Abstract

PROBLEM TO BE SOLVED: To provide a comfortable air conditioning by solving a nonuniform flow of air from blow-off holes due to the dynamic pressure influence of the air flow in a blow-off device for air conditioners. SOLUTION: The blow-off device for air conditioners comprises a rotatably mounted air blow-off duct 4 and long and oblong blow-off holes 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i erected in shape like a mountain in the circumferential direction on the side surface of the air blow-off duct 4. In the constitution, the areas of the blow-off holes 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i are decreased toward the top, so that higher resistance is applied on the air flow at the upper part for suppressing the air flow from the upper parts and thus a uniform flow of air is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower for an air conditioner used for refrigeration and air conditioning.

[0002]

2. Description of the Related Art Conventionally, a blowing device for an air conditioner has been disclosed in Japanese Patent Laid-Open No.
One described in Japanese Patent No. 35414 is known.

FIG. 2 shows the structure of a conventional air blower for an air conditioner. It has a structure in which a cylindrical blow-out duct 4 having an air blow-out port 3 in a part of its periphery is rotatably and rotatably incorporated in an opening 2 of a blow duct 1.

In this structure, the wind sent from the blow duct 1 is guided to the blow duct 4 and blown out from the air blow port 3. At this time, since the blow-out duct 4 has a structure in which the blow-out duct 4 can be moved in and out and can be rotated,
The direction and amount of the blown wind can be freely set.

[0005]

In this air conditioner blower, the air flowing from the opening 2 of the blower duct 1 to the lower part of the cylindrical air blower duct 4 is affected by the dynamic pressure, and the air blower 4 Almost flows out from the upper part of the outlet 3 and hardly flows from the lower part of the outlet 3, so that an even flow cannot be obtained.
Therefore, a uniform wind flow from the outlet 3 is required.

An object of the present invention is to provide a uniform air flow from the outlet 3 and provide comfortable air conditioning.

[0007]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention comprises an air outlet duct rotatably mounted and a plurality of vertically elongated rectangular shapes in the circumferential direction on the side surface of the air outlet duct. It is provided with an outlet that is connected to the Yamagata.

[0008] Thus, a uniform wind flow from the outlet is obtained.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides an air outlet duct rotatably mounted and a plurality of vertically elongated rectangular outlets in the circumferential direction of the side surface of the air outlet duct. Because the outlet has a vertically long rectangular shape and is connected to the mountain shape, the outlet is narrower toward the upper part, suppressing the flow of wind from the upper part, and It has the effect of gaining.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG.

FIG. 1 shows a blower for an air conditioner according to an embodiment of the present invention. In FIG. 1, an air blowing duct 4 has a cylindrical shape, and is built in the opening 2 of the blowing duct 1 so as to be able to protrude and retract and to be rotatable. On the side surface of the air outlet duct 4, vertically long rectangular outlets 3a, 3
The configuration is such that b, 3c, 3d, 3e, 3f, 3g, 3h, 3i are formed in a chevron in the circumferential direction of the air blowing duct 4.

[0012] The air flow of the air-conditioning apparatus having the above configuration will be described below. The wind flowing into the lower part of the cylindrical air blow-out duct 4 from the opening 2 of the blower duct 1 is blown out by the blow-out ports 3a, 3d under the influence of the dynamic pressure.
b, 3c, 3d, 3e, 3f, 3g, 3h, 3i are concentrated at the upper part, but the outlets 3a, 3b, 3c, 3d, 3e,
Since 3f, 3g, 3h and 3i are arranged in a chevron in the circumferential direction of the air blow-out duct 4, the blow-out port 3 is closer to the top.
a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i
Is reduced, the flow of wind from above is suppressed, and a uniform wind flow can be obtained.

The outlets 3a, 3b, 3c, 3d,
Since 3e, 3f, 3g, 3h, 3i have a vertically long rectangular shape, when adjusting the air volume by taking in and out the blow-out duct 4, the blow-out openings 3a, 3b, 3c, 3d, 3
e, 3f, 3g, 3h, and 3i can be smoothly performed without concern.

The outlets 3a, 3b, 3c, 3d,
Since 3e, 3f, 3g, 3h, 3i have a vertically long rectangular shape, large objects are blown out from the outlets 3a, 3b, 3b.
3c, 3d, 3e, 3f, 3g, 3h, 3i can be prevented from getting inside.

[0015]

As described above, according to the present invention, there is provided an air outlet duct rotatably mounted, and a plurality of vertically-elongated air outlets having a plurality of elongated rectangular shapes in the circumferential direction of the side surface of the air outlet duct. Since the air-conditioning blower is provided with a port, by reducing the area of the blow-out port toward the upper part, the advantageous effect of suppressing the flow of air from the upper part and obtaining a uniform flow of air can be obtained. In addition, since the outlet has a vertically long rectangular shape, it is possible to smoothly adjust the air volume by taking in and out the outlet duct, and furthermore, has an advantageous effect of preventing a large object from entering through the outlet. Is obtained.
