  • the vertical blade 20 is already at the original position at the time of stop (the blade Since the piece 201 is in the second state), the time to the origin position is omitted. Therefore, the time required from the start of operation until the vertical blades 20 return to the position immediately before the previous stop is shorter than before, and accordingly, the user feels a longer time from the start of operation to the air blowing operation. Such an unpleasant feeling can be reduced.
  • half of the plurality of blade pieces 201 have their tips directed to the right side RF side and the other half directed to the left side LF side.
  • the present invention is not limited to this. The same effect can be obtained even if the tip of the piece 201 is directed to either the right side RF side or the left side LF side.
  • (3) Features (3-1) In the air conditioning indoor unit 10, the vertical blades 20 are disposed in the main body casing 13, and the air blowing state from the air outlet 15 can be switched between the first state and the second state.
  • the first state is a state of blowing out to the front side of the main body casing 13
  • the second state is a state of blowing out to the side surface side of the main body casing 13.
  • control unit 40 places the auxiliary blade 130 after the vertical blade 20 is in the second state when the operation is stopped and closes the vertical airflow direction adjusting blade 30, the vertical blade 20, the vertical airflow direction adjusting blade 30, the auxiliary blade 130, Does not interfere, and the degree of interference is small. Therefore, it is possible to take a longer dimension in the blowing direction of the vertical blades 20 and to direct the air at the time of horizontal blowing in the target direction, and also due to interference between the vertical airflow direction adjusting blades and the vertical blades when the operation is stopped. Plastic deformation of the vertical blades can be prevented.
  • the second state of the vertical blade 20 when the vertical airflow direction adjusting blade 30 is in the closed state is the origin position of the vertical blade 20.
  • the origin return of the vertical blade 20 when the operation is resumed is omitted.
  • the control unit 40 stores the position of the vertical blade 20 immediately before the operation is stopped, and returns the position to the position when the operation is resumed.
  • the length of the vertical blades along the air blowing direction is set larger than the conventional one, and air can be efficiently blown out in the target direction. Therefore, it is useful for an air-conditioning indoor unit of a suction port automatic opening / closing type.

Abstract

La présente invention se rapporte à une unité intérieure de climatisation qui peut efficacement souffler de l'air dans une direction visée pendant le soufflage gauche-droite de l'air soufflé. Dans l'unité intérieure de climatisation (10), une pale verticale (20) est disposée dans une enveloppe de corps principal (13) et peut commuter l'état d'air soufflé depuis un orifice de sortie (15) dans un premier état ou dans un second état. Le premier état est un état qui souffle vers l'avant de l'enveloppe de corps principal (13), et le second état est un état qui souffle vers les côtés de l'enveloppe de corps principal (13). Lorsque le fonctionnement d'arrête, une unité de commande (40) amène la pale verticale (20) à se trouver dans le second état et ensuite range une pale auxiliaire (130) et amène une pale de réglage (30) de direction de vent verticale à se trouver dans un état fermé, et il n'y ainsi pas d'interférence ou un faible degré d'interférence entre la pale verticale (20) et la pale de réglage (30) de direction de vent verticale et la pale auxiliaire (130).
