Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to prevention of dew condensation on a resin-made air outlet wind direction plate 1 of an air conditioner.

[0002]

[Prior art]

 FIG. 7 is a vertical side view of a wall-mounted air conditioner. In this air conditioner, air is sucked in from an upper suction port 4 and cooled by a heat exchange air blower 5, then passed through a blower 6 and blown out from a lower air outlet 7. It is designed to blow out cold air. The air outlet 7 is provided with a plurality of wind direction plates 1 for controlling the blowing direction of the wind. FIG. 5 and FIG. 6 are a vertical sectional side view and an enlarged cross-sectional view showing the outlet wind direction plate 1 of this air conditioner. In this figure, 1 is an outlet wind direction plate, and a fiber 3 having a thickness of about 0.1 mm and hair length of 0.8 mm is planted by flocking on the back side of each outlet port wind direction plate 1. .

Next, the necessity of flocking the fibers 3 in the air outlet wind direction plate will be described. During the cooling operation of the air conditioner, the air blown out from the air outlet 7 cools the air outlet wind direction plate 1, and the humid air in the vicinity is condensed on the air direction vane 1 to form water droplets. If the air conditioner is operated in this state, water droplets will be scattered and the room will be polluted. Therefore, the above-described fiber 3 is previously subjected to a hydrophilic treatment, and the fiber 3 is planted on the back surface of the wind direction plate 1, so that the fiber 3 absorbs water droplets and prevents the water droplets from being scattered from the outlet 7. ing.

[0004]

[Issues to be solved by the device]

 Since the conventional air outlet wind direction plate 1 is configured as described above, there is a problem that it is necessary to further implant the fibers 3 after the resin forming process of the wind direction plate 1, which causes an increase in cost. .

[0005]

[Means for Solving the Problems]

 The present invention has been made in order to solve the above-mentioned problems, and instead of the conventional flocking of fibers 3, the cost is improved by in-molding the water absorbing sheet 2 on the back surface of the outlet wind direction plate 1. It is intended to provide an outlet wind direction plate 1 having a water absorption function without increasing the number of water. That is, as shown in FIG. 1, the resin air outlet wind direction plate 1 of the present invention has a water absorbent film 2a, an adhesive layer 2b, and a base on the back surface of the air conditioner outlet air direction plate 1 formed of a resin material. The water absorbing sheet 2 including the layer 2c is subjected to in-mold forming. Further, the water retention property can also be enhanced by providing fine crevices 2d on the surface of the water-absorbent film 2a, or by adhering the adhesive layer 2b in the form of dots or grids instead of the entire surface. Further, by making the material of the base layer 2c the same as the material of the outlet air flow direction plate 1, reliable in-mold molding is performed.

[0006]

[Action]

 According to the present invention, since the water-absorbent film 2a having excellent water-absorbing property is integrally formed on the back surface of the outlet wind direction plate 1 by in-mold processing, the same effect as that of the conventional flocking can be obtained. Further, when the surface of the water-absorbent film 2a is provided with fine crevices 2d, and when the adhesive layer 2b is adhered not by the whole surface but by the point adhesive 2e or the lattice-like adhesive, the water retaining function of the water-absorbent film 2a is improved. To do. Further, by making the material of the base layer 2c and the material of the wind direction plate 1 the same, the moldability can be improved.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. 1 and 2 are a vertical side view and an enlarged cross-sectional side view showing an embodiment of the wind direction plate 1 according to the present invention, and FIGS. 3 and 4 show a water absorbing sheet installed on the lower surface of the outlet air direction plate. It is a partial expanded transverse cross-sectional view of the state where it was molded. The outlet airflow direction vane 1 of the present invention is molded from a resin material made of ABS, and a water-absorbent film layer 2a is integrated on the back surface of the outlet airflow direction vane 1 by in-mold molding as shown in FIG. The water-absorbent film layer 2a has a thickness of 100 to 200 μm and a water absorption rate of about 30 times its volume. The water-absorbent film 2a is integrally provided on the base layer 2c via the adhesive layer 2b. A part of the water absorbent sheet 2 is formed.

If the surface of the water-absorbent film 2a is finely textured (not shown) in advance, the surface area is increased and the water retention function can be further improved. Further, if the adhesive layer 2b is not adhered over the entire surface but is adhered in a point adhesive manner 2e or in a lattice shape as shown in FIG. 4, a gap is formed between the adhesive layer 2b and the base layer 2c, so that water retention can be further improved. . Furthermore, by using the same material for the base layer 2c and the material for the outlet airflow direction vane 1, it is possible to improve the moldability during in-mold molding.

The water-absorbent sheet 2 of the outlet wind direction plate 1 of the present invention is mounted on a winding device (not shown) of an in-mold molding machine, and the water-absorbent sheet 2 is fed by a predetermined amount. After that, it is sandwiched between molds and integrated with the wind direction plate 1 by injection molding, and after molding, the part in-molded by the mold is cut into a long and narrow shape, and the remaining part is wound up sequentially. Has become.

[0010]

[Effect of device]

 As described above, according to the present invention, a water-absorbent film is in-molded on the back surface of the outlet wind direction plate, and the water absorption function can be added to the wind direction plate only by this molding process. Compared with the flocking process, the process can be shortened significantly and the cost can be greatly reduced. Further, the water-absorbing film 2a is preliminarily provided with fine crevices 2d, and the adhesive layer 2b is adhered not by the whole surface but by the point adhesive 2e or in the form of a lattice, thereby improving the water retaining function of the air outlet direction vane 1. be able to. Further, when the material of the base layer 2c and the material of the resin layer 1a are the same, the moldability can be greatly improved.
