Moreover, the shape of the receiving member 21 in the refrigerated showcase 1 to be described later can be made common.

  As shown in FIG. 3B and FIG. 6, the cross-sectional view shape of the receiving member 21 will be described in detail. The bulging portions 21b and 21e bulging inward are provided, and the space between the facing surfaces of the bulging portions 21b and 21e is formed slightly larger than the thickness of the windshield 22. Therefore, by fitting the windshield glass 22 to the receiving member 21 along the bulging portions 21b and 21e, the windshield glass 22 inside the receiving member 21 is positioned, and above and below the bulging portions 21b and 21e, A predetermined gap described later is formed between the outer surface of the windshield 22 and the inner wall surface of the receiving member 21.

  That is, above the bulging portion 21b on the right side of the figure, a gap formed in the front-rear direction between the outer surface 22a of the windshield 22 and the inner wall surface of the receiving member 21 constituting the outer surface of the refrigerated showcase 1 is As will be described later, the water receiving portion 21 a is configured to receive the dew condensation water generated on the outer surface of the windshield 22. Similarly, a water receiving portion 21 d is formed between the outer surface 22 b of the windshield glass 22 constituting the inner side surface of the refrigerated showcase 1 and the inner wall surface of the receiving member 21. Although not particularly illustrated, the left side surface of the refrigerated showcase 1 has the same configuration as described above.

  In addition, a gap having a predetermined width is formed in the front-rear direction between the outer surface 22a of the windshield 22 and the inner wall surface of the receiving member 21 that form the outer surface of the refrigerated showcase 1 below the bulging portion 21b. In addition, this gap opens forward. This gap is configured as a water conduit 21c that drains the condensed water as will be described later. Similarly, a water conduit 21 f is formed between the outer surface 22 b of the windshield 22 that forms the inner surface of the refrigerated showcase 1 and the inner wall surface of the receiving member 21.

  Further, as shown in FIGS. 3B and 4, a fitting 24 that prevents the fitted windshield 22 and the cover 23 from being detached from the receiving member 21 is provided on the front side of the receiving member 21. The member 21 and the side plate main body 20 are fixedly attached as will be described later. The fixture 24 will be described in detail. The fixture 24 includes a covering portion 24a that covers the front end of the receiving member 21 and the side plate main body 20 in front of the front end, and an extension that extends from the covering portion 24a toward the refrigerator compartment 5 side. 24b and the insertion piece 24c which has the width | variety substantially the same as the water conduit 21c, and extends from the coating | coated part 24a whose height dimension is smaller than the water conduit 21c. The back surface side of the covering portion 24a and the extension portion 24b is composed of an outer wall 25a and an inner wall 25b that continues to the outer wall 25a at the top side, and expands downward in the mounted state and has a substantially V-shaped sectional view. A drainage channel 25 having a shape is formed substantially continuously with the insertion piece 24c up to a drainage port 26 opened in the extension 24b. That is, the above-described water conduit 21 c communicates with the drain channel 25 and the drain port 26.

  As shown in FIG. 5, the attachment of the attachment 24 will be described. The insertion piece 24 c of the attachment 24 is inserted in the front-rear direction along the water conduit 21 c of the receiving member 21, and a fixing screw serving as a fixing means. 27 is inserted into an insertion hole 24d (see FIG. 4) provided in the extension 24b and screwed into the inner surface of the side plate main body 20, so that the fixture 24 is fixed to the receiving member 21 and the side plate main body 20. Install to. In the state where the fixture 24 is attached, the drain port 26 opens toward the suction port 11 of the air curtain 12. By doing in this way, the fixture 24 which fixes the windshield glass 22 which comprises the side plate of the refrigerated showcase 1 with respect to the side plate main body 20 from the coating | coated part 24a inserted by the clearance gap between the receiving member 21 and a windshield outer surface. Since it is fixed at two points by the extended insertion piece 24c and a fixing screw 27 that is fixed to the inner surface of the side plate main body 20, the attachment member 24 is prevented from being detached or damaged, and the receiving member 21 and the windshield glass 22 are The end can be secured.

  Further, as described above, by inserting the insertion piece 24c formed in substantially the same width as the water conduit 21c in the front-rear direction, the left and right side surfaces of the insertion piece 24c are in contact with the inner wall surface of the receiving member 21 and the outer surface 22a of the windshield 22 The fixture 24 can be restrained and positioned in the left-right direction, and the fixture 24 can be restrained and positioned in the front-rear direction by screwing a fixing screw 27 as a fixing means in the left-right direction.

  As shown in FIG. 6, a gap 21g having a predetermined height communicating with the water conduit 21c is formed below the insertion piece 24c fitted into the water conduit 21c.

  Next, drainage of condensed water generated on the outer surface of the windshield 22 will be described.

  By refrigerating the inside of the refrigerator compartment 5 of the refrigerated showcase 1 to a predetermined temperature, the air in the refrigerator compartment 5 naturally becomes lower in temperature than the air outside the refrigerated showcase 1. The air in the vicinity of the outer surface 22a of the windshield 22 constituting the outer surface of the refrigerated showcase 1 is cooled by the low-temperature air in the refrigerated chamber 5, so that the saturated water vapor amount decreases and the humidity increases and reaches the dew point. The water vapor in the air in the vicinity of the outer surface 22 a of the windshield 22 becomes water droplets and is generated as condensed water D on the outer surface 22 a of the windshield 22.

  Thus, the dew condensation water D generated on the outer surface 22a of the windshield 22 is received by the gravity and is formed between the outer surface 22a of the windshield 22 and the inner wall surface of the receiving member 21 along the outer surface 22a. It moves to the water conduit 21c through the part 21a. Next, in the refrigerating room 5, as described above, due to the flow of the air curtain 12 blown from the cold air outlet 10 provided at the upper front end toward the inlet 11 provided at the lower front end (see FIG. 1), the inlet A negative pressure is generated in the water conduit 21c that communicates with the drain 26 that opens toward 11, and the condensed water D in the water conduit 21c flows through the drain 25 (see the white arrow in FIG. 7). Suction toward the mouth 26 side.

  Thus, since the receiving member 21 interposed between the opening 20a of the side plate body 20 and the windshield 22 is easily molded with substantially the same cross-sectional shape in the front-rear direction, additional processing after molding is performed. Without need, the dew condensation water D generated on the outer surface 22a of the windshield 22 can be drained. Moreover, since it drains using the fixture 24 for fixing the windshield 22, it can drain easily to the refrigerator compartment 5 side, without requiring an additional component.

  In addition, as described above, the drain port 26 opens toward the suction port 11, and in this way, the condensed water D in the water conduit 21 c is moved from the cold air outlet 10 toward the suction port 11. Using the cold air blown out from the air curtain 12 (see FIG. 1), the air curtain 12 can flow toward the drain outlet 26 communicating with the water conduit 21c without requiring a separate drainage means, and drain to the refrigerator compartment 5 side. Therefore, by preventing the dew condensation water D from staying, generation of soot and the like can be prevented, and the cleanliness inside the receiving member 21 can be maintained. Further, since the drained dew condensation water D is drawn into the ventilation path 7 in the suction port 11 together with the cold air, the bottom plate 3b (see FIG. 1) of the refrigerator compartment 5 and the displayed merchandise are clean and clean.

  As shown in FIGS. 6 and 7, due to this suction, the dew condensation water D moves in the water guide passage 21c and passes through the gap 21g below the insertion piece 24c inserted into the front end side of the water guide passage 21c. To the drainage channel 25. As described above, by inserting the insertion piece 24c of the fixture 24 formed in substantially the same width into the water conduit 21c of the receiving member 21, the positional displacement between the water conduit 21c and the drainage passage 25 is eliminated. Condensed water D generated on the outer surface 22a of the windshield 22 can be reliably drained to the refrigerator compartment 5 side through the drain outlet 26, and drainage can be newly performed by using the fixture 24 for fixing the windshield 22. There is no need to prepare parts for.

  In this embodiment, the drainage channel 25 includes an outer wall 25a and an inner wall 25b. The outer wall 25a extends downward so as to contact the peripheral surface of the side plate body 20 over the longitudinal direction of the drainage channel 25. On the other hand, the inner wall 25 b extends slightly shorter than the outer wall 25 a so as to be separated from the peripheral surface of the side plate body 20 along the longitudinal direction of the drainage channel 25. A waterproof sealing material may be provided along the longitudinal direction at the lower end of the outer wall 25a.

  Due to the above-described configuration of the drainage channel 25, the dew condensation water D that has flowed from the water conduit 21 c to the drainage channel 25 side is not only the end of the drainage channel 25 on the water conduit 21 c side, but also the side plate in the covering portion 24 a of the fixture 24. It flows into the drainage channel 25 from anywhere in the longitudinal direction of the drainage channel 25 along the side peripheral surface of the main body 20, and is sucked toward the drainage port 26 mainly along the outer wall 25a. In addition, the appearance is improved because the drainage is not easily visible.

  Further, due to the above-described configuration of the drainage channel 25, not only the gap between the outer surface 22 a of the windshield glass 22 constituting the outer side surface of the refrigerated showcase 1 and the inner wall surface of the receiving member 21 but also the inner side surface of the refrigerated showcase 1. The water conduit 21 f which is a gap between the outer surface 22 b of the windshield 22 and the inner wall surface of the receiving member 21 is also communicated with the drainage channel 25 and the drainage port 26. In this way, for example, as shown in FIG. 6, the adhering water S attached to the outer surface 22 b of the windshield 22 constituting the inner surface of the refrigerated showcase 1 when the inside of the refrigerated chamber 5 is washed with water, as shown in FIG. 6. Similarly to the condensed water D described above, the negative pressure generated by the flow of the air curtain 12 can be sucked toward the drain outlet 26 side.

  Furthermore, since the drainage channel 25 is formed in a substantially V-shaped cross-sectional view that expands downward and the cross section is open, in the vicinity of the apex angle between the outer wall 25a and the inner wall 25b having a relatively small cross-sectional area, By the capillary phenomenon using the surface tension of the dew condensation water D, drainage can be efficiently performed toward the drain outlet 26 in the longitudinal direction of the drainage channel 25.

  And the dew condensation water D discharged | emitted from the drain outlet 26 flows in the ventilation path 7 via the suction inlet 11 provided under the drain outlet 26, and is drained from the drain hole 14 to the drain pipe 15 side. become. By doing in this way, the dew condensation water D which generate | occur | produced on the outer surface 22a of the windshield 22 or the adhering water S adhering to the outer surface 22b is provided in the ventilation path 7 without providing a special drainage facility. By using the drain hole 14, the water can be drained together with moisture generated when the air curtain 12 is generated.

  Further, the drainage channel 25 extends from the rear surface side of the side plate body 20 to the front side from the outer surface 22a side of the windshield 22 constituting the outer side surface of the refrigerated showcase 1 to the drain port 26 provided on the inner side surface of the refrigerated showcase 1. It is formed in an oblique direction so as to go to. By doing in this way, when the side peripheral surface of the side plate main body 20 is an inclined surface inclined downward from the rear side toward the front side, the inclined surface is used to form the oblique direction described above. The dew condensation water D can be smoothly passed through the drainage channel 25 formed.

  In the present embodiment, the drainage channel 25 communicating with the water conduit 21c and the drainage port 26 has a shape with an open cross section, but is not necessarily limited to the above configuration. For example, as a modification, the cross section is closed. You may be comprised by the tubular shape continuous in a longitudinal direction. It is desirable that the drainage channel configured in a tubular shape communicates from the high place to the low place from the covering portion 24a continuous to the water conduit to the extension portion 24b continuous to the drain port. By doing in this way, drainage can be performed smoothly using gravity going downward.

  Furthermore, the drainage channel configured in the tubular shape as in the above-described modification is formed so that the cross-sectional area of the substantially orthogonal cross section with respect to the drainage direction is smaller than the cross-sectional area of the approximately orthogonal cross section with respect to the water guiding direction in the water conduit. Is desirable. By doing in this way, the dew condensation can be smoothly conducted by guiding the dew condensation water from the water guide channel to the drain channel by the capillary phenomenon using the surface tension of the dew condensation water.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above-described embodiment, as an open showcase, the refrigerator compartment 5 is provided in the main body which is composed of the outer box 2 and the inner box 3 and in which a cold air passage is formed between the outer box 2 and the inner box 3. However, the open showcase is not necessarily limited to the above configuration, and includes an ordinary open showcase having no refrigeration function. Further, in the normal open showcase, there is no temperature difference between the inside and outside of the open showcase, and no condensed water is generated, so that a special water conduit is formed in the receiving member as in the above embodiment.
