[Patent Document 1] Japanese Unexamined Patent Publication No. 2004-205177

By the way, the above voice guide can be performed by using voice IC, and the voice guide for attention ventilation is recorded in voice IC, and when the attention ventilation factor occurs, voice guide is output from voice IC and amplified by the speaker. If outputted, attentional ventilation by a voice guide can be performed. If you record the beep sound in the voice IC, you may be alerted by the beep sound.

However, these voice guides and beep-by-beep ventilation systems require a large current flow to the voice circuit to operate the voice IC or the speaker, so that the current consumption is larger than the method of displaying a text message on the liquid crystal display. For this reason, in the gas stove where batteries are used as a power source, the battery life is rapidly decreased, and it is inappropriate to adopt a careful ventilation method by sound.

In addition, the voice guide is convenient for users who are temporarily away from the gas stove during cooking or for elderly users, but it is not necessary for those who feel that the voice guide is bothersome and cumbersome. .

An object of the present invention is to provide a gas furnace which makes it possible to reduce the exhaustion of a battery, which is a furnace power supply, in consideration of the above problems.

In order to achieve the above object, the gas furnace having the attention ventilation function according to the present invention is a gas furnace having the attention ventilation function by sound, and when the battery is a furnace power supply, the furnace main body is provided with a voice guide. Equipped with a voice IC guide means and a piezoelectric buzzer means for careful ventilation with a buzzer sound, and when the attention ventilation factor occurs, the piezoelectric buzzer means or the piezoelectric buzzer means and voice Both of the IC guide means are activated.

In the present invention, when the attention ventilation factor occurs, the attention ventilation is performed by the buzzer sound by the piezoelectric buzzer or the voice guide by the piezoelectric buzzer sound and the voice IC according to the kind of the attention ventilation factor. In this case, due to the operation characteristics of the gas stove, the frequency of attention ventilation factors that can be solved with a buzzing sound, such as ignition / digestion operation of the stove, increase / decrease operation of the timer time, operation of increasing or decreasing the set temperature, etc. Since the current consumption is lower and the operating voltage is lower than that of the IC and the speaker, the piezoelectric buzzer is installed in addition to the voice IC guide means to allow careful ventilation by the piezoelectric buzzer. Even if the battery voltage is lower than the rated voltage, the gas cooker can be safely used for a long time by careful ventilation by the piezoelectric buzzer.

In addition, as a voice mode for performing careful ventilation by sound, a voice mode for operating both the voice IC guide means and the piezoelectric buzzer means, and a silent mode for operating only the piezoelectric buzzer means are formed so as to be switchable. In the case of selecting, the piezoelectric buzzer is operated irrespective of the type of the attentional ventilation factor, thereby reducing the battery consumption and enabling the user to perform the attentional ventilation by sound, and further extend the battery life.

In addition to switching between the audio mode and the silent mode by manual selection, when the battery voltage is reduced below a predetermined voltage, the audio mode and the silent mode can be switched by the automatic selection. When the battery voltage falls below a predetermined voltage, the voice mode is automatically switched to the silent mode, and only a piezoelectric buzzer is used to carefully ventilate the sound. I can do it.

Below the handle 11-13 of the right front of the furnace main body 4, the sheet-shaped operation panel 18 in which the operation switch was formed by the seat key is formed, and the said operation panel 18 is the cover 18a of the front end part. When press-fitting, the locking means is released and the door is protruded forward by the force of the spring.

In the operation panel 18, switches and display lamps for setting the heating temperature / heating time of the furnace burners 6 to 8, the selection of cooking contents, and the like, and the automatic / manual firing of the grill burner 9 A switch, a display lamp, and the like for selecting a composition, selecting a kind of fired material in automatic firing, and the like are formed, and a voice switch and a display lamp (voice lamp) are formed. In FIG. 1, a voice switch is indicated by a reference numeral 19.

The voice switch 19 is a voice mode for performing a careful ventilation. The voice switch 19 is used to selectively switch between a voice guide mode for performing a careful ventilation by a voice guide and a piezoelectric buzzer and a silent mode for performing a careful ventilation with only a piezoelectric buzzer. will be. Each time the voice switch 19 is pressed, the voice mode alternates between the voice mode and the silent mode, so that the user can see, the voice lamp is turned on in the voice mode mode selected, and the voice is turned on in the voice mode selected mode. The lamp goes out. In the present invention, as described above, attention ventilation by the piezoelectric buzzer or attention ventilation by the piezoelectric buzzer and the voice guide is performed according to the type of the attention ventilation factor, and when the silent mode is selected, any kind of attention ventilation factor is selected. Irrespective of the fact, it is a feature to perform careful ventilation with only a piezoelectric buzzer.

The schematic structure of the gas circuit and the control electric circuit of this gas furnace 1 is shown in FIG. As shown in FIG. 2, the gas circuit 20 of the gas furnace 1 branches off the downstream side of the circular valve 21 and passes through the solenoid safety valve 22 and the flow regulating electric valve 23, respectively. It is connected to the furnace furnace burners 6-8 and the grill burner 9. As shown in FIG. In the vicinity of each of the furnace burners 6 to 8, an ignition electrode 24 for igniting the burner by flame discharge, a flame detection sensor 25 for monitoring the burner's combustion, the pot bottom temperature sensor 15, , Pot detection sensor 16 is formed. An ignition electrode 24 and a flame detection sensor 25 are also formed in the vicinity of the upper and lower grill burners 9.

As shown in FIG. 3, the electric circuit 30 for controlling the gas furnace 1 includes a control circuit 40 connected to a battery 41, which is a furnace power supply, via a boosting circuit 42. 40 is connected to the battery 41, an igniter 43, a piezoelectric buzzer 44, and a battery voltage monitoring device 50, and a voice IC (connected to the battery 41 through a booster circuit 42). 45 is connected, and the audio IC 45 is connected to the audio amplification circuit 46 connected to the battery 41 through the normally closed output contact type relay 47 and the booster circuit 42. The speaker 48 is connected to the amplifying circuit 46. The control circuit 40 is also connected with a reset circuit 49 connected to the battery 41 via a boosting circuit 42.

The voice IC 45, the voice amplifier circuit 46, and the speaker 48 constitute voice IC guide means (abbreviated voice guide means), and the voice IC guide means includes a voice attention factor generated by the voice guide. It works when it's the kind that does. That is, the voice IC 45 selects and outputs a voice guide according to the type of the attention ventilation factor by the signal from the control circuit 40, and amplifies it by the voice amplifier circuit 46 to apply the speaker 48. The voice guide is outputted from the speaker 48 by printing. The piezoelectric buzzer 44 constitutes a buzzer means together with the switching transistor 44a of the previous step, and operates regardless of its type when a careful ventilation factor occurs, and is switched by a signal from the control circuit 40. The buzzer sound is output by turning on / off the 44a and driving the piezoelectric buzzer 44 by the output of the transistor 44a which is operated on / off.

In order not to operate the voice guide means, by the signal from the control circuit 40, the switching transistor 47a of the step before the relay 47 is turned ON to send a current to the relay 47 to open a contact. The connection between the voice amplifier circuit 46 and the battery 41 is cut off, and the voice amplifier circuit 46 and the speaker 48 are not operated. The audio IC 45 is set to an operating state by applying a reset output to the control circuit 40 to this.

In addition, the control circuit 40 detects the detection signals of the gas burners 6 to 9 flame detection sensor 25 and the detection signals of the pot bottom temperature sensor 15 and the pot detection sensor 16 of the burners 6 to 8. Is input, and the respective detection signals of the ignition monitoring sensor 26 and the rotation amount sensor 27 of the operation knobs 11 to 14 are inputted, and the control valve 40 supplies the one-valve 21 of the gas circuit, The electromagnetic safety valve 22 and the electric flow rate valve 23 for adjusting the flow rate are controlled.

In this gas furnace 1, when the operation handle 11 of the burner 6 is press-fitted in order to use the burner 6 of the left side, for example in the gas burners 6-9, it shows by the press-fitting. The ignition monitoring sensor 26 detects that the omitted spring mechanism is moved to protrude forward and the ignition operation is performed. The detection signal is input to the control circuit 40, and the control circuit 40 sends an operation signal. The output valve opens the original valve 21 and the solenoid safety valve 22, and repeatedly opens and maintains the electric valve 23 at a predetermined opening degree. Thereafter, the switching transistor 43a of the stage before the igniter 43 is turned ON, the igniter 43 is operated for a predetermined time, and the spark is discharged from the ignition electrode 24 of the burner 6 to burn the burner ( Light 6). When the burner 6 is ignited and burned, the flame detection sensor 25 detects the combustion flame, and the detection signal of the flame detection sensor 25 is continuously input to the control circuit 40, whereby the burner ( 6) Ignition completion or off after commencement of combustion is monitored.

Then, the control circuit is operated in the event of a careful ventilation factor for safety, combustion situation, cooking progress situation, etc. from the ignition of the burner 6 to the start of cooking, the completion of cooking and the extinguishing of the burner 6. The 40 sounds the piezoelectric buzzer 44 to perform a careful ventilation, and according to the type of the attention ventilation factor, a voice guide corresponding to the situation is selected from the voice IC 45, and this is a voice amplification circuit 46 and a speaker. Output through (48), careful ventilation also by the voice guide.

In the present invention, "attention ventilation" means not only appealing for safety, combustion, cooking progress, etc., to prompt the user for check and confirmation, and in some cases, to promote appropriate measures. In the case of the voice guide, it also means instructing the user to complete the cooking or the work to be processed during the cooking.

Some examples of the voice guide include, for example, whether or not the burner 6 is ignited. If the ignition succeeds, the speaker 48 outputs a voice guide saying "The burner is burned to the left corner," and the ignition fails. You will hear a voice guide saying `` Failed to ignite left burner ''. In addition, when the pot bottom temperature sensor 15 detects the temperature of the pot boiling water on the burner 6 and the detection temperature reaches the boiling temperature, a sound guide is outputted. do. When the burner 6 is turned off by the flame detection sensor 25, a sound guide for notifying the effect is output.

By the way, in order to operate the voice IC guide means, i.e., the voice IC 45 or the speaker 48, it is necessary to send a current to the voice circuit, so that the current consumption is large and the battery capacity of the battery 41 is large. The service life deteriorates quickly. Therefore, in the present invention, as described above, as a voice mode for performing careful ventilation by sound, in addition to the voice mode performed by both the voice guide and the piezoelectric buzzer, a non-voice mode using only the piezoelectric buzzer is formed, and the operation panel 19 Voice switch 18 allows the user to switch between the audio mode and the silent mode, and when the silent mode is selected, regardless of the type of attentional ventilation caused, did. Further, the battery voltage monitoring device 50 that monitors the voltage of the battery 41 (in this embodiment, the series connection of two single batteries) is below a predetermined drop voltage, for example, less than 2.7 V at a rated 3V. When the detected drop is detected, the control circuit 40 recognizes this by the detection signal and automatically selects the silent mode. In addition, what is necessary is just to determine suitably the said predetermined fall voltage according to the relationship with the load on a battery, and it is not limited to 2.7V.

If the voice mode is switched by manual selection by the voice switch 19 or by automatic selection due to a drop in battery voltage, the control circuit 40 switches to the mode for selecting the voice mode stored in the built-in memory. Then, it is determined whether the selected voice mode is a voiced or unvoiced mode, and the voice guide means is not operated when it is in the unvoiced mode.

According to the caution ventilation control having the voice mode as described above, by switching the voice mode to the silent mode with the voice switch 19, when the attention ventilation factor occurs, the voice by the voice IC guide means having a large current consumption. Because only the ventilation by the piezoelectric buzzer can be performed without using the guide, it is possible to reduce the consumption of the battery, which is the furnace power supply, to perform the careful ventilation by sound, to prolong the battery life, and to eliminate the sound guide. People who feel good can be freed from the hassle of voice guide. In addition, when the battery voltage decreases below a predetermined voltage, the voice mode is automatically switched to the silent mode in which the ventilation is performed only by the piezoelectric buzzer 44, so that the careful ventilation by sound can be performed without ending the short time. .

Hereinafter, the attentional ventilation control by sound of this embodiment is demonstrated by the flowchart shown in FIG.

In FIG. 4, when the voltage of the battery 41 detected by the voltage monitoring device 50 in step Sl is 2.7 V or more, which is a predetermined drop voltage, the voice stored in the memory of the control circuit 40 in step S2. It is judged whether the mode is the voiced mode or not. In the voiced mode, it is determined whether or not the voice switch 19 is pressed in step S3. If it is pressed, it is determined that the silent mode is selected. The process goes from the audio mode to the silent mode, and the flow goes to step S9. If it is determined in step S3 that the audio switch is not pressed, the flow proceeds directly to step S9.

When the voice mode of the memory is determined as the silent mode in step S2, it is judged whether or not the voice switch is pressed in step S5. If it is pressed, it is determined that the voice mode is selected and the voice mode in the memory is changed to the voice mode in step S6. After switching, the process goes to step S9, and when it is determined that the audio switch is not pressed, the flow goes to step S9 as it is.

When it is detected in step Sl that the battery voltage is less than 2.7 V, it is determined in step S7 whether or not the voice mode stored in the memory is in the voiced mode. In the case of the voiced mode, the voice mode in the memory is turned off in step S8. The audio mode is switched to and step S9 is reached. If it is determined in the silent mode in step S7, the flow goes to step S9 as it is.

In step S9, it is determined whether or not the attention ventilation factor has occurred, and if no attention ventilation factor has occurred, the process returns to step S2, and when the attention ventilation factor has occurred, the contents of the attention ventilation factor are determined in step S10 and the piezoelectric It is judged whether only the buzzer sound of the buzzer 44 is made, and when it is determined that only the buzzer sound is made, the piezoelectric buzzer 44 is operated in step Sll to perform careful ventilation. If it is determined in step S10 that the contents of the attention ventilation factor are judged to be a kind of voice guide, in step S12, the attention ventilation is first performed by the piezoelectric buzzer, and then in step S13, the voice mode stored in the memory is the voice mode. If it is judged whether or not, and in the voiced voice mode, the voice guide means is operated in step S14, and attention ventilation by the voice guide according to the contents of the attention ventilation factor is performed. If it is determined in the silent mode in step S13, the flow returns to step S2.

As apparent from the above embodiment, according to the present invention, attentional ventilation by sound can be performed by reducing consumption of a battery which is a furnace power supply, and battery life can be extended.
