Abstract

PURPOSE:To prevent short-circuit of discharging air to a suction port and improve room cooling and heating effect by providing discharging air guide plates at first air discharging port and second air-discharging port. CONSTITUTION:A suction and discharge grille 11 is provided with first suction port 18, first discharging port 19, second suction port 20 and second discharging port 21. A partitioning plate 13 is provided with first discharging air guide plate 13 is provided with first discharging air guide plate 22, slanted toward the first air discharging port 19, at one side thereof while the same plate 13 is provided with second discharging air guide plate 23, slanted toward the second air discharging port 21, at the other side thereof. When the air-conditioning machine is operated under above-described constitution, air, flowed into the machine from the first suction air port 18, is blown off to the left direction while the air, flowed into the machine from the second suction air port 20, is blown off to the right direction therefore, the air, discharged from respective air discharging ports, will never by sucked into respective air suction ports and the short-circuit of the air will never be caused.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a ceiling-embedded air conditioner 7-hole blow-out device.

Configuration of conventional example and its time 7. Point A: As shown in Figure 3, conventional ceiling-embedded air conditioners have a main body 1 that is embedded in the ceiling, and a part that is visible on the ceiling when viewed from below. Intake and exhaust grill 2
The main body 1 has an interior partitioned by a partition plate 3, and includes a plurality of heat exchangers and a plurality of blowers for the heat exchangers (
(none of which are shown), and the intake and exhaust grille 2 has a first intake port 4 corresponding to the plurality of blowers, a first exhaust port 5, a second intake port 6, and a second exhaust lower. It is set up. Then, indoor air is taken in through each intake port and exhausted into the room through each exhaust port. Even though they are partitioned by the partition plate 3 and each intake and exhaust are iA, they are adjacent to each other, so that, for example, the air exhausted from the first exhaust port 5 is transferred to the second intake port 6. In addition, the air exhausted from the second exhaust lower is drawn into the first intake port 4 to a certain extent, causing the heating capacity to decrease. It had

OBJECTS OF THE INVENTION The present invention is based on the above-mentioned drawbacks of the prior art, and aims to prevent the exhaust air from leaking at the intake port, thereby increasing the cooling effect.

Invention・7. In order to achieve the above object, the present invention provides a ceiling-embedded air conditioner with a partition plate installed in the main body of the ceiling-embedded air conditioner, and a plurality of heat exchangers arranged opposite to the plurality of heat exchangers. a plurality of feeders or ridges, an intake/exhaust grill connected to the main body and provided exposed on the ceiling surface, and a first intake/exhaust grill formed by a partition plate on the main body side. An intake port, a first exhaust port, and a second intake port.

An exhaust guide plate is provided at the second exhaust port, the first exhaust port, and the second exhaust port, and the exhaust guide plate is provided at a position facing each of the intake ports, and the exhaust guide plate is provided at a position facing each of the intake ports to avoid the intake ports.・Explanation of an embodiment in which exhaust air is discharged in the direction of the raised position An embodiment according to the present invention will be described based on FIGS. 1 and 2. In the figure, reference numeral 10 denotes a main body of the air conditioner that is embedded in the attic, and an intake/exhaust grill 11 that is exposed on the ceiling surface 12 is attached to the main body 10.

A partition plate 13 is provided in the center of the main body 10 to partition the interior, and a first air blower 14 is located in one of the empty chambers partitioned by the partition plate 13. 1 heat exchanger 15 is provided.

In the other empty room partitioned by the partition plate 13, a second blower 1 and 16 are located.
6 is provided with a second heat exchanger 1 facing each other, and thus the main body 1
0 is equipped with a plurality of blowers and a plurality of heat exchangers as main equipment. The intake/exhaust grill 11 has a first intake port 1
8, a first exhaust port 19, a second intake port 20, and a second exhaust port 21. A first exhaust port 19 is provided on one side of the partition plate 13 and is inclined toward the first exhaust port 19iI'III.
A first exhaust guide plate 22 is provided on the other side that extends so as to make it slightly narrower, and is inclined toward the second exhaust port 21 side.
A second exhaust guide plate 23 is provided that extends so as to slightly narrow the exhaust port 21, and this second exhaust guide plate 23 is provided at a position facing the first intake port 18. That is,
The first exhaust guide plate 22 is provided at an angle in a direction away from the second intake port 20, and the second exhaust guide plate 23 is provided at an angle in a direction away from the first intake port 18. There is.

In the above configuration, when this air conditioner is operated, the first
Air flowing in from the intake port 18 passes through the first heat exchanger 15 by the first feeder 14 and is exhausted into the room from the first exhaust port 19. At this time of exhaust, the first exhaust guide plate 22 is 1' inside the first exhaust port 19. - Provided at an angle and in a direction away from the second intake port 20,
Blows out to the left. On the other hand, the air flowing in through the second air intake port 20 passes through the second heat exchanger 17 by the second blower 16 and is exhausted into the room through the second exhaust port 21 . At the time of this exhaustion, the second exhaust guide plate 23 is provided at an angle within the second exhaust port 21, avoiding the first intake port 18: The air that is exhausted from each exhaust port is taken in from each intake port, and there is no short circuit, and smooth intake and exhaust are performed.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides a partition plate in the main body of a ceiling-embedded air conditioner to connect a plurality of blowers and heat exchangers, and an air intake/exhaust system connected to the main body. a grille, a first intake port, a first exhaust port, a second intake port, a second
an exhaust port, the first exhaust port, and the second exhaust port;
Since an exhaust guide plate and a second exhaust guide plate are provided to exhaust the air in a direction that avoids each intake port, a part of the exhausted air flows back to the intake port, unlike the conventional system. More air is taken in/no iodine circuit occurs, and the air zone between intake and exhaust becomes clearer, increasing the cooling and heating effect.

Therefore, it exhibits effects such as improving indoor temperature distribution.
