Description

Indoor unit of air conditioner

The present invention relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of an air conditioner capable of sterilizing a heat exchanger.

In general, an air conditioner is used to cool or heat a room or purify the air by using a refrigeration cycle of a refrigerant consisting of a compressor, a condenser, an expansion mechanism, and an evaporator to create a more comfortable indoor environment for a user. .

The separate type and the integrated type are functionally the same, but the separate type connects the indoor unit and the outdoor unit separated by the refrigerant pipes by installing the cooling / heating unit in the indoor unit and the heat radiating / cooling and compression unit in the outdoor unit, and the integrated type by cooling heat dissipation. Integrate the function of the hole in the wall of the house or hang the device on the window is installed directly.

6 to 8, the indoor unit of the conventional split type air conditioner includes a base 101, a cabinet 102 disposed on an upper side of the base 101 and an open front surface thereof, and the cabinet 102. The front panel 104 is coupled to the front surface of the front panel, and an air outlet 104a is formed at an upper portion thereof, and an air inlet 104b is formed at a lower portion thereof, and a lower portion is installed between the cabinet 102 and the front panel 104. And a blower 120 and a heat exchanger 130 installed above the blower 120.

The front panel 104 is disposed between the front upper panel 105 having the air discharge port 104a formed therebetween, and the center lower portion of the front upper panel 105 and the base 101. It consists of a front lower panel 106 forming the air inlet 104b between the lower sides of both sides, and a suction grill 107 provided between the side end of the front lower panel 106 and the lower portion of the cabinet 102. do.

Below the heat exchanger 130, a drain pan 132 for receiving condensate dropped from the surface of the heat exchanger is disposed, and the drain pan 132 has a drain hose 134 for draining the condensate to the outside. Connected.

The conventional air conditioner indoor unit configured as described above, when the blower 120 is driven, the air of the indoor side is sucked into the indoor unit through the air inlet 104b, and passes through the heat exchanger 130 to cool / cool. After heated, the air is discharged back into the room through the air outlet 104a to cool / heat the room.

When the indoor unit of the air conditioner as described above has a cooling function, condensed water is generated by condensation / condensation of moisture in the air on the surface of the heat exchanger 130, and the generated condensate flows under the heat exchanger 130. After gathered in the drain pan 132, and discharged to the outside through the drain hose 134, the remaining moisture that has not been condensed water remains in the heat exchanger 130, if the air conditioner is not used for a certain period of time 4) mold is formed.

The mold generated as described above is discharged of unpleasant air through the outlet when the air conditioner is used again after a certain period of time, thereby giving a user a bad smell and discomfort.

In order to remove the mold generated in the conventional heat exchanger 130, the front panel 104 is opened, the mold removing liquid is sprayed using a mold removing spray, and then the mold is removed by covering the front panel 104.

However, the method for removing the mold generated in the heat exchanger of the conventional air conditioner is to open the front panel 104 of the indoor unit at any time in order to remove the mold of the indoor unit and sprinkle the mold removal liquid directly on the heat exchanger 130 and then again the front panel ( There is considerable inconvenience as the 104 must be closed.
