Is represented. After the start of operation, when the warm water temperature detected by the warm water temperature detecting means 8 does not reach the first set value (for example, 50 ° C.), the wind direction plate 13 is held forward while the blower 7 is stopped (step ST1-
Step ST3). When the hot water temperature becomes equal to or higher than the first set value (50 ° C.) determined in step ST1, step ST
In step 4, it is determined whether the blower 7 is stopped, and if it is stopped, in step ST5, it is repeatedly determined until the hot water temperature becomes equal to or higher than a second set value (for example, 58 ° C.) higher than the first set value. Then, when the value exceeds the second set value, the low-speed operation of the blower 7 is started (step ST6).

風機７および風向板１３の制御が開始される。When it is determined in step ST4 that the blower 7 is in operation, in step ST7, a fourth hotter temperature higher than a set value (for example, 61 ° C.) of a third hot water temperature, which will be described later, is set.
The hot water temperature is determined with the set value (for example, 65 ° C.), and when it has not risen to the fourth set value, the hot water temperature is determined with the third set value in step ST8. Then, when the warm water temperature is between the third set value higher than the second set value and the fourth set value higher than the third set value, the blower 7 is operated at a low speed and the wind direction is changed. Board 1
3 is held upward (step ST9 to step ST
10). This is because the warm air up to this stage is not warm enough. When the warm water temperature exceeds the fourth set value of 65 ° C. and if the forced operation is set in step ST11, the process proceeds to step ST12 and the wind direction plate 13 is directed forward as shown in FIG. The vicinity of the surface is warmed with warm air, and when forced operation is not set in step ST11, control of the blower 7 and the wind direction plate 13 as shown in FIG. 6 is started.

At T13, room temperature RT ≧ set temperature Ts−0.4 ° C.
If the condition is not satisfied, the blower 7 is set to high speed operation in step ST14, and the wind direction plate 13 is held forward in step ST15. When the condition of the room temperature RT ≧ the set temperature Ts−0.4 ° C. is satisfied in step ST13, the blower 7 is set to the medium speed operation in step ST16. At that time, the wind direction plate 13 is in a forward facing state (step ST17). When the room temperature RT reaches a temperature one step higher than the set temperature Ts (for example, + 1.2 ° C.) as shown in step ST18, the blower 7 is changed from the medium speed operation to the low speed operation in order to prevent the temperature near the floor from further increasing. At the same time as switching to operation, the wind direction plate 13 is turned upward and held (step ST19, step ST2).

きる。If the room temperature RT reaches a temperature that is two steps higher than the set temperature Ts (for example, + 1.6 ° C.) as shown in step ST21, the blower 7 is used to lower the temperature near the floor surface to near the set temperature. Is switched from low speed operation to very low speed operation (step ST22). If the room temperature RT still rises and reaches a temperature three steps higher than the set temperature Ts (for example, + 2.8 ° C) as shown in step ST23, the operation of the blower 7 is stopped in step ST24,
In step ST25, the direction of the wind direction plate 13 is returned to the forward horizontal state. In this way, it is possible to suppress an excessive temperature rise near the floor surface and to balance the temperature of the entire room. Note that step ST4 in FIG. 5 does not necessarily have to be provided at this position (step), and may be provided at all stages of step ST1. Further, the wind direction plate 13 (wind direction adjusting means 12) of the present embodiment can adjust only two directions of forward and upward, but further has a downward function,
If the wind direction plate 13 is held in a downward state when the operation is stopped for a long period of time, it is possible to prevent dust and the like from entering.
