Abstract

PURPOSE:To obtain a uniform temperature distribution, by arranging communication current passages between discharge current passages so that even if the air conditioner is installed in a room in a deviated manner, the air can be caused to convect. CONSTITUTION:The air in a room is sucked by rotation of a blower (c) via a suction port (d) and an orifice (m) into the blower (c), then is discharged to outlets i2, i3 of an air guider section i7, is blown to heat exchange sections e1, e2, and is blown out into a room from outlets g1, g2 via current paths f1, f2. When a wind direction adjusting plate h1 is adjusted to a little bit closed, and a wind direction adjusting plate h2 is adjusted to a little bit opened, since the resistance at the outlets g1 increases more than the resistance at the outlet g2, part of air that has passed the outlet i2 of a drain pan (i) flows via communication current passages i4, i5 to leave from the outlet g2. Therefore, a little amount of air current is discharged from the outlet g1, while a large amount of air current is discharged from the outlet g2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner installed buried in the ceiling of an air-conditioned room.

Conventional Structure and Problems Conventionally, this type of ceiling-embedded air conditioner (hereinafter referred to as an air conditioner) is generally shown in FIGS. 3 to 5. That is, in this figure, a indicates the air conditioner body buried in the ceiling, and b indicates a decorative panel exposed outside the ceiling and installed on the main body. A blower C is provided approximately at the center inside the air conditioner main body a, and the indoor air passes through the inlet d of the decorative panel b and exits the blower C, and is then transferred to the left and right heat exchangers e1. e
2 through the air path f1. Through f2 to the discharge ports q on both sides of the suction port 6
It is discharged indoors from 1+92. And this discharge port q
1. q2 has a louver h1 for adjusting the wind direction. h2 is provided.In such an air conditioner, there is no problem if it is installed almost in the center of the air-conditioned room, but if it is installed unevenly, the discharge air υ discharged from one outlet will be The discharged air collides with the wall of the air-conditioned room and is discharged from the other outlet, but does not reach close to the other wall.Therefore, the convection of the air is biased and a uniform temperature distribution cannot be obtained.

Purpose of the Invention Therefore, in order to eliminate the above-mentioned drawbacks, the present invention aims to achieve uniform temperature distribution by convecting air throughout the room even if air conditioners are installed unevenly in the air-conditioned room. be.

Structure of the Invention In order to achieve this object, the present invention provides a communication air passage between the discharge air passages, and allows the discharge air of one side to be discharged through the communication air passage to the outlet of the other side by operating a wind direction adjustment plate. Therefore, one side can send a small amount of discharge air, and the other side can send a large amount of discharge air. In other words, the purpose is to make it possible to vary the air volume.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In the figure, a ceiling-embedded air conditioner main body is shown, with a rectangular box a having an opening on the bottom surface inserted into an opening drilled in the ceiling 1 and located inside the ceiling j, and a box exposed from the ceiling j. A pair of long discharge ports q1 are provided on the outer periphery of this suction port d, which consists of a rectangular decorative panel b that is attached and fixed to the body a.
It forms q2. On the other hand, inside the box body a, there is provided a single-suction type blower C facing the suction port d, and a motor n for driving this blower C, and a pair of heat exchangers facing oppositely to each other on two sides of the outer periphery of the blower. Vessel e1. e2 is placed.

These heat exchangers e 1 and e 2 have wind direction adjustment plates h1 and h
2 through a ventilation passage f11f2 with a long outlet q1.
It communicates with q2. Heat exchanger e using blower C 1.
Ventilation to e2 is guided by an air guide portion 17 of the drain pan i integrally formed of a heat insulating material such as styrofoam. That is, drain pan i is connected to heat exchanger e1.
Drain hole part 11 that receives drain water of e2
A blowing opening 11.12 is formed surrounding the outer periphery of the blower C and facing the heat exchanger 61+82, and the ventilation passage f1
．． A communication air passage 14 for communicating with f2.

It is equipped with an i5.

A suction opening i6 is bored in the center of the drain pan i, located on the suction side of the blower C.
is equipped with an orifice m. In the above configuration, a blower C is operated by a motor n.
Due to the rotation of , indoor air is sucked into the blower C through the suction port d and the orifice m, and is discharged to the blow-off opening 12.13 of the air guide part 17, and is then transferred to the heat exchange part e1. e2, and the ventilation passage f1. f2 to discharge port q1. q2 is blown into the room.

In this case, the ventilation path f1. f2, discharge port Cr1. In the case where the resistance of CI2 is uniform, the amount of air blown from the discharge ports 91+q2 is equal, and the amount of air blown from the discharge ports q1.
The air pressure in the vicinity of q2 is also equal, and as long as this is the case, no air flows through the connecting air passages 14,15.

However, when the wind direction adjustment plate h1 is adjusted to almost close and the other wind direction adjustment plate h2 is adjusted to almost open, the resistance of the outlet q1 increases significantly than the resistance of the outlet q2, so that the opening 12 of the drain pan i A part of the air that has passed through flows through the connecting air passage '4115 and is discharged from the discharge port q2. Therefore, a small amount of air is ejected from the outlet q1, and a large amount of air is ejected from the outlet q2.

Effects of the Invention As is clear from the above explanation, according to the present invention, a heat exchanger is arranged symmetrically to the blower, and a ventilation passage communicating with the discharge port of the decorative panel is provided on the outside of the heat exchanger. Since the ventilation channels have communication channels that communicate with each other, and are equipped with a wind direction adjustment plate that guides the flow of air in the communication channels, a large amount of air is sent to one outlet, and a small amount is sent to the other outlet. The so-called variable air volume is possible.

As a result, even if the air conditioner is installed unevenly in the air-conditioned room, by adjusting the wind direction control plate, the air can be circulated to every corner of the room, and comfortable air conditioning can be performed.
