Description

Technical Field

[0001] The present disclosure relates to a cooking appliance.

Background Art

[0002] It may be connected to a network using wireless communication. Patent Document 1 describes one type of method for connecting to an access point. Specifically, the access point disclosed in Patent Document 1 connects a wired LAN and an external wireless LAN terminal based on a predetermined wireless LAN standard. The barcode reader of the access point includes an LED element, a phototransistor, and a decoder. Normally, the LED element displays the operating status of the access point. When reading a barcode, the LED element blinks at a predetermined frequency. The phototransistor receives the reflected light from the barcode of the irradiation light of the LED element and converts it into an electrical signal. The decoder decodes the barcode based on the electrical signal from the phototransistor. The barcode reader acquires first ID data from the barcode attached to the external wireless LAN terminal when reading the barcode. When there is a connection request from the wireless LAN terminal, the access point acquires the MAC address and second ID data sent from the wireless LAN terminal along with the connection request. The access point determines whether the first ID data and the second ID data match. When it is determined that the first ID data and the second ID data match, the access point distributes an encryption key for use in encrypting data to the wireless LAN terminal and registers the acquired MAC address.

Summary of the Invention

Problems to be Solved by the Invention

[0004] When connecting to a network via a wireless communication access point (base station), the cooking appliance needs to be authenticated by the access point. Also, in order for the cooking appliance to obtain data from a server on the network, the information for connecting to the access point may not be sufficient in some cases. Conventionally, a mobile communication device such as a smartphone has been used for setting up wireless communication in a cooking appliance. For example, the user downloads a setting application and installs it on the mobile communication device. Along with the display and instructions based on the application, the user repeatedly manually enters information for wireless communication into the mobile communication device. Based on the manually entered information, the access point and the cooking appliance are set up. However, a series of information input and setting operations using a mobile communication device is time-consuming. There are also people who are not good at setting up using a mobile communication device.

[0005] An aspect of the present disclosure aims to provide a cooking appliance that does not require complicated button operations, can perform connection settings for wireless communication even without a mobile communication device, and is easy to set up for communication.

Means for Solving the Problem

[0006] A cooking appliance according to an aspect of the present disclosure includes a heating chamber having an accommodation space for receiving an object to be heated, a door for opening and closing the heating chamber, a wireless communication unit, a reader having an imaging unit for reading a code into which information has been converted, and a connection execution unit that causes the wireless communication unit to communicate with a wireless base device as an access point when the code read by the reader includes connection setting information, and establishes a connection between the wireless communication unit and the wireless base device based on the connection setting information.

Mode for Carrying Out the Invention

[0008] Hereinafter, with reference to the drawings, one aspect of the cooking heater 1 according to the present disclosure will be described. For example, the cooking heater 1 is a microwave oven. In the drawings, the same or equivalent elements are denoted by the same reference numerals.

[0009] (Cooking heater 1) First, with reference to FIGS. 1 to 3, an example of the cooking heater 1 according to the embodiment will be described. FIGS. 1 to 3 are diagrams showing an example of the cooking heater 1 according to the embodiment. FIG. 1 shows an example of a state where the door 101 is closed. FIG. 2 shows an example of a state where the door 101 is opened.

[0010] In the following description, as shown in FIGS. 1 and 2, the directions may be described using a three-dimensional orthogonal coordinate system (XYZ coordinate system). In the following description, the X-axis direction is the left-right direction of the cooking heater 1 when the cooking heater 1 installed on the horizontal plane is viewed from the front (front). The +X direction is the right side of the cooking heater 1, and the -X direction is the left side. The Y-axis direction is the front-rear direction of the cooking heater 1 when the cooking heater 1 installed on the horizontal plane is viewed from the front. The +Y direction is the back side of the cooking heater 1, and the -Y direction is the front side. The Z-axis direction is the up-down direction of the cooking heater 1 when the cooking heater 1 installed on the horizontal plane is viewed from the front. The +Z direction is the upper side of the cooking heater 1, and the -Z direction is the lower side. The X-axis direction and the Y-axis direction are orthogonal, the Y-axis direction and the Z-axis direction are orthogonal, and the X-axis direction and the Z-axis direction are orthogonal.

[0011] Note that "left and right," "front and back," "up and down," "left side," "right side," "front side," "back side," "upper side," and "lower side" are terms used to describe the relative positional relationships of the respective parts. The actual arrangement relationship or the like may be different from the arrangement relationship or the like indicated by these terms.

[0012] As shown in FIGS. 1 and 2, a door 101 is arranged on the front side (-Y direction side) of the cooking heater 1 and below the operation panel 14 (-Z direction side). The door 101 is a door 101 for opening and closing the heating chamber 201. The heating chamber 201 includes an accommodation space 202, and an object to be heated can be placed therein. The heating chamber 201 is provided inside the cooking heater 1 and on the back side (+Y direction side) of the closed door 101. In the example of FIG. 2, the accommodation space 202 is a rectangular parallelepiped-shaped space. The object to be heated is, for example, food or ingredients.

[0013] The door 101 is openable and closable. A rotating shaft is provided on the left side (-X direction side) of the front surface of the cooking heater 1. The rotating shaft is invisible in FIGS. 1 and 2. The rotating shaft extends in the Z-axis direction. For opening and closing, a handle 102 is provided on the door 101. When the door 101 is in the closed state, the door 101 covers the front opening of the heating chamber 201. Thereby, the heating chamber 201 and the storage space are closed. When the door 101 is opened, the front opening of the heating chamber 201 is exposed. The object to be heated can be taken in and out of the storage space. FIGS. 1 and 2 illustrate a door 101 that opens horizontally by pulling it in the +X direction side. Note that the door 101 may be of a type that opens horizontally by pulling it in the -X direction side. Also, the door 101 may be of a type in which the rotating shaft is parallel to the X-axis direction and is pulled forward and falls down to open vertically.

[0014] And, as shown in FIG. 3, the cooking heater 1 includes a control unit 11, a memory 12, an open / close detection sensor 13, an operation panel 14, a heating unit 15, a reader 40, an interlocking device 50, and a wireless communication unit 16.

[0015] The control unit 11 includes a control circuit 11a. The control circuit 11a may be a CPU (Central Processing Unit) or an MPU (Micro Processor Unit). Also, for example, the cooking heater 1 includes a memory 12 such as a RAM and a flash ROM. The control circuit 11a executes the program stored in the memory 12 and operates as the control unit 11. Further, the control circuit 11a receives detection information from each sensor and performs various controls.

[0016] As shown in FIG. 3, the control unit 11 includes a connection execution unit 11b, a registration execution unit 11c, and a heating restriction unit 11d. The processes performed by the connection execution unit 11b, the registration execution unit 11c, and the heating restriction unit 11d will be described later. And the connection execution unit 11b, the registration execution unit 11c, and the heating restriction unit 11d are functionally realized by the control circuit 11a executing the program stored in the memory 12. Note that the control unit 11 may include a circuit that performs the process of the connection execution unit 11b, may include a circuit that performs the process of the registration execution unit 11c, or may include a circuit that performs the process of the heating restriction unit 11d.

[0017] The operation panel 14 receives the setting operations of the user. As shown in FIGS. 1 and 2, the operation panel 14 is provided on the front side (-Y direction side) and the upper side (+Z direction side) of the cooking heater 1. The operation panel 14 includes a plurality of setting buttons 14a. By operating the setting buttons 14a, the cooking heater 1 can be set. For example, the heating time and the output wattage of heating can be set. Also, the operation panel 14 includes a display panel 14b. For example, the display panel 14b is a liquid crystal display panel or an organic EL display panel. The control unit 11 controls the display on the display panel 14b.

[0018] In addition, the operation panel 14 is provided with a reading control button 14c for switching the reader 40 on and off. When the reader 40 is not operating and the reading control button 14c is operated (pressed), the control unit 11 starts the operation of the reader 40. When the reader 40 is operating and the reading control button 14c is operated, the control unit 11 stops the operation of the reader 40.

[0019] The opening / closing detection sensor 13 is a sensor that detects whether the door 101 is open or closed. For example, the opening / closing detection sensor 13 may be a push switch. For example, the opening / closing detection sensor 13 is movable in the Y-axis direction and has a protrusion biased in the -Y direction. When the door 101 is closed, the protrusion is pushed into the door 101, and the opening / closing detection sensor 13 outputs a first level. When the door 101 is opened, the protrusion protrudes, and the opening / closing detection sensor 13 outputs a second level. Of the high level and the low level, the first level is one of them, and the second level is the other. Then, the output of the opening / closing detection sensor 13 is input to the control unit 11. Based on the output of the opening / closing detection sensor 13, the control unit 11 recognizes (detects) whether the door 101 is open or not. Note that the opening / closing detection sensor 13 is not limited to a push switch. The opening / closing detection sensor 13 may be any sensor whose output level changes according to the opening and closing of the door 101.

[0020] The heating unit 15 heats the food placed in the heating chamber 201. For example, the heating unit 15 includes a microwave output device. The microwave output device is, for example, a magnetron. That is, the heating unit 15 heats the object to be heated by electromagnetic waves. In addition, the heating unit 15 may include a heater that generates superheated steam of 100 degrees Celsius or more and a blower that sends the superheated steam to the object to be heated.

[0021] The wireless communication unit 16 communicates with an access point (base station). In this description, a wireless communication device that functions as an access point is referred to as a wireless base device 6. The wireless communication unit 16 and the wireless base device 6 perform wireless communication in accordance with, for example, the IEEE802.11 standard (wireless LAN standard). For example, the wireless communication unit 16 includes a communication control circuit, a communication memory, and an antenna for performing wireless LAN communication.

[0022] On the other hand, the wireless base device 6 includes a communication control circuit, a communication memory, and an antenna. The wireless base device 6 is, for example, a wireless LAN router. Also, the wireless base device 6 may be a repeater connected to a router. The wireless base device 6 is connected to a wide area network 7 such as the Internet, either by wire or wirelessly. The wireless communication unit 16 can be connected to the network 7 via the wireless base device 6. The wireless communication unit 16 can access the network 7 via the wireless base device 6 and communicate with the server 8. The wireless communication unit 16 can download data from the server 8. Also, the wireless communication unit 16 can upload data to the server 8.

[0023] For example, the server 8 includes a server processing unit 81, a server storage unit 82, and a server communication unit 83. The server processing unit 81 includes a processor. The server storage unit 82 is a large-capacity storage device (storage). The server storage unit 82 may be either an HDD (Hard Disc Drive) or an SSD (Solid State Drive), or both. For example, the server storage unit 82 may store a plurality of cooking menu data of the heating cooker 1. The cooking menu data is data that defines setting values of setting items related to heating cooking. For example, the cooking menu data of a stewed dish defines setting values related to heating so that a stewed dish can be completed when executed.

[0024] For example, the server communication unit 83 includes a communication control circuit, a communication memory, and a communication interface. The server communication unit 83 communicates with the heating cooker 1 via the network 7 and the wireless base device 6.

[0025] (Reader 40) Next, an example of the reader 40 will be described with reference to FIG. 4. FIG. 4 is a diagram showing an example of the reader 40 according to the embodiment.

[0026] For example, the reader 40 is a module in which a plurality of circuits and a plurality of members are combined. For example, the reader 40 includes a processing circuit 41, a reader memory 42, an imaging unit 43, a lamp 44, and a communication interface 45. And the reader 40 is compatible with reading two-dimensional codes. For example, the reader 40 is compatible with reading QR codes (registered trademarks). Also, the reader 40 may be compatible with reading two-dimensional codes other than QR codes. That is, the code may be a QR code or a two-dimensional code other than a QR code. Also, the reader 40 may be compatible with reading barcodes (one-dimensional codes). That is, the code may be a barcode.

[0027] The processing circuit 41 may be a CPU (Central Processing Unit) or an MPU (Micro Processor Unit). The processing circuit 41 controls the operations of the reader memory 42, the imaging unit 43, the lamp 44, and the communication interface 45. The reader 40 may include a RAM and a flash ROM as the reader memory 42.

[0028] The imaging unit 43 reads the code whose information has been converted. For example, the imaging unit 43 is a camera that reads the code. The imaging unit 43 includes, for example, an image sensor 46 and an image signal processing circuit 47. Further, the imaging unit 43 may include a lens that causes light to enter the image sensor 46. The image sensor 46 includes a plurality of photoelectric conversion elements. The image sensor 46 is a two-dimensional image sensor in which the photoelectric conversion elements are arranged two-dimensionally. The image sensor 46 can image an area. The image signal processing circuit 47 processes the analog image signal output from the photoelectric conversion elements. For example, the image signal processing circuit 47 performs analog-to-digital conversion on the analog image signal to generate image data. When the reader 40 is in the on state, the processing circuit 41 causes the imaging unit 43 to perform imaging at a predetermined period. The image signal processing circuit 47 generates one page of image data of the area at a predetermined period.

[0029] Note that the processing circuit 41 may cause the generated image data to be displayed on the display panel 14b. In this case, the processing circuit 41 sends the generated image data to the control unit 11. The control unit 11 causes the display panel 14b to perform display based on the received image data. That is, the heating cooker 1 may include a display panel 14b that displays an image based on the image data obtained based on the reading by the imaging unit 43. Thereby, the imaging content of the imaging unit 43 can be displayed on the display panel 14b. The user can visually recognize the imaging content.

[0030] The processing circuit 41 analyzes the generated image data to determine whether it contains a code. For example, the processing circuit 41 determines whether the image data contains symbols (position detection pattern, finder pattern) defined in the code standard. When it contains symbols, the processing circuit 41 recognizes that the image data contains a code. Also, the processing circuit 41 recognizes the area of the code in the image data. Then, based on the dot pattern of the recognized code area, the processing circuit 41 decodes it. The reader memory 42 stores the decoding program 48 non-volatilely. Based on the decoding program 48, the processing circuit 41 decodes the code. Thereby, the information converted into the code is decoded. The processing circuit 41 obtains the information embedded in the code. The processing circuit 41 transmits the decoded information to the control unit 11 (control circuit 11a).

[0031] The memory 12 stores the setting value (current setting value) of the cooking to be executed next. For example, when the decoded information includes the value of the heating time, the control unit 11 sets the setting value of the heating time to the value of the heating time obtained by decoding. Also, when the decoded information includes the value of the output watt of the microwave output device, the control unit 11 sets the setting value of the heating output to the value of the output watt of the decoded information. Also, when the decoded information includes the value of the heating temperature, the control unit 11 sets the setting value of the heating temperature to the value of the heating temperature of the decoded information. The control unit 11 changes the current setting value in the memory 12 to the setting value described in the decoded information. The stored content of the memory 12 can be automatically changed. That is, just by having the code read, the setting value of the cooking can be set.

[0032] For example, a QR code obtained by converting the recommended values of the heating time and the output watt value may be described on the packaging of the frozen food. Just by reading the QR code on the packaging, the heating time and the output watt value suitable for cooking the frozen food can be set without operating the operation panel 14.

[0033] Note that the reader 40 may include a notification unit. For example, the notification unit may be either one or both of a light-emitting element and a speaker. For example, the light-emitting element is an LED. When it is recognized that the code has been read and the information of the code has been decoded, the processing circuit 41 may turn on the light-emitting element of the notification unit for a predetermined time. Also, when it is recognized that the code has been read and the information of the code has been decoded, the processing circuit 41 may cause the speaker to reproduce a predetermined notification sound.

[0034] The lamp 44 emits light when energized. For example, the lamp 44 is an LED. The lamp 44 may be a light-emitting element other than an LED. The processing circuit 41 controls the lighting and extinguishing of the lamp 44. The lamp 44 illuminates the imaging range of the imaging unit 43. Light emitted from the lamp 44 and reflected by the object to be imaged enters the imaging unit 43.

[0035] The communication interface 45 includes a circuit for communicating with the control unit 11 (control circuit 11a). When the read control button 14c is operated to start the operation of the reader 40, the control circuit 11a instructs the start of reading. The communication interface 45 receives this instruction. Based on this instruction, the processing circuit 41 causes the imaging unit 43 to start imaging and starts processing the image data. When the read control button 14c is operated to stop the operation of the reader 40, the control circuit 11a instructs the stop of reading. The communication interface 45 receives this instruction. Based on this instruction, the processing circuit 41 stops the imaging operation of the imaging unit 43.

[0036] As shown in FIGS. 1 and 2, the reader 40 is provided on the front surface of the cooking heater 1. The reader 40 may include a case in the shape of a cube or a rectangular parallelepiped. When the door 101 is opened, the -Y-direction surface (front surface) and the -Z-direction surface (bottom surface) of the reader 40 (case) are exposed to the outside. When the door 101 is closed, only the -Y-direction surface of the reader 40 is exposed to the outside. And the processing circuit 41, the reader memory 42, the imaging unit 43, the lamp 44, and the communication interface 45 may be housed in the case. In this case, a hole for allowing light to enter the light receiving surface of the image sensor 46 may be provided in the case. Also, a part of the lamp 44 may be exposed from the case to emit light.

[0037] (Interlocking device 50) Next, an example of the interlocking device 50 will be described with reference to FIGS. 5 and 6. FIG. 5 is a diagram showing an example of the interlocking device 50 according to the embodiment. FIG. 6 is a diagram showing an example of the rotation process of the imaging unit 43 according to the embodiment.

[0038] The interlocking device 50 rotates the reader 40. That is, the interlocking device 50 rotates the imaging unit 43. For example, the interlocking device 50 includes a motor 51 and a gear (not shown) for transmitting drive. And an imaging rotation shaft 52 is attached to the imaging unit 43. The imaging rotation shaft 52 extends in the X-axis direction (left-right direction). The motor 51 rotates the imaging rotation shaft 52. Due to the rotation of the motor 51 and the imaging rotation shaft 52, the reader 40 rotates in the circumferential direction with respect to the axial direction of the imaging rotation shaft 52. That is, the imaging direction of the imaging unit 43 is variable. The imaging range and the imaging direction of the imaging unit 43 can be moved. Since the imaging range and the imaging direction are not fixed, the imaging range and the imaging direction can be changed so as to easily read the code.

[0039] Specifically, when the door 101 is open, the control unit 11 rotates the imaging unit 43 to the interlocking device 50 so that the imaging direction is downward rather than when the door 101 is closed. When the door 101 is closed, the control unit 11 rotates the imaging unit 43 to the interlocking device 50 so that the imaging direction is upward rather than when the door 101 is open. Thereby, when the door 101 is closed and a code is held over the upward-facing imaging unit 43, the code is read. For example, when reading a code that has no relation to heat cooking, the code can be read without opening the door 101.

[0040] On the other hand, when the door 101 is open, the imaging range and the imaging direction can be downward. Thereby, when a code is positioned below the reader 40, the imaging unit 43 reads the code. It becomes easier to read the code attached to the object to be heated placed in the storage space. The imaging unit 43 can be automatically rotated according to the open / closed state of the door 101. That is, the angle of the imaging unit 43 can be automatically adjusted to an angle at which the code can be easily read.

[0041] An example of the rotation process of the imaging unit 43 will be described with reference to FIG. 6. The start of FIG. 6 is the point in time when the operation of the reader 40 is started by operating the reading control button 14c. The process of FIG. 6 continues until the operation of the reader 40 is stopped by operating the reading control button 14c. First, in step S601, based on the output of the open / close detection sensor 13, the control unit 11 checks whether the door 101 is open.

[0042] When the door 101 is open, in step S602, the control unit 11 rotates the imaging unit 43 to the interlocking device 50 and sets the imaging range and the imaging direction of the imaging unit 43 downward (-Z direction). The imaging unit 43 assumes a posture (angle) that makes it easy to image the object to be heated placed in the heating chamber 201. Then, in step S603, the control unit 11 starts lighting the lamp 44.

[0043] After step S603, in step S604, based on the output of the opening / closing detection sensor 13, the control unit 11 checks whether the door 101 has been closed. While the door 101 is open, the control unit 11 continues to check for the closing of the door 101.

[0044] When the door 101 is closed in step S601 or when the door 101 is closed in step S604, the control unit 11 performs step S605. In step S605, the control unit 11 sets the light quantity level of the lamp 44 to the level when the door 101 is closed. When the door 101 is closed, the control unit 11 reduces the light quantity of the lamp 44 compared to when the door 101 is open. In this case, the control unit 11 may instruct the processing circuit 41 to turn off the lamp 44. Based on this instruction, the processing circuit 41 turns off the lamp 44. Alternatively, the control unit 11 may give an instruction to the processing circuit 41 to reduce the light quantity to a non-dazzling level.

[0045] Then, in step S606, the control unit 11 rotates the imaging unit 43 to the interlocking device 50, and sets the imaging range and imaging direction of the imaging unit 43 to the forward direction (-Y direction). For example, the imaging unit 43 assumes a posture (angle) of imaging an object held over the front side of the cooking heater 1.

[0046] That is, the cooking heater 1 includes a lamp 44 that irradiates light toward the imaging range of the imaging unit 43 when the door 101 is open. When the door 101 is closed, the lamp 44 reduces the light it irradiates compared to when the door 101 is open. Thereby, when the imaging range and imaging direction face the front side, the light quantity of the lamp 44 can be reduced. It is possible to prevent strong light from entering the user's eyes. The light quantity of the lamp 44 is automatically adjusted so as not to be dazzling. On the other hand, when irradiating light toward the lower side (-Z direction side) of the cooking heater 1, the light quantity of the lamp 44 automatically increases. Since it faces the lower side, even if the light quantity is increased, the user will not be dazzled. Also, even if the inside of the heating chamber 201 is dark, it is possible to image an imaging object that is brightly illuminated. That is, it is possible to illuminate the imaging object so that the code can be imaged.

[0047]

[0047] In step S607, based on the output of the opening / closing detection sensor 13, the control unit 11 checks whether the door 101 has been opened. While the door 101 remains closed, the control unit 11 continues to check for the opening of the door 101. When the door 101 is opened, the control unit 11 performs step S602.

[0048]

[0047] In the cooking heater 1, the imaging unit 43 is disposed in front of the cooking heater 1 and above the accommodation space 202. When the door 101 is open, the interlocking device 50 rotates the imaging unit 43 to a position where the imaging unit 43 images the lower surface of the inner wall surface of the heating chamber 201. On the other hand, when the door 101 is closed, the interlocking device 50 rotates the imaging unit 43 to a position where the imaging unit 43 images in a direction parallel to the front-rear direction of the cooking heater 1 and from the back to the front. Thereby, when the door 101 is closed, the imaging unit 43 can be fixed at an angle for imaging the cord (subject) on the front surface of the cooking heater 1. Also, when the door 101 is open, the imaging unit 43 can be fixed at an angle for imaging the object to be heated in the heating chamber 201.

[0049] (Settings for Communication Based on a Cord)

[0047] Next, with reference to FIG. 7, an example of settings for communication based on a cord will be described. FIG. 7 is a diagram showing an example of settings for communication based on a cord in the cooking heater 1 according to the embodiment.

[0050]

[0047] By receiving authentication of the wireless base station device 6, the connection between the wireless communication unit 16 and the wireless base station device 6 can be established. By establishing a connection with the wireless base station device 6, the wireless communication unit 16 can be connected to the network 7. A plurality of pieces of information are required for connection establishment. Hereinafter, the information for receiving authentication of the wireless base station device 6 and establishing a connection will be referred to as connection setting information i1. The connection setting information i1 includes, for example, the identification name (ID information) of the wireless base station device 6 and the password (network key). For example, the identification name is the SSID.

[0051] By establishing a connection with the wireless base station device 6 and connecting to the network 7, the wireless communication unit 16 can transmit and receive data with the server 8. For example, the wireless communication unit 16 can obtain cooking menu data from the server 8. Also, the wireless communication unit 16 can transmit information regarding the maintenance of the heating cooker 1 to the server 8. The information regarding maintenance is, for example, the operating time of the heating cooker 1.

[0052] The server 8 provides various services. It is necessary to grasp and manage the devices that receive the services. Therefore, in order to receive the services, it is necessary to register the devices with the server 8. When the registration with the server 8 is completed, the wireless communication unit 16 can obtain the data stored in the server 8. Also, the server 8 stores and accumulates the information regarding maintenance transmitted from the registered devices.

[0053] Hereinafter, the information for registering the heating cooker 1 with the server 8 is referred to as device registration information i2. The device registration information i2 is, for example, the address and password of the server 8. The device registration information i2 may include other information for accessing the server 8.

[0054] By the reader 40 reading the code obtained by converting the connection setting information i1, the connection between the heating cooker 1 and the wireless base station device 6 can be established. Also, by the reader 40 reading the code obtained by converting the device registration information i2, the heating cooker 1 can be registered with the server 8.

[0055] The code to be read by the reader 40 is prepared in advance. The reader 40 may read the code displayed on the display device. The display device may be a device capable of wireless communication and having a display and an input device. For example, the display device is a smartphone, a tablet computer, or a notebook PC. The input device is, for example, a touch panel or a keyboard. Also, the code may be printed in advance. The reader 40 may read the code printed on paper.

[0056] Both the connection setting information i1 and the device registration information i2 may be collectively converted to generate one code. Alternatively, the code obtained by converting the connection setting information i1 and the code obtained by converting the device registration information i2 may be prepared separately.

[0057] (1) When combining both the connection setting information i1 and the device registration information i2 The code obtained by combining both pieces of information may be displayed on the display device. For example, the user establishes communication between the display device and the wireless base station device 6 that connects to the cooking heater 1. By this establishment, the display device collects and recognizes the connection setting information i1. Further, the user causes the display device to access the server 8 that registers the cooking heater 1. By this access, the display device collects and recognizes the device registration information i2. The input device receives an instruction to generate a code. Note that the display device may store a code creation application. When this instruction is given, the display device generates a code obtained by converting the connection setting information i1 and the device registration information i2. The display device causes the generated code to be displayed on the display. The reader 40 may read the displayed code.

[0058] Also, the user may use an information processing device to edit both the connection setting information i1 and the device registration information i2. For example, the information processing device is a PC. And the information processing device may store a code creation application. The information processing device generates a code obtained by converting the edited information. The information processing device causes the generated code to be printed by a printing device. The reader 40 may read the printed code.

[0059] (2) When preparing separately the code obtained by converting the connection setting information i1 and the code obtained by converting the device registration information i2 For example, when displaying a code containing only connection setting information i1 on a display device, the user establishes communication between the wireless base station device 6 for connecting the cooking appliance 1 and the display device. By this establishment, the display device collects and recognizes the connection setting information i1. Then, when the input device receives an instruction to generate a code for the connection setting information i1, the display device generates a code obtained by converting the connection setting information i1. The display device causes the generated code to be displayed on the display. The reader 40 may read the displayed code of the connection setting information i1.

[0060] Also, when displaying a code containing only device registration information i2 on a display device, the user causes the display device to access the server 8 for registering the cooking appliance 1. By this access, the display device collects and recognizes the device registration information i2. Then, when the input device receives an instruction to generate a code for the device registration information i2, the display device generates a code obtained by converting the device registration information i2. The display device causes the generated code to be displayed on the display. The reader 40 may read the displayed code of the device registration information i2.

[0061] Also, the wireless base station device 6 may be attached with a printed matter of a code obtained by converting connection setting information i1 such as an SSID and a password. For example, a QR code sticker may be attached. The reader 40 may read the printed matter of the code. Also, when the display device is provided with a camera, the printed matter of the code attached to the wireless base station device 6 may be photographed, and the image of the code obtained by the photographing may be displayed on the display device. Then, the reader 40 may read the photographed code displayed by the display device. Even in this way, the cooking appliance 1 can acquire the connection setting information i1.

[0062] Also, a printed matter of a code obtained by converting the device registration information i2 may be attached to the cooking appliance 1. Alternatively, a code obtained by converting the device registration information i2 may be printed on the instruction manual or the packing box of the cooking appliance 1. Then, the reader 40 may read the printed matter of the code of the device registration information i2. Even in this way, the cooking appliance 1 can acquire the device registration information i2.

[0063] The example of the method for preparing the codes of the connection setting information i1 and the device registration information i2 has been described above. The method for preparing the codes of each information is not limited to the above. The codes of each information may be prepared by other methods.

[0064] Next, an example of the process of wireless communication setting will be described with reference to FIG. 7. Before the start of FIG. 7, the operation of the reader 40 has started. And the reader 40 (imaging unit 43) is reading the held code. And the start of FIG. 7 is the point in time when the control unit 11 recognizes that the information obtained by decoding the code includes the connection setting information i1.

[0065] First, in step S701, when establishing a connection with the wireless base station device 6 based on the connection setting information i1 included in the code, the heating restriction unit 11d does not allow the heating unit 15 to heat. Although the details will be described later, when registering the device to the server 8 following the connection establishment, the heating restriction unit 11d does not allow the heating unit 15 to heat until the device registration to the server 8 is completed. That is, during the processing of the flowchart in FIG. 7, the heating restriction unit 11d prohibits heating and does not operate the heating unit 15. Specifically, even if the heating start instruction button (start button) among the setting buttons 14a of the operation panel 14 is operated, the heating restriction unit 11d does not start heating the heating unit 15. The electromagnetic wave from the heating unit 15 may interfere with the communication between the wireless communication unit 16 and the wireless base station device 6. By prohibiting the operation of the heating unit 15, it is possible to reduce the factors that interfere with the connection establishment and device registration. When the connection is established or when the device registration to the server 8 is completed, the heating restriction unit 11d releases the heating restriction of the heating unit 15.

[0066] In step S702, the connection execution unit 11b causes the wireless communication unit 16 to start communication with the wireless base station device 6. Specifically, the connection execution unit 11b causes the wireless communication unit 16 to transmit a connection establishment request to the wireless base station device 6 with the SSID (identification name) included in the connection setting information i1.

[0067] Next, in step S703, the connection execution unit 11b causes the wireless communication unit 16 to transmit and receive information for establishing a connection with the wireless base station device 6. For example, the connection execution unit 11b causes the wireless communication unit 16 to transmit the password included in the connection setting information i1 and the MAC address of the wireless communication unit 16. In this way, when the code read by the reader 40 includes the connection setting information i1, the connection execution unit 11b causes the wireless communication unit 16 to communicate with the wireless base station device 6 as an access point, and establishes a connection between the wireless communication unit 16 and the wireless base station device 6 based on the connection setting information i1. Thereby, the connection setting of the wireless communication can be performed only by reading the code. Here, the portable communication device is not necessarily required for the connection setting of the wireless communication of the cooking heater 1. Even a person who is not good at operating the portable communication device or manual input can easily perform the connection setting of the wireless communication of the cooking heater 1.

[0068] As a result of the communication, in step S704, the wireless base station device 6 determines whether it is possible to authenticate the wireless communication unit 16. That is, the wireless base station device 6 determines whether communication can be established. For example, when there is no problem with all of the information transmitted and received by the wireless communication unit 16, the wireless base station device 6 may determine that the wireless communication unit 16 is authenticated. Also, for example, when the password transmitted by the wireless communication unit 16 is incorrect, the wireless base station device 6 may determine that the wireless communication unit 16 is not authenticated.

[0069] When it is determined not to authenticate, in step S705, the wireless base station device 6 notifies the wireless communication unit 16 that it does not authenticate. Since the authentication and the establishment of the communication have failed, the control unit 11 (connection execution unit 11b) ends the processing of this flowchart (END).

[0070] On the other hand, when it is determined that the wireless communication unit 16 is authenticated, in step S706, the wireless base station device 6 notifies the wireless communication unit 16 of the authentication. Communication is established between the wireless communication unit 16 and the wireless base station device 6. Upon receiving this notification, in step S707, the control unit 11 causes the connection setting information i1 to be non-volatilely stored in the memory 12. In subsequent communications, the wireless communication unit 16 communicates with the wireless base station device 6 using the stored connection setting information i1. Thereafter, the wireless communication unit 16 can freely access the network 7 and the server 8 via the wireless base station device 6 using the connection setting information i1.

[0071] Next, in step S708, the registration execution unit 11c checks whether the device registration information i2 is included in the information obtained by decrypting the code. When the device registration information i2 is not included, in step S709, the registration execution unit 11c checks whether a code obtained by converting the device registration information i2 is read within a predetermined waiting time. Consider the case where the code of the connection setting information i1 and the code of the device registration information i2 are different. The predetermined waiting time is determined as appropriate. For example, the predetermined waiting time is several minutes. If the code obtained by converting the device registration information i2 cannot be read during the predetermined waiting time, the control unit 11 (registration execution unit 11c) ends this flowchart (END).

[0072] On the other hand, when the information obtained by decrypting the code includes the device registration information i2, or when the code obtained by converting the device registration information i2 is read, in step S710, the registration execution unit 11c executes device registration to the server 8 based on the device registration information i2. Specifically, based on the address information of the device registration information i2, the registration execution unit 11c causes the wireless communication unit 16 to access the server 8 via the wireless base station device 6. Also, for device registration, the registration execution unit 11c may cause the wireless communication unit 16 to transmit the model name and unique information of the cooking heater 1. The unique information may be the manufacturing number or other information.

[0073] Based on the information transmitted from the wireless communication unit 16, the server 8 registers the cooking heater 1. The server 8 transmits the completion of registration to the wireless communication unit 16. In step S711, the wireless communication unit 16 receives the completion of registration. Note that the server 8 may also transmit the management number of the cooking heater 1. When receiving the completion of registration, the control unit 11 may non-volatilely store the device registration information i2 and the management number in the memory 12. When accessing the server 8 and transmitting and receiving data, the control unit 11 may communicate using the device registration information i2 and the management number.

[0074] Note that when the device registration information i2 is inappropriate, the server 8 may not approve the registration of the device. At this time, the server 8 notifies the wireless communication unit 16 of a message indicating that the device cannot be registered. When receiving the message indicating that registration is not possible, the control unit 11 may end this flowchart without executing step S711. Alternatively, the registration execution unit 11c may execute step S709.

[0075] As described above, when the code read by the reader 40 includes the device registration information i2 for registering the cooking heater 1 with the server 8, the registration execution unit 11c causes the wireless communication unit 16 to communicate with the server 8 via the wireless base station device 6 and executes the device registration with the server 8 based on the device registration information i2. Thereby, the cooking heater 1 can be registered with the server 8 simply by reading the code. A mobile communication device is not necessarily required for the registration procedure of the cooking heater 1 with the server 8. Even a person who is not good at operating a mobile communication device or manual input can easily register the cooking heater 1 with the server 8.

[0076] (Installation of the mirror 103) Next, an example of the installation of the mirror 103 will be described with reference to FIGS. 1 and 2. By holding the code in front of the reader 40, the code is read. If the entire code does not fit within the imaging range, the code cannot be recognized. Also, if the focus is not adjusted properly, it may not be possible to recognize that the code has been read. If it is not recognized that the code has been read, the user moves the object with the code closer to or farther from the imaging unit 43. Also, the user may move the object with the code up, down, left, or right.

[0077] However, it may be difficult to determine whether the position of the code is appropriate with respect to the imaging unit 43. Therefore, as shown in FIGS. 1 and 2, a mirror 103 may be provided near the reader 40. FIGS. 1 and 2 show an example in which the mirror 103 is provided above the reader 40 when viewed from the front direction of the cooking heater 1.

[0078] The mirror 103 reflects the view in the front side (-Y direction) of the cooking heater 1. The mirror 103 may be installed such that the plane (mirror surface) is perpendicular to the imaging direction of the imaging unit 43. The position of the code held in front of the reader 40 (imaging unit 43) can be confirmed by the mirror 103. Further, a frame line 104 indicating the imaging range (the range in which the code should be contained) of the imaging unit 43 may be marked on the mirror 103. In this way, the cooking heater 1 may include a mirror 103 on which a frame line 104 indicating the range in which the code is contained is marked, and which reflects the code held in front of the imaging unit 43. Thereby, it is possible to visually confirm whether the entire code is within the imaging range of the imaging unit 43. It becomes easier to confirm whether the code is held so as to be recognized.
