Description

Decoration frame mounting structure of indoor unit for air conditioner

The present invention relates to an air conditioner, and more particularly, to an indoor unit that sucks heat in a space for air conditioning therein, heat exchanges it, and discharges the air to a space for air conditioning.

1 and 2 illustrate an indoor unit configuration of a conventional air conditioner. According to this, the casing 1 forms the exterior of the indoor unit. The casing 1 has a flat rectangular shape, and its length in the vertical and horizontal directions is relatively larger than the width before and after. A suction part 3 is formed on the front surface of the casing 1, which becomes a passage for sucking air in a space for air conditioning into the casing 1.

The heat exchanger 5 is installed at the rear of the suction part 3. The heat exchanger 5 is a portion in which heat exchange between the refrigerant of the heat exchange cycle and the air sucked in the space for air conditioning through the suction unit 3 is performed. The heat exchanger 5 is formed in a quadrangle so that the suction part 3 and its area correspond. In the center of the heat exchanger 5, a through hole 6 is formed in order to avoid interference between the motor 7 and the turbofan 9, which will be described below.

The motor 7 is installed inside the casing 1. The rotation shaft of the motor 7 is installed in the direction from the rear of the casing 1 to the front, and the turbo fan 9 is installed. The turbo fan 9 is a portion that provides a motive force for the flow of air in the interior of the indoor unit, and sucks air in the direction of the rotation axis from the front and blows it in the centrifugal direction.

Upper, lower, left, and right sides of the casing 1 are provided with discharge ports 11 for discharging air blown by the turbo fan 9 into a space for air conditioning. Discharge port vanes 13 are respectively installed in the discharge ports 11 to adjust the direction of air discharged from the discharge ports 11.

Meanwhile, an orifice 15 is installed between the heat exchanger 5 and the turbo fan 9. An orifice hole is formed in the center of the orifice 15 so that the air passing through the heat exchanger 5 is the turbo. Guided to fan 9.

According to the prior art having such a configuration, the indoor unit of the air conditioner is operated as follows.

When the air conditioner is driven, a relatively low temperature refrigerant is transferred to the heat exchanger 5 while the heat exchange cycle is operated. Then, the turbo fan 9 is rotated by the motor 7 to suck air in the space for air conditioning.

That is, when the turbo fan 9 is rotated, air in the space for air conditioning is sucked into the casing 1 through the suction unit 3. In addition, the air sucked through the suction unit 3 is heat-exchanged while passing through the heat exchanger 5, and becomes cold air having a relatively low temperature.

The cool air generated in the heat exchanger 5 is sucked into the turbo fan 9 and discharged in the centrifugal direction of the turbo fan 9. The air discharged from the turbo fan 9 is discharged into the space for air conditioning through the discharge holes 11 formed on the upper, lower, left, and right sides of the casing 1. At this time, the discharge port vane 13 of the discharge port 11 is opened to control the discharge direction of the discharged cold air.

However, the indoor unit of the air conditioner according to the prior art as described above has the following problems.

The indoor unit is installed in a space for air conditioning, and the appearance of the indoor unit has a great influence on the interior of the room. In particular, in the case of the indoor unit to be used on the wall can be obtained a lot of interior effect as if the painting. However, the conventional indoor unit has a problem such as using a separate fastening component in order to install a configuration for aesthetic appearance.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to make the appearance of the indoor unit of the air conditioner more beautiful.

Another object of the present invention is to be able to more easily mount the components constituting the appearance of the indoor unit of the air conditioner.
