Referring to the accompanying drawings, a preferred embodiment of the present invention will be described.

As shown below in FIG. 1 , an air conditioner having an air cleaning function according to an embodiment of the present invention includes a filter unit disposed in a main body intake port 2a formed in a main body case. The main body case includes a housing 1 with an open front, a front panel 2 disposed on the open front surface of the housing 1 and having a main body intake port 2a, and a front side of the main body intake port 2a of the front panel 2. and a front grill 3 having a grill intake 3a formed therein.

The filter unit includes a filter panel 10 disposed at the intake port 2a of the main body and formed with first and second filter intake ports 12, a filter medium 20 disposed at the first filter intake port 13, and an air cleaning function. It includes a valve 30 that opens the first filter inlet 13 when in operation and opens the second filter inlet 12 when the air cleaning function is not in operation.

The filter panel 10 may be detachably coupled to the main body case by screw fastening.

The first and second filter intake ports 12 may be formed in semicircular regions obtained by dividing an imaginary circle having a predetermined radius into two on the filter panel 10 . For example, the first filter inlet 13 may be formed in the lower semicircular area of the imaginary circle, and the second filter inlet 12 may be formed in the upper semicircular area. In particular, the first and second filter intake ports 12 are formed symmetrically with respect to a first axis passing through the center of an imaginary circle and have the same size and shape, so that a uniform amount of air is sucked in regardless of whether the air cleaning function is operating or not. can make it possible

Each of the first and second filter inlets 12 may be formed of a pair of equally divided symmetrical parts about a second axis passing through the center of the imaginary circle and perpendicular to the first axis.

A filter frame 14 may be disposed on the filter panel 10 to surround the first filter inlet 13 and support the filter medium 20 . The filter frame 14 may be integrally protruded from the filter panel 10 . The filter frame 14 may be formed in a rectangular shape corresponding to the filter medium 20 . The filter medium 20 can be replaced by sliding on the filter frame 14 in a direction perpendicular to the filter panel 10 and attaching or detaching it.

An appropriate filter material 20 may be selected from among various types according to the purpose of operating the air cleaning function. For example, the filter medium 20 may be a HEPA filter capable of purifying radioactive particles in the air.

The valve 30 may have a rotational structure corresponding to the first and second filter intake ports 12 arranged in an imaginary circle. That is, the valve 30 is coupled to the filter panel 10 so as to be rotatable about the center of an imaginary circle, and the pair of first filter intake ports 13 or the pair of second filter intake ports 12 are connected together. A semicircular cover 31 that can be shielded, a hub 32 extending from the cover 31 and disposed at the center of an imaginary circle, and coupling the hub 32 to the filter panel 10 in a rotatable manner. It may include a rotation axis that does. The valve 30 may rotate the cover 31 by the driving force of a motor connected through a rotating shaft and a belt. On the other hand, the filter panel 10 may be protruded with a shaft coupling portion 15 to which a rotating shaft is coupled to the center of the virtual circle.

Meanwhile, the present invention may further include an environmental sensor 60 for measuring ambient air environmental factors in order to operate the air cleaning function. The environment sensor 60 includes a fine dust sensor 60 for detecting fine dust, a gas sensor 60 for detecting harmful gas, and an odor sensor 60 for detecting odor. A recessed sensor 60 accommodating portion 2b may be formed on the outer side of the main body case so that the environment sensor 60 can be easily attached or detached from the PCB built in the main body case. That is, the sensor 60 accommodating part 2b is located on one side of the terminal 52 side of the PCB built in the body case and accommodates the environmental sensor 60 coupled to the terminal 52 of the PCB, and the environment sensor A terminal 52 hole through which the PCB terminal 52 is exposed may be formed so that 60 can be coupled to the PCB terminal 52. Accordingly, the environment sensor 60 can be easily and selectively mounted on the PCB according to the surrounding environment and replaced.

A detailed look at the effect of the air conditioner having an air cleaning function according to an embodiment of the present invention configured as described above is as follows.

When the air cleaning function is activated as a result of detection by the environmental sensor 60 or the like, the valve 30 opens the first filter intake port 13 and closes the second filter intake port 12, so that air flows through the first filter intake port ( 13), and at this time, it is purified by the filter medium 20, and the air cleaning function can be operated.

On the other hand, when the air cleaning function is not required as a result of detection by the environmental sensor 60, etc., the first filter inlet 13 is closed by the valve 30 and the second filter inlet 12 is opened so that air is supplied to the filter medium 20. ) can be directly inhaled without passing through.
