Further, by providing the discharge groove 223 extending forward on the outer circumference of the rib 222, foreign matter such as liquid accumulated on the outer circumference of the rib 222 can be discharged from the front, and the invasion of the liquid into the operation board 24 is further suppressed. be able to.

When the operation dial 233 is pressed in the initial state of FIG. 6, as shown in FIG. 7, the position of the flange portion 331a of the dial rotating portion 331 does not change, and the cover 330 moves in the axial direction. At this time, the pressing portion 332 arranged in the center of the cover 330 moves in the axial direction in response to the pressing operation of the cover 330, and presses the switch 241 of the operation board 24.

Further, when the operation dial 233 is rotated, the dial rotating portion 331 and the encoder rotating portion 242a rotate in conjunction with the rotation of the cover 330. Then, the rotation amount of the operation dial 233 is detected from the rotation displacement amount of the encoder rotation unit 242a. In the present embodiment, the operation dial 233 is configured to be rotatable in the clockwise direction and the counterclockwise direction, but may be configured to be rotatable in either the clockwise direction or the counterclockwise direction.

Next, the heating control by the control unit 7 of the heating cooker 100 of the present embodiment will be described. FIG. 8 is a flowchart showing an example of a heating operation of the cooking cooker 100 according to the first embodiment. The processing of this flowchart is executed by the control unit 7. First, it is determined whether or not the power of the cooking cooker 100 is turned on (S1). The power of the cooking cooker 100 is turned on when the power button 237 is operated by the user. If the power is not turned on (S1: NO), it waits until it is turned on.

On the other hand, when the power is turned on (S1: YES), it is determined whether or not the operation dial 233 has been rotated (S2). Here, when the encoder 242 detects the movement of the operation dial 233 in the rotation direction, it is determined that the operation dial 233 has been rotated. The rotation direction of the operation dial 233 may be limited to either the clockwise direction or the counterclockwise direction, or may be rotatable in both directions. If the operation dial 233 is not rotated (S2: NO), it waits until it is rotated. Then, when the operation dial 233 is rotated (S2: YES), the initial heating setting of the heating means corresponding to the rotated operation dial 233 is set on the liquid crystal display unit corresponding to the rotated operation dial 233. It is displayed (S3). The initial heating setting is, for example, the initial setting value of the heating power of the heating means or the cooking mode.

Next, it is determined whether or not the operation dial 233 has been rotated (S4). If the operation dial 233 is not rotated (S4: NO), the process proceeds to step S6. On the other hand, when the operation dial 233 is rotated (S4: YES), the heating setting is changed from the initial heating setting (S5). Here, for example, the heating power of the corresponding heating means is increased or decreased, or the cooking mode is changed. Then, it is determined whether or not the operation dial 233 is pressed (S6). Here, when the switch 241 detects the axial movement of the operation dial 233, it is determined that the operation dial 233 has been pressed.

If the operation dial 233 is not pressed (S6: NO), the process returns to step S4. On the other hand, when the operation dial 233 is pressed (S6: YES), the heating means corresponding to the operation dial 233 starts heating at the selected heating setting (S7). Then, it is determined whether or not the operation dial 233 is pressed during heating (S8), and if the operation dial 233 is not pressed (S8: NO), heating is continued. On the other hand, when the operation dial 233 is pressed (S8: YES), heating is stopped (S9).

Next, the operation of the display operation unit 23 of the cooking cooker 100 of the present embodiment will be described. FIG. 9 is a diagram showing the operation of the left display operation unit 23L until the start of heating of the first heating means 3L according to the first embodiment. Although the left display operation unit 23L will be described in FIG. 9, the operation of the right display operation unit 23R until the start of heating of the first heating means 3R is the same. As shown by arrows in the figure, the left display operation unit 23L transitions in the order of FIGS. 9 (a), (b), (c), and (d). The operation of the left display operation unit 23L is controlled by the control unit 7 in response to the operation of the operation dial 233L.

FIG. 9A shows a left display operation unit 23L in a state where the first heating means 3L is stopped. Immediately after the power is turned on, nothing is displayed on the liquid crystal display unit 231L as shown in FIG. 9A. As a modification, the liquid crystal display unit 231L may display a figure or characters indicating that the next heating procedure, for example, the operation dial 233L is to be turned.

When the operation dial 233L is rotated in the state shown in FIG. 9A, the initial heating setting of the first heating means 3L is displayed on the liquid crystal display unit 231L. Specifically, as shown in FIG. 9B, the initial set value of the thermal power of the first heating means 3L is displayed blinking. In the example of FIG. 9B, the initial setting value is "heat power 4".

When the operation dial 233L is rotated in the state shown in FIG. 9B, the heating setting of the first heating means 3L is changed. For example, the control unit 7 increases the set thermal power of the first heating means 3L when the operation dial 233L is rotated clockwise, and increases the set thermal power of the first heating means 3L when the operation dial 233L is rotated counterclockwise. To reduce. Then, as shown in FIG. 9C, the display of the liquid crystal display unit 231L is changed according to the change of the set thermal power, and is displayed blinking. FIG. 9C shows a case where the operation dial 233L is rotated clockwise and the display content is changed from “thermal power 4” to “thermal power 5”.

When the operation dial 233L is pressed while the thermal power setting is blinking on the liquid crystal display unit 231L, heating of the first heating means 3L is started, and as shown in FIG. 9D, the liquid crystal display unit 231L The blinking display of is changed to the lit display. Further, the level display unit 232L is turned on. By changing the liquid crystal display unit 231L from blinking to lit, it is possible to indicate to the user that the state before heating has been changed to during heating. The area of the level display unit 232L that is lit changes depending on the set thermal power. For example, when there are 10 levels of thermal power that can be set and the thermal power being set is "thermal power 5", the lighting area of the level display unit 232L is halved of the total. Specifically, the level display unit 232L is in a state in which the left half of the total lighting area is lit and the right half is extinguished.

The lighting area of the level display unit 232L increases as the set thermal power increases, and decreases as the set thermal power decreases. By changing the lighting area of the level display unit 232L according to the set thermal power in this way, the user can intuitively recognize the thermal power level. At this time, the liquid crystal display unit 231L displays characters of the set thermal power.

Then, when the operation dial 233L is pressed during heating, the heating is stopped, and the left display operation unit 23L returns to the state shown in FIG. 9A. In addition to pressing the operation dial 233L during heating, the operation dial 233L is rotated counterclockwise to minimize the set thermal power, and then the operation dial 233L is further rotated counterclockwise. , The heating may be stopped.

Further, by providing a structure that suppresses the intrusion of foreign matter into the operation dial 233 while enabling the operation of the operation dial 233 in the rotation direction and the axial direction, the operability is maintained and the failure of electronic parts is prevented. It can be suppressed. Further, by providing a structure for suppressing the intrusion of foreign matter into the operation dial 233, the operation dial 233 can be arranged in the vicinity of the top plate 21. As a result, the operability of the user is improved as compared with the case where the operation dial 233 is provided on the front surface of the cooking cooker 100.

In the first embodiment, when the operation dial 233 is rotated, the first heating means 3R or 3L is set to the heating ready state, and when the operation dial 233 is pressed, the first heating means 3R or 3L is set. However, the configuration is not limited to this. For example, when the operation dial 233 is pressed, the first heating means 3R or 3L is in a heating ready state, and when the operation dial 233 is rotated, heating by the first heating means 3R or 3L is started. May be good.

FIG. 10 is a diagram showing the operation of the left display operation unit 23L until the start of heating of the first heating means 3L according to the modified example of the first embodiment. Although the left display operation unit 23L will be described in FIG. 10, the operation of the right display operation unit 23R until the start of heating of the first heating means 3R is the same. As shown by arrows in the figure, the left display operation unit 23L transitions in the order of FIGS. 10 (a), (b), (c), and (d). The operation shift of the left display operation unit 23L is controlled by the control unit 7 in response to the operation of the operation dial 233L.

FIG. 10A shows a left display operation unit 23L in a state where the first heating means 3L is stopped. Immediately after the power is turned on, nothing is displayed on the liquid crystal display unit 231L as shown in FIG. 10 (a). Then, in this modification, when the operation dial 233L is pressed, the first heating means 3L is set to the heating ready state. FIG. 10B is a left display operation unit 23L in a state where the operation dial 233L is pressed. At this time, the liquid crystal display unit 231L displays a figure that guides the operation dial 233 to rotate.

When the operation dial 233L is rotated in the state of FIG. 10B, heating by the first heating means 3L is started. At the start of heating, heating is started with "heat power 4" which is a preset initial heating power. Then, as shown in FIG. 10C, the liquid crystal display unit 231L is lit and displayed with the initial thermal power "thermal power 4", and the level display unit 232L is lit. The lighting area of the level display unit 232L changes depending on the set thermal power.

When the operation dial 233L is rotated clockwise during heating by the first heating means 3L, the heating power is increased, and when it is rotated counterclockwise, the heating power is decreased. FIG. 10D shows an example in which the operation dial 233L is rotated in two steps in the clockwise direction during heating by the first heating means 3L. In this case, the changed thermal power "thermal power 6" is lit and displayed on the liquid crystal display unit 231L, and the lighting area of the level display unit 232L becomes large.

It is possible to suppress malfunctions caused by being operated without any problems.

Embodiment 2.
The second embodiment will be described. In the second embodiment, selection of a cooking mode using the operation dial 233 will be described. The configuration of the cooker 100 of the second embodiment is the same as that of the first embodiment.

FIG. 11 is a diagram showing the operation of the left display operation unit 23L until the start of heating of the first heating means 3L according to the second embodiment. Although the left display operation unit 23L will be described in FIG. 11, the operation of the right display operation unit 23R until the start of heating of the first heating means 3R is the same. As shown by arrows in the figure, the left display operation unit 23L transitions in the order of (a), (b), (c), (d), and (e) in FIG. The operation of the left display operation unit 23L is controlled by the control unit 7 in response to the operation of the operation dial 233L.

FIG. 11A shows a left display operation unit 23L in a state where the first heating means 3L is stopped. Immediately after the power is turned on, nothing is displayed on the liquid crystal display unit 231L as shown in FIG. 11A. At this time, by rotating the operation dial 233L, the cooking mode in the first heating means 3L can be selected. Here, there are three cooking modes selected: "heating", "fried food", and "simmering". "Heating" is a mode in which heating is performed with a set heating power. "Fried food" is a mode that automatically adjusts the heating power so that it reaches the set temperature. "Simmering" is a mode in which high heat and low heat are periodically repeated according to the set heat.

FIG. 11B is a left display operation unit 23L in a state where the operation dial 233L is rotated. Here, "heating" is selected as the preset initial setting cooking mode, and "heating" is displayed on the liquid crystal display unit 231L. When the operation dial 233L is further rotated in the state shown in FIG. 11B, the cooking mode is changed.

The cooking mode is changed according to the rotation of the operation dial 233L. For example, when the operation dial 233L is rotated clockwise, the cooking mode is changed in the order of "heating"-> "fried food"-> "simmering"-> "heating"->. When the operation dial 233L is rotated counterclockwise, the cooking mode is changed in the order of "heating"-> "simmering"-> "fried food"-> "heating"-> ..., and the cooking mode is changed from the clockwise direction. The order of doing is reversed. At this time, the selected cooking mode is displayed on the liquid crystal display unit 231L. For example, when "fried food" is selected as the cooking mode as shown in FIG. 11C, the characters "fried food" are displayed on the liquid crystal display unit 231L.

When the operation dial 233L is pressed while the "fried food" is selected, heating by the first heating means 3L is started according to the cooking mode of the "fried food". At this time, as shown in FIG. 11D, the liquid crystal display unit 231L has the characters "180" indicating that the set temperature of the "fried food" is 180 ° C. and the characters "fried food" indicating the cooking mode.

Further, the cooking mode may be displayed graphically.

Further, when heating by the first heating means 3L is started, the level display unit 232L lights up. The lighting area of the level display unit 232L has a size corresponding to the set temperature. When "fried food" is selected as the cooking mode, the set temperature can be set in 7 steps from 140 ° C. to 200 ° C., and the lighting area of the level display unit 232L increases as the set temperature increases. As shown in FIG. 11D, when the set temperature is 180 ° C., the lighting area of the level display unit 232L is 5/7 of the whole.

If the operation dial 233L is not operated for a preset time or longer during the selection of the cooking mode shown in FIG. 11 (c), all operations may be canceled and the state of FIG. 11 (a) may be restored. ..

When the operation dial 233L is rotated after the start of heating, the set temperature is changed, and the display of the liquid crystal display unit 231L and the lighting area of the level display unit 232L are changed according to the changed set temperature. When the operation dial 233L is rotated clockwise, the set temperature is increased, and when it is rotated counterclockwise, the set temperature is decreased. The upper limit of the set temperature is 200 ° C., and the lower limit is 140 ° C. Even when the operation dial 233L is continuously rotated clockwise or counterclockwise, it is not set to 200 ° C. or higher or 140 or lower. FIG. 11 (e) shows an example when the set temperature is changed to 190 ° C. In this case, as shown in FIG. 11 (e), the character "190" indicating the set temperature of 190 ° C. is displayed on the liquid crystal display unit 231L, and the lighting area of the level display unit 232L is 6/7 of the whole. Become.

Then, when cancel is selected and the operation dial 233L is pressed, the process returns to FIG. 13 (c) in which the cooking mode can be selected. In the example of FIG. 13, when cancellation is selected, the state returns to the previous state (FIG. 13 (c)), but the heating may be returned to the state of FIG. 13 (a). Further, the cancellation may be selected when the cooking mode is selected. That is, in the cooking mode selection state shown in FIG. 13C, any one of "heating", "fried food", "simmering", and "returning" may be selected.

FIG. 14 is a flowchart showing an example of a heating operation of the cooking cooker 100 according to the third embodiment. The processing of this flowchart is executed by the control unit 7. First, it is determined whether or not the power of the cooking cooker 100 is turned on (S101). The power of the cooking cooker 100 is turned on when the power button 237 is operated by the user. If the power is not turned on (S101: NO), it waits until it is turned on.

On the other hand, when the power is turned on (S101: YES), it is determined whether or not the operation dial 233 has been rotated (S102). If the operation dial 233 is not rotated (S102: NO), it waits until it is rotated. Then, when the operation dial 233 was rotated (S102: YES), it was rotated to the liquid crystal display unit (hereinafter, referred to as "liquid crystal display unit 231L" as an example) corresponding to the rotated operation dial 233. The cooking mode corresponding to the operation dial 233 is displayed (S103).

Next, it is determined whether or not the operation dial 233 has been rotated (S104). If the operation dial 233 is not rotated (S104: NO), the process proceeds to step S106. On the other hand, when the operation dial 233 is rotated (S104: YES), the cooking mode is selected (S105). Here, the cooking mode is selected according to the rotation direction of the operation dial 233, and the selected cooking mode is displayed on the liquid crystal display unit 231L.

Then, it is determined whether or not the operation dial 233 is pressed (S106), and if the operation dial 233 is not pressed (S106: NO), the process returns to step S104. On the other hand, when the operation dial 233 is pressed (S106: YES), the selection of the cooking mode is determined, and the liquid crystal display unit 231L displays the initial heating power setting in the selected cooking mode (S107). For example, when "fried food" is selected, "180 ° C." is displayed as the initial set temperature.

Next, it is determined whether or not the operation dial 233 has been rotated (S108). If the operation dial 233 is not rotated (S108: NO), the process proceeds to step S110. On the other hand, when the operation dial 233 is rotated (S108: YES), the thermal power setting is changed (S109). Here, the heating power setting in the cooking mode is changed according to the rotation direction of the operation dial 233, and the changed heating power setting is displayed on the liquid crystal display unit 231L. The change of the heating power setting includes the setting of "return" for canceling the setting of the cooking mode as described with reference to FIG.

Then, it is determined whether or not the operation dial 233 is pressed (S110), and if the operation dial 233 is not pressed (S110: NO), the process returns to step S108. On the other hand, when the operation dial 233 is pressed (S110: YES), it is determined whether or not "return" is set (S111). If "return" is set (S111: YES), the process proceeds to step S104.

On the other hand, when a heating power other than "return" is set (S111: NO), heating in the selected cooking mode and heating power setting is started in the heating means corresponding to the operation dial 233 (S112). Then, it is determined whether or not the operation dial 233 is pressed during heating (S113), and if the operation dial 233 is not pressed (S113: NO), heating is continued. On the other hand, when the operation dial 233 is pressed (S113: YES), heating is stopped (S114).

Embodiment 4.
The fourth embodiment will be described. In the fourth embodiment, the heating setting in the heating chamber 5 by the second heating means 6 using the operation dial 233C will be described. The configuration of the cooking cooker 100 of the fourth embodiment is the same as that of the first embodiment.

As a cooking mode in the heating chamber 5, the cooking cooker 100 uses an automatic cooking mode that automatically determines the amount of foodstuffs contained in the heating chamber 5 and automatically adjusts the heating power based on the set heating power. It has a manual mode that heats at the heating power and time specified by the person. Automatic cooking modes include "fillet" and "grilled". In manual mode, there are "manual strong", "manual medium", "manual weak" and so on.

FIG. 15 is a diagram showing the operation of the central display operation unit 23C until the start of heating of the heating chamber 5 according to the fourth embodiment, and shows the operation when the automatic cooking mode is selected. As shown by arrows in the figure, the center display operation unit 23C transitions in the order of (a), (b), (c), (d), and (e) in FIG. The operation of the central display operation unit 23C is controlled by the control unit 7 in response to the operation of the operation dial 233C.

FIG. 15A shows a central display operation unit 23C in a state where the second heating means 6 is stopped. Immediately after the power is turned on, nothing is displayed on the liquid crystal display unit 231C as shown in FIG. 15 (a). At this time, by rotating the operation dial 233C, the cooking mode in the heating chamber 5 can be selected. FIG. 15B is a central display operation unit 23C when the operation dial 233C is rotated. Here, the automatic cooking mode "fillet" is selected as the preset initial cooking mode, and "fillet" is displayed on the liquid crystal display unit 231C. When the operation dial 233C is further rotated in the state shown in FIG. 15B, the cooking mode is changed.

The cooking mode is changed according to the rotation of the operation dial 233C. For example, when the operation dial 233C is rotated clockwise, the cooking mode changes from "fillet" → "figure roasting" → "manual strong" → "manual medium" → "manual weak" → "return" → "fillet" → It is changed in the order of ... When the operation dial 233C is rotated counterclockwise, the cooking mode changes from "fillet" → "return" → "manual weak" → "manual medium" → "manual strong" → "figure roasting" → "fillet" → ・・ ・ It is changed in the order of. At this time, the selected cooking mode is displayed on the liquid crystal display unit 231C. For example, when "figure-yaki" is selected as the cooking mode as shown in FIG. 15C, the characters "figure-yaki" are displayed on the liquid crystal display unit 231C.
