Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a ceiling-embedded air conditioner that is equipped with air outlets on four sides and is capable of airing from four directions.

(Prior art) As shown in Fig. 7, conventionally, a suction port F was installed in the center of the lower part of the casing that was embedded in the ceiling.
In addition, a ceiling-embedded air conditioner that enables airflow from four directions by installing a rectangular air outlet grille E with air outlets A to D on four sides is disclosed in, for example, Japanese Patent Laid-Open No. 110821/1982. As stated, it is already known.

In the conventionally known four-way air conditioner, a wind direction changing plate is provided at each of the air outlets A to D, so that the direction of the conditioned air blown from the air outlets A to D can be changed. However, the opening area of each outlet A to D is set to an area corresponding to the fan capacity. That is, the opening area of each outlet A to D is set based on the four-way outlet standard in accordance with the fan capacity.

(Problem to be solved by the invention) By the way, the above-mentioned ceiling-mounted air conditioner with four-way outlet is usually installed in the middle of the indoor ceiling and used with four-way outlet specifications. However, if the shape of the chamber is vertically long or the installation location is not in an intermediate position, it is necessary to change to a two-way or three-way outlet. Therefore, in this case, the unnecessary air outlets are closed by the closing member, but the air outlets A to D
Since the opening area is set based on a four-way air outlet, if the air outlet is set to two or three directions, the wind speed will increase, creating a problem in which residents will feel a draft sensation.

In order to solve this problem of draft feeling, it is possible to set the opening area on the basis of two-way or three-way blowout, but in this case, when used with four-way blowout specifications, the wind speed will be lower and the reaching distance will be shorter. Become,
Another problem arises when heating the room, which prevents the feet from getting warm.

The purpose of this invention is to provide two
Even if you change to 2-way or 3-way airflow, the wind speed can be made almost uniform, solving the conventional problem of feeling like a draft and not getting your feet warm during heating, and optimizing the temperature distribution with either 2-way or 4-way airflow. The point is to make it so.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention aims to solve the above-mentioned problems by using two of the four air outlets 11 to 14 facing each other, as shown in FIG. Forming a plurality of closing bodies 15 to 18 that can close 14,
These closing bodies 15 to 18 are connected to four air outlets 11 to 1.
4, and the air outlet can be changed from two to four directions without changing the air outlet area.

(Function) The closing bodies 15 to 18 are connected to two air outlets 13,
14 and closes these two air outlets 13 to 14, resulting in a two-way air outlet, where one (for example, 13) of the two air outlets 13 and 14 described above is closed and the other (for example, 14) is opened. By attaching the closing bodies 17 and 18 that closed this outlet 14 to other outlets 11 and 12, or by closing all the closing bodies to one outlet 11, a three-way outlet is created. Furthermore, the closure body 17,
By attaching the closing bodies 17, 18 of the air outlet 13, which had been closed by the air outlet 18, to the air outlet 11, 12, a four-way air outlet is created.
The opening area does not change in any of the directions, from directional to four-directional, and the wind speed can always be kept almost constant.

(Embodiment) In the embodiment shown in FIG.
A U-shaped heat exchanger 3, fans 4, 5, and a control box 6 arranged inside the heat exchanger 3 are housed inside the heat exchanger.

The decorative panel 2 is mainly a molded product of semi-rigid foamed urethane resin, and has a weir 7 and a drain pan 8 on the upper surface, and a lower surface exposed to the indoor side with respect to the ceiling 30 is made of vinyl chloride, for example. A resin skin 9 is adhered.

This decorative panel 2 is provided with a suction port 10 at its center, and the four sides surrounding this suction port 10 are of the same width and have airflow ports 11 to 11 to which air direction adjustment plates (not shown) are attached. There are 14.

Among these air outlets 11 to 14, first and second air outlets 11 and 12 provided on the long side of the panel 2
are the third and fourth air outlets 13 and 1 provided on the short side.
4, the outlet openings 11 to 14 are stepped so that closing bodies 15 to 18 for adjusting the opening area can be removably attached to the outlets 11 to 14. .

The closing bodies 15 to 18 are mainly formed integrally through a thin-walled cutout 20 as shown in FIG. It is attached to the air outlet mainly by frictional engagement.

Further, the length of the closing bodies 15 to 18 is such that the third and fourth outlets 13 and 14 can be closed, that is, in this embodiment, the length is half the length (1/2) of the length of the outlets 13 and 14. ).

In FIGS. 1 and 4, each of the closing bodies 15 to 1
8 are installed on both sides in the length direction of the first and second air outlets 11 and 12 to provide a four-way air outlet, and by installing the closing bodies 15 to 18 to the first and second air outlets 11 and 12. The opening area of each outlet 11 to 14 is the same.

Therefore, the fans 4 and 5 are connected to the air outlet 1.
1 to 14, i.e., the closure body 15 to
The one that provides the desired wind speed (usually 4 m/sec) is selected in accordance with the opening area when the air conditioner 18 is attached.

Therefore, in the above configuration, the closure body 1
5 to 18 are the first and second air outlets 11 and 12.
When the fan 4,
5, the suction grille 19 is opened from the suction port 10 by the drive of the
The indoor space sucked in via the heat exchanger 3
After that, the air is blown into the room from the four outlets 11 to 14 at approximately uniform wind speed.

In order to change from this four-way air outlet to three-way air outlet, two of the closing bodies 15 to 18 attached to the first and second air outlets 11 and 12 are removed from the third air outlet 13. Or the fourth outlet 14 or the first
Alternatively, this can be done by attaching it to the second outlet 11 or 12 and closing one of these outlets.

What is shown in FIG. 5 is the closure body 17, 18.
is attached to the third air outlet 13 and this third air outlet 13
This is done by closing the

Also, to change from 3-way blowout to 2-way blowout,
As shown in FIG. 6, this is done by attaching the closing bodies 15 to 18 to the third and fourth outlets 13 and 14 and closing these outlets 13 and 14.

As described above, by selecting the closing bodies 15 to 18 as the four air outlets 11 to 14,
When changing in this way, the opening area remains unchanged, and therefore the wind speed of the air blown out from each outlet can be adjusted to the preset optimal wind speed (4 m / sec).

In addition, when the suction port 10 is provided in the center of the decorative panel 2 as described above, and the air outlets 11 to 14 are provided to surround this suction port 10, it is difficult to secure a suction passage for four-way air blowing. Closed body 1
5 to 18 close both sides of the first and second blow-off ports 11 and 12, so that a sufficient suction passage can be secured and it is also possible to prevent short circuits.

In the embodiment described above, the lengths of the first and second air outlets 11 and 12 and the third and fourth air outlets 13 and 14 are different, but the lengths are the same, for example, the lengths of each of the air outlets 11 to 14 are different. One-quarter length (1/4)
It is also possible to form eight closing bodies and change the airflow from two to four directions. In this case, one closing body will be left over for three-way blowing, but it can be saved as a spare. When the lengths of the air outlets 11 to 14 are the same, for example, the first and third air outlets 1
1 and 13 to provide two-way airflow, it is convenient when installed in a corner of a room, and also convenient when the decorative panel 2 is made into a square shape.

(Effects of the invention) As described above, the present invention forms a plurality of closing bodies 15 to 18 that can close the two opposing air outlets 13 and 14 among the four air outlets 11 to 14, and Closing bodies 15 to 18 are connected to four air outlets 11
By selectively attaching the closing bodies 15 to 14 to change the outlet from 2 to 4 directions without changing the area of the outlet opening, it is possible to simply select the outlet 11 to 14 to which the closing bodies 15 to 18 are attached. It is possible to change the airflow from 2 to 4 directions, and even if this change is made, the total opening area of the air outlets remains unchanged, so regardless of the number of air outlets that are opened, the optimum wind speed can be maintained at all times. This eliminates the problems of creating a drafty feeling or shortening the reach, and it is possible to always optimize the temperature distribution.
