FIG. 6 is an explanatory diagram showing a second embodiment of the control unit of the present invention. It is a sectional view showing a second embodiment of the range hood of the present invention.

Embodiments of the range hood and cooker of the present invention will be described based on FIG. 1. FIG. 1 is a front view schematically showing an embodiment of the range hood and cooking device of the present invention.
The range hood 1 includes a hood 2, an exhaust fan 3, a manual operation operation section 4, a control section 5, an operation status display section 6, an automatic operation switch 7, a cooking status monitoring section 8, and a notification section 9. , and a filter (not shown).
The manual operation operation section 4 and the automatic operation switch 7 are provided on the front surface 2a of the hood 2 to facilitate operation by the user. The driving status display section 6 and the notification section 9 are provided on the front surface 2a of the hood 2 so that the user can easily see them. The control unit 5 is provided inside the hood 2. Users are those who are around the range hood, such as those who cook.
A range hood 1 is installed above a cooking device 10. Note that the range hood 1 may be installed near the cooking device 10.

The hood 2 has a flow path (not shown) that is open on the lower surface.
The exhaust fan 3 includes a fan 3a and a motor 3b that rotates the fan 3a, and is provided so that the fan 3a faces the flow path of the hood 2. The exhaust fan 3 is driven by rotating the fan 3a with the motor 3b.
When the exhaust fan 3 is driven, oily smoke generated during cooking in the cooker 10 is collected in the flow path of the hood 2 and exhausted to the outside through a filter (not shown).

As shown in FIG. 2, the manual operation operation unit 4 includes an operation switch 40 and an operation status manual setting switch 41 for manually setting the operation status of the range hood. The operation switch 40 outputs a range hood operation start signal and a range hood operation stop signal to the control unit 5.
The driving status manual setting switch 41 includes a first driving status manual setting switch 41a that inputs a first driving status setting signal to the control unit 5, and a second driving status manual setting switch 41a that inputs a second driving status setting signal to the control unit 5. A switch 41b and a third driving condition manual setting switch 41c for inputting a third driving condition setting signal to the control unit 5 are provided. The operating status of the range hood is expressed as the air volume of the exhaust fan 3.
The first operating status setting signal is a signal that maximizes the air volume of the exhaust fan 3. The second operating status setting signal is a signal that sets the air volume of the exhaust fan 3 to a medium level. The third operating status setting signal is a signal that minimizes the air volume of the exhaust fan 3.
The driving status display section 6 includes a first display section 60, a second display section 61, and a third display section 62.

The first display section 60 displays a first operating condition in which the range hood is operating with the air volume of the exhaust fan 3 set to the maximum. For example, text indicating high airflow operation or sound indicating high airflow operation may be generated.
The second display section 61 displays a second operating status in which the range hood is operating with the air volume of the exhaust fan 3 set to a medium level. For example, it displays text indicating medium air volume operation or generates a sound indicating medium air volume operation.
The third display section 62 displays a third operating condition in which the range hood is operating with the air volume of the exhaust fan 3 set to the minimum. For example, text indicating low air volume operation or sound indicating low air volume operation may be displayed.

When the range hood operation start signal and the first operation status setting signal are input, the control unit 5 increases the amount of electricity supplied to the motor 3b of the exhaust fan 3 to rotate the fan 3a at high speed, thereby increasing the power supply of the exhaust fan 3. The air volume is set to the maximum, the range hood is placed in the first operating state, and the first display section 60 is displayed.
When the range hood operation start signal and the second operation status setting signal are input, the control unit 5 controls the exhaust fan 3 by setting the amount of current to the motor 3b of the exhaust fan 3 to a medium level and rotating the fan 3a at a medium speed. The range hood is set to the second operating condition with the air volume set to medium, and the second display section 61 is displayed.
When the range hood operation start signal and the third operation status setting signal are input, the control unit 5 reduces the amount of current supplied to the motor 3b of the exhaust fan 3 and rotates the fan 3a at a low speed, thereby controlling the exhaust fan 3. The air volume is set to the minimum, the range hood is placed in the third operating condition, and the third display section 62 is displayed.

When the range hood operation stop signal is input, the control unit 5 de-energizes the motor 3b, stops the exhaust fan 3, and stops the display on the display unit.
Therefore, when operating the range hood manually, the user can know the air volume of the exhaust fan 3, that is, the operating status of the range hood.
The automatic operation switch 7 inputs an automatic operation signal to the control unit 5 and sets the control unit 5 to an automatic operation mode. When no automatic operation signal is input to the control section 5, the control section 5 is in manual operation mode.
The cooking state monitoring section 8 monitors the cooking state of the cooking device 10 and inputs the cooking state of the cooking device 10 to the control section 5 . In the embodiment, the cooking state monitoring unit 8 is a smoke sensor, and the cooking state in the cooking device 10 is determined as the amount of oily smoke generated by cooking.

The control unit 5 sets the operating status of the range hood to one of a first operating status, a second operating status, and a third operating status according to the cooking status input from the cooking status monitoring unit 8 when in the automatic operation mode. When the first driving situation is set, the first display section 60 is displayed, when the second driving situation is set, the second display section 61 is displayed, and when the third driving situation is set, the third display section 62 is displayed.
Therefore, the range hood of the embodiment is a range hood with an automatic operation function, and the operating status of the range hood can be checked from the operating status display section 6 during automatic operation.

The notification unit 9 notifies the user of the change in the operating status when the control unit 5 changes the operating status of the range hood according to the cooking status monitored by the cooking status monitoring unit 8. For example, notifications can be made by playing a sound.
Therefore, during automatic operation that automatically changes the operating status of the range hood according to the cooking status, the user can know that the operating status will be changed, so the environment around the range hood can be changed to the environment that the user desires. In order to achieve this, it is easy for the user to know when to operate the manual operating status setting switch 41 to change the operating status of the range hood to an operating status different from automatic operation, and the environment around the range hood is set as desired by the user. The range hood can be made environmentally friendly.

For example, when the cooking status monitored by the cooking status monitoring unit 8 is such that the amount of oil smoke generated is low and the operating status of the range hood is automatically changed to an operating status where the air volume of the exhaust fan 3 is low, the area around the range hood The strong smell from cooking may remain in the cooking environment, creating an unpleasant environment, but the smell can be removed by manually changing the operating condition of the range hood to one in which the exhaust fan 3 has a large air volume. Strong odors can be quickly exhausted to create a pleasant environment with little odor. That is, the manual operation mode has priority over the automatic operation mode, and the operation status of the range hood can be changed by operating the operation status manual setting switch 41 when the control unit 5 is in the automatic operation mode.

As shown in FIG. 1, a smoke sensor serving as the cooking state monitoring section 8 is attached to the lower surface 2b of the hood 2 toward the cooking section 10a that generates heat of the cooking device 10. The smoke sensor detects the amount of oily smoke (mass concentration of oil particles contained in the oily smoke) generated when cooking is performed with the pot 11 etc. placed in the cooking section 10a.
The amount of oil smoke detected by the smoke sensor is input to the control section 5. In the automatic operation mode, the control unit 5 learns the cooking status of the cooking device 10 based on the input amount of oily smoke generation, and controls the motor 3b of the exhaust fan 3 so that the operating status of the range hood corresponds to the cooking status. Controls the amount of electricity and changes the operating status of the range hood.
For example, the control unit 5 is provided with a determining unit 50 that determines whether the operating status is appropriate for the monitored cooking status, and the determining unit 50 determines that the operational status is not appropriate for the monitored cooking status. At times, the control unit 5 changes the operating status of the range hood. The determination section 50 may be provided separately from the control section 5.

An example of automatic operation of a range hood will be specifically explained.
The operating status of the range hood is the air volume of the exhaust fan 3, and the operating status of the range hood is the first operating status where the air volume of the exhaust fan 3 is the maximum, and the air volume of the exhaust fan 3 is medium, similar to manual operation. The second operating condition can be changed to a third operating condition in which the air volume of the exhaust fan 3 is the minimum.
Let the cooking state in the cooker be the amount of oil smoke generated by cooking.
As shown in FIG. 3, the control unit 5 includes a first setting unit 51 that sets a range of the first cooking state (amount of oily smoke generated) that matches the first operating situation (air volume of the exhaust fan 3), and a second setting unit 51 that sets a range of the first cooking state (amount of oily smoke generated) that corresponds to the first operating state (air volume of the exhaust fan 3). A second setting section 52 sets a range of a second cooking state (amount of oil smoke generated) that matches the situation (air volume of the exhaust fan), and a third cooking state (amount of oil smoke generated) that matches the third operating situation (air volume of the exhaust fan). A third setting section 53 is provided for setting a range of the amount of generation.

An automatic operation signal is inputted from the automatic operation switch 7 to the control section 5, the control section 5 is set to automatic operation mode, and the range hood is automatically operated.
The cooking state set in the setting section (any one of the first setting section 51, second setting section 52, and third setting section 53) that corresponds to the operating condition (exhaust fan air volume) during automatic operation. The determination unit 50 compares the cooking status (amount of oily smoke generated) with the cooking status (amount of oily smoke generated) monitored by the cooking status monitoring unit 8, and determines whether the cooking status being monitored (amount of oily smoke generated) is If the cooking status is within the set cooking status (amount of oily smoke generated), it is determined that the operating status of the range hood matches the monitored cooking status, and the range hood continues to operate under the same operating status.
For example, when the range hood is operating in the first operating condition in which the exhaust fan is at its maximum air volume, the amount of oil smoke monitored by the cooking condition monitoring section 8 is the same as the cooking condition ( If the amount of oily smoke generated is within the range, it is determined that the operating status of the range hood is suitable for the monitored cooking status, and the range hood continues to be operated in the first operating status.

If the monitored cooking state (amount of oily smoke generated) is outside the range of the set cooking state (amount of oily smoke generated), the determination unit 50 determines whether the operating status of the range hood is commensurate with the cooking status being monitored. The control unit 5 changes the amount of current applied to the motor 3b of the exhaust fan 3 to change the air volume of the exhaust fan 3, and monitors the operating status of the range hood (cooking status (amount of oil smoke generated)). Change the operating conditions (exhaust fan air volume) to match that.
The control unit 5 changes the display displayed by the driving status display unit 6 by changing the driving status.
When changing the driving situation, the control unit 5 notifies the notification unit 9 of the change in the driving situation.

For example, when the range hood is operating in the first operating condition where the exhaust fan is at its maximum air volume, the cooking status (amount of oily smoke generated) monitored by the cooking status monitoring unit 8 is set in the first setting unit 51. If the cooking state (amount of oily smoke generated) falls below the range set in the cooking state (amount of oily smoke generated) and changes to a value within the range of the cooking state (amount of oily smoke generated) set in the second setting section 52, the determination section 50 determines whether the range hood is Determining that the operating status is not commensurate with the monitored cooking status, the control unit 5 reduces the amount of electricity supplied to the motor 3b of the exhaust fan 3, sets the air volume of the exhaust fan 3 to a medium air volume, and operates the range hood. Change the driving situation to the second driving situation.
Further, since the first driving situation is changed to the second driving situation, the control unit 5 stops displaying the first display unit 60 of the driving status display unit 6 and displays the second display unit 61.
Furthermore, when changing from the first driving situation to the second driving situation, the control unit 5 notifies the notification unit 9 of the change in the driving situation.

The cooking status that matches the operating status of the range hood can also be set as follows. The boundary value between the range of the cooking state (amount of oily smoke generated) set in the first setting section 51 and the range of the cooking state (amount of oily smoke generation) set in the second setting section 52 is set to a first setting value (first threshold value). ) in the first setting section 51. In other words, the minimum value of the cooking state (amount of oil smoke generated) set in the first setting section 51 becomes the maximum value of the cooking state (amount of oil smoke generation) set in the second setting section 52, and that value is the boundary value. It is.
The value of the boundary between the range of the cooking state (amount of oily smoke generated) set in the second setting section 52 and the range of the cooking state (amount of oily smoke generation) set in the third setting section 53 is set to a second setting value (second threshold value). ) in the second setting section 52. In other words, the minimum value of the cooking state (amount of oil smoke generated) set in the second setting section 52 becomes the maximum value of the cooking state (amount of oil smoke generation) set in the third setting section 52, and that value is the boundary value. It is.

When set in this way, the determination unit 50 performs monitoring by comparing the cooking status (amount of oily smoke generated) monitored by the cooking status monitoring unit 8 with the first setting value or the second setting value. It is determined whether the operating state is suitable for the current cooking state, and if the operating state is suitable, the range hood is continuously operated in that operating state. If it is not worth it, change the operating conditions of the range hood.
For example, when the range hood is being operated in the first operating state, if the monitored cooking state (amount of oily smoke generated) becomes below the first set value, the range hood is changed to the second operating state.
When the range hood is being operated in the second operating state, if the monitored cooking state (amount of oily smoke produced) becomes equal to or less than the second set value, the range hood is changed to the third operating state.

The control section 5 controls the cooking state when the cooking state (amount of oily smoke generated) monitored by the cooking state monitoring section 8 falls outside the range of the cooking state set according to the operating status of the range hood, or when the set value is changed. Even if the operating status of the range hood is changed after a certain period of time, the notification unit 9 immediately notifies you of a change in the operating status when it exceeds the operating status, that is, when the operating status no longer matches the operating status. good.
Also, based on the amount of change per unit time in the cooking state (amount of oily smoke generated) monitored by the cooking state monitoring unit 8, the cooking state (amount of oily smoke generated) being monitored is determined to be the same as the cooking state (amount of oily smoke generated). The time when the amount of occurrence (amount of generated electricity) will be outside the range or the time when the set value will be exceeded is predicted, and the notification unit 7 notifies you of a change in the operating situation a certain period of time before the predicted time, and then the predicted time is reached. The operating status of the range hood may be changed from time to time.
That is, the control unit 5 may notify the change in the operating condition a certain period of time before changing the operating condition (air volume of the exhaust fan) of the range hood.

By notifying the user of changes in the operating status a certain amount of time before changing the operating status of the range hood (exhaust fan air volume), the user can be notified of changes in the operating status a certain amount of time before the operating status changes. To enable a user to quickly change the operating status of a range hood and to select an operating status before the operating status is changed.
Further, as in the second embodiment of the control unit shown in FIG. By operating the stop switch 54 and inputting a change stop signal to the control unit 5 within a certain period of time after being notified of a change in the operating status of the hood and before changing the operating status, the control unit 5 will stop the operation after a certain period of time. You can choose to stop changing the situation. Note that a change stop signal can be input to the control unit 5 by continuously operating the automatic operation switch 7 for a long time. In other words, the automatic operation switch 7 can also be used as a change/cancel operation section. Further, another switch used for operating the range hood, such as a light switch that turns on and off the light attached to the hood 2, may also serve as the change/cancel operation section.
This can prevent the area around the range hood from becoming an environment that the user does not want.

After stopping changing the operating status of the range hood, the control unit 5 can continue the operating status at the time when the change in the operating status was notified.
The control unit 5 can change the operating status of the range hood to one that matches the cooking status monitored by the cooking status monitoring unit 8 after a predetermined period of time has passed since the change in the operating status of the range hood is stopped. The predetermined time may be set in the control unit 5 in advance, or may be set in the control unit 5 when notifying a change in the driving situation. By doing this, after a predetermined period of time has passed since the user manually changed the operating state to the one desired by the user, the operating state of the range hood becomes an operating state that matches the cooking state monitored by the cooking state monitoring unit 8. .

The notification unit 9 notifies the driver of changes in driving conditions using sounds such as voice and music.
Therefore, the user can know that the operating situation has changed by being near the range hood without visually checking the notification unit 9.
The notification unit 9 can notify the user of the change in the driving situation using a sound that corresponds to the changed driving situation.
For example, when the air volume of the exhaust fan 3 is changed to the first operating condition where it is maximum, a "beep" sound is emitted.
When the air volume of the exhaust fan 3 is changed to the second operating state where the air volume is medium, a "beep" sound is emitted.
When the air volume of the exhaust fan 3 is changed to the third operating condition where it is minimum, a "beep" sound is emitted.
Therefore, the driving situation after the change can be known by the number of beeps.

The notification unit 9 does not display the changed operating condition by the number of beeps, but if the changed operating condition causes the air volume of the exhaust fan 3 to increase more than the pre-change operating condition, A beep sound is sounded, and if the air volume of the exhaust fan 3 after the change is lower than the operating state before the change, the beep sound is emitted, and the number of beeps is determined by the number of beeps. It may also be possible to display whether the operating situation has changed to one where the air volume of the exhaust fan 3 increases or whether the operating situation has changed to one where the air volume of the exhaust fan 3 decreases.

The cooking state monitoring unit 8 is not limited to a smoke sensor, and may include a pot bottom temperature sensor installed in the cooking unit 10a of the cooking device 10 to measure the temperature of the bottom of the pot 11, and a pot bottom temperature sensor installed in the lower surface 2b of the hood 2 to measure the temperature at the bottom of the cooking unit 11. A temperature sensor that measures the temperature of food, a sound sensor that monitors the sound generated during cooking, a color sensor that monitors the color of the food being cooked, a cooking device operating state sensor that causes the cooking device 10 itself to generate a signal depending on the cooking state, etc. Any one or a combination of these can be used.
When the cooking state monitoring unit 8 is a smoke sensor, the amount of oil smoke generated is the cooking state, but when it is other than a smoke sensor, the cooking state is determined by the state monitored by the cooking state monitoring unit 8, such as a temperature sensor. In the case of a sound sensor, the type of sound, in the case of a color sensor, the type of color, brightness, etc. are the cooking status.

Although the operating status of the range hood was taken as the air volume of the exhaust fan 3, in the case of a range hood with a rotating filter, the rotational speed of the filter can be used as the operating status of the range hood.
For example, as shown in FIG. 4, a range hood is provided in which a filter 20 is rotatably provided in a hood 2, and by rotating the filter 20 with a motor 21, oil and fat from oil smoke is removed by adhering to the filter 20. In this case, the rotation speed of the filter 20 is set to the operating state of the range hood, and the amount of current supplied to the motor 21 is changed to change the rotation speed of the filter 20 to change the operating state.
