[0007] In the range hood of the present invention, the notification section may be a light-emitting section, and the control section may control the light emission mode of the light-emitting section to issue a predetermined notification. With this range hood, even someone who is some distance away from the range hood, such as in the living room, can visually see the light emitted from the light-emitting part and realize that the range hood has been remotely operated. This is effective when the area around the range hood is dark, and is even more effective if the light emitting part emits light intermittently (blinks).

[0008] In the range hood of the present invention, the notification section may be a sound output section, and the control section may control the sound output mode of the sound output section to issue a predetermined notification. With this range hood, even people who are some distance away from the range hood can hear the sound and notice that the range hood has been remotely operated. Moreover, because they listen to the sound, they can notice even in cases where it would be difficult to notice just by looking at the light emitted by the light-emitting part. This is effective even when the area around the range hood is dark, and is even more effective if the sound output is in the form of a voice such as a melody.

[0009] In the range hood of the present invention, the notification unit may be a display unit, and the control unit may control the display mode of the display unit to issue a predetermined notification. With this range hood, a user can notice that the range hood has been remotely operated by looking at the display on the display unit, and since the user can be notified visually, the user can notice even if it is noisy around the range hood.

[0010] In the range hood of the present invention, the notification unit includes a light-emitting unit, a sound output unit, and a display unit, and the control unit can be a range hood that issues a predetermined notification by combining any of the light-emitting mode of the light-emitting unit, the sound-producing mode of the sound output unit, and the display mode of the display unit. According to this range hood, it is possible to select the combination of notification modes that is most noticeable depending on the situation.

[0011] In the range hood of the present invention, the control unit can be a range hood that, when it receives a control command from the mobile terminal, controls the notification unit to make a specified notification, and controls the communication unit to send a notification to the mobile terminal that the control command has been received. With this range hood, a person who remotely controls the range hood using a mobile terminal can know whether their instructions have been reflected in the control of the range hood.

[0012] In the range hood of the present invention, the light emission mode of the light emitting part may be the light color and / or blinking of the light emitting part. This range hood can produce a light emission that is easily noticeable by people. In the range hood of the present invention, the sound output from the sound output unit may be any one of volume, frequency, and time change, or a combination of these. According to this range hood, by notifying the user with a sound volume, melody, or other sound format, it is possible to create a sound format that is easy for people to notice.

[0013] In the range hood of the present invention, the display mode of the display unit is the range hood which is identification information showing the contents of the remote operation command. With this range hood, not only is it possible to know that a remote control command has been issued, but also the content of that command.

[0014] In the range hood of the present invention, the range hood is provided with an information collection unit that is provided in the range hood and collects information about the surroundings, and the control unit controls the alarm unit based on the information about the surroundings collected by the information collection unit to issue a predetermined alarm in a manner corresponding to the information about the surroundings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] An embodiment of the range hood of the present invention will be described. The configuration of the range hood of the present invention will be described with reference to Fig. 1. Fig. 1 is a schematic explanatory diagram of the configuration of the range hood of the present invention, a cooking appliance, and a mobile terminal. As shown in FIG. 1, a range hood 10 of the present invention is installed near a cooking appliance 20 . Range hood 10 includes a blower 11, a lighting unit 12, an operation unit 13, a control unit 14, a communication unit 15, a notification unit 16, an information collection unit 17, and a cooking status determination unit 18. The notification unit 16 includes a light emitting unit 16a, a sound output unit 16b, and a display unit 16c.

[0030] The cooking device 20 includes a heating section 21, a cooking device control section 22, a cooking device operation section 23, a cooking device communication section 24, and a temperature detection section 25 on the cooking side. Cooker operation unit 23 is operated by a human and sends heating start commands, heating stop commands, and heating intensity adjustment commands to cooker control unit 22, and cooker control unit 22 starts heating unit 21, stops heating, and adjusts the heating intensity. The temperature detection unit 22 on the cooking appliance side detects the temperature of the top plate of the heating unit 21 and the temperature of the bottom of the cooking vessel, and can detect the temperature of the cooking vessel etc. being cooked in the cooking appliance 20, and sends the detected temperature to the cooking appliance control unit 22. The cooking appliance communication unit 24 and the communication unit 15 of the range hood 10 are connected to each other wirelessly (Bluetooth (registered trademark)) or via wires so that they can communicate with each other.

[0031] The range hood 10 is capable of communicating with the mobile terminal 30. The mobile terminal 30 is equipped with a display unit 31 which is a first notification unit and displays characters, text, etc., a speaker 32 which is a second notification unit and emits voice, sound, etc., a mobile terminal control unit 33, a mobile terminal operation unit 34, and a mobile terminal communication unit 35. The communication unit 15 of the range hood 10 and the mobile terminal communication unit 35 are wirelessly connected to be able to communicate with each other, and the range hood 20 and the mobile terminal 30 are wirelessly connected to be able to communicate with each other. For example, the communication unit 15 of the range hood 10 is wirelessly (WiFi) connected to a network 2 such as the Internet via a router 1, the mobile terminal communication unit 35 is wirelessly (WiFi) connected to the network 2, and the mobile terminal 30 is wirelessly connected to the network 2 via the router 1 and the range hood 10 to be able to communicate with each other.

[0032] The mobile terminal operation unit 34 may be an independent operation unit on the mobile terminal 30, or may be an operation unit that operates a screen like a smartphone. The mobile terminal 30 is an information device that can be easily carried by a person, such as a mobile phone such as a smartphone, a small personal computer such as a tablet, or a smartwatch.

[0033] The operation control of the range hood 10 will now be described. Operation control by the operation unit 13 is as follows. The operating unit 13 of the range hood 10 is operated by a person and transmits control commands to the control unit 14 to control the operation of the range hood 10, such as a control command to start the operation of the blower 21, a control command to stop the operation, a control command to adjust the airflow, a control command to turn on the lighting unit 22, and a control command to turn off the lighting unit 22. Based on the transmitted control command, the control unit 14 changes the air volume of the blower 21, turns on the light 22, turns off the light 22, and controls the notification unit 16 to give a predetermined notification. That is, the control unit 14 controls the operation of the range hood 10 based on a control command sent from the operation unit 13, and also controls the notification unit 16 to give a predetermined notification.

[0034] The operation control by remote control is as follows. By operating the mobile terminal operation unit 34, control commands such as a control command to start operation of the blower 21, a control command to stop operation, a control command to change the airflow rate, a control command to turn on the lighting unit 22, and a control command to turn off the lighting unit 22 are transmitted to the mobile terminal control unit 33. The control commands are transmitted to the control unit 14 via the mobile terminal communication unit 35, the router 1, and the communication unit 15. Based on the control command transmitted from the mobile terminal 30, the control unit 14 starts or stops the operation of the blower 21, adjusts the air volume of the blower 21, turns on or off the light 22, and controls the notification unit 16 to give a predetermined notification. The manner of the predetermined notification at this time differs from the manner of the predetermined notification when the operation unit 13 is operated to control the operation of the range hood 10. In other words, the control unit 14 controls the operation of the range hood 10 based on a control command transmitted from the mobile terminal 30, and also controls the notification unit 16 to give a predetermined notification in a manner different from that when the operation unit 13 is operated.

[0035] In this way, a predetermined notification is given when the operation of range hood 10 is controlled by operating operation unit 13, and a predetermined notification is given when the operation of range hood 10 is controlled by operating mobile terminal 30. Since the manner of the predetermined notification is different, it is possible to know whether the operation of range hood 10 is controlled by operating operation unit 13 or by remote control.

[0036] When a control command is sent from the mobile terminal 30, the control unit 14 controls the operation of the range hood 10 based on the control command, and controls the communication unit 15 to send a notification to the mobile terminal 30 that the operation control based on the control command has been performed. The mobile terminal 30 notifies, via the display unit 31 and / or the speaker 32, that the operation of the range hood 10 has been controlled based on the control command. For example, when a control command to change the airflow of blower 21 is sent from mobile terminal 30, a notification that the airflow of blower 21 has been changed is sent from communication unit 15 of range hood 10 to mobile terminal control unit 33, and mobile terminal 33 controls display unit 31 and / or speaker 32 to notify that the airflow of blower 21 has been changed.

[0037] If the control unit 14 has this configuration, even if a person who remotely operates the range hood 10 by operating the mobile terminal 30 has difficulty noticing the notification from the notification unit 16 of the range hood 10, the person can know through the mobile terminal 30 whether the range hood 10 has been operated as remotely controlled.

[0038] The configuration of the notification unit 16 will be described. The notification unit 16 shown in FIG. 1 has a light emitting unit 16a, a sound output unit 16b, and a display unit 16c, but the notification unit 16 can have the following configuration. The notification unit 16 is a light-emitting unit 16a, and the control unit 14 controls the light emission mode of the light-emitting unit 16a to perform a predetermined notification. According to this configuration, even a person who is in a place some distance away from range hood 10, such as in a living room, can visually see the light emitted from light-emitting portion 16a and realize that range hood 10 has been remotely operated. This is effective when the area around the range hood 10 is dark, and is even more effective if the light emitting portion 16a emits light intermittently (blinks). The light emitting manner of the light emitting unit 16a is the adjustment of the light color and / or blinking of the light emitting unit 16a, and the amount of light or illuminance. This makes it possible to generate a light emission pattern that is easily noticeable by people.

[0039] The notification unit 16 is a sound output unit 16b, and the control unit 14 controls the sound output mode of the sound output unit 16b to give a predetermined notification. With this configuration, even a person who is some distance away from the range hood 10 can hear the sound and notice that the range hood 10 has been remotely operated. Moreover, because the person hears the sound, they can notice even in cases where it would be difficult to notice just by the light emitted by the light-emitting portion 16a. This is effective even when the area around the range hood is dark, and is even more effective if the sound output is in the form of a voice such as a melody. The sound output mode of the sound output unit 16b is any one of volume, frequency, and time change, or a combination of these. According to this, by notifying with a sound volume, melody, or other sound mode, it is possible to generate a sound mode that is easy for people to notice.

[0040] The notification unit 16 is a display unit 16c, and the control unit 14 controls the display mode of the display unit 16c to perform a predetermined notification. According to this configuration, the user can notice that the range hood 10 has been remotely operated by looking at the display on the display unit 16c, and since the user can be informed visually of the notification, the user can notice even if it is noisy around the range hood 10. The display form of the display unit 16c is identification information indicating the contents of the remote control command, for example, the contents of the remote control command are displayed in text or pictures. This allows the user to know not only that a remote control command has been issued, but also the content of that command.

[0041] The notification unit 16 is equipped with a light-emitting unit 16a, a sound output unit 16b, and a display unit 16c, and the control unit 14 is configured to make a predetermined notification by combining any of the light-emitting state of the light-emitting unit 16a, the sound-producing state of the sound output unit 16b, and the display state of the display unit 16c. According to this configuration, it is possible to select the most noticeable combination of notification modes depending on the situation.

[0042] An embodiment of the operating section 13 of the range hood 10 will be described below. Fig. 2 is an external perspective view of the range hood, and Fig. 3 is an enlarged front view of the operating section. As shown in Fig. 2, range hood 10 has a fan box 41 and a fascia board 42 on the upper surface of hood 40. An LED light (not shown) is provided on the lower surface of hood 40, constituting lighting unit 12. This lighting unit 12 also serves as light-emitting unit 16a of notification unit 16. However, this is not limited to the above, and light-emitting unit 16a may be provided separately from lighting unit 12. An operating unit 13 is provided on a front surface 40a of the hood 40. The front surface 40a of the hood 40 is the surface facing the cook. This operating unit 13 (switch LED) also functions as the light-emitting unit 16a of the notification unit 16.

[0043] As shown in FIG. 3, the operation unit 13 is provided with a power switch 43, a low switch 44, a medium switch 45, a high switch 46, a lighting switch 47, a display unit 48, and a sound output unit 49. By operating each of the switches 43 , 44 , 45 , 46 , and 47 , a control command is input to the control unit 14 . A display unit 48 and a sound output unit 49 perform display and sound output in response to instructions from the control unit 14 . The display unit 48 displays various information such as the operation details of the range hood 10 and the timer time, and can be used as the display unit 16c of the notification unit 16. The sound output unit 49 outputs various information such as the operation details of the range hood 10 and the timer time in the form of sound effects or voice, and can be used as the sound output unit 16 b of the notification unit 16 .

[0044] The operation control of the range hood 10 by the operating unit 13 will now be described. When the power switch 42 is turned ON and any one of the low switch 43, medium switch 44, and high switch 45 is operated, a control command to start operation at low airflow, medium airflow, or high airflow is sent to the control unit 14, and the operated switch lights up. As a result, the blower 11 starts operating at a low, medium or high airflow rate. In this state, when the power switch 42 is operated again, the blower 11 stops.

[0045] When any one of the weak switch 44, medium switch 45, and strong switch 46 is operated (when the blower 11 is operating at a weak, medium, or strong airflow rate), if a switch other than the first one operated is operated, the first one operated is turned off and the second one operated is turned on, and a control command for changing the airflow rate is sent to the control unit 14 to change and control the airflow rate of the blower 11. For example, when the strong switch 46 is operated while the weak switch 44 is operated, a strong operation control command to set the strong airflow rate is sent to the control unit 14, the airflow rate of the blower 11 is changed to the strong airflow rate, the light is turned on, and the weak switch 44 is turned off.

[0046] When the lighting switch 47 is operated, a lighting control command is sent to the control unit 14 to turn on the lighting unit 12 and the lighting switch 47 is also turned on. When the lighting switch 47 is operated again, a turn-off control command is sent to the control unit 14 to turn off the lighting unit 12 and the lighting switch 47. That is, each of the switches 43, 44, 45, 46, and 47 has a built-in light and a light-transmitting portion on its surface, and serves as a switch for turning the light on and off. With the operation unit 13 having this configuration, the lighting of each switch can serve as a predetermined notification when the operation of the range hood 10 is controlled by operating the operation unit 13. Without being limited thereto, it is also possible to configure the notification unit 16 to give a predetermined notification when the operation of the range hood 10 is controlled by operating the operation unit 13 .

[0047] The information collecting unit 17 collects information about the surroundings of the range hood 10 . The information regarding the surroundings of the range hood 10 includes information regarding whether cooking is being performed using the cooking appliance 20, the temperature of the food being cooked, information regarding whether or not there are people near the range hood 10, the brightness of the surroundings of the range hood 10, the volume of noise around the range hood 10, etc. To obtain information on whether cooking is being performed, a temperature sensor 50, a gas sensor 51, and an illuminance sensor 52 are provided. The temperature sensor 50 is an infrared temperature sensor, and detects the temperature of the top surface of the cooking device 20. If the detected temperature is higher than a predetermined temperature, it is determined that cooking is being performed, and if it is lower, it is determined that cooking is not being performed. Gas sensor 51 detects gas generated during cooking to determine whether cooking is being performed. The method of acquiring information on whether cooking is being performed is not limited to this, and cooking image information may be acquired by a camera.

[0048] Whether cooking is taking place or not is judged based on the brightness in the vicinity of the cooking device 20 detected by the illuminance sensor 52. This is not limiting, and the determination can be made based on the heating start operation and heating stop operation of the cooking device 20. For example, the heating start operation of the cooking device operation unit 23 is detected to determine whether cooking is being performed. Also, it is possible to determine whether cooking is being performed based on the temperature detected by temperature detection unit 25 of cooking appliance 20. In addition, it is possible to determine whether cooking is being performed by various other means. The temperature of the food being cooked can be detected by the temperature sensor 50.

[0049] A human presence sensor 53 is provided to obtain information on the presence or absence of people. The human presence sensor 53 detects people in the vicinity of the range hood 10, and when it detects a person, it determines that there is a person (presence), and when it does not detect a person, it determines that there is no person (absence). The position of the person carrying the mobile terminal 30 is detected from the position information using the GPS of the mobile terminal 30, and if the person is far away from the range hood 10, it is determined that there is no person (absent), and if the person is close to the range hood 10, it is determined that there is a person (present). The brightness around the range hood 10 can be detected by an illuminance sensor 52. The range hood 10 is provided with a sound collector (sound sensor) 54 for obtaining information on the volume of sound around the range hood 10. The information collecting unit 17 is equipped with a camera 55. Information on the presence or absence of people can also be obtained from this camera 55.

[0050] The cooking status determination unit 18 determines the cooking status of the user based on the surrounding information collected by the information collection unit 17 and / or information from the mobile terminal 30. The cooking situation of the user is determined by taking into consideration the situation of the user (whether or not the user is near the range hood 10), the situation around the range hood 10, and information from the mobile terminal 30.

[0051] The control unit 14 stores a plurality of notification modes, selects a notification mode based on the information collected by the information collection unit 17 and the user's cooking status determined by the cooking status determination unit 18, and controls the notification unit 16 to make a specified notification. This operation will be explained based on the control flow chart shown in FIG. When the control unit 14 receives a control command from the mobile terminal 30 and a control command from the operation unit 13 (step 100), the control of the range hood 10 is changed based on the control command (step 101). If the control command is from the mobile terminal 30 (YES in step 102), the control status of the range hood 10 is confirmed (step 103), and then the surrounding information collected by the information collecting unit 17 is confirmed (step 104), and further the command information and position information received from the mobile terminal 30 are confirmed (step 105), and a notification mode according to the user's cooking status is selected (step 106).

[0052] A command is sent to the notification unit 16 to control the notification mode so as to implement the selected notification mode (step 107). If notification to the mobile terminal 30 is necessary (YES in step 108), the communication unit 15 is instructed to transmit control information to the mobile terminal 30 (step 109). If the control command is not from the mobile terminal 30 (NO in step 102), the notification mode is determined according to the contents of the control command (step 110), and the notification unit 16 is instructed to perform control (step 107).

[0053] When an operation command is received from the mobile terminal 30, the notification unit 16 is controlled to issue a predetermined notification based on the information about the surroundings of the range hood 10 collected by the information collection unit 17, so that the predetermined notification is made in a manner that corresponds to the surrounding conditions of the range hood 10, and therefore it is possible to notify the recipient of the notification that a control command has been input by remote operation in a manner that is easily noticeable to the recipient, in accordance with the surrounding conditions. This allows the recipient of the notification (the user cooking or the user who sent the control command) to know that the operation of the range hood 10 has been controlled. In addition, by selecting the notification mode taking into consideration the judgment of the cooking status judgment unit 18, it is possible to notify the recipient of the input of a control command by remote control in a manner that is easily noticeable according to the cooking status. This allows even a user who is cooking or a user who is in a location away from the cooking space in the house to know that the operation of the range hood 10 has been controlled by remote control. For example, when the cooking status determined by the cooking status determination unit 18 from the information collected by the information collection unit 17 is that cooking is in progress, if a control command is transmitted from the mobile terminal 30, a sound is output from the sound output unit 16b. As a result, even if cooking is being done in a bright environment, the user can be informed by the sound that a control command has been transmitted from the mobile terminal 30. In other words, even if the light-emitting unit 16a emits light in a bright environment, the user will not easily notice it.

[0054] Furthermore, when controlling notification unit 16 to give a notification, if a control command to reduce the air volume of blower 11 is received from mobile terminal 30 when cooking status determined by cooking status determination unit 18 is cooking, control unit 14 controls notification unit 16 to give a predetermined notification that is highly discernible, i.e., extremely easy to notice. Note that reducing the air volume includes setting the air volume to zero (stopping the blower). With this configuration, the user who is cooking can clearly know that the air volume of blower 11 is being controlled to be reduced by remote control, which is preferable from the standpoint of safety. In other words, since a decrease in the airflow rate of blower 11 during cooking can be dangerous, this is preferable from the standpoint of safety as it can alert the user to the danger. The notification mode at this time may be a combination of red light from the light-emitting unit 16a and a loud sound from the sound output unit 16b, or a combination of red light from the light-emitting unit 16a, a loud sound from the sound output unit 16b, and a text display indicating a decrease in airflow on the display unit 16c.

[0055] It is possible to give a different notification mode depending on whether or not there is a person near the range hood 10. For example, if a control command is transmitted from the mobile terminal 30 when the human presence sensor 53 has not detected a person and therefore has determined that there is no person near the range hood 10, an alarm will be emitted in a manner that is easy to notice even from a location far away from the range hood 10 (such as a loud sound or a strong flashing light), and if a control command is transmitted from the mobile terminal 30 when the human presence sensor 53 has detected a person and therefore has determined that there is a person near the range hood 10, an alarm will be emitted in a manner that will not cause discomfort to people near the range hood 10 (such as a soft sound or a weak light).

[0056] That is, a notification is given in a manner that corresponds to whether or not a person is present near the range hood 10. With this configuration, for example, even a person far away from the range hood 10 can know that the range hood 10 has been operated by remote control, and it is possible to prevent a person near the range hood 10 from feeling uncomfortable due to the notification.

[0057] A user may leave the range hood 10 for a short time, such as when refilling ingredients during cooking or when the doorbell rings. In this case, it is meaningless for the notification unit 16 to notify if the range hood 10 is operated by remote control. In order to solve this problem, the control unit 14 has the following configuration. When the human sensor 53 does not detect a human and transmits information indicating that no one is present near the range hood 10, the notification from the notification unit 16 is temporarily suspended when a control command is transmitted from the mobile terminal 30. Thereafter, when the human presence sensor 53 detects a person and transmits information indicating that a person is present near the range hood 10, the notification unit 16 is controlled to give a predetermined notification. With this configuration, unnecessary notifications can be prevented, and a user who temporarily leaves range hood 10 can know that range hood 10 has been operated by remote control when he or she returns to range hood 10.

[0058] The range hood 10 of the present invention is provided with a timer capable of setting and displaying a time such as a kitchen timer. The timer time can be remotely set using the mobile terminal 30. When the control unit 14 receives a control command for setting the time of the timer from the mobile terminal 30, it changes the time setting of the timer and displays the changed time on the display unit 48. Thereafter, the control unit 14 controls the notification unit 16 in accordance with the elapsed time of the timer to provide a notification in accordance with the elapsed time. For example, the time set by the timer is displayed in numbers on the display unit 16c, and the numbers are changed to smaller numbers according to the elapsed time. Also, the color density (or color temperature or color) of the lighting unit 12 is changed according to the elapsed time. Alternatively, the display unit 16c may display a color (in the form of a colored bar graph) with a length corresponding to the set time, and the length of the color display may be shortened according to the elapsed time. Alternatively, the color shade may be changed instead of the length of the color display.

[0059] With this configuration, a user who is away from the range hood 10 can know the remaining time on the timer, and can know the remaining operating time of the range hood 10 if the operating time of the range hood 10 is set using the timer. Therefore, the user can set the timer to a longer time as needed to keep the range hood 10 operating for a period of time equal to or longer than the remaining operating time.

[0060] A specific example of a notification given when the operation unit 13 is operated will be described with reference to the table shown in FIG. First concrete example ((1) in the table of Figure 5). As a control command, an example is shown in which, when the weak switch 44 is operated to operate the blower 11 at a weak airflow rate, the strong switch 46 is operated to change the airflow rate of the blower 11 to a strong airflow rate. The low switch 44 is no longer illuminated, and the high switch 46 is illuminated. The illumination unit 12 remains unchanged. The sound output unit 49 emits a "beep beep" buzzer sound. The display unit 49 remains unchanged. Second concrete example ((2) in the table of Figure 5). When the lighting switch 47 is operated to control the lighting unit 12, the lighting switch 47 lights up, the airflow change switch, the lighting unit 12, and the display unit 49 remain unchanged, and the sound output unit 49 emits a beep sound. That is, when the airflow change switch or the lighting switch is operated by direct operation, the corresponding switch lights up and a "beep beep" buzzer sound is emitted from the sound output unit 49. As a predetermined notification by direct operation, notification by the light-emitting unit 16b (lighting unit 12) or the display unit 48 is not performed.

[0061] A specific example of a notification when a control command is received from the mobile terminal 30 will be described with reference to the table shown in FIG. 6 (this example is a notification that takes into consideration the surrounding information, but the specific notification shown in FIG. 6 may be made when a control command is received from the mobile terminal 30 regardless of the surrounding information). The third specific example ((1) in the table of Figure 6). The control command from the mobile terminal 30 is to change the air volume of the blower 11. The surrounding information is that the sound is about 60db, which is somewhat loud, and the brightness is about 5000K daylight white. The notification is made by turning on the air volume change switch, flashing the lighting unit 12, increasing the volume of the sound output unit 49 with a "beep beep" buzzer, and showing the contents of the control command on the display unit 49.

[0062] Fourth concrete example ((2) in the table of Figure 6). The control command from the mobile terminal 30 is to change the lighting. The surrounding information is that the sound is about 60db, which is somewhat loud, and the brightness is about 5000K daylight white. The notification is made by turning on the air volume change switch, flashing the lighting unit 12, increasing the volume of the sound output unit 49 with a "beep beep" buzzer, and showing the contents of the control command on the display unit 49. The first and second specific examples are examples of a predetermined notification when a control command is received by a direct operation, and the third and fourth specific examples are examples of a predetermined notification when a control command is received from the mobile terminal 30. Even if the content of the control command is the same (for example, change in air volume), the predetermined notification is performed in a different manner (sound volume or whether or not the lights are turned on and off). This allows the recipient of the notification to easily notice the input of the control command from the mobile terminal 30.

[0063] A specific example of a notification when a control command is received from the mobile terminal 30 and a notice to the mobile terminal 30 will be described with reference to the table shown in Fig. 7. (This example is for making a predetermined notification taking into account surrounding information). Fifth concrete example ((1) in the table of Figure 7). The control command from the mobile terminal 30 is to change the air volume of the blower 11. The surrounding information is that the sound is about 60db, which is somewhat loud, and the brightness is about 5000K daylight white. The notification is as follows: the air volume switch is lit, the lighting unit 12 remains unchanged, the sound output unit 49 produces a "beep beep" buzzer sound, and the display unit 49 remains unchanged. The notification to the mobile terminal 30 notifies the control command reflection status (that the air volume of the blower 11 has been changed).

[0064] The sixth concrete example ((2) in the table of FIG. 7). The control command from the mobile terminal 30 is to change the lighting. The surrounding information is that the sound is about 60db, which is somewhat loud, and the brightness is about 5000K daylight white. The notification is as follows: the lighting switch turns on, the lighting unit 12 remains unchanged (lighting changes are made based on control commands, but the lighting unit 12 is not changed for the specified notification), the sound output unit 49 produces a "beep beep" buzzer sound, and the display unit 49 remains unchanged. The notification to the mobile terminal 30 notifies the control command reflection status (that the lighting has been changed). The fifth and sixth specific examples are examples of a predetermined notification when a control command is received from the mobile terminal 30. In these examples, a notification is sent to the mobile terminal 30 that sent the control command, taking into consideration surrounding information (the cooking space is somewhat noisy and bright). When the cooking space is somewhat noisy and bright, even if a predetermined notification is sent by the notification unit provided in the range hood 10, for example, the sender of the control command who is in a place away from the kitchen (the living room or a room in the house) may not be able to confirm the content of the notification. Even in such a case, the user can check the control command reflection status on the mobile terminal 30, and can therefore confirm that the range hood 10 is operating according to his or her instructions without seeing the predetermined notification from the range hood.

[0065] A specific example of a notification when a control command is received from the mobile terminal 30 and a notice to the mobile terminal 30 will be described with reference to the table shown in FIG. 8 (this example is one in which a predetermined notification is made taking into account information about the surroundings and information about the mobile terminal 30). Seventh concrete example ((1) in the table of Figure 8). Blower 11 operates at low airflow. The surrounding information is that a command to start heating has been detected from the cooking device operation unit 23, the temperature detected by the temperature sensor 50 is 65°C, the human presence sensor 53 has not detected any people and no one is present, the sound detection value of the sound collector 54 is around 55db which is somewhat noisy, and the detection value of the illuminance sensor 52 is around 2000K which is somewhat dark.

[0066] From this information, the control unit 14 determines that the cooking device 20 is in a heating state, the temperature of the food being cooked is 65° C., it is dark, and the cook is not near the range hood. The information from the mobile terminal 30 includes an operation control command for low airflow, location information, and in-home access point information. From the access point information, it is determined that the control command is from inside the home. The control unit 14, based on the access point information, determines that the commander is inside the home, and because the stove signal is ON, infers that the commander is a cook and is not far from the kitchen in the home, or that he or she will be away from the kitchen for a short time, and determines that there is no need to notify the mobile terminal 30. The control unit 14 selects the notification mode that is most suitable for the determined situation from among a plurality of notification modes stored therein, and controls the notification unit 16 to issue a notification. The notification mode in this situation is that the lighting unit 12 flashes twice every minute, the sound output unit 49 outputs a "beep beep" buzzer sound at a normal volume, and the display unit 48 remains unchanged. No notification is sent to the mobile terminal 30. In other words, control is performed on the assumption that a specified notification at regular intervals by the lighting unit 12 is effective.

[0067] The situation at this time is as follows: The cook leaves the kitchen while cooking at a low temperature and moves to the living room or the like in the house, and since the smell in the living room no longer bothers him / her, he / she issues an operation control command for a weak airflow rate from the living room using the mobile terminal 30. In this case, since the kitchen space is dark, it is determined that the most appropriate notification is by lighting unit 12, and lighting unit 12 is made to flash twice every minute. This allows the cook in the living room to know that blower 11 is operating according to the operation control command.

[0068] Eighth specific example ((2) in the table of Figure 8). Blower 11 is not in operation and the airflow is OFF. The surrounding information is as follows: no instruction to start heating was detected from the cooking device operation unit 23, the temperature detected by the temperature sensor 50 was 80°C, the human presence sensor 53 did not detect any people and no one was present, the sound detection value of the sound collector 54 was about 55db and somewhat noisy, and the detection value of the illuminance sensor 52 was about 5000K and daylight white.

[0069] From this information, the control unit 14 determines that the cooking device 20 is in a heating off state, the temperature of the food being cooked is 80° C., it is bright outside, and the cook is not near the range hood. The information of the mobile terminal 30 includes an operation control command for low airflow, position information, and acceleration sensor information. The control unit 14 calculates the distance between the range hood 10 and the mobile terminal 30 from the location information, and determines from that distance that it is an in-home access point (the location where the operation was performed is inside the home), and determines from the acceleration sensor information that the cook is moving. The control unit 14 selects the notification mode that is most suitable for the determined situation from among a plurality of notification modes stored therein, and controls the notification unit 16 to issue a notification. The notification mode is as it is, with no changes to the lighting unit 12, with the sound output unit 49 outputting a "beep beep" buzzer sound at a volume higher than normal, and with no changes to the display unit 48. A notification is sent to the mobile terminal 30 that the fan 11 is operating at a low airflow rate.

[0070] The situation at this time is assumed to be as follows: No cooking is being done, but a hot pot is placed on the cooking appliance 20. There is no one in the kitchen, but it is somewhat noisy (for example, the coffee grinder is running). At this time, odors from inside the house are bothersome, so an operation control command for low airflow is given from the living room or elsewhere using the mobile terminal 30. In this case, since the kitchen space is bright, it is judged that a sound notification is the most appropriate, and the volume of the notification is increased. Also, from information from the acceleration sensor of the mobile terminal 30, it is judged that the cook is moving around the house, and since there is a possibility that the cook will not be noticed by sound, the mobile terminal 30 is notified that the range hood 10 is operating as instructed.

[0071] 9th concrete example ((3) in the table of Figure 8). Blower 11 operates at high airflow. The surrounding information is as follows: a command to start heating has been detected from the cooking device operation unit 23; the temperature detected by the temperature sensor 50 is 180°C; the human presence sensor 53 has detected a person and detected their presence; the sound detection value of the sound collector 54 is about 55db, which is somewhat noisy; and the detection value of the illuminance sensor 52 is about 5000K, which is daylight white.

[0072] From this information, the control unit 14 determines that the cooking device 20 is in a heating state, the temperature of the food being cooked is 180° C., the surroundings are bright and somewhat noisy, and the cook is performing high-temperature cooking. The information from the mobile terminal 30 is an operation control command for low airflow and information on an access point. The control unit 14 determines that the access point information indicates an outside access point (the location where the operation was performed is outside the home). The control unit 14 selects the notification mode that is most suitable for the determined situation from among a plurality of notification modes stored therein, and controls the notification unit 16 to issue a notification. The notification is made by making the lighting unit 12 flash red, by making the sound output unit 49 emit a beep sound at a volume higher than normal, and by displaying text asking whether to accept the reduction in airflow on the display unit 48. A notification is sent to the mobile terminal 30 that cooking is in progress. Here, the flashing red light of the lighting unit 12, the change in the buzzer sound of the sound output unit 49, and the increase in the volume are examples of a predetermined notification in a highly recognizable manner. The present invention is not limited to this, and any notification that is more likely to attract the user's attention than usual may be used. Since the control to reduce the air volume unintentionally by the cook during cooking may be a safety problem, the notification is made in such a manner that is more likely to attract the user's attention.

[0073] This allows the cook to know that there is a control command to reduce the air volume of blower 11, and allows the cook to take measures such as canceling the control command as necessary. Furthermore, the person who operates the mobile terminal 30 can know that cooking is in progress and can perform operations such as canceling the control command to reduce the airflow.

[0074] Specific example 10 ((4) in the table of Figure 8). Blower 11 operates at high airflow. The surrounding information is as follows: a command to start heating has been detected from the cooking device operation unit 23; the temperature detected by the temperature sensor 50 is 180°C; the human presence sensor 53 has not detected any people and no one is present; the sound detection value of the sound collector 54 is around 60db and is somewhat noisy; and the detection value of the illuminance sensor 52 is around 5000K and is daylight white.

[0075] From this information, the control unit 14 determines that the cooking appliance 20 is in a heating state, the temperature of the food being cooked is 180° C., the surroundings are bright and somewhat noisy, and the cook is not near the range hood. The information in the mobile terminal 30 includes an operation control command for low airflow and access point information. The control unit 14 determines that the access point information indicates an outside access point (the location where the operation was performed is outside the home). The control unit 14 selects the notification mode that is most suitable for the determined situation from among a plurality of stored notification modes, displays text on the display unit 48 asking whether or not to accept a reduction in airflow, and notifies the mobile terminal 30 that cooking is in progress. When the motion sensor 53 transmits a signal indicating the presence of a person, the notification unit 16 is controlled to cause the lighting unit 12 to flash red, and the sound output unit 49 outputs a beeping buzzer sound at a volume higher than normal. Here, the ninth and tenth concrete examples both perform highly identifiable notifications by flashing the lighting unit 12 in red and changing and increasing the volume of the buzzer sound of the sound output unit 49, but in the tenth concrete example, a predetermined notification is made after the presence of the human sensor is detected. Even if someone goes to get ingredients during cooking, the notification is made after confirming that someone is present, so information can be conveyed more reliably to the person to be notified.

[0076] Specific example 11 ((5) in the table of Figure 8). Blower 11 operates at low airflow. The surrounding information is as follows: a command to start heating has been detected from the cooking device operation unit 23; the temperature detected by the temperature sensor 50 is 80°C; the human presence sensor 53 has not detected any people and no one is present; the sound detection value of the sound collector 54 is around 60db and is somewhat noisy; and the detection value of the illuminance sensor 52 is around 5000K and is daylight white.

[0077] From this information, the control unit 14 determines that the cooking appliance 20 is in a heating state, the temperature of the food being cooked is 80° C., the surroundings are bright and somewhat noisy, and the cook is not near the range hood 10. The information of the mobile terminal 30 includes a command to set a timer for 15 minutes and access point information. The control unit 14 determines that the access point information indicates an outside access point (the location where the operation was performed is outside the home). The control unit 14 changes the color temperature (which may be a color such as an RGB value) of the lighting unit 12 according to the remaining time on the timer, and when the set time has elapsed, the sound output unit 49 plays a melody to notify the user that the set time has elapsed. The display unit 48 displays the elapsed time in numbers. When the set time has elapsed, the mobile terminal 30 is notified that the time has elapsed. The situation at this time is as follows: You are using the cooking appliance 20 for non-high temperature cooking, for example stewing, and you set the timer for 15 minutes until the stewing is finished, and then you leave the kitchen, leaving the kitchen lights on. In this situation, the color temperature (which may be the color of RGB values) will change according to the time that has elapsed on the timer. This allows the user to know the remaining time on the timer from the change in brightness (change in color) in the kitchen.

[0078] The range hood 10 of the present invention can be as follows. When a plurality of people operate the range hood 10 using the mobile terminals 30, the users are registered on the application side, and the blinking response of the lighting unit 12 is made different for each mobile terminal 30. For example, a command from the father's mobile terminal 30 is set to blink twice, and a command from the mother's mobile terminal 30 is set to blink three times. In this manner, it is possible to determine who has remotely operated the range hood 10. Instead of blinking the illumination unit 12, the color of the illumination unit 12 may be changed for each mobile terminal 30 that has received a command. In addition, a notification may also be sent to the paired mobile terminal 30 along with the notification from the range hood 10.

[0079] A CO2 sensor may be installed in a living room or other room, and information from the CO2 sensor may be received by a mobile terminal 30 held by a person in the living room, and if the CO2 concentration exceeds a certain specified value, the mobile terminal 30 may instruct the range hood 10 to operate ventilation, and the range hood 10 may inform the person in the living room that it is about to start automatic ventilation operation by blinking the lighting unit 12. In this way, a user who confirms the increase in CO2 concentration on the mobile terminal 30 can notice that the range hood 10 has operated to eliminate the CO2 concentration. Using the GPS function of the mobile terminal 30, the lighting unit 12 is set to blink when a family member returns near the house. This allows the person at home to know that a family member has returned near the house, and allows them to prepare dinner as soon as they arrive. If there are multiple family members, each family member can be identified by having the lighting unit blink a different color. [Explanation of symbols]
