Description

  The present invention relates to a reach-in type showcase in which a front opening of a showcase body is slid open and closed with a pair of left and right sliding doors, and is an improvement on a structure for preventing dripping of condensed water generated in an upper guide frame.

  The upper guide frame that guides the slide door so that it can be opened and closed is disposed on the upper side of the opening of the showcase, and the entire upper guide frame faces the inside and outside of the refrigerator compartment. Therefore, it is inevitable that the frame portion facing the inside of the warehouse is cooled by touching the inside air. Further, when the outside air comes into contact with the cooled frame portion, the water vapor contained in the outside air is condensed, and condensation occurs on the surface of the upper guide frame. When the dew condensation proceeds and a large amount of dew condensation water is generated, it becomes a large water droplet and drops from the guide frame due to its own weight or vibration during opening and closing of the slide door. There was a problem that the dropped water drops flow down the glass surface of the sliding door or fall on the arm or lower frame of the user who takes out the product in the refrigerator compartment.

  In order to prevent these problems, for example, Patent Document 1 discloses a structure that prevents dripping water generated in the guide groove from dropping. In the door structure of the showcase of Patent Document 1, the upper frame member (upper guide frame) of the door is transferred and guided in a state of being inserted into a guide groove provided on the upper frame. At the front edge and the rear edge of the upper frame member of the door, protrusions are formed over the entire length in the width direction of the upper frame member, and a groove is formed on the upper end surface of the upper frame member, which is generated in the guide groove. By receiving the condensed water in this groove, the condensed water is prevented from dripping from the guide groove. Condensed water collected and collected by the groove flows out from both ends of the groove, flows down the side frame members provided on the left and right sides of the door, reaches the lower frame, and is drained.

  In the present invention, a water receiving rib and a water receiving groove for receiving the condensed water are formed in the upper guide frame as a structure for preventing the condensation water from dripping. However, it is disclosed in Patent Document 2 that the groove is formed in the upper guide frame. It is well known. In the door device of the storage of Patent Document 2, a shallow groove is formed in the standing wall portion of the upper rail (upper guide frame) that opens and closes the glass door body, and condensed water generated in the rail groove is stored in this groove. The stored dew condensation water functions as a seal that seals the gap between the standing wall that forms the rail groove and the glass door body.

JP 2009-66296 A (FIG. 2) Japanese Utility Model Publication No. 55-127987 (FIG. 4)

  In the door structure of the showcase of patent document 1, the dew condensation water dripped on the upper end surface of the upper frame member from the upper wall surface of the guide groove can be received by the groove. However, the dew condensation water generated on the front and rear wall surfaces of the guide groove and the dew condensation water generated on the upper wall surface and transmitted to the front and rear wall surfaces cannot be received by the groove and flow down to the opening edge of the guide groove. Condensed water that has flowed down to the opening edge is dropped on the door in a portion where the upper frame member is in the guide groove, and is dropped from the opening edge in a portion where the upper frame member is not in the guide groove. For this reason, it is not possible to reliably eliminate the dew condensation water flowing down the slide door or falling on the arm or lower frame where the product is taken out.

  The groove in the door device of the storage of Patent Document 2 is provided to positively store condensed water and seal the gap between the glass door body and the upper rail using the stored condensed water. It does not contribute to preventing dripping of water. Moreover, since the structure which drains dew condensation water is not provided, when a large amount of dew condensation water arises, there exists a possibility that dew condensation water cannot be stored in a groove | channel. Furthermore, in order for the condensed water stored in the groove to exhibit a sealing function, it is necessary to form a water film in the gap between the glass door body and the upper rail. Therefore, if this water film is broken when the glass door is opened and closed, the condensed water cannot be retained and flows down the glass surface.

  The object of the present invention is to receive the condensed water generated in the guide groove that guides the slide door, drain the received condensed water appropriately, and the condensed water flows down the glass surface of the slide door, or downward from the guide groove. It is to provide a reach-in type showcase that can prevent dripping.

  In the present invention, a pair of left and right sliding doors 4, 4 is disposed in the front opening 3 of the showcase body 1, and both the sliding doors 4, 4 can be freely opened and closed by an opening frame 19 provided in the front opening 3. Targeted reach-in showcases. The opening frame 19 includes an upper guide frame 20 and a lower guide frame 21, and a pair of left and right side frames 22 and 23. The upper guide frame 20 is formed with a front guide groove 35 and a rear guide groove 36 that move and guide the upper portions of the slide doors 4 and 4 open downward, and the front and rear surfaces of the grooves 35 and 36 are the upper guides. The front vertical wall 38, the middle vertical wall 39, and the rear vertical wall 40 provided on the frame 20 are partitioned. A group of water receiving ribs 45 and water receiving grooves 46 are formed in at least two of the vertical walls 38, 39, and 40 alternately along the vertical direction and over the entire length in the horizontal direction. And the dew condensation water received by the water receiving rib 45 and the water receiving groove 46 flows down from the left and right side ends 50 and 51 of the vertical wall through the pair of side frames 22 and 23, and is drained.

  Of the front vertical wall 38, the middle vertical wall 39, and the rear vertical wall 40, at least the left and right side edges 50 and 51 of the vertical wall where the water receiving rib 45 and the water receiving groove 46 are formed flow down the side frames 22 and 23. Adjacent to the wall 29 through a slight gap. The condensed water received by the water receiving rib 45 and the water receiving groove 46 is moved to the flow-down wall 29 by capillary action in the gap.

  Of the front vertical wall 38, the middle vertical wall 39, and the rear vertical wall 40, the water flowed down from the water receiving rib 45 and the water receiving groove 46 to at least the lower part of the vertical wall in which the water receiving rib 45 and the water receiving groove 46 were formed. A housing 52 for receiving the dew condensation water is formed. Condensed water received by the casing 52 flows down from the left and right ends 53 and 54 of the casing 52 through the pair of side frames 22 and 23 and is drained.

  The left and right side ends 53 and 54 of the casing 52 are arranged adjacent to the flow-down wall 29 of the side frames 22 and 23 with a slight gap therebetween. The condensed water received by the casing 52 is moved to the falling wall 29 by capillary action in the gap.

  Water receiving ribs 45 having the same shape and the same size are formed at equal intervals on the front surfaces of the middle vertical wall 39 and the rear vertical wall 40 among the vertical walls, and the same shape and the same size between the adjacent water receiving ribs 45 and 45. The water receiving groove 46 is formed.

  The upper guide frame 20 is composed of an extruded product made of plastic. The upper surface of the water receiving rib 45 is formed by an inclined surface 47 that is inclined upward from the rib base toward the rib tip.

  The upper end of the middle vertical wall 39 and / or the rear vertical wall 40 is continued to the upper wall 37 of the upper guide frame 20 via the forward inclined wall 41. A group of water receiving recesses 49 are formed on the overhang surface 48 of the forward inclined wall 41.

  In the present invention, the upper guide frame 20 of the opening frame 19 is formed with a front guide groove 35 and a rear guide groove 36 for moving and guiding the upper portions of the slide doors 4 and 4 open downward, and the grooves 35. The front and rear surfaces of 36 are partitioned by a front vertical wall 38, a middle vertical wall 39, and a rear vertical wall 40 provided on the upper guide frame 20. Further, a group of water receiving ribs 45 and water receiving grooves 46 are alternately formed in the vertical direction over the entire length in the left-right direction on at least two vertical walls of the vertical walls 38, 39, 40. And the dew condensation water received by the water receiving rib 45 and the water receiving groove 46 flows down from the left and right side ends 50 and 51 of the vertical wall through the pair of side frames 22 and 23 and is drained.

  According to the above dripping prevention structure, the dew condensation water generated on the vertical wall is received by the water receiving rib 45 and the water receiving groove 46, and is further held on the vertical wall by the surface tension of the dew condensation water. Can be prevented from flowing down. Condensed water held on the vertical wall can be moved to the left and right ends 50 and 51 of the vertical wall by capillary action in the water receiving groove 46, and can flow down and drain through the pair of side frames 22 and 23. Therefore, it is ensured that the condensed water adhering to the vertical wall of the upper guide frame 20 flows down the glass surface of the slide door 4 or drops from the lower ends of the front vertical wall 38, the middle vertical wall 39, and the rear vertical wall 40. Can be prevented.

  The left and right side ends 50 and 51 of the vertical wall in which the water receiving rib 45 and the water receiving groove 46 are formed are disposed adjacent to the flow-down wall 29 of the side frames 22 and 23 with a slight gap therebetween, and the water receiving rib 45 and The condensed water received by the water receiving groove 46 was moved to the falling wall 29 by capillary action in the gap. As described above, when the dew condensation water is moved from the left and right side edges 50 and 51 of the vertical wall to the side frames 22 and 23 by using the capillary phenomenon, the dew condensation water held on the vertical wall is smoothly and accurately sided. It can be moved down to the frames 22 and 23 and drained. Moreover, the movement of the dew condensation water moving from the vertical wall to the side frames 22 and 23 can be made gentle by capillary action, and the dew condensation water can flow down in a state of being in close contact with the surface of the side frames 22 and 23 by the surface tension. It is possible to reliably prevent the dew condensation water from dropping from the side frames 22 and 23 in the middle of the flow. Furthermore, it is not necessary to separately provide a structure for moving the dew condensation water that has reached the left and right side edges 50 and 51 of the vertical wall to the falling wall 29. Accordingly, the condensed water can be reliably moved to the flow-down wall 29 with a simple configuration, and the condensed water can be appropriately drained while reducing the manufacturing cost.

  Of the front vertical wall 38, the middle vertical wall 39, and the rear vertical wall 40, the water flowed down from the water receiving rib 45 and the water receiving groove 46 to at least the lower part of the vertical wall in which the water receiving rib 45 and the water receiving groove 46 were formed. According to the upper guide frame 20 in which the housing 52 for receiving the dew condensation water is formed, a large amount of dew condensation water is generated and cannot be completely drained from the left and right side ends 50 and 51 of the vertical wall. Even when the received condensed water flows down, the housing 52 can receive the condensed water and prevent the condensed water from dripping from the lower end of the vertical wall. Further, the dew condensation water received by the housing 52 flows down and drains from the left and right side ends 53 and 54 of the housing 52 through the pair of side frames 22 and 23, so that the dew condensation water may overflow from the housing 52. Absent. Therefore, it is possible to more reliably prevent the condensed water from flowing down the glass surface of the slide door 4 or dripping from the lower end of the vertical wall provided with the casing 52.

  The left and right side ends 53 and 54 of the housing 52 are arranged adjacent to the flow-down walls 29 of the side frames 22 and 23 through a slight gap, and the dew condensation water received by the housing 52 flows into the flow-down wall by capillary action in the gap. It was made to move to 29. As described above, when the dew condensation water is moved from the left and right side ends 53 and 54 of the housing 52 to the side frames 22 and 23 using the capillary phenomenon, the dew condensation water received by the housing 52 is smoothly and accurately obtained. It can be moved to the side frames 22 and 23 to drain and drain. Moreover, the movement of the dew condensation water moving from the housing 52 to the side frames 22 and 23 is made gentle by the capillary phenomenon, and the dew condensation water is allowed to flow down in close contact with the surfaces of the side frames 22 and 23 by the surface tension. It is possible to reliably prevent the condensed water from dripping from the side frames 22 and 23 during the flow. Furthermore, it is not necessary to provide a separate structure for moving the condensed water that has reached the left and right ends 53 and 54 of the housing 52 to the falling wall 29. Accordingly, the condensed water can be reliably moved to the flow-down wall 29 with a simple configuration, and the condensed water can be appropriately drained while reducing the manufacturing cost.

  According to the upper guide frame 20 in which the water receiving rib 45 and the water receiving groove 46 are formed on the front surface of the middle vertical wall 39 and the rear vertical wall 40 among the vertical walls, the shape of the upper guide frame 20 is simplified and the manufacturing cost is reduced. While reducing, it is possible to prevent dew condensation from dripping from the lower ends of the middle vertical wall 39 and the rear vertical wall 40. More specifically, the cool air in the cabinet directly touches the middle vertical wall 39 and the rear vertical wall 40 facing the interior, but does not directly touch the front vertical wall 38 facing the exterior. Therefore, it is sufficient that the water receiving rib 45 and the water receiving groove 46 are formed in front of the middle vertical wall 39 and the rear vertical wall 40 of the vertical walls, and the upper guide frame 20 simplifies the structure. Manufacturing costs can be reduced. Further, when the same shape and the same size of the water receiving ribs 45 are formed at equal intervals, and the same shape and the same size of the water receiving grooves 46 are formed between the adjacent water receiving ribs 45 and 45, both of them are formed by 45 and 46. The surface tension of the condensed water on the uneven surface can be made uniform in the vertical direction so that the condensed water can be received stably. Therefore, it is possible to prevent the received condensed water from flowing inadvertently.

  When the upper surface of the water receiving rib 45 is formed by the inclined surface 47 that is inclined upward from the rib base toward the tip of the rib, the condensed water received by the water receiving rib 45 and the water receiving groove 46 is securely held by the inclined surface 47. Thus, the received condensed water can be prevented from inadvertently flowing down. In addition, according to the upper guide frame 20 made of an extrusion-molded product made of plastic, even if the cross-sectional shape of the upper guide frame 20 is a complicated shape, it can be easily manufactured to suppress an increase in manufacturing cost. Can do.

  The upper end of the middle vertical wall 39 and / or the rear vertical wall 40 is continued to the upper wall 37 of the upper guide frame 20 via the forward inclined wall 41, and a group of water receiving recesses 49 are formed on the overhang surface 48 of the forward inclined wall 41. Formed. As described above, according to the upper guide frame 20 to which the forward inclined wall 41 is added, the condensed water adhering to the upper wall 37 of the front guide groove 35 and the rear guide groove 36 is moved along the overhang surface 48 of the forward inclined wall 41. Thus, it is possible to prevent the condensed water from dripping directly from the upper wall 37 by flowing down to the middle vertical wall 39 and the rear vertical wall 40. In addition, a group of water receiving recesses 49 is provided on the overhanging surface 48, and the condensed water can flow slowly in a state where the condensed water adheres to the group of water receiving recesses 49 by the surface tension. All of the water can be reliably moved to the middle vertical wall 39 and the rear vertical wall 40.

  As shown in FIGS. 1 and 4, the upper guide frame 20 is formed with a front guide groove 35 and a rear guide groove 36 that move and guide the upper collar 12 (upper part) of the sliding doors 4 and 4 open downward. Has been. The upper guide frame 20 includes an upper wall 37, a front vertical wall 38, a middle vertical wall 39, and a rear vertical wall 40 extending below the upper wall 37. The front and rear surfaces of the rear guide groove 36 are partitioned by a middle vertical wall 39 and a rear vertical wall 40. The upper end of the middle vertical wall 39 continues to the upper wall 37 via the forward inclined wall 41. The forward inclined wall 41 is provided to move the dew condensation water generated on the upper wall 37 facing the front guide groove 35 located on the outer side of the warehouse to the middle vertical wall 39 via the forward inclined wall 41. A front fixed wall 42 extends upward at the front end of the upper wall 37, and a rear fixed wall 43 extends rearward at the lower end of the rear vertical wall 40. The upper guide frame 20 is fixed to the front opening 3 by 43. Although not shown, a seal tongue piece is provided at the upper front edge of each slide door 4, and the rear slide door is located between the front surface of the upper end of the front slide door 4 and the rear surface of the front vertical wall 38. The space between the upper front surface of 4 and the rear surface of the middle vertical wall 39 is sealed with a sealing tongue piece to prevent the outflow of the air in the cabinet.

  The upper guide frame 20 and the lower guide frame 21 included in the opening frame 19 and the left and right side frames 22 and 23 are each formed of an extruded product made of plastic. In this embodiment, vinyl chloride is extruded. The strip obtained by molding is cut and processed into a predetermined shape.

  As shown in FIG. 4, the upper guide frame 20 is disposed on the upper side of the front opening 3 of the showcase body 1, and the entire upper guide frame 20 faces the inside and outside of the refrigerator compartment 2. Therefore, it is inevitable that the middle vertical wall 39 and the rear vertical wall 40 facing the inner side of the vertical wall are cooled by touching the air in the warehouse. Further, when the outside air comes into contact with the cooled front surfaces of the middle vertical wall 39 and the rear vertical wall 40, water vapor contained in the outside air is condensed, and dew condensation occurs on the front surfaces of the middle vertical wall 39 and the rear vertical wall 40. Occurs. When the dew condensation proceeds and a large amount of dew condensation water is generated, it becomes a large water droplet and drops from the middle vertical wall 39 and the rear vertical wall 40 due to its own weight or vibration when the slide door 4 is opened and closed. Therefore, a group of water receiving ribs 45 and water receiving grooves are formed in front of the middle vertical wall 39 and the rear vertical wall 40 in order to prevent the condensed water that has become large water droplets from dropping from the lower ends of the vertical walls 39 and 40. 46 is formed.

  As shown in FIG. 1, the group of water receiving ribs 45 and the water receiving grooves 46 are formed alternately along the vertical direction and over the entire length in the horizontal direction. Further, the group of water receiving ribs 45 and the water receiving grooves 46 have the same shape and the same size as the water receiving ribs 45 formed at equal intervals, and have the same shape and the same size between adjacent water receiving ribs 45 and 45. A receiving groove 46 is formed, and is formed in most of the front surfaces of the middle vertical wall 39 and the rear vertical wall 40. The condensed water is received by the surface tension of the condensed water on the uneven surface by the ribs 45 and the grooves 46, and the condensed water is prevented from flowing down the front surfaces of the vertical walls 39 and 40. The cross section of the water receiving rib 45 is formed in a parallelogram shape whose rib tip is higher than the rib base, and the protruding corner portion of the rib tip and the entering corner portion of the rib base are rounded. Thereby, the upper surface of the water receiving rib 45 is formed by the inclined surface 47 that is inclined upward from the rib base toward the rib tip so that the dew condensation water received by the water receiving rib 45 and the water receiving groove 46 can be securely held. It has become.

  Condensed water generated on the upper wall 37 facing the front guide groove 35 flows down along the overhang surface 48 of the forward inclined wall 41 and moves to the middle vertical wall 39. In order to slow down the flow rate of the dew condensation water at this time, a group of water receiving recesses 49 are formed on the overhang surface 48, and the dew condensation water adheres to the water receiving recesses 49 due to its surface tension. And is able to flow down. Since each water receiving recess 49 is formed of a shallow V-shaped groove, the surface tension of the condensed water in the group of water receiving recesses 49 is the surface tension of the condensed water in the water receiving rib 45 and the water receiving groove 46. Smaller than.

  The condensed water received by the water receiving rib 45 and the water receiving groove 46 flows down from the left and right side ends 50 and 51 of the vertical wall through the pair of side frames 22 and 23 and is drained. Specifically, as shown in FIG. 5, the left and right side edges 50 and 51 of the middle vertical wall 39 and the rear vertical wall 40 are arranged adjacent to the flow-down walls 29 and 29 of the side frames 22 and 23 through a slight gap, respectively. Yes. Thereby, the dew condensation water received by the water receiving rib 45 and the water receiving groove 46 can be moved to the falling wall 29 by capillary action in the gap. At this time, the dew condensation water received by the water receiving rib 45 and the water receiving groove 46 moves to the left and right side ends 50 and 51 of the middle vertical wall 39 and the rear vertical wall 40 due to a capillary phenomenon in the water receiving groove 46. The dew condensation water that has moved down flows down the falling wall 29 to the lower guide frame 21 and is drained. Since the movement of the dew condensation water to the flow-down wall 29 due to the capillary phenomenon in the gap is gentle, the dew condensation water can flow down in a state of being in close contact with the surface of the flow-down wall 29 due to the surface tension, and the dew condensation water is in the middle of the flow of the side frame. It can prevent reliably dripping from 22 * 23.

  If a large amount of condensed water is generated, the drainage from the left and right ends 50 and 51 of the vertical wall cannot catch up, and the received condensed water may flow down. In order to prevent the condensed water that has flowed down from dripping from the lower ends of the vertical walls 39 and 40, water receiving ribs 45 and water receivers are provided below the middle vertical wall 39 and the rear vertical wall 40 as shown in FIG. A J-shaped housing 52 is formed to receive the dew condensation water flowing down from the groove 46. The condensed water received by the housing 52 flows down from the left and right side ends 53 and 54 of the housing 52 through the pair of side frames 22 and 23 and is drained. Specifically, the left and right side ends 53 and 54 of the housing 52 are disposed adjacent to the flow-down walls 29 and 29 of the side frames 22 and 23 through a slight gap (see FIG. 5). Thereby, the dew condensation water received by the housing 52 can be moved to the falling wall 29 by capillary action in the gap. The dew condensation water that has moved down flows down the falling wall 29 to the lower guide frame 21 and is drained. Similar to the left and right ends 50 and 51 of the vertical walls 39 and 40, the movement of the dew condensation water to the flow-down wall 29 due to capillary action in the gap is gentle. It is possible to cause the water to flow down in close contact with the water, and to reliably prevent the condensed water from dripping from the side frames 22 and 23 during the flow.

  As shown in FIG. 1, guide protrusions 44 are respectively formed on the lower end of the rear surface of the front vertical wall 38 and the lower end of the rear surface of the middle vertical wall 39, and the front and rear between each guide protrusion 44 and the housing 52. The dimension is set slightly larger than the longitudinal dimension of the slide door 4. The upper collar 12 of the slide door 4 is guided by a guide projection 44 and a casing 52 so as to be slidable. Since the front end surface of the housing 52 protrudes larger forward than the front end surface of the water receiving rib 45, the upper collar 12 of the slide door 4 guided by the guide protrusion 44 and the housing 52 is moved to the water receiving portion. The condensed water received by the rib 45 and the water receiving groove 46 does not move to the slide door 4 and flow down the glass surface.

  As shown in FIG. 6, a water passage hole 55 is formed in the center and rear end seal walls 26 of the lower guide frame 21, and a portion of the guide rail 27 corresponding to the water passage hole 55 is notched. As a result, the dew condensation water that has moved from the left and right ends of the vertical walls 39 and 40 and the left and right ends 53 and 54 of the casing 52 to the flow-down wall 29 and flowed down the flow-down wall 29 to the lower guide frame 21. Is a drainage structure provided in the lower surface of the showcase body 1 (see FIG. 2). The drainage structure is moved into the refrigerator compartment 2 through the water passage hole 55 and the notch portion of the guide rail 27 and provided in the refrigerator compartment 2. ).

  In the above embodiment, only the middle vertical wall 39 is connected to the upper wall 37 via the forward inclined wall 41, but the forward inclined wall in which a group of water receiving recesses 49 are formed on the overhanging surface 48 also in the rear vertical wall 40. It can be continued to the upper wall 37 through 41.

  FIG. 7 shows another embodiment of the upper guide frame 20. There, a group of water receiving ribs 45 and water receiving grooves 46 are formed on the rear surface of the front vertical wall 38, the front and rear surfaces of the middle vertical wall 39, and the front surface of the rear vertical wall 40, and the water receiving ribs 45 and the water receiving grooves 46 are formed. The casings 52 were respectively formed in the lower part of the vertical wall where the Further, the front inclined wall 41 of the previous embodiment is omitted, and an inverted V-shaped ceiling wall 58 is provided below the upper wall 37 facing the front guide groove 35 and the rear guide groove 36, and the front and rear sides of the ceiling wall 58 are further provided. A group of water receiving recesses 49 was formed on the overhanging surface 48 of the above. The sliding door 4 is guided to move by a pair of front and rear housings 52 and 52. According to this configuration, the dew condensation water generated on the ceiling wall 58 can be received by the water receiving rib 45 and the water receiving groove 46 after gently flowing down the overhanging surface 48, so the front guide groove 35 and the rear guide All of the condensed water generated on the inner wall surface defining the groove 36 can be received by the water receiving rib 45 and the water receiving groove 46. Further, the dew condensation water that has overflowed from the water receiving rib 45 and the water receiving groove 46 can be received by each housing 52. Therefore, all the condensed water generated in the front guide groove 35 and the rear guide groove 36 can be reliably received and drained.

  As described above, according to the showcase of the present invention, a group of water receiving ribs 45 and water receiving grooves 46 are formed on the vertical wall alternately along the vertical direction and over the entire length in the horizontal direction. Condensed water received by the receiving rib 45 and the water receiving groove 46 flows down from the left and right side edges 50 and 51 of the vertical wall through the pair of side frames 22 and 23, and is drained. Condensed water is received by the water receiving rib 45 and the water receiving groove 46, and is further held on the vertical wall by the surface tension of the condensed water, so that the condensed water can be prevented from flowing down along the vertical wall. Condensed water held on the vertical wall can be moved to the left and right ends 50 and 51 of the vertical wall by capillary action in the water receiving groove 46, and can flow down and drain through the pair of side frames 22 and 23. Therefore, it is ensured that the condensed water adhering to the vertical wall of the upper guide frame 20 flows down the glass surface of the slide door 4 or drops from the lower ends of the front vertical wall 38, the middle vertical wall 39, and the rear vertical wall 40. Can be prevented.

  The left and right side edges 50 and 51 of the vertical wall are disposed adjacent to the flow-down walls 29 of the side frames 22 and 23 through a slight gap, and the dew condensation water received by the water receiving rib 45 and the water receiving groove 46 is removed from the gap. Therefore, the condensed water held on the vertical wall can be smoothly and accurately moved to the side frames 22 and 23 to flow down and be drained. Further, it is not necessary to separately provide a structure for moving the condensed water that has reached the left and right side ends 53 and 54 of the housing 52 to the flow-down wall 29. Accordingly, the condensed water can be reliably moved to the flow-down wall 29 with a simple configuration, and the condensed water can be appropriately drained while reducing the manufacturing cost.

  According to the upper guide frame 20 in which the casing 52 is formed in the lower part of the vertical wall where the water receiving rib 45 and the water receiving groove 46 are formed, the dew condensation water received by the water receiving rib 45 and the water receiving groove 46 overflows. Even when the water flows down along the vertical wall, the housing 52 can receive the condensed water and prevent the condensed water from dripping from the lower end of the vertical wall. Further, the dew condensation water received by the housing 52 flows down and drains from the left and right side ends 53 and 54 of the housing 52 through the pair of side frames 22 and 23, so that the dew condensation water may overflow from the housing 52. Absent. Therefore, it is possible to reliably prevent the condensed water from flowing down the glass surface of the slide door 4 or dripping from the lower end of the vertical wall provided with the casing 52.

  The left and right side ends 53 and 54 of the housing 52 are arranged adjacent to the flow-down walls 29 of the side frames 22 and 23 through a slight gap, and the dew condensation water received by the housing 52 flows into the flow-down wall by capillary action in the gap. Therefore, the dew condensation water received by the housing 52 can be smoothly and accurately moved to the side frames 22 and 23 to flow down and be drained. Further, it is not necessary to separately provide a structure for moving the condensed water that has reached the left and right side ends 53 and 54 of the housing 52 to the flow-down wall 29. Accordingly, the condensed water can be reliably moved to the flow-down wall 29 with a simple configuration, and the condensed water can be appropriately drained while reducing the manufacturing cost.

  The cool air inside the cabinet directly touches the middle vertical wall 39 and the rear vertical wall 40 facing the interior, but does not directly touch the front vertical wall 38 facing the outside. Therefore, the water receiving rib 45 and the water receiving groove 46 may be formed on the front surfaces of the middle vertical wall 39 and the rear vertical wall 40 of the vertical walls. Thus, according to the upper guide frame 20 in which the water receiving ribs 45 and the water receiving grooves 46 are formed on the front surfaces of the middle vertical wall 39 and the rear vertical wall 40 among the vertical walls, the shape of the upper guide frame 20 is simplified. Thus, it is possible to prevent the condensed water from dripping from the lower ends of the middle vertical wall 39 and the rear vertical wall 40 while reducing the manufacturing cost. In addition, the same shape and the same size of the water receiving ribs 45 are formed at equal intervals, and the water receiving groove 46 of the same shape and the same size is formed between the adjacent water receiving ribs 45 and 45. The surface tension of the condensed water on the uneven surface to be formed can be made uniform in the vertical direction to stably receive the condensed water. Therefore, it is possible to prevent the received condensed water from flowing inadvertently.

  Since the upper surface of the water receiving rib 45 is formed by the inclined surface 47 that is inclined upward from the rib base toward the rib tip, the condensed water received by the water receiving rib 45 and the water receiving groove 46 is securely held by the inclined surface 47. Thus, the received condensed water can be prevented from inadvertently flowing down. In addition, according to the upper guide frame 20 made of an extrusion-molded product made of plastic, even if the cross-sectional shape of the upper guide frame 20 is a complicated shape, it can be easily manufactured to suppress an increase in manufacturing cost. Can do.

  Since the upper end of the middle vertical wall 39 is connected to the upper wall 37 of the upper guide frame 20 via the forward inclined wall 41 and a group of water receiving recesses 49 are formed in the overhanging surface 48 of the forward inclined wall 41, the front guide groove The condensed water adhering to the upper wall 37 of the 35 can be caused to flow down to the middle vertical wall 39 along the overhang surface 48 of the forward inclined wall 41, and the condensed water can be prevented from dropping directly from the upper wall 37. In addition, since the group of water receiving recesses 49 is provided on the overhanging surface 48, the condensed water can flow down slowly with the surface tension being attached to the group of water receiving recessed portions 49, so that the overhanging surface 48 flows down. All the condensed water can be reliably moved to the middle vertical wall 39 and the rear vertical wall 40.

  In the above embodiment, the water receiving ribs 45 having the same shape and the same size are formed at equal intervals to form the water receiving grooves 46 having the same shape and the same size. The water receiving groove 46 between the adjacent water receiving ribs 45 and 45 need not be the same shape and the same size. In short, it is sufficient that the condensed water can be received by the surface tension of the condensed water on the uneven surface formed by the water receiving rib 45 and the water receiving groove 46.
