In the drawings, the same reference numerals indicate the same or corresponding parts.

Next, the operation of the conventional device will be described with reference to FIGS. 3 to 6 focusing on the water splash prevention operation.

In FIG. 3 to FIG. 6, when the main body 1 is cooled and operated in the air passage by the refrigerant circuit centering on the compressor 4, the indoor fan 2, the outdoor fan 3, etc., condensed water is generated in the evaporator 5. This condensed water is stored in the water receiving portion 22 of the base 21 (Fig. 6). In FIG. 6, the condensed water accumulated in the water receiving portion 22 is driven by a motor 17 and rotates at a high speed.
It is picked up in the upward direction a and is applied to the condenser 6. With this condensed water, the latent heat of vaporization of the condenser 6 can be removed to improve the heat exchange efficiency.

In this case, a large water drop hits the condenser 6, and a splashed water drop is prevented by the water splash prevention plate 19 from jumping out to the outside of the room, and a small water drop is slanted on the louver 23 of the rear grille 11 to the outside of the room. It prevents it from jumping out.

However, since the water splash prevention plate 19 is located at the lower portion of the outdoor suction port 14, there is a risk that water droplets may fly out of the room from a portion other than the water splash prevention plate 19. In order to prevent this, the louver 23 is formed obliquely, and as a result, the noise level becomes high in order to secure the same cooling air volume.

[Problems to be solved by the invention]

As described above, in the conventional example, when the louver is formed obliquely to prevent condensed water droplets from splashing out of the room from the portion other than the water splash prevention plate, there is a problem that the noise level becomes high. .

This invention was made in order to solve the above problems, and to prevent the splash of water droplets outside the room, while maintaining the ability to ensure a sufficient air volume, to keep the noise level low. With the goal.

[Means for solving problems]

Therefore, in this invention, in the drain device of the cooler having the splashing means for splashing the condensed water to the condenser and the splash prevention plate, the splash preventing plate is disposed inside the condenser, and The means is disposed between the condenser and the water splash prevention plate, the water splash prevention plate is inclined with respect to the condenser so that the upper portion is narrowed, and a gap is provided at the upper end thereof. It is an attempt to achieve the purpose.

[Action]

The water splash prevention plate in this invention is disposed inside the condenser, and is inclined so that the upper part of the condenser is narrower,
By providing the gap at the upper end portion, water can be sufficiently scattered to the condenser, and the water droplets can be prevented from splashing out of the room.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a lower horizontal cross-sectional view of an air conditioner which is an embodiment of the cooling device of the present invention, and FIG. 2 is a vertical cross-sectional view showing a water splash prevention device of this embodiment, in which 19a is a condenser. The condenser 6 is disposed inside the condenser 6
The water splash prevention plate that is inclined so that the upper part becomes narrower and has a gap c with the condenser 6 at its upper end, 16a is the condenser 6
On the inner side, a rotating disk as a scattering means disposed between the condenser 6 and the water splash prevention plate 19a, c is the water splash prevention plate 1
A gap with the condenser 6 at the upper end of 9a, A is a gap at a position farther from the outdoor outlet 15 of the gap c, B is a gap formed at a position closer to the outdoor outlet 15 of the gap c than the gap A, The louver 23 (not shown) arranged on the rear grille 11 is not slanted as in the conventional example, is straight, does not cause a reduction in the air volume, and is configured not to generate noise. There is.

In the figure, the same or corresponding components as in the above-mentioned conventional example are represented by the same reference numerals, and the duplicated description will be omitted.

In the drawings, the same reference numerals indicate the same or corresponding parts.

Next, the operation of this embodiment will be described with reference to FIGS. 1 and 2 focusing on the water splash prevention operation.

In FIG. 1 and FIG. 2, the main body 1 is composed of a refrigerant circuit constituted by a compressor 4, an evaporator 5, a condenser 6 and piping (not shown), and an air passage formed by an indoor fan 2, an outdoor fan 3 and the like. When the cooling operation is performed, condensed water is generated in the evaporator 5. This condensed water is guided to the water receiving portion 22 of the base 21 and stored therein (FIG. 2). In FIG. 2, the condensed water stored in the water receiving portion 22 is driven upward by the rotating disk 16 which is driven by the motor 17 and rotates at a high speed, and is picked up by the condenser 6 to remove the latent heat of vaporization and remove heat of heat exchange efficiency. Raise.

The above operation is the same as that of the conventional example.

In this embodiment, as described above, the water splash prevention plate 19a
Is arranged inside the condenser 6, the rotary disc 16a is arranged inside the condenser 6 and between the condenser 6 and the water splash prevention plate 19a, and the water splash prevention plate 19a is attached to the condenser 6. On the other hand, the upper part is inclined so as to be narrow, and a gap c is provided between the condenser 6 and the condenser 6 at the upper end thereof, and the gap c at a position closer to the outdoor air outlet 15 is smaller than the gap A at a far position. Therefore, the large water droplets repelled by the rotating disc 16a hit the condenser 6, and the small water droplets pass through the gap c at the upper end portion and reach the condenser 6 above and improve the heat exchange efficiency. In addition, because of the position and shape of the water splash prevention plate 19a, water droplets do not directly jump out of the room as in the conventional example, and in particular, as described above, the gap B of the gap c is set to be smaller than the gap A. The water droplets will not be entrained by the air blown by the outdoor fan 3 from the outdoor air outlet 15 and will not splash outside.

As described above, according to the present invention, the raised condensate is efficiently applied to the condenser 6, water splashes to the outside are prevented, and the performance is improved. Further, since the louver 23 does not need to be inclined to prevent water splashing, it does not generate noise, the device can be manufactured at low cost, and a highly accurate device can be obtained.

In addition, in this embodiment, the case where the air conditioner is used for preventing the water splash in the drain treatment has been described, but it can also be used for other cooling machines such as a refrigerating machine and a cooling plant.

[Effect of device]

As described above, according to the present invention, in the water splash prevention device of the air conditioner having the splash means for splashing the condensed water to the condenser and the water splash prevention plate, the water splash prevention plate is located inside the condenser. The water splash prevention plate is disposed between the condenser and the water splash prevention plate, the water splash prevention plate is inclined at an upper portion with respect to the condenser, and a gap is formed at an upper end portion thereof. The provision of such an effect has an effect that the noise level can be suppressed to a low level while preventing the water droplets from splashing out of the room and maintaining the performance of ensuring a sufficient air volume.
