Abstract

PROBLEM TO BE SOLVED: To provide at low cost a horizontal vane for an air conditioner which can prevent condensate from dropping down and is good in its cleanliness. SOLUTION: A plurality of grooves 5 are formed longitudinally on one surface 2a 2a and a back surface of a main body 2 so that condensate is held in the respective grooves 5. The directions of the grooves 5 intersect the flowing direction of air, water droplets held in the grooves 5 do not drop owing to wind pressure. The grooves 5 are only formed on the surface 2a and the back surface of the main body 2 and hair is not planted thereon, so that the cost of a horizontal vane 1 can be lowered. Further, rubbish or dust hardly sticks to the surface 2a. Even if it sticks to the surface 2a, it can be washed simply by water or the like, hence, the cleanliness of the horizontal vane 1 can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a horizontal blade of an air conditioner.

[0002]

2. Description of the Related Art In a cooling operation, horizontal blades for changing the blowing direction of air blown from an air conditioner often cause dew condensation due to entrainment of warm air. In particular, in the case of a horizontal blade used for an air conditioner of a type mounted on a ceiling surface, as shown in FIG.
2, it may flow down and eventually drop. Therefore, in the conventional horizontal blade, flocking is performed by applying an adhesive containing short resin fibers to the blade surface, and dew water is held and held between the short fibers to prevent dripping.

[0003]

However, the above-mentioned horizontal blade of the conventional air conditioner requires an extra step of applying an adhesive containing short resin fibers to the blade surface, thus increasing the cost. There is a problem of inviting. In addition, since short fibers to be planted are made of resin, static electricity is liable to be charged easily, and there is a problem that dust adheres to the short fibers and is clogged between the short fibers, thereby deteriorating the aesthetic appearance and a problem of being difficult to remove even after washing.

It is an object of the present invention to provide a low-cost horizontal blade of an air conditioner which can prevent the condensation water from dripping and has good cleanliness.

[0005]

Means for Solving the Problems To achieve the above object, the horizontal blade of the air conditioner according to the first aspect of the present invention is characterized in that a concave portion for holding dew water is provided in a main body.

According to the above construction, the dew water generated on the surface of the main body of the horizontal blade during cooling is held in the recess by the surface tension and does not drip. Thus, with the simple and low-cost structure of forming the concave portion, dripping of the dew condensation water is prevented. Furthermore, since there is no flocking on the surface of the horizontal blade as in the conventional case where there is only a concave portion, dirt and dust are hardly attached, and even if attached, it can be easily washed. Thus, the cleanliness of the horizontal blade is improved.

According to a second aspect of the present invention, in the horizontal blade of the air conditioner according to the first aspect of the present invention, the recess extends in a direction intersecting a flow direction of the air flowing along the surface of the main body. It is characterized by existing grooves.

[0008] According to the above configuration, the dew water held in the groove is less likely to be subjected to wind pressure because the groove intersects the flow direction of the air, and the retention of the dew water is enhanced. if,
Assuming that the groove extends in the direction of air flow, the water flow in the groove is carried and dropped by the flow of air.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. FIG. 1 shows a horizontal blade of the air conditioner of the present embodiment. FIG. 1A is a perspective view of a main part, and FIG. 1B is a sectional view taken along the line AA in FIG. 1A. The main body 2 of the horizontal blade 1 has a surface 2a curved in the narrow width direction. Also, support plates 3 (only one is visible in the figure) are attached to both ends of the main body 2, and one end of the rotating shaft 4 is attached to each support plate 3.
Then, the support plate 3 and the main body 2 integrally rotate about the rotation shaft 4 in the direction of arrow B to change the direction of the air blown out along the surface 2a.

On the one surface 2a of the main body 2 and on the back surface thereof, a plurality of grooves 5 having a rectangular cross section are formed in parallel to extend in the longitudinal direction. Then, the dew water is held in each groove 5 by the surface tension so as not to drop. In this case, since the direction of the groove 5 is the longitudinal direction (that is, the extending direction of the rotating shaft 4), it intersects with the air flow direction,
In particular, the directions are orthogonal. Therefore, the dew water held in the groove 5 does not fall by wind pressure.

The surface 2a of the main body 2 is not provided with a flute just like the conventional horizontal blade because of the presence of the groove 5. Therefore, dirt and dust are unlikely to adhere to the surface 2a, and even if they do, they can be easily washed away by washing with water or the like. Therefore, the cleanliness of the horizontal blade 1 can be improved. Further, extra steps such as flocking can be reduced, and the cost of the horizontal blade 1 can be reduced. Further, since it is not necessary to perform post-processing such as flocking on the main body 2, the degree of freedom in design is improved. The width, interval, and depth of the groove 5 need to be set to optimal values so that the retained dew condensation water does not drop in consideration of the inclination angle of the main body 2 and its fluctuation width and wind speed. is there. In the present embodiment, the width and the interval are set to about 1 mm, and the depth is set to 0.5 mm to 1 mm.

FIG. 2 shows a horizontal blade of another air conditioner. 2A is a perspective view of a main part, and FIG. 2B is a cross-sectional view taken along the line CC in FIG. 2A. Main body 1 of horizontal blade 11
2 has a surface 12a curved in the narrow direction,
A dimple 15 is formed on one surface 2a of the second and the back surface thereof. Then, the dew water is dispersed and held in each dimple 15 by its surface tension. In this way, by dispersing and holding the dew water little by little, it is possible to prevent individual water droplets from sticking together and growing into large water droplets, leading to dropping. In addition, since the surface 12a of the main body 12 has only the dimples 15 and is not planted like a conventional horizontal blade, dirt and dust hardly adhere thereto. Further, even if dirt or dust adheres to the surface 12a, it can be easily washed away with water or the like, and the cleanliness of the horizontal blade 11 can be improved. In addition, the surface of the main body 12 has a simple structure without being planted with hair, so that the cost can be reduced. Further, since there is no need for post-processing, the degree of freedom in design is improved. In addition, 13 is a support plate, and 14 is a rotating shaft.

In FIGS. 1 and 2, the grooves 5 or dimples 15 are formed over the entire surfaces 2a, 12a of the main bodies 2, 12, but this is not absolutely necessary. It may be formed only on portions of the surfaces 2a and 12a where the dew condensation water easily falls.

[0014]

As is clear from the above description, the horizontal blade of the air conditioner according to the first aspect of the present invention has a concave portion for retaining dew water on the main body. The dew water is held in the recess and does not drip.
Therefore, according to the present invention, the surface of the horizontal blade has only a concave portion and is not planted like a conventional horizontal blade, so that dirt and dust hardly adhere thereto. Even if it adheres, it can be easily washed. Therefore, the cleanliness of the horizontal blade can be improved. In addition, since the horizontal blade has a simple structure having only a concave portion, the cost can be reduced.

[0015] Further, the concave portion of the invention according to claim 2 is:
Since the groove extends in a direction intersecting with the flow direction of the air flowing along the surface of the main body, the dew water held in the groove is hardly subjected to wind pressure. Therefore, the retention of dew water can be improved.
