Description

The air conditioner attached a ventilation device

The present invention relates to an air conditioner that can more comfortably change the indoor air conditioning environment, and in particular, by connecting the cross flow fan and the centrifugal fan to one motor shaft at the same time to force the indoor air flow and to introduce the outside air into the room. The present invention relates to an air conditioner equipped with a ventilation device to enable ventilation by a simple structure.

Air conditioning is to control the temperature, humidity, cleanliness, and airflow of the residential area, and so far, air conditioning, which has been merely performing temperature control, is the majority.

However, in recent years, the thermal insulation and airtightness of buildings have been further developed to save energy, which makes it difficult to provide natural ventilation. As a result, the introduction of fresh outside air reduces the indoor air quality.

In order to reduce the deterioration of indoor air quality, an air conditioner that can purify indoor air by adding an air purifying function has appeared.

1 and 2 is an exploded perspective view and a side cross-sectional view showing the indoor unit of the wall-mounted air conditioner according to the prior art of the separate air conditioner to which the air purification function is added.

The indoor unit of the wall-mounted air conditioner according to the related art has a chassis 10 having an inlet port I and an outlet port O for flow of air, and is installed inside the chassis 10 to provide the inlet port I and the outlet port O. The cross flow fan 13 forcibly flowing the air to suck and discharge the air through the air) and the air flowed by the cross flow fan 13 in front of the cross flow fan 13 to exchange heat with the refrigerant. It comprises a heat exchanger (15) for cooling through.

Here, the chassis 10 has an upper inlet (I) is formed on the upper surface and the front, respectively, the upper chassis 11 is formed with a discharge port (O) on the lower surface, and the lower chassis coupled to the rear side of the upper chassis ( 12).

In addition, a flow guide 17 is formed in the lower chassis 12 to form a flow path of air flowing by the cross flow fan 13, and one side of the cross flow fan 13 drives the cross flow fan 13. The motor 19 and the control box 20 is mounted.

In addition, a suction grill 11a is mounted to the upper chassis 11 in front of the suction port I, a discharge grill 11b is mounted to the discharge port O side, and the lower chassis is mounted to the discharge grill 11b. The vanes 21 and the louvers 23 which adjust the discharge direction of the air moved along the flow path guide 17 of 12 are respectively provided.

In particular, an air filter 31 and a dust collecting device 35 are installed at the rear of the suction grille 11a on the suction port I side of the upper chassis 11 for the purpose of purifying indoor air.

The indoor unit of the wall-mounted air conditioner configured as described above is cooled while the air in the room sucked through the intake port I passes through the heat exchanger 15 as the cross flow fan 13 is operated. After passing through the fan 13 is moved to the discharge port (O) side along the flow path guide 17 is discharged into the room through the discharge port (O) to achieve the cooling of the room.

At the same time, the air sucked into the suction port I passes through the air filter 31 and the dust collector 35 to remove the contaminants, and then, to some extent, the purified air is taken out to the room again.

However, by employing an air purification system composed of an air filter 31 and a dust collector 35, such as the wall-mounted air conditioner of the prior art, it basically responds to various contaminants / moisture / odors generated indoors. In particular, contaminants such as fine particles, carbon dioxide, and volatile organic compounds are not easily removed by the air purification system.

Therefore, the introduction of a ventilation system in general air conditioners also introduces an appropriate amount of outside air into the room, and the demand for maintaining the quality of indoor air in a comfortable state is increasing. The air conditioner applying the ventilation system is largely equipped with a ventilation system inside the air conditioner. There is a separate product type that adds a ventilation effect by combining the product mounting type using a pipe passage from one side without a separate hole, and a separate ventilation kit (kit) to the general air conditioner.

However, the air conditioner to which the ventilation system is applied as described above can improve the quality of the indoor air more actively by realizing proper ventilation with the operation of the air conditioner, but applying the ventilation system through the existing piping passage or installing it separately As a result, the structure of the overall air conditioner is complicated, and the additional cost increases.

The present invention has been made to solve the above problems, by connecting a centrifugal fan for sucking and supplying external air to the shaft of the cross flow fan forcibly flowing the indoor air at the time of air conditioner operation without using a separate motor It is an object of the present invention to provide an air conditioner equipped with a ventilation device capable of realizing a more comfortable air conditioning environment by introducing external air into a room.
