The microcomputer 35 sets the automatic operation mode by operating the room temperature setting unit 14, that is, pressing one of the up / down switches 14 and 14B once. That is, when any one of the switches 16A, 16B, and 16C for strong combustion, medium combustion, and weak combustion is pressed, a fixed combustion mode in which combustion is performed at a selected combustion amount is set.

In the above-described configuration, when the automatic operation mode is set and the room temperature setting unit 14 sets the set room temperature to 22 ° C., for example, as shown in FIG.
When the saving operation switch 13 is turned on (S2) after the operation switch 11 is turned on (S1), the electric heater 28 of the vaporizer 25 is energized, and the vaporizer 25 is heated by this energization, and the vaporizer 25 is turned on. When the burner temperature sensor 29 detects that the vaporizable temperature has been reached, the burner motor 26B of the burner blower 26 is driven to perform prepurge for a predetermined time, and the fuel pump 31 is operated.

Merges with the combustion exhaust gas flowing out of the heater and becomes hot air, which is blown out from the hot air outlet 2 to heat the room in which the heater is installed.

As shown in FIG. 6, the current room temperature T (room temperature) detected by the room temperature sensor 20 is set to the set room temperature T1 (for example, 22 ° C.) set by the room temperature setting section 14 by the above-described warm air heating as shown in FIG. , The combustion amount of the vaporizing burner 24 decreases. Then, as shown in FIG.
Determines whether the current room temperature T has reached the set room temperature T1 only (S3), and determines the time (t) at which the current room temperature T has reached the set room temperature T1.
From 1), it is determined whether or not a predetermined period of time (for example, about 3 to 8 minutes) has elapsed (S4), and at the time (t2) after the predetermined period has elapsed, the humidity sensor 19 40% of the current humidity (indoor humidity) detected
It is determined whether it is less than (S5).

Therefore, if the current humidity is less than 40%,
As shown in FIG. 5 and FIG.
However, the first room temperature T1 (for example, 22 ° C.) set by the room temperature setting section 14 is set to a first temperature Δt0 set in advance.
(For example, 0.5 ° C.) automatically (S6). Therefore, the set room temperature becomes T2 (for example, 21.5 ° C.).
Is subjected to combustion control (S7).

On the other hand, when the current humidity (room humidity) is 40% or more, the microcomputer 35 sets the current humidity (room humidity) to 40%.
It is determined whether the above is not more than 50% (S8). Here, when the current humidity is 40% or more and less than 50%, the set temperature changing unit 36 sets the set room temperature T1 (for example, 22 ° C.) set by the room temperature setting unit 14 to the second set room temperature in advance. The temperature is automatically lowered by the temperature Δt1 (for example, 1.5 ° C.) (S9). Therefore, the set room temperature becomes T3 (for example, 20.5 ° C.), and the vaporization burner 24 is subjected to combustion control with the set room temperature T3 as the target room temperature (S7).

Further, when the current humidity (room humidity) is 50% or more, the set temperature changing unit 36 sets the set room temperature T1 (for example, 22 ° C.) set by the room temperature setting unit 14 to a third set room temperature. The temperature is automatically lowered by the temperature Δt2 (for example, 2.5 ° C.) (S10). Therefore, the set room temperature is T4
(For example, 19.5 ° C.), and the vaporization burner 24 is subjected to combustion control with the set room temperature T4 as a target room temperature (S
7).

Next, the operation of displaying the approximate humidity in the humidity display section 17 will be described with reference to the flowchart of FIG. 7 and the explanatory diagram of FIG.

First, when the operation switch 11 is turned on, the humidity sensor 1 is turned on when the operation switch 11 is turned on.
9 detects the current humidity (indoor humidity), and the microcomputer 35
The humidity detected by the humidity sensor 19 is stored, and the humidity display instructing unit 37 calculates the current humidity detected by the humidity sensor 19 from the start of the operation of the heater as a rough humidity value (for example,
As “35”), “35” is lit on the humidity display unit 17 (for example, see FIG. 8A).

Then, as shown in FIG. 7, the microcomputer 35 determines whether or not a predetermined detection time (for example, about 3 to 8 minutes) has elapsed (S1).
1) When the predetermined detection time has elapsed, the humidity sensor 19 detects the current humidity (room humidity) again (S1).
2). Then, the microcomputer 35 determines whether or not the detected humidity is less than 40% (S13), and when the detected humidity is less than 40%, the humidity display instructing section 37 sets the humidity display section 17 to “3”.
The lighting display of "5" is continued (S14).

On the other hand, if the detected humidity is 40% or more, the microcomputer 35 determines whether the detected humidity is 40% or more and less than 50% (S15), and if the detected humidity is 40% or more and less than 50%. , The humidity display instruction section 37 is the humidity display section 1
7 is turned on (S16) (see FIG. 8B). When the detected humidity is 50% or more,
The humidity display instructing section 37 lights and displays “55” of the humidity display section 17 (S17) (see FIG. 8C).

Therefore, the amount of liquid fuel used can be reduced, and energy can be saved.

When the set room temperature (T1) set by the user in the room temperature setting unit 14 is a predetermined room temperature of about 20 ° C. or more, the set temperature changing unit 36 automatically changes the set room temperature. When the set temperature set by the user in the room temperature setting unit 14 is set lower than 20 ° C., the user feels warmth even during the heating operation. Can be eliminated.

As shown in FIG. 6, the set temperature changing section 36 sets the temperature of the room temperature sensor 20 to about 3 to 3 times after the detected temperature reaches the set room temperature (T1) set by the room temperature setting section 14. After the elapse of 8 minutes, the set room temperature can be changed, so that the set room temperature can be automatically lowered by the set temperature changing unit 36 after the wall surface of the room to be heated has risen in temperature, and the room temperature can be changed to the set room temperature. Despite reaching, the problem that the user does not feel warmth can be resolved.
