(Embodiment 1)
FIG. 1 is an overall configuration diagram of a heating cooker according to the first embodiment of the present invention.

In FIG. 1, a kitchen cabinet 1, a multi-mouth induction heating cooker 2, two front induction heating means 3 for performing induction heating by placing a pan or the like, two rear induction heating means 4, and a fish or chicken And the grill 5 for baking.

  The operation and display unit is a first operation display unit 6 that performs operation of the grill 5 and the rear induction heating unit 4 and displays a state during heating, and a second operation display unit 7 that performs operation and display of the front induction heating unit 3. It is composed.

  The multi-mouth induction heating cooker 2 performs induction heating by placing a pan or the like on the ceramic glass, and is provided with temperature detection means (not shown) made of a thermistor on the lower side of the ceramic glass. The temperature of the pan, which is an object, is detected through the ceramic glass.

  FIG. 2 is a diagram showing an operation display unit of the heating cooker according to the first embodiment of the present invention, and corresponds to one of the front induction heating means 3 in the second operation display unit 7 of FIG. It is the figure which showed the operation display part in detail.

  In FIG. 2, the operating means 10 is automatically turned on / off under specific conditions such as a heating on / off switch 10a for turning on / off heating, an up / down switch 10b for raising / lowering the heating power during heating, boiling water, fried food, rice cooking, etc. The automatic cooking selection switch 10c that can select the state for temperature adjustment and sequence control, and the timer selection switch 10d that can set the heating off time or the like as a timer.

  Further, the level bar display means 11 is configured so as to know the heating power of heating together with the display of the heat power display means 12.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the heating setting of the front induction heating means 3 is about 80W for heat retention, about 120W for heating setting, about 330W for heating setting 2, about 440W for heating setting 3, about 750W for heating setting 4, and about 750W for heating setting 5 About 1000 W, heating setting 6 is about 1500 W, heating setting 7 is about 2000 W, heating setting 8 is about 2500 W, and heating setting 9 is about 3000 W.

  Next, the automatic cooking display means 13 displays the selected automatic cooking state when the automatic cooking selection switch 10c is selected, and when one is selected from boiling water, deep-fried food, and cooked rice.

Also, if it is fried automatically select cooking, and displays the temperature for de I digital display means 16 is thermostatic, automatic cooking preheating display section 14 until the set temperature is displayed through the preheat To do.

  When the target temperature is reached, the automatic cooking preheating display means 14 turns off the display and notifies the completion by an informing means (not shown) because the preheating is completed.

  Further, although it cannot be used during automatic cooking, it is possible to set an off timer time with the timer selection switch 10d during normal heating.

  When the timer time is set, the timer display unit 15 is displayed and the time can be displayed on the digital display means 16. Note that FIG. 2 shows a state where all the display portions are lit for the sake of explanation.

  FIG. 3 is a diagram showing a display during normal heating of the heating cooker according to the first embodiment of the present invention.

  In FIG. 3, the automatic cooking display means 13, automatic cooking preheat display means 14, timer display section 15, and digital display means 16 are turned off, level bar display means 11, and thermal power display means are displayed during normal heating that is not automatic cooking. 12 becomes a lighting state according to the setting.

  The display when the deep-fried food is selected by automatic cooking is demonstrated using FIG.

  FIG. 4 is a diagram showing a change in display of the deep-fried food temperature adjustment function of the cooking device according to the first embodiment of the present invention.

  In FIG. 4, when a pan filled with oil is placed and a fried food is selected, the automatic cooking display means 13 displays only the fried food and displays a set temperature of 180 on the digital display means 16. Until the set temperature is reached, the automatic cooking preheating display means 14 indicates that preheating is in progress.

  Further, all the level bars of the heating bar display means 11 are turned on simultaneously with the start of frying (FIG. 4 (a)), and the level bars of the heating bar display means 11 are turned off one by one as time passes by heating (FIG. 4 ( b) (c)), the level bar of the automatic cooking preheating display means 14 and the heating bar display means 11 is turned off simultaneously with completion of the preheating (FIG. 4D).

  Since the level bar gradually decreases, the user can visually know the time to complete preheating visually. This can prevent frustration without knowing when preheating is complete.

  Further, at the start of automatic cooking, as shown in FIG. 4, the level bar display means 11 is fully lit up and the number of bars is decreased as the preheating is completed. You can understand how long it takes to complete preheating without knowing the total number of bars.

  Next, how to change the display of the level bar display means 11 until the end of automatic cooking or the completion of preheating will be described.

  FIG. 5 is a block diagram of the level bar display means and the operation display unit of the cooking device according to the first embodiment of the present invention. FIG. 6 is a diagram showing a conversion table for estimating the time from the temperature detected by the temperature detection means of the cooking device according to the first embodiment of the present invention. FIG. 7 is a flowchart of a display operation during automatic cooking of the heating cooker according to the first embodiment of the present invention.

  In FIG. 5, the operation display unit 23 is a control unit 21 that performs display processing and heating control of various display units according to the input of the operation unit 10, and the display of the level bar display unit 11 according to the temperature of the temperature detection unit 20. The reference level dividing means 1 (22 in FIG. 5) is configured to change.

  The reference level dividing means 1 may be realized by software together with heating control using a microcomputer for the control unit 21 or may be realized by software of an independent microcomputer.

  Here, regarding the reference level dividing unit 1 (22 in FIG. 5) which visually displays a guide of the remaining time of cooking by changing the display of the level bar display unit 11, the remaining time is displayed on the bar of the level bar display unit 11. The operation of displaying the level bar display means 11 by dividing it into numbers will be described with reference to FIGS.

  First, the temperature detected by a temperature detection means (not shown) at the start of automatic cooking is compared with the diagram shown in the table of FIG. In this embodiment, it is assumed that the detected temperature is 30 ° C. Then, from the chart shown in FIG. 6, the time until the end of automatic cooking or completion of preheating is approximately 600 seconds (S101), and 600 seconds are divided by 10 which is the number of bars of the level bar display means 11 (S102) ( Standard level dividing means 1).

  As a result, the level bar 1 scale is 60 seconds, so the bar of the level bar display means 11 may be changed every 60 seconds (S103) and (S104).

  Here, automatic cooking is often limited to some extent, and if you estimate the time to completion at the automatic cooking start temperature in advance, even if the automatic cooking start temperature is different, without performing complicated calculations, It can be displayed roughly correctly.

  Further, every time the level bar of the level bar display means 11 changes by one scale, the temperature detected by the temperature detecting means at that time is again estimated again with reference to the diagram shown in the table of FIG.

  That is, when automatic cooking is started when the temperature detected by the temperature detection means is 30 ° C., all level bars of the level bar display means 11 are displayed, and after 1 second, the scale is turned off and the remaining 9 scales are turned on. (S104). At that time, the temperature is detected again by the temperature detecting means (S100).

  When the temperature at that time is 60 ° C., the remaining time until the end of automatic cooking or the completion of preheating is set to 480 seconds (S101) from the chart shown in FIG. 6 (S102), and 480 seconds are divided by the number of level bars of 9 (S102). .

  Thus, the next level bar scale is about 53 seconds, and changes from every 60 seconds to every 53 seconds. As a result, the time is re-estimated every time one scale is changed, so that correction can be made even when a cooking item is increased or decreased during cooking, or a deviation due to the material of the pan occurs.

  Next, a case will be described in which the level bar display is changed according to the temperature detected by the temperature detecting means instead of changing the level bar display from the estimated time. When cooking is performed to adjust the temperature like fried food, when the oil temperature is first set to 180 ° C, preheating is completed at 190 ° C in consideration of overshoot. It is like that.

  And if the temperature at the time of an automatic cooking start is 30 degreeC, the temperature difference 160 degreeC until completion will be divided | segmented by the number of level bars 10 (standard level division means 2). As a result, the level bar scale is 16 ° C., so that the level bar is changed every time the temperature detected by the temperature detecting means increases by 16 ° C.

  As a result, the level bar display change category is determined from the temperature at the start and end of automatic cooking, or the completion of preheating, so there will be a crawl when cooking is increased or decreased during cooking or due to the material of the pan. Level bar can be displayed.

  In addition, the level bar is divided not uniformly but weighted so that the divided temperature width becomes shorter as the automatic cooking ends or the preheating is completed than when automatic cooking starts.

  In other words, in the case of uniform division, the level bar change temperature is 46, 62, 78, 94, 110, 126, 142, 158, 174 ° C and 16 ° C intervals, but 70, 100, 126, 146, 156, 166, 173, 180, 185 ° C.

  Usually, since it tends to be felt as time passes, the level bar display is quickly changed as the end of automatic cooking or the completion of preheating is approached, and the user's frustration can be reduced.

  Even if the same temperature range continues as in the present embodiment, there is no significant difference if the temperature range becomes shorter as the automatic cooking starts and ends or nears completion of preheating.

  FIG. 8 is a diagram showing another display unit of the heating cooker according to the first embodiment of the present invention.

  Note that FIG. 8 shows a state where all the display portions are lit for the sake of explanation.

  In FIG. 8, when the positional relationship between the level bar display means 11 and the digital display means 16 is as shown in FIG. 8, the minimum level is displayed at the start of automatic cooking, and the number of level bars of the level bar display means is displayed over time. Increase and turn on all level bars at the end of automatic cooking or when preheating is complete. As a result, it is possible to visually represent the end of automatic cooking or completion of preheating.

  As described above, in the present embodiment, the heating means for heating the object to be heated, the level bar display means for displaying the current thermal power with the level bar, and the display with the level bar for associating the thermal power Thermal power display means, digital display means for digitally displaying temperature and time, automatic cooking display means for displaying which automatic cooking is performed when automatic cooking is being performed, and heating on / off and automatic cooking are set An operation means, and during automatic cooking, the selected automatic cooking is displayed on the automatic cooking display means, and the thermal power display means is not displayed, and an indication of the time until completion of automatic cooking or completion of preheating, etc. Is visually displayed on the level bar display means, during automatic cooking, the remaining time until completion of automatic cooking or completion of preheating is normally displayed on the level bar indicating the thermal power. Can be displayed clearly in Satoshiteki, without increasing the display unit, it is possible to improve the usability.

  As described above, the cooking device according to the present invention visually displays the remaining time until the completion of the automatic cooking or the completion of the preheating using the level bar indicating the normal heating power at the time of automatic cooking. The display can be visually expressed without increasing the amount of light, and it is possible to prevent the contents of the display unit from being small and difficult to see, which is effective for all cooking devices installed in kitchens of ordinary households.
