Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed on a ceiling or the like in a room, corrects unevenness in the air volume blown from air outlets in four directions such as four directions, and constantly cools and warms air with a uniform air volume. The present invention relates to a cassette type multi-directional blow-out ceiling air conditioner which ensures reliable feeding and maintains a comfortable indoor environment.

[0002]

2. Description of the Related Art Usually, in the case of a ceiling-mounted type multi-directional air conditioner such as a four-way air conditioner, a heat exchange coil and a fan motor are installed in the air conditioner due to the structure of the airframe. Cooling / heating air at a predetermined temperature is supplied to the entire circumferential direction below several outlets opened to the lower panel through the branch chamber.

[0003]

However, since most of these conventional structures are constituted by the single heat exchange coil and the fan motor, for example, the air passage near the air blower is used. A large amount of air in the inside, while the amount of air flowing in the air passage that is far away from the air passage decreases, and the air outlets are opened at different distances in accordance with the distance of the air blow, etc. It is difficult to blow more even air at the same time, and even if the blower duct close to the blower is slightly moved or the passage diameter is adjusted as the above solution, these adjustments are technically very advanced. And the structure is complicated, and it is difficult to simultaneously blow out a uniform amount of air from a large number of outlets.

In order to solve the above problems, the present invention provides an airframe
Inside the lower air passage and one side of the lower air passage
An upper air passage connected to the upper air passage and the lower air passage;
Blower ducts connected under each side of the
And an air outlet that is communicated and connected below the
Heat is exchanged in the upper air passage, and the lower air passage and
A cassette that blows air from the outlet through the air duct
A multi-directional blow-out ceiling air conditioner, wherein:
One side of the lower air passage, which is connected to
Is the diameter larger than the communicating part between the lower ventilation passage and the lower ventilation passage?
Formed larger in diameter than the air duct below
And an air pocket.

[0005]

According to the present invention, the heat exchange coil 3 is driven by driving the fan motor 2 having the above structure.
The air which has been heat-exchanged to an appropriate temperature in the branch chamber A does not directly flow into each of the ventilation ducts a and b of the branch chamber A, but temporarily flows into the air pocket 9 formed in the lower ventilation passage B to form a vortex. By operation, each air duct a,
The air was almost equally diverted to b, c, and d, so that substantially uniform cooling and warming air could be simultaneously sent from a number of outlets 8, 8, 8, 8 into the room.

Embodiments of the present invention will be described below. 1 is the bottom
It is a box-shaped body that opens the entire surface. Inside of Airframe 1
, A lower air passage B and one side of the lower air passage B
An upper air passage 5 connected to the upper air passage 5 and a lower air passage B
Short air ducts a, b,
c, d, and an outlet communicating and connected below the air duct
8, 8, 8, 8.

The fan motor 2 and the heat
Replacement coil 3 and drain pan 4 are installed and air is blown to the top
The heat is exchanged in the passage 5, and the lower air passage B and the air duct
Blowing from outlets 8, 8, 8, 8 through a, b, c, d
I do.

The outlets 8, 8, 8, 8 are located below the lower panel 6.
Open in four directions on the bottom. The suction port 7 is provided on the lower panel 6
Of the upper air passage 5 through the suction passage e.
It is connected with the communication.

The upper air passage 5 is in communication with the upper air passage 5.
One side of the lower air passage B is connected to the upper air passage 5 and the lower air passage.
Blower that is larger in diameter than the communicating part with passage B and below this one side
The air pocket 9 is formed to have a diameter larger than that of the cut a.

[0010]

【The invention's effect】 Heat exchanged air is removed from the upper
When it flows into the pocket (one side of the lower ventilation passage),
Current and the wind speed decreases, and the airflow
Spread enough to the sides and equalize the air volume at each outlet.
Can be equalized. Moreover, the terminal reflection of the airflow in the air pocket
It can also be expected to have a silencing effect.
