Benefits of technology

[0009]According to the invention, the situation in the room (for example, where a person is present) can be detected by the human detection sensor. Then, by controlling the air volume, the orientation of the horizontal wind direction control vane, and the orientation of the vertical wind direction control vane of each of the fans according to detected results of the human detection sensor, airflows of different air volumes can be distributed individually to different places in the room. Controlling each air volume of the fans does not mean to differ each of the air volumes of each fans. As a matter of course, the air volumes of some fans may be the same.

Problems solved by technology

Therefore, distribution of airflows different in air volume individually to different places in the room were unfortunately not possible.

embodiment 1

[0034]FIG. 1 is a vertical cross-sectional view illustrating an indoor unit (referred to as “indoor unit 100”) of an air-conditioning apparatus according to Embodiment 1 of the invention. FIG. 2 is a perspective view illustrating the indoor unit shown in FIG. 1. In the description of Embodiment 1 and other embodiments described later, the left side in FIG. 1 is defined as the front side of the indoor unit 100. Referring now to FIG. 1 and FIG. 2, a configuration of the indoor unit 100 will be described.

(General Configuration)

[0035]The indoor unit 100 supplies air-conditioned air to an area to be air-conditioned such as an indoor space by utilizing a refrigerating cycle circulating a refrigerant. The indoor unit 100 mainly includes a casing 1 formed with suction ports 2 for taking in indoor air and a blow-out port 3 for supplying air-conditioned air to the area to be air-conditioned, fans 20 housed in the casing 1 and configured to take in the indoor air from the suction ports 2 and b...

embodiment 2

[0118](Dividing Vane into Plurality of Parts)

[0119]When controlling the vertical wind direction control vane 70, the horizontal wind direction control vane 80, and the air volume of each fans 20 on the basis of the results of detection by the infrared ray sensor 410, dividing the vertical wind direction control vane 70 and the horizontal wind direction control vane 80 into a plurality of parts and controlling the same individually is recommended. Accordingly, comfort can further be improved. In Embodiment 2, items not specifically described are the same as those in Embodiment 1, and the same numbers reference the same functions and configurations in the description.

[0120]FIG. 11 is a front cross-sectional view illustrating the indoor unit according to Embodiment 2 of the invention. FIG. 12 is a perspective view illustrating the same indoor unit. FIG. 11 is a front cross-sectional view taken along the substantially center portions of the fans 20.

[0121]In the indoor unit 100 according...

embodiment 3

[0128](Dividing Vane into Number of Parts as Same as the Number of Fans)

[0129]By increasing the number of divisions of the vertical wind direction control vane 70 and the horizontal wind direction control vane 80, the comfort can further be improved. Also, by employing the number of divisions of the vertical wind direction control vane 70 and the horizontal wind direction control vane 80 as many as the number of the fans 20, the comfort can further be improved. In Embodiment 3, items not specifically described are the same as those in Embodiment 1 and Embodiment 2, and the same numbers reference the same functions and configurations in the description.

[0130]FIG. 13 is a front cross-sectional view illustrating the indoor unit according to Embodiment 3 of the invention. FIG. 14 is a perspective view illustrating the same indoor unit. FIG. 13 is a front cross-sectional view taken along the substantially center portions of the fans 20. The indoor unit 100 shown in FIG. 13 and FIG. 14 sh...

Abstract

An indoor unit includes: a casing formed with a suction port and a blow-out port; a plurality of fans provided in parallel in the casing; a heat exchanger provided on the downstream side of the fans and on the upstream side of the blow-out port; a horizontal wind direction control vane provided at the blow-out port to control the horizontal direction of an airflow blown out from the blow-out port; a vertical wind direction control vane provided at the blow-out port to control the vertical direction of the airflow blown out from the blow-out port; and an infrared ray human detection sensor configured to detect the position of a person present in a room, and air volumes, the orientation of the horizontal wind direction control vane, and the orientation of the vertical wind direction control vane of the fans are each controlled according to results of detection by the infrared ray sensor.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an indoor unit having a fan and a heat exchanger housed in a casing and an air-conditioning apparatus having the indoor unit.[0003]2. Description of the Related Art[0004]Conventionally, an air-conditioning apparatus (more specifically, an indoor unit) having a vertical wind direction control vane divided into three parts and a horizontal wind direction control vane and configured to control the direction of an airflow blown out from a blow-out port using the vertical wind direction control vane divided into three parts and the horizontal wind direction control vane has been proposed. More specifically, two parts of the vertical wind direction control vane other than the central part are controlled in the closing direction of the blow-out port and the horizontal wind direction control vane is controlled to throttle the airflow blown out from the blow-out port, so that the velocity of the ...
