Abstract

PURPOSE:To easily and effectively regulate the speed of discharge air with a wide margin according to the height of a ceiling by a method wherein by sliding a regulating member from the indoor side under a state that an air conditioner is mounted, the opening area of the opening part of a discharge member is regulated. CONSTITUTION:Since an opening part 14 is disposed to a discharge panel 11 positioned on the under surface of a box body, under a state that an air conditioner is mounted, the tip of a control rod is hooked from a position below the box body to a catch part 16, and each slide plate 15 is slid in a direction in which it is opened or closed. For example, when an installed ceiling is high and the opening area of an opening part 14 is increased by full opening the slide plate 15, a discharge air speed is decreased, and a draft feeling exerted on a person in a room and in a position right below an air conditioner is relieved. When a ceiling is high and the slide plate 15 is slid in an opening and a closing direction by a proper distance to reduce the opening area of the opening part 14, a discharge air speed is increased to a value being high enough to allow the flow of discharge air to a floor surface. The speed of discharge air can be easily and effectively regulated with a wide margin.

).

In the air conditioner shown in FIG. 8 configured as described above, when the blower (22) is driven by the rotation of the electric motor (23), the indoor air flows from the suction port (3 (1) to the air filter ( 29) into the box body (21),
Heat is exchanged in a heat exchanger (24). The air after heat exchange is then transferred to the air passage (3) between the box body (21) and the guide pipe (27).
2) and is blown into the room from the air outlet (31).

Next, a conventional example shown in FIG. 9 will be explained.

In the figure, (34) is an air outlet panel that is attached to the bottom surface of the air conditioner box (21,) shown in Figure 8 so as to be exposed from the ceiling (C), and the air inlet (34) is installed in the center of the air conditioner. 35
) is formed, and an annular opening (36) is formed around the suction port (35). (37) and (38) are a closing plate and a blowout plate each having a size that divides the opening (36) into four parts, and a blowout port (39) is formed in the blowout plate (38).

In the air conditioner configured as described in -1-, prior to the installation work of the air conditioner, the conditioned air should be blown out in consideration of the relationship between the installation position of the air conditioner and the position of the occupants. The direction is determined, and the blow-off plate (38) is attached to the blow-off panel (34) so that the blow-off port (39) is arranged in that direction.

Next, a conventional example shown in FIG. 10 will be explained.

In the figure, (4]) is a blowout panel, (42) is a suction port formed in the center of the blowout panel (41), and (43) is a suction port formed in the center of the blowout panel (41).
(44) is a plurality of shielding plates slidably attached to the opening (43); The portion not covered by each shielding plate (44) serves as an air outlet (45).

In the air conditioner configured as described above, by sliding each shielding plate (44) and forming the air outlet (45) at an appropriate position on the air outlet panel (41),
The blowing direction of the conditioned air is, for example, four directions shown in (A) in FIG. 10, two directions shown in (B), three directions shown in (C),
And, they can be changed in one direction as shown in (D).

[Problem to be solved by the invention] However, as in each of the above-mentioned conventional examples, the suction ports (3 (1)
), (35), and (42).
31), (39), and (45), the temperature distribution in the horizontal direction indoors is almost uniform, but the temperature distribution in the vertical direction tends to be uneven. Particularly during heating, if the ceiling (C) is high, the hot air will not reach the floor surface, which will reduce the heating effect. Therefore, in this type of air conditioner, when the ceiling is high, the blowing speed is set to be high so that the blown air reaches the floor, and when the ceiling is low, the blowing speed is set to be high so that the air does not feel like a draft to the occupants. It is necessary to set the blowing speed slowly.

However, although the conventional air conditioner shown in FIG. 8 is provided with an adjustment mechanism (28) that lowers the guide tube (27) by -L, the amount of adjustment is extremely small, so It was not possible to expect an adjustment effect that would make the occupants feel comfortable. Moreover, the adjustment mechanism (28) has the support frame (
26), the adjustment mechanism (28) cannot be operated from the outside during installation of the air conditioner, and the box (21) must be removed from the ceiling (C) each time adjustments are made. It was necessary to disassemble each part.

Furthermore, in the conventional air conditioner shown in FIG. 9, the blowout direction can be changed by changing the position of the blowout port (39), but the size of the blowout port (39) itself remains unchanged. It was not possible to adjust the blowing speed.

Furthermore, in the conventional air conditioner shown in Fig. 10,
Although a plurality of air outlets (45) can be formed in each part of the air outlet panel (41) so that their positions can be changed, the total opening area of each air outlet (45) is always constant. As with the previous one, it was not possible to adjust the blowing speed.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an air conditioner that can effectively adjust the blowing speed of conditioned air over a wide adjustment range and that can be easily adjusted from the indoor side while the air conditioner is still installed.

[Means for Solving the Problems] An air conditioner according to the present invention has a blower and a heat exchanger built into a box buried in the ceiling, and also has indoor air in a substantially central part of the bottom surface of the box. A suction port is provided inside the box body, and a blowout member having an opening for blowing out the air after heat exchange into the room is arranged around the outer circumference of the suction port. It is equipped with an adjustment member that adjusts the opening area of the opening.

[Function] In the present invention, when the air conditioner is installed, by sliding the adjusting member from the indoor side and adjusting the opening area of the opening of the blowing member, the speed of the blowing air can be adjusted according to the height of the ceiling. It can be easily and effectively adjusted with a wide adjustment range.

The air outlet wheel (11) is a square air outlet panel attached to the lower surface of the box body (1) with screws (12).

In FIG. 2, (13) is a window hole formed in the blow-off panel (11) so as to insert the lower end of the guide pipe (6);
14) are openings formed in a band shape on each of the four sides of the blow-off panel (11) so as to be located on the outer periphery of the suction port (8). (15) are a pair of slide plates that are slidably disposed on the upper surface of the blow-off panel (11) in correspondence with each opening (14), and adjust the opening area of the opening (14). A protruding hook portion (16) is provided on the lower surface of the plate (15).

Next, the operation of the air conditioner of the first embodiment configured as described above will be explained.

As shown by the arrow in Fig. 1, when the blower (2) is driven by the rotation of the electric motor (3), the indoor air is pumped through the suction port (8).
) is drawn into the box (1) through the air filter (7), and heat exchanged in the heat exchanger (4). The conditioned air after heat exchange passes through the air passage (1 (1)) of the blow-off wheel (9) and is blown into the room from each opening (]4) of the blow-off panel (11).

When adjusting the blowing speed of the conditioned air blown out from the opening (14), hook the tip of an operating rod (not shown) onto the hook (16) from below the box (1). , slide each slide plate (15) in the opening or closing direction. For example, if the ceiling (C) on which the air conditioner is installed is low and the blown air reaches the floor sufficiently, the slide plate (15) can be fully opened to open the air conditioner as shown on the left and right sides of Figure 2. If the opening area of the portion (14) is increased, the speed of the blown air will be reduced, and the draft feeling given to the occupants directly below the air conditioner will be alleviated.

In addition, if the ceiling (C) is high and the blown air does not reach the floor, install a slide plate (15
