Description

The present disclosure relates to gas stoves.

The gas stove disclosed in Patent Literature 1 includes a burner, a stove control circuit, and a wireless communication section. The stove control circuit has a function of automatically turning off the gas stove when it is determined that the burner is unlikely to be used. The gas stove wirelessly transmits and receives operating conditions for automatic cooking such as recipe data selected and set by the mobile terminal and the operating state of the gas stove to and from the mobile terminal via the wireless communication unit. The stove control circuit does not automatically turn off the power of the gas stove when communication is being performed with the portable terminal regardless of whether the possibility of using the burner is low.

JP 2018-40515 A

However, in the gas stove of Patent Document 1, the power of the gas stove remains on even when the burner is not in use while communication is being performed with the portable terminal. Therefore, the gas stove continues to consume power while communication is being performed with the portable terminal. This causes a problem of increased power consumption of the gas stove.

In order to solve at least one of the problems described above, the present disclosure provides a technology that can effectively reduce power consumption in a gas stove that can wirelessly communicate with an external device.

A gas stove, which is one of the present disclosure,
a heating unit that heats an object to be heated;
a wireless communication unit that performs wireless communication with an external device;
A gas stove comprising
A power control unit for switching the gas stove between a power-on state and a power-off state,
The power control unit switches the gas stove from the power-on state to the power-off state when all predetermined use determination conditions are no longer satisfied while the wireless communication unit is performing wireless communication with the external device.

In the above gas stove, when the wireless communication unit is performing wireless communication with an external device and all of the predetermined use determination conditions are no longer satisfied, the power of the gas stove can be switched from the power-on state to the power-off state. By doing so, it is possible to prevent a situation in which the continuation of wireless communication is prioritized and the power-on state is maintained when all of the predetermined usage determination conditions are no longer satisfied. Therefore, power consumption can be reliably suppressed after all of the predetermined usage determination conditions are no longer satisfied.

In the above-described gas stove, the usage determination condition may include a condition that a certain period of time elapses after a predetermined instruction is given to the gas stove.
If a certain period of time has passed since a predetermined instruction was issued to the gas stove, the possibility that the gas stove has not been used increases. In such a case, the gas stove can be automatically switched to the power-off state if other use determination conditions are not met, thereby effectively reducing power consumption. On the other hand, since the use determination condition is satisfied until a certain period of time has elapsed since a predetermined instruction was given to the gas stove, it is possible to prevent the gas stove from switching to the power off state.

In the gas stove described above, the usage determination condition may include a condition that a certain period of time elapses after the specific command is transmitted to the gas stove by wireless communication.
In this gas stove, it is possible to prevent the power from being switched to the power-off state until a certain period of time has elapsed since the transmission of the specific command. On the other hand, if a certain period of time has passed since the transmission of the specific command, the possibility that the gas stove is not being used increases. In such a case, the gas stove can be automatically switched to the power-off state if other use determination conditions are not met, thereby effectively reducing power consumption.

In the above-described gas stove, the usage determination condition may include a condition that a certain period of time elapses after the end of the cooking period in the automatic cooking mode.
Since it is possible to prevent switching to the power off state until a fixed time elapses from the end of the cooking period in the automatic cooking mode, it is advantageous when the power of the gas stove should be maintained immediately after the end of the cooking period in the automatic cooking mode. On the other hand, if a certain period of time has passed since the end of the cooking period in the automatic cooking mode, the possibility that the gas stove is not being used increases. In such a case, the gas stove can be automatically switched to the power-off state if other use determination conditions are not met, thereby effectively reducing power consumption.

The gas stove described above may be a battery-powered gas stove in which internal electrical components operate based on power from a battery.
When a battery-type gas stove is configured to enable wireless communication, there is a concern that the power consumption caused by wireless communication will lead to early replacement of the battery. However, by adopting the above feature, the power consumption of the battery can be reliably reduced when the user does not use the gas stove, and the early replacement of the battery can be prevented.

In each of the rotary operation units 6A, 6B, 6C, and 6D, the displacement (rotational position) of the rotary operation unit is detected by the corresponding displacement detection unit, and a signal corresponding to the displacement (rotational position) detected by the displacement detection unit is supplied to the control circuit 10 from the thermal signal input circuit corresponding to the displacement detection unit.

2 and 3, thermocouples 51C, 52C, 53C, 54C and 54D are provided adjacent to the burners 51, 52, 53, 54A and 54B, respectively, and temperature signal input circuits 44A, 44B, 44C, 44D and 44E are provided corresponding to the thermocouples 51C, 52C, 53C, 54C and 54D, respectively. Each of the temperature signal input circuits 44A, 44B, 44C, 44D and 44E inputs to the control circuit 10 a signal corresponding to the electromotive force generated by the corresponding thermocouple. Igniters 26A, 26B, 26C and 26D are provided adjacent to the gas burners 51, 52, 53 and 54, respectively, and igniter circuits 46A, 46B, 46C and 46D are provided corresponding to the igniters 26A, 26B, 26C and 26D, respectively. For example, an igniter 26D is provided corresponding to the gas burner 54, and the igniter circuit 46D drives the igniter 26D in response to an external ignition operation (ignition operation of the switch 30D) to the rotary operation unit 6D, and the igniter 26D discharges a spark to ignite the gas burner 54.

The operation panel 18 is configured as an operation panel having a plurality of buttons, so that various information can be input according to the user's operation.

The control circuit 10 is configured as a microcomputer, for example, and includes a CPU 10A, a ROM 10B, a RAM 10C, etc. as shown in FIG. Also, although not shown, a non-volatile memory may be provided inside or outside the control circuit 10 .

The control circuit 10 corresponds to an example of a heating control section, and controls the gas burners 51, 52, 53, 54, electromagnetic valves, igniters 26A, 26B, 26C, 26D, etc. Specifically, it controls the ignition and extinguishing of the gas burners 51, 52, 53, 54 and the heating power of each gas burner in accordance with the operations performed on the four rotary operation sections 6A, 6B, 6C, 6D. The control circuit 10 can also control a plurality of display devices 21, 22, 23, 24, an audio device 14, and the like. The audio device 14 is a device that emits sounds such as melodies and messages.

The gas stove 1 is a battery-powered gas stove in which internal electrical components operate based on electric power from dry batteries 49 . The power supply circuit 48 has a function of receiving power from two dry batteries 49 housed in a battery box and generating a predetermined power supply voltage, and the power supply voltage generated by the power supply circuit 48 is supplied to various electrical components via paths (not shown).

The control circuit 10 corresponds to an example of a power supply control unit, and functions to switch the gas stove 1 from a predetermined power-on state (equipment power-on state) to a predetermined power-off state (appliance power-off state) when a non-use condition, which will be described later, is satisfied while the gas burners 51, 52, 53, and 54 are not heating.

The communication unit 92 is a communication circuit for performing wireless communication by pairing with a mobile terminal (external device) 100, which will be described later. The communication unit 92 and the control circuit 10 to be described later correspond to an example of a wireless communication unit, and perform wireless communication with the mobile terminal 100 . The communication unit 92 is a device capable of wirelessly communicating with the mobile terminal 100 by a known wireless communication method (for example, a communication method according to a known wireless communication standard such as Bluetooth (registered trademark) or Wi-Fi (registered trademark)).

As shown in FIG. 3, the mobile terminal (external device) 100 is configured as a mobile information processing terminal such as a smart phone or a tablet terminal, and can operate using a secondary battery (not shown) as a power source.

The mobile terminal 100 includes a control circuit 101, a memory 102, a communication section 103, a display section 104, an operation section 105, and the like. The control circuit 101 is configured as, for example, a known information processing device such as a microcomputer, and includes a known arithmetic device such as a CPU and other peripheral circuits, and can perform various controls and calculations.

The memory 102 may be any device that can store information, and may be configured with a plurality of known semiconductor storage devices such as ROM, RAM, and nonvolatile memory, for example. The communication unit 103 is a communication device capable of wireless communication using a known wireless communication method (for example, a communication method conforming to a known wireless communication standard such as Bluetooth (registered trademark) or Wi-Fi (registered trademark)). The communication unit 103 can wirelessly communicate with the communication unit 92 of the gas stove 1 . The display unit 104 is, for example, a display unit that forms part of a known touch panel display device, and is configured as a known image display device such as a liquid crystal display or an organic electroluminescence display. The operation unit 105 may be configured to allow information to be input by a user's operation, and may include an input interface (such as a button) other than a touch panel.

Next, control of the gas stove 1 will be described.
The control circuit 10 controls the gas stove 1 to switch from the power-on state to the power-off state even when the wireless communication unit (the control circuit 10 and the communication unit 92) is communicating wirelessly with an external device when all of the predetermined use determination conditions are no longer satisfied when all the gas burners are in the extinguishing state. The usage determination conditions are a plurality of conditions determined for holding the power source (instrument power source) of the gas stove 1, and if at least one of the usage determination conditions is established, the operation of automatically switching from the power-on state to the power-off state is not performed.

In this configuration, the use determination condition (condition for holding the power supply (appliance power supply) of the gas stove 1) includes the condition that "a certain period of time (for example, 3 minutes) has elapsed since a predetermined instruction was given to the gas stove 1." The “predetermined instruction” here is an instruction predetermined as an instruction to the gas stove 1 .

In this configuration, the "predetermined instruction" includes a predetermined operation (predetermined operation performed by the user) externally performed on the operation section (operation on the rotary operation sections 6A, 6B, 6C, and 6D). This predetermined operation includes a pressing operation for ignition on any one of the rotary operation units 6A, 6B, 6C, and 6D, and a rotary operation for adjusting the heating power on any one of the rotary operation units 6A, 6B, 6C, and 6D. When these operations are performed, the use determination condition (condition for holding the appliance power supply) is satisfied at least until a certain period of time (for example, 3 minutes) has passed since the operation, and the power is not automatically turned off. Also, the "predetermined instruction" includes an instruction to extinguish the gas burner. In other words, when an operation to extinguish the corresponding gas burner is performed for any of the rotary operation parts 6A, 6B, 6C, and 6D, the use determination condition is satisfied until at least a certain period of time has passed since the operation, and the power is not automatically turned off. For example, when an operation to extinguish the gas burner 51 is performed on the rotary operation part 6A, the usage determination condition is satisfied at least until a certain time elapses from the operation, and the power is not automatically turned off.

Also, the “predetermined instruction” includes a predetermined operation performed on the operation panel 18 from the outside (predetermined operation performed by the user). This predetermined operation is to input information by operating one of a plurality of buttons provided on the operation panel 18, and when these operations are performed, the usage determination condition (condition for holding the appliance power supply) is satisfied at least until a certain period of time (for example, 3 minutes) has passed since the operation, and the power is not automatically turned off.

Further, the predetermined instruction includes a specific command given from the portable terminal 100 to the gas stove 1 by wireless communication. The specific command is a command predetermined as a command for causing the gas stove 1 to perform a specific operation (information instructing the gas stove 1 to perform a specific operation). Extinguishing operations of the gas burners 51, 52, 53, and 54 are examples of specific operations of the gas stove 1. FIG. When the gas stove 1 receives such a specific command through wireless communication, the usage judgment condition (condition for holding the power supply of the appliance) is established until a fixed time (for example, 3 minutes) has passed since the reception, and the power is not automatically turned off. Here, the fire extinguishing operation is exemplified as the specific operation of the gas stove 1, but the operation of changing the heating power of the gas burners 51, 52, 53, 54 (for example, the operation of reducing the heating power) may be used.

Thus, in this configuration, when the gas stove 1 (specifically, the wireless communication unit) receives predetermined specific information (specifically, a specific command) from the mobile terminal 100 via wireless communication, the power supply control unit does not switch from the power-on state to the power-off state until a certain period of time elapses from the reception of the specific information because the use determination condition is satisfied. On the other hand, when the gas stove 1 (specifically, the wireless communication unit) has not received the specific information, or after the predetermined time has passed since the gas stove 1 (specifically, the wireless communication unit) received the specific information, the power control unit switches from the power-on state to the power-off state unless other use determination conditions are satisfied even if information other than the specific information is wirelessly communicated between the portable terminal 100 and the wireless communication unit.

In addition, the use determination condition (condition for holding the power supply (appliance power supply) of the gas stove 1) includes the condition "until a predetermined time (for example, 3 minutes) has elapsed since the end of the automatic cooking mode ("toast mode", "dried fish mode", "slice mode", "sugar grill mode"). The end of the automatic cooking mode is a predetermined end timing, which may be the timing when the end of the automatic cooking mode is notified, or the timing when a certain period (preheating period) has passed after extinguishing the gas burner operating in the automatic cooking mode. Alternatively, other known end timings may be used. Due to such a configuration, until a certain period of time (for example, 3 minutes) has passed since the end of the automatic cooking mode, the use judgment condition (condition for holding the appliance power supply) is established, and the power supply is not automatically turned off.

The use determination condition (condition for maintaining the power source (appliance power source) of the gas stove 1) includes the condition "until a predetermined period (for example, 15 minutes) elapses after a predetermined error condition is established." Due to such a configuration, the use determination condition (condition for holding the power supply of the appliance) is satisfied until a predetermined period (for example, 15 minutes) has passed since the establishment of the predetermined error condition, and the power is not automatically turned off. The "predetermined error condition" referred to here may be, for example, "the occurrence of a predetermined error state such as an error state in which the temperature detected by a temperature sensor arranged at a predetermined position is equal to or higher than a threshold value (e.g., the threshold value for determining abnormal heating or higher), an error state in which a vibration sensor detects vibration, or an error state in which ignition does not occur during an ignition operation", or "in response to the occurrence of these error states, an error display indicating the type of the occurred error is started on the display unit".

In this configuration, the power supply control unit (control circuit 10) forcibly switches the gas stove 1 from the power-on state (appliance power-on state) to the power-off state (appliance power-off state) even if wireless communication is continuing when all of a plurality of predetermined use determination conditions are no longer satisfied while the wireless communication unit (control circuit 10 and communication unit 92) is performing wireless communication with an external device. As a result, the power supply to most of the electrical components that make up the gas stove 1 is cut off, and wireless communication is also cut off.

The power-on state (instrument power-on state) referred to here is a state in which the power lamp is lit, and for example, a state in which an operation on an operation unit other than the power button is accepted. In this power-on state, it is possible to perform ignition operation and heating power adjustment operation on the rotary operation units 6A, 6B, 6C, and 6D. The power-off state (instrument power-off state) is a state in which the power lamp is turned off, and for example, a state in which no operation is accepted on an operation unit other than the power button. In this power-off state, ignition operation and thermal power adjustment operation for the rotary operation units 6A, 6B, 6C, and 6D are disabled.

Even in the power-off state (instrument power-off state), power supply to the control circuit 10 is maintained when a predetermined system power supply maintenance condition is satisfied. On the other hand, power supply to the control circuit 10 is not performed in the power off state (instrument power off state) and when the system power supply maintenance condition is not satisfied. The system power maintenance conditions include when the power is on (equipment power is on), when a flame of any of the cos burners is detected by a flame detector (not shown), when any of the motors is operating, when the solenoid valve is operating, and when in the test mode.

The effect of this configuration is illustrated.
In the above gas stove 1, when the wireless communication unit (the control circuit 10 and the communication unit 92) is wirelessly communicating with the mobile terminal 100 and all the predetermined usage determination conditions are no longer satisfied, the gas stove 1 can be switched from the power-on state to the power-off state. By doing so, it is possible to prevent a situation in which the continuation of wireless communication is prioritized and the power-on state is maintained when all of the predetermined usage determination conditions are no longer satisfied. Therefore, power consumption can be reliably suppressed after all of the predetermined usage determination conditions are no longer satisfied.

The usage determination condition includes a condition that it is within a period of time from when a "predetermined instruction" is given to the gas stove 1 until a certain period of time elapses. If a certain period of time has passed since a predetermined instruction was given to the gas stove 1, the possibility that the gas stove 1 has not been used increases. In such a case, the gas stove 1 described above can automatically switch to the power off state if the other use determination conditions are not met, thereby effectively reducing power consumption. On the other hand, since the use determination condition is satisfied until a certain period of time has elapsed since a predetermined instruction was given to the gas stove 1, it is possible to prevent the gas stove 1 from switching to the power off state.

Further, the usage determination condition includes a condition that a certain period of time elapses after a specific command is transmitted to the gas stove 1 by wireless communication. Since this gas stove 1 can be prevented from switching to the power off state until a certain period of time elapses after the transmission of the specific command, it is advantageous when the power of the gas stove 1 should be maintained immediately after the transmission of the specific command. On the other hand, if a certain period of time has passed since the transmission of the specific command, the possibility that the gas stove 1 has not been used increases. In such a case, the gas stove 1 described above can automatically switch to the power off state if the other use determination conditions are not met, thereby effectively reducing power consumption.

Further, the usage determination condition includes a condition that it is within a period from the end of the cooking period in the automatic cooking mode to the elapse of a certain period of time. Since this gas stove 1 can be prevented from switching to the power off state until a fixed time elapses from the end of the cooking period in the automatic cooking mode, it is advantageous when the power of the gas stove 1 should be maintained immediately after the end of the cooking period in the automatic cooking mode. On the other hand, if a certain period of time has passed since the end of the cooking period in the automatic cooking mode, the possibility that the gas stove 1 is not being used increases. In such a case, the gas stove 1 described above can automatically switch to the power off state if the other use determination conditions are not met, thereby effectively reducing power consumption.

The gas stove 1 is configured as a battery-powered gas stove in which internal electrical components operate based on electric power from a battery (for example, a dry battery). When a battery-type gas stove is configured to enable wireless communication, there is a concern that the power consumption caused by wireless communication will lead to early replacement of the battery. However, if the above feature is adopted, the power consumption of the battery can be reliably reduced when the user does not use the gas stove 1, and the early replacement of the battery can be prevented.
