Problems solved by technology
However, in the indoor unit described in Patent Document 1, no consideration is given to the flow path of the air in the air-conditioned space sucked in by the suction port surrounded by each blower port.
Therefore, the indoor unit described in Patent Document 1 is difficult to suck in the air of the air-conditioning target space from the suction port due to the angle of the conditioned air blown out from each blower port.
Therefore, in the indoor unit described in Patent Document 1, there is a problem of so-called short-circulation in which the conditioned air blown out from the blower port is sucked in again from the suction port.

Embodiment approach
[0019] figure 1 It is a perspective view which looked at the indoor unit of the air conditioner which concerns on embodiment of this invention from the obliquely lower side. figure 2 is in figure 1 A longitudinal sectional view of the indoor unit of the air conditioner according to the embodiment of the present invention cut at Z-Z in FIG. in addition, image 3 It is a bottom view of the indoor unit of the air conditioner concerning embodiment of this invention.
[0020] The indoor unit 100 of the present embodiment is installed so as to be embedded in a ceiling of an air-conditioning target space such as a room or suspended from the ceiling of an air-conditioning target space. This indoor unit 100 includes a casing 10 in which a suction port 13 and blowing ports 14 to 17 are opened on the lower surface. The casing 10 is, for example, a substantially rectangular parallelepiped box with a hollow inside. The suction port 13 is opened substantially in the center of the lowe...

An air-conditioning-apparatus indoor unit includes a casing having an air inlet and four air outlets arranged in a lower surface portion such that the four air outlets surround four sides of the air inlet, and lateral air flow direction members adjusting a lateral angle of air blown through the air outlets. When one of the air outlets is defined as a first air outlet, the air outlets next to the first air outlet are defined as a second air outlet and a third air outlet, the air outlet facing the first air outlet across the air inlet is defined as a fourth air outlet, and when the lateral air flow direction member disposed in the first air outlet is in a state for blowing the air toward the second air outlet, the lateral air flow direction member disposed in the second air outlet is in a state for blowing the air toward the first air outlet, the lateral air flow direction member disposed in the third air outlet is in a state for blowing the air toward the fourth air outlet, and the lateral air flow direction member disposed in the fourth air outlet is in a state for blowing the air toward the third air outlet.
Description
technical field [0001] The present invention relates to an indoor unit of an air conditioner installed so as to be buried in a ceiling of an air-conditioning target space or suspended from the ceiling of an air-conditioning target space. Background technique [0002] The indoor unit of the conventional air conditioner has the structure installed so that it may be embedded in the ceiling of an air-conditioning target space, or may be suspended from the ceiling of an air-conditioning target space. As a conventional indoor unit installed in this way, for example, it is known to have: a suction port opened in the substantially central portion of the lower surface portion of the housing, and four outlets opened in a manner surrounding the suction port on the lower surface portion, An indoor unit that can blow out conditioned air (air that has been heat-exchanged with a heat exchanger) to the surroundings. In addition, an indoor unit of an air conditioner is proposed, that is, an...
