Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a drain water evaporation device for evaporating drain water accumulated in a drain pan in a refrigeration or freezing device.

(Conventional technology) Conventionally, such a drain water evaporator is
For example, one disclosed in Japanese Utility Model Application Publication No. 58-135676 is known. 3 and 4 show a conventional device as seen in the above-mentioned publication. As shown in the figure, a compressor 3 and a condenser 4 constituting a refrigeration cycle are located in a machine room 2 under a case body 1. A drain water evaporation device including a blower 5 and a drain pan 6 is also provided. Drain water such as defrosting water from the cooler inside the main body is introduced into the drain pan 6 via the drain hose 7. Inside the drain pan 6, there is placed a frame 8 in which a plurality of iron wires are arranged in a staggered manner vertically, and an evaporation member 9 such as synthetic fiber cloth is stretched vertically in a meandering manner.
The water inside is sucked up by the evaporator and evaporates naturally.

(Problems to be solved by the invention) In the conventional device described above, drain water was introduced directly from the drain hose 7 into the drain pan 6, so the amount of evaporation was proportional to the height of the water sucked up by the evaporation member 9. As the amount of dust adhering to the surface of the evaporator increased, the height at which drain water was sucked up decreased, and as a result, the amount of evaporation also decreased as the usage time progressed.
Therefore, it is necessary to clean the evaporating member 9 at regular intervals, which is very complicated work. Also, if you neglect to clean the evaporation member, the amount of evaporation will decrease,
There was a problem with water overflowing from the drain pan. To improve this, for example, Utility Model Publication No. 56-144285 or Utility Model Publication No. 41-
Drain water evaporation devices as seen in Publication No. 12310 have been developed, but in both cases, a series of holes are provided in the tip of a drain pipe or an inclined conduit consisting of another pipe, and drain water is discharged from these holes. Therefore, since the drain water was discharged to a specific point on the evaporator, the amount of evaporation mainly depended on the suction height of the evaporator, and the same problems as those described above were involved.

The purpose of the present invention is to solve the above-mentioned problems, and therefore, to provide a drain water evaporator that maintains sufficient evaporation capacity even after long-term use and does not require cleaning.

(Means for Solving the Problems) The configuration that characterizes the present invention includes an evaporation member 9 such as a cloth or sheet (paper) placed in a drain pan that stores drain water and stretched vertically in a meandering manner; A shallow container-shaped drain receiver 10 is provided on the evaporator member to temporarily receive and drip drain water, and has a pore formed in the bottom surface, and the pore allows the drain water to flow over the entire surface of the evaporator member. It is formed to be pulled down.

(Operation of means for solving the problem) Drain water flowing out from the drain hose enters the drain receiver 10, drops from there over the entire surface of the evaporation member 9, and is absorbed. Drain water not absorbed by the evaporation member is received by the drain pan 6. Therefore, even if dirt adheres to the evaporator, the drain water is absorbed by the evaporator and evaporated there.

(Example) Next, an example of the present invention will be described with reference to the drawings. The drain water evaporation device according to the present invention is also the first.
As shown in the drawings and FIG. 2, it includes a drain pan 6 and an evaporation member, for example, an evaporation cloth 9, which is placed in the drain pan 6 and stretched vertically in a meandering manner. The drain pan 6 is a refrigerating device, that is, a refrigerating or freezing case.
It is installed in various storage cases equipped with coolers, such as refrigerators and freezers, and receives drain water such as defrost water generated therein. The evaporation cloth 9 is made of water-absorbent cloth and is stretched vertically in a meandering manner. Therefore, in many cases, a frame 8 is used in which a plurality of wires are arranged vertically in a staggered manner.

Furthermore, in this drain water evaporator, as shown in FIG. 1, a drain receiver 10 is placed above the evaporating cloth 9 and below the drain hose 7, that is, between them, in order to temporarily receive the drain water from the drain hose 7. provided. As shown in FIG. 2, the drain receiver 10 is composed of a shallow container, and a plurality or a large number of pores 11 are formed in the bottom surface of the container.
Through the evaporator cloth 9, drain water is dripped over the entire surface of the evaporator cloth 9. Therefore, the size of each pore 11 is suitable for dripping water. In addition, the pores 11 are connected to the drain receiver 1 as shown in FIG.
Preferably, they are uniformly distributed over the entire bottom surface of 0.

Drain water flowing out from the drain hose 7 first enters the drain receiver 10 , and when it accumulates in the drain receiver 10 to a certain extent, it overcomes the surface tension in each pore 11 and drips from the pores 11 , covering the entire surface of the evaporator cloth 9 . and evaporated on contact with air. In order to promote evaporation, it is preferable to apply air to the evaporation cloth 9 using the blower 5. Drain water that drips from the drain receiver 10 and is not absorbed by the evaporation cloth 9 is received in the drain pan 6. In addition to the evaporation cloth, the evaporation member 9 may be a thin, flexible, and water-absorbing sheet such as paper.

(Effects of the invention) As described above, according to the invention, the drain water flowing out from the drain hose is dripped over the entire surface of the evaporation member in the drain pan, so even if dirt adheres to the evaporation member, Drain water can be absorbed over the entire surface of the evaporation member and can be evaporated suitably. Therefore, even if the evaporation member becomes dirty due to the passage of time of use, the evaporation capacity does not decrease, and therefore, there is a remarkable effect that cleaning of the evaporation member is not necessary.
