JP-A-7-231356

  A gas stove as a device in the home is a device that is used daily by residents, and it is conceivable to notify the external monitor of the use information of the gas stove. However, using the existing gas stove, the use information is externally monitored. It was something that could not be reported to.

That is, in order to notify the external monitor of gas stove use information, for example, when the stove ignition switch is operated, it is conceivable to notify the external monitor of the operation information as gas stove use information.
Then, in order to be able to notify the external monitor of the operation information of the ignition switch as the use information of the gas stove, the wireless communication unit for notification to the external monitor and the operation information of the ignition switch are acquired, and the ignition switch It is necessary to equip the gas stove with a communication control unit that communicates the operation information from the wireless communication unit as the gas stove usage information.

  Therefore, if a newly installed gas stove is equipped with a wireless communication unit or communication control unit, it is possible to notify the external monitor of the use information of the gas stove. Since the control unit is not equipped, the use information cannot be notified to an external monitor using an existing gas stove.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a gas stove that can notify an external monitor of gas stove use information while being an existing gas stove. .

The gas stove of the present invention is provided with a dry cell stored in a battery storage unit, a control unit that controls the operation of the combustion unit using the dry cell as a power source, and an igniter for ignition of the combustion unit,
The control unit is configured to operate the igniter using the dry battery as a power source, and the characteristic configuration is
A communication unit including a wireless communication unit for notification to an external monitor is stored in the battery storage unit in a state of being aligned with the dry battery,
A positive insertion terminal inserted between the positive electrode of the dry battery and the positive connection terminal of the battery housing; and a negative electrode of the dry battery and a negative connection terminal of the battery housing. A negative side insertion terminal inserted between the positive side insertion terminal, a voltage drop detection unit for detecting a voltage drop of the dry battery applied between the positive side insertion terminal and the negative side insertion terminal, and a voltage of the voltage drop detection unit And a communication control unit that communicates gas stove use information from the wireless communication unit based on the drop detection information.

That is, a communication unit including a wireless communication unit for notification to an external supervisor is stored in the battery storage unit in a state of being aligned with the dry battery.
Specifically, the communication unit inserts the plus side insertion terminal between the plus side electrode of the dry battery and the plus side connection terminal of the battery storage unit, and the minus side insertion terminal inserts the minus side electrode of the dry battery and the battery. The battery is housed in the battery housing part in such a form that it is inserted between the negative-side connecting terminal of the part.

  And, when the voltage drop detection unit that detects the voltage drop of the dry battery applied between the plus side insertion terminal and the minus side insertion terminal is operated to start combustion of the combustion unit, When a decrease in the voltage of the dry cell is detected, the communication control unit communicates the gas stove usage information from the wireless communication unit, and can notify the external monitor of the gas stove usage information.

In addition, the voltage of the dry battery as the power source for operating the control unit for controlling the operation of the combustion unit and the igniter for ignition of the combustion unit was activated even when the voltage was not consumed. Sometimes it will drop significantly.
Therefore, when the igniter is activated based on the operation of the ignition switch of the gas stove, the voltage drop detecting unit detects the voltage drop of the dry cell, and the communication control unit communicates the usage information of the gas stove from the wireless communication unit. Become.

Then, the communication unit including the wireless communication unit, the voltage drop detection unit, and the communication control unit can be stored in the battery storage unit in a state of being aligned with the dry battery using the surplus space of the battery storage unit in the existing gas stove. It can be formed in as small a size as possible.
In addition, the communication unit is inserted between the positive electrode of the dry battery and the positive connection terminal of the battery housing portion, and the negative insertion terminal is inserted between the negative electrode of the dry battery and the negative electrode of the battery housing portion. Storage in the battery storage portion in a form of being inserted between the side connection terminals can also be performed on the battery storage portion in the existing gas stove.

  Therefore, by installing a communication unit in the battery storage unit in the existing gas stove, the usage information of the existing gas stove can be notified to the external monitor.

  In short, according to the gas stove of the present invention, the use information of the gas stove can be notified to an external monitor even though it is an existing gas stove.

Further, in the gas stove according to the present invention, at least one of the plus side insertion terminal and the minus side insertion terminal is configured to be switchable from a conductive state to a non-conductive state,
When the wireless communication unit receives the stop command information transmitted from the external supervisor, the communication control unit moves at least one of the plus side insertion terminal and the minus side insertion terminal from the conductive state. The point is that it is configured to switch to the non-conductive state.

  That is, when the external supervisor feels abnormal, such as when the gas stove has not been used for several days or when he / she notices that the gas stove has been forgotten to turn off when going out, for example, the external supervisor holds it. By enabling the stop command information to be transmitted from the mobile terminal to the wireless communication unit of the communication unit, when the communication control unit receives the stop command information transmitted from the external supervisor, At least one of the terminal and the negative insertion terminal is switched from the conductive state to the non-conductive state so that the gas stove cannot be used.

  In other words, if at least one of the plus side insertion terminal and the minus side insertion terminal is switched from the conductive state to the non-conductive state, the power of the dry battery is not supplied to the control unit or the igniter that controls the operation of the combustion unit. Therefore, since the combustion part of the gas stove cannot be burned, the gas stove cannot be used.

  As described above, since the gas stove can not be used according to the stop command information from the external monitor, the gas stove can be switched to an unusable state by remote control as necessary. This is advantageous for improving the performance.

  In short, according to the further characteristic configuration of the gas stove of the present invention, safety can be improved.

The monitoring system of the present invention is provided with a relay wireless communication unit at a location where a gas stove having the above-described characteristic configuration is installed,
The wireless communication unit is configured to communicate with the relay wireless communication unit;
An external communication unit that communicates between the relay wireless communication unit and the portable terminal held by the external supervisor is provided.

  That is, the wireless communication unit of the communication unit communicates with the relay wireless communication unit provided in the place where the gas stove is installed (for example, kitchen), and the relay wireless communication unit and the external monitor The portable terminal to be held communicates via the external communication unit.

  As described above, since the wireless communication unit of the communication unit communicates with the relay wireless communication unit provided near the gas stove, the wireless communication unit of the communication unit has a simple configuration with a short communicable distance. Since the communication unit can be simplified, and the communicable distance of the wireless communication unit of the communication unit is short, the power consumption of the wireless communication unit is reduced. Even if the wireless communication unit of the communication unit is operated by the power of the dry battery stored in the unit, early consumption of the dry cell can be suppressed.

  In short, according to the monitoring system of the present invention, the communication unit can be simplified, and early consumption of the dry battery stored in the battery storage unit can be suppressed.

  A further characteristic configuration of the watching system according to the present invention is that the relay wireless communication unit is provided in a gas leak alarm installed at a location where the gas stove is installed.

  That is, the wireless communication unit of the communication unit communicates with the relay wireless communication unit provided in the gas leak alarm installed at the place where the gas stove is installed (for example, kitchen), and the relay wireless communication And the mobile terminal held by the external supervisor communicate via the external communication unit.

  That is, in recent years, for the purpose of notifying a gas management company of the occurrence of an abnormality such as a gas leak to a gas leak alarm installed at a location where the gas stove is installed (for example, a kitchen, etc.) By using the fact that the wireless communication unit of the communication unit is communicated with the wireless communication unit for relay provided in the gas leak alarm device, the gas stove use information is externally monitored. Communication with a portable terminal held by the person.

  In short, according to the further characteristic configuration of the watching system of the present invention, the gas stove use information can be communicated to the portable terminal held by the external monitor with a simple configuration that effectively uses the existing configuration.
