  49 is a color display provided in the shape of a horizontally long bar below the display unit 37 in the operation unit 2. During operation, the color display is lit in a green color with a visually reverse action, and the forgetting to turn off timer means 34 or Good morning timer means 35 blinks green for a certain time before automatic fire extinguishment, and when the remaining fuel amount becomes less than a predetermined amount and extinguishes fire by means of out of fuel extinguishing means 36, there is a visual advance action. By turning on and blinking red, which is the advance color, the user is encouraged to refuel with a more visible color.

  The color display 49 includes a light emitting unit 50 that emits red and green light and a diffusion lens 51 that diffuses the light from the light emitting unit 50 to the surroundings.

  The light emitting unit 50 has a shallow hole 52 formed in the operation unit 2, and two red LEDs 53 and three green LEDs 54 are alternately arranged in a horizontal row on the bottom, and the hole 52 is further formed. A diffusing lens 51 that is provided with a large number of quadrangular pyramid-shaped concave portions on the back surface and is made into a prism is fitted so that the operation unit 2 is flat.

Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS.
First, when the operation switch 38 is pressed (step 1, hereinafter abbreviated as S1), an on operation confirmation sound “beep” is emitted from the buzzer 48 (S2), and the operation lamp 46 provided in the operation switch 38 is turned on slowly. Flashing starts at (0.5 seconds on / 0.5 seconds off) (S3), energization of the vaporizing heater 26 is started and preheating of the vaporizer 25 is started (S4), and the operation is accepted by a confirmation sound. From the flashing state of the operation lamp 46, it can be seen that the carburetor 25 has entered the preheating state.

  Next, when preheating is completed by detecting the temperature at which the vaporization temperature sensor 27 can be ignited (S5), the green LED 54 of the color display 49 is turned on (S6), and the operation lamp 46 is changed from blinking to lighting ( S7), the combustion fan 23, the electromagnetic pump 20, the igniter 30, and the convection fan 5 are driven to perform an ignition operation (S8). In this way, the color indicator 49 is lit in a retreat color such as green or blue to indicate that combustion is being performed without being visually noisy.

  When the operation is started, the forgetting-off timer means 34 is operated to start the operation time counting (S9), and then it is checked whether the float switch 19 is turned on (S10).

  If the fuel amount has not decreased to the level at which the float switch 19 is turned on in S10, it is checked whether the count time of the forgetting-off timer means 34 has reached 15 minutes before the fire extinguishing time (S11), and 15 minutes of the fire extinguishing time. If it was before, the buzzer 48 generates a notification sound of “Peep-Peep” (S12), and the green LED 54 of the color display 49 blinks at a slow blinking cycle (2 seconds on / 1 second off) (S13). ), “OFF” is flashed on the segment of the display unit 37 displaying the room temperature (on for 0.5 seconds / off for 0.5 seconds) (S14), and the sound generated by the buzzer 48 and the color display 49 are displayed. The user can be surely informed that automatic fire extinguishing is near by the light by and the character display on the display unit 37.

  When the count time of the forget-to-extinguish timer means 34 reaches 10 minutes before the fire extinguishing time (S15), the buzzer 48 generates a notification sound “Peep Pea” again (S16), and automatic fire extinguishing is close. To the user.

  Further, when the count time of the forget-to-extinguish timer means 34 reaches 3 minutes before the fire extinguishing time (S17), the buzzer 48 again generates a notification sound "Spi" (S18), and the color display 49 The green LED 54 is changed from a slow blinking cycle to a fast blinking cycle (on for 1 second / off for 0.5 seconds) and blinked (S19). Can let you know.

  When the count time of the forget-to-extinguish timer means 34 counts the fire extinguishing time (S20), the buzzer 48 generates a beeping sound (S21) to inform that automatic fire extinguishing is performed. The green LED 54 and the operation lamp 46 of the color display 49 are turned off (S22, S23), the “OFF” character display on the display unit 37 is changed from the blinking state to the lit state (S24), and the combustion fan 23, electromagnetic The pump 20 and the convection fan 5 are stopped and fire extinguishing operation is performed (S25).

  After the fire extinguishing operation is performed, when the operation switch 38 is turned off (S26), a confirmation sound “pipi” for the off operation is generated from the buzzer 48 (S27), the “OFF” character display on the display unit 37 is turned off, The clock is displayed (S28). Thus, the “OFF” character display continues until the operation switch 38 is turned off, so that it is possible to know after the extinguishment that the operation of the device has been extinguished by the timer means 34.

  Next, a description will be given of the case where the remaining fuel amount in the fixed tank 18 is equal to or less than a predetermined amount and the float switch 19 is turned on in S10. The green LED 54 of the color display 49 is turned off (S30), and at the same time, the red LED 53 of the color display 49 starts to flash at a slow flashing cycle (2 seconds on / 1 second off) (S31). "Starts blinking (on for 1 second / off for 0.5 second) (S32).

  In this way, the display of the color indicator 49 is changed from green, which is the reverse color during normal operation, to red, which is the advance color, thereby visually indicating that the remaining fuel amount has been reduced more positively and clearly. Further, the sound from the buzzer 48, the light from the color display 49, and the letters “fuel supply” on the display unit 37 are surely notified to the user that automatic fire extinguishing due to running out of fuel is near, and fueling is encouraged.

  Next, counting of the number of drive pulses of the electromagnetic pump 20 is started (S33), and it is determined whether or not the counted number of pulses is equal to or greater than a predetermined value (S34). The predetermined number of pulses to be counted is set so that the fuel in the fixed tank 18 is not completely emptied, and the combustion can be continued for about 20 minutes with strong combustion and about 40 minutes with weak combustion.

  When the number of pulses counted here reaches a predetermined value (Yes in S34), the buzzer 48 generates a beeping sound continuously three times (S35), and the red LED 53 of the color display 49 is delayed. The flashing is changed from the flashing of the cycle to the flashing of the fast cycle (1 second on / 0.5 second off) and starts flashing (S36). Further, the operation lamp 46 is switched from the lighting state to the fast flashing cycle (0.2 second on / 0.2 seconds). (S37), and the user is informed of the fact that automatic fire extinguishing due to running out of fuel will be performed, and then the user stops driving the combustion fan 23, the electromagnetic pump 20, and the convection fan 5. A fire extinguishing operation is then performed (S38).

  Even after this fire extinguishing operation is performed, until the operation switch 38 is turned off, the red LED 53 and the operation lamp 46 of the color display 49 and the flashing display of the word “oiling” on the display unit 37 are continued. Even after the operation is finished, the red LED 53 of the color display 49 continues to blink rapidly, and even when the user is not near the device main body 1 at the time of fire extinguishing, the fact that the operation has stopped due to running out of fuel has been Can be clearly displayed, and it can appeal strongly that refueling is necessary, making it easy to use.

  Next, when the operation switch 38 is turned off (S39), an off operation confirmation sound "beep" is generated (S40), and the red LED 53, the operation lamp 46 and the display unit 37 of the color display 49 are turned off (S41). , S42, S43), when the user is not willing to refuel, it can be turned off by turning off the operation switch 38, so that the blinking display of the red LED 53 of the color display 49 feels visually noisy. Even when it is in the way, it can easily cope.

  As described above, the automatic fire extinguishing notice after a predetermined time has elapsed from the start of the operation is performed by blinking the color indicator 49 in green (retracted color such as green, blue, etc.), and automatically when the remaining fuel amount is reduced. The notice of fire extinguishing is made by flashing the color display 49 in red (advanced colors such as red, yellow, etc.) to appeal to the eye and make it possible to call attention more actively. If this is done, the cause of the automatic fire extinguishing notice can be clearly understood, and the user can take an appropriate action by pressing the extension switch 39 or refueling.

  In addition, the operation lamp 46 is turned on (flashes) when the operation switch 38 is turned on and turned off when the operation switch 38 is turned off, and an operation lamp 46 is displayed to indicate that the vehicle is in operation. Since the color indicator 49 to be notified is provided separately and separately, the operation of the operation switch 38 can be confirmed by the operation of the operation lamp 46 provided in the vicinity of the operation switch 38 and also during combustion. Preliminary notice of the existence and automatic fire extinguishing can be easily confirmed on the color display 49 which is displayed largely on the operation unit 2, and the current operating state of the device can be displayed more and clearly. It is easy to use.

  Next, it is conceivable that the fire extinguisher timer means 34 automatically extinguishes fire for about 20 to 40 minutes from when the float switch 19 is turned on until the fire extinguishes. The operation at this time will be described.

  When the float switch 19 is turned on in S10, the buzzer 48 generates a beeping sound three times in succession (S29), turns off the green LED 54 of the color display 49 that has been lit up until then (S30), At the same time, the red LED 53 of the color display 49 starts blinking with a slow blinking cycle (2 seconds on / 1 second off) (S31), and the characters “fueling” on the display unit 37 blinks (1 second on / 0.5 (Second off) is started (S32), and the number of drive pulses of the electromagnetic pump 20 is started (S33).

  Next, it is determined whether or not the counted number of pulses is greater than or equal to a predetermined value, and here it is less than or equal to the predetermined value (No in S34), so check whether the time counted by the forgetting-off timer means 34 is 15 minutes before the extinguishing time (S44).

  When the count time of the forgetting-off timer means 34 is 15 minutes before the fire-extinguishing time (Yes in S44), the buzzer 48 emits a notification sound "P-P-P" (S45), and the color display 49 In the state where the red LED 53 continues to blink slowly without changing the display of “”, the character of “OFF” is blinked on the segment of the display unit 37 displaying the room temperature (S46), and the automatic by the forgetting to turn off timer means 34 Inform the user that fire extinguishing is near.

  Returning to S34 again, the number of pulses has not reached the predetermined value, so the process proceeds to S44, and since S44 is No, the process proceeds to S47. Similarly, it is determined whether the count time of the forgetting to extinguish timer means 34 is 10 minutes before the extinguishing time. To check. When the fire extinguishing time is 10 minutes before, the display of the color display 49 is not changed as in the case of 15 minutes ago, and the buzzer 48 emits a notification sound “Peep-Peep” while the red LED 53 continues to flash slowly. (S48) The user is informed that automatic fire extinguishing by the forgetting to extinguish timer means 34 is near. The same applies 3 minutes before the fire extinguishing time.

  When the count time of the forget-to-extinguish timer means 34 reaches the fire extinguishing time (S50), the buzzer 48 emits a notification sound "P, P, P" (S51) and turns on the red LED 53 and the operation lamp 46 of the color display 49. When the light is turned off (S52, S53), the "OFF" character display on the display unit 37 is changed from blinking to light (S54), and it is informed that automatic fire extinguishing is performed by the forgetting to turn off timer means 34, the combustion fan 23, electromagnetic pump 20. Stop driving the convection fan 5 and perform a fire extinguishing operation (S55).

  When the operation switch 38 is turned off after the fire extinguishing operation is performed (S56), a confirmation sound “pipi” is generated for the off operation (S57), and the “OFF” character display and the fuel supply character display on the display unit 37 are turned off. (S58, S59). Since the “OFF” character display and the refueling character display are thus continued until the operation switch 38 is turned off, it is confirmed that the operation of the device has been extinguished by the timer means 34 and that the remaining fuel amount has decreased. You can know after the fire is extinguished.

  When the number of pulses of the electromagnetic pump 20 exceeds a predetermined value after the notification sound is generated by the forget-to-extinguish timer means 34 and before the extinguishing time of the forget-to-extinguish timer means 34 (S44 to S50), In S34, the result becomes Yes, and the operations in S35 to S43 are performed. The color display 49 blinks in red with a fast blinking cycle so that it can be clearly seen from a remote position that the operation has stopped due to running out of fuel. To do.

  Further, before the float switch 19 is turned on in S10, the remaining fuel amount is reduced before the extinguishing time of the forgetting-off timer means 34 comes after the notification sound is emitted by the forgetting-off timer means 34 (S11 to S20). When the float switch 19 is turned on (Yes in S10), the process proceeds to S29, where the color indicator 49 blinks with a slow red blinking cycle and the fuel has run out (Yes in S34), or 3 hours have elapsed since the start of operation (in S50). Yes) whichever is earlier, fire extinguishing control is performed.

  Thus, even if the color display 49 starts blinking in green once, when the remaining fuel amount is low, the color display 49 is changed to red blinking display and the fire extinguishing notice by the forgetting-off timer means 34 is displayed. Since the fact that the remaining fuel amount has decreased is displayed on the color display unit 49 with priority, it can be surely known that the remaining fuel amount has decreased.

  In addition, when the fuel is extinguished by the fuel extinguishing means 36, if the fuel is not refilled, it will disappear immediately even if the operation is started again. When the fire is extinguished by the forgotten extinguishment timer means 34, it is possible to make a quick flashing in the color red and quickly notify that the fire has been extinguished. The color display 49 is turned off because the operation can be started again and the operation can be continued without requiring another return operation.

  Next, when the timer switch 44 is turned on and the good morning timer means 35 is set, the difference from the automatic fire extinguishing by the forgetting-off timer means 35 will be described. From S1 to S9 in FIG. First, when the timer switch 44 is turned on (S60), an on operation confirmation sound “beep” is emitted from the buzzer 48 (S61), and the timer lamp 47 provided in the timer switch 44 is turned on. (S62).

  When the timer time is reached (S63), the operation lamp 46 starts blinking at a slow blinking cycle (on for 0.5 seconds / off for 0.5 seconds) (S64), energization of the vaporizing heater 26 is started, and the vaporizer 25 is started. Preheating is started (S65), and when the preheating is completed by detecting the temperature at which the vaporization temperature sensor 27 can be ignited (S66), the green LED 54 of the color display 49 is turned on (S67), and the operation lamp 46 starts blinking. The lighting operation is changed (S68), and the combustion fan 23, the electromagnetic pump 20, the igniter 30, and the convection fan 5 are driven to perform an ignition operation (S69).

  Then, the counting of a one-hour timer (referred to as “forgetting to turn off timer” for convenience) is started (S70). Thereafter, except for the count time of the forgetting to turn off timer being 1 hour, it is the same as after S10 in FIG.

  The good morning timer means 35 is released when the timer switch 44 is turned off, and is not released when the operation switch 38 is turned off. When the timer time of the next day comes, the operation from step S63 is repeated. It is.

  Further, the various operation switches provided in the operation unit 2 for performing the above-described various operations are arranged such that the display unit 37 is provided at the center, and the operation is a switch related to direct combustion that is normally used on the right side. By combining the switch 38, the extension switch 39, the up switch 40, and the down switch 41, the right-handed person who occupies the majority can easily operate the switch that is important and has a large number of operations while looking at the display unit 37, and the operation is easy. The display switch 42, the 5 second ignition switch 43, the timer switch 44, and the child lock switch 45, which are auxiliary function switches, are arranged on the left side. It can be used reliably without any accidental operation.

  The operation switch 38 and the extension switch 39 are arranged up and down with the operation switch 38 up, the up switch 40 and the down switch 41 are arranged up and down with the up switch 40 up, and the display changeover switches 42 and 5 are arranged. The second ignition switch 43 is arranged up and down with the display changeover switch 42 up, and the timer switch 44 and the child lock switch 45 are arranged up and down with the timer switch 44 up, so that the entire operation unit 2 is compact. Although the entire device is compact, it is most suitable for the operation part, and the operation part 2 which does not take up space is realized. Moreover, like the operation switch 38 and the extension switch 39, the up switch 40 and the down switch 41, etc. The related switches are arranged up and down, and the operation switch 38 of the main switch is up. Ri, since the operation of the up switch 40 to increase is above, very understandable easy and easy to operate, which further worry of malfunction is eliminated, in which easily manipulated can also blind people's eyes.
