The present invention relates to an improvement in a device for spraying water to a provided evaporative cloth.

[0002]

2. Description of the Related Art Conventionally, as this type of drain water evaporator, there is one disclosed, for example, in Japanese Utility Model Laid-Open No. 2-24272.
As shown in FIG. 6, this is usually arranged in a machine room 2 provided below a case main body 1 for storing goods, in which a compressor 3, a condenser 4, a blower 5 and the like are arranged. Will be arranged.

As shown in FIG. 5, the drain water evaporating device stretches an evaporating cloth 7 in a meandering manner by a frame or a bridge 8 in a drain pan 6 for storing drain water, and sprays water over the evaporating cloth 7. A pipe 11 was provided, and a pump 12 for sending drain water in the drain pan 6 was provided in the same drain pan 6, and the end of the watering pipe 11 was connected to the pump 12.

[0004] A distal end of a drain pipe 10 communicating with a drain port of drain water opened at the bottom of the case body 1 is opened above the drain pan 6. A plurality of holes 11a are formed at appropriate intervals.

As a result, the drain water flowing from the case body 1 into the drain pipe 10 falls into the drain pan 6 and accumulates therein. The drain water in the drain pan 6 is sucked up by a pump 12 into a water sprinkling pipe 11, and a fine hole 11 for water sprinkling is formed.
Sprinkle water on the evaporating cloth 7 from a. Air that has passed through the compressor 3 and the condenser 4 by the blower 5 is applied to the evaporative cloth 7, and the moisture contained in the evaporative cloth 7 is evaporated by using the exhaust heat of the air.

[0006]

The sprinkling pipe 11 has an end connected to the pump 12 and the sprinkling pipe 1
The sprinkling pores 11a formed on the sprinkling pipe 11
Therefore, when a pump having a small power is used, the momentum of the drain water sucked from the drain pan 6 becomes small, so that the drain water does not reach the tip of the water sprinkling pipe 11 and is connected to the pump 12. Drain water is sprinkled only from the pores 11a located in the vicinity of the side where the drain water is sprayed, so that the drain water cannot be sprinkled over the entire evaporating cloth 7, and it is difficult to perform a good evaporating action. there were.

[0007] Further, since the fine pores 11a for watering are formed on the lower side, foreign substances mixed in the drain water sucked up may sink in the water and close the fine pores 11a. Also, the location of water spray on the evaporative cloth 7 is limited, and the drain water cannot be sprinkled on the entire evaporative cloth 7, so that it is difficult to perform the evaporative action well.

An object of the present invention is to eliminate the disadvantages of the prior art and to reduce the power of the pump even when foreign matter is mixed in the drain water, so that the drain water is evenly distributed over the entire evaporation cloth. It is an object of the present invention to provide a drain water evaporating device which is capable of spreading drain water efficiently.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention firstly provides a drain pan for storing drain water such as defrost water of a cooling unit in a freezing or refrigeration apparatus, and a method for evaporating the drain water. The drain water evaporating apparatus, comprising: an evaporating cloth provided in the drain pan, a sprinkling pipe disposed above the evaporating cloth, and a pump for sending drain water in the drain pan to the sprinkling pipe. The pipe was provided with a narrow water spout at the top at appropriate intervals.

[0010] Thereby, the drain water pumped to the sprinkler pipe reaches the tip of the sprinkler pipe and simultaneously from all the sprinkler ports simultaneously after the water level rises to the lower edge position of the sprinkler port in the sprinkler pipe. I drain. Therefore, the drain water can be spread all over the lower evaporative cloth, and the drain water can be efficiently evaporated.

Therefore, even if the power of the pump is reduced, the drain water can be spread to the tip of the watering pipe. Also, if foreign matter is mixed in the drain water, it will not block the water spout even if it sinks. In addition, it is possible to prevent watering from being hindered by foreign matter.

Secondly, the width of the sprinkling port is set to about 10 degrees from the top of the sprinkling pipe to the side, so that the opening of the sprinkling port is formed almost at the side of the sprinkling pipe. Since the drain water overflows from the sprinkling port, the direction of the flow is diffused while flowing along the outer side wall portion of the sprinkling pipe, so that water can be evenly sprayed to each part of the evaporating cloth.

From the same time.

Therefore, drain water can be spread over the entire evaporative cloth 7 below. Therefore, when the air that has passed through the compressor 3 and the condenser 4 is applied to the evaporative cloth 7 by the blower 5, the moisture contained in the evaporative cloth 7 is evaporated by using the exhaust heat.

Further, as described above, since a certain amount of the drain water is accumulated in the water pipe 11 and then sprayed simultaneously from all the water outlets 11b, the power of the pump is reduced and the drain water is reduced. Can be spread to the tip of the watering pipe, and the drain water can be evenly distributed to each part of the evaporating cloth 7.

Further, when foreign matter is mixed in the drain water, since the water spout 11b is formed at the upper part of the water sprinkling pipe 11, even if the foreign matter sinks, it does not block the water spout 11b. On the other hand, even if the foreign matter is floating, it is moved by the flow of the drain water, so that the water sprinkling port 11b will not be blocked, and it is possible to prevent the foreign matter from causing unevenness in the water spray location.

The width of the water spout 11b is set so that the angle from the top to the side of the water sprinkler pipe 11 is set to about 10 degrees. No opening is formed, and the drain water overflowing from the sprinkler port 11b is diffused in the direction of the flow while flowing along the outer side wall portion of the sprinkler pipe 11 so that water can be evenly sprayed to each part of the evaporating cloth 7. become.
