Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ceiling-embedded air conditioner.

Conventional technology In recent years, the number of packaged air conditioners installed on the ceiling has increased due to the emphasis on space saving and interior design, and there has also been an increase in the number of packaged air conditioners installed in the ceiling where the air intake and air outlets can be freely laid out using ducts. It's coming. In a ceiling-embedded air conditioner that can connect a plurality of ducts, the air volume of each duct should be equal in principle, and it is desirable that the air volume of each duct be adjustable.

An example of a conventional ceiling-embedded air conditioner will be described below with reference to the drawings.

FIG. 4 is a vertical cross-sectional view of a conventional ceiling-embedded air conditioner, and FIG. 5 is a cross-sectional view of the same, in which 1 is a main body embedded in the ceiling, 2 is an inlet provided on the bottom of the main body 1, 3 is a heat exchanger that cools or heats the air sucked in from the suction port 2; 4a and 4b are blowers disposed on the secondary air side of the heat exchanger 3; and 5 is a heat exchanger that cools or heats the air sucked in from the suction port 2; This is a drain pan that receives condensed water. Reference numerals 6a, 6b, and 6c are air outlets provided on the opposite side of the main body 1 from the inlet, and among the three air outlets 6a and 6c are located approximately in front of the blowers 4a and 4b, respectively; is located between the blowers 4a and 4b. 7 is air outlet 6
The duct 8 is connected to the duct connection port provided on the outside of each of the ducts a, 6b, and 6c. 9 is blower 4
This is a ventilation chamber formed in the space between a, 4b and the air outlets 6a, 6b, 6c.

In the ceiling-embedded air conditioner configured as described above, the air sucked in from the suction port 2 by the two blowers 4a and 4b, and blown out into the ventilation chamber 9 via the heat exchanger 3 is as follows: air outlets 6a, 6b,
From 6c, it exits to duct 8 via duct connection port 7.

Problems to be solved by the invention However, in the above configuration, the blower 4
The distance from the air outlets 6a, 6b, 6c from the air blowers 4a, 4b is small, and it is almost impossible to equalize the wind pressure in the receiving chamber 9. The problem was that the amount of air was large, and the amount of air from the outlet 6b located between the blowers 4a and 4b was small.

In view of the above-mentioned problems, the present invention has been developed so that even when the number of blowers and outlets is different, the air volume from each outlet is equal, and the ratio of the air volume from each outlet can be set arbitrarily. The present invention provides a built-in air conditioner.

Means for Solving the Problems In order to solve the above problems, the ceiling-embedded air conditioner of the present invention is movable using a fixed part to the main body as a fulcrum at an appropriate position in front of the blower in the ventilation room. It is equipped with an appropriate number of wind direction plates.

Function The present invention uses the above-mentioned configuration to guide an appropriate amount of air blown from the blower to the outlet with a small air volume, to equalize the air volume from each outlet, and to control the direction of the wind direction plate. In addition, the ratio of air volume from each outlet can be set arbitrarily.

Embodiment Hereinafter, a ceiling-embedded air conditioner according to an embodiment of the present invention will be described with reference to the drawings. Note that the same parts as in the conventional example will be explained using the same reference numerals.

FIG. 1 is a vertical cross-sectional view of a ceiling-embedded air conditioner according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the same.
1 is a main body embedded in the ceiling; 2 is an inlet provided on the bottom or one side of the main body 1; 3 is a heat exchanger that cools or heats the air sucked in from the inlet 2; 4a, 4b are A blower is disposed on the secondary air side of the heat exchanger 3, and 5 is a drain pan that receives water condensed in the heat exchanger 3 during cooling. Reference numerals 6a, 6b, and 6c are air outlets provided on the opposite side of the main body 1 from the inlet 2, and among the three air outlets 6a and 6c are air blowers 4a, 4, respectively.
b, and the air outlet 6b is located almost in front of the blower 4.
It is located between a and 4b. 7 is the air outlet 6a, 6
The duct 8 is connected to the duct connection port provided on the outside of each of b and 6c. 9 is a blower 4a, 4
The air receiving chambers 10a and 10b are formed in the spaces between the air blowing outlets 6a, 6b, and 6c. It is fixed to the main body 1 near both sides of. FIG. 3 is a perspective view of the wind direction plate 10a, in which an adjustment bolt 1 is vertically fixed to the lower part of the wind direction plate 10a, which can freely move around the hinge 11 as a fulcrum.
2 protrudes outside the main body 1 from an arc-shaped opening 13 on the bottom of the main body 1, the range of movement is limited by the opening 13, and the main body 1 is fixed from the outside with a locking nut 14. Reference numeral 15 denotes a seal rubber having an arc-shaped slit to prevent air from leaking from the opening 13.

In the ceiling-embedded air conditioner configured as described above, the wind blown from the blowers 4a and 4b is transmitted through the wind direction plate 10 along with the front air outlets 6a and 6c, respectively.
An appropriate amount of air is also guided to the air outlet 6b by the air outlets 6a, 10b, making it possible to equalize the air volume from each of the air outlets 6a, 6b, and 6c.
By changing the direction of a, 10b, the air outlet 6a, 6b,
The ratio of air volume from 6c can be set arbitrarily.

Effects of the invention As described above, the present invention is a ceiling-embedded air conditioner in which the blower is installed on the secondary air side of the heat exchanger, and the air is guided into the air receiving room to the outlet that is not located in front of the blower. By providing a movable wind direction plate, in addition to making it possible to equalize the air volume from a plurality of outlets, it is also possible to arbitrarily set the ratio of the air volume from each outlet by changing the direction of the wind direction plate.
