(Knowledge and other information that forms the basis of this disclosure)
At the time when the inventors arrived at the idea of the present disclosure, there was a technique in which an evaporator was provided for a cooling/heating device to evaporate drain water.

In the conventional technology, a single evaporator is constructed by connecting a plurality of evaporator plates at a predetermined interval in the thickness direction by a connecting member. When using this evaporator, the evaporator plate is installed so as to stand on an evaporator tray in which drain water accumulates. However, when the evaporator plate absorbs drain water, it may become difficult for the evaporator plate to stand stably, and the evaporator plate may tilt and overlap in the arrangement direction. For this reason, in addition to the narrowing of the gap between each evaporator plate that serves as an air passage, when drain water accumulates in the evaporator tray, the area of the evaporator plate exposed above the drain water may decrease, and the evaporation promotion effect may decrease. In order to solve this problem, the inventors have come to constitute the subject of the present disclosure.
Therefore, the present disclosure provides an evaporation device that is easy to maintain the evaporation promotion effect.

Hereinafter, the embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanations than necessary may be omitted. For example, detailed explanations of already well-known matters or duplicate explanations of substantially the same configurations may be omitted.
It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

(Embodiment 1)
Hereinafter, the first embodiment will be described with reference to FIGS.

[1-1. Configuration]
[1-1-1. Overall configuration of cooling and heating equipment]
Fig. 1 is an external perspective view of a showcase 1 in accordance with embodiment 1. Fig. 2 is a side cross-sectional view of the showcase 1 in accordance with embodiment 1.
Below, a showcase 1 will be described as an example of a cooling/heating device. As shown in Figs. 1 and 2, the direction of arrow F will be the front of the showcase 1, and the direction of arrow R will be the rear of the showcase 1. When using left and right for the showcase 1, the left and right are used based on a worker looking at the showcase 1 from the front. When referring to the front side of the showcase 1, it may be called the front side. When referring to the rear side of the showcase 1, it may be called the rear side. Furthermore, the left and right direction of the showcase 1 may be called the width direction.

The showcase 1 has an insulated wall 2 with an enclosed cross section, such as a substantially C-shaped cross section or a substantially inverted C-shaped cross section. The showcase 1 has a main body 4 with an opening at the front, which is formed by attaching side panels to both sides in the width direction of the insulated wall 2. A duct plate 6 is attached to the inside of the enclosed shape of the insulated wall 2, spanning the bottom, back and top, with a gap between them, on the inner surface of the insulated wall 2. This forms a duct 7 between the duct plate 6 and the insulated wall 2, and forms a storage chamber 8 with an open front inside the enclosed shape of the duct plate 6. A machine room 21 is provided below the insulated wall 2 on the lower side of the storage chamber 8.

The upper end of the duct 7 communicates with a cold air outlet 14 located at the upper edge of the front opening of the storage chamber 8. The lower end of the duct 7 communicates with a cold air inlet 16 located at the lower edge of the front opening of the storage chamber 8. A cooler 18 that constitutes the refrigeration cycle of the cooling device is disposed at the lower center of the duct 7. A blower 17 for supplying cold air is disposed at the lower part of the duct 7.
The cold air intake port 16 is formed on the upper surface of a cold air intake member 116. A night cover for closing the opening of the storage room 8 when the store is closed may be stored in the cold air intake member 116 in a freely retractable manner.

Within the storage room 8, a first display shelf 31, a second display shelf 32, a third display shelf 33, and a fourth display shelf 34 are arranged in four stages and can be freely pulled out in the front-rear direction.
A steel back plate 27 is attached to the rear of the insulating wall 2 with a specified gap between it and the rear of the insulating wall 2. An exhaust duct 28 is formed between the back plate 27 and the insulating wall 2. The lower end of the exhaust duct 28 opens to the rear of the machine room 21 and communicates with the machine room 21. The upper end of the exhaust duct 28 opens above the showcase 1.
A panel 29 is disposed on the front side of the machine room 21 so as to be able to open and close the front side of the machine room 21 .

[1-1-2. Description of the machine room]
Fig. 3 is a plan view showing the inside of the machine room 21 of the showcase 1 in embodiment 1. Fig. 4 is a perspective view showing the inside of the machine room 21 of the showcase 1 in embodiment 1. Fig. 5 is a side cross-sectional view of the machine room 21 of the showcase 1 in embodiment 1.
A compressor 22, a condenser 23, and a condenser blower (blower) 24 which constitute the refrigeration cycle of the cooling device together with the cooler 18 are installed in the machine room 21. Also installed in the machine room 21 are an evaporator 50 according to the present embodiment, and an electrical box accommodating a power supply and a control board.

In the machine room 21, the condenser 23, the condenser blower 24, the evaporator 50, and the compressor 22 are arranged in this order from the front of the showcase 1 (arrow F direction). The condenser 23, the evaporator 50, and the compressor 22 extend in the left-right direction and are arranged approximately parallel. The condenser 23, the evaporator 50, and the compressor 22 are arranged so that they are horizontally long with respect to the air flow direction of the air sucked into the machine room 21 (arrow A direction in Figure 5).

In this embodiment, as shown in FIG. 3, the width W1 of the condenser 23 and the width W2 of the evaporation device 50 are configured to be approximately equal. Also, as shown in FIG. 5, the height H1 of the condenser 23 and the height H2 of the evaporation device 50 are configured to be approximately equal.

In this embodiment, three condenser blowers 24 are arranged at equal intervals in the width direction of the condenser 23. The condenser blowers 24 are axial fans. The air sent from the condenser blowers 24 forms a laminar flow.

[1-1-3. Description of the Evaporation Apparatus]
Fig. 6 is a front view of the evaporation device 50 in the embodiment 1. Fig. 7 is a perspective view of the evaporation device 50 in the embodiment 1.
The evaporator 50 comprises an upper evaporator tray (first evaporator tray) 51 which receives drain water such as dew water and defrost water discharged from the cooler 18 via a drain pipe 70, a lower evaporator tray (second evaporator tray) 52 which is located below the upper evaporator tray 51 and receives drain water that has overflowed from the upper evaporator tray 51, an evaporator pipe 53 which is provided within the upper evaporator tray 51 and exchanges heat with the drain water to supercool the refrigerant, a plurality of evaporators 100, 101, 102 which promote the evaporation of the drain water received in the evaporator trays 51, 52, and a drain water tank.

The upper evaporating dish 51 is made of a thermally conductive material. The upper evaporating dish 51 has a bottom surface portion 51d (see FIG. 6) that is substantially rectangular in plan view and extends in the left-right direction, and a surrounding wall portion 51e (see FIG. 7) provided around the bottom surface portion 51d. Two evaporating pipes 53 are provided inside the upper evaporating dish 51. The evaporating pipes 53 are provided substantially parallel to the upper evaporating dish 51 at a predetermined interval so as to follow the bottom surface portion 51d. The evaporating pipes 53 are part of the refrigerant piping that connects the compressor 22 and the condenser 23. The evaporating pipes 53 have a parallel portion 53a that is substantially parallel to the bottom surface portion 51d, and a rising portion 53b that rises substantially perpendicular to the parallel portion 53a. The evaporating pipes 53 extend from the upper evaporating dish 51 to the outside of the upper evaporating dish 51 via the rising portion 53b.

A number of evaporators 100, 101 are arranged above the parallel portion 53a of the evaporator pipe 53. In this embodiment, a tall evaporator 100 and an evaporator 101 that is shorter than the evaporator 100 are arranged. Note that no evaporator is arranged at the left end of the upper evaporator dish 51.

An upper evaporator tray drain outlet 59 is provided on the bottom surface 51d of the upper evaporator tray 51. The upper evaporator tray drain outlet 59 is provided slightly to the right of the left-right center portion 51b of the evaporator tray 51. The upper end 59a of the upper evaporator tray drain outlet 59 opens above the upper evaporator tray 51, and the lower end 59b opens directly above the lower evaporator tray 52. The upper evaporator tray drain outlet 59 discharges drain water that overflows above the upper part of the upper evaporator tray 51 into the lower evaporator tray 52 below.

The lower evaporating dish 52 has a bottom surface portion 52d (see FIG. 6) that is substantially rectangular in plan view and extends in the left-right direction, and a peripheral wall portion 52e (see FIG. 7) provided around the bottom surface portion 52d. The lower evaporating dish 52 is formed to be substantially the same size as the upper evaporating dish 51 in plan view.

An evaporation device 102 is provided inside the lower evaporation dish 52. The evaporation device 102 is provided across the entire lower evaporation dish 52 in the left-right direction.
A lower evaporating tray drain outlet 60 is provided on the bottom surface 52d of the lower evaporating tray 52. The lower evaporating tray drain outlet 60 is provided slightly to the left of the center of the lower evaporating tray 52. The upper end 60a of the lower evaporating tray drain outlet 60 opens above the lower evaporating tray 52, and the lower end 60b opens directly above the drain water tank. When drain water is not completely evaporated in the lower evaporating tray 52 and overflows beyond the upper part of the lower evaporating tray 52, the lower evaporating tray drain outlet 60 discharges the overflowed drain water into the drain water tank.

In this embodiment, the left-right width of the evaporator 102 provided in the lower evaporating dish 52 is approximately the same as the left-right width of the condenser 23. As a result, the high-temperature air that has passed through the condenser 23 is turned into a laminar flow by the condenser blower 24 and contacts the entire area of the evaporator 102, effectively promoting evaporation.
Therefore, even if a large amount of drain water is generated during a humid season, for example, most of the drain water evaporates, and the amount of drain water that has accumulated in the machine room 21 that needs to be disposed of can be reduced.

An evaporation pipe (part of the refrigerant piping) 53 is arranged in the upper evaporating dish 51, and in order to supercool the refrigerant by heat exchange with the drain water, a certain amount of drain water needs to be stored in the upper evaporating dish 51 at all times.
In this embodiment, the amount of drain water stored in the upper evaporator tray 51 can be adjusted by appropriately adjusting the size of the space S1 where the evaporator is not located and the space S2 above the evaporator 101.

[1-1-4. Overall configuration of the evaporation device]
FIG. 8 is a perspective view of the evaporation device 100 in the first embodiment.
The evaporation devices 100 to 102 can be configured in the same manner, except for differences in the number and size of the evaporation papers 110. The evaporation device 100 will be described below. Note that when the evaporation device 100 is placed in the showcase 1, it is placed upside down with respect to the state shown in Fig. 8. However, in the description of the evaporation device 100, for convenience of explanation, unless otherwise specified, the up and down are used based on the evaporation device 100 shown in Fig. 8.

The evaporation device 100 includes a plurality of evaporation papers 110. The plurality of evaporation papers 110 are arranged at a predetermined interval in the thickness direction. Therefore, the arrangement direction in which the plurality of evaporation papers 110 are arranged coincides with the thickness direction of the evaporation papers 110. The plurality of evaporation papers 110 are connected by connecting members 120, 121 that penetrate the evaporation paper 110 in the thickness direction. Alternatively, the plurality of evaporation papers 110 are connected by connecting members 120, 121 in their thickness direction. Both ends of the connecting members 120, 121 protrude outward in the arrangement direction from the evaporation papers 110 at both ends in the arrangement direction. Resin plates 130 harder than the evaporation papers 110 are fixed to both ends of the connecting members 120, 121. As a result, the plurality of evaporation papers 110 are sandwiched between the pair of resin plates 130 in the arrangement direction. The resin plates 130 are fixed to the connecting members 120, 121 by fixing bars 140, 141.

FIG. 9 is a perspective view of the evaporation paper 110 and a jig 150 used during assembly in the first embodiment.
The evaporation paper (evaporation plate) 110 is a plate-shaped member that absorbs drain water and evaporates it. One example of the material of the evaporation paper 110 is a nonwoven fabric such as polyester fiber as a base material, fine phenol particles are heat-cured on this base material to form a fixing agent, and the base material is further made hydrophilic, soaked in an alcohol-based solvent, and then dried. The evaporation device 100 is not limited to the evaporation paper 110, and may be composed of a polyester type, an acrylic type, a cellulose type, or the like.

The evaporation paper 110 is formed in a rectangular shape having a vertical width (vertical width) and a side width (horizontal width) perpendicular to the vertical width. The evaporation paper 110 in the embodiment for implementing the present disclosure is formed in a rectangular shape with a side width larger than the vertical width, but may be formed in a rectangular shape with a vertical width larger than the side width. More specifically, the evaporation paper 110 has an upper end (first outer peripheral end) 111, a lower end (second outer peripheral end) 112, a side end (third outer peripheral end) 113, and a side end (fourth outer peripheral end) 114 as outer peripheral ends. The upper end 111 is formed with a slit-shaped vertical insertion groove (first connection member insertion groove) 111a extending from the upper end 111 in the vertical direction (first direction) into the paper surface. A pair of vertical insertion grooves 111a are formed in the front and rear. In addition, at the side end 113, a slit-shaped lateral insertion groove (second connection member insertion groove) 113a is formed, which extends from the side end 113 in the front-rear direction (second direction) into the plane of the paper. Furthermore, at the side end 114, a slit-shaped lateral insertion groove (second connection member insertion groove) 114a is formed, which extends from the side end 114 in the front-rear direction (second direction) into the plane of the paper. The lateral insertion grooves 113a and 114a are formed at the same vertical position. The lateral insertion grooves 113a and 114a are formed below the vertical center. At the open end of each insertion groove 113a and 114a, a tapered guide portion 111b, 113b, 114b is formed, the groove width of which increases toward the outside of the plane of the paper.

When assembling the evaporation device 100, the evaporation paper 110 is set in the jig 150. The jig 150 is a block-shaped member extending along the arrangement direction of the evaporation paper 110. In this embodiment, the jig 150 has a cross-sectional shape that is approximately inverted T-shaped. In detail, the jig 150 has a thin plate-shaped base 153 that is long in the arrangement direction. The base 153 is fixed to a workbench, for example. A block-shaped lower support part 151 that extends along the arrangement direction of the evaporation paper 110 is provided on the upper surface of the base 153. The side width of the lower support part 151 is formed slightly smaller than the side width of the evaporation paper 110. An upper support part 152 that extends upward is formed in the center of the front and rear of the lower support part 151.

The lower support portion 151 and the upper support portion 152 are formed with slit-shaped insertion grooves 150a into which the evaporation paper 110 can be inserted. The insertion grooves 150a extend from the upper ends of the lower support portion 151 and the upper support portion 152 toward the base portion 153. Multiple insertion grooves 150a are formed at predetermined intervals according to the spacing between the evaporation papers 110.

Here, the height of the lower support portion 151 is formed so that it is lower than the horizontal insertion grooves 113a and 114a when the evaporation paper 110 is set in the jig 150. In addition, the side width of the upper support portion 152 is formed smaller than the front-to-back distance of the vertical insertion groove 111a of the evaporation paper 110.

The evaporation paper 110 is inserted into the insertion groove 150a. As a result, the evaporation paper 110 is held in an upright position, with the entire front-to-rear direction being held by the lower support part 151 and the central part in the front-to-rear direction being held by the upper support part 152. At this time, the evaporation paper 110 is easily aligned in the arrangement direction by being arranged so that the upper support part 152 is sandwiched between the vertical insertion groove 111a. When a predetermined number of evaporation papers 110 are set in the jig 150, the connection members 120, 121 are assembled to a set of the predetermined number of evaporation papers 110.

Fig. 10 is a perspective view of the case where the connecting members 120 and 121 are assembled in the embodiment 1. Fig. 11 is a view of Fig. 10 as seen from the arrangement direction of the evaporation paper 110.
In this embodiment, the connection members 120 and 121 include a first connection member 120 and a second connection member 121 .
The connecting members 120 and 121 are plate members having an elongated shape. The first connecting member 120 and the second connecting member 121 are formed to have the same length and cross-sectional shape. The connecting members 120 and 121 have a thickness smaller than the groove width of the insertion grooves 111a, 113a, and 114a of the evaporation paper 110.

The first connecting member 120 has a comb tooth portion 122 extending in the arrangement direction. The comb tooth portion 122 has a plurality of evaporator plate insertion grooves (comb tooth grooves in which a plurality of slits are arranged in a comb tooth shape) 122a formed in a cut shape. The evaporator plate insertion grooves 122a are formed at a predetermined interval in the longitudinal direction. The evaporator plate insertion grooves 122a are formed according to the arrangement interval of the evaporator paper 110 in the evaporation device 100. In other words, the comb tooth portion 122 has a plurality of spacer portions 122b (see FIG. 10) formed according to the arrangement interval of the evaporator paper 110. That is, the evaporator plate insertion groove 122a is formed by the space sandwiched between adjacent spacer portions 122b. By being inserted into the evaporator plate insertion groove 122a, the evaporator paper 110 is positioned with a predetermined interval.

Open end portions 123 are formed on both longitudinal sides of the comb-tooth portion 122. The open end portion 123 of the first connecting member 120 is formed with a rectangular opening hole 123a penetrating in the thickness direction.
The first connection member 120 is inserted into the vertical insertion groove 111a of the evaporation paper 110 set in the jig 150 (see FIG. 11 ). At this time, the upper end 111 side of the evaporation paper 110 is inserted into the evaporation plate insertion groove 122a of the comb-tooth portion 122 of the first connection member 120.

The second connecting member 121 differs from the first connecting member 120 in that it has an open end 124 instead of the open end 123 .
An opening groove 124a is formed in the opening end 124 of the second connecting member 121, the opening groove 124a being cut from the same side as the evaporation plate insertion groove 122a. In other words, the opening end 124 of the second connecting member 121 is formed in an L-shape.

The second connecting member 121 is inserted into the horizontal insertion grooves 113a and 114a of the evaporation paper 110 set in the jig 150 (see FIG. 11). In the horizontal insertion groove 113a, the side end 113 of the evaporation paper 110 is inserted into the evaporation plate insertion groove 122a of the second connecting member 121. In the horizontal insertion groove 114a, the side end 114 of the evaporation paper 110 is inserted into the evaporation plate insertion groove 122a of the second connecting member 121.

FIG. 12 is a perspective view showing a state in which the resin plate 130 according to the first embodiment is assembled.
In this embodiment, the first connecting member 120 is inserted into the vertical insertion groove 111a. The second connecting member 121 is inserted into the horizontal insertion grooves 113a, 114a. The evaporation paper 110 is inserted into each evaporation plate insertion groove 122a of the connecting members 120, 121. At this time, the guide portions 111b, 113b, 114b at the open ends of the insertion grooves 111a, 113a, 114a make it easier for the connecting members 120, 121 to be guided into the insertion grooves 111a, 113a, 114a, improving the ease of assembly to the evaporation paper 110.

It is preferable to insert the first connecting member 120 into the pair of front and rear vertical insertion grooves 111a, and then insert the second connecting member 121 into the horizontal insertion grooves 113a and 114a. In this case, when the first connecting member 120 is inserted vertically, the base 153 supports the evaporation paper 110, and when the second connecting member 121 is inserted horizontally, the upper support portion 152 of the jig 150 is sandwiched between the pair of front and rear first connecting members 120, making it difficult for the evaporation paper 110 to move horizontally.

The connecting members 120, 121 connect the evaporation paper 110 together while it is positioned at a predetermined interval in the thickness direction. At this time, the connecting members 120, 121 penetrate the evaporation paper 110, and the opening ends 123, 124 at both ends of the longitudinal direction of the connecting members 120, 121 protrude further outward in the arrangement direction than the evaporation paper 110 at both ends in the arrangement direction. In this embodiment, a resin plate 130 is fixed to the opening ends 123, 123 of the connecting members 120, 121.

The resin plate (support plate) 130 is configured to have a vertical width equal to or greater than that of the evaporation paper 110. In this embodiment, the resin plate 130 is a rectangular plate formed to the same size as the evaporation paper 110. The resin plate 130 is formed of resin, which is an example of a material harder than the evaporation paper 110. As the support plate, it is also possible to use a metal plate that is less susceptible to corrosion, such as a stainless steel plate, instead of the resin plate 130. The resin plate 130 is formed with slit-shaped through holes 130a and 130b according to the positions of the insertion grooves 111a, 113a, and 114a of the evaporation paper 110. In detail, the through holes 130a and 130b are formed according to the positions of the opening ends 123 and 124 of the connection members 120 and 121 inserted into the insertion grooves 111a, 113a, and 114a. In this embodiment, a pair of front and rear vertical through holes 130a are formed in the upper part of the resin plate 130. In addition, a pair of front and rear horizontal through holes 130b are formed in the lower part of the resin plate 130. As an example, the short side direction of the insertion grooves 111a, 113a, 114a provided in the evaporation paper 110 is approximately 0.5 mm to 1 mm larger than the width in the thickness direction of the connection members 120, 121 (in other words, the short side length of the cross section (see FIG. 11) of the connection members 120, 121). In addition, based on the connection members 120, 121, the short side direction of the slit-shaped through holes 130a, 130b provided in the resin plate 130 is approximately 2 mm larger than the width in the thickness direction of the connection members 120, 121, and the longitudinal direction is approximately 5 mm larger than the width in the short side direction of the connection members 120, 121 (in other words, the longitudinal length of the cross section (see FIG. 11) of the connection members 120, 121). As described above, by defining the relationship between the insertion grooves 111a, 113a, 114a provided in the evaporation paper 110 and the slit-shaped through holes 130a, 130b provided in the resin plate 130 and the connection members 120, 121, the connection members 120, 121 can be easily and reliably attached to the evaporation paper 110 and the resin plate 130, improving assembly.

As shown in FIG. 12, the resin plate 130 is attached from the outside in the arrangement direction of the evaporation paper 110, which is integrated by the connecting members 120 and 121, toward the evaporation paper 110. At this time, the opening end 123 of the first connecting member 120 is inserted into the vertical through hole 130a. Also, the opening end 124 of the second connecting member 121 is inserted into the horizontal through hole 130b. The opening ends 123 and 124 of the connecting members 120 and 121 protrude outward in the arrangement direction beyond the resin plate 130 while penetrating the resin plate 130. Fixing bars 140 and 141 are attached to the opening ends 123 and 124 of the connecting members 120 and 121.

FIG. 13 is a perspective view of the state in which fixing bars 140 and 141 are assembled in the first embodiment.
The fixed bars (fixed members) 140 and 141 are in the form of elongated flat plates and may be made of any material having spring properties, such as resin such as polypropylene, or a metal plate.
The first fixing bar 140 is formed corresponding to the first connecting member 120. In detail, the first fixing bar 140 has a length according to the arrangement width of the pair of front and rear first connecting members 120 in a state in which the evaporation paper 110 is connected. A protruding insertion portion 140a that protrudes outward in the longitudinal direction is formed on both longitudinal ends of the first fixing bar 140. The protruding insertion portion 140a is inserted into the opening hole 123a of the open end 123 of the first connecting member 120 and fits into the opening hole 123a.

The second fixing bar 141 is formed to correspond to the second connecting member 121. In detail, the second fixing bar 141 has a length according to the arrangement width of the pair of front and rear second connecting members 121 in a state where the evaporation paper 110 is connected. At both longitudinal ends of the second fixing bar 141, groove-shaped recessed insertion portions 141a are formed, which are cut inward in the longitudinal direction. The recessed insertion portions 141a are inserted into the opening grooves 124a of the second connecting member 121 and fit into the opening grooves 124a.

The insertion portions 140a, 141a of the fixing bars 140, 141 in one longitudinal direction are inserted into one of the connecting members 120, 121. Then, the fixing bars 140, 141 are bent, and the insertion portions 140a, 141a in the other longitudinal direction are inserted into the other connecting members 120, 121. At this time, for example, if an operator releases the fixing bars 140, 141, the fixing bars 140, 141 will return to a straight shape due to their rigidity, and connect the connecting members 120, 121 in a straight line. As a result, the resin plate 130 is fixed to the connecting members 120, 121 on both the top and bottom sides. In other words, the evaporation paper 110 is fixed to the resin plate 130 via the connecting members 120, 121. In this way, the evaporation device 100 shown in FIG. 8 is assembled.

As shown in Figures 1 to 5, the evaporation device 100 is placed in the upper evaporation dish 51 so that the upper end (one vertical end) 111 of the evaporation paper 110 is below the showcase 1, and the lower end (the other vertical end) 112 of the evaporation paper 110 is above the showcase 1. The arrangement direction of the evaporation paper 110 of the evaporation device 100 is the left-right direction of the showcase 1. As a result, the second connecting member 121 inserted into the horizontal insertion grooves 113a, 114a on the lower end 112 side is above the surrounding wall portion 51e (see Figure 6). The evaporation devices 101, 102 are also placed so that the connecting members of the horizontal insertion grooves are located above the surrounding walls 51e, 52e. As a result, the second connecting member 121 inserted into the horizontal insertion grooves 113a, 114a of the connecting members 120, 121 is arranged in the airflow path with its flat shape aligned with the air flow direction A (see FIG. 5) (i.e., the short side direction of the connecting members 120, 121 is the air flow direction A), making it difficult to obstruct the air flow between the evaporation papers 110 and making it easier for evaporation to be promoted by the evaporation devices 100-102. In particular, in this embodiment, the first connecting member 120 of the vertical insertion groove 111a, which is likely to have a large surface area intersecting with the air flow direction A, is arranged in the upper evaporation dish 51 outside the airflow path, making it easier to reduce obstruction of the air flow.

[1-2. Operation, etc.]
Next, the operation of the showcase 1 in the first embodiment will be described.
In this embodiment, the compressor 22 is driven to circulate the refrigerant in the refrigeration cycle, and the cooler 18 exchanges heat with the air inside the duct 7 to generate cold air. Then, the blower 17 for supplying cold air is operated to blow the air that has exchanged heat in the cooler 18 into the storage chamber 8, thereby cooling the storage chamber 8 to a predetermined temperature.

In the cooler 18, the air is cooled, so that moisture in the air condenses. The condensed moisture is guided to the evaporating dishes 51 and 52 of the evaporator 50 as drain water.
In the upper evaporating dish 51, the evaporating paper 110 of the evaporating device 100 absorbs and evaporates the drain water. At this time, in the evaporating device 100 of this embodiment, the resin plate 130 is fixed to both ends of the connecting members 120, 121 that connect the multiple evaporating papers 110 together, sandwiching the multiple evaporating papers 110 in the arrangement direction, and the resin plate 130 and the evaporating papers 110 are arranged in contact with the bottom surface portion 51d of the upper evaporating dish 51 (specifically, the parallel portion 53a of the evaporating pipe 53). That is, in this embodiment, the evaporating device 100 is supported by the resin plate 130, the connecting members 120, 121, and the fixing bars 140, 141, and the resin plate 130 makes it easy to maintain the multiple evaporating papers 110 in an upright state.

[1-3. Effects, etc.]
As described above, in this embodiment, the evaporation device 100 comprises a plurality of evaporator papers 110 arranged at a predetermined interval in the thickness direction, a pair of resin plates 130 which are harder than the evaporator papers 110 and arranged on both sides of the plurality of evaporator papers 110 in the arrangement direction of the evaporator papers 110, a plurality of connecting members 120, 121 which connect the plurality of evaporator papers 110 and the pair of resin plates 130 together while penetrating the plurality of evaporator papers 110 and the pair of resin plates 130 in the thickness direction, and fixing bars 140, 141 which fix the resin plate 130 to the opening ends 123, 124 of the connecting members 120, 121 in the arrangement direction.
According to this configuration, the plurality of evaporation papers 110 can be easily maintained in an upright state by the resin plate 130, the connecting members 120, 121, and the fixing bars 140, 141, thereby preventing the evaporation papers 110 from falling over and making it easy to maintain a predetermined distance between the evaporation papers 110. Therefore, even when drain water is accumulated in the evaporation trays 51, 52, the area of the evaporation papers 110 exposed from the drain water can be easily secured, making it easy to maintain the evaporation promotion effect.

As in this embodiment, the opening ends 123, 124 of the connecting members 120, 121 may be provided with an opening hole 123a or an opening groove 124a, and the fixing bars 140, 141 may be provided with a convex insertion portion 140a or a concave insertion portion 141a that is inserted into the opening hole 123a or the opening groove 124a.
According to this configuration, the fixing bars 140, 141 can be fixed to the connecting members 120, 121 by insertion, and the resin plate 130 can be easily fixed to the connecting members 120, 121.

Also, as in this embodiment, the connecting members 120, 121 are formed in the shape of plates having a longitudinal shape, and the connecting members 120, 121 are formed with a plurality of slit-shaped evaporation plate insertion grooves (comb-like grooves in which a plurality of slits are arranged in a comb-like shape) 122a into which any one of the upper end 111, side end 113 and side end 114 of the evaporation paper 110 is inserted, and the evaporation paper 110 is formed with a plurality of slit-shaped insertion grooves 111a, 113a, 114a extending from any one of the upper end 111, side end 113 and side end 114 toward the inside of the paper surface, and with the connecting members 120, 121 inserted into the insertion grooves 111a, 113a, 114a of the evaporation paper 110, the evaporation paper 110 may be inserted into the evaporation plate insertion grooves 122a of the connecting members 120, 121.
According to this configuration, it is possible to create a space on the inner side of the surface of the evaporation paper 110 where the insertion grooves 111a, 113a, and 114a are not formed. Therefore, the space can be utilized for assembly using the jig 150, so that the work time for assembling the evaporation device 100 can be shortened, and the number of steps can be easily reduced.

In other words, when the connection members 120 and 121 are inserted into slit-shaped holes that penetrate the inner side of the evaporation paper 110, rather than into the insertion grooves 111a, 113a, and 114a, the connection members 120 and 121 must be positioned on the inner side of the evaporation paper 110, and the connection members 120 and 121 must be slid along the inner side of the paper in order to insert the evaporation paper 110 into the evaporation plate insertion groove 122a. Therefore, it is difficult to provide space on the inner side of the evaporation paper 110, making it difficult to place a jig. In contrast, the above-mentioned configuration makes it easier to use the jig 150.

Furthermore, as in this embodiment, the multiple insertion grooves 111a, 113a, 114a may have a vertical insertion groove 111a extending in the up-down direction and horizontal insertion grooves 113a, 114a extending in the front-rear direction.
According to this configuration, the spacing of the evaporation paper 110 can be set at the portions of the connecting members 120, 121 inserted in different directions. Therefore, the evaporation paper 110 can be made less likely to fall over compared to when the spacing of the evaporation paper 110 is set at the portions of the connecting members 120, 121 inserted in the same direction. In other words, since the spacer portions 122b of the comb tooth portions 122 extend in intersecting directions, the evaporation paper 110 is less likely to rotate, and the evaporation paper 110 can be made less likely to fall over compared to when the spacer portions 122b extend in the same direction.

As described above, in this embodiment, the showcase 1 comprises a storage chamber 8, a cooler 18 for cooling the storage chamber 8, and a machine chamber 21. The machine chamber 21 comprises a condenser 23 and a compressor 22 connected to the cooler 18 by a refrigerant piping, and an evaporation device 50 for evaporating drain water generated in the cooler 18. In the showcase 1, the evaporation device 50 comprises evaporation trays 51, 52 for receiving the drain water, and an evaporation device 100 arranged in the evaporation trays 51, 52.
According to this configuration, it is possible to provide a showcase 1 in which the evaporation promotion effect can be easily maintained.

As in this embodiment, a condenser blower 24 is provided which draws in air from outside the machine room 21, and evaporator trays 51, 52 and evaporator 100 are arranged downwind of the condenser 23 when viewed from the air flow direction A inside the machine room 21, and evaporator 100 has plate-shaped connecting members 120, 121 having a longitudinal shape, and the connecting members 120, 121 may be arranged so that their short sides correspond to the air flow direction A.
According to this configuration, the air flow is less likely to be obstructed by the connecting members 120 and 121. Therefore, the warm air from the condenser 23 can easily flow between the evaporation papers 110, and the evaporation promotion effect of the evaporation device 100 can be easily improved.

(Embodiment 2)
Hereinafter, the second embodiment will be described with reference to FIG.

[2-1. Overall configuration of the evaporation device]
FIG. 14 is a perspective view showing a main part of an evaporation device 200 in the second embodiment.
The evaporation device 200 of embodiment 2 differs from the evaporation device 100 of embodiment 1 in that it has evaporation paper 210, a resin plate 230, and a fixed bar 240 instead of the evaporation paper 110, the resin plate 130, and the fixed bars 140, 141.

The evaporation paper 210 in the second embodiment differs from the evaporation paper 110 in that it has a lateral insertion groove 213a (the side end 114 side is in a position that cannot be seen in FIG. 14) that is deeper than the lateral insertion grooves 113a, 114a. Specifically, the lateral insertion groove 213a is formed to a depth that extends beyond the extension line of the vertical insertion groove 111a.

In the evaporation device 200 according to the second embodiment, a second connecting member 121 is inserted into the vertical insertion groove 111a instead of the first connecting member 120. Moreover, a first connecting member 120 is inserted into the horizontal insertion groove 213a instead of the second connecting member 121.
In the second embodiment, the first connecting member 120 and the second connecting member 121 are disposed on a straight line extending in the vertical direction.

The resin plate 230 in the second embodiment differs from the resin plate 130 in that a horizontal through hole 230b is formed at the position where the first connection member 120 penetrates when the evaporation paper 210 is connected.

The third fixed bar (fixed member) 240 in the second embodiment is a flat plate having a longitudinal shape. The third fixed bar 240 has a length according to the arrangement width of the upper second connecting member 121 and the lower first connecting member 120 when the evaporation paper 210 is connected. A concave insertion portion 141a is formed at one longitudinal end of the third fixed bar 240. A convex insertion portion 140a is formed at the other longitudinal end of the third fixed bar 240.

The third fixing bar 240 is fixed to the upper second connecting member 121 and the lower first connecting member 120, for example, by inserting the concave insertion portion 141a into the second connecting member 121, bending it in the vertical direction, and inserting the convex insertion portion 140a into the first connecting member 120. Thus, the resin plate 130 is fixed to the connecting members 120, 121 by the third fixing bar 240.

[2-2. Effects, etc.]
As described above, in this embodiment, the resin plates 230 are fixed to both sides in the arrangement direction of the plurality of evaporation papers 210. Therefore, in this embodiment as well, the plurality of evaporation papers 210 can be easily maintained in an upright state by the resin plates 230, the connection members 120, 121, and the fixing bar 240, so that the evaporation papers 210 are prevented from falling over, and the evaporation promotion effect of the evaporation device 200 can be easily maintained.

(Embodiment 3)
Hereinafter, the third embodiment will be described with reference to FIG.

[3-1. Overall configuration of the evaporation device]
FIG. 15 is a perspective view showing a main part of an evaporation device 300 according to the third embodiment.
The evaporation device 300 according to the third embodiment differs from the evaporation device 200 according to the second embodiment in that a resin plate 330 is provided instead of the resin plate 230 .

In the third embodiment, the resin plate 330 is configured to have a shorter side width than the evaporation paper 210. Two resin plates 330 are arranged on each side in the arrangement direction of the multiple evaporation papers 210. In other words, the resin plate 330 has a shape in which the front and rear central parts of the resin plate 230 in the second embodiment are omitted.

[3-2. Effects, etc.]
As described above, in this embodiment, the resin plates 330 are fixed to both sides of the arrangement direction of the plurality of evaporation papers 210. Therefore, in this embodiment, the plurality of evaporation papers 210 can be easily maintained in an upright state by the resin plates 330, the connecting members 120, 121, and the fixing bar 240, so that the evaporation papers 210 can be prevented from falling over, and the evaporation promotion effect of the evaporation device 300 can be easily maintained. In particular, in this embodiment, the resin plate 330 has a shape that does not have a central portion in the front and rear of the resin plate 230 and is divided with a gap in the front and rear. Therefore, the evaporation papers 210 adjacent to the resin plate 330 are easily exposed to the air flowing around them through the gaps in the resin plate 330, and the drain water evaporation effect is less likely to be hindered.

(Embodiment 4)
Hereinafter, the fourth embodiment will be described with reference to FIG.

[4-1. Overall configuration of the evaporation device]
FIG. 16 is a perspective view showing a main part of an evaporation device 400 according to the fourth embodiment.
The evaporation device 400 of embodiment 4 differs from the evaporation device 300 of embodiment 3 in that it has a first connecting member 120 and a cable tie 440 instead of the second connecting member 121 and the third fixing bar 240.

In the fourth embodiment, the first connecting member 120 is also inserted into the vertical insertion groove 111a.
Therefore, in the fourth embodiment, the opening end 123 in which the opening hole 123 a is formed protrudes from the resin plate 330 .

In the fourth embodiment, a cable tie (fourth fixing member) 440 is attached to the open end 123 of each of the first connection members 120, thereby fixing the resin plate 330 to the second connection member 121.

[4-2. Effects, etc.]
As described above, in this embodiment, the resin plates 330 are fixed to both sides in the arrangement direction of the plurality of evaporation papers 210. Therefore, in this embodiment as well, the plurality of evaporation papers 210 can be easily maintained in an upright state by the resin plates 330, the connection members 120, and the cable ties 440, so that the evaporation papers 210 are prevented from falling over, and the evaporation promotion effect of the evaporation device 400 can be easily maintained.

(Embodiment 5)
Hereinafter, the fifth embodiment will be described with reference to FIG.

[5-1. Overall configuration of the evaporation device]
FIG. 17 is a perspective view showing a main part of an evaporation device 500 according to the fifth embodiment.
The evaporation device 500 of embodiment 5 differs from the evaporation device 400 of embodiment 4 in that, instead of the first connecting member 120 and the cable tie 440, it has a second connecting member 121, a third connecting member 521, and a fourth fixing bar 541.

In the fifth embodiment, the third connecting member 521 is inserted into the vertical insertion groove 111a. The second connecting member 121 is inserted into the horizontal insertion groove 213a.

The third connecting member 521 differs from the second connecting member 121 in that the third connecting member 521 has an open end 524 instead of the open end 124 of the second connecting member 121 .
An opening groove 524a is formed in the opening end 524 of the third connection member 521, the opening groove 524a being cut from the opposite side to the evaporation plate insertion groove 122a of the comb tooth portion 122. The opening groove 524a has a groove width larger than the thickness of the resin plate 330. In other words, an L-shaped claw capable of engaging with the vertical slit hole 130a of the resin plate 330 is formed in the opening end 524 of the third connection member 521.

The fourth fixed bar (fixing member) 541 differs from the second fixed bar 141 in that it has a length corresponding to the arrangement width of the pair of second connection members 121 when the evaporation paper 210 is connected. Therefore, recessed insertion portions 141a that can be inserted into the open ends 124 of the second connection members 121 are formed at both longitudinal ends of the fourth fixed bar 541.

In the fifth embodiment, the resin plate 330 is attached at an angle to the third connection member 521 to which the evaporation paper 210 is connected, and the opening end 524 of the third connection member 521 is passed through the vertical through hole 130a. Then, the resin plate 330 is stood upright, and the opening end 124 of the second connection member 121 to which the evaporation paper 210 is connected is passed through the horizontal through hole 230b. Then, the fourth fixing bar 541 is fitted to the opening end 124 of the second connection member 121 protruding from the resin plate 330. As a result, the resin plate 330 is fixed to the second connection member 121 by the fourth fixing bar 541 at the lower part with the upper part hooked on the opening end 524 of the third connection member 521.

[5-2. Effects, etc.]
As described above, in this embodiment, the resin plates 330 are fixed to both sides in the arrangement direction of the multiple evaporation papers 210. Therefore, in this embodiment as well, the multiple evaporation papers 210 can be easily maintained in an upright state by the resin plates 330, the connection members 121, 521, and the fixing bar 541, so that the evaporation papers 210 are prevented from falling over, and the evaporation promotion effect of the evaporation device 500 can be easily maintained.

Other Embodiments
Note that, as examples of the technology disclosed in this application, the first to fifth embodiments have been described. However, the technology in this disclosure is not limited to these, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made.

In the first to fifth embodiments, the resin plates 130, 230, and 330 are exemplified as the support plates, and a resin structure is exemplified as an example of a material harder than the evaporation papers 110 and 210, but this is not limiting. For example, the support plates can also be manufactured from materials such as metals and ceramics that are resistant to corrosion.

In the first to fifth embodiments, the evaporation paper 110, 210 is illustrated as having a vertical insertion groove 111a and horizontal insertion grooves 113a, 114a, 213a extending in the up-down direction, but this is not limiting. The orientation, number, and position of the insertion grooves (connection member insertion grooves) 111a, 113a, 114a, 213a are arbitrary. Therefore, for example, the evaporation paper 110, 210 may have horizontal insertion grooves 113a, 114a, 213a instead of the vertical insertion groove 111a. In addition, it is desirable to provide the connection member insertion grooves in multiple directions so that the evaporation paper 110, 210 is less likely to tilt.

In the first to fifth embodiments, the evaporation paper 110, 210 is inserted into all of the evaporation plate insertion grooves 122a of the connecting members 120, 121, 521, respectively, but this is not limited thereto, and there may be evaporation plate insertion grooves 122a into which the evaporation paper 110, 210 is not inserted. This allows the number of sheets of evaporation paper 110, 210 connected to the connecting members 120, 121, 521 to be adjusted, making it easier to obtain an appropriate evaporation effect in the upper evaporation tray 51, for example.

(Additional Note)
The above description of the embodiments discloses the following techniques.

(Technology 1) An evaporation device comprising: a plurality of evaporator plates arranged at a predetermined interval in the thickness direction; a pair of support plates arranged on either side of the plurality of evaporator plates; a connecting member that connects the plurality of evaporator plates and the pair of support plates together while penetrating the plurality of evaporator plates and the pair of support plates in the thickness direction; and a fixing member that fixes an end of the connecting member to the support plates.
With this configuration, the multiple evaporation plates can be easily maintained in an upright position by the support plate, the connecting members, and the fixing members, preventing the evaporation plates from falling over and making it easier to maintain the spacing between the evaporation plates at a predetermined distance. Therefore, even when water is pooled in the evaporation tray, the area of the evaporation plates exposed from the water can be easily secured, making it easier to maintain the evaporation promotion effect.

(Technology 2) An evaporation device according to Technology 1, wherein an opening is provided at an end of the connection member, and an insertion portion is provided at the fixing member to be inserted into the opening.
With this configuration, the fixing member can be fixed to the connecting member by insertion, and the support plate can be easily fixed to the connecting member.

This configuration allows a space to be created inside the evaporation plate where no grooves for inserting the connecting members are formed, making it possible to use this space for assembly using a jig, thereby shortening the work time required to assemble the evaporation device and making it easier to reduce the number of steps.

(Technology 4) An evaporation device described in Technology 3, wherein the multiple connecting member insertion grooves have a first connecting member insertion groove extending in a first direction and a second connecting member insertion groove extending in a second direction different from the first direction.
With this configuration, the spacing between the evaporator plates can be set by the portions of the connecting members inserted in different directions, which makes it less likely for the evaporator plates to tip over compared to when the spacing between the evaporator plates is set by the portions of the connecting members inserted in the same direction.

(Technology 5) A refrigeration equipment comprising a storage chamber, a cooler for cooling the storage chamber, and a machine chamber, the machine chamber comprising a condenser and a compressor connected to the cooler by a refrigerant piping, and an evaporator for evaporating drain water generated in the cooler, the evaporator comprising an evaporator dish for receiving drain water, and an evaporator according to any one of Technologies 1 to 4 that is placed in the evaporator dish.
With this configuration, it is possible to provide a cooling/heating device that is able to easily maintain the evaporation promotion effect.

(Technology 6) A cooling/heating equipment as described in Technology 5, comprising a blower that draws in air from outside the machine room, the evaporator tray and the evaporator being arranged downwind of the condenser when viewed from the air flow direction inside the machine room, the evaporator having a plate-like connecting member with an elongated shape, and the connecting member being arranged so that its short side direction is the air flow direction.
With this configuration, the connection member is less likely to obstruct the flow of air, which makes it easier for air from the condenser to flow between the evaporation plates, and makes it easier to improve the evaporation promotion effect of the evaporation device.

As described above, the evaporator according to the present disclosure can be applied to devices that evaporate water such as drain water. In particular, the evaporator according to the present disclosure can be suitably applied to cold and heat appliances such as freezer-refrigerator showcases and refrigerators.
