[Operation of Example 1]
Next, the operation of the ice storage 80 according to the first embodiment will be described. First, the flow of condensed water generated in the slide doors 64 and 64 will be described with reference to FIG. Condensed water that flows down along the sliding doors 64 and 64 and accumulates in the lower groove 54B of the lower rail portion 52B passes through the drain hole 62 formed in the partition 50a at the rearmost portion, and passes through the front end of the partition 50a and the slope 68. It flows down to the first receiving passage 84 provided between the edge 70b. Condensed water that is guided to the left and right along the first receiving passage 84 and reaches the left and right ends of the first receiving passage 84 passes along the front end edge 70 b and the side end edge 70 c of the slope 68. 86. Condensed water flowing down the second receiving passage 86 along the passage 86 passes through the passage port 88 provided between the weir portion 44 and the slope 68 and is guided to the drainage passage 82.

Condensed water that has reached the extended end 42a of the ridge portion 42 falls to the surface of the bank portion 22 on the ice storage chamber 14 side, and drain pipe (both shown) from a drain outlet provided at the bottom of the ice storage chamber 14. To the outside of the warehouse. In addition, since the collar part 42 is extended from the top part 22a of the bank part 22 to the back, the dew condensation water which fell from the extension end part 42a of the collar part 42 is from the lower edge of the front opening part 12A in the said housing | casing 12. There is no leakage outside the warehouse.

  That is, a drainage passage formed between the saddle portion 42 and the slope 68 is provided below the slope 68 by providing a flange portion 42 that is inclined obliquely downward from the lower opening edge 36B of the rectangular opening portion 34 toward the ice storage chamber 14. Since the condensed water accumulated in the lower rail portion 52 </ b> B is guided to 82, the condensed water passes under the slope 68. Therefore, since dew condensation water does not splash on the ice deposited on the slope 68, melting of the ice can be suppressed. Further, since the collar portion 42 is integrally formed on the door back panel 40 and the drainage passage 82 is formed by the collar portion 42 and the slope 68, it is exclusively used for draining the condensed water accumulated in the lower rail portion 52B. Therefore, there is no need to use another member, and the cost associated with the increase in the number of parts does not occur.

  Further, since the first receiving passage 84 that receives the condensed water accumulated in the lower rail portion 52B is provided between the front edge 70b of the slope 68 and the rearmost partition 50a, the condensed water accumulated in the lower rail portion 52B. Can be smoothly guided along the first receiving passage 84. Further, since the second receiving passage 86 is provided which communicates with the left and right ends of the first receiving passage 84 and extends along the side edge 70c of the slope 68, the left and right ends of the first receiving passage 84 are reached. Condensed water can be smoothly guided along the second receiving passage 86. Since the dew condensation water in the second receiving passage 86 is guided from the passage port 88 to the drainage passage 82 along the side edge 70c of the slope 68, the dew condensation water in the second reception passage 86 is naturally drained. Up to 82. That is, the condensed water accumulated in the lower rail portion 52 </ b> B passes through the first receiving passage 84, the second receiving passage 86 and the passage port 88 along the end edges 70 b and 70 c of the slope 68, and reliably reaches the drain passage 82. Can guide you. In this way, the condensed water accumulated in the lower rail portion 52B is prevented from flowing on the slope 68.

  Here, as shown in FIG. 10, in the conventional ice storage 10, there is a problem that the dew condensation water reaching the left and right ends of the opening lower edge 36 </ b> B in the rectangular opening 34 flows out to the outside of the rectangular opening 34. . Condensed water that has flowed out of the rectangular opening 34 leaks out of the cabinet through the slope 68 of the door back panel 40 and the inner wall of the ice storage chamber 14 (indicated by a two-dot chain line in FIG. 10). (See arrow in FIG. 10). On the other hand, in the ice storage 80 according to the first embodiment, as shown in FIG. 1B, the weir portions 44 are provided at the left and right end portions of the opening lower edge 36B in the rectangular opening 34, so that the second Condensed water flowing down the left and right outer end portions in the receiving passage 86 is guided along the dam portion 44 to the left and right inner sides. The condensed water guided inward by the dam portion 44 flows down to the drainage passage 82 through the passage port 88 provided between the dam portion 44 and the slope 68. That is, by providing the weir portion 44, it is possible to prevent the dew condensation water reaching the left and right ends of the opening lower edge 36B in the rectangular opening 34 from flowing out to the outside of the rectangular opening 34.

[Example 2]
Next, a second embodiment will be described with reference to FIG. As shown in FIG. 5, the ice storage 80 according to the first embodiment is configured to guide the dew condensation water to the drainage passage 82 through the passage port 88 between the weir portion 44 and the slope 68. On the other hand, the ice storage 90 according to the second embodiment shown in FIG. 6 is configured to guide the condensed water to the drainage passage 82 also from the notch 92 formed in the slope 68. In addition, in the ice storage 90 of Example 2, the same code | symbol shall be attached | subjected about the same member as a prior art example and Example 1. FIG.

  As shown in FIG. 6, in the second embodiment, a notch for guiding the condensed water in the first receiving passage 84 to the drainage passage 82 is formed at the front end edge (end edge) 70 b facing the first receiving passage 84 in the slope 68. 92 is formed. The notch 92 is formed from the front end edge 70b of the slope 68 to the rear side of the opening lower edge 36B where the upper end of the flange portion 42 is located in the rectangular opening 34. As in the first embodiment, the ice storage 90 can also guide the dew condensation water to the drainage passage 82 from the passage port 88 provided between the weir portion 44 and the side edge 70c of the slope 68. Yes.

[Operation of Example 2]
The condensed water in the first receiving passage 84 enters the notch 92 along the front end edge 70b of the slope 68, and flows down the upper surface of the extending portion 58B in the lower frame 48B along the notch 92. The condensed water that has reached the upper end of the flange 42 from the rear end of the extending portion 58B flows down obliquely downward into the ice storage chamber 14 along the upper surface of the flange 42. As in the first embodiment, the condensed water that has reached the extended end portion 42 a of the ridge portion 42 is dropped on the surface of the bank portion 22 on the ice storage chamber 14 side, and is discharged from the drain provided at the bottom of the ice storage chamber 14. Is discharged. Thus, in the second embodiment, the dew condensation water can be reliably guided to the drainage passage 82 by guiding the dew condensation water to the drainage passage 82 from the notch 92 provided in the front end edge 70b of the slope 68. Further, since a plurality of notches 92 can be set at an arbitrary position on the front end edge 70b of the slope 68, the condensed water can be dispersed and discharged into a plurality of paths by the plurality of notches 92.
