Description

[Detailed description of the invention] Industrial application field The present invention is a water splash prevention device for an air conditioner that cools a room, and has a function of evaporating condensed water generated in the evaporator by passing it through the condenser. It is related to.

BACKGROUND ART In recent years, from the viewpoint of energy saving, efforts have been made to improve the performance of air conditioners by passing condensed water through a condenser.

The conventional structure for applying condensed water to a condenser will be described below with reference to the drawings.

Conventionally, this type of air conditioner was manufactured in
As shown in JP-A-22017 and JP-A-57-104065, the structure was as shown in FIGS. 7 to 9.

That is, as shown in FIG. 7, the condenser 2 is protected by a wire mesh 1 shown in FIG. 8.
Further, in FIG. 9, 3 is a rotating disk that scatters condensed water and applies it to the condenser 2, and 4 is the rotating disk 3.
This is the motor that drives the. Then, the rotary disk 3 is rotated at a high speed, and the water droplets from which the condensed water is scattered are attached to the condenser 2, and the heat exchange efficiency of the condenser 2 is improved by the latent heat of evaporation.

Problems to be Solved by the Invention However, in the above configuration, because the wire mesh 1 is coarse, water droplets that hit the condenser 2 bounce off and fly out of the air conditioner body, causing damage to passersby. This problem occurs, and if a large space is provided for the water droplets to scatter in order to prevent this problem, the space required for the air conditioner itself becomes large.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a water splash prevention plate that is integrated with the synthetic resin intake grill and is located near the rotating disk. A side edge is provided that extends in the width direction of the air conditioner in the vertical direction, and the lower part of this side edge extends longer than the upper part.

Effects The present invention has the above-described structure, so that large water droplets directly or splashing water droplets that hit the condenser are prevented from flying out of the air conditioner main body by the water splash prevention plate, and The lower side edge of the prevention plate prevents large water droplets from flying out, and the upper side edge prevents small water droplets from flying out.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 6 of the accompanying drawings.

3 shows an upper cross section of the air conditioner main body 5, and FIG. 4 shows a lower cross section of the air conditioner main body 5.

In the figure, reference numeral 6 denotes vertical louvers A, and a plurality of louvers A are provided to constitute an intake grille 7. Reference numeral 8 denotes vertical louvers B, and a plurality of louvers B are provided to constitute the intake grille 7. 9 is a water splash prevention plate provided near the rotating disk 3, 10 is a blowout grill, and 11 is a frame. The louver A6, the louver B8, the water splash prevention plate 9, the blowout grille 10, and the frame 11 are integrally molded from a synthetic resin material to constitute a rear grille 12. 13 is a condenser, 14 is an outdoor cross-flow fan, 15 is an indoor cross-flow fan, 16 is an air guide A that partitions the indoor side and the outdoor side on the upper side of the air conditioner main body 5, and 17 is the air conditioner main body 5
18 is an evaporator, 19 is a stabilizer on the indoor side, 20 is a stabilizer on the outdoor side, 21 is a front grill that also serves as an outer box and is equipped with an intake grill.
22 is a control unit, 23 is a compressor, 24 is a soundproof plate, 2
5 is a motor that drives the rotating disk 3. In FIG. 5, 26 is a substrate which serves as the base of each part.
27 is a connecting rib A that reinforces the louver A6, and 28 is a connecting rib B that reinforces the louver B8. In FIG. 6, 29 is the evaporator 18
This is a water tray that receives condensed water generated in the process. Reference numeral 30 denotes a shaft of a motor 25, which transmits driving force to the rotating disk 3 by the motor 25 provided in the control unit 22, passes through the air guider B, passes through the lower part of the condenser 13, and is transmitted from the windward side of the condenser 13. It is configured to scatter condensed water.

FIG. 1 is an enlarged plan view of the main part of the vicinity of the water splash prevention plate 9 seen from the condenser 13, and FIG. 2 is an enlarged sectional view of the M section in FIG. 4.

In the same figure, 9b1, 9b2, 9c1, 9c
2 are the side edges of the water splash prevention plate 9, and the lengths of these side edges are such that the side edge 9b1 and the side edge 9c1 are the side edges of the condenser 1.
3, the ribs 31 abut against the condenser 13 to maintain a gap. The lengths of the side edges 9b2 and 9c2 are shorter than those of the side edges 9b1 and 9c1.
Therefore, the gap with the condenser 13 is increased.

The structure of the rear grill of the air conditioner configured as above is shown in Figures 1, 2, and 3 below.
The operation will be explained using FIGS. 4 and 6.

Condensed water generated in the evaporator 18 is received by a water tray 29, guided to the condenser 13, and collected on the substrate 26. The condensed water that has accumulated on the substrate 26 is scattered upward (in the direction of arrow a in FIG. 6) by the rotating disk 3 that rotates at high speed, is applied to the condenser 13, and evaporates. Ubai condenser 13
Increase heat exchange efficiency.

Here, large water droplets are prevented from splashing out to the outside of the room by the water splash prevention plate 9. Further, relatively large water droplets a1 are scattered near the lower rotary disk 3 of the air conditioner main body 5, and the side edges 9b1 and 9c1 prevent the water droplets from flying out to the outside of the room. Also, large water droplets collide with the condenser 13 and are reflected.
2 is blocked by the side edge 9b1 and the side edge 9c1. The small water droplets are scattered upwards and form the side edge 9b.
2. The side edge 9c2 prevents water droplets from splashing out to the outside.

As described above, according to this embodiment, the water splash prevention plate 9 prevents water droplets scattered by the rotating disk 3 from scattering to the outdoor side. Furthermore, since the scattered water droplets are effectively applied to the condenser and evaporated without being discharged to the outside, heat exchange efficiency can be increased.

Effects of the invention As described above, the present invention provides a water splash prevention plate on the intake grille, and provides side edges extending in the width direction of the air conditioner on both sides of the water splash prevention plate in the vertical direction. By extending the lower part longer than the upper part, it is possible to prevent water from splashing to the outside of the room, and it is possible to eliminate the problem of water splashing onto passersby. Furthermore, it is possible to improve the design of the back side of the air conditioner body, and it is also highly effective in protecting the condenser.
