For example, as shown in FIG. 8, two wind direction plates 100, 10
By using 1 to blow the warm air 103 having a high wind speed thinly from the upper side of the slow warm air 102,
A product that suppresses the upward flow of the lower warm air 102 is commercialized.

が悪くなる場合もある。In the prior art based on the wind direction control system shown in FIG. 8, the temperature of the floor surface becomes high and the temperature is made uniform, and it is effective when the floor surface temperature rises. . However, since the warm air 103 having a high wind speed is sent to the feet, the user feels a considerable air flow,
This air flow lowers the sensible temperature. Further, in an air conditioner with variable capacity, the temperature of the warm air is as low as around 30 ° C., which may make the user feel chilly and may not be comfortable.

線である。In order to improve the temperature distribution in the room,
In the system that controls the wind direction plate as described above,
If you do not understand the situation in the room, there is a risk that the floor temperature will not rise and warm air will accumulate in a certain place. Therefore, in order to grasp the situation in the room, a method is conceivable in which the room temperature detector detects the room temperature and the floor surface temperature detector detects the floor surface temperature to control the position of the wind direction plate. However, looking at the accuracy of the radiation sensor generally used as the floor surface temperature detector, there is a variation of ± 5.0 ° C. or more even with a single unit. An example of a case where this is stored in the decorative cover of the indoor unit due to its design is shown in FIGS. 9 to 11. However, in the figure, 17 is a makeup cover, 18 is a radiation sensor, and 19 is an infrared ray.

と温度のバラツキの幅が広い。Looking at the accuracy according to the opening area of the decorative cover 17, in the case of FIG. 9 (the area of one opening is 2 ×
25 mm), the variation is ± 21.1 ° C., but as shown in FIG. 10, even if the opening area is increased (the area of one opening is 2 × 40 mm), ± 13.4 ° C.
And there is wide variation in temperature.

There are methods such as temperature correction with two radiation sensors, but these lead to cost increase.

する。In order to achieve the above object, the present invention detects a temperature rise value per unit time on a floor surface from a radiation sensor which is a floor surface temperature detector, and uses it as a detection signal. Accordingly, the discharge wind direction plate is controlled so that the air can be sent toward the center of the floor surface, or the air that is parallel to the ceiling surface and the air that is parallel and downward to the wall surface.

The variation in the accuracy of the rise value is small despite the large variation in the accuracy of the radiation sensor.

ップS6)。Therefore, in FIG. 4, the wind direction plate control means 9 first compares the room temperature detected by the room temperature detector 8 (FIG. 1) with a predetermined set temperature (step S).
1). Then, as a result of this comparison, when the room temperature is lower than the set temperature, it is determined that the room temperature has not reached the temperature desired by the user and the temperature is still rising, and the warm air is blown to the center of the floor. The wind direction plates 6a and 6b are brought into the state shown in FIG. 3 (a) (step S6). When the room temperature is equal to or higher than the set temperature, it is determined that the room temperature has reached the temperature desired by the user and has already risen, and the floor surface temperature detector 7 (FIG. 1) detects the floor surface temperature. Then (step S2), the floor surface temperature deviation value ΔTf per unit time is calculated as described above (step S3). Then, the floor surface temperature deviation value ΔTf and the floor surface temperature deviation threshold value Δ stored in the floor surface temperature information storage unit 12 (FIG. 2) in advance.
The size of Tset is compared and discriminated (step S4), and the floor surface temperature deviation value ΔTf per unit time is calculated as the floor surface temperature deviation threshold value ΔT.
When it is smaller than set, it is determined that the temperature gradient per unit time is small and the floor surface temperature is stable, that is, the floor surface temperature is saturated, and the wind direction plates 6a and 6b are set to the state shown in FIG. Warm air that flows parallel to the ceiling surface and warm air that flows downward and parallel to the wall surface are blown out from the air outlet 5 (FIG. 1) (step S5). Further, the floor surface temperature deviation ΔTf per unit time is the floor surface temperature deviation threshold ΔTset.
Room temperature has reached the desired temperature when
It is determined that the floor surface temperature is still rising (while rising), and the wind direction plates 6a and 6b are set to the state shown in FIG. 3 (a) so that warm air flows toward the center of the floor surface. (Step S6).

4 is sent toward the center of the floor surface, and the living space warms up quickly and efficiently. Also, in the steady state when the floor surface temperature is saturated, as shown in FIG. The warm air 15 flowing along the wall surface and the warm air 16 flowing downward along the wall surface are blown out so that the temperature of the living space is not lowered and the human body is not exposed to the warm air. Therefore, the rise of the floor surface temperature is fast, and in a steady state, a comfortable heating space that does not feel the wind is formed.

When the wind direction plate 6 is in the state shown in FIG. 3B, the warm air flowing parallel to the ceiling surface and the warm air flowing parallel to the wall surface and downward are generated at a predetermined ratio. However, here, in the above-described embodiment, when the wind direction plate 6 is stationary,
In the state shown in (b), and as shown in FIG. 6 (b), the air flow ratio of the warm air flow 15 along the ceiling surface to the warm air flow 16 along the lower part of the wall surface is 30:70. Then, the horizontal temperature distribution of 5 cm above the floor in the living space at this time is shown in FIG.
It becomes like (b). On the other hand, as in the conventional method, even in the steady state, as shown in FIG.
When 0% warm air is blown toward the center of the floor, the horizontal temperature distribution of 5 cm above the floor in the living space is shown in FIG.
It becomes like (a). Comparing these horizontal temperature distributions, as compared with the case of the conventional method shown in FIG.
In the case of the above-mentioned embodiment shown in (b), it can be seen that the high temperature zone spreads in the living space. Also, regarding the wind speed at the feet, for example, between 8 tatami mats, the height in the center of the room is 5 cm above the floor, and the conventional method is 0.6 m / sec.
In the above example, it was weak at 0.3 m / sec and 30 cm above the floor.
In the conventional method, it was 0.8 m / sec, but in the above-mentioned embodiment, it was as weak as 0.3 m / sec.

Even if the measurement accuracy of the floor temperature is low due to the variation in the detection accuracy of the floor temperature detector, the floor temperature can be calculated by using the difference between the detection results and the floor temperature deviation value per unit time. Therefore, the floor surface temperature deviation value can be obtained with high accuracy, and therefore the floor surface temperature situation can be accurately determined. This makes it possible to accurately set the indoor temperature environment.

特徴とする空気調和機。1. An air conditioner in which an indoor unit main body having a blower and a heat exchanger housed therein sucks indoor air from a suction port by the blower, warms the air with the heat exchanger, and blows the air out into the room, The temperature rise value on the floor surface per unit time is monitored by the floor temperature detector, and when the temperature rise value is equal to or higher than a preset threshold value, air is blown toward the center of the floor surface to raise the temperature. An air conditioner configured to blow out air in a direction parallel to a ceiling surface and air parallel to a wall surface and downward when the value is equal to or less than the threshold value.
