It was something to do. Note that 11 is an inspection hole provided in the ceiling surface 10.

Problems to be Solved by the Invention In such a conventional configuration, conditioned air is supplied indoors and ventilation is also performed by the intake fan 4 and exhaust fan 5, but dirty air enters the room from outside. The freshness of the indoor air is not improved due to the inflow of air or the circulation of dirty indoor air, and the indoor air is used as it is even though the air is relatively polluted, especially in homes or offices where there are smokers. The issue was that ventilation was not effective in some areas.

The present invention has been made to solve these problems, and aims to provide a ventilation air conditioning unit that is capable of sufficient ventilation, sufficient air conditioning, and purifies the air.

Means for solving the problem (1) A partition plate that divides the main body into a front side and a rear side, and this partition plate has an air supply communication port that corresponds to the air supply fan and communicates with the rear side, and a heat exchanger. It is equipped with an air conditioning communication port that communicates with the rear side through the container and communicates with the rear L-shaped partition plate, and an outside air communication port that communicates with the air filter at the bottom, and an outside air intake port and a return intake. a supply air path in which air flowing in from the opening joins together on the rear surface side, passes through the air filter from the outside air communication port, passes through the air conditioning blower, passes through the heat exchanger, and reaches the indoor air outlet from the air conditioning communication port; The structure includes an exhaust air path that extends from an indoor suction port communicating with the indoor side to an outdoor exhaust port by an exhaust fan.

(2) In addition, when the top surface of the main body is provided with a return inlet for taking in lucky air and an outside air inlet that communicates with the outside air, and a return damper is provided in the return inlet and the return inlet is closed, Outside air is taken in only from the outside air suction port, and is removed from the air supply through the air supply port provided on the partition plate, passes through an air filter, is passed through a heat exchanger by an air conditioning blower, and is blown into the room from the air conditioning port. The structure includes an air supply path leading to the outlet.

Effect With this configuration, in the first invention, the air that flows in from the return suction port flows to the outside air communication port by the air conditioning blower, while the air that flows in from the outside air suction port flows through the air intake fan.
It passes through the supply air communication port and joins with the air that has flowed in from the return suction port, and this combined air is cleaned of dust by an air filter, passes through an air conditioning blower, passes through a heat exchanger, and passes through the L partition plate from the air conditioning communication port. Fresh air is supplied indoors by the air supply air path that passes through the air outlet and reaches the indoor air outlet.

Further, the second invention provides a return damper at the return suction port and closes the return suction port with the damper, so that a large amount of outside air is taken in from the outside air suction port and flows from the supply air communication port to the outside air communication port, Dust in the outside air is removed by an air filter, and a large amount of outside air is brought into the room through an air supply path that passes through the heat exchanger from the air conditioning blower and from the air conditioning communication port to the indoor air outlet.

EXAMPLE Hereinafter, an example according to the present invention will be described with reference to FIGS. 1 to 5. In the first invention, the main body 41 is installed in a meter space of an apartment complex or the like,
A partition plate 44 is provided that partitions the front side 42 and the rear side 43, and the partition plate 44 has an outside air intake port 46 provided on the top surface 45 and communicating with the attic or outdoors, and an outside air intake port 46 that connects the air returned from each room. an outside air communication port 48 through which air flows in from the return suction port 47, an air conditioning communication port 50 through which heated or cooled air passes through the heat exchanger 49, and a discharge port of the supply air fan 54. An air supply communication port 44a communicating with the rear surface side 43 is provided correspondingly.

On the other hand, in the lower part of the front side 42, there is an air filter 51 for coarse dust or high performance, and above it there is an air conditioning blower 52 for air conditioning, and the heat exchanger that exchanges heat with this air conditioning blower 52. A ventilation blower 55 is provided above 49 and includes an exhaust fan 53 for exhausting indoor air and an air supply fan 54 for taking in outside air.

Further, the top surface 45 has a front side 4 as shown in FIG.
2, an indoor suction port 56 that communicates with the indoor side and an outdoor exhaust port 5 that exhausts the air to the outdoors via the exhaust fan 53;
7, and an indoor air outlet 58 that passes through the heat exchanger 49 and heads toward the indoor side via an air conditioning communication port 50. Further, on the rear side 43, a rectangular partition plate 59 (
(shown by broken lines in FIG. 2) is provided.

In this way, in the main body 41 of the ventilation air conditioner according to the present embodiment, air flowing in from the outside air suction port 46 and the return suction port 47 is induced by the air supply fan 54 and the air conditioning blower 52, and the air is drawn from the air supply communication port 44a to the rear side 43 Dotted line arrow A flowing to
The dotted line arrow C flowing from the return suction port 47 provided on the rear side 43 of the top surface 45 merges and flows downward, passing through the outside air communication port 48, removing dust with the air filter 51, and passing through the air conditioning blower 52 for heat exchange. Indoor air is drawn by the exhaust fan 53 from the air conditioning communication port 50 through the L-shaped partition plate 59 to the indoor air outlet 58, and from the indoor air intake port 56. It also includes an exhaust air path 61 as shown by the arrow leading to an outdoor exhaust port 57 that communicates with the ceiling or the outdoors.

In the above configuration, since the indoor air is somewhat contaminated due to the living environment, the air flowing in from the outside air suction port 46 flows from the air supply communication port 44a to the rear side 43, and the air flowing in from the return suction port 47. It merges and flows downward to the rear side 43 outside the L-shaped partition plate 59, and the outside air communication 04
8 and then passes through an air filter 51. At this time, the dust in the dirty air in the room is removed, and fresh air is sent into the room from the indoor air outlet 58 via the air supply path 60.

On the other hand, a part of the indoor air is exhausted, which is sucked in through the indoor suction port 56 and exhausted through the outdoor exhaust port 57 by the exhaust fan 53 through the exhaust air path 61 shown by the arrow, thereby keeping the indoor air always clean. That's what I do.

As a result, the air flowing in from the return suction port 47 and the air flowing in from the outside air suction 046 are filtered through the air filter 51.
This ensures that dust is removed.

On the other hand, the second invention will be explained based on FIGS. 5 and 6. That is, in this embodiment, a return damper 62 is provided at the return suction port 47 provided on the rear side 43, and this return damper 62 communicates the air returned from the room.
It opens and closes in such a way as to switch between stopping and stopping.

In other words, when the return damper 62 is closed at the return air intake port 47 for return air from the room, the amount of air flowing in from the outside air intake port 46 increases, and a large amount of outside air is taken in, increasing the freshness of the indoor air. . Therefore, a large amount of outside air is supplied to the air supply fan 5 from the outside air suction port 46.
4, and passes through the ventilation path on the rear side 43 from the supply air communication port 44a as shown by the dotted arrow A, and the outside air communication port 4
8 and then an air filter 51 to remove dust. Here, the outside air may be dirty, so the air filter 51
This has the effect of removing dust. The air that has passed through the air filter 51 passes through the air conditioning blower 52 and is heated or cooled by the heat exchanger 49, and then passes through the air conditioning communication port 50, the L partition plate 59, and the indoor air outlet 58 as shown by the large arrow B.
A large amount of fresh air is supplied into the room through the air supply path 6o leading to the room.

Effects of the Invention As is clear from the description of the embodiments described above, in the present invention, the air flowing from the outside air intake port to the rear side through the air supply communication port and the air flowing in from the return intake port are combined by the exhaust fan, A supply air path that passes through the side, passes through an air filter from an outside air communication port, is dust removed there, passes through a heat exchanger by an air conditioning blower, passes through an air conditioning communication port, passes through an L-shaped partition plate, and reaches an indoor air outlet; Since the structure is equipped with an exhaust air path that runs from the indoor suction port to the outdoor exhaust port using an exhaust fan, the air returned from the return suction port and the air flowing in from the outside air suction port pass through the outside air communication port. pass through the filter,
Here, the dirty return air and outside air are purified and have the effect that fresh air can be supplied indoors through the supply air path.

In addition, by providing a return damper at the return suction port, if the return suction port is closed, the amount of outside air taken in from the outside air suction port can be increased, and this outside air is also removed by the air filter, removing dust from the outside air. This has the effect of purifying dust and the like from the surrounding residential environment and supplying it indoors.
