Further, when water is applied to try to clean the heat exchanger, the water also becomes applied to electrical parts and the like disposed on the side of the heat exchanger, and there is the potential for drawbacks such as insulation failure to occur. For this reason, the heat exchanger cannot be cleaned with water even when the heat exchanger is dirty. Thus, it is difficult to say that the heat exchanger can always be kept clean.

- An air conditioner pertaining to a third invention comprises the air conditioner of the first or second invention, further comprising a casing that houses inside the fan unit, the heat exchanger, and the partition member. Additionally, the casing includes an open panel that allows the space on the upstream side of the heat exchanger in the flow of the air formed by the fan unit to be exposed for performing maintenance of the heat exchanger
- Here, the casing that houses inside the fan unit, the heat exchanger, and the partition member includes an open panel for performing maintenance of the heat exchanger.

- An air conditioner pertaining to a fifth invention comprises the air conditioner of the fourth invention, wherein the partition member is disposed in the vicinities of fins disposed on both ends of plural fins disposed on the surface of the heat exchanger.
- Here, the partition member is disposed in the vicinities of fins disposed on both ends of the heat exchanger.
- Thus, the space where the refrigerant pipe and electrical wiring connected to the side surface of the heat exchanger are installed and the space on the upstream side of the heat exchanger can be reliably partitioned from each other, and occurrences of drawbacks can be avoided even when the heat exchanger is cleaned with water.
- An air conditioner pertaining to a sixth invention comprises the air conditioner of any one of the first to fifth inventions, further comprising a drain pan that is disposed below the heat exchanger and receives drain water generated in the heat exchanger.
- Here, a drain pan is disposed below the heat exchanger.

Additionally, the space A on the upstream side of the exposedheat exchanger 2 and the spaces B and C on the sides of theheat exchanger 2 are partitioned from each other by thepartition members - Ordinarily, it is preferable to clean a heat exchanger of this configuration by applying water to it because the heat exchanger can be cleaned extremely efficiently and the applied water can be discharged to the outside via a drain pan installed below the heat exchanger. However, in this case, when water is applied to the heat exchanger, there has been the potential for electrical parts and the like around the heat exchanger to become wet and for drawbacks to occur. For this reason, conventionally, it has been difficult to clean the heat exchanger by applying water to it.
- Given this, the air conditioner
indoor unit 50 of the present embodiment is disposed with thepartition members heat exchanger 2 from the spaces B and C on both sides of theheat exchanger 2 where electrical parts and the like are installed, so that occurrences of drawbacks in electrical parts and the like may be avoided even when theheat exchanger 2 is cleaned using water. - Thus, it becomes possible to clean the
heat exchanger 2 by applying water to theheat exchanger 2 because the water applied to theheat exchanger 2 can be prevented from being applied to the electrical parts and the like. - Further, in regard to the
refrigerant pipes heat exchanger 2, although it is easy for dirt to accumulate because pipes with small diameters are incorporated therein and their structures are complex, it can be made difficult for dirt to accumulate on therefrigerant pipes partition members - (2)
- The air conditioner
indoor unit 50 of the present embodiment is disposed with the maintenance panel that allows theheat exchanger 2 to be exposed to the outside as part of thecasing 1 configuring the outer enclosure. - Thus, the
heat exchanger 2 can be easily cleaned in a state where themaintenance panel 10 has been removed to expose theheat exchanger 2. - (3)
- In the air conditioner
indoor unit 50 of the present embodiment, thepartition members heat exchanger 2. - Thus, the space A on the upstream side of the
heat exchanger 2 and the refrigerant pipe/electrical wiring installation space B and the refrigerant pipe installation space C can be partitioned from each other, and occurrences of drawbacks resulting from water being applied to therefrigerant pipes heat exchanger 2 is cleaned with water. - (4)
- In the air conditioner
indoor unit 50 of the present embodiment, thedrain pan 22 is disposed below theheat exchanger 2 that is cleaned with water. - Thus, water applied in order to clean the
heat exchanger 2 can be discharged to the outside via thedrain pan 22. Thus, cumbersome work such as wiping off water after theheat exchanger 2 has been cleaned with water becomes unnecessary. - An embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various modifications are possible within a range that does not depart from the gist of the invention.
