Description

Air Conditioner {Air Conditioner}

The present invention relates to an air conditioner, and more particularly, to an air conditioner including a filter device.

The duct type air conditioner exchanges heat with outside air and supplies it to the indoor space. Since the duct-type air conditioner heats outside air and introduces it into the indoor space, fine dust from the outside may flow into the indoor space.

In the duct-type air conditioner into which external air is introduced, foreign substances introduced together with the external air are easily introduced. Therefore, the duct-type air conditioner may place a filter at an inlet end through which external air is introduced.

In published utility model KR 20-2015-0004115 U, a filter disposed at an inlet of a duct type air conditioner is disclosed.

However, since external air directly flows into the duct-type air conditioner, a problem in which the filter is easily contaminated may occur.

An object to be solved by the present invention is to provide an air conditioner that increases the replacement cycle of a filter disposed in the air conditioner for supplying air to an indoor space by introducing outside air.

A sterilizer may be arranged to sterilize the filter. However, since the filter is disposed at the inlet end of the air conditioner, it can be assumed that the sterilizer is disposed downstream of the filter. Since this is not an area where foreign substances are mainly accumulated on the filter, the filter sterilizing effect may be weak. In addition, when UV light is irradiated from the inside of the air conditioner toward the filter disposed at the inlet, a problem in that the UV light is exposed to the outside may occur. The present invention is to solve the above problems, and to provide an air conditioner for securing an area of a sterilizer, effectively sterilizing a filter, and preventing external exposure of ultraviolet light.

When the filter is disposed inside the air conditioner, the filter may vibrate due to air flow. The present invention is to solve the above problem and to provide an air conditioner that solves problems such as noise caused by vibration of a filter.

When exposed to ultraviolet light of the sterilizer, the material of the buffer member that may be additionally disposed on the filter may be damaged. The present invention is to solve the above problem, and to provide an air conditioner capable of securing the reliability of a buffer member used for vibration damping.

The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the following description.
