[0061] (Insights, etc. that form the basis of this disclosure)

[0062] When the inventors conceived of the present disclosure, there was a technology in which, in a showcase including a condenser as a heat exchanger, a blower for blowing air toward the condenser, and an evaporation device for storing condensed water and evaporating it, the blower blows the air that has exchanged heat with the condenser toward the evaporation device.

[0063] In addition, in a display case equipped with an evaporation device, the evaporation device is sometimes not arranged on the downstream side of the blower that sends air to the condenser. In such a display case, another blower different from the blower that sends air to the condenser is provided, and air is sent to the evaporation device by the other blower to promote evaporation of condensed water stored in the evaporation device.

[0064] However, in a showcase in which the evaporator is not disposed downstream of the blower that sends air to the condenser, the inventors have discovered that the air that has exchanged heat with the heat exchanger cannot be utilized, and have developed the subject matter of the present disclosure to solve this problem.

[0065] Therefore, the present disclosure provides a refrigeration unit and a display cabinet capable of efficiently evaporating condensed water.

[0066] Hereinafter, the embodiments are described in detail with reference to the accompanying drawings. However, sometimes, a detailed description beyond what is necessary is omitted. For example, sometimes, a detailed description of a known matter or a repeated description of a substantially identical structure is omitted. This is to avoid the following description being too lengthy and to make it easy for those skilled in the art to understand.

[0067] In addition, the drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0068] (Implementation Method 1)

[0069] Below, use Figure 1 to Figure 4 Embodiment 1 is described. Symbol FR shown in each figure indicates the front of the showcase which is set on the installation surface and is in a state of normal use, symbol UP indicates the top of the showcase, and symbol LH indicates the left of the showcase. In the following description, each direction is a direction along these directions of the showcase.

[0070] [1-1. Structure]

[0071] [1-1-1.Structure of display cabinet]

[0072] Figure 1 It is a perspective view of the showcase 1 according to the embodiment of the present disclosure.

[0073] like Figure 1 As shown, the showcase 1 is a device that is placed on the floor of a supermarket, convenience store, or the like, and displays beverages, foods, or other products in a refrigerated or cooled state. The showcase 1 of this embodiment is a so-called open showcase.

[0074] Figure 2 is Figure 1 The cross-sectional view of the showcase 1 is cut at the plane II. The plane II is an imaginary plane passing through the condenser 32 and the electrical installation box 38 in the left-right direction of the showcase 1.

[0075] The showcase 1 includes a housing body 10. The housing body 10 includes a frame structure with an open front surface.

[0076] like Figure 2 As shown, the housing body 10 includes a heat insulating wall 14. The heat insulating wall 14 is formed of various heat insulating materials such as polyurethane foam or polystyrene foam. The heat insulating wall 14 forms the top surface, back surface and bottom surface of the housing body 10. The housing body 10 includes side plates 16 forming left and right side surfaces.

[0077] The housing body 10 is provided with a partition wall 18. The partition wall 18 is a plate-like member disposed facing each of the heat insulating walls 14 forming the top and back surfaces at a predetermined interval inside the housing body 10. The partition walls 18 are connected to each other.

[0078] A plurality of display racks 12 capable of placing commodities are provided on the partition wall 18 extending in the vertical direction of the housing body 10. The display racks 12 are arranged at predetermined intervals from each other in the vertical direction. In the present embodiment, the display racks 12 located at the bottom layer are arranged at predetermined intervals from the heat insulating wall 14 forming the bottom surface of the housing body 10. Therefore, inside the housing body 10, the space surrounded by the side panels 16, the partition wall 18 and the display racks 12 at the bottom layer functions as a display room 11 for arranging exhibits such as commodities.

[0079] The housing body 10 is provided with a duct space 13. The duct space 13 is a space surrounded by the heat insulating wall 14, the side plates 16, the partition wall 18, and the display shelf 12 at the bottom.

[0080] The housing body 10 is provided with a blowout port 15. The blowout port 15 is provided at a front end portion of a partition wall 18 facing the top surface of the housing body 10. The blowout port 15 is an opening portion that allows the duct space 13 and the display shelf 12 to communicate with each other.

[0081] The casing body 10 is provided with a suction port 17. The suction port 17 is formed in a suction member 19 provided at the front end of the display shelf 12 at the lowest stage. The suction port 17 is an opening that allows the duct space 13 and the display shelf 12 to communicate with each other.

[0082] An evaporator 34 as a heat exchanger and a blower 40 for blowing air to the evaporator 34 are housed in the duct space 13. The evaporator 34 is a so-called fin-tube type heat exchanger. The blower 40 is a so-called axial flow fan.

[0083] Furthermore, a refrigerant pipe 31 connected to the evaporator 34 and a pressure regulating mechanism such as an expansion valve connected to the evaporator 34 via the refrigerant pipe 31 may be provided in the pipe space 13 .

[0084] The showcase 1 includes a back plate 2. The back plate 2 is a plate-shaped member forming the back of the showcase 1. The back plate 2 is arranged on the opposite side of a partition wall 18 extending in the vertical direction of the housing body 10 across a heat insulating wall 14 forming the back of the housing body 10.

[0085] An exhaust space 5 is provided in the showcase 1. The exhaust space 5 is a space surrounded by the heat insulating wall 14, the side panels 16, and the back panel 2. The heat insulating wall 14, the side panels 16, and the back panel 2 form a duct-like structure by providing the exhaust space 5. The exhaust space 5 is connected to the outside of the showcase 1 through an opening provided at the top of the showcase 1.

[0086] [1-1-2. Structure of the machine room unit]

[0087] The showcase 1 includes a machine room unit 20 . The machine room unit 20 is a unit including various devices and components related to cooling of the showcase 1 .

[0088] The machine room unit 20 includes a unit body 22, which is a frame body on which the casing body 10 is placed. A machine room 21 is provided inside the unit body 22, and is a space for storing various devices and components related to cooling of the display room 11. The machine room 21 communicates with the exhaust space 5 via an opening provided at the top of the unit body 22.

[0089] The unit body 22 includes a bottom plate 24 that forms the bottom surface of the unit body 22 and the showcase 1 .

[0090] The unit body 22 includes a plate-shaped skirting board 26 forming the front surface of the unit body 22. The skirting board 26 is provided with an air inlet 23 which is a through hole penetrating in the front-rear direction. In the present embodiment, the skirting board 26 is formed to be detachable from the unit body 22.

[0091] In the present embodiment, the rear surface of the unit main body 22 is formed by the lower end portion of the back plate 2 .

[0092] The machine room unit 20 corresponds to the “refrigeration unit” of the present disclosure.

[0093] The unit body 22 corresponds to the “frame” in the present disclosure.

[0094] Figure 3 21 is a top view of the machine room 21. Figure 3 In the figure, for the convenience of explanation, the electrical installation box 38 is indicated by a double-dashed line. Figure 3 In FIG. 1 , for convenience of explanation, the air blowing direction A of the air blower 42 is indicated by a single-dot chain line.

[0095] like Figure 3 As shown, a compressor 30 and a condenser 32 as a heat exchanger are arranged in the machine room 21. The compressor 30, the condenser 32, and the evaporator 34 are connected to each other via a refrigerant pipe 31, and a refrigeration circuit for cooling the display room 11 is formed.

[0096] The refrigerant sent by the compressor 30 flows in the refrigeration circuit. In this embodiment, HFC (hydrofluorocarbon), propane, etc. are used as the refrigerant of the showcase 1. In the showcase 1, by using HFC and propane, the amount of refrigerant filled in the refrigeration circuit can be reduced.

[0097] In addition, the showcase 1 is not limited to this, and other refrigerants such as carbon dioxide refrigerant may be used.

[0098] The compressor 30 is disposed substantially in the center in the left-right direction of the machine room 21. The compressor 30 is disposed at a position closer to the rear surface side than the front surface of the unit main body 22.

[0099] In the present embodiment, the condenser 32 is a so-called fin-tube type heat exchanger. The condenser 32 is formed in a substantially rectangular parallelepiped shape. In the machine room unit 20, the condenser 32 is arranged along the skirting board 26. The condenser 32 is provided at a position overlapping with the air inlet 23 and the compressor 30 when viewed from the front of the machine room unit 20.

[0100] A plurality of air blowers 42 for blowing air toward the condenser 32 are provided in the machine room 21. A plurality of air blowers 42 are attached to a surface of the condenser 32 that faces the rear surface of the unit main body 22.

[0101] The blower 42 of this embodiment is an axial flow fan similarly to the blower 40. The blower 42 is a so-called suction type blower.

[0102] When the blower 42 is driven, air outside the machine room unit 20 is taken into the machine room 21 through the air intake port 23. The air taken into the machine room 21 passes between the fins of the condenser 32, thereby exchanging heat with the refrigerant flowing in the condenser 32. The blower 42 sends the air that has passed through the condenser 32 toward the rear of the unit body 22. In the following description, the direction in which the blower 42 sends out the air in this way is referred to as the air supply direction A. The air supply direction A is a direction along the front-rear direction.

[0103] The air passing through the condenser 32 is sent to the rear of the machine room 21 by the blower 42, and at least a part of it is blown to the compressor 30. Thus, the compressor 30 is cooled. That is, at least a part of the air sent by the blower 42 becomes cooling air for the compressor 30.

[0104] The air sent by the blower 42 to the rear of the machine room 21 is exhausted to the outside of the showcase 1 through the exhaust space 5 .

[0105] Figure 4 21 is a front view of the machine room 21. Figure 4In the figure, for the convenience of explanation, the skirting board 26, the condenser 32 and the electrical installation box 38 are omitted. Figure 4 In FIG. 1 , for convenience of explanation, the condenser 32 is indicated by a double-dashed line.

[0106] like Figure 4 As shown, the air blowers 42 are dispersedly arranged at predetermined intervals on the back side of the condenser 32. The air blowers 42 are arranged in the left-right direction on the surface of the condenser 32 that is opposite to the back side of the unit body 22, and are arranged in multiple rows in the up-down direction. In the present embodiment, the air blowers 42 are arranged in two rows, one above the other. In the lower row, the air blowers 42 are arranged at positions where the lower ends of the air blowers 42 are close to the lower ends of the condensers 32. In the upper row, the air blowers 42 are arranged at positions where the upper ends of the air blowers 42 are close to the upper ends of the condensers 32.

[0107] Thus, when viewed from the front, the air passes through the entire condenser 32 and exchanges heat with the refrigerant.

[0108] like Figure 3 As shown, the machine room 21 is provided with an accumulator 36 . The accumulator 36 forms a refrigeration circuit together with the compressor 30 and the like. The accumulator 36 is connected to the suction side of the compressor 30 via the refrigerant pipe 31 .

[0109] An electrical installation box 38 is disposed in the machine room 21. In the present embodiment, the electrical installation box 38 is a box body disposed at a position close to the right side surface of the unit body 22. The electrical installation box 38 is disposed to the right of the compressor 30 and the condenser 32 in the machine room 21. The electrical installation box 38 contains a control substrate for controlling each part of the showcase 1, a power supply device for supplying power to each part of the showcase 1, and the like. The electrical installation box 38 is connected to each part of the showcase 1 via various wirings such as signal lines and power supply lines.

[0110] In the machine room 21, the plurality of blowers 42 are centrally arranged on the surface of the condenser 32 that is opposite to the back surface of the unit body 22. Thus, in the machine room 21, the wiring connecting the plurality of blowers 42 and the electrical installation box 38 can be centrally arranged, and the length of the wiring can be shortened and the routing of the wiring can be simplified.

[0111] [1-1-3. Structure of evaporating dish]

[0112] Figure 5 21 is a perspective view of the machine room 21. Figure 5 In the figure, for the convenience of explanation, the condenser 32 and the blower 42 are omitted.

[0113] like Figure 5As shown, a drain pipe 48 is provided at the upper part of the machine room unit 20. The drain pipe 48 is a tubular member that connects the duct space 13 with the machine room 21. One end of the drain pipe 48 is connected to the lower end of the housing body 10 and opens in the duct space 13. The other end of the drain pipe 48 opens downward at the machine room 21.

[0114] The machine room 21 is provided with a plurality of legs 52. The legs 52 are columnar members that are provided to stand upward from the bottom plate 24 at a predetermined height. In the present embodiment, four legs 52 are arranged between the plurality of blowers 42 and the compressor 30.

[0115] The plurality of legs 52 support the first evaporation dish 50. The first evaporation dish 50 is an evaporation device for storing condensed water and evaporating it. Figure 3 As shown in FIG. 1 , the first evaporating dish 50 is formed into a long box shape when viewed from above. Figure 3 , Figure 5 As shown, the first evaporating dish 50 has a predetermined depth dimension and has an opening 51 with an open top surface.

[0116] The first evaporating dish 50 includes a lower bottom 54 and an upper bottom 56 .

[0117] like Figure 4 , Figure 5 As shown, the lower bottom portion 54 forms the bottom surface of the first evaporating dish 50 from one end portion to a position close to the other end portion in the length direction of the first evaporating dish 50 .

[0118] The upper bottom portion 56 is disposed at the other end portion in the length direction of the first evaporating dish 50. Figure 4 As shown, the upper bottom portion 56 forms the bottom surface of the first evaporating dish 50 at the other end portion in the longitudinal direction of the first evaporating dish 50. The upper bottom portion 56 is located above the lower bottom portion 54. Therefore, the portion of the first evaporating dish 50 located at the other end portion in the longitudinal direction is formed shallower than other portions.

[0119] like Figure 3 As shown, the upper bottom 56 is formed shorter than the lower bottom 54 in the longitudinal direction of the first evaporating dish 50. The lower bottom 54 and the upper bottom 56 are both arranged at positions overlapping the opening 51 in a plan view.

[0120] The upper bottom portion 56 is provided with a drain port 53 which is a through hole penetrating in the up-down direction.

[0121] like Figure 4 , Figure 5As shown, the first evaporating dish 50 includes side surfaces 55 rising from the respective long sides of the upper bottom 56 and the lower bottom 54. The side surfaces 55 extend along the longitudinal direction of the first evaporating dish 50 and are provided over the entire longitudinal direction of the first evaporating dish 50. The upper ends of the side surfaces 55 form the long sides of the opening 51.

[0122] The first evaporating dish 50 is attached to the upper end portions of the legs 52 , and is thereby supported by the legs 52 at a position close to the other end of the drain pipe 48 from below.

[0123] In the present embodiment, the upper ends of the legs 52 are fixed to any position of the side surface 55 and attached to the first evaporating dish 50. In the first evaporating dish 50, the pair of legs 52 are arranged at one end of the lower bottom 54 in the longitudinal direction so as to sandwich the one end from the front-back direction. In the first evaporating dish 50, the pair of legs 52 are arranged at the other end of the lower bottom 54 in the longitudinal direction so as to sandwich the other end from the front-back direction.

[0124] The first evaporating dish 50 corresponds to the “second evaporating device” of the present disclosure.

[0125] like Figure 4 , Figure 5 As shown in the figure, the leg 52 is provided with an air guide plate 60. The air guide plate 60 is a member that is provided on the leg 52 to reinforce the leg 52 and the first evaporation dish 50 supported by the leg 52. The air guide plate 60 is a long plate-shaped member extending along the length direction of the first evaporation dish 50. Both ends of the air guide plate 60 are fixed to a pair of legs 52 installed on one side 55. In this embodiment, both ends of the air guide plate 60 are fixed to a pair of legs 52 installed on the rear side 55.

[0126] The upper end of the air guide plate 60 is arranged at a position in contact with the lower surface of the lower bottom portion 54. That is, the air guide plate 60 is arranged below the first evaporation dish 50. The lower end of the air guide plate 60 is arranged above the lower end of the leg portion 52. That is, the air guide plate 60 is arranged at a position separated from the bottom plate 24.

[0127] Figure 6 21 is a top view of the machine room 21. Figure 6 In the figure, for the convenience of explanation, the bottom plate 24, the first evaporation dish 50, the leg 52, the air guide plate 60 and the second evaporation dish 70 are shown, and other components are omitted. Figure 6 In FIG. 5 , for convenience of explanation, the first evaporating dish 50 is indicated by an imaginary line.

[0128] like Figure 6 As shown, the air guide plate 60 includes a first air guide surface 61 that forms a plane parallel to the side surface 55 .

[0129] The first wind guide surface 61 is provided with a second wind guide surface 63 that forms a plane extending in a direction different from the plane of the first wind guide surface 61 .

[0130] like Figure 5 As shown, in this embodiment, the second air guide surface 63 is formed by slit processing the end of the first air guide surface 61 located on the upper bottom 56 side. Specifically, the second air guide surface 63 is formed by bending the portion surrounded by the cutout in the plate thickness direction of the first air guide surface 61.

[0131] like Figure 6 As shown, in this embodiment, the second air guide surface 63 is bent toward the rear side when the first evaporation dish 50 is viewed from above. Therefore, the second air guide surface 63 extends in a direction different from that of the first air guide surface 61.

[0132] As described above, in this embodiment, the second wind guide surface 63 is formed integrally with the first wind guide surface 61. Figure 5 As shown, the second wind guide surface 63 forms a plane continuous with the first wind guide surface 61 along the length direction of the first wind guide surface 61 .

[0133] like Figure 3 As shown, in the machine room 21, the first evaporation dish 50 is disposed between the compressor 30, the condenser 32, and the blower 42. The first evaporation dish 50 is disposed such that the upper bottom 56 is located on the left and the lower bottom 54 is located on the right.

[0134] The first evaporating dish 50 is arranged such that the longitudinal direction extends in the left-right direction when the machine room unit 20 is viewed from above, and approaches the compressor 30 from the right to the left. In other words, the first evaporating dish 50 is arranged such that it moves away from the air blower 42 from the right to the left when the machine room unit 20 is viewed from above. That is, the first evaporating dish 50 is arranged to be inclined with respect to the condenser 32 and each air blower 42 when the machine room unit 20 is viewed from above.

[0135] Therefore, if Figure 3 , Figure 6 As shown, the side surface 55, the first air guide surface 61, and the second air guide surface 63 are arranged so as to be away from the surface on the back side of the condenser 32 and each blower 42 as they move from the right to the left. That is, the side surface 55, the first air guide surface 61, and the second air guide surface 63 extend in a manner that is inclined and crosses with respect to the direction orthogonal to the air supply direction A.

[0136] In the following description, a direction perpendicular to the air blowing direction A is referred to as a cross direction X. The cross direction X is a direction parallel to the skirting board 26 and the surface of the condenser 32 that faces the back surface.

[0137] In the present embodiment, the side surface 55 and the first air guide surface 61 are arranged so as to form an angle of about 10 degrees with the intersecting direction X.

[0138] In addition, the second air guide surface 63 is configured to be inclined relative to the condenser 32 at an angle greater than the side surface 55 and the first air guide surface 61 when the machine room unit 20 is viewed from above. In other words, in the air guide plate 60, the first air guide surface 61 and the second air guide surface 63 are opposite to the surface on the back side of the condenser 32 and each fan 42 at different inclination angles.

[0139] like Figure 4 As shown, the side surface 55 , the first air guide surface 61 , and the second air guide surface 63 are arranged so as to overlap with at least a portion of any air blower 42 when viewed from the front.

[0140] The first wind guide surface 61 is equivalent to the “first plane” of the present disclosure. The second wind guide surface 63 is equivalent to the “second plane” of the present disclosure.

[0141] like Figure 3 As shown, the middle part of the discharge pipe 33 is accommodated in the first evaporating dish 50. The discharge pipe 33 is a pipe that connects the discharge side of the compressor 30 and the condenser 32 in the refrigerant pipe 31. The discharge pipe 33 extending from the discharge side of the compressor 30 enters the inside of the first evaporating dish 50. The discharge pipe 33 entering the inside of the first evaporating dish 50 is led from one end to the other end at the upper surface of the bottom 54 below, and then folded back at the other end, and is led out from one end to the outside of the first evaporating dish 50, and connected to the condenser 32.

[0142] In addition, the middle portion of the discharge pipe 33 may be attached to the lower surface of the lower bottom portion 54. In this case, the discharge pipe 33 is led to the lower surface of the lower bottom portion 54 in the same manner as when the discharge pipe 33 is housed inside the first evaporating dish 50.

[0143] like Figure 3 As shown, the second evaporating dish 70 is stored in the machine room 21. The second evaporating dish 70 is an evaporating device that stores condensed water and evaporates it. The second evaporating dish 70 is formed into a long box shape when viewed from above. In this embodiment, the second evaporating dish 70 is arranged in the machine room 21 in such a way that the length direction is along the front-to-back direction. The second evaporating dish 70 has a length dimension in the length direction that is substantially the same as the length dimension in the front-to-back direction of the bottom plate 24.

[0144] In the machine room 21 , the second evaporating dish 70 is disposed at a position close to the left side surface of the unit main body 22 . The second evaporating dish 70 is disposed on the left side of the compressor 30 , the first evaporating dish 50 , and the condenser 32 in the machine room 21 .

[0145] Thus, the second evaporating dish 70 is arranged at a position deviated from the air blowing direction A. Specifically, the second evaporating dish 70 is arranged on the right side with respect to the air blowing direction A.

[0146] The second evaporating dish 70 has a predetermined depth dimension and has an opening 71 whose top surface is open. The upper end portion of the second evaporating dish 70 is disposed at substantially the same position as the lower end portion of the air guide plate 60 in the vertical direction.

[0147] A plurality of evaporation promoting members 72 are housed inside the second evaporating dish 70. The evaporation promoting members 72 are plate-shaped members formed of, for example, paper, fiber material, etc. The evaporation promoting members 72 are arranged so that their planes intersect the longitudinal direction of the second evaporating dish 70 and are arranged in a row along the longitudinal direction of the second evaporating dish 70. The upper end of the evaporation promoting member 72 protrudes above the second evaporating dish 70 through the opening 71.

[0148] At least a portion of the upper bottom portion 56 is disposed at a position overlapping with the second evaporating dish 70 in a plan view from above. Thus, the drain port 53 is disposed at a position overlapping with the second evaporating dish 70 in a plan view.

[0149] In this embodiment, if Figure 3 As shown, the first evaporation dish 50 overlaps with the second evaporation dish 70 at substantially the center in the longitudinal direction of the second evaporation dish 70 .

[0150] like Figure 4 As shown, the upper bottom portion 56 is disposed above the upper end of the evaporation promoting member 72 .

[0151] The second evaporating dish 70 is placed on rails or the like, for example, so as to be slidable in the front-rear direction.

[0152] like Figure 1 As shown, a partition plate 74 is provided on the front surface of the second evaporating dish 70. The partition plate 74 is provided with an opening 75 and a door 76 for closing the opening 75 in an openable and closable manner.

[0153] In the present embodiment, the user can pull out the second evaporating dish 70 from the machine room 21 by removing the skirting board 26 and opening the door 76 .

[0154] In addition, the second evaporating dish 70 is not limited to being pulled out from the front surface of the machine room unit 20, and may be configured to be pulled out from any one of the left and right side surfaces or the back surface. In addition, the second evaporating dish 70 may be pulled out along the length direction of the second evaporating dish 70. In addition, for example, the second evaporating dish 70 may also be pulled out in a direction intersecting the length direction.

[0155] The second evaporating dish 70 corresponds to the “first evaporating device” of the present disclosure.

[0156] [1-2. Action]

[0157] [1-2-1. Cooling of the showroom]

[0158] Next, the operation of the showcase 1 will be described.

[0159] When the showcase 1 is in operation, the refrigerant is discharged from the compressor 30, condensed in the condenser 32, and then supplied to the evaporator 34. The refrigerant evaporated in the evaporator 34 flows back to the compressor 30.

[0160] The air in the duct space 13 is sent to the evaporator 34 by the blower 40. After being cooled by the evaporator 34, the sent air is blown out as cold air from the blow-out port 15 to the display room 11 through the duct space 13. The inside of the display room 11 is cooled to a predetermined temperature by the cold air. Furthermore, the cold air that has cooled the inside of the display room 11 flows into the duct space 13 again from the suction port 17.

[0161] In this way, the cold air generated in the duct space 13 circulates inside the showcase 1 .

[0162] The flow of cold air blown forward and downward from the blowout port 15 and sucked into the suction port 17 forms an air curtain flowing along the housing opening 9. In the showcase 1, the air curtain thermally isolates the external air outside the housing body 10 from the air inside the display room 11, and the temperature rise inside the display room 11 caused by the external air is reduced.

[0163] [1-2-2. Evaporation of condensation water]

[0164] In the duct space 13 , condensed water called drain water is generated as cold air is generated. The condensed water is sent to the machine room 21 through the drain pipe 48 and stored in the first evaporation dish 50 .

[0165] The first evaporation dish 50 accommodates a middle portion of the discharge pipe 33. The discharge pipe 33 allows high-temperature and high-pressure refrigerant discharged from the compressor 30 to flow. As a result, at least a portion of the condensed water stored in the first evaporation dish 50 evaporates and is heated to a temperature range that allows easy evaporation.

[0166] When a predetermined amount of condensed water is stored in the first evaporation dish 50, the condensed water flows out to the second evaporation dish 70 through the drain port 53. The condensed water stored in the second evaporation dish 70 is absorbed by the evaporation promoting member 72. The other condensed water absorbed by the evaporation promoting member 72 is diffused to the entire evaporation promoting member 72. Thus, the condensed water can be evaporated by the transpiration of the evaporation promoting member 72.

[0167] Each blower 42 sends the air having exchanged heat with the condenser 32 to the rear side of the machine room 21. The first evaporation dish 50 and the air guide plate 60 are arranged on the rear side of the blower 42. Therefore, the air sent from the blower 42 contacts the side surface 55 located on the front side of the machine room 21, the first air guide surface 61, and the second air guide surface 63.

[0168] This air is the air that has undergone heat exchange with the high-temperature and high-pressure refrigerant flowing through the condenser 32 . Therefore, the condensed water stored in the first evaporation dish 50 is heated by this air that has come into contact with the side surface 55 .

[0169] As described above, the lower end of the air guide plate 60 provided below the first evaporation dish 50 is separated from the bottom plate 24. Thus, part of the air sent from the blower 42 passes between the air guide plate 60 and the bottom plate 24 and is blown toward the compressor 30. Therefore, the compressor 30 is cooled by the air.

[0170] like Figure 3 , Figure 5 As shown, the first evaporation dish 50 and the air guide plate 60 are arranged so as to be away from the respective blowers 42 as they approach the second evaporation dish 70 in the respective longitudinal directions when the machine room unit 20 is viewed from above.

[0171] The air contacting the side surface 55 is guided along the surface of the side surface 55 in the direction of the length of the side surface 55 and away from the blower 42. Figure 5 , Figure 6 As shown, the air flows in the air supply direction B which is the direction toward the left of the machine room 21. The air supply direction B is a direction that forms an angle substantially the same as the predetermined angle formed by the first evaporation dish 50 with respect to the intersecting direction X. The air flowing in the air supply direction B is directed toward the left end of the first evaporation dish 50.

[0172] The air contacting the first air guide surface 61 is guided along the surface of the first air guide surface 61 in the longitudinal direction of the first air guide surface 61 and in the direction away from the blower 42. Specifically, the air flows in the direction toward the left of the machine room 21, that is, the air supply direction C. The air supply direction C is a direction that forms an angle substantially the same as the predetermined angle formed by the first evaporation dish 50 with respect to the cross direction X, and is substantially parallel to the air supply direction B. The air flowing along the air supply direction B is directed toward the left end of the first evaporation dish 50.

[0173] like Figure 3As shown, the left end of the first evaporation dish 50 overlaps the second evaporation dish 70 at the approximate center in the longitudinal direction of the second evaporation dish 70. Therefore, the air flowing along the air supply direction B and the air supply direction C flows to the approximate center of the second evaporation dish 70. The air is blown to the evaporation promotion member 72 and flows between the evaporation promotion members 72. As a result, the evaporation effect of the evaporation promotion member 72 is promoted, and the evaporation of the condensation water stored in the second evaporation dish 70 is promoted.

[0174] That is, the first evaporating dish 50 and the air guide plate 60 function as an air guide member that guides the air sent out by the blower 42 to the second evaporating dish 70 .

[0175] The air contacting the second air guide surface 63 is guided along the surface of the second air guide surface 63 in the length direction of the second air guide surface 63 and away from the blower 42. Figure 5 , Figure 6 As shown, the air flows in the direction toward the left of the machine room 21, that is, in the air supply direction C'.

[0176] As described above, when the machine room unit 20 is viewed from above, the second air guide surface 63 forms an inclination angle different from that of the side surface 55 and the first air guide surface 61 with respect to the intersecting direction X. Therefore, the air supply direction C' forms an obtuse angle with respect to the intersecting direction X compared to the predetermined angle formed by the first evaporation dish 50, and is a direction toward the rear side of the air supply direction B and the air supply direction C.

[0177] Part of the air that contacts the first air guide surface 61 and flows along the air supply direction C deviates from the air supply direction C at the left end of the air guide plate 60 and flows along the surface of the second air guide surface 63. That is, part of the air that flows along the air supply direction C flows along the air supply direction C′.

[0178] The air flowing along the air supply direction C' is directed toward the left end of the first evaporation dish 50. The air flowing along the air supply direction C' is blown to the evaporation promotion member 72 located behind the approximate center of the second evaporation dish 70 at the left end of the first evaporation dish 50, and flows between the evaporation promotion members 72. Thus, the evaporation of the evaporation promotion member 72 is promoted, and the evaporation of the condensed water stored in the second evaporation dish 70 is promoted.

[0179] Thus, in the machine room 21, the air sent from the air blower 42 is directed to the left along the air supply direction B, the air supply direction C, and the air supply direction C', so that the air can be sent to a wider range in the length direction of the second evaporation dish 70. Therefore, in the machine room 21, the air is blown to more evaporation promotion members 72, and the evaporation of the condensed water stored in the second evaporation dish 70 is further promoted.

[0180] The air guided to the second evaporation dish 70 is exhausted to the outside of the showcase 1 through the exhaust space 5 .

[0181] [1-3. Effects, etc.]

[0182] As described above, in this embodiment, the showcase 1 includes the condenser 32, the blower 42 that blows air to the condenser 32, the first evaporation dish 50 and the second evaporation dish 70 that store and evaporate condensed water, and the air guide plate 60. The first evaporation dish 50 and the air guide plate 60 are arranged to be inclined with respect to the blower 42, and guide the air sent from the blower 42 to the second evaporation dish 70.

[0183] Thus, in the showcase 1 , air can be sent to the second evaporation dish 70 disposed at a position deviated from the air blowing direction A of the air blower 42 . Therefore, in the showcase 1 , evaporation of condensed water stored in the second evaporation dish 70 can be promoted.

[0184] As in the present embodiment, the air guide plate 60 may be disposed below the first evaporating dish 50 .

[0185] Thus, the air guide plate 60 is disposed at a position overlapping with the first evaporation dish 50 in a plan view of the machinery room unit 20. Therefore, in the machinery room 21, it is possible to save space for arranging the air guide member.

[0186] As in the present embodiment, the air guide plate 60 may be a reinforcement member for reinforcing the first evaporating dish 50 .

[0187] Thus, the air guide plate 60 can reinforce the first evaporation dish 50 and guide the air sent from the blower 42 to the second evaporation dish 70. Therefore, the air guide plate 60 can reinforce the first evaporation dish 50 and promote evaporation of condensed water stored in the second evaporation dish 70.

[0188] As in the present embodiment, the air guide plate 60 may include a first air guide surface 61 and a second air guide surface 63 that face the second evaporation dish 70 and the blower 42 and extend in directions different from each other.

[0189] Thus, in the showcase 1 , air can be sent over a wider range to the second evaporating dish 70 disposed at a position deviated from the air blowing direction A of the blower 42 . Therefore, in the showcase 1 , evaporation of condensed water stored in the second evaporating dish 70 can be promoted.

[0190] As in the present embodiment, the second evaporating dish 70 may be disposed laterally in the direction in which the air sent from the blower 42 flows.

[0191] Thus, in the showcase 1 , the second evaporating dish 70 can be disposed at a position deviated from the air blowing direction A of the blower 42 . Therefore, in the showcase 1 , the second evaporating dish 70 can be disposed at an appropriate position according to the layout of the machine room 21 .

[0192] As in the present embodiment, the machine room unit 20 that accommodates the condenser 32 , the blower 42 , and the second evaporating dish 70 may be provided, and the second evaporating dish 70 may be provided so as to be drawn out from the front of the machine room unit 20 to the outside of the machine room unit 20 .

[0193] Thus, in the showcase 1, the second evaporating dish 70 can be easily taken out from the machine room 21. Therefore, in the showcase 1, the maintenance of the second evaporating dish 70 can be easily performed.
