Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a wall-mounted indoor unit of a separate air conditioner.

BACKGROUND ART Conventionally, this type of wall-mounted indoor unit has been constructed as shown in FIG.

That is, the main body 2 of the indoor unit has an inlet 3 on the upper front surface for sucking indoor air, and also has an outlet 4 on the lower side, and a heat exchanger 5 provided inside facing the inlet 3. A cross-flow fan 6 of a once-through type is provided opposite the air outlet 4. By operating the cross-flow fan 6, indoor air flows in through the suction port 3, and the cold or warm air that has been heat-exchanged with the heat exchanger 5 passes through the cross-flow fan 6 and is blown out from the blow-off port 4 into the room. It was meant to circulate air. Note that 1 in the figure indicates a wall.

Problems that the invention aims to solve In this conventional configuration, the indoor air is only circulated by sucking indoor air and blowing it out as cold or warm air. ventilation was not carried out,
This created a problem in that when people smoked or there was an odor in the room, it filled the room and had to be ventilated by opening the windows.

This invention solves these problems,
To provide a wall-mounted indoor unit which is equipped with a ventilation device so that outside air is constantly taken into the room.

Means for Solving the Problem In order to solve this problem, the present invention provides the main body of the indoor unit with an inlet, an outlet, and an exhaust opening for exhausting indoor air, and also uses a partition plate inside the main body. an exhaust chamber and an air conditioning room are formed, and the air conditioning chamber is provided with a heat exchanger for air conditioning and a fan for indoor air circulation, with a part of the fan facing the exhaust chamber side; An exhaust duct is connected to the exhaust chamber from the back of the main body, and an intake duct is provided which penetrates the partition plate from the back of the main body and faces the air conditioning room.

Effect With this configuration, the air sucked in from the suction port in the air conditioning room is turned into cold and hot air by the heat exchanger and blown into the room from the outlet to perform air conditioning, while indoor air flows into the exhaust room from the exhaust opening. While being exhausted to the outside through the exhaust duct, outside air flows in through the intake duct and is guided into the air conditioned room, passes through the heat exchanger, and is supplied into the room from the outlet.

Embodiment An embodiment of the present invention will be described based on FIGS. 1 to 3. In Figures 1 and 2,
10 is a main body 10 of a wall-mounted indoor unit hung on a wall 9
A suction port 11 is provided above the front side of this main body 10, and an air outlet 12 for blowing air into the room is provided below.
(Fig. 3) and exhaust opening 2 for exhausting indoor air.
3 is provided. Inside the main body 10, an air conditioning room and a ventilation room 15 are divided by a partition plate 16, and the air conditioning room 14 has an outdoor unit (FIG. (not shown) and a heat exchanger 17 connected by refrigerant piping.
A through-flow type fan 20 is provided, one of which is supported by the shaft of the motor 18 and the other by a bearing 19 at the end of the exhaust chamber 15, and which is provided through the partition plate 16. 20 are arranged in several blocks, only one of which is located within the exhaust chamber 15 as an exhaust fan 21. An exhaust duct 2 is provided below the exhaust chamber 15.
3 is connected to the main body 1, and this exhaust duct 23 is connected to the main body 1.
It is led out from the back plate 22 of No. 0 through the wall 9. Further, it passes through the partition plate 16 from the suction space 24 (FIG. 3) on the windward side of the heat exchanger 17 above the air conditioning chamber 14, passes through the upper part of the exhaust chamber 15, and penetrates the back plate 22. An L-shaped intake duct 25 is provided that penetrates the wall 9 and communicates with the outside.

In the above configuration, the circulation for performing air conditioning for cooling or heating is that indoor air flows in from the suction port 11 and becomes cold air through the heat exchanger 17 that acts as an evaporator during cooling, and the heat exchanger 17 acts as a condenser during heating. It becomes hot air through the air and is blown out from the outlet. On the other hand, the exhaust opening 23 provided at the lower front
More indoor air flows into the exhaust chamber 15, and the fan 2
The air is discharged to the outside from the intake port 23a of the exhaust duct 23 by the exhaust fan 21 rotating with the exhaust gas. Intake air flows into the outside air intake port 25a, where the outside air is sucked by the fan 20, flows in an L shape, is drawn into the suction space 24 through the discharge port 25b, merges with air from the intake port 11, and flows into the fan 20. 20
The air passes through the heat exchanger 17 and is blown out from the air outlet 12 into the room.

As a result, the air introduced from the outside always passes through the heat exchanger 17, so cooled air is supplied into the room during cooling, and heated air is supplied into the room during heating. There is no feeling of warm air when heating or a feeling of cold air when heating.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention has an air-conditioning chamber and an exhaust chamber divided into a main body, a series of fans spanning the exhaust chamber and the air-conditioning chamber, and a part of the front plate of the exhaust chamber. Since the air conditioner is provided with an exhaust opening, an exhaust duct that communicates with the exhaust opening, and an intake duct that communicates with the outside and communicates with the air-conditioned room, it is possible to perform air conditioning and ventilation at the same time. , even if smoke or odor from smoking occurs in the room, it will be ventilated immediately and will not fill the room.
There is no need to increase the air conditioning load in the room by opening a window and releasing a large amount of air, and ventilation can be achieved simply by extending the fan toward the exhaust room.
