Benefits of technology
[0017]As described above, according to the present invention, the rotation attitude of the lateral louver is controlled so that, when the lateral louver is held in the upward blowout attitude, the air blowing guide passage is formed by cooperation of the upper surface of the lateral louver with the upper surface of the straightening plate. Thereby, the lateral louver and the straightening plate are integrated together in a pseudo manner, so as to form the air blowing guide passage which is longer than the air blowing guide passage of the lateral louver itself. As a result, it is possible to provide a blowing structure which is compact and capable of reducing cost while improving the air blowing performance by combining the existing straightening plate and the existing lateral louver with each other.
Problems solved by technology
Therefore, in an air conditioning device whose size and cost are to be reduced, it is difficult to improve the air blowing performance by using a configuration in which both the auxiliary louver and the air guide panel are simultaneously assembled.
However, when the lateral louver which freely changes the air flow direction is used in a portion of the blowout port, the air blowing performance is influenced by the rotational angle and the shape of the lateral louver, and further by the operation torque of the lateral louver, the increase in the depth length of the auxiliary louver is limited and may result in cost increase.

Embodiment Construction
[0062]An embodiment according to the present invention will be described with reference to the accompanying drawings. The present embodiment is described by using, as an example, an indoor unit of a separate type air conditioner which is an example of an air conditioning device. In the air conditioner of this type, a heat exchanger housed in an indoor unit, and a compressor, a four way valve, an outdoor heat exchanger, and a restriction apparatus (all not shown), which are housed in an outdoor unit (not shown), are connected by a refrigerant pipe to form a refrigerating cycle, and thereby various modes of operation, such as cooling, heating, and dehumidification operations, can be performed.
[0063]As shown in FIG. 2, in the indoor unit, a suction port 2 for sucking indoor air is formed in the upper surface of a cabinet 1, and a blowout port 4 is formed in an opening 3 below the front surface of the cabinet 1. In the inside of the cabinet 1, an air passageway 5 extending from the suct...

An air flow direction changing device of an air conditioning device according to the present invention includes: a lateral louver which is rotatably provided on the front side of a blowout port of a cabinet; a control section which changes the blowout direction of air sent from a fan by rotatably driving and controlling the lateral louver in the front surface of the blowout port; and a straightening plate which is provided on the rear side of the lateral louver in the blowout port and straighten the air flow from the fan located on the rear side in the passageway, and is configured such that the control section improves the blowing performance by controlling the rotation attitude of the lateral louver in such a manner that, when the lateral louver is held in an upward blowout attitude, an air blowing guide passage longer than the depth length of the lateral louver itself is formed by cooperation of the upper surface of the lateral louver with the upper surface of the straightening plate.
Description
TECHNICAL FIELD[0001]The present invention relates to an air conditioning device including an air flow direction changing device which changes the direction of air blown out from a blowout port of a cabinet.BACKGROUND ART[0002]When the air flow direction control of an air passageway is performed in an air conditioning device, an air guide panel configured to freely open and close a front opening of a cabinet, and an auxiliary louver arranged near a blowout port located on the rear side of the air guide panel are controlled (see Patent Literature 1). However, since the air guide panel and the auxiliary louver are respectively arranged near the blowout port and also independently controlled, the air blowing performance is influenced by the length of the auxiliary louver and of the air guide panel. Therefore, in an air conditioning device whose size and cost are to be reduced, it is difficult to improve the air blowing performance by using a configuration in which both the auxiliary lo...
