However, in the above-described conventional configuration, since each of the evaporation plates is fitted and connected to the connection member only at the lower end, it is impossible to deteriorate over the years and when the entire weight of the evaporation plate is increased due to the water absorption of the drainage water. Maintain the standing position. When the upper end portion of the evaporation plate is placed in the posture of the adjacent evaporation plate, there is a problem that the ventilation between the evaporation plates is hindered and the evaporation processing efficiency is lowered.

Therefore, the applicant has first developed a configuration as shown in Fig. 25.

However, in the above configuration, the passage which is absorbed from the lower portion of the evaporation plate 100 and penetrates the both sides of the drainage in the evaporation plate 100 upward (indicated by a broken line arrow in Fig. 25) is cut by the upper portion. 102 cut off. At this time, since the drainage cannot pass through the both side edges of the evaporation plate (the inlet side of the slit 102), it is necessary to rise in the inner side of the evaporation plate 100 (inward of the deep portion of the slit 102), thereby making it difficult to drain. Penetration throughout the entire evaporation plate 100 causes a problem in which the evaporation processing capacity is limited.

The present invention has been made in view of solving the problems of the prior art, and provides an arrangement state in which a plurality of sheets of evaporation plates can be maintained and maintained, and also seeks to maintain the evaporation efficiency of the drainage by the penetration of the drainage.

That is, since the insertion hole of the connecting member is not a slit as in the prior art, even if an insertion hole is formed in the upper portion of the evaporation plate and is connected by the connecting member, it is absorbed from the lower portion of the evaporation plate and penetrates the evaporation plate upward. The drainage inside can also rise further after it reaches the insertion hole and returns to its surroundings.

Therefore, since the drainage is easily permeated throughout the entire evaporation plate (especially the upper portion) as compared with the conventional slit structure, the evaporation treatment efficiency of the drainage can be relieved by the addition of the connection portion due to the connection member, or It can be suppressed to a minimum.

Next, the drainage evaporating device 28 provided in the machine room 10 will be described in detail with reference to the enlarged views of the respective portions of FIGS. 7 and 8 in addition to the above-described respective drawings. In the present embodiment, the drain evaporation device 28 is provided with an auxiliary evaporation tray 29, an evaporation tray 30, and a drain tank 31.

The auxiliary evaporation tray 29 is disposed at the highest position within the evaporation tray, and temporarily accommodates the drainage flowing down from the cooler 44. The auxiliary evaporation tray 29 has a predetermined depth dimension, and an evaporation member 39, which will be described later, is provided in the auxiliary evaporation tray 29. An overflow pipe 40 that overflows the drain that has not been completely processed by the auxiliary evaporation tray 29 to the evaporation tray 30 is connected to the upper side surface of the auxiliary evaporation tray 29.

The evaporating tray 30 is disposed at a position lower than the auxiliary evaporating tray 29 and at a position higher than the drain tank 31, and constitutes a main evaporating tray in the evaporating tray. The evaporation tray 30 has a rectangular shape having a predetermined depth, and an electric heater 45 as a heating means for heating the drainage contained in the evaporation tray 30 is disposed on the bottom surface of the evaporation tray 30. The energization control of the electric heater 45 is performed by a control device C to be described later. Further, an evaporation member 41, which will be described later, is provided in the evaporation tray 30.

Further, on the bottom side surface of the evaporation tray 30, a drain plug 46 for discharging the drain water accommodated in the evaporation tray 30 to the drain tank 31 provided at a position lower than the evaporation tray 30 is provided. The drain port 46A of the drain plug 46 is opened on the drain groove 31, and in the present embodiment, the opening is formed above the opening 31A formed on the handle side of the drain groove 31. In the present embodiment, the drain plug 46 is capable of being opened and closed by hand.

Further, an overflow pipe 47 for draining the drain which is not completely processed by the evaporation tray 30 to the drain tank 31 is connected to the bottom surface of the evaporation tray 30. In the present embodiment, the upper end 47A of the overflow pipe 47 is open at a position higher than a predetermined high water level HWL, and the lower end 47B is opened on the drain groove 31. In the present embodiment, the opening is formed in the drain groove 31. Above the opening on the handle side, not shown.

Furthermore, in the evaporation tray 30, a low water level sensor (low water level detecting means) 48 and a high water level sensor 49 (high water level detecting means) are provided, the low water level sensor 48 is for detecting whether the drainage stored in the evaporation tray 30 is a predetermined lower water level LWL lower than the predetermined high water level HWL, and the high water level sensor 49 is used for detecting the evaporation in the evaporation.

The evaporating tray 31 is detachably inserted from the rail member 42. In the present embodiment, the evaporating tray 31A is pulled out by the handle 31B provided on the other surface side of the machine room 10, and the drain can be separately disposed outside. .

In the present embodiment, the drain groove 31 is formed in a groove shape in which the other surfaces are closed only by forming the aforementioned openings 31A on the side of the handle 31B. Therefore, even if the handle 31B is pulled out from the machine room 10 in a state where the drain is accommodated in the drain tank 31, the handle 31B is placed in a substantially vertical state on the upper side, and the stored drain can be transported to the place of disposal without leaking. .

Next, the above-described control device C will be described with reference to Fig. 9. The control device C is constituted by a general-purpose microcomputer, and at least the low water level sensor 48, the high water level sensor 49, and the control panel provided with various switches are connected to the input side of the control device C. (control panel) 51. A compressor 27, a condenser blower 26, a cooling air circulation blower (not shown), an electric heater 45, and a drain warning device (buzzer in the present embodiment) are connected to the output side of the control device C. Wait.

According to the above configuration, the high-temperature high-pressure gas refrigerant discharged from the compressor 27 when the compressor 27 is operated is condensed by the condenser 25, and is decompressed by a pressure reducing device (not shown), and then flows into the cooler 44. . Then, the refrigerant evaporates in the cooler 44, and at this time, the cooling action is exerted. Then, when the blower for cooling air circulation is operated, the air in the cold air duct 19 is sucked from the cold air suction ports 36, 37 on one side and the other side, and the cold air suction port 38 on one side, where heat is exchanged with the cooler 44. It is cooled. The cold air which rises in the cold air duct 19 in the duct member 11 reaches the ceiling 3, and the cold air discharge ports 32, 33 which are formed in the opening face 4 of the showcase, the opening 6 of the other side, and the upper edge of the side opening 7 from the respective openings, 34 is discharged toward each of the openings 4, 6, and 7. Then, after the air curtains are formed in the respective openings 4, 6, and 7, the cold air is repeatedly sucked into the cold air ducts 19 from the cold air suction ports 36 and 37 on the one surface and the other side, and the cold air suction ports 38 on the side surfaces. cycle.

Further, when the condenser blower 26 is operated in accordance with the cooling operation, the air outside the machine room 10 (outside air) is sucked into the machine room 10 via the intake port 20A formed in the one side panel 20 . The air taken in from the intake port 20A is cooled by the compressor 27 and the condenser 25, and after being disposed in the drain evaporation device 28 on the downstream side of the air, from the panel 21 provided on the other surface of the machine room 10 The exhaust port 21A is discharged to the outside.

By this cooling operation, frost is generated in the cooler 44, but the cooler 44 periodically defrosts. The defrosted water generated at the time of the defrosting or the drainage system dripped from the showroom 8 is dropped onto the bottom surface 2A of the heat insulating wall 2, and discharged to the inside of the machine room 10 via the drain port formed in the bottom surface 2A. Drain evaporation device 28.

Here, the drain discharged from the cooler 44 is first temporarily stored in the auxiliary evaporation tray 29 of the drain evaporation device 28 at the beginning. In the auxiliary evaporation tray 29, since the evaporation member 39 having the same configuration as that of the evaporation member 41, which will be described later, is provided, the effluent treatment of the drainage water contained in the auxiliary evaporation tray 29 can be promoted.

Further, the drain water that cannot be completely accommodated in the auxiliary evaporation tray 29 overflows to the evaporation tray 30 via the overflow pipe 40 formed on the upper side surface. Thereby, when the drain in the evaporation tray 30 is stored to the predetermined low water level LWL, the low water level sensor 48 disposed in the sensor box 50 detects the low water level of the drain, and the control device C makes the electric heat accordingly. The device 45 is energized and heated. Thereby, the evapotranation process of the drain contained in the evaporation tray 30 can be promoted. Further, since the evaporating member 41, which will be described later, is also provided in the evaporating tray 30, the evapotranspiration of the drain water contained in the evaporating tray 30 can be promoted.

By the heat treatment of the electric heater 45, the water level of the drain in the evaporation tray 30 rises more and is stored to the predetermined high water level HWL, and the high water level sensor 49 disposed in the sensor box 50 detects the drainage. The high water level, the control device C, accordingly operates the alarm operation by the alarm device 52. In this embodiment, the buzzer is used for reporting.

The user performs the drainage operation of the evaporation tray 30 based on the transmission of the buzzer. That is, the drain plug 46 provided in the evaporation tray 30 is opened to discharge the drain water in the evaporation tray 30 to the drain tank 31. Then, the drain groove 31 is pulled out from the machine room 10, and the drain water is drained to the outside. Thereby, it is possible to prevent the water immersion due to the leakage of the drainage in advance.

The buzzer's transmission can be stopped by a predetermined time of squeaking or a switch provided on the control panel 51. Therefore, when the draining operation cannot be performed immediately or when it is not noticed, it takes time until the drain plug 46 is opened. At this time, the drainage in the evaporation tray 30 becomes a water level higher than the predetermined high water level HWL, that is, the overflow pipe 47 which can be opened at the position from the upper end 47A overflows to the drain groove 31. Thereby, a fail safe mechanism is implemented.

Here, the drainage operation is performed by the alarm operation of the alarm device 52, but the drainage plug 46 may be arbitrarily opened before the busy time of the store or the like, and may be housed in the evaporation tray 30 so far. The drain is discharged to a drain tank 31 that is detachably inserted in the machine room 10, and is disposed of to the outside.

Since such a use pattern is possible, it is possible to drain most of the drainage in the evaporation tray 30 to the freely draining drain groove 31 without waiting until the evaporation tray 30 cannot completely accommodate the drainage. Externally disposed of. Therefore, regardless of the storage amount of the drainage of the evaporation tray 30, the disposal can be performed at an arbitrary timing, and the convenience can be improved.

In particular, the showcase 1 in which the three-side opening forms the showcase 8 has a large opening area, so that the amount of drainage is increased in the summer. Therefore, the management of the drainage is complicated, and the waste water is not limited to the disposal timing of the drainage in the evaporation tray 30. Therefore, the drainage treatment can be appropriately performed, and the water immersion of the installed floor due to the leakage of the drainage can be prevented in advance. . Further, in the present embodiment, since the auxiliary evaporation tray 29 is provided in the front stage of the evaporation tray 30, the effluent treatment capacity of the drainage of the entire drainage evaporation device 28 can be improved, and the number of times of disposal of the drainage can be reduced.

Further, in the embodiment, the drain plug 46 that drains the drain water in the evaporation tray 30 to the drain plug 46 of the drain tank 31 is not limited thereto, and may be controlled by the control device C. At this time, the drain plug 46 can be opened and closed by operating the drain plug opening and closing switch provided on the control panel 51. Thereby, it is possible to avoid the fact that the drain plug 46 is opened when the user does not notice, and the drain overflows from the inside of the drain groove 31 to the outside.

Next, the configuration of the evaporation member 41 will be described in detail with reference to Figs. 10 to 21 . Fig. 10 is a view as seen from the other surface side of the evaporation member 41, Fig. 11 is a view as seen from the side plate 9 side of the evaporation member 41, and Fig. 12 is a plan view showing the evaporation member 41. Further, since the evaporation member 41 provided on the evaporation tray 30 and the evaporation member 39 provided on the auxiliary evaporation tray 29 have substantially the same configuration, the evaporation member 41 provided in the evaporation tray 30 will be described here, but the configuration is omitted. The evaporation plate 53 which will be described later, which is provided in the evaporation member 39 of the auxiliary evaporation tray 29, is formed at a position corresponding to the drain pipe 55 which is guided from the cooler 44 to the drain pipe 55 of the auxiliary evaporation tray 29 as shown in Fig. 2, and is formed at a position other than the other. Different height dimensions. In Fig. 4, in order to avoid this situation in accordance with the shape of the drain pipe 55, three height dimensions are set so that the side opposite to the side plate 9 is the lowest and the side plate 9 side is the highest.

The evaporation member 41 placed in the evaporation tray 40 is composed of a plurality of sheets of the evaporation plate 53, a connecting member 60 for connecting the respective evaporation plates 53, and a pressing member for pressing the connecting member 60 to prevent it from coming off. 61 and so on.

The evaporation plate 53 is a member that expands the drainage area of the drainage water in the evaporation tray 40, and is easily permeated by the water supply and drainage, and is easily diffused from the surface of the evaporation plate 53. For example, the water absorbing fabric or the porous plastic material is excellent in water absorption. The material forms a rectangular plate.

In the two side portions of the lower portion of each of the evaporation plates 53 (the both side portions of the evaporation plate 53 are viewed from the front), as shown in FIG. 14, the lower insertion holes 54, 54 are provided, and the lower insertion holes 54 are provided. 54. The upper side portions of the upper portion of the evaporation plate 53 (the both side portions of the evaporation plate 53 are viewed from the front) are respectively provided with upper insertion holes 56, 56. The opening shapes of the insertion holes 54 and 56 are elongated and have the same shape, but each of the lower insertion holes 54 is formed to be long in the vertical direction (substantially perpendicular direction), and each of the upper insertion holes 56 is formed in the lateral direction (substantially The horizontal direction) is formed longer.

On the other hand, the connecting member 60 that connects the respective evaporation plates 53 is formed of a thin, wide, and elongated lightweight resin material having a small thickness and is elongated. The thickness of the connecting member 60 is substantially equal to or slightly smaller than the height (shorter one) of each of the insertion holes 54, 56, and the width dimension is set to be the same as that of each of the insertion holes 54, 56. The width (the size of the longer side) is approximately equal or slightly smaller. Further, the connecting member 60 is inserted into the lower insertion holes 54 and 54 formed at both side portions of the lower portion of each of the evaporation plates 53, and the upper insertion holes 56 and 56 formed at both side portions of the upper portion, respectively. And extending across the respective evaporation plates 53.

Therefore, the connecting member 60 inserted in the lower insertion hole 54 is easily deformed by a force in the lateral direction corresponding to the thickness direction, but has a certain degree of strength from a force corresponding to the upper and lower directions in the width direction, and is inserted in The connecting member 60 of the upper insertion hole 56 is easily deformed by a force from the upper and lower directions in the thickness direction, but has a certain strength to the force in the lateral direction corresponding to the width direction.

Further, the length dimension of the connecting member 60 is set to be slightly longer than the size between the outermost evaporation plates 53 and 53 in the juxtaposed state, whereby the length of the connecting member 60 is inserted in the state of being inserted into each of the evaporation plates 53. Both ends in the side direction protrude more outward than the outermost evaporation plates 53 and 53.

Further, a plurality of slits 57 are formed in the connecting member 60. Each of the slits 57 is formed at a predetermined interval across the longitudinal direction of the connecting member 60 as shown in Figs. 15 and 16 and is cut in a predetermined size from the longer edge portion toward the inside. The width of the slit 57 is set to be approximately equal to or slightly larger than the thickness of the evaporation plate 53 so that the evaporation plate 53 can enter and be engaged. Further, the interval of the slits 57 coincides with the interval between the respective evaporation plates 53 provided.

On the other hand, the pressing member 61 for pressing the respective connecting portion members 60 to prevent the falling from the insertion holes 54, 56 is also formed of a light-weight resin material having a thin thickness, a narrow width, and a long shape. shape. The thickness of the pressing member 61 is also set to be substantially equal to or slightly smaller than the height (shorter one) of each of the insertion holes 54, 56, and the width dimension is set to be smaller than the connecting member 60. Further, the pressing member 61 is inserted into the lower insertion holes 54 and 54 formed at both side portions of the lower portion of each of the evaporation plates 53 and the upper insertion holes 56 formed at both side portions of the upper portion, respectively, together with the connecting member 60. Within 56, and extending across the respective evaporation plates 53.

Therefore, in the embodiment, the pressing member 61 inserted into the lower insertion hole 54 is easily deformed by a force from the lateral direction corresponding to the thickness direction, but has a certain degree of force from the upper and lower directions corresponding to the width direction. The pressing member 61 that is inserted into the upper insertion hole 56 is also easily deformed by a force from the upper and lower sides in the thickness direction, but has a certain strength to the force in the lateral direction corresponding to the width direction.

Further, the length dimension of the pressing member 61 is also set to be slightly longer than the size between the outermost evaporation plates 53 and 53 in the juxtaposed state, whereby the length of the pressing member 61 is inserted in the state of being inserted into each of the evaporation plates 53. Both ends in the side direction protrude more outward than the outermost evaporation plates 53 and 53.

With the above configuration, the assembly procedure of the evaporation member 41 will be described next. First, as shown in Fig. 18 and Fig. 19, a predetermined number (multiple pieces) of the evaporation plates 53 are set at a predetermined interval in a jig (not shown). At this time, the lower insertion holes 54 and 54 and the upper insertion holes 56 and 56 of the respective evaporation plates 53 are arranged on the same line. Next, the connecting member 60 is inserted into the respective insertion holes 54, 56 from the outer side of the outermost evaporation plate 53 such as a black arrow.

At this time, the connecting member 60 inserted into the lower insertion hole 54 is in a state in which the cross section is in the vertical direction and the inlet of the slit 57 is in the lower direction. In other words, the entrance of the slit 57 is inserted in the direction of the edge side of the outer side of the lower insertion hole 54 as viewed from the center of the evaporation plate 53 (shown by a broken line in FIG. 19). In addition, the connecting member 60 that is inserted into the upper insertion hole 56 on the left side of the FIG. 14 is in a state in which the cross section is in the lateral direction, and the entrance of the slit 57 is in the direction of the left side. In addition, the connecting member 60 that is inserted into the upper insertion hole 56 on the right side of FIG. 14 has a horizontal cross-sectional direction and the inlet of the slit 57 faces the right side. In other words, the entrance of the slit 57 is inserted in the direction of the edge portion on the outer side of each of the upper insertion holes 56 as viewed from the center of the evaporation plate 53.

Further, the connecting members (four in total) are respectively inserted into the respective insertion holes 54, 56 of the evaporation plates 53. At this time, both end portions of the connecting member 60 protrude more outward than the outermost evaporation plates 53 and 53. Next, the connecting member 60 inserted through the lower insertion hole 54 is moved downward as indicated by the hollow arrow in FIG. 18, and the edge of the lower insertion hole 54 is viewed from the center of the evaporation plate 53 as the outer edge. The portion enters each of the slits 57 of the connecting member 60 to be engaged.

Further, the connecting member 60 that is inserted into the upper insertion hole 56 facing the left side of Fig. 14 is viewed from the center of the evaporation plate 53 as the outer side of the evaporation plate 53 as indicated by the hollow arrow in Fig. 19 (left in Fig. 14) The direction is moved, and the edge portion of the upper insertion hole 56 (the edge portion on the outer side viewed from the center of the evaporation plate 53) enters into each slit 57 of the connecting member 60 to be engaged. Further, the connecting member 60 that is inserted into the upper insertion hole 56 facing the right side of FIG. 14 is oriented outward from the center of the evaporation plate 53 as indicated by a hollow arrow in FIG. 19 (Fig. 14) In the right direction), the edge portion of the upper insertion hole 54 (the edge portion on the outer side viewed from the center of the evaporation plate 53) enters into each of the slits 57 of the connecting member 60 to be engaged.

In this state, the remaining space of the size of the slit 57 is formed between the insertion holes 54 and 56 in the respective insertion holes 60 and 56. The pressing member 61 is inserted into the remaining space. The pressing members 61 are respectively inserted into the remaining spaces in the respective insertion holes 54 and 56 of the evaporation plates 53 (four in total). At this time, both ends of the pressing member 61 protrude more outward than the outermost evaporation plates 53 and 53. Further, the cross-sectional shape (especially, the width dimension) of the pressing member 61 is set to be substantially equal to or slightly smaller than the remaining space (especially the longer one) of each of the insertion holes 54 and 56. The connecting member 60 inserted through the lower insertion hole 54 in this state is prevented from moving upward (the center direction of the evaporation plate 53), and the connecting member 60 inserted through the upper insertion hole 56 facing the left side of the Fig. 14 is also prevented from being blocked. The movement to the right (the center direction of the evaporation plate 53) also prevents the movement of the connecting member 60 inserted into the upper insertion hole 56 facing the right side of Fig. 14 to the left (the center direction of the evaporation plate 53). Thereby, the engagement of the slit 57 of the connecting member 60 and the edge of the insertion holes 54, 56 is formed.

Then, the connecting member 60 and the pressing member which are more protruded from the outermost evaporation plates 53 and 53 to the outer side are fixed to each other by a fastener (in the present embodiment, a stapler) 62 in a decomposable manner. The end of 61. Thereby, the connecting member 60 and the pressing member 61 are prevented from coming off from the insertion holes 54 and 56 of the respective evaporation plates 53, and the evaporation member 41 is completed.

According to the foregoing, the lower insertion holes 54 respectively formed at the lower portions of the both sides of the evaporation plate 53 and the upper insertion holes 56 formed at the upper portions of the evaporation plates 53 above the lower insertion holes 54 are provided, Further, since the lower insertion hole 54 is long in the vertical direction and the upper insertion hole 56 is long in the lateral direction, the connection member 60 that is inserted into the lower insertion hole 54 and the upper insertion can be inserted. The connecting member 60 of the hole 56 holds the respective evaporation plates 53 upright. Therefore, the interval between the evaporation plates 53 can be strongly maintained, and even if the drainage is absorbed, the upper end of the evaporation plate 53 can be made to abut against the adjacent evaporation plate 53, and the ventilation between the evaporation plates 53 is hindered, so that the evaporation processing efficiency is obtained. Reduced loss.

Further, the connecting member 60 that is inserted into the upper insertion hole 56 in a state in which the cross section is in the lateral direction is formed, and the connected evaporation plates 53 may be formed in a wave shape in the lateral direction, but in each of the evaporation plates 53. The lower insertion holes 54 on both sides of the lower portion are provided with the connecting members 60 that are inserted in the vertical direction of the cross section, so that the phase deformation can be performed in advance.

Further, the connecting member 60 has a plurality of slits 57 formed at predetermined intervals, and the insertion of the respective evaporation plates 53 is performed in a state where the connecting members 60 are inserted into the insertion holes 54, 56 of the respective evaporation plates 53. The edges of the through holes 54, 56 enter the respective slits 57 of the connecting member 60 and are engaged with each other, so that the slits 57 of the connecting member 60 are engaged with the edges of the insertion holes 54, 56 of the evaporation plate 53, that is, The interval between the respective evaporation plates 53 can be favorably maintained.

In particular, the edge portions of the outer insertion holes 54, 56 as viewed from the center of the evaporation plate 53 enter the slit 57 of the connecting member 60 and are engaged. When the edge portions of the insertion holes 54 and 56 in the center direction of the evaporation plate 53 are brought into the slits 57 of the connecting member 60, the operation of moving the connecting member 60 in the insertion holes 54 and 56 becomes the evaporation plate. The form in which the 53 is pressed in the center direction causes the evaporation plate 53 itself to wave inward. However, as shown in the embodiment, the edge portions of the insertion holes 54 and 56 on the outer side viewed from the center of the evaporation plate 53 are placed in the slits 57 of the connecting member 60, so that the occurrence of such a defect can be prevented.

Further, since the pressing member 61 that holds the edge of the insertion holes 54 and 56 of the evaporation plate 53 and the slit 57 of the connecting member 60 is provided, it is possible to prevent vibration or ventilation during transportation of the showcase 1 in advance. When the connecting member 60 moves, the edge portions of the insertion holes 54 and 56 are separated from the slit 57 to release the engagement, and the connecting member 60 is detached from the insertion holes 54 and 56, and the evaporation member 41 is decomposed or the like.

At this time, the pressing member 61 is elongated in a state of being inserted between the insertion holes 54 and 56 across the evaporation plates 53 , and the connecting member 60 is inserted into the insertion holes 54 and 56 of the respective evaporation plates 53 . Thereafter, the remaining space in the insertion holes 54 and 56 formed in the state in which the edge portions of the insertion holes 54 and 56 are respectively engaged with the slits 57 are inserted into the pressing member 61 to prevent the movement of the connecting member 60. The insertion of the pressing member 61 into the insertion holes 54 and 56 can suppress the disassembly of the evaporation member 41 by pressing the entire connecting member 60, and the assembly strength of the evaporation member 61 can be further advanced by the pressing member 61 itself. Promote the ground.

Further, since the connecting member 60 and the pressing member 61 are fixed to each other outside the outermost evaporation plate 53, it is possible to prevent the disconnection of the connecting member 60 and the pressing member 61 from the evaporation plate 53 due to vibration or ventilation. Further, since the connecting member 60 and the pressing member 61 are fixed to the outside of the evaporation plate 53, the fixing work can be easily performed.

The evaporating member 41 assembled as described above is placed in the evaporating tray 30 so as to pass through the wind from the condenser blower 26 in a direction substantially orthogonal to the direction in which the evaporating plates 53 are aligned, that is, from the side of the evaporating member 41. .

Since the evaporation member 41 is configured as described above, when the drain water is stored in the evaporation tray 30, the lower portion of the evaporation member 41 is immersed in the drain water stored in the evaporation tray 30, so that the drainage system is absorbed in each of the evaporation plates 53. The absorbed drainage system penetrates and rises by capillary action and moves to a portion exposed on the drainage. On the other hand, when the condenser is operated by the blower 26, each of the evaporation plates 53 exposed on the drain is ventilated, and the drain thus moved is evaded from the surface of the portion of the evaporation plate 53.

At this time, since the insertion holes 54 and 56 of the evaporation plate 53 passing through the connection member 60 are not as conventional slits, even if the upper insertion hole 56 is formed in the upper portion of the evaporation plate 53 and connected by the connection member 60, evaporation is performed. The lower portion of the plate 53 is absorbed by the drainage which penetrates upward into the evaporation plate 53 as indicated by the dotted arrow in Fig. 14, and can be further retracted after reaching the upper insertion hole 56 (in the upper portion of Fig. 14) The left and right sides of the through hole 56 are inserted and raised (Fig. 14).

Therefore, since the drainage is more likely to permeate throughout the entire evaporation plate 53 (especially the upper portion) than the conventional slit structure, it is possible to release the evaporation process efficiency due to the addition of the connection portion of the connection member 60, or Suppressed to a minimum.

Further, although the evaporation tray 30 is ventilated from the side of the evaporation member 41, the connection member 60 inserted into the upper insertion hole 56 of each of the evaporation plates 53 has a substantially transverse direction, so that evaporation from the evaporation is prevented. Ventilation of the side of the member 41. Therefore, ventilation between the respective evaporation plates 53 can be ensured, and evaporation processing efficiency can be ensured. Further, the connecting member 60 inserted through the lower insertion hole 54 has a substantially vertical cross section, but the connecting member 60 sinks on the drain stored in the evaporation tray 30, so that the ventilation is not affected.

Further, in the embodiment, according to the foregoing, the height dimension of the evaporation plate 53 of the evaporation member 39 corresponding to the position of the drain pipe 55 that guides the drainage from the cooler 44 to the auxiliary evaporation tray 29 is formed to be lower than that of the other evaporation plates 53. Further, the upper insertion hole 56 can be connected to each of the evaporation plates 53 at a position lower than the upper edge of the evaporation plate 53 having a lower height, that is, the evaporation pipe 55 can be avoided without any hindrance Plate 53. Therefore, even in the state in which the evaporation member 39 is mounted, the maintenance of the drain pipe 55 can be performed without hindrance.

In addition, Fig. 22 is a partially enlarged view showing another embodiment of the connecting member 60. At this time, the entrance of the slit 57 has a shape that gradually spreads toward the front end. According to this, if the entrance of the slit 57 of the connecting member 60 is expanded, the edge of the insertion holes 54, 56 of the evaporation plate 53 can be easily inserted into the slit 57, and the assembly work time of the evaporation member 41 can be remarkably shortened. .

Further, Fig. 23 shows the front side of other embodiments of the evaporation plate 53. At this time, the insertion hole 54 and the upper insertion hole 56 formed in the lower portion of the evaporation plate 53 are both in a cross shape, and the through hole 54 is inserted in the lower portion, except that the connection member 60 is inserted through the penetration portion 54A having a long vertical direction. A penetration portion 54B that is long in the lateral direction with a size substantially equal to or slightly larger than the width dimension of the pressing member 61 is formed. In addition, the upper insertion hole 56 is formed to have a size that is substantially equal to or slightly larger than the width dimension of the pressing member 61 in the vertical direction, except for the penetration portion 56A in which the connecting member 60 is inserted in the lateral direction. The through hole 56B is inserted.

Further, in the same manner as described above, the lower edge portion of the through portion 54A of the lower insertion hole 54 is engaged with the slit 57 of the connecting member 60. In this state, the upper edge of the connecting member 60 is formed flush with the lower edge of the penetration portion 54B. Then, the pressing member 61 is inserted into the penetration portion 54B. Further, the upper insertion hole 56 facing the left side of FIG. 23 is engaged with the slit 57 on the left side of the penetration portion 56A and the slit 57 of the connection member 60. In this state, the edge portion on the right side of the connecting member 60 is formed flush with the edge portion facing the left side of the penetrating portion 54B. Then, the pressing member 61 is inserted into the penetration portion 56B. Further, the upper insertion hole 56 facing the right side of FIG. 23 is engaged with the slit 57 on the right side of the penetration portion 56A and the slit 57 of the connection member 60. In this state, the edge portion on the left side of the connecting member 60 is formed flush with the edge portion facing the right side of the penetration portion 54B. Then, the pressing member 61 is inserted into the penetration portion 56B.

According to the configuration described above, the pressing member 61 is inserted into the insertion holes 54 and 56 of the respective evaporation plates 53 in the direction orthogonal to the connecting member 60, and the connecting member 60 is pressed. Therefore, the connecting member 60 can be pressed more reliably and effectively. The loss of the detachment from the insertion holes 54, 56 is prevented.

However, since the pressing member 61 inserted through the penetration portion 56B of the upper insertion hole 56 is in the vertical direction due to the longitudinal direction of the cross section, it is presumed that interference from the side of the evaporation member 41 is formed. In this case, as shown in Fig. 24, only the lower insertion hole 54 may have a cross shape similar to that of Fig. 23.

Further, when the insertion hole is formed in a cross shape, since it is difficult to fix the connecting member 60 and the pressing member 61 with the fastener 62 such as a staple, in this case, both are fixed to the evaporation plate 53 with an adhesive or the like. The outside can be.
