking mode. If the input key 152M has been operated once, the determination is "Yes." The process then returns to step S3. If the input key 152M has been operated twice consecutively within a certain short period of time (for example, five seconds), it is determined that the cooperative cooking mode KM3 has been canceled, and the process returns to the state of the standby initial screen before step S1. Therefore, the selection of the three cooking modes KM1 to KM3 returns to the initial stage.

[0280] On the other hand, if the input key 151M is operated while the input key 152M is not operated, the process proceeds to the next step S6, where cooking step 1 of the cooperative cooking mode KM3 is started.

[0281] 21, in step S7, in the operation program for the cooperative cooking mode KM3, various functional parts are activated according to the "cooking condition data" (including control condition data) of a specific cooperative cooking menu (recipe) such as "hamburger steak." In other words, the cooperative cooking mode KM3 is entered from this stage.

[0282] First, in step S7, the display unit corresponding to the heating unit selected in step 4 is activated. However, in the case of a cooking menu (for example, "fried chicken" as described above) that uses microwave heating means (second heating means HM2) or third heating means HM3 in cooking step 1, central display unit 16M is already activated, so no new display unit is activated in step S7.

[0283] In the case of a cooking menu that uses the left IH coil 9L in cooking step 1, for example, the left display unit 16L is activated in step S7. The input function of the left operation unit 15L is then enabled, and the system waits for user input. Then, the process proceeds to step S8.

[0284] In step S8, the operation of the input key 153L is awaited, and the cooking process of the cooperative cooking mode KM3 is started. The display content of the first specific screen 16M1 in step S8 includes process information 172, such as the fact that the left IH coil 9L is used in the first cooking process 1, and that a microwave heating means (second heating means HM2) is used in the next cooking process 2, as described in FIG. 16.

[0285] Next, Fig. 22 and Fig. 23 will be described. Fig. 22 is a flowchart showing the control operation of heating control unit 43 until the transition to the cooperative cooking mode. Fig. 23 is an explanatory diagram showing the permission conditions and the determination results before the transition to the cooperative cooking mode.

[0286] 22. Steps ST1 to ST8 are operation steps defined in the operation program (including cooking condition data) of the heating control unit 43 for the combined cooking mode KM3. First, when the operation button 20A of the main power switch 20 is pressed (ST1), the next step ST2 is a step in which the heating control unit 43 determines whether or not there is an abnormality.

[0287] At step ST2, central display unit 16M is activated and displays a message that "There is no abnormality, so cooking can begin." At this stage, heating control unit 43 also checks whether it has received a setting command from input operation unit 15 regarding the upper limit of total power consumption.

[0288] If the setting is made in step ST2 such that start-up information is transmitted from the cooking appliance 1 to the communication terminal device 200 or the cloud server 300, the start-up information is transmitted at this stage.

[0289] In the next step ST3, the central display unit 16M and the audio notification unit 51 also provide notification and audio guidance to prompt the user to select the heating means. In the next step ST4, the central display section 16M displays the initial standby screen, and also displays usage precautions for the user.

[0290] Then, it is determined whether an input key other than the input key 153M (for example, 154M) has been operated (ST5). If the input key 153M has been operated, step STC becomes "No" and the process proceeds to step ST6. That is, the process proceeds to the step of using the cooperative cooking mode KM3.

[0291] In step ST6, the permission condition determination unit 54 checks whether the "permission conditions" are met. For example, it checks the usage status of the heat source used in the combined cooking mode KM3. The permission conditions and the judgment results will be explained in detail in the next Figure 23.

[0292] In step ST5, the first input operation is checked. For example, it is determined whether the left operation unit 15L or the right operation unit 15R was operated before pressing the input key 153M, and it is also determined whether the composite cooking mode KM2 was selected by the central operation unit 15M (by the input key 154M or 155M).

[0293] If the input key 153M is operated for the first time within a certain grace period (for example, 30 seconds) from step ST3, the display for the cooperative cooking mode KM3 starts as described above.

[0294] On the other hand, if the input key 153M is not operated and another input key (for example, the input key 155M or 154M) is touched, the determination in step ST5 is "Yes," and the process proceeds to step ST9 to start cooking in a mode other than the cooperative cooking mode KM3. A detailed description of step ST9 will be omitted here.

[0295] In FIG. 22, steps ST6 and ST7 are operation steps for "permission condition 1" that determine whether cooking in the collaborative cooking mode KM3 is permitted. Step ST6 is a stage for determining "permission condition 1."

[0296] Here, "Permission Condition 1" means: (1) The "peak cut value" that specifies the upper limit of the maximum power that can be used by the heating cooker 1 is 5000W or more. (2) When a power reduction command signal is received by the control device 40 via the communication unit 51 from the external cloud server 300 or the communication terminal device 200, the peak cut value of the reduction command is 5000 W or more; If these two conditions are met, the result of step ST6 is "Yes."

[0297] The "permission condition 2" in the next step ST7 is the following three. (1) In the first heating means HM1, the central heating port 4C is not in heating operation. (2) Either the second heating means HM2 or the third heating means HM3, or both of them, are not in heating operation.

[0298] (3) In the first heating means HM1, neither the right heating port 4R nor the left heating port 4L is being used for heating (or only one of them is being used for heating). In other words, neither the left IH coil 9L nor the right IH coil 9R is being used for heating.

[0299] If the above three conditions are met, the determination in step ST7 is "Yes," and the process proceeds to step ST10. That is, the process can proceed to the step of inputting a command to start cooking in the cooperative cooking mode KM3.

[0300] If the determinations in steps ST6 and ST7 are "No," the process proceeds to step ST8, and the central display unit 16M and the audio notification unit 50 notify the user that the combined cooking mode KM3 cannot be selected.

[0301] Here, we will explain the meaning of the provision that "5000 W or more" in the "permission condition 1" above. For simplicity, the following explanation will not specifically mention the power consumption of electrical components other than the heat source, such as the internal cooling fan (not shown) of the main body 2.

[0302] The reason why the required demand (pre-securing of power demand) when implementing the collaborative cooking mode KM3 is 5000W or more is because the maximum (instantaneous) power consumed by each heating source during operation in the collaborative cooking mode is as follows:

[0303] (1) Microwave operation (second heating means HM2): 1000W (2) Oven operation: 2000 W (upper radiant heat heating means 12a: 1000 W, lower radiant heat heating means 12b: 1000 W) (3) Range grill operation: 1500W (second heating means HM2: 500W, upper radiant heat heating means 12a: 1000W)

[0304] On the other hand, the maximum power consumption for the cooking menu in the collaborative cooking mode KM3 is 1500W. Therefore, in the combined cooking mode, the second heating means HM2 and the third heating means HM3 may operate simultaneously.

[0305] In other words, the maximum power is 3500W, which is the sum of the 1000W of the second heating means HM2, the 1000W of the third heating means HM3 (2000W is achieved by alternating current of 1000W each), and the 1500W of the first heating means HM1 which performs induction heating.

[0306] If the demand (pre-securing power demand) is 5000W: When the right IH coil 9R is heating at 3000W (normal heating), the remaining demand is 2000W. If you start the linked cooking mode KM3 from this state, the remaining demand is 1500W short of the 3500W of power required for linked cooking, so you can reduce the heat output of the right IH coil 9R to 1500W (from 3000W) and start linked cooking.

[0307] If the demand (pre-determined power demand) is 4000W: When frying food using right heating outlet 4R (requiring a maximum of 1500W), the remaining demand will be 2500W. If coordinated cooking is performed from this state, the remaining demand is 1000W short of the 3500W of power required for coordinated cooking, so the heat power of the right IH coil must be reduced. However, if the heat power is reduced while the automatic control menu is running, cooking will not go well, so the heat power for the automatic control menu cannot be reduced. In the end, 4000W is not enough to provide the necessary heat output for the automatic control menu.

[0308] As is clear from the above explanation, before starting the collaborative cooking mode KM3, it is necessary to determine (confirm) whether there is a demand (pre-reservation of power demand) of 5000W, which is the sum of the power required for collaborative cooking (3500W) and the power required for the cooking menu of the right heating port 4R or the left heating port 4L (1500W).

[0309] Next, FIG. 23 will be described. Fig. 23 shows the determination processing of steps ST6 and ST7 in Fig. 22. These determinations are made by the permission condition determination unit 54. Step ST5 is the stage where the input key 153M is operated. In the next step STX1, the permission condition determination unit 54 of the control device 40 compares the latest state of the cooking device 1 with the permission conditions 1 and 2 described above, and determines whether the state satisfies permission conditions 1 and 2.

[0310] 23, voice (notification) 1 to voice (notification) 4 indicate the contents notified to the user by the voice notification unit 50. That is, this is a specific example of the contents of step ST8 in FIG.

[0311] Display 1 to Display 4 in Fig. 23 show the contents displayed on the central display unit 16M. Note that Display 1 to Display 4 are not displayed on the first specific screen 16M1 that is displayed from step S2 in Fig. 21 onwards, but are displayed on the central display unit 16M where the first specific screen is not displayed.

[0312] The first specific screen 16M1 is not displayed unless the prerequisites for transitioning to the collaborative cooking mode KM3 (permission conditions 1 and 2) are met. Therefore, after the user sets (selects) various conditions for the "collaborative cooking mode" KM3 (for example, the identification information 167), it is not determined that permission condition 1 or permission condition 2 is not met, and the display does not return to the initial standby screen (step ST4 in FIG. 22). Therefore, the user is not forced to perform unnecessary input operations.

[0313] FIG. 24 illustrates the operation from when the cooking appliance 1 is started up until when recipe information (cooking condition data) for cooking for the cooking appliance 1 is acquired from the communication terminal device 200 or the cloud server 300.

[0314] In this embodiment 1, the cooking condition data for the collaborative cooking mode KM3 includes, but is not limited to, the number (identification information) of the collaborative cooking menu, the order of the multiple heating means to be used, the heating means to be used in cooking step 1, the heating means to be used in cooking step 2, if there are cooking steps 3 and beyond, the heating means to be used for each of those cooking steps, and if there are default (standard setting) control conditions (heat power, heating time, target heating temperature, etc.) for each cooking step, the setting value or range of setting values.

[0315] In FIG. 24, steps SS1 to SS8 are operation steps defined in the integrated control program of the control device 40, and basically match the content defined in the operation program of the cooperative cooking mode KM3 described in FIG.

[0316] First, when the operation button 20A of the main power switch 20 is pressed (SS1), the next step SS2 is a step in which the heating control unit 43 determines whether or not there is an abnormality.

[0317] Steps SS1 to SS4 are the same as steps ST1 to ST4 described with reference to FIG. 22, so a duplicated description will be omitted.

[0318] In step SS5, the cooking appliance 1 displays a confirmation screen on the central display unit 16M and also notifies the user via the audio notification unit 50 to ask whether or not to send a signal to the communication terminal device 200 or cloud server 300 that has been registered in advance to request the provision of cooking recipe information (cooking condition data).

[0319] This external connection in step SS5 is automatically performed at a specified timing if the user sets it in advance using the input operation unit 15. In other words, the next step SS6, in which communication with an external device (the communication terminal device 200 or the cloud server 300) is automatically performed after step SS4, is omitted.

[0320] If the external connection is not set to be performed automatically, in step SS6, a predetermined icon or the like is displayed on the central display unit 16M to ask the user to confirm whether or not it is OK to request the provision of recipe information (cooking condition data).

[0321] If the user does not agree to the connection to the external device in step SS6, a non-reception message such as "receipt of recipe information (cooking condition data) is not currently being received" is sent to the registered external device (the communication terminal 200 or the cloud server 300) as shown in step SS9. In this way, the user can also set to refuse reception.

[0322] On the other hand, if the connection to the external device is agreed upon in step SS6, the data acquisition unit 53 of the cooking appliance 1 acquires recipe information (cooking condition data) from the external device via the communication unit 51. The acquired recipe information is stored in a predetermined "temporary storage unit" (not shown) in the cooking condition data storage unit 42.

[0323] In the next step SS7, the contents of the recipe information acquired from the external device, particularly the identification information 167, are displayed on the central display unit 16M. Also, the audio notification unit 50 notifies the fact of reception, for example, by saying, "A hamburger recipe has been received."

[0324] The period indicated by the thick arrow in FIG. 24 is the initial period TA, during which the limiting unit 55 can acquire cooking condition data under certain conditions, such as satisfying the "permission condition 1."

[0325] Next, FIG. 25 will be described. FIG. 25 shows the display contents of the central display section 16M corresponding to each operation step explained in FIG.

[0326] Referring to Figure 25, when the main power switch 20 is turned off, the central display unit 16M is not activated and therefore does not display any information. When the main power switch 20 is turned on, the control device 40 performs a self-diagnosis of whether or not there is an abnormality as described above, and then displays the display screen 1 of FIG. 25 on the central display unit 16M.

[0327] In the display screen 1 in Fig. 25, 60A is a display message informing that the power is on. 60B is two-dimensional information (two-dimensional code) for guiding to the recipe information providing server 301, which is a dedicated recipe posting site, via the network (Internet) 203, 204. 60C is text explaining the meaning of the two-dimensional code (hereinafter referred to as "two-dimensional information explanation text").

[0328] When the two-dimensional code 60B is optically read by the communication terminal 200, it can be connected to the recipe information providing server 301 that stores information on various cooking recipes. This two-dimensional information explanation 60C and the display text 60A are a type of "common information during standby" 60N.

[0329] After the display screen 1 in FIG. 25 is displayed, the display screen 2A or 2B may be displayed automatically. Furthermore, after the display screen 2A or 2B in Fig. 25 is displayed, the display screen 2C may be automatically displayed. In this display screen 2C, a recommendation 60H is displayed to prompt the user to perform an input operation to select a heating source.

[0330] On the display screen 2A, the text "Caution: Bumping" is one of the warning symbols 60E. This "bumping" refers to the phenomenon where, when heating a viscous food (liquid) such as curry or stew, the inside of the food overheats above its boiling point, causing sudden, violent boiling. As steam escapes from the heated liquid, hot droplets can fly, creating a dangerous situation. The timing and cause of bumping are said to be the introduction of foreign matter or impact from outside. Therefore, when a metal pot or other food containing food is placed on the top plate 3 and induction heated, caution is advised when stirring the food. The information displayed in this warning is a type of "Standby Common Information" 60N.

[0331] The four display screens, namely, display screen 1 and display screens 2A to 2C shown in Fig. 25, are called "common screens" or "standby initial screens" 16MH. Note that forms other than these four may also be included in the common screen 16MH.

[0332] On display screen 2B, 60E is a warning display that warns that the inside of heating chamber 6 is at a high temperature and to avoid careless contact. If control device 40 detects that heating chamber 6 has not yet cooled down sufficiently after oven cooking has been performed in heating chamber 6, display screen 2 automatically switches to this state. Note that display screens 2A and 2B cannot be displayed simultaneously, but they may be displayed alternately at intervals of several seconds to warn about both the bumping boiling display and the high temperature display. Furthermore, the audio notification unit 50 may also output the warning contents of display screens 2A and 2B in parallel via audio.

[0333] As is clear from display screen 1 to display screens 2A to 2C in Fig. 25, these displays utilize the entire display screen. In other words, rather than displaying only a portion of the first area 22 to third area 24, in order to secure as large a display area as possible, the first area 22 to third area 24 are displayed as an integrated display so that they cannot be distinguished from one another, and the user sees the display as being across the entire central display section 16M.

[0334] Next, FIG. 26 is an enlarged plan view illustrating the operation of the left display part 16L of the cooking appliance 1. As shown in FIG. At step SS4 in Fig. 24, when input key 153L and input key 152L are operated, control menus to be implemented in left heating port 4L are displayed one by one on left display unit 16L. That is, each time input key 152L is pressed, one of the multiple control menus can be selected.

[0335] The control menus that can be selected for the left heating port 4L (in induction heating single cooking mode KM1) include, for example, "Keep Warm," "Boil Water," "Stew," "Frying (Automatic Cooking)," and "Preheat," as shown in Fig. 26. The operating time, heat power, or operating pattern of the left IH coil 9L differs for each control menu.

[0336] Display screen 3A in Fig. 26 shows the case where the "Keep Warm" control menu is selected. Display screen 3B shows the case where the "Deep Fry" control menu is selected. Display screen 3C shows the case where the "Preheat" control menu is selected.

[0337] When the control menu (for the induction heating only cooking mode KM1) is selected using the central IH coil 9M that is responsible for the central heating port 4C on the central display unit 16M, a display screen like the display screen 3A shown in Fig. 26 is displayed. In this case, the display screen of the central display unit 16M has a display format like the display screen 3A, and this screen is called a "third specific screen" 16M3.

[0338] FIG. 27 illustrates the operation steps of the control device 40 of the cooking appliance 1 from when the cooking appliance 1 is started until just before cooking starts.

[0339] In Figure 27, when the operation button 20A of the main power switch 20 is pressed and the standby initial screen 16MH is displayed on the central display unit 16M, it is determined whether recipe information (cooking condition data) has been acquired from an external device (the communication terminal device 200 or the cloud server 300) (step SU2).

[0340] In step SU3, the control device 40 compares the latest state of the cooking appliance 1 with the latest state and determines whether the state satisfies the permission conditions 1 and 2.

[0341] If it is determined that permission conditions 1 and 2 are simultaneously satisfied (SU6), the identification information included in the recipe information (cooking condition data) acquired from the external device (the communication terminal 200 or the cloud server 300) is displayed on the central display unit 16M. In this case, the identification information 167 (for example, "Name: Hamburger") is displayed on the first specific screen 16M1 (step SU7).

[0342] The identification information 167 (for example, "Name: Hamburger") is displayed as shown in FIG. 28. An operation recommendation display section 170 is also displayed. This prompts the user to press the input key 151M to start cooking. The audio notification section 50 also notifies the user, for example, "Press the start key to start cooking" (step SU8).

[0343] At the stage of step SU8, the user may operate an input key (for example, 156M or 155M) that can select a control condition (for example, heating power value) to set the heating power, heating time, etc. as appropriate.

[0344] On the other hand, a case where, at the stage of step SU3, the control device 40 compares the latest state of the cooking appliance 1 and determines that the state does not satisfy the permission conditions 1 and 2 (step SU4) will be described.

[0345] The content of the standby initial screen 16HM in the central display section 16M is partially changed, and a message is displayed in text indicating that the recipe information (cooking condition data) acquired from the external device cannot be executed with the current cooking appliance 1. The same message is also notified by voice from the voice notification section 50 (step SU5). Then, the process returns to step SU1. This operation corresponds to the operation of step ST8 described in FIG. 22.

[0346] Next, FIG. 28 will be described. FIG. 28 is an enlarged plan view showing the same parts as those described in FIG. 16, ie, central operation unit 15M and central display unit 16M.

[0347] 28, 173 is an external recipe identification section that indicates that the recipe information (cooking condition data) is obtained from an external device (the communication terminal 200 or the cloud server 300). The text "Received recipe" is displayed, making it easy to see that the cooking menu displayed on this first specific screen 16M1 has been obtained from an external device.

[0348] In Figure 28, light-emitting unit 21M corresponding to input key 151M is in a standby state where the heating operation can be started at any time. To indicate this, it is flashing to prompt the user to operate input key 151M. The dashed circle indicates that light-emitting unit 21M is flashing.

[0349] 28, a star-shaped figure is drawn at the position of light-emitting unit 21M. This figure means that the input functions of the input keys (e.g., 156M, 157M) arranged in front of light-emitting unit 21M are valid, and that by touching them at this point, the heat, heating time, etc. can be adjusted.

[0350] 28, light-emitting units 21M corresponding to input keys 157M and 156M are emitting light. In other words, the user can select either heating unit specification unit 171L for selecting cooking using left heating port 4L, or heating unit specification unit 171R for selecting cooking using right heating port 4R.

[0351] Recipe information (cooking condition data) acquired from an external device is displayed preferentially on the first specific screen 16M1 by displaying the external recipe identification section 173. That is, the identification information 167 of the received recipe information (cooking condition data) is displayed in the "display position B" on the first specific screen 16M1. Therefore, by immediately pressing the input key 151M as shown in FIG. 28, cooking in the cooperative cooking mode KM3 can be started.

[0352] As described above, there are two types of recipe information (cooking condition data) acquired from an external device (the communication terminal 200 or the cloud server 300): one in which cooking is limited to specific heating elements (right heating port 4R, center heating port 4C, left heating port 4L), and one in which cooking can be performed by specifying the range of heating elements that can be used according to the user's wishes. Therefore, even when a user uses recipe information acquired from an external source, usability is not impaired.

[0353] Next, we will explain Fig. 29. Fig. 29 is an explanatory diagram showing the relationship between the cooking steps of the collaborative cooking menu and the operations on the input operation unit. In the example of FIG. 29, the cooperative cooking menu is made up of three cooking steps: cooking step 1, cooking step 2, and cooking step 3.

[0354] 29, the cooking condition data is specified in a predetermined computer program format to wait for input from input key 151M to start induction heating at right heating port 4R (or left heating port 4L), and to stop the heating operation when input from input key 153R (153L) is made, or to stop the heating operation when certain conditions (continuous cooking time or reaching of target temperature) are met. Control conditions such as heat power may also be specified.

[0355] The program included in the cooking condition data defines heating pause periods P3 and P5, which will be described later, but does not define the duration of these heating pause periods P3 and P5. However, to prevent cooking from being interrupted for an excessively long time, it is possible to include a process that counts the elapsed time from the end of cooking step 1 and cooking step 2, for example, and issues an alarm or forcibly stops the execution of the cooking menu if, for example, 30 minutes have passed.

[0356] In the example of cooking condition data in Figure 29, cooking process 1 is performed using an induction heating source (first heating means HM1), cooking process 2 is performed using a microwave heating source (second heating means HM2), and finally cooking process 3 is provided in which the food to be cooked is moved onto top plate 3 and final induction heating is performed to compensate for insufficient heating.

[0357] In addition, in this cooking device 1, a measure is added to prevent the setting of cooking modes, control conditions, etc. from being inadvertently changed in response to an external command signal.

[0358] In the example of Figure 29, the first heating means HM1 is operated first, and after that heating operation is completed, the second heating means HM2 is operated, but the radiant heat heating means 12 may also be operated as the third heating means simultaneously with the second heating means HM2.

[0359] As shown in FIG. 29, the collaborative cooking menu shown here consists of four steps. P1 is the first stage (preparation period), which is the period from when input key 153M is operated to execute the cooperative cooking menu until the (induction) heating cooking operation is started by input key 153R.

[0360] When the input key 153M is operated, if the "permission condition" as described above is satisfied, the control device 40 displays the first specific screen 16M1. Note that the first specific screen 16M1 is not shown in Fig. 29.

[0361] When the first specific screen 16M1 is displayed, one of the linked cooking menus can be selected by operating input keys 154M and 155M. After that, by operating input key 153R, the system transitions to linked cooking mode and proceeds to the heating cooking step P2.

[0362] When the first specific screen 16M1 is displayed, if the identification information 167 of the user's desired collaborative cooking menu is displayed in a predetermined position on the first specific screen 16M1 (default display), there is no need to operate the input keys 154M and 155M.

[0363] P2 is the cooking period (cooking step 1) by the first heating means HM1. In this cooking step 1, when an appropriate food to be cooked, such as a metal pot, is placed on the right heating port 4R and the input key 153R is pressed, the cooking operation is started.

[0364] At the stage when cooking step 1 is started, the control device 40 has already finished determining whether the permission conditions are met, and therefore knows which heating section of the first heating means HM1 (induction heating means) is in use. In other words, it knows the usage status of both the right heating port 4R and the left heating port 4L. Therefore, as a default setting, the control device 40 determines to use the "right heating section" 4R in cooking step 3 of the cooperative cooking mode, and occupies this right heating port 4R.

[0365] Cooking step 1 is basically predetermined by the operation program of the linked cooking menu. For example, when the standard heating time has elapsed, a notification is made by the audio notification unit 50, and the first specific screen 16M1 also displays a message such as "X minutes will soon have elapsed." In other words, the user is notified that cooking step 1 is nearing completion. To end cooking step 1, the user simply presses the input key 153R once.

[0366] P3 is a heating pause period during which cooking step 1 by the first heating means HM1 is temporarily stopped and cooking step 2 by the second heating means HM2 is started.

[0367] This pause period P3 is a period required to check the degree of heating of the food in cooking step 1, to add seasonings, or to add another food and perform cooking step 2. It is also a period required to move the food to heating chamber 6. The heating pause step P3 ends when the input key 151M is pressed, and the process proceeds to the cooking step 2 of P4.

[0368] This cooking process 2 is started when the control device 40 confirms that the door 7 has been opened once during the pause period P3 and then closed. The door open / close signal from the open / close detection unit 10 described in the first embodiment is used.

[0369] Cooking step 2 basically ends automatically when the heating time predetermined by the operation program of the linked cooking menu has elapsed or when the temperature of the food to be cooked reaches a set value (e.g., 90°C). For example, in one linked cooking menu, heating begins with a microwave output of 500 W. Furthermore, if the user opens door 7 at any time, microwave irradiation is instantly stopped and the heating operation is stopped.

[0370] In cooking step 2 of P4, the user may be able to individually set control conditions (e.g., cooking time and target temperature) by operating at least one of the four input keys 156M to 159M, but depending on the cooking menu, the user may not be able to change the control conditions.

[0371] 29 shows the case where the input key 152M on the central operation unit 15M is pressed to end cooking process 2. When the input key 152M is pressed to command the cooking to stop, cooking process 2 ends and the process proceeds to the heating pause period P5.

[0372] During this heating pause period P5, the user opens the door 7, removes the food to be cooked from inside the heating chamber 6, and places it on the top plate 3. The food to be cooked is placed inside a heated object such as a metal pot. Then, when the input key 153R for the right heating unit 4 is pressed to command the start of cooking, the heating pause step P5 ends and the process proceeds to the heating cooking period P6 (the "cooking step 3" of induction heating).

[0373] This heating pause period P5 is the period required to check the degree of heating of the food in cooking step 2, add seasonings, or add another food to be cooked and proceed to the next cooking step 3. For example, in cooking step 2, only frozen food can be heated, and in cooking step 3, the food can be immersed in seasonings or cooking liquid, or a food that has been preheated separately can be added to the same food. This broadens the range of cooking options.

[0374] P6 switches from cooking step 2 using the second heating means HM2 (microwave heating source) to cooking step 3 using the first heating means HM1 (in this case, induction heating means, for example, the right heating port 4R). In this cooking step 3, when cooking using the right heating port 4R as described above, the user can individually set control conditions (for example, cooking time and target temperature) by operating input keys 154R and 155R (see Figure 8).

[0375] Furthermore, if cooking step 3 is performed using left heating port 4L, the user can individually set control conditions (for example, cooking time and target temperature) by operating input keys 154L and 155L.

[0376] Then, when input key 153R is pressed to command stopping of cooking, cooking process 3 ends and operation of linked cooking mode KM3 ends. In the case of timer cooking, induction heating cooking ends automatically when the time has elapsed, and cooking process 3 ends.

[0377] 29, the right operation unit 15R of the right heating port 4R becomes unusable from the point at which the start of cooking is decided using the input key 151M of the central operation unit 15M, not when the linked cooking menu is selected, i.e., when the identification information 167 indicating the name of the cooking on the linked cooking menu is displayed on the central display unit 16M. Note that if the left heating port 4L is set as the default setting, the left heating port 4L will be occupied.

[0378] As is clear from the above description, the control device 40 performs the following function restriction process. (1) The input signal from the right operation unit 15R is disabled or input is restricted. For example, the input functions of the input keys 151R and 152R are disabled. As a result, during the cooking period (cooking step 1) to cooking period (cooking step 3), the right heating port 4R cannot be used (input) except when input is required in the linked cooking mode KM3. (2) Even when the heating cooking period (cooking step 1) begins, the left operating unit 15L can be used (the input signal from the left operating unit 15L is not invalidated).

[0379] In this way, when the heating cooking period (cooking step 1) begins, the control device 40 moves from the cooking step 1 stage to a state in which only the right heating port 4R for cooking step 3 is occupied.

[0380] Therefore, the right heating port 4R is "occupied" by the selection of the linked cooking menu. Also, when viewed from the perspective of the first heating means HM1 as a whole, the use of only a portion (the right side) of the three heating sections is "restricted."

[0381] Even after the heating cooking period (cooking step 1) ends, the restricted state of the right heating port 4R is not released. In addition, during the cooking process 1, the first specific screen 16M1 is displayed, and the user can easily understand that the cooperative cooking mode has been entered, so the first heating means HM1 and the second heating means HM2 are not restricted from executing other cooking menus. This also applies to the heating pause period P3 to cooking process 2.

[0382] Furthermore, even if the control device 40 detects that the door 7 has changed from an open state to a closed state before the start of the heating cooking period (cooking process 2), if the temperature inside the heating chamber 6 is higher than the reference value, there is a concern that the control device 40, the non-contact (infrared) sensor 13, and thermistor sensor 14 may mistakenly recognize the abnormally high temperature in the heating chamber 6 as indicating that cooking has been completed even before cooking has started. Therefore, if the temperature of the heating chamber 6 is too high before the start of the heating cooking period (cooking process 1), the first specific screen 15M1 displays a message that "the second heating means HM2 (microwave heating means) cannot be used immediately due to high temperature."

[0383] The periods indicated by thick arrows in FIG. 29 are the reception restriction period for one cooking condition data (recipe data) and the acquisition restriction period for additional cooking condition data (recipe data).

[0384] After the input key 153M is touched once and the first specific screen 16M1 is displayed, the limiting operation by the limiting unit 55 is performed as follows. It should be noted that the reception and transmission functions of the communication unit 51 are enabled at the time the first specific screen 16M1 is displayed (before that, at least the reception function is disabled).

[0385] That is, the limiting unit 55 built into the control device 40 operates as follows. As shown in Figure 29, it is not possible to change a specific linked cooking menu A obtained from an external device to another linked cooking menu B (for example, "hamburger steak"). To change the menu, it is necessary to operate the input key 152M to cancel the linked cooking mode KM3 and return to the initial standby screen 16MH.

[0386] In other words, once the time limit indicated by the thick arrow in Fig. 29 is reached, the cooking using the specific linked cooking menu A obtained from an external device can be canceled at any time by operating the input key 152M. Once the cancellation operation is performed, the display returns to the initial standby screen 16MH, and it is necessary to touch the input key 153M again in this state.

[0387] Furthermore, after the input key 153M is touched for a specific linked cooking menu A obtained from outside, the control device 40 cannot acquire cooking condition data (recipe data) for another linked cooking menu C until all cooking processes are completed.

[0388] In other words, when the limited period indicated by the thick arrow in Figure 29 begins, by operating input key 151M, it is possible to decide to start cooking in collaborative cooking mode KM3, and to perform cooking using the cooking condition data (recipe data) of the specific collaborative cooking menu A obtained immediately before this decision, but until all cooking steps of this cooking menu A are completed, it is not possible to obtain any additional cooking condition data (recipe data) from outside (such as smartphone 200).

[0389] Summary of embodiment 1. As is clear from the above description, in the first embodiment, the cooking device 1 according to the first disclosure is disclosed as follows. That is, the cooking device 1 according to the first disclosure is a first heating means HM1 for heating an object to be heated at a first location (above the top plate 3); a second heating means HM2 for heating the food to be cooked in a second location (heating chamber 6) separate from the first location; an input operation unit 15 for receiving instructions from a user; A communication unit 51 that receives cooking condition data 2 (CD2, CD4, CD5, CD6) from an external device; a control device 40 that controls the first heating means HM1, the second heating means HM2, and the communication unit 51, The control device 40 includes a heating control unit 43 that executes a cooperative cooking mode KM3 in which the first heating means HM1 and the second heating means HM2 are driven with a time lag based on cooking condition data 1; a data acquisition unit 53 that acquires cooking condition data 2 via the communication unit 51 in order to execute heating cooking in the cooperative cooking mode for a specific food; and a restriction unit 55 that restricts the acquisition of the cooking condition data 2 by the data acquisition unit 53 via the communication unit 51 during a waiting period before starting cooking in the cooperative cooking mode KM3 (i.e., a "preparation period" P1 before "cooking step 1" shown in FIG. 29). The restriction unit 55 is configured to restrict the acquisition of new cooking condition data from the communication unit 51 until the cooking process of the cooking menu to which the acquired cooking condition data 2 is applied is completed.

[0390] This prevents another cooking menu (including the control menu for the combined cooking mode or the control menu for the single cooking mode) from being accidentally received during coordinated cooking, and allows the cooking menu of the cooking condition data 2 to be stably executed. Furthermore, it is possible to prevent the operation of the control device 40 from being affected or to prevent the user from being confused or misled, due to the cooking condition data for another cooking menu being inadvertently received during the cooking process.

[0391] Furthermore, in this first embodiment, the cooking device 1 according to the second disclosure is disclosed as follows. That is, a first heating means HM1 for heating an object to be heated placed on the top plate 3; a second heating means HM2 for heating the food to be cooked inside the heating chamber 6; a third heating means HM3 that heats the heating chamber 6 and has a heating principle different from that of the second heating means HM2; an input operation unit 15 for receiving instructions from a user; a communication unit 51 that receives cooking condition data (CD2, CD4, CD5, CD6) from the outside via wireless communication; a control device (40) that controls the first heating means, the second heating means, the third heating means, and the communication unit (51), The control device 40 has a function of executing an integrated cooking mode KM3 in which the first heating means HM1 and at least one of the second heating means HM2 and the third heating means HM3 are driven with a time lag; The control device 40 has a data acquisition unit 53 that acquires the cooking condition data (CD2, CD4, CD5, CD6) via the communication unit 51 in order to execute the cooperative cooking mode KM3 for a specific food item (e.g., "hamburger steak"), and a restriction unit 55 that restricts the acquisition of the cooking condition data by the data acquisition unit 53 via the communication unit 51 from a preparation period before starting cooking in the cooperative cooking mode KM3 (i.e., the "preparation period" P1 before "cooking step 1" shown in FIG. 29). The heating cooker 1 is characterized in that, when the data acquisition unit 53 acquires the cooking condition data, the restriction unit 55 restricts the acquisition of new cooking condition data from the communication unit 51 until the cooking process of the cooking menu to which the cooking condition data is applied is completed.

[0392] With this configuration, three heating means can be selected to perform cooking in the single cooking mode KM1, the combined cooking mode KM2, and the cooperative cooking mode KM3, thereby providing a cooking device that can handle a wide range of cooking methods.

[0393] Furthermore, because of the restriction unit 55, once cooking condition data (recipe data) for one specific coordinated cooking menu A is acquired, the control device 40 will not inadvertently acquire cooking condition data (recipe data) for another coordinated cooking menu C immediately before the start of a cooking process or during the cooking process. Therefore, for example, another cooking menu (including a control menu for combined cooking mode or a control menu for single cooking mode) will not be inadvertently received during coordinated cooking. Therefore, there is no concern about user confusion or operational interference with the cooker 1 due to reception.

[0394] Furthermore, in the heating cooker 1 of embodiment 1, the input operation unit 15 is disclosed to have separate input keys 153L and 153R for selecting the single cooking mode KM1, input keys 154M and 155M for selecting the combined cooking mode KM2, and input key 153M for selecting the linked cooking mode KM3.

[0395] With this configuration, the three cooking modes can be selected using the respective input keys (input means), so that the user's operability can be improved even in a cooking device 1 with an increased number of heat sources.

[0396] As is clear from the above description, in the first embodiment, the cooking device 1 according to the third disclosure is disclosed as follows. a first heating means HM1 for heating an object to be heated at a first location (above the top plate 3); a second heating means HM2 for heating the food to be cooked in a second location (heating chamber 6) separate from the first location; an input operation unit 15 for receiving instructions from a user; A communication unit 51 that receives cooking condition data 2 (CD2, CD4, CD5, CD6) from an external device; a control device 40 that controls the first heating means HM1, the second heating means HM2, and the communication unit 51, The control device 40 includes a heating control unit 43 that executes a cooperative cooking mode KM3 in which the first heating means HM1 and the second heating means HM2 are driven with a time lag based on cooking condition data 1, a data acquisition unit 53 that acquires cooking condition data 2 via the communication unit 51 in order to execute heating cooking in the cooperative cooking mode for a specific food, and a restriction unit 55 that restricts the data acquisition unit 53 from acquiring the cooking condition data 2 via the communication unit 51 from a preparation period P1 before cooking in the cooperative cooking mode KM3 is started (i.e., before "cooking step 1" shown in FIG. 29 ). The limiting unit 55 limits acquisition of new cooking condition data from the communication unit 51 until the cooking process of the cooking menu to which the acquired cooking condition data 2 is applied is completed, After the cooking condition data 2 is acquired, if the cooperative cooking mode KM3 is canceled by the input operation unit 15 before the cooking process is started, the data acquisition unit 53 can acquire the cooking condition data 2 again.

[0397] This prevents another cooking menu (including the control menu for the combined cooking mode or the control menu for the single cooking mode) from being accidentally received during coordinated cooking, and allows the cooking menu of the cooking condition data 2 to be stably executed. Furthermore, it is possible to prevent the operation of the control device 40 from being affected or to prevent the user from being confused or misled, due to the cooking condition data for another cooking menu being inadvertently received during the cooking process.

[0398] Furthermore, when the cooperative cooking mode KM3 is canceled, the cooking condition data 2 that was previously acquired and not used for cooking can be canceled, and the desired cooking condition data 2 can be acquired again, thereby preventing the user from becoming confused about the cooking condition data.

[0399] Furthermore, in this first embodiment, the cooking device 1 according to the sixth disclosure is disclosed in the following form. That is, a first heating means HM1 for heating an object to be heated in an upper portion of the main body 2; a second heating means HM2 for heating food contained in a heating chamber 6 disposed inside the main body 2; a third heating means HM3 that heats the heating chamber 6 by a heating principle different from that of the second heating means HM2; an input operation unit 15; a communication unit 51 for wirelessly communicating with the outside; A display unit 16; a control device 40 that controls the first, second, and third heating means HM1, HM2, and HM3, respectively; The control device 40 has a function of performing a cooperative cooking mode KM3, a composite cooking mode KM2, and a single cooking mode KM1, After the main power is turned on by the input operation unit 15, the control device 40 (1) The display unit 16 displays the standby initial screen (common screen) 16MH, (2) When the input keys 153M, 154M, 155M for selecting either the linked cooking mode KM3 or the combined cooking mode KM2 are operated, the limiting unit 55 limits the acquisition and use of cooking condition data acquired from the communication unit 51, (3) When the selection input keys 153M, 154M, and 155M are operated, the display of the initial screen (common screen) 16MH changes to the display of the first specific screen 16M1 or the second specific screen 2, (4) While the first specific screen or the second specific screen is displayed, the device transitions to a standby state for receiving a cooking start command from the input operation unit 15, (5) During the standby state (preparation period P1), acquisition of cooking condition data from the communication unit 51 is restricted (not permitted).

[0400] With this configuration, once the standby initial screen (common screen) 16MH is displayed, it can be easily understood that by operating the selection input keys 153M, 154M, and 155M thereafter, the first specific screen 16M1 and the second specific screen 16M2 dedicated to the linked cooking mode and the combined cooking mode can be displayed, and cooking condition data can be acquired from the outside. This is expected to prevent confusion or misunderstanding in the user's input operations from immediately after the main power is turned on until cooking begins, thereby improving usability.

[0401] Embodiment 2 30 to 49 show a cooking device and a cooking system according to the second embodiment. FIG. 30 is a block diagram showing the main functional configuration of a (built-in combination) cooking appliance 1 according to embodiment 2. FIG. 31 is a block diagram showing the main functional configuration of a communication terminal. FIG. 32 is an explanatory diagram illustrating the operation of the cooking appliance of FIG. 30 when cooking in the cooperative cooking mode. FIG. 33 is an enlarged plan view illustrating the operation of the central operation unit and central display unit of the cooking appliance of FIG. 30. FIG. 34 is an explanatory diagram 1 illustrating the operation of the central operation unit and central display unit of the cooking appliance of FIG. 30. FIG. 35 is an explanatory diagram 2 illustrating the operation of the central operation unit and central display unit of the cooking appliance of FIG. 30. FIG. 36 is an explanatory diagram 3 illustrating the operation of the central operation unit and central display unit of the cooking appliance of FIG. 30. FIG. 37 is an explanatory diagram 4 illustrating the operation of the central operation unit and central display unit of the cooking appliance of FIG. 30. FIG. 38 is an explanatory diagram 1 illustrating the relationship between the cooking steps of a cooperative cooking menu and the operation of the input operation unit. FIG. 39 is an explanatory diagram 2 illustrating the relationship between the cooking steps of a cooperative cooking menu and the operation of the input operation unit. The same or corresponding parts as those in the configuration of the first embodiment explained in FIGS. 1 to 29 are denoted by the same reference numerals.

[0402] In the second embodiment, the configuration of the cooking device 1 is changed, and the function of the restriction unit 55 that restricts part of the acquisition of cooking condition data is different from that of the first embodiment.

[0403] An explanation will be given to Fig. 30. Reference numeral 43 denotes a heating control section that performs integrated control of the entire cooking appliance 1, and is mainly composed of a microcomputer. 55 is a restriction unit that restricts some of the input functions and display functions of the heating cooker 1 when cooking condition data (including the above-mentioned "display condition data") is acquired from an external communication terminal device 200, etc., and issues various control commands in response to the operation of the data acquisition unit 53 acquiring cooking condition data from the smartphone 200 or the cloud server 300 via the communication unit 51.

[0404] Next, the communication terminal device 200 shown in FIG. 31 will be described. A communication terminal device 200 such as a smartphone has a transmitting unit and a receiving unit 210, a communication control unit 211, a central processing unit (CPU) 212, a ROM and a RAM 213, a speaker 214, a touch-type operation unit 215, a terminal side display unit 216 having a display screen, a cooking appliance database (storage unit) 217, an attitude detection unit 218, a remote operation information generation unit 219, and a storage unit 220. The transmitting unit and receiving unit 210 has an NFC input / output unit 221 for short-range wireless communication.

[0405] 222 is a voice input unit that converts the voice of the user or the like into an input signal. The touch-type operation unit 215, terminal display unit 216, and voice input unit 222 are integrated in hardware to form a display operation unit 225. Note that a search unit that analyzes the voice signal from the voice input unit 222 and performs term search, information search, etc. is not shown. The search unit may be provided inside the communication terminal device 200, or may be provided in an external cloud server 300, so that the search function is provided outside the communication terminal device 200.

[0406] The attitude detection unit 218 is equipped with various sensors such as a gyro sensor, an acceleration sensor, and a gravity sensor, and can detect the tilt and orientation of the communication terminal 200. As a result, a signal indicating the up-down direction of the communication terminal 200 is output to the central processing unit 212.

[0407] The central processing unit 212 receives a detection signal from the orientation detection unit 218 and controls the display orientation of the terminal display unit 216 . The central processing unit 212 inputs the signal received from the communication unit 51 of the cooking appliance 1 to the remote operation information generation unit 219.

[0408] The central processing unit 212 has a cooking condition data acquisition unit 230, a cooking condition data transmission unit 231, and a terminal-side recipe selection unit 232. The cooking condition data acquisition unit 230, the cooking condition data transmission unit 231, and the terminal-side recipe selection unit 232 may all be functionally realized by a single computer program, or may be configured by separate control circuits.

[0409] The cooking appliance database 217 holds "notification data" 223 of the cooking appliance 1 in order to generate notification information (including image information) for the central display unit 16M and the audio notification unit 50 of the cooking appliance 1. The cooker database 217 also holds “remote control data” 224 for the control device 40 of the cooker 1 .

[0410] The notification data 223 and the remote control data 224 may be stored in this communication terminal device 200 from the beginning, or may be acquired by connecting to a cloud server 300, which is an information providing means, via the network 201 (202) and downloading the data from the cloud server 300. In other words, the cooking appliance database 217 does not need to be constructed by fixed storage, and may be in a form in which information is acquired as needed and temporarily stored in a volatile memory.

[0411] The cooking appliance database 217 may acquire cooking condition data for various cooking methods performed by the cooking appliance 1, particularly cooking menus (e.g., "Ratatouille") that can be used in the collaborative cooking mode KM3, from the cloud server 300 or from other communication terminal devices 200 via the NFC input / output unit 221 (see Figure 31).

[0412] The remote operation information generation unit 224 processes the signal acquired from the cooking appliance 1 via the central processing unit 212 and the input signal from the display operation unit 225, and generates a remote operation command (information) RS for the cooking appliance 1.

[0413] The "remote operation command (information)" RS here includes commands (information) related to input operations of the cooking appliance 1 corresponding to all cooking modes including the cooperative cooking mode KM3 and the combined cooking mode KM2, display commands (information) for the central display unit 16M in the cooperative cooking mode, combined cooking mode, etc., and display commands (information) related to the right display unit 16R and the left display unit 16L. However, it does not include information that serves as a command to start a heating operation in all cooking modes including the cooperative cooking mode KM3. Therefore, the cooking appliance 1 does not receive a command to start a heating operation by this remote operation command.

[0414] The "remote operation command" RS may not include the display command for the central display unit 16M and the display commands for the right display unit 16R and the left display unit 16L. In addition, command information for the functions that can be set using the function setting key 151KP cannot be transmitted from the communication terminal 200, and cannot be generated by the communication terminal 200.

[0415] The central processing unit 212 executes the overall processing of the communication terminal device 200 in accordance with a control program stored in ROM / RAM, and reads data required in the process of executing the processing from ROM / RAM, and stores data generated in the process of executing the processing in the ROM / RAM.

[0416] The storage unit 220 is a non-volatile semiconductor memory that can store information about the cooking appliance 1 read from the transmission unit and the reception unit 210. For example, the storage unit 220 is used to temporarily store the cooking condition data (also called "recipe data") for a specific cooking menu that has been downloaded (read) from the cloud server 300.

[0417] When the user touches a specific portion of the terminal display unit 216 of the communication terminal 200, the remote operation information generating unit 219 generates remote operation information based on the touch signal. The remote control information is transmitted from the transmitting and receiving unit 210 to the cooking appliance 1.

[0418] If the cooking appliance 1 has already been supplied with power and started up, the control device 40 of the cooking appliance 1 treats the received remote operation information as cooking mode input operation information. For example, when a remote operation signal related to the cooperative cooking mode KM3 is received, the standby initial screen 16MH of the central display unit 16M transitions to a selection screen (first specific screen 16M1) for one cooking menu item (e.g., hamburger steak) in the cooperative cooking mode KM3. However, this does not mean that the cooking appliance 1 operates unconditionally in response to the remote operation information of the communication terminal device 200. This will be described in FIG. 32.

[0419] On the other hand, on the side of communication terminal 200 that has transmitted the remote operation information, the display on terminal display unit 216 changes based on the remote operation information. In other words, the content of the display screen of terminal display unit 216 on display operation unit 225 of communication terminal 200 and the display content on central display unit 16M of cooking appliance 1 change in accordance with similar operation procedures, but the state of the change is not transmitted to cooking appliance 1 in real time one by one.

[0420] Even if a remote operation command is generated in communication terminal device 200, it is only after a cooking mode confirmation signal is transmitted that it is recognized as a regular remote operation signal by cooking appliance 1. In other words, the remote operation information from communication terminal device 200 is transmitted all at once when a predetermined confirmation key is pressed on communication terminal device 200 to confirm the cooking mode.

[0421] Therefore, the cooking condition data (recipe data) for a cooking menu (e.g., hamburger steak) in the cooperative cooking mode KM3 includes data specifying the heating means from cooking step 1 to the final cooking step, and data on default control conditions (e.g., heat level, heat value, heating time, etc., but not limited to these) all transmitted together. In other words, the data also includes data on detailed control conditions that the user can set arbitrarily on the first specific screen 16M1.

[0422] Next, a description will be given of Fig. 32. Fig. 32 is a diagram illustrating the operation when cooking in the cooperative cooking mode. In FIG. 32, the operation procedures, related input keys, display screens, and characteristic points regarding the operations are listed in three vertical columns.

[0423] First, when the operation button (key) 20A of the main power switch 20 is pressed, main power is supplied to the control device 40, and if the control device 40 detects no abnormalities as a result of its self-diagnosis, the central display unit 16M and the input operation unit 15 are activated. The heating power display units 17 (left heating power display unit 17L, central heating power display unit 17M, right heating power display unit 17R) are also activated.

[0424] The central display section 16M displays an initial standby screen 16MH. A two-dimensional code 60B is displayed on the standby initial screen 16MH. When the communication terminal 200 optically reads the two-dimensional code 60B, it can connect to the recipe information providing server 301 that stores information on various cooking recipes, i.e., various cooking condition data. Therefore, the communication terminal 200 can obtain the cooking condition data for the desired cooking.

[0425] In this second embodiment, the communication terminal device 200 can directly communicate wirelessly with the cooking appliance 1. The cooking appliance 1 and the communication terminal device 200 are configured to be automatically connected when they are within a communication range.

[0426] The communication method used between the communication terminal device 200 and the cooking appliance 1 is Bluetooth (registered trademark), which is one of the short-range wireless communication standards. A wireless router 340 (not shown) is installed between the communication terminal device 200 and the cloud server 300. A wireless LAN communication method such as WiFi (registered trademark) is used between the wireless router (not shown) and the communication terminal device 200.

[0427] First, mutual authentication is performed between the communication terminal device 200 and the cooking appliance 1, so when the cooking appliance 1 is started up, if the cooking appliance 1 transmits a signal for automatic connection (also called a "scan signal"), mutual communication for automatic connection is performed between the cooking appliance 1 and the communication terminal device 200. The scan signal may also be transmitted from the communication terminal device 200 side.

[0428] Once the connection between the cooking appliance 1 and the communication terminal device 200 is established, the cooking appliance 1 and the communication terminal device 200 continue to be able to directly communicate wirelessly with each other. If the communication terminal device 200 moves with the user and becomes farther away from the cooking appliance 1, communication may become temporarily unavailable, but the connection will be automatically restored when the communication range (distance) returns.

[0429] During the period from the time when the standby initial screen 16MH is displayed until the input key 153M (to select the collaborative cooking mode KM3) is pressed, acquisition of cooking condition data CD2, CD4, and CD6 from the communication terminal device 200 is basically prohibited.

[0430] Furthermore, during the period from when the main power switch 20 is turned on until the standby initial screen 16MH is displayed, the cooking condition data CD2, CD4, and CD6 cannot be acquired from the communication terminal 200 at all.

[0431] FIG. 38, which will be described later, shows an example in which the reception restriction on the cooking condition data CD2, CD4, and CD6 is lifted from the point in time when the input key 153M is pressed.

[0432] FIG. 33 shows an example in which the display screen of FIG. 32 is slightly modified. When cooking condition data is received from an external device, an example such as "Receiving recipe from an external device" is displayed in text on the initial standby screen 16MH as shown in FIG.

[0433] In contrast to this, FIG. 33 shows an example in which the display is switched to a dedicated reception operation display screen 16MM, which will be explained in FIG.

[0434] FIG. 34 is a plan view showing the initial standby screen 16MH, which shows the state immediately after the main power switch 20 is turned on.

[0435] Next, as shown in FIG. 35, when the input key 153M is pressed, information (identification information 167) of each cooking menu in the cooperative cooking mode is displayed on the display section 16M.

[0436] 35, light emitting units 21M corresponding to input keys 154 to 157 emit light as indicated by a star shape. That is, the cooking menu and control conditions can be changed by the user using these input keys 154 to 157.

[0437] However, the following describes a case where the user's desired dish, for example, "ratatouille," is not available in the cooking menu database held by the cooking appliance 1. "Ratatouille" is a dish that originated in southern France, in which several kinds of vegetables, such as zucchini, onion, and bell pepper, are sliced ​​and sautéed in olive oil with tomatoes and herbs.

[0438] Acquisition of the cooking condition data for the above-mentioned "Ratatouille" by the communication terminal device 200 will be described. Using the voice input unit 222 or the touch-type operation unit 215, the above-mentioned "Ratatouille" is specified in the terminal side recipe selection unit 232, and the cloud server 300 is accessed to obtain the cooking condition data for "Ratatouille" in the cooking condition data acquisition unit 230.

[0439] The acquired cooking condition data for "Ratatouille" is temporarily stored in the storage unit 220. The display unit 216 on the terminal side displays a message indicating that the cooking condition data for "Ratatouille" has been successfully downloaded, and prompts the user to decide whether or not to send the data.

[0440] Therefore, when the user operates the display operation unit 225 (or inputs voice via the voice input unit 222) to instruct the cooking condition data transmission unit 231 to transmit, the central processing unit 212 transmits the cooking condition data for "Ratatouille" to the cooker 1. Note that, together with transmitting this cooking condition data, "notification data" 223 for the cooker 1 and "remote control data" 224 for the control device 40 of the cooker 1 are also transmitted.

[0441] As shown in Fig. 32, after the input key 153M is pressed, the control device 40 allows the cooking condition data for each cooking menu in the cooperative cooking mode to be received by the cooking appliance 1. However, as shown in Fig. 32, the display does not immediately switch to the first specific screen 16M1. Therefore, the operation of receiving the cooking condition data continues while the standby initial screen 16MH is displayed.

[0442] FIG. 33 shows an example in which the configuration of FIG. 32 is slightly modified. The example in Fig. 33 shows another example of a display that indicates that the cooking condition data for "Ratatouille" is being received from the communication terminal 200. As shown in Fig. 33, the initial standby screen 16MH is switched to a receiving operation display screen 16MM that indicates that a recipe is being received from an external device. The receiving operation display screen 16MM will be described later with reference to Fig. 36.

[0443] 30 starts receiving cooking condition data via communication unit 51 when input key 153M is pressed. If any cooking condition data is received, it is temporarily stored in a predetermined storage area in cooking condition data storage unit 42. Reception of notification data 223 and remote control data 224 is also permitted, and these are linked to the cooking condition data for "Ratatouille" (processed so that they can be identified in a one-to-one relationship) and temporarily stored in storage unit 42.

[0444] Fig. 34 is an enlarged plan view illustrating the operation of the central operation unit 15M and central display unit 16M of the cooking appliance 1. The figure shows a state in which one display screen 1 (see Fig. 25) of the standby initial screen 16MH is displayed. The dashed circle surrounding the input key 153M indicates that the portion of this input key 153M is illuminated by a light-emitting element (not shown), such as an LED. In other words, the user is encouraged to press this input key 153M.

[0445] Next, we will explain Figure 35. In FIG. 35, CD9 is "cooking execution data" that is automatically transmitted to the cloud server 300 via the network 205 immediately after the cooking appliance 1 has finished cooking.

[0446] Here, the "cooking execution data" is useful information that is used by the cloud server 300 to analyze the results of cooking, long-term history, changes, and the like.

[0447] In FIG. 35, the cooking execution data CD9 is illustrated as being sent only to the cloud server 300, but it may be set in advance on the cooker 1 side so that it is sent to the communication terminal device 200 as well.

[0448] Figure 36 shows an example of a specific display screen that indicates that the cooking condition data for "Ratatouille" is being received from the communication terminal 200. As shown in Figure 36(B), the initial standby screen 16MH is switched to a receiving operation display screen 16MM that indicates that a recipe is being received from an external device.

[0449] FIG. 36(A) is a schematic diagram showing an enlarged view of the reception operation display screen 16MM. In FIG. 36(A), 16F denotes a plurality of progress marks that appear in the reception operation display screen 16MM according to the progress of the reception operation.

[0450] There are two types of progress marks 16F: black square marks and white square marks. As shown in FIG. 36, immediately after the start of the reception operation, there is one black square mark, but as the reception operation progresses, the number of black square marks increases, and finally there are five black square marks lined up. As the number of black square marks increases, the same number of white square marks disappear. Instead of multiple progress marks 16F, the degree of progress may be displayed by changing the size or color of a single shape, or may be expressed using animation.

[0451] Instead of the receiving operation display screen 16MM, a plurality of light-emitting elements (LEDs) may be provided, as in the left heating power display unit 17L of the first embodiment, and the progress of the receiving operation may be displayed in multiple stages by the light emitted by the LEDs. For example, at the beginning of the receiving operation, only one LED may be lit, and as the receiving operation progresses, the number of lit LEDs may increase. Alternatively, the progress may be expressed by flashing the LEDs or by changing the color of the light. This may allow the user to be informed of the completion of the receiving operation in an intuitive and easy-to-understand manner.

[0452] Next, the operation of the limiting unit 55 shown in FIG. 36 will be described. As shown in FIG. 36, during the operation of receiving cooking condition data via the communication unit 51, the input operation unit 15 on the cooking appliance 1 side cannot interrupt the receiving operation midway. For example, even if the input keys 152M and 153M are pressed, the operation of the data acquisition unit 53 cannot be interrupted.

[0453] The cooking condition data stored in the cooking condition data storage unit 42 of the cooking appliance 1 is displayed in the form of a first specific screen 16M1 as shown in FIG.

[0454] In Figure 37, 173 is an external recipe identification unit, as explained in the first embodiment. This makes it easy to see that the collaborative cooking menu currently displayed on the first specific screen 16M1 has been obtained from an external source.

[0455] As shown in FIG. 37, a specific collaborative cooking menu (in this case, "Ratatouille") is displayed on the first specific screen 16M1, and cooking operation can be started immediately by touching the input key 151M.

[0456] Furthermore, by operating input key 156M or 157M, it is possible to select either heating by the right heating section (right heating port 4R) or heating by the left heating section.

[0457] Furthermore, by operating the input key 152M, cooking using a specific linked cooking menu (in this case, "Ratatouille") obtained from an external source can be canceled. Once a cancellation operation is performed, the display returns to the standby initial screen 16MH, and in this state, it is necessary to touch the input key 153M again. In this way, once the cooking condition data corresponding to one cooking menu previously obtained is canceled, cooking condition data for another cooking menu can be obtained again (it is also possible to obtain cooking condition data for the same cooking method again).

[0458] Furthermore, if a specific linked cooking menu (in this case, "Ratatouille") obtained from an external device has not yet been cooked (including when the user forcibly cancels the cooking process midway), it cannot be changed to another linked cooking menu (for example, "Hamburger"). To change the menu, you must operate input key 152M to return to the initial standby screen 16MH.

[0459] In FIG. 37, the light-emitting parts 21M of the input keys 156M and 157M are lit, and after selecting either the left heating unit specification part 171L or the right heating unit specification part 171R with the input keys 156M and 157M, the user can manually set the control conditions such as heat power using the input keys 156M and 157M.

[0460] The following Figure 38 shows that when cooking in the collaborative cooking mode KM3 based on cooking condition data obtained from outside, the microwave heating output level can be adjusted when proceeding to cooking process 2.

[0461] As shown in (B) of the following Figure 38, the microwave heating output level is displayed in a total of five levels, from "strong" to "weak," in the second area 23. The user can select such microwave output level by operating input keys 156M and 157M. Therefore, in the final step (cooking step 2), the user can adjust the heating intensity of the microwaves depending on the finished state of the food to be cooked.

[0462] FIG. 39 is an explanatory diagram showing the relationship between the cooking steps of the cooperative cooking menu and the operations of the input operation unit. In the example of FIG. 39, the cooperative cooking menu is made up of three cooking steps: cooking step 1, cooking step 2, and cooking step 3.

[0463] 39, the cooking condition data is specified in a predetermined computer program format to wait for input of input key 151M to start the heating operation, and to stop the heating operation when input of input key 153R (153L) is made, or to stop the heating operation when a certain condition (continuous cooking time or reaching of target temperature) is met. Control conditions such as heat power may also be specified.

[0464] The program included in the cooking condition data defines heating pause periods P3 and P5, which will be described later, but does not define the duration of these heating pause periods P3 and P5. However, to prevent cooking from being interrupted for an excessively long time, it is possible to include a process that counts the elapsed time for each of cooking steps 1 and 2, for example, based on the end of each step, and issues an alarm and forcibly stops the execution of the cooking menu when, for example, 30 minutes have elapsed.

[0465] In the example of cooking condition data in Figure 39, cooking process 1 is performed using a microwave heating source (second heating means) HM2, cooking process 2 is performed using the same microwave heating source, and finally cooking process 3 is provided in which the food to be cooked is moved onto top plate 3 and finishing induction heating is performed to compensate for insufficient heating.

[0466] In addition, in this cooking device 1, a measure is added to prevent the setting of cooking modes, control conditions, etc. from being inadvertently changed in response to an external command signal.

[0467] In the "second collaborative cooking menu" in the example of Figure 39, the second heating means HM2 is operated first, and after that heating operation is completed, the induction heating source is operated as the first heating means HM1, but the radiant heat heating means 12 may also be operated as the third heating means simultaneously with the second heating means HM2.

[0468] As shown in FIG. 39, the "second collaborative cooking menu" shown here consists of four steps. P1 is the first stage (preparation period), which is the period from when input key 153M is operated to execute the cooperative cooking menu until the cooking operation is started by input key 151M.

[0469] When the input key 153M is operated, if the "permission condition" as described above is satisfied, the control device 40 displays the first specific screen 16M1. Note that the first specific screen 16M1 is not shown in Fig. 39.

[0470] When the first specific screen 16M1 is displayed, one of the linked cooking menus can be selected by operating input keys 154M and 155M. After that, by operating input key 151M, the mode switches to linked cooking mode and proceeds to the heating cooking step P2.

[0471] When the first specific screen 16M1 is displayed, if the identification information 167 of the user's desired collaborative cooking menu is displayed in a predetermined position on the first specific screen 16M1 (default display), there is no need to operate the input keys 154M and 155M.

[0472] P2 is a period of cooking by the second heating means HM2 (microwave heating source) (cooking step 1). This cooking process 1 is started when the control device 40 confirms that the door 7 has been opened once during the preparation period P1 and then closed. The door open / close signal from the open / close detection unit 10 described in the first embodiment is used.

[0473] The cooking step 1 basically ends automatically when the heating time predetermined by the operation program of the linked cooking menu has elapsed or when the temperature of the food to be cooked reaches a set value (e.g., 90°C). For example, in one linked cooking menu, heating begins with a microwave output of 500 W. Furthermore, if the user opens the door 7 at any time, microwave irradiation is instantly stopped and the heating operation is stopped.

[0474] In the example of FIG. 39, the input key 152M of the central operation unit 15M is pressed to end cooking process 1.

[0475] At the stage when cooking step 1 is started, the control device 40 has already finished determining whether the permission conditions are met, and therefore knows which heating section of the first heating means HM1 (induction heating means) is in use. In other words, it knows the usage status of both the right heating port 4R and the left heating port 4L. Therefore, as a default setting, the control device 40 determines to use the "right heating section" 4R in cooking step 3 of the cooperative cooking mode, and occupies this right heating port 4R.

[0476] P3 is a heating pause period during which cooking step 1 by the second heating means HM2 (microwave heating means) is temporarily stopped and cooking step 2 by the second heating means HM2 is started again.

[0477] This pause period P3 is a period required to check the degree of heating of the food in cooking step 1, add seasonings, or add another food to be cooked and carry out cooking step 2. For example, in cooking step 1, only frozen food can be heated, and in cooking step 2, seasonings can be added or another food (such as non-frozen food) that heats up faster than frozen food can be added. This broadens the range of cooking options. The heating pause step P3 ends when the input key 152M is pressed, and the process proceeds to the cooking step 2 of P4.

[0478] P4 is a cooking period (cooking step 2) using the second heating means HM2 (microwave heating means). In this cooking step, the user can individually set control conditions (for example, cooking time and target temperature) by operating at least one of the four input keys 156M to 159M. Then, when input key 151M is pressed to command the cooking to be stopped, cooking step 2 ends and the process proceeds to a heating pause period P5.

[0479] During this heating pause period P5, the user opens the door 7, removes the food to be cooked from inside the heating chamber 6, and places it on the top plate 3. The food to be cooked is placed inside a heated object such as a metal pot. Then, when the input key 153R for the right heating port 4R is pressed to command the start of cooking, the heating pause step P5 ends and the process proceeds to the heating cooking period P6 (the "cooking step 3" of induction heating).

[0480] This heating pause period P5 is the period required to check the degree of heating of the food in cooking step 2, add seasonings, or add another food to be cooked and then carry out cooking step 3. For example, in cooking step 2, only frozen food can be heated as the food to be cooked, and in cooking step 3, the food can be immersed in seasonings or cooking liquid, or a food that has been preheated separately can be added to the same food to be heated. This broadens the range of cooking options.

[0481] P6 switches from cooking step 2 using the second heating means HM2 (microwave heating source) to cooking step 3 using the first heating means HM1 (in this case, induction heating means, for example, the right heating port 4R). In this cooking step 3, when cooking using the right heating port 4R as described above, the user can individually set control conditions (for example, cooking time and target temperature) by operating input keys 154R and 155R (see Figure 8).

[0482] Furthermore, if cooking step 3 is performed using left heating port 4L, the user can individually set control conditions (for example, cooking time and target temperature) by operating input keys 154L and 155L.

[0483] Then, when input key 153R is pressed to command stopping cooking, cooking step 3 ends and operation in the linked cooking mode ends. In the case of timer cooking, induction heating cooking ends automatically when the time has elapsed, and cooking step 3 ends.

[0484] 39, the right operation unit 15R of the right heating port 4R becomes unusable from the point at which the user decides to start cooking using the input key 151M, not when the cooperative cooking menu is selected, i.e., when the identification information 167 indicating the name of the cooking on the cooperative cooking menu is displayed on the central display unit 16M. Note that if the left heating port 4L is set as the default setting, the left heating port 4L will be occupied.

[0485] As is clear from the above description, the control device 40 performs the following function restriction process. (1) The input signal from the right operation unit 15R is invalidated. As a result, the right heating port 4R cannot be used in any mode other than the combined cooking mode during the cooking period (cooking step 1) to cooking period (cooking step 3). (2) Even when the heating cooking period (cooking step 1) begins, the left operating unit 15L can be used (the input signal from the left operating unit 15L is not invalidated).

[0486] In this way, when the heating cooking period (cooking step 1) begins, the control device 40 moves from the cooking step 1 stage to a state in which only the right heating port 4R for cooking step 3 is occupied.

[0487] Therefore, the right heating port 4R is "occupied" by the selection of the linked cooking menu. Also, when viewed from the perspective of the first heating means HM1 as a whole, the use of only a portion (the right side) of the three heating sections is "restricted."

[0488] Even after the heating cooking period (cooking step 1) ends, the restricted state of the right heating port 4R is not released. In addition, during the cooking process 1, the first specific screen 16M1 is displayed, and the user can easily understand that the cooperative cooking mode has been entered, so the execution of other cooking menus is not restricted for the first heating means HM1 and the second heating means HM2. This also applies to the heating pause period P3 to cooking process 2.

[0489] Furthermore, even if the control device 40 detects that the door 7 has changed from an open state to a closed state before the start of the heating cooking period (cooking process 1), if the temperature inside the heating chamber 6 is higher than the reference value, there is a concern that the control device 40, the non-contact (infrared) sensor 13, and thermistor sensor 14 may mistakenly recognize the abnormally high temperature in the heating chamber 6 as indicating that cooking has been completed even before cooking has started. Therefore, if the temperature in the heating chamber 6 is too high before the start of the heating cooking period (cooking process 1) and before the start of cooking process 2, the first specific screen 15M1 displays the message that "the second heating means HM2 (microwave heating means) cannot be used immediately due to high temperature."

[0490] The periods indicated by thick arrows in Figure 39 are the reception restriction period for one cooking condition data (recipe data) and the "addition restriction period" for additional cooking condition data (recipe data). These reception restriction periods and "addition restriction periods" are hereinafter collectively referred to as "restriction periods."

[0491] As shown in FIG. 39, the "starting point" of the "restricted period" is the point in time when a cooperative cooking menu (for example, "Ratatouille") is selected with a specific input key 154M or 155M.

[0492] The "starting point" of the "limited period" may be the time when the display of the first specific screen 16M1 begins. In other words, as shown by the large dashed arrow in Figure 45, the "starting point" may be changed to the time when the collaborative cooking mode KM3 is selected with the input key 153M. In this case, the "limited period" extends up to an earlier point P1A in the first stage (preparation period) P1.

[0493] When the input key 151M is touched once and the first specific screen 16M1 is displayed, the limiting operation by the limiting unit 55 is carried out as follows.

[0494] That is, the restriction unit 55 built into the control device 40 effectively prohibits changing a specific coordinated cooking menu A obtained from outside to another coordinated cooking menu B (for example, "hamburger steak") during the "restriction period," as shown in Figure 39. To change the menu, it is necessary to operate the input key 152M to temporarily cancel the coordinated cooking mode KM3 and return to the initial standby screen 16MH.

[0495] In other words, once the "restricted period" indicated by the thick arrow in Fig. 39 has begun, you can cancel cooking using the specific linked cooking menu A obtained from an external device at any time by operating the input key 152M. Once you perform the cancellation operation in this way, the display returns to the initial standby screen 16MH, and you must touch the input key 153M again in that state.

[0496] Furthermore, after the input key 153M is touched for a specific linked cooking menu A obtained from outside, the control device 40 cannot obtain cooking condition data (recipe data) for another linked cooking menu C.

[0497] In other words, once the "restricted period" indicated by the thick arrow in Figure 39 begins, by operating input key 152M, cooking can be started using the cooking condition data (recipe data) of the specific linked cooking menu A that has been acquired thereafter, but further cooking condition data (recipe data) cannot be acquired from outside until all cooking steps of this cooking menu A have been completed.

[0498] As is clear from the above description, the cooking device 1 of the second embodiment has the following configuration. a first heating means HM1 including a first heating section (right heating section) 4R and a second heating section (left heating section) 4L; a second heating means HM2 capable of heating the food to be cooked in a heating chamber 6 located away from the first heating means HM1; a control device 40 that controls the second heating means HM2 and the first heating means HM1; a display unit 16M that displays control information of the second heating means HM2 and the first heating means HM1, The control device 40 has a number of cooperative cooking menus for cooking one food item using the second heating means HM2 and the first heating means HM1, the number of which is equal to the number of types of food items; The control device 40 is configured to perform the following operations when it receives a command to display an integrated cooking menu via the input key 153M. (1) The relationship between the second heating means HM2 and the first heating means HM1 and the "permission condition" of "not having been used before" and "the temperature of the heating chamber 6 is low" is determined. Then, it is determined whether the cooperative cooking menu can be executed.

[0499] (2) If it is determined that the collaborative cooking menu can be executed, the first specific screen 16M1 is displayed on the central display section 16M.

[0500] (3) At least one of the cooperative cooking menus is displayed selectably on the first specific screen 16M1 by enabling the input functions of the corresponding input keys 154M and 155M.

[0501] (4) When one linked cooking menu is selected, a command to start the linked cooking mode from input key 151M is awaited.

[0502] (5) When a command to start the combined cooking mode is received, microwaves from the second heating means HM2 are supplied to the heating chamber 6, and cooking step 1 is started.

[0503] (6) When cooking step 1 is completed automatically or by user command, the heating pause period P3 is entered, and a command to resume the linked cooking mode (for cooking step 2) from input key 151M is awaited.

[0504] (7) When a command to start the linked cooking mode is received from the input key 151M, microwaves are supplied from the second heating means HM2 to the heating chamber 6, and cooking step 2 is started.

[0505] After that, the heating pause period P5 is passed, and the heating cooking period P6 (cooking step 3) begins. In this cooking step 3, by operating input keys 154R and 155R, it is possible to set the control conditions for induction heating using right heating port 4R.

[0506] As described above, in this embodiment 2, when the predetermined permission conditions are met, the first specific screen 16M1 for the coordinated cooking mode is displayed, and this display screen makes it possible to easily proceed with the transition to the coordinated cooking mode using the relevant right heating port 4R or left heating port 4L and second heating means HM2. Furthermore, if the permission conditions are not met, the first specific screen 16M1 itself is not displayed, so there is no risk of misuse or misunderstanding by the user. In other words, a highly convenient combined cooking device can be realized without impairing user operability.

[0507] Furthermore, there is a heating pause period P3 between cooking step 1 and cooking step 2, and the length of this heating pause period P3 is determined by the timing at which the user issues a cooking restart command using input key 151M. That is, in this embodiment 1, the time required to check the degree of heating of the food in cooking step 1, add seasonings, or add another food and perform cooking step 2 can be secured. This makes it easy to use and allows the user to expand their cooking repertoire.

[0508] Furthermore, because of the restriction unit 55, once the input key 153M is touched for one specific coordinated cooking menu A, the control device 40 will not acquire cooking condition data (recipe data) for another coordinated cooking menu C. This prevents the inadvertent reception of another cooking menu (including the control menu for the combined cooking mode or the control menu for the single cooking mode) during coordinated cooking. This eliminates concerns about user confusion or operational interference with the cooker 1 due to reception.

[0509] 40 to 49 show the display contents of the terminal-side display screen (which also serves as an input operation screen) 216 of the communication terminal device 200, and will be explained in order below. Note that the "terminal-side display screen" 216 will be referred to as the "display screen" 216 hereinafter.

[0510] 39(A) and 39(B) are enlarged views of the display screen 216 of the communication terminal device 200. FIG. The display screen 216 is formed by covering the surface of a liquid crystal display screen or an organic EL display screen with a glass plate. Although they do not appear as physical structures on the upper surface (surface) of the glass plate, various icons (input keys) 488, 489, 491L, 491M, 491R, 492 to 496, etc., which will be described later, can be visually recognized by displaying them on the display screen 216. Although specific parts of the glass plate itself do not emit light or generate images, in the following explanation, the expression "displayed on the display screen" will be used from the perspective of a user viewing the display of characters, figures, and other information.

[0511] The "icons" allow desired input. That is, each icon has a capacitance sensing key. By touching the icon, the touch operation unit 215 (see FIG. 31) generates a command signal to the central processing unit 212.

[0512] To indicate the presence and function of an icon, a specific function is displayed in text or graphics (at least when it is in a state where it can accept input). For example, as in the example of Figure 40(A), text information such as "Left IH operation unit" is displayed at the position of icon 491L.

[0513] Reference numeral 481 denotes a menu display section on the initial screen shown in Fig. 40(A). This menu display section 481 changes to a menu selection display section 482 for the left heating section in Fig. 40(B). Also, in Fig. 41(A), it changes to a heating source selection display section 483 that says "Select heating source."

[0514] Furthermore, menu display section 481 changes to range grill control menu selection display section 484, which displays "RG control menu selection" in FIG. 42(B). Furthermore, the menu display section 481 changes to a cooperative cooking menu display section 485, which displays "Select cooperative cooking menu" in FIG. 47(A).

[0515] In Figure 48(B), menu display section 481 changes to a preparation information display section 486 titled "Next Preparation Guide." In Figures 48(A) and (B), menu display section 481 changes to a coordinated cooking menu name display section 487 showing "fried chicken," one of the coordinated cooking menus.

[0516] Returning to Fig. 40(A), reference numeral 490 denotes a warning information display section as an initial standby screen. Before operation starts, the heating chamber 6 may already be hot due to heat from the previous cooking, and Fig. 40(A) shows an example of a warning about this. It also indicates that the power is already on.

[0517] 40, 491M is a selection section (icon) of central operation section 15M. By operating central operation section 15M, cooking can be performed using heating sections other than left and right heating ports 4L and 4R, as described in the first embodiment.

[0518] 40, 491L is a selection section (icon) of the left operation section 15L, and 491R is a selection section (icon) of the right operation section 15R. An advice display selection section (icon) 492 is provided. When this is touched, the audio notification section 50 notifies, in the central display section 16M, reference information for the operation corresponding to the touched situation.

[0519] In FIG. 40, FG indicates the user's fingertip. In FIGS. 40(A) and (B) and other figures, triangular marks (icons) 501 and 502 are screen switching marks.

[0520] The next Figure 41(B) also has a screen switching mark 503. When these marks are touched, the display screen 216 can be switched in a specific order with each touch. Incidentally, when the screen switching mark 502 is touched in Figure 40(B), the display screen 216 moves to the right, and the next display screen 480 appears from the left side.

[0521] In addition, the screen switching marks 501 to 503 may be omitted by providing a scroll function in which the fingertip FG is moved while touching the display screen 216, and the display screen is moved accordingly.

[0522] In FIG. 40(A), when the left operation section selection section (icon) 491L is touched, the screen switches to the display screen 216 shown in FIG. 40(B) without touching the screen switching marks 501 to 504.

[0523] In FIG. 40(B), 493 is a control menu display section (icon) for the IH only cooking mode. There are a total of seven control menus for the IH only cooking mode. Four of them are displayed in the right half of the display screen 216 in Figure 40(B). These control menu display areas (icons) 493 are "Boil water," "Boil," "Cook rice," and "Boil water + Keep warm."

[0524] The remaining three control menus are displayed on the left half of display screen 216: a "keep warm" control menu display section (icon) 488, a "frying" control menu display section (icon) 494, and a "preheating" control menu display section (icon) 489.

[0525] In FIG. 40(B), 495 is a menu screen display section (icon) for selecting to return to the initial menu display screen. 496 is a confirmation display section (icon) that is displayed when one of the control menus (for example, "boil water") in Fig. 40(B) is selected. When this is pressed, for example, in the case of the aforementioned "boil water", the screen automatically switches to the control condition setting screen for boil water.

[0526] Next, FIG. 41(A) will be described. 497A and 497B are induction heating source selection units (icons) for selecting the left IH coil 9L or the right IH coil 9R. 497C is a heating source selection unit (icon) for selecting the microwave heating source (second heating means HM2).

[0527] In FIG. 41(A), 498 is a range grill heat source selection section (icon), and 499 is a combined cooking mode selection section (icon). In FIG. 41(A), when the range grill heat source selection section (icon) 498 is touched, the display screen changes to the display screen 216 in FIG. 41(B).

[0528] In Fig. 41(A), 497A is an induction heating source selection section (icon) for selecting the left IH coil 9L, and 497B is a selection section (icon) for the right IH coil 9R.

[0529] 497C is a selection section (icon) for selecting the microwave induction heating source 189. When the screen switching mark (icon) 503 is touched in FIG. 41(B), the display screen 216 in FIG. 41(B) changes to that in FIG. 42(B).

[0530] Next, FIG. 42(B) will be described. Reference numeral 500 denotes an RG control menu selection section (icon) that shows the RG control menu. The RG control menu has a total of 10 options, such as "warming," "manual microwave," and "meat defrosting."

[0531] Figures 42(A) and (B) show the state in which all (10) of the Range Grill (RG) control menus are displayed. Figure 42(A) shows five control menus 500, and Figure 42(B) shows the remaining five control menus 500.

[0532] 42(A) and 42(B) indicate the rear and front when the display screen 216 is held horizontally. The display screen 216 can be operated without any problems whether it is held horizontally, vertically, or at an angle.

[0533] Next, Figures 43(A) and (B) will be described. FIG. 43(A) shows a state in which the "warm" control menu 500 is selected from the range grill (RG) control menu in the state of FIG. 42(A).

[0534] When the fingertip FG touches the RG control menu selection section (icon) 500, the selection section 500 senses the touch and changes the display color, for example, the characters are inverted to white. When the input confirmation key display section (icon) 496 is touched in this state of Fig. 43(A), the display screen changes to the display screen 216 of Fig. 43(B).

[0535] Figure 43(B) is the default screen for the Range Grill (RG) control menu. Reference numeral 504 denotes a name display section (icon) of the RG control menu. The control menu display form and design in Fig. 43(B) are similar to those shown in Fig. 15 of embodiment 1. Such a display is possible because of the presence of cooking appliance database 217 and remote operation information generation unit 219 (see Fig. 31).

[0536] In Fig. 43(B), 505 is a temperature display section (icon) of the RG control menu. In the example of Fig. 43(B), the default value is 80°C, but the next selectable values ​​are 75°C and 85°C, so these are also displayed at the same time.

[0537] As shown in FIG. 43(B), the next display candidates "Oven" and "Parboil Leafy Vegetables" are displayed adjacent to the name display section (icon) 504 of the RG control menu in slightly smaller size.

[0538] If the user wishes to change the microwave's set temperature to 75°C in the state shown in Figure 43(B), the user simply places his / her fingertip FG on the 75°C display. Similarly, if you want to change "Warm" in the control menu to "Oven" or "Pre-boil leafy vegetables," you can do the same by touching the candidate change marks (icons) 519 and 520 near "Oven" or "Pre-boil leafy vegetables."

[0539] 43(B), reference numeral 506 denotes a reference image display section. The reference image may be something other than a photograph, and may be an illustration showing an image of "warming" in the control menu.

[0540] Next, Figures 44(A) and (B) will be described. When the orientation of communication terminal device 200 is changed to the vertical direction, display screen 216 changes to a portrait orientation as shown in Figures 44(A) and (B). Note that display screen 216 may be set to be fixed in a portrait orientation as shown in Figures 44(A) and (B).

[0541] Switching between FIG. 44(A) and FIG. 44(B) can be done simply by touching the screen switching mark (icon) 503. Next, Figures 45(A) and (B) will be described. When the fingertip FG touches the control menu selection section 500 to select the "warm" control menu 500 shown in Figure 45(A), the display color changes, for example, the characters are inverted to white, as shown in Figure 45(A). When the input confirmation key display section (icon) 496 is touched in this state of Figure 45(A), the display screen changes to the display screen 216 shown in Figure 45(B).

[0542] Next, in the state shown in Fig. 45(B), if you want to change the (upper heating limit) temperature setting of the "warm" range (microwave heating) to 75°C, you can simply place your fingertip FG on the 75°C display area (temperature display area 505 of the RG control menu). Then, the display screen 216 will change to the state shown in Fig. 46(A).

[0543] In Fig. 45(B), 507A is an auxiliary information display section, which is displayed near the reference image display section 506. In Fig. 45(B), the user is advised to select a set temperature.

[0544] Next, FIG. 46(A) will be described. As shown in Figure 46(A), the display shows that the set temperature has been changed to 75°C. However, because the control conditions have not yet been finalized, the other set temperature of "85°C" remains displayed.

[0545] In the state shown in FIG. 46(A), the remote control signal transmission key display section (icon) 521 is displayed for the first time. In this Figure 46(A), when the transmission key display section 521 is selected, the setting information (cooking condition data) for the control menu "Warm" of the "Microwave only cooking mode KM1" displayed in this Figure 46(A) is transmitted in bulk to the heating cooker 1 as remote control information.

[0546] The state in Figure 46 (A) is the stage where all conditions for executing ``Warm'' in the RG control menu have been selected, so the heating temperature condition of ``75°C'' displayed on the temperature display unit 505 is sent to the heating cooker 1.

[0547] In Fig. 46(A), 507B is an auxiliary information display section, which is displayed near the reference image display section 506. Fig. 46(A) shows that pressing the send key display section 521 completes the input operation.

[0548] At the stage shown in Figure 46(B) after the transmission of the remote operation command (signal) (including cooking condition data) has been completed, the stop key display (icon) 522 for stopping the heating operation by remote operation is displayed for the first time. Pressing this stops the heating operation at the stage shown in Figure 46(B). Pressing this stop key display 522 once returns to the first stage, requiring the user to re-enter all remote operation conditions.

[0549] The communication terminal device 200 is provided with a stop key display unit (icon) 522 that can immediately transmit command information to command the heating to stop, thereby providing a function for ensuring the safety of the cooking appliance 1.

[0550] Various input operations have been explained in sequence in Figures 40 to 46(A), but up to the stage of Figures 40 to 46, the communication terminal device 200 and the first server 321 or the cooking appliance 1 are not in a state where they can communicate wirelessly.

[0551] For example, even if the communication terminal device 200 is not connected to the cooking appliance 1, the communication terminal device 200 can perform the displays and inputs shown in Fig. 40 to Fig. 46 by itself. Therefore, as shown in Fig. 46(A), it is sufficient to connect to the cooking appliance 1 before pressing the send key display unit 521 to send. Therefore, even if the communication terminal device 200 performs the input operations shown in Fig. 40 to Fig. 46(A), it does not hinder the operation of acquiring and sending information from outside via the communication unit 51 of the cooking appliance 1.

[0552] Next, FIG. 47(A) will be described. Figure 47(A) shows the display screen 216 that is displayed when the selection section 499 for the combined cooking mode KM3 shown in Figure 41(A) is touched. Note that the display screen 216 in Figure 45(A) may also be displayed by touching the central operation section selection section 491M in Figure 40(A). However, when the central operation section selection section 491M is touched, the selection screen is also used for the range grill cooking mode (combined cooking mode KM2), so there are a few more touch operations required to select the combined cooking mode KM3.

[0553] FIG. 47(A) shows an example in which "fried chicken" is selected as one of the cooking menus in the cooperative cooking mode KM3. When the user wants to cook "fried chicken" and touches the linked cooking menu display section (selection section) 500C, the display color changes, for example, to white characters, as shown in FIG. 47(A).

[0554] When the input key display section (icon) 496 is touched in the state of Fig. 47(A), the display screen 216 (not shown) for cooking "fried chicken" is displayed. The display screen 216 of Fig. 47(A) is a display screen showing the selection stage of "fried chicken".

[0555] Note that Figure 47(A) only shows the collaborative cooking menu and omits the subsequent diagram for selecting the heating unit and control conditions, but if you select (touch) the collaborative cooking menu selection section (icon) 500C on the display screen 216 of Figure 47(A), you will proceed to the display screen 216 for setting the selected cooking menu (for example, ``fried chicken'').

[0556] Between Figures 47 and 48, there is actually a setting display screen 216 for "fried chicken." This display screen 216 may display an icon (not shown) for selecting the left or right heating unit (IH coils 9L, 9R), as shown in embodiment 1 (Figure 16). Alternatively, the left or right heating unit may not be specified, and the heating ports 4L, 4R may be selected on the cooking appliance 1 side that receives the cooking condition data. Also, as shown in Figure 46, a send key display section (icon) 521 is displayed on this setting display screen 216. This allows the cooking condition data for "fried chicken" to be sent.

[0557] Figure 47 (B) is an example of a notification corresponding to "Reference Information 1" FA1 that is automatically notified by the heating cooker 1 when the heating control unit 43 detects the progress of the cooking process in the middle of cooking process 1 when cooking "fried chicken" using the cooking menu in the collaborative cooking mode KM3.

[0558] In this embodiment 2, the "Reference Information 1" FA1 notified by the cooking appliance 1 notifies two things: to open the door 7 of the heating chamber 6, and then to remove the heated ingredients from the heating chamber 6, as shown in Figure 47 (B).

[0559] The display screen 216 of the communication terminal 200 also displays, as shown in Figure 47 (B), a preparation work reference image 509 indicating that the door 7 should be opened and a preparation work reference image 510 indicating that the food to be cooked should be removed together with the tray, as content corresponding to the above-mentioned reference information 1FA1. Note that 511 is attention-calling information, and 512 is supplementary information that explains the user's work.

[0560] Next, FIG. 48(A) will be described. The display screen 216 in FIG. 48(A) displays the first cooking step of "fried chicken." 513 is a process information display section. In Fig. 48(A), it is displayed that microwave heating is still continuing. 514 is a display section for the next cooking process information. In the example of this figure, it is displayed that induction heating will be performed next at the left heating port 4L.

[0561] A recommended menu display section 515 may include a recommended cooking menu (another cooking) searched for from inventory information SD1 previously acquired from refrigerator 800 (not shown).

[0562] The example in Figure 48(A) suggests that there is another recommended menu item that can be cooked in heating chamber 6, which is currently being used for "fried chicken," after that heating chamber is no longer in use. Note that cooking appliance 1 has a function that enables it to acquire refrigerator inventory information (inventory data) SD1 via wireless communication with refrigerator 800 (not shown).

[0563] At the stage of Fig. 48(A), the recommended menu is not automatically displayed in detail. If the user touches the detailed display instruction section (icon) 523 that is displayed for the first time at this stage, detailed information is displayed as shown in Fig. 48(B).

[0564] It should be noted that a selection section equivalent to the detailed display instruction section (icon) 523 as shown in Fig. 48(B) is not displayed in central display section 16M of cooking appliance 1. After a certain period of time, the screen of Fig. 48(B) automatically returns to display screen 216 of Fig. 48(A).

[0565] At this stage in FIG. 48(A), the stop key display section (icon) 522 is also displayed for stopping the heating operation by remote control.

[0566] In FIG. 48(B), 487 is a name display section of the cooperative cooking menu, and in this case, the name of the food to be cooked, "fried chicken," is displayed. Reference numeral 516 denotes a display section for a recommended menu. Specific contents of the recommended menu are displayed in the display section for recommended menu 515. It is recommended to defrost and heat the food.

[0567] In FIG. 48(B), 517 is auxiliary information for the recommended menu, and indicates that cooking can be done using the "warm" control menu that uses microwave heating. 518 is a cooking reference image of the recommended menu. It can be an illustration (image) instead of a photograph. At this stage in FIG. 48(B), the stop key display section (icon) 522 is also displayed for stopping the heating operation by remote control.

[0568] Next, FIG. 49(A) will be described. Display screen 216 in FIG. 49(A) shows a state in which cooking step 1 of "fried chicken" has ended and the cooking has entered a heating pause period, that is, a transition period TR, before moving on to cooking step 2.

[0569] The transition period TR does not end unless the user who is actually cooking in front of the cooking appliance 1 presses the input key 151M of the cooking appliance 1. In other words, the length of the transition period is user dependent.

[0570] Therefore, the communication terminal device 200 does not have a function to remotely (by wireless communication) command the transition period TR and restart the cooking process from a remote location, regardless of the operation performed. This is to improve the safety of the cooking appliance 1.

[0571] Reference numeral 513 denotes a process information display section. In Fig. 49(A), this indicates that microwave heating has finished. Reference numeral 514 denotes a display section for the next cooking process information. In the example shown in this figure, it indicates that induction heating will be performed next at the right heating port 4R.

[0572] A recommended menu display section 515 is provided. If there is a recommended cooking menu (another cooking) searched for from inventory information SD1 previously obtained from refrigerator 800 (not shown), this display section 515 will show that there is a recommended cooking menu, as shown in Fig. 49(A).

[0573] When the detailed display instruction section (icon) 523 displayed on the display screen 216 in Figure 49(A) is touched, details of candidate cooking menus that can be performed in parallel with cooking process 2 in the heating chamber 6 are displayed, as shown in Figure 49(B).

[0574] A selection section equivalent to the detailed display instruction section (icon) 523 as shown in Fig. 49(A) may also be displayed on the central display section 16M of the cooking appliance 1. However, if the display screen of the central display section 16M is not of the touch input type, it is necessary to display that an appropriate input key should be pressed.

[0575] When the input confirmation key display section (icon) 496 in Figure 49(B) is pressed, information on a recommended cooking menu (another cooking) that uses the heating chamber 6 is transmitted to the cooking appliance 1. In other words, the user who is cooking in front of the cooking appliance 1 is informed of their intention to "agree with the recommended menu."

[0576] When information about a recommended cooking menu (another cooking) is transmitted to the cooking appliance 1, the owner of the communication terminal device 200 may not be in the kitchen 601 (not shown) when receiving the notification of the recommended cooking menu (another cooking). In other words, it is conceivable that another user may be in front of the cooking appliance 1 at that moment. In any case, the user can know that cooking can be performed simultaneously by effectively using the heating chamber 6.

[0577] In the above description, the communication terminal device 200 such as a smartphone performs wireless communication 400 by Bluetooth (registered trademark) with the cooking appliance 1. As another method, since the cooking appliance 1 has an NFC input / output unit 221 (see FIG. 31) for short-range wireless communication, the communication terminal device 200 may be brought into direct proximity with or into contact with an NFC input / output unit (not shown) on the cooking appliance 1 side for input.

[0578] Summary of embodiment 2. As is clear from the above description, in this second embodiment, the cooking device 1 according to the first disclosure is disclosed in the following form. a first heating means HM1 for heating an object to be heated at a first location (above the top plate 3); a second heating means HM2 for heating the food to be cooked in a second location (heating chamber 6) separate from the first location; an input operation unit 15 for receiving instructions from a user; A communication unit 51 that receives cooking condition data 2 (CD2, CD4, CD5, CD6) from an external device; a control device 40 that controls the first heating means HM1, the second heating means HM2, and the communication unit 51, The control device 40 includes a heating control unit 43 that executes a cooperative cooking mode KM3 in which the first heating means HM1 and the second heating means HM2 are driven with a time lag based on cooking condition data 1, a data acquisition unit 53 that acquires the cooking condition data 2 via the communication unit 51 in order to execute heating cooking in the cooperative cooking mode for a specific food, and a restriction unit 55 that restricts the acquisition of the cooking condition data 2 by the data acquisition unit 53 via the communication unit 51 during a preparation period P1 before starting cooking in the cooperative cooking mode KM3 (i.e., the preparation period P1 before "cooking step 1" shown in FIG. 37). The restriction unit 55 is configured to restrict the acquisition of new cooking condition data from the communication unit 51 until the cooking process of the cooking menu to which the acquired cooking condition data 2 is applied is completed.

[0579] This prevents another cooking menu (including the control menu for the combined cooking mode or the control menu for the single cooking mode) from being accidentally received during coordinated cooking, and allows the cooking menu of the cooking condition data 2 to be stably executed. Furthermore, it is possible to prevent the operation of the control device 40 from being affected or to prevent the user from being confused or misled by the cooking condition data for another cooking menu that may be inadvertently received during the cooking process.

[0580] In this second embodiment, the cooking system according to the fourth disclosure is disclosed in the following form. That is, A cooking system comprising a cooking device 1 having a plurality of heating means HM1, HM2, HM3 with different heating capacities or heating principles, and having a function of a linked cooking mode KM3 in which food is heated sequentially by the heating means at least in two locations, and a communication terminal 200 for communicating with the cooking device 1, The cooking device 1 has cooking condition data 1 for executing the cooking operation of the combined cooking mode KM3, The communication terminal device 200 includes a cooking appliance database 217 that generates cooking condition data 2 for executing the cooking operation of the cooperative cooking mode KM3, and a cooking condition data transmission unit 231 that transmits the cooking condition data 2 to the cooking appliance 1, The cooking appliance 1 includes a storage unit 42 that stores the cooking condition data 1 and the cooking condition data 2 received from the communication terminal 200 in association with identification information 167, a heating control unit 43 that reads out the cooking condition data 1 or the cooking condition data 2 from the storage unit 42 in response to a user's selection operation of the cooperative cooking mode KM3 or the selection operation of the identification information 167 and uses the data for cooking in the cooperative cooking mode KM3, and a restriction unit 55 that restricts acquisition of the cooking condition data 2 from an external source during a standby period before starting cooking in the cooperative cooking mode KM3. The restriction unit 55 is configured to restrict the acquisition of new cooking condition data 2 until the cooking process of one cooking menu to which the acquired cooking condition data 2 is applied is completed.

[0581] This makes it possible to prevent another cooking menu (including the control menu for the combined cooking mode and the control menu for the single cooking mode) from being accidentally received during cooperative cooking. Therefore, the cooking menu of the received cooking condition data 2 can be effectively used in the cooker 1 to perform cooking.

[0582] Furthermore, it is possible to prevent the operation of the control device 40 from being affected or to prevent the user from being confused or misled by the cooking condition data for another cooking menu that may be accidentally received during the cooking process, thereby improving the usability of the cooking appliance 1.

[0583] Furthermore, in this second embodiment, the cooking system according to the fifth disclosure is disclosed in the following form. That is, A cooking device 1 including a first heating means HM1 that heats an object to be heated with a heating section (heating ports 4L, 4R) set on a top plate 3, and a second heating means HM2 that heats and cooks an object to be cooked in a heating chamber 6 located at a different location from the heating section; A cooking system including a communication terminal 200 that communicates with the cooking appliance 1, The cooking device 1 has a cooking menu (for example, a linked cooking menu) corresponding to a specific food to be cooked, The cooking device 1 has a function of storing cooking condition data for executing the cooking menu, The communication terminal device 200 has a function of providing the cooking condition data CD5 to the cooking appliance 1 and a function of acquiring cooking execution data CD9 of the cooking menu from the cooking appliance 1, The cooking device (1) includes a limiting unit (55) that determines the timing of receiving the cooking condition data from the communication terminal (200), The present invention discloses a heating and cooking system configured such that the restriction unit 55 permits the acquisition of the cooking condition data CD5 after a specific cooking menu is selected, and restricts the acquisition of new cooking condition data CD5 until the cooking process related to the acquired cooking condition data CD5 is completed.

[0584] This prevents another cooking menu (including a control menu for the composite cooking mode) from being inadvertently received before or after the start of the cooking process, and allows the cooking menu of the received cooking condition data CD5 to be executed. Furthermore, it is possible to prevent the operation of the control device 40 from being affected or to prevent the user from being confused or misled by the cooking condition data for another cooking menu that may be inadvertently received during the cooking process.

[0585] Furthermore, the communication terminal 200 can acquire the cooking execution data CD9 for the cooking menu, so that the cooking status of the cooker 1 can be checked even if the user is in a remote location. That is, according to the cooking system of the fifth disclosure, the status of the cooker 1 can be monitored on the communication terminal device 200 side, improving convenience.

[0586] Embodiment 3 Figures 50 to 52 show a cooking device according to embodiment 3. Figure 50 is an explanatory diagram 1 showing the display operation of the central display unit immediately after the cooking device 1 is started up. Figure 51 is an explanatory diagram 2 showing the display operation of the central display unit after the cooking device 1 is started up. Figure 52 is an explanatory diagram 3 showing the display operation of the central display unit after the cooking device 1 is started up. Note that parts that are the same as or equivalent to the configurations of embodiments 1 and 2 described in Figures 1 to 49 are given the same reference numerals.

[0587] In this third embodiment, the configuration of the cooking device 1 shown in the second embodiment is modified, and the contents displayed on the central display unit and the procedure for selecting the cooking mode are partially modified.

[0588] Referring to Figure 50, when the main power switch 20 is in the "OFF" position, the central display unit 16M is not activated and therefore does not display any information. When the main power switch 20 is turned "ON", the control device 40 performs a self-diagnosis to check for abnormalities, etc., and then displays the display screen 1A (standby initial screen 16MH) of FIG.

[0589] On the display screen 16MH in Figure 50, 60A is a display message informing users that the power is on. 60B is two-dimensional information (two-dimensional code) for guiding users to a dedicated recipe posting site (cloud server 300) via a wide area network such as the Internet. 60C is text (two-dimensional information explanation text) explaining the meaning of the two-dimensional code.

[0590] When the communication terminal 200 is started and the two-dimensional code 60B is optically read, it can be connected to an external recipe information providing server 301 (not shown) that stores information on various cooking recipes. As explained in the first embodiment, the recipe information providing server 301 is provided with a recipe DB (database) 302 (not shown) that stores data on various cooking recipes (cooking condition data).

[0591] After display screen 1A is displayed, display screen B is automatically displayed. Note that, as shown in Fig. 51, after display screen B is displayed, display screens B1 to B3 may be displayed for a certain time (for example, for 3 seconds or 5 seconds) at regular time intervals (for example, 3 seconds or 5 seconds each). Then, display screen B is displayed again.

[0592] On the other hand, the audio notification unit 50 may, when the display screen B shown in FIG. 50 is displayed or when the display screens B1 to B3 are displayed as shown in FIG. 51, notify the user of the display contents (displayed information) of the display screen by audio and guide the user which input keys to operate.

[0593] For example, at the time of display screen B1, it would be good to display a message such as "When using both the heating chamber and IH for coordinated cooking, please select key number 1." In this case, "key number 1" refers to input key 153M. "key number 2" refers to input keys 154M and 155M.

[0594] It is preferable to display the number "1" on the top surface of the central operation unit 15M by printing or engraving it on the operation surface of the input key 153M. Alternatively, the operation surface of the input key 153M itself may be illuminated so that the number can be easily identified by the user. A similar configuration can be adopted for the other keys, numbered 2 and 3.

[0595] As shown in display screen B1 in Fig. 51, when the "key numbered 1," i.e., the input key 153M, is displayed as a specific input key on the initial standby screen 16MH, the input function of the input key 153M is enabled. In other words, during the initial standby period TP, the input keys shown on display screens B1 to B3 are displayed with their input functions enabled.

[0596] After the above process, when the input key 153M is pressed for the first time, the central display unit 16M switches from display screen B to the first specific screen 16M1 as shown in Fig. 52. However, as explained in the embodiment, if "permission condition 1" and "permission condition 2" are not met, a display or audio notification will be made to the effect that the collaborative cooking mode KM3 cannot be selected, and the display will return to screen A.

[0597] The control device 40 is configured to automatically open the main power switch 20 and cut off the main power supply when the time that has passed without any of the input keys 153MC, 154M, 155M being operated exceeds a certain time limit (30 minutes) from the time when the standby initial screen 16MH (display screen A) is displayed or the content of display screen B is audibly notified by the audio notification unit 50.

[0598] As shown in FIG. 52, during an acquisition-disabled period TZ after startup, the cooking appliance 1 cannot acquire any data from the communication terminal device 200 (acquisition is restricted by the restriction unit 55).

[0599] On the other hand, since the acquisition period TB begins from the time when the input key 153M is pressed, if the cooking appliance 1 is connected to the communication terminal device 200, the cooking condition data can be acquired.

[0600] As shown in FIGS. 50 to 52, display areas 525, 526, and 527 for the names of cooking modes are displayed in central display area 16M. Display section 525 displays corresponding to the cooperative cooking mode KM3, display section 526 displays corresponding to the combined cooking mode KM2, and display section 527 displays corresponding to the induction heating source 9 single cooking mode KM1.

[0601] As shown in FIG. 50, the display screen B shows a list of display sections 525 to 527, and displays guide messages (text information) 530, 531, and 532 that identify the input key to be operated first, in one-to-one correspondence with each of the display sections.

[0602] Therefore, the user can check information common to the first heating means HM1, the second heating means HM2 and the third heating means HM3, such as warning information (standby common information 60N), on the standby initial screen 16MH (display screen A).

[0603] Furthermore, since the guide messages 530, 531, 532 can be viewed on guide screen B (16MA), the user will not be confused about how to operate the cooker before cooking begins, and a cooker 1 with high operability and convenience can be realized.

[0604] As can be seen from the above explanation, explanations 533, 534, 535 indicating the contents of each cooking mode are displayed simultaneously with the displays on display sections 525-527.

[0605] Furthermore, at the timing when the display screen B is displayed on the guidance screen 16MA, the audio notification unit 50 notifies the user by voice which input keys to operate.

[0606] Therefore, the user can obtain information about the input keys to be operated not only visually but also by voice, which is expected to further improve operability.

[0607] In this embodiment 3, the control device 40 also includes a heating control unit 43, a data acquisition unit 53 that acquires the cooking condition data 2 via the communication unit 51 in order to perform heating cooking in the collaborative cooking mode for a specific food to be cooked, and a restriction unit 55 that restricts the data acquisition unit 53 from acquiring the cooking condition data 2 via the communication unit 51 during the waiting period before starting cooking in the collaborative cooking mode KM3 (before "cooking process 1").

[0608] Furthermore, the limiting unit 55 does not limit acquisition of cooking condition data 2 after the input key 153M is operated, that is, during the acquisition permitted period TB shown in FIG.

[0609] Furthermore, the restriction unit 55 has a function of restricting the acquisition of new cooking condition data B from the communication unit 51 until the cooking process of the cooking menu to which the once acquired cooking condition data 2 is applied is completed.

[0610] This prevents another cooking menu (including the control menu for the combined cooking mode or the control menu for the single cooking mode) from being accidentally received during coordinated cooking, and allows the cooking menu of the cooking condition data 2 to be stably executed. Furthermore, it is possible to prevent the operation of the control device 40 from being affected or to prevent the user from being confused or misled by the cooking condition data for another cooking menu that may be inadvertently received during the cooking process.

[0611] Summary of embodiment 3. As described above, the third embodiment discloses the cooking device 1 having the following configuration. That is, a first heating means HM1 (induction heating source 9) for heating an object to be heated at a first location (above the top plate 3); A second heating means HM2 that heats the food to be cooked in a second location (heating chamber 6) that is separated from the first location and isolated from the first location; an input operation unit 15 for receiving instructions from a user; a communication unit (51) for receiving cooking condition data (2) from an external device; A display unit 16 that displays cooking information; a control device (40) that controls the first heating means, the second heating means, the communication unit (51), and the display unit (16), After starting up the display unit 16, the control device 40 displays a standby initial screen 16MH on the display unit 16, The standby initial screen 16MH displays at least one of reference information 1 (standby common information 60N) common to the first heating means HM1 and the second heating means HM2, and reference information 2 (explanations 525-527, 533-535) showing the contents of a plurality of heating cooking modes (KM1-KM3) or the operation of the input operation unit 15 to select the heating cooking mode, When a specific input, i.e., operation of the input key 153M, is made on the input operation unit 15 during the display period of the standby initial screen 16MH, the control device 40 acquires the cooking condition data 2 via the communication unit 51.

[0612] With this configuration, the coordinated cooking operation based on cooking condition data 1 held by the heating cooker 1 and the coordinated cooking operation based on cooking condition data 2 acquired from outside do not interfere with each other, which is expected to prevent confusion for the user and improve usability.

[0613] Furthermore, in the third embodiment, the input operation unit 15 has input keys 153L, 153M, and 153R that correspond to the plurality of cooking modes KM1 to KM3, respectively, and that select the cooking modes individually, The initial standby screen 16MH was configured to display information (explanatory statements 525-527, 533-535 in Fig. 50) relating to the selection of the first heating means and the second heating means for selecting the input keys 153L, 153M, 153R as the reference information 2. In other words, the guide screen 16MA shown in Fig. 50 was temporarily and automatically displayed.

[0614] This configuration is expected to prevent confusion for the user when selecting one of a plurality of cooking modes, and to improve usability.

[0615] Furthermore, in the third embodiment, the input operation unit 15 has input keys 153L, 153M, and 153R corresponding to the plurality of cooking modes KM1 to KM3, respectively, for selecting the cooking modes individually, The standby initial screen 16MH displays information common to the first heating means HM1 and the second heating means HM3 for selecting the input keys 153L, 153M, and 153R as the reference information 1 (60N), After the reference information 1 is displayed, the restriction unit 55 of the control device 40 restricts the acquisition of the cooking condition data 2 via the communication unit 51 until the specific input key (153M) is operated.

[0616] With this configuration, the coordinated cooking operation based on cooking condition data 1 stored on the heating cooker 1 side and the coordinated cooking operation based on cooking condition data 2 acquired from outside do not interfere with each other, which does not cause confusion for the user, and also makes it easy to select the heating cooking mode, which is expected to improve usability.

[0617] Furthermore, the restriction unit 55 is configured to restrict the acquisition of new cooking condition data B from the communication unit 51 until the cooking process of the cooking menu to which the once acquired cooking condition data 2 is applied is completed.

[0618] This prevents another cooking menu (including the control menu for the combined cooking mode or the control menu for the single cooking mode) from being accidentally received during coordinated cooking, and allows the cooking menu of the cooking condition data 2 to be stably executed.

[0619] Embodiment 4 Figure 53 shows a cooking device according to embodiment 4, and explains the operational steps of the control device 40 of the cooking device 1 from when the cooking device 1 is started until just before cooking begins. Figure 54 is a flowchart 1 for explaining the control operation of the cooking device of Figure 53. Figure 55 is a flowchart 2 for explaining the control operation of the cooking device of Figure 53. Note that parts that are the same as or equivalent to the configurations of the embodiments explained in Figures 1 to 52 are given the same reference numerals.

[0620] In this fourth embodiment, the configuration of the control device 40 of the cooking appliance 1 shown in the first embodiment is modified. In FIG. 53, steps SU1 to SU4 are the same as those explained in FIG. 27, so a duplicate explanation will be omitted.

[0621] After the stage where the standby initial screen 16MH is displayed on the central display unit 16M (step SU1), in step SU1A, an automatic connection operation with an external device (the communication terminal device 200 or the cloud server 300) is performed, and if the communication connection is successful, the process proceeds to step SU1B.

[0622] In step SU1B, it is determined whether or not the input key 153M of the input operation unit 15 has been operated, and if it has been operated, the process proceeds to the next step SU2.

[0623] When it is confirmed at step SU2 that recipe information (cooking condition data) has been acquired from the outside, an "input prohibition period" TC begins at step SU2.

[0624] When the "input prohibition period" TC begins, the input functions of the various input keys in the input operation unit 15 are disabled by the control device 40. For example, the input function of the input key 153M is disabled by the control device 40, so the collaborative cooking mode KM3 cannot be selected. However, as an exception, the operation button (input key) 20A of the main power switch 20 remains enabled, so it is possible to shut off the power at any time.

[0625] During the "input prohibition period" TC, the control device 40 compares the latest state of each component of the cooking appliance 1 and determines whether the state satisfies the permission conditions 1 and 2.

[0626] If it is determined that permission conditions 1 and 2 are simultaneously satisfied (SU6), the identification information included in the recipe information (cooking condition data) acquired from the external device (the internet terminal 200 or the cloud server 300) is displayed on the central display unit 16M. In this case, the identification information (for example, "Name: Hamburger") is displayed on the first specific screen 16M1 (step SU7).

[0627] 53, the "cooking condition changeable period" TB3 begins when the identification information (e.g., "Name: Hamburger") is displayed in the first specific screen 16M1. This cooking condition changeable period TB3 ends when the input key 151M for starting cooking is pressed.

[0628] When the "cooking condition changeable period" TB3 begins, the input functions of the various input keys that were disabled during the "input prohibited period" TC are released by the control device 40.

[0629] Therefore, during the "cooking condition changeable period" TB3, the user can use input keys 154M, 155M, etc. to adjust the control conditions (heat value, heat level, target temperature, heating time, etc.) for the cooking menu that the acquired cooking condition data applies to (for example, "hamburger steak"). However, there are some control conditions that cannot be changed depending on the cooking menu.

[0630] On the other hand, a case where, at the stage of step SU3, the control device 40 compares the latest state of the cooking appliance 1 and determines that the state does not satisfy the permission conditions 1 and 2 (step SU4) will be described.

[0631] The content of the standby initial screen 16HM in the central display unit 16M is partially changed to display in text a message that the recipe information (cooking condition data) acquired from the external device cannot be executed with the current cooking appliance 1. The same message is also audibly announced by the audio notification unit 50 (step SU5A).

[0632] Furthermore, in step SU5A, the communication unit 51 transmits a message to the communication terminal 200 or cloud server 300 that has transmitted the recipe information (cooking condition data) that the recipe information (cooking condition data) is currently unavailable. Then, the source of the recipe information (cooking condition data) is notified so that the status of the cooking appliance 1 can be known.

[0633] 53, from step SU1B to immediately before step SU2, the restriction unit 55 does not restrict the external acquisition of cooking condition data 2. The restriction unit 55 permits the external acquisition of cooking condition data 2 under "certain conditions."

[0634] The "certain conditions" means that, for example, if one-time cooking condition data 2 is acquired from outside, cooking condition data 2 cannot be acquired thereafter (until the cooking process based on the previously acquired cooking condition data 2 is completed).

[0635] During the input prohibition period TC (shown in FIG. 53) after step SU2, the restriction unit 55 prohibits the user from changing the control conditions, such as the heat level and heating temperature, for the cooking condition data 2 that has been acquired, using the input operation unit 15. To achieve this prohibition effect, before the determination result that the permission conditions are met is made (step SU7), the first specific screen 16M1 is not displayed, and neither the identification information of the cooking menu nor the control conditions are displayed.

[0636] During the input prohibition period TC, even if cooking condition data 2 is transmitted from the communication terminal device 200 or the cloud server 300, the cooking condition data received by the communication unit 51 (hereinafter referred to as "unauthorized recipe data") is only stored in a temporary storage area inside the cooking appliance 1, and is controlled by the control device 40 so as not to be stored in a predetermined area (not stored in the storage unit 42). The temporary storage area is automatically erased when the cooking process is completed and the main power switch 20 is turned off.

[0637] Even if unauthorized recipe data is acquired during the input prohibition period TC, this unauthorized recipe data will not be used as a basis for executing a cooking menu during the next "cooking condition changeable period" TB3. Therefore, the user cannot arbitrarily change the heat level and other control data included in the unauthorized recipe data and use it for cooking.

[0638] When the input prohibition period TC ends and the next "cooking condition changeable period" TB3 begins, cooking conditions (control conditions) such as heat level can be changed using the input operation unit 15. However, even in this case, new cooking condition data 2 cannot be obtained from the communication unit 51 until the cooking process of one collaborative cooking menu scheduled for cooking at this stage is completed. If you want to obtain different cooking condition data 3 and execute another cooking menu, you must temporarily cancel the collaborative cooking mode KM3 using the input key 152M.

[0639] Furthermore, after the start of the "cooking condition changeable period" TB3, the "non-permitted recipe data" transmitted from outside cannot be used in place of the cooking menu to be started.

[0640] This prevents another cooking menu (including the control menu for the combined cooking mode or the control menu for the single cooking mode) from being accidentally received during coordinated cooking, and allows the cooking menu of the cooking condition data 2 to be stably executed. Furthermore, it is possible to prevent the operation of the control device 40 from being affected or to prevent the user from being confused or misled by the cooking condition data for another cooking menu that may be inadvertently received during the cooking process.

[0641] Next, we will explain Figure 54. A basic operation program from turning on the main power to starting cooking preparation is stored in a memory device 41 inside the control device 40. The cooking appliance 1 in FIG. 54 is a built-in type, and therefore the power plug (not shown) is always connected to a commercial (AC) power source from the time the kitchen furniture 600 is installed. Therefore, the user presses the operation button 20A of the main power switch 20 to turn on the power (step SW1 in FIG. 54).

[0642] Then, as explained in the first embodiment, a predetermined low power supply voltage is supplied to the control device 40 via the DC power supply conversion unit (not shown) of the power supply circuit 67, and the control device 40 is started up. The control device 40 starts its own diagnosis of whether there is an abnormality by its own control program (SW2).

[0643] The respective related circuits of the first heating means HM1, the second heating means HM2, and the third heating means HM3 check for the presence or absence of abnormalities. The data of these check results is collected centrally by the control device 40, which determines the presence or absence of abnormalities.

[0644] In step SW2, it is stated that "startup information is transmitted to the outside," which means that an operation information signal that notifies the start of operation of the cooking appliance 1 is transmitted from the communication unit 51 to a "home control device" (not shown) called an "integrated information management device" or an "integrated power control device" (HEMS controller) or the like that is located in a living space such as the kitchen 601 (not shown). Alternatively, the operation information signal may be transmitted to the cloud server 300 by connecting to the networks 203, 204, 205 via an access point such as a wireless router 340 (not shown).

[0645] Also, in step SW2, it says "obtain information (such as a power consumption regulation command) from outside," which means obtaining command signals and information from the home control device (not shown), communication terminal device 200, cloud server 300, etc. via communication unit 51.

[0646] In step SW2, the communication unit 51 accesses the home control device and acquires information useful for health management, such as cooking menus and recipe information, within the range previously set by the user. For example, information that the user of the cooking appliance 1 previously sent to the cloud server 300 via the Internet using the communication terminal device 200 or the like can also be acquired immediately after starting up the control device 40. When any information is acquired, the information may be displayed on the common screen (initial standby screen) 16MH.

[0647] If no abnormality is found in the cooking appliance 1, the control device 40 activates the display unit 16. Then, it displays a message that "There is no abnormality, so cooking can begin" (SW3). The display screen at this initial stage is the common screen 16MH described in FIG. 25 etc. in the first embodiment. Therefore, common standby information 60N such as information indicating that the power is on is displayed. At the same time as these displays, the audio notification unit 50 notifies the same information by audio.

[0648] Next, after the abnormality determination is completed as described above, the control device 40 issues a notification and voice guidance to prompt the user to select a heating means using the display unit 16 and the voice notification unit 50 (SW4), and then proceeds to the next step SW5.

[0649] In step SW5, it is determined whether or not the door 7 of the heating chamber 6 is open. If the door 7 remains closed, the process proceeds to step SW7.

[0650] Step SW7 judges whether or not the input key 153L or 153R has been operated as the third selection means for selecting the "single cooking mode" KM1 using the first heating means (induction heating means) HM1.

[0651] To select the "single cooking mode" of the first heating means HM1, the user must operate either the input key 153L of the left operation unit 15L or the input key 153R of the right operation unit 15R.

[0652] Therefore, in this step SW7, if either one of the input keys 153L or 153R is operated, the result is determined to be "Yes" and the process proceeds to the next step SW8. If neither the input key 153L nor 153R is operated, the process returns to step SW4.

[0653] In step SW8, the display of the common screen 16MH is stopped, and instead the third specific screen 16M3 is displayed. The third specific screen 16M3 is the same as that shown in FIG.

[0654] If it is determined in step SW5 that the door 7 of the heating chamber 6 is open, the process proceeds to step SW6. Step SW6 is a process for starting the reception of the cooperative cooking mode KM3 and the combined cooking mode KM2.

[0655] At the moment of proceeding to step SW6, the communication unit 51 transmits a specific signal indicating that the cooking appliance 1 can acquire cooking condition data from an external device and can operate in response to a remote control signal to the "home control device" (not shown) and the cloud server 300. The specific signal is transmitted to the cloud server 300 as a type of the operation information data OS.

[0656] The "remote operation command (information)" here has the same meaning as the "remote operation command (information)" RS explained in the second embodiment. The "remote operation command" in this embodiment 4 includes commands regarding input operations corresponding to all cooking modes of the heating cooker 1, including the cooperative cooking mode KM3 and the composite cooking mode KM2, display command signals for the central display unit 16M in the cooperative cooking mode, composite cooking mode, etc., and further display commands regarding the right heating power display unit 16R and the left heating power display unit 16L.

[0657] After step SW6 in FIG. 54, when the acquisition period begins, the reception of cooking condition data (recipe data) for the cooperative cooking mode KM3 and the reception of cooking condition data for the combined cooking mode are not restricted by the restricting unit 55 as long as the permission conditions are met and only one reception is allowed.

[0658] The "remote operation command" RS in this fourth embodiment includes commands to change control conditions such as heating power and heating time. However, with regard to heating power (heating capacity), it does not include a command to increase the heating power (to increase the heating capacity), but is a signal that only decreases the heating power.

[0659] Furthermore, in all cooking modes including the cooperative cooking mode KM3, no information that serves as a command to start a heating operation is included, and therefore the cooking appliance 1 does not receive a command to start a heating operation from this remote operation command RS.

[0660] In step SW9, it is determined whether the input key 153MC has been operated as the first selection means for selecting the cooperative cooking mode KM3. Then, reception of cooking condition data (recipe data) for the cooperative cooking mode KM3 is permitted, and the cooking condition data is received from the outside via the communication unit 51. In this case, the "permission conditions" are determined as described in the first embodiment, and if the conditions are met, the cooking condition data is stored in the cooking condition data storage unit 42.

[0661] If the input key 153M is operated, the answer is determined to be "Yes" and the process proceeds to the next step SW10. In step SW10, the display of the common screen 16MH is stopped, and the first specific screen 16M1 is displayed instead.

[0662] On the other hand, if the input key 153M is not operated, the process proceeds to the next step SW11. In step SW11, it is determined whether or not the input key 154M or 155M, which serves as the second selection means for selecting the combined cooking mode KM2, has been operated.

[0663] When the input key 154M or 155M is operated, reception of cooking condition data (recipe data) for the combined cooking mode KM2 is permitted, and cooking condition data is received from the outside via the communication unit 51. The cooking condition data is then stored in the cooking condition data storage unit 42. Then, the process proceeds to the next step SW12.

[0664] In step SW11, it is also determined whether specific permission condition 3 is met in combined cooking mode KM2. For example, if heat from the most recent high-temperature cooking remains and the temperature in heating chamber 6 is high (for example, 90°C or higher), the control menu that automatically controls microwave cooking at the temperature detected by the temperature sensor ("Warm" described in FIG. 13) cannot be executed, and the determination result is "No."

[0665] In step SW12, the display of the common screen 16MH is stopped, and the second specific screen 16M2 is displayed instead. If neither of the input keys 154M nor 155M is operated in step SW11, the process returns to the previous step SW9.

[0666] As can be seen from Figure 54, the period from the next step (step SW6) after door 6 is opened to step SW10 or step SW12 is the "acquisition period", during which cooking condition data can be acquired and operation upon receiving the remote control command RS becomes possible.

[0667] Next, we will explain Figure 55. FIG. 55 shows a continuation of the operation steps of FIG. In step SW10, the first specific screen 16M1 is displayed, and a voice prompt is given to make an input via the input operation unit 15 to perform the cooperative cooking mode KM3.

[0668] In the next step SW13, it is determined whether input key 151M has been operated. If the determination here is "Yes," the process proceeds to the next step SW14, where a cooking process is started using the heat source corresponding to the collaborative cooking menu. Note that the cooking process here may be either cooking process 1 and cooking process 2, or cooking process 3 and beyond.

[0669] In step SW15, it is determined whether or not all cooking processes (including preheating processes and extension processes) have been completed. If the cooking processes have been completed, the process proceeds to step SW22.

[0670] Step SW22 is almost the same as step SW4. However, since it is immediately after one cooking session, there is a high possibility that the heating chamber 6 and top plate 3 are at high temperatures. Therefore, in step SW22, information regarding the presence of a high temperature area is displayed on the common screen (initial standby screen) 16MH.

[0671] On the other hand, in step SW12, the second specific screen 16M2 is displayed, and a voice guide is given to prompt the user to input via the input operation unit 15 in order to perform the combined cooking mode KM2.

[0672] In the next step SW16, it is determined whether input key 151M has been operated. If the determination here is "Yes," the process proceeds to the next step SW17, where the cooking process is started using the heat source corresponding to the composite cooking menu. Note that the cooking process here may be either cooking process 1 and cooking process 2, or cooking process 3 or more.

[0673] In step SW18, it is determined whether or not all cooking processes (including preheating processes and extension processes) have been completed. If the cooking processes have been completed, the process proceeds to step SW22 described above.

[0674] Next, steps SW8 and after will be described. In step SW8, the third specific screen 16M3 is displayed, and a voice guide is given to prompt the user to input via the input operation unit 15 in order to perform the single cooking mode KM1.

[0675] Then, in the next step SW19, it is determined whether the input key 153R on the right operation unit 15R of the right heating port 4R has been operated. Alternatively, it is determined whether the input key 153L of the left heating port 4L has been operated. If the determination here is "Yes," it proceeds to the next step SW20, where the cooking process for the single cooking menu using the first heating means HM1 is started. Note that the cooking process here refers to cooking process 1 (including the preheating process).

[0676] In step SW21, it is determined whether or not all cooking processes (including preheating processes and extension processes) have been completed. If the cooking processes have been completed, the process proceeds to step SW22 described above.

[0677] As can be seen from Figure 55, the period from steps SW10 to SW15, the period from steps SW12 to SW18, and the period from steps SW8 to SW21 are all "remote control non-compatible periods." In other words, these "remote control non-compatible periods" continue until the end of the cooking process (steps SW15, SW18, SW21). In other words, the control device 40 performs an operation to prohibit remote control from outside.

[0678] At the stages of steps SW15, SW18, and SW21, the control device 40 cancels the "remote operation incompatible" processing. Therefore, if a new cooking operation (for example, an induction heating only cooking mode) is started after step SW15 or SW18, the maximum power consumption value may be suppressed (peak cut command) by an external remote operation command RS during the cooking process.

[0679] In the above explanation, the "remote control non-compatible" period is until all cooking steps in the cooperative cooking mode KM3, the combined cooking mode KM2, and the single cooking mode KM1 are completed (steps SW15, SW18, SW21). However, this may be changed. For example, when cooking step 1 (including the preheating step) is performed using the right heating port 4R, if the target of the external remote operation command RS is specified to the right heating port 4R, the "remote operation not supported" processing may be canceled at the end of cooking step 1. The same applies to...
