(Effects of Example)
Next, the operation of the refrigerated showcase according to the above-described embodiment will be described.
When the fan motor 16 is removed from the machine room 13 during maintenance of the cooling mechanism 17, the top cover 26 and the side panel 23 are removed from the refrigerated showcase 10 to release the fixing of the side frame 21 to the bottom 20 and the top frame 22. Both the frames 21 and 22 are integrally removed by releasing the fixing to the partition wall 12. By removing the side panel 23 and the side frame 21, a side opening 27 is opened to the side of the machine room 13 (see FIG. 1). By opening the side opening 27, the screw 43 fixing the shroud 34 to the condenser 15 is exposed to the side opening. Accordingly, the screw 43 is loosened and the second extending portion 30a of the condenser 15 and the second flange portion 42 of the shroud 34 are released, and then the shroud 34 is moved to the side opening side. Each of the projecting pieces 41 a in the first flange portion 41 of the shroud 34 is pulled out from the corresponding hole 29 b in the first extending portion 29 a of the condenser 15. It is taken out outdoors (see FIG. 3). When the protruding piece 41a is pulled out from the punching hole 29b, the shroud 34 is slightly inclined forward so that the bent piece 45a of the positioning piece 45 is pulled out of the positioning hole 44 of the shroud 34.

  Next, when the shroud 34 to which the fan motor 16 is attached is attached and fixed to the condenser 15 in the machine room, the shroud 34 is placed from the side opening 27 so that the first flange portion 41 faces the back side. Insert into chamber 13. At this time, the main body plate 37 is inserted in a slightly inclined posture so that the main body plate 37 faces the front side of the positioning piece 45 of the unit base 28, and each protruding piece 41a of the first flange portion 41 is inserted into the corresponding extension of the first extending portion 29a. It inserts into the hole 29b from the side. At this time, the bent piece 45 a of the positioning piece 45 is also inserted into the positioning hole 44 of the main body plate 37 from the rear side. The first flange portion 41 is in contact with the side surface of the first extension portion 29 a from the side, and the positioning piece 45 in which the bending piece 45 a is inserted into the positioning hole 44 is the rear surface of the main body plate 37. The screw 43 inserted from the outside into the through hole 42a of the second flange portion 42 facing the outer side of the second extending portion 30a in the state of contact with the second extending portion 30a (see FIG. 7) The shroud 34 is attached and fixed to the condenser 15 by being screwed into 30b.

  As described above, the fan motor 16 is removed from and attached to the condenser 15 installed in the machine room 13 by releasing the fixing of the shroud 34 and the condenser 15 by the single screw 43 exposed to the side opening. In this state, it is only necessary to pull out or insert the fan motor 16 from the side opening 27 of the machine room 13 together with the shroud 34, so that the maintainability is improved. That is, even if the gap between the condenser 15 and the compressor 14 is small and it is difficult to insert a hand from the side opening 27 to the back side (storage chamber side), the fan motor 16 ( The shroud 34) can be easily removed and attached. In addition, the condenser 15 and the shroud 34 can be fixed by the single screw 43 exposed to the side opening, so that the number of parts relating to the fixing is small and the cost can be reduced. Further, the shroud 34 is only fixed to the condenser 15 via the screw 43 on the side opening portion side, but the positioning piece 45 of the unit base 28 abuts the main body plate 37 from the rear side, Since the intermediate part of both flange parts 41 and 42 supported by both extension parts 29a and 30a of the condenser 15 in the main body plate 37 is held in a stretched state on the front side, the shroud 34 is stably held. .

  With the top frame 22 attached to the upper end portion of the side frame 21, the lower end portion of the side frame 21 is attached to the bottom portion 20 and the extended end portion of the top frame 22 is attached to the upper end portion of the partition wall 12. At this time, the horizontal plate portion 24c of the exterior panel 24 disposed on the top frame 22 contacts the second bent portion 40b of the support portion 40 in the flange portion 39 of the shroud 34 from above as shown in FIG. Supported in contact. Further, the rear end of the second bent portion 40b comes into contact with the inner surface of the guide portion 24d of the exterior panel 24 from the front side, whereby the vertical portion 24b of the exterior panel 24 is positioned.

  Since the exterior panel 24 is supported by the support portion 40 of the shroud 34 as described above, when the operation button 47a of the power switch 47 disposed on the exterior panel 24 is pressed, its force Can be supported by the shroud 34 via the second bent portion 40b that contacts the inner surface of the guide portion 24d. That is, it is not necessary to set the strength of the exterior panel 24 higher than necessary in order to withstand the force applied when operating the operation button 47a of the power switch 47, and the exterior panel 24 is made of resin without using a thick sheet metal. It can be handled with products, and the cost can be kept low. Since the support portion 40 of the shroud 34 faces the flow path of the air sucked from the louver 25, the support portion 40 does not become high temperature due to the heat of the condenser 15, and the heat effect on the power switch 47 is affected. Is suppressed.

  A rear opening 46 defined between the bottom 20 and the exterior panel 24 is closed by a louver 25 attached between the bottom 20 and the exterior panel 24. As for the louver 25, as shown in FIG. 8, the upper insertion portion 25b is inserted from below into a guide groove 48 defined between the guide portion 24d of the exterior panel 24 and the first bent portion 40a of the shroud 34. The lower engaging portion 25c of the louver 25 is attached by engaging with the defining portion 20a of the bottom portion 20.

  Since the guide groove 48 for inserting the upper insertion portion 25b of the louver 25 is formed by using the flange portion 39 of the shroud 34 for preventing a short cycle of air in the upper portion of the condenser 15, the guide groove 48 is provided. A dedicated member can be omitted. Further, the louver 25 is properly positioned on the air suction side of the condenser 15 by inserting the upper insertion portion 25b into the guide groove 48 formed by the flange portion 39 for preventing a short cycle.

  When transporting the refrigerated showcase 10 or the like, especially in the case where the gap between the compressor 14 and the fan motor 16 is small, the compressor 14 is fanned by vibrations or the like applied when it is handled in a rough manner during transportation. The motor 16 may be contacted. In this case, in the fan motor 16 of the embodiment, the fixing frame 33 is fixed to the shroud 34 at two diagonal fixing bosses 35 with screws, and the shroud 34 body plate 37 is fixed. Since the mounting frame 33 is separated from the main body (portion other than the fixing boss 35), the mounting frame 33 is allowed to swing back and forth around one diagonal line as an axis. Therefore, when the compressor 14 comes into contact with the fan motor 16, the mounting frame 33 can be swung to relieve (release) the impact force, and the fan motor 16 can be damaged without applying excessive force. Can be prevented. Further, since the fixing bosses 35 and 35 of the mounting frame 33 are provided at the corners located at one diagonal, the spacing between the both fixing bosses 35 and 35 can be increased, and the fan motor 16 is impacted. When is added, the mounting frame 33 can be easily swung to suitably reduce the impact force. Moreover, immediately before the fixing portions of the fixing bosses 35, 35 to the main body plate 37 are damaged, the main body of the mounting frame 33 and the non-fixing bosses 36, 36 come into contact with the main body plate 37 and the inner edge of the large-diameter through hole 37c. By restricting the swinging, the fixing portion is prevented from being damaged.
