Description

[Technical Field]

[0001] The present disclosure relates to a cooking device capable of accepting setting input of heating conditions from an external communication device, and a cooking system capable of transmitting an operation signal from the cooking device to an external device based on operation information transmitted from the external communication device to the cooking device. [Background technology]

[0002] Conventionally, there has been known a cooking system that includes a communication light-projecting unit disposed below a top plate and that emits an optical signal upward through the top plate, and that transmits operation signals, such as driving or stopping a ventilation fan or turning on or off a light, from the communication light-projecting unit of the cooking appliance to an external device, for example, a range hood (see, for example, Patent Document 1).

[0003] There is also known an induction cooking appliance that includes a heating operation operating means and an operating means for a ventilation device, which is an external device, and that operates the ventilation device in conjunction with the state when the heating operation operating means turns the heating means on or off, or transmits a wireless signal to the ventilation device to wirelessly turn the ventilation device on or off so that the ventilation device can be operated manually by the ventilation device operating means (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2003-114028 A (page 4, Figure 1) [Patent Document 2] JP 2010-027326 A (Page 5, Figure 2) Summary of the Invention [Problem to be solved by the invention]

[0005] In the cooking system disclosed in Patent Document 1 and the induction cooking appliance disclosed in Patent Document 2, in order to operate or stop the ventilation means or device, which is an external device, setting information for operating or stopping is input from the operating means of the cooking appliance, and a signal for operating or stopping is sent from the cooking appliance to the ventilation means or device.

[0006] In addition, in order to turn the lights on or off, setting information for turning the lights on or off is input from the operating means of the cooking appliance, and a signal for turning the lights on or off is sent from the cooking appliance to the ventilation means and device.

[0007] Therefore, in order to operate or stop the ventilation means or device, or to turn on or off the lights, the user must stand in front of the cooking appliance to operate or stop the ventilation means or device, or to turn on or off the lights.

[0008] Therefore, even if a user wants to operate or stop the ventilation means or device, or turn the lights on or off while doing other things a little distance away, they cannot operate it from the spot, so they have to go to the front of the cooking appliance, which may be inconvenient for the user.

[0009] The heating cooker according to Disclosure 1 and the heating cooking system according to Disclosure 2 of the present disclosure are intended to solve the above-mentioned problems, and aim to provide a heating cooker and a heating cooking system that do not impair convenience for the user, by allowing inputs to operate or stop ventilation means or devices, or to turn lights on or off, to be made from an external device equipped with communication means, rather than from the operating means of the heating cooker, so that even if the user is located far away from the heating cooker, they can do so without having to move to the front of the heating cooker. [Means for solving the problem]

[0010] The heating cooker according to disclosure 1 of the present disclosure comprises a heating means for heating an object to be heated provided within the main body, a power operation unit for switching the power supply of the main body from ON to OFF or from OFF to ON, an input operation unit for setting the main body and the heating of the heating means, a transmitting device for transmitting an operation signal for driving the first external device, including starting or stopping the driving of the first external device, or setting the driving conditions, and a communication unit for receiving operation information for driving the first external device from the input operation unit or receiving operation information for driving the first external device from the input means of the second external device, and when the communication unit receives operation information for driving the first external device from the input operation unit or the input means of the second external device, the transmitting device transmits an operation signal for driving the first external device corresponding to the operation information for driving the first external device to the first external device.

[0011] The cooking system according to disclosure 2 of the present disclosure comprises a cooking appliance including a heating means for heating an object to be heated provided within the main body, a power supply operation unit for switching the power supply of the main body from ON to OFF or from OFF to ON, an input operation unit for setting the main body and the heating of the heating means, a display unit for displaying the heating status of the heating means, a transmitting device for transmitting an operation signal for driving the first external device, including starting or stopping the first external device, or setting the driving conditions, and a communication unit for receiving operation information for driving the first external device from the input operation unit, a first external device including a ventilation fan for ventilating the air in the room and a light for illuminating the cooking appliance from above, and a second external device having an input unit for inputting information for setting the operation of the cooking appliance and operation information for driving the first external device, including starting or stopping the first external device, or setting the driving conditions, and capable of transmitting the information input from the input unit to the communication unit. [Effects of the Invention]

[0012] According to Disclosure 1 of the present disclosure, when the communication unit receives operation information regarding the operation of the first external device from the input operation unit or the input means of the second external device, an operation signal regarding the operation of the first external device corresponding to the operation information regarding the operation of the first external device is transmitted from the transmitting device to the first external device. Therefore, the user can operate the first external device not only by input operation from the cooking appliance main body, but also by input operation from a short distance away using a second external device such as a smartphone, thereby improving user convenience and providing an easy-to-use cooking appliance.

[0013] Furthermore, according to disclosure 2 of the present disclosure, a cooking appliance is provided with a transmitting device that transmits an operation signal regarding the operation of the first external device, including either starting or stopping the operation of the first external device, or setting the operation conditions, and a communication unit that receives operation information regarding the operation of the first external device from an input operation unit; a first external device that includes a ventilation fan that ventilates the air in the room and a light that illuminates the cooking appliance from above; and a second external device that has an input unit that inputs information regarding the operation of the cooking appliance and operation information regarding the operation of the first external device, including either starting or stopping the operation of the first external device, or setting the operation conditions, and that can transmit the information input from the input unit to the communication unit.Therefore, input operations such as starting the ventilation fan of the first external device or turning on the light can be performed from the second external device, such as a smartphone, and therefore a cooking appliance that is more convenient for the user and easier to use can be provided.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, embodiments of a cooking device and a cooking system according to the present disclosure will be described with reference to the drawings. Note that the present disclosure is not limited to the embodiments described below. Furthermore, in the following drawings, including FIG. 1, the dimensional relationships between components may differ from the actual ones. Furthermore, in the following description, terms indicating directions are used as appropriate to facilitate understanding, but these terms are for explanatory purposes and do not limit the present disclosure. Examples of terms indicating directions include "up," "down," "right," "left," "front," and "rear." Note that the cooking device includes a composite cooking device having multiple types of heating means.

[0016] Embodiment 1 In the present embodiment 1, the "first heating means" HM1 is a heat source for heating an object to be heated that is placed on the top plate 3, which will be described later. A typical example of the first heating means HM1 is an induction heating coil. A typical induction heating coil (IH coil) is one that is made by bundling about 30 thin copper or aluminum wires of about 0.1 mm to 0.3 mm, twisting a plurality of these bundles, and winding them into a spiral shape.

[0017] There are also induction heating coils made up of 1,000 to 1,500 windings of about 0.05 mm thick. There are also proposals for induction heating coils made of a ring-shaped conductor made of a flat conductive material. All of these configurations correspond to the "IH coil" that is the main part of induction heating source 9.

[0018] In the present embodiment 1, the "second heating means" HM2 refers to a heat source for heating an object to be heated housed inside the heating chamber 6, which will be described later. The second heating means HM2 may be a steam generator that supplies high-temperature steam, such as superheated steam, i.e., a boiler. In the present embodiment 1, 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. Furthermore, the cooking appliance 1 may be provided with a plurality of heat sources.

[0019] In the present embodiment 1, 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. Furthermore, in the present embodiment 1, a heat source using a radiant electric heat source, such as a sheath heater, mica heater, carbon heater, ceramic heater, infrared heater, or radiant heater, is used, but heat sources that generate heat in other forms or methods may also be used. The third heating means HM3 refers to a means that can heat and cook food in one heating chamber 6.

[0020] It is also possible to use a combination of multiple heat sources with different heating principles, such as a heat source composed of an electric heater and a gas combustor (burner). Also, an induction heating source 9 may be used as the heat source for heating the heating chamber 6. The heat source may also be a steam generator, i.e., a boiler, that supplies high-temperature steam, such as superheated steam.

[0021] Furthermore, the third heating means HM3 may be a heat source that heats the wall surface of the heating chamber 6 from the outside, or may be a heat source that is installed in the internal space of the heating chamber 6 and heats the atmosphere in the internal space. Alternatively, a heat-generating member that becomes hot by induction heating may be installed in the heating chamber 6, and the wall surface of the heating chamber 6 may be heated from the outside by this heat-generating member, or the air inside the heating chamber 6 may be heated.

[0022] (System Configuration) 1 is a schematic diagram showing a cooking system 1a according to the first embodiment of the present disclosure. The cooking system 1a includes a cooking appliance 1, a wireless router 400, and a second external device 200 which is an external communication device such as a smartphone having a function of wirelessly communicating with the cooking appliance 1 via a cloud server 300 which serves as an external communication device for the wireless router 400 and the cooking appliance 1.

[0023] The device control unit 100 included in the second external device 200 manages communications and information from the cloud server 300, and performs data conversion for notifying the cloud server 300 of voice input from the user. The second external device 200 also includes an audio input unit (not shown) for inputting the user's voice and an audio output unit (not shown) for outputting the voice. The second external device 200 is, for example, an information processing terminal. The information processing terminal may be a tablet terminal with a communication function, a smart speaker, or the like, in addition to a smartphone.

[0024] The second external device 200 and the recipe information providing server 301 in the cloud server 300 are connected via a network 202 using a telecommunications line such as the Internet. Here, the recipe information providing server 301 includes a recipe providing site. The recipe providing site includes a recipe database 302.

[0025] Furthermore, the recipe information providing server 301 and the cooking appliance 1 are connected to a network 203 such as an internet line via a wireless router 400 installed in the home. The wireless router 400 is a device that serves as an interface between the network 203 and a communication unit 51 of the cooking appliance 1, which will be described later, and is a repeater that connects the second external device 200 and the recipe information providing server 301 to the communication unit 51 so that they can communicate with each other.

[0026] The recipe information providing server 301 also contains heating setting data for the cooking appliance 1, and records heating conditions and the like that can be set from a second external device 200 (described later) to the cooking appliance 1. The settable heating conditions include data such as the heating menu and setting condition list in Fig. 13 (described later).

[0027] In the cooking system 1a, condition data CD3 such as cooking conditions corresponding to a recipe created by a user in the second external device 200 can be transmitted to the recipe information providing server 301. Then, the recipe information providing server 301 can temporarily store the condition data CD3 such as cooking conditions in the recipe database 302 and provide it to the cooker 1. In other words, when the second external device 200 is located at a place far away from the house where the cooker 1 is installed, such as an outside location, the condition data CD3 such as cooking conditions of the second external device 200 can be saved in the recipe information providing server 301. This provides high convenience.

[0028] Furthermore, the condition data CD3 such as cooking conditions includes not only data corresponding to the recipe but also operation instruction data of operation information for the first external device 60. The first external device 60 includes, for example, a ventilation fan 61, such as a range hood, that ventilates the air in the room, and a light 62 that illuminates from above a top plate 3 (described later) that covers the top surface of the cooking appliance 1. Hereinafter, the first external device 60 may be referred to as a range hood 60.

[0029] The cooking appliance 1 downloads cooking condition data corresponding to a specific recipe stored in the recipe information providing server 301 or operation instruction data CD4 based on operation information of the range hood 60 via the network 203 between the cooking appliance 1 and the recipe information providing server 301 and the wireless router 400.

[0030] As an initial setting, the user performs an operation to register identification information such as the model name of the cooking appliance 1. This registration allows the user to acquire 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 information providing server 301. The cloud server 300 has a cloud control unit 303 that controls communications using the network 203 and manages access by the cooking appliance 1 and the second external device 200 to the recipe information providing server 301.

[0031] In addition, the heating cooker 1 can transmit the operating status of the heating cooker 1, such as the "ON" or "OFF" state of the power supply of the heating cooker 1, the heating settings and heating time of each heating means described below, etc., to the cloud server 300 via the network 203, and the second external device 200 can access the cloud server 300 to obtain information on the heating status of the heating cooker 1.

[0032] As mentioned above, the range hood 60 is equipped with a ventilation fan 61 that ventilates the air in the room and a light 62 that illuminates the top plate 3 that covers the top surface of the cooking appliance 1 from above, and further equipped with a receiver unit 63 that receives an operation signal CD5 transmitted from the cooking appliance 1 to operate the ventilation fan 61 and the light 62.

[0033] Cooking appliance 1 has transmitters 25R, 26L for transmitting operation signals CD5 that instruct range hood 60 to operate ventilation fan 61 or lighting 62. In the embodiment of the present disclosure, the operation signals are infrared rays emitted by an infrared LED, but other communication means may be used, such as via wireless router 400. The operation of transmitting operation signal CD5 from cooking appliance 1 will be described later.

[0034] The ventilation fan 61 of the range hood 60 can change and set its airflow speed to one of three levels: "weak," "medium," and "strong." The range hood 60 is also equipped with a timer function that stops the operation of the ventilation fan 61 after a preset time has elapsed since operation (reception of an operating signal). The timer time until stopping can be set to one of three levels, for example, 3 minutes, 5 minutes, or 10 minutes. Note that the fact that the timer time until stopping can be set to three levels, and that these times are 3 minutes, 5 minutes, and 10 minutes, as described in this disclosure, is merely an example; settings of fewer or more than three levels, such as 3 minutes, 5 minutes, or 10 minutes, may also be selected as appropriate.

[0035] The wind speed of the ventilation fan 61 can be adjusted to "weak," "medium," or "strong" using an operation key (not shown) provided on the range hood 60, but the timer time cannot be set using an operation key (not shown) provided on the range hood 60. The timer time can be set by operating the cooking appliance 1 or by operating the second external device 200 via the cooking appliance 1. In this disclosure, the wind speed and timer time are set to three levels, but the number of settings is not limited to three and more levels may be set.

[0036] FIG. 2 is a perspective view showing kitchen furniture 600 accommodating cooking appliance 1 according to embodiment 1 of the present disclosure, and FIG. 3 is a side view showing cooking appliance 1 according to embodiment 1 of the present disclosure. As shown in FIGS. 2 and 3, cooking appliance 1 has a heating section HM including first heating means HM1, second heating means HM2, and third heating means HM3. First heating means HM1 is disposed below top plate 3 covering the upper surface of cooking appliance 1. Second heating means HM2 supplies microwaves to heating chamber 6 formed inside cooking appliance 1. Third heating means HM3 is disposed inside or outside heating chamber 6 and heats the heating chamber 6 by increasing the temperature of the internal space thereof.

[0037] Cooking appliance 1 is a built-in IH cooking heater that is incorporated into kitchen furniture 600, i.e., kitchen furniture, with a cooking table on top. Cooking appliance 1 has a main body 2 and a top plate 3 installed on main body 2. Top plate 3 is exposed on the kitchen countertop that forms the top surface of kitchen furniture 600. Top plate 3 is composed of, for example, a heat-resistant glass plate and a metal frame attached to the periphery of the glass plate. Three heating outlets 4 are provided on the upper surface of top plate 3: a left heating outlet 4L, a right heating outlet 4R, and a center heating outlet 4C.

[0038] The left heating port 4L, the right heating port 4R, and the center heating port 4C indicate areas where metal cooking containers such as pots or frying pans are placed. Metal cooking containers are also referred to as "heated objects" in relation to the first heating means HM1. 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 center heating port 4C are printed on the upper surface of the top plate 3.

[0039] An exhaust port cover 5 is provided on the rear side, that is the farthest part of the top plate 3. The exhaust port cover 5 is made of a punched metal or lattice-shaped metal member with a plurality of 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. A heating door, which is a door 7 that opens and closes the front of the heating chamber 6 located inside the cooking appliance 1, is provided on the front of the main body 2 of the cooking appliance 1. The door 7 is provided with a handle 8 for opening and closing the door.

[0040] As shown in FIG. 3, an induction heating coil (hereinafter referred to as "left IH coil 9L") serving as left induction heating means is provided below the left heating port 4L. Similarly, an induction heating coil (hereinafter referred to as "right IH coil 9R") serving as right induction heating means is provided below the right heating port 4R, and an induction heating coil (hereinafter referred to as "center IH coil 9C") serving as center induction heating means is provided below the center heating port 4C. The left IH coil 9L, right IH coil 9R, and center IH coil 9C are circular heating coils formed by winding thin conductors such as copper or aluminum wire, and generate a high-frequency magnetic field when high-frequency current is supplied to them. This induction heats the objects to be heated, which are cooking containers placed over the left heating port 4L, right heating port 4R, and center heating port 4C.

[0041] The heating means, which includes the left IH coil 9L, right IH coil 9R, and center IH coil 9C, and a drive circuit (not shown) that is a high-frequency power supply circuit such as an inverter circuit that drives them, 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.

[0042] A temperature sensor group 30 (see FIG. 8) consisting of multiple temperature sensors is mounted near the left IH coil 9L, right IH coil 9R, and center IH coil 9C to detect the temperature of the top plate 3 or the object to be heated. One temperature sensor (not shown) constitutes one sensor in the temperature sensor group 30.

[0043] The heating chamber 6 is provided inside the main body 2 below the left IH coil 9L, right IH coil 9R, and center IH coil 9C. The heating chamber 6 is surrounded by metal walls such as stainless steel, and is a space for heating the food and ingredients contained within the heating chamber 6, which are the objects to be cooked.

[0044] The food to be cooked is placed in a heat-resistant plastic container and placed in the heating chamber 6, or on a porcelain or heat-resistant glass plate. In this case, the plate or container is sometimes called the "heated container." Note that since the container is not induction-heated by the left IH coil 9L, right IH coil 9R, or center IH coil 9C, even if it is placed on the heating port 4 of the top plate 3, it is not called the "heated object" for the left IH coil 9L, right IH coil 9R, or center IH coil 9C.

[0045] 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 that it can rotate freely via a hinge (not shown) and an arm (not shown). This allows the door 7 to open forward to a horizontal position with its lower end serving as a fulcrum, i.e., the center of rotation. The door 7 may be pulled forward integrally with a support member (not shown) that supports the container to be heated from below by a slide rail (not shown). The support member is, for example, a structure such as a shelf.

[0046] The door 7 is provided with an open / close detector 10 for detecting whether the door 7 is open or closed. The open / close detector 10 is, for example, a microswitch or an infrared sensor. A microwave oscillator 11 for heating food contained in the heating chamber 6 is provided behind the heating chamber 6.

[0047] Microwave oscillator 11 is composed of, for example, a magnetron, and performs range heating by irradiating microwaves into heating chamber 6 to heat food placed in heating chamber 6. The heating means including microwave oscillator 11 and a drive circuit (not shown) that is a high-frequency power supply circuit such as an inverter circuit that drives it may be referred to as second heating means HM2.

[0048] Additionally, upper radiant heat heating means 12a and lower radiant heat heating means 12b that heat the food from above and below are provided in heating chamber 6. Upper radiant heat heating means 12a is arranged on the ceiling wall surface on the outside or inside of heating chamber 6, and lower radiant heat heating means 12b is arranged on the inside or outside wall surface of heating chamber 6, and both are sheath heaters.

[0049] Other types of radiant heat heating means, such as a mica heater or a carbon heater, may be installed outside the heating chamber 6. FIG. 3 shows an example in which the upper radiant heat heating means 12a and the lower radiant heat heating means 12b are both installed so as to be in close contact with the outer wall surface of the heating chamber 6.

[0050] The heating means including the upper radiant heat heating means 12a, the lower radiant heat heating means 12b, and a drive circuit (not shown) that is a high-frequency power supply circuit such as an inverter circuit that drives them may be referred to as the third heating means HM3. Note that 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.

[0051] Additionally, heating chamber 6 is provided with infrared sensor 13, a non-contact temperature sensor, to detect 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 a group of temperature sensors 30 (see FIG. 8).

[0052] The heating chamber 6 is also provided with a contact-type temperature sensor, such as a thermistor sensor 14, which is an interior temperature sensor that detects the ambient temperature inside the heating chamber 6 or the wall temperature of the heating chamber 6. The thermistor sensor 14 detects temperature by detecting changes in electrical resistance, and therefore the upper limit of the temperature that it can detect is approximately 250°C. The thermistor sensor 14 also constitutes one sensor in the temperature sensor group 30 (see FIG. 8). The 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. 3.

[0053] Fig. 4 is a top view showing the cooking appliance 1 according to the first embodiment of the present disclosure. As shown in Fig. 4, a left operation unit 15L, a central operation unit 15M, and a right operation unit 15R are provided on the front side of the upper surface of the top plate 3 of the cooking appliance 1. These may be collectively referred to as "operation units" or "input operation units," in which case the reference numeral 15 is used. A left heating power display unit 17L, a central display unit 16M, a right heating power display unit 17R, and a left display unit 16L and a right display unit 16R are provided on the rear side, that is, behind the left operation unit 15L, the central operation unit 15M, and the right operation unit 15R.

[0054] 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 16." The center display unit 16M has a horizontally long liquid crystal display screen. The display of the display unit 16 is controlled by the cooking appliance control unit 40, which will be described later, and displays characters and the like based on display signals sent from the cooking appliance control unit 40 to provide notifications.

[0055] The left heating power display unit 17L and the right heating power display unit 17R display the heating power level using light-emitting elements (such as LEDs) and do not have a display screen. 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 unit 17."

[0056] In addition, an operation key 20A for the main power switch 20 is provided adjacent to the right operation unit 15R. The main power switch 20 turns the main power of the cooking appliance 1 "ON" or "OFF." The key that is pressed to switch between "ON" and "OFF" is the operation key 20A. When the main power of the cooking appliance 1 is in the "OFF" state, pressing the operation key 20A for, for example, several seconds turns the main power "ON." In addition, when the main power of the cooking appliance 1 is in the "ON" state, pressing the operation key 20A for, for example, several seconds turns the main power "OFF."

[0057] The central display unit 16M displays information and warnings about the entire cooking appliance 1, and is composed of a liquid crystal display. 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, or the radiant heat heating means (third heating means) HM3. Furthermore, the display screen of the central display unit 16M displays the operating status of each heating means, caution information for cooking with each heating means, or warning information. Although the central display unit 16M is a single liquid crystal display in terms of hardware, it has three display areas: a first display area 22 on the left, a second display area 23 in the center of the left and right, and a third display area 24 on the right, and it is possible to display different information in each display area (see Figure 5).

[0058] Furthermore, first display area 22, second display area 23, and third display area 24 may link together as appropriate depending on the display situation to form a single large display area and display a single purpose. 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. 5, central operation unit 15M has nine input keys: input key 151M, input key 152M, input key 153M, input key 154M, input key 155M, input key 156M, input key 157M, input key 158M, and input key 159M.

[0059] Input keys 151M, input key 152M, input key 153M, input key 154M, input key 155M, input key 156M, input key 157M, input key 158M, and input key 159M are capacitive touch keys. However, the present invention is not limited to this, and keys using push-button mechanical switches may also be used. In addition, individual light-emitting units 21M corresponding to each key are provided near input keys 151M, input key 152M, input key 153M, input key 154M, input key 155M, input key 156M, input key 157M, input key 158M, and input key 159M. Input key 159M, which is used for function setting, allows the user to set various operations and displays of the entire cooking appliance 1 as desired.

[0060] When input key 159M used for function setting is pressed, cooking device control section 40, which will be described later, switches to a "function setting mode" and displays the following "function setting menu" on the display screen of central display section 16M. (1) Child lock setting (setting to disable operation of various input keys). (2) Ventilation fan linkage setting. (3) Operating the ventilation fan. (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) Communication settings (communication connection settings between the communication unit 51 and the wireless router 400). Regarding the above settings, various setting modes can be changed by operating the central operation unit 15M.

[0061] FIG. 5 is a schematic diagram showing a central operation unit 15M of the cooking appliance 1 according to the first embodiment of the present disclosure. As shown in FIG. 5, the central operation unit 15M of the input operation unit 15 is composed of individual light-emitting units 21M and a group of input keys. The individual light-emitting units 21M emit light when the input function of each input key is enabled, and continue to emit light until the input function is disabled. In the central operation unit 15M, an input key 159M for setting a function is located adjacent to the left of the input key 153M. In the first embodiment, an input mode in which the cooking appliance 1 is controlled by a user pressing with a fingertip or the like (including light contact) is referred to as a touch input mode "TM."

[0062] Fig. 6 is a schematic diagram showing the left display unit 16L, left heating power display unit 17L, and left operation unit 15L of the cooking appliance 1 according to the first embodiment of the present disclosure. As shown in Fig. 6, the left display unit 16L displays information related to cooking using the left heating port 4L, and is configured, for example, with a liquid crystal display. The left display unit 16L displays the set time for timer cooking for an object to be heated placed on the left heating port 4L, the elapsed time since the start of heating using the left heating port 4L, or the remaining time until the set timer time expires, etc.

[0063] When preheat cooking is selected for the left heating port 4L, the left display unit 16L displays the automatically set default temperature, the current temperature, etc. The automatically set default temperature refers to the target temperature of the bottom of an object to be heated, such as a metal pot, when it is heated through the left heating port 4L. The default temperature can be changed by the user within a certain range.

[0064] The left heating power indicator 17L is composed of multiple LEDs, which are light-emitting elements, arranged in a horizontal line, and displays the heating power of the left heating port 4L in multiple stages. The left heating power indicator 17L expresses the heating power by switching the lighting state of the multiple LEDs, for example, between on, off, or flashing, or by changing the lighting color. This allows the user to be informed of the heating power in an intuitive and easy-to-understand manner.

[0065] The left operation unit 15L is used to input operations related to cooking using the left heating port 4L. As shown in FIG. 6, the left operation unit 15L has five input keys 151L, 152L, 153L, 154L, and 155L. The input keys 151L, 152L, 153L, 154L, and 155L are, for example, touch-type switches using capacitance-type touch sensors that can input data by utilizing a change in capacitance when the user lightly touches the keys with a finger or the like. However, the present invention is not limited to this, and keys using push-button-type mechanical switches may also be used.

[0066] Individual light-emitting units 21L are provided corresponding to the input keys 151L, 152L, 153L, 154L, and 155L. The individual light-emitting units 21L are made up of LEDs, which are a plurality of light-emitting elements, 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 individual light-emitting unit 21L because they perform the same type of function, i.e., increasing or decreasing the flame power.

[0067] 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. Input key 152L is a key that is pressed when selecting a control menu to be performed for the left heating port 4L. Each time 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, and frying (automatic cooking). The operating time, heat power, operating pattern, etc. of the left heating port 4L differs for each control menu.

[0068] The control menu for the single cooking mode KM1, in which the left heating port 4L and the right heating port 4R are operated by operating the left operation unit 15L or the right operation unit 15R without operating the central operation unit 15M, is entirely induction heating. 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 activates the left IH coil 9L located below the left heating port 4L. If the input key 153L is pressed again while the left IH coil 9L is activated, the activation of the left IH coil 9L is stopped, and the induction heating operation is immediately stopped.

[0069] 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 input key 154L on the left decreases the heat level by one level. Conversely, pressing input key 155L on the right increases the heat level by one level. Note that there are nine heat levels for induction heating cooking at the left heating port 4L, ranging from the minimum rated heat level (heat level 1: 150W) to the maximum rated heat level (heat level 9: 3200W).

[0070] Fig. 7 is a schematic diagram showing a right display unit 16R, a right heating power display unit 17R, and a right operation unit 15R of the cooking device 1 according to the first embodiment of the present disclosure. As shown in Fig. 7, the right display unit 16R displays information related to cooking in the right heating port 4R, and is formed of, for example, a liquid crystal display.

[0071] The information related to cooking using the right heating port 4R displayed on the right display section 16R is the same as the information related to cooking using the left heating port 4L. The right heating power display section 17R is made up of multiple LEDs, which are light-emitting elements, and displays the heating power of the right heating port 4R in multiple stages. Like the left heating power display section 17L, the right heating power display section 17R indicates the heating power by switching the lighting state of the multiple LEDs, which are light-emitting elements, for example, between on, off, or flashing, or by switching the lighting color.

[0072] The right operation unit 15R is used to input operations related to cooking using the right heating port 4R. As shown in Fig. 7, the right operation unit 15R has five input keys 151R, 152R, 153R, 154R, and 155R. The input keys 151R, 152R, 153R, 154R, and 155R are capacitive touch keys that enable input using a change in capacitance when the user lightly touches them with a finger, for example. Individual light-emitting units 21R are provided corresponding to the input keys 151R, 152R, 153R, 154R, and 155R, respectively.

[0073] The individual light-emitting units 21R are LEDs, which are light-emitting elements, and the individual light-emitting units 21R corresponding to the input keys 151R, 152R, 153R, 154R, and 155R respectively emit light in response to the operation of the input keys. However, two adjacent input keys 154R and 155R share one individual light-emitting unit 21R because they perform the same type of function, i.e., increasing or decreasing the flame power.

[0074] Input key 151R is a key that is pressed when selecting timer cooking for the right heating port 4R. Input key 152R is a key that is pressed when selecting a control menu to be performed for the right heating port 4R. Input key 153R is a key that is pressed to start or stop cooking for the right heating port 4R. Input keys 154R and 155R are keys that are pressed when specifying the heat power for cooking for the right heating port 4R. Pressing the left input key 154R decreases the heat power by one level. Conversely, pressing the right input key 155R increases the heat power by one level. The heat power for induction cooking for the right heating port 4R has nine levels, ranging from a rated minimum heat power (heat power level 1) of 150W to a rated maximum heat power (heat power level 9) of 3200W.

[0075] Fig. 8 is a functional block diagram showing the cooking device control unit 40 of the cooking device 1 according to the first embodiment of the present disclosure. As shown in Fig. 8, the cooking device 1 includes the cooking device control unit 40 that performs integrated control of the entire cooking device 1.

[0076] The cooking appliance control unit 40 is an electronic circuit board mounted with electronic components such as a control circuit that controls the operation of each unit constituting the cooking appliance 1. The cooking appliance control unit 40 controls the driving of the left IH coil 9L, the right IH coil 9R, and the center IH coil 9C (not shown) based on the operation of the left operation unit 15L and the right operation unit 15R and the temperature of the object to be heated on the top plate 3.

[0077] The cooking device control unit 40 controls the following operations based on the operation of the central operation unit 15M, the temperature of the object to be heated on the top plate 3, the detection results of the infrared sensor 13, and the detection results of the thermistor sensor 14. For example, it controls the driving of the central IH coil 9C, the microwave oscillator 11, the upper radiant heat heating means 12a, and the lower radiant heat heating means 12b.

[0078] Cooker control unit 40 also controls the displays on left display unit 16L, right display unit 16R, left heating power display unit 17L, and right heating power display unit 17R based on the operation of left operation unit 15L and right operation unit 15R. Cooker control unit 40 also controls the display on central display unit 16M based on the open signal from open / close detection unit 10 and the operation of left operation unit 15L, right operation unit 15R, and central operation unit 15M.

[0079] Cooker control unit 40 has a storage device 41 that stores data such as various programs and parameters used to control cooker 1, and data for the display screens displayed on display units 16L, 16R, 16M, 17L, and 17R. The data for the programs and parameters is collectively referred to as "control data." The data for the display screens displayed on display units 16L, 16R, 16M, 17L, and 17R is collectively referred to as "display condition data."

[0080] Furthermore, the cooking appliance control unit 40 activates the audio notification unit 50 as necessary to audibly notify the user of the operating status of the cooking appliance 1. As mentioned above, the left operation unit 15L, the right operation unit 15R, and the central operation unit 15M may be referred to as the operation unit 15. The operation unit 15 has a key for transitioning to a standby state in which it accepts input of first and second heating conditions from the second external device 200, which is an external communication device described below.

[0081] In the first embodiment of the present disclosure, the keys that transition to the standby state are, for example, input keys 153M and 154M, which are menu keys for selecting a menu, as shown in FIG. 9 described later, and the standby state is transitioned by the first operation of input keys 153M and 154M after the power is turned "ON."

[0082] Cooker control unit 40 stores data in a specific format, which is information such as various programs and parameters used for cooking control by heating control unit 43, in cooking condition data storage unit 42 of storage device 41. This data is the cooking condition data CD mentioned above. "Cooking condition data" and "display condition data" can be acquired by cooker 1 for each cooking menu from second external device 200, which is an external communication device such as a communication terminal.

[0083] The cooking condition data storage unit 42 stores "cooking condition data" and "display condition data." The cooking condition data storage unit 42 may constitute a section, i.e., an area, of the storage device 41, or may be configured as a separate unit from the storage device 41 in terms of hardware.

[0084] The heating control unit 43 performs integrated control of the overall heating operation of the cooking appliance 1, and is mainly composed of a microcomputer. The data acquisition unit 53 acquires "cooking condition data" from the second external device 200 or the cloud server 300 via the communication unit 51. The data acquisition unit 53 may also acquire "display condition data" from the second external device 200 or the cloud server 300, which is external communication, via the communication unit 51. The communication unit 51 communicates wirelessly with the outside, and has the function of performing wireless communication with the second external device 200 or the cloud server 300 via the wireless router 400 as shown in FIG. 1. In the cooking appliance control unit 40, the communication control unit 44 performs processing related to communication with the communication unit 51. Here, the communication control unit 44 particularly performs processing related to the communication setting mode.

[0085] The power supply circuit 57 supplies a constant voltage of power to the cooking appliance control unit 40. The main power switch 20 is a main power switch inserted into the power supply circuit 57. The restriction unit 55 restricts the acquisition of cooking condition data. If the data acquired by the data acquisition unit 53 is invalid data or if the heating setting by the second external device 200, which is an external communication device, is invalid, the restriction unit 55 discards the data. Note that the restriction unit 55 may be realized by a single control program of a computer (not shown) that constitutes the cooking appliance control unit 40, and it is not necessarily required that the restriction unit 55 be configured as hardware separate from the cooking appliance control unit 40.

[0086] Fig. 9 is a schematic diagram showing central operation unit 15M of cooking device 1 according to embodiment 1 of the present disclosure. As shown in Fig. 9, input keys 153M and 154M have a function of descending and ascending for menu selection. Furthermore, input keys 155M and 156M have a function of descending and ascending for heat power selection. Furthermore, input keys 157M and 158M have a function of descending and ascending for time selection.

When input key 151M is then pressed, cooking begins.

[0091] FIG. 12 is a table showing the setting ranges of the setting conditions of the cooking system 1a according to the first embodiment of the present disclosure. As shown in FIG. 12, there are heating menus, setting conditions, and setting ranges as examples of modes of the cooking device 1. The heating menu includes "warm," "manual microwave," "parboil leafy vegetables," "parboil root vegetables," "thaw meat," "grill," "fillet," "grill," and "oven." The setting condition for "warm" is temperature, and the setting range is 0°C to 90°C in 5°C increments. The setting condition for "manual microwave" is power and time, and the setting ranges are 200W: 10 seconds to 60 minutes, 300W: 10 seconds to 60 minutes, and 500W: 10 seconds to 15 minutes. 10 seconds to 5 minutes: 10 second increments, 5 minutes to 10 minutes: 30 second increments, 10 minutes to 60 minutes: 1 minute increments, and 60 minutes to 120 minutes: 5 minute increments.

[0092] The setting conditions for "Parboiling leafy vegetables," "Parboiling root vegetables," "Defrosting meat," "Grilling whole meat," and "Fillet" are heat levels, with setting ranges of low, slightly low, standard, slightly high, and high. The setting conditions for "Grill" are time, ranging from 10 seconds to 30 minutes. Note that 10 seconds to 5 minutes are set in 10-second increments, 5 minutes to 10 minutes are set in 30-second increments, 10 minutes to 60 minutes are set in 1-minute increments, and 60 minutes to 120 minutes are set in 5-minute increments. The setting conditions for "Oven" are temperature and time. The setting ranges for temperature are 30°C, 40°C, and 80°C to 250°C are set in 10°C increments, and the setting range for time is 10 seconds to 120 minutes. Note that 10 seconds to 5 minutes are set in 10-second increments, 5 minutes to 10 minutes are set in 30-second increments, 10 minutes to 60 minutes are set in 1-minute increments, and 60 minutes to 120 minutes are set in 5-minute increments.

[0093] The heating menu, setting conditions, and setting ranges are not limited to those described above, and other heating menus, setting conditions, and setting ranges may be used.

[0094] Fig. 13 is a list of setting conditions corresponding to heating menus of the heating cooking system 1a according to the first embodiment of the present disclosure and their initial values. As shown in Fig. 13, an initial value is set for each setting condition of the heating menu. The initial value may be the value previously used for the target heating menu. Types of notification of setting conditions include "Please enter temperature," "Please enter power," "Please enter heat level," "Please enter heat power," and "Please enter time."

[0095] (control, operation) Next, the functions of the cloud control unit 303 will be described in detail. Depending on the heating menu, it may be necessary to input multiple setting conditions. In the following description, the heating menu will be referred to as the first heating condition, setting condition (1) as the second heating condition, and setting condition (2) as the third heating condition.

[0096] When the cloud control unit 303 receives a notification from the cooking appliance 1 that the user has performed a specific operation to put the cooking appliance 1 into a standby state for voice input, the cloud control unit 303 first notifies the second external device 200, which is an external communication device, of a notification of input guidance for the first heating conditions, which are a heating menu. After receiving input information for the first heating conditions from the second external device 200, the cloud control unit 303 notifies of a notification of input guidance for the second heating conditions. The processing of the cloud control unit 303 may be performed by the cooking appliance control unit 40 or the control device 100.

[0097] As an example, the first heating condition of the cooking device 1 is a heating menu indicating the type of heating, and the second and third heating conditions are each one of heating power, power, temperature, time, and heat level. The second and third heating conditions vary depending on the input first heating condition, and the input guide for the second and third heating conditions vary depending on the type of the second and third heating conditions.

[0098] Figure 14 shows the operation display for range hood 60 using "ventilation fan operation" in "function setting mode." Right transmitter 25R is located to the right of central display 16M, and left transmitter 25L is located to the left. Transmitters 25R and 25L are equipped with elements (such as LEDs) that emit infrared light, and are controlled by cooker control unit 40 in the same way as individual light-emitting unit 21M. In cooker 1 of the present disclosure, transmitters are located in two places on central display 16M, but they may be located in other areas, including right display 16R and left display 16L, and the number may be three or more.

[0101] When input key 156M is operated, an operation signal CD5 for range hood 60 can be transmitted from both left and right transmitters 25R and 25L. For example, when input key 156M is operated, a signal to operate the exhaust fan at a "medium" air speed is transmitted, and when input key 158M is operated, a signal to turn the light "on" is transmitted. When input key 155M is operated, a signal to "stop" the exhaust fan is transmitted, and when input key 158M is operated, a signal to "turn off" the light is transmitted.

[0102] 14(c) shows the display of central display unit 16M in "ventilation fan interlocking" in "function setting mode." In the "ventilation fan interlocking" setting, two settings can be changed: "heating interlocking," which switches between enabling and disabling the automatic transmission of operation signal CD5 in response to the heating operation of cooking appliance 1, and "smartphone interlocking," which switches between enabling and disabling the reception of operations related to range hood 60 from second external device 200, which is an external communication device such as a smartphone.

When the setting value is "ON," operating input key 158M selects the setting value "OFF," and the bottom of the third display area 24 displays "OFF" large and "ON" small.

[0106] After changing the setting value, the change in setting is confirmed by operating input key 151. To return the setting to "ON" again, select "Ventilation Fan Interlock" in "Function Setting Mode" and operate input key 157M to select the setting value "ON," and then operate input key 151 to confirm the change in setting.

[0107] FIG. 15(a) is a screen for operating the ventilation fan 61 and the light 62 by the second external device 200, displayed on the external device display unit 200a of a smartphone which is the second external device 200 that is an external communication device. The lighting 62 can be set to "ON" with the lighting "ON" key 201b, and to "OFF" with the lighting "OFF" key 201a. The wind speed "weak" can be set with the wind speed "weak" key 201d, the wind speed "medium" can be set with the wind speed "medium" can be set with the wind speed "strong" key 201f, and the ventilation fan "OFF" key 201c can be set to "OFF" with the ventilation fan 61. The timer "set 3 minutes" key 201i can be used to set the timer time to "3 minutes", the timer "set 5 minutes" key 201j can be used to set the timer time to "5 minutes", the timer "set 10 minutes" key 201k can be used to set the timer time to "10 minutes", and the timer "OFF" key 201h can be used to set the timer time of the operating ventilation fan 61 to "OFF". After each setting has been confirmed, the setting can be transmitted with the send key 201g.

[0108] The selectable settings for each item are displayed in black letters on a white background, and the currently selected setting is displayed in white letters on a black background. In Figure 15(a), the wind speed "weak" and timer "5 minutes" are selected.

[0109] When the "send" key is operated while any of the setting values ​​is selected, a pop-up display 200b notifying that transmission is in progress is displayed on the external device display unit 200a of the second external device 200, with the words "sending" as shown in Fig. 15(b). At this time, the second external device 200 is sending information about the setting values ​​of the ventilation fan 61 and the lighting 62 of the range hood 60, which is the selected first external device, to the cooking appliance 1 via the cloud server 300.

[0110] 15(c), a pop-up display 200c notifying the completion of the transmission displays the message "Transmission Completed" on the external device display unit 200a of the second external device 200. Note that, although the example in which "Transmission Completed" is displayed when the transmission is completed has been described here, the present invention is not limited to this. For example, after the transmission is completed, the second external device 200 may display the message after receiving a notification of completion of transmission of the operation signal for the ventilation fan 61 from the cooking appliance 1.

[0111] In addition, although the example described here is one in which operation input is performed by operating input keys displayed on the external device display unit 200a of a smartphone, which is the second external device 200 that is an external communication device, the present invention is not limited to this, and operation input may be performed by voice from a voice input unit (not shown) of the second external device 200. Operation by voice allows operation even when the user is busy holding cooking utensils or when the user's fingers are dirty and unable to operate the input keys displayed on the external device display unit 200a of the smartphone, which is the second external device 200, thereby improving usability.

[0112] 15(c) has described an example in which transmission is completed without any problems, but there are cases in which transmission is not possible (transmission fails) due to a communication failure, malfunction of the device, or the like. As described above, when second external device 200 is configured to receive and then display a notification of completion of transmission of the operation signal for ventilation fan 61 from cooking appliance 1 after transmission is completed, timing means (not shown) measures the time from the start of transmission, and if second external device 200 does not receive (cannot receive) the notification of completion of transmission of the operation signal for ventilation fan 61 from cooking appliance 1 even after a preset communication time has elapsed, as shown in FIG. 15(d), a pop-up display 200d notifying that transmission was not possible (transmission failed) may be displayed on external device display unit 200a of second external device 200 by displaying the text "Transmission Failed" to indicate that transmission was not possible (transmission failed).

[0113] 16 is a state transition diagram showing behavior when a heating operation is performed by the cooking appliance 1 when "heating interlock" is "ON." When a user performs an operation to turn the power supply "ON" for the cooking appliance 1, a signal (A11) to turn the power supply "ON" is sent to the heating control unit 43 of the cooking appliance 1, and the power supply for the cooking appliance 1 is turned "ON."

[0114] After the power supply of the cooking appliance 1 is turned "ON," for example, when the input key 151M is operated to start cooking using the radiant heat heating means 12, which is a heat source for heating the heating chamber 6, a signal (A12) to start heating using the radiant heat heating means 12 is sent to the heating control unit 43 of the cooking appliance 1, and the radiant heat heating means 12 is driven to start heating.

[0115] When heating is started in the cooker 1, the heating control unit 43 causes the left and right transmitters 25L, 25R of the cooker 1 (see FIGS. 14(a) to 14(c)) to transmit a signal (B12) to the exhaust fan 61 of the range hood 60, which is the first external device, to operate the exhaust fan 61 at a "medium" air speed. Note that the signal (B12) for operating the exhaust fan 61 of the range hood 60 at a "medium" air speed described here is the same as the operation signal CD5 transmitted from the cooker 1 to the exhaust fan 61 of the range hood 60 and the light 62 shown in FIG. 1. In FIG. 1, the operation signals transmitted from the cooker 1 to the exhaust fan 61 of the range hood 60 and the light 62 are all shown as operation signal CD5, but individual operation signals may be, for example, the signal (B12) for operating the exhaust fan 61 at a "medium" air speed shown in FIG. 16 as described above. Hereinafter, the signals transmitted from the cooking appliance 1 to the exhaust fan 61 of the range hood 60 and the lighting 62 may be expressed as individual signals, such as the signal (B12) for operating the exhaust fan 61 at a "medium" wind speed, but unless otherwise specified, these individual signals will be treated as the same as the operation signal CD5 transmitted from the cooking appliance 1 to the exhaust fan 61 of the range hood 60 and the lighting 62 shown in Figure 1.

[0116] In addition, in the explanation here, the airflow speed of the ventilation fan 61 operating in "heating interlocking" is "medium," but it is not limited to this and may be "strong" or "weak." Furthermore, although the explanation here is given of an example in which heating is started by the radiant heat heating means 12, which is the heat source for heating the heating chamber 6, the heat source that starts heating may be any of the induction heating sources 9 corresponding to any of the heating ports 4 on the top plate.

[0117] When the user selects the "ventilation fan operation" mode of the cooking appliance 1 shown in Figure 14(b), a display related to the lighting corresponding to the lighting 62 of the range hood 60 is displayed in the third display area 24, the "OFF" display is displayed in the OFF display area 24a, and the "ON" display is displayed in the ON display area 24b.

[0118] The operation key corresponding to the display of "OFF" is input key 157M, and when input key 157M is operated while light 62 of range hood 60 is on, a signal (B15) for turning off light 62 as shown in FIG. 16 is transmitted from left and right transmitters 25L, 25R of heating cooker 1 (see FIGS. 14(a) to (c)) by heating control unit 43 of heating cooker 1 to light 62 of range hood 60, and when receiver 63 of range hood 60 receives signal (B15) (operation signal CD5 in FIG. 1), light 62 is turned off.

[0119] The operation key corresponding to the display of "ON" is input key 158M, and when input key 158M is operated while light 62 of range hood 60 is off, heating control unit 43 of cooking appliance 1 transmits a signal (B13) to light 62 of range hood 60 from left and right transmitters 25L, 25R (see Figures 14(a) to (c)) of cooking appliance 1 to light 62 of range hood 60 as shown in Figure 16 to turn on light 62, and when receiver 63 of range hood 60 receives signal (B13) (operation signal CD5 in Figure 1), light 62 turns on.

[0120] When the user operates input key 152M while heating is being performed by radiant heat heating means 12, which is the heat source for heating heating chamber 6, heating stops. Input key 152M is a cancel key that can cancel the operation (see FIG. 9). When heating stops, transmitters 25L and 25R (see FIGS. 14(a) to 14(c)) transmit a signal (B14) to exhaust fan 61 of range hood 60 to set the timer time from when heating stops until the exhaust fan 61 stops in a delayed manner to 5 minutes. Note that in the description here, the timer time from when heating stops until the exhaust fan 61 stops in a delayed manner is set to 5 minutes, but this is not limited to this and other times, such as 3 minutes or 10 minutes, may be set. The reason for delaying the stop of exhaust fan 61 after heating stops is to prevent post-cooking odors and hot air from remaining even after heating stops. However, exhaust fan 61 may also be stopped immediately after heating stops.

[0121] After the heating of the cooking appliance 1 has stopped, when the input key 157M of the operation key corresponding to "OFF" displayed in the OFF display area 24a of the third display area 24 is operated from the "ventilation fan operation" mode of the cooking appliance 1 shown in Figure 14(b), as described above, the transmitters 25L, 25R (see Figures 14(a) to (c)) transmit a signal (B15) to the light 62 of the range hood 60 to turn off the light 62, as shown in Figure 16, and when the receiver 63 of the range hood 60 receives the signal (B15) (operation signal CD5 in Figure 1), the light 62 is turned off.

[0122] As described above, when "heating interlocking" is "ON," the cooking appliance 1 sends operation signals to the exhaust fan 61 of the range hood 60 to drive and stop the exhaust fan 61 or stop it by timer in accordance with the start and stop of heating, thereby enabling the user to operate the exhaust fan 61 without having to operate the operation keys (not shown) of the range hood 60 or the "exhaust fan operation" mode, thereby improving usability. Note that in the present disclosure, only the operation of the exhaust fan 61 is interlocked with the start or stop of heating, but the operation of the light 62 may also be configured to turn on when heating starts and turn off when heating stops.

[0123] 17 is a state transition diagram showing the behavior when the heating operation of the cooking appliance 1 is operated using the cooking appliance 1 and a second external device 200, which is an external communication device such as a smartphone, when both "heating interlocking" and "smartphone interlocking" are "ON". As when only "heating interlocking" is "ON", when the input key 151M is operated to start cooking using the radiant heat heating means 12, which is the heat source for heating the heating chamber 6, a signal (A12) to start heating using the radiant heat heating means 12 is sent to the heating control unit 43 of the cooking appliance 1, and the radiant heat heating means 12 is driven to start heating.

[0124] When heating begins in the cooking appliance 1, the heating control unit 43 transmits a signal (B12) from the left and right transmitters 25L and 25R (see Figures 14(a) to (c)) of the cooking appliance 1 to the ventilation fan 61 of the range hood 60 to operate the ventilation fan 61 at a "medium" wind speed.

[0125] When "Smartphone Link" is "ON", operations that were previously performed from the cooking appliance 1 can also be performed from the second external device 200. Operations from the second external device 200 are not received directly by the cooking appliance 1, but are received by the cooking appliance 1 via the cloud server 300 and the home wireless router 400 as shown in FIG. 1. More specifically, the communication unit 51 of the cooking appliance 1 receives the operations.

[0126] 15(a), an illumination "ON" key 201b, which is an input key for turning on the illumination 62 and is displayed on the external device display unit 200a of the second external device 200, which is an external communication device, is operated. At this time, a signal (A16) indicating that the illumination "ON" key 201b of the second external device 200 has been operated is transmitted to the control unit of the second external device 200, although this is not shown in the figure.

[0127] Next, the wind speed "strong" key 201f, which is an input key for changing the wind speed of the ventilation fan 61 to "strong," is operated. At this time, a signal (A17) indicating that the wind speed "strong" key 201f of the second external device 200 has been operated is also transmitted to the control unit of the second external device 200, although this is not shown in the figure.

[0128] Thereafter, when the transmission key 201g is operated, a signal (C16) for turning on the light 62 by operation from the second external device 200 is transmitted to the cooking appliance 1 as shown in Fig. 17, and a signal (B13) for turning on the light 62 is transmitted from the transmitting units 25L, 25R (see Figs. 14(a) to (c)) of the cooking appliance 1 to the receiving unit 63 of the range hood 60 shown in Fig. 1 as shown in Fig. 17, and when the receiving unit 63 of the range hood 60 receives the signal (B13) (operation signal CD5 in Fig. 1), the light 62 is turned on. Note that in Fig. 17, the signal for turning on the light 62 transmitted from the second external device 200 to the cooking appliance 1 is shown as C16, but more specifically, as shown in Fig. 1, condition data CD3 is transmitted from the second external device 200 to the cloud server 300, and is transmitted from the cloud server 300 to the cooking appliance 1 via the wireless router 400 as operation instruction data CD4.

[0129] Furthermore, as shown in FIG. 17, a signal (C17) for changing the airflow speed of the ventilation fan 61 to "high" is transmitted to the cooking appliance 1 by operation from the second external device 200, and a signal (B16) for changing the airflow speed of the ventilation fan 61 to "high" is transmitted from the transmitting units 25L, 25R (see FIGS. 14(a) to (c)) of the cooking appliance 1 to the receiving unit 63 of the range hood 60 shown in FIG. 1, as shown in FIG. 17, and when the receiving unit 63 of the range hood 60 receives the signal (B16) (operation signal CD5 in FIG. 1), the airflow speed of the ventilation fan 61 is changed to "high." In Figure 17, the signal C17 is sent from the second external device 200 to the cooking appliance 1 to set the wind speed of the ventilation fan 61 to "high." In more detail, as shown in Figure 1, the condition data CD3 is sent from the second external device 200 to the cloud server 300, and is then sent from the cloud server 300 to the cooking appliance 1 via the wireless router 400 as operation instruction data CD4.

[0130] When the transmission of the signal is completed, the communication unit 51 of the cooking appliance 1 transmits a signal (B17) notifying that the ventilation fan operation signal transmission is complete to the second external device 200. Although not shown, in this case as well, the ventilation fan operation signal transmission completion notification is transmitted from the cooking appliance 1 via the wireless router 400 and the cloud server 300 to the second external device 200. When the second external device 200 receives the ventilation fan operation signal transmission completion notification signal (B17), as shown in FIG. 15(c), the external device display unit 200a of the second external device 200 displays a pop-up display 200c notifying that the transmission is complete, with the text "Transmission Completed" indicating that the transmission is complete. By looking at the display of the second external device 200, it is possible to confirm that the operation from the second external device 200 has been completed without directly looking at the ventilation fan 61 of the range hood 60 or the light 62.

[0131] Note that, although the example described here is one in which operation input is performed by operating input keys displayed on the external device display unit 200a of the smartphone, which is the second external device 200, the present invention is not limited to this, and operation input may be performed by voice from a voice input unit (not shown) of the second external device 200. With voice operation, even when the user is holding cooking utensils and cannot use their hands, or when their fingers are dirty and they cannot operate the input keys displayed on the external device display unit 200a of the smartphone, which is the second external device 200, it is possible to change the airflow speed of the ventilation fan 61 and turn the light 62 on and off, thereby improving usability.

[0132] Fig. 18(a) is an example of the display on central display unit 16M when heating is performed at "fillet" and "standard" when cooking fish using heating chamber 6. As described above, when the air speed of exhaust fan 61 of range hood 60 is changed to "high" and light 62 is turned on by operation from second external device 200, external device display unit 200a of second external device 200 displays pop-up display 200c notifying that the transmission has been completed, saying "Transmission completed." However, as shown in Fig. 18(b), central display unit 16M of cooking appliance 1 may display that the air speed of exhaust fan 61 has been changed to "high" and light 62 has been turned on.

[0133] By displaying this information on the central display unit 16M of the cooking appliance 1 in this manner, even if the user who is cooking near the cooking appliance 1 and the user who operates the second external device 200 to change the airflow speed of the ventilation fan 61 to "high" and turn on the light 62 are different users, it is possible to let the user know that the second external device 200 has been operated to change the airflow speed of the ventilation fan 61 to "high" and that the light 62 has been turned on, thereby eliminating any sense of incongruity about the changes.

[0134] The central display 16M of the cooking appliance 1 shown in Figure 18(b) indicates that the airflow speed of the ventilation fan 61 has been changed to "high" and the light 62 has been turned on, but after a certain period of time, for example 5 seconds, the original display, i.e., the display when cooking fish using the heating chamber 6 shown in Figure 18(a) and heating at "fillet" or "standard" setting, is restored.

[0135] Here, the central display unit 16M of the cooking appliance 1 displays the information that the air speed of the ventilation fan 61 has been changed to "high" and the light 62 has been turned on, but the information may also be provided by audio from the audio notification unit 50 of the cooking appliance 1 (see Figure 8), or by both display and audio.

[0136] When the user operates input key 152M while heating is being performed by radiant heat heating means 12, which is the heat source for heating heating chamber 6, heating stops as shown in FIG. 17. Input key 152M is a cancel key that can cancel an operation (see FIG. 9). When heating stops, a signal (B14) is sent from transmitters 25L and 25R (see FIGS. 14(a) to (c)) to exhaust fan 61 of range hood 60 to set the timer time from when heating stops until the exhaust fan 61 stops in a delayed manner to 5 minutes. If the user wants to change the timer time until the exhaust fan 61 stops to, for example, 10 minutes, this can be changed by operating timer "10 minute setting" key 201k shown in FIG. 15.

[0137] 15(a), the timer "10 minutes set" key 201k displayed on the external device display unit 200a of the second external device 200 is operated. At this time, a signal (A16) indicating that the illumination "ON" key 201b of the second external device 200 has been operated is transmitted to the control unit of the second external device 200, although this is not shown.

[0138] After that, when the transmission key 201g is operated, a signal (C18) for changing the timer time until the ventilation fan 61 is stopped to 10 minutes by operation from the second external device 200 is transmitted to the cooking appliance 1 as shown in FIG. 17, and a signal (B18) for changing the timer time until the ventilation fan 61 is stopped to 10 minutes is transmitted from the transmitting units 25L, 25R (see FIGS. 14(a) to (c)) of the cooking appliance 1 to the receiving unit 63 of the range hood 60 shown in FIG. 1 as shown in FIG. 17, and when the receiving unit 63 of the range hood 60 receives the signal (B18) (operation signal CD5 in FIG. 1), it resets the timer time from "5 minutes" to "10 minutes" and stops the operation of the ventilation fan 61 10 minutes after the receiving unit 63 receives the signal (B18).

[0139] As described above, by transmitting an operation signal from the second external device 200 to the receiver 63 of the range hood 60 via the cooking appliance 1, it becomes possible to operate the exhaust fan 61 and the light 62, and when the range hood 60 is operating after cooking is finished, the exhaust fan 61 and the light 62 of the range hood 60 can be operated by the second external device 200 from a location other than the kitchen, improving usability. Furthermore, by allowing operation input by voice from the voice input unit of the second external device 200, even if the cooking appliance 1 or the range hood 60 themselves do not support voice operation, or even if one is unable to use one's fingers, the exhaust fan 61 and the light 62 of the range hood 60 can be operated by voice from the second external device 200, improving usability.

[0140] Figure 19 is a state transition diagram showing the behavior when the ventilation fan 61 of the range hood 60 is operated by the second external device 200 after the power of the cooking appliance 1 main body is turned "OFF," and Figure 20 is a screen showing the operation of the ventilation fan 61 and the light 62 by the second external device 200, displayed on the external device display unit 200a of the second external device 200, which is an external communication device, a smartphone, when the power of the cooking appliance 1 main body is "OFF."

[0141] When the power of the cooking appliance 1 main body is "ON," as described above, the lighting 62 can be set "ON" with the lighting "ON" key 201b, and "OFF" with the lighting "OFF" key 201a. The wind speed can be set to "weak" with the wind speed "weak" key 201d, to "medium" with the wind speed "medium" with the wind speed "strong" key 201f, to "strong" with the wind speed "strong" with the ventilation fan "OFF" key 201c. The timer time can be set to "3 minutes" with the timer "3-minute setting" key 201i, to "5 minutes" with the timer "5 minutes setting" key 201j, to "10 minutes" with the timer "10-minute setting" key 201k, and the timer time of the operating ventilation fan 61 can be set to "OFF" with the timer "OFF" key 201h. After each setting has been confirmed, the setting can be transmitted with the send key 201g.

[0142] When the power supply of the cooking appliance 1 main body is "OFF," as shown in FIG. 20, the lighting "ON" key 201b for turning on the lighting 62 on the second external device 200 is grayed out and cannot be operated, whereas the lighting "OFF" key 201a for turning off the lighting 62, i.e., turning off the lighting 62, is valid and can be operated.

[0143] Furthermore, the wind speed "weak" key 201d, wind speed "medium" key 201e, and wind speed "strong" key 201f, which change the wind speed of the ventilation fan 61, are grayed out and cannot be operated, whereas the ventilation fan "OFF" key 201c, which turns the wind speed of the ventilation fan 61 "OFF," i.e., stops the ventilation fan 61, is valid and can be operated.

[0144] Furthermore, in FIG. 20, the timer "set to 3 minutes" key 201i, timer "set to 5 minutes" key 201j, timer "set to 10 minutes" key 201k, which are used to set the timer time, as well as the timer "OFF" key 201h, which is used to turn off the timer time of the operating ventilation fan 61, are grayed out, and all timer-related operations are disabled.

[0145] When the power of the cooking appliance 1 main body is "OFF," cooking is often finished and the exhaust fan 61 of the range hood 60 has already stopped. When the exhaust fan 61 is stopped, it is possible that the fan of the exhaust fan 61 has been removed for cleaning or the like. In such a case, if another user were to allow an instruction to operate the exhaust fan 61 from the second external device 200, there is a risk that the user removing the fan of the exhaust fan 61 could be injured. Therefore, when the power of the cooking appliance 1 main body is "OFF," operations to turn the fan "ON" from the second external device and operations to change the operating conditions are prohibited.

[0146] When the user performs an operation to "OFF" the power supply of the cooking appliance 1, a signal (A19) to "OFF" the power supply is sent to the heating control unit 43 of the cooking appliance 1, and the cooking appliance 1 is turned "OFF." When the cooking appliance 1 is turned "OFF," the cooking appliance control unit 40, although not shown, sends information from the communication unit 51 to the cloud server 300 that the cooking appliance 1 has been turned "OFF."

[0147] The second external device 200 periodically accesses the cloud server 300 to update information about the power "ON" or "OFF" state of the cooking appliance 1 and the heating state stored in the device control unit 100 in the second external device 200. However, due to the timing of the update, the line conditions of the network 203 (see FIG. 1), update delays, etc., the power "ON" or "OFF" state of the cooking appliance 1 may not match the information about the power "ON" or "OFF" state of the cooking appliance 1 stored in the device control unit 100. When the information does not match, even if the power of the cooking appliance 1 is in the "OFF" state, some of the operation keys may not be disabled in the second external device 200 as in the operation screen displayed on the external device display unit 200a shown in FIG. 20, and all operation keys may be enabled and operable as in the operation screen displayed on the external device display unit 200a shown in FIG. 15(a).

[0148] When the information does not match in this way, as shown in Figure 19, even if an operation to change or set the wind speed is performed on the second external device 200, for example, the wind speed "strong" key 201f is operated to set the wind speed to "strong," a signal (A17) is sent to the second external device 200, a signal (C17) to set the wind speed of the ventilation fan 61 to "strong" is sent from the second external device 200 to the cooking appliance 1, and the cooking appliance 1 receives the wind speed "strong" at its communication unit 51, the cooking appliance control unit 40 determines that the setting operation to set the wind speed of the ventilation fan 61 to "strong" is an invalid operation, and sends a signal (B19) from the communication unit 51 to the second external device 200 notifying that the transmission of the ventilation fan operation signal has failed.

[0149] When the second external device 200 receives the ventilation fan operation signal transmission failure notification signal (B19), as shown in Fig. 15(d), a pop-up display 200d notifying that transmission was not possible (transmission failed) is displayed on the external device display unit 200a of the second external device 200, with the text "Failed to transmit" to indicate that transmission was not possible (transmission failed). Note that although the fact that transmission was not possible (transmission failed) is notified or announced by a display here, it may also be announced by a sound from the second external device 200.

[0150] After that, the "ON" or "OFF" state of the power supply of the cooking appliance 1 matches the "ON" or "OFF" state information of the power supply of the cooking appliance 1 stored in the device control unit 100, and the operation screen is updated to one in which some of the operation keys are disabled, as shown in the operation screen displayed on the external device display unit 200a of the second external device 200 shown in Figure 20, and only the operation of the light "OFF" key 201a, which turns "OFF" the light 62, i.e., turns off the light 62, and the ventilation fan "OFF" key 201c, which turns "OFF" the airflow speed of the ventilation fan 61, i.e., stops the ventilation fan 61, becomes valid.

[0151] As described above, even if the power of the cooking appliance 1 is "OFF" due to the timing of the update, the line conditions of the network 203 (see Figure 1), update delays, etc., and the update of the operation screen displayed on the external device display unit 200a of the second external device 200 is delayed, and when the power of the cooking appliance 1 is "OFF," even if an operation such as changing the wind speed of the ventilation fan 61 is performed on the operation screen displayed on the external device display unit 200a of the second external device 200 before the update, the cooking appliance control unit 40 of the cooking appliance 1 determines whether the contents of the operation signal CD5 received by the communication unit 51 are valid / invalid depending on the "ON" or "OFF" state of the power of the cooking appliance 1, thereby preventing operations that are dangerous to the user.

[0152] In the present disclosure, when the power supply of the cooking appliance 1 is in the "OFF" state, the operation of turning on the light 62 by the second external device 200, i.e., turning on the light 62, is also prohibited. However, since turning on the light 62 is highly unlikely to pose a danger to the user compared to an operation that changes the operation of the ventilation fan 61, it may be possible to turn on the light 62, i.e., to turn on the light 62, even when the power supply of the cooking appliance 1 is in the "OFF" state.
