  As shown in FIGS. 5 and 6, the drain evaporator also has a slight gap by, for example, folding a long evaporating cloth into a drain pan (evaporating dish) 6 that is a tray for collecting drain water. A large number of pieces are arranged, and an evaporating cloth 7 in which a rectangular parallelepiped block body is formed as a set of multi-pieces and a watering pipe 11 positioned above the evaporating cloth 7 are disposed.

  A pump 12 for sending drain water in the drain pan 6 is disposed in the same drain pan 6, an end of the sprinkling pipe 11 is connected to the pump 12, and an upper portion of the sprinkling pipe 11 is narrowly spaced at an upper portion at an appropriate interval. A water inlet 11b was provided. Reference numeral 8 in the figure denotes a bridge rail for stretching the evaporating cloth 7 in a meandering manner.

  In addition, above the evaporating cloth 7, a tip of a drain pipe 10 communicating with a drain water drain opening opened at the bottom of the case body 1 is opened.

  As a result, the drain water flowing into the drain pipe 10 from the case body 1 falls into the drain pan 6 and accumulates here. The drain water in the drain pan 6 is sucked up by the water spray pipe 11 by the pump 12 and sprayed onto the evaporating cloth 7 from the water spray port 11b.

  Air that has passed through the compressor 3 and the condenser 4 by the blower 5 is applied to the evaporating cloth 7, and moisture contained in the evaporating cloth 7 evaporates using the exhaust heat.

  However, in such an evaporator, since it is not expected to spread even if it is dropped directly from the drain pipe 10 onto the upper surface of the evaporating cloth 7 that forms a rectangular parallelepiped block body, drain water is once supplied from the drain pipe 10 to the drain pan 6. If the water is stored and the drain water is absorbed upward by the capillary phenomenon of the evaporating cloth 7, it takes time to suck up, and it is rare that the water is sucked up uniformly to the upper part.

  In addition, even if the drain water stored in the drain pan 6 is sucked into the sprinkling pipe 11 by the pump 12 and sprinkled, the operation of the pump 12 is performed in anticipation that the drain water has accumulated in the drain pan 6 to some extent. It takes time to suck up.

  Further, the end of the sprinkling pipe 11 is connected to the pump 12, and the drain water is sprinkled only from the sprinkling spout 11 b formed in the sprinkling pipe 11. Drain water could not be sprinkled, and it was difficult to perform the evaporation effect well.

  Thus, the upper part of the evaporating cloth 7 is not used effectively and is wasted. Therefore, it is difficult to increase the evaporation amount in a state where there is a certain limit to increasing the height of the evaporation cloth due to the arrangement space and the like.

  In FIG. 4, as a proposal for improvement, a sheet-like evaporation cloth 21 is further laid in a canopy manner on the upper surface of the evaporation cloth 7 on which a rectangular parallelepiped block body is formed.

  In the figure, 22 is a hose connecting the pump 12 and the sprinkling pipe 11, 23a and 23b are support plates before and after the evaporating cloth 7, and 24 is a bridge rail made of evaporating cloth tape.

  The sheet-like evaporative cloth 21 first receives drain water from the sprinkling pipe 11 and connects it to the evaporating cloth 7. The sheet-like evaporative cloth 21 is sufficiently infiltrated with drain water, and from here the rectangular parallelepiped block It is quite difficult to spread the entire surface of the evaporating cloth 7 that forms the body.

  An object of the present invention is to eliminate the disadvantages of the conventional example, to effectively use the evaporating cloth, and to obtain a large amount of evaporation. In some cases, the evaporating cloth can be used without using the power of the pump. It is an object of the present invention to provide a drain evaporating apparatus for a showcase in which drain water is distributed evenly throughout the entire system so that the drain water can be efficiently evaporated.

  In order to achieve the above object, the present invention according to claim 1 is directed to a drain pan for storing drain water such as defrost water of a cooling unit in a refrigeration or refrigeration apparatus, and an evaporation provided in the drain pan for evaporating the drain water. A drain evaporating apparatus that forms a rectangular parallelepiped block body as a set of many pieces, and a sheet-like evaporation cloth is laid on the upper surface of the evaporating cloth of the rectangular parallelepiped block body. The cloth is formed by forming a downward side wall formed by bending the left and right sides, and inserting the downward side wall into the evaporating cloth piece to intersect.

  According to the first aspect of the present invention, the drain water flowing into the drain pipe from the case main body is received by the sheet-shaped evaporating cloth before going to the evaporating cloth of the rectangular parallelepiped block body.

  The sheet-shaped evaporation cloth forms a downward side wall formed by bending the left and right sides, and this downward side wall is inserted and intersected with the evaporation cloth piece, so that drain water penetrates into the side wall and many evaporation cloth pieces are spaced apart. It can be spread over the evaporating cloth of a rectangular parallelepiped block body.

  In this way, the side wall of the sheet-like evaporating cloth is also engaged with the evaporating cloth of the rectangular parallelepiped block body, and the drain water penetrating into the side wall can be directly transferred to the evaporating cloth of the rectangular parallelepiped block body. , Evaporating efficiency can be increased.

  The gist of the present invention described in claim 2 is that the drain pan is formed with a gap for inserting the evaporating cloth piece as a parallel slit at the bottom, and the lower end of the evaporating cloth piece is inserted therein.

  According to the second aspect of the present invention, the drain pan is formed with a gap for inserting the evaporating cloth piece as a parallel slit at the bottom, and the lower end of the evaporating cloth piece is inserted into the drain pan so that the evaporating cloth piece is firmly attached to the drain pan. In addition, the drain pan and the evaporating cloth piece are integrated, and the drain water from the drain pan to the evaporating cloth piece can be effectively sucked up.

  As described above, the drain evaporator of the showcase of the present invention is provided in the drain pan for storing drain water such as defrost water of the cooling unit in the refrigeration or refrigeration apparatus, and for evaporating the drain water. In a drain evaporation device that includes an evaporating cloth and forms a rectangular parallelepiped block body as a set of many pieces, the evaporating cloth can be used effectively and a large amount of evaporation can be obtained.

  In some cases, the drain water can be evenly distributed over the entire evaporation cloth without using the power of the pump, and the drain water can be efficiently evaporated. Therefore, it is necessary to provide a pump or a watering pipe on the drain pan. In addition, the cost can be reduced.

  Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 shows a first embodiment of a drain evaporator of a showcase of the present invention. A drain pan (evaporating dish) 6 for storing drain water such as defrost water of a cooling unit in a freezing or refrigeration apparatus, and the drain water are shown. In order to evaporate, an evaporating cloth 7 provided in the drain pan 6 is provided, and the evaporating cloth 7 forms a rectangular parallelepiped block body as a set of many pieces, which is the same as the conventional example.

  The evaporating cloth 7 that forms a rectangular parallelepiped block body by arranging a large number of evaporating cloth pieces 7a at intervals may be one in which the evaporating cloth pieces 7a are arranged with the short pieces independently arranged. The evaporating cloth 7 may be stretched in a meandering manner by, for example, nine folding.

  As shown in FIGS. 2 and 3, the drain pan 6 is formed with a gap 9 for inserting the evaporating cloth piece 7 a at the bottom as a parallel slit 9, and the lower end of the evaporating cloth piece 7 a is inserted therein.

  The slit 9 may be formed in the drain pan 6 by forming a step portion on the inner periphery of the bottom portion, and the bottom portion of the drain pan 6 may be formed in the thick bottom portion. You may do it.

  The evaporating cloth piece 7a is self-supporting by inserting its lower end into the slit 9, and is arranged in parallel at the interval of the slit 9 to form a rectangular parallelepiped block body. This eliminates the need for a bridge beam for tensioning the evaporating cloth piece 7a that has been conventionally required.

  The point that the sheet-like evaporation cloth 21 is laid on the upper surface of the evaporation cloth 7 is the same as that in FIG. 4, but in the present invention, the sheet-like evaporation cloth 21 is bent left and right to form the downward side wall 21a.

  A cut 13 is formed in the side wall 21a with a gap, and the upper end of the evaporating cloth piece 7a is inserted into the cut 13.

At this time, the incision 13 is formed in a triangular shape so that the incision width near the insertion port is slightly wider and the incision width on the back side is narrower, thereby facilitating the insertion operation.

  In this way, by inserting the sheet-like evaporating cloth 21 into the evaporating cloth pieces 7a of the evaporating cloth 7 and crossing them, the sheet-like evaporating cloth 21 also serves as a bridge.

  As another embodiment, the notch 13 may be provided on each evaporating cloth piece 7a side, and the downward side wall 21a of the sheet evaporating cloth 21 may be inserted therein.

  Before the drain water (see FIG. 7) flowing into the drain pipe 10 from the case body 1 goes to the evaporating cloth 7 of the rectangular parallelepiped block body, it is received by the sheet-like evaporating cloth 21 that is lowered as a side wall 21a. To.

  If it does in this way, drain water will be first stored in the sheet-like evaporation cloth 21, and will osmose | permeate into the side wall 21a of the sheet-like evaporation cloth 21, and will flow to the whole upper surface of the evaporation cloth 7 of a rectangular parallelepiped block body.

  Although the above embodiment showed the example which omitted the installation of the pump which sends drain water to the drain pan 6, and the sprinkling pipe which connects an edge part to this pump, these pumps and a sprinkling pipe are installed, and drain from a sprinkling pipe is shown. You may make it flow through the sheet-like evaporation cloth 21 made into the flat box body.
