Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an air outlet of an indoor unit of an air conditioner.

[0002]

2. Description of the Related Art A side view of the inside of an indoor unit of an air conditioner is shown in FIG.
And a front cover 23 that is detachably attached to the main body 22.
And a front panel 24 attached to the front cover 23 so as to be openable and closable. Upper part of chassis 21 (front cover
The upper part of 23 and the front panel 24) are provided with an intake port 25 for taking in indoor air, and the lower part of the front face is provided with an outlet port 26 for sending out heat-exchanged air into the room. An air filter 28, an indoor heat exchanger 29 that is bent back and forth in a plurality, and a blower (cross flow fan) 30 are arranged in an air passage 27 that connects the suction port 25 and the air outlet 26, and indoor heat exchange is performed. The air that has undergone heat exchange by the device 29 is sent to the outlet 26 by the blower 30, and the wind direction into the room is adjusted vertically and horizontally by the vertical airflow direction plate 31 and the left and right airflow direction plate 32 provided at the air outlet port 26. For example, during cooling operation, the vertical wind direction plate 31 is controlled in a substantially horizontal direction to reduce the fall of the cool air, and during heating operation, the vertical wind direction plate 31 is arranged as shown in FIG.
The air outlet 26 is directed downward by controlling in a substantially vertical direction as shown in (1) to accelerate the descent of warm air.

[0003]

However, when the vertical wind direction plate 31 is vertically rotated as shown in FIG. 3, the flow of the wind becomes unnatural, so that turbulent flow easily occurs near the outlet 26, which causes noise. May be. In addition, before and after the outlet 26 A
Becomes smaller, it becomes difficult to operate the left and right wind direction plates 32 in an indoor unit in which the left and right wind direction plates 32 are of a manual type. Furthermore,
Even if the left / right airflow direction plate 32 is adjusted obliquely, the wind passing through the left / right airflow direction plate 32 is forcibly turned downward by the up / down airflow direction plate 31, and thus there is a problem that it does not proceed in the intended direction. Therefore, it is an object of the present invention to provide an indoor unit of an air conditioner that solves these problems.

[0004]

The present invention has been made to solve the above problems, and an air filter is provided in an air passage connecting an intake port at the upper part of a housing and an outlet port at the lower part of the same housing. And an indoor heat exchanger, and a blower that sends out the air that has undergone heat exchange by the indoor heat exchanger to the air outlet,
In a structure in which the wind direction into a room is adjusted by a vertical wind direction plate and a horizontal wind direction plate provided at the air outlet, a movable diffuser is provided at the air outlet so that a lower portion of the air outlet rotates forward. At the same time, the left and right wind direction plates are provided on the movable diffuser.

[0005]

With the above construction, when the vertical airflow direction plate rotates vertically during the heating operation, the movable diffuser can be rotated forward to widen the air outlet, thereby improving the airflow. When the movable diffuser rotates forward, the left and right airflow direction vanes also rotate in the same direction and approach the air outlet, so that the left and right airflow direction vanes can be operated easily, and the wind from the air outlet can be directed in the intended direction. Can be turned to.

[0006]

Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view showing the appearance of an indoor unit. Reference numeral 1 denotes a main body 2, a front cover 3 detachably attached to the main body 2, and a front panel 4 attached to the front of the front cover 3 so as to be openable and closable. It is a housing consisting of. A suction port 5 for indoor air is formed in the upper part and the front part of the housing 1, and an air outlet 6 is formed in the lower part in the front part. The inside of the center of the housing 1 is viewed from the side as shown in FIG. 2, and a detachable air filter 8 is provided in the air passage 7 between the suction port 5 and the air outlet 6.
An indoor heat exchanger 9 that is divided into a plurality of parts and bent back and forth, and a blower (cross flow fan) 10 for sending out the air that has been heat-exchanged by the indoor heat exchanger 9 to the air outlet 6 are arranged. The outlet 6 is provided with a vertical airflow direction plate 11 for vertically adjusting the blowing of air into the room. Further, a movable diffuser 13 that has a drive unit 12 and rotates the lower portion of the outlet 6 forward is provided at the lower portion of the outlet 6, and the movable diffuser 13 adjusts the blowing air into the room to the left and right. Left and right wind direction plate 14
Is installed.

By the way, the positions of the vertical wind direction plate 11, the movable diffuser 13 and the left and right wind direction plate 14 change according to the operation mode. For example, during cooling operation, the vertical wind direction plate 11 is rotated so as to be substantially horizontal. On the other hand, the movable diffuser 13 and the left and right wind direction plates 14 are held at the positions shown by the broken lines. In such a state, the cold air from the air outlet 6 can be sent to a long distance without being lowered. Also,
In the heating operation, the vertical wind direction plate 11 is rotated in a substantially vertical direction as shown in the drawing to close the front of the air outlet 6, while the movable diffuser 13 and the left and right wind direction plates 14 are rotated to the positions shown by the solid line to blow. The front and rear of the outlet 6 is widened from A to B, and the left and right wind direction plates 14 are brought close to the outlet 6 to improve the flow of warm air into the room. With such a configuration, turbulent flow near the outlet 6 can be eliminated, and the left and right wind direction plates 14 can be easily operated.

[0008]

According to the indoor unit as described above,
There is no possibility of turbulence occurring because the air flow at the air outlet is good in heating operation, and turbulent flow does not occur in heating operation, quieter operation is possible and the amount of air blown to the floor surface is increased and it is comfortable. The property is improved. In addition, the left and right wind direction plates can be easily operated, which is convenient.
