Description

  The present invention relates to a cooking device having a range hood having a movable hood, and a cooking device that operates in conjunction with the movement of the hood, and a configuration of the hood that moves in cooperation with the heating operation of the cooking device.

  Conventionally, there are many fixed range hoods, and it is difficult to use the upper space, so a storage shelf is provided at the top of the range hood, and the storage shelf is moved downward to approach the user. Thus, a configuration that facilitates storage work has been proposed. (For example, refer to Patent Document 1).

  However, a range hood equipped with a hood and a ventilation fan is installed above the heating cooker as a ventilator for sucking and discharging oil smoke, water vapor, combustion gas, etc. generated and discharged during cooking. In the configuration described in Patent Document 1, it is necessary to secure a moving space of the storage shelf, and the holding mechanism for the storage shelf is complicated, so recently, the range hood is moved up and down by an elevator. There is known a cooking system provided with a liftable hood and a filter housed in the lift hood (see, for example, Patent Document 2).

  The range hood drives the ventilation fan to suck the gas generated and exhausted during cooking from the lifting hood, and discharges the sucked air from the exhaust duct to the outside through the filter inside the lifting hood. In addition, the oil and water vapor in the air sucked at this time are collected by a filter.

  Normally, the range hood is installed at a high place. The reason is that if it is installed at a very low position, the range hood is located directly above the heating cooker and hinders cooking, and there is also a need to avoid the danger caused by the influence of fire, heat and the like.

  On the other hand, oil or the like adheres to the filter, and when the oil is used for a long time, the adhered oil drops from the filter and soils the cooking device or falls into a cooking pan. In order to prevent this, it is necessary to periodically clean or replace the filter. In this case, the user lowers the elevating hood and lowers it from the upper surface of the cooking device to a height position of about 200 mm, for example, so that the user does not go up on the table or forcibly reach out. The filter can be easily cleaned and replaced.

Similarly, the second cooking device side communication means 70a is composed of a light emitting element that emits infrared light, and the second elevating hood side communication means 70b is composed of a light receiving element that is turned on when receiving infrared light. The

  In the present embodiment, the first communication means 68a, 68b or the second communication means 70a, 70b are configured using unidirectional communication means using an infrared sensor, but the communication means is configured by wire. Alternatively, other wireless communication means such as Bluetooth or bidirectional communication means may be used.

  On the other hand, the elevator 46 includes elevator control means 72 for controlling the electric motor 34 as the lifting means, and the elevator control means 72 is realized using a microcomputer. The elevator 46 is provided with at least two limit switches as position detecting means for detecting the position of the elevator hood 20, and in this embodiment, two limit switches, an upper limit switch 74a and a lower limit switch 74b, are provided. Is provided. The upper limit switch 74a and the lower limit switch 74b are configured such that the upper limit switch 74a is turned on when the lifting hood 20 is at the upper limit of the movable range, and the lower limit switch 74b is turned on when the lifting hood 20 is at the lower limit of the movable range. When the upper limit switch 74a and the lower limit switch 74b are both OFF, the lift hood 20 is set to be detected at the intermediate position. The ON / OFF signals of the limit switches 74a and 74b are input to the elevator control means 72, and further input to the heating control means 66 via the first communication means 68a and 68b. Based on these signals, the lift hood 20 The position is displayed on the display means 58. In the present embodiment, when the lifting hood 20 is at the upper limit, the distance between the lifting hood 20 and the heating cooker 2 is a predetermined distance, and the predetermined distance is set to 80 cm, for example.

  In the present embodiment, the position detecting means for detecting the position of the lifting hood 20 is configured by the limit switches 74a and 74b, but may be configured by a reed switch. It is also possible to configure the light emitting element and the light receiving element. In this case, the position of the lifting hood 20 is determined by detecting whether the light emitted from the light emitting element toward the light receiving element is received by the light receiving element. Can be detected. Furthermore, a storage unit for storing the number of rotation pulses of the electric motor 34 is provided in the elevator control means to be described later, the number of rotation pulses of the electric motor 34 is measured, and the lifting hood 20 is moved to the upper limit position or with a predetermined number of rotation pulses. It is also possible to stop each at the lower limit position. In addition, when the position detection means is configured by a distance sensor using an infrared sensor or an ultrasonic sensor, not only the upper and lower limits of the lift hood 20 but also the position in the height direction can be detected.

  The elevator control means 72 sends a signal indicating any one of “upper limit position”, “intermediate position”, and “lower limit position”, which is a detection result of the limit switches 74a and 74b, from the first elevator-side communication means 68b to the first heating. It is transmitted to the cooking device side communication means 68a every first predetermined time (for example, 0.1 second).

  The heating control means 66 receives the detection results of the limit switches 74a and 74b via the first communication means 68a, and turns off the heating means 62 when it is shorter than a predetermined distance (when the detection result is other than the “upper limit position”). . Thereby, when the distance of the heating cooker 2 and the raising / lowering hood 20 is near, since the output of the heating means 62 can be turned off, a safe cooking system can be provided.

  The heating control means 66 receives the detection results of the limit switches 74a and 74b via the first communication means 68a and 68b, but if the data reception is interrupted for a second predetermined time (for example, 0.3 seconds), the heating means The safety of the heating cooker 2 is improved by performing the following control according to the operation state of 62.

  That is, when the heating means 62 is in a heating operation, the heating means 62 is stopped, and the heating means 62 is prohibited from starting heating, while when the heating means 62 is in a heating stop, the heating means 62 is prohibited from starting heating. Is set.

  In the present embodiment, any one of the “upper limit position”, “intermediate position”, and “lower limit position” of the lifting hood 20 is detected by the limit switches 74a and 74b. The data representing the relative distance between the heating cooker 2 and the lift hood 20 is transmitted from the first elevator-side communication means 68b to the first heating cooker-side communication means 68a, and the limit switch or the reed switch 3 is set. When two or more are provided, the corresponding position data is transmitted from the first elevator side communication means 68b to the first cooking device side communication means 68a.

  In the present embodiment, the first predetermined time is set to 0.1 seconds, for example, and the second predetermined time is set to 0.3 seconds, for example. However, the distance between the elevating hood 20 and the heating cooker 2 is less than the predetermined distance. It is not limited to this as long as the output of the heating means 62 can be stopped before it becomes shorter.

  The elevator control means 72 communicates with the lift hood control means 78 provided in the lift hood 20 by a TTL signal via a wire, and the lift hood control means 78 is realized using a microcomputer. The communication between the elevator controller 72 and the elevator hood controller 78 is not limited to wired communication, and may be realized by bidirectional wireless communication means such as Bluetooth or an infrared sensor.

  The lift hood control means 78 controls the drive of the ventilation fan 18. The lift hood control means 78 obtains operation information from the heating cooker 2 via the second communication means 70a, 70b. This operation information includes a command to turn on / off the ventilation fan 18 and a command to increase / decrease the rotational speed of the ventilation fan 18. The operation information includes a command to raise and lower the lifting hood 20, which is sent to the elevator control means 72 via the lifting hood control means 78.

  In the present embodiment, the second cooking device side communication means 70a is configured to transmit a command when each switch for operating the ventilation fan 18 or the elevator 46 is pressed.

  Since the storage space (elevating rack 30) is disposed above the elevating hood 20 and the elevating hood 20 is lowered, the storage space is lowered in conjunction with each other, so that the user can easily use the storage space.

  In the present embodiment, the moving direction of the elevating hood 20 is the vertical direction. However, if the storage space (elevating rack 30) on the elevating hood 20 can be used when the elevating hood 20 is lowered, it is not limited to the vertical direction. For example, an object that moves between an upper limit position and a lower limit position while drawing an arcuate locus is also included. Further, in the configuration in which the elevating hood 20 is moved up and down in the vertical direction, the elevating hood 20 can be moved back and forth at the lower limit position, and the position where the elevating hood 20 is pulled forward manually or electrically, that is, the front end position is set to the ventilation fan 18. The position where the lift hood 20 is retracted manually or electrically, that is, the rear end position (the position where the lift hood 20 is stored) can be set as the non-operating position of the ventilation fan 18 by setting the operating position. Therefore, in this specification, the raising / lowering hood 20 may be called a mobile hood.

  As will be described later (for example, the fourth embodiment shown in FIG. 10), the lifting hood operating means that can perform the lifting operation of the lifting hood 20 and the lifting state of the lifting hood 20 are also provided on the lifting hood 20 side. When the lift hood display means is provided, a signal from the lift hood operation means is input to the lift hood control means 78, and a signal output from the lift hood control means 78 is input to the lift control means 72 to The electric motor 34 is driven and controlled by the control means 72. When the lift hood 20 is moved up and down by driving the electric motor 34, signals from the limit switches 74a and 74b are input to the lift hood control means 78 via the lift control means 72, and the position of the lift hood 20 is indicated as the lift hood display means. Is displayed.

  Further, a switch for turning on / off the ventilation fan 18 may be provided on the lifting hood 20 side.

  Further, in the present embodiment, limit switches 74a and 74b as position detecting means for detecting the position of the lifting hood 20 are provided on the range hood 10 side. However, the position detecting means is configured by an infrared sensor or an ultrasonic sensor. If provided on the cooking device 2 side, the heating control means 66 can similarly regulate the operation of the cooking device 2 based on the detection result.

  Further, in the present embodiment, the control for restricting the operation of the heating unit 62 is performed based on the control information input from the range hood 10 via the first communication unit 68a. The control of the operation of the elevator 46 may be performed by outputting to the elevator controller 72 via the communication means 70a. For example, when the elevator controller 72 recognizes that the cooking device 2 is operating based on the control information input via the second range hood side communication unit 70 b and the elevator hood controller 78, From the detection results of the upper limit switch 74a and the lower limit switch 74b as detection means, when it is detected that the elevating hood 74a is in the “intermediate position”, even if it is allowed to enter the ascending mode, the descending mode is entered. The elevator 46 may be controlled so as not to enter. Thereby, a freedom degree can be given to operation | movement of the raising / lowering hood 20. FIG.

The control method of the heating cooker 2 and the elevating hood 20 will be further described.
When the elevating hood 20 is below the upper limit position, the heating control means 66 instructs the display means 58 to display “heating prohibited”, and turns on / off the heating means 62. The operation of is not accepted. When the on / off key 56 is pressed when heating is prohibited, the notification means 76 repeats, for example, 0.3 second ON and 0.3 second OFF five times to notify that heating is prohibited. If it can be recognized, it is not limited to this.

  Further, when the cooking device 2 is in operation, the heating control means 66 instructs the display means 58 to display “prohibition of movement of the lifting hood” and the fan DOWN key for lowering the lifting hood 20. 50b may not be accepted, and the display unit 58 may display that the movement of the elevating hood 20 is restricted in addition to the display of “heating prohibited” of the heating unit 62.

  When the communication of the first communication means 68a, 68b is interrupted for a second predetermined time or more, if the heating means 62 is in a heating operation, the heating means 62 is stopped, and “U01” is displayed on the display means 58 to communicate. Is displayed informing that the heating means 62 has been stopped due to interruption. When the heating unit 62 is stopped, the notification unit 76 repeats, for example, 0.5 second ON and 0.5 second OFF twice to notify that the heating unit 62 has been stopped. Furthermore, the notification means 76 can also be set to notify the movement restriction of the elevating hood 20.

  In this embodiment, “U01” is displayed to indicate that communication has been interrupted, but an LED may be lit to indicate that the heating means 62 has been stopped because communication has been interrupted, If it can recognize that the heating means 62 was stopped because communication was interrupted, it is not restricted to this. In addition, to notify that the heating means 62 has been stopped, ON for 0.5 seconds and OFF for 0.5 seconds were repeated twice. is not.

  As described above, the heating cooker 2 according to the present embodiment is a lifting hood as a mobile hood that sucks smoke and heat generated by a heated object (the cooking container 60 and the cooking object inside the cooking container 60) and discharges it to the outside. 20, a heating system provided in a cooking system including a range hood 10 having an elevator 46 as a moving means for moving the lifting hood 20 and a lifting hood control means 78 as a movement control means for controlling the operation of the moving means 46. First communication for transmitting control information between the heating means 62 for heating the cooking container 60, the heating control means 66 for controlling the operation of the heating means 62, and the range hood in the cooking device 2. Means 68a and second communication means 70a, and the heating control means 66 is provided in the heating cooker 2 with the control information input from the range hood 10 via the first communication means 68a. At least one of a detection result of a position detection unit that detects the position of the lift hood 20 and a detection result of a movement detection unit (see Embodiment 2) that is provided in the heating cooker 2 and detects the movement of the lift hood 20. Based on one, when the elevating hood 20 recognizes that it is in a predetermined position where the heating operation of the heating means 62 should be restricted, or it is recognized that it is in a predetermined movement mode where the heating operation of the heating means 62 should be restricted. When this is done, control information is output to the elevator control means 72 via the second communication means 70a to control the operation of the elevator 46, and control input from the range hood 10 via the first communication means 68a Since at least one of the controls for regulating the operation of the heating means 62 based on the information is performed, the cooking system is installed in combination with the range hood. For example, the lifting hood 20 is moved to clean the lifting hood 20, replace the filter, store the lifting hood 20, or use the space above the lifting hood 20 effectively. The effects obtained by being movable can be used as appropriate. In addition, when the elevating hood 20 is moved or when the heating cooker 2 is operated, when the elevating hood 20 is in an inconvenient position, the range hood 10 corresponds to the operating state of the heating means 62 of the heating cooker 2. Since the heating cooker 2 can regulate the heating operation of the heating means 62 by restricting the position and moving operation of the lifting hood 20, the position of the lifting hood 20 and the heating cooker 2 may be unsatisfactory. Safe situations and other undesirable situations can be prevented.

  Here, the “inconvenient position” of the elevating hood 20 means “intermediate position” when the “upper limit position”, “intermediate position”, and “lower limit position” of the elevating hood 20 are detected by the limit switches 74a and 74b. In the case of a configuration in which the vertical position of the lifting hood 20 is detected by the limit switches 74a and 74b, the lower limit position is a predetermined position where the heating operation of the heating means 62 should be regulated. In the mutual positional relationship between the heating cooker 2 and the elevating hood 20, when the elevating hood 20 is within a range set to 0 to 80 cm from the heating cooker 2 as an unsafe position, or any of the cooking systems has its function Is in a range set as a position that cannot be fully satisfied.

  Whether the heating control means 66 outputs control information for regulating the operation of the elevator 46 via the second heating cooker-side communication means 70a in order to suppress the thermal influence of the cooking container 60 on the lifting hood 20. Or the operation of the heating means 62 is regulated based on the control information input from the range hood 10 via the second heating cooker side communication means 68a, or at least one of them is performed. It can be prevented from being deformed or burned by the heat generated by the container 60, and is safe. In addition, in order to suppress the thermal influence which the cooking container 60 gives to the raising / lowering hood 20, as a result, the raising / lowering hood 20 leaves | separates more than the predetermined distance (80 cm in this Embodiment) with less thermal influence than the heating cooker 2. Or the heating operation of the heating cooker 2 is stopped or reduced.

  The heating control means 66 also provides control information for restricting the operation of the elevator 46 so that the distance between the elevating hood 20 and the heating means 62 is equal to or greater than a predetermined value when the heating means 62 is performing a heating operation. When the heating means 62 is not in the heating operation, the operation of the elevator 46 is regulated while the second cooking hood side communication means 70a and the second range hood side communication means 70b output to the range hood 10. By not outputting the control information to the range hood 10 via the second heating cooker side communication means 70a and the second range hood side communication means 70b, the cooking container 60, the flame generated by the food to be cooked, etc. The thermal influence given to 20 can be suppressed, and overheating and combustion of the lift hood 20 can be prevented to ensure safety.

  Moreover, it is preferable to provide the heating control means 66 with a communication abnormality detecting means (not shown) for detecting whether or not communication with the range hood 10 is normally performed. In this case, when the communication abnormality detection unit detects a communication abnormality, the operation of the heating unit 62 is restricted, so that when the communication is interrupted for some reason or an abnormal situation occurs, the heating operation of the heating cooker 20 is performed. Alternatively, the moving hood control means 78 and the heating control means 66 cannot recognize the moving state such as the position of the elevating hood 20 and the heating cooker 2 or the like in a situation where the mutual positional relationship between the elevating hood 20 and the heating cooker 2 is not preferable. It is possible to prevent the elevator 46 of the range hood 10 from performing an undesirable operation.

  Further, the heating control means 66 determines the distance between the elevating hood 20 and the heating means 62 based on the control information regarding the movement or position of the elevating hood 20 input via the first heating cooker side communication means 68a. When it is determined that it is shorter than a predetermined distance (distance where it can be determined that the influence of the heat or flame of the cooking container 60 or the cooking object can be suppressed, for example, 80 cm), the operation of the heating means 62 is restricted. The thermal effect on 20 can be suppressed.

  Further, by providing the range hood 10 with movement detection means for detecting the movement of the lifting hood 20 or position detection means limit switches 74a and 74b for detecting the position of the lifting hood 20, the heating control means 66 detects these movements. The position of the elevating hood 20 is changed to a predetermined position (for example, in the present embodiment, the elevating hood 20 of the elevating hood 20 via the first heating cooker side communicating means 68a and the first range hood side communicating means 68b from the means or the position detecting means. Control information indicating that the vehicle has moved away from the “upper limit position” or control information indicating that a predetermined position (for example, “intermediate position” or “lower limit position” of the lift hood 20 in the present embodiment) has been reached. When input, the distance between the elevating hood 20 and the heating means 62 is a predetermined distance (the influence of the heat and flame of the cooking container 60 or the cooking object can be suppressed). Sectional possible distance, for example because it is determined shorter than 80 cm) to regulate the operation of the heating means 62, it becomes easy to confirm the position of the vertical hood 20 should regulate the operation of the heating means 62.

  The heating control means 66 sends control information indicating that the elevating hood 20 has entered the movement mode or the lowering mode from the elevator control means 72 to the first range hood side communication means 68b and the first heating cooker side communication means. Since the operation of the heating means 62 is restricted when input is made via 68a, it is easy to confirm the position of the elevating hood 20 where the operation of the heating means 62 should be restricted.

  When the operation of the heating means 62 is in a position where the operation of the heating means 62 should be restricted, such as when the elevating hood 20 is not in a predetermined position, the operation of the heating means 62 is restricted, or the heating cooker 2 is in operation. Since the display means 58 or the notification means 76 for displaying or notifying that the movement of the elevating hood 20 is restricted is provided, the user is restricted from operating the heating means 62 or moving the elevating hood 20. You can know why you are, and you won't be unnecessarily stupid.

  Furthermore, the range hood 10 in the present embodiment controls the elevating hood 20 that sucks and discharges smoke and heat generated by the cooking container or the cooking object, the elevating machine 46 that moves the elevating hood 20, and the elevating machine 46. The elevating hood control means 78 and the first range hood side communication means 68b and the second range hood side communication means 70b for transmitting control information between the cooking device 2 and the elevating hood control means. Reference numeral 78 denotes a detection result of the upper limit switch 74a and the lower limit switch 74b as range hood side position detection means for detecting the position of the lift hood 20, and detection of the range hood side movement detection means 80 for detecting the movement of the lift hood 20. Based on one of the results, the elevating hood 20 is in a predetermined position where the heating operation of the heating means 62 should be restricted. Or when it is recognized as a predetermined movement mode in which the heating operation of the heating means 62 should be restricted, control information corresponding thereto is sent to the first heating via the first range hood side communication means 68b. Control that outputs to the cooker side communication means 68a and controls the operation of the heating means 62, and input from the heating cooker 2 via the second cooker side communication means 70a and the second range hood side communication means 70b Since at least one of the controls for restricting the operation of the elevator 46 is performed based on the control information, the heating means 62 for heating the cooking container 60 and the heating control means 66 for controlling the operation are provided. By installing in combination with the cooker 2, for example, the elevating hood 20 is moved to clean the elevating hood 20, replace the filter, store the elevating hood 20, Including effective use of lifting the hood 20 headspace, depending on the installation mode, lift the hood 20 can be used as appropriate effects obtained by the mobile. In addition, when moving the elevating hood 20 or when operating the heating cooker 2, when the elevating hood 20 is in an inconvenient position, the elevating hood 20 depends on the operating state of the heating means 62 of the heating cooker 2. Since the heating cooker 2 can regulate the heating operation of the heating means 62 by restricting the position and moving operation of the lifting hood 20, the position of the lifting hood 20 and the heating cooker 2 may be unsatisfactory. Safe situations and other undesirable situations can be prevented.

  Moreover, the elevator control means 72 as a movement control means regulates the operation of the heating control means 66 via the first range hood side communication means 68b so as to suppress the thermal influence of the cooking container 60 on the lift hood 20. The control information is output, or the operation of the elevator 46 is restricted based on the control information input from the heating cooker 2 via the second range hood side communication means 70b, or at least one of them is configured. Thus, it is safe because the range hood 10 can be prevented from being deformed or burned by the heat or flame generated by the heating container 60 and the object to be cooked.

  Further, the elevator control means 72 serving as the movement control means receives control information for restricting the operation of the heating means 62 so that the operation of the heating means 62 is stopped or the heating output is reduced to a predetermined value or less. By outputting to the heating cooker 2 via the range hood side communication means 68b, the thermal influence which the cooking container 60 gives to the raising / lowering hood 20 can be suppressed, and overheating and combustion of the raising / lowering hood 20 are prevented and safety is ensured. can do.

  Further, the elevator control means 72 includes communication abnormality detection means (not shown) for detecting whether or not communication is normally performed with the first and second range hood side communication means 68b and 70b with the heating cooker 2. It is preferable to provide in. In this case, when the communication abnormality detection means detects a communication abnormality, the operation of the elevator 46 is restricted, so that when the communication is interrupted for some reason or falls into an abnormal situation, the heating operation of the heating cooker 20 or the elevating hood The moving hood control means 78 and the heating control means 66 cannot recognize the movement state of the position 20 and the like, and the heating cooker 2 or the range hood 10 is in a situation where the positional relationship between the lifting hood 20 and the heating cooker 2 is not preferable. It is possible to prevent the elevator 46 from operating undesirably.

  The elevator control means 72 as the movement control means includes control information indicating that the heating means 62 has been operated via the second heating cooker side communication means 70a and the second range hood side communication means 70b, and a power source. It can also be set to restrict the operation of the elevator 46 when any control information indicating that the switch is turned on is input.

  Further, based on the detection result of the movement detecting means for detecting the movement of the elevating hood 20 or the position detecting means for detecting the position of the elevating hood 20, when the elevating hood 20 is moving, or the elevating hood 20 and the heating means 62 If it is determined that the distance between the two is shorter than the predetermined distance, the operation of the elevator 46 is restricted during the operation of the heating unit 62 based on the control information input via the second elevator hood side communication unit 70b. Moreover, the thermal influence which the cooking container 60 gives to the raising / lowering hood 20 can be suppressed, the overheating and combustion of the raising / lowering hood 20 can be prevented, and safety can be ensured.

  Further, the elevator control means 72 as the movement control means makes it easy to control the elevator 46 by preventing the elevator hood 20 from entering the movement mode or at least the lowering mode when the operation of the elevator 46 is restricted.

Further, the elevator control means 72 as the movement control means receives a movement command for moving the lifting hood 20 from the heating cooker 2, and outputs a control signal corresponding to the movement command to the second cooking. When input through the device side communication means 70a and the second range hood side communication means 70b, the operation of the elevator 46 is controlled in accordance with the control signal, so the elevator hood 20 is inconvenient for the cooking device 2. It is possible to prevent the heating means 62 of the heating cooker 2 from operating in an unfavorable position.
Further, the elevator control means 72 as the movement control means sets the distance between the lift hood 20 and the heating means 62 to a predetermined value or more when at least the heating means 62 is in an operating state when regulating the operation of the elevator 46. The operation of the elevator 46 is regulated so that the heating container 60 or the object to be cooked can suppress the thermal effect on the elevator hood 20, and the overheating and combustion of the elevator hood 20 can be prevented to ensure safety. be able to.

  Further, the elevator control means 72 as the movement control means outputs control information for regulating the operation of the heating means 62 to the first range hood side communication means 68b, or regulates the operation of the elevator 46 at the same time. It is possible to prevent the heating means 62 of the heating cooker 2 from performing an undesired operation under the situation where the elevating hood 20 is in an unfavorable position with respect to the heating cooker 2.

  In this way, by configuring the cooking system, a user-friendly and safe cooking system can be provided.

  In the present embodiment, the range hood 10 has been described as having a control means for each of the lift hood 20 and the lift 46. However, as shown in FIG. 7, the upper limit switch 74a and the lower limit switch 74a are controlled by the lift hood control means 78. The detection result of the limit switch 74b is input, and any one of the “upper limit position”, “intermediate position”, and “lower limit position”, which are detection results of the upper limit switch 74a and the lower limit switch 74b, is communicated with the first heating cooker. It is good also as a structure which transmits to the heating control means 66 via the means 68a and the 1st range hood side 68b, controls the drive of the electric motor 34, and controls the raising / lowering of the raising / lowering hood 20. FIG.

  In the present embodiment, the first range hood side communication means 68b, which is the transmission means of the range hood 10, is configured to be installed in the elevator 46, but the communication performance is not affected by the elevation of the elevation hood 20. It is good also as a structure installed in the raising / lowering hood 20. As shown in FIG.

  The heating cooker 2 has been described as an electromagnetic induction heating cooker (induction heating cooker), but there may be a plurality of heating means 62 that are heating coils. In this case, when the heating operation of the heating cooker 2 is regulated according to the operation of the elevating hood 20, for example, it is safe if the operations of all the heating means 62 are regulated. Moreover, when restricting the raising / lowering operation | movement of the raising / lowering hood 20 according to operation | movement of the cooking-by-heating machine 2, for example, the heating condition of the at least any one heating means 62 of the cooking-by-heating machine 2 is performed. This is safe. Further, when the heating means 62 is a heating coil, that is, an electromagnetic induction heating cooker, when the heating operation is stopped, the temperature of the load rarely rises due to residual heat. It is easy to do.

Embodiment 2. FIG.
The control method of the heating cooker 2 and the range hood 10 in the cooking system according to the second embodiment of the present invention will be described with reference to FIG. Since the basic configuration of the present embodiment is the same as that of FIG. 7 of the first embodiment, different points will be mainly described. Further, the same functions as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 8 is a configuration diagram of the cooking system in the present embodiment. In FIG. 8, the movement detection means 80 which consists of Hall IC which can detect the operation state of the electric motor 34 as a drive source is provided. The movement detection means 80 detects the movement state of the lifting hood 20 from the operation state of the electric motor 34. In the present embodiment, if the electric motor 34 is rotating forward, the lifting hood 20 is “lowering”, and if the electric motor 34 is rotating backward, the lifting hood 20 is “raising”, and the electric motor 34 is stopped. “Stopped”.

  The elevating hood control means 78 sends the detection result of the movement detection means 80 to the heating control means 66 via the first communication means 68a, 68b. 1 is transmitted every predetermined time. The heating control means 66 receives the detection result of the movement detecting means 80 via the first communication means 68a and 68b, and turns off the heating means 62 when “down” or “up”.
