  According to the feature of the present invention, when the utility is consumed by the operation of the temperature adjusting means in a state where the user has inserted a predetermined amount of money into the input unit, the amount of the consumed utility is detected as the consumption amount. The consumption amount is calculated based on the utility consumption amount and the utility unit price, and the remaining amount is calculated based on the money amount and consumption amount inserted into the input unit, and the remaining amount is displayed.

As described above, since the remaining amount is reduced by the operation of the temperature adjusting means (utilization of the utility), the user can feel the consumption amount of the utility strongly by visually observing the reduced remaining amount. This increases the user's awareness of energy saving.
While the remaining amount decreases with the operation of the temperature control means (consumption of utility), the money is stored in the storage part when the user inserts money into the input part. Fun occurs.

A feature of the present invention is that the air conditioner is configured as follows.

[5]
Next, a state in which coins are inserted into the insertion unit 36 in a stopped state of the hot air heater and a unit price mode for setting the unit price of the gas G will be described with reference to FIGS. 5 and 6.
When coins are inserted into the insertion unit 36 in the stopped state of the hot air heating device (step S1), the type and number of the inserted coins are detected by the coin detection unit 37. Based on the detection signal of the coin detection unit 37, the remaining amount calculation means 28 detects the amount of coins inserted (inserted amount) (step S 2), and the remaining amount stored in the storage unit 30 has the input amount. By adding (step S3), the new remaining amount is updated and stored in the storage unit 30 (step S4).

  As described above, when coins are inserted into the insertion unit 36, the display control means 26 displays the remaining amount stored in the storage unit 30 on the room temperature display unit 20 and the target temperature display unit 21, and the set time ( When a few seconds elapse, for example, the remaining amount display disappears (step S5).

  When the mode change switch 31 and the mode setting switch 32 described in the preceding item [4] are pressed to set the unit price mode while the hot air heater is stopped, the unit price mode lamp 35 blinks. A state is entered (step S21), and the unit price of the gas G set previously is displayed in a blinking state on the room temperature display unit 20 and the target temperature display unit 21.

  Thus, the unit price of the gas G can be changed to a desired unit price by pushing and operating the ascending side portion and the descending side portion of the temperature setting switch 19 (step S22). Is displayed in a blinking state on the room temperature display unit 20 and the target temperature display unit 21 (step S23).

  When the unit price of the desired gas G is displayed on the room temperature display unit 20 and the target temperature display unit 21 and the mode setting switch 32 is pressed (step S24), the unit price mode lamp 35 is turned on, and then the unit price mode. The lamp 35, the room temperature display unit 20, and the target temperature display unit 21 are turned off (step S25), and the unit price of the gas G is set (step S26).

[6]
Next, the first operation mode will be described with reference to FIG.
In the state where the first operation mode is set, when the operation / stop switch 17 is pushed to enter the operation state, the operation control means 24 operates the first and second on-off valves 11 and 12 to the open position, and the ignition is performed. The combustor 2 is ignited by the combustor 15, and the motor 6 is operated, so that the hot air heater is in operation.

  As a result, the flow control valve 10 is operated by the operation control means 24, and the combustor 2 is operated (controlled) with the maximum heating capacity. When the room temperature reaches the target temperature, the room temperature is maintained at the target temperature. As described above, the combustor 2 is operated (controlled) (step S35).

  In the first operation mode, the target temperature can be changed by pushing and operating the rising side portion and the falling side portion of the temperature setting switch 19 (step S31), and the changed target temperature is displayed in the target temperature display section. 21 (step S32). At the same time, the room temperature sensor 22 detects the room temperature (step S33), and the room temperature is displayed on the room temperature display unit 20 (step S34).

  In the first operation mode, when coins are inserted into the insertion unit 36 (step S36), the type and number of inserted coins are detected by the coin detection unit 37. Based on the detection signal of the coin detection unit 37, the remaining amount calculation means 28 detects the amount of inserted coins (injection amount) (step S 37), and the remaining amount stored in the storage unit 30 includes the input amount. Addition is performed (step S38), and the new remaining amount is updated and stored in the storage unit 30 (step S39).

  As described above, when coins are inserted into the insertion unit 36, the display control means 26 causes the room temperature display unit 20 and the target temperature display unit 21 to display the room temperature and the target temperature, and the remaining amount stored in the storage unit 30. Is displayed (step S40). Next, when a set time (for example, several seconds) elapses, the remaining amount display disappears in the room temperature display unit 20 and the target temperature display unit 21, and the room temperature and the target temperature are displayed (step S41).

  In the first operation mode, the remaining amount calculation means 28 detects the amount of inserted coins (injected amount), adds the inserted amount to the remaining amount stored in the storage unit 30, and the new remaining amount by the storage unit 30. The amount is updated and stored.

  In this case, in the first operation mode, the remaining amount calculation means 28 does not perform the calculation of the consumption amount described in [8], which will be described later, or the process of subtracting the consumption amount from the remaining amount, and continuously enters the operation state. be able to.

As described above, the state described in this item [6]
“First operation mode in which the temperature adjusting means (combustor 2) is operated under the condition that the use of the utility (gas G) is not limited to the usable amount while the remaining amount calculating means 28 is stopped”
It corresponds to.

[7]
Next, the operation state in the second operation mode will be described with reference to FIG.
In the state where the second operation mode is set, when the operation / stop switch 17 is pressed to enter the operation state, the operation control means 24 operates the first and second on-off valves 11 and 12 to the open position, and the ignition is performed. The combustor 2 is ignited by the combustor 15, and the motor 6 is operated, so that the hot air heater is in operation.

When in the operation state, the available amount calculation means 29 calculates the amount of the gas G corresponding to the remaining amount as the usable amount based on the remaining amount and the unit price stored in the storage unit 30 (step S51). .
Also in the second operation mode, as in the first operation mode, the flow control valve 10 is operated by the operation control means 24, and the combustor 2 is operated (controlled) at the maximum heating capacity, and the room temperature When the temperature reaches the target temperature, the combustor 2 is operated (controlled) so that the room temperature is maintained at the target temperature (step S56).

In the second operation mode, the target temperature can be changed by pressing and operating the ascending side portion and the descending side portion of the temperature setting switch 19 (step S52), and the changed target temperature is displayed in the target temperature display section. 21 (step S53). At the same time, the room temperature sensor 22 detects the room temperature (step S54), and the room temperature is displayed on the room temperature display unit 20 (step S55).
Along with the operation of the combustor 2, the consumption of the gas G is detected and integrated by the detection means 25 based on the time elapsed since the operation state was reached and the opening degree of the flow control valve 10 (step S 57). .

  In the second operation mode, when the mode changeover switch 31 is pushed and operated (step S58), the room temperature and the target temperature displayed on the room temperature display unit 20 and the target temperature display unit 21 are erased by the display control means 26, and the room temperature display unit is displayed. 20 and the target temperature display unit 21 display the remaining amount stored in the storage unit 30 (step S63). Next, when a set time (for example, several seconds) elapses, the remaining amount display disappears, and the room temperature and the target temperature are displayed on the room temperature display unit 20 and the target temperature display unit 21 (step S64).

  In the second operation mode, when coins are inserted into the insertion unit 36 (step S59), the type and number of inserted coins are detected by the coin detection unit 37. Based on the detection signal of the coin detection unit 37, the remaining amount calculating means 28 detects the amount of coins inserted (injected amount) (step S60), and the remaining amount stored in the storage unit 30 includes the input amount. By adding (step S61), the new remaining amount is updated and stored in the storage unit 30 (step S62).

As described above, when coins are inserted into the insertion unit 36, the display control means 26 causes the room temperature display unit 20 and the target temperature display unit 21 to display the room temperature and the target temperature, and the remaining amount stored in the storage unit 30. Is displayed (step S63). Next, when a set time (for example, several seconds) elapses, the remaining amount display disappears in the room temperature display unit 20 and the target temperature display unit 21, and the room temperature and the target temperature are displayed (step S64).
In this case, in the operation state in the second operation mode, the operation state in the second operation mode is maintained unless the operation / stop switch 17 is pushed to enter the stop state in the second operation mode.

[8]
Next, the stop state in the second operation mode will be described with reference to FIG. 9 (part 1).
In the operation state in the second operation mode described in [7] above, when the operation / stop switch 17 is pressed to enter the stop state, based on the consumption amount and unit price of the gas G detected by the detection means 25, The consumption amount calculation means 27 calculates the consumption amount of the gas G (step S71).

The consumption amount is subtracted from the remaining amount by the remaining amount calculation means 28 (step S72), and the new remaining amount is updated and stored in the storage unit 30 (step S73).
When the remaining amount is higher than the set amount (small amount) (the remaining amount is sufficiently left) (step S74), the room temperature display unit 20 and the target temperature display unit 21 are displayed by the display control unit 26 and the remaining amount calculation unit 28. The remaining amount stored in the storage unit 30 is displayed in a lighting state (step S75).

  When the remaining amount is lower than the set amount (small amount) (the state in which there is not much remaining amount) (step S74), the display control unit 26 and the remaining amount calculation unit 28 cause the room temperature display unit 20 and the target temperature display unit 21 to The remaining amount stored in the storage unit 30 is displayed in a blinking state, and a warning buzzer (not shown) is activated (step S76).

In step S71, when the consumption amount is subtracted from the remaining amount, if the consumption amount is higher than the remaining amount and the remaining amount is negative, the room temperature display unit 20 and the target temperature are displayed by the display control unit 26 and the remaining amount calculation unit 28. The remaining amount is displayed as a minus on the display unit 21 (for example, “-” is displayed before the remaining amount) (step S76).
After a set time (for example, several seconds) after steps S74 and S75, the remaining amount display disappears (warning buzzer stops) (step S77).

[9]
Next, the stop state in the second operation mode will be described based on FIG. 5 (part 2).
In step S51 of FIG. 8, the usable amount calculating means 29 calculates the usable amount of the gas G when the operation state in the second operation mode is entered. In this case, the usable amount and the remaining amount are synonymous parameters.

  When the second operation mode is maintained in the second operation mode (steps S6 and S7), if the usable amount remains (the usable amount is not zero) (step S8), Shifting to FIG. 8, the operation state in the second operation mode can be resumed.

  In step S71 in FIG. 9, when the consumption amount is deducted from the remaining amount, the consumption amount is higher than the remaining amount, and when the remaining amount is negative, the usable amount is used up (the consumable amount is reduced to zero). (Steps S8 and S9).

  Thereby, in the above-mentioned state, when it becomes the stop state in the second operation mode and the second operation mode is maintained (steps S6 and S7), the operation state is prohibited (stop state) (step S10). Even if the operation / stop switch 17 is pushed and operated in the prohibition (stop state) of this operation state (step S11), the remaining amount is displayed in a blinking state on the room temperature display unit 20 and the target temperature display unit 21, and the set time Since the remaining amount display disappears after the elapse of time (step S12), the prohibition of the operation state (stop state) is maintained.

  In this case, when a coin is inserted into the insertion unit 36 in the prohibition (stop state) of the operation state (step S1), steps S2 to S5 (see [5] in the previous section) are performed, and when the remaining amount exceeds zero. (Step S9), the process proceeds to FIG. 8, and the operation state in the second operation mode can be resumed.

As described above, the state described in [8] and [9] is as follows.
“The second operation mode in which the temperature adjusting means (combustor 2) is operated under the condition that the use of the utility (gas G) is limited to the usable amount while the remaining amount calculating means 28 is operated”.
“In the second operation mode, the utility of allowing the temperature control means (combustor 2) to continue operating and prohibiting the temperature control means (combustor 2) from being restarted even if the remaining amount is less than zero.
