Description

  The present invention relates to a heating device such as a cooking device.

  Conventionally, the heating means, the operating means for operating the heating means, the control means for controlling the heating means in accordance with the operation of the operating means, the wireless remote control for transmitting a remote control signal, and the wireless remote control A receiving unit that receives a remote control signal, and the control means is known to be a cooking heating device that performs predetermined control on the heating means when the remote control signal is received by the receiving unit ( For example, see Patent Document 1).

  According to such a heating apparatus, when the receiving unit receives a remote control signal transmitted from the wireless remote controller, the control unit performs predetermined control on the heating unit. Here, the predetermined control is, for example, stopping the heating operation of the heating means. In this way, even when the user is away from the side of the heating device, the heating device can be immediately stopped using the wireless remote controller even in an emergency such as a spilled or burned dish. It can be performed.

  In such a heating device, in order to always receive a remote control signal, the receiving unit is always driven, that is, a drive current is passed. Therefore, in the case of a heating device that uses a battery as a power source, such as a portable or tabletop stove, there is a problem that the battery is consumed quickly.

  Therefore, it is conceivable that the receiving unit is not driven at all times but is driven intermittently for a predetermined time every predetermined time. In this case, the wireless remote controller outputs the remote control signal for a time longer than the predetermined time, so that the receiving unit can receive the remote control signal.

However, in this way, depending on the timing of operating the wireless remote controller, the remote controller signal transmitted from the wireless remote controller is delayed by a predetermined amount of time until the receiver receives the remote controller signal. May occur. As a result, when an emergency is required, for example, when spilling or burning may occur, even if a remote control signal for urgently stopping the heating is transmitted, there is a possibility that it is too late due to the delay. On the other hand, if the predetermined time, that is, the time during which the receiving unit is not driven is shortened, the effect of suppressing battery consumption is lost.

  An object of the present invention is to provide a heating apparatus that can be operated with a wireless remote controller as described above, and that can satisfy the two requirements of current consumption suppression and quick operation with the wireless remote controller.

To achieve the above object, the present invention transmits a heating means, an operation means for operating the operation of the heating means, and control means for controlling the heating means in response to operation of the operation means, the remote control signal comprising a wireless remote control, and a receiving unit that receives a remote control signal transmitted by wireless remote control, said control means performs a predetermined operation on the heating means in response to the remote control signal received by the receiving unit In the heating device, the temperature detecting means for detecting the temperature of the object to be heated by the heating means, and the receiving unit intermittently at a predetermined cycle c until the temperature detected by the temperature detecting means reaches a predetermined temperature. driven, characterized in that it comprises a reception control means for extending the time d in which the temperature is to drive the shorter the predetermined period c or the receiving unit when it is above the predetermined temperature.

In the heating apparatus of the present invention , the reception unit is intermittently driven at a predetermined period c until the temperature detected by the temperature detection unit reaches a predetermined temperature by the reception control unit. When the temperature detected by the temperature detection means becomes equal to or higher than a predetermined temperature, the period c is shortened or the time d for driving the receiving unit (hereinafter referred to as drive time) is extended . For example, in the urgent situation to the control of the heating means, the period c is set shorter, or the driving time d is set longer, otherwise the cycle c is set longer, or the drive time d is shorter The

  By doing in this way, the heating device of the present invention ensures responsiveness to the operation by the wireless remote controller in a situation where control is urgent, and in a situation where urgency is not required, the receiving unit is set within a predetermined period c. The current consumption is suppressed by non-driving in the time excluding the driving time d.

Also, timing in the heating apparatus of the present invention, includes a timing means for performing timed than a predetermined time in a heated state by the heating means, the control means, after the temperature becomes equal to or higher than the predetermined temperature, by the time measuring means When the given time t is equal to or longer than a predetermined time, the heating by the heating means may be stopped .

  The heating apparatus of this embodiment is a gas stove provided with a gas burner as a heating means. As shown in FIG. 1, the gas stove 1 includes a gas combustion unit 2, a main body operation panel 3 as operation means for performing operation control such as ignition / extinguishing and heating power adjustment of the gas combustion unit 2, and the main body operation panel 3. And a control means 4 for controlling the operation of the gas burner according to the operation. Further, the gas stove 1 includes a wireless remote controller 6 and an infrared signal receiver 7.

  Although not shown, the gas combustion unit 2 includes a gas burner, a gas supply passage for supplying fuel gas to the gas burner, and a plurality of valves such as a safety valve and a gas flow rate adjustment valve provided in the gas supply passage. The main body operation panel 3 includes various operation switches such as an ignition / fire extinguishing switch and a heating power adjustment knob, and a switch for selecting a cooking mode, for example, a kettle mode.

  Moreover, the gas stove 1 of this embodiment is provided with the temperature sensor 8, This temperature sensor 8 detects the temperature of the to-be-heated object heated by the gas combustion part 2, and this detected temperature data is the control means 4 Output toward.

  The control means 4 includes a timer 9 and a combustion control unit 10. The timer 9 starts counting from a predetermined time in the heating state by the gas combustion unit 2. The combustion control unit 10 controls the gas burner such as ignition / extinguishing and heating power adjustment in accordance with the operation by the main body operation panel 3.

  The wireless remote controller 6 includes, for example, a push button type switch 11 for stopping heating, and transmits an infrared signal as a remote control signal by pressing the switch 11. The infrared signal receiver 7 receives the infrared signal transmitted from the wireless remote controller 6 and outputs the received data of the received infrared signal toward the control means 4. When the received data is input, the control means 4 causes the combustion control unit 10 to extinguish the gas burner.

  Further, in the gas stove 1 of the present embodiment, the control means 4 further includes a reception control unit 12. The reception controller 12 intermittently drives the infrared signal receiver 7 with a predetermined period c, and changes the period c based on the temperature data detected by the temperature sensor 8 and the time t measured by the timer 9. To do.

  Next, the action | operation of the gas stove 1 which is a heating apparatus of this embodiment is demonstrated.

  With reference to FIG. 1, when cooking with the gas stove 1 of this embodiment, a user operates the main body operation panel 3, and performs ignition and thermal power adjustment. The control means 4 controls the gas combustion unit 2 via the combustion control unit 10 according to the operation of the main body operation panel 3. During this time, the user performs cooking work on the gas stove 1 side in order to adjust the heating while checking the state of the food. When cooking is completed, the user operates the main body operation panel 3 to extinguish the fire.

  By the way, even if the user is cooking, the user may be forced to leave the gas stove 1 side. Furthermore, if the spilled or burnt food is generated while the user is away from the gas stove 1, the user needs to immediately stop the operation of the gas stove 1 (extinguish the gas burner).

  Thus, when it is determined that there is a high possibility that an emergency operation is required to prevent the spilled or burnt food, the gas stove 1 according to the present embodiment sets the period c in advance when the infrared signal receiving unit 7 is driven. When the user performs an operation of pressing the switch 11 of the wireless remote controller 6 by setting it short or setting the drive time d within the period c long, the operation of the gas stove 1 is immediately stopped (fire the gas burner). can do.

  Next, a case where the “water heater mode” is selected as the first operation of the gas stove 1 will be described.

  In the “water heater mode”, a boiling determination condition for determining the boiling state is set, and when the set boiling determination condition is satisfied, the heating power of the gas stove 1 is adjusted to “weak” and maintained for a predetermined time. .

First, after the cooking utensil containing water is placed on the upper part of the gas combustion unit 2, the operation of the gas stove 1 is started and the gas burner is ignited in STEP 1 as shown in FIG. At this time, the heating power of the gas burner is “strong” as shown in FIG. Next, in STEP 2, the infrared signal receiver 7 is driven by the reception controller 12. At this time, the infrared signal receiving unit 7 receives the infrared signal within the period c _1a in which the period c is c _1a (for example, 700 milliseconds) and the driving time d is d _1a (for example, 200 milliseconds). The non-driving time of the unit 7 is 500 milliseconds). The temperature of the cooking utensil detected by the temperature sensor 8, the period c, and the driving time d are collectively shown in FIG.

Next, in STEP 3, when the “hot water” switch provided on the main body operation panel 3 is pressed by the user, the time t of the timer 9 is reset (t = 0) in STEP 4, and then in STEP 5, the timer 9 Starts timing.
Then, in STEP6, the temperature T of the cooking utensil, which is detected by the temperature sensor 8 is a predetermined temperature _{T 1} (e.g., 90 ° C.) is reached, the process proceeds to STEP7, the boiling determination is started. After that, since water is just before boiling, it is considered highly likely that spilling will occur. Therefore, in STEP 8, the cycle c of the infrared signal receiving unit 7 is shortened to c _1b (for example, 400 milliseconds) (that is, the non-driving time of the infrared signal receiving unit 7 in the cycle c _1b is 200 milliseconds). .
Next, in step 9, boiling condition determination is performed. Here, when the temperature T reaches a determination temperature, for example, 100 ° C. and is maintained for, for example, 3 seconds or more, it is determined that the boiling determination condition is satisfied. If it is determined in STEP 9 that it is boiling , the time t of the timer 9 is reset in STEP 10 (t = 0), and then in STEP 11 the timer 9 starts counting again.
Thereafter, in STEP 12, the combustion control section 10 makes the heating power of the gas burner "weak" as shown in FIG. As a result, since it is considered that the possibility of spilling is small, the period c is extended to c _1c (for example, 700 milliseconds) in STEP 13 (that is, the non-driving time of the infrared signal receiving unit 7 in the period c _1c is 500 milliseconds).
Thereafter, if the time t of the timer 9 is greater than or equal to a predetermined time t ₁ (for example, 5 minutes) in STEP 14, the process proceeds to STEP 15 and the gas burner is extinguished.

Although the cycle c _{1c is set} to 700 milliseconds as the first operation of the gas stove 1 of the present embodiment, the period is not limited to this, and may be longer than that, for example, 800 milliseconds.

  Next, as the second operation of the gas stove 1 according to the present embodiment, a case where it is in the “high cut temperature control mode” will be described.

Here, the “high cut temperature adjustment mode” means that the temperature detected by the temperature sensor 8 during cooking is maintained at a temperature lower than a preset temperature T ₂ (for example, 250 ° C.). This is a function for switching the strength of the gas burner, and this mode is usually selected.

  First, after placing the cooking utensil on the upper part of the gas combustion section 2, as shown in FIG. 4, the operation of the gas stove 1 is started, and the gas burner is ignited in STEP21. At this time, the heating power of the gas burner is “strong” as shown in FIG.

Next, in STEP 22, the infrared signal receiver 7 is driven by the reception controller 12. At this time, the infrared signal receiving unit 7 has a period c of c _2a (for example, 700 milliseconds) and a drive time d of d _2a (for example, 200 milliseconds) (that is, infrared signal reception within the period c _2a ). The non-driving time of the unit 7 is 500 milliseconds). Next, in STEP23, the time t of the timer 9 is reset (t = 0), and then the timer 9 starts measuring time as STEP24. The temperature of the cooking utensil detected by the temperature sensor 8, the period c, and the driving time d are collectively shown in FIG.

Next, when the temperature T of the cooking utensil reaches T ₂ (for example, 250 ° C.) by the temperature sensor 8 in STEP 25, the process proceeds to STEP 26 and high cut temperature control is started. While the high cut temperature control is operating, it is considered that the cooking utensil is in a high temperature state and the user is likely to perform an operation to extinguish the fire with the wireless remote controller 6. Accordingly, in STEP 27, the cycle c of the infrared communication receiver 7 is shortened to c _2b (for example, 400 milliseconds) (that is, the non-drive time of the infrared signal receiver 7 in the cycle c _2b is 200 milliseconds). . Thereafter, if the time t of the timer 9 is greater than or equal to a predetermined time t ₂ (for example, 30 minutes) in STEP 28, the process proceeds to STEP 29 and the gas burner is extinguished.

  In the first and second operations of the gas stove 1 according to the present embodiment, the case where the cycle c is changed according to the heating state has been described. However, both the first and second operations are alternatives to changing the cycle c. In addition, the driving time d may be changed.

  The third operation of the gas stove 1 at this time will be described as an example based on the case of the “high cut temperature control mode” described in the second operation.

The third operation is that in STEP 27, the period c is kept unchanged as c _2a and the driving time d is set to d _3b (for example, 400 milliseconds) (that is, the non-operation of the infrared signal receiving unit 7 within the period c _2a ). This is exactly the same as the second operation except that the driving time is 300 milliseconds. The temperature of the cooking utensil detected by the temperature sensor 8 at the time of the third operation, the period c, and the driving time d are collectively shown in FIG.

In the gas stove 1 of the present embodiment, the infrared signal receiver 7 is driven after STEP 2 in the first operation, and after STEP 22 in the second and third operations, so the switch 11 of the wireless remote controller 6 is turned on. By operating, heating can be stopped at any time (gas burner is extinguished). At this time, when it is determined by the user that it is necessary to immediately stop the operation of the gas stove 1 (fire extinguishing the gas burner), the reception control unit 12 causes the infrared signal reception unit 7 to have a cycle c _1b , shorter than normal. Since the non-driving time is shortened by driving with c _2b or driving with the driving time d _3b longer than usual, the responsiveness can be ensured.

  In each operation of the gas stove 1 of the present embodiment, the period c may be changed and the drive time d may be changed according to the heating state. Moreover, according to a heating condition, the period c and the drive time d may be set to the same time, and the infrared signal receiver 7 may be continuously driven.

  Moreover, although the gas stove 1 of this embodiment demonstrated the operation | movement in the case of the "water heater mode" and the "high cut temperature control mode" as an example, it is not limited to these modes.

  In the control means 4 of this embodiment, the example which performs the control which extinguishes a gas burner by using the wireless remote control 6 was shown, but it is not restricted to a fire extinguishing, For example, you may make it perform the control which reduces a thermal power Good.

  Moreover, in the gas stove 1 of this embodiment, after transmitting an infrared signal by the wireless remote controller 6, a notification means for notifying by sound or light that the infrared signal is surely received by the infrared signal receiver 7 is provided. You may prepare.

  Moreover, although the thing using an infrared signal was shown in the gas stove 1 of this embodiment, it is not restricted to this, You may use a radio signal.
