Embodiment approach 1

[0039] The configuration of the air conditioner according to Embodiment 1 will be described. figure 1 It is an external perspective view showing a configuration example of the indoor unit of the air conditioner in Embodiment 1 of the present invention. figure 2 is viewed from the lower surface side figure 1 The top view of the indoor unit shown. image 3 yes figure 2 The cross-sectional schematic diagram of the indoor unit at the dotted line AA shown.

[0040] In this Embodiment 1, figure 1 The illustrated indoor unit 30 is a four-way ceiling box indoor unit. The indoor unit 30 has a rectangular parallelepiped casing. The indoor unit 30 is embedded in the ceiling of a room to be air-conditioned. Such as figure 2 As shown, the lower surface 31 of the indoor unit 30 is rectangular, and the lower surface 31 is exposed from the ceiling toward the indoor side. A rectangular suction port 3 is provided at the center of the lower surface 31 of the indoor unit 30 . A grid-l...

Embodiment approach 2

[0073] The air conditioner according to Embodiment 1 eliminates temperature unevenness in the space to be air-conditioned and reduces the user's feeling of wind by cooperating the vertical air direction adjustment parts 4a to 4d with the plurality of left and right air direction adjustment parts 6 . The air conditioner according to Embodiment 2 provides an air-conditioning target space in which temperature unevenness is further reduced during heating operation.

[0074] The configuration of the air conditioner according to Embodiment 2 is the same as that of the air conditioner 1 described in Embodiment 1, and therefore description of the configuration will be omitted in Embodiment 2. FIG. During heating operation, the warm air exhausted from the indoor unit 30 of the air conditioner 1 tends to stay on the ceiling surface, resulting in hot head and cold feet. As an example of a method of preventing such a state, the operation of the air conditioner 1 according to Embodiment 2 ...

Embodiment approach 3

[0082] The air conditioners of Embodiments 1 and 2 reduce temperature unevenness in the air-conditioned space by interlocking the vertical air direction adjusters 4a to 4d with the plurality of lateral air direction adjusters 6, thereby improving user comfort. The air conditioner according to Embodiment 3 has a human body position detection unit which detects the position of a person in the air-conditioning target space, and controls to automatically blow air to the person. Since the body temperature varies depending on the person, Embodiment 3 is suitable for people who need to blow air from the air conditioner.

[0083] The configuration of the air conditioner according to Embodiment 3 will be described. In Embodiment 3, detailed descriptions of the same structures as Embodiments 1 and 2 are omitted, and points different from Embodiments 1 and 2 are described in detail.

[0084] Figure 13 It is a plan view when the indoor unit of the air conditioner in Embodiment 3 of thi...

Abstract

This indoor unit for an air conditioner has: an air-blowing means for sending out air, which has undergone heat-exchange with a refrigerant, from an outlet to a space to be air-conditioned; a verticalairflow direction adjustment part that adjusts the vertical angle of the blowing direction of air sent out from the outlet; a horizontal airflow direction adjustment part that adjusts the horizontalangle of the blowing direction of air sent out from the outlet; and a control unit that controls the angles of the vertical airflow direction adjustment part and the horizontal airflow direction adjustment part. The space to be air-conditioned is divided into a plurality of areas, and the control unit controls the vertical airflow direction adjustment part and the horizontal airflow direction adjustment part to continuously change the vertical and horizontal angles, such that the air blowing direction is switched for each of the plurality of areas.

Description

technical field [0001] The present invention relates to an indoor unit of an air conditioner provided with a structure for changing the direction in which air is blown into a space to be air-conditioned. Background technique [0002] As the indoor unit of the conventional air conditioner, it is known to have a suction port provided in the central part of the lower surface side of the casing, and four air outlets provided in a manner surrounding the suction port, and to exchange heat with the air outlet. An indoor unit that sends air into the room from four outlets (see Patent Document 1). The air conditioner disclosed in Patent Document 1 includes an infrared sensor for detecting body temperature, and a first damper and a second damper respectively provided at four air outlets. The first damper changes the left-right direction of the air blown out from the outlet. The second damper changes the longitudinal direction of the air blown out from the outlet. [0003] The air c...
