Reference numeral 90 is a control box disposed on one side of the cabinet 55 and mounted with electrical components for driving a duct type air conditioner therein.

Looking at the operation of the present invention configured as described above are as follows.

First, when the blower fan 56b is driven, foreign substances such as air and dust in the air-conditioning chamber A are sucked through the suction duct 70 to open the inside of the filter case 62 of the air purification unit 60. Will pass.

At this time, foreign matter such as dust passing through the filter case 62 is filtered by the air filter 64, and only air is sucked into the air suction port 52 of the cabinet 55.

The air sucked into the air inlet 52 of the cabinet 55 is heat-exchanged with the refrigerant while passing through the heat exchanger 57, and then is sucked into the housing 56a and discharged through the air outlet 53. After being guided to the inside of the duct 80 is discharged through the discharge duct 80 to the air-conditioned chamber (A) to cool or heat the air-conditioned chamber.

On the other hand, if the above operation is performed for a long time, foreign matter is accumulated in the filter 64, when such foreign matter is excessively reduced the intake amount of air through the air inlet 52, the performance of the duct type air conditioner Because of this deterioration, the filter 64 should be cleaned periodically or replaced with a new filter.

In this case, as shown in FIG. 4, the operator rotates the ceiling plate 50 ′ below the air purification unit 60 to open the bottom side of the air purification unit 60 and the filter case 62. After the filter holder 66 is separated, the filter 64 is pulled out through any one of the filter insertion holes 62b, 62c, and 62d. The filter 64 is easily and quickly moved inside the filter case 62. It can be withdrawn.

On the other hand, when the filter 64 in which foreign matter is removed or a new filter is to be mounted on the filter case 62, the filter 64 is inserted into the bottom insertion hole 62b or the side insertion hole 62c of the filter case 62. When the filter holder 66 is fixed to the filter case 62 so as to block the bottom inserting hole 62b or the side inserting holes 62c and 62d after being inserted through the 62d, the filter 63 The filter case 62 may be mounted inside the filter case 62 to purify the air passing through the filter case 62.

Meanwhile, the suction duct 70 is fixed to the filter case 62 fixed to the cabinet 55 while the filter 64 is attached or detached, and the worker removes the suction duct 70. The filter 64 can be easily attached or detached without disassembling.
