BACKGROUND ART Conventionally, as this type of air conditioner, one in which a blower outlet of an air blower opens into a ceiling surface has been provided. In such air conditioners, room temperature is used as a reference for switching between cooling operation and heating operation.
The temperature of the supply air sent into the room from the outlet is used, or the cooling operation and heating operation are switched depending on the season, regardless of the room temperature or the temperature of the supply air. Incidentally, a vane for adjusting the blowing direction is attached to the air outlet of the blower device, and by swinging the vane, the temperature distribution in the room is made almost uniform. Here, near the area directly below the outlet, the temperature changes in a relatively short time due to the supply air sent out from the outlet, but in areas far away from the outlet, it takes a comparatively long time for the temperature to change due to the supply air. It takes a long time. Therefore, the reciprocating movement of the vane is temporarily stopped at both end positions when the vane is reciprocated so as to change the blowing direction of the supplied air, so that the supplied air is distributed almost uniformly throughout the room. Hereinafter, such an operation will be referred to as an intermittent reciprocating operation.

Generally, when the room temperature is higher than the supply air temperature,
Since the supply air tends to fall towards the bottom of the room, it is desirable to vary the blowing direction of the supply air over a wide angular range; when the room temperature is lower than the supply air temperature, the supply air tends to rise upwards in the room. Therefore, it is desirable to change the blowing direction of the supplied air within a narrow angular range centered on the direct downward direction. However, among the above configurations, with configurations that only measure room temperature or supply air temperature, or switch between cooling operation and heating operation depending on the season, it is not possible to know the magnitude relationship between room temperature and supply air temperature. There is a problem in that it is not possible to determine in what angular range the air blowing direction should be changed. Furthermore, considering the daily changes in the indoor temperature of a building equipped with an air conditioner, for example in the summer, the temperature changes as shown in FIG. That is, in the morning, when not much time has passed since the air conditioner was started, the average room temperature (solid line) is higher than the supply air temperature (broken line), but as the air conditioner operates, the supply air temperature and room temperature gradually become closer to each other. On the other hand, indoors near the window on the west side, the room temperature is lower than the average room temperature in the morning and rises more than the average room temperature in the evening, as shown by the dashed line in FIG. Therefore, the supply air temperature can always be set low relative to the average room temperature, but near the window on the west side of the room, the supply air temperature may become lower or higher than the room temperature. In other words, originally,
It is desirable to set the blowing direction of the supplied air according to each location in the room, but if the season is used as a reference, there is a problem that the blowing direction of the supplied air cannot be determined. The present invention aims to solve the above-mentioned problems, and by setting the angular range for adjusting the blowing direction of the supply air from the outlet based on the difference between the room temperature and the supply air temperature, it can be adjusted depending on the season etc. The objective is to provide an air conditioner that maintains a substantially uniform room temperature regardless of the air conditioner.

In order to achieve the above object, the present invention includes a vane that adjusts the blowing direction of air at the outlet of the blower, and a vane that drives the vane back and forth so that the blowing direction changes within a predetermined angular range. A drive unit;
A supply air temperature sensor that detects the temperature of the supply air sent into the room from the outlet, a room temperature sensor that detects the indoor temperature, and an angular range in which the blow direction changes based on the temperature difference between the supply air temperature sensor and the room temperature sensor.

According to the above configuration, the angular range in which the blowing direction changes is changed based on the temperature difference between the room temperature and the supply air temperature, so when the room temperature is higher than the supply air temperature, the blowing direction is changed over a wide angular range. By changing the direction of air, it is possible to prevent the supply air from accumulating in the lower part of the room, and when the room temperature is lower than the temperature of the supply air, by changing the blowing direction within a narrow angle range,
This prevents the supply air from accumulating in the upper part of the room. As a result, regardless of the season,
This allows the indoor temperature distribution to be almost uniform at all times.

As shown in FIG. 2, a blower box 1 is provided which communicates with an air blower, and a blower outlet 2 provided in the blower box 1 opens to the ceiling surface. A vane 3 is disposed inside the air outlet box 1 facing the air outlet 2. The vane 3 is a plate body that is rotatable around an axis parallel to the opening surface of the air outlet 2 and whose inclination angle with respect to the opening surface of the air outlet 2 is variable. By changing the inclination angle of the vane 3, the blowing direction of the supplied air can be changed. Speech box 1
A supply air temperature sensor 4 for detecting the temperature of the supply air is disposed inside, and a room temperature sensor 5 for detecting the room temperature is disposed on the ceiling surface at a location away from the air outlet 2.
The outputs of the supply temperature sensor 4 and the room temperature sensor 5 are the first
As shown in the figure, it is input to the temperature difference detection section 6,
A temperature difference between the supply air temperature and the room temperature is detected. Based on this temperature difference, the determination control section 7 sets an angular range for swinging the vane 3, and controls the vane drive section 8, which includes a motor, to drive the vane 3. Here, as explained in the section of the prior art, the vane 3 performs an intermittent reciprocating operation, and the amount of supply air sent out in a direction different from the direction directly below is larger than the amount of air supply sent out directly below. It's meant to be. As shown in Fig. 3a and b, the vane 3 can change the blowing direction of the supply air in a wide angular range θ 1 and change the blowing direction of the supply air in a narrow angular range θ 2 .
It can be switched between two types of states: one that changes with . Switching between the two types of states described above is performed as follows. That is, as shown in Figure 4, (room temperature -
(supply air temperature) and set a threshold value based on the temperature difference. That is, the threshold values include a first threshold value t1 and a second threshold value t2 , which are set to 0°C and 1 to 3°C, respectively. When the room temperature is lower than the supply air temperature, the blowing direction is changed within a narrow angle range θ 2 , and when the room temperature rises and the difference with the air supply air temperature exceeds the second threshold t device 2 ,
This time, try to change the blowing direction over a wide angle range θ1 . When the room temperature falls and the difference from the supply air temperature falls below the first threshold value t 1 , the blowing direction is changed again within a narrow angle range θ 2 . in this way,
The vane driving unit 8 is controlled so that when (room temperature - supply air temperature) exceeds the first threshold t 1 , the angle range is wide θ 1 , and when it becomes smaller than the second threshold t 2 , the angle range is narrowed θ 2 . be. Further, since the threshold value is set in two stages differing by 1 to 3 degrees Celsius to provide hysteresis, variations in the supply air temperature sensor 4 and the room temperature sensor 5 can be absorbed.
