It is a fourth figure explaining the air flow generated from the heating cooker 100 which concerns on Embodiment 1. FIG.

Hereinafter, the air flow generated from the cooking cooker 100 according to the first embodiment will be described with reference to FIGS. 4 to 7. The arrows in FIGS. 4 to 7 indicate the air flow.
When cooking is started in the cooking cooker 100, the heating unit 120, the cooling fan 124, and the ventilation fan 300 of the cooking cooker 100 operate, and as shown in FIG. 4, they are sucked from the intake port 107 and the main body 101. After passing through the inside and cooling the high frequency inverter circuit 121 and the heating unit 120, the air exhausted from the exhaust port 106 (hereinafter referred to as the first air 161) and the heated portion placed on the top plate 102 are heated. Air mixed with water, oil, etc. from the object to be heated contained in the container 200 (hereinafter referred to as the second air 162) is generated, and they are directed toward the range hood 400 arranged above the cooking cooker 100. Flow.

After a certain period of time has passed from the start of cooking in the cooking device 100, the first air 161 and the second air 162 from the cooking device 100 reach the ventilation fan 300 in the range hood 400, as shown in FIG. To do. At this time, the flow of the first air 161 (hereinafter referred to as the first airflow) is in a stable state, but the flow of the second air 162 (hereinafter referred to as the second airflow) is inside the heated container 200. The temperature of the object to be heated is not high and is not stable. Therefore, it is difficult for the second air 162 to collect in the ventilation fan 300.

When a certain period of time elapses after the cooking is started in the heating cooker 100, the temperature of the object to be heated in the container 200 to be heated becomes high and the second air flow becomes stable as shown in FIG. Therefore, the second air 162 is likely to collect in the ventilation fan 300.

After the second airflow becomes stable, as shown in FIG. 7, even if the rotation speed of the cooling fan 124 becomes lower than that at the start of cooking, the first and second airflows are maintained in a stable state. ..

As described above, after a certain period of time has passed since the cooking was started in the cooking device 100, the temperature of the object to be heated became high and the second air flow became stable, so that the second air 162 easily gathered in the ventilation fan 300 and became outside. Easy to be exhausted. That is, efficient ventilation can be performed. However, immediately after the cooking is started in the cooking device 100, the temperature of the object to be heated is not high and the second airflow is not stable, so that the second air 162 is difficult to collect in the ventilation fan 300 and is exhausted to the outside. It's hard. In other words, it is difficult to perform efficient ventilation.

Therefore, in the cooking device 100 according to the first embodiment, the rotation speed of the cooling fan 124 is increased immediately after the cooking is started. By doing so, the second airflow is assisted by the first airflow, and the second air 162 is easily collected in the ventilation fan 300. Then, in the cooking cooker 100, the rotation speed of the cooling fan 124 is lowered after the object to be heated becomes high temperature and the second air flow becomes stable. By doing so, it is possible to suppress power consumption and noise while maintaining a state in which the second air 162 easily collects in the ventilation fan 300.

That is, the heating cooker 100 is efficient by increasing the rotation speed of the cooling fan 124 until the second air flow stabilizes and decreasing the rotation speed of the cooling fan 124 after the second air flow stabilizes. Power consumption and noise can be suppressed while providing good ventilation.

The control device 150 heats from the operation unit 104. When the operation start instruction of the unit 120 is received, the operation of the heating unit 120 is started, the cooling fan 124 is operated at the first rotation speed, and then the cooling fan 124 is operated at the second rotation speed lower than the first rotation speed. It is what makes you.

According to the heating cooker 100 according to the first embodiment, after the operation of the heating unit 120 is started, the rotation speed of the cooling fan 124 is increased until the air flow from the object to be heated is stabilized, and the air is exhausted. The flow of air from the port 106 assists the flow of air from the object to be heated, and after the flow of air from the object to be heated is stabilized, the rotation speed of the cooling fan 124 can be reduced. Therefore, it is possible to suppress power consumption and noise while performing efficient ventilation. Further, since the rotation speed of the cooling fan 124 is controlled, it is not necessary to control the ventilation fan 300.

FIG. 10A is a first flowchart showing an example of control of the cooling fan 124 of the heating cooker 100 according to the second embodiment of the present invention, and FIG. 10B is a heating cooker according to the second embodiment of the present invention. It is a second flowchart which shows an example of the control of the cooling fan 124 of 100, and FIG. 11 is a timing chart which shows an example of the control of the cooling fan 124 of the heating cooker 100 which concerns on Embodiment 2 of this invention.

Hereinafter, the control of the cooling fan 124 of the cooking device 100 according to the second embodiment will be described with reference to FIGS. 8B, 10A, 10B, and 11. It is assumed that the ventilation fan 300 is operating at a set strength (for example, "medium").

When the operation control unit 153 receives the operation disclosure instruction of the heating unit 120 from the operation unit 104 (YES in step S201), the main control unit 151 operates the heating unit 120 with the thermal power set by the inverter circuit drive unit 155. (Step S202), the temperature detection unit 123 determines whether or not the temperature of the heated container 200 is equal to or higher than the reference temperature T1 (step S203).

When the main control unit 151 determines that the temperature of the container 200 to be heated is equal to or higher than the reference temperature T1 (YES in step S203), the cooling fan 124 is operated by the cooling fan motor drive unit 154 as shown in FIG. 11C. Is operated at the rotation speed r1 (step S204), and the time measurement is started by the timer unit 157 (step S205). Here, the rotation speed r1 is a rotation speed required to assist the second air flow, and is set in advance based on an actual measurement result or the like.

After step S205, the main control unit 151 refers to the reference time t1 stored in the storage unit 156, and determines whether or not the measurement time by the timer unit 157 has passed the reference time t1 (step S206). Here, the reference time t1 is the time from when the cooling fan 124 is operated at the rotation speed r1 until the second airflow stabilizes, and is set in advance based on the actual measurement results and the like.

When the main control unit 151 determines that the measurement time by the timer unit 157 has passed the reference time t1 (YES in step S206), the main control unit 151 is cooled by the cooling fan motor drive unit 154 as shown in FIG. 11 (c). The fan 124 is operated at a rotation speed r2, which is lower than the rotation speed r1 (step S256), and the notification unit 111 notifies that power is being saved (step S257). Here, the rotation speed r2 is the rotation speed required to maintain the stable state of the first airflow and the second airflow, and is preset by an actual measurement result or the like.

In the second embodiment, when the rotation speed of the cooling fan 124 is switched from the rotation speed r1 to the rotation speed r2, the notification unit 111 notifies that power is being saved, but the present invention is not limited to this, and the air flow is not limited to this. You may notify that it is stable, or you may notify both of them.

On the other hand, in step S203, when the main control unit 151 determines that the temperature of the heated container 200 is lower than the reference temperature T1 (NO in step S203), the temperature detecting unit 123 uses the temperature of the heated container 200 as a reference. It is determined whether or not the temperature is T2 (<T1) or higher (step S207).

When the main control unit 151 determines that the temperature of the container 200 to be heated is equal to or higher than the reference temperature T2 (first reference value) (YES in step S207), the cooling fan motor is driven as shown in FIG. 11B. The cooling fan 124 is operated at the rotation speed r1 by the unit 154 (step S208), and the time measurement is started by the timer unit 157 (step S209).

After step S209, the main control unit 151 refers to the reference time t2 stored in the storage unit 156, and determines whether or not the measurement time by the timer unit 157 has elapsed the reference time t2 (step S210). Here, the reference time t2 is the time from when the cooling fan 124 is operated at the rotation speed r1 until the second airflow stabilizes, and is set in advance based on the actual measurement results and the like.

When the main control unit 151 determines that the measurement time by the timer unit 157 has passed the reference time t2 (YES in step S210), the main control unit 151 is cooled by the cooling fan motor drive unit 154 as shown in FIG. 11B.

In addition, the cooling fan motor drive unit 154 operates the cooling fan 124 at the rotation speed r3 (third rotation speed) (step S251).

Here, since the second air 162 does not reach the ventilation fan 300 immediately after the operation of the heating unit 120, the ventilation efficiency does not change much even if the second airflow is assisted by the first airflow. Therefore, in order to suppress power consumption and noise, the rotation speed is set to r3, which is lower than the rotation speed r1. The rotation speed r3 is set in advance based on actual measurement results and the like.

After step S251, the main control unit 151 determines whether or not the temperature of the heated container 200 detected by the temperature detection unit 123 is equal to or higher than the reference temperature T3, which is higher than the reference temperature T2 (step S252). Here, the reference temperature T3 is a temperature at which the second airflow reaches the ventilation fan 300 after the operation of the heating unit 120 is started, for example, a temperature at which water boils, and is preset by an actual measurement result or the like.

When the main control unit 151 determines that the temperature of the container 200 to be heated is equal to or higher than the reference temperature T3 (YES in step S252), the cooling fan 124 is operated by the cooling fan motor drive unit 154 as shown in FIG. 11A. Is operated at a rotation speed r1 which is a rotation speed higher than the rotation speed r3 (step S253), and time measurement is started by the timer unit 157 (step S254). Here, the rotation speed r1 is a rotation speed required to assist the second air flow, and is set in advance based on an actual measurement result or the like.

After step S254, the main control unit 151 refers to the reference time t3 (> t2) stored in the storage unit 156, and determines whether or not the measurement time by the timer unit 157 has elapsed the reference time t3 ( Step S255). Here, the reference time t3 is the time from when the cooling fan 124 is operated at the rotation speed r1 until the second airflow stabilizes, and is set in advance based on the actual measurement results and the like.

When the main control unit 151 determines that the measurement time by the timer unit 157 has passed the reference time t3 (YES in step S255), the main control unit 151 is cooled by the cooling fan motor drive unit 154 as shown in FIG. 11A. The fan 124 is operated at a rotation speed r2, which is lower than the rotation speed r1 (step S256), and the notification unit 111 notifies that power is being saved (step S257).

After step S257, the main control unit 151 performs the processes of steps S151 to S155 shown in FIG. 8B, but the description is omitted because the processes are the same as those described in the first embodiment.

As described above, the control device 150 according to the second embodiment changes the control according to the temperature of the heated container 200 at the start of the operation of the heating unit 120. Specifically, when the temperature of the container 200 to be heated is low, the control device 150 operates the cooling fan 124 at the third rotation speed and then at the first rotation speed. Further, the control device 150 operates the cooling fan 124 at the first rotation speed without passing through the third rotation speed when the heated container 200 is at medium temperature or high temperature, but when the temperature is medium temperature, the temperature is high. The time until switching to the second rotation speed, that is, the time of the first rotation speed is longer than that at the time of.

This is because when the temperature of the container 200 to be heated is low, the time until the second airflow stabilizes becomes long, and when the temperature of the container 200 to be heated is high, the time until the second airflow stabilizes becomes short. is there. That is, the time from the start of the operation of the heating unit 120 until the second air flow stabilizes differs depending on the temperature of the container 200 to be heated at the start of the operation of the heating unit 120. Therefore, the control device 150 can suppress power consumption and noise while performing efficient ventilation by changing the control according to the temperature of the heated container 200 at the start of operation of the heating unit 120.

In the second embodiment, the rotation speeds r1 to r3 are set to fixed values, but the value is not limited to this, and at least one of the rotation speeds r1 to r3 is stored in the storage unit 156 for each of a plurality of temperature regions. The main control unit 151 may use the rotation speeds r1 to r3 stored in the temperature region corresponding to the value detected by the temperature detection unit 123. The same applies to the reference times t1 to t3.

For example, it is divided into a temperature range that does not emit water vapor and a temperature range that emits water vapor. Then, in the temperature range where water vapor is not generated, wasteful power consumption can be suppressed by lowering the rotation speed. Alternatively, it is divided into a temperature range that does not emit oil smoke and a temperature range that emits oil smoke. Then, by increasing the rotation speed in the temperature range where oil smoke is emitted, it is possible to efficiently discharge the odor and the like that enter the room to the outside.

Further, in the second embodiment, as shown in FIG. 11A, the rotation speeds r2 and r3 have the same value, but the values are not limited to the same and may be different values.

The case where the detected temperature of the heated container 200 is low is better. The reference time is set longer than when it is high.

Further, when the control device 150 receives the operation start instruction of the heating unit 120 from the operation unit 104, the temperature detection unit 123 detects the temperature of the heated container 200, and the detected temperature of the heated container 200 is the first reference value. If it is determined that the temperature is less than, the cooling fan 124 is operated at a third rotation speed lower than the first rotation speed, and then the temperature of the heated container 200 detected by the temperature detection unit 123 is higher than the first reference value. If it is determined that the temperature is equal to or higher than the reference value, the cooling fan 124 is operated at the first rotation speed.

According to the heating cooker 100 according to the second embodiment, since the rotation speed of the cooling fan 124 is switched according to the value detected by the temperature detection unit 123, the rotation speed of the cooling fan 124 is changed according to the reference time. It is possible to switch at a more optimal timing than switching between.

Further, the heating cooker 100 according to the second embodiment includes a storage unit 156 in which at least one of the first rotation speed and the third rotation speed is stored in each of a plurality of temperature regions, and the storage unit 156 is the first. When the number of rotations or the third number of rotations is stored for each of the plurality of temperature regions, the control device 150 refers to the storage unit 156 and stores the number in the temperature region corresponding to the value detected by the temperature detection unit 123. When one rotation number or the third rotation number is used and the first rotation number and the third rotation number are stored in the storage unit 156 for each of a plurality of temperature regions, the control device 150 refers to the storage unit 156 and the temperature. The first rotation number and the third rotation number stored in the temperature region corresponding to the value detected by the detection unit 123 are used.

According to the heating cooker 100 according to the second embodiment, since the first rotation speed and the third rotation speed stored in the temperature region corresponding to the value detected by the temperature detection unit 123 are used, the more optimum first rotation speed is used. The rotation speed and the third rotation speed can be used, and more optimum control of the cooling fan 124 can be performed.

Further, the heating cooker 100 according to the second embodiment includes a storage unit 156 in which the reference time is stored for each of a plurality of temperature regions, and the control device 150 refers to the storage unit 156 and the temperature detection unit 123 The reference time stored in the temperature range corresponding to the detected value is used.

According to the cooking device 100 according to the second embodiment, since the reference time stored in the temperature region corresponding to the value detected by the temperature detection unit 123 is used, a more optimum reference time can be used, and more. Optimal cooling fan 124 can be controlled.

When the operation control unit 153 receives the operation disclosure instruction of the heating unit 120 from the operation unit 104 (YES in step S301), the main control unit 151 operates the heating unit 120 with the thermal power set by the inverter circuit drive unit 155. (Step S302), it is determined whether or not the set thermal power is equal to or higher than the reference thermal power W1 (step S303).

When the main control unit 151 determines that the set thermal power is equal to or higher than the reference thermal power W1 (YES in step S303), the cooling fan 124 is rotated by the cooling fan motor drive unit 154 as shown in FIG. 13A. It is operated by the number r1 (step S304), and the time measurement is started by the timer unit 157 (step S305). Here, the rotation speed r1 is a rotation speed required to assist the second air flow, and is set in advance based on an actual measurement result or the like.

After step S305, the main control unit 151 refers to the reference time t1 stored in the storage unit 156, and determines whether or not the measurement time by the timer unit 157 has elapsed the reference time t1 (step S306). Here, the reference time t1 is the time from when the cooling fan 124 is operated at the rotation speed r1 until the second airflow stabilizes, and is set in advance based on the actual measurement results and the like.

When the main control unit 151 determines that the measurement time by the timer unit 157 has passed the reference time t1 (YES in step S306), the main control unit 151 is cooled by the cooling fan motor drive unit 154 as shown in FIG. 13 (a). The fan 124 is operated at a rotation speed r2 which is lower than the rotation speed r1 (step S307), and the notification unit 111 notifies that power saving is in progress (step S308).

After step S308, the main control unit 151 performs the processes of steps S151 to S155 shown in FIG. 8B, but the description is omitted because the processes are the same as those described in the first embodiment.

In the third embodiment, the rotation speeds r1 and r2 are set to fixed values, but the values are not limited to those, and at least one of the rotation speeds r1 and r2 is stored in the storage unit 156 for each of the plurality of thermal power regions. The main control unit 151 may use the rotation speeds r1 and r2 stored in the thermal power region corresponding to the set thermal power. The same applies to the reference times t1 and t2.

For example, it is divided into a thermal power region that does not generate much water vapor and a temperature region that emits a lot of water vapor. Then, in the temperature range where water vapor is not generated so much, wasteful power consumption can be suppressed by lowering the rotation speed. Further, in the temperature range where a large amount of water vapor is generated, by increasing the rotation speed, the water vapor and the like that can be stored in the room can be efficiently discharged to the outside.

Since the optimum value can be set more than in the case, the rotation speed of the cooling fan 124 can be switched at a more optimum timing.

Further, the heating cooker 100 according to the third embodiment includes a storage unit 156 in which at least one of the first rotation speed and the second rotation speed is stored for each of a plurality of thermal power regions, and the storage unit 156 is the first.

It is a timing chart which shows an example of the control of a fan 124.

Hereinafter, the control of the cooling fan 124 of the cooking device 100 according to the fourth embodiment will be described with reference to FIGS. 8B, 14 and 15. It is assumed that the ventilation fan 300 is operating at a set strength (for example, "medium").

When the operation control unit 153 receives the operation disclosure instruction of the heating unit 120 from the operation unit 104 (YES in step S401), the main control unit 151 operates the heating unit 120 with the thermal power set by the inverter circuit drive unit 155. (Step S402), it is determined whether or not the set thermal power is equal to or higher than the reference thermal power W1 (step S403).

When the main control unit 151 determines that the set thermal power is equal to or higher than the reference thermal power W1 (YES in step S403), the cooling fan 124 is rotated by the cooling fan motor drive unit 154 as shown in FIG. 15A. It is operated by the number r3 (step S404).

Here, since the second air 162 does not reach the ventilation fan 300 immediately after the operation of the heating unit 120, the ventilation efficiency does not change much even if the second airflow is assisted by the first airflow. Therefore, in order to suppress power consumption and noise, the rotation speed is set to r3, which is lower than the rotation speed r1 described later. The rotation speed r3 is set in advance based on actual measurement results and the like.

After step S404, the main control unit 151 determines whether or not the temperature of the container 200 to be heated is equal to or higher than the reference temperature T1 by the temperature detection unit 123 (step S405). Here, the reference temperature T1 is a temperature at which the second airflow reaches the ventilation fan 300 after the operation of the heating unit 120 is started, for example, a temperature at which water boils, and is preset by an actual measurement result or the like.

When the main control unit 151 determines that the temperature of the container 200 to be heated is equal to or higher than the reference temperature T1 (YES in step S405), the cooling fan 124 is operated by the cooling fan motor drive unit 154 as shown in FIG. 15A. Is operated at a rotation speed r1 which is a rotation speed higher than the rotation speed r3 (step S406), and time measurement is started by the timer unit 157 (step S407). Here, the rotation speed r1 is a rotation speed required to assist the second air flow, and is set in advance based on an actual measurement result or the like.

After step S407, the main control unit 151 refers to the reference time t1 stored in the storage unit 156, and determines whether or not the measurement time by the timer unit 157 has elapsed the reference time t1 (step S408).

When the main control unit 151 determines that the measurement time by the timer unit 157 has passed the reference time t1 (YES in step S408), the main control unit 151 is cooled by the cooling fan motor drive unit 154 as shown in FIG. 15 (a). The fan 124 is operated at a rotation speed r2 which is lower than the rotation speed r1 (step S409), and the notification unit 111 notifies that power saving is in progress (step S410). Here, the rotation speed r2 is the rotation speed required to maintain the stable state of the first airflow and the second airflow, and is preset by an actual measurement result or the like.

On the other hand, in step S403, when the main control unit 151 determines that the set thermal power is less than the reference thermal power W1 (NO in step S403), as shown in FIG. 15B, the cooling fan motor drive unit 154 The cooling fan 124 is operated at the rotation speed r4 (> r3) (step S411).

Here, since the second air 162 does not reach the ventilation fan 300 immediately after the operation of the heating unit 120, the ventilation efficiency does not change much even if the second airflow is assisted by the first airflow. Therefore, in order to suppress power consumption and noise, the rotation speed is set to r4, which is lower than the rotation speed r1.

Further, since the thermal power is lower than that when the reference thermal power is set to W1 or higher, the second airflow becomes weaker than when the reference thermal power is set to W1 or higher. Therefore, in order to strengthen the assist of the second airflow as compared with the case where the reference thermal power W1 or more is set, the rotation speed r4 is set to be a rotation speed higher than the rotation speed r3. The rotation speed r4 is set in advance based on actual measurement results and the like.

After step S411, the main control unit 151 determines whether or not the temperature of the container 200 to be heated is equal to or higher than the reference temperature T2 by the temperature detection unit 123 (step S412). Here, the reference temperature T2 is a temperature at which the second airflow reaches the ventilation fan 300 after the operation of the heating unit 120 is started, for example, a temperature at which water boils, and is preset by an actual measurement result or the like.

When the main control unit 151 determines that the temperature of the container 200 to be heated is equal to or higher than the reference temperature T2 (YES in step S412), the cooling fan 124 is operated by the cooling fan motor drive unit 154 as shown in FIG. 15B.

Here, the rotation speed r1 is a rotation speed required to assist the second air flow, and is set in advance based on an actual measurement result or the like.

After step S414, the main control unit 151 refers to the reference time t2 stored in the storage unit 156, and determines whether or not the measurement time by the timer unit 157 has elapsed the reference time t2 (step S415). Here, the reference time t2 is the time from when the cooling fan 124 is operated at the first rotation speed until the second airflow stabilizes, and is set in advance based on the actual measurement results and the like.

When the main control unit 151 determines that the measurement time by the timer unit 157 has passed the reference time t2 (YES in step S415), the main control unit 151 is cooled by the cooling fan motor drive unit 154 as shown in FIG. 15 (b). The fan 124 is operated at a rotation speed r2 which is lower than the rotation speed r1 (step S409), and the notification unit 111 notifies that power saving is in progress (step S410).

After step S410, the main control unit 151 performs the processes of steps S151 to S155 shown in FIG. 8B, but the description is omitted because the processes are the same as those described in the first embodiment.

In the fourth embodiment, the rotation speeds r1 to r4 are set to fixed values, but the value is not limited to this, and at least one of the rotation speeds r1 to r4 is stored in the storage unit 156 for each of a plurality of temperature regions. The main control unit 151 may use the rotation speeds r1 and r2 stored in the temperature region corresponding to the value detected by the temperature detection unit 123. The same applies to the reference times t1 and t2.

Alternatively, at least one of the rotation speeds r1 to r4 is stored in the storage unit 156 for each of the plurality of thermal power regions, and the main control unit 151 stores the rotation speeds stored in the thermal power region corresponding to the set thermal power. You may use r1 to r4. The same applies to the reference times t1 and t2.

Further, in the fourth embodiment, as shown in FIG. 15A, the rotation speeds r2 and r3 have the same value, but the values are not limited to the same and may be different values.

As described above, in the heating cooker 100 according to the fourth embodiment, the operation unit 104 includes a unit for instructing the heating power setting of the heating unit 120, and includes a temperature detecting unit 123 for detecting the temperature of the heated container 200 for control. The device 150 sets the reference time according to the thermal power set by the operation unit 104, and when the operation unit 104 receives the operation start instruction and the thermal power setting instruction of the heating unit 120, the cooling fan 124 is rotated first. Operate at a third rotation speed lower than the number, and then operate the cooling fan 124 at the first rotation speed when it is determined that the temperature of the heated container 200 detected by the temperature detection unit 123 is equal to or higher than the second reference value. The third rotation speed is set to be higher when the thermal power set by the operation unit 104 is lower than when it is higher.

According to the heating cooker 100 according to the fourth embodiment, the cooling fan 124 is first operated at a third rotation speed lower than the first rotation speed, and then is operated at the first rotation speed, and is set. The third rotation speed is set according to the generated thermal power. Therefore, more optimal control of the cooling fan 124 can be performed from immediately after the operation of the heating unit 120 to the time when the second air 162 reaches the ventilation fan 300.

Embodiment 5.
Hereinafter, the fifth embodiment of the present invention will be described, but the description of the parts overlapping with the first to fourth embodiments is omitted, and the same parts or the corresponding parts as those of the first to fourth embodiments are designated by the same reference numerals. ..

The cooking cooker 100 according to the fifth embodiment has a function of executing a plurality of automatic cooking menus, and when the automatic cooking menu is selected from the operation unit 104, the control device 150 is selected. Run the automatic cooking menu.

FIG. 16 is a flowchart showing an example of control of the cooling fan 124 of the heating cooker 100 according to the fifth embodiment of the present invention, and FIG. 17 is a flowchart for cooling the heating cooker 100 according to the fifth embodiment of the present invention. It is a timing chart which shows an example of the control of a fan 124.

Hereinafter, the control of the cooling fan 124 of the cooking device 100 according to the fifth embodiment will be described with reference to FIGS. 8B, 16 and 17. It is assumed that the ventilation fan 300 is operating at a set strength (for example, "medium").

When the operation control unit 153 receives the automatic cooking menu selection instruction from the operation unit 104 (YES in step S501), the main control unit 151 heats with the thermal power corresponding to the automatic cooking menu selected by the inverter circuit drive unit 155. The unit 120 is operated (step S502), and the cooling fan 124 is operated at the rotation speed r3 by the cooling fan motor drive unit 154 (step S503). In the fifth embodiment, it is assumed that the automatic cooking menu including the preheating step and the heat retaining step is selected.

Here, since the second air 162 does not reach the ventilation fan 300 immediately after the operation of the heating unit 120, the ventilation efficiency does not change much even if the second airflow is assisted by the first airflow. Therefore, in order to suppress power consumption and noise, the rotation speed is set to r3, which is lower than the rotation speed r1 described later. The rotation speed r3 is set in advance based on actual measurement results and the like.

After step S504, the main control unit 151 determines whether or not the temperature of the container 200 to be heated is equal to or higher than the reference temperature T1 by the temperature detection unit 123 (step S504). Here, the reference temperature T1 is a temperature at which the second airflow reaches the ventilation fan 300 after the operation of the heating unit 120 is started, for example, a temperature at which water boils, and is preset by an actual measurement result or the like.

When the main control unit 151 determines that the temperature of the container 200 to be heated is equal to or higher than the reference temperature T1 (YES in step S504), the cooling fan motor drive unit 154 rotates the cooling fan 124 at a rotation speed higher than the rotation speed r3. It is operated at the rotation speed r1 (step S505), and the time measurement is started by the timer unit 157 (step S506). Here, the rotation speed r1 is a rotation speed required to assist the second air flow, and is set in advance based on an actual measurement result or the like.

After step S506, the main control unit 151 refers to the reference time t1 stored in the storage unit 156, and determines whether or not the measurement time by the timer unit 157 has elapsed the reference time t1 (step S507). Here, the reference time t1 is the time from when the cooling fan 124 is operated at the first rotation speed until the second airflow stabilizes, and is set in advance based on actual measurement results and the like. Further, the reference time t1 differs depending on the selected automatic cooking menu.

When the main control unit 151 determines that the measurement time by the timer unit 157 has passed the reference time t1 (YES in step S507), the cooling fan motor drive unit 154 rotates the cooling fan 124 at a rotation speed lower than r1. It is operated at the rotation speed r2, which is a number (step S508), and the notification unit 111 notifies that power saving is in progress (step S509). Here, the rotation speed r2 is the rotation speed required to maintain the stable state of the first airflow and the second airflow, and is preset by an actual measurement result or the like.

After step S509, the main control unit 151 performs the processes of steps S151 to S155 shown in FIG. 8B, but the description is omitted because the processes are the same as those described in the first embodiment.

In the fifth embodiment, the rotation speeds r1 to r3 are set to fixed values, but the value is not limited to this, and at least one of the rotation speeds r1 to r3 is stored in the storage unit 156 for each of the plurality of automatic cooking menus. However, the main control unit 151 may use the rotation speeds r1 to r3 corresponding to the selected automatic cooking menu.

For example, the automatic cooking menu that uses oil (fried food, stir-fried food) and the automatic cooking menu that does not use oil are divided. And since the automatic cooking menu that does not use oil does not emit oil smoke, wasteful power consumption can be suppressed by lowering the rotation speed. Alternatively, since the automatic cooking menu that uses oil emits oily smoke, it is possible to efficiently discharge the odors that enter the room to the outside by increasing the rotation speed.

Further, in the fifth embodiment, as shown in FIG. 17, the rotation speeds r2 and r3 have the same value, but the values are not limited to the same and may be different values.

As described above, the cooking cooker 100 according to the fifth embodiment includes a storage unit 156 in which the reference time is stored for each of the plurality of automatic cooking menus, and the operation unit 104 can select the automatic cooking menu. The control device 150 refers to the storage unit 156 and uses the reference time corresponding to the automatic cooking menu selected by the operation unit 104.

According to the heating cooker 100 according to the fifth embodiment, since the reference time corresponding to the automatic cooking menu selected by the operation unit 104 is used, a more optimum reference time can be used, and a more optimum cooling fan can be used.
