The ice making unit 60 includes a rectangular box-shaped ice making substrate 63 and an inner surface 63A of the ice making substrate 63. The ice making chamber 61 is formed by the partition member 64 provided in the structure, and the evaporation pipe 62 is provided on the outer surface 63B of the ice making substrate 63. A side wall 65 extending downward is formed at the peripheral edge of the ice making substrate 63. The partition member 64 extends in the vertical direction, which is the short direction of the ice making chamber 61, and a plurality of (five in FIG. 7) first partition plates 66 that extend in the lateral direction that is the longitudinal direction of the ice making chamber 61. A plurality (five in FIG. 7) of second partition plates 67 are assembled in a lattice shape, and a plurality of rectangular parallelepiped ice making chambers are defined by the partition plates 66 and 67. Each first partition plate 66 is formed with a plurality of upward slits 68 that open upward at predetermined intervals. Each second partition plate 67 has a downward slit 69 that opens downward. A plurality are formed corresponding to 68. Therefore, each first partition plate 66 and each second partition plate 67 are engaged with each other by the upward slit 68 and the downward slit 69, so that the upper edge of each first partition plate 66 and each second partition plate 67 are engaged. Are connected in a state in which their upper end edges are aligned.

  In the conventional ice making unit 60, the partition member 64 is fixed to the ice making substrate 63 in the following manner: (1) Each first partition plate 66 and each second partition plate 67 of the partition member 64 is post-processed into the ice making substrate 63. (2) a configuration in which the partition member 64 is bonded to the ice making substrate 63 by a bonding material such as wax. FIG. 7 and FIG. 8 show an example in which the fixing form (1) is adopted, and a plurality of fixing protrusions 70 projecting upward are formed on the upper edge of each first partition plate 66 and each second partition plate 67. Is formed. As shown in FIG. 8A, each fixing protrusion 70 is formed in a cross-sectional shape in which one side has a substantially square shape with the same dimension as the thickness of the partition plates 66 and 67. The protruding height from the upper edge is set to be larger than the thickness of the ice making substrate 63 as shown in FIG. The ice making substrate 63 has a plurality of fixing holes 71 corresponding to the fixing protrusions 70. As shown in FIG. 8A, the fixing hole 71 has a circular shape with a size that allows the fixing protrusion 70 to be inserted. Each fixing protrusion 70 is inserted into the corresponding fixing hole 71, and the tip of the fixing protrusion 70 protruding to the outer surface 63B side of the ice making substrate 63 is crushed by a hammer or the like (FIG. 8A). 8B), the fixing protrusion 70 whose tip is deformed engages with the edge of the fixing hole 71, and the partition member 64 (first partition plate 66, second partition plate 67). Is fixed to the ice making substrate 63. In addition, after attaching the partition member 64 to the ice-making board | substrate 63, the ice making part 60 is plated with the whole surface by tin.

  Further, although the illustration of the fixing form of (2) is omitted, a bonding material (paste wax) is provided on the inner surface 63A of the ice making substrate 63 in the ice making chamber 61 at the portion where the first partition plate 66 and the second partition plate 67 abut.

JP 2006-118816 A

  By the way, in the fixed form of (1), as shown in FIGS. 8 (a) and 8 (b), when the tip of the fixing protrusion 70 is crushed and squeezed with a hammer or the like, the tip is fixed. Although the diameter of the hole 71 is appropriately larger than the diameter of the hole 71, the portion of the fixing protrusion 70 inserted into the fixing hole 71 is hardly deformed, and therefore, the gap between the outer surface of the fixing protrusion 70 and the inner surface of the fixing hole 71 is changed. A gap 72 is generated. If a gap 72 is formed in each fixed hole 71, water flows in, and the water flowing into the gap 72 freezes and expands during the ice making-deicing cycle operation, so that the ice making chamber 61 is deformed. There is a problem that the ice making substrate 63 and the first partition plate 66 or the second partition plate 67 are separated to form a gap, or the ice making chamber 61 is damaged in some cases. Further, in the method of fixing the fixed projection 70 by caulking, as shown in FIG. 8B, the fixed projection 70 protrudes from the outer surface of the ice making substrate 63, so that the outer surface of the ice making substrate 63 is fixed. When the evaporation tube 62 comes into contact with the fixing projection 70 when the evaporation tube 62 is disposed on 63B, a gap is formed between the ice making substrate 63 and the evaporation tube 62, and the evaporation tube 62 is fixed to the ice making substrate 63. Problems such as a decrease in strength and a decrease in cooling efficiency of the ice making chamber 61 occur. In addition, various costs associated with the caulking process for the fixed protrusions 70 are required, and the number of the fixed protrusions 70 is large, resulting in increased manufacturing costs.

  On the other hand, in the fixed form of (2), it is difficult to apply the bonding material with a constant width and thickness, and when the application width of the bonding material increases, the bonding material becomes the first partition plate 66 and the second partition plate 66. There is a problem that it protrudes from the partition plate 67 and causes a deterioration in quality. Moreover, it is necessary to prepare a dedicated jig for applying the bonding material, and there is a problem that the equipment cost increases.

  Accordingly, the present invention has been proposed to solve the above-described problems inherent in the conventional technology, and is an automatic ice making machine in which a partition member is appropriately fixed to an ice making substrate. The purpose is to provide an ice making part.

Since it extends obliquely so as to be separated from the first fixed protrusion 35 and inclines downward toward the gap R, the liquid bonding material V supplied onto the inner surface chamfer 27 is directed toward the gap R. It is designed to guide you down. On the other hand, the outer chamfered portion 39 located at the tapered protrusion 35B of the first fixed protrusion 35 extends obliquely away from the first fixed hole 25 toward the protruding end, as shown in FIG. Since it is inclined downward toward the gap R, the liquid bonding material V supplied onto the outer chamfered portion 39 is guided to flow down toward the gap R.

  And in the outer periphery of the taper protrusion 35B of the 1st fixing protrusion 35, as shown in FIG.4 (b) and FIG.5 (c)-FIG.5 (e), the expansion hole part of the 1st fixing hole 25 is shown. A groove 50 opened in the outer surface 13B of the top plate 20 is extended by 25B and 26B. As a result, as shown in FIGS. 6B and 6C, even when the liquid bonding material V to be inserted into the gap R remains, the surplus portion of the liquid bonding material V can be accumulated in the groove 50. Is possible.

  Further, in the ice making chamber 11 of the ice making unit 10 of the embodiment, as shown in FIG. 2, each outer horizontal partition plate 30A in the horizontal partition plate 30 is defined by each outer horizontal partition plate 30A. For each ice making chamber 15 adjacent to the partition plate 30A, a first fixing projection 35 is provided correspondingly. That is, each outer lateral partition plate 30 </ b> A is adjacent to six ice making chambers 15 defined in series in the horizontal direction, and thus has a first fixing protrusion 35 for each of the six ice making chambers 15. . Further, the first fixing projection 35 corresponds to each inner side partition plate 30B in the side partition plate 30 for each ice making chamber 15 defined by each inner side partition plate 30B and adjacent to the inner side partition plate 30B. Is provided. Each inner horizontal partition plate 30B includes six ice making chambers 15 defined in series in the lateral direction on the front side of the inner horizontal partition plate 30B and six ice making chambers defined in series in the lateral direction on the rear side. Each of the ice making chambers 15 and 15 adjacent to each other in the longitudinal direction is provided with a first fixing projection 35 correspondingly to each of the ice compartments 15 and 15 adjacent to each other. In addition, the first fixing projections 35 provided on the outer side partitioning plate 30 </ b> A and the inner side partitioning plate 30 </ b> B in the horizontal partitioning plate 30 are adjacent in the lateral direction defining the ice making chamber 15 adjacent to the first fixing projection 35. It is provided so that it may be located in the center between the vertical partition plates 40 and 40 which fit.

  Further, as shown in FIG. 2, a second fixing projection 45 corresponds to each vertical partition plate 40 for each ice making chamber 15 defined by each vertical partition plate 40 and adjacent to the vertical partition plate 40.

As described above, the outer surface 13B of the top plate portion 20 of the ice making substrate 13 is flat because the first fixing protrusion 35 and the second fixing protrusion 45 of the partition member 14 do not protrude, and the evaporation pipe 12 A portion located on the outer surface 13B of the top plate portion 20 is in contact with the outer surface 13B. Therefore, when the refrigerant cooled in the refrigeration circuit passes through the evaporation pipe 12, efficient heat exchange between the refrigerant and the ice making chamber 11 is performed, and the ice making substrate 13 and the partition member 14 of the ice making chamber 11 are exchanged. By efficiently cooling, the ice making efficiency of each ice making chamber 15 is enhanced.

(Operation of Example)
Next, the operation of the ice making unit 10 of the automatic ice making machine according to the embodiment will be described.

  When manufacturing the ice making unit 10, first, as shown in FIG. 3, the two outer lateral partition plates 30 </ b> A and 30 </ b> A are set on the ice making substrate 13. That is, the first fixing protrusions 35 of the outer lateral partition plates 30A and 30A are inserted from below into the corresponding first fixing holes 25 provided in the top plate portion 20 of the ice making substrate 13, and the outer lateral partition plates are inserted. The left hanging hook portion 33 provided on the main body portion 32 of 30A is fitted into the left hanging recessed portion 28 provided on the left side plate portion 21 of the ice making substrate 13 from below, and the right hanging hook portion 34 is attached to the ice making substrate 13. It fits from below into a right latching recess 29 provided in the right side plate 22. As a result, the two outer lateral partition plates 30 </ b> A and 30 </ b> A are temporarily set on the ice making substrate 13.

  Next, the five vertical partition plates 40 are set on the ice making substrate 13. That is, each second fixing protrusion 45 provided on each vertical partition plate 40 is inserted from below into the corresponding second fixing hole 26 provided on the top plate portion 20 of the ice making substrate 13, and the main body of each vertical partition plate 40. The front latching bar 43 provided in the part 42 is fitted from below to the front latching recess 36 provided in the outer lateral partition plate 30A on the front side, and the rear latching bar provided in the main body 42 44 is fitted from below to the rear latching recess 37 provided on the rear lateral partition plate 30A. Accordingly, the five vertical partition plates 40 are temporarily set on the ice making substrate 13.

  Next, the two inner lateral partition plates 30 </ b> B and 30 </ b> B are set on the ice making substrate 13. That is, the first slits provided on the main body 32 of each inner transverse partition plate 30B after the upward slits 38 of each inner transverse partition plate 30B and the downward slits 46 of each vertical partition plate 40 are engaged with each other. 35 is inserted into the corresponding first fixing holes 25 provided in the top plate portion 20 of the ice making substrate 13 from below, and the left latching rod portion 33 provided in the main body portion 32 of each inner lateral partition plate 30B is The left latching recess 28 provided in the left side plate portion 21 of the ice making substrate 13 is fitted from below, and the right latching portion 34 is opposed to the right latching recess 29 provided in the right side plate portion 22 of the ice making substrate 13. Fit from below. Accordingly, the two inner horizontal partition plates 30 </ b> B and 30 </ b> B are temporarily set on the ice making substrate 13.

  When the temporary setting of the horizontal partition plate 30 and the vertical partition plate 40 of the partition member 14 with respect to the ice making substrate 13 is completed, the evaporation tube 12 formed in a serpentine shape on the outer surface 13B of the top plate portion 20 of the ice making substrate 13 is liquidized. Fix with the bonding material V. Further, by supplying the liquid bonding material V to the grooves 50 formed in the respective first fixing holes 25 into which the first fixing protrusions 35 are inserted, the liquid bonding material V is allowed to be chamfered on the outer side of the first fixing protrusions 35. After flowing down along the portion 39 and the inner surface chamfer 27 of the first fixing hole 25, it flows into the gap R between the first fixing protrusion 35 and the first fixing hole 25. Then, the liquid bonding material V that has flowed into the gap R reaches the gap R due to the capillary phenomenon, and is solidified within the gap R. When the liquid bonding material V is solidified in the gap R, the lateral partition plates 30 (the outer lateral partition plate 30A and the inner lateral partition plate 30B) are fixed to the ice making substrate 13. As shown in FIGS. 5C and 5D, the upper end surface of the main body portion 32 of the horizontal partition plate 30 and the lower surface of the top plate portion 20 of the ice making substrate 13 are in close contact with each other so that almost no gap is formed. Therefore, the liquid bonding material V that has flowed into the gap R and has spread does not easily flow between the upper end surface of the main body portion 32 and the lower surface of the top plate portion 20 (FIGS. 6B and 6C). . Further, the liquid bonding material V retained in the groove 50 is solidified in the groove 50 (FIGS. 6B and 6C).

  Further, by supplying the liquid bonding material V to the grooves 50 formed in the respective second fixing holes 26 into which the second fixing protrusions 45 are inserted, the liquid bonding material V is outside the second fixing protrusions 45. After flowing down along the chamfered portion 39 and the inner side chamfered portion 27 of the second fixing hole 26, it flows into the gap R between the second fixing protrusion 45 and the second fixing hole 26. Then, the liquid bonding material V that has flowed into the gap R reaches the gap R due to the capillary phenomenon, and is solidified within the gap R. When the liquid bonding material V is solidified in the gap R, the vertical partition plate 40 is fixed to the ice making substrate 13. As shown in FIGS. 5C and 5D, the upper end surface of the main body portion 32 of the horizontal partition plate 30 and the lower surface of the top plate portion 20 of the ice making substrate 13 are in close contact with each other so that almost no gap is formed. Therefore, the liquid bonding material V that has flowed into the gap R and has spread does not easily flow between the upper end surface of the main body portion 32 and the lower surface of the top plate portion 20 (FIGS. 6B and 6C). . Further, the liquid bonding material V retained in the groove 50 is solidified in the groove 50 (FIGS. 6B and 6C).

  The ice making unit 10 is configured by fixing the evaporation tube 12 to the ice making substrate 13, and the ice making unit 10 is completed by performing a plating process with tin on the ice making unit 10.

  Therefore, according to the ice making unit 10 of the automatic ice maker according to the embodiment, the space is defined between the outer surface of the first fixing protrusion 35 inserted into the first fixing hole 25 and the inner surface of the first fixing hole 25. When the liquid bonding material V enters the gap R, the liquid bonding material V spreads and spreads into the gap R due to capillary action, and then solidifies, and the horizontal partition plate 30 (the outer horizontal partition plate 30A and the inner horizontal partition). The plate 30B) can be appropriately and reliably fixed to the ice making substrate 13. Similarly, when the liquid bonding material V enters the gap R defined between the outer surface of the second fixing protrusion 45 inserted into the second fixing hole 26 and the inner surface of the second fixing hole 26, The bonding material V spreads and spreads into the gap R due to capillary action, and then solidifies, so that the vertical partition plate 40 can be appropriately and reliably fixed to the ice making substrate 13. Therefore, the partition member 14 composed of the horizontal partition plate 30 and the vertical partition plate 40 can be fixed by a small amount of the liquid bonding material V. Further, since the gap R between the first fixing hole 25 and the first fixing protrusion 35 and the gap R between the second fixing hole 26 and the second fixing protrusion 45 are solidified in a state where the liquid bonding material V is filled. In addition, water does not flow into each gap R, and deformation, separation, breakage, and the like of the ice making substrate 13 and the partition member 14 due to freezing of the water flowing into the gap R can be prevented.

  The protruding height H1 of each first fixed protrusion 35 from the upper end of the main body portion 32 and the protruding height H2 of each second fixed protrusion 45 from the upper end of the main body portion 42 are the thickness T3 of the top plate portion 20 of the ice making substrate 13. Therefore, the first fixing protrusion 35 inserted into the first fixing hole 25 and the second fixing protrusion 45 inserted into the second fixing hole 26 do not protrude from the outer surface 13B of the ice making substrate 13. Thereby, the outer surface 13B of the top plate portion 20 of the ice making substrate 13 becomes flat and can be fixed in a state where the evaporation tube 12 is in close contact with the outer surface 13B of the top plate portion 20, and the evaporation with respect to the ice making substrate 13 is performed. The tube 12 can be fixed easily and appropriately. Furthermore, since no post-processing is required to caulk the fixing protrusions, etc., a caulking machine is not required, equipment costs are reduced, work time is shortened, and work man-hours are reduced, thus reducing manufacturing costs. it can.

  In addition, since the first fixed protrusion 35 and the second fixed protrusion 45 have outer chamfered portions 39 and 47 formed at the protruding ends, the liquid bonding material V supplied to the outer chamfered portions 39 and 47 is passed to the gap R. Can be guided appropriately. Further, the first fixing hole 25 and the second fixing hole 26 have an inner side chamfered portion 27 formed at the opening edge of the ice making substrate 13 on the outer surface 13B side, so that the liquid bonding material V is applied to the inner side chamfered portion 27. If supplied, the liquid bonding material V can be appropriately guided to the gap R. Further, on the outer surface 13 B of the ice making substrate 13 around the protruding end side of the first fixing projection 35 inserted into the first fixing hole 25 and around the protruding end side of the second fixing projection 45 inserted into the second fixing hole 26. Since the opened groove 50 is formed, it is possible to store an excess of the liquid bonding material V in the groove 50.

  Further, the horizontal partition plate 30 (the outer horizontal partition plate 30A, the inner horizontal partition plate 30B) is provided with a first fixing projection 35 corresponding to each ice making chamber 15 adjacent to the horizontal partition plate 30, Since the vertical partition plate 40 is provided with the second fixing protrusion 45 corresponding to each ice making chamber 15 adjacent to the vertical partition plate 40, the ice making chamber 15 in each horizontal partition plate 30 and each vertical partition plate 40. Therefore, the ice making chamber 15 can generate ice having a predetermined shape. In addition, since the horizontal partition plate 30 and the vertical partition plate 40 of the partition member 14 can be firmly fixed to the ice making substrate 13, the rigidity of the ice making chamber 11 is enhanced, and the ice making accompanying the temperature change in the ice making-deicing cycle. Deformation and breakage of the chamber 11 can be suppressed. In addition, the first fixing projection 35 of the horizontal partition plate 30 is provided so as to be positioned at the center between the adjacent vertical partition plates 40, 40 that define the adjacent ice making chamber 15. Since the fixing protrusion 45 is provided so as to be positioned at the center between the adjacent horizontal partition plates 30 and 30 that define the adjacent ice making chambers 15, deformation of the horizontal partition plate 30 and the vertical partition plate 40 is preferably suppressed. Can do.
