  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(1st Embodiment)
FIG. 1 is a perspective view of a showcase 1 according to the first embodiment. The showcase 1 has a display room R for displaying products such as food or beverage. A plurality of display shelves 11 are arranged inside the display room R. A deck pan 12 is arranged at the bottom of the display room R. Goods are displayed on the display shelf 11 and the deck pan 12.

  The display room R is open at least on the front side. The display room R is accessible from the front side. That is, a person facing the showcase 1, such as a customer or a worker, can access products displayed in the display room R from the front side of the showcase 1.

  The display room R of the showcase 1 according to the present embodiment is also open on the left and right sides, and is accessible from the left and right sides. Of course, the display room R may be accessible only from the front side. Also, the showcase 1 may have a door or goodwill (not shown) on the front side, and the display room R may be accessible from the front side by opening the door or goodwill.

  Here, the description “left or right” in the description of the present embodiment means the left or right of the showcase itself. That is, it means the left side or the right side when the showcase 1 is viewed from the rear side of the showcase 1.

  On the right side of the showcase 1, a right side plate member 13 constituting the right side surface of the showcase 1 is arranged. On the left side of the showcase 1, a left side plate member 14 constituting the left side surface of the showcase 1 is arranged.

  On the upper part of the showcase 1, a cover 15 for covering the machinery is arranged. The inside of the cover 15 is an upper machine room. In the upper machine room, for example, a compressor (not shown) constituting a refrigeration cycle is arranged.

  A machine room is arranged below the showcase 1, specifically, below the deck pan 12. A front plate member 16 is disposed on the front side of the machine room. The front side plate member 16 is arranged below the display room R, and forms the front surface of the showcase 1. The front side plate member 16 can be easily attached to and detached from the showcase 1 main body by an attachment / detachment mechanism such as a magnet.

  The front plate member 16 has a front ventilation section 17. The front side ventilation part 17 is constituted by a plurality of openings formed by pressing a front side plate member 16 made of a steel plate. The front ventilation section 17 may have any structure as long as air can flow between the inside and the outside of the machine room. For example, the front ventilation section 17 may be a metal net. , A resin or paper filter.

  FIG. 2 is a plan view of the inside of the machine room. FIG. 3 is a perspective view of the inside of the machine room. FIG. 4 is a perspective view of the drain evaporator 30 and the drain heater 50.

  A bottom plate 18 is disposed at the bottom of the machine room. The bottom plate 18 is fixed to the showcase 1 main body. A guide rail 19 is attached to the upper surface of the bottom plate 18. The guide rail 19 will be described later in detail.

  On the bottom plate 18 and on the right side, a condenser 20 is arranged. On the left side of the condenser 20, a drain evaporator 30 is arranged. A blower 40 is arranged between the condenser 20 and the drain evaporator 30. A drain heating device 50 is arranged between the blower 40 and the drain evaporator 30. Further, a flow straightening plate 60 is disposed between the blower 40 and the drain heating device 50.

  The condenser 20 is a heat exchanger that exchanges heat between the refrigerant, which has been heated by the compressor and has a high temperature, and air flowing around the refrigerant to condense the refrigerant. Conversely, the condenser 20 heats the air flowing around it.

  The condenser 20 is arranged so as to be more distant from the right end of the showcase 1, that is, the right side plate member 13 (see FIG. 1) as the front side. The condenser 20 is fixed to the bottom plate 18.

  The drain evaporating device 30 is a device that evaporates drain (condensed water and defrosted water) generated around the display room R in which products are displayed in a refrigerated or frozen state. The drain evaporator 30 includes a drain plate 31 for storing drain and a plurality of evaporation promoting members 32 for absorbing and evaporating the drain. The evaporation promoting member 32 is disposed inside the drain plate 31 with the upper side exposed. The evaporation promoting member 32 is a plate-like member made of, for example, paper.

  Similarly to the condenser 20, the drain evaporator 30 is disposed so as to be further away from the right end of the showcase 1, that is, the right side plate member 13 (see FIG. 1). In other words, the extending direction of the drain evaporator 30 and the extending direction of the condenser 20 are parallel to each other, and are inclined with respect to the extending direction of the front plate member 16.

  The blower 40 includes a plurality of DC fans arranged in a line. The blower 40 sucks air from the condenser 20 side and discharges the air toward the drain evaporator 30 side. That is, the blower 40 creates a flow of air from the condenser 20 to the drain evaporator 30. In addition, if such a flow can be created, the arrangement position of the blower 40 may be anywhere. The blower 40 is fixed on the bottom plate 18.

  The drain heating device 50 is a member that stores and heats the drain generated in the showcase 1 to evaporate part of the drain and promote drain evaporation in the drain evaporator 30.

  The drain heating device 50 includes a heating drain plate 51 and a refrigerant pipe 52. The heating drain tray 51 is arranged below a gutter (not shown) for collecting drain generated around the display room R, and stores the drain collected by the gutter. Inside the heating drain tray 51, a refrigerant pipe 52 through which a refrigerant circulating in a refrigeration cycle constituted by the compressor, the condenser 20, and the like passes is disposed. The refrigerant passing through the refrigerant pipe 52 is a refrigerant that is discharged from the compressor and before flowing into the condenser 20, and has a high temperature.

  The drain stored in the heating drain tray 51 is heated by the refrigerant pipe 52 and partially evaporates. Further, the drain stored in the heating drain tray 51 overflows toward the drain tray 31 as the stored amount increases. At this time, since the drain is heated, the drain evaporator 30 is in a state of being more easily evaporated.

  The heating drain plate 51 and the refrigerant pipe 52 are fixed on the bottom plate 18.

  The heating drain tray 51 and the guide rail 19 are arranged so as to sandwich the drain tray 31. The extending direction of the heating drain plate 51 and the extending direction of the guide rail 19 are parallel to the extending direction of the drain plate 31. Therefore, when the drain tray 31 is pulled out to the front side as described later, the heating drain tray 51 and the guide rail 19 guide the drain tray 31 in the pulling-out direction.

  The current plate 60 is a member for adjusting the flow of air from the condenser 20 to the drain evaporator 30 so that the air flows around the evaporation promoting member 32 more effectively.

  The current plate 60 includes a first current plate 61 on the front side and a second current plate 62 on the rear side. The first rectifying plate 61 and the second rectifying plate 62 have different horizontal surfaces, that is, different inclination angles with respect to the bottom plate 18. Specifically, the inclination angle of the first current plate 61 with respect to the horizontal plane is larger than that of the second current plate 62.

  The following phenomena occur inside the machine room in which the devices are arranged as described above.

  First, the drain collected by the gutter is stored inside the heating drain tray 51. This drain is heated by the refrigerant pipe 52 and a part of the drain evaporates. The drain that has not evaporated overflows from the heating drain pan 51 to the drain pan 31.

  The drain in the drain plate 31 is absorbed by the evaporation promoting member 32. That is, the evaporation promoting member 32 is in a state where the inside thereof is filled with the drain.

  The operation of the blower 40 generates a flow of air in the machine room. Air enters the machine room from the outside through the front ventilation part 17 (see FIG. 1). This air flows around the condenser 20 and is heated. Thereafter, the air passes through the blower 40, is rectified by the rectifying plate 60, and reaches the drain evaporator 30. At this time, the air flows around the evaporation promoting member 32, evaporates the drain filled in the evaporation promoting member 32, and is discharged outside from the rear of the showcase 1 along with the evaporated drain.

  On the upstream side of the condenser 20, a triangular or trapezoidal space in plan view, which is at least partially surrounded by the front plate member 16 (see FIG. 1), the right plate member 13 (see FIG. 1), and the condenser 20. Is formed. Therefore, the blower 40 can smoothly suck in air from the outside via the front ventilation section 17. In other words, by arranging the condenser 20 and the drain evaporator 30 and the like in an inclined state with respect to the front side plate member 16, a sufficiently large space can be secured on the right side of the condenser 20, and the intake efficiency is improved. Can be raised.

  The front ventilation section 17 may be provided anywhere as long as it is on the right side of the condenser 20, that is, on the upstream side of the stream of air, and may be provided on the entire front plate member 16. It may be provided only in a portion located on the right side of the container 20.

  Further, a triangular or trapezoidal space in a plan view, which is at least partially surrounded by the left side plate member 14 (see FIG. 1) and the drain evaporator 30, is formed downstream of the drain evaporator 30. Therefore, the blower 40 smoothly moves the air downstream of the drain evaporator 30, specifically, through the rear opening without retaining the air between the drain evaporator 30 and the left side plate member 14. Can be discharged to the outside. In other words, by arranging the condenser 20 and the drain evaporator 30 and the like in an inclined state with respect to the front plate member 16, a sufficiently wide space can be secured on the left side of the drain evaporator 30, and the exhaust efficiency can be improved. Can be raised.

  The first rectifying plate 61 disposed on the front side has a larger inclination angle with respect to the horizontal plane than the second rectifying plate 62 disposed on the rear side. Conversely, the second rectifying plate 62 disposed on the rear side has a smaller inclination angle with respect to the horizontal plane than the first rectifying plate 61 disposed on the front side. This prevents the air sucked into the machine room from the front side through the front ventilation part 17 from flowing in the machine room, so that the air flows more in the front part and flows less in the rear part. can do. That is, the air can be more efficiently flown, heated, and the drain can be evaporated.

  5A, which shows the state of the machine room before the drain evaporator 30 is pulled out, there is no member other than the front plate member 16 on the front side of the drain evaporator 30. Therefore, the drain evaporator 30 can be easily pulled out to the front side of the showcase 1 independently of other devices, for example, the condenser 20, simply by removing the front plate member 16 from the showcase 1. The state of the machine room after the drain evaporator 30 is drawn out is shown in FIG. 5B.

  Therefore, in the showcase 1 according to the present embodiment, only the drain evaporator 30 is pulled out to the front side, and maintenance of the drain evaporator 30 can be performed very easily.

  Further, a slight gap is formed between the drain evaporator 30 and the guide rail 19 and the heating drain pan 51. Therefore, after being drawn out to some extent along the guide rail 19 and the heating drain pan 51, the drain evaporator 30 can be drawn out in a direction parallel to the left side plate member 14 (see FIG. 1). Therefore, even if the left side of the showcase 1 is in contact with the wall surface of the room where the showcase 1 is installed, the drain evaporator 30 can be pulled out to the front.

(Modification)
Note that the arrangement of the devices in the machine room may be symmetrical to those described above. That is, the condenser 20 may be arranged on the left side of the machine room, and the drain evaporator 30 may be arranged on the right side of the condenser 20.

  In this case, the condenser 20, the blower 40, the flow regulating plate 60, the drain heating device 50, the drain evaporator 30, and the guide rail 19 are arranged in this order from the left, and the condenser 20 is more distant from the left end of the showcase 1 toward the front. Are arranged as follows. In this case, a triangular or trapezoidal space in a plan view, which is at least partially surrounded by the front plate member 16 (see FIG. 1), the left plate member 14 (see FIG. 1), and the condenser 20, is formed. . Further, in this case, a triangular or trapezoidal space in a plan view, which is at least partially surrounded by the right side plate member 13 (see FIG. 1) and the drain evaporator 30, is formed.

  Even if the devices are arranged in this manner, the same effects as those of the showcase 1 described with reference to FIGS. 1 to 5B can be obtained.

  Further, the blower 40 may be disposed on the bottom plate 18 so as to be able to be drawn out to the front side independently of the condenser 20 and the drain evaporator 30. In this case, only the blower 40 is pulled out to the front side, and maintenance of the blower 40 can be performed very easily.

(Second embodiment)
Next, a showcase 2 according to a second embodiment will be described with reference to FIGS. FIG. 6 is a perspective view of the showcase 2 according to the second embodiment. FIG. 7 is a diagram illustrating an example of the arrangement of the showcase 2 according to the second embodiment.

  Also in the description of the present embodiment, the description “left side” or “right side” means the left side or right side of the showcase itself. That is, it means the left side or the right side when viewing the showcase 2 from the rear side of the showcase 2.

  As shown in FIG. 6, the right side plate member 13 of the showcase 2 according to the present embodiment has a right side ventilation portion 13a. The right ventilation section 13a is located below the display room R. That is, air can flow into the machine room from the outside via the right ventilation section 13a. Other configurations are the same as those of the showcase 1 according to the first embodiment.

  The showcase 2 according to the present embodiment can be disposed adjacent to the left side of the conventional showcase 7 as shown in FIG. The conventional showcase 7 is a showcase having a leg below the display room R but having no machine room in which machines are arranged. That is, at the lowermost part of the conventional showcase 7, a space that allows ventilation with the outside is widened. Note that a side plate 70 is disposed on the right side of the conventional showcase 7, and no plate-shaped member is disposed on the left side.

  When arranged as shown in FIG. 7, air can flow from the right side to the left side without any trouble in the machine room of the showcase 2 according to the present embodiment. In this case, since the air flows linearly from the right side to the left side, the intake efficiency is further increased as compared with the showcase 1 according to the first embodiment. As a result, the amount of heat released from the condenser increases, and therefore, the energy saving effect also improves.

(Modification)
When the left side plate member 14 constituting the left side surface of the showcase 2 has a left side ventilation portion (not shown) located below the display room R, the condenser 20 is disposed on the left side of the machine room. In addition, the drain evaporator 30 may be arranged on the right side of the condenser 20. In this case, the showcase 2 according to the present embodiment can be arranged adjacent to the right side of the conventional showcase 7. However, in this case, the side plate 70 of the conventional showcase 7 needs to be arranged on the left side of the conventional showcase 7.

  Further, in the present embodiment, air is sucked into the machine room from the outside via the right ventilation portion 13a of the right plate member 13 or the left ventilation portion (not shown) of the left plate member 14. Therefore, the condenser 20 and the drain evaporator 30 do not necessarily have to be arranged at an angle. That is, in the showcase 2 according to the present embodiment, the extending direction of the condenser 20 and the extending direction of the drain evaporator 30 are orthogonal to the extending direction of the front plate member 16 (see FIG. 1). May be. In other words, the condenser 20, the drain evaporator 30, the blower 40, the drain heater 50, and the rectifying plate 60 may extend in a direction parallel to the right plate 13 and the left plate 14.

  Even if the devices are arranged in this way, the blower 40 can generate an airflow from the condenser 20 to the drain evaporator 30. In addition, the air flow can cause the drain to evaporate in the drain evaporator 30. Further, the drain evaporator 30 can be pulled out to the front side independently of the condenser 20, and maintenance can be performed very easily.

  Note that the present invention is not limited to what has been specifically described, and it is needless to say that the specific configurations described in the embodiments can be variously changed or combined.

  The present invention is widely applicable to showcases.
