Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker such as a microwave oven, a microwave oven, a rice cooker, and an electromagnetic cooker, which controls heating based on cooking information obtained from the outside through a network such as the Internet.

[0002]

2. Description of the Related Art A system for obtaining cooking information necessary for a heating cooker through a network such as the Internet
It is proposed in Japanese Unexamined Patent Publication No. 2001-3336752.
Here, the cooking information such as the heating method, heating time and control temperature required for cooking is established by connecting to the outside network via the wireless wide area network of the mobile phone directly connected to the cooking device by a cable. Get from an external server. Further, the obtained cooking information is stored in the non-volatile memory, and the once-obtained cooking information can be called from the non-volatile memory and used at any time.

[0003]

In the above system,
The cooking information is acquired through the network outside the home only when the acquisition operation is executed for the first time, and in other cases, the cooking information is acquired from the nonvolatile memory.

That is, when the cooking information is called for the first time, the cooking information is downloaded from the homepage which provides the cooking information by connecting to the Internet. For subsequent calls, cooking information is always read from the non-volatile memory. Therefore, when the content of the cooking information is updated, it cannot be reflected in the cooking control unless the server is accessed to obtain the latest cooking information.

Even if the stored cooking information can be selected and erased so that the cooking information is updated, it is necessary for the user side to manage whether or not the cooking information is updated. In this case, management becomes difficult when the number of stored cooking information increases.

In order to solve this, if the cooking information is searched for whether it is updated through the network outside the house in response to calling the cooking information, the latest cooking information can always be obtained. However, in the heating cooker, the access process to the network side is always performed, and therefore, it is necessary to connect to the network each time a call is made, it takes time, and the response to the acquisition operation becomes poor. Furthermore, the storage of cooking information in the non-volatile memory becomes meaningless.

In view of the above, the present invention has taken advantage of the environment in which information can be acquired through a network, and constantly improves the response to the operation for acquiring cooking information while always acquiring the latest cooking information. The purpose is to provide a cooking device.

[0008]

According to the present invention, there is provided a communication means for communicating with an external information device connected to a network, and heating based on cooking information acquired from the external information device. With a control unit that controls cooking,
The communication unit accesses the external information device to acquire the cooking information from the external information device, a storage unit that stores the acquired cooking information, and a network device that is connected to the external information device from the external information device. And a selection unit for selecting whether to acquire the cooking information or to read and acquire the cooking information from the storage unit.

According to this, during the connection to the network, the acquisition from the external information device is preferentially selected to acquire the latest cooking information. When it is not necessary to obtain the requested cooking information from the external information device, for example, when the latest cooking information is already stored in the storage unit, the cooking information is read from the storage unit. Therefore, the required cooking information can be quickly acquired without performing communication with the external information device, and the response of the acquisition operation can be improved.

The selection of whether to obtain from the external information device or from the storage means is made by judging whether or not the latest cooking information is stored in the storage means. If the cooking information stored in the storage means is not the latest, acquisition from the external information device is selected.

Here, the communication section has an updating means for deleting the cooking information stored in the storage means when the cooking information is acquired from the external information equipment. That is, when there is an acquisition request, old cooking information is erased and updated to the latest cooking information acquired from the external information device. Also,
As another criterion for selection, information indicating that the information is the latest cooking information or information indicating that the cooking information is old is added to the acquired cooking information and stored in the storage means. You may make a decision based on this information.

The selection means selects acquisition from the storage means when the requested cooking information is already stored in the storage means, and selects acquisition from the external information device when the requested cooking information is not stored in the storage means. The fact that the requested cooking information is already stored in the storage means means that the latest cooking information has been acquired from the external information device, and if the same cooking information is requested, it will be acquired from the external information device. Even if it is not necessary, the necessary cooking information can be immediately acquired by reading it from the storage means.

Further, the selecting means selects acquisition from the external information device when the external information device is accessed for the first time after connecting to the network. In this way, when the external information device is accessed for the first time, the storage means stores the previously acquired cooking information, that is, the old cooking information.
Since the external information device may have been updated to the latest cooking information, the latest cooking information must be acquired from the external information device.

When the connection to the network is impossible, the selecting means selects acquisition from the storage means until the connection becomes possible. In such a state, it is not possible to communicate with the external information device, so that if there is an acquisition request, the cooking information can be acquired from the storage means and can be dealt with. If connection to the network becomes possible, communication with an external information device can be performed, and thus cooking information is acquired from the external information device.

The cooking information has a hierarchical structure and includes identification information for identifying each hierarchy. The updating means determines the hierarchy to which the requested cooking information belongs, and the cooking information including the identification information for this hierarchy. Erase. According to this, the minimum cooking information is erased, and it is possible to prevent the necessary cooking information from being erased. After that, the latest cooking information belonging to the deleted layer may be acquired from the external information device, and the time required for acquisition can be shortened.

At this time, the information acquisition means adds identification information to the acquired cooking information and outputs it to the storage means. Since the cooking information acquired from the external information device does not include the identification information, the identification information is added when the cooking information is acquired. Therefore, since the cooking information including this identification information is stored in the storage means, it is possible to determine the hierarchy to which the requested cooking information belongs.

Further, the information acquisition means automatically acquires the cooking information of the same level as the requested cooking information. According to this, when there is no acquisition request while connecting to the network,
Since the communication unit is in a standby state, this standby time is used to acquire other unrequested cooking information from the external information device. Therefore, when there is an acquisition request, the cooking information can be immediately read from the storage unit, the time required for acquisition can be shortened, and the time can be effectively utilized.

In the heating cooker, the cooking mode is obtained from the Internet 4 by the input from the external input switch 12 or the operation panel 13 and the cooking mode is performed based on the cooking information (hereinafter, Internet cooking mode). ) Is executed. That is, the external heating controller 9 outputs a request for acquiring desired cooking information to the network communication processing unit 2 and, based on the cooking information returned from the network communication processing unit 2, the liquid crystal display unit 8
Is a control unit that displays a screen on the screen and controls heating of the heating unit 6.

The network communication processing unit 2 is built in the heating cooker main body 1 or externally attached, and has a communication controller 15, a flash memory 16 as a rewritable and erasable nonvolatile storage medium, and a power supply circuit for driving. 17
Equipped with. The storage medium may be a rewritable and erasable non-volatile one, and may be a magnetic disk or an optical disk.

The communication controller 15 is an external heating controller 9 which enables communication by a communication cable or wirelessly.
Connected to the external heating controller 9, connected to the Internet 4 via the mobile phone 3, communicated with the data supply external device 5, and stored the acquired data in the storage medium 16. That is, the information acquisition unit that accesses the data supply external device 5 to acquire the cooking information, the storage unit that stores the acquired cooking information in the storage medium 16, and the cooking information from the data supply external device 5 while connected to the Internet 4. Selection means for selecting whether to acquire the cooking information or to read and acquire the cooking information from the storage medium 16, and when the cooking information is acquired from the data supply external device 5, the cooking information stored in the storage medium 16 is erased. And an updating means for doing so.

The data supply external device 5 is installed outside the house and holds a cooking information database 18 for holding cooking information such as cooking sequence data for heating cookers and recipe information.
And supplying the target data from the cooking information database 18 in response to a data acquisition request via the Internet 4
The eb server 19 is provided.

Here, the operation of the heating cooker will be described. When the external input switch 12 of the operation unit 7 is input,
As shown in FIG. 2A, the liquid crystal display unit 8 displays a screen for selecting a predetermined genre. When one genre is selected from these by the input from the operation panel 13, the list information of the cooking menu is further displayed as shown in FIG. 2B. Further, when one menu is selected from the listed cooking menus by the input from the operation panel 13, the cooking sequence data and recipe information of the finally desired cooking menu can be acquired.

In the flash memory 16 of the network communication processing unit 2, as shown in FIG. 2C, one block of the memory block is associated with each genre, and the head area of each memory block corresponds to the target genre. The list data of the cooking menu to which it belongs and the cooking data for each cooking menu are sequentially recorded in the subsequent areas.

Next, the processing procedure in the internet cooking mode will be described with reference to the flowchart of FIG. 3 and the sequence diagram of FIG. First, when the power switch 11 of the operation unit 7 is turned on, power is supplied to the network communication processing unit 2 via the power control unit 10. The communication controller 15 is activated to first check the connection of the mobile phone 3 (S1). Based on the result of the check, it is determined whether or not the connection is established (S2). If it is in the connected state, it waits for the cooking information acquisition request from the external heating controller 9 to be input (S3).

When the external input switch 12 is input (T1) in the cooker body 1, the mode shifts to the internet cooking mode, and the genre selection screen shown in FIG. 2 (a) is displayed on the liquid crystal display section 8. (T2). "Sweets menu" is selected from the genre list display screen (T3)
Then, the external heating controller 9 outputs a cooking information acquisition request to the communication controller 15 in order to acquire the list data of the cooking menu for the "sweets menu" genre (T4).

When the communication controller 15 detects this cooking information acquisition request (S3), it detects whether or not it is connected to the Internet 4 (S4). At this time, since the connection state to the Internet 4 is not yet established, the dial-up process is performed to the access point registered in advance (S21) to connect to the Internet 4. In the meantime, the communication controller 15 extracts from the content of the previously received cooking information acquisition request that it is a cooking menu list data acquisition request for the "sweets menu", and after the network communication processing unit 2 is activated. Recognize that this is the first acquisition request.

Then, when it is confirmed that the request is a list data acquisition request for the cooking menu and the access is the first time (S13), acquisition of cooking information through the Internet 4 is selected. After erasing the memory block in the flash memory 16 corresponding to the "sweets menu" genre (S17), the H that is the Internet protocol is sent to the Web server 19 of the data supply external device 5.
A list data acquisition request is made using TTP (T5), and target sweets menu list data is acquired (T6,
S18). The acquired result is returned to the external heating controller 9, and the same data is written in the head area of the memory block in the flash memory 16 that was erased earlier (T7, S19).

Thereafter, it is detected whether or not a predetermined time has passed while detecting whether or not there is a request for obtaining cooking information from the external heating controller 9 (S3) (S9). Waiting for the input of the acquisition request while maintaining the connection state to the Internet 4 until the predetermined time is reached, and when the predetermined time elapses (S
3), the line is disconnected (S10).

When the sweets menu list data is acquired by the external heating controller 9, the menu list data shown in FIG. 2B is displayed on the liquid crystal display unit 8 (T
8). If "chocolate cake" is continuously selected from the menu list display screen while the line is connected (T19), a cooking information acquisition request is output to obtain cooking data for "chocolate cake" (T9).

When the communication controller 15 detects the cooking information acquisition request (S3), it confirms that the request is not a list acquisition request and is not the first access (S13). It is extracted that the request is for acquisition of cooking data for "cake" (S1).
4).

It is detected whether or not "chocolate cake" is already recorded in the flash memory 16 (S1).
5). In this case, since the memory block has been erased first, "chocolate cake" is stored in the flash memory 16.
There is no cooking data related to this, and it is determined that the desired cooking data needs to be acquired from the data supply external device 5, and the acquisition from the Internet 4 is selected. An acquisition request is issued to the Web server 19 using HTTP (T
10) Obtain the target cooking data (T11, S
18), the acquired result is returned to the external heating controller 9, and the acquired data is written to the second area from the head area of the memory block in the flash memory 16 (T12, S19).

In the external heating controller 9, recipe information of "chocolate cake" is displayed on the liquid crystal display portion 8 based on the received cooking data (T13), and heating control is performed as necessary.

Then, when the line is connected, the external input switch 12 is input and the genre of "sweets menu" is selected again (T14), and in the communication controller 15, the external heating controller 9 is used. The request for obtaining the list of cooking menus for the "sweets menu" is detected (T15, S3). Since it is the second acquisition request for the requested menu list data, acquisition from the flash memory 16 is selected. Since the target sweets menu list data is recorded at the head of the memory block of the flash memory 16, the list data is read from the flash memory 16 (T16, S1).
6), the acquired result is returned to the external heating controller 9 (T17, S20).

Similarly, when the same "chocolate cake" as above is selected (T20), the communication controller 15
Then, in order to detect that it is already recorded in the flash memory 16 (S15), the target cooking data is read from the flash memory 16 (T22, S1).
6), the acquired result is returned to the external heating controller 9 (T23, S20).

As described above, after the connection to the Internet 4 is started, the acquisition request for the same data is acquired from the existing data in the flash memory 16. Therefore, the acquisition is performed by connecting to the Internet 4. It is not necessary, the time required for acquisition can be shortened, and the response to the acquisition operation improves.

If "cheese cake" is selected (T24), the communication controller 15 needs to obtain the target cooking data from the data supply external device 5 because it does not exist in the flash memory 16. A judgment is made (S15). If there is a memory block in the flash memory 16 corresponding to old cooking data, it is erased (S17)
After that, an acquisition request is made to the Web server 19 using HTTP (T26). The target cooking data is acquired from the Web server 19 (T27, S18), the acquired result is returned to the external heating controller 9, and the second and subsequent empty areas of the memory block in the flash memory 16 are returned. The cooking data is written in (T28, S19).

The communication controller 15 temporarily disconnects the dial-up line (S10) and waits if the cooking information acquisition request from the external heating controller 9 continues for a predetermined time (S9). Return to. If the "candy menu" is selected after switching to the Internet cooking mode once the line is disconnected, the same process is performed again from the process of erasing the block in the flash memory 16.

In this way, the old cooking information corresponding to the selected genre is erased at each timing when the connection processing to the Internet 4 is required, including after the power is turned on, and then the cooking information is transmitted through the Internet 4. The latest cooking information can be used by acquiring it.
Also, even if the same cooking information is requested to be obtained even in the state of being connected to the internet 4, the data is obtained from the flash memory 16 without being obtained through the internet 4, so the time required for the acquisition is reduced. It can be shortened and the response to the acquisition operation is improved.

By the way, the mobile phone 3 connected to the network communication processing unit 2 may be removed, or communication abnormality with the mobile phone 3 may occur. When such a connection to the Internet 4 is impossible, the communication controller 1
In 5, selection is made to obtain cooking information from the flash memory 16 until connection to the Internet 4 is possible.

That is, when the connection state of the mobile phone 3 is detected (S1) and it is detected that the mobile phone 3 is not in the connection state (S2), the offline mode is set (S).
5). When the offline mode is valid, even if it is detected that the cooking information acquisition request is issued from the external heating controller 9 (S3), all data acquisition from the flash memory 16 is tried (S7). If the target data for the acquisition request does not exist in the flash memory 16, error screen data notifying the user that the connection state with the mobile phone 3 is abnormal is returned to the external heating controller 9 (S11). The external heating controller 9 is
An error screen is displayed on the liquid crystal display unit 8. If the target data for the acquisition request is in the flash memory 16, it is read and returned to the external heating controller 9 (S8).

After that, when the mobile phone 3 is connected to the network communication processing unit 2 again, or when the communication abnormality with the mobile phone 3 is eliminated, it is detected again that the mobile phone 3 is in the connection state. (S2), the off-line mode is released and the normal processing is resumed.

Next, the data structure of cooking information will be described.
As shown in FIG. 5A, the data in the cooking information has a hierarchical structure, and there are "sweets menu", "menu of the month", etc. as the genre type of the highest hierarchy. There are "cakes" and "Japanese sweets" as submenus of the "sweets menu". In the lowest layer, for example, in "cakes", each cooking data such as "chocolate cake" is positioned.

Each data has a data item identification code (MID in this case) as identification information for identifying a layer.
It is set) respectively. The identification code is information associated with cooking information.

In such a data hierarchy structure, when the Internet cooking mode is executed, first, when the "candy menu" is selected from the genre selection screen, FIG.
As shown in (b), with the menu list data for the "sweets menu" acquired through the Internet 4, a high-level identification code (MID = 1) indicating which selection screen was selected is added to the flash memory. 16 are recorded. Similarly, when the submenu "cakes" is selected from the menu selection screen for the "sweets menu", the menu list data for "cakes" acquired through the Internet 4 and the upper identification code (MID = 10) is added and recorded.

Here, the flash memory 16 shown in FIG.
The memory management operation in the case where the Internet cooking mode is executed in the state where seven data as shown in (b) are already recorded will be described.

As shown in FIG. 5A, the contents of the cooking information database 18 of the data supply external device 5 are as follows.
It is assumed that the name is changed from "Apple cake" to "Coffee cake". First, when "sweets menu" is selected from the genre selection screen, MID = 1 representing the genre selection screen is extracted from the menu list data according to the content of the acquisition request. Then, erasing is performed on the data in the flash memory 16 holding the same MID = 1. In this case, the menu list data of (1) and the identification code, which is the information associated with the menu list data, is erased before the data acquisition. After obtaining the sweets menu list data from the data supply external device 5 again, MID
The sweets menu list data with = 1 added is recorded again.

When "cakes" is selected from the submenu for the "sweets menu", similar to the previous processing,
MID = 10 is extracted from the selected menu list data, and the list data of (2) holding the same MID = 10 is erased from the flash memory 16. Similarly, when "chocolate cake" is selected from the selection screen for the "cakes" submenu, MID = 11 is extracted from the selected menu list data and the same MID is extracted.
The cooking data of (3), (4), and (5) holding = 11 is erased from the flash memory 16. Instead, the newly acquired cooking data has a higher identification code (MID = 1).
It is recorded in the flash memory 16 together with 1).

At this time, since the contents of the cooking information database are changed, the data in the flash memory 16 is erased even for the cooking data of "apple cake" which is no longer selected. Therefore, it does not remain as unnecessary data in the flash memory 16. In addition, because the data is selectively erased only for the items that require data update for the selected items, the processing time related to data erase can be distributed for each operation input, and it is possible to erase the data collectively. Compared with this, the processing time can be shortened and the response to the acquisition of cooking information can be improved.

Further, the information acquisition means of the network communication processing unit 2 has a function of automatically acquiring the cooking information of the same hierarchy as the requested cooking information when there is a waiting time while connected to the Internet 4. There is. This automatic acquisition operation of cooking information will be described.

As shown in FIG. 6, when the confectionery menu list is displayed on the liquid crystal display unit 8 (T30), "cakes" is selected from the submenus for the "confectionery menu" (T31). ), The cooking request acquisition request is output from the external heating controller 9 (T32). First, the communication controller, based on the content of the acquisition request, is M, which is the identification information of the selected snack menu list data.
The list data of ID = 10 is extracted and held (T3
7). An acquisition request is made to the Web server 19 of the data supply external device 5 using HTTP (T33), and menu list data of "cakes" to be acquired is acquired (T34). The acquired result is returned to the external heating controller 9 and the acquired list data is written in the flash memory 16 (T35). A menu list of cakes is displayed on the liquid crystal display unit 8 (T36).

Continuing on, the identification information previously held
Investigate whether there is any other data having the same MID (= 10). The communication controller 15 requests the data supply external device 5 to acquire the table data indicating the menus belonging to the same layer using HTTP (T38), and W
The table data of the menus belonging to the same layer is acquired from the eb server 19 (T39). When it is detected that the "Japanese confectionery menu" exists in the same layer by referring to this table data, the HTT is again sent to the Web server 19.
A request for obtaining list data is made using P (T40), and the Japanese confectionery menu list data is obtained (T41). This list data is recorded in the flash memory 16 (T4
2).

Usually, after the communication controller 15 returns various data to the external heating controller 9, the operation on the screen displayed on the heating cooker main body 1 side is performed. During this time, the communication controller 15 waits in a state of being connected to the Internet 4, so that it is possible to try to acquire other cooking information by using this waiting time. By acquiring and storing the cooking information other than the requested cooking information in this manner, it is highly possible that necessary cooking information can be acquired from the flash memory 16 for the operation in the Internet cooking mode thereafter. Therefore, there is no need to connect to the Internet 4 to acquire, and the response from the acquisition request of cooking information to the display is improved.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention. The network communication processing unit is not limited to the system configuration in which the heating cooker body is set, and may be an appliance such as a server in which the network communication processing unit is provided independently of the heating cooker. It is possible to connect a plurality of types of heating cookers such as a microwave oven, a microwave oven, a rice cooker, and an electromagnetic cooker to the network by one network communication processing unit.

Also, the connection form to the Internet is not limited to a wireless system using a mobile phone, but a system configuration using an analog modem in the network communication processing unit and using a telephone line network, or ADS.
The system configuration may use an infrastructure environment such as L, optical fiber, CATV, and power line that is always connected. Furthermore, a system configuration may be used in which a network communication processing unit and a data supply external device are connected by a dedicated line to form a network for direct communication.

Although the data supply external device, which is an external information device, is installed outside the house, it may be installed inside the house to form a LAN network with the heating cooker. The heating cooker can acquire cooking information through the home network. Then, the data supply external device is connected to an external server through a network outside the house such as the Internet so as to always obtain and store the latest cooking information.

Instead of deleting the old information when acquiring the cooking information, the latest cooking information may be overwritten when the cooking information of the same name is acquired. At this time, data such as the acquisition date and time of the cooking information is added so that it can be identified whether the cooking information is the latest. When a cooking information acquisition request is made, this data is checked to determine whether the cooking information was acquired prior to the time of connecting to the network this time. If it is the previously obtained cooking information, it is determined that the latest information is not stored, and it is selected to obtain the cooking information through the network. If it is the latest one, select acquisition from the recording medium.

[0059]

As is apparent from the above description, according to the present invention, even when the cooking information supplied from the network side is updated, the cooking information is preferentially acquired through the network. Cooking information can be used. Further, since the same data is not acquired through the network more than necessary, the response to the cooking information acquisition operation is improved and the user is not uncomfortable.

Further, even for the cooking information stored once, it is once erased according to the timing of acquisition and then reconstructed with the latest cooking information. Therefore, the user updates the cooking information especially saved. There is no need to manage the presence or absence of the information, and it is possible to always keep the latest version without imposing a burden on the user.

By deleting the old cooking information in this way, the contents of the cooking information are updated, and unnecessary information that cannot be acquired thereafter is also deleted, and is stored in the storage medium. A finite memory capacity can be effectively utilized without continuing to exist.
