Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker for responding to a malfunction of some of a plurality of functional parts used for cooking, and an operation of the heating cooker. The present invention relates to a heating cooker information notification system having an information terminal for notifying various kinds of information.

[0002]

A cooking device such as a microwave oven is provided with various functional parts for performing cooking, and when any one of them fails, a display is displayed on the display. The operation is configured to notify the user of the failure. In that case, the cooking operation thereafter becomes impossible at the time when the failure is detected, and the user has to take measures such as repairing the failed functional part.

Therefore, for example, at the stage where the user has already prepared the food to be cooked, and if the above-mentioned failure occurs when the user tries to cook the food by the microwave oven, the prepared food is wasted. There is a risk of becoming. In such a case, it is an urgent task for the user not to repair the malfunction of the microwave oven but to do cooking of the prepared food.

The present invention has been made in view of the above circumstances, and an object thereof is to cope with a direction of performing cooking operation as much as possible even when a part of a plurality of functional parts fails. It is to provide a heating cooker capable of performing the above, and an information notification system of the heating cooker.

[0005]

In order to achieve the above object, the heating cooker according to claim 1 excludes the malfunctioning function part when any one of the plurality of function parts fails. It is characterized by comprising an emergency operation processing means for performing processing for executing the emergency operation.

That is, the function of the heating cooker is as follows:
For example, there are heating means such as a magnetron and a heater, and a sensor for detecting the state of an object to be cooked in order to automatically perform optimum cooking control. Then, for example, even if a part of the sensor fails, if the function for performing some kind of heating is normal, it is possible to perform the heating for the time being by that function. In other words, depending on the type of functional part that has failed, it may be possible to perform cooking with an alternative form. Therefore, in such a case, if the emergency operation processing means performs the processing for executing the emergency operation, even if a failure occurs, it becomes possible to perform cooking in an alternative manner. You can cook the prepared ingredients without wasting them.

In this case, as described in claim 2, the emergency operation processing means determines whether or not the emergency operation is possible when a failure occurs, and when it is determined that the emergency operation processing is possible, the emergency operation is automatically performed. It may be configured to execute. According to this structure, the user does not need to make the judgment or the operation for executing the emergency driving by himself, so that the convenience is improved.

Further, as described in claim 3, the emergency operation processing means is configured to judge whether or not the emergency operation is possible when a failure occurs, and to notify if the emergency operation is possible. You may. With this configuration, the user
When a failure occurs, it is possible to recognize from the notification that the emergency operation is possible.

Further, as described in claim 4, when a failure occurs, the emergency operation processing means determines whether or not the emergency operation is possible. When it is determined that the emergency operation is possible, the emergency operation by the user is performed. It may be configured to allow execution selection of. That is, even if the emergency driving is possible, the user may not want to perform the emergency driving different from the original driving mode. Therefore, with such a configuration, it is possible to perform the emergency driving when the execution of the emergency driving is selected based on the intention of the user.

In this case, as described in claim 5, the emergency driving processing means may be configured to automatically execute the emergency driving when the user selects execution of the emergency driving. That is, if the emergency operation is automatically executed at the time when the user's intention is confirmed, the subsequent operation procedure can be eliminated.

Further, as described in claim 6, when the user selects execution of the emergency driving, the emergency driving processing means may be configured to notify the operation procedure for executing the emergency driving. Well, with this configuration, the user can execute the emergency operation by performing the operation in accordance with the notified operation procedure.

In the above case, as described in claim 7 or 8, a plurality of detecting means for detecting the physical quantity in the heated state or the initial state of the object to be heated are provided,
The emergency operation processing means may be configured to execute the emergency operation by substituting any other detection means when any one of the plurality of detection means fails. Alternatively, the emergency operation processing means may be configured to execute the emergency operation using the other detection means when any of the plurality of detection means fails.

That is, the plurality of detecting means may be used to improve the control accuracy of the cooking by obtaining information on the state of the object to be heated from various angles. Therefore, if a failure occurs, any other detecting means is substituted (Claim 7) or any other detecting means (Claim 8) is used to perform the emergency operation, so that the control accuracy is somewhat improved. Cooking can be done without major loss, although it can be reduced.

In this case, as described in claim 9, as the detecting means, an infrared sensor for detecting the temperature of the object to be heated and a weight sensor for detecting the weight of the object to be heated are provided, and the emergency operation processing means is provided. When the infrared sensor fails, the emergency operation may be performed only on the basis of the weight detected by the weight sensor.

That is, in the control system in which the heating and cooking time is set by using both the infrared sensor and the weight sensor,
Usually, the upper and lower limits of the cooking time are set based on the weight of the object to be heated detected by the weight sensor at first, and the temperature of the object to be heated is set by the infrared sensor during the actual cooking. Determine if the temperature is reached. When the temperature of the object to be heated exceeds the lower limit of the cooking time when the temperature reaches the set temperature, the heating is finished at that time.

Therefore, if the infrared sensor fails,
Even if the emergency operation is performed only based on the weight detected by the weight sensor, the cooking will be finished when the set heating and cooking time is reached, so that the cooking can be practically performed without any problem. .

In the above case, as described in claim 10, a plurality of heating means are provided, and if any one of the plurality of heating means fails, an emergency operation is performed using the other heating means. It is good to configure like this. That is, when a plurality of heating means are provided, the heating means that is most suitable for various cooking courses according to food materials is selected. Therefore, if any of them fails, if the emergency operation is performed using the other heating means, it is possible to perform the cooking even if it is not necessarily optimum.

In this case, as described in claim 11,
By using a plurality of heating means, it is possible to perform oven cooking in which hot air is circulated for heating and oven cooking in which heating is directly performed using a heating element, and
The emergency operation processing means may be configured to perform the emergency operation by executing the other oven cooking when one of the oven cooking becomes inexecutable due to any failure of the heating means.

That is, although the heating method is slightly different between the hot air circulation type heating and the direct heating by the heating element, there is no difference in the essence of performing heating. Therefore, when one of the oven cooking cannot be performed due to the failure of the heating means, it is possible to perform the emergency operation by the other oven cooking.

An information notification system for a heating cooker according to a twelfth aspect of the present invention notifies various information related to the operation of the heating cooker by communicating between the heating cooker and the heating cooker. In the case where any one of the plurality of functional parts fails, the heating cooker has a function of excluding the defective functional part and performing emergency operation. Along with transmitting information about the failure to the information terminal, the information terminal,
Based on the transmitted information, it is determined whether or not the emergency operation is possible for the heating cooker, and if it is determined that the emergency operation is possible, the fact is notified.

That is, in the display section arranged in the main body of the cooking device, the size of the display area is limited due to the restriction of space, so that the amount of information that can be displayed is limited. In particular, it cannot be said that the information regarding the failure is displayed in a form that is easy for the user to understand.

Therefore, if an information terminal capable of communicating with the heating cooker is separately provided and the information transmitted from the heating cooker is notified by the information terminal, more information can be notified, The information about the failure can be presented in a form that is easier for the user to understand. Then, when the heating cooker is configured to be capable of emergency operation, if the information terminal informs that emergency operation is possible based on the transmitted failure information, the user notifies the fact via the information terminal. Can be easily recognized.

In this case, as described in claim 13,
When the information terminal is configured so that a user can input an operation and determines that the emergency operation is possible,
It may be configured to allow the user to select execution of the emergency operation. According to this structure, the user can select the execution of the emergency operation by operating the information terminal.

Further, in this case, as described in claim 14, when the user selects execution of the emergency operation, the information terminal is configured to cause the heating cooker to automatically execute the emergency operation. May be. That is, if the emergency operation is automatically executed at the time when the user's intention is confirmed, the subsequent operation procedure can be eliminated.

Further, according to a fifteenth aspect, the information terminal is configured to notify an operating procedure for causing the cooking device to execute the emergency operation when the user selects execution of the emergency operation. You may. With this configuration,
The user can execute the emergency operation by performing the operation in accordance with the notified operation procedure.

In the above case, as described in claim 16, the program for executing the emergency operation may be arranged on the heating cooker side. Further, as described in claim 17, the program may be arranged on the information terminal side, and the heating cooker may receive the program from the information terminal and execute the program. According to this structure, the heating cooker does not need to have the program in the internal ROM in advance, so that the capacity of the ROM can be reduced.

Further, as described in claim 18, in order to execute the emergency operation by configuring the information terminal so as to be able to communicate with a server connected to an external communication network. The program may be received from the server, and the heating cooker may be configured to receive the program via the information terminal and execute the program. According to this structure, the information terminal does not need to have the program in the internal ROM in advance, so that the capacity of the ROM can be reduced.

The display on the character type LCD 52 is controlled via the d Crystal Display) drive circuit 51. Information relating to cooking and the like is displayed on the LCD 52 in a very limited manner.

In addition, the control circuit 6 has a memory 6M formed of a ROM therein. The memory 6M stores a control program executed by the control circuit 6 to realize each function of the microwave oven 1. still,
In FIG. 2, each constituent element existing around the control circuit 6 corresponds to a functional portion.

On the other hand, FIG. 3 is a functional block diagram showing an electrical configuration of the home terminal 2. The home terminal 2 is mainly composed of a control circuit 33 composed of a microcomputer, and like the microwave oven 1, is equipped with a BT adapter interface 34 and a BT adapter 35. The control circuit 33 uses the BT adapter 35 to communicate with the microwave oven 1 via a radio wave signal.

The control circuit 33 also communicates with other home electric appliances (for example, refrigerators, cooking heaters, rice cookers, etc.) having a Bluetooth interface as in the microwave oven 1 as required. Is configured to be possible. In this case, the home terminal 2 can centrally control these home electric appliances and can also notify information about the operating state of each home electric appliance.

An operation signal from the input unit 36 is given to the control circuit 33. Further, the control circuit 33 performs an informing operation such as displaying an image on the display (display unit) 37 based on the information transmitted from the microwave oven 1 or outputting a warning sound from the buzzer (or speaker) 38. It has become. The input unit 36 is the display 3
7 is configured as a touch panel on the screen.

Further, the control circuit 33 connects to the Internet (communication network) 40 through the external network communication unit 39 and accesses the cooking menu server 41 to require cooking information (cooking recipe) which is the content. It can be searched accordingly. The control circuit 33 transmits a control code according to the retrieved cooking recipe to a home electric appliance such as the microwave oven 1, and the microwave oven 1 or the like can also execute a cooking course corresponding to the transmitted control code. Has been done.

An ASP (Application Service Provider) 42, which is a server, is connected to the Internet 40. The ASP 42 is installed by the maker of the microwave oven 1, and the error treatment program 43 is arranged as content. The error treatment program 43 is designed to be downloaded in response to a request from the home terminal 2 side, as described later.

Further, the control circuit 33 has a memory 33M including a ROM therein. A control program for executing the function of the home terminal 2 is stored in the memory 33M, and an emergency operation program 44 transferred to the microwave oven 1 side and executed by the control circuit 6 is stored.
Is remembered.

Next, the operation of this embodiment will be described with reference to FIG. FIG. 4 is a sequence showing an example of processing performed among the microwave oven 1, the user, the home terminal 2 and the ASP 42, and shows a case where a failure occurs in the microwave oven 1. When the user operates the dial 9 of the operation panel 5 to appropriately select the cooking course to be performed by the microwave oven 1, the user operates the start key 7 (a).
Then, the control circuit 6 of the microwave oven 1 starts the operation according to the selected cooking course (b).

At this time, when the control circuit 6 recognizes that the user has misused the microwave oven 1 or that one of the functional parts has failed during the operation (error occurrence,
(C)), The error code is transmitted to the home terminal 2 via the BT adapter 32 (d).

Here, for example, if the infrared sensor 15 for detecting the temperature of the food is out of order, the control circuit 6 recognizes the failure state as follows. The sensor signal output from the infrared sensor 15 is given to the control circuit 6 via an amplifier (not shown). The control circuit 6 has a built-in A / D converter (not shown) and is adapted to A / D convert the sensor signal and read it.

If the A / D converter has, for example, 8 bits and the power supply voltage is 5V, the data value output when the input voltage is 5V is "255", and the input voltage is 0.
The data value output in the case of V is "0". In a normal use state of the microwave oven 1, the infrared sensor 15
The signal output by is never such a value. Therefore, when the read data is, for example, "250" or more or "5" or less, the control circuit 6 determines that the infrared sensor 15 has a failure, taking into consideration the adjustment error and the like. In this case, the error code transmitted to the home terminal 2 means the above failure.

Referring again to FIG. 4, when the control circuit 33 of the home terminal 2 receives the error code from the microwave oven 1, the control circuit 33 connects to the Internet 40 via the external network communication unit 39 to access the ASP 42. Then, the treatment program request is sent in the form of e-mail, for example, A
Send to SP42 (d). Upon receiving the transmitted program request, the ASP 42 receives the error handling program 4
3 is transmitted to the home terminal 2 (e).

When the control circuit 33 of the home terminal 2 receives the error treatment program 43 (f), the program 4
3 is executed to judge whether the error code transmitted from the microwave oven 1 means misuse by the user (g). If the user has misused (“YES”), the display 3 is provided with a coping method for eliminating the misused state.
7 is displayed (h). Then, when the user recognizes the correct usage by referring to the display on the display 37, the misuse state can be eliminated (i).

On the other hand, in the process (g), if the error code transmitted from the microwave oven 1 does not mean the user's misuse (“NO”), the error code indicates that the microwave oven 1 is out of order. It means that. Therefore, in this case, the control circuit 33 causes the display 37 to display information indicating that the microwave oven 1 has failed (j). That is, as shown in FIG. 7A, a message such as "A failure has occurred in the microwave oven" is displayed.

Further, the control circuit 33 judges whether or not the emergency operation is possible based on the content of the failure indicated by the error code (k). Here, the "emergency operation" means an operation that is performed temporarily using the remaining function or an alternative function without using the failed part. That is,
Depending on the point of failure, emergency operation may or may not be possible.

When emergency operation is possible ((k), "Y
ES "), the control circuit 33 displays on the display 37 to allow the user to select the emergency operation (l). That is, as shown in Fig. 7 (a), a message such as "Emergency operation is possible for this failure. Do you want to perform emergency operation?" Is displayed and "Yes" and "No" are input. Display the button.

At this time, when the user makes a selection with the input unit 36 (m) and touches the "Yes" input button, the control circuit 33 transfers the emergency operation program 44 to the microwave oven 1 (o). When the control circuit 6 of the microwave oven 1 receives the transferred emergency operation program 44, the control circuit 6 executes the program to perform the emergency operation (p).

In this case, the emergency operation may be performed in the following procedure, for example. That is, the control circuit 33
As shown in Fig. 7 (b), the display 37 shows "Start emergency operation. Please put food in the refrigerator to start.""[Notice] Only the weight sensor was temporarily used because the infrared sensor failed. Will automatically heat. The finished temperature may differ slightly. ”Is displayed. And microwave oven 1
When the start key 7 is operated by the user, the control circuit 6 starts the emergency operation.

Here, the emergency operation performed by the microwave oven 1 in the above process (p) will be described more specifically with reference to FIG. FIG. 5 shows a heating and cooking operation by the microwave oven 1 when the infrared sensor 15 is normal, that is, a flowchart of normal operation and a flowchart of emergency operation when the infrared sensor 15 fails. First, in the case of normal operation (step A1,
"NO"), the control circuit 6 detects the weight of the food material by the weight sensor 12 (step A2). Then, when the upper limit and the lower limit of the heating time are set according to the detected weight of the food (step A3), the heating operation is started (step A4).

During cooking, the control circuit 6 detects the temperature of the foodstuff by the infrared sensor 15 (step A).
5). Then, it is determined whether or not the upper limit of the heating time set in step A3 has been reached (step A6). If the upper limit has not been reached (“NO”), the cooking temperature selected in step A5 is selected. It is determined whether or not the cooking temperature (set temperature) of the food material set for the course has been reached (step A7). In step A7, if the temperature of the food material has not yet reached the set temperature (“N
O ") Return to step A4 to continue the heating operation.

When the temperature of the foodstuff reaches the set temperature during the loop of steps A4 to A7 as described above (step A7, "YES"), the control circuit 6 controls the heating time set in step A3. It is judged whether or not the lower limit is reached (step A8), and if the lower limit is not reached (“NO”), the process also returns to step A4. If the lower limit of the heating time is reached in step A8 (“Y
ES ”), and the cooking operation is completed.

Also, while the temperature of the food material has not reached the set temperature during the loop of steps A4 to A7, the upper limit of the heating time set in step A3 has been reached (step A6). "YES")
Also, the control circuit 6 ends the cooking operation at that time.

That is, as shown in FIG. 6, the control circuit 6 is
By detecting the temperature of the food being cooked by the infrared sensor 15, the heating time (T) set according to the weight (W) of the food in step A3 can have an upper limit and a lower limit. If the lower limit of the heating time is exceeded when the temperature of the food reaches the set temperature (steps A7, A8, "YES"), the cooking is finished without heating the food any more. You can

On the other hand, when the infrared sensor 15 is out of order and the emergency operation is performed (step A1, "YES"), the control circuit 6 detects the weight of the food by the weight sensor 12 as in step A2 (step B1). ), When the heating time is set according to the detected weight of the food (step B2), the heating operation is started (step B3). That is, in this case, the heating time set in step B2 is a time (standard time shown in FIG. 6) that does not have a width determined simply by the weight. Then, in step B4, the cooking is continued until the heating time elapses, and when the time elapses (“YE
S ”) Finish cooking.

As described above, since the infrared sensor 15 cannot be used in the emergency operation, the temperature of the food material during heating cannot be known and the heating time cannot be widened. However, even in this case, the cooking of the food is not completely disabled, and although it is assumed that the cooking accuracy is slightly deteriorated, there is no problem in performing the cooking immediately.

Referring again to FIG. When the control circuit 33 of the home terminal 2 receives the information indicating that the cooking operation (p) by the emergency operation is completed from the microwave oven 1, the display circuit 37 displays a display for allowing the user to select whether or not to perform the automatic failure diagnosis. (Q). Then, when the user makes a selection through the input unit 36 (r) and selects the automatic failure diagnosis ((s), “YES”), the control circuit 33 transmits an execution command for the automatic failure diagnosis to the microwave oven 1. Then,
The control circuit 6 of the microwave oven 1 executes automatic failure diagnosis (t).

Here, FIG. 8 is a flowchart showing the processing contents of the automatic failure diagnosis performed by the control circuit 6. In steps S1 to S5, the control circuit 6 diagnoses whether or not the inside lamp (not shown), the weight sensor 12, the inside temperature sensor 17, the hot air heater 22, and the magnetron 30 are out of order. Diagnosis is, for example, in the case of an internal light, that if there is no increase in the current value detected by the current sensor 16 even if the internal light is turned on, it is determined that there is a failure (disconnection) ("Y
ES ”) Judge.

In order to detect the failure of the weight sensor 12, for example, the user sets the rotating plate and the round plate in advance. Then, in that state, the weight sensor 1
If 2 detects a weight that is clearly different from the weight corresponding to those loads, it is diagnosed as a failure. Internal temperature sensor 1
With regard to No. 6, if a value close to the highest detection range or a value close to the lowest detection range is obtained, it is judged as a failure.

As for the hot air heater 22 and the magnetron 30, it is determined whether or not the current value changes when driven, as in the case of the interior light. Further, although not shown in FIG. 6, the current sensor 16 itself is also subjected to step S1.
It is possible to determine that a failure occurs when the current values when S5 to S5 are sequentially executed are exactly the same. Further, the invention is not limited to these, and the other functional parts are also appropriately diagnosed as long as the failure diagnosis is possible.

Then, the control circuit 6 makes a decision step S1.
If any of the steps S5 to S5 is executed and it is determined to be “YES”, a failure status indicating that each diagnosis target has a failure is stored in the RAM or the like according to each step (steps S6 to S10).

When each part is diagnosed as described above, the control circuit 6 determines whether or not there is a failure status stored in any of steps S6 to S10 (step S11). Then, if there is no failure status (“NO”), a no-abnormality code is stored (step S12), and if there is a failure status, (“YE
S ") A failure code corresponding to the status is stored (step S13), and the process ends. Then, the control circuit 6 transmits the diagnosis result of the automatic failure diagnosis (no abnormality code or failure code) to the home terminal 2.

In the process (t) of FIG. 4, the control circuit 6
Performs the automatic failure diagnosis, and when the user does not select the automatic failure diagnosis in the process (r), the control circuit 33 of the home terminal 2 determines whether the ASP 42 is notified of the failure information. The display 37 is caused to perform a display for selecting (u). When (v) contact is made based on the user's selection ((w), "YE
S "), the control circuit 33 transmits the diagnosis result to the ASP 42 via the Internet 40, for example, in the form of electronic mail (x). If the contact is not made based on the selection ((w), “NO”), the control circuit 33 ends the process.

As described above, according to the present embodiment, the control circuit 6 of the microwave oven 1, when any one of the plurality of functional parts fails, excludes the defective functional part and performs emergency operation. And transmits information about the failure to the home terminal 2, and the control circuit 33 of the home terminal 2 determines whether or not the emergency operation of the microwave oven 1 is possible based on the transmitted information. If it is determined that the emergency operation is possible, a message indicating that fact is displayed on the display 37 to notify the user.

That is, since more information can be notified by using the display 37 of the home terminal 2,
The information about the failure can be presented in a form that is easy for the user to understand. And home terminal 2
However, if the user is informed that the emergency operation is possible based on the transmitted failure information, the user can easily recognize the fact via the home terminal 2.
