【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 and 2 show one form of a drain water evaporation device according to the present invention, and this device is also installed in a machine room 2 disposed below a case body 1 as shown in FIG. It is installed together with the compressor 3, the condenser 4, the blower 5, and the like. Further, this drain water evaporator also includes a drain pan 6 for storing drain water and an evaporation cloth 7 provided therein as in the conventional case. Reference numeral 10 is a drain pipe that guides drain water such as defrost water generated in the cooling unit to the evaporator.

The present invention is characterized by a sprinkler for sprinkling water on the evaporation cloth 7, and in the first embodiment, as shown in FIG. 1, includes a watering tray 13 provided on the evaporation cloth 7. It is configured such that the drain water discharged from the drain pipe 10 is received by the water spray tray, and the drain water is dripped on the evaporation cloth through the water spray tray. The feature of this device is that the water spray tray 13 is made of a water-permeable material, and the water spray tray is made of cloth, preferably made of hydrophilic cloth such as evaporation cloth. Alternatively, a material made of a porous resin material or the like is used. Therefore, the drain water introduced from the drain pipe 10 into the water spray tray 13 seeps out from the contact surface between the water spray tray and the evaporation cloth.

Therefore, the drain water received in the water spray tray 13 is totally sprayed on the evaporation cloth, and is effectively evaporated by the evaporation cloth. At that time, the blower 5 passes the compressor 3 and the condenser 4 and cools them by air, and the relatively high temperature air is applied to the evaporation cloth 7, and the exhaust heat thereof is used for the evaporation of the drain water. Water that cannot be completely evaporated while flowing down the evaporation cloth is collected in the drain pan 6, and is sucked up again by the evaporation cloth due to the capillary phenomenon and evaporated. In this case, since the sprinkling tray plays a role of a filter against the drain water, the organic substances contained in the drain water do not adhere to the evaporation cloth, so that the deterioration over time is preferably prevented.

FIGS. 3 to 5 show another embodiment of the present invention. As shown in FIG. 5, the drain pan 6 and the evaporation cloth 7 provided therein are also installed in the machine room 2. including. In this embodiment, the drain water evaporation device includes a pipe 14 for sprinkling, which is installed on the evaporation cloth 7, and a pump 15 which sends the drain water in the drain pan to the pipe.

The pipe 14 is installed so that its end is closed and fits on a series of tops of the evaporation cloth 7, so that the pipe 14 has slits 16 on both sides thereof at appropriate intervals, as shown in FIG. And a notch 7a is provided in each top of the evaporation cloth, preferably in the center. Therefore, the pipe 14 is installed at the position of the slit 16 so as to fit into the notch 7a at each top of the evaporation cloth. Reference numeral 8 is a support frame for the evaporation cloth, and 17 is a connecting pipe between the pump 15 and the pipe 14.

In this configuration, the drain water flowing out from the drain pipe 10 is temporarily stored in the drain pan 6, is sent to the water spray pipe 14 via the pipe 17 by the pump 15, and is exuded from the slit 16 to the evaporation cloth 7, Water the entire evaporation cloth. The evaporation cloth receives the wind from the blower 5 to evaporate the drain water, and the water that cannot be completely evaporated is collected in the drain pan 6 and again sent to the pipe 14 by the pump. Therefore, the drain water is uniformly sprayed from the slit 16 of the pipe 14 to the evaporation cloth, and the entire evaporation cloth is used for evaporation.

6 and 7 show a third embodiment of the present invention, which is also installed in the machine room and includes a drain pan 6 and an evaporation cloth 7. In this case as well, the notch 7a is provided at each top of the evaporation cloth 7. Each notch is preferably formed in the center of the top. Further, in this device, a gutter 18 installed so as to fit into the notches 7a, a sprinkler pipe 19 arranged in the gutter, and drain water in the drain pan 6 are piped through a connection pipe 17. A pump 15 for sending to 19 is provided. The gutter 18 and the pipe 19 are each made of a water permeable material such as cloth or porous resin.

Even in this form, the drain water flowing out from the drain pipe 10 is stored in the drain pan 6 and sent to the water spray pipe 19 by the pump 15. The water in the pipe 19 flows out into the gutter 18, and then, through the contact portion between the gutter and the evaporation cloth in the cutout portion 7a, it suitably exudes to the evaporation cloth 7, and is uniformly sprayed on the entire evaporation cloth. Also in this case, the drain water is evaporated by receiving the wind from the blower 5. The drain water that has flowed down the evaporation cloth without being evaporated is again sent to the water spray pump 19 by the pump 15 and sprayed on the evaporation cloth.

8 and 9 show a fourth embodiment of the present invention, which also includes a drain pan 6 and an evaporation cloth 7, and a pipe 20 for spraying water on the evaporation cloth. Further, as shown in the figure, a pump 15 for sending the drain water in the drain pan to the pipe 20 via the connection pipe 17 is provided. Further, similarly to the above-described embodiment, notches 7a are provided at each top of the evaporation cloth 7, preferably at the center of the top, and a gutter 18 is provided at each notch. The pipe 20 is provided in the gutter.

The gutter 18 is also made of a water-permeable material, preferably the same cloth as the evaporation cloth 7 or porous resin. As shown in FIGS. 8 and 9, the pipe 20 arranged in the trough has overflow holes 20a formed on the upper side thereof at appropriate intervals, and the overflow holes may have any shape, but are generally shown. Is formed as an arc-shaped slit.

Also in this case, the drain water discharged from the drain pipe 10 is stored in the drain pan 6 and is sent to the sprinkling pipe 20 by the pump 15. From there, the drain water enters the trough 18 through the overflow hole 20a, and the evaporation cloth It oozes out from each notch 7a to the whole evaporation cloth. Therefore, the drain water is evaporated on the entire surface of the evaporation cloth.

FIG. 10 and FIG. 11 show still another embodiment of the present invention, in which the device also includes the drain pan 6 and the evaporation cloth 7, a sprinkling pipe 21 is further provided, and a connecting pipe 17 is provided by the pump 15. The drain water in the drain pan 6 is sent to the sprinkling pipe 21 via the. The end of the sprinkling pipe 21 is closed by a plug 22 or the like.

The pipe 21 is formed of a water-permeable material, for example, the same cloth as the evaporation cloth or a material such as porous resin. As shown in FIG. 11, the lower portion 21a of the pipe 21 is configured as a portion that does not allow water to permeate therethrough, and therefore resin or film is attached to the lower side of the pipe, or the lower pipe wall itself. Are formed as water impermeable parts.

Also in this method, the drain water taken out from the drain pipe 10 is stored in the drain pan 6 and sent to the sprinkler pipe 21 via the connection pipe 17 by the pump 15. The drain water accumulates in the pipe 21 up to the water level corresponding to the water impermeable portion, and beyond that, the drain water oozes out from the side surfaces on both sides of the pipe, oozes into the evaporation cloth 7, and is totally sprayed.

[0027]

As described above, according to the present invention, since the drain water is evenly and uniformly sprayed over the entire evaporation cloth, the entire surface of the evaporation cloth can be effectively utilized. Therefore, the evaporation efficiency is improved and the evaporation amount is significantly increased.
