Description

  The present invention relates to a ventilator, and more particularly to a ventilator used with, for example, a cooking appliance.

  In recent years, cooking appliances have been used as cooking stoves such as boiled and fried foods, cooking stoves used for cooking foods such as meat and fish, and cooking stoves such as gas grills. A gas cooker is used in which ventilation is performed by interlocking with a ventilation device (range hood) provided in a room (generally a kitchen).

  Patent Document 1 proposes a ventilation device (range hood) that performs a ventilation operation in conjunction with the use of a gas stove or other device that requires such ventilation.

  In the case of this ventilator, when equipment that requires ventilation is used, it is configured to operate automatically by the infrared signal for starting ventilation operation sent from the equipment, so ventilation is required. Combustion gas and the like generated by the use of the device can be reliably discharged outside from a room (generally a kitchen) in which the device is installed.

  By the way, in paragraph 0162 of Patent Document 1, it is described that radio communication using radio waves may be performed as communication between the stove side and the ventilator side. When wireless communication using radio waves is performed as communication between two or more dwelling units such as apartment houses, and similar stoves and ventilation devices are installed in each dwelling unit, radio waves are used. When performing wireless communication between a stove and a ventilator installed in the same room when performing wireless communication, there is no problem, but the stove and the room where the stove is installed are different. If wireless communication is performed with a ventilator installed in a room, when using a stove, the ventilator installed in the room where the stove is installed (ventilator that should perform ventilation operation) Not installed in a room separate from the stove Ventilation equipment is a problem that'll be gone a ventilation operation occurs.

  In addition, when a weak radio wave having a communicable distance of about 3 m is used as a communication medium, particularly in the case of an apartment house, for example, a gas stove installed in one of the two adjacent units, There is a possibility that the ventilator installed in the other dwelling unit may perform wireless communication. In such a case, it is fully conceivable that the above-described inconvenience occurs.

  The present invention solves the above-mentioned problem, and properly performs a malfunction in which the above-described interlocked ventilation operation control is executed by a radio wave transmitted from a device other than the specific device paired with the ventilation device. An object of the present invention is to provide a highly reliable ventilation device that can be prevented.

In order to achieve the above object, the ventilator of the present invention comprises:
A signal receiving unit that receives data for communication by radio waves transmitted from a device that requires ventilation, and a control unit that controls ventilation operation,
When the signal reception unit receives a radio wave including ventilation operation start data transmitted from the device, the control unit starts ventilation operation, and the signal reception unit includes ventilation operation stop data transmitted from the device. A ventilator configured to perform linked ventilation operation control, wherein the control unit stops ventilation operation when receiving radio waves,
The ventilation operation start data and the ventilation operation stop data include a device ID code set in the device,
When the device ID code included in the communication data received by the signal receiving unit matches a specific ID code that is a device ID code set for a specific device, the control unit performs the linked ventilation operation. Execute control,
When the device ID code included in the communication data received by the signal receiving unit does not match the specific ID code, the control unit does not execute the linked ventilation operation control,
The signal receiving unit receives the device ID code set in the specific device from the specific device by wired communication,
The device ID code received from the specific device by the wired communication is set as the specific ID code.

  In the ventilator of the present invention, it is preferable that the communication data includes data relating to the magnitude of the ventilation air volume in the ventilation operation.

  The ventilator of the present invention is configured as described above, and includes the device ID code set in the device in the ventilation operation start data and the ventilation operation stop data, and for the communication received by the signal receiving unit. When the device ID code included in the data matches the specific ID code set for the specific device, the interlocked ventilation operation control is executed, and when the ID code does not match, the interlocked ventilation operation control is not executed. Thus, the device ID code set for the specific device is received from the specific device, and the device ID code received from the specific device is set as the specific ID code by wired communication. The malfunction which performs interlocking ventilation operation control by the electromagnetic wave transmitted from apparatuses other than the specific apparatus paired with the ventilation apparatus can be prevented appropriately.

  That is, since the device ID code received by wired communication is set as the specific ID code, it is possible to prevent malfunction due to radio waves transmitted from devices other than the paired specific device, and reliability. High ventilation device can be provided.

  Further, in the ventilator of the present invention, when the communication data includes data relating to the magnitude of the ventilation air volume in the ventilation operation, the ventilation air volume can be changed according to the use state of the device, so that it is unnecessary. It becomes possible to prevent improper interlocking ventilation operation due to a large air volume or a small air volume. Such an aspect is particularly significant when the device is a gas cooker that often involves fluctuations in the combustion state.

The ventilation operation is started by energizing and driving the exhaust fan 101.

  When the signal receiving unit 200S receives a radio signal from the signal sending unit 100S of the gas stove 100 using the radio wave for stopping the ventilation operation during the ventilation operation in which the exhaust fan 101 is driven, the control unit (FIG. (Not shown) is configured to stop energization of the motor 107 that drives the exhaust fan 101, stop driving the exhaust fan 101, and stop the ventilation operation.

<Characteristic configuration>
Next, the characteristic structure of the ventilation apparatus concerning embodiment of this invention is demonstrated.

  In the range hood 110, as described above, the signal receiving unit 200S (receives communication data by radio waves transmitted from the signal sending unit 100S (FIG. 1) provided in the gas stove 100 which is a device requiring ventilation. 2) and a control unit (not shown) for controlling the ventilation operation.

  In the range hood 110, when the signal receiving unit 200S receives the radio wave including the ventilation operation start data transmitted from the signal sending unit 100S of the gas stove 100, the control unit included in the range hood 110 starts the ventilation operation. When the receiving unit 200S receives the radio wave including the ventilation operation stop data transmitted from the signal sending unit 100S of the gas stove 110, the control unit provided in the range hood 110 is configured such that the control unit provided in the range hood 110 stops the ventilation operation. However, it is comprised so that the interlocking ventilation operation control with the gas stove 100 may be performed.

  The ventilation operation start data and the ventilation operation stop data include a gas stove ID code (device ID code) set in the gas stove 100.

  When the ID code for the gas stove included in the received communication data matches the specific ID code set in the specific gas stove (gas stove paired with the range hood) 100, the control unit included in the range hood 110 is linked. Ventilation operation control is executed.

  On the other hand, when the gas stove ID code included in the received communication data does not match the specific ID code, the control unit provided in the range hood 110 does not execute the interlocked ventilation operation control.

  That is, the linked ventilation operation control is executed only when the gas stove ID code included in the received communication data matches the specific ID code set in the specific gas stove (gas stove paired with the range hood) 100, When they do not match, the linked ventilation operation control is not executed.

  Further, the range hood 110 is configured to be able to receive the gas stove ID code from the gas stove 100 by wire communication, and the gas stove ID code received by wire communication is set as the specific ID code. It is configured.

  Specifically, the range hood 110 is provided with a ventilator side-wired communication connection unit 250 (FIG. 2), and the gas stove 100 is provided with a stove side-wired communication connection unit 150 (FIG. 1). The ventilator side-wired communication connection unit 250 and the stove side-wired communication connection unit 150 are configured to be connected by a wired communication line (not shown).

After acquiring the ID code, a communication line for wired communication (not shown) connecting the stove side-wired communication connection unit 150 (FIG. 1) of the gas stove 100 and the ventilator side-wired communication connection unit 250 of the range hood 110 to each other. Is removed. Therefore, when the gas stove 100 and the range hood 110 are used, the communication line for wired communication does not get in the way.

  Further, as an operation for starting wired communication performed on the gas stove 100 side, for example, an operation of a dedicated communication start switch (not shown) provided on the grill setting operation unit 6 or an operation on the grill setting operation unit 6 is provided. Various forms such as simultaneous pressing of a plurality of setting switches (not shown) for the grill can be adopted, and the form is not particularly limited.

  Also, as the wired communication system as described above, various well-known communication systems can be adopted, and further detailed description thereof is omitted.

  The ventilator (range hood) 110 of this embodiment is configured as described above, and the gas stove ID code received by wired communication is set as the specific ID code. It is possible to appropriately prevent a malfunction in which the linked ventilation operation control is executed by a radio wave transmitted from a gas stove other than the specific gas stove 100 paired with the range hood 110.

  Moreover, in this embodiment, it is comprised so that the data regarding the magnitude of the ventilation air volume in the ventilation operation | movement of the range hood 100 may be included in the communication data included in the radio wave transmitted from the gas stove 100 and received by the range hood 110.

  As a result, since the ventilation air volume of the range hood 110 can be automatically adjusted according to the use condition of the gas stove 100, ventilation by the unnecessary large air volume in the range hood 110 and the interlocked ventilation operation by the excessively small air volume are performed. It becomes possible to prevent.

  Incidentally, such an aspect is particularly meaningful when the device requiring ventilation is a gas cooker such as the gas stove 100, which often involves fluctuations in the combustion state, as in this embodiment. is there.

  However, the configuration in which data related to the magnitude of the ventilation air volume in the ventilation operation of the range hood 110 is included in the communication data included in the radio wave transmitted from the gas stove 100 and received by the range hood 110 is an arbitrary configuration. The communication data transmitted from the gas stove 100 and included in the radio wave received by the range hood 110 may be configured not to include data related to the magnitude of the ventilation air volume in the ventilation operation of the range hood 110.

[Another embodiment]

  (1) Although the said embodiment demonstrated the case where the ventilation apparatus 110 was a range hood provided with the hood part 103, you may comprise so that the ventilation fan which does not provide the hood part 103 may be used as a ventilation apparatus.

In the case of an electric stove, the purpose of operating the ventilator is not to eliminate indoor pollution due to combustion exhaust gas, but to prevent contamination from cooked products such as smoke from oil.

  (3) When performing ventilation-linked operation, the ventilator transmits, via radio waves, feedback data regarding the operating state including data regarding ON / OFF of the blower (exhaust fan) and data regarding the ventilation air flow per unit time. The gas stove as a specific device that requires ventilation can be configured to receive radio waves including feedback data related to the above operating conditions. When data is not received (feedback data on the magnitude of the ventilation airflow) that ventilation is being executed with the “required ventilation airflow” sent by the gas stove when a predetermined time has elapsed after sending the ventilation operation start data including Stop the operation of the gas stove or issue an alarm from the gas stove It may be configured to. When configured in this way, it is possible to avoid continuing the combustion of the gas stove in a state where the desired ventilation is not performed, or to encourage the user to check the combustion state of the gas stove. Can be improved.

  In other respects, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention.
