In particular, the present invention relates to an air conditioner having an air curtain function in which the air conditioning function can be performed separately for each zone even in the same room divided by a thick wall.

A general air conditioner is composed of an outdoor unit that supplies hot heat and an indoor unit that supplies cold air. Of course, by allowing the refrigeration cycle to run in the opposite direction, it is possible to allow the cold cold air to diverge to the outdoor unit, and to provide warmth to the room.

However, in the conventional air conditioner, a single interior space divided by a thick wall forms a single system. Therefore, there is a disadvantage in that the air conditioning is simply performed in the entire indoor space without providing a function of allowing the air conditioner to be selectively partitioned internally in the room.

As such, since a single indoor space is performed as an air conditioner with a single control volume as a whole, since air conditioning is performed to a place where a user does not exist, energy consumption is increased. For example, even if the user is in an indoor living room, since air conditioning is performed for the entire interior space such as a bedroom, air conditioning is performed for the entire region such as a bedroom and a kitchen, and for air conditioning of these spaces. There was a disadvantage of using energy that is not needed.

At this time, not only the separate air conditioner for the indoor air conditioner to be performed, but also provided with a separate air curtain in the door, the two devices are used separately, there was inconvenience in use.

The present invention has been proposed in order to solve the above problems, it is proposed to propose an air conditioner with an air curtain function that can improve the convenience of use by implementing the function of the air conditioner and the function of the air curtain to a single article. The purpose.

In addition, the present invention is provided with an air curtain function to increase the ease of use and save energy by actively maintaining a different temperature for each space, when divided into different spaces having a temperature difference even in the same indoor space. It is aimed at suggesting the air conditioner which became.

In addition, an object of the present invention is to propose an air conditioner equipped with an air curtain function to enable the user to actively implement the air conditioning environment only inside the living space.
