Description

Air conditioner
Technical Field
The present invention relates to an air conditioner.
Background
An air conditioner is generally known in which an air supply circuit is formed in a main body casing having an air inlet and an air outlet, and a fan is provided in the air supply circuit. In this conventional air conditioner, a heat exchanger is disposed in the vicinity of the upstream side of the fan, and the air sucked from the suction port by the rotation of the fan is heat-exchanged by the heat exchanger and then blown out from the discharge port. In addition, the conventional air conditioner includes a rear guide and a stabilizer in order to control the flow of air generated by the rotation of the fan. In addition, as the flow of air generated by the rotation of the fan, there are: a flow (main flow) blown out from the outlet by the fan; and a flow (vortex) generated between the fan and the stabilizer and circulating in a vortex shape at the front end of the stabilizer.
Here, an air conditioner 1 disclosed in patent document 1 will be described with reference to fig. 4 as an example of a conventional indoor unit. The air conditioner 1 includes: a suction port 3 provided on the lower surface of the main body casing 2; an air outlet 4 provided in the front surface of the main body casing 2; an air passage 5 connecting the suction port 3 and the discharge port 4; a front heat exchanger 6; a rear heat exchanger 7; a fan 8 that sends out the air after heat exchange to the air outlet 4 and is positioned above the front heat exchanger 6 and the rear heat exchanger 7; a dew-water receiving pan 9 located at a lower portion of the front and rear heat exchangers 6 and 7 and receiving condensed water; and an auxiliary suction port 10 provided at a front surface or a lower surface of the front heat exchanger 6. Further, the air conditioner 1 includes: a rear guide 11 connecting an upper portion of the blower 8 and an upper portion of the outlet 4; a stabilizer 12 connecting a lower portion of the fan 8 and a lower portion of the blowout port 4; and a partition wall 13 connecting the upper end of the rear heat exchanger 7 and the rear of the suction port 3.
By the rotation of the fan 8, air is sucked in through the front heat exchanger 6 and the rear heat exchanger 7. Air flows through the fan 8 and is blown out of the main body casing 2 through the air passage 5 formed by the stabilizer 12 and the rear guide 11. At this time, the air flowing along the partition wall 13 through the suction port 3 passes through the rear heat exchanger 7 and then flows along the rear guide 11. The rear guide 11 has a substantially horizontal surface above the fan 8, a curved surface extending therefrom, and a surface facing obliquely downward at the air outlet 4. The stabilizer 12 has a surface facing obliquely downward at the outlet 4. Therefore, the direction of the blown air can be controlled to be directed obliquely downward.
However, in the air conditioner 1 of patent document 1, the direction of the blown air can be directed obliquely downward, but it is difficult to blow the blown air in the horizontal direction. Since blowing in the horizontal direction is difficult, there is a problem that controllability of an indoor airflow environment for forming an airflow of a region where no airflow is present cannot be achieved in a room.

Detailed Description
The air conditioner of the invention 1 includes: an indoor housing having a suction port and a blow-out port; an air supply loop connecting the suction inlet and the blowing outlet; the fan is arranged on the air supply loop; a wind direction plate that controls the direction of the airflow blown out from the air outlet; a rear guide having a function of guiding an airflow from the fan to the air outlet; and a stabilizer having a function of guiding the airflow from the fan to the air outlet. The air outlet is configured to blow air horizontally on the front surface of the main body case, and the suction port is located below the air outlet. The wind direction plate is formed of a surface continuous with a wall surface of the air outlet constituting the air blowing circuit. Here, "horizontal direction" means "substantially horizontal direction".
The air deflector is formed of a continuous surface continuing from the air blowing circuit at the air outlet, and thus, in the air conditioner in which the air outlet is formed in a substantially horizontal direction, the air flow can be blown out in a substantially horizontal direction from the front surface of the main body case. Further, when the air outlet is located near the ceiling of the room in which the air conditioner is installed, the ceiling airflow can be efficiently formed in the room, and a comfortable indoor airflow can be formed.
The invention of claim 2 is the air conditioner of claim 1, further comprising: a 1 st wind direction plate formed of a surface continuous to a wall surface of the stabilizer; and a 2 nd wind direction plate formed of a surface continuous with the wall surface of the rear guide.
By disposing the 1 st air direction plate between the air outlet and the air inlet located below the air outlet, it is possible to suppress a short circuit in which the air flow blown out from the air outlet directly flows into the air inlet, and it is possible to efficiently blow out the air flow from the front surface of the main body case in a substantially horizontal direction. Thereby enabling a comfortable indoor airflow.
In particular, according to claim 3 of the present invention, in the air conditioner according to claim 1 or 2, the driving shaft for driving the 2 nd louver to rotate is disposed at a position spaced apart from the end of the air outlet by a distance having a distance interval between the front end of the 2 nd louver and the driving shaft.
Accordingly, when the direction of the airflow blown out from the outlet is controlled by the rotational drive of the 2 nd louver, it is possible to alleviate the decrease in the air volume due to the decrease in the distance between the 2 nd louver and the 1 st louver. As a result, the air volume can be ensured regardless of the direction of the blowout airflow.
The 4 th invention is the air conditioner according to the 1 st or 2 nd invention, particularly, wherein a driving arm for driving the 2 nd louver is provided. The 2 nd wind direction plate rotates about a drive axis located at the front end of the drive arm.
Accordingly, when the direction of the airflow blown out from the outlet is controlled using the driving arm that drives the 2 nd louver, the interval between the 1 st louver and the 2 nd louver can be maintained at a constant value regardless of the direction of the blown-out airflow. This can alleviate the change in the air volume due to the direction of the blown air flow. As a result, the air volume can be ensured regardless of the direction of the blowout airflow.
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described below are merely examples, and the present invention is not limited to the embodiments.
(embodiment mode 1)
Fig. 1 is a sectional view showing an example of the structure of an air conditioner 100 according to the present embodiment.
An indoor unit 101 of an air conditioner 100 will be described with reference to fig. 1. Main body case 102 includes suction port 103 and discharge port 104. Inside the main body case 102, an air supply circuit 105, a fan 106, a stabilizer 107, a rear guide 108, and a heat exchanger 109 are provided. Outlet 104 is formed in a substantially horizontal direction so as to be located near the ceiling on the front surface of main body casing 102. Suction port 103 is located below discharge port 104. Further, the wind direction plate 1 includes a wind direction plate 1 formed of a continuous surface continuous to the stabilizer 107 and a wind direction plate 2 including a continuous surface continuous to the rear guide 108. Drive shaft center 120 of 2 nd air flow plate 111 is located at the end of air outlet 104 at the front end of rear guide 108.
The fan 106 blows air in a substantially tangential direction of the blade outer circumference circle, and generates a flow (main flow) blown out from the outlet 104 by the fan 106 and a swirl-like circulating flow (vortex flow) generated between the fan 106 and the stabilizer 107. Blow-out port 104 is formed so as to be sandwiched in the vertical direction by rear guide 108 and stabilizer 107, and the blow-out direction thereof is substantially horizontal. The air can be blown into the room through the suction port 103 without causing a short circuit (short circuit) by the 1 st louver 110 formed on the continuous surface with the stabilizer 107 and the 2 nd louver 111 formed on the continuous surface with the rear guide 108. Therefore, the top airflow can be efficiently formed in the room, and the comfortable indoor airflow can be formed.
Further, the driving axis center of the 1 st wind direction plate 110 is located at the front end of the stabilizer 107 at the end of the air outlet, and the driving axis center 120 of the 2 nd wind direction plate 111 is located at the front end of the rear guide 108 at the end of the air outlet. The 1 st louver 110 and the 2 nd louver 111 are rotationally driven around their respective drive axes, and control the direction of the airflow blown out from the air outlet 104.
(embodiment mode 2)
Fig. 2 is a sectional view showing an example of the structure of an air conditioner 200 according to the present embodiment. In fig. 2, the components common to embodiment 1 are denoted by common reference numerals.
As shown in fig. 2, in the indoor unit 101 of the air-conditioning apparatus 200, a drive shaft center 220 for rotationally driving the 2 nd air-directing plate 111 is provided at a position spaced apart from the end of the air outlet 104 in the air-out direction by a distance having a distance between the front end of the 2 nd air-directing plate 111 and the drive shaft center 220. When the airflow blown out from outlet 104 is blown out in the horizontal direction, 2 nd airflow plate 111 is rotationally driven to a position where the front end thereof abuts against the front end of rear guide 108. When the airflow blown out from the air outlet 104 is blown out obliquely downward by the 2 nd louver 111, the 2 nd louver 111 is rotationally driven to a position where the front end thereof faces obliquely downward. This can alleviate the decrease in the air volume caused by the decrease in the distance between the 2 nd louver 111 and the 1 st louver 110 when the 2 nd louver 111 is rotationally driven. As a result, the air volume can be ensured regardless of the direction of the blown air flow, and a comfortable indoor air flow can be formed.
(embodiment mode 3)
Fig. 3 is a sectional view showing an example of the structure of an air conditioner 300 according to the present embodiment. In fig. 3, the components common to embodiment 1 are denoted by common reference numerals.
As shown in fig. 3, in the indoor unit 101 of the air conditioner 300, the driving arms 112 support both left and right ends of the 2 nd louver 111. The drive arm 112 has a drive portion, and the 2 nd louver 111 performs horizontal movement and rotational movement in the blowing direction by the operation of the drive portion. Thus, the 2 nd louver 111 supported by the driving arm 112 performs horizontal movement and rotational movement. Further, by setting the support portion of the driving arm 112 to the 2 nd louver 111 as the driving axis 320 of the 2 nd louver 111, it is possible to perform rotation around the driving axis in addition to the movement of the driving arm 112. When the airflow blown out from air outlet 104 is blown out in the horizontal direction, 2 nd louver 111 is driven to a position that forms a continuous surface with rear guide 108. When the airflow blown out from outlet 104 is blown out obliquely downward by 2 nd louver 111, 2 nd louver 111 is driven to a position at which the front end thereof faces obliquely downward. This can alleviate the decrease in the air volume caused by the decrease in the distance between the 2 nd louver 111 and the 1 st louver 110 when the 2 nd louver 111 is rotationally driven. As a result, the air volume can be ensured regardless of the direction of the blown air flow, and a comfortable indoor air flow can be formed.
In the present embodiment, a cross-flow fan is used as the fan, but the present invention is not limited to this. A turbo fan, an axial fan, or the like may be used as the fan.
