Apparatus for redirecting an air flow and air conditioner having the same

Abstract

An air conditioner, especially to an apparatus for redirecting wind in an indoor unit of the air conditioner is disclosed. A scroll guide provided so as to form an air duct at the circumference of a centrifugal fan for sucking and discharging the interior air so that the interior air can pass through a heat exchanger is installed in a rotation controllable state. Wind direction patterns can be regulated in various states by rotating the scroll guide by a predetermined angle and converting the setting position of an air discharge opening according to the operation mode. The degree of freedom relative to wind redirection of the discharge air can be improved by a variable air duct and the product efficiency and the reliability can be improved through improvement of the wind amount efficiency and reduction of noise.

Description

technical field [0001] The present invention relates to an air conditioner, and more particularly, to an air direction adjusting device of the air conditioner for guiding the discharge direction of conditioned air by selectively changing the air duct. Background technique [0002] In recent years, people's desire to pursue a comfortable living environment for living space and further for office space is increasing, so the use of air conditioners such as refrigeration and heating machines is increasing day by day. [0003] This type of air conditioner mainly performs a cooling function or a heating function for maintaining optimal temperature and humidity according to the climatic conditions and indoor environment in different seasons, especially for the air conditioner (Aircon) used for cooling, except for large-scale air conditioners. In addition to the research and development of upgrading, upgrading, and systematic research and development, many research and development t...

Problems solved by technology

Therefore, it is impossible to adjust the wind direction according to the user's operation selection, and it is difficult to realize various wind direction adjustment functions, and there is a problem that there is a limitation in optimizing the cooling function and efficiency.

[0011] On the other hand, when adjusting the wind direction of the cool air discharged from the internal ventilation passage of the cabinet 10 to the outside by selectively controlling the opening and closing states of the above-mentioned shutter 11b and blade 11c, there is the following problem: Around the unclosed shutter 11b and vane 11c, noise occurs due to the blocking and leakage of the cold air blown out through the cold air outlet of the air passage.

[0012] In addition, there is a problem that the discharged cold air that is blocked from being discharged to the outside of the cabinet 10 by the shutter 11b or vane 11c that is controlled to be closed for setting the wind direction interferes with being discharged to the cabinet through the normal open path. 10's external air-conditioning, so it affects the state of the wind direction and makes it unstable, thus reducing the air volume efficiency and air-conditioning function

[0013] In addition, for the conventional air conditioner as described above, there are actually restrictions on the design and production technology of the above-mentioned shutter 11b and vane 11c, which are designed to have an opening angle of approximately 120°, so that the opening ratio is limited.

[0014] As a result, the degree of freedom to control the angle of the wind direction for blowing out cold air is limited, and there is a problem that it may cause a decrease in product performance and reliability due to an increase in noise and a decrease in air volume.
