し、モータｃの寿命が心配されていた。 However, with this structure, heat is radiated from motor c only by natural convection of air, so the heat radiating effect is small. Especially when the ambient temperature in the room is high, the temperature of motor c increases because the heat radiating effect is not sufficient. , there were concerns about the lifespan of motor c.

気穴３ａ側に負圧を生じさせる。 In the figure, reference numeral 1 denotes an indoor unit main body (hereinafter simply referred to as the main body), which internally includes a heat exchanger 5, a wind circuit 6 equipped with a once-through fan (not shown), etc., and a motor 2 for driving the once-through fan. storage space 7
Equipped with: This storage space 7 is formed by the case cover 3. Reference numeral 1a denotes a cooling hole formed on the back surface of the main body 1, which opens into the storage space 7. 3a is the wind circuit 6 of the case cover 3
A ventilation hole provided on the side opens into the storage space 7. Reference numeral 4 denotes a pressure guide plate having an L-shaped cross section and provided on the main body 1, and is provided on the windward side of the heat exchanger 5, and generates negative pressure on the side of the ventilation hole 3a.
上記構成において、第２図、第３図により空気

スカバー３の通気穴３ａから導圧板４で形成され
る負圧域へ流れ、そして風回路６内へ流れ込む。 First, when the air conditioner is operated, air is sucked in from the front of the heat exchanger 5 and flows into the main body 1. On the other hand, the heat in the atmosphere of the motor 2 disposed inside the storage space 7 is absorbed by air entering from the cooling hole 1a provided in the main body 1 by the pressure conduction plate 4 attached to the heat exchanger 5, and 2 , flows from the ventilation hole 3 a of the case cover 3 to the negative pressure area formed by the pressure plate 4 , and then flows into the wind circuit 6 .
したがつて、モータ２の範囲気の熱を強制的に
対流させるため、モータ２を効果的に冷却でき、
モータ２の温度上昇を防ぐことができる。 Therefore, since the heat of the air within the motor 2 is forced to convect, the motor 2 can be effectively cooled.
It is possible to prevent the temperature of the motor 2 from rising.

る効果を奏する。Effects of the Invention As described above, in the present invention, a negative pressure is generated behind the pressure plate in order to prevent the flow of air toward the storage space by the pressure plate. As a result, hot air around the motor can be forced to flow out from the communication hole provided on the end surface of the case cover on the side of the heat exchanger. Therefore, the motor can be effectively cooled, the life of the comb motor can be extended, and the quality of the motor can be stabilized.
