Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cooker, and more particularly to a rice cooker having a learning function.

[0002]

2. Description of the Related Art In recent years, rice cookers, which cook rice and keep it warm after rice cooking, have become popular rapidly due to the convenience of rice cooking and maintenance after rice cooking. With the spread of rice cookers, consumers' tastes are diversifying, and not only plain rice cooked rice but also various cooked rice such as brown rice cooked rice and porridge cooked rice, or even the same cooked rice cooked rice, for example, "hard", There is a tendency that it is required to cook differently such as "soft seaweed", and in order to meet such diverse consumer needs, rice cookers with various rice cooking functions have been developed (for example, Japanese Patent Laid-Open No.
Various types are already on the market.

In such a rice cooker having various kinds of rice cooker functions, each rice cooker function is displayed on the display section provided on the outer surface of the rice cooker, and the display change is made by the user's switch operation. Do it,
When cooking rice, the rice cooking switch is turned on to start the rice cooking when the desired rice cooking function is displayed.

[0004]

However, in the conventional multi-function rice cooker of this type, since the display order of the rice cooker functions is set in advance in a fixed order, for example, the most frequently used case. When the display order of the selected rice cooking function is set to the end, the user needs to repeat the switch operation many times every time the rice cooking operation is performed to display the desired rice cooking function on the display section. However, the rice cooking operation is cumbersome and there is a point to be improved in terms of operability.

Therefore, the present invention has been made for the purpose of simplifying the selection operation of the rice cooking function during the rice cooking operation to improve the operability, and further improve the commercial value of the rice cooking jar.

[0006]

As a concrete means for solving such a problem, the present invention adopts the following configuration as illustrated in FIG.

In the invention according to claim 1, the control unit 2 is provided with the selecting means 54 for selecting the rice cooking function and the rice cooking function means 61 having a plurality of rice cooking functions such as white rice cooking and brown rice cooking.
3, a display unit 53 that displays the rice cooking function selected by the selection unit 54, and a rice cooking execution unit 55 that outputs a rice cooking execution signal to execute heating rice cooking based on the rice cooking function displayed on the display unit 53. And the cooked rice executing means 55
In a rice cooker including a heating rice cooker 56 that receives a rice cooker execution signal from the rice cooker, and determines that each rice cooker function of the rice cooker function means 61 has been selected and executed by the controller 23. Input from the selecting means 54, the execution determining means 81 to perform, the counting / storing means 57 that counts and stores the number of executions of each rice cooking function when the execution determining means 81 determines to execute the rice cooking function. Sometimes, the count value of the number of times of execution of each rice cooking function in the counting / storing means 57 is compared, and the rice cooking function having a large count value is prioritized over the rice cooking function having a small count value to be displayed on the display unit 53. 67 and 67 are provided.

According to a second aspect of the invention, in the rice cooker according to the first aspect, the execution determining means 81 is
It is characterized in that execution determination is performed on the condition that the rice cooking execution signal is input from the rice cooking execution means 55.

[0009]

According to the present invention, with such a configuration, the following operation can be obtained.

In the rice cooker according to the invention described in claim 1, when each rice cooking function of the rice cooking function means is selected and it is determined by the execution determination means, the number of times of execution is counted and stored. In the means, while being counted and stored for each rice cooking function,
At the time of input from the selection means, the priority display control means compares the count values of the number of executions for each rice cooking function, and the rice cooking function with the larger count value is displayed on the display unit in preference to the rice cooking function with the smaller count value.

Therefore, in the actual use of the rice cooker, every time the user selects a desired rice cooking function and cooks rice, the rice cooking function is sequentially counted and stored, and is stored in the rice cooking operation after the next time. The one with a large count value, that is, the rice cooking function with a high selection frequency is displayed on the display unit in preference to other ones. For example, when the user tries to select the rice cooking function currently displayed this time, It is sufficient to perform the rice-cooking execution operation as it is. Also, if you want to select a rice-cooking function other than this, by operating the selection means and changing the above display, the rice-cooking function other than the rice-cooking function already displayed is displayed. Since the items are displayed in descending order of selection frequency, the user only has to perform the rice cooking operation when the desired rice cooking function is displayed.

In the rice cooker according to the second aspect of the present invention, in addition to the above-described operation, the execution determination in the execution determining unit is performed on condition that the rice cooking execution signal is input from the rice cooking executing unit. Therefore, for example, if the rice cooking function is selected but the rice cooking function is not executed, the execution judgment is not made, and only when the rice cooking is actually executed using the selected rice cooking function. Execution determination is performed, and the number of times the rice cooking function is executed is counted and stored.

[0013]

Therefore, according to the rice cooker of the present invention, the following effects can be obtained.

(A) According to the rice cooker according to the invention described in claim 1, since the rice cooking function having a high selection frequency in the past is preferentially displayed on the display unit, the rice cooker can operate as desired by the user. The rice cooking function will be displayed first or with a smaller number of operations. As a result, for example, compared to the case where the rice cooking function is displayed in a fixed order regardless of the selection frequency, The annoyance at the time of operation is reduced as much as possible, the operability is further improved, and the commercial value as a rice cooker is further enhanced.

(B) In the rice cooker according to the invention described in claim 2, in addition to the effect described in (a), the rice cooker is executed only when rice is actually cooked by the selected rice cooking function. Since the execution judgment is made by the judgment means and the number of times the rice cooking function is executed is counted and stored, the display by the priority display means based on this count value corresponds to the actual rice cooking execution frequency. The reliability of the priority display is improved.

[0016]

Triacs 33 and 34 are connected between the heat retaining heater 26 and the commercial AC power supply 29 and between the shoulder heater 27 and the commercial AC power supply 329, respectively. The gates of these triacs 33, 34 are turned on / off by a command from the microcomputer 23.
Control signals from the PNP transistors 38 and 39 to be controlled are to be given.

The microcomputer 23 operates on the basis of the clock signal from the reference frequency generating circuit (OSC) 40, and the transistor 3 operates according to a predetermined program.
7, 38, 39 are controlled, and the rice cooker 2
5. Control power supply to the heat retention heater 26 and the shoulder heater 27. This power supply control is performed based on the output signal from the temperature sensitive element 72 incorporated in the center sensor 28. Reference numeral 71 is a rice cooker set sensor for detecting whether or not the rice cooker 6 is set.

In the microcomputer 23, the switches 41 to 44 and the indicator lights 45 to 48 are provided.
, A display unit 53 including a liquid crystal display element, and a buzzer 73 for notifying the completion of rice cooking are connected.

The microcomputer 23 constitutes a control unit in the scope of the claims. This will be described with reference to the functional block diagram of FIG. 4. The rice cooker heater 25 is set to the optimum state for cooked rice. A rice cooking function means 61 having three rice cooking function circuits, that is, a white rice cooking function circuit 62 for controlling, a brown rice cooking function circuit 63 for controlling an optimum state for brown rice cooking, and a porridge rice functional circuit 64 for controlling an optimum state for porridge rice cooking. When the rice is cooked by selecting each of the rice cooking function circuits 62 to 63, execution determining means 81 for determining selection / execution of the rice cooking function, and selection / execution of the execution determination means 81 are determined. In case of white rice cooking counter 5 which counts the number of selections and executions and stores it
8 and brown rice cooking counter 59 and porridge rice cooking counter 6
Counting / storing means 57 having three counters of 0;
Based on the output signal of the comparing means 65 and the comparing means 65 for comparing the stored count values (in other words, the number of selection executions) of the rice cooking counters 58 to 60, the rice cooked menu having a large stored count value is given priority. For the sake of illustration, the display unit 53 is provided with a display output unit 66 for outputting a display signal, and a priority display control unit 67.

The microcomputer 23
Is a selection unit 5 including the menu switch 41.
4 and the rice-cooking start switch 43 described above. That is, the display output means 66, as described above, selects the selection means 54.
When is not operated, the rice cooking menu having the largest stored count value is selected and displayed on the display unit 53. When the selecting means 54 is operated, this display is changed sequentially. However, even in this case, the selection means 54
The display order is set so that the display is sequentially changed from the rice cooking menu having a large stored count value to the rice cooking menu having a small memory count value for each operation.

When the rice cooking menu displayed on the display unit 53 is selected to cook rice, the rice cooking executing means 55 (that is, the rice cooking start switch 43) is set to ON. Then, the rice-cooking function circuit corresponding to the currently displayed rice-cooking menu is activated, and the required rice-cooking is performed by the heating-cooking means 56 (that is, the rice-cooking heater 25).

As described above, in the rice cooker of this embodiment, it should be noted that the rice cooking function which has been frequently used in the past is most likely to be selected in the next rice cooking, and the rice is repeatedly cooked. During this time, the frequency of selecting and executing each rice cooking function is learned, and at the next rice cooking, the rice cooking function (rice cooking menu) with the highest frequency of selection / execution is displayed first and unintentionally displayed first. Even if the rice-cooking function is not selected, the rice-cooking function that was most frequently selected and executed next is displayed with priority over the others, thereby simplifying the rice-cooking menu setting operation during rice-cooking. It is a thing.

The display control of the rice cooking function as described above will be described below.
More specifically, based on the flowcharts shown in FIGS. 5 to 7, first, after the control is started, a general reset is performed to renew the stored information in the microcomputer 23.
(Step S1). This is performed, for example, each time the backup battery is attached, and is not performed between the battery attachment and the next battery replacement (to prevent the loss of learning data).

Next, in actual control, first, in step S2, the menu switch 41 is set to ON if necessary. That is, as will be described later, either "white rice cooked rice", "brown rice cooked rice", or "porridge rice cooked" is already displayed on the display unit 53 based on the count value accumulated by several times of use. And also described later (steps S12, S1
If there is no accumulated data as shown in (7), "white rice cooked" is displayed, so it is not necessary to operate the menu switch 41 when selecting the rice cooking menu of that display, otherwise Is the menu switch 41
Because it is necessary to operate. Then, when the menu switch 41 is operated, the number of times of operation is counted (step S3).

Since there are three selectable rice cooking functions in this embodiment, the menu switch 41
As control modes corresponding to the number of times of operations, four cases are set: "no operation at all", "only once operation", "two times operation" and "three times operation".

First, in the case of "when no operation is performed",
6 through step S4 to step S6
Go to 11. In this step S11, the above three counters 58 corresponding to the three rice cooking functions, respectively.
Of 60 to 60, it is confirmed which counter has the first largest count value at present. When the counter of the first count value is confirmed, it is then determined whether the count value is 0 (step S12).

Here, when the count value is 0 (that is, at the time of first use), the process shifts to step S24 in FIG. 7 to display "white rice cooked rice" in a blinking display on the display unit 53 and cook rice. It is determined whether or not the start switch 43 is set to ON (step S25), and when the rice cooking start switch 43 is set to ON (that is, when the user wants "rice cooked rice"), the rice cooked rice display is displayed. The light 45 is turned on to show that the rice is currently "white rice cooked", and
Add the number of times 1 to the white rice cooking counter 58 and store it.
(Step S27), "white rice cooked" is executed (step S
28).

When rice cooking is completed, the white rice cooking indicator 45 is turned off (step S29), and the buzzer 73 informs "rice cooking completed" (step S30). After that, the heat retention indicator lamp 48 is turned on (step S45), and heat retention is executed (step S46).

Furthermore, it is judged whether or not the cancel switch 44 is set to ON (step S47). If the cancel switch 44 is set to ON, the cooked cooked rice is finished to prepare for the next cooked rice. It is determined that the control is in the initial state (step S47 → step S47).
2).

On the other hand, if the result of determination in step S47 is that the cancel switch 44 is not set to ON, it is determined based on the output signal of the rice cooker set sensor 71 whether or not the rice cooker 6 is in the set state ( In step S48), if the rice is in the set state, it is judged that the cooked rice has not been eaten yet and it is necessary to keep the heat. On the contrary,
If the rice cooker 6 is not in the set state, it is judged that the rice cooker is ready for the next rice cooking for a predetermined time (two seconds in this embodiment), and the initial control is restored. , Duration of unset state is 2
If it is within seconds, for some reason, temporarily cook rice 6
It has been removed and it is judged that it is still necessary to keep warm, and the warm state is continued.

In step S25, if the rice-cooking start switch 43 is not set to ON,
This is determined because there are cases where the user is simply trying to keep warm. That is, in step S8, the heat retention switch 42
It is determined whether or not is set to ON, and when it is set to ON, the heat retention program of step S45 and thereafter is executed. On the other hand, when the heat retention switch 42 is not set to ON (that is, when neither rice cooking nor heat insulation is desired), the rice cooking operation is simply delayed and the user wants to delete the current accumulated data. In this case, it is determined in step S9 whether the counter clear switch (not shown) is set to ON, and if it is set to ON, the accumulated data of all counters is stored. It is cleared to return to the initial operation state (step S10). On the other hand, when the counter clear switch is not set to ON, it is determined that the rice cooking operation is delayed, and in this case, the rice cooking start switch 4
It waits until 3 is set to ON (step S25).

On the other hand, in step S12, when it is determined that the current count value is not 0 (that is, when it has been used for cooking several times in the past and some data exists).
Determines whether the rice cooking function with the first count value is "white rice cooked rice", "brown rice cooked rice", or "porridge rice cooked" (steps S13, 14), and is "white rice cooked rice". If it is "brown rice cooked", the process proceeds to step S24 to cook white rice. If it is "brown rice cooked", step S3 is performed to cook brown rice.
If it is "rice cooked rice", the process proceeds to step S38 to cook rice. Note that the program for "brown rice cooking" in step S31 and subsequent steps and the program for "porridge rice cooking" in step S38 and subsequent steps are the same as those for "white rice cooking" described above, and a description thereof will be omitted.

Next, regarding the case where the menu switch 41 is "operated once" (step S4), in this case, the user wants to select the rice cooking function displayed first based on the accumulated data. Without this, the rice cooking function different from this is required. Therefore, when the menu switch 41 is operated once, the rice cooking function having the first count value is displayed and the rice cooking function having the second count value is displayed (step S16). Then, also in this case, similarly to the case of displaying the rice cooking function of the first count value, it is first determined whether or not the accumulated count value is 0 (step S17), and if it is 0, the count value is further increased. The first counter determines whether or not it corresponds to "white rice cooked rice" (step S20). If this is "white rice cooked rice", "brown rice" which is likely to be selected next to "white rice cooked rice""Cookingrice" is displayed (step S31),
If it is not "white rice cooked", "white rice cooked" is first displayed (step S24).

On the other hand, if the result of determination in step S17 is that the count value is not 0, this count value second
The rice cooking function is selected and displayed according to the accumulated data of the rank counter. That is, if this counter corresponds to "rice cooked rice", "rice cooked rice" is displayed (steps S18, 24), and if it corresponds to "brown rice cooked", "brown rice cooked" is displayed. It is displayed (steps S19, 31), and if it corresponds to "rice cooked rice", "rice cooked rice" is displayed (steps S19, 38). Since the program after displaying the predetermined rice cooking function is the same as the above-mentioned case, its explanation is omitted.

Next, regarding the case where the menu switch 41 is operated "twice" (step S5), in this case, in step S21, which counter the third count value corresponds to is the rice cooking function. Confirm that, if this corresponds to "rice cooked rice", display "white rice cooked" (steps S22, S24), and if it corresponds to "brown rice cooked", select "brown rice cooked". Display (Step S
23, S31), or if it corresponds to "rice cooked rice", "rice cooked rice" is displayed (step S23,
38). The description of the program after displaying the predetermined rice cooking function is omitted.

In this way, the menu switch 41 is set to 0 times
By operating the rice in the range of two times, the rice cooking functions with the highest selection frequency in the past are displayed in order, so that the user operates the menu switch 41 during rice cooking as long as the usage tendency similar to the past is maintained. The number of times has decreased,
The operability is improved by simplifying the operation.

On the other hand, unlike each of the above cases, when the menu switch 41 is operated three times (step S6), it is considered that there is an operation error of the menu switch 41 or a case where the temperature is kept warm. Therefore, in this case, first, the current menu switch count number is once cleared (step S7) to prepare for another switch operation (ie, selection operation of the rice cooking function), and the heat retention switch 4
2 is ON-OFF is determined (step S8), this is ON
If it has been set, the process proceeds to the heat retention program in step S45 and thereafter. If it is not set to ON, the counter is cleared (steps S9 and S10) or waits for switch operation (step S9).

In the above embodiment, three rice cooking functions, "white rice cooked rice", "brown rice cooked rice" and "porridge rice cooked rice" are provided, but the invention of the present application is not limited to this. In addition, for example, so-called cooking function such as "hard rice cooked", "soft rice cooked", "normal rice cooked" or "timer rice cooked" function is provided, and like these rice cook functions, those with high selection frequency are given priority. As a matter of course, it is possible to display them by displaying.

Further, in the above embodiment, a new counter learning switch is provided so that the user can clear the switch as needed, but in another embodiment, a new learning is possible. This may be cleared every time. Further, in this case, the counter clear switch may not be provided, and the accumulated data may be cleared when the menu switch 41 and the cancel switch 44 are simultaneously operated, for example.

Further, in the above embodiment, each counter stores the selection / execution count from that point in time when the corresponding rice cooking function is selected and executed even once, but other implementations are possible. In the example, from the viewpoint of preventing the rice cooking function that is preferentially displayed from being frequently changed and ensuring a stable priority display function, for example, the number of selections of a specific rice cooking function with respect to the total number of selections is a predetermined ratio or more ( , Half or more, or ⅔ or more), this can be stored.

In addition, in the above embodiment, the execution determination means 81 makes the execution determination on the condition that the rice cooking execution signal from the rice cooking execution means 55 is input. However, for example, the rice cooking execution means 55 executes the rice cooking. The execution determination is made only when the ON operation signal of the heat retention switch 42 is input together with the signal, or the execution determination is made only when the ON operation signal of the heat retention switch 42 and the ON operation signal of the cancel switch 44 are both input. It can also be done.
